Description

[Technical Field]

[0001] The present invention relates to a lamp unit. [Background technology]

[0002] Conventionally, lamp units in which an LED (Light Emitting Diode) board installed inside an outer lens is hidden from the outside are known (see, for example, Patent Document 1). In the lamp unit described in Patent Document 1, the LED board is fixed to the housing via a bracket so as to be aligned with the optical axis of the lamp. A reflector is installed inside the housing below the LED board, and light from the LED is reflected forward toward the outer lens by the reflector. The periphery of the reflector is covered by an extension, and the top of the extension extends upward to hide the LED board. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-69860 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the lamp unit described in Patent Document 1 requires an extension to prevent the LED board from being exposed. Also, because the extension blocks the tool line for fastening the bracket, the extension must be installed on the housing after the bracket has been fixed to the housing, which makes the configuration complicated and is a cumbersome task for the worker.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide a lamp unit that has a simple structure and can maintain a good appearance. [Means for solving the problem]

[0006] One aspect of the present invention is a lamp unit that illuminates the front through an outer lens, and comprises a housing to which the outer lens is attached from the front, a bracket installed on the housing within the outer lens, and a light source board installed on the bracket with one side edge facing forward, wherein the bracket has an installation portion installed on the rear wall of the housing, a support portion that supports the light source board, and a design portion that covers one side edge of the light source board from the front, and the installation portion has an attachment hole formed in it for attaching the bracket to the rear wall of the housing from the front, and the design portion avoids the extension line of the attachment hole, thereby solving the above problem. [Effects of the Invention]

[0007] According to one aspect of the present invention, the lamp unit has a design portion of the bracket that covers the light source board from the front, thereby hiding the light source board. Furthermore, the design portion does not block the tool line to the mounting hole, allowing the bracket to be easily fixed to the housing. Because the tool line is maintained even when the design portion is formed on the bracket, the bracket, which integrates the design portion, support portion, and installation portion, simplifies the structure of the lamp unit while maintaining a good appearance.

[0009] A lamp unit according to one aspect of the present invention illuminates the front through an outer lens. An outer lens is attached to a housing from the front, and a bracket is attached to the housing inside the outer lens. A light source board is attached to the bracket, with one side edge of the light source board facing forward. An installation portion of the bracket is attached to the rear wall of the housing, and the light source board is supported by the bracket's support portion. A decorative portion of the bracket covers one side edge of the light source board from the front, allowing the light source board to be hidden by the decorative portion. A mounting hole is formed in the installation portion for attaching the bracket to the rear wall of the housing from the front, and the decorative portion avoids the extension line of the mounting hole, so the tool line relative to the mounting hole is not obstructed by the decorative portion, allowing the bracket to be easily fixed to the housing. In this way, the tool line is maintained even when the decorative portion is formed on the bracket, and the bracket, which integrates the decorative portion, support portion, and installation portion, allows the lamp unit to have a simple structure while maintaining a good appearance. [Example]

[0010] A saddle-type vehicle equipped with a lamp unit according to this embodiment will now be described with reference to the accompanying drawings. Fig. 1 is a left side view of the saddle-type vehicle according to this embodiment. Fig. 2 is a schematic diagram of a lamp unit according to a comparative example. In the following drawings, arrow FR indicates the front of the vehicle, arrow RE indicates the rear of the vehicle, arrow L indicates the left side of the vehicle, and arrow R indicates the right side of the vehicle.

[0011] As shown in Figure 1, a scooter-type saddle-ride vehicle 1 is configured by attaching various covers to an underbone-type body frame (not shown) as the exterior of the vehicle. A front frame cover 11 is provided at the front of the vehicle, and a front leg shield 12 that protects the rider's legs is provided behind the front frame cover 11. A footboard 13 extends rearward from the lower end of the front leg shield 12, and a seat frame cover 14 is provided behind the footboard 13. The front leg shield 12 and footboard 13 form a space in front of the seat 23 for the rider's feet to rest.

[0012] A lamp unit 30 is provided above the front frame cover 11, and a front wheel 22 is rotatably supported below the front frame cover 11 via a pair of front forks 21. A seat 23 is provided above the seat frame cover 14, and a unit swing-type engine 24 is provided below the seat frame cover 14. The engine 24 is swingably connected to the body frame, and a rear wheel 25 is rotatably supported at the rear of the engine 24. The left side of the crankcase of the engine 24 is covered by a CVT cover 26, and an air cleaner 27 is provided above the CVT cover 26.

