  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the vehicle side part structure S according to the present embodiment relates to a structure capable of suppressing the displacement of the vehicle door 12 with respect to the vehicle body 10 at the time of a side collision, and as shown in FIG. It has a pin 14, a stopper 16, a facing portion 18, and a recess 20.

  The pin 14 protrudes inward in the vehicle width direction from the vehicle door 12 and is, for example, a metal round bar member that can be engaged with the vehicle body 10 side, and is provided with a tapered portion 14A on the distal end side (FIG. See also A)). Specifically, for example, a disk-shaped base portion 14B is fixed to or integrally formed with the outer end portion of the pin 14 in the vehicle width direction, and the base portion 14B is fixed to the mounting portion 22A of the mounting bracket 22. Yes. The mounting bracket 22 is fixed to the outer surface in the vehicle width direction of the door inner panel 24 at the upper and lower joint portions 22B and 22C, and the mounting portion 22A is more in the vehicle width direction than the mounting portion 24A of the stopper 16 in the door inner panel 24. It is spaced apart from the outside. As a result, a closed section 26 is formed between the mounting bracket 22 and the door inner panel 24. As shown in FIG. 4A, the mounting portion 24A is formed as a through hole into which the stopper 16 can be fitted, and the pin 14 protrudes inward in the vehicle width direction of the door inner panel 24 through the through hole. It is in a state.

  The stopper 16 is an elastic body such as rubber that is provided in an annular shape around the pin 14 in the vehicle door 12 and regulates the closing position of the vehicle door 12 with respect to the vehicle body 10. As shown in FIGS. 3 and 4A, the stopper 16 is formed in a substantially cylindrical shape with a bottom that is open at the outer side in the vehicle width direction, and is surrounded by the annular portion 16A at the inner side in the vehicle width direction. The center end face 16B thus formed is closed. A mounting groove 16D is provided on the outer periphery of the stopper 16 along the circumferential direction. The stopper 16 covers the pin 14 from the inner side in the vehicle width direction, and the mounting portion 24A of the door inner panel 24 is mounted in the mounting groove 16D. It is inserted in.

  As shown in FIG. 4A, an insertion hole 28 into which the pin 14 is inserted is provided in the annular portion 16A of the stopper 16, and in this case, for example, it contacts the pin 14 at normal time. For example, the contact portions 16C are provided at three locations. The contact portion 16C is provided so that the stopper 16 can be supported by the pin 14 so that the stopper 16 does not fall down when the vehicle door 12 is closed.

  Specifically, the contact portion 16C is, for example, a rib extending in the axial direction of the pin 14 on the inner surface of the annular portion 16A, and as shown in FIG. 4B, three locations in the inner circumferential direction of the annular portion 16A. And are inclined with respect to the axial direction of the pin 14 so as to approach each other toward the back surface of the central end surface 16B of the stopper 16. From the viewpoint of making the stopper 16 difficult to fall, it is desirable that the contact portion 16C is in contact with the distal end of the tapered portion 14A of the pin 14, for example, far from the mounting portion 24A of the stopper 16. Note that the contact portions 16C are not limited to three places, and may be provided, for example, at four places.

  As shown in FIG. 3, when the vehicle door 12 is closed, the stopper 16 abuts against the opposing portion 18 on the vehicle body 10 side and is slightly elastically deformed. Therefore, as shown in FIG. For example, a gap 30 larger than the elastic deformation amount is set between the tip of 14 and the back surface of the central end surface 16B of the stopper 16. That is, even when the stopper 16 is elastically deformed when the normal vehicle door 12 is closed, interference between the tip of the pin 14 and the back surface of the central end surface 16B of the stopper 16 is suppressed.

  In FIG. 3, the facing portion 18 is provided on the vehicle body 10 side and is a portion facing the annular portion 16A of the stopper 16 in the vehicle width direction when the vehicle door 12 is closed. As shown in FIG. 10 is an annular bulging portion provided on the side surface of the side member outer 32. The reason why the facing portion 18 is an annular bulging portion is to increase the rigidity of the facing portion 18 by increasing the section modulus of the facing portion 18, so that when the stopper 16 abuts against the facing portion 18 due to a side collision. Can suppress the deformation of the facing portion 18 and can secure more engagement allowance of the pin 14 with respect to the vehicle body 10.

  In FIG. 3, the concave portion 20 is provided on the vehicle body 10 side, and is a portion that is opposed to the pin 14 in the vehicle width direction when the vehicle door 12 is closed and is recessed inward in the vehicle width direction from the facing portion 18. As shown in FIG. 2, it is located at the center of the opposed portion 18 provided as an annular bulge. The recess 20 has a diameter that allows the tip of the pin 14 to enter during a side collision, and the strength of the recess 20 is determined by the pin 14 when the pin 14 comes into strong contact during a side collision. It is set to the extent that it can break through.

  As shown in FIG. 3, for example, a body outer reinforcement 34 is disposed on the inner side in the vehicle width direction of the side member outer 32. For example, a burring hole 34 </ b> A that is larger than the diameter of the recess 20 is formed in the portion to be formed. Further, for example, an exterior panel 36 is provided below the vehicle door 12. The reason why the recess 20 is not a through hole similar to the burring hole 34A is to prevent moisture and the like from entering the vehicle body 10 from the side member outer 32 which is the outer plate of the vehicle body 10 during normal use. It is.

