JP 2018-103909 A

By the way, the down stopper is set so that when the sliding door is closed, the stopper on the side of the sliding door is pressed against the stopper on the side of the vehicle body to stabilize the sliding door.

However, depending on manufacturing errors or mounting accuracy of the sliding door or vehicle body, a minute gap or lack of pressure contact force may occur between the concave and convex portions, and the parts sandwiching the gap may repeatedly collide with vibrations during vehicle travel. may cause abnormal noise.

On the other hand, it is conceivable to increase the pressure contact amount between the stoppers to such an extent that it is possible to sufficiently prevent the gap from being formed between the concave portion and the convex portion. , the durability and wear resistance of the down stopper may be reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle structure that can prevent the occurrence of abnormal noise with a simple and inexpensive structure without pressing a fitting member between a slide door and a vehicle body.

In order to achieve the above object, the vehicle structure according to the present invention provides a sliding door provided on the side of a vehicle body, and a fitting member paired with a portion of the vehicle body that faces the sliding door when the door is closed. are provided, and the pair of fitting members are formed with recesses and protrusions that can be fitted to each other, and the recesses and protrusions are provided in the direction of separating or contacting them when they are fitted. Magnetism is imparted.

As described above, according to the present invention, magnetism is imparted to the recesses and projections of the paired fitting members provided on the sliding door and the vehicle body. can be kept either in contact or apart by As a result, even if a minute gap is formed between the concave portion and the convex portion of the fitting member, collision between the concave portion and the convex portion due to vibration during vehicle running can be prevented or alleviated, and the fitting member can be prevented from colliding with each other. Abnormal noise can be prevented with a simple and inexpensive structure without pressure contact.

Magnetism can be imparted to four surfaces, for example, both inner surfaces of the concave portion and both outer surfaces of the convex portion that fits inside the concave portion. applied to keep the recesses and protrusions spaced apart. In this case, in addition to preventing collision between the concave portion and the convex portion, it is possible to prevent the contact between the concave portion and the convex portion, thereby improving the durability and wear resistance of the fitting member.

In addition, by imparting magnetism that produces a repulsive force to one pair of the inner surface of the recess and the outer surface of the protrusion, and imparting magnetism that produces an attracting force to the other pair of the inner surface of the recess and the outer surface of the protrusion, The convex portion can be kept in contact with the suction side. In this case, the combination of the repulsive force and the attractive force can effectively bring the concave portion and the convex portion into contact with each other and maintain the contact state.

In addition, by imparting magnetism to the concave and convex portions by means of an electromagnet, magnetism can be imparted only while the vehicle is running. The opening and closing operability of the can be improved.

EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the vehicle structure which concerns on this invention is demonstrated using drawing.

As shown in FIGS. 1-3, the vehicle structure 1 according to the present invention includes a sliding door 3 provided on the rear side of a vehicle body 2, and a center door facing the front end of the sliding door 3 when the door of the vehicle body 2 is closed. The pillar 4 is provided with a down stopper 5 as a paired fitting member, and the down stopper 5 is formed with a concave portion 6 and a convex portion 7 that can be fitted to each other, and the concave portion 6 and the convex portion are formed. 7 is imparted with magnetism in the direction of separating or contacting them when they are fitted.

The sliding door 3 is arranged on the side of the vehicle body 2 and rearward of the center pillar 4, and is attached so as to be slidable in the front-rear direction with respect to the vehicle body 2, and its front end faces the center pillar 4 when the door is closed. It has become.

The center pillar 4 is formed near the center in the longitudinal direction of the side portions of the vehicle body 2 so as to connect the ceiling side and the floor side of the vehicle body 2, and a front door 8 is arranged in front of the center pillar 4. It is

The down stopper 5 includes a female down stopper 10 formed by forming an elongated concave portion 6 in a base plate 9 having a mounting hole 9a, and a protruding portion 7 formed in a base plate 11 having a mounting hole 11a. and a mail down stopper 12.

