Abstract
The invention relates to an engine driven wheelchair capable of climbing stairs. In the invention, a seat frame gets power from a direct current motor to drive travelling wheels or climbing wheels arranged at the lower face of the seat frame so as to realizing the function of travelling or climbing the stairs. When the engine driven wheelchair is used by the lower limb disabled, the effects of climbing the stairs up and down, going forward and backward and turning from side to side on ground floor can be realized only by operating handles and buttons without help of other people. The engine driven wheelchair is a device for assisting the disabled for living.
Description
Technical field:
The present invention is the equipment that transports patient or make things convenient for patient.
Technical background:
Do not find like product on the current domestic market.
Summary of the invention:
The present invention is assembled and is constituted by seat, power set, running gear, climbing device based on vehicle frame.
Seat of the present invention is provided with self-level(l)ing device.Seat hangs and to be articulated on the vehicle frame, and when vehicle frame tilted forward and back, the seat that suspension is articulated on the vehicle frame was subjected to gravity effect, can adjust automatically, remains default and angle horizontal plane.
The present invention is provided with resistance shake device.Antivibrator is provided in a side of the opposite pressure cylinder of the free-ended both direction of seat, and antivibrator is by the control of resistance shake controller.Resistance shake controller is the forked type structure, and respectively there is power contact both sides.One plummet body is arranged between the contact, both sides, and the upper end is articulated in fork body upper end, and the lower end is by two resistance shake spring yoke body lower ends.When vehicle frame tilted forward and back, the plummet body touched the power contact of a side, sends instruction current, opened the pressure cylinder valve of a corresponding side, pressure is situated between injects, and restored up to seat, and the plummet body is parallel with the fork body, dump, and leveling finishes.Resistance shake spring can stop the plummet body to touch power contact during little shake.Can make the default angle of seat maintenance and horizontal plane and steady like this.
Climbing mechanism of the present invention adopts four-wheel drive.Lifting on demand.The climbing wheel is " monolateral star spoke " structure, 1. (sees accompanying drawing) at total axle sleeve and goes up 2. three to five of uniform radial disc, monolateral support.Walk star-wheel split axle 3. 4. an end be fixed on the spoke plate end, the other end does not support disc, have to poise.There is friction board 5. in the planetary gear outside.Pressure cylinder is attached on the hollow line shaft of two climbing wheels.6. pressure cylinder can clamp all planetary gears of braking by the lever on hollow line shaft inside connecting rod and disc next door.
Four climbing wheels all have auto-lock function (pinning when not being the climbing end).Promptly be only when rotating driveshaft, to climb wheel could rotate.Directly the moving climbing wheel of dish can not rotate.
Walking mechanism of the present invention is that the climbing wheel lock is set above the climbing line shaft, and the planetary gear that the below is provided with walking friction clutch driving-disc and climbing wheel constitutes.The climbing lock stretched out lock pin and pins the climbing spoke plate when disc that finishes the climbing wheel when climbing rotated to the default angle of horizontal plane.Meanwhile, walking friction clutch driving-disc is combined by zygote with the planetary gear that lands, and can walk.The wheel lock can pin any one disc.Driving-disc can with any one planetary gear combination of landing.
Embodiment:
Vehicle frame of the present invention is the cuboid framework, and one is point articulated on the seat center of gravity line behind central upper portion position and the passenger.At vehicle frame top front end (handrail just) dress handle.Left hand can be inclined to former and later two positions for the climbing handle, promptly " on " D score, the right hand is the directional lever of walking, can tilt by " preceding " " back " " left side " " right side " four direction.Be the walking switch around the handle.After selected direction, to press under the palm little finger of toe side, car just has action, and that presses is dark just fast, otherwise slow.Elbow rear portion, left and right sides dress braking backup plate.
In four jiaos of distal-most end of vehicle frame train is set.When left handle point to " on " time, trailing wheel descends, and makes vehicle frame become the level of approximation state; When handle pointed to D score, front-wheel descended, and made vehicle frame journey level of approximation state.Climb building end handle and return zero, low wheel restores and locks, and planetary gear lands and can walk.
The present invention's direct current generator is a power, also will constantly replenish energy storage equipment with air pressure or hydraulic pump, makes it keep certain pressure from start to finish, to assisted control at any time.
