[0055] Existing smartwatches are usually charged by means of a charging dock. A charging dock is a charging device specifically designed for smartwatches and usually has a small size to fit the size of the watch. There will be metal contacts on the base, and these metal contacts match the contacts on the back of the watch and make contact with the metal contacts on the back of the smartwatch during charging. Place the smartwatch on the charging dock and ensure that the metal contacts on the back of the watch are accurately aligned with the contacts on the charging dock. Sometimes it may be necessary to slightly adjust the position of the watch to ensure good contact. Once the contacts are aligned, the charging dock will transmit power to the watch through the contacts. The charging dock is connected to a power adapter through a charging cable, and the adapter is then plugged into a power socket to supply power.

[0056] In order to enable a smart watch to maintain a good connection with a charging stand, a magnetic attraction structure is usually provided on the metal contacts of the charging stand and the metal contacts of the smart watch. Through this magnetic attraction structure, the smart watch is adsorbed on the charging stand to prevent the smart watch and the charging stand from falling off and causing damage. However, the applicant found in the research that although the method of connecting the charging stand and the smart watch by setting the magnetic attraction structure can set the smart watch and the charging stand together to a certain extent, its adsorption force is usually relatively small, and during the charging process, the smart watch is still likely to fall off the charging stand, causing damage to the smart watch. At the same time, since the magnetic attraction structure is provided at the metal contacts of the smart watch and the charging stand, on the one hand, the magnetic attraction structure will occupy the internal space of the smart watch, which is not conducive to the thin and light design of the smart watch. On the other hand, the magnetic attraction structure often causes electromagnetic interference to the smart watch and the charging stand, reducing the charging effect.

[0057] In view of this, the applicant has proposed a new charging stand. The charging stand proposed in the embodiment of the present application forms a receiving space for accommodating the smart watch by providing an upper cover on the base, and a magnetic attraction part is provided at the edges of the upper cover and the base, and the magnetic attraction part adsorbs the upper cover and the base together. During charging, only need to place the smart watch on the base, cover the smart watch with the upper cover, and the magnetic attraction parts at the edges of the upper cover and the base will suck the upper cover and the base together, firmly enclosing the smart watch in the receiving space formed by the upper cover and the base. In this way, the connection between the smart watch and the base is more stable and will not fall off easily. At the same time, by setting the magnetic attraction part at the edges of the base and the upper cover, the electromagnetic interference caused by the magnetic attraction part to the charging circuit board on the base and the smart watch is avoided, and the stability of charging the smart watch is improved. The charging stand proposed in the embodiment of the present application can not only charge the smart watch, but also charge any other electronic device that matches the charging stand, which is not limited in the present application.

[0058] Such as Figure 1 、 Figure 2A and Figure 2BAs shown in the figure, a structural diagram of the charging stand 100 proposed in the embodiment of the present application is shown. The charging stand 100 proposed in the embodiment of the present application includes an upper cover 10 and a base 20. A first connecting portion 16 and a first magnetic attraction portion 13 are spaced apart on one side edge of the upper cover 10. A second connecting portion 26 is provided at a position on one side edge of the base 20 opposite to the first connecting portion 16, and a second magnetic attraction portion 23 is provided at a position opposite to the first magnetic attraction portion 13. A charging interface 27 is provided on one surface of the base 20. The upper cover 10 and the base 20 are rotatably connected through the first connecting portion 16 and the second connecting portion 26, and the first magnetic attraction portion 13 and the second magnetic attraction portion 23 magnetically cooperate to magnetically attract and connect the upper cover 10 and the base 20. When the upper cover 10 and the base 20 are magnetically attracted and connected through the first magnetic attraction portion 13 and the second magnetic attraction portion 23, a receiving space is formed between the base 20 and the upper cover 10, and the receiving space is used to place the device to be charged. The base 20 charges the device to be charged through the charging interface 27.

[0059] As Figure 1 shown in the figure, the connection manner between the upper cover 10 and the base 20 is shown. The shapes of the upper cover 10 and the base 20 are adapted to the shape of the smart watch, and can be disc-shaped, square-shaped, or other shapes, which are not limited in the present application. The base 20 forms the basis for charging the device to be charged, and a charging circuit board 28 and a charging interface 27 are provided thereon. The external power supply is connected to the base 20 through a power adapter to realize charging of the device to be charged.

