DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle such as a scooter-type motorcycle, and particularly to a vehicle body structure for storing articles under the seat of the vehicle.

[Prior Art] A scooter-type motorcycle has a frame that is bent downward between the front fork and the seat.
A footrest for the driver is installed at the bottom of this bend. For this reason, the space between the front fork and the seat is occupied as a space for accommodating the driver's feet, and the engine cannot be installed in this area, so the engine is
It is integrated with a belt automatic transmission and is located below the seat.

In conventional scooter-type motorcycles, the seat is supported on the rear upper surface of the frame, and the space created below the seat is used as a storage space for items.

[Problems to be Solved by the Invention] However, in the conventional configuration described above, the seat is supported on the rear upper surface of the frame, so this frame is located above the storage space. Therefore, the size of the storage space is limited by the presence of the frame, and there is a problem that a large storage space cannot be obtained.

The present invention was made based on the above circumstances, and when installing a storage box under the seat, the storage box can be moved vertically, horizontally, and longitudinally without being obstructed by the frame or shock absorber. The length can be made large, and this storage box has the function of protecting the rear wheels from mud while ensuring sufficient capacity. By supporting the entire seat with a long storage box from front to back, the seat can be It can firmly support the seat, prevent deformation of the seat and decrease in storage space due to this deformation, and even though the storage box has a large capacity, it does not make you feel like you are taking up much storage space. An object of the present invention is to provide a body structure for a scooter type vehicle which can obtain a good appearance, can also ensure the length of a shock absorber for suspending an engine unit, and contributes to improvement of riding comfort.

[Means for Solving the Problems] Therefore, in the present invention, the lower end portion of the frame member extending downward from the head pipe is extended rearward, and the rear portion of this extended portion is raised to form a frame, Above the rising part of this frame, a seat extending in the front-rear direction is arranged, and behind the rising part, a swing-type engine unit is installed in which the engine and rear wheels are integrated and can swing in the vertical direction. The present invention assumes a scooter-type vehicle in which a shock absorber is placed between the rear of the engine unit and the rear of the frame.

A storage box is provided between the engine unit and the seat, protruding above the frame and having a length extending approximately from front to back of the seat. It has a box shape with an open top surface and a peripheral wall connected to the peripheral edge of the storage box, and the fixing part between the bottom plate and the frame of the storage box is located inside the storage space surrounded by the peripheral wall, The upper seat of the storage box has its front end connected via a hinge to the front end of the peripheral wall of the storage box so as to be rotatable in the front-rear direction,
This sheet opens and closes the top opening of the storage box, and the portion of the sheet behind the hinge is supported on both left and right sides of the peripheral wall of the storage box, and
The rear part of the storage box is located above the rear wheel,
A connector between the upper end of the shock absorber and the frame is located under the bottom plate of this storage box, and the lowest point of the bottom plate of this storage box is lower than the connection between the buffer and the frame. It is characterized by a cover that extends from the periphery of the storage box to above the engine unit and is continuous with the seat.

[Function] According to this configuration, since the seat is attached to the storage box that protrudes above the frame, the storage box and its top opening are not limited in size by the shape of the frame, and Brackets for supporting the seat can be omitted, and a large space for installing a storage box can be secured between the seat and the frame.

In addition, since the part that fixes the storage box to the frame does not need to protrude around the storage box, there is no need to form a relief on the surrounding wall when fixing the storage box to the frame, and the surrounding wall can be By extending it so that it overhangs, you can increase the capacity and opening shape of the storage box.

From the above, it is possible to ensure a sufficient capacity of the storage box, and large items can be accommodated without difficulty.

Furthermore, since the storage box covers the rear wheel from above while maintaining its box shape, this storage box functions as a mud guard to prevent mud from splashing upwards on the rear wheel. It can prevent movement, etc. from adhering to the inside.

In addition, since the front end of the seat and the middle part in the longitudinal direction are supported by a storage box that extends almost the entire length of the seat, the entire seat can be firmly supported.
Even when an occupant is seated on the seat, the seat does not deform upward or downward and the bottom of the seat does not fit into the top opening of the storage box, which undesirably reduces the storage space within the storage box. I don't have to worry about it.

Furthermore, since the storage box is covered with a cover, even though there is a large storage box under the seat, this storage box is not exposed to the outside, which maintains a good appearance. can do.

