Abstract
The invention discloses a dual-purpose electric wheelchair capable of going up and down a stair and moving on a flat road, which belongs to the technical field of special equipment for the limb disabled, the old, the weak, the sick and pregnant groups. The dual-purpose electric wheelchair is provided with a seat frame 11 and a back frame mounted on the seat frame. The back frame is provided with a reversing switch 1 for controlling the wheelchair to move forwards or backwards. A battery 9, a motor 10, a speed reducer 8 and a driving chain are arranged in the seat frame. A driving half shaft 25 is arranged below the seat frame. The driving half shaft is provided with a driving chain wheel 19 and an assembled driving wheel body 17. A steering brake 18 is arranged in the wheel body. The assembled driving wheel body consists of 3 to 5 semicircle satellite wheels and 3 to 5 fan-shaped plates 20, and the number can be any one from 3 to 5. When the dual-purpose electric wheelchair goes up and down the stair, the fan-shaped plates are demounted, and the fan-shaped plates are mounted so that the plates form round wheel bodies when the wheelchair moves on the flat road, thus the dual-purpose electric wheelchair can go up and down the stair or move on the flat road smoothly. The dual-purpose electric wheelchair has the characteristics of reasonable structure, easy operation, smooth movement, and safety and reliability.
Description
Technical field
The invention belongs to a kind of small vehicles, but the dual-purpose electric wheelchair of particularly a kind of stair activity and level road walking belongs to lower limb disability and old, weak, sick, pregnant crowd's special equipment technical field.
Background technology
Produced wheelchair for making things convenient for lower limb disability and walking old, weak, sick, pregnant crowd to meet the tendency, domestic existing wheelchair roughly has three kinds: a kind of is the wheelchair that does not have power, carries out by the guardian, also can be walked but be only limited to level road by occupant oneself operation walking; Second kind is electric wheelchair, equally also is only limited to the level road walking; The third is the electric stair climbing wheelchair, uses but also be only limited to stair activity, and level road can not be walked.Many Related products are abroad also arranged, cost an arm and a leg, therefore need to propose a kind of moderate cost, diverse in function, simple in structure, the suitability is strong, performance is better and have stair activity concurrently and dual-purpose electric wheelchair that level road is walked.
Summary of the invention
The objective of the invention is for solve a kind of can help lower limb disability and old, weak, sick, pregnant crowd to realize can free easily stair activity, again can the level road walking to alleviate the dual-purpose electric wheelchair of household's burden.
The objective of the invention is to be achieved through the following technical solutions: but a kind of stair activity and level road walking electric wheelchair, be provided with seat frame, the seat back frame is housed above the seat frame, on the back of the body frame two-direction switch and arm-rest frame are housed, battery main switch, speed adjusting lever, left and right sides power-off brake handle are housed on the arm-rest frame.Accumulator, motor, driving chain, decelerator are housed in the seat frame.Be provided with jack shaft below the seat frame, drive sprocket and combination driving wheel body are housed on the jack shaft, combination drives in the wheel body steering brake is installed, and the seat frame back side is provided with charging socket, and the seat frame front lower place is connected with guard, be provided with stretcher cleat above the guard, the guard front end is connected with bumper, is provided with steering wheel below the guard, simultaneously, as long as combination drives wheel body by simple dismounting fanning strip, can realize the walking of stair activity and level road.
The present invention further improves and implements additional project:
Accumulator is powered to motor by switch, and motor drives decelerator by driving chain, and decelerator rotates combination driving wheel body and jack shaft on the jack shaft by the drive sprocket on the driving chain drive jack shaft together.Described jack shaft is characterized in that: about being each one, all be furnished with independent decelerator and motor, and purpose is as long as the power supply of some motors is cut off, just can realize differential action, realize turning automatically, if need zig zag, only need spur the power-off brake handle again can realize.Described combination drives wheel body, it is characterized in that: combination drives wheel body and is assembled by 3-5 semicircle satellite wheel and 3-5 fanning strip combination and constitute, and fanning strip is provided with alignment pin and links locking plug and link the locking plug hole and be connected.Pull down fanning strip during stair activity, load onto fanning strip during the level road walking and make it become the walking of a circular wheel body realization level road.
Beneficial effect of the present invention: because the present invention adopted accumulator, motor, decelerator to drive, and the principle that is provided with left and right sides semiaxis differential makes its turning, and flexible operation is light.Simultaneously, as long as combination drives wheel body by simple dismounting fanning strip, can realize the walking of stair activity and level road.The characteristics that the present invention has is rational in infrastructure, flexible operation is light, working service is convenient, safe and reliable and cheap.
