And high beam light distribution pattern). The projection lens 15 is supported by the lens holder 16 and is positioned with respect to the light source 11 and the reflector member 13. The lens holder 16 is paired in the width direction (only the front side is shown), and has a guide hole 16a and a screw hole 16b arranged vertically, and a screw hole 16c above the guide hole 16a.

The shade unit 14 switches the light distribution of the projected light projected by the projection lens 15 between a low beam light distribution pattern and a high beam light distribution pattern. The shade unit 14 includes a bracket plate 31, a shade 32 that is displaced for switching, a solenoid 33 as a drive unit that operates to displace it, and a link mechanism 34 that transmits the operation to the shade 32. To be equipped. The bracket plate 31 is formed by appropriately bending a plate-shaped member, bearing portions 35 are provided at the upper edges of both left and right ends, and a connecting opening 36 is provided on the left side of the center (the front side when viewed from the front in FIG. 1). .. Each of the bearing portions 35 is formed by appropriately cutting out and bending the upper edge portion of the bracket plate 31, and rotatably supports the rotating shaft 37. Further, the bracket plate 31 is provided with a guide hole 31a and a screw hole 31b in pairs on the left and right ends.

The shade 32 blocks a part of the light emitted from the light source 11 to form a cut-off line of the light distribution pattern. The shade 32 is rotatably provided on the bracket plate 31 about the rotation shaft 37. As shown in FIGS. 4 and 5, in the first embodiment, the shade 32 is configured by attaching a thin plate-shaped first shade portion 42 and a second shade portion 43 to a plate-shaped rotating base portion 41.

A pair of bearing pieces 44 are provided on both sides of the rotating base 41, and a rotating shaft 37 (see FIG. 6 and the like) is inserted into the shaft holes 44a formed in each of the bearing pieces 44. One end of the rotating shaft 37 is attached to a receiving portion of the bracket plate 31, and the other end is passed through a small hole 41a (see FIG. 4 and the like) of the rotating base 41 of the shade 32. 7) is provided. The torsion coil spring 45 applies a rotational force in the direction in which the first shade portion 42 and the second shade portion 43 approach the projection lens 15 to the rotary base portion 41 that is rotatable with respect to the bracket plate 31.

Further, the rotation base 41 has a pair of a first positioning piece 46, a second positioning piece 47, a transmission piece 48, and an opening 49. The first positioning piece 46 is provided below each bearing piece 44 in pairs on the left and right. The second positioning piece 47 is provided above the bearing piece 44 on one side (front side when viewed from the front in FIG. 4). The transmission piece 48 is formed by bending a portion of the rotation base 41 in which the center in the width direction is cut out in a U shape. The opening 49 is formed at the position where the transmission piece 48 before being bent was present. As a result, the rotating base 41 can inexpensively provide the transmission piece 48 while preventing the weight from increasing. The transmission piece 48 may be formed by bending another notched side, and is not limited to the configuration of the first embodiment. The transmission piece 48 has a transmission hole 48a and is located closer to the projection lens 15 than the shaft hole 44a of both bearing pieces 44, as shown in FIG. The transmission piece 48 is provided at the center of the rotation base 41 (shade 32) in the width direction, and efficiently transmits the operation of the solenoid 33 via the link mechanism 34 (the screw coil spring 54 described later) to the rotation base 41. The center in the width direction includes the vicinity of the center within a range that enables efficient transmission, and may not be the center in a strict sense. When the transmission piece 48 is displaced downward, the rotating base 41 is raised (approaching in the vertical direction) in a rotating posture (see the solid line), and when displaced upward, the rotating base 41 is laid down (approaching a horizontal state). (Refer to the broken line). When the rotation base 41 is raised, the rotation shaft 37 passing through both shaft holes 44a is opposed to the opening 49 formed by the transmission piece 48 in the optical axis direction.

