Description

Technical Field

[0001] This invention relates to the field of lifting charging piles, specifically a lifting, sun-proof, and light-avoiding charging pile. Background Technology

[0002] Existing charging stations are typically installed vertically in designated locations. Exposure to direct sunlight accelerates the aging of the charging station's wiring and casing, potentially leading to electrical leaks and safety accidents. Adding sunshades increases installation costs, and numerous charging stations and sunshades occupy roadside space, exacerbating urban congestion. A better solution is to use retractable charging stations. These are installed underground and raised when needed, providing shade to prevent accelerated aging of the wiring and casing from sun exposure while saving urban space.

[0003] Existing lifting charging piles are often submerged underground, where the harsh underground environment easily leads to the accumulation of water and dust. The transmission structure of these piles is prone to jamming due to dust and corrosion. Once the transmission mechanism is damaged, the charging pile cannot be raised and used normally. For example, a buried charging pile with application number CN202020394756.X uses a motor and gear set to drive the lifting of the charging pile in order to solve the problem of aging caused by exposure to sunlight. However, the use of motors, gear sets, and other transmission devices and mechanisms in the underground environment is easily damaged by the harsh conditions such as rain, humidity, and heat. Moreover, the replacement of motors and gears is complex and costly, which is not conducive to the large-scale installation and promotion of charging piles. The invention, with application number CN202210264809.X, describes a lifting-type sun-protected charging pile. While aiming to address the problem of accelerated aging caused by sun exposure, the invention utilizes gears and racks in conjunction with a parked vehicle. The movement of the vehicle during parking drives the charging pile to rise and fall. However, the gear and rack system is costly to manufacture and maintain, and is prone to jamming. Furthermore, in underground environments, the gears and racks are susceptible to rust and damage due to moisture and dust, leading to unstable transmission and reduced effectiveness of the lifting-type charging pile.

[0004] Many existing charging piles are not very large or heavy; some, for example, are only 25x11x30cm in length, width, and height. They do not require complex structures such as motors, gears, or hydraulic rods, and their raising and lowering can be easily controlled manually. Therefore, this paper proposes a lifting-type, sun-protected charging pile. Using simple structural components, it can be used in harsh environments such as underground locations. This reduces the possibility of the charging pile getting stuck due to rust or dust during raising and lowering, improving its adaptability to practical environments and facilitating its widespread adoption. Simultaneously, while achieving the raising and lowering function to reduce ground installation space and preventing the charging pile from aging due to sun exposure, the paper also aims to minimize the cost of processing and replacement of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a liftable, sun-protected charging pile. By setting up a manually controlled lifting device, the charging pile is installed underground and can be manually lifted when needed. This reduces the space occupied by the charging pile, prevents it from aging due to sun exposure, simplifies the structure of the lifting device, makes it easy to replace, reduces maintenance costs, and can adapt to the harsh underground environment, improving the stability of the lifting device and ensuring the stability of the charging pile during lifting and use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A retractable, sun-protected charging station includes:

[0008] The charging pile body is used to provide charging services for new energy vehicles.

