Description

[Technical field]

[0001] The present invention relates to a saddle-type vehicle. [Background technology]

[0002] In recent years, electric straddle-type vehicles that run on electricity have been developed. A known example of this type of straddle-type vehicle is a scooter-type vehicle in which a battery is installed below a low-floor board (see, for example, Patent Document 1). In the straddle-type vehicle described in Patent Document 1, a pair of lower frames pass below the floor board, and a pair of side frames rise backward from the rear ends of the pair of lower frames toward the seat. A storage box is installed between the pair of side frames below the seat, and a battery is installed between the pair of lower frames below the floor board. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-63064 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the saddle-type vehicle described in Patent Document 1, the battery cannot be easily attached or detached below the floor board. It is possible to store the battery in a storage box below the seat, but this would prevent the storage space from being used effectively and would also make it difficult to attach or detach the battery.

[0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a saddle-type vehicle in which the ease of attaching and detaching the battery is improved and sufficient space can be secured below the seat. [Means for solving the problem]

[0006] One embodiment of the present invention is a saddle-type vehicle that can run on battery power, and is equipped with a low-floor board on which the driver's legs are placed, a seat that covers the rear of the floor board from above, and a battery holder that removably holds the battery, with the space between the seat and the floor board exposed to the outside, the battery holder installed in the space, and the battery holder positioned above the floor board, thereby solving the above-mentioned problems. Effect of the Invention

[0007] According to the saddle-type vehicle of one aspect of the present invention, since the battery holder is exposed to the outside on the floor board, the battery can be easily attached to and detached from the battery holder without opening and closing the seat. In addition, the battery is not stored in the storage box under the seat, so the storage box can be used effectively. Since the floor board is located under the seat, the area around the battery can also be used as the tread surface of the floor board. [Brief description of the drawings]

[0009] A saddle-type vehicle according to one aspect of the present invention runs on power from a battery removably held in a battery holder. The driver's legs are placed on the low-floor board of the saddle-type vehicle, and the rear part of the floor board is covered from above by a seat. The space between the floor board and the seat is exposed to the outside, and a battery holder is installed in this space and positioned above the floor board. Since the battery holder is exposed to the outside on the floor board, the battery can be easily attached to and detached from the battery holder without opening or closing the seat. In addition, the battery is not stored in a storage box below the seat, and the storage box can be effectively used. Since the floor board is also located below the seat, the area around the battery can also be used as a tread surface for the floor board. 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, and a motor 60 is installed on the lower rear side of the floor board 45.

[0014] 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).

[0015] In an electric saddle-type vehicle 1, depending on the battery layout, the storage space below the seat 41 may become narrow and the attachment and detachment of the battery 53 may become difficult. For example, if the battery is installed below the seat, it may be difficult to secure a sufficient storage space below the seat. Also, while it is conceivable to install the battery below the floorboard, it is difficult to attach and detach the battery below the floorboard. Therefore, in the saddle-type vehicle 1 of this embodiment, the external space between the seat 41 and the floorboard 45 is utilized, and the battery holder 50 is installed in the external space, and the battery holder 50 is positioned above the floorboard 45.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] A battery holder 50 is installed in the external space between the floor board 45 and the seat 41, and a battery 53 is detachably held in the battery holder 50. The pair of side frames 14 are positioned rearward of the battery 53 so that the battery 53 does not overlap the side frames 14 in a side view. The battery 53 is exposed to the outside from the body cover 26, improving the ease of attachment and detachment of the battery 53. In addition, the storage space of the storage box 29 is not narrowed by the battery 53.

[0020] The battery holder 50 is located between the front end of the seat 41 and the side frame 14. When the battery 53 is held in the battery holder 50, the battery 53 is also positioned rearward of the front end of the seat 41. In this manner, the battery 53 is installed using the space rearward of the driver's legs. When the driver has lowered his / her legs straight down, the battery 53 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 battery holder 50 is installed in the center in the vehicle width direction, and the sides of the battery 53 can also be used as tread surfaces for the driver's legs.

[0021] The battery 53 is held by the battery holder 50 so as to be aligned with the side frame 14, and the inclination of the rear surface of the battery 53 is approximately parallel to the inclination of the side frame 14. The battery 53 also inclines forward so that its upper end is further forward than its lower end. The battery 53 is brought closer to the side frame 14, and the lower end of the battery 53 is positioned rearward, thereby ensuring a wide tread surface of the floor board 45. The motor 60 is installed directly below the battery 53, and the battery 53 and the motor 60 are arranged vertically in a side view, thereby allowing the battery 53 and the motor 60 to be installed compactly.

