Abstract

The invention relates to the technical field of wireless electric energy transmission, and particularly discloses an energy signal simultaneous transmission structure and a dynamic wireless energy transmission system. The system comprises a transmitting end and a receiving end. The transmitting end is an energy signal simultaneous transmission structure and comprises a plurality of sections 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 section of guide rail type wireless energy transmitting coil is of a Q-shaped energy transmitting coil structure; the primary side signal coil is integrally arranged in parallel to form a DD type primary side signal coil structure in the width direction relative to the multi-section guide rail type wireless energy transmitting coil; 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 DD type secondary side signal coil structure, and the wireless energy receiving coil is arranged to be of a Q type energy receiving coil structure. A DD typecoil and a Q type coil are adopted in a signal transmission channel and an energy transmission channel respectively, and due to the fact that the DD coil and the Q coil can achieve natural decoupling, parallel transmission of energy and signals is achieved.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to an energy signal simultaneous transmission structure and a dynamic wireless energy 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 requirements of dyna...
