BACKGROUND OF THE INVENTION
The present invention relates to a lighting device for a two-wheeled vehicle, and more particularly to a lighting device for a two-wheeled vehicle in which a built-in lighting device is protected against water.
[0002]
[Prior art]
In general, a bar handle of a motorcycle such as a scooter is covered with a handle cover made of a synthetic resin, and a lighting device such as a headlight or a blinker is built in the handle cover. In such a lighting device, since the housing is formed separately from the handle cover, the mold for molding becomes complicated, and assembly adjustment after molding is complicated. Therefore, a handle cover formed integrally with the housing of the lighting device has been proposed in order to eliminate such problems (Japanese Utility Model Publication No. 3-26062).
[0003]
[Problems to be solved by the invention]
In the case of a lighting device in which a handle cover, a reflector, and a socket are integrally formed, there are the following problems. That is, in a structure in which the handle cover and the housing are integrated, water such as rain that has fallen on the front lens cannot escape to the rear of the housing, and the housing and the lens are joined from the mating surface. Easy to penetrate inside.
[0004]
By the way, as a lens of a lighting device, a lens having a shape having a light diffusion function called fish-eye cut has been conventionally used. Due to this fish-eye cut, the inside of the lighting device was difficult to see, and even when there was some water immersion, the merchantability was not extremely deteriorated in appearance. However, in recent years, a lighting device has been used in which a special cut called MR (multi-reflector) cut is made on the inner surface of the housing, that is, the reflector surface, while no fish-eye cut is made on the lens side. . As a result, there is a problem that water that has entered the lighting device and clouding of the inner surface of the lens can be easily seen from the outside, and the merchantability is reduced in appearance.
[0005]
An object of the present invention is to solve the above-mentioned problems and to provide a lighting device for a two-wheeled vehicle in which sufficient measures against moisture are taken while maintaining ease of molding.
[0006]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a reflector part integrally formed with a handle cover main body, a lamp bulb attached to the front surface of the reflector part, and a lens provided on the front face of the lamp bulb. In the two-wheeled vehicle lighting device, the drainage hole provided in the lower part of the junction surface of the reflector portion and the lens, and the junction of the reflector portion and the lens for waterproof sealing between the reflector portion and the lens There is a first feature in that the portion is provided with a seal member arranged in a state where the drain hole is kept open.
[0007]
According to the first feature, water falling from the front is blocked by the sealing member and does not enter the inside. Moreover, since the water which entered temporarily is discharged | emitted from a drain hole, it does not remain in a lighting device for a long period of time.
[0008]
Further, in the present invention, the reflector portion is provided in a light housing for a winker provided on the left and right of the headlight, and the light housing protrudes backward from the headlight side end portion, A second feature is that at least ribs composed of vertical ribs extending in the vertical direction are provided.
[0009]
According to the second feature, it is possible to eliminate the water that has entered from the handle cover end side from falling to the headlight side, and the water that has entered from the gap between the headlight and the blinker light can be removed from the blinker light side. It flows avoiding the drain hole.
[0010]
In addition, the present invention has a third feature in that the rib has a horizontal rib formed so as to protrude from the vertical rib in the horizontal direction and cover the upper part of the drain hole. According to the third feature, it is possible to prevent water dripped from above from directly falling on the drain hole.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings. FIG. 1 is a view showing an appearance of a handle cover of a motorcycle according to an embodiment of the present invention, and in particular, is a plan view of a front division cover that covers a bar handle in combination with a rear division cover. In FIG. 1, a left lens 2 and a right lens 3 of a winker portion are attached to the handle cover 1. The left and right lenses 2 and 3 are fitted into the handle cover 1 via a waterproof packing described later. The left and right lenses 2 and 3 are cut, but unlike the fish-eye cut, this cut is for diffusing the light from the light only in the vertical direction. The inside is easy to see. A window 4 for accommodating a headlight is formed between the two blinker portions covered with the left and right lenses 2 and 3, that is, in the center portion of the handle cover 1. Members 5 and 6 are hooks that engage with a unit including a headlight, and holes 7 and 8 are mounting holes for the rearview mirror.
