Description

Technical Field

[0001] This disclosure relates to a straddle-type vehicle having a structure that prevents water from entering the case housing space. Background Technology

[0002] Patent Document 1 discloses an electric straddle-type vehicle whose drive wheels are driven by a motor. The straddle-type vehicle is equipped with a battery housing. A cover is provided on the battery housing, allowing the opening of the battery housing to be opened and closed for removing and inserting the battery.

[0003] Existing technical documents: Patent documents: Patent document 1: International Publication No. 2015 / 068753. Summary of the Invention

[0004] The problem the invention aims to solve: In the structure disclosed in Patent Document 1, rainwater can easily enter the battery casing because an opening is formed for taking out and putting in the battery.

[0005] Therefore, the purpose of this disclosure is to provide a straddle vehicle capable of suppressing water intrusion into the opening.

[0006] Solution methods: The presently disclosed straddle-type vehicle comprises: a base having opposing portions surrounding a base opening that opens upwards to accommodate space; an outer cover configured to open and close the base opening; a protruding member disposed on one of the outer cover or the base, located outside the base opening, and protruding vertically toward the other of the outer cover or the base; and an outer wall disposed on either the outer cover or the base, facing the protruding member from the outside and located between the outer cover and the opposing portions in the vertical direction; the opposing portions are inclined relative to the horizontal direction, and the outer wall has drainage channels formed from the inside to the outside at a position lower than the upper end of the opposing portions.

[0007] Invention effects: According to this disclosure, the outer wall is located between the opposing portions of the outer cover and the base in the vertical direction, thus preventing water from entering through the base opening through both the outer wall and the protruding member. Furthermore, it is considered that water may exceed the outer wall and enter between the outer wall and the protruding member. In this case, the water also moves downwards due to the inclination of the opposing portions and flows out to the outside through the drainage channel formed on the outer wall. This prevents water from intruding into the receiving space. Attached Figure Description

Detailed Implementation

[0009] Hereinafter, the implementation of the straddle-type vehicle will be described with reference to the accompanying drawings. In this specification, the front-to-back direction, the left-to-right direction (lateral direction), and the up-down direction refer to the directions observed by the rider when the rider is seated on the vehicle.

[0010] Figure 1 This is a side view of the straddle-type vehicle (vehicle) 1 according to the implementation method. (Example) Figure 1 As shown, in this embodiment, the straddle vehicle 1 is a motorcycle.

[0011] The straddle-type vehicle 1 includes a front wheel 2, a rear wheel 3, and a frame 4. The frame 4 is supported by the front wheel 2 and the rear wheel 3. The straddle-type vehicle 1 has a front fork 5 connecting the front wheel 2 and the frame 4 and disposed between the front wheel 2 and the frame 4. The front fork 5 is disposed below the steering axle 7 and connected to a bracket 8 spaced apart in the vertical direction. The front fork 5 extends upward and rearward at an angle. A front suspension body 6 is disposed on the front fork 5, and the front fork 5 is configured to extend and retract along its length by the elastic deformation of a spring inside the front suspension body 6. The front fork 5 mitigates the impact transmitted to the frame 4 by extending and retracting along its length. The steering axle 7, connected to the bracket 8, is supported by a head tube 4a, which is part of the frame 4, in a manner that allows angular displacement. Furthermore, the straddle-type vehicle 1 has a rear suspension body 9 connecting the rear wheel 3 to the rear of the frame 4. In addition, a rocker arm 10, supporting the rear wheel 3 and extending in the longitudinal direction, is supported by the frame 4 in a manner that allows angular displacement.

[0012] A handlebar 11 for the rider to hold is provided on the steering shaft 7. A cover 53 covering the battery insertion port is provided behind the handlebar 11. A seat 12 for the rider to sit on is provided behind the cover 53. The straddle-type vehicle 1 is equipped with an electric motor M as a drive source to generate power transmitted to the wheels. The electric motor M is mounted on the frame 4 between the front wheel 2 and the rear wheel 3. In this embodiment, the electric motor M functions as a prime mover, generating rotational driving force transmitted to the rear wheel 3.

[0013] The straddle-type vehicle 1 includes a battery 14 and a housing 13 that houses the battery 14. The battery 14 is configured to store electricity supplied to electrical components. Furthermore, in this embodiment, the battery 14 supplies power to an electric motor M. Thus, the electric motor M is driven, and the straddle-type vehicle 1 moves. The battery 14 is connected to the electric motor M via wires. The housing 13 is mounted on the vehicle body frame 4.

[0014] The electric motor M has a motor housing Ma and a motor drive shaft Mb protruding from the motor housing Ma. A sprocket 16 is mounted on the motor drive shaft Mb and rotates together with it. Alternatively, a gear or pulley can be used instead of the sprocket 16 as a rotating component. A chain 17 is connected to the sprocket 16 on the motor drive shaft Mb side. Thus, the driving force output from the motor drive shaft Mb is transmitted to the rear wheel 3 via the chain 17. Alternatively, the driving force output from the motor drive shaft Mb can be transmitted to the rear wheel 3 not by a chain, but by other power transmission components such as a belt.

[0015] In this embodiment, an ECU (Electronic Control Unit) 39 is disposed at the front of the housing 13. The ECU 39 regulates the power supplied from the battery 14 to the electric motor M via the BMU (Battery Management System) and inverter, thereby controlling the drive of the electric motor M. The throttle device 18 is operated by the rider, and the drive of the electric motor M is controlled according to the rider's operation.

[0016] When a rider is driving a motorcycle 1, and the road surface or other unevenness causes an impact on the motorcycle, the front fork 5 extends and retracts along its length. The front suspension 6 extends and retracts to mitigate the impact transmitted to the frame 4, thereby reducing the impact on the rider. This improves the rider's riding comfort.

[0017] Furthermore, the straddle-type vehicle 1 includes a front fender 19 connected to the front fork 5 and moving up and down with the front fork 5 as the front fork 5 extends and retracts. In this embodiment, the front fender 19 protrudes from the front fork 5 in the front-rear direction and is mounted on the front fork 5 to cover the upper side of the front wheel 2.

[0018] In this embodiment, the straddle-type vehicle 1 is equipped with a side stand 20. When the straddle-type vehicle 1 is parked and stands upright using the side stand 20, it tilts towards the side where the side stand 20 is installed, thereby tilting the vehicle body.

[0019] Figure 2 The image shows a cross-sectional view of the area surrounding the casing, taken along a plane extending in the front-rear direction, with the outer cover 53 open and the inner cover 42, which covers the battery 14 on the inside of the outer cover 53, removed. Furthermore, Figure 3 The image shows a cross-sectional view of the area surrounding the housing, cut along a plane extending in the front-rear direction, with the outer cover 53 closed and the inner cover 42 covering the battery 14 installed inside the outer cover 53.

[0020] like Figure 2 and Figure 3As shown, the housing 13 is configured as a frame capable of accommodating the battery 14. The housing 13 defines a receiving space 25 for accommodating the battery 14. In this embodiment, the housing 13 has receiving spaces 25 corresponding to two batteries 14a and 14b, for accommodating the two batteries 14a and 14b. Furthermore, the housing 13 has: an inner bottom wall 28 that slopes downward toward the rear; and a peripheral wall 29 that extends upward from the inner bottom wall 28 and surrounds the receiving space 25. In addition, the housing 13 includes a housing opening 21 that opens the receiving space 25 of the battery 14 upward for removing and inserting the battery 14. When installed in the straddle-type vehicle 1, the housing 13 is inclined relative to the vertical direction with the housing opening 21 angled upward and rearward. That is, the housing 13 is installed in the straddle-type vehicle 1 with a rearward tilt as it moves upward from the lower end.

[0021] The housing 13's accommodating space 25 is configured such that the area of ​​the cross-section orthogonal to the insertion direction of the battery 14 decreases as it faces downward. In this embodiment, the housing 13 is configured such that the front and rear sides of the inner surface of the housing 13 are sloped together as they face downward. The housing 13 is configured such that, on its inner surface, the upper part provided with a step 22 and the lower part 24 configured as a slope face inward as it faces downward.

