Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional configuration, since vehicle components such as the bracket for supporting the side stand and the side stand are located outside the vehicle width direction of the lower frame, it has been difficult to suppress an increase in the vehicle width due to the vehicle components. In particular, for vehicle components having a length such as a side stand, since the entire vehicle component is located outside the vehicle width direction of the lower frame, it has been difficult to suppress an increase in the vehicle width unless the vehicle component is miniaturized. The present invention has been made in view of the above circumstances, and an object thereof is to enable vehicle components to be compactly arranged in the vehicle width direction even if the vehicle components are long in the vehicle front-rear direction.

Means for Solving the Problems

[0005] In a saddle-riding type vehicle including a lower frame and a curved portion extending upward from the lower frame, the curved portion has a recess recessed inward in the vehicle width direction, the recess continuously extends to the rear end of the curved portion, and at least a part of vehicle components of the vehicle is disposed in the recess. The lower frame is a pair on the left and right, each of the pair of left and right curved portions has the concave portion, a part of the stand is arranged in one of the concave portions, and a part of the canister is arranged in the other concave portion. A saddle-riding type vehicle is provided.

Advantages of the Invention

[0006] Even if the vehicle component is a component that is long in the vehicle front-rear direction, the vehicle component can be arranged compactly in the vehicle width direction.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description, the descriptions of directions such as front, rear, left, right, up, and down are the same as the directions with respect to the vehicle unless otherwise specified. In each figure, the reference sign FR indicates the front of the vehicle, the reference sign UP indicates the upper side of the vehicle, and the reference sign LH indicates the left side of the vehicle.

[0009] [Embodiment] FIG. 1 is a side view of a straddle-type vehicle 10 according to an embodiment of the present invention. In FIG. 1, for convenience of explanation, a body cover 100, a vehicle seat 101, etc. are shown by a two-dot chain line. The straddle-type vehicle 10 is a scooter-type motorcycle in which a power unit 12 for driving a rear wheel 13R is connected to the rear part of a vehicle body frame 11 so as to be swingable vertically. The power unit 12 is also referred to as a unit swing engine or the like, and in the present embodiment, it is a power unit having an internal combustion engine, that is, a configuration in which rear-wheel driving force is obtained by the internal combustion engine. In the present invention, the power unit 12 is not limited to a configuration having an internal combustion engine, and a known power unit can be widely applied. For example, a configuration having a drive motor may also be used.

[0010] The vehicle body frame 11 includes a head pipe 21, a down frame 22 extending rearward and downward from the head pipe 21, a pair of left and right lower frames 23 extending rearward from the lower part of the down frame 22, and a pair of left and right rear frames 24 extending upward from each lower frame 23. The head pipe 21 integrally and rotatably supports a front fork 14 that rotatably supports a front wheel 13F and a steering handle 15. The down frame 22 is joined to the head pipe 21 by welding or the like and extends rearward and downward from the head pipe 21. The down frame 22 may be a single frame extending rearward and downward from the head pipe 21 at the vehicle width center, or may be a pair of left and right frames extending rearward and downward from the head pipe 21.

[0011] A pair of left and right lower frames 23 are joined to the down frame 22 by welding or the like, and extend horizontally rearward with a space therebetween left and right. A fuel tank 25 for storing fuel is provided between the pair of left and right lower frames 23. The fuel tank 25 is a vehicle component that functions as an energy source for the power unit 12. In the case where the power unit 12 has a drive motor, instead of the fuel tank 25, for example, a battery that is an energy source for the drive motor, or a control device or the like is arranged. Note that the lower frame 23 may be a plate shape extending rearward from the lower part of the down frame 22, or may be a shape in which the left and right lower frames 23 are connected in the width direction.

[0012] Above the pair of left and right lower frames 23, a step floor 26 on which an occupant sitting on the vehicle seat 101 places their feet is arranged. A pair of left and right rear frames 24 integrally include a curved portion 31 that curves rearward and upward from each lower frame 23, and an upward extending portion 32 that extends rearward and upward from the curved portion 31. A cross member 27 (FIG. 2) is bridged between the left and right curved portions 31.

