Description

electric booster chair

technical field

The invention relates to a chair, in particular to an electric power-assisted chair that can help people who have difficulty standing up and sitting down.

Background technique

The elderly or the weak and disabled have certain difficulties in getting up and sitting, which brings a lot of inconvenience to life. Most of the booster chairs currently on the market can only move the seat alone to provide the user with standing power, and are not easy to operate. Considering the characteristics of people with mobility difficulties, the present invention adopts the method of simultaneous movement of the backrest and the seat cushion, which expands the assisting range of the booster chair, and uses an electric push rod and a wireless remote control to bring great convenience to use.

Contents of the invention

In order to overcome the deficiency that existing power-assisted chairs cannot effectively assist people with mobility difficulties to stand up or sit down, the present invention provides an electric power-assisted chair that can effectively assist people with mobility difficulties to stand up or sit down.

The technical solution adopted by the present invention to solve its technical problems is:

An electric booster chair, comprising a structural support, a seat, a backrest and armrests, the armrests are installed on both sides of the seat, the backrest is located at the rear of the seat, and the seat and the backrest are located on the structural support On the seat, the booster chair also includes an electric push rod, the action end of the electric push rod is installed on the back of the back, the lower end of the back is hinged to the rear of the seat, and the front of the seat is connected to the back of the seat. The structural support is hinged, and the lower part of the structural support is provided with a horizontal guide rail, and the base of the electric push rod is mounted on the horizontal guide rail so that it can slide left and right.

Further, a wireless remote controller is installed on the armrest, and the wireless remote controller is linked with the activation switch of the electric push rod. Of course, you can also choose to install it in another location; or use a wired switch.

Still further, the lower end of the backrest is connected to the rear part of the seat, and the front part of the seat is connected to the structural support through bearings.

Furthermore, the base of the electric push rod is installed on the horizontal guide rail through the anti-friction assembly.

The beneficial effects of the present invention are mainly manifested in: 1. The booster chair has a simple structure, and the backrest remains vertical throughout the entire exercise process, which provides great help for standing and sitting down and improves the comfort of the chair; 2. The movement of the chair is controlled by a wireless remote control, which is more convenient and improves safety.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

Referring to Figures 1 to 4, an electric booster chair includes a structural support 17, a seat 16, a backrest 11 and armrests 15, the armrests 15 are installed on both sides of the seat 16, and the backrest 11 is located on the seat 16 The rear side of the seat 16 and the backrest 11 are located on the structural support 17, and the booster chair also includes an electric push rod 12, and the action end of the electric push rod 12 is installed at the rear of the backrest 11. The lower end of the backrest 11 is hinged with the rear part of the seat 16, the front part of the seat 16 is hinged with the structural support 17, the bottom of the structural support 17 is provided with a horizontal guide rail 13, and the electric push rod 12 The base can be slidably installed on the horizontal guide rail 13 left and right.

Further, a wireless remote controller 14 is installed on the armrest 11 , and the wireless remote controller 14 is linked with the activation switch of the electric push rod 12 . Of course, you can also choose to install it in another location; or use a wired switch.

Still further, the lower end of the backrest 11 is connected to the rear of the seat 16 , and the front of the seat 16 to the structural support 17 is connected by bearings.

Furthermore, the base of the electric push rod 12 is installed on the horizontal guide rail through the anti-friction assembly.

In this embodiment, the wireless remote controller is installed on the armrest, which can control the rise and fall of the electric push rod and can control the running speed of the electric push rod; Remind the user to stand up or sit down, and when an emergency occurs, the alarm button on the remote control can be pressed to give an alarm so as to get rescue in time. When a person needs to stand, press the remote control to select the standing speed, the electric push rod pushes the backrest upwards, and at the same time the electric push rod slides on the guide rail, the backrest drives the seat to turn upwards so that the human body can reach the standing state; Press the button on the remote control to select the sitting speed, and the electric push rod will fall and move in the opposite direction on the guide rail to restore the seat, so that the human body will change from standing to sitting.

The connection between the backrest and the seat, and between the seat and the structural support can be realized through bearing connection. The shape of the guide rail can be realized by other shapes or structures. The number of electric push rods can be added or the installation position can be changed to increase the thrust. A transmission device can be added to facilitate the sliding of the electric push rod on the guide rail. It is possible to change the installation position of the wireless remote control or increase its functions.
