Summary of the invention

Problems to be solved by the invention

However, since the side frames support the vehicle body in an inclined state, the above-described conventional technique has the following problems. That is, a side stand bracket or the like that rotatably supports the side stand protrudes outward in the vehicle width direction below the vehicle body lower portion. Therefore, when the vehicle body is largely tilted at the time of turning, or when the vehicle body passes over a rough road surface, or the like, the following possibility exists. That is, peripheral components such as the jiffy stand bracket may be unintentionally grounded. Therefore, the side frames are required to be more compact in the periphery.

Therefore, the present invention provides a side stand structure capable of achieving a compact side stand periphery.

Means for solving the problems

As a solution to the above problem, a first aspect of the present invention is a side stand structure including a side stand (20) rotatably supported by a vehicle body (11) and a stand switch (40) for detecting a rotational position of the side stand (20), wherein the side stand structure includes: a rotation positioning portion (45) that positions the parking frame switch (40) in a rotation direction of the side parking frame (20); and a connector unit (46) that connects the wire harness (H) to the parking frame switch (40), wherein a first straight line (T1) that connects an axial center (p1) of a rotating shaft (35) of the side parking frame (20) and a positioning center (p2) of the rotational positioning unit (45) extends from the rotating shaft (35) side to the rotational positioning unit (45) side in the front-rear direction of the vehicle in a side view of the vehicle, and a second straight line (T2) that extends in the wire attaching/detaching direction of the connector unit (46) extends from the rotating shaft (35) side to the connector unit (46) side in the front-rear direction of the vehicle in a side view of the vehicle.

A second aspect of the present invention is the first aspect, wherein the first straight line (T1) extends from the rotational shaft (35) side to the rotational position determining portion (45) side toward the front in the vehicle longitudinal direction in a vehicle side view, and the second straight line (T2) extends from the rotational shaft (35) side to the connector portion (46) side toward the rear in the vehicle longitudinal direction in a vehicle side view.

A third aspect of the present invention is the side stand according to the second aspect, wherein the side stand (20) includes a pivot portion (22) rotatably coupled to the vehicle body (11), and an inner side surface (46d) of the connector portion (46) on the vehicle width direction inner side is disposed apart from an outer side surface (22d) of the pivot portion (22) on the vehicle width direction outer side in the axial direction of the rotating shaft (35).

A fourth aspect of the present invention is any one of the first to third aspects, wherein the rotation positioning portion (45) is disposed at a front upper side of the rotation shaft (35) in a vehicle side view, the connector portion (46) is disposed at a rear upper side of the rotation shaft (35), the connector portion (46) is capable of attaching and detaching the wire harness (H) along an axis (C3) having a low front and a high rear, a straight line connecting an axial center (p1) of the rotation shaft (35) and an axial center (p2) of a positioning pin (34) provided on the vehicle body (11) side of the rotation positioning portion (45) is set as the first straight line (T1) in the vehicle side view, and a straight line along the axis (C3) of the connector portion (46) is set as the second straight line (T2) in the vehicle side view, the second straight line (T2) is set as the vehicle side view with respect to a vertical line (T3) passing through an axial center (p1) of the rotation shaft (35) The backward inclination angle (theta 2) is set smaller than the forward inclination angle (theta 1) of the first straight line (T1) with respect to the vertical line (T3).

A fifth aspect of the present invention is any one of the first to fourth aspects, wherein a jiffy stand bracket (30) that rotatably supports the side jiffy stand (20) and a frame member (14) that fixes the jiffy stand bracket (30) are provided on the vehicle body (11) side, and the frame member (14) includes a recess (18a) that overlaps at least a part of the connector portion (46) in a side view of the vehicle.

A sixth aspect of the present invention is any one of the first to fourth aspects, wherein the connector portion (46) includes a locking portion (46a) that locks the connector portion (46) in a coupled state, and an unlocking portion (46b) that performs an unlocking operation of the locking portion (46a), and the unlocking portion (46b) is disposed on an inner side of the connector portion (46) in the vehicle width direction.

Effects of the invention

According to the first aspect, the first straight line extending from the turning shaft side to the turning positioning portion side extends toward the front-rear direction of the vehicle in a side view of the vehicle. In a side view of the vehicle, a second straight line extending from the rotating shaft side to the connector portion side extends toward the other of the front and rear in the vehicle front-rear direction. Thus, the pivot positioning portion of the side stand and the connector portion are disposed apart from each other in the front-rear direction of the vehicle with respect to the pivot shaft of the side stand, and therefore, the following effects are obtained. That is, the parking frame switch can be disposed closer to the vehicle body in the vehicle width direction and the vertical direction than in the case where both the rotation positioning portion protruding to the outer peripheral side of the parking frame switch and the connector portion are disposed closer to one side of the rotating shaft in the vehicle longitudinal direction. Therefore, the periphery of the side stand can be made compact, and unintended grounding of the side stand can be easily avoided by moving the side stand upward.

