Vehicle cycle frame structure with deformation guiding arrangement

Abstract

The invention belongs to the vehicle manufacturing technical field, and relates to a frame structure of a vehicle, in particular to a vehicle frame structure with a deformation guide device. The vehicle frame structure of the deformation guide device comprises a front cross beam and a front carling, wherein, the front carling comprises a big beam and a reinforcing plate, and the big beam is provided with a press-burst deformation guide part. Compared with the prior art, the vehicle frame structure provided with the deformation guide device ensures that the deformation can be started from the further end of the carling in impact and the effective power absorbing length can be ensured, and the power absorbing effect can be greatly exerted through the press-burst deformation guide part arranged on the front end of the big beam. The front cross beam can be deformed in impact to absorb energy, simultaneously, the carling can be deformed to absorb energy according to the designed requirement but fallback, so impact and extrusion for carriage can be prevented, simultaneously, the residual impact energy passes through the total reinforcing structure to prevent the deformation of the carriage and the opening of the vehicle door.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and relates to a vehicle frame structure, in particular to a vehicle frame structure with a deformation guiding device. Background technique [0002] The longitudinal collision of a car is the most likely form of collision, and it is also the most harmful form of collision to the life and property safety of the drivers and passengers in the vehicle. The length of the deformation zone at the front of the minibus is usually short. At present, the deformation zone absorbs more energy basically by increasing the stiffness of the deformation zone. However, the high stiffness of the deformation zone leads to an increase in the deceleration value during the collision process, and the deceleration of the structure has a direct relationship with the collision safety regulations and crashworthiness technical indicators. The high rigidity of the front deformation zone will inevitably affect t...

However, the high stiffness of the deformation zone leads to an increase in the deceleration value during the collision process, and the deceleration of the structure has a direct relationship with the collision safety regulations and crashworthiness technical indicators

The high rigidity of the front deformation area will inevitably affect the rear passenger area, and the huge momentum generated during the collision is directly transmitted to the passenger compartment, causing great damage to the occupants.

Moreover, due to the irregular deformation of the front longitudinal beam during the collision, the remaining impact force cannot be uniformly transmitted throughout the entire structure of the vehicle body, causing deformation of the passenger compartment and affecting the opening of the door. Passengers suffered more serious injuries
