Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a charging pile with an automatic wire-retracting function. Background Art

[0002] Electric vehicles are a green means of transportation with broad development prospects. Against the backdrop of severe global energy and environmental crises, it is very important to actively promote the application and development of new energy vehicles. Charging piles, as important supporting infrastructure necessary for the development of electric vehicles, have very important social and economic benefits. The function of charging piles is similar to that of gas pumps in gas stations. They can be fixed on the ground or on walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and parking lots or charging stations in residential areas. They can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. The charging pile display can display data such as charging capacity, cost, and charging time.

[0003] After searching, it was found in the Chinese Public Utility Model Patent Application No.: CN201720483642.0 that a charging pile with an automatic wire winding function was disclosed. The charging pile uses the cooperation between the tension spring and the pulling rope to provide a force for the rotation of the rotating shaft, so that the charging cable can be wound around the outside of the rotating shaft. However, during the use of the charging cable of the charging pile, the force of pulling the cable out of the winding chamber will increase with the elongation of the tension spring, which is time-consuming and labor-intensive to use, and is easy to damage the wire core inside the cable, thereby reducing the service life of the cable. At the same time, the wires are exposed to the outside during charging and are easily contaminated by environmental dirt. Utility Model Content

Two control buttons are arranged on the charging pile body 1, and the two control buttons are electrically connected to the motor 201, and the motor 201 is electrically connected to the external power supply. The left button controls the line release, and the right button controls the line retraction. By starting the motor 201, the output end of the motor 201 drives the driving shaft 202 to rotate, and the driving shaft 202 drives the bevel gear 204 thereon to rotate. Since the two bevel gears 204 are meshed and connected, the driven shaft 203 rotates synchronously, and the driven shaft 203 drives the reel 205 to rotate to reel the charging line 4, so as to prevent the charging line 4 from being scattered on the ground, thereby improving the service life of the charging line 4:

[0026] A cleaning mechanism 3 is provided inside the shell 5. The cleaning mechanism 3 includes a fixed plate 301. Two fixed plates 301 are provided. Both fixed plates 301 are fixedly connected to the inner wall of the shell 5. A roller 302 is rotatably installed on the fixed plate 301. The roller 302 contacts the charging line 4. A brush 303 is fixedly connected to the outer side of the roller 302. A collecting box 304 is slidably installed on the shell 5. A handle 305 is fixedly connected to the outer side of the collecting box 304. By providing the cleaning mechanism 3, when the charging line is retracted and released, the charging line 4 drives the roller 302 to rotate, and the roller 302 drives the brush 303 to rotate. The brush 303 brushes off the dust and impurities attached to the outer skin of the charging line 4, which is convenient for cleaning the charging line 4. The brushed dust and impurities fall into the collecting box 304. The collecting box 304 is taken out regularly to pour out the dust.

The connecting rod 6 is used to limit the mounting frame 8 and the limiting wheel 9, so that they can only move up and down along the connecting rod 6, and the limiting plate 7 is used to limit the connecting rod 6 to prevent the connecting rod 6 from slipping off the shell 5;

[0028] A sponge pad 11 is provided on the shell 5, and the charging cable 4 passes through the sponge pad 11. The sponge pad 11 is used to protect the charging cable 4 so that the charging cable 4 does not directly contact the shell 5 when the cable is retracted or released, thereby preventing the surface of the charging cable 4 from being worn.

[0029] Specifically, the working process or working principle of the charging pile with automatic wire winding function is as follows: the car owner holds the charging head and presses the control button on the charging pile body 1, the motor 201 drives the winding roller 205 to release the wire, and the charging head is inserted into the charging port of the car for charging. After charging is completed, the motor 201 is driven, and the output end of the motor 201 drives the driving shaft 202 to rotate, and the driving shaft 202 drives the bevel gear 204 thereon to rotate. Since the two bevel gears 204 are meshed and connected, the driven shaft 203 rotates synchronously, and the driven shaft 203 drives the winding roller 205 to rotate to wind up the charging wire 4, thereby preventing the charging wire 4 from being scattered on the ground and improving the service life of the charging wire 4.

[0030] By setting up the cleaning mechanism 3, the charging cable 4 will drive the roller 302 to rotate when the cable is retracted and released, and the roller 302 will drive the brush 303 to rotate. The brush 303 will brush off the dust and impurities attached to the outer skin of the charging cable 4, so that the charging cable 4 can be cleaned easily. The dust and impurities brushed off will fall into the collection box 304, and the collection box 304 will be taken out regularly to pour out the dust. The sponge pad 11 is used to protect the charging cable 4, so that when the cable is retracted and released, the charging cable 4 will not directly contact the shell 5, so as to prevent the surface of the charging cable 4 from being worn.
