Abstract
The utility model relates to the field of air bag restraint system devices of automobiles, in particular to an air bag strengthening frame structure for passengers. The air bag strengthening frame structure consists of a strengthening frame body and an air bag door cover, the air bag door cover consists of a door cover frame, a first door cover and a second door cover, downwards concave V-shaped transitional connecting sections are arranged at connection portions of the two door covers and the door cover frame, V-shaped bottoms of the transitional connecting sections are in arc transition, and the transitional connecting sections are in arc transitional connection with the door cover frame and the two door covers. The air bag strengthening frame structure for passengers resolves technical problems that in the prior art, connection rigid of door covers and door cover frames is high while breakage strength thereof is low, the door covers and the door cover frames which are connected are easy to be completely separated when air bag restraint systems for passengers are exploded, and the door covers are easy to drop and splash to injure the passengers. The connection portions of the door covers and the door cover frame are high in flexible deformation quantity, the door covers and the door cover frame which are connected are not easy to be separated completely, and accordingly safety protection property of an air bag restraint system for passengers is improved.
Description
Technical field
The utility model relates to the Automotive Safety Air Bags field, especially relates to a kind of occupant's air bag reinforced bulkhead structure.
Background technology
The vehicle occupant safety air bag leaves in occupant's air bag reinforced bulkhead.Occupant's air bag reinforced bulkhead constitutes by the reinforced bulkhead body with air bag door closure that the reinforced bulkhead body is connected.The air bag door closure of prior art occupant's air bag reinforced bulkhead directly punches out H shape joint-cutting by an arc and makes, be divided into the door closure frame, first door closure and second door closure, three parts are formed, the upper surface of air bag door closure is provided with the connection structure that links to each other with instrument carrier panel, wherein first door closure and second door closure and door closure frame coupling stiffness height, disruption characteristic is low, detonate when going out occupant's air bag reinforced bulkhead at passenger airbag, first door closure and second door closure turn up around the connecting portion of they and door closure frame, first door closure and second door closure are connected with the door closure frame and are prone to fracture fully, cause first door closure or second door closure casualty accident that splashes that comes off.
Summary of the invention
The utility model mainly is to solve existing in prior technology first door closure and second door closure and door closure frame coupling stiffness height, disruption characteristic is low, passenger airbag detonates, and this connection is prone to fracture fully when going out occupant's air bag reinforced bulkhead, cause first door closure or second door closure to come off to splash the door closure technical matters of casualty accident, provide a kind of simple in structure, be easy to make, first door closure with are not prone to second door closure and being connected of door closure frame the occupant's air bag reinforced bulkhead structure that ruptures fully.
The used technical scheme of the utility model is: a kind of occupant's air bag reinforced bulkhead structure, constitute by the reinforced bulkhead body with air bag door closure that the reinforced bulkhead body is connected, wherein the air bag door closure is made up of door closure frame, first door closure and second door closure, it is characterized in that: first door closure is provided with recessed transition linkage section with the position that second door closure links to each other with the door closure frame.
The utility model, by described transition linkage section, reduced the coupling stiffness of first door closure and second door closure and door closure framework, strengthened the plastic deformation amount of first door closure and second door closure and door closure framework connecting portion when passenger airbag is gone out occupant's air bag reinforced bulkhead, therefore first door closure does not rupture with being prone to second door closure and being connected of door closure frame fully, thereby has improved the safety precaution performance of passenger airbag device.
As preferably, the transversal surface of described transition linkage section is in the shape of the letter V, the recessed A/F of the vee shape of transition linkage section be 10mm to 15mm, the ratio of the A/F and the degree of depth is that 1:1 is to 1:2.This preferred version, the transition linkage segment structure is reasonable, makes handling ease, to the normal storage of member's safety air bag with detonate and do not have adverse effect.
As preferably, the V word of the vee shape transversal surface of described transition linkage section bottom arc transition; The transition linkage section is connected with door closure frame, first door closure, the equal arc transition of second door closure.This preferred version, the stress deformation form was reasonable when two door closures turned up, and helped improving door closure and door closure frame Joint strenght.
As preferably, described reinforced bulkhead body and air bag door closure are made by modified polypropene.This preferred version, reinforced bulkhead body and door closure feed stock cost are low, in light weight, intensity is high, help reducing vehicle weight, reduce automobile fuel consumption.
As mentioned above, the beneficial effect that brings of the present utility model is: by recessed transition linkage section is set, reduced the coupling stiffness of first door closure and second door closure and door closure framework, strengthened the plastic deformation amount of first door closure and second door closure and door closure framework connecting portion when passenger airbag is gone out occupant's air bag reinforced bulkhead, first door closure does not rupture with being prone to second door closure and being connected of door closure frame fully, thereby has improved the safety precaution performance of passenger airbag device.
The utlity model has rational in infrastructure, easy to manufacture, low, the lightweight characteristics of feed stock cost.
