Vehicular sensor device
The present disclosure relates to a vehicular sensor device, the vehicular sensor device including a housing having an opening and having an internal space inside, a substrate accommodated inside the housing, a detector mounted on the substrate, a cover coupled to the housing and covering the opening, and a sealing unit arranged between the cover and the housing.
1 . A vehicular sensor device comprising:
a housing having an opening and having an internal space inside of the housing;
a substrate accommodated inside the housing;
a detector mounted on the substrate;
a cover coupled to the housing and covering the opening; and
a sealing unit arranged between the cover and the housing,
wherein one or more fusion-subject protrusions protrude upward on the housing, and one or more coupling holes of the substrate are positioned corresponding to the one or more fusion-subject protrusions, and
wherein the one or more fusion-subject protrusions pass through the one or more coupling holes of the substrate and are melted to connect the substrate to the housing.
2 . The vehicular sensor device of claim 1 , wherein one or more hooks are protrusively formed on an outer surface of the housing, and one or more couplers are coupled to the cover by being inserted thereinto.
3 . The vehicular sensor device of claim 2 , wherein the coupler comprises:
a coupling body in which a through-hole into which the hook is inserted is formed, the coupling body provided on an edge of the cover; and
a blocking portion onto which the hook inserted into the through-hole is hooked, the blocking portion being provided on one side of the coupling body.
4 . The vehicular sensor device of claim 2 , wherein a plurality of hooks are arranged along a circumference of the housing, and a plurality of couplers are arranged along a circumference of the cover.
5 . The vehicular sensor device of claim 1 , wherein the detector is a radar sensor or a camera sensor.
6 . The vehicular sensor device of claim 1 , wherein a seating part is formed along an edge of an inner surface of the cover by recessing thereinto, and the sealing unit is seated on an inner side of the seating part.
7 . The vehicular sensor device of claim 6 , wherein the sealing unit is O-ring formed of an elastic material in a shape of a ring.
8 . The vehicular sensor device of claim 7 , wherein the sealing unit is pressed between the seating part and an edge of the housing.
9 . The vehicular sensor device of claim 8 , wherein one or more ribs are protrusively formed on a surface of the seating part to press against the sealing unit.
10 . The vehicular sensor device of claim 9 , wherein a plurality of ribs are arranged along the surface of the seating part.
11 . The vehicular sensor device of claim 1 , further comprising:
a label attached on an outer surface of the cover; and
a base plate having a central hole, the housing seated on the base plate and the base plate coupled to the cover.
