Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle power supply, and in particular to a waterproof new energy vehicle charging pile with efficient heat dissipation. Background Art

[0002] Existing charging piles include a housing and a power supply device. The power supply device is fixedly mounted within the housing, with heat dissipation holes on opposite sides of the housing. Multiple cooling fans are fixedly mounted within the heat dissipation holes, and filters are fixedly mounted on the housing, corresponding to the openings of the heat dissipation holes and close to the cooling fans. A charging cable is mounted outside the housing, one end of which is connected to the power supply device, and the other end is equipped with a charging plug compatible with the charging port of a new energy vehicle. The existing housing lacks sufficient airflow, resulting in inadequate heat dissipation. Furthermore, in rainy weather, rainwater easily seeps into the housing through the filters, damaging the power supply device.

[0003] Chinese patent CN116176324B discloses a new energy vehicle charging pile with good waterproof and heat dissipation effects, including a shell and a power supply device body installed in the shell, one side of the shell is provided with an air inlet and the other side is provided with an air outlet, the openings of the air inlet and the air outlet are both installed with mounting frames, a plurality of baffles are installed in the mounting frame at intervals in the vertical direction, and the baffles are inclined downward from the side close to the inside of the shell toward the outside of the shell; a heat dissipation fan is installed on the side of the mounting frame located at the air outlet and facing inward, and a buffer cavity is formed between the side of the power supply device body corresponding to the air outlet and the heat dissipation fan.

[0004] Although the above solution can improve the heat dissipation efficiency, it uses enhanced sealing to prevent rainwater from entering the outer shell on rainy days, which will cause the temperature inside the outer shell to be unable to dissipate in time, that is, the heat dissipation of the charging pile will be greatly reduced on rainy days, and the heat dissipation function in the above solution needs to be driven by electricity, which results in higher power consumption. Summary of the Invention

[0005] In response to the above problems, a waterproof new energy vehicle charging pile with efficient heat dissipation is provided. When it rains outside, rainwater flows into the water collecting shell through a drainage assembly arranged on the upper part of the water collecting shell. The sliding plate located in the water collecting shell slides relative to the water collecting shell. As rainwater continues to flow in, the sliding plate overcomes the elastic force of the first spring and continues to descend. Finally, the sliding plate slides to the bottom of the connection between the second connecting pipe and the water collecting shell. At this time, the water on the upper part of the sliding plate can flow into the first connecting pipe through the second connecting pipe. The first connecting pipe is arranged inside the outer shell, so that the temperature inside the outer shell can be lowered by the flowing water. At the same time, after the sliding plate descends, it will also drive the transmission device. The sliding plate drives the heat dissipation shell to rotate through the transmission device, so that the heat dissipation shell is rotated out of the outer shell, thereby further achieving the heat dissipation effect. The power source is entirely the pressure generated by rainwater, which avoids energy use and reduces energy consumption.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with a water collecting shell, a first connecting pipe, a second connecting pipe, a sliding plate, a first spring, a transmission device, a heat dissipation shell and a drainage component. When rain occurs outside, rainwater flows into the water collecting shell through the drainage component arranged on the upper part of the water collecting shell. The sliding plate located in the water collecting shell slides relative to the water collecting shell. After the rainwater continues to flow in, the sliding plate overcomes the elastic force of the first spring and continuously descends. Finally, the sliding plate slides to the bottom of the connection between the second connecting pipe and the water collecting shell. At this time, the water on the upper part of the sliding plate can flow into the first connecting pipe through the second connecting pipe. The first connecting pipe is arranged inside the shell. In this way, the temperature inside the shell can be reduced by the flowing water. At the same time, after the sliding plate descends, it will also drive the transmission device. The sliding plate drives the heat dissipation shell to rotate through the transmission device, so that the heat dissipation shell is rotated out of the shell, thereby further achieving the heat dissipation effect. The power source is entirely the pressure generated by the rainwater, which avoids energy use and reduces energy consumption.

