DETAILED DESCRIPTION

Description will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the disclosure as detailed in the appended claims.

In the description of the present disclosure, it should be understood that the orientation and position relationship indicated by the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential” and so on are based on the orientation or position relationship shown in the drawings and are intended only to facilitate the description of the present disclosure and simplify the description, rather than indicating or implying that the referred apparatuses or elements must have a specific orientation, must be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present disclosure.

It should be understood that “electrical connection” in the present disclosure can be understood as physical contact and electrical conduction of components; it can also be understood as the form that different components in the circuit structure are connected by physical circuits which can transmit electrical signals, such as printed circuit board (PCB), copper foil or wire. “Communication connection” can refer to the transmission of electrical signals, including wireless communication connection and wired communication connection. Wireless communication connection does not need physical media and does not belong to the connection relationship that defines the product structure. “Be connected to” and “be connected with” both can refer to mechanical connection or physical connection, that is, A and B being connected with each other or A being connected to B means that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and it is difficult to separate them.

Unless otherwise defined, all technical terms used in the embodiments of the present disclosure have the same meanings as commonly understood by those of ordinary skill in the art.

With the continuous improvement of the number and radiation performance of antennas integrated in terminal device, the stacking contradiction between the metal unibody and the antennas is becoming more and more prominent. In the related technologies, the rear-camera cover antenna, the screen black edge antenna, etc. are usually adopted, but the above schemes generally have some problems, such as complex structures and processes, high product cost and poor consistency.

In the metal unibody, the body appearance needs to be free of broken seams and slots, such that it is difficult to stack antennas. The rear-camera cover antenna adopted in the related technologies is to arrange the antenna under the cover of the rear camera of the terminal device and to hide the gap of the antenna by the cover.

The screen black edge antenna adopted in the related technologies needs to be welded on the circuit board by coaxial wire for feeding. The circuit board is fixed on the metal back cover (i.e., the metal unibody) by screws. There are two layers of the circuit board, the feeding is on the upper layer of circuit board and coupled to the lower layer of circuit board, and the lower layer of circuit board is grounded through steel sheets and other structures. Herein, the coaxial wire and the double-layer circuit board are arranged in the black edge area of the screen to radiate energy outward. This type of screen black edge antenna has a complicated structure, and the main structure is arranged in the black edge area of the screen, thereby the layout freedom is low, and the assembly difficulty is high. Meanwhile, the antenna will increase the width of the black edge of the terminal device.

Therefore, the present disclosure provides the terminal device having advantages of simple antenna component structure, simple production and assembly process, low product cost, good consistency, etc.

The technical solutions provided by the present disclosure are applicable to terminal devices adopting one or more of the following communication technologies: Blue Tooth (BT) communication technology, Global Positioning System (GPS) communication technology, Wireless Fidelity (WiFi) communication technology, Global System For Mobile Communications (GSM) communication technology, Wideband Code Division Multiple Access (WCDMA) communication technology, Long Term Evolution (LTE) communication technology, 5G communication technology and other communication technologies in the future.

The terminal devices in the embodiments of the present disclosure can be mobile phones, tablet computers, notebook computers, smart bracelets, smart watches, smart helmets, smart glasses, etc. The electronic devices can also be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistant (PDA), handheld devices with wireless communication function, computing device or other processing devices connected to wireless modem, vehicle-mounted device, electronic devices in 5G network, or electronic devices in Public Land Mobile Network (PLMN) that will evolve in the future, etc., the embodiments of the present disclosure are not limited thereto.

In order to make the purposes, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in further detail below with reference to the drawings.

The antenna component is of simple structure, has the advantages of simple production and assembly process, low product cost and good consistency.

Herein, the patch antenna is realized by using the part of the radiating metal sheet 31 parallel to the display component 1, it has good durability and easy manufacturing characteristic, and is less dependent on the volume, such that it is suitable for use in a limited space. The cavity antenna is realized by using the part of the radiating metal sheet 31 parallel to the display component 1 and the part away from the display component 1, to be able to enhance the radiation performance of the radiating metal sheet 31.

