Description
Technical field
The utility model belongs to field of automobile, is specially set to a kind of pedestrian protecting conquassation hinge of cover
Chain.
Background technology
With the rapid development of Domestic Automotive Industry, car ownership is continuously increased, traffic accident rate and dead
It dies rate to occupy first place in the world for years, for the more preferable suitable real development for answering automotive engineering, reinforces the guarantor to the equal disadvantaged group of pedestrian
Shield, our countries will also implement pedestrian protecting regulation in 2018, the implementation of the pedestrian protecting regulation band for Automobile Enterprises
Come new challenge, active safety and the Main way for being passively mounted for the promotion of future automobile pedestrian protecting, be crushed hinge as
The direction of improvement of cover pedestrian protecting, is increasingly paid attention to by everybody.And common Four-connecting-rod hinge structure, it can only realize positive machine
The unlatching of lid, it can not achieve the collapse energy-absorption after cover collision.
Invention content
The purpose of this utility model is to provide one kind to play the role of protecting crusherbull zone pressure after cover collision
Routed hinge.The purpose of this utility model is achieved through the following technical solutions.
A kind of pedestrian protecting conquassation hinge, includes the hinge seat of the hinge arms of upper end and lower end, the hinge arms and hinge
Be provided with first connecting rod, second connecting rod and third connecting rod between seat, the both ends of the first connecting rod respectively with hinge arms and hinge
Seat is hinged；Third connecting rod one end is hinged with hinge arms, and the other end connects second connecting rod, and second connecting rod is hinged with third connecting rod, and
Junction setting limit square cotter；The other end of second connecting rod is hinged with hinge seat；Second connecting rod upper end, positioned at limit square cotter it is upper
Side's setting caging bolt, the upper surface of caging bolt is located at the lower section of hinge arms lower face.
Further, being sequentially connected by upper surface, side end face and lower face for hinge arms is constituted, upper surface setting for
Cover connection through-hole, side end face setting there are two through-hole and by hinge axis, bushing respectively with first connecting rod and third connecting rod
It is hinged.
Further, there are one vertical with connecting rod side with the setting of the top of the connecting pin of third connecting rod in second connecting rod
Plane is protruded, the through-hole being provided in plane for connecting caging bolt is protruded.
Further, hinge seat setting connects with first connecting rod and second respectively there are two through-hole and by hinge axis, bushing
Bar is hinged.
Further, corresponding through-hole is arranged in the junction of the second connecting rod and third connecting rod, by limit square cotter and
Hinge axis is connected with bushing across through-hole.
Further, the limit square cotter is irony.
The beneficial effects of the utility model：
The cover hinge realizes the opening and closing work(of cover as common Four-connecting-rod hinge function in normal use
After energy, vehicle or cover collide, the connecting rod cracking connected by square cotter, entire mechanism becomes five-bar mechanism, and cover touches
The collapse energy-absorption for hitting rear end sinks.
The utility model is described in detail with reference to the accompanying drawings and examples.

Specific implementation mode
As shown in Fig. 1 ~ 3, a kind of pedestrian protecting conquassation hinge includes the hinge seat 1 of the hinge arms 5 of upper end and lower end, cuts with scissors
First connecting rod 2, second connecting rod 3 and third connecting rod 4, the both ends point of the first connecting rod 1 are provided between chain arm 5 and hinge seat 1
It is not hinged with hinge arms 5 and hinge seat 1；4 one end of third connecting rod is hinged with hinge arms 5, other end connection second connecting rod 3, and second
Connecting rod 3 is hinged with third connecting rod 4, and junction setting limit square cotter 9, one end of second connecting rod 3 and hinge seat 1 are hinged；Second
Caging bolt 8 is arranged positioned at the top of limit square cotter in small end, and the upper surface of caging bolt 8 is located at 5 lower face of hinge arms
Lower section.
Being sequentially connected by upper surface, side end face and lower face for hinge arms 5 is constituted, and upper surface is arranged for being connect with cover
Through-hole, side end face setting there are two through-hole, it is hinged with first connecting rod 2 and third connecting rod 4 respectively by hinge axis 6, bushing 7.
There are one the protrusions vertical with connecting rod side to put down with the setting of the top of the connecting pin of third connecting rod 4 in second connecting rod 3
The through-hole being provided in plane for connecting caging bolt 8 is protruded in face.
The setting of hinge seat 1 is cut with scissors with first connecting rod 2 and second connecting rod 3 respectively there are two through-hole and by hinge axis 6, bushing 7
It connects.
Corresponding through-hole is arranged in the junction of second connecting rod 3 and third connecting rod 4, passes through 9 He of limit square cotter of front end
Rear end setting hinge axis 6 is connected with bushing 7 across through-hole.
Double leval jib becomes five bar hinge mechanisms after the utility model improves, and wherein second connecting rod and third connecting rod passes through hinge
Chain rivet is connected with limit square cotter, and before square cotter is not crushed by collision, entire hinge is still four-bar linkage structure, can only be realized just
Unlatching to cover, the collapse energy-absorption of rear end sinks after cover collision.
