[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] After long-term research, the inventors have found that with the development of science and technology, wireless chargers that are convenient for users to perform charging operations have emerged. Wireless chargers can be used to charge electronic devices such as mobile phones, headphones, and watches. The wireless charger can be provided with a structure to limit the position of the device to be charged to maintain the stability of the device to be charged during the charging process. At present, when the wireless charger in the prior art limits the position of the device to be charged, it is not convenient to adjust the posture of the device to be charged, which has an adverse effect on the user's experience. In order to solve this technical problem, the present application provides the following embodiments.

[0020] like Figures 1 to 3 As shown, the wireless charging device 1 described in the embodiment of the wireless charging device of the present application includes a wireless charging module 100 and a supporting mechanism 200. The wireless charging module 100 includes a first shell 110, a second shell 120, a magnetic suction component 130 and a wireless charging component 140. Among them, the second shell 120 is rotatably connected to the first shell 110, and the second shell 120 is rotatable along the circumferential direction D1 of the first shell 110. The wireless charging component 140 is connected to the second shell 120 or the first shell 110, and is used to charge the device to be charged. The magnetic suction component 130 is connected to the second shell 120 or the first shell 110, and a charging area 123 corresponding to the wireless charging component 140 is formed on the second shell 120, and the magnetic suction component 130 is used to limit the device to be charged to the charging area 123 by magnetic force. The supporting mechanism 200 is connected to the first shell 110 to support the wireless charging module 100.

[0021] By using the support mechanism 200 to support the wireless charging module 100, it is beneficial for the wireless charging module 100 to maintain its own posture stability when carrying the device to be charged. Furthermore, the support mechanism 200 can be used to raise the wireless charging module 100 so that the wireless charging module 100 and the device to be charged are spaced from the placement surface of the wireless charging device 1, which facilitates the wireless charging module 100 and the device to be charged to rotate relative to the first housing 110.

[0022] The device to be charged sometimes needs to adjust its posture when charging. For example, the device to be charged may be a mobile phone, and the posture of the mobile phone can be adjusted by rotating the device to be charged relative to the first housing 110, so that the mobile phone can switch between the horizontal and vertical screens. For another example, the device to be charged may be a mobile phone, and a crooked mobile phone can be straightened by rotating the device to be charged relative to the first housing 110.

[0023] By setting the second shell 120 and the first shell 110 as a rotational connection, when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, the second shell 120 and the device to be charged can rotate synchronously, so that there is no sliding friction between the second shell 120 and the device to be charged, or the sliding friction between the second shell 120 and the device to be charged can be reduced, which is beneficial to improve the rotation smoothness of the device to be charged, facilitate the adjustment of the posture of the device to be charged, and enhance the user feel.

[0024] Optionally, the support mechanism 200 may be electrically connected to the wireless charging module 100 at the first housing 110, so that the wireless charging module 100 can be connected to the power source through the support mechanism 200. In some embodiments, the wire 230 may extend from the support mechanism 200 through the first housing 110 into the wireless charging module 100 and be electrically connected to the wireless charging component 140. When the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first housing 110, the first housing 110 may not rotate with the device to be charged. In this way, the torsion, stretching, extrusion, etc. of the wire 230 can be reduced, and the risk of damage to the wire 230 can be reduced.

[0025] Alternatively, if Figures 1 to 3 As shown, the wireless charging component 140 may include a transmitting coil 141 and a magnetic isolation sheet 142. The transmitting coil 141 is used to charge the device to be charged, and the magnetic isolation sheet 142 is used to reduce electromagnetic interference and improve charging efficiency. Further, the wireless charging device 1 includes a circuit board assembly 170. In some embodiments, the wireless charging component 140 may be disposed on the circuit board assembly 170 and electrically connected to the circuit board assembly 170. The circuit board assembly 170 may be used to control the charging process of the wireless charging component 140 to the device to be charged. The circuit board assembly 170 may also be used to assist the transmitting coil 141 in dissipating heat, which is beneficial to reducing the temperature of the transmitting coil 141. The circuit board assembly 170 may include at least one PCB board.

[0026] Furthermore, heat dissipation glue may be provided on the circuit board assembly 170 to promote heat dissipation of the wireless charging assembly 140 .

[0027] Optionally, the circuit board assembly 170 is disposed in the support mechanism 200. For example, the support mechanism 200 includes a base 210 and a support rod 220 connected to each other, the first shell 110 is connected to the support rod 220, and the support rod 220 is supported on the base 210 to support the wireless charging module 100. In other words, the base 210 supports the wireless charging module 100 through the support rod 220. The wire 230 can extend from the base 210 through the support rod 220 to the wireless charging module 100. In some embodiments, the circuit board assembly 170 can be disposed in the base 210 to make the wireless charging module 100 thinner and reduce the heating of the wireless charging module 100. In other embodiments, the circuit board assembly 170 includes a heat dissipation circuit board (not labeled) and a control circuit board (not shown). The control circuit board is disposed in the base 210, and the control circuit board is used to control the charging process of the wireless charging component 140 on the charged device. The heat dissipation circuit board is disposed in the wireless charging module 100, and the wireless charging component 140 is disposed on the heat dissipation circuit board and is electrically connected to the heat dissipation circuit board. The heat dissipation circuit board is used to assist the transmitting coil 141 in dissipating heat to improve the working state of the wireless charging module 100.

[0028] Optionally, the base 210 and the support rod 220 are rotatably connected. The support rod 220 rotates relative to the base 210 to drive the first housing 110 to move closer to or away from the base 210. With this arrangement, the support mechanism 200 can be folded to facilitate storage of the wireless charging device 1.