[0013] 2(A), a lamp unit 80 of the comparative example has a reflector 83 installed inside a housing 82, and light from an LED 85 is reflected forward by the reflector 83. In such a lamp unit 80, since light from the LED 85 is irradiated toward the reflector 83, it is necessary to install a light source substrate 84 above the reflector 83 so that the LED 85 faces downward. The light source substrate 84 is attached from above to a support base 86 of the housing 82, but because a tool line 87 for attaching the light source substrate 84 faces up and down, the tool line 87 restricts the shapes of the outer lens 81 and the housing 82.

[0014] Specifically, as shown in FIG. 2(B), if the housing peripheral edge 88 is positioned forward of the mounting screws 89 of the light source board 84, the tool line 87 cannot be secured vertically even with the outer lens 81 removed. For this reason, as shown in FIG. 2(A), the housing peripheral edge 88 must be positioned rearward of the tool line 87. Also, to improve the appearance of the lamp unit 80, a design component must be provided that reduces exposure of the light source board 84. Therefore, in the lamp unit of this embodiment, the tool line faces forward and backward, and the bracket for the light source board and the design component are integrated into a single component, simplifying the device configuration.

[0015] The lamp unit will be described with reference to Fig. 3 to Fig. 6. Fig. 3 is a schematic front view of the lamp unit of this embodiment. Fig. 4 is a schematic side view of the lamp unit of this embodiment. Fig. 5 is a perspective view of the bracket of this embodiment. Fig. 6 is a cross-sectional view of the lamp unit of Fig. 3 taken along line AA. For ease of explanation, the housing and outer lens are shown by two-dot chain lines in Fig. 5.

[0016] 3 and 4, the lamp unit 30 is configured such that an outer lens 31 is attached to a housing 41 from the front and illuminates the area ahead through the outer lens 31. The outer lens 31 is formed into a substantially dome shape from a light-transmitting material. A transmitting surface 32 of the outer lens 31 bulges forward, and an upper surface 33 of the outer lens 31 above the transmitting surface 32 is set back, providing a step between the transmitting surface 32 and the upper surface 33. The transmitting surface 32 is exposed from a lamp cover (not shown) or the like, and the upper surface 33, together with the housing 41, is externally covered by the lamp cover.

[0017] The housing 41 has a housing peripheral portion 42 to which the outer lens 31 is attached, a housing main body portion 43 in which a bracket 61 is installed inside the outer lens 31, and a reflector 44 formed on the underside of the housing main body portion 43. A circumferential groove 45 (see FIG. 6) into which the outer edge of the outer lens 31 fits is formed in the housing peripheral portion 42. A fixing clip 46 is provided on the upper surface of the housing peripheral portion 42, and a fixing bolt 48 is provided on a protrusion 47 on the underside of the housing peripheral portion 42. The upper portion of the housing 41 is clipped to the vehicle body by the fixing clip 46, and the lower portion of the housing 41 is screwed to the vehicle body by the fixing bolt 48.

[0018] A plurality of screw bosses 49 protrude from the rear surface of the housing main body 43, and a bracket 61 is screwed onto the plurality of screw bosses 49 from the front. A light source board 51 is attached to the housing main body 43 via the bracket 61, and LEDs 52 are provided on the light source board 51 as light sources. One side edge (front edge) 53 (see FIG. 6) of the light source board 51 faces forward, and the light source board 51 is turned upside down so that the emission direction of the LEDs 52 faces downward. In addition, a wiring hole is formed in the housing main body 43 for passing wiring extending from the light source board 51, and a rubber wiring hole cap (not shown) is attached to the wiring hole.

[0019] The reflector 44 is formed in an arc-shaped cross section so as to reflect the light emitted from the LED 52 toward the transmission surface 32 of the outer lens 31. The optical axis of the light emitted from the LED 52 and the optical axis of the light reflected by the reflector 44 are approximately perpendicular to each other, and the direction of illumination of the lamp unit 30 is directed toward the front of the vehicle. Because the housing 41 is made of a resin material, the reflector 44 is formed by laminating a reflective film by aluminum vapor deposition plating or the like on the surface of a resin wall that is arc-shaped in cross section. Here, the reflector 44 is formed integrally with the housing 41, but the reflector 44 may also be formed separately from the housing 41.

