[0001] This invention relates to the field of charging pile technology, and in particular to a charging pile with rapid heat dissipation function for new energy vehicles. Background Technology

[0002] A car charging station is a device for charging new energy vehicles. When in use, the user removes the charging cable from the charging station and then connects it to the electric vehicle that needs charging. However, most existing car charging stations are installed in public places such as streets and parking lots, and most of them are installed on the ground. This not only occupies a lot of public space, but also, due to the high volume of pedestrian and vehicle traffic on the streets, the charging stations installed on the street can have a certain impact on passing pedestrians and vehicles. At the same time, passing vehicles are very likely to scratch the charging station, causing damage to the equipment and leading to leakage from the charging station, which could cause injury to passing pedestrians.

[0014] This invention provides a charging pile with rapid heat dissipation function for new energy vehicles, which has the following advantages compared with the prior art:

[0015] 1. This invention controls the device to move downwards underground via a control terminal, saving ground space without affecting the charging effect, while also avoiding pedestrian injuries caused by vehicle collisions, thus improving safety.

[0016] 2.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Example 1: A charging pile with rapid heat dissipation function for new energy vehicles, as shown in Figures 1-3, includes a cylindrical body 1, a cylindrical cover 2 on the upper part of the cylindrical body 1, a charging column 3 slidably connected to the middle of the cylindrical cover 2, a deep hole in the lower part of the charging column 3, a support ring 4 fixedly connected to the lower part of the deep hole of the charging column 3, and three through holes evenly distributed in the circumferential direction in the support ring 4. A cylindrical first cavity 5 is formed in the lower part of the cylindrical body 1, a first motor 6 and a control terminal are installed in the middle of the first cavity 5, the control terminal is electrically connected to the first motor 6, a large lead screw 7 is fixedly connected to the output shaft of the first motor 6, the output shaft of the first motor 6 is rotatably connected to the cylindrical body 1, and a guide cylinder 8 is fixedly connected inside the cylindrical body 1. The upper parts of the large lead screw 7 and the guide cylinder 8 are both located in the deep hole in the lower part of the charging column 3. The lower part of the guide cylinder 8 is frustum-shaped, and the upper part of the guide cylinder 8 is circumferentially shaped. Three cylindrical rods are distributed to restrict the rotation of the support ring 4 and the transmission ring 9. The lower side of the charging column 3 is shaped to match the lower frustum of the air guide frustum 8. The middle part of the air guide frustum 8 is rotatably connected to the large lead screw 7. The cylindrical rod of the air guide frustum 8 is slidably connected to the support ring 4. The cylindrical rod of the air guide frustum 8 is slidably connected to the transmission ring 9. The large lead screw 7 is threadedly connected to the transmission ring 9. A second cavity 10 is opened in the upper part of the charging column 3. The charging device is placed in the second cavity 10. The rotation of the first motor 6 drives the large lead screw 7 to rotate, and the transmission ring 9 and the support ring 4 move upward. This controls the charging column 3 to retract into the cylinder 1 after charging is completed, saving ground space and improving the utilization rate of urban space. The charging column 3 is equipped with a water-proof heat dissipation mechanism for heat dissipation of the charging components and an anti-blocking mechanism for preventing the heat dissipation air inlet from being blocked.

