Abstract
Description
[Technical Field]
[0001] The present invention relates to a side stand structure. [Background technology]
[0002] BACKGROUND ART Conventionally, it is known that a side stand for a saddle-ride type vehicle in which the vehicle body is banked is formed to a desired strength and shape by casting or forging (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-271848 Summary of the Invention [Problem to be solved by the invention]
[0004] However, there is a demand for a configuration that makes the side stand sturdy while avoiding an increase in size and weight of the side stand and improving its appearance.
[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a side stand structure that can improve the appearance of the side stand, reduce its weight, and increase the strength of the side stand. [Means for solving the problem]
[0006] As a means for solving the above-mentioned problems, a first aspect of the present invention comprises a stand member (21) pivotally supported on one of the left and right sides of a vehicle body and rotatably provided between an upright position and a storage position, the stand member (21) comprising: a base (22) rotatably connected to the vehicle body; a ground contact portion (24) that comes into contact with the ground when the stand member (21) is in the upright position; and a plate-shaped connecting portion (23) that connects the base (22) and the ground contact portion (24), the plate thickness direction (F3) of the connecting portion (23) being arranged in the vehicle width direction when the stand member (21) is in the storage position, and a side edge portion of the connecting portion (23) along the extension direction (F1) between the base (22) and the ground contact portion (24) that is in contact with the ground when the stand member (21) is in the storage position. an upper edge portion (23c) located on the upper side in the vertical direction of the vehicle when the stand member (21) is in the storage position has a raised portion (26) that raises inward in the vehicle width direction in the plate thickness direction (F3), and a protruding portion (27) that protrudes outward in the vehicle width direction in the plate thickness direction (F3) on the side of the ground contact portion (24) in the extension direction (F1) of the upper edge portion (23c) and serves as an operating portion when rotating the stand member (21), the raised portion (26) and the protruding portion (27) respectively have a raised upper surface portion (26a) and a protruding upper surface portion (27a) that face upward in the vertical direction of the vehicle when the stand member (21) is in the storage position, and the raised upper surface portion (26a) and the protruding upper surface portion (27a) are formed flat and continuous with each other. According to this configuration, the stand member has a plate-shaped connecting portion (arm portion), which allows the weight of the stand member to be reduced, and the wide surface on one side of the connecting portion in the plate thickness direction to be the exterior surface, thereby improving the appearance. The raised portion (thick portion), which is the reinforcing portion of the connecting portion, and the protruding portion, which is the rotation operation portion of the stand member, are connected in a flush manner, so that input during stand operation can be distributed in the extension direction (length direction) of the stand member and effectively received.
[0007] A second aspect of the present invention is characterized in that, in the first aspect, the connection portion (23) has an outer surface portion (23a) facing outward in the vehicle width direction and an inner surface portion (23b) facing inward in the vehicle width direction, and the inner surface portion (23b) is located below the raised portion (26) when the stand member (21) is in the storage position. With this configuration, when the stand member is in the storage position, the inner surface of the connection portion is positioned below the raised portion, making the inner surface of the connection portion less visible and improving the appearance.
[0008] A third aspect of the present invention is characterized in that, in the first or second aspect, the raised portion (26) is located at the outer end of the connection portion (23) in the vehicle width direction when the stand member (21) is in the upright position. According to this configuration, the raised portion formed on one side edge of the plate-shaped connection portion is positioned at the outer end in the width direction of the vehicle when the stand is upright, making the plate-shaped connection portion appear thick when the stand is upright while making the inner surface of the connection portion less visible, thereby improving the appearance.
