BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body cover mounting structure for a scooter-type motorcycle for mounting a body cover that covers the area from the bottom of the seat to the left and right sides of the footboard.

0002

[Prior Art] In a scooter type motorcycle, a side cover surrounds the lower part of the seat, and left and right side molding covers cover the area from the lower left and right side of the side cover to the left and right sides of the footboard. There is. Conventionally, as a mounting structure for such a vehicle body cover, for example, the above-mentioned side cover is bolted and fixed to the vehicle body frame, and the above-mentioned side molding cover is formed with locking holes in the side cover and footboard, and the above-mentioned side molding cover is fixed to the vehicle body frame by bolting. A locking pawl is provided protrudingly for locking in the locking hole. When installing the side molding cover, first place the side molding cover in the pre-installation position and align the locking pawl with the locking hole.In this state, insert the locking pawl into the locking hole in the vehicle width direction. Then, slide the side molding cover to the installation position in the longitudinal direction of the vehicle to lock the locking pawl to the edge of the locking hole, and finally connect the side molding cover, side cover, and footboard. Secure with bolts.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned conventional vehicle body cover mounting structure, since the side molding cover is long, the above-mentioned locking claws and locking holes are large in number and spread over a wide range in the front and rear direction. It will be located at Therefore, it is difficult to simultaneously align all of the locking pawls with the locking holes, and therefore there is a problem in that the workability of inserting the locking pawls into the locking holes, that is, the workability of attaching the locking pawls is low. Here, in order to simplify the above positioning work, for example, for the rear half of the side molding cover, a so-called sliding method is used in which the two are locked by inserting a locking pawl into the locking hole and sliding it. For this purpose, it is conceivable to adopt a so-called push-in method in which the side molding cover is placed in the mounting position and then pushed in the vehicle width direction to lock the locking pawl in the locking hole. However, if the above-mentioned simple push-in method is adopted, there is a concern that the locking claws may be damaged when the side molding cover is removed. The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a body cover mounting structure for a scooter type motorcycle that has high mounting workability and can avoid the problem of damage to the locking pawl.

0004

[Means for Solving the Problems] The present invention surrounds the lower part of the seat with a side cover, and extends from the lower left and right side of the side cover to the left and right sides of the footboard with left and right side molding covers. In the vehicle body cover mounting structure for a scooter-type motorcycle, a first locking hole is formed in either one of the rear part of the side molding cover and the side cover, and the side molding cover is positioned in the position before installation in the other side. a first lock that can be inserted into the first locking hole when the side molding cover is mounted, and that locks onto an edge of the first locking hole when the side molding cover is slid in the longitudinal direction of the vehicle to the mounting position; By forming a claw, forming a second locking hole in either the front part of the side molding cover or the footboard, and placing the side molding cover in the mounting position on the other side and pushing it in the vehicle width direction. The present invention is characterized in that a second locking pawl is formed that locks on the edge of the second locking hole and releases the locking when the side molding cover is slid to the pre-installation position.

[0005]

[Operation] To install the side molding cover in the vehicle body cover mounting structure of the present invention, first, position the rear part of the side molding cover to the pre-installation position and align the first locking pawl and the first locking hole. After inserting the first locking pawl into the first locking hole, if the first locking pawl is slid in the longitudinal direction of the vehicle to the mounting position, the first locking pawl is thereby locked to the edge of the first locking hole. I will do it. Next, if you push the front part of the side molding cover near the second locking claw in the vehicle width direction, this will cause the second
The locking pawl will lock on the edge of the second locking hole. On the other hand, when removing the side molding cover, first slide the entire side molding cover to the pre-installation position. Then, the locking between the first locking pawl and the first locking hole is released, and the locking between the second locking pawl and the second locking hole is also released,
It can be removed as is. In this way, in the present invention, the sliding method is adopted for the rear half of the side molding cover, and the push-in method is adopted for the front half, so when installing, first align the locking claws and the locking holes on the rear half only. The assemblability can be improved by eliminating the need to align the entire long side molding cover at once as in the conventional structure described above. In addition, when removing the side molding, by sliding the entire side molding, the locking pawl and the locking hole can be easily released from the locking pawl of the front half using the above-mentioned push-in method, thereby avoiding damage to the locking pawl.

Embodiments Hereinafter, embodiments of the present invention will be explained with reference to the drawings. 1 to 5 are diagrams for explaining a body cover mounting structure for a scooter-type motorcycle according to an embodiment of the present invention. FIG. 1 is a side view of the structure of this embodiment, and FIG. 2 is an enlarged side view of the main parts. 3 is a partially sectional side view of the rear end of the vehicle, FIG. 4 is a plan view of a fuel intake port, and FIG. 5 is a left side view of a scooter type motorcycle equipped with the structure of the embodiment. .

In the figure, reference numeral 1 indicates a scooter-type motorcycle in which the structure of this embodiment is adopted, and a body frame 2 of this
is the so-called underbone type, and the head pipe 2
The upper end of the main frame 2b, which is approximately L-shaped in side view, is connected to a, and the front ends of the pair of left and right side frames 2c are connected to the lower end of the main frame 2b, and the side frames 2c are raised upward and further rearward. It has an extended structure.

