Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle lamp mounting structure for mounting a vehicle lamp such as a headlight to a lamp mounting portion on an outer surface of a vehicle body.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 5, by fitting a fitting pin 5 projecting on an outer surface of a housing 4 of a vehicle lamp 3 to a grommet 2 provided on a lamp mounting portion on the outer surface of a vehicle body 1, A mounting structure for an automotive lamp, in which an automotive lamp 3 is attached to a lamp mounting portion on the outer surface of 1, is known.

A base end portion 7 of the fitting pin 5 is fitted and fixed in a fitting hole 8 of a protruding wall portion 6 integrally formed with the housing 4 of the vehicle lamp 3.

[0004]

[Problems to be solved by the device]

 In such a conventional vehicle lamp mounting structure, when an external force is applied to the lamp mounting portion of the vehicle body 1 due to a collision or the like, distortion occurs between the vehicle body 1 and the vehicle lamp 3. Depending on the case, the position of the hole 9 into which the grommet 2 of the vehicle body 1 is fitted is often displaced by 10 to 15 mm or more. Therefore, as a result of the external force being transmitted to the housing 4 of the automotive lamp 3 through the grommet 2, the fitting pin 5 and the projecting wall portion 6 in this order, the housing 4 is damaged and rainwater and the like inside the housing 4. There was a problem in that the entire vehicle lighting device 3 had to be replaced depending on the degree of damage or penetration.

The present invention has been made in view of the above circumstances, and even if an external force is applied to a lamp mounting portion of a vehicle body due to a collision or the like, the external force is prevented from being transmitted to a housing of a vehicle lamp, and the housing is damaged. The purpose is to provide a mounting structure for an automobile lamp that prevents the above.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention relates to a vehicle body by fitting a fitting pin projecting on a housing outer surface of a vehicle lamp to a grommet provided on a lamp mounting portion on the outer surface of the vehicle body. In the mounting structure of an automotive lamp in which the automotive lamp is mounted on an outer lamp mounting portion, the fitting pin is externally applied to a mounting base that is detachably mounted on the outer surface of the housing of the automotive lamp. The present invention is characterized in that the protrusion is provided via a breakage portion that breaks at this time and blocks transmission of the external force to the housing.

[0007]

[Action]

 When an external force is applied to the lamp mounting part of the vehicle body due to a collision or the like, the external force is transmitted to the breakage part through the grommet and the fitting pin in order, and the breakage part breaks, so that the external force is applied to the housing of the automotive lamp. Is blocked and damage to the housing is prevented.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a plan view of a vehicle lighting device to which the present invention is applied, and FIG. 2 is a sectional view taken along the line AA of FIG. It has a housing 11, a reflector 12, and a lens 13. One side portion (right side portion in FIG. 1) of the automotive lamp 10 is attached to the lamp attaching portion of the vehicle body 14 by the attaching structure of the present invention.

That is, a pair of fitting pins 15 are provided on one side surface of the housing 11 at predetermined intervals in the vertical direction. The fitting pin 15 includes a flange portion 15a at a substantially intermediate portion in the axial direction, a tapered pin body portion 15b on one end side of the flange portion 15a, and a large-diameter base end portion on the other end side of the flange portion 15a. 15c. As shown in FIG. 3, this base end portion 15c is fitted and fixed in a fitting hole 18 of a mounting member 17 having a cylindrical shape of a short shaft which is integrally provided in the central portion of the mounting base 16. An annular groove (broken portion) 19 is provided on the outer peripheral surface of the base end portion of the mounting member 17. When an external force is applied to the mounting member 17 through the fitting pin 15, the annular groove 19 is broken and the mounting member 17 is separated from the mounting base 16 as shown in FIG. The mounting pedestal 16 is detachably mounted on one side surface of the housing 11 with a screw 20. Then, by fitting the head portion 15b of the fitting pin 15 into the grommet 22 mounted in the mounting hole 21 of the vehicle body 14, one side surface of the housing 11 is attached to the vehicle body 14.

A pair of mounting brackets 23 are provided on the other side surface of the housing 11 so as to be vertically spaced at a predetermined interval. A screw insertion hole 24, which is an elongated hole, is formed in the mounting bracket 23. Then, the other side surface of the housing 11 is attached to the vehicle body 14 by attaching the mounting bracket 23 to the vehicle body 14 with screws (not shown).

In the above configuration, when an external force is applied to the lamp mounting portion of the vehicle body 14 due to a collision or the like, the external force is transmitted to the mounting member 17 through the grommet 22 and the fitting pin 15 in order, and the annular groove 19 is Since the mounting member 17 is broken and separated from the mounting base 16, the transmission of the external force to the housing 11 is blocked, and the housing 11 is prevented from being damaged.

[0013]

[Effect of the device]

 As described above, according to the mounting structure for a vehicle lamp of the present invention, even if an external force is applied to the lamp mounting portion of the vehicle body due to a collision or the like, the external force is not transmitted to the housing of the vehicle lamp. Damage is prevented.

Therefore, since it is only necessary to replace the broken parts without replacing the entire vehicle lamp, the economical burden on the user is reduced and the replaceability is good. Further, as described above, since the housing is not damaged, rainwater or the like does not enter the housing.
