A vehicle lamp (1) is provided with: a lamp body (2) having an opening (3) in the front surface thereof; and a front surface lens (4) that is attached to an opening (3) in the front surface of the lamp body (2) and forms a lamp chamber (S) on the inside of the lamp body (2), the lamp body (2) having, on the inside of the lamp chamber (S): component support sections (11), (14), (16); and semi-cylindrical sections (15b, 15c) which are formed so as to surround both sides of the component support section, and which have a semi-cylindrical cross-section.

Description

Technical Field

[0001] The present invention relates to a vehicle lamp having a thin-walled, lightweight lamp body having sufficient strength around a portion where a component support portion is formed. Background Art

[0002] In recent years, with the demand for lighter vehicle lamps from the perspective of carbon neutrality, there has been a demand for lighter weight throughout the lamp body, where components are mounted. Furthermore, to improve safety, the number of components mounted on the lamp body, such as sensors, has increased in recent years, leading to a particular demand for increased rigidity around the component support areas of the lamp body.

[0003] 4 and 5 of Patent Document 1 disclose a lamp body in which ribs are added to a bracket (body mounting portion) for mounting the lamp body on a vehicle body, rather than to a component mounting portion of the lamp body, to enhance the rigidity relative to the increased weight of the lamp body.

[0004] Furthermore, conventionally, components within the lamp chamber (internal lamp components), such as the control unit, were placed in an unused space within the lamp body. For example, in Patent Document 2, the control unit for rotational drive is fixed to an unused space within the box-shaped lamp body. Furthermore, in recent years, there has been a trend toward lightweighting lamp bodies to achieve carbon neutrality. However, simply reducing the wall thickness of the lamp body can reduce its rigidity, making maintaining its rigidity a challenge.

[0005] In addition, conventional lamp bodies are provided with an engaging portion that engages with an engaged component. For example, in Patent Document 3, a front cover is fixed to the lamp body in a preventive manner by an engaging portion having a lance-shaped structure provided on the lamp body.

[0010] Patent Document 3: Japanese Patent Application Laid-Open No. 2017-007214 Summary of the Invention

[0011] Technical problem to be solved by the invention

[0012] For example, the lamp body shown in FIG4 of Patent Document 1 has mounting holes for the first and second light sources. To enhance the rigidity of the lower portion of the mounting holes after the light sources are mounted, it is considered that reinforcing ribs provided on the brackets are provided on the lower side of each light source mounting hole on the lamp body.

[0013] However, although adding ribs to the lamp body increases the rigidity around the light source mounting hole, it increases the weight of the lamp body, which is contrary to the requirement of lightweighting. Therefore, the inventors of this application considered whether the rigidity around the component support part of the lamp body could be strengthened without providing reinforcing ribs.

[0014] One object of the present invention is to provide a vehicle lamp having a lamp body that has sufficient strength around a portion where a component support portion is formed, even though the lamp body is thin and lightweight.

[0015] Another object of the present disclosure is to utilize internal structures of a lamp arranged in an idle space to improve the rigidity of the lamp body.

[0016] In addition, one of the objects of the present disclosure is to improve the rigidity of the lamp body by studying the shape of the lamp body.

[0017] Another object of the present disclosure is to provide a vehicle lamp having a lamp body that has sufficient rigidity even though it is thin and lightweight and that facilitates positioning of mounting components.

[0018] Another object of the present invention is to provide a vehicle lamp having a lamp body having an engaging portion that engages with an engaged member, and capable of achieving weight reduction.

[0019] Technical solutions to technical problems

[0020] One aspect of the vehicle lamp disclosed herein comprises: a lamp body having an opening on the front surface; a front surface lens mounted on the opening on the front surface of the lamp body to form a lamp chamber on the inner side thereof, wherein the lamp body has a component support portion on the inner side of the lamp chamber and a semi-cylindrical portion formed so as to surround both sides of the component support portion and having a semi-cylindrical cross-section.

[0021] Bending stress generated in the component support portion of the lamp body in a direction oblique to the extension direction of the semi-cylindrical portion due to the weight of the fixedly supported component is reduced by the semi-cylindrical portion that is in contact with both sides of the component support portion.

[0022] Another aspect of the present disclosure is a vehicle lamp comprising: a container-shaped lamp body with an opening on the front surface; a front surface cover assembled at the front surface opening of the lamp body to divide the lamp chamber on the inner side; an internal structure of the lamp disposed in the lamp chamber, wherein a plurality of beams having a roughly arc-shaped cross-section formed by a portion of the container surface extend in a truss-like manner on the container surface of the lamp body, and the internal structure of the lamp is supported by at least one of the beams.

[0023] According to this aspect, the internal structure of the lamp is supported by at least one of the beams of the truss structure formed on the lamp body. Therefore, the rigidity of the internal structure becomes part of the rigidity of the beam, reinforcing the beam and improving the strength of the truss structure. The increased rigidity of the truss structure also enables the lamp body to be thinner and lighter.

[0024] Another aspect of the present disclosure provides a vehicle lamp comprising: a container-shaped lamp body having an open front surface; a front surface cover assembled into the front surface opening of the lamp body to divide the lamp chamber on the inner side; and when the lamp body is observed in a cross section along a certain direction, the cross section is formed in a continuous concave and convex manner.

[0025] Another aspect of the present invention is a vehicle lamp comprising: a lamp body that carries a lamp component; a front surface lens that is mounted on the opening of the lamp body to form a lamp chamber on the inner side between the lamp body and the front surface lens, wherein the lamp body has a plurality of protrusions in the form of a bottom cylinder, which are integrally formed in a manner protruding toward either the inner side or the outer side of the lamp chamber, and the base end portion is open, and the plurality of protrusions are respectively formed to be in contact with the outer periphery of the lamp component.

[0026] According to this method, the multiple protrusions, which are formed integrally with the lamp body and have bottomed cylindrical shapes with open base ends and project toward either the outside or the inside of the lamp chamber, improve the rigidity of the lamp body without increasing weight. Furthermore, the multiple protrusions are formed to contact the outer periphery of the lamp component, thereby restricting movement in the contact direction.

[0027] Another aspect of the present disclosure is a vehicle lamp comprising: a container-shaped lamp body having a front surface opening; a front surface cover assembled in the front surface opening of the lamp body to divide the lamp chamber on the inner side; the lamp body having a snap-fitting portion that snaps into engagement with a snap-fitting component, and at least a portion of the snap-fitting portion constituting a portion of a wall surface of the lamp body.

[0028] According to this aspect, the engaging portion can directly engage with the wall surface of the lamp body when engaged, and no engaging member is required, thereby achieving weight reduction of the vehicle lamp.

[0029] Effects of the Invention

[0030] According to the vehicle lamp of the present invention, even without providing ribs, the rigidity against bending stress generated at the portion where the component support portion of the lamp body is formed due to the weight of the mounted components can be increased, thereby achieving weight reduction of the vehicle lamp.

[0099] The following is based on Figure 1 FIG5 through FIG5 illustrate preferred embodiments of the vehicle lighting fixture disclosed herein. The embodiments are provided for illustrative purposes only and do not limit the invention. Not all features described in the embodiments, or any combination thereof, are necessarily essential to the invention. In the following descriptions of the embodiments and variations, identical components are denoted by the same reference numerals, and duplicate descriptions are omitted where appropriate. In the drawings, the vehicle lighting fixture is described with respect to each direction as (front: rear: left: right: top: bottom).

[0100] Figure 1 A front view of a vehicle lamp 1 according to a preferred embodiment of the present disclosure is shown. Figure 1A vehicle lamp 1 includes a lamp body 2, a front lens 4, and multiple brackets 5 for mounting the lamp body 2 on the vehicle body. The lamp body 2 is formed of a resin or the like and, in a vertical cross-section along the front-to-back direction, has a container-like shape with a back wall extending vertically and a bottom wall extending front-to-back, with an opening at its front end. A sealing portion 3, recessed rearward in a groove, is provided around the entire circumference of the opening on the front surface of the lamp body 2, as indicated by reference numeral 3 in the figures. The front lens 4 is formed of a light-transmitting resin or glass or the like and is fixed to the sealing portion 3, defining a sealed lamp chamber S inside the lamp body 2.

[0101] exist Figure 1 The compartmentalized lamp chamber S shown houses a high-beam lamp unit Hi and a low-beam lamp unit Lo, which illuminate headlights forward (toward the front of the drawing). The high-beam lamp unit Hi and the low-beam lamp unit Lo are optical units configured to direct light emitted from a light source toward the front of the vehicle, creating high-beam and low-beam light distributions. Each lamp unit (Hi, Lo) can employ conventionally known structures, such as reflector-type or projector-type lamp units, and their types are not limited.

[0102] Next, the shape of the lamp body 2 will be described in detail. Figure 2 2 is a schematic front view of the lamp body 2. The lamp body 2 is formed by injection molding using a hard synthetic resin material.

[0103] The lamp body 2 comprises a back wall 6, a top surface 7, a bottom surface 8, and left and right side surfaces 9, 9. The back wall 6 bulges rearward and is connected to the adjacent top surface 7, bottom surface 8, and side surfaces 9, 9 in a curved, continuous manner via ridgelines. Furthermore, the top surface 7, bottom surface 8, and side surfaces 9, 9 are generally convexly curved, gently bulging toward the outside of the lamp body 2. They curve gently at their edges, connecting continuously without bends or steps. Consequently, the lamp body 2 as a whole is formed into a container-like shape with rounded corners.

[0104] Figure 2 The bottom surface 8 shown is formed by extending from the lower edge of the back wall 6 toward the front, and is connected to the sealing portion 3 provided at the edge of the opening portion of the front surface of the lamp body 2. The side surfaces 9 are formed by extending from the left and right edges of the back wall 6 toward their respective sides and slightly forward, and are connected to the sealing portion 3. The top surface 7 has a small extension amount, and is gently curved and extended toward the rear and lower direction from the edge of the sealing portion 3 to be connected to the back wall 6, and is formed roughly integrally with the back wall 6. Therefore, the back wall 6, the top surface 7, the bottom surface 8, and the side surfaces 9, 9 are mainly not flat surfaces, but are composed of curved surfaces with a large curvature radius, and the lamp body 2 as a whole is formed into a container shape with the back wall 6 as the bottom, and the back wall 6, the top surface 7, the bottom surface 8, and the side surfaces 9, 9 respectively form container surfaces whose curved surfaces are smoothly continuous with each other.

[0105] In addition, if Figure 2As shown, the lamp body 2 is provided with: three mounting holes 11 (the other two are omitted and not shown), which are used to install the calibration component 12 constituting the calibration mechanism; a sliding support portion 14, which is provided corresponding to the three mounting holes 11. The mounting holes 11 as the first component support portion and the sliding support portion 14 together constitute a component support portion 16, which is installed Figure 3A 、 Figure 4A and Figure 5B The calibration component 12 is shown.

[0106] Then, according to Figures 2 to 5A 、 Figure 5B Detailed description will be given of the peripheral area of the component support portion 16 with reference to the drawings.

[0107] Figure 2 Reference numeral H denotes a schematic diagram A of the surrounding area of the first semi-cylindrical portion 15a, the second semi-cylindrical portions 15b and 15c, and the component support portion 16, which will be described later. Figure 3A It is an enlarged front view A of the area marked H in the figure. Figure 3A 、 Figure 4A 、 Figure 4B This is a partial perspective view of the second half-cylinder portions 15b, 15c and the surrounding area of the component support portion 16 of the lamp body 2 as viewed from various directions. Figure 5A This is an end view of the second semi-cylindrical portion 15 b cut perpendicularly (vertically) along the front-back direction. Figure 5B This is a cross-sectional view obtained by cutting the second semi-cylindrical portions 15 b and 15 c and the component support portion 16 to which the alignment component 12 is attached perpendicularly (vertically) in the left-right direction.

