[0002] Most of the wheelchairs with stair-climbing function on the market now realize the stair-climbing function through crawler devices or planetary gear devices. The reliability of these two devices is not high, mainly because wheelchairs may slip on steep stairs. Accidents such as rollover, for the disabled, the above-mentioned accidents are all more dangerous, so there is an urgent need for a wheelchair that can safely climb stairs

The invention provides a wheelchair capable of climbing stairs. The wheelchair capable of climbing stairs comprises a wheelchair frame, wheels, back safety air bags, a back supporting electric actuator, a rotating joint A, a top supporting frame, a rotating joint B, telescopic units and a rotating joint C. The wheelchair is characterized in that four supporting legs are arranged on the lower portion of the wheelchair frame, one wheel is installed under each supporting leg, a backrest plate is arranged on the rear portion of the wheelchair frame, the rotating joint A is arranged on the upper portion of the backrest plate, a rotating shaft of the rotating joint A is fixedly connected with the upper end of the back supporting electric actuator, a rectangular flat plate is arranged at the lower end of a telescopic rod of the back supporting electric actuator, and two back safety air bags are arranged at the two sides of the backrest plate. By expanding all the telescopic units, square plates at the upper and lower ends jack the roof and the ground respectively, and the wheelchair and a user can be pulled on the floor safely.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a wheelchair for climbing stairs. Background technique [0002] Most of the wheelchairs with stair-climbing function on the market now realize the stair-climbing function through crawler devices or planetary gear devices. The reliability of these two devices is not high, mainly because wheelchairs may slip on steep stairs. Accidents such as rollover, for the disabled, the above-mentioned accidents are all more dangerous, so there is an urgent need for a wheelchair that can safely climb stairs. Contents of the invention [0003] In view of the above problems, the present invention provides a wheelchair for climbing stairs. The present invention expands each telescopic unit so that the square plates at the upper and lower ends respectively withstand the roof and the ground, so that the wheelchair and people can be safely pulled upstairs; The ultrasonic range finder detec...
