Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an engine cover device for a capover type vehicle.

Conventional technology Generally, in a capover type car, an engine cover is provided between the engine room and the single compartment for maintenance and inspection purposes. Due to the installation of seat belt anchors,
It is necessary to prevent the vehicle from projecting forward in the event of a frontal collision.

An example of an engine cover device having a forward protrusion prevention function will be described with reference to FIGS. A low stepped crotch portion 2 and an extending portion 3 formed on the side of the crotch portion 2.
- The rear part of the crotch part 2 is supported by a pair of hinges 5 on a vehicle body panel 6, and the rear end of the hinge arm 4 is attached to a pillar 7 at a position aligned with the hinge 5. Bolt 8. It is supported via collars 9 and 10.

Further, a seatbelt anchor 12 of a seatbelt 11 is installed in the crotch portion 2.

The crotch portion 2 and the front end of the hinge arm 4 are prevented from opening by a locking device 13.

The extension portion 3 is provided with a retaining hole 14, and a hook 15 provided on the vehicle body panel 6 is inserted into the retaining hole 14. This structure is designed to reliably prevent the engine cover body 1 from protruding forward even when a forward force is applied through the belt anchor 12. 92

Problems to be Solved by the Invention Although it is possible to prevent the engine cover main body 1 from protruding forward by reliably engaging the engagement hole 14 and the hook 15, the seat belt anchor 12 is During a collision, a diagonally upward and forward force acts on the hinge 5. A moment in the opening direction acts on the engine cover body 1 around the hinge point of the hinge arm 4,
Therefore, it has been pointed out that the hook 15 may not engage with the engagement hole 14 in some cases.

In particular, on the hinge arm 4 side of the engine cover body 1, the hook 15. Since the hinge point of the hinge arm 4 is located higher than the position of the engagement hole 14 and is offset, the moment is strong and the engine cover main body 1 easily comes off from the hook 15.

On the other hand, if the clearance between the hook 15 and the engagement hole 14 is made as small as possible, the above problem will be solved, but this will prevent assembly errors and ensure accurate dimensional accuracy. If not, there will be a problem that the hook 15 may interfere with the engagement hole 14 when opening and closing the engine cover body 1.

Therefore, the present invention provides a cap-over type vehicle with a simple structure, which can reliably prevent the engine cover body from protruding forward in the event of a frontal collision of the vehicle, and which does not hinder the opening and closing of the engine cover body during maintenance and inspection. An engine cover device is provided.

A workaround to solve the problem: While the rear part of the engine cover body where the seat belt anchor is installed is supported by the vehicle body side member by twisting the hinge, it is also possible to install it on either the vehicle body side member or the engine cover body. In an engine cover device for a cap-over type vehicle, in which a hook is inserted into a retaining hole for preventing forward protrusion provided on the other side, at least one of the hinges is attached to either one of the vehicle body side member and the engine cover main body. A support shaft provided on the other side and a holding hole for the support shaft provided on the other side, the holding hole is formed from a movement allowance hole and a rotation hole, and a hole is formed between the movement allowance hole and the rotation hole. When opening and closing the engine cover main body, the movement permissible hole and the rotation hole are separated, the support shaft is prevented from moving to the movement permissible hole, and the support shaft is held rotatably. The structure includes a shaft support that deforms when a load exceeding a predetermined forward load is applied to the engine cover, allowing the support shaft to move into the movement permitting hole, and allowing the engine cover body to move forward. .

Effect When a load greater than a predetermined load is applied to the seat belt anchor during a frontal collision of the vehicle, the support shaft provided on at least one of the hinges that supports the engine cover body at the rear part rotates with the movement permissible hole. Deforming the shaft support provided between the hole and dividing the holding hole of the support shaft to move to the movement permitting hole and allowing forward movement of the engine cover body;
As a result, the hook provided on either the engine cover main body or the vehicle body side member engages with the engagement hole provided on the other.
