Description
Technical field
The present invention relates to automobile safety system field, cover hinge before specifically a kind of active upspring type.
Background technology
The fast development of auto industry and science and technology causes automobile to have become as traffic work essential in people's daily life
Tool.With the continuous improvement of car ownership, traffic accident also more frequently, thus the safety of automobile more and more by
The attention of people.
The survey showed that：More than 50% is bumped against with car in the collision process of pedestrian and vehicle, and in traffic accident
The rate that has occurred of head impact injury is up to 54%.After pedestrian and front part of vehicle collide, most accidents are pedestrian and vapour
Colliding again with hood after vehicle collision causes head severely injured or even fatal.Conventional hinge is empty due to not enough deformations
Between and there are hard spots in hinge for engine hood region, easily pedestrian head is damaged when pedestrian collides with vehicle.
In the prior art, at present, cover hinge is to be realized by a rotating mechanism in vehicle before active upspring type in the market
During collision, front engine cover of car end is lifted certain altitude, reaches pedestrian protecting function, using the above method, be primarily present with
Lower shortcoming：1st, product structure is complicated, number of fitting parts is more, weight weight；2nd, assembling product complex process, assembling procedure are more；3rd, product
Using with limitation：It is required that two mounting surfaces directions of hood hinge must be consistent.
Invention content
Goal of the invention：It is an object of the present invention to solve the deficiency of the existing technology and provide machines before a kind of active upspring type
Cover hinge realizes pedestrian protecting function, simple, light-weight with product structure, two mounting surface directions of cover hinge before permission
Unanimously.
Technical solution：In order to achieve the goal above, cover hinge before a kind of active upspring type of the present invention, including solid
The hinge rotating arm being scheduled on the mounting-fixing base of hinge body side, latch and torsional spring are fixed on hinge by latch rivet pin
On rotating arm, rotation arm support is fixed together with hinge rotating arm by riveting, and sliding pin is fixed on rotating arm by riveting
On stent, sliding slot and limiting flange are additionally provided on the hinge rotating arm.
As present invention further optimization, the hinge body side mounting-fixing base and hinge rotating arm pass through hinge
The rotation riveting of assembly riveting axis links together.
As present invention further optimization, the rotation arm support is riveted solid with hinge rotating arm by tubular rivet
It is fixed, ensure the present invention in use reliability that is normally-open and closing.
As present invention further optimization, the sliding slot is equipped with rotation arm support bushing, the rotating arm branch
Frame bushing is fixed on by flanging process on the sliding slot on hinge rotating arm, which does not slide together with sliding pin, the lining
Set is to ensure sliding pin gapless between each connector after staking in the presence of effect.
As present invention further optimization, the hinge rotating arm is equipped with limiting flange and is located at the one of latch
Side, when hinge does not bounce, rotation arm support pushes down latch, and latch is made not rotate；When hinge bounces, latch is being turned round
30 ° or more are rotated around latch rivet pin under the elastic force effect of spring, latch reaches the position of limiting flange and with limiting flange
It offsets, the height for being bounced the hood bounced maintenance.
As present invention further optimization, the rotation arm support is connected with hood.
As present invention further optimization, the length of the sliding slot is more than 20mm, ensures that hood bounce amount is expired
Sufficient pedestrian protecting requirement, is set as more than 10mm by the width of sliding slot, ensures sliding pin diameter dimension, ensure impact strength.
As present invention further optimization, the sliding pin and rotation arm support between gap for 0.2mm with
On, it fixes sliding pin using riveting process and makes to avoid because of gap existing for longitudinal direction in longitudinal gapless between each connector
Cause vehicle because of tubular rivet 10 by longitudinal shear so as to be happened tubular rivet fracture failure.
Operation principle：Hinge assembly riveting axis is arranged close to the position of driver, and rotating arm is mounted remotely from driver's
Position, rotating arm are connected on hood, and when a vehicle is in a collision, tubular rivet fracture makes hinge rotating arm and rotation
Arm support detaches, and rotation arm support continues to be lifted, and sliding pin is slided and rotated in sliding slot, makes rotation arm support together with engine
Lid is raised to certain altitude together, realizes pedestrian protecting function.When rotating arm support lifting, latch is made in the elastic force of torsional spring
It is rotated under around latch rivet pin, finally offsets with limiting flange, the transmission hood being lifted is prevented to fall, maintain engine
Cover the height being lifted.
Advantageous effect：Cover hinge before a kind of active upspring type of the present invention, makes to start by using sliding groove structure
Cover is lifted and realizes pedestrian protecting function so that hinge for engine hood assembly structure is succinct, and accessory is few, light-weight；Due to this
In invention, allow two mounting surfaces of hood hinge towards on the contrary so that hinge assembly applicability in car body arrangement is broader.

Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is furture elucidated.
As shown in drawings, cover hinge before a kind of active upspring type of the present invention, it includes：It installs hinge body side
Fixed seat (1), the hinge rotating arm (2) being fixed on hinge body side mounting-fixing base (1), is riveted on hinge rotating arm (2)
On rotation arm support (4), riveting is fixed on the sliding pin (5) in rotation arm support (4), solid by latch rivet pin (7)
The torsional spring (8) and latch (9) being scheduled on hinge rotating arm (2).
Embodiment 1
When vehicle collides and starts pedestrian protection system, the jacking device below the present invention sprays lifting pin
It projecting, the lifting pin ejected hits hinge rotation arm support (4), and the impact force of lifting pin is broken tubular rivet (10), from
And hinge rotating arm (2) is made to be detached with rotation arm support (4), the impact force of lifting pin make the rotation arm support (4) after separation after
Continuous lifting, the sliding pin (5) being fixed on rotation arm support (4) are slided and are rotated in the sliding slot (11) preset, make rotation
Arm support (4) is raised to certain altitude together with hood, realizes pedestrian protecting function.
When rotating arm support (4) lifting, latch (9) is under the elastic force effect of torsional spring (8) around latch rivet pin (7)
Rotation.During rotation arm support (4) is lifted, latch (9) is rotated under the elastic force effect of torsional spring (8) and is finally rotated
It offsets to the position of limiting flange (12) and limiting flange (12), prevents to cause to be lifted due to the rapid attenuation of lifting pin top lift
The transmission cover risen falls, the height that hood is maintained to be lifted.
The technical concepts and features of the above embodiment only to illustrate the invention, the purpose is to allow be familiar with the technical field
Technical staff can understand present disclosure and implement according to this, can not be limited the scope of the invention with this.All
The equivalent changes or modifications made according to spirit of the invention all should contain device within protection scope of the present invention.