[0009] A fourth aspect of the present invention is characterized in that, in the above-mentioned second aspect, a vehicle body cover member (11eL) is provided that covers the periphery of the stand support portion (31) on the vehicle body, and the vehicle body cover member (11eL) is provided with a storage recess (34) that stores the stand member (21) in the storage position, and the inside of the storage recess (34) is provided with a protruding portion (36) that protrudes toward the inner surface portion (23b) of the stand member (21) in the storage position. According to this configuration, by providing the storage recess that stores the stand member in the storage position with a protruding portion that protrudes toward the inner surface of the stand member, the stand member and the vehicle body cover member are closer together in the stand stored state, reducing the gap between the stand member and the vehicle body cover member and improving the appearance. Although the storage recess is concave when viewed from outside the vehicle, even if a structure such as a vehicle frame is present on the back side of the storage recess, the protruding portion covers the structure, hiding it and improving the appearance in the stand raised state, while ensuring a gap between the structure and the vehicle body cover member and reducing interference between vehicle parts.
[0010] A fifth aspect of the present invention is characterized in that, in the above-mentioned fourth aspect, at least the end (36c) of the protrusion (36) on the inner surface (23b) side is close to a virtual area obtained by extending the rotation area (R1) of the stand member (21) in the circumferential direction, and the end (36c) of the protrusion (36) is located lower than the connection portion (23) of the stand member (21) in the storage position in the vertical direction of the vehicle. With this configuration, the end (top) of the protruding portion on the inner side of the stand is close to the extension of the rotation area of the stand member, and by positioning the top of the protruding portion lower than the connection portion, it is possible to position the raised portion higher than the top of the protruding portion, and space can be efficiently secured to avoid the raised portion and store the stand member. [Effects of the Invention]
[0011] According to the present invention, it is possible to provide a side stand structure that can improve the appearance of the side stand, reduce its weight, and increase the strength of the side stand. [Brief explanation of the drawings]

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, directions such as front, rear, left, and right are the same as those in the vehicle described below unless otherwise specified. In addition, in the drawings used in the following description, an arrow FR indicating the front of the vehicle, an arrow LH indicating the left side of the vehicle, and an arrow UP indicating the top of the vehicle are shown in appropriate locations. In the following description, it is assumed that the vehicle body is parked upright without tilting left or right, and is in an empty vehicle 1G state on a horizontal plane.
[0014] <Entire vehicle> 1 shows a scooter-type motorcycle 1 as an example of a saddle-ride type vehicle according to an embodiment. The motorcycle 1 is equipped with a front wheel 3, which is a steering wheel, and a rear wheel 4, which is a drive wheel. The front wheel 3 is supported by a pair of left and right front forks 3a, and can be turned (steered) by a handlebar 2. The rear wheel 4 is supported by a swing-type power unit 8, and can be driven by the power unit 8.
[0015] Steering system components including the handlebars 2, front forks 3a, and front wheel 3 are rotatably (steerably) supported on a head pipe 16a at the front end of a body frame 16. A front portion of a power unit 8 is supported on a lower portion of the body frame 16 so as to be able to swing up and down. The body frame 16 includes a head pipe 16a, a down frame 16b extending downward and rearward from the head pipe 16a, a lower frame 16c extending rearward from the lower portion of the down frame 16b, and a rear frame 16d extending rearward and upward from the rear of the lower frame 16c.
[0016] A floor step 6 on which the driver places his or her feet is provided between the front wheel 3 and the rear wheel 4. A front body 14 is provided in front of the floor step 6. A rear body 15 is provided behind the floor step 6. A space K1 above the floor step 6 between the front body 14 and the rear body 15 serves as a straddle space K1 for the driver to straddle the vehicle body. A handlebar 2 is located above the front body 14. A seat 5 on which a passenger sits is supported above the rear body 15. A foldable side stand device 20 is provided on the lower left side of the floor step 6, which can support the vehicle body in an upright position with it tilted to the left.
[0017] The power unit 8 includes, for example, an electric motor M as a drive source, and a transmission mechanism (for example, a gear-type reducer) T that transmits the drive force generated by the electric motor M to the rear wheels 4. The electric motor M and the transmission mechanism T are provided on the left arm portion of the power unit 8 that is configured as a swing arm. The power unit 8 may have various configurations, and may, for example, include an internal combustion engine as a drive source. A driving battery BT that stores power for driving is mounted below the seat 5.
