Embodiment Construction

[0017] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the present invention provides an instrument panel airbag weakening structure. The weakening structure is a closed weakening groove processed on the instrument panel 1 corresponding to the airbag. The weakening groove includes end-to-end ring-shaped first a transverse section 2, a first vertical section 3, a second transverse section 4 and a second vertical section 5, figure 1 Several sidelines of the middle weakening groove are chamfered structures, which will not be described in detail here. For the convenience of description, the chamfered structures are not drawn in other figures.

[0019] Such as Figure 2 to Figure 3 As shown, the first vertical section 3 and the second vertical section 5 are continuous weakening grooves 6. Here, the continuous weakening grooves in the first vertical section 3 are taken as an...

Abstract

The present invention relates to the technical field of instrument panels, in particular to an instrument panel airbag weakening structure. The weakening structure is a closed weakening groove processed on the instrument panel corresponding to the airbag. The first horizontal section, the first vertical section, the second horizontal section and the second vertical section, the first vertical section and the second vertical section are continuous weakening grooves, and the first horizontal section and the second horizontal section It is an interval weakening groove, and a reinforcing rib is provided between two adjacent interval weakening grooves. The invention has simple structure, convenient processing, and saves processing cost and period. The use of this weakened structure ensures that the airbag of the instrument panel can be blasted smoothly at high temperature, low temperature, and normal temperature without the risk of hard debris splashes and hard splashes, and at the same time ensures the overall strength of the structure; The safety factor of the car user will not affect other technical indicators of the instrument panel.

Description

technical field [0001] The invention relates to the technical field of instrument panels, in particular to an instrument panel safety airbag weakening structure. Background technique [0002] For the safety of people on board, vehicle airbags have been widely used in the automotive industry. When impacted, the airbag pops up to protect people on board. At present, airbags are generally installed under the instrument panel. When the instrument panel is in effect, the airbag of the airbag will tear the instrument panel from the weakened part, so that the airbag of the airbag can be smoothly deployed to protect the head of the occupant. And there must be no hard debris splashes flying out to injure the occupants. However, the existing instrument panel airbag structure is inconvenient to process, and there is a risk of hard splashes flying out. Contents of the invention [0003] The object of the present invention is to provide an instrument panel safety airbag weakening str...
