[0002] A charging pile is a device that provides electrical energy for electric vehicles (including pure electric vehicles and plug-in hybrid vehicles). Its core function is to charge the vehicle battery through a power input and output interface, supporting the operation of new energy vehicles. The modular integrated charging pile is one of them, and this kind of charging pile can dynamically adjust the power output according to needs, thereby improving the charging efficiency and equipment utilization rate; Chinese Patent CN215042191U discloses a modular dual-gun DC charging pile. By modularizing the design of various functions such as AC input, charging power module, and charging control part on the charging device, the functional module has a simple structure, a plug-in design, is easy to install, reduces operation and maintenance costs, and makes the equipment operate more stably. However, the prior art does not have a cable storage function, and the cables are directly hung outside the charging pile. When the charging pile is installed outdoors, the cables that are long-term exposed to the outside are easily affected by wind, rain, sun, and human factors, resulting in wear, aging, and even breakage of the cable outer skin, increasing the risk of short circuit and electric shock, thus triggering safety accidents. Moreover, during the charging process, the cables are directly dragged on the ground, which will cause dirt to stick to the cable surface and damage the cable, reducing the service life of the cable.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0019] Please refer to Figures 1-9 , a modular integrated dual-gun charging pile, including a cabinet body 1. Inside the cabinet body 1, there are sequentially arranged a charging power module 2, a charging control module 3, a charging cable 8 and a storage mechanism 4. The storage mechanism 4 includes a cable reel 41, a storage board 44 and a cleaning component 5. The cable reel 41 is installed at the bottom of the cabinet body 1 for winding the charging cable 8. The storage board 44 is installed on the side of the cabinet body 1 and is located above the cable reel 41. The storage board 44 can extend out from the side of the cabinet body 1. The cleaning component 5 includes a cleaning brush box 51 and a wiping box 6. The cleaning brush box 51 and the wiping box 6 are sequentially installed inside the storage board 44. A pair of brush rollers 53 are installed inside the cleaning brush box 51, and the brush rollers 53 can rotate inside the cleaning brush box 51. Two mounting frames 64 are symmetrically installed up and down inside the wiping box 6. A sponge roller 68 is installed inside the mounting frame 64. The outside of the mounting frame 64 is connected to a driving frame 65, and the driving frame 65 can push the mounting frame 64 to move in the vertical direction. The charging cable 8 is wound on the cable reel 41, and the head end of the charging cable 8 sequentially passes through the wiping box 6 and the cleaning brush box 51, passes through a pair of sponge rollers 68 and a pair of brush rollers 53 respectively, and is connected to the charging gun 81. The charging gun 81 is placed on the storage board 44. When storing the charging cable 8, the driving frame 65 drives the mounting frame 64 to approach the charging cable 8, so that the sponge roller 68 presses on the charging cable 8 to wipe the charging cable 8.

[0020] Among them, during use, in the initial state, the cable reel 41 winds the entire charging cable 8 into the cabinet body 1. The storage board 44 drives the charging gun 81 to retract into the cabinet body 1. At this time, the two driving frames 65 in the wiping box 6 are respectively located at the uppermost and lowermost ends of the wiping box 6, separating the sponge roller 68 from the charging cable 8. When charging is required, first, the storage board 44 is pulled out from the cabinet body 1. Subsequently, the charging gun 81 is removed from the storage board 44, and an appropriate length of the charging cable 8 is pulled out so that the charging gun 81 can be inserted into the charging port of the vehicle. Among them, the charging control module 3 is assembled from 4 300A DC contactors, 2 150A DC contactors, a wiring row, a control board and other devices, realizing the power distribution, safety protection and charging process control of the charging pile. When the vehicle completes charging and the charging gun 81 is pulled out, the cable reel 41 starts to rotate to wind up the pulled-out charging cable 8. During this process, the charging cable 8 passes through the cleaning box 51 and the wiping box 6 in sequence, and will be wound onto the cable reel 41 only after being cleaned by the cleaning box 51 and wiped. When the cable reel 41 starts to wind up the charging cable 8, a pair of brush rollers 53 in the cleaning box 51 rotate to clean the dirt attached to the surface of the charging cable 8. At the same time, the two driving frames 65 in the wiping box 6 synchronously push the mounting frame 64 towards the charging cable 8, pressing the sponge roller 68 onto the charging cable 8 so that the upper and lower sponge rollers 68 are in contact with each other, wrapping the charging cable 8. The charging cable 8 wound by the cable reel 41 drives the two sponge rollers 68 to rotate through friction, thereby wiping off the remaining dirt on the charging cable 8. Especially in rainy days, the sponge roller 68 can dry the rainwater attached to the charging cable 8, so that the charging cable 8 can be cleanly stored in the cabinet body 1, improving the service life of the charging cable 8. When the charging cable 8 is about to be completely retracted into the cabinet body 1, the charging gun 81 is placed back on the storage board 44 to fix the charging gun 81 on the storage board 44. As the cable reel 41 winds up the remaining charging cable 8, the remaining charging cable 8 will pull the storage board 44 to retract into the cabinet body 1 while being stored in the cabinet body 1, automatically taking the charging gun 81 into the cabinet body 1 as well. At this time, the cable reel 41 stops winding, the brush rollers 53 in the cleaning box 51 stop rotating, and the two driving frames 65 in the wiping box 6 drive the mounting frame 64 thereon away from the charging cable 8, returning to the uppermost and lowermost ends of the wiping box 6 respectively, separating the sponge roller 68 from the charging cable 8, waiting for the next use.

