Description

Technical Field

[0001] This application relates to the field of wireless charging technology, and in particular to a wireless charging device. Background Technology

[0002] In daily life, people often need to use various electronic products, many of which require frequent charging. Traditional wired charging is rather cumbersome. With the development of technology, wireless chargers, which are easier for users to charge, have emerged. Wireless chargers can be used to charge electronic devices such as mobile phones, headphones, and watches.

[0003] Wireless chargers can be equipped with a structure that limits the position of the device being charged to maintain stability during the charging process. Currently, in existing wireless chargers, limiting the position of the device makes it difficult to adjust the device's posture, negatively impacting the user experience. Summary of the Invention

[0004] The main technical problem addressed by this application is to provide a wireless charging device that can improve the smoothness of rotation of the device being charged and facilitate the adjustment of the device's posture.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is: to provide a wireless charging device. The wireless charging device includes a wireless charging module and a supporting mechanism. The wireless charging module includes a first housing, a second housing, a magnetic suction component, and a wireless charging component. The second housing is rotatably connected to the first housing, and the second housing is rotatable along the circumference of the first housing. The wireless charging component is connected to either the second housing or the first housing and is used to charge a device to be charged. The magnetic suction component is connected to either the second housing or the first housing, and a charging area corresponding to the wireless charging component is formed on the second housing. The magnetic suction component is used to magnetically confine the device to be charged within the charging area. The supporting mechanism is connected to the first housing and is used to support the wireless charging module.

[0006] The beneficial effects of this application are as follows: Unlike the prior art, the wireless charging module includes a first housing, a second housing, a magnetic component, and a wireless charging component. The second housing is rotatably connected to the first housing and can rotate around the circumference of the first housing. The wireless charging component is connected to either the second or first housing for charging the device to be charged. The magnetic component is connected to either the second or first housing. A charging area corresponding to the wireless charging component is formed on the second housing. The magnetic component is used to magnetically confine the device to be charged within the charging area. A support mechanism is connected to the first housing for supporting the wireless charging module. When the user adjusts the posture of the device to be charged along the circumference of the first housing, the second housing and the device to be charged can rotate synchronously. Therefore, there is no sliding friction between the second housing and the device to be charged, or the sliding friction between the second housing and the device to be charged can be reduced. This improves the smoothness of the rotation of the device to be charged, facilitates the adjustment of the posture of the device to be charged, and enhances the user's feel. For example, the device to be charged can be a mobile phone. By rotating the device to be charged relative to the first housing, the posture of the mobile phone can be adjusted, allowing the mobile phone to switch between portrait and landscape modes, or to straighten the mobile phone from a tilted state.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Through long-term research, the inventors have discovered that with the development of technology, wireless chargers that facilitate user charging have emerged. Wireless chargers can be used to charge electronic devices such as mobile phones, headphones, and watches. Wireless chargers can be equipped with a structure that limits the position of the device being charged to maintain stability during the charging process. Currently, in existing technologies, when wireless chargers limit the position of the device being charged, it is inconvenient to adjust the posture of the device, which adversely affects the user experience. To solve this technical problem, this application provides the following embodiments.

[0020] like Figures 1 to 3 As shown in the embodiment of this application, the wireless charging device 1 includes a wireless charging module 100 and a support mechanism 200. The wireless charging module 100 includes a first housing 110, a second housing 120, a magnetic component 130, and a wireless charging component 140. The second housing 120 is rotatably connected to the first housing 110 and is rotatable along the circumferential direction D1 of the first housing 110. The wireless charging component 140 is connected to either the second housing 120 or the first housing 110 and is used to charge a device. The magnetic component 130 is connected to either the second housing 120 or the first housing 110. A charging area 123 corresponding to the wireless charging component 140 is formed on the second housing 120, and the magnetic component 130 is used to magnetically confine the device to be charged within the charging area 123. The support mechanism 200 is connected to the first housing 110 and is used 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 while 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 apart from the placement surface of the wireless charging device 1, which facilitates the rotation of the wireless charging module 100 and the device to be charged relative to the first housing 110.

[0022] Sometimes, a device needs to adjust its posture while charging. For example, the device can be a mobile phone, and by rotating it relative to the first housing 110, the phone's posture can be adjusted, allowing it to switch between portrait and landscape modes. Another example is a mobile phone, which can be rotated relative to the first housing 110 to straighten a tilted phone.

