[0009] A saddle-type vehicle according to one embodiment of the present invention runs on power from a main battery and a sub-battery. A storage box is installed under the seat, a main holder is installed outside the storage box, and a sub-holder is installed inside the storage box. The main battery is held in the main holder, and the sub-battery is held in the sub-holder. Since the main battery is not installed inside the storage box, storage space for items is secured in addition to the storage space for the sub-battery. It is possible to secure storage space inside the storage box while ensuring a mileage with the main battery and the sub-battery. In addition, the storage space of the storage box can be widely used by removing the sub-battery. EXAMPLES

[0010] The saddle riding type vehicle of this embodiment will be described below with reference to the accompanying drawings. Fig. 1 is a left side view of the saddle riding type vehicle of this embodiment. Fig. 2 is a right side view of the saddle riding type vehicle of this embodiment. Note that the following figures show a state in which a body cover is removed from the saddle riding type vehicle. Also, in the following figures, the arrow Fr indicates the front of the vehicle, the arrow Re indicates the rear of the vehicle, the arrow L indicates the left side of the vehicle, and the arrow R indicates the right side of the vehicle.

[0011] 1 and 2, a low floorboard 45 is installed on the body frame 10 of the saddle-type vehicle 1 in front of the seat 41. A head pipe 11 is provided at the front end of the body frame 10, and a front frame 12 extends diagonally rearward and downward from the head pipe 11. A pair of left and right lower frames 13 are connected to the lower part of the front frame 12, and the pair of lower frames 13 extend rearward below the floorboard 45. A pair of side frames 14 rise from rear portions of the pair of lower frames 13 toward the seat 41, and upper portions of the pair of side frames 14 are bent rearward to form a seat frame 15.

[0012] A front fork 31 is steerably supported on the head pipe 11 via a steering shaft (not shown). A handle 32 is provided on the upper part of the steering shaft, and a front wheel 33 is rotatably supported on the lower part of the front fork 31. A pair of U-shaped rear frames 16 extend rearward from the pair of side frames 14, and a rear wheel 34 is rotatably supported on a pair of rear brackets 18 at the rear ends of the pair of rear frames 16. A rear fender 35 is attached to the upper parts of the rear brackets 18 and the rear frames 16, and the rear wheel 34 is covered from above by the rear fender 35.

[0013] A seat 41 is supported on the pair of seat frames 15, and a storage box 29 is installed below the seat frames 15. The storage box 29 is located inside the pair of side frames 14, and an upper access opening of the storage box 29 is covered from above by the seat 41. A floor board 45 is installed on the pair of lower frames 13, and the legs of a driver seated in the seat 41 are placed on the tread surface of the floor board 45. A battery 53 is installed via a battery holder 50 on the upper rear surface of the floor board 45 or in the storage box 29, and a motor 60 is installed on the lower rear side of the floor board 45.

[0014] Although details will be described later, in the saddle riding type vehicle 1 of this embodiment, a main holder 51 and a sub-holder 52 are provided as the battery holder 50. A main battery 54 that supplies power to the motor 60 is detachably held in the main holder 51, and a sub-battery 55 that supplies backup power to the motor 60 is detachably held in the sub-holder 52. In the following, when there is no need to distinguish between the main holder 51 and the sub-holder 52, they will be collectively referred to as the battery holder 50, and when there is no need to distinguish between the main battery 54 and the sub-battery 55, they will be collectively referred to as the battery 53.

[0015] A drive sprocket 36 is provided on the output shaft of the motor 60, and a driven sprocket 37 is provided on the axle of the rear wheel 34. The drive sprocket 36 of the motor 60 and the driven sprocket 37 of the rear wheel 34 are connected via a chain 38. Electricity is supplied to the motor 60 from a battery 53, and the motor 60 drives the rear wheel 34 via the drive sprocket 36, the chain 38, and the driven sprocket 37. A side stand 39 is provided on the left lower frame 13, and by raising the side stand 39, the vehicle body can stand on its own while tilted to the left (one side in the vehicle width direction).

