Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alignment structure for a side cover for a two-wheeled or three-wheeled motorcycle.

In recent years, in order to improve the external appearance of motorcycles and increase their quality, the fuel tank is located approximately on the side of the middle part of the vehicle body and below the seat, and the connecting edge is connected to the connecting edge of the fuel tank. A side cover made of synthetic resin may be provided so as to form a continuous surface with the side surface of the tank.

This side cover is generally attached by locking the locking protrusions provided at three locations on the back side of the side cover to locking portions (grommets) provided on the connecting edge of the fuel tank and the vehicle body frame, respectively. It is something. In particular, in order to simplify the configuration, if the number of protrusions on the back of the side cover is reduced to the minimum necessary, for example, three, at the connecting edge of the fuel tank, one protrusion protruding approximately in the middle of the connecting edge of the side cover will be used. It is something that is locked. For this reason, if there is a slight error (several m/m) in the surface position of the protrusion on the side cover with respect to the axis, the connecting edge of the side cover will not be on a uniform surface with the connecting edge of the fuel tank when installed, resulting in a step. There is a problem in that it spoils the appearance.

By the way, since the side cover is made of synthetic resin, it is inevitable that it will be deformed by several m/m when it is cooled after being molded.

For this reason, in the past, a side cover was made as a prototype, and the prototype was repeated many times while matching the actual product.
In the middle of the process, reinforcing ribs are installed to prevent deformation in places where deformation is likely to occur on the back side of the side cover, or a correction mold is installed separately from the molding mold to correct deformation. The deformation of the side cover was corrected so that the connecting edge of the side cover was flush with the connecting edge of the fuel tank.

Therefore, it takes a lot of time and effort to go from prototype to commercialization, and there are problems such as the need for extra equipment for correction.

This invention was created in view of the above circumstances, and aims to eliminate the need for correction work and reinforcing ribs to prevent deformation, and to reduce the time and effort required from prototype to commercialization. In order to achieve this purpose, it is located on the side of the approximately middle part of the vehicle body and under the seat, and is arranged so that its connecting edge can be connected to the connecting edge of the fuel tank to form a continuous surface with the side surface of the fuel tank. In the side cover for a motorcycle, a predetermined portion of a member that overlaps with the outer surface of the side cover body near the connection edge when attached to the vehicle body or near the connection edge of the side cover body; A protrusion for correcting the surface position of the side cover body is provided in a protruding manner, and when the vicinity of the connecting edge of the side cover body or a predetermined location of the member abuts against the protrusion, the side cover body is moved in the thickness direction of the side cover body. For a motorcycle, the side cover body is configured such that a pressing force can be applied thereto, and the connecting edge of the side cover body is in a uniform plane with the connecting edge of the fuel tank. This provides a positioning structure for the side cover.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a two-wheeled motorcycle 2 equipped with a side cover 1 to which the present invention is applied. It is located on the side and is arranged so that the connecting edge 1a can be connected to the connecting edge 5a of the fuel tank 5 to form a continuous surface with the side surface of the fuel tank 5.

The side cover 1 is made of synthetic resin, and as shown in FIGS. 3 to 5, an extending edge portion 1c (the sheet 4
A plurality (for example, three) of projections 6 for surface position correction are integrally provided on the end surface of the connection edge 1a (the edge overlapping the back side of the lower edge 4a). When the back surface of the lower edge 4a of the sheet 4 comes into contact with these protrusions 6 as shown in FIG. 8, a pressing force is applied to the side cover main body 1b in the thickness direction (in the direction of the arrow in FIG. 8). The pressing force causes the connecting edge 1a of the side cover main body 1b to be flush with the connecting edge 5a of the fuel tank 5.

located on the back surface side of the side cover main body 1b and approximately in the middle of the connecting edge 1a thereof, and the connecting edge 1
First and second locking protrusions 7 and 8 are protruded from substantially the middle of the edge 1d opposite to a. Further, a third locking protrusion 9 is provided protrudingly below approximately the middle on the back side of the side cover main body 1b.

The first and second locking protrusions 7 and 8 are approximately warhead-shaped and have the same construction, and are provided in a protruding manner on a pedestal 10 formed protrudingly from the back surface of the side cover main body 1b for reinforcement purposes. . The third locking protrusion 9 has a tongue shape and has a through hole 11 in the center.
have. The first locking projection 7 is a lock formed by a grommet provided on an extending edge 5b extending along the connecting edge 5a of the fuel tank (5), as shown in FIGS. 2 and 9. 12 and the second locking protrusion 8 are respectively fitted and locked to locking portions (not shown) made of grommets provided at predetermined locations on the vehicle body frame 3a. Furthermore, a third locking protrusion 9
is locked to a locking portion (not shown) provided at a predetermined location on the vehicle body frame 3a.

Note that 13 in FIGS. 7 and 8 is the bottom plate of the seat 4.

Therefore, in the present invention, a side cover 1 having protrusions 6 for correcting the surface position is manufactured as a prototype, and the side cover 1 is attached to a latching part with the latching protrusions 7, 8, 9 provided on the fuel tank 5. 12 and the locking portions provided on the vehicle body frame 3a, the seat 4 is attached and the back side of the lower edge 4a is attached to the side cover 1.
The protrusion 6 is brought into contact with the back surface of the lower edge 4a of the sheet 4 by overlapping with the upper extending edge 1c. In this state, it is checked whether the connecting edge 5a of the fuel tank 5 and the connecting edge 1a of the side cover 1 form a uniform surface, and the height of the protrusion 6 is corrected so as to form a uniform surface.

The mold portion of the protrusion 6 of the molding die may be modified in accordance with this modification.

In the above embodiment, the side cover main body 1b
Although the surface position correction protrusion 6 is provided on the side cover body 1b, the connection edge 1 of the side cover body 1b is not limited to this.
The surface position correction protrusion 6 may be provided at a predetermined location of a member, for example, the sheet 4, which overlaps at a predetermined location on the outer surface near a. Further, the shape and number of the surface position correction protrusions 6 are not limited to those in the above-mentioned embodiments. Furthermore, it goes without saying that other configurations may be modified in various ways without departing from the gist of the present invention.

As mentioned above, the positioning structure of the motorcycle side cover of the present invention is located on the side of the approximately middle part of the vehicle body and below the seat, and connects the connecting edge to the connecting edge of the fuel tank. In a motorcycle side cover disposed so as to form a continuous surface with the side surface, a predetermined portion is provided near the connecting edge of the side cover main body, or on the outer surface of the side cover main body near the connecting edge when attached to the vehicle body. A protrusion for correcting the surface position of the side cover main body is provided protrudingly at the predetermined location of the member where the parts overlap, and when the vicinity of the connection edge of the side cover main body or the predetermined location of the member abuts the protrusion, A pressing force is applied to the side cover main body in the thickness direction thereof, and the pressing force causes the side cover main body to have its connecting edge flush with the connecting edge of the fuel tank. This feature eliminates the need for straightening work and reinforcing ribs to prevent deformation, and also eliminates the need for equipment for that purpose.Also, corrections at the time of trial production are easy and reliable, and therefore, from prototype to commercialization. It is possible to reduce the time required.
