Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a rear body cover and a seat in a motorcycle.

[Prior art and problems to be solved]

Conventionally, in order to fix the upper end of the side cover that covers the lower part of the seat of a motorcycle,
There was something described in the issue.

In the method described in the above publication, the upper protruding part of the side cover is curved so as to straddle the upper part of the seat support frame, a hole is provided in this horizontal part, an elastic piece is fitted into the hole, and the bottom plate of the seat is is mounted on the seat support frame via this elastic piece, and the upper protrusion of the side cover is pressed against the seat support frame by the weight of the driver sitting in the seat, and the upper part of the side cover is pushed by the frictional force. Because it is designed to be fixed,
The pressing force against the seat support frame fluctuated widely due to the vertical vibration of the vehicle body as it traveled, making it impossible to securely fix the upper part of the side cover to prevent it from moving in the width direction of the vehicle body.

In particular, in the case of a rear body cover that covers the lower side surface of the seat, the top surface behind the seat, and both side surfaces below the seat, both front side surface portions tend to deform laterally, making it difficult to adopt the above-mentioned structure.

For this reason, by screwing and fixing the upper sides of both front side surfaces that cover both sides of the lower part of the seat to the upper surface of the seat support frame, we attempted to increase the lateral strength and rigidity of both front side surfaces of the rear body cover. Something was warm.

In such a structure, in order to supplement the strength of such covers made of resin material, it is necessary to increase the thickness of the threaded part, or to use a metal collar on the threaded part.
Or lightweight and high strength polypropylene (PP)
We are adopting methods such as forming covers with

However, when using these methods, a sink mark occurs on the surface of the product in the area where the wall thickness has been increased after molding, impairing the appearance.
The number of parts increases. Covers are appearance parts and require different colors, and are not used as paint materials.
ABS resin is suitable, but if the covers are made of polypropylene, a polypropylene resin coating material must be used, and in addition to the polypropylene material itself being expensive, there is also a pre-painting treatment process. This also causes problems such as a significant increase in production costs.

[Means and actions for solving the problem]

The present invention relates to an improvement of a motorcycle that overcomes these difficulties, and is equipped with a rear body cover that is located below or adjacent to the rear of the seat and covers both sides below the seat, the top surface rearward from the seat, and both sides below the seat. , in a motorcycle with a seat arranged at the rear of the vehicle body, upper edges facing in the width direction of the vehicle body are integrally formed on the upper edges of both front sides of the rear body cover that cover both sides below the seat, and support a pair of left and right seats; The upper side portion and the seat bottom plate are removably connected to each other by a connecting means located inwardly in the width direction from the frame, and an elastic member is provided on the upper surface of the pair of left and right seat support frames over the front and rear range of the seat bottom plate. The present invention is characterized in that it has a structure in which an upper side portion of the rear body cover is placed on the elastic material.

As described above, the present invention integrally forms upper edges facing inward in the width direction of the vehicle body on the upper edges of both front side surfaces of the rear body cover that cover both sides below the seat;
Since the upper side portion and the seat bottom plate are removably connected to each other by the connecting means at a position inward in the width direction from the right pair of seat support frames, the upper side portions of the front both side surfaces of the rear body cover are connected to the connecting means and the seat bottom plate. By being firmly connected to the bottom plate, the lateral strength and rigidity of both front side surfaces can be greatly increased.

Further, in the present invention, an elastic material is attached to the upper surface of the pair of left and right seat support frames over the front and rear range of the seat bottom plate, and the upper side of the rear body cover is placed on the elastic material. The load of the seat and the weight of the driver are transmitted from the upper side of the rear vehicle body cover to the seat support frame via the elastic material, and the concentrated load does not act on the upper side but acts on the rear body cover. The load is reduced, the rear body cover can be formed of an inexpensive material with relatively low strength, and a sense of unity between the seat and the rear body cover is obtained, improving the appearance.

〔Example〕

An embodiment of the present invention shown in FIGS. 1 to 5 will be described below.

FIG. 1 shows a motorcycle 10 as a left side view of the vehicle body, and in the motorcycle 10,
An engine E is disposed between the front and rear wheels FW and RW, and a fuel tank 20 is located above the engine E. The fuel tank 20 is supported by a pair of left and right main frames 12 and is located behind the fuel tank 20. Wow, seat 30
is supported by a pair of left and right seat support frames 14 each having a rectangular cross section. Further, below or adjacent to the rear of the seat 30, a resin rear body cover 40 (integrated side cover and rear cowl) that covers both side surfaces and the top surface of the rear half of the vehicle body is attached to the vehicle body frame.

The fuel tank 20 is secured to the vehicle body frame via anti-vibration rubber (not shown) at a pair of protrusions 24 protruding from the left and right rear ends, and is located at the center in the vehicle width direction. Then, the protruding piece 22 that also protrudes from the rear end is screwed onto the horizontal member 16 attached to connect the left and right seat support frames 14 via the vibration isolating rubber 26. Fixed. A projecting piece 34 extending from the bottom plate 32 at the front end of the seat 30 is removably inserted into the horizontal member 16 from the rear side of the vehicle body.
In addition, a pair of left and right L-shaped protrusions 36 that are vertically installed on the bottom plate 32 at the rear end of the seat 30 are fixed to the flat upper surfaces of the left and right seat support frames 14 by welding. It is removably fitted into the stopper piece 18 from the vehicle body side (see FIGS. 2 and 3).

On the other hand, the rear body cover 40, which is formed in a U-shape as a whole, has two points A and B on one side, and a total of four points on the left and right sides.
It is screwed onto the vehicle body frame, and its bent upper sides 42, 42 are inserted between the seat support frames 14, 14 and the seat 30. The upper side 42,
42 is a rectangular seat support frame 14, 14
The seat 30 is in contact with rubber plates R, R, which are relatively long elastic bodies attached to the flat upper surface of the seat 30, and most of the load of the seat 30 and the driver is carried by the contact relationship between the upper side 42 and the rubber plate R. It is adapted to be transmitted to the support frames 14,14.

Further, the floor plate 32 of the seat 30 and the upper side 42 of the rear body cover 40 are integrally screwed together at a pair of points C and D on the front, rear, left and right sides.
