Summary of the Invention

Problems to be Solved by the Invention

[0004] However, for weight reduction, simply reducing the wall thickness of the lamp body may reduce the rigidity of the lamp body. A weight reduction configuration applicable to a lamp body that cannot adopt the configuration of Patent Document 1 is desired.

[0005] The present invention has been made in view of this, and an object thereof is to provide a vehicle lamp with a cord clamp that can achieve weight reduction and improvement in rigidity.

Means for Solving the Problems

[0006] In a vehicle lighting fixture, the lamp body comprises a container-shaped lamp body with an open front and a front cover assembled to the front opening of the lamp body, defining a lamp chamber inside. The rear wall of the lamp body has a vertical wall portion formed in a curved shape that protrudes either forward or backward, with a portion of it cut out, and this vertical wall portion constitutes a part of the lamp body. By being formed as a curved protrusion either forward or backward, it is positioned inside or outside the lamp chamber. A portion of the vertical wall portion protrusion is cut out, allowing a cord to be inserted through the cutout, which functions as a cord clamp. By having the vertical wall portion protrude from the wall surface of the lamp body and constitute a part of the lamp body, rigidity is increased without the need for ribs in the cord clamp formed by the vertical wall portion as in conventional designs. Conventional vertical wall portions require many ribs to increase rigidity, which increases the weight of the lamp body, but this can be avoided. In addition, by constituting a part of the lamp body, the rigidity of the lamp body is improved. This makes it possible to make the lamp body thinner and lighter.

[0007] Furthermore, it is preferable that the front end surface of the vertical wall portion is configured in an arc shape, and the base end of the vertical wall portion is connected to the rear wall of the ramp body via a ridge. The tip of the vertical wall portion is arc-shaped, and the base end is also a curved surface connected via a ridge, and is formed by repeating curved surface irregularities. The vertical wall portion itself is mainly composed of curved surfaces. This allows for better stress distribution than when composed only of flat surfaces, thereby increasing rigidity. For this reason, even when formed with a thinner wall than when composed only of flat surfaces as in the conventional method, the same level of rigidity can be ensured, and weight reduction can be achieved.

[0008] Furthermore, the vertical wall portion is provided extending to define the lamp units arranged within the lamp chamber, and it is more desirable that the cords of the lamp units pass through the notches. The vertical wall portion becomes a wall surface defining multiple lamp units, and the notches become cord clamps for the lamp units, improving the rigidity of both the lamp units and the notches. It can form part of the wall surface while fulfilling the roles of both a lamp unit and a cord clamp, thus integrating multiple functions.

[0009] Furthermore, it is more desirable that the corners of the vertical wall section be constructed as hollow hemispherical shapes. Because the corners of the vertical wall section are hollow, the corners also become curved surfaces, and the continuous unevenness of the curved surface contributes to improving the rigidity of the lamp body wall surface. In addition, when the vertical wall section of the lamp body acts as a cord clamp, the cord is smoothly guided into the inside of the notch by the hemispherical surface provided at the corner.

[0010] Furthermore, it is more desirable that the lamp body's rear wall has a recess that curves toward the front, towards the lamp chamber, and a convex end with an arc shape that protrudes toward the rear, with at least a portion of the edge of the recess forming a part of the lamp body's wall surface. By forming a part of the lamp body's wall surface with curved indentations and protrusions, the rigidity of the lamp body is further improved even when the wall is made thinner and lighter.

[0011] Furthermore, the recess has multiple beams with arc-shaped end faces that extend vertically inside the recess, and girders with arc-shaped end faces that extend horizontally and connect to the beams at both ends. It is more desirable that the beams and girders are formed to constitute a part of the wall surface of the lamp body. By having a part of the wall surface of the lamp body formed in a recess that is recessed toward the lamp room side, with beams that extend vertically and girders that are continuous with the beams at both ends, the rigidity of the lamp body is further improved even when the wall is made thinner and lighter.

