Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with efficient heat dissipation. Background Art

[0002] A new energy charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electrical energy to electric vehicles, enabling them to store enough electricity to support their operation.

[0003] The heat dissipation of new energy charging piles is a key factor to ensure their stable operation and extend their service life. After searching, a Chinese patent with announcement number CN218228680U discloses a charging pile with uniform heat dissipation function, including a shell, an operating table is arranged on the outer wall of the shell, and the shell is also connected to a charging plug. A core component is arranged in the charging pile, and the core component is connected to the inner wall of the shell. The core component is electrically connected to the operating table and the charging plug respectively. A first ventilation window is opened at the upper end of the shell, and the first ventilation window is provided with a protective net. The peripheral edges of the protective net are connected to the outer wall of the shell. A supply fan is arranged below the protective net, and the supply fan is connected to the inner wall of the shell. A second ventilation window is opened at the lower end of the shell, and a protective frame is arranged outside the second ventilation window. An exhaust fan is arranged in the protective frame. A wire take-up assembly is arranged on the inner wall of the shell, and a plurality of wires are led out of the core component. The plurality of wires are evenly arranged in the wire take-up assembly. The scheme can improve the problem of low heat dissipation efficiency of electric vehicle charging piles in the prior art. However, the above scheme still has the following shortcomings when it is actually used.

[0004] During the use of the charging pile, dust in the external environment is easy to adhere to the dustproof net. The accumulation of dust will cause the dustproof net to be blocked. The accumulation of dust and the blockage of the dustproof net will hinder the heat dissipation of the internal electrical components of the charging pile. The charging pile will generate a certain amount of heat when working. If the heat cannot be dissipated in time, the internal temperature of the charging pile will cause the temperature to rise. Long-term high-temperature operation will not only reduce the working efficiency of the charging pile, but may also cause overheating failures and even lead to safety hazards such as fire.

[0016] As a preferred technical solution of the present invention, the flow limiting directions of the two one-way valves are opposite.

[0017] The present invention has the following beneficial effects: 1. During use, the air inside and outside the charging pile dissipates heat through convection, and the dustproof sleeve effectively blocks the invasion of external dust, ensuring the cleanliness of the inside of the charging pile. At the same time, the synchronous operation of the motor drives the rotation of the dustproof sleeve. This dynamic process not only enhances the dustproof effect, but also provides a basis for subsequent cleaning work. More importantly, through the cooperation of the bevel gear and the eccentric wheel, the vibration of the cleaning plate is driven, and the bristles on it can continuously brush the surface of the dustproof sleeve, effectively brushing off the attached dust, avoiding the clogging of the dustproof sleeve, thereby ensuring the continuous heat dissipation performance of the charging pile. Compared with the traditional fixed dustproof net structure, the combination of this rotatable dustproof sleeve and the vibrating cleaning plate not only improves the dustproof efficiency, but also realizes the automated cleaning process, ensuring the long-term stable operation of the charging pile; 2. The axial flow blades arranged on the suction piece perform the suction action when rotating, effectively extracting the air in the dust suction pipe connected to the dust suction cylinder. This design enables the dust suction ports on the two dust suction pipes to efficiently absorb the dust brushed off by the bristles, and then the dust is discharged into the dust collection box for collection through the operation of the suction piece. This whole process not only prevents the dust from falling into the charging pile, but also effectively prevents the dust from secondary contamination of the dustproof sleeve and the internal components of the charging pile, and also ensures the cleanliness and safety of the operating environment of the charging pile, further improving the heat dissipation performance and long-term reliability of the charging pile; 3. The air guide structure integrated in the dustproof sleeve, including the air guide cover and the air guide duct, as well as several guide plates in the air guide duct, together construct an S-shaped airflow channel. This design ensures that the air in the external environment can pass through an extended and tortuous path before entering the charging pile, which not only enhances the stability of the airflow, but also improves the heat dissipation efficiency. Furthermore, the cooling pipe fixed on the air guide duct cools the gas flowing inside the air guide duct by accumulating low-temperature coolant, effectively reducing the temperature of the gas entering the charging pile. Especially in the high temperature environment in summer, even if the air inside the charging pile is discharged and the hot air from the outside is replenished, it can be effectively cooled through this cooling mechanism, thereby avoiding the overheating problem of the charging pile caused by the high temperature environment. This comprehensive design not only ensures the heat dissipation performance of the charging pile, but also extends its service life and improves the stability and reliability of the overall operation; 4. An S-shaped airflow channel is created through the air guide pipe and several guide plates. This design not only optimizes the flow path of the airflow, but also significantly prolongs the flow time of the gas in the air guide pipe. Under the precise guidance of the guide plate, the gas is forced to move along a tortuous path. In this process, there is more contact time and heat exchange opportunities between the gas and the low-temperature cooling tube. This increased heat exchange time ensures that the cooling tube can give full play to its cooling effect; 5. The built-in circulating flow structure enables efficient recycling of the coolant. This structure ensures that the coolant circulates continuously between the cooling pipe and the refrigeration compressor. When the coolant flows through the refrigeration compressor, its temperature is significantly reduced, thereby ensuring that the cooling pipe is always filled with low-temperature coolant. This design not only improves the cooling efficiency of the cooling pipe for the gas, but also ensures the long-term stability of the cooling effect. Through the circulating flow structure, the coolant can continuously obtain cold from the refrigeration compressor, and then effectively absorb and take away the heat of the gas in the air duct in the cooling pipe, thereby achieving continuous cooling of the gas entering the charging pile. This innovative design significantly enhances the thermal management capability of the charging pile, and can ensure the stability of the internal temperature of the charging pile even in extremely high temperature environments.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

