Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a new energy vehicle charging pile with a heat dissipation and dust prevention structure. Background Technology

[0002] With the continuous development of technology and the rapid progress of society, the application of new energy vehicles is becoming increasingly common. New energy vehicles need to be charged to replenish their energy during use, thus requiring charging stations. The function of a new energy electric vehicle charging station is similar to that of a gas pump at a gas station; it can be fixed to the ground or a wall and is typically installed in public buildings such as charging stations, shopping malls, public parking lots, and residential parking lots.

[0003] Charging stations generally offer two charging methods: regular charging and fast charging. With the availability of advanced, environmentally friendly, economical, and reliable technologies and products, and the vigorous promotion of new energy vehicles, these vehicles are gaining increasing popularity. Therefore, there is a greater need for charging stations to serve new energy vehicles.

[0004] For example, Chinese Patent Publication No. CN216580146U describes a new energy vehicle charging pile cable that is easy to fix. The cable includes a new energy vehicle charging pile body. A top plate is bolted to the right side surface of the charging pile body. Support plates are symmetrically arranged near the left and right sides of the bottom of the top plate. A winding mechanism is provided between the two support plates. The winding mechanism includes a winding roller. A rotating rod is bolted to the right side of the winding roller. A cable is wound around the outer circumference of the winding roller. A limiting mechanism is provided on the right side of the winding roller. One end of the rotating rod passes through the right side of the support plate away from the charging pile body. A turntable is connected to the surface of the device. A handle is provided on the right side of the turntable, and the handle is rotatably connected to the turntable. One end of the cable passes through the left side of the support plate near the charging pile body and is connected to the charging pile body. The other end of the cable is connected to a charging gun. A U-shaped gun holder is fixedly connected to the left side of the support plate near the charging pile body by bolts. The left end of the charging gun is inserted into the U-shaped gun holder for easy fixing of the charging pile cable. By setting a winding mechanism and a limiting mechanism, the device can effectively wind and fix the cable, making it more convenient for users to use.

[0005] In existing technology references, the cable can be wound up by manually turning the handle to rotate the turntable. However, this design makes it inconvenient to automatically retract the cable. After charging is completed, users often drive on their way without remembering to retract the cable, resulting in the cable being scattered around the charging station. This makes it easy for the next driver to run over the cable, which can damage the cable over time and affect its lifespan. Summary of the Invention

[0006] To solve the above technical problems, the present invention is implemented through the following technical solution:

[0007] A new energy vehicle charging pile with a heat dissipation and dust prevention structure includes:

[0008] The cabinet, along with a camera mounted on top of the cabinet surface, allows for real-time monitoring of the surrounding environment, assisting in security monitoring of the equipment. Combined with an automated cable management structure, it is perfectly suited for unattended public charging scenarios such as public parking lots, highway service areas, and residential parks, effectively reducing manual operation and maintenance costs and improving user convenience for charging. A controller is fixedly installed on the top of the cabinet's interior, while heat dissipation and dust prevention components are installed on the outer sides of the cabinet. A protective mechanism is installed at the bottom of the cabinet.

[0009] The charging mechanism includes a charging host and a gun holder. The charging host is fixedly installed in the middle of the bottom of the cabinet cavity. The gun holder is detachably fixedly installed on the outer side. A charging gun is installed inside the gun holder. The tail of the charging gun is electrically connected to the charging host via a charging cable. A retractable assembly is installed on the top of the cabinet surface near the charging cable.

[0010] The take-up and take-down assembly includes a rotating connector, a winding reel, and a cable threading sleeve. The rotating connector is fixedly installed on the top side of the outer side of the cabinet. The winding reel is rotatably mounted on the inner wall of the cabinet near the top via a bracket. The cable threading sleeve is fitted over the middle of the charging cable. A servo motor is fixedly installed on the bracket outside the winding reel. A metal wire is wound around the middle of the outer side of the winding reel. A swing support arm is fixedly installed at the rotating end of the top of the rotating connector. The metal wire passes through the center of the rotating connector and the center of the swing support arm, and extends to the outside of the swing support arm. The charging gun is fixedly installed on the top of the outer circular surface of the cable sleeve. A flexible protective ring is fixedly connected to the inner wall of the cable sleeve. Through the electrical linkage between the camera, the gun holder and the controller, the camera can collect information about surrounding vehicles in real time and transmit the information to the controller in the form of electrical signals. The controller receives and processes the information. When a vehicle is parked in front of the cabinet and the charging gun is separated from the gun holder, the controller controls the servo motor to drive the winding wheel to rotate according to the preset program. The metal wire is automatically unloaded and the charging cable is lowered. With the connection of the charging cable, it is easier for the charging gun to be plugged into the vehicle that is charging. The whole process does not require manual operation and has a high degree of automation.

