In particular, when the flash lamp is disposed in the handle cover, a design scheme or special consideration such as disposing the LED substrate unit is necessary.
The present invention has been made in view of such circumstances, and an object thereof is to provide a position lamp structure for a motorcycle, which enables an LED substrate unit to be easily arranged in a handle cover in which an LED position lamp and a flashlight are arranged.
Technical scheme
According to the invention of the first aspect, in the position lamp structure for a motorcycle in which the LED position lamp and the flasher are arranged in the handle cover, the flasher reflector of the flasher is integrally formed with the handle cover, and the LED substrate unit having the LED substrate of the LED position lamp is attached to the rear surface of the flasher reflector.
According to an invention of a second aspect, in the position lamp structure for a motorcycle according to the first aspect, the LED position lamps each include a light guide that guides light of an LED emitted from a corresponding LED substrate, the light guide is disposed in front of each of the flash reflectors, the light emitted from the LED is guided to the front of each reflector through an opening portion formed on each of the flash reflectors, and the light of the position lamp is emitted to the front of the handle cover through the emission light of the light guide.
According to an invention of a third aspect, in the position lamp structure for a motorcycle according to the second aspect, the LED position lamps each include an inner lens in front of the light guide, the inner lens being disposed at a periphery of each of the flash reflectors, and a plurality of holes allowing light of the light guide to pass therethrough, and a portion covering the opening portion being formed on the inner lens.
According to an invention of a fourth aspect, in the position lamp structure for a motorcycle according to the third aspect, the inner lens and the light guide are fastened together on each of the flasher reflectors by a common fastening screw.
According to an invention of a fifth aspect, in the position light structure for a motorcycle according to the fourth aspect, positioning ribs are formed on both end portions and a central portion of the light guide, respectively, and a fitting portion is formed on one end portion of the light guide, and the common fastening screw is inserted into a boss formed on the inner lens through the fitting portion and through a hole of each of the flasher reflectors to enable fastening with the common fastening screw.
According to an invention of a sixth aspect, in the position light structure for a motorcycle according to the second aspect, a lens cutout is formed on the light guide or on a portion of the rear of the light guide in each of the flash reflectors.
According to an invention of a seventh aspect, in the position light structure for a motorcycle according to the fifth aspect, a light incident portion that allows the light guide to face the LEDs through the opening portion is formed on the light guide, a sealing means that enables sealing between a periphery of the opening portion and each of the LED substrate units is provided, and the common fastening screw is disposed within a range sealed by the sealing means.
According to an eighth aspect of the invention, in the position lamp structure for a motorcycle according to the seventh aspect, a pin and a pin hole are formed on each of the fitting portion and the flasher reflector, respectively, and when properly attached, the pin and the pin hole allow visual confirmation of attachment of the light guide from a rear side of each of the reflectors.
According to an invention of a ninth aspect, in the position lamp structure for a motorcycle according to the eighth aspect, the pin and the pin hole are provided within a range of the seal.
Technical effects
According to the invention of the first aspect, the flash reflector is integrally formed with the handle cover. Therefore, it is possible to ensure that the space in the handle cover is wider than the space in the structure in which a separate flash lamp is attached to the handle cover, and by utilizing the space, the LED substrate unit of the LED substrate having the LED position light can also be attached to the rear surface of the reflector of the flash lamp. Thus, the LED position light can be easily and efficiently arranged in the handle cover in which the flash lamp is arranged, which makes it possible to provide a modern and unique design for the flash lamp and the position light in the handle cover.
According to the invention of the second aspect, in each LED position lamp, the light guide that guides the light of the LED emitted from each LED substrate is arranged in front of each flash reflector, so that the light emitted from the LED can be guided from the opening portion formed on each reflector. This makes it possible to efficiently guide the emitted light of the position lamp forward even if the LED substrate unit is arranged at any position behind the reflector. Therefore, the flexibility of arrangement of the LED substrate unit is further improved, so that it is possible to provide an LED position lamp structure more preferable to a structure including a flash reflector integrated into a handle cover.
According to the invention of the third aspect, an inner lens having a plurality of holes allowing light of the light guide to pass therethrough and covering the opening portion of each reflector is provided in front of the light guide. This makes it possible to create a design of holes optionally through which the emitted light from the light guide can be seen, while effectively masking the open part of each reflector. Therefore, a structure having high design flexibility can be provided.
