Fig. 4 is a blast structural representation of the present utility model.
In Fig. 1-4,1: the hinge upper bracket; 2: bearing pin; 3: steel back lining; 4: the first hinge page or leaf plates; 5: the second hinge page or leaf plates; 6: the hinge lower carriage; 7: the three hinge page or leaf plates; 8: spring; 9: the first limited blocks; 10: the second limited blocks.
The specific embodiment
By the combination of structure shown in Fig. 1-4 as can be known, this kind automotive hood comprises hinge upper bracket 1 with hinge, one end of hinge upper bracket 1 is connected with an end of the first hinge page or leaf plate 4 and an end of the second hinge page or leaf plate 5 with steel back lining 3 by bearing pin 2, the other end of the first hinge page or leaf plate 4 is connected with hinge lower carriage 6 with steel back lining 3 by bearing pin 2, the other end of the second hinge page or leaf plate 5 is connected with the end of steel back lining 3 with the 3rd hinge page or leaf plate 7 by bearing pin 2, and the other end of the 3rd hinge page or leaf plate 7 is connected with hinge lower carriage 6 by bearing pin 2, steel back lining 3 and spring 8.
Be provided with first limited block 9 that restriction the 3rd hinge page or leaf plate 7 rotatablely moves with respect to hinge lower carriage 6 with the 3rd hinge page or leaf plate 7 junctions on the hinge lower carriage 6; Be provided with second limited block 10 that the restriction second hinge page or leaf plate 5 rotatablely moves with respect to the 3rd hinge page or leaf plate 7 with the second hinge page or leaf plate, 5 junctions on the 3rd hinge page or leaf plate 7.
Bearing pin 2 has five, is riveted on respectively on hinge upper bracket 1, hinge lower carriage 6 and the 3rd hinge page or leaf plate 7; Steel back lining 3 has five, is separately fixed on the first hinge page or leaf plate 4, the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7, and each steel back lining 3 rotates with respect to the bearing pin corresponding with it 2; Two joints of spring 8 are separately fixed on hinge lower carriage 6, the 3rd hinge page or leaf plate 7 by the hook of bending or in the mode of welding respectively.
Hinge lower carriage 6 is a kind of installing plates that connect vehicle body, two joints of spring 8 wait other modes to be separately fixed on hinge lower carriage 6 and the 3rd hinge page or leaf plate 7 by crooked hook or welding, and hinge lower carriage 6 and the 3rd hinge page or leaf plate 7 have just produced the elastic potential energy of spring 8 when rotating mutually around bearing pin 2.Spring 8 also can be arranged on other positions or the bearing pin 2, also can use the spring 8 of different structure, but the principle of produce power conversion is with described herein.
The first hinge page or leaf plate 4, the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7 all can be around the axial line rotations of bearing pin 2.The 3rd hinge page or leaf plate 7 is a kind of commentaries on classics moveable leaf plates under stressing conditions, be subjected to certain car load-Z under the effect of power at hinge, the 3rd hinge page or leaf plate 7 can be around the axial line rotation of the bearing pin on the hinge lower carriage 62, spring 8 can be subjected to certain moment of torsion and produce distortion, absorbs the elastic potential energy that part energy changes into spring 8.
We can realize the technology that provides by the utility model: 1, under the effect of hood opening force, hood by hinge the first hinge page or leaf plate 4 and the second hinge page or leaf plate 5 according to certain track with respect to body movement, satisfy the requirement that hood is opened; When 2, the positive bump being taken place between pedestrian and motor vehicle, when pedestrian head impinged upon hood hinge and phase near field, the 3rd hinge page or leaf plate 7 rotated and collision energy is changed into the elastic potential energy of spring 8 around the bearing pin on the hinge lower carriage 62.Hood is the negative direction motion of the first hinge page or leaf plate 4 by hinge and the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7 towards car load Z axles also, and the impact acceleration of pedestrian head is played certain cushioning effect, has reduced the injury values to pedestrian head.
This kind automotive hood is fixed the counterrotating kinematic pair of the 3rd hinge page or leaf plate 7 and hinge lower carriage 6 by a spring 8 with hinge, and the potential energy of its energy that rotates mutually and spring 8 can be changed mutually.Hinge upper bracket 1 and hood are fastening by bolt or other modes, and hinge lower carriage 6 and vehicle body are fastening by bolt or other modes.By adjusting the length and the relative position of riveting of the first hinge page or leaf plate 4, the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7, can adjust different hood movement locus.This hinge is left part, and hood can be installed a plurality of this kind hinges, and other hinges are identical with it or symmetrical, thereby satisfies the unlatching requirement of hood.
When normal unlatching hood, first limited block, 9 restrictions the 3rd hinge page or leaf plate 7 rotatablely moves with respect to hinge lower carriage 6, and hinge is done the motion of four connecting rods, produces a pre-designed movement locus; When normally killing engine cover, the initial prefastening torque power of spring 8 limits the 3rd hinge page or leaf plate 7 rotatablely moving with respect to hinge lower carriage 6, hinge is done the motion of four connecting rods, produces a pre-designed movement locus, thereby satisfies the unlatching requirement of hood.
In when, between pedestrian and the motor vehicle positive bump taking place when, when pedestrian head impinges upon hood hinge and phase near field, hinge has produced the negative Z of a car load to movement tendency, this moment, the 3rd hinge page or leaf plate 7 can rotate with respect to hinge lower carriage 6, the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7 negative Z to motion the time since second limited block 10 close stopping means existence and can not relative rotary motion, thereby make the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7 form a new relatively-stationary connecting rod, with hinge upper bracket 1, the hinge lower carriage 6 and the first hinge page or leaf plate 4 have formed four new link motion pairs.This kind structure also can be cancelled second limited block 10, and this moment, hinge was a kind of five bar linkage structures of being made up of hinge upper bracket 1, hinge lower carriage 6, the first hinge page or leaf plate 4, the second hinge page or leaf plate 5 and the 3rd hinge page or leaf plate 7.Hood along with the four-bar linkage structure hinge of new formation or five bar linkage structure hinges according to the trajectory generation of new formation negative Z to motion, and when the 3rd hinge page or leaf plate 7 rotatablely moves around the bearing pin on the hinge lower carriage 62, collision energy changes into the elastic potential energy of spring 8, thereby the impact acceleration to pedestrian head plays certain cushioning effect, has reduced the injury values to pedestrian head.
After collision finishes,, hinge need more renew hinge if producing destructions such as distortion, fracture.