[0023] By configuring the second housing 120 and the first housing 110 as a rotatable connection, when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first housing 110, the second housing 120 and the device to be charged can rotate synchronously. Thus, there is no sliding friction between the second housing 120 and the device to be charged, or the sliding friction between the second housing 120 and the device to be charged can be reduced. This is beneficial to improving the smoothness of the rotation of the device to be charged, making it easier to adjust the posture of the device to be charged, and improving the user's feel.

[0024] Optionally, the support mechanism 200 can 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 a power source through the support mechanism 200. In some embodiments, the wire 230 can 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 can remain stationary with the device to be charged. This reduces the torsion, tension, and compression forces on the wire 230, thereby reducing the risk of damage to the wire 230.

[0025] Optionally, such as Figures 1 to 3 As shown, the wireless charging assembly 140 may include a transmitting coil 141 and a magnetic shielding sheet 142. The transmitting coil 141 is used to charge the device to be charged, and the magnetic shielding 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 assembly 140 may be disposed on and electrically connected to the circuit board assembly 170. The circuit board assembly 170 can be used to control the charging process of the wireless charging assembly 140 on the device to be charged, and can also be used to assist in heat dissipation of the transmitting coil 141, thereby reducing the temperature of the transmitting coil 141. The circuit board assembly 170 may include at least one PCB board.

[0026] Furthermore, thermal adhesive may be applied to the circuit board assembly 170 to promote heat dissipation of the wireless charging assembly 140.

[0027] Optionally, the circuit board assembly 170 is disposed within the support mechanism 200. For example, the support mechanism 200 includes a base 210 and a support rod 220 connected together, with a first housing 110 connected to the support rod 220, and the support rod 220 supported on the base 210 to support the wireless charging module 100. That is, the base 210 supports the wireless charging module 100 via the support rod 220. The wire 230 can extend from the base 210 through the support rod 220 into the wireless charging module 100. In some embodiments, the circuit board assembly 170 can be disposed within the base 210 to make the wireless charging module 100 thinner and lighter and to reduce the heat generated by the wireless charging module 100. In some 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 within the base 210 and is used to control the charging process of the wireless charging assembly 140 for the device to be charged. The heat dissipation circuit board is disposed within the wireless charging module 100. The wireless charging assembly 140 is disposed on the heat dissipation circuit board and electrically connected to the heat dissipation circuit board. The heat dissipation circuit board is used to assist in the heat dissipation of the transmitting coil 141 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 move the first housing 110 closer to or further away from the base 210. This configuration allows the support mechanism 200 to be folded for easy storage of the wireless charging device 1.

[0029] Optionally, the support rod 220 is configured to be telescopic or foldable, and its height can be adjusted by telescopic or folding movements for easy storage. For example, the support rod 220 includes a first sub-rod and a second sub-rod that are rotatably connected, and the first sub-rod and the second sub-rod can be rotated relative to each other to allow the support rod 220 to be folded or extended.

[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 detached to facilitate charging of the device to be charged. Specifically, the support mechanism 200 is detachably connected to the first housing 110.

[0031] For example, the support mechanism 200 can be detachably connected to the wireless charging module 100 via a snap-fit ​​or magnetic connection. Alternatively, the support mechanism 200 may be equipped with a clip for holding the wireless charging module 100.

[0032] In some embodiments, the wireless charging module 100 includes a battery module (not shown) that can power 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 to power the device to be charged.

[0034] Furthermore, the charging interface is located in the first housing 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 housing 110 relative to the second housing 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 side 104 connecting the front side 102 and the back side 103. In some embodiments, the charging interface is disposed on the peripheral side 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) that matches 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, the first housing 110 is provided with a first electrical contact (not shown), 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 housing 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] Optionally, such as Figures 1 to 3As shown, the support rod 220 includes a main rod 221 and branch rods 222. The main rod 221 is connected to the base 210, and the branch rods 222 are connected between the first housing 110 and the main rod 221. Further, the number of branch rods 222 can be two or more. Different branch rods 222 can support different wireless chargers, thus the wireless charging device 1 can charge different devices (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 configured as a wireless charger for charging watches or headphones. As another example, the wireless charger supported by the branch rods 222 can charge watches or headphones.

