Description

Technical Field

[0001] This utility model belongs to the field of automobile charging pile technology, specifically relating to a retractable underground charging pile for new energy vehicles. Background Technology

[0002] A new energy vehicle charging pile is a device that replenishes the power of electric vehicles. An underground new energy vehicle charging pile is one where the main body of the charging equipment is buried underground. This design allows the charging pile to occupy almost no ground space when not in use and to better integrate with the surrounding environment. Its underground protective shell typically has waterproof, moisture-proof, and dustproof functions, effectively protecting internal electrical components and extending the equipment's lifespan. However, because the underground part of an underground charging pile is surrounded by soil, and soil has relatively poor thermal conductivity, the heat generated during charging is difficult to dissipate quickly through the air like with surface charging piles. When the charging equipment operates for a long time, heat accumulates underground, causing the internal temperature of the equipment to rise. This is especially true in hot summer weather when the ground temperature is high, and the underground heat cannot be effectively dissipated, leading to excessively high internal temperatures and affecting the performance and lifespan of the charging equipment.

A movable pipe is movably connected to the outer side of the connecting pipe. A floating plate is provided on the outer side of the movable pipe. Several support bars are provided on the top of the movable pipe. A stop block is provided on the top of the support bars.

[0005] The underground box has several support seats at the bottom of its inner cavity, and a limiting block at the top of each support seat. The ruler is slidably connected to the inner side of the limiting block.

[0006] The top of the protective shell is fixedly connected to the bottom of the extension plate, and the bottom of the protective shell is fixedly connected to the outside of the underground box.

[0007] The charging pile is equipped with a top cover, the size of which is larger than the inner dimensions of the underground box.

[0022] This implementation plan includes an underground enclosure 1, a drive motor 111, and a charging pile 2. The underground enclosure 1 is the shell part buried underground, and the charging pile 2 can charge the vehicle. The charging pile 2 is slidably connected to the inside of the underground enclosure 1. The height of the charging pile 2 can be adjusted by sliding it up and down inside the underground enclosure 1. Fixing plates 21 are provided on both sides of the charging pile 2, and the fixing plates 21 are fixedly connected to the charging pile 2. The two fixing plates 21 are symmetrical. A connecting groove 211 is provided on the inner side of the fixing plate 211. The bottom of the connecting groove 211 is open. An internally threaded pipe 212 is fixedly connected to the inner side of the connecting groove 211. The internally threaded pipe 212 has threads on its inner side and is located at the bottom of the fixing plate 21. The inner side of the charging pile 2 is provided with a threaded rod 3, which is threadedly connected to the internal threaded tube 212. When the threaded rod 3 rotates, the charging pile 2 can slide up and down. The bottom of the threaded rod 3 is provided with a gear 31, which is fixedly connected to the threaded rod 3. The gear 31 and the threaded rod 3 will rotate synchronously. The outer side of the two gears 31 is provided with a ruler 32, and the two gears 31 are located on the inner side of the ruler 32. The ruler 32 is meshed with the gears 31. When one of the gears 31 rotates, the two gears 31 will rotate synchronously through the transmission of the ruler 32, thereby driving the two threaded rods 3 to rotate synchronously. The bottom of the inner cavity of the underground box 1 is provided with a hollow frame 11 and a fixed seat 12. Both the hollow frame 11 and the fixed seat 12 are fixedly connected to the underground box 1. The two gears 31 are respectively connected to the hollow frame 11 and the fixed seat 12. The hollow frame 11 and the fixed base 12 are rotatably connected. The hollow frame 11 and the fixed base 12 are at the same height. Therefore, the two gears 31 are at the same height. The drive motor 111 is located inside the hollow frame 11. The top of the drive motor 111 passes through the hollow frame 11 and is connected to the gears 31. The drive motor 111 can control the rotation of the gears 31, which is beneficial for driving the two threaded rods 3 to rotate. Both sides of the underground box 1 are provided with extension plates 13. The extension plates 13 are fixedly connected to the underground box 1 and are horizontal. Both sides of the underground box 1 are provided with protective shells 4. The protective shells 4 are fixedly connected to the underground box 1 and there is a space between the protective shells 4 and the underground box 1. The inner side of the protective shells 4 is provided with connecting pipes 41. The connecting pipes 41 are located between the protective shells 4 and the underground box 1. The connecting pipe 41 has two ends that pass through the underground box 1 and the extension plate 13, respectively. One end of the connecting pipe 41 is located at the top of the extension plate 13, and the other end is connected to the underground box 1. A movable pipe 42 is movably connected to the outside of the connecting pipe 41. The movable pipe 42 is in a vertical state. By sliding the movable pipe 42 outside the connecting pipe 41, the distance between the top of the movable pipe 42 and the ground can be adjusted. A float plate 421 is provided on the outside of the movable pipe 42. The float plate 421 is fixedly connected to the movable pipe 42 and has buoyancy. If there is water on the ground, the buoyancy of the float plate 421 will cause the movable pipe 42 to rise with the rise of the water level, thereby ensuring that the top of the movable pipe 42 is always at a certain distance from the water surface and preventing water from entering the inside of the connecting pipe 41 and the movable pipe 42.The top of the movable pipe 42 is provided with several support bars 422. The support bars 422 are vertical and fixedly connected to the movable pipe 42. The top of the support bars 422 is provided with a stop block 43, which is fixedly connected to several other stop blocks 43. The stop blocks 43 can shield the top of the movable pipe 42 to prevent rainwater from entering the movable pipe 42. When wind passes between the movable pipe 42 and the stop blocks 43, it can carry the air inside the connecting pipe 41 outward. Since the two movable pipes 42 are positioned opposite each other, when air is drawn out of one connecting pipe 41, the other connecting pipe 41 will draw outside air into the underground box 1, thereby exchanging the air inside the underground box 1 with the outside air and achieving the purpose of heat dissipation inside the underground box 1.

