The side step 1 is fixed to the vehicle body 101 by fixing the plurality of brackets 4 to the vehicle body 101. The support member 2 supports the cover member 3. Note that, in a portion where the support member 2 and the cover member 3 overlap, a cushioning material such as non-woven fabric may be provided between them.
[0015] Hereinafter, each part will be described in detail.
[0016] As shown in Figure 3, the support member 2 includes two fixing walls 2a, 2b, two standing walls 2c, 2d, a support wall 2e, and a protruding wall 2f. The support member 2 is made of a metal material such as aluminum. The support member 2 is also referred to as an aluminum plate.
[0017] The two fixing walls 2a, 2b are provided at intervals in the width direction (Y direction). The two fixing walls 2a, 2b are coupled (fixed) to the bracket 4 by a coupling member 11.
[0018] The two standing walls 2c, 2d are provided at intervals in the width direction (Y direction), and extend upward (in the +Z direction) from the ends on the vehicle outer side (+Y direction side) in the width direction of the two fixing walls 2a, 2b.
[0019] The support wall 2e is provided across the upper ends of the two standing walls 2c, 2d, and extends along the X-Y plane. The cover member 3 is overlapped on the support wall 29e, and the support wall 29e supports the cover member 3.
[0020] The protruding wall 2f projects from the vertical wall 2d in the opposite direction (+Y direction) from the vehicle body 101.
[0021] Figure 4 is a perspective view showing a part of the side step 1 according to an embodiment. As shown in Figures 3 and 4, the side step 1 is provided with a groove 2g and a plurality of holes 2h, 2i. Details of the groove 2g and other parts will be described later.
[0022] Figure 5 is a cross-sectional view showing side step 1 according to an embodiment. Figure 6 is a cross-sectional view showing side step 1 according to an embodiment. Figure 7 is a cross-sectional view showing side step 1 according to an embodiment. Figures 3, 5 to 7 are cross-sectional views in the YZ plane, but their positions in the X direction are different.
[0023] As shown in Figures 3, 5 to 7, the cover member 3 has a step portion 3a, a covering portion 3b, and a vertical wall portion 3c, and is supported (fixed) to the support member 2.
[0024] The step portion 3a is provided on the upper side of the support member 2. The cover portion 3b extends downward from the vehicle-outward end (+Y direction end), front end (-X direction end), and rear end (+X direction end) of the step portion 3a in the width direction. The cover portion 3b covers at least the vehicle-outward end (+Y direction end), front end (-X direction end), and rear end (+X direction end) of the support member 2 in the width direction. The vertical wall portion 3c extends upward (+Z direction) from the vehicle body 101 side (-Y direction side) end of the step portion 3a. The cover member 3 is made of synthetic resin material.
[0025] A tread surface 3aa is formed on the upper surface of the step portion 3a. The tread surface 3aa is the surface that is stepped on by a person. The tread surface 3aa is, for example, a decorative surface with an uneven shape. The tread surface 3aa is also called the stepping surface.
[0026] The covering portion 3b has a first portion 3ba and a second portion 3bc. The first portion 3ba extends downward from the step portion 3a. The second portion 3bc extends downward from the lower end of the first portion 3ba. The second portion 3bc is formed in a curved shape and, as it extends downward, it is directed toward the vehicle body 101 side (-Y direction side).
[0027] As shown in Figures 2 and 3, the cover member 3 is composed of a combination of multiple members. For example, the cover member 3 has a first cover member 6, a second cover member 7, and a third cover member 8. The first cover member 6, the second cover member 7, and the third cover member 8 are integrated with each other. The first cover member 6, the second cover member 7, and the third cover member 8 are each made of synthetic resin material. For example, the first cover member 6, the second cover member 7, and the third cover member 8 are different in color from each other.
[0028] As shown in Figure 3, the first cover member 6 includes a tread surface 3aa and a part of the step portion 3a. The first cover member 6 has a component 6a that constitutes the tread surface 3aa and a part of the step portion 3a.
[0029] The second cover member 7 includes a part of the step portion 3a and a part of the covering portion 3b. More specifically, the second cover member 7 has a component 7a that constitutes a part of the step portion 3a, a component 7b that constitutes the first portion 3ba of the covering portion 3b, and a component 7c that constitutes the second portion 3bc of the covering portion 3b. Component 7b is located below component 6a of the first cover member 6.
