Description

  The present invention relates to a vehicular lamp. In particular, the present invention relates to a vehicular lamp that can be easily adjusted to the adjustment angle of the optical axis of a headlamp when an auxiliary headlamp is equipped with an optical axis adjustment mechanism.

  A conventional vehicular lamp is provided with an optical axis adjustment mechanism in a headlamp in order to improve visibility of a vehicle driver at night and to suppress glare on an oncoming vehicle or the like. Some of the optical axis adjustment mechanisms automatically adjust the optical axis using parts such as actuators. In such a vehicular lamp, the driver's visibility at night is improved in various ways according to the driving situation such as the speed of the vehicle and the inclination of the vehicle as described above. The optical axis is adjusted automatically. For example, in Patent Document 1, when the traveling lamp is turned on, the passing lamp is turned on simultaneously with the lighting of the traveling lamp, and the optical axis is adjusted by automatically adjusting the direction of the passing lamp. The optical axis of the traveling beam is brought closer to the optical axis of the passing beam. As a result, the portion where the traveling beam is brightly irradiated and the portion where the passing beam is irradiated brightly are close to each other, and the irradiation direction of the traveling lamp when the traveling lamp is turned on can be illuminated more brightly. The irradiation range can be visually recognized more clearly.

  However, among vehicle lamps, there is a technology in which the headlamp is equipped with the optical axis adjustment mechanism as described above, but there is no technology in which the auxiliary headlamp is equipped with the optical axis adjustment mechanism. . Since the auxiliary headlamp also illuminates the front, adjusting the optical axis of the auxiliary headlamp can improve the driver's visibility at night. If the adjustment angle of the optical axis with the headlamp is not matched, there is a risk of glare with respect to the oncoming vehicle. In addition, when adjusting the optical axis adjustment angle in this way, the actuators etc. that operate during optical axis adjustment are used as the same parts for the headlamp and auxiliary headlamp, and the actuators etc. are used for the same signal. By controlling by the above, it is possible to suppress an increase in manufacturing cost and to easily adjust the optical axis. However, since the headlamp and the auxiliary headlamp are generally different in size, the optical axis is adjusted if the technology of the optical axis adjustment mechanism of the headlamp is used for the auxiliary headlamp. In this case, the positional relationship, i.e., the fulcrum pitch, between the operating shaft, which is the center of the arc motion of the vehicular lamp, and the operating portion, which is a portion connecting the actuator, etc., is different. When the fulcrum pitch is different, the adjustment angle of the entire vehicular lamp with respect to the amount of operation input to the operating unit is different, so the same actuator as the headlamp is used when adjusting the optical axis of the auxiliary headlamp. In other words, the manufacturing cost increases and the optical axis adjustment becomes complicated.

  The present invention has been made in view of the above, and provides a vehicular lamp that can easily adjust the adjustment angle of the optical axis of the auxiliary headlamp to the adjustment angle of the optical axis of the headlamp. With the goal.

  In order to solve the above-described problems and achieve the object, a vehicular lamp according to the present invention is a vehicular lamp equipped with an optical axis adjustment mechanism, wherein the vehicular lamp is a headlight when mounted on a vehicle. A vehicle lamp serving as a lamp and a vehicle lamp serving as an auxiliary headlamp, and the optical axis adjusting mechanisms equipped in the headlamp and the auxiliary headlamp each have an operating shaft, The operating shaft of the headlamp is formed in a horizontal direction when the vehicle lamp is mounted on the vehicle, and the operating shaft of the auxiliary headlamp is mounted on the vehicle. Is formed obliquely with respect to the horizontal direction, the headlamp and the auxiliary headlamp are each provided with an operating portion, and further, operating means coupled to the operating portion, The operating means provided in the headlamp and the auxiliary headlamp The vignetting said actuating means, operating at the same signal, and characterized in that to the same signal has the same operation amount.

  In this invention, the adjustment direction of the optical axis of the auxiliary headlamp can be set to an oblique direction by forming the operating axis of the auxiliary headlamp in an oblique direction. Thus, the adjustment direction of the auxiliary headlamp can be set to an arbitrary direction by setting the adjustment direction of the optical axis of the auxiliary headlamp to an oblique direction. As a result, the forward visibility by irradiation with the auxiliary headlamp is improved, and the safety at the time of traveling at night in a vehicle equipped with the vehicle lamp can be improved. Also, if the vertical adjustment angle of the optical axis of the auxiliary headlamp is adjusted to the adjustment angle of the optical axis of the headlamp, the light from the auxiliary headlamp will be more glaring with respect to oncoming vehicles. In addition, by combining the irradiation range of the headlamp and the irradiation range of the auxiliary headlamp, it is possible to more reliably contribute to the improvement of safety during night driving. In this way, the adjustment angle in the predetermined direction of the optical axis of the auxiliary headlamp is adjusted to an arbitrary angle, for example, by adjusting the vertical adjustment angle of the optical axis of the auxiliary headlamp to the adjustment angle of the optical axis of the headlamp. When setting, it is possible to set the auxiliary headlamp at an arbitrary angle simply by forming the operating axis of the auxiliary headlamp in an oblique direction. As a result, the adjustment angle of the optical axis of the auxiliary headlamp can be easily adjusted to the adjustment angle of the optical axis of the headlamp.

