[0002] At present, when using charging piles to charge new energy vehicles, since the charging time of new energy vehicles is relatively long, the electrical components in the charging piles need to run for a long time, which makes the heat generated by the electrical components easily accumulate inside the charging pile, causing the temperature of the charging pile to be too high, resulting in damage to some electrical components. Therefore, the charging piles generally have a heat dissipation function.
[0003] A common heat dissipation charging pile is designed in the related technology, which includes a pile body, a side wall of the pile body is provided with a heat dissipation port connecting the inside and outside of the pile body, a filter is fixedly provided in the heat dissipation port, and a heat exhaust fan is installed in the pile body, and the heat exhaust fan is directly opposite to the heat dissipation port; when the charging pile is used to charge a new energy vehicle, the heat exhaust fan is started to discharge the hot air in the pile body from the heat dissipation port, thereby achieving the effect of lowering the internal temperature of the pile body, and the filter prevents external dust from entering the pile body.
[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: for charging piles that need to be installed outdoors, there is a lot of dust in the outdoor air, and the dust easily sticks to the filter in large quantities. In addition, it sometimes rains outdoors, and the rain combined with the dust on the filter will make the dust moist, increase the stickiness of the dust, and further aggravate the blockage of the filter, affecting the heat dissipation effect. Summary of the invention
[0005] In order to reduce the dust on the filter, prevent rainwater from coming into contact with the dust on the filter and aggravating the clogging of the filter, and ensure the heat dissipation effect of the charging pile, the present application provides a new energy heat dissipation charging pile.
[0006] The new energy heat dissipation charging pile provided in this application adopts the following technical solution: A new energy heat dissipation charging pile comprises a pile body, wherein two opposite side walls of the pile body are respectively provided with a vent, a mounting frame is fixedly arranged in the vent, a filter is fixedly arranged at one end of the mounting frame facing the inside of the pile body, a plurality of blades are arranged at one end of the mounting frame facing the outside of the pile body, the blades are evenly distributed in the height direction of the pile body, the ends of the blades are rotatably matched with the side walls of the mounting frame, and the adjacent blades can fit each other, a switch assembly is also arranged in the pile body, and the switch assembly is used to drive all the blades to rotate synchronously; storage bodies extending toward the inside of the pile body are integrally formed on the opposite side walls of the pile body, a storage groove extending into the storage body is arranged on the side walls of the pile body, the storage groove is located above the vent, a rain shield is arranged in the storage groove, and the rain shield can extend out of or retract into the storage groove.
[0007] By adopting the above technical solution, when the charging pile is not working, the switch assembly drives all the blades to rotate so that the adjacent blades fit together, the vent is closed, and dust and rainwater cannot enter. When the charging pile is working on a non-rainy day, the switch assembly drives all the blades to rotate so that the adjacent blades move away from each other, and the vent is opened, one of which is used for air intake and the other is used for air outlet, so that the heat in the charging pile can be fully dissipated. When the charging pile is working on a rainy day, the rain shield is driven to extend from the storage slot, which can prevent rainwater from passing over the open blades and contacting the filter, thereby reducing the dust on the filter, and trying to prevent rainwater from contacting the dust on the filter and clogging the filter, thereby ensuring the heat dissipation effect of the charging pile.
[0008] Preferably, the rain shield includes a slide and a waterproof cloth. The slide slides with the storage slot in a direction approaching or moving away from the storage slot, and the slide can be extended or retracted into the storage slot. One end of the waterproof cloth is fixedly connected to an end of the slide away from the pile body, and the other end of the waterproof cloth is fixedly connected to an end of the storage slot facing the outside of the pile body.
[0009] By adopting the above technical solution, when it is necessary to extend the rain shield, the slide is driven to slide outward in the storage slot, driving the waterproof cloth to unfold, thereby preventing rain from entering the vent. When it is not necessary to shield the rain, the slide is driven to slide into the storage slot, and the waterproof cloth is retracted into the storage slot, preventing the discharged rain from accumulating outside the vent and being difficult to disperse, thereby reducing the impact on the normal ventilation and heat dissipation of the charging pile.