[0029] Optionally, the support rod 220 is configured to be retractable or foldable, and the support rod 220 can adjust its height through a retractable movement or a folding movement for easy storage. 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 achieve folding or extension of the support rod 220 through relative rotation.

[0030] In some embodiments, the support mechanism 200 is detachably connected to the wireless charging module 100 , and the wireless charging module 100 can be conveniently charged for charging the device to be charged after being detached. Specifically, the support mechanism 200 is detachably connected to the first housing 110 .

[0031] For example, the support mechanism 200 is detachably connected to the wireless charging module 100 via a buckle or magnetic attraction. Alternatively, a clip is provided on the support mechanism 200 for clamping the wireless charging module 100 .

[0032] In some embodiments, a battery module (not shown) is disposed in the wireless charging module 100 , and the battery module can provide power for the device to be charged.

[0033] In some embodiments, the wireless charging module 100 is provided with a charging interface (not shown), which can be connected to an external power source via a charging cable, and the external power source is used to power the device to be charged.

[0034] Furthermore, the charging interface is arranged on the first shell 110. When the wireless charging module 100 charges the device to be charged, the position of the charging cable can be easily adjusted by rotating the first shell 110 relative to the second shell 120, so that the wireless charging module 100 can charge the device to be charged in more scenarios.

[0035] Optionally, the wireless charging module 100 has a front side 102 and 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 interface is disposed on the peripheral side 104 of the wireless charging module 100. In other embodiments, the charging interface is disposed on the back side 103 of the wireless charging module 100.

[0036] In some embodiments, the support mechanism 200 is provided with a power supply interface (not shown) matching the charging interface. When the support mechanism 200 and the wireless charging module 100 are in a connected state, the power supply interface is plugged into the charging interface, so that the support mechanism 200 and the wireless charging module 100 are connected, and the wireless charging component 140 is connected to the power source through the support mechanism 200. In other embodiments, a first electrical contact (not shown) is provided on the first shell 110, and the wireless charging component 140 is electrically connected to the first electrical contact; the support mechanism 200 is provided with a second electrical contact (not shown) corresponding to the first electrical contact. When the support mechanism 200 and the first shell 110 are in a connected state, the first electrical contact abuts against the second electrical contact, so that the wireless charging component 140 is connected to the power source through the support mechanism 200.

[0037] Alternatively, if Figures 1 to 3As shown, the support rod 220 includes a main rod 221 and a branch rod 222, the main rod 221 is connected to the base 210, and the branch rod 222 is connected between the first shell 110 and the main rod 221. Furthermore, the number of branch rods 222 can be two or more, and different branch rods 222 can support different wireless chargers, so that the wireless charging device 1 can charge different devices to be charged (including mobile phones, watches, headphones, etc.). In some embodiments, the wireless chargers supported by different branch rods 222 may include wireless charging modules 100 and other types of wireless chargers. In other embodiments, the wireless chargers supported by different branch rods 222 are the same or different wireless charging modules 100. For example, the base can be set to a wireless charger for charging watches or headphones. For another example, the wireless charger supported by the branch rod 222 can charge watches or headphones.

[0038] In some embodiments, the support rod 220 is an independent rod, which can be a straight rod, a bent rod, etc. In some embodiments, the support rod 220 can include two rods or multiple rods arranged side by side. In some embodiments, the cross-sectional shape of the support rod 220 is circular or rectangular.

[0039] Optionally, the branch rod 222 is connected between the wireless charging module 100 and the main rod 221. The branch rod 222 is configured as a retractable structure, and the branch rod 222 drives the wireless charging module 100 to move closer to or away from the main rod 221 through telescopic movement. Or the branch rod 222 is rotatably connected to the main rod 221, and the branch rod 222 drives the wireless charging module 100 to move closer to or away from the main rod 221 by rotating relative to the main rod 221. For example, the branch rod 222 can adjust the angle between the branch rod 222 and the main rod 221 between 0° and 180° by rotating relative to the main rod 221, so that the branch rod 222 can switch between a working state and a folded state. When the 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 angle between the branch rod 222 and the main rod 221 is 45° to 135°, the branch rod 222 is in a working state. In this way, the wireless charging device 1 can be easily folded and stored by changing the shape of the support rod 220. The wire 230 can be passed through the branch rod 222 and the main rod 221, and when the branch rod 222 rotates relative to the main rod 221, the wire 230 can be deformed accordingly.

[0040] Optionally, 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 circumference of the main rod 221. Such a configuration can facilitate the adjustment of the position of the wireless charging module 100, which is conducive to the use of the wireless charging device 1 in more scenarios. Among them, the wire 230 can be inserted through the branch rod 222 and the main rod 221, and when the branch rod 222 rotates relative to the main rod 221, the wire 230 can be deformed accordingly.

[0041] Optionally, the wireless charging module 100 includes a back wireless charging component, a back charging area corresponding to the back wireless charging component 140 is formed on the first shell 110, and the back wireless charging component is connected to the second shell 120 or the first shell 110, and is used to charge another device to be charged in the back charging area. In this way, the wireless charging module 100 can charge different devices to be charged at the same time, which is conducive to improving the functional richness of the wireless charging module 100.

[0042] Optionally, the wireless charging module 100 includes a back wireless charging component and a third shell, a back charging area corresponding to the back wireless charging component is formed on the third shell, the third shell is rotatably connected to the first shell 110, and the third shell is rotatable along the circumferential direction D1 of the first shell 110. The wireless charging component is connected to the third shell or the first shell 110 for charging the device to be charged. The third shell and the second shell 120 can be connected through the first shell 110. In this way, the wireless charging module 100 can charge different devices to be charged at the same time, which is conducive to improving the functional richness of the wireless charging module 100.

