Electric rotation and sliding mechanism for a child safety seat

Abstract

Electric Rotation and Sliding Mechanism for a Child Safety Seat. The invention relates to an electric rotation and sliding mechanism for a child safety seat, comprising a first worm gear and a gear disc. The first worm gear is located inside the seat base (1) and engages with the gear disc. The first worm gear drives the rotation of the gear disc, allowing infinite adjustment of the rotation angle, and locks the mechanism once the adjustment is complete. The gear disc is inclined relative to the first worm gear. Thanks to this inclined design, there is no mutual compressive pressure between the gear disc and the first worm gear, thus reducing the engagement pressure at the connection point and, consequently, minimizing wear.

Title of the invention: Electric rotation and sliding mechanism for a child safety seat technical field

[0001] The present invention belongs to the technical field of safety seats, and relates more particularly to an electric rotation and sliding mechanism for a child safety seat. Previous technique

[0002] The child safety seat is installed in the passenger car and secured to the rear seat to protect the baby's safety while the vehicle is in motion. Generally, child safety seats are divided into infant safety seats and child safety seats. In terms of how they are used, they are usually divided into two types: reclining and upright. The correct use of a child safety seat can effectively reduce the child fatality rate in car accidents by 70%.

[0003] Existing child safety seats generally use a fixing structure to adjust the rotation angle. After adjustment to the appropriate angle, the adjusted angle is locked by a locking structure. This method of angle adjustment is limited and will be affected by the predefined angle of the adjustment structure, thus not allowing for infinite adjustment. Therefore, we propose an electric rotation and sliding mechanism for the child safety seat. Contents of the invention

[0027] The gear disc 31 is arranged at an angle relative to the first worm 34; thanks to the inclined design, the gear disc 31 and the first worm 34 will not compress each other, thus reducing the engagement pressure at the point of connection and further reducing wear.

[0028] The rotating component 3 also includes several sets of positioning plates 33, several sets of positioning plates 33 are arranged symmetrically on the seat base 1, forming a space for the placement of the safety seat connection seat 2, the lower outer edge of the safety seat connection seat 2 is designed in the shape of a ring, the safety seat connection seat 2 is hooked by the ring-shaped outer edge inside several sets of positioning plates 33, after being driven by the rotating metal disc 32, the safety seat connection seat 2 will rotate in the space limited by the positioning plates 33.
