Mode for Carrying Out the Invention

[0012] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative rather than limiting the invention, and not all features or combinations thereof described in the embodiments are necessarily essential to the invention. Also, in the following descriptions of the embodiments and modifications, the same components are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate.

[0013] (Vehicle lighting fixture) FIG. 1 is a schematic front view of a vehicle lighting fixture 1 according to a preferred embodiment of the present invention. The vehicle lighting fixture 1 is a headlamp mounted on the left and right corner portions in front of the vehicle. As shown in FIG. 1, the vehicle lighting fixture 1 includes a container-shaped lamp body 2 having an open front surface, and a front cover 4 assembled to the opening of the lamp body 2. The front cover 4 is made of a resin or glass having translucency, such as polycarbonate. By attaching the front cover 4 to the opening of the lamp body 2, a lamp chamber S is defined inside.

[0014] Inside the defined lamp chamber S, a high-beam lamp unit Hi and a low-beam lamp unit Lo are accommodated. The high-beam lamp unit Hi and the low-beam lamp unit Lo are optical units configured to irradiate light emitted from a light source forward of the vehicle and form high-beam light distribution / low-beam light distribution either alone or in cooperation. Each lamp unit (Hi, Lo) may use a conventionally well-known lamp unit configuration, such as a reflector type, a projector type, or a configuration using a light guide, regardless of its type.

[0015] (Overall shape of the lamp body) The shape of the lamp body 2 will be described in detail. FIG. 2 is a schematic rear view of the lamp body 2.

[0016] The lamp body 2 is formed by injection molding using a hard synthetic resin material. A seal groove 3 for engaging with the seal legs provided on the periphery of the front cover 4 is provided around the periphery of the opening on the front surface of the lamp body 2. At two locations on the left side in the front view of the lamp body 2, openings H1 and H2 for replacing the components of the lamp unit (Hi, Lo) are provided.

[0017] On the outer surface of the peripheral edge of the opening of the lamp body 2, a body mounting portion 5, which is a bracket for attaching the vehicle lamp 1 to the vehicle body, protrudes corresponding to the shape of the mounting portion on the vehicle body side. The body mounting portion 5 protrudes on the upper and left outer surfaces of the lamp body 2. Further, a separate bracket 10 attached to the outer side of the lower right corner portion of the lamp body 2 also functions as a vehicle mounting portion for attaching the lamp body 2 to the vehicle body. The separate bracket 10 will be described later.

[0018] The region on the right side in the front view of the lamp body 2 (right region 2a) will be described in detail. The right region 2a of the lamp body 2 has, as constituent surfaces, a rear wall 6, a ceiling wall 7, a bottom wall 8, and a right side wall 9. The rear wall 6 bulges rearward and is continuously connected to the adjacent ceiling wall 7, bottom wall 8, and right side wall 9 via a ridge line in a curved manner. Also, the ceiling wall 7, bottom wall 8, and right side wall 9 are basically in a convex curved shape that gently bulges toward the outside of the lamp body 2, and are gently curved at their edges and continuously connected without any bends or steps. For this reason, at least the right region 2a of the lamp body 2 is formed in an overall rounded container shape.

[0019] The bottom wall 8 is formed by extending forward from the lower edge of the rear wall 6 and is connected to the seal groove 3 provided at the edge of the front opening of the lamp body 2. The right side wall 9 is formed by extending laterally and slightly forward from the right edge of the rear wall 6 and is connected to the seal groove 3. The ceiling wall 7 has a small extension amount, extends while gently curving rearward and downward from the edge of the seal groove 3, and is connected to the rear wall 6 and is formed substantially integrally with the rear wall 6.

[0020] Therefore, the rear wall 6, the ceiling wall 7, the bottom wall 8, and the right side wall 9 are mainly composed of curved surfaces with a large radius of curvature instead of flat surfaces, and the lamp body 2 is formed in a container shape with the rear wall 6 as the bottom as a whole. Each of the rear wall 6, the ceiling wall 7, the bottom wall 8, and the right side wall 9 forms a container surface in which the curved surfaces are smoothly continuous with each other.

[0021] (Rear wall and beam) On the rear wall 6, a first beam 61, a second beam 62, and a third beam 63 are formed, which constitute a part of the rear wall 6.