[0018] 2. Taking into account the characteristics of sunny and rainy days, a specific mechanical structure was set up: on sunny days, the drainage plates are in a closed state close to each other to prevent excessive dust accumulation, while also avoiding direct sunlight from the outside, which would cause the shell temperature to be too high. At this time, the heat dissipation shell is in a closed state, which also effectively reduces the amount of dust entering the shell. At the same time, a motor and a fan are used for active heat dissipation. On rainy days, the gravity of the collected rainwater is used to drive the two drainage plates to rotate and open, thereby improving the rain collection efficiency and better utilizing rainwater for heat dissipation. At the same time, it drives the heat dissipation shell to rotate so that the heat dissipation shell can be rotated out of the shell, further achieving the heat dissipation effect. In summary, through the clever structural setting, it ensures dustproof and active heat dissipation on sunny days, as well as waterproof and energy-saving heat dissipation on rainy days.

[0019] 3. Through clever detailing, the overall rainproof and heat dissipation effects are enhanced. A charging device position control device is provided. On rainy days, the internal charging device is lifted upward, away from the rotated heat dissipation housing, to avoid contact with moisture. On sunny days, the internal charging device is positioned downward, close to the fan, to better dissipate heat. A snap-in block, snap-in slot, first spring, and second spring structure are also provided to ensure that when there is heavy rainfall, the sliding plate does not need to be repeatedly raised and lowered. A steady flow of water flows into the second connecting pipe, enhancing the heat dissipation effect. When the rain turns sunny, as the rain gradually drains, the gravity of the rain on the sliding plate gradually decreases, causing the sliding plate to pop out of the snap-in block and return to its initial position.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1-Figure 3 and Figure 8 : A waterproof new energy vehicle charging pile with efficient heat dissipation, comprising a shell 1 and a heat dissipation device 2; the heat dissipation device 2 comprises a water collecting shell 21, a first connecting pipe 211, a second connecting pipe 212, a sliding plate 22, a first spring 221, a transmission device 23, a heat dissipation shell 24 and a drainage component 25; the water collecting shell 21 is arranged on the upper part of the shell 1, and the water collecting shell 21 can collect rainwater; the first connecting pipe 211 is arranged below the water collecting shell 21 along the height direction of the shell 1; the two ends of the second connecting pipe 212 are respectively connected to the upper part of the first connecting pipe 211 and the side wall of the water collecting shell 21, and the second connecting pipe 212 is communicated with the water collecting shell 21; the sliding plate 22 is slidably arranged in the water collecting shell 21 along the height direction of the water collecting shell 21, and the second connecting pipe 212 is connected to the water collecting shell 21 The intermediate connection is located in the sliding area of ​​the sliding plate 22, and the sliding plate 22 can absorb and dissipate the heat in the outer shell 1; the first spring 221 is arranged at the bottom of the sliding plate 22, and the first spring 221 is compressed when the sliding plate 22 descends along the height direction of the water collecting shell 21; the heat dissipation shell 24 is rotatably arranged on the side wall of the outer shell 1, and a cooling device 27 is provided on the side wall of the outer shell 1; the transmission device 23 is arranged on the outer shell 1, and when the sliding plate 22 descends, the heat dissipation shell 24 can be driven to rotate through the transmission device 23, and the transmission device 23 can absorb the heat in the outer shell 1 and dissipate it through the sliding plate 22; the drainage component 25 is arranged on the upper part of the water collecting shell 21, and the drainage component 25 can control rainwater to enter the water collecting shell 21, and the sliding plate 22 drives the drainage component 25 to operate through the transmission device 23.