Furthermore, the upper end of the shock absorber that suspends the engine unit is connected to the rear part of the frame that stands up, and the bottom plate of the storage box protrudes downward to avoid the connection between the shock absorber and the frame. Therefore, while forming the storage box itself deep vertically,
The mounting position of the upper end of the shock absorber can be raised, and the length of the shock absorber can be secured.
Therefore, the swing stroke of the engine unit in the vertical direction can be increased, and the riding comfort can be improved accordingly.

As shown in FIG. 3, a support plate 27 that straddles the opening 18a of the storage box 18 in the left-right direction is bolted to the flange portion 21 of the storage box 18.
This support plate 27 is supported on both left and right sides of the peripheral wall 20 of the storage box 18. A rubber damper 28 is attached to the lower surface of the support plate 27, and this support plate 27 connects the fuel tank 22 and oil tank 23 to the bottom plate 19 of the housing box 18 via the rubber damper 28.
It is pressed against and fixed in position. In addition, the bottom plate 19 of the storage box 18 also serves as a mud guard that covers the upper part of the rear wheel 13.
This prevents mud from splashing onto the fuel tank 22, etc.

Note that the rear end of the bottom plate 19 has a through hole 3 for draining water.
5 is opened, and a bracket 17 at the rear end of the support portion 14 also has the function of connecting the shock absorber 15 to the frame member 3.

At the front end of the flange portion 21 of the storage box 18,
A seat 30 extending in the front-rear direction via a hinge 29
The front end portion of is rotatably supported. sheet 3
The seat bottom plate 31 of 0 is connected to the opening 18 of the storage box 18.
The lower surface of the front end side of the seat bottom plate 31 contacts the upper surface of the battery 25 via the rubber damper 35, and the battery 25
is holding down. Furthermore, this seat bottom plate 31
A support damper 34 is provided at an intermediate lower surface in the front-rear direction. The support damper 34 is connected to the support plate 27
Due to this contact, the intermediate portion of the seat 30 in the front-rear direction is supported by the left and right sides of the peripheral wall 20 of the storage box 18 via the support plate 21.

Therefore, the seat 30 is pivotally supported in the storage box 18 so as to be openable and closable, with its front end serving as a pivot point and its rear end pivoting upward.
0, the fuel tank 22, oil tank 23, battery 25, etc. inside the storage box 18 are exposed to the outside. For this reason, storage box 18
has a length that extends approximately to the front-to-back length of the seat 30, and the front-to-back length is formed to be sufficiently large.

The periphery of the storage box 18 is covered by a cover 32 that extends to the sheet 30. The lower part of the cover 32 continuously covers the area around the engine 11 of the engine unit 10, and the front part of the cover 32 also integrally covers the rising part 5 of the frame member 3, and the lower edge of the front end of the cover 32 covers the area around the engine 11 of the engine unit 10. It is continuous with the rear end of the placing plate 8. Therefore, the lower part of the seat 30 is integrally covered and hidden by the cover 32.

Note that a carrier 33 is arranged behind the seat 30, and this carrier 33 is bolted to the flange portion 21 of the storage box 18.

According to this configuration, the storage box 18 that projects upward from the support section 14 of the frame member 3 is attached, and the sheet 30 is attached to the opening edge at the top of the storage box 18. , a storage box 18 is provided between the seat 30 and the frame member 3.
A large space can be secured for installing the storage box 18, and the size of the storage box 18 is not restricted by the shape of the frame member 3.

Moreover, in the rear half 18b of the storage box 18, the bottom plate 19 protrudes below the connection part between the upper end of the shock absorber 15 and the support part 14 of the frame member 3. The dimensions can be made large. At the same time, since the rear half 18b of the storage box 18 reaches above the rear wheel 13, the size of the storage box 18 in the front-rear direction can also be made large.

Furthermore, since the fixing portions of the storage box 18 to the frame member 3 are located inside the storage space surrounded by the peripheral wall 20 of the storage box 18, the fixing portions are located on both left and right sides of the storage box 18 and in the front. There is no need to overhang. Therefore, since the storage box 18 can be fixed to the frame member 3 through the opening 18a, there is no need to form an escape in the peripheral wall 20 when fixing the storage box 18 to the frame member 3, and the peripheral wall By extending the storage box 20 so as to project around it, the capacity and opening shape of the storage box 18 can be increased.

Therefore, since the storage box 18 is large in the front-rear, left-right, and up-down directions, its capacity can be ensured sufficiently, and large items can be accommodated without difficulty.

