Description

Technical Field

[0001] This invention relates to a straddle-type vehicle. Prior Technology

[0002] Previous straddle-type vehicles, such as electric two-wheelers, have a frame, a battery pack disposed within the frame, and a storage compartment (see Patent Document 1). In the previous electric two-wheeler, the frame has a pair of upper frames and a pair of lower frames disposed below the upper frames. The battery pack is disposed below the upper frames and between the lower frames. The storage compartment is disposed further rearward than the battery pack.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2021-66291 Summary of the Invention

[0004] [The problem the invention aims to solve] Generally speaking, in recent years, electric two-wheelers have been striving to increase the size of the battery pack in order to ensure sufficient driving range. In previous electric two-wheelers, the battery pack was located lower than the pair of upper frames. Therefore, in the pursuit of larger battery packs, the size of the vehicle frame below the pair of upper frames may increase in the longitudinal direction.

[0005] Here, if the dimensions of the vehicle frame in the front-to-back direction are increased, the wheelbase becomes longer, and the drive motor unit is positioned further rearward. Therefore, maneuverability during driving may be reduced. On the other hand, if a larger battery pack is to be achieved without increasing the dimensions of the vehicle frame in the front-to-back direction, the storage space may become smaller. In this case, convenience may be compromised. That is, in previous electric two-wheelers, it was difficult to install a large battery pack in the vehicle frame without compromising maneuverability and convenience.

[0006] The purpose of this invention is to provide a straddle-type vehicle that can accommodate a large battery pack without compromising drivability and convenience. [Technical means to solve the problem]

[0007] One embodiment of the present invention comprises a straddle-type vehicle with a body frame, a pair of left and right footrests, a body shell, a battery pack, a storage section, and a drive motor unit. The body frame includes a head tube, a pair of left and right downward frames, a pair of left and right upper frames, a pair of left and right lower frames, and a pair of left and right seat frames.

[0008] A pair of downward-facing frames extend downwards from the head tube. A pair of upper left and right frames are positioned above the pair of downward-facing frames. A pair of lower left and right frames are positioned further below the pair of upper left and right frames. The pair of lower left and right frames extend rearwards from the pair of downward-facing frames. The pair of seat frames extend rearwards from the pair of upper left and right frames, supporting the seat.

[0009] The left and right footrests are positioned further forward and lower than the seat. At least a portion of the left and right footrests is positioned further outward in the left-right direction than the body frame. The body shell covers the body frame. The body shell includes an interior space. The interior space is formed between the head tube and the seat in the front-rear direction, and between the left and right footrests.

[0010] The battery pack is housed within the internal space. Its upper portion is positioned above the upper edges of the left and right upper frames. The battery pack is located between the left and right upper frames and between the left and right lower frames. The storage unit is positioned below the base, overlapping the upper portion of the battery pack in the front-to-back direction. The storage unit is located between the left and right base frames. The drive motor unit overlaps the lower portion of the battery pack in the front-to-back direction and is positioned directly below the storage unit. The drive motor unit is powered by the battery pack.

[0011] In this straddle-type vehicle, as described above, the battery pack is housed within the interior space. Therefore, even with a larger battery pack, there is no need to extend the length of the vehicle frame in the longitudinal direction, such as the wheelbase, thus ensuring better maneuverability during driving. This configuration effectively suppresses the expansion of the vehicle frame size in the longitudinal direction. In other words, this straddle-type vehicle can accommodate a large battery pack without compromising drivability and convenience.

[0012] This straddle-type vehicle can also be configured as follows: This straddle-type vehicle further includes a motor controller unit. The motor controller unit is located further rearward than the battery pack and further forward than the drive motor unit. The motor controller unit controls the drive motor unit. In this case, the space formed further rearward than the battery pack and further forward than the drive motor unit can be effectively utilized as the space for the motor controller unit.

[0013] This straddle-type vehicle can also be configured as follows: This straddle-type vehicle further includes a seat opening and closing mechanism. The seat opening and closing mechanism has a swinging part and a swing limiting part. The swinging part supports the seat, allowing it to swing relative to a pair of left and right seat frames. The swing limiting part allows or restricts the swinging of the seat relative to the pair of left and right seat frames.

[0014] Either the swinging part or the swing limiting part is provided on the front part of the seat part on a pair of left and right seat frames. At least one of the drive motor unit and the motor controller unit is disposed directly below the seat opening and closing structure.

[0015] In this case, the space below the seat opening and closing structure can be effectively utilized as space for at least one of the drive motor unit and the motor controller unit. In particular, since either the swing part or the swing limiting part is provided in the front part of the seat, the space below the seat opening and closing structure, such as the space below the front part of the seat, can be effectively utilized.

[0016] This straddle-type vehicle can also be configured as follows. This straddle-type vehicle further includes an electrical device. The electrical device is located directly below either the swing section or the swing limiting section, and directly above at least either the drive motor unit or the motor controller unit.