[0022] In addition, such as Figure 2 As shown, the bottom of the housing 13 is configured with a double-layer bottom structure 35. The double-layer bottom structure 35 of the bottom of the housing 13 has an inner bottom wall 28, an outer bottom wall 48 covering the inner bottom wall 28 from below, and a peripheral wall 30 connecting the outer bottom wall 48 and the inner bottom wall 28. The inner bottom wall 28 is installed at an angle on the straddle vehicle 1 along with the housing 13, and in the state of being installed on the straddle vehicle 1, it is inclined downward as it faces rearward. A connector 31 is provided on the inner bottom wall 28 of the housing 13, protruding inward toward the receiving space 25. In this embodiment, two connectors 31 are provided corresponding to the first battery 14a and the second battery 14b mounted on the housing 13.

[0023] A wiring connection for the connector 31 is disposed in the lower space 33 between the outer bottom wall 48 and the inner bottom wall 28 in the double-bottom structure 35 of the housing 13. In this embodiment, the lower space 33 is adjacent to the receiving space 25 outside the receiving space 25, separated by the inner bottom wall 28.

[0024] The wiring connected to connector 31 passes through the interior of the lower space 33, extends from the rear of the lower space 33 to the outside, and extends rearward. The wiring passes through the interior of the inner bottom wall 28 of the housing 13 from connector 31, extends downward into the lower space 33, passes through the interior of the lower space 33 and extends rearward to the outside of the housing 13. In this embodiment, the outer bottom wall 48 and the peripheral wall 30 are independently constructed from the inner bottom wall 28. Furthermore, the outer bottom wall 48 and the peripheral wall 30 constitute a one-piece cover 36. In this embodiment, the lower space 33 is divided between the inner bottom wall 28 and the cover 36.

[0025] The battery 14 has an output terminal 32 that connects to the connector 31 when the battery 14 is housed in the receiving space 25 of the housing 13. In this embodiment, the output terminal of the first battery 14a is designated as output terminal 44, and the output terminal of the second battery 14b is designated as output terminal 45. These output terminals 44 and 45 are collectively referred to as output terminal 32. The connector 31 of the housing 13 is connected to the output terminal 32 of the battery 14, enabling power from the battery 14 to be supplied to the electric motor M, etc., via wiring.

[0026] like Figure 2 As shown, the housing 13 accommodates two batteries 14a and 14b, and therefore has a partition 41 protruding from the inner bottom wall 28 of the housing 13 toward the inner side of the accommodating space 25 to separate the accommodating space for the two batteries 14 arranged in the width direction of the straddle vehicle 1. By using the partition 41 to separate the space for each of the two batteries 14a and 14b, each battery 14a and 14b can be arranged in a suitable position.

[0027] The straddle-type vehicle 1 has an inner cover 42 disposed above the housing 13. For example... Figure 3 As shown, an inner cover 42 that closes the housing opening 21 is installed on the housing 13. The inner cover 42 covers the battery 14 after it is housed in the housing 13, protecting the battery 14. In this embodiment, the inner cover 42 is fixed relative to the housing 13 by fastening screws.

[0028] like Figure 2 and 3 As shown, in this embodiment, the housing 13 is mounted adjacent to the electric motor M on the straddle-type vehicle 1 at a position in front of the electric motor M. The housing 13 is positioned between the front fork 5 and the electric motor M in the longitudinal direction of the straddle-type vehicle 1. In this embodiment, as described later, the housing 13 is arranged at an angle.

[0029] like Figure 3As shown, the battery 14 is housed in the housing space 25. When the inner cover 42 is installed above the battery 14, the inner cover 42 is configured to abut against the upper end 43 of the battery 14. With the battery 14 housed in the housing 13, the battery 14 abuts against the inner cover 42, thus pressing the battery 14 inside the housing 13. During the movement of the straddle-type vehicle 1, the battery 14 is also pressed down by the inner cover 42, thus preventing the battery 14 from moving vertically even when forces act vertically on the straddle-type vehicle 1 during movement. In this embodiment, the housing 13 is disposed between the front wheel 2 and the rear wheel 3, thereby providing the housing space 25 between the front wheel 2 and the rear wheel 3. Furthermore, in this embodiment, the housing 13 is disposed between the head tube 4a and the seat 12, thereby providing the housing space 25 between the head tube 4a and the seat 12.

[0030] In this embodiment, as described above, the housing 13 is mounted to the vehicle frame 4 at an angle to the rear as it moves upward from the lower end. This creates space in front of the housing 13 where an object can be placed. In this embodiment, the ECU 39 is disposed within the space created in front of the housing 13. Therefore, the space within the straddle-type vehicle 1 can be utilized efficiently. Furthermore, by disposing the ECU 39 in front of the housing 13, the ECU 39 can be placed in a space directly exposed to the driving airflow. Therefore, the ECU 39 can be efficiently cooled using the driving airflow. In particular, the ECU 39 tends to heat up during the movement of the straddle-type vehicle 1; therefore, by cooling the ECU 39 using the driving airflow, the temperature of the ECU 39 can be kept at a suitable temperature even while the straddle-type vehicle 1 is in motion.

[0031] The straddle-type vehicle 1 has a base 52 above the housing 13. The base 52 is positioned above the inner cover 42 in front of the seat 12. The base 52 is mounted above the housing 13 in a manner that surrounds the housing opening 21 and defines a portion of the receiving space 25. That is, in this embodiment, the space inside the base 52 and the space inside the housing 13 are collectively referred to as the receiving space 25. The base 52 has an opposing portion 60 located around the base opening 52a, which opens the receiving space 25 inside the base 52 upward. The opposing portion 60 is formed outside the base opening 52a and is formed in a closed loop shape around the base opening 52a. A surface is formed on the opposing portion 60 that is adjacent to the base opening 52a radially outward and faces upward. Furthermore, an opposing surface, described later, is provided on the opposing portion 60, which faces the outer cover 53 from below when the outer cover 53 is closed. A non-facing surface 52b is provided on the base 52, and a non-facing surface 52c is formed on the outer side of the facing surface and protrudes from the outer cover 53. The non-facing surface 52c is formed as a closed loop around the facing surface. The non-facing surface 52c becomes part of the appearance surface constituting the exterior of the straddle-type vehicle 1.

[0032] When the battery 14 is housed inside the housing 13 of the straddle-type vehicle 1, it is protected by the housing 13, the inner cover 42, and the outer cover 53, and the top of the battery 14 is double-covered by the inner cover 42 and the outer cover 53. In this embodiment, the base 52 is mounted on the flange 67 provided at the upper end of the peripheral wall 29 of the housing 13. Furthermore, in this embodiment, the base 52 is partially embedded in the cover 50 of the straddle-type vehicle 1 at a position in front of the seat 12, and the portion protruding from the cover 50 constitutes the outer surface of the straddle-type vehicle 1.

[0033] Furthermore, the straddle-mounted vehicle 1 has an outer cover 53 capable of opening and closing the base opening 52a. In this embodiment, the outer cover 53 is mounted on the outer cover mounting portion 51 formed on the base 52. The housing 13 is configured to be located between the rider's legs when the rider straddles the seat 12. The upper end 53a of the outer cover 53 protrudes upward relative to the seat 12.

[0034] The outer cover mounting portion 51 of the base 52 has a hinge portion 54 that rotatably connects the outer cover 53 relative to the base 52. The outer cover 53 opens and closes the base opening 52a by rotating the outer cover 53 around the hinge portion 54. The outer cover 53 protrudes outward and is configured as an exterior design part constituting the body exterior of the strut vehicle 1. In other words, the component that covers the outer cover 53 from the outside is not provided in the strut vehicle 1.

[0035] Figure 4 The image shows a perspective view of the base 52 and housing 13 cut along a plane extending in the front-rear direction and orthogonal to the horizontal plane with the outer cover 53 closed. Figure 4 As shown, the straddle-type vehicle 1 includes a protruding member for preventing water from entering the containment space 25. The protruding member is provided on the outer cover 53, facing the opposing portion 60 of the base 52, and protrudes downward from the outer cover 53. The protruding member is located outside the base opening 52a. In other words, the protruding member is located around the base opening 52a in a manner that surrounds the outer side of the base opening 52a. In this embodiment, when the outer cover 53 is closed, the protruding member is implemented by a sealing member 61 that blocks the space between the outer cover 53 and the opposing portion 60. In this embodiment, when the outer cover 53 is closed, the sealing member 61 is mounted on the outer edge of the outer cover 53 facing the base opening 52a. The sealing member 61 is mounted on the outer cover 53 in a manner that protrudes from the outer cover 53 toward the opposing portion 60. When the outer cover 53 is closed, the sealing member 61 is mounted on the opposing portion 60. In this embodiment, the sealing member 61 is formed of a flexible material and is configured to be deformable. The sealing member 61 deforms and blocks the space between the opposing part 60 and the outer cover 53, thereby blocking the vertical gap between the opposing part 60 and the outer cover 53.