[0034] As shown in Figures 4-6, the water-proof heat dissipation mechanism includes a square shell 11, which is fixedly connected to the charging post 3. The charging post 3 is fixedly connected to a diverter plate 12, and the surface of the diverter plate 12 has through holes distributed at equal intervals. The square shell 11 is located on one side of the second cavity 10. The upper part of the charging post 3 has a through hole, and the second cavity 10 communicates with the deep hole of the charging post 3 through the through hole to transport the air in the second cavity 10 to the deep hole of the charging post 3. The diverter plate 12 is located at the upper part of the second cavity 10. The square shell 11 is provided with a suction column 13, and the upper side of the suction column 13 has an air inlet hole communicating with the outside. The cylinder cover 2 has symmetrical openings. Two unidirectional exhaust ports 14 are distributed to expel hot air and moisture from the device. An air guide hole 15 is provided inside the suction column 13, communicating with the air inlet on the right side of the suction column 13. The air inlets of the suction column 13 are arranged in equally spaced strips, with their orientation slightly downwards. An air pump 16 is installed at the lower part of the suction column 13 to deliver external gas to the second cavity 10 for cooling the charging components. The control terminal is electrically connected to the air pump 16, and the air inlet of the air pump 16 communicates with the air guide hole 15. The square shell 11, the flow divider 12, and the charging column 3 cooperate to form the first chamber. The exhaust port of the air pump 16 communicates with the second chamber. A chamber is connected, and a float plate 17 is slidably connected inside the air inlet on the right side of the suction column 13. This float plate 17 is used to detect the external water level and control the opening and closing of the air inlet of the suction column 13 to prevent external water from flowing into the device. The upper side of the float plate 17 has circumferentially evenly spaced grooves to ensure that external air can always flow into the suction column 13 when the first airbag 20 is not inflated. The lower side of the float plate 17 is slidably connected to a first piston 18, and a spring connects the float plate 17 and the first piston 18. A sealing truncated cone 19 is fixedly connected to the upper side of the float plate 17, and the first airbag 20 is fixedly connected to the upper side of the float plate 17. The first airbag 20 is located on the sealing truncated cone. At the maximum diameter of 19, the float plate 17 and the first piston 18 cooperate to form a second chamber, which contains hydraulic oil. The upper side of the float plate 17 has a through hole, and the second chamber is connected to the first airbag 20 through the through hole to control the expansion and contraction of the first airbag 20. The first airbag 20 is squeezed and cooperated with the suction column 13 to seal the suction column 13. Hydraulic oil is stored in both the first airbag 20 and the through hole of the float plate 17. The float plate 17 uses buoyancy to drive the first piston 18 to move, thereby controlling the expansion of the first airbag 20 to block the suction column 13 and prevent external water from flowing into the device and causing damage to the charging equipment.

[0035] As shown in Figures 5 and 7, the anti-blocking mechanism includes an air duct 21. The upper end of the air duct 21 is connected to the exhaust port of the air pump 16, and the lower end of the air duct 21 is connected to a second airbag 22. The second airbag 22 is fixedly connected to the suction column 13. A through hole communicating with the first chamber is opened in the middle of the air duct 21, and a first pressure valve 23 is installed at the through hole. The trigger pressure value of the first pressure valve 23 is the pressure inside the air duct 21 when the second airbag 22 is inflated to its maximum. The second airbag 22 is connected to the air duct 15 through the duct. A second pressure valve 24 is installed between the suction column 13 and the air inlet of the second airbag 22. A one-way valve is installed at the air inlet of the second airbag 22 to prevent the gas inside the second airbag 22 from flowing back. The trigger pressure value of the second pressure valve 24 is the pressure difference between the pressure inside the second airbag 22 when it is expanded to its maximum and the negative pressure generated when the air guide hole 15 is blocked. The gas ejection from the second airbag 22 is controlled by the pressure change inside the air guide hole 15. The force of the gas is used to flush out leaves and other objects adsorbed on the air inlet of the suction column 13, preventing them from affecting the heat dissipation effect of the device.

[0036] When someone needs to use this device, the control terminal starts the first motor 6, which drives the large lead screw 7 to rotate. The transmission ring 9 moves upward, pushing the support ring 4 and the charging column 3 upward together. When the transmission ring 9 pushes the support ring 4 to the top of the air guide truncated cone 8, the first motor 6 stops. The user then removes the charging cable from the second cavity 10 for charging. At this time, the control terminal starts the air pump 16. Under the suction of the air pump 16, outside air enters the air duct 21 through the air inlet of the suction column 13, the air guide hole 15, and the air pump 16. The air duct 21 then compresses and opens the one-way valve of the air inlet of the second airbag 22, delivering the gas to the second airbag 22. Inside the second airbag 22, both the first pressure valve 23 and the second pressure valve 24 are closed until the second airbag 22 inflates to its maximum. At this point, the air pressure in the air duct 21 is equal to the air pressure in the second airbag 22, which in turn pushes the first pressure valve 23 to open. The gas in the air duct 21 flows into the first chamber through the first pressure valve 23. Since the air pressure in the second airbag 22 is greater than the air pressure in the air duct 21, the gas in the second airbag 22 tends to flow towards the air duct 21. At this time, the one-way valve at the air inlet of the second airbag 22 closes, allowing external gas to enter the first chamber formed by the square shell 11, the diverter plate 12, and the charging column 3.