The first shade portion 42 is attached to the upper portion of the rotation base portion 41 as shown in FIGS. 4 and 5. The second shade portion 43 is attached to the first shade portion 42 in parallel with the first shade portion 42 at a predetermined interval. The first shade portion 42 and the second shade portion 43 have a shape in which two horizontal edges having different heights are joined by an inclined edge so that their upper edges form a cut-off line. In the first embodiment, the first shade portion 42 has a flat thin plate shape, and the second shade portion 43 has a predetermined shape between the first shade portion 42 and the first shade portion 42 to be attached by appropriately bending the flat thin plate member. There is an interval. In Example 1, the first shade portion 42 and the second shade portion 43 are formed of stainless steel to obtain good wear resistance and corrosion resistance, and have a smooth surface and high reflectance. In the shade 32, when the rotation base 41 is in the rotational posture, the upper edges (each edge) of the first shade portion 42 and the second shade portion 43 are located at or near the focal positions of the reflector member 13 and the projection lens 15. Arranged like this.

As shown in FIGS. 4 and 5, the shade 32 has a second shading piece 28 formed so as to project toward the light source 11 above the opening 49. In the first embodiment, the second shading piece 28 is formed by bending the lower end of the first shade portion 42 attached to the rotation base 41 in the shade 32. The second light-shielding piece 28 has a width dimension larger than the width dimension of the opening 49 in the width direction, and the rotation shaft 37 (center position thereof) adjacent to the opening 49 in the optical axis direction when the rotation base 41 is raised. It is a length dimension that extends to a position that covers the upper part of the (see FIG. 6). The second light-shielding piece 28 is located on a path (second path P2 (see FIG. 6) described later) from the upper part of the reflector member 13 to the projection lens 15 through the rotation shaft 37 and the opening 49.

As shown in FIG. 1 and the like, the solenoid 33 has a coil 51, a yoke 52 incorporating the coil 51, and a plunger 53 advancing and retreating from the coil 51, and the yoke 52 is the front surface of the bracket plate 31 (projection lens 15 side). It is configured by being crimped and fixed to the surface). A transmission groove 53a is formed at the tip of the plunger 53, and the plunger 53 is moved forward and backward by energizing or de-energizing the coil 51.

As shown in FIG. 7, the link mechanism 34 has a screw coil spring 54 provided on the rear surface of the bracket plate 31. One end 54a is fitted into the transmission groove 53a of the plunger 53 of the solenoid 33 through the connecting opening 36 of the bracket plate 31, and the other end 54b is fitted into the transmission hole 48a of the transmission piece 48 of the shade 32 (see FIG. 6 and the like). ). The spring constant of the torsion coil spring 54 is set to be larger than the spring constant of the torsion coil spring 45 that applies a rotational force to the shade 32.

In the shade unit 14, guide protrusions 25a of both fixed surface portions 25 of the heat sink member 12 are passed through both guide holes 31a of the bracket plate 31, and the bracket plate 31 is addressed to the heat sink member 12. Both guide protrusions 25a are passed through the corresponding guide holes 16a of the lens holder 16 that supports the projection lens 15. Then, the screw member that has passed through each screw hole 16b of the lens holder 16 and each screw hole 31b of the bracket plate 31 is screwed into the screw hole 25b of each fixed surface portion 25 of the heat sink member 12, and the screw of the lens holder 16 is screwed. The screw member passed through the hole 16c is screwed into each screw hole 26a of the heat sink member 12. As a result, the vehicle lamp 10 is assembled in a state in which the positional relationship between the projection lens 15, the shade unit 14, the reflector member 13, and the light source 11 is determined.

As shown in FIG. 1, the cooling fan unit 17 is configured by rotatably providing a cooling fan 56 connected to a motor in a rectangular parallelepiped frame 55, and is attached below the heat radiation fin 23 of the heat sink member 12. .. When the light source 11 emits light, the cooling fan unit 17 drives the motor to rotate the cooling fan 56 and cools the heat radiation fins 23 of the heat sink member 12, thereby preventing problems due to heat generated by the light source 11. ..

Next, the operation of switching the light distribution pattern in the vehicle lamp 10 will be described. In the vehicle lamp 10, when the coil 51 of the solenoid 33 is de-energized, the shade 32 is generated by the rotational force from the torsion coil spring 45 as shown by the solid line in FIG. 6, and both first positioning pieces 46 are bracket plates 31. It hits. Then, the shade 32 is in a rotational posture in which the first shade portion 42 and the second shade portion 43 block a part of the light reaching the projection lens 15, that is, the low beam position. At this time, the transmission piece 48 of the rotation base 41 is displaced downward, and the plunger 53 of the solenoid 33 is advanced via the link mechanism 34 (see FIG. 7).

