[0018] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1-5 Further analysis of this utility model is made.
[0019] like Figure 1-Figure 5As shown, a lifting mechanism for a car tailgate includes: a car box 1, a motor 2 is installed on the inner wall of the car box 1, screws 3 are fixedly installed on one side of two motors 2, threaded blocks 4 are threadedly connected to the surface of the screws 3, a movable rod 5 is fixedly installed on one side of the threaded block 4, a toothed belt 6 is fixedly installed on one side of the movable rod 5, a gear plate 7 is meshed and connected to the surface of the toothed belt 6, and the gear plate 7 is symmetrically fixedly installed on one side of the tailgate body 8.
[0020] When the tailgate body 8 needs to be lifted or unfolded on one side of the car box 1, the motor 2 is operated to drive the screw 3 to rotate, so that the threaded block 4 moves up and down on the surface of the screw 3, thereby driving the movable rod 5 to slide up and down in the limit groove 9. When the movable rod 5 moves, it also drives the toothed belt 6 to move, and the toothed belt 6 is engaged to drive the gear plate 7 to rotate. The gear plates 7 on both sides rotate, and then drive the tailgate body 8 to rotate to unfold and lift.
[0021] In the technical solution of the embodiment of the present application, a limiting groove 9 is provided inside the automobile box 1 , and a sliding groove 10 is provided on the inner walls of the two limiting grooves 9 , and the threaded block 4 is movably sleeved inside the sliding groove 10 .
[0022] When the threaded block 4 moves threadably on the surface of the screw rod 3, it also drives the movable rod 5 to slide in the limiting groove 9. At the same time, the threaded block 4 also slides in the sliding groove 10. The sliding groove 10 plays a certain limiting role and also limits the sliding distance of the threaded block 4.
[0023] In the technical solution of the embodiment of the present application, a card slot 11 is symmetrically opened on one side of the automobile box 1, and a hydraulic telescopic rod 12 is hingedly installed on the inner wall of the two card slots 11, and the bottom end of the hydraulic telescopic rod 12 is hingedly installed on one side of the tailgate body 8.
[0024] When the tailgate body 8 is rotated and raised on one side of the automobile box 1, the hydraulic telescopic rod 12 is in operation. The elasticity of the hydraulic telescopic rod 12 provides stability for the lifting of the tailgate body 8. When the tailgate body 8 is retracted and closed, the hydraulic telescopic rod 12 is also driven to retract. Since both sides are in a hinged state, the hydraulic telescopic rod 12 can be stored in the card slot 11 when it is fully retracted. Therefore, the card slot 11 plays a good storage role and avoids affecting the lifting and closing of the tailgate body 8.
[0025] In the technical solution of the embodiment of the present application, the tailgate body 8 is movably sleeved on one side of the automobile box 1 , and one side of the tailgate body 8 is arranged in an inclined surface.
[0026] When the tailgate body 8 is rotated and unfolded on one side of the automobile box 1 , since one side of the tailgate body 8 is arranged in an inclined surface, it can fit better, thereby improving the practicality of the tailgate body 8 .
[0027] In the technical solution of the embodiment of the present application, support plates 13 are fixedly installed at the bottom ends of the automobile box 1 and the tailgate body 8 , and hinges 14 are installed on one side of the two support plates 13 .
[0028] When the tailgate body 8 is rotated and unfolded on one side of the automobile box 1, the hinge 14 supports the connection between the tailgate body 8 and the automobile box 1 through the two support plates 13, thereby ensuring the balance and stability of the tailgate body 8, avoiding tilting due to gravity, and improving the bearing capacity of the tailgate body 8.
[0029] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