[0010] Preferably, a storage gap for storing a waterproof cloth is reserved between the top of the slide and the storage groove, and the waterproof cloth is fixed to the top of the slide by glue in the middle of the sliding direction of the slide.
[0011] By adopting the above technical solution, the waterproof cloth is glued to the top of the slide in the middle of the sliding direction of the slide. When the slide retracts inwardly into the storage groove, the slide pulls the middle of the waterproof cloth into the storage groove first, so that the waterproof cloth is stably folded in the storage groove. The waterproof cloth can be neatly stored in the storage gap, which improves the service life of the waterproof cloth and allows the water-blocking side of the waterproof cloth to be away from the bottom of the storage groove.
[0012] Preferably, a push-out spring is provided in the storage slot, one end of the push-out spring abuts against the end wall of the storage slot, and the other end of the push-out spring abuts against one end of the slide toward the storage slot, and the push-out spring drives the slide to slide away from the storage slot.
[0013] By adopting the above technical solution, when the rain shield needs to be used, the push-out spring provides thrust to make the slide frame slide outward and provide support for the slide frame to extend out of the storage slot, thereby ensuring the unfolded state of the waterproof cloth and effectively blocking rainwater in time. When the rain shield is not needed, the push-out spring is in a compressed state to prepare for the next automatic extension.
[0014] Preferably, the switch assembly includes a rack and a gear, the rotating shaft of the blade passes through the side wall of the mounting frame and is coaxially connected to the gear, the rack slides vertically on the side wall of the mounting frame, and the rack simultaneously meshes with the gears on all blades.
[0015] By adopting the above technical solution, when the rack slides vertically, since the rack meshes with the gears on all the blades at the same time, the movement of the rack will drive all the gears to rotate synchronously, thereby realizing the synchronous opening and closing of all the blades and the rapid opening and closing of the vent.
[0016] Preferably, the switch assembly also includes a reset component and a tension spring, one end of the tension spring is connected to the bottom of the pile body, and the other end of the tension spring is connected to the bottom of the rack, the tension spring drives the rack close to the bottom of the inner wall of the pile body to drive adjacent blades to rotate away from each other; the reset component is used to drive the rack away from the bottom of the pile body to drive adjacent blades to rotate until they are in contact with each other.
[0017] By adopting the above technical solution, when the vent needs to be opened for heat dissipation, the reset component does not work, and the tension spring pulls the rack close to the bottom of the inner wall of the pile body, driving the gear to rotate, so that the adjacent blades are separated from each other. When the vent needs to be closed, the reset component drives the rack away from the bottom of the inner wall of the pile body, driving the gear to rotate in the opposite direction, so that the adjacent blades fit together, realizing the switching of the blade state.
[0018] Preferably, the reset component includes a tension rope, a sliding platform, a roller, and a driving component. The sliding platform slides in the pile body, and the driving component is used to drive the sliding platform to slide and lock the sliding platform. The roller is rotatably arranged on the side wall of the sliding platform. One end of the tension rope extends into the storage groove and is fixedly connected to the end of the slide toward the storage groove. The other end of the tension rope is fixedly connected to the top of the rack. The middle part of the tension rope is sleeved on the roller, and the elastic force of the tension spring is greater than the elastic force of the ejection spring.
[0019] By adopting the above technical solution, when the charging pile is not working, the driving member drives the sliding platform to slide, the tension rope is pulled by the roller, and both ends of the tension rope are tightened at the same time. One end of the tension rope drives the rack to overcome the elastic force of the tension spring and slide upward, and the blades are closed. The other end of the tension rope drives the slide to overcome the elastic force of the push-out spring, so that the slide retracts back to the storage slot. When the charging pile is working on a non-rainy day, the driving member drives the sliding platform to slide in the opposite direction slightly. Since the elastic force of the tension spring is greater than the elastic force of the push-out spring, the tension spring acts before the push-out spring and pulls down the rack, and the blades open. When the charging pile is working on a rainy day, the driving member drives the sliding platform to slide in the opposite direction significantly. The slide quickly extends out of the storage slot under the action of the push-out spring, and the waterproof cloth is unfolded to keep out the rain. At the same time, the rack must be pulled down by the tension spring, and the blades open to dissipate heat, so that the normal heat dissipation of the charging pile can be ensured even on rainy days and rainwater is prevented from contacting the filter. In this way, only one power source is needed to realize the control of three working states of the charging pile: not working, working on non-rainy days, and working on rainy days. There are fewer power parts, low maintenance costs, and less heat.