[0037] Then, outside air flows into the second cavity 10 through the through holes on the surface of the diverter plate 12, thereby carrying away the heat generated by the charging components in the second cavity 10 during operation. The hot air passing through the second cavity 10 flows into the deep hole of the charging column 3 through the through holes. Then, the hot air is blown to the outer side of the air guide truncated cone 8 through the through holes of the support ring 4. The outer side of the air guide truncated cone 8 guides the hot air to the periphery of the bottom of the cylinder 1, and also blows the moisture in the middle of the cylinder 1 to the periphery. Then, the hot air and moisture flow upward along the cylinder wall of the cylinder 1 until they reach the cylinder cover 2. The hot air pushes open the one-way exhaust port 14 and flows to the outside. The outside air carries away the heat generated during the use of this device and the moisture underground. While cooling the device, it also prevents moisture from condensing into water droplets in the cylinder 1 and corroding the cylinder wall of the cylinder 1.

[0038] After the user finishes charging and places the charging cable in the second cavity 10, the control terminal starts the first motor 6, which drives the large lead screw 7 to rotate. The transmission ring 9 and the support ring 4 both move downward, which in turn drives the charging column 3 to move downward until the charging column 3 descends to the bottom of the cylinder 1. At this point, the control terminal stops the first motor 6. After the user finishes charging, the device moves downward to the ground under the control of the control terminal. This saves ground space and improves space utilization without affecting the charging effect.

[0039] When charging is finished and the device is moved underground, heat still remains in the second cavity 10. Therefore, the control terminal controls the air pump 16 to continue working, continuously using wind power to transport the remaining heat in the second cavity 10 and the moisture in the cylinder 1 to the outside.

[0040] When there is standing water on the ground, the air inlet of the suction column 13 needs to extend a certain distance above the ground for the device to draw air and dissipate heat. Therefore, as the water level rises and gradually submerges the air inlet of the suction column 13, the standing water enters through the air inlet, causing the float 17 to move upward under the buoyancy of the water. This moves the first piston 18, the sealing truncated cone 19, and the first airbag 20 upward together until the upper side of the float 17 contacts the upper side of the air inlet of the suction column 13. And it is covered. When external water droplets enter through the air inlet of the suction column 13 and are drawn upward by the air pump 16, the water droplets will hit the lower side of the float plate 17 due to inertia, thus preventing external splashing water droplets from being sucked into the air guide hole 15. At this time, external air enters the air pump 16 through the groove on the upper side of the float plate 17, the air inlet of the suction column 13, and the air guide hole 15. When the external water level continues to rise, but the float plate 17 is limited by the suction column 13 and cannot move upward, the float plate 17 will float upward. As the buoyancy of the water on the float plate 17 increases, it pushes the first piston 18 upward and compresses the spring between the float plate 17 and the first piston 18. At this time, the space between the float plate 17 and the first piston 18 gradually decreases, and the hydraulic oil squeezed inside flows along the through hole of the float plate 17 to the first airbag 20, causing the first airbag 20 to expand and block the air inlet of the suction column 13. When the external water level drops, the buoyancy of the float plate 17 gradually decreases. At this time, the first piston 18 moves downward under the action of the spring between it and the float plate 17, and the volume between the float plate 17 and the first piston 18 increases. The hydraulic oil in the first airbag 20 gradually flows between the float plate 17 and the first piston 18, releasing the blockage of the air inlet of the suction column 13 by the first airbag 20. When the external water level is higher than the position of the air inlet of the suction column 13, the suction column 13 is blocked by the float plate 17, the first piston 18 and the first airbag 20 to prevent external water from flowing into the device and causing damage to the charging equipment.

