Detailed ways

Next, preferred embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a side view of a motorcycle 1 on which a tail light device according to an embodiment of the present invention is mounted. The front fork 2 is attached to the front end of the body frame (not shown) of the motorcycle 1, and the front fork 2 supports the shaft of the front wheel WF on the left and right sides so that the front wheel WF can rotate relative thereto. Steering handle 4 can be manipulated to make the front fork 2 turn left and right. A handlebar cover is installed on the steering handlebar 4, and the handlebar cover supports a headlight 5 and a pair of left and right front turning lights 6. In addition, a front fender 3 is arranged above the front wheel WF, and this fender 3 is also supported by the front fork 2 . the

In Fig. 1, the leg guard windshield 8 covers the body frame from top to bottom, and the leg guard windshield 8 is integrated to protect the driver's feet from splashing mud and the like. Engine 7 is fixed, and its top is hoisted on the vehicle body frame. On the rear side of the engine 7, a pivot plate (not shown) combined with the body frame is disposed. The pivot plate pivotally supports and makes swingable a swing arm 10 , which is suspended from the vehicle body via a shock absorber 11 , and which supports and makes rotatable a rear wheel WR. the

A rear fender 12 is disposed above the rear wheel WR. The rear fender 12 is equipped with a rear turn signal 13 and a tail light device 20, wherein the number of the rear turn signal 13 is one on each side, and the tail light device 20 is located in the center of the vehicle width direction. The tail light device 20 of the present embodiment functions as a tail light that is turned on simultaneously with the headlight 5 and as a stop light that is turned on when braking. the

FIG. 2 is a perspective view showing the tail light device 20 . From its appearance, the tail light device 20 includes a base member 21 and a lens 22 mounted on the rear side of the vehicle body of the base member 21 . The lens 22 in this embodiment is composed of a red transparent large lens 23 and a colorless transparent small lens 25 . A circular concave portion 24 is formed on the large lens 23, and the circular concave portion 24 is located on the rear side of the vehicle body of a light bulb 50 (see FIG. 6 ) serving as a light source. In addition, the small lens 25 is integrally connected with the lower end of the large lens 23 , and the colorless light emitted by the small lens 25 can be irradiated to the license plate (not shown) arranged below the tail light device 20 . the

FIG. 3 is a perspective view of the tail light device 20 when the lens 22 is not installed. On the rear side of the vehicle body of the base member 21 is attached a reflector 30 for reflecting the light irradiated by the light bulb 50 to a set range on the rear side of the vehicle body. The reflection mirror 30 is made of a resin thin plate or the like, and the thin plate is subjected to metal vapor deposition or plating processing. Reflector 30 is formed by connecting plate-shaped parts 31 at the upper and lower parts respectively to form a bottomed cylindrical structure. Located between the two plate members 31 in the direction, a notch 32 is formed corresponding to the shape of the small lens 25 on the lower side of the vehicle body of the reflector 30 . The light irradiated from the notch 32 to the lower side of the vehicle body passes through the small lens 25 and is irradiated onto the license plate. the

Furthermore, a plurality of through holes 33 are formed in the pair of left and right plate members 31 of the reflection mirror 30 . In the present embodiment, six elongated through-holes 33 are arranged in parallel along the vertical direction of the vehicle body, and the long sides of the holes are in the front-rear direction of the vehicle body. Furthermore, the end portion of the plate member 31 on the rear side of the vehicle body extends to a position close to the inner surface of the lens 22 . As a result, at night, when the tail light device 20 is viewed from the side of the vehicle body while it is on, the six long-hole-shaped irradiation lights passing through the through holes 33 can be mainly observed. That is, when the two-wheeled motorcycle is viewed from the side of the vehicle body, the long-hole-shaped red strong light emitted from the six vertical through-holes 33 can be observed. the

FIG. 4 is a front view of the tail light device 20 . In this figure, only the state where the half lens 22 is attached to the right side of the tail light device 20 is shown. The same symbols used in this figure as those in the above-mentioned figures denote the same or equivalent parts. The main reflection surface 34 of the reflector 30 has a plurality of long reflection surfaces horizontally in the vehicle width direction arranged in parallel along the vehicle body vertical direction, and these reflection surfaces are formed in a stepped shape along the vehicle body vertical direction. In addition, an attachment hole 35 for attaching a socket 43 (see FIG. 6 ) of the light bulb 50 is provided on the main reflection surface 34 and the base member 21 . This FIG. 4 shows a state in which the light bulb 50 and the lamp socket 43 are not attached to the tail light device 20 . The lens 22 is fixed by screwing two mounting screws 41 into screw holes 40 formed in the lower part of the base member 21 to screw them together. the