According to the second aspect described above, the first straight line extends toward the front of the vehicle and the second straight line extends toward the rear of the vehicle in a side view of the vehicle. In this way, the rotation positioning portion is disposed in front of the rotation shaft, and the connector portion is disposed behind the rotation shaft, so that the positioning pin or the like provided on the vehicle body side of the rotation positioning portion is disposed in front of the rotation shaft. In general, the side parking frame is rotated between a use position extending downward from the rotation shaft and a storage position extending rearward. Therefore, by disposing the rotation positioning portion in front of the rotation shaft, the positioning pin and the like are retracted from the rotation range of the side stand. Thus, the pivot positioning portion and the connector portion can be disposed apart in the vehicle front-rear direction without obstructing the pivot range of the side stand. Further, since the connector section as the electrical component is disposed toward the rear, the waterproof property and the dustproof property of the connector section can be improved.

According to the third aspect, since the connector portion is disposed so as to be separated outward in the vehicle width direction of the pivot portion, it is possible to reliably avoid interference between the side stand and the connector portion when the side stand is rotated.

According to the fourth aspect, since the rearward inclination angle of the second straight line on the connector portion side is set smaller (i.e., nearly vertical) than the forward inclination angle of the first straight line on the rotational positioning portion side, it is easy to extend the wiring extending from the connector portion upward (toward the vehicle body side), and it is possible to improve the wiring layout property and to shorten the wiring.

According to the fifth aspect, since the frame member includes the recess portion that overlaps the connector portion, the side stand can be brought close to the frame member including the connector portion. Therefore, the side frames can be made compact in the periphery, and the grounding of the side frames can be easily avoided by moving the side frames upward.

According to the sixth aspect, since the unlocking operation portion of the connector portion is disposed on the inside of the connector portion in the vehicle width direction, it is possible to suppress an improper operation on the connector portion, and the unlocking operation portion is disposed so as to be less visible from the outside in the vehicle width direction, thereby improving the appearance.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. The directions such as front, rear, left, right, and the like in the following description are the same as those in the following vehicle unless otherwise noted. In the drawings used in the following description, arrow FR indicating the front of the vehicle, arrow LH indicating the left of the vehicle, and arrow UP indicating the upper side of the vehicle are shown at appropriate positions.

< vehicle entirety >

Fig. 1 shows a motorcycle (scooter type vehicle) 1 of a unit swing type as an example of a saddle type vehicle according to the present embodiment. The motorcycle 1 includes a front wheel 3 as a steering wheel and a rear wheel 4 as a driving wheel. The front wheel 3 is supported by a pair of left and right front forks 6 and can be steered by the handlebar 2. The rear wheel 4 is supported by a swing unit (power unit) U and can be driven by an engine E.

The swing unit U supports the rear wheel 4 as a driving wheel so as to be swingable up and down. The swing unit U integrally includes an engine (internal combustion engine) E as a drive source and a continuously variable transmission M of, for example, a V-belt type. A rear wheel 4 is supported by an output shaft at the rear of the continuously variable transmission M. The rear portion of the continuously variable transmission M is supported by the frame 11 via the rear cushion 7.

Steering system components including the handlebar 2, the left and right front forks 6, and the front wheel 3 are supported by a head pipe 12 at the front end of the frame 11 so as to be able to steer. The swing unit U and the rear wheel 4 are supported by a pivot portion (not shown) at the lower portion of the vehicle body frame 11 via a suspension link or the like so as to be able to swing up and down.

The front part of the vehicle body is covered with a front cover 8, and the rear part of the vehicle body is covered with a rear cover 9. Between the front cover 8 and the rear cover 9 is a low floor portion 10. A bottom pedal 10a for placing a foot of the driver is provided on an upper surface portion of the low floor portion 10. A seat 5 on which an occupant including a driver sits is supported above the rear cover 9. In the figure, reference numeral 10b denotes a pair of left and right floor side covers that are turned around below the left and right side edges of the floor panel 10 a.

The vehicle body frame 11 includes: a head pipe 12 at a front end portion; a down frame 13 extending downward from the head pipe 12; a pair of right and left lower frames 14 extending by bending rearward from the lower end of the down frame 13; and a pair of right and left rear frames 15 extending from the rear end of the lower frame 14 while being bent upward and rearward. The pivot portion that supports the front end portion of the swing unit U is provided near the rear end portions of the left and right under frames 14.