[0036] A base space 40, which is part of the receiving space 25, is provided inside the base 52. The base space 40 serves as a passage for the battery 14 when it is removed and inserted into the housing 13. The base space 40 is located above the housing 13 along the insertion direction in which the battery 14 is inserted toward the housing 13. When the outer cover 53 is open and the inner cover 42 is open, the battery 14 can be received in the receiving space 25 of the housing 13 by passing through the base space 40. When the inner cover 42 is closed, the base space 40 includes the space above the inner cover 42.

[0037] When the battery 14 is housed in the casing 13, as Figure 2 As shown, the outer cover 53 covering the base space 40 is opened. If the outer cover 53 is opened, the inner cover 42 on top of the housing 13 is removed. If the outer cover 53 is opened and the inner cover 42 is removed, it is possible to enter the interior of the housing 13's receiving space 25 from the outside. The battery 14 passes through the base space 40 of the base 52, through the housing opening 21 of the housing 13, and is received in the housing 13's receiving space 25. Then, as... Figure 3 As shown, with the battery 14 contained in the housing space 25 of the housing 13, the inner cover 42 is installed on top of the housing 13, and the outer cover 53 closes the base space 40, thereby completing the housing of the battery 14 into the housing 13.

[0038] As described above, an opposing portion 60 is provided at the innermost radial position of the base 52 in the form of a base opening 52a facing the base 52. When the outer cover 53 is closed, a sealing member 61 is installed on the outer cover 53 in such a way that it abuts against the opposing portion 60.

[0039] The base 52 has an outer wall 62 located outside the sealing member 61. The outer wall 62 is formed adjacent to the contact portion 60g where the sealing member 61 abuts against the opposing portion 60. With the outer cover 53 closed, the outer wall 62 is located outside the sealing member 61, between the outer cover 53 and the opposing portion 60 in the vertical direction. In other words, the outer wall 62 is formed within the space surrounded by the outer cover 53 and the opposing portion 60. The outer wall 62 protrudes upward beyond the contact portion 60g where the sealing member 61 abuts against the opposing portion 60. Furthermore, the outer wall 62 protrudes upward beyond the lower end of the outer cover 53 located outside it. In other words, the outer cover 53 includes a lower position 53d that covers the outer wall 62 from the outside. Thus, by forming a labyrinth structure with the outer cover 53 and the outer wall 62, water intrusion is easily prevented. Furthermore, a vertical gap is formed between the outer wall 62 and the outer cover 53. This prevents the sealing member 61 from weakening due to contact between the outer wall 62 and the outer cover 53.

[0040] Furthermore, in this embodiment, the outer cover 53 has an upper plate 53b and a lower plate 53c. The upper plate 53b blocks the base opening 52a at a position higher than the lower plate 53c. The lower plate 53c supports the sealing member 61. In this embodiment, the end of the outer edge of the lower plate 53c is clamped by the sealing member 61. By clamping the end of the outer edge of the lower plate 53c by the sealing member 61, the sealing member 61 is installed on the lower plate 53c. By blocking the base opening 52a with the upper plate 53b, water intrusion into the receiving space 25 is suppressed, and by installing the sealing member 61 on the lower plate 53c, the sealing member 61 blocks the space between the lower plate 53c and the opposing portion 60, preventing water from intruding into the receiving space 25.

[0041] Figure 5 The image shows a perspective view of the perimeter of the base 52 of the straddle-type vehicle 1, viewed from an obliquely upward angle. Furthermore, Figure 6 The image shows a magnified view. Figure 5 A side view of a portion of the base 52 and the outer cover 53 in the straddle vehicle 1. Figure 6 This is a diagram showing the base 52 and outer cover 53 of the straddle-type vehicle 1 viewed from a direction orthogonal to the vertical and to the front-rear direction. Figure 6 In the illustration, the shape of the outer cover 53 is shown using a single-dot dashed line. Figure 5 As shown, the opposing portion 60 and the sealing member 61 are arranged to surround the base opening. Therefore, the opposing portion 60 and the sealing member 61 have portions 60a and 61a extending in the vehicle width direction and portions 60b and 61b extending in the front-rear direction. Among the opposing portions 60 and the sealing member 61, portions 60a and 61a extending in the vehicle width direction have front portions 60c and 61c extending in the vehicle width direction and rear portions 60d and 61d extending in the vehicle width direction. Figure 5 As shown, the sealing member 61, which is installed on the outer cover 53, is placed on the opposing part 60.

[0042] In the opposing section 60, the front portion 60c of the portion 60a extending in the vehicle width direction extends approximately straight along the vehicle width direction. The rear portion 60d of the portion 60a extending in the vehicle width direction becomes highest at its central portion in the vehicle width direction and slopes downwards from there towards the outer edge in the vehicle width direction. Furthermore, the portion 60b of the opposing section 60 extending in the vehicle's longitudinal direction slopes downwards from the front end towards the rear. That is, the opposing section 60 slopes relative to the horizontal direction. The lowest portion is formed in the middle of the portion of the opposing section 60 extending in the longitudinal direction. In this embodiment, the lowest portion is located rearwards from the central portion of the opposing section 60 in the longitudinal direction. The opposing section 60 slopes upwards as it moves rearwards from the lowest portion and connects with the portion extending in the vehicle width direction.

[0043] like Figure 5As shown, the opposing portion 60 is configured to be approximately linearly symmetrical with respect to the centerline L1 in the vehicle width direction. Furthermore, a guide portion 60h is provided on the inner side of the abutment portion 60g of the opposing portion 60 to restrict movement towards the inner side of the sealing member 61. The guide portion 60h is provided throughout the entire inner circumference of the abutment portion 60g, surrounding the inner side of the abutment portion 60g in the opposing portion 60, and has no cutouts. When the sealing member 61 is disposed on the opposing portion 60, the sealing member 61 is sandwiched between the outer wall 62 and the guide portion 60h.

[0044] In this embodiment, as described above, the housing 13 is mounted to the vehicle frame 4 at an angle toward the rear as it moves upward from the lower end. Therefore, the base 52 mounted on the housing 13 also tilts rearward as it moves upward from the lower end. Furthermore, in this embodiment, the opposing portion 60 formed on the base 52 is formed at an angle. Because the base 52 is angled, the angle of the opposing portion 60 formed on the base 52 can be easily formed.

[0045] As will be described later Figure 7 Thus, an outer wall 62 is provided radially outside the sealing member 61 surrounding the base opening 52a. The outer wall 62 has: a portion extending in the vehicle's longitudinal direction, a front portion extending in the vehicle width direction, and a rear portion extending in the vehicle width direction. The front portion extending in the vehicle width direction is located in front of portion 61c of the sealing member 61. The rear portion extending in the vehicle width direction is located behind portion 61d of the sealing member 61.

[0046] The outer wall 62 is formed with a portion cut off. Specifically, the cut-out portion 63 (drainage path) of the outer wall 62 is located between the portion extending in the vehicle's longitudinal direction and the rear portion extending in the vehicle width direction. At the cut-out portion 63 of the outer wall 62, the outer wall 62 is not covered by the sealing member 61. That is, by forming the cut-out portion 63 of the outer wall 62, a drainage path 64 is formed in the outer wall 62 from the inside to the outside relative to the outer wall 62. At the cut-out portion 63, the outer wall 62 is cut off in such a way that water moving outward in the vehicle width direction of the opposing portion 60 flows towards the outside of the vehicle.

[0047] In the outer wall 62, regarding the portion located to the side of the base opening 52a, the vertical height gradually decreases from the front to the rear, starting from the opposing portion 60. At the cutout portion 63, the vertical height of the outer wall 62 becomes minimal. In this embodiment, the outer wall 62 is formed at the same height as the opposing portion 60 at the cutout portion 63.

