Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a part mounting stay that is integrated with a mounting stay located below the rear cowl to attach a taillight that is inserted into the rear hole of a rear cowl that covers the rear of the seat of a motorcycle. This article relates to the rear structure of a motorcycle attached to a motorcycle.

2. Prior Art A tail light attached to the rear of a motorcycle is disclosed in Japanese Patent Application Laid-open No. 56-8778, as shown in FIGS. 7 and 8.

In the conventional one shown in FIGS. 7 and 8, a pair of protruding pieces 02 are provided protrudingly provided inside the rear part of a rear stay 01 that is curved in a U-shape.
Attachment member 03 whose side surface shape is approximately a right triangle
is fixed with bolts 04, and a tail light 06 is attached to this attachment member 03 via vibration-proofing rubber 05.

Problems that the invention aims to solve In the conventional rear structure of motorcycles,
Since the rear stay 01 is attached to the lower part of the rear of the seat, and the mounting member 03 is also exposed, the side surface shape of the rear part of the vehicle body is complicated, and the appearance of the rear part of the vehicle body is not sophisticated.

Moreover, since the rear stay 01 to which this force is applied when doing work such as pulling up the vehicle body is simply curved in a U-shape, this force applies the force to the rear stay 01.
is easily elastically deformed, and the protruding piece 02 and the mounting member 03
Unreasonable stress is applied to the connecting part with the mounting member 0.
There is a risk that the rear stay 01 may fall off, and in order to avoid this, it is necessary to sufficiently withstand the force mentioned above.
This is disadvantageous in terms of weight reduction.

Furthermore, since the rear stay 01 is simply curved in a U-shape, the spacing accuracy between the two pairs of protruding pieces 02 is low.
The attachment member 03 may not be easily assembled to the protruding piece 02 in some cases.

Means and Effects for Solving the Problems The present invention relates to an improvement of the rear structure of a motorcycle that overcomes these difficulties, and includes a rear cowl that covers the lower part of the rear of the motorcycle seat, and a tail that is inserted into the rear hole of the rear cowl. The rear part of the vehicle body is formed by the light and a mounting stay which is curved in a U-shape and extends in a substantially horizontal direction so as to surround the rear cowl from both left and right sides of the rear cowl and is integrally attached to the vehicle body frame. , a component mounting stay is integrally fixed to the inside of the U-shaped curved part and the rear of both side parts of the mounting stay, the tail light is mounted on the component mounting stay, and the rear cowl is attached to both sides of the mounting stay. When installed, the rear cowl covers the rear lower part of the motorcycle body and forms a smooth curved surface, giving it a smart appearance.

In addition, in the present invention, since the component mounting stay is integrally fixed to the inside of the U-shaped curved part of the mounting stay and the rear of both side parts, the mounting stay can be reinforced, and the mounting stay can be made thinner to reduce the weight of the vehicle body. be able to.

Further, in the present invention, since the rear cowl and the taillight are respectively attached to the mounting stay, the error in attaching the taillight to the rear cowl is small, and the accuracy of assembling the taillight can be greatly improved.

Embodiment Hereinafter, an embodiment of the present invention illustrated in FIGS. 1 to 6 will be described. Reference numeral 1 denotes a pair of left and right rear frames of a vehicle body frame, and the rear frames 1 are integrally connected to each other by a cross member 2. The seats 3 are connected to each other, and a seat 3 is placed on the cross member 2.

Furthermore, brackets 4 are integrally provided at four locations on the left, right, front, and rear of the rear frame 1 so as to project downward, and a female thread sleeve 5 is integrally attached to the outer surface of the bracket 4.

Furthermore, the mounting stay 6 made of extruded aluminum with a dovetail groove 7 formed in the center has a circular recess 8.
and a hole 9 are provided, and the mounting stay 6 passes through the recess 8 and the hole 9 and attaches to the female thread sleeve 5.
It is designed to be removably attached to the rear frame 1 via the bracket 4 by means of screws 10 screwed into the rear frame 1.

