AI Technical Summary

Technical Problem

Existing electric drive mechanisms for child car seat angle adjustment are lengthier and occupy more space, making installation difficult due to the straight-line connection between the motor's output shaft and the screw rod.

Method used

An electric angle adjustment device with a motor, rotating member, and intermediate transmission assembly, where the motor's output shaft intersects with the rotating member, allowing the seat body to slide relative to the base, reducing overall length and space occupation.

Benefits of technology

The device efficiently adjusts the seat angle while occupying less space, ensuring smooth and compact installation and operation.

Abstract

The present invention also discloses an electric angle adjustment device disposed between a seat body and a base of a child seat, the seat body being assembled to be slidable in the front-rear direction of the base, and the angle of the seat body relative to the base being adjusted during the sliding process, the device including a motor, a rotating member, a sliding member, and an intermediate transmission assembly, the rotating member extending in the sliding direction of the seat body, the motor being arranged on one of the seat body and the base, the output shaft of the motor extending in the left-right direction or the up-down direction of the base so as to intersect with the rotating member, the sliding member assembled on the other of the seat body and the base and slidable on the rotating member, the intermediate transmission assembly being assembled on the output shaft of the motor and the rotating member, the motor rotatively drives the rotating member via the intermediate transmission assembly, the sliding member sliding on the rotating member by the rotation of the rotating member, and the angle of the seat body relative to the base is electrically adjusted, thereby occupying a small space and having a short overall length.