[0038] In some embodiments, the support rod 220 is a single, independent rod, which may be a straight rod, a bent rod, etc. In some embodiments, the support rod 220 may include two or more 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 telescopic structure, and its telescopic movement causes the wireless charging module 100 to move closer to or away from the main rod 221. Alternatively, the branch rod 222 is rotatably connected to the main rod 221, and its rotation relative to the main rod 221 causes the wireless charging module 100 to move closer to or away from the main rod 221. For example, by rotating the branch rod 222 relative to the main rod 221, the angle between the branch rod 222 and the main rod 221 can be adjusted between 0° and 180°, thereby allowing the branch rod 222 to 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 the folded state; when the angle between the branch rod 222 and the main rod 221 is between 45° and 135°, the branch rod 222 is in the working state. This design allows for easy folding and storage of the wireless charging device 1 by changing the shape of the support rod 220. The wire 230 can be threaded through the branch rod 222 and the main rod 221, and can deform accordingly when the branch rod 222 rotates relative to the main rod 221.

[0040] Optionally, the branch rod 222 is rotatably connected to the main rod 221, allowing the wireless charging module 100 to rotate around the main rod 221 in the circumference. This arrangement facilitates adjustment of the position of the wireless charging module 100, enabling the wireless charging device 1 to be used in more scenarios. The wire 230 can pass through the branch rod 222 and the main rod 221, and can deform accordingly when the branch rod 222 rotates relative to the main rod 221.

[0041] Optionally, the wireless charging module 100 includes a rear wireless charging component. A rear charging area corresponding to the rear wireless charging component 140 is formed on the first housing 110. The rear wireless charging component is connected to the second housing 120 or the first housing 110 and is used to charge another device located in the rear charging area. With this configuration, the wireless charging module 100 can charge different devices simultaneously, which helps to improve the functionality of the wireless charging module 100.

[0042] Optionally, the wireless charging module 100 includes a rear wireless charging component and a third housing. The third housing has a rear charging area corresponding to the rear wireless charging component. The third housing is rotatably connected to the first housing 110 and is rotatable along the circumferential direction D1 of the first housing 110. The wireless charging component is connected to either the third housing or the first housing 110 for charging the device to be charged. The third housing and the second housing 120 can be connected through the first housing 110. With this configuration, the wireless charging module 100 can charge different devices simultaneously, which improves the functionality of the wireless charging module 100.

[0043] Optionally, another device to be charged can be magnetically confined to the rear charging area by the magnetic component 130, or it can be attracted to the rear charging area by other magnets. Furthermore, the rear charging area and the charging area 123 are located on opposite sides of the wireless charging module 100.

[0044] Optionally, a battery module (not shown) is provided inside the base 210, which is used to power the wireless charging device 1.

[0045] Optionally, such as Figure 2 and Figure 3 As shown, the magnetic assembly 130 includes multiple magnets arranged circumferentially D1 along the first housing 110. Furthermore, the multiple magnets are joined to form a ring structure with a break, which facilitates installation and conforms to installation specifications.

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

[0047] Optionally, such as Figures 1 to 3 As shown, the second housing 120 and the first housing 110 surround to form a receiving space 160. The magnetic component 130 and the wireless charging component 140 are both located in the receiving space 160. A charging area 123 corresponding to the wireless charging component 140 is formed on the side of the second housing 120 away from the receiving space 160.

[0048] Thus, the second housing 120 and the first housing 110 can protect and shield the magnetic component 130 and the wireless charging component 140, which helps to improve the structural stability of the wireless charging module 100.

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

[0050] This configuration allows the second housing 120, the magnetic component 130, and the device to be charged to rotate synchronously when the user adjusts the orientation of the device to be charged along the circumferential direction D1 of the first housing 110. This eliminates sliding friction between the second housing 120 and the device, reduces the resistance of the magnetic component 130 to the rotation of the device, improves the smoothness of rotation, and reduces the effort required by the user. Furthermore, in some embodiments, the wire 230 passes through the first housing 110 and extends to connect with the wireless charging component 140. By connecting the wireless charging component 140 to the first housing 110, the two can remain relatively fixed, reducing the torsional, tensile, and compressive forces on the wire 230 and lowering the risk of damage.

[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 do not contact each other, which can reduce the resistance of the wireless charging component 140 to the rotation of the magnetic component 130.

