Embodiment Construction

[0010] figure 1 As shown, the specific implementation is as follows:

[0011] A wheelchair includes a lower wheelchair frame 1 and an upper wheelchair frame 7. The lower wheelchair frame 1 is provided with a pedal 2 and a wheelchair walking wheel. This is the prior art and will not be described in detail. The upper wheelchair frame 7 is provided with a seat cushion, The armrests 4 installed on both sides of the seat cushion and the push handles 8 installed on the backrest behind the seat cushion, a locking device is installed on the wheelchair walking wheel to limit the free movement of the wheelchair, and the locking device can adopt any one of the prior art, As long as the rotation of the wheels can be limited, the top of the lower wheelchair frame 7 is fixed with a turntable 3, and the rotating shaft 9 of the turntable 3 is installed on the upper wheelchair frame 7 to drive the upper wheelchair frame 7 to rotate around the turntable 3, and the turntable 3 is provided with a...

Abstract

A wheelchair comprises a lower wheelchair frame and an upper wheelchair frame. A rotating disc is fixed to the top of the lower wheelchair frame, a rotating shaft of the rotating disc is installed on the upper wheelchair frame to drive the upper wheelchair frame to rotate around the rotating disc, a driving wheel and a driven wheel which are meshed with each other are arranged in the rotating disc, the rotating shaft of the rotating disc is driven to rotate through a stepping motor to make the upper wheelchair frame rotate around the rotating disc, and rotation of the upper wheelchair frame is adjusted to make the sitting direction of a user perpendicular to the walking direction of the wheelchair after the user is rotated. According to the wheelchair, by arranging the lower wheelchair frame and the upper wheelchair frame which are in a spilt type, separate rotation of the wheelchair frames can be achieved; as rotation of the upper wheelchair frame is adjusted to make the sitting direction of the user perpendicular to the walking direction of the wheelchair after the user is rotated, sliding of the wheelchair can be limited through friction force between wheelchair wheels and the ground when the user on the wheelchair gets on or off the wheelchair, convenience is brought to single-person operation of the user, and meanwhile the situation that when locking devices fail, the wheelchair slides, and consequently the user bruises can be avoided.

Description

technical field [0001] The invention relates to a walking replacement device, in particular to a wheelchair. Background technique [0002] Wheelchairs are a kind of walking-replacing device often used by people with handicapped legs and feet. For the elderly, due to handicapped legs and feet or lack of physical strength, they need to use wheelchairs instead of walking. It is easy to cause the elderly to fall off the wheelchair and be injured. In the prior art, many wheelchairs use locking devices to limit the movement of the wheels. The locking device will fail due to the load and cause the wheelchair to slide. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing wheelchair is easy to cause the wheelchair to slide when the elderly get on and off the wheelchair, and to provide a wheelchair that limits its sliding by the friction force of the wheelchair itself. [0004] The present invention is for solving the de...
