[0030] The present utility model provides a vehicle-mounted wireless charging device. Figures 1 to 5 This is a specific embodiment of the vehicle-mounted wireless charging device provided by the present utility model.

[0031] Referring to Figures 1 to 4 , the vehicle-mounted wireless charging device includes a charging head 1 and a telescopic bracket 2 for driving the telescopic movement of the charging head 1. The telescopic bracket 2 includes a rod body 21, a screw block 22 provided at the end of the rod body 21, and a movable sleeve 23 sleeved on the screw block 22. The movable sleeve 23 is threadedly connected to the screw block 22, and the charging head 1 is provided at one end of the movable sleeve 23 away from the rod body 21;

[0032] A rack 24 is provided on one side of the rod body 21, and a positioning block 25 meshing with the rack 24 is provided in the movable sleeve 23. The positioning block 25 is connected to the movable sleeve 23 through a spring.

[0033] Specifically, a limiting frame is provided on the second end cover 233. The positioning block 25 is located within the limiting frame and is limited by the limiting frame, such that the positioning block can only move along the extension direction of the spring (the radial direction of the movable sleeve).

[0034] In this embodiment, due to the threaded fit between the movable sleeve 23 and the screw block 22, when the movable sleeve 23 is rotated, the movable sleeve 23 can move relative to the screw block 22, thereby driving the charging head 1 to move along the length direction of the rod body 21, so that the charging head 1 can be telescoped, which is convenient for users. When the movable sleeve 23 is rotated, the movable sleeve 23 moves to drive the limiting frame to move, so that the limiting frame applies an external force to the positioning block 25 and the spring in the moving direction. The spring contracts under the external force, temporarily releasing the engagement between the positioning block 25 and the rack 24. At this time, the positioning block 25 can move relative to the rack 24. After stopping rotating the movable sleeve 23, the positioning block 25 engages with the rack 24 again under the elastic force of the spring, keeping the movable sleeve 23 fixed and achieving self-locking.

[0035] The movable sleeve 23 includes a rotating cylinder 231, a first end cover 232 and a second end cover 233 provided at both ends of the rotating cylinder 231. A slide rail 234 is connected between the first end cover 232 and the second end cover 233, and the screw block 22 is slidably sleeved on the slide rail 234. In this embodiment, by providing the slide rail 234, the screw block 22 is sleeved on the slide rail 234 and can slide relative to the slide rail 234, which increases the connection stability between the screw block 22 and the movable sleeve 23 and makes the movement of the movable sleeve 23 more stable. Specifically, the first end cover 232 and the second end cover 233 are respectively sleeved at both ends of the rotating cylinder 231, and the rotating cylinder 231 is respectively rotatably connected to the first end cover 232 and the second end cover 233. The side walls of the first end cover 232 and the second end cover 233 are provided with a number of notches. By providing the notches, the contact area between the first end cover 232, the second end cover 233 and the rotating cylinder 231 can be reduced, thereby reducing the rotational friction of the rotating cylinder 231 and facilitating the rotation of the rotating cylinder 231.

[0036] A limiting rib 235 is provided on the side surface of the slide rail 234, and a limiting groove 221 for abutting against the limiting rib 235 is provided on the screw block 22. By providing the limiting protrusion and the limiting groove 221, the connection between the screw block 22 and the slide rail 234 is made closer, further increasing the connection stability between the screw block 22 and the rotating cylinder 231 and preventing the screw block 22 and the rotating cylinder 231 from vibrating or shaking during the relative displacement process.

[0037] Specifically, an internal thread is provided on the side wall of the rotating cylinder 231, and an external thread meshing with the internal thread is provided on the side wall of the screw block 22. The rotating cylinder 231 and the screw block 22 are connected by the internal thread and the external thread, so that when the rotating cylinder 231 rotates, the rotating cylinder 231 can move relative to the screw block 22 to realize the telescopic process of the telescopic bracket 2.

[0038] The first end cover 232 is provided with a number of connecting columns 236 extending to abut against the second end cover 233. The connecting columns 236 and the second end cover 233 are connected by screws, and the screw block 22 is provided with a relief hole 222 for the connecting columns 236 to pass through. The first end cover 232 and the second end cover 233 are connected by screws to fix the rotating cylinder 231 between the first end cover 232 and the second end cover 233. The rotating cylinder 231 is rotatably connected to both the first end cover 232 and the second end cover 233. The movement of the rotating cylinder 231 can be limited by the first end cover 232 and the second end cover 233 to prevent the rotating cylinder 231 from falling off the screw block 22. Specifically, a screw hole is provided on the connecting column 236, and a mounting hole is provided on the second end cover 233. The mounting hole and the screw hole are connected by screws.

[0039] A first knob 237 is sleeved on the rotating cylinder 231. A clamping block is provided on the side wall of the rotating cylinder 231, and a clamping groove engaged with the clamping block is provided on the side wall of the first knob 237. Specifically, an annular groove for the first end cover 232 and the second end cover 233 to extend into is provided on the inner wall of the first knob 237. The functions of the first knob 237 are: one is to drive the rotating cylinder 231 to rotate, and the other is to connect the rotating cylinder 231, the first end cover 232, and the second end cover 233 into an integral body.

[0040] The in-vehicle wireless charging device further includes a connection mechanism 3 connecting the telescopic bracket 2 and the charging head 1. The connection mechanism 3 includes a connection ball 31 provided on the telescopic bracket 2, a ball joint 32 sleeved on the connection ball 31, and a second knob 33 sleeved on the ball joint 32. The second knob 33 is used to lock the connection ball 31 and the ball joint 32. It can be understood that since the ball joint 32 is sleeved on the connection ball 31, when the second knob 33 is unlocked, the ball joint 32 can rotate relative to the connection ball 31, so that the angle of the charging head 1 can be adjusted to facilitate the user to adjust according to needs. If the ball joint 32 has a certain elasticity, the ball joint 32 can also be detached from the connection ball 31, so that the charging head 1 is detachable, which is convenient for the user to charge while using when picking up a terminal device such as a mobile phone for use. It should be noted that the connection mechanism 3 includes but is not limited to the mechanism composed of the connection ball 31, the ball joint 32, and the second knob 33. In other embodiments, the connection mechanism 3 can also be composed of a screw and a screw hole, or a buckle and a buckle hole, etc.

[0041] Further, the ball joint 32 includes a plurality of sheet units 321 surrounding a spherical shape. The plurality of sheet units 321 are spaced apart from each other, and the second knob 33 is threadedly connected to the sheet unit 321. It can be understood that since there is a gap between the sheet units 321, the sheet units 321 can rotate inward or outward, so that the ball joint 32 can be contracted and expanded (i.e., has elasticity), enabling the ball joint 32 to be detached from the connection ball 31. Specifically, the second knob 33 is sleeved on the ball joint 32, and mutually engaged threads are provided on the inner wall of the second knob 33 and the outer wall of the sheet unit 321.
