Description

[Technical field]

[0001] The present invention relates to a vehicle lamp, and more particularly to a bracket for a vehicle lamp. [Background technology]

[0002] Conventionally, brackets for fixing lamp units have been used that have a planar structure based on a surface facing the front direction as a whole. For example, the bracket shown in Patent Document 1 has a planar structure facing the front direction on the rear side, and a recess for fixing the lamp unit is provided within the planar structure. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-160603 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the bracket of Patent Document 1, the aiming screw mounting holes and component fastening holes for fixing components such as the lamp unit are formed within the planar structure, which increases the front dimension of the bracket and results in an increase in weight.

[0005] In addition, brackets with a surface structure facing the front direction have low rigidity against bending stress in the front-rear direction. For this reason, although omitted in Patent Document 1, it is technically common knowledge to provide reinforcing members such as ribs around the aiming screw mounting holes and component fastening holes, which results in an increase in weight. For this reason, there has been a growing demand for a new lightweight bracket shape.

[0006] The present invention has been made in consideration of the above circumstances, and has an object to provide a lightweight bracket having a new shape. [Means for solving the problem]

[0007] In order to achieve the above object, a bracket for a vehicle lamp according to one aspect of the present invention has the following configuration. 1. A wall that extends in a front-to-rear direction to form a cylindrical structure that opens in the front-to-rear direction, and defines a storage space for storing and fixing at least a portion of at least one lamp unit that irradiates light forward, and at least one through hole forming portion that has a through hole formed in the center and has an external shape roughly similar to that of the through hole, and is provided on the wall so as to protrude from the wall in a direction intersecting the front-to-rear direction, and the wall extends in the front-to-rear direction so as to follow at least a portion of the outer circumferential edge of the through hole forming portion.

[0008] 2. In the above aspect 1, the wall may be an outer circumferential wall that defines the storage space.

[0009] 3. In the above aspects 1 and 2, the storage space may be partitioned into two or more spaces that open in the front-rear direction, and at least one intermediate wall extending in the front-rear direction may be provided.

[0010] 4. In the above aspects 1 to 3, at least a portion of the wall may be configured as a double wall, and the through-hole forming portion may be provided on a wall surface of the portion of the wall configured as the double wall.

[0011] In a bracket having a basic cylindrical structure extending in the front-rear direction, the rigidity of the entire bracket is improved by making at least a part of the intermediate wall and / or the outer peripheral wall a double wall. On the other hand, the weight increases when the bracket is double-walled, but since there is no front or rear wall and a space is formed between the double walls, the increase in weight is limited. Furthermore, by making the bracket double-walled, even if one wall is shaped to fit the through-hole forming portion, it is possible to make it different from the other wall in the same shape, thereby improving the freedom of material projection.

[0012] 5. In the above aspects 1 to 4, the wall surface of the wall may be a free curved surface extending by extruding a free curve in the front-rear direction.

[0013] 6. In the above embodiments 1 to 5, the device may further include at least one partition wall that divides the inter-wall space extending in the front-to-rear direction defined between the double walls into a plurality of small spaces extending in the front-to-rear direction, and at least one of the partition walls may be arranged to cross between the double walls.

[0014] 7. In the above embodiments 1 to 6, the through hole forming portion may be arranged so that the outer peripheral edge portion contacts a wall that defines two or more small spaces defined by the partition wall arranged to cross between the double walls.

[0015] 8. In the above embodiments 1 to 7, at least one of the small spaces separated by the partition wall may be provided with an internal wall that blocks the front-to-rear direction of the small space, and at least a pair of adjacent small spaces may each be provided with the internal walls, which are arranged alternately in the front-to-rear direction.

[0016] With the above-mentioned configuration, the internal walls become a bridge structure that supports the partition walls, improving the rigidity against deflection in the front-to-rear direction. In particular, the alternating front-to-rear direction makes it even less likely to deflect. Furthermore, the presence or absence of an internal wall and the size of the internal wall can be set for each small space, so it is possible to ensure both rigidity and weight reduction without excessive weight increase. Effect of the Invention

[0017] In the above aspect, a lightweight bracket having a new shape can be provided. [Brief description of the drawings]

[0019] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative and do not limit the invention, and all of the features and combinations thereof described in the embodiments are not necessarily essential to the invention.

[0020] (Vehicle lighting fixtures) FIG. 1 is a schematic front view of a vehicle lamp 1 including a bracket 6 according to an embodiment. The vehicle lamp 1 is a headlamp, and is attached to both the left and right sides of the front of the vehicle. The vehicle lamp 1 includes a lamp body 2 and a front cover 4 as a lamp housing. The lamp body 2 has a container shape with an opening at the front, and the front cover 4 is attached to the opening to form a lamp chamber S inside. The front cover 4 is a so-called outer cover, and is a substantially transparent lens made of a translucent resin such as polycarbonate. The front cover 4 may be formed with an optical step for dispersing and diffusing the light emitted from the light source when the lamp is turned on.

[0021] Within the defined lamp chamber S, three lamp units LU1 to LU3 supported by a bracket 6 are housed side by side in the vehicle width direction (left and right direction). The lamp units LU1 to LU3 are a single lamp unit or multiple lamp units that radiate light forward, and each is an optical unit configured to form a predetermined light distribution such as a high beam distribution or a low beam distribution. The light radiated from the lamp units LU1 to LU3 is radiated toward a front cover 4 disposed in front, passes through the front cover 4, and forms a predetermined light distribution in front of the vehicle. The lamp units LU1 to LU3 are of a conventionally known configuration, for example, a reflective type, a projector type, or the like, and the type is not important.

[0022] Fig. 6 is a front view of the bracket 6 showing a state in which the lamp units are supported. As shown in Fig. 6, the lamp units LU1 to LU3 are provided with support frames LU12, 22, and 32 on the front cover side, and the support frames LU12, LU22, and LU32 support projection lenses LU11, 21, and 31, respectively. The lamp units LU1 to LU3 are also provided with reflectors (not shown) that cover the light sources in a semi-dome shape and metallic heat sinks LU14, LU24, and LU34, and are fixed to boss formation portions 71 to 74 as fixing portions of the bracket 6 and mounting members 81 to 84 by fixing members F11, F21 to F24, F31 to F34, such as bolts, aiming screws, and mounts.