[0108] like Figure 2 、 Figure 4A 、 Figure 5B As shown, the sliding support portion 14 constituting the component support portion 16 is composed of a left end portion 14a, a right end portion 14b, and a bottom portion 14c. The left end portion 14a and the right end portion 14b are integrally formed so as to extend upward from the left and right ends of the bottom portion 14c. The upper end of the left end portion 14a is bent to the right, and the upper end of the right end portion 14b is bent inwardly so as to be opposite to the upper end of the left end portion 14a. Reference numeral 14d indicates a sliding groove formed on the inner side of the left end portion 14a, the right end portion 14b, and the bottom portion 14c. Figure 4A 、 Figure 5B As shown, a groove 14e extending frontward and rearward and recessed downward is provided in the center of the bottom 14c, and the mounting hole 11 is provided above the groove 14e.

[0109] In addition, if Figure 4A and Figure 5BAs shown, the calibration member 12 comprises a flat base portion 12a, a main body portion 12e integrally formed above the base portion, and a pair of left and right spring portions 12c and 12d. The left and right spring portions 12c and 12d are integrally formed so as to face the left and right lower ends of the base portion 12a, extend obliquely downward from the base portion 12a, and generate a downward biasing force by flexing upward.

[0110] like Figure 4A As shown, the base end portion 12b of the calibration component 12 is inserted into the mounting hole 11 of the lamp body 2, as shown in FIG. Figure 5B As shown, the pedestal portion 12a is inserted into the sliding groove 14d of the sliding support portion 14 while the spring portions 12c and 12d are bent upward, thereby being mounted on the component support portion 16. The calibration component 12 is supported by the base end portion 12b being engaged with the mounting hole 11. In addition, the pedestal portion 12a is subjected to an upward force by the spring portions 12c and 12d in contact with the bottom portion 14c, and is urged toward the upper ends of both the left end portion 14a and the right end portion 14b of the sliding support portion. The calibration component 12 is fixed to the component support portion 16 of the lamp body 2 by supporting the base end portion 12b in the peripheral area of the mounting hole 11 and clamping the pedestal portion 12a between the left and right end portions 14a, 14b and the bottom portion 14c of the sliding support portion 14 via the spring portions 12c and 12d.

[0111] In addition, if Figure 2 As shown, the first half-cylinder 15a is formed around the component support portion 16 of the lamp body 2 so as to extend obliquely upward and leftward from the periphery of the mounting hole 11, and the second half-cylinders 15b and 15c are formed so as to surround the mounting hole 11 and the left and right sides of the sliding support portion 14. Figure 2 As shown in the figures to FIG5, the first semi-cylindrical portion 15a is formed on the back wall 6, and has a semi-cylindrical dome shape that is curved and convex toward the front relative to the vertical end face (cross section) of the extending direction. In addition, the second semi-cylindrical portion 15b and the second semi-cylindrical portion 15c are formed on the bottom surface 8, as shown in FIG5. Figure 2 Figures to Figure 4, especially Figure 5B As shown, the vertical end surface (cross section) formed in the extending direction thereof has a curved semi-cylindrical dome shape convex toward the upper side.

[0112] like Figure 2As shown, the upper end portion of the first semi-cylindrical portion 15a is a portion of the sealing portion 3 (the opening portion on the front surface of the lamp body) of the lamp body 2 and is formed continuously with the sealing portion 7a located on the top surface 7. The pair of second semi-cylindrical portions 15b and 15c are formed from the lower end portion 15a of the first semi-cylindrical portion 15a while maintaining integrity with the first semi-cylindrical portion 15a and offset in the left-right width direction. The lower end portions 15b1 and 15c1 of the pair of second semi-cylindrical portions 15b and 15c are respectively formed continuously with a portion of the sealing portion 3 (the opening portion on the front surface of the lamp body) of the lamp body 2, that is, the sealing portion 8b located on the bottom surface 8 opposite the top surface 7 (see FIG. 1 ). Figure 5A The second semi-cylindrical portion 15b is integrally formed so as to be in contact with the left end portion 14a of the sliding support portion 14, and the second semi-cylindrical portion 15c is integrally formed so as to be in contact with the right end portion 14b.

[0113] like Figure 2 As shown in FIG4 , the mounting hole 11 and the sliding support 14 in the component support portion 16 are provided on the second semi-cylindrical portions 15b and 15c of the lamp body 2, surrounding their respective left and right sides. This reduces bending stress generated in a direction oblique to the longitudinal direction of the extension of the second semi-cylindrical portions 15b and 15c. As a result, even without the conventional integral ribs around the mounting hole 11 and at the lower end of the sliding support portion 14, sufficient rigidity against bending stress can be achieved. Consequently, by omitting the ribs, the lamp body 2 and the vehicle lamp 1 can be lightweighted. Furthermore, by integrally forming the second semi-cylindrical portions 15b and 15c with the sliding support portion 14, the sliding support portion 14 can achieve higher rigidity against bending stress than if it were formed separately from the sliding support portion 14.

[0114] In addition, if Figure 2 As shown, the first semi-cylindrical portion 15a and the second semi-cylindrical portions 15b and 15c, which are integrally formed and continuous with the first semi-cylindrical portion 15a, are formed continuously from a portion 7a of the seal portion 3 (the opening on the front surface of the lamp body) located on the top surface 7 to a portion 8a of the seal portion 3 on the opposite bottom surface 8. Thus, by forming the semi-cylindrical portion, formed integrally with the first semi-cylindrical portion 15a and the second semi-cylindrical portions 15b and 15c, formed around the component support portion 16, so that one end is continuous with the seal portion 3 on the top surface 7 and the other end is continuous with the seal portion 3 on the bottom surface opposite the top surface 7, the lamp body 2 not only improves the bending rigidity around the portion of the bottom surface 8 where the component support portion 16 is formed due to the second semi-cylindrical portions 15b and 15c, which are surrounded from both sides, but also achieves high rigidity against bending stress generated in a direction oblique to the direction of extension of the first semi-cylindrical portion 15a and the second semi-cylindrical portions 15b and 15c, throughout the entire area of the top surface 7, the back wall 6, and the bottom surface 8.

[0115] In addition, if Figures 2 to 5A 、 Figure 5B As shown in the figures, the first half-cylinder portion 15a and the second half-cylinder portions 15b and 15c are formed integrally with the sealing portion 3, so that the bending stress generated in the lamp body 2 also acts on the front surface lens 4 through the sealing portion 3, thereby enabling further rigidity enhancement of the component support portion 16 to be achieved through both the lamp body 2 and the front surface lens.

[0116] In addition, if Figure 2 As shown, the first semi-cylindrical portion 15a is not limited to extending obliquely upward and leftward from the vicinity of the component support portion 16. The first semi-cylindrical portion 15a may be formed so as to be continuous with any one of the portions 7a of the sealing portion 3 on the top surface 7. Alternatively, as shown by the portion indicated by the reference numeral 15a' surrounded by an imaginary line (two-dot chain line), it may be formed directly above the component support portion 16. Furthermore, the second semi-cylindrical portions 15b and 15c may not be integrally formed with a single first semi-cylindrical portion 15a, but may instead be formed as a pair extending to the portion 7a of the sealing portion 3 on the top surface 7.

[0118] Next, use Figures 6 to 14 A second embodiment of the present disclosure will be described.

[0119] Figure 6 FIG. 2 is a schematic front view of a vehicle lamp 2001 according to a preferred embodiment of the present disclosure. The vehicle lamp 2001 is a headlamp installed at the left and right corners of the front of the vehicle. Figure 6 As shown, the vehicle lamp 2001 includes a container-shaped lamp body 2002 with a front opening and a front surface opening portion 2002' assembled to the lamp body 2002 (see the following description). Figure 7 The front cover 2004 is made of a light-transmitting resin such as polycarbonate or glass, and is attached to the front opening 2002' of the lamp body 2002 to define a lamp chamber S therein.

[0120] The divided lamp chamber S houses a high-beam lamp unit Hi and a low-beam lamp unit Lo. These are optical units configured to direct light emitted from a light source toward the front of the vehicle, producing high-beam and low-beam light distributions, respectively. Each lamp unit (Hi, Lo) can utilize a conventionally known structure, such as a reflector-type or projector-type lamp unit, and their type is not limited.

[0121] (Overall shape of the lamp body)

[0122] The shape of the lamp body 2002 will be described in detail. Figure 7 This is a schematic front view of the lamp body 2002.

[0123] The lamp body 2002 is formed by injection molding using a hard synthetic resin material. A sealing groove 2003 is provided around the periphery of the front opening 2002' of the lamp body 2002, which engages with a sealing leg provided on the periphery of the front cover 2004. Vehicle mounting portions 2005 for mounting to the vehicle body are provided protruding from the outer surface of the periphery of the front opening 2002' of the lamp body 2002, corresponding to the shape of the mounting portion on the vehicle body side. Vehicle mounting portions 2005 are provided at three locations on the outer surface of the lamp body 2002, along the top, and two locations on the left side, for a total of five locations.

[0124] The lamp body 2002 has a back wall 2006, a top surface 2007, a bottom surface 2008, and left and right side surfaces 2009 as constituent surfaces. The back wall 2006 bulges rearward and is continuously connected to the adjacent top surface 2007, bottom surface 2008, and side surfaces 2009 via ridge lines (curved lines).

[0125] Bottom surface 2008 extends forward from the lower edge of rear wall 2006 and connects to sealing groove 2003 provided at the edge of front opening 2002' of lamp body 2002. Side surfaces 2009 extend laterally and slightly forward from the left and right edges of rear wall 2006, respectively, and connect to sealing groove 2003. Top surface 2007 extends slightly, gently curving downward from the edge of sealing groove 2003 to connect to rear wall 2006, and is formed substantially integrally with rear wall 2006.

[0126] Therefore, the back wall 2006, the top surface 2007, the bottom surface 2008 and the side surface 2009 are not mainly flat surfaces, but are composed of curved surfaces with a large curvature radius, and the lamp body 2002 is formed as a whole into a container shape with the back wall 2006 as the bottom, and the back wall 2006, the top surface 2007, the bottom surface 2008 and the side surface 2009 respectively form container surfaces that are curved and smoothly continuous with each other.

[0127] The lamp body 2002 is formed with a first unit mounting hole 2031, a second unit mounting hole 2032, and a third unit mounting hole 2033. The first unit mounting hole 2031 is for mounting the high-beam lamp unit Hi and is formed in the upper left corner of the rear wall 2006. The second unit mounting hole 2032 is for mounting the rear cover (not shown) and is formed in the upper right corner of the rear wall 2006. The third unit mounting hole 2033 is for mounting the lamp driver module 2050 (described later, hereinafter referred to as LDM), which controls the lighting of the lamp units (Hi and Lo). It is formed in the lower center portion of the rear wall 2006.

[0128] In addition, a first calibration component mounting hole 2041, a second calibration component mounting hole 2042, and a third calibration component mounting hole 2043 are formed on the lamp body 2002 around the third unit mounting hole 2033. A calibration component (not shown) of an existing well-known structure is mounted in each of the calibration component mounting holes 2041, 2042, and 2043. The first calibration component mounting hole 2041 is provided at the lower edge of the left side of the back wall 2006 so as to be arranged between the third unit mounting hole 2033 and the first unit mounting hole 2031. The second calibration component mounting hole 2042 is provided at the lower edge of the right side of the back wall 2006 so as to be offset in the opposite direction of the first calibration component mounting hole 2041 at a distance substantially equal to the distance from the third unit mounting hole 2033 to the first calibration component mounting hole 2041. The third calibration component mounting hole 2043 is formed at the upper end of the right side of the back wall 2006 so as to be arranged substantially vertically above the second calibration component mounting hole 2042.

