Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, the down stopper is set to stably hold the slide door by pressing the stopper on the slide door side against the stopper on the vehicle body side when the slide door is closed.

[0006] However, depending on manufacturing errors of the slide door or the vehicle body, or mounting accuracy, etc., a minute gap or insufficient pressing force may occur between the concave portion and the convex portion, and the portion sandwiching the gap may repeatedly collide due to vibrations during vehicle travel, generating abnormal noises.

[0007] On the other hand, it is conceivable to increase the amount of pressure contact between the stoppers to such an extent that the generation of a gap between the concave portion and the convex portion can be sufficiently prevented. However, in this case, the opening and closing operability of the sliding door may be impaired, and the durability and wear resistance of the down stopper may be reduced.

[0008] An object of the present invention is to provide a vehicle structure that can prevent the generation of abnormal noise with a simple and inexpensive structure without pressing the fitting member between the sliding door and the vehicle body.

Means for Solving the Problems

[0009] In order to achieve the above object, a vehicle structure according to the present invention is provided with a pair of fitting members on a sliding door provided on a side portion of a vehicle body and a portion of the vehicle body that faces the sliding door when the door is closed. Recessed portions and convex portions that can be fitted to each other are formed on the pair of fitting members, and magnetic force is applied to the recessed portions and the convex portions in a direction intersecting the direction in which the convex portions enter the recessed portions. When the concave and convex portions are fitted, the inner surface of the concave portion One side repels the convex portion Between by magnetism And the magnetism that makes the convex part contact the other surface of the inner surface of the concave part is imparted.

Effects of the Invention

[0010] As described above, according to the present invention, since magnetism is imparted to the concave and convex portions of the fitting members provided on the sliding door and the vehicle body, when the door is closed, the concave and convex portions of the fitting members can be kept in either a contact state or a separated state by the magnetism. Thereby, even if a minute gap is formed between the concave portion and the convex portion of the fitting member, the collision between the concave portion and the convex portion due to the vibration during vehicle travel can be prevented or mitigated, and the generation of abnormal noise can be prevented with a simple and inexpensive structure without pressing the fitting member.

[0011] Regarding magnetism, for example, it can be applied to the four surfaces of both inner surfaces of the recess and both outer surfaces of the protrusion that fits inside it. By applying magnetism that generates a repulsive force to two sets of inner surfaces of the recess and outer surfaces of the protrusion, the recess and the protrusion can be kept in a separated state. In this case, in addition to preventing the collision of the recess and the protrusion, the contact itself between the recess and the protrusion can be prevented, and the durability and wear resistance of the fitting member can be improved.

[0012] Also, by applying magnetism that generates a repulsive force to one set of inner surface of the recess and outer surface of the protrusion, and applying magnetism that generates an attractive force to the other set of inner surface of the recess and outer surface of the protrusion, the protrusion can be kept in a contact state on the adsorption side with respect to the recess. In this case, by the combination of the repulsive force and the attractive force, the recess and the protrusion can be effectively brought into contact and the contact state can be maintained.

[0013] Furthermore, by applying magnetism by an electromagnet to the recess and the protrusion, magnetism can be applied only during the running of the vehicle, and while preventing the collision between the recess and the protrusion due to the vibration during vehicle running, the opening and closing operability of the sliding door can be improved.

Modes for Carrying Out the Invention

[0015] Hereinafter, modes for carrying out the vehicle structure according to the present invention will be described with reference to the drawings.

[0016] FIG. 1-2 As shown in 2 , the vehicle structure 1 according to the present invention is provided with a slide door 3 provided at a rear side portion of a vehicle body 2 and a center pillar 4 facing the front end of the slide door 3 when the door is closed in the vehicle body 2, and a down stopper 5 as a pair of fitting members is provided. Recesses 6 and protrusions 7 that can be fitted to each other are formed in the down stopper 5, and magnetic force in a direction in which the two can be separated when fitted is applied to the recesses 6 and the protrusions 7. Between directional magnetism And the magnetism in the direction of contact is applied.

[0017] The slide door 3 is disposed at a side portion of the vehicle body 2 and behind the center pillar 4, and is slidably attached to the vehicle body 2 in the front-rear direction, and its front end faces the center pillar 4 when the door is closed.

[0018] The center pillar 4 is formed in the vicinity of the center in the front-rear direction of the side portion 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 disposed in front of the center pillar 4.

[0019] The down stopper 5 is composed of a film down stopper 10 formed by forming a long hole-shaped recess 6 in a base plate 9 having a mounting hole 9a, and a male down stopper 12 formed by forming a protruding piece-shaped protrusion 7 in a base plate 11 having a mounting hole 11a.

