Seat capable of driving backrest to independently rotate and driving backrest and seat cushion to rotate synchronously through single motor

Abstract

The invention discloses a seat capable of driving a backrest to independently rotate and driving the backrest and a seat cushion to rotate synchronously through a single motor. The seat comprises: a base, a backrest framework and a seat cushion framework, a motor and an electromagnetic clutching mechanism, wherein the backrest framework and the seat cushion framework are rotatably mounted on the base; an inner gear ring is arranged on the backrest framework; the motor is mounted on the base; an output shaft of the motor is provided with a driving gear; the driving gear is engaged with the inner gear ring; the electromagnetic clutching mechanism is arranged between the seat cushion framework and the backrest framework; the electromagnetic clutching mechanism can be used for separating the backrest framework and the seat cushion framework when only the backrest framework is needed to rotate, and connecting the backrest framework and the seat cushion framework when the backrest framework and the seat cushion framework need to rotate together. By adopting one motor, the backrest can be driven to rotate independently or the backrest and the seat cushion can be driven to rotate together respectively according to requirements; the problem of an existing seat that a plurality of motors are arranged and an arrangement space is not enough is solved; the quantity of the motors is reduced so that the lightweight requirements of the seat is realized.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a seat in which a single motor drives the backrest to rotate independently and drives the backrest to rotate synchronously with the seat cushion. Background technique [0002] The current seat drive is generally driven by one motor and one mechanism; in a functionally integrated seat, because of the increase in functions, the number of motors required increases, and the demand for seat space will also be large. In order to meet the development of unmanned vehicles, in order to realize the convenience of communication between the main driver and the co-driver, and between the front row and the rear passenger, the rotation of the seat has become a requirement; the current communication seat is usually a cushion The backrest rotates integrally, taking the main driver and the co-driver as an example, when the main driver and the co-driver need to communicate, the backrest can be indepe...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a seat with a single motor driving the backrest to rotate independently and drive the backrest cushion to rotate synchronously in order to solve the existing seat multi-motor arrangement. The problem of insufficient space and by reducing the number of motors, the requirement of light weight of the seat can be realized