(Function)
This embodiment is configured as described above, and the operation thereof will be described below. As shown in FIG. 2, in the vehicle side part structure S, an annular stopper that regulates the closing position of the vehicle door 12 with respect to the vehicle body 10 around the pin 14 protruding inward in the vehicle width direction from the vehicle door 12. 16 is provided, and the pin 14 is concealed in the stopper 16, so that the pin 14 is not exposed when the vehicle door 12 is opened, and the appearance is good. Further, as shown in FIG. 3, the mounting portion 22A of the pin 14 in the vehicle door 12 is disposed farther outward in the vehicle width direction than the mounting portion 24A of the stopper 16 in the vehicle door 12. It is possible to set the strength and rigidity required for the mounting portion.

  As shown in FIG. 3, when the vehicle door 12 is closed, the stopper 16 is momentarily brought into contact with the facing portion 18, and the closing position of the vehicle door 12 with respect to the vehicle body 10 is restricted. At this time, a reaction force against a part of the inertial force of the vehicle door 12 is applied as a load from the vehicle body 10 side to the stopper 16, and the load is formed in an annular shape on the side member outer 32. It is transmitted in the vehicle width direction from the facing portion 18 to the annular portion 16A of the stopper 16, and is absorbed by elastic deformation of the annular portion 16A.

  As shown in FIG. 4A, since a gap 30 larger than the elastic deformation amount of the annular portion 16A is set between the back surface of the central end surface 16B and the tip of the pin 14 in the stopper 16, Even when the annular portion 16A is elastically deformed, interference between the tip of the pin 14 and the back surface of the central end surface 16B of the stopper 16 is suppressed. For this reason, when the normal vehicle door 12 is closed, the load input from the vehicle body 10 to the pin 14 is suppressed, so that the pin facing portion due to the interference between the pin 14 and the vehicle body 10 in the vehicle width direction, that is, the stopper 16 Deterioration of the central end face 16B can be suppressed. In the stopper 16, the three contact portions 16C are inclined with respect to the axial direction of the pin 14 so as to approach each other toward the back surface of the central end surface 16B and are in contact with the pin 14. By setting the contact portion 16 </ b> C flexibly, it is possible to obtain an equivalent deterioration suppression effect for the central end surface 16 </ b> B of the stopper 16.

  The contact portion 16C is in contact with the pin 14 at the normal time so that the stopper 16 can be supported by the pin 14 when a load is input to the stopper 16 when the vehicle door 12 is closed. Thus, the stopper 16 can be prevented from falling.

  Next, the operation when a side collision occurs will be described. In FIG. 5, when a side collision load F acts on the vehicle door 12 due to a side collision, first, the lower portion of the vehicle door 12 moves inward in the vehicle width direction until the stopper 16 contacts the facing portion 18. When the lower portion of the vehicle door 12 further moves inward in the vehicle width direction, as shown in FIG. 6, the pin 14 penetrates the central end surface 16B of the stopper 16 and enters the recess 20 (see FIG. 3). It will be in the state engaged with the recessed part 20. FIG. At this stage, since the lower portion of the vehicle door 12 is constrained by the vehicle body 10, the displacement of the vehicle door 12 relative to the vehicle body 10, particularly the displacement of the vehicle door 12 upward and the inner side in the vehicle width direction. It becomes possible to suppress the displacement to.

  When the lower part of the vehicle door 12 moves further inward in the vehicle width direction, as shown in FIG. 7, the pin 14 now breaks through the recess 20 (see FIG. 6) and enters the burring hole 34A of the body outer reinforcement 34. By entering, the side member outer 32 and the body outer reinforcement 34 are engaged. As a result, the lower portion of the vehicle door 12 is firmly restrained by the vehicle body 10, so that the displacement of the vehicle door 12 upward relative to the vehicle body 10 and the displacement inward in the vehicle width direction is further suppressed. It becomes possible to do.

  In the vehicle side part structure S, since the taper part 14A is provided on the tip end side of the pin 14, it is easy to break through the central end face 16B and the recessed part 20 of the stopper 16. Further, in the vehicle side portion structure S, the mounting portion 22A of the pin 14 is disposed farther outward in the vehicle width direction than the mounting portion 24A of the stopper 16, and is relatively relative to the mounting portion 24A in a side collision. Therefore, even after the door inner panel 24 approaches or abuts the side member outer 32, the pin 14 can be further inserted inward in the vehicle width direction. For this reason, the pin 14 can pierce the stopper 16 and the recessed part 20, and can ensure the stroke for engaging with the vehicle body 10 side easily. In addition, this makes it possible to engage the pin 14 more deeply with the vehicle body 10 and more firmly restrain the lower portion of the vehicle door 12 with respect to the vehicle body 10.

  Thus, in the vehicle side part structure S, it is possible to improve the appearance when the vehicle door 12 is opened during normal use, and to suppress the displacement of the vehicle door 12 during a side collision. This vehicle side part structure S is not limited to the hinge type vehicle door 12 but can be applied to a sliding type vehicle door or a double door type vehicle door (both not shown).

  In FIG. 2, a load transmission member (not shown) may be provided between the attachment portion 22 </ b> A of the pin 14 and the door outer panel 38. In this case, since a load is directly transmitted from the door outer panel 38 to the pin 14 at the time of a side collision, the pin 14 can be engaged with the vehicle body 10 more efficiently, and the vehicle door 12 can be engaged with the vehicle body 10. The displacement can be further suppressed.

  Moreover, in the said embodiment, although the pin 14 was mentioned as an example of a protrusion part, a protrusion part is not restricted to the pin 14, It can engage with the vehicle body 10 at the time of a side collision, and can suppress the displacement of the vehicle door 12. Any shape can be used. When a shape other than the pin 14 is used as the protruding portion, the shapes of the stopper 16, the facing portion 18, and the recessed portion 20 are appropriately selected according to the shape of the protruding portion.

It is a perspective view of the vehicle provided with the vehicle side part structure. It is a perspective view which shows the site | part of the stopper in the opened vehicle door, and the opposing part and recessed part of a vehicle body.
