Abstract

A vehicle lamp with a separable multi-housing includes a housing that has a hole formation portion and a rear coupling portion on a rear surface of a housing body. The housing body has an internal space in which a module (e.g., an after-sale service target) is positioned and the internal space is covered by a lens. A light source unit can be securely held on the hole formation portion, and the module is taken out through the hole formation portion. The rear coupling portion is formed along an entire circumference of the hole formation portion at an edge of the housing body in such a manner as to have a protrusion structure. An operation of replacing the module can be performed through the hole formation portion. Particularly, a multi-housing can be coupled to the rear coupling portion using a replaceable housing meltable item, thereby covering the hole formation portion.

First claim

What is claimed is:

1 . A lamp with a separable multi-housing, the lamp comprising:
a module; and a housing including:
a housing body forming an internal space in which the module is positioned,
a hole formation portion formed on a rear surface of the housing body and configured to have a withdrawal hole through which the module is taken out of the internal space, and
a rear coupling portion protruding from an edge of the hole formation portion,
wherein a lens is positioned on a front surface of the housing body,
wherein the housing is coupled to a multi-housing using a fastening structure of the rear coupling portion, and wherein the fastening structure is formed by securely holding a housing adhesive, which seals an opening in the rear coupling portion, in a state of surrounding the multi-housing.

2 . The lamp of claim 1 , wherein the withdrawal hole is changed to a fracture portion in the hole formation portion, and
wherein the fracture portion is arranged inward from the rear coupling portion.

3 . The lamp of claim 2 , wherein the fracture portion is in a shape of a groove or a slit.

4 . The lamp of claim 1 , wherein the housing adhesive is a rubber-based meltable item that is responsive, waterproof and deconstructible.

5 . The lamp of claim 1 , wherein the multi-housing comprises:
a frame body covering a rear surface of the housing body; a module holding portion protruding from a middle section of the frame body and positioned on the hole formation portion or in the withdrawal hole; and a housing protrusion protruding from an edge of the frame body and surrounded by the housing adhesive sealing the opening in the rear coupling portion.

6 . The lamp of claim 5 , wherein the module is securely held on the module holding portion.

7 . The lamp of claim 1 , wherein a housing holding force enhancement structure is employed to couple the housing and the multi-housing.

8 . The lamp of claim 7 , wherein the housing holding force enhancement structure is formed by:
an auxiliary coupling portion protruding toward the rear coupling portion from an edge of the housing; a holding hole cut at a position, facing the auxiliary coupling portion, on the edge of the multi-housing; and a fastening member passing through the holding hole and engaged with the auxiliary coupling portion, wherein the auxiliary coupling portion and the fastening member are fastened to each other in a nut-bolt fastening manner.

9 . The lamp of claim 1 , wherein a lens adhesive is configured to seal an opening in a front coupling portion formed on the front surface of the housing body and configured to securely hold the lens in the housing.

10 . The lamp of claim 9 , wherein a lens protrusion that is surrounded by the lens adhesive protrudes from the lens.

11 . The lamp of claim 1 , wherein the module has a holding structure for the lens or the housing, and
wherein the holding structure of the module is formed by: a lateral-side holding portion protruding from a circumference of the module; a module bracket positioned to one side of the lateral-side holding portion; and a fastening member passing through a hole in the lateral-side holding portion and engaged with the module bracket.

12 . The lamp of claim 11 , wherein the lateral-side holding portion and the fastening member are fastened to each other in a nut-bolt fastening manner.

13 . The lamp of claim 11 , wherein an end portion of the lateral-side holding portion is formed within the module bracket in a manner that faces toward the housing or the lens.