[0023] The bracket 6 is attached to the rear surface of the lamp body 2 by three aiming screws E1 to E3. The optical axes of the lamp units LU1 to LU3 are adjusted in the horizontal and vertical directions by rotating the aiming screws E1, E3.

[0024] The bracket 6 according to the present embodiment can be used not only for headlights but also for vehicle lamps such as rear combination lamps and signs. In the vehicle lamp 1, the direction in which the light of the lamp units LU1 to LU3 is irradiated, where the front cover 4 is arranged, is defined as the forward direction, and the rear, left and right directions, and up and down directions are determined based on this. When the vehicle lamp 1 is, for example, a rear lamp and is arranged on the rear surface of the vehicle, the vehicle lamp 1 is rotated 180° and mounted on the vehicle, and it goes without saying that the front of the vehicle lamp 1 is the rear of the vehicle. In addition, in the bracket 6, the extension direction of the bracket 6 described later is defined as the front-rear direction, and will be described as coinciding with the front-rear direction of the vehicle lamp.

[0025] (bracket) The shape of the bracket 6 will be described in detail below with reference to Figs. 2 to 5. Fig. 2 is a front view of the bracket 6. Fig. 3 is a rear view of the bracket 6. Fig. 4 is a front perspective view of the bracket 6. Fig. 5 is a rear perspective view of the bracket 6. In Figs. 2 to 5, the bracket 6 is colored in light ink.

[0026] The bracket 6 is formed by injection molding using a hard synthetic resin material. The bracket 6 has a cylindrical structure that extends in the front-rear direction and opens in the front-rear direction. The bracket 6 is mainly composed of an upper wall 100, a right wall 200, a lower wall 300, and a left wall 400. Hereinafter, the upper wall 100, the right wall 200, the lower wall 300, and the left wall 400 that form the outer shape of the bracket 6 will be collectively referred to as the outer peripheral wall 10.

[0027] As shown in Figs. 2 and 3, the outer peripheral wall 10 is mainly composed of a wall having a generally constant thickness and extending in one direction (front-rear direction). Most of the outer and inner surfaces of the outer peripheral wall 10 are free-form surfaces that are curved or have a non-constant radius of curvature. The bracket 6 has a cylindrical structure without a front wall and a back wall, and is therefore lighter than a housing having a front wall and a back wall and having necessary standing walls. It also has higher rigidity than a flat or arch-shaped bracket. In addition, since it does not have a front wall and a back wall and is mainly composed of walls extending in the front-rear direction, it is suitable for injection molding using a mold with the mold removal direction set to the extension direction (front-rear direction) of the outer peripheral wall 10 of the bracket 6. The molding process will be described in detail later.

[0028] The outer peripheral wall 10 extends in the front-rear direction, and only the end face of the outer peripheral wall 10 is visible when viewed from the front (see Figs. 2 and 3). Although the outer peripheral wall 10 extends in the same direction (front-rear direction), each wall is not an extruded shape in which a predetermined cross-sectional shape is extruded by a predetermined length, and the depth length (length in the front-rear direction) is different for each wall. Therefore, the cross-sectional shape perpendicular to the depth direction is not the same shape at any position. Furthermore, each wall does not extend with a uniform length. For example, as shown in Fig. 4, the left wall 400 has a shorter depth length than the right wall 200. Furthermore, the left wall 400 has a shorter depth length (length in the front-rear direction) in the upper region, and the depth length in the lower region is longer than the depth length in the upper region.

[0029] An accommodation space SP in which at least a part of the lamp units LU1 to LU3 are accommodated is formed inside the compartment defined by the cylindrical outer wall 10. In this embodiment, the bracket 6 is relatively short in the depth direction (front-rear direction) and longer in the width direction (left-right direction) than in the height direction (up-down direction), so that the accommodation space SP as a whole inside the outer wall 10 has a substantially rectangular parallelepiped shape that is long in the width direction. Therefore, the lamp units LU1 to LU3 are accommodated in the accommodation space SP, particularly on the upper surface side, in a state where they protrude outward from the accommodation space SP.

[0030] The storage space SP is divided into three spaces (storage spaces SP1 to SP3) in the left-right direction by a right intermediate wall 600 and a left intermediate wall 500 (hereinafter, simply referred to as intermediate walls when referring to both) that are provided in the storage space SP and extend in the up-down direction. Therefore, the storage space SP refers to the entire storage spaces SP1 to SP3. The right intermediate wall 600 and the left intermediate wall 500 extend in the same direction (front-back direction) as the outer peripheral wall 10. The lamp units LU1 to LU3 are disposed in each of the three storage spaces SP1 to SP3 that are arranged in the left-right direction and are partitioned by the outer peripheral wall 10, the right intermediate wall 600, and the left intermediate wall 500 (see FIG. 6). Note that the walls in the claims include the outer peripheral wall 10, i.e., the upper wall 100, the right wall 200, the lower wall 300, and the left wall 400, and the intermediate walls, i.e., the right intermediate wall 600 and the left intermediate wall 500.

[0031] The right wall 200, the left wall 400, the right intermediate wall 600, and the left intermediate wall 500 are provided with boss forming portions 71-74 and plate-shaped mounting members 81-84 as through-hole forming portions, which protrude toward the three storage spaces SP1-SP3 in a direction intersecting the front-rear direction of the lamp. The boss forming portions 71-74 and the mounting members 81-84 are provided with through-holes 71a-74a and 81a-84a, respectively, which penetrate in the front-rear direction, which is the extension direction of the bracket 6. As shown in FIG. 6, the lamp units LU1-LU3 are accommodated in the predetermined storage spaces SP1-SP3, respectively, and are attached to and supported by the bracket 6 by being fixed to the corresponding boss forming portions 71-74 and mounting members 81-84 by fixing members such as screws and bolts. The boss forming portions 71, 72, and 74 correspond to the through-hole forming portions in the claims, which will be described later.

