[specific embodiment]
The utility model is described in further detail below in conjunction with accompanying drawing.
Extremely shown in Figure 5 as Fig. 1, of the present utility model folding as follows: folding with expansion process, shut forward-reverse switch 49 and pull up attaching plug 19 proposition power supply boxs 20, press seat folder fin 16 folding backs 13 handrails 14, unclamping turning rack adjusting handle 6 makes steering handle 9 be in free state, pull and connect the connection pin hole that pin handle 34 makes connection pin disengaging after poppet 18, the transverse tube 34 of mentioning on the pedal support 2 makes vehicle frame folding, connection pin hole on the turning rack 1, aim at the connection pin of the transverse tube 34 on the pedal support 2, make connect pin pass this hole fixedly turning rack 1 locking turning rack adjusting handle 6 make turning rack 1 fastening.The folding latch hook 21 of after poppet 18 is aimed at latch hook fastening under the seat cushion.Launch: open folding latch hook 21 after poppet 18 and seat cushion 12 are broken away from, unclamp turning rack and regulate handle 6 and pull and connect pin handle 34 and make turning rack 1 be in free state.Upwards draw steering handle 9 forward, the transverse tube of pressing on the pedal support 2 is pulled connecting bore to engaging after poppet 18, adjusts steering handle 9 fastening adjustment handle 6 to the proper angle.Press seat folder fin 16 and open backrest 13 handrails 14.Load onto power supply box 20 plug 33 that plugs in.
Working process of the present utility model is as follows: when the brake equipment on the motor 25 did not have energized, motor 25 was in braking mode.Advance and when travelling forward-reverse switch 49 is opened on forward gear, craspedodrome is travelled: steering handle 9 or steering handwheel are on the direction of craspedodrome, and turnon left travels: anti-clockwise rotation steering handle 9 or steering handwheel, the big more Turning radius of the angle of rotation is just more little.Right-hand corner travels: right-hand revolution steering handle 9 or steering handwheel, and the angle of rotation is big more, and the radius of turning is just more little.When rotating infinite speed variation handle 51 or actuating lever, brake equipment electromagnetic brake device 23 energized, brake off, while motor 25 power connections, start-up control mechanism exports big electric current, voltage, the running of drive motor 25 forwards.Retreat and travel: will advance, retreat switch 49 and open retreating and block when rotating infinite speed variation handle 51 or actuating lever, brake equipment electromagnetic brake device 23 energized, brake off, motor 25 power connection start-up control mechanisms export big electric current, voltage, drive motor 25 antiports simultaneously.Speed travels: speed is kept off mode switch 50, open when the position of fast retaining, the control mechanism horsepower output strengthens, motor 25 operating speves are accelerated, with speed keep off mode switch 50 open slowly the retaining the position time, the control mechanism horsepower output diminishes, motor 25 operating speves are slack-off.This infinite speed variation handle 51 or actuating lever are that stepless speed regulation rotation or the angle pressed are big more, and the operating speed of motor 25 is also fast more.Ramp to stop: infinite speed variation handle 51 or actuating lever slowly during return in the process of moving, control mechanism also control corresponding motor 25 slowly are decelerated to and stop.Control mechanism stops to make electromagnetic brake device 23 be in braking mode to 23 power supplies of brake equipment electromagnetic brake device simultaneously, stops thereby car is decelerated to.The electromagnetic brake device 23 that brake equipment can be mounted on the motor 25 also can be the mechanical type brake, also can be the braking effect of two kinds of brake whiles and usefulness.Make forward-reverse switch 49 in the closed position during parking, the car load power supply is cut off, and this moment, brake equipment was in braking mode.In the time of will towing after wanting Trolley or folding, the mechanical brake clutch handle 24 that can pull on the brake equipment electromagnetic brake device 23 is removed drags.Disconnecting BK Brake Switch 53 simultaneously makes two drive wheels 8 become free gear, forward-reverse switch 49 rotates infinite speed variation handle 51 or actuating lever motor 25 can not start yet, turn round if open this moment, therefore car is in and does not have braking brake switch 53 to be in to open circuit the time, start car and must pull mechanical brake clutch handle 24 and make car be in the braking brake state.
Ride instead of walk subtracting in the car, differential drive system working process of described folding electric is as follows: power drives worm screws 27 rotations by drive coupling 46 when motor 25 runnings, is passed to left half axle 29 right axle shafts 32 and outputs power by being installed in finishing bevel gear cuter 31 on left half axle 29 right axle shafts 32 by the finishing bevel gear cuter 31 that is installed on the worm gear 30 again thereby be passed to worm gear 30.The resistance of left half axle 29 resistance ratios right axle shafts (32) is big during left-hand rotation, and the power of motor 25 outputs mainly is passed to right axle shaft 32 by finishing bevel gear cuter 31 makes the revolution ratio left half axle 29 of right axle shaft 32 fast, thereby forms differential.The resistance of the resistance ratios left half axle 29 of right axle shaft 32 is big during right-hand corner, and the power of motor 25 outputs mainly is passed to left half axle 29 by finishing bevel gear cuter 31 makes the revolution ratio right axle shaft 32 of left half axle 29 fast, thereby forms differential.
