Description

Technical Field

[0001] The utility model relates to the technical field of experimental devices, in particular to a magnetic coupling wireless power transmission experimental device. Background Technique

[0002] Wireless energy transmission technology generally includes electromagnetic wave wireless energy transmission technology, inductive coupling wireless energy transmission technology, and magnetic coupling resonance wireless energy transmission technology; in the existing technology, such as the Chinese utility model patent authorized on September 25, 2020, with the authorization announcement number of CN211578197U, which discloses a new type of wireless power transmission experimental instrument, including an experimental device and a host device. The experimental device includes a base, a transmitting coil, a receiving coil, and a guide rail. The transmitting coil and the guide rail are both fixed on the base, and the transmitting coil is arranged on the front side of the guide rail. The receiving coil is movably arranged on the guide rail. The base is provided with a distance adjusting mechanism for adjusting the distance between the transmitting coil and the receiving coil, and the receiving coil is connected to the distance adjusting mechanism; the host device includes a housing, an operation panel is arranged on the housing, an MCU main controller is arranged inside the housing, the distance adjusting mechanism and the operation panel are both connected to the MCU main controller, and the MCU main controller is respectively connected with a signal transmitting module and a signal receiving module. The transmitting coil is connected to the signal transmitting module, and the receiving coil is connected to the signal receiving module;

[0003] In this technical solution, only a receiving coil and a transmitting coil are provided. When the distance between the receiving coil and the transmitting coil is relatively far, the intensity of the transmitted wireless electric energy will decrease, so that it cannot be used for long-distance transmission. Moreover, in the solution, the receiving coil and the transmitting coil can only be adjusted in a straight line distance, and the receiving coil and the transmitting coil cannot be rotated at different angles to experiment on the wireless transmission intensity, thus narrowing the experimental scope. For this reason, a magnetic coupling wireless power transmission experimental device that can maintain the wireless electric energy intensity and perform long-distance transmission and can expand the experimental scope is proposed.
