[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides a high and low voltage integrated group charging box transformer, such as Figures 1 to 9As shown, it includes a box body 1, a mounting block 2 is arranged on the top of the box body 1, a box cover 3 is arranged on the top of the mounting block 2, grooves are opened at the four corners of the top of the mounting block 2, electric push rods 4 are fixedly installed inside the grooves, the top of the electric push rods 4 are fixedly installed with the bottom of the box cover 3, a plurality of heat dissipation holes 5 are opened on the top of the mounting block 2, a movable groove is opened in the middle of the mounting block 2, two first baffles 6 are arranged inside the movable groove, the plurality of heat dissipation holes 5 pass through the first baffle 6 and the top of the box body 1, two slide grooves are opened on the top of the mounting block 2 and located between the electric push rods 4, a first fixed groove is opened in the middle of the two slide grooves and located at the top of the mounting block 2, a telescopic rod 7 is fixedly installed inside the first fixed groove, a mounting plate 8 is fixedly installed on the top of the telescopic rod 7, the top of the mounting plate 8 is fixedly installed with the bottom of the box cover 3, and rotating rods 9 are hinged at both ends of the mounting plate 8. A slider 10 is hinged at one end of the movable rod 9, and the slider 10 is slidably connected to the slide groove. One side of the slider 10 is fixedly installed on one side of the first baffle 6. A mounting groove is opened inside the first baffle 6, and a second fixed groove is opened on one side of the mounting groove. A first motor 11 is fixedly installed inside the second fixed groove. A threaded rod 12 is transmission-connected to the output end of the first motor 11, and a fixed plate 13 is rotatably connected to one end of the threaded rod 12. A moving block 14 is threadedly connected to one end of the threaded rod 12. The bottom of the moving block 14 is slidably connected to the inner wall of the bottom of the mounting groove. A movable rod 15 is hinged at one side of the moving block 14, and a first telescopic plate 16 is hinged at one end of the movable rod 15. A plurality of second telescopic plates 17 are arranged on one side of the first telescopic plate 16. The first telescopic plate 16 and the second telescopic plate 17, as well as the plurality of second telescopic plates 17, are connected by a fixing rod 18.

[0030] The multiple groups of heat dissipation holes 5 on the top of the mounting block 2 facilitate heat dissipation on the top of the box body 1. When encountering strong winds and heavy rain, the first motor 11 is started first to drive the threaded rod 12 to rotate. The bottom of the moving block 14 is limited by the sliding connection between the bottom of the moving block 14 and the inner wall of the bottom of the mounting groove, so that the moving block 14 moves along the threaded rod 12 toward the first motor 11, and the movable rod 15 is deflected to drive the first telescopic plate 16 to move closer to each other. When the first telescopic plate 16 moves, the fixed rod 18 drives multiple second telescopic plates 17 to move closer to each other at the same time, so that the first baffle 6 and the second baffle 30 block the heat dissipation holes 5 to prevent the heat dissipation holes 5 from causing raindrops to fall when the first baffle 6 moves to the outside of the box body 1, thereby affecting the maintenance of the staff. Then, the electric push rod 4 is started to drive the box cover 3 to move downward, and the box cover 3 drives the installation The plate 8 moves downward, causing the telescopic rod 7 to contract and the rotating rod 9 to deflect all the time, so that the slider 10 moves along the slide groove and drives the first baffle 6 to move to the outside of the moving groove. When the box cover 3 moves to the top of the mounting block 2, the multiple groups of heat dissipation holes 5 on the top of the mounting block 2 are blocked, thereby preventing rainwater from entering the box body 1 through the heat dissipation holes 24 on the top of the box body 1 in strong winds and heavy rains, affecting the use of the equipment inside the box body 1. At the same time, the box cover 3 drives the mounting plate 8 to move to the top of the mounting block 2, and the rotating rod 9 deflects to push the slider 10 to move to the end of the slide groove away from the telescopic rod 7, and drives the first baffle 6 to move to the outside of the mounting block 2, blocking both sides of the box body 1 to prevent rainwater from dripping into the interior of the box body 1 when the protective door 23 is opened for maintenance, causing damage to the equipment inside the box body 1 and affecting the use of the box body 1.

