The specific embodiment
A kind of accessible automatic creeper truck, long 1220MM, wide 665MM, high 1280MM, comprise crawler attachment 1, chassis 2, buffer unit 3, tilting gearing 4, lowering or hoisting gear 5, seat device 6 and control system 7, it is by Dual-motors Driving, can realize advancing, retreats, turns left, right-hand rotation, stair activity.As Fig. 1, shown in 2, chassis 2 is formed framework 11 by angle steel and is constituted, it is positioned at this utility model integral body bottom, as Fig. 2, shown in 3, crawler attachment 1 is by storage battery 8, a left side, right motor 10, two overlapped independently that walking mechanism is installed in carrier frame 11 both sides about sprocket wheel 9 and crawler belt 12 formed, described sprocket wheel 9 comprises four ratio wheels 14, two drivewheels 16 and four driven pulleys 17, crawler belt 12 is made of chain 15 and the trapezoidal block rubber 13 which is provided with, it is equivalent to the about synchronous band that tooth is all arranged, we understand a tree name, synchronous band on the market and synchronizing wheel price comparison costliness, if adopt synchronous band and synchronizing wheel will improve cost of the present utility model greatly, and the crawler belt 12 tensile strength height that we do, price is low, but quality is big slightly, and itself and contact area of ground are big, steady relatively.Chain 15 and sprocket wheel 9 engaged transmission, about respectively have a motor 10 to drive, motor 10 is by storage battery 8 power supplies, drive drivewheel 16 and driven pulley 17 operations through ratio wheel 14, by turning about the easier realization creeper truck of two motor-driven, thereby reduced drive mechanism, become more easy to control.The aft section of crawler attachment 1 is 45 ° of inclination angles, uses when stair activity, that is to say that this utility model is being down upstairs, just downstairs.As shown in Figure 4 because the creeper truck of our design can only be controlled by people of user, therefore safety, conveniently just become even more important.We have added buffer unit when design, purpose is to play cushioning effect in order to begin with last step at upper and lower stair, because when last last step, when the center of gravity of creeper truck during shortly past the strong point, bigger jolting of amplitude is arranged, creeper truck will fall quickly, and is so very dangerous.Buffer unit 3 comprises bumper bracket 20, damper push rod 18 and support wheel 30, and bumper bracket 20 is provided with damper push rod 18, and bumper bracket 20 rear ends are provided with support wheel 30, and bumper bracket 20 is connected with chassis 2 by spools 31,32 with buffering push rod 18.The effect of buffer unit 3 is to make wheelchair steady when going up downstairs.Owing to added buffer unit, when going downstairs, when front-wheel will arrive first step, the bumper bracket 20 of buffer unit was promoted to rotate by damper push rod 18, and support wheel 30 withstands ground, chassis 2 is lifted consistent with the stair bevel angle, creeper truck is propped up, made the crawler belt plane parallel, jolting when so just having avoided going downstairs with the stair face, play cushioning effect, to reach safe effect.When going downstairs, bumper bracket is regained gradually, goes downstairs simultaneously, and bumper bracket is regained fully when creeper truck is crossed center of gravity, and up to finishing stair down, creeper truck returns to initial condition.When going upstairs,, fall direction upstairs because creeper truck is gone downstairs along direction, and the tailstock portion of creeper truck is 45 ° of inclination angles, so the tailstock portion of the creeper truck step of directly going upstairs, on last last step to a certain degree the time, the buffer unit reverse direction operation, chassis 2 returns to initial condition; Shown in Fig. 4,5, tilting gearing 4 mainly is the inclination when going upstairs, it is realized by tilt stand 36 and inclined lift push rod 19, keep balance in order to ensure seat face when the stair activity and ground, to move after the center of gravity, make its stair activity more steady, more reliable, safer, solved the problem of overturning.Tilting gearing 4 comprises tilt stand 36, inclined lift push rod 19, and inclined lift push rod 19 tops are connected with tilt stand 36 by chute 21, and tilt stand 36 passes through spools 35 and is connected with chassis 2, is provided with snap close 23 between tilt stand 36 bottoms and the chassis 2.When tilting gearing is mainly used in stair activity, make seat and ground keeping parallelism.During stair activity, open snap close 23, start inclined lift push rod 19, tilt stand 36 rotates, and seat turns to parallel to the ground on it.Shown in Fig. 4,5, lowering or hoisting gear 5 can make seat about 600MM that raises, even has exceeded a mediocrity's the height of standing, and the lowering or hoisting gear seat that can raise is in case of necessity conveniently got the thing of eminence.Lowering or hoisting gear 5 comprises folding lifter 22 and inclined lift push rod 19, and inclined lift push rod 19 tops are provided with folding lifter 22, and folding lifter 22 is connected with tilt stand 36 with chute 21 by axle 33.During lifting seat, pin snap close 23, start inclined lift push rod 19, folding lifter 22 opens, and seat raises.As shown in Figure 6, seat unit has backrest layback function, the convenient rest.Seat unit 6 comprises seat 37, backrest 28, pedal 26, connecting rod 27, handrail 25, folding lifter 22 tops are connected seat 37 by axle 34 with chute 29, backrest 28 is connected by connecting rod 27 with pedal 26, and pedal is raise, and makes things convenient for user to have a rest.Pedal 26 can be regulated according to the different users, and seat 37 sides can be placed kettle and suction pipe and be made things convenient for user drinking-water, and the seat side is provided with life plate and can be user and work whenever and wherever possible, learn.As shown in Figure 7, control circuit has manually, radar range finding, buffering, inclined lift control and voice control function, mainly is not too not to be convenient to use the person at some handss, only needs oral account the corresponding command just can realize corresponding action, makes manipulation more convenient.Manual and two kinds of control modes of voice make the control of creeper truck convenient and perfect, and phonological component is directly to be acted on by single-chip microcomputer.Control system 7 comprises control circuit and control lever 24, armrest 25 is provided with control lever 24, described control circuit comprises single-chip microcomputer, drive circuit, radar range finder, microphone and control lever, control lever, radar range finder, microphone connect the single-chip microcomputer input, the single-chip microcomputer outfan connects drive circuit, and drive circuit connects the left and right driving motor and cushions electric pushrod, inclined lift push rod.Manually control is the various functions by control lever control car, and radar range finder is to detect after finishing on the stair, and the control buffer unit is opened, and cushions, and the inclined lift control device is to keep the seat balance when going upstairs.Voice control microphone is under not manual situation, by oral order, realizes controlling of car.
The main function of this car is a stair activity, its concrete scheme is, on falling, along following: utilize the inclined-plane of crawler belt can directly climb up stair when going upstairs, tilting gearing tilts seat simultaneously, make seat face and ground keep balance, when last during to last stair buffer unit open, make crawler belt continue to keep the angle of stair face, up to running to the level land, inclination is regained simultaneously with buffer unit, is converted to the level land pattern.Before first step, will cushion when going downstairs with tilting gearing and open, enter the pattern of going downstairs, and reclaim buffer unit then and go downstairs simultaneously, reclaim tilting gearing, be converted to the level land pattern up to finishing stair down.This utility model mainly is that for convenience the old,weak,sick and disabled waits the user stair activity, has mainly solved the problem that common wheelchair can not stair activity.Go slowly during this utility model stair activity, steadily, cooperate the inclination of seat simultaneously, keep the level of seat, allow user as on the level land, travelling.