As mentioned above, the large lens 23 is formed with a circular recess 24, which is located on the rear side of the light bulb 50. At night, when the tail light device 20 that is lit is viewed from the rear side of the vehicle, the entire large lens 23 is not only It emits red light as a whole, and a circular light in its approximate center can also be observed. the

Fig. 5 is a side view of the tail light device. As mentioned above, because the end portion of the plate-shaped member 31 of the reflector 30 extends toward the vehicle rear side along the shape of the large lens 23 at the rear side of the vehicle body, at the same time, the part connected to the upper part of the plate-shaped member 31 also extends toward the vehicle rear side. Side extension, so, the irradiating light of bulb 50 is mainly irradiated to the rear and the lower side of the vehicle body, and the irradiating light towards the upper side of the vehicle body and the side of the vehicle body is blocked by the reflector 30 . However, since the through-hole 33 is provided on the plate member 31, the irradiated light passing through the through-hole 33 is in the shape of the through-hole 33 and shines toward the side of the vehicle body. When the device 20 is irradiated with light, there is a big difference in what it observes. Thus, when observing the two-wheeled motorcycle 1 at night, as long as the state of the light emitted by the taillight 20 is seen, it can be easily judged whether the vehicle body is traveling in the same direction as the self or traveling laterally relative to the self. the

As mentioned above, even at night, according to the tail light device 20 of the present invention, as long as the observation of the irradiated light to the tail light device 20 is performed, the driving direction of the motorcycle can be easily judged. On a very dark road, by observing the light emitted by the taillight device of the vehicle in front of you, you can judge whether the vehicle is driving in the same direction as you or in a different direction from you. the

In addition, this figure shows the state after the socket 43 of the light bulb 50 was attached. In addition, one upper pin and two lower pins 42 for vehicle body attachment are embedded in the base member 21 . the

Fig. 6 is a cross-sectional view along line A-A of Fig. 4 . The same symbols used in this figure as those in the above-mentioned figures denote the same or equivalent parts. The insertion portion of the light bulb 50 is wedge-shaped, and can be connected to the lamp socket 43 as long as it is inserted. The lamp holder 43 is engaged and fixed to the base member 21 through an annular waterproof sealing ring 44 . The reflector 30 is attached to the base member 21 with three upper and lower screws 45 . Ring-shaped anti-vibration rubber 47 is attached to the three body-mounting pins 42 embedded in the base member 21 , and the tail light device 20 is supported on the side of the vehicle body through the anti-vibration rubber 47 . In addition, the light bulb 50 may be a filament type, or may be a light emitting diode or the like. the

On the inner surface side of the circular concave portion 24 formed on the large lens 23, a plurality of prism mirrors 26 are formed in an annular shape on the inner surface of the outer diameter of the circular concave portion 24. Therefore, when viewing the tail light device 20 from the rear of the vehicle body, the circular concave portion 24 can be seen to have multiple circular shapes. Therefore, this structure further improves the visibility of the tail light device for observers from the rear of the vehicle body. the

Fig. 7 is a sectional view along line B-B of Fig. 4 . In addition to the circular concave portion 24, a plurality of elongated mountain-shaped convex portions are formed on the inner surface of the large lens 23 on the vehicle body rear side, which are directed in the up-down direction of the vehicle body. Therefore, since the mountain-shaped convex portion has a vertical strip-like appearance around the annular shape of the concave portion 24, this structure further improves the visibility of the tail light device for observers and the decorativeness of the tail light device. Furthermore, a waterproof gasket 46 is provided between the large lens 23 and the base member 21 . the

The pair of left and right plate-shaped members 31 of the reflector 30 according to the present embodiment gradually increase in distance in the vehicle width direction as they extend toward the rear side of the vehicle body. In addition, the end surface of the through hole 33 on the vehicle body rear side is closer to the vehicle body rear side than the filament of the light bulb 50 , that is, the position of the light source. the

