Embedding riveting bracket for connecting automobile interior instrument board with safe air bag cabin

Abstract

The invention discloses an embedding riveting bracket for connecting an automobile interior instrument board with a safe air bag cabin and a method for connecting the embedding riveting bracket with the interior instrument board. A technical scheme is that: a plurality of perforations for connection are formed on the embedding riveting bracket; counter bores for forming snaps during injection moulding are formed on a mould core of an injection mould of the interior instrument board opposite to the perforations; and the embedding riveting bracket serving as an insert is embedded in the injection mould of the interior instrument board, so that the embedding riveting bracket is connected with the interior instrument board into a whole in an embedding riveting way along with the injection moulding of the interior instrument board. The embedding riveting bracket solves the problems of undetermined reliability, difficult detection and high manufacturing cost in the prior art. The embedding riveting bracket for connecting the automobile interior instrument board with the safe air bag cabin provided by the invention enables the connection of the bracket and the interior instrument board to get rid of the disadvantage of ultrasonic welding through an injection moulding embedding riveting connection mode and fulfils the aims of connecting reliably, detecting easily and reducing cost.

Description

technical field [0001] The invention relates to a connection structure of an automobile interior dashboard, in particular to an embedded riveting bracket for connecting and fixing a safety airbag chamber on the automobile interior dashboard. Background technique [0002] The airbag compartment is a metal box-shaped container for the car airbag; the airbag compartment is fixed on the inner side of the car interior dashboard, and the fixing of the airbag compartment requires sufficient strength to resist the instantaneous expansion of the gas when the airbag is detonated. The recoil force makes the airbag break through the weakened area on the surface of the interior dashboard and eject forward, protecting the lives of the drivers and passengers. [0003] The airbag compartment is fixed on the interior trim panel by a plastic connection bracket with bolts, and the prior art connection bracket and the interior trim panel are connected by ultrasonic welding; The connection stre...

AI Technical Summary

Problems solved by technology

[0003] The airbag compartment is fixed on the interior trim panel by a plastic connection bracket with bolts, and the prior art connection bracket and the interior trim panel are connected by ultrasonic welding; The connection strength depends on the reliability of the ultrasonic welding quality of the interior instrument panel and the connecting bracket. The reliability detection of the ultrasonic welding quality requires destructive testing. The destructive testing can only be used for random inspection in actual production, and it is impossible to conduct a full inspection. This makes the connection between the connecting bracket and the interior instrument panel a latent quality hazard of uncertain welding reliability; in addition, ultrasonic welding will affect the surface appearance quality of the interior instrument panel, so that the surface appearance of the interior instrument panel needs to be "covered". "Leather" process is used to cover and decorate, which increases the manufacturing cost of the interior instrument panel; therefore, the existing technology has the problems and deficiencies of uncertain welding reliability, difficulty in detection, and high manufacturing cost