[0011] Preferably, the protective mechanism is used to support and elevate the cabinet and to provide anti-collision protection for the cabinet and its internal electrical components;

[0012] The protective mechanism includes a support frame and a rectangular opening. The support frame is detachably and fixedly installed at the bottom of the cabinet. The rectangular opening is located in the middle of the surface of the support frame. A right-angled baffle is slidably installed on the surface of the support frame through the rectangular opening. The bottom end of the right-angled baffle passes through the rectangular opening and extends into the interior of the support frame. A connecting guide post is detachably and fixedly installed inside the support frame. An electric telescopic rod is fixedly installed at the top of the inner cavity of the right-angled baffle. A wedge-shaped push tooth is fixedly connected to the telescopic end of the electric telescopic rod. A roller is rolled on the bottom of the outer side of the right-angled baffle, near the inclined surface of the wedge-shaped push tooth. An arc-shaped limiting tooth is fixedly installed at the top of the inclined surface of the outer side of the wedge-shaped push tooth.

[0013] The support frame elevates the entire cabinet, effectively preventing outdoor water accumulation and ground moisture from directly eroding the bottom of the cabinet. This prevents electrical components inside the cabinet from getting damp, short-circuiting, or corroding. It is suitable for complex installation scenarios such as outdoor open-air and low-lying areas. At the same time, the elevated cabinet reduces the contact area with the end of the vehicle, thus reducing the risk of vehicles scratching the cabinet and protecting the equipment inside.

[0014] Preferably, the right-angled baffle is slidably installed between itself and the connecting guide post, the connecting guide post is installed vertically, there are two connecting guide posts, and the two connecting guide posts are symmetrically installed along the central axis of the right-angled baffle, the electric telescopic rod is installed horizontally, there are two electric telescopic rods, and the two electric telescopic rods are symmetrically installed along the central axis of the right-angled baffle.

[0015] Utilizing an electrical connection between the electric telescopic rod and the controller, when the camera detects a vehicle approaching the cabinet, the controller activates the electric telescopic rod. The retraction of the telescopic rod's extension end applies a pulling force to the wedge-shaped pusher teeth. The inclined surface of the wedge-shaped pusher teeth applies an upward pushing force to the rollers, which in turn applies a lifting force to the right-angled baffle. The right-angled baffle moves upward to shield the front of the cabinet for protection. Combined with the limiting and locking structure of the rollers and arc-shaped limiting teeth, it can resist external vehicle scratches and object impacts, preventing cabinet deformation and damage to internal components. This enhances the charging pile's impact resistance and outdoor protection level. The structure boasts strong stability, and the symmetrically arranged connecting guide columns, electric telescopic rod, and roller structure ensures smooth baffle lifting and even force distribution, further improving the operational reliability of the protective mechanism.

[0016] Preferably, there are two wedge-shaped pushing teeth, and the two wedge-shaped pushing teeth are symmetrically installed along the central axis of the right-angled baffle. There are two rollers, and the two rollers are symmetrically installed along the central axis of the right-angled baffle. The outer circular surface of the rollers is in contact with the inclined surface of the wedge-shaped pushing teeth.

[0017] Preferably, the camera and the controller are electrically connected. The controller is used to capture information about vehicles near the cabinet and transmit the captured information to the controller in the form of an electrical signal. The charging gun base is electrically connected to the controller. When the charging gun is separated from the charging gun base, if a vehicle needs to be charged, the charging gun base will transmit the disconnection information to the controller in the form of an electrical signal. The controller controls the servo motor, and drives the winding wheel to rotate through the output end of the servo motor to automatically unwind the metal wire, and vice versa to automatically rewind the metal wire.

