Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper structure for a slide door, and more particularly to an improvement of a stopper structure for suppressing an overrun when the door is closed to prevent interference between the closed end of the slide door and the closed end of the vehicle body opening. .

[0002]

2. Description of the Related Art Conventionally, cushion rubber has been used to suppress overrun due to inertia when a sliding door is closed. An example thereof is shown in FIG. In FIG. 8, a cushion rubber 6 is provided at an upper end portion of a closed end D1 (hereinafter referred to as a door closed end) of a slide door D that opens and closes a side opening O of a vehicle body. The cushion rubber 6 has a block-shaped rubber body 61 as shown in FIG.
It is installed toward a closed end O1 of the vehicle body opening O (hereinafter referred to as an opening closed end). A lip portion 62 is formed on the tip end surface of the rubber body 61 so that the lip portion 62 opens at the closed end O1 as shown in FIG. 9 when the slide door D is fully closed.
And is elastically deformed by being pressed into contact with the front pillar panel 4 constituting
The relatively weak reaction force suppresses the slide door D from moving back and forth (opening and closing direction). If the slide door D overruns forward (to the left in the figure) due to its inertia when closing the slide door D, the tip end surface of the rubber body 61 directly contacts the front pillar panel 4 and the rubber body 61 is elastic in the compression direction. Be transformed,
Due to the repulsive force, overrun is suppressed and interference between the door closing end D1 and the opening closing end O1 is prevented.

In order to prevent the sliding door D from swinging in and out of the vehicle while the vehicle is traveling, a down stopper 7 is provided at a vertical position at the door closing end D1 as shown in FIG. For example, as shown in FIG. 10, the down stopper 7 is provided with a stopper 71 having a convex portion 711 on the door closing end D1 side, while a recess 721 for receiving the convex portion 711 is formed on the opening closing end O1 side. Stopper tool 7
2 is provided, and when the slide door D is fully closed, the convex portion 7
By fitting 11 and the concave portion 721, the movement of the slide door D in the inward and outward directions is restricted, and the steady rest is achieved.

[0004]

By the way, when the clearance (L in FIG. 8) in the fully closed state of the door is reduced from the viewpoint of design, the amount of compressive deformation of the rubber body 61 when the slide door D overruns. In the same manner as in the conventional case, the door closing end D1 may interfere with the opening closing end O1. Therefore, in order to prevent this, measures such as increasing the hardness of the rubber main body 61 to improve its repulsive force, or increasing the number of cushion rubbers 6 installed to improve the repulsive force as a whole are taken. However, according to this, there is a possibility that the vehicle body opening edge panel 4 at the opening closed end O1 may be deformed due to the collision of the cushion rubber 6 having increased hardness, and it is difficult to add the cushion rubber 6 in a limited space. Often

Further, when it is desired to reduce the width of the pillar surface facing the opening of the front pillar of the vehicle body opening by design, there is a case where the installation space for the upper down stopper cannot be secured, and in this case, the sliding door swings. Preventive measures are also required.

The present invention solves such a problem by avoiding the deformation of the vehicle body panel at the opening closed end, while reliably preventing the interference between the door closing end and the opening closing end, and at the same time ensuring the door. An object of the present invention is to provide a stopper structure for a slide door that can prevent shake.

[0007]

To achieve the above object, in the first aspect of the present invention, the closed end (D) of the slide door (D) is used.
1) and a first stopper body (1) provided on one of the closed ends (O1) of the vehicle body opening (O) opened and closed by the slide door (D) and a second provided on the other of the both closed ends. The stopper body (2) is provided, and the first stopper body (1) has a first contact surface (1b) orthogonal to the moving direction of the slide door (D) and a moving direction of the slide door (D). The second stopper body (2) is provided with a second contact surface (1c) inclined with respect to the second contact surface (1c), and one of the both closed ends of the second stopper body (2) abuts when the slide door (D) is in the fully closed position. A possible first receiving portion (22), an elastically deformable second receiving portion (2a) with which the second contact surface (1c) approaches or abuts when the slide door is at the fully closed position, and a slide door ( When D) is in the fully closed position, it is separated from the first contact surface (1b) and slides. A (D) is a third receiving portion in which the first contact surface (1b) is elastically deformed in contact when moving the closing direction beyond the fully closed position (2b).

