Abstract

(57) [Summary] [Purpose] A vehicle lamp having a structure in which a hook 3b provided on a lens 3 is engaged with a notch 2b of an inner flange-like edge 2a provided along the periphery of a front opening of a lamp housing. The lens mounting structure is improved to make the shadow around the lens uniform over the entire circumference. [Structure] The notch 2b is provided in the inner flange-like edge 2a.
A light-shielding wall 2c is provided to cover the rear of the light-shielding wall 2c. This blocks the optical path passing through the cutout, so that the cutout no longer affects the appearance.

Description

[Detailed explanation of the idea]

This is a structure in which a lens 3 is attached. However, in this invention, the names of front and rear refer to the direction of light projection. is before. In other words, what is the front and back regarding the direction of travel of the vehicle in which this light should be installed? It's irrelevant. The AA cross section shown in FIG. 4 above is shown in FIG. 5(A). Front of lamp housing 2 An inner flange-like edge 2a is formed around the opening, and the lens 3 is attached to this edge 2a. a for positioning in the front-rear direction (left-right direction in the figure). 3a is , a prism formed on the inner surface of the lens 3.

0003 FIG. 5(B) shows a BB cross section in FIG. 4. In this cross section, the hook 3b of the lens 3 is It is appearing. A schematic perspective view depicting the vicinity of this hook 3b is shown in FIG. A notch 2b corresponding to the hook 3b is provided in the edge 2a of the lamp housing 2. , the hook 3b engages with the edge of this notch 2b.

[Problem that the idea aims to solve]

The lens 3 emits light when the high mount stop lamp 1 shown in Fig. 4 is turned on. Figure 7 shows the state in which this occurs. Around this lens 3, the shadow 4 of the above-mentioned edge 2a is dark. It is visible in the shape of However, the edge 2a described with reference to FIG. 5(A) has a notch as shown in FIG. 2b, this notch does not cast a shadow. As a result, Figure 7 shows As shown, a shadow cut 4a is created in the edge shadow 4. The inventor investigated the psychological influence that the existence of the above shadow cut has on the appearance. However, the product value was significantly reduced, saying that it felt like a tooth had been pulled out. It turned out that there was.

[0005] This invention was devised in view of the above-mentioned circumstances. A lens is attached to cover the opening, and the lens is brought into contact along the opening. An inner flange-like edge is formed on the periphery of the lens for mounting multiple lenses. A hook is provided, and a cutout for hook engagement is provided in the inner flange-like edge. We have improved the lens mounting structure of vehicle lamps and added functions related to lens mounting. The purpose is to prevent the occurrence of shadow cuts 4a as shown in Fig. 7 without causing any damage. shall be.

[0006]

[Means to solve the problem]

The present invention relates to a configuration for achieving the above purpose (preventing the occurrence of shadow cuts). The lens mounting structure has a lens mounted over the front opening of the lamp housing. An inner flange-like edge is formed along the opening to which the lens abuts. A plurality of mounting hooks are provided at the periphery of the lens, and the inner lens Vehicle lamp lens mounting structure with a hook engagement cutout on the flange-shaped edge In construction, A shape that covers the hook is provided on the rear side of the notch provided in the flange-like edge. It is characterized by the provision of a light-blocking wall.

[0007]

[Effect]

According to the above configuration, the notch for hook engagement provided on the inner flange-like edge Since the light-shielding wall is provided on the rear side, the light path passing through the notch is blocked by the light-shielding wall. For this reason, in FIG. 7 (conventional example), the shadow cut 4 corresponding to the above cutout is a looked bright, but the back side of the notch was covered with a light-shielding wall and became dark, and the shadow The cut (bright area) 4a disappears.

[0008]

【Example】

FIG. 1 shows one embodiment of the present invention, and is a sectional view corresponding to FIG. 5(B) in the conventional example. (A sectional view taken along a plane passing through the hook 3b). This embodiment is an improvement of the above-mentioned conventional example by applying the present invention. Those with the same drawing reference numbers as in FIGS. 4 to 7 showing examples are the conventional examples. It is the same or similar component as in . FIG. 2 is a schematic perspective view depicting the vicinity of the hook 3b in FIG. 1 (embodiment). This FIG. 2 is a diagram corresponding to FIG. 6 in the conventional example.

[0009] An edge 2 configured in the form of an inner flange along the front opening of the lamp housing 2 A light shielding wall 2c that covers the rear of the notch 2b of a is integrated with the lamp housing 2. They are installed in series and injection molded with synthetic resin material. This allows illumination from the back side of lens 3. The emitted light does not reach the notch 2b (FIG. 2). Therefore, in FIG. 3, which depicts the front view, the lens 3 is surrounded by a dark frame. Edge shadow (shadow of inner flange-like edge 2a) 4 is recognized and corresponds to notch 2b Does not produce bright spots.

0010 As understood from FIG. 1, the light shielding wall 2c is spaced apart from the hook 3b and covers the rear thereof. Therefore, there is no risk of interfering with the operation of attaching and detaching the hook 3b.

[0011]

[Effect of the idea]

According to the lens mounting structure according to the present invention, the shadow part that occurs around the lens is It is uniform over the entire area, and there are no shadow cuts, so there is no discomfort in the appearance, and the product price is lower. High value. Moreover, the lens attachment function using the hook is not hindered. .