[0009] A pit is dug in the ground, and the bottom of the pit is connected to the municipal drainage system via drainage pipes to prevent rainwater from seeping in and accumulating. The charging pile body is horizontally installed inside the pit. A lifting device is installed at the bottom of the charging pile body. The lifting device includes a lower platform and an upper platform located under the charging pile body. The upper platform and the lower platform are arranged horizontally and parallel to each other. Each side of the upper platform is provided with a connecting rod 1 and a connecting rod 2. Both connecting rod 1 and the two connecting rod 2 can be made of stainless steel, weathering steel, or ordinary steel with an anti-rust coating. The middle of each connecting rod 1 and connecting rod 2 is hinged together like scissors. Each side of the upper platform has a sliding groove 1. The lower platform... Both left and right sides have slide grooves two identical to slide groove one. One end of each of the two connecting rods one is rotatably mounted on a pivot on the upper platform. The other ends of the two connecting rods one are slidably mounted in the two slide grooves two on the lower platform via pins. A round rod one is installed between the ends of the two connecting rods one mounted in the slide grooves two, connecting the ends of the two connecting rods one in the slide grooves two. This ensures that the two connecting rods one slide synchronously within the two slide grooves two, preventing the upper platform from tilting or jamming during movement due to asynchronous sliding of the two connecting rods one. One end of each of the two connecting rods two is slidably mounted in the two slide grooves one. A pin is installed between the ends of the two connecting rods two mounted in the slide grooves one. Round rod two, like round rod one, connects one end of two connecting rods two within the sliding groove one, similarly preventing asynchronous sliding of the two connecting rods two. The other ends of both connecting rods two are rotatably mounted on the pivot of the lower platform. A cover plate, made of ductile iron, is also fixedly installed on the upper platform. The cover plate covers the top, back, and left and right sides of the charging pile body. The side length of each side of the top cover plate is 2-3 cm longer than the side length of each side of the pit. The edge of the pit floor also has a recess that matches the top cover plate, so that the upper surface of the top cover plate is flush with the ground surface when the charging pile body is completely submerged. The cover seals the pit opening. The top cover ensures that people won't step directly on the charging pile when it's lowered into the ground, and minimizes dust and rainwater entering the pit. The cover also prevents the charging pile from being directly exposed to sunlight. The side and top covers effectively prevent direct sunlight during the charging process when the charging pile is raised to charge the vehicle. Each surface of the cover is spaced 3-5cm from the charging pile to ensure heat dissipation. Small holes can also be made in the cover to facilitate heat dissipation during operation, and to prevent heat from being directly transferred to the charging pile during sun exposure, thus preventing it from aging prematurely.It is important to note that the lower platform can use a perforated steel plate to reduce material consumption, provided it functions correctly. The upper platform, however, must use a flat steel plate without any perforations to prevent debris from falling into the lower platform through any openings and affecting its movement. A drive device is also provided on one side of the lower platform. This drive device can be a hydraulic cylinder, a pressure cylinder, a connecting rod, or other devices or mechanisms capable of driving horizontal movement. Connecting rods one and two are arranged on the left and right sides of the upper and lower platforms. The drive device can drive one end of connecting rod two in sliding groove one to move horizontally within sliding groove one, or drive one end of connecting rod one in sliding groove two to move horizontally within sliding groove two, or directly drive the upper platform up and down, thus enabling the charging pile body to move. The charging station moves up and down, allowing it to be hidden underground when not in use. A cover prevents the charging station from being stepped on or exposed to direct sunlight. When in use, a drive mechanism raises the upper platform, ultimately lifting the charging station out of the ground for charging new energy vehicles. The three-sided cover prevents direct sunlight exposure, thus preventing the charging station from aging prematurely. Furthermore, the linkage-based lifting mechanism is simpler than gear and rack systems, resulting in lower production, replacement, and maintenance costs. It also requires less precision during installation and is less susceptible to wear and jamming from dust and debris, unlike gear and rack systems.

[0010] Preferably, the driving device includes a vertically formed slide groove three on the side of the lifting device. The round rod one is horizontally inserted into the slide groove three and can move horizontally within the slide groove three. A pull rod is provided inside the slide groove three. One end of the pull rod is hinged to the bottom of the slide groove three. The pull rod is in contact with and tangent to the round rod one. When the pull rod swings within the slide groove three, it can drive the round rod one to slide left and right within the slide groove three. The other end of the pull rod extends out of the slide groove three. The distance from the end of the pull rod extending out of the slide groove three to the contact point with the round rod one is greater than the distance from the bottom of the pull rod in the slide groove three to the contact point with the round rod one. When in use, the user pulls the lever from the initial position along slide groove three. The lever then swings in a fan shape inside slide groove three. As the lever swings, the round rod one moves horizontally along slide groove two. The horizontally moving round rod one will cause one end of the two connecting rods one to move horizontally closer to one end of the two connecting rods two. At this time, the two connecting rods one and two, which are hinged together at the midpoint, will cause the upper platform to move horizontally upward. The charging pile body, which is fixedly installed on the upper platform, also moves horizontally upward with the upper platform and finally rises out of the ground. The reason for using a manually operated lever to move the charging pile up and down instead of using cylinders, motors, or hydraulic cylinders as a power source is that the charging pile needs to be located underground for extended periods. The underground environment is complex and more susceptible to dust and moisture than charging piles that are normally placed on the ground. Motors, cylinders, and hydraulic cylinders are more prone to damage, and their production, installation, and maintenance costs are much higher than those of linkage drives. In addition, there are also smaller charging piles available. The lever, combined with its design, provides a labor-saving lever, allowing for easy manual movement of the charging pile. Furthermore, the lever has low maintenance and production costs and is easily replaceable. Using a lever and manual drive can save significant costs while still achieving the intended function.

