[0035] The purpose of the present application is to provide a wireless charger fixing device and a wireless charger to solve the problem of unstable fixation of internal components of the existing wireless charger.

[0036] The following will be described with reference to the drawings.

[0037] Please refer to Figures 3 to 6 The present application provides a wireless charger, which comprises a wireless charger fixing device, a main board assembly 310 and a secondary board assembly 320, the main board assembly 310 and the secondary board assembly 320 are in communication connection, and the wireless charger fixing device is used to fix the main board assembly 310 and the secondary board assembly 320. In one example, the main board assembly 310 comprises a main PCB board, on which a main circuit module of the wireless charger is arranged; the secondary board assembly 320 comprises a secondary PCB board, which is mainly used for signal switching and assisting in fixing the main PCB board. The main board assembly 310 and the secondary board assembly 320 are in communication connection to realize signal transmission.

[0038] Please refer toFigure 3 This illustrates an example of a motherboard assembly 310, which has a front side ( Figure 3 The observer-facing side) and the opposite side ( Figure 3 (The back of the image). Please refer to... Figure 4 This illustrates an example of a sub-panel assembly 320, which has a front side ( Figure 4 The observer-facing side) and the opposite side ( Figure 4 The back of the motherboard assembly 310. Figure 3 The lower side of the main board assembly 310 is used for connection with the sub-board assembly 320. For ease of description, the side of the main board assembly 310 connected to the sub-board assembly 320 is referred to as the connecting edge 311, and the other side opposite the connecting edge 311 is referred to as the free edge. The main board assembly 310 includes multiple pads 312 arranged along the connecting edge 311. The multiple pads 312 can be arranged adjacent to each other in a shape similar to a stamp hole. Correspondingly, the front side of the sub-board assembly 320 has circuit connection pins 321 adapted to the pads 312. After the pads 312 and the circuit connection pins 321 are attached and soldered together, they serve both a positioning function and an electrical connection function, and the connection is firm and reliable.

[0039] Furthermore, the wireless charger also includes components such as a coil 330 and a battery 340, with the coil 330 located on the reverse side of the sub-board assembly 320. Figure 6 (Lower side in the middle), preferably, the winding axis of coil 330 is perpendicular to sub-plate assembly 320. Battery 340 is used to provide power to mainboard assembly 310.

[0040] When the extension direction of the main board assembly 310 is perpendicular to the winding axis of the coil 330 (i.e., the main board assembly 310 is parallel to the sub-board assembly 320), the main board assembly 310 will be subject to electromagnetic interference from the coil 330. Conversely, when the extension direction of the main board assembly 310 is parallel to the winding axis of the coil 330 (i.e., the main board assembly 310 is perpendicular to the sub-board assembly 320), the space occupied by the main board assembly 310 and the sub-board assembly 320 will increase significantly, which is detrimental to reducing the size of the wireless charger. Therefore, preferably, the extension direction of the main board assembly 310 is angled to the extension direction of the sub-board assembly 320. This angle can be selected between 0° and 90° depending on the actual situation, in order to reduce the interference received by the main board assembly 310 while reducing the spatial volume of the main board assembly 310 and the sub-board assembly 320. More preferably, the angle between the extension direction of the main board assembly 310 and the extension direction of the sub-board assembly 320 is preferably between 30° and 60° to achieve a balance between reducing interference and reducing volume. For ease of description, the extension direction of the motherboard assembly 310 will be referred to as the first direction, and the extension direction of the sub-board assembly 320 will be referred to as the second direction.

[0041] Further, in order to make full use of the space of the angle region formed by the main plate assembly 310 and the sub plate assembly 320, the battery 340 can be inclined to extend into the angle region, so as to further reduce the volume of the wireless charger; in addition, the angle region can further stabilize the battery 340.