In the first aspect of the present invention, when the slide door is in the fully closed state, one of the closed ends abuts against the first receiving portion of the second stopper body to elastically deform the same, and at the same time the first stopper body moves. The second contact surface is close to or in contact with the second receiving portion of the second stopper body. In this state, the second receiving portion is not elastically deformed or is slightly deformed,
Only a weak reaction force is exerted on the slide door due to the elastic deformation of the first receiving portion, and this prevents the slide door from moving back and forth due to vibration or the like during traveling of the vehicle. In addition, since the second contact surface and the second receiving portion are close to or in contact with each other, the swing of the slide door in and out of the slide door due to vibration during traveling of the vehicle is restricted. When the sliding door is closed, if the inertia of the sliding door exceeds the fully closed position and overruns, the second contact surface of the first stopper body comes into contact with the second receiving portion of the second stopper body, and the second contact surface of the second stopper body is greatly elasticized. Transform it,
This causes a large reaction force that regulates overrun. When the overrun of the sliding door becomes large,
In response to this, the amount of elastic deformation of the second receiving portion increases and the reaction force increases, and further, the first contact surface of the first stopper body contacts the third receiving portion of the second stopper body and this The elastic deformation causes the reaction force to increase rapidly. As described above, according to the first aspect of the present invention, only a weak reaction force due to the elastic deformation of the first receiving surface acts on the longitudinal movement of the slide door due to the vibration or the like while the vehicle is traveling with the door fully closed. It is possible to suppress the longitudinal vibration of the sliding door while the vehicle is traveling, while keeping the door closing force required to close the sliding door small. Further, since the second contact surface and the second receiving portion are close to or in contact with each other, it is possible to reliably prevent the slide door in the fully closed state from swinging inward and outward. When the slide door overruns, the second contact surface of the first stopper body contacts the second receiving portion of the second stopper body, and the first contact surface of the first stopper body contacts the second stopper body. A large reaction force is generated by the elastic deformation of these receiving portions due to the contact with the third receiving portions, whereby excessive overrun can be suppressed and interference between the door closed end and the opening closed end can be reliably prevented. By appropriately setting the inclination angle of the second contact surface, it is possible to appropriately adjust the magnitude of the repulsive force generated according to the overrun amount of the slide door.

In the second aspect of the present invention, the first stopper body (1) is orthogonal to the moving direction of the slide door (D) and the first receiving portion (22) when the slide door (D) is at the fully closed position. ) And one of the closed ends (O1) is provided with a third contact surface (1a).

In the third aspect of the present invention, the first stopper body (1) has a columnar shape, the first contact surface (1b) is formed at the tip thereof, and the second contact surface (1b) is formed on the outer peripheral surface. 1
c) is formed, the second stopper body (2) has a container shape capable of receiving the first stopper body (1), and the first receiving portion (22) is formed at the opening edge thereof, The second receiving portion (2a) is formed on the inner peripheral surface, and the third receiving portion (2b) is formed on the inner bottom surface. In the third aspect of the present invention, the columnar first stopper body is received in the container-shaped second stopper body, so that the swing of the slide door in and out is more effectively restricted.

In the fourth aspect of the present invention, a flange portion (211) extending in a direction orthogonal to the moving direction of the slide door (D) is formed at the opening edge of the second stopper body (2). The first receiving portion (22) is formed on the surface of the flange portion (211) on the one (D1) side of both closed ends. In the fourth aspect of the present invention, the impact of the slide door at the time of overrun can be dispersed by the elastic deformation of the first receiving portion and the elastic deformation of the flange portion.

In the fifth aspect of the present invention, the second stopper body (2) has a metal core portion (21) and a rubber insert molding portion (23) insert-molded on the surface of the core portion (21). And the first receiving portion (2
2), the second receiving portion (2a), and the third receiving portion (2b)

1 is a front view of a sliding door having a stopper structure according to the present invention in a fully closed state. Figure 1
In the above, the slide door D has a known structure and is slidable in the vehicle front-rear direction (left-right direction in FIG. 1), and is slid forward in the vehicle (left-side in FIG. 1) to close the side opening O of the vehicle body. . At the lower end of the door closed end D1, the down stopper 7 already described in the prior art is provided. Further, stopper bodies 1 and 2 are provided at the upper ends of the door closing end D1 and the opening closing end O1 facing the door closing end D1. More specifically, the stopper body 1 provided at the door closed end D1 of the slide door D has a convex shape as a whole as shown in FIG. 2, and a stay 31 for supporting the upper roller 3 which guides the upper edge of the slide door D. It is installed at the base of. On the other hand, as shown in FIG. 3, the stopper body 2 provided at the opening closed end O1 is installed at the front upper corner portion of the vehicle body opening edge panel 4 which constitutes the opening closed end O1, and the stopper body 1 having the convex shape described above. The overall shape is concave to accommodate Then, as shown in FIG. 4, the slide door D
Is fully closed, stopper body 1

In FIG. 5, the stopper body 1 is an integrally molded product made of resin, and has a circular flange portion 11 located in contact with the plate surface of the stay 31 and a substantially columnar protrusion protruding from the center portion of the flange portion 11. The unit 12 is provided. Flange part 1
The plate surface of No. 1 is a plane shape orthogonal to the axis, that is, the moving direction of the slide door D when opening and closing, and constitutes the third contact surface 1a described in the claims. The central portion of the protrusion 12 is recessed, and a mounting hole penetrating the flange portion 11 is provided therein, and the bolt 5 inserted into the mounting hole.
The stopper body 1 is fixed to the stay 31 by 1. The tip end surface of the protrusion 12 is a flat surface orthogonal to the moving direction of the slide door D, and constitutes a first contact surface 1b described in the claims. Also, the protrusion 12
The outer peripheral surface of the tip side half portion is an inclined surface that is inclined from the base end toward the tip at a constant angle with respect to the moving direction of the slide door D, and is the second contact surface 1c described in the claims. Are configured.

