Embodiments of
In the wireless power apparatus 100, the first magnetic piece 130 is disposed on the housing 110 so that the equipment body 310 can be adsorbed to the housing. In this manner, the use of the transmission line between the wireless power apparatus 100 and the equipment body 310 is avoided, a number of parts is reduced, and the use is more convenient. In a second aspect, the wireless power source 100 and the equipment body 310 can be connected to be an integrated structure, so that the footprint during use is reduced. In a third aspect, the apparatus charges the equipment body 310 through the wireless power supply assembly 150, avoiding an opening penetrating through the housing 110 for the wireless power supply assembly 150, so that the sealing performance of the wireless power apparatus 100 is improved and a better waterproofing is obtained.
It is known that when two objects are directly pulled in a direction of an adsorption force in a state of magnetic adsorption, the adsorption force needs to be overcome, and the two objects are difficult to separate from each other. In this embodiment, an upper end surface of the housing 110 includes a first adsorption portion 111 and a power supply portion 112, the first adsorption portion 111 is located at an outer periphery of the power supply portion 112, the wireless power supply assembly 150 is disposed on the power supply portion 112, multiple first magnetic pieces 130 are provided, and the multiple first magnetic pieces 130 are dispersedly disposed on the first adsorption portion 111, the multiple first magnetic pieces 130 may be in one-to-one correspondence with the multiple first adsorption pieces 320 on the equipment body 310. The arrangement of the multiple first magnetic pieces 130 allows a greater adsorption force when the multiple first magnetic pieces 130 are adsorbed to the multiple first adsorption pieces 320 on the equipment body 310. In addition, the arrangement of the multiple first magnetic pieces 130 and the multiple first adsorption pieces 320 allows an accurate alignment of the housing 110 with the equipment body 310. When the equipment body 310 needs to be separated from the housing 110, the wireless power apparatus 100 simply needs to be screwed relative to the equipment body 310. The multiple first magnetic pieces 130 are uniformly dispersed around the power supply portion 112, which makes alignment of the equipment body 310 with the wireless power apparatus 100 simpler. After roughly aligning the equipment body 310 with the wireless power apparatus 100, alignment of the equipment body 310 with the wireless power apparatus 100 can be achieved through the adsorption of the multiple first magnetic pieces 130 and the multiple first adsorption pieces 320. The first magnetic piece 130 may be a magnet, and the first adsorption piece 320 may be a magnet or may be a material capable of being adsorbed by a magnet.
In this embodiment, a magnetic ring 180 is mounted within the housing 110, the magnetic ring 180 can be adsorbed to and aligned with a ring-shaped adsorption piece of the equipment body 310, and a specific structure may refer to an Magsafe structure.
To save space when multiple wireless power apparatuses 100 are in storage, in this embodiment, a lower end of the housing 110 is provided with multiple second magnetic pieces 160, so that when two housings 110 are stacked, the second magnetic pieces 160 on the upper housing 110 may be adsorbed to the first magnetic pieces 130 of the lower housing 110.
In this embodiment, when multiple housings 110 are stacked, first batteries of the wireless power apparatuses 100 are connected in series, so that a voltage provided outwardly is increased. Specifically, the connection may be made by a wireless induction technology or a contact. With regard to the manner of the connection by the contact, specifically, the upper end and the lower end of the housing 110 are each provided with a positive contact and a negative contact, and when two wireless power apparatuses 100 are stacked, one of the two wireless power apparatuses 100 above is defined as a first power source, and the other of the two wireless power apparatuses 100 below is defined as a second power source. A positive contact on a lower end of the first power source abuts a positive contact on an upper end of the second power source abut, and a negative contact on the lower end of the first power source abuts a negative contact on the upper end of the second power source. The uppermost wireless power apparatus 100 can provide wireless power to the equipment body 310 or provide power through the positive contact and the negative contact. The positive contact and the negative contact are disposed at an eccentric position of the wireless power apparatuses 100, not at a central position of the upper end, and this arrangement allows an electrical connection between the stacked wireless power apparatuses 100 in storage to be avoided by rotating two adjacent wireless power apparatuses 100 by 90 degrees. In this embodiment, four first magnetic pieces 130 and four second magnetic pieces 160 are provided, where an included angle between any two adjacent first magnetic pieces 130 is 90 degrees, and an included angle between any two adjacent second magnetic pieces 160 is 90 degrees.