[0042] Please refer to Figures 1 to 6 Based on the above research and analysis, in order to adapt to the main plate assembly 310 and the sub plate assembly 320, the embodiment of the present application provides a wireless charger fixing device, which comprises a shell structure 100; the shell structure 100 comprises a first limiting assembly 210 and a second limiting assembly 220, the first limiting assembly 210 is used for supporting and positioning the main plate assembly 310 of the wireless charger; the second limiting assembly 220 is used for supporting and positioning the sub plate assembly 320 of the wireless charger; wherein the first limiting assembly 210 is used for limiting the main plate assembly 310 to extend along a first direction; the second limiting assembly 220 is used for limiting the sub plate assembly 320 to extend along a second direction; the first direction and the second direction are arranged at an angle. Optionally, the included angle between the first direction and the second direction is between 0° and 90°, preferably between 30° and 60°. In this way, the shell structure 100 limits the main plate assembly 310 and the sub plate assembly 320 to be arranged at an angle through the first limiting assembly 210 and the second limiting assembly 220, and after the main plate assembly 310 and the sub plate assembly 320 are connected, the stability of the main plate assembly 310 and the sub plate assembly 320 in the shell structure 100 and the reliability of the electrical connection structure can be ensured, the structure is simple, easy to implement, and further reduces the volume, facilitating carrying and use.

[0043] Optionally, the shell structure 100 comprises a first shell 110 and a second shell 120 which are detachably connected. In order to facilitate assembly, the shell structure 100 is divided into a first shell 110 and a second shell 120 which are detachably connected, and after the first shell 110 and the second shell 120 are assembled, an accommodating cavity is formed inside, in which the main plate assembly 310, the sub plate assembly 320, the coil 330 and the battery 340 and the like are accommodated. The connection mode of the first shell 110 and the second shell 120 can be the commonly used mode in the art such as buckle, screw, adhesion, ultrasonic welding, and preferably ultrasonic welding, which can meet the dustproof and waterproof performance requirements of IP65.

[0044] Preferably, as Figure 1 and Figure 6As shown, the first limiting component 210 includes a main board support 211, and the second limiting component 220 includes a sub board support 221. The main board support 211 and the sub board support 221 are respectively connected with the first shell 110. The main board support 211 has a main board support surface extending along the first direction, which is used to support the bottom surface of the main board assembly 310. The sub board support 221 has a sub board support surface extending along the second direction, which is used to support the bottom surface of the sub board assembly 320. In some embodiments, the main board support 211 and the sub board support 221 can exist simultaneously. In other embodiments, the main board support 211 and the sub board support 221 can be selectively arranged.

[0045] In Figure 1 In the exemplary embodiment shown, when the first shell 110 is placed in a horizontal direction, the second direction also extends along the horizontal direction, and the first direction is inclined relative to the horizontal direction. After assembly, as shown in Figure 6 , the back surface of the main board assembly 310 is placed on the main board support surface of the main board support 211, and the back surface of the sub board assembly 320 is placed on the sub board support surface of the sub board support 221. The main board support surface (i.e. the top surface of the main board support 211 in Figure 1 ) is an inclined surface, which can support the back surface of the main board assembly 310 to extend along the first direction. The sub board support surface (i.e. the top surface of the sub board support 221 in Figure 1 ) is a horizontal surface, which can support the back surface of the sub board assembly 320 to extend along the second direction, i.e. horizontally. In some embodiments, the main board support 211 and the sub board support 221 can be integrally formed with the first shell 110, for example, by molding, injection molding or 3D printing. In other embodiments, the main board support 211 and the sub board support 221 can be independently formed and then connected with the first shell 110, for example, by secondary injection molding, welding or bonding.

[0046] Further, the main board support 211 also has a main board stop surface 217 extending along a direction perpendicular to the first direction, which is used to abut against the connecting edge 311 of the main board assembly 310. In an exemplary embodiment, the main board stop surface 217 intersects with the main board support surface to form a stop notch with an angle of 90°, which is used to accommodate the connecting edge 311. The main board stop surface 217 abuts against the connecting edge 311, thereby limiting the movement of the main board assembly 310 towards the connecting edge 311.

[0047] Preferably, as Figure 2As shown, the first limiting component 210 further comprises a main plate pressing member 212, and the second limiting component 220 comprises a sub plate pressing member 222. The main plate pressing member 212 and the sub plate pressing member 222 are respectively connected with the second housing 120. The main plate pressing member 212 has a main plate pressing surface extending along the first direction, which is used to abut against the front surface of the main plate assembly 310. The main plate pressing surface is oppositely arranged with the main plate supporting surface for clamping the main plate assembly 310. The sub plate pressing member 222 has a sub plate pressing surface extending along the second direction, which is used to abut against the front surface of the sub plate assembly 320. The sub plate pressing surface is oppositely arranged with the sub plate supporting surface for clamping the sub plate assembly 320. In some embodiments, the main plate pressing member 212 and the sub plate pressing member 222 can exist simultaneously. In other embodiments, the main plate pressing member 212 and the sub plate pressing member 222 can be selectively arranged.

