This application relates to the electronic field, and in particular, to a foldable electronic device.
At present, foldable electronic devices are increasingly popular in the market. Take a foldable smartphone characterized by a flexible and bendable screen as an example. After the screen is bent, a dimension of the screen is similar to that of a common smartphone, and the foldable smartphone with the bent screen is easy to carry and use. After the screen is unfolded, a dimension of the screen is similar to that of a tablet computer, and entertainment or office functions are convenient to use on the unfolded screen. The foldable smartphone has advantages of the electronic device and the tablet computer, thereby meeting current consumer's needs. However, the bendable screen is more likely to break because of its large area and frequent folding activities. Therefore, screen protection is very important. Locations at which the foldable electronic device is most vulnerable to damage are end parts of a folded part of the screen. Therefore, how to effectively increase strength of the end parts of the folded part becomes a problem that cannot be avoided by the foldable electronic device.
An objective of this application is to provide a foldable electronic device with a high-strength end part appearance shielding member.
According to a first aspect, this application provides a foldable electronic device, including a first housing, a second housing, a central shaft assembly, and two shielding members. In a first direction, the first housing and the second housing are respectively connected to two opposite sides of the central shaft assembly, and the central shaft assembly implements relative rotation of the first housing and the second housing. Each shielding member includes a first shielding body, a second shielding body, and a third shielding body. The second shielding body and the third shielding body are located at two opposite sides of the first shielding body, and both the second shielding body and the third shielding body are capable of rotating relative to the first shielding body. In a second direction, the second shielding body is located at a side that is of the first shielding body and that faces the central shaft assembly and is partially stacked with the first shielding body, and the third shielding body is located at the side that is of the first shielding body and that faces the central shaft assembly and is partially stacked with the first shielding body.
In the second direction, the two shielding members are respectively located at two opposite ends of the central shaft assembly, the first shielding body is connected to one end part of the central shaft assembly, and the second shielding body is capable of sliding and rotating relative to the first housing, the third shielding body is capable of sliding and rotating relative to the second housing. The first shielding body, the second shielding body, and the third shielding body form a part of an appearance structure of the foldable electronic device. The first direction is perpendicular to the second direction.
In this embodiment of this application, the first shielding body, the second shielding body, and the third shielding body may jointly form the part of the appearance structure of the foldable electronic device. Because the second shielding body and the third shielding body are partially stacked with the first shielding body, that is, there are overlapping parts, and do not directly bear impact payloads, an impact payload on the first shielding body may be decomposed to the first housing and the second housing on two sides, to protect internal components. A possibility of dislocation between the first shielding body, the second shielding body, and the third shielding body is reduced, thereby improving structural stability of the foldable electronic device. In addition, the first shielding body, the second shielding body, and the third shielding body may shield internal components of space in which the central shaft assembly is located, so that an appearance of the foldable electronic device is more exquisite. The shielding members are respectively located at the two ends of the central shaft assembly, and may further provide uniform shielding effect for the two ends of the central shaft assembly, so that the appearance of the foldable electronic device is more concise.
In a possible implementation, appearance surfaces of the first shielding body, the second shielding body, and the third shielding body jointly form an appearance surface of the appearance structure. The appearance surface of the appearance structure faces a same direction as some appearance surfaces of the first housing and the second housing. The appearance surfaces of the second shielding body and the third shielding body are respectively located in a gap between the first shielding body and the first housing and a gap between the first shielding body and the second housing.
In an unfolded state of the foldable electronic device, the first housing and the second housing are flattened relative to each other, and the first housing, the second shielding body, the first shielding body, the third shielding body, and the second housing are sequentially arranged in the first direction. In a folded state of the foldable electronic device, the first housing and the second housing are oppositely folded, and the second shielding body and the third shielding body separately rotate by a specific angle relative to the first shielding body.
It may be understood that, in the unfolded state of the foldable electronic device, the first shielding body, the second shielding body, and the third shielding body may cover the gaps of the first housing and the second housing, so that end surfaces of a folding position of the foldable electronic device in the unfolded state is covered by the shielding members, thereby protecting the internal components and simplifying an appearance structure of the foldable electronic device. In the folded state of the foldable electronic device, the first shielding body, the second shielding body, and the third shielding body may rotate relative to each other as the central shaft assembly rotates, to complete coverage and protection of a folded central shaft end surface, and may bend at an angle as the first housing and the second housing are oppositely folded.
In a possible implementation, the first shielding body includes a main shielding body and a limiting body that is connected to the central shaft assembly. The limiting body is convexly disposed on a side surface of the main shielding body, limiting blocks are disposed on two opposite sides of the limiting body, and the second shielding body and the third shielding body are respectively located at the two opposite sides of the limiting body. The second shielding body is partially stacked with the main shielding body, and the third shielding body is partially stacked with the first shielding body. Two opposite sides of the second shielding body respectively face and have rotation gaps with a side surface of the limiting body and an end surface of the first housing, and two opposite sides of the third shielding body respectively face and have rotation gaps with the other side surface of the limiting body and an end surface of the second housing.