[0017] In this case, the electrical device is positioned between the swing section and the swing limiting section in the vertical direction and at least one of the drive motor unit and the motor controller unit, so that the space below the seat opening and closing structure, such as the space below the front part of the seat, can be effectively used as the space for the electrical device.

[0018] This straddle-type vehicle can also be configured as follows: This straddle-type vehicle further includes a unit support member. The unit support member supports at least one of the drive motor unit and the motor controller unit. The unit support member is detachably mounted to the vehicle frame after the battery pack. In this case, the drive motor unit can be removed from the vehicle frame without removing the battery pack from the vehicle frame.

[0019] This straddle-type vehicle can also be configured as follows: The unit support member is positioned lower than the storage section. In this case, the space below the storage section can be effectively utilized as space for the unit support member.

[0020] This straddle-type vehicle can also be configured as follows: This straddle-type vehicle further includes a motor controller unit. The motor controller unit is located further rearward than the battery pack and further forward than the drive motor unit. The motor controller unit controls the drive motor unit. Unit support members are located further rearward than the motor controller unit.

[0021] In this situation, the space between the battery pack and the drive motor unit in the rear-to-rear direction can be effectively used as space for the motor controller unit. Furthermore, by positioning the unit support member further rearward than the motor controller unit, the drive motor unit can be removed from the vehicle frame without removing the battery pack and the motor controller unit from the vehicle frame.

[0022] This straddle-type vehicle can also be configured as follows: The upper part of the motor controller unit is positioned above the upper surface of the drive motor unit. The unit support member is positioned further rearward than the upper part of the motor controller unit and above the upper surface of the drive motor unit.

[0023] In this case, the space formed further rearward than the upper part of the motor controller unit and higher than the upper surface of the drive motor unit can be effectively utilized as a space for unit support members.

[0024] This straddle-type vehicle can also be configured as follows: The unit support member is positioned lower than the storage section and higher than the drive motor unit. In this case, the space between the storage section and the drive motor unit in the vertical direction can be effectively utilized as the space for the unit support member.

[0025] This straddle-type vehicle can also be configured as follows: The drive motor unit has a recess for accommodating at least a portion of the unit support member. In this case, by accommodating the unit support member in the recess, the capacity of the storage section can be sufficiently ensured.

[0026] This straddle-type vehicle can also be configured as follows: The unit support member is positioned above the motor output shaft of the drive motor unit. In this case, the unit support member can be easily mounted to or removed from the vehicle frame.

[0027] This straddle-type vehicle can also be configured as follows. This straddle-type vehicle further includes a first mounting member and a fixing mechanism. The first mounting member is disposed on the vehicle frame behind the battery pack. The fixing mechanism is configured to allow the unit support member to be mounted to the first mounting member from the rear, and to allow the unit support member to be removed from the first mounting member from the rear. In this case, the fixing mechanism allows for easy mounting or removal of the unit support member from the first mounting member from the rear.

[0028] This straddle-type vehicle can also be configured as follows: This straddle-type vehicle further includes a pair of second mounting members. The pair of second mounting members are disposed on the unit support member. The pair of second mounting members are arranged opposite each other in the left-right direction. The portion of the drive motor unit mounted on the unit support member is disposed between the pair of second mounting members. In this case, the drive motor unit can be stably supported on the unit support member using a simple configuration.

[0029] This straddle-type vehicle can also be configured as follows: This straddle-type vehicle further includes a swing arm. The swing arm supports the rear wheel, enabling it to rotate. The vehicle frame further includes a rear frame that connects a pair of left and right lower frames and a pair of left and right seat frames respectively.

[0030] The swing arm is configured to swing relative to the rear frame. The swing axis of the swing arm is positioned higher than the motor output shaft of the drive motor unit. In this configuration, the swing arm can operate stably. [Effects of the Invention]

The right upper frame 14b extends rearward from the right lower frame 12b. The right upper frame 14b is positioned further inside the vehicle width direction than the right lower frame 13b.

[0041] As shown in Figure 3, the left-right spacing between the upper left frame 14a and the upper right frame 14b is narrower than the left-right spacing between the lower left frame 13a and the lower right frame 13b. Specifically, in the vehicle width direction (left-right direction), the left-right spacing between the outer sides of the upper left frame 14a and the upper right frame 14b is narrower than the left-right spacing between the outer sides of the lower left frame 13a and the lower right frame 13b.

[0042] As shown in Figures 1, 2A, and 2B, a pair of left and right reinforcing frames 17 extend from the head tube 11 backwards above a pair of left and right upper frames 14. The pair of left and right reinforcing frames 17 are respectively connected to the pair of left and right upper frames 14.

The right reinforcing frame 17b is connected to the upper right frame 14b.