[0012] Furthermore, it is more desirable that the vertical wall portion constitutes part of the beam or the girder. The rigidity of the ramp body is further improved when the vertical wall portion is formed from a beam and a girder continuous therewith. [Effects of the Invention]

[0013] As is clear from the above explanation, we can provide a vehicle light fixture with a cord clamp that can be made lighter and more rigid. [Brief explanation of the drawing]

[0015] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative and not limiting to the invention, and not all features or combinations thereof described in the embodiments are necessarily essential to the invention. Furthermore, in the following descriptions of embodiments and modifications, the same components will be denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0016] Figure 1 is a schematic front view of a vehicle lamp 201 according to a preferred embodiment of the present invention. The vehicle lamp 201 is a headlight for a motorcycle and is a combination lamp housing a plurality of lamp units.

[0017] As shown in FIG. 2, the vehicle lamp 201 includes a container-shaped lamp body 202 having an opening 202a formed in the front, and a front cover 204 assembled to the opening 202a in the front of the lamp body 202. The front cover 204 is made of a resin having translucency such as polycarbonate or glass. When the front cover 204 is attached to the opening 202a in the front of the lamp body 202, a lamp chamber S is defined inside.

[0018] Inside the lamp chamber S defined as shown in FIG. 1, a pair of left and right daytime running lamp units DRL, a pair of left and right turn signal lamp units TURN arranged below the daytime running lamp units DRL, and a low beam lamp unit Lo and a high beam lamp unit Hi arranged vertically in the center are accommodated. Each lamp unit (Hi, Lo, TURN, DRL) uses a conventionally well-known configuration, such as a reflective type, a projector type, an irradiation type using a light guide, etc., and the type thereof is not limited.

[0019] FIG. 2 is a vertical end view of the vehicle lamp 201. FIG. 3 is a horizontal end view of the vehicle lamp 201. They are end views cut along the lines A-A and B-B in FIG. 1 respectively. The vehicle lamp 201 is attached to the front portion of a frame (not shown) of a motorcycle. A control unit of an anti-lock braking system (hereinafter referred to as an ABS device U) is also attached to the front portion of the frame and is arranged behind the vehicle lamp 201.

[0020] The lamp body 202 is formed by injection molding using a hard synthetic resin material. As shown in FIG. 2, a seal groove 202b for engaging with a seal leg 204b provided on the periphery of the front cover 204 is formed on the periphery of the opening 202a in the front of the lamp body 202. As shown in FIGS. 1 and 2, on the outer surface of the peripheral portion of the opening 202a in the front of the lamp body 202, vehicle body attachment portions 205a to 205f for attaching to the vehicle body are provided so as to project corresponding to the shape of the attachment portion on the vehicle body side.

[0021] As shown in FIG. 3, the lamp body 202 has a rear wall 220 behind the opening 20a as one of the constituent surfaces. The rear wall 220 is mainly composed of a curved surface (details will be described later), and is connected via ridge lines to a ceiling surface wall, a bottom surface wall, and left and right side walls that project forward as other lamp body constituent surfaces. Each constituent surface of the lamp body 202 has a gentle curved shape, and is gently curved at the edges of each other and continuously connected without any bending parts or steps. Each constituent surface of the lamp body 202 has a shape that is smoothly continuous with the rear wall 220, and is integrally formed, constituting a lamp body 202 in the shape of a soup plate with a small protrusion amount. The lamp body 202 is covered by a dome-shaped front cover 204 that bulges greatly forward.

[0022] As shown in FIGS. 2 and 3, the vehicle lamp 201 is configured so as not to interfere with an ABS device U disposed behind the vehicle lamp 201. Specifically, as shown in FIG. 3, a recess 221 that curves and depresses toward the front lamp chamber S is formed in the rear wall 220 of the lamp body 202. Further, a convex portion 222 that bulges rearward is formed continuously from the outer peripheral edge portion of the recess 221, which is the rear end portion of the recess 221 that bulges forward. The convex portion 222 is provided at at least a part of the outer peripheral edge portion of the recess 221 and is formed along the outer peripheral side edge portion. In the present embodiment, the convex portion 222 is formed over substantially the entire circumference of the recess 221, and the overall outer shape of the recess 221 is formed in a substantially annular shape in accordance with the outer shape of the substantially circular recess 221.

