Frame capable of improving safety performance

Abstract

The invention discloses a frame capable of improving safety performance. The frame capable comprises a vehicle cabin, an anti-collision beam front beam and a bottom longitudinal beam; the anti-collision beam is arranged at the front end of the vehicle cabin and is rotatably connected to the vehicle bin thorugh a front beam; a main frame is arranged at the bottom of the vehicle cabin, a stop leveris perpendicularly arranged on the side wall of the rear end of the main frame, the bottom longitudinal beam is arranged under the main frame, one end of the bottom longitudinal beam is fixedly connected with the anti-collision beam, the other end of the bottom longitudinal beam is rotationally connected with the vehicle cabin through a rear beam, and the rear beam is of an arc-shaped structure and makes contact with the stop lever. The bottom longitudinal beams are provided with main frame sliding grooves in sliding fit with the bottom longitudinal beams. The main frame is detachably connected with the main frame sliding grooves, the tail end of the main frame is downwards provided with a stop block, and a spring is arranged between the stop block and the bottom longitudinal beam, so thatimpact force generated after head-on collision can be effectively buffered, discomfort of people in a vehicle is reduced, and injuries to people are reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle frame capable of improving safety performance. Background technique [0002] The frame, also known as the girder, is the base of the car and has sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. [0003] The method of traditional frame to protect personnel in traffic accidents is mainly to increase the strength of the frame. This method not only increases the weight of the car body, but also has little effect in the actual impact. Due to the rigid structure of the frame, it will Finally, the impact force cannot be effectively buffered, and the occupants of the car will feel discomfort caused by the strong impact force, which will also cause a certain degree of damage to the personnel. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a vehicle frame that can improve s...
