[0008] Hereinafter, the technical means of the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, but obviously, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative work fall within the scope of protection of the present application.

[0009] After extensive research, the inventors have discovered the following: With the development of science and technology, wireless chargers have emerged that allow users to easily charge their devices. Wireless chargers can be used to charge electronic devices such as mobile phones, earphones, and watches. Wireless chargers may be provided with a structure for restricting the position of the device to be charged in order to maintain stability during the charging process. Currently, in prior art, when restricting the position of a wireless charger, it is difficult to adjust the posture of the device, which negatively impacts the user's experience. To solve this technical problem, the present application provides the following embodiments.

[0010] As shown in FIGS. 1 to 3 , a wireless charging device 1 described in an embodiment of the wireless charging device of the present application includes a wireless charging module 100 and a support mechanism 200. The wireless charging module 100 includes a first case 110, a second case 120, a magnetic attraction assembly 130, and a wireless charging assembly 140. The second case 120 is rotatably connected to the first case 110, and the second case 120 is rotatable along a circumferential direction D1 of the first case 110. The wireless charging assembly 140 is connected to the second case 120 or the first case 110 to charge the device to be charged. The magnetic attraction assembly 130 is connected to the second case 120 or the first case 110, and a charging area 123 corresponding to the wireless charging assembly 140 is formed in the second case 120, and the magnetic attraction assembly 130 uses magnetic force to position the device to be charged in the charging area 123. The support mechanism 200 is connected to the first case 110 and supports the wireless charging module 100 .

[0011] Supporting the wireless charging module 100 with the support mechanism 200 is advantageous in that the wireless charging module 100 maintains a stable posture while supporting the device to be charged. Furthermore, lifting the wireless charging module 100 using the support mechanism 200 creates a gap between the wireless charging module 100 and the device to be charged and the placement surface of the wireless charging device 1, making it easier to rotate the wireless charging module 100 and the device to be charged relative to the first case 110.

[0012] The device to be charged may need to be adjusted during charging. For example, the device to be charged may be a mobile phone, and by rotating the device to be charged relative to first case 110, the orientation of the mobile phone can be adjusted, and the mobile phone can be switched between portrait mode and landscape mode. Also, for example, the device to be charged may be a mobile phone, and by rotating the device to be charged relative to first case 110, a crooked mobile phone can be straightened.

[0013] By arranging second case 120 and first case 110 so that they are rotatably connected, when the user adjusts the attitude of the device to be charged along circumferential direction D1 of first case 110, second case 120 and the device to be charged can rotate synchronously, so that there is no sliding friction between second case 120 and the device to be charged, or the sliding friction between second case 120 and the device to be charged can be reduced, which is advantageous in improving the smoothness of rotation of the device to be charged, making it easier to adjust the attitude of the device to be charged, and improving the feel for the user.

[0014] Preferably, the support mechanism 200 may be electrically connected to the wireless charging module 100 at the first case 110 so that the wireless charging module 100 can be connected to a power source via the support mechanism 200. In some embodiments, the conductive wires 230 may extend from the support mechanism 200 through the first case 110 into the wireless charging module 100 and be electrically connected to the wireless charging assembly 140. When a user adjusts the position of the device to be charged along the circumferential direction D1 of the first case 110, the first case 110 does not need to rotate together with the device to be charged. This reduces the effects of twisting, pulling, pressing, etc. that the conductive wires 230 may experience, thereby reducing the risk of damage to the conductive wires 230.

[0015] Preferably, as shown in FIGS. 1 to 3 , the wireless charging assembly 140 may include a transmitting coil 141 and a magnetic shielding sheet 142. The transmitting coil 141 is for charging the device to be charged, and the magnetic shielding sheet 142 reduces electromagnetic interference and improves charging efficiency. Furthermore, the wireless charging device 1 includes a circuit board assembly 170. In some embodiments, the wireless charging assembly 140 may be mounted on the circuit board assembly 170 and electrically connected to it. The circuit board assembly 170 may control the charging process of the wireless charging assembly 140 for the device to be charged. The circuit board assembly 170 may also assist in heat dissipation of the transmitting coil 141, which is beneficial to reducing the temperature of the transmitting coil 141. The circuit board assembly 170 may include at least one PCB board.

[0016] Furthermore, a heat dissipation gel may be further provided on the circuit board assembly 170 to facilitate heat dissipation of the wireless charging assembly 140.

[0017] Preferably, circuit board assembly 170 is provided within support mechanism 200. For example, support mechanism 200 includes a base 210 and a support rod 220 connected to each other, where first case 110 is connected to support rod 220, and support rod 220 is supported by base 210 to support wireless charging module 100. That is, base 210 supports wireless charging module 100 via support rod 220. Conductive wires 230 may extend from base 210 through support rod 220 into wireless charging module 100. In some embodiments, circuit board assembly 170 may be provided within base 210 to make wireless charging module 100 lighter and thinner and reduce heat generation from wireless charging module 100. In some other embodiments, the circuit board assembly 170 includes a heat dissipation circuit board (not shown) and a control circuit board (not shown), where the control circuit board is arranged in the base 210 and controls the charging process of the wireless charging assembly 140 for the device to be charged, the heat dissipation circuit board is arranged in the wireless charging module 100, the wireless charging assembly 140 is arranged on the heat dissipation circuit board and electrically connected to the heat dissipation circuit board, and the heat dissipation circuit board assists in heat dissipation of the transmitting coil 141 to improve the operating condition of the wireless charging module 100.

[0018] Preferably, the base 210 and the support rod 220 are rotatably connected. The support rod 220 rotates relative to the base 210 to move the first case 110 closer to or farther away from the base 210. In this manner, the support mechanism 200 can be folded, making it easy to store the wireless charging device 1.

