Abstract

PROBLEM TO BE SOLVED: To increase the degree of freedom in molding between a hood and a windshield by forming the rear end corner part of a vehicle hood into a deformable structure which is easy to deform into such a shape as a rearwardly protruding degree is released. SOLUTION: In the rear end corner part 10a of a hood 10, a hood inner 14 approaches a hood outer 12, and a bead 14a is formed at the hood inner 14. The rear end corner part 10a and a hood body part 10b except it are partitioned by the bead 14a. The bead 14a is recessed to the hood outer 12 side, and the rear end corner part 10a is formed into a deformable structure which is earlier to deform than the other section of a hood. As a result, it is not necessary to preset the clearance between the hood 10 and a windshield 22 so as to be large, thus it is possible to increase the degree of freedom in molding.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rear end structure of a vehicle hood.

[0002]

2. Description of the Related Art Conventionally, as a structure of a rear end portion of a vehicle hood of this type, a shape of a rear end portion of the vehicle hood is generally formed along a curved shape which is convex forward in a plan view of a windshield. Therefore, the rear end corner portion has a shape protruding rearward.

[0003]

However, if the rear end corner portion has a shape projecting rearward, the hood may hit the windshield and break the windshield when the hood retreats in the event of a collision. However, there is a problem that the repair cost becomes large. In order to avoid such a problem, it is necessary to increase the gap between the rear end corner portion and the front window glass in advance, and there is a problem that there is a limitation in modeling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and the invention according to claims 1 to 7 is intended to increase the degree of freedom in shaping between a hood and a windshield after a vehicle hood. Its purpose is to provide an end structure.

[0005]

According to a first aspect of the present invention, there is provided a vehicle hood rear end structure in which a rear end corner portion of a vehicle hood is formed so that the degree of rearward projection is reduced. It is characterized by an easily deformable structure that is easily deformed. According to a second aspect of the present invention, in the first aspect, the easily deformable structure is a structure in which a rear end corner portion is easily bent downward along a bead formed on the back surface of the hood. It is characterized by the following.

According to a third aspect of the present invention, in the first aspect, the easily deformable structure includes a rear end corner portion of the hood formed of a separate part separate from the hood main body. It is characterized in that parts have a structure that can easily fall off the hood body. According to a fourth aspect of the present invention, in the third aspect, the separate component has a vertical wall extending below an edge of a rear end corner portion of the hood and covering at least a part of the hood hinge. It is characterized by the following.

According to a fifth aspect of the present invention, in the third or fourth aspect, a contour of a rear end corner portion of the hood main body in a state where the separate component is dropped is closer to a front window glass side in a plan view. It is characterized by having a curved shape that is convex. The invention according to claim 6 is
6. The device according to claim 1, wherein a blocking member is provided below a rear end corner portion of the hood having the easily deformable structure so as to prevent deformation of the easily deformable structure at normal times. And According to a seventh aspect of the present invention, in the sixth aspect, the blocking member is a cushioning member mounted on a head of a hood hinge.

[0008]

According to the first aspect of the present invention, even when the hood comes into contact with the windshield during a collision, the rear end corner of the hood is easily deformed by the reaction force received from the windshield. Since the structure is deformed and the degree of rearward projection is reduced, it is possible to prevent the rear end corner portion from breaking the windshield. Therefore, the gap between the rear end corner of the hood and the front window glass can be set freely, so that the degree of freedom in modeling can be increased.

According to the second aspect of the present invention, in addition to the effect of the first aspect, since the bead is formed, the rear end corner portion is bent downward by using the bead as a trigger, so that it is ensured. The shape can be changed to a shape in which the degree of protrusion backward is reduced. Since the beads are formed on the back surface of the hood, they do not deteriorate the appearance. According to the third aspect of the invention, in addition to the effect of the first aspect, the separate component is dropped from the hood main body,
Deformation can be reliably made into a shape in which the degree of rearward projection is reduced.