[0021] The difference from the above embodiments is that a fixing frame 11 is fixedly installed in the cabinet body 1. The fixing frame 11 divides the interior of the cabinet body 1 into multiple spaces. Among them, the spaces at the lower end of the cabinet body 1 are successively a cleaning bin 12 and a storage bin 13. A side opening 121 is formed on the side wall of the cleaning bin 12, and the side opening 121 communicates the cleaning bin 12 with the outside. A slideway 122 is formed at the bottom of the cleaning bin 12. A notch is formed between the cleaning bin 12 and the storage bin 13, and the cleaning bin 12 communicates with the storage bin 13 through the notch.

[0022] The difference from the above embodiments is that a handle 441 is fixedly connected to the outside of the storage board 44. A fixing clip 442 and a docking port 443 are successively fixedly connected to the inside of the storage board 44. The fixing clip 442 and the docking port 443 correspond to the gun body and the gun head of the charging gun 81 respectively. A connecting rod 444 is fixedly connected to the bottom of the storage board 44, and the connecting rod 444 is slidably installed in the slideway 122.

[0023] Among them, the storage board 44 can be pulled out from the side opening 121 through the handle 441. When placing the charging gun 81 on the storage board 44, first insert the gun head of the charging gun 81 into the docking port 443 to make the gun head clamped in the docking port 443, and then clamp the gun body of the charging gun 81 into the fixing clip 442, so that the charging gun 81 is fixed on the storage board 44. When taking out the charging gun 81, lift the gun body of the charging gun 81 from the fixing clip 442 and pull out the gun head of the charging gun 81 from the docking port 443. The storage board 44 slides into or out of the cleaning bin 12 through the cooperation of the connecting rod 444 and the slideway 122.

[0024] The difference from the above embodiments is that the upper end of the cleaning box 51 is fixedly connected to the top of the cleaning bin 12. A pair of transmission rods 52 are rotatably installed in the cleaning box 51. A brush roller 53 is fixedly connected to the lower end of each transmission rod 52. A plurality of bristles are evenly distributed on the circumferential side of the brush roller 53. The lower end of the brush roller 53 is rotatably connected to the bottom of the cleaning box 51. A pulley 54 is coaxially fixedly connected to the upper end of the transmission rod 52, and the two pulleys 54 are connected by a transmission belt 55.

[0025] The difference from the above embodiments is that a servo motor 56 is fixedly installed on the top of the cleaning box 51. The output shaft of the servo motor 56 is coaxially fixedly connected to one of the transmission rods 52. An opening is formed at the bottom of the cleaning box 51. A collection box 57 is arranged at the bottom of the cleaning box 51. A buckle 58 is fixedly installed on the outside of the collection box 57, and the collection box 57 is clamped to the bottom of the cleaning box 51 through the buckle 58.

[0026] Among them, when storing the charging cable 8, the servo motor 56 drives the brush roller 53 under one of the transmission rods 52 to rotate. At the same time, the transmission rod 52 drives the other transmission rod 52 to rotate through the transmission belt 55, so that a pair of brush rollers 53 rotate synchronously. The rotating brush rollers 53 brush off the dirt on the surface of the charging cable 8 through the bristles on them. The brushed-off dirt will fall into the collection box 57 at the bottom of the cleaning box 51. When the charging cable 8 is completely stored in the cabinet 1, the servo motor 56 stops working. During daily maintenance, the collection box 57 can be removed from the cleaning box 51 by opening the buckle 58. After removing the collected dirt, the collection box 57 is reinstalled on the cleaning box 51 through the buckle 58.

