  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 easily shine the step body itself with the lamp unit, and is advantageous in terms of design, but the lamp unit is placed on the step body on which feet are placed when getting on and off. Therefore, it is necessary to maintain sufficient rigidity and strength while protecting the lamp unit.

  Accordingly, the present invention is intended to provide a vehicle step that can be attached to a step body in a state where the lamp unit is protected from external force while avoiding an increase in size and weight of the step body.

The vehicle step according to the present invention, in order to solve the above problems, comprises an elongate step body arranged substantially along the lower edge of the vehicle door opening (e.g., step body 11 of the embodiment), wherein The step body includes a top plate (for example, the top plate 14 of the embodiment) whose upper surface is used as a scaffold when getting on and off, a bottom plate (for example, the bottom plate 15 of the embodiment) disposed below the top plate, and a longitudinal direction. A support beam (for example, the support beam 17a of the embodiment) that extends along the direction and connects the top plate and the bottom plate, and irradiates the step body with light toward the top of the step body. In the vehicle step to which the lamp unit to be mounted (for example, the lamp unit 18 of the embodiment) is attached , the lamp unit receives the lamp (for example, the lamp body 19 of the embodiment) and the light emitted from the lamp body. Light guide (For example, the light guide 20 of the embodiment), and an accommodation space (for example, the accommodation space 25 of the embodiment) is provided on the longitudinal end of the step body and on the longitudinal extension of the support beam. And the lamp body of the lamp unit is arranged in the housing space.

With the above-described configuration, the rigidity and strength of the step body are maintained high by the top plate and the bottom plate and the support beam connecting them along the longitudinal direction. The lamp body of the lamp unit is arranged in the accommodating space on the longitudinal end of the step main body and the longitudinal extension of the support beam, so that it is difficult to receive a load from the central area of the step main body where passengers step on their feet. Become. In addition, since the housing space for housing the lamp body is provided on the longitudinal end of the step body and on the longitudinal extension of the support beam, the rigidity of the central region of the step body on which the passenger gets on foot And has little effect on strength. In addition, since the lamp body of the lamp unit is disposed in the accommodating space located on the longitudinal extension of the support beam in the step body, the load of passengers input to the top board is less likely to act directly. .

The lamp unit includes the light guide body that extends along a longitudinal direction of the step body, receives light emitted from the lamp body at an end surface, and guides the light to an upper surface side, and the light guide body includes: A window portion (e.g., a holding hole 23 of the embodiment) provided in the support beam and continuous in the longitudinal direction, and the top plate exposes a part of the light guide upward ( For example, the window portion 24) of the embodiment may be provided.
In this case, the light guide is protected from the passenger's load input to the top plate by being held in the holding hole of the support beam. Moreover, since the light guide irradiates light above the step body through the window formed on the top plate, the upper surface of the light guide is protected by the edge portion of the window. In other words, since the upper surface of the light guide exposed to the outside is disposed inside the edge of the window, foreign matter such as mud and pebbles attached to the shoe sole of the passenger and the shoe sole placed on the top plate Becomes difficult to directly contact the surface of the light guide. Therefore, by adopting this configuration, the light guide can be protected without increasing the size and weight of the lamp unit.

The lamp unit is disposed between the lamp body and the light guide, and condenses the light emitted from the lamp body and diffuses and irradiates a wide range of the light guide (for example, implementation) The diffusion attachment 21) may be provided, and the diffusion attachment may be disposed in the housing space together with the lamp body.
In this case, not only the lamp body of the lamp unit but also the diffusion attachment is arranged in a compact manner in the accommodating space at the end of the step body in the longitudinal direction.

The lamp body may be attached to a bracket (for example, the bracket 27 of the embodiment) fastened and fixed to the end surface in the longitudinal direction of the step body.
In this case, since the lamp body of the lamp unit is disposed in the accommodation space via a bracket fastened and fixed to the end surface in the longitudinal direction of the step body, the mounting portion of the lamp body occupies a lot of space in the step body. In addition, the bracket effectively increases the rigidity of the end of the step body in the longitudinal direction.

The lamp unit extends along a longitudinal direction of the step body, receives a light irradiated from the lamp body at an end surface, and guides the light to an upper surface side; the lamp body and the light guide A diffusion attachment that is disposed between the bodies and collects the light emitted from the lamp body and diffuses and irradiates the light over a wide range of the light guide, and the longitudinal direction of the diffusion attachment and the light guide The end may be attached to the bracket via the lamp.
In this case, not only the lamp body of the lamp unit, but also the diffusion attachment and the light guide are attached to the end of the step body in the longitudinal direction via the same bracket. Therefore, by adopting this configuration, it becomes possible to mount the lamp unit in the step body in a compact and easy manner.