[0012]
2 is a plan view showing the right side portion of the handle cover 1, FIG. 3 is a front view thereof, and FIG. 4 is a rear view thereof. In particular, FIG. Since the handle cover 1 is a right and left object, only the right side portion will be described, but the left side portion is of course formed similarly. A groove 10 for receiving the edge of the right lens 3 is formed around the front portion of the winker housing 9 (FIG. 3). The groove 10 is provided with an engagement hole 11 for hooking a projection (described later) formed on the edge of the right lens 3 to fix the lens 3 to the winker housing (FIG. 4). An MR surface (multi-reflector surface) 12 is formed on the bottom (back wall) of the winker housing 9 for diffusing the light of the lamp in a predetermined multi-direction. The multi-reflector surface 12 is composed of a number of step surfaces having different formation angles.
[0013]
Although packing is provided between the winker housing 9 and the edge of the right lens 3, water may enter due to deterioration of the packing or a slight gap. Therefore, a drain 13 is provided below the blinker housing 9 so that the water once entered can be easily discharged to the outside. Packing is disposed at the bottom of the groove 10 except for the portion where the drain 13 is provided (see FIGS. 7 and 8 for the packing arrangement). The lighting fixture (socket) 14 is for attaching a turn signal light, and is provided at the bottom center of the turn signal housing 9.
[0014]
Ribs 15 are provided on the back surface of the winker housing 9. The rib 15 has a vertically extending portion (vertical rib) 15a and a laterally extending portion (horizontal rib) 15b. In particular, the lateral ribs 15b project over the drain 13 in a bowl shape and function to prevent water from above from directly falling on the drain 13. Since the drain 13 is provided in the downward direction, the water is not usually submerged from here, but the water-preventing wall function of the vertical ribs 15a and the horizontal ribs 15b can prevent water exposure more effectively.
[0015]
FIG. 5 is a cross-sectional view of the main part of the handle cover showing details of the drain 13. As shown in this figure, the drain 13 is formed by partially removing the component 10 a of the groove 10 that receives the edge of the right lens 3 in the turn signal housing 9. The lateral ribs 15b project from the winker housing 9 to the rear.
[0016]
FIG. 6 is a cross-sectional view of the vertical rib 15a. As shown in this figure, the vertical ribs 15 a project rearward from the bottom surface of the winker housing 9. The vertical rib 15a is provided near the headlight window 4 of the drain 13 (see FIG. 4), and blocks the flow of water from the center portion of the handle cover 1 to the winker housing 9 side.
[0017]
FIG. 7 is a plan sectional view of the winker housing 9, and FIG. 8 is a view taken along arrow AA in FIG. 7. As shown in both figures, the winker lamp 16 is mounted on the bottom of the winker housing 9, that is, at the center of the multi-reflector surface 12, and is covered with an inner lens 17. A packing 18 is sandwiched between the edge 3 a of the right lens 3 and the winker housing 9. A headlight portion HL is attached adjacent to the winker housing 9.
[0018]
FIG. 8B is an enlarged cross-sectional view of an engaging portion between the edge 3 a of the right lens 3 and the winker housing 9. As shown in the figure, the edge 3a of the right lens 3 has a hook-like portion that engages with the engaging hole 11, and when this edge 3a is fitted into the engaging hole 11, it is elastically hooked. The engagement between the edge 3a and the engagement hole 11 is maintained. The packing 18 is pressed against the bottom of the groove 10 at the head of the edge 3a and has a sealing action.
[0019]
Then, the effect by the cover of the said structure is demonstrated. In the handle cover of the present embodiment, since the packing 18 is interposed between the lenses 2 and 3 on the front surface of the winker unit and the winker housing 9, it is difficult for rain or water from car washing to enter the winker housing 9.
