Description

Technical Field

[0001] The invention relates to the technical field of control boxes, in particular to a cluster type electric vehicle charging device control box. Background Art

[0002] As energy becomes increasingly scarce, electric vehicles have become the preferred choice for people to travel. As a result, the inconvenience of charging cars compared to refueling has become an increasingly important obstacle to the popularization of electric vehicles. Even DC fast charging is much slower than refueling, and it is impossible for the power supply system to set up fast charging ports everywhere. At present, we can only choose the dense AC slow charging mode and use the opportunity of electric vehicles stopping to charge. For the intelligent AC slow charging devices on the market, the output points basically use semiconductor output or relay output, without arc extinguishing protection devices, and the output points are prone to irreparable damage; if a motor-driven intelligent circuit breaker is installed in the cluster electric vehicle charging device control box, the volume will be very large, and the opening and closing speed is very slow, and the cost is still high.

[0003] The Chinese patent with publication number CN115206741A discloses a cluster type electric vehicle charging device control box, including: a control box body and a central processing unit, a switching power supply, a plurality of circuit breaker units, and a wireless communication unit arranged side by side in the control box body, wherein the central processing unit is electrically connected to the switching power supply, the plurality of circuit breaker units, and the wireless communication unit respectively, the incoming line end of the circuit breaker unit is connected to the power input main cable, the outgoing line end of the circuit breaker unit is connected to a plurality of charging gun cables, and a plurality of the charging gun cables are connected to a plurality of charging guns; each circuit breaker unit adopts a double combination electric permanent magnet composed of a magnetic line closed permanent magnet and an electromagnet The opening and closing mechanism does not generate mutual magnetic field interference between adjacent circuit breakers; when a circuit breaker needs to be opened and closed, only an extremely short DC pulse needs to be applied to the electromagnetic coil of the electromagnet of the corresponding circuit breaker, so that the opening and closing control of the relevant power line can be realized, the opening and closing is more sensitive, and it is less likely to cause false tripping, and the opening and closing reaction speed can be greatly improved. The tripping sensitivity and shock resistance are higher than those of the traditional mechanical tripping scheme. Moreover, the life of the mechanical tripper is only tens of thousands of times, while the service life of the scheme can reach millions of times, and the present invention does not require a motor drive mechanism, which is more convenient for remote intelligent control of the circuit breaker. Since the control box of the cluster electric vehicle charging device generates heat when in use, in order to achieve the effect of heat dissipation, a heat dissipation hole is often opened in the control box. However, since the environment in which the control box of the cluster electric vehicle charging device is used is outdoors, it may also be in a location with relatively large traffic flow, which leads to more dust and impurities in the surrounding environment. Although a filter can be set on the heat dissipation hole, the heat dissipation hole is in a state of being opened for a long time, and the external dust is also easy to accumulate inside the control box. The dust in the control box needs to be cleaned frequently, which increases the workload of the staff. Summary of the invention

[0004] The object of the present invention is to provide a cluster type electric vehicle charging device control box to solve the problems raised in the above background technology.

[0008] As a further improvement of the present invention, a cleaning assembly is provided on the rear side of the control box body, and the cleaning assembly includes a square opening, a connecting frame, a movable box and a brush plate. A square opening is opened on the rear side of the control box body, and a connecting frame passing through the square opening is fixedly installed on the rear side of the movable plate, a movable box is fixedly installed on the bottom of the connecting frame, and a brush plate is provided on the front side of the movable box.

[0011] As a further improvement of the present invention, the outer side of the moving wheel is tightly fitted to the rear side of the control box.

[0012] As a further improvement of the present invention, a collection box is fixedly installed at the lower rear side of the control box.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The control box of the cluster electric vehicle charging device is provided with a dust blocking component through the rear side of the circuit breaker unit. When the circuit breaker unit is in a closed state, the structure in the control box is not in use and can not generate heat. The heat dissipation holes on the control box are blocked by a movable plate, and the control box is in a sealed state, thereby preventing external dust from entering the control box, reducing the time for opening the heat dissipation holes, lengthening the cycle for cleaning the dust in the control box, and reducing the labor of the staff.

[0015] 3. The control box of the cluster-type electric vehicle charging device, when the mobile box moves, the moving wheel and the control box body are closely fitted and have friction, thereby driving the moving wheel and the connecting shaft to rotate, thereby driving the cam to rotate, and utilizing the shape characteristics of the cam to push the brush plate to move outward, so that the brush strips on the brush plate are moved out of the mobile box for cleaning the heat dissipation holes. When charging is not needed, the moving wheel moves in the opposite direction, thereby driving the brush plate to move toward the inside of the mobile box, so as to separate dust and impurities on the brush strips from the brush strips, and facilitate continuous use of the brush plate.

[0021] A dust blocking component 4 is arranged at the rear side of the circuit breaker unit 3. The dust blocking component 4 includes a limit plate 401 and a moving rod 404. The electromagnetic moving structure on the circuit breaker unit 3 is connected to the moving rod 404.

A dust blocking component 4 is provided on the rear side of the circuit breaker unit 3.