[0020] 5 and 6, the bracket 61 is molded from a resin material to include a horizontal plate-shaped support portion 62, a vertical plate-shaped installation portion 63, and a dome-shaped design portion 65. The support portion 62 extends horizontally, and supports the light source board 51 from above. The installation portion 63 rises from the rear edge of the support portion 62, and is installed on the housing main body 43 (the rear wall of the housing 41). The design portion 65 bulges out from the front edge of the support portion 62, and covers one side edge 53 of the light source board 51 from the front. The bracket 61 also has four reinforcing ribs 69 that connect the upper surface of the support portion 62 to the front surface of the installation portion 63.

[0021] By attaching such a bracket 61 to the housing 41, the inside of the lamp unit 30 is divided into upper and lower sections. A reflector 44 is positioned below the bracket 61, and light emitted from the LEDs 52 on the light source board 51 is reflected forward by the reflector 44. At this time, a lower edge 66 of the design portion 65 is positioned below the LEDs 52 and above the reflector 44. Covering the light source board 51 and the LEDs 52 from the front with the design portion 65 improves the appearance, and the reflected light from the reflector 44 is less likely to be blocked by the design portion 65, so the visibility of the lamp unit 30 is not reduced.

[0022] A mounting portion 63 on the upper side of the bracket 61 is formed with a plurality of mounting holes 64 for mounting the bracket 61 to the housing main body 43. The mounting holes 64 of the mounting portion 63 correspond to the plurality of screw bosses 49 of the housing main body 43, and the bracket 61 is mounted to the housing 41 by fastening mounting screws 70 into the plurality of screw bosses 49 through the mounting holes 64. At this time, the design portion 65 is lower than an extension line L of the center line of the mounting holes 64 so that the design portion 65 avoids the extension line L. Because the design portion 65 does not overlap the mounting holes 64 in a front view (see FIG. 3), the tool line of a tool such as a screwdriver is secured on the extension line L in the front and rear directions.

[0023] Because the design portion 65 does not obstruct the front and rear tool lines, with the outer lens 31 removed, the bracket 61 can be easily attached to the housing 41 by using a tool to tighten the mounting screws 70 from the front. Also, because tool lines are ensured at the front and rear of the lamp unit 30, the tool will not interfere with the housing peripheral portion 42 when tightening the mounting screws 70 from the front. Because the position and shape of the mating parts of the outer lens 31 and the housing 41 are not restricted by the tool lines, the design freedom of the outer lens 31 and the housing 41 is improved.

[0024] In a front view, the design portion 65 is positioned inside the transmitting surface 32 of the outer lens 31, and the design portion 65 bulges out so as to partially cover the installation portion 63 from the front side (see FIG. 3). The design portion 65 bulges out from the support portion 62 to near the mounting hole 64, and a pattern (not shown) is applied to the front surface of the design portion 65. The installation portion 63 protrudes outward from the transmitting surface 32, and overlaps with the upper surface 33 in a portion outer than the transmitting surface 32 (see FIG. 3). The upper surface 33 is recessed in a stepped manner and is covered by the lamp cover, making the installation portion 63 less noticeable. Because the design portion 65 is exposed through the transmitting surface 32, the bracket 61 is recognized as a design component, improving the appearance of the lamp unit 30.

[0025] The assembly work of the lamp unit will be described with reference to Fig. 7. Fig. 7 is a diagram showing an example of the assembly work of the lamp unit of this embodiment.

[0026] 7(A), the light source board 51 is screwed to the support portion 62 of the bracket 61 using a tool 71. A plurality of mounting holes (not shown) are formed in the light source board 51, and a plurality of screw holes (not shown) are formed in the support portion 62. The plurality of mounting holes in the light source board 51 are aligned with the plurality of screw holes in the support portion 62, and the mounting screws 54 are tightened using the tool 71 to attach the light source board 51 to the underside of the support portion 62. Because the lower edge 66 of the design portion 65 of the bracket 61 extends to the underside of the light source board 51, the design portion 65 makes the mounting screws 54 and the light source board 51 less noticeable.