The air inside and outside the charging pile shell 1 is convected through the heat dissipation port 2, and the dustproof sleeve facing the heat dissipation port 2 can prevent dust in the external environment from entering the interior of the charging pile shell 1, thereby playing a dustproof role; the opening 5 is opened in the middle position of one of the side panels 3; the mounting plate 6 is fixed inside the charging pile shell 1.

[0022] The charging pile also includes a rotating structure, which is arranged on the mounting plate 6, and the rotating structure includes: a motor 71, which is installed on the mounting plate 6; a drive shaft 72, which is fixed on the output shaft of the motor 71, and at least two bearing seats are fixed on the mounting plate 6, and the drive shaft 72 is rotatably installed on the two bearing seats; a rotating rod 73, which is fixed at the middle position of the side surface of one of the side plates 3; a transmission member 74, and the drive shaft 72 and the rotating rod 73 are connected by transmission via the transmission member 74.

[0023] The charging pile also includes a cleaning structure, which is arranged on the mounting plate 6, and the cleaning structure includes: a cleaning plate 81, which is arranged below the mounting plate 6, and the cleaning plate 81 is located directly above the dustproof mesh tube 4; a plurality of bristles 82, all of which are arranged on the bottom surface of the cleaning plate 81; a limiting opening 83, which is opened on the mounting plate 6; a limiting block 84, which is fixed on the top surface of the cleaning plate 81, and the limiting block 84 is slidably arranged in the limiting opening 83; a limiting plate 85, which is fixed on the top surface of the limiting block 84, and the bottom surface of the limiting plate 85 and the top surface of the mounting plate 6 are in contact with each other; a tension spring 86, one end of which is connected to the limiting plate 85, and the other end is connected to the mounting plate 6.

[0024] The charging pile also includes a vibration structure, which is arranged on the mounting plate 6, and the vibration structure includes: a fixing frame 101, which is fixed on the side of the mounting plate 6, and an assembly opening is opened on the fixing frame 101; a rotating shaft 102, which is rotatably installed in the assembly opening; an eccentric wheel 103, which is fixedly sleeved on the rotating shaft 102, and the eccentric wheel 103 is eccentrically arranged between the rotating shaft 102; two bevel gears 104, one of which is fixedly sleeved on the driving shaft 72, and the other bevel gear 104 is fixedly sleeved on the rotating shaft 102, and the two bevel gears 104 are meshed with each other; a push rod 105, which is fixed on the top surface of the limiting plate 85, and the end of the push rod 105 away from the limiting plate 85 is arranged opposite to the eccentric wheel 103.

