Embodiment Construction

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0020] The invention discloses a vehicle frame, which comprises a longitudinal beam 1, a front beam 2 and a rear support beam 3. The longitudinal beam 1 has two parallel beams. The front beam 2 is fixedly arranged at the front ends of the two longitudinal beams 1; the rear support A beam 3 is supported between two of said longitudinal beams 1 .

[0021] On the inner side wall of one longitudinal beam 1, a first indentation 11 is formed, and on the outer side wall of the other longitudinal beam 1, a concave first indentation 11 is also fo...

Abstract

The invention discloses a vehicle frame comprising: two longitudinal beams arranged in parallel; a front beam fixedly arranged at the front ends of the two longitudinal beams; a rear support beam supported between the two longitudinal beams; wherein a first indentation is formed on the inner side wall of one of the longitudinal members and a first indentation is formed on the outer side wall of the other longitudinal member. The first indentation has a concave structure with the longitudinal beam extending direction as a first direction, and the first indentation extending direction is perpendicular to the first direction. When the vehicle frame of the invention is impacted, if the impacting force is not balanced in the energy absorption area, the longitudinal beam will be bent along the first indentation, and the first indentation of the two longitudinal beams, one on the inner side and one on the outer side, can ensure the same bending direction, absorb the energy of the turning machine through the deformation, and ensure the safety of the personnel inside the vehicle.

Description

technical field [0001] The present invention relates to vehicle structures, and more particularly to vehicle frames. Background technique [0002] With the development of society, people pay more and more attention to the safety of automobiles, requiring them to withstand strict frontal and side collisions, so that the safety of drivers and passengers can be guaranteed. In the evaluation of the New Car Assessment Program (NCAP), the stiffness of the passenger compartment is directly related to the injury of the occupants. If the stiffness of the passenger compartment is high, the deformation of the cabin body in the collision is small, and the living space of the occupants is guaranteed. The damage will be reduced accordingly. However, the rigidity cannot be made too strong, because certain energy absorption requirements need to be met during a collision, and only sheet metal deformation can produce energy absorption. [0003] In the process of using a car, the most likely...
