[0015] The advantages of this invention compared to the prior art are:
[0016] 1. The load control unit enables monitoring and scheduling of the charging equipment, thereby optimizing the efficiency of the charging pile system and making rational use of power resources. The shell mechanism protects the charging equipment and the load control unit. The airflow circulation mechanism cools the charging equipment and the load control unit, extending their service life and improving operating efficiency. The flipping linkage mechanism can be linked with the airflow circulation mechanism to improve the cooling efficiency of the airflow circulation mechanism. The buffer mechanism acts as a buffer to avoid equipment damage caused by sudden impacts or vibrations. It also improves the smoothness of the drive components and prevents jamming, which is beneficial to protecting the safe and stable operation of the charging equipment and the load control unit.
[0017] 2. The circulating fan blows airflow at the bottom, carrying away heat and lowering the temperature of the installation cavity. This prevents the charging equipment and load control unit from overheating or becoming unstable due to high temperatures. The heat sink effectively dissipates heat through the upward airflow, enhancing the heat dissipation of the load control unit, preventing overheating, and improving operating efficiency. Guided by the inclined airflow plate, the heat-carrying airflow exits the installation cavity through the upper ventilation slot, lowering the temperature and effectively preventing heat accumulation in the cavity, which could lead to excessively high temperatures. The lower ventilation slot allows external air to enter the bottom of the installation cavity, replenishing the internal air and promoting air circulation, which helps with heat dissipation and cooling.
[0018] 3. By activating the circulating fan and driving cylinder, the sliding double-sided rack drives the linkage gear, gear mounting shaft, tilting linkage shaft, and tilting limit plate to rotate and tilt, blocking the lower ventilation slot and preventing external airflow from entering the inner cavity through the lower ventilation slot. Then, the movement of the sliding double-sided rack also causes the air inlet regulating plate to tilt, allowing external air to enter the receiving bottom cavity through the air inlet regulating port and air inlet gap for the circulating fan to draw it out. This allows the external airflow entering the receiving bottom cavity to flow upwards and discharges the hot air in the inner cavity through the upper ventilation slot, achieving a rapid cooling effect. By activating the circulating fan and driving cylinder, external airflow enters through the air inlet regulating port. Guided by the circulating fan, the air flows out through the upper ventilation slot, effectively increasing the airflow speed and volume, enhancing heat exchange between the installation cavity and the outside. The movement of the sliding double-sided rack causes the second magnetic block to move away from the first magnetic block, reducing the repulsive force between them. This allows the air inlet regulating plate to be rotated towards the circulating fan by the torsion spring. The rotation of the air inlet regulating plate causes external gas to enter the bottom side of the installation cavity through the air inlet regulating port, and then enter the receiving bottom cavity through the air inlet gap, providing gas for the circulating fan. This increases the airflow and further accelerates the discharge speed of high-temperature gas from the cavity.
[0019] 4. The buffer airbag provides a cushioning effect on the air intake regulating plate, preventing it from vibrating upon impact. When the buffer airbag is pressed against, the gas inside the buffer airbag is squeezed into the oil reservoir, causing the lubricating oil in the oil reservoir to drip onto the drain block and flow downwards, thus lubricating the sliding double-sided rack. The sliding double-sided rack can slide smoothly, thereby preventing jamming. Attached Figure Description

[0042] In one embodiment, the load control body 30 manages the power distribution and load balancing among the charging equipment bodies 20 of the charging pile. It can monitor the load status of the power network and adjust the charging power of the charging equipment bodies 20 according to demand to avoid excessive load pressure or overload. The load control body 30 can remotely monitor and schedule the charging equipment bodies 20, thereby optimizing the efficiency of the charging pile system and rationally utilizing power resources. The load control body 30 can monitor and control the charging process of the charging pile in real time and adjust according to the load status to ensure the stable operation of the charging equipment bodies 20. The housing mechanism 10 protects the charging equipment bodies 20 and the load control body 30. The airflow circulation mechanism 40 is used to cool the charging equipment bodies 20 and the load control body 30. The flipping linkage mechanism 50 can be linked with the airflow circulation mechanism 40 to adjust the air intake direction of the airflow circulation mechanism 40, thereby improving airflow efficiency. The cooling efficiency of the air circulation mechanism 40 and the buffer mechanism 60 can play a buffering role, while also improving the smoothness of the drive component 70 and preventing jamming. In this case, the load control body 30 can realize remote monitoring and scheduling of the charging equipment body 20, thereby optimizing the efficiency of the charging pile charging system and making rational use of power resources. The shell mechanism 10 can protect the charging equipment body 20 and the load control body 30. The air circulation mechanism 40 can cool the charging equipment body 20 and the load control body 30, thereby extending their service life and improving operating efficiency. The flipping linkage mechanism 50 can be linked with the air circulation mechanism 40 to improve the cooling efficiency of the air circulation mechanism 40. The buffer mechanism 60 can play a buffering role to avoid equipment damage caused by sudden impact or vibration. It can also improve the smoothness of the drive component 70 and prevent jamming, which is beneficial to protecting the safe and stable operation of the charging equipment body 20 and the load control body 30.
