Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 shows the STRUCTURE DECOMPOSITION figure of bipotential device 100.Bipotential device 100 comprises first potentiometer 1, second potentiometer 2, PCB circuit board 6 and center connecting axle 3.Effective control angular range of described first potentiometer 1 and second potentiometer 2 is 0 to 280 degree.Described first potentiometer 1 and second potentiometer 2 paste respectively on the positive and negative that is welded in described PCB circuit board 6 in the complementary mode of putting of 180 degree; The screw that one end is fixed on the steering wheel bottom of shell runs through this PCB and is connected with this PCB circuit board 6; Described center connecting axle 3 runs through second rotating parts 8 of first rotating parts 7, PCB circuit board 6 and second potentiometer 2 of described first potentiometer 1 successively, drives first rotating parts 7 and second rotating parts 8 rotates synchronously.

Further, described center connecting axle runs through second rotating parts of first rotating parts, PCB circuit board and second potentiometer of described first potentiometer, and mode and first rotating parts and second rotating parts are connected in relative rotation to limit it.The cross section of the part that the described center connecting axle and first rotating parts and second rotating part are connected can be irregular figures such as large semi-circular, semicircle, triangle, rhombus, and described first and second rotating parts have the through hole that cross section is corresponding irregular figure, rotate synchronously so that described center connecting axle drives first and second rotating partss simultaneously.

Fig. 2 shows the pin connection layout of potentiometer.Described first potentiometer 1 comprises the first power pins VCC1, the first slip pin K1 and the first grounding pin GND1, and described second potentiometer 2 comprises second source pin VCC2, the second slip pin K2 and the second grounding pin GND2; The first power pins VCC1 links to each other with second source pin VCC2, and is connected with the 3.3V dc power supply terminal of described PCB circuit board 6; The first grounding pin GND1 links to each other with the second grounding pin GND2, and is connected mutually with the ground end of described PCB circuit board 6; The first slip pin K1 and the second slip pin K2 draw respectively, and are connected with described PCB circuit board 6.

Further, the first slip pin K1 and the second slip pin K2 link to each other with ground end on the described PCB circuit board 6 by the electric capacity that is welded on the described PCB circuit board 6, with the interference signal on this pin of filtering.

Fig. 3 shows the location state diagram of the utility model and output gear 4.Described center connecting axle 3 runs through successively and is connected with described first potentiometer 1, PCB circuit board 6 and second potentiometer 2, its other end is connected mutually with the output gear 4 of train of reduction gears 5, and then the rotation of output gear 4 drives the rotation of center connecting axle 3, and then drives the rotation of described first potentiometer 1 or second potentiometer 2.Because effective control angular range of first potentiometer 1 and second potentiometer 2 is 0 to 280 degree, and above-mentioned two potentiometers weld in the complementary mode of putting of 180 degree and are attached on the described PCB circuit board 6, therefore, after this connected mode connection, first potentiometer 1 and second potentiometer 2 have at least one to be in the control range, that is to say that the control range of first potentiometer 1 outside 280 degree supplied by second potentiometer 2, and then connecting axle 3 slewing areas in center are 0 to 360 degree.

Fig. 4 shows the steering wheel structure chart that bipotential device 100 is housed, and with reference to this figure, the operation principle of steering wheel is the control signal in control circuit received signal source, and the motor rotation in the driving steering wheel; Shaft of motor is connected with the elementary of train of reduction gears 5, and train of reduction gears 5 becomes big multiple to dwindle the speed of motor, and the output torque of motor is amplified corresponding multiple, then through output gear 4 outputs; The center connecting axle 3 of bipotential device 100 rotates with the output gear 4 of gear train, measures the rotational angle of steering wheel; Described PCB circuit board 6 detects and judges the rotational angle of steering wheels according to bipotential device 100, controls steering wheel then and turns to angle on target or remain on angle on target.

Further,, so just can detect the rotational angle of steering wheel in 360 degree scopes, and then change control signal so that the rotational angle of steering wheel is followed angle on target by related algorithm because effective control angle of bipotential device 100 is 0 to 360 degree.