[0041] When leaves, plastic bags, or other debris drift to the suction column 13 and block its air inlet, the suction force of the air pump 16 remains unchanged. As the amount of air that can enter through the air inlet of the suction column 13 decreases, the pressure inside the air inlet and air guide hole 15 of the suction column 13 decreases and eventually forms a negative pressure. At the same time, the pressure at the air duct 21 decreases, and the first pressure valve 23 closes. At this time, the second pressure valve 24 is pushed upward by the air pressure inside the second airbag 22 and pulled upward by the negative pressure inside the air guide hole 15, causing the second pressure valve 24 to open. The high-pressure gas inside the second airbag 22 flows through the duct and air guide hole 15 to the air inlet of the suction column 13. The high-pressure gas in an instant blows away the leaves, plastic bags, and other debris adsorbed near the air inlet of the suction column 13 to the lower right.

[0042] Example 2: Based on Example 1, as shown in Figure 8, a buffer mechanism is also included on the charging post 3. This buffer mechanism reduces the hard impact force on the charging post 3 when a vehicle runs over it. The buffer mechanism includes a second piston 25, which is slidably connected to the lower side of the charging post 3. A cavity is formed at the rear of the lower side of the charging post 3, and the second piston 25 is located within this cavity. A support slide rod 26 is fixedly connected to the lower side of the second piston 25. The support slide rod 26 is slidably connected to the charging post 3, passes through the cavity of the charging post 3, and is fixedly connected to a pad 27. A spring connects the pad 27 to the charging post 3 to drive the charging post 3 back to its original position. An external communication device is installed on the upper side of the cavity of the charging post 3. The one-way valve 28, the distance between the support ring 4 and the transmission ring 9 is equal to the sum of the thickness of the pad 27 and the length of the support slide rod 26 protruding from the charging post 3, the cavity of the charging post 3 is provided with an L-shaped through hole communicating with the outside, and the area of ​​the L-shaped through hole is smaller than the area of ​​the one-way valve 28, the square shell 11 is fixedly connected to the support rod 29, both the support rod 29 and the square shell 11 are slidably connected to the suction column 13, the support rod 29 and the suction column 13 are connected by a spring, the top of the charging post 3 is fixedly connected to the protective ring 2901, which is used to prevent the car from directly running over the charging post 3. By retracting the device into the cylinder 1 before the vehicle runs over it, the spring between the charging post 3 and the pad 27 is used for buffering, so as to avoid damage to the device from hard impact.

[0043] As shown in Figures 2, 9, and 10, a sealing mechanism is also included on the cylinder cover 2. This sealing mechanism prevents rainwater from flowing into the cylinder 1. The sealing mechanism includes a transmission rod 30, which is slidably connected to the left rear side of the air guide frustum 8. A spring connects the transmission rod 30 and the air guide frustum 8, used to push the transmission rod 30 back to its original position, releasing the compression ring 31 from the third airbag 32. The transmission rod 30 and the transmission ring 9 are in a compression fit, used to push the compression ring 31 to move and compress the third airbag 32. The upper end of the transmission rod 30 is fixedly connected to the compression ring 31. Both the compression ring 31 and the transmission rod 30 are slidably connected to the cylinder cover 2. The third airbag 32 is located inside the cylinder cover 2. The third airbag 32 is fixed to the inner side of the cylinder cover 2. The third airbag 32 contains hydraulic oil. The third airbag 32 cooperates with the charging column 3 to seal the cylinder cover 2 and the charging column 3. The compression ring 31 is in compression cooperation with the third airbag 32 to deform the third airbag 32 so that it fits more closely to the side wall of the charging column 3. The start and stop of the first motor 6 is controlled by the control terminal, which drives the compression ring 31 to compress the third airbag 32, so that the third airbag 32 fits tightly to the side wall of the charging column 3, effectively preventing external water from flowing into the device through the gap between the charging column 3 and the cylinder cover 2, causing corrosion inside the device.

