Description

Technical Field

[0001] The invention belongs to the technical field of charging piles, and specifically relates to an outdoor charging pile for new energy vehicles. Background Art

[0002] New energy vehicle outdoor charging piles are facilities that provide charging services for electric vehicles. They are usually installed outdoors and are suitable for various places, such as residential areas, commercial areas, and highway service areas. Outdoor charging piles are usually divided into fast charging piles and slow charging piles. Existing charging piles are all intelligent, and the charging information can be obtained in real time through the display screen on the surface.

[0003] When outdoor charging piles charge new energy vehicles, the high-power charging will cause the electronic components (such as power semiconductors) in the internal charging module to generate a lot of heat, which will cause the internal temperature of the outdoor charging pile to rise. High temperature will cause the working efficiency of the battery and charging system to decrease. At the same time, in a high temperature environment, electronic components (such as power modules, control chips, etc.) will also accelerate aging and reduce their service life.

[0016] The beneficial effects of the present invention are as follows: 1. The outdoor charging pile for new energy vehicles described in the present invention is a kind of outdoor charging pile for new energy vehicles. The gas from the outside is sucked into the air intake frame through the breathable cloth. The breathable cloth can reduce the impurities from the outside from being sucked into the air intake frame, thereby ensuring that only the gas is sucked in, and at the same time effectively protecting the normal operation of the fan blades. The refrigeration sheet makes the temperature of the gas lower when it enters the charging pile body, which is more conducive to cooling the charging pile body. At the same time, the heat-generating side of the refrigeration sheet is in close contact with the heat pipe, so the heat will be discharged by the heat pipe, and will not enter the charging pile body again. When the gas is sucked in by the fan blades, it will quickly fill into several hollow roll films, so that the originally rolled roll film will quickly expand and expand, and then become a straight strip roll film, which is convenient for the inhaled cold air to be discharged through the air vents. The hot air in the charging pile body will be discharged through the air outlet frame, thereby cooling the inside of the charging pile body. Through the designed cooling mechanism and guide assembly, when the inside of the charging pile body starts to heat up, the outside air is immediately sucked in and cooled down, thereby suppressing the heating of the charging pile body. At the same time, with the designed guide component, the end of the charging pile body away from the air intake frame can also be cooled quickly, thereby achieving efficient cooling of the charging pile body. It effectively protects the electronic components in the charging pile body, prevents the electronic components from aging due to high temperature, prolongs their service life, and also improves the working efficiency of the charging pile body.

[0017] 2. In the outdoor charging pile for new energy vehicles described in the present invention, since the fan blades are started to cool down as soon as the temperature in the charging pile body just starts to rise, the fan blades do not need to keep rotating at a high speed, but only need to keep rotating at a low speed to continuously absorb the external gas. The fan blades rotating at a low speed can reduce power consumption and be more energy-saving and environmentally friendly; at the same time, since charging takes a period of time, rotating at a low speed and inhaling gas for a long time to cool down is also more in line with actual use requirements. The connecting plate slides and squeezes in the fixed pipe with the exhaust pipe, and the gas in the fixed pipe and the connecting frame is squeezed and sprayed out by squeezing the exhaust pipe, so that the hot air at the bottom of the charging pile body is blown to the air outlet frame, thereby accelerating the discharge of the hot air in the charging pile body. The gas in the first elastic member is squeezed into the air outlet pipe and blown out, and the cold air at the high part of the charging pile body is blown to the low part by using the inclined air outlet pipe, thereby accelerating the cooling of the low part of the charging pile body.

[0018] 3. The outdoor charging pile for new energy vehicles described in the present invention allows the gas in the second elastic member to enter the hollow membrane through the conduit, so that the hollow membrane expands rapidly, and then covers the charging cover of the new energy vehicle. When charging on rainy days, the expanded hollow membrane is used to protect the charging port of the new energy vehicle and the port of the charging gun, effectively reducing the flow of rainwater to the port of the charging gun, which causes the charging gun to be damaged after water ingress. Since the second elastic member continuously inflates the hollow membrane, after the hollow membrane expands to the maximum limit, the shrinkage hole at the top will be stretched open, and then the excess gas filled in will be discharged, avoiding the hollow membrane from being over-filled with gas and ruptured. When the charging gun is not in use and inserted into the socket, and the second elastic member is no longer inflating the hollow membrane, the gas in the hollow membrane will slowly leak out through the vent hole, so that the hollow membrane is in a deflated state again, which is convenient for using the charging gun and inspecting and repairing the socket. At the same time, the second elastic member can assist in accelerating the resetting of the connecting plate, so that the gas in the charging pile body can be quickly sucked into the connecting frame.

