Abstract

The invention discloses a crossbeam assembly used for an automobile instrument board. The crossbeam assembly comprises a crossbeam assembly body. The crossbeam assembly body comprises a main tubular beam, a first end support, a first longitudinal support, a second longitudinal support and a second end support, wherein the first end support, the first longitudinal support, the second longitudinal support and the second end support are sequentially arranged on the main tubular beam at intervals; a third end support is arranged between the first end support and the first longitudinal support; thefirst longitudinal support and the second longitudinal support are oppositely arranged, extend to the same side and are opposite to the third end support in the extension direction; the side, opposite to the third end support, of the main tubular beam is provided with a steering tubular column connecting support; the connecting position of the main tubular beam and the second longitudinal supportis provided with an electronic module connecting support; the free end of the second longitudinal support is connected with an automobile body floor connecting support; an air bag connecting supportand a glove box connecting support are arranged between the second longitudinal support and the second end support; and the main tubular beam, the first longitudinal support, the second longitudinal support, the first end support, the second end support and the third end support are manufactured through an integrated injection molding process. The provided crossbeam assembly used for the automobile instrument board has sufficient structural strength.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, and more specifically, relates to a beam assembly for an automobile instrument panel. Background technique [0002] Based on the internal structure of most current models, the instrument panel beam installed in the front cabin of the driver acts as a load-bearing part to provide stable support for the surrounding environment such as airbags, steering column and steering wheel, air conditioning assembly, instrument panel assembly and its accessories. Support and correct installation interface, and at the same time constitute a safety system with other safety parts to protect the safety of the driver and passengers. [0003] As a vehicle frame member and a key part of the passive safety of car occupants, the instrument panel beam needs to have sufficient rigidity; when the car collides, it needs to have a certain energy absorption effect. Therefore, the instrument panel beam needs ...
