Embodiment Construction
[0024] Such as Figure 1~6 As shown, a dual-axis Hall lever manipulator includes a control box 3 with a control rocker on the top, a rocker frame 8 controlled by the control rocker to swing left and right and a rocker frame controlled by the control rocker are arranged in the control box 3 . For the shaft frame 10 that swings back and forth, the control box 3 is also provided with a left and right reset lever mechanism for driving it to reset to the middle position after the rocker frame swings and a front and rear reset lever for driving it to reset to the middle position after the shaft frame swings mechanism; the control box 3 is also equipped with a left and right Hall sensor 4 for sensing the swing direction of the rocker frame and a front and rear Hall sensor 17 for sensing the swing direction of the shaft frame; The definition is based on installing it on the side bracket of the electric wheelchair. The left and right directions correspond to the left and right directio...

The invention relates to a double-shaft Hall lever controller and a working method thereof. The double-shaft Hall lever controller comprises a control box having a control rocker at the top; and a rocker frame controlled by a control rocker to swing left and right and a rotating shaft frame controlled by the control rocker to swing front and back are arranged in the control box. A left-right resetlever mechanism used for driving the rocker frame to reset to the middle position after the rocker frame swings and a front-back reset lever mechanism used for driving the rotating shaft frame to reset to the middle position after the rotating shaft frame swings are further arranged in the control box. A left-right Hall sensor used for sensing the swing direction of the rocker frame and a front-back Hall sensor used for sensing the swing direction of the rotating shaft frame are further installed on the control box. According to the double-shaft Hall lever controller, the left-right reset lever mechanism and the front-back reset lever mechanism for forcing control to reset towards the middle position are additionally arranged, the dangerous situation that a wheelchair cannot be stopped intime due to the fact that an operating lever cannot return to the original state easily is avoided, and the double-shaft Hall lever controller is safe, reliable and good in stability.
Description
technical field [0001] The invention relates to a biaxial Hall lever manipulator and a working method thereof. Background technique [0002] With the progress and development of society, more and more disabled people want to return to society and carry out daily study, work and life. Among them, as an ideal means of transportation, electric wheelchairs have a large market demand and are suitable for the elderly and infirm with lower limb disabilities and inconvenient walking. Compared with manual wheelchairs, they have a larger range of motion, more suitable people, and powerful functions. [0003] As the main component of the smart electric wheelchair, the controller is the most direct part for the disabled to control the electric wheelchair. By controlling the manipulator, the user expresses the operation intention and realizes the control of the driving speed and direction of the electric wheelchair, so manipulating the controller is very important for the operation of t...
