Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a structure of a hood hinge to which a hood stopper can be easily attached to prevent the hood from moving with respect to a vehicle body in the event of a collision and preventing the hood from hitting the windshield.

[Prior art and its problems]

Currently, vehicle safety standards are not unified worldwide and are set separately in each country. When exporting the same model of automobile to different countries around the world, the specifications of the vehicle must be changed to comply with each country's safety standards. One of the safety standards is that a mechanism must be provided to prevent the rear end of the hood from moving backwards and colliding with the windshield in the event of a frontal collision. As a mechanism for complying with such standards, for example, a mechanism as shown in Japanese Utility Model Application Laid-Open No. 55-153279 has been proposed. This is a mechanism in which a hood stopper is erected on a cowl top panel to which a reinforcing member is attached, and a locking hole is provided in the hood with which the hood stopper engages when the hood is closed. Therefore, in the event of a frontal collision, a force is applied to move the hood rearward, but
The locking hole of the hood is engaged with the hood stopper, so that when the hood moves relative to the vehicle body, it does not get stuck and the rear end of the hood does not collide with the windshield. However, when producing the same model of vehicle for export to countries that have the above-mentioned safety standards and countries that do not, the following problems arise. In other words, if the hood stopper shown in the above-mentioned publication is provided, a mounting hole or the like is required to attach it to the cowl top panel, but if the hood stopper is not provided, a hole or the like is required to be provided in the cowl top panel. There is no need to provide one. Therefore, two types of cowl top panels are required for the same vehicle model, which causes a corresponding increase in production costs, posing a problem. Furthermore, when the above-mentioned hood stopper is provided, the force applied to the hood stopper through the hood in the event of a frontal collision is quite large, so the reinforcing member provided to the cowl top panel should be of high strength. This also caused an increase in production costs. This invention was devised due to the above-mentioned circumstances, and countries that require the above-mentioned safety standards,
To provide a vehicle that can be produced with one type of cowl top panel even when exporting the same model of vehicle to a country that does not have the same type of vehicle, and the production cost is significantly reduced.

[Means to solve the problem]

In order to solve the above-mentioned problems, in the present invention, a hood hinge housing is fitted and fixed into a holding hole drilled in the front wall of the cowl top panel, and a hinge arm with a hood fixed to the tip is installed inside the hood hinge housing. In a hood hinge structure in which a base is pivotally housed and supported, an outward flange is provided around the front opening of the hood hinge housing, and the outward flange and the base of the hood stopper are fastened together with bolts. It is fixed to the front wall of the cowl top panel.

[Operation and effects of the present invention]

In the present invention, an outward flange is provided around the front opening of the hood hinge housing, and the outward flange and the base of the hood stopper are fixed together with bolts to the front wall of the cowl top panel. Therefore, a bolt through hole for attaching the hood hinge housing;
Since it can also be used as the bolt through hole for attaching the hood stopper, there is no need to provide a dedicated hole for the hood stopper as in the past. Therefore, in the same vehicle model, it is possible to attach or not attach a hood stopper to one type of cowl top panel, making it extremely easy to change specifications. As a result, production costs can be significantly reduced. Furthermore, when providing a hood stopper, the hood stopper is attached so as to overlap the outward flange of the hood hinge housing, so this outward flange serves as a conventional reinforcing member, and there is no need to provide a separate reinforcing member as in the conventional case. This also contributes to a reduction in production costs, since there are no

[Explanation of Examples]

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The front wall 1a of the cowl top panel 1 facing the engine room has a pair of left and right holding holes 2, as clearly shown in Figure 3, and the hood hinge A is attached by fitting into these holding holes 2. It's becoming like that. The hood hinge A has a hood hinge housing 3 in which an outward flange 4 is formed at the front opening, and a hinge arm 7 that is housed and supported inside the housing so as to be rotatable about a support pin 8. By fitting the hood hinge housing 3 into the holding hole 2 and tightening the bolt 11 passed through the bolt through hole 5 formed in the outward flange 4 to the nut 11a provided behind the front wall 1a of the cowl top panel 1, It is adapted to be attached to the cowl top panel 1. An inner panel 6a of the hood 6 is fixed to the tip of the hinge arm 7. On the other hand, the hood stopper 9 is a member having a hook-shaped head 9a at the upper end and a plate-shaped mounting base 9b that can be stacked on the outward flange 4. Through-holes 10 corresponding to the two upper and lower bolt through-holes 5 are bored. As is clear from the figure, when fixing the hood hinge housing 3, the hood stopper 9 is designed so that its mounting base 9b is overlapped with a predetermined portion of the outward flange 4 of the hood hinge housing 3. It can be easily installed by simply tightening a bolt 11 inserted into a through hole 10 and a bolt through hole 5 in communication with a nut 11a located behind the inner panel 1a. When the hood stopper 9 is attached, as shown in FIG. 2, when the hood 6 is closed, the hook-shaped head 9b of the hood stopper 9 always locks into a predetermined portion of the inner panel 6a of the hood 6. It protrudes into the hole 12. Therefore, for example,
Even if the hood 6 attempts to move rearward due to the impact of a frontal collision, the locking hole 12 of the hood 6 catches the head 9b of the hood stopper 9, thereby reliably preventing the hood 6 from moving. As described above, in the structure of the hood hinge A of the present invention, the hood stopper 9 is fixed to the front wall 1a of the cowl top panel 1 in a co-tight manner with the outward flange 4 of the hood hinge housing 3. There is no need to make any special modifications to the cowl top panel 1 to attach the cowl top panel 9, and therefore, a single cowl top panel can be used for specifications with a hood stopper and specifications without a hood stopper. In addition, since the hood hinge housing 3 with the outward flange 4 formed around the opening is used as the hood hinge A, and the hood stopper 9 is attached so as to overlap the outward flange 4, the hood hinge housing 3 is attached with a mounting means. The outward flange 4 also functions as a reinforcing member for attaching the hood stopper 9, and therefore, sufficient attachment strength can be obtained without preparing any special reinforcing structure for the hood stopper 9. After all, the hood stop can be easily installed when installing the hood hinge housing without having to take any reinforcement or attachment measures, which means that the hood stop is required and the hood stop is not required. This means that specifications can be changed with minimum cost and with good workability.
