Abstract

The invention discloses an electrically powered wheel chair steering control mechanism. The electrically powered wheel chair steering control mechanism is characterized by mainly comprising a rack, a steering drive device, a first center branch chain, a second center chain and a steering wheel. The steering drive device is fixed on the rack. The center of the first center branch chain is connected with the rack in a hinge joint mode. One end of the first center branch chain is connected with the steering drive device, and the other end of the first center branch chain is connected with the second center branch chain. The second center branch chain is connected with the steering wheel. The steering wheel is connected with the rack in a hinge joint mode. The steering drive device is composed of a screw rod rear bearing, a screw rod, a screw rod front bearing, a coupling, a front bearing seat, a motor with a reducer, a screw nut and a back bearing seat. The first center branch chain comprises an upper connecting plate, a sliding block, a lower connecting plate and a pin. The second center branch chain is a parallelogram mechanism composed of a main connecting rod and two auxiliary connecting rods. The steering wheel is composed of a steering wheel support and a steering wheel body. The electrically powered wheel chair steering control mechanism has the advantages of being accurate in controlling, smooth in operation, compact in structure, simple to operate, and low in cost.

Description

technical field [0001] The invention belongs to auxiliary appliances for disabled persons, in particular to an electric wheelchair steering control mechanism. technical background [0002] According to incomplete statistics, in 2006 there were about 82.96 million people with various disabilities in my country, accounting for 6.34% of the total population of the country. There are a large number of elderly and disabled people with inconvenient lower limbs in today's society, which makes the design of handicapped tools for the purpose of improving their quality of life increasingly important. Electric wheelchairs are good auxiliary tools for people with disabilities in the lower limbs to travel, and they are necessary equipment to improve their freedom of movement and enable them to better integrate into the lives of healthy people. Due to the limited space, small size and certain speed of the electric wheelchair, the requirements for steering control during the exercise of t...