[0018] The periphery of the body frame 16 of the motorcycle 1 is covered with a body cover 11. The body cover 11 includes a front body cover 11a that forms the outer surface of the front body 14, a rear body cover 11b that forms the outer surface of the rear body 15, and a floor cover 11c that forms the floor step 6. The floor cover 11c includes a step board 11d that forms the footrest surface (upper surface of the floor), left and right floor side covers 11e that extend downward from the outer side edges of the step board 11d in the vehicle width direction, and an undercover 11f that covers the underside of the floor step 6.
[0019] <Side stand device 20> Fig. 2 is a left side view of the side stand device 20 in a retracted state, Fig. 3 is a left side view of the side stand device 20 in an upright state, Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 2, and Fig. 5 is a cross-sectional view taken along line VV in Fig. 3. The floor side cover 11e on the left side of the vehicle body is indicated by the reference symbol 11eL. 2 to 5, the side stand device 20 can be rotated between a stored position (folded position, see FIGS. 2 and 4) in which the tip end (ground contact portion 24 side) of the stand member (stand bar) 21 is flipped up rearward of the rotating shaft 25, and an upright position (used position, see FIGS. 3 and 5) in which the tip end of the stand member 21 extends below the rotating shaft 25. The states in FIGS. 2 and 4 are called the stand stored state, and the states in FIGS. 3 and 5 are called the stand upright state. Line C1 in the figures indicates the central axis of the rotating shaft 25.
[0020] 3 and 4, the side stand device 20 is attached to the left side (left lower frame 16cL) of the pair of left and right lower frames 16c. The side stand device 20 includes a stand bracket 31 fixed to the left lower frame 16cL and a stand member 21 rotatably supported by the stand bracket 31.
[0021] 6 is a side view of the stand member 21 as seen from the axial direction of the rotation shaft 25, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. The stand member 21 will be described below, and unless otherwise specified, the stand member 21 in the stored state will be described. 2 to 7, stand member 21 extends linearly from the base end side (stand bracket 31 side) to the tip end side (ground contact portion 24 side). Stand member 21 includes a pivot portion (base portion) 22 rotatably connected to the vehicle body side (stand bracket 31), a ground contact portion 24 spaced away from pivot portion 22 toward the tip end side and capable of contacting the ground when the stand is upright, and a plate-shaped connecting portion (arm portion) 23 extending linearly between pivot portion 22 and ground contact portion 24 and connecting pivot portion 22 and ground contact portion 24. Stand member 21 is integrally formed as a forged part made of, for example, an aluminum alloy.
[0022] The pivot portion 22 is bifurcated and sandwiches the stand connecting portion 32 of the flat stand bracket 31 in the plate thickness direction. The pivot portion 22 includes a pair of plate portions 22a, 22b. The plate portions 22a, 22b are arranged parallel to each other and spaced apart in the plate thickness direction of the stand connecting portion 32. A groove portion 22c is formed between the plate portions 22a, 22b, into which the stand connecting portion 32 is inserted so as to be rotatable relative to each other. A shaft insertion hole, through which the rotation shaft 25 is inserted, is formed coaxially in both plate portions 22a, 22b. A stand switch (rotary switch) 25d, which detects whether the stand is in an upright position, is arranged coaxially on the outer side of the plate portion 22a on the outer side in the vehicle width direction.
[0023] The stand member 21 is rotatably connected (supported) to the stand bracket 31 via the pivot shaft 25 by inserting the stand connecting portion 32 of the stand bracket 31 into the groove portion 22c of the pivot portion 22 and attaching a pivot shaft 25 that passes through the pivot portion 22 and the stand connecting portion 32.
[0024] The pivot shaft 25 is inclined upward so that it is positioned higher on the outer side in the vehicle width direction. As a result, when the stand member 21 is rotated from the stand-stored state to the stand-up state, the stand member 21 extends so as to protrude outward in the vehicle width direction. As a result, the ground contact portion 24 is positioned outward in the vehicle width direction, making it easier to support the vehicle body in an upright state. Also, when the stand member 21 is in the stand-stored state, the protrusion of the stand member 21 outward in the vehicle width direction is suppressed. As a result, the stand member 21 is less likely to contact the ground when the vehicle body is banked. The pivot shaft 25 may be inclined so that it is positioned further forward or rearward on the outer side in the vehicle width direction.
