Technical Field
[0001] This application relates to the technical field of DC chargers, and in particular to a DC charger with multi-power compatibility. Background Art
[0002] A DC charger is a charging device that provides DC electrical energy for electric vehicles. It can directly charge the batteries of electric vehicles without the need for conversion through an on-vehicle charger. Therefore, the charging speed is usually faster than AC charging. For this reason, DC chargers are widely used in places such as bus stations and external operation charging stations to provide charging services for electric vehicles due to their advantages of high power, high output current, and short charging time.
[0003] A DC charger includes a charging module. The charging module is responsible for converting alternating current into direct current and providing it for charging electric vehicles. Since different models of vehicles use different battery technologies, the power of the charging modules suitable for different models will vary. Currently, it is difficult to replace the charging modules of DC chargers, resulting in poor applicability of DC chargers. Summary of the Invention
[0004] In order to improve the convenience of disassembly and assembly of the charging module, this application provides a DC charger with multi-power compatibility.
[0005] A DC charger with multi-power compatibility provided by this application adopts the following technical solutions:
[0006] A DC charger with multi-power compatibility includes a frame and an air inlet window. The air inlet window is detachably installed on one side of the wide side of the frame. A module support is arranged inside the frame. The module support includes a mounting plate. The mounting plate is fixed inside the frame. The mounting plate is located on one side of the air inlet window. A guide plate group is arranged on the top surface of the mounting plate. There are two guide plate groups. The two guide plate groups are distributed along the wide side of the mounting plate. An installation channel is arranged between the two guide plate groups. The bottom of the charging module is adaptively inserted into the installation channel. A butting plate is installed on the top of the frame. The bottom surface of the butting plate abuts against the top surface of the charging module.
[0007] By adopting the above technical solution, when it is necessary to replace the charging module with other power, the air inlet window is disassembled from the rack, and then the air inlet window is moved away from one side of the rack, so that an outlet is formed on one side of the rack. Then, the operator grasps one end of the charging module and moves the charging module out of the outlet along the installation channel. Finally, the charging module with other power enters the top surface of the mounting plate from the outlet, and the charging module is pushed along the long side direction of the installation channel until the installation is completed. Then, the air inlet window is installed on the rack, and the air inlet window seals the outlet, thus completing the replacement of the charging module with other power. By installing the charging module through the mounting plate, the guiding plate and the abutting plate, the disassembly and assembly convenience of the charging module is improved, and thus the applicability of the DC charger is improved.
[0008] Preferably, the module bracket further includes a guiding plate, the guiding plate is fixed between the abutting plate and the mounting plate, the guiding plate is located at one end of the mounting plate close to the air inlet window, there are two guiding plates, and the two guiding plates are distributed along the wide side of the mounting plate, and the space between the two guiding plates corresponds to the installation channel.
[0009] By adopting the above technical solution, under the action of the two guiding plates, the charging module can be guided, so that the charging module can better enter the installation channel, and the situation that the charging module is not well aligned with the installation channel is reduced.
[0010] Preferably, the module bracket further includes a baffle, the baffle is fixed between the abutting plate and the mounting plate, the baffle is located at one end of the mounting plate away from the air inlet window, and an installation groove is formed through the side wall of the baffle.
[0011] By adopting the above technical solution, under the action of the baffle, the charging module can be limited, further improving the connection stability between the charging module and the module bracket. At the same time, it can also play a role in resisting, reducing the damage to other workpieces caused by the force applied to move the charging module. One end of the charging module close to the baffle passes through the installation groove and is inserted into the output terminal, thus completing the installation of the charging module.
[0012] Preferably, an air outlet window is installed on one side of the rack away from the air inlet window, and the air inlet window and the air outlet window are arranged opposite to each other.
[0013] By adopting the above technical solution, under the action of the air inlet window and the air outlet window, ventilation can be achieved, thereby reducing the temperature inside the rack and reducing the damage to the workpieces inside the rack caused by high temperature.
[0014] Preferably, the air inlet window and the air outlet window are louver windows.
[0015] By adopting the above technical solution, the air inlet window and the air outlet window are louver windows, and the openings of the air inlet window and the air outlet window face downward. Therefore, when rain drifts to one side of the frame, the air inlet window and the air outlet window can block the rain outside, and then the water flows down along the bottoms of the air inlet window and the air outlet window, so that the waterproof function can be achieved while ensuring ventilation.