[0022] 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.

[0023] As shown in Fig. 4, a battery holder 50 is installed above the floorboard 45. The battery holder 50 is formed in a concave shape that is open on the upper and left sides, and the battery 53 can be attached and detached to the battery holder 50 from the left side. A pair of guide holes (not shown) are formed in the front and rear walls of the battery holder 50, and a pair of guide shafts (not shown) that fit into the guide holes are formed on the lower part of the battery 53. In addition, a holder terminal (not shown) protrudes from the bottom surface of the battery holder 50, and a battery terminal (not shown) is provided inside an insertion port on the bottom surface of the battery 53.

[0024] In this case, the battery 53 can be attached to and detached from the battery holder 50 from the side stand 39 side. The side stand 39 is provided on the left side of the vehicle body, and when the saddle riding type vehicle 1 is stopped, the vehicle body is tilted to the left and stands on its own. Because the battery holder 50 is tilted to the left, the battery 53 can be smoothly attached to and detached from the left side of the battery holder 50. The amount that the battery holder 50 is tilted to the left is reduced by the amount that the battery 53 needs to be raised or tilted when being attached or detached. In addition, the weight of the battery 53, which is a heavy object, is utilized to facilitate removal of the battery 53 from the battery holder 50.

[0025] A locking mechanism 56 is provided on the right side of the battery 53. The locking mechanism 56 is attached to the cross plate 25 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 in the battery 53. A key cylinder 58 is provided on the front side of the locking mechanism 56, and when the key cylinder 58 is rotated with a mechanical key, the locking piece fits into the locking hole, locking the battery 53 so that it cannot be attached or detached. Because the locking mechanism 56 is provided on the opposite side to the side of the side stand 39, the locking mechanism 56 does not interfere with the attachment and detachment of the battery 53.

[0026] The battery layout will be described with reference to Figures 5 and 6. Figure 5 is a cross-sectional view of the rear part of the vehicle body taken along line BB in Figure 4. Figure 6 is a top view of the rear part of the vehicle body of this embodiment.

[0027] 5, a motor bracket 63 is attached to the vehicle body frame 10, and a battery bracket 71 is attached onto the motor bracket 63. The motor 60 is supported from above by the motor bracket 63, and the battery 53 is supported from below via the battery holder 50 by the battery bracket 71. A base plate 64 of the motor bracket 63 is formed to have an upper surface and both side surfaces, and the base plate 64 is positioned inside the pair of lower frames 13 with both side surfaces facing in the vehicle width direction.

[0028] The front side of the base plate 64 is screwed to the pair of lower frames 13, and the rear side of the base plate 64 is screwed to the pair of rear frames 16. A front support plate 67 is joined to the front side of the lower surface of the base plate 64, and a rear support plate 68 is joined to the center of the lower surface of the base plate 64. A front mounting portion 61 on the front side of the upper part of the motor 60 is screwed to the front support plate 67, and a rear mounting portion 62 on the upper center of the motor 60 is screwed to the rear support plate 68. In this manner, the motor 60 is attached to the vehicle body frame 10 via the motor bracket 63.

[0029] The battery bracket 71 is formed by joining a lower plate 72 and an upper plate 73 with a support member 74. The lower plate 72 of the battery bracket 71 is screwed to the upper surface of the base plate 64 of the motor bracket 63. The support member 74 stands up from the rear side of the upper surface of the lower plate 72 of the battery bracket 71. A notch 46 is formed in the rear side of the floor board 45, and the support member 74 protrudes upward beyond the floor board 45 through the notch 46. The upper plate 73 is supported on the upper end of the support member 74, and the upper plate 73 is positioned on the floor board 45.

[0030] The upper plate 73 of the battery bracket 71 is formed long in the vehicle width direction. The battery holder 50 is screwed to the upper surface of the upper plate 73. In this manner, the battery holder 50 is supported by the battery bracket 71 protruding above the floor board 45 through the notch 46. Because the battery holder 50 is located above the floor board 45, it can be installed regardless of the rear shape of the floor board 45. Even if the battery 53 is exposed above the floor board 45, the floor board 45 protects the battery 53 from splashes of water, flying stones, and the like from below.

[0031] Although the rear part of the floorboard 45 is curved upward, the battery 53 is held in the battery holder 50 so that the battery 53 is higher than the rear upper surface of the floorboard 45. Above the floorboard 45, the upper plate 73 of the battery bracket 71 is tilted forward, and the battery holder 50 on the upper plate 73 is tilted to reduce interference between the battery 53 held in the battery holder 50 and the floorboard 45. The battery 53 is installed on the curved rear side of the floorboard 45, and a wide tread surface of the floorboard 45 is ensured in front of the battery 53.

