[0032] In related technologies, smartwatches and other electronic devices are becoming increasingly common, and users routinely charge these devices using charging devices. However, the user experience of current charging devices still needs improvement.

[0033] In view of this, please refer to Figures 1 to 10 This application provides a charging device 100 that can improve the user experience.

[0034] Please see Figures 1 to 6 The charging device 100 includes a housing 10, a charging circuit module 20, and a wireless charging module 30. The housing 10 has a receiving cavity 10a, and the charging circuit module 20 is disposed in the receiving cavity 10a.

[0035] The outer casing 10 is recessed inward to form a cavity 10b. For example, the outer casing 10 includes a side wall 12, a top wall 11 connected to the side wall 12, and a bottom wall 16. The top wall 11 is recessed inward toward the receiving cavity 10a to form the cavity 10b. The wireless charging module 30 is rotatably disposed on the outer casing 10 and is at least partially housed in the cavity 10b. The wireless charging module 30 is electrically connected to the charging circuit module 20. The wireless charging module 30 has a first magnetic attachment part 32 for magnetically fixing to an external first electronic device. The first magnetic attachment part 32 is magnetic and can magnetically engage with the first electronic device to supply power to the first electronic device.

[0036] The first electronic device is, for example, a smartwatch, a smart bracelet, or smart glasses.

[0037] The charging circuit module 20 is used to deliver electrical energy. See example. Figures 7 to 10 The outer casing 10 has a first clearance opening 10d, the wireless charging module 30 has a second clearance opening, and the charging device 100 also includes wiring, which passes through the first clearance opening and the second clearance opening and connects the wireless charging module 30 and the charging circuit module 20 respectively.

[0038] As an example, the charging circuit module 20 includes a pin 21 and a power connection circuit. The pin 21 is used to connect to an external power source, and the power connection circuit is disposed in the receiving cavity 10a. The pin 21 is electrically connected to the power connection circuit. Further, the wireless charging module 30 is electrically connected to the pin 21 via the power connection circuit, enabling the wireless charging module 30 to charge the first electronic device. In other embodiments, the charging circuit module 20 includes a built-in power source and a power connection circuit. The wireless charging module 30 is electrically connected to the built-in power source via the power connection circuit, enabling the wireless charging module 30 to charge the first electronic device.

[0039] As an example, the wireless charging module 30 has a circuit board and a transmitting coil. The circuit board is electrically connected to a power connection circuit. When the power connection circuit is energized, the transmitting coil can wirelessly charge the first electronic device.

[0040] Pin 21 is used to connect to a power source to obtain electrical energy. See [example pin 21] for details. Figure 2 The outer casing 10 has a limiting groove 14, and the plug 21 is rotatably mounted on the outer casing 10 so that the plug 21 can be in a retracted state and an extended state. In the retracted state, the plug 21 can be stored in the limiting groove 14. In this way, when the plug 21 is in the retracted state, the space occupied by the charging device 100 can be reduced, making it easier for users to store it in daily life and improving the user experience.

[0041] As an example, pin 21 has an anti-slip layer. For instance, the anti-slip layer can be formed by sandblasting the surface of pin 21, thereby increasing the plug-in stability and user experience of pin 21.

[0042] The housing 10 provides mounting space for structures such as the charging circuit module 20, and serves to shield and protect these structures. It also forms at least a portion of the exterior, making it visible to the user. The shape of the housing 10 is not limited; it can be approximately cuboid, cube, sphere, ellipse, or irregular shape, etc., and this application does not impose any special restrictions. Figure 3 In the case of the outer shell 10, at least a portion of its outer contour is cylindrical.

[0043] For example, please refer to Figure 3 and Figure 4 The wireless charging module 30 can rotate along the first rotation direction S1 to abut against the outer shell 10, so that the wireless charging module 30 is in a first supported state. In the first supported state, the first magnetic part forms a first angle with the horizontal direction. The wireless charging module 30 can rotate along the second rotation direction S2 to abut against the outer shell 10, so that the wireless charging module 30 is in a second supported state. In the second supported state, the first magnetic part forms a second angle with the horizontal direction. The first rotation direction S1 and the second rotation direction S2 are opposite.

[0044] In this way, the outer casing 10 can form a stop structure for the wireless charging module 30, abutting and cooperating with the wireless charging module 30, so that the wireless charging module 30 stops rotating after rotating to a first support state or a second support state. Figure 3 and Figure 4 The wireless charging module 30 can rotate along the first rotation direction S1 until it abuts against the bottom wall of the cavity 10b, so that the wireless charging module 30 is in a first supported state; the wireless charging module 30 can rotate along the second rotation direction S2 until it abuts against the bottom wall of the cavity 10b, so that the wireless charging module 30 is in a second supported state. The wireless charging module 30 can stably support and connect to the first electronic device and charge the first electronic device.

