The vehicle lamp in this embodiment will be described with reference to headlamps such as headlamps, fog lamps, and front combination lamps provided on the left and right of the front portion of the vehicle.

  In the figure, reference numeral 1 denotes a vehicular lamp in this embodiment. In this example, for example, headlamps, fog lamps, front combination lamps and the like mounted on the left and right of the front portion of the vehicle, that is, lamps It is the main body. The lamp body 1 includes a rear lamp housing 2 and a front lamp lens 3 that define a lamp chamber (not shown), a light source (not shown) disposed in the lamp chamber, and light from the light source. A reflector (not shown) that reflects and radiates the lamp lens 3 to the outside is used.

  The lamp body 1 of this embodiment is securely attached to the vehicle body 4 by an attachment structure including first attachment means and second attachment means. The vehicle body 4 is formed with a space for housing the lamp body 1. That is, the space is formed by being surrounded by a vehicle body panel of the vehicle body 4.

  The first mounting means is for rotatably mounting the lower part of the lamp body 1 to the vehicle body 4. That is, the first mounting means is provided at two locations on a straight line OO on the left and right sides of the front side (location close to the lamp lens 3) at the lower portion of the lamp body 1, for example, the lower portion of the lamp housing 2. It is composed of two pins 5 and 6 and first mounting portions 9 and 10 having through holes 7 and recesses 8 provided on the vehicle body 4 on a straight line OO. The two pins 5 and 6 are rotatably attached to the through hole 7 and the recess 8 respectively. The through-hole 7 is formed by integrally forming a short cylindrical convex portion on the first mounting portion 9, while the concave portion 8 is formed by bending a part of the first mounting portion 10 into a semicircular shape. . The straight line OO is a rotation center line of the first attachment means. A rotation center line OO of the first mounting means is disposed obliquely below and forward of the lamp body 1 with respect to the second mounting means.

  The second attachment means attaches the upper part of the lamp body 1 to the vehicle body 4 so as to be detachable, and applies an impact force greater than a predetermined value obliquely upward to the lamp lens 3 on the front surface of the lamp body 1 (FIG. 2). It falls off when applied (see arrow A in the middle). The second mounting means includes two second mounting portions 11 provided on the upper part of the lamp body 1, for example, on the upper side of the lamp housing 2 and on both the left and right sides of the rear side, and one end of the vehicle body 4. The other end is attached to the second mounting portion 11 so that the lamp lens 3 on the front surface of the lamp body 1 can be detached when an impact force greater than a predetermined value is applied obliquely from above. Bracket 12 is provided.

  The second mounting portion 11 is provided integrally with the lamp housing 2 with L-shaped mounting plates facing each other when viewed from the front. A long hole 13 is provided in the left-right direction substantially at the center of the second mounting portion 11. The bracket 12 has a U-shape when viewed from the side. Bolt holes 14 are provided in the upper plate of the bracket 12. The lower plate of the bracket 12 is provided with a thick portion 15, a thin portion 16, and a hook portion 17. The hook part 17 is detachably attached to the long hole 13.

Hereinafter, the operation of the vehicle lamp and the mounting structure of the vehicle lamp in this embodiment will be described. First, how to attach the lamp body 1 to the vehicle body 4 by the first attachment means and the second attachment means will be described.

  That is, the lamp body 1 is manufactured from the lamp housing 2, the lamp lens 3, the light source, the reflector, and the like that are integrally provided with the pins 5 and 6 and the second mounting portion 11, and the bracket 12 is manufactured. The lamp body 1 and the bracket 12 are assembled. That is, the thick portion 16 of the bracket 12 is inserted between the upper portion of the lamp housing 2 and the second mounting portion 11, and the hook portion 17 of the bracket 12 is inserted into the long hole 13 of the second mounting portion 11.

  Then, in the car maker, the lamp body 1 assembled with the bracket 12 is attached to the vehicle body 4 by the first attachment means and the second attachment means. That is, the pin 5 of the lamp body 1 is rotatably attached to the through hole 7 of the first attachment portion 9 of the vehicle body 4. Further, the pin 6 of the lamp body 1 is rotatably attached to the recess 8 of the first attachment portion 10 of the vehicle body 4. Further, the bracket 12 of the lamp body 1 is attached to the vehicle body 4 with bolts and nuts 18. Thereby, the lamp body 1 is accommodated in the space of the vehicle body 4 and attached to the vehicle body 4 by the first attachment means and the second attachment means. Since the lamp body 1 is securely attached to the vehicle body 4 by the first attachment means and the second attachment means, the lamp body 1 is not shaken by vibrations or the like when the vehicle travels. Light control is obtained.

