The top of the base 1 is provided with an arc groove 11; the charging stand 2 includes a charging coil 22 and a shell 21, the outer surface of the shell 21 includes a bearing surface 2111 and an arc-shaped rotating surface 213, the charging coil 22 is installed on one side of the shell 21 near the bearing surface 2111, the arc-shaped rotating surface 213 is partially accommodated in the arc groove 11 and abuts against the wall of the arc groove 11, the shell 21 is rotatably connected with the base 1 through a rotating shaft 121 to adjust the pitch angle of the bearing surface 2111, and the axis of the rotating shaft 121 passes through the sphere center corresponding to the arc-shaped rotating surface 213 and the wall of the arc groove 11.

[0031] Specifically, the charging stand 2 includes a charging coil 22 and a housing 21. The outer surface of the housing 21 includes a bearing surface 2111 and an arc-shaped rotating surface 213. The bearing surface 2111 is used to bear and fix the watch. The charging coil 22 is installed on one side of the housing 21 near the bearing surface 2111, so that the charging coil 22 can charge the watch. Figure 2 ( Figure 2 The dotted part against the bearing surface 2111 is a watch), the housing 21 is rotatably connected to the base 1 via the rotating shaft 121. When the charging stand 2 rotates, the arc-shaped rotating surface 213 can rotate along the arc-shaped groove 11, so that the pitch angle of the bearing surface 2111 relative to the base 1 can be adjusted, thereby adjusting the distance between the bearing surface 2111 and the top of the base 1, so that the charging stand 2 can charge watches of different sizes.

[0032] In addition, the arc-shaped rotating surface 213 is partially accommodated in the arc-shaped groove 11 and abuts against the groove wall of the arc-shaped groove 11, and the axis of the rotating shaft 121 passes through the sphere center corresponding to the arc-shaped rotating surface 213 and the groove wall of the arc-shaped groove 11. It can be understood that the axis of the rotating shaft 121 passes through the sphere center corresponding to the arc-shaped rotating surface 213 and the groove wall of the arc-shaped groove 11. When the arc-shaped rotating surface 213 rotates, the arc-shaped rotating surface 213 must always be partially accommodated in the arc-shaped groove 11 and abut against the groove wall of the arc-shaped groove 11, so that the arc-shaped groove 11 can provide support force for the arc-shaped rotating surface 213, thereby reducing the force on the rotating shaft 121, reducing the probability of damage to the rotating shaft 121, and helping to extend the service life of the rotating shaft 121.

[0033] In order to make the technical personnel in this field better understand the present utility model scheme, the following will be combined with the attached Figures 1 to 7 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0034] Further, as a specific implementation in some embodiments of the present utility model, Figure 3 Figure 4 , Figure 6 and Figure 7As shown, the base 1 is provided with a connecting seat 12, and the arc-shaped rotating surface 213 is provided with an avoidance hole 2121, which extends along the rotation direction of the shell 21. The connecting seat 12 is penetrated through the avoidance hole 2121, and one end of the connecting seat 12 is connected to the bottom of the arc-shaped groove 11, and the other end is rotatably connected to the inside of the shell 21 through the rotating shaft 121.

[0035] Specifically, the arc-shaped rotating surface 213 is provided with an avoidance hole 2121, and the avoidance hole 2121 extends along the rotation direction of the housing 21, so that the arc-shaped rotating surface 213 can avoid the connecting seat 12, ensuring that the arc-shaped rotating surface 213 can rotate along the arc-shaped groove 11. In addition, the connecting seat 12 is penetrated by the avoidance hole 2121, one end of the connecting seat 12 is connected to the bottom of the arc-shaped groove 11, and the other end is rotatably connected to the inside of the housing 21 through the rotating shaft 121. Therefore, the connecting seat 12 and the rotating shaft 121 are located inside the housing 21, making the appearance structure of the entire watch wireless charger 100 more concise and beautiful.

[0036] Further, as a specific implementation in some embodiments of the present utility model, Figure 3 Figure 4 and Figure 7 As shown, the rotating shaft 121 includes two shaft sections (not shown), and the two shaft sections are respectively arranged on two opposite sides of the other end of the connecting seat 12, and the two shaft sections are rotatably connected to the housing 21.

[0037] Specifically, the rotating shaft 121 includes two shaft sections, which are respectively arranged on two opposite sides of the other end of the connecting seat 12, and the two shaft sections are rotatably connected to the housing 21. Therefore, both sides of the other end of the connecting seat 12 are rotatably connected to the housing 21 to ensure the stability of the connection.

[0038] Further, as a specific implementation in some embodiments of the present utility model, Figure 3 , Figure 4 and Figure 7 As shown, the rotating shaft 121 is integrally formed with the connecting seat 12. Specifically, the rotating shaft 121 is integrally formed with the connecting seat 12, so that the assembly mode of the rotating shaft 121 and the connecting seat 12 is more compact and stable, while reducing the number of parts and assembly steps, simplifying the manufacturing process.