Referring to FIG. 2, in some possible implementations, the antenna component 3 is located inside the housing component 2 and within the coverage area of the display component 1; that is, the antenna component 3 is located below the screen of the terminal device, and the antenna component 3 radiates energy outward through the black edge area of the side edge of the display component 1, which is beneficial to reducing the assembly difficulty of the antenna component 3, reducing the space occupation of the black edge position of the side edge of the display component 1, and further increasing the screen ratio of the terminal device.

Exemplarily, the terminal device has a cube-like shape, the housing component 2 is located at the back of the terminal device and mainly achieves the supporting and protecting function, and the display component 1 is located at the front of the terminal device and realizes the displaying function of the terminal device.

The display component 1 is connected to the opening so as to form the front of the terminal device and realize the display function of the terminal device.

In some possible implementations, the housing component 2 is a metal unibody, and is processed by CNC, stamping and other techniques. The material of the housing component 2 can include, but not limited to, aluminum alloy, zinc alloy, stainless steel, etc. Preferably, the housing component 2 is an aluminum alloy unibody.

Referring to FIGS. 4 and 6, in some possible implementations, the first radiating part 3101 and the second radiating part 3102 are of an integrated structure, and a patch antenna structure formed by stamping, injection molding, machining etc. Alternatively, the first radiating part 3101 and the second radiating part 3102 are realized by using Flexible Printed Circuit board (FPC) or copper skin.

Exemplarily, the number of the first grounding structure 32 is, for example, one, two, three, etc. A plurality of first grounding structures 32 can be uniformly or unevenly arranged to electrically connect the radiating metal sheet 31 and the first metal part 21.

The terminal device also includes electronic elements placed inside the cavity, including, but not limited to, motherboard, battery, camera, processor, flash, microphone, speaker, etc.

In some possible implementations, the display component 1 can be used to display information inputted by or provided to users as well as various graphical user interfaces of the terminal device, and these graphical user interfaces can be composed of graphics, texts, icons, videos and any combinations thereof.

Further, the display panel is covered with a touch-sensitive surface, and when the touch-sensitive surface detects the touch operation on or near it, it transmits the same to the processor to determine the type of the touch event, thereafter the processor provides corresponding visual output on the display panel according to the type of the touch event.

Referring to FIGS. 2 and 4, in some embodiments, the housing component 2 includes the back cover part 201, and the back cover part 201 is provided parallel to the non-display side of the display component 1.

The antenna component 3 is located between the back cover part 201 and the display component 1; the side of the back cover part 201 facing the display component 1 is provided with the first metal part 21; and at least one first grounding structure 32 is electrically connected with the first metal part 21 so as to electrically ground the radiating metal sheet 31.

The antenna component 3 of the embodiment is connected with the back cover part 201 of the housing component 2, thereby assembly and grounding of the antenna component 3 are realized, such that there are the advantages of abundant assembly space and high design freedom, and the difficulty of production and assembly is correspondingly reduced. Meanwhile, the antenna component 3 does not need to occupy the black edge of the display component 1, to facilitate reducing the width of the black edge, increasing the area of the display component 1 and raising the screen ratio of the terminal device.

The antenna component 3 is electrically connected with the first metal part 21 of the back cover part 201 through the lower first grounding structure 32, so as to realize grounding of the antenna component 3. After the radiating metal sheet 31 is connected with a radio frequency module, resonance can be generated, and then energy is radiated outward, so as to realize wireless communication. The sheet-like radiation structure is convenient to be arranged inside the terminal device, has little influence on the thickness of the terminal device, and can provide enough radiation area.

Referring to FIG. 4, in some possible implementations, the first metal part 21 is located at the back cover part of the housing component 2, such that it is electrically connected to the radiating metal sheet 31 on the non-display surface side of the display component 1 through the first grounding structure 32, and the first grounding structure 32 can be located in the coverage area of the display component 1, thereby reducing space occupation of the frame area of the terminal device.

Optionally, when the housing component 2 in entirety is made of metal material, the back cover part in entirety serves as the first metal part 21. Optionally, the housing component 2 is made of metal and nonmetal materials, and the back cover part is all made of metal materials, or only the metal part arranged on the back cover part is used as the first metal part 21.