[0034] The heat dissipation shell 24 is in a closed state on sunny days, that is, the heat in the shell 1 cannot be dissipated through the heat dissipation shell 24. The shell 1 itself is provided with a cooling device 27. The cooling device 27 can make the air in the shell 1 flow to the outside. When heat dissipation is in progress, the air inside the shell 1 will be dissipated, and the outside air will also partially flow into the shell 1. The heat dissipation shell 24 is in a closed state in order to reduce the amount of dust entering the shell 1. Dust attached to the components in the shell 1 will hinder the normal heat dissipation of the components. In this way, on sunny days, only the cooling device 27 is in operation. When it rains outside, rainwater flows into the water collecting shell 21 through the drainage assembly 25 arranged on the upper part of the water collecting shell 21, and the sliding plate 22 located in the water collecting shell 21 slides relative to the water collecting shell 21. After the rainwater continues to flow in, the sliding plate 22 overcomes the elastic force of the first spring 221 and continues to fall. Finally, the sliding plate 22 slides to the bottom of the connection between the second connecting pipe 212 and the water collecting shell 21. At this time, the water on the upper part of the sliding plate 22 can flow into the first connecting pipe 211 through the second connecting pipe 212. The first connecting pipe 211 is arranged on the outer shell 1 The interior of the housing 1 is thus cooled by the flowing water. At the same time, after the sliding plate 22 descends, the transmission device 23 is also driven. The sliding plate 22 drives the heat dissipation shell 24 to rotate through the transmission device 23, so that the heat dissipation shell 24 is rotated out of the housing 1, thereby further achieving the heat dissipation effect. Since the outside world is in a rainy state and the air humidity is high, it is difficult for dust to be blown up by the wind. In this way, the dust from the outside will not enter the housing 1 through the heat dissipation shell 24, and the power source is entirely the pressure generated by rainwater, which avoids energy use and reduces energy consumption. As the rain stops, the sliding plate 22 will also rise under the elastic force of the first spring 221. When the sliding plate 22 moves to above the connection between the second connecting pipe 212 and the outer shell 1, the water on the upper part of the sliding plate 22 will not be able to flow out from the second connecting pipe 212. At this time, the heat inside the outer shell 1 will gradually rise, and the heated air will also rise, causing the temperature at the bottom of the water collecting shell 21 to gradually increase, thereby causing the temperature of the transmission device 23 to rise. The transmission device 23 dissipates the heat through the sliding plate 22, and the water on the sliding plate 22 will also evaporate naturally. When the water evaporates, it will take away a lot of heat, which can also achieve the purpose of cooling the temperature inside the outer shell 1.

[0035] Reference Figures 1-4 : The drainage assembly 25 includes a drainage plate 251 and a water collecting trough 252; there are two drainage plates 251, which are symmetrically hinged on both sides of the opening of the water collecting shell 21, and the two drainage plates 251 can approach and move away from each other under the drive of the transmission device 23, and the two drainage plates 251 form a "human" structure when they approach each other; the water collecting trough 252 is set on the side wall of the water collecting shell 21 below the drainage plate 251, and the water collecting trough 252 can collect the water flow guided by the drainage plate 251 and discharge it into the water collecting shell 21.

[0036] When the weather is sunny, the drainage plates 251 are in a closed state close to each other. The closed drainage plates 251 can prevent excessive dust from accumulating on the sliding plate 22, and can also prevent external sunlight from directly shining on the sliding plate 22, so that the heat dissipation of the housing 1 is affected. When the weather changes from sunny to rainy, the transmission device 23 rotates under the drive of the sliding plate 22, so that the two drainage plates 251 rotate and open, thereby improving the rain collection efficiency. At this time, there is very little dust outside, and there is no need to block the external dust.

[0037] Reference Figure 3 : The drainage assembly 25 further includes a connecting membrane 253; the connecting membrane 253 is disposed on one side of the two drainage plates 251 close to each other, and the connecting membrane 253 is used to shield the gap at the hinge of the connecting membrane 253 and the water collecting shell 21.

[0038] After the sliding plate 22 drops, the transmission device 23 drives the two drainage plates 251 to open, and the water collection capacity can be expanded at this time. However, since the drainage plate 251 is hinged to the water collection shell 21, after the drainage plate 251 receives rainwater, the rainwater will flow out from the hinge when passing through the hinge between the drainage plate 251 and the water collection shell 21, and thus cannot enter the water collection shell 21. By providing a connecting membrane 253, the above situation can be prevented from occurring. At the same time, it can also avoid rust on the hinge between the drainage plate 251 and the water collection shell 21 caused by rainwater, thereby ensuring the normal rotation of the drainage plate 251.

