Description
Technical field
The present invention relates to the decorative cover of a kind of air bag being arranged on vehicle steering.
Background technology
Existing air bag decorative cover is provided with line of weakness structure, upon deployment of the airbag, decorative cover tears from tear line position, owing to the material thickness of tear line position is thinner than periphery material thickness, the width of tear line is narrow, so easily producing injection shrink mark on the surface of injection moulding process middle decorating cover, affect the appearance quality of decorative cover.
Summary of the invention
The purpose of the present invention overcomes drawbacks described above exactly, it is provided that a kind of decorative cover being arranged on air bag, it is easy to open, and improves the appearance quality in decorative cover A face.
The technical solution of the present invention is:
The decorative cover of this air bag being arranged on vehicle steering, including decorative cover body, is provided with square sipes and forms weakening structure in decorative cover rear body centre position, and square sipes both sides are provided with two short line of weakness, and decorative cover body perimeter is provided with capitate groove.
Described decorative cover body perimeter is additionally provided with gathering sill.
The invention has the beneficial effects as follows: change the mode of conventional security airbag deployment, on decorative cover, do not use the design of decorative cover tear line, the weakening structure of square sipes it is provided with as renovating rotating shaft after decorative cover, the material thickness ratio of square sipes is relatively thin, during renovating, play the effect of a rotating shaft, use flip structure, decorative cover periphery to be filled by capitate groove and capitate head card with airbag housing, change the mode of conventional security airbag deployment, it is easy to open；Meanwhile, the both sides of sipes are provided with two short line of weakness, owing to, after decorative cover, even if there being injection shrink mark, also not interfering with the surface quality of decorative cover.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, decorative cover body 5 rear portion is provided with square sipes 1 and forms weakening structure, the left and right sides of square sipes 1 is provided with two short line of weakness 2L and 2R, it is provided with backboard 3 on rear side of square sipes 1, decorative cover body 5 is connected as a single entity by square sipes 1 with backboard 3, the left and right sides of square sipes 1 is provided with two short line of weakness 2L and 2R, decorative cover body 5 periphery is provided with decorative cover enclosure wall 4, backboard 3 and decorative cover enclosure wall 4 are perpendicular to decorative cover body 5 surface, backboard 3 is provided with square hole 3A, and decorative cover enclosure wall 4 is provided with multiple capitate groove 4A, gathering sill 4B.
As shown in Figure 4, the material thickness D1 of square sipes 1 is thinner than the material thickness D2 of its periphery；As it is shown in figure 5, short line of weakness 2R cross section triangularity, the base material thickness D3 of short line of weakness 2R is thin compared with the material thickness D4 of its periphery.The shape of short line of weakness 2L is identical with short line of weakness 2R.
As shown in Figure 6, Figure 7, during installation, the backboard 3 of this decorative cover is assembled together with airbag housing 6, and the boss 6A clamping on the square hole 3A on the backboard 3 of decorative cover and airbag housing 6.
As shown in Fig. 8, Fig. 9 and Figure 10, decorative cover enclosure wall 4 is connected with the periphery of airbag housing 6, capitate groove 4A on decorative cover enclosure wall 4 forms multiple buckle structure with the capitate head 6B phase clamping on airbag housing 6, and guide ledges 6C on airbag housing 6 is inserted in the gathering sill 4B on decorative cover enclosure wall 4.
As shown in figure 11, when air bag point is quick-fried, safety air bag inflation in airbag housing 6 expands, thrust F1 promotes decorative cover, owing to airbag housing 6 maintains static, the periphery shackle portion relative motion (dotted line direction motion as shown in Figure 7) of decorative cover enclosure wall 4 and airbag housing 6, wherein, capitate head 6B ramp produces F2 power and the capitate groove 4A of decorative cover is strutted.The capitate groove 4A of final decorative cover departs from the capitate head 6B of housing 6.
As shown in figure 12, owing to square sipes 1 thickness of decorative cover is thin, after the capitate groove 4A of decorative cover departs from the capitate head 6B of airbag housing 6, square sipes 1 yield deformation, and as rotating shaft, decorative cover begins turning.Meanwhile, in decorative cover switching process, two short line of weakness 2L on decorative cover and 2R tear.
