Description of the drawings
Fig. 1 shows the active pedestrian protecting hinge for engine hood of twin axle of the present invention；
Fig. 2 shows the back sides of the active pedestrian protecting hinge for engine hood of twin axle shown in FIG. 1；
Fig. 3 shows the open state of the active pedestrian protecting hinge for engine hood of twin axle of the present invention.
Specific implementation mode
Hereinafter, being carried out specifically to the active pedestrian protecting hinge for engine hood of the twin axle of the present invention in conjunction with attached drawing
It is bright.The prompting vehicle travel direction in figure is marked with arrow FR.
The automobile engine cover hinge of twin axle active pedestrian protecting include upper piece（Support chip）3 and bottom sheet 1, upper and lower piece
It is connected by axis pin 2, bottom sheet 1 is fixed on body structure.Under normal use, similar to single axle hinge for engine hood.
To realize active pedestrian protecting function, in hinge upper piece（Support chip）3 design cross-compound arrangement protecgulum upspring structures.
Bounce piece 6 and upper piece（Support chip）3 are connected by axis pin 7, and wherein hood is fixed on by specific connection type and bounces piece 6
On.When trigger active pedestrian protecting, upper piece（Support chip）3 remain stationary as, and bounce piece 6 and lift certain height around the rotation of axis pin 7
Degree ensures that hood lower part has a space when pedestrian impact.
It is to realize the primary structure of actively protection to bounce piece 6, includes the flange of support hood.Slider 10 being capable of phase
For upper piece（Support chip）3 slidings.Elastic device 4 is constructed so that bounce piece 6 rotates around 7 hinge of axis pin, while making sliding
Piece 10 slides.
In one embodiment, elastic device is configured to torque spring, one end against slider 10 card slot 13, it is another
One end is against the lower surface for the flange for bouncing piece 6.
Position-limit mechanism 12 is fixed on piece（Support chip）On 3, when pedestrian impact, position-limit mechanism 12 is activated, and starts row
People protects, and sees Fig. 3.Position-limit mechanism 12 is designed with resetting-mechanism, can reuse.The position-limit mechanism 12 includes but not limited to electricity
Magnet valve structure.
When solenoid valve is not activated, bolt-type locking member is in extended position, is contained in the recess of slider 10,
To limit the release of torque spring, torque spring is in precompressed state at this time, and elastic potential is provided to promote hood
Energy.When solenoid valve is activated, bolt-type locking member is retracted, and limit is cancelled, to discharge torque spring.In torque spring
Under the action of, it bounces piece 6 and is rotated around 7 hinge of axis pin, slider 10 is relative to upper piece（Support chip）3 slidings, torque spring is by bullet
Playing piece 6 and slider 10 strut certain angle, to promote the hood.
It includes the arm equipped with conduit to bounce piece 6, which accommodates piece（Support chip）3 the first guiding pin 8, for guiding
The hinge that piece 6 is bounced around axis pin 7 rotates.The conduit can also limit bounce piece 6 lift angle.Elastic element 9 is in collision bullet
It rises close to being provided when extreme higher position and buffers and limit.
Slider 10 includes being equipped with guide groove, and guide groove accommodates piece（Support chip）3 the second guiding pin 11, for guiding sliding
Piece 10 is relative to upper piece（Support chip）3 sliding.Slider moves to position shown in Fig. 3 along the track of guide groove.
In collision process, solenoid valve receives the signal of crash sensor transmission, retraction bolt-type locking member, torsion bullet
Spring pushes slider 10 to be rotated around the second guiding pin 11, lid side installation sheet and protecgulum is lifted, in this way, increasing under hood
Portion space reduces pedestrian head injury values.
After collision triggers, crash sensor power-off, the release of bolt-type locking member can be by pressing hood two
Side hinge is caught in again in the recess of slider 10, and so it can be used repeatedly, reduces the maintenance cost for replacing hinge.
The present invention a kind of active pedestrian protecting of twin shaft hinge for engine hood, compared to relatively at present main five shaft type and
The pedestrian protecting hinge of multishaft gear rack-and-pinion labyrinth has following advantage：Structure design advantages of simple, reliability is high, durable
Property it is good, can repeatedly use, performance is stablized, and manufacturing process is simple, light-weight, installation and easy to operate etc..
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is used, or without changing
Other occasions are directly applied to by the design of the present invention and technical solution, within protection scope of the present invention.