[0023] The recessed portion 221 and the convex portion 222 constitute part of the rear wall 220 of the lamp body 202. The rear wall 220 itself is curved to form the recessed portion 221 and the convex portion 222. The end face perpendicular to the direction of extension of the convex portion 222, which extends in the circumferential direction, is a curved line that convex to the rear, as shown in Figure 3. The recessed portion 221 and the convex portion 222 are continuous at each other's edges and are smoothly connected without bends or steps. Since the recessed portion 221 and the convex portion 222 are mainly composed of curved surfaces and are smoothly continuous without steps, the rear wall 220 is constructed continuously without bends while maintaining a constant thickness. As described above, all of the constituent surfaces of the lamp body 202 are constructed smoothly continuous with the rear wall 220 without bends, and not only the rear wall 220, but the lamp body 202 itself is mainly composed of curved surfaces and is constructed continuously without bends while maintaining a constant thickness.

[0024] Here, the lamp body 202 has many parts that are not shown in the illustration, such as bosses and protrusions for attaching optical elements of each lamp unit, control units, aiming screws, etc. The protrusions 222 are provided on the periphery of the recess 221, although they are interrupted in some places by the aforementioned part attachment parts. The end faces of the protrusions 222, perpendicular to their extending direction, are all configured as curved lines that protrude backward, although their respective radii of curvature, widths, and projection amounts differ. The protrusions 222 are formed on at least a part of the edge of the recess 221, and even if they are provided intermittently in several places by the aforementioned attachment parts, they are formed to border the outer circumference of the recess 221. Similarly, the aforementioned attachment parts may also be provided on a part of the recess 221. In this embodiment, the protrusions 222 are formed along the outer edge of the recess 221 and are formed in an annular shape overall. The protrusions 222, which are formed to protrude smoothly toward the rear in an annular shape, have a semi-donut shape when viewed from behind.

[0025] As described above, the end face shape of the rear wall 220 of the lamp body 202 is composed of a wave-like shape with a series of complex curves. A convex portion 22 is formed in an annular shape around the periphery of the recess 21 that is recessed in the front, resulting in a caldera-like outer shape. The rear wall 220 is integrated with the surrounding walls, namely the ceiling wall, bottom wall, and left and right side walls, and at the boundary, they curve with the same curvature and are smoothly connected in a continuous manner. As a result, the lamp body 202 itself is mainly composed of curved surfaces, the formation of corners is reduced, and the wall thickness is kept generally constant.

[0026] As shown in Figures 2 and 3, the ramp body 202 is configured with a corrugated shape at its end face, without any bends, due to the recesses 221 and protrusions 222. This suppresses stress concentration at the corners, thereby improving rigidity. The improved rigidity also allows for thinner walls, resulting in weight reduction. Furthermore, the wall thickness can be kept roughly constant even at connection points with surfaces that tend to be thicker, further contributing to weight reduction. In addition, connection points with reinforcing members such as ribs and corners tend to be thicker and prone to heat buildup, making them areas where molding defects are likely to occur during resin molding. By reducing these areas, molding defects can also be suppressed. The ramp body 202 may also be configured such that the recesses are recessed towards the rear and the protrusions project forward along the outer edge of the recesses. Even in the reverse configuration, the recesses and protrusions described above form a caldera-like unevenness on the rear wall 220, improving the rigidity of the ramp body.

[0027] Figure 4 shows a schematic rear view of the lamp body 2 as seen from the rear. In the lamp body 202 of this embodiment shown in Figure 4, a first beam 261 and a second beam 262, which constitute a part of the rear wall 220, are formed extending from the upper end to the lower end of the recess 221. The first beam 261 and the second beam 262 continue to extend vertically and connect to the protrusion 222.