[0032] In this embodiment, the storage space SP is divided into three to support the lamp units LU1 to LU3. However, there is no limit to the number and arrangement of the lamp units, and the storage space SP may be defined only by the outer peripheral wall 10 without providing an intermediate wall, and one lamp unit may be supported. Alternatively, an intermediate wall extending in the vertical direction and an intermediate wall extending in the horizontal direction perpendicular to the intermediate wall may be provided to form an intermediate wall having a cross-shaped vertical section, and the cross-shaped intermediate wall and the outer peripheral wall 10 may define four storage spaces to fix the four lamp units. In this case, the boss forming portions 71 to 74 and the mounting members 81 to 84 may be provided on the outer peripheral wall 10.

[0033] Aiming support portions 91-93 are formed at three corners, the lower left corner, the lower right corner, and the upper right corner, of the bracket 6. The aiming support portions 91-93 are rectangular flat plate-like and are provided so as to define three corners of a general rectangle in a front view that constitutes the outer circumferential wall 10. The aiming support portions 91-93 will be described later.

[0034] (double wall) The structure of the walls constituting the bracket 6 will be described with reference to the drawings. In addition to Figs. 2-5, Fig. 7 is a diagram for explaining the structure of the walls constituting the bracket 6. Fig. 8 is a front view of the bracket 6 showing the cutting line of the cross-sectional view of the bracket 6 in Figs. 9-10. In Fig. 8, the bracket 6 is also shown colored with light ink. Figs. 9 and 10 are cross-sectional views of the bracket 6. Fig. 9(A) is a cross-sectional view taken along line AA in Fig. 8. It mainly shows the double wall portion of the right wall 200 (part AA in Fig. 7). Fig. 9(B) is a cross-sectional view taken along line BB in Fig. 8. It mainly shows the double wall portion of the lower wall 300 (part BB in Fig. 7). Fig. 10(A) is a cross-sectional view taken along line CC in Fig. 8. It mainly shows the double wall portion of the left intermediate wall 500 (part CC in Fig. 7). Fig. 10(B) is a cross-sectional view taken along line DD in Fig. 8. It mainly shows the double wall portion of the upper wall 100 (part DD in Fig. 7). FIG. 8 also shows the cutting lines of the cross-sectional view of the bracket in FIG. 11, but this will be described later.

[0035] The bracket 6 is configured such that the upper wall 100, the right wall 200, the lower wall 300, and the left wall 400, i.e., the outer peripheral wall 10, and the right intermediate wall 600 and the left intermediate wall 500, i.e., at least a part of the intermediate wall 60, are double walls. The outer peripheral wall 10 and the intermediate wall do not necessarily both have to be double walls. Only the outer peripheral wall 10 may include a double wall, or only the intermediate wall may include a double wall. The lightly shaded parts shown in FIG. 7 are the main double wall parts of the bracket 6. Also, in FIG. 7, the reference numerals of each part are omitted because the purpose is to show the parts including the double walls.

[0036] (Double wall: right wall) First, the structure of the right wall 200 (AA part in FIG. 7) will be described with reference to Fig. 2. As shown in Fig. 2, the right wall 200 constitutes the right side surface of the bracket 6, and extends in the vertical direction from the aiming support part 93 provided at the upper right corner to the aiming support part 92 provided at the lower right corner connected to the lower wall 300.

[0037] The right wall 200 is configured as a double wall in its entirety, and includes a right wall main body 201 that defines the outer shape of the bracket 6, and a right auxiliary wall 202 that is disposed inside (to the left) thereof. The right wall main body 201 and the right auxiliary wall 202 are arranged side by side in the left-right direction, have substantially the same and uniform plate thickness, and extend in the front-rear direction. For this reason, when viewed from the front, only the end faces of the right wall main body 201 and the right auxiliary wall 202 are visible. In addition, both the right wall main body 201 and the right auxiliary wall 202 are surfaces that are curved in opposing directions and extend in the up-down direction. In addition, the wall surfaces of the right wall main body 201 and the right auxiliary wall 202 are free-form surfaces that extend by extruding a free curve in the front-rear direction. The right wall 200 of the bracket 6 is configured as a double wall by the right wall main body 201 and the right auxiliary wall 202.

[0038] The right auxiliary wall 202 extends downward from the left edge wall 93b of the aiming support part 93 at the upper right corner so as to extend the left edge wall 93b, and is connected to the lower wall 300. The right auxiliary wall 202 extends in the front-rear direction along the left side of the outer circumferential edge of the aiming support part 93, and constitutes the left edge wall 93b of the aiming support part 93. In addition, the wall that defines the upper end part of the right wall 200 extends in the front-rear direction along the lower side of the outer circumferential edge of the aiming support part 93, and constitutes the lower edge wall 93a of the aiming support part 93.

[0039] The right wall main body 201 and the right auxiliary wall 202 are arranged side by side in the left-right direction, but the center of the right wall main body 201 curves leftward, and the center of the right auxiliary wall 202 curves slightly rightward. Therefore, the right wall 200 has a narrowed shape in the center, and the distance between the right wall main body 201 and the right auxiliary wall 202 is shortest at the center and slightly longer at the top and bottom.

[0040] As shown in Figures 2 and 3, an inter-wall space extending in the front-rear direction is formed between the right wall main body 201 and the right auxiliary wall 202, which extend in the up-down direction. In the inter-wall space, right partition walls 241-243 are provided so as to cross between the right wall main body 201 and the right auxiliary wall 202. The right partition walls 241-243 extend in the left-right direction and divide the inter-wall space into four small spaces AR201-AR204 extending in the front-rear direction. As can be seen from Figure 9(A) described later, the small spaces AR201-AR204 are arranged side by side in the up-down direction.

[0041] The right partition walls 241-243 have a constant thickness, like the other walls, and the wall surfaces of each wall have opposing free-form surfaces extending in the front-rear direction. The right partition walls 241-243 are designed so that only the front end faces are visible when viewed from the front.

[0042] In this way, in the cylindrically formed bracket 6, by making a part of the outer peripheral wall 10 that defines the outer shape into a double wall, the right partition walls 241-243 are provided which further divide the inter-wall space formed between the double walls extending in the vertical direction, thereby improving the load-bearing performance of the right wall 200 in multiple directions. By providing the right partition walls 241-243 in the right wall 200, the amount of deformation due to the load on the right wall 200 can be reduced, and the rigidity of the bracket 6 is improved.

