[0024] As shown in Figs. 1 to 4 The embodiments of the present application provide a toy car automatic tracking driving method, which comprises the following steps: Step 1. Set a driving plane 1, and set a running track line 2 on the driving plane 1, wherein the driving plane 1 and the running track line 2 have a color difference, so that the driving plane 1 and the running track line 2 have obvious difference in reflection intensity of infrared rays; Step 2. Set a toy car body 3, and set a left infrared ray group 4 and a right infrared ray group 5 on the toy car body 3 corresponding to the running track line 2; The toy car body 3 is provided with a left wheel 6 and a right wheel 7, and the toy car body 3 is provided with a controller for controlling the rotation of the left wheel 6 and the right wheel 7; Step 3. Put the toy car body 3 on the driving plane 1, and the left infrared ray group 4 and the right infrared ray group 5 are located on both sides of the running track line 2; The left wheel 6 and the right wheel 7 are located on both sides of the running track line 2; When the traveling trajectory line is straight, the infrared rays emitted by the left infrared group 4 and the right infrared group 5 all fall on the traveling plane 1, so that the reflected infrared rays have approximately the same intensity, and the toy car body 3 keeps straight driving along the traveling trajectory line 2. When the traveling trajectory line 2 is curved, the infrared rays emitted by the left infrared group 4 or the right infrared group 5 fall on the traveling trajectory line 2, so that the infrared rays reflected to the corresponding infrared group have different intensity from the infrared rays received by the other infrared group, the controller controls the wheels on the side of the corresponding infrared group to stop rotating, and the wheels on the side of the other infrared group continue to rotate until the two wheels return to the two sides of the traveling trajectory line 2.
[0025] The traveling plane 1 and the traveling trajectory line 2 need to have obvious color difference, the traveling plane 1 is dark and the traveling trajectory line 2 is light, or the traveling plane 1 is light and the traveling trajectory line 2 is dark, such arrangement makes the infrared intensity reflected by the traveling trajectory line 2 to the infrared group obviously different from the infrared intensity reflected by the traveling plane 1 to the infrared group.
[0026] When the reflected signal sizes received by the left infrared group 4 and the right infrared group 5 are the same, the traveling trajectory line 2 is located between the left infrared group 4 and the right infrared group 5, at this time the traveling trajectory line 2 is straight, so the left wheel 6 and the right wheel 7 continue to normally rotate, and the toy car drives straight.
[0027] When the reflected signal sizes received by the left infrared group 4 and the right infrared group 5 are different, the infrared rays emitted by one infrared group irradiate the traveling trajectory line 2 and are reflected back to the infrared group, at this time the traveling trajectory line 2 is curved, the controller controls the wheels on one side to stop rotating and the wheels on the other side to continue rotating, so that the vehicle turns along the curved traveling trajectory line 2. Until the reflected signal sizes received by the left infrared group 4 and the right infrared group 5 are the same again, the toy car drives straight.
[0028] The traveling plane 1 is white and the traveling trajectory line 2 is black. When the traveling trajectory line 2 is dark, the reflected infrared signal intensity irradiated on the traveling trajectory line 2 is weaker than the reflected infrared signal intensity irradiated on the traveling plane 1.
[0029] The left infrared group 4 and the right infrared group 5 are arranged at the bottom of the toy car body 3, the left infrared group 4 and the left wheel 6 are located at the left side of the bottom of the car, and the right infrared group 5 and the right wheel 7 are located at the right side of the bottom of the car.
[0030] In other embodiments, the left infrared group 4 and the right infrared group 5 can be arranged at the front end of the toy car body 3, as long as they are symmetrically arranged relative to the middle line of the toy car.
[0031] The left infrared group 4 and the right infrared group 5 are identical in structure, each comprising an infrared emitter and an infrared receiver. The left infrared group 4 and the right infrared group 5 are electrically connected to the controller, which is an MCU. The controller controls the left wheel 6 and the right wheel 7 to stop or rotate by judging the signal received by the infrared receiver.