[0043] In one embodiment, when the ambient temperature is low and there is no need to cool the charging pile, the operator does not need to start the circulating fan 43 and the drive cylinder 71. The heat generated by the operation of the charging equipment body 20 and the load control body 30 can raise the gas temperature inside the installation cavity 111. When the temperature inside the installation cavity 111 is too high, it can be ventilated by the upper ventilation slot 141 and the lower ventilation slot 121. Since ventilation is only carried out by the upper ventilation slot 141 and the lower ventilation slot 121, the heat dissipation efficiency is low. This allows the installation cavity 111 to maintain a suitable temperature so that the charging equipment body 20 and the load control body 30 can operate normally. It can prevent the low-temperature gas from the outside from affecting the operation of the charging equipment body 20 and the load control body 30, thus improving practicality.
[0044] In another embodiment, when the ambient temperature is moderate, the operation of the charging device body 20 and the load control body 30 will generate heat in the mounting cavity 111. The high heat generated in the mounting cavity 111 will affect the operation of the charging device body 20 and the load control body 30. The operator can activate the circulating fan 43, which can draw air from the bottom of the mounting cavity 111 and blow it upwards. This upward airflow from the bottom, along with several heat sinks 31, improves the heat dissipation effect of the load control body 30, allowing for better heat dissipation. The upward airflow carries away the heat from the heat sinks 31, and the heat-carrying airflow flows to the top of the mounting cavity 111. Then, guided by the inclined guide plate 142, the heat-absorbing airflow flows upwards through the ventilation slot 141. The heated airflow is then discharged from the upper ventilation slot 141 into the mounting cavity 111, lowering the temperature inside the mounting cavity 111 and achieving a cooling effect. After the air at the bottom is drawn away by the circulating fan 43, the mounting cavity... Gas outside cavity 111 enters the bottom of mounting cavity 111 through lower ventilation slot 121. Some of the gas entering from outside the mounting cavity 111 is then driven upwards for heat dissipation and cooling, while some gas is directly discharged through lower ventilation slot 121. Lower ventilation slot 121 allows both airflow in and out. In this design, a circulating fan 43 blows airflow from the bottom to remove heat, lowering the temperature of mounting cavity 111 and preventing overheating or malfunction of the charging device body 20 and load control body 30 due to high temperatures. The heat sink 31 can effectively dissipate heat through upward airflow, which can enhance the heat dissipation effect of the load control body 30, prevent it from overheating and improve operating efficiency. Guided by the inclined air intake plate 142, the airflow that carries away heat can be discharged from the mounting cavity 111 through the upper ventilation slot 141 to reduce the temperature, which can effectively prevent heat from accumulating in the cavity and causing the temperature to be too high. The lower ventilation slot 121 can allow external air to enter the bottom of the mounting cavity 111, which can replenish the air inside the cavity and promote air circulation, which helps to dissipate heat and cool down.