[0039] Reference Figure 2 、 Figure 3 and Figure 5 The transmission device 23 includes an extension rod 231, a driving rod 2311, a first synchronous belt 232, a first synchronous wheel 233 and a transmission assembly 234; the extension rod 231 is vertically fixed at the bottom of the sliding plate 22, and the extension rod 231 passes through the bottom of the water collecting shell 21; the driving rod 2311 is horizontally fixed on the side wall of the extension rod 231; the first synchronous belt 232 is set in the housing 1 along the height direction of the housing 1, and the end of the driving rod 2311 away from the extension rod 231 is fixed to the first synchronous belt 232 Connection; a plurality of first synchronous wheels 233 are provided, and the first synchronous wheels 233 are arranged in the first synchronous belt 232 along the height direction of the shell 1. The first synchronous wheel 233 and the first synchronous belt 232 are matched in transmission, and the end of the first synchronous wheel 233 that is not in contact with the two ends of the first synchronous belt 232 is connected to the heat dissipation shell 24; the two ends of the transmission assembly 234 are respectively connected to the uppermost first synchronous wheel 233 and the guide plate 251, and the uppermost first synchronous wheel 233 drives the guide plate 251 to rotate through the transmission assembly 234.

[0040] When the sliding plate 22 is lowered under the pressure of the continuously influx of water, the extension rod 231 arranged at the lower part of the sliding plate 22 will also be lowered synchronously, and the driving rod 2311 fixedly connected to the extension rod 231 will be lowered synchronously with the extension rod 231, so that the first synchronous belt 232 will be driven to rotate, and the first synchronous wheel 233 that cooperates with the first synchronous belt 232 for transmission will also rotate synchronously. A pressure wheel is provided on one side of the first synchronous wheel 233 located in the middle part of the first synchronous belt 232 to ensure the driving force of the first synchronous belt 232 on the first synchronous wheel 233. The first synchronous wheel 233 located on the uppermost side can drive the guide plate 251 to rotate through the transmission assembly 234.

[0041] Reference Figure 5 、 Figure 7 and Figure 10 : The transmission assembly 234 includes a second synchronous belt 2341, a second synchronous wheel 2342, a first gear 2343 and a second gear 2344; the first gear 2343 is arranged on one side of the water collecting shell 21 along the hinge axis of the guide plate 251 and the water collecting shell 21, and the first gear 2343 is fixedly connected to the water collecting shell 21; the second gear 2344 is arranged on the lower side of the first gear 2343, and the second gear 2344 and the first gear 2343 are engaged with each other; there are two second synchronous wheels 2342, and the two second synchronous wheels 2342 are respectively arranged on the second gear 2344 and the end of the first gear 2343 on the uppermost side; the two ends of the second synchronous belt 2341 are respectively mounted on the two second synchronous wheels 2342, and the second synchronous belt 2341 and the second synchronous wheel 2342 are matched for transmission.

[0042] When the first synchronous wheel 233 rotates, the second synchronous wheel 2342 rotates accordingly, thereby driving the second synchronous belt 2341 to rotate. The rotating second synchronous wheel 2342 drives the second gear 2344 to rotate, and then the first gear 2343 engaged with the second gear 2344 is also driven to rotate, thereby realizing the rotation of the guide plate 251.

[0043] Reference Figure 6 and Figure 8 : The heat dissipation device 2 also includes a pressure limiting device 26, which includes a second spring 261, a clamping block 262 and a clamping groove; a receiving groove is horizontally opened on the inner wall of the outer shell 1, and the receiving groove is located below the connection between the second connecting pipe 212 and the water collecting shell 21. The clamping block 262 is slidably set in the receiving groove along the depth direction of the receiving groove, and there is a gap between the clamping block 262 and the bottom of the receiving groove; the second spring 261 is set in the gap; the clamping groove is opened on the side wall of the sliding plate 22, and the clamping groove and the clamping block 262 are clamped together.

