Electric rotating and sliding mechanism for a child safety seat

Abstract

Electric rotating and sliding mechanism for a child safety seat An electric rotating and sliding mechanism for a child safety seat, comprising a first worm and a gear disc. The first worm is located inside the seat base (1) and engages with the gear disc, the first worm drives the gear disc to rotate when rotating, allowing infinite adjustment of the rotation angle, and realizes locking after the adjustment is stopped. The gear disc is arranged in an inclined manner relative to the first worm, thanks to this inclined design, there is no mutual compression pressure between the gear disc and the first worm, thus reducing the engagement pressure at the connection point and, therefore, minimizing wear.

Title of the invention: Electric rotating and sliding mechanism for a child safety seat Technical field

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

[0002] The child safety seat is installed on the passenger car and fixed to the rear seat to protect the safety of the baby while driving the vehicle. Generally, child safety seats are divided into baby safety seats and child safety seats. From the perspective of the use method, they are generally divided into two types: lying and sitting. The correct use of the child safety seat can effectively reduce the mortality rate of children in car accidents by 70%.

[0003] Existing child safety seats generally use a fixing structure to adjust the rotation angle. After adjusting to the appropriate angle, the adjusted angle is locked by a locking structure. This angle adjustment method is limited and will be affected by the preset angle of the adjustment structure, which does not allow infinite adjustment. For this, we propose an electric rotation and sliding mechanism for the child safety seat. Content of the invention