It may be understood that there is a rotation gap between one side of the second shielding body and the limiting body of the first shielding body, and the other side of the second shielding body is spaced opposite to an end part of the first housing. There is a rotation gap between one side of the third shielding body and the limiting body of the first shielding body, and the other side of the third shielding body is spaced opposite to an end part of the second housing. The second shielding body may rotate relative to the first housing and the first shielding body that are adjacent to each other when the foldable electronic device folds or unfolds, and the third shielding body may rotate relative to the second housing and the first shielding body that are adjacent to each other when the foldable electronic device folds or unfolds, so that the first housing, the second shielding body, the first shielding body, the third shielding body, and the second housing may sequentially rotate relative to each other and may sequentially limit each other. Therefore, a structure of the foldable electronic device in use is stable and not easily damaged.
In a possible implementation, the two opposite sides of the limiting body include concave curved surfaces, the second shielding body includes two arc-shaped convex surfaces that are oppositely disposed, and the third shielding body includes two arc-shaped convex surfaces that are oppositely disposed. One arc-shaped convex surface of the second shielding body is opposite to and has a rotation gap with one concave curved surface, and one arc-shaped convex surface of the third shielding body is opposite to and has a rotation gap with the other concave curved surface. The other arc-shaped convex surface of the second shielding body is spaced opposite to the end surface of the first housing, and the other arc-shaped convex surface of the third shielding body is spaced opposite to the end surface of the second housing. When an end part of the electronic apparatus is impacted by an external force, there are overlapping parts between the second shielding body and the first shielding body, and between the first shielding body and the third shielding body, and the first housing, the second shielding body, the first shielding body, the third shielding body, and the second housing may sequentially abut against each other and may sequentially limit each other, to buffer and reduce the impact force for each other, thereby avoiding affecting a service life of the electronic apparatus caused by damage to the shielding members.
It may be understood that, the concave curved surface is disposed to cooperate with the arc-shaped convex surface, so that rotation between the limiting body and the second shielding body or the third shielding body may be smoother and stabler, thereby ensuring reliability of folding and unfolding processes of the foldable electronic device. The concave curved surface may further limit the arc-shaped convex surface at a plurality of angles, thereby improving stability of relative motion between the first shielding body and the second shielding body, and improving structural reliability of the foldable electronic device.
In a possible implementation, the first shielding body is rotatably connected to the second shielding body and the third shielding body separately through rotating shafts, and both the second shielding body and the third shielding body are rotatably connected to the first housing and the second housing respectively through rotating shafts.
It may be understood that the second shielding body is separately connected to the first shielding body and the first housing through rotating shafts, so that a connection manner thereof is stabler, thereby ensuring that the second shielding body rotates more efficiently and stably. The third shielding body is separately connected to the first shielding body and the second housing through cylinders, so that a bonding force between the third shielding body and the first shielding body and a bonding force between the third shielding body and the end part of the second housing can be increased. When an impact occurs, dislocation is not likely to occur, and damage to another structure of the foldable electronic device is avoided as much as possible.
In a possible implementation, the first shielding body, the second shielding body, and the third shielding body are made of metal materials.
It may be understood that, in a use scenario, for example, a high temperature or a long-term bending scenario, the metal material may avoid deformation that is difficult to recover, thereby ensuring appearance exquisiteness of the foldable electronic device and improving product competitiveness.
In a possible implementation, the limiting body includes an arc-shaped end surface and two sliding surfaces that are oppositely disposed, each sliding surface is connected to one end of the arc-shaped end surface, the limiting block is located at a position of the sliding surface close to the arc-shaped end surface, each limiting block is provided with the concave curved surface, and the two concave curved surfaces are smoothly connected to two opposite ends of the sliding surface.
It may be understood that, the smooth connection between the concave curved surface and the sliding surface can simplify movement processes of the second shielding body and the third shielding body. The second shielding body and the third shielding body may respectively rotate under limits of the concave curved surfaces. In the folded state of the foldable electronic device, the sliding surface may abut against one side surface of the second shielding body or the third shielding body.
In a possible implementation, the first housing includes a first sub-bezel and a second sub-bezel that are oppositely disposed. The first sub-bezel is provided with a first end surface and a first appearance body convexly disposed on the first end surface, and the second sub-bezel is provided with a second end surface and a second appearance body convexly disposed on the second end surface. In the first direction, the first shielding body is located between the first appearance body and the second appearance body. The second shielding body is partially stacked with the first appearance body, and the arc-shaped convex surface of the second shielding body is spaced opposite to the first end surface. The third shielding body is partially stacked with the second appearance body, and the arc-shaped convex surface of the third shielding body is spaced opposite to the second end surface.
It may be understood that the first appearance body is partially stacked with the second shielding body, and the other part of the second shielding body is stacked with the first shielding body. The second appearance body is partially stacked with the third shielding body, and the other part of the third shielding body is stacked with the first shielding body. In the unfolded or folded state of the foldable electronic device, some side surfaces of the first sub-bezel, the second shielding member, the first shielding member, the third shielding member, and the third sub-bezel form one side appearance surface of the foldable electronic device, and the internal components are completely shielded from this side surface, thereby simplifying the appearance of the foldable electronic device and protecting the internal components.
In a possible implementation, the second shielding body further includes a first side surface and a second side surface that are oppositely disposed, and the third shielding body further includes a third side surface and a fourth side surface that are oppositely disposed. In the folded state of the foldable electronic device, the first side surface is spaced opposite to one sliding surface, the second side surface is spaced opposite to the first end surface, the third side surface is spaced opposite to the other sliding surface, and the fourth side surface is spaced opposite to the second end surface.
It may be understood that, in the folded state of the foldable electronic device, the first sub-bezel, the second shielding body, the first shielding body, the third shielding body, and the third sub-bezel are sequentially limited through opposite surfaces, to maintain stability of the folded state of the foldable electronic device.
