Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.

As shown in fig. 1-4 together, the present invention provides a seat with an auxiliary sitting-up function, comprising two longitudinal supporting housings 7 oppositely disposed, wherein a base 4 is disposed at the bottom end side of the longitudinal supporting housing 7, a rotatable seat cushion 2 is disposed at the top end side of the longitudinal supporting housing 7, and the seat cushion 2 and the base 4 are disposed at the same side of the longitudinal supporting housing 7; the top end of the longitudinal support shell 7 is provided with a handrail 6.

The base 4 is fixedly connected with a longitudinal support housing 7.

The cushion 2 is supported by the cushion supports 3 on both sides, and the cushion 2 and the cushion supports 3 rotate synchronously.

One end of the cushion bracket 3 is arranged in the longitudinal supporting shell 7, and the cushion bracket 3 is connected with the longitudinal supporting shell 7 through a rotating shaft 13.

The pivot 13 wears to establish in the main part of cushion support 3, and the both ends rigid coupling of pivot 13 is in vertical support casing 7, and cushion support 3 can follow pivot 13 rotatory certain angle.

The cushion bracket 3 rotates through the matching of the connecting rod 12, the transmission gear 9 and the motor 10.

One end of the cushion bracket 3 positioned in the longitudinal support shell 7 is hinged with one end of a connecting rod 12 through a second hinged shaft 11; the other end of the connecting rod 12 is hinged with the top end of the transmission gear 9 through a first hinge shaft 8.

The connecting rod 12 and the driving gear 9 are movably mounted in the longitudinal support housing 7, the driving gear 9 only allowing up and down movement.

The gear of assembly meshes on 9 and the motor 10 output shaft of driving gear, and the motor 10 realizes the lift of driving gear 9 through the meshing of gear, and driving gear 9 realizes cushion support 3 and cushion 2 along the rotation of pivot 13 through cooperating with connecting rod 12 at the lift in-process.

The motor 10 is fixedly arranged in the longitudinal supporting shell 7, and the motor 10 is a forward and reverse motor and can rotate forward and reverse.

One side of the handrail 6, which is close to the cushion 2, is provided with a free end, and the free end is sleeved with a rubber protective sleeve 1.