[0019] Preferably, the support rod 220 is extendable or foldable, and the height of the support rod 220 can be adjusted by extending or folding, making it easy to store. For example, the support rod 220 includes a first sub-rod body and a second sub-rod body that are rotatably connected, and the first sub-rod body and the second sub-rod body can be rotated relative to each other to fold or extend the support rod 220.

[0020] In some embodiments, the support mechanism 200 is detachably connected to the wireless charging module 100, making it easy to charge the target device after the wireless charging module 100 is removed. Specifically, the support mechanism 200 is detachably connected to the first case 110.

[0021] For example, the support mechanism 200 and the wireless charging module 100 are detachably connected by a buckle or magnetic attraction, or the support mechanism 200 is provided with a clamp that clamps the wireless charging module 100.

[0022] In some embodiments, a battery module (not shown) is provided within the wireless charging module 100, and the battery module can supply power to the device to be charged.

[0023] In some embodiments, the wireless charging module 100 is provided with a charging port (not shown), which is connected to an external power source via a charging line, and can use the external power source to power the device to be charged.

[0024] Furthermore, the charging port is provided on the first case 110, and when the wireless charging module 100 charges the device to be charged, the position of the charging line can be adjusted by rotating the first case 110 relative to the second case 120, making it easier for the wireless charging module 100 to charge the device to be charged in a wider range of situations.

[0025] Preferably, the wireless charging module 100 has a front side 102, a back side 103, and a peripheral side 104 connected between the front side 102 and the back side 103. In some embodiments, the charging port is provided on the peripheral side 104 of the wireless charging module 100. In other embodiments, the charging port is provided on the back side 103 of the wireless charging module 100.

[0026] In some embodiments, the support mechanism 200 is provided with a power supply connector (not shown) that matches the charging port, and when the support mechanism 200 and the wireless charging module 100 are in a connected state, the power supply connector is inserted into the charging port to connect the support mechanism 200 and the wireless charging module 100, and the wireless charging assembly 140 is connected to a power source via the support mechanism 200. In other embodiments, the first case 110 is provided with a first electrical contact (not shown), the wireless charging assembly 140 is electrically connected to the first electrical contact, and the support mechanism 200 is provided with a second electrical contact (not shown) that corresponds to the first electrical contact, and when the support mechanism 200 and the first case 110 are in a connected state, the first electrical contact abuts against the second electrical contact, and the wireless charging assembly 140 is connected to a power source via the support mechanism 200.

[0027] Preferably, as shown in FIGS. 1 to 3 , the support rod 220 includes a main rod 221 and a branch rod 222, where the main rod 221 is connected to the base 210 and the branch rod 222 is connected between the first case 110 and the main rod 221. Furthermore, the number of branch rods 222 may be two or more, and different branch rods 222 may support different wireless chargers, allowing the wireless charging device 1 to charge different devices to be charged (including mobile phones, watches, earphones, etc.). In some embodiments, the wireless chargers supported by the different branch rods 222 may include the wireless charging module 100 and another type of wireless charger. In other embodiments, the wireless chargers supported by the different branch rods 222 are the same or different wireless charging modules 100. For example, the base may be provided with a wireless charger for charging a watch or earphones. For example, the wireless charger supported by the branch rod 222 may charge a watch or earphones.

[0028] In some embodiments, support rod 220 is a single, independent rod, which may be a straight rod, a bent rod, etc. In some embodiments, support rod 220 may include two or more rods arranged side by side. In some embodiments, the cross-sectional shape of support rod 220 is circular or rectangular.

[0029] Preferably, the branch rod 222 is connected between the wireless charging module 100 and the main rod 221. The branch rod 222 has an extendable structure, and the branch rod 222 moves the wireless charging module 100 closer to or farther away from the main rod 221 through extension and retraction. Alternatively, the branch rod 222 is rotatably connected to the main rod 221, and the branch rod 222 moves the wireless charging module 100 closer to or farther away from the main rod 221 through rotation relative to the main rod 221. For example, the branch rod 222 can rotate relative to the main rod 221 to adjust the angle between the branch rod 222 and the main rod 221 between 0° and 180°, and thus the branch rod 222 can be switched between an operating state and a folded state. When the included angle between the branch rod 222 and the main rod 221 is 0°, the branch rod 222 is in a folded state, and when the included angle between the branch rod 222 and the main rod 221 is 45° to 135°, the branch rod 222 is in an operating state. In this way, by changing the shape of the support rod 220, the wireless charging device 1 can be easily folded and stored. The conductive wire 230 may be drilled through the branch rod 222 and the main rod 221, and when the branch rod 222 rotates relative to the main rod 221, the conductive wire 230 can be deformed accordingly.

[0030] Preferably, the branch rod 222 is rotatably connected to the main rod 221 so that the wireless charging module 100 can rotate around the main rod 221 along the circumferential direction of the main rod 221. In this way, the position of the wireless charging module 100 can be easily adjusted, which is advantageous for the wireless charging device 1 to be used in more scenarios. The conductive wire 230 may be drilled through the branch rod 222 and the main rod 221, and when the branch rod 222 rotates relative to the main rod 221, the conductive wire 230 can be deformed accordingly.

[0031] Preferably, the wireless charging module 100 includes a rear-side wireless charging assembly, and the first case 110 is formed with a rear-side charging area corresponding to the rear-side wireless charging assembly, which is connected to the second case 120 or the first case 110 to charge other target devices located in the rear-side charging area. In this way, the wireless charging module 100 can simultaneously charge different target devices, which is advantageous in improving the functionality of the wireless charging module 100.

[0032] Preferably, the wireless charging module 100 includes a rear-side wireless charging assembly and a third case, where the third case has a rear-side charging area corresponding to the rear-side wireless charging assembly. The third case is rotatably connected to the first case 110 and is rotatable along the circumferential direction D1 of the first case 110. The wireless charging assembly is connected to the third case or the first case 110 to charge the device to be charged. The third case and the second case 120 may be connected via the first case 110. In this way, the wireless charging module 100 can simultaneously charge different devices to be charged, which is advantageous in improving the functionality of the wireless charging module 100.

