DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In the present application, the terms "upper", "lower", "left", "right", "inner", "outer", "vertical", "horizontal", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0040] In addition, in addition to indicating the orientation or positional relationship, the above-mentioned partial terms may also be used to indicate other meanings, for example, the term "upper" may also be used to indicate a certain dependent relationship or connection relationship in some cases. For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific situation.

[0041] In addition, the terms "provided", "provided with", "connected", "connected to" should be broadly understood. For example, it can be a fixed connection, a detachable connection, or a monolithic structure; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific situation.

Unless otherwise stated, the meaning of "multiple" is two or more.

[0043] With the increasing demand for convenience and immediacy of terminal equipment power supply, the contact type power transmission method cannot meet the actual needs, and more and more terminal equipment has begun to use wireless charging. Wireless charging requires using a wireless charger to charge the terminal equipment. The wireless charger is a device that uses the principle of electromagnetic induction to charge. Its principle is similar to that of a transformer. By placing a coil at the sending end and the receiving end, the sending end coil sends electromagnetic signals to the outside under the action of power, and the receiving end coil receives the electromagnetic signals and converts them into electric current, thereby achieving the purpose of wireless charging.

[0044] In the related art, in order to meet the demand of charging multiple different types of terminal equipment at the same time, such as mobile phones, smart watches, Bluetooth earphones, etc., more and more three-in-one wireless charger products of multiple types have appeared, which can help to charge three types of terminal equipment at the same time and improve the charging efficiency.

[0045] Since the coil position in the wireless charger in the related art is fixed, but the terminal device to be charged is different in size and shape, in the charging process, the coil of the terminal device and the coil in the wireless charger are not aligned, which results in low charging efficiency, thereby causing energy waste.

[0046] Therefore, the embodiment of the present application provides a wireless charging device, which comprises a base and a first wireless charging module, the first wireless charging module is arranged on the base, the first wireless charging module is configured to charge a first terminal device, and the first wireless charging module comprises a first shell and a first coil assembly. The first coil assembly is slidably arranged in the first shell, and the first coil assembly can slide relative to the first shell, which is helpful to flexibly change the position of the first coil assembly relative to the first shell, thereby on the one hand, it is helpful to accurately align the first coil assembly with the coil in the first terminal device by adjusting the position of the first coil assembly, and then the wireless charging device can adapt to different sizes of the first terminal device. On the other hand, the alignment of the first coil assembly and the coil in the first terminal device is helpful to improve the charging efficiency of the wireless charging device on the first terminal device. In addition, the wireless charging device is also provided with a second wireless charging module to wirelessly charge a second terminal device, and a third wireless charging module to charge a third terminal device, at least two of the first terminal device, the second terminal device and the third terminal device are different terminal devices, which is helpful to make the wireless charging device can simultaneously wirelessly charge different types of terminal devices, thereby helping to improve the charging efficiency of the wireless charging device.

[0047] The technical solutions of the present application will be further described below in combination with the embodiments and the drawings.

[0048] Please refer to Figures 1 to 3 , Figure 1 is a structural schematic view of a perspective view of the wireless charging device disclosed by the embodiment of the present application, Figure 2 is a structural schematic view of another perspective view of the wireless charging device disclosed by the embodiment of the present application, Figure 3is a structural schematic view of a first wireless charging module (omitted part of structure) disclosed by embodiments of the present application. The wireless charging device 100 comprises a base 1 and a first wireless charging module 2 arranged on the base 1, the first wireless charging module 2 comprises a first shell 21 and a first coil assembly 211 slidably arranged in the first shell 21, and the first coil assembly 211 is configured to supply wireless charging for a first terminal device. At the same time, since the first coil assembly 211 is slidably arranged in the first shell 21, the first coil assembly 211 can slide relative to the first shell 21, so as to change the position of the first coil assembly 211 relative to the first shell 21. This arrangement helps to align the coil assembly in the first terminal device of different sizes by adjusting the position of the first coil assembly 211 in the first shell 21, which helps to improve the charging efficiency of the first wireless charging module 2 for the first terminal device, and helps to improve the size inclusiveness of the first wireless charging module 2 for the first terminal device. The arrangement of the first shell 21 helps to protect the first coil assembly 211 in the first shell 21, thereby helping to improve the service life of the first coil assembly 211.