[0044] The first spring 221 and the second spring 261 are selected and tested so that their elastic forces meet the following requirements: when the rainfall level or rainfall is higher than a certain level, the water flow can press the sliding plate 22 to the lowest point, and the clamping block 262 is clamped into the clamping groove under the action of the second spring 261, so that the water on the sliding plate 22 can continuously flow into the second connecting pipe 212. The three forces that overcome the elastic force of the first spring 221 are the pressure of the second spring 261 on the clamping groove through the clamping block 262, The gravity of the sliding plate 22 and the gravity of the water on the sliding plate 22, when there is abundant rainfall outside, there is always enough rainwater falling on the upper part of the sliding plate 22, the first spring 221 is always in a compressed state, the sliding plate 22 does not need to be repeatedly raised and lowered, and new water always flows into the second connecting pipe 212. When the rain turns clear, as the water gradually drains away, the gravity of the water on the sliding plate 22 gradually decreases, so the first spring 221 will pop the sliding plate 22 out of the clamping block 262, and the sliding plate 22 returns to its initial state.

[0045] Reference Figure 2 、 Figure 4 and Figure 8 : The heat dissipation device 2 further includes a drainage groove 213 and an inclined block 214; the drainage groove 213 is provided through the side wall of the bottom of the water collecting shell 21; the inclined block 214 is a "human" structure, and the inclined block 214 is fixedly provided at the bottom of the water collecting shell 21.

[0046] Since the sliding plate 22 and the water collecting shell 21 are in sliding cooperation, rainwater from the outside enters the water collecting shell 21 and is received by the sliding plate 22. Regardless of the sealing between the sliding plate 22 and the water collecting shell 21, a small amount of water will flow out from the gap between the sliding plate 22 and the water collecting shell 21, and will gather at the bottom of the water collecting shell 21. If the inclined block 214 is not provided, the accumulated water cannot be discharged in time. After the inclined block 214 is provided, the rainwater will be discharged from the drainage groove 213 under the guidance of the inclined block 214.

[0047] Reference Figure 2 : The cooling device 27 further includes a fan 271; the fan 271 is rotatably disposed on the side wall of the housing 1, and a motor is provided on one side of the fan 271 for driving the fan 271 to rotate.

[0048] The rotating fan 271 can discharge the heat inside the shell 1 to the outside, thereby reducing the heat inside the shell 1 and achieving the heat dissipation effect. It is worth noting that the fan 271 will only run on sunny days. When rainwater enters the water collecting shell 21 and causes the sliding plate 22 to slide down, the fan 271 will not run, which can reduce energy consumption.

[0049] Reference Figure 3: The transmission assembly 234 also includes a first waterproof cover 2345; the first waterproof cover 2345 is sleeved on the outside of the second synchronous belt 2341.

[0050] Since the second synchronous belt 2341 passes through the upper part of the housing 1 to realize transmission, if the first waterproof cover 2345 is not provided on the outer side of the second synchronous belt 2341, when it rains, rainwater from the outside will flow into the interior of the housing 1 along the gap between the second synchronous belt 2341 and the upper part of the housing 1.

[0051] Reference Figure 1 and Figure 2 : The heat dissipation device 2 further includes a second waterproof cover 2711; the second waterproof cover 2711 is provided on the side wall of the housing 1 on one side of the fan 271, and the lower portion of the second waterproof cover 2711 has an opening, the opening communicating with the fan 271.

[0052] The second waterproof cover 2711 can prevent rainwater from flowing into the housing 1 through the fan 271 under the influence of wind during rainfall.

[0053] Not shown in the figure, a position control device can also be provided to adjust and control the height position of the charging device in the charging pile. On rainy days, the internal charging device is lifted upward, away from the rotated heat dissipation shell 24 and the lower opening to avoid contact with water vapor; on sunny days, the internal charging device is moved downward to be close to the position of the fan 271, so as to achieve better heat dissipation and avoid dust accumulation.
