Sensor attachment bracket and sensor assembly
An object of the present disclosure is to provide a sensor attachment bracket and a sensor assembly capable of accurately attaching a sensor. A sensor attachment bracket and a sensor assembly include a base bracket formed of a plate-shaped member and a sensor-mounting-position ensuring bracket formed by bending a plate-shaped member in a hat shape, in which a flange portion of the sensor-mounting-position ensuring bracket and the base bracket are joined by spot welding.
1 . A sensor attachment bracket, comprising:
a base bracket formed of a plate-shaped member and attached to a vehicle body; and
a sensor-mounting-position ensuring bracket formed by bending a plate-shaped member in a hat shape,
wherein
a flange portion of the sensor-mounting-position ensuring bracket and the base bracket are joined to each other by spot welding;
the sensor-mounting-position ensuring bracket includes a plurality of hat portions formed so as to include lateral flange portions formed at both end portions, a plurality of top surface portions, and one or more central flange portions formed between the plurality of top surface portions;
the sensor-mounting-position ensuring bracket is joined to the base bracket by the spot welding at one location on each of the lateral flange portions and each of the one or more central flange portions;
a plurality of sensors are attached to the top surface portions respectively; and
a total number of the spot welds joining the sensor-mounting-position ensuring bracket and the base bracket is one greater than a total number of the sensors attached to the sensor-mounting-position ensuring bracket.
2 . The sensor attachment bracket according to claim 1 , wherein normal directions of the plurality of top surface portions are different from each other.
3 . The sensor attachment bracket according to claim 1 , further comprising: at least one sensor pedestal bracket fixed to at least one the plurality of the top surface portions of the sensor-mounting-position ensuring bracket by spot welding.
4 . A sensor assembly, comprising:
the sensor attachment bracket according to claim 3 ;
a resin plate attached to the sensor pedestal bracket;
a sensor attached to the resin plate;
a harness connected to the sensor; and
a resin-made cover that covers the sensor.
5 . The sensor assembly according to claim 4 , wherein:
a notch portion is formed in the base bracket, and
the harness is locked to the notch portion.
6 . The sensor assembly according to claim 5 , wherein:
a frame-shaped bracket in which an opening portion is formed is attached to a surface of the base bracket opposite to a side to which the sensor is attached, and
the frame-shaped bracket closes an opening portion of the notch portion.
