Detailed Implementation

[0039] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0040] In the description of the embodiments of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0042] This application provides a charger 100. Please refer to... Figure 1 and Figure 2 The charger 100 includes a main body 10 and a support assembly 20. The main body 10 includes a main housing 11 and a first charging module (not shown). The main housing 11 has an inner cavity 10a and an opening 11a. The first charging module is disposed in the inner cavity 10a and is used to charge a first mobile device placed on the main housing 11. The first mobile device may be a smartphone or a tablet computer, etc.

[0043] For example, the first charging module includes a first transmitting coil (not shown), which is used to activate a first receiving coil in the first mobile device in response to a current frequency, thereby charging the first mobile device wirelessly.

[0044] Please see Figure 3 and Figure 4 The support assembly 20 includes a support 21 and a second charging module, which is used to charge a second mobile device located on the support 21. The second charging device can be a smartwatch or a fitness tracker, etc.

[0045] For example, the second charging module includes a second transmitting coil 22, which is used to activate a second receiving coil in the second mobile device in response to a current frequency, thereby charging the second mobile device wirelessly.

[0046] It should be noted that the first charging module and the second charging module can share some electronic components, such as the power supply circuit. In this way, the charger 100 can charge both the first mobile device and the second mobile device, which can reduce the redundancy of electronic components.

[0047] The support assembly 20 is movable relative to the main housing 11 along a first direction. The support assembly 20 has a retracted state and an extended state. In the retracted state, as... Figure 2 As shown, the support assembly 20 is entirely housed within the inner cavity 10a; in the extended state, as... Figure 1As shown, a portion of the support assembly 20 extends out of the main housing 11 through the opening 11a. That is, the support assembly 20 moves along the first direction through the opening 11a to be either retracted or extended from the main housing 11, thus requiring less space for movement. When the support assembly 20 moves from the outside to the inside of the main housing 11 along the first direction, it moves from an extended state to a retracted state; when the support assembly 20 moves from the inside to the outside of the main housing 11 along the first direction, it moves from a retracted state to an extended state.

[0048] The charger 100 provided in this application embodiment has the following characteristics: when the bracket assembly 20 is needed, the bracket assembly 20 extends out of the main housing 11, and the second mobile device can be placed on the bracket 21; when the bracket assembly 20 is not needed, the bracket assembly 20 is stored in the main housing 11. The overall size of the charger 100 is small, which makes it easy to store and has a better appearance. It can meet the user's usage needs and provide a better user experience.

[0049] For example, in one embodiment, the main housing 11 includes a top wall 111 and a side wall 112 connected to each other. The top wall 111 is used to support a first mobile device placed on the main body 10. The side wall 112 is provided with an opening 11a. When the support assembly 20 is extended, the top wall 111 and the support assembly 20 are offset in the height direction, so that the charger 100 can simultaneously place the first mobile device and the second mobile device.

[0050] In some embodiments, please refer to Figure 3 and Figure 4 The charger 100 also includes a locking structure 30, which is disposed in the inner cavity 10a and connects the bracket 21 and the main housing 11. The locking structure 30 is used to lock the bracket assembly 20 in a retracted state, that is, the bracket assembly 20 is almost fixed relative to the main housing 11, so as to minimize the possibility that the bracket assembly 20 will come out of the opening 11a in the retracted state, thereby improving the reliability of the charger 100.

[0051] The locking structure 30 is also used to release the locking of the bracket assembly 20 when an external force presses inward on the bracket assembly 20. The aforementioned external force refers to the force applied by the user or other object that is not generated by the internal structure of the charger 100.

[0052] It should be noted that even when the bracket assembly 20 is locked, it can still be pressed inwards, causing a small displacement. When the bracket assembly 20 is pressed, it moves toward the interior of the main housing 11, thus releasing the lock and allowing it to move in the first direction. In this embodiment, the process of switching the bracket assembly 20 from the extended state to the retracted state, and the process of unlocking it and returning it to the retracted state, both involve the bracket assembly 20 moving toward the interior of the main housing 11. In other words, the user can retract and unlock the bracket assembly 20 simply by pressing it, making the operation very simple and easy to use, and providing a good user experience.

[0053] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 11 The locking structure 30 includes a driving member 31, which applies a force to the bracket assembly 20 toward the outside of the main housing 11. When the locking structure 30 releases the locking of the bracket assembly 20, the driving member 31 drives the bracket assembly 20 to move toward the outside of the main housing 11 through the opening 11a. Thus, after the user presses the bracket assembly 20 to unlock it, the bracket assembly 20 automatically extends under the action of the driving member 31, eliminating the need for the user to manually pull out the bracket assembly 20. This simplifies the use of the charger 100 and improves the user experience.

