Abstract: Provided are a motor assembly for a LiDAR, a LiDAR, and a carrier system. The motor assembly includes: a mounting bottom plate provided with a stator seat positioning groove; a circuit board assembled in a positioning manner to the mounting bottom plate; a stator seat located in the stator seat positioning groove and assembled in a positioning manner to the stator seat positioning groove, the stator seat being provided with a stator positioning protrusion protruding away from the mounting bottom plate; and a wound stator sleeved on the stator positioning protrusion and assembled in a positioning manner to the stator positioning protrusion.

Abstract: The present disclosure provides a driving assembly, a LiDAR, and a carrier system. The driving assembly comprises: a shaft comprising a first end and a second end; a first bearing sleeved on an outer side of the shaft and located close to the first end; a second bearing sleeved on the outer side of the shaft and located close to the second end; a stator sleeved on the outer side of the shaft and located between the first bearing and the second bearing; and a rotor assembly fixedly connected to an outer ring of the first bearing and an outer ring of the second bearing and arranged corresponding to the stator, the rotor assembly being configured to be connected to the optical assembly. The spatial arrangement of the driving assembly of the LiDAR improves the stability of the LiDAR during rotation, and reduces the wear of parts and components.

Abstract: The present disclosure provides a transmitter module, a transceiver module for a LiDAR, a LiDAR, and a system. The transmitter module includes a laser emitter, an optical splitter, and a collimation assembly. The laser emitter is configured to emit a laser beam. The optical splitter is located in an outgoing path of the laser beam and is configured to receive the laser beam and split the laser beam into a plurality of split beams. The collimation assembly is located in outgoing paths of the split beams and is configured to receive the split beams and collimate the split beams into collimated beams. This enables the LiDAR to implement multi-line scanning and detection at low cost.

Abstract: The present disclosure discloses a motor for an on-vehicle LiDAR, the vehicle-borne LiDAR, and a vehicle. The motor comprises a rotor assembly, a flat rubber washer and an optical reflecting mirror, wherein the rotor assembly comprises a housing and a fastening ring, wherein an inner cylinder of the housing is provided with a welding portion at the periphery, and an air slot is provided between the welding portion and the inner cylinder of the housing; and the welding portion is fixed to the fastening ring by means of laser welding. Laser welding is used to fix the fastening ring to the housing of the motor.