[0048] Figure 7 The middle shows along Figure 6 A sectional view along line VII-VII in the diagram. Figure 8 The middle shows along Figure 6A cross-sectional view of line VIII-VIII in the middle. Figure 9 The middle shows along Figure 6 A cross-sectional view of line IX-IX in the diagram. (See also...) Figure 7 As shown, in portions 60b and 61b of the opposing portion 60 and the sealing member 61, the outer wall 62 covers the outer side of portion 61b, and oppositely, as... Figure 8 As shown, the outer wall 62 is cut off at the cut portion 63, thus preventing water from entering between the sealing member 61 and the outer wall 62 from being blocked by the outer wall 62. Therefore, water entering between the sealing member 61 and the outer wall 62 flows out of the vehicle. In other words, at the cut portion 63, at least in the width direction of the base 52 and the outer cover 53, a gap is formed. Furthermore, with the outer cover 53 removed, at the cut portion 63, a portion 61b of the sealing member 61 is not covered by the outer wall 62, and the entire vertical direction of portion 61b is exposed to the outside of the vehicle. Therefore, with the outer cover 53 removed, the sealing member 61 includes: a covered portion 61e, the radially outer portion of the sealing member 61 surrounding the base opening 52a being covered by the outer wall 62; and an exposed portion 61f, the radially outer portion of which is exposed. With the outer cover 53 removed, at least the exposed portion 61f of the sealing member 61 is disposed at the lowest position in the vertical direction of the opposing portion 60.

[0049] The cutout portion 63 of the outer wall 62 is formed at the lowest position of the opposing portion 60 and the sealing member 61. That is, the portions 60b and 61b of the opposing portion 60 and the sealing member 61 slope downwards as they face rearwards, and the cutout portion 63 of the outer wall 62 is formed at a position corresponding to the furthest portion in the front-rear direction of the portions 60b and 61b of the opposing portion 60 and the sealing member 61. Therefore, at the lowest position of the opposing portion 60, the outer wall 62 exposes the exposed portion 61f of the sealing member 61 to the outside of the vehicle throughout the entire vertical direction.

[0050] In this embodiment, the contact portion 60g in the opposing portion 60 is formed from the front end in the front-rear direction to the cut portion 63 by a smooth plane or curved surface that slopes downward. In other words, a shielding portion that shields water from moving in the front-rear direction into the space surrounded by the sealing member 61, the opposing portion 60, and the outer wall 62 is not formed. Therefore, the opposing portion 60 is configured to guide water that has invaded between the sealing member 61 and the outer wall 62 in the front-rear direction.

[0051] As described above, in this embodiment, the straddle-type vehicle 1 includes a side support 20 that allows the vehicle to stand upright when tilted to one side in the vehicle width direction. Figure 1When the straddle-mounted vehicle 1 is upright by the side brace 20, the side brace 20 touches the ground on the side where it is located, thereby causing the straddle-mounted vehicle 1 to tilt towards the side where the side brace 20 is located in the vehicle width direction. In this embodiment, the exposed portions 61f of the sealing member 61 are provided on both sides in the vehicle width direction, and the sealing member 61 has two exposed portions 61f. The exposed portions 61f have a side brace-side exposed portion on the side where the side brace 20 is located, and an opposite side exposed portion on the side where the side brace 20 is not located. Since the exposed portions 61f are provided at two locations on both sides in the vehicle width direction, by allowing water to drain from the side brace-side exposed portion and the opposite side exposed portion, water accumulated inside the space between the sealing member 61 and the outer wall 62 can be drained more efficiently. As a result, water intrusion into the receiving space 25 can be more reliably suppressed.

[0052] When the straddle bracket 20 is used to support the straddle vehicle 1, and the straddle vehicle 1 is tilted, if the positions of the exposed portions on the side of the side bracket and the opposite side of the exposed portions on both sides in the vehicle width direction are compared, the straddle vehicle 1 tilts towards the side bracket 20, and the exposed portion on the side bracket is positioned at a lower position in the vertical direction compared to the exposed portion on the opposite side. That is, when the straddle vehicle 1 is supported by the side bracket 20 and is tilted, the lowest position of the opposing portion 60 is located on the side (one side) that the straddle vehicle 1 tilts when it is supported by the side bracket 20, relative to the base opening 52a in the vehicle width direction.

[0053] like Figure 5 As shown, the sealing member 61 is formed as an elongated strip extending longer than the outer periphery of the base opening 52a. The elongated sealing member 61 is disposed radially inside the outer wall 62 along the base opening 52a. The sealing members 61 partially overlap radially in the base opening 52a. In the sealing member 61, the portion that overlaps radially is the repeating portion 61g.

[0054] In this embodiment, the repeating portion 61g of the sealing member 61 is positioned relative to the base opening 52a in the vehicle width direction on the side where the straddle vehicle 1 is tilted when it is upright using the side support 20. Therefore, in the state where the straddle vehicle 1 is upright using the side support 20, the repeating portion 61g of the sealing member 61 is positioned on the side where the side support 20 is present and the straddle vehicle 1 is tilted. Thus, in the sealing member 61, the repeating portion 61g is located lower in the vertical direction compared to the side without the repeating portion 61g.

[0055] Furthermore, in this embodiment, as described above, the sealing member 61 is formed in an elongated shape, thus having two ends in the longitudinal direction. Also, as described above, in the portions of the opposing portion 60 and the sealing member 61 extending along the longitudinal direction of the straddle vehicle 1, the sealing member 61 slopes downwards in the vertical direction as it moves from the front to the rear in the longitudinal direction. The sealing member 61 has: one end (one end in the longitudinal direction) 61h, located at the front, from which the sealing member 61 extends rearward; and another end (another end in the longitudinal direction) 61i, located at the rear, from which the sealing member 61 extends forward. The other end 61i is the end opposite to the first end 61h in the sealing member 61. The portion 61n extending rearward from the first end 61h of the sealing member 61 and the portion 61p extending forward from the other end 61i of the sealing member 61 radially overlap in the repeating portion 61g. The first end 61h of the sealing member 61 is positioned radially inward than the other end 61i of the sealing member 61. The other end 61i of the sealing member 61 is located rearward in the front-rear direction than the first end 61h of the sealing member 61. Therefore, the other end 61i of the sealing member 61 is located lower in the vertical direction than the first end 61h of the sealing member 61. That is, the radially outer end 61i of the two ends 61h and 61i is located lower than the radially inner end 61h of the two ends 61h and 61i. Figure 6 As shown, in the repeating part 61g, the portion 61n extending from one end 61h of the sealing member 61 toward the rear of the vehicle and the portion 61p extending from the other end 61i of the sealing member 61 toward the front of the vehicle are arranged to overlap radially.

[0056] One end 61h and the other end 61i of the sealing member 61 are arranged to overlap radially, thus the volume of the sealing member 61 itself increases in the portion where the two ends overlap radially. Therefore, a large space is required to accommodate the sealing member 61 in the portion where the two ends overlap radially. In this embodiment, as... Figure 5 As shown, in the portion where one end 61h and the other end 61i of the sealing member 61 overlap radially, the radial width of the space 60k in the opposing portion 60 for arranging the sealing member 61 is ensured to be large. In the portion where one end 61h and the other end 61i of the sealing member 61 overlap radially, the radial width of the space 60k in the opposing portion 60 is ensured to be larger than the radial width of other spaces in the opposing portion 60, thus the sealing member 61 is reliably held by the opposing portion 60.

[0057] Furthermore, in this embodiment, the connection between the housing 13 and the vehicle frame 4 is covered from above by the base 52. Figure 10The figure shows a perspective view of the periphery of the connection portion 65 between the vehicle frame 4 and the housing 13 with the base 52 removed from the housing 13. Figure 11 The figure shows a cross-sectional perspective view of the internal structure of the housing 13.

[0058] In this embodiment, the housing 13 includes: a body 66 defining a battery receiving space 25; and a flange 67 projecting radially outward from the body 66 around the housing opening 21. The body 66 refers to the portion of the housing 13 formed by the combination of the peripheral wall 29 defining the receiving space 25 for the battery 14 and the inner bottom wall 28. The flange 67 is a plate-like portion disposed on the upper side of the peripheral wall 29. The flange 67 is positioned on the upper side of the peripheral wall 29 such that it projects outward from the peripheral wall 29 around the housing opening 21.

[0059] like Figure 4 and 10 As shown, a mounting portion 68 is provided near the front-rear end of the flange 67 in the housing 13. Furthermore, a hole 69 is provided in the mounting portion 68.