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

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

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

[0055] Thus, when the user adjusts the posture of the device to be charged along the circumferential direction D1 of the first housing 110, there is no sliding friction between the second housing 120 and the device to be charged, which helps to improve the smoothness of the rotation of the device to be charged, and also helps to reduce the torsion, tension and compression of 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 component 130 and the wireless charging component 140 are both fixedly connected to the first housing 110.

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

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

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

[0060] Thus, when the user adjusts the orientation of the device to be charged along the circumferential direction D1 of the first housing 110, there is no sliding friction between the second housing 120 and the device to be charged, which helps improve the smoothness of the rotation of the device to be charged and also helps reduce 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 helps improve the stability of the wireless charging component 140 in the charging process of the device to be charged.

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

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

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

[0064] Optionally, such as Figure 8 As shown, the wireless charging module 100 includes two elastic conductive contacts 122 and two conductive portions 112 that abut against each other. The two elastic conductive contacts 122 are disposed in one of the second housing 120 and the first housing 110, and the two conductive portions 112 are disposed in the other of the second housing 120 and the first housing 110. The wireless charging assembly 140 is connected to a power source through the two elastic conductive contacts 122 and the two conductive portions 112.

[0065] Specifically, the wireless charging module 100 includes a resilient conductive contact 122 and a conductive portion 112 that are correspondingly abutted and can slide relative to each other. The resilient conductive contact 122 is disposed in the second housing 120 and electrically connected to the wireless charging assembly 140, and the conductive portion 112 is disposed in the first housing 110 and electrically connected to a power source via a wire 230, so that the wireless charging assembly 140 is electrically connected to a power source through the resilient conductive contact 122 and the conductive portion 112. Alternatively, the conductive portion 112 is disposed in the second housing 120 and electrically connected to the wireless charging assembly 140, and the resilient conductive contact 122 is disposed in the first housing 110 and electrically connected to a power source via a wire 230, so that the wireless charging assembly 140 is electrically connected to a power source through the resilient conductive contact 122 and the conductive portion 112.

[0066] The elastic conductive contact 122 and the conductive part 112 can each be provided in two or more forms, such as three or four. Two elastic conductive contacts 122 and two conductive parts 112 can abut against each other in a one-to-one manner. The area of ​​the conductive part 112 for the elastic conductive contact 122 to abut against can be larger than the area of ​​the elastic conductive contact 122 used to abut against the conductive part 112. Therefore, when the second housing 120 rotates relative to the first housing 110, the elastic conductive contact 122 can slide relative to the corresponding conductive part 112 without disengaging from the corresponding conductive part 112.

[0067] For example, the first housing 110 is fixedly disposed relative to the conductive part 112, and the second housing 120 is fixedly disposed relative to the elastic conductive contact 122. The power source can be a mains output or a battery module disposed within the base 210. The wire 230 extends from the power source to connect with the conductive part 112, and the wireless charging component 140 connects with the elastic conductive contact 122, thereby enabling the wireless charging component 140 to connect to the power source.

[0068] By replacing part of the wire 230 with relatively sliding elastic conductive contacts 122 and conductive parts 112, the wire 230 is less likely to be torn or damaged when the second housing 120 rotates relative to the first housing 110. It also prevents the second housing 120 from being hindered from rotating relative to the first housing 110 due to the wire 230 pulling the wireless charging component 140. This helps to improve the service life of the wireless charging device 1 and improve the smoothness of the rotation of the device to be charged.

[0069] Optionally, the flexible conductive contact 122 can be a spring-loaded connector.

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

[0071] In some embodiments, the conductive contact is a non-elastic conductive contact.

[0072] Optionally, such as Figure 8 As shown, one of the two conductive parts 112 is annular and surrounds the other of the two conductive parts 112.

[0073] For example, one of the two conductive portions 112 is annular and the other is circular, with the annular conductive portion 112 surrounding the circular conductive portion 112. Correspondingly, when the second housing 120 rotates relative to the first housing 110, the elastic conductive contact 122 that abuts against the annular conductive portion 112 slides circumferentially along the annular conductive portion 112, with the sliding trajectory surrounding the elastic conductive contact 122 that abuts against the circular conductive portion 112. Furthermore, when the second housing 120 rotates relative to the first housing 110, the elastic conductive contact 122 that abuts against the circular conductive portion 112 undergoes a rotational motion. For another example, both conductive portions 112 may be annular. For another example, both conductive portions 112 may be arc-shaped.