[0031] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, a high-voltage chamber 19 is provided on one side of the interior of the box body 1, a transformer chamber 20 is provided on one side of the high-voltage chamber 19, a low-voltage chamber 21 is provided on one side of the transformer chamber 20, and a charger chamber 22 is provided on one side of the low-voltage chamber 21. Protective doors 23 are provided on one side of the high-voltage chamber 19, the transformer chamber 20, the low-voltage chamber 21 and the charger chamber 22, and a heat dissipation port 24 is provided at the bottom of the protective door 23. An installation port is provided on the top of the box body 1 and located in the middle of the multiple groups of heat dissipation holes 5, and a filter screen 25 is fixedly installed inside the installation port.

[0032] The application terminal set inside the box 1 is used for monitoring and operation, and the cloud platform realizes remote background processing. The AC / DC charging module is used to connect the charging gun or charging terminal through the charger room 22, which is convenient for charging logistics and transport vehicles. The strong power and ultra-fast charging combination create a new era of efficient charging. It is fully compatible with all vehicles and has flexible configuration without waste. The box 1 integrates the high-voltage room 19, the transformer room 20, the low-voltage room 21 and the charger room 22 into one, without the need to plan a separate distribution room. It has reliable operation, convenient maintenance, fast delivery, low failure rate and low civil engineering cost. The independent air duct gluing process is also used as the whole, so it is not afraid of rain, snow, wind and frost, and has strong evolution. Features: one-time investment for 10 years of benefits (easy to expand, upgrade, future technology iteration, no need to demolish and rebuild), can save power station costs, save investment, electricity costs, and losses, power pool sharing, high-efficiency modules, and overall machine efficiency ≥ 95%), save time and effort, and use the smart charging cloud platform for efficient operation. The one-stop management of the platform is more worry-free, and the use of intelligent operation and maintenance is convenient for improving efficiency and easy to use. The heat dissipation port 24 at the bottom of the protective door 23 is convenient for dissipating heat inside the box 1, and the installation port is convenient for improving the heat dissipation effect on the top of the box 1. The filter 25 is convenient for preventing dust and impurities in the air from entering the inside of the box 1 and affecting its use.

[0033] like Figures 2 to 6 As shown, the mounting opening, the plurality of heat dissipation holes 5 are arranged corresponding to the high-voltage chamber 19, the transformer chamber 20, the low-voltage chamber 21, and the charger chamber 22. A compression spring is fixedly installed on the outside of the telescopic rod 7. One end of the rotating rod 9 is located inside the slide groove. The telescopic rod 7, the compression spring, the mounting plate 8, the rotating rod 9 and the slider 10 are symmetrically arranged with respect to the center of the box cover 3. The shape of the slider 10 is L-shaped. A first movable groove is opened on the top of the box cover 3, and a heat dissipation structure 26 is arranged inside the first movable groove.

[0034] Since the installation opening and the heat dissipation holes 5 are arranged corresponding to the high-voltage chamber 19, the transformer chamber 20, the low-voltage chamber 21, and the charger chamber 22, it is convenient to improve the heat dissipation effect of the top of the box body 1, and it is convenient to use the box body 1. When the mounting plate 8 is driven to move downward by the box cover 3, the telescopic rod 7 is contracted, and the compression spring is compressed. Through the L-shaped slider 10, it is convenient to connect the first baffle 6. When the rotating rod 9 can be deflected, the slider 10 drives the first baffle 6 to move, and it can be moved to the outside of the box body 1 to block rainwater. The heat dissipation structure 26 is convenient to install through the first movable groove. The heat dissipation structure 26 improves the heat dissipation effect of the top of the box body 1. At the same time, the movement of the heat dissipation structure 26 can make the top of the first baffle 6 dry through the heat dissipation hole 5, so as to prevent the residual rainwater or the undried part on the top of the first baffle 6 from affecting the use of the internal structure of the box body 1, thereby further improving the use of the box body 1.