[0011] Furthermore, a handle is slidably installed on the upper end of the lever. The upper end of the lever adopts a hollow design, and the handle is inserted into the inside of the lever. When not in use, the handle slides into the lever due to its own weight, reducing the height of the lever protruding from the ground and avoiding occupying too much ground space. When in use, the handle can be pulled out from the inside of the lever before pulling, which can further lengthen the effort-saving lever, making it easier for users to raise the charging pile body. At the same time, it can automatically slide into the inside of the lever when not in use to save space.

[0012] Alternatively, the pull rod is slidably installed within the slide groove three, and the pull rod is directly vertically welded to either round rod one or round rod two. Compared to the aforementioned swing-type pull rod, the welded pull rod can only move linearly, and the slide groove three required for the swing-type pull rod is relatively long. Using a welded linear pull rod can greatly reduce the required length of the slide groove three. However, the linear pull rod cannot save effort, which may be difficult for some users with less strength. Considering that the main body of a small charging pile weighs about 8-10kg, most adults can pull it without using a lever to save effort. This method can be considered for places with limited space.

[0013] Preferably, a locking device is provided above the slide groove three to prevent the drive device from being accidentally opened. The locking device includes a housing one horizontally arranged on the side of the slide groove. A locking tongue one is slidably installed inside the housing. A ramp is provided on the upper side of the locking tongue one. One end of the locking tongue one extends out of the housing one. A spring one is provided at one end of the locking tongue one. The spring one is located inside the housing one. In the normal state, the spring one tightly presses against the locking tongue one, so that the locking tongue one is kept in the state of extending out of the housing one. The part of the locking tongue one extending out of the housing one crosses the slide groove three. One side of the locking tongue one is inclined. A pressure block is vertically slidably installed above the locking tongue one. The lower end of the pressure block is inclined in coordination with the ramp of the locking tongue one. When the latch is not retracted into the outer shell, the lever cannot pass the latch, and the charging pile cannot be raised. Only when the pressure block is pressed down manually will the pressure block move vertically downward. During the movement, the ramp on the latch will be pushed towards the inside of the outer shell, and the latch will also move towards the inside of the outer shell. The spring will be compressed, and the person can then pull the lever to raise the charging pile. When the person releases the pressure block, the spring will drive the latch to extend out of the outer shell. When the charging pile falls back down, the weight of the charging pile, combined with the tilt of one side of the latch, will press the latch back into the inside of the outer shell, achieving automatic return without the need for manual pressing of the latch back into the outer shell. To prevent accidental pushing of the lever, which could cause the charging station to rise and fall unstably, the lever can only be pulled after pressing the block to raise the charging station. This avoids exposing the charging station to sunlight when not in use, which could accelerate the aging of its parts. It also prevents debris from accidentally entering the raised charging station, thus improving the stability and practicality of the equipment.

