Embodiment Construction
[0018] Below in conjunction with accompanying drawing, invention is described in further detail.
[0019] figure 1 A wheel steering return device according to an embodiment of the present invention is schematically shown.
[0020] refer to figure 1 The wheel steering return device includes a fixed seat 1, a first gear 2, a second gear 3, a second PCB board 5, a thimble 6, a linkage mechanism 7, a first rotating shaft 8, a second rotating shaft 9, a motor and a main control unit .
[0021] The first gear 2 is driven by the motor, the first gear 2 meshes with the second gear 3, and the rotation of the first gear 2 can drive the second gear 3 to rotate. The second PCB board 5 is fixedly arranged on the fixing seat 1, the second PCB board 5 is provided with a conductive contact 51, the first PCB board 4 is fixed on the second gear 3, and the thimble 6 is fixed on the second gear 3 and connected with the first PCB board 4. Electrically connected, one end of the thimble 6 corres...

The invention discloses a wheel turning return device. The wheel turning return device comprises a first gear, a second gear, a second PCB (printed circuit board), an ejection pin, a motor and a main control unit, wherein the first gear is driven by the motor, and is engaged with the second gear; the second PCB is fixedly arranged, and provided with a conductive contact; the ejection pin is fixed to the second gear, and one end of the ejection pin corresponds to and can be contacted with the conductive contact; the ejection pin, the second PCB and the motor are all electrically connected with the main control unit. Therefore, the main control unit can control the motor to rotate, the motor drives the first gear, the first gear can drive the second gear to rotate, the second gear rotates and can drive a wheel to turn through a link mechanism connected with the second gear, and the ejection pin gets away from the conductive contact; after turning is in place, the motor reversely rotates and drives the first gear to reversely rotate, and the second gear is driven to reversely rotate, so that the wheel returns; the ejection pin can generate a stopping signal and sends the stopping signal to the main control unit when contacted with the conductive contact, the main control unit controls the motor to stop rotating based on the signal, and the wheel is enabled to just stay in a position of a straight line. Turning of the wheel and precise control over returning can be achieved, a car running position is precise, and control is facilitated.
Description
technical field [0001] The invention relates to a toy car device, in particular to a wheel steering return device and a wheel steering return control method. Background technique [0002] The electric remote control vehicle of the prior art needs to be provided with steering mechanism, generally adopts extension spring type steering mechanism or straight arm torsion spring type steering mechanism. After the wheels are turned in place through the steering mechanism, the wheels are automatically returned to the center by the spring force. After a period of use, the resilience of the spring weakens, and it is usually difficult for the wheels to return to the correct position. The car cannot run in a straight line, and the handling is inconvenient. Contents of the invention [0003] The invention provides a wheel steering return device and a control method for the device, which solve one of the above technical problems. [0004] According to one aspect of the present inventi...