[0060] A support bracket 70 is provided on the vehicle frame 4 at a position opposite to the mounting part 68. A plate member 72 extending inward in the vehicle width direction from the tube 73 constituting the vehicle frame 4 is provided on the vehicle frame 4, and the support bracket 70 is mounted on the plate member 72. The support bracket 70 is constructed by bending the plate-shaped member, and a protrusion 71 protruding upward is provided on the upper surface of the support bracket 70.

[0061] When the housing 13 is mounted on the vehicle frame 4, a protrusion 71 provided on the support bracket 70 mounted on the vehicle frame 4 inserts into the hole 69 of the flange 67 of the housing 13 from below. If the protrusion 71 inserts into the hole 69, a bushing 74 is installed on the protrusion 71. Thus, the housing 13 is connected to the vehicle frame 4.

[0062] If the housing 13 is connected to the vehicle frame 4, a base 52 is installed on top of the housing 13. Figure 4 As shown, the base 52, located at the front side in the longitudinal direction of the straddle vehicle 1, includes an eave 75 that projects downward and covers the protrusion 71 and the mounting portion 68 from above. In this embodiment, the base 52 includes: a base body 52b that defines a portion of the receiving space 25 above the housing 13; and an eave 75 having a protrusion 75a projecting downward from the base body 52b. In the eave 75, the lower end 75b of the protrusion 75a is configured to be located below the upper surface of the mounting portion 68. In this embodiment, the protrusion 75a of the eave 75 extends along the vehicle width direction in a form that extends throughout the entire vehicle width direction of the base 52. Therefore, the protrusion 75a is configured to cover the gap between the base 52 and the housing 13 throughout the entire vehicle width direction.

[0063] Furthermore, in this embodiment, a drain hole is provided on the bottom wall 56 of the housing 13. As described above, in this embodiment, the bottom wall 56 includes an inner bottom wall 28, an outer bottom wall 48, and a peripheral wall 30 connecting the outer bottom wall 48 and the inner bottom wall 28. The bottom wall 56 has a bottom wall drain hole 76. Because the bottom wall drain hole 76 is formed in the bottom wall 56, water that has entered the receiving space 25 can be drained from the receiving space 25.

[0064] In this embodiment, an inner bottom wall drainage hole 77 is formed on the inner bottom wall 28 facing the receiving space 25, penetrating the inner bottom wall 28. In this embodiment, inner bottom wall drainage holes 77 are formed in the spaces for accommodating the two batteries 14a and 14b, respectively. Furthermore, a cover drain hole 78 is formed on the cover 36, which is composed of the outer bottom wall 48 and the peripheral wall 30, penetrating the cover 36. In this embodiment, a cover drain hole 78 is formed on the rear part of the peripheral wall 30 of the cover 36. The cover drain hole 78 is formed on the peripheral wall 30 near the lower end 30a. Since an inner bottom wall drainage hole 77 is formed on the inner bottom wall 28, when water enters the receiving space 25 of the housing 13, the intruding water is directed into the lower space 33. Furthermore, since a cover drain hole 78 is formed on the cover 36, penetrating the peripheral wall 30, when water enters the lower space 33, the intruding water is discharged to the outside.

[0065] The inner bottom wall drainage holes 77 are formed at least in the lower position when the vehicle body is tilted using the side support 20, according to each space used to accommodate the battery 14. In addition, in this embodiment, the inner bottom wall 28 is provided with inner bottom wall drainage holes 86, which do not guide the intruding water into the lower space 33 but discharge it directly to the outside when water intrudes into the accommodating space 25.

[0066] In this embodiment, a lower partition wall 79 is provided inside the lower space 33. This lower partition wall 79 protrudes upward from the outer bottom wall 48 and extends along the vehicle width direction and the entire width direction of the cover 36. The lower partition wall 79 is configured such that there is only a slight gap between its upper side and the inner bottom wall 28, while occupying almost the entire lower space 33. Furthermore, an upper partition wall 80 is provided inside the lower space 33. This upper partition wall 80 protrudes downward from the inner bottom wall 28 and extends along the vehicle width direction and the entire width direction of the cover 36. The upper partition wall 80 has a relatively large gap with the outer bottom wall 48 in the vertical direction, and its vertical length is shorter than that of the lower partition wall 79. In this embodiment, the lower partition wall 79 is positioned further forward than the upper partition wall 80 in the front-rear direction.

[0067] A partition wall drainage hole 81 is formed in the lower partition wall 79 in a manner that extends through the lower partition wall 79 in the longitudinal direction of the vehicle. The partition wall drainage hole 81 is formed in the lower partition wall 79 at a position close to the outer bottom wall 48. That is, the partition wall drainage hole 81 is formed at a position close to the lower end of the lower partition wall 79. In this embodiment, the partition wall drainage hole 81 is also included in the bottom wall drainage hole 76.

[0068] Furthermore, in this embodiment, a peripheral wall drainage hole 82 penetrating the peripheral wall 29 is provided on the upper part of the peripheral wall 29 of the housing 13. Therefore, when water enters the interior of the receiving space 25 from between the base 52 and the housing 13, the intruding water spreads along the peripheral wall 29 due to gravity and moves towards the peripheral wall drainage hole 82, passing through the peripheral wall drainage hole 82 and being discharged to the outside of the receiving space 25 of the housing 13. In this embodiment, the peripheral wall drainage hole 82 is formed at both the front side in the front-rear direction and the rear side in the front-rear direction of the housing 13.

[0069] Furthermore, in this embodiment, the peripheral wall 29 has a front peripheral wall, namely the front peripheral wall 29b, and a rear peripheral wall, namely the rear peripheral wall 29c. The front peripheral wall 29b includes: a front peripheral wall main body 29d, which extends upward from the inner bottom wall 28; a front portion 29e, which bends forward in the forward-rear direction from the front peripheral wall main body 29d and extends upward as it bends forward; a curved portion 29f of the front peripheral wall 29b; and a partition plate 29g, which extends upward from the curved portion 29f. Therefore, even if water intrudes from the joint between the base 52 and the housing 13, the partition plate 29g can prevent water from intruding into the battery housing position in the housing space 25. Water is temporarily stored inside the front space 88 surrounded by the base 52, the front portion 29e, and the partition plate 29g. Water that intrudes into the front space 88 of the housing space 25 moves downward along the wall of the front portion 29e and is discharged to the outside through the peripheral wall drainage hole 82 of the front peripheral wall 29b. Thus, even if water intrudes into the interior of the front space 88 from the joint between the base 52 and the housing 13, it is possible to prevent the intruding water from entering the interior of the battery housing position in the housing space 25.

[0070] Similarly, the rear peripheral wall 29c includes: a rear peripheral wall main body 29h extending upward from the inner bottom wall 28; a rear portion 29i bending backward from the rear peripheral wall main body 29h in a rearward direction and extending upward as it bends backward; a curved portion 29k of the curved rear peripheral wall 29c; and a partition plate 29m extending upward from the curved portion 29k. Therefore, even if water intrudes from the joint between the base 52 and the housing 13, the partition plate 29m can suppress water intrusion into the battery housing position in the housing space 25, and the water is temporarily stored inside the rear space 89 surrounded by the base 52, the rear portion 29i, and the partition plate 29m. Water that intrudes into the rear space 89 of the housing space 25 moves downward along the wall surface of the rear portion 29i and is discharged to the outside through the peripheral wall drainage holes 82 of the rear peripheral wall 29c. Therefore, even if water enters the interior of the rear space 89 from the seam between the base 52 and the housing 13, it can prevent the water from entering the interior of the battery housing in the housing space 25.

[0071] Furthermore, in this embodiment, an inner cover 42 is provided on the housing 13 in the form of blocking the housing opening 21 of the housing 13. Therefore, even if water enters through the base opening 52a, the inner cover 42 can prevent water from entering the battery housing position in the housing space 25. In addition, in this embodiment, a base drain hole 90 is provided in the base 52, penetrating the base 52. With the base drain hole 90 provided in the base 52, even if water enters the inside of the base opening 52a, the water can be discharged to the outside through the base drain hole 90. Therefore, water can be more reliably prevented from entering the battery housing position.

