Disclosure of Invention

The utility model aims to provide a: aiming at the problem that a spare tire box in the prior art is difficult to absorb collision energy, the encircling frame type vehicle tail structure capable of absorbing the collision energy is provided.

In order to realize the purpose of the utility model, the utility model provides a following technical scheme:

the utility model provides a surround frame type rear structure, is including being recessed spare tyre bottom of the case board, and spare tyre bottom of the case board circumference welding has annular additional strengthening, and additional strengthening is the cavity form.

By adopting the technical scheme, the utility model has the advantages that the annular reinforcing structure is welded around the bottom plate of the spare tire box, so as to reinforce the structure of the tail part of the vehicle; in addition, the reinforcing structure is hollow, so that when the automobile is impacted by rear-end collision and the like, the reinforcing structure can deform to absorb collision energy, the deformation of the spare tire box is reduced, and the rear-row passengers are protected.

Furthermore, the reinforcing structure is composed of two sections, namely a first reinforcing section which is in a straight shape and is positioned at the tail of the vehicle and a second reinforcing section which is in a concave shape. The reinforcing structure is divided into two sections and can be better matched with the appearance structure of the automobile; the first reinforcing section positioned at the tail of the vehicle is independently segmented, so that the first reinforcing section can be conveniently and independently replaced after the vehicle is collided at the rear.

Further, the hollow portion of the second reinforcing segment communicates with the hollow portion of the D-pillar. The structural strength of the second reinforcing section and the D column is enhanced, and the collision resistance of the automobile body is enhanced.

Furthermore, the first reinforcing section is formed by welding a vehicle tail rear skirt inner plate positioned above and a vehicle tail rear skirt outer plate positioned below; the inner plate of the rear skirt of the vehicle tail and the outer plate of the rear skirt of the vehicle tail are both L-shaped. The inner plate of the rear skirt of the vehicle tail and the outer plate of the rear skirt of the vehicle tail are both L-shaped, so that the processing of the inner plate and the outer plate of the rear skirt of the vehicle tail is convenient, and the welding mode is simplified.

Furthermore, a reinforcing cross beam is welded at the bottom of the bottom plate of the spare tire box. The reinforcing cross beam can reinforce the rigidity of the spare tire box and also plays a role in reinforcing the torsional strength of the vehicle tail.

Further, the reinforcing beam is hollow. The hollow structure has light weight, and meets the lightweight design concept; when the spare tire box deforms, energy can be absorbed, and deformation of the spare tire box is reduced.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: an annular reinforcing structure is welded around the bottom plate of the spare tire box, so that the structure of the tail part of the vehicle is reinforced; in addition, the reinforcing structure is hollow, so that when the automobile is impacted by rear-end collision and the like, the reinforcing structure can deform to absorb collision energy, the deformation of the spare tire box is reduced, and the rear-row passengers are protected.