[0035] like Figures 5 and 6As shown, guide grooves 27 are provided at both ends of the top of the two first baffles 6, and the side close to the slider 10 is located on the inclined surface. The two first baffles 6 are located on both sides of the installation opening, and the bottoms are slidably connected to the inner wall of the groove.

[0036] The guide groove 27 on the top of the first baffle 6 facilitates rainwater to slide down through the guide groove 27, and the inclined surface on one side of the slider 10 facilitates rainwater to slide down along the inclined surface from both sides of the slider 10 to prevent rainwater from splashing. Therefore, when the protective door 23 is opened, it is reduced that rainwater is easily splashed into the interior of the box 1, causing damage to the equipment inside the box 1 and affecting the use of the equipment set in the box 1.

[0037] like Figures 6 to 9 As shown, the fixed plate 13 is located on one side of the heat dissipation port 24, and its bottom is fixedly installed with the inner wall of the bottom of the mounting groove, the bottoms of the first telescopic plate 16 and the second telescopic plate 17 are both slidably connected with the inner wall of the bottom of the mounting groove, and the telescopic ends of the first telescopic plate 16 and the second telescopic plate 17 are fixedly installed with magnetic blocks 28, which are magnetically connected to each other, the first telescopic plate 16 and the second telescopic plate 17 are both located on both sides of the heat dissipation port 24, the fixed rod 18 is located between the multiple groups of heat dissipation ports 24, and the number of the first telescopic plate 16 and the second telescopic plate 17 is the same as the number of the multiple groups of heat dissipation ports 24.

[0038] The fixing plate 13 facilitates the first motor 11 to drive the threaded rod 12 to rotate and maintain stability. When the threaded rod 12 rotates and drives the moving block 14 to move, the movable rod 15 deflects to make the first telescopic plate 16 move along the bottom inner wall of the installation groove, and drives the second telescopic plate 17 to move close to each other along the bottom inner wall of the installation groove through the fixing rod 18. The fixing rod 18 can drive multiple second telescopic plates 17 to move simultaneously with the first telescopic plate 16. When the first telescopic plate 16 and the second telescopic plate 17 are close to each other, they are magnetically connected by the magnetic block 28, and the first telescopic plate 16 and the second telescopic plate 17 are extended, thereby improving the stability of the second telescopic plate 17 and the second telescopic plate 17 in shielding the heat dissipation hole 5, and preventing the first baffle 6 from moving to the outside of the box body 1. The heat dissipation hole 5 causes raindrops to fall, thereby affecting the maintenance of the staff.

[0039] like Figure 1 to Figure 2 As shown, a second movable groove is opened at the bottom of the mounting block 2 and at the bottom of the movable groove. The second movable groove is located at one end of the mounting block 2 close to the high-pressure chamber 19. An electric telescopic rod 29 is fixedly installed on the inner wall of the second movable groove. A second baffle 30 is fixedly installed at one end of the electric telescopic rod 29. The second baffle 30 is located inside the second movable groove.

[0040] The electric telescopic rod 29 and the second baffle 30 are installed through the second movable groove, and the electric telescopic rod 29 is started to push the second baffle 30 to move out of the second movable groove to the side of the box body 1, so as to block the top of the protective door 23 on the side of the high-pressure chamber 19 of the box body 1, so as to prevent strong wind from causing rainwater to enter the interior of the high-pressure chamber 19, affecting the use of the equipment inside the high-pressure chamber 19 and affecting the use effect.

[0041] like Figure 2 , Fig.10 As shown, the heat dissipation structure 26 includes a second motor 261, the output end of the second motor 261 is transmission-connected with a screw rod 262, the middle part of the screw rod 262 is threadedly connected with a movable block 263, a limiting block is fixedly installed on the top of the movable block 263, the top of the limiting block is slidingly connected to the inner wall of the top of the first movable groove, a cooling fan 264 is fixedly installed on the bottom of the movable block 263, a placement groove is opened on one side of the first movable groove, the second motor 261 is fixedly installed with the placement groove, one end of the screw rod 262 is rotatably connected to the inner wall of the first movable groove, the cooling fan 264 is located at the top of the mounting port, and the number of cooling fans 264 is the same as the mounting port.