[0074] This configuration allows the second housing 120 to rotate relative to the first housing 110 in one or more revolutions, while also ensuring that the two conductive parts 112 have a sufficient spacing distance and that their structure is compact, thus improving space utilization.

[0075] Optionally, such as Figure 8 As shown, the wireless charging module 100 includes a first plate 121 and a second plate 111 disposed opposite to each other. The first plate 121 is disposed on the second housing 120 and electrically connected to the wireless charging assembly 140, and the second plate 111 is disposed on the first housing 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.

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

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

[0078] Furthermore, the first plate 121 and the second plate 111 can be arranged at intervals, which is beneficial for the heat dissipation of the wireless charging component 140.

[0079] Optionally, the first plate 121 may be the aforementioned heat dissipation circuit board, the aforementioned control circuit board, or the aforementioned circuit board assembly 170. The second plate 111 may be a circuit board, thus facilitating the connection of the conductive part 112 or the elastic conductive contact 122 to the wire 230.

[0080] Optionally, such as Figures 2 to 4As shown, a bearing 151 is provided between the second housing 120 and the first housing 110. The second housing 120 and the first housing 110 can rotate relative to each other through the bearing 151.

[0081] By setting bearing 151, it is beneficial to improve the smoothness of relative rotation between the second housing 120 and the first housing 110, and bearing 151 can also be easy to assemble.

[0082] Optionally, the inner ring of the bearing 151 is fitted onto the first housing 110, and the second housing 120 is fitted onto the outer ring of the bearing 151. This arrangement helps to reduce the size of the first housing 110 while increasing the size of the second housing 120. On the one hand, due to the obstruction of the second housing 120, the first housing 110 is not easily visible from the side where the wireless charging module 100 attaches the device to be charged, which helps to improve the aesthetics. On the other hand, it helps to increase the area on the surface of the first housing 110 where the device to be charged can be placed.

[0083] Optionally, such as 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 enclose a receiving space 160, within which the magnetic assembly 130 and the wireless charging assembly 140 are located. The outer housing 114 is located around 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 disposed within the installation space 115 and fitted onto 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 placing the bearing 151 within the installation space 115, the outer shell 114 can shield and protect the bearing 151, which helps the bearing 151 maintain a stable assembly relationship with the inner shell 113 and the second shell 120, improves the structural stability of the wireless charging module 100, and enhances the aesthetic appearance of the wireless charging module 100.

[0085] Furthermore, the wireless charging component 140 can be installed in the inner housing 113, and a heat dissipation space 1131 can be provided 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 to uniform wall thickness and can reduce the situation of surface collapse caused by uneven shrinkage during molding.

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

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

[0089] Optionally, such as Figures 2 to 4 As shown, the second housing 120 includes a top cover 124 and a middle frame 125. One end of the middle frame 125 has a mounting port (not labeled) through which the magnetic assembly 130 and the wireless charging assembly 140 can be installed. The top cover 124 can be used to seal the mounting port. The charging area 123 is located on the outside of the top cover 124. The other end of the middle frame 125 can extend into the mounting space 115 and abut against the outer ring of the bearing 151. This arrangement facilitates the assembly of the wireless charging module 100. In some embodiments, the magnetic assembly 130 can be fixed to the top cover 124. In other embodiments, the aforementioned fixing plate 143, magnetic assembly 130, and wireless charging assembly 140 can be assembled together on the top cover 124.

[0090] Alternatively, the top cover 124 and the middle frame 125 are connected by adhesive or by clips.

[0091] Optionally, such as Figure 1 , Figures 2 to 4 As shown, the wireless charging module 100 has a front side 102, a back side 103, and a peripheral side 104 connecting the front side 102 and the back side 103. The front side 102 is used to attach the device to be charged. The support mechanism 200 is connected to the first housing 110 on the back side 103. On the outer surface of the wireless charging module 100, the seam 105 between the second housing 120 and the first housing 110 is located on the back side 103 or the peripheral side 104. That is, on the front side 102 of the wireless charging module 100, the second housing 120 can cover the first housing 110, so that the seam 105 between the second housing 120 and the first housing 110 is located on the back side 103 or the peripheral side 104.