  Next, removal of the lamp body 1 attached to the vehicle body 4 by the first attachment means and the second attachment means will be described.

  For example, when the lamp body 1 mounted on the left and right of the front part of the vehicle hits a person, the lamp body 1 is normally positioned at a lower position than the person. An impact force (see arrow A in FIG. 2) is applied to the lamp lens 3 on the front surface of 1 obliquely from above. Then, the lamp body 1 rotates in the direction of arrow B (counterclockwise) in FIG. 2 around the rotation center line OO of the first mounting means, and accordingly, the second mounting portion 11 is also moved. Similarly, it rotates in the direction of arrow B (counterclockwise) in FIG. Thereby, the inner surface of the long hole 13 of the second mounting portion 11 pushes the hook portion 17 of the bracket 12 in the direction of arrow B, so that the thin portion 16 of the bracket 12 is deformed and the hook portion 17 is in the direction of arrow C in FIG. Move to. The movement of the hook portion 17 has friction or resistance between the inner surface of the long hole 13 of the second attachment portion 11.

  When the impact force applied to the lamp body 1 and a person is equal to or greater than a predetermined value, the hook portion 17 is removed from the long hole 13, and the lamp body 1 moves backward with respect to the vehicle body 4, that is, rotates rearward. For this reason, an impact force is relieved and the impact force to a person is reduced.

  If the bracket 12 removed from the second attachment portion 11 is not damaged, the lamp body 1 can be attached to the vehicle body 4 again by reusing the bracket 12. If the bracket 12 is damaged, the lamp body 1 can be reattached to the vehicle body 4 by replacing the damaged bracket 12 with a new bracket 12.

  Hereinafter, the effects of the vehicular lamp and the mounting structure of the vehicular lamp in this embodiment will be described. In this embodiment, the vehicular lamp and the mounting structure of the vehicular lamp are such that when the front surface of the lamp body 1 is subjected to an impact force greater than or equal to a predetermined value obliquely from above, the second mounting means falls off, thereby causing an obstacle collision. Is intended to mitigate impact. As described above, in the vehicle lamp and the vehicle lamp mounting structure in this embodiment, since the second mounting means is simply removed, the lamp body 1 can be reused, and there is no need to replace the lamp body 1. The cost is reduced accordingly. In the vehicle lamp and the vehicle lamp mounting structure in this embodiment, the lamp body 1 is securely mounted to the vehicle body by the first mounting means and the second mounting means. As a result, predetermined light distribution control can be obtained.

  In particular, in the vehicle lamp and the vehicle lamp mounting structure in this embodiment, the first mounting means is composed of the two pins 5, 6 and the through holes 7 and the recesses 8, and the second mounting means. Is composed of a second mounting portion 11 and a bracket 12. For this reason, the mounting structure of the vehicular lamp and the vehicular lamp in this embodiment can securely mount the lamp body 1 to the vehicle body 4 by the first mounting means and the second mounting means having a simple structure. In addition, in this example, two bolts and nuts 18 for attaching the second attachment portion 11 and the bracket 12 are sufficient, and accordingly, the number of parts is reduced and the number of assembly steps is reduced, and the manufacturing cost is reduced. Can do.

  Further, in the vehicle lamp and the vehicle lamp mounting structure in this embodiment, the rotation center line OO of the first mounting means is disposed obliquely in front of the lamp body 1 below the second mounting means. For this reason, the vehicle lamp and the mounting structure of the vehicle lamp in this embodiment have the lamp body 1 when the lamp body 1 of the host vehicle hits a place of almost the same height as another vehicle or other obstacle. Since a substantially horizontal impact force (see arrow III in FIG. 2) is applied to the lamp lens 3 in front of the lamp lens, the lamp is compared with a case where an impact force (arrow A in FIG. 2) is applied obliquely from above. The main body 1 is difficult to rotate and does not easily fall off the vehicle body 4.

  In the embodiment described above, headlamps such as headlamps, fog lamps, and front combination lamps provided on the left and right of the front portion of the vehicle will be described. However, in the present invention, other vehicle lamps, rear combination lamps, and the like may be used.

  In the above-described embodiment, the lamp body 1 is provided with the two pins 5 and 6 of the first attachment means, and the vehicle body 4 is provided with the through holes 7 and the recesses 8 of the first attachment means. However, in the present invention, the lamp body 1 may be provided with the through holes 7 and the recesses 8 and the vehicle body 4 may be provided with two pins, or the lamp body 1 may have one pin 5 or 6 and through-holes 7 or recesses 8 may be provided, and one pin 6 or 5 and recesses 8 or through-holes 7 may be provided on the vehicle body 4.
