Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wedge structure for a sliding door for a vehicle.

(Prior art) Generally, in vehicles such as wagon type cars,
As shown in Fig. 1, a sliding door opening 2 is provided on the side of the vehicle body 1, and a sliding door 3 is attached to the opening 2 so as to be able to slide rearward, allowing passengers to get in and out of the vehicle and luggage to be taken in and out. It is designed so that it can be easily carried out. In addition, 4 is a front door, 5 is a center pillar, and 6 is a slide rail.

In such vehicles, conventionally, in order to absorb the impact force when the sliding door 3 is closed,
A mail 7 made of hard rubber or synthetic resin as shown in FIG. A wedge structure is provided in which a metal or synthetic resin sleeve 8 that removably fits into the mail 7 is fixed on the other side, so that the mail 7 and the sleeve 8 fit together when the sliding door 3 is closed. It is taken.

(Problems to be solved by the invention) However, in the above conventional wedge structure,
Since mail 7 and Himer 8 are both made of hard materials, it is not possible to ensure sufficient shock absorption.
Therefore, when the sliding door 3 is strongly closed, the impact force is not absorbed but is directly transmitted to the center pillar 5, the front door 4, etc., resulting in damage to these members 5, 4.

Therefore, conventionally, in order to deal with this problem, reinforcing plates were welded to the center pillar 5, front door 4, etc. to strengthen them more than necessary and increase their rigidity. This method has the drawbacks of increasing the number of parts and man-hours, resulting in higher costs and weight.

Further, for this reason, even if the mail and the Himale are simply formed of a soft material, if the spring constant is constant, the following problem will occur.

For example, if the spring constant is set to a relatively large value, when the sliding door is closed, the mail and the sliding door will come into contact and the impact force will be absorbed, but on the other hand, the sliding door will bounce back due to the large reaction force. The drawback is that it cannot be closed completely. On the other hand, if the spring constant is set to a small value, although there is no problem with the sliding door bouncing back as described above, the impact force is not sufficiently absorbed and is transmitted to the front door, etc., making it difficult to prevent damage to the front door, etc. In addition, when the sliding door is in the closed state, it is not possible to obtain sufficient holding force against lateral vibration of the sliding door, and as a result, the sliding door may be sucked out when the vehicle is running, or the sliding door may be sucked out due to vibrations of the vehicle body. The drawback is that the sliding door may vibrate and make abnormal noises.

The present invention has been made in view of this point, and when the sliding door is closed, when the mail and the Himail come into contact with each other, the spring constant for the load in the front and back direction is changed between the initial stage and the latter stage, and the sliding By effectively absorbing the impact force when the sliding door is closed without causing the door to rebound, and by ensuring the holding force against the sliding door's lateral vibration when the mail and the Himeru are engaged, the sliding door can be closed easily. The purpose is to prevent damage to the front door etc. due to the impact of time, and to ensure a good closing condition of the sliding door.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention provides a means for solving the problem by attaching the The object of the present invention is a wedge structure of a sliding door for a vehicle, which is composed of a fixed mail and a thin mail fixed to the other side, and the mail and thin mail fit together when the sliding door is closed. and,
The above-mentioned mail has a structure in which the spring constant against the load in the longitudinal direction is small in the initial load region when the sliding door is closed, and becomes large in the latter stage load region, and the spring constant in the left-right direction when the mail and the Himer are fitted is This is a configuration in which the value becomes large.

(Function) With the above configuration, in the present invention, when the mail and the female fit together when the sliding door is closed, the spring constant for the load in the front and back direction is small in the initial load area, so that the initial load when the sliding door is closed is It easily deforms elastically against a large impact force, absorbs and alleviates this impact force, and reduces it to a small amount.
After that, in the latter stage of the load region when the impact force is reduced to a small level, the spring constant against the load in the longitudinal direction is large, so this small impact is completely absorbed without causing the sliding door to rebound. Therefore, the impact force when the sliding door is closed is effectively absorbed without causing the sliding door to bounce back or the impact force to be transmitted to the front door, etc., and the mail and the female can be fitted together.

Moreover, in the fitted state of the above-mentioned mail and Himale, the spring constant in the left and right direction is large, so that a sufficient holding force against lateral vibration of the sliding door is ensured, and a tight fitting state between the two is maintained. become.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. Incidentally, since the basic structure of the vehicle sliding door has already been described with reference to FIG. 1, the same parts are given the same reference numerals and detailed explanation thereof will be omitted.

FIGS. 3 and 4 show a first embodiment of the present invention, and reference numeral 9 is a hinge fixed to the front edge of the sliding door 3, and the hinge 9 is made of synthetic resin or metal, and the center of the surface thereof is A fitting recess 10 having a substantially semicircular cross section is formed to removably fit a mail 12 to be described later, and bolt holes 11 for fixing to the sliding door 3 are provided at the upper and lower ends of the fitting recess 10. 11 are drilled. Also, 12
is a mail fixed to the side edge of the sliding door opening 2 of the vehicle body 1 facing the above-mentioned armature 9, and the mail 12 and the armature 9 are provided so as to fit together when the sliding door 3 is closed. .

