Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and specifically to a charging pile with multi-mode charging function. Background Technology

[0002] Multi-mode charging piles are comprehensive charging devices that support multiple charging modes, power input methods, and energy management strategies. They support photovoltaic modules to directly charge power batteries or energy storage batteries, realizing green energy utilization. By using energy storage batteries as an intermediate medium, they balance the grid load and improve energy utilization. They automatically switch power sources according to demand (such as photovoltaic priority and grid supplementation) to optimize the energy structure. The same device supports AC slow charging and DC fast charging to adapt to the needs of different vehicles. Equipped with multiple charging interfaces, they can provide charging services for multiple electric vehicles simultaneously.

[0003] In existing technologies, due to the environmental adaptability and long-term reliability issues of charging cables for outdoor multi-mode charging piles, traditional outdoor charging piles' charging cables are directly exposed to harsh environments such as sunlight and ultraviolet radiation, rain immersion, drastic temperature fluctuations, and humid air. This leads to accelerated aging and cracking of the insulation layer and oxidation and corrosion of the metal conductors, which can easily cause safety hazards such as leakage, short circuits, and even fires. At the same time, traditional solutions rely on static sealing structures (such as rubber plugs), which are difficult to meet the protection requirements when the cable is in dynamic motion, and long-term exposure will still cause the seals to age and fail. Therefore, charging cables are a weak link in protection in complex outdoor environments. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a charging pile with multi-mode charging functionality to solve the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A charging pile with multi-mode charging function includes a multi-mode charging pile. Protective shells are fixedly installed on the exterior of the charging gun compartments on both sides of the multi-mode charging pile. Two mounting brackets are fixedly installed on the side of each protective shell near the multi-mode charging pile, and the mounting brackets are fixedly installed to the multi-mode charging pile. A protection component is disposed on the top surface of the protective shells for protecting the connection cables between the multi-mode charging pile and the charging guns of the multi-mode charging pile. The protection component includes two telescopic corrugated pipes, which are respectively fixedly installed on the top surfaces of the two protective shells. The telescopic corrugated pipes are connected to the multi-mode charging... The charging gun cable is movably connected. The top surface of the protective shell has a movable opening, and the side of the protective shell closest to the multi-mode charging pile has a cable inlet. The movable opening and the cable inlet are movably connected to the cable of the multi-mode charging pile. The side of the protective shell away from the multi-mode charging pile has an observation opening, and a transparent plate is movably engaged inside the observation opening. The interior of the protective shell is equipped with a cable pulling assembly for winding and unwinding the charging gun cable of the multi-mode charging pile. The bottom surface of the interior of the protective shell is equipped with a moisture-absorbing assembly for keeping the interior of the protective shell dry. The interior of the telescopic corrugated tube is equipped with a blocking assembly for preventing rainwater from entering the interior of the protective shell.

[0007] By adopting the above technical solution and using the protective shell, workers can pass the cable of the multi-mode charging pile charging gun through the inlet hole into the interior of the protective shell. Then, the end of the cable connected to the charging gun is passed out through the movable port inside the protective shell. At this point, the head and tail of the charging cable are connected to the charging gun and the main body of the multi-mode charging pile, respectively, while the remaining part remains inside the protective shell. At the same time, after the front end of the cable is moved out of the protective shell, it enters the interior of the telescopic corrugated tube, thus protecting the cable by wrapping it inside the telescopic corrugated tube. Meanwhile, most of the cable remains inside the protective shell, which facilitates the protection of the charging cable of the multi-mode charging pile and reduces the risk of cable breakage and safety hazards caused by environmental factors such as sun and rain in the outdoor environment.

