Abstract

The utility model discloses a car soft protective device, which comprises a front buffering plate and a rear buffering plate with the shapes matched with the shape of the front part of a car; safe air bags are arranged between the front and rear buffering plates, two ends of the front buffering plate are provided with rolling protective bumpers, and the rear buffering plate is mounted at the front part of the car body by a spring device; each rolling protective bumper is formed by a rolling shaft and an external protective bumper sleeved on the rolling shaft, each protective bumper rolls relative to the related rolling shaft, and the rolling protective bumpers are mounted at the corners at the front part of the car; and a distance sensor is arranged in the front of the front buffering plate. The car soft protective device has the dual arrangements of the air bag and the spring, which are capable of interacting, thus achieving better buffering effect; and the rolling protective bumper at two ends of the car head is used for reducing the friction between the car body and a collided object, thus effectively protecting the personal safety of pedestrians, better protecting the car body and preventing the scratching of the car body to further lower the damage.

Description

The automobile flexible protection

Technical field

The utility model relates to a kind of car protective device, belongs to the vehicular spare parts technical field.

Background technology

Present automotive front all can the erection insurance thick stick; the bumper/spoiler of prior art all is to adopt rigid protections such as steel plate or plastic flagstone, and this bumper/spoiler is when bumping, and moment can produce bigger impulsive force; be unfavorable for protecting vehicle body and pedestrian, especially can damage the pedestrian.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of can the better protection car body and the car protective device of pedestrains safety.

For solving this technical matters; the utility model provides a kind of automobile flexible protection; comprise the front buffer plate and the back dash plate that coincide with the Vehicular body front shape; between front buffer plate and back dash plate, be provided with safety air bag; the two ends of front buffer plate are provided with the protection thick stick that rolls, and back dash plate is installed in the front portion of car body by spring installation.

Described rolling protection thick stick by the axis of rolling, and outside protection thick stick forms, the protection thick stick is enclosed within on the axis of rolling, the protection thick stick rolls relatively with respect to the axis of rolling, rolls and protects thick stick to be installed in the corner in car body the place ahead.

The place ahead at front buffer plate is provided with rang sensor.

Beneficial effect: the utility model has safety air bag and the dual setting of spring; mutual action; thereby reached better buffering effect; the rolling protection thick stick at headstock two ends; be used for reducing vehicle body and the friction of colliding thing; can protect pedestrian's personal safety effectively, also can well prevent scratch for the protection vehicle body simultaneously, will damage further and reduce.

Description of drawings

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

Fig. 2 is the structural representation of rolling protection thick stick of the present utility model.

Among the figure: 1 front buffer plate, 2 back dash plates, 3 safety air bags, 4 spring installations, 5 rolling guard bars, 6 rang sensors, 7 car bodies.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is done specific descriptions.

Figure 1 shows that structural representation of the present utility model.

The utility model comprises front buffer plate 1 and back dash plate 2, and the shape of front buffer plate 1 and back dash plate 2 and the front shape of car body 7 are coincide.

Between front buffer plate 1 and back dash plate 2, be provided with safety air bag 3.

Back dash plate 2 is installed in the front portion of car body 7 by spring installation 4, and the spring installation 4 between back dash plate 2 and the car body 7 can cover with flexible metal conduit, to reach effect attractive in appearance.

The both sides of front buffer plate 1 are provided with the protection thick stick 5 that rolls.

Figure 2 shows that the structural representation of rolling protection thick stick of the present utility model.

Described rolling protection thick stick 5 by the axis of rolling, and outside protection thick stick forms, the protection thick stick is enclosed within on the axis of rolling, the protection thick stick rolls relatively with respect to the axis of rolling, rolls and protects thick stick 5 to be installed in the corner in car body 7 the place aheads.

The protection thick stick 5 that rolls not only can be installed in the front portion of car body 7, at the rear portion of four jiaos of car body 7, vehicle body side and car body 7 this rollings can be installed all and protect thick stick 5.

The place ahead at car body 7 head front buffer plates 1 is provided with rang sensor 6, in order to the distance between sense vehicle and the obstacle, set a distance value, such as: 3cm---10cm, when reaching this distance value between automobile and the obstacle, rang sensor 6 passes to ignition device rapidly with signal, thereby makes before automobile and the real collision of obstacle, and safety air bag 3 is inflation.

Principle of work of the present utility model: under the normal condition, front buffer plate 1 fastens with back dash plate 2 and is one, and safety air bag 3 is shrivelled shape, is clipped between front buffer plate 1 and the back dash plate 2; In the moment that bump takes place, the inductor in the safety air bag 3 is measured acceleration/accel, and when acceleration/accel arrived certain value greatly, microprocessor sent ignition signal, lighted azide, makes it blast generation gas and pours air bag; Within this a few tens of milliseconds, air bag is not opened as yet fully, bump will cause spring to receive compression, thereby avoided hard collision, then, under the elastic restoring force effect along with the rapid expansion of air bag and spring, automobile kinetic energy reduces rapidly, be converted into elastic potential energy, interiorly can or simply automobile be pushed away the collision thing, thus the buffering of playing, the effect of damping.

If automobile and the non-head-on crash of obstacle, but deflection friction, the bumper/spoiler that then rolls is rolled by friction force, avoids rigid friction, thereby further reduces infringement.

The safety air bag that the utility model will protect the driver to use is used for vehicle body; has the dual setting of safety air bag and spring; mutual action; thereby reached better buffering effect; the rolling protection thick stick at headstock two ends is used for reducing vehicle body and the friction of colliding thing, can protect pedestrian's personal safety effectively; also can well prevent scratch for vehicle body simultaneously, will damage further and reduce.

The above-mentioned embodiment of the utility model, just casehistory is not only, all in the utility model scope or the change that is equal in the scope of the present utility model all surrounded by the utility model.