[0043] Optionally, another device to be charged can be magnetically restrained in the back charging area by the magnetic attraction component 130, or can be attracted to the back charging area by other magnets. Further, the back charging area and the charging area 123 are located on two opposite sides of the wireless charging module 100.

[0044] Optionally, a battery module (not shown) is disposed in the base 210 , and the battery module is used to supply power to the wireless charging device 1 .

[0045] Alternatively, if Figure 2 and Figure 3 As shown, the magnetic attraction assembly 130 includes a plurality of magnets arranged along the circumferential direction D1 of the first housing 110. Furthermore, the plurality of magnets are spliced ​​to form a ring structure with a break, which is convenient for installation and meets the installation specifications.

[0046] Optionally, the magnetic attraction component 130 is disposed around the outer periphery of the wireless charging component 140 along the circumferential direction D1 of the first shell 110 .

[0047] Alternatively, if Figures 1 to 3 As shown, the second shell 120 and the first shell 110 are arranged to form a receiving space 160 , the magnetic attraction component 130 and the wireless charging component 140 are both located in the receiving space 160 , and a charging area 123 corresponding to the wireless charging component 140 is formed on the side of the second shell 120 facing away from the receiving space 160 .

[0048] In this way, the second shell 120 and the first shell 110 can protect and shield the magnetic attraction component 130 and the wireless charging component 140 , which is beneficial to improving the structural stability of the wireless charging module 100 .

[0049] Alternatively, if Figures 1 to 4 As shown, the magnetic attraction component 130 is connected to the second shell 120, and the wireless charging component 140 is connected to the first shell 110, so that the device to be charged and the second shell 120 and the magnetic attraction component 130 can rotate together along the circumferential direction D1 of the first shell 110 relative to the first shell 110 and the wireless charging component 140.

[0050] Such an arrangement allows the second shell 120, the magnetic component 130 and the device to be charged to rotate synchronously when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, so that there is no sliding friction between the second shell 120 and the device to be charged, and at the same time, the resistance of the magnetic component 130 to the rotation of the device to be charged is reduced, which is conducive to improving the smoothness of the rotation of the device to be charged and reducing the effort of the user. In addition, in some embodiments, the wire 230 is passed through the first shell 110 and extends to the wireless charging component 140 to connect with the wireless charging component 140. By setting the wireless charging component 140 and the first shell 110 to be connected, the wireless charging component 140 and the first shell 110 can remain relatively fixed, which is conducive to reducing the torsion, stretching, extrusion and other effects on the wire 230, and reducing the risk of damage to the wire 230.

[0051] Furthermore, there is a gap between the wireless charging component 140 and the magnetic component 130 , that is, the wireless charging component 140 and the magnetic component 130 are not in contact with each other, thereby reducing the resistance of the wireless charging component 140 to the rotation of the magnetic component 130 .

[0052] In some embodiments, the wireless charging component 140 is detachably connected to the first housing 110. In other embodiments, the wireless charging component 140 is fixedly connected to the first housing 110, for example, by glue.

[0053] In some embodiments, the magnetic component 130 is detachably connected to the second housing 120. In other embodiments, the magnetic component 130 is fixedly connected to the second housing 120, for example, by glue.

[0054] Alternatively, if Figure 1 , Figures 5 to 7 As shown, the magnetic component 130 and the wireless charging component 140 are both connected to the first shell 110 so that the device to be charged and the second shell 120 can rotate together along the circumferential direction D1 of the first shell 110 relative to the first shell 110 , the wireless charging component 140 and the magnetic component 130 .

[0055] In this way, when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, there may be no sliding friction between the second shell 120 and the device to be charged, which is beneficial to improving the rotation smoothness of the device to be charged, and is also beneficial to reducing the torsion, stretching, extrusion and other effects on the wire 230 connected to the wireless charging component 140, thereby reducing the risk of damage to the wire 230.

[0056] In some embodiments, the magnetic attraction component 130 and the wireless charging component 140 are both fixedly connected to the first shell 110 .

[0057] In some embodiments, during the assembly process, the magnetic component 130 and the wireless charging component 140 can be pre-fixed using a fixing plate 143, and then the fixing plate 143, the magnetic component 130 and the wireless charging component 140 are assembled together on the first shell 110, which is helpful to improve assembly efficiency.

[0058] In some embodiments, the magnetic attraction component 130 and the wireless charging component 140 are both detachably connected to the first shell 110 .

[0059] Alternatively, if Figure 1 , Figures 8 to 10 As shown, the magnetic component 130 and the wireless charging component 140 are both connected to the second shell 120 , so that the device to be charged and the second shell 120 , the wireless charging component 140 , and the magnetic component 130 can rotate relative to the first shell 110 along the circumferential direction D1 of the first shell 110 .

[0060] In this way, when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, there is no sliding friction between the second shell 120 and the device to be charged, which is conducive to improving the smoothness of the rotation of the device to be charged and reducing the resistance of the magnetic component 130 to the rotation of the device to be charged. In addition, by setting the wireless charging component 140 and the device to be charged to rotate synchronously, it is conducive to improving the stability of the wireless charging component 140 charging the device to be charged.

[0061] Specifically, sliding friction refers to the friction between the second shell 120 and the supported device when they slide relative to each other, and the friction between the second shell 120 and the supported device when they are relatively fixed is static friction. In some embodiments, the second shell 120 has a strong magnetic attraction to the device to be charged, or the friction coefficient between the second shell 120 and the device to be charged is large. When the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, there is no sliding friction between the second shell 120 and the device to be charged, that is, the second shell 120 and the device to be charged rotate completely synchronously. In other embodiments, the second shell 120 has a weak magnetic attraction to the device to be charged, or the friction coefficient between the second shell 120 and the device to be charged is small. When the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, there is sliding friction between the second shell 120 and the device to be charged, that is, the second shell 120 and the device to be charged do not rotate completely synchronously.