[0044] From a top-down view of the vehicle, at least a portion of the outer edges of the left and right pair of reinforcing frames 17 are positioned further inward than the outer edges of the left and right pair of upper frames 14. In this embodiment, in the vehicle width direction (left-right direction), the outer edge of the left reinforcing frame 17a is positioned further inward than the outer edge of the left upper frame 14a. In the vehicle width direction (left-right direction), the outer edge of the right reinforcing frame 17b is positioned further inward than the outer edge of the right upper frame 14b.

[0045] From a top-down view of the vehicle, at least a portion of the outer edges of the left and right pair of reinforcing frames 17 are positioned further inward than the outer edges of the left and right pair of downward frames 12. In this embodiment, in the vehicle width direction (left-right direction), the outer edge of the left reinforcing frame 17a is positioned further inward than the outer edge of the left downward frame 12a. In the vehicle width direction (left-right direction), the outer edge of the right reinforcing frame 17b is positioned further inward than the outer edge of the right downward frame 12b.

[0046] As shown in Figures 2A, 2B, and 3, a pair of left and right seat frames 15 are connected to a pair of left and right upper frames 14. The pair of left and right seat frames 15 extend rearward and upward from the pair of left and right upper frames 14.

[0047] The left and right seat frames 15 include a left seat frame 15a and a right seat frame 15b. The left seat frame 15a extends rearward and upward from the upper left frame 14a. The right seat frame 15b extends rearward and upward from the upper right frame 14b.

[0048] As shown in Figures 2A and 2B, a pair of left and right rear frames 16 connect a pair of left and right lower frames 13 and a pair of left and right seat frames 15 respectively. Specifically, the pair of left and right rear frames 16 are connected to the pair of left and right lower frames 13, the pair of left and right upper frames 14, and the pair of left and right seat frames 15. The lower ends of the pair of left and right rear frames 16 are positioned further below the pair of left and right lower frames 13.

[0049] As shown in Figure 2B, the left and right rear frames 16 include a left rear frame 16a and a right rear frame 16b. The left rear frame 16a extends downward and forward from the left seat frame 15a. The lower end of the left rear frame 16a extends inward in the vehicle width direction. The rear end of the lower left frame 13a and the rear end of the upper left frame 14a are connected to the left rear frame 16a.

[0050] The right rear frame 16b extends downward and forward from the right seat frame 15b. The lower end of the right rear frame 16b extends inward in the vehicle width direction. The lower end of the right rear frame 16b connects to the lower end of the left rear frame 16a. The rear end of the lower right frame 13b and the rear end of the upper right frame 14b connect to the right rear frame 16b.

[0051] As shown in Figure 1, the steering mechanism 3 is rotatably supported on the vehicle frame 2. The steering mechanism 3 includes a front fork 21 and a handlebar assembly 22. The front fork 21 is rotatably supported on the head tube 11. The handlebar assembly 22 is connected to the upper end of the front fork 21. The front wheel 4 is rotatably supported on the front fork 21.

[0052] The seat 5 is positioned behind the head tube 11. The seat 5 is positioned above a pair of left and right seat frames 15. The seat 5 is supported by the pair of left and right seat frames 15.

[0053] As shown in Figure 4, the straddle-type vehicle 1 further includes a seat opening and closing structure 23. The seat opening and closing structure 23 is positioned higher than the drive motor unit 6. The seat opening and closing structure 23 has a swing shaft 24 (an example of a swing part) and a swing limiting part 25. The swing shaft 24 supports the seat 5 so that it can swing relative to a pair of left and right seat frames 15.

[0054] A swing shaft 24 is located at the rear of the seat 5 and is mounted on a pair of left and right seat frames 15. More specifically, the swing shaft 24 is located at the rear of the seat 5 and is mounted on a pair of left and right seat frames 15 via a bracket (not shown). The swing shaft 24 is also located at the rear of the seat 5 and is mounted on the vehicle body shell 9, for example, a pair of left and right rear shells 34 described later. The seat 5 is mounted on the swing shaft 24. By swinging the seat 5 around the swing shaft 24, the driver can store / retrieve the seat in the storage compartment 50 (described later).

[0055] The swing limiting part 25 allows or restricts the swing of the seat 5 relative to the left and right pair of seat frames 15. The swing limiting part 25 engages with the front part of the seat 5, allowing or restricting the swing of the seat 5. The swing limiting part 25 is provided at the front part of the seat 5 on the left and right pair of seat frames 15. The swing limiting part 25 may also be provided at the front part of the seat 5 on the vehicle body shell 9, such as the upper shell 35 described later.

[0056] When the swing limiting part 25 allows the seat 5 to swing, the seat 5 swings around the swing axis 24, causing the upper part of the storage box 50 to open. When the swing limiting part 25 restricts the swing of the seat 5, the seat 5 cannot swing around the swing axis 24, and the storage box 50 is closed.