[0072] According to this embodiment, the sealing member 61 faces the base opening 52a, is mounted on the outer cover 53, and protrudes toward the opposing portion 60 of the base 52. The outer wall 62 is located outside the sealing member 61, between the outer cover 53 and the opposing portion 60 in the vertical direction. Therefore, both the sealing member 61 and the outer wall 62 can prevent water from entering the receiving space 25. Even if water exceeds the outer wall 62 and enters its inner side, the sealing member 61 can still prevent water from entering the receiving space 25. Furthermore, at the lowest position of the opposing portion 60, the outer wall 62 exposes either the sealing member 61 or the opposing portion 60 toward the outside of the vehicle. In other words, in the opposing portion 60, the opposing surface 60e facing the outer cover 53 is inclined relative to the horizontal direction. The opposing surface 60e, in the side portion of the base opening 52a, is inclined downwards as it faces rearwards. Furthermore, a vertical gap is formed between the upper end 62c of the outer wall 62 and the opposing surface 60e. Thus, the water that intrudes between the outer wall 62 and the sealing member 61 flows outward from the outer side of the sealing member 61 toward the space 85 between the upper end 62c of the outer wall 62 and the facing surface 60e. Figure 7 and 9The water in the space 85 between the upper end of the outer wall 62 and the opposing surface 60e on the outside of the sealing member 61 moves downward toward the opposing portion 60 due to gravity. Rainwater advances toward the exposed portion 61f, which is located at the lowest position in the opposing portion 60. When the water reaches the exposed portion 61f, since there is no or no outer wall 62 in the exposed portion 61f, the water that has entered between the outer wall 62 and the sealing member 61 is discharged outward from the opposing portion 60. Therefore, water intrusion into the opposing portion 60 can be prevented, and even if water were to intrude into the opposing portion 60 through the outer wall 62, it is discharged outward, suppressing water accumulation in the opposing portion 60. Thus, water intrusion into the housing opening 21 through the base opening 52a can be suppressed. At this time, the water inside the space 85 flows from the inside of the outer wall 62 toward the outside in the cutout portion 63. Therefore, the cut portion 63 of the outer wall 62 drains water from the interior of the space 85 to the outside, functioning as a drainage path from the inside to the outside relative to the outer wall.

[0073] Furthermore, according to this embodiment, the sealing member 61 is formed in an elongated shape. The sealing member 61 extends longer than the outer periphery of the base opening 52a. In this way, the sealing member 61 partially overlaps the base opening 52a in the radial direction. Compared with the case where the sealing member 61 is formed around the outer periphery and connected at both ends, it is possible to prevent water from entering the receiving space 25 through the base opening 52a from the seam of the sealing member 61.

[0074] Furthermore, according to this embodiment, the opposing portion 60 is inclined downwards and outwards from the front in the front-to-back direction. The portion 61n extending rearwards from one end 61h in the longitudinal direction of the sealing member 61 and the portion 61p extending forwards from the other end 61i in the longitudinal direction of the sealing member 61 overlap radially. The other end 61i, located radially outwards, is positioned lower than the end 61h located radially inwards. Therefore, the gap between the portion 61n extending rearwards from one end 61h in the longitudinal direction of the sealing member 61 and the portion 61p extending forwards from the other end 61i in the longitudinal direction of the sealing member 61 is rearwards and downwards. Therefore, assuming that in the repeating portion 61g of the sealing member 61, even if water intrudes between the portion 61n extending rearward from one end 61h in the longitudinal direction of the sealing member 61 and the portion 61p extending forward from the other end 61i in the longitudinal direction of the sealing member 61, the water will move rearward and downward due to gravity, and will be discharged to the outside from the outer cover 53 and the base 52 through the gap between the portion 61n extending rearward from one end 61h in the longitudinal direction of the sealing member 61 and the portion 61p extending forward from the other end 61i in the longitudinal direction of the sealing member 61. Thus, in the repeating portion 61g of the sealing member 61, water exceeding the outer wall 62 can be prevented from intruding into the interior of the receiving space 25. Furthermore, since the gap between the portion 61n extending rearward from one end 61h in the longitudinal direction of the sealing member 61 and the portion 61p extending forward from the other end 61i in the longitudinal direction of the sealing member 61 faces rearward and downward, water can be prevented from intruding into the receiving space 25 through the gap during operation.

[0075] The repeating portion 61g is positioned above the lowest point of the opposing portion 60. In other words, the repeating portion 61g is positioned differently from the portion of the outer wall 62 that exposes the sealing member 61 or the opposing portion 60. This prevents rainwater from reaching the repeating portion 61g through the portion lacking or without the outer wall 62.

[0076] Furthermore, according to this embodiment, when the straddle-type vehicle 1 is upright using the side brace 20, the lowest position of the exposed opposing portion 60 of the sealing member 61 is located on the side brace 20 side in the vehicle width direction relative to the base opening 52a. Therefore, when the straddle-type vehicle 1 is upright using the side brace 20, water that has entered between the sealing member 61 and the outer wall 62 can be discharged to the outside of the vehicle through the exposed portion 61k on the side brace 20 side. Thus, water drainage performance can be further improved.

[0077] Furthermore, according to this embodiment, when the straddle vehicle 1 is upright using the side brace 20, the repeating portion 61g of the sealing member 61 is positioned relative to the base opening 52a on the side of the straddle vehicle 1 that is lower due to tilting in the vehicle width direction. Therefore, when water enters between the sealing member 61 and the outer wall 62, when the straddle vehicle 1 is parked, the water is discharged to the outside through the gap between the portion 61n extending rearward from one end 61h in the longitudinal direction and the portion 61p extending forward from the other end 61i in the longitudinal direction of the repeating portion 61g. Therefore, drainage performance can be improved.

[0078] Furthermore, according to this embodiment, an inner cover 42 capable of opening and closing the housing opening 21 is provided, thus more reliably preventing water from entering the containing space 25.

[0079] Furthermore, according to this embodiment, a peripheral wall drainage hole 82 is provided on the peripheral wall 29, so it is assumed that even if water enters the receiving space 25, the water can be drained to the outside. Therefore, it is possible to prevent water from entering the electrical connection between the output terminal 32 of the battery 14 and the connector 31 of the housing 13.

[0080] Furthermore, according to this embodiment, the base 52 includes an eave 75 that covers the flange 67 of the housing 13 from above, thus the eave 75 can block the seam between the base 52 and the housing 13. Therefore, it is possible to prevent water from the base 52 from entering the receiving space 25, and it is also possible to prevent water from entering the receiving space 25 through the seam between the base 52 and the housing 13. As a result, the waterproofness of the housing 13 can be further improved.

[0081] Furthermore, according to this embodiment, the bottom wall 56 has a bottom wall drain hole 76 for draining water that has entered the receiving space 25 from the receiving space 25. Therefore, even if water enters the receiving space 25, the water can be discharged to the outside of the housing 13 through the bottom wall drain hole 76.

[0082] Furthermore, according to this embodiment, a lower partition wall 79 protruding upward from the outer bottom wall 48 and an upper partition wall 80 protruding downward from the inner bottom wall 28 are provided inside the lower space 33. Therefore, the lower partition wall 79 and the upper partition wall 80 can be used to suppress water intrusion into the front of the lower space 33. In this embodiment, a connector 31 is provided in the housing 13, and the lower space 33 is provided adjacent to the connector 31. Therefore, a wiring harness extending from the connector 31 is arranged inside the lower space 33. In this embodiment, the lower partition wall 79 and the upper partition wall 80 are arranged behind the wiring harness, thus suppressing water intrusion into the front of the lower space 33 and preventing water from contacting the wiring harness.

[0083] Furthermore, a partition wall drain hole 81 is provided near the outer bottom wall 48 of the lower partition wall 79. Since the housing 13 and the cover 36 slope downwards and backwards, when water intrudes into the lower space 33, it moves downwards towards the outer bottom wall 48 due to gravity. Upon reaching the outer bottom wall 48, it moves backwards along the sloped outer bottom wall 48. The partition wall drain hole 81 at the lower part of the lower partition wall 79 allows water flowing along the outer bottom wall 48 to move further backwards through the partition wall drain hole 81 and be discharged to the outside of the cover 36 through the cover drain hole 78. Therefore, when water intrudes into the lower space 33, it can be discharged from the lower space 33 through the partition wall drain hole 81.

[0084] Furthermore, in this embodiment, the connector 31 is mounted on the inner bottom wall 28, so the wiring from the connector 31 is disposed on the lower surface of the inner bottom wall 28, above the lower space 33. Moreover, when water enters the lower space 33, the intruding water flows rearward along the outer bottom wall 48. Therefore, even assuming water enters the lower space 33, the water flows within the space below the wiring, preventing water from flowing towards the wiring and simultaneously discharging the intruding water to the outside of the lower space 33. Thus, a housing 13 can be used to protect the wiring.

