Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charging device. Background Technology

[0002] With the development of electric vehicles, the construction of supporting charging infrastructure has also sprung up. Among these, charging equipment (e.g., charging piles) can provide charging services for electric vehicles and are therefore widely installed in charging stations. To enable a single charging device to charge multiple devices (e.g., electric vehicles), a charging device may include multiple charging connectors (e.g., charging guns).

[0003] When charging equipment includes multiple charging ports, the equipment cabinet typically requires numerous power distribution devices (e.g., switches, fuses, etc.), which occupy a significant amount of space within the cabinet. To reduce the size of the charging equipment, in related technologies, the control board is usually installed in an unused space within the cabinet. This can lead to the power distribution devices obstructing the control board, or vice versa. When maintenance of the control board or power distribution devices is required, both must be removed from the cabinet, hindering the maintenance of the charging equipment. Summary of the Invention

[0004] This application provides a charging device, which facilitates the maintenance of the charging device by rationally arranging the internal layout of the device cabinet.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a charging device, which includes a cabinet, a first cabinet door, multiple first switching devices, multiple charging connectors, and multiple cables. The cabinet includes a first cabinet panel and a second cabinet panel arranged along its thickness direction; the first cabinet door is connected to the second cabinet panel or the first cabinet panel; the multiple first switching devices are located inside the cabinet and fixed to the first cabinet panel, and are arranged along the width direction of the cabinet, with the input terminals of the multiple first switching devices used for electrical connection to a power source; the multiple charging connectors are located outside the cabinet and are used for connection to the device to be charged; the first cabinet panel has outlet holes for multiple cables to pass through, the outlet holes being located above the first switching devices, the portion of each cable outside the cabinet being electrically connected to a charging connector, and the portion of each cable inside the cabinet being electrically connected to the output terminal of at least one first switching device; the charging device also includes a first control board and / or a second control board, the first control board being fixed inside the cabinet and located on the side of the multiple first switching devices away from the first cabinet door, one side of the first control board facing the first cabinet door, and the first control board being located above the outlet holes; the second control board is fixed to the second cabinet panel, and one side of the second control board facing the first cabinet panel.

[0007] The input terminals of multiple first switching devices are connected to a power source (e.g., the power grid). After power conversion, the current supplied by the power source is input to the first switching devices through the input terminals of the first switching devices. When the first switching device is closed, the first switching device allows current to be output from the output terminal of the first switching device. The current output from the output terminal of the first switching device is transmitted to multiple charging connectors through multiple cables, and then charged multiple devices (e.g., electric vehicles) through the multiple charging connectors.

[0008] In the case where the charging equipment includes a first control board, the first control board is positioned on the side of the first switching device facing away from the first cabinet door. When maintenance of the first switching device is required, opening the first cabinet door reduces interference from the first control board during maintenance. Furthermore, the distance between the first control board and the first cabinet door also reduces the likelihood of damage to the first control board during maintenance of other devices within the cabinet, thus protecting the circuit board.

[0009] Furthermore, multiple first switching devices are located inside the equipment cabinet and fixed to the first cabinet panel. Since these first switching devices are arranged along the width of the equipment cabinet, they occupy a significant amount of space. In the case of a charging device including a first control board, positioning the first control board above the cable outlet allows for a staggered arrangement of the first control board and the multiple first switching devices, reducing the width of the equipment cabinet. Moreover, the multiple first switching devices do not obstruct the first control board, and the portion of the cable inside the equipment cabinet does not significantly obstruct the first control board. After opening the first cabinet door, the first control board can be inspected and maintained without disassembling the first switching devices or cables.

[0010] Furthermore, when the charging equipment includes a second control board, the second control board is fixed to the second cabinet panel, reducing the possibility of interference between the second control board and the first switching devices. After opening the first cabinet door, maintenance can be performed on multiple first switching devices facing the first cabinet panel, and maintenance can be performed on the second control board facing the second cabinet panel, which is beneficial for the maintenance of the charging equipment.

[0011] In one embodiment of this application, multiple electronic components on the first control board face the first cabinet door.

[0012] With the first cabinet door closed, multiple electronic components (including the controller) on the first control board face the first cabinet door. When maintenance of the first control board is required, after opening the first cabinet door, the multiple electronic components on the first control board face the personnel, making it convenient for personnel to maintain the electronic components on the first control board.