[0022] As shown in FIG. 2, the first beam 61 is inclined to the right (left in the front view) when the lamp body 2 is viewed from the rear, and extends from the upper end to the lower end of the rear wall 6. The second beam 62 is inclined to the left (right in the front view) when the lamp body 2 is viewed from the rear, and extends from the upper end of the first beam 61 toward the lower end of the rear wall 6. The third beam 63 extends substantially horizontally along the lower end of the rear wall so as to connect the lower ends of the first beam 61 and the second beam 62. Therefore, the first beam 61, the second beam 62, and the third beam 63 form a triangular shape connected at their ends. Here, the portion of the rear wall 6 other than the components of the beams 61, 62, and 63 is referred to as the rear wall body 69.

[0023] FIG. 3 is an end view of each of the beams 61 to 63 along the cutting line shown in FIG. 2. FIG. 3(A) is an end view along the line A-A in FIG. 2, mainly showing the cross-sectional shape of the first beam 61. FIG. 3(B) is an end view along the line B-B in FIG. 2, mainly showing the cross-sectional shape of the second beam 62. FIG. 3(C) is an end view along the line C-C in FIG. 2, mainly showing the cross-sectional shape of the third beam 63. FIG. 3(D) is an end view along the line D-D in FIG. 2, mainly showing the cross-sectional shapes of the first beam 61, the second beam 62, and the rear wall body 69 and the continuity thereof.

[0024] As shown in FIGS. 3(A) to 3(D), each of the beams 61 to 63 has a cross-sectional shape perpendicular to its extending direction. Although the radius of curvature, width, and protruding amount are different for each, they are all configured in a gently curved substantially arc shape. The protruding direction of the curved surface of each of the beams 61 to 63 may be formed either in the direction of the lamp chamber S (forward) or in the outer direction of the lamp chamber S (rearward). In the present embodiment, each of the beams 61 to 63 is formed as a beam protruding toward the outer direction (rearward) of the lamp chamber S. It is smoothly connected to the back wall body 69 via a ridge line, and the corresponding cross-sectional shape of the lamp body 2 is continuously configured without a bent portion while maintaining a constant wall thickness.

[0025] FIG. 4 is a rear view of the lamp body 2, showing each of the beams 61 to 63 in light ink. As shown in FIG. 4, each of the beams 61 to 63 extends from the upper end portion to the lower end portion of the back wall 6, and has a truss structure based on triangles, such as another beam extending obliquely from the end portion of one beam. Here, the seal groove 3 formed with a wall thickness is incorporated into the truss structure. In particular, the seal groove 3 that constitutes the upper side and the right side of the opening of the lamp body 2 is applicable. With such a configuration, the back wall 6 of the lamp body 2, particularly in the right region 2a, has a structure that is difficult to deform under load. Further, since the beams 61 to 63 themselves have a cross-sectional substantially arc-shaped curved surface that disperses stress, they have a structure with higher rigidity and greater resistance to deformation.

[0026] Therefore, at least the right region 2a of the lamp body 2 of the present embodiment has a higher rigidity structure compared to a lamp body that does not have such a truss structure. By improving the rigidity of the lamp body 2, the lamp body 2 is thinner than the conventional lamp body and has the same rigidity as the conventional lamp body.

[0027] With the above configuration, the lamp body 2 can be thinned and weight-reduced. In addition, because it is thin, it is easily elastically deformed and can be deformed flexibly as a whole, but it has a high-rigidity structure.

[0028] (Separate bracket 10) The separate bracket 10 will be described in detail. FIGS. 5 to 7 show the F portion (lower right corner portion) shown in FIG. 2. The separate bracket 10 is attached to the F portion of the lamp body 2. FIG. 5 is a rear view of the F portion. FIG. 5(A) shows only the lamp body 2, in a state where the separate bracket 10 is not attached (before attachment). FIG. 5(B) shows a state where the separate bracket 10 is attached to the lamp body 2 (after attachment). FIG. 6 is a side view of the F portion. FIG. 6(A) shows only the lamp body 2, in a state where the separate bracket 10 is not attached (before attachment). FIG. 6(B) shows a state where the separate bracket 10 is attached to the lamp body 2 (after attachment). FIG. 7 is a perspective view of the F portion. It is an exploded perspective view of the lamp body 2 and the separate bracket 10. The fixing member is omitted. FIG. 8 shows the separate bracket 10. FIG. 8(A) is a rear perspective view of the separate bracket 10. FIG. 8(B) is a front perspective view of the separate bracket 10. FIG. 9 is an end view taken along the line E-E of FIG. 6.

[0029] The separate bracket 10 is a bracket provided separately from the lamp body 2, and is an engaged member that is directly engaged with the outer surface of the right side wall 9 of the lamp body 2 by an engaging structure provided on the lamp body 2 and is fastened and attached to the lamp body 2 by a fixing member B. In the present embodiment, with the right side wall 9 of the lamp body 2 as the engaging surface, the separate bracket 10 is attached below the outer surface of the right side wall 9.

