The specific embodiment:
Embodiment 1:
Referring to Fig. 1, Fig. 2, in the present embodiment, upper footboard 1 and lower shoe 2 are connected to linkwork by adapter shaft 3, at its articulated position place, are provided with return spring 18, and the circuit box 5 that is provided with sensor 4 is fixedly installed on the belly of upper footboard 1, rotates with upper footboard 1; Pivot arm 6 is connected in the rotating hole of upper footboard 1 by square rotating shaft 7, and the front end of pivot arm 6 is provided with roller 8, and roller 8 is the rolling plane with lower shoe 2; Retracing spring 9 on the pivot arm 6 resets at upper footboard 1 (shown in Figure 1) on the position of lifting.Magnet steel 10 is and square rotating shaft 7 interlocks, and is for the different rotational angle of square rotating shaft 7, corresponding with it with distances different between magnet steel 10 and the sensor 4.Adopt square rotating shaft can guarantee the servo-actuated performance that it is good.
Fig. 1, shown in Figure 2 is provided with rotary magnet steel transmission device, and magnet steel 10 is fixedly installed on the excircle of square rotating shaft 7, is the rotation on the circumferencial direction.
In the use:
When the operating personal seat of getting on the bus, open key switch, after removing hand braking and pushing to the vehicle operating direction switch, vehicle control system enters mode of operation.This moment, accelerator was in initialization state as shown in Figure 1, but did not have system start-up signal and Acceleration Signal output, elec. vehicle transfixion.
When operating personal is placed on right crus of diaphragm on the accelerator upper footboard 1 and begins to step on pedal 1 downwards.Because magnet steel 10 is to be connected by square rotating shaft 7 with pivot arm 6, magnet steel 10 rotates synchronously.Upper footboard 1 promptly is rotated down by anticlockwise direction, pivot arm 6 and roller 8 are done reversing sense, promptly move clockwise, magnetic field begins to change, exert an influence by 14 pairs of Hall elements 4 of last magnetic boots, when upper footboard 1 was rotated down 3-5 and spends, circuit is output control system trigger voltage and the vehicle accelerated voltage of creeping at first.Along with upper footboard 1 continues to be rotated down, trigger voltage is maintained, and since the rotation of magnet steel, accelerated voltage output even variation, thus stably control circuit chopper outgoing current is ascending, and elec. vehicle is given it the gun from slow to fast.
When upper footboard 1 is rotated down when reaching end position, be state as shown in Figure 2, pivot arm 6 left-hand revolutions 90 degree, this at present 15 pairs of Hall elements 4 of magnetic boots exert an influence because changes of magnetic field, circuit is exported maximum Acceleration Signal, elec. vehicle reaches high-ball.This moment, retracing spring all was in impaction state everywhere.
When elec. vehicle need slow down, the operating personal right crus of diaphragm returns to be lifted, under the effect of retracing spring 9, upper footboard 1 makes progress, i.e. clickwise, pivot arm 6 and roller 8 left-hand revolutions, magnet steel 10 synchronous left-hand revolutions, magnetic field changing inversely, the descending even output of Acceleration Signal, the descending even variation of chopper outgoing current in the control circuit, elec. vehicle slows down thereupon.When upper footboard 1 was got back to initial position, system start-up voltage was closed, and elec. vehicle driven by power power is eliminated.
Need glancing impact when elec. vehicle meets road conditions in the process of moving, the operating personal right crus of diaphragm will immediately leave accelerator then trample foot brake, begin brake.At this moment, under the effect of retracing spring, upper footboard 1 is got back to initial position shown in Figure 1 rapidly, the automatic closing system trigger voltage, and close electric current of chopper output, and the drive motor stall, elec. vehicle slides, and by foot brake vehicle is stopped immediately.
Embodiment 2:
Referring to Fig. 2, Fig. 3, present embodiment and embodiment 1 different only being parallel-moving type magnet steel transmission device is set, in square rotating shaft 7, connect firmly intentionally type cam 11, on the translation slide block 12 that magnet steel 10 is fixedly installed on the side that is arranged in sensor 4, be slidingly arranged in guide groove 17, the end that the outer end of translation slide block 12 is resisted against on the flange of heart type cam 11 by slide block roller 13, translation slide block 12 is arranged in guide groove 17 is provided with return compression spring 16.
In the present embodiment, what connect firmly with square rotating shaft 7 is heart type cam 11, because of heart type cam 11 with upper footboard 1 rotation, promote translation slide blocks 12 by slide block roller 13 and make motion of translation.Magnet steel 10 translation thereupon, in the translation process equably near or away from sensor 4, sensor is exerted an influence, make circuit output Acceleration Signal, and further by circuit control chopper output driving current.The safety measure of translation slide block 12 reliable returns is to adopt two return compression springs 16.Because the friction force of translation slide block 12 in motion guide groove 17 is very little, and the weight of translation slide block 12 is lighter, even two return compression springs 16 rupture simultaneously, but because of return compression spring 16 is fixedly installed in the motion guide groove 17, be unlikely to break away from translation slide block and circuit box, translation slide block 12 is resetted.Guarantee the safety traffic of elec. vehicle.
In concrete the enforcement, the utility model adopts single linear hall sensor 4 and single magnet steel 10, and the two-way output by signal can obtain simultaneously as the trigger voltage of on-off signal and the two-way voltage signal of vehicle accelerated voltage.