[0129] (Beam structure of the lamp body)

[0130] On the back wall 2006 of the lamp body 2002, a first beam 2061, a second beam 2062, a third beam 2063, a fourth beam 2064, a fifth beam 2065, a sixth beam 2066, and a seventh beam 2067, which are formed from a portion of the back wall 2006, extend over substantially the entire back wall 2006. The first beam 2061 connects the first calibration component mounting hole 2041 and the first unit mounting hole 2031 with the two as endpoints, forming a beam inclined to the left. The second beam 2062 extends substantially upward from the first calibration component mounting hole 2041 to the upper end of the back wall 2006, forming a beam extending in a substantially vertical direction. The third beam 2063 connects the first calibration component mounting hole 2041 and the upper center end of the back wall 2006 with the two as endpoints, forming a beam inclined to the right. The fourth beam 2064 extends from the upper center end of the back wall 2006 and the second calibration component mounting hole 2042 as endpoints, connecting the two and forming a beam inclined to the left. The fifth beam 2065 extends from the first calibration component mounting hole 2041 and the second calibration component mounting hole 2042 as endpoints, connecting the two and forming a beam extending in a generally horizontal direction. The sixth beam 2066 extends from the second calibration component mounting hole 2042 and the third calibration component mounting hole 2043 as endpoints, connecting the two and forming a beam extending in a generally vertical direction. The seventh beam 2067 extends from the second calibration component mounting hole 2042 and the second unit mounting hole 2032 as endpoints, connecting the two and forming a beam inclined to the right.

[0131] Figures 8A to 8G It is along Figure 7 End views of beams 2061-2067 along the cutting lines shown. Figure 8AIt is an end view along line AA, showing the cross-sectional shape of the first beam 2061 . Figure 8B BB is an end view taken along line BB, showing the cross-sectional shape of the second beam 2062 . Figure 8C It is an end view along the CC line, the upper portion shows the cross-sectional shape of the third beam 2063 , and the lower portion shows the cross-sectional shape of the left end portion of the fifth beam 2065 . Figure 8D It is an end view along the DD line, the upper portion shows the cross-sectional shape of the fourth beam 2064 , and the lower portion shows the cross-sectional shape of the right end portion of the fifth beam 2065 . Figure 8E EE is an end view taken along line EE, showing the cross-sectional shape of the sixth beam 2066 . Figure 8F FF is an end view taken along line FF, showing the cross-sectional shape of the seventh beam 2067 . Figure 8G This is an end view along line GG. The upper portion shows the cross-section of the fourth beam 2064, and the lower portion shows the cross-section of the central portion of the fifth beam 2065. A third unit mounting hole 2033 is formed in the central portion of the fifth beam 2065. Thus, the cross-section of each beam 2061-2067, perpendicular to its extension direction, is substantially arc-shaped. The curved surface of each beam 2061-2067 can project toward the lamp chamber S (forward) or outward (rearward). In this embodiment, each beam 2061-2067 is curved toward the lamp chamber S (forward).

[0132] Here, Figure 9 This is a front view of the lamp body 2002, in which the truss structure formed in the lamp body 2002 is shown in gray. As described above, since the top surface 2007 and the back wall 2006 are substantially integrally formed, the sealing groove 2003 of the top surface 2007 extends like the upper chord of the truss. In the lamp body 2002, the beams 2061 to 2067 are connected to the sealing groove 2003 of the top surface 2007 at the support point, thereby forming Figure 9 The truss structure shown.

[0133] Therefore, the lamp body 2002 of this embodiment has a structure with higher rigidity than a lamp body that does not have such a truss structure.

[0134] (Utilization of the structure inside the lamp)

[0135] The higher the rigidity of the truss structure, the thinner the lamp body 2002 can be compared with the past, and the lighter it can be. Figures 10 to 12 The construction used for this is described in detail.

[0136] Figure 10 yes Figure 7 The enlarged view of the H part, Figure 11 This is a diagram showing the configuration of LDM2050 in the H section. Figure 12 It is a bird's-eye view Figure 11 As shown in the figure. Figure 8C 、 Figure 8D and Figure 8G As shown, the fifth beam 2065 is composed of a curved surface convex toward the lamp chamber S direction (front), as shown in FIG. Figure 10 As shown, a third unit mounting hole 2033 is formed in the central portion of the fifth beam 2065. Figure 11 As shown, the LDM 2050 is fixed to the third unit mounting hole 2033 .

[0137] The LDM (write driver module) 2050 is one of the components within the lamp. In this specification, components within the lamp are those located within the lamp chamber S. These components, such as the lamp unit lighting control unit, the lamp unit rotation drive control unit, and the leveling drive control unit, are parts, components, or units that must be located within the lamp chamber S and have a specified size and strength.

[0138] The LDM2050 includes a lighting control circuit and an ECU (Electronic Control Unit) on a substrate (not shown), and a metal housing 2052 surrounding the substrate. The metal housing 2052 is rectangular in shape, and when fixed, the lower surface is slightly longer than the upper surface, with an open front. The back side of the metal housing 2052 serves as a connector insertion port 2054 (see Figure 12 The connector insertion opening 2054 has a shape corresponding to the concave and convex shape formed in the third unit mounting hole 2033 on its periphery and fits into the third unit mounting hole 2033. The LDM 2050 is supported by the fifth beam 2065 by fitting the connector insertion opening 2054 into the third unit mounting hole 2033.

[0139] Furthermore, fixing portions 2053 are integrally formed with the metal housing 2052 near the front end of the upper surface of the left and right side surfaces of the metal housing 2052. The fixing portions 2053 include: a first pressing plate 2531 formed by bending and offsetting a plate extending horizontally from the left and right side surfaces into a stepped shape; and a second pressing plate 2532 formed by bending the front of the first pressing plate 2531 vertically downward. At least the second pressing plate 2532 has a screw insertion hole (not shown).

[0140] On the left and right sides of the third unit mounting hole 2033, a pair of retaining arms 2081 and 2082 are formed to retain the LDM 2050. These retaining arms 2081 and 2082 are spaced apart across the left-right length of the LDM 2050 and are equidistant from the center of the third unit mounting hole 2033. These retaining arms 2081 and 2082 extend forward from the rear wall 2006 in a columnar shape, with their lower ends connected to the bottom surface 2008 and integrally formed therewith. The front surfaces 2083 of the retaining arms 2081 and 2082 are vertically flat and extend forward to a position aligned with the second pressing plate 2532 of the LDM 2050. These arms are provided with threaded holes 2084.

[0141] LDM2050 is cantilever supported on the fifth beam 2065 by embedding the connector insertion port 2054 into the third unit mounting hole 2033, and is fixed at three points by the third unit mounting hole 2033, the retaining arm 2081, and the retaining arm 2082 by threading the second pressing plate 532 of the fixing part 2053 to the front surface 2083 of the retaining arms 2081 and 2082.

[0142] (Effect)

[0143] Conventionally, based on the assumption that internal lamp structures like the LDM only need to be installed somewhere within the lamp body, they are often placed in unused space within the lamp body, such as by creating a box-shaped housing to support the LDM housing. In contrast, in this embodiment, the LDM 2050 (internal lamp structure) is supported by the fifth beam 2065 (truss structure) of the lamp body 2. Consequently, the rigidity of the LDM 2050 (internal lamp structure) becomes part of the rigidity of the fifth beam 2065, thereby reinforcing the strength of the fifth beam 2065.

[0144] In particular, in the truss structure formed in the lamp body 2 of this embodiment, the fifth beam 2065 of the beams 2061 to 2067 serves as a compression member, and therefore preferably has higher rigidity. In this embodiment, the rigidity of the LDM 2050 serves as a portion of the rigidity of the fifth beam 2065, thereby increasing the rigidity of the compression member of the truss structure. This improves the resistance of the truss structure formed in the lamp body 2002 to deformation and buckling.

[0145] Furthermore, by extending the internal structure of the lamp along the axial direction of the beam, the rigidity of the beam can be made dependent on the rigidity of the internal structure of the lamp, which is preferable. Therefore, in this embodiment, when the metal shell 2052 of the LDM 2050 is fixed, the horizontal direction is longest among the left-right, front-back, and up-down directions. The long side of the metal shell 2052 is arranged in the horizontal direction, which serves as the axial direction of the fifth beam 2065. Therefore, the LDM 2050 functions as a column within the fifth beam 2065, further enhancing the rigidity of the truss structure formed in the lamp body 2002.

[0146] Furthermore, the internal structure of the lamp is also connected to a container surface other than the container surface with the beam supporting the internal structure. This allows the rigidity of the beam supporting the internal structure to also rely on the rigidity of the other container surface, which is preferable. Therefore, in this embodiment, the LDM 2050 is fixed at three points: not only to the back wall 2006 (the container surface) with the fifth beam 2065 supporting the LDM 2050, but also to the retaining arms 2081 and 2082 formed on the bottom surface 2008 (the other container surface) adjacent thereto. Consequently, the rigidity of the fifth beam 2065 is reinforced by the rigidity of the bottom surface 2008. This enhanced rigidity of the fifth beam 2065 further improves the resistance to deformation and buckling of the truss structure formed in the lamp body 2002.

[0147] (Variation)

[0148] Next, preferred modified examples of the above-described embodiment will be described.

[0149] Figure 13 A vehicle lamp 2110 showing a first modified example is a lamp 2110 and a Figure 10Similarly enlarged. The fifth beam 2065, on which the LDM 2050 is mounted, is a relatively long beam compared to the other beams 2061-2064 and 2066-2067. Preferably, a lamp internal structure is mounted on such a long beam, as described in the embodiment, and as shown in this variation, at least one undulation is formed in the longitudinal direction of the lamp internal structure on the container surface near the beam to disperse the stress applied to the beam supporting the lamp internal structure. In this variation, a reinforcing rib 2080 is formed on the bottom surface 2008 (container surface) located near the fifth beam 2065. The reinforcing rib 2080 extends from the back wall 2006 to the sealing groove 2003 approximately in the center below the LDM 2050. The lower end of the reinforcing rib 2080 is connected to the bottom surface 2008, forming an integral part of the bottom surface 2008. The rib 2080 forms a undulation on the bottom surface 2008 (the container surface) near the fifth beam 2065, in the left-right direction, which is the longitudinal direction of the LDM 2050 (the internal structure of the lamp). This flexure of the rib 2080 disperses the stress transmitted from the bottom surface 2008 to the fifth beam 20065, resulting in a structure that improves the surface strength of the fifth beam 2065. This enhances the rigidity of the fifth beam 2065, further improving its resistance to deformation and buckling of the truss structure formed in the lamp body 2002. It should be noted that the rib 2080 can be curved in either the direction of the lamp chamber S (upward) or outward (downward). The number of undulations is not limited to one; multiple undulations may also be provided.

