Abstract
The utility model discloses a flexible plastic hidden type auxiliary airbag cover plate hinge structure. The flexible plastic hidden type auxiliary airbag cover plate hinge structure comprises an auxiliary airbag cover plate (3), a hinge (1), weakening grooves (2) and turnover weakening grooves (4), and is characterized in that each weakening groove (2) which extends outwards to the side wall is formed in each of two ends of the hinge (1); the inward end of each weakening groove (2) is arc-shaped; the symmetric turnover weakening grooves (4) are formed in parts, corresponding to the hinge (1), outside the auxiliary airbag cover plate (3). The flexible plastic hidden type auxiliary airbag cover plate hinge structure has the advantages of simple structure, convenience, practicality, safety and reliability; when an auxiliary airbag is burst, the auxiliary airbag cover plate is easily turned over outwards and cannot be broken to fly out, so that the safety of passengers is guaranteed.
Description
Technical field
The utility model relates to a kind of secondary airbag device, relates to specifically a kind of soft hidden auxiliary airbag cover hinge arrangement of moulding, and is applied to foaming layer while preventing secondary safety air bag explosion and flies out with cover plate disengaging.
Background technology
At present, Automobile instrument more than B level is all the soft instrument carrier panel of moulding substantially, secondary safety air bag on instrument carrier panel is all hidden type safety air bag substantially, when soft secondary safety air bag explosion of moulding foaming, foaming layer is outwards overturn by hinge position with interior part with secondary airbag cover hinge together with foaming layer, in the time that hinge design is unreasonable, secondary airbag cover or very difficult outwards upset, or be easy to fracture from hinge position, fly out at a high speed, affect occupant's safety.
Summary of the invention
The deficiency existing in order to overcome above technology, the utility model provides a kind of hidden auxiliary airbag cover hinge arrangement.
The technical solution adopted in the utility model is: a kind of soft hidden auxiliary airbag cover hinge arrangement of moulding, it comprises that secondary airbag cover, hinge, reduction groove, upset weaken groove, it is characterized in that: described hinge two ends are respectively provided with respectively a reduction groove that extends outwardly into sidewall, the inside one end of described reduction groove is arcuation; The outside corresponding hinge position of described secondary airbag cover is provided with symmetrical upset and weakens groove.
Described upset weakens the degree of depth of groove and guarantees that to the minimum wall thickness (MINI W.) at described hinge position be 2.0mm～2.4mm.
The degree of depth that preferred described upset weakens groove guarantees that to the minimum wall thickness (MINI W.) at described hinge position be 2.2mm.
The straight-line distance that described upset weakens groove two ends and inner reduction groove is 4mm～8mm.
The straight-line distance that preferred described upset weakens groove two ends and inner reduction groove is 6mm.
Described reduction slot length is 23mm～27mm, and thickness is 0.3mm～0.7mm.
Preferred described reduction slot length is 25mm, and thickness is 0.5mm.
The beneficial effects of the utility model are: not only simple in structure, convenient and practical, safe and reliable, and easily outwards upset and can not fracture and fly out of secondary airbag cover while having ensured secondary safety air bag explosion, guarantee occupant's safety.