[0025] When the stand is stored, the connection portion 23 is arranged so that its thickness direction (arrow in the figure) faces the vehicle width direction. The thickness direction of the connection portion 23 is inclined relative to the vehicle width direction so that the outer sides in the vehicle width direction are positioned higher in the vehicle vertical direction. Arrow F1 in Fig. 5 indicates the extension direction of the connection portion 23 between the pivot portion 22 and the ground contact portion 24. Arrow F2 in Fig. 4 indicates the width direction spanning the upper and lower edges in the cross section of the connection portion 23, and arrow F3 indicates the thickness direction at the center of the width in the cross section of the connection portion 23.
[0026] Of the pair of side edges along the extension direction of the connection portion 23, the side edge located on the upper side in the vertical direction of the vehicle (and on the outer side in the vehicle width direction) when the vehicle is stored in the stand is referred to as the upper edge portion 23c, and the side edge located on the lower side in the vertical direction of the vehicle (and on the inner side in the vehicle width direction) when the vehicle is stored in the stand is referred to as the lower edge portion 23d. The upper edge portion 23c extends substantially horizontally when the vehicle is stored in the stand, except for the base end side (front end side). The base end side (front end side) of the upper edge portion 23c is cut out at a gentle slope so that the plate width of the connection portion 23 decreases toward the base end side. The base end side (front end side) of the upper edge portion 23c is connected to the pivot portion 22 with its plate width narrowed. The lower edge portion 23d extends substantially horizontally overall when the vehicle is stored in the stand, and the base end side (front end side) is directly connected to the pivot portion 22.
[0027] 4 and 7, when the stand is stored, a raised portion 26 is formed on the inner side of the upper edge 23c of the connecting portion 23 in the vehicle width direction, protruding inward in the vehicle width direction in the plate thickness direction. The raised portion 26 has a tapered triangular shape in cross section and protrudes inward in the vehicle width direction, making the upper edge 23c of the connecting portion 23 thicker in the plate thickness direction. The raised portion 26 forms a substantially horizontal raised upper surface 26a that faces upward in the vehicle up-down direction in the stand stored state. Furthermore, the raised portion 26 forms an apex 26b located at the end on the inner side in the vehicle width direction in the stand stored state, and a raised lower surface 26c that extends diagonally downward and outward in the vehicle width direction from the apex 26b.
[0028] A locking hook 29 for locking one end (rear end) of the stand spring (tension coil spring) SP is provided in the middle (not limited to the central part) in the length direction (extension direction) of the connection part 23 of the stand member 21. The locking hook 29 is, for example, integrally formed with the connection part 23 (it may be welded).
[0029] A protrusion (footrest) 27 is provided on the tip end of the connecting portion 23, which protrudes outward in the vehicle width direction together with the ground contact portion 24 when the stand is stored, and enables the user to rotate the stand member 21 with their feet. The protrusion 27 is formed integrally with the connecting portion 23 and the ground contact portion 24 (or may be welded), for example. The protrusion 27 will be described in detail later.
[0030] The connecting portion 23 has an outer surface portion 23a facing outward in the vehicle width direction and an inner surface portion 23b facing inward in the vehicle width direction. In a cross section perpendicular to the extension direction, the connecting portion 23 has a curved cross-sectional shape that is convex outward in the vehicle width direction. The concave inner surface portion 23b is located below the raised portion 26 in the stand-stored state. The upper portion of the inner surface portion 23b rises and merges with the raised lower surface portion 26c of the raised portion 26, with an increasing curvature. The upper portion of the inner surface portion 23b and the raised lower surface portion 26c are arranged to form an obtuse angle in a cross-sectional view. The upper portion of the outer surface portion 23a and the raised upper surface portion 26a are arranged to form an acute angle in a cross-sectional view.