[0027] The difference from the above embodiment is that limiting columns 61 are fixedly connected to both sides inside the wiping box 6. A rotating shaft 62 is provided between two adjacent limiting columns 61. The rotating shaft 62 is fixedly connected to the side wall of the wiping box 6. The rotating shaft 62 is located in the middle of the wiping box 6. A transmission gear 63 is rotatably installed on the rotating shaft 62.

[0028] The difference from the above embodiment is that sliding grooves 641 are formed on both sides of the mounting frame 64. The sliding grooves 641 correspond to the limiting columns 61. The mounting frame 64 is slidably installed on the limiting columns 61 through the sliding grooves 641. A sponge roller 68 is rotatably installed inside the mounting frame 64. Push rods 651 are fixedly connected to both sides of the driving frame 65. The outside of the mounting frame 64 is slidably connected to the inside of the push rods 651. Among them, the top of the driving frame 65 located at the upper end of the wiping box 6 is fixedly connected to the output shaft of the electric push rod 69. The electric push rod 69 is fixedly installed on the top of the cleaning bin 12. A driving rack 652 is fixedly connected to one side of the push rod 651. The driving rack 652 on the push rod 651 at the lower part meshes with one side of the transmission gear 63 close to the cleaning box 51. The driving rack 652 on the push rod 651 at the upper part meshes with the other side of the transmission gear 63.

[0029] The difference from the above embodiment is that guide rods 66 are fixedly connected to both sides of the mounting frame 64 at the end facing the driving frame 65. The guide rods 66 slidably penetrate through the driving frame 65. A support spring 67 is sleeved on the guide rods 66. The support spring 67 abuts between the driving frame 65 and the mounting frame 64.

[0030] Among them, initially, the electric push rod 69 retracts its output shaft, so that the two drive frames 65 are respectively located at the uppermost and lowermost ends of the wiping box 6. At the same time, the supporting spring 67 pushes the mounting frame 64 away from the drive frame 65. At this time, the distance between the mounting frame 64 and the drive frame 65 is the largest. When the cable reel 41 winds up the charging cable 8, the electric push rod 69 extends its output shaft downward, pushing the drive frame 65 above the charging cable 8 downward. The drive rack 652 on the push rod 651 of the drive frame 65 drives the transmission gear 63 to rotate forward. The rotating transmission gear 63 drives the drive rack 652 on the other side to move upward, thereby pulling the drive frame 65 below the charging cable 8 upward, so that the two mounting frames 64 approach the charging cable 8. When the two sponge rollers 68 press on the charging cable 8, the electric push rod 69 continues to push the drive frame 65 above the charging cable 8 downward, so that the two sponge rollers 68 approach each other, wrap the slave cable, and compress the supporting spring 67, causing the mounting frame 64 to approach the drive frame 65 on the push rod 651, reducing the distance between the mounting frame 64 and the drive frame 65. When the charging cable 8 is completely stored in the cabinet 1, the electric push rod 69 retracts its output shaft, causing the drive frame 65 above the charging cable 8 to move upward back to the uppermost end of the wiping box 6. At the same time, the upward moving drive frame 65 drives the transmission gear 63 to rotate reversely through the drive rack 652 on it, driving the drive frame 65 below the charging cable 8 back to the lowermost end of the wiping box 6. During this process, the compressed supporting spring 67 resumes its deformation, pushing the mounting frame 64 and the drive frame 65 apart until the distance between the mounting frame 64 and the drive frame 65 reaches the maximum distance, and then the drive frame 65 pulls the sponge roller 68 pressing on the charging cable 8 away from the charging cable 8. Embodiment 2

[0031] The difference from the above embodiment is that guide wheels 7 are fixedly connected to the side walls of the cleaning bin 12 and the storage bin 13. When the charging cable 8 enters the cleaning bin 12 from the storage bin 13, it bypasses the guide wheels 7 in sequence.

[0032] Among them, the guide wheels 7 provide guidance for the charging cable 8, preventing the charging cable 8 from becoming scattered during the winding or extraction process. Embodiment 3

[0033] The difference from the above embodiment is that the storage mechanism 4 further includes a drive motor 43. The drive motor 43 is fixedly installed in the storage chamber. The cable reel 41 is coaxially and fixedly installed on the rotating shaft 42. One end of the rotating shaft 42 is rotatably connected to the fixed frame 11, and the other end of the rotating shaft 42 is fixedly connected to the output shaft of the drive motor 43. The tail end of the charging cable 8 is fixedly connected to the rotating shaft 42.

