[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] See also Figure 1-7 As shown in the figure, the reference specification provided in this embodiment Figure 1-7 , a charging pile according to an embodiment of the present invention, such as Figure 1 As shown, it includes a main body 1, a liquid cooling heat dissipation mechanism 2 is fixedly installed on one side of the main body 1; Figure 2 As shown, an air-cooled heat dissipation mechanism 3 is slidably installed on one side of the liquid-cooled heat dissipation mechanism 2, and an auxiliary heat dissipation mechanism 4 is provided inside the liquid-cooled heat dissipation mechanism 2; the main mechanism 1 includes a charging pile body 101, a support frame 102 is fixedly installed on the bottom of the charging pile body 101, and a charging line 103 is electrically connected to the bottom of the charging pile body 101. The liquid-cooled heat dissipation mechanism 2 includes a positioning frame 21 fixedly installed on one side of the charging pile body 101, and a hollow plate 22 is fixedly installed on one side of the positioning frame 21. Figure 3 As shown, a cavity is formed between the positioning frame 21 and the hollow plate 22, and a plurality of air guide grooves 23 connected to the inner cavity of the charging pile body 101 are provided on the side of the positioning frame 21 away from the hollow plate 22. The purpose of this arrangement is to keep the positioning frame 21 and the inner cavity of the charging pile body 101 connected to each other, so as to discharge the heat generated inside the charging pile body 101 during operation through the air guide grooves 23 to the inner cavity of the positioning frame 21, thereby increasing the internal space of the charging pile body 101 and increasing the heat circulation space.

[0021] At the same time, combined Figure 6-7 As shown, the air-cooling heat dissipation mechanism 3 includes a positioning hollow tube 31 that is slidably connected to the hollow plate 22. One end of the positioning hollow tube 31 extending out of the outer wall of the hollow plate 22 is connected to an air guide cover 32. The end of the positioning hollow tube 31 away from the air guide cover 32 is connected to a heat dissipation fan 33. A connecting rod 34 is fixedly connected to the vertical center line position of the heat dissipation fan 33. One end of the connecting rod 34 extending out of the outer wall of the air guide cover 32 is fixedly connected to a supporting bracket 35. A first dust removal scraper 36 is fixedly installed on one side of the supporting bracket 35.

[0022] It can be understood that a number of ventilation holes are provided on the outer circumferential surface of the air guide cover 32. When the charging pile needs to dissipate heat, the cooling fan 33 can be started to allow the outside air to flow through the outer circumference of the air guide cover 32 to the inner cavity of the positioning hollow tube 31, and enter the inner cavity of the positioning frame 21 to blow air on the surface of the liquid cooling circulation component 24. At the same time, when the cooling fan 33 rotates to exhaust air, the supporting bracket 35 and the first dust removal scraper 36 are driven to rotate through the connecting rod 34, and the first dust removal scraper 36 can be rotated and moved to fit the outer circumferential surface of the air guide cover 32, thereby synchronously scraping off the dust adhering to and blocking the outer circumferential surface of the air guide cover 32 to avoid affecting the air circulation and improve the heat dissipation effect.

[0023] Furthermore, a liquid cooling circulation assembly 24 is fixedly mounted on the inner wall of the positioning frame 21. One side of the liquid cooling circulation assembly 24 is connected to a liquid outlet pipe 25 extending into the inner cavity of the charging pile body 101. Figure 4-5 As shown, one end of the liquid outlet pipe 25 extending into the inner cavity of the charging pile body 101 is connected to a cooling pipe 26 , and one end of the cooling pipe 26 is connected to a liquid inlet pipe 27 connected to the liquid cooling circulation component 24 .

[0024] It is understandable that in actual use, reference Figure 6 As shown, the cooling pipe 26 is arranged around the inner cavity of the charging pile body 101. By starting the liquid cooling circulation component 24, the coolant is introduced into the cooling pipe 26 through the liquid outlet pipe 25 and circulated, and then enters the liquid cooling circulation component 24 through the liquid inlet pipe 27 for circulation. When the coolant circulates in the inner cavity of the cooling pipe 26, it is combined with the cooling pipe 26 to surround the periphery of the components that need heat dissipation in the inner cavity of the charging pile body 101, so as to effectively absorb and take away heat, thereby achieving a preliminary heat dissipation effect.

