DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door check mounting structure provided at substantially the same position as a door hinge for a vehicle.

[0002]

2. Description of the Related Art Door checks that regulate the degree of opening of a door include:
The door and the pillar are provided independently of the door hinge. In this door check, when the door is opened, a large force acts on the pillar portion of the vehicle body, which is the fixed side of the door check, so that the pillar portion needs to be reinforced. Japanese Patent Application Laid-Open No. 5-201254 discloses a door check mounting structure in which a door hinge having a high mounting strength with respect to a pillar portion is integrally provided with a door check fixing side.
According to this publication, a check arm is rotatably provided on a side of a hinge pin of a hinge fixed side bracket via a support pin, and an insertion hole through which a movable end of the check arm is inserted is provided in the hinge movable side bracket. A holder for holding the movable end of the arm is provided so as to face an insertion hole provided inside the hinge movable side bracket.

[0003]

However, in the above-described door check mounting structure, since the holding member is provided on the hinge movable side bracket, the distance between the holding member and the pillar portion is small, and when the check arm is operated. The check arm may interfere with the hinge pin, which limits the operating range of the check arm. Therefore, there is a problem that it is difficult to increase the opening of the door. Also,
In the door check mounting structure described above, in order to maintain the door check mounting strength and increase the door opening, it is necessary to increase the distance between the door and the pillar portion or to increase the movable end of the check arm. Although a method of extending the length is conceivable, both methods have a problem that the door hinge and the door check become large. Furthermore, the holding body is provided on the hinge movable side bracket,
There is a problem that the hinge movable side bracket becomes large.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a door check mounting structure capable of increasing a door opening without increasing the size of a hinge or a door check while maintaining the door check mounting strength. .

As shown in FIGS.
Is formed of a metal plate and extends in the vertical direction of the door 1. The hinge panel 7 protrudes toward a cross member 18 provided on the vehicle body 14.
The hinge panel 7 is bent so as to have a substantially U-shaped cross section, and has a front edge portion 7a, a front wall portion 7
b, a side wall 7c, a rear wall 7d, and a rear edge 7e.

In the vicinity of the upper end of the hinge panel 7, the front end of the side door beam 9 is joined to the front wall 7b, and the rear edge 7
e is fixed to an inner side surface 9B which is one side surface of the side door beam 9 by a rivet 19A. The vicinity of the lower end of the hinge panel 7 is also similar to the vicinity of the upper end of the hinge panel 7,
The hinge panel 7 and the side door beam 10 are fixed to each other by coupling and rivets 19A.

The front edge 7a is provided with the edge 5 of the outer panel 5.
a is attached by a screw 16. The front wall 7b has an opening 7 for inserting the movable bracket 11A.

The side wall 7c is separated from the side door beams 9 and 10 by a predetermined distance, and is formed as a bulging portion between the side door beams 9 and 10 by the front wall 7b, the side wall 7c and the rear wall 7d. 20 are formed. In other words, the cross-sectional shape of the portion where the hinge panel 7 and the side door beams 9 and 10 are fixed to each other near the upper end portion and the lower end portion of the hinge panel 7 is the front wall portion 7b, the side wall portion 7c, the rear wall portion 7d and The inside surface 9B of each of the side door beams 9 and 10 forms a closed cross section, and this portion has a highly rigid structure.

A check case 32 is fixed to the inner side surface of the front wall 7b, and the check case 32 is disposed in the space 20. Check case 32
However, the fixing strength of the check case 32 is improved by being fixed to the front wall portion 7b forming one side surface of the closed cross section. Since the periphery of the check case 32 is covered by the front wall portion 7b, the side wall portion 7c, the rear wall portion 7d, and the inner side surfaces 9B of the side door beams 9, 10, water and dust entering the door 1 are prevented from entering the check case 32. Adhesion can be prevented. Therefore, the check case 32 can maintain its operation characteristics over time.

The front end portions of the side door beams 9 and 10, the space portion 20 and the cross member 18 are disposed substantially on the same straight line in the vehicle width direction, that is, when viewed from the outside of the vehicle body 14, the side door beams 9 , 10 are arranged to face the cross member 18 respectively. With this arrangement, the impact force from the side of the vehicle body 14 at the time of a side collision is absorbed by the buckling of the space portion 20, and the impact force that cannot be absorbed by the buckling deformation is absorbed by the side door beam. 9,
The power is transmitted to the cross member 18 via the reference numeral 10. Therefore,
The deformation of the door 1 can be suppressed.

In the configuration described above, the check case 32
Since it is attached to the front wall 7b of the hinge panel 7, a predetermined space is formed between the movable end 31b of the check arm 31 and the hinge pin 11C. The check arm 31 does not interfere with the hinge pin 11C, the operation range of the check arm 31 can be set sufficiently, and the opening of the door 1 can be increased.

Since the base end 31a of the check arm 31 is fixed to the vehicle body 14 via the fixed bracket 11B and the pillar reinforce 15, the rigidity of the mounting portion is strong, and when the door 1 is opened. Is applied to the check arm 31, the force can be sufficiently received. Since the front wall 7b of the hinge panel 7 forms a part of the closed cross section, the mounting strength of the check case 32 can be improved, and the force when the door 1 is opened can be sufficiently received. Therefore, the mounting strength of the door check 30 can be improved while preventing the door hinge 11 and the door check 30 from being enlarged, and the opening degree of the door 1 can be increased.

Since the check case 32 is attached to the front wall 7b of the hinge panel 7, the door hinge 11
Check arm 31 regardless of the mounting position and shape of the
The check case 32 can be disposed at a position in consideration of the operation range. The inside of the lower end of the hinge panel 7
Since the hinge panel 7 is covered by the inner panel 6, the shape of the lower end of the hinge panel 7 can be made simple, and the mounting position of the door hinge 11 on the lower end side of the door 1 can be lowered. (See Fig. 2)
Can be expanded.

In the above-described embodiment, the door check of the door on the right front side of the vehicle body has been described. However, the door check of the door on the front left side of the vehicle body is formed in a symmetrical shape with the door check of the door on the right front side of the vehicle body. The door check of the front left door of the vehicle body has the same effect as the door check of the front right door of the vehicle body. The mounting structure of the door check described in the above embodiment may be used for the door on the rear side of the vehicle body.

[0022]

Is formed, interference of the movable end of the check arm with the door hinge is prevented, the operating range of the check arm can be set sufficiently, and the opening of the door can be increased. Also, since the base end of the check arm is attached to the vehicle body via the fixed side bracket of the door hinge, the mounting rigidity of the base end is strengthened, so that the force when the door is opened acts on the check arm. , Can fully receive the power. Furthermore, the hinge panel holding the movable end of the check arm is fixed to the front part of the side door beam and swelled toward the inside of the door, so the cross-sectional shape of the fixed part between the hinge panel and the side door beam is reduced. , It becomes a closed section with the side door beam as one side,
The rigidity of the hinge panel becomes strong. Therefore, even if force acts on the hinge panel when the door is opened, to prevent deformation of the hinge panel, it is possible to receive sufficiently the force. Therefore, the mounting strength of the door check can be improved, and the degree of opening of the door can be increased without increasing the size of the door hinge and the door check. That is, it is possible to achieve both an improvement in the mounting strength of the door check and an increase in the door opening.

According to the invention of claim 2, the hinge panel, while extending in the vertical direction of the door, since the arranged directly opposite the cross member, the impact force from the side of the vehicle body in a side collision, the hinge The closed cross section of the panel is absorbed by buckling and transmitted to the cross member via the side door beam. Therefore, the deformation of the door can be suppressed.
