Abstract

The present invention relates to a hinge for hinging a front cover or a rear cover to a support structure of an automobile, the hinge incuses a lower part (2) capable of being rotatablely connected with a upper part (3) of the hinge by a pin (4), wherein the lower part (2) is fixed on the support structure with at least a bottom plate. In order to design according to desired capability in head impact of the hinge, the bottom plate separates in horizontal direction of the automobile, wherein upright arm segments (8, 9) of each bottom plate segment meat in a common zone (10) in an installation zone of the pin (4).

Description

Hinge

Technical field

The present invention relates to a kind of being used for is hinged on the hinge on the supporting construction of automobile with front shroud (Fronthaube) or back shroud.

Background technology

Known in large-scale auto manufacturing, a kind of hood hinge that is used for the automobile of head impact situation of design in the structure of pedestrian protection.Must guarantee to be no more than critical HIC-value in addition.

By the known such one type of hood hinge of DE 100 03 624 B4, it has a hinge top and a hinge bottom that is connected through common pin joint.The bed plate of said hinge bottom lies in a horizontal plane on the longeron that belongs to the automobile supporting construction, and is built into and is bent upwards.Like this, when front shroud generation head impact, hinge top reduces downwards, until top, longeron zone.This solution is specially adapted to have the body structure structure of narrow structure space.

Summary of the invention

Task of the present invention is, further improves hinge, the opening and closing that make said hinge can bear front shroud or back shroud, and when head impact, still can carry out the required adjusting of performance.

According to the present invention, this purpose will realize through following 1 hinge, and 2-6 is a preferred implementation of the present invention:

1. with the supporting construction articulated hinges of a front shroud or back shroud and automobile; It has a hinge bottom; This hinge bottom rotatably is connected with a hinge top through a pin, and wherein said hinge bottom is fixed on the supporting construction, wherein with at least one bed plate; Said bed plate separately, wherein can be incorporated into a common zone from the make progress arm section of erect of each bed plate section in the installation region of pin on the longitudinal direction of automobile.

2. above-mentioned 1 hinge wherein, is provided with deformed region, and deformed region makes hinge top descend to the direction of hinge bottom.

3. above-mentioned 2 hinge, wherein, said deformed region is arranged on the arm section.

4. above-mentioned 2 or 3 hinge, wherein, said deformed region constitutes arch respect to one another separately.

5. the hinge of one of above-mentioned 1-4 wherein, is erect a baffle plate from the hinge bottom, concurs with the corresponding baffle plate on hinge top.

6. the hinge of one of above-mentioned 1-5, wherein, the arrangement of on lateral direction of car, staggering each other of the lower area of arm section.

According to the present invention, the hinge bottom is fixed on the supporting construction by means of a bed plate that separates along automobile longitudinal, particularly is fixed on the longeron.From each bed plate section arm section of erect (Armabschnitt) that all makes progress.The arm section of upwards erectting can be combined in the common zone in the installation region of pin.This has an advantage, and promptly hinge can more easily be made, and in addition, can when hinge movement, the adjustment through the arm section obtain meticulous adjusting.Therefore, each arm section for example can have the deformation that different widths also differs from one another.In addition, the appearance profile line (Verlauf) of each arm section can constitute differently, to influence the deformation nature of whole hinge.

For making pin can on the arm section, deformed region be set to the direction motion of hinge bottom.Equally, the deformed region in each arm section can constitute differently.

When each deformed region of arm section constituted arch respect to one another, the arm section can fold with the mode of mutual qualification (definiert aufeinander), and can make pin that almost vertical motion takes place.

In order to limit front shroud or back shroud rotatablely moving when opening, can erect a baffle plate in the hinge bottom, this baffle plate concurs with the corresponding baffle plate on hinge top.

Description of drawings

Below will be elucidated in more detail with reference to the drawing other favourable design schemes of the present invention.Wherein

Fig. 1 is from the phantom drawing of the hinge of oblique forward observation;

The vertical view of Fig. 2 Fig. 1 hinge;

The elevation of Fig. 3 Fig. 1 hinge; And

Fig. 4 is in the hinge of the Fig. 1 in the rigging position.

Specific embodiments

According to Fig. 1, a kind of hood hinge 1---hereinafter is called hinge simply---and comprises a hinge bottom 2 and a hinge top 3.The two rotatably connects through pin 4 each other, so that hinge top 3 can be according to direction of arrow A around the rotation that is made up of pin 45 rotations.

The hinge bottom 2 of being fixed in the body in white side comprise two vertically separate, the bed plate section 6 and 7 of horizontal alignment almost.All upwards draw an

arm section

8 and 9 that vertically stretches from each bed plate 6 or 7, wherein the upper end of two arm sections has a common zone 10 in pin 4 zone

junctions.Arm section

8 and 9 lower area 11 and 12 have a spacing a each other and carry out the transition to bed plate 6 or 7 separately from transversely seeing of automobile, and wherein said bed plate 6 goes out an about spacing a than bed plate 7 is wide.On two

arm sections

8 and 9, between common region 10 and lower area 11 and 12, form deformed region 13 and 14 partly.

Hinge top has a supporting member 19 that is used for fixing the approximate horizontal extension of hood.This horizontal supports 19 carries out the transition to a vertical connector 20 at it on the side of vehicle outside.Connector 20 is used to hold pin 4, and has the baffle plate 21 corresponding baffle plates 22 with hinge bottom 2, baffle plate 22 restriction hinge tops according to direction of arrow A with shown in phantom drawing shown in clockwise direction rotate.

Especially, as knowing in the vertical view among Fig. 2, hinge top 3 constitutes with the automobile middle part angled.

When head impact took place, hinge 1 is done following motion: the power F that is for example brought by dummy's head impelled hinge top 3 to move in the same way.Hinge top, path 3-pin 4-hinge bottom 2 through power the power on

arm section

8 and 9 of acting on produces deformed region 13 and 14 to be out of shape, and in this case, arm section self folds.The zone of also promptly pinning around 4 almost vertically descends towards the direction of bed plate 6 and 7 downwards, and decline can not surpass longeron.

Fig. 4 clearly show that the rigging position of hinge 1.Two bed plate sections 6 and 7 are fixed on the longeron 25 by means of fixed part 23 and 24.Front shroud 26 is fixed on the hinge top 3.

See that from travel direction having one in bed plate section 7 at the back is partial to back upper place extension junction plate 27 at an angle in the vertical.This junction plate 27 is used to receive a dashboard connector that matches.