< side jiffy stand >

As shown in fig. 1, a tiltable side stand 20 is attached to a left lower frame (frame member) 14 of a frame 11. The side stand 20 supports the body of the motorcycle 1 in an upright state inclined to the left.

As shown in fig. 2 to 5, the side frames 20 are rotatably supported by a frame bracket 30 fixed to the left lower frame 14. The side frames 20 are rotatable between a storage position where the front end side (ground side) is sprung to the rear of the turning shaft 35 (shown by a central axis C1) and a use position (standing position) where the front end side extends downward of the turning shaft 35. In the figure, the side jiffy stand 20 in the use position is indicated by a chain line.

The side jiffy stand 20 integrally includes: a parking frame rod 21 made of, for example, a straight steel pipe; a pivot portion 22 provided at one end side (base end side, turning shaft 35 side) of the parking lever 21 and turnably connected to the vehicle body side; and a grounding portion 23 provided on the other end side (front end side, grounding side) of the parking lever 21 and forming a grounding surface for supporting the vehicle body.

The pivot portion 22 is formed in a bifurcated shape that sandwiches a flat-plate-shaped parking frame connecting portion 31a of the parking frame bracket 30 in the plate thickness direction. The pivot portion 22 includes a pair of two plate portions 22a, 22 b. The two plate portions 22a and 22b are provided in parallel with each other with an interval in the plate thickness direction of the parking frame connecting portion 31 a. A groove 22c into which the jiffy stand coupling portion 31a is relatively rotatably inserted is formed between the two plate portions 22a and 22 b. Shaft insertion holes 22a1, 22b1 (see fig. 5) through which the rotating shaft 35 passes are formed coaxially with each other in the both plate portions 22a, 22 b.

The parking frame coupling portion 31a of the parking frame bracket 30 is inserted into the groove portion 22c of the pivot portion 22 of the side parking frame 20. In this state, the pivot shaft 35 penetrating the pivot shaft portion 22 and the parking frame connecting portion 31a is attached. Thereby, the side stand 20 is rotatably coupled to and supported by the stand bracket 30 via the rotating shaft 35.

The pivot shaft 35 is inclined upward so as to be positioned further upward toward the vehicle width direction outer side. Thus, when the side stand 20 is at the standing position, the side stand 20 is extended outward in the vehicle width direction. Further, when the side frames 20 are in the storage position, the side frames 20 are prevented from protruding outward in the vehicle width direction. The side frames 20 in the standing position protrude outward in the vehicle width direction, and the following effects are obtained. That is, the ground contact portion 23 is easily arranged on the outer side in the vehicle width direction to support the vehicle body of the motorcycle 1. The following effects are obtained by suppressing the extension of the side jiffy stand 20 at the storage position to the outside in the vehicle width direction. That is, when the vehicle body is tilted, the side frames 20 are difficult to be grounded. The pivot shaft 35 is also inclined in the front-rear direction so as to be positioned further forward as it goes further outward in the vehicle width direction. The center axis of the rotating shaft 35 is indicated by a line C1.

The side frames 20 and their peripheral components are sometimes unintentionally grounded. This ground contact occurs when the vehicle body is largely tilted during cornering, when the vehicle body passes over irregularities on a road surface, or the like. In order to suppress the influence of the side stand 20 on the inclination angle of the vehicle body and the minimum ground clearance, the mounting position of the side stand 20 is preferably located as upward as possible.

A locking hook 26 for locking one end of a parking frame spring (tension coil spring) 25 is provided on the front end side of the side parking frame 20. The locking hook 26 protrudes outward in the vehicle width direction from the longitudinal direction intermediate portion of the parking lever 21, and then is bent toward the front end side of the parking lever 21. The locking hook 26 is bent toward the front end of the parking lever 21, then linearly extends to the grounding portion 23, and the front end portion is welded to the grounding portion 23. An extension portion of the locking hook 26 to the grounding portion 23 extends outward in the vehicle width direction of the front end side of the parking lever 21, thereby serving as a step portion 26 a. The foot support portion 26a enables the turning operation of the side stand 20 by the foot of the user.

