Problems solved by technology

[0002] There will be many public charging stations in our life. Common charging stations can only supply power for electric vehicles or household appliances, and their functions are relatively single. When encountering the need to use high power, we need to find a transfer device to change the power , time-consuming and labor-intensive, at the same time, the simultaneous use of large and small power in the circuit is not conducive to circuit safety, accidents are prone to occur, and it will also affect the service life of the charging station. In order to solve the above problems, the present invention is proposed

Abstract

The invention discloses a high-low power switching power supply device. The device comprises a housing, and a sliding block is arranged at the left end of the shell in a left-right moving mode. A high-power socket is fixedly arranged in the sliding block; the right end of the high-power socket is fixedly connected with a first conductive block; a first groove is formed in the first conductive block; a conductive convex block is fixedly arranged in the first groove. According to the invention, the device is simple in structure and convenient to operate, can selectively use large and small powerfor power supply, automatically disconnects a small-power power supply device when large power is used for power supply, guarantees the stability of output power when large and small power is switched, can maintain daily power supply through an emergency power supply if an open circuit occurs in a circuit, is convenient and quick, and improves certain safety.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a large and small power switching power supply device. Background technique [0002] There will be many public charging stations in our life. Common charging stations can only supply power for electric vehicles or household appliances, and their functions are relatively single. When encountering the need to use high power, we need to find a transfer device to change the power , time-consuming and labor-intensive, and at the same time, the simultaneous use of large and small power in the circuit is not conducive to circuit safety, prone to accidents, and will also affect the service life of the charging station. In order to solve the above problems, the present invention is proposed. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a high-low power switching power supply device, which can over...