[0032] In step 4, when the travel trajectory line 2 is bent to the left, the infrared emitted by the left infrared group 4 falls on the travel trajectory line 2, and the infrared emitted by the right infrared group 5 falls on the travel plane. Thus, the infrared reflected back to the left infrared group 4 is weaker than the infrared reflected back to the right infrared group 5. The left wheel 6 stops rotating, and the right wheel 7 continues to work normally, so that the toy car turns left along the travel trajectory line 2.
[0033] In step 4, when the travel trajectory line 2 is bent to the right, the infrared emitted by the right infrared group 5 falls on the travel trajectory line 2, and the infrared emitted by the left infrared group 4 falls on the travel plane. Thus, the infrared reflected back to the right infrared group 5 is weaker than the infrared reflected back to the left infrared group 4. The right wheel 7 stops rotating, and the left wheel 6 continues to work normally, so that the toy car turns right along the travel trajectory line 2.
[0034] When passing through the intersected travel trajectory line 2, the toy car directly rushes through the transversely arranged travel trajectory line 2 according to inertia and continues to travel in the original direction. Alternatively, when the reflected signal strength received by the left infrared group 4 and the right infrared group 5 is the same, the vehicle continues to travel straight forward.
[0035] In the process of vehicle travel, the controller constantly controls the left wheel 6 and the right wheel 7 to stop or rotate according to the strength of the reflected infrared, so that the toy car travels along the travel trajectory line 2 all the time. Even if the travel trajectory line 2 of different travel paths is replaced, the toy car can accurately travel along the travel trajectory line 2.
[0036] An automatic tracking travel toy car implementing the automatic tracking travel method of the toy car described above comprises a travel plane 1 provided with a travel trajectory line 2. The travel plane 1 and the travel trajectory line 2 have a color difference. The toy car body 3 is placed on the travel trajectory line 2. The toy car body 3 is provided with a left infrared group 4 and a right infrared group 5 corresponding to the travel trajectory line 2. The left infrared group 4 and the right infrared group 5 are located on both sides of the travel trajectory line 2.
[0037] The toy car further comprises a left wheel 6 and a right wheel 7, and a controller for controlling the left wheel 6 and the right wheel 7. The left wheel 6 and the right wheel 7 are arranged outside the left infrared group 4 and the right infrared group 5. The controller is arranged in the toy car body 3.
[0038] Specifically, the left wheel 6 and the right wheel 7 are front wheels of the toy car, which are driven to rotate by a motor in the toy car, and the motor is electrically connected with the controller.
[0039] In other embodiments, the left wheel 6 and the right wheel 7 can be wheels arranged in the middle of the bottom of the toy car, and other auxiliary wheels 8 can be arranged at the front end and the rear end of the bottom of the toy car.
[0040] The left infrared group 4 and the right infrared group 5 are arranged at the bottom of the toy car body 3, and the left infrared group 4 and the right infrared group 5 are symmetrically arranged relative to the middle line of the toy car body 3.
[0041] The left wheel 6, the left infrared group 4, the right infrared group 5 and the right wheel 7 are arranged in a row, so that when the left infrared group 4 and the right infrared group 5 receive the reflected signals, the controller can timely control the working state of the left wheel 6 and the right wheel 7 according to the signals.
[0042] In other embodiments, the left infrared group 4 and the right infrared group 5 can also be arranged at the front end of the toy car.
[0043] The left infrared group 4 and the right infrared group 5 are electrically connected with the controller.
[0044] The left infrared group 4 and the right infrared group 5 have the same structure, and each includes an infrared emitter and an infrared receiver, the left infrared group 4 and the right infrared group 5 are electrically connected with the controller, the controller is an MCU, and the controller controls the left wheel 6 and the right wheel 7 to stop or rotate by judging the size of the signal received by the infrared receiver.
[0045] The upper part of the toy car body 3 is provided with a hopper 9, which can be used to load other objects. The front end and the rear end of the toy car body 3 are respectively provided with a connecting mechanism 10 connected with other toy car bodies 3, so that a plurality of toy cars can be connected in series to form a train.