[0033] Preferably, the other device to be charged may be restricted to the rear charging area by using magnetic force from the magnetic attraction assembly 130, or may be attracted to the rear charging area by another magnet. Furthermore, the rear charging area and the charging area 123 are located on opposite sides of the wireless charging module 100.

[0034] Preferably, a battery module (not shown) is provided within the base 210, and the battery module supplies power to the wireless charging device 1.

[0035] 2 and 3, the magnetic attraction assembly 130 preferably includes a plurality of magnets arranged along the circumferential direction D1 of the first case 110. Furthermore, the plurality of magnets are joined together to form a ring structure with a gap, which can be easily installed and meets installation specifications.

[0036] Preferably, the magnetic attraction assembly 130 is disposed around the outer periphery of the wireless charging assembly 140 along the circumferential direction D1 of the first case 110.

[0037] Preferably, as shown in Figures 1 to 3, the accommodating space 160 is formed by being surrounded by the second case 120 and the first case 110, and the magnetic attraction assembly 130 and the wireless charging assembly 140 are both located within the accommodating space 160, and a charging area 123 corresponding to the wireless charging assembly 140 is formed on the side of the second case 120 away from the accommodating space 160.

[0038] In this way, the second case 120 and the first case 110 can protect and shield the magnetic attraction assembly 130 and the wireless charging assembly 140, which is advantageous in improving the structural stability of the wireless charging module 100.

[0039] Preferably, as shown in Figures 1 to 4, the magnetic attraction assembly 130 is connected to the second case 120 and the wireless charging assembly 140 is connected to the first case 110 so that the device to be charged, the second case 120, and the magnetic attraction assembly 130 are all rotatable relative to the first case 110 and the wireless charging assembly 140 along the circumferential direction D1 of the first case 110.

[0040] In this way, when the user adjusts the orientation of the device to be charged along the circumferential direction D1 of the first case 110, the second case 120, the magnetic attraction assembly 130, and the device to be charged can rotate synchronously, which not only eliminates sliding friction between the second case 120 and the device to be charged but also reduces the resistance of the magnetic attraction assembly 130 to the rotation of the device to be charged, improving the smoothness of the rotation of the device to be charged and reducing the force required by the user. Also, in some embodiments, the conductive wire 230 is drilled through the first case 110 and extends from and connected to the wireless charging assembly 140, connecting the wireless charging assembly 140 and the first case 110. This can fix the wireless charging assembly 140 and the first case 110 relative to each other and reduce the effects of twisting, pulling, pressing, etc. on the conductive wire 230, thereby advantageously reducing the risk of damage to the conductive wire 230.

[0041] Furthermore, there is a gap between the wireless charging assembly 140 and the magnetic attraction assembly 130, i.e., the wireless charging assembly 140 and the magnetic attraction assembly 130 are not in contact with each other, thus reducing the resistance of the wireless charging assembly 140 to the rotation of the magnetic attraction assembly 130.

[0042] In some embodiments, wireless charging assembly 140 is removably connected to first case 110. In other embodiments, wireless charging assembly 140 is fixedly connected to first case 110, for example, by adhesive.

[0043] In some embodiments, the magnetic attraction assembly 130 is removably connected to the second case 120. In other embodiments, the magnetic attraction assembly 130 is fixedly connected to the second case 120, for example, by adhesive.

[0044] Preferably, as shown in Figures 1 and 5 to 7, the magnetic attraction assembly 130 and the wireless charging assembly 140 are both connected to the first case 110 so that the device to be charged and the second case 120 can both rotate relative to the first case 110, the wireless charging assembly 140, and the magnetic attraction assembly 130 along the circumferential direction D1 of the first case 110.

[0045] In this way, when the user adjusts the position of the device to be charged along the circumferential direction D1 of the first case 110, there is no sliding friction between the second case 120 and the device to be charged, which is advantageous for improving the smoothness of rotation of the device to be charged, and also for reducing the effects of twisting, pulling, pressing, etc. that the conductor 230 connected to the wireless charging assembly 140 is subjected to, thereby reducing the risk of damage to the conductor 230.

[0046] In some embodiments, both the magnetic attraction assembly 130 and the wireless charging assembly 140 are fixedly connected to the first case 110.

[0047] In some embodiments, during the assembly process, the magnetic attraction assembly 130 and the wireless charging assembly 140 can be pre-fixed using the fixing disk 143, and then the fixing disk 143, the magnetic attraction assembly 130, and the wireless charging assembly 140 can be assembled together to the first case 110, which is advantageous in improving assembly efficiency.

[0048] In some embodiments, both the magnetic attraction assembly 130 and the wireless charging assembly 140 are removably connected to the first case 110.

[0049] Preferably, as shown in Figures 1, 8 to 10, the magnetic attraction assembly 130 and the wireless charging assembly 140 are all connected to the second case 120 so that the device to be charged, the second case 120, the wireless charging assembly 140, and the magnetic attraction assembly 130 are all rotatable relative to the first case 110 along the circumferential direction D1 of the first case 110.

[0050] In this way, when the user adjusts the position of the device to be charged along the circumferential direction D1 of the first case 110, there is no sliding friction between the second case 120 and the device to be charged, which is advantageous for improving the smoothness of rotation of the device to be charged and for reducing the resistance of the magnetic attraction assembly 130 to the rotation of the device to be charged. In addition, by arranging the wireless charging assembly 140 and the device to be charged to rotate synchronously, it is advantageous for improving the stability of the process in which the wireless charging assembly 140 charges the device to be charged.

