Embodiment Construction

[0039] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] Embodiment one of the automobile of the present invention, as Figure 1 to Figure 10 shown. The automobile in the present invention is a passenger car, and the passenger car includes a vehicle frame, and the vehicle frame includes a frame body and an energy-absorbing device 1 arranged at the front end of the frame body.

[0041] The energy absorbing device 1 includes an anti-collision beam 4 extending in the left-right direction and two energy absorbers 5 spaced along the left-right direction. The front end of the energy absorber 5 is fixed to the rear end of the anti-collision beam 4 by welding. The anti-collision beam 4 is a steel or aluminum thin-wall cavity structure with ribs. The energy absorber 5 includes an outer cylinder 6 whose length extends along the front-to-back direction and reinforcing ribs 7 arranged in the outer cylinder. There...

Abstract

The invention relates to an automobile and a car frame thereof. The automobile comprises a car frame, wherein the car frame comprises a frame body; the frame body comprises at least one longitudinal force transferring unit; the longitudinal force transferring unit comprises at least one cab longitudinal force transferring beam and at least one front axle longitudinal force transferring beam; a middle force transferring beam is connected between the back end part of at least one cab longitudinal force transferring beam and the corresponding front axle longitudinal force transferring beam. When a high-velocity impact happens to the automobile, impact force is transferred from the front end of the cab longitudinal force transferring beam to the back end part of the cab longitudinal force transferring beam, then is backwards transferred to the front axle longitudinal force transferring beam, and is subsequently transferred to other places of a front axle frame body part through the front axle longitudinal force transferring beam; the front axle frame body part generates deformation; impact energy is absorbed; the acceleration of the automobile is decreased; an inertia-force injury from which a driver suffers is reduced; meanwhile, the deformation of a cab frame body part corresponding to a cab is decreased and a living space for the driver is guaranteed.

Description

technical field [0001] The invention relates to an automobile and its frame. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements for the safety performance of automobiles. The front collision of automobiles is the most common accident type in automobile accidents. side driver. In order to protect the safety of the driver and passengers when the car collides in front, an energy absorbing device is usually arranged at the front of the car. [0003] For example, the authorized announcement number is CN 204527323 U, and the Chinese patent titled a frame discloses a frame. The vehicle includes a frame. Beam (equivalent to the longitudinal force transmission beam of the front axle), the rear energy-absorbing structure fixedly installed behind the front longitudinal beam is arranged between the front longitudinal beam and the middle longitudinal beam, and the rear energy-absorbing structure can absorb the...