[0008] Preferably, the cable pulling assembly includes: a take-up roller rotatably connected inside the protective housing; a winding hole is formed on the outer circular wall of the take-up roller; a ring gear is movably sleeved on the outer circular wall of the winding hole; a mounting plate is fixedly sleeved inside the ring gear; a movable hole is formed at one end of the mounting plate, which is movably sleeved with the take-up roller; a limit ring is fixedly installed at one end of the ring gear; an annular groove is formed on one side of the inner side of the protective housing, and the limit ring is movably sleeved with the annular groove; an arc-shaped groove is formed at one end of the mounting plate; and the take-up roller is close to the mounting plate. A fixing block is fixedly installed at one end of the device. A contraction hole is formed on the top surface of the fixing block. Two sliding grooves are formed on the inner circular wall of the contraction hole. Two blocking posts are movably sleeved inside the contraction hole. A flat groove is formed on the outside of the blocking posts. A spring is fixedly installed between the two blocking posts. Two sliders are fixedly installed on the outer circular wall of the blocking posts. The sliders are slidably connected to the sliding grooves. A spur gear is provided inside the protective shell. The spur gear meshes with the ring gear. A servo motor is provided inside the protective shell. The drive shaft of the servo motor is fixedly installed with the spur gear.

[0009] By adopting the above technical solution, after the cable connecting the multi-mode charging pile to the charging gun is placed inside the protective shell via the set take-up roller, it is first passed through the inside of the cable winding hole. Then, by rotating the take-up roller, the cable can be wound around the surface of the take-up roller. When the user uses the charging gun and pulls the cable, with continuous pulling, the cable will loosen from the surface of the take-up roller, causing the take-up roller to rotate. At this time, the take-up roller will drive the fixing block and the blocking post to rotate clockwise inside the arc-shaped groove. Since the arc-shaped groove has a radial arc structure, during the clockwise rotation, the top surface of the blocking post will continuously press against the inner circular wall of the arc-shaped groove, thus causing the inner circular wall of the arc-shaped groove to... The surface will press against the two barrier posts, causing them to move closer together and compress the spring. At this time, the take-up roller can only rotate clockwise to achieve the function of unwinding the cable. When the user finishes charging, the servo motor is used simultaneously. The servo motor's drive shaft rotates clockwise, which drives the spur gear to rotate. The spur gear then meshes with the ring gear to rotate, allowing the ring gear to rotate counterclockwise. The ring gear then drives the mounting plate to rotate counterclockwise. When the protruding part of the arc groove contacts the barrier post, the compression of the inner wall of the protruding part of the arc groove causes the mounting plate to drive the barrier post, the fixing block, and the take-up roller to rotate counterclockwise synchronously. The counterclockwise rotation of the take-up roller can rewind the cable.

[0010] Preferably, the moisture-absorbing component includes: a support shell, the support shell being fixedly installed on the inner bottom surface of the protective shell, the servo motor being fixedly sleeved with the support shell, a water filter plate being fixedly installed inside the support shell, a plurality of air vents being opened on one side of the support shell, and a door panel being movably snapped into the inside of the support shell.

[0011] By adopting the above technical solution and using the set support shell, the staff can put a desiccant such as a molecular sieve on the top surface of the filter plate. When the humidity inside the protective shell increases, it can absorb the moisture inside the protective shell and concentrate it, thereby making it easier to maintain a dry and clean environment inside the protective shell.

[0012] Preferably, a plurality of support columns are fixedly installed on the inner top surface of the protective shell, a cleaning block is fixedly installed on the bottom surface of the support columns, a water-wiping cloth is fixedly installed on one side of the cleaning block, the cleaning block is semi-circular, and a plurality of the cleaning blocks form a ring.

[0013] By adopting the above technical solution, the cable will pass between several wiping cloths when it is pulled out of the protective shell, and then the cable surface will come into contact with the wiping cloths, which makes it easy to wipe the surface of the cable. This makes it easy to wipe the cable surface when it rains or when there is dirt on the cable surface, and prevents water stains or dirt from being rolled up in the middle of the cable coil during the winding process.

[0014] Preferably, the blocking assembly includes: a water-blocking ring, which is fixedly sleeved on the inner circular wall of the telescopic corrugated pipe. The bottom surface of the water-blocking ring has several reserved grooves. A movable column is fixedly installed inside the reserved grooves. A waterproof plate is movably sleeved inside the reserved grooves. A torsion spring is movably sleeved on the outer circular wall of the movable column. A rotating hole is opened on one side of the waterproof plate, and the rotating hole is movably sleeved with the movable column.

