Description

[Detailed Description of the Invention] This invention relates to an interior light, and more specifically, mainly relates to a mounting structure for a reflector in an automobile interior light.

A reflector plate is attached to the base frame of an automobile interior light in order to increase the efficiency of indoor light distribution.

FIG. 1 shows a conventional reflector mounting structure, in which protrusions 3a and 3b are provided on the bottom plate portion 2 of a base frame 1 made of molded resin, and the protrusions 3a are provided on both ends of the reflector 4.

After drilling a pair of mounting holes 5a and 5b into which the projections 3b can be inserted, and arranging the reflecting plate 4 on the bottom plate part 2 so that the projections 3a and 3b can be inserted into the mounting holes 5a and 5b, The projections 3a and 3b which penetrate through the reflection plates 5a and 5b and protrude from the surface of the reflector plate are attached by applying heat.

For this reason, the projections 3a,
It requires two steps: arranging the protrusions 3a and 3b on the bottom plate 2 so as to insert them, and heat staking the protrusions 3a and 3b, resulting in poor work efficiency and high manufacturing costs.

This invention aims to eliminate the above-mentioned drawbacks, and its features are that the bottom plate of the base frame has a depth approximately equal to the thickness of the reflector, and a part of the reflector is fitted into the bottom plate. A recess of a size is formed, a reflector mounting piece is formed integrally with the base frame with a distance slightly shorter than the thickness of the reflector between the recess and the bottom surface of the recess, and the bottom surface A notch is formed in the part facing the reflector mounting piece, and the end of the reflector is clamped and fixed between the bottom surface of the recess and the reflector mounting piece, and the reflector can be attached to the base frame in a single step. The present invention provides a mounting structure for a reflector in an indoor light that can be implemented and reduce costs.

An embodiment of this invention shown in the drawings will be described in detail below.

Fig. 2 shows the structure for attaching the reflector to the base frame, in which the hood attachment part 1 occupies most of the base frame 11 constructed by injection molding with cast resin.
2 is the bottom plate part 1 for attaching the contact to which the boat-shaped light bulb is attached.
3, a recess 14 having a depth approximately equal to the thickness of the reflector and large enough to fit a part of the reflector is formed in the bottom plate portion 13, and a recess 14 is formed in the bottom plate 13, and the recess 14 has a depth approximately equal to the thickness of the reflector. A pair of reflector mounting pieces 16 are provided with an interval approximately equal to the thickness of the reflector between them.
is formed integrally with the base so as to be located in the center of the recess, and furthermore, a notch 17 is provided in a portion of the bottom facing the reflector mounting piece 16 to simplify the molding, thereby achieving a reflector mounting structure. It is something that has been shaped.

In the figure, 18 is a switch, 19 is a hood mounting hole, and 20 is a contact mounting portion.

The procedure for attaching a reflector using the above-mentioned reflector attaching structure will be explained with reference to FIGS. 3, 4 a-c, and 5.

First, one side of both longitudinal ends of a rectangular reflecting plate 21 with a substantially U-shaped reflecting surface 22 formed in the center of the mounting portion shown in FIGS. 1 and 4 a is plated on the surface of a metal plate. As shown in FIGS. 3 and 4, the lower corner is in contact with the lower surface of the rounded reflector mounting piece 16, and the other surface is in contact with the bottom surface 15 of the recess 14 in the direction of the arrow from one side as shown in FIG. and Figure 4C
As shown in FIG. 2, the reflective plate 21 is inserted until both ends thereof are completely inserted into the recess 14 provided in the bottom plate portion 13.

As a result, the reflector 21 is sandwiched between the bottom surface 15 of the recess 14 and the reflector mounting piece 16, and is fixed without falling off even when subjected to vibrations or the like.

After the above-mentioned reflection plate is attached, the first contact 23 is attached to the contact attachment part 20, and the bottom plate 25, in which the second contact 24 is attached to a part of the missing part of the bottom plate part 13, is attached. As shown in the figure, a boat-shaped light bulb 25 is connected between both contacts 23 and 24, and a conductor 26 is connected to the contact 23, and then connected to the hood of the penis frame 11 via a metal rim (not shown) to the vehicle body. Attachment part 12 has a hood (
(not shown) to complete the automobile interior light.

As mentioned above, this invention forms a recess in the bottom plate of the base frame with a depth approximately equal to the thickness of the reflector and a size that allows a part of the reflector to fit into it, and a space between the bottom of the recess and the bottom of the recess. A reflector mounting piece is formed integrally with the base frame with an interval slightly smaller than the thickness of the reflector plate, and a notch is formed in a portion of the bottom surface facing the reflector mounting piece, so that the recessed portion Since the end of the reflector is clamped and fixed between the bottom surface and the reflector mounting piece, the reflector can be attached to the base frame in one step, reducing costs and preventing defects when attaching the reflector. It has the advantage that it can be easily removed after installation by reversing the installation procedure.
