Abstract
The utility model discloses a kind of lifting device of engine cover for vehicle, including sleeve, and the bottom of the sleeve is fixed with thrust generator, and the top of the sleeve is equipped with the cover；The inside of the sleeve is provided along its length mandril, and one end of institute's mandril is connected to thrust generator by piston, and the other end of the mandril is equipped with mandril cap, and the mandril cap is in contact with the cover.A little quick-fried, cooperation pedestrian protecting hinge can be carried out by generator when vehicle collides, generator orientation ejection pushes hinge to make bonnet lifting requirement height, to achieve the purpose that protect pedestrian.
Description
Technical field
The utility model belongs to vehicle passive safety field, and the lifting more particularly to a kind of engine cover for vehicle fills
It sets.
Background technique
In general, vehicle, which has, is arranged fore engine room, wherein engine room is opened or closed by hood.
Hood is a kind of suitable for being started by covering engine room and cutting off engine noise and open or close
The component of machine room, wherein the left and right side of the rear end of usual hood is connected to the upper of engine room by hinge assembly
Portion, so that hood can be rotated around hinge assembly to open or close engine room.
It is well known, however, that such hood is a kind of portion to cause serious injury when pedestrian impact occurs to pedestrian
Part.Thus, Active hood system is applied to such hood recently, so that in pedestrian's collision accident, energy
Enough spaces for guaranteeing to absorb pedestrian impact energy between hood and engine room.
Active hood system is a kind of for rising hood to protect row when pedestrian impact occurs
The system of people, and can reduce pedestrian injuries' index as one kind in pedestrian's collision accident and absorb the impact of pedestrian
Pedestrian protecting safety device.
In conventional Active hood system, if being mounted on front bumper when pedestrian impact is to front bumper
On sensor sense pedestrian impact, then controller according to the sensing signal of sensor operate actuator so that hood
Rear end rise, make it possible to ensure impact absorbing space between hood and engine room.
At this point, actuator is in quilt if controller receives the sensing signal from sensor and drives actuator
The rear end for the hood for rising hinge assembly when driving, while connecting hinge assembly is risen, to push up row
People is to absorb the impact of pedestrian.
The utility model develops one on the basis of utilizing the spiral type thrust generator in patent CN101576021
The lifting device of kind engine cover for vehicle.
Utility model content
The utility model is to solve technical problem present in above-mentioned background technique, provides a kind of engine cover for vehicle
Lifting device.
The utility model is realized using following technical scheme: a kind of lifting device of engine cover for vehicle, including set
Cylinder, is fixed on the thrust generator of the sleeve bottom, the cover at the top of sleeve is arranged in, be socketed in sleeve inner and along sleeve
The mandril that length direction extends, the piston being connected between mandril one end and thrust generator, and it is fixed on the mandril other end
And the mandril cap abutted with the cover.
Further, the mandril offers venthole close to one end of thrust generator.
Further, the outer surface of the piston is fixed with sealing ring.
Further, the end of the sleeve is welded with ring flange, and the cover is fixed on ring flange by lock bolt
On.
Further, it is fixed between the mandril cap and mandril by rivet.
Further, it is fixed between the thrust generator and the sleeve by rivet.
Further, the sealing ring is O-ring seal.
The utility model has the beneficial effects that a little quick-fried, cooperation pedestrian protecting can be carried out by generator when vehicle collides
Hinge, generator orientation ejection pushes hinge that bonnet lifting is made to require height, to achieve the purpose that protect pedestrian.

Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of lifting device of engine cover for vehicle,
Including sleeve, the bottom of the sleeve is fixed with thrust generator, and the top of the sleeve is equipped with the cover；The inside of the sleeve
It is provided along its length mandril, one end of institute's mandril is connected to thrust generator by piston, and the other end of the mandril is set
Have mandril cap, the mandril cap is in contact with the cover, can relative sleeve generate sliding, the mandril close to thrust occur
One end of device offers aperture, to be exhausted.
The outer surface of the piston is uniformly fixed with O-ring seal.
The cover is fixed on ring flange by lock bolt, passes through assemble welding at the top of the ring flange and sleeve
It is fixed.It is assembled and is fixed by rivet between the mandril cap and mandril.It is filled between the generator and the sleeve by rivet
With fixation.
At work, thrust generator generates force of the breath to entire dynamical system, by pushing piston to make mandril in regulation
Interior ejection height H, as shown in figure 4, to meet system requirements.
For those skilled in the art, it is possible to understand that in the situation for not departing from the principles of the present invention and spirit
