Problems solved by technology

The vehicle frame generally includes longitudinal beams and cross beams. The front part of the longitudinal beams is provided with a deformation zone, which is used to absorb the energy of the collision impact. It is difficult for existing vehicles to ensure that the collision occurs from the front of the longitudinal beams. In addition, due to the short length of the deformation zone, the effective length of energy absorption cannot be guaranteed

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] As shown in Figure 1, a kind of vehicle frame structure, it comprises the longitudinal beam 1 that is arranged on both sides of vehicle, and the front part of described longitudinal beam 1 is provided with crushing deformation inducing part 11; This crushing deformation inducing part 11 is The crush deformation induction groove 111 may also be an induction hole or an induction rib, which is used for weakening treatment when compression collapse occurs in the axial direction of the longitudinal beam. Combined with the reasonable configuration of the material and material thickness of the longitudinal beam, when a collision occurs, the impact energy can be more effectively absorbed, and the possibility of occupant injury is reduced.

[0019] As shown in Figure 2, the upper left of Figure 2 is a schematic diagram of the existing collision d...

Abstract

The invention provides a vehicle frame structure which can guide area deformation to ensure the deformation area, effective energy absorbing and the security of passengers when impact occurs. The frame structure has the advantages that a front cross beam can be deformed to absorb energy when the impact occurs; simultaneously, a carling can be deformed to absorb energy according to the guide of a press-burst deformation guide part but fallback to prevent the carriage from being impacted. In addition, a groove-shaped reinforcing plate is embedded into a carling body with a groove-shaped part toenhance the energy absorbing efficiency of the carling. The middle of the carling is provided with a reinforcing structure to form a closed loop with a door frame, and the anti-impact capacity of thecarriage can be greatly enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a vehicle frame structure. 【Background technique】 [0002] The frame is the installation basis of each component on the vehicle, which bears most of the weight of the vehicle. When the vehicle is impacted, the frame will be subjected to impact loads. Therefore, the frame is required to have sufficient strength, appropriate rigidity, and at the same time reduce weight as much as possible . The vehicle frame generally includes longitudinal beams and cross beams. The front part of the longitudinal beams is provided with a deformation zone, which is used to absorb the energy of the collision impact. It is difficult for existing vehicles to ensure that the collision occurs from the front of the longitudinal beams. In addition, due to the short length of the deformation zone, the effective length of energy absorption cannot be guaranteed. 【Content of invention】 [0...