[0085] Furthermore, according to this embodiment, the battery 14 that supplies power to the electric motor M that drives the drive wheels of the vehicle is housed in the accommodating space 25, thus suppressing contact between water and the battery 14, and suppressing contact between the output terminal 32 of the battery 14 and water.

[0086] In this embodiment, it is assumed that the casing is used for cleaning the body of the passenger vehicle 1 with high-pressure water. Even when high-pressure water is used for cleaning the body, the aforementioned water-proof structure prevents water from entering the battery housing. Furthermore, even if water slightly enters the battery housing due to high-pressure water, it can be discharged to the outside of the casing 13 through the bottom wall drain hole 76. This prevents rainwater from accumulating in the casing 13.

[0087] Furthermore, in the above embodiment, the structure in which the sealing member 61 and the outer wall 62 are disposed on the base 52 has been described, but it is not limited to the above embodiment. The sealing member 61 and the outer wall 62 may also be disposed on the outer cover 53. Alternatively, the sealing member may be disposed on either the base or the outer cover, and the outer wall may be disposed on either the base or the outer cover. As long as it is formed such that it is disposed on either the outer cover 53 or the base 52, blocking the space between the outer cover 53 and the base 52 and preventing water from entering the base opening 52a, the sealing member 61 and the outer wall 62 may be disposed on either the outer cover 53 or the base 52.

[0088] Furthermore, while the above embodiments describe an electric straddle-type vehicle, the description is not limited to these embodiments. The vehicle can also be a hybrid vehicle driven by an electric motor and an internal combustion engine. Additionally, the vehicle can be driven solely by an internal combustion engine. As long as it has an outer cover, a housing, and a base, and prevents water intrusion from between the outer cover and the base when the outer cover is closed, the vehicle can be of any form.

[0089] Furthermore, in the above embodiment, the protruding member installed on the outer cover 53, facing the base opening 52a and protruding towards the base 52, is described as the form of the sealing member 61, but it is not limited to the above embodiment. The protruding member can be any structure located between the outer cover 53 and the opposing portion 60 in the vertical direction, blocking a portion of the space between the outer cover 53 and the opposing portion 60. As long as it blocks a portion of the space between the outer cover 53 and the opposing portion 60, it can be a structure that blocks the entire space between the outer cover 53 and the opposing portion 60, or it can be a structure that partially blocks the space between the outer cover 53 and the opposing portion 60. Furthermore, the protruding member may not be deformable. The protruding member can be an inner wall formed on the radially inner side of the outer wall 62. The protruding member can be a structure provided on the outer cover, but it can also be a structure provided on the opposing portion side.

[0090] Furthermore, in the above embodiment, the opposing portion 60 is a structure that tilts downward as it moves from the front to the rear, but it is not limited to this. For example, the opposing portion 60 may also be a structure that tilts downward as it moves from the rear to the front. Alternatively, the opposing portion 60 may be a structure that tilts downward as it moves from the inner part in the vehicle width direction toward the outer part in the vehicle width direction.

[0091] Furthermore, in the above embodiment, the configuration where the exposed portion 61f exposes the radially outer portion of the sealing member 61 at the lowest position of the opposing portion 60 when the outer cover 53 is removed is described, but this is not limited to the above embodiment. The exposed portion 61f, appearing when the outer cover 53 is removed, may also have the opposing portion 60, which the sealing member 61 abuts against, exposed outwards instead of the sealing member 61. As long as water intruding into the space surrounded by the sealing member 61, the opposing portion 60, and the outer wall 62 is drained through the drainage channel formed by the cut portion 63 of the outer wall 62, the opposing portion 60 and the sealing member 61 may not be exposed when the outer cover 53 is installed. Furthermore, in the above embodiment, the configuration where the exposed portion 61f is provided on both the left and right sides in the vehicle width direction is described, but this is not limited to the above embodiment. The exposed portion 61f may be provided only on either the left or right side in the vehicle width direction. In this case, only the side brace exposed portion may be provided, which becomes the lowest position in the opposing portions 60 when the straddle 1 is tilted due to the use of the side brace 20 to make the straddle 1 stand upright. Alternatively, multiple exposed portions 61f may be provided on one side of the straddle 1 in the vehicle width direction.

[0092] Furthermore, in the above embodiment, the form in which the radially outer portion of the sealing member 61 is exposed in the exposed portion 61f at the lowest position of the opposing portion 60 is described, but it is not limited to the above embodiment. Considering drainage, when the straddle-mounted vehicle 1 is upright using the side brace 20 and thus tilted, it is preferable to expose the opposing portion 60 or the sealing member 61 at the lowest position in the opposing portion 60. However, the exposed portion 61f can be formed in a region located somewhat lower in the opposing portion 60, or it can be formed at a position somewhat higher than the lowest position to prevent water from entering the base opening 52a. Similarly, the cutout portion 63 can also be formed in a region located somewhat lower in the opposing portion 60, or it can be formed at a position somewhat higher than the lowest position to prevent water from entering the base opening 52a. In addition, when the straddle-mounted vehicle 1 is upright using the center support, the vehicle body does not tilt and maintains an upright state, therefore there are multiple positions in the opposing portion 60 that are at the lowest position. In this case, the exposed portion 61f can be formed in each region where the opposing portion 60 is at its lowest position. Furthermore, if the opposing portion 60 has a structure that extends downwards from the front end toward the rear, the exposed portion 61f is preferably formed in the opposing portion 60 below the center portion in the front-rear direction.

[0093] Furthermore, in the above embodiment, the opposing surface 60e of the opposing portion 60 that faces the outer cover 53 is as follows: Figure 7 , 8The structure of the horizontal plane along the vehicle width direction shown in Figure 9 has been described, but it is not limited to the above embodiment. The opposing surface 60e may not be a horizontal plane along the vehicle width direction, but may be inclined. As long as the opposing surface 60e is configured to slope downwards from the radially inner side to the outer side, water that has entered the space surrounded by the opposing surface 60e, the sealing member 61, and the outer wall 62 can move radially outwards along the inclination of the opposing surface 60e, and the movement of the intruding water to the radially inner side is suppressed. Therefore, in order to suppress the intrusion of water into the interior of the base opening 52a, it is preferable that the opposing surface 60e slopes downwards from the radially inner side to the outer side.

[0094] Furthermore, in the above embodiment, the configuration of the sealing member 61 surrounding the base opening 52a and the exposed portion 61f being provided at a position facing the base opening 52a has been described, but this is not limited to the above embodiment. The exposed portion 61f may also be formed at a position away from the base opening 52a in the front-rear direction. Alternatively, the sealing member 61 may be configured to pass through a position away from the base opening 52a in the front-rear direction, while the radially outer portion of the sealing member 61 surrounding the base opening 52a is exposed at a position away from the base opening 52a in the front-rear direction, and the exposed portion 61f is formed at a position away from the base opening 52a in the front-rear direction. The exposed portion 61f is formed away from the base opening 52a, thereby preventing water from entering the inside of the base opening 52a through the exposed portion 61f. Similarly, the cutout portion 63 of the outer wall 62 may also be configured rearward than the rear end of the base opening 52a or the housing opening 21. By forming the outer wall 62 in this way, it is possible to prevent water from entering the inside of the base opening 52a through the cutout portion 63. Furthermore, as described above, the cut portion 63 can be formed at a position that is farther away from the repeating portion 61g of the sealing member 61 in the front-back direction, and is particularly preferably farther away rearward as in this embodiment.

[0095] Furthermore, in the above embodiment, the shape of the base opening 52a being formed in front of the seat 12 has been described, but it is not limited to the above embodiment. The base opening 52a can be located in other positions. For example, the base opening 52a can be located behind the seat 12, or the base opening 52a can be formed directly below the seat 12.

[0096] Furthermore, in the above embodiment, the shape of the portion exposing the radially outer side of the sealing member 61 at the lowest position of the opposing portion 60 has been described, but it is not limited to the above embodiment. The radially outer side of the sealing member 61 does not necessarily have to be at the lowest position in the opposing portion 60. It is fine as long as it is a position lower than the upper end 60f of the opposing portion 60. As long as the radially outer side of the sealing member 61 is exposed at a position lower than the upper end 60f, water that has infiltrated the area from the upper end 60f to the exposed portion 61f of the sealing member 61 is discharged through the exposed portion 61f. Therefore, in the area from the upper end 60f to the exposed portion 61f of the sealing member 61, water that has infiltrated the inner side of the outer wall 62 can be discharged, thereby improving drainage performance.

