Description

A kind ofly mould concealed secondary air bag cover plate structure firmly

Technical field

The utility model relates to secondary airbag cover reduction of a kind of Automobile instrument and welded structure design, is a kind of hidden type safety air bag covering plate structure.

Background technology

1. the secondary safety air bag on the Automobile instrument of present A level car all is bright airbag structure basically; This structure a glance just can be seen the air bag cover plate; Very not attractive in appearance, and the air bag cover plate is installed on the right body of instrument carrier panel and exists gap and face poor between two parts, and these positions are easy to pile up dust.

2. the secondary safety air bag on the present Automobile instrument just develops towards the hidden type safety air bag direction; Except the safety air bag sign, do not see that basically there is safety air bag at this position on the hidden type safety air bag cover plate; This design does not influence outward appearance, makes the right body of instrument carrier panel keep the complete and attractive in appearance of its profile.

The utility model content

In order to keep complete and attractive in appearance on right this body profile of Automobile instrument; The utility model provides a kind of concealed secondary air bag cover plate structure; This kind structure had both kept the complete and attractive in appearance of right this body profile of instrument carrier panel; Safety air bag can eject smoothly after guaranteeing the air bag explosion again, guarantees occupant's safety from face.

To achieve these goals; The technical scheme of the utility model is: a kind of concealed secondary air bag cover plate structure of moulding firmly is provided; Comprise the right body of air bag plastic stent and instrument carrier panel; Wherein, the right body of said air bag plastic stent and instrument carrier panel is welded into an integral body, and said air bag plastic stent comprises that hinge, the wide cross section of narrow root, top are the trapezoidal welding muscle and the outer turning cover of air bag plastic stent; The right body of said instrument carrier panel comprises on reduction groove and the right body of instrument carrier panel from the open circuited part of reduction groove; Around the periphery of said air bag plastic stent with the right body of instrument carrier panel at the reduction groove with external welding; Weld from the open circuited part of reduction groove on the right body of the outer turning cover of air bag plastic stent and instrument carrier panel; The right body of instrument carrier panel is from the fracture of reduction groove location during the air bag explosion, on the outer turning cover of air bag plastic stent and the right body of instrument carrier panel from the open circuited part of groove that weakens do as a whole around hinge to turning up.

Said hinge adopts the serpentine structure, and the right body of air bag plastic stent and instrument carrier panel adopts the vibration friction to be welded into an integral body.

The beneficial effect of the utility model is: 1, guaranteed safety air bag smoothly explosion eject and do not produce chip etc. and be prone to hurt occupant's foreign matter, thereby guarantee occupant's safety; 2, the residual thickness of reduction groove is controlled in the reasonable range, from can't see rough impression in appearance basically, guarantees the complete and attractive in appearance of right this body profile of instrument carrier panel, the basic no change of outward appearance in the long-term use process after the entrucking; 3, the reduction groove adopts milling cutter processing, and equipment investment is few, economizes on the use of funds.

But Fig. 1,2,3,4,5,6 knowledge capital utility models by on the outer turning cover of 1 expression air bag plastic stent, 2 expression hinges, 3 expression welding muscle, 4 expression air bag plastic stents, the right bodies of 5 expression instrument carrier panels, 6 expression reduction grooves, the right bodies of 7 expression instrument carrier panels from the open circuited part of reduction groove.

The specific embodiment

Mould the technology contents of concealed secondary air bag cover plate structure, structural attitude firmly, be described further in order to specify the utility model below in conjunction with embodiment and conjunction with figs..

Like Fig. 1,2,3,4,5, shown in 6; The utility model is moulded concealed secondary air bag cover plate structure firmly and is comprised the right body 5 of air bag plastic stent 1 and instrument carrier panel; Wherein, Said air bag plastic stent 1 is welded into an integral body with the right body 5 of instrument carrier panel, and said air bag plastic stent 1 comprises that hinge 2, the wide cross section of narrow root, top are the trapezoidal welding muscle 3 and the outer turning cover 4 of air bag plastic stent; The right body 5 of said instrument carrier panel comprises on reduction groove 6 and the right body of instrument carrier panel from the open circuited part 7 of reduction groove; Around the periphery of said air bag plastic stent 1 with the right body 5 of instrument carrier panel at reduction groove 6 with external welding; Weld from the open circuited part 7 of reduction groove on the right body of the outer turning cover 4 of air bag plastic stent and instrument carrier panel; The right body 5 of instrument carrier panel is from the 6 positions fracture of reduction groove during the air bag explosion, on the outer turning cover 4 of air bag plastic stent and the right body of instrument carrier panel from the open circuited part 7 of reduction groove do as a whole around hinge to turning up.

Said hinge adopts the serpentine structure, and air bag plastic stent 1 adopts the vibration friction to be welded into an integral body with the right body 5 of instrument carrier panel.

The wide cross section of narrow root, welding muscle 3 employing tops on the air bag plastic stent 1 is that trapezoidal welding muscle does not produce impression to guarantee the welding back right body weakened location of instrument carrier panel; Welding muscle simultaneously needs science to distribute by the weld strength at each position, guarantees after the air bag explosion on the right body of instrument carrier panel can not separate with the outer turning cover 4 of air bag plastic stent from the open circuited part 7 of reduction groove to fly out.Hinge 2 adopts the serpentine structure to guarantee the length long enough of hinge, guarantees that air bag explosion rear gasbag lid turns up Shi Buhui because hinge length is torn hinge inadequately.

Can clearly be seen that from Fig. 3 Fig. 4 the safety air bag position mills out a rectangular reduction groove 6 on the right body 5 of instrument carrier panel, rectangular four angles are arc transition, and the reduction groove is from the open circuited part 7 of reduction groove on the right body of instrument carrier panel with interior part.

Can clearly be seen that from Fig. 5 Fig. 6 the right body 5 of air bag plastic stent 1 and instrument carrier panel is welded into an integral body; Around the periphery of air bag plastic stent 1 with the right body 5 of instrument carrier panel at the reduction groove with external welding; Weld from the open circuited part 7 of reduction groove on the right body of the outer turning cover 4 of air bag plastic stent and instrument carrier panel; The right body 5 of instrument carrier panel is from the 6 positions fracture of reduction groove during the air bag explosion; On the outer turning cover 4 of air bag plastic stent and the right body of instrument carrier panel from the open circuited part 7 of reduction groove do as a whole around hinge 2 to turning up; The hinge of serpentine structure is guaranteed the length long enough of hinge, guarantees that the airbag cover Shi Buhui that turns up tears hinge because hinge length is not enough, thereby guarantees occupant's safety.Said hinge adopts the serpentine structure; The residual thickness on three limits that the borehole blasting of reduction groove is torn is 0.5mm; That limit at the hinge position that airbag cover is turned up and the residual thickness on four circular arc limits are 0.8mm, and air bag plastic stent 1 adopts the vibration friction to be welded into an integral body with the right body 5 of instrument carrier panel.

The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