[0020] The film down stopper 10 is attached to two upper and lower positions at the front end of the slide door 3, and the male down stopper 12 is attached to the rear end of the center pillar 4 with the positions in the vertical direction and the horizontal direction aligned with the film down stopper 10. By closing the slide door 3, the protrusion 7 of the male down stopper 12 enters and fits into the recess 6 of the film down stopper 10.

[0021] The recess 6 has an inner surface set as a gentle inclined surface such that the minimum width is at the position slightly intruding from its opening edge, and it becomes wider toward the inner side from there. The minimum width is set to be, for example, about 0.2 mm larger than that of the convex portion 7. Magnets 13 and 14 are embedded in the recess 6 with their end faces aligned with both inner surfaces of the portion having the minimum width, and the recess 6 is imparted with magnetism.

[0022] The convex portion 7 is set to have a constant width along its protruding direction. Magnets 15 are embedded in the convex portion 7 with their end faces aligned with both outer surfaces of the portion facing the magnets 13 and 14 in the fitted state to the recess 6, and the convex portion 7 is imparted with magnetism.

[0023] For reference As shown in Fig. 3, the magnets 13 and 14 in the recess 6 and the magnet 15 in the convex portion 7 are set such that in the fitted state, the S pole of the magnet 13 faces the S pole of the magnet 15, and the N pole of the magnet 14 faces the N pole of the magnet 15. Can be done are.

[0024] According to the above configuration, the magnets 13 and 14 are embedded in the recess 6 of the fender down stopper 10 provided on the slide door 3, and the magnet 15 is embedded in the convex portion 7 of the fender down stopper 12 provided on the center pillar 4. The S poles and N poles of the magnets 13 and 14 are respectively opposed to the S pole and N pole of the magnet 15. Therefore, when the door is closed, the recess 6 and the convex portion 7 can be kept in a separated state by the repulsive force of the magnetic force.

[0025] Thereby, without pressing the recess 6 and the convex portion 7 of the down stopper 5 against each other, while forming a minute gap of, for example, about 0.1 mm between them, the momentum of the collision between the recess 6 and the convex portion 7 due to the vibration during vehicle running can be suppressed to a level where the hitting sound cannot be heard, preventing the generation of abnormal noise. Moreover, the contact itself between the recess 6 and the convex portion 7 can be blocked, improving the durability and wear resistance of the down stopper 5.

[0026] The strength of the repulsive force is set to 633 N, for example, with the gap between each of the magnets 13, 14 and the magnet 15 being 0.1 mm, the magnetic flux density of the magnets 13, 14 and the magnet 15 being 200 mT, and the end face being 5 mm × 10 mm. However, by checking the actual machine and changing and adjusting the magnetic force, it is possible to cope with cases where abnormal excessive input is assumed.

[0027] Note that the present invention is not limited to the above-described embodiments, and appropriate changes can be made within the scope of the present invention. For example, by imparting magnetism by an electromagnet to the concave portion 6 and the convex portion 7, magnetism may be imparted only during the running of the vehicle. Thereby, it is possible to prevent the opening and closing operability of the sliding door 3 from being impaired by the magnetism imparted to the concave portion 6 and the convex portion 7, and it is possible to improve the opening and closing operability of the sliding door 3 while preventing the collision between the concave portion 6 and the convex portion 7 due to the vibration during vehicle running.

[0028] Also, In the present invention As shown in FIG. 4, the magnets 13, 14 in the concave portion 6 and the magnet 15 in the convex portion 7 are in a fitted state, with the S pole of the magnet 13 facing the S pole of the magnet 15 and the S pole of the magnet 14 facing the N pole of the magnet 15. Do .

[0029] In this case, when the door is closed, the repulsive force between the magnets 13 and 15 and the attractive force between the magnets 14 and 15 can keep the side of the concave portion 6 where the magnet 14 is provided and the convex portion 7 in contact with each other, preventing the collision between the concave portion 6 and the convex portion 7 due to the vibration during vehicle running and preventing the generation of abnormal noise.

[0030] Alternatively, instead of attaching the film-down stopper 10 to the sliding door 3 and the mail-down stopper 12 to the vehicle body 2, the mail-down stopper 12 may be attached to the sliding door 3 and the film-down stopper 10 may be attached to the vehicle body 2. Also, in the above description, the film-down stopper 10 or the mail-down stopper 12 is attached to the center pillar 4, but if the configuration is the same, the member to which the down stopper 5 is attached can be appropriately changed. Further, in the above embodiment, a minute gap is formed between the concave portion 6 and the convex portion 7, but if magnetism is imparted to the concave portion 6 and the convex portion 7, they can be set to be in complete contact without forming a gap therebetween.