To avoid an accidental collision in the power supply process, which may cause separation between the equipment body 310 and the wireless power apparatus 100, resulting in the end of power supply, in this embodiment, the first adsorption portion 111 has a structure of a spherical surface, which bends towards the lower end of the housing 110 in a direction away from the power supply portion 112. A central vertical line of the power supply portion 112 passes through a spherical center of the spherical surface. In another embodiment, the first adsorption portion 111 has a structure of a spherical surface, which bends towards the lower end of the housing 110 in a direction away from the power supply portion 112.0, and the second adsorption portion 113 is parallel to the first adsorption portion 111. That is, the second adsorption portion 113 is formed by biasing the first adsorption portion 111. Such configuration enables stacking of multiple housings 110. To fit the first adsorption portion 111, an end of the equipment body 310 mating with the wireless power apparatus 100 also has a structure of a spherical surface which is in a groove shape. This arrangement allows the wireless power apparatus 100 and the equipment body 310 to tend to go away from each other during the process of pushing against the wireless power supply apparatus 100 from the side. In this case, a large force is needed, avoiding separation of the equipment body 310 from the wireless power apparatus 100 due to an accidental touch. It is noted that the above-described structure does not affect the relative rotation of the wireless power apparatus 100 and the equipment body 310. In a rotating process, an adsorption force between the first magnetic piece 130 and the first adsorption piece 320 is small, and the wireless power apparatus 100 and the equipment body 310 can be easily separated from each other when the first magnetic piece 130 and the first adsorption piece 320 are completely misaligned.
In another implementation of this embodiment, the first adsorption portion 111 may have a structure of a conical surface, and the central vertical line of the power supply portion 112 passes through the vertex of the conical surface. In this implementation, the first adsorption portion 111 has a structure of a conical surface, and the second adsorption portion 113 may also have the conical surface structure. An end of the equipment body 310 mating with the wireless power apparatus 100 also has a structure of a conical surface, which is in a groove shape.
The lower end of the housing 110 includes the second adsorption portion 113 and a charging portion 114, the second adsorption portion 113 is located at an outer periphery of the charging portion 114, the first charging assembly 140 is disposed on the charging portion 114, multiple second magnetic piece 160 are provided, and the multiple second magnetic pieces 160 are dispersedly disposed on the second adsorption portion 113. The second magnetic pieces 160 are disposed to be in one-to-one correspondence with the first magnetic pieces 130 to ensure a sufficient adsorption force. On the other hand, the second magnetic pieces 160 can be adsorbed to the second adsorption pieces 240 of the charging dock 200 to ensure that the wireless power apparatus 100 is securely connected to the charging dock 200 in the power supply process. The multiple second magnetic pieces 160 are uniformly dispersed around the power supply portion 112, which allows simpler alignment of the equipment body 310 with the charging dock 200. After roughly aligning the equipment body 310 with the charging dock 200, alignment of the equipment body 310 with the wireless power apparatus 100 can be achieved through the adsorption of the multiple first magnetic pieces 160 and the second adsorption pieces 240 of the charging dock 200.
In this embodiment, four second magnetic pieces 160 and four second adsorption pieces 240 are provided, and an included angle between any two adjacent second magnetic pieces 160 is 90 degrees, and an included angle between any two adjacent second adsorption pieces 240 is 90 degrees.
The wireless power apparatus 100 includes multiple prompting assemblies for prompting at least one of a first state of charging the first battery 120, a second state of charging the equipment body 310, or a third state of a charge of the wireless power apparatus 100. In this embodiment, the prompting assembly includes an indicator light, and indicates the three states through on and off of the indicator light. A specific indication manner is not limited herein. The power apparatus 100 is provided with an operation portion 170, and the operation portion 170 can be used for controlling the on/off state of the indicator light or other functions, and particularly, the prompting assembly can be controlled by the operation portion 170 to prompt the third state.
In this embodiment, the capacity, size and other performance parameters of the first battery 120 can be set according to requirements, which are not limited herein. A charging process of the wireless power apparatus 100 is compatible with a QI protocol and an Magsafe ecological chain. The wireless power apparatus 100 can achieve the waterproof and dustproof of IP 67.
This embodiment further provides a charging dock 200 configured to charge the wireless power apparatus 100 described above. The charging dock 200 includes a base 210, a power line 220 and a second charging assembly 230, where the base 210 is provided with a second adsorption piece 240 capable of being adsorbed to the second magnetic piece 160, one end of the power line 220 is electrically connected to a power grid, the other end of the power line 220 is electrically connected to the second charging assembly 230 disposed on the base 210, and the second charging assembly 230 can charge the first battery 120 in cooperation with the first charging assembly 140. Specifically, the second charging assembly 230 includes a positive charging terminal 231 and a negative charging terminal 232, where the positive charging terminal 231 and the negative charging terminal 232 are connected to the positive terminal 141 and the negative terminal 142, respectively.