[0049] It can be understood that the first terminal device can include but is not limited to smart watches, smart bracelets and the like. Taking a smart watch as an example, considering that the sizes of smart watches of different brands may be different, the positions of the coil assemblies in the smart watches are also different. By slidably arranging the first coil assembly 211 in the first shell 21, the first coil assembly 211 can slide relative to the first shell 21, so as to change the position of the first coil assembly 211 relative to the first shell 21, which helps to align the first coil assembly 211 with the coil assembly in the smart watch of different sizes, thereby helping to improve the adaptability of the first wireless charging module 2 for the first terminal device of different sizes.

[0050] It can be understood that the material of the first shell 21 can be plastic or polycarbonate fireproof material, etc. The plastic is low in price and light in weight, which helps to improve the economy and portability of the first shell 21. The polycarbonate fireproof material has good fireproof performance, which helps to ensure the safety of the first shell 21 during use. This embodiment does not make specific limitation.

[0051] It can be understood that the above-mentioned first coil assembly 211 can slide relative to the first shell 21 in various embodiments. In one example, the first coil assembly 211 can slide relative to the first shell 21 in a manual sliding manner. The first shell 21 is provided with an operating member 21122 connected to the first coil assembly 211, and the first coil assembly 211 can be driven to slide relative to the first shell 21 by manually moving the operating member 21122. This manual sliding arrangement helps to improve the structural simplicity of the first coil assembly 211 that can slide relative to the first shell 21 and the economy of the wireless charging device 100.

[0052] In another example, the first coil assembly 211 can slide relative to the first shell 21 in an electric sliding manner. The first shell 21 is externally provided with a control member including a driving member and a control button, the driving member is connected to the first coil assembly 211, and the control button is used to control the start of the driving member. The driving member can drive the first coil assembly 211 to slide relative to the first shell 21 by controlling the control button. This electric sliding arrangement helps to improve the operation convenience and accuracy of the first coil assembly 211 that can slide relative to the first shell 21.

[0053] The present embodiment will be described below with the first coil assembly 211 sliding relative to the first shell 21 in a manual sliding manner as an example.

[0054] In some embodiments, please refer to Figure 3 and Figure 4 , Figure 4 is an exploded view of the first wireless charging module structure disclosed in the present embodiment. The first shell 21 is provided with a sliding groove 21311, and the first coil assembly 211 includes a coil body 2111 and a bracket 2112. The coil body 2111 is connected to the bracket 2112, and the bracket 2112 is slidably arranged on the first shell 21 and can slide relative to the sliding groove 21311 to drive the coil body 2111 to slide relative to the sliding groove 21311. By arranging the coil body 2111 on the bracket 2112, the bracket 2112 can be slid relative to the sliding groove 21311, and the coil body 2111 can be slid relative to the sliding groove 21311. On the other hand, the coil body 2111 and the sliding groove 21311 are connected through the bracket 2112, which helps to ensure that the coil body 2111 will not be damaged by friction with the sliding groove 21311 during sliding relative to the sliding groove 21311.

[0055] It can be understood that the above-mentioned sliding groove 21311 can be arranged on any side wall of the first shell 21, which is not limited in the present embodiment.

[0056] Alternatively, please refer to Figure 4The two sliding grooves 21311 are arranged along the height direction of the first shell 21 and are in the form of long strip-shaped sliding grooves 21311 extending along the height direction of the first shell 21, so that the bracket 2112 can slide along the height direction of the first shell 21 relative to the sliding grooves 21311. Compared with the mode of arranging only one single sliding groove 21311, the arrangement of two spaced sliding grooves 21311 along the sliding direction of the bracket 2112 helps to transmit the asymmetric pressure received by the bracket 2112, and further helps to make the stress of the bracket 2112 more dispersed and uniform.

[0057] Referring to the drawings, the coil body 2111 is formed by winding a wire. The wire can be, but is not limited to, a conductive material such as a copper wire or an aluminum wire, and the winding shape of the wire can be, but is not limited to, a circular shape or a square shape. The material and the winding shape of the wire are not limited in the present embodiment.

