DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described herein. In all drawings, the same elements are given the same reference numerals, and duplicated explanations will be omitted. In the following description, unless otherwise specified, terms indicating directions and orientations such as front, back, left, right, up, down, etc. indicate directions and orientations related to the vehicle. In each drawing, the arrow FR points forward, the arrow UP points upward, and the arrow RH points rightward.
[0011] FIG. 1(a) is a perspective view showing a part of a body panel 12, showing the rear side of a door opening on the right side of the vehicle. This door opening is located next to the driver's seat. The vehicle 10 is equipped with a fixing device for a side door, which serves as a vehicle door. The fixing device for the side door holds the side door in a closed position by a latch of a door lock provided on the door side removably engaging with a hook 32 (see FIG. 1(b)) of a door striker 20 fixed to the body panel 12. Note that a known engagement structure between the door striker and the door lock can be adopted, and is also disclosed in Patent Document 1.
[0012] FIG. 1(b) is an enlarged view of portion A in FIG. 1(a) and shows the door striker 20 in detail. The door striker 20 according to this embodiment includes a door striker body 22 and a height-raising plate 24. The door striker body 22 has the same structure as a typical door striker, but the legs 32A, 32B of the hook 32 are shorter by the height of the height-raising plate 24 (see FIGS. 2(b1) and (b2)). As shown in FIG. 1(b), the height-raising plate 24 is disposed between the vehicle body panel 12 and the base plate 30 of the door striker body 22.
[0013] The door striker body 22 is made of metal. The door striker body 22 includes a hook 32 and a base plate 30 to which the hook 32 is connected. The base plate 30 is formed in a plate shape and has two holes 36 (see FIG. 2(b2)) for passing two bolts 38. As shown in FIG. 1(b), the hook 32 is fixed to the front side of the base plate 30. The hook 32 is a round bar-shaped member bent into a U-shape. The hook 32 includes a pair of left and right legs 32A, 32B arranged along the front-rear direction, and a connecting portion 32C that connects the tips of the legs 32A, 32B in the vehicle width direction. The rear ends of the legs 32A, 32B respectively constitute root portions 32AR, 32BR connected to the base plate 30.
[0014] The raised plate 24 is made of metal and has relatively high rigidity. As shown in Fig. 1(c), the raised plate 24 is a plate-like member, and both its front and back surfaces (surfaces that contact the base plate and the vehicle body panel) are flat. The raised plate 24 has a plate body 50 and two holes 52 provided in the plate body 50. The two holes 52 are bolt holes for passing two bolts 38 (see Fig. 1(b)).
[0015] Two nuts (not shown) are fixed to the back side of the body panel 12. Two bolts 38 are passed through two holes 36 (see FIG. 2(b2)) of the base plate 30 and two holes 52 (see FIG. 1(c)) of the height-raising plate 24, and are screwed into the two nuts on the back side of the body panel 12. In this way, the door striker body 22 and the height-raising plate 24 are fixed to the body panel 12. Note that in FIG. 1(b), the tool insertion hole (the central hole of the bolt 38) for tightening the bolt 38 is drawn as a circle for simplification, but in reality, it has a shape that matches the standard of the screw head (hexalobular internal or triple square).
[0016] 2(a1) and (a2) are diagrams showing a conventional door striker 120. FIG. 2(b1) and (b2) are diagrams showing the door striker 20 according to this embodiment. FIG. 2(a1) and (b1) are diagrams showing the door strikers 120 and 20 as viewed from above, with the base plates 130 and 30 and the height-raising plate 24 shown in cross section. FIG. 2(a2) and (b2) are diagrams showing the door strikers 120 and 20 as viewed from the right side, with the base plates 130 and 30 and the height-raising plate 24 shown in cross section. In these diagrams, the bolts are omitted.
[0017] The conventional door striker 120 is composed of only a door striker body 122. The distance from the vehicle body panel 12 to the front end of the hook 132 of the conventional art (the upper end in Figs. 2(a1) and (a2)) is the same as the distance from the vehicle body panel 12 to the front end of the hook 32 of this embodiment (the upper end in Figs. 2(b1) and (b2)). The dashed square with reference symbol LP in Fig. 2 indicates the engagement position (meshing position) of the latch of the door lock with the legs 132A and 32A of the hooks 132 and 32. The distance from the vehicle body panel 12 to the latch engagement position LP is also the same between the conventional door striker 120 and the door striker 20 of this embodiment.