The head pipe 2a connects the front wheel 3 at the lower end.
A front fork 4 is pivotally supported so as to be steerable left and right, and a handlebar 5 is fixed to the upper end of the front fork 4. Further, a footboard 14 is mounted at the connection between the side frame 2c and the main frame 2b, thereby forming a low-floor footrest 15. The footboard 14 is made up of a flat part 41 and a rising part 42 that rises upwards.
A and rear boss 41b are fastened to front bracket 36 and rear bracket 37 with bolts 38a and 38b, respectively. Note that the front and rear brackets 36 and 37 are welded and fixed to the connecting portion between the main frame 2b and the side frame 2c.

A unit swing type engine unit 6 is disposed behind the footrest 15, and is suspended and supported near the rear bending portion of the side frame 2c so as to be swingable up and down. Further, above the engine unit 6 is a storage box 9, and behind this is a fuel tank 1.
0 are arranged respectively, and the upper opening of the storage box 9 can be opened and closed by a seat 8 arranged above it.

The fuel tank 10 includes a front tank 10a.
The flange of the rear tank 10b is welded to each other, and the upper edge of the flange is bolted to the portal bracket 50, and the lower edge is bolted to the rear bracket 69. The gate-shaped bracket 50 is a gate-shaped bracket installed between the left and right side frames 2c, and the rear bracket 69 extends rearward from the rear end of the side frame 2c. Further, a fuel supply pipe 10c is welded and fixed to the upper wall of the rear tank 10b, and a fuel supply cap 70 is fitted into the upper opening of the pipe 10c. The oil supply pipe 10c extends inward from the upper wall surface of the rear tank 10b, and a pair of air vent holes 10d, 10d are formed in the extending portion inside the tank. These air vent holes 10d, 10d are opposed to each other across a center point B at a position of 45 degrees clockwise with respect to the vehicle center line A, as shown in FIG. 4 when viewed from above.

The reason why the oil supply pipe 10c is extended inward to the tank is to know when the amount of oil supply has reached the possible amount. That is, when the refueling surface reaches the lower surface of the refueling pipe 10c, the fuel rises within the pipe 10c and is visible from the outside, so that the refueling person can know that the refueling amount has reached the limit. Further, when the oil level is higher than the lower surface of the oil supply pipe 10c and the air in the tank expands due to a rise in temperature, the air will escape from the air vent hole 10d to the outside through the air vent hole of the fuel filler cap 70. The pressure inside the tank can be maintained at atmospheric pressure.

The reason for providing a pair of air vent holes 10d and arranging them facing each other is to improve the ease of assembling the oil supply pipe 10c and to increase the effective tank capacity. That is, the air vent hole 10d needs to be located at a predetermined position relative to the vehicle inclination. Therefore, when there is only one air vent hole 10d, when welding the fuel pipe 10c to the tank, it is necessary to control the assembly angle position of the pipe 10c, such as by positioning the notch 10e for the fuel cap 70 on the front side. As a result, assembly work efficiency decreases. However, if there is one pair of air vent holes 10d, there is no problem even if the notch 10e is located on the rear side and the notch 10f is located on the front side.In other words, the above-mentioned management is unnecessary, and the assembly workability is improved accordingly.

In order to ensure the above-mentioned air vent, it is necessary to avoid the problem that the air vent hole 10d is clogged with fuel due to the inclination of the vehicle, etc.
It is necessary to increase the inward protrusion length of 0c, but this will reduce the effective capacity of the tank. On the other hand, if a pair of air vent holes 10d are provided as described above, the possibility of blockage of the air vent holes due to tilting of the vehicle is reduced, and therefore there is no need to make the fuel supply pipe 10c very long, increasing the effective capacity accordingly. can.

A carrier bracket 71 is bolted and fixed to the rear bracket 69. The carrier bracket 71 has a shape that extends upward along the rear wall of the fuel tank 10, and a mounting boss 71a is fixed to the upper end of the bracket 71. This mounting boss 7
1a protrudes outward from a lead-out hole 72a formed in the case of the tail light 72, and the carrier 51 is attached to the mounting boss 71a.
The front end of the stay portion 51b is fixed with bolts. Here, the mounting boss 71a also functions as a temporary mounting member when attaching the taillight 72. The front end of the main body portion 51a of the carrier 51 is fastened together with the rear flange portion 58 of the storage box 9 by bolts 50a planted on the upper surface of the portal bracket 50.

The front part of the motorcycle 1, that is, the part in front of the footrest 15, is surrounded by a front cover 13, and the rear part, that is, the lower peripheral part of the seat 8, is surrounded by a side cover 11, a pair of left and right sides. It is surrounded by the rear part of the side molding cover 12 and the raised part 42 of the footboard 14. Further, the footrest portion 15 is surrounded by the flat portion 41 of the footboard 14 and the front portion of the side molding cover 12.