[0013] In one embodiment of this application, the charging device further includes a display screen, which is fixed to a second cabinet panel. The display area of ​​the display screen is exposed outside the equipment cabinet, and a second control board is located above the display screen.

[0014] The display screen is fixed to the second cabinet panel. After the equipment cabinet is installed, the display screen can face personnel so that they can observe the content on the screen. By installing the display screen on the equipment cabinet (not on the first cabinet door), when maintenance is needed on the devices inside the equipment cabinet, the position of the display screen will not change during the opening of the first cabinet door (the display screen will not move with the first cabinet door). This prevents the electronic wires connected to the display screen from being pulled out due to the movement of the first cabinet door, reducing the difficulty of maintenance for personnel inside the equipment cabinet. Furthermore, in this application, the power distribution device (including multiple first switching devices) and the display screen inside the equipment cabinet are located on different sides of the first cabinet door. After opening the first cabinet door, maintenance can be performed on the multiple first switching devices facing the first cabinet panel, and on the display screen facing the second cabinet panel, improving maintenance efficiency.

[0015] With the second control board also fixed on the second cabinet panel, positioning it above the display screen increases its height, reducing the risk of water damage should the charging equipment get inside. Furthermore, with both the first and second control boards fixed inside the cabinet, and since the first control board is higher than the cable outlet (its position is higher), positioning the second control board higher as well allows it to be closer to the first, facilitating the connection between the two boards via electronic wiring.

[0016] In one embodiment of this application, the charging device further includes a power supply device located inside the equipment cabinet and connected to the second cabinet panel. The power supply device is located below the display screen. The power supply device is electrically connected to the power source and is also electrically connected to the first control board and / or the second control board. The power supply device is used to convert the electrical energy input from the power source into power and output it to the first control board and / or the second control board to supply power to the first control board and / or the second control board.

[0017] The power supply unit is an auxiliary power source. Since the first switching device on the first cabinet panel requires cable connections, placing the power supply unit on the second cabinet panel reduces the impact of the power supply unit on the wiring of the first switching device. Furthermore, the second control board is located above the display screen, and the power supply unit is located below the display screen. The arrangement of the second control board, display screen, and power supply unit along the height of the equipment cabinet reduces the width of the equipment cabinet, minimizing its footprint and allowing the display screen to be positioned for easy viewing.

[0018] In one embodiment of this application, the power supply device is capable of sliding relative to the second cabinet panel in a direction close to or away from the first cabinet door.

[0019] The power supply unit is designed to slide relative to the equipment cabinet, facilitating its installation and removal. Specifically, when pulling out the power supply unit, it slides towards or away from the first cabinet door. After opening the first cabinet door, the internal space of the equipment cabinet is connected to the external space. Personnel can then pull the power supply unit outwards, gradually moving it outside the equipment cabinet to remove it. To install the power supply unit, it is pushed inwards towards the equipment cabinet. Once inside the cabinet, it is continuously pushed away from the first cabinet door to complete the installation.

[0020] In one embodiment of this application, the charging device further includes a second switching device, which is fixed to a second cabinet plate. The second switching device and the power supply device are arranged along the height direction of the equipment cabinet. The input terminal of the second switching device is used to be electrically connected to the power supply, and the output terminal of the second switching device is electrically connected to the power supply device.

[0021] The second switching device (e.g., circuit breaker, contactor, etc.) can control the on / off of the circuit between the power supply device and the power source. Fixing the second switching device on the second cabinet plate allows the second switching device and the power supply device to be arranged along the height of the equipment cabinet, which not only makes full use of the space below the display screen, but also reduces the size of the equipment cabinet in the width direction, making the internal layout of the equipment cabinet more reasonable.

[0022] In one embodiment of this application, the charging device further includes a second cabinet door, which is arranged along the width of the device cabinet with the first cabinet door, and the second cabinet door is connected to the second cabinet panel or the first cabinet panel.

[0023] The first control board is located on the side of the multiple first switching devices facing the second cabinet door. In other words, the first control board is close to the second cabinet door. If it is necessary to disassemble the first control board, the second cabinet door can be opened to expose the first control board, making it convenient for personnel to disassemble the first control board.