According to the invention of the fourth aspect, the inner lens and the light guide are fastened together on each flash reflector by a common fastening screw, so that the accuracy of the relative position between the inner lens and the light guide can be increased, and thus the position lamp can be illuminated at a desired position.

According to the invention of the fifth aspect, the positioning ribs are each formed at both end portions and a central portion of the light guide, and a fitting portion through which a common fastening screw is inserted into a boss formed on the inner lens is formed on one end portion of the light guide to enable fastening with the common fastening screw. This makes it possible to increase the accuracy of the relative attachment position between the inner lens and the flash reflector while minimizing the portion fastened by the screw.
According to the invention of the sixth aspect, the lens cut is formed on the light guide, or on a portion of each flash reflector disposed at the rear of the light guide. The lens cut may reflect the light beam traveling backward forward in addition to the light beam traveling forward from the light guide, which makes it possible to secure a desired light emission amount even in the case where the light guide attenuates the light beam of the position lamp.
According to the invention of the seventh aspect, at the opening portion of each flash reflector, there is provided a sealing device for sealing between the flash reflector and the lens, which prevents an influence on the lens or the bulb of the flash due to water intrusion. In addition, the common fastening screw is provided within the range of such sealing, which eliminates the necessity of separately sealing the common fastening screw using a sealing device, and thereby reduces the number of parts.
According to the invention of the eighth aspect, the fitting portion of the light guide is provided with pins, and pin holes are also formed on each reflector. This facilitates fastening of the light guide, because even when the light guide is configured to be fastened from the rear side of the flash reflector, it can be checked whether the light guide is correctly set on the reflector at the fastening portion (common fastening portion).

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As illustrated in fig. 1 and 2, the position lamp structure for a motorcycle according to the present embodiment is applied to a motorcycle having a front cover F attached above a front wheel T, a pair of left and right leg shields S, and an attached handle cover 1 covering the front of a handle H. In the handle cover 1, a left flasher 2a and a right flasher 2b are arranged on both sides (on the left and right sides, respectively) of the handle cover 1, and a headlight 3 is also arranged in the center. In the drawings, reference numerals 2aa and 2ba denote flash bulbs of the left flasher 2a and the right flasher 2b, respectively, and reference numeral 3a denotes a headlight bulb of the headlight 3.
As illustrated in fig. 5, the respective reflectors L of flashers (left flasher 2a and right flasher 2b) arranged in the motorcycle are integrally formed with the handlebar cover 1, and are covered by respective flasher lenses R attached to the front thereof. In particular, in the motorcycle to which the present embodiment is applied, as illustrated in fig. 1 to 9, the LED position lamps 4 are arranged at the peripheries of the respective reflectors L of the left flasher 2a and the right flasher 2 b. For headlamps, a separate headlamp unit is attached to the handle cover.
As depicted in fig. 5, the LED position lamps 4 illuminated by LED substrate units 5a and 5b (see fig. 3) attached to the rear surfaces of the reflectors L each have a light guide 6 and an inner lens 7 attached to the front surface of each reflector L. Specifically, in the LED position lamp 4 according to the present embodiment, the light guide 6 and the inner lens 7 are arranged at the front periphery of each reflector L of the left and right flashers 2a and 2b, and the LED substrate units 5a and 5b are arranged at the rear surfaces of the respective reflectors L.
As illustrated in fig. 3 and 4, the LED substrate unit 5a is attached to the left rear surface of the handle cover 1, and is fixed by inserting and screwing three screws n1 into corresponding screw holes n2 formed on the handle cover 1. As illustrated in fig. 12 and 13, the chassis of the LED substrate unit 5a includes a case C1 and a transparent case C2, and accommodates therein the LED substrate 9 to which the LEDs 10 are attached. Here, the transparent case C2 is made of a material through which light emitted from the LED 10 can pass.
