Through setting up front plate 71 and preceding shrouding 72, strengthened the intensity of threshold front end structure for when little offset collision, this department receives point and wheel contact, ensures that collision energy mainly transmits to the back end of threshold through the threshold, only partial energy transfer gives the A post, effectively avoids A post fracture deformation.

Of course, other structures of the vehicle and its working principle are understood and can be implemented by those skilled in the art, and detailed description thereof is omitted herein.

In summary, according to the vehicle provided by the embodiment of the utility model, the structural strength of the A column and the threshold is optimized, and when in small offset or other types of collision, part of energy generated in the collision process can be transmitted to the rear section of the threshold through the threshold, and only part of energy is transmitted to the A column, so that the fracture deformation of the A column is effectively avoided, the injury of passengers in a cockpit is avoided, and the driving safety is improved.

While certain specific embodiments of the utility model have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the utility model. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
