Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tail lamp mounting structure for a straddle-type vehicle (such as a buggy) for use on rough terrain.

(Prior art) Conventionally, in straddle-type vehicles for driving on rough terrain,
The tail lamp is attached to the vertical surface of the rear end of the rear wheel fender (see Figure 1). and,
As shown in Fig. 4, its mounting structure is similar to that of general motorcycles, where a lamp housing b and a board c are attached to a tail lamp a, and a lamp housing b and a board c are attached to a fender d.
It was fixed to the fender d by being bolted into a bolt hole f drilled in a recess e of the fender d.

(Problem to be solved by the invention) However, the vehicle targeted by the invention is a straddle-type vehicle for rough terrain, which is intended for driving on rough roads with many bumps and wetlands, and the impact on the road surface during driving. The vibration of the vehicle body caused by the above-mentioned conventional tail lamp mounting structure is quite large, and as the vibration is directly transmitted to the tail lamp mounting part, there are concerns about the durability of the tail lamp. It was necessary to improve the durability.

Furthermore, in order to ensure a good appearance around the location where the tail lamp is disposed, it is necessary to place a damper that acts as a vibration damper in a position that is less visible than the external surface of the tail lamp lens and fender.

Furthermore, as an example of a device for attaching a tail lamp to a fender, there is a device in which a convex portion is provided above the back of the rear wheel fender, and a tail lamp is provided within the convex portion (see Utility Model Application Publication No. 52-53681). Although there are many examples disclosed in the above-mentioned prior art, the present invention has the external appearance described in the prior art (see Figs. 1 and 2) and also has a vibration-proof, strong, and simple mounting structure for the tail lamp. However, there were still areas for improvement.

(Means for Solving the Problems) In view of the above, the present invention has been developed by attaching the tail lamp to a highly rigid part of the vehicle body via a damper made of an elastic material, and by setting the damper in a position that is difficult to see. I made sure to secure it well.
Specifically, the vehicle is assumed to be a straddle-type vehicle for rough terrain that has a bar handle for controlling the front two wheels, a straddle-type seat, and steps arranged on the left and right below the straddle-type seat. . A recess is formed in the rear end surface of the rear wheel fender, and the tail lamp is accommodated in the recess. And the tail lamp,
The lamp housing includes a lamp housing and a lens disposed on the rear side of the lamp housing. The front surface of the edging portion is set at a position facing the bottom surface of the recessed portion with a predetermined distance therebetween. Further, a front surface near the edge of the lamp housing is formed as a damper abutting surface, and a damper is disposed between the damper abutting surface and the recess. The damper is provided with a locking portion formed at one end of the damper, which contacts the damper contacting surface of the lamp housing and is locked to the lamp housing, and a locking portion formed at the other end of the damper on the bottom surface of the recess. A truncated conical fender engaging portion is formed to be inserted and fitted into the locking hole. Furthermore, a damper body is integrally formed between the locking part and the fender engaging part of the damper, and a hollow part is provided inside the damper body for setting an elastic supporting force for the rear wheel fender of the tail lamp. It is structured like this.

(Function) With the above configuration, in the present invention, the damper is disposed between the damper contacting surface of the lamp housing and the recess of the rear wheel fender, so the tail lamp is supported by the rear wheel fender via the damper. As a result, vibrations from the vehicle body are absorbed by the damper.
Since the light is attenuated, the durability of the tail lamp is greatly improved. Furthermore, the damper is attached to the rear wheel fender in a recess formed in the rear wheel fender, and since this recess is a highly rigid portion, sufficient support rigidity for the tail lamp is ensured. Further, the size of the hollow portion formed in the damper main body of the damper can be set arbitrarily, and thereby the elastic supporting force of the tail lamp to the rear wheel fender can be set freely. Furthermore, the damper is arranged between the damper abutting surface of the lamp housing and the recess of the rear wheel fender, so that it is not visible from the outside. A good appearance is ensured around the installation location.

(Example) Next, an example of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a straddle-type vehicle 1 for rough terrain has front wheels 2 and rear wheels 3 arranged at the front and rear of the vehicle body covered by fenders 2a and 3a, respectively, and a tail lamp at the rear end of the rear wheel fender 3a. 4 is installed,
A well-known vehicle (generally a four-wheeled buggy) that is configured with a bar handle 5 for steering the front wheels 2, a straddle-type seat 6, and left and right steps (not shown) as main parts.
It is.