[0150] Figure 14 is a diagram showing two modified examples of vehicle lamps 2120, which are similar to Figure 7Similarly, the figure of the lamp 2120 is observed from the front. In the truss structure formed in the lamp body 2002 of the embodiment, the sixth beam 2066 among the beams 2061 to 2067 also becomes a compression member. Therefore, the sixth beam 2066 is also preferably provided with high rigidity in order to prevent deformation and buckling. Therefore, in this modification, a calibration drive module 2090 is arranged on the sixth beam 2066 having the third calibration component mounting hole 2043. The calibration component driven and controlled by the calibration component module 2090 can be a conventionally known structure, connecting the calibration screw 2102 (or calibration rod) arranged in the third calibration component mounting hole 2043 to the lamp bracket 2101 (indicated by a dotted line) supporting the lamp unit (Hi, Lo). The calibration drive module 2090 has a driving mechanism and a control unit (not shown) for moving the calibration screw 2102 in the front-back direction, and a metal shell 2092 for accommodating the driving mechanism and the control unit. The metal shell 2092 is fixed to the sixth beam 2066 by, for example, upper and lower fixing portions 2093, screwing the long strip of the shell in a vertical direction that becomes the axial direction of the sixth beam 2066. In this way, in particular, the beam that becomes the compression member of the truss structure can further improve the rigidity of the truss structure of the lamp body 2002 by actively supporting the internal structure of the lamp, and accordingly, the lamp body 2002 can be made thinner and lighter. In addition, in the embodiment, the outer shape of the internal structure of the lamp is also described as a metal shell, but the material of the shell can also be, for example, resin, and is not limited to a rectangular parallelepiped shape. Even if the outer shape of the internal structure of the lamp is a shape that deviates from the shape of the shell, as long as the structure has a size and strength that can reinforce the beam, the outer shape can be appropriately deformed.

[0151] While the preferred embodiments of the present disclosure have been described above, these embodiments are merely examples of the present disclosure. Combinations of these embodiments are possible based on the knowledge of those skilled in the art, and such combinations are also within the scope of the present disclosure. In particular, the directions and configurations of the beams disclosed in this specification are merely examples; other truss structures can also be used as long as a triangular truss structure is formed. Accordingly, the configuration of the internal components of the lamp disclosed in this specification is merely an example, and the configuration of the internal components of the lamp can be appropriately modified based on the truss structure formed on the lamp body.

[0152] (Vehicle lighting)

[0153] Next, use Figures 15 to 22 A second embodiment of the present disclosure will be described.

[0154] Figure 15 FIG. 3 is a schematic front view of a vehicle lamp 3001 according to a preferred embodiment of the present disclosure. The vehicle lamp 3001 is a headlamp installed at the left and right corners of the front of the vehicle. Figure 15As shown, a vehicle lamp 3001 includes a container-shaped lamp body 3002 having a front opening 3002′, and a front cover 3004 assembled to the front opening 3002′ of the lamp body 3002. The front cover 3004 is made of, for example, a light-transmitting resin such as polycarbonate or glass. By attaching the front cover 3004 to the front opening 3002′ of the lamp body 3002, a lamp chamber S is defined inside.

[0155] The divided lamp chamber S houses a high-beam lamp unit Hi and a low-beam lamp unit Lo. These are optical units configured to direct light emitted from a light source toward the front of the vehicle, creating high-beam and low-beam light distributions. Each lamp unit (Hi, Lo) can utilize conventionally known structures, such as reflector-type or projector-type lamp units, and their types are not limited.

[0156] (Overall shape of the lamp body)

[0157] The shape of the lamp body 3002 will be described in detail. Figure 16 This is a schematic front view of the lamp body 3002.

[0158] The lamp body 3002 is formed by injection molding using a hard synthetic resin material. Sealing grooves 3003 are provided around the periphery of the front opening 3002′ of the lamp body 3002, which engage with sealing legs provided on the periphery of the front cover 3004. Vehicle mounting portions 3005 for attaching the vehicle lamp 3001 to the vehicle body are protruding from the outer surface of the periphery of the front opening 3002′ of the lamp body 3002, corresponding to the shape of the mounting portion on the vehicle body. The vehicle mounting portions 3005 are provided at three locations on the outer surface of the lamp body 3002, along the top, and two locations on the left, for a total of five locations.

[0159] The lamp body 3002 comprises a back wall 3006, a top surface 3007, a bottom surface 3008, and left and right side surfaces 3009. The back wall 3006 bulges rearward, connecting to the adjacent top surface 3007, bottom surface 3008, and side surfaces 3009 in a continuous, curved manner via ridgelines. Furthermore, the top surface 3007, bottom surface 3008, and side surfaces 3009 are generally convexly curved, gently bulging outward from the lamp body 3002. They curve gently at their edges, connecting continuously without any bends or steps. Consequently, the lamp body 3002 is formed as a whole into a container-like shape with rounded corners.

[0160] The bottom surface 3008 extends forward from the lower edge of the rear wall 3006 and is connected to the sealing groove 3003 provided at the edge of the front opening 3002' of the lamp body 3002. The side surfaces 3009 extend laterally and slightly forward from the left and right edges of the rear wall 3006 and are connected to the sealing groove 3003. The top surface 3007 extends slightly, gently curving rearward and downward from the edge of the sealing groove 3003 and extending to connect to the rear wall 3006, forming a substantially integral body with the rear wall 3006.

[0161] Therefore, the back wall 3006, the top surface 3007, the bottom surface 3008 and the side surface 3009 are mainly composed of curved surfaces with a large curvature radius rather than flat surfaces, and the lamp body 3002 as a whole is formed into a container shape with the back wall 3006 as the bottom, and the back wall 3006, the top surface 3007, the bottom surface 3008 and the side surface 3009 respectively form container surfaces whose curved surfaces are smoothly continuous with each other.

[0162] The lamp body 3002 is formed with a first unit mounting hole 3031, a second unit mounting hole 3032, and a third unit mounting hole 3033. The first unit mounting hole 3031 is for mounting the low-beam lamp unit Lo and is formed in the upper left corner of the rear wall 3006. The second unit mounting hole 3032 is for mounting the rear cover (not shown) and is formed in the upper right corner of the rear wall 3006. The third unit mounting hole 3033 is for mounting a lamp driver module (not shown) that controls the lighting of the lamp units (Hi and Lo) and is formed approximately in the center of the lower portion of the rear wall 3006.

[0163] Furthermore, lamp body 3002 includes a first calibration member mounting hole 3041, a second calibration member mounting hole 3042, and a third calibration member mounting hole 3043 formed around third unit mounting hole 3033. A calibration member (not shown) of a conventionally known structure is mounted in each of calibration member mounting holes 3041, 3042, and 3043.

[0164] The first calibration component mounting hole 3041 is provided at the lower edge of the back wall 3006, positioned between the first unit mounting hole 3031 and the third unit mounting hole 3033. The second calibration component mounting hole 3042 is provided at the right lower edge of the back wall 3006, offset in the opposite direction from the first calibration component mounting hole 3041 by a distance substantially equal to the distance from the third unit mounting hole 3033 to the first calibration component mounting hole 3041. The third calibration component mounting hole 3043 is provided at the right upper end of the back wall 3006, positioned substantially vertically above the second calibration component mounting hole 3042.

[0165] (Back wall and beam)

[0166] On rear wall 3006, first beam 3061, second beam 3062, third beam 3063, fourth beam 3064, fifth beam 3065, and sixth beam 3066, which constitute a portion of rear wall 3006, extend from the upper end to the lower end of rear wall 3006. The portion of rear wall 3006 other than beams 3061 to 3066 is referred to as rear wall body 3069.

[0167] The first beam 3061 extends to connect the first alignment member mounting hole 3041 at the lower left of the back wall 3006 and the first unit mounting hole 3031 at the upper end.

[0168] The second beam 3062 extends straightly upward from the first calibration component mounting hole 3041 at the lower left of the back wall 3006 to the upper end of the back wall 3006 when viewed from the front.

[0169] The third beam 3063 extends from the first alignment member mounting hole 3041 at the lower left of the rear wall 3006 toward the upper right to the upper end of the rear wall 3006. Therefore, the third beam 3063 is formed to be inclined to the right when viewed from the front.

[0170] The fourth beam 3064 extends from the second alignment member mounting hole 3042 at the lower right side of the rear wall 3006 toward the upper left to the upper end of the rear wall 3006. Therefore, the fourth beam 3064 is formed to be inclined to the left when viewed from the front.

[0171] The fifth beam 3065 extends to connect the second calibration component mounting hole 3042 at the lower right side of the back wall 3006 and the third calibration component mounting hole 3043 at the upper side. Therefore, the fifth beam 3065 extends straight upward to the upper end of the back wall 3006 when viewed from the front.

[0172] The sixth beam 3066 extends from the second alignment member mounting hole 3042 at the lower right side of the back wall 3006 and the second unit mounting hole 3032 at the upper side thereof, connecting the two.

[0173] Figures 17A to 17F It is along Figure 16 The cut lines are end views of the beams 3061 to 3066 shown. Figure 17A It is along Figure 16 The end view C along line AA mainly shows the cross-sectional shape of the first beam 3061 . Figure 17B It is along Figure 16 The end view along line BB mainly shows the cross-sectional shape of the second beam 3062 . Figure 17C It is along Figure 16 The end view of the CC line mainly shows the cross-sectional shape of the third beam 3063. Figure 17D It is along Figure 16 The end view along line DD mainly shows the cross-sectional shape of the fourth beam 3064. Figure 17E It is along Figure 16 The end view along line EE mainly shows the cross-sectional shape of the fifth beam 3065 . Figure 17F It is along Figure 16 The end view of the FF line mainly shows the cross-sectional shape of the sixth beam 3066.

[0174] like Figures 17A to 17F As shown, the cross-sectional shape of each beam 3061-3066 perpendicular to its extension direction varies in curvature radius, width, and projection, but is generally arc-shaped. The curved surface of each beam 3061-3066 can project in either the direction toward the lamp chamber S (forward) or outward (rearward). In this embodiment, each beam 3061-3066 is curved toward the lamp chamber S (forward). This cross-sectional shape of the lamp body 3002 maintains a constant wall thickness, lacks curved portions, and is continuous.

[0175] Figure 18 FIG3 is a front view of the lamp body 3002, in which the beams 3061 to 3066 are represented in gray. Figure 18 As shown, each beam 3061-3066 extends from the upper end to the lower end of the back wall 3006, with other beams extending obliquely from the ends of certain beams, forming a truss structure with triangular units. The thick-walled sealing groove 3003 is incorporated into the truss structure. Consequently, the lamp body 3002, including the back wall 3006, is resistant to deformation under load. Furthermore, since the beams 3061-3066 themselves are curved surfaces with a roughly arc-shaped cross-section that disperses stress, the structure is highly rigid and resistant to deformation.

[0176] Therefore, the lamp body 3002 of this embodiment has a structure with higher rigidity than a lamp body without such a truss structure. By improving the rigidity of the lamp body 3002, it is possible to achieve a thinner wall than before.

[0177] (petal structure)

[0178] Not limited to the above structure, by forming at least a portion of the surface of the lamp body 3002 with a curved surface, flexural rigidity can be increased. Furthermore, by increasing the rigidity of the lamp body 3002, reinforcing ribs are no longer necessary, thereby achieving lightweight design. As an example, the structure surrounding the opening of the lamp body 3002, namely the third unit mounting hole 3033, will be described.

[0179] Figures 19 to 21 yes Figure 16 The H portion of the lamp body 3002 is shown. Figure 19 This is the back C picture of the H part. Figure 20 This is a perspective view of the back of the H section. Figure 21 This is the plan C diagram of section H.

[0180] The third unit mounting hole 3033 is located approximately in the center of the lower portion of the back wall 3006 of the lamp body 3002 and is formed into a rectangular shape consisting of an upper side 3071, a lower side 3072, a left side 3073, and a right side 3074. Each side 3071-3074 is a curved line with a central portion bulging outward, and the connecting portions (corners) of each side 3071-3074 are also arc-shaped, resulting in a rounded shape for the third unit mounting hole 3033 as a whole.