[0030] As shown in FIGS. 5 to 8, the separate bracket 10 has an outer shape that is long in one direction, and includes a cylindrical portion 11 that mainly constitutes a region (front portion) of one end, a bracket side wall 12 on a vertical plane, a bracket lower wall 13 on a horizontal plane, a boss mounting surface 15 that abuts against a boss provided on the lamp body 2, and a boss support surface 14 that supports the boss mounting surface 15.

[0031] The cylindrical portion 11 is open in the front-rear direction and has only a circumferential side surface. The separate bracket 10 forms a body mounting portion 5 for engaging with the lamp body 2 so that the lamp body 2 can be mounted on the vehicle. Another component is inserted through and engaged with the cylindrical portion 11 of the separate bracket 10 engaged with the lamp body 2. That is, the separate bracket 10 also forms an assembly portion for assembling another component to the lamp body 2. Since the separate bracket 10 not only engages with the lamp body 2 but also has another component assembled thereto, the separate bracket 10 has a strong structure with a plurality of ribs provided.

[0032] The bracket side wall 12 and the bracket bottom wall 13 are formed so as to extend the one side surface and the bottom surface of the cylindrical portion 11. The bracket side wall 12 is an engaging surface for engaging with the lamp body 2, and an engaging portion 12c for engaging with the lamp body 2 is formed thereon. The engaging portion 12c is composed of two substantially parallel engaging recesses 12a formed in a line shape that is recessed toward the inside of the separate bracket 10 and is substantially horizontal, and a line-shaped convex portion 12b that is a relatively convex portion sandwiched between the two substantially parallel engaging recesses 12a. The separate bracket 10 slides and engages along the engaging recess 12a.

[0033] Since the two engaging recesses 12a are provided substantially parallel in the vertical direction, the engaging recess 12a and the line-shaped convex portion 12b are provided in order side by side in the vertical direction as engaging recess 12a, line-shaped convex portion 12b, and engaging recess 12a.

[0034] The engaging recess 12a and the line-shaped convex portion 12b are not formed by changing the wall thickness of the bracket side wall 12, but are formed by deforming the bracket side wall 12 while maintaining a constant wall thickness. Therefore, the engaging portion 12c composed of the engaging recess 12a and the line-shaped convex portion 12b constitutes a part of the bracket side wall 12, and its vertical cross-sectional shape is a waveform.

[0035] The engaging concave portion 12a and the linear convex portion 12b are formed smoothly and continuously without a bent portion. Therefore, similar to the beams 61 to 63 formed on the lamp body 2, even if it is relatively thin, the rigidity can be increased. Further, it is easily elastically deformed and deforms flexibly, but also has high load resistance and is difficult to break. In the present embodiment, the linear convex portion 12b is formed up to the middle of the bracket side wall 12, the two engaging concave portions 12a are merged, and from the middle of the bracket side wall 12, it is formed as one concave portion and extends to the end of the bracket side wall 12.

[0036] The boss mounting surface 15 of the separate bracket 10 is a vertical plane substantially orthogonal to the sliding direction of the separate bracket 10. A through hole through which a fixing member is inserted is formed in the boss mounting surface 15. When the separate bracket 10 slides and engages with the lamp body 2, the boss mounting surface 15 abuts against the boss 2j provided on the lamp body 2. The boss mounting surface 15 is formed at four locations on the separate bracket 10, and is formed at one location above, one location below, and one location on the side of the bracket side wall 12 so as not to interfere with the engagement of the separate bracket 10. The boss support surface 14 supports the boss mounting surface 15.

[0037] On the outer surface of the right side wall 9 which is the engaging surface of the separate bracket 10, a guide rail 2n for engaging the separate bracket 10 is formed. The guide rail 2n is two linear protruding portions protruding outward. This linear protruding portion is referred to as an engaging convex portion 2m. The relatively concave portion sandwiched between the engaging convex portions 2m is referred to as a relative concave portion 2k.

[0038] The relative concave portion 2k constitutes a part of the right side wall 9 of the lamp body 2, and the two engaging convex portions 2m are convexly provided substantially horizontally on the outer surface of the right side wall 9 so that the two are substantially parallel.

[0039] To engage the separate bracket 10 with the lamp body 2, align the engaging concave portion 12a of the separate bracket 10 with the guide rail 2n and slide it from the back to the front. Thereby, the separate bracket 10 is engaged with the lamp body 2.