[0044] When this device is underground, it needs to absorb air for heat dissipation, so the top of the device will be slightly above the ground, which may cause it to be run over by passing cars. When a car runs over it, the wheel first contacts the protective ring 2901, squeezing the protective ring 2901 to move downward quickly. The charging column 3 moves downward, and at this time the pad 27 contacts the bottom of the cylinder 1. The second piston 25 slides upward relative to the charging column 3 and compresses the spring between the pad 27 and the charging column 3. The gas in the cavity of the charging column 3 is squeezed by the second piston 25 and flows to the outside through the one-way valve 28 and the L-shaped through hole. When the wheel moves to the side of the suction column 13, it squeezes the suction column 13 to move downward and compresses the spring between it and the support rod 29.

[0045] After the wheel moves over the device, the suction column 13 returns to its initial position under the action of the spring between it and the support rod 29. The charging column 3 moves upward under the action of the spring between it and the pad 27, which drives the second piston 25 to move downward relative to the charging column 3. At this time, the one-way valve 28 is closed and the area of ​​the L-shaped through hole is small, which causes the speed at which outside air enters the cavity of the charging column 3 to not keep up with the speed at which the volume of the cavity of the charging column 3 increases. This reduces the pressure in the cavity of the charging column 3, preventing the second piston 25 from moving downward. This causes the charging column 3 to move upward slowly, preventing the rear wheel from running over the device again.

[0046] After the device finishes charging and moves downward to its initial position, the pad 27 contacts the bottom surface of the cylinder 1. The charging column 3 stops moving downward under the action of the spring between it and the pad 27. At this time, the control terminal controls the first motor 6 to continue rotating, driving the large lead screw 7 to rotate. Then, the transmission ring 9 moves downward until it contacts the transmission rod 30. As the transmission ring 9 moves downward, it drives the transmission rod 30 to move downward together and compress the spring between it and the air guide truncated cone 8. The transmission compression ring 31 moves downward and compresses the third airbag 32 through the inclined surface. The hydraulic oil in the third airbag 32 is compressed, causing the third airbag 32 to move inward and finally contact the side wall of the charging column 3. When the transmission ring 9 contacts the truncated cone of the air guide truncated cone 8, the control terminal stops the first motor 6. At this time, the third airbag 32 and the charging column 3 are tightly fitted, effectively preventing external water from flowing into the device through the gap between the charging column 3 and the cylinder cover 2, causing corrosion inside the device.

[0047] Example 3: Based on Example 2, as shown in Figures 11-13, it further includes a scraping mechanism disposed on the cylinder 1. The scraping mechanism is used to discharge the condensed water droplets inside the cylinder 1 to the outside. The scraping mechanism includes a second motor 33, which is installed on the right side inside the first cavity 5. The control terminal is electrically connected to the second motor 33. The contact position between the cylinder 1 and the cylinder cover 2 is an inclined surface. The output shaft of the second motor 33 is fixedly connected to a small lead screw 34. The output shaft of the second motor 33 is rotatably connected to the cylinder 1 to drive the cylinder. The mounting ring 36, rubber ring 37, transmission slide rod 38, positioning ring 39, and inclined ring 40 move up and down. A positioning rod 35 is fixedly connected to the left side inside the cylinder 1. The positioning rod 35 and the small lead screw 34 are symmetrically distributed. The small lead screw 34 is threadedly connected to the mounting ring 36. The mounting ring 36 is slidably connected to the positioning rod 35. Both the small lead screw 34 and the positioning rod 35 are located inside the mounting ring 36. A rubber ring 37 is fixedly connected to the mounting ring 36. The outer diameter of the rubber ring 37 is equal to the inner diameter of the cylinder 1, used to completely scrape away water droplets from the inner wall of the cylinder 1. The cylinder 1 is slidably connected to the cover 2 by two symmetrically distributed transmission slide rods 38. Both the cover 2 and the cylinder body 1 are fitted with the transmission slide rods 38 to switch the contact state between the rubber ring 37 and the cylinder body 1. A positioning ring 39 is fixed to the upper end of each transmission slide rod 38, and a beveled ring 40 is fixed to the lower end of each transmission slide rod 38. The side of the beveled ring 40 has the same curvature as the rubber ring 37. Both the positioning ring 39 and the beveled ring 40 are press-fitted with the rubber ring 37 to control the contact state between the rubber ring 37 and the cylinder body 1. The cylinder body 1 and the cover 2 are slidably connected, and... A tension spring connects the cylinder body 1 and the cylinder cover 2. There is damping between the mounting ring 36 and the transmission slide rod 38. The damping between the mounting ring 36 and the transmission slide rod 38 is greater than the tension of the tension spring between the cylinder body 1 and the cylinder cover 2 at the beginning. This ensures that the rubber ring 37 is released from contact with the cylinder body 1 only after the water droplets inside the device are discharged to the outside. By starting the second motor 33, the transmission mounting ring 36 moves upward, scraping away the water droplets inside the cylinder body 1 and discharging them to the outside. This prevents the device from short-circuiting due to water droplets forming inside the cylinder body 1 caused by moisture.