[0015] By adopting the above technical solution, and through the waterproof plates, when the cable passes through the inside of the telescopic corrugated pipe, it will emerge from the middle of the water-blocking ring. At the same time, the cable will be between several waterproof plates. When the user needs a longer cable and the telescopic corrugated pipe cannot be extended further, the user can continue to pull the cable, and the telescopic corrugated pipe will not extend further. At this time, the cable moves between several waterproof plates, and through the friction generated when the cable surface contacts the waterproof plate, the waterproof plate will rotate in the direction of cable pulling. When the cable stops rotating, the rebound ability of the torsion spring will make the waterproof plate tightly adhere to the surface of the cable, thereby preventing rainwater from flowing into the interior of the protective shell along the cable when using the charging gun in rainy weather.

[0016] Preferably, absorbent cotton is fixedly installed on the top surface of the water-blocking ring.

[0017] By adopting the above technical solution, water stains flowing to the water-blocking ring can be absorbed.

[0018] Preferably, a rain shield is fixedly installed on one side of the protective shell, a proximity sensor is fixedly installed on the bottom surface of the rain shield, and a PLC controller is fixedly installed on one side of the support shell. The PLC controller is electrically connected to the servo motor and the proximity sensor.

[0019] By adopting the above technical solution, and through the proximity sensor, when the user puts the charging gun into the charging gun compartment after charging, the charging gun will pass through the inside of the protective shell. The proximity sensor will then detect the proximity of the charging gun and transmit the signal to the PLC controller. Subsequently, the PLC controller will control the servo motor to start, so that the used cable can be wound up. The user only needs to put the charging gun back, and no additional operation is required. The cable can be wound up automatically.

[0020] Preferably, a humidity sensor is fixedly installed on the inner top surface of the protective shell, and the humidity sensor is electrically connected to the PLC controller. An alarm light is fixedly installed on the top surface of the multi-mode charging pile, and the alarm light is electrically connected to the PLC controller.

[0021] By adopting the above technical solution, and through the set alarm light, when the humidity inside the charging gun compartment is high, the humidity sensor will transmit a signal to the PLC controller, and then the PLC controller will control the alarm light to light up, reminding the user that there is a lot of moisture in the charging gun and that it needs to be wiped before use to ensure safety.

[0022] In summary, the present invention has the following main beneficial effects:

[0023] 1. This invention achieves cable storage and standardized wiring through the combination of a protective shell and a telescopic corrugated tube. The protective shell covers the main body of the cable, and the telescopic corrugated tube wraps the exposed part, providing double protection against external environmental corrosion. The corrugated tube can be flexibly adjusted with the cable stretching and retracting to adapt to the cable length requirements in different usage scenarios, reducing the risk of physical damage to the cable due to long-term exposure, ensuring the safety of the charging process, thereby reducing safety hazards such as leakage and short circuit caused by cable damage, improving system reliability, and effectively isolating environmental factors such as ultraviolet rays and humidity, thus slowing down the aging of the cable.

[0024] 2. This invention utilizes the cooperation of the barrier post and the arc-shaped groove, combined with a spring clamping mechanism, to ensure that the take-up roller can only rotate clockwise, achieving safe cable unwinding. A servo motor drives a ring gear and a spur gear transmission, causing the take-up roller to rotate counterclockwise, thus winding the cable. The radial design of the arc-shaped groove guides the movement trajectory of the barrier post, ensuring the smoothness and stability of the unwinding and take-up process. The unidirectional unwinding mechanism prevents the cable from becoming disorderly and loose, reducing the risk of tripping or tangling. Automatic cable unwinding prevents the cable from being exposed, reducing the risk of electric shock. Orderly unwinding and take-up reduces cable bending fatigue and delays aging. The protective shell isolates the cable from environmental factors, preventing corrosion and damage.

[0025] 3. This invention provides a stable mounting carrier for the filter plate and desiccant through a support shell. The molecular sieve and other desiccants on the surface of the filter plate actively absorb moisture from the air inside the protective shell. Through physical adsorption, the dispersed water vapor is gathered to the area where the desiccant is located, which facilitates centralized treatment, reduces the humidity inside the protective shell, and prevents problems such as short circuits and corrosion of cables and electrical components caused by moisture. The dry environment reduces the risk of mold growth, avoids potential faults caused by decreased insulation performance, effectively inhibits the corrosion of metal parts and material aging, and extends the service life of the charging pile and its internal components.