[0051] Specifically, sliding friction is the frictional force between second case 120 and the supported device when they slide relative to each other, and static friction is the frictional force between second case 120 and the supported device when they are fixed relative to each other. In some embodiments, the magnetic attraction of second case 120 to the device to be charged is strong, or the coefficient of friction between second case 120 and the device to be charged is large, so that when the user adjusts the position of the device to be charged along circumferential direction D1 of first case 110, no sliding friction exists between second case 120 and the device to be charged, i.e., second case 120 and the device to be charged rotate in perfect synchronization. In some other embodiments, the magnetic attraction force of the second case 120 to the device to be charged is weak, or the coefficient of friction between the second case 120 and the device to be charged is small, so that when the user adjusts the position of the device to be charged along the circumferential direction D1 of the first case 110, sliding friction exists between the second case 120 and the device to be charged, i.e., the second case 120 and the device to be charged do not rotate in perfect synchronization.

[0052] In some embodiments, both the magnetic attraction assembly 130 and the wireless charging assembly 140 are fixedly connected to the second case 120.

[0053] In some embodiments, both the magnetic attraction assembly 130 and the wireless charging assembly 140 are removably connected to the second case 120.

[0054] 8, the wireless charging module 100 preferably includes two elastic conductive contacts 122 and two conductive portions 112 that abut against each other, where the two elastic conductive contacts 122 are provided on one of the second case 120 and the first case 110, and the two conductive portions 112 are provided on the other of the second case 120 and the first case 110. The wireless charging assembly 140 is connected to a power source via the two elastic conductive contacts 122 and the two conductive portions 112.

[0055] Specifically, the wireless charging module 100 includes elastic conductive contacts 122 and conductive portions 112 that abut correspondingly and are relatively slidable. The elastic conductive contacts 122 are provided on the second case 120 and electrically connected to the wireless charging assembly 140, and the conductive portions 112 are provided on the first case 110 and electrically connected to the power source via the conductive wires 230, so that the wireless charging assembly 140 is electrically connected to the power source via the elastic conductive contacts 122 and the conductive portions 112. Alternatively, the conductive portions 112 are provided on the second case 120 and electrically connected to the wireless charging assembly 140, and the elastic conductive contacts 122 are provided on the first case 110 and electrically connected to the power source via the conductive wires 230, so that the wireless charging assembly 140 is electrically connected to the power source via the elastic conductive contacts 122 and the conductive portions 112.

[0056] There may be two or more elastic conductive contacts 122 and two or more conductive portions 112, for example, three or four. Two elastic conductive contacts 122 and two conductive portions 112 may abut on each other in a one-to-one correspondence. The area of ​​the conductive portion 112 abutting against the elastic conductive contacts 122 may be larger than the area of ​​the conductive portion 112 abutting against the elastic conductive contacts 122. Therefore, when the second case 120 and the first case 110 rotate relative to each other, the elastic conductive contacts 122 slide against the corresponding conductive portion 112 and do not come off from the corresponding conductive portion 112.

[0057] For example, first case 110 and conductive part 112 are fixed relative to each other, and second case 120 and elastic conductive contact 122 are fixed relative to each other. The power source may be a grid output terminal or a battery module provided within base 210. Conductive wire 230 is drawn from the power source and extends to connect to conductive part 112, and wireless charging assembly 140 is connected to elastic conductive contact 122, thereby connecting wireless charging assembly 140 to the power source.

[0058] By providing the elastic conductive contact 122 and the conductive portion 112 that slide relative to each other in place of part of the conductor 230, it is less likely that the conductor 230 will be twisted and damaged when the second case 120 and the first case 110 rotate relative to each other, and the conductor 230 will not pull the wireless charging assembly 140, thereby preventing the relative rotation between the second case 120 and the first case 110 from being hindered, which is advantageous in extending the service life of the wireless charging device 1 and improving the smoothness of rotation of the device to be charged.

[0059] Preferably, the resilient conductive contacts 122 may be pogo pin connectors.

[0060] Preferably, the conductive portion 112 is a metal foil, such as a copper foil, an aluminum foil, etc. The elastic conductive contact 122 is a pogo pin.

[0061] In some embodiments, the conductive contacts are non-resilient conductive contacts.

[0062] Preferably, as shown in FIG. 8, one of the two conductive portions 112 is annular and is provided so as to surround the other of the two conductive portions 112.

[0063] For example, one of the two conductive portions 112 is annular and the other is circular, and the annular conductive portion 112 surrounds the circular conductive portion 112. Correspondingly, when the second case 120 and the first case 110 rotate relative to each other, the elastic conductive contacts 122 abutting against the annular conductive portion 112 slide along the circumferential direction of the annular conductive portion 112, and the sliding locus surrounds the elastic conductive contacts 122 abutting against the circular conductive portion 112. Furthermore, when the second case 120 and the first case 110 rotate relative to each other, the elastic conductive contacts 122 abutting against the circular conductive portion 112 rotate on their own axes. Also, for example, both of the two conductive portions 112 are annular. Also, for example, both of the two conductive portions 112 are arc-shaped.

[0064] In this way, the second case 120 and the first case 110 can rotate relative to each other multiple times from the entire circumference, which is advantageous in that the two conductive parts 112 have a sufficient distance between them, and also makes the structure of the two conductive parts 112 compact, improving space utilization rate.

[0065] 8, the wireless charging module 100 preferably includes a first plate 121 and a second plate 111 disposed opposite each other, the first plate 121 being disposed in the second case 120 and electrically connected to the wireless charging assembly 140, and the second plate 111 being disposed in the first case 110. Two elastic conductive contacts 122 are disposed on one of the first plate 121 and the second plate 111, and two conductive portions 112 are disposed on the other of the first plate 121 and the second plate 111.

[0066] By providing the elastic conductive contacts 122 and the conductive part 112 on the first plate 121 and the second plate 111 respectively, it is advantageous for assembling the wireless charging module 100, improves the connection stability between the elastic conductive contacts 122 and the conductive part 112, and further improves the connection stability between the wireless charging assembly 140 and the power source.

