Description

Technical Field

[0001] This invention relates to luggage mounting structures.

[0002] This application claims priority based on Japanese Patent Application No. 2022-187559, filed on November 24, 2022, the contents of which are incorporated herein by reference. Background Technology

[0003] Previously, a structure was disclosed in which a luggage compartment is provided on the front side below the seat and a fuel tank is provided on the rear side below the seat, and the fuel tank flange at the front and the mounting part at the rear of the luggage compartment are fastened together to a cross frame between the left and right seat frames (for example, see Japanese Patent No. 5581674). Summary of the Invention

[0004] However, in the existing structure described above, the mounting position (fastening connection position) of the fuel tank side of the luggage compartment is restricted in the vertical direction to the same height as the cross frame between the left and right seat frames, and in the front-back direction, from the viewpoint of ensuring tank capacity, it is affected by the front position of the fuel tank due to the cross frame. Furthermore, the luggage compartment capacity may also be limited depending on the mounting position of the fuel tank side.

[0005] The objective of this invention is to ensure the capacity of the luggage compartment in a luggage compartment mounting structure of a vehicle having a luggage compartment and a fuel tank arranged in one direction, without suppressing the capacity of the fuel tank.

[0006] To achieve the above objectives, the luggage mounting structure of the present invention adopts the following structure.

[0007] (1) The first aspect of the present invention is a luggage compartment mounting structure for a vehicle, comprising: a fuel tank 15 supported on a vehicle body 1A; a luggage compartment 40 disposed in front of the fuel tank 15; and a fuel tank tray 30 disposed above the fuel tank 15, wherein the front part 31 of the fuel tank tray is mounted to at least one of the vehicle body 1A and the fuel tank 15 via a first mounting part 35, and the rear part 41 of the luggage compartment 40 is mounted to the fuel tank tray 30 via a second mounting part 46, the second mounting part 46 being located above and behind the first mounting part 35.

[0008] According to the above-described (1) scheme, the rear part of the fuel tank side in the luggage compartment located in front of the fuel tank is mounted on a fuel tank tray located above the fuel tank. Therefore, compared to a structure where the rear part of the luggage compartment is mounted on a cross frame or similar structure located between the fuel tank and the luggage compartment, the rear part of the luggage compartment can extend upwards towards the fuel tank side. Thus, the capacity of the fuel tank side of the luggage compartment can be further ensured without restricting the capacity of the fuel tank.

[0009] The rear of the trunk is mounted to the fuel tank tray at a second mounting point, different from the first mounting point for the fuel tank. Therefore, compared to a structure where the fuel tank and trunk share a mounting point, one of the fuel tank or trunk can be installed or removed without being affected by the installation status of the other. This simplifies the installation and removal of the fuel tank and trunk, improving vehicle maintainability. In particular, when the vehicle's power unit is located under the trunk, the maintainability of the power unit is also improved.

[0010] (2) In the above (1) scheme, the rear part 41 of the suitcase 40 may be mounted only on the fuel tank tray 30 via the second mounting part 46.

[0011] According to the above (2) scheme, compared with the structure that installs the rear of the luggage compartment in a structure other than the fuel tank tray (fuel tank, body, etc.), the position of the second mounting part can be set without depending on the position of other structures, which can improve the design freedom of the rear of the luggage compartment.

[0012] (3) In the above-mentioned (1) solution, the fuel tank 15 and the fuel tank tray 30 can also be installed together on the vehicle body 1A in the first mounting part 35.

[0013] According to the above scheme (3), in the first mounting part, the fuel tank tray and the fuel tank are mounted on the vehicle body by common fastening, etc., thus simplifying the mounting structure of the fuel tank tray and the fuel tank.

[0014] (4) In the above (1) scheme, the first mounting part 35 and the second mounting part 46 are respectively arranged as a pair on the left and right sides in the vehicle width direction, and the second mounting part 46 for mounting the luggage box 40 is arranged in a position that is closer to the inside of the vehicle width direction than the first mounting part 35 for mounting the fuel tank tray 30.

[0015] According to the above scheme (4), the pair of second mounting parts for installing the luggage compartment are positioned inside the vehicle width direction of the pair of first mounting parts 35 for installing the fuel tank tray. Therefore, the first mounting parts and the second mounting parts can be positioned close to each other in the front-rear direction without depending on the other party's position, which can improve the configuration freedom of the first mounting parts and the second mounting parts.

[0016] (5) In the above (4) scheme, the vehicle body 1A may also have a pair of left and right frame members 10e supporting the fuel tank 15 in the vehicle width direction, and a pair of first mounting parts 35 are disposed on the pair of frame members 10e.

[0017] According to the above scheme (5), a pair of first mounting parts are separately arranged on each pair of frame members. Therefore, the first mounting parts are located on the outside in the vehicle width direction and are easily accessible to the operator, which improves the workability of the first mounting parts. In addition, compared with the case where the first mounting parts are arranged on the cross frame between the pair of frame members, the design freedom of the cross frame and the frame can be increased.

[0018] (6) In the above (5) scheme, the fuel tank tray 30 may also be made of resin that is lighter per unit weight than the metal frame member 10e, and the fuel tank tray 30 has a lower extension 36 that extends downward from the tray body toward the frame member 10e and includes the structure of the first mounting portion 35 at the lower end.

[0019] According to the above (6) scheme, the lower extension constituting the first mounting part extends from the fuel tank tray, which is lighter than the frame member, toward the frame member. This achieves weight reduction compared to the case where the fuel tank tray is mounted by extending a metal bracket or the like from the frame member.

[0020] (7) In the above (6) scheme, the luggage box 40 may also be made of resin with higher strength than the fuel tank tray 30.