[0060] In order to set the upper cover 10 and the base 20 together, as shown in FIG. 2, a first connecting portion 16 and a first magnetic attraction portion 13 are spaced apart on one side edge of the upper cover 10. Herein, one side edge of the upper cover 10 refers to the side opposite to the base 20 at the edge position of the upper cover 10. When the upper cover 10 is circular, the first connecting portion 16 can be set at any position on the edge of the upper cover 10. When the upper cover 10 is square, it can be on the edge of any side of the upper cover 10. The first connecting portion 16 is mainly used to connect with the base 20. A first magnetic attraction portion 13 is provided on one side edge of the upper cover 10. The first magnetic attraction portion 13 is mainly used to magnetically attract the upper cover 10 and the base 20 together, so that the upper cover 10 and the base 20 can be relatively opened or closed. In order to improve the closing effect between the upper cover 10 and the base 20, usually the first connecting portion 16 and the first magnetic attraction portion 13 are relatively arranged on the edge of the upper cover 10 and are in symmetric positions with each other. Of course, they can also be arranged at other positions according to needs, as long as the upper cover 10 and the base 20 can be better magnetically attracted together. The first magnetic attraction portion 13 can be multiple magnetic attraction points or one magnetic attraction point. As shown in FIG. 2, two magnetic attraction points can be provided on the edge of the upper cover 10 to jointly form the first magnetic attraction portion 13.

[0061] Continuing to refer to FIG. 2, corresponding to the relevant settings of the upper cover 10, a second connecting portion 26 is provided at a position on one side edge of the base 20 opposite to the first connecting portion 16, and a second magnetic attracting portion 23 is provided at a position opposite to the first magnetic attracting portion 13. The second connecting portion 26 is mainly used to cooperate with the first connecting portion 16 to rotatably connect the upper cover 10 and the base 20 together. It should be noted that in the embodiments of the present application, for the convenience of description, the connecting mechanism between the upper cover 10 and the base 20 is divided into the first connecting portion 16 and the second connecting portion 26. It should be noted that the first connecting portion 16 and the second connecting portion 26 can also be combined to form a connecting mechanism to connect the upper cover 10 and the base 20 together, as long as it can connect the upper cover 10 and the base 20 and enable the upper cover 10 and the base 20 to relatively rotate through this connecting structure, the division of names does not constitute any limitation.

[0062] Meanwhile, between the first connecting portion 16 and the upper cover 10, they can be integrally formed, with a connecting structure integrally formed at the edge of the upper cover 10. The first connecting portion 16 and the upper cover 10 can also be separately provided, that is, the first connecting portion 16 and the upper cover 10 can be separately arranged and connected together by screws or other mechanisms. Similarly, between the second connecting portion 26 and the base 20, they can be integrally formed, with a connecting structure integrally formed at the edge of the base 20, or they can be separately provided, that is, the second connecting portion 26 and the base 20 can be separately arranged. As shown in FIG. 2, in the embodiments of the present application, the first connecting portion 16 and the upper cover 10 are separately arranged, and the second connecting portion 26 and the base 20 are also separately arranged.

[0063] The second magnetic attracting portion 23 is provided at a position on the edge of the base 20 corresponding to the first magnetic attracting portion on the upper cover 10, so as to cooperate with the first magnetic attracting portion 13 to attract and close the other edge of the upper cover 10 and the base 20 together. Similarly, the second magnetic attracting portion 23 can be provided with multiple magnetic attracting points or one magnetic attracting point. As shown in FIG. 2, two magnetic attracting points can be provided on the edge of the upper cover 10 to jointly form the first magnetic attracting portion 13.

[0064] On the inner surface of the base 20, a charging interface 27 is further provided, and this charging interface 27 is used to contact the charging interface 27 on the device to be charged, so as to realize charging of the device to be charged.

