Abstract

An electronics housing assembly is disclosed. In some embodiments, the electronics housing is attached to a vehicle to house a sensor of the vehicle (e.g., a LIDAR). The electronics housing includes a fixed body structure, a movable body structure, a motor operatively coupled to the movable body structure, a positioner sensor coupled to the fixed body structure, and a sensor bracket attached to the movable body structure and configured to attach to a sensor. In some embodiments, the positioner sensor is used to detect the position of the movable body structure and the sensor.

First claim

What is claimed is:

1. An electronics housing assembly, comprising:
a fixed body structure;
a movable body structure;
a motor operatively coupled to the movable body structure;
a positioner sensor coupled to the fixed body structure, the positioner sensor configured to detect the position of the moveable body structure;
a sensor bracket attached to the movable body structure and configured to attach to a sensor; and
a plurality of mounting brackets, the mounting brackets comprising bracket springs encircling bracket pins, wherein the electronics housing assembly deflects in response to an applied force applied in the direction along which the bracket pins are disposed.

2. The electronics housing assembly of claim 1 , further comprising:
a magnet mounted to the movable body structure; and
a sensing circuit operatively coupled to the positioner sensor.

3. The electronics housing assembly of claim 2 , wherein:
the positioner sensor comprises a magnetic potentiometer,
the resistance of the magnetic potentiometer varies with the position of the magnet mounted to the movable body structure, and
the sensing circuit outputs a signal indicative of the resistance of the magnetic potentiometer.

4. The electronics housing assembly of claim 1 , wherein the motor comprises a linear actuator.

5. The electronics housing assembly of claim 1 , further comprising:
a limit switch configured to detect the position of the movable body structure and stop the operation of the motor when the position of the movable body structure reaches a threshold position.

6. The electronics housing assembly of claim 5 , wherein:
the positioner sensor and the limit switch are disposed inside of the fixed body structure.

7. The electronics housing assembly of claim 1 , further comprising:
one or more support rails disposed parallel to a motor shaft of the motor, the one or more support rails connected to the movable body structure and the fixed body structure and capable of expanding to the height of the movable body structure.

8. The vehicle of claim 1 , wherein the sensor housing assembly further comprises:
a magnet mounted to the movable body structure; and
a sensing circuit operatively coupled to the positioner sensor.

9. The electronics housing assembly of claim 8 , wherein:
the positioner sensor comprises a magnetic potentiometer,
the resistance of the magnetic potentiometer varies with the position of the magnet mounted to the movable body structure, and
the sensing circuit outputs a signal indicative of the resistance of the magnetic potentiometer.

10. A vehicle comprising:
a sensor; and
a sensor housing assembly, comprising:
a fixed body structure;
a movable body structure;
a motor operatively coupled to the movable body structure;
a positioner sensor coupled to the fixed body structure, the positioner sensor configured to detect the position of the moveable body structure;
a sensor bracket attached to the movable body structure and attached to the sensor; and
a plurality of mounting brackets, the mounting brackets comprising bracket springs encircling bracket pins; wherein the sensor housing assembly deflects in response to an applied force applied in the direction along which the bracket pins are disposed.

11. The vehicle of claim 10 , further comprising:
a main chassis, wherein the sensor housing assembly is attached to the main chassis at a position beneath a front hood of the vehicle.

12. The vehicle of claim 10 , wherein the sensor is a LIDAR.

13. The vehicle of claim 10 , further comprising:
a light ring disposed circumferentially around the sensor.

14. The vehicle of claim 10 , further comprising:
one or more support rails disposed parallel to a motor shaft of the motor, the one or more support rails connected to the movable body structure and the fixed body structure and capable of expanding to the height of the movable body structure.

15. The vehicle of claim 10 , further comprising:
a limit switch configured to detect the position of the movable body structure and stop the operation of the motor when the position of the movable body structure reaches a threshold position.

16. The vehicle of claim 15 , wherein:
the positioner sensor and limit switch are disposed inside of the fixed body structure and the movable body structure.
