Radar coupler and method for assembling the same
The present embodiments relate to a radar coupler and a method for assembling the same. More specifically, there may be provided a radar coupler and a method for assembling the same, which may prevent a radar housing from escaping off a bracket when the bracket and the radar housing are simultaneously fastened together through a coupling part provided in the radar housing without using a socket, thereby preventing quality degradation that would arise if a socket is used and saving manufacturing costs.
1 . A radar coupler, comprising:
a bracket having at least one protrusion projecting forward and mounted to a vehicle; and
a radar housing including a box-shape body in which a radar is built and at least one coupling part provided on an outer edge of the body, the coupling part including a coupling hole into which the protrusion of the bracket is fitted,
wherein the coupling part includes a first support having the coupling hole on an inner circumferential surface thereof and a second support,
wherein the first support extends outward from the coupling hole, and a first side of an outer circumferential surface of the first support is connected with the body,
wherein the second support extends forward along the coupling hole,
wherein the at least one protrusion include a first protrusion, a second protrusion, and a third protrusion,
wherein the coupling part includes a first coupling part having a first opening whose second side is open from the coupling hole in a first direction, a second coupling part having a second opening whose second side is open from the coupling hole in a second direction different from the first direction, and a third coupling part, and
wherein the first protrusion and the second protrusion slide and are fitted into the first opening and the second opening, and the third protrusion is press-fitted in the coupling hole of the third coupling part.
2 . The radar coupler of claim 1 , wherein the coupling part further includes a third support extending forward and rearward from an end of a second side of the first support.
3 . The radar coupler of claim 2 , wherein the coupling part further includes a plurality of fourth supports spaced apart from each other and connecting a front surface of the first support and an outer circumferential surface of the second support.
4 . The radar coupler of claim 1 , wherein the protrusion is provided in a pillar shape, and wherein a portion where the first support and the second support are connected to each other is provided with an inclined portion where the coupling hole increases in diameter rearward.
5 . The radar coupler of claim 4 , wherein an end of the protrusion is provided with a protruding end radially projecting from the body, wherein a seating groove is formed in an inner circumferential surface of the second support to rest the protruding end, and wherein the seating groove has the same curvature as the protruding end.
6 . The radar coupler of claim 1 , wherein the coupling part is provided with an opening whose second side is open from the coupling hole.
7 . The radar coupler of claim 6 , wherein a width of the opening is smaller than a diameter of the coupling hole.
8 . The radar coupler of claim 1 , wherein among the at least one coupling part, the first coupling part is disposed at one of four corners of the body, and the second coupling part is disposed at a corner in a diagonal direction from the first coupling part.
9 . The radar coupler of claim 1 , wherein at least one of the at least one protrusion has a screw portion formed along an outer circumferential surface of a lower end thereof, and wherein the screw portion is fitted into a fastening hole formed in the bracket.
10 . A method for assembling a radar coupler, comprising:
a first axis coupling step of sliding and fitting a first opening being open in a first direction and provided in a radar housing over a first protrusion provided in a bracket;
a second axis coupling step of sliding and fitting a second opening being open in a second direction different from the first direction and provided in the radar housing over a second protrusion provided in the bracket by rotating the radar housing in a tilted state of the radar housing; and
a third axis coupling step of horizontally placing the radar housing on the bracket and press-fitting a third protrusion provided in the bracket into a through hole.
11 . A radar coupler, comprising:
a bracket having at least one protrusion projecting forward and mounted to a vehicle; and
a radar housing including a box-shape body in which a radar is built and at least one coupling part provided on an outer edge of the body, the coupling part including a coupling hole into which the protrusion of the bracket is fitted,
wherein the coupling part includes a first support having the coupling hole on an inner circumferential surface thereof and a second support,
wherein the first support extends outward from the coupling hole, and a first side of an outer circumferential surface of the first support is connected with the body,
wherein the second support extends forward along the coupling hole,
wherein the at least one protrusion include a first protrusion and a second protrusion,
wherein the coupling part includes a first coupling part having a first opening whose second side is open from the coupling hole in a first direction, a second coupling part having a second opening whose second side is open from the coupling hole in a second direction perpendicular to the third direction,
wherein the first protrusion and the second protrusion slide and are fitted into the first opening and the second opening.
