Description

Technical Field

[0001] This invention relates to the field of wireless charging technology, and more specifically, to a wireless charger for watches based on dual-plug data cable storage. Background Technology

[0002] With the continuous advancement of technology, smartwatches have become an indispensable electronic device in people's daily lives, and their convenient functions and stylish appearance are loved by consumers. However, the charging problem of smartwatches has always been a pain point in the user experience. Traditional wired charging methods are not only cumbersome to operate, but also easily affect aesthetics and convenience due to messy cables. To solve this problem, wireless charging technology has emerged and is gradually being widely used in smartwatches. Most existing wireless chargers for smartwatches adopt a fixed design, that is, the charger and the power cord are connected in a fixed way to achieve power transmission. Although this design simplifies the charging process to a certain extent, it still has some shortcomings. For example, when users need to carry the charger out, the fixed power cord is often inconvenient to store, and is prone to cable tangling or damage; at the same time, the fixed connection method also limits the usage scenarios and flexibility of the charger. In addition, as the functions of smartwatches continue to increase and the performance continues to improve, the requirements for charging speed and efficiency are also increasing. Although traditional wireless charging methods have achieved a free and unrestricted charging experience, there is still room for improvement in terms of charging speed and efficiency. Therefore, designing a wireless charger for smartwatches that is both easy to store and highly efficient has become an urgent problem to be solved. Summary of the Invention

[0003] In view of this, the present invention addresses the shortcomings of the prior art by proposing a wireless charger for watches based on dual-plug data cable storage, aiming to solve at least one of the problems mentioned in the background art.

[0004] This invention provides a wireless charger for a watch based on dual-plug data cable storage, comprising: a housing, the top of which is provided with an installation hole, and both sides of the housing are provided with placement holes, the two placement holes being symmetrically arranged, and the bottom of the placement holes being provided with sliding holes communicating with the interior of the housing;

[0005] A rotating base is disposed inside the housing. The bottom of the rotating base is rotatably connected to the bottom wall inside the housing. A data cable is disposed at the bottom of the rotating base, and a PCB board and a heat dissipation cover are disposed at the top of the rotating base.

[0006] The wireless charging module has its connection end fixedly connected to the rotating base via a damping hinge, and the PCB board is electrically connected to the data cable and the wireless charging module respectively.

[0007] In some embodiments, the mounting hole has a circular cross-section, and the mounting hole coincides with the axis of the rotating seat and the housing.

[0008] In some embodiments, the interior of the placement hole is used to place the connector of the data cable, the data cable extends through the sliding hole, and the data cable is slidably connected to the sliding hole.

[0009] In some embodiments, the inner diameter of the sliding hole is larger than the inner diameter of the data cable, and the two sides inside the placement hole are provided with limiting grooves. The two limiting grooves are symmetrically arranged, and the width of the limiting groove matches the thickness of the connector. The width of the placement hole is smaller than the width of the connector.

[0011] In some embodiments, the rotating base has two symmetrical and staggered fixing slots inside, and the data cable passes through the two fixing slots in sequence. The inner diameter of the fixing slot matches the outer diameter of the data cable.

[0012] In some embodiments, the transverse cross-section of the fixing groove is an L-shaped structure.

[0013] In some embodiments, the PCB board is disposed on the top of the rotating base, the mounting end of the bottom of the PCB board is fixedly connected to the top of the rotating base, the heat sink is disposed on the top of the PCB board, and the top of the PCB board is fitted and connected to the bottom of the heat sink.

[0014] In some embodiments, the wireless charging module includes:

[0015] The main body is fixedly connected to the rotating seat via the damping hinge;

[0016] A coil support is disposed inside the main body. The mounting end of the coil support is fixedly connected to the inner wall of the main body. A coil hole is provided in the center of the coil support, and a coil groove is provided in the top of the coil support.

[0017] A coil is disposed inside the coil slot, and the coil is fixedly connected to the inside of the coil slot.

The PCB board is positioned on top of the rotating base, with its bottom mounting end fixedly connected to the top of the rotating base. A heat dissipation cover is also positioned on top of the PCB board, with the top of the PCB board and the bottom of the heat dissipation cover fitting snugly together. This structural design facilitates the timely dissipation of heat generated by the PCB board during operation, preventing overheating that could lead to decreased charging efficiency or device damage, thus ensuring stable and efficient wireless charging. Simultaneously, the bottom of the main body abuts against the top of the heat dissipation cover, further promoting heat conduction and dissipation, and improving the overall heat dissipation performance of the wireless charging device.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] See Figure 1-10 As shown, a wireless charger for a watch based on a dual-plug data cable storage according to an embodiment of this application includes:

[0042] The housing 1 has a mounting hole 2 on its top and placement holes 3 on both sides of the housing 1. The two placement holes 3 are symmetrically arranged, and the bottom of the placement hole 3 has a sliding hole 4 that communicates with the interior of the housing 1.