According to the fourth aspect of the present invention, in addition to the effect of the third aspect, since the separate component has the vertical wall covering at least a part of the hood hinge, the hood, the vehicle body and the vehicle body can be normally put on. The hood hinge can be prevented from being fully exposed from the gap between them, and the appearance can be improved.
According to the invention of claim 5, according to claim 3 or 4,
In addition to the effects described above, after the separate component falls off, the rear end corner of the hood body has a curved shape that is convex toward the windshield, so that the sharp shape faces the windshield. Therefore, even if the hood body further retracts and hits the windshield after the separate component has fallen, it is possible to prevent the windshield from breaking.

According to the invention described in claim 6, in addition to the effect according to any one of claims 1 to 5, a blocking member provided below the rear end corner portion of the hood allows a person to be in a normal state. It is possible to prevent the easily deformable structure from being deformed when the hood is in the normal position range, such as when the hood is touched or the hood is waxed.

According to the seventh aspect of the present invention, in addition to the effect of the sixth aspect, since the blocking member is a cushioning member mounted on the head of the hood hinge, it is easily deformed in normal times. When a force is applied from above, the easily deformable structure can be supported while buffering the force. Also,
Since the cushioning member covers a part of the hood hinge, the hood hinge is difficult to be directly seen from the gap between the hood and the vehicle body, and the appearance can be improved.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 are views showing a first embodiment of a vehicle hood rear end structure of the present invention. In the drawing, reference numeral 10 denotes a hood for covering the engine room of the vehicle from above, and a hood outer 12 serving as a surface of the hood.
And a hood inner 14 disposed on the back side of the hood. The hood outer 12 and the hood inner 14 form a closed sectional structure 13 at an appropriate position of the hood 10 to maintain the rigidity and strength of the hood 10, and at each end, the hood inner 14 is attached to the hood outer 12. At the same time, the terminal of the hood outer 12 wraps around the terminal of the hood inner 14 and is hemmed and joined. Also at the rear end corner 10a of the hood 10,
The food inner 14 is approaching the food outer 12,
Hood inner 1
4, a bead 14a is formed. This bead 14a
Thereby, as shown in FIG. 2, the rear end corner portion 10a and the other hood main body portion 10b are separated. The bead 14a is recessed toward the hood outer 12 side,
Due to this bead 14a, the rear end corner portion 10a has an easily deformable structure that is more easily deformed than other portions of the hood.

Below the rear corner 10a of the hood 10, there is provided a hood hinge 16 for supporting the hood 10 so that it can be opened and closed with respect to the vehicle body. The hood hinge 16 is a vehicle body side link 1 bolted to the cowl top upper 24.
7 and a hood-side link 18 rotatably mounted on the vehicle-body-side link 17 by a hinge pin 19 and fixed to the hood inner 14 by bolts. And
At the head of the hood hinge 16 above the hinge pin 19, a buffer member 20 as a blocking member is mounted. The buffer member 20 is made of a soft elastic material made of rubber or synthetic resin. The buffer member 20 may always contact the rear end corner 10a of the hood 10, or a slight gap may be provided between the buffer member 20 and the rear end corner 10a.

In the rear end structure of the vehicle hood configured as described above, when the hood 10 moves rearward and comes into contact with the front window glass 22 at the time of a collision, as shown in FIGS. The reaction force received from the window glass 22 causes the rear end corner 10
a bends downward with the bead 14a as a trigger. As a result, the degree of rearward projection of the rear end corner portion 10a is reduced, so that the hood 10 is
The front window glass 22 does not break even if it comes into contact with 2. Particularly, since the bent outer surface portion is always a curved surface, a sharp shape does not face the windshield 22. Therefore, it is not necessary to previously set the gap between the hood 10 and the front window glass 22 large, and the degree of freedom in modeling can be increased.

When a person applies a hand to the rear end corner portion 10a of the hood 10 or waxes the rear end corner portion 10a, a force from above is applied to the rear end corner portion 10a. When the hood 10 is in the normal position range, the buffer member 20 below supports the rear end corner portion 10a while absorbing the force from below, so that the rear end corner portion 10a is bent carelessly. It does not give the worker any feeling of stickiness. Also, in normal times, since the cushioning member 20 covers the head of the hood hinge 16, the hood hinge 16 is difficult to be directly seen from the gap between the hood and the vehicle body, and the appearance can be improved.
For this purpose, the cushioning member 20 is connected to the hood side link 18.
The hood hinge 16 can be provided widely so as not to hinder the rotation of the hood.