[0019] 4. The outdoor charging pile for new energy vehicles described in the present invention rotates the arc-shaped sealing plate into the connecting pipe through the arc-shaped top plate, so that the first magnetic block on one side of the sealing plate and the second magnetic block in the connecting pipe are mutually adsorbed and fixed, thereby isolating the connecting pipe. After the connecting pipe is isolated, the hot air introduced into the connecting pipe by the heat conducting pipe will flow to the outside through the port, preventing the hot air from flowing to the socket, resulting in high temperature at the socket. And the boss will move with the guard plate when moving up and down, thereby closing the charging pile body and preventing impurities from entering the charging pile body through the rectangular groove. When the charging pile body is not in use, the sealing plate is rotated and reset by the torsion spring, so that the connecting pipe remains unobstructed. The hot air emitted by the refrigeration plate will enter the fixed ring through the heat conducting pipe and the connecting pipe, and blow to the hollow membrane that is still in an expanded state through the blowing hole of the fixed ring, quickly drying the hollow membrane, thereby effectively reducing rainwater from entering the charging pile body.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 11 As shown, an outdoor charging pile for new energy vehicles according to an embodiment of the present invention comprises a charging pile body 1, a display screen 2 is provided on one side of the charging pile body 1, and a socket 3 for connecting a charging gun 4 is provided on one side of the charging pile body 1; a cooling mechanism 10 is provided in the charging pile body 1. The cooling mechanism 10 comprises an air intake frame 11 and an air outlet frame 12 provided on both sides of the charging pile body 1, and a breathable cloth 13 is fixedly installed in both the air intake frame 11 and the air outlet frame 12, a servo motor 14 is fixedly installed in the air intake frame 11, and a fan blade 15 is fixedly installed at the output end of the servo motor 14, a cooling sheet 16 is fixedly installed in the air intake frame 11, and a heat pipe 17 in the air intake frame 11 is fixedly installed in the charging pile body 1, one end of the heat pipe 17 is in contact with the cooling sheet 16, and the end of the heat pipe 17 away from the cooling sheet 16 is outside the charging pile body 1.

[0035] Specifically, a guide assembly 18 in the charging pile body 1 is provided at one end of the air intake frame 11. The guide assembly 18 includes two guide plates 181 fixedly installed in the charging pile body 1, and a plurality of hollow roll films 182 are fixedly installed at one end of the two guide plates 181 close to each other. One end of the roll film 182 is connected to the air intake frame 11, and a plurality of through holes 183 connected to the inside are provided on the side wall of the roll film 182. A connecting cloth 184 is fixedly installed in the through hole 183, and a plurality of air holes 185 connected to the inside of the roll film 182 are provided on the surface of the connecting cloth 184. A temperature sensor and a controller for controlling the start and stop of the servo motor 14 are provided in the charging pile body 1.

[0036] During operation, when the charging pile body 1 charges the new energy vehicle through the charging gun 4, since charging takes a certain amount of time, and the charging module and electronic components in the charging pile body 1 will generate heat due to high-power charging, when the temperature sensor detects that the internal temperature of the charging pile body 1 rises (reaches a preset value, which can be set according to actual conditions to be more in line with the use environment), the servo motor 14 is started through the controller.

[0037] By starting the servo motor 14, the fan blade 15 starts to rotate, and the external gas is sucked into the air intake frame 11 through the breathable cloth 13 (the breathable cloth 13 is made of waterproof and breathable material). The breathable cloth 13 can reduce the external impurities sucked into the air intake frame 11, thereby ensuring that only gas is sucked in, and at the same time effectively protecting the normal operation of the fan blade 15. When the fan blade 15 rotates, the cooling plate 16 is also started. Due to the characteristics of the cooling plate 16 that one side is hot and the other side is cold, the cold side of the cooling plate 16 is exposed in the air intake frame 11, thereby assisting in cooling the gas sucked from the outside, so that the temperature of the gas is lower when it enters the charging pile body 1, which is more conducive to cooling the charging pile body 1. At the same time, since the heating side of the cooling plate 16 is in close contact with the heat pipe 17, the heat will be discharged by the heat pipe 17, and will not enter the charging pile body 1 again.

