[0016] The beneficial effects of the present invention are:

[0017] (1) The underground new energy vehicle charging pile described in the present invention can bury the placement slot underground when in use. Since the charging pile body is located inside the placement slot, it can avoid the charging pile body being exposed to the external environment for a long time, thereby reducing the probability of damage to the charging pile body. When it is necessary to charge the new energy vehicle, the charging pile body can be lifted by the lifting structure, so that the charging pile body moves from the inside of the placement slot to the outside of the placement slot. At this time, the new energy vehicle can be charged through the charging pile body.

When a heavy object is located at the top of the shielding structure, the shielding structure can drive the locking structure to move under the action of the gravity of the heavy object. When the locking structure moves, the lifting structure cannot drive the charging pile body to move. Therefore, it can prevent the shielding structure from overturning a person or a car during the movement, and at the same time prevent the power components inside the lifting structure from being subjected to a large load, thereby effectively improving the safety and stability of use.

[0018] (2) The underground new energy vehicle charging pile described in the present invention can offset part of the gravity of the charging pile body through the counterweight structure when the lifting structure drives the charging pile body to move, thereby saving energy and labor. At the same time, when the charging pile body is damaged, it can be quickly separated from the lifting structure through the fixed structure, thereby realizing the rapid disassembly of the charging pile body and facilitating the inspection and maintenance of the charging pile body.

[0019] (3) In the underground new energy vehicle charging pile described in the present invention, excess wires can be wound and stored through the winding structure during use, thereby preventing excess wires from being entangled around the charging pile body and preventing excess wires from having a bad influence on the lifting and lowering of the charging pile body, thereby making it more convenient to use.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, achieved purposes and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 10 As shown in

[0035] As Figure 1 , Figure 10 and Figure 11As shown in the figure, the winding structure 8 includes a connecting column 801 and a sliding sleeve 802. The connecting column 801 is fixedly connected to the charging pile body 9. The outer part of the connecting column 801 is slidably connected with the sliding sleeve 802. Two baffles 803 are fixedly connected to the sliding sleeve 802. A pressing sleeve 804 is slidably connected to the sliding sleeve 802. Four pushing blocks 805 are fixedly connected to the pressing sleeve 804. Two limiting blocks 806 are slidably connected to the connecting column 801. One ends of the two limiting blocks 806 are respectively in contact with two of the pushing blocks 805. A fourth spring 807 is in contact between the two limiting blocks 806. The baffle 803 is perpendicular to the sliding sleeve 802. One end of the pressing sleeve 804 extends to the outside of the sliding sleeve 802. The cross-section of the pushing block 805 is trapezoidal. One end of the cross-section of the limiting block 806 is trapezoidal. That is, during use, the excess wires can be wound around the sliding sleeve 802. The wound wires can be blocked by the two baffles 803, so that the wound wires can be prevented from falling off the sliding sleeve 802, thus effectively improving the stability of use. By winding the excess wires around the sliding sleeve 802, the excess wires can be prevented from coiling around the periphery of the charging pile body 9, thus avoiding adverse effects on the lifting of the charging pile body 9. When it is necessary to use the charging plug to charge a new energy vehicle, first move the charging pile body 9 from the inside of the placement groove 1 to the outside of the placement groove 1. Then, by pressing the pressing sleeve 804, the movement of the pressing sleeve 804 drives the movement of the four pushing blocks 805. The movement of two of the pushing blocks 805 will respectively contact the movement of the two limiting blocks 806, and the fourth spring 807 contracts. When one side of the pushing block 805 is in contact with the sliding sleeve 802 and cannot continue to push the pressing sleeve 804, the sliding sleeve 802 can be pulled at this time. During the movement of the sliding sleeve 802, it will contact the limiting block 806 and continue to move towards the inside of the connecting column 801. When pulling the sliding sleeve 802, release the pressing sleeve 804 and then continue to pull the sliding sleeve 802. Next, during the process of pulling the sliding sleeve 802, under the action of the fourth spring 807, the two limiting blocks 806 will be engaged with the sliding sleeve 802 again, so that the sliding sleeve 802 cannot continue to move. At this time, since the sliding sleeve 802 moves from the inside of the charging pile body 9 to the outside of the charging pile body 9, the charging pile body 9 will not block the wires wound around the sliding sleeve 802. Therefore, it is more convenient to take the wires and also convenient to wind the wires, thus effectively improving the operation convenience.

