For achieving the above object, the utility model adopts following technical proposals.
A kind of air bag cover, comprise the air bag cover body, described air bag cover body comprises the detonating fuse groove and is arranged at the cover plate at air bag cover body middle part, one end of described detonating fuse groove links to each other with cover plate, described air bag cover body convexes with reinforced rib, and described reinforced rib is located in the terminal outer rim of detonating fuse groove.
Wherein, the detonating fuse groove is provided with reinforced rib away from the lower peripheral of cover plate.
Wherein, the bottom of detonating fuse groove is curved.
Wherein, the end of detonating fuse groove is provided with spherical recess.
Wherein, the intersection of reinforced rib and air bag cover body is provided with the arc lead angle.
Wherein, the air bag cover body is provided with at least two detonating fuse grooves.
Wherein, reinforced rib and this body by integral forming of air bag cover.
The utility model beneficial effect is: the utility model comprises the air bag cover body, described air bag cover body comprises the detonating fuse groove and is arranged at the cover plate at air bag cover body middle part, one end of described detonating fuse groove links to each other with cover plate, described air bag cover body convexes with reinforced rib, and described reinforced rib is located in the terminal outer rim of detonating fuse groove; Reinforced rib the structural strength that has improved the detonating fuse notch end is set; avoid breaking of air bag cover to exceed the distal portion of detonating fuse groove; effectively avoid the end of detonating fuse groove when explosion, to produce wedge angle and puncture safety air bag; demolition effect is good; conscientiously the protection occupant escapes injury or alleviates extent of injury, safety performance height.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of air bag cover of the utility model;
Fig. 2 is the structural representation at another visual angle of a kind of air bag cover of the utility model;
Fig. 3 is the structure enlarged diagram of A position among Fig. 1;
Fig. 4 is the structure enlarged diagram of B position among Fig. 2.
In Fig. 1, Fig. 2, Fig. 3 and Fig. 4, include:
1---the air bag cover body; 2---the detonating fuse groove;
3---cover plate; 4---reinforced rib;
5---spherical recess.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model comprises air bag cover body 1, described air bag cover body 1 comprises detonating fuse groove 2 and is arranged at the cover plate 3 at air bag cover body 1 middle part, one end of described detonating fuse groove 2 links to each other with cover plate 3, described air bag cover body 1 convexes with reinforced rib 4, and described reinforced rib 4 is located in the terminal outer rim of detonating fuse groove 2.
When vehicle body is subjected to clashing, gas-bag system will cause the chemical reaction of similar low dose of explosive charge, detonating fuse groove 2 and cover plate 3 all break, the safety air bag that is hidden in cover plate 3 belows is just in moment inflation ejection, before occupant's health and in-vehicle device collision, play the place mat effect, alleviate the suffered impulsive force of health, alleviate the effect that the occupant is hurt thereby reach.
End at detonating fuse groove 2 encloses reinforced rib 4, improved the structural strength of detonating fuse groove 2 ends, the power of avoiding being produced because of gas-bag system moment explosion makes breaking of air bag cover exceed the distal portion of detonating fuse groove 2 greatly, guarantee that safety air bag air bag cover when explosion excessively breaks at detonating fuse groove 2 ends, effectively avoid the end of detonating fuse groove 2 when explosion, to produce wedge angle and puncture safety air bag, improved the reliability of service of safety air bag, the safety performance height.In addition, the setting of reinforced rib 4 is come out safety air bag smoothly from cover plate 3 borehole blasting, is convenient to realize the demolition effect of expecting, guarantees that the demolition effect of safety air bag is good.
Detonating fuse groove 2 of the present utility model is provided with reinforced rib 4 away from the lower peripheral of cover plate 3.Enclose reinforced rib 4 in the bottom of detonating fuse groove 2, improved the structural strength of detonating fuse groove 2 bottoms, guarantee that the explosion of safety air bag does not exceed the position of detonating fuse groove 2 bottoms, prevent that the wedge angle that produces when air bag cover excessively breaks from puncturing safety air bag, improves safety in utilization of the present utility model.
The bottom of detonating fuse groove 2 of the present utility model is curved.The setting of detonating fuse groove 2 curved lower portion, guarantee that air bag cover body 1 is in explosion, the plastic cement fragment of cover plate 3 bottoms remains on the air bag cover body 1, and the plastic cement fragment that effectively alleviates the explosion generation improves safety performance of the present utility model to the injury that the occupant brings.
The end of detonating fuse groove 2 of the present utility model is provided with spherical recess 5.End at detonating fuse groove 2 is provided with spherical recess 5, is equivalent to stop the position in the explosion that detonating fuse groove 2 has been preset for the smooth explosion of safety air bag, provides convenience for the explosion of safety air bag, has improved result of use of the present utility model.
Reinforced rib 4 of the present utility model is provided with the arc lead angle with the intersection of air bag cover body 1.Reinforced rib 4 forms an angle with the intersection of air bag cover body 1, in use, this angle can form focal point of stress, improved under external force reinforced rib 4 from the risk of this angle fracture, it is the point of slick and sly unstressed sudden change that the setting of arc lead angle makes the intersection of reinforced rib 4 and air bag cover body 1, thereby eliminated focal point of stress, further improved service life of the present utility model.
Air bag cover body 1 of the present utility model is provided with at least two detonating fuse grooves 2.Because the position thinner thickness of detonating fuse groove 2 residing air bag cover bodies 1, structural strength is low with respect to the structural strength of other positions of air bag cover body 1, at air bag cover body 1 two detonating fuse grooves 2 are set, increased the burst region of safety air bag, provide convenience for the safety air bag explosion, improve safety performance of the present utility model.Certainly, also can at air bag cover body 1 a plurality of detonating fuse grooves 2 be set as required, when guaranteeing that further vehicle body is subjected to clashing, the smooth explosion of safety air bag is come out, and effectively alleviates occupant's degree that is hurt.
Reinforced rib 4 of the present utility model is one-body molded with air bag cover body 1.Reinforced rib 4 and air bag cover body 1 have reduced production and processing operation of the present utility model, improve work efficiency, reduce production costs.
Certainly, the above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