[0062] In some embodiments, the magnetic attraction component 130 and the wireless charging component 140 are both fixedly connected to the second shell 120 .

[0063] In some embodiments, the magnetic attraction component 130 and the wireless charging component 140 are both detachably connected to the second housing 120 .

[0064] Alternatively, if Figure 8 As shown, the wireless charging module 100 includes two elastic conductive contacts 122 and two conductive parts 112 that are respectively abutted, the two elastic conductive contacts 122 are arranged in one of the second shell 120 and the first shell 110, and the two conductive parts 112 are arranged in the other of the second shell 120 and the first shell 110. The wireless charging component 140 is connected to the power source through the two elastic conductive contacts 122 and the two conductive parts 112.

[0065] Specifically, the wireless charging module 100 includes an elastic conductive contact 122 and a conductive part 112 that are correspondingly abutted and can slide relative to each other. The elastic conductive contact 122 is disposed on the second shell 120 and is electrically connected to the wireless charging component 140, and the conductive part 112 is disposed on the first shell 110 and is electrically connected to the power source through the wire 230, so that the wireless charging component 140 is electrically connected to the power source through the elastic conductive contact 122 and the conductive part 112. Or the conductive part 112 is disposed on the second shell 120 and is electrically connected to the wireless charging component 140, and the elastic conductive contact 122 is disposed on the first shell 110 and is electrically connected to the power source through the wire 230, so that the wireless charging component 140 is electrically connected to the power source through the elastic conductive contact 122 and the conductive part 112.

[0066] The elastic conductive contacts 122 and the conductive parts 112 can be set to two or more, for example, three or four. The two elastic conductive contacts 122 and the two conductive parts 112 can be abutted one by one. The area of ​​the conductive part 112 for the elastic conductive contacts 122 to abut can be larger than the area of ​​the elastic conductive contacts 122 for abutting the conductive part 112, so when the second shell 120 and the first shell 110 rotate relative to each other, the elastic conductive contacts 122 can slide relative to the corresponding conductive parts 112 and will not be separated from the corresponding conductive parts 112.

[0067] For example, the first housing 110 is fixedly disposed relative to the conductive portion 112, and the second housing 120 is fixedly disposed relative to the elastic conductive contact 122. The power source may be a power grid output terminal, or may refer to a battery module disposed in the base 210. The wire 230 is led out from the power source and can extend to connect with the conductive portion 112, and the wireless charging component 140 is connected with the elastic conductive contact 122, so that the wireless charging component 140 can be connected to the power source.

[0068] By providing relatively sliding elastic conductive contacts 122 and conductive parts 112 to replace part of the wire 230, the wire 230 is not easily twisted and damaged when the second shell 120 and the first shell 110 rotate relative to each other, and the wire 230 will not pull the wireless charging component 140 to hinder the relative rotation of the second shell 120 and the first shell 110, which is beneficial to improving the service life of the wireless charging device 1 and improving the rotation smoothness of the device to be charged.

[0069] Optionally, the elastic conductive contact 122 may be a spring pin type connector.

[0070] Optionally, the conductive part 112 is a metal foil, such as copper foil, aluminum foil, etc. The elastic conductive contact 122 is a spring pin.

[0071] In some embodiments, the conductive contacts are non-elastic conductive contacts.

[0072] Alternatively, if Figure 8 As shown, one of the two conductive portions 112 is annular and is disposed around the other of the two conductive portions 112 .

[0073] For example, one of the two conductive parts 112 is annular and the other is circular, and the annular conductive part 112 surrounds the circular conductive part 112. Correspondingly, when the second shell 120 and the first shell 110 rotate relative to each other, the elastic conductive contact 122 abutting against the annular conductive part 112 slides along the circumference of the annular conductive part 112, and the sliding track surrounds the elastic conductive contact 122 abutting against the circular conductive part 112. Further, when the second shell 120 and the first shell 110 rotate relative to each other, the elastic conductive contact 122 abutting against the circular conductive part 112 performs self-rotation motion. For another example, both conductive parts 112 are annular. For another example, both conductive parts 112 are arc-shaped.

[0074] Such an arrangement allows the second housing 120 and the first housing 110 to rotate relative to each other by a full circle or multiple circles, and is also beneficial for making the two conductive parts 112 compact while having a sufficient spacing between them, thereby improving space utilization.

[0075] Alternatively, if Figure 8 As shown, the wireless charging module 100 includes a first plate 121 and a second plate 111 arranged opposite to each other, the first plate 121 is arranged on the second housing 120 and electrically connected to the wireless charging component 140, and the second plate 111 is arranged on the first housing 110. Two elastic conductive contacts 122 are arranged on one of the first plate 121 and the second plate 111, and two conductive parts 112 are arranged on the other of the first plate 121 and the second plate 111.

[0076] By respectively arranging the elastic conductive contact 122 and the conductive part 112 on the first plate 121 and the second plate 111, it is convenient to assemble the wireless charging module 100, improve the connection stability between the elastic conductive contact 122 and the conductive part 112, and further improve the connection stability between the wireless charging component 140 and the power source.

[0077] For example, the two conductive parts 112 may be printed on the surface of the first plate 121 or the second plate 111 .

[0078] Furthermore, the first plate body 121 and the second plate body 111 may be spaced apart from each other, which is beneficial to the heat dissipation of the wireless charging component 140 .