  In addition, the operating shaft of the headlamp is formed in a horizontal direction, whereas the operating shaft of the auxiliary headlamp is formed in an oblique direction as described above, and thus is coupled to each operating portion. When adjusting the optical axes of the headlamp and the auxiliary headlamp by the operating means, the auxiliary headlamp operates in a direction different from the operating direction of the headlamp. For this reason, by adjusting and setting the direction of the operating axis of the auxiliary headlamp, the operating angle in the predetermined direction with respect to the operating amount of the operating means provided in the auxiliary headlamp can be set to an arbitrary angle. Can do. As a result, the adjustment angle in the predetermined direction of the optical axis of the auxiliary headlamp can be easily adjusted to the adjustment angle of the optical axis of the headlamp. In addition, since the operation angle in the predetermined direction with respect to the operation amount of the operation means of the auxiliary headlamp can be set to an arbitrary angle in this way, the adjustment angle of the auxiliary headlamp is set to the adjustment angle of the headlamp. In the case of matching, both actuating means are actuated by the same signal and have the same actuating amount for the same signal, that is, the same actuating means can be used. Further, since the same electrical signal is input to both the operating means, when there are a plurality of operating means, the control means for controlling the operating means can be simplified. As a result, even when adjusting the optical axes of headlights and auxiliary headlamps of different sizes, manufacturing is facilitated by sharing parts and simplifying the structure, thereby reducing manufacturing costs. Can do.

  Further, in the vehicular lamp according to the present invention, the headlamp and the auxiliary headlamp are more than the vertical width of the operating shaft and the operating portion of the headlamp when mounted on the vehicle. The longest part of the lengths of the operating part and the support part of the operating shaft in the vertical direction of the auxiliary headlamp is shorter.

  In this invention, the vertical width between the operating shaft and the operating portion of the headlamp, that is, the length of the operating portion in the vertical direction of the auxiliary headlamp and the support portion of the operating shaft is larger than the fulcrum pitch of the headlamp. The longest portion, that is, the fulcrum pitch of the auxiliary headlamp is formed shorter. These headlamps and auxiliary headlamps are each operated in the direction of rotation around the respective operating axis when the operating means is operated, and the direction of the lamp is changed to adjust the optical axis. . Even when the fulcrum pitch of the auxiliary headlamps operating in this way is shorter than the fulcrum pitch of the headlamps, the auxiliary headlamps are inclined in a direction different from the operating axis of the headlamps, that is, obliquely with respect to the horizontal direction. By setting the operating axis, the adjustment angles of the optical axes of the headlamp and the auxiliary headlamp in the vertical direction can be matched. In other words, when the fulcrum pitch is short, the rotation angle about the operating axis when the operating means is operated becomes large, but by adjusting the angle of the operating axis, the adjustment direction of the optical axis, that is, the vertical axis The directional working angle is substantially reduced. Thereby, the adjustment angles of both optical axes when the respective operating means coupled to both the vehicle lamps are operated with the same operation amount can be adjusted. As a result, the adjustment angle of the optical axis of the auxiliary headlamp can be more easily adjusted to the adjustment angle of the optical axis of the headlamp.

  The vehicular lamp according to the present invention has an effect that the adjustment angle of the optical axis of the auxiliary headlamp can be easily adjusted to the adjustment angle of the optical axis of the headlamp.

  5 is a cross-sectional view taken along the line CC of FIG. As with the headlamp 10, the fog lamp 40 is provided with a reflector 54 in a lamp chamber 53 defined by a lamp housing 51 and a lamp lens 52, and the headlamp 10 is located behind the lamp chamber 53. In the same manner, a pivot 56, a pivot receiver 57, a leveler 62, and a rod fixing portion 64 are provided. The leveler 62 having the rod 63 and the pivot 56 are fixed to the lamp housing 51, and the pivot receiver 57 having the engagement port 58 and the rod fixing part 64 having the engagement port 65 are also fixed to the reflector 54. The pivot 56 and the pivot receiver 57, and the rod 63 and the rod fixing portion 64 are provided in the reflector 54 or the lamp housing 51 at positions corresponding to each other, that is, positions where they can be engaged with each other.

The

  6 is a cross-sectional view taken along the line E-E in FIG. 5, and is a view showing both right and left fog lights of the vehicle as shown in FIG. 2. Two sets of the support portions 59 are provided in each fog lamp 40 of the fog lamp 40 provided on the left and right of the front portion of the vehicle 1. In the left fog lamp 41 that is the fog lamp 40 provided on the left side of the vehicle 1, the first support portion 60 that is one set of the support portions 59 of the two sets passes through the center of the insertion hole 67. It is located on the upper side of the center line 72 in the left-right direction toward the direction and on the right side of the center line 71 in the up-down direction passing through the center of the insertion hole 67. In addition, the second support portion 61 which is the other support portion 59 of the two sets is located below the left-right direction center line 72 and located to the right side of the up-down direction center line 71. Furthermore, it is located on the right side of the first support part 60. An imaginary axis passing through the first support portion 60 and the second support portion 61 becomes the operation shaft 66, and when adjusting the optical axis of the left fog lamp 41, the left side in the rotation direction about the operation shaft 66 is left. Adjustment is performed by operating the fog lamp 41.