[0181] A cylindrical fitting portion 3080 is provided around the periphery of the third unit mounting hole 3033 to engage and stably support the lamp driver module (not shown). The fitting portion 3080 extends from the outer surface of the back wall 3006 and has an inner hole that mirrors the shape of the third unit mounting hole 3033. The fitting portion (not shown) of the lamp driver module is inserted into the fitting portion 3080, thereby mounting the lamp driver module in the third unit mounting hole 3033.

[0182] As described above, the entire lamp body 3002 is primarily composed of curved surfaces. The area (H) roughly in the lower center of the back wall 3006, where the third unit mounting hole 3033 is located, centered around the third unit mounting hole 3033, is also essentially composed of a curved surface that bulges significantly outward and has a large radius of curvature. Furthermore, by forming a concave or convex portion in this area, the rigidity of the lamp body 3002 in this area is further enhanced.

[0183] In the rear wall 3006 , a plurality of recessed portions or projecting portions are formed in a peripheral region around the third unit mounting hole 3033 so as to surround the third unit mounting hole 3033 .

[0184] Specifically, a first convex portion 3091 is formed above the upper side 3071, protruding rearward. A second convex portion 3092 is formed near the left side of the left side 3073, protruding rearward. Similarly, a third convex portion 3093 is formed near the right side of the right side 3074, protruding rearward. The back wall 3006 is formed to have a substantially constant thickness, and each of the convex portions 3091-3093 has a hollow, generally convex hemispherical shape that protrudes rearward.

[0185] The protrusions 3091 to 3093 are formed in an annular shape around the third unit mounting hole 3033 so as to surround the third unit mounting hole 3033 . The peripheral area of the third unit mounting hole 3033 of the lamp body 3002 is roughly in the shape of a petal with the protrusions 3091 to 3093 as petals.

[0186] Figure 22 It is along Figure 19 The JJ line passes through the third protrusion 3093, the third unit mounting hole 3033, and the second protrusion 3092.

[0187] like Figure 22 As shown, the convex portions 3091 to 3093 are formed of curved surfaces, and their boundaries are smoothly connected via ridge lines, and the rear wall 3006 is continuously formed without any curved portion.

[0188] The third convex portion 3093 , the third unit mounting hole 3033 , and the second convex portion 3092 form a horizontal cross-sectional shape of the back wall 3006 passing through the third unit mounting hole 3033 into a wave shape with continuous concavities and convexities.

[0189] By providing a continuously concave-convex cross-sectional area in at least a portion of the lamp body 3002, the moment of inertia of the area can be increased, resulting in a structure with strong bending stress. This improves the rigidity of the lamp body 3002. This structure eliminates the need for reinforcing ribs in the area surrounding the third unit mounting hole 3033 of the lamp body 3002, maintaining the same level of rigidity as conventional designs even with a thinner wall.

[0190] The number of convex portions of the petals forming the petal shape is not specified, and the number can be further increased based on this structure. Furthermore, in this embodiment, the petal shape of the petals is convex, but it can also be concave, or a mixture of convex and concave shapes. Since the petal structure is provided on the back wall 3006, when viewed from the back, the convex portions become concave portions, and the concave portions become convex portions. Therefore, regardless of whether the petal shape is concave or convex, it forms a curved surface provided on the back wall 3006, thereby increasing the cross-sectional moment of inertia of the back wall 3006.

[0191] The third unit mounting hole 3033 is an opening, or a through-hole, forming a cutout in the lamp body 3002, resulting in lower rigidity than other areas. The third unit mounting hole 3033 is a mounting hole for inserting and engaging lamp components, and therefore requires higher rigidity. Therefore, by forming a petal-shaped shape centered around the third unit mounting hole 3033, the rigidity of the area surrounding the weaker opening in the back wall 3006 is increased. Providing an opening at the center of the petal-shaped shape, and thus a mounting hole for the lamp component, improves the rigidity of the lamp body 3002 centered around the weaker hole, making this a preferred method. In this embodiment, the third unit mounting hole is a mounting hole for the lamp driver module, and serves as a connector hole for the lamp driver module. However, this is not limiting. The opening also includes mounting or engaging holes for components such as socket lamps, back covers, and actuators, insertion holes for cables or ground wires, access holes for attaching and detaching components, and windows for air or moisture.

[0192] The shape of the opening in the center of the petal shape is not limited to a substantially rectangular shape, and may be circular or polygonal.

[0193] The center of the petal shape is not limited to an opening; it can also be a convex or concave portion, or even a portion with nothing formed on it. By forming the convex and concave portions of the petals, the moment of inertia of the area where the petal shape is formed is increased, thereby improving the rigidity of the lamp body 3002. Furthermore, the area where the petal shape is formed is not limited to the back wall 3006; it can also be located on the bottom surface 3008, the top surface 3007, or the left and right side surfaces 3009.

[0194] The convex and concave portions of the petals constituting the petal shape are preferably arranged evenly in the circumferential direction relative to the hole or concave and convex portion forming the center of the petal shape. In addition, if they are arranged in pairs relative to each other, the load distribution balance is well achieved, which is more preferred.

[0195] In addition, if Figure 19 As shown, a first recess 3099 is formed below the lower edge 3072 of the third unit mounting hole 3033. A portion of the first recess 3099 engages with the bottom surface 3008. The recess toward the lower edge 3072 extends in the front-to-back direction, and the bottom surface 3008 is also recessed, forming a groove-like recess that is recessed in the vertical direction and extends in the front-to-back direction. The first recess 3099 forms one of the petals of a petal-shaped structure centered on the third unit mounting hole 3033.

[0196] First recess 3099 forms a complex, three-dimensional pattern of projections and recesses in the rear wall 3006, centered around third unit mounting hole 3033. Each of projections 3091-3093 and recess 3099 is smoothly continuous, connected by a substantially constant thickness without any bends, and has a wavy cross-sectional shape.

[0197] In this embodiment, if Figures 19 to 22 As shown, the back wall 3006 in the area surrounding the third unit mounting hole 3033 is recessed toward the third unit mounting hole 3033, forming an annular recess 3085 with the third unit mounting hole 3033 as the bottom and centered around the third unit mounting hole 3033 and the fitting portion 3080. In other words, the back wall 3006 in the area surrounding the third unit mounting hole 3033 gently protrudes forward with the third unit mounting hole 3033 as the center, and the third unit mounting hole 3033 is formed in the center of the protrusion.

[0198] An annular projection 3086 is formed on the radially outer side of the annular recess 3085 so as to surround the annular recess 3085 and annularly protrude rearward with the third unit mounting hole 3033 as the center.

[0199] The annular convex portion 3086 includes the aforementioned first convex portion 3091, second convex portion 3092, third convex portion 3093, and first concave portion 3099, which serve as a convex portion one step higher and a concave portion one step lower than the annular convex portion 3086. Concave portions are formed between the separately formed convex portions 3091-3093, forming an annular concave-convex portion with repeated concave-convex patterns centered around the third unit mounting hole 3033. In this embodiment, the third unit mounting hole 3033 is provided at the lower portion of the back wall 3006, and the first concave portion 3099 engages with the bottom surface 3008. Therefore, a portion of the annular concave-convex portion also extends over the bottom surface 3008.

[0200] These convex and concave portions create a complex, three-dimensional pattern of projections and recesses in the area around the third unit mounting hole 3033 on the back wall 3006. Each of the convex portions 3091-3093 and the concave portion 3099 smoothly connects along ridgelines, with a substantially constant wall thickness and no bends, resulting in a wavy cross-sectional shape. In the area around the third unit mounting hole 3033 on the back wall 3006, the moment of inertia increases in both the front-to-back and vertical directions, improving the rigidity of the lamp body 3002 in the area centered on the third unit mounting hole 3033.

[0201] The annular convex portion 3086 and the annular concave portion 3085 make the concave-convex shape complicated. However, even if the annular convex portion 3086 and the annular concave portion 3085 are not provided, there is no problem in forming only the convex portions 3091 to 3093 centered on the third unit mounting hole 3033 .

[0202] like Figures 19 to 21As shown, a fourth protrusion 3094 is formed further to the left of the second protrusion 3092 provided to the left of the left side 3073. The fourth protrusion 3094 is formed separately from the second protrusion 3092, and a concave portion is formed between the second protrusion 3092 and the fourth protrusion 3094.

[0203] Similarly, a fifth protrusion 3095 is formed further to the right of the third protrusion 3093 provided to the right of the right side 3074. The fifth protrusion 3095 is formed separately from the third protrusion 3093, and a facing recess is formed between the third protrusion 3093 and the fifth protrusion 3095.

[0204] The fourth convex portion 3094 and the fifth convex portion 3095 have the same structure as the convex portions 3091 to 3093 and have a hollow convex hemispherical shape that convexes toward the rear.

[0205] The fifth convex portion 3095, the third convex portion 3093, the second convex portion 3092, and the fourth convex portion 3094 are formed continuously in the horizontal direction. Figure 22 As shown, these protrusions 3091, 3092, 3094, and 3095 further form a continuous wave in a horizontal cross-sectional view around the third unit mounting hole 3033. This is preferable if the protrusion or recess (the first petal) of the petal that forms the petal shape is further radially outwardly formed with another protrusion or recess (the second petal) when viewed from the center of the petal shape. This increases the number of curved surfaces around the third unit mounting hole 3033, further improving the rigidity of the lamp body 3002. More preferably, multiple protrusions or recesses are arranged linearly along a certain radial direction from the third unit mounting hole 3033, as in the fifth protrusion 3095 and the third protrusion 3093, and the second protrusion 3092 and the fourth protrusion 3094.

[0206] Without limitation thereto, another convex portion or concave portion may be formed, for example, between the first convex portion 3091 and the second convex portion 3092 in the circumferential direction at a position farther from the third unit mounting hole 3033 than the first convex portion 3091 and the second convex portion 3092 in the radial direction.

[0207] Preferred embodiments of the present disclosure have been described above, but the above embodiments are merely examples of the present disclosure, and they can be combined based on the knowledge of those skilled in the art, and such forms are also included in the scope of the present disclosure.

[0208] Next, use Figures 23 to 29C A second embodiment of the present disclosure will be described.

[0209] Figure 23 A front view of a vehicle lamp 4001 according to a preferred embodiment of the present disclosure is shown. Figure 23 The vehicle lamp 4001 includes a lamp body 4002, a front lens 4004, and a plurality of brackets 4005 for mounting the lamp body 4002 on the vehicle body. The lamp body 4002 is formed of a resin or the like, and in a vertical cross-section along the front-to-back direction, has a container shape with a back wall extending vertically and a bottom wall extending front and back, and has an opening at its front end. A sealing portion 4003, recessed in a rearward groove, as shown by reference numeral 4003 in the respective figures, is provided around the front opening of the lamp body 4002. The front lens 4004 is formed of a light-transmitting resin or glass or the like, and is fixed to the sealing portion 4003, thereby defining a sealed lamp chamber S inside the lamp body 4002.

[0210] exist Figure 23 The compartmentalized lamp chamber S shown houses a high-beam lamp unit Hi and a low-beam lamp unit Lo, which illuminate headlights forward (toward the front of the drawing). The high-beam lamp unit Hi and the low-beam lamp unit Lo are optical units configured to direct light emitted from a light source toward the front of the vehicle, creating high-beam and low-beam light distributions. Each lamp unit (Hi, Lo) can employ conventionally known structures, such as reflector-type or projector-type lamp units, and their types are not limited.