[0018] Once the vehicle is fully charged, the charging gun is reconnected to the gun holder. The gun holder sends a reset signal to the controller, which then controls the servo motor again. The output of the servo motor drives the winding wheel to rotate in the opposite direction, winding the metal wire. With the connection of the threading sleeve, the middle of the charging cable is lifted, preventing the charging cable from falling to the ground. This reduces the risk of subsequent vehicles running over the charging cable and extends its lifespan.

[0019] Preferably, the central shaft of the winding reel is fixedly installed to the output end of the servo motor via a coupling, the servo motor is electrically connected to the controller, there are two winding reels, and the two winding reels are symmetrically installed along the center of the cabinet.

[0020] The charging cable passes through the center of the cable threading sleeve, making it easy to lift and lower the sleeve using the metal wire. The inner wall of the cable threading sleeve is equipped with a flexible protective ring made of rubber, which can flexibly wrap and protect the outer wall of the charging cable, effectively preventing friction, wear, bending and breakage during cable winding and unwinding. In addition, the contact between the flexible protective ring and the outer wall of the charging cable can increase the friction, so that the charging cable will not slip off easily.

[0021] Preferably, the flexible protective rings are evenly distributed on the inner wall of the threading sleeve, and the flexible protective rings are made of rubber.

[0022] Preferably, the heat dissipation and dust prevention component includes a housing, which is fixedly installed on the outside of the cabinet and near the rotating connector. The housing extends through the cabinet and into its interior. A cover plate is fixedly installed at one end of the housing extending into the cabinet by screws. Ventilation holes are provided on the surface of the cover plate. A mesh is fitted onto the end of the housing away from the cover plate. A dustproof net is fixedly connected to the inside of the housing near the mesh. A driver is detachably fixedly installed in the middle of the inner cavity of the housing. A blade is fixedly connected to the output end of the driver. An elastic brush is fixedly connected to the edge of the blade surface. The dustproof net isolates the inner cavity of the housing, allowing external dust to enter the housing and be filtered out by the dustproof net, reducing dust and debris entering the cabinet and effectively preventing dust. At the same time, the driver drives the blade to rotate at high speed, which can form a directional blowing, blowing the air inside the cabinet outward, quickly dissipating the high temperature heat generated by the charging host, controller and other core working components inside the cabinet. This effectively solves the problems of poor heat dissipation, high temperature overload of components and performance degradation in traditional enclosed charging piles, ensuring continuous and efficient operation of the equipment.

[0023] Preferably, the outer frame of the grid is fixedly installed between the grid and the housing by screws, and there are two housings, which are symmetrically installed along the center of the cabinet.

[0024] As the blades rotate rapidly, the evenly distributed elastic brushes along the blade edges rotate synchronously, continuously and dynamically cleaning the surface of the dustproof net. This prevents the airflow from blowing the dust and debris swept down by the elastic brushes outwards, thus achieving electrical linkage between the dustproof net, the charging gun base, and the controller. The camera can collect information about surrounding vehicles in real time and transmit the information to the controller in the form of electrical signals. The controller receives and processes the information. When a vehicle stops in front of the cabinet and the charging gun is separated from the base, the controller controls the servo motor to drive the winding reel to rotate based on a preset program. The metal wire is automatically unwound, and the charging cable is lowered. With the charging cable connected, it is easy for the charging gun to connect with the vehicle being charged. The entire process requires no manual operation and has a high degree of automation.

[0025] 2. After the vehicle is fully charged, the charging gun is reconnected to the gun holder. The gun holder sends a reset signal to the controller, which then controls the servo motor again. The output of the servo motor drives the winding wheel to rotate in the opposite direction, winding the metal wire. With the connection of the threading sleeve, the middle of the charging cable is lifted, preventing the charging cable from falling to the ground. This makes it less likely for subsequent vehicles to run over the charging cable, thus extending the service life of the charging cable.

[0026] Third, the charging cable passes through the center of the cable threading sleeve, making it easy to lift and lower the sleeve with the metal wire. At the same time, the inner wall of the cable threading sleeve is equipped with a flexible protective ring made of rubber. The flexible protective ring can flexibly wrap and protect the outer wall of the charging cable, effectively preventing friction, wear, bending and breakage during the cable winding and unwinding process. In addition, the contact between the flexible protective ring and the outer wall of the charging cable can increase the friction, so that the charging cable will not slip off at will.