[0048] Please continue to refer to Figure 3 In an exemplary embodiment, the main plate assembly 310 further comprises a pressing connecting portion 313 arranged on the front surface of the main plate assembly 310, which is used to abut against the main plate pressing member 212 correspondingly. Please refer to Figure 6 After the first housing 110 and the second housing 120 are assembled and connected, the main plate pressing surface is opposite to the main plate supporting surface, and the main plate pressing member 212 can cooperate with the main plate supporting member 211 to clamp the main plate assembly 310. The sub plate pressing surface is opposite to the sub plate supporting surface, and the sub plate pressing member 222 can cooperate with the sub plate supporting member 221 to clamp the sub plate assembly 320. In some embodiments, the main plate pressing member 212 or the sub plate pressing member 222 can be integrally formed with the second housing 120. In other embodiments, the main plate pressing member 212 or the sub plate pressing member 222 can be independently formed and then connected with the second housing 120, for example, by using secondary injection molding.

[0049] Preferably, the main board pressing member 212 is at least partially elastic, and / or the sub-board pressing member 222 is at least partially elastic. In an alternative embodiment, the main board pressing member 212 is entirely elastic, and the material of the main board pressing member 212 is a flexible material with elasticity, such as elastic plastic TPE. In some other embodiments, the main board pressing member 212 is made of elastic material for the part of the main board pressing member 212 that constitutes the main board pressing surface, and the rest of the main board pressing member 212 can be made of a material without elasticity. The sub-board pressing member 222 can be arranged in the same way as the main board pressing member 212. Considering that the main board assembly 310 and the sub-board assembly 320 are rigidly connected, the part of the main board pressing member 212 and the sub-board pressing member 222 that constitutes the pressing surface is elastic, so that the main board pressing member 212 and the sub-board pressing member 222 can be deformed when they are pressed against the main board assembly 310 and the sub-board assembly 320, thereby avoiding exerting stress on the welding points of the main board assembly 310 and the sub-board assembly 320 and affecting the connection reliability of the main board assembly 310 and the sub-board assembly 320.

[0050] Preferably, please refer to Figure 2 and Figure 6 The first limiting assembly 210 further comprises a main board limiting slot 213, which is connected with the second housing 120 and used for accommodating the free edge of the main board assembly 310. The main board supporting member 211 and the main board pressing member 212 are mainly used for limiting the displacement of the main board assembly 310 in the direction perpendicular to the first direction, and the main board limiting slot 213 is used for limiting the displacement of the main board assembly 310 in the direction away from the connecting edge 311 in the first direction. In some embodiments, the main board limiting slot 213 can be integrally formed with the second housing 120, and in some other embodiments, the main board limiting slot 213 can be independently formed and then connected with the second housing 120, for example, by using secondary injection molding. Preferably, the material of the main board limiting slot 213 is a flexible material with elasticity, such as elastic plastic TPE.

[0051] Further, the main board limiting slot 213 has a first limiting surface 214 and a second limiting surface 215, the extension direction of the first limiting surface 214 is perpendicular to the second direction, and the extension direction of the second limiting surface 215 is parallel to the first direction. In Figure 2 and Figure 6In the shown example, the second housing 120 is configured to be assembled with the first housing 110 along a direction perpendicular to the second direction, the first limiting surface 214 is configured to be perpendicular to the horizontal direction, and the second limiting surface 215 is configured to be inclined to the horizontal direction. The first limiting surface 214 is perpendicular to the second direction, and thus does not hinder the mainboard assembly 310 when the second housing 120 is assembled with the first housing 110, facilitating the assembly of the second housing 120 with the first housing 110. After the second housing 120 is assembled with the first housing 110, the first limiting surface 214 and the second limiting surface 215 together form a mainboard limiting groove 213, which can limit the side of the mainboard assembly 310 away from the connecting edge 311, and prevent the mainboard assembly 310 from moving away from the connecting edge 311 along the first direction.