[0014] Preferably, the side of the slide rail three is also provided with a locking device two for ensuring that the upper platform of the charging pile body is always at its highest point during charging. The locking device two includes a housing two fixed to the side of the slide rail three. A locking tongue two is slidably installed inside the housing two. One side of the locking tongue is inclined. A spring two is provided on the side of the locking tongue two inside the housing. An automatic unlocking device is also installed on the housing two. The locking tongue two is kept extended under the action of the spring two. When the pull rod is pulled to move and drive the charging pile body to rise, the pull rod squeezes the inclined surface of the locking tongue two, and the locking tongue two is forced towards The inner part of the outer shell is squeezed out, and the second spring is compressed. After the pull rod passes the locking tongue, the second spring returns to its original state and the second locking tongue pops out of the outer shell again to block the pull rod, preventing the pull rod from resetting due to the gravity of the charging pile body and preventing the charging pile body from falling back to the ground, keeping it on the ground for easy use by the user. The automatic unlocking device is an electromagnet, which is electrically connected to the charging pile body. When the user finishes using the charging pile body, the charging pile body controls the electromagnet to be energized, the electromagnet generates magnetism and pulls the locking tongue back into the inner part of the outer shell. At this time, under the action of the weight of the charging pile body, the charging pile body descends back below the ground to avoid light, and the pull rod will be reset. By utilizing the locking tongue, electromagnet, and spring in conjunction with each other, the charging pile body is stably kept above the ground while charging a car, preventing it from falling and damaging the charging cable. Furthermore, the electromagnet, working in tandem with the charging pile body, ensures that it falls automatically after charging is complete, avoiding the risk of accidental descent and trapping a person. It also prevents users from forgetting to retract the charging pile body after charging, thus improving the safety, stability, and automation of the equipment, while maintaining a simple and compact structure.

[0015] Preferably, the buffer device includes a cylinder horizontally mounted at one end of the slide groove. A piston is slidably mounted inside the cylinder, and a push rod is fixedly mounted on the piston. The push rod extends from one end of the cylinder. The cylinder has two circular holes located at its two ends. The diameter of the circular hole at the end of the cylinder where the push rod does not extend does not exceed 3 mm, and the diameter of the circular hole at the other end can be 2 to 3 times that of the circular hole at the end of the cylinder where the push rod does not extend. The piston end of the push rod is movably connected to the pull rod via a circular sleeve. A one-way valve is provided at the other end of the cylinder. The one-way valve only allows gas to be drawn into the cylinder from the outside and does not allow gas inside the cylinder to be discharged from the one-way valve. The one-way valve is located at the end of the cylinder where the push rod does not extend. When the charging pile body falls, the pull rod is pressed back to its initial position by the round rod. At this time, the pull rod will squeeze the push rod, which will drive the piston to discharge the gas inside the cylinder through the small round hole. Because the amount of gas discharged through the round hole is limited, even if the charging pile body falls suddenly, the upper platform will not hit the lower platform at a high speed, and there will be no impact. Instead, it will fall slowly to avoid damage to the charging pile body due to impact, thus improving the stability of the equipment. The function of the one-way valve is that when the user pulls the pull rod to raise the charging pile body, the pull rod drives the push rod and piston to move through the annular sleeve. The piston needs to discharge the air on one side of the direction of the pull rod movement and draw the air into the cylinder on the other side. The one-way valve makes it more convenient and less strenuous for the user to pull the pull rod to raise the charging pile body, thus improving the practicality of the equipment.

[0016] Alternatively, a cylinder can be replaced with a hydraulic cylinder. Simply make a small hole in the piston to connect the two sides of the hydraulic cylinder. There is no need to install a check valve, and there is no need to worry about dust or other debris clogging the check valve and the small hole. There is also no risk of dust entering the cylinder and causing wear on the cylinder wall and piston. However, hydraulic cylinders require higher sealing performance and are prone to leakage in outdoor environments, which makes the production and maintenance costs higher than those of cylinders. Users can consider this option according to their specific circumstances.

