Description
Technical field
The utility model belongs to the functor in motor vehicle body, specifically a kind of connection body of a motor car and engine
The hinge means of lid.
Background technique
Automobile has become the vehicles essential in people's daily life, and the pedestrian protecting performance of automobile is increasingly
It is important, it has been laws and regulations requirement item in Europe, China will formally be included in pedestrian protecting performance in C-NCAP.And vehicle is right
When outer vent, importing country can carry out pedestrian protecting test to vehicle, and the hood product of existing design is difficult to obtain high score,
If outlet cannot be will limit by test.
Mainly comprising shank test and head test in pedestrian protecting regulation, wherein the score of head impact is critically depend on
The arrangement and design of front cover.After pedestrian and front part of vehicle collide, most accidents be after pedestrian and car crass again with hair
Secondary collision, which occurs, for motivation lid causes head severely injured or even fatal.
Free space increase can reduce head injury value (HIC) below hood, master used in advanced automobile manufacturer
Structure is complicated for dynamic formula hinge for engine hood, is chiefly used in high-end vehicle, in structure all based on Four-connecting-rod hinge, design difficulty
Height, occupied space is big, at high cost.Domestic depot mostly uses turning arm type hinge, due to the limitation of structure, in pedestrian's Protection
In be hardly obtained score, and mechanical system there are reliabilities it is low, transmission efficiency is low the problems such as.
Summary of the invention
To make up for the shortcomings of the above existing technologies, engine is actively bounced the purpose of the utility model is to provide a kind of
Cover hinge system realizes the function that hood actively bounces, and reduces the degree that pedestrian comes to harm, reduces cost, occupies empty
Between with using common rotating arm hinge it is identical, facilitate later period maintenance.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of actively bounce hinge for engine hood system
System, including the rotating arm being fixedly connected with hood, the fixed base plate being fixedly connected with body shell, starter, collision sense
Device is answered, is characterized in that arm is bounced in rotating arm flexible connection, arm is bounced by pin shaft and is connected to fixed base plate, pin shaft suit is turned round
Turn spring, torsionspring one end, which is fixed on, bounces on arm, and the other end is fixed on fixed base plate；Setting bar shaped is sliding on fixed bottom plate
Slot, slot is interior to be arranged positioning pin, and positioning pin one end, which is riveted on, bounces on arm；Setting anti-rotating hole I on arm is bounced, is arranged on fixed base plate
Anti-rotating hole II；Contractile front end, contractile front end insertion anti-rotating hole I and anti-rotating hole II is arranged in starter, and starter passes through
Signal wire is connected with colliding sensor.
Further improvement lies in that: the fixed base plate is fixed on chassis runner.
Further improvement lies in that: the rotating arm and bounce the flexible connection between arm for pin shaft connection.
Further improvement lies in that: the starter is fixed in vehicle body upper longitudinal beam.
Further improvement lies in that: the signal wire is arranged in vehicle body cabin.
Further improvement lies in that: the colliding sensor is installed on Chinese herbaceous peony bumper.
The utility model has the beneficial effects that (1) realizes the function that hood actively bounces, buffering is played to pedestrian head
Effect, to reduce the degree that pedestrian comes to harm；(2) occupied space is identical as common rotating arm hinge, is not changing former vehicle
This hinge can be used under the premise of the stringer and Fa Gai of body, provide double leval jib active hinge same function；(3) structure letter
Single, at low cost, mechanical part reduction is simple, and later period maintenance is convenient.

In Fig. 1-Fig. 5: hinge 1, starter 2, signal wire 3, colliding sensor 4, rotating arm 5, rotating dog 6 bounce arm 7,
I 7-1 of anti-rotating hole, positioning pin 8, fixed base plate 9, II 9-1 of anti-rotating hole, torsionspring 10 bounce rotating dog 11, and rotating arm bounces shape
State 12, rotating arm reset condition 13, pedestrian head model 14, the position 15 of hinge means, hood reset condition 16 are started
Cover bounces state 17, bar shaped sliding slot 18, starter front end 19.
Specific embodiment
See Fig. 1-Fig. 5, the present embodiment structure is as follows: hinge for engine hood system is set to hood rear portion.Rotating arm 5
It is fixedly connected with hood, fixed base plate 9 is fixed on chassis runner；Rotating arm 5 bounces arm 7, bullet by the connection of rotating dog 6
Cantilever lifting 7 is connected to fixed base plate 9 by bouncing rotating dog 11, bounces rotating dog 11 and is set with torsionspring 10, torsionspring 10 1
End, which is fixed on, bounces arm 7, and the other end is fixed on fixed base plate 9；Bar shaped sliding slot 18 is set on fixed bottom plate 9, and setting is fixed in slot
Position pin 8,8 one end of positioning pin, which is riveted on, bounces on arm 7；Setting I 7-1 of anti-rotating hole on arm 7 is bounced, anti-rotation is set on fixed base plate 9
II 9-1 of hole；Starter 2 is fixed in vehicle body upper longitudinal beam, and contractile front end is arranged in starter 2, and the insertion of starter front end 19 is anti-
II 9-1 of I 7-1 of turn hole and anti-rotating hole, starter 2 are connected by signal wire 3 with colliding sensor 4, and signal wire 3 is arranged in vehicle body machine
In cabin, colliding sensor 4 is installed on Chinese herbaceous peony bumper.
Working principle of the utility model is: under rotating arm reset condition 13, starter front end 19 be inserted into I 7-1 of anti-rotating hole and
II 9-1 of anti-rotating hole, bounces arm 7 and fixed base plate 9 is relatively fixed.When front part of vehicle bumps against pedestrian, colliding sensor can be generated
Signal passes to starter 2 by signal wire 3, and starter front end 19 is shunk, and bounces arm 7 and fixed base plate 9 relatively movably, is turning round
Under the action of turning spring 10, bouncing arm 7 can rotate around bouncing rotating dog 11, under the action of positioning pin 8, bounced arm 7 and revolved
Stop after going to certain position.It bounces arm 7 and will drive rotating arm 5 and move together, as rotating arm bounces state 12.Work as rotating arm
5 in when bouncing state, and hood will become hood by hood reset condition 16 and bounce state 17, such pedestrian
Head model 14 has very big cushion space when striking hood, can effectively protect the head safety of pedestrian in this way.
Hood is compressed to the position that anti-rotating hole 7-1 and II 9-1 of anti-rotating hole is overlapped in later period maintenance, arm is bounced,
Starter front end 19 is inserted, such hinge 1 is restored to initial state, and required energy storage exists when next time is bounced
In torsionspring 10.
In the process of moving if unexpected bump against pedestrian, front shock inductor 4 can perceive vehicle and bump against pedestrian vehicle
Movement, inductor can control starter 2.Starter 2 excite after, the rotating arm 7 of hinge for engine hood 1 can bounce it is certain away from
From having the space of buffering to pedestrian head in this way, to reduce the degree that pedestrian comes to harm.
There is spring mechanism in active hinge means, hood can be made to bounce rear there are also the effect of buffering, work as pedestrian head
When striking hood, spring is compressed, to play the role of centainly buffering again, can equally reduce the wound that pedestrian is subject to
Evil degree.