The housing component 2 includes the first metal part 21, the first metal part 21 is electrically connected with the radiating metal sheet 31 through the first grounding structure 32. As part of the housing component 2, the first metal part 21 can be used as the floor of the whole machine to realize grounding connection of the radiating metal sheet 31, such that the radiating metal sheet 31 can radiate energy outward.

Referring to FIGS. 6 and 7, in some embodiments, the second radiating part 3102 is formed by folding at least part of the edge of the first radiating part 3101 toward the first metal part 21.

At least part of the edge of the first radiating part 3101 is folded in the direction away from the display component 1 (or described as being proximate to the side where the first metal part 21 is located) to form the second radiating part 3102, such that the edge of the second radiating part 3102 is proximate to the first metal part 21, which facilitates the arrangement of the first grounding structure 32 and realizes grounding connection of the radiating metal sheet 31.

Referring to FIGS. 6 and 7, in other embodiments, the first grounding structure 32 is formed at the end of the second radiating part 3102, for example, the end of the second radiating part 3102 is folded, turned, rolled, etc., so as to increase the contact area of the second radiating part 3102 facing the first metal part 21, and thus it can be realized as the first grounding structure 32, to realize grounding connection of the radiating metal sheet 31. It has advantages of simple structure and convenient connection.

In some embodiments, at least one first grounding structure 32 includes conductive foam, conductive elastic sheet (conductive elastic sheets), and copper foil.

In some possible implementations, conductive foam refers to wrapping conductive cloth on flame retardant sponge, and after a series of treatments, it has good surface conductivity, and can be easily fixed on the device that needs to be shielded by adhesive tape.

Exemplarily, the conductive foam can be ordinary conductive foam, nickel-plated copper conductive foam, gold-plated conductive foam, carbon-plated conductive foam, tin-plated conductive foam, conductive aluminum foil foam, conductive copper foil foam, omni-directional conductive foam, Surface Mounted Technique (SMT) conductive foam, I/O conductive foam pad, etc.

In other possible implementations, the conductive elastic sheet is made of stainless steel or beryllium bronze, which can achieve the self-elastic effect by the characteristics of the material itself and achieve the contact goal. Exemplarily, the conductive elastic sheet is welded to the radiating metal sheet 31 or the first metal part 21, and extends elastically toward the other side, directly being pressed and deformed by the other side, and keeping in contact under the function of the pre-tightening force.

Referring to FIGS. 4 and 5, at least one elastic sheet member 211 is electrically connected to the surface of the first metal part 21, the number and position of the at least one elastic sheet member 211 correspond to those of the at least one first grounding structure 32, and the at least one elastic sheet member 211 is electrically connected with the at least one first grounding structure 32.

In the embodiment, at least one elastic sheet member 211 is electrically connected to the surface of the first metal part 21, the elastic sheet member 211 can be in contact with the first grounding structure 32 in a crimping manner, to realize grounding of the radiating metal sheet 31, thereby effectively reducing processing difficulty of the radiating metal sheet 31, that is, the antenna component 3.

Referring to FIGS. 4 and 6, in some embodiments, the first radiating part 3101 is a polygonal structure, at least one side edge (e.g., the first side edge 310) of the first radiating part 3101 is proximate to the edge of the display component 1, and the second radiating part 3102 is connected to at least one of the other side edges (e.g., the second side edge 311, the third side edge 312, and the fourth side edge 313) of the first radiating part 3101.

The first radiating part 3101 which is polygonal as adopted in the embodiment has the advantages of simple production and processing, and is convenient for size design, the radiation performance of the antenna component 3 can be reasonably set by size design, which reduces the difficulty of designing and debugging the antenna component 3 and ensures radiation performance of the terminal device.

As conductive materials are inevitably used in the display component 1, this will adversely affect radiation performance of the antenna component 3, thus the antenna component 3 needs to make full use of the gap of the side edge of the display component 1 to radiate energy outward. In the embodiment, the second radiating part 3102 is disposed on the other side edge of the first radiating part 3101 that is not aligned with the edge of the display component 1, and the second radiating part 3102 is not disposed on the side edge of the first radiating part 3101 that is aligned with the edge of the display component 1, such that the radiating metal sheet 31 forms a radiating structure similar to “three side edges are surrounded and one side edge is open”, and the radiated energy is concentrated on this side edge to radiate outward, and finally propagates outward through the side edge gap (i.e., the black edge area) of the display component 1, which is beneficial to improving radiation performance of the antenna assembly 3.