  In addition, since the second support portion 61 is positioned below and on the right side of the first support portion 60 as described above, the operation shaft 66 is moved from the upper side to the lower side as it goes from the left side to the right side. It is formed in a downward direction, that is, tilted to the right. Thus, the operating shaft 66 of the left fog lamp 41 is formed at an angle different from that of the operating shaft 34 of the headlamp 10.

  The rod fixing portion 64 formed on the left fog lamp 41 is below the fog lamp 40, on the left side of the insertion hole 67, that is, below the horizontal center line 72 and from the vertical center line 71. Is also provided on the left side. The leveler 62 is provided at a position where the rod 63 can be engaged with the rod fixing portion 64, and the rod 63 of the levelizer 62 is positioned below the fog lamp 40 on the left side of the insertion hole 67. Is provided. Further, the rod fixing portion 64 and the rod 63 are provided so as to be positioned below the second support portion 61.

  The positions of the support portion 59, the rod fixing portion 64, and the leveler 62 of the right fog lamp 42 that is the fog lamp 40 provided on the right side of the vehicle 1 are centered on the vertical center line 71 with respect to the left fog lamp 41. Each is a line-symmetrical position. That is, the first support portion 60 is located above the left-right direction center line 72 and is located to the left side from the up-down direction center line 71. Further, the second support portion 61 is located below the left-right direction center line 72, located on the left side of the up-down direction center line 71, and further on the left side of the first support portion 60. positioned. The right fog lamp 42 also has an operating shaft 66 that is an imaginary axis passing through the first support portion 60 and the second support portion 61, similarly to the left fog lamp 41. For this reason, the operating shaft 66 of the right fog lamp 42 is formed so as to be inclined upward and symmetrical to the operating shaft 66 of the left fog lamp 41.

  Further, the rod fixing portion 64 formed on the right fog lamp 42 is below the right fog lamp 42, on the right side of the insertion hole 67, that is, below the horizontal center line 72, and in the vertical center line. It is provided on the right side of 71. The leveler 62 is provided at a position where the rod 63 can be engaged with the rod fixing portion 64, and the rod 63 of the leveler 62 is positioned below the fog lamp 40 and on the right side of the insertion hole 67. Is provided. Further, the rod fixing portion 64 and the rod 63 are provided so as to be positioned below the second support portion 61.

  As described above, the positional relationship between the rod fixing portion 64 of the fog lamp 40 and the first support portion 60 and the second support portion 61 is such that the rod fixing portion 64 is in the first support state when the fog lamp 40 is mounted on the vehicle 1. It is provided so that it may be located in the outside direction of the part 60 and the second support part 61. Further, the direction of inclination of the operating shaft 66 is inclined in a direction from the outside toward the inside as it goes from the top to the bottom in a state where the fog lamp 40 is mounted on the vehicle 1.

  Further, the fulcrum pitch K, which is the length in the vertical direction from the rod fixing portion 64 of the fog lamp 40 to the first support portion 60, is the operating shaft 34 of the headlamp 10 and the rod fixing portion of the headlamp 10. It is shorter than the fulcrum pitch J, which is the vertical width with respect to 32. That is, a direction parallel to the direction of the shortest distance than the vertical width between the operating shaft 34 and the rod fixing portion 32 of the headlamp 10, that is, the fulcrum pitch J which is the shortest distance between the operating shaft 34 and the rod fixing portion 32. Among the lengths of the fog lamp 40 in the vertical direction from the support portion 59 to the rod fixing portion 64, the fulcrum pitch K that is the length from the first support portion 60 to the rod fixing portion 64, which is the longest portion, is greater. It is short. The fog lamp 40 is thus equipped with an optical axis adjustment mechanism in a form different from the optical axis adjustment mechanism of the headlamp 10.

  The vehicular lamp according to the first embodiment is configured as described above, and the operation thereof will be described below. When the switch for the headlamp 10 provided in the vehicle is on the side for lighting the headlamp 10, the discharge bulb 15 of the headlamp 10 emits light, and the light from the discharge bulb 15 is reflected forward by the reflector 24. Then, the light passes through the lamp lens 22 and irradiates the front. Similarly, when the switch for the fog lamp 40 provided in the vehicle is on the side where the fog lamp 40 is lit, the discharge bulb 15 of the fog lamp 40 emits light, and the light from the discharge bulb 15 is reflected forward by the reflector 54. Then, the light passes through the lamp lens 52 and irradiates the front.

  When the front-rear direction of the vehicle 1 equipped with the headlamp 10 and the fog lamp 40 is tilted up and down with respect to the road surface, the headlamp 10 and the fog lamp are driven by the levelers 30 and 62 according to the tilt. 40 turns in the vertical direction. For example, when the front of the vehicle 1 is inclined upward with respect to the road surface, an inclination detection sensor (not shown) attached to the vehicle 1 detects the inclination, and the vehicle is detected according to the detected inclination. The lamp control unit sends an electrical signal to the leveler 30 of the headlamp 10. In response to this signal, the rod 31 of the levelizer 30 contracts. That is, the rod 31 of the leveler 30 of the headlamp 10 contracts according to the inclination detected by the inclination detection sensor.