[0079] Optionally, the first board 121 may be the heat dissipation circuit board, the control circuit board, or the circuit board assembly 170. The second board 111 may be a circuit board, which facilitates the connection between the conductive part 112 or the elastic conductive contact 122 and the wire 230.

[0080] Alternatively, if Figures 2 to 4As shown, a bearing 151 is disposed between the second housing 120 and the first housing 110 . The second housing 120 and the first housing 110 rotate relative to each other through the bearing 151 .

[0081] The bearing 151 is provided to improve the smoothness of the relative rotation between the second housing 120 and the first housing 110 , and the bearing 151 can be easily assembled.

[0082] Optionally, the inner ring of the bearing 151 is sleeved on the first housing 110, and the second housing 120 is sleeved on the outer ring of the bearing 151. Such a configuration is conducive to reducing the size of the first housing 110 and increasing the size of the second housing 120. On the one hand, due to the shielding of the second housing 120, the first housing 110 is not easily visible from the side where the wireless charging module 100 adsorbs the device to be charged, which is conducive to improving the appearance. On the other hand, it is conducive to increasing the area of ​​the surface of the first housing 110 where the device to be charged is placed.

[0083] Alternatively, if Figures 2 to 4 As shown, the first housing 110 includes an inner housing 113 and an outer housing 114. The second housing 120 and the inner housing 113 are surrounded to form a receiving space 160, and the magnetic attraction component 130 and the wireless charging component 140 are located in the receiving space 160. The outer housing 114 is located at the periphery of the inner housing 113, and an installation space 115 is formed between the outer housing 114 and the inner housing 113. The bearing 151 is arranged in the installation space 115 and sleeved on the outer periphery of the inner housing 113. The second housing 120 extends into the installation space 115 and abuts against the outer ring of the bearing 151.

[0084] By arranging the bearing 151 in the installation space 115, the outer shell 114 can shield and protect the bearing 151, which is beneficial for the bearing 151 to maintain a stable assembly relationship with the inner shell 113 and the second shell 120, thereby improving the structural stability of the wireless charging module 100 and improving the appearance of the wireless charging module 100.

[0085] Furthermore, the wireless charging component 140 may be installed in the inner housing 113 , and a heat dissipation space 1131 may be opened on the inner housing 113 to promote heat dissipation of the wireless charging component 140 .

[0086] Optionally, both the inner shell 113 and the outer shell 114 are provided with reinforcing ribs 1132 to increase strength, which is beneficial for uniform wall thickness and can reduce surface collapse caused by uneven shrinkage during molding.

[0087] Alternatively, if Figures 2 to 4 As shown, the outer periphery of the inner housing 113 has a mounting step 1162 , and the bearing 151 can be mounted on the mounting step 1162 , so as to facilitate the installation of the bearing 151 .

[0088] Optionally, the inner housing 113 and the outer housing 114 may be fixed together by screws.

[0089] Alternatively, if Figures 2 to 4 As shown, the second shell 120 includes an upper cover 124 and a middle frame 125. One end of the middle frame 125 has an installation port (not marked), through which the magnetic suction component 130 and the wireless charging component 140 can be installed, and the upper cover 124 can be used to block the installation port. The charging area 123 is located on the outside of the upper cover 124. The other end of the middle frame 125 can extend into the installation space 115 and abut against the outer ring of the bearing 151. Such a configuration can facilitate the assembly of the wireless charging module 100. In some embodiments, the magnetic suction component 130 can be fixed to the upper cover 124. In other embodiments, the above-mentioned fixed plate 143, the magnetic suction component 130 and the wireless charging component 140 can be assembled together on the upper cover 124.

[0090] Optionally, the upper cover 124 and the middle frame 125 are connected by glue or by snap fastening.

[0091] Alternatively, if Figure 1 , Figures 2 to 4 As shown, the wireless charging module 100 has a front side 102 and a back side 103 and a peripheral side 104 connected between the front side 102 and the back side 103. The front side 102 is used to adsorb the device to be charged. The support mechanism 200 is connected to the first shell 110 at the back side 103. On the outer surface of the wireless charging module 100, the seam 105 between the second shell 120 and the first shell 110 is located at the back side 103 or the peripheral side 104. In other words, the second shell 120 can shield the first shell 110 at the front side 102 of the wireless charging module 100, so that the seam 105 between the second shell 120 and the first shell 110 is located at the back side 103 or the peripheral side 104.

[0092] The seam 105 between the second shell 120 and the first shell 110 refers to the seam 105 at the junction of the second shell 120 and the first shell 110. For example, the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the wireless charging module 100 is the seam 105 between the middle frame 125 and the first shell 110. Further, the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the wireless charging module 100 is the seam 105 between the middle frame 125 and the outer shell 114.

[0093] In some embodiments, Figure 1 and Figure 2 As shown, on the outer surface of the wireless charging module 100, the seam 105 between the second shell 120 and the first shell 110 is located on the peripheral side 104. In some embodiments, as Figure 1 and Figure 4As shown, the middle frame 125 has a shielding portion 1251 located on the peripheral side surface 104 , and the shielding portion 1251 on the peripheral side surface 104 can shield the first shell 110 so that the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the wireless charging module 100 is located on the back side 103 .

[0094] Such a configuration is helpful to improve the appearance of the wireless charging device 1.

[0095] Alternatively, if Figures 5 to 7 As shown, a rolling member 152 is disposed between the second housing 120 and the first housing 110 . The second housing 120 and the first housing 110 rotate relative to each other through the rolling member 152 .