FIG. 8 is a partially enlarged view of FIG. 7 . This figure shows only the plate-like member 31 on the right side of the vehicle body. In the present embodiment, an inclined surface 33 a inclined rearward in the vehicle width direction is formed on an outer portion of the inner peripheral surface 36 of the through hole 33 in the vehicle width direction when viewed from above. The inclined surface 33 a in the present embodiment has a structure formed by chamfering the outer edge portion of the through hole 33 in the vehicle width direction. By providing the inclined surface 33a, the irradiation range of the reflected light generated by the inner peripheral surface 36 toward the front of the vehicle body can be made narrower than that without the inclined surface 33a. the

In this embodiment, the inner peripheral surface 36 on the inner side in the vehicle width direction of the through hole 33 is not processed, and only the outer portion in the vehicle width direction is processed into the inclined surface 33a. This is because the reflected light generated on the inner peripheral surface 36 on the inner side in the vehicle width direction of the through hole 33 is blocked by the rear fender 12 and the like and cannot be irradiated to the front of the vehicle body, so there is no need to perform processing measures on it. . However, the entire inner peripheral surface of the through-hole 33 may be inclined outward so as not to generate reflected light toward the front of the vehicle body at all. Furthermore, the inclined surface may be formed by a curved surface, or the inclined surface may be formed directly during the injection molding of the through hole 33 instead of obtaining the inclined surface by chamfering after forming the through hole 33 . the

FIG. 9 is a side view of a tail light device 60 according to a second embodiment of the present invention. In the present embodiment, a plurality of circular through-holes 61 are arranged in the plate-shaped member 31 located in the reflector 30 , and the plurality of through-holes 61 are arranged in a row in the vertical direction of the vehicle body. The shape, number, and arrangement of the through holes can be modified in various ways. In a tail light device 70 according to a modified example of the second embodiment of the present invention shown in FIG. 10 , a plurality of circular through-holes 71 are provided, which are arranged in a staggered manner in the front-rear direction of the vehicle body. In addition, in the tail light device 80 of the modified example of the second embodiment of the present invention shown in FIG. In a tail light device 90 according to a modified example of the second embodiment of the present invention shown in FIG. 12 , through-holes 91 are arranged in an isosceles triangle whose vertex points to the front side of the vehicle body. In any of the above-mentioned embodiments, for the light irradiated by the taillight device, the effects seen from the rear of the vehicle body and those seen from the side of the vehicle body can be clearly different. the

FIG. 13 is a front view of a tail light device 100 according to a third embodiment of the present invention. In this embodiment, the feature of the taillight device is: a convex portion 101 is provided on the side of the large lens 23, which is approximately the same shape as the through hole. The protrusion 101 is located at a position corresponding to the outside of the through hole 33 in the vehicle width direction, and has a function of diffusing the irradiated light passing through the through hole. When the convex portion 101 in this embodiment is used in combination with the through hole shown in the first embodiment, the convex portion has a semicircular shape when viewed from the rear of the vehicle body, and a long hole shape when viewed from the side. The visibility of the shape of the through-hole 33 can be further improved by providing the protrusion 101 , and it can be observed from the appearance that the through-hole 33 is independently illuminated by a light source such as a light-emitting diode. the

The shape, number and arrangement of the protrusions provided on the large lens 23 can be modified in various ways. As shown in FIG. Convex part 111. In addition, instead of the convex portion, the convex portion may be replaced with a concave portion having substantially the same shape as the through hole to concentrate the irradiation light from the light source, and the convex portion or concave portion may be provided on the inner surface (mirror side) of the large lens 23 . the

As described above, according to the vehicle tail light device according to the present invention, the plate-shaped member of the reflector is arranged on the left and right sides of the light source in the vehicle width direction, and since the through hole through which the irradiated light of the light source can pass through the hole is provided , so when the tail light device is observed from the rear of the vehicle body, the observed light is obviously different from that observed when the tail light device is observed from the side of the vehicle body. Therefore, the driving direction of the vehicle can be easily judged by observing the light emitted by the tail light device . the

Furthermore, regarding the shape and arrangement of base members, lenses, reflectors, plate members, etc., the shape and number of light bulbs, the shape and arrangement of through holes, the shape of inclined surfaces formed on the inner peripheral surface of through holes, etc. In other words, the present invention is not limited to the above-described embodiments, and various modifications can be made. The application of the tail light device of the present invention is not limited to two-wheeled motorcycles, but can also be applied to various vehicles such as tricycles or four-wheeled vehicles. the