[0045] In another embodiment, when the external temperature is high, it will affect the temperature inside the mounting cavity 111. Combined with the heat generated by the charging device body 20 and the load control body 30 during operation, the temperature inside the mounting cavity 111 will be even higher. Therefore, it is necessary to promptly vent the gas from the mounting cavity 111. The operator can start the drive cylinder 71 simultaneously with starting the circulating fan 43. When the drive cylinder 71 is started, it can drive the sliding double-sided rack 72 to move away from the drive cylinder 71. The movement of the sliding double-sided rack 72 can drive the two linkage gears 84 to rotate. The linkage gears 84 can drive the gear mounting shaft 83 to rotate. The gear mounting shaft 83 can drive the tilting linkage shaft 81 to rotate via the transmission belt 85. The rotating linkage shaft 81 can drive the flipping limit plate 82 to flip, thereby blocking several lower ventilation slots 121. At this time, the lower ventilation slots 121 cannot take in or take out air. When the sliding double-sided rack 72 moves, it will drive the second magnetic block 75 to move. When the second magnetic block 75 moves, it will move away from the first magnetic block 124. The second magnetic block 75 moving away from the first magnetic block 124 reduces the repulsive force between the two. After the repulsive force is reduced, the air inlet regulating plate 123 will flip in the direction of the circulating fan 43 under the action of the torsion spring. After the air inlet regulating plate 123 flips, the air outside the mounting cavity 111 can enter the bottom side of the mounting cavity 111 through the air inlet regulating port 122, and then enter the receiving cavity through the air inlet gap 125. The bottom cavity 112 is supplied with air drawn by the circulating fan 43. The circulating fan 43 causes the external airflow entering the bottom cavity 112 to flow upwards, while the airflow inside the mounting cavity 111 flows upwards through the circulating fan 43 and flows out through the inclined guide plate 142 from the upper ventilation slot 141, which accelerates the discharge of high-temperature gas from the mounting cavity 111. In this case, by starting the circulating fan 43 and driving the cylinder 71, the sliding double-sided rack 72 drives the linkage gear 84, gear mounting shaft 83, flip linkage shaft 81 and flip limit plate 82 to rotate and flip, blocking the lower ventilation slot 121 and preventing external airflow from entering the inner cavity through the lower ventilation slot 121. Then, the movement of the sliding double-sided rack 72 also causes the air inlet regulating plate 123 to flip, allowing external airflow to flow out. Gas enters the receiving cavity 112 through the air inlet regulating port 122 and the air inlet gap 125 for extraction by the circulating fan 43. This allows the external airflow entering the receiving cavity 112 to flow upwards and discharges the hot gas in the cavity through the upper ventilation slot 141, achieving a rapid cooling effect. By starting the circulating fan 43 and driving the cylinder 71, external airflow enters through the air inlet regulating port 122, is guided by the circulating fan 43, and flows out through the upper ventilation slot 141. This effectively increases the airflow speed and volume, enhancing heat exchange between the installation cavity 111 and the outside environment. The movement of the sliding double-sided rack 72 causes the second magnetic block 75 to move away from the first magnetic block 124, reducing the repulsive force between them and allowing the air inlet regulating plate 123 to be subjected to the action of the torsion spring.The rotation of the air inlet regulating plate 123 towards the circulating fan 43 causes external gas to enter the bottom side of the mounting cavity 111 through the air inlet regulating port 122, and then enter the receiving bottom cavity 112 through the air inlet gap 125, providing gas for the circulating fan 43. This increases the airflow and further accelerates the discharge speed of the high-temperature gas from the cavity.
[0046] When the air inlet regulating plate 123 flips towards the circulating fan 43 under the action of the torsion spring, it abuts against the two buffer airbags 61. The buffer airbags 61 can buffer the air inlet regulating plate 123 to prevent it from vibrating due to strong collision. When the buffer airbags 61 are abutted, they are compressed. When the buffer airbags 61 are compressed, the gas in the buffer airbags 61 can enter the oil reservoir 62 through the vent groove 421. This allows the lubricating oil in the oil reservoir 62 to drip down through the permeation micropores 621. The lubricating oil drips onto the guide block 63 and flows downward, eventually dripping onto the wedge-shaped guide block 73. The lubricating oil flows to both sides through the guide slope 731, lubricating the sliding double-sided rack 72, making the sliding double-sided rack 72 slide more smoothly. The sliding double-sided rack 72 is designed to prevent jamming during movement, thus improving work efficiency. When the sliding double-sided rack 72 moves to its maximum distance, the inclined surface 741 abuts against the bottom end of the guide block 63, preventing the lubricant from dripping over the wedge-shaped limit block 74 onto the second magnetic block 75 and affecting the repulsive force of the second magnetic block 75. In this case, the buffer airbag 61 provides a buffering effect on the air intake regulating plate 123, preventing it from vibrating due to collision. When the buffer airbag 61 is abutted, the gas inside the buffer airbag 61 is squeezed into the oil reservoir 62, causing the lubricant in the oil reservoir 62 to drip onto the guide block 63 and flow downwards, thus providing a lubricating effect on the sliding double-sided rack 72. The sliding double-sided rack 72 can slide smoothly, thereby avoiding jamming.

