Problems solved by technology

[0004] However, in the above-mentioned structure, there is a problem that it is necessary to support the arm portion of the elastic member having the shaft support on the bracket attached to the vehicle body side member in a swingable manner, and at the same time provide a mechanism for pressing the above-mentioned arm portion forward. The spring and the above-mentioned folding part that prevents the arm from tilting back, etc., make the structure very complicated

Embodiment approach 1

[0073] figure 1 Shown is a front vehicle body having a vehicle hood stopper structure of the present invention. A hood 5 for opening and closing the upper end opening of the engine compartment 4 is provided on the front front body. It is surrounded by a front fender panel (front fender panel) 2 at the top and a dash panel (dash panel) 3 at the rear.

[0074] The engine cover 5 can be operated by swinging the engine cover hinge 6 provided between the lower side of the rear end portion and the upper surface of the rear end portion of the front fender 2 as a fulcrum, so that the upper opening of the engine room 4 can be opened. Changes between the two states of closed or open are possibly supported. In addition, between the lower surface of the front end portion of the hood 5 and the upper surface of the front cover 1, an engine hood locking device (not shown) is provided to keep the hood 5 in a closed state, and the front cover 1 1 are provided with stoppers 7 that function a...

Embodiment approach 2

[0095] Figure 9 A second embodiment of the present invention is shown in which the lower end portion of the first leg portion 11 of the support bracket 8 is fixed to the rear upper surface of the cowl panel 1 . In the second embodiment, when the engine cover 5 is closed, the stopper 7 supported by the support bracket 8 is prevented from being plastically deformed by preventing the first and second leg portions 11, 12 of the support bracket 8 from being plastically deformed. Elastic deformation can absorb the impact energy generated when the engine cover 5 is closed, and in the event of a collision accident in which a pedestrian's head hits the engine cover 5, etc., a certain value or more of the load will move along the direction from the oblique front upper side to the rear lower side. When the inclined direction β acts on the support bracket 8, the first and second leg portions 11, 12 of the support bracket 8 are plastically deformed, as shown by the arrow γ, so that the su...

Embodiment approach 3

[0097] Figure 10 A third embodiment of the vehicle hood stopper structure of the present invention is shown. In this third embodiment, the first leg portion 51 of the support bracket 8 is along the input direction β( Figure 11 ) is inclined rearward and downward, and the rear wall portion 27 of the cowl panel 1 is constituted by an inclined surface inclined corresponding to the angle of the first leg portion 51 .

[0098] On the rear portion of the first foot portion 51 upper end portion of the support bracket 8 and the top plate portion 13, a long hole-shaped first slot 32 communicating with the rear edge portion of the support hole 21 of the embedded stopper 7 is formed. The top plate portion 13 is formed with a second slot 33 formed of a U-shaped cutout communicating with the front edge portion of the support hole 21 . Also, on the first leg portion 51 of the support bracket 8, above the through hole 20 (the through portion through which the rod-shaped member can pass) ...

Abstract

A vehicle hood stopper structure, in which a stopper functioning as a buffer when closing the hood located at the front of the vehicle body is provided between the hood and the side member of the vehicle body, which includes a The support portion of the stopper, and the support bracket installed on the vehicle body side member, when a load greater than a certain value or more than the load generated when the hood is closed, acts on the support bracket supported by the support bracket. When the stopper is on, the support bracket is deformed to facilitate the downward movement of the stopper. The present invention effectively absorbs the impact energy when the engine cover is closed by adopting a simple structure, and effectively alleviates the impact load generated when a pedestrian's head hits the engine cover or the like in a collision accident.

Description

technical field [0001] The present invention relates to a vehicle engine hood stopper structure in which a stopper functioning as a buffer is provided between the engine cover and a vehicle body side member when closing the engine cover provided at the front of the vehicle body. Background technique [0002] Conventionally, as shown in the following patent document 1 (Japanese Patent Laid-Open Publication No. Sho 59-6158), a hood damper is provided at the front of the vehicle body to absorb the impact energy acting through the hood. The above-mentioned hood shock absorber includes an arm part that can be erected and supported by a shaft to rotate in the front-rear direction of the vehicle body, and the elastic member installed at the free end of the arm part prevents the arm part at a predetermined forward tilt position from continuing to move forward. Tilt stopper, resistance member for energy absorption when the arm turns to the rear of the ...