[0045] Further, please refer to Figure 2 The wireless charging module 30 includes a housing 31, and a first magnetic part 32 is disposed on the housing 31. As an example, combined with... Figure 8 and Figure 10 The cover 31 has a second clearance opening 31a. Further, please refer to... Figure 10 The wireless charging module 30 also includes a third magnetic attraction part 34, which is disposed on the cover 31 and located in the installation space, and magnetically adsorbs and cooperates with the outer shell 10, such as magnetically adsorbing and cooperating with the bottom wall of the cavity 10b. In this way, the support stability of the outer shell 10 on the wireless charging module 30 can be improved, and the possibility of the wireless charging module 30 rotating relative to the outer shell 10 can be reduced.

[0046] As an example, please continue reading Figure 1 The sidewall 12 forms two opposing sub-surfaces 121 along the first direction X, and two other opposing sub-surfaces 121 along the second direction Y. The first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other. The first direction X and the second direction Y are located in the horizontal direction. As an example, the maximum length dimension of the wireless charging module 30 along the second direction Y is 48mm, and the maximum length dimension of the wireless charging module 30 along the second direction Y is 50mm.

[0047] Further, please refer to Figure 1 The sub-surface 121 is at least partially curved, and there is a smooth transition between two adjacent sub-surfaces 121 to improve the user's grip and thus enhance the user experience.

[0048] Furthermore, the sidewall 12 is a one-piece molded part, such as the four sub-faces 121 being one-piece molded parts, which can reduce the number of parts.

[0049] Understandably, the wireless charging module 30 can also rotate relative to the housing to other support states to support the first electronic device at other angles.

[0050] For example, please refer to Figure 2 and Figure 5The wireless charging module 30 can rotate to a third supported state, in which the first magnetic suction part 32 is parallel to the horizontal direction. The connecting surface 321 of the first magnetic suction part 32 connects to the first electronic device, and the normal of the first magnetic suction part 32 is perpendicular to the cross-section of the housing 10. The normal of the first magnetic suction part 32 refers to the direction perpendicular to the connecting surface 321. Figure 1 As shown, the cross-section of the outer casing 10 is perpendicular to the first direction X.

[0051] For example, please refer to Figure 2 The pin 21 and the wireless charging module 30 are respectively disposed on the top wall 11 and the bottom wall 16. When the pin 21 is vertically inserted into the power supply in the up-down direction, and the wireless charging module 30 is in the third support state, the connection surface 321 is perpendicular to the first direction X.

[0052] In some embodiments, please refer to Figures 1 to 5 The rotation axis of the wireless charging module 30 passes through itself, and the wireless charging module 30 is symmetrically arranged along the rotation axis. This makes the overall appearance of the charging device 100 more aesthetically pleasing and facilitates the contact and engagement of the wireless charging module 30 with the top wall 11. The rotation angle of the wireless charging module 30 relative to the outer casing 10 is not limited. As an example, the rotation angle of the wireless charging module 30 switching between the first support state and the second support state is 60° to 160°, which is the maximum rotation angle of the wireless charging module 30. For example, it can be 60°, 70°, 80°, 90°, 100°, 120°, 130°, 140°, 150°, or 160°, etc.

[0053] Understandably, the rotation angle of the wireless charging module 30 from the first support state to the second support state is the same as the rotation angle from the second support state to the first support state. That is, the maximum angle of rotation of the wireless charging module 30 along the first rotation direction S1 is equal to the maximum angle of rotation of the wireless charging module 30 along the second rotation direction S2.

[0054] As an example, such as Figures 3 to 5 The wireless charging module 30 rotates at an angle of 90° when switching between the first support state and the second support state.

[0055] Furthermore, the first included angle and the second included angle are equal, for example, both are 45°. The maximum angle by which the wireless charging module 30 rotates from the third support state along the first rotation direction S1 is 45°, and the maximum angle by which the wireless charging module 30 rotates from the third support state along the second rotation direction S2 is 45°.

[0056] As an example, the first included angle is equal to the second included angle, the rotation axis of the wireless charging module 30 passes through itself, and the wireless charging module 30 is symmetrically arranged along the rotation axis.

[0057] The power source for rotating the wireless charging module 30 is not limited; it can be achieved manually or by a power source. This embodiment uses the user manually rotating the wireless charging module 30 as an example. In some embodiments not shown, the charging device 100 further includes a drive assembly, which is driven and connected to the wireless charging module 30 to rotate the wireless charging module 30 to a preset support state. Further, the drive assembly includes a drive member and a transmission member, which are driven and connected to each other. The transmission member is connected to the wireless charging module 30 so that the drive member can transmit driving force to the wireless charging module 30 through the transmission member.

[0058] The charging device 100 provided in this application embodiment has a wireless charging module 30 that can rotate relative to the outer casing 10 and adjust its support angle relative to the outer casing 10. This allows the first magnetic part 32 to connect to the first electronic device at different angles, adapting to various usage scenarios. For example, the connection angle and position of the power supply may differ in different usage environments, and the charging device 100 can be in various positions and angles after connecting to the power supply. The adjustable angle of the wireless charging module 30 improves its adaptability to the environment, enabling it to adapt to different usage environments and enhancing the user experience.

