Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a damper structure in a vehicle door such as a tailgate.
[0002]
[Prior art]
The conventional hatch gate anti-vibration structure exemplified in Japanese Utility Model Registration No. 2559483 includes a slope of a hard resin stopper fixed to a hatch gate side and a soft resin stopper fixed to a body side wall when the hatch gate is closed. The upper and lower surfaces are in contact with each other, and the deformation of the lower cavity of the inclined surface of the soft resin stopper absorbs the vibration in the vertical direction or the horizontal direction generated in the hatch gate.
[0003]
However, when assembling the vehicle body or assembling the hatch gate, there may be variations in the size of the gap between the closed hatch gate and the vehicle body due to the effects of the accuracy of each part and the assembly accuracy. It is necessary to adjust the protrusion height of the stopper from the body side wall by arranging an appropriate thickness or number of shims, etc. between the body side wall and the stopper so that the above gap is constant when the hatch gate is closed. However, there is a problem that adjustment work for appropriately inserting and removing such shims for each vehicle requires a great number of man-hours and is very troublesome.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to enable easy adjustment of the size of a gap between a door and a vehicle body when the vehicle door is closed.
[0005]
[Means for Solving the Problems]
For this reason, a damper for a vehicle door according to the present invention includes a first damper member attached to a peripheral portion of a door opening in a vehicle body, and the first damper member attached to a door that opens and closes the door opening. 1 and a second damper member abuts against the damper member, and the first damper member and shim disposed between said peripheral portion, said shim, and the mounting surface to the periphery, the mounting surface and The vehicle body has a support surface that is inclined with respect to the front, rear, left, and right sides of the vehicle body and holds the first damper member, and is inserted into a long hole that is formed on either the mounting surface or the peripheral portion and extends in the direction of the inclination. The mounting surface is configured to be fixed to the peripheral edge by the fastening member.
[0006]
Therefore, when the relative protrusion height of the first damper member and the second damper member is not good when the door is closed, the shim is formed on either the mounting surface of the shim or the peripheral edge of the door opening. loosening the fastening member for inserting the long holes, by suitably displacing the shim along the long hole, the first damper member which is held on the support surface inclined relative to the mounting surface of the shim against the second damper member Therefore, the height can be easily adjusted so that the door is satisfactorily closed by the contact of the first damper member and the second damper member.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention shown in the drawings will be described.
[0008]
A door opening 2 is formed at the rear portion of the vehicle body 1, and hinges 5 are respectively attached between the left and right peripheral edge portions 3 of the door opening 2 and the tail gate 4. The tail gate 4 is rotated with respect to the vehicle body 1 by the hinge 5. The door opening 2 can be opened and closed, and first damper members 6 are respectively attached to the lower portions of the left and right peripheral edge portions 3 that are inclined in the vehicle longitudinal direction and the vertical direction. 7 is attached.
[0009]
The first damper member 6 is made of a slightly hard rubber, and has a flexible pleat 11 formed at the top of the central corner 10, and bolt holes 13 are provided on the mounting surfaces 12 on both sides of the corner 10. The second damper member 7 is made of a hard resin, has a central corner portion 14, and has bolt holes 16 on the mounting surfaces 15 on both sides of the corner portion 14. The second damper member 7 is attached to the tailgate 4 by inserting the bolt 17 through the bolt hole 16 and screwing it into the weld nut 18 on the tailgate 4 side.
[0010]
On the other hand, the press-formed shim 20 has a central support surface 21 inclined with respect to the attachment surfaces 22 on both sides of the support surface 21, and a long hole 23 extending in the inclination direction is provided on the attachment surface 22. The bolt 24 is inserted into the bolt hole 13 of the first damper member 6 and screwed into the weld nut 25 on the back surface of the support surface 21, whereby the first damper member 6 is fixed to the shim 20 and the screw 26 is attached to the shim. The shim 20 is fixed to the door opening peripheral portion 3 by being inserted into the long hole 23 of the surface 22 and screwed into the weld nut 27 on the door opening peripheral portion 3 side.
[0011]
Therefore, when the first damper member 6 is fixed to the door opening peripheral portion 3 via the shim 20 and the tailgate 4 closes the door opening 2 as shown in FIGS. The top of the central corner portion 10 of the damper member 6 and the top surface of the central corner portion 14 of the second damper member 7 elastically contact each other, and the central support surface 21 of the shim 20 has a vehicle width with respect to the mounting surface 22. It is supposed to tilt in the direction.
[0012]
That is, when the tailgate 4 is closed with respect to the door opening 2 when the vehicle is assembled, the gap between the tailgate 4 and the left and right peripheral edge portions 3 becomes too large or too small. Therefore, the central corner portion 10 of the first damper member 6 If the balance between the height at which the top protrudes from the left and right peripheral edge portions 3 and the height at which the top surface of the second damper member 7 protrudes from the tailgate 4 is poor, the screw 26 screwed into the weld nut 27 is slightly When the first damper member 6 and the shim 20 are slid appropriately along the elongated hole 23 of the shim mounting surface 22 in the direction of arrow A in FIGS. 3 and 4, the inclined central support surface 21 of the shim 20 is obtained. Since the 1st damper member 6 is attached to the 1st damper member 6, the height which the top part of the center corner | angular part 10 in the 1st damper member 6 protrudes to the 2nd damper member 7 can be adjusted easily. For this reason, the tailgate 4 with respect to the door opening 2 in a state where the top of the central corner 10 of the first damper member 6 and the top of the central corner 14 of the second damper member 7 are in contact with each other with an appropriate strength. Can be adjusted to close well.
[0013]
In this case, the adjustment of the gap may be performed by operating the screw 26 and the integral sliding of the first damper member 6 and the shim 20, and there is no complication of replacing the shim 20. There is a great advantage that can be accomplished in a short time.
[0014]
In the above embodiment, the shim is provided with a long hole extending in the inclination direction of the first damper member support surface. However, the long hole is provided on the door opening side of the vehicle body. In the example, the shim is integrated with the first damper member on the door opening side of the vehicle body. However, the shim is integrated with the second damper member on the tailgate side, and the second is formed along the long hole on the shim or tailgate side. Even if the damper member and the shim can be slid, it is possible to achieve the same effects as the above-described embodiment examples, and further, the present invention can be applied not only to the tailgate but also to a door such as a side door. Nor.
[0015]
【The invention's effect】
In the vehicle door damper according to the present invention, the fastening member that passes through the long hole formed on either the shim mounting surface or the peripheral edge of the door opening is loosened, and the shim is moved along the long hole. By appropriately displacing, the relative protrusion height of the first damper member and the second damper member is easily adjusted, and the door is satisfactorily closed by the contact of the first damper member and the second damper member. Therefore, the man-hours required for the door closing adjustment work can be greatly reduced as compared with the prior art.