At the same time, since the storage box 18 is installed on the support portion 14 at the rear end of the frame member 3, the frame member 3 does not get between the circumferential surface of the storage box 18 and the cover 32. Therefore, the peripheral wall 20 of the storage box 18 can be brought close to the cover 32, and the capacity of the storage box 18 can be increased accordingly, and the shape of the opening 18a can also be made larger, making it easier to take items in and out. can be done.

In addition, since the storage box 18 also has the function of supporting the seat 30, the frame 1 to the seat 3
Brackets for supporting 0 can be omitted. From this, not only can the structure of the frame 1 be simplified, but also the storage box 18 can be extended to the area where the brackets are no longer present, and in this respect, it is possible to increase the size of the storage box 18. It will contribute. In this case, storage box 18
has a length that extends approximately to the front and back length of the seat 30, and the seat 3 is located on both left and right sides of the peripheral wall 20 of the storage box 18.
Since the front end of the seat 30 is supported by the storage box 18, the entire seat 30 can be firmly supported. Therefore, even when an occupant is seated on the seat 30, the seat 30 does not deform vertically and the seat bottom plate 31 does not enter into the opening 18a of the storage box 18. storage space is not undesirably reduced.

Moreover, since this storage box 18 is covered by the cover 32, even though there is a large storage box 18 below the seat 30, this storage box 18
is not exposed to the outside. Therefore, the area below the seat 30 is neatly gathered up, and a good appearance can be obtained without giving the impression of a storage space.

Furthermore, the upper end of the shock absorber 15 that suspends the engine unit 10 is connected to the support section 14 that continues to the upper end of the rising section 5, and the bottom plate 19 of the storage box 18 is arranged so as to avoid the upper end of the shock absorber 15. Since the storage box 18 itself is formed deeply and the upper end of the buffer 15 is raised, the length of the buffer 15 can be secured. This makes it possible to increase the swing stroke of the engine unit 10 in the vertical direction, and the ride comfort improves accordingly.

Furthermore, since the rear half 18b of the storage box 18 covers the rear wheel 13 from above while maintaining the box shape, the bottom plate 19 of this storage box functions as a mudguard to prevent mud from splashing upwards onto the rear wheel 13. It will be fulfilled. Therefore, it is possible to prevent mud and the like from adhering to the fuel tank 22 and other items below the seat 30 without providing a special mud guard.

In the above embodiment, the frame member is one piece, but for example, the frame member may be branched into two pieces from the middle of the extension part,
This branching portion may be raised and a storage box may be installed at its upper end.

[Effects of the Invention] According to the present invention described in detail above, since the sheet is attached to the storage box that protrudes above the frame, the size of the storage box and its top opening is not restricted by the shape of the frame. At the same time, brackets for supporting the seat from the frame can be omitted.
Therefore, not only can the frame structure be simplified, but also a large space for installing the storage box can be secured between the seat and the frame.

In addition, since the part that fixes the storage box to the frame does not need to protrude around the storage box, there is no need to create a relief on the peripheral wall when fixing the storage box to the frame, which reduces the capacity of the storage box. and the opening shape can be enlarged.

Therefore, the dimensions of the storage box in the vertical, horizontal, and front-rear directions can be made large, and the capacity of the storage box can be ensured sufficiently to accommodate large items without difficulty.

Furthermore, since the storage box covers the rear wheels from above while maintaining its box shape, this storage box functions as a mudguard to prevent dirt from splashing onto the rear wheels, and the items stored in the storage box can be stored in the storage box. This prevents mud, etc. from adhering to the surface.

Further, since the front end and the intermediate portion of the seat in the longitudinal direction are supported by the storage box having a length extending substantially over the entire length of the seat, the entire seat can be firmly supported. Therefore, even when a passenger is seated on the seat, the seat will not be deformed vertically and the bottom of the seat will not fit into the top opening of the storage box, leaving no space for storage inside the storage box. It does not have to be reduced as desired.

Furthermore, the bottom plate of the storage box protrudes below the connection part between the top end of the shock absorber and the frame, so the position of the top end of the shock absorber can be adjusted while forming the storage box itself deep vertically. By increasing the height, the length of this buffer can be secured. This makes it possible to increase the swing stroke of the engine unit in the vertical direction, and the riding comfort improves accordingly.

In addition, since the storage box is hidden by the cover, a good appearance can be obtained despite the presence of the large storage box below the seat.