[0024] In one embodiment of this application, the charging device further includes multiple meters, with one meter fixed on each of the first and second cabinet doors. The meter on the first cabinet door is exposed outside the equipment cabinet through a window on the first cabinet door, and the meter on the second cabinet door is exposed outside the equipment cabinet through a window on the second cabinet door. The cable outlet includes a first cable outlet and a second cable outlet arranged along the width direction of the equipment cabinet, with the first cable outlet located on the side of the second cable outlet facing the first cabinet door. The multiple charging connectors include a first charging connector and a second charging connector. The first charging connector is electrically connected to a cable passing through the first cable outlet, and the second charging connector is electrically connected to a cable passing through the second cable outlet. The meter on the first cabinet door is used to display the charging data of the first charging connector, and the meter on the second cabinet door is used to display the charging data of the second charging connector.

[0025] The electricity meter displays the charging data of the charging connectors, thus measuring the amount of charge received by the charging equipment. Since the charging equipment includes multiple charging connectors, and the first and second cable outlets are arranged along the width of the equipment cabinet, the cables extending from both outlets are also arranged along the width of the cabinet. Personnel need to stand on different sides of the cabinet to use the first and second charging connectors. For example, when using the first charging connector, personnel are typically closer to the first cabinet door, and when using the second charging connector, they are typically closer to the second cabinet door. Different electricity meters are installed on the first and second cabinet doors, with their display areas exposed outside the cabinet through corresponding windows. When personnel use the first charging connector to charge the equipment, observing the meter on the first cabinet door reveals the charging status; similarly, when personnel use the second charging connector, observing the meter on the second cabinet door reveals the charging status. The meters located on different sides of the cabinet facilitate easy observation of charging values ​​when personnel use different charging connectors.

[0026] In addition, both the first and second cabinet doors are adjacent to the second cabinet panel where the display screen is located. Electricity meters are installed on the first and second cabinet doors, which makes it easy for people to compare the data displayed on the display screen with the data displayed on the electricity meter.

[0027] In one embodiment of this application, the charging device further includes a protective cover, which is fixed inside the equipment cabinet and located on the side of the plurality of first switching devices facing the first cabinet door, and the protective cover shields the first switching devices.

[0028] After opening the first cabinet door, the protective cover can shield multiple first switching devices, preventing them from being exposed. This protects both personnel and the switching devices themselves. When maintenance of the first switching devices is required, the protective cover can be removed.

[0029] In one embodiment of this application, the charging device further includes a functional component, which includes at least one of a heating device, a turbulence fan, or an emergency stop button. The functional component is located inside the equipment cabinet and fixed to the first cabinet door. The heating device is used to heat the internal space of the equipment cabinet, the turbulence fan is used to blow air into the equipment cabinet, and the emergency stop button is used to control the first switching device to disconnect the circuit between the power supply and the charging connector.

[0030] At least one of the heating element, a baffle fan, or an emergency stop button is located on the first cabinet door. When the first cabinet door is opened, the functional components (heating element, baffle fan, or emergency stop button) are exposed, facilitating maintenance. However, since the devices on the first cabinet door will inevitably come into contact with personnel or maintenance tools when opened, and these components are not easily damaged, placing them on the first cabinet door provides more space on both the first and second cabinet panels for installing easily damaged devices (e.g., circuit boards, electronic components). While some less easily damaged devices (e.g., the aforementioned functional components) are exposed when the first cabinet door is opened, others remain inside the cabinet, resulting in a more rational layout of the internal components and extending the overall lifespan of the charging equipment.

[0031] In one embodiment of this application, the charging device further includes a baffle fixed to a first cabinet door, the baffle extending toward the interior space of the equipment cabinet, and the baffle located above the functional components.

[0032] After the first cabinet door is opened, the presence of the baffle can partially block and prevent liquid dripping from the top of the first cabinet door, reducing the possibility of short circuits between multiple devices on the first cabinet door caused by the dripping liquid.

[0033] In one embodiment of this application, the charging device further includes multiple charging gun holders, which are fixed to a second cabinet plate, located below the display screen, and arranged along the width of the equipment cabinet.

[0034] By fixing the gun mount to the second cabinet panel, the gun mount and its charging connector will not move with the opening of the first cabinet door. Furthermore, arranging the gun mount and display screen along the height of the equipment cabinet reduces the cabinet's width and floor space.

[0035] In one embodiment of this application, the charging device further includes a card reader, which is fixed to the first cabinet panel and exposed outside the cabinet. The card reader and the display screen are arranged along the height of the cabinet.

[0036] The card reader is used to identify IC cards (Integrated Circuit Cards), enabling the charging equipment to recognize the user's IC card (bank card, charging card, etc.) and deduct the corresponding charging fee. The card reader and display screen are arranged along the height of the equipment cabinet, which reduces the cabinet's width and floor space.