[0065] When it is necessary to charge the device to be charged, only need to push one side edge of the upper cover 10 in the opening direction to separate the first magnetic attraction part 13 and the second magnetic attraction part 23, open the upper cover 10, and place the device to be charged on the base 20; then push one side edge of the upper cover 10 in the closing direction to make the upper cover 10 rotate relative to the base 20 through the first connecting part 16 and the second connecting part 26. When the first magnetic attraction part 13 and the second magnetic attraction part 23 are close to each other, the upper cover 10 and the base 20 are magnetically attracted and connected through the first magnetic attraction part 13 and the second magnetic attraction part 23. The device to be charged is received in the receiving space formed between the base 20 and the upper cover 10, and the base 20 charges the device to be charged through the charging interface 27.

[0066] In the embodiment of the present application, one side of the base 20 and the upper cover 10 is connected through a connecting part, and the other side is connected through a magnetic attraction part. When the upper cover 10 and the base 20 are closed, a receiving space for accommodating the smart watch is formed, and the magnetic attraction part adsorbs the upper cover 10 and the base 20 together. During charging, the device to be charged can be firmly enclosed in the receiving space formed by the upper cover 10 and the base 20. In this way, the connection between the device to be charged and the base 20 is more stable and will not fall off easily. At the same time, the magnetic attraction part is arranged at the edges of the base 20 and the upper cover 10, avoiding the electromagnetic interference caused by the magnetic attraction part to the charging circuit board on the base 20 and the device to be charged, and improving the stability of charging the device to be charged.

[0067] In order to better realize the connection between the upper cover 10 and the base 20, Figure 3A and Figure 3B shows the connection structure diagram between the first connecting part 16 and the second connecting part 26. As Figure 3A and Figure 3B shown, the first connecting part 16 includes a connecting through hole 161; the second connecting part 26 includes a connecting bracket 261 and a connecting shaft 262; the connecting shaft 262 passes through the connecting through hole 161 of the first connecting part 16 and is fixedly connected to the connecting bracket 261 at both ends, and the first connecting part 16 is rotationally connected to the second connecting part 26 around the connecting shaft 262.

[0068] As Figure 3A and Figure 3BAs shown, the first connecting portion 16 includes a connecting through hole 161. The connecting through hole 161 is provided on one side of the first connecting portion 16. The connecting through hole 161 is used to cooperate with the second connecting portion 26 for connection. The other side of the first connecting portion 16 is used to be arranged together with the upper cover 10. The second connecting portion 26 includes a connecting bracket 261 and a connecting shaft 262. One side of the connecting bracket 261 is used to be fixedly connected to the base 20, and the other side is provided with a connecting shaft 262 for cooperating with the first connecting portion 16 for connection. Fixing portions may be respectively provided at both ends of the connecting bracket 261. Both ends of the connecting shaft 262 are respectively connected to the fixing portions and are fixedly arranged together with the connecting bracket 261. As Figure 3A and 3B shown, during assembly, first, place the position of the connecting through hole 161 of the first connecting portion 16 between the fixing portions at both ends of the connecting bracket 261. Then, one end of the connecting shaft 262 passes through the fixing portion at one end of the connecting bracket 261 and the connecting through hole 161 of the first connecting portion 16, and is connected to the fixing portion at the other end of the connecting bracket 261. By fixing both ends of the connecting shaft 262 on the connecting bracket 261 respectively, the connecting through hole 161 of the first connecting portion 16 can rotate relative to the connecting shaft 262, thereby realizing the rotational connection between the first connecting portion 16 and the second connecting portion 26. By this connection method, the structure is simple, the operation is convenient, and the cost can be reduced.

[0069] Further, in order to increase the convenience of connection between the first connecting portion 16 and the second connecting portion 26 and the opening and closing effect between the upper cover 10 and the base 20, the embodiment of the present application also proposes a connection method between the upper cover 10 and the base 20, as Figure 3A 、 Figure 3B and Figure 4 shown, a cam 264 is fixedly provided at one end of the connecting shaft 262. The cam 264 is fixedly connected to the connecting bracket 261. An idler wheel 265 and a first spring 263 are movably sleeved on the connecting shaft 262 at a position adjacent to the cam 264. One end of the first spring 263 abuts against the idler wheel 265 for pressing the cam 264 and the idler wheel 265 against each other. The outer surface of the idler wheel 265 is engaged with the connecting through hole 161 of the first connecting portion 16. When the idler wheel 265 rotates relative to the cam 264 around the connecting shaft 262 driven by the first connecting portion 16, the idler wheel 265 slides along the axial direction of the connecting shaft 262 in the connecting through hole 161 under the extrusion of the cam 264.

