Fig. 3 is circuit connection schematic diagram of the present utility model.Therein 17 is single-chip microcomputer, and 18 is relay, and 19 is circuit board, and 20 is electric motor car power supply circuits, and 21 is battery of electric vehicle.
Detailed description of the invention
Below in conjunction with accompanying drawing and use, this utility model is further illustrated.
Hall switch signal output part of the present utility model is connected with single-chip microcomputer input pin through holding wire, horn button outfan is connected with single-chip microcomputer input pin through holding wire, relay input is connected with single-chip microcomputer output pin through holding wire, and relay output end is then connected in the battery feed circuit of electric motor car.
Magnetic box of the present utility model is welded on screw tip, built with ferromagnetism Magnet, screw rod can precession internal thread cylinder, for regulating the distance of Hall switch and magnetic box, turn locking nut and realize the fixing of screw rod and internal thread cylinder；The motor fixing screw of rear wheels of electric vehicle is placed in the fixing hole on base plate and realizes fixing.
Hall switch and trailing wheel axis screw rod are respectively placed in two fixing holes of Hall switch stator, it is achieved Hall switch fixing, turn Hall switch and carry fixing nut and realize the fixing of Hall switch；Single-chip microcomputer welds on circuit boards, and relay is fixing on circuit boards, and circuit board is screwed in bottom circuit box, and circuit box is arranged on the gap in electromobile battery case.Electric motor car supply lines by the position of below-seat, can disconnect supply lines at vehicle seat position in vehicle frame, and the supply lines that two disconnect is connected to relay output end.
In this utility model use procedure, when electric motor car travels, Magnet and Hall switch have relative motion, Hall switch to export one group of high level signal being interrupted to single-chip microcomputer, single-chip microcomputer exports stable low level signal to relay, relay Guan Bi power supply circuits after differentiating.When electromobile stops, Hall switch and magnetic box geo-stationary, Hall switch output low level or constant high level are to single-chip microcomputer, and single-chip microcomputer exports stable high level to relay after differentiating, relay disconnects power supply circuits.Therefore, when electromobile travels, relay closes power supply circuits all the time；When electromobile stops, relay disconnects supply line, even if at this moment twisting handlebar, electromobile is without starting motion.
And when electric motor car needs to start, only need to being consecutively pressed twice horn button, pass to the high level signal signal of telecommunication pulse that single-chip microcomputer is interrupted, single-chip microcomputer one low level signal of output is to relay, at this moment power supply circuits connected by relay, and twisting handlebar knob electric motor car just can start to walk.
Single-chip microcomputer of the present utility model is as preferably employing general AT89S52 chip, and it is 8 8-digit microcontrollers of a kind of low-power consumption, high-performance CMOS, has 8K in-system programmable components flash storage.AT89S52 has following standard feature: 256 byte RAM, 32 I/0 mouth lines, three 16 bit timing devices/enumerators, has crystal oscillator and clock circuit in sheet.Hall switch then adopts unipolarity Hall switch.
The safe starting and stopping mechanism of electric motor car of the present utility model is prevented from the situation that unexpected twisting handlebar causes electric motor car to start to walk to go out, and improves the travel safety of electric motor car.
