Problems solved by technology

Since the frame is a hard plastic part, it may cause the frame of the instrument panel in the surrounding area to crack at this time, affecting the normal deployment of the airbag
Although the guiding function has been strengthened compared with the first method, there is a situation where the flip is unstable

Embodiment Construction

[0018] Referring to Fig. 1, the airbag composite deployment panel includes a deployment panel body 1 and a deployment panel frame 3, which are made of steel materials. The expansion plate body 1 is located in the expansion plate frame 3, and the two are connected by three straight hinges 2. The entire expansion plate body is a nearly rectangular arc-shaped plate, and six counterbores 5 are uniformly arranged on the expansion plate body 1. Projection welding bolts 4 are arranged on the frame 3 .

[0019] Referring to FIG. 2 , during installation, the frame 3 of the unfolded panel is fixedly connected with the instrument panel body 6 through projection welding bolts 4 . The expansion panel body 1 is connected with the expansion panel frame 3 through a straight hinge 2, and riveted to the instrument panel body 6 through six countersunk holes, and then the entire instrument panel is foamed to complete the skinning process, so that the expansion panel is placed on the instrument pa...

Abstract

The invention relates to a complex type unfolding plate of vehicle safety air chamber comprising a main body of unfolding plate and a frame of unfolding plate. The main body of the unfolding plate is connected with the frame of the unfolding plate by hinge. The frame of the unfolding plate is permanently connected to the position of mounting air chamber module corresponding with the main body of fascia. A counter bore is in the main body of the unfolding plate and the main body is connected with the body of the fascia by the counter bore. The counter bores are evenly dispersed on the main body of the unfolding plate to make the unfolding plate and skeleton of the fascia completely jointed with each other. The frame of the unfolding plate is permanently connected with the main body of the fascia by projection weld nut. The unfolding plate and the frame are produced by steel material. The invention uses composite plate structure of overturning hinge cooperation frame structure. The unfolding plate and the frame thereof are produced by steel material. The unfolding plate and the fascia use design of rivet joint. The structure can ensure the stability of position of the unfolding plate and the mounting reliability and strength the guiding function of the air chamber and increase the stability of guiding by the hinge.

Description

technical field [0001] The invention relates to an automobile safety air bag, in particular to a deployment structure of the automobile safety air bag. Background technique [0002] In order to ensure the beauty of the overall shape, most of the high-end cars currently use a hidden airbag for the co-pilot position, that is, a whole instrument panel is observed from the outside without a separate airbag cover. This type of instrument panel generally has three layers: injection molding skeleton layer, foam layer and skin layer. There are two corresponding conventional airbag structures: [0003] (1) Open a large hole on the frame of the instrument panel that can be put into the airbag module. The airbag module is assembled on the frame with a plastic expansion plate and fixed, and then the instrument panel is foamed and skinned; [0004] (2) The frame of the instrument panel does not open large holes, and the area corresponding to the airbag module is drawn separately when i...