[0034] Among them, when it is necessary to store the charging cable 8, the drive motor 43 drives the cable reel 41 to rotate to wind up the charging cable 8.

[0035] Working principle: During use, in the initial state, the cable reel 41 winds the entire charging cable 8 into the cabinet body 1. The storage board 44 drives the charging gun 81 to retract into the cabinet body 1. At this time, the two driving frames 65 in the wiping box 6 are respectively located at the uppermost and lowermost ends of the wiping box 6, separating the sponge roller 68 from the charging cable 8. When charging is required, first, the storage board 44 is pulled out from the cabinet body 1, and then the charging gun 81 is removed from the storage board 44, and an appropriate length of the charging cable 8 is pulled out so that the charging gun 81 can be inserted into the charging port of the vehicle. Among them, the charging control module 3 is composed of 4 300A DC contactors, 2 150A DC contactors, a wiring row, a control board and other devices, realizing the power distribution, safety protection and charging process control of the charging pile. When the vehicle finishes charging and the charging gun 81 is pulled out, the cable reel 41 starts to rotate to wind up the pulled-out charging cable 8. During this process, the charging cable 8 passes through the cleaning box 51 and the wiping box 6 in sequence, and will be wound onto the cable reel 41 only after being cleaned by the cleaning box 51 and wiped. When the cable reel 41 starts to wind up the charging cable 8, the servo motor 56 on the cleaning box 51 drives the brush roller 53 under one of the transmission rods 52 to rotate. At the same time, this transmission rod 52 drives the other transmission rod 52 to rotate through the transmission belt 55, so that a pair of brush rollers 53 rotate synchronously. The rotating brush rollers 53 brush off the dirt on the surface of the charging cable 8 through the bristles on them, and the brushed-off dirt will fall into the collection box 57 at the bottom of the cleaning box 51; At the same time, the electric push rod 69 on the wiping box 6 extends the output shaft downward, pushing the driving frame 65 above the charging cable 8 to move downward. The driving rack 652 on the push rod 651 of this driving frame 65 drives the transmission gear 63 to rotate forward. The rotating transmission gear 63 drives the driving rack 652 on the other side to move upward, thereby pulling the driving frame 65 below the charging cable 8 to move upward, so that the two mounting frames 64 approach the charging cable 8. When the two sponge rollers 68 press on the charging cable 8, the electric push rod 69 continues to push the driving frame 65 above the charging cable 8 downward, so that the two sponge rollers 68 approach each other, wrap the driven cable, and compress the support spring 67, so that the mounting frame 64 approaches the driving frame 65 on the push rod 651, reducing the distance between the mounting frame 64 and the driving frame 65. The charging cable 8 wound by the cable reel 41 drives the two sponge rollers 68 to rotate through friction, thereby wiping off the remaining dirt on the charging cable 8. Especially in rainy days, the sponge rollers 68 can dry the rainwater attached to the charging cable 8, so that the charging cable 8 can be cleanly stored in the cabinet body 1, improving the service life of the charging cable 8. When the charging cable 8 is about to be completely retracted into the cabinet body 1, the charging gun 81 is placed back on the storage board 44 to fix the charging gun 81 on the storage board 44, and the cable reel 41 winds up the remaining charging cable 8; While the remaining charging cable 8 is being stored in the cabinet body 1, it also pulls the storage board 44 to retract into the cabinet body 1, automatically taking the charging gun 81 into the cabinet body 1 as well. At this time, the wire reel 41 stops winding, the brush roller 53 in the cleaning box 51 stops rotating, and the electric push rod 69 on the wiping box 6 retracts its output shaft, causing the driving frame 65 located above the charging cable 8 to move upward back to the uppermost end of the wiping box 6. At the same time, the upward moving driving frame 65 drives the transmission gear 63 to rotate in the reverse direction through the driving rack 652 thereon, driving the driving frame 65 located below the charging cable 8 back to the lowermost end of the wiping box 6. During this process, the compressed support spring 67 restores its deformation, pushing the mounting frame 64 and the driving frame 65 apart until the distance between the mounting frame 64 and the driving frame 65 reaches the maximum distance, then the driving frame 65 pulls the sponge roller 68 pressing on the charging cable 8 away from the charging cable 8, waiting for the next use. During daily maintenance, the collection box 57 can be removed from the cleaning box 51 by opening the buckle 58. After removing the dirt collected therein, the collection box 57 is reinstalled on the cleaning box 51 through the buckle 58.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
