Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, and in particular relates to a split-type DC charging unit. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. The development of the new energy vehicle industry is inseparable from charging piles. The input end of a charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Integrated DC charging piles have many components, and the coupling between these components is relatively high. Once a component fails, it may affect the normal operation of other components. Furthermore, integrated DC charging piles require more space.

[0003] After dividing the charging pile into a main unit and sub-units, one main unit can control multiple sub-units. The main unit is installed indoors for easy maintenance, and the sub-units can occupy less space. How to reasonably arrange the components in the sub-units to make the cabinets smaller and the wiring easier to maintain is a problem that needs to be solved. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a split-type DC charging unit with a reasonable structure, regular layout, and small space occupation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A split-type DC charging unit includes a cabinet with a door hinged to the front side. A charging gun connector is fixedly installed on any side panel of the cabinet, and a liquid-cooled charging gun is installed on the charging gun connector. A cold source pump is fixedly installed at the bottom of the cabinet near the charging gun connector. An installation plate assembly with a U-shaped cross-section is fixedly connected inside the cabinet.

[0007] The following are further optimizations of the above technical solution by this utility model:

[0008] The mounting plate assembly includes a first mounting plate, a second mounting plate, and a third mounting plate, with the second and third mounting plates respectively located on both sides of the first mounting plate.

[0009] Further optimization: The first mounting plate is separated into a first component mounting unit and a second component mounting unit by a wiring channel on the side near the cabinet door. The first component mounting unit is located above the second component mounting unit.

[0010] Further optimization: The first component mounting unit contains a charging main control module, the second component mounting unit contains an aluminum alloy resistor and five lamp boards, the aluminum alloy resistor is located above the lamp boards, and the connecting components are located below the second component mounting unit.

[0011] Further optimization: The connection components include a first output copper busbar and a second output copper busbar. Both the first and second output copper busbars are fixedly connected to the first mounting plate. A DC fuse is electrically connected to the first output copper busbar, and a shunt is electrically connected to the second output copper busbar. Both the DC fuse and the shunt are electrically connected to the charging gun connector.

[0012] Further optimization: The second mounting plate is divided into a third component mounting unit, a fourth component mounting unit, and a fifth component mounting unit from top to bottom by a cable tray on the side near the left side panel of the cabinet. Three first switching power supplies are set on the second mounting plate above the third component mounting unit, and the three first switching power supplies are arranged alternately from left to right.

[0013] Further optimization: The third component mounting unit is equipped with a second switching power supply; the fourth component mounting unit is equipped with a DC power meter and a flashing relay, with the DC power meter located to the left of the flashing relay; the fifth component mounting unit is equipped with a first electrical terminal clamp, on which an auxiliary AC switch, a static intermediate relay, a time relay, and a wiring terminal are sequentially clamped from left to right.

[0014] Further optimization: The third mounting plate, located on the right side of the cabinet, is equipped with indicator lights, a wireless communication module, a master switch, and a second electrical terminal block from top to bottom.

[0015] Further optimization: The second electrical terminal clamp has two intermediate relays, a discharge circuit fuse, and a wiring terminal connected sequentially from left to right.

[0016] Further optimization: A base is detachably fixed to the bottom of the cabinet.

[0017] This utility model utilizes the mounting plate assembly to rationally arrange the space inside the cabinet, making efficient use of the internal space and effectively reducing the cabinet's volume. This, in turn, reduces the space occupied by the charging units, making better use of land resources. The components are installed in their respective mounting units according to their size and connection relationships, resulting in a more rational component layout, easier wiring, and a more aesthetically pleasing overall structure. A base is designed at the bottom of the cabinet; if the base becomes damp or damaged, only the base needs to be replaced, effectively protecting the cabinet and avoiding significant economic losses caused by cabinet damage.

Detailed Implementation

[0024] like Figure 1-4 As shown, a split-type DC charging unit includes a cabinet 1, a cabinet door 2 hinged to the front of the cabinet 1, and a card reader 201 installed on the cabinet door 2.

[0025] A charging gun connector 3 is fixedly installed on the right side panel of cabinet 1. A liquid-cooled charging gun is installed on the charging gun connector 3. A cold source pump 4 is fixedly installed at the bottom of cabinet 1 near the charging gun connector 3. The outlet and return outlet of the cold source pump 4 are connected to the cooling pipe of the liquid-cooled charging gun. The coolant circulates through the cooling pipe to cool the liquid-cooled charging gun.

[0026] In addition to this embodiment, the charging gun connector 3 can also be fixedly installed on the left side panel of the cabinet 1.

[0027] The cabinet 1 is fixedly connected to a first mounting plate 5, a second mounting plate 6 and a third mounting plate 7. The second mounting plate 6 and the third mounting plate 7 are respectively located on both sides of the first mounting plate 5. The first mounting plate 5, the second mounting plate 6 and the third mounting plate 7 form a mounting plate assembly with a cross-sectional shape of "U".