[0043] A rotating base 5 is disposed inside the housing 1. The bottom of the rotating base 5 is rotatably connected to the bottom wall inside the housing 1. A data cable 6 is disposed at the bottom of the rotating base 5. A PCB board 7 and a heat dissipation cover 8 are disposed at the top of the rotating base 5.

[0044] The wireless charging module has its connection end fixedly connected to the rotating base 5 via a damping hinge 18, and the PCB board 7 is electrically connected to the data cable 6 and the wireless charging module respectively.

[0045] It should be understood that the two connectors 9 of the data cable 6 are respectively placed into the placement holes 3 on both sides of the housing 1, and the connectors 9 are fixed by the limiting grooves 10. The data cable 6 extends out of the housing 1 through the sliding hole 4. The rotating base 5 is set inside the housing 1, and its bottom is rotatably connected to the housing 1. The wireless charging module is fixedly connected to the rotating base 5 through the damping hinge 18, and the angle can be adjusted as needed. The PCB board 7 is electrically connected to the data cable 6 and the wireless charging module respectively to ensure stable current transmission. When the watch is placed on the wireless charging module, the coil 22 inside the wireless charging module generates a magnetic field, which, through the action of the magnet 23, enables the watch to be wirelessly charged. The heat dissipation cover 8 is set on the top of the PCB board 7 to help dissipate heat and prevent the circuit from overheating. At the same time, the watch cover 24 and the coil bracket 19 inside the wireless charging module protect the coil 22 and the magnet 23.

[0046] In some specific embodiments, the mounting hole 2 has a circular cross-section, and the mounting hole 2 coincides with the axis of the rotating seat 5 and the housing 1.

[0047] In some specific embodiments, the interior of the placement hole 3 is used to place the connector 9 of the data cable 6, the data cable 6 extends through the sliding hole 4, and the data cable 6 is slidably connected to the sliding hole 4.

[0048] In some specific embodiments, the inner diameter of the sliding hole 4 is larger than the inner diameter of the data cable 6, and the two sides inside the placement hole 3 are provided with limiting grooves 10. The two limiting grooves 10 are symmetrically arranged, and the width of the limiting groove 10 matches the thickness of the connector 9. The width of the placement hole 3 is smaller than the width of the connector 9.

[0049] It should be understood that the connector 9 of the data cable 6 is placed inside the placement hole 3 and is limited and fixed by the limiting groove 10. The width of the limiting groove 10 matches the thickness of the connector 9 (for example, the width of the limiting groove 10 is 5mm, and the thickness of the connector 9 is also 5mm), ensuring that the connector 9 can be firmly locked in the limiting groove 10 and will not move or fall off at will. The width of the placement hole 3 is smaller than the width of the connector 9 (for example, the width of the placement hole 3 is 8mm, and the width of the connector 9 is 10mm). This design can further limit the lateral movement of the connector 9 and ensure its stable storage. The data cable 6 extends out of the housing 1 through the sliding hole 4. The inner diameter of the sliding hole 4 is larger than the inner diameter of the data cable 6 (for example, the inner diameter of the sliding hole 4 is 6mm, and the inner diameter of the data cable 6 is 4mm). This design allows the data cable 6 to slide freely in the sliding hole 4 while avoiding excessive friction between the data cable 6 and the sliding hole 4. When data cable 6 is needed, the user can gently pull it to slide it out of the sliding hole 4. Due to the presence of the limiting groove 10, the connector 9 will not detach from the placement hole 3 at will; it will only be removed when the user actively pulls it.

[0050] In some specific embodiments, the bottom of the housing 1 is provided with a mounting groove 11 and a connecting hole 12, the bottom of the rotating base 5 is provided with a rotating cover 13, the rotating cover 13 is fixedly connected to the rotating base 5, the rotating cover 13 matches the connecting hole 12, the rotating cover 13 extends into the interior of the mounting groove 11 through the connecting hole 12, a snap-fit ​​groove 14 is provided around the side wall of the mounting groove 11, and a gasket 15 is provided at the end of the mounting groove 11 away from the rotating base 5, the gasket 15 snaps into the snap-fit ​​groove 14.

[0051] In some specific embodiments, the rotating base 5 has two symmetrical and staggered fixing grooves 16 inside, and the data cable 6 passes through the two fixing grooves 16 in sequence. The inner diameter of the fixing groove 16 matches the outer diameter of the data cable 6.

[0052] In some specific embodiments, the transverse cross-section of the fixing groove 16 is an L-shaped structure.

[0053] In some specific embodiments, the PCB board 7 is disposed on the top of the rotating base 5, the mounting end of the bottom of the PCB board 7 is fixedly connected to the top of the rotating base 5, and the heat dissipation cover 8 is disposed on the top of the PCB board 7, with the top of the PCB board 7 and the bottom of the heat dissipation cover 8 being fitted together.

