Abstract

The invention relates to a rotating plate unit and a production method thereof. The rotating plate unit for a lidar device includes a disk-shaped stator and disk-shaped rotor with respective disk-shaped surfaces that are parallel to and at a distance from each other along a central axis; and a contactless transmission system between the stator and the rotor, which has pairs of mutually corresponding transmission elements, a first transmission element of a respective pair being situated on the surface of the stator facing the rotor and the associated second transmission element of the respective pair in each case being situated on the surface of the rotor facing the stator, the mutually corresponding transmission elements of a pair being at least sectionally situated at a distance and across from each other during a rotation of the rotor; the pairs of individual transmission elements of the transmission system being situated in spatial separation from one another along the radius of therotating plate unit.

Description

technical field [0001] The invention relates to a rotary disk unit and a method for manufacturing a rotary disk unit. In particular, the invention relates to a rotary disk unit with a contactless transfer system between a stator and a rotor for a LiDAR device and a method for producing such a rotary disk unit. Background technique [0002] LiDAR devices will pioneer applications in enabling autonomous driving functions over the next few years. In order to cover large horizontal sensing angles between 150° and 360°, currently only mechanical laser scanners are known. In a first configuration, only the motor-driven deflection mirror rotates in a rotating mirror laser scanner whose maximum sensing range is limited to approximately 150°. For larger sensing ranges up to 360°, all electro-optical components are located on a motor-driven rotating disk or rotor. Most of the other electronic components are arranged on the corresponding stator. Here, the stator and the rotor toget...
