Description

  The present invention relates to a vehicle step disposed substantially along a lower edge of a door opening of a vehicle body.

2. Description of the Related Art A vehicle is known in which steps are deployed to the outside of a vehicle body in order to make it easier for passengers to get on and off when opening a vehicle door.
The vehicle step employed in this type of vehicle is desired to allow the occupant to accurately grasp the position of the step body even when the outside of the vehicle is dark.
For this reason, a vehicle step including a lamp unit that illuminates the step body when an occupant gets on and off has been devised (see, for example, Patent Documents 1 and 2).

In the vehicle step described in Patent Document 1, a lamp unit for irradiating the upper surface of the step body is attached to the side portion of the vehicle body.
Further, in the vehicle step described in Patent Document 2, the lamp unit that irradiates light upward from the upper surface of the step body is near the deepest position in the depth direction (the innermost position in the vehicle width direction) of the upper surface of the step body. Is attached.

JP 2009-208666 A JP 2006-205853 A

  The vehicle step described in Patent Document 1 has a limitation in causing the step body to shine brightly when getting on and off because the lamp unit for illuminating the upper surface of the step body is attached to the side of the vehicle body that is separated from the step body. , It tends to be poor in design.

  On the other hand, the vehicle step described in Patent Document 2 can illuminate the step body itself with the lamp unit, which is advantageous in terms of design, but the lamp unit is located at the deepest position in the depth direction of the upper surface of the step body. Since it is attached in the vicinity, there is a case where the light of the lamp unit is not conspicuous when getting on. As a countermeasure, it is conceivable to arrange the lamp unit closer to the front side in the depth direction on the upper surface of the step body. In this case, the light irradiation part of the lamp unit is easily stepped on directly by the shoe sole and adheres to the shoe sole. There is a concern that the mud or pebbles may damage the lamp unit.

  Therefore, the present invention is intended to provide a vehicle step that can effectively protect the lamp unit from being stepped on from above while arranging the light irradiation part of the lamp unit in a portion that is easily noticeable when riding. is there.

In order to solve the above-described problem, the vehicle step according to the present invention is arranged substantially along the lower edge of the door opening of the vehicle body, and the top surface is used as a scaffold when getting on and off (for example, the ceiling of the embodiment). a plate 14), a support beam connecting the bottom plate is disposed below the top plate (e.g., the bottom plate 15 of the embodiment), wherein the top plate the top plate extending along the longitudinal direction of the said bottom plate (e.g., a support beam 17a of the embodiment) step body to have a a, (e.g., step body 11 of the embodiment), the lighting unit for irradiating light toward above the step body (e.g., lighting of the embodiment In the vehicle step to which the unit 18) is attached, the lamp unit includes a lamp body that irradiates light (for example, the lamp body 19 of the embodiment), and extends along the longitudinal direction of the step body. Irradiated And a light guide (for example, the light guide 20 of the embodiment) that guides the light upward to the upper surface of the step body, and is located outside the center of the step body in the vehicle width direction. Is provided with a holding hole that is continuous in the longitudinal direction (for example, the holding hole 23 in the embodiment), both side walls of the holding hole are formed by the support beams, the light guide body is in contact with the support beams, and A plurality of windows that are accommodated in the holding hole so that the upper surface thereof is lower than the upper surface of the step body, and a part of the light guide is exposed on the top plate at a position directly above the holding hole. Parts (for example, the window part 24 of the embodiment) are formed apart from each other in the longitudinal direction of the step body, and the top plate between the plurality of window parts is constructed on the both side walls of the support beam. did.

With the above configuration, the light guide that receives light from the lamp body and guides the light upward from the upper surface of the step body is disposed outside the center of the step body in the vehicle width direction. Will shine on the near side of the step body, and the passenger will be able to see the light reliably. In addition, since the upper surface of the light guide is disposed below the upper surface of the step body, the upper surface of the light guide is not easily stepped on directly by the shoe sole. Moreover, the light guide is protected from a passenger's load input to the top plate by being held in the holding hole of the support beam.