The step body is supported so as to be able to advance and retreat to the vehicle body side via a rotatable support arm (for example, the support arm 10C of the embodiment), and the support arm has a guide bracket along the extending direction of the support arm. (For example, the guide bracket 40 of the embodiment) is attached, and a wiring cable (for example, the wiring cable 50 of the embodiment) that connects the lamp unit and the wiring portion on the vehicle body is hidden from the vehicle exterior side of the guide bracket. It may be attached via a resin clip (for example, the resin clip 41 of the embodiment).
In this case, when the support arm is turned, the wiring cable follows the operation of the support arm via the resin clip and the guide bracket. At this time, the behavior of the wiring cable is restricted to a predetermined range by the guide bracket and is hidden from the outside of the vehicle by the guide bracket. Therefore, by adopting this configuration, it is possible to prevent the wiring cable from interfering with surrounding members, and to improve the appearance from the outside.

According to this invention, the rigidity and strength of the entire area of the step body are maintained high by the top plate , the bottom plate, and the support beam, and the housing provided on the longitudinal extension of the support beam at the longitudinal end portion of the step body. Since the lamp body of the lamp unit is disposed in the space, it is possible to attach the lamp unit to the step body while protecting the lamp unit from external force while avoiding an increase in size and weight of the step body.

For example, when the main switch of the vehicle step 8 is in the ON state, the controller moves the step body 11 to the side of the vehicle body when any one of the side doors 5 and 6 on the front seat side and the rear seat side is opened. 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. The height is reduced by a height h corresponding to the distance including the thickness of the plate 14.

FIG. 10 is a view showing a section obtained by removing the lamp unit 18 from the inside and cutting the step body 11 at the same position as the section VIII-VIII in FIG. 3.
The step body 11 is provided with an accommodation space 25 for accommodating the lamp body 19 and the diffusion attachment 21 of the lamp unit 18 at one end in the longitudinal direction (end on the rear side of the vehicle body). The accommodation space 25 is formed by partially cutting one end side in the longitudinal direction of the support beam 17a in the step body 11 integrally formed by extrusion. Specifically, one end in the longitudinal direction of the outermost support beam 17a in the vehicle width direction is cut out over a predetermined length range by a tool such as an end mill, whereby the outer side plate 16 and the central support beam 17b are cut. An accommodation space 25 sandwiched between the two is formed on one end side in the longitudinal direction of the step body 11.

As shown in FIGS. 6 to 8, in the lamp unit 18, the diffusion attachment 21 is attached to the front surface of the lamp body 19 including the LED and the light emitting circuit by screws or the like, and the longitudinal direction of the light guide 20 is mounted on the front surface of the diffusion attachment 21. The direction end is fixed by screws or the like. In the lamp unit 18 integrated in this manner, the lamp body 19 is screwed and fixed to a bracket 27 made of a flat metal plate. The bracket 27 is overlaid on the end face in the longitudinal direction of the step main body 11 with the lamp unit 18 attached to one side surface, and is fixed to the end face of the step main body 11 with screws or the like in this state. At this time, the light guide 20 of the lamp unit 18 attached to the bracket 27 is inserted into the holding hole 23, and the lamp 19 and the diffusion attachment 21 are arranged in the accommodation space 25.
Note that an end cap 22 is attached to the end of the step body 11 in the longitudinal direction to which the bracket 27 is attached as described above so as to cover the outside of the bracket 27.

In addition, as shown in FIG. 8, the other end of the light guide 20 in the step body 11 is positioned in a state where one end side in the longitudinal direction of the light guide 20 is fixed to the step body 11 via the bracket 27. On the other side, an expansion / contraction allowance space 55 that allows the light guide 20 to expand and contract in the longitudinal direction is provided. This expansion / contraction allowance space 55 is relative to the longitudinal direction when the thermal environment changes greatly due to the difference in linear expansion coefficient between the step body 11 made of aluminum alloy and the light guide 20 made of acrylic resin. It is provided to allow displacement. That is, the expansion / contraction allowance space 55 is such that the other end of the light guide 20 is connected to another mounting member even when the other end of the light guide 20 in the longitudinal direction is displaced in the extension direction with respect to the step body 11 at the maximum. Is set so as not to interfere with.
The window 24 on the foremost side of the step body 11 that exposes the light guide 20 to the outside is when the other end in the longitudinal direction of the light guide 20 is displaced in the contraction direction to the maximum with respect to the step body 11. Further, the end portion of the light guide 20 is formed at a position where it is not exposed from the window portion 24 on the foremost side.