  When the rod 31 contracts, the rod fixing portion 32 engaged with the rod 31 moves backward. The headlamp 10 operates by forming a plurality of support portions 29 including a support portion 29 formed by the pivot 26 and the pivot receiver 27 and a support portion 29 formed by the left-right direction optical axis adjusting device 36. The headlamp 10 is supported so as to be operable in a rotation direction in which the operation shaft 34 is a central axis of rotation. For this reason, when the rod fixing portion 32 moves rearward as described above, the entire headlamp 10 operates in the rotational direction in the direction in which the rod fixing portion 32 moves rearward with the operating shaft 34 as the central axis. That is, the reflecting surface 25 of the reflector 24 facing forward operates in a direction facing downward. Thereby, the irradiation light which irradiates the front is irradiated downward compared with before the operation | movement of the rotation direction of the headlamp 10. FIG.

  Thus, when the vehicle 1 is tilted and the leveler 30 of the headlamp 10 is activated, the same signal as the signal sent from the vehicle lamp control unit to the leveler 30 of the headlamp 10 is also sent to the leveler 62 of the fog lamp 40. . The leveler 62 of the fog lamp 40 that has received this signal from the vehicle lamp control unit operates in the same manner as the leveler 30 of the headlamp 10. That is, the rod 63 of the leveler 62 of the fog lamp 40 contracts by the same amount as the rod 31 of the headlamp 10. Since the operating shaft 66 of the fog lamp 40 is formed in an oblique direction, when the rod 63 of the leveler 62 is contracted, the operating shaft 66 becomes the central axis of rotation, and the entire fog lamp 40 operates in an oblique rotational direction.

  The operating shaft 66 is formed in an oblique direction that is directed from the outside to the inside as the fog lamp 40 is mounted on the vehicle 1 from above to below. Further, since the rod fixing portion 64 is formed on the outer side of the operation shaft 66, when the rod 63 of the levelizer 62 is contracted, the specific operation direction of the fog lamp 40 is forward. The reflecting surface 55 of the facing reflector 54 operates in a direction of rotation that is directed downward while facing downward. That is, the left fog lamp 41 operates in a direction in which the reflective surface 55 faces downward while facing the left side, and the right fog lamp 42 in a direction in which the reflective surface 55 faces downward and toward the right side. Operates on.

  The length of the fog lamp 40 from the first support portion 60 to the rod fixing portion 64 in the vertical direction is shorter than the length from the operating shaft 34 of the headlamp 10 to the rod fixing portion 32. In other words, the fulcrum pitch K, which is the length from the operating portion of the fog lamp 40 to the support portion 59, is formed shorter than the fulcrum pitch J, which is the length from the operating portion of the headlamp 10 to the support portion 29. Therefore, when the rod 63 of the leveler 62 of the fog lamp 40 is contracted by the same amount as the rod 31 of the leveler 30 of the headlamp 10, the rotation angle at which the fog lamp 40 operates in the rotational direction about the operating shaft 66 is the headlamp 10. Operates at a rotation angle larger than the rotation angle at which the operation shaft 34 operates in the rotation direction.

  FIG. 7 is a diagram illustrating a state in which the headlamp is directed downward. FIG. 8 is a diagram illustrating a state in which the fog lamp faces downward. As described above, the fog lamp 40 operates at a larger rotation angle than the headlamp 10, but the operating shaft 34 of the headlamp 10 is formed in the horizontal direction, and the operating shaft 66 of the fog lamp 40 is inclined. Is formed. Therefore, the vertical rotation angle P of the headlamp 10 is the magnitude of the rotation angle when the headlamp 10 is rotated about the operation shaft 34, but the vertical rotation angle Q of the fog lamp 40 is centered on the operation shaft 66. As a result, the rotation angle becomes smaller than the rotation angle. Thereby, when both the headlamp 10 and the fog lamp 40 are operated in the rotation direction, the vertical rotation angle P and the rotation angle Q are the same, and the headlamp 10 and the fog lamp 40 are downward at the same angle. Change direction. Since the vehicle 1 is tilted so that the front is upward, the headlamp 10 and the fog lamp 40 are turned before the vehicle 1 is tilted. A predetermined direction in front is irradiated in the same manner as the direction in which the light has traveled. Furthermore, since the fog lamp 40 changes its direction in the outward direction while changing its direction downward, the fog lamp 40 changes the irradiation direction downward and at the same time irradiates the outward direction with respect to the traveling direction of the vehicle 1.

  Contrary to the above, when the front of the vehicle 1 is inclined downward, the inclination detection sensor detects the inclination in the same manner as described above, and the vehicle lamp control unit detects the inclination according to the detected inclination. An electrical signal is sent to the leveler 30 of the lamp 10. Contrary to the above, the leveler 30 extends according to the inclination of the rod 31 detected by the inclination detection sensor. When the rod 31 of the leveler 30 is extended, the headlamp 10 is opposite to the above in the direction in which the reflecting surface 25 of the reflector 24 faces upward, and the entire headlamp 10 is in the rotational direction with the operating shaft 34 as the central axis of rotation. Operate. Thereby, the irradiation light which irradiates ahead is irradiated upwards compared with before the operation | movement of the rotation direction of the headlamp 10. FIG.

  When the vehicle 1 is tilted, the same signal as the signal sent from the vehicle lamp control unit to the leveler 62 of the headlamp 10 is also sent to the fog lamp 40. When tilted downward, the vehicle 1 operates in the direction opposite to that when the front of the vehicle 1 tilts upward. Specifically, the leveler 62 of the fog lamp 40 extends by the same amount as the leveler 62 of the headlamp 10. Thus, the fog lamp 40 as a whole is operated in the direction of rotation in the direction facing inward, with the direction of the reflecting surface 55 facing upward, with the operating shaft 66 as the center axis of rotation. That is, the left fog lamp 41 operates in a direction in which the reflecting surface 55 faces upward and toward the right side, and the right fog lamp 42 in a direction toward the left side while the reflecting surface 55 faces upward. Operate.

