AI Technical Summary

Technical Problem

Existing linear drive mechanisms struggle to meet the combined performance requirements of high power density, high operational reliability, and ultra-low noise levels in extremely confined spaces such as vehicle seats. Traditional solutions sacrifice load-bearing efficiency and rigidity in pursuit of compactness, while structural reinforcement leads to increased volume and weight. Furthermore, noise reduction design affects transmission response speed and power density.

Method used

It adopts a compact reciprocating kneading transmission mechanism. Through the innovative layout design of the main drive mechanism, steering transmission component, first output mechanism and second output mechanism, it utilizes the vertical arrangement and coaxial fixed connection of the drive worm and the main drive shaft, the staggered shaft helical gear pair and the one-piece molded housing partition to achieve efficient, reliable and quiet transmission.

Benefits of technology

It achieves efficient, reliable, and quiet transmission in extremely limited spaces, significantly improving the compactness, strength, and low noise of the transmission mechanism, and meeting the comprehensive performance requirements of harsh environments such as vehicle seats.

Abstract

This invention discloses a compact reciprocating kneading transmission mechanism, including a mounting box, a main drive mechanism, a first output mechanism, and a second output mechanism. The main drive mechanism comprises a motor, a drive worm gear, and a main drive shaft connected via a steering transmission component. The drive worm gear is spatially perpendicular to the main drive shaft, and the axis of the main drive shaft is innovatively configured to extend along the maximum diagonal direction of the internal space of the mounting box, thereby achieving maximum effective length within a limited volume and realizing extreme compactness. The main drive shaft simultaneously drives the first and second output mechanisms, which output rotational motion with different reduction ratios through different transmission paths. This invention comprehensively achieves minimization of volume, improved operational reliability, and noise suppression through optimized three-dimensional spatial layout, a highly integrated unibody structure, and the selection of low-noise transmission pairs.