A recess (for example, a recess 26 in the embodiment) extending in the longitudinal direction of the step body is formed on the top surface of the top plate, and the window is formed on the bottom surface of the recess. good.
In this case, the window itself that exposes a part of the upper surface of the light guide to the outside is disposed in the recess of the step body, so that the shoe sole of the passenger on the upper surface of the step body contacts the light guide. It becomes difficult to do. Therefore, the light guide can be more reliably protected by adopting this configuration.

At least one of the support beams is connected to the top plate by branching from the upper end of the upright portion (for example, the upright portion 17a-1 of the embodiment) standing upward from the bottom plate and bifurcating from the upper end of the upright portion. Branching portions (for example, the branching portion 17a-2 of the embodiment), and the branching portions may constitute the both side walls.

The light guide has one end in the longitudinal direction fixed to the step body, and the other end of the light guide in the step body in the longitudinal direction is positioned on the side of the light guide in the longitudinal direction. An expansion / contraction allowance space (for example, the expansion / contraction allowance space 55 of the embodiment) that allows the expansion / contraction of the image forming apparatus may be provided.
In this case, even if the extension length in the longitudinal direction is relatively changed between the step body and the light guide due to the difference in the linear expansion coefficient between them, the light guide has only one end in the longitudinal direction. Since it is fixed to the step main body and an expansion / contraction allowance space is provided on the other end side, a relative change in the extension length in the longitudinal direction of the step main body and the light guide is absorbed in the expansion / contraction allowance space. Therefore, by adopting this configuration, it is possible to prevent an excessive stress from acting between the light guide and the step body due to a heat change.

The window portion formed on the top plate is preferably provided at a position where the end portion of the light guide is not exposed when the light guide is thermally contracted.
In this case, even when the light guide body is thermally contracted to the maximum, the end of the light guide body is not exposed to the outside through the window portion, so the light irradiation of the light guide body through the window portion changes. Or the appearance from the outside can be prevented from deteriorating.

  According to this invention, since the light guide that guides light above the upper surface of the step body is disposed outside the center of the step body in the vehicle width direction, the user can be sure to visually recognize the light irradiation. In addition, since the upper surface of the light guide is disposed below the upper surface of the step body, the upper surface of the light guide is stepped on by the shoe sole and is guided by mud, pebbles, etc. attached to the shoe sole. It is possible to prevent the light body from being damaged.

The step body 11 is stored below the vehicle body when the side doors 5 and 6 on the front seat side and the rear seat side are both closed.

FIG. 5 is a view showing a cross section corresponding to the VV cross section of FIG. 3 of the step body 11, and FIG. 6 is an exploded view of a part of the step body 11. FIG. 7 is an enlarged plan view showing a part of the vehicle step 8, and FIG. 8 is a view showing a cross section of the step body 11 corresponding to the VIII-VIII cross section of FIG. FIG. 9 is a view showing a cross section corresponding to the IX-IX cross section of FIG.
The step body 11 is a long rectangular plate-like member disposed substantially along the side sill 7 on the side of the vehicle, and its basic shape is constituted by an extruded body made of an aluminum alloy. More specifically, the step body 11 includes a top plate 14 whose upper surface is used as a scaffold for passengers getting on and off, a bottom plate 15 disposed substantially parallel to the top plate 14 below the top plate 14, and the top plate 14. And a pair of side plates 16 that close the bottom plate 15 at the front and rear ends in the depth direction, and three support beams 17 a and 17 b that extend along the longitudinal direction and connect the top plate 14 and the bottom plate 15 between the pair of side plates 16. , 17c. The support beams 17a, 17b, and 17c are spaced apart from each other in the depth direction of the step body 11, and divide the inside of the step body 11 into a plurality of hollow portions. The top plate 14, the bottom plate 15, the side plate 16, and the three support beams 17a, 17b, and 17c of the step body 11 are integrally formed by extrusion of an aluminum alloy.

