The end is fixed on the back of the seat, and the state selection switch is fixed on the handle of the seat body.

Preferably, the chair back is provided with an elastic rubber layer; by providing the elastic rubber layer on the chair back, the impact force between the user's back and the chair back can be buffered to ensure safety.

Preferably, protrusions are provided on the elastic rubber layer; by providing protrusions on the elastic rubber layer, not only can the impact force between the user's back and the back of the chair be buffered, but the protrusions can also massage the user's back .

Preferably, the protrusion is a hemispherical protrusion; the hemispherical protrusion can not only massage the user's back, but also increase the user's comfort.

Preferably, the seat is provided with an elastic sponge layer; by arranging the elastic sponge layer on the seat, the impact between the user and the seat can be buffered, increasing the comfort of the user.

Preferably, the thickness of the elastic sponge layer is 5cm-10cm; setting the thickness of the elastic sponge layer to 5cm-10cm can effectively buffer the impact between the user and the seat and save costs.

Preferably, the elastic sponge layer has a thickness of 8 cm; it can effectively buffer the impact between the user and the seat, and save costs.

Preferably, the armrest is provided with an arched armrest; the user can be helped to stand up from the seat by arranging the arched armrest on the handle.

The beneficial effect of the utility model is that, the controller collects the state information of the state selection switch, and the controller makes corresponding control operations on the motor according to the state information of the state selection switch, so as to realize the rotation of the seat around the shaft through the electric push rod. purpose, thereby playing the role of helping; in addition, the utility model has a reliable design principle, a simple structure, and has a very wide application prospect.

It can be seen that, compared with the prior art, the utility model has substantive features and progress, and the beneficial effects of its implementation are also obvious.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following examples are explanations of the utility model, but the utility model is not limited to the following embodiments.

Embodiment one:

As shown in Figures 1 and 2, a lift-up seat provided by the utility model includes a seat body, and the seat body includes a chair back, a seat, an arm handle and chair legs, and a seat for The crossbeam that fixes the chair legs. There is a rotating shaft between the two chair legs in front of the seat body. The rotating shaft passes through the seat to make the seat rotate around the rotating shaft. A lifting device is provided, and the lifting device includes an electric push rod, a motor connected with the electric push rod to drive the electric push rod to expand and contract, a controller connected with the motor and controlling the motion state of the motor, and a state selection connected with the controller switch, the telescopic end of the electric push rod is fixed on the back of the seat, and the state selection switch is fixed on the handle of the seat body.

The state information of the state selection switch is collected by the controller, and the controller makes corresponding control operations on the motor according to the state information of the state selection switch, so as to realize the purpose of driving the seat to rotate around the rotating shaft through the electric push rod, thereby playing a role of helping effect.

In this embodiment, the chair back is provided with an elastic rubber layer; by providing the elastic rubber layer on the chair back, the impact force between the user's back and the chair back can be buffered to ensure safety.

In this embodiment, the elastic rubber layer is provided with protrusions; by arranging protrusions on the elastic rubber layer, not only the impact force between the user's back and the back of the chair can be buffered, but also the protrusions can massage the user's back. effect.

In this embodiment, the protrusion is a hemispherical protrusion; the hemispherical protrusion can not only massage the user's back, but also increase the user's comfort.
