A ball shaft is provided integrally with a part of the lamp unit, and the ball shaft is fitted to a part of the lamp unit to be connected to the lamp unit. In particular, the aiming screw is screwed to the support bracket. There has been proposed a configuration that facilitates easy assembly.

JP 2008-123698 A German Patent Publication 102005037074

  With respect to the structure of the aiming part of Patent Document 2, particularly the support bracket, in order to support the support bracket so as to be movable in the front-rear direction of the lamp, support pieces are integrally formed on both sides of the support bracket. A configuration is adopted in which a slit provided in the piece is engaged with a support rail formed integrally extending on the inner wall of the lamp housing in the longitudinal direction of the lamp. Therefore, the weight of the connected lamp unit is applied to the support bracket, and further to the support rail via the support bracket support piece. When considering the strength reliability of the support piece and the support rail, It is necessary to form the support pieces and the support rails as being thick and strong. In particular, when the lamp unit is composed of a projector-type lamp unit having a large weight with a large projection lens, it is necessary to configure the support piece and the support rail to be strong enough to withstand the weight of the lamp unit. . On the other hand, in the case of a light reflector type lamp unit, the support piece and the support rail can be configured to be relatively small and light. Therefore, in a headlamp in which a projector-type lamp unit and a reflector-type lamp unit are mixed, designing and manufacturing a support bracket corresponding to each lamp unit increases the number of parts and is troublesome to manufacture and manage. It will be a thing. In addition, if a support bracket that can withstand heavy projector-type lamp units is designed and manufactured and applied to both lamp units, the design will be excessive for reflector-type lamp units, and the headlamps will be downsized. This is an obstacle to weight reduction.

  The object of the present invention is to enable the use of a support bracket having the same configuration even when the standards such as the weight of the lamp unit are different, and to simplify the design, manufacture and management by sharing the components including the support bracket. On the other hand, it is an object of the present invention to provide an aiming device for a vehicular lamp that makes it possible to construct a support structure having a necessary and sufficient strength corresponding to the difference in specifications of each lamp unit.

The present invention relates to a vehicular lamp including a lamp housing and a lamp unit incorporated in the lamp housing, a support bracket coupled to the lamp unit, and a support bracket that is screwed into the support bracket and rotated. An aiming device including an aiming screw for moving the bracket in the longitudinal direction of the lamp, wherein the support bracket includes a first sliding portion and a second sliding portion, and only the first sliding portion is inserted in the lamp housing. A first bracket holding body that slidably holds the support bracket in a state, and a second bracket that slidably holds the support bracket in a state where both the first sliding portion and the second sliding portion are inserted. It is characterized in that both or one of the holding bodies is selected and arranged.

  For example, the first bracket holding body is formed in a bowl shape for inserting the first sliding portion, and the second bracket holding body is formed in a cylindrical shape for inserting the first sliding portion and the second sliding portion. Is done.

  In the present invention, when a plurality of lamp units having different weights are installed in the lamp housing, the bracket holder of the low-weight lamp unit is constituted by the first bracket holder, and the lamp unit of the high-weight side. The bracket holder is composed of a second bracket holder. For example, the low weight side lamp unit is a reflector type lamp unit, and the high weight side lamp unit is a projector type lamp unit.

  In the support bracket according to the present invention, the first sliding portion, the second sliding portion, and the screwing portion to be screwed to the aiming screw are integrally formed, and the ball shaft that is connected to the lamp unit and constitutes the ball joint includes Installed. It is preferable that the 1st sliding part is provided with the elastic contact piece which elastically contacts the inner surface of a 1st bracket holding body or a 2nd bracket holding body.

  According to the present invention, both the first bracket holding body and the second bracket holding body that can hold the support bracket having the same configuration are selected, so that the second bracket holding body is high. The support bracket can be held with strength, and the first bracket holder can hold the support bracket in a space-saving manner. Therefore, the strength required without increasing the number of parts of the support bracket by appropriately selecting the first bracket holder and the second bracket holder depending on the structure, shape, weight, etc. of the lamp unit. In addition, an aiming apparatus that can be miniaturized as much as possible can be configured.

  Here, since the 2nd bracket holding body is formed in the cylinder shape which inserts both the 1st sliding part and the 2nd sliding part, two parts of the 1st sliding part and the 2nd sliding part The support bracket can be held on the bracket holder, and the support bracket can be held with high strength. The support bracket can be stably slid even in the case of a heavy-weight lamp unit. An aiming device can be configured. Since the first bracket holding body is formed in a bowl shape for inserting only the first sliding portion, a portion for holding the second sliding portion is unnecessary, and the second bracket is provided on the inner wall of the lamp housing. The space for forming the holding body can be reduced, which is advantageous in reducing the size of the lamp housing or the entire lamp.

  In the support bracket of the present invention, the first sliding portion and the second sliding portion are integrally formed, and can be held against both the first bracket holding body and the second bracket holding body. Therefore, even when the structure of the bracket holder is made different depending on the type of the lamp unit, the support bracket and other components having the same structure can be used. Therefore, it is not necessary to prepare support brackets having at least different configurations, and the design, manufacture, and parts management of the support brackets can be simplified. In particular, since the first sliding portion is provided with an elastic contact piece that elastically contacts the inner surface of the first bracket holding body or the second bracket holding body, the first sliding portion is elastic even when sliding with respect to any bracket holding body. It can be held in a stable state by the elastic contact force of the contact piece.