[0021] According to the above (7) scheme, the suitcase is made of resin to reduce weight and ensures the strength of the suitcase compared to the fuel tank tray. In addition, the fuel tank tray is made as light as possible, which can reduce the material cost of the fuel tank tray.

[0022] (8) In the above-mentioned (1) solution, the second mounting part 46 may also be a fastening connection part, and a protrusion 49 extending upward from the fastening connection seat surface 47a in the second mounting part 46 is provided around it.

[0023] According to the above-described (8) solution, since the fastening connection seat surface has a protrusion that is higher than the fastening connection structure, the protrusion can be used as follows: that is, it can be used as a part to prevent items, fingers, etc. from contacting the fastening connection structure, or as a load support part that bears the load from the components of opening and closing the suitcase, or as a reporting component indicating the storage height limit of the suitcase.

[0024] (9) In the above-mentioned (1) solution, a seat 5 for the user to sit on is provided above the luggage compartment 40 and the fuel tank 15. The seat 5 is an opening and closing member for opening and closing the upper opening 44a of the luggage compartment 40. A sealing part 45d extending in the vehicle width direction is provided in the seat 5 at a position rearward than the user's sitting position 5c.

[0025] According to the above-described (9) solution, a sealing part is provided in the seat where the upper opening of the luggage compartment is opened and closed, positioned closer to the fuel tank 15 side than the user's seating position. Therefore, the height of the sealing part can be prevented from affecting the seat's performance. That is, when the luggage compartment extends upwards towards the fuel tank 15 side, the position of the sealing part also rises, which is thought to affect the height of the seating position and the thickness of the seat cushion. In contrast, by positioning the sealing part at a position away from the seating position towards the fuel tank side, the influence on the height of the seating position and the thickness of the seat cushion can be suppressed.

[0026] (10) In the above-mentioned (1) solution, the second mounting part 46 may be arranged as a pair of left and right in the vehicle width direction, and an item placement part 43 may be provided between the pair of second mounting parts 46 in the rear part 41 of the luggage compartment 40.

[0027] According to the above (10) scheme, the empty space between a pair of second mounting parts at the rear of the suitcase can be used to store small items such as tools, which can improve convenience.

[0028] (11) A second aspect of the present invention is a luggage compartment mounting structure for a vehicle, comprising: a fuel tank 15 supported on a vehicle body 1A; a luggage compartment 40 disposed on one side of the fuel tank 15 in a first direction orthogonal to the vertical direction; and a fuel tank tray 30 disposed above the fuel tank 15, wherein a portion 31 on the first direction side of the fuel tank tray is mounted to at least one of the vehicle body 1A and the fuel tank 15 via a first mounting portion 35, and a portion 41 on the other side of the first direction of the luggage compartment 40 is mounted to the fuel tank tray 30 via a second mounting portion 46, the second mounting portion 46 being located above the first mounting portion 35 and on the other side of the first direction.

[0029] According to the solution of the present invention, in the luggage compartment mounting structure of a vehicle having a luggage compartment and a fuel tank arranged in one direction, the capacity of the luggage compartment can be ensured without suppressing the capacity of the fuel tank.

[0063] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the directions (front, back, left, right, etc.) in the following description are the same as those in the vehicle described below. Furthermore, in the figures used in the following description, arrows indicating the front of the vehicle (FR), the left side of the vehicle (LH), the top of the vehicle (UP), and the center lines on the left and right sides of the vehicle body (CL) are shown in appropriate locations.

[0064] Figure 1 This is a left-side view of a small motorcycle-type motorized two-wheeled vehicle (horse-riding type vehicle) 1, viewed from the left-right direction (vehicle width direction), as an example of a vehicle. The motorized two-wheeled vehicle 1 has a front wheel 3 as a steering wheel and a rear wheel 4 as a drive wheel. The front wheel 3 is supported by a front fork 3a and can be steered via handlebars 2. The rear wheel 4 is supported by a swing-type power unit 8 and can be driven by the power unit 8. The steering system components, including the handlebars 2, front fork 3a, and front wheel 3, are steerably supported on the head tube 10a at the front end of the frame 10. The front part of the power unit 8 is sway-mounted and supported at the front-rear center of the frame 10 (not limited to the center). The power unit 8 includes a drive source 8a for vehicle movement and a transmission device 8b that transmits the driving force generated by the drive source 8a to the rear wheel 4. The drive source 8a may include, for example, an internal combustion engine. The drive source 8a may also include an electric motor.

[0065] A footrest 6 for the driver is provided between the front wheel 3 and the rear wheel 4. A front body 11 is provided in front of the footrest 6. A rear body 12 is provided behind the footrest 6. The space K1 between the front body 11 and the rear body 12 and above the footrest 6 serves as the straddle space K1 for the driver when straddling the vehicle body 1A. A handlebar 2 is positioned above the front body 11 and is covered by a handlebar cover 2a. A seat 5 for the passenger is positioned above the rear body 12. A tiltable side rack 7 is provided on the lower left side of the footrest 6, which supports the vehicle body 1A in an upright position tilted to the left. In this embodiment, the "vehicle body 1A" includes components fixed to the frame 10 in addition to the frame 10.

[0066] The frame 10 of the motorized two-wheeled vehicle 1 is covered by a body cover 20. The body cover 20 includes: a front central cover 21 that covers the front body 11 from the front; front side covers 22 that cover the front body 11 from the left and right sides; and an inner cover 23 that covers the front body 11 from the rear.

[0067] In addition, the body cover 20 has a bottom plate cover 24 that covers the bottom step 6 from above and bottom plate side covers 25 that cover the bottom step 6 from the left and right sides.

[0068] In addition, the body cover 20 has a rear central cover 26 that covers the rear body 12 from the front and a rear side cover 27 that covers the rear body 12 from the left and right sides.