[0016] Preferably, a dust-proof net is installed on the inner side of the air inlet window.
[0017] By adopting the above technical solution, under the action of the dust-proof net, the situation of dust entering the inside of the frame can be reduced, and further, the situation of the dust damaging the workpieces inside the frame can be reduced.
[0018] Preferably, there are two abutting plates, and the two abutting plates are symmetrically distributed at both ends of the top of the frame.
[0019] By adopting the above technical solution, under the action of the two abutting plates, the top of the charging module is limited, thereby further improving the connection stability of the charging module installed in the frame.
[0020] Preferably, the guiding plate is a "C"-shaped plate.
[0021] By adopting the above technical solution, the guiding plate is a "C"-shaped plate, which makes the structural stability of the guiding plate stronger. At the same time, the side of the guiding plate can guide the movement of the charging module, increasing the contact area between the guiding plate and the charging module, so that the movement of the charging module can be guided better, and the situation of the guiding plate being too sharp and damaging the charging module can also be reduced.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When it is necessary to replace the charging module with other power, disassemble the air inlet window and the frame, and then move the air inlet window away from the frame side, so that an outlet is formed on one side of the frame. Then, the operator grasps one end of the charging module and moves the charging module out of the outlet along the installation channel. Finally, the charging module with other power enters the top surface of the mounting plate from the outlet, and the charging module is pushed along the long side direction of the installation channel until the installation is completed. Then, install the air inlet window and the frame again, and the air inlet window seals the outlet, thus completing the replacement of the charging module with other power. By installing the charging module through the mounting plate, the guiding plate and the abutting plate, the disassembly and assembly convenience of the charging module is improved, and further, the applicability of the DC charger is improved.
[0024] 2. Under the action of the two guiding plates, the charging module can be guided, so that the charging module can enter the installation channel better, reducing the situation that the charging module is not well aligned with the installation channel. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0030] The following will further describe the present application in detail Figures 1-4 in conjunction with the appended
[0031] An embodiment of the present application discloses a DC charger with multi - power compatibility.
[0032] Referring to Figure 1 , a DC charger with multi - power compatibility includes a column 1 and a pile body 2. The pile body 2 is fixed on the top surface of the column 1. A stabilizing plate 11 is fixed to the bottom surface of the column 1. The bottom surface area of the stabilizing plate 11 is larger than the bottom surface area of the column 1. When the charger is placed on the ground, the contact area with the ground can be increased. After the stabilizing plate 11 receives the load transmitted by the column 1, the stabilizing plate 11 can better support the column 1. A stiffening plate 12 is fixed to the top surface of the stabilizing plate 11. One side of the stiffening plate 12 is fixed to the bottom of the side wall of the column 1. The number of the stiffening plates 12 depends on specific circumstances. In the embodiment of the present application, there are four stiffening plates 12, and the four stiffening plates 12 are distributed along the four sides of the column 1. Under the action of the stiffening plates 12, the column 1 can be supported. When the column 1 is subjected to a side force, the situation of the column 1 shaking and becoming unstable can be reduced.
[0033] Referring to Figure 1 and 2, the pile body 2 includes a frame 21 and a ventilation component. The ventilation component includes an air inlet window 22 and an air outlet window 23. In the embodiment of the present application, the air inlet window 22 and the air outlet window 23 are louvers. The air inlet window 22 is installed on one side of the wide side of the frame 21, and the air inlet window 22 is fixed to the frame 21 by screws. The air outlet window 23 is installed on the side of the frame 21 away from the air inlet window 22 by screws. The air inlet window 22 and the air outlet window 23 are arranged opposite to each other. Under the action of the air inlet window 22 and the air outlet window 23, ventilation can be achieved, thereby reducing the temperature inside the frame 21 and reducing the damage to the workpieces inside the frame 21 caused by high temperature. The openings of the air inlet window 22 and the air outlet window 23 face downward. Therefore, when rain drifts to one side of the frame 21, the air inlet window 22 and the air outlet window 23 can block the rain outside, and then the water flows down along the bottom of the air inlet window 22 and the air outlet window 23, so that the waterproof function can be achieved while ensuring ventilation. A dust-proof net is installed on the inner side of the air inlet window 22. Under the action of the dust-proof net, the situation of dust entering the inside of the frame 21 can be reduced, and further the situation of dust damaging the workpieces inside the frame 21 can be reduced.