FIG. 11 is a cross-sectional view corresponding to the XI-XI cross section of FIG. 7 showing the connecting portion on the distal end side of the support arm 10C connected to one end side (vehicle body rear side) of the step body 11 in the longitudinal direction. FIGS. 12 and 13 are diagrams showing the upper surface and the lower surface of a single support arm 10C, respectively.
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. It has been.
The wiring cable 50 is locked to the inner surface side of the side guide wall 40b of the guide bracket 40 (the side facing the side surface of the support arm 10C) via the resin clip 41 in the distal end side region 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, in the vehicle step 8 according to this embodiment, the top plate 14, the bottom plate 15, and the support beam 17 a of the step body 11 are extruded by the aluminum alloy together with the other support beams 17 b and 17 c and the side plate 16. A housing space 25 formed by cutting away a part of the support beam 17a is formed at the longitudinal end of the step body 11, and the lamp body 19 of the lamp unit 18 is disposed in the housing space 25. ing. For this reason, in the vehicle step 8 according to this embodiment, the rigidity and strength of almost the entire region of the step body 11 can be maintained high by the top plate 14, the bottom plate 15, and the support beam 17 a that are integrally formed by the extrusion molding. In addition, since the lamp body 19 of the lamp unit 18 is disposed in the housing space 25 formed by cutting out a part of the support beam 17a at one end in the longitudinal direction, the step body 11 is prevented from being large and heavy. On the other hand, the lamp unit 18 can be attached to the step body 11 while being protected from external force.

  Further, in the case of the vehicle step 8 according to this embodiment, a part of the support beam 17a is cut off at the end in the longitudinal direction separated from the central region of the step body 11 where the passenger gets on the foot. 25 is formed, it hardly affects the rigidity and strength of the central region of the step body 11 where the passenger gets on the foot. Further, it is difficult for the passenger's load input to the central region of the top plate 14 to act directly on the lamp body 19 of the lamp unit 18 disposed in the accommodation space 25. In particular, since the lamp body 19 of the lamp unit 18 is disposed in the accommodation space 25 located on the longitudinal extension of the support beam 17 a in the step body 11, the load of passengers input to the top plate 14. Is difficult to act directly.

  Further, in the vehicle step 8 according to this embodiment, the support beam 17a of the step body 11 is provided with a holding hole 23 continuous in the longitudinal direction, and the long light guide 20 of the lamp unit 18 is provided in the holding hole 23. Is inserted and arranged, and a window portion 24 for exposing a part of the light guide 20 upward is provided on the top plate 14 of the step body 11. 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.

  In particular, in the case of this embodiment, since the window portion 24 is provided in the hollow portion 26 that is depressed by one step from the upper surface 14a of the top plate 14, the light guide 20 is formed from the shoe sole of the passenger on the top plate 14. The distance to the upper surface becomes longer, and it is possible to effectively prevent the surface of the light guide 20 from being damaged by the shoe soles of the passengers and foreign matters attached to the shoe soles.

  In the vehicle step 8 according to this embodiment, not only the lamp body 19 of the lamp unit 18 but also the housing space 25 at the end in the longitudinal direction of the step body 11 formed by cutting out a part of the support beam 17a. The diffusion attachment 21 is also arranged in a compact manner. Therefore, by adopting this configuration, the step body 11 can be further reduced in size and weight.

  In the vehicular step 8 according to this embodiment, a plate-like bracket 27 is overlapped and fastened to the end surface of the step body 11 in the longitudinal direction, and the lamp body 19 of the lamp unit 18 is attached to the bracket 27. ing. For this reason, the attachment portion of the lamp body 19 does not occupy much space in the step body 11, and the step body 11 can be further reduced in size and weight. In the case of this configuration, the rigidity of the end portion of the step body 11 in the longitudinal direction can be effectively increased by the plate-like bracket 27 fastened and fixed to the end surface of the step body 11 in the longitudinal direction.

  In particular, in the case of the vehicle step 8 according to this embodiment, not only the lamp body 19 of the lamp unit 18 but also the diffusion attachment 21 and the light guide body 20 are connected to the longitudinal end of the step body 11 via the same bracket 27. Therefore, the lamp unit 18 can be mounted in the step body 11 in a compact and easy manner.

Further, in the vehicle step 8 according to this embodiment, the step body 11 is supported by the mounting base 9 on the vehicle body side via the pivotable support arms 10A, 10B, 10C so as to be able to advance and retreat. A guide bracket 40 extending in the outgoing direction is fixed to the rear support arm 10 </ b> C, and a wiring cable 50 is attached to a portion of the guide bracket 40 that is hidden from the outside of the vehicle via a resin clip 41.
For this reason, the wiring cable 50 flexibly follows the operation of the support arm 10C via the resin clip 41 and the guide bracket 40 when the support arms 10A, 10B, and 10C are rotated. Specifically, when the support arm 10 </ b> C is rotated by the pivot portion on the base side and the tip side, the wiring cable 50 is flexibly held by the guide bracket 40 by the resin clip 41, and excessive deflection of the wiring cable 50 is guided. It is regulated by the bracket 40. In particular, in this embodiment, since the side guide wall 40b is provided on the guide bracket 40, the lateral bulge of the wiring cable 50 accompanying the rotation of the support arm 10C is reliably regulated by the side guide wall 40b. can do.