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

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

[0094] This design helps to improve the aesthetic appearance of the wireless charging device 1.

[0095] Optionally, such as Figures 5 to 7 As shown, a rolling element 152 is provided between the second housing 120 and the first housing 110. The second housing 120 and the first housing 110 rotate relative to each other via the rolling element 152.

[0096] By incorporating rolling elements 152, the smoothness of relative rotation between the second housing 120 and the first housing 110 is improved, and the rolling elements 152 can also be small in size. For example, the rolling elements 152 can be balls, needle rollers, or cylindrical rollers. There can be multiple rolling elements 152, which can be spaced apart or continuously distributed along the circumferential direction D1 of the first housing 110.

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

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

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

[0100] Optionally, such as Figure 1 , Figure 2 , Figures 7 to 9 As shown, the first housing 110 is provided with stop surfaces 116 distributed along the circumferential direction D1 of the first housing 110. The stop surfaces 116 are used to stop the second housing 120 to prevent the second housing 120 from detaching from the first housing 110. The stop surfaces 116 are distributed at intervals or continuously along the circumferential direction D1 of the first housing 110.

[0101] Specifically, the stop surface 116 is used to restrict the second housing 120 from disengaging from the first housing 110 along the direction of its extension relative to the axis of rotation of the first housing 110.

[0102] In some embodiments, such as Figure 1 and Figure 2As shown, the stop surface 116 is located within the installation space 115 and on the step surface of the aforementioned installation step 1162.

[0103] In other embodiments, such as Figure 9 As shown, a stop plate 1161 is fixed on the inner housing 113, and the stop surface 116 is located on one edge of the stop plate 1161. In some embodiments, such as Figure 8 and Figure 9 As shown, the side of the stop plate 1161 facing away from the stop surface 116 can be used to provide the conductive part 112, that is, the stop plate 1161 can be used as the second plate 111.

[0104] In other embodiments, such as Figure 5 As shown, the aforementioned fixing plate 143 is fixed to the first housing 110, and the stop surface 116 is located on the edge of the fixing plate 143 away from the wireless charging assembly 140.

[0105] Furthermore, the stop surface 116 is used to stop the middle frame 125 to restrict the second housing 120 from disengaging from the first housing 110.

[0106] With this configuration, the stop surface 116 allows the second housing 120 to rotate relative to the first housing 110 while restricting the second housing 120 from disengaging from the first housing 110.

[0107] Optionally, such as Figure 2 and Figure 3 As shown, one of the second housing 120 and the first housing 110 is provided with an elastic protrusion 106, and the other of the second housing 120 and the first housing 110 is provided with a plurality of snap-fit ​​grooves 107 distributed along the circumferential direction D1 of the first housing 110. The plurality of snap-fit ​​grooves 107 are used to snap 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-fit ​​grooves 107 distributed along the circumferential direction D1 of the first housing 110, the plurality of snap-fit ​​grooves 107 being used to engage with the elastic protrusion 106. Alternatively, the first housing 110 is provided with an elastic protrusion 106, and the second housing 120 is provided with a plurality of snap-fit ​​grooves 107 distributed along the circumferential direction of the second housing 120, the plurality of snap-fit ​​grooves 107 being used to engage with the elastic protrusion 106.

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

[0110] By setting the elastic protrusion 106 to engage with the snap-fit ​​groove 107, the relative rotation between the second housing 120 and the first housing 110 can be restricted to a certain extent, thereby helping to maintain the stability of the device to be charged. When the second housing 120 is subjected to force, the second housing 120 and the first housing 110 rotate relative to each other. At the same time, the elastic protrusion 106 can disengage from the original snap-fit ​​groove 107 to allow the second housing 120 and the first housing 110 to rotate relative to each other. As the second housing 120 and the first housing 110 continue to rotate relative to each other, the elastic protrusion 106 will continuously snap into new snap-fit ​​grooves 107 until the second housing 120 and the first housing 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 via an elastic arm, and deformed by the elastic arm to disengage from or engage with the snap-fit ​​groove 107. In some embodiments, the elastic protrusion 106 is formed by bending a metal sheet into a corrugated shape, which creates a deformation space after bending, thereby allowing the metal sheet to deform to disengage from or engage with the snap-fit ​​groove 107.