[0016] In an electric saddle-type vehicle 1 equipped with a main battery 54 and a sub-battery 55, the tread surface of the floorboard 45 and the storage box 29 may not be sufficiently secured depending on the battery layout. Also, in a typical saddle-type vehicle, two batteries are installed in the storage box, but the interior of the storage box is occupied by the two batteries and items such as a helmet cannot be stored. Therefore, in the saddle-type vehicle 1 of this embodiment, the main battery 54 is installed outside the storage box 29 and the sub-battery 55 is installed inside the storage box 29, and sufficient storage space for items is secured inside the storage box 29.

[0017] The rear structure of the saddle riding type vehicle will be described below with reference to Fig. 3 and Fig. 4. Fig. 3 is a right side view of the rear part of the vehicle body of this embodiment. Fig. 4 is a cross-sectional view of the saddle riding type vehicle of Fig. 2 taken along line AA.

[0018] 3, a seat 41 is supported on the pair of seat frames 15, and the seat 41 protrudes forward beyond the front surface of the storage box 29. In a side view, the front surface of the storage box 29 is formed parallel to the pair of side frames 14, and the storage box 29 is installed inside the body cover 26 that covers the pair of side frames 14. Inside the body cover 26, a lower portion of the storage box 29 is supported by a frame bridge 21 that connects the lower portions of the pair of side frames 14, and an upper portion of the storage box 29 is supported by a frame bridge 22 that connects the rear sides of the pair of seat frames 15.

[0019] A pair of side frames 14 rise from the rear of the floorboard 45 toward the seat 41, and the seat 41 protrudes forward beyond the pair of side frames 14. The front half of the seat 41 faces the floorboard 45, and the rear half of the floorboard 45 is covered from above by the front half of the seat 41. The pair of side frames 14 and the storage box 29 are located inside the body cover 26, and the outside of the body cover 26 is an external space sandwiched between the floorboard 45 and the seat 41 from above and below. The external space between the floorboard 45 and the seat 41 is open to the surroundings except for the rear.

[0020] A main holder 51 is installed in the external space between the floor board 45 and the seat 41, and a sub-holder 52 (see FIG. 4) is installed inside the storage box 29. A main battery 54 is held in the main holder 51, and a sub-battery 55 (see FIG. 5) is held in the sub-holder 52. The pair of side frames 14 are positioned rearward of the main battery 54 so that the main battery 54 does not overlap with the side frames 14 in a side view. By exposing the main battery 54 to the outside from the body cover 26, the ease of attachment and detachment of the main battery 54, which is frequently attached and detached, is improved.

[0021] The main holder 51 is located between the front end of the seat 41 and the side frame 14. When the main battery 54 is held in the main holder 51, the main battery 54 is also positioned rearward of the front end of the seat 41. In this manner, the main battery 54 is installed using the space rearward of the driver's legs. When the driver has lowered his / her legs straight down, the main battery 54 does not interfere with the driver's legs, and the floor board 45 in front of the seat 41 has a sufficient tread surface for the driver's legs to rest on. In addition, the main holder 51 is installed in the center in the vehicle width direction, and the sides of the main battery 54 can also be used as tread surfaces for the driver's legs.

[0022] The main battery 54 is held by the main holder 51 so as to fit along the side frame 14, and the inclination of the rear surface of the main battery 54 is approximately parallel to the inclination of the side frame 14. The main battery 54 is also inclined forward so that its upper end is further forward than its lower end. The main battery 54 is brought closer to the side frame 14, and the lower end of the main battery 54 is positioned rearward, thereby ensuring a wide tread surface of the floorboard 45. The motor 60 is installed directly below the main battery 54, and the main battery 54 and the motor 60 are arranged vertically in a side view, thereby allowing the main battery 54 and the motor 60 to be installed compactly.

[0023] The floorboard 45 is supported from below by a pair of lower frames 13, and the motor 60 is positioned below the lower frames 13. In addition, a base end portion 17 of the rear frame 16 is located near the boundary between the lower frame 13 and the side frames 14, and the motor 60 is positioned below the base end portion 17 of the rear frame 16. Since the motor 60, which is a heavy object, is located in a low position, the center of gravity of the vehicle body is lowered, improving driving stability. Furthermore, since the drive shaft center O1 of the motor 60 is located below the rotation shaft center O2 of the rear wheels 34 when the vehicle is stopped, the center of gravity of the vehicle body is further lowered, improving driving stability.

