Abstract
Disclosed in the invention is an automotive hood hinge comprising a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, and a fifth connecting rod. The first connecting rod is connected with a hood; and the fourth connecting rod is connected with a vehicle body. A connecting part bending downwardly is arranged at the end portion of one end of the first connecting rod; and the connecting part and the fifth connecting rod are riveted by a rotation rivet. A flange is arranged at the top of the fifth connecting rod and the flange and the lower surface of the first connecting rod are in contact and are connected by a force-limiting rivet. The two ends of the second connecting rod and the third connecting rod are connected to the fifth connecting rod and the fourth connecting rod respectively by rivets. According to the invention, the requirement of normal opening and closing of the hood can be met in a conventional using state; and the lifting motion of the hood rear part can be completed by cooperating with a hood active lifting system in an accident of knocking people down by a vehicle, thereby improving protection of heads of pedestrians by vehicles.
Description
Technical field
The present invention relates to the parts of automobile, more specifically to automobile front hood hinge.
Background technology
In the process of Vehicular impact pedestrian, in order to improve the protection of vehicle to pedestrian head, initiatively liftable front shroud at home and abroad vehicle is applied gradually.But existing Four-connecting-rod hinge is not suitable for initiatively liftable front shroud, its structure as shown in Figure 8, comprise first connecting rod 1, second connecting rod 3, third connecting rod 4 and double leval jib 5, first connecting rod is positioned at above double leval jib, first connecting rod is connected with front shroud, double leval jib is connected with vehicle body, the two ends of second connecting rod and third connecting rod respectively by rivet interlacement on first connecting rod and double leval jib.This hinge only has single center of rotation, front shroud only can be made to realize normal on-off action, but the hinge that initiatively liftable front shroud system requirements is supporting with it can provide extra center of rotation, make front shroud can realize in closed state rear portion upwards lift action.
Summary of the invention
The object of this invention is to provide a kind of automobile front hood hinge, it can realize the opening and closing of front shroud when normal use, can, after shock pedestrian, coordinate lifting apparatus to realize upwards lifting of front shroud rear portion again.
Automobile front hood hinge of the present invention, comprise first connecting rod, second connecting rod, third connecting rod and double leval jib, first connecting rod is positioned at above double leval jib, first connecting rod is used for being connected with front shroud, double leval jib is used for being connected with vehicle body, also comprise the 5th connecting rod, 5th connecting rod is between first connecting rod and double leval jib, the end, one end of first connecting rod is provided with the connecting portion of bending downwards, this connecting portion and the 5th connecting rod are fitted, riveted by swivel rivets between connecting portion and the 5th connecting rod, the top of the 5th connecting rod is provided with flange, this flange and first connecting rod soffit are fitted, and by limiter rivet interlacement, the two ends of second connecting rod and third connecting rod respectively by rivet interlacement on the 5th connecting rod and double leval jib.
Operating principle of the present invention is as follows: under normal service condition, for connecting front shroud first connecting rod and the 5th connecting rod is fixed together by swivel rivets and limiter rivet, define a jointed connecting rod, this jointed connecting rod and other three connecting rods form a Four-connecting-rod hinge structure, make front shroud realize conventional on-off action.When Vehicular impact is to pedestrian time, the sensor being arranged in front part of vehicle can detect collision alarm, and send ignition signal to lifting apparatus by automobile ECU, the push rod that lifting apparatus promotes its inside applies jack-up power to first connecting rod, when the peak value of jack-up power acquires a certain degree, between first connecting rod and the 5th connecting rod limiter rivet just can fracture failure, subsequently under the continuous action of lifting apparatus, first connecting rod rotates around swivel rivets, and then makes front shroud rear portion be realized the action of upwards lifting by this hinge.
Automobile front hood hinge of the present invention; owing to having said structure; both the requirement of the normal opening and closing of front shroud can have been met under normal service condition; in the accident can thrusted at generation car again; coordinate front shroud active lifting system to complete the lifting action at front shroud rear portion, improve the protection of vehicle to pedestrian head.

Detailed description of the invention
In order to explain technical scheme of the present invention further, below in conjunction with accompanying drawing, the present invention will be described in detail.
See shown in Fig. 1 to Fig. 4, this automobile front hood hinge, comprise first connecting rod 1, second connecting rod 3, third connecting rod 4 and double leval jib 5, first connecting rod 1 is positioned at above double leval jib 5, first connecting rod 1 is for being connected with front shroud 15, double leval jib 5 is for being connected with vehicle body 13, the 5th connecting rod 2 is provided with between first connecting rod 1 and double leval jib 5, the end, one end of first connecting rod 1 is provided with the connecting portion 20 of bending downwards, this connecting portion and the 5th connecting rod 2 are fitted, riveted by swivel rivets 7 between connecting portion and the 5th connecting rod 2, the top of the 5th connecting rod 2 is provided with flange 21, this flange and first connecting rod 1 soffit are fitted, and connected by limiter rivet 6, the two ends of second connecting rod 3 and third connecting rod 4 are connected on the 5th connecting rod 2 and double leval jib 5 respectively by rivet 8,9,10,11.
See shown in Fig. 5 to Fig. 7, this automobile front hood hinge coordinates lifting apparatus 12 to use, and lifting apparatus 12 is installed vertically on fixed support 18 by bolt, and fixed support 18 is welded on car body roof side rail 17, roof side rail offers circular hole, to facilitate placement and the installation of lifting apparatus.Under front shroud closure state, uplifting device 12 is in non-duty, and top and the first connecting rod 1 of uplifting device 12 are in contact condition, and its contact position is between limiter rivet 6 and swivel rivets 7.
When Vehicular impact is to pedestrian time, the sensor being arranged in front part of vehicle can detect collision alarm, and send ignition signal to lifting apparatus 12 by automobile ECU, lifting apparatus 12 is by the pyrophoric ignition to its inside, the push rod promoting its inside applies jack-up power to first connecting rod 1, when the peak value of jack-up power reaches 3KN, limiter rivet 6 meeting fracture failure between first connecting rod 1 and the 5th connecting rod 2, under the continuous action of lifting apparatus 12, first connecting rod 1 rotates around swivel rivets 7, and then make front shroud rear portion be realized the action of upwards lifting by this hinge.