[0038] When the gas is sucked into the fan blades 15, it will quickly fill into several hollow rolls 182, causing the originally rolled roll 182 to quickly expand and expand, and then become a straight strip of roll 182. The connection cloth 184 with air holes 185 is installed at the through hole 183 of the roll 182, so that when the roll 182 is in the rolled state and starts to be inflated, the connection cloth 184 is in a rolled up and stacked state, thereby reducing air leakage and facilitating the rapid inflation of the roll 182. When the roll 182 is stretched out, the connection cloth 184 is in a stretched straight state, and the air holes 185 are in an open state at this time, which is convenient for the inhaled cold air to be discharged through the air holes 185. The hot air in the charging pile body 1 will be discharged through the air outlet frame 12, thereby cooling the inside of the charging pile body 1.

[0039] Through the cooling mechanism 10 and the guide assembly 18 designed as above, when the temperature inside the charging pile body 1 starts to rise, the outside air is immediately sucked in and cooled down, thereby suppressing the temperature rise of the charging pile body 1. At the same time, with the designed guide assembly 18, the end of the charging pile body 1 away from the air intake frame 11 can also be cooled down quickly, thereby achieving efficient cooling of the charging pile body 1. The electronic components in the charging pile body 1 are effectively protected, and the electronic components are prevented from being aged due to high temperature, and their service life is extended, while also improving the working efficiency of the charging pile body 1.

[0040] An auxiliary mechanism 20 for accelerating internal cooling is provided in the charging pile body 1. The auxiliary mechanism 20 includes a hollow connection frame 21 fixedly installed in the charging pile body 1. A plurality of fixed pipes 22 connected to the inside are fixedly installed on the top of the connection frame 21. An exhaust pipe 23 is sealed and slidably connected to the inside of the fixed pipe 22. The port of the connection frame 21 is relatively small. A connection plate 25 is fixedly installed on the top of the plurality of exhaust pipes 23. A through groove 24 connected to the air intake frame 11 is provided in the charging pile body 1. A connecting rod 28 is slidably connected in the through groove 24. The bottom of the connecting rod 28 is fixedly connected to the connecting plate 25. The top of the connecting rod 28 is in the air intake frame 11. A hollow first elastic member 26 is fixedly installed in the through groove 24. A shrinkage hole is provided on the surface of the first elastic member 26. The top of the first elastic member 26 is fixedly connected to the connecting plate 25. A plurality of exhaust pipes 27 connected to the inside of the first elastic member 26 are fixedly installed in the charging pile body 1. An auxiliary component 29 is provided in the air intake frame 11 to drive the air extraction pipe 23 to perform piston movement in the fixed pipe 22 .

[0041] Specifically, the auxiliary component 29 includes a first electromagnet 291 installed on the top of the connecting rod 28 , a sleeve rod 292 is fixedly sleeved on the output end of the servo motor 14 , and a second electromagnet 293 is fixedly installed on one end of the sleeve rod 292 .

[0042] During operation, since the fan blades 15 are started to cool down as soon as the temperature in the charging pile body 1 starts to rise, the fan blades 15 do not need to keep rotating at a high speed, but only need to keep rotating at a low speed to continuously absorb the external gas. The fan blades 15 rotating at a low speed can reduce power consumption and be more energy-saving and environmentally friendly; at the same time, since charging takes a while, rotating at a low speed and inhaling gas for a long time to cool down is more in line with actual use needs.

