Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging piles, and specifically provides an antifreeze type charging pile for extremely cold regions. Background Art

[0002] In today's era of increasing popularity of electric vehicles, charging piles are important supply facilities for electric vehicles, and their performance and stability directly affect the user experience of electric vehicles. Especially in cold areas, the low temperature environment in winter brings many challenges to the use of charging piles, among which the antifreeze problem of charging cables is particularly prominent.

[0003] In the authorization announcement number CN220884113U, a car charging pile with an antifreeze function is disclosed. The charging pile only considers the antifreeze between the charging gun and the socket on the charging pile, but ignores the antifreeze protection of the charging cable.

[0004] In cold weather, the charging cable is pulled out for charging and is directly exposed to the outside. Snow and ice from the outside are likely to adhere directly to the outer surface of the charging cable. If the snow and ice are not cleaned in time, the charging cable will easily age at low temperatures. When charging is completed, the ice and snow attached to the cable are difficult to fall off by themselves and often need to be removed manually. If the snow and ice are not removed, the cable will be too heavy, making it inconvenient for users to put the cable and charging gun back, which will cause great inconvenience to users during actual use. At the same time, not cleaning the snow and ice will also reduce the service life and safety of the charging cable.

[0005] Therefore, the present invention proposes an antifreeze charging pile for extremely cold regions to make up for and improve the deficiencies of the prior art. Summary of the invention

[0019] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] The antifreeze type charging pile, through the antifreeze component, forms a protective layer on the outside of the charging cable by using the air bag sleeve filled with air when the charging cable is used in cold weather, which can not only prevent snow and ice from directly adhering to the outer surface of the charging cable, but also release the air inside the air bag sleeve after charging is completed, so that the ice and snow on the outer surface fall off, without the need to manually remove the snow and ice, thereby improving the safety and convenience of using the charging cable in cold weather;

[0021] By using an airbag sleeve filled with air wrapped around the outside of the charging cable, a buffer layer can be formed on the outside of the charging cable, which can not only prevent the surface of the charging cable from being worn and damaged, but also use the airbag sleeve as a buffer layer to prevent the charging cable from being stepped on and damaged, thereby further extending the service life of the charging cable;

[0022] Through the functional components set up, after the user finishes charging, the charging cable can be automatically reeled up by rotating the reel shaft, which is not only convenient for manually putting back the charging gun and charging cable, but also most of the reeled charging cables are inside the semicircular fixed box and the semicircular movable box, which can prevent the charging cables from being scattered on the ground and being stepped on and damaged, thereby improving the safety of the charging cables when not in use;

[0023] The protective cover and the airbag ring are used to form external protection between the charging gun and the car charging port, so as to prevent rain and snow from falling between the car charging port and the charging gun in rainy and snowy weather, and to prevent rainwater from seeping into the connection between the two and affecting the safety of charging. At the same time, it also prevents ice from forming between the charging gun and the car charging port when the outside temperature is too low, so that users can pull out the charging gun normally after charging is completed.

[0024] After the charging gun is fully charged, the snow on the outer surface of the protective cover is scraped off by a continuously rotating scraper to prevent the snow from accumulating on the protective cover and affecting subsequent use. Not only does it not need to manually remove the snow on the protective cover, but it also prevents the snow on the outside of the protective cover from falling into the inside of the plug-in port when the charging gun is put back into the plug-in port, thereby preventing the inside of the plug-in port from getting wet.

[0025] Under the elastic adaptability of the airbag ring, it can fit tightly with the inner wall of the gun port, and then cooperate with the protective cover to play a good sealing and protective role after the charging gun is put back into the gun port, reducing external moisture and dust from entering the gun port;

[0026] The conical ring can be used to further scrape off the residual rain and snow attached to the outer surface of the airbag sleeve to prevent rain and snow from entering the interior of the semicircular fixed box and the semicircular movable box, while the cotton strips will further absorb the water droplets on the outer surface of the airbag sleeve, thereby ensuring the dryness of the charging cable and the airbag sleeve after they are retracted into the semicircular fixed box and the semicircular movable box, avoiding the charging cable and the airbag sleeve from freezing again inside the semicircular fixed box and the semicircular movable box, and also preventing the two from getting damp and affecting subsequent use.