[0057] As shown in Figure 4, the drive motor unit 6 is powered by the battery pack 10 and is driven by the battery pack 10. The drive motor unit 6 includes a drive motor. The drive motor unit 6 drives the rear wheel 7.

[0058] In a side view of the vehicle body, the drive motor unit 6 is positioned further rearward than the lower part of the battery pack 10. In other words, the drive motor unit 6 overlaps with the lower part of the battery pack 10 in the longitudinal direction. In this embodiment, the lower part of the battery pack 10 overlaps with the lower portion 10c (described later) of the battery pack 10 in the longitudinal direction. Furthermore, the lower part of the battery pack 10 overlaps with the central portion 10a (described later) of the battery pack 10 in the longitudinal direction.

[0059] The drive motor unit 6 is positioned directly below the storage box 50 when viewed from the side of the vehicle body. In other words, the drive motor unit 6 overlaps with the storage box 50 when viewed from above the vehicle body.

[0060] In a side view of the vehicle body, the drive motor unit 6 is positioned lower than the seat opening / closing structure 23. Specifically, in a side view of the vehicle body, the drive motor unit 6 is positioned lower than the swing shaft 24 and the swing limiting part 25. The drive motor unit 6 is positioned lower than the swing limiting part 25. Depending on the layout of the swing limiting part 25, the drive motor unit 6 may also be positioned directly below the swing limiting part 25. The drive motor unit 6 is supported on the vehicle body frame 2.

[0061] The drive motor unit 6 has a first mounting portion 6a, a second mounting portion 6b, and a recess 6c. The first mounting portion 6a is provided on the upper surface of the drive motor unit 6.

[0064] The motor controller unit 60 shown in Figures 3 and 4 is connected to the drive motor unit 6. The motor controller unit 60 controls the drive motor unit 6. The motor controller unit 60 receives power from the battery pack 10 and operates accordingly. The motor controller unit 60 is positioned further rearward than the battery pack 10 and further forward than the drive motor unit 6. That is, in the vehicle's longitudinal direction, the motor controller unit 60 is positioned between the battery pack 10 and the drive motor unit 6.

[0065] As shown in Figure 4, the upper part of the motor controller unit 60 is positioned higher than the upper surface of the drive motor unit 6. That is, in a side view of the vehicle, the upper part of the motor controller unit 60 protrudes from the upper surface of the drive motor unit 6. The motor controller unit 60 is positioned directly below the seat opening and closing structure 23. More specifically, the motor controller unit 60 is positioned directly below the swing limiting part 25 of the seat opening and closing structure 23.

[0066] As shown in Figures 4 and 5, the straddle-type vehicle 1 further includes a unit support member 27. The unit support member 27 supports at least one of the drive motor unit 6 and the motor controller unit 60. In this embodiment, the unit support member 27 supports both the drive motor unit 6 and the motor controller unit 60. More specifically, the unit support member 27 supports the drive motor unit 6 on which the motor controller unit 60 is mounted.

[0067] The unit support member 27 is positioned further rearward than the motor controller unit 60. Specifically, in a vehicle side view, the unit support member 27 is positioned above the upper surface of the drive motor unit 6 and further rearward than the upper part of the motor controller unit 60. More specifically, in a vehicle side view, the unit support member 27 is positioned directly rearward relative to the upper part of the motor controller unit 60. In other words, in a vehicle front view, the unit support member 27 overlaps with the upper part of the motor controller unit 60.

[0068] As shown in Figure 5, the unit support component 27 is detachably mounted on the vehicle frame 2 after the battery pack 10. The unit support component 27 is detachably mounted on a pair of left and right rear frames 16.

[0069] As shown in Figure 4, the unit support member 27 is positioned higher than the drive motor unit 6. The unit support member 27 is positioned higher than the motor output shaft P1 of the drive motor unit 6. A reducer (not shown) is connected to the motor output shaft P1. The symbol P3 in Figure 5 represents the output shaft of the reducer. The unit support member 27 is detachably mounted on a pair of left and right rear frames 16. Specifically, the unit support member 27 is a rod-shaped support member, and its two ends are detachably mounted on the left rear frame 16a and the right rear frame 16b, respectively.

[0070] As shown in Figure 5, the straddle-type vehicle 1 further includes a pair of first mounting members 65, a pair of first fixing mechanisms 66, a pair of second mounting members 67, and a second fixing mechanism 68. The pair of first mounting members 65 are disposed on the vehicle frame 2 behind the battery pack 10. Specifically, the pair of first mounting members 65 are respectively disposed on a pair of left and right rear frames 16, such as the left rear frame 16a and the right rear frame 16b.