[0043] When the servo motor 14 rotates, the first electromagnet 291 and the second electromagnet 293 are energized, and the sleeve rod 292 is driven to rotate with the second electromagnet 293. When the second electromagnet 293 rotates close to the first electromagnet 291, the first electromagnet 291 and the second electromagnet 293 repel each other with the same polarity, and then slide and shrink the connecting rod 28 in the direction away from the servo motor 14. When the connecting rod 28 slides and shrinks, it will slide and squeeze the exhaust pipe 23 in the fixed pipe 22 through the connecting plate 25, and squeeze the gas in the fixed pipe 22 and the connecting frame 21 through the exhaust pipe 23, so that the hot air at the bottom of the charging pile body 1 is blown to the air outlet frame 12, thereby accelerating the discharge of the hot air in the charging pile body 1. It should be noted that the connecting plate 25 will squeeze the first elastic member 26 when sliding and contracting, so that the gas in the first elastic member 26 is squeezed into the air outlet pipe 27 and blown out, and the cold air at the high position in the charging pile body 1 is blown to the low position by the inclined air outlet pipe 27, thereby accelerating the cooling of the low position in the charging pile body 1. As the servo motor 14 moves away from the first electromagnet 291 with the sleeve rod 292 and the second electromagnet 293, the connecting plate 25, the connecting rod 28 and the first electromagnet 291 are reset under the action of the first elastic member 26 (the exhaust pipe 23 will suck the gas in the charging pile body 1 into the connecting frame 21 when following the reset of the connecting plate 25), thereby facilitating the next sliding contraction. By reciprocating the above operation, the hot air in the charging pile body 1 can be quickly discharged, and the cold air at the high position of the charging pile body 1 can be quickly guided to the low position, thereby achieving rapid cooling of the charging pile body 1.

[0044] A protection mechanism 30 is provided in the charging pile body 1. The protection mechanism 30 includes a second elastic member 31 fixedly installed in the through groove 24. One end of the second elastic member 31 is fixedly connected to the connecting plate 25. A hollow membrane 32 is fixedly installed on the surface of the charging gun 4. The hollow membrane 32 is connected to the second elastic member 31 through a conduit 33 with a one-way valve. One side of the second elastic member 31 is provided with an air inlet pipe connected to the inside and with a one-way valve. A shrinkage hole is provided on the top of the hollow membrane 32, and an air leakage hole 34 is provided on the surface of the hollow membrane 32.

[0045] During operation, when the charging gun 4 is connected to the charging port of the new energy vehicle, the hollow membrane 32 is in a deflated state, and as the connecting plate 25 continuously slides, squeezes and resets, the second elastic member 31 in the through groove 24 will also be squeezed, and the second elastic member 31 will suck the gas in the charging pile body 1 through the air inlet pipe, and when squeezed, the gas in the second elastic member 31 will enter the hollow membrane 32 through the conduit 33, so that the hollow membrane 32 will expand rapidly, and then cover the charging cover of the new energy vehicle. When charging on rainy days, the expanded hollow membrane 32 is used to protect the charging port of the new energy vehicle and the port of the charging gun 4, effectively reducing the flow of rainwater to the port of the charging gun 4, causing the charging gun 4 to be damaged after water ingress.

[0046] Since the second elastic member 31 continuously inflates the hollow membrane 32, when the hollow membrane 32 expands to the maximum, the shrinkage hole on the top will be stretched open, and then the excess gas filled in will be discharged, so as to avoid the hollow membrane 32 from rupture after being over-filled with gas. It should be noted that the air leakage hole 34 on the hollow membrane 32 is small, and the air leakage speed is much lower than the air filling speed, so in the inflated state, the air leakage of the air leakage hole 34 can be ignored. When the charging gun 4 is not used and inserted into the socket 3, and the second elastic member 31 no longer inflates the hollow membrane 32, the air leakage hole 34 will slowly leak the gas in the hollow membrane 32, so that the hollow membrane 32 is in a deflated state again, which is convenient for using the charging gun 4 and inspecting and repairing the socket 3. At the same time, the second elastic member 31 can assist in accelerating the resetting of the connecting plate, so that the gas in the charging pile body can be quickly sucked into the connecting frame 21.

[0047] A drying mechanism 40 for drying the hollow membrane 32 is provided in the charging pile body 1. The drying mechanism 40 includes a connecting pipe 41 connected to the inside of the heat conducting pipe 17. One end of the connecting pipe 41 is connected to the socket 3 and is close to the hollow membrane 32. A port is provided on one side of the connecting pipe 41. An arc-shaped sealing plate 42 is rotatably connected to the port of the connecting pipe 41 through a torsion spring. A rectangular groove is provided on one side of the charging pile body 1 close to the connecting pipe 41. A boss 43 is fixedly installed on one side of the connecting plate 25. The boss 43 is in the rectangular groove. An arc-shaped top plate 44 made of rubber is fixedly installed on one end of the boss 43 away from the connecting plate 25. A guard plate 45 is fixedly installed on the top and bottom of the boss 43. The guard plate 45 slides in the charging pile body 1.