[0027] 7(B), the mounting portion 63 of the bracket 61 is screwed to the housing main body 43 with a tool 71. The multiple mounting holes 64 of the mounting portion 63 are aligned with the multiple screw bosses 49 of the housing main body 43. The tool 71 is brought close to the mounting screws 70 from the front, and the mounting screws 70 are tightened with the tool 71 to attach the bracket 61 to the housing 41. In this case, although the design portion 65 bulges upward, the design portion 65 does not interfere with the tool 71, so the bracket 61 can be easily attached to the housing main body 43 with the tool 71.

[0028] Next, as shown in Figure 7(C), the outer lens 31 is attached to the housing 41 from the front side. The rear edge 34 of the outer lens 31 fits into the circumferential groove 45 of the housing periphery 42, and is then bonded to the circumferential groove 45 of the housing periphery 42 with an adhesive 72 such as hot melt. The mating portion between the housing 41 and the outer lens 31 is sealed with the adhesive 72, ensuring waterproofing. Furthermore, the design portion 65 is exposed from the transmitting surface 32 of the outer lens 31, and the bracket 61 for attaching the light source board 51 is recognized as a design component, thereby improving the appearance of the lamp unit 30.

[0029] A method for forming the bracket will be described with reference to Fig. 8. Fig. 8 is an explanatory diagram of the method for forming the bracket of this embodiment.

[0030] As shown in Fig. 8, the bracket 61 is a resin molded product formed using a fixed mold 73 and a movable mold 74. With the fixed mold 73 and the movable mold 74 clamped together, molten resin is filled into the mold cavity to form the bracket 61. As described above, the installation portion 63 of the bracket 61 is formed in a vertical plate shape along the housing main body 43 (see Fig. 6), and the support portion 62 of the bracket 61 is formed in a horizontal plate shape along the light source substrate 51 (see Fig. 6). With such a bracket 61, it is desirable that the fixed mold 73 and the movable mold 74 be released from the mold in an oblique direction.

[0031] That is, it is necessary to form a mounting hole (not shown) in the support portion 62 for attaching the light source board 51, and it is necessary to form a mounting hole 64 in the installation portion 63 for attaching to the housing main body 43. To form the mounting hole in the support portion 62, the mold release direction needs to be vertical or oblique, and to form the mounting hole in the installation portion 63, the mold release direction needs to be horizontal or oblique. Therefore, in this embodiment, the mold release direction D of the fixed mold 73 and the movable mold 74 when molding the bracket is an oblique direction (for example, a 45-degree oblique direction) that bisects the angle formed by the plate surface of the installation portion 63 and the plate surface of the support portion 62.

[0032] The design portion 65 of the bracket 61 bulges out in a dome shape, but is shaped so that the design portion 65 does not become undercut when the fixed mold 73 and the movable mold 74 are released. That is, the rear half 67 of the design portion 65 rises diagonally forward from the front end of the support portion 62 along the mold release direction D, and the front half 68 of the design portion 65 rises diagonally forward from the front end of the rear half 67 so as to be approximately perpendicular to the mold release direction D. By making the mold release direction D oblique, the installation portion 63, support portion 62, and design portion 65 of the bracket 61 can be molded integrally. Furthermore, because the front half 68 of the design portion 65 is approximately perpendicular to the mold release direction, letters and patterns can be applied to the front surface of the design portion 65 using unevenness.

[0033] As described above, according to the lamp unit 30 of this embodiment, the light source board 51 is covered from the front by the design portion 65 of the bracket 61, so that the light source board 51 can be hidden by the design portion 65. Furthermore, the tool line to the mounting hole 64 is not obstructed by the design portion 65, so that the bracket 61 can be easily fixed to the housing 41. In this way, since the tool line is secured even when the design portion 65 is formed on the bracket 61, the bracket 61, which integrates the design portion 65, support portion 62, and installation portion 63, can simplify the structure of the lamp unit 30 and maintain a good appearance.

[0034] In this embodiment, the light source board and bracket are installed above the reflector, but the light source board and bracket may be installed below the reflector, on both the left and right sides, or on one of the left and right sides. In other words, the light source board and bracket may be installed upside down, or may be installed sideways.

[0035] Furthermore, in this embodiment, an LED is used as an example of the light source, but the type of light source is not limited as long as it can irradiate the outer lens from the back side.

[0036] Furthermore, in this embodiment, the design portion of the bracket bulges upward, but the shape of the design portion is not particularly limited as long as it is formed so as to cover one side edge of the light source substrate.