[0026] 4. This invention directly removes water stains, dust, and debris from the cable surface by utilizing the frictional contact between the wiping cloth and the cable. The cleaning is completed simultaneously during the cable pulling process, without the need for additional operation steps. It prevents contaminants carried by the cable from entering the winding state, avoids impurities remaining in the cable winding gaps, and ensures the surface cleanliness of the cable before and after use in rainy or snowy weather or harsh working conditions. It reduces the risk of metal corrosion caused by water stains, extends the service life of the cable, prevents short circuits caused by conductive particles in the stains, or fire risks caused by the accumulation of organic matter, and prevents impurities from mixing into the cable winding structure, reducing the probability of jamming or wear during subsequent cable unwinding.

[0027] 5. This invention automatically adjusts the position of the waterproof plate as the cable moves, always wrapping the cable surface to form a waterproof barrier of variable length. The friction between the cable and the waterproof plate drives the waterproof plate to rotate in one direction, and the torsion spring achieves reset, adapting to different tension states. The tight fit between the waterproof plate and the cable blocks the path of rainwater seeping into the protective shell along the cable surface. The torsion spring provides rebound force, allowing the waterproof plate to automatically return to its initial fit when no external force is applied, maintaining the seal. This significantly reduces the risk of rainwater or other liquids seeping into the protective shell along the cable, ensuring the safety of internal electrical components. It can still operate stably in heavy rain or high humidity scenarios, avoiding charging interruptions or malfunctions caused by water ingress.

[0028] 6. This invention uses a proximity sensor to monitor in real time whether the charging gun is accurately placed in the charging gun compartment, providing precise position feedback. The physical proximity signal is converted into an electrical signal and transmitted to the PLC controller for logic processing. The PLC controller analyzes the sensor signal and automatically starts the servo motor to execute the cable winding command, achieving a seamless connection between the charging gun returning to its position and the cable winding, forming a complete automated operation closed loop. No additional operation is required from the user. After the charging gun returns to its position, the cable winding is automatically completed, simplifying the operation process, avoiding the cable being exposed, reducing the risk of tripping, wear, or accidental contact, and automatic winding prevents the cable from being in a stretched state for a long time, reducing fatigue damage and extending the service life of the cable and charging pile.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A charging pile with multi-mode charging function includes a multi-mode charging pile 1. Protective shells 2 are fixedly installed on the outside of the charging gun compartments on both sides of the multi-mode charging pile 1. Protective shells 3 are respectively provided on both sides of the multi-mode charging pile 1. Two mounting brackets 4 are fixedly installed on the side of the protective shell 3 near the multi-mode charging pile 1. The mounting brackets 4 are fixedly installed with the multi-mode charging pile 1. A protective component is provided on the top surface of the protective shell 3 for protecting the connection cable between the multi-mode charging pile 1 and the charging gun of the multi-mode charging pile 1. The protective component includes two telescopic corrugated tubes 5. The two telescopic corrugated tubes 5 are respectively fixedly installed on the top surface of the two protective shells 3. The telescopic corrugated tubes 5 are movably connected to the cable of the charging gun of the multi-mode charging pile 1. An opening 6 is provided on the top surface of the protective shell 3. An inlet hole 7 is provided on the side of the protective shell 3 near the multi-mode charging pile 1. The opening 6 and the inlet hole 7 are movably connected to the cable of the multi-mode charging pile 1. An observation port 32 is provided on the side of the protective shell 3 away from the multi-mode charging pile 1. A transparent plate 33 is movably snapped into the inside of the observation port 32.

[0043] By setting up the protective shell 3, staff can introduce the cable of the charging gun of the multi-mode charging pile 1 into the protective shell through the inlet hole 7. After the cable is connected to the charging gun, its free end is led out of the protective shell through the movable port 6. At this time, the two ends of the cable are stably connected to the charging gun and the charging pile body respectively, while the middle section is orderly stored inside the protective shell. When the front end of the cable extends out of the protective shell, it is immediately inserted into the telescopic corrugated tube 5 to form a double-layer protective structure. The main body of the cable is shielded by the protective shell, and the exposed part is wrapped by the telescopic corrugated tube. This design achieves all-round protection for the charging cable, significantly reducing the risk of corrosion of the cable by natural factors such as sun exposure and rain in the outdoor environment, thereby avoiding safety hazards caused by cable aging and cracking.

