The watch box 41 is fixedly disposed inside the main body 11, the sliding component 42 is slidably disposed on the watch box 41, and the watch charging module 43 is connected to the sliding component 42. The watch charging module 43 slides relative to the watch box 41 through the sliding component 42 and is used to extend out of the second storage opening 112 or retract into the second storage opening 112.

[0063] This embodiment features a watch charging module 43 for charging the watch. The watch charging module 43 can slide relative to the watch case 41 via the sliding component 42, and can extend out of or retract into the second storage opening 112. It is foreseeable that when the watch charging module 43 is in use, it can be slid out of the second storage opening 112 for convenient charging of the watch; when the watch charging module 43 is not in use, it can be slid back into the second storage opening 112 to save space occupied by the watch charging module 43.

[0064] Optional, see below Figure 6 and Figure 9 In one embodiment, an mounting plate 113 is inclinedly disposed in the middle of the inner cavity of the main body 11, and the watch box 41 is disposed on the mounting plate 113. In this embodiment, by setting the mounting plate 113 and placing the watch box 41 on the mounting plate 113, the space occupied by the mounting plate 113 in the inner cavity of the main body 11 can be reduced, thereby reducing the space occupied by the watch box 41 in the inner cavity of the main body 11.

[0065] Optional, see below Figure 7 and Figure 8 In one embodiment, a third storage opening 411 is provided through one side of the watch box 41. A first mounting groove 412 is provided at both ends of the watch box 41. The sliding component 42 includes two sliding rods 421 and a connecting seat 422.

A sleeve 423 is provided at both ends of the connecting seat 422. The sleeve 423 is slidably sleeved on the corresponding sliding rod 421. In this embodiment, the watch charging module 43 slides relative to the sliding rod 421 through the sleeve 423, and then slides relative to the watch box 41. It is used to extend out of the third storage opening 411 and the second storage opening 112 in sequence, or to retract into the second storage opening 112 and the third storage opening 411 in sequence.

[0066] Optional, see below Figure 7 and Figure 8 In one embodiment, a first limiting part 415 and a second limiting part 416 are respectively provided on the left and right sides of the watch box 41. The right end of the watch charging module 43 is slidably disposed in the first limiting part 415 and the second limiting part 416. When the right end of the watch charging module 43 slides to abut against the first limiting part 415, the left end of the watch charging module 43 extends out of the main body 11 through the third storage port 411 and the second storage port 112 in sequence. When the right end of the watch charging module 43 slides to abut against the second limiting part 416, the left end of the watch charging module 43 retracts into the watch box 41 through the second storage port 112 and the third storage port 411 in sequence.

[0067] In this embodiment, by setting the first limiting part 415 and the second limiting part 416, it is possible not only to ensure that the watch charging module 43 slides relative to the watch box 41 through the sliding component 42 without disengaging, but also to ensure that the watch charging module 43 can only extend and retract from the left side of the watch box 41. Compared with extending and retracting from both the left and right sides of the watch box 41, the watch charging module 43 in this embodiment requires a shorter length, which can save costs.

[0068] Optional, see below Figure 7 In one embodiment, the watch box 41 includes a watch top cover 413 and a watch bottom cover 414. A first limiting part 415 and a second limiting part 416 are respectively disposed on the left and right sides of the watch top cover 413.

[0070] The display screen 52 can be configured as a touch display screen 52 or a non-touch display screen 52.

[0071] Optional, see below Figure 10 In one embodiment, a third mounting groove (not shown in the figure) is provided between the front shell 12 and the main body 11 on the side opposite to the inner cavity of the main body 11. The wireless charging device also includes a lens 61 and a switch 62. The lens 61 is disposed in the third mounting groove and located outside the display screen 52. The switch 62 is disposed on the lens 61 and connected to the control motherboard 51. In this embodiment, by setting the switch 62, it can be directly controlled by the external switch 62 without using the touch display screen 52. Only the non-touch display screen 52 needs to be used, which not only saves costs, but also makes the external switch 62 very convenient to use.

[0072] It is worth noting that since the lens 61 is transparent, the image on the display screen 52 can be seen through the lens 61.

[0073] Optional, see below Figure 10 In one embodiment, switch 62 may be configured as a touch switch.

[0074] Optional, see below Figure 10 In one embodiment, a placement groove 115 is provided on the top of the main body 11.