[0018] In the door striker 20 according to this embodiment, as shown in Fig. 2 (b1) and (b2), the legs 32A and 32B of the door striker body 22 are shorter by the height of the height-raising plate 24. Regarding the distances L1 and L2 (see Fig. 2 (a1) and (b1)) from the lower ends (ends on the rear side of the vehicle) of the legs to the upper ends (ends on the front side of the vehicle) of the latch engagement position LP, the distance L2 in this embodiment is shorter than the distance L1 in the conventional technology (L2>L1). In addition, regarding the distances L3 and L4 (see Fig. 2 (a2) and (b2)) from the upper ends (ends on the front side of the vehicle) of the bases 32AR and 132AR of the legs 32A and 132A to the lower ends (ends on the rear side of the vehicle) of the latch engagement position LP, the distance L4 in this embodiment is shorter than the distance L3 in the conventional technology (L3>L4).
[0019] Next, the function and effect of the door striker 20 according to this embodiment will be described.
[0020] According to the door striker 20 of this embodiment, the legs 32A, 32B of the hook 32 of the door striker body 22 can be shortened by the length of the raising plate 24. This makes it possible to suppress deformation of the hook 32 against the force applied to the hook 32 by the door lock latch. In other words, the rigidity of the hook 32 (striker shaft) can be improved.
[0021] In the case where the leg 132A of the hook 132 is long as in the conventional technology shown in FIG. 2(a2), when a load F1 is applied from the door lock latch in the vehicle vertical direction (the left-right direction in FIG. 2(a2)), the hook 132 is easily deformed (easily falls) in the vehicle vertical direction. When the hook 132 falls in the vehicle vertical direction, the upper part (the left part in FIG. 2(a2)) or the lower part (the right part in FIG. 2(a2)) of the base plate 130 at the base applies a load F2 to the vehicle body panel 12 so as to dent the vehicle body panel 12. This causes the vehicle body panel 12 to deform, so that the hook 132 falls further in the vehicle vertical direction. FIG. 3(a) is a diagram showing the schematic positions of the door hinge 18 and the door striker 120 (or 20) in the side door 16 of the vehicle 10. When the hook of the door striker 120 moves in the vertical direction, the A-pillar is easily deformed so as to fall via the door hinge 18. In addition, the rattle between the side door 16 and the vehicle body panel 12 becomes large.
[0022] However, according to the door striker 20 of this embodiment, since the legs 32A, 32B of the hook 32 are short, it is possible to suppress the hook 32 from falling in the vertical direction of the vehicle. In addition, it is possible to suppress deformation of the vehicle body panel 12. Therefore, it is possible to suppress rattling between the side door 16 and the vehicle body panel 12, and it is possible to improve the rigidity of the vehicle body and the turning performance of the vehicle 10. In other words, according to this embodiment, it is possible to obtain the same effects as the invention described in Patent Document 1, even with a door striker 20 having a very simple structure.
[0023] According to this embodiment, the door striker body 22 is attached to the vehicle body panel 12 with the raising plate 24 (high rigidity plate) sandwiched therebetween, so that the load received by the door striker body 22 can be transmitted to the vehicle body panel 12 over a wide area. FIG. 3(b) shows an example of the result of checking the contact pressure between the door striker and the vehicle body panel 12 using pressure-sensitive paper before and after the vehicle is driven. Areas with high contact pressure are shown in dark black. In the conventional door striker 120, pressure-sensitive paper (copy paper) is placed between the door striker 120 (door striker body 122) and the vehicle body panel 12 for checking, whereas in the door striker 20 according to this embodiment, pressure-sensitive paper (copy paper) is placed between the raising plate 24 and the vehicle body panel 12 for checking. From FIG. 3(b), it can be seen that in the conventional technology, the door striker 120 makes local contact with the vehicle body panel 12 only around the fastening portion. On the other hand, in this embodiment, the raised plate 24 is in contact with the entire surface of the vehicle body panel 12, and it can be seen that the local pressure on the vehicle body panel 12 can be reduced.
[0024] Incidentally, some door striker base plates in the prior art are not flat but have a shape that partially contacts the vehicle body panel, which makes it easy for localized pressure to be applied to the vehicle body panel 12. However, as in this embodiment, by attaching the door striker body 22 to the vehicle body panel 12 with the raising plate 24 in between, it is possible to suppress the application of localized load to the vehicle body panel 12.
[0025] In addition, according to this embodiment, it is possible to use another door striker body 22 having legs 32A, 32B of different lengths by changing the thickness of the raising plate 24. By changing the thickness of the raising plate 24, it is possible to change the latch engagement position LP of the hook 32 relative to the leg 32A.
[0026] In addition, since the door striker 20 is located in a place that is visible to the user when getting in and out of the vehicle, adding the height-raising plate 24 can create a sense of distinction for the vehicle 10.
[0027] In addition, according to the present embodiment, since the side surface of the height-raising plate 24 is exposed, the design of the vehicle 10 can be improved by changing the color, engraving, etc. of the side surface (or the entire surface) of the height-raising plate 24. The height-raising plate 24 can be selected and replaced according to the user's preference.
[0028] Furthermore, according to this embodiment, the above-mentioned advantageous effects can be obtained simply by replacing the existing door striker. [Explanation of symbols]