[0059] In some embodiments, please refer to Figures 6 to 10 The charging device 100 includes a rotating assembly 33, with a wireless charging module 30 disposed on the rotating assembly 33. Both ends of the rotating assembly 33 are rotatably connected to the outer casing 10. After rotation, both ends of the rotating assembly 33 can lock circumferentially to the outer casing 10. The power source for unlocking the rotating assembly 33 from the outer casing 10 is not limited and can be achieved manually or by a power source. Understandably, when the wireless charging module 30 is driven to rotate manually or by a power source, the rotating assembly 33 unlocks from the outer casing 10.

[0060] In this way, the wireless charging module 30 can be adjusted to different angles relative to the housing 10. After the rotating component 33 rotates, both ends lock circumferentially with the housing 10, so that the wireless charging module 30 can stably support the first electronic device. Further details can be found in the following section. Figure 10 The cover 31 includes a cover body 311 and a pressure cover 312. The cover body 311 has an installation space; the pressure cover 312 is disposed in the installation space; the pressure cover 312 has an installation groove 312a, and the rotating component 33 is located in the installation groove 312a. In this way, the rotating component 33 can rotate smoothly within the installation groove 312a.

[0061] As an example, the rotating component 33 is mounted in the mounting slot 312a, which improves the rotational synchronization between the wireless charging module 30 and the rotating component 33, reduces the possibility of relative movement between the two, and enhances the user experience.

[0062] In some embodiments, please refer to Figures 8 to 10The rotating assembly 33 includes a first bushing 3321, a second bushing 3322, and an elastic element 3323. The first bushing 3321 is rotatably connected to the outer casing 10, and the second bushing 3322 is rotatably connected to the outer casing 10. The second bushing 3322 is sleeved onto the first bushing 3321 to form a mounting cavity 332a. The elastic element 3323 is disposed in the mounting cavity 332a, and its two ends abut against the first bushing 3321 and the second bushing 3322 respectively, so that the first bushing 3321 abuts against the outer casing 10 axially and locks against the outer casing 10 circumferentially, and the second bushing 3322 abuts against the outer casing 10 axially and locks against the outer casing 10 circumferentially. Here, axial direction refers to the rotational axis of the rotating assembly 33. For example, the elastic element 3323 is a compression spring.

[0063] The first bushing 3321 and the second bushing 3322 can form a mounting cavity 332a, providing a mounting position for the elastic element 3323. The elastic element 3323 is connected to the first bushing 3321 and the second bushing 3322 respectively. When the wireless charging module 30 needs to be rotated, a force is applied to the wireless charging module 30, and the rotating component 33 rotates with the wireless charging module 30. The elastic element 3323 deforms and accumulates elastic potential energy, allowing the first bushing 3321 and the second bushing 3322 to unlock from the outer shell 10. The first bushing 3321 and the second bushing 3322 can rotate relative to the outer shell 10. After the external force is released, the elastic element 3323 deforms and releases elastic potential energy, driving the first bushing 3321 to move axially and abut against the outer shell 10, and driving the second bushing 3322 to move axially and abut against the outer shell 10, thus locking the first bushing 3321 and the second bushing 3322 against the outer shell 10.

[0064] In some embodiments, please refer to Figures 8 to 10 The charging device 100 includes two rotating support seats 15, with recesses 10b spaced apart between them. A first bushing 3321, after rotation, can be locked circumferentially with one of the rotating support seats 15 at both ends, and a second bushing 3322, after rotation, can be locked circumferentially with the other rotating support seat 15 at both ends. As an example, at least one rotating support seat 15 has a first clearance opening, such as... Figure 10 One of the rotating support seats 15 has a first clearance opening 10d.

[0065] When the wireless charging module 30 needs to be rotated, a force is applied to the wireless charging module 30, and the rotating component 33 rotates with the wireless charging module 30. The elastic element 3323 deforms and accumulates elastic potential energy, so that the first bushing 3321 and the second bushing 3322 can unlock from the corresponding rotating support 15. The first bushing 3321 and the second bushing 3322 can rotate relative to the rotating support 15. After the external force is released, the elastic element 3323 deforms and releases elastic potential energy, so that the first bushing 3321 and the second bushing 3322 can be stably connected to the corresponding rotating support 15.

[0066] When the wireless charging module 30 is installed on the housing 10, the first bushing 3321 and the second bushing 3322 can approach each other, allowing them to avoid the rotating support 15, and the elastic element 3323 can accumulate elastic potential energy. When the first bushing 3321 and the second bushing 3322 are aligned with the corresponding rotating support 15, the elastic element 3323 releases its elastic potential energy, allowing the first bushing 3321 and the second bushing 3322 to lock with the corresponding rotating support 15.

[0067] In some embodiments, please refer to Figure 10 The rotating support 15 has a insertion groove 15a; the rotating assembly 33 also includes two adapter shafts 3311, namely a first adapter shaft and a second adapter shaft.