As illustrated in fig. 3 and 4, the LED substrate unit 5b is attached to the right rear surface of the handle cover 1, and is fixed by inserting and screwing two screws n1 into corresponding screw holes n2 formed on the handle cover 1. As illustrated in fig. 14 and 15, the chassis of the LED substrate unit 5b includes a case C1 and a transparent case C2, and accommodates therein the LED substrate 9 to which the LEDs 10 are attached. Here, the transparent case C2 is made of a material through which light emitted from the LED 10 can pass. In a position on the inner surface of the transparent case facing the LED, a tapered convex portion C2a is formed to project the LED light beam. At positions on the outer surface of the transparent casing which the cylindrical light incident portions 6a of the light guide face, three guides C2b are formed which support and position the light incident portions at intervals of about 120 °. This positions the light guide and the LED substrate unit, thereby maintaining the projection accuracy of the LEDs, and further positions the flash reflector and the gasket, and thereby waterproof performance can be maintained. The left side unit 5a of the vehicle body is formed in a shape protruding downward with respect to the right side unit 5b (see fig. 12 and 14), and the protruding portion accommodates a driver (drive circuit) C3 for the right LED and the left LED together.
As illustrated in fig. 10, the light guide 6 configured to guide the light of the LED 10 emitted from the LED substrate 9 is in the shape of an elbow member made of transparent resin. The light guide 6 has: a light incident portion 6a on which light of the LED 10 can be made incident; a fitting portion 6b, an insertion hole 6c being formed at the center of the fitting portion 6 b; and a plurality of positioning ribs r1 to r 5. The light incident portion 6a includes a portion formed to be curved with respect to other portions, and may face the LED 10 disposed at the rear of the reflector L through an opening portion La (see fig. 4) formed on the reflector L to which the light guide 6 is attached to a surface (front surface). With this configuration, light emitted from the LED 10 enters the light guide 6 from the light incident portion 6a, and is guided in the longitudinal direction of the light guide (the direction is the lateral direction of the vehicle body) while being reflected in the light guide, as indicated by the broken-line arrow in fig. 6.
On the light guide 6, along its longitudinal direction, a lens cutout 6d is formed on the flash reflector side (light guide rear surface side) so that light can be diffused to the surroundings when the light from the LED 10 is guided. Therefore, light traveling in the direction of the rear surface of the light guide is reflected to the front side, and light traveling toward the front side is emitted forward from the light guide. On the reflector L of each of the flash lamps (the left flash lamp 2a and the right flash lamp 2b), as illustrated in fig. 6, a lens slit Lb is formed on a portion disposed at the rear of the light guide 6 so that light emitted backward from the light guide 6 can be diffusely reflected forward. These two lens cutouts 6b and Lb make it possible to efficiently emit forward light beams from the LEDs traveling behind the flash, which eliminates the necessity of using high-brightness LEDs even when an illumination system using a light guide is employed.
Positioning ribs r1 to r5 that position and attach the light guide 6 to predetermined positions of the reflector L are formed on both end portions and the central portion of the light guide 6. As illustrated in fig. 6 and fig. 8 and 9, the positioning ribs r1 to r5 are inserted into recessed portions formed at predetermined positions of the reflector L, and thus the light guide 6 can be positioned. The fitting portion 6b is formed in the vicinity of the light incident portion 6a, and a positioning pin p1 is formed on the fitting portion 6 b. The positioning pin p1 is inserted into the pin hole Ld formed at a predetermined position of the reflector L (see fig. 6), which can position the light incident portion 6a and prevent the light guide 6 from rotating when the light guide 6 is attached.
When the common fastening screw B is fastened to the fitting portion 6B of the light guide 6 from the rear side of the strobe reflector L, it is not possible to check whether the light guide 6 is correctly set from the rear side of the reflector on the fastening side. However, with the pin p1 and the pinhole Ld, when the pin p1 is fully inserted into the pinhole Ld, it can be confirmed that the light guide is correctly set, and therefore, it can be confirmed that the light guide 6 is fastened to the reflector L even from the rear side of the reflector. In view of this, the pin p1 and the pin hole Ld are disposed within a range sealed by the gasket 8, similarly to the common fastening screw B.
As can be understood from this description, the space between the flash reflector L and the flash lens R is normally closed, and therefore, even if the opening portion La for the light guide 6, the insertion hole Lc for the common fastening screw, and the pin hole Ld are formed, three holes can be sealed in the area range of one gasket 8. Therefore, the space between the reflector L and the lens R can be effectively kept closed. Therefore, even if a structure is adopted in which the LED substrate unit is attached to the rear side of each flash reflector, and then an opening portion is formed on the reflector to cause the light guide to emit light forward, it is possible to maintain a closed space within the flash.