  Even when the fog lamp 40 and the head lamp 10 are operated in the opposite directions as described above, the vertical rotation angle Q of the fog lamp 40 is the same as the rotation angle P of the head lamp 10 as described above. Become. That is, the headlamp 10 and the fog lamp 40 are turned upward at the same angle. Since the vehicle 1 is tilted so that the front side is downward, the headlamp 10 and the fog lamp 40 change the direction in this manner, so that the vehicle 1 has a predetermined forward direction similar to the direction irradiated before the vehicle 1 tilts. Irradiate the direction. Further, since the fog lamp 40 changes its direction in the inner direction while changing its direction upward, the fog lamp 40 changes the irradiation direction upward and simultaneously irradiates the inner direction with respect to the traveling direction of the vehicle 1. As described above, when the optical axes of the headlamp 10 and the fog lamp 40 are adjusted by the levelizers 30 and 62, the irradiation range of the fog lamp 40 is maintained in the vertical position relative to the irradiation range of the headlamp 10. However, the relative position in the left-right direction of the irradiation range moves.

  9-11 is a figure which shows the irradiation range of a headlamp and a fog lamp. The HH line in the figure indicates a horizontal line in front of the vehicle as viewed from the driver's seat of the vehicle 1, and the VV line similarly indicates a vertical line in front of the vehicle as viewed from the driver's seat of the vehicle 1. When the optical axis of the headlamp 10 is adjusted in the vertical direction as described above, the irradiation range of the headlamp 10 moves in the vertical direction according to the angle of the headlamp 10. Further, when the optical axis of the headlamp 10 is adjusted in this way, the fog lamp 40 operates in an oblique direction, and the irradiation range of the fog lamp 40 is such that the movement distance in the vertical direction is above and below the irradiation range of the head lamp 10. It moves in an oblique direction with the same movement distance as the movement distance in the direction. That is, the irradiation range of the fog lamp 40 moves in the horizontal direction relative to the irradiation range of the headlamp 10 while maintaining the positional relationship in the vertical direction between the irradiation range of the headlamp 10 and the irradiation range of the fog lamp 40. .

  For example, as an example of the irradiation range of the headlamp 10 and the irradiation range of the fog lamp 40, a passing beam irradiation range 110 that is an irradiation range of a headlamp used for a passing beam when the vehicle 1 is not tilted, and a left fog lamp A fog lamp irradiation range 140 that is the irradiation range of 41 is shown in FIG. In the passing beam irradiation range 110, a cut line 111 is formed on the upper portion so as not to give glare to the oncoming vehicle or the like. Further, the fog lamp irradiation range 140 irradiates the inside of the passing beam irradiation range 110, and the upper part thereof is a position that is below the cut line 111 of the passing beam irradiation range 110 by a distance S.

  When the headlamp 10 operates upward as described above and the low beam irradiation range 110 moves upward, the fog lamp irradiation range 140 of the left fog lamp 41 moves to the right while moving upward ( FIG. 10). At this time, since the vertical rotation angle P of the headlamp 10 and the vertical rotation angle Q of the fog lamp 40 operate at the same angle when the optical axis of the headlamp 10 is adjusted, the low beam irradiation range 110 and the fog lamp irradiation range are operated. 140 both move upward while maintaining the spacing S constant. When the headlamp 10 operates downward and the low beam irradiation range 110 moves downward, the left fog lamp 41 moves to the left while moving downward (FIG. 11). Even in this case, the low beam irradiation range 110 and the fog lamp irradiation range 140 are both moved downward while maintaining the interval S constant, as in the case where the low beam irradiation range 110 has moved upward.

  In the above vehicle lamp, the operating shaft 34 of the headlamp 10 is formed in the horizontal direction, and the operating shaft 66 of the fog lamp 40 is formed in the oblique direction. Therefore, the adjustment direction of the optical axis of the headlamp 10 and the fog lamp The adjustment directions of the 40 optical axes can be adjusted in different directions. As a result, even if the fulcrum pitch is different between the headlamp 10 and the fog lamp 40, the light in the predetermined direction of both vehicle lamps can be set by arbitrarily setting the angles of the operating shafts 34 and 66. The adjustment range of the shaft can be set to an arbitrary size.

  That is, as described above, even when the fulcrum pitch K of the fog lamp 40 is shorter than the fulcrum pitch J of the headlamp 10, the angle of the operating shaft 66 of the fog lamp 40 can be set to an arbitrary angle with respect to the operating shaft 34 of the headlamp 10. Even if the operation amount input to the operation unit is the same by setting the oblique direction, the adjustment amount of the optical axis of the fog lamp 40 in the same direction as the adjustment direction of the optical axis of the headlamp 10 is the same size. Can be. Alternatively, when the adjustment amount of the optical axis of the headlamp 10 and the adjustment amount of the optical axis of the fog lamp 40 in the adjustment direction of the optical axis of the headlamp 10 are set to the same size, they are input to the operating unit. The magnitude of the operation amount can be made the same.