[0211] Next, the shape of the lamp body 4002 will be described in detail. Figure 24 This is a schematic front view of the lamp body 4002. The lamp body 4002 is formed by injection molding using a hard synthetic resin material. The lamp body 4002 has a back wall 4006, a top surface 4007, a bottom surface 4008, and left and right side surfaces 4009 as its constituent surfaces. The back wall 4006 bulges outward and is connected to the adjacent top surface 4007, bottom surface 4008, and side surfaces 4009 in a curved continuous manner via ridges. In addition, the top surface 4007, bottom surface 4008, and side surfaces 4009 basically form a convex curved shape that bulges gently toward the outside of the lamp body 4002, and are gently curved at their edges, continuously connected without bends or steps. Therefore, the lamp body 4002 is formed as a whole in the shape of a container with rounded corners.

[0212] Figure 24The bottom surface 4008 shown extends forward from the lower edge of the back wall 4006 and is connected to the sealing portion 4003 provided at the edge of the front opening of the lamp body 4002. Side surfaces 4009 extend laterally and slightly forward from the left and right edges of the back wall 4006, respectively, and are connected to the sealing portion 4003. The top surface 4007 extends slightly, gently curving downward and rearward from the edge of the sealing portion 4003 and extending to connect to the back wall 4006, forming a substantially integral part with the back wall 4006. Therefore, the back wall 4006, top surface 4007, bottom surface 4008, and side surfaces 4012 are not primarily flat surfaces, but rather are formed of curved surfaces with a large radius of curvature. The lamp body 4002 is formed as a whole into a container shape with the back wall 4006 as the bottom. The back wall 4006, top surface 4007, bottom surface 4008, and side surfaces 4012 each form a container surface whose curved surfaces smoothly continue from one another.

[0213] In addition, if Figure 24 As shown in the area indicated by the reference numeral H1, the back wall 4006 of the lamp body 4002 is provided with: three protrusions 4009a to 4009c, which are installed as a pair Figure 23 An alignment actuator 4010 of a lamp component of an alignment mechanism for adjusting the orientation of each lamp unit (Hi, Lo); and three fixing parts 4011 of an alignment bracket (not shown).

[0214] according to Figure 25A 、 Figure 25B and Figure 26A 、 Figure 26B , explaining the three protrusions 4009a to 9c of the lamp body 4002. The three protrusions are composed of a first protrusion 4009a, a second protrusion 4009b, and a third protrusion 4009c. Figure 27A 、 Figure 27B As shown, the base ends 4009a2, 4009b2, 4009c2 of the protrusions 4009a, 4009b, 4009c are directed toward Figure 23 The outside of the lamp chamber S, that is, the rear of the lamp body 4002, is open, and each of the front end portions 4009a1, 4009b1, and 4009c1 is closed and has a bottomed cylindrical shape that protrudes toward the inside of the lamp chamber S. Furthermore, each of the front end portions 4009a1, 4009b1, and 4009c1 is formed in a hemispherical shape, and a flat portion 4009c3 is provided on the top of the front end portion 4009c3 of the third protrusion 4009c.

[0215] like Figure 25B 、 Figure 26B and Figure 27B As shown in FIG. 4 , the calibration actuator 4010 is positioned left and right in a state where the left side 4010a and the right side 4010b are clamped by the first protrusion 4009a and the second protrusion 4009b, respectively. Figure 27A As shown, the calibration actuator 4010 is positioned rearward with its rear surface 4010c in contact with the flat portion 4009c3 of the top portion 4009c1 of the third protrusion 4009c. The calibration actuator 4010 is held from the front by an actuator bracket (not shown) fixed to the three fixing portions 4011 by screws or the like.

[0216] Figure 25B 、 Figure 26B and Figure 27A 、 Figure 27B The illustrated aiming actuator 4010 is fixed to the lamp body 4002 in a state where it is sandwiched left and right by the first protrusion 4009a and the second protrusion 4009b and sandwiched front and back by the actuator bracket (not shown) and the third protrusion 4009c.

[0217] First, to Figure 23 The lamp chamber S shown in FIG. 1 shows multiple bottomed cylindrical protrusions 4009a to 4009c integrally formed with the lamp body 4002. These protrusions extend from a portion of the back wall 4006 of the lamp body 4002 to form a hollow shape. This reduces weight and improves the rigidity of the lamp body 4002 against bending stress. Furthermore, the multiple protrusions 4009a to 4009c are formed to contact the outer periphery of the alignment actuator 4010, a lamp component, thereby restricting movement in the contact direction and positioning the alignment actuator 4010 relative to the lamp body 4002. The multiple protrusions 4009a to 4009c ensure sufficient rigidity in the lamp body 4002 even without ribs, thereby reducing the weight of the lamp body 4002 and the vehicle lamp 4001. Furthermore, by forming the protrusions 4009 a to 4009 c so as to contact the aiming actuator 4010 as a lamp component, positioning relative to the lamp body 4002 can be performed with a simple structure.

[0218] in addition, Figure 25B and Figure 26B The illustrated alignment actuator 4010 is guided to a predetermined position in the left-right direction along the hemispherical surface by contacting the hemispherical top portions 4009a1 and 4009b1 and being inserted between the first protrusion 4009a and the second protrusion 4009b. Furthermore, in this embodiment, the left and right side surfaces 4010a and 4010b of the alignment actuator 4010, which is a lamp component, are held from both left and right directions by a pair of first protrusions 4009a and second protrusions 4009b. However, the lamp component is not limited to being held from two directions and may also be held from three or more directions by three or more protrusions arranged to contact the outer side surfaces.

[0219] In addition, if Figure 26B and Figure 27B As shown, the alignment actuator 4010 is held by the third protrusion 4009c via the rear surface 4010c, thereby maintaining the lamp component separated from the back wall 4006 of the lamp body 4002. As a result, even if the back wall 4006 is formed in an oblique or wavy shape, the alignment actuator 4010 can be positioned and held in a predetermined direction without tilting based on the back wall 4006. Furthermore, the alignment actuator 4010 is held by the top portion 4009c1 of the third protrusion 4009c in contact with the flat portion 4009c3 having a surface extending along the top and bottom, thereby maintaining a stable state that is less prone to tilting up, down, left, or right than when held by a hemispherical surface.

[0220] In addition, if Figure 24 and Figure 28A 、 Figure 28B As shown, in the area indicated by reference numeral H2, a rear wall 4006 of the lamp body 4002 is provided with a rotation position-based Figure 23 Mounting holes 4024 are provided for adjusting screws 4025 for adjusting the orientation of each lamp unit (Hi, Lo). A pair of left and right fourth protrusions 4021a and fifth protrusions 4021b are provided above mounting holes 4024. Sixth and seventh protrusions 4023a and 4023b are provided on the fourth and fifth protrusions 4021a, 4021b, respectively, extending toward mounting holes 4024.

[0221] like Figure 28A 、 Figure 28B and Figure 29B As shown, the fourth protrusion 4021a and the fifth protrusion 4021b have a bottomed cylindrical shape, and the base ends 4021a1 and 4021b1 of each protrusion face Figure 23 The inner side of the lamp chamber S, that is, the front of the lamp body 4002 is open, and each front end is closed and protrudes toward the outside of the lamp chamber S. Figure 28A 、 Figure 28B and Figure 29C As shown, the sixth protrusion 4023a and the seventh protrusion 4023b have a bottomed cylindrical shape, and the base ends 4023a1 and 4023b1 of each protrusion face Figure 23 The inner side of the lamp chamber S, that is, the front side of the lamp body 4002, is open, and each front end is closed and protrudes outward from the lamp chamber S. Furthermore, the sixth protrusion 4023a and the seventh protrusion 4023b are formed continuously with the fourth protrusion 4021a and the fifth protrusion 4021b, respectively, and are formed in an elongated shape so as to be parallel to each other toward the mounting hole 4024. Furthermore, the fourth protrusion 4021a and the fifth protrusion 4021b are each formed so as to protrude higher than the sixth protrusion 4023a and the seventh protrusion 4023b.

[0222] Figure 28B The adjustment screw 4025 shown is rotated by the lamp component, i.e., the adjustment driver 4020, which is inserted from above. Figure 28A 、 Figure 28B and Figure 29B As shown, the fourth protrusion 4021a and the fifth protrusion 4021b are formed on the lamp body 4002 in a manner having a substantially same interval as the diameter of the adjustment driver 4020. Figure 28A 、 Figure 28B and Figure 29C As shown, the sixth protrusion 4023 a and the seventh protrusion 4023 b are also formed on the lamp body 4002 with a spacing substantially the same as the diameter of the adjustment driver 4020 .

[0223] like Figure 28B As shown, the adjustment actuator 4020 is positioned left and right relative to the adjustment screw 4025 by being inserted between the fourth protrusion 4021a and the fifth protrusion 4021b, which are arranged at a distance substantially equal to the diameter of the adjustment screw 4025. Furthermore, the adjustment screw actuator 4020 is inserted between the sixth protrusion 4023a and the seventh protrusion 4023b, which extend from the fourth protrusion 4021a and the fifth protrusion 4021b to the vicinity of the mounting hole 4024 of the adjustment screw 4025, thereby accurately guiding the tip 4020a of the adjustment screw actuator 4020 to the engaging portion of the adjustment screw 4025.

[0224] In addition, if Figure 28B and Figure 29B As shown, the front ends of the fourth protrusion 4021a and the fifth protrusion 4021b are both formed into a hemispherical shape. Figure 28B and Figure 29C As shown, the sixth protrusion 4023a and the seventh protrusion 4023b are formed to have a semi-cylindrical shape in a vertical cross-section relative to the longitudinal direction. The adjustment actuator 4020 is inserted into the recess 4026 formed between the protrusions, which contacts the front ends of the hemispherical fourth protrusion 4021a and the fifth protrusion 4021b and the semi-cylindrical sixth protrusion 4023a and the seventh protrusion 4023, and is guided along the outer circumference of the hemispherical surface and the semi-cylindrical surface in the recess 4026.

[0225] To Figure 23The lamp chamber S shown in the figure has multiple bottomed cylindrical protrusions 4021a, 4021b, 4023a, and 4023b, which are integrally formed with the lamp body 4002 and project from a portion of the back wall 4006 of the lamp body 4002. This configuration reduces weight and improves the rigidity of the lamp body 4002 against bending stress. Furthermore, the fourth and fifth protrusions 4021a and 4021b are formed to contact both sides of the adjustment actuator 4020, a lamp component, thereby positioning the adjustment actuator 4020 relative to the adjustment screw 4025. The fourth and fifth protrusions 4021a and 4021b are higher than the sixth and seventh protrusions 4023a and 4023b, making it easier to insert the front end of the adjustment actuator 4020. The sixth and seventh protrusions 4023 a and 4023 b have an elongated shape toward the adjustment screw 4025 , thereby making it easy to guide the adjustment actuator 4020 toward the adjustment screw 4025 .

[0226] The plurality of protrusions 4021a, 4021b, 4023a, and 4023b ensures necessary and sufficient rigidity in the lamp body 4002 even without providing ribs, thereby reducing the weight of the lamp body 4002 and the vehicle lamp 4001. Furthermore, the protrusions 4021a, 4021b, 4023a, and 4023b allow a guide for the adjustment actuator 4020 toward the adjustment screw 4025 to be formed on the lamp body 4002 with a simple structure.

