[0064] Based on the above scheme, the number of the above magnetic balls 4 can be designed according to the requirements, such as 2 or 4.

[0065] Example 10

[0066] Based on the above embodiments, this embodiment also provides a tractor, including wheels with in-tire power generation function as described above.

[0067] This embodiment also provides a tractor with a simple structure and reasonable design. The tractor provides power to the electrical equipment inside the tires through a generator and is easy to use.

[0068] The working principle of this utility model is as follows:

[0069] During use, when the tractor is working, the magnetic ball 4 rolls inside the coil tube 3, generating voltage at both ends of the coil, thereby providing power to the electrical equipment inside the tire.

[0070] This invention mainly involves placing a coil tube and a magnetic ball inside the tire. When the tractor is working, the magnetic ball rolls inside the coil tube, generating voltage at both ends of the coil, thereby providing power to the electrical equipment inside the tire.

[0071] This invention utilizes the rotation of the tires when the tractor is working. The coil pipe 3 is fixed on the wheel hub and follows the tire development. The magnetic balls 4 (the number is not limited) placed inside the pipe will roll inside the pipe due to gravity and friction, thereby generating voltage at both ends of the coil. Through subsequent circuit processing such as rectification and filtering, the sensor inside the tire can be powered.

[0072] The specific principle behind how the magnetic ball 4 changes the voltage across the coil as it rolls within the coil tube 3 is as follows: The principle by which the rolling magnetic ball generates voltage within the coil is based on the principle of magnetoelectric induction. When the magnetic ball rolls within the coil, it cuts magnetic lines of force, thereby inducing a voltage within the coil.

[0073] Specifically, when a magnetic ball rolls inside a coil, it alters the magnetic field distribution within the coil, causing the magnetic field lines in the coil to be cut. According to Faraday's law of electromagnetic induction, when a conductor moves in a magnetic field and cuts magnetic field lines, an electromotive force is generated in the conductor, thus producing current and voltage. This principle is widely used in various electromagnetic induction sensors to measure and detect changes in magnetic fields.

[0074] Furthermore, the relative motion between the magnetic ball and the coil generates a changing magnetic field, which in turn induces an electromotive force (EMF) in the coil. The magnitude of this EMF depends on the speed of the magnetic ball and the number of turns in the coil; the faster the speed, the greater the induced EMF. This phenomenon not only occurs when the magnetic ball rolls but can also be applied to vibration velocity sensors, where the magnitude of vibration velocity or displacement is detected by measuring the induced voltage.

[0075] It should be noted that all electronic components involved in this utility model adopt existing technology, and all the above-mentioned components are electrically connected to the controller, and the control circuit between the controller and each component is existing technology.

[0076] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
