Hidden shaft type rotating device and manufacturing method thereof

Abstract

The invention discloses a hidden shaft type rotating device and a manufacturing method thereof. The hidden shaft type rotating device is used for installing a functional module and comprises a base assembly, a rotating assembly, a driving mechanism and a hidden shaft mechanism. The rotating assembly has a central region, an edge region located around the central region, and a central axis passingthrough the central region. The driving mechanism is arranged between the rotating assembly and the base assembly so as to drive the rotating assembly to rotate around the central axis. The hidden shaft mechanism is fixedly arranged in the edge region of the rotating assembly, so that a complete mounting space is formed between the hidden shaft mechanism and the central region of the rotating assembly, the functional module is mounted in the central region of the rotating assembly, and the rotating assembly drives the functional module to rotate around the central axis.

Description

technical field [0001] The present invention relates to the technical field of complete machine or equipment operation platform, and more specifically relates to a hidden shaft rotating device and a manufacturing method thereof. Background technique [0002] With the rapid development of science and technology, unmanned driving technology is also developing rapidly. To ensure the safety and reliability of unmanned driving, the most basic requirement is to use various sensors such as lidar, camera or thermal imaging to perceive the surrounding environment of the vehicle to obtain the surrounding road conditions, vehicle attitude and other obstacles. It is convenient to control the steering and speed of the vehicle. Since most sensors can only perceive or detect information in a single direction, various sensors are usually installed on a rotating platform to use the rotating platform to rotate various sensors 360 degrees, so that the sensors installed on the rotating platfor...

AI Technical Summary

Problems solved by technology

[0003] However, the conventional rotating platforms currently on the market are all based on the central axis, so that various sensors can only be installed on the rotating platform around the central axis.

Although there is no problem in using this solution in conventional products, under the development trend of product miniaturization, such as 360-degree scanning lidar used in unmanned vehicles, the central axis of the rotating platform will occupy the center of the rotating platform. The central area separates the limited central area on the rotating platform, which will greatly limit the installation of various sensors, resulting in product size that cannot meet the needs of miniaturization and fail to achieve the desired effect

[0004] In addition, since the central area of ​​the rotating platform is occupied by the central axis, various sensors can only be installed eccentrically on the rotating platform, making the distribution of the moment of inertia of the entire product relative to the central axis uneven. Large jumps or vibrations will occur when rotating, which will seriously affect the normal operation or service life of the rotating platform