[0096] The provision of the rolling element 152 is conducive to improving the smoothness of the relative rotation between the second housing 120 and the first housing 110, and the rolling element 152 can have the characteristic of being small in size. For example, the rolling element 152 is a ball, a needle, or a cylindrical roller. There can be multiple rolling elements 152, and the multiple rolling elements 152 can be distributed at intervals or continuously along the circumferential direction D1 of the first housing 110.

[0097] In some embodiments, the rolling member 152 is located between the upper cover 124 and the first housing 110. In other embodiments, the rolling member 152 is located between the middle frame 125 and the first housing 110.

[0098] In some embodiments, a groove (not marked) is formed on one of the second shell 120 and the first shell 110 to accommodate the rolling element 152 , and the opening direction of the groove is parallel or perpendicular to the axis direction of rotation of the second shell 120 relative to the first shell 110 .

[0099] In some embodiments, the bearing 151 and the rolling element 152 may not be disposed between the second housing 120 and the first housing 110 .

[0100] Alternatively, if Figure 1 , Figure 2 , Figures 7 to 9 As shown, the first housing 110 is provided with a stop surface 116 distributed along the circumference D1 of the first housing 110, and the stop surface 116 is used to stop the second housing 120 to limit the second housing 120 from separating from the first housing 110. The stop surface 116 is distributed along the circumference D1 of the first housing 110 at intervals or continuously.

[0101] Specifically, the stop surface 116 is used to limit the second housing 120 from being separated from the first housing 110 along a direction extending relative to the rotation axis of the first housing 110 .

[0102] In some embodiments, Figure 1 and Figure 2As shown, the stop surface 116 is located in the installation space 115 and on the step surface of the above-mentioned installation step 1162.

[0103] In other embodiments, Fig. 9 As shown, a stop plate 1161 is fixed to the inner shell 113, and the stop surface 116 is located at an edge of one side of the stop plate 1161. In some embodiments, as Figure 8 and Fig. 9 As shown, the side of the stop plate 1161 away from the stop surface 116 can be used to set the above-mentioned conductive part 112, that is, the stop plate 1161 can be used as the above-mentioned second plate body 111.

[0104] In other embodiments, Figure 5 As shown, the fixing plate 143 is fixed on the first housing 110 , and the stop surface 116 is located at an edge of the fixing plate 143 which is away from the wireless charging component 140 .

[0105] Furthermore, the stopping surface 116 is used to stop the middle frame 125 to limit the second shell 120 from being separated from the first shell 110 .

[0106] In this way, the stop surface 116 allows the second housing 120 and the first housing 110 to rotate relative to each other and restricts the second housing 120 and the first housing 110 from being separated from each other.

[0107] Alternatively, if Figure 2 and Figure 3 As shown, one of the second shell 120 and the first shell 110 is provided with an elastic protrusion 106, and the other of the second shell 120 and the first shell 110 is provided with a plurality of snap grooves 107 distributed along the circumference D1 of the first shell 110, and the plurality of snap grooves 107 are used for snapping with the elastic protrusion 106.

[0108] Specifically, the second housing 120 is provided with an elastic protrusion 106, and the first housing 110 is provided with a plurality of snap grooves 107 distributed along the circumferential direction D1 of the first housing 110, and the plurality of snap grooves 107 are used to snap with the elastic protrusion 106. Or the first housing 110 is provided with an elastic protrusion 106, and the second housing 120 is provided with a plurality of snap grooves 107 distributed along the circumferential direction of the second housing 120, and the plurality of snap grooves 107 are used to snap with the elastic protrusion 106.

[0109] For example, in some embodiments, the elastic protrusion 106 is disposed on the inner shell 113, the middle frame 125 is an annular structure, and a plurality of snap grooves 107 are disposed on the inner ring of the middle frame 125. For another example, the elastic protrusion 106 is disposed on the outer ring of the middle frame 125, and a plurality of snap grooves 107 are disposed on the inner surface of the outer shell 114.

[0110] By setting the elastic protrusion 106 to engage with the snap groove 107, the relative rotation of the second shell 120 and the first shell 110 can be limited to a certain extent, which is conducive to maintaining the stability of the posture of the device to be charged. When the second shell 120 is subjected to force, the second shell 120 and the first shell 110 rotate relative to each other, and at the same time, the elastic protrusion 106 can be disengaged from the original snap groove 107 to allow the second shell 120 and the first shell 110 to rotate relative to each other. As the second shell 120 and the first shell 110 continue to rotate relative to each other, the elastic protrusion 106 will continue to be engaged in a new snap groove 107 until the second shell 120 and the first shell 110 stop rotating relative to each other.

[0111] Optionally, the elastic protrusion 106 is a spring pin. Alternatively, the elastic protrusion 106 is a component made of elastic plastic, silicone or rubber, connected to the second housing 120 or the first housing 110 through an elastic arm, and deformed by the elastic arm to disengage from or snap into the snap groove 107. In some embodiments, the elastic protrusion 106 is formed by bending a metal sheet into a corrugated shape, and a deformation space is formed after the metal sheet is bent, thereby allowing the metal sheet to deform to disengage from or snap into the snap groove 107.

[0112] Alternatively, if Figure 1 , Fig. 9 and Fig.10 As shown, one of the second housing 120 and the first housing 110 is provided with a limiting portion 108, and along the circumferential direction D1 of the first housing 110, the second housing 120 and the other of the first housing 110 are spaced apart from each other with a first limiting surface 1091 and a second limiting surface 1092. The limiting portion 108 can be movably located between the first limiting surface 1091 and the second limiting surface 1092, so as to limit the relative rotation of the second housing 120 and the first housing 110 by abutting against the first limiting surface 1091 or the second limiting surface 1092.