[0013] The down frame 22, the lower frame 23, and the rear frame 24 are composed of press frames. The press frame is manufactured by subjecting a steel plate to press working to produce a plurality of press frame members, and joining these press frame members by welding or the like. By adopting a press frame for the vehicle body frame 11, it becomes easier to obtain a large cross-sectional area compared to the case of using a round pipe. Also, compared to the case of using a round pipe, the degree of freedom in shape and the ease of processing are improved, and it becomes easier to provide concave portions 33L and 33R (see FIG. 2) that are recessed inward in the vehicle width direction.

[0014] The lower frame 23 and the rear frame 24 are integrally manufactured. That is, the lower frame 23, the curved portion 31, and the upward extending portion 32 are integrally manufactured by joining a plurality of press frame members to each other. Since the left and right curved portions 31 are continuous with the rear of the lower frame 23, it can also be referred to as the rear end portion of the lower frame 23.

[0015] Figure 2 is a sectional view taken along line II-II of Figure 1, and corresponds to a view of a pair of left and right curved portions 31 together with the peripheral configuration as seen from the front of the vehicle. In each figure including Figure 2 and the following description, among the pair of left and right curved portions 31, the left curved portion 31 is denoted as "curved portion 31L", and the right curved portion 31 is denoted as "curved portion 31R". Also, the left lower frame 23, rear frame 24 and upper extension portion 32 are respectively denoted as "lower frame 23L, rear frame 24L and upper extension portion 32L", and the right lower frame 23, rear frame 24 and upper extension portion 32 are respectively denoted as "lower frame 23R, rear frame 24R and upper extension portion 32R". Further, Figure 2 shows a plane LC (hereinafter referred to as the vehicle width center LC) that extends in the vehicle front-rear direction through the vehicle width center. As shown in Figure 2, the pair of left and right curved portions 31L, 31R each have a recess 33L, 33R that is concave inward in the vehicle width direction, and a non-recess 34L, 34R that is adjacent above the recesses 33L, 33R and protrudes outward in the vehicle width direction from the recesses 33L, 33R. The non-recesses 34L, 34R can also be referred to as the outermost side surfaces in the vehicle width direction of the curved portions 31L, 31R. Figure 2 shows the width of the vehicle body frame 11 in the pair of left and right non-recesses 34L, 34R as a value W1, and the width of the vehicle body frame 11 in the pair of left and right recesses 33L, 33R as a value W2.

[0016] In this configuration, the side stand 51 is arranged by utilizing the space SL of the recess 33L of the left curved portion 31L (corresponding to the left space formed by the difference in the widths W1 and W2 of the vehicle body frame 11), and more specifically, by utilizing the space SL that can be formed outside the recess 33L that is concave inward in the vehicle width direction. Also, the canister 61 is arranged by utilizing the space SR of the recess 33R of the right curved portion 31R (corresponding to the right space formed by the difference in the widths W1 and W2 of the vehicle body frame 11), that is, by utilizing the space SR that can be formed outside the recess 33R that is concave inward in the vehicle width direction.

[0017] As shown in FIG. 1, the side stand 51 is a vehicle component that points in the vehicle longitudinal direction in the stored position. In FIG. 2, the central axis SC of the side stand 51 in the stored position is shown with the symbol SC, and the rotation axis LT of the side stand 51 is also shown. The central axis SC of the side stand 51 is located within the space SL of the recess 33L and overlaps with the recess 33 in the vehicle width direction. Therefore, at least half of the region located at least inside the vehicle width direction from the central axis SC of the side stand 51 can be accommodated in the space SL. As a result, compared with the case where the side stand 51 is arranged outside the vehicle width direction (left side) than the non-recessed portion 34L of the left curved portion 31L, it can be arranged compactly closer to the inside in the vehicle width direction.

[0018] As shown in FIG. 2, the central axis CC of the canister 61 is located within the space SR of the recess 33R of the right curved portion 31R and overlaps with the recess 33R in the vehicle width direction. Therefore, at least half of the region of the canister 61 can be accommodated in the space SR. As a result, compared with the case where the canister 61 is arranged outside the vehicle width direction (right side) than the non-recessed portion 34R of the right curved portion 31R, it can be arranged compactly closer to the inside in the vehicle width direction.