Referring to FIGS. 4 and 6, in some embodiments, each of the remaining side edges of the first radiating part 3101 is provided with at least one second radiating part 3102, and the end of each second radiating part 3102 is provided with at least one first grounding structure 32, respectively.

In order to ensure grounding performance of the radiating metal sheet 31, at least one second radiating part 3102 is respectively disposed on the other edges of the first radiating part 3101 except the side edge aligned with the display component 1, and the grounding of the radiating metal sheet 31 is realized by disposing the first grounding structure 32 in each second radiating part 3102, such that the current flow direction in the radiating metal sheet 31 is richer and the range of radiation frequencies that can be covered is wider.

Referring to FIGS. 4, 6, and 7, in some embodiments, the first radiating part 3101 includes a first side edge 310 proximate to the edge of the display component 1, a second side edge 311 and a third side edge 312 located at two ends of the first side edge 310 along the edge extending direction of the display component 1, and a fourth side edge 313 disposed in parallel and opposite to the first side edge 310.

The second side edge 311, the third side edge 312 and the fourth side edge 313 are respectively provided with at least one second radiating part 3102, and the end of each second radiating part 3102 is respectively provided with at least one first grounding structure 32.

The embodiment gives a specific scheme of the first radiating part 3101. Specifically, among the four side edges of the first radiating part 3101, the second side edge 311, the third side edge 312 and the fourth side edge 313, which do not correspond to the edge of the display component 1, are used for arranging the second radiating part 3102, and the first grounding structure 32 is disposed at the end of the second radiating part 3102 to realize grounding of the radiating metal sheet 31.

Exemplarily, the number of the second radiating parts 3102 in each side edge is, for example, one, two, three, etc. The second radiating part 3102 of each side edge can be the same as or different from the length of the side edge and can be reasonably selected based on the assembly requirements.

Exemplarily again, the number of the first grounding structure 32 connected to each second radiating part 3102 is, for example, one, two, three, etc. When the number of the first grounding structure 32 is two or more, the adjacent first grounding structures 32 are arranged at intervals.

Exemplarily again, in each side edge, the first grounding structures 32 to which all the second radiating parts 3102 are connected are arranged at uniform or non-uniform intervals along the side edge.

Referring to FIGS. 3, 4 and 6, in some embodiments, the terminal device further includes a circuit board 4, and at least part of the circuit board 4 extends below the first radiating part 3101.

At least one feeding point 33 is located on the lower surface of the first radiating part 3101; at least one feeding structure 41 is provided on the circuit board 4 corresponding to the at least one feeding point 33, and the at least one feeding structure 41 is electrically connected with the at least one feeding point 33.

In the embodiment, at least part of the circuit board 4 extends below the first radiating part 3101, and is electrically connected with at least one feeding point 33 on the first radiating part 3101 through at least one feeding structure 41, to realize the feeding of the antenna component 3.

Exemplarily, the number of the feeding structure 41 is the same as the number of the feeding point 33, such as one, two, three, etc. The number design of the feed structure 41 and the feed point 33 is beneficial to improving, enriching the types of feeding signals inputted by the circuit board 4 to the antenna component 3, and improving compatibility of the antenna component 3.

In some possible implementations, the circuit board 4 includes Printed Circuit Board (PCB), Flexible Printed Circuit board (FPC), soft and hard combined board, etc.

Exemplarily, the circuit board 4 is provided with electronic elements, which can include capacitors, inductors, resistors, processors, cameras, flash, microphones, etc., but not limited thereto.

In some possible implementations, the feeding structure 41 includes a feeding elastic sheet which is electrically connected with the feeding point 33.

Referring to FIGS. 3, 4 and 6, in some embodiments, at least part of the circuit board 4 extends above the first metal part 21, the circuit board 4 is provided with at least one second grounding structure 42, and the circuit board 4 is electrically connected with the first metal part 21 through at least one second grounding structure 42, to realize grounding of the circuit board 4.