[0069] The front center cover 21 and the front side cover 22 form the outer surface of the front body 11. The rear center cover 26 and the rear side cover 27 form the outer surface of the rear body 12. The upper surface of the floor cover 24 forms the footrest 24a of the footrest 6. The footrest 24a is, for example, flat across the entire width in the vehicle width direction. The footrest 6 may also have a central passage that rises upwards from the inside in the vehicle width direction.

[0070] The power unit 8 is a unit that integrates the engine (internal combustion engine) at the front with the power transmission mechanism on the rear left side. The rear wheel 4 is supported by an axle at the rear end of the power transmission mechanism. The rear end of the power transmission mechanism is supported by the rear end of the frame 10 via a rear buffer 9. Thus, a unit-type swing rear suspension is formed at the rear of the vehicle body.

[0071] <Chassis>

[0072] Reference Figure 1The frame 10 is constructed by joining various steel materials together in one piece through welding or other methods. The frame 10 includes a head tube 10a, a lower frame 10b extending rearward and downward from the head tube 10a, a lower frame 10c extending rearward from the lower part of the lower frame 10b, and a rear frame 10d extending rearward and upward from the rear part of the lower frame 10c. The rear frame 10d has a pair of left and right seat rails 10e. The left and right seat rails 10e extend rearward and upward from the left and right sides of a cross frame extending in the left-right direction, for example, at the rear end of the lower frame 10c.

[0073] The left and right seat rails 10e each have: a front extension 10f that extends backward and upward from the rear end of the lower frame 10c when viewed from the side; and a rear extension 10g that extends rearward from the rear end of the front extension 10f in a generally horizontal manner (more specifically, with a gentler slope than the front extension 10f, lower at the front and higher at the rear) when viewed from the side. The left and right front extensions 10f extend along the vehicle's longitudinal direction when viewed from above. The left and right rear extensions 10g extend backward from the rear end of the front extensions 10f in a slope that becomes more inward in the vehicle width direction as they move further back when viewed from above. The lower part of the luggage compartment 40 is located between the left and right front extensions 10f. The lower part of the fuel tank 15, which is trapezoidal in shape when viewed from above, is located between the left and right rear extensions 10g. The shape of the fuel tank 15 when viewed from above is similar to... Figure 3 , Figure 8 The same applies to the fuel tank tray 30 shown.

[0074] <Fuel Tank>

[0075] Reference Figure 2 , Figure 3 The fuel tank 15 includes: a hollow tank body 16 that is generally trapezoidal in shape when viewed from above; a fuel supply pipe 17 with its upper end protruding from the rear upper surface of the tank body 16; and a detachable tank cap 18, such as a screw-on type, installed at the upper end of the fuel supply pipe 17. The upper opening of the fuel supply pipe 17 forms a fuel inlet 17a of the fuel tank 15. The fuel inlet 17a can be opened and closed by removing and installing the tank cap 18.

[0076] The can body 16 is formed by joining upper and lower segments 16a and 16b together. When viewed from the side, the upper and lower segments 16a and 16b are divided by a front-low, rear-high dividing surface that is approximately parallel to the rear extension 10g of the seat track 10e. The upper segment 16a is shaped like a container opening downwards, and the lower segment 16b is shaped like a container opening upwards. The upper and lower segments 16a and 16b are both stamped steel sheet parts. Flanges are formed at the lower open end of the upper segment 16a and the upper open end of the lower segment 16b, respectively, and these two flanges are overlapped and welded together. When viewed from above, the entire circumference of the can body 16 has a can flange 16c that joins the two flanges together.

[0077] The tank body 16 is formed substantially symmetrically about the left and right center lines CL of the vehicle body. The tank body 16 is formed, for example, a trapezoidal shape that narrows in width towards the rear when viewed from above. The left and right sides of the tank body 16 are inclined along the rear extension 10g in the left and right seat tracks 10e, and the rear extension 10g is inclined in such a way that it is located further inward in the vehicle width direction towards the rear.

[0078] The tank body 16 includes: an upper surface portion and a lower surface portion that slope downwards from front to rear; a front surface portion between the front edges of the upper and lower surface portions; a rear surface portion between the rear edges of the upper and lower surface portions; and left and right side surface portions between the left and right side edges of the upper and lower surface portions. A cylindrical fuel supply pipe 17, which is orthogonal to the upper surface portion when viewed from the side, is disposed at the rear of the upper surface portion. The fuel supply pipe 17 is disposed such that it overlaps with the left and right center CL of the vehicle body when viewed from above. The upper opening of the fuel supply pipe 17 forms the fuel supply port 17a of the fuel tank 15. A shallow, container-shaped fuel supply tray 19 is fixed to the upper surface portion, surrounding the fuel supply pipe 17. The fuel supply tray 19 is circular in shape and coaxial with the fuel supply pipe 17 when viewed from above, and catches fuel that overflows or flows out to the periphery of the fuel supply pipe 17. A drain pipe 19a for guiding liquids such as fuel to the outside of the vehicle is connected to the left side of the bottom of the fuel supply tray 19 (side of the side parking rack 7). The oil supply tray 19 is made of steel plate and welded to the tank body 16, or is formed of a suitable material and can be detached from the tank body 16.

[0079] Reference Figure 2 , Figure 4 Left and right front can support brackets 16d are fixed to the upper front part of the rear extension 10g of the left and right seat rails 10e, respectively, to support the front two sides of the can flange 16c. Left and right rear can support brackets (not shown) are fixed to the upper rear part of the rear extension 10g of the left and right seat rails 10e (or to the cross frame between the rear parts of the left and right rear extensions 10g, etc.), respectively, to support the rear two sides of the can flange 16c.