[0042] By starting the second motor 261 to drive the screw rod 262 to rotate, the screw rod 262 rotates along the inner wall of the first movable groove, and the movable block 263 rotates back and forth along the screw rod 262 through the limiting effect of the limiting block, so that the cooling fan 264 rotates back and forth to dissipate heat on the top of the box body 1, and can dry the first baffle 6 inside the movable groove to prevent rainwater or undried parts remaining on the top of the first baffle 6 from affecting the use of the internal structure of the box body 1, thereby further improving the use of the box body 1. When the box cover 3 moves to the top of the mounting block 2, the cooling fan 264 moves to the inside of the mounting port, so that after the heat dissipation holes 5 on the top of the box body 1 are blocked, the inside of the box body 1 can still dissipate heat through the rotation of the cooling fan 264, thereby facilitating the use of the box body 1.

[0043] Working principle: When in use, the top of the box body 1 is easily cooled through the multiple groups of heat dissipation holes 5 on the top of the mounting block 2. When encountering strong winds and heavy rain, the first motor 11 is started first to drive the threaded rod 12 to rotate. The bottom of the moving block 14 is limited by the sliding connection between the bottom of the moving block 14 and the inner wall of the bottom of the mounting groove, so that the moving block 14 moves along the threaded rod 12 toward the first motor 11, and the movable rod 15 is deflected to drive the first telescopic plate 16 to move closer to each other. When the first telescopic plate 16 moves, the second telescopic plate 17 is driven to move closer to each other through the fixed rod 18. The first baffle plate 6 and the second baffle plate 30 are magnetically connected through the magnetic block 28 to block the heat dissipation holes 5, and then the electric telescopic rod 29 is started to push the second baffle plate 30 to move to the outside of the second movable groove to the side of the box body 1 close to the high-pressure chamber 19, and then After that, the box cover 3 is driven to move downward by starting the electric push rod 4. When the box cover 3 moves, it drives the mounting plate 8 to move downward, so that the telescopic rod 7 contracts and the rotating rod 9 is always deflected, so that the slider 10 moves along the slide groove and drives the first baffle 6 to move to the outside of the moving groove. When the box cover 3 moves to the top of the mounting block 2, the multiple groups of heat dissipation holes 5 on the top of the mounting block 2 are blocked, thereby preventing rainwater from entering the box body 1 through the heat dissipation port 24 on the top of the box body 1 in strong winds and heavy rains, affecting the use of the equipment inside the box body 1. At the same time, the box cover 3 drives the mounting plate 8 to move to the top of the mounting block 2, and the rotating rod 9 is deflected to push the slider 10 to move to the end of the slide groove away from the telescopic rod 7, and drives the first baffle 6 to move to the outside of the mounting block 2, to block both sides of the box body 1, and then the protective door 23 can be opened for maintenance.

[0044] When the box cover 3 moves to the top of the mounting block 2 to block the heat dissipation holes 5, the heat dissipation fan 264 moves to the inside of the mounting opening, so that after the heat dissipation holes 5 on the top of the box body 1 are blocked, the inside of the box body 1 can still dissipate heat through the rotation of the heat dissipation fan 264. When the first baffle 6 is not needed, the box cover 3 is driven upward by the electric push rod 4, and the movement of the mounting plate 8 and the telescopic rod 7 causes the rotating rod 9 to rotate to drive the slider 10 to move the first baffle 6 to the inside of the mounting block 2, and the heat dissipation fan 264 moves from the inside of the mounting opening. When the cooling fan 264 reaches the top of the box body 1, the second motor 261 is started to drive the screw rod 262 to rotate, so that the screw rod 262 rotates along the inner wall of the first movable groove. The movable block 263 rotates back and forth along the screw rod 262 through the limiting action of the limiting block, so that the cooling fan 264 rotates back and forth to dissipate the heat on the top of the box body 1, and can dry the first baffle plate 6 inside the movable groove to prevent the rainwater or the undried part on the top of the first baffle plate 6 from affecting the use of the internal structure of the box body 1, and can also improve the heat dissipation effect of the top of the box body 1 through the heat dissipation hole 5.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
