Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle headlight structure.

[0002]

2. Description of the Related Art A motorcycle headlight is fixed to an upper part of a front fender of a leg shield that covers left, right and upper sides of the front fender. A body case constituting the rear part of the headlight is fixed to the leg shield, and a base for holding the bulb is provided in the body case. The front of the body case is hermetically covered with a lens. An opening for valve replacement and maintenance is formed on the rear surface of the body case corresponding to the position of the base of the valve. This opening is covered with a cover.

[0003] The leg shield is fixed to a vehicle body frame or a vehicle body cover constituting the front side of the vehicle body with a plurality of bolts. Only a very narrow space is formed between the leg shield and the body frame such that the cover on the rear surface of the headlight can be removed. Therefore, when replacing the valve, it is necessary to take out the valve that has been pulled inside the base in a groping state with the cover removed, making the operation extremely difficult. For this reason, conventionally, the leg shield with the headlight attached was removed from the vehicle body, the headlight cover attached to this leg shield was removed, and the bulb was pulled out with your fingers while looking at it, or The bulb was dropped from the base with the leg shield turned upside down and removed.

[0004]

However, the work of attaching and detaching the leg shield to replace the valve involves a large number of bolts (usually about 10 bolts), which is very troublesome. In addition, since the bulb is retracted into the base, it is very difficult to take out the bulb with a finger even when the leg shield is removed.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above conventional technique, and has as its object to provide a headlight structure in which a bulb can be easily attached and detached without removing a leg shield.

[0006]

According to the present invention, there is provided a body case fixed to a vehicle body,
A lens hermetically mounted on the front surface of the body case, a base provided in the body case, a valve detachably mounted on the base from a rear surface thereof, and the body case on the rear side of the base. A headlight structure comprising a removable cover for covering an opening formed in the headlight structure, wherein a photographing member for removing a bulb is provided on a rear surface of the cover.

According to this configuration, the leg shield can be removed by providing the taking member for removing the valve on the cover originally provided on the body case without separately preparing a special tool for taking out the valve. The cover can be removed and the imaging member provided on the rear surface of the cover can be fitted to the valve and the valve can be pulled out while the device is still mounted on the vehicle body, so that the valve can be easily replaced.

[0008] In a preferred configuration, the photographing member comprises a plurality of claws resiliently engaged with the outer peripheral surface of the cylindrical electrode at the rear of the bulb.

According to this structure, the plurality of claw pieces made of an elastic material are pushed into the cylindrical electrode at the rear portion of the bulb and fitted therein, so that the bulb can be easily grasped and grasped. Can be smooth.

In a further preferred embodiment, a protrusion for hooking a valve is provided on the inner surface of the claw piece.

According to this structure, when the claw is pushed into the rear portion of the valve, the force of the projection on the inner surface of the claw resiliently presses against the valve is increased, and the projection is caught on the valve to securely hold the valve. Can be withdrawn.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 respectively
FIG. 1 is a side view and a front view showing a configuration of a front part of a motorcycle having a headlight structure according to the present invention. Front wheel 1
Are mounted on the left and right front forks 2, and the front fender 3 is attached above the front forks 2. The front fork 2 is connected to a steering shaft of a handle (not shown). A body pipe (not shown) is formed by a head pipe (not shown) through which the steering shaft is inserted, a main frame joined to the head pipe, and the like. A leg shield 4 is provided to cover the left and right sides and the upper side of the front fender 3. The leg shield 4 is fixed to the vehicle body frame side by bolts at a plurality of positions (not shown).

A headlight assembly 5 is attached to the center of the leg shield 4 above the front fender 3.
In this example, the headlight assembly 5 includes a head lamp section 7 including two right and left bulbs 6 at a central portion, and flasher sections 8 on both left and right sides thereof.

FIG. 3 is a sectional view of the headlight assembly 5 and FIG.
Is a rear view thereof. As shown in FIG. 3, the headlight assembly 5 includes a lens 9 that covers the front surface of the bulb 6, a body case 10 that holds the lens 9 and is fixed to the body frame side, and is mounted on the back side of the bulb 6. Reflector 1
1, a base 12 for holding the bulb 6 fitted in the reflector 11, and a cover 14 for covering the opening 13 of the body case 10 on the rear side of the base 12. The reflector 11 includes a base 12 for adjusting the optical axis.
In addition, the irradiation angle can be adjusted as shown by a dotted line.

The lens 9 is fitted along the periphery of the body case 10 via a sealing material 15 (for example, a hot-melt or other heat-sealing solidifying sealing material), and is integrally joined and fixed to the front surface of the body case 10. Then, the front surface is hermetically sealed.

The socket 1 is connected to the electrode 16 at the rear of the bulb 6.
7 is fitted and connected to a connector 19 (FIG. 4) via an electric wiring 18, and further connected to a battery (not shown).

The cover 14 is mounted over the opening 13 of the body case 10 via a gasket 22. The cover 14 is rotated and fixed, for example, by pushing a locking piece 14a on the periphery of the cover 14 into a notch (not shown) formed in the inner piece 10a with respect to the inner piece 10a on the body case 10 side. Can be. When removing the cover 14,
This cover 14 can be taken out by rotating in the opposite direction. Therefore, the cover 14 can be easily attached and detached by hand without using a tool.

As shown in FIGS. 4 and 5, a photographing member 21 composed of three claw pieces 20 protrudes from the rear surface of the cover 14. The claw piece 20 is formed on the circumference having a diameter corresponding to the circumference of the electrode section 16 so as to be fitted into the electrode section 16 and pulled out when the bulb 6 is replaced as described later. You.

As shown in FIG. 6, a projection 20a may be formed on the inner peripheral surface of each claw piece 20 as shown in FIG. Due to such projections 20a, when the claw pieces 20 are resiliently pushed in to pull out the bulb 6 as described later, the projections 20a are pressed against the peripheral side surface of the electrode portion 16 of the bulb 6, and are caught.
The valve 6 can be reliably grasped.

FIGS. 7 to 9 are explanatory views sequentially showing the bulb removing operation state in the headlight structure according to the present invention.

FIG. 7 shows a state in which the valve 6 is mounted, similarly to FIG. 3 described above. From this state, the cover 14 and the socket 17 are removed as shown in FIG. The removed cover 14 is turned upside down, as shown in FIG.
The nail 20 of the book is inserted and fitted into the electrode portion 16 of the bulb 6. As a result, the claw piece 20 resiliently engages with the electrode portion 16 and grips it. When the electrode portion 16 of the bulb 6 is grasped by the claw piece 20, it is pulled out to the rear side as shown by the arrow A. Thereby, the valve 6 is connected to the base 1 in the body case 10.
Removed from 2.

Such a bulb removing operation is performed by the front fender 3 and the upper leg shield 4 while the headlight assembly 5 is attached to the leg shield 4 and the leg shield 4 is attached to the vehicle body. The worker can insert the hand through the gap between them and perform the operation easily with only one hand.

[0023]