Further, the upper second sliding portion 432 is a pair of sleeve pieces 432a having a triangular frame shape projecting outward from both side surfaces of the screwing portion 433 and projecting from the tip ends upward. It is configured. The sleeves 431a and 432a of the first sliding portion 431 and the second sliding portion 432 have the same projecting dimensions to both outer sides. Further, when the support bracket 43 is viewed from the side surface direction, the second sliding portion 432 is displaced (offset) from the first sliding portion 431 toward the distal end direction of the aiming screw 44.

As shown in FIG. 5A, the ball bearing 41 is screwed to a part of the aiming flange 32 of the high beam lamp unit HLU, and the head 21 of the ball shaft 42 is fitted to the ball bearing 41. Is done. As a result, the support bracket 43 is connected to the aiming flange 32 so as to be tiltable. As shown in FIG. 2, the support bracket 43 is a first bracket holding body formed integrally with the lamp body 11 at a position directly below the aiming screw 44 on the rear wall 111 of the lamp body 11. The aiming screw 44 is screwed into the screwing portion 433 while being inserted and supported by the bracket holding body 51.

The bracket holder 51 for H is configured such that the first sliding portion 431 of the support bracket 43 is inserted therein. The bracket holder 51 for H is configured as a rod-like body having a required length of a single support structure that protrudes forward from the inner surface of the rear wall 111 of the lamp body 11 and has a front end opened. That is, the opening shape of the bracket holder 51 for H is a rectangular shape in which the top and bottom are short and slender to the left and right corresponding to the shape of the first sliding portion 431 of the support bracket 43, and both end edges are bent inward. It is formed as a body. In the support bracket 43, only the first sliding portion 431 is inserted into the bracket holder 51 for H from the opening, and as shown in FIGS. 5 (a) and 5 (b), Both end portions of the sleeve pieces 431a of the first sliding portion 431 are in contact with the inner side surfaces of the H bracket holding body 51, and holding in the left-right direction is performed. Further, the contact piece 431b provided on the lower end surface of the support bracket 43 contacts the inner bottom surface of the H bracket holding body 51, and two elastic contact pieces 431c provided on the same lower end surface elastically contact the inner bottom surface. By using this elastic contact force, the first sliding portion 431 is press-fitted in the vertical direction, so that stable holding in the vertical direction is performed.

The structure of the second aiming portion AIM2 of the aiming device for H H-AIM is the same as that of the support bracket 43 except that the arrangement position with respect to the high beam lamp unit HLU is arranged at a position different from the first aiming portion AIM1. And the structure of the bracket holder 51 for H is completely the same.

  The configuration of the fulcrum portion FUL, the first aiming portion AIM1, and the second aiming portion AIM2 of the H aiming device H-AIM is also substantially the same for the L aiming device L-AIM. That is, FIG. 6 is an exploded perspective view of the first aiming portion AIM1 of the L aiming device L-AIM, but the ball bearing 41 and the ball shaft 42 constituting the fulcrum portion FUL have the same configuration, and The aiming screw 44 and the support bracket 43 that constitute each of the second aiming portions AIM1 and AIM2 have the same configuration. Therefore, the same reference numerals are given to the same parts of the main configuration, and the detailed description is omitted.

On the other hand, the second bracket holding body for inserting and supporting the support bracket 43, here the L bracket holding body 52, is integrally formed from the rear wall 111 of the lamp body 11 toward the front of the lamp as shown in FIG. The projecting front end is configured as a cylindrical body having a required length with an opening. The opening shape of the bracket holder 52 for L is formed as a cylindrical body having a rectangular lower region and an arcuate upper portion so as to correspond to the outer contour of the support bracket 43. The aiming screw 44 is disposed inside. The support bracket 43 is inserted into the L bracket holding body 52 from the opening, and in this inserted state, as shown in FIGS. 7A and 7B, the first sliding portion 431 is inserted. And both end portions of the sleeve pieces 431a and 432a of the second sliding portion 432 are in contact with the respective inner side surfaces of the L bracket holding body 52 and are held in the left-right direction, and are in contact with the lower end surface of the support bracket 43. The piece 431b abuts against the inner bottom surface of the L bracket holding body 52, and two elastic contact pieces 431c provided on the same lower end surface are also elastically contacted with the inner bottom surface. The sliding portion 432 is press-fitted into the L bracket holding body 52 so as to be stably held in the vertical direction.

The structure of the second aiming portion AIM2 of the L aiming device L-AIM is also different from that of the first aiming portion AIM1 in that the arrangement position with respect to the low beam lamp unit LLU is different from the first aiming portion AIM1. And the structure of the bracket holder 52 for L is completely the same.

