Because the elastic support member 30 has an elastic support effect on the towing hook cover plate 20, after the external pressing force is eliminated, the pressing end 21 of the towing hook cover plate 20 cannot collapse, that is, the situation that the pressing end 21 collapses due to repeated pressing of the towing hook cover plate 20 can be prevented, so that the reasonable matching surface difference between the pressing end 21 and the automobile bumper is ensured.

In one embodiment, as shown in fig. 1, the elastic support 30 includes an elastic card 31 and a connecting bracket 32, the elastic support 30 is mounted on the towing hook cover 20 through the connecting bracket 32, one end of the elastic card 31 is connected to the connecting bracket 32, and the other end extends toward a direction approaching the towing hook accommodating cavity 12.

The sheet-like elastic card 31 is generally easily deformed, so that the supporting effect on the hitch cover 20 is better, and the connecting bracket 32 is provided to facilitate the connection of the sheet-like elastic card 31 to the hitch cover 20.

Specifically, the elastic card 31 and the connecting bracket 32 may be formed by bending and molding. The elastic card 31 may be made of a material capable of elastic deformation, such as a cold-rolled steel sheet, a copper plate, or the like.

In an embodiment, as shown in fig. 1, the elastic card 31 includes a supporting portion 311 and a deformation portion 312 that are fixedly connected, the deformation portion 312 is connected to the connecting bracket 32 through the supporting portion 311, and the deformation portion 312 is disposed at an included angle with the supporting portion 311.

In an embodiment, as shown in fig. 2 and 3, the number of the elastic cards 31 is two, the two elastic cards 31 are respectively a first elastic card 33 and a second elastic card 34, the first elastic card 33, the second elastic card 34 and the connecting bracket 32 are connected to form a U-shaped elastic support 30, the first elastic card 33 includes a first supporting portion 331 and a first deforming portion 332, the second elastic card 34 includes a second supporting portion 341 and a second deforming portion 342 deforming portion 312, the first supporting portion 331 and the second supporting portion 341 are arranged at intervals, the first deforming portion 332 is bent towards a direction approaching the second deforming portion 342, the second deforming portion 342 is bent towards a direction approaching the first deforming portion 332, a bayonet 13 is arranged on a side of the automobile bumper 10 approaching the towing hook accommodating cavity 12, the first deforming portion 332 is inserted into the bayonet 13 and is tightly matched with an inner wall of the bayonet 13, and the second deforming portion 342 is inserted into the bayonet 13 and is tightly matched with the inner wall of the bayonet 13.

Since the first deformation portion 332 is bent toward the direction close to the second deformation portion 342, the second deformation portion 342 is bent toward the direction close to the first deformation portion 332, and one end of the U-shaped elastic support 30 is inserted into the bayonet 13 through the first deformation portion 332 and is tightly matched with the inner wall of the bayonet 13, and the other end is inserted into the bayonet 13 through the second deformation portion 342 and is tightly matched with the inner wall of the bayonet 13. That is, the first deformation portion 332 and the second deformation portion 342 of the U-shaped elastic support 30 are integrally clamped into the bayonet 13 in a contracted shape, so that in a normal state, the first deformation portion 332 and the second deformation portion 342 are propped against the inner wall of the bayonet 13, thereby supporting the pressing end 21 of the towing hook cover plate 20, and keeping a proper matching surface difference between the towing hook cover plate 20 and the automobile bumper 10.

The pressure applied by the operator to the pressing end 21 of the towing hook cover plate 20 overcomes the supporting force of the first deformation portion 332 to the towing hook cover plate 20 and the supporting force of the second deformation portion 342 to the towing hook cover plate 20, so that the first deformation portion 332 and the second deformation portion 342 are pushed to be further inserted into the bayonet 13, the supporting effect of the first deformation portion 332 and the second deformation portion 342 to the towing hook cover plate 20 is lost, and the towing hook cover plate 20 is rotated to be opened.