[0080] Refer to together Figure 6 , Figure 7On the upper rear side of the rear extension 10g of the left and right seat tracks 10e, armrest support brackets 16f are respectively fixed for fixing a pair of left and right auxiliary armrests 13 arranged on both sides of the rear of the seat 5. The armrest support bracket 16f has front and rear legs 16f1 and 16f2 extending in the vertical direction and a mounting part 16f3 extending in the vertical direction between the upper parts of the front and rear legs 16f1 and 16f2. The upper ends of the front and rear legs 16f1 and 16f2 become fastening connection parts for fastening and connecting to the fixing plate 13a extending from the lower surface of the auxiliary armrest 13 in the vehicle width direction. The symbol B3 in the figure indicates a bolt screwed into the upper ends of the front and rear legs 16f1 and 16f2. The rear of the left and right auxiliary armrests 13 are connected by an aesthetically designed end plate 13c.

[0081] The rear of the fixing plate 13a of the left and right auxiliary armrests 13 is connected in the left-right direction via a horizontal plate 13b that runs across the rear of the fuel supply pipe 17. The horizontal plate 13b supports the rear of the fuel tank tray 30 from below. An extension 13a1 extending inward in the vehicle width direction is formed at the front of the fixing plate 13a of the left and right auxiliary armrests 13. The left and right extensions 13a1 support the front sides of the fuel tank tray 30 from below.

[0082] <Fuel Tank Tray>

[0083] Reference Figure 2 , Figure 3 , Figure 8 A fuel tank tray 30 is disposed above the upper surface of the fuel tank 15. The fuel tank tray 30 is a flat plate that is generally parallel to the upper surface of the fuel tank 15, and when viewed from above, it forms a roughly trapezoidal shape that largely overlaps with the fuel tank 15. In the figure, symbol 30a represents the left and right side edges of the fuel tank tray 30 when viewed from above, symbol 30b represents the rear edge of the fuel tank tray 30 when viewed from above, and symbol 30c represents the front edge of the fuel tank tray 30. The left and right side edges 30a extend obliquely, becoming more inward in the vehicle width direction as they move further back. The rear edge 30b extends between the rear ends of the left and right side edges 30a, and when viewed from above, it forms a shallow V-shape that bulges rearward. The front edge 30c extends in the left and right direction and is disposed below the upper rear part 41 of the trunk 40.

[0084] The fuel tank tray 30 is integrally formed, for example, from a synthetic resin such as polypropylene. By having the fuel tank tray 30, which is a one-piece resin molded part, cover the top of the fuel tank 15, which is a steel plate assembly, the appearance of the structure under the seat 5 when the seat 5 is open can be improved through the appearance design of the fuel tank tray 30.

[0085] The fuel tank tray 30 is a resin component with a lower density than the frame components of the metal frame 10 (particularly the seat rail 10e). The fuel tank tray 30 is a component with a lighter weight per unit volume than the frame components of the frame 10.

[0086] An opening 32 is formed at the rear of the fuel tank tray 30, through which the fuel supply pipe 17 passes. The opening 32 is circular in shape, larger than the diameter of the fuel supply pipe 17, allowing the tank cover 18 to be installed or removed from above the fuel tank tray 30. The opening 32 is smaller than the diameter of the fuel supply tray 19 on the fuel tank 15, suppressing the exposure of structures outside the fuel supply tray 19. A cylindrical inner peripheral wall 32a extends downward from the inner peripheral edge of the opening 32, facing the inside of the fuel supply tray 19. This inner peripheral wall 32a also suppresses the exposure of structures outside the fuel supply tray 19. Fuel overflowing or flowing around the fuel supply pipe 17 is caught by the fuel supply tray 19 through the opening 32. Liquids such as fuel accumulated in the fuel supply tray 19 are guided out of the vehicle, for example, from the bottom of the fuel supply tray 19 through the drain pipe 19a.

[0087] An upwardly protruding peripheral protrusion 33 is formed on the upper surface of the fuel tank tray 30. The peripheral protrusion 33, when viewed from above, surrounds the left, right, and rear sides of the opening 32. The peripheral protrusion 33 includes: left and right side edge protrusions 33a, located inside the left and right side edges 30a in the vehicle width direction and extending substantially parallel to each side edge 30a when viewed from above; and a rear edge protrusion 33b, extending along the rear edge 30b (substantially overlapping) when viewed from above. The peripheral protrusion 33 is formed at a height that overlaps vertically with the outer peripheral edges (left, right, and rear edges) of the rear of the seat 5 when the seat 5 is closed. The peripheral protrusion 33 suppresses the possibility of the gap between the seat 5 and the fuel tank tray 30 being visually confirmed from the left, right, and rear sides when the seat 5 is closed.

[0088] A locking mechanism 34, which can lock the seat 5 in a closed position, is located below the rear of the fuel tank tray 30 and behind the fuel tank 15. (See reference) Figure 2 A locking opening 34a (not shown) is formed in the fuel tank tray 30, located behind the opening 32, allowing a striker (not shown) fixed to the base plate 5e of the seat 5 to reach the locking mechanism 34. The seat 5 rotates (opens and closes) vertically about a hinge axis 5a located at the front end in the left-right direction. From a closed state where the upper surface, i.e., the seating surface 5b, is approximately horizontal, the seat 5 opens (rotates) by moving the rear end upwards, reaching an open state where the seating surface 5b is approximately vertical. At this time, components such as the luggage compartment 40 and the fuel tank 15 under the seat 5 can be reached.