[0025] Specifically, the liquid cooling circulation component 24 pumps the coolant so that it flows into the cooling pipe 26 along the liquid outlet pipe 25. The cooling pipe 26 is designed to surround the heat dissipation components in the inner cavity of the charging pile body 101, so that the coolant can directly contact the surface of the heat dissipation components and absorb the heat generated by them. Subsequently, the coolant that has absorbed the heat flows back to the liquid cooling circulation component 24 through the liquid inlet pipe 27 for cooling treatment, and is then circulated back to the cooling pipe 26 by the circulation pump to form a closed-loop system; through this circulating flow, the coolant can continuously take away the heat generated by the heat dissipation components to ensure heat dissipation efficiency; at the same time, since the cooling pipe 26 surrounds the components that need heat dissipation, the coolant can evenly cover and cool the entire surface of the component to avoid local overheating; this design not only improves the cooling effect, but also extends the service life of the charging pile.

[0026] In addition, the liquid cooling circulation component 24 remains sealed during operation to prevent the entry of external dust and pollutants, ensuring the purity of the coolant and the efficient operation of the system. Through this design, the charging pile of the present invention can maintain a stable operating temperature even when running at high load, thereby improving the reliability and durability of the equipment and reducing the failure rate and maintenance costs caused by poor heat dissipation.

[0027] Further, refer to Figure 7 As shown, a first limiting slide groove 28 is vertically arranged on one side of the hollow plate 22, and the positioning hollow tube 31 penetrates the first limiting slide groove 28 and is slidably installed in the inner cavity of the first limiting slide groove 28. The outer wall of the positioning hollow tube 31 is fixedly installed with a second dust removal scraper 37. In actual use, by driving the positioning hollow tube 31 to slide as a whole in the inner cavity of the first limiting slide groove 28, the second dust removal scraper 37 can be synchronously driven to translate on the outer surface of the hollow plate 22, thereby scraping off dust and impurities adhered to the outer surface of the hollow plate 22, thereby playing a role in dust prevention again.

[0028] Furthermore, at the same time, second limiting grooves 29 are opened on both sides of the positioning frame 21, and the inner cavities of the two second limiting grooves 29 are slidably installed with connecting slides 38 fixedly connected to the second dust removal scraper 37. The purpose of this arrangement is to make the overall movement of the second dust removal scraper 37 more stable and smooth.

[0029] Further preferably, an auxiliary heat dissipation mechanism 4 is provided in the liquid-cooled heat dissipation mechanism 2; the auxiliary heat dissipation mechanism 4 includes two threaded screws 41 rotatably installed in the positioning frame 21, the threaded screws 41 are respectively threadedly connected to the connecting slide 38, and one end of the threaded screw 41 extending out of the bottom of the positioning frame 21 is fixedly connected to a third transmission gear 47, and the third transmission gears 47 are connected by a second transmission belt 48, and one end of the threaded screw 41 is fixedly connected to a stepper motor for driving it to rotate.

[0030] Specifically, combined Figure 7 and Figure 4-5 As shown, the auxiliary heat dissipation mechanism 4 includes a threaded screw 41 respectively connected to the two engaging slides 38, and the two threaded screws 41 are rotatably mounted in the inner cavity of the positioning frame 21. At the same time, combined with Figure 4 As shown, one end of the two threaded screws 41 extending out of the outer wall of the positioning frame 21 is fixedly connected to the third transmission gear 47, and the outer walls of the two third transmission gears 47 are fixedly installed with a second transmission belt 48, wherein one end of a threaded screw 41 is fixedly connected to a stepper motor for driving it to rotate.

[0031] It is understandable that the purpose of this arrangement is to enable the stepper motor to start driving one threaded screw 41 to rotate, combined with the arrangement of the third transmission gear 47 and the second transmission belt 48, to drive the other threaded screw 41 to rotate synchronously, thereby driving the two engaging slides 38 to move synchronously. Figure 4 and Figure 7 As shown, in actual use, by driving the rotation of the threaded screw 41, the connecting slide 38 can be synchronously driven to slide in the limiting slide groove, so that the entire system is more efficient in heat dissipation. This linkage design enables the second dust removal scraper 37 installed on the slide 38 to move synchronously when the heat dissipation fan 33 is operating, to scrape off the dust in the heat dissipation path, ensure the cleanliness of the ventilation holes and the air guide cover, thereby avoiding the problem that traditional heat dissipation air can only blow air to a single range, resulting in poor overall heat dissipation efficiency.

[0032] Specifically, the stepper motor drives a threaded screw 41 to rotate, driving the transmission gear 47 and the transmission belt 48, so that the other threaded screw 41 rotates synchronously, and then drives the dust removal scraper 37 installed on the slide 38 to slide synchronously. In this way, during the heat dissipation process, the dust removal scraper can remove the dust in the heat dissipation channel to ensure the smooth and efficient heat dissipation system. Through this design, the stability and efficiency of the heat dissipation system of the charging pile are ensured when it is running at high load, effectively extending the service life of the equipment, while also reducing the maintenance requirements caused by dust accumulation, and improving the overall work efficiency and reliability of the charging pile. This synchronous design of heat dissipation and dust removal can significantly improve the heat dissipation effect of the charging pile in actual application, ensuring that the equipment can operate stably in various environments.