[0043] As shown in FIG. 9(A), in this embodiment, right inner walls 251-254 are provided to connect the lower edge wall 93a of the aiming support 93 with the right partition wall 241, the right partition wall 241 and the right partition wall 242, the right partition wall 242 and the right partition wall 243, and the right partition wall 243 and a lower wall main body 301 described later, so as to divide the right small spaces AR201-AR204 extending in the front-rear direction into the front and rear of the bracket 6. The right inner walls 251-254 are arranged shifted in the front-rear direction so as to be alternately arranged in the front-rear direction. Specifically, the right inner walls 251-254 are provided so as to close either the front opening or the rear opening of the right small spaces AR201-AR204, and each right inner wall 251-254 is formed so as to close the openings in different directions between adjacent small spaces. It should be noted that the term "closing" does not necessarily mean that each of the small spaces AR201 to AR204 is entirely closed, and includes partial closing.

[0044] Specifically, of the four right small spaces AR201 to AR204 arranged vertically, the first right small space AR201, which is the first from the top, and the third right small space AR203, which is the third from the top, are formed with a first right inner wall 251 and a third right inner wall 253, respectively, so as to close the rear opening. Also, the second right small space AR202, which is the second from the top, and the fourth right small space AR204, which is the fourth from the top, are formed with a second right inner wall 252 and a fourth right inner wall 254, respectively, so as to close the front opening.

[0045] In this way, the right inner walls 251-254 are formed so as to alternately close the openings of the four right small spaces AR201-AR204 partitioned by the right partition walls 241-243. Therefore, the cross-sectional shape of the right wall 200 is formed by connecting the right inner walls 251-254 extending in the vertical direction to the front end face or rear end face of the wall, which is the lower edge wall 93a, which is a substantially horizontal surface, the right partition walls 241-243, and the bottom wall 300, in order from the top, and is formed in a zigzag pattern so that the angular S-shapes are continuous. In addition, the left and right end faces of the right partition walls 241-243 and the right inner walls 251-254 are all connected to the right wall main body 201 and the right auxiliary wall 202 and integrated, so that the right wall 200 has a very strong shape. In addition, the right inner walls 251 to 254 are not necessarily arranged to close the openings of each small space at the front or rear end in the fore-and-aft direction of the bracket 6, but may be arranged, for example, to close the openings of each small space at the middle part in the fore-and-aft direction of the bracket 6.

[0046] The right wall 200 is composed of right partition walls 241-243 that cross the inter-wall space between the right wall main body 201 and the right auxiliary wall 202 that constitute a double wall extending in the vertical direction, and right inner walls 251-254 that are arranged approximately perpendicular to both the right wall main body 201, the right auxiliary wall 202, and the right partition walls 241-243 that constitute the double wall. The right wall 200 has a bridge structure in which the right inner walls 251-254 support the right partition wall, and the surfaces extending in three directions that are approximately perpendicular to each other are connected and formed as an integral unit, so that the right wall 200 has high load-bearing performance and strain-resistance performance in multiple directions. As a result, the rigidity of the bracket 6 is also improved by improving the load-bearing performance of the right wall 200. The same effect is also shown for other double walls described below.

[0047] (Double wall: lower wall) Next, the double wall portion (BB portion in FIG. 7) of the lower wall 300 will be described in detail. As shown in FIG. 2, the lower wall 300 is configured to include a lower wall main body 301 that defines the outer shape of the bracket 6, and a lower auxiliary wall 302 that is disposed inside (above) it. The right end portion of the lower auxiliary wall 302 is bent toward the lower wall main body 301 and connected to the lower wall main body 301, and only a portion of the lower wall 300 is configured as a double wall, not the entire area of ​​the lower wall 300. The lower wall 300 is a double wall from the storage space SP1 to the storage space SP2.

[0048] The lower wall main body 301 and the lower auxiliary wall 302 are formed to extend in the front-rear direction, so that when viewed from the front, only the front end faces of the lower wall main body 301 and the lower auxiliary wall 302 are visible.

[0049] The space inside the double walls of the bottom wall 300, i.e., the inter-wall space sandwiched between the bottom wall main body 301 and the lower auxiliary wall 302, is a flat, approximately rectangular parallelepiped that is long in the left-right direction. The lower partition walls 341-343 are provided to partition this elongated space in the left-right direction. That is, the lower partition walls 341-343 are provided to divide the inter-wall space between the double walls of the bottom wall 300 into a plurality of small spaces extending in the front-rear direction. The lower partition walls 341-343 are also provided to cross between the bottom wall 300, which is a double wall. The lower partition walls 341-343 extend in the up-down direction between the bottom wall main body 301 and the lower auxiliary wall 302, and are connected to the bottom wall main body 301 and the lower auxiliary wall 302.

[0050] The lower partition walls 341 to 343 are provided so as to be inclined from the vertical direction, and are provided so that the ends of adjacent partition walls are in contact with each other. That is, among the three lower partition walls 341, 342, and 343 arranged in order from the left, the first lower partition wall 341 arranged at the leftmost position is provided so as to be inclined from the vertical direction to the right. The second lower partition wall 342 is provided so as to be inclined from the vertical direction to the left, with its upper end connected to the upper end of the first lower partition wall 341. The third lower partition wall 343 is provided so as to be inclined from the vertical direction to the right, with its lower end connected to the lower end of the second lower partition wall 342. The three lower partition walls 341 to 343 are arranged so as to be inclined alternately, so that the end faces are configured in an N-shape when viewed from the front. That is, the three lower partition walls 341 to 343 are arranged in a truss shape.

[0051] In this way, the partition walls do not need to be approximately perpendicular to the double walls or be arranged approximately parallel to each other, but only need to be connected between the double walls and to the two walls that make up the double walls. It is more preferable to arrange the partition walls in a truss shape, as in the three lower partition walls 341 to 343, because this improves the load-bearing capacity.

[0052] 2, the lower wall main body 301 and the lower auxiliary wall 302 extend in the left-right direction but do not need to extend horizontally, and are bent at the points where they connect to the partition walls, and the walls are free-form surfaces made up of a plurality of slightly curved surfaces. All of the partition walls 341 to 343 and the lower wall 300 have approximately the same plate thickness and are provided extending along the front-rear direction.

