Problems solved by technology

However, if the contact port protrudes from the outside, it is unsightly and the contact port is easily polluted by foreign matter from the outside, resulting in poor contact
Moreover, if the user does not pay attention and the battery is short-circuited or exposed to moisture, the charging energy will easily disappear.

Abstract

The invention discloses an electricity transmission device for a wireless power communication system. The electricity transmission device for the wireless power communication system comprises an AC / DC converter, a central control unit, an object sensor, a switch control unit, a series resonance converter, an actuator, a rectification unit, a receiving control unit and a battery unit, wherein the AC / DC converter is connected with the central control unit, the central control unit is connected with the object sensor, and the switch control unit is connected with the central control unit. According to the electricity transmission device for the wireless power communication system, the series resonance converter and the object sensor are used for inducing electromagnetism, and a charging unit is controlled through the two control units. The electricity transmission device for the wireless power communication system has the advantages that mutual contact between contact ports is avoided, the degree of shielding against a magnetic field is improved, and receiving sensitivity is improved.

Description

technical field [0001] The invention relates to a power transmission device for a wireless power communication system. Background technique [0002] Generally, a rechargeable secondary battery is installed as a battery in a portable electronic device. To charge the battery, an additional charging device that supplies power to the battery of the portable electronic device from a household power supply is required. Usually, additional contact ports are respectively provided on the outside of the charging device and the battery, so that the charging device and the battery are electrically connected to each other by connecting the two contact ports. However, if the contact port protrudes from the outside, it is unsightly and the contact port is easily polluted by foreign matter from the outside, resulting in poor contact. Moreover, if the battery is short-circuited or exposed to moisture without the user's attention, the charging energy will easily disappear. Contents of ...