< jiffy stand mounting part >

As shown in fig. 4, at least the left lower frame 14 of the vehicle frame 11 is a press frame. The press frame is formed by integrally combining a plurality of press frame bodies. The left lower frame 14 includes an outer frame body 16a on the vehicle width direction outer side and an inner frame body 16b on the vehicle width direction inner side. The frame bodies 16a and 16b are each formed by, for example, pressing a steel plate. The frame bodies 16a and 16b are joined to each other by spot welding or the like with joining flanges 16a1 and 16b1 provided on the outer peripheral portions or the like. Thus, the two frame bodies 16a, 16b form the left lower frame 14 of a closed cross-sectional structure.

A parking frame mounting portion 18 for mounting a side parking frame is provided on the left lower frame 14. The jiffy stand mounting portion 18 includes a reinforcing bracket 19 welded and fixed to the left lower frame 14, and a jiffy stand bracket 30 welded and fixed to the reinforcing bracket 19. In the present embodiment, the reinforcing bracket 19 and the parking frame bracket 30 are included in the structure of the vehicle body frame 11.

The reinforcing bracket 19 is formed in a substantially V-shape when viewed in the front-rear direction so as to straddle the left lower frame 14 from below. The reinforcing bracket 19 includes an outer plate 19a, an inner plate 19b, and an inclined plate 19 c. The outer plate portion 19a is disposed along and joined to the outer surface of the left lower frame 14 on the vehicle width direction outer side. The inner plate portion 19b is disposed along and joined to the inner surface of the left lower frame 14 on the vehicle width direction inner side. The inclined plate portion 19c extends obliquely below the outer plate portion 19a toward the bracket lower end portion 19d so as to be located further inward in the vehicle width direction as going downward.

The bracket lower end portion 19d is U-shaped when viewed in the front-rear direction. The lower end portion of the inner plate portion 19b is connected to the upper end portion of the bracket lower end portion 19d on the vehicle width direction inner side. The lower end portion of the inclined plate portion 19c is connected to the upper end portion of the bracket lower end portion 19d on the outer side in the vehicle width direction.

Referring to fig. 2 and 3 together, the portion of the left lower frame 14 to which the reinforcing bracket 19 is joined is the portion of the outer frame 16a to which the outer plate portion 19a is joined. At this portion, a joint (hereinafter, referred to as a recessed portion 18a) is formed in which the outer surface changes inward in the vehicle width direction. The recess 18a is located at a position overlapping with a connector portion 46 described later in a vehicle side view. The recessed portion 18a is also a avoiding portion that avoids the inside of the connector portion 46 in the vehicle width direction.

Referring to fig. 4 and 5, the parking frame bracket 30 includes: a bracket base 32 joined to the reinforcing bracket 19; and a linking plate 31 joined to and held by the bracket base 32 and forming a jiffy stand linking portion 31 a.

The bracket base 32 includes a joint plate portion 32a and a front end plate portion 32 b. The joint plate portion 32a is bent so as to extend along the outer side surfaces of the inclined plate portion 19c and the bracket lower end portion 19d of the reinforcing bracket 19 on the outer sides in the vehicle width direction. The front end plate portion 32b extends from the front end of the joint plate portion 32a toward the vehicle width direction outer side, and is bent downward in a direction orthogonal to the inclined plate portion 19 c. The front end plate portion 32b extends to the outside in the vehicle width direction of a below-described parking frame switch 40, and suppresses the influence of interference from the outside in the vehicle width direction to the periphery of the parking frame switch 40.

The connecting plate 31 is disposed so as to be orthogonal to the inclined plate portion 19 c. The linking plate 31 is inclined such that both surfaces in the plate thickness direction are positioned lower as going outward in the vehicle width direction. The link plate 31 forms a jiffy stand coupling portion 31a that fits into the pivot portion 22 of the side jiffy stand 20. The linking plate 31 is formed of a steel plate thicker than the bracket base 32. The bracket base 32 is formed of a steel plate thicker than the reinforcing bracket 19. The reinforcing bracket 19 is formed of a steel plate thicker than the outer frame 16a and the inner frame 16 b.

The parking rack mounting portion 18 is not limited to the above-described structure. For example, the following structure is possible: the frame 11 is made of a steel pipe, or the jiffy stand bracket 30 is an integral member, or the jiffy stand bracket 30 is detachably fixed to the frame 11 by fastening with a bolt or the like.

The jiffy stand coupling portion 31a has a shaft insertion hole 31b (see fig. 5) formed in a substantially central portion in a plan view so as to penetrate in the plate thickness direction. The shaft insertion hole 31b is arranged as follows in a state where the coupling plate 31 is inserted into the groove portion 22c of the pivot portion 22. The shaft insertion hole 31b is disposed coaxially with the shaft insertion holes 22a1, 22b1 provided in the pair of plate portions 22a, 22b of the pivot portion 22.