  In addition, a lamp unit 18 that irradiates light upward of the step body 11 is attached to the step body 11. The lamp unit 18 extends along the longitudinal direction of the step body 11 and the lamp body 19 including the LED and its light emitting circuit, receives the light emitted from the lamp body 19 at the end face, and guides the light to the upper surface side. A long light guide 20 and a diffusion attachment that is disposed between the lamp 19 and the light guide 20, collects the light emitted from the lamp 19, diffuses it over a wide area of the light guide 20, and irradiates it. 21. The light guide 20 is formed long by a transparent acrylic resin. The extension length of the light guide 20 in the longitudinal direction is set shorter than the extension length of the step body 11 in the longitudinal direction by a predetermined length. In addition, resin end caps 22 are attached to both ends in the longitudinal direction of the step body 11 by screws.

  Here, as shown in FIG. 5, the three support beams 17a, 17b, and 17c of the step body 11 formed by extrusion of the aluminum alloy are arranged so that the support beam 17a is located closest to the outer side in the vehicle width direction. Is arranged closest to the inside in the vehicle width direction. The central support beam 17b and the support beam 17c on the inner side in the vehicle width direction are relatively thin and have a substantially constant thickness. On the other hand, the support beam 17a on the outer side in the vehicle width direction is bifurcated in a substantially U shape from the thick upright portion 17a-1 standing upward from the bottom plate 15 and the upper end portion of the upright portion 17a-1. A branch portion 17a-2 that branches and is connected to the top plate 14 at the upper end. The branch portion 17 a-2 forms a holding hole 23 having a substantially rectangular cross section having an arc portion on the lower end side with the top plate 14. Since the support beam 17 a is integrally formed by extrusion together with the top plate 14 and the bottom plate 15, the holding hole 23 is formed continuously in the longitudinal direction of the step body 11. In the holding hole 23, the light guide 20 described above is inserted and held from the end in the longitudinal direction. Therefore, the light guide 20 is disposed along the longitudinal direction of the step body 11 at a position outside the center position C in the vehicle width direction of the step body 11. The upper surface of the light guide 20 held in the holding hole 23 is positioned below the upper surface of the step body 11.

A plurality of long hole-like window portions 24 extending along the longitudinal direction of the step body 11 are formed at positions directly above the holding holes 23 of the top plate 14. Four window portions 24 are provided at regular intervals in the longitudinal direction of the step body 11. Each window 24 exposes a part of the light guide 20 accommodated in the holding hole 23 to the upper side of the top plate 14. Therefore, the light emitted from the lamp body 19 of the lamp unit 18 is irradiated to the upper side of the step body 11 through the light guide 20 and the window portions 24 of the top plate 14.
In addition, on the top surface of the top plate 14, a concave groove-like recess 26 extending along the longitudinal direction of the top plate 14 is formed in order to prevent slipping of the shoe sole of the passenger. The depressions 26 are provided in a plurality of rows separated in the depth direction of the top plate 14. Each of the window portions 24 that expose the light guide 20 to the upper side of the top plate 14 is provided on the bottom surface portion of the recessed portion 26 that is located on the outermost side in the vehicle width direction. Therefore, as shown in FIG. 9, the upper surface of the light guide 20 held in the holding hole 23 has the depth of the recess 26 and the ceiling with respect to the upper surface 14a of the top plate 14 on which the shoe sole of the passenger is placed.

As shown in FIG. 11, a part of the side plate 16 on the depth side (vehicle width direction inner side) of the step body 11 and a part of the bottom plate 15 continuing to the side plate 16 are continuously cut out. A mounting plate 30 made of high-stiffness iron-based metal is attached to the notched portion. The attachment plate 30 is attached with a support shaft 31 for rotatably connecting the tip of the rear support arm 10C. The notched portion of the bottom plate 15 is closed by a separate cover plate 32. In FIG. 11, only the connection portion of the support arm 10C in the step body 11 is shown, but the connection portions of the other support arms 10A and 10B have the same structure.