[0070] As Figure 3AAs shown, a cam 264 is fixedly arranged at one end of a connecting shaft 262. One end of the connecting shaft 262 is fixedly connected to a fixing portion at one end of a connecting bracket 261 through the cam 264. A concave cam 265 and a first spring 263 are also sleeved on the connecting shaft 262 at a position adjacent to the cam 264. One end of the first spring 263 abuts against the concave cam 265 and is used to squeeze the cam 264 and the concave cam 265. The concave cam 265 is used in cooperation with the cam 264. The outer surface of the concave cam 265 is engaged with a connecting through hole 161 of the first connecting portion 16. When the first connecting portion 16 rotates, it can drive the concave cam 265 to rotate together. As Figure 4 shown, the specific structures of the cam 264 and the concave cam 265 are shown. The opposite end surfaces of the cam 264 and the concave cam 265 are of a curved surface structure.

[0071] As Figure 4 shown, the concave and convex cam structure adopted in the embodiment of the present application is a mechanical transmission structure, which is composed of the engagement of the concave cam 265 and the cam 264. This structure is used to achieve specific motion or power transmission in mechanical design. The surface of the cam 264 has protruding parts. The cam 264 can rotate according to a specific contour. During the rotation, these protruding parts will push the concave cam 265 to follow the movement of other mechanical components, such as the connecting shaft 262, so as to achieve a predetermined motion law. The concave cam 265 is a component that cooperates with the cam 264 and is usually designed to be concave so as to be adapted to the protruding parts of the cam 264. The concave cam 265 is movable. The concave cam 265 is sleeved on the connecting shaft 262, and its outer wall is engaged with the inner wall of the connecting through hole 161 of the first connecting portion 16 and can rotate with the rotation of the first connecting portion 16. The inner wall of the concave cam 265 is sleeved on the connecting shaft 262 and moves along the axis direction of the connecting shaft 262 under the push of the cam 264. During the movement of the concave cam 265, the first spring 263 exerts a squeezing force on the concave cam 265, so that the concave cam 265 and the cam 264 are always in an abutting state during the relative movement.

[0072] During the rotation of the cam 265 along with the first connecting portion 16, as it comes into contact with different curved surface positions of the cam 264, the cam 264 will generate torques of different degrees on the first connecting portion 16 in the direction perpendicular to the axis of the connecting shaft 262, which can assist in the opening and closing of the upper cover 10. The mating relationship between the cam 265 and the cam 264 includes several states. When the surfaces of the cam 265 and the cam 264 are completely fitted, that is, when the concave portion of the cam 265 corresponds to the convex portion of the cam 264, there will be no torque between them, and at this time, the two are in a balanced state. However, if they move further, an opposite acting force will be generated; when the concave portion of the cam 265 and the convex portion of the cam 264 are completely misaligned, that is, when the convex portion of the cam 265 corresponds to the convex portion of the cam 264, at this time, the two are also in a balanced state, but if they move further, the same acting force will be generated. As Figure 5 shown, the relative states of the first connecting portion 16 and the second connecting portion 26 under the action of the cam 265 and the cam 264 are shown.

[0073] In state (a), the curved surfaces of the cam 265 and the cam 264 are in a relatively misaligned state. The cam 264 generates a torque on the cam 265 in the opening direction of the upper cover 10 (i.e., the arrow direction), making it easier to open the upper cover 10. When pushing the upper cover 10 to drive the first connecting portion 16 to gradually close, in state (b), it is at the torque balance point position, that is, the cam 265 is at the maximum position pushed by the cam 265, that is, the first spring 263 is at the most tightened position. When the first connecting portion 16 is further closed, the cam 264 generates a torque on the cam 265 in the closing direction of the upper cover 10, making it easier to close the upper cover 10; when the first connecting portion 16 is further opened, the cam 264 generates a torque on the cam 265 in the opening direction of the upper cover 10, making it easier to open the upper cover 10. When pushing the upper cover 10 to drive the first connecting portion 16 to gradually close, in state (c), the upper cover 10 and the base 20 are mutually latched and at the installation angle. At this time, the cam 264 continues to generate a torque on the cam 265 in the closing direction of the upper cover 10, making the upper cover 10 better closed on the base 20. That is, in this state, the upper cover 10 and the base 20 are not only attracted to each other by the magnetic attraction between the first magnetic attraction portion 13 and the second magnetic attraction portion 23, but also through the torque of the cam 264 on the cam 265 in the closing direction of the upper cover 10, making the upper cover 10 and the base 20 better closed, and making the device to be charged not easily fall off. State (d) is the self-locking state of the cam 264 and the cam 265, that is, the curved surfaces of the cam 264 and the cam 265 are mutually fitted and do not generate extrusion with each other, that is, the cam 264 will not generate any torque on the cam 265.