As shown in fig. 5, the pivot shaft 35 is configured as a so-called stepped bolt 36. The shoulder bolt 36 is inserted into or removed from the respective insertion holes 22a1, 22b1, 31b of the pivot portion 22 and the jiffy stand coupling portion 31a from the outside in the vehicle width direction. The stepped bolt 36 includes: a head portion 36a located on the vehicle width direction outer side; a shaft portion 36b connected to the vehicle width direction inner side of the head portion 36 a; and a threaded shaft 36c projecting inward in the vehicle width direction of the pivot portion 22.

The shaft insertion hole 22a1 of the plate portion 22a on the vehicle width direction outer side of the pivot portion 22 and the shaft insertion hole 31b of the jiffy stand coupling portion 31a have the same diameter. The shaft portion 36b of the stepped bolt 36 can be inserted into the shaft insertion holes 22a1, 31 b. The shaft insertion hole 22b1 of the plate portion 22b on the vehicle width direction inner side of the pivot portion 22 is set to the following diameter. The shaft insertion hole 22b1 is smaller in diameter than the respective shaft insertion holes 22a1, 31b of the vehicle width direction outer plate portion 22a of the pivot portion 22 and the jiffy stand connecting portion 31 a. The shaft insertion hole 22b1 allows the threaded shaft 36c of the stepped bolt 36 to pass through, but does not allow the shaft portion 36b to pass through. The peripheral edge portion of the shaft insertion hole 22b1 on the vehicle width direction outer side (the side of the jiffy stand coupling portion 31 a) serves as a seat surface against which the tip end surface of the shaft portion 36b abuts. The shaft portion 36b is larger in diameter than the threaded shaft 36 c.

When the side stand 20 is assembled, the shaft portion 36b of the stepped bolt 36 passes through the plate portion 22a on the vehicle width direction outer side of the pivot portion 22 and the shaft insertion holes 22a1, 31b of the stand connecting portion 31 a. At this time, the shaft portion 36b has the front end surface in contact with the peripheral edge portion of the shaft insertion hole 22b1 of the inner plate portion 22b in the vehicle width direction. In this state, the nut 37 is screwed into the threaded shaft 36c protruding inward in the vehicle width direction of the pivot portion 22. Thereby, the shoulder bolt 36 is fixed to the inner plate portion 22b in the vehicle width direction. Thus, the pivot portion 22 is rotatably supported and coupled to the parking frame coupling portion 31a via the stepped bolt 36.

Referring to fig. 2 to 4, a stepped front lower stopper 33a defining the rising position of the side stand 20 is formed at the front lower portion of the connecting plate 31. The front lower limit movement portion 33a is configured to allow one end side in the rotation direction of the pivot portion 22 to abut from behind to define the rising position of the side stand 20. A stepped rear upper stopper 33b that defines the storage position of the side jiffy stand 20 is formed at the rear upper portion of the coupling plate 31. The rear upper stopper portion 33b defines the storage position of the side stand 20 by the other end side of the pivot portion 22 in the rotational direction coming into contact from below.

A locking pin 34 for locking the other end of the parking frame spring (tension coil spring) 25 is provided in a protruding manner on the front upper portion of the link plate 31. The locking pin 34 is provided parallel to the rotation shaft 35, for example. The jiffy stand spring 25 is provided in tension between the locking hook 26 of the side jiffy stand 20 and the locking pin 34 of the jiffy stand coupling portion 31 a. The parking frame spring 25 holds the rotational position of the side parking frame 20 at the standing position or the storage position by its own tension. Line C2 represents the center axis of the latch pin 34.

< parking frame switch >

As shown in fig. 2 to 5, a parking frame switch 40 that detects the turning position of the side parking frame 20 is provided on the vehicle width direction outer side of the pivot portion 22.

The parking stand switch 40 is a rotary switch provided coaxially with the rotary shaft 35. The parking frame switch 40 detects whether the side parking frame 20 is in the use position or the storage position and outputs a corresponding electric signal. The electric signal is sent to an engine control unit, not shown, and used for various controls. This control is, for example, control for disabling the engine E from starting when the side stand 20 is in the use position while the engine E is stopped. The control is performed, for example, to stop the engine E when the side stand 20 is rotated from the storage position to the use position during the operation of the engine E.

Referring to fig. 5, the parking frame switch 40 includes a rotor 41 and a housing 42. The rotor 41 is provided to be rotatable integrally with the side stand 20. The housing 42 accommodates the rotor 41 and is provided to be rotatable relative to the side frames 20.