[0032] 6, the front part of the floorboard 45 is cut out in a V-shape, and the rear part of the floorboard 45 is cut out in a rectangular shape (the rear cutout is not shown). The rear end 47 of the floorboard 45 is located approximately in the center of the seat 41 in the front-rear direction, and both ends 48, 49 of the floorboard 45 in the vehicle width direction are located outside the seat 41 in the vehicle width direction. The entire battery holder 50 is located forward of the rear end 47 of the floorboard 45 and inside both ends 48, 49 of the floorboard 45 in the vehicle width direction. As a result, the floorboard 45 protects the entire battery 53 from splashes of water, flying stones, and the like from below.

[0033] As described above, according to the saddle riding type vehicle 1 of this embodiment, since the battery holder 50 is exposed to the outside on the floor board 45, the battery 53 can be easily attached to and detached from the battery holder 50 without opening or closing the seat 41. Furthermore, since the battery 53 is not stored in the storage box 29 below the seat 41, the storage box 29 can be used effectively. Since the floor board 45 is also located below the seat 41, the periphery of the battery 53 can also be used as the tread surface of the floor board 45.

[0034] In this embodiment, the battery is attached to and detached from the left side, but the direction in which the battery is attached to and detached from the battery holder is not particularly limited. For example, the battery may be attached to and detached from the front or right side of the battery holder.

[0035] In addition, in this embodiment, the battery is held in an inclined state in the battery holder, but the attitude in which the battery is held is not particularly limited. For example, the battery may be held in an upright attitude in the battery holder.

[0036] In this embodiment, a single battery is installed in the saddle riding type vehicle, but at least one battery may be installed in the saddle riding type vehicle. For example, the main battery and the sub-battery may be installed side by side in the saddle riding type vehicle. In this case, a main holder that detachably holds the main battery and a sub-holder that detachably holds the sub-battery are installed above the floor board.

[0037] In addition, in this embodiment, the battery holder is supported by a battery bracket that protrudes upward from the floor board, but the battery holder may be supported by a protruding portion other than the battery bracket. For example, a part of the floor board may protrude upward, and the battery holder may be supported by the protruding portion of the floor board.

[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 embodiment is a saddle-type vehicle (1) that can run on the power of a battery (53), and includes a low-floor board (45) on which the legs of a driver are placed, a seat (41) that covers the rear part of the floor board from above, and a battery holder (50) that detachably holds a battery, and the space between the seat and the floor board is exposed to the outside, and the battery holder is installed in the space and positioned above the floor board. According to this configuration, since the battery holder is exposed to the outside on the floor board, the battery can be easily attached and detached from the battery holder without opening and closing the seat. In addition, the battery is not stored in the storage box below the seat, and the storage box can be effectively used. Since the floor board is also located below the seat, the area around the battery can also be used as a tread surface for the floor board.

[0040] In the second aspect, the battery in the first aspect is tilted forward so that the upper end of the battery is located forward of the lower end. With this configuration, the lower end of the battery is positioned rearward, thereby making it possible to ensure a wide tread surface of the floorboard.

[0041] In the third aspect, the vehicle according to the first or second aspect includes a side frame (14) rising from the rear of the floor board, and the side frame is located rearward of the battery. With this configuration, the battery does not overlap the side frame in a side view. This makes it easier to expose the battery to the outside, improving the ease of attaching and detaching the battery.

[0042] In a fourth aspect, in the third aspect, the battery is inclined forward along the side frame. With this configuration, the battery is brought closer to the side frame, and a wide tread surface of the floor board can be secured.

[0043] In a fifth aspect, in any one of the first to fourth aspects, the entire battery holder is located forward of the rear end (47) of the floor board and inside both ends (48, 49) of the floor board in the vehicle width direction. With this configuration, the floor board protects the entire battery from water splashes, flying stones, and the like from below.

[0044] In a sixth aspect, in any one of the first to fifth aspects, the rear part of the floorboard is curved upward, and the battery is held in the battery holder so that the battery is higher than the rear upper surface of the floorboard. With this configuration, even if the rear part of the floorboard is curved upward, the battery does not interfere with the floorboard. The battery is installed on the curved rear side of the floorboard, and a wide tread surface of the floorboard can be secured.

[0045] 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.

[0046] 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]