[0071] A pair of first fixing mechanisms 66 are configured to allow the unit support member 27 to be mounted to a pair of first mounting members 65 from the rear. The first fixing mechanisms 66 are also configured to allow the unit support member 27 to be removed rearward from the pair of first mounting members 65. The first fixing mechanisms 66 are fixing bolts. The pair of first fixing mechanisms 66 are used to fix the unit support member 27 to the pair of first mounting members 65 from the rear of the unit support member 27.

[0072] A pair of second mounting members 67 are disposed on the unit support member 27. The pair of second mounting members 67 are arranged opposite each other in the left-right direction. The pair of second mounting members 67 can be integrally formed or separately formed. A first mounting portion 6a of the drive motor unit 6 is disposed between the pair of second mounting members 67. A second fixing mechanism 68 is a fixing bolt. The second fixing mechanism 68 is used to fix the first mounting portion 6a of the drive motor unit 6 to the pair of second mounting members 67.

[0073] As shown in Figure 5, the straddle-type vehicle 1 further includes a pair of third mounting members 69 and a third fixing mechanism 70. The pair of third mounting members 69 are disposed on the vehicle frame 2 behind the battery pack 10. Specifically, the pair of third mounting members 69 are disposed below a pair of left and right rear frames 16. The pair of third mounting members 69 are arranged opposite each other in the left-right direction. The pair of third mounting members 69 can be integrally formed or formed separately.

[0074] A second mounting portion 6b of the drive motor unit 6 is disposed between a pair of third mounting members 69. A third fixing mechanism 70 consists of fixing bolts and nuts. The third fixing mechanism 70 is used to fix the second mounting portion 6b of the drive motor unit 6 to the pair of third mounting members 69.

[0075] As shown in Figure 1, the rear wheel 7 is connected to the drive motor unit 6 and is driven by the drive motor unit 6. As shown in Figure 6, the swing arm 20 shown in Figure 1 includes a pair of left and right swing arms 20a and 20b. In Figure 6, the configuration on the right side is shown in parentheses. The pair of left and right swing arms 20a and 20b support the rear wheel 7, enabling it to rotate.

The vehicle body shell 9 includes a passage T.

[0082] The front outer shell 31 is fixed to the vehicle frame 2. The front outer shell 31 is positioned in front of the head tube 11 and the left and right pairs of downward frames 12. The front outer shell 31, the left and right pairs of front outer shells 32, and the left and right pairs of leg guards 33 cover the area around the head tube 11 and the left and right pairs of downward frames 12.

[0083] A pair of front outer shells 32 are positioned to the sides of the head tube 11 and the pair of downward-facing frames 12. A pair of leg guards 33 are positioned to the rear of the head tube 11 and the pair of downward-facing frames 12.

[0084] A pair of left and right rear outer shells 34 are disposed on the sides of a pair of left and right upper frames 14 and a pair of left and right seat frames 15. The pair of left and right rear outer shells 34 are disposed below the seat 5. The pair of left and right rear outer shells 34 are disposed above the pair of left and right lower frames 13. The pair of left and right rear outer shells 34 cover the pair of left and right lower frames 13 from above. The pair of left and right rear outer shells 34 include a pair of left and right footrests 8.

[0085] The left and right rear outer shells 34 comprise a left rear outer shell 34a and a right rear outer shell 34b. The left rear outer shell 34a covers the upper left frame 14a and the left seat frame 15a from the left. The left rear outer shell 34a also covers the lower left frame 13a from above. The right rear outer shell 34b covers the upper right frame 14b and the right seat frame 15b from the right. The right rear outer shell 34b also covers the lower right frame 13b from above.

[0086] The upper outer shell 35 is positioned between the head tube 11 and the seat 5 in the longitudinal direction of the vehicle. The upper outer shell 35 is positioned above the battery pack 10. In the width direction (left-right direction), the upper outer shell 35 is positioned between a pair of left and right rear outer shells 34.

[0087] As shown in Figure 1, the upper surface of the upper outer shell 35 is concave in a downward recessed manner. Specifically, the upper surface 35a of the upper outer shell 35 on the head tube 11 side is concave in a downward recessed manner. The upper surface 35b of the upper outer shell 35 on the seat 5 side is formed to have the same height as the upper surface 5a of the front part of the seat 5.

[0088] The bottom outer shell 36 is positioned below the pair of left and right lower frames 13. The bottom outer shell 36 covers the pair of left and right lower frames 13 from below. The bottom outer shell 36 is positioned below the pair of left and right rear outer shells 34. The bottom outer shell 36 is positioned below the pair of left and right footrests 8.

[0089] As shown in Figure 1, the passage T is an interior space surrounded by the vehicle body shell 9, located further forward than the front end of the seat 5 and further backward than the front end of the footrest 8 when viewed from the side of the vehicle.

[0090] The passage T is formed along the longitudinal direction of the vehicle. In the longitudinal direction, the passage T is formed between the head tube 11 and the seat 5. The passage T is formed rearward from the left lower frame 12a and the right lower frame 12b. In the width direction (left-right direction), the passage T is formed between the left and right footrests 8. The passage T is formed between the left and right leg guards 33 and the seat 5.