Exemplarily, at least part of the circuit board 4 extends between the first radiating part 3101 and the first metal part 21, the upper surface of this part of the circuit board 4 is electrically connected to the feeding point 33 on the lower surface of the first radiating part 3101 through the feeding structure 41, to realize feeding of the antenna component 3. The lower surface of this part of the circuit board 4 is electrically connected with the first metal part 21 by using the second grounding structure 42, to realize grounding of the circuit board 4.

In this way, the upper and lower parts of the circuit board 4 are respectively provided with electrical connecting structures, such that the circuit board 4 has good compactness, stable stress and good reliability of electrical connection.

Referring to FIGS. 3 and 4, in some possible implementations, the radiating metal sheet 31 includes at least two side edges, and the feeding point 33 and the at least one first grounding structure 32 are respectively located on different side edges of the radiating metal sheet 31.

The radiating metal sheet 31 is electrically connected with the first metal part 21 through at least one first grounding structure 32 to realize grounding of the antenna component 3. The radiating metal sheet 31 generates resonance by using the current distribution area between the feeding point 33 and the grounding point, and then generates radiated energy. Therefore, the feeding point 33 and at least one first grounding structure 32 are respectively arranged at different side edges of the radiating metal sheet 31 to ensure that the radiating metal sheet 31 has enough radiating branches for energy radiation.

Referring to FIG. 8, in some embodiments, the circuit board 4 and the first radiating part 3101 are arranged adjacent to the edge of the display component 1, and at least one feeding point 33 is located on the side edge of the first radiating part 3101 near the circuit board 4 and/or near the edge of the display component 1.

In the embodiment, the feeding point 33 is arranged on the side edge of the first radiating part 3101 near the circuit board 4 and/or near the edge of the display component 1, on one hand, the feeding point 33 is as proximate to the circuit board 4 as possible, the area of the circuit board 4 is reduced, and the structural compactness of the terminal device is increased; on the other hand, the feeding point 33 is proximate to the edge of the display component 1, to make current intensity here relatively high and the radiation performance best, such that the gap of the side edge of the display component 1 can be used to radiate energy outward, thereby ensuring better radiation performance of the antenna module 3.

Exemplarily, the first radiating part 3101 includes the first side edge 310 provided with the feeding point 33 and the third side edge 313 provided with at least two first grounding structures 32.

Referring to FIGS. 4 and 11, in some embodiments, the distance L1 between the feeding point 33 and the second side edge 311 ranges from 30 mm to 50 mm, and the distance L2 between the feeding point 33 and the third side edge 312 ranges from 10 mm to 20 mm.

Referring to FIG. 4, in some embodiments, the distance L3 between the fourth side edge 313 and the first side edge 310 ranges from 20 mm to 30 mm; and the height of the first radiating part 3101 and the first metal part 21 of the housing component 2 ranges from 2 mm to 5 mm.

Therefore, the distance L1 from the feeding point 33 to the second side edge 311 can be suitable for controlling the resonance frequency of WIFI 2.4G, and its double frequency resonance frequency, which constitutes the first resonance frequency of 5G resonance. The distance L2 from the feeding point 33 to the third side 312 can be suitable for controlling the second resonant frequency of WIFI 5G, such that the antenna component 3 can realize dual-frequency WIFI radiation.

The radiating metal sheet 31 is small in volume, area and height, and occupies a small space, which is very suitable for use in the terminal device.

Referring to FIGS. 9 and 10, in some embodiments, the antenna component 3 further includes an insulating bracket 34, the insulating bracket 34 is located between the radiating metal sheet 31 and the first metal part 21, and it is used for supporting the radiating metal sheet 31.

In the terminal device of the embodiment, the thickness of the radiating metal sheet 31, which is an energy radiating component, should not be too thick, otherwise it will affect the radiation performance and increase the weight of the terminal device. Therefore, the dimensions of the radiating metal sheet 31 in the thickness direction are usually small, which also leads to poor strength and hardness of the radiating metal sheet 31, and thus the insulating bracket 34 is arranged between the radiating metal sheet 31 and the first metal part 21, and supported under the radiating metal sheet 31.