[0113] In this way, the angle of relative rotation between the second housing 120 and the first housing 110 can be limited within a certain range, so as to reduce the torsion, stretching, extrusion and other effects on the wire 230 connected to the wireless charging component 140, and reduce the risk of damage to the wire 230. For example, the second housing 120 and the first housing 110 have an initial relative position, and the rotation direction of the second housing 120 relative to the first housing 110 includes forward rotation and reverse rotation. In the initial relative position, the limiting portion 108 along the circumferential direction D1 of the first housing 110 is located at the middle position between the first limiting surface 1091 and the second limiting surface 1092. The second housing 120 can be rotated 170° relative to the first housing 110 in the forward direction and can abut against the first limiting surface 1091 and cannot continue to rotate. The second housing 120 can be rotated 170° relative to the first housing 110 in the reverse direction and can abut against the second limiting surface 1092 and cannot continue to rotate. Therefore, the torsion, stretching, extrusion and other effects on the wire 230 are limited.

[0114] Of course, in some embodiments, the second shell 120 and the first shell 110 may not be provided with the limiting portion 108 , the first limiting surface 1091 and the second limiting surface 1092 to allow the second shell 120 and the first shell 110 to rotate relative to each other one to multiple times.

[0115] In some embodiments, the second housing 120 and the first housing 110 can be rotatably connected via threads. The first limiting surface 1091 and the second limiting surface 1092 can be disposed at both ends of the threads.

[0116] Optionally, the first limiting surface 1091 and the second limiting surface 1092 may be planes or curved surfaces.

[0117] Optionally, protrusions are formed on the second shell 120 and the first shell 110, respectively. The protrusion formed on one of the second shell 120 and the first shell 110 can be the limiting portion 108. The first limiting surface 1091 and the second limiting surface 1092 can be the two side surfaces of the protrusion formed on the other of the second shell 120 and the first shell 110, respectively, or the first limiting surface 1091 and the second limiting surface 1092 can be respectively located on two different protrusions formed on the other of the second shell 120 and the first shell 110. Further, the first limiting surface 1091 and the second limiting surface 1092 are arranged on the first shell 110, and the position where the elastic protrusion is arranged on the middle frame 125 forms the limiting portion 108, which is conducive to a compact layout on the second shell 120.

[0118] Furthermore, the limiting portion 108, the first limiting surface 1091 and the second limiting surface 1092 are configured so that the relative rotation angle between the second shell 120 and the first shell 110 exceeds 90° and is less than 180°, so that it is convenient for the device to be charged to adjust its own posture and the force acting on the wire 230 can be reduced. For example, when the device to be charged is a mobile phone, the posture of the mobile phone will be skewed when the user places the mobile phone on the wireless charging module 100. The user can rotate the mobile phone along the circumferential direction D1 of the first shell 110 by a certain angle to straighten the mobile phone, and then the user can rotate 90° in the same direction to switch between horizontal and vertical screens. The sum of the two rotation angles will be greater than 90°. If the relative rotation angle between the second shell 120 and the first shell 110 does not exceed 90°, it is not conducive to the device to be charged to adjust its own posture. Therefore, in the initial relative position, the second shell 120 can rotate forwardly and backward relative to the first shell 110 to an angle close to 180°, for example, 140° to 155°, or greater than 155° and less than 175°.

[0119] Alternatively, if Figure 1 and Figure 2As shown, the second housing 120 is rotatable relative to the first housing 110 around the first reference axis L1. The support mechanism 200 and the first housing 110 are rotatably connected, and the second housing 120 and the first housing 110 are rotatable relative to the support mechanism 200 around the second reference axis L2. The extension direction of the first reference axis L1 intersects with the extension direction of the second reference axis L2. Further, 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 of the second housing 120 relative to the first housing 110, and the second reference axis L2 is the rotation axis of the first housing 110 relative to the support mechanism 200.

[0120] Such a configuration can increase the freedom of movement of the second housing 120, thereby increasing the freedom of movement of the device to be charged, and facilitating the adjustment of the posture of the device to be charged. Furthermore, when the wireless charging device 1 is working, the second reference axis L2 is parallel or approximately parallel to the horizontal plane, so that the pitch angle of the device to be charged can be adjusted. For example, when the device to be charged is a mobile phone, by adjusting the pitch angle of the mobile phone, it is convenient for the user to watch the mobile phone.

[0121] In some embodiments, the second shell 120 has a cylindrical outer surface, and the first reference axis L1 is located at a central axis position of the outer surface of the second shell 120 .

[0122] In some embodiments, the second housing 120 has a flat supporting area for placing the device to be supported, and the second reference axis L2 is arranged parallel to the supporting area.

[0123] Further, the extension direction of the first reference axis L1 is perpendicular to the extension direction of the second reference axis L2.

[0124] Alternatively, if Figure 1 As shown, the support rod 220 can rotate relative to the base 210 around the 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 way, the support rod 220 can adjust the pitch angle of the device to be charged by rotating relative to the base 210. The third reference axis L3 is the rotation axis of the support rod 220 relative to the base 210. In some embodiments, the third reference axis L3 is parallel to the second reference axis L2. In other embodiments, the extension direction of the third reference axis L3 is perpendicular to the extension direction of the second reference axis L2.

[0125] Alternatively, if Figure 1As shown, the base 210 includes a first base body and a second base body that are rotatably connected, and the first base body is rotatable relative to the second base body around a fourth reference axis L4. The fourth reference axis L4 is the rotation axis of the first base body relative to the second base body. Further, the fourth reference axis L4 intersects with the second reference axis L2. For example, the third reference axis L3 extends along 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. Such a configuration is conducive to increasing the freedom of movement of the device to be charged. In some embodiments, the first base body and the second base body can rotate relative to each other at least one circle, and a 360° rotation of the device to be charged around the fourth reference axis L4 can be achieved.