The fitting portion 6b includes a portion formed at one end of the light guide 6 (disposed inside the vehicle body when attached thereto). By the fitting portion 6B, the common fastening screw B is inserted into a boss 7B (see fig. 11) formed on the inner lens 7 to enable fastening with the common fastening screw B. Specifically, as illustrated in fig. 11, a screw hole 7c is formed on the boss 7b of the inner lens 7. As illustrated in fig. 7, the light guide 6 and the inner lens 7 can be fastened together by tightening the common fastening screw B against the reflector L while inserting the common fastening screw B into the boss 7B through the insertion hole 6c in the fitting portion 6B of the light guide 6. Since the light guide and the inner lens are disposed in front of the strobe reflector, the common fastening screw is screwed from the rear side of the strobe reflector, and thus the screw is screwed without seeing both members. However, the above-described structure of the pin p1 and the pin hole Ld is configured to enable this screwing.
The inner lens 7 serves as a decorative panel that allows the light guide 6 to be in an illuminated state visible from a desired position in front, and covers other parts so as to make them invisible. As illustrated in fig. 11, the inner lens 7 has: a plurality of holes 7a allowing light of the light guide 6 to pass through, the above-described bosses 7b formed on the rear surface, the holding portion 7d, and the positioning ribs s1 and s 2. The holding portion 7d includes a portion that can cover and hold the circumferential surface of the light guide 6, and has holes 7a aligned in the longitudinal direction, four aligned in a row on each of the left and right pairs. In the inner lens 7 according to the present embodiment, on the front surface or the rear surface thereof, a plating process (aluminum vapor deposition process or the like) is performed to prevent light of the light guide 6 from passing therethrough, and thereby light guided in the light guide 6 is emitted forward only from the hole 7 a.
In order to scatter the light from the light guide 6 while covering the bosses 7b on the rear surface and the light incident portion of the light guide and the opening portion of the flash reflector, a ornamental portion 7e having projections and grooves designed on the front surface is continuously formed from the holding portion 7d, and the inner lens 7 is formed in an L shape as a whole. Incidentally, in the inner lens 7, the non-plated portion (gray portion in the drawing) includes a blue lens that allows light to pass therethrough, and on the periphery of the hole 7a, plating is performed on the blue mirror head so that the plated portion does not allow light to pass therethrough.
With the light guide 6 held by the inner lens 7, the light guide 6 and the inner lens 7 are attached to each of the reflectors L of the flashlights (the left flashlights 2a and the right flashlights 2b) from the rear side by a common fastening screw, and the front side of the inner lens 7 is covered in a closed manner by the flashlight lens R so that these components are assembled together. Specifically, the light guide 6 and the inner lens 7 are covered by a flash lamp lens together with each of the flash bulbs 2aa and 2ba of the flash lamps (the left flash lamp 2a and the right flash lamp 2 b).
In the present embodiment, in order to close the space in the flasher in a waterproof manner, as illustrated in fig. 4 and 7, a gasket 8 (sealing means) is provided to seal between the periphery of the opening portion La formed on each of the reflectors L of the flashers (the left flasher 2a and the right flasher 2b) and each of the LED substrate units (5a, 5 b). Here, the common fastening screw B is provided within a range sealed by the gasket 8. Specifically, on each of the reflectors L of the flashlights (the left flashlight 2a and the right flashlight 2b), an opening portion La that allows the light incident portion 6a of the light guide 6 to face the LED 10 is formed, and the periphery of the opening portion La is sealed by the gasket 8. This prevents, for example, rain water from entering the reflector L and also eliminates the necessity of additionally waterproofing a part where the fastening screws are shared.
As shown in fig. 16, the LED substrate unit 5a is attached to the rear side (in the range shown in the drawing) of the left flash 2a, and the light guide 6 is arranged in the upper side of the left flash 2 a. One inner lens 7 is arranged in such a manner as to extend from the inner side (left side in the drawing) of the left strobe 2a toward the upper side. Further, an LED substrate unit 5b is attached to the rear side (in the range shown in the drawing) of the right flash 2b, and a light guide 6 is arranged in the upper side of the right flash 2 b. The other inner lens 7 is arranged in such a manner as to extend from the inner side (right side in the drawing) of the right flasher 2b toward the upper side.