In a possible implementation, the two arc-shaped convex surfaces of the second shielding body are a first arc-shaped convex surface and a second arc-shaped convex surface. The second shielding body further includes a first top surface, a first bottom surface, a first surface, and a second surface. The first side surface, the first arc-shaped convex surface, the first top surface, the second arc-shaped convex surface, the second side surface, and the first bottom surface are sequentially connected and are all connected to the first surface and the second surface. The first surface is disposed opposite to the second surface, the first side surface and the second side surface are separately disposed at an included angle relative to the first bottom surface, and the first surface is an appearance surface of the first shielding body. The two arc-shaped convex surfaces of the third shielding body are a third arc-shaped convex surface and a fourth arc-shaped convex surface. The third shielding body further includes a second top surface, a second bottom surface, a third surface, and a fourth surface. The third side surface, the third arc-shaped convex surface, the second top surface, the fourth arc-shaped convex surface, the fourth side surface, and the second bottom surface are sequentially connected and are all connected to the third surface and the fourth surface. The third surface and the fourth surface are oppositely disposed. The third side surface and the fourth side surface are separately disposed at an included angle relative to the second bottom surface, and the third surface is an appearance surface of the third shielding body.
It may be understood that, in the folded state of the foldable electronic device, the first top surface, the arc-shaped end surface of the first shielding member, and a fifth arc-shaped surface may approximately jointly form an arc profile. The arc profile may make appearances of the first shielding body, the second shielding body, and the third shielding body more concise, and conform to angles respectively obtained after the first housing and the second housing separately rotate through the central shaft assembly. In the unfolded state of the foldable electronic device, the first bottom surface, the second bottom surface, a bottom surface of the first sub-bezel, and a bottom surface of the third sub-bezel may be in one plane, so that when the foldable electronic device is in the unfolded state, an overall structure is more concise.
In a possible implementation, the rotating shafts of the first shielding body are a first rotating shaft and a second rotating shaft. A rotating shaft of the first appearance body is a third rotating shaft, and a rotating shaft of the second appearance body is a fourth rotating shaft. The second shielding body includes a first through hole and a second through hole, and the third shielding body includes a third through hole and a fourth through hole. The first rotating shaft penetrates through the first through hole, the second shielding body rotates relative to the first shielding body through the first rotating shaft, the second rotating shaft penetrates through the third through hole, the third shielding body rotates relative to the first shielding body through the second rotating shaft, the third rotating shaft penetrates through the second through hole, the first housing and the second shielding body rotate through the third rotating shaft, the fourth rotating shaft penetrates through the fourth through hole, and the second housing and the third shielding body rotate through the fourth rotating shaft.
In a possible implementation, the foldable electronic device includes a display, and the first housing, the second housing, the central shaft assembly, and the shielding members form a main body. The display is stacked with the main body, and the display includes a first part, a second part, and a third part that connects the first part and the second part. The first housing carries the first part, the second housing carries the second part, and the central shaft assembly supports the third part. The central shaft assembly drives the third part to bend.
In the folded state of the foldable electronic device, the first part and the second part face each other, or the first part and the second part face away from each other.
It may be understood that, in the folded state of the foldable electronic device, the first housing and the second housing separately rotate through the central shaft assembly, and are close to each other. Surfaces that are of the first housing and the second housing and that carry the display face each other. After being folded, the display is on an inner side of a structure of the main body. Alternatively, surfaces that are of the first housing and the second housing and that carry the display face away from each other. After being folded, the display is on an outer side of the structure. In other words, the foldable electronic device may be an inner foldable screen electronic device or an outer foldable screen electronic device. The first shielding body, the second shielding body, and the third shielding body may jointly form the part of the appearance structure of the foldable electronic device. Because the second shielding body and the third shielding body are partially stacked with the first shielding body, that is, there are overlapping parts, and do not directly bear impact payloads, an impact payload on the first shielding body may be decomposed to the first housing and the second housing on two sides, to protect the display from being impacted.
In a possible implementation, the central shaft assembly includes a base, a first rotating part, and a second rotating part. The base includes a first end and a second end, the first rotating part includes a third end and a fourth end, and the second rotating part includes a fifth end and a sixth end. Two first shielding bodies are respectively connected to the first end and the second end, two second shielding bodies are respectively located at the third end and the fourth end, and two third shielding bodies are respectively disposed at the fifth end and the sixth end.
It may be understood that the first shielding body may be directly connected to the two ends of the base. The second shielding body may not be connected to the first rotating part, and the third shielding body may not be connected to the second rotating part, and only positions are mutually limited. When the central shaft assembly is impacted, the gap between the first shielding body and the second shielding body, and the gap between the first shielding body and the third shielding body are small. The first shielding body, the second shielding body, and the third shielding body may sequentially limit each other, to buffer the external force. When the central shaft assembly is impacted by the external force, the first shielding body may bear a main impact payload, and the second shielding body and the third shielding body may not directly bear impact payloads, but buffer the external force on the first shielding body. In addition, positions of the base and the first rotating part limit each other, and positions of the base and the second rotating part limit each other, thereby reducing displacement of dislocation of the base, the first rotating part, and the second rotating part under the impact of the external force, reducing deformation of the display, and enhancing mechanical strength of the foldable electronic device. Similarly, when the second shielding body or the third shielding body is impacted by the external force, some energy of the impact may be transferred to the first shielding body, to disperse the impact force, thereby reducing dislocation of the first shielding body, the second shielding body, the third shielding body, and the central shaft assembly, and effectively protecting the display. When the foldable electronic device falls in the unfolded state, the first housing or the second housing is impacted first, and the impact force may be transferred from the first sub-bezel to the second shielding body adjacent to the first sub-bezel. Alternatively, the third sub-bezel transfers the impact force to the third shielding body, and the second shielding body and the third shielding body transfer a part of the impact force to the first shielding body again, to disperse the impact force and reduce dislocation of the first shielding body, the second shielding body, the third shielding body, and the central shaft assembly, and effectively protecting the display. Because the second shielding body is not directly connected to the first rotating part, movement of the second shielding body and the first rotating part does not affect each other. When the second shielding body is impacted by the external force, a motion function of the first rotating part is not affected, thereby reducing the impact of the first rotating part on the display and protecting the display.

