Problems solved by technology

[0003] However, most of the charging stands for mobile smart terminals on the market do not have the function of controlling voltage output. As long as the charging stand is connected to a power source, the charging stand will output a voltage of 5V
Since most of the current charging bases use contact charging, such as using pogo pins as charging contacts, and the metal contacts are charged and exposed to the air for a long time, they are prone to electrochemical corrosion, which will eventually lead to contact impedance. becomes larger, thus affecting the effect of charging

Abstract

The invention discloses a charging stand, comprising: a charging circuit, a switch circuit, a first connection part, a second connection part and a third connection part; wherein, the input end of the charging circuit is a power supply connection end, and the charging circuit The output end of the connection is connected to the first connection part, the second connection part is a ground terminal, and the third connection part is connected to the switch circuit; when the charging stand is connected to a power supply and the charging stand is empty , the third connection part is in a suspended state, and the switch circuit disconnects the charging circuit to stop supplying power to the first connection part; when the charging stand is connected to a power source and the charging stand is loaded, the The third connection part and the second connection part are in a short-circuit state, and the switch circuit conducts the charging circuit to supply power to the first connection part. The present invention controls the output voltage of the charging base to prevent the metal contacts from being charged and exposed to the air when they are not connected to the load, thereby effectively ensuring the charging effect.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a charging stand for a mobile smart terminal. Background technique [0002] With the popularization of mobile intelligent terminals such as smartphones, tablet computers, and wearable devices, various charging methods have emerged as the times require. The mobile smart terminal is charged through the charging stand, and the support function of the charging stand can be used to meet the user's needs for using the mobile smart terminal while charging. [0003] However, most of the charging stands for mobile smart terminals on the market do not have the function of controlling voltage output. As long as the charging stand is connected to a power source, the charging stand will output a voltage of 5V. Since most of the current charging bases use contact charging, such as using pogo pins as charging contacts, and the metal contacts are charged and exposed to the air for a ...