[0027] Fourth, the dustproof net isolates the inner cavity of the housing, allowing external dust to enter the housing and be filtered out, reducing the amount of dust and debris entering the cabinet and effectively preventing dust. At the same time, the driver drives the blades to rotate at high speed, creating a directional blowing effect. The air inside the cabinet is blown outward, quickly dissipating the high temperature heat generated by the charging host, controller, and other core components inside the cabinet. This effectively solves the problems of poor heat dissipation, high temperature overload of components, and performance degradation in traditional enclosed charging piles, ensuring continuous and efficient operation of the equipment.

[0028] 5. When the blades rotate rapidly, the evenly distributed elastic brushes on the blade edges rotate synchronously, continuously and dynamically cleaning the surface of the dustproof net. This prevents the airflow from blowing the dust and debris swept down by the elastic brushes outwards, thus elevating the entire cabinet. This effectively prevents outdoor water accumulation and ground moisture from directly eroding the bottom of the cabinet, preventing electrical components inside the cabinet from getting damp, short-circuiting, or corroding. It is suitable for complex installation scenarios such as outdoor open-air and low-lying areas. At the same time, the elevated cabinet reduces the contact area with the end of the vehicle, thus reducing the risk of vehicles scratching the cabinet and protecting the equipment inside.

[0029] 7. The inclined surface of the wedge-shaped pusher tooth applies an upward pushing force to the roller, which can apply a lifting force to the right-angled baffle. The right-angled baffle moves upward to block the front of the cabinet for protection. In conjunction with the limiting and locking structure of the roller and the arc-shaped limiting tooth, it can resist the scratches of external vehicles and the impact of external objects, avoid the deformation of the cabinet and the loosening and damage of internal components, improve the impact resistance and outdoor protection level of the charging pile, and has strong structural stability. The symmetrically arranged connecting guide column, electric telescopic rod and roller structure ensure that the baffle rises and falls smoothly and the force is evenly distributed, further improving the operational reliability of the protection mechanism.

[0040] Example 1, see Figures 1-6 A technical solution is provided:

[0041] A new energy vehicle charging pile with a heat dissipation and dust prevention structure includes:

[0042] The cabinet 1, and the camera 2 located on the top surface of the cabinet 1, the controller 3 fixedly installed on the top of the inner cavity of the cabinet 1, the heat dissipation and dust prevention components 4 installed on the outer side of the cabinet 1, and the protective mechanism 5 installed at the bottom of the cabinet 1.

[0043] The charging mechanism 6 includes a charging host 61 and a gun holder 62. The charging host 61 is fixedly installed in the middle of the bottom of the inner cavity of the cabinet 1. The gun holder 62 is detachably fixedly installed on the outer side. A charging gun 64 is installed inside the gun holder 62. The tail of the charging gun 64 is electrically connected to the charging host 61 via a charging cable 63. A retractable assembly 65 is installed on the top of the surface of the cabinet 1 near the charging cable 63.

[0044] The camera 2 is electrically connected to the controller 3. The camera 2 collects image information of vehicles around the cabinet 1 and transmits it to the controller 3. The gun base 62 is electrically connected to the controller 3.

[0045] The take-up and take-down assembly 65 includes a rotating connector 651, a winding reel 652, and a cable threading sleeve 653. The rotating connector 651 is fixedly installed on the top side of the outer side of the cabinet 1. The winding reel 652 is rotatably mounted on the inner wall of the cabinet 1 near the top via a bracket. The cable threading sleeve 653 is fitted over the middle of the charging cable 63. A servo motor 654 is fixedly installed on the bracket outside the winding reel 652. A metal wire 655 is wound around the middle of the outer side of the winding reel 652. A swing support arm 656 is fixedly installed on the rotating end of the top of the rotating connector 651. The metal wire 655 passes through the center of the rotating connector 651 and the center of the swing support arm 656, and extends to the outside of the swing support arm 656. One end of the charging gun 64 is fixedly installed on the top of the outer circular surface of the cable threading sleeve 653. A flexible protective ring 657 is fixedly connected to the inner wall of the cable threading sleeve 653. The camera 2 and the gun holder 62 are electrically linked with the controller 3. The camera 2 can collect information about surrounding vehicles in real time and transmit the information to the controller 3 in the form of electrical signals. The controller 3 receives and processes the information. When a vehicle stops in front of the cabinet 1 and the charging gun 64 is separated from the gun holder 62, the controller 3 controls the servo motor 654 to drive the winding wheel 652 to rotate according to the preset program. The metal wire 655 is automatically unloaded and the charging cable 63 is lowered. With the connection of the charging cable 63, it is easier for the charging gun 64 to be plugged into the vehicle that is being charged. The whole process does not require manual operation and has a high degree of automation.