[0089] The front portion 31 of the fuel tank tray 30 is mounted to the vehicle frame 10 (left and right seat rails 10e) via a pair of left and right first mounting portions 35. Each first mounting portion 35 includes: a bottom 36a of a bottomed cylindrical support leg 36 integrally formed on the fuel tank tray 30; and a front tank support bracket 16d fixed to the left and right seat rails 10e by welding or the like. The support legs 36 are separately arranged on the left and right sides of the front portion 31 of the fuel tank tray 30, and the front tank support bracket 16d is separately arranged on the left and right seat rails 10e. The vertical length L1 of the support legs 36 is longer than the vertical length L2 of the front tank support bracket 16d. The front tank support bracket 16d can also be fixed to the fuel tank 15.

[0090] The front portion 31 of the fuel tank tray 30 has a plurality of (a pair of front and rear) grooves 37a and 37b extending in the left-right direction between the left and right support legs 36 and the left and right second mounting portions 46 (described later). The structure of the grooves 37a, 37b, etc., can improve the rigidity of the beam portion between the left and right second mounting portions 46. Ribs or other legs 38 are appropriately formed on the lower surface side of the fuel tank tray 30, abutting against the upper surface portion of the fuel tank 15, etc.

[0091] The front portion 31 of the fuel tank tray 30, excluding its left and right outer ends, is positioned below the upper rear portion 41 of the luggage compartment 40. An upwardly extending guide wall 39 is formed on the upper surface of the front portion 31 of the fuel tank tray 30. The guide wall 39 is formed along the left and right side edges 41a and the rear edge 41b of the upper rear portion 41 of the luggage compartment 40 when viewed from above. When the front portion 31 of the fuel tank tray 30 covers the upper rear portion 41 of the luggage compartment 40, the guide wall 39 enters and fits into the inner side of the left and right side edges 41a and the rear edge 41b of the upper rear portion 41 of the luggage compartment 40 (see reference). Figure 5 This is to prevent impurities from entering between the fuel tank tray 30 and the luggage compartment 40.

[0092] The fuel tank tray 30 is mounted on the vehicle frame 10 together with the fuel tank 15. When mounting the fuel tank tray 30 and the fuel tank 15 on the vehicle body 1A, for example, the fuel tank 15 is first positioned in the mounting position on the vehicle body 1A, such that the fastened connecting portion 16c1 at the front of the tank flange 16c abuts against the front tank support bracket 16d fixed to the left and right seat rails 10e, and the fastened connecting portion (not shown) at the rear of the tank flange 16c abuts against the rear tank support bracket (not shown) fixed to the vehicle body 1A (or the fuel tank 15) on the left and right seat rails 10e, etc.

[0093] Next, the fuel tank tray 30 is positioned above the fuel tank 15. At this time, the left and right support legs 36 abut against the fastened connection portion 16c1 at the front of the tank flange 16c, clamping the fastened connection portion 16c1 between the bottom 36a of the support legs 36 and the upper end of the front tank support bracket 16d. Furthermore, the clamping insert portions (fastening connections) 34b, located at the rear of the fuel tank tray 30 and on both sides of the locking opening 34a, abut against the upper ends of the rear support bracket (not shown) of the tray, which is located on both sides of the locking mechanism 34 and supported on the vehicle body 1A. The fuel supply pipe 17, viewed from above, is positioned within the opening 32 of the fuel tank tray 30.

[0094] Then, bolt B1 is passed through from above into the bolt insertion hole formed in the fastening connection portion 16c1 at the bottom 36a of the support leg 36 and the front of the tank flange 16c, and bolt B1 is screwed into the nut provided at the upper end of the front tank support bracket 16d, thereby fastening and fixing the front parts of the fuel tank 15 and the fuel tank tray 30 together to the vehicle body 1A. Additionally, bolts are passed through from above into the bolt insertion hole formed in the fastening connection portion (not shown) at the rear of the tank flange 16c, and bolts are screwed into the nut provided at the upper end of the rear tank support bracket (not shown), thereby fastening and fixing the rear part of the fuel tank 15 to the vehicle body 1A. Furthermore, clip C1 is inserted into the clip insertion portion 34b at the rear of the fuel tank tray 30, and clip C1 is locked into the upper end of the rear support bracket (not shown), thereby fixing the rear part of the fuel tank tray 30 to the vehicle body 1A.

[0095] Each mounting part of the fuel tank 15 may also have an elastic body such as a supporting buffer rubber sandwiched between the fuel tank 15 and the vehicle body 1A. The fuel tank 15 and the fuel tank tray 30 can be assembled to the vehicle body 1A as a pre-assembled unit.

[0096] <Luggage>

[0097] Reference Figure 1 , Figure 3 , Figure 5A luggage compartment 40 is located below the seat 5 and in front of the fuel tank 15. The fuel tank 15 and the luggage compartment 40 are positioned at a height that overlaps each other in the vertical direction. The luggage compartment 40 is shaped like an upwardly opening container, forming a recessed area (item storage section) 42 for storing items such as helmets. A relatively shallow rear shelf section 43 for placing vehicle tools is formed behind the upper part of the recessed area 42 in the luggage compartment 40. The rear shelf section 43 is located on the upper rear part 41 of the luggage compartment 40. The upper rear part 41 is provided to extend upward and backward at an angle. The upper end 44 of the luggage compartment 40 is formed to extend radially along the center of the hinge axis 5a as a whole when viewed from the side. The hinge axis 5a of the seat 5 is located lower than the seating surface 5b. Therefore, the upper end 44 of the luggage compartment 40 extends at an angle that is lower in the front and higher in the back (i.e., higher in the back and lower in the front) when viewed from the side.

[0098] The luggage compartment 40 is made of synthetic resin with higher strength than the fuel tank tray 30, for example, by integral molding of polypropylene mixed with glass fiber. The luggage compartment 40 is a resin component with a lower density than the frame components of the metal frame 10. The luggage compartment 40 is a component with a lighter weight per unit volume than the frame components of the frame 10.