[0053] As described later, at least a portion of the left intermediate wall 500 is also configured as a double wall. The left intermediate wall 500 is provided such that the left intermediate wall main body 501 and the left intermediate auxiliary wall 502 are substantially perpendicular to the lower auxiliary wall 302 and further extend to the inside of the double wall of the lower wall 300 and are connected to the lower wall main body 301. For this reason, the lower end portion of the left intermediate wall 500, more specifically, the portions of the left intermediate wall main body 501 and the left intermediate auxiliary wall 502 on the inside of the double wall of the lower wall 300, are also configured as a part of the partition wall of the lower wall 300.

[0054] In this way, two double walls may intersect, with one auxiliary wall forming part of the other's partition wall or peripheral wall, or conversely, one partition wall forming part of the other's auxiliary wall. Double walls are more rigid than single walls, and by intersecting and forming an integral structure with each other, they reinforce each other and further increase the rigidity of bracket 6.

[0055] In the space between the double walls of the lower wall 300, five small spaces, lower small spaces AR301-AR305, are defined by lower partition walls 341, 342, 343 and a left intermediate wall 500 that extends further into the lower wall 300. In these lower small spaces AR301-AR305 inside the lower wall 300, lower inner walls 351-355 that close openings alternately in the front-rear direction are provided, similar to the right wall 200.

[0056] Specifically, as shown in Figures 2 to 5 and 9(B), among the five lower small spaces AR301 to AR305 arranged in the left-right direction, the first lower small space AR301, the third lower small space AR303, and the fifth lower small space AR305 are formed with a first lower inner wall 351, a third lower inner wall 353, and a fifth lower inner wall 355 so as to close the rear openings. Also, the second lower small space AR302, the second lower small space AR302, and the fourth lower small space AR304 are formed with a second lower inner wall 352 and a fourth lower inner wall 354 so as to close the front openings.

[0057] The cross-sectional shape of the lower wall 300 is such that, arranged from left to right, the left wall 400, lower partition walls 341, 342, 343, and the left intermediate wall main body 501 and left intermediate auxiliary wall 502 of the left intermediate wall 500 are connected at their ends in a continuous manner by lower inner walls 351, 352, 353, 354, 355 which connect in the left-right direction, forming a continuous angular S-shape.

[0058] In addition, the upper ends of the lower partition walls 341-343 and the lower internal walls 351-355 are connected to the lower auxiliary wall 302 and the lower ends are connected to the lower wall main body 301, so that the lower wall 300 has a very strong structure. This improves the load-bearing capacity of the lower wall 300 and also improves the rigidity of the bracket 6.

[0059] As described above, the partition wall needs only to extend in the same direction as the double wall (front-to-back direction), be provided to separate the space of the double wall, and have both end faces connected to both constituent faces of the double wall, and need not be substantially perpendicular to the double wall, nor need they be provided parallel to each other, and there are no restrictions on the form, number, or shape of the partition wall. The internal wall does not need to completely close the small space as long as it is provided within the small space and has both end faces connected to the partition walls that form the small space. The internal wall, like the other walls, may be a curved surface, a bent surface, or a free-form surface.

[0060] (Double wall: left intermediate wall, right intermediate wall) Next, the left intermediate wall 500 (part CC in FIG. 7) will be described in detail. Like the right wall 200, the left intermediate wall 500 is also configured as a double wall. As shown in FIG. 6, the left intermediate wall 500 extends in the up-down direction. The left intermediate wall 500 is configured as a double wall including a left intermediate wall main body 501 and a left intermediate auxiliary wall 502 aligned in the left-right direction.

[0061] The inside of the double walls of the left intermediate wall 500, i.e., the inter-wall space sandwiched between the left intermediate wall main body 501 and the left intermediate auxiliary wall 502, is a flat, approximately rectangular prism that is long in the vertical direction, and left intermediate partition walls 541, 542 are provided to divide this elongated space in the vertical direction into three left intermediate small spaces AR501, AR502, AR503 that are aligned in the vertical direction.

[0062] Of the left middle small spaces AR501, AR502, and AR503, the first left middle small space AR501 located at the top does not have an internal wall. The second left middle small space AR502 located in the center is provided with a first left internal wall 551 that closes the front opening. The third left middle small space AR503 located at the bottom is formed with a second left internal wall 552 that closes the rear opening.

[0063] The left intermediate wall main body 501, the left intermediate auxiliary wall 502, and the left intermediate partition walls 541, 542 are provided extending in the front-rear direction, and when viewed from the front, only the front end faces of the walls can be seen. These front end faces have a uniform thickness, but are free-form, being curved or bent at multiple points.

[0064] For example, the upper part of the left intermediate auxiliary wall 502 is connected to the upper wall 100 at a considerable incline to the right. Therefore, the left intermediate auxiliary wall 502 cooperates with the left intermediate partition wall 541 to function as a rib between the left intermediate wall main body 501 and the upper wall 100. In addition, since the boss forming portion 71 is disposed in the left intermediate wall 500 so as to extend inward, the left intermediate auxiliary wall 502 at the portion where the boss 7 is provided is curved in an arc shape so as to follow the outer periphery of the boss forming portion 71. As a result, the boss forming portion 71 of the left intermediate auxiliary wall 502 functions as a part of the boss. The second left intermediate partition wall 542 is formed so as to connect the curved portion of the left intermediate auxiliary wall 502 and the lower auxiliary wall 302.

[0065] 10(A), the vertical cross-sectional shape of the left intermediate wall 500 is basically a shape of a series of angular S-shapes, although the boss forming portion 71 is formed. As described above, the left intermediate wall 500 having such a shape has high load-bearing performance in multiple directions and high rigidity.

[0066] It is not necessary to provide an intermediate wall in all of the small spaces formed inside the double walls, as in the case of the left intermediate wall 500. Also, as shown in Fig. 10(A), a boss forming portion 71, which is a through-hole forming portion, may be provided in the wall constituting the double walls. In this embodiment, the lower part of the left intermediate wall 500 is integrated with the lower wall 300. In addition, the upper part of the left intermediate auxiliary wall 502 is provided at an incline, so that it also functions as a double wall for the upper wall 100. In this way, by forming the wall into a free-form surface, it is possible to form a wall that fulfills two or more roles.