The side cover 11 is an annular member surrounding the lower part of the seat 8, and its rear edge is bolted to the rear edge of the storage box 9, and its front edge is attached to the footboard 14. It is bolted and fixed to the rising part 42 of the. In addition, the side molding cover 12 is
The side cover 11, the raised part 42 of the footboard 14, and the flat part 41 are long and large, and the rear part 12a corresponding to the side cover 11 part and the footboard 14 are large and long. First half 1 corresponding to
2b.

The rear half 12 of the side molding cover 12
A joint piece 12c that abuts the lower edge 11a of the side cover 11 is bent inward and formed on the upper edge of the side cover 11,
The inner end of the joint piece 12c is further bent upward. The joint piece 12c has two first locking holes 1.
2d are formed at intervals in the front and rear. Furthermore, a substantially L-shaped first locking pawl 11b is formed on the lower edge 11a of the side cover 11 to protrude downward. The first locking claw 1
1b is inserted into the first locking hole 12d, and its lower side portion 11d extending rearward is locked to the rear edge of the first locking hole 12d. Further, a positioning piece 11c is formed to protrude downward between the front and rear first locking claws 11b, 11b of the lower edge 11a of the side cover 11,
This is in contact with the inner surface of the upper edge of the side molding cover 12.

Further, a band-shaped joint piece 14b is formed in a portion of the footboard 14 corresponding to the front half 12b of the side molding cover 12 so as to protrude downward from the lower edge 14a of the footboard 14. This joint piece 14b
Four second locking holes 14c are formed at intervals in the front-rear direction. This second locking hole 14c has a hook shape in which the vertical width of the front part is narrower than that of the rear part, and the upper edge 14c of the front part
A locking protrusion 12f of the second locking pawl 12e is locked to d. Here, the vertical width of the rear portion of the second locking hole 14c is set to be larger than the vertical thickness of the locking protrusion 12f. Further, the second locking pawl 12e is integrally formed on the upper edge of the front half portion 12b of the side molding cover 12 so as to protrude inward.

Next, the effects of this embodiment will be explained. In the structure of this embodiment, in order to attach the side molding cover 12, first the side molding cover 12 is fitted so that the entire first locking claw 11b of the side cover 11 fits into the first locking hole 12d of the rear half 12a of the side molding cover 12. In this state, raise the side molding cover 12 a little to open the first side molding cover 12.
Insert the first locking claw 11b into the locking hole 12d (see Fig. 1(a)
), then slide the side molding 12 forward. Then, the lower side 1 of the first locking claw 11b
1d is locked to the inner surface of the rear edge of the first locking pawl. In this case, it is not necessary to align the locking claws and the locking holes for the front half 12b of the side molding cover 12.

Due to the above sliding, the second locking pawl 12e of the front half 12b of the side molding cover 12 is located in front of the second locking hole 14c of the footboard 14, and in this state, the front half 12b strongly push in the vicinity of the second locking pawl 12e in the vehicle width direction. Then, the second locking pawl 12e is inserted into the front part of the second locking hole 14c while elastically deforming the upper edge 14d, and the locking protrusion 12f locks on the inner surface of the upper edge 14d. After that, tighten and secure the necessary parts with bolts.

As described above, according to the vehicle body cover mounting structure according to this embodiment, the rear part 12a of the side molding cover 12
The slide method was used for mounting the front half part 12b, and the push-in method was adopted for mounting the front half part 12b, so when installing, first align only the first locking claw 11b and the first locking hole 12d of the rear half part 12a. Therefore, the ease of assembly can be improved accordingly.

In addition, when removing the front part 12b using the push-in method, the second locking claw 1 is removed by sliding the entire side molding cover 12.
2e and the second locking hole 14c can be easily released, and therefore damage to the second locking pawl 12e can be avoided.

Furthermore, in this embodiment, the second locking hole 14c
The front part is narrower in vertical width than the rear part, and the locking protrusion 12f of the second locking pawl 12e is locked to the upper edge 14d of the front part. Therefore, the upper edge 14d to which the locking protrusion 12f is to be locked has an elongated shape in the front-rear direction.
Therefore, dimensional errors in the longitudinal length of the side molding cover 12 can be absorbed. Further, the rear portion of the upper edge 14d is opened by the rear part of the second locking hole 14c, so that it is easily deformed elastically when the second locking pawl 12e is pushed in.
Also from this point of view, ease of assembly is improved, and damage to the claws can be avoided.

Furthermore, in this embodiment, since the pushing method is adopted for the front half, the relatively large load at the time of pushing is received by the footboard 14, which has high rigidity to begin with, and the load at the time of pushing is applied to the opposing member. You can avoid deformation.

Furthermore, in this embodiment, the side molding cover 12 is set large so that its height dimension is approximately the same as that of the side cover 11, so by removing this large side molding cover 11, the battery,
Inspection and maintenance of vaporizers, etc. can be easily performed. Also,
The area of the side cover 11 is relatively small, and the area to be painted when painting the side cover 11 can be small.

Note that in the above embodiment, the first locking claw 11b
, first locking holes 12d are formed in the side cover 11 and side molding cover 12, respectively, and second locking claws 12e,
The second locking hole 14c is connected to the side molding cover 12,
Although it is formed on the footboard 14, it may be formed in the opposite way, or it may be slid forward and locked, or conversely, it may be slid rearward and locked.
