Embodiment Construction

[0027] In existing dashboard beams, the structure that supports the steering column of the car is attached to the body assembly, specifically, to the cowl area of ​​the body, such as the lower beam under the front end of the windshield. When the vehicle has a frontal collision, the above-mentioned structure will directly transmit the longitudinal force generated by the collision from the engine compartment to the dashboard crossbeam through the front windshield lower crossbeam, thereby causing the risk of displacement of the steering column.

[0028] Due to the need to support the steering column load, the effective mass of the dashboard beam is concentrated in the driver's side area. In this way, when the steering wheel connected to the steering column pops up backwards, on the one hand, it may directly hit the driver and passengers, causing greater damage; It will cause an impact, and then affect the position where the human body hits the airbag, and it is also easy to cause...

Abstract

The invention relates to a car instrument panel crossbeam. The car instrument panel crossbeam is connected with a front-wall zone of a car body. A structure connected to the front-wall zone of the car body comprises a crumple zone, a breaking zone and a maintaining zone; the crumple zone is connected with the car-body front-wall zone and is suitable for receiving an impact force transferred by virtue of the car-body front-wall zone; the breaking zone is respectively connected with the crumple zone and the maintaining zone and suitable for being broken when the crumple zone receives the impact force transferred via the car-body front-wall zone; the end surface of the end, connected with the breaking zone, of the maintaining zone is larger than that of the end, connected with the breaking zone, of the crumple zone; the maintaining zone is suitable for containing the crumple zone when the breaking zone is broken. By virtue of the car instrument panel crossbeam, the safety performance of a car can be improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile dashboard beam. Background technique [0002] The car dashboard beam is the internal skeleton of the dashboard system, which is located between the left and right A-pillars in the passenger compartment in the car. It can provide installation location and support for other systems and components in the cockpit. At the same time, as a connecting bracket between the instrument panel system and the body assembly, it can also increase the strength of the entire body and effectively protect the occupants in the event of a vehicle collision. Therefore, its strength and stiffness are the primary indicators of its performance. [0003] In the dashboard cross member, the structure that supports the steering column of the car is connected to the body assembly. Specifically, the cowl area that is attached to the body, such as the windshield lower cross membe...