[0067] For example, the two conductive portions 112 can be printed on the surface of the first plate 121 or the second plate 111.

[0068] Furthermore, the first plate 121 and the second plate 111 may be spaced apart, which is beneficial to the heat dissipation of the wireless charging assembly 140.

[0069] Preferably, the first plate 121 may be the heat dissipation circuit board, the control circuit board, or the circuit board assembly 170. The second plate 111 may be a circuit board, which facilitates connecting the conductive portion 112 or the elastic conductive contact 122 with the conductive wire 230.

[0070] 2 to 4, a bearing 151 is preferably provided between second case 120 and first case 110. Second case 120 and first case 110 rotate relatively via bearing 151.

[0071] By providing bearing 151, it is advantageous to improve the smoothness of the relative rotation between second case 120 and first case 110, and bearing 151 has the advantage of being easy to assemble.

[0072] Preferably, the inner ring of bearing 151 is fitted onto the outside of first case 110, and second case 120 is fitted onto the outside of the outer ring of bearing 151. In this way, it is advantageous to reduce the dimensions of first case 110 and increase the dimensions of second case 120, which, on the one hand, makes it difficult to see first case 110 from the side where wireless charging module 100 attracts the device to be charged due to the shielding provided by second case 120, which is advantageous for improving the aesthetics of the appearance, and, on the other hand, is advantageous for increasing the area of ​​the surface of first case 110 where the device to be charged is placed.

[0073] 2 to 4, the first case 110 preferably includes an inner case 113 and an outer case 114. An accommodating space 160 is formed by being surrounded by the second case 120 and the inner case 113, and the magnetic attraction assembly 130 and the wireless charging assembly 140 are located within the accommodating space 160. The outer case 114 is located on the outer periphery of the inner case 113, and an installation space 115 is formed between the outer case 114 and the inner case 113. A bearing 151 is provided within the installation space 115 and fitted onto the outer periphery of the inner case 113, and the second case 120 extends into the installation space 115 and abuts against the outer ring of the bearing 151.

[0074] By providing the bearing 151 in the mounting space 115, the outer case 114 can shield and protect the bearing 151, which is advantageous for maintaining a stable assembly relationship between the bearing 151, the inner case 113, and the second case 120, improving the structural stability of the wireless charging module 100 and improving the aesthetic appearance of the wireless charging module 100.

[0075] Furthermore, the wireless charging assembly 140 may be attached to the inner case 113, and the inner case 113 may be provided with a heat dissipation space 1131 to facilitate heat dissipation from the wireless charging assembly 140.

[0076] Preferably, both the inner case 113 and the outer case 114 are provided with reinforcing ribs 1132 to increase strength, which is advantageous for making the wall thickness uniform and reducing surface depressions caused by uneven shrinkage during molding.

[0077] Preferably, as shown in FIGS. 2 to 4, the inner case 113 has an attachment step 1162 on its outer periphery, and the bearing 151 may be attached to the attachment step 1162 so that the bearing 151 can be easily attached.

[0078] Preferably, the inner case 113 and the outer case 114 may be fixed together with screws.

[0079] As shown in FIGS. 2 to 4 , the second case 120 preferably includes a top cover 124 and a middle frame 125. The middle frame 125 has an attachment opening (not shown) at one end, through which the magnetic attraction assembly 130 and the wireless charging assembly 140 can be attached, and the top cover 124 closes the attachment opening. The charging area 123 is located outside the top cover 124. The other end of the middle frame 125 can be inserted into the attachment space 115 and abut against the outer ring of the bearing 151. In this manner, the wireless charging module 100 can be easily assembled. In some embodiments, the magnetic attraction assembly 130 may be fixed to the top cover 124. In other embodiments, the fixing disk 143, the magnetic attraction assembly 130, and the wireless charging assembly 140 may all be assembled to the top cover 124.

[0080] Preferably, the top cover 124 and the inner frame 125 are connected by adhesive or by a buckle.

[0081] 1 and 2 to 4, the wireless charging module 100 preferably has a front side 102, a back side 103, and a peripheral side surface 104 connected between the front side 102 and the back side 103, the front side 102 adsorbing the device to be charged, the support mechanism 200 being connected to the first case 110 at the back side 103, and on the outer surface of the wireless charging module 100, a seam 105 between the second case 120 and the first case 110 being located on the back side 103 or the peripheral side surface 104. In other words, on the front side 102 of the wireless charging module 100, the second case 120 shields the first case 110, so that the seam 105 between the second case 120 and the first case 110 can be located on the back side 103 or the peripheral side surface 104.

[0082] The seam 105 between the second case 120 and the first case 110 refers to the seam 105 at the boundary between the second case 120 and the first case 110. For example, on the outer surface of the wireless charging module 100, the seam 105 between the second case 120 and the first case 110 is the seam 105 between the inner frame 125 and the first case 110. Furthermore, on the outer surface of the wireless charging module 100, the seam 105 between the second case 120 and the first case 110 is the seam 105 between the inner frame 125 and the outer case 114.

[0083] 1 and 2, on the outer surface of the wireless charging module 100, the seam 105 between the second case 120 and the first case 110 is located on the peripheral side 104. In some embodiments, as shown in FIGS. 1 and 4, the middle frame 125 has a shielding portion 1251 located on the peripheral side 104, and the shielding portion 1251 shields the first case 110 on the peripheral side 104, so that the seam 105 between the second case 120 and the first case 110 on the outer surface of the wireless charging module 100 can be located on the back side 103.

[0084] In this way, it is advantageous to improve the aesthetic appearance of the wireless charging device 1.

[0085] 5 to 7, a rolling member 152 is preferably provided between second case 120 and first case 110. Second case 120 and first case 110 rotate relatively via rolling member 152.