[0020]
In addition, since there is a gap between the headlight and the blinker portion in the center of the cover, the water that has fallen is difficult to spread over the entire handle cover and flows intensively along this gap. However, in this embodiment, since the rib 15 is provided near the window 4 for the headlight of the turn signal housing 9, the water entering from the gap flows so as to avoid the drain 13 by being blocked by the rib 15. This operation will be described with reference to the drawings.
[0021]
FIG. 9 is a right side rear view of the handle cover, and shows a state where the two-wheeled vehicle is stood using a side stand. In this figure, since there is no gap on the front surface of the handle cover 1 except between the turn signal housing 9 and the headlight part HL, the water W that has fallen on the handle cover 1 does not disperse, and the headlight part HL and the turn signal housing. It penetrates into the handle cover 1 intensively from the gap with 9. When the side stand is used and the vehicle is fully steered, the vehicle is greatly inclined as shown in the figure, so that the water W that has entered the handle cover 1 in a concentrated manner flows to the winker housing 9 side, and the drain 13 Also get down directly. In the worst case, water accumulated in the handle cover 1 may be submerged in the turn signal housing 9 through the drain 13.
[0022]
However, in this embodiment, since the drain 13 is surrounded by the vertical ribs 15 a and the horizontal ribs 15 b, water flows avoiding the drain 13. This will be described with reference to the drawings. FIG. 10 is a right rear view of the handle cover 1. In the same figure, the water W which is going to flow in from the headlight part HL side is interrupted | blocked by the vertical rib 15a, and flows below along this vertical rib 15a. And the water W which got over the vertical rib 15a at the lower end of the vertical rib 15a flows avoiding the drain 13. On the other hand, even if the water W flows into the turn signal portion side in the middle of the vertical rib 15a, the water W is blocked by the horizontal rib 15b and does not fall directly on the drain 13.
[0023]
The vertical ribs 15a also have the following effects. FIG. 11 is a plan sectional view of the handle cover 1 in a state where the headlight portion is assembled. The headlight portion HL includes a lens 110 and a housing 120, and a headlight 140 is attached in the housing 120. Conventionally, a socket cover has been provided at the rear part of the headlight part HL so that water entering from the end of the handle cover does not fall directly (see FIG. 12). However, in the handle cover 1 according to the present embodiment, since the vertical ribs 15a are provided between the turn signal housing 9 and the headlight part HL, the water W entering from the end of the handle cover 1 enters the rear part of the headlight part HL. It can be prevented from falling directly. Therefore, the socket cover used conventionally can be omitted.
[0024]
As described above, in the present embodiment, the winker housing including the reflector is integrated with the handle cover, and packing as a seal member is provided at the engaging portion between the front lens and the winker housing. In addition, a rib is provided to prevent water from rain and car wash from flowing into the winker housing when it flows into the handle cover.
[0025]
As an example, the lenses 2 and 3 constituting the front surface of the winker are provided with a lens cut for diffusing light. However, when a lens (clear lens) that does not have such a lens cut and the inside of the winker portion can be seen well is employed, the present invention is highly useful particularly in that the merchantability can be improved.
[0026]
In the present embodiment, the wet prevention structure for the turn signal unit has been described. However, this structure can be similarly applied to the headlight part as well as the whiskers part. That is, it is possible to form a drain for draining water while using a packing at the engaging portion between the lens and the housing that covers the front surface of the headlight unit. By adopting such a flooded structure, inundation due to car washing or rain can be prevented even when the reflector, that is, the housing of the headlight part as well as the winker part is integrated with the handle cover.
[0027]
【The invention's effect】
As is apparent from the above description, according to the first to fourth aspects of the invention, the sealing member can prevent water from entering the light housing. Moreover, once the water has entered, it does not stay for a long time and is discharged to the outside through the drain hole. According to the second and third aspects of the present invention, it is possible to prevent water that has entered the handle cover from falling to the headlight side, and to prevent water from entering through the drain hole. Furthermore, according to the invention of claim 4, it is possible to provide a product with a good appearance in which water droplets are not attached to the inside even when a clear lens in which the state of water droplets of water that has entered can be seen from the outside is used. it can.