At present, foldable electronic devices are increasingly popular in the market. Take a foldable smartphone characterized by a flexible and bendable screen as an example. After the screen is bent, a dimension of the screen is similar to that of a common smartphone, and the foldable smartphone with the bent screen is easy to carry and use. After the screen is unfolded, a dimension of the screen may be similar to that of a tablet computer, and entertainment or office functions are convenient to use on the unfolded screen. The foldable smartphone has advantages of the electronic device and the tablet computer, thereby meeting current consumer's needs. However, the bendable screen is more likely to break because of its large area or frequent folding activities. Therefore, screen protection is very important. Locations at which the foldable electronic device is most vulnerable to damage are end parts of a folded part of the screen. Therefore, how to effectively increase strength of the screen end parts of the folded part becomes a problem that cannot be avoided by the foldable electronic device.
Based on this, this application provides a foldable electronic device, to effectively improve strength of end parts of a foldable part of the foldable electronic device, thereby protecting internal components of the foldable electronic device.

The first housing 200 and the second housing 300 respectively support the first part 110 and the second part 120. The central shaft assembly 400 drives the first housing 200 and the second housing 300 to be folded and unfolded. The first housing 200 and the second housing 300 may be oppositely close to each other to be folded until the foldable electronic device 1000 is in a folded state. The first housing 200 and the second housing 300 may be oppositely away from each other to be unfolded until the foldable electronic device 1000 is in an unfolded state, and the central shaft assembly 400 supports the foldable third part 130 of the display 100.
In a first direction (the Y-axis direction), the first housing 200 and the second housing 300 are respectively connected to two opposite sides of the central shaft assembly 400, and the central shaft assembly 400 implements relative rotation of the first housing 200 and the second housing 300. Each shielding member 500 includes a first shielding body 510, a second shielding body 520, and a third shielding body 530, the second shielding body 520 and the third shielding body 530 are located at two opposite sides of the first shielding body 510, and both the second shielding body 520 and the third shielding body 530 may rotate relative to the first shielding body 510.

It should be noted that
In daily use, an electronic device with a large screen can improve user experience in some scenarios, but the electronic device with a large screen is inconvenient for daily carrying. Emergence of the foldable electronic device resolves the problem that the electronic device with a large screen is not easy to carry. When the foldable electronic device 1000 is in an unfolded state, a screen dimension of the electronic device may be far greater than that of a common electronic device, to implement large-screen display and operation functions of the foldable electronic device 1000, so that user experience can be well improved when a user watches a video or performs entertainment. When the user does not need the large screen, the foldable electronic device 1000 may be folded, and a display 100 of a foldable electronic device 1000 whose folded electronic device screen is on an outer side is half of that of the foldable electronic device 1000 in the unfolded state. This facilitates one-hand operation by the user. The display 100 is located between the first housing 200 and the second housing 300. The first housing 200 and the second housing 300 protect a display surface of the display 100, to greatly reduce a probability that the display 100 is damaged. In addition, an overall dimension is reduced, so that the foldable electronic device is easy to carry.

Each third sub-bezel 321 includes a second end surface 3210 and a second appearance body 3211. The second end surface 3210 faces away from the fourth sub-bezel 322. The second appearance body 3211 is convexly disposed on the second end surface 3210. In the X-axis direction, that is, a thickness direction of the third sub-bezel 321, a thickness of the second appearance body 3211 is less than a thickness of the third sub-bezel 321. The second appearance body 3211 includes a second appearance surface (not marked in the figure) and a second inner side surface 3211a that faces away from the second appearance surface. The second appearance surface is exposed to the outside of the electronic device, and is coplanar with an outer surface of the third sub-bezel 321. The second inner side surface 3211a is connected to the second end surface 3210 at an included angle. In this embodiment, the included angle is 90 degrees, which facilitates assembly with the shielding member 500.