[0058] In some embodiments, referring to Figure 3 and 4 , the bracket 2112 includes a mounting member 21121 and an operating member 21122. The mounting member 21121 is arranged inside the first shell 21 and is connected with the coil body 2111. The operating member 21122 is connected with the mounting member 21121 and at least partially extends out of the sliding groove 21311. The operating member 21122 can slide relative to the sliding groove 21311 to drive the mounting member 21121 and the coil body 2111 to slide relative to the sliding groove 21311. By arranging the mounting member 21121 and the operating member 21122 in a split manner, the mounting member 21121 is arranged inside the first shell 21 and is connected with the coil body 2111, and the operating member 21122 at least partially extends out of the sliding groove 21311, which helps the user to operate the part of the operating member 21122 extending out of the sliding groove 21311, so that the operating member 21122 can slide relative to the sliding groove 21311 to drive the mounting member 21121 and the coil body 2111 to slide relative to the sliding groove 21311. Compared with the integral arrangement of the bracket 2112, the split arrangement helps to improve the operation convenience of the bracket 2112 sliding relative to the sliding groove 21311.

[0059] In some embodiments, referring to Figure 3 and Figure 4 , the first shell 21 includes a front shell 212 and a rear shell 213 connected with the front shell 212 to form a mounting cavity 214. The rear shell 213 is provided with the sliding groove 21311 on the side surface away from the front shell 212. The sliding groove 21311 is in communication with the mounting cavity 214, and the mounting member 21121 is arranged on the rear shell 213 and located in the mounting cavity 214.

[0060] To facilitate the adjustment of the sliding position of the mounting member 21121 relative to the sliding groove 21311, the inner side wall of the rear shell 213 is provided with a limiting portion 2132 extending along the height direction of the rear shell 213, and the limiting portion 2132 is formed with a plurality of stops 21321 extending along the extending direction of the limiting portion 2132, any one of the plurality of stops 21321 is configured to be connected with the mounting member 21121 to limit the sliding position of the mounting member 21121 relative to the sliding groove 21311. By providing the limiting portion 2132 extending along the height direction of the rear shell 213, and any one of the stops 21321 of the limiting portion 2132 can be connected with the mounting member 21121, it is helpful to limit the sliding position of the mounting member 21121 relative to the sliding groove 21311 by the limiting portion 2132 when the mounting member 21121 slides relative to the sliding groove 21311, thereby helping to fix the coil body 2111 connected with the mounting member 21121 at the position desired by the user.

[0061] Optionally, referring to Figure 3 and Figure 4 , the limiting portion 2132 can be integrally provided with the rear shell 213, that is, a strip-shaped structure is directly protruded on the rear shell 213 to form the limiting portion 2132. Alternatively, the limiting portion 2132 can also be separately provided with the rear shell 213. For example, the limiting portion 2132 is in a long strip shape extending along the height direction of the rear shell 213, and the limiting portion 2132 is provided with protrusions and recesses at intervals, the recesses are formed as the stops 21321 for connecting with the mounting member 21121 to limit the sliding position of the mounting member 21121 relative to the sliding groove 21311. Meanwhile, the protrusions on both sides of the recesses serve to limit the connection position of the mounting member 21121, which helps to improve the stability of the connection of the stops 21321 of the limiting portion 2132 with the mounting member 21121.

[0062] In addition to the form of providing a plurality of protrusions and recesses at intervals, the limiting portion 2132 can also be in the form of providing a plurality of limiting grooves on the rear shell 213 at intervals, the limiting grooves can be clamped with the mounting member 21121, which is not specifically limited in the present embodiment.

[0063] Some embodiments, please continue to refer to Figure 3 and Figure 4The first coil assembly 211 further comprises an elastic member 2113 arranged on the outer circumferential side of the mounting member 21121 to protrude relative to the mounting member 21121. The elastic member 2113 is configured to be clamped with any one of the stops 21321 of the limiting portion 2132 to limit the sliding position of the mounting member 21121 relative to the sliding groove 21311. By arranging the elastic member 2113 on the outer circumferential side of the mounting member 21121 to protrude relative to the mounting member 21121, the elastic member 2113 can be clamped with the recess on the limiting portion 2132, thereby achieving the limiting effect. In addition, the elastic member 2113 has a certain elasticity and can restore to the original shape after deformation, thereby helping the elastic member 2113 to move between the multiple stops 21321 of the limiting portion 2132 when the mounting member 21121 slides relative to the sliding groove 21311.