[0054] In one embodiment, the driving member 31 includes a first magnetic member and a second magnetic member. The first magnetic member is disposed on the bracket 21 and the second magnetic member is disposed on the main housing 11. The first magnetic member and the second magnetic member are disposed opposite to each other along a first direction to generate a repulsive magnetic force.

[0055] For example, in one embodiment, please refer to Figure 3 The driving component 31 includes a spring, one end of which is connected to the bracket 21, and the other end is connected to the main housing 11. The spring can undergo elastic deformation along a first direction. It is understood that when the bracket assembly 20 is pressed towards the interior of the main housing 11, the spring undergoes elastic deformation, accumulating elastic potential energy. After the bracket assembly 20 is unlocked, it extends under the action of elastic force. The spring has a simple structure and low cost.

[0056] The spring can be in the form of a tension spring or a compression spring, etc.

[0057] The number of springs is unlimited; it can be one, two, or more. For example, there are two springs, which are symmetrically arranged on both sides of the bracket 21 to make the bracket assembly 20 move more smoothly.

[0058] In some embodiments, please refer to Figure 3 and Figure 10The locking structure 30 includes a lever 32, which includes a connecting section 323, a first bent portion 321, and a second bent portion 322. The first bent portion 321 and the second bent portion 322 are connected to the two ends of the connecting section 323. The first bent portion 321 is rotatably connected to the main housing 11. For example, the main housing 11 has a pivot hole, and the first bent portion 321 extends into the pivot hole. When the first bent portion 321 rotates, the lever 32 rotates around the center line of the pivot hole.

[0059] Please see Figures 11 to 14 The bracket 21 is provided with a guide groove 21a and a locking groove 21b that are interconnected. The second bent portion 322 is located in the guide groove 21a and can slide relative to the guide groove 21a. In the stored state, the second bent portion 322 hooks onto the locking groove 21b in the first direction away from the opening 11a, which can prevent the bracket 21 from moving, thereby locking the bracket assembly 20.

[0060] For example, such as Figure 9 As shown, the locking groove 21b is V-shaped, with the opening of the V facing outwards from the main housing 11 along the first direction. In the retracted state, the second bend 322 hooks onto the bottom of the V. Of course, the locking groove 21b can also be other recessed shapes, which are not limited here.

[0061] Please see Figure 5 The bracket assembly 20 can move towards the first bending portion 321 under the action of external force, and drive the second bending portion 322 to rotate around the first bending portion 321 and disengage from the locking groove 21b, thereby releasing the locking of the bracket assembly 20. It can be understood that when the bracket assembly 20 moves, the guide groove 21a moves accordingly, and thus generates relative movement with the second bending portion 322, thereby driving the second bending portion 322 to rotate around the first bending portion 321.

[0062] For example, a portion of the guide groove 21a includes a wedge-shaped surface. When the second bend 322 abuts against the wedge-shaped surface and moves relative to it, the wedge-shaped surface causes the displacement of the second bend 322 to have a displacement component perpendicular to the extension direction of the connecting section 323, thereby causing the second bend 322 to rotate around the first bend 321, and the wedge-shaped surface plays a role in reversing direction.

[0063] For example, the bending direction of the first bend 321 relative to the connecting segment 323 is opposite to the bending direction of the second bend 322 relative to the connecting segment 323, so that the first bend 321 will hardly interfere with the bracket 21.

[0064] In some embodiments, please refer to Figures 11 to 14The guide groove 21a includes a first part 21a-1, a second part 21a-2, and a third part 21a-3. Both ends of the first part 21a-1 and both ends of the second part 21a-2 extend towards each other. The first end of both the first part 21a-1 and the first end of both the second part 21a-2 are connected to the third part 21a-3. The third part 21a-3 extends along a first direction. A locking groove 21b connects the second end of the first part 21a-1 and the second end of the second part 21a-2. That is, the first part 21a-1 has a locking groove 21b and the third part 21a-3 at both ends, or the second part 21a-2 has a locking groove 21b and the third part 21a-3 at both ends.

[0065] Please see Figure 13 and Figure 14 When the bracket assembly 20 moves from the retracted state to the extended state, the second bending portion 322 moves from the locking groove 21b through the first part 21a-1 into the third part 21a-3. After the second bending portion 322 leaves the locking groove 21b, the bracket 21 can continue to move until it drives the second bending portion 322 to leave the first part 21a-1 and move along the first direction in the third part 21a-3.

