Description

M381217 V. New Description: [New Technology Field] This creation system provides an inductive charging system, especially an inductive charging system that automatically starts the charging process based on the strength of the power signal converted by the inductive signal. [Prior Art] Due to the advancement of technology, many everyday life is filled with electronic products to help people live. For example, the electronic product can be an auto-cleaning robot. The charging method of a general robot can be divided into a contact charging method and a non-contact charging method. The robot using the non-contact charging method has a power supply end and a charging end, which utilizes a magnetic flux change of a magnetic induction signal emitted from the power supply end to sense the corresponding magnetic induction signal of the charging end, and the charging end simultaneously The sensed magnetic induction signal is converted into a power signal to complete the non-contact charging process. However, the inductive strength of the magnetic induction signal is rapidly attenuated as the distance between the power supply terminal and the charging terminal increases, meaning that the power transmission efficiency of the non-contact charging method varies with the distance between the power supply terminal and the charging terminal. The increase and decrease greatly, so the robot using the non-contact charging method needs to additionally provide a detecting component, such as an optical detecting component, on the power supply end and the charging end, thereby detecting the power supply terminal M381217, and the charging end. The distance between the two changes, and drives the charging terminal into the power supply end. Within the power supply tolerance range. Therefore, the robot using the non-contact charging method is relatively expensive to manufacture and has poor power transmission efficiency. For the above reasons, most of today's robots use contact charging methods. A robot using a contact charging method directly connects a power transmission component to an external power supply device to obtain power. This kind of power supply method. Although there is high power transmission efficiency, the robot needs to accurately position the power transmission component to the external power supply device, and the tolerance of the positioning error is extremely small, which causes inconvenience in use. In addition, the contact charging method requires at least one conductive contact at the power supply end and the charging end, and the conductive contact is used to transmit current when the power supply end and the charging end contact each other. Therefore, the contact charging method is prone to accidental occurrence of leakage or short circuit due to the exposed conductive contact, and the charging is performed if the conductive contact of the charging end is not properly contacted with the conductive contact of the power supply terminal. The terminal cannot effectively obtain the required power from the power supply terminal. Therefore, how to design a charging system that combines the convenience of the non-contact charging method - and the high power transmission efficiency of the contact charging method - is an important goal of the efforts required for power transmission technology. [New content] This creative system provides an inductive charging system that automatically activates the charging program based on the power signal converted by the inductive signal to solve the above problem.