[0028] As shown in Figure 4, the first beam 261 extends vertically within the recess 221, positioned slightly to the left of the center when viewed from the rear of the rear wall 220, and is connected at its upper and lower ends to the protrusions 222 provided on the outer circumference of the recess 221. The second beam 262 extends vertically within the recess 221, positioned slightly to the right of the center when viewed from the rear of the rear wall 220, and is connected at its upper and lower ends to the protrusions 222 provided on the outer circumference of the recess 221.

[0029] The upper and lower edges of the protrusions 222 are smaller in both protrusion and width than the right and left edges of the protrusions 222 (see Figures 2 and 3), and the vertically extending first beam 261 and second beam 262 extend roughly from the upper end to the lower end of the rear wall 220. As shown in Figures 2 and 3, the rear wall 220 without the first beam 261, second beam 262, and the girder 271 (described later) is referred to as the rear wall body 229.

[0030] Both the first beam 261 and the second beam 262 have end faces perpendicular to the extension direction, i.e., horizontal end faces, which are curved lines that are convex toward the rear (see Figure 3), and form part of the rear wall 220. Furthermore, each beam is smoothly connected to the rear wall body 229 via ridges, and the corresponding end face shapes of the ramp body 202 are constructed continuously without bends while maintaining a constant thickness.

[0031] The first beam 261 and second beam 262, which extend long in the vertical direction, give the ramp body 202, including the rear wall 220, a structure that is resistant to deformation under load. Since the first beam 261 and second beam 262 themselves are curved surfaces that distribute stress, the rear wall 220 has a more rigid structure that is more resistant to deformation. As a result, the rigidity of the ramp body 202 is improved, and this increased rigidity allows for thinner walls and thus weight reduction.

[0032] As shown in Figure 2, the recess 221 and the protrusion 222, and the first beam 261 and second beam 262 formed on the protrusion 222, are connected via ridges. While maintaining the shape of each end face as a curved line that is convex backward / convex forward, adjacent parts are connected smoothly and continuously by curving with the same curvature without forming steps or corners.

[0033] Furthermore, the rear wall 20 is connected to the vertical walls, which are the ceiling wall, bottom wall, and side wall, via the thymus, and at the boundary, both are curved with the same curvature and are smoothly and continuously connected. As a result, the end face shape of the ramp body 2 is composed of a wave-like structure with a series of complex curves. Therefore, the ramp body 2 itself is mainly composed of curved surfaces, reducing the formation of corners and keeping the wall thickness generally constant. The rigidity of the ramp body 202 is improved, and the thickness of the ramp body 202 can be reduced.

[0034] Furthermore, as shown in Figure 4, a first girder 271 extending in the left-right direction is formed approximately in the center of the rear wall 220, connected to the first beam 261 and second beam 262 extending in the vertical direction. As shown in Figure 3, the first girder 271 also constitutes a part of the rear wall 220 of the ramp body 202, and the end face shape (vertical end face) perpendicular to the extension direction is configured as a curved line. In this embodiment, the vertical end face of the first girder 71 is a curved line that is convex toward the rear.

[0035] As shown in Figure 4, the addition of the first girder 271 extending horizontally causes the rear wall 220 to have a wave-like shape with repeated undulations on its end surface in the vertical direction as well. Since the first girder 271 itself is a curved surface that distributes stress, the rear wall 220 has a more rigid structure that is more resistant to deformation. This improves the rigidity of the ramp body 202, and the improved rigidity allows for thinner walls and thus weight reduction. Since a portion of the rear wall 220 becomes a beam / girder, the rigidity of the ramp body 2 can be improved without adding any reinforcing members.