[0112] Optionally, such as Figure 1 , Figure 9 and Figure 10 As shown, a limiting portion 108 is provided in one of the second housing 120 and the first housing 110. Along the circumferential direction D1 of the first housing 110, a first limiting surface 1091 and a second limiting surface 1092 are provided at intervals in the other housing 120 and the first housing 110. The limiting portion 108 is movably located between the first limiting surface 1091 and the second limiting surface 1092 to limit the relative rotation between the second housing 120 and the first housing 110 by abutting against the first limiting surface 1091 or the second limiting surface 1092.

[0113] This configuration limits the relative rotation angle between the second housing 120 and the first housing 110 to a certain range, thereby reducing the torsional, tensile, and compressive forces on the wire 230 connected to the wireless charging component 140 and lowering 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 circumferential D1 limiting part 108 of the first housing 110 is located in the middle position between the first limiting surface 1091 and the second limiting surface 1092. The second housing 120 can abut against the first limiting surface 1091 and cannot continue to rotate when it rotates 170° forward relative to the first housing 110, and it can abut against the second limiting surface 1092 and cannot continue to rotate when it rotates 170° reverse relative to the first housing 110. Therefore, the torsional, tensile, and compressive forces on the wire 230 are limited.

[0114] Of course, in some embodiments, the second housing 120 and the first housing 110 may not be provided with the limiting part 108, the first limiting surface 1091 and the second limiting surface 1092, so as to allow the second housing 120 and the first housing 110 to rotate relative to each other one or more times.

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

[0116] Optionally, the first limiting surface 1091 and the second limiting surface 1092 can be either a plane or a curved surface.

[0117] Optionally, protrusions are formed on the second housing 120 and the first housing 110, respectively. One of the protrusions on the second housing 120 and the first housing 110 can be a limiting portion 108. The first limiting surface 1091 and the second limiting surface 1092 can be the two sides of the protrusion formed on the other housing 110, or the first limiting surface 1091 and the second limiting surface 1092 can be located on two different protrusions formed on the other housing 110. Further, the first limiting surface 1091 and the second limiting surface 1092 are disposed on the first housing 110, and the limiting portion 108 is formed at the location of the elastic protrusion on the middle frame 125, which facilitates a compact layout on the second housing 120.

[0118] Furthermore, the limiting part 108, the first limiting surface 1091, and the second limiting surface 1092 are configured such that the relative rotation angle between the second housing 120 and the first housing 110 exceeds 90° and is less than 180°. This facilitates the device under charging to adjust its own posture and reduces the force on the wire 230. For example, when the device under charging is a mobile phone, the phone may be tilted when placed on the wireless charging module 100. The user can rotate the phone a certain angle along the circumferential direction D1 of the first housing 110 to straighten it. Then, the user can rotate it 90° in the same direction to switch between portrait and landscape modes. The sum of the two rotation angles will be greater than 90°. If the relative rotation angle between the second housing 120 and the first housing 110 does not exceed 90°, it will be difficult for the device under charging to adjust its own posture. Therefore, in the initial relative position, the angle at which the second housing 120 can rotate forward and backward relative to the first housing 110 can be set to an angle close to 180°, for example, 140° to 155°, or greater than 155° and less than 175°.

[0119] Optionally, such as Figure 1 and Figure 2As shown, the second housing 120 is rotatable relative to the first housing 110 about a first reference axis L1. The support mechanism 200 is rotatably connected to the first housing 110, and both the second housing 120 and the first housing 110 are rotatable relative to the support mechanism 200 about a second reference axis L2. The extending direction of the first reference axis L1 intersects the extending direction of the second reference axis L2. Furthermore, the first reference axis L1 and the second reference axis L2 are perpendicular. That is, the first reference axis L1 is the axis of rotation for the second housing 120 relative to the first housing 110, and the second reference axis L2 is the axis of rotation for the first housing 110 relative to the support mechanism 200.

[0120] This configuration increases the degrees of freedom of movement of the second housing 120, thereby increasing the degrees of freedom of movement of the device to be charged and facilitating the adjustment of the device's posture. Furthermore, when the wireless charging device 1 is operating, the second reference axis L2 is parallel or approximately parallel to the horizontal plane, thus enabling adjustment of the pitch angle of the device to be charged. For example, when the device to be charged is a mobile phone, adjusting the phone's pitch angle makes it easier for the user to view the phone.

