Description

A kind of safety device that is used for self-propelled vehicle
Technical field
The utility model relates to self-propelled vehicle, more particularly, relates to a kind of being installed on the self-propelled vehicle, is used to slow down the safety device of impact.
Background technology
Along with the increase and the speed of a motor vehicle of self-propelled vehicle are accelerated, traffic accident is also increasing.In order to reduce traffic accident, especially in order to reduce the bump injury of self-propelled vehicle to human body, people have invented the multiple anticollision device that is used for self-propelled vehicle.As, anticollision device such as rubber pneumatic bag is installed on the safety lever of self-propelled vehicle is absorbed and reduce impact energy.And for example, car bonnet is made the structure that can up lift, when car and pedestrian impact, car bonnet pops up several inches automatically, can form flexible folding Zou to pedestrian head and be with and protect.Though existing several anticollision devices can reduce the impact to pedestrian head and shoulder, and prevent the pedestrian from hitting the bottom section of Windshield and the injury that causes.But, lift several inches on only during car bonnet contact pedestrian, motion amplitude is less, the impact kinetic energy that very difficult counteracting is bigger.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of safety device that is used for self-propelled vehicle, and it can dissolve bigger impact kinetic energy when self-propelled vehicle strikes the pedestrian.
The purpose of this utility model is achieved in that a kind of safety device that is used for self-propelled vehicle, there is car bonnet in self-propelled vehicle the place ahead, and the top of car bonnet is provided with slip lid, and slip lid is structure slidably, the sliding stroke of slip lid has 20 centimetres at least, and slip lid slides control mechanism.
On the basis of technique scheme, the utility model also has following further scheme:
The described control mechanism that slides is an ejection mechanism, and ejection mechanism has crash sensor.
Described crash sensor is in conjunction with speed sensor.
On the moving line of described slip lid or slip lid block is arranged, blocking is collapsible structure, and block connects the block ejection mechanism, and the block ejection mechanism launches master cock.
There is the rubber pull bar described block both sides, and block connects the block ejection mechanism by the rubber pull bar.
Described slip lid constitutes slidably structure by track, and track extends toward the self-propelled vehicle top.
Between described slip lid and the track pulley is arranged, pulley connects slip lid by horizontal slide mechanism.
Advantage of the present utility model is as follows:
Generally, self-propelled vehicle bumps against the pedestrian and not during stop motion, is bumped with the Windshield of self-propelled vehicle after hitting the pedestrian and often being poured on the car bonnet again.Owing to above the starting motor-driven vehicle hood slip lid is set, slip lid is structure slidably, and the sliding stroke of slip lid has 20 centimetres at least, and slip lid slides control mechanism.Hit and to be moved backward with slip lid after the pedestrian contacts slip lid, when slip lid is mobile backward, not only can absorb and shift the part impact kinetic energy, and can also prevent that being hit the pedestrian contacts Windshield.