When the coil 51 of the solenoid 33 is energized, the plunger 53 of the vehicle lighting tool 10 is retracted against the rotational force of the torsion coil spring 45 (see arrow A1 in FIG. 7), and is fixed to the transmission groove 53a at the tip thereof. When one end 54a is displaced, the torsion coil spring 54 of the link mechanism 34 rotates clockwise (see arrow A2 in FIG. 7). Then, as shown by the chain line in FIG. 6, the shade 32 is laid down by pushing up the transmission piece 48 to which the other end 54b of the screw coil spring 54 is fixed, and the second positioning piece 47 hits the bracket plate 31. Then, the shade 32 is in a rotational posture in which the first shade portion 42 and the second shade portion 43 do not block the light reaching the projection lens 15, that is, the high beam position.

The vehicle lighting fixture 10 reflects the light emitted from the light source 11 to which electric power is supplied forward by the reflector member 13 and projects it forward by the projection lens 15 (see FIG. 2). Then, when the shade 32 is set to the high beam position shown by the chain line in FIG. 6 by the shade unit 14, the vehicle lamp 10 forms a high beam light distribution pattern with the projected light projected forward. Further, when the shade 32 is set to the low beam position shown by the solid line in FIG. 6 by the shade unit 14, the vehicle lamp 10 forms a low beam light distribution pattern having a cut-off line with the projected light projected forward. At this time, since the vehicle lamp 10 forms a cut-off line with the first shade portion 42 and the second shade portion 43 arranged side by side at a predetermined interval, it is possible to suppress the generation of color on the cut-off line. It is possible to blur the vicinity of the cut-off line.

Here, since the vehicle lamp 10 is provided with an opening 49 in the center of the shade 32 that blocks a part of the light, a part of the light reflected by the reflector member 13 when the low beam light distribution pattern is used. May be projected forward from the projection lens 15 through the opening 49. Such light illuminates an unplanned position brightly, such as illuminating a position different from the planned low beam light distribution pattern or illuminating a specific position in the low beam light distribution pattern with unintended brightness. There is a risk. In particular, since the opening 49 is provided for forming a transmission piece 48 that transmits the operation of the solenoid 33 to the shade 32, the opening 49 is provided in the center of the shade 32 in order to stabilize the operation of the shade 32. Therefore, the light traveling through the opening 49 to the projection lens 15 may dazzle oncoming vehicles and other pedestrians.

Then, the applicant confirmed two paths through which such light passes (P1, P2 (see FIGS. 2 and 6)). As shown in FIG. 2, the first path P1 is emitted from the light source 11, reflected by the reflector member 13, and then reflected by the second shade portion 43 (rear surface) of the shade 32, near the root of the reflector member 13. After being reflected by (a portion near the heat sink member 12), it advances to the projection lens 15 through the opening 49. Further, after the second path P2 is reflected by the upper part of the reflector member 13, as shown in FIG. 6, the second path P2 faces between the first shade portion 42 and the second shade portion 43 of the shade 32, and the first shade portion After being reflected by 42 (rear surface), it is reflected by the rotation axis 37 and travels through the opening 49 to the projection lens 15. The second path P2 reaches the front side (projection lens 15) of the upper part on the peripheral surface of the rotating shaft 37, passes through the opening 49, and heads toward the projection lens 15. That is, in both paths (P1, P2), unintended light is emitted from the rear surface of the shade 32 (the first shade portion 42 or the second shade portion 43) that blocks a part of the light, so that unintended light is emitted from the opening 49. It goes through the projection lens 15.

On the other hand, the vehicle lamp 10 of the present invention is provided with light-shielding pieces (first light-shielding piece 27 and second light-shielding piece 28) in order to block light traveling forward from the projection lens 15 through the opening 49. There is. That is, the first light-shielding piece 27 is formed by partially projecting the end portion of the heat sink member 12 on the shade 32 side, and is positioned on the first path P1. Therefore, the light passing through the first path P1 is blocked by the first shading piece 27 and does not reach the opening 49, and is prevented from being projected forward from the projection lens 15. Further, the second shading piece 28 is formed by bending the lower end of the first shade portion 42 in the shade 32, and is positioned on the second path P2 by projecting so as to cover the upper part of the rotation shaft 37. Therefore, the light passing through the second path P2 is blocked by the second shading piece 28, is reflected by the rotating shaft 37, does not reach the opening 49, and is prevented from being projected forward from the projection lens 15. To.