[0025] When the charging pile housing 1 is running, the motor 71 runs synchronously, driving the drive shaft 72 to rotate. When the drive shaft 72 rotates, it can drive the rotating rod 73 to rotate through the transmission member 74, and the rotating rod 73 drives the corresponding mounting plate 6 to rotate, which causes the dust sleeve to rotate accordingly. In addition, when the drive shaft 72 rotates, it can also drive the rotating shaft 102 to rotate through two mutually meshing bevel gears 104, and the eccentric wheel 103 on the rotating shaft 102 will also rotate accordingly. The eccentric wheel 103 will continuously squeeze the push rod 105 during the rotation process. When the eccentric wheel 103 squeezes the push rod 105, the push rod 105 can drive the limit plate 85 to move. When the eccentric wheel 103 is separated from the push rod 105, the limit plate 85 will be reset under the elastic force of the tension spring 86. Therefore, along with the rotation of the eccentric wheel 103, the limit plate 85 will produce a vibration effect, which makes the cleaning plate 81 vibrate continuously. During the vibration of the cleaning plate 81, the bristles 82 thereon can continuously brush the dustproof sleeve directly below the cleaning plate 81 and brush off the dust attached to the surface of the dustproof sleeve, thereby cleaning the dustproof sleeve.

[0026] The charging pile also includes an air guide structure, which is arranged inside the dust-proof mesh tube 4, and the air guide structure includes: an air guide cover 121, which is placed inside the dust-proof mesh tube 4, and the air guide cover 121 is provided with a curved surface that matches the dust-proof mesh tube 4; an air guide pipe 122, which is fixed on the air guide cover 121 and communicated with the air guide cover 121; a cooling pipe 123, which is fixedly sleeved on the air guide pipe 122, and coolant is accumulated inside the cooling pipe 123; a plurality of guide plates 124, which are all fixed inside the air guide pipe 122, each of the guide plates 124 is arranged at an angle, and the plurality of guide plates 124 and the air guide pipe 122 together form an S-shaped airflow channel.

[0027] When the air in the external environment enters the charging pile housing 1 through the heat dissipation port 2, the airflow will enter the air guide cover 121, and enter the air guide pipe 122 under the guidance of the air guide cover 121. The air guide pipe 122 is provided with a plurality of guide plates 124, and the plurality of guide plates 124 and the air guide pipe 122 together form an S-shaped airflow channel, through which the gas finally enters the charging pile housing 1. Further, a cooling pipe 123 is fixed on the air guide pipe 122, and a low-temperature coolant is accumulated in the cooling pipe 123, so that the cooling pipe 123 can cool the gas flowing inside the air guide pipe 122, thereby cooling the gas entering the charging pile housing 1. This design can ensure the heat dissipation performance of the charging pile housing 1. In summer, the ambient temperature around the charging pile housing 1 is very high. Even if the air inside the charging pile housing 1 is discharged, the hot air in the external environment will be supplemented to the inside of the charging pile housing 1. This gas cooling mechanism can effectively solve this problem.

[0028] A dust suction structure is provided on the mounting plate 6, and the dust suction structure includes: two dust suction pipes 111, which are respectively fixed on both sides of the mounting plate 6, and the two dust suction pipes 111 are connected by a U-shaped pipe; a plurality of dust suction ports 112 are respectively opened on the two dust suction pipes 111; a fixing rod 113, which is fixed on the mounting plate 6; a dust suction cylinder 114, which is fixed to the end of the fixing rod 113 away from the mounting plate 6, and both ends of the dust suction cylinder 114 are provided with through openings, and the driving shaft 72 passes through the two through openings; an air suction member 115, which is fixedly sleeved on the driving shaft 72, and the air suction member 115 is placed in the dust suction cylinder 114, and the air suction member 115 includes a sleeve and a plurality of axial flow blades, the sleeve is fixedly sleeved on the driving shaft 72, and the plurality of axial flow blades are fixed on the sleeve, and the plurality of axial flow blades are distributed in a circumferential array; a dust collecting box 116, which is installed on the side of the mounting plate 6 ; An air inlet pipe, one end of which is connected to the dust collection cylinder 114, and the other end is connected to one of the dust collection pipes 111; an air outlet pipe, one end of which is connected to the dust collection cylinder 114, and the other end is connected to the dust collection box 116. When the drive shaft 72 rotates, it can also drive the suction piece 115 to rotate. The suction piece 115 is provided with a plurality of axial flow blades, and the plurality of axial flow blades can perform a suction action when rotating. Therefore, when the suction piece 115 rotates, it can extract the air in the dust collection pipe 111 connected to the dust collection cylinder 114. In this case, the plurality of dust suction ports 112 on the two dust collection pipes 111 can absorb the dust brushed off by the bristles 82, and the dust is discharged into the dust collection box 116 by the suction piece 115, so as to collect the dust, prevent the dust from falling into the interior of the charging pile housing 1, and prevent the dust from causing secondary pollution to the dustproof sleeve.