[0044] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The protective shell 3 has an internal cable pull assembly for winding and unwinding the charging gun cable of the multi-mode charging pile 1. The cable pull assembly includes a take-up roller 8, which is rotatably connected inside the protective shell 3. A winding hole 9 is formed on the outer circular wall of the take-up roller 8. A ring gear 10 is movably sleeved on the outer circular wall of the winding hole 9. A mounting plate 11 is fixedly sleeved inside the ring gear 10. One end of the mounting plate 11 has a movable hole 15, which is movably sleeved with the take-up roller 8. A limit ring 12 is fixedly installed on one end of the ring gear 10. An annular groove 13 is formed on one side of the interior of the protective shell 3, and the limit ring 12 is movably sleeved with the annular groove 13. One end of the mounting plate 11 has an arc-shaped groove 14. A fixing block 16 is fixedly installed at one end of the roller 8 near the mounting plate 11. A contraction hole 17 is opened on the top surface of the fixing block 16. Two sliding grooves 18 are opened on the inner circular wall of the contraction hole 17. Two blocking posts 19 are movably sleeved inside the contraction hole 17. A flat groove 20 is opened on the outside of the blocking posts 19. A spring 21 is fixedly installed between the two blocking posts 19. Two sliders 22 are fixedly installed on the outer circular wall of the blocking posts 19. The sliders 22 are slidably connected to the sliding grooves 18. A spur gear 23 is provided inside the protective shell 3. The spur gear 23 is meshed with the ring gear 10. A servo motor 24 is provided inside the protective shell 3. The drive shaft of the servo motor 24 is fixedly installed with the spur gear 23.

[0045] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 11A rain shield 40 is fixedly installed on one side of the protective shell 2, and a proximity sensor 41 is fixedly installed on the bottom surface of the rain shield 40. A PLC controller is fixedly installed on one side of the support shell 25. The PLC controller is electrically connected to the servo motor 24 and the proximity sensor 41.

[0046] By setting up the take-up roller 8, after the charging gun cable of the multi-mode charging pile 1 is placed inside the protective shell 3, it needs to be passed through the winding hole 9 first. Then, by rotating the take-up roller 8, the cable can be evenly wound around its surface. When the user pulls the charging gun, the cable gradually loosens from the surface of the take-up roller and drives the take-up roller to rotate clockwise. At this time, the take-up roller drives the fixing block 16 and the blocking post 19 to rotate clockwise synchronously along the arc groove 14. Since the arc groove adopts a radial arc structure, the top of the blocking post is always in contact with the inner wall of the arc groove. Under the pressure of the inner wall, the two blocking posts move closer to each other and compress the spring 21, thereby limiting the movement of the charging gun cable. The take-up roller can only rotate clockwise in one direction to achieve controllable cable feeding. After charging is completed, the servo motor 24 starts, and its drive shaft rotates clockwise to drive the spur gear 23 to rotate, which in turn meshes with the ring gear 10 to rotate counterclockwise. The ring gear drives the mounting plate 11 to rotate counterclockwise synchronously. When the protruding part of the arc groove contacts the blocking post 19, the mounting plate drives the blocking post, the fixing block and the take-up roller to rotate counterclockwise synchronously through the squeezing action of the inner wall, thus completing the cable winding. By using the cooperation between the blocking post and the arc groove, combined with the spring clamping mechanism, it is ensured that the take-up roller can only rotate clockwise to achieve safe cable feeding.

[0047] By setting a proximity sensor 41, when the user finishes charging and puts the charging gun back into the charging gun compartment, the charging gun needs to pass through the protective shell 2 to enter the designated position. At this time, the proximity sensor 41 can accurately sense the arrival signal of the charging gun and then transmit the signal to the PLC controller. After receiving the signal, the PLC controller drives the servo motor 24 to start and automatically complete the cable winding operation. This design allows the user to trigger the fully automated operation simply by putting the charging gun back into the compartment, without any additional intervention, which significantly improves the ease of use.