The female down stopper 10 is attached to the front end of the slide door 3 at two upper and lower locations, and the female down stopper 12 is aligned with the female down stopper 10 in the vertical and horizontal directions, and is positioned at the rear end of the center pillar 4. can be attached to By closing the slide door 3, the convex portion 7 of the male down stopper 12 enters and fits into the concave portion 6 of the female down stopper 10.例文帳に追加

The recessed portion 6 has a minimum width at a position slightly intruded from the opening edge, and the inner surface is set to a gently sloping surface so that the width becomes wider as it intrudes deeper from there, and the minimum width is set to be larger than that of the convex portion 7. For example, it is set larger by about 0.2 mm. Magnets 13 and 14 are embedded in the concave portion 6 with their end surfaces aligned with both inner surfaces of the portion having the minimum width, and the concave portion 6 is provided with magnetism.

The convex portion 7 is set to have a constant width along its projecting direction. Magnets 15 are embedded in the projecting portion 7 so that both end faces are aligned with both outer surfaces of a portion facing the magnets 13 and 14 when fitted into the recessed portion 6 , so that the projecting portion 7 is magnetized.

As shown in FIG. 3 , the magnets 13 and 14 of the concave portion 6 and the magnet 15 of the convex portion 7 are fitted together so that the S pole of the magnet 13 faces the S pole of the magnet 15 and the N pole of the magnet 15 faces the N pole of the magnet 15 . The north poles of the magnets 14 are set to face each other.

According to the above configuration, the magnets 13 and 14 are embedded in the concave portion 6 of the female down stopper 10 provided on the slide door 3, the magnet 15 is embedded in the convex portion 7 of the female down stopper 12 provided on the center pillar 4, Since the S and N poles of the magnets 13 and 14 are opposed to the S and N poles of the magnet 15, respectively, the concave portion 6 and the convex portion 7 can be kept apart by the repulsive force of the magnetic force when the door is closed. .

As a result, the concave portion 6 and the convex portion 7 of the down stopper 5 are not brought into pressure contact with each other, and a minute gap of, for example, about 0.1 mm is formed between the two, while the concave portion 6 and the convex portion 7 are displaced due to vibration during vehicle running. It is possible to suppress the momentum of the collision with, suppress the hammering sound to an inaudible level, and prevent the occurrence of abnormal noise. Moreover, contact itself between the concave portion 6 and the convex portion 7 can be prevented, and the durability and wear resistance of the down stopper 5 can be improved.

The strength of the repulsive force is set to 633 N, for example, when the gap between the magnets 13, 14 and 15 is 0.1 mm, the magnetic flux density of the magnets 13, 14 and 15 is 200 mT, and the end face is 5 mm x 10 mm. However, by changing and adjusting the magnetic force while checking the actual machine, it is possible to cope with cases where an abnormally large input is assumed.

It should be noted that the present invention is not limited to the above-described embodiments, and modifications can be made as appropriate within the scope of the present invention. For example, by imparting magnetism to the concave portion 6 and the convex portion 7 by an electromagnet, the magnetism may be imparted only while the vehicle is running. The opening/closing operability of the slide door 3 can be prevented from being impaired, and the opening/closing operability of the slide door 3 can be improved while preventing the collision between the concave portion 6 and the convex portion 7 due to vibrations during vehicle travel.

4, the magnets 13 and 14 of the concave portion 6 and the magnet 15 of the convex portion 7 are fitted together so that the S pole of the magnet 15 faces the S pole of the magnet 13 and the N pole of the magnet 15 is aligned. The S pole of the magnet 14 may be opposed to the pole.

In this case, when the door is closed, the repulsive force of the magnets 13 and 15 and the attractive force of the magnets 14 and 15 keep the side of the concave portion 6 on which the magnet 14 is provided and the convex portion 7 in contact with each other. Therefore, it is possible to prevent the collision between the concave portion 6 and the convex portion 7 due to the vibration during running of the vehicle, thereby preventing the occurrence of abnormal noise.

Further, instead of attaching the female down stopper 10 to the slide door 3 and attaching the female down stopper 12 to the vehicle body 2, the female down stopper 12 is attached to the slide door 3 and the female down stopper 10 is attached to the vehicle body 2. can be Also, in the above description, the female down stopper 10 or the male down stopper 12 is attached to the center pillar 4, but the member to which the down stopper 5 is attached can be appropriately changed with the same configuration. Further, in the above embodiment, a minute gap is formed between the concave portion 6 and the convex portion 7. It can also be set to be in full contact without forming a .