[0029] A refrigeration compressor 13 is installed inside the charging pile housing 1, and a circulating flow structure is arranged on the mounting plate 6, which comprises: a connecting rod 141, which is fixed on the fixing frame 101; a mounting cylinder 142, which is fixed on the end of the connecting rod 141 away from the fixing frame 101, and a avoidance opening adapted to the rotating shaft 102 is opened on the bottom surface of the mounting cylinder 142, and the top end of the rotating shaft 102 extends to the inside of the mounting cylinder 142 through the avoidance opening; a rotating block 143, which is rotatably installed in the mounting cylinder 142, and the rotating block 143 is fixed on the top end of the rotating shaft 102; a moving block 144, which is slidably arranged in the mounting cylinder 142; a slide groove 145 , opened on the inner surface of the mounting tube 142; the slider 146, fixed on the moving block 144, the slider 146 slides in the slide groove 145; the capsule 147, one end of which is connected to the inner top surface of the mounting tube 142, and the other end is connected to the moving block 144; two mounting tubes 148, one end of which is connected to the capsule 147, the other end of one mounting tube 148 is connected to the cooling tube 123, and the other end of the other mounting tube 148 is connected to the refrigeration compressor 13, and the refrigeration compressor 13 and the cooling tube 123 are connected through the return pipe; two one-way valves 149 are respectively installed on the two mounting tubes 148. The limiting directions of the two one-way valves 149 are opposite, the purpose is to make the coolant circulate in the cooling tube 123 and the refrigeration compressor 13. When the coolant passes through the refrigeration compressor 13, the temperature of the coolant is reduced, thereby ensuring that there is always low-temperature coolant in the cooling tube 123. This design provides a guarantee for the cooling effect of the cooling tube 123 on the gas.

[0030] The specific working principle of the present invention is as follows: When the charging pile proposed by the present invention is in use, the air inside and outside the charging pile housing 1 is convected through the heat dissipation port 2, and the dustproof sleeve facing the heat dissipation port 2 can prevent dust in the external environment from entering the interior of the charging pile housing 1, thereby playing a dustproof role. In addition, when the charging pile housing 1 is in operation, the motor 71 operates synchronously, driving the drive shaft 72 to rotate. When the drive shaft 72 rotates, it can drive the rotating rod 73 to rotate through the transmission member 74, and the rotating rod 73 drives the corresponding mounting plate 6 to rotate, which causes the dustproof sleeve to rotate accordingly. In addition, when the drive shaft 72 rotates, it can also drive the rotating shaft 102 to rotate through two mutually meshing bevel gears 104, and the eccentric wheel 103 on the rotating shaft 102 will also rotate accordingly. The eccentric wheel 103 will continuously squeeze the push rod 105 during the rotation process. When the eccentric wheel 103 squeezes the push rod 105, the push rod 105 can drive the limit plate 85 to move. When the eccentric wheel 103 is separated from the push rod 105, the limit plate 85 will be reset under the elastic force of the tension spring 86. Therefore, along with the rotation of the eccentric wheel 103, the limit plate 85 will produce a vibration effect, which makes the cleaning plate 81 vibrate continuously. During the vibration of the cleaning plate 81, the bristles 82 on it can continuously brush the dustproof sleeve directly below the cleaning plate 81 and brush off the dust attached to the surface of the dustproof sleeve, thereby cleaning the dustproof sleeve. Based on the above process, the vibrating cleaning plate 81 can perform a comprehensive cleaning process on the rotating dustproof sleeve, which can prevent dust from clogging the dustproof sleeve, thereby ensuring the heat dissipation performance of the charging pile housing 1. The rotatable dustproof sleeve replaces the traditional fixed dustproof net structure. This dynamic process provides a basis for cleaning work. It is worth noting that the transmission member 74 adopts a belt drive transmission method, and the transmission member 74 reduces the rotation speed of the drive shaft 72, which enables the dustproof sleeve to rotate slowly, ensuring the cleaning effect of the cleaning plate 81 on the dustproof sleeve.

