Embodiment 2

[0071] Embodiment 2 of the vehicle side impact protection structure in the present invention: the difference from the above-mentioned embodiments is that in this embodiment, only one hatch reinforcement beam is provided on the hatch door and is arranged obliquely along the oblique line, still A cross-arranged structure can be formed with the transverse anti-collision beam.

Embodiment 3

[0072] Embodiment 3 of the vehicle side impact protection structure in the present invention: the difference from the above embodiments is that in this embodiment, the hatch reinforcement beam is a solid rod or rod. In other embodiments, the hatch reinforcement beam may adopt a hollow structure, which is no longer filled with integral fillers.

Embodiment 4

[0073]Embodiment 4 of the vehicle side impact protection structure in the present invention: the difference from the above embodiments is that in this embodiment, the hatch reinforcement beam adopts a section bar with a rectangular cross section. In other embodiments, hollow pipes or square steel can also be used. These profiles are all hollow structures, and their inner cavities are filled with fillers.

Abstract

The invention relates to a vehicle side collision protection structure which comprises a cabin door frame used for forming a cabin opening in the side face of a vehicle, and a transverse anti-collision beam is arranged in the cabin door frame; a cabin door which is arranged at the cabin door frame and used for sealing the cabin opening; and a cabin door reinforcing beam which is arranged on the cabin door, and the transverse anti-collision beam and the cabin door reinforcing beam are arranged in a crossed mode. The cabin door reinforcing beam is arranged on the cabin door, the cabin door reinforcing beam and the transverse anti-collision beam are arranged in a crossed mode, when side collision occurs, the cabin door reinforcing beam arranged on the cabin door can play a role in preventing the cabin door from being excessively deformed and preventing impact force from bypassing the transverse anti-collision beam to make direct contact with the energy supply device, the collision risk of the energy supply device can be reduced, and the protection capacity is improved; and compared with the prior art, the rigidity and strength are improved by purely increasing materials, the overall light weight of the protection structure can be achieved by increasing the cabin door reinforcing beam, and the production cost is reduced.

Description

technical field [0001] The invention relates to a vehicle side impact protection structure. Background technique [0002] In order to place energy supply devices such as battery boxes, fuel tanks or gas bottles that provide energy for the vehicle, an installation compartment is often provided on the side of the vehicle. In order to ensure the safety of these energy supply devices in the installation cabin, a protective structure for protecting the energy supply device is provided at the hatch of the installation cabin in the vehicle. The common protective structure in the prior art is to set a hatch at the hatch and Anti-collision beam. [0003] In order to protect the protection ability of the structure, the main measures taken by technicians at this stage are: ① Change the size of on-board energy sources such as battery boxes, fuel tanks or gas bottles, so that on-board energy can move laterally into the car as much as possible, extending the length of the on-board energy...
