Instrument panel cross beam connection structure and vehicle

Abstract

The invention provides an instrument panel cross beam connection structure and a vehicle, relating to a vehicle. The instrument panel cross beam connection structure comprises an instrument panel cross beam main body, a cowl metal plate and a front support, wherein the instrument panel cross beam main body is used for supporting instrument panel system components of the vehicle; the cowl metal plate is arranged in front of the instrument panel cross beam main body in the direction towards the headstock; the front support is used for preventing the instrument panel cross beam main body from concussion burst or rupture when the vehicle is impacted; and the front support can connect and support the instrument panel cross beam main body and the cowl metal plate, and can be crushed and deformed before the instrument panel cross beam main body when the vehicle is impacted. The front support can be crushed and deformed before the instrument panel cross beam main body, and can absorb the impact force generated by the impact in the crushing and deformation process. Therefore, the concussion burst or rupture probability of the instrument panel cross beam main body is greatly lowered, thereby effectively protecting the personal safety of passengers in the vehicle.

Description

technical field [0001] The invention relates to a vehicle, in particular to an instrument panel beam connection structure and the vehicle. Background technique [0002] For vehicles, the instrument panel beam assembly is the internal skeleton of the instrument panel system, which supports the instrument panel system, provides the installation position of the internal components of the instrument panel system, and also plays a certain role in increasing the strength of the entire body. It is the instrument panel system and the body in white. Assembly connection bracket. [0003] At present, the vast majority of vehicles on the market use iron pipe dashboard beams, which are heavy and have complicated welding processes, which are not conducive to vehicle fuel economy and carbon emission indicators; while very few vehicle manufacturers use light metal materials such as magnesium aluminum The alloy instrument panel cross beam connects the instrument panel cross beam from the fr...

Problems solved by technology

[0003] At present, the vast majority of vehicles on the market use iron pipe dashboard beams, which are heavy and have complicated welding processes, which are not conducive to vehicle fuel economy and carbon emission indicators; while very few vehicle manufacturers use light metal materials such as magnesium aluminum Alloy instrument panel beam, which connects the instrument panel beam from the front support structure to the front wall sheet metal to ensure that the overall strength, stiffness and vehicle mode (NVH) level are sufficient

[0004] However, when a vehicle collides, especially when the front of the vehicle is hit, the instrument panel beam, front support structure, cowl sheet metal and other corresponding parts (such as the brake pedal arm) will be affected by the strong impact force. It will press on the passengers in the hit vehicle, seriously threatening the personal safety of passengers