The central shaft assembly 400 is disposed between the first housing 200 and the second housing 300, and is separately connected to the first housing 200 and the second housing 300 through the first mounting groove and the second mounting groove. In an unfolded state of the foldable electronic device 1000, the first housing 200, the second housing 300, and the central shaft assembly 400 jointly support the display 100. The first part 110 is opposite to the first housing 200, the second part 120 is opposite to the second housing 300, and the third part 130 is opposite to the central shaft assembly 400. In a folded state of the foldable electronic device 1000, the first housing 200 and the second housing 300 separately rotate through the central shaft assembly 400, and are close to each other. Surfaces that are of the first housing 200 and the second housing 300 and that carry the display 100 face each other. After being folded, the display 100 is on an inner side of a structure of the main body. In an implementation, surfaces that are of the first housing 200 and the second housing 300 and that carry the display 100 face away from each other. After being folded, the display 100 is on an outer side of the structure. In other words, the foldable electronic device 1000 may be an inner foldable screen electronic device or an outer foldable screen electronic device. This is not limited herein
The central shaft assembly 400 includes a base 410, a first rotating part 420, and a second rotating part 430. The first rotating part 420 and the second rotating part 430 are symmetrically connected to two sides of the base 410. The base 410 and the first rotating part 420 may be rotatably connected to each other, and the base 410 and the second rotating part 430 may be rotatably connected to each other. A specific structure thereof may be a rotating shaft mechanism in the conventional technology. This is not described herein. The central shaft assembly 400 is configured to support the display 100. The first rotating part 420 is located in the first mounting groove of the first housing 200 and is rotatably connected to the first housing 200 and the base 410. The second rotating part 430 is disposed in the second mounting groove of the second housing 300 and is rotatably connected to the second housing 300 and the base 410. When the foldable electronic device 1000 is unfolded and folded, the first rotating part 420 and the second rotating part 430 separately rotate relative to the base 410. When unfolding and folding actions are completed, the first rotating part 420 and the base 410 limit each other, the base 410 and the second rotating part 430 limit each other, and the first rotating part 420, the base 410, and the second rotating part 430 and both the first housing 200 and the second housing 300 limit each other, so that the foldable electronic device 1000 can be positioned in the unfolded state and can be positioned in the folded state or in an intermediate state, and a structure of the foldable electronic device 1000 can also be prevented from being damaged due to excessive rotation of the first housing 200 and the second housing 300.

The base 410 includes a first end 411 and a second end 412, the first rotating part 420 includes a third end 421 and a fourth end 422, and the second rotating part 430 includes a fifth end 431 and a sixth end 432.

The first end 411 of the base 410 may be connected to a first connection surface 5122 of one limiting body 512, and the second end 412 of the base 410 may be connected to a first connection surface 5122 of another limiting body 512.
Two limiting blocks 5124 are convexly disposed on the limiting body 512. The limiting blocks 5124 are located at positions of the two sliding surfaces 5121 close to the arc-shaped end surface 5123. The limiting block 5124 includes a concave curved surface 5124a. The concave curved surface 5124a is smoothly connected to the sliding surface 5121.

Two opposite sides of the third shielding body 530 rotatably abut against the other side surface of the limiting body 512 and an end surface of the second housing 300 respectively.

In a possible implementation, the first shielding body 510, the second shielding body 520, and the third shielding body 530 are made of metal materials. In a use scenario, for example, a high temperature or a long-term bending scenario, the metal material may avoid deformation that is difficult to recover, thereby ensuring appearance exquisiteness of the foldable electronic device and improving product competitiveness.

The foldable electronic device 1000 is in the unfolded state. The two shielding members 500 are symmetric. An assembly relationship between a shielding member 500 and the central shaft assembly 400 is described by using one shielding member 500 as an example.
The central shaft assembly 400 is mounted between the first housing 200 and the second housing 300, and the shielding member 500 is located between the first sub-bezel 221 and the third sub-bezel 321 (that is, between the first housing 200 and the second housing 300). As shown in
The second shielding body 520, the first shielding body 510, and the third shielding body 530 are sequentially arranged in a width direction (the Y-axis direction), and a part of the second shielding body 520 and a part of the third shielding body 530 are stacked with the first shielding body 510. The second shielding body 520 is spaced opposite to the limiting body 512, and there is a rotation gap between the first arc-shaped convex surface 5201 and the concave curved surface 5124a of the limiting block 5124. The third shielding body 530 is spaced opposite to the other side of the limiting body 512 of the first shielding body 510, and there is a rotation gap between the third arc-shaped convex surface 5301 and the concave curved surface 5124a of the limiting block 5124. When the shielding member 500 is impacted, there are overlapping parts between the second shielding body 520 and the first shielding body 510, and between the first shielding body 510 and the third shielding body 530, and the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 sequentially limit each other.
The main shielding body appearance surface 5110 of the first shielding body 510 and an outer side surface of the first sub-bezel 221 face a same direction, and may be coplanar. Specifically, the main shielding body appearance surface 5110 and an outer side surface of the first appearance body 2211 face a same direction. The main shielding body appearance surface 5110 of the first shielding body 510 and an outer side surface of the third sub-bezel 321 face a same direction, and may be coplanar. Specifically, the main shielding body appearance surface 5110 and an outer side surface of the second appearance body 3211 face a same direction. The first surface 5206 of the second shielding body 520 is located in a gap between the first shielding body 510 and the first sub-bezel 221. The third surface 5306 of the third shielding body 530 is located in a gap between the first shielding body 510 and the third sub-bezel 321. The second shielding body 520, the first shielding body 510, and the third shielding body 530 are jointly connected to the first housing and the second housing and shield the central shaft assembly 400. Appearance surfaces of the first shielding body 510, the second shielding body 520, and the third shielding body 530 jointly form an appearance surface of the appearance structure. In other words, the main shielding body appearance surface 5110 of the first shielding body 510, the first surface 5206 of the second shielding body 520, the third surface 5306 of the third shielding body 530, the outer side surface of the first bezel 220, and an outer side surface of the second bezel 320 jointly serve as outer end surfaces of two ends of the main body, that is, the appearance surface.