[0030] The third cover member 8 includes a vertical wall portion 3c, a part of the step portion 3a, and a part of the covering portion 3b. More specifically, the third cover member 8 has a component 8a that constitutes the vertical wall portion 3c, a component 8b that constitutes a part of the step portion 3a, and a component 8c that constitutes the covering portion 3b. Component 8b is located below component 6a of the first cover member 6, spaced apart from component 7a of the second cover member 7 towards the vehicle body 101 (-Y direction). Component 8c is located towards the vehicle body 101 (-Y direction) relative to components 7b and 7c of the second cover member 7, and protrudes downward from component 7c of the second cover member 7.
[0031] As shown in Figure 5, a connector 14 is integrally formed on the first cover member 6, and this connector 14 connects (fixes) the first cover member 6 and the second cover member 7. Also, as shown in Figure 6, the second cover member 7 and the third cover member 8 are connected (fixed) by a connector 13. Furthermore, as shown in Figures 6 and 7, the first cover member 6 is connected (fixed) to the support member 2 by connectors 12 and 16. Connector 12 is inserted into the hole 2i.
[0032] Next, the drainage structure of the side step 1 will be described. The drainage structure includes, for example, a groove 2g and a plurality of holes 2h, as shown in Figures 3 and 4. The groove 2g is formed between the support member 2 and the cover member 3. Specifically, the groove 2g is formed in the support member 2.
[0033] Figure 8 is a cross-sectional view showing a portion of the side step 1 according to the embodiment that includes the groove 2g. Figure 9 is a perspective view showing a portion of the side step 1 according to the embodiment that includes the groove 2g. Figure 10 is a bottom view showing a portion of the side step 1 according to the embodiment that includes the hole 2h of the groove 2g.
[0034] As shown in Figures 4 and 8, the groove 2g extends across the vertical wall 2d and the protruding wall 2f of the support member 2. That is, the groove 2g is located on the vehicle-outward side in the width direction relative to the gap between the second cover member 7 and the third cover member 8 in the cover member 3. The groove 2g extends in the front-rear direction. The groove 2g is formed in a concave shape that opens upward. The front end 2gb and rear end 2ga of the groove 2g are open. The front end 2gb and rear end 2ga of the groove 2g are connected to the outside below the support member 2 and the cover member 3.
[0035] The vertical wall 2d and the protruding wall 2f that form the groove 2g will be described in detail with reference to Figure 8. The vertical wall 2d has a lower wall 2da below the connection with the protruding wall 2f and an upper wall 2db above the connection with the protruding wall 2f. The protruding wall 2f has a first wall 2fa, a second wall 2fb, and a flange portion 2fc. The first wall 2fa extends outward in the width direction from the vertical wall 2d. The second wall 2fb extends from the first wall 2fa to the opposite side of the vehicle body 101, that is, outward and upward in the width direction of the vehicle. In other words, the second wall 2fb is inclined with respect to the vertical direction so that it goes upward as it goes outward in the width direction of the vehicle. The flange portion 2fc extends outward in the width direction of the vehicle from the second wall 2fb.
[0036] The groove 2g is formed by the upper wall 2db of the vertical wall 2d, the first wall 2fa of the protruding wall 2f, and the second wall 2fb of the protruding wall 2f. The upper wall 2db and the second wall 2fb are a pair of side walls of the groove 2g, and the first wall 2fa is the bottom wall of the groove 2g. The upper wall 2db, the first wall 2fa, and the second wall 2fb are examples of walls.
[0037] As shown in Figure 3, the step portion 3a of the cover member 3 rests on the flange portion 2fc. The flange portion 2fc functions as a support portion for the step portion 3a. The flange portion 2fc also serves as a reference part for an acceleration sensor mounted on the vehicle body 101, and receives a load during a collision (side impact) of the vehicle 100, transmitting that load to the acceleration sensor. Therefore, in this embodiment, the thickness t1 of the flange portion 2fc is greater than the thicknesses t2 to t4 of the upper wall 2db, the first wall 2fa, and the second wall 2fb, respectively. For example, the thickness t1 of the flange portion 2fc is 3 mm, and the thicknesses t2 to t4 of the upper wall 2db, the first wall 2fa, and the second wall 2fb, respectively, are 2 mm. Note that the thickness of each part is not limited to the above. This improves the rigidity of the flange portion 2fc. The upper wall 2db, the first wall 2fa, and the second wall 2fb are also referred to as the general portion in relation to the flange portion 2fc. Furthermore, the flange portion 2fc is thicker than the thickness of all other walls in the support member 2.
[0038] Furthermore, multiple holes 2h are provided in the first wall 2fa, which is the bottom wall of the groove 2g. The multiple holes 2h are spaced apart in the front-rear direction. The holes 2h penetrate the first wall 2fa and are provided to the outside on the lower side of the support member 2 and cover member 3.