[0020] Preferably, the sliding platform is arranged to slide in the vertical direction within the pile body, and there are two symmetrical rollers on the side wall of the sliding platform. One tension rope is respectively mounted on the two rollers, and one tension rope is connected to the slide and rack on one side of the pile body, and the other tension rope is connected to the slide and rack on the other side of the pile body.
[0021] By adopting the above technical solution, the sliding platform slides in the vertical direction, and with the two symmetrically arranged rollers and two tension ropes, the two slides and two racks on the opposite sides of the pile body can be controlled simultaneously to ensure the synchronization and coordination of the traction actions of the two tension ropes.
[0022] Preferably, the driving member comprises a servo motor and a screw rod, wherein the screw rod is vertical and rotates in the pile body, the screw rod is threadedly engaged with the sliding platform, the servo motor is fixedly arranged on the inner wall of the pile body, and the driving shaft of the servo motor is coaxially connected to the screw rod.
[0023] By adopting the above technical solution, the servo motor can accurately control the speed and direction of the drive shaft, thereby accurately driving the lead screw to rotate. The lead screw engages with the thread of the slide table, converting the rotational motion of the lead screw into the linear motion of the slide table, thereby achieving precise control of the position of the slide table.
[0024] Preferably, a raindrop sensor is fixedly arranged on the top of the pile body, and the raindrop sensor is electrically connected to the servo motor.
[0025] By adopting the above technical solution, the raindrop sensor can detect in real time whether it is raining outside. During the operation of the charging pile, once the raindrop sensor detects rain, the raindrop sensor sends a signal to the servo motor, and the servo motor drives the sliding platform to slide significantly according to the preset program to extend the rain shield, thereby realizing the automatic response of the charging pile to weather changes and improving the intelligence and adaptability of the charging pile.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting rotatable blades and retractable rain shields, the opening and closing of the vents and rain protection are controlled under different working conditions, which reduces the accumulation of dust on the filter and prevents the combination of rain and dust from aggravating the clogging of the filter, thus ensuring the heat dissipation effect of the charging pile; 2. By setting up a sliding platform, rollers, tension ropes, slides, driving parts, gears, racks, push-out springs, and tension springs, only one power source can be used to control the charging pile in three working states: not working, working on non-rainy days, and working on rainy days, which reduces costs and reduces the heat generation of the power source; 3. By setting up raindrop sensors and servo motors, the charging pile can automatically sense and respond to weather changes, improving the intelligence and adaptability of the charging pile.

[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The present application embodiment discloses a new energy heat dissipation charging pile. Figure 1 and Figure 2 , which comprises a pile body 1, and a vent 11 is provided on each of the two opposite side walls of the pile body 1. A mounting frame 2 is fixedly provided in the vent 11, and a filter 21 is fixedly provided at one end of the mounting frame 2 facing the inside of the pile body 1. A plurality of blades 22 are provided at one end of the mounting frame 2 facing the outside of the pile body 1, and the blades 22 are evenly distributed in the height direction of the pile body 1. The ends of the blades 22 are rotated with the side walls of the mounting frame 2, and adjacent blades 22 can fit each other. A fan 23 is also provided in the mounting frame 2 on any side wall of the pile body 1, and the fan 23 guides the airflow to enter or leave the pile body 1. A switch assembly 4 is also provided in the pile body 1, and the switch assembly 4 is used to drive all the blades 22 to rotate synchronously. When the charging pile starts working, the switch assembly 4 drives the blades 22 to rotate synchronously, and all the blades 22 move away from each other, and the low-temperature air outside the pile body 1 enters from the mounting frame 2 of one of the vents 11, and the high-temperature air inside the pile body 1 leaves from the mounting frame 2 of the other vent 11. When the charging pile is not working, the switch assembly 4 drives the blades 22 to rotate synchronously, all the blades 22 fit together, and the vents 11 are closed, preventing dust or rainwater from entering the pile body 1.