[0017] Preferably, a dustproof device is provided above the slide groove three to prevent debris from falling into the slide groove three and interfering with the movement of the pull rod. The dustproof device includes a slide groove four horizontally opened on the slide groove three. The slide groove four is flat, and two baffles are slidably and horizontally installed inside the slide groove four. The ends of the two baffles that are close to each other are arc-shaped, and the other ends of the two baffles are provided with springs three. The two springs three press the two baffles together, so that the two baffles are close to each other. The arc-shaped ends of the two baffles cooperate with the pull rod to cover the pull rod. When the pull rod moves along the slide groove three, the pressure plates on both sides also move left and right inside the slide groove four with the pull rod under the action of the two springs three. At the same time, due to the action of the two springs three, the two baffles are always in close contact with the pull rod during the movement of the pull rod, effectively preventing dust from entering the interior of the slide groove three and avoiding dust and other debris from falling into the slide groove three and hindering the movement of the pull rod.

[0018] Optionally, both baffles can be made by hinged together small sections of steel, similar to how many hinges are hinged together. These baffles are then hinged to the pull rod and both ends of the slide rail. When the pull rod moves left and right, one baffle folds up, while the other baffle lies flat to prevent dust from entering. This method of baffle manufacturing is more complex. Furthermore, the repeated rubbing of the sidewalls of the slide rail during the flattening and folding process causes some wear. When the wear gap becomes too large, sand and dust can enter the interior of the slide rail. However, compared to two flat baffles, this method has the advantage of not requiring a long installation space, and installation and replacement are more convenient.

[0019] Alternatively, the two baffles can also be made of soft plastic or rubber, and the installation method is the same as that of baffles made of small steel sheets. The advantage of using plastic or rubber is that the production and processing are more convenient and cheaper than the above two methods, and the installation is also more convenient. The disadvantage is that although plastic products have better flexibility, their wear resistance is poor. Under the condition of sun exposure, the aging of plastic will be accelerated, and it is necessary to check and replace them frequently.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The lifting-type sun-shielding charging pile of the present invention, compared with existing lifting-type sun-shielding charging piles, achieves the same sun-shielding function by using a pull rod in conjunction with connecting rod one and connecting rod two. When the pull rod moves inside the sliding groove three, it will drive the scissor-shaped connecting rod one and connecting rod two. The approach and separation of the ends of connecting rod one and connecting rod two will drive the upper platform to rise and fall. It does not require gear and rack transmission, is not prone to jamming like gear and rack, does not require frequent lubrication like gear and rack, and is not prone to leakage like hydraulic rods. The structure is simple and compact, the parts are highly replaceable, the processing is simple, the assembly precision requirements are low, the maintenance cost is low, the environmental adaptability of the lifting charging pile is improved, and the stability of the equipment is ensured.

[0022] 2. The lifting-type sun-proof charging pile of the present invention is equipped with a buffer device. It utilizes the interaction between the cylinder piston and the round hole on the cylinder. During the descent of the charging pile, the pull rod presses the push rod of the cylinder, and the gas cannot be quickly discharged from the cylinder through the round hole. This ensures that the charging pile descends as slowly and smoothly as possible, preventing damage caused by collisions and impacts from rapid descent. This improves the practicality of the equipment. The cylinder has holes at both ends, and the requirements for airtightness and other aspects of the cylinder are not high. It is more stable than spring buffer and does not have the high sealing requirements of hydraulic buffer. It saves costs as much as possible while achieving stable buffering.

[0023] 3. The lifting-type sun-proof charging pile of the present invention is equipped with a locking device one and a locking device two. Locking device one ensures that the charging pile will not move up and down due to unintentional collisions with the pull rod, and minimizes the risk of dust and debris entering the pit and damaging the equipment during the process of the cover plate on the charging pile being raised above the ground, thus improving the stability of the equipment. Locking device two keeps the charging pile in a raised state when the user is using the charging pile. It is also equipped with an unlocking device that automatically unlocks locking device two. The unlocking device is an electromagnet. The charging pile controls the electromagnet. When the user finishes charging, the charging pile automatically controls the electromagnet to be energized. After the electromagnet unlocks locking device two, the charging pile automatically descends under its own weight, improving the automation level of the equipment. This avoids the charging pile being exposed to the sun for a long time after the user forgets to return it to its original position after charging, which would accelerate the aging of the charging pile. At the same time, the charging pile can only sink into the ground after charging is completed, avoiding the charging pile sinking into the ground during the charging process due to human error, which could cause the charging cable to be caught, further improving the stability of the equipment.

