Description
Technical field
The present invention relates to a kind of car of riding instead of walk, particularly a kind of crawler-type land-stair dual-purpose scooter that is the tank track moulding.
Background technology
Along with expanding economy and growth in the living standard, most town dwellers move into comfortable multi-storey building apartment because of the improvement of housing condition and live, but this has brought great inconvenience also for limbs permanent disability or other handicapped people's stair activities, causes them can't go downstairs for a long time.In order to allow the people of the wounded or disabled patient of lower limb that lives in multi-storey building or walking inconvenience can be conveniently at level walking, again can own facilitating going upstairs and going downstairs, 97206501.6) and " land-stair dual-purpose scooter " of planet gear type (patent No.: (the patent No.: that the applicant had once designed caterpillar " multifunctional electric stair activity car " 200820229272.9) as climbing the building walking-replacing tool, the former comprises ride instead of walk the structure of car: vehicle frame, seat, cterpillar drive (also claiming the transmission running gear), level road walking (wheel) device (being provided with the linkage that usefulness is raised in the folding and unfolding of level road road wheel), wherein cterpillar drive is formed by two groups of belts that are parallel to each other and as the belt pulley of front and back directive wheel, crawler belt wherein is made up of (triangle) belt, also be provided with and crawler belt is supported localized centre entrust device and transfer, be overlapped on the step by crawler belt during stair activity, stairway step moves in motor power effect lower edge, realizes climbing the building purpose.The shortcoming that the car of riding instead of walk of above-mentioned technology exists has: unreasonable structure, climbing the building after the assembling is short of power, occur impacting staircase phenomenon when causing stair activity easily and can damage ladder, or generation slippage landing dangerous situation, especially turn to difficulty dumb in stair corner, take not steadily, lack the security etc.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, thereby provide a kind of rational in infrastructure, the manufacturing process and assemble is easy, stair activity mobility is good, climbing the building operates steadily and do not have to impact, especially turn to control flexibly in stair corner, the crawler-type land-stair dual-purpose scooter that is the tank track moulding safe and convenient to use.
The present invention constitutes with following technical scheme: it still comprises vehicle frame, seat, the motor of power is provided, power drive mechanism (or claiming driving device) as driving device, by the level road road wheel and be used for the level road running gear that the lifting jack (being the linkage of lifting folding and unfolding level road road wheel) of level road road wheel is formed, be used for the cterpillar drive (or claiming assembly) that stair activity is used, wherein seat is arranged on the vehicle frame top, in the level road running gear, be equipped with road wheel steering mechanism, it is characterized in that: the cterpillar drive that described stair activity is used be by about two groups of sprocket wheel chain wheels that are parallel to each other and install, one independently is installed in the back jockey sprocket of support wheel after the conduct of vehicle frame rear end, be positioned at the vehicle frame front lower place with at least one, promptly near leading to the sprocket wheel back lower place as the support sprocket wheel of preceding support (wheel) and be installed in former and later two jockey sprockets and support on the sprocket wheel and the crawler belt of the wide chain link chain formation that is engaged with is formed, the uniform profile of tooth anti-slip rubber cushion block that is fixed with in outer ring of the crawler belt that constitutes at described wide chain link chain, assembling back its leading to sprocket wheel be inclined upwardly (upwarping) be the structure that is tank formula Track Type to form profile, during stair activity, tank formula crawler belt that the wide chain link chain of car of riding instead of walk constitutes and profile of tooth anti-slip rubber cushion block thereof can link closely and be overlapped on the steps at different levels, stairway step is creeped mobile up and down in motor power effect lower edge, to realize the finishing action of climbing the building up and down smoothly, described power drive mechanism as driving device is to be positioned at a left side near the vehicle frame both sides by independent design respectively, right motor, worm gear and endless screw speed changer, sprocket wheel chain driving member constitutes, and motor power is delivered to all as before (master) power wheel by worm gear and endless screw speed changer and the sprocket wheel chain driving member that sets up separately separately successively, latter two jockey sprocket and preceding the support on the sprocket wheel.
When the present invention made in specific design, its technical characterictic also can further be specially:
One, described former and later two jockey sprockets and before support be equipped with respectively on the wheel shaft of sprocket wheel be used for leading to sprocket wheel, support the sprocket wheel and the back power transmission sprocket wheel of jockey sprocket.
Two, the wide chain link chain of described formation crawler belt can also be the short chain chain replacement with 2--4 row chain.
Three, the electrical contact controller that design on the described seat or on the frame is useful on the control cterpillar drive ride instead of walk with control car the speed of travel, about turn to and advance or retreat.
Four, described seat is oppositely to be installed on the frame, and the purpose that is designed to oppositely to install is to allow the occupant reduce the angle of swing when stair climbing up and down, makes sitting posture more steady and comfortable.
Five, the bottom design at seat has seat angle of inclination actuator, is connected with the chair angle adjusting handle and saves with hand adjustment to make things convenient for the occupant above this angle of inclination actuator.
Six, in described level road running gear, be provided with the level road motor that is used to drive the level road road wheel (with vehicle technology identical).
When using the car of riding instead of walk of the present invention in stair, to creep up and down, owing to be the left and right sides traveling crawler of making tank formula crawler belt appearance structure, outer ring at the wide chain link chain of every group of crawler belt is fixed with the good band profile of tooth rubber cushion blocks of non-skid property, when having stair activity, crawler belt overlap joint ladder is firm, smooth running, safe and reliable, again because of designed left and right sides traveling crawler, its power is by a left side, right motor-driven worm gear and endless screw speed changer and sprocket chain strip transmission mechanism separately provides, having faces a danger when gliding, and self-locking property is good, turn to on-off control left and right sides crawler belt, can when stair activity, keep directly to walking, can form 360 ° of turning efficiencies again, can overcome the difficulty that turns to that causes because of turning, corridor turning is local narrow, can turn to 90 ° of degree even 180 ° of degree on the spot, to finish the conversion walking and the function of creeping between two ladder positions of each floor smoothly.Complete machine has rational in infrastructure, and it is easy to make process and assemble, and stair activity (cat ladder) mobility is good, and smooth running does not have impact, turns to the effect such as convenient flexibly of turning round.
