The tank is connected with a gas bag through a junction valve. In normal situations, the gas bag is rolled in a groove of the front bar.

Description

Automotive anticollision bumper

The utility model relates to the automotive safety parts, especially anticollision bumper of car.

In existing technology, automobile is damaged in order to prevent collision, all is intensity that adopt to strengthen front bumper, and shock absorber is not set, so appearance is the collision phenomenon of confronting the tough with toughnees, makes and is hit thing and automobile self all can be subjected to badly damaged.

The purpose of this utility model is exactly at this deficiency of existing in prior technology, and a kind of anticollision bumper of car technical scheme that possesses the flexible buffer collision is provided.

This programme is realized by following technical measures.At the anticollision bumper of car of mainly being made up of preceding thick stick 1 and connecting panel 5, the characteristics of this programme are that being equipped with at least two between described preceding thick stick 1 and the connecting panel 5 connects springs 6; And thick stick 1 is a rectangular box-like before described, is processed with at least one jar groove 7 and supporting plate 8 in it; At each jar groove 7 and 8 of supporting plates storage tank 4 is housed, the outlet of this storage tank 4 has and connects valve 3, and is that mushroom strip shaped air sac 2 is connected by connecting valve 3 with a cross-sectional plane; Described air bag 2 is in the groove of thick stick 1 before being wrapped under normal condition.In the used storage tank 4 of this programme, to be filled with the unreactable gas of compression.

The anticollision bumper of car that adopts the described technical characterictic of this programme to constitute.Be to utilize its connecting panel that anti-impact bumper is connected with car body.Under normal circumstances, air bag is within the groove of thick stick before being wrapped in, so the same with conventional bumper/spoiler.But occurring being about to collision in emergency circumstances; the driver opens the connection valve of storage tank in braking; a jar interior pressure gas is charged and discharged to air bag rapidly; the effect of this effect and brake system is lowered the speed of a motor vehicle rapidly simultaneously; when collision occurring; because air bag has been filled with gas and has been added with and connects spring and make collision obtain buffering, so just can avoid or reduce and be collided the badly damaged of thing and vehicle self, plays the certain protection effect.This shows, the utility model compared with prior art, its effect is conspicuous.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is that the A-A of Fig. 1 under inflated condition is to cross-sectional schematic.

Now by a specific embodiment and in conjunction with its accompanying drawing, the utility model is described in further detail.Anticollision bumper of car is to have one to be used for and car body bonded assembly connecting panel 5 and preceding thick stick 1, and two connection springs 6 that are used to connect both are housed between preceding thick stick 1 and connecting panel 5.And thick stick 1 is a rectangular box-like before described, is processed with two jar grooves 7 and supporting plate 8 in it; Fill the storage tank 4 of compression nitrogen in two jars of grooves 7 and 8 of supporting plates are equipped with, the outlet of this storage tank 4 is equipped with and is connected valve 3.And connect the conventional quck-opening valve that valve 3 can adopt the quck-opening valve same structure of using with gas fire extinguisher, and to connect a cross-sectional plane be mushroom strip shaped air sac 2 by connecting valve 3.This air bag 2 is in the groove of thick stick 1 before being wrapped in, to have constituted the utility model thus under normal condition.