[0048] The control terminal intermittently starts the second motor 33, which drives the small lead screw 34 to rotate. The transmission mounting ring 36 moves upward. Initially, the lower side of the inclined ring 40 is close to the bottom of the cylinder 1 and its upper inclined side is close to the lower side of the rubber ring 37. This supports the outer side of the rubber ring 37 to contact the inner wall of the cylinder 1, preventing water droplets from condensing and flowing to the bottom of the cylinder 1 below the rubber ring 37. When the mounting ring 36 moves upward, it drives the rubber ring 37 to move and continuously contact the side wall of the cylinder 1, scraping the water droplets off the side wall of the cylinder 1 and collecting them at the angle formed by the rubber ring 37 and the side wall of the cylinder 1.

[0049] When the mounting ring 36, rubber ring 37, transmission slide rod 38, positioning ring 39, and inclined ring 40 move to the upper part of the small lead screw 34, and the transmission slide rod 38 contacts the lower side of the cylinder cover 2, as the small lead screw 34 continues to rotate, it drives the mounting ring 36, rubber ring 37, transmission slide rod 38, positioning ring 39, inclined ring 40, and cylinder cover 2 to move upward, stretching the tension spring between the cylinder cover 2 and the cylinder body 1. As the cylinder cover 2 moves upward, the tension of the tension spring between the cylinder cover 2 and the cylinder body 1 gradually increases until the tension of the tension spring between the cylinder cover 2 and the cylinder body 1 is greater than the damping between the mounting ring 36 and the transmission slide rod 38. At this time, the lowermost side of the rubber ring 37 is on the same horizontal plane as the inclined surface on the upper side of the cylinder body 1, and the cylinder cover 2 no longer moves upward under the tension of the tension spring between it and the cylinder body 1. As the small lead screw 34 continues to rotate, it drives the mounting ring 36, rubber ring 37, transmission slide rod 38, positioning ring 39, inclined ring 40, and cylinder cover 2 to move upward. The moving mounting ring 36 presses against the transmission slide rod 38, causing the transmission slide rod 38 to slide downward relative to the mounting ring 36. This drives the positioning ring 39 and the inclined ring 40 to move downward. The inclined ring 40 no longer supports the rubber ring 37. At the same time, the positioning ring 39 presses the rubber ring 37 downward, causing the rubber ring 37 to retract within the positioning ring 39 and lose contact with the cylinder 1. At this time, the control terminal starts the second motor 33 in reverse, driving the mounting ring 36, rubber ring 37, transmission slide rod 38, positioning ring 39, and inclined ring 40 to move downward until the inclined ring 40 contacts the bottom of the cylinder 1 and presses the inclined ring 40 upward. This causes the positioning ring 39 to release the retraction of the rubber ring 37. At the same time, the inclined ring 40 re-contacts the rubber ring 37 and expands the rubber ring 37, allowing the rubber ring 37 to contact the inner wall of the cylinder 1.