[0048] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The bottom surface of the protective shell 3 is provided with a moisture-absorbing component for keeping the inside of the protective shell 3 dry. The moisture-absorbing component includes a support shell 25, which is fixedly installed on the bottom surface of the protective shell 3. The servo motor 24 is fixedly sleeved with the support shell 25. A water filter plate 26 is fixedly installed inside the support shell 25. Several ventilation holes 27 are opened on one side of the support shell 25. A door panel 28 is movably snapped into the inside of the support shell 25.

[0049] By setting up the support shell 25, workers can orderly lay desiccants such as molecular sieves on the top surface of the filter plate 26. When the humidity inside the protective shell 3 increases, the desiccant can efficiently adsorb water vapor in the environment, causing moisture to concentrate in a specific area, thereby continuously maintaining a dry and clean environment inside the protective shell.

[0050] refer to Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 The protective shell 3 has several support columns 29 fixedly installed on its inner top surface. A cleaning block 30 is fixedly installed on the bottom surface of the support column 29. A water-wiping cloth 31 is fixedly installed on one side of the cleaning block 30. The cleaning block 30 is semi-circular. Several cleaning blocks 30 form a ring. The telescopic corrugated pipe 5 is equipped with a blocking component to prevent rainwater from entering the protective shell 3. The blocking component includes a water-blocking ring 34. The water-blocking ring 34 is fixedly sleeved on the inner circular wall of the telescopic corrugated pipe 5. Several reserved grooves 35 are opened on the bottom surface of the water-blocking ring 34. A movable column 36 is fixedly installed inside the reserved groove 35. A waterproof plate 37 is movably sleeved inside the reserved groove 35. A torsion spring is movably sleeved on the outer circular wall of the movable column 36. A rotating hole 38 is opened on one side of the waterproof plate 37. The rotating hole 38 is movably sleeved with the movable column 36. A water-absorbing cotton 39 is fixedly installed on the top surface of the water-blocking ring 34.

[0051] By setting up the wiping cloth 31, when the cable is pulled out from inside the protective shell 3, it needs to pass through the cleaning area formed by multiple wiping cloths in sequence. The cable surface is in close contact with the wiping cloth, which can effectively remove rainwater, stains and impurities from the cable surface. It is especially suitable for rainy days or scenarios where the cable is dirty. This design avoids bringing water stains, dirt and other contaminants into the cable winding center during the cable winding process, ensuring the cleanliness of the cable after storage.

[0052] By setting up waterproof plates 37, when the cable passes through the telescopic corrugated pipe 5 and exits through the center of the water-blocking ring 34, the cable is guided into the protective channel formed by multiple waterproof plates. If the user needs to further extend the cable and the telescopic corrugated pipe is fully extended, the cable will slide between the waterproof plates 37 when the cable is pulled. During this process, the cable and the surface of the waterproof plate generate friction, which drives the waterproof plate to rotate flexibly in the direction of the pulling force. When the cable stops moving, the rebound force of the torsion spring causes the waterproof plate to fit tightly against the surface of the cable. This design can effectively prevent rainwater from flowing into the interior of the protective shell 3 along the surface of the cable when used in rainy weather, ensuring the safety of the equipment.

[0053] refer to Figure 1 , Figure 2 and Figure 3A humidity sensor 42 is fixedly installed on the top surface inside the protective shell 2. The humidity sensor 42 is electrically connected to the PLC controller. An alarm light 43 is fixedly installed on the top surface of the multi-mode charging pile 1. The alarm light 43 is electrically connected to the PLC controller.

[0054] By setting alarm light 43, when the humidity inside the charging gun compartment exceeds the safety threshold, humidity sensor 42 collects ambient humidity data in real time and transmits it to the PLC controller. After the PLC controller analyzes the signal, it drives alarm light 43 to light up, thereby warning the user that there may be a lot of moisture residue in the charging gun and that it needs to be wiped or dried before use, so as to ensure electrical safety. The eye-catching light prompts increase the user's attention to potential risks and encourage them to take initiative to deal with them.