[0064] Optionally, referring to Figure 3 and Figure 4 , the elastic member 2113 can be a V-shaped elastic piece or an elastic block, etc. Taking the V-shaped elastic piece as an example, one end of the V-shaped elastic piece is clamped on the outer circumferential edge of the mounting member 21121, and the other end is used to be clamped with the stop 21321 of the limiting portion 2132 to limit the sliding position of the mounting member 21121 relative to the sliding groove 21311. Taking the elastic block as an example, one end of the elastic block is connected to the outer circumferential side of the mounting member 21121, and the other end is used to be clamped with the stop 21321 of the limiting portion 2132 to limit the sliding position of the mounting member 21121 relative to the sliding groove 21311. The present embodiment does not make specific limitation thereon.

[0065] In some embodiments, referring to Figure 3 and Figure 4 , the rear shell 213 is provided with a limiting portion 2132 on each of the two inner side walls along the length direction thereof, and the two limiting portions 2132 are symmetrically arranged. The outer circumferential side of the corresponding mounting member 21121 is also provided with two symmetrically arranged elastic members 2113. The limiting portion 2132 and the elastic member 2113 are symmetrically arranged in two, so that the elastic members 2113 on both sides of the mounting member 21121 are clamped with the stops 21321 of the corresponding limiting portion 2132. Compared with the arrangement of arranging the limiting portion 2132 and the elastic member 2113 on only one side, this arrangement helps to balance the stress on both sides of the mounting member 21121, thereby helping to improve the limiting effect of the limiting portion 2132 on the mounting member 21121.

[0066] Optionally, referring to Figure 3 and Figure 4The front shell 212 is provided with a placement slot 2121 recessed from the front shell 212 to the rear shell 213, which is configured to place the first terminal device. By providing the placement slot 2121 recessed from the front shell 212 to the rear shell 213 on the surface of the front shell 212, on the one hand, it helps to position the placement position of the first terminal device, indicating the user to place the first terminal device in the placement slot 2121 to charge it wirelessly, on the other hand, it helps to improve the stability of the first terminal device placed on the front shell 212.

[0067] Optionally, as known from the foregoing, the first terminal device can be a smart watch, and based on this, the shape of the placement slot 2121 can generally be adapted to the shape of the smart watch, and in order to adapt to smart watches of different specifications, the size of the placement slot 2121 can be set to be relatively large, so that smart watches of different specifications can be placed in the placement slot 2121, and then by adjusting the position of the first coil assembly 211, the effect of charging smart watches of different specifications can be achieved.

[0068] Please refer to Figure 5 and Figure 5 , in combination with Figure 1 , Figure 3 is Figure 4 the sectional view of A-A. The first coil assembly 211 further comprises a magnet 215 for attracting the first terminal device, which helps to fix the first terminal device on the surface of the front shell 212. In addition, one end of the magnet 215 is arranged adjacent to the placement slot 2121 for attracting the first terminal device to the placement slot 2121, which helps to improve the connection stability between the first terminal device and the placement slot 2121, thereby helping to charge the first terminal device stably.

[0069] Optionally, please refer to Figure 5 and Figure 3 , in combination with Figure 4The mounting member 21121 is provided with a plurality of clamping portions 21121a which are arranged along the edges of the mounting member 21121 and extend towards the front shell 212 along the width direction of the mounting member 21121. The plurality of clamping portions 21121a define a mounting space between them, and the coil body 2111 is mounted in the mounting space and clamped to the clamping portions 21121a. By providing the clamping portions 21121a on the mounting member 21121, the coil body 2111 can be mounted on the mounting member 21121, so that the coil body 2111 can be driven to slide along the sliding groove 21311 by sliding the mounting member 21121 in the sliding groove 21311. In addition, the plurality of clamping portions 21121a arranged along the edges of the mounting member 21121 can better clamp the coil body 2111, thereby improving the connection and fastening of the coil body 2111 and the mounting member 21121.

[0070] For example, considering that the coil body 2111 is mostly wound in a ring shape, the clamping portions 21121a can be four, which are arranged in a ring shape along the center of the mounting member 21121, so that the four clamping portions 21121a form a circular mounting space.