[0031] In the stand-stored state, the concave inner surface 23b is hidden from above by the protrusion 26. As a result, even when a user looks down on the stand periphery from above in the stand-stored state, the concave shape (hollowed-out shape) of the connection portion 23 is not visible. In the stand-stored state, the connection portion 23 is curved to fit along the cover outer surface 11e1 of the left floor side cover 11eL, forming an appearance that is integrated with the left floor side cover 11eL. The connection portion 23 is not necessarily limited to a curved plate shape, but may be a flat plate shape, and may take any suitable shape depending on the surrounding shape.
[0032] When the stand member 21 rotates from the storage position to the upright position, the upper edge 23c of the connection portion 23 moves to the outer end of the connection portion 23 in the vehicle width direction. That is, when the stand member 21 is upright, the raised portion 26 is located at the outer end of the connection portion 23 in the vehicle width direction, with the raised upper surface 26a facing outward in the vehicle width direction. When the stand member 21 is upright, the outer surface 23a of the connection portion 23 faces outward and forward in the vehicle width direction in front of the connection portion 23. When the stand member 21 is upright, the concave inner surface 23b is hidden inside in the vehicle width direction. As a result, when the stand member 21 is upright, the hollowed-out shape of the connection portion 23 is not visible, and the raised upper surface 26a creates the appearance of an increased thickness for the plate-like connection portion 23.
[0033] 6 and 7, when viewed in the extension direction of connecting portion 23, grounding portion 24 forms a grounding surface 24a that is larger than the cross-sectional shape of connecting portion 23. When viewed in the extension direction of connecting portion 23, grounding portion 24 extends outward in the vehicle width direction in the plate thickness direction relative to the cross-sectional shape of connecting portion 23, and also partially protrudes downward in the axial direction of pivot shaft 25 and inward in the vehicle width direction.
[0034] A protrusion 27 is formed at a portion of the upper edge 23c of the connecting portion 23 on the ground contact portion 24 side in the extension direction (a portion adjacent to the ground contact portion 24), which protrudes outward in the vehicle width direction in the plate thickness direction of the ground contact portion 24 and serves as an operating portion when the user rotates the stand member 21. The end of the protrusion 27 on the ground contact portion 24 side is connected to and integrated with the extension portion 24b of the ground contact portion 24. The ground contact portion 24 extends outward in the vehicle width direction in line with the protrusion 27. The ground contact portion 24 and the protrusion 27 have the same amount of protrusion (extension) from the rear of the connecting portion 23 outward in the vehicle width direction. The extension portion 24b of the ground contact portion 24 extends at a slight incline toward the base end, extending the ground contact surface 24a outward in the vehicle width direction.
[0035] 2 to 7, the protruding portion 27 is formed parallel to the raised upper surface portion 26a and protrudes outward in the vehicle width direction. The protruding portion 27 (and the extended portion 24b of the ground contact portion 24) protrudes outward in the vehicle width direction beyond the cover outer surface (imaginary surface) 11e1 of the left floor side cover 11eL, making it easy for a user to place their foot on it. The protruding portion 27 has a substantially horizontal plate shape and protrudes outward in the vehicle width direction, so it is less likely to disrupt the flow of wind as the vehicle moves. A concave curved surface portion 28, as viewed from the outside in the vehicle width direction, is formed between the rear portion of the outer surface portion 23a of the ground contact portion 24, the lower surface portion 27b of the protruding portion 27, and the front surface portion 24c of the extended portion 24b of the ground contact portion 24, thereby smoothing the change in the cross-sectional shape of the stand member 21. The protruding portion 27 is inclined so that the front edge portion 27c is positioned more rearward as it approaches the outside in the vehicle width direction, so that the width (front-rear width) of the vehicle narrows as it approaches the outside in the vehicle width direction. The protrusion 27 is formed in a generally swept-back wing shape when viewed from above. The tip of the protrusion 27 is formed with a tip bent portion 27d that is bent upward, making it easier for the user to place their foot on it.
