Abstract

The utility model relates to a side collision car door invasion limiting structure of a sports car, which comprises a car door internal plate and a side wall external plate including a side wall B column and a threshold, wherein the joint of the car door internal plate and the side wall external plate is provided with a side collision car door invasion limiting bracket which is shaped as a groove, one side of the side collision car door invasion limiting bracket is connected with the car door internal plate, and the other side of the side collision car door invasion limiting bracket is matched with a positioning hole arranged at the edge of the side wall external plate. The utility model solves the problems that the door car directly invades the passenger bin so as to seriously threaten the safety of the passenger when in side collision because the size of the prior car door is larger and the overlap amount of the prior car door and the passenger body is bigger.

Description

A kind of sports car side collision car door is invaded limiting structure

Technical field

The utility model relates to a kind of sports car side collision car door and invades limiting structure.

Background technology

In order to occupy the domestic and international market, each main engine plants more and more payes attention to the side face collision safety of vehicle newly developed.Simultaneously, the safety problem of automobile also more and more is subjected to customer's attention, and for the safety of automobile, body structure is the most basic, most important.Conventional car door and gusset are to amount to three connections that are rigidly connected by two hinges and a snap close, and Joint strenght is limited, and as shown in Figure 1, therefore with respect to four general three box cars, there are following two problems in the new model of two hatchback sport cars:

1. the car door size is bigger, and is bigger with occupant's trunk lap, and the size of car door intrusion amount played a crucial role to occupant's safety when side collision took place;

2. the overlapping scope of car door and gusset is less during side impact, and car door directly slips over threshold when causing collision to take place, and causes car door intrusion amount bigger, serious threat member safety.

The utility model content

Technical problem to be solved in the utility model is: the sports car side collision car door that at the problem of above-mentioned existence, provide a kind of safety factor height, strengthen carriage body construction, living space is big is invaded limiting structure.

The utility model is achieved in that

A kind of sports car side collision car door is invaded limiting structure, comprise inner plate of car door and the side-wall outer-plate that contains gusset B post, threshold, the junction of described inner plate of car door and described side-wall outer-plate is provided with the side impact car door and invades limit bracket, it is the groove shape that described side impact car door is invaded limit bracket, it links to each other with described inner plate of car door on one side, and the set knock hole in another side and described side-wall outer-plate edge is complementary.

The joint face that described side impact car door is invaded limit bracket and described inner plate of car door is provided with the support brace panel.

Set knock hole place, described side-wall outer-plate edge is provided with the gusset brace panel.

Be provided with sealing shroud in the set knock hole in described side-wall outer-plate edge.

The beneficial effects of the utility model:

The utility model can increase by two point of connection at car door and threshold place, as shown in Figure 2, or at car door and gusset B post place increase point of connection, adds that existing three are rigidly connected a little, amounts to five and is rigidly connected a little, improves the side impact safety of this sports car.When the sports car side runs into collision, side impact car door intrusion limit bracket on the inner plate of car door and the threshold on the side-wall outer-plate or gusset B post can form and be rigidly connected, car door was directly invaded the crew module when energy actv. stoped side impact, improved member's living space, improved the chances of survival of the occupant in the car.In addition, because less to the change of existing structure, just can reach requirement by repairing a die, cost has been saved in by a relatively large margin raising safety under the situation of less change.

Further describe the utility model below in conjunction with accompanying drawing.

Among the figure: 1. door skin; 2. side-wall outer-plate; 3. inner plate of car door; 4. gusset B post; 5. the side impact car door is invaded limit bracket;

6. support brace panel; 7. gusset brace panel; 8. threshold; 9. knock hole.

The specific embodiment

According to Fig. 3, Fig. 4 and Fig. 5, a kind of sports car side collision of the utility model car door is invaded limiting structure, comprise and contain door skin 1, be fixed on the sports car side door that side impact car door on the inner plate of car door 3 is invaded limit bracket 5 and support brace panel 6, and gusset B post 4, threshold 8 and be fixed on the gusset brace panel 7 on the knock hole 9 in the threshold 8.The position of knock hole 9 and side impact car door are invaded limit bracket 5 and are complementary, and as shown in Figure 7, are furnished with rubber sealing boot in the knock hole 9.The bottom that the side impact car door is invaded limit bracket 5 is provided with reinforced rib, as shown in Figure 6.

By side collision power transmission figure shown in Figure 4 as can be seen, when vehicle body was subjected to side collision, the lap of car door and gusset was less, car door can directly slip over threshold when collision took place, can not absorb energy by actv., cause car door intrusion amount excessive, the serious threat occupant safety.And having increased by two places between car door and threshold, structure of the present utility model is rigidly connected, significantly increased the Joint strenght between car door and the gusset, strengthen the vehicle body integral rigidity, car door directly slips over threshold when stoping side collision, reduce car door intrusion amount to greatest extent, guarantee passenger's the interior living space of car, improve occupant safety.Below the mechanism of action of the present utility model is analyzed:

Analysis chart 3, Fig. 4 and the force diagram of body structure shown in Figure 5 when side impact, as can be seen, car door and threshold lap-joint owing to the effect of extraneous impact force be subjected to Y to the effect of Z to power, side collision when taking place in the body structure of prior art because threshold is less with the car door overlapping region, threshold to car door Z to Y to the equal deficiency of the limitation capability of distortion, can cause car door directly to slip over threshold, invade the crew module, the aggravation occupant injury reduces occupant's chances of survival.And used body structure of the present utility model when side collision takes place, under the effect of extraneous impact force, side collision door is invaded a limit bracket and can be snapped in the threshold, make car door and threshold form local being rigidly connected, when side impact takes place, can effectively resist Y that car door is subjected to Z to power, avoid car door directly to slip over threshold, reduce car door invasion amount, reduce occupant injury, improve occupant's chances of survival.Therefore, the utility model can better meet the requirement of collision rules, improves the side impact safety performance of described sports car.
