[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1-3 As shown, a universal covering device for an automobile armrest cover comprises:

[0030] The frame 100 is provided with a first positioning assembly 110 and a second positioning assembly 120 with adjustable width. The first positioning assembly 110 is provided with a moving portion and a covering portion. The second positioning assembly 120 is arranged to be lifted above the covering portion, and a gap is provided between the second positioning assembly 120 and the covering portion. The initial position of the car armrest is located on the moving portion and can be moved to the covering portion or moved away from the first positioning assembly 110. The second positioning assembly 120 and the covering portion open the cover, and the car armrest can be moved through the second positioning assembly The first positioning assembly 110 and the second positioning assembly 120 are both adjustable in width to accommodate vehicle armrests and face covers of different diameters, and the second positioning assembly 120 can be raised and lowered to adjust the gap between the second positioning assembly 120 and the covering portion to facilitate entry of vehicle armrests of different heights, and the overall applicability of the device is good.

[0031] Preferably, the second positioning component 120 is provided with a first end close to the moving part and a second end away from the moving part, the height of the first end is higher than the height of the second end, and a guide portion 121 is provided at the first end, that is, when the car armrest enters the face cover, the height of its inlet is greater than the height of the outlet, so the car armrest can enter the face cover very conveniently, and when it goes out, since the outlet is small, the face cover will cover the car armrest and drive the face cover to separate from the second positioning component 120 and the covering portion, thereby realizing automatic assembly, and due to the existence of the guide portion 121, the car armrest is easier to enter the face cover.

[0032] Of course, in order to realize the movement of the rack 100 , universal wheels can be provided under the rack 100 .

[0033] The lifting mechanism 200 is disposed on the frame 100 and connected to the second positioning assembly 120 . The lifting mechanism 200 is used to drive the second positioning assembly 120 to perform lifting motion.

When the driving member drives the first gear 320 to move linearly, the linear movement of the first gear 320 will drive the movable rack 340 to rotate, and due to the meshing relationship between the fixed rack 330 and the first gear 320, the first gear 320 will rotate during the linear movement, and the first rack 330 will rotate. The rotation of the wheel 320 will also drive the movable rack 340 to rotate, and the rotation length of the movable rack 340 will be twice the linear motion stroke of the first gear 320, and the rotation length of the movable rack 340 will be converted into the stroke of the extrusion member in a 1:1 ratio. The stroke of the extrusion member is consistent with the stroke of the automobile armrest, so that the stroke of the automobile armrest can be twice the output stroke of the driving member, thereby increasing the stroke range of the automobile armrest and reducing the output motion range of the driving member; the forward and reverse rotation of the movable rack 340 determines the movement direction of the extrusion member. When the extrusion member moves toward the side of the covering portion, it can drive the automobile armrest into the covering portion and can drive the automobile armrest to separate from the first positioning assembly 110.