[0036] In the stand placement area of the left floor side cover 11eL, a storage recess 34 (described later) is formed, thereby cutting out the cover outer surface 11e1. Therefore, although the cover outer surface 11e1 in the stand placement area is a virtual surface, it is formed to be continuous with the surrounding cover outer surfaces 11e1. For example, the cover outer surface 11e1 in the stand placement area is formed symmetrically with the cover outer surface 11e1 of the right floor side cover 11e.
[0037] The protruding portion 27 forms a protruding upper surface portion 27a that faces upward in the vehicle vertical direction when the stand member 21 is in the storage position. The protruding upper surface portion 27a is formed to be continuous with the raised upper surface portion 26a in a flat shape (in this embodiment, flush). The protruding upper surface portion 27a and the raised upper surface portion 26a are continuous with each other in a flat shape (flush) without any steps or the like. The protruding upper surface portion 27a and the raised upper surface portion 26a may have a gentle curve to the extent that stress concentration does not occur.
[0038] 3 and 5, the stand bracket 31 is formed of a flat steel plate perpendicular to the axial direction of the rotation shaft 25 and has a thickness equivalent to that of the plate portions 22a, 22b of the pivot portion 22. The stand bracket 31 is fixed to the left lower frame 16cL by welding or bolting. The stand bracket 31 has a stand connecting portion 32 that is rotatably inserted into the groove portion 22c of the pivot portion 22. A shaft insertion hole is formed in the stand connecting portion 32, through which the shaft portion of the rotation shaft 25 is inserted. When the stand connecting portion 32 is inserted into the groove portion 22c of the pivot portion 22, the shaft insertion hole is coaxially arranged with the shaft insertion hole formed in the pair of plate portions 22a, 22b of the pivot portion 22.
[0039] Stoppers 32a1 and 32a2 that determine the rotational positions of the stand member 21 in the stand retracted state and the stand erected state are formed on the outer periphery of the stand connecting portion 32. Stopper abutment surfaces 22d1 and 22d2 that abut against the stoppers 32a1 and 32a2, respectively, are formed on the pivot portion 22 of the stand member 21.
[0040] The rotating shaft 25 has a so-called stepped bolt 25a as a shaft body. The stepped bolt 25a is inserted into and removed from the outer side in the vehicle width direction through the insertion holes of the pivot part 22 and the stand connecting part 32. The stepped bolt 25a has a head part located on the outer side in the vehicle width direction, a shaft part connected to the head part on the inner side in the vehicle width direction, and a threaded shaft protruding toward the inner side in the vehicle width direction of the pivot part 22.
[0041] The shaft portion of the stepped bolt 25a is inserted through the shaft insertion hole of the plate portion 22a on the outer side of the pivot portion 22 in the vehicle width direction and the shaft insertion hole of the stand connecting portion 32. The threaded shaft of the stepped bolt 25a is inserted through the shaft insertion hole of the plate portion 22b on the inner side of the pivot portion 22 in the vehicle width direction. A nut 25b is screwed onto and tightened onto the threaded shaft protruding inward in the vehicle width direction of the pivot portion 22, thereby fixing the stepped bolt 25a to the plate portion 22b on the inner side in the vehicle width direction. In this state, the pivot portion 22 is rotatably connected (supported) to the stand connecting portion 32 via the stepped bolt 25a.
[0042] The stand bracket 31 has a locking portion that locks the other end (front end) of the stand spring SP. The stand spring SP is stretched between the locking hook 29 of the stand member 21 and the locking portion of the stand bracket 31. The stand spring SP uses its own tension to maintain the rotation position of the stand member 21 in the upright position or the stored position. The direction in which the stand spring SP urges the stand member 21 changes at the midpoint of the rotation range; when it is closer to the upright position, it is urged toward the upright position, and when it is closer to the stored position, it is urged toward the stored position.