[0055] Working principle: Please refer to Figures 1-11 As shown, with the protective shell 3 in place, the operator passes the cable of the charging gun of the multi-mode charging pile 1 through the inlet hole 7, allowing the cable to enter the interior of the protective shell 3. Then, the end of the cable connected to the charging gun is passed out of the interior of the protective shell 3 through the movable port 6. At this time, the head and tail of the charging cable are connected to the charging gun and the main body of the multi-mode charging pile 1, respectively, while the remaining part remains inside the protective shell 3. At the same time, after the front end of the cable is moved out of the interior of the protective shell 3, it will enter the interior of the telescopic corrugated tube 5, thus protecting the cable by wrapping it inside the telescopic corrugated tube 5. Meanwhile, most of the cable remains inside the protective shell 3, which facilitates the protection of the charging cable of the multi-mode charging pile 1 and reduces the risk of cable breakage and safety hazards caused by environmental factors such as sun and rain in the outdoor environment.

[0056] After the cable connecting the charging gun to the multi-mode charging pile 1 is placed inside the protective shell 3 via the winding roller 8, it first passes through the inside of the winding hole 9. Then, rotating the winding roller 8 winds the cable around its surface. When the user uses the charging gun and pulls the cable, the cable will unwind from the surface of the winding roller 8, causing the winding roller 8 to rotate. At this time, the winding roller 8 will cause the fixing block 16 and the blocking post 19 to rotate clockwise inside the arc groove 14. Since the arc groove 14 has a radial arc structure, during the clockwise rotation, the top surface of the blocking post 19 will continuously press against the inner circular wall of the arc groove 14, causing the inner circular wall of the arc groove 14 to squeeze the two blocking posts 19. Two barrier posts 19 approach each other and compress spring 21. At this time, the take-up roller 8 can only rotate clockwise to achieve the function of unwinding the cable. When the user finishes charging, the servo motor 24 is used at the same time. The drive shaft of the servo motor 24 rotates clockwise, which drives the spur gear 23 to rotate. In turn, the spur gear 23 meshes with the ring gear 10 to rotate, which allows the ring gear 10 to rotate counterclockwise. Then the ring gear 10 drives the mounting plate 11 to rotate counterclockwise. When the protruding part of the arc groove 14 contacts the barrier post 19, the compression of the inner wall of the protruding part of the arc groove 14 can cause the mounting plate 11 to drive the barrier post 19, the fixing block 16 and the take-up roller 8 to rotate counterclockwise synchronously. The counterclockwise rotation of the take-up roller 8 can rewind the cable.

[0057] With the help of the wipers 31, when the cable is pulled out of the protective shell 3, it will pass between several wipers 31, and then the surface of the cable will come into contact with the wipers 31, which makes it easy to wipe the surface of the cable. This makes it easy to wipe the cable when it rains or when the surface of the cable is dirty, and prevents water stains or dirt from being rolled up in the middle of the cable coil during the winding process.

[0058] With the waterproof plates 37 in place, after the cable passes through the inside of the telescopic corrugated tube 5, it will emerge from the middle of the water-blocking ring 34. At the same time, the cable will be between several waterproof plates 37. When the user needs a longer cable and the telescopic corrugated tube 5 cannot be extended further, the user can continue to pull the cable, and the telescopic corrugated tube 5 will not continue to extend. At this time, the cable moves between several waterproof plates 37, and the friction generated when the cable surface contacts the waterproof plate 37 will cause the waterproof plate 37 to rotate in the direction of cable pulling. When the cable stops rotating, the rebound ability of the torsion spring will make the waterproof plate 37 stick tightly to the surface of the cable, thereby preventing rainwater from flowing into the interior of the protective shell 3 along the cable when using the charging gun in rainy weather.

[0059] When the user places the charging gun into the charging gun compartment after charging, the charging gun will pass through the inside of the protective shell 2. The proximity sensor 41 will then detect the proximity of the charging gun and transmit the signal to the PLC controller. The PLC controller will then control the servo motor 24 to start, so that the used cable can be wound up. The user only needs to put the charging gun back, and no additional operation is required. The cable can be wound up automatically.

[0060] When the humidity inside the charging gun compartment is high, the humidity sensor 42 will transmit a signal to the PLC controller via the alarm light 43. The PLC controller will then control the alarm light 43 to light up, reminding the user that there is a lot of moisture in the charging gun and that it needs to be wiped before use to ensure safety.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