[0023] The bottom of the inner cavity of the underground box 1 is provided with several support seats 14, and the top of the support seat 14 is provided with a limiting block 141. The ruler 32 is slidably connected to the inner side of the limiting block 141. The limiting block 141 can limit the ruler 32 to ensure that the ruler 32 is in a horizontal state.

[0024] The top of the protective shell 4 is fixedly connected to the bottom of the extension plate 13, and the bottom of the protective shell 4 is fixedly connected to the outside of the underground box 1; there is a space between the protective shell 4 and the underground box 1, and the connecting pipe 41 is located in the space between the protective shell 4 and the underground box 1.

[0025] The top of the charging pile 2 is provided with a top cover 22, the size of which is larger than the inner size of the underground box 1. The top cover 22 can cover the gap between the underground box 1 and the charging pile 2 to prevent rainwater from seeping into the underground box 1.

[0026] A limiting plate 33 is provided at the end of the threaded rod 3 away from the gear 31. The size of the limiting plate 33 is larger than that of the internal threaded tube 212. The limiting plate 33 can prevent the charging pile 2 from separating from the threaded rod 3 due to excessive rising distance.

[0027] The movable tube 42 passes through the extension plate 13, and the size of the float plate 421 is larger than the movable tube 42. The float plate 421 can prevent the float plate 421 from falling below the extension plate 13, ensuring that the float plate 421 is always located at the top of the extension plate 13.

[0028] The hollow frame 11 and the fixed seat 12 are positioned opposite each other, and several support seats 14 are located between the hollow frame 11 and the fixed seat 12; the positions of the two threaded rods 3 are also corresponding, and the support seats 14 can support the ruler 32 so that the ruler 32 and the gear 31 are at the same height.

[0029] The working principle and usage process of this utility model are as follows: During use, the charging pile 2 can charge a car. The drive motor 111 rotates the top gear 31 and threaded rod 3. Through the transmission of the belt 32, the two gears 31 and the two threaded rods 3 rotate synchronously. Since the threaded rod 3 is threadedly connected to the internal threaded tube 212, when the two threaded rods 3 rotate simultaneously, they can drive the charging pile 2 to move up and down. When air passes between the movable tube 42 and the stop block 43, it can carry the air inside the connecting tube 41 outwards. Because the two movable tubes... The positions of 42 correspond to each other. Therefore, when air is drawn out of one of the connecting pipes 41, the other connecting pipe 41 will draw outside air into the underground box 1, thereby exchanging the air inside the underground box 1 with the outside air, achieving the purpose of heat dissipation inside the underground box 1. In addition, the float plate 421 has buoyancy. If there is water on the ground, the buoyancy of the float plate 421 will cause the movable pipe 42 to rise with the rise of the water level, thereby ensuring that the top of the movable pipe 42 is always a certain distance from the water surface, preventing water from entering the inside of the connecting pipe 41 and the movable pipe 42.
