2 is a sectional view of a vehicle headlining lamp assembly 1 according to the invention. As shown in FIG. 2, the vehicle headlining lamp assembly 1 according to the present invention includes a housing 100 and a lens 200.

The housing 100 is formed in a box shape having one surface opened, and a bulb (not shown) is installed therein. The housing 100 is inserted into the mounting hole of the headlining 2 and directly coupled to the headlining 2. That is, the first support part 110 and the second support part 120 which are spaced at predetermined intervals on one side edge portion of the housing 100 are protruded to form a tong shape, respectively, the first support part 110 and the second As the headlining 2 is fitted to the support 120, the housing 100 may be fixed to the headlining 2. In this case, the first support part 110 and the second support part 120 may have an approximately 'c' shaped cross section.

However, in the case of forming a 'c' shaped cross section, when the housing 100 is fitted to the headlining 2, a locking phenomenon is often generated, and thus the work is not easy. Thus, as shown in Figure 2, the second support portion 120 is preferably bent from the edge of the housing 100 to form a predetermined inclination with the lower surface of the headlining 2, the housing 100 It is more preferable to protrude horizontally from the edge of the bent. Due to this, not only a sufficient space for the headlining 2 to be fitted between the first support part 110 and the second support part 120 without a phenomenon is secured, but also rather than being simply formed in a 'c' shape. Fixing force with (2) can be strengthened. And, if the groove in which the end of the second support portion 120 is formed in the lower surface of the headlining 2 is formed, the fixing force may be further strengthened.

In addition, the first support 110 is projected horizontally from the edge of the housing 100, it is preferable that the end is bent at a predetermined inclination. The end of the first support 110 is bent so as to form a predetermined inclination in the upward direction so that the headlining 2 can be easily inserted without being caught when the headlining 2 is fitted.

On the other hand, the other edge portion of the housing 100 is protruded to form a third support portion 130 is supported on the lower surface of the headlining (2). The third support 130 may also be formed to protrude horizontally, but is preferably bent from the other edge of the housing 100 to form a predetermined slope with the lower surface of the housing 100. At this time, the edge portion and the third support portion 130 of the housing 100 forms a cross section of a substantially 'V' shape. As such, the bending of the third support part 130 of the housing 100 is intended to strengthen the fixing force of the housing 100 and the headlining 2 as in the case of the second support part 120. In addition, as in the case of the second support portion 120, if the groove is formed in the lower surface of the headlining 2, the end of the third support portion 130 can be inserted and fixed may be further strengthened.

In addition, the housing 100 has a locking groove 140 is formed on the inner surface of one side edge portion and the through-hole portion 150 is formed on the other side. The locking groove 140 is not particularly limited in size, but is preferably formed long along the inner surface of the locking groove 140 so that the coupling force with the lens 200 can be strengthened, and the through hole 150 is also described below. It is preferable that the protrusion 220 is formed to be as long as the locking groove 140 so that the bearing force on the upper surface of the headlining 2 can be strengthened.

The lens 200 has a box-shaped shape with one surface opened, and is inserted into and coupled to the housing 100, and a light bulb installed inside the housing 100 emits light to the room through the lens 200. Done. The lens 200 is provided with a protrusion 210 corresponding to the locking groove 140 of the housing 100 on an outer surface of one side edge portion so as to be coupled to the inside of the housing 100 and on the outer surface of the other edge portion. A protrusion 220 is formed to penetrate the through hole 150 of the housing 100 and be seated on the upper surface of the headlining 2. That is, the protrusion 210 of the lens 200 is fixed to the locking groove 140 of the housing 100 and the protrusion 220 of the lens 200 penetrates the through-hole 150 of the housing 100 to the head. It is to be seated on the upper surface of the lining (2).

Protruding portion 220 of the lens 200 seated on the upper surface of the headlining (2) together with the third support portion 130 of the housing 100 to press and fix the headlining 2 like a tong from the top and bottom, It serves as the first support 110 and the second support 120 of the housing 100. That is, when the lens 200 is inserted into the housing 100 and the protrusion 210 is coupled to the locking groove 140, the lens 200 is elastically resilient so that the protrusion 220 is opposite the headlining 2. In close contact with the top surface, the headlining 2 is pressed downward. At this time, the sagging of the headlining 2 is prevented by the third support 130 of the housing 100. That is, the first support part 110 and the second support part 120 of the housing 100 are firmly fixed to the headlining 2 as described above, and the third support part 130 is the lower part of the headlining 2. In close contact with the surface, the headlining 2 is pushed upward. The protrusion 220 of the lens 200 and the third support 130 of the housing 100 may be fixed to one side of the mounting hole of the headlining 2. Accordingly, the housing 100 is fixed to the headlining 2 by the first support 110 and the second support 120 of the housing 100, and the protrusions 210 and the protrusions 220 of the lens 200 are fixed to each other. The housing 100 and the lens 200 are completely fixed by the third support part 130 of the housing 100.