[0074] Through the cam 265 and the cam 264 provided by the embodiments of the present application, corresponding torques are provided for the upper cover 10 during the opening and closing processes, making the opening and closing of the upper cover 10 more convenient. At the same time, when the upper cover 10 and the base 20 are in a closed state, the cam 265 and the cam 264 can provide a torque for the upper cover 10 in the closing direction, so that the upper cover 10 can be more firmly closed on the base 20, avoiding being opened during use and causing the dropping and damage of the device to be charged.

[0075] Further, in order to limit the rotation angle between the upper cover 10 and the base 20, as Figure 3A and Figure 3B shown, in the embodiments of the present application, a rotation stop post 266 is provided on the inner surface of one end of the connection bracket 261, and a rotation stop groove 166 is provided on the outer surface of one end of the first connection portion 16; when the first connection portion 16 and the second connection portion 26 are rotatably connected through the connection through hole 161 and the connection shaft 262, the rotation stop post 266 is located in the rotation stop groove 166, and the rotation stop groove 166 and the rotation stop post 266 cooperate to limit the relative rotation angle between the first connection portion 16 and the second connection portion 26.

[0076] As Figure 3A shown, a rotation stop post 266 is provided on the inner surface of one end of the connection bracket 261. The rotation stop post 266 is a convex structure, which can be provided at one end of the connection bracket 261 away from the cam 264, or can be provided at the same end as the cam 264. Cooperating with the rotation stop post 266, a rotation stop groove 166 is provided on the outer surface of one end of the first connection portion 16. The rotation stop groove 166 is formed by inward depression on the surface of one end of the first connection portion 16, and both ends thereof have stop points for limiting the maximum and minimum rotation angles.

[0077] When the first connection portion 16 and the second connection portion 26 are arranged together, the rotation stop post 266 is located in the rotation stop groove 166. When the first connection portion 16 rotates relative to the second connection portion 26, the rotation stop post 266 moves in the rotation stop groove 166. When it moves to the stop point position of the rotation stop groove 166, the rotation angles of the first connection portion 16 and the second connection portion 26 are restricted and their continuous rotation is restricted. In the embodiments of the present application, it can be defined that the first connection portion 16 and the second connection portion 26 can only rotate between 0° and 90°. It should be noted that the rotation stop groove 166 can also be provided on the connection bracket 261, and the rotation stop post 266 can also be provided on the first connection portion 16, as long as they are arranged relatively, which is not limited in the present application.

[0078] In the embodiment of the present application, by providing the anti-rotation post 266 and the anti-rotation groove 166, it is possible to prevent the opening and closing angle between the upper cover 10 and the base 20 from being too large, which may cause the connection part between the upper cover 10 and the base 20 to break, thereby improving the service life.

[0079] Further, in order to improve the usability of the charging stand 100, as Figure 2A and 2B shown, in the embodiment of the present application, the upper cover 10 includes a first upper housing 11 and a first lower housing 12; the first upper housing 11 and the first lower housing 12 are in a circular ring shape and are snap-fitted to each other, forming a first accommodation chamber inside, and the first magnetic attraction part 13 is arranged in the first accommodation chamber.

