Problems solved by technology

This type of system requires the manipulator to constantly change his center of gravity (leaning forward or backward) to control the two-wheeled robot, especially when going up and downhill. This kind of manipulation method is not suitable for the application of patients and the elderly, and there is a certain degree of danger.

Embodiment Construction

[0017] See attached figure 1 , a two-wheeled wheelchair with a function of adjusting the center of gravity with multiple degrees of freedom, which includes: a seat mechanism 1, wheels 2 and a self-balancing mechanism, and it also includes a counterweight mechanism 17 installed under the seat mechanism 1;

[0018] See attached figure 2 , counterweight mechanism 17 is made up of a plurality of electric push rods 18 and counterweight 19, and a plurality of electric push rods 18 is circumferentially equidistantly arranged, and the end of its push rod is radial outward and is connected with counterweight 19;

[0019] In the initial state, the electric push rods 18 are all in a contracted state. During the movement of the wheelchair, the center of gravity of the wheelchair is changed by controlling the electric push rods 18 to move the counterweight 19 .

[0020] See attached image 3 , in this example, there are six electric push rods 18, they are: rear electric push rod 18-1, l...

Abstract

The invention relates to a wheelchair, in particular to a two-wheeled wheelchair with a gravity center adjusting function. The invention adopts the technical scheme that the two-wheeled wheelchair with the multi-degree-of-freedom gravity center adjusting function comprises a chair mechanism (1), wheels (2), a self-balancing mechanism and balance weight mechanism (17) mounted below the chair mechanism (1), wherein the balance weight mechanism (17) comprises a plurality of electric push rods (18) and balance weights (19); the electric push rods (18) are arranged equidistantly and circumferentially; the tail ends of the electric push rods (18) extend outwards and radially and are connected with the balance weights (19); when the two-wheeled wheelchair is in an initial state, the electric push rods (18) are in a contraction state; in the moving process of two-wheeled wheelchair, the electric push rods (18) are controlled to move balance weights (19) to change the gravity center of the two-wheeled wheelchair. The moving and turning convenience of the two-wheeled wheelchair is increased by adopting the method of increasing the degree of freedom.

Description

technical field [0001] The invention relates to a wheelchair, in particular to a two-wheeled wheelchair with a center of gravity adjustment function. Background technique [0002] As an important environment-friendly rehabilitation tool, the electric wheelchair is an indispensable means of transportation in the daily life of paralyzed patients and the elderly. Wheelchairs with superior performance not only facilitate daily life and improve the quality of life, but also help them regain their ability to work and study, and better integrate into society. Existing electric wheelchairs, such as "an electric wheelchair with adjustable angle" [CN201310252851.0] and "a new type of electric wheelchair" [CN201120148623.5] all adopt the traditional four-wheel structure, occupy a large space, and are difficult to Applied in relatively narrow space. In addition, such as "a reconfigurable wheel-back composite wheelchair" [CN201310165449.9], "a new wheel-track composite electric wheelch...