[0039] As a specific implementation in some embodiments of the present utility model, Figure 3 and Figure 4 As shown, the charging base 2 also includes a damping sleeve 23, which is installed on the rotating shaft 121. A rotating seat 2122 is provided inside the shell 21, and an axial hole (not shown) for inserting the rotating shaft 121 is provided on the rotating seat 2122. The outer wall of the damping sleeve 23 abuts against the hole wall of the axial hole.

[0040] Specifically, the rotating seat 2122 is provided with an axial hole for inserting the rotating shaft 121, and the damping sleeve 23 is installed on the rotating shaft 121, and the outer wall of the damping sleeve 23 abuts against the hole wall of the axial hole. Therefore, the damping sleeve 23 can provide a damping force between the rotating shaft 121 and the rotating seat 2122, thereby preventing the charging seat 2 from rotating when charging the watch, and increasing the stability of the charging seat 2.

[0041] Further, as a specific implementation in some embodiments of the present utility model, Figures 4 to 6 As shown, the rotating seat 2122 includes a first seat body 2122a and a second seat body 2122b. The first seat body 2122a is integrally formed with the shell 21, and the second seat body 2122b is installed on the first seat body 2122a. A first semicircular groove 2122a1 is provided on the side of the first seat body 2122a facing the second seat body 2122b, and a second semicircular groove 2122b1 is provided on the side of the second seat body 2122b facing the first seat body 2122a. The first semicircular groove 2122a1 and the second semicircular groove 2122b1 jointly define an axial hole.

[0042] Specifically, the second seat body 2122b is mounted on the first seat body 2122a, and a first semicircular groove 2122a1 is provided on a side of the first seat body 2122a facing the second seat body 2122b, and a second semicircular groove 2122b1 is provided on a side of the second seat body 2122b facing the first seat body 2122a, and the first semicircular groove 2122a1 and the second semicircular groove 2122b1 jointly define an axial hole. Thus, the first semicircular groove 2122a1 and the second semicircular groove 2122b1 can clamp the rotating shaft 121 and the damping sleeve 23, and limit the damping sleeve 23 in the axial hole, thereby increasing the stability of the connection between the rotating shaft 121 and the damping sleeve 23 and the rotating seat 2122. In addition, the shell 21 of the charging stand 2 can be divided into a first shell 21121 and a second shell 21221, so that the second seat body 2122b can be installed on the first seat body 2122a, and the rotating shaft 121 and the damping sleeve 23 can be installed in the shaft hole.

[0043] It is worth mentioning that Figure 5 As shown, a stopper 2122b2 is provided on one side of the second seat body 2122b facing the second seat body 2122b, and the stopper 2122b2 is provided on both sides of the shaft hole. Thus, the stopper 2122b2 can limit the damping sleeve 23 in the shaft hole to prevent the damping sleeve 23 from escaping from the shaft hole, so as to prevent the connection structure between the rotating shaft 121 and the rotating seat 2122 from loosening.

[0044] Further, as a specific implementation in some embodiments of the present utility model, Figure 4 and Figure 7 As shown, the charging stand 2 further includes a positioning magnetic block 24 , which is disposed at the center of the charging coil 22 .

[0045] Specifically, the positioning magnetic block 24 can generate magnetic attraction on the back shell of the watch to fix the watch on the bearing surface 2111. The positioning magnetic block 24 is set at the center of the charging coil 22. It can be understood that when the positioning magnetic block 24 fixes the watch on the bearing surface 2111, the charging area of ​​the watch can be accurately aligned with the charging coil 22. Through this positioning method, energy transmission will be more efficient, which can effectively reduce energy loss, improve charging speed and ensure the smooth progress of the charging process.

[0046] It is worth mentioning that Figure 4 and Figure 7 As shown, a mounting frame 2122b3 is provided on the side of the second seat 2122b facing the bearing surface 2111, and the positioning magnet 24 and the charging coil 22 are mounted on the mounting frame 2122b3, and the positioning magnet 24 and the charging coil 22 are in contact with the inner wall of the bearing surface 2111. Therefore, on the one hand, the bearing surface 2111 and the mounting frame 2122b3 can provide a holding force to the positioning magnet 24 and the charging coil 22, so that the positioning magnet 24 and the charging coil 22 can be more stably mounted on the second seat 2122b. On the other hand, the positioning magnet 24 and the charging coil 22 are in close contact with the bearing surface 2111, which can improve the efficiency of magnetic induction between the charging coil 22 and the watch, ensure that the watch can fully receive the charging energy, and improve the charging speed and efficiency.