[0019] In this way, since the side stand 51 and the canister 61 can be arranged separately on the left and right and arranged compactly closer to the inside in the vehicle width direction, it is easy to balance the left and right weights of the saddle-type vehicle 10, and an increase in the vehicle width can be suppressed. In particular, in this configuration, since the side stand 51 and the canister 61 are arranged at symmetric positions with respect to the vehicle width center LC, it becomes easier to balance the left and right weights.

[0020] Further, as shown in FIG. 2, the pair of left and right curved portions 31L and 31R are formed in a left-right symmetric shape with respect to the vehicle width center LC, including the recesses 33L and 33R and the non-recessed portions 34L and 34R. Therefore, it is easy to balance the left and right weights of the vehicle body frame 11 including the pair of left and right curved portions 31L and 31R, and it also becomes easy to balance the left and right rigidities.

[0021] The left and right recesses 33L and 33R, the side stand 51, and the canister 61 will be further described. FIG. 3 is a side view showing the left curved portion 31L together with the side stand 51. FIG. 4 is a perspective view showing the left curved portion 31L together with the side stand 51 from the lower left. As shown in FIGS. 3 and 4, in the left curved portion 31L, the non-recessed portion 34L not only forms the outermost surface in the vehicle width direction of the curved portion 31L continuously on the outer surfaces in the vehicle width direction of the left lower frame 23L and the upper extending portion 32L, but also constitutes the widest portion in the vehicle width direction of the curved portion 31.

[0022] The recess 33L extends to the rear end of the curved portion 31L below the non-recessed portion 34L and also extends to the lower end of the curved portion 31L. Specifically, the upper edge 33u constituting the upper end of the recess 33L extends rearward from the lower frame 23L side and extends to the rear end of the curved portion 31. Also, the front edge 33f constituting the front end of the recess 33 extends downward from the front end of the upper edge 33u and extends to the lower end of the curved portion 31. Thereby, the recess 33 forms a concave shape that is open to both the rear and the lower part of the vehicle.

[0023] The side stand 51 is attached to the left recess 33L via a bracket 52. Here, in each figure including FIGS. 3 and 4, the side stand 51 in the storage position is shown by a solid line, and the side stand 51 in the upright position is shown by a two-dot chain line. The bracket 52 is a vehicle component that is attached to the recess 33L by welding or the like and functions as a stand support portion for supporting the side stand 51. Specifically, the bracket 52 is formed of a plate-like member that integrates a base portion 52a attached to the recess 33L by welding or the like and a bent portion 52b that bends inward in the vehicle width direction from the lower end of the base portion 52a. The side stand 51 is movably supported at the base portion 52a of the bracket 52 in the upright position and the storage position, and is supported at a position overlapping the recess 33L in the vehicle width direction.

[0024] The side stand 51 includes a rod-shaped stand body 53 whose base end portion 53a is rotatably supported, a grounding portion 54 that projects outward in the vehicle width direction from the tip of the stand body 53, and a stand operation portion 55 that projects outward in the vehicle width direction from the middle of the stand body 53. As shown in FIG. 2, a fastening member 56A (for example, a bolt) is passed through the base end portion 53a of the stand body 53 from the outside in the vehicle width direction. By fastening this fastening member 56A to a fastened portion 57 (for example, a nut) provided on the inner side in the vehicle width direction of the base end portion 53a, the stand body 53 is rotatably fixed to the bending portion 31. A fastening member 56 is fastened to the fastening member 56A from the outside in the vehicle width direction, and by this fastening member 56, a side stand switch 58 is supported around the base end portion 53a of the stand body 53. The side stand switch 58 is a switch for detecting whether the side stand 51 is in the upright position or the stored position. As shown in FIG. 2, the central axes of the fastening members 56, 56A and the fastened portion 57 coincide with the rotation axis LT of the side stand 51.