[0091] As shown in Figure 8, the channel T is positioned in the center of the vehicle in the vehicle width direction (left-right direction). The channel T is formed in the vehicle width direction between the lower left frame 13a and the lower right frame 13b, and between the upper left frame 14a and the upper right frame 14b.

[0092] The lower left frame 13a is positioned further outward than the upper left frame 14a in the vehicle width direction, and the lower right frame 13b is positioned further outward than the upper right frame 14b in the vehicle width direction. Therefore, the width below the channel T is wider than the width above it. In Figure 8, the charger 42, cooling unit 43, and battery pack 10 are shown in a simplified manner for easy understanding.

[0093] The passageway T is the area surrounded by the left rear outer shell 34a and right rear outer shell 34b, the upper outer shell 35, the left footrest 8a, the right footrest 8b, and the lower outer shell 36. That is, the passageway T covers the left and right lower frames 13 and the left and right upper frames 14 from the outside in the vehicle width direction. The passageway T covers the left and right upper frames 14 from above. The passageway T covers the left and right lower frames 13 from below.

[0094] The battery pack 10 is disposed in the passageway T. The battery pack 10 is housed in the passageway T. The battery pack 10 is disposed in front of and below the seat 5. The battery pack 10 is disposed in the center of the vehicle in the width direction (left-right direction). The battery pack 10 is disposed between the left and right footrests 8.

[0095] The battery pack 10 is disposed between a pair of left and right upper frames 14. The upper part of the battery pack 10, for example, the upper surface of the battery pack 10, is disposed above the upper edge of the pair of left and right upper frames 14. The battery pack 10 is disposed between a pair of left and right lower frames 13. The lower part of the battery pack 10, for example, the lower surface of the battery pack 10, is disposed below the lower edge of the pair of left and right lower frames 13.

[0096] As shown in Figure 4, the front surface of the battery pack 10 is positioned further rearward than the pair of downward-facing left and right frames 12. The rear surface of the battery pack 10 is positioned further forward than the pair of rear left and right frames 16.

[0097] As shown in Figures 2A, 2B and 8, the battery pack 10 includes a central part 10a, an upper part 10b and a lower part 10c.

[0098] The central portion 10a is located in the center of the battery pack 10 in the vertical direction. The central portion 10a forms the central portion of the battery pack 10 in the vertical direction. The central portion 10a is disposed between a pair of upper left and right frames 14 and a pair of lower left and right frames 13 in the vertical direction.

[0099] The upper part 10b is located above the battery pack 10 in the vertical direction. The upper part 10b is located higher than the central part 10a in the vertical direction. The upper part 10b forms the upper part of the battery pack 10 in the vertical direction. The upper part 10b is disposed between a pair of left and right upper frames 14.

[0100] The lower part 10c is located below the battery pack 10 in the vertical direction. The lower part 10c is positioned lower than the central part 10a in the vertical direction. The lower part 10c forms the lower portion of the battery pack 10 in the vertical direction. The lower part 10c is positioned between a pair of left and right lower frames 13. The lower surface of the lower part 10c is positioned lower than the pair of left and right lower frames 13.

[0101] As shown in Figure 8, in the battery pack 10, the width of the upper part 10b is smaller than the width of the central part 10a. As shown in Figure 3, the width of the front end 10b1 of the upper part 10b is smaller than the width of the central part 10b2 in the front-rear direction of the upper part 10b. Furthermore, in this embodiment, the term "width" refers to the width in the vehicle width direction (left-right direction).

[0102] As shown in Figure 8, the width of the lower part 10c is smaller than the width of the central part 10a. Specifically, the width of the portion of the lower part 10c located below the left and right lower frames 13 is smaller than the width of the central part 10a. Therefore, even if the size of the battery pack 10 increases, the tilt angle of the straddle-type vehicle 1 can still be achieved.

[0103] As shown in Figure 4, the straddle-type vehicle 1 further includes a storage box 50 (an example of a storage unit). The storage box 50 is mounted on the vehicle body frame 2. The storage box 50 is mounted on a pair of left and right seat frames 15 (left seat frame 15a and right seat frame 15b).

[0104] As shown in Figure 4, the storage box 50, viewed from the side of the vehicle, is positioned below the seat 5 and further rearward than the upper part of the battery pack 10. In other words, the storage box 50 is positioned below the seat 5 such that it overlaps with the upper part of the battery pack 10 in the front-rear direction. In this embodiment, the storage box 50 is positioned below the seat 5 such that it overlaps with the upper part 10b of the battery pack 10 in the front-rear direction. Furthermore, the storage box 50 is positioned below the seat 5 such that it overlaps with the upper part of the central part 10a of the battery pack 10 in the front-rear direction.