[0036] Example 1:

[0037] refer to Figures 1 to 11The upper platform 3 and the lower platform 2 are rectangular and the same size. The lower platform 2 is hollowed out to reduce material consumption, while the upper platform 3 remains intact. A pit is dug in the ground that is 3-5mm larger in length and width than the upper and lower platforms 2. A pipe is installed at the bottom of the pit to connect with the municipal drainage system to prevent rainwater from accumulating in the pit and reducing the lifespan of the parts. A sliding groove 3 11 is cut on the side of the pit, and the pit and sliding groove 3 11 are connected at the bottom. First, the lower platform 2 is horizontally fixed to the bottom of the pit with bolts. Then, a round rod 1 8 is horizontally passed through the two sliding grooves 2 7 on the lower platform 2. The round rod 1 8 can slide horizontally inside the two sliding grooves 2 7, and one end of the round rod 1 8 extends horizontally through the sliding groove 3 11. A tie rod 12 is rotatably installed in the sliding groove 3 11. The tie rod 12 is located on the round rod On the lower side of rod 8, the other end of pull rod 12 extends out of slide groove 3 11. Pulling pull rod 12 along slide groove 3 11 can drive rod 8 to move horizontally along slide groove 2 7. A handle 17 is slidably installed on one end of pull rod 12 extending out of slide groove 3 11. Then, the two pull rods 12 are rotated and installed on rod 8. Then, two connecting rods 2 5 are rotated and installed on the lower platform 2. The length of the two connecting rods 2 5 is the same as the length of the two connecting rods 1 4. The two connecting rods 2 5 are respectively hinged to the two connecting rods 1 4 at the midpoint. A round rod 2 9 is horizontally slidably installed on the upper platform 3. The round rod 2 9 passes through two slide grooves 1 6. The other end of connecting rod 2 5 is rotated and installed on the round rod 2 9. The other end of connecting rod 1 4 is rotated and installed at the bottom of the upper platform 3. The upper platform 3 and After the lower platform 2 is installed, it is level with the ground. The charging pile body 1 is bolted onto the upper platform 3. A cover plate 10 is also bolted onto the upper platform 3. The cover plate 10 is a four-sided surround cover plate 10, which protects the left, right, back, and top surfaces of the charging pile body 1 to prevent direct sunlight from accelerating the aging of the charging pile body 1. Each cover plate 10 is 3-5cm away from the charging pile body 1. The length and width of the top cover plate 10 are 10% larger than the length and width of the upper and lower platforms. The opening of the pit has a groove that matches the top plate of the cover plate 10. When the charging pile body 1 is completely sunk into the ground, the top plate of the cover plate 10 sinks into the groove at the opening of the pit, and then the upper surface of the top plate of the cover plate 10... The pit is flush with the ground to ensure complete enclosure, preventing dust and debris from entering and reducing rainwater infiltration. Two baffles 27, made of weathering steel, are slidably installed inside the slide groove 26. These baffles 27 are located on either side of the pull rod 12, with the contact points between the baffles 27 and the pull rod 12 being arc-shaped. Springs 28 are also installed inside the slide groove 26, located at the ends of the two baffles 27 that are not in contact with the pull rod 12. Next to the slide groove 11, a housing 13 is bolted and installed on one side of the slide groove 11 when the pull rod 12 is in its initial position. A locking tongue 14 is horizontally slidably installed inside the housing 13, and a spring 15 is also installed inside the housing, located at the tail end of the locking tongue 14.Spring 15 pushes one end of the latch 14 out of the outer casing 13. When the latch 14 extends out of the outer casing 13 under the action of spring 15, it can block the pull rod 12, preventing the pull rod 12 from swinging along the slide groove 11. The extended part of the latch 14 has a straight edge on one side and a beveled edge on the other. The straight edge prevents the pull rod 12 from swinging, while the beveled edge allows the pull rod 12 to press the latch 14 back into the outer casing 13, automatically returning it to its original position. A ramp is provided on the upper side of the latch 14, and a pressure block 16 is also vertically slidably installed on the outer casing 13 to press... The lower part of block 16 is inclined, and the inclination of block 16 cooperates with the slope of latch 14. When block 16 is pressed, latch 14 can compress spring 15 and retract into the outer shell 13. The other side of the slide groove 3 11 opposite to the outer shell 13 is fixed to the outer shell 22 with bolts. The latch 23 is slidably installed inside the outer shell 22. One side of the latch 23 is inclined, and the other side is straight. Spring 24 is installed inside the outer shell 22 and is located at the tail end of latch 23. Spring 24 holds latch 23 in the extended position from outer casing 22. An electromagnet 25 is installed at the end of latch 23, electrically connected to and controlled by the charging pile body 1. A cylinder 18 is horizontally installed in a groove on one side of latch 14, with pull rod 12 as the dividing line. The cylinder 18 is cylindrical, and a piston 19 is slidably installed inside. A push rod 20 is threaded onto the piston 19, with the other end of the push rod 20 extending outside the cylinder 18. A circular sleeve is installed at the end of the cylinder 18. The pull rod 12 passes through the circular sleeve, and the pull rod 12 can drive the push rod 20 and piston 19 to move back and forth along the cylinder 18. Circular holes 21 are provided on both end faces of the cylinder 18. The circular hole 21 on the end face of the cylinder 18 where the push rod 20 extends is twice the size of the circular hole 21 on the other end. The smaller circular hole 21 has a diameter of 2mm. A one-way valve 29 is also installed on the end face of the cylinder 18 where the smaller circular hole 21 is located. The one-way valve 29 only allows gas to enter the cylinder 18 from the outside.