[0227] Furthermore, in this embodiment, in order to more easily guide the adjustment actuator 4020 to the adjustment screw 4025, the sixth and seventh protrusions 4023a and 4023b of a long strip shape are provided between the fourth and fifth protrusions 4021a and 4021b and the adjustment screw 4025. However, instead of the sixth and seventh protrusions 4023a and 4023b, one or more members corresponding to the fourth and fifth protrusions 4021a and 4021b may be provided. Specifically, Figure 24 As shown by the two-dot chain line portions indicated by reference numerals 4022a and 4022b in the figure, a pair of protrusions corresponding to the fourth and fifth protrusions 4021a and 4021b may be further provided between the adjusting screw 4025. By arranging a plurality of pairs of protrusions corresponding to the fourth and fifth protrusions 4021a and 4021b toward the adjusting screw 4025, the adjusting actuator 4020 can be easily guided by the adjusting screw 4025, similar to the case where it is guided by the sixth and seventh protrusions 4023a and 4023b.

[0228] (Vehicle lighting)

[0229] Next, use Figures 30 to 38B Embodiments of the present disclosure will be described.

[0230] Figure 30 FIG. 5 is a schematic front view of a vehicle lamp 5001 according to a preferred embodiment of the present disclosure. The vehicle lamp 5001 is a headlamp installed at the left and right corners of the front of the vehicle. Figure 30 As shown, a vehicle lamp 5001 includes a container-shaped lamp body 5002 having a front opening 5002′, and a front cover 5004 assembled to the front opening 5002′ of the lamp body 5002. The front cover 5004 is made of, for example, a light-transmitting resin such as polycarbonate or glass. By attaching the front cover 5004 to the front opening 5002′ of the lamp body 5002, a lamp chamber S is defined on the inside.

[0231] The divided lamp chamber S houses a high-beam lamp unit Hi and a low-beam lamp unit Lo. These are optical units configured to direct light emitted from a light source toward the front of the vehicle, creating high-beam and low-beam light distributions. Each lamp unit (Hi, Lo) can utilize conventionally known structures, such as reflector-type or projector-type lamp units, and their types are not limited.

[0232] (Overall shape of the lamp body)

[0233] The shape of the lamp body 5002 will be described in detail. Figure 31 This is a schematic front view of the lamp body 5002.

[0234] The lamp body 5002 is formed by injection molding using a hard synthetic resin material. Sealing grooves 5003 are provided around the periphery of the front opening 5002′ of the lamp body 5002, which engage with sealing legs provided on the periphery of the front cover 5004. Vehicle mounting portions 5005 for attaching the vehicle lamp 5001 to the vehicle body are protruding from the outer surface of the periphery of the front opening 5002′ of the lamp body 5002, corresponding to the shape of the mounting portion on the vehicle body. The vehicle mounting portions 5005 are provided at three locations on the upper side and two locations on the left side, for a total of five locations on the outer surface of the lamp body 5002.

[0235] The lamp body 5002 comprises a back wall 5006, a top surface 5007, a bottom surface 5008, and left and right side surfaces 5009. The back wall 5006 bulges rearward and is connected to the adjacent top surface 5007, bottom surface 5008, and side surfaces 5009 in a curved, continuous manner via ridgelines. Furthermore, the top surface 5007, bottom surface 5008, and side surfaces 5009 are generally convexly curved, gently bulging toward the outside of the lamp body 5002. They curve gently at their edges, connecting continuously without bends or steps. Consequently, the lamp body 5002 is formed as a whole in the shape of a container with rounded corners.

[0236] The bottom surface 5008 extends forward from the lower edge of the rear wall 5006 and is connected to the sealing groove 5003 provided at the edge of the front opening 5002' of the lamp body 5002. The side surfaces 5009 extend laterally and slightly forward from the left and right edges of the rear wall 5006 and are connected to the sealing groove 5003. The top surface 5007 extends slightly, gently curving rearward and downward from the edge of the sealing groove 5003 and extending to connect to the rear wall 5006, forming a substantially integral body with the rear wall 5006.

[0237] Therefore, the back wall 5006, top surface 5007, bottom surface 5008 and side surfaces 5009, 5009 are mainly not planes, but are composed of curved surfaces with a large curvature radius, and the lamp body 5002 is formed as a whole into a container shape with the back wall 5006 as the bottom, and the back wall 5006, top surface 5007, bottom surface 5008 and side surfaces 5009 respectively form container surfaces whose curved surfaces are smoothly continuous with each other.

[0238] The lamp body 5002 is formed with a first unit mounting hole 5031, a second unit mounting hole 5032, and a third unit mounting hole 5033. The first unit mounting hole 5031 is for mounting the low-beam lamp unit Lo and is formed in the upper left corner of the rear wall 5006. The second unit mounting hole 5032 is for mounting the rear cover (not shown) and is formed in the upper right corner of the rear wall 5006. The third unit mounting hole 5033 is for mounting a lamp driver module (not shown) that controls the lighting of the lamp units (Hi and Lo) and is formed approximately in the center of the lower portion of the rear wall 5006.

[0239] Furthermore, a first calibration member mounting hole 5041, a second calibration member mounting hole 5042, and a third calibration member mounting hole 5043 are formed in the lamp body 5002 around the third unit mounting hole 5033. A calibration member (not shown) of a conventionally known structure is mounted in each of these calibration member mounting holes 5041, 5042, and 5043.

[0240] The first calibration component mounting hole 5041 is provided at the lower edge of the back wall 5006 so as to be positioned between the first unit mounting hole 5031 and the third unit mounting hole 5033. The second calibration component mounting hole 5042 is provided at the lower right edge of the back wall 5006 so as to be offset in the opposite direction from the first calibration component mounting hole 5041 by a distance substantially equal to the distance from the third unit mounting hole 5033 to the first calibration component mounting hole 5041. The third calibration component mounting hole 5043 is provided at the upper right end of the back wall 5006 so as to be positioned substantially vertically above the second calibration component mounting hole 5042.

[0241] (Back wall and beam)

[0242] On the back wall 5006, first beams 5061, second beams 5062, third beams 5063, and fourth beams 5064, which constitute a portion of the back wall 5006, extend from the upper end to the lower end of the back wall 5006. Here, the portion of the back wall 5006 other than the components of beams 5061 to 5064 is referred to as a back wall body 5069.

[0243] The first beam 5061 extends upward and rightward from the first alignment member mounting hole 5041 at the lower left of the back wall 5006 to the upper end of the back wall 5006. Therefore, the first beam 5061 is formed to be inclined rightward in a front view.

[0244] The second beam 5062 extends from the second alignment member mounting hole 5042 at the lower right portion of the back wall 5006 toward the upper left to the upper end portion of the back wall 5006. Therefore, the second beam 5062 is formed to be inclined to the left in a front view.

[0245] The third beam 5063 extends to connect the second calibration member mounting hole 5042 at the lower right corner of the back wall 5006 and the third calibration member mounting hole 5043 at the upper corner. Therefore, the third beam 5063 extends straight upward to the upper end of the back wall 5006 when viewed from the front.

[0246] The fourth beam 5064 extends to connect the second alignment member mounting hole 5042 at the lower right side of the back wall 5006 and the second unit mounting hole 5032 at the upper side.

[0247] Figures 32A to 32D It is along Figure 31 The cut lines are end views of the beams 5061 to 5064 shown. Figure 32A It is along Figure 31 The end view along line AA mainly shows the cross-sectional shape of the first beam 5061 . Figure 32B It is along Figure 31 The end view along line BB mainly shows the cross-sectional shape of the second beam 5062 . Figure 32C It is along Figure 31 The end view of the CC line mainly shows the cross-sectional shape of the third beam 5063. Figure 32D It is along Figure 31 The end view along the DD line mainly shows the cross-sectional shape of the fourth beam 5064.

[0248] like Figures 32A to 32DAs shown, the cross-sectional shapes of the beams 5061-5064 perpendicular to their extension directions vary in curvature radius, width, and protrusion, but are all generally arcuate. The curved surfaces of the beams 5061-5064 can protrude in either the direction toward the lamp chamber S (forward) or outward (rearward). In this embodiment, the beams 5061-5064 are curved toward the lamp chamber S (forward). This cross-sectional shape of the lamp body 5002 maintains a constant wall thickness, lacks curved portions, and is continuous.

[0249] Figure 33 FIG. 5 is a front view of the lamp body 5002, in which the beams 5061 to 5064 are represented in gray. Figure 33 As shown, each beam 5061-5064 extends from the upper end to the lower end of the back wall 5006, with other beams extending obliquely from the ends of certain beams, forming a truss structure with triangular units. The thick-walled sealing groove 5003 is incorporated into the truss structure. Consequently, the lamp body 5002, including the back wall 5006, is resistant to deformation under load. Furthermore, since the beams 5061-5064 themselves are curved surfaces with a roughly arc-shaped cross-section that disperses stress, the structure is highly rigid and more resistant to deformation.

[0250] Therefore, the lamp body 5002 of this embodiment has a higher rigidity than lamp bodies without such a truss structure. Due to the improved rigidity of the lamp body 5002, the lamp body 5002 is thinner than conventional lamp bodies and has the same rigidity as conventional lamp bodies.

[0251] (Snap-fit structure)

[0252] The engaged member 5099 disposed in the lamp chamber S is directly engaged with the lamp body 5002 by an engaging structure provided in the lamp body 5002. The engaging structure provided in the lamp body 5002 will be described in detail.

[0253] Figures 34A to 37B yes Figure 31 The H portion shown. The engaged component 5099 is engaged with the H portion of the lamp body 5002. Figure 34A 、 Figure 34B yes Figure 31 The front view of the H section is shown. Figure 34A Only the lamp body 5002 is shown, indicating a state where the engaged component 5099 is not engaged (before engagement). Figure 35A It is a front perspective view of the lamp body 5002 of the H portion. Figure 35B This is a perspective view of the back of the lamp body 5002 in the H portion. Figure 36 This is an exploded perspective view of the H section. Figure 37A It is along Figure 34AEnd view of the HH line shown. Figure 37B It is along Figure 34A End view of the JJ line shown.

[0254] The engaged component 5099 engaged with the lamp body 5002 is a dehumidifying unit that has the function of discharging moisture in the lamp chamber S to the outside of the lamp chamber S. The engaged component 5099 is not limited to this, and any component such as a leveling actuator or a driving circuit disposed in the lamp chamber S may be used, and its shape and size are not limited.

[0255] like Figure 36 As shown, the engaged member 5099 is composed of an engaged member body 5090 and a cover 5080. The engaged member body 5090 has a substantially rectangular parallelepiped shape, and is formed with three protrusions as the cover engaged portion 5096, two on the upper surface and one on the bottom surface.

[0256] The cover 5080 is a flat plate that covers the back surface of the engaged component body 5090 like a lid and is fixed to the engaged component body 5090. Cover engaging portions 5086 corresponding to the cover engaged portions 5096 are provided at the upper edge and lower end of the cover 5080. The cover engaging portions 5086 engage with the cover engaged portions 5096, thereby integrating the engaged component body 5090 and the cover 5080 to form the engaged component 5099. The engagement between the cover 5080 and the engaged component body 5090 can employ conventional engagement structures such as a concave-convex engagement or a spear engagement, and is not particularly limited. Alternatively, the cover 5080 can be fastened to the engaged component body 5090 using fixing members such as screws.

[0257] Flat female engagement parts 5081 to 5083 that protrude horizontally toward the front are further formed at the upper edge and lower end of the cover 5080. Engagement holes 5081a to 5083a are formed in the center of the female engagement parts 5081 to 5083.

[0258] The first female engagement portion 5081 is provided at the center of the upper edge of the cover 5080 between the two cover engagement portions 5086. The second female engagement portion 5082 and the third female engagement portion 5083 are provided at the lower edge of the cover 5080 with the cover engagement portion 5086 interposed therebetween. The female engagement portions 5081 to 5083 are arranged alternately with the three cover engagement portions 5086.