[0036] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9As shown, the lifting structure 2 includes a sliding seat 201 and a motor 202. Two sliding seats 201 are fixedly connected inside the placement groove 1. The same placement table 206 is slidably connected between the two sliding seats 201. A motor 202 is installed at the bottom end of the sliding seat 201. A lead screw 203 is rotatably connected to the sliding seat 201. The bottom end of the lead screw 203 is fixedly connected to the output shaft of the motor 202. An adapter sleeve 204 is threadedly connected to the lead screw 203. The adapter sleeve 204 is rotatably connected to the placement table 206. A charging pile body 9 is placed on the top end of the placement table 206. A clamping structure 3 is provided on the sliding seat 201. A plurality of card slots 205 are provided on the adapter sleeve 204. A groove 207 is provided at the top end of the placement table 206. The top end of the groove 207 is in a flared structure. The bottom end of the charging pile body 9 is located inside the groove 207. The plurality of card slots 205 are distributed in a circumferential array about the rotation center of the adapter sleeve 204. The width of both ends of the cross section of the adapter sleeve 204 is smaller than the width of the middle. The clamping structure 3 includes a pressing ring 301 and a resisting block 302. Two pressing rings 301 are slidably connected to the placement table 206. Two resisting blocks 302 are fixedly connected to the bottom end of the pressing ring 301. The resisting blocks 302 are slidably connected to the placement table 206. A clamping block 303 is abutted against the bottom end of the resisting block 302. The clamping block 303 is slidably connected to the placement table 206. One ends of the two clamping blocks 303 are respectively engaged with two of the card slots 205. A first spring 304 is abutted between the clamping block 303 and the placement table 206. The bottom end of the cross section of the resisting block 302 is in a trapezoidal structure. One end of the cross section of the clamping block 303 is in a trapezoidal structure. The top end of the pressing ring 301 extends to the outside of the placement table 206. The shielding structure 4 includes a sleeve rod 401 and a sliding column 402. Four sleeve rods 401 are fixedly connected to the placement table 206. A sliding column 402 is slidably connected inside the sleeve rod 401. The top ends of the four sliding columns 402 are fixedly connected to the same shielding cover 404. A second spring 405 is sleeved on the outside of the sliding column 402. One end of the second spring 405 abuts against the shielding cover 404 and the other end abuts against the sleeve rod 401. A pressing rod 403 is fixedly connected to the sliding column 402. That is, when in use, the placement groove 1 can be buried underground. Since the charging pile body 9 is located inside the placement groove 1, the charging pile body 9 can be prevented from being exposed to the external environment for a long time, thereby reducing the probability of damage to the charging pile body 9. When it is necessary to charge a new energy vehicle, two motors 202 can be started simultaneously. The output shaft of the motor 202 rotates to drive the lead screw 203 to rotate. Since the ends of the two clamping blocks 303 are engaged with two of the card slots 205 at this time, the adapter sleeve 204 and the placement table 206 cannot rotate relative to each other. At this time, when the lead screw 203 rotates, it will drive the adapter sleeve 204 to move in the axial direction of the lead screw 203. The simultaneous movement of the two adapter sleeves 204 will drive the placement table 206 to move.By setting two sliding seats 201, it plays a role in guiding the movement of the placement table 206. The movement of the placement table 206 will drive the movement of the charging pile body 9, so that the charging pile body 9 moves from the inside of the placement groove 1 to the outside of the placement groove 1. At this time, the new energy vehicle can be charged through the charging pile body 9. The rain shield 404 and the water retaining frame 7 can prevent rainwater from entering the inside of the placement groove 1. And when there is a heavy object on the top of the rain shield 404, the rain shield 404 will move under the action of the gravity of the heavy object. The movement of the rain shield 404 drives the four sliding columns 402 to slide inside the four sleeve rods 401 respectively, and the four second springs 405 contract. The movement of the sliding column 402 drives the movement of the pressure lever 403, and the movement of the pressure lever 403 will push against the movement of the pressure ring 301. The movement of the pressure ring 301 drives the movement of the abutting block 302, and the movement of the abutting block 302 will push against the movement of the clamping block 303 away from the clamping groove 205, and the first spring 304 contracts. When the bottom end of the rain shield 404 abuts against the top end of the placement groove 1, it will stop moving. At this time, the end of the clamping block 303 is not engaged with the clamping groove 205. Therefore, when the lead screw 203 rotates, it will drive the connecting sleeve 204 to rotate, and will not change the position of the placement table 206. Therefore, it can prevent the rain shield 404 from tipping over people or cars during the movement, and at the same time avoid the motor 202 from bearing a large load and avoid damage to the motor 202, thus effectively improving the safety and stability of use.,

