Description
Technical field
The present invention relates to field of automobile safety, and in particular to a kind of automobile-used pedestrains safety protective device.
Background technique
Automotive safety is divided into two broad aspect of active safety and passive security for the vehicle.Active safety is just to try to certainly
Manipulation and control automobile such as.Direction is beaten in braking and acceleration or left and right either on straight line all should be steady as far as possible, be unlikely to
Deviate set travelling route, and does not influence the visual field and the comfort of driver.Such automobile just has relatively high certainly
Accident ability is avoided, still it guarantees automotive safety under conditions of emergency case.Passive security refer to automobile occur accident with
Afterwards to the protection of passenger, the concept of nowadays this protection has been extended to the outer all people of car even object.
According to the patent " pedestrian protection airbag, pedestrian protection inflatable bag device and vehicle " of Publication No. CN206914293U,
Tradition is set to the interior air bag protected to passenger and is arranged to body exterior by the prior art, utilizes gas
The damping, buffering characteristic of capsule reduces the injury caused by pedestrian when vehicle and pedestrian is hit, however relies solely on outside vehicle
The safety that air bag is set to guarantee pedestrian be clearly it is inadequate, vehicle and when pedestrian collision air bag pop-up be possible to further to
Pedestrian distally flicks, and causes secondary injury, or pedestrian is pushed over to cause to roll injury to be involved in vehicle by vehicle.
Summary of the invention
It is caused the technical problems to be solved by the present invention are: providing one kind and can be avoided air bag pop-up to flick pedestrian
The automobile-used pedestrains safety protective device of secondary injury.

Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: 1, when colliding, carry out buffer protection to pedestrian using double-layer air bag,
And it can be avoided pedestrian to be damaged by air bag pop-up；2, grip device can provide the place that can be grasped to pedestrian.
Referring to figs. 1 to Fig. 3, a kind of automobile-used pedestrains safety protective device, including vehicle body 1, airbag apparatus, grip device and open
Close device；
The airbag apparatus includes inner bladder 2, balloon outer 3 and gas generating unit 4, and the inner bladder 2 is arranged
Inside balloon outer 3, the inner bladder 2 and balloon outer 3 are connect by pipeline with gas generating unit 4, described interior
Layer air bag 2 has multiple palates to hang down shape protrusion 201 after inflating, and offers multiple damping holes 301 on the balloon outer 3；
The grip device is rotationally connected with 1 front cover surface of vehicle body；
The switching device includes trigger switch 11 and active switch 12, before the trigger switch 11 is set to vehicle body 1 most
End, the active switch 12 are set to inside vehicle body 1, and the active switch 12 is for keeping driver's active control safe
Protective device is opened, and the switch of active 12 is to be electrically connected with gas generating unit 4, and the trigger switch 11 is filled with gas
4 are set as electrical connection.
The working principle of the invention description: before it will collide, driver can be by pressing active switch 12
Gas generating unit 4 is set to start to generate bulk gas, inner bladder 2 and balloon outer 3, which are inflated, to swell, gas generating unit
4 are lifted grip device by pneumatic line；When collision occurs, pedestrian knocks balloon outer 3, and 3 internal pressure of balloon outer increases
Adding, pedestrian's pop-up, to external leakage, so that balloon outer 3 be avoided to rebound, is caused secondary injury by damping hole 301 by gas,
Balloon outer 3 loses heart after energy-absorbing, and pedestrian can further hit in inner bladder 2, and pedestrian can stick into appointing in inner bladder 2
Two palates of anticipating hang down between shape protrusion 201, further avoid pedestrian and rebounded away by airbag apparatus to cause secondary injury, while pedestrian
The grip device on vehicle body front cover can be caught to keep itself not being ejected；If driver is not timely before colliding
Press active switch 12, then when colliding generation, pedestrian knocks the trigger switch 11 for being set to 1 front end of vehicle body, airbag apparatus and
Grip device is equally able to carry out above-mentioned movement, provides protection for pedestrian.
Seen from the above description, the beneficial effects of the present invention are: no matter while being provided with active switch and trigger switch
In time whether reaction can start pedestrains safety protective device to driver；Balloon outer is provided with damping hole, and can lose heart suction
Can, avoid pedestrian from being flicked；There is the vertical shape protrusion of palate after inner bladder inflation, pedestrian can be blocked, further avoid pedestrian by bullet
It opens；Grip device can allow pedestrian to grasp, and hitting, which facilitates pedestrian when occurring, guarantees that itself is located at the position of vehicles hood,
It avoids being thrown out of and causes secondary injury.
Further, the grip device has multiple, and the grip device includes handle 5, the reset of first piston 6, first
Spring 7, the first cylinder 8, first stroke switch 9 and the first solenoid valve 10, the handle 5 are rotationally connected with 1 front cover surface of vehicle body,
5 middle part of handle is rotatablely connected with first piston 6, and the first piston 6 is slidably connected in the first cylinder 8, and described first
