Embodiment Construction

[0033] see Figure 1 to Figure 9 , the figure shows a single motor driving the backrest to rotate independently and drive the backrest and seat cushion to rotate synchronously.

[0034] The base 100 is a disc, which can be directly installed on the vehicle floor (not shown in the figure), or can be installed on a pair of slide rails (not shown in the figure).

[0035] The lower part of the backrest frame 200 is a cylindrical body 210, and the middle and upper part is a backrest body 220. A flange part 213 is arranged at the bottom of the cylindrical body 210, and the flange part 213 passes through a backrest rotating pressure plate 230 pressed against the flange part 213. And the fastening bolt 240 is rotatably installed on the base 100 ; a wear-resistant gasket 700 is provided between the flange part 213 and the base 100 .

[0036] The ring gear 250 is provided on the inner peripheral surface 212 of the cylindrical body 210 .

[0037] The motor 400 is installed on the base ...

Abstract

The invention discloses a single motor driving the backrest to rotate independently and to drive the backrest and seat cushion to rotate synchronously. Install the motor on the base, the output shaft of the motor is provided with a drive gear, the drive gear meshes with the ring gear; the electromagnetic clutch mechanism is arranged between the cushion skeleton and the backrest skeleton, and the electromagnetic clutch mechanism needs the backrest skeleton to rotate separately. The back frame is separated from the cushion frame, and the back frame and the cushion frame are connected when the back frame and the seat frame need to be rotated together. The invention adopts one motor to separately drive the seat back to rotate or the seat back and the seat cushion to rotate together according to needs, which solves the problem of insufficient space for multi-motor arrangement in the existing seat and realizes the requirement of light weight of the seat by reducing the number of motors.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a single motor that drives the backrest to rotate independently and drives the backrest and seat cushion to rotate synchronously. 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 independently rotated ...
