Problems solved by technology

[0002] As a means of travel, wheelchairs can provide convenience for the elderly and people with inconvenient legs and feet. However, the road surface is generally not a single plane, and there are slopes in many places, such as roads and houses. When driving up and downhill, people and wheelchairs are prone to leaning forward or backward, which affects the comfort of people on the one hand, and on the other hand, there is a very big safety hazard, especially for the elderly.
[0003] In the case of uphill, downhill, and sideways inclination, if the wheelchair travels too fast, turns too fast, or brakes too fast, it is easy to cause serious accidents such as wheelchair rollover, forward flip, and rear flip.
[0004] Due to factors such as the power of the wheelchair motor and the maximum safe inclination angle of the structural chassis design, when the maximum safe angle is exceeded, it is easy to cause the wheelchair to overturn, the motor is damaged, and further lead to serious safety accidents

Abstract

The invention relates to a system for road surface slope detection and automatic adjustment of a wheelchair. The system comprises a wheelchair body and a control system, and is characterized in that the wheelchair body comprises a fixing frame, front wheels, rear wheels, a seat back, a foot pedal, hydraulic rods and damping spring supporting rods, and the control system comprises a motor, a hydraulic pump, a storage battery, a controller box and a front wheel drive motor; and the controller box is internally provided with a gyroscope, an accelerometer sensor and a controller main board. The system for road surface slope detection and automatic adjustment of the wheelchair mainly realizes that 1, through an accelerometer, the gyroscope detects the heeling condition of a road surface on which the wheelchair travels; 2, the wheelchair is automatically adjusted to be level according to the detected road surface condition to improve the comfort and safety of the ride; 3, according to the safety envelope of the wheelchair and the slope condition of the road surface, the traveling speed and the turning speed of the wheelchair are automatically adjusted; 4, when a slope exceeds the safe power of the wheelchair motor, the wheelchair is automatically stopped, the motor is protected, and a safety accident is avoided; and 5, through a speaker arranged in the wheelchair, the status of the wheelchair is automatically broadcasted to assist a user in driving.

Description

technical field [0001] The invention relates to the technical field of intelligent wheelchairs, in particular to a system for detecting road slopes and automatically adjusting balance, driving speed, turning speed and maximum climbing gradient of wheelchairs. Background technique [0002] As a means of travel, wheelchairs can provide convenience for the elderly and people with inconvenient legs and feet. However, the road surface is generally not a single plane, and there are slopes in many places, such as roads and houses. When driving up and downhill, people and wheelchairs are prone to leaning forward or backward, which affects the comfort of people on the one hand, and on the other hand, there is a very big safety hazard, especially for the elderly. . [0003] In the case of uphill, downhill, and sideways inclination, excessive driving speed, excessive turning speed, and excessive braking speed of the wheelchair can easily lead to serious accidents such as wheelchair ro...