[0105] The storage box 50 is positioned above the drive motor unit 6 when viewed from the side of the vehicle body. The storage box 50 is positioned above the unit support member 27. The storage box 50 is positioned between the left and right seat frames 15 (left seat frame 15a and right seat frame 15b).

[0106] As shown in Figures 2A and 2B, the straddle-type vehicle 1 further includes a first bracket 37 and a second bracket 38. The first bracket 37 supports the battery pack 10, for example, the central portion 10a of the pack. The first bracket 37 includes a pair of left and right first brackets 37. The pair of left and right first brackets 37 are used to mount the battery pack 10 to a pair of left and right upper frames 14.

[0107] The first bracket 37 consists of a first left bracket 37a and a first right bracket 37b. The first left bracket 37a is installed on the left side of the upper left frame 14a and the battery pack 10. The first right bracket 37b is installed on the right side of the upper right frame 14b and the battery pack 10.

[0108] The first right bracket 37b is configured symmetrically with respect to the vehicle centerline in the vehicle width direction (left-right direction) to the first left bracket 37a. Therefore, in Figure 2A, the symbol 37b of the first right bracket is shown in parentheses within the symbol 37a of the first left bracket.

[0109] As shown in Figures 2A and 2B, the second bracket 38 supports the battery pack 10, for example, the lower part 10c of the pack. The second bracket 38 comprises a plurality of second brackets 38. The plurality of second brackets 38 are used to mount the battery pack 10 to a pair of left and right lower frames 13.

[0110] A plurality of second brackets 38, for example two second brackets 38, are respectively mounted on a pair of left and right lower frames 13. The two second brackets 38 are respectively mounted on the lower surface of the battery pack 10. In this way, the battery pack 10 is suspended from the pair of left and right lower frames 13 via the two second brackets 38.

[0111] As shown in Figure 8, each of the two second brackets 38 extends downward from the mounting point of the front wheel 4 along a pair of straight lines L1 and L2 tangent to the outer surfaces of the left and right lower frames 13, when viewed from the front of the vehicle. Each of the two second brackets 38 extends along the lower surface of the battery pack 10 in the vehicle width direction (left-right direction). This configuration prevents the straddle-type vehicle 1 from contacting the two second brackets 38 and the ground when tilted.

[0112] As shown in Figures 2B and 9, the straddle-type vehicle 1 further includes an external power connection 41, a charger 42, a cooling unit 43, a voltage converter 44 (an example of an electrical device), and a radiator 45. The external power connection 41 is connected to an external power source for charging. The charger 42 supplies current to the battery pack 10. Specifically, the charger 42 converts the alternating current supplied from the external power connection 41 into direct current and supplies the direct current to the battery pack 10.

[0113] As shown in Figures 2A and 2B, the charger 42 is disposed on the upper part of the battery pack 10. Specifically, the charger 42 is located at the rear of the battery pack 10, on the upper surface of the battery pack 10. The charger 42 is disposed higher than the pair of upper left and right frames 14. As shown in Figure 8, in the vehicle width direction (left-right direction), the charger 42 is disposed between the upper left frame 14a and the upper right frame 14b.

[0114] As shown in Figure 9, when viewed from the front of the vehicle, the charger 42 is configured to overlap at least partially with the head tube 11. As shown in Figures 4 and 8, the charger 42 is covered from above by the upper housing 35. The charger 42 is positioned in front of the storage box 50.

[0115] As shown in Figure 4, the cooling unit 43 cools the charger 42. The cooling unit 43 is an air-cooled cooler. The cooling unit 43 is connected to the charger 42. The cooling unit 43 is configured such that air passes from the front of the cooling unit 43 to the rear of the cooling unit 43. The cooling unit 43 is located at the rear of the battery pack 10, above the battery pack 10. More specifically, the cooling unit 43 is disposed on the upper surface of the charger 42.

[0116] In the cooling section 43, firstly, air is drawn in from the front of the housing by a cooling fan. Then, this air exchanges heat with the charger 42 via cooling fins connected to the charger 42. In this way, the charger 42 is cooled. Afterward, the air is discharged from the rear of the housing of the cooling section 43 to the outside of the housing. Alternatively, the cooling section 43 may not have a cooling fan, and may only use cooling fins to cool the charger 42.

[0117] The voltage converter 44 shown in Figure 2B reduces the voltage input from the battery pack 10. As shown in Figure 4, the voltage converter 44 is positioned further rearward than the battery pack 10. The voltage converter 44 is located on the upper surface side of the battery pack 10. [ ]

[0118] In detail, the voltage converter 44 is positioned above the drive motor unit 6. The voltage converter 44 is positioned above the motor controller unit 60. The voltage converter 44 is positioned below the seat opening and closing structure 23. Specifically, the voltage converter 44 is positioned below the swing limiting part 25 of the seat opening and closing structure 23.

