The phenomenon that loosening deflection is generated in the rotary course of moving axis 5.
In the present embodiment, entire limit hinge is integrated with the effect of conventional hinge and pneumatic rod, by hinge bodies 2 and limit
The integration of position mechanism 4, weight is only 0.162kg, compared with the existing technology in both conventional hinge and pneumatic rod weight and
For 1.093kg, loss of weight 0.931kg, weight-loss ratio reaches 85%；The material that each component is selected can be aluminum alloy material, such as
The aluminium alloy that row number is 6061, compared with the existing linkage using Steel material, weight can reduce 30% again.In the present embodiment
Limit hinge can be on the back door or luggage-boot lid of small-sized, light-duty electric car, if by the present embodiment
Limit hinge is applied on new-energy automobile, and critically important effect will be played in terms of the lightweight of vehicle body.
Incorporated by reference to shown in Fig. 3-4, the course of work of limit hinge in the present embodiment are as follows: when automotive back door unlock, after
After the lock being arranged in tailgate is opened, flexible drive mechanism 3 can drive hinge bodies 2 around pedestal during restoring deformation
The rotation axis 5 worn on 1 rotates in the direction of the clock, and rotation axis 5 then drives position-limit mechanism 4 also to rotate in a clockwise direction,
Since the internal messing of first gear 41 and second gear 42 acts in position-limit mechanism 4, resistance is produced to the rotation of hinge bodies 2
Effect, so that the rotation speed of hinge bodies 2 is more gentle, meanwhile, hinge bodies 2 can rotate in default range, energy
Back door is set to automatically turn on certain degree with gentle speed；Likewise, being arranged on back door when automotive back door locking
Lock close after, flexible drive mechanism 3 is acted on the rotation that hinge bodies 2 can be driven to wear on pedestal 1 by external force
Axis 5 is rotated with direction counterclockwise, and rotation axis 5 then drives position-limit mechanism 4 to rotate with direction counterclockwise, due to position-limit mechanism
The internal messing of first gear 41 and second gear 42 acts in 4, produces drag effect to the rotation of hinge bodies 2, so that hinge
The rotation speed of chain ontology 2 is more gentle, meanwhile, hinge bodies 2 can rotate in default range, and back door can be made with flat
Slow speed is automatically closed.
It is above-mentioned obviously it can be concluded that, the limit hinge provided in the present embodiment, by the way that flexible drive mechanism is connected to hinge
On chain ontology, so that the driving hinge bodies rotation when automobile back door assembly unlocks or is latched of flexible drive mechanism, and pass through limit
Rotation displacement of the mechanism limitation hinge bodies in position relative to pedestal, to effectively control the opening degree of automobile back door assembly；
Especially, by adding flexible drive mechanism between pedestal and hinge bodies, the deformation that can use flexible drive mechanism is extensive
Reactivation power realizes the automatic opening and closing of tailgate assembly.Meanwhile selecting torsionspring as flexible drive mechanism, it reduces
The manufacturing cost of limit hinge.Further, aluminum alloy materials are selected to make each component, the lightweight for being conducive to vehicle body is set
Meter.
The utility model embodiment also proposed a kind of automobile, which includes the limit hinge in above-described embodiment.
It is well-known to those skilled in the art to be, two limit hinges can be installed in the interface two sides that automobile top cover is connect with tailgate assembly
Chain is to realize the open and close of tailgate assembly.
Since limit hinge has said effect, so also there is the automobile with the limit hinge corresponding technology to imitate
Fruit.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