[0080] As Figure 2A and 2B shown, the first upper housing 11 and the first lower housing 12 are in a circular ring shape, so that when charging the device to be charged, the time can be continuously viewed or the charging status of the device to be charged can be viewed in real time through the circular ring-shaped hollow. The first upper housing 11 and the first lower housing 12 can be respectively provided with snap-fit structures and snap-fitted to each other by a snap-fit method; or they can be fixed by setting threaded holes and using threads. When the first upper housing 11 and the first lower housing 12 are snap-fitted to each other, a first accommodation chamber is formed inside. In order to better fix the first magnetic attraction part 13 and prevent the first magnetic attraction part 13 from slipping, the first magnetic attraction part 13 can be arranged in the accommodation chamber. As Figure 2A shown, the first magnetic attraction part 13 includes a first magnet 131, and a first limiting hole 132 is arranged on the first lower housing 12. By arranging the first magnet 131 in the first limiting hole 132, the first magnetic attraction part 13 can be firmly fixed in the accommodation chamber. In this way, the structure is compact, and at the same time, the dropping of the first magnetic attraction part 13 is avoided, improving the service life of the product.

[0081] Further, in order to conveniently place the device to be charged on the base 20 and prevent the user from placing it incorrectly, as Figure 2A and Figure 2B shown, the embodiment of the present application also provides an anti-fooling mechanism on the edge of the base 20. Specifically, a first limiting part 24 and a second limiting part 25 are respectively arranged at intervals on one side edge of the base 20; a receiving space is formed between the first limiting part 24 and the second limiting part 25 for placing the device to be charged; the second connecting part 26 is arranged on the first limiting part 24, and the second magnetic attraction part 23 is arranged on the second limiting part 25.

[0082] As Figure 2AAs shown in the figure, on one side edge of the base 20, a first limiting portion 24 and a second limiting portion 25 are convexly formed upward. The setting interval and shape of the first limiting portion 24 and the second limiting portion 25 are adapted to the device to be charged, which can play an anti-misoperation role. When the user charges, there is no need to align the charging contact 271 of the device to be charged with the charging contact 271 on the charging base 100 anymore. Instead, the device to be charged can be directly placed on the base 20 to achieve the alignment of the charging contact of the device to be charged with the charging contact on the charging base 100. At the same time, the first limiting portion 24 and the second limiting portion 25 and the base 20 can be integrally formed or separately arranged, which is not limited here.

[0083] At the same time, in order to make the structure of the charging base 100 more compact, in the embodiment of the present application, the second connecting portion 26 is arranged on the first limiting portion 24, and the second magnetic attraction portion 23 is arranged on the second limiting portion 25, making the structure of the charging base 100 more compact.

[0084] In order to make the structure of the charging base 100 more compact, in the embodiment of the present application, as Figure 2A and Figure 2B shown, the base 20 includes a second upper shell 21 and a second lower shell 22; the second upper shell 21 and the second lower shell 22 are buckled together to form a second accommodation chamber inside, and a circuit board 28 is arranged in the second accommodation chamber; the charging interface 27 penetrates through the second upper shell 21 and is electrically connected to the circuit board 28.

[0085] As Figure 2A shown, the second upper shell 21 and the second lower shell 22 can be buckled together by means of snap connection or screw connection to form a second accommodation chamber. Inside the second accommodation chamber, the circuit board 28 can be placed. The circuit board 28 is electrically connected to the charging interface 27. The charging interface 27 includes a charging contact 271. A charging through hole 272 is arranged on the second upper shell 21. One end of the charging contact 271 is electrically connected to the circuit board 28, and the other end penetrates through the charging through hole 272 and is electrically connected to the device to be charged.

[0086] As Figure 2A and Figure 2B shown, on the second upper shell 21 and the second lower shell 22, at the position corresponding to the second limiting portion 25, a second magnetic attraction portion 23 is arranged. The second magnetic attraction portion 23 includes a second magnet 231 and a second limiting hole 232. The second limiting hole 232 is arranged on the second upper shell 21, and the second magnet 231 is arranged in the second limiting hole 232. Through the mutual buckling between the second upper shell 21 and the second lower shell 22, the second magnetic attraction portion 23 is fixed in the second accommodation chamber.

[0087] Meanwhile, in order to enable the charging base 100 to maintain balance when the upper cover 10 is opened, in the embodiment of the present application, a counterweight 221 is further provided in the second accommodation chamber. Limiting structures are respectively provided on the second upper housing 21 and the second lower housing 22 for fixing the configuration block in the second accommodation chamber. Through the counterweight 221, when the upper cover 10 is opened, it can play a balancing role to prevent the charging base 100 from tilting.