The appearance surface of the appearance structure faces a same direction as some appearance surfaces of the first housing 200 and the second housing 300, and the appearance surfaces of the second shielding body 520 and the third shielding body 530 are respectively located in a gap between the first shielding body 510 and the first housing 200 and a gap between the first shielding body 510 and the second housing 300. When the foldable electronic device 1000 is in a folded state, the first housing 200 and the second housing 300 are oppositely folded through the central shaft assembly 400, and the second shielding body 520 and the third shielding body 530 separately rotate by a specific angle relative to the first shielding body 510 as the central shaft assembly 400 rotates.
Side surfaces of the first sub-bezel 221, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the third sub-bezel 321 jointly form one side appearance surface of the foldable electronic device 1000. The first shielding body 510, the second shielding body 520, and the third shielding body 530 jointly cover a spacing between the first sub-bezel 221 and the third sub-bezel 321. Specifically, the second shielding body 520 has overlapping parts with both the first shielding body 510 and the first appearance body 2211 of the first sub-bezel 221, so that the first sub-bezel 221, the second shielding body 520, and the first shielding body 510 are sequentially stacked, and there are no gaps in the Y direction. Same as the second shielding body 520, the third shielding body 530 has overlapping parts with both the second appearance body 3211 of the third sub-bezel 321 and the first shielding body 510, and there are no gaps between the third sub-bezel 321 and the third shielding body 530, and between the third shielding body 530 and the first shielding body 510 in the Y direction. It may be understood that, in an unfolded state or a folded state of the foldable electronic device 1000, there are no gaps between the second shielding body 520 and the first shielding body 510, and between the first shielding body 510 and the third shielding body 530, and there are no gaps between the second shielding body 520, the first shielding body 510, and the third shielding body 530 and both the first housing 200 and the second housing 300, so that the central shaft assembly and the internal components of the foldable electronic device 1000 are shielded, thereby protecting the internal components and hiding the internal components. Therefore, the appearance of the foldable electronic device 1000 is more concise and beautiful.
Specifically, the second shielding body 520 includes two arc-shaped convex surfaces that are oppositely disposed, that is, the first arc-shaped convex surface 5201 and the second arc-shaped convex surface 5203. The third shielding body 530 includes two arc-shaped convex surfaces that are oppositely disposed, that is, the third arc-shaped convex surface 5301 and the fourth arc-shaped convex surface 5303. One arc-shaped convex surface of the second shielding body 520 and one arc-shaped convex surface of the third shielding body are respectively disposed opposite to the two concave curved surfaces 5124a. In other words, the first arc-shaped convex surface 5201 of the second shielding body 520 is spaced opposite to and has a rotation gap with the concave curved surface 5124a of the limiting body 512, and the third arc-shaped convex surface 5301 of the third shielding body 530 is spaced opposite to and has a rotation gap with the other concave curved surface 5124a of the limiting body 512 of the first shielding body 510. The other arc-shaped convex surface of the second shielding body 520 and the other arc-shaped convex surface of the third shielding body 530 respectively slide relative to the end surface of the first housing 200 and the end surface of the second housing 300 and are rotatable. In other words, the second arc-shaped convex surface 5203 of the second shielding body 520 is opposite to the first end surface 2210 and has a gap, the first surface 5206 of the second shielding body 520 is opposite to the first inner side surface 2211a of the first sub-bezel 221, and the first end surface 2210 of the first sub-bezel 221 is opposite to the second arc-shaped convex surface 5203 and has a gap.
An unfolded state of the third shielding body 530 is similar to that of the second shielding body 520. The fourth arc-shaped convex surface 5303 of the third shielding body 530 is opposite to the second end surface 3210 and has a gap, the third surface 5306 of the third shielding body 530 is opposite to the second inner side surface 3211a of the third sub-bezel 321, and the second end surface 3210 of the third sub-bezel 321 is opposite to the fourth arc-shaped convex surface 5303 and has a gap.
The first shielding body 510 is fastened to the base 410, and the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 sequentially limit each other and keep stable through cooperation, to limit a position of the shielding member 500. In addition, the central shaft assembly 400 implements flattened states and positioning of the first housing 200 and the second housing 300, limits relative positions of the second shielding body 520, the first shielding body 510, and the third shielding body 530 in the Y-axis direction, and limits relative positions of the second shielding body 520, the first shielding body 510, and the third shielding body 530 in the Y-axis direction with the first housing 200 and the second housing 300. In other words, when the first housing 200 and the second housing 300 are flattened relative to each other, spreading angles of the second shielding body 520, the first shielding body 510, and the third shielding body 530 are determined through the central shaft assembly.
When the foldable electronic device 1000 is impacted by an external force, sequential abutting against each other between the first sub-bezel 221, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the third sub-bezel 321 reduces displacement of dislocation of each component. The first shielding body 510 has overlapping positions with the second shielding body 520 and the third shielding body 530, an overlapping position between the first shielding body 510 and the second shielding body 520 and an overlapping position between the first shielding body 510 and the third shielding body 530 may strengthen mechanical strength of an appearance housing of the foldable electronic device 1000 in this part of the central shaft assembly 400, thereby avoiding damage to the foldable electronic device 1000 caused by insufficient strength of a joint between the first shielding body 510 and the second shielding body 520 and a joint between the first shielding body 510 and the third shielding body 530. A middle frame assembly of the foldable electronic device 1000 presents seamless all-metal appearance effect, thereby improving exquisiteness of the foldable electronic device 1000.