According to the above embodiment, the strobe reflector is integrally formed with the handle cover 1. Therefore, it is possible to ensure that the space in the handle cover 1 is wider than the space in the structure in which a separate flash lamp is attached to the handle cover, and by utilizing the space, the LED substrate unit having the LED substrates (5a, 5b) of the LED position lamp 4 can also be attached to the rear surface of the reflector of the flash lamp. Thus, the LED position lamp 4 can be easily and efficiently arranged in the handle cover in which the flash lamp is arranged, which makes it possible to provide a modern and unique design for the flash lamp and the position lamp in the handle cover 1.
Each LED position lamp 4 according to the present embodiment includes a light guide 6 that guides light of the LED 10 emitted from each LED substrate 9 in front of each flash reflector so that the light emitted from the LED can be guided from an opening portion formed on each reflector. This makes it possible to efficiently guide the emitted light of the position lamp forward even if the LED substrate units (5a, 5b) are arranged in any position behind the reflector L. Therefore, the flexibility of arrangement of the LED substrate units (5a, 5b) is further improved, so that it is possible to provide an LED position lamp structure more preferable to a structure including a flash reflector integrated into the handle cover 1.
Further, an inner lens 7 is disposed in front of the light guide 6, the inner lens 7 having a plurality of holes 7a allowing light of the light guide to pass therethrough and covering an opening portion of each reflector L. This makes it possible to optionally create a design of the holes La through which the emitted light from the light guide 6 can be seen while effectively masking the opening portion of each reflector L. Therefore, a structure having high design flexibility can be provided.
Further, the inner lens 7 and the light guide 6 are fastened together on each strobe reflector by a common fastening screw, so that the accuracy of the relative position between the inner lens 7 and the light guide 6 can be increased, and thus the position lamp 4 can be illuminated at a desired position. Further, the operation of attaching the inner lens 7 and the light guide 6 can be easily and smoothly performed, and the cost can also be reduced by reducing the number of components.
Further, positioning ribs (r1 to r5) are each formed on both end portions and a central portion of the light guide 6, and a fitting portion is formed on one end portion of the light guide 6, and a common fastening screw B is inserted into a boss 7a formed on the inner lens through the fitting portion to enable fastening with the common fastening screw. This makes it possible to increase the accuracy of the relative attachment position between the inner lens 7 and the flash reflector while minimizing the portion fastened by screws.
Further, a lens cutout (6d, Lb) is formed on the light guide 6, or on a portion of each flash reflector disposed behind the light guide 6. The lens cut (6d, Lb) may reflect the light beam traveling backward forward in addition to the light beam traveling forward from the light guide, which makes it possible to ensure a desired light emission amount even in the case where the light guide 6 attenuates the light beam of the position lamp 4.
Further, at the opening portion of each flash reflector, a gasket 8 (sealing means) for sealing between the flash reflector and the lens is provided, which prevents an influence on the lens or the bulb of the flash due to water intrusion. In addition, the common fastening screw is provided within the range of such sealing, which eliminates the necessity of separately sealing the common fastening screw using a sealing device, and thereby reduces the number of parts.
Further, the fitting portion of the light guide 6 is provided with a pin, and a pin hole (Ld) is also formed on each reflector L. This facilitates fastening of the light guide, because even when the light guide 6 is configured to be fastened from the rear side of the flash reflector, it can be checked whether the light guide 6 is correctly set on the reflector L at the fastening portion (common fastening portion).
The present embodiment has been described above, but the present invention is not limited thereto. For example, the LED position lamp 4 may be arranged at other positions on the reflector in the flashers (the left flasher 2a and the right flasher 2b), or the light guide 6 and the inner lens 7 may be formed in other shapes. In the present embodiment, the LED substrate unit 5a on the left side and the LED substrate unit 5b on the right side are different in outer shape and size, but the same shape and the same components can be used by assigning LED driving circuits to the respective LED substrate units. Furthermore, other conventional sealing means may be used instead of the gasket 8.
Practicality of use
The position lamp structure for a motorcycle may be applied to, for example, a structure having a different outer shape or a structure to which another function is added, as long as a flasher reflector is integrally formed with a handle cover in the structure, and an LED substrate unit having an LED substrate of an LED position lamp is also attached to a rear surface of the reflector of the flasher.