The heat dissipation holes 7 on the control box 1 are blocked by the movable plate 402, and the control box 1 is in a sealed state, thereby preventing external dust from entering the control box 1, reducing the opening time of the heat dissipation holes 7, lengthening the cycle of cleaning the dust in the control box 1, and reducing the labor of the staff. When the circuit breaker unit 3 is in the closed state, the movable rod 404 is driven to move backward, and the second magnet 410 is driven to move in the movable box 405, thereby pushing the first magnet 409 and the push plate 406 to move backward. Since the push plate 406 is connected to the movable plate 402 by the connecting rod 407, the movable plate 402 is driven to move, so that the connecting hole 403 is connected to the heat dissipation hole 7, which is convenient for opening the heat dissipation hole 7 on the control box 1 for heat dissipation.

[0022] In this embodiment, the magnetic poles of the second magnet 410 and the first magnet 409 that are close to each other are the same.

[0023] In this embodiment, a plurality of evenly distributed circuit breaker units 3 are provided in the control box 1, and a movable rod 404 is connected to the rear side of each circuit breaker unit 3, so that when one circuit breaker unit 3 is in use, the heat dissipation holes 7 on the control box 1 can be opened to dissipate heat in the entire control box 1.

[0024] In this embodiment, a cleaning assembly 5 is provided at the rear side of the control box 1, and the cleaning assembly 5 includes a square opening 501, a connecting frame 502, a moving box 503 and a brush plate 504. The square opening 501 is provided at the rear side of the control box 1, and a connecting frame 502 passing through the square opening 501 is fixedly installed at the rear side of the moving plate 402, and a moving box 503 is fixedly installed at the bottom of the connecting frame 502, and a brush plate 504 is provided at the front side of the moving box 503. The moving box 503 and the brush plate 504 are connected to the rear side of the moving plate 402 through the connecting frame 502, and when the moving plate 402 moves, the moving box 503 and the brush plate 504 can be driven to move, so that the brush plate 504 passes through the heat dissipation hole 7, and the hair or dust adhering to the heat dissipation hole 7 is cleaned, thereby improving the heat dissipation efficiency of the heat dissipation hole 7.

[0025] In this embodiment, the cleaning component 5 also includes a cam 505, a connecting shaft 506, a moving wheel 507 and a second spring 508. The rear side of the inner cavity of the moving box 503 is rotatably connected with the connecting shaft 506, the outer side of the cam 505 is fixedly sleeved with the cam 505, and moving wheels 507 are fixedly installed at both ends of the connecting shaft 506.

[0026] In this embodiment, there are a plurality of second springs 508 . In a free state, the rear side of the brush plate 504 fits against the outer side of the cam 505 , and the brush strip on the brush plate 504 is movably sleeved on the front side of the moving box 503 .

[0027] In this embodiment, the outer side of the moving wheel 507 is tightly fitted with the rear side of the control box 1. When the moving box 503 moves, the moving wheel 507 and the control box 1 are tightly fitted, and there is friction, thereby driving the moving wheel 507 and the connecting shaft 506 to rotate, thereby driving the cam 505 to rotate, and utilizing the shape characteristics of the cam 505 to push the brush plate 504 to move outward, so that the brush strips on the brush plate 504 are moved out of the moving box 503 for cleaning the heat dissipation holes 7. When charging is not needed, the moving wheel 507 moves in the opposite direction, thereby driving the brush plate 504 to move toward the inside of the moving box 503, so as to separate the dust and impurities on the brush strips from the brush strips, and facilitate the continuous use of the brush plate 504.

[0028] In this embodiment, a collecting box 6 is fixedly installed at the lower rear side of the control box 1 to collect the cleaned impurities for subsequent processing.

[0029] Working principle: When using the device, a dust blocking component 4 is provided on the rear side of the circuit breaker unit 3. When the circuit breaker unit 3 is in the closed state, the structure in the control box 1 is not in use and does not generate heat. The heat dissipation holes 7 on the control box 1 are blocked by the movable plate 402, so that the control box 1 is in a sealed state, preventing external dust from entering the control box 1; When any one of the circuit breaker units 3 is in the closed state, the movable rod 404 can be driven to move backward, and the second magnet 410 can be driven to move in the movable box 405. Since the second magnet 410 and the first spring 408 have the same magnetic pole on a side close to each other, the first magnet 409 and the push plate 406 are pushed to move backward. Since the push plate 406 is connected to the movable plate 402 by the connecting rod 407, the movable plate 402 is driven to move, so that the connecting hole 403 is connected to the heat dissipation hole 7, and the heat dissipation hole 7 on the control box body 1 is opened for heat dissipation; At this time, when the moving plate 402 moves, the moving box 503 and the brush plate 504 can be driven to move. When the moving box 503 moves, the moving wheel 507 and the control box body 1 are closely fitted and have friction, thereby driving the moving wheel 507 and the connecting shaft 506 to rotate, thereby driving the cam 505 to rotate, and utilizing the shape characteristics of the cam 505 to push the brush plate 504 to move outward, so that the brush strips on the brush plate 504 are moved out of the moving box 503 for cleaning the heat dissipation holes 7; When any circuit breaker unit 3 is not closed, the first spring 408 is used to make the movable plate 402 move in the reverse direction. At this time, the movable wheel 507 moves in the reverse direction, thereby driving the brush plate 504 to move toward the inside of the movable box 503, so as to separate the dust and impurities on the brush strip from the brush strip, and the dust and impurities fall into the collection box 6 for collection.