The rotor 41 is disposed on the vehicle width direction outer side of the head portion 36a of the stepped bolt 36. The rotor 41 is capable of passing through a switch mounting bolt 43 coaxial with the stepped bolt 36. The switch mounting bolt 43 penetrates the rotor 41 and is screwed into a screw hole 36d penetrating the head portion 36a side of the stepped bolt 36. Thereby, the rotor 41 can rotate integrally with the stepped bolt 36 and the side jiffy stand 20.

Referring also to fig. 3, the housing 42 has a circular shape as viewed in the axial direction of the rotating shaft 35. The housing 42 is in a cup shape covering the rotor 41 from the outside in the vehicle width direction. The housing 42 is close to the plate portion 22a disposed on the vehicle width direction outer side of the pivot portion 22 via a thrust washer 42a or the like. In this state, the housing 42 is restricted from being removed outward in the vehicle width direction by the large-diameter washer 43a used on the seat surface of the switch mounting bolt 43. Thereby, the housing 42 is mounted on the vehicle width direction outer side of the pivot portion 22.

The locking pin 34 that locks the parking frame spring 25 is positioned at the front upper side of the housing 42. A locking claw portion 42b is provided in a front upper portion of the housing 42 so as to protrude toward an outer peripheral side (radially outer side) of the housing 42. The locking claw portion 42b forms a U-shaped locking groove 42c that opens to the outer peripheral side of the housing 42. The locking groove 42c can engage the locking pin 34. The locking claw portion 42b and the locking pin 34 constitute a turning positioning portion 45 that positions the housing 42 in the turning direction of the side stand 20.

Referring to fig. 4 and 5, the symbols p1 and p2 indicate the following intersections. The intersection point is an intersection point between the center axes C1, C2 of the pivot shaft 35 and the locking pin 34 and the vehicle width direction outer side surface (a plane orthogonal to the pivot shaft 35) of the linking plate 31. For example, the intersection point is defined as the respective axial centers p1, p2 of the rotating shaft 35 and the locking pin 34.

Referring to fig. 6, a straight line connecting the axial center p1 of the rotating shaft 35 and the axial center p2 of the locking pin 34 in a side view of the vehicle is defined as a first straight line T1. The axial center p2 corresponds to the positioning center of the rotation positioning portion 45.

Referring to fig. 2 and 3, a connector 46 is disposed at the upper rear of the housing 42. The connector portion 46 can connect an electric wire (harness) H extending from the vehicle body side to the parking frame switch 40. The connector portion 46 includes a terminal portion 47 and a coupler 48. Terminal portions 47 are provided at the rear upper portion of case 42 so as to protrude toward the outer peripheral side of case 42. The terminal portion 47 of the coupler 48 is inserted from the outer peripheral side of the housing 42 and fitted to the outside. A line C3 in fig. 3 indicates a center axis in the connector portion 46 in the insertion and extraction direction (wiring attachment and detachment direction) of the coupling 48. The insertion and extraction direction of the coupling 48 is a direction parallel to a plane orthogonal to the rotation shaft 35.

Referring to fig. 6, a straight line along the center axis C3 in the vehicle side view is defined as a second straight line T2.

Referring to fig. 2 and 6, the pivot positioning portion 45 and the connector portion 46 are disposed as follows with respect to the pivot shaft 35 of the side stand 20 in a side view of the vehicle. That is, the rotation positioning portion 45 and the connector portion 46 are disposed apart in the front-rear direction of the vehicle. The pivot positioning portion 45 is disposed forward of the pivot shaft 35 in a side view of the vehicle. The connector 46 is disposed rearward of the rotating shaft 35. A line T3 in fig. 6 indicates a vertical line passing through the axial center p1 of the rotating shaft 35 in a side view of the vehicle.

In a side view of the vehicle, a straight line connecting the axial center p1 of the rotating shaft 35 and the positioning center p2 of the rotation positioning portion 45 is defined as a first straight line T1. The first straight line T1 extends obliquely upward and forward from the rotational shaft 35 side to the rotational positioning portion 45 side. In a vehicle side view, a straight line along the wiring attachment/detachment direction (center axis C3) of the connector portion 46 is defined as a second straight line T2. The second straight line T2 extends obliquely rearward and upward from the rotation shaft 35 side to the connector portion 46 side. In a side view of the vehicle, the first straight line T1 and the second straight line T2 are arranged in a V shape so as to intersect each other at a relative angle.