[0048] Specifically, a first magnetic block 46 is fixedly mounted on one side of the sealing plate 42, and a second magnetic block 47 is fixedly mounted in the connecting pipe 41. A fixing ring 48 connected to the connecting pipe 41 is fixedly mounted in the socket 3, and a blowing hole 49 connected to the inside is opened on one side of the fixing ring 4 close to the charging gun 4.

[0049] During operation, when the connecting plate 25 slides in the through groove 24, it will move up and down with the top plate 44 through the boss 43, and the arc-shaped top plate 44 will rotate the arc-shaped sealing plate 42 into the connecting pipe 41, so that the first magnetic block 46 on one side of the sealing plate 42 and the second magnetic block 47 in the connecting pipe 41 are mutually adsorbed and fixed, thereby isolating the connecting pipe 41. After the connecting pipe 41 is isolated, the hot air introduced into the connecting pipe 41 by the heat conducting pipe 17 will flow to the outside through the port, preventing the hot air from flowing to the socket 3, resulting in high temperature at the socket 3. And the boss 43 will move with the guard plate 45 when moving up and down, thereby closing the charging pile body 1, and preventing impurities from entering the charging pile body 1 through the rectangular groove. When the charging pile body 1 is not in use, the charging pile body 1 stops cooling, and the servo motor 14 no longer drives the fan blade 15 to rotate. At this time, the top plate 44 no longer rotates the sealing plate 42 into the connecting pipe 41, and the sealing plate 42 is reset by rotating the torsion spring, so that the connecting pipe 41 remains unobstructed. Then insert the charging gun 4 into the socket 3. At this time, the expanded hollow membrane 32 begins to deflate through the vent hole 34. Since the vent hole 34 deflates slowly, the hollow membrane 32 remains expanded when the charging gun 4 is inserted into the socket 3, and the cooling plate 16 will continue to work for a period of time after the servo motor 14 stops. At this time, the hot air emitted by the cooling plate 16 will enter the fixed ring 48 through the heat pipe 17 and the connecting pipe 41, and blow to the hollow membrane 32 that is still in the expanded state through the blowing hole 49 of the fixed ring 48, so as to quickly dry the hollow membrane 32, thereby effectively reducing the rainwater from entering the charging pile body 1.

[0050] Working principle: By starting the servo motor 14, it drives the fan blades 15 to start rotating, and the external gas is sucked into the air intake frame 11 through the breathable cloth 13. The breathable cloth 13 can reduce the external impurities sucked into the air intake frame 11, thereby ensuring that only gas is sucked in, and at the same time effectively protecting the normal operation of the fan blades 15. When the fan blades 15 rotate, the cooling plate 16 is also started. Due to the characteristics of the cooling plate 16 that one side is hot and the other side is cold, the cold side of the cooling plate 16 is exposed to the air intake frame 11, thereby assisting in cooling the gas sucked in from the outside, so that the temperature of the gas is lower when it enters the charging pile body 1, which is more conducive to cooling the charging pile body 1. At the same time, since the heated side of the cooling plate 16 is in close contact with the heat pipe 17, the heat will be discharged by the heat pipe 17, and will not enter the charging pile body 1 again. When the gas is sucked into the fan blades 15, it will quickly fill into several hollow roll films 182, causing the originally rolled roll film 182 to quickly expand and expand, and then become a straight strip roll film 182. The connection cloth 184 with air holes 185 is installed at the through hole 183 of the roll film 182 so that when the roll film 182 is in the rolled state and starts to be inflated, the connection cloth 184 is in a rolled up and stacked state, thereby reducing air leakage and facilitating the rapid inflation of the roll film 182. When the roll film 182 is stretched out, the connection cloth 184 is in a stretched straight state, and the air holes 185 are in an open state at this time, which facilitates the inhaled cold air to be discharged through the air holes 185.

