Compression device and sensor cleaning system including the same
View Patent ↗A sensor cleaning system for a hydrogen vehicle includes hydrogen as fuel and includes a compression device configured to operate by a flow of the hydrogen, and one or more nozzles configured to spray a compressed fluid generated by the compression device onto a sensor.
1 . A sensor cleaning system for a hydrogen vehicle using hydrogen as fuel, the system comprising:
a compression device configured to operate by a flow of the hydrogen; and
one or more nozzles configured to spray a compressed fluid generated by the compression device onto a sensor, wherein the compression device includes:
a turbine configured to rotate by the flow of the hydrogen;
a cam shaft rotatably connected to the turbine; and
a compressor configured to generate the compressed fluid by a rotation of the cam shaft.
2 . The system of claim 1 , wherein the compressor includes:
a piston compressible by the cam shaft; and
a spring mounted on the piston and compressed or extended by a movement of the piston.
3 . The system of claim 1 , wherein the compression device further includes a hydrogen channel through which the hydrogen which rotates the turbine flows.
4 . The system of claim 1 , wherein the hydrogen vehicle includes a fuel cell stack or a hydrogen engine.
5 . The system of claim 1 , wherein the sensor includes a light detection and ranging (LiDAR) sensor, a radio detection and ranging (RADAR) sensor, or a camera, disposed in the hydrogen vehicle.
6 . The system of claim 1 , wherein the compressed fluid is compressed air or a washer fluid.
7 . A hydrogen vehicle including a sensor cleaning system, the hydrogen vehicle comprising:
a compression device disposed on a line through which hydrogen is supplied from a hydrogen tank to a fuel cell stack or a hydrogen engine and configured to generate a compressed fluid through a flow of the hydrogen; and
one or more nozzles configured to spray the compressed fluid onto the sensor.
8 . The hydrogen vehicle of claim 7 , wherein the sensor cleaning system includes:
a fluid tank configured to store the generated compressed fluid and connected to the one or more nozzles;
an openable valve configured to allow or block a flow of the compressed fluid from the fluid tank to the one or more nozzles; and
a controller configured to control opening and closing of the valve.
9 . The hydrogen vehicle of claim 7 , wherein the compression device includes:
a turbine configured to rotate by the flow of the hydrogen;
a cam shaft rotatably connected to the turbine; and
a compressor configured to generate the compressed fluid by a rotation of the cam shaft.
10 . The hydrogen vehicle of claim 7 , wherein the sensor cleaning system does not include a separate compressor other than the compression device.
