Title:
ELECTRIC CABLE DRIVE MECHANISM HAVING SELF-RETURN CAPABILITY
Document Type and Number:
WIPO Patent Application WO/2022/268010
Kind Code:
A1
Abstract:
An electric cable drive mechanism having self-return capability, comprising a housing assembly (1), a motor (2), a three-stage transmission mechanism (3) and a multifunctional nut (4). The three-stage transmission mechanism (3) comprises a coil spring assembly (32). The motor (2) is fixed to the housing assembly (1). The three-stage transmission mechanism (3) and the multifunctional nut (4) are mounted in the housing assembly (1). The multifunctional nut (4) comprises two cable mounting grooves (41) and is in transmission connection with the motor (2) by means of the three-stage transmission mechanism (3). The electric cable drive mechanism having the self-return function uses a three-stage transmission system, which outputs a force larger than a two-stage transmission system. A split-type multifunctional lead screw is easy to install, is not scratched during the installation of the coil spring in the assembly process, and solves the problem of abnormal sounds generated in the coil spring installation process.