[0028] This design allows the components to be arranged reasonably on the mounting plate assembly, making good use of the internal space of cabinet 1, which helps to reduce the volume of cabinet 1 and thus reduce the space occupied by the charging unit.

[0029] The first mounting plate 5, near the cabinet door 2, is divided into a first component mounting unit and a second component mounting unit by a wiring groove 8. The first component mounting unit is located above the second component mounting unit.

[0030] The first component mounting unit is equipped with a charging main control module 501.

[0031] The charging main control module 501 is a control component that controls the charging process of the charging unit, realizing automated and intelligent control of electric vehicle charging on the charging unit.

[0032] The second component mounting unit is equipped with an aluminum alloy resistor 502 and five lamp boards 503. The aluminum alloy resistor 502 is located above the lamp board 503, and the five lamp boards 503 are arranged in parallel at intervals in the vertical direction.

[0033] This design allows components to be installed in their respective mounting units according to their size and connection relationships, resulting in a more rational component layout, easier wiring, and a more aesthetically pleasing overall structure.

[0034] A connection component is located below the second component mounting unit, and the connection component is close to the charging gun connector 3.

[0035] The connection assembly includes a first output copper busbar 504 and a second output copper busbar 506. Both the first output copper busbar 504 and the second output copper busbar 506 are fixedly connected to the first mounting plate 5. A DC fuse 505 is electrically connected to the first output copper busbar 504, and a shunt 507 is electrically connected to the second output copper busbar 506. Both the DC fuse 505 and the shunt 507 are electrically connected to the charging gun connector 3.

[0036] This design is reasonable, with the connecting components close to the charging gun connector 3 and the cold source pump 4, which facilitates the installation and connection of the liquid-cooled charging gun.

[0037] The second mounting plate 6, located near the left side panel of the cabinet 1, is divided into a third component mounting unit, a fourth component mounting unit, and a fifth component mounting unit from top to bottom by a wiring channel 8.

[0038] Three first switching power supplies 601 are arranged on the second mounting plate 6 above the third component mounting unit, and the three first switching power supplies 601 are arranged alternately from left to right.

[0039] The first switching power supply 601 has the model number LM150-22B12-Q.

[0040] The third component mounting unit is equipped with a second switching power supply 602.

[0041] The second switching power supply 602 is model LM350-12B24-Q.

[0042] With this design, the second switching power supply 602 is located below the three first switching power supplies 601, resulting in a reasonable and aesthetically pleasing layout.

[0043] The fourth component mounting unit is equipped with a DC power meter 603 and a flashing relay 604, with the DC power meter 603 located to the left of the flashing relay 604.

[0044] The fifth component mounting unit is fixedly connected to the first electrical terminal clamp 605, which is sequentially clamped to the first electrical terminal clamp 605 from left to right, including an auxiliary AC switch, a static intermediate relay, a time relay, and a wiring terminal.

[0045] This design allows components to be installed in their respective mounting units according to their size and connection relationships, resulting in a more rational component layout, easier wiring, and a more aesthetically pleasing overall structure.

[0046] The third mounting plate 7, located on the side closest to the right side panel of the cabinet 1, is equipped with an indicator light 701, a wireless communication module 702, a master switch 703, and a second electrical terminal clamp 704, arranged sequentially from top to bottom.

[0047] The specification of the wireless communication module 702 is CAT1-WH601.

[0048] The second electrical terminal block 704 has two intermediate relays, a discharge circuit fuse, and a wiring terminal connected sequentially from left to right.

[0049] This design allows components to be installed in their respective mounting units according to their size and connection relationships, resulting in a more rational component layout, easier wiring, and a more aesthetically pleasing overall structure.

[0050] A base 9 is detachably fixed to the bottom of cabinet 1.

[0051] This design avoids the problem of the bottom of cabinet 1 being easily damaged by moisture and rust. The base 9 is designed under cabinet 1 and contacts the ground. If it is damaged by moisture and rust, only the base 9 needs to be replaced, which effectively protects cabinet 1 and avoids the economic loss of replacing the entire cabinet 1.

[0052] Multiple bolts are fixed to the top surface of the base 9. The bolts pass through the bottom surface of the cabinet 1 and are threaded with wing nuts 10. The wing nuts 10 can quickly fix the base 9 to the cabinet, thus facilitating the quick replacement of the base 9 if it is damaged.

[0053] The split-type DC charging pile includes a main unit that can control multiple sub-units. Charging modules and other components are installed inside the main unit, which can be installed indoors for easy maintenance. The sub-units are set up separately, and through reasonable design and assembly of components, they are smaller in size and occupy less space.

[0054] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
