Description

[Detailed explanation of the idea]

0001

[Industrial application field]

TECHNICAL FIELD The present invention relates to a vehicle lamp that is applied to a vehicle headlamp or the like.

0002

[Conventional technology]

Conventional vehicle lamps have been constructed as shown in FIGS. 6 to 8. That is, the housing A fitting groove 2 having a substantially U-shaped cross section is provided on the open end side of the circumferential wall of the ring 1, and this fitting An engagement hole 4 is bored in the outer wall 3 of the groove 2. In addition, an engaging protrusion is provided on the outer surface of the peripheral wall of the lens 5. 6 and a stopper wall 7 are provided protrudingly.

0003 Then, apply the hot melt 8 of the housing 1 to the open end side of the peripheral wall of the lens 5. The lens 5 is inserted into the filled fitting groove 2, and the engagement protrusion 6 of the lens 5 is inserted into the engagement hole of the housing 1. 4 and abutting the end of the outer wall 3 of the fitting groove 2 against the stopper wall 7, In this configuration, a lens 5 is attached and held in a housing 1.

0004

[Problem that the idea aims to solve]

In such a conventional vehicle lamp, the fitting groove 2 of the housing 1 is engaged with the outer wall 3. Since a mating hole 4 is provided and an engaging protrusion 6 is provided on the peripheral side wall of the lens 5, the engaging protrusion 6 is When engaging the engagement hole 4, the outer wall 3 of the engagement groove 2 of the housing 1 The housing 1 is fitted by being forcibly expanded outward and deformed. A gap is created between the outer wall 3 of the matching groove 2 and the peripheral side wall of the lens 5, and the housing is There was a risk that rainwater, etc. would infiltrate into Room 1.

[0005] Furthermore, an engagement hole 4 is provided on the housing 1 side, and an engagement protrusion 6 is provided on the lens 5 side. Therefore, these molds require a sliding structure for die cutting. As a result, the mold structure was complicated and the mold manufacturing cost was high.

[0006] This invention was created in view of the above circumstances, and it ensures that the lens is securely attached to the housing. Not only can it be maintained, there is no risk of rainwater etc. entering the housing, and it is A vehicle light with a simple mold structure for the housing and lens, and the mold production cost is low. is intended to provide.

[0007]

[Means to solve the problem]

In order to achieve the above object, the vehicle lamp of the present invention has an open end of the peripheral side wall of the housing. An engaging protrusion is provided protruding from the end surface of the outer wall of the fitting groove with a substantially U-shaped cross section provided on the side, and the opening of the circumferential side wall is The outer surface of the peripheral side wall of the lens whose mouth end side is fitted into the fitting groove of the housing is provided with the A stopper wall is provided in a protruding manner, and the end surface of the outer wall of the fitting groove comes into contact with the stopper wall. An engagement hole is formed into which the engagement protrusion of the housing engages, and the engagement protrusion is engaged with this engagement hole. By mating, the lens is attached and held to the housing, and the engagement When the protrusion engages with the engagement hole, the protrusion may be displaced toward the inside of the housing. It is characterized by the following.

[0008]

[Effect]

Insert the engaging protrusion provided on the outer wall end of the fitting groove of the housing into the stopper wall of the lens. The lens is attached and held to the housing by engaging with the provided engagement hole. Ma In addition, the engagement protrusion is displaced toward the inside of the housing when it engages with the engagement hole. Therefore, no gap is created between the outer wall of the fitting groove of the housing and the peripheral side wall of the lens.

[0009]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

0010 Figure 1 is a front view of the main parts of the vehicle lamp according to the present invention, and Figure 2 is taken along line II-II in Figure 1. 3 is a sectional view taken along the line III-III in Fig. 1, and Fig. 4 shows the main components of the vehicle lamp in Fig. 1. FIG. 5 is an exploded perspective view of the part, and is a view similar to FIG. 2 in an exploded state.

[0011] In each figure, 10 is a housing, and the opening end side of the peripheral side wall of the housing is fitted with a substantially U-shaped cross section. A groove 11 is provided. The end surface of the outer wall 12 of this fitting groove 11 is provided with a gap in the circumferential direction. A plurality of engaging protrusions 13 are integrally protruded at intervals. This engagement protrusion 13 is On the outer surface of the tip of the rectangular plate-shaped main body 13a, the amount of protrusion gradually decreases toward the tip side. It is formed by integrally protruding a protrusion 13b having a sloped surface shape.

0012 The open end side of the peripheral side wall of the lens 14 is fitted into the fitting groove 11 of the housing 10. . The end surface of the outer wall 12 of the fitting groove 11 comes into contact with the outer surface of the peripheral side wall of this lens 14. A stopper wall 15 is integrally provided in a protruding manner. This stopper wall 15 has a housing An engagement hole 16 is bored into which ten engagement protrusions 13 engage.

[0013] Then, the open end side of the peripheral side wall of the lens 14 is attached to the hot melt of the housing 10. 17 into the fitting groove 11 filled with the housing 10, and then the engagement protrusion 13 of the housing 10 The end surface of the outer wall 12 of the fitting groove 11 of the housing 10 By contacting the stopper wall 15 of the lens 14, the lens is attached to the housing 10. 14 is attached and held.

[0014] When the attachment is held in this manner, the protrusion 13b of the engagement protrusion 13 passes through the engagement hole 16. When the main body 13a is displaced toward the inside of the housing 10 against elasticity, the protrusion 13b passes through the engagement hole 16, the main body 13a returns elastically and the protrusion 13a and the main body 13a is in a state where it is locked to the outer surface of the stopper wall 15.

[0015]

[Effect of the idea]

As described above, the vehicle lamp of the present invention has a cutout provided on the open end side of the peripheral wall of the housing. An engaging protrusion is provided protrudingly on the outer wall end surface of the approximately U-shaped fitting groove, and the open end side of the circumferential wall is On the outer surface of the peripheral side wall of the lens that is fitted into the fitting groove of the housing, there is a A stopper wall with which the end surface of the wall abuts is provided protrudingly, and the housing is engaged with the stopper wall. An engagement hole is formed in which the engagement projection engages, and the engagement projection is engaged with the engagement hole. The lens is mounted and held in the housing, and the engaging protrusion is arranged in the housing. It is characterized by being displaced toward the inside of the housing when engaging with the engagement hole. It is something that

[0016] Therefore, the engagement between the engagement protrusion and the engagement hole ensures that the lens is securely attached to the housing. Of course, the engagement protrusion can be held inside the housing when it engages with the engagement hole. Since the housing is displaced toward the There are no gaps and there is no risk of rainwater or the like entering the housing.

[0017] In addition, there is no need for the housing and lens molds to have a sliding structure. This simplifies the mold structure and reduces mold manufacturing costs.