[0037] Furthermore, in this embodiment, the bracket is formed by a fixed type and a movable type, but the bracket may be formed by a fixed type, a movable type, and a sliding type.

[0038] In this embodiment, the upper surface of the outer lens at the outer portion is recessed in a stepped manner from the transmitting surface, but the shape of the outer lens is not particularly limited.

[0039] In this embodiment, the tool line is provided on the lamp unit in the front-to-rear direction, but it is sufficient that the tool line is provided on the front side of the bracket mounting hole. For example, the tool line on the lamp unit may be provided in the range of +45 degrees to -45 degrees with respect to the front-to-rear direction.

[0040] Furthermore, the lamp unit of this embodiment is not limited to the saddle-ride type vehicle described above, and may be used in other vehicles such as four-wheeled automobiles, etc. Note that the saddle-ride type vehicle is not limited to all vehicles in which the driver rides in a straddling position on a seat, but also includes scooter-type vehicles in which the driver rides without straddling a seat.

[0041] As described above, the first aspect of the present invention is a lamp unit (30) that illuminates the front through an outer lens (31). The lamp unit (30) includes a housing (41) to which the outer lens is attached from the front, a bracket (61) installed in the housing within the outer lens, and a light source board (51) installed on the bracket with one side edge (53) facing forward. The bracket has an installation portion (63) installed on the rear wall of the housing (housing main body portion 43), a support portion (62) that supports the light source board, and a design portion (65) that covers one side edge of the light source board from the front. The installation portion has a mounting hole (64) formed in the installation portion for attaching the bracket to the rear wall of the housing from the front, and the design portion avoids the extension line (L) of the mounting hole. With this configuration, the design portion of the bracket covers the light source board from the front, allowing the light source board to be hidden by the design portion. Furthermore, the tool line relative to the mounting hole is not blocked by the design portion, making it easy to secure the bracket to the housing. In this way, the tool line is maintained even when a design part is formed on the bracket, and the bracket integrating the design part, support part, and installation part allows the structure of the lamp unit to be simplified while maintaining a good appearance.

[0042] In the second embodiment, the design portion of the bracket is bulged out to partially cover the installation portion from the front side of the bracket. With this configuration, the installation portion is covered from the front side by the design portion of the bracket, making the design portion stand out and allowing the bracket to be recognized as a design component.

[0043] In the third aspect, in the first or second aspect, the design portion does not overlap the mounting hole in front view. With this configuration, the tool line relative to the mounting hole is secured in the front-to-rear direction, and the position and shape of the mating portion between the outer lens and the housing are not restricted by the tool line, improving the design freedom of the outer lens and the housing.

[0044] In a fourth aspect, in any one of the first to third aspects, the design part is positioned inside the transmitting surface (32) of the outer lens in a front view, and the installation part protrudes outward from the transmitting surface. With this configuration, the installation part is made less noticeable and the design part is exposed through the transmitting surface, so that the bracket can be recognized as a design part, improving the appearance of the lamp unit.

[0045] In the fifth embodiment, the outer portion of the fourth embodiment is recessed in a step from the transmitting surface, and the installation portion overlaps with this outer portion (upper surface 33) in a front view. This configuration makes the installation portion less noticeable, improving the appearance of the lamp unit.

[0046] A sixth aspect is any one of the first to fifth aspects, in which the installation portion is formed as a plate that conforms to the rear wall of the housing, and the support portion is formed as a plate that conforms to the light source substrate. The diagonal direction (D) that bisects the angle between the plate surfaces of the installation portion and the support portion corresponds to the mold release direction during bracket molding. The rear half (67) of the design portion rises diagonally forward from the front end of the support portion along the mold release direction, and the front half (68) of the design portion falls diagonally forward from the front end of the rear half so as to be approximately perpendicular to the mold release direction. With this configuration, the installation portion, support portion, and design portion of the bracket can be molded as a single unit by setting the mold release direction to an oblique direction. Furthermore, because the front half of the design portion is approximately perpendicular to the mold release direction, letters or patterns can be applied to the front surface of the design portion using irregularities.

[0047] Although the present embodiment has been described, other embodiments may be made by combining the above-described embodiments and modifications in whole or in part.

[0048] Furthermore, the technology of the present invention is not limited to the above-described embodiments, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to technological advances or other derived technologies, it may be implemented using that method. Therefore, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of symbols]
