Embodiment

[0020] Embodiment: a kind of inflatable automobile body stringer, as figure 1 , figure 2 , image 3 shown. The vehicle body longitudinal beam comprises a longitudinal beam front part 1 connected with the front bumper and a longitudinal beam rear part 2 connected with the front fender of the vehicle. The longitudinal beam of the vehicle body is a hollow structure, the wall thickness of the front part 1 of the longitudinal beam is small, and a guide groove 3 is provided on the side wall to guide the collapse direction of the front longitudinal beam during a collision, and the wall thickness of the rear part 2 of the longitudinal beam is thick, and is strengthened Structures such as boards increase rigidity and protect occupants.

[0021] Such as figure 2 , image 3 As shown, the interior of the front part 1 of the stringer is provided with an air bag 4, which is pre-filled with gas of 3 times the atmospheric pressure. Attached to the front end of the front part 1 of the ...

Abstract

The invention relates to an automobile body structure, in particular to an automobile body longitudinal beam structure provided with a built-in air bag, and solves the problem that the fixed rigidity of the conventional automobile body longitudinal beam cannot adapt to multiform collision energy absorption. The automobile body longitudinal beam structure comprises an energy-absorbing longitudinalbeam front part connected with a front bumper, and a high-rigidity longitudinal beam rear part connected with a front baffle plate. The interior of the longitudinal beam is hollow. The automobile body longitudinal beam structure is characterized in that: an air bag is arranged in the longitudinal beam front part; the air bag is aerated to ensure that the periphery of the air bag is clung to the inner wall of the longitudinal front part; a pressure sensor is arranged in the air bag; and a controllable valve opened and closed by a pressure sensor is arranged on one side of the air bag. The automobile body longitudinal beam structure can adjust the overall rigidity of the longitudinal beam front part according to different collision conditions, thereby realizing deformation energy absorptionunder different collision conditions.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to an automobile body longitudinal beam structure with a built-in air bag. technical background [0002] The longitudinal beam of the automobile body is the key force-transmitting component of the frontal structure of the automobile body. In the frontal collision accident of the automobile, the front section of the automobile longitudinal beam collapses and deforms to absorb energy, thereby reducing the amplitude of the deceleration of the vehicle body; the rear section of the longitudinal beam requires better stiffness. Avoid deformation of the passenger compartment to cause damage to the occupants. The front section of the body longitudinal beam commonly used now adopts a guide groove structure to guide the longitudinal beam to collapse and deform; the rear section adopts a rib or a stiffener structure to strengthen it to ensure its rigidity. The rigidity value of the longitudinal ...