[0034] Reference Figure 2 and Figure 3 On both opposite side walls of the pile body 1, a storage body 12 extending toward the inside of the pile body 1 is integrally formed. A storage groove 13 extending into the storage body 12 is provided on the side wall of the pile body 1. The storage groove 13 is located above the vent 11. A rain shield 3 is provided in the storage groove 13. The rain shield 3 can extend out of or retract into the storage groove 13. When the charging pile is working on a rainy day, the rain shield 3 extends out of the storage groove 13 to shield the vent 11 from rain. When the charging pile is working or not working on a sunny day, the rain shield 3 retracts into the storage groove 13.
[0035] In order to protect the vent 11 from rain, refer to Figure 2 and Figure 3 The rain shield 3 includes a slide 31 and a waterproof cloth 32. The slide 31 slides with the receiving groove 13 in a direction close to or away from the receiving groove 13, and the slide 31 can extend or retract into the receiving groove 13. One end of the waterproof cloth 32 is fixedly connected to the end of the slide 31 away from the pile body 1 by adhesive, and the other end of the waterproof cloth 32 is fixedly connected to the end of the receiving groove 13 facing the outside of the pile body 1 by adhesive. A storage gap for storing the waterproof cloth 32 is reserved between the top of the slide 31 and the receiving groove 13, and the waterproof cloth 32 is also fixed to the top of the slide 31 by adhesive in the middle of the sliding direction of the slide 31.
[0036] Reference Figure 3When the rain shield 3 needs to be extended, the carriage 31 is driven to slide outward in the storage slot 13, driving the waterproof cloth 32 to unfold, thereby preventing rainwater from entering the vent 11. When the rain shield 3 does not need to be extended, the carriage 31 retracts into the storage slot 13, and the carriage 31 pulls the middle part of the waterproof cloth 32 into the storage slot 13 first, so that the waterproof cloth 32 is stably folded in the storage slot 13, and the waterproof cloth 32 can be neatly stored in the storage gap. And the waterproof cloth 32 is used for blocking water and faces the notch of the storage slot 13. In this embodiment, the storage slot 13 and the carriage 31 are both arranged in a herringbone shape to avoid water accumulation on the top of the waterproof cloth 32 as much as possible.
[0037] In order to facilitate driving all blades 22 to rotate synchronously, refer to Figure 4 The switch assembly 4 includes a rack 41 and a gear 42. The rotating shaft of the blade 22 passes through the side wall of the mounting frame 2 and is coaxially connected to the gear 42. The rack 41 slides vertically on the side wall of the mounting frame 2, and the rack 41 is meshed with the gears 42 on all blades 22 at the same time. In this embodiment, a limiting groove 411 is provided on the rack 41, and a limiting block 24 is fixedly provided on the side wall of the mounting frame 2. The top of the limiting block 24 can be against the top of the limiting groove 411, and the bottom of the limiting block 24 can be against the bottom of the limiting groove 411. When the rack 41 slides vertically, the rack 41 is meshed with the gears 42 on all blades 22, and all the gears 42 rotate synchronously, thereby realizing the synchronous opening and closing action of all blades 22.
[0038] In order to facilitate the control of the sliding movement of the rack 41 and the slide 31, refer to Figure 3 A push-out spring 131 is provided in the storage groove 13, one end of the push-out spring 131 abuts against the end wall of the storage groove 13, and the other end of the push-out spring 131 abuts against one end of the slide 31 facing the storage groove 13, and the push-out spring 131 drives the slide 31 to slide away from the storage groove 13.
[0039] Reference Figure 2 and Figure 4 The switch assembly 4 further includes a reset component 44 and a tension spring 43. One end of the tension spring 43 is connected to the bottom of the pile body 1, and the other end of the tension spring 43 is connected to the bottom of the rack 41. The tension spring 43 drives the rack 41 to approach the bottom of the inner wall of the pile body 1 to drive the adjacent blades 22 to rotate away from each other. The reset component 44 is used to drive the rack 41 away from the bottom of the pile body 1 to drive the adjacent blades 22 to rotate to fit each other.