[0067] Furthermore, internal walls do not need to be provided in all of the small spaces contained in the space between the double walls, and the formation of internal walls may be omitted if the necessary rigidity can be ensured. By configuring the walls that define the shape of the bracket 6 with double walls and further dividing the space between the walls into small spaces and making it possible to decide whether or not to provide an internal wall in each small space, it is possible to provide the minimum number of internal walls necessary to ensure the necessary rigidity, and therefore it is possible to reduce the weight of the bracket 6.

[0068] Although the right intermediate wall 600 has a small area, it is configured as a double wall like the left intermediate wall 500. As shown in Fig. 6, the right intermediate wall 600 extends in the up-down direction. The right intermediate wall 600 is configured as a double wall including a right intermediate wall main body 601 and a right intermediate auxiliary wall 602 arranged side by side in the left-right direction, and has the same effects as the left intermediate wall 500 described above.

[0069] (Double wall: upper wall) Next, the right region of the upper wall 100, more specifically, the shape of the upper wall 100 of the storage space SP3 formed on the right side will be described.

[0070] As shown in Figure 2, the upper wall 100 has an upper wall main body 101 that constitutes part of the outer shape of the bracket 6, a first upper auxiliary wall 102 and a second upper auxiliary wall 103 that are formed with an inclination downward and to the right from the horizontal so as to connect the upper wall main body 101 and the right wall 200, and three auxiliary walls, a third upper auxiliary wall 104, a fourth upper auxiliary wall 105 and a fifth upper auxiliary wall 106, that are formed with an inclination downward and to the left from the horizontal so as to connect the upper wall main body 101 and the right intermediate wall 600.

[0071] In the upper wall 100, a plurality of auxiliary walls 102, 103 are provided at different angles, intersect with each other and are integrated, and the auxiliary walls are also configured as partition walls. By providing a plurality of auxiliary walls, at least a portion of the upper wall 100 is configured as a double wall, and further a portion of that is configured as a triple wall. In this way, the outer peripheral wall 10 may be provided with a plurality of auxiliary walls, and at least a portion of it may be configured as a multiple wall having three or more layers.

[0072] On the inside of the upper wall 100, an inter-wall space defined by the upper wall main body 101 and the upper auxiliary walls 102-106 is partitioned by the upper auxiliary walls 102-106 to form eight small spaces, namely upper small spaces AR101-AR108.

[0073] Some of the eight upper small spaces AR101 to AR108 are formed with inner walls that close the front opening or rear opening. In this embodiment, as shown in Figs. 2 to 5, a second upper inner wall 152 is formed so as to close the front opening of the central fourth upper small space AR104 defined by the first upper auxiliary wall 102, the second upper auxiliary wall 103, the third upper auxiliary wall 104, and the fourth upper auxiliary wall 105. The first upper small space AR101 and the eighth upper small space AR108 formed adjacent to the top and bottom of the fourth upper small space AR104 are formed with a first upper inner wall 151 and a third upper inner wall 153, respectively, so as to close the rear opening.

[0074] The upper wall 100 is provided with a plurality of intersecting auxiliary walls, each of which also acts as a partition wall, so that at least a portion of the upper wall 100 is configured as a double wall.

[0075] 10(B), the cross-sectional shape of the portion where the inner wall of the left intermediate wall 500 is provided is a continuous rectangular S-shape. As described above, the upper wall 100 configured in this manner has high load-bearing performance in multiple directions and high rigidity.

[0076] Like the upper wall 100, it is not necessary to specify where the internal walls are provided or not provided in the small spaces AR101 to AR108 formed in the double wall. An internal wall may be provided in any of the small spaces according to the required rigidity and weight reduction, or no internal wall may be provided at all.

[0077] There is no particular limitation as to which parts of the outer peripheral wall 10 of the bracket 6 are configured as double walls, but it is preferable to configure them to reinforce parts that are particularly subject to load, such as the aiming support parts 91-93, the boss forming parts 71-74, and the areas around the mounting members 81-84, since this greatly improves the rigidity of the bracket 6.

[0078] The aiming support portions 91 to 93 and the boss formation portions 71, 72, and 74, which are the main features of the bracket 6 according to this embodiment, will be described in detail below.

[0079] (Aiming support part) Here, the structure around the aiming supports 91-93 will be described in detail with reference to Figs. 2-5 and Fig. 11(B). Fig. 11(B) is a cross-sectional view taken along the line FF in Fig. 8. It mainly shows the boss forming portion 71 and the mounting member 82. As described above, the aiming supports 91-93 are formed at three corners of the bracket 6, namely, the lower left corner, the lower right corner, and the upper right corner. The aiming supports 91-93 are each a rectangular flat plate, and through holes 91c-93c having a shape similar to the outer shape of the aiming supports 91-93 are formed at approximately the center of the aiming supports. In addition, the aiming supports 91-93 are provided with edge walls 91a, 91b, 92a, 92b, 93a, and 93b extending forward from the plane of the aiming support 91 at the periphery thereof.

[0080] Specifically, the aiming support 91 includes an upper edge wall 91a extending in the left-right direction and a right edge wall 91b extending in the up-down direction. The aiming support 92 includes an upper edge wall 92a extending in the left-right direction and a left edge wall 92b extending in the up-down direction. The aiming support 93 includes a lower edge wall 93a extending in the left-right direction and a left edge wall 93b extending in the up-down direction. As shown in FIG. 2 and other figures, the aiming support 93 is provided in contact with the right end of the upper wall 100 and the upper end of the right wall 200. As described above, the right end of the upper wall 100 and the upper end of the right wall 200 are configured as double walls. For this reason, the lower edge wall 93a, which is the peripheral portion of the aiming support 93, shares a wall surface with the upper end wall of the right wall 200, and the left edge wall 93b shares a wall surface with the right end wall of the upper wall 100. The upper end wall of the right wall 200 and the right end wall of the upper wall 100 are portions configured as a double wall. In this manner, the left edge wall 93b is continuous with the right auxiliary wall 202, and the lower edge wall 93a is continuous with the fifth upper auxiliary wall 106, and the right auxiliary wall 202 and the fifth upper auxiliary wall 106 intersect at the lower left corner of the aiming support portion 93. As a result, the aiming support portion 93 is supported by four walls at the lower left corner.