To avoid the wireless power apparatus 100 from being separated from the charging dock 200 due to a lateral force in the power supply process, in this embodiment, the base 210 is provided with a limiting position piece located around the wireless power apparatus 100. Specifically, the limiting position piece is an annular structure surrounding the wireless power apparatus 100.
In another embodiment, a surface of the charging dock 200 that abuts the wireless power apparatus 100 includes a power portion 211 and an abutment portion 212. The abutment portion 212 is disposed around an outer periphery of the power portion 211, the abutment portion 212 has a structure of a conical surface, which is bent downward, and a central vertical line of the power portion 211 passes through a ball center of the abutment portion 212. A lower end surface of the housing 110 is shaped to fit the charging dock 200. This arrangement allows the wireless power apparatus 100 to tend to move away from the equipment body 310 when a lateral force perpendicular to the central vertical line is applied to the wireless power supply apparatus 100, and an adsorption force between the second magnetic member 160 and the second attraction member 240 needs to be overcome, improving the firmness of the connection between the wireless power apparatus 100 and the charging dock 200. In other implementations of this embodiment, the abutment portion 212 may have a structure of a conical surface, and the center vertical line L1 of the power portion 211 passes through the vertex O of the abutment portion 212. Of course, for ease of manufacturing, the conical surface of the abutment portion 212 may have a certain curvature to facilitate a smooth transition with the planar power portion 211 and a circumferential side wall of the base 210.
In this embodiment, the charging dock 200 is provided with multiple connected bases 210, each base 210 is provided with one charging stand, and each charging stand has a power portion 211 and an abutment portion 212. Each charging stand has a power light 250 to indicate whether a charging is normal.
This embodiment further provides an electronic equipment 300. The electronic equipment 300 includes an equipment body 310 and the wireless power apparatus 100 in the embodiment one, the equipment body 310 is provided with a first adsorption piece 320 capable of being adsorbed to the first magnetic piece 130, the first battery 120 is capable of powering the equipment body 310 through the wireless power supply assembly 150. With such configuration, the equipment body 310 and the wireless power apparatus 100 may be a split structure for ease of portability, and the equipment body 310 may not be provided with a battery, which reduces the cost while reducing the mass. In this embodiment, the equipment body 310 may be a communication device, a lighting device, a cooker, a fan, or the like, where the communication device may be a mobile phone, which is not limited herein.
In camping, the lighting device, the fan or the like is difficult to hang in a proper place in a tent, and thus is inconvenient to use. In this embodiment, since the equipment body 310 and the wireless power apparatus 100 may be the split structure, so that the wireless power apparatus 100 can be placed outside the tent and the equipment body 310 is placed inside the tent to effectively secure the equipment body 310 at any location upon camping out, in this embodiment, the equipment body 310 may be a device such as a lighting device, a screen, or a fan, which is not limited herein.
In an embodiment, wireless receiving coils 330 mounted on the different equipment bodies 310 are the same, and annular adsorption pieces mounted on the different equipment bodies 310 are the same. In another embodiment, wireless receiving coils 330 mounted on different equipment bodies 310 are the same and layouts of the first adsorption pieces 320 mounted on the different equipment bodies 310 are the same. The above arrangement facilitates the layout of the ecological chain.
Of course, in other embodiments, the equipment body 310 may also be provided with the battery. Specifically, if the equipment body 310 includes a stand, and a second battery and an electronic device disposed on the stand, the second battery is configured to power the electronic device, the first battery 120 is capable of powering the second battery through the wireless power supply assembly 150 and/or directly powering the electronic device. The lighting device is used as an example, in an embodiment, the lighting device includes a stand, a second battery and a light bulb electrically connected to the second battery, where the second battery and the light bulb are both disposed on the stand, the light bulb may be defined as the electronic device, and the light bulb may be lit when the first battery 120 powers the light bulb. In a second embodiment, when the first battery 120 powers the second battery and the light bulb simultaneously, the light bulb may be lit during charging of the second battery. In a third embodiment, the light bulb may or may not be lit when the second battery powers the first battery 120.
In this embodiment, the wireless power apparatus 100 may carry the equipment body 310. The arrangement enables the equipment body 310 to use the wireless power apparatus 100 as the base 210, thereby reducing the footprint.
Obviously, the above embodiments of the present disclosure are merely examples for clearly illustrating the present disclosure and are not intended to limit the embodiments of the present disclosure.