[0037] In one embodiment of this application, the charging device further includes a mounting plate, which is fixed to the bottom of the equipment cabinet. At least part of the mounting plate is located on the outside of the equipment cabinet. The portion of the mounting plate located on the outside of the equipment cabinet has a through hole for fasteners to pass through. The fasteners are used to fix the mounting plate in a designated position.

[0038] The mounting plate extends to the outside of the equipment cabinet, with through holes for fasteners such as screws or rivets to pass through. After the fasteners pass through the through holes, the mounting plate can be locked into a designated area (e.g., the ground or mounting base), thus securing the equipment cabinet. In other words, during the installation of the charging equipment, personnel can complete the installation without opening the equipment cabinet. Attached Figure Description

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0055] In this application, unless otherwise expressly stated and limited, "multiple" means two or more.

[0056] Furthermore, in this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0057] In the accompanying drawings of the embodiments of this application, solid structures such as components and assemblies are represented by guide lines; structures composed of multiple components are represented by guide lines with parentheses or solid arrows; and hollow structures such as openings, holes, spaces, and cavities are represented by guide lines with hollow arrows.

[0058] This application provides a charging device 100, Figure 1 An exemplary structure of a charging device 100 is shown, with reference to Figure 1 The charging equipment 100 is an integrated charging pile. The charging equipment 100 includes an equipment cabinet 101, a power conversion device 102, an AC power distribution device 103, and a first DC power distribution device 104. The power conversion device 102, the AC power distribution device 103, and the first DC power distribution device 104 are all installed inside the equipment cabinet 101.

[0059] The input terminal of the AC power distribution device 103 is used to connect to the power source 200, which can be the power grid. The output terminal of the AC power distribution device 103 is connected to the input terminal of the power conversion device 102, which converts the AC power input from the power source 200 through the AC power distribution device 103 into DC power before outputting it. The output terminal of the power conversion device 102 is connected to the input terminal of the first DC power distribution device 104.

[0060] In addition, refer to Figure 1 The charging device 100 also includes a plurality of charging connectors 105 (e.g., charging guns) and a plurality of cables 106 (e.g., charging gun cables), in Figure 1 In the illustrated embodiment, two charging connectors 105 and two cables 106 are provided. Multiple charging connectors 105 are located outside the equipment cabinet 101 and are used to connect to the device to be charged (e.g., an electric vehicle). Each charging connector 105 is connected to the first DC power distribution device 104 via a corresponding cable 106.

[0061] The first DC power distribution device 104 includes multiple first switching devices 1041 (e.g., air switches, relays, or contactors, etc.). The output terminal of the power conversion device 102 is electrically connected to the input terminals of the multiple first switching devices 1041, and the output terminals of the multiple first switching devices 1041 are electrically connected to multiple cables 106. When the multiple first switching devices 1041 conduct the circuit between the power conversion device 102 and the multiple cables 106, the power output of the power conversion device 102 can be transmitted to the multiple charging connectors 105 through the multiple cables 106. When the multiple first switching devices 1041 disconnect the circuit between the power conversion device 102 and the multiple cables 106, the multiple charging connectors 105 cannot access the power output of the power conversion device 102.

[0062] Figure 2 An exemplary structure of another charging device 100 is shown, with reference to Figure 2 The charging device 100 is a split-type charging pile, comprising a main unit and multiple terminal units. The main unit includes a main unit cabinet 107, a power conversion device 102, an AC power distribution device 103, and a second DC power distribution device 108, all installed within the main unit cabinet 107. The input terminal of the AC power distribution device 103 is connected to a power source 200 (e.g., the power grid). The power conversion device 102 converts the AC power input from the power source 200 into DC power before outputting it. The second DC power distribution device 108 distributes the DC power output from the power conversion device 102 to one or more terminal units.

[0063] Each terminal section of the charging device 100 includes a device cabinet 101, a first DC power distribution unit 104, multiple charging connectors 105, and multiple cables 106, for example, in Figure 2In the illustrated embodiment, each terminal section has two charging connectors 105 and two cables 106. A first DC power distribution device 104 is installed inside an equipment cabinet 101, while the multiple charging connectors 105 are located outside the cabinet 101. The first DC power distribution device 104 includes multiple first switching devices 1041. The input terminals of the multiple first switching devices 1041 are electrically connected to a second DC power distribution device 108, and the output terminals of the multiple first switching devices 1041 are electrically connected to the multiple charging connectors 105 via multiple cables 106. This allows the multiple charging connectors 105 to output current (from the power supply 200) after power conversion by the power conversion device 102.