[0043] <Stand storage recess 34> 2 to 5, the left floor side cover 11eL that covers the periphery of the stand bracket 31 is formed with a storage recess 34 for storing the stand member 21 in the storage position. Referring to the cross section, the storage recess 34 is formed to be recessed inward in the vehicle width direction relative to the curved cover outer surface 11e1 of the left floor side cover 11eL that is convex downward and outward in the vehicle width direction. The storage recess 34 includes a substantially horizontal upper wall portion 34a that covers the upper end of the stand storage space, and an inner wall portion 34b that extends obliquely downward and inward in the vehicle width direction from the inner end of the upper wall portion 34a in the vehicle width direction.
[0044] Here, a plate-shaped frame member 16e is attached to the left and right lower frames 16c at a position overlapping the rear portion of the storage recess 34 in a side view, sandwiching the pipe-shaped left lower frame member 16cL in the vehicle width direction. To avoid this frame member 16e, a protruding portion (bulge) 36 is formed on the inner wall portion 34b of the storage recess 34, protruding downward and outward in the vehicle width direction. The protruding portion 36 includes a vertical wall portion 36a extending downward from near the outer end of the upper wall portion 34a, and a horizontal wall portion 36b extending substantially horizontally inward in the vehicle width direction from the lower end of the vertical wall portion 36a. The corners of the vertical wall portion 36a and the horizontal wall portion 36b form apexes 36c of the protruding portion 36. In the drawing, reference numeral 16f denotes a cross frame connecting the left and right lower frames 16c to each other.
[0045] The overhanging portion 36 overlaps the connecting portion 23 of the stand member 21 in the stored position in a side view. At this time, since the connecting portion 23 is formed in a plate shape with its plate thickness direction facing the vehicle width direction, a sufficient gap is secured between the overhanging portion 36 and the connecting portion 23. The top 36c of the overhanging portion 36 is close to an extension of the rotation region R1 of the stand member 21 (a virtual region obtained by extending the rotation region R1 in the circumferential direction). However, the top 36c of the overhanging portion 36 is located lower than the upper end of the connecting portion 23 of the stand member 21 in the stored position in the vehicle up-down direction. Therefore, the raised portion 26 formed on the upper edge portion 23c of the connecting portion 23 is unlikely to come close to the top 36c of the overhanging portion 36, and a localized decrease in the gap between the overhanging portion 36 and the stand member 21 is suppressed.
[0046] As described above, the side stand structure in the above embodiment includes a stand member 21 that is pivotally supported on one of the left and right sides of the vehicle body and is provided so as to be rotatable between an upright position and a retracted position, the stand member 21 includes a pivot portion 22 that is rotatably connected to the vehicle body, a ground contact portion 24 that comes into contact with the ground when the stand member 21 is in the upright position, and a plate-like connecting portion 23 that connects the pivot portion 22 and the ground contact portion 24, the plate thickness direction F3 of the connecting portion 23 being oriented in the vehicle width direction when the stand member 21 is in the retracted position, and the connecting portion 23 has a side edge portion along the extension direction F1 that extends between the pivot portion 22 and the ground contact portion 24, the side edge portion of the connecting portion 23 that extends along the extension direction F1 The upper edge portion 23c, which is located on the upper side in the vertical direction of the vehicle when the member 21 is in the storage position, is provided with a raised portion 26 that raises inward in the vehicle width direction in the plate thickness direction F3, and the portion of the upper edge portion 23c on the ground contact portion 24 side in the extension direction F1 (the portion adjacent to the ground contact portion 24) is provided with a protruding portion 27 that protrudes outward in the vehicle width direction in the plate thickness direction F3 and serves as an operating portion when rotating the stand member 21, and the raised portion 26 and the protruding portion 27 respectively have a raised upper surface portion 26a and a protruding upper surface portion 27a that face upward in the vertical direction of the vehicle when the stand member 21 is in the storage position, and the raised upper surface portion 26a and the protruding upper surface portion 27a are formed flush and continuous with each other.