[0099] The upper end portion 44 of the luggage compartment 40 forms an upwardly opening upper opening 44a and an edge portion 45 extending along the periphery of the upper opening 44a. The edge portion 45 includes: an inner peripheral wall 45a facing the upper opening 44a of the luggage compartment 40; an upper wall 45b extending from the upper end of the inner peripheral wall 45a to the outer peripheral side; and an outer peripheral wall 45c extending downwardly from the outer peripheral end of the upper wall 45b. The edge portion 45 has an upwardly protruding trapezoidal cross-sectional shape and extends along the entire circumference of the upper opening 44a. The flat upper end surface of the edge portion 45 (the upper surface of the upper wall 45b) becomes a sealing surface for the sealing member 5f held on the base plate 5e of the seat 5 to be tightly sealed.

[0100] The sealing rear portion 45d, extending along the rear edge 41b in the vehicle width direction, is positioned rearward of the driver's seating position 5c in the seat 5. The portion of the retaining sealing member 5f in the floor 5e protrudes upward to form a retaining structure for the sealing member 5f. Therefore, the thickness of the seat cushion 5e1 of the seat 5 is easily reduced directly above the sealing member 5f. In contrast, the sealing rear portion 45d, extending along the rear edge 41b in the vehicle width direction, is positioned rearward of the driver's seating position 5c, thereby suppressing the reduction of the seat cushion thickness of the seat 5. In this embodiment, the sealing rear portion 45d is positioned between the front and rear seating positions 5c and 5d and below the step portion (backrest) 5g where the seat cushion 5e1 protrudes upward. This ensures that the sealing position avoids the front and rear seating positions 5c and 5d, and guarantees the seat cushion thickness at the sealing position. The area below the step 5g is not limited to directly below the apex 5g1 of the step 5g. Even at positions where the apex 5g1 is offset forward or backward, the thickness of the seat cushion of the step 5g is allowed to deviate to a certain degree.

[0101] When the upper part 44 (upper opening 44a) of the suitcase 40 is tilted with the front lower than the back, large items such as helmets protrude upwards beyond the upper opening 44a. On the other hand, the base plate 5e of the seat 5, which closes the upper opening 44a, has an upwardly convex curved shape, which to some extent allows items to protrude upwards beyond the upper opening 44a.

[0102] The rear portion of the edge portion 45 surrounds the rear and left and right sides of the rear shelf portion 43. The rear shelf portion 43, when viewed from above, is a rectangular shape that is longer from left to right. The front edge 43a of the rear shelf portion 43 is flat, and the rear wall 42a of the receiving recess 42 hangs downward from the front edge 43a of the rear shelf portion 43. Alternatively, an upwardly protruding protrusion may be formed on the front edge 43a of the rear shelf portion 43 to restrict the forward movement of items placed on the rear shelf portion 43.

[0103] The front part 31 of the fuel tank tray 30 extends below the rear shelf part 43. The rear shelf part 43 and the front part 31 of the fuel tank tray 30 overlap when viewed from above, and are joined together at the second mounting part 46, which will be described later.

[0104] <Rear fastening connection structure of the suitcase>

[0105] Reference Figures 2-4The upper rear portion 41 of the luggage compartment 40 is mounted only to the front portion 31 of the fuel tank tray 30 at the second mounting portion 46. The second mounting portion 46 is located above and behind the first mounting portion 35 that mounts the fuel tank tray 30 to the vehicle body 1A. The second mounting portion 46 includes: a compartment-side fastening connection portion 47 formed on the upper rear portion 41 of the luggage compartment 40; and a tray-side fastening connection portion 48 formed on the front portion 31 of the fuel tank tray 30. The compartment-side fastening connection portion 47 is separately arranged on the left and right sides of the upper rear portion 41 of the luggage compartment 40, and the tray-side fastening connection portion 48 is separately arranged on the left and right sides of the front portion 31 of the fuel tank tray 30. That is, the second mounting portions 46 are provided as a pair, left and right.

[0106] The left and right second mounting portions 46 are respectively positioned inside the left and right first mounting portions 35 in the vehicle width direction. The left and right second mounting portions 46 are respectively close to the left and right first mounting portions 35 on the same side, and their front-to-back position overlaps with at least a portion of the first mounting portion 35. The vehicle width position of each of the left and right second mounting portions 46 also overlaps with at least a portion of the left and right first mounting portions 35 on the same side. The front portion 31 of the fuel tank tray 30 has increased rigidity through a plurality of grooves 37a, 37b, etc., between the left and right second mounting portions 46.

[0107] In the second mounting portion 46, a bolt insertion hole is formed in the upper box-side fastening connection portion 47, and a nut is provided in the lower tray-side fastening connection portion 48. With the box-side fastening connection portion 47 and the tray-side fastening connection portion 48 overlapping each other, the bolt B2 is passed through the bolt insertion hole of the box-side fastening connection portion 47 from above, and the bolt B2 is screwed into the nut of the tray-side fastening connection portion 48, thereby fastening and fixing the box-side fastening connection portion 47 and the upper rear part 41 of the luggage compartment 40 to the tray-side fastening connection portion 48 and the front part 31 of the fuel tank tray 30.

[0108] Around the fastening seat surface 47a of the left and right side fastening connection portions 47, a seat surface protrusion 49 is formed that protrudes upward from the head of the bolt B2 in the fastened state. The seat surface protrusion 49 has, for example, an upwardly protruding trapezoidal cross-sectional shape and extends in an arc shape when viewed from above. The seat surface protrusion 49 extends in such a way that it surrounds the head of the bolt B2 from its front to its inner side in the vehicle width direction. The corner portions 45e (arc-shaped bends when viewed from above) on both sides of the rear portion of the edge portion 45 of the upper end 44 of the trunk 40 from the inner peripheral side. Therefore, the head of the bolt B2 of the trunk side fastening connection portion 47 is surrounded by the corner portions 45e of the edge portion 45 from its outer side in the vehicle width direction to its rear.