[0024] As shown in Fig. 4, a main holder 51 (see Fig. 5) is installed outside the storage box 29. The main holder 51 is formed in a concave shape that is open on the upper side and the left side, and the main battery 54 can be attached to and detached from the left side of the main holder 51. A pair of guide holes (not shown) are formed in the front and rear walls of the main holder 51, and a pair of guide shafts (not shown) that fit into the guide holes are formed in the lower part of the main battery 54. In addition, a holder terminal (not shown) protrudes from the bottom surface of the main holder 51, and a battery terminal (not shown) is provided inside an insertion port on the bottom surface of the main battery 54.

[0025] A sub-holder 52 is installed in the storage box 29. The sub-holder 52 is formed in a concave shape with an open upper side, and the sub-battery 55 can be attached to and detached from the upper side of the sub-holder 52. A pair of guide holes (not shown) are formed in the left and right walls of the sub-holder 52, and a pair of guide shafts (not shown) that fit into the guide holes are formed in the lower part of the sub-battery 55. In addition, a holder terminal (not shown) protrudes from the bottom surface of the sub-holder 52, and a battery terminal (not shown) is provided in an insertion port on the bottom surface of the sub-battery 55. In this way, the main battery 54 and the sub-battery 55 are installed separately inside and outside the storage box 29.

[0026] In this case, the main battery 54 can be attached to and detached from the main holder 51 from the side stand 39 side. The side stand 39 is provided on the left side of the vehicle body, and when the saddle-type vehicle 1 is stopped, the vehicle body is tilted to the left and stands on its own. Because the main holder 51 is tilted to the left, the main battery 54 can be smoothly attached to and detached from the main holder 51 from the left side. In addition, the sub-battery 55 can be attached to and detached from the sub-holder 52 from above. Because the sub-holder 52 is tilted forward, the sub-battery 55 can be smoothly attached to and detached from the sub-battery 55 from above, using the front surface of the storage box 29 as a guide surface.

[0027] A locking mechanism 56 is provided on the right side of the main battery 54 outside the storage box 29. The locking mechanism 56 is attached to a cross plate (not shown) that connects the pair of side frames 14. A locking piece (not shown) is provided on the locking mechanism 56, and a locking hole (not shown) is provided on the main battery 54. A key cylinder (not shown) is provided on the front side of the locking mechanism 56, and when the key cylinder is rotated with a mechanical key, the locking piece fits into the locking hole, locking the main battery 54 so that it cannot be attached or detached. When the seat 41 is locked in the closed state, the attachment and detachment of the sub-battery 55 is restricted.

[0028] The battery layout will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a cross-sectional view of the rear part of the vehicle body in Fig. 4 taken along line BB. Fig. 6 is a cross-sectional view of the rear part of the vehicle body in Fig. 5 taken along line CC.

[0029] As shown in Fig. 5, a storage box 29 is installed below the seat 41. The lower front part of the storage box 29 is supported by a frame bridge 21 connecting a pair of side frames 14, and the upper rear part of the storage box 29 is supported by a frame bridge 22 connecting a pair of seat frames 15 (see Fig. 4). The rear side of the lower part of the storage box 29 is curved so as to avoid the rear fender 35. A main holder 51 is installed outside the storage box 29, and a sub-holder 52 is installed inside the storage box 29, with a main battery 54 on the main holder 51 and a sub-battery 55 on the sub-holder 52 lined up in the front-rear direction below the seat 41.

[0030] A seat 41 is connected to the front ends of the pair of seat frames 15 via a hinge mechanism 42. The seat 41 opens and closes an access opening on the top surface of the storage box 29, and the sub-battery 55 is attached to and detached from the sub-holder 52 through the access opening of the storage box 29. The front surface of the sub-battery 55 faces the front surface of the storage box 29, and the sub-battery 55 is installed so as to be parallel to the front surface of the storage box 29 in a side view. The sub-battery 55 is also tilted forward so that the upper end portion is forward of the lower end portion. This ensures a storage space for a helmet 76 above and behind the sub-battery 55.

[0031] The sub-battery 55 is located behind the frame bridge 21 inside the storage box 29. The lower front portion of the storage box 29 near the sub-battery 55 is supported by the frame bridge 21, so that the sub-battery 55 is held in a position close to the side frame 14 and vibration is suppressed. In a side view, the side frame 14 overlaps the front end portion of the storage box 29 and extends along the front surface of the storage box 29. As a result, the side of the storage box 29 rearward of the side frame 14 is expanded in the vehicle width direction, ensuring a large storage space for the helmet 76 (see FIG. 6).