  Thereby, the operating means for adjusting the optical axis, that is, the leveler 30 of the headlamp 10 and the leveler 62 of the fog lamp 40 can be made the same. Furthermore, when the optical axes of both the headlamp 10 and the fog lamp 40 are adjusted, the same electrical signal can be input to both levelers 30 and 62. Thus, the adjustment angle of the optical axis in the predetermined direction of the fog lamp 40 and the headlamp 10 having different fulcrum pitches can be matched with the same signal to the plurality of operating means. As a result, the adjustment angle of the optical axis of the fog lamp 40 can be easily adjusted to the adjustment angle of the optical axis of the headlamp 10, and the fulcrums of the fog lamp 40 and the headlamp 10 that can adjust the optical axis in this way. Even when the pitch is different, the parts can be shared and the structure can be simplified. As a result, the manufacturing becomes easy, and the manufacturing cost can be reduced.

  In addition, since the cut line 111 is formed in a predetermined shape above the passing beam irradiation range 110 in the irradiation range of the headlamp 10, when the passing beam irradiation range 110 moves in the left-right direction, it is opposed. It becomes dazzling against cars. However, since such a cut line is not formed in the fog lamp irradiation range 140 and mainly irradiates below the cut line 111 of the passing beam irradiation range 110, the fog lamp irradiation range 140 is in the horizontal direction. Even if it moves to, it does not become glare with respect to an oncoming vehicle etc. like the case where the passing beam irradiation range 110 moves to the left-right direction. Thereby, when the movement amount of the irradiation direction in the predetermined direction of the headlamp 10 and the fog lamp 40 is adjusted, the irradiation direction of the fog lamp 40 is moved in an oblique direction to match the movement amount of the irradiation range of the headlamp 10 in the vertical direction. be able to. As a result, when the movement amount in the vertical direction of the irradiation direction of the fog lamp 40 is matched with the movement amount of the optical axis adjustment in the vertical direction of the irradiation direction of the headlamp 10, both of them are practically used without giving glare to the outside. Optical axis adjustment can be performed.

  In addition, since the optical axis of the fog lamp 40 is adjusted in the same manner as the headlamp 10 according to the inclination of the vehicle 1, even when the vehicle 1 is inclined, it can give glare to external vehicles, pedestrians, and the like. Absent. Thereby, a light source that emits light with a bright light quantity like the discharge bulb 15 can be used as the light source of the fog lamp 40. As a result, external visibility when using the fog lamp 40 is improved, and safety is improved. Further, the irradiation range of the fog lamp 40 using the discharge bulb 15 that emits light with such a bright light amount is overlapped with the irradiation range of the head lamp 10, and the irradiation range of the fog lamp 40 is moved in accordance with the movement of the irradiation range of the head lamp 10. Therefore, the irradiation range of the headlamp 10 can be further brightened. As a result, forward visibility at night and the like is further improved, and safety is improved.

  FIG. 12 is a view showing both the right and left fog lamps of the vehicular lamp according to the second embodiment. This vehicular lamp has substantially the same configuration as the vehicular lamp according to the first embodiment, except that the rod fixing portion of the fog lamp is formed closer to the center of the vehicle than the first support portion and the second support portion. There is a feature. Since other configurations are the same as those of the first embodiment, the description thereof is omitted and the same reference numerals are given. As with the fog lamp 40 of the first embodiment, the fog lamps 80 are provided on the left and right of the front portion of the vehicle 1, and two sets of support portions 94 are provided for each fog lamp 80. In the left fog lamp 81, which is a fog lamp 80 provided on the left side of the vehicle 1, the first support portion 95 is located above the left-right direction center line 72 and to the left side of the up-down direction center line 71. positioned. The second support portion 96 is located below the left-right direction center line 72, located on the left side of the up-down direction center line 71, and further on the left side of the first support portion 95. positioned. Similarly to the fog lamp 40 of the first embodiment, the virtual axis passing through the first support portion 95 and the second support portion 96 also becomes the operation axis 101 in the fog lamp 80 of the second embodiment, and the optical axis of the fog lamp 80 is adjusted. Is adjusted by operating the fog lamp 80 in the rotation direction about the operating shaft 101. Further, the operating shaft 101 of the left fog lamp 81 moves upward as it goes from the right side to the left side because the second support portion 96 is located below the first support portion 95 and on the left side as described above. It is formed so as to incline downward in the downward direction, that is, upward to the right.

  Further, the rod fixing portion 99 formed on the left fog lamp 81 is below the left fog lamp 81, on the right side of the insertion hole 67, that is, below the horizontal center line 72, and in the vertical center line 71. It is provided on the right side. Similarly to the leveler 62 of the fog lamp 40 of the first embodiment, the leveler 62 provided at the rear of the fog lamp 80 is provided at a position where the rod 63 can be engaged with the rod fixing portion 99. The rod 63 is provided below the left fog lamp 81 so as to be located on the right side of the insertion hole 67. Further, the rod fixing portion 99 and the rod are provided so as to be positioned below the second support portion 96.

  The positions of the support portion 94, the rod fixing portion 99, and the leveler 62 of the right fog lamp 82, which is the fog lamp 80 provided on the right side of the vehicle 1, are centered on the vertical center line 71 with respect to the left fog lamp 81. Each is a line-symmetrical position. That is, the first support portion 95 is located above the left-right direction center line 72 and is located to the right side from the up-down direction center line 71. Further, the second support portion 96 is located below the left-right direction center line 72, located on the right side of the up-down direction center line 71, and further on the right side of the first support portion 95. positioned. Further, since the first support portion 95 and the second support portion 96 are arranged as described above, the operating shaft 101 of the right fog lamp 82 is lowered rightward symmetrically with the operating shaft 101 of the left fog lamp 81. It is formed to tilt.