[0086] Providing rolling members 152 is advantageous in improving the smoothness of relative rotation between second case 120 and first case 110, and rolling members 152 can be characterized by their small volume. For example, rolling members 152 are balls, needle rollers, or cylindrical rollers. There may be a plurality of rolling members 152, and the plurality of rolling members 152 may be distributed at intervals in the circumferential direction D1 of first case 110, or may be distributed continuously.

[0087] In some embodiments, the rolling members 152 are located between the top cover 124 and the first case 110. In other embodiments, the rolling members 152 are located between the inner frame 125 and the first case 110.

[0088] In some embodiments, one of the second case 120 and the first case 110 has a groove (not shown) formed therein to accommodate the rolling member 152, and the opening direction of the groove is parallel to or perpendicular to the axial direction in which the second case 120 rotates relative to the first case 110.

[0089] In some embodiments, the bearing 151 and the rolling member 152 may not be provided between the second case 120 and the first case 110 .

[0090] 1, 2, and 7 to 9, first case 110 is preferably provided with stopper surfaces 116 distributed along circumferential direction D1 of first case 110, and stopper surfaces 116 stop second case 120 and restrict second case 120 from separating from first case 110. Stopper surfaces 116 are distributed at intervals or continuously along circumferential direction D1 of first case 110.

[0091] Specifically, the stopper surface 116 restricts the second case 120 from separating from the first case 110 along the extension direction of the axis along which the second case 120 rotates relative to the first case 110 .

[0092] In some embodiments, as shown in FIGS. 1 and 2, the stopper surface 116 is located within the mounting space 115 and on the step surface of the mounting step 1162.

[0093] 9, a stopper plate 1161 is fixed to the inner case 113, and the stopper surface 116 is located at one edge of the stopper plate 1161. In some embodiments, as shown in FIGS. 8 and 9, the conductive part 112 may be provided on the side of the stopper plate 1161 away from the stopper surface 116, that is, the stopper plate 1161 can be used as the second plate 111.

[0094] In some other embodiments, as shown in FIG. 5, the fixed disk 143 is fixed to the first case 110, and the stopper surface 116 is located on the edge of the fixed disk 143 away from the wireless charging assembly 140.

[0095] Furthermore, the stopper surface 116 stops the inner frame 125 and restricts the second case 120 from being separated from the first case 110 .

[0096] In this way, the stopper surface 116 can restrict the second case 120 and the first case 110 from rotating relative to each other and separating from each other.

[0097] Preferably, as shown in Figures 2 and 3, one of the second case 120 and the first case 110 is provided with an elastic protrusion member 106, and the other of the second case 120 and the first case 110 is provided with a plurality of locking grooves 107 distributed along the circumferential direction D1 of the first case 110, and the plurality of locking grooves 107 are engaged with the elastic protrusion member 106.

[0098] Specifically, elastic protrusion members 106 are provided on second case 120, and a plurality of locking grooves 107 distributed along the circumferential direction D1 of first case 110 are provided inside first case 110, and the plurality of locking grooves 107 are locked with elastic protrusion members 106. Alternatively, elastic protrusion members 106 are provided on first case 110, and a plurality of locking grooves 107 distributed along the circumferential direction of second case 120 are provided inside second case 120, and the plurality of locking grooves 107 are locked with elastic protrusion members 106.

[0099] For example, in some embodiments, the elastic protrusion member 106 is provided on the inner case 113, the middle frame 125 has an annular structure, and the plurality of locking grooves 107 are provided on the inner ring of the middle frame 125. Also, for example, the elastic protrusion member 106 is provided on the outer ring of the middle frame 125, and the plurality of locking grooves 107 are provided on the inner surface of the outer case 114.

[0100] By arranging elastic protrusion member 106 to be engaged with locking groove 107, the relative rotation between second case 120 and first case 110 can be limited to a certain extent, which is advantageous for maintaining the stability of the posture of the device to be charged. When second case 120 is subjected to a force, second case 120 and first case 110 rotate relative to each other, and elastic protrusion member 106 disengages from the original locking groove 107, allowing second case 120 and first case 110 to rotate relative to each other. As second case 120 and first case 110 continue to rotate relative to each other, elastic protrusion member 106 is continuously engaged into new locking grooves 107 until the relative rotation between second case 120 and first case 110 stops.

[0101] Preferably, the elastic protrusion member 106 is a pogo pin. Alternatively, the elastic protrusion member 106 is an elastic member made of plastic, silicone, or rubber, connected to the second case 120 or the first case 110 via an elastic arm, and deformed by the elastic arm to disengage from or engage with the locking groove 107. In some embodiments, the elastic protrusion member 106 is formed by bending a metal sheet in a wave shape, and a deformation space is formed after the metal sheet is bent, so that the metal sheet can deform to disengage from or engage with the locking groove 107.

[0102] 1, 9, and 10, a position limiting portion 108 is preferably provided on one of the second case 120 and the first case 110, and a first position limiting surface 1091 and a second position limiting surface 1092 are preferably provided at an interval on the other of the second case 120 and the first case 110 along the circumferential direction D1 of the first case 110. The position limiting portion 108 is movably positioned between the first position limiting surface 1091 and the second position limiting surface 1092, and limits the relative rotation between the second case 120 and the first case 110 by abutting against the first position limiting surface 1091 or the second position limiting surface 1092.

[0103] In this way, the angle of relative rotation between the second case 120 and the first case 110 can be limited within a certain range, thereby reducing the effects of twisting, pulling, pressing, etc. that the conductor 230 connected to the wireless charging assembly 140 is subjected to, and reducing the risk of damage to the conductor 230. For example, the second case 120 and the first case 110 have an initial relative position, and the direction in which the second case 120 rotates relative to the first case 110 includes forward rotation and reverse rotation. In the initial relative position, the position limiting portion 108 is located at an intermediate position between the first position limiting surface 1091 and the second position limiting surface 1092 along the circumferential direction D1 of the first case 110, and the second case 120 cannot rotate 170° in the forward direction relative to the first case 110 and abut against the first position limiting surface 1091 to continue rotating, and the second case 120 cannot rotate 170° in the reverse direction relative to the first case 110 and abut against the second position limiting surface 1092 to continue rotating, thereby limiting the twisting, pulling, pressing, and other forces that the conductor 230 receives.