The stopper body 2 is a circular container body that opens toward the stopper body 1, and a rubber material as an elastic material is injection-molded into a predetermined shape on the surface of an insert member 21 as a container-shaped core portion to insert it. It is a molding part 23. More specifically, the opening edge of the insert member 21 is curved outward and extends as the flange portion 211 in a direction orthogonal to the moving direction of the slide door D, and the insert molding portion 23 formed on the surface thereof. A part of the flange part 211 projects as a thin wall around the entire circumference of the flange part 211 to form a lip part 22 as a first receiving part. On the other hand, the insert molding portion 23 formed on the inner circumference of the insert member 21 is an inclined surface that is inclined along the second contact surface 1c of the stopper body protruding portion 12 in the entire peripheral region near the opening. Is the second receiving portion 2a described in the range. In addition, the insert molding portion 23 has a stepwise inward thick wall over the entire circumference of the inner peripheral intermediate position adjacent to the second receiving portion 2a, and is orthogonal to the moving direction of the slide door D here. , A flat surface having a predetermined width is formed, and the third aspect described in the claims.
It constitutes the receiving surface 2b. The insert-molded portion 23 is thin and recessed in the center of the insert member 21, and a mounting hole is provided in this portion, and the stopper body 2 causes the stopper body 2 to be opened by the bolt 52 inserted into the mounting hole. It is fixed to. The insert molding part 23
Is an extension portion 231 that extends from the front surface side to the back surface side of the insert member 21 with a predetermined thickness to prevent the insert molding portion 23 from peeling off from the insert member 21. ing.

In such a stopper structure, when the slide door D is in the normal fully closed position, as shown in FIG.
As shown in FIG. 3, the third contact surface 1a of the stopper body 1 is pressed against the lip portion 22 of the stopper body 2 to elastically deform it. In this state, the second contact surface 1c of the stopper body 1 is in contact with the second receiving portion 2a of the stopper body 2 without being proximately or substantially deformed, and the first contact surface 1b of the stopper body 1 is in contact. And the third receiving portion 2b of the stopper body 2 are spaced apart from each other. Therefore, only a weak reaction force due to the elastic deformation of the lip portion 22 acts on the slide door D, which suppresses the forward / backward movement of the slide door D due to vibration or the like during traveling of the vehicle. In addition, since the second contact surface 1c and the second receiving portion 2a are close to or in contact with each other, the down stopper is not provided at the upper end portion of the door closed end D1 (FIG. 1), the vehicle according to the present embodiment as well. The swinging of the slide door D in the inward and outward directions due to vibrations during traveling is effectively restricted.

When the slide door D is closed, if its inertia causes an overrun beyond the normal fully closed position,
As shown in FIG. 6B, in addition to the deformation of the lip portion 22, the second contact surface 1c of the stopper body 1 abuts on the second receiving portion 2a of the stopper body 2 and elastically deforms it. This causes a large reaction force that regulates overrun.
When the amount of overrun of the slide door D increases, the amount of elastic deformation of the second receiving portion 2a correspondingly increases and the above reaction force increases, and further, the first contact surface 1b of the stopper body 1 moves to the stopper body 2. Abut the third receiving portion 2b (see FIG. 6).
(B)) This is elastically deformed, so that the reaction force rapidly increases.

In FIG. 7, the third contact surface 1a of the stopper body 1 on the slide door D side comes into contact with the lip portion 22 of the stopper body 2 on the vehicle body side, reaches the regular fully closed position, and further overruns. The relationship between the movement amount of the slide door D and the reaction force generated by the stopper bodies 1 and 2 at this time is shown (solid line in FIG. 7). When the amount of overrun increases, the reaction force abruptly increases due to the elastic deformation of the second receiving portion 2a and the third receiving portion 2b, and further overrun of the slide door D is restricted, and the door closing end D1 (FIG. 1) and the opening are opened. The interference of the closed end O1 is prevented in advance. At this time, while the amount of overrun is small, the reaction force is also small, so that the impact of the slide door is absorbed and relaxed satisfactorily.

On the other hand, in the stopper structure using the rubber cushion described in the prior art, even if the sliding door overruns, the reaction force of the stopper structure does not increase so much (broken line in FIG. 7), so that the door closed end It is not possible to effectively prevent interference at the closed end of the opening. When the hardness of the rubber cushion is increased, a slight overrun of the slide door causes an excessive reaction force (chain line in FIG. 7). Therefore, a slight front-back movement of the slide door caused by vibration while the vehicle is running causes a large impact, resulting in a large body panel. May be deformed.

In the above embodiment, the first stopper body is provided at the closed end of the slide door and the second stopper body is provided at the closed end of the vehicle body opening, but this may be reversed.

[0025]

As described above, according to the stopper structure for a sliding door of the present invention, the interference between the door closing end and the opening closing end is surely prevented while avoiding the deformation of the vehicle body panel at the opening closing end. At the same time, it is possible to reliably prevent the door from swinging.
