Description

The present invention relates to the structure of a down stopper for a sliding door.

In the sliding door provided in the automobile, the side end of the roof on the upper part of the car body and the rail provided in the rocker part on the lower part of the car body are slidably hooked by the flanges with rollers fixed to the upper and lower parts of the sliding door. There is. However, a down stopper is provided to prevent the sliding door and the pillar from shaking relative to each other when the door is closed.

The down stopper is a convex or concave member provided on the opposite surface of the slide door and the pillar, and the material is hard rubber, resin or metal. When the sliding door is closed, these members are fitted to prevent the sliding door and the pillar from swinging relative to each other. Hereinafter, the convex member will be referred to as "mail", and the concave member will be referred to as "female".

The mail and female are arranged so as to fit on the opposing surfaces of the sliding door and the pillar when the door is closed. However, if the closing position of the sliding door shifts or the mounting position of mail and female shifts, strong interference may occur. As an adverse effect of strong interference, abnormal noise is generated. The mounting positions of the mail and the female are the mounting angle and the distance between the surfaces.

Patent Document 1 discloses a sliding door stopper structure that solves this problem. In Patent Document 1, the female hole has a cross-sectional shape in which the opening edge side is widened and narrows toward the back, and the protruding portion of the mail has a cross-sectional shape in which the tip is narrow and wide toward the root. There is. With such a shape, fitting is possible even if the opposite positions of the mail and the female are displaced.

However, in the case of Patent Document 1, if the surface distance between the sliding door and the pillar is deviated and the distance between the mail and the female mounting surface is increased, the mating of the mail and the female becomes insufficient. In such a case, as shown in Patent Document 2, by making the opening cross section of the female and the protruding cross section of the mail straight, there is no gap even if the surfaces are dispersed.

If the convex portion of the mail and the concave portion of the female are made straight in cross section as in Patent Document 2, there is no gap between the mail and the female with respect to the deviation of the surface distance between the sliding door and the pillar. However, if the mounting positions of the mail and the female (or the facing positional relationship between the sliding door and the pillar) deviate, strong interference will occur.

The present invention has been conceived in view of the above problems, and provides a slide door down stopper structure capable of simultaneously absorbing variations in mounting positions of mail and female and variations in surface spacing between sliding doors and pillars. Is.

More specifically, the down stopper structure of the sliding door according to the present invention is
A protruding root portion is formed on the base portion and the base portion, and a mail fixed to the pillar surface at the base portion and a concave member recessed from the opening toward the back portion are arranged on the sliding door surface. It is a down stopper structure of the sliding door that fits the female
At the root portion between the tip of the mail and the base portion, the outer peripheral wall spacing is larger than the joint portion between the base portion and the root portion, and the outer peripheral wall spacing is larger than the tip portion of the root portion. A contact with the female is formed,
When the Female and the mail is fitted, and wherein the inner peripheral wall spacing of the Female than the contact portion straight rear side is larger than the outer peripheral wall spacing of the mail straight outside of the contact portion ..

The down stopper structure of the sliding door according to the present invention does not plan to fit the entire surfaces of the outer wall surface of the mail and the inner wall surface of the female, but the contact portion between the mail and the female is outside the mail. It is formed in the area of either a part of the wall surface and the inner wall surface of the female. That is, one contactable area is wider than the other contactable area. Therefore, even if the attachment positions of the female and the mail are different, the contact portion is a narrow area, so that strong interference does not occur and the generation of abnormal noise can be prevented.

Further, since the other contactable area is wide, the contact portion is formed in a wide range. As a result, even if the surface distance between the pillar and the sliding door varies, the mating does not come off.

It is a figure which shows the position where the slide door stopper which concerns on this invention is arranged. It is sectional drawing of the slide door stopper part. The state in which the mating of FIG. 2 is released is shown. It is a figure which shows the effect of the slide door stopper which concerns on this invention by the deviation of a mounting position, and the deviation of a surface spacing. It is a figure which shows the modification of the sliding door stopper when the narrow contact area is provided on the female side. It is a figure which shows the modification of the slide door stopper when the narrow contact area is provided on the mail side. It is a figure which shows the modification of the sliding door stopper when the narrow contact area is staggered.

The down stopper structure of the sliding door according to the present invention will be described below with reference to the drawings. The following description exemplifies one embodiment of the present invention, and the present invention is not limited to the following description. Therefore, the following description can be modified without departing from the spirit of the present invention. In the present specification, the arrow Fr indicates the vehicle body front direction, and the arrow Rr indicates the vehicle body rear direction.

