Abstract
The utility model provides an internal decorative ceiling of a car. The internal decorative ceiling of the car is provided with groove-shaped continuous weak line structures (2) on two sides of the upper surface. According to the internal decorative ceiling of the car, the weak line structures on the internal decorative ceiling can be served as hinges; and the internal decorative ceiling can be bent along the weak lines under the effect of a bursting force from a side air curtain, so that the side air cushion can be easily released.
Description
Technical field
The utility model relates to field of automobile safety, particularly a kind of automotive trim top.
Background technology
In order to protect occupant safety, car enterprise increases various safety measures for car load, is exactly wherein one as increasing the side gas curtain.The side gas curtain is installed in the space that the side of the interior trim top of automobile, the trim panel adjacent with the interior trim top and vehicle body form.When the collision happens accident, the side gas curtain should be able to be smoothly from the side release of interior trim top, with protection occupant's safety.
Because the employed material of interior trim top has preferably toughness and hardness, if the line of weakness structure design of top is unreasonable, when the side blasting of air curtain, the interior trim top is difficult to deviate from from B post and C post trim panel, cause the side gas curtain can't be discharged into assigned address and ineffective, thereby cause occupant's injury.
Usually the top line of weakness structure of design is discontinuous, and the line of weakness design of discontinuous shape is easy to cause top herein to open.
The utility model content
The technical problems to be solved in the utility model provides a kind of automotive interior roof, and when the collision happens accident, the side gas curtain can discharge from the interior trim top and put in place.
For solving the problems of the technologies described above, embodiment of the present utility model provides technical scheme as follows:
A kind of automotive trim top 1, the both sides of the upper surface of described automotive trim top 1 are provided with the continuous line of weakness structure 2 of groove type.
The trend of the midway location of described line of weakness structure 2 is circular arc.
The shape of cross section of described line of weakness structure 2 is trapezoidal or oblong.
Described trapezoidal be inverted trapezoidal.
Described automotive trim top is for once compressing.
The automotive trim top that the utility model provides has following beneficial effect:
Line of weakness structure on the interior trim top is owing to be continuous structure; can play the effect of hinge; under the effect of side blasting of air curtain power; the interior trim top can be crooked along line of weakness; the side gas curtain is discharged easily; when automobile crashed, the side gas curtain discharged from the interior trim top smoothly, reached the purpose of safety guard-safeguard.
Description of drawings
Fig. 1 is the integrally-built birds-eye view of interior trim top among the utility model embodiment;
Fig. 2 is the scheme drawing of the A-A cross section of interior trim top among Fig. 1.
The specific embodiment
As shown in Figure 1, be automotive trim top 1 described in the utility model, the both sides of the upper surface of described automotive trim top 1 are provided with the continuous line of weakness structure 2 of groove type.
The trend of the midway location of described line of weakness structure 2 can be circular arc.
Certainly, the shape of cross section of described line of weakness structure 2 can be trapezoidal or oblong; As shown in Figure 2, describedly trapezoidally can be inverted trapezoidal, be convenient to the processes in the actual production.
Interior trim top 1 of the present utility model can be in mould disposal pressed moulding.
In above-described embodiment of the present utility model, because line of weakness structure 2 is continuous shape, the line of weakness structure does not disconnect near passenger handrails 3.
In the prior art, adopt the line of weakness design of discontinuous shape, near the line of weakness passenger handrails disconnects.When the space hour, the line of weakness design of discontinuous shape can make the passenger handrails place stressed larger, and owing to do not have the line of weakness structure near the passenger handrails, is easy to cause herein top can't open or cause passenger handrails to be damaged greatly because of stressed.
Interior trim top of the present utility model is particularly useful for because inner space of vehicle is little, causes the very little vehicle of distance between side gas curtain and the passenger handrails.Continuous line of weakness structure is set near the passenger handrails of top; the suffered power of passenger handrails when being conducive to weaken the side blasting of air curtain; passenger handrails is played a protective role, be convenient to simultaneously top by designed line of weakness bending, thereby reach the purpose that allows the side gas curtain launch smoothly.The utility model can not only make the side gas curtain deviate from from the interior trim top smoothly, makes the side gas curtain launch smoothly to put in place; And the line of weakness structure of passenger handrails vicinity has played protective effect to passenger handrails, avoids the damage of passenger handrails.
Automotive trim top of the present utility model also has following beneficial effect:
1. the line of weakness structure on the interior trim top of the present utility model can play the effect of hinge, under the effect of side blasting of air curtain power, the interior trim top can be crooked along line of weakness, and the flute profile of line of weakness can bend rapidly under external force, and the side gas curtain is discharged easily.Automotive trim top of the present utility model when the collision happens accident, puts in place so that the side gas curtain can discharge from the interior trim top rapidly, reaches the purpose of protection occupant safety.
The line of weakness planform of 2 interior trim tops of the present utility model is simple, compare with V-arrangement or the W connected in star of common employing, trapezoidal groove can prevent effectively that the stress concentration phenomenon from appearring in top, avoids top the fold phenomenon to occur because being subject to external force in installation process; And, be conducive to improve the mold use life-span, under the prerequisite that does not affect result of use, reduced cost.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (5)