[0037] Specifically, Figure 1 、 Figure 5 、 Figure 6 and Figure 7As shown, the fixing structure 6 includes a clamping plate 601 and a sliding plate 603. Two sliding plates 603 are slidably connected to the placing table 206. A clamping plate 601 is fixedly connected to the sliding plate 603. The end parts of the two clamping plates 601 are respectively clamped between the two sides of the charging pile body 9. A rotating block 602 is rotatably connected to one of the clamping plates 601. A rack 604 is fixedly connected to the sliding plate 603. A gear 605 is rotatably connected to the bottom end of the placing table 206. The two sides of the gear 605 are respectively meshed with the two racks 604. A third spring 606 is fixedly connected between the sliding plate 603 and the placing table 206. The counterweight structure 5 includes a connecting block 501 and a guide wheel 502. Four connecting blocks 501 are fixedly connected to the placing groove 1. A guide wheel 502 is rotatably connected to the connecting block 501. A connecting rope 503 is wound around the guide wheel 502. One end of the connecting rope 503 is fixedly connected to the placing table 206. The other end of the connecting rope 503 is fixedly connected to the counterweight block 504. A guide post 505 is fixedly connected to the connecting block 501. The counterweight block 504 is slidably connected to the guide post 505. That is, during the movement of the placing table 206, the counterweight block 504 will slide on the guide post 505. Since the counterweight block 504 and the placing table 206 are connected by the connecting rope 503 and the connecting rope 503 is wound around the guide wheel 502, the gravity of the counterweight block 504 can be converted into an upward pulling force on the placing table 206, so that a part of the gravity of the charging pile body 9 can be offset by the gravity of the counterweight block 504, thus playing a role in energy saving and labor saving. At the same time, when the charging pile body 9 is damaged and needs to be disassembled and repaired, the charging pile body 9 can be first moved from the inside of the placing groove 1 to the outside of the placing groove 1, and then by pulling one of the clamping plates 601, the movement of one of the clamping plates 601 will drive the movement of one of the sliding plates 603. Since racks 604 are fixedly connected to both sliding plates 603 and the racks 604 are meshed with the two sides of the gear 605, when one of the sliding plates 603 moves, it will drive the other sliding plate 603 to move in the opposite direction, so that the other clamping plate 601 also moves in the opposite direction, so that the two clamping plates 601 move away from the charging pile body 9 at the same time. When the end parts of the two clamping plates 601 are no longer clamped with the charging pile body 9, the rotating block 602 can be rotated by ninety degrees. At this time, when the clamping plate 601 is released, the third spring 606 will not extend under the support of the rotating block 602 to make the clamping plate 601 be clamped with the charging pile body 9 again, so that it is possible to avoid having to keep pulling the clamping plate 601 by hand during the disassembly process, thus effectively improving the operation convenience. Next, the charging pile body 9 can be removed from the placing table 206, and at this time, the rapid disassembly of the charging pile body 9 is completed, thus facilitating the inspection and maintenance of the charging pile body 9.