[0109] The protrusion height of the seat protrusion 49 relative to the flat portion (rear shelf portion 43) of the upper rear part 41 of the luggage compartment 40 is lower than the protrusion height of the edge portion 45 relative to the flat portion (rear shelf portion 43) of the upper rear part 41 of the luggage compartment 40. The sealing member 5f held in the base plate 5e of the seat 5 is in close contact with the flat upper end surface of the edge portion 45, and the bulge 5e2 in the base plate 5e of the seat 5, which bulges downward from the sealing member, abuts against the flat upper end surface of the seat protrusion 49. As a result, a portion of the seat load can be borne near the second mounting portion 46. The portion of the upper rear part 41 of the luggage compartment 40 between the left and right second mounting portions 46 is reinforced by the rear portion of the edge portion 45, and the portion of the front part 31 of the fuel tank tray 30 between the left and right second mounting portions 46 is reinforced by a plurality of grooves 37a, 37b. Therefore, the area between the left and right second mounting portions 46 is also strong in its ability to withstand loads from above, and the loads supported by this area can be transmitted to the seat track 10e via the support legs 36 of the left and right first mounting portions 35.

[0110] As explained above, the luggage compartment mounting structure in the above embodiment is characterized by having a fuel tank 15 supported on the vehicle body 1A, a luggage compartment 40 disposed on one side (front side) of the fuel tank 15 in a first direction (front-rear direction) orthogonal to the vertical direction, and a fuel tank tray 30 disposed above the fuel tank 15. The portion (front 31) of the fuel tank tray 30 on the first direction side is mounted to at least one of the vehicle body 1A and the fuel tank 15 via a first mounting portion 35. The portion (rear upper 41) of the luggage compartment 40 on the other side (rear side) of the first direction is mounted to the fuel tank tray 30 via a second mounting portion 46, which is located above the first mounting portion 35 and on the other side of the first direction.

[0111] According to this structure, the portion of the luggage compartment 40 located on the first direction side (front side) of the fuel tank 15 is mounted on the fuel tank tray 30 located above the fuel tank 15. Therefore, compared to a structure where the portion of the luggage compartment 40 on the first direction side is mounted on a cross frame or similar structure located between the fuel tank 15 and the luggage compartment 40, the portion of the luggage compartment 40 on the first direction side can extend upwards towards the fuel tank 15 side. Thus, the capacity of the luggage compartment 40 on the fuel tank 15 side can be further ensured without restricting the capacity of the fuel tank 15.

[0112] The portion of the luggage compartment 40 on the other side of the first direction is mounted to the fuel tank tray 30 at a second mounting portion 46, which is different from the first mounting portion 35 for mounting the fuel tank 15. Therefore, compared to a structure where the fuel tank 15 and the luggage compartment 40 share a mounting portion, one of the fuel tank 15 and the luggage compartment 40 can be installed or removed without being affected by the installation state of the other. Thus, the installation and removal of the fuel tank 15 and the luggage compartment 40 become easier, improving the maintainability of the motorized two-wheeled vehicle 1. In particular, when the power unit 8 of the motorized two-wheeled vehicle 1 is located below the luggage compartment 40, the maintainability of the power unit 8 is also improved.

[0113] Furthermore, in the above-described luggage mounting structure, the luggage 40 is characterized in that the portion on the other side of the first direction is mounted to the fuel tank tray 30 only via the second mounting portion 46.

[0114] According to this structure, compared with the structure that also installs the part of the luggage compartment 40 on the other side of the first direction outside the fuel tank tray 30 (fuel tank 15, body 1A, etc.), the position of the second mounting part 46 can be set without depending on the position of other structures, which can improve the design freedom of the area around the part of the luggage compartment 40 on the other side of the first direction.

[0115] Furthermore, in the above-mentioned luggage compartment mounting structure, the fuel tank 15 and the fuel tank tray 30 are mounted together on the vehicle body 1A in the first mounting part 35.

[0116] According to this structure, in the first mounting part 35, the fuel tank tray 30 and the fuel tank 15 are mounted to the vehicle body 1A by common fastening, etc., thus simplifying the mounting structure of the fuel tank tray 30 and the fuel tank 15.

[0117] Furthermore, in the above-described luggage compartment mounting structure, the first mounting part 35 and the second mounting part 46 are respectively arranged as a pair in a second direction (left-right direction, vehicle width direction) orthogonal to the above-described vertical direction and the first direction, and the second mounting part 46 for mounting the luggage compartment 40 is positioned inside the second direction than the first mounting part 35 for mounting the fuel tank tray 30.

[0118] According to this structure, the pair of second mounting portions 46 for mounting the luggage compartment 40 are positioned more inward in the second direction than the pair of first mounting portions 35 for mounting the fuel tank tray 30. Therefore, the first mounting portions 35 and the second mounting portions 46 can be positioned close to each other in the first direction without depending on the configuration of the other, thereby increasing the degree of freedom in the configuration of the first mounting portions 35 and the second mounting portions 46.

[0119] Furthermore, in the above-mentioned luggage compartment mounting structure, the vehicle body 1A is characterized by having a pair of frame members (seat rails 10e) supporting the fuel tank 15 in the second direction, and the pair of the first mounting portions 35 are separately disposed on the pair of the frame members.