[0039] Furthermore, as shown in Figures 9 and 10, the hole 2h has an insertion portion 2ha and a drainage portion 2hb. A connecting member 17 (Figure 10) for connecting the cover member 3 to the support member 2 is inserted into the insertion portion 2ha. Two drainage portions 2hb are provided adjacent to each other in front of and behind the insertion portion 2ha, and are capable of draining water from the groove portion 2g. In this embodiment, the hole 2h for connecting the cover member 3 to the support member 2 is widened in the front and back directions to form the drainage portions 2hb.
[0040] In the side step 1 with the above configuration, water may enter the interior of the side step 1 from below, for example, when the vehicle 100 is in motion. In Figure 3, the water intrusion path is indicated by arrow F1. As shown in Figure 3, for example, water from below enters the side step 1 from between the upper surface (matting surface) of the flange portion 2fc of the support member 2 and the lower surface (matting surface) of the step portion 3a of the cover member 3, proceeding inward in the vehicle width direction and entering the groove portion 2g. As shown in Figure 9, the water that enters the groove portion 2g is guided in the front-rear direction by the groove portion 2g and falls out from the front end portion 2gb, the rear end portion 2ga, and the drainage portion 2hb of the hole 2h, and is discharged to the outside on the lower side of the support member 2 and the cover member 3. In Figure 9, an example of the direction of water flow toward the rear end portion 2ga in the groove portion 2g is indicated by arrow F2. Also in Figure 9, the falling water 200 is schematically shown.
[0041] As described above, the side step 1 (vehicle step) 1 of this embodiment is provided on the lower side of the door 102 of the vehicle 100. The side step 1 comprises a support member 2 and a cover member 3. The support member 2 is fixed to the vehicle body 101 of the vehicle 100. The cover member 3 has a step portion 3a provided on the upper side of the support member 2 and a covering portion 3b that extends downward from the step portion 3a and covers the support member 2, and is supported by the support member 2. A groove portion 2g is provided between the support member 2 and the cover member 3, which is open to the outside on the lower side of the support member 2 and the cover member 3.
[0042] With this configuration, water entering from below the side step 1 enters the groove 2g between the support member 2 and the cover member 3, and is then discharged from the groove 2g to the outside below the support member 2 and the cover member 3. Therefore, with this configuration, it is possible to prevent water from entering from below the side step 1 from overflowing onto the upper side (tread surface 3aa side) of the side step 1. Consequently, it is possible to prevent the appearance of the side step 1 from being deteriorated by water. In addition, it is possible to prevent water from entering from below the side step 1 from accumulating inside the side step 1.
[0043] Furthermore, the groove 2g is provided in the support member 2.
[0044] With this configuration, the groove portion 2g can be formed relatively easily.
[0045] Furthermore, the support member 2 has an upper wall 2db, a first wall 2fa, and a second wall 2fb (wall) that form a groove 2g, and a flange portion 2fc extending from the second wall 2fb in the direction opposite to the vehicle body 101. The thickness t1 of the flange portion 2fc is greater than the thicknesses t2 to t4 of the upper wall 2db, the first wall 2fa, and the second wall 2fb, respectively.
[0046] With this configuration, the flange portion 2fc is less prone to deformation. Therefore, for example, the load applied to the flange portion 2fc is easily transmitted to the acceleration sensor installed on the vehicle body 101.
[0047] Furthermore, the first wall 2fa of the groove 2g is provided with a hole 2h that penetrates the first wall 2fa and leads to the outside on the lower side of the support member 2 and the cover member 3.
[0048] With this configuration, water that enters the groove 2g can be discharged from the hole 2h to the outside on the lower side of the support member 2 and the cover member 3.
[0049] Furthermore, the groove 2g is provided in the support member 2. The hole 2h has an insertion portion 2ha into which a connecting member 17 for connecting the cover member 3 to the support member 2 is inserted, and a drainage portion 2hb adjacent to the insertion portion 2ha that can discharge water from the groove 2g.
[0050] With this configuration, the hole 2h has both the function of attaching the cover member 3 and the function of drainage, so the configuration of the side step 1 can be simplified compared to when these functions are realized in separate holes 2h.
[0051] In the above embodiment, a side step 1 was shown as an example of a vehicle step, but the invention is not limited to this. For example, the vehicle step may be a back step provided below the back door of the vehicle 100.
[0052] Furthermore, although the above embodiment shows an example in which the groove 2g is provided on the support member 2, the invention is not limited to this. For example, a separate member may be provided between the support member 2 and the cover member 3, and the groove 2g may be provided on this separate member.
[0053] While embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations are possible without departing from the spirit of the invention. The above embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
