[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 As shown, a high-power vehicle-mounted USB fast charging device includes a high-power fast charging housing 1, a movable charging interface 2 that can slide relatively symmetrically inside the high-power fast charging housing 1, a driving component 3 for the movement of the movable charging interface 2 inside the high-power fast charging housing 1, a dust-proof cover 4 slidably installed symmetrically on the top of the high-power fast charging housing 1, and a USB hook-shaped plate 5 rotatably installed on the outer wall of one side of the movable charging interface 2.

[0024] As Figure 2 shown, a wire passing hole 6 is opened on the inner bottom wall of the high-power fast charging housing 1, and spare charging interfaces 7 are fixedly installed at both ends of the high-power fast charging housing 1 to provide more charging interfaces for the staff and facilitate the staff.

[0025] As Figure 4As shown in the figure, a T-shaped sliding groove is provided on the inner wall of one side of the high-power fast charging housing 1. T-shaped sliding blocks 8 are fixedly installed on the outer walls of one sides of the movable charging interfaces 2 symmetrically arranged inside the high-power fast charging housing 1. The T-shaped sliding blocks 8 are slidably clamped with the T-shaped sliding groove. Threaded sleeves 9 are fixedly installed on the outer walls of the other sides of the movable charging interfaces 2 symmetrically arranged inside the high-power fast charging housing 1. A lead screw groove is provided on the inner wall of one side of the high-power fast charging housing 1. The driving assembly 3 is arranged in the lead screw groove. The driving assembly 3 includes a biaxial motor 301. Driving lead screws 302 are fixedly installed at both output ends of the biaxial motor 301. The driving lead screws 302 are rotationally engaged with the threaded sleeves 9. So that when a staff member docks a USB connector with the movable charging interface 2, and at this time when the movable charging interfaces 2 are close together and the space is small, the staff member turns on the power supply of the biaxial motor 301 at this time. At this time, the biaxial motor 301 drives the driving lead screw 302 to rotate. At this time, the driving lead screw 302 drives the threaded sleeve 9 to move. At this time, the movable charging interfaces 2 move towards each other, thereby achieving the purpose of adjusting the movable charging interfaces 2 and facilitating the operation of the staff member.

[0026] As Figure 3 shown, limiting sliding grooves are provided on the outer walls of both sides of the high-power fast charging housing 1. Limiting sliding blocks 10 are fixedly installed on both side walls of the dust-proof cover 4. The limiting sliding blocks 10 are slidably clamped with the limiting sliding grooves. Spring grooves are provided at the four corners of the high-power fast charging housing 1. Clamping springs 11 are fixedly installed in the spring grooves. Clamping tapered rods 12 are fixedly installed at one ends of the clamping springs 11. Clamping grooves are provided at the four corners of the dust-proof cover 4. The clamping tapered rods 12 are slidably clamped with the clamping grooves. So that the staff member can achieve the sliding and limiting effects of the dust-proof cover 4 through the sliding clamping between the clamping springs 11 and the clamping grooves.

[0027] As Figure 5 and Figure 6As shown, on one side outer wall of the movable charging interface 2, support plates 13 are symmetrically and fixedly installed. The USB hook-shaped plate 5 is rotatably installed between the support plates 13. On one end of the USB hook-shaped plate 5, positioning grooves 14 are evenly formed along the circumference. On one side surface of the support plate 13 on one side of the movable charging interface 2, a positioning block 15 is fixedly installed. On one end surface of the positioning block 15, a fixing groove is formed. In the fixing groove, a positioning spring 16 is fixedly installed. One end of the positioning spring 16 is fixedly installed with a positioning tapered rod 17. One end of the positioning tapered rod 17 penetrates through the support plate 13 and extends into the positioning groove 14 inside the USB hook-shaped plate 5. So that after the staff docks the USB connector with the movable charging interface 2, at this time, the staff can rotate the USB hook-shaped plate 5 to engage the USB connector, and then can fix and limit the USB connector. At the same time, through the cooperation between the positioning spring 16, the positioning tapered rod 17 and the positioning groove 14, the limit fixation of the USB hook-shaped plate 5 can be realized, thereby ensuring the stable support of the USB hook-shaped plate 5.