[0259] When the cover 5080 is engaged and integrated with the engaged component body 5090, the female engaging portions 5081 to 5083 provided on the cover 5080 are arranged on the upper and lower surfaces of the engaged component 5099. Alternatively, the cover 5080 may be omitted and the female engaging portions 5081 to 5083 may be provided directly on the upper and lower surfaces of the engaged component body 5090.

[0260] The following describes the engaging structure provided in the lamp body 5002. A vertical plane portion 5074 is formed in a portion of the rear wall 5006, which is mainly composed of a curved surface, and which abuts against the engaging member 5099 when engaged.

[0261] The vertical plane portion 5074 is formed in a substantially rectangular shape corresponding to the contact surface (back surface) of the substantially rectangular parallelepiped engaged member 5099. The vertical plane portion 5074 has side edges of an upper side 5074a, a lower side 5074b, a left side 5074c, and a right side 5074d.

[0262] The back wall 5006 curves toward the back side (rear) from the left side 5074c and the right side 5074d of the vertical plane portion 5074, and curves forward at a substantially right angle from the lower side 5074b of the vertical plane portion 5074. Therefore, a horizontal portion 5078 is formed continuously from the lower end of the vertical plane portion 5074. The back wall 5006 curves further downward at the front end of the horizontal portion 5078, and the horizontal portion 5078 constitutes the horizontal surface of the back wall 5006 formed in a stepped shape.

[0263] When the engaged member 5099 is engaged, a portion of the engaged member 5099 is placed on the horizontal portion 5078 .

[0264] A second male engagement portion 5072 and a third male engagement portion 5073 are formed on the surface of the horizontal portion 5078 as protrusions (lances) that protrude upward.

[0265] Furthermore, a first male engagement portion 5071 is formed to protrude forward from the upper side 5074a. A lance 5071a is formed on the surface of a bottom portion 5071c of the first male engagement portion 5071 that contacts the engaged member 5099 and protrudes downward.

[0266] The first male engaging portion 5071, the second male engaging portion 5072, and the third male engaging portion 5073 are formed to correspond to the first female engaging portion 5081, the second female engaging portion 5082, and the third female engaging portion 5083, respectively. The back surface of the engaged component 5099 is arranged to abut against the vertical plane portion 5074, and the female engaging portions 5081-5083 engage with the male engaging portions 5071-5073, respectively. This allows the engaged component 5099 to be directly fixed to the back wall 5006 of the lamp body 5002 without requiring fixing members such as bolts or screws.

[0267] The engagement between the female engagement parts 5081 to 5083 and the male engagement parts 5071 to 5073 is a so-called spear-type engagement.

[0268] The spear-type engagement mechanism creates a temporary engagement resistance in either the female or male engagement portion during the engagement process. When the tool overcomes this resistance and passes through, the easing of the engagement resistance provides a sense of rhythm (a click) to the operator. Furthermore, the momentum of the passage engages the two engagement portions. A portion of the male engagement portion's passageway is formed into a barbed hook (a spear). Once the male and female engagement portions engage, the spear hooks onto the female engagement portion, preventing disengagement and maintaining the engagement.

[0269] The first male engagement portion 5071 is hollow and is formed by a portion of the back wall 5006. Figure 37A As shown, a first male engaging portion 5071 is formed on the rear wall 5006 protruding forward. This is because the rear wall 5006, which is continuous from the upper side 5074a of the vertical plane portion 5074, is temporarily bent forward, then bent upward, and then bent back backward to form the first male engaging portion 5071. Therefore, the first male engaging portion 5071 constitutes a part of the rear wall 5006 and is hollow.

[0270] Similarly, the horizontal portion 5078 formed by bending the lower side 5074b of the vertical plane portion 5074 also constitutes a portion of the back wall 5006. In other words, the vertical plane portion 5074, the horizontal portion 5078, and the first male engaging portion 5071 all constitute a portion of the back wall 5006 and are continuous. The engaged component 5099 is inserted and accommodated in the space S2 formed by the vertical plane portion 5074, the horizontal portion 5078, and the first male engaging portion 5071.

[0271] (Effect)

[0272] use Figure 38A 、 Figure 38B The effects of this structure will be described. Figure 38A 、 Figure 38B It is along Figure 34A The end view along the JJ line shows the process of engagement between the engaged component 5099 and the lamp body 5002 .

[0273] As described above, the engagement between the female engagement parts 5081 to 5083 and the male engagement parts 5071 to 5073 is a spear-shaped engagement, and one or both of the female engagement parts 5081 to 5083 and the male engagement parts 5071 to 5073 are elastically deformed relative to the engagement resistance, so that the spear-shaped parts overcome the engagement resistance and pass through to achieve the engagement state.

[0274] When the engaged member 5099 is engaged with the back wall 5006, the second female engaging portion 5082 and the third female engaging portion 5083 provided on the bottom surface of the engaged member 5099 are first hooked into the second engaging hole 5072a and the third engaging hole 5073a in a manner of being inserted from above obliquely, and are engaged with the second male engaging portion 5072 and the third male engaging portion 5073 of the horizontal portion 5078 (see FIG. Figure 38A ). Then, the engaged part 5099 is rotated with the two engaged points as fulcrums, and the engaged part 5099 is pressed toward the vertical plane portion 5074 located at the back. The first male engaging portion 5071 is pushed up by the engaged part 5099 that is moving backward, and is elastically deformed in a manner of opening upward (refer to Figure 38A As a result, the space S2 expands, and the lance 5071a protruding toward the space S2 passes over the first female engagement portion 5081 and fits into the first engagement hole 5081a, thereby becoming engaged (see FIG. Figure 38B The elastic deformation of the first male engaging portion 5071 returns to its original state without load, and the engaged component 5099 is fixed to the back wall 5006 to prevent it from coming off.

[0275] In this way, by elastically deforming at least a portion of the lamp body 5002 constituting the engaging portion, or the lamp body 5002 near the engaging portion, the engaged component 5099 engages with the lamp body 5002. Fixing components such as bolts or screws are unnecessary, and the engaged component 5099 can be directly and easily engaged with the engaging portion provided on the lamp body 5002.

[0276] The elastic deformation of the lamp body 5002 for engagement can be achieved by changing the shape of the lamp body 5002 or by thinning the wall of the lamp body 5002. By thinning the wall of the portion to be engaged, the lamp body 5002 is more easily elastically deformed, and the engaged component 5099 can be directly engaged with the lamp body 5002 using the engaging portion provided on the lamp body 5002.

[0277] If the engaging portion is formed as a hollow protrusion formed from the lamp body 5002, as in the case of the first male engaging portion 5071, the engaging portion itself preferably constitutes the lamp body 5002 and is easily elastically deformable. A protruding, hollow first male engaging portion 5071 is not essential. For example, similar to the horizontal portion 5078, the first male engaging portion 5071 may also be formed in a stepped shape. In this case, the space S2 is formed as a recessed portion extending from the rear wall 5006 toward the rear surface, with a lance formed on the surface forming the recess.

[0278] The lamp body 5002 of this embodiment is primarily composed of curved surfaces, which improves rigidity while maintaining the same level of rigidity as conventional lamps. Furthermore, it is thinner than conventional lamps, allowing for easier elastic deformation and greater resistance to deformation loads. During engagement, the entire lamp body 5002 elastically deforms centered around the engaging portion, distributing the load across the entire body. Even if deformation occurs, the lamp body is less susceptible to damage. This design is suitable for a fully engaged structure in which at least a portion of the lamp body 5002 elastically deforms to achieve the engaged state.

[0279] The entire lamp body 5002 does not need to be elastically deformed, and can be a structure in which only a portion of the area required for engagement is elastically deformed. If the area of the lamp body 5002 elastically deforms during engagement is large, the load generated by the elastic deformation is distributed accordingly, suppressing the breakage of the engagement portion caused by the engagement load, which is therefore preferred.

[0280] Alternatively, the engaging portion including the first male engaging portion 5071 may be deformed in a wide range of the entire engaging portion to engage the engaged component 5099. Figures 39A to 39C The engagement process in this case will be described.

[0281] Figures 39A to 39C It is along Figure 34A The end view along the JJ line shows another process of engagement between the engaged component 5099 and the lamp body 5002 .

[0282] First, the engaged member 5099 is arranged in the space S2 sandwiched between the horizontal portion 5078 and the first male engagement portion 5071 (see Figure 39A ). Next, the engaged member 5099 is pressed into the space S2 and moved in the rear direction (refer to Figure 39B ). The first male engaging portion 5071 provided with a lance 5071a and the horizontal portion 5078 provided with a second male engaging portion 5072 and a third male engaging portion 5073 are opened up and down in such a manner as to expand the space S2 (refer to Figure 39B As the back wall 5006 deforms, the space S2 expands, and the lance 5071a, the second male engaging portion 5072, and the third male engaging portion 5073 protruding toward the space S2 pass over the female engaging portions 5081 to 5083 and fit into the engaging holes 5081a to 5083a, thereby forming an engaged state (see FIG. Figure 39C After elastic deformation, the first male engaging portion 5071 and the horizontal portion 5078 return to their original unloaded and deformed state, and the lance 5071a, the second male engaging portion 5072, and the third male engaging portion 5073 provided on the first male engaging portion 5071 and the horizontal portion 5078 prevent the engaged component 5099 from falling off.

[0283] During this engagement process, the horizontal portion 5078, which includes the second male engagement portion 5072 and the third male engagement portion 5073, elastically deforms and engages with the second female engagement portion 5082 and the third female engagement portion 5083. Therefore, the horizontal portion 5078 is also included in a portion of the engagement portion. The vertical plane portion 5074 also warps and elastically deforms to achieve engagement, and the entire lamp body 5002 surrounding the area provided with the space S2 deforms to achieve engagement.

[0284] like Figure 36 As shown, the engaged component 5099 is a dehumidification unit, and therefore a cover opening 5085 serving as a dehumidification port is provided in the cover 5080. A lamp body opening 5075 is also provided in the vertical plane portion 5074 of the lamp body 5002 corresponding to the cover opening 5085, and a filter FI is provided to cover the lamp body opening 5075 (see FIG. Figure 35B and Figure 37A ).like Figure 37A As shown, when the engaging member 5099 is engaged, the two openings are connected.

[0285] The engaged component 5099 is not limited to the dehumidifying unit, so the two openings are not required. However, by directly securing the dehumidifying unit to the lamp body 5002, there is no need for an air duct from the dehumidifying port of the dehumidifying unit to the dehumidifying port of the lamp body, thereby achieving a smaller and lighter vehicle lamp 5001. Similarly, if the engaged component 5099 is arranged so that components removed from the engaged component 5099 through the opening of the lamp body 5002 to the outside of the lamp chamber S, such as connector ports and cables, are exposed from the opening of the lamp body 5002 when engaged, this saves space in the lamp chamber S, thereby achieving a smaller and lighter vehicle lamp 5001, which is more ideal.

[0286] like Figure 38A 、 Figure 38B As shown, protrusions 5076 are provided on the surface of the vertical plane portion 5074. The protrusions 5076 protrude toward the space S2, forming abutment against the configured engaged component 5099. Specifically, the protruding protrusions 5076 press against the back surface of the engaged engaged component 5099, resisting the force of this pressure to secure the engagement. While protrusions 5076 are provided at three locations on the vertical plane portion 5074, the number and placement of protrusions are not limited to this. To achieve this effect, protrusions may also be provided on the abutment surface (back surface) of the engaged component 5099.

[0287] Likewise, if Figure 34A 、 Figure 34BAs shown, a first protrusion 5071b that bulges toward space S2 is provided on the bottom portion 5071c of the first male engaging portion 5071. A second protrusion 5078a that bulges toward space S2 is also provided in the center of the horizontal portion 5078.