[0119] The radiator 45 shown in Figures 2A, 3, and 9 is used to cool the drive motor unit 6. The drive motor unit 6 is cooled by cooling water passed through the radiator 45. The radiator 45 is positioned further forward than the battery pack 10. As shown in Figures 2A and 9, in a frontal view of the vehicle, the radiator 45 overlaps with the battery pack 10. Specifically, as shown in Figure 2A, in a frontal view of the vehicle, the radiator 45 overlaps with the upper portion 10b of the battery pack 10.

[0120] In the straddle-type vehicle 1 of this embodiment described above, the battery pack 10 is arranged in the passageway T as described above. Therefore, even if the battery pack 10 is made larger, it is not necessary to extend the length of the vehicle frame 2 in the longitudinal direction, such as the wheelbase, thus ensuring better maneuverability during driving. With this configuration, the size of the vehicle frame 2 in the longitudinal direction can be suppressed. That is, in the straddle-type vehicle 1, a large battery pack 10 can be installed without compromising drivability and convenience.

[0121] In the straddle-type vehicle 1, the space formed further rearward than the battery pack 10 and further forward than the drive motor unit 6 can be effectively utilized as the space for the motor controller unit 60.

[0122] In the straddle-type vehicle 1, the space below the seat opening and closing structure 23 can be effectively utilized as the space for the drive motor unit 6 and the motor controller unit 60. In this embodiment, the space below the front part of the seat 5, for example, the space below the swing shaft 24, can be effectively utilized as the space for the motor controller unit 60.

[0123] In the straddle-type vehicle 1, the voltage converter 44 is disposed between the swing shaft 24 and the motor controller unit 60 in the vertical direction, so the space below the front part of the seat 5, such as the space below the swing shaft 24, can be effectively utilized as the space for the voltage converter 44.

[0124] In the straddle-type vehicle 1, the unit support member 27 is detachably mounted on the vehicle frame 2 after the battery pack 10, so the drive motor unit 6 can be removed from the vehicle frame 2 without removing the battery pack 10 from the vehicle frame 2.

[0125] In the straddle-type vehicle 1, the space below the storage box 50 can be effectively utilized as the space for the unit support member 27.

[0126] In the straddle-type vehicle 1, the space between the battery pack 10 and the drive motor unit 6 in the rear-to-rear direction can be effectively utilized as the space for the motor controller unit 60. Furthermore, by positioning the unit support member 27 further rearward than the motor controller unit 60, the drive motor unit 6 can be removed from the vehicle frame 2 without removing the battery pack 10 and the motor controller unit 60 from the vehicle frame 2.

[0127] In the straddle-type vehicle 1, the space formed at a rearward position above the motor controller unit 60 and above the upper surface of the drive motor unit 6 can be effectively utilized as the space for the unit support member 27.

[0128] In the straddle-type vehicle 1, the space between the storage box 50 and the drive motor unit 6 in the vertical direction can be effectively used as the space for the unit support member 27.

[0129] In the straddle-type vehicle 1, by housing at least a portion of the unit support member 27 in the recess 6c, the capacity of the storage box 50 can be adequately ensured.

[0130] In the straddle-type vehicle 1, the unit support member 27 is positioned above the motor output shaft P1 of the drive motor unit 6, so that the unit support member 27 can be easily installed on or removed from the vehicle frame 2.

[0131] In the straddle-type vehicle 1, the unit support member 27 can be easily installed on or removed from the first mounting member 65 from the rear by means of the first fixing mechanism 66.

[0132] In the straddle-type vehicle 1, the first mounting part 6a of the drive motor unit 6 is disposed between a pair of second mounting members 67, so the drive motor unit 6 can be stably supported on the unit support member 27 with a simple configuration.

[0133] In the straddle-type vehicle 1, the swing shaft of the swing arm 20 is positioned higher than the motor output shaft P1 of the drive motor unit 6, thus enabling the swing arm 20 to move stably.

[0134] The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment and various modifications can be made without departing from the spirit of the invention.

[0135] In the above embodiments, the channel T is formed such that its width increases as it faces downwards, but it is not limited to this and may also have the same width in the vertical direction.

[0136] In the above embodiment, the swing shaft 24 is disposed at the front part of the seat 5 and the swing limiting part 25 is disposed at the rear part of the seat 5. However, it is not limited to this. The swing limiting part 25 can also be disposed at the front part of the seat 5 and the swing shaft 24 can be disposed at the rear part of the seat 5.

[0137] In the above embodiment, the external power connection part 41 is disposed on the left side of the head tube 11, but it is not limited to this and may also be disposed on the right side.

[0138] In the above embodiments, the charger 42 is disposed on the upper surface of the battery pack 10. However, the charger 42 may not be directly disposed on the upper surface of the battery pack 10, or it may be disposed with other components between it and the upper surface of the battery pack 10.