[0104] Of course, in some embodiments, the position limiting portion 108, the first position limiting surface 1091, and the second position limiting surface 1092 may not be provided on the second case 120 and the first case 110 so that the second case 120 and the first case 110 can rotate relative to each other more than once.

[0105] In some embodiments, the second case 120 and the first case 110 may be rotatably connected by a screw thread. The first position limiting surface 1091 and the second position limiting surface 1092 may be provided at both ends of the screw thread.

[0106] Preferably, the first position limiting surface 1091 and the second position limiting surface 1092 may be flat or curved.

[0107] Preferably, protrusions are formed on each of the second case 120 and the first case 110, and the protrusion formed on one of the second case 120 and the first case 110 may be the position limiting portion 108, and the first position limiting surface 1091 and the second position limiting surface 1092 may be on both side surfaces of a protrusion formed on the other of the second case 120 and the first case 110, respectively. Alternatively, the first position limiting surface 1091 and the second position limiting surface 1092 may be located on two different protrusions formed on the other of the second case 120 and the first case 110, respectively. Furthermore, the first position limiting surface 1091 and the second position limiting surface 1092 are provided on the first case 110, and the position limiting portion 108 is formed at a position where the elastic protrusion is provided on the inner frame 125. This is advantageous for achieving a compact layout in the second case 120.

[0108] Furthermore, position limiting portion 108, first position limiting surface 1091, and second position limiting surface 1092 are configured so that the angle of relative rotation between second case 120 and first case 110 is greater than 90° and less than 180°. This facilitates the device to be charged to adjust its position and reduces the force acting on conductive wire 230. For example, if the device to be charged is a mobile phone, the mobile phone may lose its orientation when the user places it on wireless charging module 100. The user can then rotate the mobile phone a certain angle along circumferential direction D1 of first case 110 to straighten the mobile phone. Then, the user can rotate the mobile phone 90° in the same direction to switch between portrait mode and landscape mode. The sum of the two rotation angles is greater than 90°. If the angle of relative rotation between second case 120 and first case 110 does not exceed 90°, it is difficult for the device to adjust its position. Therefore, in the initial relative position, the angle by which the second case 120 can rotate in the forward direction and the angle by which it can rotate in the reverse direction relative to the first case 110 may both be set close to 180°, for example, may be set to 140° to 155°, or may be set to greater than 155° and less than 175°.

[0109] Preferably, as shown in FIGS. 1 and 2, the second case 120 is rotatable relative to the first case 110 about a first reference axis L1. The support mechanism 200 is rotatably connected to the first case 110, and both the second case 120 and the first case 110 are rotatable relative to the support mechanism 200 about a second reference axis L2. The extension direction of the first reference axis L1 intersects with the extension direction of the second reference axis L2. Furthermore, the first reference axis L1 is perpendicular to the second reference axis L2. In other words, the first reference axis L1 is the rotation axis about which the second case 120 rotates relative to the first case 110, and the second reference axis L2 is the rotation axis about which the first case 110 rotates relative to the support mechanism 200.

[0110] In this way, by increasing the degree of freedom of movement of the second case 120, the degree of freedom of movement of the device to be charged can be increased, making it easier to adjust the posture of the device to be charged. Furthermore, when the wireless charging device 1 is operating, the second reference axis L2 is parallel or approximately parallel to the horizontal plane, and in this way, the tilt angle of the device to be charged can be adjusted. For example, if the device to be charged is a mobile phone, adjusting the tilt angle of the mobile phone makes it easier for the user to view the mobile phone.

[0111] In some embodiments, the second case 120 has a cylindrical outer surface, and the first reference axis L1 is located at the center axis of the outer surface of the second case 120.

[0112] In some embodiments, the second case 120 has a flat support area for placing the device to be supported, and the second reference axis L2 is provided so as to be parallel to the support area.

[0113] Furthermore, the direction in which the first reference axis L1 extends is perpendicular to the direction in which the second reference axis L2 extends.

[0114] Preferably, as shown in FIG. 1 , the support rod 220 is rotatable relative to the base 210 about a third reference axis L3. The extension direction of the third reference axis L3 is perpendicular to the height direction of the support mechanism 200. In this manner, the tilt angle of the device to be charged can be adjusted by rotating the support rod 220 relative to the base 210. The third reference axis L3 is the axis of rotation about which the support rod 220 rotates relative to the base 210. In some embodiments, the third reference axis L3 is parallel to the second reference axis L2. In some other embodiments, the extension direction of the third reference axis L3 is perpendicular to the extension direction of the second reference axis L2.

[0115] Preferably, as shown in FIG. 1 , the base 210 includes a first base body and a second base body rotatably connected to each other, and the first base body is rotatable relative to the second base body about a fourth reference axis L4. The fourth reference axis L4 is a rotation axis about which the first base body rotates relative to the second base body. Furthermore, the fourth reference axis L4 intersects with the second reference axis L2. For example, the third reference axis L3 extends in the height direction of the support mechanism 200, and the second reference axis L2 is perpendicular to the height direction of the support mechanism 200. This advantageously increases the degree of freedom of movement of the device to be charged. In some embodiments, the device to be charged can rotate 360° about the fourth reference axis L4 by rotating the first base body and the second base body relative to each other at least once.