Each of the fenders 2a, 3a is made of plastic, and the left and right sides of the front and rear parts are integrally injection molded. In particular, a recess 3 is formed on the vertical surface 3b at the rear end of the rear wheel fender 3a as shown in FIGS. 2 and 3.
c is formed, and the tail lamp 4 is mounted in the recess 3c.
is installed. The tail lamp 4 includes a lens 7, a bulb (light bulb) 8, a lamp housing 9, a substrate 10, and a damper 11. The lens 7 is a flat plate-shaped translucent member made of plastic and serves as a light emitting surface of the tail lamp 4. Attachment screw insertion holes 7a are provided near both left and right ends. The lamp housing 9 is a bowl-shaped member with a curved recess 9a formed in the center, and a bulb mounting portion 9b into which the bulb 8 is inserted.
is provided, and lead wires 9c, 9c extending toward the vehicle body are connected to the valve mounting portion 9b. Further, a border portion 3f is formed near both left and right ends of the lamp housing 9, and a mounting screw insertion hole 9d similar to that of the lens 7 is formed in the border portion 3f.
is bored, and the rear surface side of this edging portion 3f serves as a receiving seat for the lens 7. Furthermore, the substrate 1
0 is a plate material having a shape that matches the outer shape of the tail lamp 4, and is open at a portion corresponding to the recess 9a of the lamp housing 9, and near both left and right ends correspond to the mounting screw insertion holes 7a and 9d. A female threaded portion 10a is provided, and the area around the female threaded portion 10a is bent toward the front side of the vehicle body to form a damper insertion portion 10b, which will be described later.

The damper 11 is made of rubber and is a member for attaching the tail lamp 4 to the bottom surface 3e of the recess 3c of the rear wheel fender 3a, and elastically supports the tail lamp 4 with respect to the rear wheel fender 3a. As can be seen from FIGS. 2 and 3, the shape of the damper 11 includes a locking portion 11a, a damper main body portion 11c, and a fender engaging portion 11d.

The locking part 11a is located in a space formed between the damper insertion part 10b of the board 10 and the damper contact surface 9e as the front surface of the lamp housing 9, and is located in a space between the board 10 and the lamp housing 9. is held in between. Further, the damper main body portion 11
c is formed adjacent to the locking portion 11a and has a hollow portion 11b formed inside.
Further, the fender engaging portion 11d is formed in a substantially truncated conical shape on the front side of the damper main body portion 11c, and extends into a damper locking hole 3d formed in the bottom surface 3e of the recess 3c of the rear wheel fender 3a. This is the part that is inserted and fitted. A total of four dampers 11, one pair each on the left and right, are arranged on the damper contact surface 9e of the lamp housing 9 and the recess 3.
It is located between C. Therefore, when assembling the tail lamp 4 and attaching it to the rear wheel fender 3a, first insert the damper 11 into the damper insertion portion 10b of the board 10 from the rear, and then insert the damper 11 from the rear with the locking portion 11a in contact with the damper 11. The lamp housing 9 into which the bulb 8 has been inserted and the lens 7 are brought into contact with each other and assembled together with the mounting screws 12. Next, the fender engaging portions 11d of the damper 11 protruding from four locations in front of the assembled tail lamp 4 are pressed against the damper locking hole 3d of the rear wheel fender 3a to deform and insert into the damper locking hole 3d. After being fitted, the tail lamp 4 is attached to the rear wheel fender 3a.

In this way, since the damper 11 is interposed between the tail lamp 4 and the rear wheel fender 3a as described above, vibrations from the vehicle body are absorbed and attenuated by the damper 11. can improve durability. Further, when the damper 11 is configured as a member for attaching the tail lamp 4 as in this embodiment, the assembly work can be simplified. Further, the mounting position of the damper 11 to the rear wheel fender 3a is a recess 3c formed in the rear wheel fender 3a, and since this recess 3c is a highly rigid part, sufficient support rigidity for the tail lamp 4 is ensured. It is becoming possible to do so. Further, the size of the hollow portion 11b formed in the damper main body 11c of the damper 11 can be set arbitrarily, and thereby the elastic supporting force of the tail lamp 4 to the rear wheel fender 3a can be set freely. will be possible. That is, for example, by appropriately setting the size of the hollow portion 11b, it is possible to avoid the resonance point caused by the vibration. Furthermore, since the damper 11 is disposed between the damper contact surface 9e of the lamp housing 9 and the recess 3c of the rear wheel fender 3a, it is not visible from the outside. Therefore, it is possible to ensure a good appearance around the tail lamp installation position.

(Effect of the invention) As described above, according to the invention, since the damper is disposed between the damper contacting surface of the lamp housing and the recess of the rear wheel fender, the tail lamp is connected to the rear wheel fender via the damper. Since the vibrations from the vehicle body are absorbed and attenuated by the damper, the durability of the tail lamp can be greatly improved. The installation position is a recess formed in the rear wheel fender, and since this recess is a highly rigid part, it can ensure sufficient support rigidity for the tail lamp. Since the size of the hollow portion can be set arbitrarily, the elastic supporting force of the tail lamp to the rear wheel fender can be set freely. Furthermore, since the damper is disposed between the damper contacting surface of the lamp housing and the recess of the rear wheel fender, it is not visible from the outside. It is possible to ensure a good appearance around the installation location. In other words, according to the present invention, the tail lamp can be elastically supported on a highly rigid part of the vehicle body while maintaining a good appearance around the tail lamp mounting position, and
Effects such as being able to arbitrarily set the elastic supporting force can be achieved.