[0040] When the separate bracket 10 is engaged with the lamp body 2, the boss mounting surface 15 of the separate bracket 10 abuts against the boss 2j provided on the lamp body 2. Therefore, a tapping screw, which is the fixing member B, is inserted through the hole formed in the boss mounting surface 15 and fastened to the inner hole of the boss 2j. Thereby, the separate bracket 10 is fixed and attached to the lamp body 2.

[0041] Conventionally, separate parts were directly assembled to the lamp body. When the separate parts are assembled to the lamp body, the lamp body is distorted by the weight of the separate parts. In order to keep this distortion within the allowable range, the strength of the lamp body was increased by making the lamp body thicker or providing a large number of ribs. However, the additional structure provided to ensure such rigidity increased the weight of the lamp body. Particularly, when the entire lamp body is made thin as in the lamp body of the present embodiment, if a part is made thick to ensure the rigidity of one place, local thickness deviation occurs and defects are likely to occur during the molding of the lamp body, which is not suitable for the thin-wall structure.

[0042] Therefore, in the vehicle lamp 1, while ensuring the rigidity by making the entire lamp body 2 thin, the portion where the separate parts are assembled is provided as a separate bracket 10 configured separately from the lamp body 2 and is attached to the lamp body 2. Thereby, ribs or the like for assembling other parts are provided on the separate bracket 10 to ensure sufficient rigidity, and the lamp body 2 is configured to be thin by applying the above-described structure, thereby achieving optimization as a whole. Thereby, the weight of the lamp body 2 and the vehicle lamp 1 can be reduced.

[0043] As shown in FIG. 9, when the separate bracket 10 is engaged with the lamp body 2, the engaging convex portion 2m enters the engaging concave portion 12a. The outermost inner surfaces of the engaging concave portion 12a abut against the outermost outer surfaces of both sides constituting the guide rail 2n, and the separate bracket 10 is firmly attached to the lamp body 2.

[0044] Specifically, the upper surface of the upper engaging convex portion 2m abuts against the ceiling surface (upper surface) of the upper engaging concave portion 12a, and the lower surface of the lower engaging convex portion 2m abuts against the lower surface (inner surface) of the lower engaging concave portion 12a. In this way, by abutting against the guide rail 2n on the upper and lower surfaces of the engaging portion 12c, the engagement is made stronger.

[0045] In this embodiment, the lamp body 2 has a thin-walled structure, and the right side wall 9 itself has a structure that is easily elastically deformed. Since the lamp body 2 has a structure that is easily elastically deformed, zero clearance or negative clearance can be set so as to abut when the separate bracket 10 slides and engages. The same applies to the bracket side wall 12 of the separate bracket 10. The wall thickness remains constant and the cross-sectional shape is configured to be corrugated so that it has a configuration that is easily elastically deformed while maintaining rigidity. As a result, the component surfaces are easily brought into contact with each other during engagement.

[0046] The two engaging convex portions 2m are formed substantially parallel horizontally. However, in this embodiment, they are formed so as to be slightly inclined with respect to each other and open so that the distance between the two gradually increases from the rear to the front. For this reason, when the separate bracket 10 engages, the engaging convex portion 2m and / or the engaging concave portion 12a and its peripheral portion are elastically deformed and abutted, and the engagement is configured to be strong. When a negative clearance is set in the concave-convex engagement, a local load is applied to the root of the convex portion, and there is a risk of breakage from the root. In this embodiment, the engaging surface and the engaging portion itself are elastically deformed to disperse the load and suppress the occurrence of breakage, and the contact area is increased to make the engagement strong.

[0047] As shown in FIG. 7, a contact portion 2p, which is a linear convex portion, is formed on the right side wall 9 provided with the guide rail 2n. The contact portion 2p is formed so as to abut against the outer surface of the separate bracket 10 when the separate bracket 10 engages.

[0048] As shown in Fig. 8, similarly, a plurality of bracket abutting portions 17 are also formed as convex portions on the outer surface of the separate bracket 10. The bracket abutting portion 17 is formed so as to abut against the surface of the lamp body 2 when the separate bracket 10 is engaged.

[0049] The abutting portion 2p and the bracket abutting portion 17 serve to increase the abutting area and stabilize the engagement when the separate bracket 10 is engaged. By avoiding local loads due to the engagement, the separate bracket 10 as a whole is engaged with the lamp body 2. As described above, the lamp body 2 and the bracket side wall 12 have a structure that is easily elastically deformed, suppressing the concentration of local stress due to abutment, dispersing the stress, and reducing the risk of breakage.