[0031] In addition, the driving shaft 72 can also drive the suction piece 115 to rotate when it rotates. The suction piece 115 is provided with a plurality of axial flow blades. The plurality of axial flow blades can perform a suction action when it rotates. Therefore, the suction piece 115 can extract the air in the dust suction pipe 111 connected to the dust suction cylinder 114 when it rotates. In this case, the plurality of dust suction ports 112 on the two dust suction pipes 111 can absorb the dust brushed off by the bristles 82, and the dust is discharged into the dust collecting box 116 by the suction piece 115, so as to collect the dust, prevent the dust from falling into the interior of the charging pile housing 1, and prevent the dust from causing secondary pollution to the dustproof sleeve.

[0032] The dustproof sleeve is also provided with an air guide structure for guiding airflow. When the air in the external environment enters the charging pile housing 1 through the heat dissipation port 2, the airflow will enter the air guide cover 121 and enter the air guide pipe 122 under the guidance of the air guide cover 121. The air guide pipe 122 is provided with a plurality of guide plates 124. The plurality of guide plates 124 and the air guide pipe 122 together form an S-shaped airflow channel. The gas passes through the airflow channel and finally enters the interior of the charging pile housing 1. Furthermore, a cooling pipe 123 is fixed on the air duct 122, and a low-temperature coolant is accumulated in the cooling pipe 123. Therefore, the cooling pipe 123 can cool down the gas flowing inside the air duct 122, thereby cooling down the gas entering the charging pile housing 1. This design can ensure the heat dissipation performance of the charging pile housing 1. In summer, the ambient temperature around the charging pile housing 1 is very high. Even if the air inside the charging pile housing 1 is discharged, the hot air in the external environment will be supplemented to the inside of the charging pile housing 1. This gas cooling mechanism can effectively solve this problem. It is worth noting that under the guiding effect of several guide plates 124, the gas can flow along an S-shaped path in the air duct 122, which can extend the flow time of the gas in the air duct 122, so that there is more heat exchange time between the gas and the low-temperature cooling pipe 123, and the cooling effect of the cooling pipe 123 on the gas is guaranteed.

[0033] A circulating flow structure for circulating coolant is also provided inside the charging pile housing 1, the purpose of which is to make the coolant circulate in the cooling pipe 123 and the refrigeration compressor 13. When the coolant passes through the refrigeration compressor 13, the temperature of the coolant is reduced, thereby ensuring that there is always low-temperature coolant in the cooling pipe 123. This design provides a guarantee for the cooling effect of the cooling pipe 123 on the gas. Specifically, the rotating shaft 102 can drive the rotating block 143 connected thereto to rotate while driving the eccentric wheel 103 to rotate. Since the rotating block 143 and the moving block 144 form a cylindrical structure together, the rotating block 143 and the moving block 144 are of the same size, and the opposite ends of the rotating block 143 and the moving block 144 are both provided with inclined surfaces, and the outer edges of the rotating block 143 and the moving block 144 are both in contact with the inner surface of the mounting tube 142, so during the rotation of the rotating block 143, its inclined surface portion can squeeze the inclined surface portion of the moving block 144. Under the limiting action of the slide groove 145 and the slider 146, the movable block 144 cannot rotate with the rotating block 143, so the movable block 144 moves under the squeezing action of the rotating block 143, and at the same time cooperates with the elasticity of the capsule 147 itself, so that the movable block 144 moves back and forth in the installation tube 142.

[0034] In this process, the capsule 147 is squeezed and stretched periodically. Furthermore, the flow limiting directions of the two one-way valves 149 are opposite, one of the one-way valves 149 restricts the liquid to only enter the capsule 147, and the other one-way valve 149 restricts the liquid to only flow out of the capsule 147. Therefore, when the capsule 147 is squeezed, the coolant in the capsule 147 will be pressed into the refrigeration compressor 13. When the capsule 147 recovers, the capsule 147 will perform an extraction action and draw the coolant in the cooling pipe 123 into it. Based on the above process, with the rotation of the shaft 102, the coolant will circulate between the cooling pipe 123, the capsule 147 and the refrigeration compressor 13, so that the refrigeration compressor 13 cools the coolant.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