[0046] When the charging gun 64 separates from the gun holder 62 and the vehicle is ready to charge, the gun holder 62 sends a separation signal to the controller 3. The controller 3 controls the servo motor 654 to drive the winding wheel 652 to rotate, and the metal wire 655 is automatically unloaded. When the charging gun 64 is reset and plugged into the gun holder 62, the servo motor 654 drives the winding wheel 652 to wind up the metal wire 655.

[0047] The central shaft of the winding reel 652 is fixedly installed to the output end of the servo motor 654 via a coupling. The servo motor 654 is electrically connected to the controller 3. There are two winding reels 652, and the two winding reels 652 are symmetrically installed along the center of the cabinet 1. After the vehicle is charged, the charging gun 64 is re-inserted into the gun holder 62. The gun holder 62 sends a reset signal to the controller 3. The controller 3 controls the servo motor 654 again, and drives the winding reel 652 to rotate in the opposite direction through the output end of the servo motor 654, so as to wind the metal wire 655. With the connection of the wire threading sleeve 653, the middle part of the charging cable 63 is lifted to prevent the charging cable 63 from falling to the ground. Subsequent vehicles that need to be charged are less likely to run over the charging cable 63, thus extending the service life of the charging cable 63.

[0048] Flexible protective rings 657 are evenly distributed on the inner wall of the cable threading sleeve 653. The flexible protective rings 657 are made of rubber. The charging cable 63 passes through the center of the cable threading sleeve 653, which allows the metal wire 655 to apply an upward pulling force to the cable threading sleeve 653, so that the charging cable 63 can be lifted and lowered. At the same time, the flexible protective rings 657 made of rubber on the inner wall of the cable threading sleeve 653 can flexibly wrap and protect the outer wall of the charging cable 63, effectively preventing friction wear, bending and breakage during cable winding and unwinding. In addition, the contact between the flexible protective rings 657 and the outer wall of the charging cable 63 can increase the friction, so that the charging cable 63 will not slip off easily.

[0049] Example 2, based on Example 1, see [link / reference] Figures 1 to 7 A technical solution is provided:

[0050] The protective mechanism 5 is used to support and elevate the cabinet 1 and to provide anti-collision protection for the cabinet 1 and its internal electrical components;

[0051] The protective mechanism 5 includes a support frame 51 and a rectangular opening 52. The support frame 51 is detachably and fixedly installed at the bottom of the cabinet 1. The rectangular opening 52 is located in the middle of the surface of the support frame 51. A right-angled baffle 53 is slidably installed on the surface of the support frame 51 through the rectangular opening 52. The bottom end of the right-angled baffle 53 passes through the rectangular opening 52 and extends into the interior of the support frame 51. A connecting guide post 54 is detachably and fixedly installed inside the support frame 51. An electric telescopic rod 55 is fixedly installed at the top of the inner cavity of the right-angled baffle 53. The telescopic end of the electric telescopic rod 55 is fixedly connected to a wedge-shaped pusher. The moving tooth 57 and the bottom of the right-angled baffle 53 are rollingly installed with a roller 56 near the inclined surface of the wedge-shaped pushing tooth 57. The top of the inclined surface of the wedge-shaped pushing tooth 57 is fixedly installed with an arc-shaped limiting tooth 58. The support frame 51 raises the entire cabinet 1, effectively preventing outdoor water accumulation and ground moisture from directly eroding the bottom of the cabinet 1, preventing the electrical components inside the cabinet 1 from getting damp, short-circuiting, or corroding. It is suitable for complex installation scenarios such as outdoor open-air and low-lying areas. At the same time, the raised cabinet 1 can reduce the contact area with the end of the vehicle, thereby reducing the scraping of the cabinet 1 by the vehicle and protecting the equipment inside the cabinet 1.

