Pipe rolling device for charging pile

Abstract

The invention discloses a pipe rolling device for a charging pile for new-energy electric cars. The pipe rolling device comprises a shield, a shell, a power source universal rotating converter, a winding drum, a stepless reversing locker, a pipe rolling device main shaft and a power spring coil spring. The power source universal rotating converter comprises a converter fixing shaft, rotating conversion assemblies for connecting multiple wires, a rotary moving ring-shaped metal copper sheet and multiple flame-retardant insulators. The outer edge of the rotary moving ring-shaped metal copper sheet is provided with N concave semi-circles. The N concave semi-circles are buckled with N round bosses of the flame-retardant insulators, and synchronous rotary motion is formed. The multiple flame-retardant insulators are sequentially connected and spliced in a 90-degree dislocation manner through the concave-convex structure to form a whole, the converter fixing shaft is sleeved with the flame-retardant insulators in a clearance fit manner, and the rotating conversion assemblies for connecting the wires are wrapped in all small spaces correspondingly. The pipe rolling device for the chargingpile can prolong the service life of cables of the charging pile and improve use safety of the charging pile.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a hose reel for charging piles of new energy electric vehicles. Background technique [0002] At present, the cables of charging piles below 10 kW for new energy electric vehicles are generally in a state of manual winding, without automatic storage devices. It is easy to be run over and damaged by vehicles, especially when used outdoors, exposed to the sun and rain, messy, severely damaged, dangerous and unsafe. Even if a small number of charging stations are managed by special personnel, the labor intensity is high and the cost is high. This kind of charging pile structure has high requirements on the location of the installation environment, difficulty in promotion, and poor user experience. Contents of the invention [0003] In view of the above technical problems, the present invention proposes a hose reel for charging piles. When charging new energy electric vehicles, the user ...