[0025] The grounding portion 54 is a portion that contacts the ground in the upright position, and the stand operation portion 55 is a portion that is operated by the user's (for example, the rider's) foot when rotating the stand body 53. As shown in FIG. 4, the base portion 52a of the bracket 52 extends between the stand body 53 and the recess 33L, and the bent portion 52b of the bracket 52 passes below the recess 33L and extends inward in the vehicle width direction from the recess 33L. The bent portion 52b constitutes the lower end portion of the bracket 52, and a notch portion 52k is formed by notching a part of this lower end portion. The notch portion 52k is provided at a position corresponding to the inner side in the vehicle width direction of the fastened portion 57.

[0026] FIG. 5 is a rear view of the vehicle showing the fastened portion 57 together with the surrounding configuration. The notch portion 52k is formed in a notch shape that allows a part of a predetermined tool 70 shown in FIG. 5 to pass through. By passing the tool 70 through the notch portion 52k, as shown in FIG. 5, the tool 70 can access the fastened portion 57 of the side stand 51. Specifically, when fastening the fastened portion 57 shown in FIG. 3 to attach the side stand 51, the tool 70 can restrict the rotation of the fastened portion 57 or rotate the fastened portion 57. This enables the attachment operation of the side stand 51 to be easily performed. Also, when removing the fastened portion 57 to remove the side stand 51, the tool 70 can restrict the rotation of the fastened portion 57 or rotate the fastened portion 57, and the removal operation can also be easily performed.

[0027] The rotation axis LT of the side stand 51 is the rotation axis of the stand body 53. Since the rotation axis of the stand body 53 is inward in the vehicle width direction and downward in the rear view of the vehicle shown in FIG. 5, when the side stand 51 is changed from the storage position shown in FIG. 5 to the upright position, the tip of the stand body 53 moves outward in the vehicle width direction, and the grounding portion 54 provided at the tip of the stand body 53 can be positioned sufficiently away from the outside in the vehicle width direction.

[0028] The region AR1 in FIG. 5 indicates the region of the base end portion 53a of the stand body 53. In this configuration, when the side stand 51 is changed from the upright position to the storage position, in the rear view of the vehicle shown in FIG. 5, at least the entire stand body 53 of the side stand 51 overlaps with the region AR1 of the base end portion 53a of the stand body 53 in the front-rear direction. Thereby, while the grounding portion 54 of the side stand 51 is positioned sufficiently away from the outside in the vehicle width direction in the upright position, the side stand 51 can be arranged compactly in the vehicle width direction in the storage position.

[0029] As shown in FIG. 3, in this configuration, since the concave portion 33L extends continuously to the rear end of the curved portion 31L, even when the side stand 51 in the storage position extends long in the front-rear direction, the side stand 51 does not contact the rear frame 24L. Moreover, since the concave portion 33L extends continuously to the lower end of the curved portion 31L, even when the side stand 51 is in the upright position, the side stand 51 does not contact the lower frame 23L. Therefore, even when the side stand 51 is long in the vehicle front-rear direction and the vehicle vertical direction, the side stand 51 can be arranged compactly in the vehicle width direction and can be arranged so as not to contact the vehicle body frame 11.

[0030] FIG. 6 is a side view showing the right curved portion 31R together with the canister 61. FIG. 7 is a view showing the right curved portion 31R together with the canister 61 from above. The canister 61 is a vehicle component that functions as an evaporative fuel emission control device and is formed in a cylindrical shape with both ends closed. As shown in FIGS. 6 and 7, the canister 61 is supported by an annular support member 62. This support member 62 is a rubber vibration-proof member. A stay 62s, which is an iron member, is welded to the right curved portion 33R that is a part of the vehicle body frame 11, and the support member 62 is inserted through this stay 62s, whereby the support member 62 is supported by the curved portion 31R. Thereby, the canister 61 is rubber-mounted to the vehicle body frame 11.