[0032] As shown in Figures 5 and 6, the sub-battery 55 is installed in the center of the storage box 29 in the vehicle width direction, and an empty space is provided between the sub-battery 55 and the seat 41. The dimension of the sub-battery 55 in the vehicle width direction is smaller than the dimensions of the sub-battery 55 in the front-rear direction and in the height direction. An empty space is provided not only above the sub-battery 55 but also on both sides of the sub-battery 55. The empty space in the storage box 29 is formed so that a helmet 76 can be stored. An interior material is provided on the approximately hemispherical outer shell of the helmet 76, and an attachment opening 77 into which the head fits is formed on the underside of the helmet 76.

[0033] When the helmet 76 is stored in the storage box 29 with the mounting opening 77 facing downward, the sub-battery 55 inside the storage box 29 enters from the mounting opening 77 of the helmet 76 and is positioned inside the helmet 76. The sub-battery 55 is held by the sub-holder 52 so that the sub-battery 55 fits into the mounting opening 77 of the helmet 76. By the sub-battery 55 fitting into the hollow portion of the helmet 76, the sub-battery 55 and the helmet 76 are stored compactly inside the storage box 29. Because the storage box 29 is not unnecessarily large, the volume of the rear of the vehicle can be reduced.

[0034] As described above, according to the saddle riding type vehicle 1 of this embodiment, since the main battery 54 is not installed inside the storage box 29, storage space for items is secured in addition to storage space for the sub-battery 55. It is possible to ensure a travel distance by the main battery 54 and the sub-battery 55, while also securing storage space inside the storage box 29. In addition, by removing the sub-battery 55, the storage space of the storage box 29 can be widely used.

[0035] In this embodiment, the main holder is installed above the floor board, but the installation location of the main holder is not particularly limited as long as the main holder is installed outside the storage box and the sub-holder is installed inside the storage box. For example, the main holder may be installed behind the storage box.

[0036] Further, in this embodiment, the main holder is disposed in the center in the vehicle width direction, but the main holder may be disposed offset to one side or the other side in the vehicle width direction.

[0037] In this embodiment, a half helmet is stored in the storage box as a helmet, but the type of helmet stored in the storage box is not particularly limited. For example, a full-face helmet or an open-face helmet may be stored in the storage box as a helmet.

[0038] The battery layout of this embodiment is not limited to the above-mentioned saddle-ride type vehicle, and may be adopted in other saddle-ride type vehicles. Note that the saddle-ride type vehicle is not limited to all vehicles in which the rider sits astride the seat, but also includes scooter-type vehicles in which the rider does not sit astride the seat.

[0039] As described above, the first aspect is a saddle-type vehicle (1) that can run on the power of a main battery (54) and a sub-battery (55), and includes a storage box (29) installed under a seat (41), a main holder (51) that holds the main battery, and a sub-holder (52) that holds the sub-battery, with the main holder installed outside the storage box and the sub-holder installed inside the storage box. With this configuration, the main battery is not installed inside the storage box, so that storage space for items is secured in addition to the storage space for the sub-battery. While ensuring a mileage with the main battery and the sub-battery, storage space in the storage box can also be secured. Also, by removing the sub-battery, the storage space of the storage box can be widely used.

[0040] In the second aspect, the storage box in the first aspect can store a helmet (76), and the sub-battery is held in the sub-holder so that the sub-battery fits into the helmet mounting opening (77). With this configuration, the sub-battery fits into the hollow part of the helmet, so that the sub-battery and the helmet are stored compactly in the storage box. Since the storage box is not unnecessarily large, the volume of the rear part of the vehicle can be reduced.

[0041] In the third aspect, in the first or second aspect, the main holder is disposed at the center in the vehicle width direction. With this configuration, the sides of the main battery can be used as tread surfaces for the driver's legs.

[0042] Although the present embodiment has been described, other embodiments may be made by combining the above-described embodiments and modifications in whole or in part.

[0043] In addition, the technology of the present invention is not limited to the above examples, and may be modified, substituted, or altered in various ways without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to the progress of technology or a different technology derived therefrom, the invention may be implemented using that method. Therefore, the claims cover all embodiments that may be included within the scope of the technical idea. [Explanation of symbols]
