Description

[Detailed Description of the Invention] The present invention relates to a bumper-fitting lamp mounting structure.

Conventionally, lamps such as automobile fog lamps and combination lamps were fitted into and supported by bumpers, which made the bumper and lamp into a unit, reducing the number of parts and assembly man-hours. Efforts are being made to effectively utilize the rear space to improve the aesthetic appearance and improve the car's air resistance. Conventionally, this mounting structure includes providing a window into the bumper face into which the lamp is inserted, and attaching the lamp to a back beam provided on the back side of the bumper face via a bracket.
The lamp was facing the front of Banpa Face from the window. However, in this case, since the bumper face and the lamp are not fixed to each other, vibrations during driving cause the lamp to collide with the bumper face, resulting in damage to the lamp. On the other hand, as shown in FIG. 1, a lamp storage part 1a is formed in the bumper face 1, and a lamp is fitted into the storage part 1a and fixed to mounting pieces 1b protruding from the left and right side walls of the storage part 1a. Some models have a structure in which the bumper face 1 and the lamp are fixed to each other, but in recent years lamps have tended to become larger and heavier, and with large lamps, simply fixing the lamp to the mounting piece 1b is not enough to prevent vibrations during driving. This makes it impossible to prevent the lamp from vibrating relative to the bumper using the mounting piece 1b as a fulcrum, which also causes deterioration in visibility, disconnection, and damage to the lamp bulb.

The present invention solves the above-mentioned drawbacks, and aims to provide a mounting structure for a bumper-fitting lamp that prevents vibration of the lamp.
In order to achieve this object, the present invention has a structure in which a lamp accommodating part with a lamp mounting piece protruding from the bumper face is formed, a lamp is fitted into the accommodating part and fixed to the lamp mounting piece, and an interior is mounted on the bumper face. The present invention is characterized in that a support protrusion is formed on the shock absorbing material that contacts the outer periphery of the lamp.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 2 is a longitudinal cross-sectional view of a lamp mounting portion according to an embodiment of the present invention, FIG. 3 is a cross-sectional view thereof, and FIG. 4 is a front view of the lamp mounting portion of the urethane core.

The bumper face 1 has a lamp housing part 1a formed in the same manner as before, and mounting pieces 1b are provided protruding from the left and right side walls, and the lamp 2 is fitted into the housing part 1a, and the lamp 2 is fixed to the mounting piece 1b with bolts. . The bumper face 1 is equipped with a urethane core 3 which is a shock absorbing material, and the urethane core 3 is formed with a hole 3a through which the rear part of the lamp 2 is inserted at a position corresponding to the lamp storage part 1a of the bumper face 1. Support protrusions 3b are made to protrude inward from the upper and lower, left and right inner walls of the lamp 2, respectively, and their tips abut against the upper, lower, left and right outer peripheral side walls of the rear portion of the lamp 2, respectively. Further, 4 in FIG. 2 is a back beam, and the bumper assembly including the bumper face 1, lamp 2, and urethane core 3 is attached to the vehicle body by the back beam 4.

In this way, the lamp 2 is fixed to the bumper face 1 at the front with bolts, and at the same time, the urethane core 3 is in contact with the outer periphery of the lamp 2 and supported, so vibrations are absorbed by the urethane core 3 and the bumper face 1 of the lamp 2 vibration is prevented.

In the above embodiment, a total of four support protrusions 3b are formed on the upper, lower, left, and right inner walls of the lamp insertion hole 3a of the urethane core 3, and the tips thereof are brought into contact with the lamp 2. If the air permeability between the lamp 2 and the urethane core 3 is increased by partially pressing the outer periphery of the lamp 2, there is an advantage that the heat generated in the lamp 2 can be effectively discharged without accumulating in the storage portion 1a.

As specifically explained using one embodiment, according to the present invention, a shock absorbing material such as a urethane core inside the bumper face is brought into contact with the outer periphery of the lamp, thereby preventing vibration of the lamp while driving. is,
This can prevent deterioration of visibility and reduce failures such as wire breakage and lamp bulb damage.