In a possible embodiment, the first shielding body 510 may be connected to two ends of the base 410. The second shielding body 520 is not directly connected to the first rotating part 420, and the third shielding body 530 is not directly connected to the second rotating part 430, and only positions are mutually limited. The first shielding body 510, the first mounting groove, and the first sub-bezel 221 may jointly limit the second shielding body 520, and the first shielding body 510, the second mounting groove, and the third sub-bezel 321 may jointly limit the third shielding body 530.
When the central shaft assembly 400 is impacted, a gap between the first shielding body 510 and the second shielding body 520, and a gap between the first shielding body 510 and the third shielding body 530 are small, to buffer the external force. When an end part of the central shaft assembly 400 is impacted by the external force, the first shielding body 510 may bear a main impact payload. Because the second shielding body 520 and the third shielding body 530 partially overlap the first shielding body 510, and do not directly bear impact payloads, the second shielding body 520 may transfer the impact payload on the first shielding body 510 to the first sub-bezel 221, and the third shielding body 530 may transfer the impact payload on the first shielding body 510 to the third sub-bezel 321. The impact payload received by the first shielding body 510 is decomposed to the second shielding body 520 and the third shielding body 530, to buffer the external force on the first shielding body 510. In addition, positions of the base 410 and the first rotating part 420 limit each other, and positions of the base 410 and the second rotating part 430 limit each other, thereby reducing displacement of dislocation of the base 410, the first rotating part 420, and the second rotating part 430 under the impact of the external force, reducing deformation of the display 100, and enhancing mechanical strength of the foldable electronic device 1000. Similarly, when the second shielding body 520 or the third shielding body 530 is impacted by the external force, some energy of the impact may be transferred to the first shielding body 510, to disperse the impact force, thereby effectively protecting the display 100. When the foldable electronic device 1000 falls in an unfolded state, the first housing 200 or the second housing 300 is impacted first, and the impact force may be transferred from the first sub-bezel 221 to the second shielding body 520 adjacent to the first sub-bezel 221. Alternatively, the third sub-bezel 321 transfers the impact force to the third shielding body 530, and the second shielding body 520 and the third shielding body 530 transfer a part of the impact force to the first shielding body 510 again, to disperse the impact force, thereby protecting the display 100.

When the foldable electronic device 1000 is impacted in the folded state, the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 may be sequentially in contact with each other for limiting, to disperse an impact payload. Specifically, when the foldable electronic device 1000 is impacted in the folded state, the first end surface 2210 and the second side surface 5204 may abut against each other, so that the first housing 200 and the second shielding body 520 sequentially limit each other. The first side surface 5200 and one sliding surface 5121 are in contact with each other for limiting, and the third side surface 5300 and the other sliding surface 5121 are in contact with each other for limiting, so that the second shielding body 520, the first shielding body 510, and the third shielding body 530 may sequentially abut against each other for limiting. The fourth side surface 5304 and the second end surface 3210 may be in contact with each other for limiting, so that the third shielding body 530 and the second housing 300 may abut against each other for limiting.
It may be understood that, when the foldable electronic device 1000 is in the folded state, when an end part of a foldable part is impacted by a force in a specific direction, gaps sequentially between the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 may provide buffer spaces. In addition, the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 may sequentially abut against each other to disperse an impact payload, to protect a structure of the foldable electronic device 1000.
For example, when the foldable electronic device 1000 is in the folded state, side surfaces of the third surface 5114 of the first shielding body 510, the first top surface 5202 of the second shielding body 520, and the second top surface 5302 of the third shielding body 530 may jointly form an arc profile. The arc profile may make appearances of the first shielding body 510, the second shielding body 520, and the third shielding body 530 more concise, and conform to angles of the first housing 200 and the second housing 300 after the first housing 200 and the second housing 300 rotate through the central shaft assembly 400. It should be noted that, when the foldable electronic device 1000 is in the folded state, angle positioning presented by the first shielding body 510, the second shielding body 520, and the third shielding body 530, and angle limiting presented by the second shielding body 520 and the third shielding body 530 with the first housing 200 and the second housing 300 are implemented through the central shaft assembly 400. In other words, as angle positioning is performed on the first housing 200 and the second housing 300 through the central shaft assembly 400, angles of the first shielding body 510, the second shielding body 520, and the third shielding body 530 are also positioned, thereby ensuring stability of the shielding member 500.

Specifically, the main shielding body 511 includes a first rotating shaft 511a and a second rotating shaft 511b, and shaft directions of the first rotating shaft 511a and the second rotating shaft 511b may be perpendicular to or approximately an angle of a right angle with the main shielding body 511. The first rotating shaft 511a and the second rotating shaft 511b are convexly disposed on the connection surface 5111 of the first shielding body 510, and axis lines of the first rotating shaft 511a and the second rotating shaft 511b may be perpendicular to the connection surface 5111. One concave curved surface 5124a faces the first rotating shaft 511a, and the other concave curved surface 5124a faces the second rotating shaft 511b.