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

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

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

[0124] Optionally, such as Figure 1 As shown, 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. Thus, by rotating the support rod 220 relative to the base 210, the pitch angle of the device to be charged can be adjusted. The third reference axis L3 is the axis of rotation 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] Optionally, such as Figure 1As shown, the base 210 includes a first base and a second base rotatably connected. The first base is rotatable relative to the second base about a fourth reference axis L4. The fourth reference axis L4 is the axis of rotation of the first base relative to the second base. Further, the fourth reference axis L4 intersects the second reference axis L2. For example, a 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. This arrangement helps increase the degree of freedom of movement of the device to be charged. In some embodiments, the first base and the second base can rotate relative to each other at least one revolution, enabling the device to be charged to rotate 360° about the fourth reference axis L4.

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

[0127] Optionally, such as 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 housing 110.

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

[0129] Optionally, such as Figures 1 to 4 As shown, the support mechanism 200 is provided with a ball head 201, the first housing 110 is provided with a connecting groove 117 and an elastic member 118 is provided in the connecting groove 117, the ball head 201 can be rotatably extended into the connecting groove 117 and elastically abut against the elastic member 118.

[0130] When the support mechanism 200 and the first housing 110 rotate relative to each other, the ball head 201 can rotate within the connecting groove 117 and slide relative to the elastic member 118. The ball head 201 can be engaged in the connecting groove 117, thereby preventing the support mechanism 200 from disengaging from the first housing 110. The first housing 110 can cover the ball head 201 to improve its appearance. By elastically abutting the ball head 201 against the elastic member 118, the rotational resistance of the ball head 201 within the connecting groove 117 can be increased, preventing the ball head 201 from deviating from its working position due to loosening.

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

[0132] Optionally, such as Figures 1 to 4As shown, the elastic element 118 has a first semi-cylindrical surface 119, and the ball head 201 has a second semi-cylindrical surface 202 that abuts against the first semi-cylindrical surface 119. The generatrix extension directions of both the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are parallel to the second reference axis L2. The parallelism of the generatrix extension directions of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 to the second reference axis L2 also includes the possibility that the generatrix extension directions of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are 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] This configuration allows the support mechanism 200 and the first housing 110 to rotate relative to each other around the second reference axis L2, so as to adjust the posture of the device to be charged. It also restricts the relative movement of the support mechanism 200 and the first housing 110 along the second reference axis L2, which helps to maintain the stability of the support mechanism 200 in supporting 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 facilitate the stable contact between the elastic element 118 and the ball head 201.

[0135] Optionally, such as Figure 1 and Figure 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. 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. Furthermore, the connecting shaft section 204 and the connecting hole 203 are made of metal to improve strength and service life.

[0136] This configuration allows the support mechanism 200 and the first housing 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 interference fit between the connecting shaft segment 204 and the connecting hole 203 can increase friction and limit the relative movement of the support mechanism 200 and the first housing 110 to a certain extent, which is beneficial to the stability of the support mechanism 200 in supporting the wireless charging module 100.

[0137] In some embodiments, such as Figure 11As shown, the first housing 110 is provided with a connecting shaft section 204, and the support 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 within the connecting hole 203. The first housing 110 is provided with a connecting groove 117. The side wall of the connecting hole 203 is provided with a clearance opening 2031, which communicates with the connecting groove 117. The other end of the connecting piece 2042 extends movably through the clearance opening 2031 into the connecting groove 117 and is fixed within the connecting groove 117. This arrangement allows the connecting shaft section 204 to rotate within the connecting hole 203, facilitating the assembly and connection of the support 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 within the connecting hole 203 is an annular structure with an opening. The wire 230 can pass through the annular structure with an opening of the connecting piece 2042 and enter the connecting groove 117, thereby being electrically connected to the wireless charging component 140.

[0139] In summary, this embodiment enables the second housing 120 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 housing 110. This eliminates sliding friction between the second housing 120 and the device to be charged, which helps improve the smoothness of the rotation of the device to be charged and enhances the user's feel. For example, the device to be charged can be a mobile phone. By rotating the device to be charged relative to the first housing 110, the posture of the mobile phone can be adjusted, allowing the mobile phone to switch between portrait and landscape modes, or to straighten the mobile phone from a tilted state.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