[0049] The present invention will be further described below in conjunction with the embodiments.

[0050] Embodiments of the present invention are as follows:

[0051] This charging station is mainly suitable for extremely cold areas.

[0052] Embodiment 1:

[0053] like Figures 1 to 5 As shown, an antifreeze charging pile for extremely cold regions includes a charging pile body 1, and a controller is arranged inside the charging pile body 1. A gun insertion port 11 is arranged on the outer wall of one side of the charging pile body 1, and a charging gun 12 is connected to the internal buckle of the gun insertion port 11. The buckle connection between the charging gun 12 and the gun insertion port 11 is a prior art, specifically an electromagnetic lock buckle structure, and an unlocking switch for opening the electromagnetic lock buckle is arranged on one side of the hand-held part of the charging gun 12. A charging cable 13 is electrically connected between the bottom of the charging gun 12 and the bottom of the charging pile body 1, and an antifreeze combination mechanism is arranged on the charging pile body 1 and on the same side as the charging cable 13, and the antifreeze combination mechanism includes an antifreeze component;

[0054] The antifreeze component includes a mounting box 21 fixedly connected to the outer wall of one side of the charging pile body 1, and an air pump 22 is fixedly installed inside the mounting box 21. The air pump 22 is started and shut down by the controller inside the charging pile body 1. The air inlet end at the top of the air pump 22 is connected to an air inlet pipe, and the air inlet pipe passes through the mounting box 21 and extends to the outside of the mounting box 21. The air outlet end of the air pump 22 away from the charging pile body 1 is connected to an air supply pipe 23, and an electromagnetic valve 24 is installed on the air supply pipe 23. The outer sleeve of the charging cable 13 is provided with an air bag sleeve 25, and the end of the air bag sleeve 25 close to the air pump 22 is connected to the air supply pipe 23. The air bag sleeve 25 is made of polyurethane rubber, which has good elasticity and strong wear resistance, heat resistance and low temperature resistance. And the air bag sleeve 25 is initially in an uninflated empty state.

[0055] One end of the airbag sleeve 25 close to the charging gun 12 is connected to an air outlet pipe 26, and a solenoid valve 27 is installed on the air outlet pipe 26. The solenoid valve 1 24 and the solenoid valve 2 27 are controlled to open and close by the controller inside the charging pile body 1, and both are in a closed state initially. The upper and lower ends of the airbag sleeve 25 are provided with connecting ends 28. Note: The two connecting ends 28 are not airbag structures. The outer walls of the two connecting ends 28 are connected to clamps 29. The upper and lower ends of the airbag sleeve 25 are fastened to the outer walls of the upper and lower ends of the charging cable 13 through the corresponding clamps 29 to ensure the stability of the charging cable 13 after being sleeved on the outside of the airbag sleeve 25 to prevent the airbag sleeve 25 from falling off.

[0056] Furthermore, if Figures 1 to 4 and Figure 5 , Figure 6 As shown, the antifreeze combination mechanism also includes a functional component, which includes a semicircular fixed box 31 fixedly connected to the outer wall of one side of the charging pile body 1, the semicircular fixed box 31 is located directly above the mounting box 21, and a semicircular movable box 32 is detachably connected to the side of the semicircular fixed box 31 away from the charging pile body 1, and the semicircular fixed box 31 and the semicircular movable box 32 are plug-in compatible, and specifically, to ensure the firmness of the plug-in between the two, the two are connected by screw threads; the detachable setting is convenient for maintenance personnel to manually separate the semicircular movable box 32 from the semicircular fixed box 31, so that the maintenance personnel can inspect the charging cable 13, and an annular sealing ring is provided on the surface of one side where the two are in contact with each other, which is used to improve the sealing of the connection between the two and prevent external moisture from entering.