[0034] Refer to Figure 2 and Figure 3 , the pile body 2 further includes a module bracket and a charging module 29. The module bracket includes a mounting plate 24. The mounting plate 24 is fixed inside the frame 21. The mounting plate 24 is located between the air outlet window 23 and the air inlet window 22. The long side of the mounting plate 24 is parallel to the long side of the frame 21, and the wide side of the mounting plate 24 is parallel to the wide side of the frame 21. A guide plate group 25 is fixed on the top surface of the mounting plate 24. The guide plate group 25 includes guide plates. The number of guide plates depends on the specific situation. In the embodiment of the present application, a guide plate group 25 has two guide plates. The two guide plates are distributed along the long side of the mounting plate 24. There are two guide plate groups 25. The two guide plate groups 25 are distributed along the wide side of the mounting plate 24. The two guide plate groups 25 are arranged opposite to each other. An installation channel is formed between the two guide plate groups 25. The charging module 29 is inserted into the installation channel in a matching manner. The two sides of the charging module 29 are respectively abutted against the side walls of the guide plates close to it, thereby limiting the charging module 29.
[0035] A butting plate 26 is fixed on the top of the frame 21. The long side of the butting plate 26 is parallel to the wide side of the frame 21. The bottom surface of the butting plate 26 abuts against the top surface of the charging module 29. There are two butting plates 26. The two butting plates 26 are symmetrically distributed at both ends of the top of the frame 21. Under the action of the butting plate 26, the top of the charging module 29 is limited, thereby further improving the connection stability of the charging module 29 installed in the frame 21.
[0036] Refer to Figure 4, a handle is provided on one side of the charging module 29 close to the air inlet window 22. When it is necessary to replace the charging module 29 with other power, the screws between the air inlet window 22 and the frame 21 are removed. Then, the side of the air inlet window 22 away from the frame 21 is moved, so that an outlet is formed on one side of the frame 21. Then, the operator holds the handle tightly and moves the charging module 29 out of the outlet along the installation channel. Finally, the charging module 29 with other power enters the top surface of the mounting plate 24 from the outlet, and the charging module 29 is pushed along the long side direction of the installation channel until the installation is completed. Then, the air inlet window 22 and the frame 21 are installed again, and the air inlet window 22 seals the outlet, thus completing the replacement of the charging module 29 with other power. By installing the charging module 29 through the mounting plate 24, the guide plate and the abutting plate 26, the disassembly and assembly convenience of the charging module 29 is improved, and thus the applicability of the DC charger is improved.
[0037] Referring to Figure 3 , the module bracket further includes a guiding plate 27 and a baffle plate 28. In the embodiment of the present application, the guiding plate 27 is a "C"-shaped plate. The guiding plate 27 is fixed between the abutting plate 26 and the mounting plate 24. The guiding plate 27 is located at one end of the mounting plate 24 close to the air inlet window 22. There are two guiding plates 27, and the two guiding plates 27 are distributed along the wide side of the mounting plate 24. The space between the two guiding plates 27 corresponds to the installation channel. Under the action of the two guiding plates 27, the charging module 29 can be guided, so that the charging module 29 can better enter the installation channel, reducing the situation that the charging module 29 is not well aligned with the installation channel. The baffle plate 28 is fixed between the abutting plate 26 and the mounting plate 24. The baffle plate 28 is located at one end of the mounting plate 24 away from the guiding plate 27. An installation groove is formed through the side wall of the baffle plate 28. When the charging module 29 is pushed to move along the installation channel, under the action of the baffle plate 28, the charging module 29 can be limited, further improving the connection stability between the charging module 29 and the module bracket. At the same time, it can also play a role in resisting, reducing the damage to other workpieces caused by the force applied to move the charging module 29. One end of the charging module 29 close to the baffle plate 28 passes through the installation groove and is inserted into the output terminal, thus completing the installation of the charging module 29.
[0038] The above are all the preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
