Description

Automobile seat turntable structure Technical Field The utility model belongs to the technical field of automobile parts, and particularly relates to an automobile seat turntable structure. Background With the continuous increase of the demands of consumers for vehicle versatility and seat flexibility, the rotating function of the car seat becomes an unbiasable factor for satisfying the demands of users. Especially in SUV, MPV/business car, bieke GL8, ideal L9 and new energy, the user's demand for "one-car-multi-purpose" such as carrying things, camping, family going out, business, interactive, is forcing the continuous innovation of car seat development designer and manufacturer to car seat structure. In summary, the positive significance of the rotation of the car seat, especially the third row car seat, is at least that the car seat can be moved on or off more easily, the space flexibility is optimized, the comfort is enhanced, the family and child care are friendly, such as the convenience of feeding infants, the business and multifunctional use is realized, such as the front row of the rotating seat can form a face-to-face space with the rear row, the car seat is suitable for the conversation and interaction of passengers and business negotiations, even entertainment such as chess or playing cards, the safety assistance is realized, and the like. As is known in the art, a toothed disc drive mechanism for driving the rotation of the toothed disc, which is formed by a toothed disc drive motor, a toothed disc drive reduction gearbox or the like, is provided without exception in the construction of a car seat carousel, but because the toothed disc drive mechanism in the prior art rotates with the rotating member, for example when it is arranged on a seat support connection disc as an upper carousel (for the arrangement of a car seat), the toothed disc drive mechanism rotates with rapid rotation of the seat support connection disc. The following fluted disc driving mechanism rotating along with the rotation of the seat supporting connecting disc can expose the defects of increased complexity, incapability of avoiding the winding or intertwining (intertwining) of cables, sensor wires and other components caused by frequent rotation in the working process, adverse stability of an electric system, difficulty in connecting a power supply and a controller even though a fluted disc driving motor rotating along with the seat supporting connecting disc cannot easily occur through a fixed circuit, easiness in occurrence of poor contact or delay or even interruption of signals, influence on precision control, namely relatively harsh requirements on precision control, incapacity of ensuring the stability of the automobile seat in the rotating process due to the fact that the fluted disc driving motor rotates along with the seat supporting connecting disc, insufficient guarantee of safety and durability in a certain procedure, and occurrence of fatigue damage due to frequent rotation of the fluted disc driving motor along with the rotation of the seat supporting connecting disc, although the rotation speed is relatively slow and the centrifugal force is relatively small.