[0057] Both the semicircular fixed box 31 and the semicircular movable box 32 are provided with through holes for the charging cable 13 and the airbag sleeve 25 to pass through. The interior of the semicircular fixed box 31 is rotatably connected to the winding shaft 33. Initially, most of the charging cables 13 are wound on the outer ring surface of the winding shaft 33. A combination disk 34 is fixedly connected inside the semicircular fixed box 31 and on both sides of the winding shaft 33. A driving motor 35 is fixedly installed inside one side of the charging pile body 1 and at a position corresponding to the position of the winding shaft 33. The output shaft of the driving motor 35 close to the combination disk 34 passes through the semicircular fixed box 31 and the combination disk 34 and is fixedly connected to the winding shaft 33. The combination disk 34 is composed of two fixedly connected disks, and a small circular hole is opened on the disk close to the driving motor 35 for the output shaft of the driving motor 35 to pass through, and a large circular hole is opened on the disk away from the driving motor 35 for the winding shaft 33 to pass through. In addition, the above-mentioned charging cable 13 and the airbag sleeve 25 are inserted into the combination disk 34 from the large circular hole and are wound. Specifically, Figures 3 to 5As shown, a wire hole for the power supply cable 13 and the airbag sleeve 25 to pass through is opened on the winding shaft 33. The power cable 13 and the airbag sleeve 25 are passed through the wire hole and wound around the outer wall of the winding shaft 33. It should be noted that since the power supply cable 13 is relatively wide and its total length is not particularly long, the number of winding turns on the winding shaft 33 will not be too many, and when the power supply cable 13 and the airbag sleeve 25 are wound on the winding shaft 33, too much twisting will not occur to cause the airbag sleeve 25 to fail to inflate normally. After the charging gun 12 is normally removed and the wound power supply cable 13 is pulled out, the power supply cable 13 and the airbag sleeve 25 sleeved on the outside thereof should also be in a completely relaxed state, which will not affect the subsequent inflation and expansion of the airbag sleeve 25.

[0058] When the functional components are used: the user removes the charging gun 12 from the gun insertion port 11. At this time, the user can hold the charging gun 12 and gradually pull out the charging cable 13 wound on the outer ring surface of the reel 33, and gradually extend it from the semicircular fixed box 31 and the semicircular movable box 32. During the process, the reel 33 and the output shaft of the drive motor 35 will rotate forward under the friction between the charging cable 13 and the reel 33. After the charging cable 13 is extended to an appropriate length, the insertion end of the charging gun 12 is inserted into the charging port of the new energy vehicle to start charging the new energy vehicle.

[0059] When charging is completed, the user separates the charging gun 12 from the car charging port. At this time, the controller inside the charging pile body 1 starts the drive motor 35, causing its output shaft to start rotating in the opposite direction. Then, the charging cable 13 can be gradually retracted to the outer ring surface of the winding shaft 33, and gradually retracted into the semicircular fixed box 31 and the semicircular movable box 32 for winding and reeling. After the charging cable 13 is retracted, the charging gun 12 can be put back into the gun insertion port 11, thereby completing the automatic storage of the charging cable 13.

[0060] Therefore, through the set functional components, after the user finishes charging, the charging cable 13 can be automatically reeled up by rotating the reel-up shaft 33, which not only facilitates the manual replacement of the charging gun 12 and the charging cable 13 and improves convenience, but also most of the reeled-up charging cable 13 is inside the semicircular fixed box 31 and the semicircular movable box 32, which can prevent the charging cable 13 from falling on the ground and being stepped on and damaged, thereby improving the safety of the charging cable 13 when not in use.