On the other hand, since the protrusion 220 of the lens 200 penetrates the through-hole 150 of the housing 100 and is able to move back and forth along the through-hole 150, the protrusion 220 of the lens 200 is formed in the housing 100. The through hole 150 may be detached from the lens 200, and the lens 200 may be separated from the housing 100. Therefore, the ends of the protrusions 220 of the lens 200 may be extended so that the separation of the lens 200 and the housing 100 may be prevented, and the protrusions 220 of the lens 200 which are thus expanded. The end of the lens 200 is not separated from the housing 100 because it does not pass through the through-hole portion 150 of the housing 100.

3A to 3C are diagrams illustrating a mounting process of the vehicle headlining lamp assembly 1 according to the present invention, and the mounting process of the vehicle headlining lamp assembly 1 will be described with reference thereto.

As shown in FIG. 3A, first, the headlining 2 is inserted into the first support part 110 and the second support part 120 of the housing 100 while inserting the housing 100 into a mounting hole (not shown). To be fitted. At this time, the headlining 2 should be pushed in at a slight inclination so that the first support 110 and the second support 120 of the housing 100 are easily fitted. In addition, as described above, the first support part 110 is bent at an end thereof to form a predetermined inclination in the upward direction, and since the second support part 120 is formed to protrude horizontally and is bent, the first support part 110 is formed. ) Or the second support portion 120 and the headlining 2 can be prevented. Thus, the state in which the headlining 2 is fitted to the first support 110 and the second support 120 is as shown in FIG. 3B, and the second support 120 and the third support of the headlining 2 The housing 100 can be firmly fixed to the headlining 2 because it is inclined with the lower surface.

Next, the lens 200 is inserted into and coupled to the housing 100 fixed to the headlining 2. As shown in FIG. 3B, since the end of the protrusion 220 of the lens 200 penetrating the through-hole part 150 of the housing 100 is extended, the housing 100 has the headlining 2. When the lens 200 is fixed to the lens 200, the lens 200 is not separated from the housing 100, but is caught in the housing 100 by the protrusion 220 of the lens 200. At this time, while pushing the protrusion 220 of the lens 200 into the through hole 150 of the housing 100, the protrusion 210 of the lens 200 is pushed into the locking groove 140 of the housing 100 to be coupled. Be sure to Here, in order to couple the protrusion 210 of the lens 200 to the locking groove 140 of the housing 100, the edge portion where the protrusion 210 of the lens 200 is formed should be slightly pushed inward of the lens 200. However, since the lens 200 is usually made of a plastic material and somewhat elastic, a large force is not required. At this time, as shown in FIG. 3, the protrusion 220 of the lens 200 is seated on the upper surface of the headlining 2, and the protrusion 220 of the lens 200 and the third of the housing 100 are disposed. Since the support 130 presses the headlining 2 up and down like a forceps, the lens 200 and the housing 100 are completely fixed. In this process, the lamp assembly 1 is mounted on the headlining 2.

On the other hand, when the lamp assembly 1 mounted as described above is to be replaced or maintained, the lamp assembly 1 can be removed from the headlining 2 in the reverse order of the mounting process. First, when the edge portion in which the protrusion 210 of the lens 200 is formed is pushed inward of the lens 200, the protrusion 210 of the lens 200 is removed from the locking groove 140 of the housing 100. As shown in FIG. 2, the lens 200 descends downward in the drawing. At this time, the end of the protrusion 220 of the lens 200 penetrating the through hole part 150 of the housing 100 is caught by the through hole part 150 of the housing 100, so that the lens 200 is connected to the housing 100. It is not separated from.

Then, when the third support 130 of the housing 100 is slightly pulled downward in the drawing and simultaneously flows to the left in the drawing, the first support 110 and the second support 120 of the housing 100 are headed. It can be separated from the lining 2. At this time, the edge portion of the housing 100 in which the third support portion 130 is formed maintains a predetermined distance between the headlining 2 and the housing 100 as shown in FIG. 3B. It can be moved. In addition, since the end of the first support 110 of the housing 100 is bent and the second support 120 is bent, as in the case of the mounting, the headlining 2 can be easily separated. have. In this manner, the lamp assembly 1 is removed from the headlining 2.

As described above, according to the vehicle headlining lamp assembly according to the present invention, since the lens and the housing can be mounted and removed only, the headlining can be easily mounted and removed without a separate tool.

In addition, since it can be mounted on the headlining only by the housing and the lens without a separate component such as a bolt or a nut, there is an effect of reducing the cost of reducing the number of parts.

In addition, if only the mounting hole of a predetermined size is formed in the headlining can be easily installed, the installation position can be varied.