FIG. 1A shows the appearance of an automobile having a sliding door. The sliding door 10 is opened and closed by sliding in the front-rear direction with respect to the vehicle body. A down stopper 18 of the slide door 10 is attached to the region 11 where the facing surfaces of the slide door 10 and the pillar 12 are formed. For example, here, it is assumed that the down stopper 18 is attached to the region 13.

With reference to FIG. 1B, in the down stopper 18, the oval-shaped mail 20 and female 30 are arranged on the sliding door 10 and the pillar 12, respectively. It should be noted that which of the mail 20 and the female 30 is attached to the slide door 10 side and the pillar 12 side is not particularly limited. In this specification, the description will be continued with the female 30 arranged on the sliding door 10 side and the mail 20 arranged on the pillar 12 side. The length of the mail 20 of the down stopper 18 is set to the outer wall length of 20L.

The AA cross section of FIG. 1 (b) is shown in FIG. Note that FIG. 2 also shows the slide door 10 and the pillar 12 to which the down stopper 18 (see FIG. 1B) is attached. The facing surfaces of the slide door 10 and the pillar 12 are the slide door surface 10a and the pillar surface 12a, respectively.

With reference to FIG. 2, the down stopper 18 is a slide door in which the mail 20 which is a convex member installed on the pillar 12 is fitted with the female 30 which is a concave member installed on the slide door 10 side. The relative shaking of the 10 and the pillar 12 is prevented.

First, each part of the mail 20 and the female 30 will be described. FIG. 3 shows a cross-sectional view of the mail 20 and the female 30 in a disengaged state. The female 30 is a concave member recessed from the opening 30a toward the inner portion 30b. The female 30 is arranged on the sliding door surface 10a.

Here, the "back portion 30b" means a concave bottom when viewed from the opening 30a. The inner portion 30b does not have to be the same material as the female 30. This is because when the female 30 is formed only of the ring-shaped rubber material, the inner portion 30b becomes the sliding door surface 10a.

Further, in the inner peripheral wall 30w of the female 30, the distance between the inner peripheral walls 30w facing each other is defined as the inner peripheral wall spacing 31. The inner peripheral wall spacing 31 is a so-called gap. Further, the edge of the opening 30a is defined as the opening edge 30ae.

On the other hand, the mail 20 is a convex member having protrusions formed on the base portion 20b. It is fixed to the pillar surface 12a by the base portion 20b. The tip of the mail 20 is the tip 20a. The protrusion-shaped portion from the tip portion 20a to the base portion 20b is referred to as the root portion 20r.

Further, in the outer peripheral wall 20w of the mail 20, the distance between the outer peripheral walls 20w facing each other is defined as the outer peripheral wall spacing 21. The outer wall spacing 21 is the so-called "thickness" of the mail 20. Further, as already described, in the mail 20 having an oval shape as a whole, the length of the mail 20 is referred to as an outer wall length 20L (see FIG. 1B).

Further, in the mail 20 and the female 30, the planned contact area means an area scheduled to come into contact with the partner member. It may be called a contactable area. The planned contact area can be determined by the dimensions of the mail 20 and the female 30.

In FIG. 3, in the female 30, the inner peripheral wall spacing 31 becomes wider from the opening edge 30ae toward the inner portion 30b after passing the shortest spacing point 32 where the inner peripheral wall spacing 31 becomes narrowest. Become. The inner peripheral wall spacing 31 at the shortest spacing point 32 is defined as the shortest inner peripheral wall spacing 31a.

In the female 30 in FIG. 3, the planned contact area is the shortest interval point 32. As will be described later, in the configuration of FIG. 3, the planned contact area of the female 30 is narrower than the planned contact area of the mail 20. Therefore, in FIG. 3 (and FIG. 2), the planned contact area of the female 30 is referred to as a narrow planned contact area 45n.

On the other hand, in the mail 20, the outer peripheral wall spacing 21 of the root portion 20r is formed to be constant, and the tip portion 20a has a tapered shape. The tapered shape is a shape in which the outer peripheral wall spacing 21 becomes thinner toward the apex of the mail 20. In this mail 20, the planned contact area is the root portion 20r. Since this is wider than the narrow scheduled contact area 45n of the female 30, it is called a wide scheduled contact area 45w.

As described above, in the down stopper structure 1 according to the present invention, a narrow scheduled contact area 45n is formed on one of the mail 20 and the female 30, and a wide scheduled contact area 45w is formed on the other side. As will be described later, the narrow scheduled contact area 45n and the wide scheduled contact area 45w can be formed in both the mail 20 and the female 30.