[0038] The specific workflow is as follows:

[0039] Before operation: The charging pile body 1 is sunk into the pit to avoid direct sunlight, which would cause the outer shell and cables of the charging pile body 1 to age faster.

[0040] During operation: The user parks the new energy vehicle next to the charging pile body 1 of this invention. The user gets out of the car and walks to the side of the lever 12. The user holds the handle 17 on the lever 12 with their right hand and pulls it out along the direction of the lever 12, thus lengthening the entire lever 12. After the lever 12 is lengthened, it will be easier for the user to pull the lever 12 due to the lever principle. Then, the user steps on the pressure block 16 on the outer shell 13 on the side of the slide groove 3 11 with their left or right foot. At this time, the pressure block 16 moves downward. The inclined bottom of the pressure block 16 will press against the ramp on the locking tongue inside the outer shell 13, causing the locking tongue 14 to retract into the outer shell, compressing the spring 15, and unlocking the locking device. At this time, the pull rod 12 can be pulled along the slide groove 3 11. The pull rod 12 drives the round rod 8 to move along the slide groove 2 7. The round rod 8 drives the end of the connecting rod 4, which is rotatably mounted on it, to move towards the end of the connecting rod 2 5 mounted on the lower platform 2. Then the entire upper platform 3 will rise horizontally. When the upper platform 3 rises, it will drive the charging pile. The main body 1 moves horizontally upwards. When the user pulls the lever 12, the lever 12 also drives the push rod 20 to move through the annular sleeve. The piston 19 draws in air from the smaller circular hole 21 and the one-way valve 29, and discharges gas from the larger circular hole 21. When the charging pile main body 1 is about to reach its highest point, the lever 12 will press the bevel of the locking tongue 23. The locking tongue 23 will slide back into the outer shell 22 because the bevel is pressed by the lever 12. After the lever 12 passes, the locking tongue 23 is... Under the action of spring 24, the lever 12 extends again, and then one straight edge of the locking tongue 23 blocks the lever 12, preventing the lever 12 from sliding back. At this time, the charging pile body 1 will not fall down due to gravity when the user releases it. During the sliding of the lever 12, the baffles 27 on both sides of the lever 12 are always pressed against the lever 12 by the arc end of the two baffles 27 under the action of the spring. The two baffles 27 move left and right with the lever 12, preventing dust, debris and other objects from falling into the groove and causing the lever 12 to jam. After the lever 12 is locked by the locking tongue 23 and the charging pile body 1 can no longer fall, the user can let go and walk to the front of the charging pile body 1. After letting go, the handle 17 on the lever 12 will fall back into the lever 12 under the action of gravity to reduce the space occupied. Take the charging gun from the charging pile body 1 and insert it into the charging interface of the new energy vehicle. During the charging process, the cover plate 10 will shield the charging pile body 1 from direct sunlight. After the charging is completed, pull the cable back into the range of the upper platform 3, and then insert the charging gun back into the charging pile body 1 and leave.After charging is complete, the charging pile body 1 will activate the electromagnet 25. The electromagnet 25 will pull the locking tongue 23 into the outer shell 22. At this time, due to the gravity of the charging pile body 1, the connecting rod 4 and connecting rod 5 will cause the upper platform 3 to descend. The round rod 8 will squeeze the pull rod 12 to reset it. The pull rod 12 will then drive the push rod 20 to move horizontally. Since the push rod 20 needs to discharge the gas in the cylinder 18 on the side where the one-way valve 29 is located during the movement, the one-way valve 29 cannot discharge the gas. The gas can only pass through the round rod with a smaller opening. The vent 21 is used for venting, so the movement speed of the piston 19 and push rod 20 will slow down, and the movement speed of the pull rod 12 will also slow down. The way the charging pile body 1 falls will become a slow descent, so that it will not suddenly fall and cause impact to the charging pile body 1, and there will be no accident of sudden pinching and injuring people. When the pull rod 12 passes through the locking tongue 14 during the reset process, it will squeeze the bevel of the locking tongue 14, and eventually squeeze the locking tongue 14 into the outer shell 13, so that the pull rod 12 can return to its original position through the locking tongue 14.