[0081] For example, in the bracket 6 of this embodiment, the right wall 200 and the lower wall 300 connecting the three aiming support parts 91 to 93 are configured as double walls. In addition, the double wall part of the upper wall 100 is a small space extending toward the aiming support part 93 on the upper right, and the double wall part from the left intermediate wall 500 toward the lower wall 300 is a small space extending toward the aiming support part 91 on the lower left. Since the bracket 6 is supported at three points where the aiming support parts 91 to 93 are provided, the upper right, lower right, and lower left corners are particularly parts where a load is applied, and the parts connected to these are mainly configured as double walls. By providing double walls at the parts where a load is applied, it is possible to suppress an increase in mass due to the provision of double walls, and appropriately improve the rigidity of the bracket 6.

[0082] 11(A) is a cross-sectional view taken along line EE in FIG. 8. FIG. 8 is a front view of only the bracket 6, but FIG. 11(A) shows two aiming support parts 92, 93 formed mainly at the upper right and lower corners of the bracket 6 in a state in which the aiming screws E2, E3 are attached. For convenience, the cross-section is taken along a plane passing through the center of the aiming screws from line EE in FIG. 8.

[0083] Using FIG. 11(A), the aiming supports 92 and 93 will be mainly described, but the same applies to the aiming support 91. The aiming supports 91 to 93 are configured so that their respective plate surfaces are parallel. As shown in FIG. 11(A), the aiming screw E3 is fitted to the corresponding aiming support 93 by a mount M10, and the aiming screw E3 screwed into this mount M10 is inserted into the through hole 93c and locked. Reference E12 denotes an actuator for the aiming screw. The same applies to the aiming support 92. The bracket 6 is supported on the rear surface of the lamp body 2 so that the optical axes of the lamp units LU1 to LU3 can be adjusted.

[0084] Incidentally, for example, Patent Document 1 discloses a conventional bracket that extends as a surface in the left-right direction when viewed from the front and has an aiming support portion. The bracket disclosed in Patent Document 1 has a basic configuration of a flat plate when viewed from the front. For this reason, the aiming screw mounting portions are provided at three corners on the flat surface of the bracket. Although omitted in Patent Document 1, in a bracket of this shape, a standing wall that surrounds the through hole and protrudes rearward is provided on the back side of the through hole that serves as the aiming screw mounting hole. This configuration is used to provide the necessary rigidity around the aiming screw mounting hole, but the additional standing wall increases the weight.

[0085] On the other hand, in this embodiment, the aiming support parts 91 to 93 are provided so as to share a wall surface with the double wall which is a part of the outer peripheral wall 10. These shared walls (i.e., the edge walls 91a, 91b, 92a, 92b, 93a, 93b) all constitute a part of the outer peripheral wall 10 which constitutes the outer shape of the bracket 6, and are not added. Therefore, according to the bracket 6 according to the embodiment, it is not necessary to provide an additional standing wall in the aiming support parts 91 to 93, and the weight is not increased. In addition, the outer shape of the aiming support parts 91 to 93 is approximately similar to the through holes 91c to 93c which are aiming screw mounting holes formed approximately in the center. This is particularly preferable because the aiming support parts 91 to 93 can be configured in the smallest size compared to the case where they are not configured otherwise. Furthermore, by making the shape of the aiming support 91 similar to that of the through hole 91c, the distance from the peripheral side surface of the through hole 91c where the load is actually applied to the end face is approximately the same, so there is no bias in the moment and the load is applied approximately uniformly to the end face of the aiming support 91. For this reason, the stress applied to the base end portion of the aiming support 91 is distributed approximately evenly, making it possible to suppress breakage due to uneven distribution of stress.

[0086] (Boss forming part) Next, the boss forming portions 71, 72, 74 which are through hole forming portions will be described with reference to Figs. 2 to 6 and Fig. 11(B). As shown in Figs. 2 to 6, the boss forming portions 71, 72, 74 have a substantially circular flat plate shape and have through holes 71a, 72a, 74a in the center which are similar in shape to the boss forming portions 71, 72, 74. The boss forming portions 71, 72, 74 are configured such that the walls constituting the double wall of the outer peripheral wall 10 or the intermediate wall extend in the front-rear direction along the circular outer peripheral edge of the boss forming portions 71, 72, 74 and share a wall surface.

[0087] The boss forming portion 71 is provided in a portion of the left intermediate wall 500 configured as a double wall having a left intermediate wall main body 501 and a left intermediate auxiliary wall 502 so as to share a wall surface of the left intermediate auxiliary wall 502 as a wall surface extending in the front-rear direction along the outer circumferential edge of the boss forming portion 71. In other words, the position where the boss forming portion 71 is provided in the left intermediate auxiliary wall 502 is curved in an arc shape so as to follow the outer circumferential edge of the boss forming portion 71.

[0088] As a result, the left intermediate auxiliary wall 502 constituting the left intermediate wall 500 shown in FIG. 11(B) functions as the boss forming portion 71, i.e., as a part of the boss. A typical boss is formed in a flat plate-like member, and has a circular through hole for inserting a fixing member such as a bolt, and a cylindrical standing wall surrounding the through hole and protruding from the flat plate-like member. Such a standing wall increases the strength and rigidity near the boss, but also increases the weight. However, according to the above configuration, the wall surface of the left intermediate wall 500 for defining the storage space SP2 of the lamp unit is configured to follow the outer periphery of the boss forming portion 72, and functions like the standing wall of the boss. Therefore, there is no need to provide an additional standing wall, and it is possible to increase the strength and rigidity without increasing the weight.