[0126] Optionally, the outer circumferential surface of the first shell 110 is approximately a part of a sphere, the support mechanism 200 is connected to the center position of the outer circumferential surface of the first shell 110, and the center position of the outer circumferential surface of the first shell 110 is protruded outward, thereby reducing the probability of mutual interference between the support mechanism 200 and the first shell 110 during relative rotation.

[0127] Alternatively, if Figure 1 and Figure 2 As shown, 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 shell 110 .

[0128] In some other embodiments, the support rod 220 is fixedly connected to the first shell 110 .

[0129] Alternatively, if Figures 1 to 4 As shown, a ball head 201 is provided on the support mechanism 200 , a connecting groove 117 is opened on the first shell 110 and an elastic member 118 is provided in the connecting groove 117 , and the ball head 201 can rotatably extend into the connecting groove 117 and elastically abut against the elastic member 118 .

[0130] When the support mechanism 200 and the first shell 110 rotate relative to each other, the ball head 201 can rotate in the connection groove 117 and slide relative to the elastic member 118. The ball head 201 can be inserted into the connection groove 117, thereby limiting the support mechanism 200 from being separated from the first shell 110. The first shell 110 can cover the ball head 201 to improve the appearance. By elastically contacting the ball head 201 with the elastic member 118, the rotation resistance of the ball head 201 in the connection groove 117 can be increased, preventing the ball head 201 from deviating from the working position due to looseness.

[0131] Optionally, the elastic member 118 forms the bottom surface of the connecting groove 117. Further, the elastic member 118 is a plastic member, a silicone member or a rubber member.

[0132] Alternatively, if Figures 1 to 4As shown, the elastic member 118 has a first semi-cylindrical surface 119, and the ball head 201 has a second semi-cylindrical surface 202 abutting against the first semi-cylindrical surface 119, and the generatrix extension direction of the first semi-cylindrical surface 119 and the generatrix extension direction of the second semi-cylindrical surface 202 are both parallel to the second reference axis L2. Among them, the generatrix extension direction of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are both parallel to the second reference axis L2, which also includes: the generatrix extension direction of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 can also be approximately parallel to the second reference axis L2. Further, 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 collinear.

[0133] Such a configuration allows the support mechanism 200 and the first shell 110 to rotate relative to each other around the second reference axis L2 to facilitate adjustment of the posture of the device to be charged. It can also limit the relative movement of the support mechanism 200 and the first shell 110 along the second reference axis L2, which is beneficial to maintaining the support stability of the support mechanism 200 on the wireless charging module 100.

[0134] Optionally, the curvature of the second semi-cylindrical surface 202 matches that of the first semi-cylindrical surface 119 , which can improve the fit between the second semi-cylindrical surface 202 and the first semi-cylindrical surface 119 , and is conducive to stable contact between the elastic member 118 and the ball head 201 .

[0135] Alternatively, if Figure 1 and Fig.11 As shown, one of the support mechanism 200 and the first housing 110 is provided with a connecting shaft section 204, and the other of the support mechanism 200 and the first housing 110 is provided with a connecting hole 203, and the connecting shaft section 204 is inserted into the connecting hole 203 and is interference-fitted with the connecting hole 203. The extending directions of the connecting shaft section 204 and the connecting hole 203 are parallel to the second reference axis L2. Further, the connecting shaft section 204 and the connecting hole 203 are made of metal to improve strength and service life.

[0136] Such a configuration allows the support mechanism 200 and the first shell 110 to rotate relative to each other around the second reference axis L2 when subjected to force, so as to adjust the posture of the device to be charged. The friction force can also be increased by the interference fit between the connecting shaft segment 204 and the connecting hole 203, thereby limiting the relative movement of the support mechanism 200 and the first shell 110 to a certain extent, which is beneficial to the supporting stability of the support mechanism 200 for the wireless charging module 100.

[0137] In some embodiments, Fig.11As shown, the first housing 110 is provided with a connecting shaft section 204, and the supporting mechanism 200 is provided with a connecting hole 203. The connecting shaft section 204 may include a column 2041 and a connecting piece 2042, one end of the connecting piece 2042 is arranged around the column 2041 and is located in the connecting hole 203 with the column 2041, a connecting groove 117 is provided on the first housing 110, a sidewall of the connecting hole 203 is provided with an avoidance opening 2031 and is connected with the connecting groove 117 through the avoidance opening 2031, and the other end of the connecting piece 2042 can movably extend through the avoidance opening 2031 into the connecting groove 117 and be fixed in the connecting groove 117. Such a configuration allows the connecting shaft section 204 to rotate in the connecting hole 203, which can facilitate the assembly connection between the supporting mechanism 200 and the first housing 110.

[0138] In some embodiments, the connecting shaft segment 204 may not include the column 2041, and the portion of the connecting piece 2042 located in the connecting hole 203 is a ring structure with an opening. The wire 230 can pass through the ring structure with an opening of the connecting piece 2042 into the connecting groove 117, and then be electrically connected to the wireless charging component 140.

[0139] To sum up, this embodiment can achieve that when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first shell 110, the second shell 120 and the device to be charged can rotate synchronously, so that there is no sliding friction between the second shell 120 and the device to be charged, which is beneficial to improving the rotation smoothness of the device to be charged and enhancing the user's feel. For example, the device to be charged can be a mobile phone. The posture of the mobile phone can be adjusted by rotating the device to be charged relative to the first shell 110, so that the mobile phone can switch between horizontal and vertical screens, and the mobile phone can also be straightened from a skewed state.
