Abstract
The utility model relates to an automobile safety air cell extension plate, which is provided with an extension plate mainbody and an extension plate frame; the extension plate mainbody is connected in the extension plate frame by a hinge; the extension plate frame is fixedly connected at the position of an automobile instrument panel body where a safety air cell module is correspondingly arranged. The extension plate mainbody is provided with counterbores by which the extension plate mainbody and the instrument panel body are pivoted together; the counterbores are uniformly arranged on the extension plate mainbody, thus leading the extension plate to be completely attached to and fixedly connected with the instrument panel frame. The extension plate frame is fixedly connected on the automobile instrument panel body by a projection welding nut. The extension plate and the extension plate frame are made of steels. The automobile safety air cell extension plate adopts a composite plate structure that a turnover hinge is matched with the frame structure; the extension plate and the extension plate frame are made of steels; the extension plate and the instrument panel are designed in a pivoting way; the structure ensures the position stability and the installation reliability of the extension plate, reinforces the guide function of the air cell and improves the stability of the guide by the arrangement of the hinge.
Description
Technical field
The utility model relates to safe automobile air bag, is specifically related to the deployed configuration of safe automobile air bag.
Background technology
Moulded attractive in appearance in order to guarantee, what present most of luxury car copilot station adopted is hidden type safety air bag, and promptly observed from the outside is a single-piece instrument carrier panel, does not have independent airbag cover.The instrument carrier panel of the type is generally three layers: injection moulding casing play, foaming layer, covering layer.And cooresponding conventional airbag structure has two kinds:
(1) leave the macropore that can put into air bag module on instrument board framework, the air bag module band that plastics expansion plate integral installation is fitted on the skeleton and is fixing, instrument carrier panel is foamed and covering again;
(2) instrument board framework wide-bore not marks the cooresponding zone of air bag module separately, and by the injection moulding mode an independent expansion plate and this zone is connected to one when the injection moulding skeleton, instrument carrier panel is foamed and covering again, assembles air bag module at last.
First kind of mode although line of weakness is arranged, because the expansion plate outside also has foaming layer and covering layer, causes the guidance quality of expansion plate in airbag deployment to be difficult to control because the airbag deployment plate is a Plastic Parts.The reliability of Plastic Parts is also relatively poor simultaneously.
Skeleton is to be connected by injection moulding with expansion plate in the second way, and when airbag deployment, expansion plate will drive the skeleton upset of instrument carrier panel corresponding region.Because skeleton is a rigid plastic spare, might relatedly cause that the instrument board framework of neighboring area splits, and influences the normal expansion of air bag this moment.Though guide function is compared first kind of mode reinforcement is arranged, have the unsettled situation of upset.
Summary of the invention
The purpose of this utility model is the above-mentioned many deficiencies at the prior art existence, a kind of safe automobile air bag expansion plate is proposed, strengthen connection reliability with instrument carrier panel injection moulding skeleton, guidance quality is better upon deployment to make safety air bag, the stability of instrument board framework is better during airbag deployment, improves the assembly reliability of air bag module simultaneously.
The technical solution of the utility model is as follows:
The safe automobile air bag expansion plate, it has an expansion plate main body and an expansion plate frame, described expansion plate main body is connected through the hinge in the expansion plate frame, and described expansion plate lateral frame board is fixedly connected on the corresponding position that air bag module is installed on the Automobile instrument body.
Described expansion plate main body is provided with counterbore, by counterbore expansion plate main body and instrument carrier panel body is riveted together, and counterbore is rectangular distribution on the expansion plate main body, makes expansion plate fit fully with instrument board framework and firmly be connected.
Described expansion plate frame is fixedly connected on the Automobile instrument body by project-welding nut.
Described expansion plate is the square arc of a block length, and expansion plate and expansion plate frame are by the steel part material.
The utility model has adopted turnover hinge to cooperate the composite plate structure of framed structure, expansion plate and expansion plate frame are used steel and are made, expansion plate and instrument carrier panel adopt the riveted joint design, such structure had both guaranteed the positional stability and the installation reliability of expansion plate, strengthened guide function again, and improved the stability of guiding by being provided with of hinge air bag.

Fig. 3: expansion plate work scheme drawing
Wherein, 1-expansion plate body; The straight hinge of 2-; 3-expansion plate frame; 4-projection welding bolt; The 5-counterbore; 6-instrument carrier panel body
The specific embodiment
Referring to Fig. 1, the air-bag deployment plate comprises expansion plate body 1 and expansion plate frame 3, by the steel part material.Expansion plate body 1 is positioned at expansion plate frame 3, and both connect by three straight hinges 2, and whole expansion plate body is nearly rectangular arc, evenly is provided with six counterbores 5 on the expansion plate body 1, and expansion plate frame 3 is provided with projection welding bolt 4.
Referring to Fig. 2, during installation, expansion plate frame 3 is captiveed joint with instrument carrier panel body 6 by projection welding bolt 4.Expansion plate body 1 is connected with expansion plate frame 3 by straight hinge 2, and is riveted on the instrument carrier panel body 6 by six counterbores, to the processing of foaming of instrument carrier panel integral body, finishes the covering operation then, makes expansion plate be in the middle foaming layer of instrument carrier panel.
Referring to Fig. 3, when air bag was worked, airbag deployment pushed up the instrument board framework correspondence position, and expansion plate body 1 is subjected to straight hinge 2 controls, drove the corresponding skeleton upset of instrument carrier panel thereupon, split.In 1 switching process of expansion plate body, drive foaming layer simultaneously and covering is torn, for airbag deployment is opened up output direction and space.In this process, because three straight hinge controls are arranged, the reverses direction of expansion plate body 1 and upset space are in controllable state always, and guiding can not make a mistake.And owing to there is projection welding bolt 4 to connect, expansion plate frame 3 also firmly links together with the instrument carrier panel body, can not make 1 whole disengaging of expansion plate body because of air bag impacts.