[0040] Reference Figure 2 and Figure 4The reset component 44 includes a tension rope 441, a sliding platform 442, a roller 443, and a driving member 444. The sliding platform 442 is arranged to slide in the vertical direction in the pile body 1, and the driving member 444 is used to drive the sliding platform 442 to slide and lock the sliding platform 442. There are two rollers 443 symmetrically on the side wall of the sliding platform 442, and a tension rope 441 is sleeved on each of the two rollers 443, wherein one tension rope 441 is connected to the slide 31 and the rack 41 on one side of the pile body 1, and the other tension rope 441 is connected to the slide 31 and the rack 41 on the other side of the pile body 1. Specifically, a plurality of reversing wheels 14 are rotatably arranged on the inner wall of the pile body 1 and the mounting frame 2, and one end of the tension rope 441 is wound around the reversing wheel 14, and extends into the receiving groove 13 and is fixedly connected to the middle part of the slide 31 toward one end of the receiving groove 13. The other end of the tension rope 441 is fixedly connected to the top of the rack 41 after passing through the reversing wheel 14, and the middle part of the tension rope 441 is sleeved on the bottom side of the roller 443. The elastic force of the tension spring 43 is greater than the elastic force of the push-out spring 131.
[0041] Reference Figure 2 and Figure 4 The driving member 444 includes a servo motor 4441 and a screw rod 4442 . The screw rod 4442 is vertical and rotates in the pile body 1 . The screw rod 4442 is threadedly engaged with the sliding platform 442 . The servo motor 4441 is fixedly arranged on the inner wall of the pile body 1 . The driving shaft of the servo motor 4441 is coaxially connected with the screw rod 4442 .
[0042] In addition, a raindrop sensor 5 is fixedly arranged on the top of the pile body 1 , and the raindrop sensor 5 is electrically connected to the servo motor 4441 .
[0043] The implementation principle of a new energy heat dissipation charging pile in the embodiment of the present application is as follows: when the charging pile is not working, the servo motor 4441 drives the screw rod 4442 to rotate, the screw rod 4442 engages the sliding platform 442 and drives the sliding platform 442 to move downward, the roller 443 tightens the tension rope 441, one end of the tension rope 441 pulls the rack 41, the rack 41 overcomes the elastic force of the tension spring 43 and moves upward, so that the adjacent blades 22 rotate to fit each other and close the vent 11. The other end of the tension rope 441 pulls the slide 31, the slide 31 overcomes the elastic force of the push-out spring 131, and the slide 31 and the waterproof cloth 32 are retracted into the storage slot 13.
[0044] When the charging pile is working on a non-rainy day, the raindrop sensor 5 does not detect rain, and the servo motor 4441 drives the sliding platform 442 to move upward slightly, and the tension rope 441 is slightly loosened. Since the elastic force of the tension spring 43 is greater than the elastic force of the push-out spring 131, and the roller 443 allows the two ends of the tension rope 441 to adjust themselves, the tension spring 43 first pulls the rack 41 downward, causing the adjacent blades 22 to rotate away from each other, opening the vent 11 for heat dissipation, and the slide 31 is kept in the storage slot 13 under the action of the push-out spring 131.
[0045] When the charging pile is working in rainy days, the raindrop sensor 5 detects rain and sends a signal to the servo motor 4441, which drives the sliding platform 442 to move up significantly, and the tension rope 441 is completely relaxed. When the tension spring 43 first pulls the rack 41 down to the limit position, the tension rope 441 continues to relax, and the slide 31 quickly extends out of the storage slot 13 under the action of the push-out spring 131, and the waterproof cloth 32 is unfolded to keep out the rain.
[0046] The effective control and rain protection of the vent 11 under different working conditions are achieved, the dust accumulation on the filter 21 is reduced, the combination of rain and dust is prevented to aggravate the clogging of the filter 21, the heat dissipation effect of the charging pile is ensured, and the switching of multiple working states is achieved by only using one power source, which reduces the control cost and heat generation. In this way, the dust on the filter 21 is reduced, and rain is prevented from contacting with the dust on the filter 21 to block the filter 21 as much as possible, so as to ensure the heat dissipation effect of the charging pile.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