[0088] Further, in order to facilitate the installation of the charging contact 271 and improve the service life of the charging contact 271, as Figure 6 shown, in the embodiment of the present application, the charging contact 271 includes a clamping portion 2711 and a plugging portion 2712; the clamping portion 2711 is hollow inside, one end of the clamping portion 2711 is provided with a first contact point 2714, and a second spring 2713 is arranged inside. The clamping portion 2711 is clamped with the second upper housing 21 for electrically connecting the first contact point 2714 with the circuit board 28 under the extrusion of the second spring 2713; the plugging portion 2712 is hollow inside, and a third spring 2715 is arranged inside. One end of the plugging portion 2712 is plugged with the end of the clamping portion 2711 far from the circuit board 28, so that the second spring 2713 is electrically connected with the third spring 2715. The other end of the plugging portion 2712 is provided with a second contact point 2716, and the third spring 2715 is electrically connected with the second contact point 2716 for electrically connecting the second contact point 2716 with the device to be charged.

[0089] As Figure 6 shown, the charging contact 271 adopts the method of double-headed spring pins, without any welding required, and the electrical connection with the circuit board 28 and the device to be charged can be realized by using the pressure of the spring. The clamping portion 2711 is internally provided with a second spring 2713, and one end of the clamping portion 2711 is provided with a first contact point 2714. One end of the second spring 2713 abuts against the first contact point 2714, and the other end abuts against the other end of the clamping portion 2711. The second spring 2713 is used to provide an elastic force to the first contact point 2714 to electrically connect the first contact point 2714 with the circuit board 28. A protrusion is arranged on the outer edge of the clamping portion 2711, and the clamping portion 2711 is clamped with the second upper housing 21 through the protrusion. The plugging portion 2712 is hollow inside, and a third spring 2715 is arranged inside. The third spring 2715 abuts against the second contact point 2716 for forming an elastic pressure on the second contact point 2716 to electrically connect the second contact point 2716 with the device to be charged, and the plugging portion 2712 is plugged with the clamping portion 2711. Among them, the first contact point 2714 and the second contact point 2716 can be made of materials such as copper-plated platinum, which can also prevent corrosion, sweat and electrolysis while meeting the current demand.

[0090] In the embodiment of the present application, the charging contact 271 is fixed to the second upper housing 21 by means of a double-headed spring pin. The circuit board 28 and the device to be charged are electrically connected by the elastic force of the spring, enabling separate assembly between the circuit board 28 and the charging contact 271. It is not necessary to first weld the charging contact 271 to the circuit board 28 by soldering, thus improving the assembly efficiency.

[0091] Further, in order to make the structure of the charging base 100 more compact, as Figure 2B shown, a charging socket 29 is provided on the first limiting portion 24, and the charging socket 29 is electrically connected to the circuit board 28. In this way, the integration degree of the charging base 100 is greatly improved.

[0092] Figure 7 The application effect diagram of the charging base 100 provided by the embodiment of the present application is shown. It can be seen that the device to be charged 200 can be conveniently placed on the base through the first limiting portion and the second limiting portion. Just by placing the device to be charged 200, the electrical connection between the charging interface and the device to be charged is achieved, without the user having to specifically check whether the charging interface corresponds to the metal contacts on the device to be charged, thus improving the usability of the charging base. At the same time, during charging, the device to be charged is covered on the base by the upper cover, and the magnetic attraction portions at the edges of the upper cover and the base attract the upper cover and the base together, firmly enclosing the device to be charged in the accommodation space formed by the upper cover and the base. In this way, the connection between the device to be charged and the base is more stable and will not easily fall off. At the same time, by arranging the magnetic attraction portions at the edges of the base and the upper cover, the electromagnetic interference caused by the magnetic attraction portions to the charging circuit board on the base and to the device to be charged is avoided, improving the stability of charging the device to be charged. Figure 7

[0093] Another embodiment of the present application also proposes a charging system, as Figure 8 shown, the charging system includes the charging base 100 provided in any of the above embodiments and a charging cable 300; one end of the charging cable 300 is electrically connected to the charging base 100, and the other end is electrically connected to an external power supply.

[0094] The charging cable 300 is a common charging cable, one end of which is electrically connected to the charging circuit board, and the other end is electrically connected to an adapter. The external power supply is connected through the adapter to supply power to the charging base 100.