[0047] According to this configuration, stand member 21 having plate-shaped connecting portion (arm portion) 23 can reduce the weight of stand member 21 and improve its appearance by using a wide surface on one side in plate thickness direction F3 of connecting portion 23 as the exterior surface. Since raised portion (thick portion) 26, which is a reinforcing portion of connecting portion 23, and protruding portion 27, which is rotation operation portion 27 of stand member 21, are connected in a flush manner, input during stand operation can be distributed and effectively received in extension direction (length direction) F1 of stand member 21.
[0048] In the above-described side stand structure, the connection portion 23 has an outer surface portion 23a facing outward in the vehicle width direction and an inner surface portion 23b facing inward in the vehicle width direction, and the inner surface portion 23b is located below the raised portion 26 when the stand member 21 is in the storage position. According to this configuration, when the stand member 21 is in the storage position, the inner surface of the connection portion 23 is located below the raised portion 26, making the inner surface of the connection portion 23 less visible and improving the appearance.
[0049] In the above-described side stand structure, the raised portion 26 is located at the outer end of the connecting portion 23 in the vehicle width direction when the stand member 21 is in the upright position. According to this configuration, the raised portion 26 formed on one side edge of the plate-shaped connecting portion 23 is positioned at the outer end in the width direction of the vehicle when the stand is upright, making the plate-shaped connecting portion 23 appear thick when the stand is upright while making the inner side of the connecting portion 23 less visible, thereby improving the appearance.
[0050] The above-mentioned side stand structure is provided with a vehicle body cover member (left floor side cover 11eL) that covers the periphery of the stand support portion (stand bracket 31) on the vehicle body, and the left floor side cover 11eL is provided with a storage recess 34 that stores the stand member 21 in the storage position, and the inside of the storage recess 34 is provided with a protruding portion 36 that protrudes toward the inner surface portion 23b of the stand member 21 in the storage position. According to this configuration, by providing the storage recess 34 that stores the stand member 21 in the storage position with the protruding portion 36 that protrudes toward the inner surface of the stand member 21, the stand member 21 and the left floor side cover 11eL are closer together in the stand-stored state, reducing the gap between the stand member 21 and the left floor side cover 11eL and improving the appearance. The storage recess 34 is concave when viewed from outside the vehicle, but even if a structure such as the body frame 16 is present behind the storage recess 34, the protruding portion 36 covers the structure, hiding it and improving the appearance in the stand-up state, while also ensuring a gap between the structure and the left floor side cover 11eL and reducing interference between vehicle parts.
[0051] In the above-described side stand structure, at least the end (top 36c) of the protruding portion 36 on the inner surface 23b side is close to a virtual area obtained by extending the rotation area R1 of the stand member 21 in the circumferential direction, and the end (top 36c) of the protruding portion 36 is located lower than the connection portion 23 of the stand member 21 in the storage position in the vertical direction of the vehicle. According to this configuration, the end portion (top 36c) of the protruding portion 36 on the inner surface of the stand is close to the extension portion 24b of the rotation area R1 of the stand member 21, and by positioning the top 36c of the protruding portion 36 below the connection portion 23, it is possible to position the raised portion 26 above the top 36c of the protruding portion 36, and space can be efficiently secured to avoid the raised portion 26, allowing the stand member 21 to be stored.
[0052] The present invention is not limited to the above-described embodiment. For example, the side stand structure of the present embodiment may be applied to saddle-ride type vehicles other than motorcycles, as long as the vehicle is equipped with a side stand. The saddle-type vehicle includes all vehicles on which the driver straddles the body, including not only motorcycles (including motorized bicycles and scooter-type vehicles), but also three-wheeled vehicles (including vehicles with one front wheel and two rear wheels, as well as vehicles with two front wheels and one rear wheel) or four-wheeled vehicles (such as four-wheeled buggies). The configurations in the above-described embodiments are merely examples of the present invention, and various modifications are possible within the scope of the gist of the present invention, such as replacing the components of the embodiments with well-known components.