  The rod fixing portion 99 formed on the right fog lamp 82 is located below the right fog lamp 82 on the left side of the insertion hole 67, that is, below the left-right direction center line 72, and in the up-down direction center line. It is provided on the left side of 71. The leveler 62 is provided at a position where the rod 63 can be engaged with the rod fixing portion 99, and the rod 63 of the levelizer 62 is positioned below the right fog lamp 82 and on the left side of the insertion hole 67. Is provided. Further, the rod fixing portion 99 and the rod 63 are provided so as to be positioned below the second support portion 96.

  As described above, the positional relationship between the rod fixing portion 99 of the fog lamp 80 and the first support portion 95 and the second support portion 96 is such that the rod fixing portion 99 is in the first support state when the fog lamp 80 is mounted on the vehicle 1. It is provided so as to be located on the inner side of the portion 95 and the second support portion 96 or on the center side of the vehicle 1. Furthermore, the direction of inclination of the operating shaft 101 is inclined in a direction from the inside to the outside as it goes from the top to the bottom in a state where the fog lamp 80 is mounted on the vehicle 1.

  Further, the fog lamp 80 of the second embodiment is the longest portion of the length from the support portion 94 of the fog lamp 80 to the rod fixing portion 99 in the vertical direction, similarly to the fog lamp 40 of the first embodiment. The length from 1 support part 95 to the rod fixing | fixed part 99 is formed shorter than the up-and-down width of the operating shaft 34 and the rod fixing | fixed part 99 of the said headlamp 10. FIG.

  The vehicular lamp according to the second embodiment is configured as described above, and the operation thereof will be described below. If the front of the vehicle 1 is tilted upward with respect to the road surface when the headlamp 10 and the fog lamp 80 are turned on, the tilt detection sensor detects the tilt, and the head is controlled from the vehicle lamp control unit according to the detected tilt. The rod 31 of the levelizer 30 is contracted by a signal sent to the levelizer 30 of the lamp 10. As a result, the headlamp 10 operates in the rotational direction with the operating shaft 34 as the central axis in the direction in which the reflecting surface 25 of the reflector 24 faces downward, and the irradiation light irradiating the front is in the rotational direction of the headlamp 10. Irradiated downward compared to before operation. Thus, when the vehicle 1 is tilted and the leveler 30 of the headlamp 10 is activated, the same signal as the signal sent from the vehicle lamp control unit to the leveler 30 of the headlamp 10 is also sent to the leveler 62 of the fog lamp 80. . The leveler 62 of the fog lamp 80 that has received this signal from the vehicle lamp control unit operates in the direction in which the rod 63 contracts by the same amount as the leveler 30 of the headlamp 10.

  The operating shaft 101 of the fog lamp 80 is formed in an oblique direction in a direction from the inner side toward the outer side as it goes from the upper side to the lower side when the fog lamp 80 is mounted on the vehicle 1. Further, since the rod fixing portion 99 is formed to be located inward of the operation shaft 101, when the rod 63 of the levelizer 62 is contracted, the specific operation direction of the fog lamp 80 is forward. The reflecting surface 55 of the facing reflector 54 operates in a direction of rotation that is directed inward while facing downward. That is, the left fog lamp 81 operates in a direction in which the reflective surface 55 faces downward and toward the right side, and the right fog lamp 82 in a direction in which the reflective surface 55 faces downward and toward the left side. Operates on. Further, when the direction of the fog lamp 80 is changed in this way, as with the fog lamp 40 of the first embodiment, the rotation angle at which the fog lamp 80 operates in the rotational direction about the operating shaft 101 is the headlamp 10 operating shaft. It operates at a rotation angle larger than the rotation angle that operates in the rotation direction with 34 as the central axis.

  Further, since the operating shaft 101 of the fog lamp 80 and the operating shaft 34 of the headlamp 10 are formed at different angles, when both operate in the rotational direction with the operating shafts 34 and 101 as the central axes as described above, Are the same in the vertical rotation angle. That is, the head lamp 10 and the fog lamp 80 are turned downward at the same angle as in FIGS. 7 and 8 of the first embodiment. Since the vehicle 1 is tilted so that the front is upward, the headlamp 10 and the fog lamp 80 change the direction in this manner, so that the vehicle 1 has a predetermined front as in the direction irradiated before the vehicle 1 tilts. Irradiate the direction. Further, since the fog lamp 80 changes its direction in the inner direction while changing its direction downward, the fog lamp 80 irradiates the inner direction with respect to the traveling direction of the vehicle 1 at the same time as changing the irradiation direction downward.

  Contrary to the above, when the front of the vehicle 1 is inclined downward, the inclination detection sensor detects the inclination in the same manner as described above, and the headlamp 10 is detected from the vehicle lamp control unit according to the detected inclination. The rod 31 of the levelizer 30 is extended by a signal sent to the levelizer 30. As a result, the headlamp 10 operates in the rotational direction with the operating shaft 34 as the central axis in the direction in which the reflecting surface 25 of the reflector 24 faces upward, and the irradiation light irradiating the front is in the rotational direction of the headlamp 10. Irradiated upward compared to before operation.