[0048] This invention can achieve the following: 1. The load control body 30 can monitor and schedule the charging equipment body 20, thereby optimizing the efficiency of the charging pile charging system and making reasonable use of power resources. The shell mechanism 10 can protect the charging equipment body 20 and the load control body 30. The airflow circulation mechanism 40 can cool the charging equipment body 20 and the load control body 30, thereby extending their service life and improving operating efficiency. The flipping linkage mechanism 50 can be linked with the airflow circulation mechanism 40 to improve the cooling efficiency of the airflow circulation mechanism 40. The buffer mechanism 60 can play a buffering role to avoid equipment damage caused by sudden impact or vibration. It can also improve the smoothness of the drive component 70 and prevent jamming, which is beneficial to protecting the safe and stable operation of the charging equipment body 20 and the load control body 30.
[0049] 2. The airflow at the bottom, blown by the circulating fan 43, carries away heat, thereby lowering the temperature of the mounting cavity 111. This prevents the charging device body 20 and the load control body 30 from overheating or becoming unstable due to high temperatures. The heat sink 31 effectively dissipates heat through the upward airflow, enhancing the heat dissipation effect of the load control body 30, preventing overheating and improving operating efficiency. Guided by the inclined guide plate 142, the heat-carrying airflow can exit from the mounting cavity 111 through the upper ventilation slot 141, reducing the temperature and effectively preventing heat accumulation in the cavity, which could lead to excessively high temperatures. The lower ventilation slot 121 allows external air to enter the bottom of the mounting cavity 111, replenishing the air inside the cavity and promoting air circulation, which helps to dissipate heat and lower the temperature.
[0050] 3. By starting the circulating fan 43 and the drive cylinder 71, the sliding double-sided rack 72 drives the linkage gear 84, gear mounting shaft 83, flip linkage shaft 81, and flip limit plate 82 to rotate and flip, blocking the lower ventilation slot 121 and preventing external airflow from entering the inner cavity through the lower ventilation slot 121. Then, the movement of the sliding double-sided rack 72 also causes the air inlet regulating plate 123 to flip, allowing external gas to enter the receiving bottom cavity 112 through the air inlet regulating port 122 and the air inlet gap 125 for the circulating fan 43 to draw it out. This allows the external airflow entering the receiving bottom cavity 112 to flow upward and the hot gas in the inner cavity to be discharged from the upper ventilation slot 141, achieving a rapid cooling effect. By starting the circulating fan 43 and the drive cylinder 71, the external airflow is directed from the air inlet regulating port... The air enters through 122, is guided by the circulating fan 43, and flows out through the upper ventilation slot 141, which can effectively improve the airflow speed and volume, enhance the heat exchange between the installation cavity 111 and the outside. The movement of the sliding double-sided rack 72 will cause the second magnetic block 75 to move away from the first magnetic block 124, thereby reducing the repulsive force between the two. This allows the air inlet regulating plate 123 to be rotated towards the circulating fan 43 under the action of the torsion spring. The rotation of the air inlet regulating plate 123 will cause the external gas to enter the bottom side of the installation cavity 111 through the air inlet regulating port 122, and then enter the receiving bottom cavity 112 through the air inlet gap 125, providing gas for the circulating fan 43, which can increase the airflow and further accelerate the discharge speed of the high temperature gas in the cavity.
[0051] 4. The buffer airbag 61 can provide a buffering effect on the air intake regulating plate 123 to prevent it from vibrating due to collision. When the buffer airbag 61 is held in place, the gas inside the buffer airbag 61 will be squeezed into the oil reservoir 62, which will cause the lubricating oil in the oil reservoir 62 to drip onto the drain block 63 and flow downward, thus providing a lubricating effect on the sliding double-sided rack 72. The sliding double-sided rack 72 can slide smoothly, thereby avoiding the occurrence of jamming.
