Description
Technical field
This utility model relates to the electronic stairs-mover of a kind of wheelchair, and it can carry wheelchair stair activity easily, and wheelchair originally to climb an animal-drawn seed plough up and down convenient and strength-saving.This stairs-mover also can be carried out on level road except stair activity freely.
Background technology
There is nearly 1,000,000 shank people with disability in China, and they can't normally walk, and normally relies on crutch or wheelchair to realize in the action needs.For many degree of depth shank people with disabilitys, they can't be that media is realized walking with the crutch, and mostly is to replace wheelchair.Existing conventional wheelchair has its advantage naturally, no matter is level land or inclined-plane, and conventional wheelchair can be finished the needs of walking by user basically, and does not need the entourage.For stair, conventional wheelchair can't be up and down.And in China, it is the no elevator building of 5-7 floor that each big city and residents from villages and towns residential building also have considerable part, and this has just influenced conventional wheelchair user's normal trip greatly.Based on this, various stairs-movers have appearred on the market, and it can carry wheelchair stair activity easily.Stairs-mover is realized stair activity by crawler belt, and power is provided by motor.Now the stairs-mover on the market all is earlier wheelchair to be fixed with stairs-mover to stairs-mover with portable, the people is embraced on the wheelchair at last again, does not only loaded down with trivial detailsly like this, also will consume a large amount of muscle power, and need other people to help just can finish.It is heavier to run into wheelchair user's body weight, and perhaps auxiliary's muscle power is small and weak, more difficulty.Resistance was bigger when other deficiency of crawler type stairs-mover was level walking, and it is dumb to move, and crawler belt damages the stair edge easily when stair climbing.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides that a kind of wheelchair is easy for going up and down, the level land also can be used and electric wheelchair stairs-mover simple in structure freely.
The purpose of this utility model is achieved in that the electric wheelchair stairs-mover, comprises the vehicle frame that is installed on the chassis, and the vehicle frame rear end is provided with the wheelchair fixed bar, by bracing frame the wheelchair gripper shoe is installed on the vehicle frame; Two pairs of Athey wheels are installed in the inboard of the front-end and back-end of vehicle frame respectively, the a pair of Athey wheel that is installed in the vehicle frame front end is fixed on the slow-speed shaft two ends and is installed on the vehicle frame by slow-speed shaft, on slow-speed shaft, be provided with gear wheel, gear wheel is meshed with pinion on the engine output shaft, it is characterized in that: but guiding wheelchair guided plate up and down be provided with at the gripper shoe front end in the folding mode, be provided with baffle plate in the gripper shoe rear end.
Be provided with two pairs of auxiliary wheels in the vehicle frame outside, two pairs of auxiliary wheels are between two pairs of Athey wheels.
The vehicle frame rear end upwarps with ground and forms an angle, and it is excessive smoothly between stair and level land that this angle is convenient to stairs-mover.
This utility model is provided with guided plate, the people is sitting on the wheelchair can be directly convenient along guided plate, steadily, stairs-mover up and down like a cork, saved manpower, do not need other people to help.This stairs-mover not only can stair climbing, and utilize auxiliary wheel only need apply a little thrust just can operation freely on level road.
This stairs-mover is simple in structure, humanization designing, and the belt on the Athey wheel is durable in use, and is not easy to wear.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is Fig. 1 vertical view.
The specific embodiment
Referring to Fig. 1 and Fig. 2, this utility model comprises chassis (not marking among the figure), is installed on the vehicle frame 8 on the chassis, and vehicle frame 8 ends are provided with wheelchair fixed bar 1, wheelchair fixed bar 1 meets at right angles with vehicle frame 8, and wheelchair fixed bar 1 is provided with locking device and wheelchair can be lock onto on the fixed bar 1.Vehicle frame 8 tops are equipped with bracing frame 4, and wheelchair gripper shoe 3 is installed on the vehicle frame 8 by bracing frame 4.End in gripper shoe 3 is welded with baffle plate 2 to prevent wheelchair landing before fixing, and the front end of gripper shoe 3 is connected with guiding wheelchair guided plate 7 up and down by bearing pin, and guided plate 7 can and be realized folding around the bearing pin rotation.Two pairs of Athey wheels 5,13 are installed in the front end and the terminal inboard of vehicle frame 8 respectively, the a pair of Athey wheel 5 that is installed in vehicle frame 8 front ends is fixed on slow-speed shaft 12 two ends and is installed on the vehicle frame 8 by slow-speed shaft 12, be provided with gear wheel 10 on slow-speed shaft 12, gear wheel 10 is meshed with pinion 11 on electromotor 14 output shafts.The vehicle frame rear end upwarps the angle that becomes with ground about 35 °, this angle be convenient to stairs-mover between stair and level land smoothly excessively.
Also be provided with 6,15, two pairs of auxiliary wheels 6,15 of two pairs of auxiliary wheels in the outside of vehicle frame 8 between two pairs of Athey wheels 5,13.
The process of this utility model stair climbing is: because the length of vehicle body can cover at least three ladders, so have at least a pair of auxiliary wheel to contact with the stair face, keeping moving stably, make moving that car can be level and smooth on stair.Since behind the car a pair of Athey wheel slightly perk make it can stair pacifically between successfully mutually excessively.On the wheelchair behind the stairs-mover, with the locking of wheelchair and stairs-mover, prevent that wheelchair from sliding by the self-locking device on the fixed bar on stairs-mover.
When this utility model travels on the level land, have only two pairs of auxiliary wheels to contact with ground, crawler belt does not contact with ground, therefore car can move on the level land stably, and do not need motor that power is provided, and just can finish by entourage's hand push, saved power so greatly.
The fixed bar of stairs-mover can fold, can fixed bar is folding forward when not using, can save the placement space of stairs-mover so greatly.
Specific embodiment: car length: about 1.6 meters; Car width: about 0.68 meter; The wheel logarithm: two pairs of auxiliary wheels, diameter 120 millimeter, about 400 millimeter of centre-to-centre spacing between two pairs of auxiliary wheels, two pairs of Athey wheels, a pair of Athey wheel in back become 35 degree angles, Athey wheel diameter 140 millimeter with ground; Centre-to-centre spacing is about about 1.2 meters between two pairs of Athey wheels.Above-mentioned size is not absolute, can be according to deciding on practical situation and application need.The people be sitting on the wheelchair can be directly along guided plate stairs-mover up and down, saved manpower, guided plate links to each other with the gripper shoe that supports wheelchair by pin, but folding; Connecting a baffle plate in the gripper shoe rear end preventing wheelchair landing before fixing, the high 70mm of baffle plate, wide 50mm, thick 8mm, it is connected by the mode of welding with gripper shoe.
Because the rated voltage of motor is 12V, so select the lead-acid accumulator of 12V.Less owing to stairs-mover power in addition, rotating speed requires lower, and requires the motor profile little, so select PX series mini direct-flow deceleration electric motor.
This utility model is simple in structure, be more or less the same with common car, the guided plate that increases can Convenient wheelchair stairs-mover up and down, driving crawler belt by Athey wheel during stair activity realizes, in order to reduce the wearing and tearing of crawler belt, crawler belt does not contact with ground but realizes ground walking by two pairs of auxiliary wheels when moving on the level land.