  When the vehicle 1 is tilted, the same signal as the signal sent from the vehicle lamp control unit to the leveler 30 of the headlamp 10 is also sent to the fog lamp 80. When tilted downward, the vehicle 1 operates in the direction opposite to that when the front of the vehicle 1 tilts upward. Specifically, the leveler 62 of the fog lamp 80 extends by the same amount as the leveler 30 of the headlamp 10. As a result, the fog lamp 80 as a whole is operated in the direction of rotation in the direction facing the outside while the direction facing the reflection surface 55 is directed upward, with the operation shaft 101 as the center axis of rotation. That is, the left fog lamp 81 operates in a direction in which the reflective surface 55 faces upward while facing the left side, and the right fog lamp 82 in a direction in which the reflective surface 55 faces upward while facing the right side. Operate.

  Even when the fog lamp 80 and the head lamp 10 are operated in the opposite directions as described above, the rotational angle in the vertical direction is the same as that of the head lamp 10 as described above, and the head lamp 10 and the fog lamp 80 are Turn upwards at the same angle. Since the vehicle 1 is tilted so that the front side is downward, the headlamp 10 and the fog lamp 80 change the direction in this manner, so that the vehicle 1 has a predetermined forward direction similar to the direction irradiated before the vehicle 1 is tilted. Irradiate the direction.

  When the vehicle lamp is tilted so that the front of the vehicle 1 is upward with respect to the road surface formation direction, for example, when the vehicle 1 is accelerated, the fog lamp 80 is directed inward while the reflecting surface 55 is directed downward. Operate in the direction. Thereby, at the time of acceleration, the irradiation light from the fog lamp 80 is irradiated toward the center in front of the vehicle 1. When the vehicle 1 is accelerated, it is necessary to improve the visibility in the distance from the front, that is, near the center, but the fog lamp 80 can irradiate the vicinity of the front center when the vehicle 1 is accelerated. As a result, visibility during acceleration can be improved, and safety can be improved.

  Further, when the vehicle 1 is inclined so that the front of the vehicle 1 is downward with respect to the road surface formation direction, for example, when the vehicle 1 is decelerated, the fog lamp 80 operates in a direction toward the outside while the reflecting surface 55 is directed upward. Thereby, at the time of deceleration, the irradiation light from the fog lamp 80 is irradiated toward the outside in front of the vehicle 1. When the vehicle 1 decelerates, it is necessary to improve the visibility of the entire vicinity in the front. However, when the vehicle 1 decelerates, the fog lamp 80 can irradiate the entire vicinity by irradiating the front outer direction. As a result, visibility during deceleration can be improved, and safety can be improved.

  In addition, as described above, the optical axis of the fog lamp 80 is adjusted according to the inclination of the vehicle 1, and the irradiation light is emitted in a direction to be emphasized when the outside is visually recognized when the vehicle 1 is accelerated and decelerated. Thus, in many cases when the vehicle 1 is driven, a necessary part can be irradiated. That is, the irradiation direction of the fog lamp 80 can be matched with the driver's field of view. As a result, the safety during driving of the vehicle 1 when the outside is dark, such as at night, is improved, and the driver can be exposed to the outside during driving at night by matching the direction of irradiation of the fog lamp 80 with the driver's field of view. Can be reduced.

  Although the above-described vehicular lamp has been described for adjusting the optical axis according to the inclination of the vehicle 1, the vehicle 1 is equipped with a vehicle speed sensor (not shown) and the optical axis is adjusted by the vehicle speed. It may be used for a vehicular lamp. For example, in the vehicular lamp of the first embodiment, the optical axes of the headlamp 10 and the fog lamp 40 are directed upward, while the optical axis of the fog lamp 40 is directed inward. As a result, the distant visibility at the time of high speed traveling is further improved and the safety is improved. Further, in the vehicular lamp of the first embodiment, the optical axes of the headlamp 10 and the fog lamp 40 are directed downward and the optical axis of the fog lamp 40 is directed outward. However, the vehicle lamp travels at a low speed, that is, on a narrow alley. When the optical axis is changed in this way, the visibility in a wide range near the front of the vehicle 1 is improved, so that the safety is further improved.

  Further, the arrangement of the head lamp and fog lamp support section and the operation section may be other than the above. The head lamp 10 has the operating shaft 34 formed in the horizontal direction, and the fog lamps 40, 80 are provided with support portions 29, 59, 94 so that the operating shafts 66, 101 are formed in the oblique direction. If the rod fixing portions 32, 64, 99 are arranged at positions where the vertical rotation angles of the headlamp 10 and the fog lamps 40, 80 are the same when the amount is input to the rod fixing portions 32, 64, 99. The position may be any position. Further, the operating shafts 34 and 66 are formed as virtual axes that pass through the two support portions, but may be axes that are actually formed instead of virtual axes. Moreover, although the discharge bulb 15 has been described as the light source of the headlamp 10 and the fog lamp 40, a light source other than the discharge bulb 15 such as a halogen bulb or an incandescent bulb may be used as the light source.

  As described above, the vehicular lamp according to the present invention is useful when the auxiliary headlamp is provided with the optical axis adjusting mechanism, and is particularly suitable when the components for adjusting the optical axis are used in common.
