Abstract

The invention relates to the technical field of wireless power transmission, and particularly discloses a segmented guide rail type wireless energy transmitting mechanism with a signal coil and a transmission system. The system comprises a transmitting end and a receiving end, wherein the transmitting end is a wireless energy transmitting mechanism and comprises a plurality of segments of guide rail type wireless energy transmitting coils and primary side signal coils overlapped with the guide rail type wireless energy transmitting coils, and each segment of guide rail type wireless energy transmitting coil is of a DD type energy transmitting coil structure; the primary side signal coils are integrally arranged in parallel to form a Q-shaped primary side signal coil structure in the widthdirection relative to the plurality of segments of guide rail type wireless energy transmitting coils; the receiving end comprises a secondary side signal coil and a wireless energy receiving coil, the secondary side signal coil is arranged to be of a Q-shaped secondary side signal coil structure, and the wireless energy receiving coil is arranged to be of a DD-shaped energy receiving coil structure. The energy and signal transmission channels respectively adopt the DD type coil and the Q type coil, and the DD coil and the Q coil can realize natural decoupling, so that parallel transmission ofenergy and signals is realized.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a segmented guide rail type wireless energy transmitting mechanism with a signal coil and a transmission system. Background technique [0002] Wireless charging technology has the advantages of flexibility, reliability and safety. It is more and more widely used in fields such as drones, home appliances and electric vehicles. In order to achieve optimal system energy efficiency and status monitoring, and improve the performance of the wireless charging system, the wireless charging system often requires communication and interaction information between the primary and secondary sides. [0003] However, during the dynamic charging process, the power receiving end is in a state of rapid movement. Traditional communication methods such as WiFi and Zigbee take a long time to access, and the transmission speed is slow and cannot meet the communication requirement...