[0097] Furthermore, in the above embodiment, a waterproof structure for preventing water from entering the interior of the battery housing's receiving space at the seam between the outer cover 53 and the base 52 has been described, but it is not limited to the above embodiment. The same structure can also be applied to housings other than the battery housing. For example, in a storage box that houses gloves, helmets, etc., the structure of the above embodiment can also be applied at the seam between the outer cover and the opening in the housing.

[0098] Furthermore, in the above embodiment, the housing 13 and the base 52 were described as being independently constructed, but the housing 13 and the base 52 can also be integrally formed. For example, the housing 13 and the base 52 can be integrally formed. Furthermore, in the above embodiment, the configuration of having an opposing portion 60 around the base opening 52a in the base 52 was described, but this is not limited to the above embodiment. For example, the opposing portion 60 can also be formed around the housing opening 21 in the housing 13. Furthermore, in the above embodiment, the configuration of having an inner cover 42 installed at the upper end of the housing 13 to close the housing opening 21 was described, but this is not limited to the above embodiment. The inner cover 42 may not be provided at the upper end of the housing 13. As long as the waterproof structure between the outer cover 53 and the opposing portion 60 can sufficiently prevent water from entering the housing opening 21, the inner cover 42 may not be installed on the housing 13.

[0099] Furthermore, in the above embodiment, the outer wall 62 is provided on the base 52, and the portion of the base 52 that is further outward than the opposing portion 60 is described to form the outer wall 62, but this is not limited to the above embodiment. The outer wall 62 may not be provided on the base 52. Alternatively, the upper plate 53b of the outer cover 53 may extend outward, forming the outer wall 62 by covering the radially outer portion of the sealing member. In the case where the outer wall 62 is formed in the radially outwardly extending portion of the outer cover 53, Figure 12 The middle shows the equivalent Figure 6 A sectional view of the portion of line VIII-VIII.

[0100] exist Figure 12 In this configuration, the portion of the sealing member 61 that is not exposed 61f is covered by the outermost portion of the upper plate 53b of the outer cover 53 extending outward. The outermost portion of the upper plate 53b of the outer cover 53 functions as an outer wall covering the outermost portion of the sealing member 61. Furthermore, Figure 12 As shown, a drain passage 91 for draining water is formed between the upper plate 53b of the outer cover 53 and the opposing portion 60 of the base 52. Therefore, when water enters the space 85 surrounded by the opposing portion 60, the sealing member 61, and the outer cover 53, and moves on the opposing portion 60 to reach the position of the drain passage 91, the water inside the space 85 is discharged to the outside through the drain passage 91.

[0101] In addition, Figure 12 In the middle, the opposing surfaces 60e of the opposing section 60 slope downwards towards the radially outward direction. Therefore, water that has intruded into the space 85 surrounded by the opposing section 60, the sealing member 61, and the outer cover 53 flows radially outwards due to its own weight. Therefore, water that reaches the discharge passage 91 flows radially outwards due to its own weight and is discharged to the outside through the discharge passage 91.

[0102] exist Figure 12 In this configuration, a drain passage 91 is formed between the upper plate 53b of the outer cover 53 and the base 52. Therefore, even if water enters between the outer cover 53 and the sealing member 61, water that has entered the space 85 surrounded by the outer cover 53, the sealing member 61, and the opposing portion 60 is discharged to the outside through the drain passage 91. Thus, the upper plate 53b of the outer cover 53 can prevent water from entering the opposing portion 60, and even if water enters the opposing portion 60 through the upper plate 53b of the outer cover 53, the water can be discharged to the outside, suppressing water accumulation in the opposing portion 60. Consequently, water can be prevented from entering the housing opening 21 through the base opening 52a.

[0103] In addition, Figure 12 In this configuration, the opposing surfaces 60e of the opposing portions 60 are inclined downwards towards the radially outward direction, but the opposing surfaces 60e may not be inclined. Even if the opposing surfaces 60e are configured horizontally along the vehicle width direction, water that has intruded between the outer cover 53 and the sealing member 61 can be discharged to the outside through the discharge passage 91 between the upper plate 53b and the base 52. Therefore, as long as the water that has intruded between the outer cover 53 and the sealing member 61 can be discharged to the outside, the opposing surfaces 60e may not be inclined and may be configured horizontally along the vehicle width direction.

[0104] Furthermore, while the form in which the outer wall 62 is formed on the base 52 has been described in the above embodiment, it is not limited to the above embodiment. The outer wall 62 may also be provided on the outer cover 53. Figure 13The diagram shows a cross-sectional view of the outer cover 53, which has an outer wall, the opposing portion 60, and the sealing member 61. Figure 13 It is equivalent to Figure 6 A sectional view of the portion of line VIII-VIII.

[0105] like Figure 13 As shown, an outer wall 62d is provided on the upper plate 53b of the outer cover 53. In this embodiment, the upper plate 53b is configured to cover the outer side of the opposing portion 60, and the outer wall 62d extends from the lower wall surface of the upper plate 53b toward the opposing portion 60. Regarding the portion where the drain passage 91a is not provided, the outer wall 62d of the outer cover 53 covers the radially outer side of the sealing member 61. Therefore, in the portion where the drain passage 91a is not provided, the outer wall 62d prevents water from intruding radially inward. Figure 13 A discharge passage 91a is formed between the outer wall 62d and the opposing portion 60 in the vertical direction. Since the discharge passage 91a is formed below the outer wall 62d, water that has entered the space 85 surrounded by the outer cover 53, the sealing member 61, and the opposing portion 60 is discharged to the outside through the discharge passage 91a. Therefore, the outer wall 62d can prevent water from entering the opposing portion 60, and even if water enters the space 85 surrounded by the outer cover 53, the sealing member 61, and the opposing portion 60 through the outer wall 62d, the water can be discharged to the outside of the vehicle, suppressing water accumulation in the space 85. Thus, water can be prevented from entering the housing opening 21 through the base opening 52a.

[0106] Furthermore, in the above embodiment, the configuration of the sealing member 61 mounted on the outer cover 53 and arranged on the opposing portion 60 when the outer cover 53 is closed has been described, but it is not limited to the above embodiment. The sealing member may also be mounted on the opposing portion 60. Figure 14 The diagram shows a cross-sectional view of the outer cover 53, the opposing portion 60, and the sealing member 61m, which are mounted on the opposing portion 60 and extend upward toward the outer cover 53. Figure 14 It is equivalent to Figure 6 A sectional view of the portion of line VIII-VIII.

[0107] like Figure 14 As shown, the sealing member 61m is mounted on the connecting member 92, which extends upward from the opposing portion 60 toward the outer cover 53, and the connecting member 92 is mounted on the opposing portion 60, while the sealing member 61m is mounted on the opposing portion 60. The sealing member 61m is provided on the opposing portion 60 of the base 52 and protrudes upward. At this time, as... Figure 14 As shown, the sealing member 61m can also be located outside the base opening 52a. In this case, the protruding member 61m is located around the base opening 52a in the form of a circle around the outside of the base opening 52a.

[0108] In addition, such as Figure 14 As shown, the sealing member 61m can also be configured to be installed on the opposing portion 60. In this embodiment, in the portion where the drain passage 91b is not provided, the upper plate 53b of the outer cover 53 covers the radially outer side of the sealing member 61m. Therefore, in the portion where the drain passage 91b is not provided, the upper plate 53b prevents water from intruding radially inward. Figure 14 In this structure, a discharge passage 91b is formed between the upper plate 53b of the outer cover 53 and the opposing portion 60. Because of this discharge passage 91b, water that has entered the space 85 surrounded by the outer cover 53, the sealing member 61, and the opposing portion 60 is discharged to the outside through the discharge passage 91b. Therefore, the upper plate 53b of the outer cover 53 can prevent water from entering the opposing portion 60, and even if water enters the space 85 through the upper plate 53b, it can be discharged to the outside, thus suppressing water accumulation in the space 85. Consequently, water can be prevented from entering the housing opening 21 through the base opening 52a. Figure 14 In this form, the upper plate 53b of the outer cover 53 functions as the outer wall.