[0033] The upper end of the threaded screw 41 is fixedly connected to a first fan guide blade 42 .

[0034] Further, specifically, with reference to Figure 5 As shown, at least two first air duct fins 42 are fixedly connected to the outer walls of the two threaded screws 41, and the two first air duct fins 42 are symmetrically arranged about the vertical center line of the positioning frame 21. The purpose of such arrangement is to allow the two threaded screws 41 to rotate and drive the heat dissipation range of the cooling fan 33 to move and change, while allowing the first air duct fins 42 to rotate synchronously in the inner cavity of the positioning frame 21, so as to blow the heat dissipation air in the inner cavity of the positioning frame 21 into the inner cavity of the charging pile body 101 through the air guide groove 23 for circulation, thereby improving the overall ventilation effect, ensuring the smooth circulation of air inside and outside the charging pile body 101, and further improving the heat dissipation effect.

[0035] Furthermore, one end of the threaded screw 41 extending out of the top of the positioning frame 21 is fixed with a first transmission gear 43, and a second transmission gear 44 is installed on the top of the charging pile body 101. The first transmission gear 43 and the second transmission gear 44 are connected by a first transmission belt 46, and a second fan blade 45 is fixed to one side of the second transmission gear 44.

[0036] Specifically, one end of the two threaded screws 41 extending out of the positioning frame 21 is fixedly mounted with a first transmission gear 43, and the inner cavity of the charging pile body 101 is rotatably mounted with a second transmission gear 44. The outer walls of the first transmission gear 43 and the second transmission gear 44 are meshed with a first transmission belt 46, and one side of the second transmission gear 44 is fixedly connected to a second fan fin 45;

[0037] The purpose of this arrangement is that when the threaded screw 41 rotates, the first transmission gear 43, the first transmission belt 46 and the second transmission gear 44 can synchronously drive the second fan blades 45 to rotate in the inner cavity of the charging pile body 101, so that the second fan blades 45 can again assist in blowing the cold air flowing into the inner cavity of the charging pile body 101 onto the cooling pipe 26, increasing the contact range between the cold air and the cooling pipe 26, thereby enhancing the heat dissipation effect of the coolant, achieving effective heat dissipation inside the charging pile body 101, maintaining the overall stable operation of the main body 1, and effectively improving the cooling efficiency of the coolant when circulating in the cooling pipe 26 and the liquid cooling circulation component 24, ensuring that the internal components of the main body 1 maintain a suitable working temperature, and extending the service life of the main body 1.

[0038] In specific implementation, the present invention installs a liquid-cooled heat dissipation mechanism 2 on one side of the charging pile body 101, and introduces coolant into the heat dissipation components through the liquid-cooled circulation component 24 and the cooling pipe 26 to flow around the heat dissipation components, absorb and take away heat, and ensure uniform heat dissipation; and by combining the setting of the heat dissipation fan 33 and the air guide cover 32, the outside air is introduced into the positioning frame 21 and the charging pile body 101 through the heat dissipation fan 33, and discharged after exchanging with heat. At the same time, the ventilation hole design on the air guide cover 32 ensures smooth air circulation and further improves the heat dissipation effect; at the same time, by setting the air-cooled heat dissipation mechanism 3 and the liquid-cooled heat dissipation mechanism 2, and providing the first dust removal scraper 36 and the second dust removal scraper 37 therein, when the heat dissipation fan 33 is operating, the first dust removal scraper 36 and the second dust removal scraper 37 simultaneously remove dust on the air guide cover 32 and the hollow plate 22 to prevent dust from clogging the heat dissipation channel and keep the air flow channel unobstructed.

[0039] Afterwards, by combining the sliding positioning hollow tube 31 and the linked threaded screw 41, the dust removal scraper 37 and the cooling fan 33 can move and rotate synchronously, ensuring the dynamic adjustment of the heat dissipation range and the dust removal effect, and improving the overall heat dissipation and dust prevention effects. In addition, combined with the setting of the threaded screw 41 and the first transmission gear 43 and the second transmission gear 44, the first fan guide blades 42 and the second fan guide blades 45 are driven to rotate through linkage, and the cold air is guided to the inside of the cooling pipe 26 and the charging pile body 101, thereby enhancing the heat dissipation effect of the coolant and further improving the heat dissipation efficiency.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