[0041] After operation: The charging pile body 1 remains underground, with the cover plate 10 preventing direct sunlight exposure.

[0042] Example 2:

[0043] Unlike Embodiment 1, when there is insufficient space to install the two long strip baffles 27 in a confined area, the two baffles 27 are replaced with PVC plastic baffles. The width is the same as the width of the slide groove 11, and the thickness is 3.5mm. The two plastic baffles 27 are flexible and bendable. The two plastic baffles 27 are fixed to both ends of the slide groove 11, and then the two baffles 27 are fixed to the pull rod 12 with clamps or adhesives. The side walls of the two baffles 27 can be covered with wear-resistant rubber, and the two baffles 27 can move up and down in the slide groove.

[0044] When the lever 12 moves along the slide rail 3 11, the baffle 27 on one side of the moving direction will bend downward under the action of gravity and compression, while the plastic baffle 27 on the other side will be continuously straightened, and finally the lever 12 will be completely straightened when it moves to the limit position. Compared to the baffle 27 in Embodiment 1, the baffle 27 in Embodiment 2 is easier to install, occupies less space, and has a lower cost per use. However, because it needs to move up and down inside the slide groove 3 11, its dust-blocking effect is not as good as the whole baffle 27 used in Embodiment 1. Furthermore, the whole baffle 27 moves inside a separate slide groove 4 26, which intersects perpendicularly with the slide groove 3 11, making it more difficult for dust to enter the slide groove 3 11. The plastic baffle 27 may age faster due to sun and rain exposure, and its wear may accelerate during up and down movement. Once a certain gap is formed due to wear, dust can more easily enter the slide groove 3 11. Compared to the metal baffle 27 in Embodiment 1, it requires more frequent maintenance and timely replacement when problems are found.

[0045] The functions and implementation processes not described in this embodiment are the same as in Embodiment 1, so they will not be elaborated further.

[0046] The above two embodiments are merely illustrative examples among the many embodiments of the present invention. Various variations can be made without departing from the principles of the present invention. Embodiments created by those skilled in the art through modifications to the present invention without creative effort are also within the scope of protection of the present invention.