The mail 12 is made up of a metal base body 13 in the shape of a substantially rectangular plate and a fitting body 14 fixed to the base body 13, and the upper and lower ends of the base body 13 are for fixing to the sliding door opening 2. bolt hole 1
5 and 15 are drilled. The above-mentioned fitted body 14 is
It is made of an elastic body such as soft rubber that is integrally formed with a base 14a having a substantially triangular cross-sectional shape and a lip 14b extending rearward on both sides from the top of the base 14a, and has a spring constant against the load in the front and back direction when the sliding door 3 is closed. The spring constant is small in the initial load area, becomes large in the late load area, and becomes large in the left-right direction when the fitter 8 is fitted into the fitting recess 10.

Next, the operation of the above embodiment will be explained.
When the mail 12 and the female mail 9 fit together when the sliding door 3 is closed, in the initial load region, the mail 12 abuts the fitting recess 10 of the female mail 9 at the lip portion 14b of the fitting body 14, and Since the lip portion 14b is immediately bent inward by the pressing force from the fitting recess 10, the spring constant against the load in the longitudinal direction of the mail 12 is small. Then, when the fitting body lip portion 14b is completely bent inward and the inner surface thereof comes into contact with the side surface of the base 14a of the fitting body 14 in the latter stage load region, the entire fitting body 14 is subjected to the pressing force from the female fitting recess 10. Therefore, the spring constant for the load in the longitudinal direction of the mail 12 increases. In this way, the spring constant for the load in the longitudinal direction of the mail 12 is such that the stroke increases exponentially as the load increases, as shown in Figure 5, and becomes small in the initial load region and large in the late load region. . Therefore, even with a small spring constant, the initial large impact force when the sliding door 3 is closed is smoothly absorbed and alleviated without causing rebound, and the later small impact force that is reduced due to this absorption and relaxation is reduced by a large spring. Even at a constant value, absorption and relaxation occur completely. In other words, the spring constant of the mail 12 that is adapted to the magnitude of the impact force allows the impact force to be absorbed step by step and smoothly without causing the sliding door to rebound or the impact force to be transmitted to the front door. become. Therefore, the impact force when the sliding door 3 is closed can be effectively absorbed by the elastic deformation of the mail 12, and the mail 12 and the female mail 9 can be reliably fitted.

Moreover, when the mail 12 and the female mail 9 are in the fitted state, the fitting lip portion 14b of the mail 12 that is bent inward tends to return to its original state.
The spring constant in the left and right direction becomes large. Therefore, the mail 12 and the female mail 9 are fitted in a tight state, and the holding force against lateral vibration of the sliding door 3 is strong, so that the sealing performance of the sliding door 3 can be improved, and the sliding door 3 can be damaged by wind when traveling. It is possible to prevent a suction phenomenon and the like, and to reduce vibrations of the sliding door 3 due to vibrations of the vehicle body.

Furthermore, as mentioned above, by effectively alleviating the impact force when the door is closed, the load applied to the sliding door side is reduced, so the wedge structure can be used even on the upper part of the sliding door (the sash part of the door), which was previously difficult to install. This is advantageous in terms of sealing performance of the sliding door 3 and prevention of the suction phenomenon.

6 and 7 show a second embodiment of the present invention, in which a mail 16 that fits into a female mail 9 is slid against a base body 17 having a substantially U-shaped cross section in the front and back direction. A movably supported fitting body 18 made of synthetic resin or hard rubber, and the fitting body 1
8 in the protruding direction. In this case, the spring constant for the load in the longitudinal direction of the mail 16 is as small as the spring constant of the spring member 19 in the initial load region, as shown in FIG. Since the values are the same and larger, the impact force when the sliding door 3 is closed can be effectively absorbed as in the case of the first embodiment. In addition, 20 is a presser metal fitting attached to the upper part of the base body 17.

In each of the above embodiments, the mailer 9 was fixed to the front edge of the sliding door 3, and the mailers 12 and 16 were fixed to the side edge of the sliding door opening 2 of the vehicle body 1.
On the contrary, the mail 12, 1 is attached to the front edge of the sliding door 3.
6 may be fixed, and the Himale 9 may of course be fixed to the side edge of the sliding door opening 2 of the vehicle body 1.

(Effects of the Invention) As explained above, according to the present invention, the mail is fixed to either the front edge of the sliding door or the side edge of the sliding door opening of the vehicle body facing the front edge, and the mail is fixed to the other side. In the wedge structure of a sliding door for a vehicle, the mail has a spring constant against the load in the longitudinal direction of the sliding door when the sliding door is closed. The structure is such that the spring constant is small in the initial load range and large in the late load range, and the spring constant in the left and right direction becomes large when the mail and Himale are fitted, so that the impact force when the sliding door is closed is reduced. It is possible to effectively absorb the rebound of the door without causing it, reliably prevent damage to the front door, etc., maintain the sliding door in a good closed state, and improve the sealing properties of the sliding door. This makes it possible to both improve the vehicle speed and reduce the vibration of the sliding door during driving. Furthermore, since a mail or a female mail can be attached to the upper part of the sliding door, there is an advantage that the sealing performance can be further improved and the vibration of the sliding door can be further reduced.
