Description

[Detailed Description of the Invention] The present invention relates to an attachment structure that allows a rear cowl to be easily attached to a rear fender in a small vehicle such as a motorcycle or a tricycle.

Conventionally, the rear cowl of a small vehicle has been fastened to the vehicle body frame directly or via a separate attachment member with bolts or nuts.

However, when using such a fixing means, there are problems such as poor workability during installation and a large number of parts.

The present invention addresses the above-mentioned problem and attaches the rear cowl by fitting a columnar holding piece integrally formed on the side wall of the resin rear fender with a locking jaw piece integrally formed on the side wall of the U-shaped rear cowl. The purpose is to provide a rear cowl attachment structure for a small vehicle that is easy to attach and detach, allows reliable attachment, and requires a small number of parts.

An embodiment of the present invention shown in FIGS. 1 to 11 will be described below.

FIG. 1 schematically shows the rear structure of a motorcycle, in which a rear fender 6, a rear cowl 9, and a seat 5 are arranged on a backstay 1 that is a frame body, and a side rail 2, and a pivot mechanism 4. The rear fork 3 is pivotally supported by known means.

Further, the rear fender 6 is made of resin,
It is formed by a front rear fender 7 and a rear rear fender 8, and the front rear fender 7 is
Locking pieces 7a, 7b, 7c, 7d that engage from the inside of a pair of backstays 1 on both sides of the front curved part.
The engagement groove 11 (inner wall 12, outer wall 14, and groove bottom 1
6) is formed, and a side wall 17 is erected on the upper part of the groove bottom 16, and extends further rearward from the rear part of the engagement groove 11 together with the inner wall 12 and a part of the groove bottom 16 ( an inner wall 12 defining the engagement groove 11;
and a portion of the groove bottom 16 extends rearward beyond the engagement groove 11), and is continuous with the rear wall 19 (the rear wall 19 is connected to both side walls 17 at both sides and rearwardly at the lower end). (continuous with curved part 10)
(See Figures 2 to 5).

Moreover, on the front outer wall surface of the pair of side walls 17, four columnar holding pieces 18 having a groove-shaped cross section are provided in a zigzag arrangement to protrude outward in the width direction of the vehicle.
The groove-shaped bottom wall surface of 8 is the rear cowl 9 described later.
In addition, the tip edge of each columnar holding piece 18 is open and inclined at a predetermined angle from the rear wall 19 side toward the front with respect to the side wall 17, and is tilted downward from above the side wall 17. They are formed to be included in the same plane that opens and slopes at a predetermined angle (therefore, the front part of the columnar holding pieces 18 is longer than the rear part) (Fig. 1). (See Figure 3).

In addition, at predetermined positions on the outer wall 14 and inner wall 12 of the engagement groove 11, there is provided a rear rear fender 8, which will be described later.
At the same time, locking holes 15 and 13 to be screwed onto the side rail 2 are formed.

On the other hand, the rear rear fender 8 has a fixed bracket 20 erected on both sides of the top thereof, and the fixed bracket 20 has an upright portion 21 and a partially block-shaped portion 23.
It is formed with a spacer piece 22 that forms a shape, and locking holes 24 and 25 are formed in the upright portion 21 (hereinafter,
(See Figures 7 and 10).

Thus, the front rear fender 7 is engaged and supported from the inside by the pair of backstays 1 and the side rails 2 by the locking pieces 7a, 7b, 7c, and 7d, and is also fitted into the engagement groove 11. A part of the fixing bracket 20 of the rear rear fender 8 is inserted, and the fixing bracket 20 of the rear rear fender 8 is inserted into the locking hole 15 of the outer wall 14 and the locking hole 2
4, and is fixed to the inner wall of the pair of side rails 2 with bolts and nuts with the locking holes 13 and 25 of the inner wall 12 aligned with each other (see FIGS. 1 and 10). .

Further, the rear cowl 9, which is disposed on the top surface of the rear part of the vehicle body and is attached to the rear fender 6 in a manner that connects to the seat 5 from the rear side of the vehicle body, is formed as a U-shaped body, and is provided at a predetermined distance from the open end of the U-shape. It has a shape bent to one side at the part where it is placed, and has a sled-like shape when viewed from the side, and the top of the sled-shaped side wall 27 has a
A pair of flat plate-shaped locking jaw pieces 28 are provided to protrude, and a fixing bracket 29 having a U-shaped notch is provided to protrude inward from the U-shaped open end (Fig. 8,
(See Figure 9).

Note that the pair of front side walls 26 of the rear cowl 9
is formed into a polygonal cross-sectional shape 30.

Further, a tail light 31 is screwed onto the rear wall 19 of the front rear fender 7.

Since the embodiment shown in FIGS. 1 to 11 is constructed as described above, the rear cowl 9 can be attached to the front rear fender 7 with the opening/closing (or removable) seat 5 open. As shown in FIG. 11, the locking jaws 28 are fitted and locked between the column-shaped holding pieces 18 provided in a zigzag pattern on the side walls 17, and the pair By screwing the fixing bracket 29 onto the bracket 1a protruding from a predetermined position of the back stay 1, the rear cowl 9 is reliably positioned and fixed.

Thereafter, the seat 5 is placed and fixed on the side rail 2 to complete the assembly.

In the embodiment described above, the rear cowl 9 can be attached simply by fitting and locking the locking jaws 28 of the rear cowl 9 between the columnar holding pieces 18 protruding from both side walls 17 of the front rear fender 7. This can be done easily and quickly, and the positioning accuracy is high.

Furthermore, in the embodiment described above, since the columnar holding piece 18 for attaching the rear cowl 9 is integrally molded with the front rear fender 7, the number of parts is small, which can contribute to improving productivity.

Furthermore, in the embodiment, since the rear wall 19 for attaching the tail light 31 is integrally molded on the front rear fender 7, the attachment accuracy of the tail light 31 is improved, and the positional relationship with the rear cowl 9 or the rear rear fender 8 is improved. is accurate and improves appearance.

Furthermore, since the tail light 31 and the rear cowl 9 can be attached to the front rear fender 7 before the front rear fender 7 is assembled to the vehicle body, work efficiency is improved.

Furthermore, both side walls 1 of the front rear fender 7
7. The space formed by the rear curved portion 10 and the rear cowl 9 can be used as an article storage room.

In the embodiment, the front rear fender 7
Although both side walls 17 having columnar holding pieces 18 and a rear wall 19 for attaching the tail light 31 are provided in the rear rear fender 8, substantially the same effects can be obtained even if such pieces are provided in the rear rear fender 8. Can be done.

As is clear from the above explanation, the resin rear fender has a pair of opposing side walls that are integrally installed on the left and right sides of the resin rear fender. A mode in which a plurality of pillar-shaped holding pieces are integrally provided, and a rear cowl having a pair of flat plate-shaped locking jaw pieces formed inwardly protruding from the left and right side walls is pushed down from the rear side of the vehicle body toward the front of the vehicle body. The rear cowl is made up of a plurality of column-shaped holding pieces that are removably inserted into and locked between the plurality of column-shaped holding pieces.
In a form that hugs the left and right side walls of the rear fender,
A rear cowl attachment structure was proposed that is characterized by being attached to the rear fender.

According to such a configuration, the rear cowl can be attached easily and quickly, and the positioning accuracy is also high.

Furthermore, since the columnar holding piece for attaching the rear cowl is integrally molded with the rear fender, the number of parts is reduced, which can contribute to improved productivity.