[0052] The right-angled baffle 53 is slidably installed between itself and the connecting guide post 54. The connecting guide post 54 is installed vertically. There are two connecting guide posts 54, and the two connecting guide posts 54 are symmetrically installed along the central axis of the right-angled baffle 53. The electric telescopic rod 55 is installed horizontally. There are two electric telescopic rods 55, and the two electric telescopic rods 55 are symmetrically installed along the central axis of the right-angled baffle 53.

[0053] By utilizing the electrical connection between the electric telescopic rod 55 and the controller 3, when the camera 2 captures a vehicle approaching the cabinet 1, the controller 3 controls the electric telescopic rod 55. The retraction of the telescopic end of the electric telescopic rod 55 applies a pulling force to the wedge-shaped push tooth 57. The inclined surface of the wedge-shaped push tooth 57 applies an upward pushing force to the roller 56, which applies a lifting force to the right-angled baffle 53. The right-angled baffle 53 moves upward to block the front of the cabinet 1 for protection. In conjunction with the limiting and locking structure of the roller 56 and the arc-shaped limiting tooth 58, it can resist external vehicle scratches and impacts from foreign objects, prevent the cabinet 1 from deforming, and prevent internal components from loosening and being damaged. It improves the impact resistance and outdoor protection level of the charging pile. The structure has strong stability, and the symmetrical arrangement of the connecting guide column 54, electric telescopic rod 55, and roller 56 ensures that the baffle rises and falls smoothly and the force is evenly distributed, further improving the operational reliability of the protection mechanism.

[0054] There are two wedge-shaped push teeth 57, and the two wedge-shaped push teeth 57 are symmetrically installed along the central axis of the right-angled baffle 53. There are two rollers 56, and the two rollers 56 are symmetrically installed along the central axis of the right-angled baffle 53. The outer circular surface of the rollers 56 is in contact with the inclined surface of the wedge-shaped push teeth 57.

[0055] Example 3, based on Examples 1 and 2, see [reference] Figures 1 to 9 A technical solution is provided:

[0056] The heat dissipation and dust prevention component 4 includes a housing 41, which is fixedly installed on the outside of the cabinet 1 and near the rotating connector 651. The housing 41 penetrates the cabinet 1 and extends into its interior. A cover plate 42 is fixedly installed at one end of the housing 41 that extends into the cabinet 1 by screws. Ventilation holes 43 are provided on the surface of the cover plate 42. A mesh 44 is fitted onto the end of the housing 41 away from the cover plate 42. A dustproof mesh 45 is fixedly connected inside the housing 41 and near the mesh 44. A driver 46 is detachably fixedly installed in the middle of the inner cavity of the housing 41. A blade 47 is fixedly connected to the output end of the driver 46. An elastic brush 48 is fixedly connected to the edge of the surface of the blade 47.

[0057] The dustproof net 45 isolates the inner cavity of the housing 41, allowing external dust to enter the housing 41 and be filtered out by the dustproof net 45, reducing the amount of dust and debris entering the cabinet 1 and effectively preventing dust. At the same time, the driver 46 drives the blades 47 to rotate at high speed, which can form a directional blowing, blowing the air inside the cabinet 1 outward, quickly dissipating the high temperature heat generated by the charging host 61, controller 3 and other core working components inside the cabinet 1, effectively solving the problems of poor heat dissipation, high temperature overload of components and performance degradation in traditional enclosed charging piles, and ensuring continuous and efficient operation of the equipment.

[0058] The outer frame of the grid 44 is fixedly installed to the housing 41 with screws. There are two housings 41, and the two housings 41 are symmetrically installed along the center of the cabinet 1. When the blades 47 rotate rapidly, the elastic brushes 48 evenly distributed on the edge of the blades 47 can rotate synchronously to continuously and dynamically clean the surface of the dustproof net 45. This prevents dust from clogging the mesh holes after long-term use of the dustproof net 45, which would lead to heat dissipation failure. In addition, the airflow blown by the rotating blades 47 causes the airflow to blow the dust and debris swept down by the elastic brushes 48 to the outside, realizing the self-cleaning function of the dustproof net 45. There is no need for frequent manual disassembly and cleaning, which greatly reduces the equipment maintenance cost and ensures long-term stable heat dissipation and dust prevention effects.

