Vehicle Lidar sensor module

A vehicular lidar sensor module, the vehicular lidar sensor module comprising:

• a laser unit, the laser unit comprising a housing, a laser printed circuit board, a power circuit board, laser collimators and a first tension spring, wherein the first tension spring urges the laser collimators against respective reference surfaces of the housing, and wherein the first tension spring urges the power printed circuit board against the housing;
• wherein laser emitters of the laser printed circuit board are located at an end of respective laser collimators, and wherein the laser collimators collimate light emitted by the respective laser emitters so that collimated laser light is emitted from an end of the laser collimators opposite the end at which the laser emitters are located;
• a sensor unit, the sensor unit comprising a holder, receiver tubes and a second tension spring, wherein the second tension spring urges the receiver tubes against respective reference surfaces of the holder;
• wherein the holder of the sensor unit is attached at the housing of the laser unit, and wherein, with the holder attached at the housing, the receiver tubes are disposed along and adjacent to the laser collimators;
• a cover unit attached at the housing of the laser unit;
• wherein the sensor unit comprises sensors disposed at an end of respective receiver tubes, and wherein the sensors are attached at the holder via respective flexible attaching elements that allow for multiple-degrees of freedom of adjustment of the sensors relative to the receiver tubes;
• wherein, with the flexible attaching elements attached at the holder, the sensors are aligned relative to the respective laser collimators via the respective flexible attaching elements and are fixed in their aligned positions;
• and
• wherein the cover unit comprises a cover element and an electrical connector configured to electrically connect the vehicular lidar sensor module to a vehicle wire harness when the vehicular lidar sensor module is disposed at a vehicle equipped with the vehicular lidar sensor module.