[0054] It should be understood that the rotating base 5 has two symmetrical and staggered fixing slots 16 inside, through which the data cable 6 passes in sequence. The inner diameter of the fixing slot 16 matches the outer diameter of the data cable 6 (for example, the inner diameter of the fixing slot 16 is 4mm, and the outer diameter of the data cable 6 is also 4mm), ensuring that the data cable 6 can be tightly fixed in the fixing slot 16 and will not move or fall off at will. The cross-section of the fixing slot 16 is L-shaped, which further enhances the fixing effect on the data cable 6. The L-shaped fixing slot 16 can better wrap the data cable 6, preventing it from falling out of its fixed position due to shaking or pulling during use. The PCB board 7 is set on the top of the rotating base 5, and its bottom mounting end is fixedly connected to the top of the rotating base 5. This design ensures the stability of the PCB board 7 on the rotating base 5, while facilitating circuit layout and connection. The heat sink 8 is set on the top of the PCB board 7, and its bottom is attached to the top of the PCB board 7. The function of the heat sink 8 is to help the PCB board 7 dissipate heat and prevent the circuit from being damaged due to overheating. For example, when the wireless charging module is working, the PCB board 7 will generate a certain amount of heat. The heat sink 8 can conduct the heat away through its material (such as metal) to maintain the normal operating temperature of the circuit.

[0055] In some specific embodiments, the wireless charging module includes:

[0056] The main body 17 is fixedly connected to the rotating seat 5 via the damping hinge 18;

[0057] A coil support 19 is disposed inside the main body 17. The mounting end of the coil support 19 is fixedly connected to the inner wall of the main body 17. A coil hole 20 is provided in the center of the coil support 19, and a coil groove 21 is provided in the top of the coil support 19.

[0058] The coil 22 is disposed inside the coil slot 21, and the coil 22 is fixedly connected to the inside of the coil slot 21;

[0059] A magnet 23 is disposed inside the coil hole 20, and the magnet 23 is fixedly connected to the inner wall of the coil hole 20;

[0060] A watch cover 24 is disposed on the top of the coil 22, and the bottom of the watch cover 24 is fixedly connected to the main body 17;

[0061] The coil 22 is electrically connected to the PCB board 7 and the data line 6, respectively.

[0062] In some specific embodiments, the bottom of the main body 17 abuts against the top of the heat dissipation cover 8, and the depth of the mounting hole 2 matches the thickness of the main body 17.

[0063] It should be understood that the main body 17 of the wireless charging module is fixedly connected to the rotating base 5 via a damping hinge 18. The function of the damping hinge 18 is to allow the main body 17 to adjust its angle within a certain range (e.g., 0° to 90°), while providing appropriate resistance to ensure that the main body 17 remains stable after adjustment. This design allows the wireless charging module to adjust its angle according to the charging needs of the watch, improving the flexibility and convenience of charging.

[0064] A coil support 19 is located inside the main body 17, with its mounting end fixedly connected to the inner wall of the main body 17. A coil hole 20 is located at the center of the coil support 19, and a coil groove 21 is located at its top. The function of the coil support 19 is to fix and support the coil 22, while providing a stable working environment for the coil 22. The coil 22 is located inside the coil groove 21 and is fixedly connected to it. The coil 22 is the core component of wireless charging; when current passes through the coil 22, it generates an alternating magnetic field. This magnetic field, through the action of the magnet 23, transfers energy to the watch's receiving coil, achieving wireless charging. The magnet 23 is located inside the coil hole 20 and is fixedly connected to the inner wall of the coil hole 20. The function of the magnet 23 is to enhance the magnetic field generated by the coil 22 and help the watch accurately align with the charging area. For example, when the watch is close to the wireless charging module, the magnetic force of the magnet 23 can attract the metal parts of the watch, ensuring that the watch's receiving coil is aligned with the coil 22, improving charging efficiency. A watch cover 24 is located on top of the coil 22, and its bottom is fixedly connected to the main body 17. The watch cover 24 protects the coil 22 and magnet 23, preventing dust, moisture, or other foreign objects from entering the wireless charging module. Simultaneously, the watch cover 24 serves as the watch's contact surface, providing a flat charging area. The coil 22 is electrically connected to the PCB board 7 and the data cable 6. The PCB board 7, as the core of the circuit, is responsible for controlling current transmission and the wireless charging process. The data cable 6 connects to an external power source or device, providing power to the wireless charging module. When the data cable 6 is connected to an external power source, current is transmitted through the PCB board 7 to the coil 22. The coil 22 generates an alternating magnetic field, which, with the assistance of the magnet 23, transfers energy to the watch's receiving coil, achieving wireless charging.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