As shown in FIGS. 6 and 7, the lamp body 19 of the lamp unit 18 is provided with an adapter 33 for receiving input of electric power and a control signal from the vehicle body side. The adapter 33 is connected to a wiring cable 50 that is connected to a wiring portion on the vehicle body side. In addition, the code | symbol 34 in FIG. 6 is a harness clip for hold | maintaining the cable which connects the adapter 33 and the main-body part of the lamp 19 to the bracket 27. FIG.
The wiring cable 50 connected to the adapter 33 is wired along the support arm 10C on the rear side.

As shown in FIGS. 12 and 13, a guide bracket 40 made of a metal plate is attached to the inner side wall of the curved portion of the support arm 10C on the rear side by welding. The guide bracket 40 has an upper wall 40a that projects substantially horizontally from the welded portion with the support arm 10C, and a side guide wall 40b that bends downward from the projecting end of the upper wall 40a. The upper wall 40a is formed continuously from the curved portion on the proximal end side of the support arm 10C to the straight portion on the distal end side, but the side guide wall 40b is provided only on the straight portion on the distal end side of the support arm 10C.

In the base end side region of 10C, the guide bracket 40 is locked to the lower surface side of the upper wall 40a of the guide bracket 40 via a resin clip 41.

  As described above, the vehicle step 8 according to this embodiment is provided with the holding hole 23 that has the window portion 24 on the upper surface and is continuous in the longitudinal direction at a position outside the center in the vehicle width direction of the step body 1. The light guide 20 of the lamp unit 18 is disposed outside the center in the vehicle width direction by being accommodated in the holding hole 23 of the step main body 11, and the upper surface of the light guide 20 is lower than the upper surface of the step main body 11. Since it is arranged to be on the side, the user can surely visually recognize the light irradiation on the near side in the depth direction of the step body 11, and the upper surface of the light guide 20 is stepped on by the shoe sole, It is possible to prevent the light guide 20 from being damaged by mud, pebbles or the like attached to the shoe sole. Therefore, by adopting this configuration, the light guide 20 can be reliably protected.

  Further, in the vehicle step 8 according to this embodiment, a window portion 24 that exposes a part of the light guide 20 upward is provided on the upper surface of the step body 11, and the window portion 24 is the upper surface of the step body 11. It is formed in the hollow portion 26. For this reason, the distance from the passenger's shoe sole placed on the upper surface of the step body 11 to the upper surface of the light guide 20 becomes longer, and the surface of the light guide 20 is caused by the foreign material attached to the shoe sole of the passenger or the shoe sole. Can be effectively prevented from being damaged.

  Further, in the vehicle step 8 according to this embodiment, the light guide 20 is disposed in the holding hole 23 continuous in the longitudinal direction provided in the support beam 17 a of the step body 11, and is disposed in the holding hole 23. A window portion 24 that exposes a part of the light guide 20 upward is formed on the top plate 14. For this reason, the light guide 20 is protected by the wall portion of the holding hole 23 formed in the support beam 17 a, and the passenger's load input from above the top plate 14 is difficult to be input to the light guide 20. In the vehicle step 8, the light of the light guide 20 is irradiated above the step body 11 through the window portion 24 formed on the top plate 14, so that it is exposed to the outside of the light guide 20. The upper surface to be protected can be protected by the edge portion of the window portion 24. Specifically, since the upper surface of the light guide 20 is disposed below the edge portion of the window portion 24, the shoe soles of passengers placed on the top board 14, mud, pebbles, etc. attached to the soles Can be prevented from coming into direct contact with the upper surface of the light guide 20. Therefore, by adopting this configuration, the light guide 20 can be reliably protected.
