A charging cable winding device

Abstract

The invention relates to a charging cable rolling device. The charging cable rolling device comprises a charging pile, wherein a supporting plate is arranged on the lower front side of the charging pile, two sliding channels are formed in the left side and the right side of the supporting plate respectively, sliding blocks are arranged inside the sliding channels, tension springs are connected to the outer ends of the sliding blocks respectively, and the other ends of the tension springs are correspondingly connected to the ends of the supporting plate. A rolling wheel is movably installed in the middle of the front end face of the supporting plate, a concave circle is arranged on the periphery face of the rolling wheel, two traction cables which are in central symmetry about the axis of the rolling wheel penetrate through the middle of the rolling wheel, and the two ends of each traction cable are connected to the sliding blocks on the corresponding sides respectively. The traction cables are adopted for preventing the rolling wheel from rotating; after the rolling wheel rotates, restoring force of the traction cables enables the rolling wheel to restore into an original shape, and in this way, a charging cable released and wound around the rolling wheel is rolled again. A rolling mode of low efficiency caused by manual rolling in the prior art is changed, and a driving device and a control system used for motor driving in the prior art are omitted.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging equipment, in particular to a charging cable winding device. Background technique [0002] With the depletion of traditional energy sources and the increasingly serious environmental pollution, people urgently need clean new energy sources. [0003] Electric energy is one of the energy sources with low pollution and wide sources, and is widely welcomed by people. [0004] Cars are one of the indispensable tools for people's life and travel. Affected by changes in energy and the environment, electric vehicles are becoming more and more popular. The charging process of electric vehicles requires the assistance of charging piles, which are the most influential equipment in the popularization of electric vehicles. The transformer box in the charging pile contains the electrical components that convert between the household power supply and the car power supply. When the transformer...

Problems solved by technology

The transformer box in the charging pile contains the electrical components that convert between the household power supply and the car power supply. When the transformer box of the charging pile is assembled, it needs to be fixed firmly with bolts. However, due to the large thickness of the transformer box of the charging pile, the bolts The length of the bolt is long, and it takes a long time to tighten or unload the bolt during the assembly process, which affects the production efficiency