[0052] Preferably, referring to Figure 2 , the first limiting assembly 210 further comprises a mainboard positioning member 216, which is connected with the second housing 120 and is configured to limit the position of the mainboard assembly 310 along a direction parallel to the connecting edge 311. Optionally, the mainboard positioning member 216 comprises two sub-positioning members arranged oppositely, and the distance between the two sub-positioning members is adapted to the width of the mainboard assembly 310 along the direction parallel to the connecting edge 311. The mainboard assembly 310 can be accommodated between the two sub-positioning members and abut against the two sub-positioning members at the same time. Thus, the mainboard positioning member 216 limits the position of the mainboard assembly 310 along the direction parallel to the connecting edge 311. In some embodiments, the mainboard positioning member 216 can be integrally formed with the second housing 120, and in other embodiments, the mainboard positioning member 216 can be formed independently and then connected with the second housing 120.

[0053] Preferably, referring to Figure 5 , and combining Figure 1 , the second limiting assembly 220 comprises a subboard fixing member 223 configured to fix the subboard assembly 320, and the subboard fixing member 223 is detachably connected with the first housing 110. In an alternative example, the subboard fixing member 223 is a screw, and the specification of the screw can be M2. The first housing 110 has a screw hole 111 adapted to the screw, and correspondingly, the subboard assembly 320 has a through hole 322, and the screw is screwed into the screw hole 111 after passing through the through hole 322, so that the subboard assembly 320 is fixed on the first housing 110. It should be understood that the screw described above is only an example of the subboard fixing member 223, and is not a limitation on the subboard fixing member 223. In other embodiments, the subboard fixing member 223 can also be other structural components, such as buckles, rivets or limiting columns, and the present embodiment is not limited thereto.

[0054] Preferably, referring to Figure 6The second limiting assembly 220 comprises a sub-board positioning member 224 for the side of the sub-board assembly 320. The sub-board positioning member 224 is connected with the first housing 110 or the second housing 120, and is used to limit the position of the sub-board assembly 320 in the second direction by abutting against the side of the sub-board assembly 320. Optionally, the sub-board positioning member 224 comprises at least two sub-positioning surfaces 2241, and the sub-board assembly 320 has abutting surfaces 323 corresponding to the sub-positioning surfaces 2241 on the outer periphery thereof. The sub-positioning surfaces 2241 are arranged at positions corresponding to the abutting surfaces 323. The sub-board assembly 320 can be accommodated between the at least two sub-positioning surfaces 2241, and the abutting surfaces 323 abut against the sub-positioning surfaces 2241 at the same time. Thus, the sub-board positioning member 224 limits the position of the sub-board assembly 320 in the second direction. Preferably, the at least two sub-positioning surfaces 2241 are arranged at an angle to limit the movement of the sub-board assembly 320 in different directions. Please refer to Figure 1 In an exemplary embodiment, the sub-board positioning member 224 is integrated with the main-board supporting member 211, and the sub-board positioning member 224 comprises four sub-positioning surfaces 2241. The two side walls of each main-board supporting member 211 are configured as two sub-positioning surfaces 2241 of the sub-board positioning member 224. Of course, in other embodiments, the sub-board positioning member 224 can be arranged independently of the main-board supporting member 211. Further, the sub-board positioning member 224 can not only limit the position of the sub-board assembly 320, but also facilitate the guiding during the assembly of the sub-board assembly 320.

[0055] In summary, in the wireless charger fixing device and the wireless charger provided by the present application, the wireless charger fixing device comprises a housing structure, and the housing structure comprises a first limiting assembly and a second limiting assembly. The first limiting assembly is used to support and position a main-board assembly of the wireless charger. The second limiting assembly is used to support and position a sub-board assembly of the wireless charger. The first limiting assembly is used to limit the extension of the main-board assembly in a first direction. The second limiting assembly is used to limit the extension of the sub-board assembly in a second direction. The first direction is arranged at an angle to the second direction. In this way, the housing structure limits the main-board assembly and the sub-board assembly to be arranged at an angle by the first limiting assembly and the second limiting assembly. After the main-board assembly and the sub-board assembly are connected, the stability of the main-board assembly and the sub-board assembly in the housing structure and the reliability of the electrical connection structure can be ensured. The structure is simple and easy to implement, and the volume is further reduced, facilitating the carrying and use.

[0056] It should be noted that the above embodiments can be combined with each other.