In the present embodiment, the pivot positioning portion 45 is disposed toward the vehicle front side and the connector portion 46 is disposed toward the vehicle rear side with reference to the pivot shaft 35 of the parking stand switch 40. That is, the pivot positioning portion 45 and the connector portion 46 of the parking frame switch 40 are disposed in a dispersed manner in the vehicle front-rear direction. This can shorten the distance between the parking rack switch 40 and the vehicle body frame 11. Therefore, the periphery of the side stand 20 can be made compact. The following effects are obtained by bringing the side frames 20 close to the vehicle body (displacing them upward). That is, when the vehicle body is tilted, the side frames 20 are difficult to be grounded, and the minimum ground clearance is easily secured.

In the present embodiment, the rearward inclination angle θ 2 of the second straight line T2 with respect to the vertical line T3 passing through the axial center p1 of the rotating shaft 35 in the vehicle side view is set as follows. That is, the inclination angle θ 2 is set smaller (i.e., closer to vertical) than the forward inclination angle θ 1 of the first straight line T1 with respect to the vertical line T3. This makes it easy to extend the wiring H extending from the connector portion 46 upward (toward the vehicle body). Therefore, the layout of the wiring H can be improved and the wiring H can be shortened.

Referring to fig. 4, in the present embodiment, the vehicle width direction inside inner surface 46d of the connector portion 46 is positioned further outward in the vehicle width direction than the vehicle width direction outside outer surface 22d of the pivot portion 22 in the axial direction of the rotating shaft 35. That is, the connector portion 46 is offset outward in the vehicle width direction in the axial direction of the rotating shaft 35 with respect to the housing 42. In the axial direction of the rotary shaft 35, the center axis C3 of the connector portion 46 is offset outward in the vehicle width direction with respect to the height center (indicated by a line T4) of the housing 42. In the axial direction of the rotating shaft 35, the inner side surface 46d of the connector portion 46 on the vehicle width direction inner side is separated from the outer side surface 22d of the pivot portion 22 on the vehicle width direction outer side by a gap k.

In the present embodiment, the inner side surface 46d of the connector portion 46 on the vehicle width direction inner side is disposed on the vehicle width direction outer side than the outer side surface 22d of the pivot portion 22 of the side stand 20 on the vehicle width direction outer side in the axial direction (turning shaft direction) of the turning shaft 35 of the side stand 20. Thus, even if the connector portion 46 is positioned so as to overlap the range of rotation of the pivot portion 22 when viewed in the direction of the axis of rotation, interference between the rotating pivot portion 22 and the connector portion 46 can be avoided.

As shown in fig. 7, the connector portion 46 of the parking frame switch 40 includes a lock portion 46 a. The locking portion 46a restricts the disengagement of the coupler 48 from the terminal portion 47 in a connected state in which the terminal portion 47 and the coupler 48 are fitted to each other. The connector portion 46 includes a lock release operation portion 46b that enables a release operation of the lock portion 46a for restricting disengagement of the coupling 48. The lock release operation portion 46b is disposed on the vehicle width direction inner side of the connector portion 46.

As described above, the side stand structure according to the above embodiment includes: a side stand 20 rotatably supported by a vehicle body (frame 11); a jiffy stand switch 40 that detects the rotational position of the side jiffy stand 20; a rotation positioning portion 45 that positions the parking frame switch 40 in a rotation direction of the side parking frame 20; and a connector portion 46 for connecting the wiring H to the parking frame switch 40. The pivot positioning portion 45 and the connector portion 46 are disposed apart from each other in the front-rear direction of the vehicle with respect to the pivot shaft 35 of the side stand 20.

According to this configuration, since the pivot positioning portion 45 of the side stand 20 and the connector portion 46 are disposed apart from each other in the front-rear direction of the vehicle with respect to the pivot shaft 35 of the side stand 20, the following effects are exhibited. That is, the parking frame switch 40 can be disposed closer to the vehicle body in the vehicle width direction and the vertical direction than in the case where both the pivot positioning portion 45 protruding to the outer peripheral side of the parking frame switch 40 and the connector portion 46 are disposed offset to one side of the pivot shaft 35 in the vehicle longitudinal direction. Therefore, the periphery of the side stand 20 can be made compact, and unintended grounding of the side stand 20 can be easily avoided by the upward movement of the side stand 20.

In the side stand structure, the pivot positioning portion 45 is disposed forward of the pivot shaft 35 of the side stand 20, and the connector portion 46 is disposed rearward.