Next, a second embodiment of the rear end structure of the vehicle hood according to the present invention will be described with reference to FIGS.
The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. In the present embodiment, the rear end corner 10a of the hood is formed of a separate part 26 made of a synthetic resin separate from the hood main body 10b of the hood, and this separate part 26 is formed by the hood inner of the hood main body 10b. One point is fixed to 14 by a clip 28. Thereby, the separate component 26 has an easily deformable structure in which the separate component 26 easily falls off from the hood main body 10b.

The separate part 26 is provided at the normal rear end corner 10.
a, and has a vertical wall 26a extending downward from the rear edge and the side edge, and covers at least the head of the hood hinge 16. For this reason, it is possible to prevent the hood hinge from being fully exposed from the gap between the vehicle body and the hood 10, and it is possible to improve the appearance.

The hood main body 10b has a rear end corner profile in a state where the separate component 26 is not attached.
It has a curved shape protruding toward the front window glass 22 in plan view. Even in the rear end structure of the vehicle hood configured as described above, when the hood 10 moves rearward and comes into contact with the windshield 22 at the time of collision, as shown in FIG.
The separate component 26 falls off due to the reaction force received from the second member. For this reason, the degree of protrusion of the rear end corner portion 10a toward the rear is reduced, and the contour of the rear end corner portion of the hood main body portion 10b after the separate component 26 is dropped is curved, so that the sharpness is sharp. The shape does not face the windshield 22, so that even if the hood main body 10b further retracts and hits the windshield 22, the windshield 22 will not be broken. Also,
Under normal conditions, the buffer member 20 prevents the separate component 26 from falling off.

FIG. 8 shows a third embodiment of the vehicle hood rear end structure of the present invention. In this embodiment,
As the hood hinge, a hood hinge 30 adapted to the jumping hood is used, and such a rear end structure of the jumping hood is formed by the same bead 14 as in the first embodiment.
a is provided to provide an easily deformable structure. This bouncing hood detects a collision between a vehicle and an obstacle, and detects the collision between the vehicle and an obstacle.
0 jumps from the vehicle body and the obstacle
This is to protect the obstacle by absorbing and relaxing the impact of the obstacle when the vehicle falls down and makes a secondary collision with the vehicle. The same problem exists that the front window glass 22 is damaged when the hood 10 retreats and comes into contact with the front window glass 22 in a state of being flipped up. Therefore, such a problem can be solved by providing an easily deformable structure.

FIG. 8 shows a state in which the hood 10 is flipped up by an actuator (not shown). The hood hinge 30 includes a vehicle body side link 32 bolted to the cowl top upper 24 and a hood inner 14.
Hood-side link 34 bolted to the body, and an intermediate link 3 connecting the vehicle-body-side link 32 and the hood-side link 34
6 and the intermediate link 36 is connected to the hinge pin 3
8 and is rotatably connected to the hood side link 34 by a movable pin 40. The movable pin 40 is movable along an elongated hole 32 a provided in the vehicle body side link 32. On the vehicle body side link 32,
A swing member 42 is attached to the rear end of the swing member 42 so as to be swingable by a pin 44, and a hook portion 42a for accommodating the hinge pin 38 is formed at the tip of the swing member 42. The swing member 42 is always held by its hook 4
2a is urged in the direction to accommodate the hinge pin 38, and holds the hinge pin 38 at the position of the imaginary line. However, when the actuator is actuated and a force is generated that causes the hood 10 to jump upward, the pin 2 is rotated about the pin 44. Then, the hinge pin 38 of the intermediate link 36 is released from the hook portion 42a. At the same time, the movable pin 40 moves backward through the long hole 32a, the intermediate link 36 stands up, and the hood 10 jumps up.

In this state, when a rearward force acts on the hood 10, the rear end corner portion 10a comes into contact with the front window glass 22, but the bead 14a
Is formed, and the rear end corner portion 10a is bent downward by using the bead 14a as a trigger, so that damage to the front window glass 22 can be prevented. In the third embodiment, the rear end corner portion 10a of the hood 10 may be replaced with the bead 14a as a separate component 26, which is the same as in the second embodiment, to have an easily deformable structure.