[0089] According to the above configuration, the boss forming portions 71, 72, and 74 do not protrude from a flat wall, but can be provided on a wall surface extending in the same direction as the boss mounting direction (the extension direction of the through hole; in this embodiment, the front-rear direction). Generally, since the boss is cylindrical, it can only contact a plane extending in the same direction as the extension direction of the boss hole (through hole) at one point, and an enlarged portion must be provided to fill the gap between the horizontal surface and the boss. As described above, the base end of the mounting portion that is not similar in shape to the through hole is subject to a large moment and is prone to breakage. By providing the left intermediate auxiliary wall 502, which is integrated with the boss forming portion 71, so as to surround the outer periphery of the boss forming portion 71, the distance between the through hole 71a and the wall surface becomes approximately the same distance, and the moment acting on the boss forming portion 71 becomes approximately uniform. In addition, the wall surface is curved to match the peripheral wall surface, thereby increasing the contact area between the wall surface and the boss forming portion 71, and the load on the end surface can be further distributed.

[0090] Moreover, the boss forming portion 71 is adapted to contact the three left intermediate small spaces AR501-AR503 within the left intermediate wall 500. That is, the boss forming portion 71 is disposed at a position in the left intermediate wall 500 where the left intermediate auxiliary wall 502, the first left intermediate partition wall 541, and the second left intermediate partition wall 542 are connected. As a result, the boss forming portion 71 is supported by the four walls, and sufficient load resistance is ensured.

[0091] The boss forming portion 72 is provided in a portion of the lower wall 300 configured as a double wall including the lower wall main body 301 and the lower auxiliary wall 302, and in a portion of the right intermediate wall 600 configured as a double wall including the right intermediate wall main body 601 and the right intermediate auxiliary wall 602, so that the wall surfaces of the lower auxiliary wall 302 and the right intermediate wall main body 601 are shared as wall surfaces along the outer periphery of the boss forming portion 72. The positions where the boss forming portions 72 of the right intermediate wall 600 and the lower auxiliary wall 302 are provided are curved in an arc along the outer periphery of the boss forming portion 72, so that the arc-shaped portions of the lower auxiliary wall 302 and the right intermediate wall main body 601 function the same as the standing wall of the boss. Therefore, the structure near the boss forming portion 72 can achieve the same effect as the structure near the boss forming portion 71, that is, it is possible to increase the strength and rigidity without increasing the weight.

[0092] Like the boss forming portion 71, the boss forming portion 72 is integrated with the outer peripheral edge of the boss forming portion 72, and the right intermediate wall 61 and the lower auxiliary wall 302 are provided so as to surround the outer peripheral edge. The boss forming portion 72 is provided at the orthogonal portion of the right intermediate wall 600 and the lower wall 300, and is supported by both walls, which are double walls, to improve its rigidity. In addition, the lower inner wall 355 is provided approximately perpendicular to the lower auxiliary wall 302, to improve the rigidity of the lower auxiliary wall 302 and the rigidity of the boss forming portion 72.

[0093] Similarly, the boss forming portion 74 is provided in a portion of the right wall 200 configured as a double wall including a right wall main body 201 and a right auxiliary wall 202, with the wall surface of the right auxiliary wall 202 being provided along the outer periphery of the boss forming portion 74 so as to surround the outer periphery of the boss forming portion 72. As a result, the arc-shaped portion of the right auxiliary wall 202 functions the same as a so-called standing wall of a boss. The boss forming portion 74 is also in contact with a plurality of small spaces. As a result, the boss forming portion 74 can achieve the same effect as the boss forming portions 71 and 72.

[0094] It should be noted that boss formation portion 73 does not have the features described for boss formation portions 71, 72, and 74. That is, boss formation portion 73 is provided so as to protrude from upper auxiliary wall 102 toward accommodation space SP3, but its outer shape is not substantially similar to the shape of the through hole, and instead has enlarged portion 73b so as to follow the curved surface of the wall surface of upper auxiliary wall 102 from a shape substantially similar to the through hole. In this way, in bracket 6, it is not necessary for all boss formation portions to have the advantageous features described above, and the features may be adopted only in necessary locations.

[0095] (simulation) In order to confirm the effect of the bracket 6 configured as above, a simulation of mass and maximum displacement was performed using the bracket 6 and a conventional bracket having a flat back wall in front view and no portion configured as a double wall. As a result, the bracket 6 had a mass 24% smaller than the conventional product, and the maximum displacement when stress was applied was 60% smaller. By applying the above configuration, the bracket 6 according to this embodiment was lighter than the conventional product, and the rigidity was significantly improved.

[0096] (Molding method) Next, a molding process and a molding die for the bracket 6 configured as above will be described. Fig. 12 is a schematic diagram of the molding die for the bracket 6, and is an explanatory diagram for explaining the molding process. The cross-sectional line of the cross-sectional view of the die shown in Fig. 12 corresponds to the line AA in Fig. 8.

[0097] As shown in Fig. 12(A), first, the fixed mold 30 and the movable mold 40 are arranged facing each other and then clamped. The direction in which the mold is clamped / opened is defined as direction DR. In the clamped state, a molding space (cavity) CAV corresponding to the shape of the bracket 6 is defined inside the mold. The molding space CAV is provided so that the extension direction (front-rear direction) of the outer peripheral wall 10 of the corresponding bracket 6 coincides with the clamping direction DR.

[0098] 12(B), a resin material heated to a predetermined melting temperature is injected into the molding space CAV to fill the molding space CAV. The resin material filled in the molding space CAV is cooled and solidified, and the bracket 6 is formed.

[0099] Next, as shown in FIG. 12(C), the mold is opened, the movable mold 40 is moved away in the direction DR, and the bracket 6 attached to the fixed mold 30 is pushed out and removed by an ejection pin (not shown).

[0100] Since the bracket 6 is configured to extend along the mold opening direction DR, the movable mold 40 can be moved away from the fixed mold 30 along the direction DR without any problems. The bracket 6 is also pushed out from the fixed mold 30 along the direction DR and removed without any problems.

[0101] The bracket 6 is configured in a shape that extends in the front-to-rear direction, and the extension direction of the bracket 6 can be aligned with the mold opening direction DR of the mold, so that the bracket 6 can be molded by injection molding using a mold.

[0102] Although the bracket 6 has a complicated shape, it can be mass-produced by injection molding using a mold, resulting in high productivity.

[0103] The above describes preferred embodiments of the present invention.