According to this configuration, since the pivot positioning portion 45 is disposed in front of the pivot shaft 35 and the connector portion 46 is disposed behind the pivot shaft 35, the engagement pin 34 and the like provided on the vehicle body side of the pivot positioning portion 45 are disposed in front of the pivot shaft 35. Normally, the side frames 20 are rotated between a use position extending downward from the rotation shaft 35 and a storage position extending rearward. Therefore, by disposing the pivot positioning portion 45 in front of the pivot shaft 35, the locking pin 34 and the like are retracted from the pivot range of the side jiffy stand 20. Thus, the pivot positioning portion 45 and the connector portion 46 can be disposed apart in the vehicle front-rear direction without obstructing the pivot range of the side stand 20. Further, since the connector portion 46 as the electrical component is disposed toward the rear, the waterproof property and the dustproof property of the connector portion 46 can be improved.

In the side stand structure, the side stand 20 includes a pivot portion 22 pivotably coupled to the vehicle body, and an inner surface 46d of the connector portion 46 on the vehicle width direction inner side is disposed apart from an outer surface 22d of the pivot portion 22 on the vehicle width direction outer side in the axial direction of the pivot shaft 35.

According to this configuration, since the connector portion 46 is disposed apart from the pivot portion 22 to the outside in the vehicle width direction, it is possible to reliably avoid interference between the side stand 20 and the connector portion 46 when the side stand 20 is rotated.

In the side jiffy stand structure, the pivot positioning portion 45 is disposed in front of and above the pivot shaft 35 in a side view of the vehicle, the connector portion 46 is disposed rearward and upward of the pivot shaft 35, the connector portion 46 is configured to be able to attach and detach the wiring H along an axis line C3 with a low front and a high rear in a vehicle side view, in a side view of the vehicle, a straight line connecting the axial center p1 of the rotating shaft 35 and the axial center p2 of the locking pin 34 of the pivot positioning portion 45 on the vehicle body side is defined as a first straight line T1, when a straight line along the axis C3 of the connector portion 46 is defined as a second straight line T2 in a side view of the vehicle, in a side view of the vehicle, an inclination angle θ 2 of the second straight line T2 to the rear with respect to a vertical line T3 passing through an axial center p1 of the rotating shaft 35 is set smaller than an inclination angle θ 1 of the first straight line T1 to the front with respect to the vertical line T3.

According to this configuration, since the rearward inclination angle θ 2 of the second straight line T2 on the connector portion 46 side is set smaller (i.e., closer to vertical) than the forward inclination angle θ 1 of the first straight line T1 on the rotational positioning portion 45 side, the wiring H extending from the connector portion 46 can be easily extended upward (toward the vehicle body side), and the layout of the wiring H can be improved and shortened.

In the side stand structure, a stand bracket 30 that rotatably supports the side stand 20 and a lower frame 14 that fixes the stand bracket 30 are provided on the vehicle body side, and the lower frame 14 includes a recess 18a that overlaps at least a part of the connector portion 46 in a vehicle side view.

According to this configuration, since the lower frame 14 includes the recess 18a overlapping the connector portion 46, the side frames 20 can be brought close to the lower frame 14 including the connector portion 46. Therefore, the periphery of the side stand 20 can be made compact, and the side stand 20 can be easily prevented from being grounded by moving upward the side stand 20.

In the side-stand structure, the connector portion 46 includes a lock portion 46a that locks the connector portion 46 in a coupled state, and an unlocking operation portion 46b that performs an unlocking operation of the lock portion 46a, and the unlocking operation portion 46b is disposed on the inside of the connector portion 46 in the vehicle width direction.

According to this configuration, since the unlocking operation portion 46b of the connector portion 46 is disposed on the vehicle width direction inner side of the connector portion 46, it is possible to suppress an improper operation on the connector portion 46, and the unlocking operation portion 46b is disposed so as to be less visible from the vehicle width direction outer side, thereby improving the appearance.

The present invention is not limited to the above embodiments. For example, the vehicle body to which the side stand is attached is not limited to the vehicle frame, and may be a structure attached to the vehicle frame or a power unit such as an engine. The rotation positioning portion may be disposed behind the rotating shaft and the connector portion may be disposed in front of the rotating shaft. The rotational positioning portion may be configured such that the positioning pin is disposed on the parking frame switch side and the pin engaging portion is disposed on the vehicle body side.

The vehicle to which the present invention is applied includes all vehicles having side frames. That is, the present invention includes not only motorcycles (including bicycles and scooter-type vehicles with a prime mover), but also three-wheeled vehicles (including front and rear two-wheeled vehicles as well as front and rear two-wheeled vehicles) or four-wheeled vehicles, and also includes vehicles in which the prime mover includes an electric motor.

The configuration in the above embodiment is an example of the present invention, and the components of the embodiment may be replaced with known components, and various modifications may be made without departing from the scope of the present invention.