[0031] The canister 61 is arranged with its central axis CC along the vehicle front-rear direction, and in the side view of the vehicle shown in FIG. 6, it is at a position overlapping the right concave portion 33R, and in the top view of the vehicle shown in FIG. 7, it is at a position overlapping the non-concave portion 34 in the vertical direction. Thereby, the canister 61 can be arranged using the space within the concave portion 33R. In this configuration, since the central axis CC of the canister 61 overlaps the right concave portion 33R in the side view of the vehicle shown in FIG. 6 and overlaps the non-concave portion 34R in the vertical direction in the plan view shown in FIG. 7, more than half of the area of the canister 61 can be arranged in the space of the concave portion 33R. Thereby, the canister 61 can be arranged compactly in the vehicle width direction.

[0032] Regarding the recess 33R in which the canister 61 is disposed, as shown in FIG. 6, since it continuously extends to the rear end of the curved portion 31R, even when the canister 61 extends longitudinally, the canister 61 can be prevented from contacting the rear frame 24R. Moreover, since the recess 33R continuously extends to the lower end of the curved portion 31R, even when the canister 61 is large in the vertical direction, the canister 61 can be arranged so as not to contact the rear frame 24R. Thus, even when the canister 61 is enlarged in either the vehicle longitudinal direction or the vehicle vertical direction, the canister 61 can be arranged so as not to contact the vehicle body frame 11 while being arranged compactly in the vehicle width direction.

[0033] As shown in FIGS. 6 and 7, a charge pipe 63 connected to the fuel tank 25 is connected to the front portion of the canister 61. Through this charge pipe 63, the evaporated fuel generated in the fuel tank 25 flows into the canister 61 and is adsorbed by the adsorption member in the canister 61. In this configuration, a metal pipe member 65 through which the charge pipe 63 passes is provided on the right lower frame 23R corresponding to the canister 61 side. This pipe member 65 penetrates the lower frame 23R and is joined to the lower frame 23R by welding or the like. By this pipe member 65, the space of the lower frame 23R can be used as the routing space for the charge pipe 63, and the routing of the charge pipe 63 becomes easier.

[0034] The pipe member 65 of this configuration extends obliquely linearly upward in front in the side view of the vehicle shown in FIG. 6, and extends obliquely linearly forward and inward in the vehicle width direction in the top view of the vehicle shown in FIG. 7. By providing the pipe member 65 in this way, as shown in FIG. 7, the charge pipe 63 can be routed so as to connect the canister 61 and the connection portion of the charge pipe 63 in the fuel tank 25 (around the fuel filler 25a in this configuration) by a short path (for example, a path close to a straight line). Therefore, it is also possible to shorten the pipe length compared to the case where the charge pipe 63 is routed to bypass the lower frame 23R.

[0035] In addition, in FIGS. 6 and 7, only the charge pipe 63 is illustrated among the plurality of pipes connected to the canister 61, and the other pipes other than the charge pipe 63 may be arranged as appropriate. The other pipes include a purge pipe that guides the evaporated fuel in the canister 61 to the intake side of the power unit 12 (the intake side of the internal combustion engine), an air introduction pipe that introduces external air into the canister 61, and a drain pipe that discharges moisture and the like in the canister 61. Regarding the other pipes, they may be arranged around the vehicle body frame 11 so as to bypass the vehicle body frame 11 including the curved portions 31, or any of the other pipes may be arranged so as to pass through the pipe member 65.

[0036] As described above, the saddle-type vehicle 10 of the present embodiment includes a pair of left and right curved portions 31L and 31R that extend upward from the pair of left and right lower frames 23L and 23R. Each of the curved portions 31L and 31R has recesses 33L and 33R that are recessed inward in the vehicle width direction. Each of the recesses 33L and 33R extends continuously to the rear ends of the respective curved portions 31L and 31R, and at least a part of the vehicle components including the side stand 51 and the canister 61 is arranged in each of the recesses 33L and 33R. Since each of the recesses 33L and 33R extends continuously to the rear ends of the respective curved portions 31L and 31R, and at least a part of the vehicle components 51 and 61 is arranged in each of the recesses 33L and 33R, even if the vehicle components 51 and 61 are components that are long in the vehicle front-rear direction, the vehicle components 51 and 61 can be arranged compactly in the vehicle width direction by using the space in the recesses 33L and 33R.

