Abstract

A vehicular lamp fitting includes: a structure including a lamp housing and an outer lens attached to the lamp housing and forming a first space between the outer lens and the lamp housing; a lamp unit disposed in the first space; and the outer lens includes a recess recessed toward the lamp housing; wherein the vehicular lamp fitting further comprises: a radar cover that is detachably fixed to the structure in a state of covering the recess, and forms a second space between the radar cover and the recess; a bracket including one end detachably fixed to the structure, its opposite other end detachably fixed to the structure, and a bracket body provided between the one end and the other end and disposed in the second space; and a radar unit disposed in the second space in a state of detachably being fixed to the bracket body.

First claim

What is claimed is:

1 . A vehicular lamp fitting comprising:
a structure including a lamp housing and an outer lens attached to the lamp housing and forming a first space between the outer lens and the lamp housing; a lamp unit disposed in the first space and includes a light source that emits light that is irradiated through the outer lens; and the outer lens includes a recess recessed toward the lamp housing; wherein the vehicular lamp fitting further comprises: a radar cover that is detachably fixed to the structure in a state of covering the recess, and forms a second space between the radar cover and the recess; a bracket including one end detachably fixed to the structure, its opposite other end detachably fixed to the structure, and a bracket body provided between the one end and the other end and disposed in the second space; and a radar unit disposed in the second space in a state of detachably being fixed to the bracket body, and transmitting electromagnetic waves transmitted and received through the radar cover.

2 . A vehicular lamp fitting according to claim 1 , wherein
the radar unit has a case and an antenna housed in the case and is disposed at a predetermined position in the second space via a bracket so that electromagnetic waves can be transmitted and received through the radar cover, wherein the vehicular lamp fitting further comprises: a first fixing part positioned inside the second space and fixing one end of the bracket to the outer lens; and a second fixing part positioned outside the second space and fixing the other end of the bracket to the lamp housing.

3 . The vehicular lamp fitting according to claim 1 , wherein the first fixing part is a positioning rib provided on the outer lens, and fixes one end of the bracket to the outer lens in a state where one end of the bracket is sandwiched between the positioning rib and the outer lens.

4 . The vehicular lamp fitting according to claim 3 , wherein the positioning rib protrudes downwards, and an upper end of the bracket is inserted between the positioning rib and a front outer surface of the outer lens.

5 . The vehicular lamp fitting according to claim 4 , wherein the positioning rib is configured to maintain a gap between the radar cover and the recessed part.

6 . The vehicular lamp fitting according to claim 1 , wherein the other end of the bracket extends backwards through at least one bending part.

7 . The vehicular lamp fitting according to claim 6 , wherein the tip of the other end of the bracket is fixed to the lamp housing by the second fixing part.

8 . The vehicular lamp fitting according to claim 1 , wherein a stepped part is formed between the outer lens and a part of the radar cover located adjacent to the outer lens.

9 . The vehicular lamp fitting according to claim 8 , wherein an end of the radar cover adjacent to the outer lens bends backward through a bending part and thereby be disposed along the outer lens.

10 . The vehicular lamp fitting according to claim 1 , wherein the outer lens is transparent to visible light, and the radar cover is opaque to visible light.

11 . A radar structure comprising:
one end of a bracket detachably fixed to a structure including a lamp housing and an outer lens attached to the lamp housing and forming a first space between the outer lens and the lamp housing an outer lens; the other end of the bracket detachably fixed to the structure; a radar cover forming a space between the radar cover and the bracket in a state where the radar cover is detachably fixed to the bracket; and a radar unit that is disposed in the space in a state where the radar unit detachably fixed to the bracket.