[0061] When the antifreeze component is used: in the process of charging the car through the charging gun 12 and the charging cable 13, as the charging gun 12 is removed from the gun port 11, the charging cable 13 is pulled out from the semicircular fixed box 31 and the semicircular movable box 32, and the airbag sleeve 25 sleeved on the outside of the charging cable 13 is also pulled out. At this time, the controller inside the charging pile body 1 will also start the air pump 22 and open the solenoid valve 124 at the same time. As the air pump 22 is started, it will suck the outside air from the air inlet end into the air inlet pipe, and then send the air into the air supply pipe 23 from the exhaust end. The air is gradually sent into the airbag sleeve 25 through the air supply pipe 23, causing the deflated airbag sleeve 25 to gradually expand, until the airbag sleeve 25 is filled with air, and then the air pump 22 and the solenoid valve 124 are closed to keep the airbag sleeve 25 in an expanded state. When the airbag sleeve 25 is used in a cold external environment, the snow and ice on the outer surface of the charging cable 13 will be transferred to the outer surface of the airbag sleeve 25 .

[0062] When charging is finished, the controller inside the charging pile body 1 will open the electromagnetic valve 27 to gradually release the air inside the airbag sleeve 25, and gradually restore it to a deflated state under the action of the resilience of the airbag sleeve 25. As the airbag sleeve 25 is deflated, the snow and ice attached to the outer surface of the airbag sleeve 25 will lose support, causing the snow and ice to fall off the outer surface of the airbag sleeve 25. At the same time, under the action of the shaking force generated during the gradual retraction of the charging cable 13, the snow and ice are further separated from the airbag sleeve 25.

[0063] Therefore, by setting up the antifreeze component, when the charging cable 13 is used in cold weather, a protective layer is formed on the outside of the charging cable 13 by using the air-filled airbag sleeve 25, which can not only prevent snow and ice from directly adhering to the outer surface of the charging cable 13 and affecting the normal charging of the charging cable 13, but also after charging is completed, the airbag sleeve 25 will release the air inside, causing the ice and snow on its outer surface to fall off, and there is no need to manually remove the snow and ice, thereby improving the safety and convenience of using the charging cable 13 in cold weather.

[0064] In addition, during the charging process of the charging cable 13, the airbag sleeve 25 is always filled with air. During the use of the charging cable 13, it is inevitable that part of the charging cable 13 will be scattered on the ground, and the scattered charging cable 13 is easily stepped on and damaged. By using the airbag sleeve 25 wrapped around the outside of the charging cable 13 and filled with air, a buffer layer can be formed on the outside of the charging cable 13, which can not only prevent the surface of the charging cable 13 from being worn and damaged, but also use the airbag sleeve 25 as a buffer layer to prevent the charging cable 13 from being stepped on and damaged, thereby further improving the service life of the charging cable 13.

[0065] Embodiment 2:

[0066] like Figure 1 , Figures 7 to 10 As shown, the above-mentioned antifreeze charging pile for extremely cold regions also includes a charging protection mechanism arranged on the charging gun 12, and the charging protection mechanism includes a protection component, and the protection component includes a protection cover 41 fixedly connected to the outer wall of the charging gun 12, and the protection cover 41 is located on the charging gun 12 near the side of its insertion port, and the protection cover 41 is bowl-shaped and made of transparent acrylic material, so that the user can see the position of the car charging port through the protection cover 41 when inserting the charging gun 12. An airbag ring 42 is arranged on one side of the protection cover 41 near the bowl mouth, and the airbag ring 42 is filled with air, and a plurality of heat dissipation holes 43 are evenly arranged on the lower outer wall of the protection cover 41.

[0067] Furthermore, the above-mentioned charging protection mechanism also includes a linkage component, which includes a branch pipe 44 connected to the end of the air outlet pipe 26 away from the airbag sleeve 25, and the upper end of the branch pipe 44 is connected to a cavity tube 45, and a plurality of square holes are evenly opened on the side of the cavity tube 45 away from the branch pipe 44. The function of the square holes is to facilitate the normal discharge of air entering the cavity tube 45.

[0068] The cavity barrel 45 is fixedly connected to the outer wall of the charging gun 12 away from the protective cover 41. The cavity barrel 45 is rotatably connected with a shaft fan 46. The branch pipe 44 connected to the cavity barrel 45 is provided with an air outlet nozzle 441. The air outlet nozzle 441 is funnel-shaped, and the position of the air outlet nozzle 441 corresponds to the position of the shaft fan 46. The funnel-shaped air outlet nozzle 441 ensures that the air blown out of the branch pipe 44 can better act on the surface of the shaft fan 46 to drive the shaft fan 46 to rotate stably. The air outlet nozzle 441 is located inside the cavity barrel 45.