[0116] Preferably, the outer peripheral surface of the first case 110 is a portion of an approximately spherical surface, the support mechanism 200 is connected to the center position of the outer peripheral surface of the first case 110, and the center position of the outer peripheral surface of the first case 110 is protruded outward, thereby reducing the probability of the support mechanism 200 and the first case 110 interfering with each other during relative rotation.

[0117] Preferably, as shown in FIGS. 1 and 2, the support mechanism 200 includes a support rod 220 and a base 210 connected to each other, and the support rod 220 is rotatably connected to the first case 110.

[0118] In some other embodiments, the support rod 220 is fixedly connected to the first case 110 .

[0119] Preferably, as shown in Figures 1 to 4, the support mechanism 200 is provided with a ball head 201, a connecting groove 117 is formed in the first case 110, an elastic member 118 is provided in the connecting groove 117, and the ball head 201 is rotatably inserted into the connecting groove 117 and elastically abuts against the elastic member 118.

[0120] When the support mechanism 200 and the first case 110 rotate relative to each other, the ball head portion 201 rotates within the connecting groove 117 and can slide against the elastic member 118. Because the ball head portion 201 is inserted into the connecting groove 117, separation between the support mechanism 200 and the first case 110 can be restricted, and the first case 110 can shield the ball head portion 201, improving the aesthetic appearance. By elastically abutting the ball head portion 201 against the elastic member 118, the rotation resistance of the ball head portion 201 within the connecting groove 117 is increased, and it is possible to prevent the ball head portion 201 from becoming loose and shifting from its operating position.

[0121] Preferably, the elastic member 118 forms the bottom surface of the connecting groove 117. Furthermore, the elastic member 118 is a plastic member, a silicone member, or a rubber member.

[0122] Preferably, as shown in FIGS. 1 to 4, the elastic member 118 has a first semi-cylindrical surface 119, the spherical head portion 201 has a second semi-cylindrical surface 202 abutting against the first semi-cylindrical surface 119, and the extending directions of the generatrix of the first semi-cylindrical surface 119 and the extending directions of the generatrix of the second semi-cylindrical surface 202 are both parallel to the second reference axis L2. The extending directions of the generatrix of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 being both parallel to the second reference axis L2 includes the extending directions of the generatrix of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 being approximately parallel to the second reference axis L2. Furthermore, the second reference axis L2 is the central axis of the first semi-cylindrical surface 119. The central axes of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are on the same straight line.

[0123] In this way, the support mechanism 200 and the first case 110 can rotate relatively around the second reference axis L2, making it easier to adjust the posture of the device to be charged, and also restricting the relative movement of the support mechanism 200 and the first case 110 along the second reference axis L2, which is advantageous for maintaining the stability of the support mechanism 200 in supporting the wireless charging module 100.

[0124] Preferably, the radius of curvature of the second semi-cylindrical surface 202 matches that of the first semi-cylindrical surface 119, thus improving the degree of adhesion between the second semi-cylindrical surface 202 and the first semi-cylindrical surface 119 and favoring stable contact between the elastic member 118 and the ball head portion 201.

[0125] 1 and 11, a connecting shaft 204 is preferably provided on one of the support mechanism 200 and the first case 110, and a connecting hole 203 is preferably provided on the other of the support mechanism 200 and the first case 110, and the connecting shaft 204 is inserted into the connecting hole 203 and tightly fitted into the connecting hole 203. The extending direction of the connecting shaft 204 and the connecting hole 203 is parallel to the second reference axis L2. Furthermore, the connecting shaft 204 and the connecting hole 203 are made of metal to increase their strength and service life.

[0126] In this way, when the support mechanism 200 and the first case 110 are subjected to a force, they can rotate relatively around the second reference axis L2, making it easier to adjust the posture of the device to be charged. In addition, the tight fit between the connection shaft portion 204 and the connection hole 203 can increase the frictional force and restrict the relative movement of the support mechanism 200 and the first case 110, which is advantageous for maintaining the stability of the support mechanism 200 in supporting the wireless charging module 100.

[0127] 11 , a connecting shaft 204 is provided in the first case 110, and a connecting hole 203 is provided in the support mechanism 200. The connecting shaft 204 may include a pillar 2041 and a connecting sheet 2042. One end of the connecting sheet 2042 is arranged to surround the pillar 2041 and is located within the connecting hole 203 together with the pillar 2041. A connecting groove 117 is formed in the first case 110, and an escape hole 2031 is formed in the side wall of the connecting hole 203. The connecting hole 203 communicates with the connecting groove 117 through the escape hole 2031. The other end of the connecting sheet 2042 movably extends into the connecting groove 117 through the escape hole 2031 and is fixed within the connecting groove 117. In this manner, the connecting shaft 204 can rotate within the connecting hole 203, facilitating assembly and connection of the support mechanism 200 and the first case 110.

[0128] In some embodiments, the connection shaft portion 204 may not include the pillar 2041, and the portion located within the connection hole 203 of the connection sheet 2042 may have a ring-shaped structure with an opening, and the conductive wire 230 may pass through the ring-shaped structure with an opening of the connection sheet 2042 into the connection groove 117 and further be electrically connected to the wireless charging assembly 140.

[0129] As described above, according to this embodiment, when the user adjusts the attitude of the device to be charged along the circumferential direction D1 of the first case 110, the second case 120 and the device to be charged can rotate synchronously, so there is no sliding friction between the second case 120 and the device to be charged, which is advantageous in improving the smoothness of rotation of the device to be charged and improving the feel in the user's hand. For example, the device to be charged may be a mobile phone, and by rotating the device to be charged relative to the first case 110, the attitude of the mobile phone can be adjusted to switch the mobile phone between portrait mode and landscape mode, and the mobile phone can be straightened out of a distorted state.

[0130] The above are merely examples of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent flow transformation created using the contents of the specification and drawings of the present application, or any direct or indirect operation in other related technical fields, are all similarly included in the patent protection scope of the present application.