Furthermore, in the dovetail groove 8 of the mounting stay 6,
A decorative rubber 11 having a cutout circular cross section is fitted.

Moreover, a tail lamp mounting plate 12, which is a component mounting member, is located inside the curved part of the mounting stay 6.
is integrally provided, and a mounting hole 1 is provided in the same plate 12.
Two pieces of 3 are formed symmetrically.

Further, the mounting stay 6 is provided with female threads 14 at two places on the left and right sides, and a hole 17 is provided in a bracket 16 of a rear cowl 15 formed to cover the rear lower part of the seat 3. A bolt 19 is screwed onto the female thread 14. Note that 20 is a washer.

Further, the rear cowl 15 is formed with two rear grip mounting holes 18 on the left and right sides, and a stay 21 is integrally provided in the rear frame 1 so as to be located inside the rear grip mounting holes 18. Hole 18
The boss 22 is integrally attached to the stay 21 with a nut 23 so that the boss 22 is loosely fitted to the rear grip 24 made of an extruded aluminum material and provided with a dovetail groove 25 like the mounting stay 6.
The rear grip 24 is attached to and detached from the rear frame 1 via the stay 21 by a screw 29 which is curved in an inverted U shape and is screwed onto the boss 22 through a recess 26 and a hole 27 provided in the rear grip 24. It is designed to be worn freely. It should be noted that a decorative rubber 28 is fitted into the dovetail groove 25 of the rear grip 24 as well as the mounting stay 6.

Furthermore, the tail lamp mounting plate 1
A rubber bushing 30 is fitted into the mounting hole 13 of No. 2, and a protrusion 32 of a tail light 31 is fitted into the rubber bushing 30.

Since the illustrated embodiment is constructed as described above, after the mounting stay 6 is mounted on the rear frame 1, the rear cowl 15 and tail light 31 are mounted on the mounting stay 6, and the rear grip 24 is attached via the stay 21. By attaching it to the rear frame 1, the rear body portion of a motorcycle can be easily attached.

In addition, the rear cowl 15 and the tail light 3
Since the mounting stay 6 is attached to the rear frame 1, the assembly accuracy and ease of assembly between these parts are improved.

Furthermore, since the mounting stay 6 has sufficient rigidity and strength, it can serve as a side grip.

Furthermore, since the mounting stay 6 and the rear grip 24 are made of extruded aluminum, the cross-sectional shapes of the mounting stay 6 and the rear grip 24 can be freely set to the optimum shape. can be mass-produced at low cost.

Moreover, since the dovetail grooves 7, 25 are formed on the mounting stay 6 and the rear grip 24, the decorative rubbers 11, 28 can be mounted on the mounting stay 6 and the rear grip 24 without using mounting hardware such as screws. Since decorative rubbers 11 and 28 are attached to the mounting stay 6 and rear grip 24, which also serve as side grips, these mounting stays 6,
The rear grip 24 can be firmly gripped without slipping.

Effects of the Invention As described above, with the present invention, the rear part of the vehicle body can be formed to have a sophisticated appearance, and the mounting stays can be reinforced with component mounting stays, thereby making it possible to reduce the weight of the vehicle body.

In addition, in this invention, the tail light inserted through the hole in the rear cowl is attached to the component mounting stay fixed to the inside of the U-shaped mounting stay, so only the rear surface of the tail light is exposed. Lights can be easily attached to the vehicle body.

Further, in the present invention, since the rear cowl and the taillight are respectively attached to the mounting stay, the error in attaching the taillight to the rear cowl is small, and the accuracy of assembling the taillight can be greatly improved.

Moreover, with this invention, the force applied to the mounting stay is borne by the component mounting stay, and the taillight can be firmly held on the vehicle body without having the influence of elastic deformation of the mounting stay spread to the taillight mounting part. .