  The aiming adjustment by the H aiming device H-AIM and the L aiming device L-AIM configured as described above will be described. First, regarding the L aiming device L-AIM, when the aiming screw 44 is rotated by an operation outside the lamp housing 1, the support bracket 43 is screwed at the screwing portion 433 to increase the length of the aiming screw 44. The ball bearing 41, which is moved in the vertical direction and is fitted to the ball shaft 42 through the ball shaft 42, is moved in the lamp front-rear direction, and the low beam lamp unit LLU is tilted with the fulcrum portion FUL as a fulcrum. That is, the low beam lamp unit LLU is tilted in the vertical direction with the fulcrum part FUL as a fulcrum by adjustment in the first aiming part AIM1, and the low beam lamp unit LLU is fulcrum by adjustment in the first and second aiming parts AIM1 and AIM2. Tilt left and right with FUL as a fulcrum. This makes it possible to adjust the irradiation direction of the low beam lamp unit LLU.

At this time, in the support bracket 43, the first sliding portion 431 and the second sliding portion 432 are in sliding contact with the inner surface of the L bracket holding body 52, respectively, and the state in which the interior is supported in the L bracket holding body 52 is maintained. However, it is slid in the cylinder axis direction. For this reason, the support bracket 43 is supported in the left and right directions at the lower side and the upper side of the support bracket 43, so that the support bracket 43 can be stably held against the load in the rotational direction applied to the support bracket 43. Hold in. Further, the elastic contact piece 431c provided on the lower end surface of the support bracket 43 is brought into a state of being elastically contacted with the inner bottom surface of the L bracket holding body 52 and press-fitted in the vertical direction. It is possible to keep the holding in the up and down direction, which is heavy, in a stable state. Accordingly, the support bracket 43 is firmly held in each of the vertical direction and the horizontal direction, and the low beam lamp unit LLU is configured by a relatively heavy projector-type lamp unit. Even when added, the support bracket 43 can be held in a stable state, and the support bracket 43 can be smoothly moved along the aiming screw 44 during the aiming operation.

On the other hand, regarding the H aiming device H-AIM, it is the same as the L aiming device L-AIM that the support bracket 43 is moved in the longitudinal direction of the ramp when the aiming screw 44 is rotated. It is also the same that the ball bearing 41 fitted thereto is moved through the lamp 42 in the longitudinal direction of the lamp and the high beam lamp unit HLU is tilted with the fulcrum part FUL as a fulcrum. At this time, the support bracket 43 is slid in the cylinder axis direction in the H bracket holding body 51 while being supported internally with only the first sliding portion 431 in sliding contact with the inner surface of the H bracket holding body 51. At this time, vertical support is performed only when the elastic contact piece 431c provided on the lower end surface of the support bracket 43 is elastically contacted with the inner bottom surface of the bracket holder 51 for H. However, the high beam lamp unit HLU is a low beam lamp unit LLU. Compared to the above, since it is composed of a light reflector type lamp unit, the weight added to the support bracket 43 from the high beam lamp unit HLU is light even if the bracket holder 51 for H is formed in a bowl shape. The support bracket 43 is held in a stable state only by the interpolated state at the one sliding portion 431, and smooth movement is possible during the aiming operation. Therefore, the H bracket holding body 51 is formed more than the case where the H bracket holding body 51 is formed in a cylindrical shape in which the entire support bracket 43 is inserted and held like the L bracket holding body 52 of the L aiming device L-AIM. 51 can be made small and space-saving.

As can be seen from the description of this embodiment, even when configuring a plurality of aiming devices respectively corresponding to lamp units having different weights, it is only necessary to select either the cylindrical type or the saddle type configuration of the bracket holding body, Other components such as the aiming screw and the support bracket can be formed of the same component. Therefore, it is possible to share parts, and it is possible to reduce the number of parts and simplify parts design, manufacturing, and management. On the other hand, the support bracket can be stably held by appropriately selecting either the cylindrical shape or the saddle shape as the shape of the bracket holding body corresponding to the weight of the lamp unit, and a smooth aiming operation can be ensured. In particular, stable holding is possible even in the case of a heavy lamp unit, and in the case of a lightweight lamp unit, it is possible to reduce the space for mounting the bracket holder in the lamp housing and to reduce the size of the headlamp. It becomes possible. Furthermore, it is possible to improve the earthquake resistance of the lamp by absorbing vibration generated in the vehicle body by the elastic contact piece provided on the support bracket and transmitting it to the support bracket or the lamp unit.

In the embodiment, the L bracket holding body in the L aiming device is formed in a cylindrical shape, and the H bracket holding body in the H aiming device is formed in a bowl shape. Corresponding to the extent of the extra space inside, it is possible to adopt an arbitrary configuration of these bracket holders in a cylindrical shape or a bowl shape. Needless to say, the shape of the support bracket and the shape of the bracket holding body corresponding thereto can be appropriately changed. In particular, the left and right and up and down directions for arranging them do not necessarily have to be oriented in the vertical direction or the horizontal direction. In some cases, they are arranged in an inclined attitude corresponding to the arrangement state of the lamp unit in the lamp housing. It is also possible.

  The present invention can be applied to any vehicle lamp provided with an aiming device that adjusts the irradiation direction, regardless of differences in individual specific configurations.
