[0049] In daily situations, the cover plate 1 is in the first position, and the cover plate 1 covers the towing hook opening to prevent other external objects from entering the towing hook opening and to ensure the appearance of the vehicle. Figure 1 、 Figures 3 to 5 、 Figure 9 The cover plate 1 shown in FIGS. 1 to 5 is in the first position. When it is necessary to install and use the towing hook, the driving member 4 is operated to drive the connecting rod structure 2 to move, and the connecting rod structure 2 drives the cover plate 1 to move, so that the cover plate 1 moves from the first position to the second position. Figure 2 The cover plate 1 shown in FIGS. 1 to 5 is in the first position. When it is necessary to install and use the towing hook, the driving member 4 is operated to drive the connecting rod structure 2 to move, and the connecting rod structure 2 drives the cover plate 1 to move, so that the cover plate 1 moves from the first position to the second position.

[0050] It should be noted that under the welcome function of the vehicle, the cover plate 1 can also be moved from the first position to the second position. After the welcome function of the vehicle ends, the cover plate 1 is moved from the second position to the first position.

[0051] As an example, the second position is located above the first position and is located at the inner side of the first position. In other embodiments, the second position can also be located below the first position and at the inner side of the first position, located at the left side of the first position and at the inner side of the first position, located at the right side of the first position and at the inner side of the first position, etc. It should be noted that in the description of the embodiments of the present application, the up-down and left-right positions are consistent with the up-down and left-right positions of the vehicle.

[0052] When the connecting rod structure 2 drives the cover plate 1 to move, the movement of the cover plate 1 is a reciprocating swing movement.