[0050] (Locking structure) Subsequently, the locking structure provided on the lamp body 2 will be described. Fig. 10 is a front view of the lamp body 2. A light driver module (hereinafter referred to as LDM50) to be arranged is arranged in the lamp chamber S. The LDM50 is arranged in the right region in the lamp chamber S and is locked to a locking portion 66 provided on the lamp body 2, and is directly attached to the lamp body 2.

[0051] Figs. 11 to 13 are part G of Fig. 10. Fig. 11(A) shows only the lamp body 2 and the state (before attachment) in which the LDM50 is not attached. Fig. 5(B) shows the state (after attachment) in which the light module LDM is attached to the lamp body 2. Fig. 11 is a perspective view of part G. Only the lamp body 2 is shown (state before LDM50 attachment). Fig. 12 is an end view taken along the line H-H of Fig. 10.

[0052] As shown in Fig. 10, the connector 51 provided on the LDM50 is locked to the locking portion 66 provided on the back wall 6 and is directly fixed to the lamp body 2 by a fixing member (not shown).

[0053] As shown in FIGS. 11 to 13, the locking portion 66 is formed to project toward the lamp chamber S, and its outer shape is substantially triangular prism-shaped. The locking portion 66 is formed by the rear wall 6 projecting forward. Therefore, the locking portion 66 is hollow and constitutes a part of the rear wall 6. The locking portion 66 is mainly composed of a rectangular first side surface 66a and a second side surface 66b, and a triangular upper surface 66c and a bottom surface 66d.

[0054] As shown in FIG. 13, in the rear wall 6, a part of the rear wall 6 curves toward the lamp chamber S to form the first beam 61 and the second beam 62, and further the rear wall 6 projects toward the lamp chamber S to form the first side surface 66a and the second side surface 66b. The first side surface 66a and the second side surface 66b constitute a part of the rear wall 6, and each surface is smoothly continuous. Since the locking portion 66 is a right triangular prism, the first side surface 66a is formed by the rear wall main body 69 bending forward at a substantially right angle. The second side surface 66b is formed by the first side surface 66a bending backward, and the second side surface 66b further bends to become the rear wall main body 69 and is smoothly continuous.

[0055] The locking portion 66 is provided at two positions, upper and lower, of the rear wall 6 in accordance with the arrangement of the two connectors 51 provided on the DML50. The first side surface 66a of the locking portion 66 is formed by bending at a substantially right angle from the rear wall main body 69 and is formed to abut against one surface of the connector 51. In the present embodiment, the first side surface 66a abuts against the connection surface 52 of the connector 51 provided with the connector pins.

[0056] When arranging the DML50, place the bottom surface of the DML50 on the bottom wall 8, arrange the connector 51 between the two locking portions 66, and slide it along the inclined second side surface 66b. When the DML50 is fitted, guided by the locking portion 66, the connector 51 abuts against the first side surface 66a and the DML50 is locked in the arranged position. The locking portion 66 guides the arrangement of the DML50 and locks the DML50.

[0057] As described above, the right region 2a of the rear wall 6 to which the DML50 is attached is mainly composed of a curved surface, is thin but highly rigid, and is configured to be easily elastically deformed. By elastically deforming at least a part of the rear wall 6 to which the DML50 is attached, the DML50 can be easily locked. After locking the DML50, the DML50 is attached to the lamp body 2 by fastening the DML50 with a fixing member (not shown). The locking portion 66 allows for direct and easy placement on the lamp body 2.

[0058] The substantially triangular prism-shaped outer shape of the locking portion 66 facilitates guiding the DML50 by sliding, and one surface (right-angled side surface) of the configured surface abuts against the DML50, making it difficult to come off after locking. Note that the outer shape of the locking portion 66 is not limited to a triangular prism shape and may be a pyramid shape.

[0059] The locking portion 66 is provided in the right region 2a where the beams 61 to 63 are provided. Since the whole is elastically deformed, the load is dispersed throughout and it is difficult to be broken. In the lamp body 2, when attaching the DML50, at least a part of the lamp body 2 is elastically deformed and attached, so it is suitable for the locking portion 66 of this configuration.

[0060] Since the locking portion 66 is configured to be hollow, the outer shape and the contact surface can be made much larger than a convex portion simply protruding from the wall surface, facilitating guiding the DML50 and stably locking the DML50. Also, even if the outer shape is large, the entire locking portion 66 and the surrounding wall surface are elastically deformed, so it is difficult to be broken and it is easy to attach the DML50.

[0061] As described above, the preferred embodiments of the present invention have been described. However, the above embodiments are 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 in the scope of the present invention.
