Charging pile take-up and pay-off device with motor matched with movable pulley

Abstract

The invention discloses a charging pile take-up and pay-off device with a motor matched with a movable pulley. The charging pile take-up and pay-off device with the motor matched with the movable pulley comprises a base plate, wherein a top plate is arranged above the base plate; the base plate and the top plate are fixedly connected through a fixing rod; a guide rod is fixedly installed between the base plate and the top plate; a balancing weight is slidably connected onto the guide rod; and a second fixing block is fixedly installed on the balancing weight. According to the charging pile take-up and pay-off device with the motor matched with the movable pulley provided by the invention, when charging is needed, a second driving motor is started to rotate forwards, a driving wheel is driven to rotate forwards, a cable is driven to be transmitted outwards along an opening of a bent block through friction force between the driving wheel and the cable, at the moment, a movable pulley is pulled by the cable to move upwards, the distance between the movable pulley and a fixed pulley is reduced, and the length of the cable stored between the movable pulley and the fixed pulley is reduced, so that the pay-off function of the device is achieved, a user does not need to pick up the cable and separate the cable circle by circle for use, the burden of the user is reduced, and the device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of take-up and take-off devices, in particular to a take-up and take-off device for a charging pile with a motor and a movable pulley. Background technique [0002] Electric vehicles refer to vehicles with advanced technical principles, new technologies and new structures that use electric energy as a power source. The use of electric vehicles is inseparable from charging piles. [0003] The function of the charging pile is similar to the fuel dispenser in the gas station. It can be fixed on the ground or wall, and installed in the parking lot or charging station of public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. The charging pile The input end of the battery is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. [0004] However, the existing charging p...

Problems solved by technology

[0005] 1. The cable loop on the traditional charging pile is hung on the wire rack. It takes time for the user to disassemble the cable loops before using it every time charging, and the cable is relatively thick and heavy. It takes a certain amount of effort to get up, which increases the burden on users;

[0006] 2. The cables on the traditional charging piles are usually made relatively long, and the cables will be dragged on the ground. Because the ground environment is not controlled, the cables are easy to rub against the ground, which will cause the cables to be damaged, and the cables are in contact with the ground. It is easy to be contaminated with dust, causing the cable to be unclean, causing the dust on the cable to stain people's clothes and hands, and making it difficult to use the device