[0051] When the servo motor 14 rotates, the first electromagnet 291 and the second electromagnet 293 are energized, and the sleeve rod 292 is driven to rotate with the second electromagnet 293. When the second electromagnet 293 rotates close to the first electromagnet 291, the first electromagnet 291 and the second electromagnet 293 repel each other with the same polarity, and then slide and shrink the connecting rod 28 in the direction away from the servo motor 14. When the connecting rod 28 slides and shrinks, it will slide and squeeze the exhaust pipe 23 in the fixed pipe 22 through the connecting plate 25, and squeeze the gas in the fixed pipe 22 and the connecting frame 21 through the exhaust pipe 23, so that the hot air at the bottom of the charging pile body 1 is blown to the air outlet frame 12, thereby accelerating the discharge of the hot air in the charging pile body 1. It should be noted that the connecting plate 25 will squeeze the first elastic member 26 when sliding and contracting, so that the gas in the first elastic member 26 is squeezed and enters the air outlet pipe 27 and blows out, and the cold air at the high place in the charging pile body 1 is blown to the low place by the inclined air outlet pipe 27, thereby accelerating the cooling of the low place in the charging pile body 1. As the servo motor 14 drives the sleeve rod 292 and the second electromagnet 293 away from the first electromagnet 291, the connecting plate 25, the connecting rod 28 and the first electromagnet 291 are reset under the action of the first elastic member 26, which facilitates the next sliding and contraction.

[0052] When the charging gun 4 is connected to the charging port of the new energy vehicle, the hollow membrane 32 is in a deflated state, and as the connecting plate 25 is continuously slid, squeezed and reset, the second elastic member 31 in the through groove 24 will also be squeezed, and the second elastic member 31 will suck the gas in the charging pile body 1 through the air inlet pipe, and when being squeezed, the gas in the second elastic member 31 will enter the hollow membrane 32 through the conduit 33, so that the hollow membrane 32 will expand rapidly, and then cover the charging cover of the new energy vehicle. Since the second elastic member 31 continuously inflates the hollow membrane 32, when the hollow membrane 32 expands to the maximum limit, the shrinkage hole at the top will be stretched open, and then the excess gas filled in will be discharged, so as to avoid the hollow membrane 32 from being over-filled with gas and then ruptured. It should be noted that the air leakage hole 34 on the hollow membrane 32 is small, and the air leakage speed is much lower than the air filling speed, so in the inflated state, the air leakage of the air leakage hole 34 can be ignored. When the charging gun 4 is not in use and is inserted into the socket 3, and the second elastic member 31 is no longer inflating the hollow membrane 32, the air leakage hole 34 will slowly leak the gas in the hollow membrane 32, so that the hollow membrane 32 is in a deflated state again, which is convenient for using the charging gun 4 and inspecting and repairing the socket 3. At the same time, the second elastic member 31 can help accelerate the resetting of the connecting plate, so that the gas in the charging pile body can be quickly sucked into the connecting frame 21.

[0053] When the connecting plate 25 slides in the through groove 24, it will move up and down with the top plate 44 through the boss 43. The arc-shaped top plate 44 rotates the arc-shaped sealing plate 42 into the connecting pipe 41, so that the first magnetic block 46 on one side of the sealing plate 42 and the second magnetic block 47 in the connecting pipe 41 are mutually adsorbed and fixed, thereby isolating the connecting pipe 41. When the charging pile body 1 is not in use, the charging pile body 1 stops cooling, and the servo motor 14 no longer drives the fan blades 15 to rotate. At this time, the top plate 44 no longer rotates the sealing plate 42 into the connecting pipe 41. The sealing plate 42 is reset by rotating the torsion spring, so that the connecting pipe 41 remains unobstructed. Then insert the charging gun 4 into the socket 3. At this time, the expanded hollow membrane 32 begins to vent through the vent hole 34. Since the vent hole 34 vents slowly, when the charging gun 4 is inserted into the socket 3, the hollow membrane 32 remains in an expanded state, and the cooling plate 16 will continue to work for a period of time after the servo motor 14 stops. At this time, the hot air emitted by the cooling plate 16 will enter the fixed ring 48 through the heat pipe 17 and the connecting pipe 41, and blow to the hollow membrane 32 which is still in the expanded state through the blowing holes 49 of the fixed ring 48, so as to quickly dry the hollow membrane 32.
