Manual and electric integrated rotating disc for automobile seat and rotating method of manual and electric integrated rotating disc

Abstract

The invention relates to a manual and electric integrated rotating disc for an automobile seat and a rotating method of the manual and electric integrated rotating disc. The integrated rotating disc comprises a chassis, a rotating disc body, a pressing disc, an upper holder and a lower holder and further comprises one of an electric driving device and a manual driving device, the pressing disc is fixedly connected with the chassis, and the pressing disc is used for pressing the rotating disc body on the chassis; the rotating disc body and the chassis are in rotating fit through the lower holder, and the rotating disc body and the pressing disc are in rotating fit through the upper holder; and the electric driving device or the manual driving device is connected with the chassis and the rotating disc body and is used for driving the rotating disc body to rotate relative to the chassis. When the integrated rotating disc is used as an electric rotating disc, an electric driving device is selected to be installed, when the integrated rotating disc is used as a manual rotating disc, a manual driving device is selected to be installed, the manual and electric universality is good, and modification between manual operation and electric operation can be achieved through slight modification.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a manual electric integrated turntable for a car seat and a rotating method thereof. Background technique [0002] The car seat turntable refers to the turntable installed under the seat cushion in the car seat. The turntable is used to adjust the rotating seat, which can make the seat rotate 360°. The car seat with the turntable is used in today's luxury cars or commercial vehicles. The application requirements in the car are getting higher and higher. On the one hand, the seat can be rotated and adjusted to welcome and face the guests. On the other hand, the front row personnel can turn to the rear row to facilitate communication with the rear row personnel.

AI Technical Summary

Problems solved by technology

[0003]At present, car seat turntables are divided into electric turntables and manual turntables. The existing manual turntable technology is relatively mature, while the electric turntable technology is not mature enough. If the electric turntable with immature technology is applied to the car seat, there will be the following risks: if the electric turntable rotates for no reason, it will lead to unsafe factors, which will harm the driver or passengers. Personal safety poses a threat, so the current research and production of electric turntables are urgently needed

For example, the patent application whose publication number is CN110626231A: Car Seat and Electric Seat Rotating Mechanism discloses an electric seat rotating mechanism, which includes a base, a turntable connected in rotation with the base, and a turntable The driving device and the locking device used to lock the turntable and the base, the turntable driving device is electric drive, the locking device is manual locking, remove the turntable driving device, and use the locking device to make the seat rotation mechanism manual The seat rotation mechanism realizes the common use of the electric seat rotation mechanism and the manual seat rotation mechanism, and reduces the types of spare parts, but there are still the following disadvantages: (1) When used as an electric seat rotation mechanism, a turntable drive device must be installed And the locking device, using the locking device to prevent rotation and shaking, this undoubtedly increases the structural complexity and production cost of the seat rotation mechanism, and the practicability is poor, and the versatility of the seat rotation mechanism in both electric drive and manual drive is not enough Perfect; (2) The pressure plate is located in the inner ring of the turntable, which has the disadvantage of small pressing area. The installation point of the turntable is on the outer ring, and the point of force is also on the outer ring. The turntable is easily pulled out from the pressure plate, making The anti-peeling effect of the turntable is poor. In order to prevent the turntable from falling off the base, the upper and lower anti-detachment hooks are welded on the turntable and the base respectively in this patent, which increases the complexity of the turntable structure and production cost; (3) in the turntable drive device The meshing transmission of the gear and the ring gear is used, but there is no expansion structure, and the meshing gap between the gear and the ring gear is too large or too small, and the shortcomings are unstable.