[0037] Also, as shown in FIGS. 2 and 5 and the like, each of the recesses 33L and 33R extends continuously to the rear ends of the respective curved portions 31L and 31R and also extends continuously to the lower ends of the respective curved portions 31L and 31R. Therefore, when viewed from the rear of the vehicle, in each of the curved portions 31L and 31R, the region corresponding to each of the recesses 33L and 33R is notched inward in the vehicle width direction and opens downward of the vehicle. In a rear view of the vehicle, in each of the curved portions 31L and 31R, the region corresponding to each of the recessed portions 33L and 33R is notched inward in the vehicle width direction and opens downward of the vehicle. Therefore, even when the vehicle components 51 and 61 are long in the vehicle longitudinal direction and the vehicle vertical direction, the vehicle components 51 and 61 can be arranged compactly in the vehicle width direction and can be arranged so as not to contact the vehicle body frame 11.

[0038] Further, the vehicle components 51 and 61 include a side stand 51 that is movable between a standing position and a storage position. The recessed portion 33L on the left side overlaps at least a part of the side stand 51 in the vehicle width direction, and the upper end of the recessed portion 33L is located above the side stand 51. Since the recessed portion 33L on the left side overlaps at least a part of the side stand 51 in the vehicle width direction and the upper edge 33u corresponding to the upper end of the recessed portion 33L is located above the side stand 51, the side stand 51 having a length in the front-rear direction or the like can be arranged compactly in the vehicle width direction by using the space in the recessed portion 33L on the left side.

[0039] Also, at least a part of the side stand 51 is arranged in the recessed portion 33L on the left side, and at least a part of the canister 61 is arranged in the recessed portion 33R on the right side. Therefore, both the side stand 51 and the canister 61, which tend to be long in the vehicle longitudinal direction or the like, can be arranged compactly in the vehicle width direction by using the left and right recessed portions 33L and 33R, and it becomes easier to balance the left and right weights of the saddle-type vehicle 10. Note that the side stand 51 corresponds to the "stand" of the present invention.

[0040] Also, a bracket 52 that functions as a stand support portion for supporting the side stand 51 is arranged between the recessed portion 33L on the left side and the side stand 51, and a notch portion 52k is provided in the bracket 52. By inserting a predetermined tool 70 through the notch portion 52k, it becomes possible to access the fastened portion 57, which is a predetermined portion of the side stand 51, with the tool 70. Therefore, when accessing a predetermined location with the predetermined tool 70, the bracket 52 does not get in the way, and the work using the tool 70 can be easily performed.

[0041] Note that the predetermined location of this embodiment and the tool 70 are merely examples. If the structure of the side stand 51 or the like is different, the predetermined location and the tool are appropriately changed. That is, the "predetermined location" of the present invention may be any location where various operations of the saddle-riding type vehicle 10 are performed, and the notch 52k only needs to be able to insert a tool used for the operation toward the predetermined location. With this notch 52k, the stand support portion does not get in the way when accessing a predetermined tool at a predetermined location, and it becomes possible to easily perform a predetermined operation using the predetermined tool.

[0042] Also, among the pair of left and right lower frames 23L and 23R, a pipe member 65 through which a charge pipe 63 connected to the canister 61 passes penetrates the lower frame 23R on the canister 61 side. According to this configuration, a routing space for the charge pipe 63 connected to the canister 61 can be secured inside the lower frame 23R, and the routing of the charge pipe 63 becomes easier. Note that, in this embodiment, the case where the pipe member 65 through which the charge pipe 63 passes penetrates the lower frame 23R is illustrated, but it is not limited to this. A pipe member through which another pipe (for example, a purge pipe, an air introduction pipe, a drain pipe) other than the charge pipe passes may penetrate the lower frame 23R.

[0043] Note that the above-described embodiment shows one aspect of the present invention. The present invention is not limited to the above-described embodiment, and the configuration such as details may be appropriately changed. For example, the shape, structure, and material of the vehicle body frame 11 may be changed. As a specific example, the number of the lower frames 23 and the curved portions 31 may be changed, and the lower frames 23 and the curved portions 31 may be singular.