The second shielding body 520 is provided with a first through hole 520a and a second through hole 520b. The first through hole 520a and the second through hole 520b penetrate through the first surface 5206 and the second surface 5207. Each first appearance body 2211 includes a third rotating shaft 2211b. The third rotating shaft 2211b is convexly disposed on the first inner side surface 2211a of the first appearance body 2211. An axis line direction of the third rotating shaft 2211b may be perpendicular to the first inner side surface 2211a. The third shielding body 530 includes a third through hole 530a and a fourth through hole 530b. The third through hole 530a and the fourth through hole 530b penetrate through the third surface 5306 and the fourth surface 5307. Each second appearance body 3211 includes a fourth rotating shaft 3211b. The fourth rotating shaft 3211b is convexly disposed on the second inner side surface 3211a of the second appearance body 3211. An axis line direction of the fourth rotating shaft 3211b may be perpendicular to the second inner side surface 3211a. The first through hole 520a of the second shielding body 520 is connected to the first rotating shaft 511a, and the second through hole 520b of the second shielding body 520 is connected to the third rotating shaft 2211b. The third through hole 530a of the third shielding body 530 is connected to the second rotating shaft 511b, and the fourth through hole 530b is connected to the fourth rotating shaft 3211b. When a folding or unfolding action is performed on the foldable electronic device 1000, the first rotating shaft 511a may rotate in the first through hole 520a, the second rotating shaft 511b may rotate in the third through hole 530a, the third rotating shaft 2211b may rotate in the second through hole 520b, and the fourth rotating shaft 3211b may rotate in the fourth through hole 530b.
The first shielding body 510 may further include a first fastener 511c and a second fastener 511d. After assembly, a part of the second shielding body 520 is stacked with the first shielding body 510, a part of the second shielding body 520 is stacked with the first appearance body 2211, the first rotating shaft 511a penetrates through the first through hole 520a, the first fastener 511c is connected to an end of the first rotating shaft 511a, that is, is located at the second surface 5207. The second shielding body 520 is located between the connection surface 5111 and the first fastener 511c. The first rotating shaft 511a penetrates through the first through hole 520a and is locked through the first fastener 511c. In other words, the second shielding body 520 is rotatably connected to the first shielding body 510 and the first sub-bezel 221 separately. The first fastener 511c enables the second shielding body 520 to rotate only using an axis line direction of the first rotating shaft 511a as a central axis, thereby reducing sliding of the second shielding body 520 in the axis line direction of the first rotating shaft 511a. The second fastener 511d is connected to an end of the second rotating shaft 511b, and the third shielding body 530 is disposed between the connection surface 5111 and the second fastener 511d. The second fastener 511d enables the third shielding body 530 to rotate only using an axis line direction of the second rotating shaft 511b as a central axis, thereby reducing sliding of the third shielding body 530 in the axis line direction of the second rotating shaft 511b.
The first appearance body 2211 may include a third fastener 2211c. After assembly, the third fastener 2211c is connected to an end of the third rotating shaft 2211b, the third fastener 2211c is located at the second surface 5207, and the second shielding body 520 is disposed between the first inner side surface 2211a and the third fastener 2211c. The third rotating shaft 2211b penetrates through the second through hole 520b and is locked through the third fastener 2211c. The third fastener 2211c enables the second shielding body 520 to rotate only using an axis line direction of the third rotating shaft 2211b as a central axis, thereby reducing sliding of the second shielding body 520 in the axis line direction of the third rotating shaft 2211b.
The second appearance body 3211 may include a fourth fastener 3211c. After assembly, the fourth fastener 3211c is connected to an end of the fourth rotating shaft 3211b, the fourth fastener is located at the fourth surface 5307, and the third shielding body 530 is disposed between the second inner side surface 3211a and the fourth fastener 3211c. The fourth rotating shaft 3211b penetrates through the fourth through hole 530b and is locked through the fourth fastener 3211c. The fourth fastener 3211c enables the third shielding body 530 to rotate only using an axis line direction of the fourth rotating shaft 3211b as a central axis, thereby reducing sliding of the third shielding body 530 in the axis line direction of the fourth rotating shaft 3211b.
Refer to
In this embodiment, the first shielding body 510 is directly connected to the base 410, the second shielding body 520 is not connected to the first rotating part 420, and the third shielding body 530 is not connected to the second rotating part 430. During assembly, the second shielding body 520 and the third shielding body 530 are assembled after the central shaft assembly 400 is fastened to the first housing 200 and the second housing 300. In other words, after the through holes of the second shielding body 520 and the third shielding body 530 are connected to the cylinders, the fasteners are used to limit the ends of the cylinders, to prevent the second shielding body 520 and the third shielding body 530 from falling off. Because the second shielding body 520 is not directly connected to the first rotating part 420, movement of the second shielding body 520 and the first rotating part 420 does not affect each other. When the second shielding body 520 is impacted by the external force, a motion function of the first rotating part 420 is not affected, thereby reducing the impact of the first rotating part 420 on the display 100 and protecting the display 100. The connection relationship between the third shielding body 530 and the first rotating part 420 is the same as the connection relationship between the second shielding body 520 and the first rotating part 420, and is not described herein again. The first shielding body 510, the second shielding body 520, the third shielding body 530, the first housing 200, and the second housing 300 may form an enclosure frame together to protect the interior of the foldable electronic device 1000. In addition, when the foldable electronic device 1000 falls, a motion action of the central shaft assembly 400 is protected, and an abnormal action of the central shaft assembly 400 is reduced, thereby improving falling reliability of the display 100. The abnormal action, for example, dislocation of the base 410, the first rotating part 420, or the second rotating part 430 causes damage to the display 100.