[0059] Elastic brushes 48 are evenly distributed on the edge of the blade 47 surface, and the end of the elastic brushes 48 away from the blade 47 is attached to the surface of the dustproof net 45.

[0060] When in use, the entire cabinet 1 is raised by the support frame 51, which effectively avoids outdoor water accumulation and ground moisture from directly eroding the bottom of the cabinet 1, preventing the electrical components inside the cabinet 1 from getting damp, short-circuiting, or corroding and being damaged. It is suitable for complex installation scenarios such as outdoor open-air and low-lying areas. At the same time, the raised cabinet 1 can reduce the contact area with the end of the vehicle, which can reduce the vehicle's scratches on the cabinet 1, thereby protecting the equipment inside the cabinet 1.

[0061] Furthermore, by utilizing the electrical connection between the electric telescopic rod 55 and the controller 3, when the camera 2 captures a vehicle approaching the cabinet 1, the controller 3 controls the electric telescopic rod 55. The retraction of the telescopic end of the electric telescopic rod 55 applies a pulling force to the wedge-shaped push tooth 57. The inclined surface of the wedge-shaped push tooth 57 applies an upward pushing force to the roller 56, which applies a lifting force to the right-angle baffle 53. The right-angle baffle 53 moves upward to block the front of the cabinet 1 for protection. In conjunction with the limiting and locking structure of the roller 56 and the arc-shaped limiting tooth 58, it can resist external vehicle scratches and external object impacts, and prevent the cabinet 1 from deforming and the internal components from loosening and being damaged.

[0062] Furthermore, through the electrical linkage between camera 2, gun base 62 and controller 3, camera 2 can collect surrounding vehicle information in real time and transmit the information to controller 3 in the form of electrical signals. Controller 3 receives and processes the information. When a vehicle stops in front of cabinet 1 and the charging gun 64 is separated from the gun base 62, based on the preset program, controller 3 controls servo motor 654 to drive winding wheel 652 to rotate, metal wire 655 automatically unwinds, and charging cable 63 is laid down. With the connection of charging cable 63, it is easier for charging gun 64 to be plugged in and cooperate with the vehicle being charged. The whole process does not require manual operation and has a high degree of automation.

[0063] After the vehicle is fully charged, the charging gun 64 is reconnected to the gun holder 62. The gun holder 62 sends a reset signal to the controller 3. The controller 3 then controls the servo motor 654 again. The output of the servo motor 654 drives the winding wheel 652 to rotate in the opposite direction, winding the metal wire 655. With the connection of the threading sleeve 653, the middle of the charging cable 63 is lifted, preventing the charging cable 63 from falling to the ground. This makes it less likely for subsequent vehicles to run over the charging cable 63, thus extending the service life of the charging cable 63.

[0064] Furthermore, the dustproof net 45 isolates the inner cavity of the housing 41, so that when external dust enters the housing 41, the dust will be filtered out by the dustproof net 45, reducing the amount of dust and debris entering the cabinet 1 and effectively preventing dust. At the same time, the driver 46 drives the blades 47 to rotate at high speed, which can form a directional blowing, and the air inside the cabinet 1 is blown outward, quickly dissipating the high temperature heat generated by the core working components such as the charging host 61 and the controller 3 inside the cabinet 1.

[0065] Meanwhile, the elastic brushes 48 evenly distributed along the edge of the blades 47 can rotate synchronously to continuously and dynamically clean the surface of the dustproof net 45, preventing dust from clogging the mesh after long-term use and causing heat dissipation failure. Furthermore, the airflow generated by the rotating blades 47 blows the dust and debris swept down by the elastic brushes 48 outwards, achieving the self-cleaning function of the dustproof net 45. This eliminates the need for frequent manual disassembly and cleaning, significantly reducing equipment maintenance costs and ensuring long-term stable heat dissipation and dust prevention effects.

[0066] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