[0036] In addition, since the first beam 261 and the second beam 262 extend vertically, and the first girder 271 extends horizontally and connects to both beams at both ends, the first beam 261, the second beam 262, and the first girder 271 form an H shape. The H-shaped reinforcement is strong against both vertical and horizontal loads, and firmly reinforces the ramp body 202. The rigidity of the ramp body 202 is further enhanced by the H-shaped arrangement of the first beam 261, the second beam 262, and the first girder 271 on the rear wall 220.

[0037] Furthermore, as shown in Figure 4, a second girder 272 extending in the left-right direction is formed below the first girder 271 on the rear wall 220. The second girder 272 also constitutes a part of the rear wall 220 of the lamp body 202, and the end face shape (vertical end face) perpendicular to the extension direction is configured as a curved line. However, in this embodiment, as shown in Figure 3, the vertical end face of the second girder 272 has a curved line shape that is convex forward toward the lamp room S, unlike the first girder 271 which is convex backward. The left and right ends of the second girder 272 are also connected to the first beam 261 and the second beam 262 which extend in the vertical direction, and together with the first beam 261 and the second beam 262, they form an H-shape, thereby constructing a robust lamp body 202 that is strong against loads in both the vertical and horizontal directions, and further increasing the rigidity of the lamp body 202 through improved rigidity of the rear wall 220. The first beam 261 and the second beam 262 have hollow cylindrical sections, with the first girder 271 convex towards the rear and the second girder 272 convex towards the front, and both are configured as vertical wall sections.

[0038] As shown in Figure 3, the front end face 271c of the first girder 271 and the front end face 272c of the second girder 272, which are perpendicular to the extension direction, i.e., within the vertical end face, are both formed in a curved arc shape. The base ends of the first girder 271 and the second girder 272 are smoothly connected to the rear wall of the ramp body 202 via ridges 271d and 272d, respectively, which makes it easier to distribute stress and increases the rigidity of the ramp body 202 through improved rigidity of the rear wall 220. Furthermore, the first girder 271 and the second girder 272, which are provided in parallel, are formed as a wavy curved surface with smoothly continuous irregularities at the boundary indicated by reference numeral 273 within the vertical end face, which further makes it easier to distribute stress and increases the rigidity of the ramp body 202 through improved rigidity of the rear wall 220. Note that the direction in which the first girder 271 and the second girder 272 protrude does not matter, whether it is forward or backward.

[0039] Next, the notch 281 formed in the second girder 272, which is a vertical wall section, will be described with reference to Figures 5 and 6. The notch 281 has a convex shape toward the front and is a recessed shape formed by cutting out a part of the horizontally extended second girder 272 both vertically and backward, and functions as a cord clamp section inside the lamp chamber S.

[0040] Conventional cord clamp sections were conceived by, for example, extending a plate-shaped vertical wall horizontally and forward from the flat rear wall of the lamp body, and then cutting out a portion of it vertically and rearward. However, flat vertical walls tend to lack strength, so it was necessary to reinforce them by making the vertical wall thicker or by forming multiple reinforcing ribs on the top and bottom. This reinforcement had the problem of increasing the weight of the lamp body.

[0041] In contrast, the vertical wall portion of this embodiment, i.e., the second girder 272, as shown in Figures 2, 5, and 6, is composed of a smoothly continuous curved surface in which a part of the rear wall 220 is curved to protrude forward within the vertical end plane cut along the left-right direction. This allows sufficient rigidity to be obtained without reinforcement, eliminating the need for thick walls or ribs, and enabling weight reduction through thinning. Furthermore, the first girder 271, which is the vertical wall portion, constitutes a part of the rear wall 220 of the ramp body 202, thereby contributing to the improvement of the rigidity of the ramp body 202 itself, including the rear wall 220.

[0042] Furthermore, the notch 281 shown in Figures 5 and 6 is formed in the second girder 272 by discontinuing a portion of the second girder 272, which is a vertical wall portion that curves to be convex toward the front. The notch 281 is defined by an opening 281a, a side wall portion 281b, and a rear surface 282c. Specifically, as shown in Figure 6, the notch 281 is composed of a corrugated curved surface, with the opening portion 281a viewed from above being a 1 / 4 hollow spherical surface facing each other, the side wall portion 281b being a semi-cylindrical surface facing each other, and the rear surface 282c being a concave curved surface that smoothly continues from the side wall portion 281b. As a result, the second girder 272 can maintain high rigidity by distributing stress even near the location where the notch 281 is formed.

