Abstract

An optical module of a Light Detection and Ranging (LiDAR) module for a vehicle can include a frame, a front plate, a rear plate, and a transmission module. The frame can include a base, four pillars extending from the base, and four beams extending between the pillars opposite the base. The transmission module can include a chassis, a laser module and an optical lens module. The front plate and rear plate can be coupled to the frame to define a support structure. The transmission module may be secured to the support structure by slidably coupling the chassis of the transmission module to the front plate and the rear plate, and securing the chassis to at least one of the front plate and the rear plate with a fastener so that the fastener and the slidable coupling restrain the transmission module to the support structure in six degrees of freedom.

Dependent claims

A method of assembling an optical module of a LiDAR system, the method comprising:

providing a frame comprising:
a base;
a front left pillar extending from the base;
a front right pillar extending from the base;
a rear left pillar extending from the base;
a rear right pillar extending from the base;
a top front beam extending between the front left pillar and the front right pillar;
a rear front beam extending between the rear left pillar and the rear right pillar;
a top left beam extending between the front left pillar and the rear left pillar;
and
a top right beam extending between the front right pillar and the rear right pillar, wherein the frame is monolithic;
fixedly coupling a front plate to the base and the top front beam so that the front plate contacts the front left pillar;
and
fixedly coupling a rear plate to the base and the top right beam, wherein the frame, the front plate and the rear plate define a support structure;
slidably coupling a transmission module to the support structure, wherein the slidable coupling restrains the transmission module to the support structure in five degrees of freedom, and wherein the transmission module comprises a chassis, a laser module and an optical lens module;
and
securing the chassis to at least one of the front plate and the rear plate with a first fastener so that the first fastener and the slidable coupling restrain the transmission module to the support structure in six degrees of freedom.