[0120] According to this structure, since a pair of first mounting portions 35 are separately arranged on each pair of frame members, the first mounting portions 35 are positioned on the outer side in the second direction and are easily accessible to the operator, thus improving the workability of the first mounting portions 35. In addition, compared with the case where the first mounting portions 35 are arranged on the cross frame between a pair of frame members, the design freedom of the cross frame and the frame 10 can be increased.

[0121] Furthermore, in the above-described luggage mounting structure, the fuel tank tray 30 is characterized by being made of resin that is lighter per unit weight than the metal frame member, and the fuel tank tray 30 has a support leg 36 that extends downward from the tray body toward the frame member, and includes the structure (bottom 36a) of the first mounting portion 35 at the lower end.

[0122] According to this structure, the support leg 36 constituting the first mounting part 35 extends from the fuel tank tray 30, which is lighter than the frame member, toward the frame member, thereby achieving weight reduction compared to the case where a metal bracket or the like is extended from the frame member to mount the fuel tank tray 30.

[0123] Furthermore, in the above-mentioned luggage mounting structure, the luggage 40 is characterized in that it is made of resin with higher strength than the fuel tank tray 30.

[0124] Based on this structure, the suitcase 40 is made of resin to reduce weight, and its strength is ensured compared to the fuel tank tray 30. In addition, the fuel tank tray 30 is made as light as possible, which reduces the material cost of the fuel tank tray 30.

[0125] Furthermore, in the above-described luggage mounting structure, the second mounting part 46 is a fastening connection part, and a seat protrusion 49 extending upward from the fastening connection seat surface 47a in the second mounting part 46 is provided around it.

[0126] According to this structure, since a seat protrusion 49 higher than the fastening connecting member is provided around the fastening connecting seat surface 47a, the seat protrusion 49 can be used as follows: that is, it can be used as a part to prevent items, fingers, etc. from contacting the fastening connecting member, or as a load support part to bear the load from the components of opening and closing the suitcase 40, or as a reporting member indicating the storage height limit of the suitcase 40.

[0127] Furthermore, in the above-described luggage installation structure, the feature is that a seat 5 for the user is provided above the luggage 40 and the fuel tank 15. The seat 5 is an opening and closing member for opening and closing the upper opening 44a of the luggage 40. A sealing part (sealing rear part 45d) for sealing the luggage 40 and the seat 5 is provided on the side of the seat 5 that is further away from the user's seating position 5c in the first direction.

[0128] According to this structure, a sealing portion (rear sealing portion 45d) is provided in the seat 5, which opens and closes the upper opening 44a of the luggage compartment 40, at a position closer to the fuel tank 15 than the user's seating position 5c. Therefore, the height of the sealing portion can be prevented from affecting the performance of the seat 5. That is, when the luggage compartment 40 extends upward toward the fuel tank 15 side, the position of the sealing portion also rises, which is thought to affect the height of the seating position 5c and the thickness of the seat cushion 5e1. In contrast, by providing the sealing portion at a position that avoids the seating position 5c on the fuel tank 15 side, the influence on the height of the seating position 5c and the thickness of the seat cushion 5e1 can be suppressed.

[0129] Furthermore, in the above-described luggage mounting structure, the feature is that an item placement section (rear shelf section 43) is provided between a pair of the second mounting sections 46 in the portion (upper rear section 41) on the other side of the first direction of the luggage 40.

[0130] According to this structure, the space between a pair of second mounting parts 46 on the other side of the first direction of the suitcase 40 can be used to place small items such as tools, which can improve convenience.

[0131] This invention is not limited to the above-described embodiments. For example, in one embodiment, it is applicable to a motorized two-wheeled vehicle 1 in which a luggage compartment 40 and a fuel tank 15 are arranged under the seat 5, but it is not limited thereto. For example, it could be as follows: Figure 9 , Figure 10 As shown in vehicles 101 and 201, at least one of the luggage compartment 40 and the fuel tank 15 is not positioned under the seat 5. Furthermore, the arrangement is not limited to having the fuel tank 15 positioned behind the luggage compartment 40; it could also be positioned in front of the luggage compartment 40. In the figures, symbol A represents one of the luggage compartment 40 and the fuel tank 15, and symbol B represents the other. Figure 9 An example is shown of a vehicle 101 with straddle space K1. Figure 10 The example shown is a vehicle 201 with a knee clip (KG). Furthermore, the arrangement is not limited to a configuration where the luggage compartment 40 and fuel tank 15 are arranged in a front-to-back direction; other configurations could also be as follows... Figure 11As shown in the vehicle 301, the luggage compartment 40 and the fuel tank 15 are arranged in a left-right direction.

[0132] The structure of this embodiment can also be applied to straddle-type vehicles other than motorized two-wheelers. The aforementioned straddle-type vehicles include all vehicles where the driver straddles the vehicle, including not only motorized two-wheelers (including bicycles and small motorcycles with a prime mover), but also three-wheeled (including vehicles with two front wheels and one rear wheel, as well as vehicles with two front wheels and one rear wheel) or four-wheeled (four-wheeled carts, etc.) vehicles. Furthermore, it can also be applied to vehicles whose prime mover includes an electric motor. Additionally, it can be applied to vehicles other than straddle-type vehicles (passenger cars, buses, trucks, etc.).

[0133] The structure of this embodiment is applicable to vehicles, but the invention is not limited to vehicles. It can also be applied to various transportation equipment such as aircraft and ships, as well as various means of transportation and mobile bodies such as construction machinery and industrial machinery. Moreover, in addition to vehicles, the invention can be widely applied to any device with a luggage compartment and fuel tank, such as push lawnmowers and sweepers.

[0134] Furthermore, the structure described above is an example of the present invention, and the constituent elements of the embodiment can be replaced with well-known constituent elements, etc., and various changes can be made without departing from the spirit of the present invention.