[0043] Furthermore, the opening 281a of the notch 281 is composed of opposing 1 / 4 hollow spherical surfaces, and its front end is wide and continuous with the side wall 281b by a smooth convex arc surface, thus also providing a guiding effect that makes it easier to guide the power supply cord to the side wall 281b.

[0044] Furthermore, as shown in Figures 5 and 6, the second digit 272 has convex-shaped component mounting sections 272a and 272b on the left and right sides of the notch 281. The component mounting sections 272a and 272b are parts of a curved surface that is convex towards the front and is curved to protrude further forward than other parts of the second digit 272. They are formed from a collection of hollow curved surfaces that do not have bent surfaces, and have sufficient rigidity even if they are longer forward than other parts of the second digit 272. Therefore, by providing a boss section (not shown), heavy components can be supported. The notch 281, which functions as a cord clamp section in the lamp chamber S, is positioned in the left-right direction by, for example, fitting and holding power cords that extend vertically from some lamp unit provided in the component mounting sections 272a and 272b.

[0045] Furthermore, the second girder 272, which is a vertical wall section, is formed as a partition for multiple lamp units such as lamp units (Hi, Lo), and the power cords of the multiple lamp units defined by the partition are positioned and held by being inserted through the notch 281.

[0046] Although the notch 281 is formed in the second beam 272, it may also be formed as a horizontally cut-out notch in either or both of the first beam 261 or the second beam 262, which are vertical wall sections, to function as a cable clamp section that holds cables extending laterally outside the lantern room S. Alternatively, the notch 281 may be formed in the first beam 271, which is a vertical wall section, to function as a cable clamp section that holds cables extending vertically outside the lantern room S.

[0047] Furthermore, the vehicle body mounting portions 205a to 205f, to which the lamp body 202 is attached to the vehicle body, are constructed to be thick and highly rigid, as these are the locations where the vehicle lighting fixture 201 is attached. Here, the vehicle body mounting portion 205a, provided on the upper edge of the outer surface of the lamp body 202, is wide and has two mounting holes 206a and 206b. The right-side mounting hole 206a, which is formed as a pair on the left and right, is formed on the extension of the first beam 261 that extends in the vertical direction. Similarly, the left-side mounting hole 206b is formed on the extension of the second beam 262 that extends in the upward direction.

[0048] As mentioned above, the rigidity of the vehicle body mounting portion 205a is increased by attaching it to a vehicle body (not shown), and in particular, the mounting holes 206a and 206b through which the engaging portion and engaging member are inserted are thicker and more rigid. Since the mounting holes 206a and 206b are provided on the extensions of the first beam 261 and the second beam 262, the high rigidity of the vehicle body mounting portion 205a improves the rigidity of the first beam 261 and the second beam 262, and thus the rigidity of the lamp body 202 is also improved. Similarly, vehicle body mounting portions 5b and 5f are formed on the extensions of the first girder 271 which extends in the left-right direction. Since the highly rigid vehicle body mounting portions 5b and 5f are provided on the extensions of the first girder 271, the rigidity of the first girder 271 and, consequently, the rigidity of the lamp body 202 is improved.

[0049] In this embodiment, two beams and two girders are provided, but this is not limited to this configuration; three or more beams and one or more girders may be provided. As long as they are configured in a curved shape, the convex direction of each end face of the curved line may protrude in the same direction, either forward or backward, or in different directions.

[0050] Although preferred embodiments of the present invention have been described above, these embodiments are merely examples of the present invention, and it is possible to combine them based on the knowledge of those skilled in the art, and such forms are also included within the scope of the present invention.