[0038] When the present invention is in use, the placement slot 1 can be buried underground. Since the charging pile body 9 is located inside the placement slot 1, the charging pile body 9 can be prevented from being exposed to the external environment for a long time, thereby reducing the probability of damage to the charging pile body 9. When it is necessary to charge the new energy vehicle, the two motors 202 can be started at the same time. The output shaft of the motor 202 rotates to drive the screw rod 203 to rotate. Since the ends of the two clamping blocks 303 are engaged with two of the clamping slots 205 at this time, the connection sleeve 204 and the placement platform 206 cannot rotate. At this time, the rotation of the screw rod 203 will drive the connection sleeve 204 to move in the axial direction of the screw rod 203. , the simultaneous movement of the two connecting sleeves 204 will drive the placement table 206 to move. The two slide seats 201 are provided to guide the movement of the placement table 206. During the movement of the placement table 206, the counterweight 504 will slide on the guide column 505. Since the counterweight 504 and the placement table 206 are connected by a connecting rope 503, and the connecting rope 503 is wound around the guide wheel 502, the gravity of the counterweight 504 can be converted into an upward pulling force on the placement table 206, so that the gravity of a part of the charging pile body 9 can be offset by the gravity of the counterweight 504, thereby achieving energy saving and labor saving. The movement of the placement table 206 will The charging pile body 9 will be driven to move, so that the charging pile body 9 moves from the inside of the placement groove 1 to the outside of the placement groove 1. At this time, the new energy vehicle can be charged through the charging pile body 9. The shielding cover 404 and the water retaining frame 7 can prevent rainwater from entering the inside of the placement groove 1. When a heavy object is located at the top of the shielding cover 404, the shielding cover 404 will move under the action of the gravity of the heavy object. The movement of the shielding cover 404 drives the four sliding columns 402 to slide inside the four sleeve rods 401 respectively, and the four second springs 405 contract. The movement of the sliding column 402 will drive the pressure rod 403 to move, and the movement of the pressure rod 403 will resist the movement of the pressure ring 301. The pressure ring 301 moves The movement of the stopper 302 will cause the stopper 303 to move away from the slot 205, and the first spring 304 will contract. When the bottom end of the shielding cover 404 contacts the top end of the placement slot 1, the movement will stop. At this time, the end of the block 303 is not engaged with the slot 205. Therefore, when the screw rod 203 rotates, the connection sleeve 204 will be driven to rotate without changing the position of the placement platform 206. Therefore, the shielding cover 404 can be prevented from overturning a person or a car during the movement, and the motor 202 can be prevented from being subjected to a large load, thereby preventing the motor 202 from being damaged, thereby effectively improving the safety and stability of use.

[0039] During the use process, the redundant wires can be wound around the sliding sleeve 802, and the wound wires can be blocked by the two baffles 803, so as to prevent the wound wires from falling off the sliding sleeve 802, effectively improving the stability of use. By winding the redundant wires around the sliding sleeve 802, the redundant wires can be prevented from coiling around the periphery of the charging pile body 9, thus avoiding adverse effects on the lifting of the charging pile body 9. When it is necessary to use the charging plug to charge a new energy vehicle, first move the charging pile body 9 from the inside of the placement groove 1 to the outside of the placement groove 1, and then press the pressing sleeve 804. The movement of the pressing sleeve 804 drives the movement of the four push blocks 805. Two of the push blocks 805 will respectively contact and move two limit blocks 806, and the fourth spring 807 contracts. When one side of the push block 805 contacts the sliding sleeve 802 and cannot continue to push the pressing sleeve 804, the sliding sleeve 802 can be pulled at this time. During the movement of the sliding sleeve 802, it will contact the limit block 806 and continue to move towards the inside of the connecting column 801. When pulling the sliding sleeve 802, release the pressing sleeve 804 and then continue to pull the sliding sleeve 802. Next, during the process of pulling the sliding sleeve 802, under the action of the fourth spring 807, the two limit blocks 806 will be engaged with the sliding sleeve 802 again, so that the sliding sleeve 802 cannot continue to move. At this time, since the sliding sleeve 802 moves from the inside of the charging pile body 9 to the outside of the charging pile body 9, the charging pile body 9 will not block the wires wound around the sliding sleeve 802, so it is more convenient to take the wires and also convenient to wind the wires, effectively improving the operation convenience;

[0040] When the charging pile body 9 is damaged and needs to be disassembled and repaired, the charging pile body 9 can be first moved from the inside of the placement groove 1 to the outside of the placement groove 1, and then by pulling one of the clamping plates 601, the movement of one of the clamping plates 601 will drive the movement of one of the sliding plates 603. Since racks 604 are fixedly connected to both sliding plates 603 and the racks 604 are engaged with both sides of the gear 605, when one of the sliding plates 603 moves, it will drive the other sliding plate 603 to move in the opposite direction, so that the other clamping plate 601 also moves in the opposite direction, so that the two clamping plates 601 move away from the charging pile body 9 at the same time. When the ends of the two clamping plates 601 are no longer engaged with the charging pile body 9, the rotating block 602 can be rotated by 90 degrees. At this time, when the clamping plate 601 is released, the third spring 606 will not extend under the support of the rotating block 602 and the clamping plate 601 will be engaged with the charging pile body 9 again, so as to avoid the need to keep pulling the clamping plate 601 by hand during the disassembly process, effectively improving the operation convenience. Next, the charging pile body 9 can be removed from the placement table 206, and at this time, the rapid disassembly of the charging pile body 9 is completed, facilitating the maintenance and repair of the charging pile body 9.

[0041] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