See FIG. 2 again. In the state where the down stopper 18 described with reference to FIG. 3 is fitted, the contact portion 40 is the shortest interval point 32 of the female 30. The mail 20 and the female 30 have a structure in which contact is not scheduled except for the contact portion 40. FIG. 2B shows a partially enlarged view of FIG. 2A. FIG. 2B shows the shortest inner peripheral wall spacing 31a at the shortest spacing point 32 (contact portion 40) of the female 30 and the inner peripheral wall of the female 30 on the inner side 30b (see FIG. 3) side of the contact portion 40. The interval 31 and the outer peripheral wall interval 21 of the mail 20 outside the contact portion 40 are shown.

Here, the inner peripheral wall spacing 31 on the inner peripheral wall 30b side of the contact portion 40 is wider than the outer peripheral wall spacing 21 outside the contact portion 40. More specifically, the outer peripheral wall spacing 21 of the mail 20 on the inner side 30b side of the contact portion 40 is narrower than the inner peripheral wall spacing 31 of the inner peripheral wall 30w of the opposing female 30. That is, the mail 20 is fitted so as to be picked in the narrow gap of the female 30.

Even if the mounting positions of the mail 20 and the female 30 are slightly different from each other with respect to the sliding door surface 10a and the pillar surface 12a, which are facing surfaces, the female 30 can guide the mail 20 to the center of the recess. , Fit.

FIG. 4A shows this situation. Since the mail 20 is attached to the pillar surface 12a so as to be displaced upward from the normal position in the drawing, the interference portion 50 is generated when the mail 20 is fitted with the female 30. However, since the contact portion 40 is a limited region in the inner peripheral wall 30w of the female 30, it is possible to overcome the interference and form a fitted state. At this time, almost no abnormal noise is generated.

Further, even when the surface distance 11L between the slide door surface 10a and the pillar surface 12a is deviated (separated), the wide contact area 45w in the mail 20 extends to the root portion 20r, so that the contact portion 40 If the root portion 20r is inserted up to the inner portion 30b side, the mail 20 can form a fitted state with the female 30 regardless of the insertion depth of the mail 20.

FIG. 4B shows this situation. The sliding door surface 10a and the pillar surface 12a are within the specified range when the sliding door 10 is closed, but stop slightly wider. Therefore, the amount of the mail 20 inserted into the female 30 is shallower than that in the case of FIG. However, the contact portion 40 of the female 30 comes into contact with the root portion 20r of the mail 20, and the fitted state can be maintained.

In the down stopper structure 1 according to the present invention, when the mail 20 and the female 30 are fitted, the inner peripheral wall spacing 31 of the female 30 on the immediate back side of the contact portion 40 is the mail 20 immediately outside the contact portion 40. The structure is not limited to the above as long as it can be formed so as to be larger than the outer peripheral wall spacing 21 of the above.

FIG. 5A shows a case where the contact portion 40 is provided closer to the inner portion 30b of the female 30. Further, FIG. 5B shows a case where the concave shape of the female 30 is a straight hole shape as a whole, and a convex contact portion 40 is provided in the middle.

6 (a), (b), and (c) show the case where a portion where the outer peripheral wall spacing 21 becomes large is formed at the root portion 20r on the mail 20 side. In this way, the contact portion 40 not only creates a portion where the inner peripheral wall spacing 31 is narrow on the inner peripheral wall 30w of the female 30, but also creates a thick portion of the outer peripheral wall spacing 21 at the root portion 20r (convex shape) of the mail 20. You may.

Even in the case of the modified examples as shown in FIGS. 5 and 6, when the mail 20 and the female 30 are fitted, the inner peripheral wall spacing 31 of the female 30 immediately behind the contact portion 40 is the contact portion. It is larger than the outer peripheral wall spacing 21 of the mail 20 immediately outside the 40. In either case, as in the example shown in FIG. 2, no abnormal noise is generated due to the deviation of the mounting position, and even if the surface distance 11L between the sliding door surface 10a and the pillar surface 12a deviates, the mail 20 And the female 30 can be established.

It is sufficient that such a contact portion 40 is partially formed over the outer wall length 20L of the mail 20. Further, it may be formed at a plurality of points discretely.

FIG. 7 shows an example thereof. FIG. 7A is a side view of the mail 20, and FIG. 7B is a bottom view. In the mail 20, a narrow contact area 45n is arranged in a staggered pattern. Even in such a case, abnormal noise is hardly generated due to the deviation of the mounting position, and even if the surface distance 11L between the sliding door surface 10a and the pillar surface 12a deviates, the mating state of the mail 20 and the female 30 is established. be able to. Further, a narrow planned contact area 45n may be provided on the female 30 side in a staggered arrangement.

The down stopper structure according to the present invention can be suitably used as a down stopper structure for a sliding door.
