Vehicle frame and vehicle comprising same

Abstract

The invention relates to a vehicle frame and a vehicle comprising the same. The vehicle frame comprises a driving area and a passenger area. A crushing type energy absorption structure is arranged between the driving area and the passenger area and/or arranged in the position, close to the rear portion of the driving area, of the passenger area. When the front portion of the vehicle is collided, collision energy is backwards transmitted to the crushing type energy absorption structure through the driving area, the crushing type energy absorption structure is subjected to crushing deformation to absorb the collision energy, the structure of the driving area stays the same, and the driving area overall moves backwards along with energy absorption structure deformation, so that the safety of passengers over the driving area is ensured. According to the vehicle frame and the vehicle comprising the same, the rigidity and flexibility of the vehicle frame are reasonably distributed and designed, when the front portion of the vehicle is collided, a driving area vehicle frame body loaded with a driver cannot be deformed and can overall move backwards, the crushing type energy absorption structure is subjected to crushing deformation to absorb the collision energy, and the purpose of protecting the driver and the passengers is achieved.

Description

technical field [0001] The invention relates to the field of vehicle collision safety design, in particular to a vehicle frame and a vehicle with the vehicle frame. Background technique [0002] In the process of vehicle frontal collision, protecting the life safety of the driver and passengers is the goal of vehicle passive safety design. At present, the overall collision energy absorption is not considered in the design of the front structure of the vehicle. The frame of the driving area and the rear frame of the driving area are directly connected and the connecting profiles are the same, so the absorption of collision energy is very limited, and the vehicle in the driving area Both the frame and the frame in the passenger area are deformed, so that the corresponding occupant space above the driving area of ​​the frame cannot be guaranteed, and the driver is vulnerable to injury. In order to ensure the occupant's living space and reduce the occupant's injury, the frame s...