[0069] A gear 47 is coaxially fixedly connected to the side of the axial fan 46 away from the branch pipe 44, and a fixed ring 48 is fixedly connected to the protective cover 41 at a position corresponding to the gear 47. A gear ring 49 is rotatably connected to the outer ring surface of the fixed ring 48, and the gear ring 49 and the gear 47 are meshed with each other. A scraper 410 is fixedly connected to the side of the gear ring 49 close to the protective cover 41, and a triangular block is provided at the bottom of the scraper 410, and the bottom of the triangular block is in contact with the outer surface of the protective cover 41, so that the triangular block can better scrape off the snow attached to the outer surface of the protective cover 41.

[0070] A shielding box 411 is fixedly connected to the outer wall of the charging gun 12 and the position corresponding to the position of the gear 47 and the gear ring 49. The shielding box 411 is sleeved on the outside of the gear 47 and the gear ring 49 to prevent rain and snow from falling on the two and affecting the normal transmission of the two. The side of the shielding box 411 facing the protective cover 41 is open. The function of the open part is to ensure that the scraper 410 will not be blocked by the shielding box 411 when performing a circular motion.

[0071] When in use: When the user connects the charging gun 12 to the charging port of the car for charging, as the insertion end of the charging gun 12 is connected to the charging port of the car, the airbag ring 42 will fit around the charging port of the car, and the protective cover 41 will cover the charging port of the car. In this way, the protective cover 41 and the airbag ring 42 form an external protection between the charging gun 12 and the charging port of the car, so as to prevent rain and snow from falling between the charging port of the car and the charging gun 12 in rainy and snowy weather, and to prevent rainwater from penetrating into the connection between the two and affecting the safety of charging. At the same time, it also prevents the charging gun 12 and the charging port of the car from freezing when the outside temperature is too low, so that the user can normally pull out the charging gun 12 after charging is completed. The multiple heat dissipation holes 43 arranged under the protective cover 41 can not only prevent rain and snow from entering, but also provide heat dissipation between the charging gun 12 and the charging port of the car, and prevent heat from accumulating inside the protective cover 41 during charging, so as to ensure the safety of charging.

[0072] In addition, when charging is completed, as the solenoid valve 27 opens, the air inside the airbag sleeve 25 is released, and the exhausted air at this time will enter the interior of the branch pipe 44, and cause the air to blow from the air outlet nozzle 441 to the axial fan 46, thereby driving the axial fan 46 to rotate continuously, and then the axial fan 46 drives the gear 47 to rotate synchronously. As the gear 47 rotates, the gear ring 49 will be driven to rotate in the opposite direction, and then the scraper 410 will be driven by the gear ring 49 to make a circular motion along the outer surface of the protective cover 41.

[0073] Therefore, after the charging gun 12 is fully charged, the scraper 410 that can rotate continuously is used to scrape off the snow attached to the outer surface of the protective cover 41, so as to prevent the snow from accumulating on the protective cover 41 and affecting the subsequent use. Not only does it not need to manually remove the snow on the protective cover 41, but it also prevents the snow outside the protective cover 41 from falling into the inside of the gun insertion port 11 after the charging gun 12 is put back into the gun insertion port 11, so as to prevent the inside of the gun insertion port 11 from getting wet. When the charging gun 12 is put back into the gun insertion port 11, the protective cover 41 and the airbag ring 42 will also enter the inside of the gun insertion port 11 together. During the process, the airbag ring 42 is squeezed by the inner wall of the gun insertion port 11 and deformed, so that under the elastic adaptability of the airbag ring 42, it can fit tightly with the inner wall of the gun insertion port 11, and then cooperate with the protective cover 41 to play a good sealing and protective role after the charging gun 12 is put back into the gun insertion port 11, reducing the external moisture and dust from entering the inside of the gun insertion port 11.