The vehicle lamp 10 of the embodiment of the vehicle lamp according to the present invention can obtain the following effects.

By providing light-shielding pieces (first light-shielding piece 27 and second light-shielding piece 28), the vehicle lamp 10 allows light that can travel forward from the projection lens 15 through the opening 49 to reach the opening 49. Can be blocked by. As a result, the vehicle lamp 10 can suppress the projection of unintended light forward, and can suppress dazzling oncoming vehicles and other passersby.

Further, since the vehicle lamp 10 forms the first light-shielding piece 27 by partially projecting the heat sink member 12 which is the installation base portion on which the light source 11 is provided, the first light source is only required by the initial investment of preparing the corresponding mold. A light-shielding piece 27 can be provided. Therefore, the vehicle lamp 10 can prevent an increase in cost and the weight of the shade 32, as compared with providing the shade 32 with a light-shielding piece which is a member different from the shade 32 so as to close the opening 49, for example. Can be prevented from increasing, and the influence on the operation of the shade 32 can be prevented.

Further, since the vehicle lamp 10 forms the second light-shielding piece 28 by bending the lower end of the first shade portion 42 constituting the shade 32, it is only necessary to change a part of the manufacturing process of the first shade portion 42. 2 The shading piece 28 can be provided. Therefore, as compared with providing the shade 32 with a light-shielding piece which is a member different from the shade 32 so as to close the opening 49, the vehicle lamp 10 can suppress an increase in cost and the weight of the shade 32. Can be suppressed, and the influence on the operation of the shade 32 can be minimized.

Since the vehicle lamp 10 is provided with the first shading piece 27 at the end of the heat sink member 12 on the shade 32 side, it is possible to block the light that can reach the opening 49 immediately before reaching the opening 49, and the first The light-shielding piece 27 can be positioned near the focal position of the reflector member 13 and the projection lens 15. Therefore, the vehicle lamp 10 can block the light that can reach the opening 49 through the first path P1 even if the first light-shielding piece 27 has a small configuration. Further, since the vehicle lamp 10 is formed by extending the first light-shielding piece 27 in the width direction, even light reflected at various positions in the width direction near the root of the reflector member 13 can be blocked. ..

Since the vehicle lamp 10 forms the second light-shielding piece 28 by bending the lower end of the first shade portion 42, it is possible to block the light that can reach the opening 49 immediately before reaching the opening and the second light-shielding piece 28. The shading piece 28 can be positioned near the focal position of the reflector member 13 and the projection lens 15. Therefore, the vehicle lamp 10 can block the light reflected by the rotating shaft 37 so as to pass through the second path P2 and reach the opening 49 even if the second light-shielding piece 28 has a small configuration. Further, in the vehicle lamp 10, since the second light-shielding piece 28 has a width dimension larger than the width dimension of the opening 49, the opening of the light reflected at various positions in the width direction on the rotating shaft 37. The light that can reach 49 can be reliably blocked. Further, since the vehicle lamp 10 has a length dimension that extends the second light-shielding piece 28 to a position that covers the upper part of the rotating shaft 37 (the center position thereof) in the optical axis direction, the projection lens 15 side on the surface of the rotating shaft 37 The light that can reach the (front side) can be reliably blocked. In addition, since the lower end of the first shade portion 42 of the vehicle lamp 10 is bent to form the second light-shielding piece 28, the second light-shielding piece 28 as a protrusion can be present on the flat thin plate-shaped member. , It is possible to suppress sticking between the first shade portions 42 in the cleaning process during manufacturing. In particular, in the vehicle lamp 10, since the second light-shielding piece 28 has a width dimension larger than the width dimension of the opening 49, the second light-shielding piece 28 easily interferes with the adjacent first shade portion 42 to suppress sticking. The effect of can be improved.

Therefore, in the vehicle lamp 10 of the first embodiment as the vehicle lamp according to the present invention, it is possible to suppress unintended light from being emitted through the opening 49 of the shade 32, and it is possible to suppress bright illumination of an unplanned position. it can.