[0066] Please see Figure 11 and Figure 12 When the bracket assembly 20 moves from the extended state to the retracted state, the second bent portion 322 enters the locking groove 21b from the third part 21a-3 via the second part 21a-2. When the bracket 21 moves, it drives the second bent portion 322 to move along the first direction in the third part 21a-3 until it enters the locking groove 21b via the second part 21a-2, thereby locking the bracket assembly 20.

[0067] In this embodiment, during the movement of the bracket assembly 20, the second bending portion 322 moves along the guide groove 21a in a predetermined direction. The direction of movement is definite, which makes the switching between the extended state and the retracted state of the bracket assembly 20 more precise, rapid and efficient.

[0068] In some embodiments, please refer to Figure 7 and Figure 8 The groove depth at the first end of the first part 21a-1 is less than the groove depth at the end of the third part 21a-3 near the first part 21a-1, and a first stepped surface 21a-4 is formed at the junction of the two. The groove depth mentioned above refers to the degree to which the groove 21a is recessed toward the interior of the support 21.

[0069] When the second bend 322 is located in the first part 21a-1, the lever 32 has elastic deformation so that the end of the second bend 322 abuts against the bottom wall of the groove of the first part 21a-1 under the elastic force of the lever 32 itself.

[0070] When the second bend 322 is located in the third part 21a-3, the end of the second bend 322 is spaced apart from the bottom wall of the groove in the third part 21a-3. The first step surface 21a-4 is used to prevent the second bend 322 from moving from the third part 21a-3 to the first part 21a-1. Obviously, the movement of the second bend 322 from the third part 21a-3 to the first part 21a-1 will interfere with the first step surface 21a-4, causing the second bend 322 to tend to enter the second part 21a-2 connected to the third part 21a-3.

[0071] In other words, the second bending part 322 can only enter the third part 21a-3 from the first part 21a-1, but cannot enter the first part 21a-1 from the third part 21a-3 across the first step surface 21a-4. This structure makes the movement direction of the second bending part 322 uniquely determined, and the switching between the extended state and the retracted state of the bracket assembly 20 is more precise, rapid and efficient.

[0072] In some embodiments, please refer to Figure 7 and Figure 9 The groove depth at the second end of the first part 21a-1 is greater than the groove depth at the second end of the second part 21a-2, and a second stepped surface 21a-5 is formed at the junction of the two. The second stepped surface 21a-5 is used to prevent the second bent part 322 from entering the second part 21a-2 from the locking groove 21b. Obviously, the movement of the second bent part 322 from the locking groove 21b to the second part 21a-2 will interfere with the second stepped surface 21a-5, causing the second bent part 322 to tend to enter the first part 21a-1 connected to the locking groove 21b at this point.

[0073] In other words, the second bending part 322 can only enter the locking groove 21b from the second part 21a-2, and cannot cross the second step surface 21a-5 from the locking groove 21b to enter the second part 21a-2. This structure makes the movement direction of the second bending part 322 uniquely determined, and the switching between the extended state and the retracted state of the bracket assembly 20 is more precise, rapid and efficient.

[0074] In some embodiments, please refer to Figure 6The main housing 11 has a receiving groove 11c, and the connecting section 323 is rotatably disposed within the receiving groove 11c. The receiving groove 11c provides clearance space for the rotation of the lever 32. The side wall 112 of the receiving groove 11c is provided with a protrusion 11c-1. When the second bent portion 322 moves along the first portion 21a-1 and / or the second portion 21a-2, the connecting section 323 can abut against the protrusion 11c-1 and have elastic deformation. The protrusion 11c-1 is used to limit the rotation angle range of the lever 32. When the protrusion 11c-1 abuts against the connecting section 323, the rotation of the connecting section 323 is hindered, but the connecting section 323 can undergo elastic deformation so that the second bent portion 322 can continue to move along the second portion 21a-2 without getting stuck.

[0075] In some embodiments, please refer to Figure 6 and Figure 7 One of the main housing 11 and the bracket 21 has a guide groove 11b, and the other has a guide block 211 that mates with the guide groove 11b. The guide groove 11b extends along a first direction, and the guide block 211 extends into the guide groove 11b. The mate between the guide groove 11b and the guide block 211 has a guiding effect, which is beneficial to the smooth movement of the bracket assembly 20.

[0076] For example, there are two guide rail grooves 11b and two guide blocks 211. Each guide block 211 extends into a guide rail groove 11b. The two guide blocks 211 are arranged at intervals on both sides of the bracket 21, and the guide groove 21a is located between the two guide blocks 211.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