[0064] by Figure 2 Taking the charging device 100 in the example, Figure 3 An example is shown Figure 2 A partial structure of the charging device 100 (the terminal part of the charging device 100). Figure 4 An example is shown Figure 3 The internal structure of the charging device 100 is referenced. Figure 3 and Figure 4 The charging device 100 includes a cabinet 101 and a first cabinet door 109. The cabinet 101 has a first opening 1013 (access panel) communicating with its internal space. The walls of the cabinet 101 enclosing its internal space include a first cabinet panel 1011 and a second cabinet panel 1012. The first cabinet panel 1011 and the second cabinet panel 1012 are arranged along the thickness direction (Y-axis direction) of the cabinet 101 and are positioned opposite each other. The first opening 1013 is located between the first cabinet panel 1011 and the second cabinet panel 1012. For example, after the cabinet 101 is installed, the first cabinet panel 1011 can be the rear cabinet panel of the cabinet 101, and the second cabinet panel 1012 can be the front cabinet panel of the cabinet 101.

[0065] In its closed state, the first cabinet door 109 is located between the first cabinet panel 1011 and the second cabinet panel 1012, and the first cabinet door 109 is connected to either the first cabinet panel 1011 or the second cabinet panel 1012, as shown in the reference. Figure 4 Taking the first cabinet door 109 connected to the first cabinet panel 1011 as an example, the first cabinet door 109 can move relative to the equipment cabinet 101 (including rotation, sliding, etc.). For example, the first cabinet door 109 is hinged to the first cabinet panel 1011 (connected by a hinge). The first cabinet door 109 can open or close the equipment cabinet 101. For example, when the first cabinet door 109 closes the first opening 1013, the first cabinet door 109 also closes the equipment cabinet 101. When the first cabinet door 109 opens the first opening 1013, the first cabinet door 109 also opens the equipment cabinet 101. Figure 3This illustrates the situation where the first cabinet door 109 blocks the first opening 1013 (the first cabinet door 109 is in a closed state and blocks the equipment cabinet 101). Figure 4 The diagram shows the first cabinet door 109 with the first opening 1013 open (the first cabinet door 109 is in the open state and the equipment cabinet 101 is open).

[0066] The equipment cabinet 101 can be fixed in a designated location by any suitable method, for example, referring to... Figure 3 The charging device 100 also includes a mounting plate 110, which is fixed to the bottom of the equipment cabinet 101. The mounting plate 110 is at least partially located on the outside of the equipment cabinet 101, meaning it extends to the outside of the equipment cabinet 101. Furthermore, the portion of the mounting plate 110 located on the outside of the equipment cabinet 101 has a through hole 1101, through which fasteners can pass. For example, screws or rivets can pass through the through hole 1101. After the fastener passes through the through hole 1101, the mounting plate 110 can be locked in a designated position (e.g., the ground or countertop where the equipment cabinet 101 is installed), thus securing the equipment cabinet 101. By providing the mounting plate 110, the charging device 100 can be secured without opening the equipment cabinet 101 during installation, facilitating the installation of the charging device 100.

[0067] In some embodiments, refer to Figure 3 The charging device 100 also includes a display screen 111, which is fixed to the second cabinet panel 1012. The display area of ​​the display screen 111 is exposed outside the equipment cabinet 101; for example, the display area of ​​the display screen 111 is exposed outside the equipment cabinet 101 through an opening in the second cabinet panel 1012. The exposed display area of ​​the display screen 111 is for personnel to observe the content displayed on the display screen 111 (e.g., the display screen 111 can display billing information, charging status, etc.). After the equipment cabinet 101 is installed, the display screen 111 can be oriented towards personnel so that personnel can observe the content on the display screen 111.

[0068] The display screen 111 is not installed on the first cabinet door 109, which serves as the maintenance door. Instead, the display screen 111 is installed on the second cabinet panel 1012 of the equipment cabinet 101. When maintenance is required on the components inside the equipment cabinet 101, the position of the display screen 111 will not change during the opening of the first cabinet door 109 (the display screen 111 will not move with the first cabinet door 109). In this way, the wires connected to the display screen 111 will not be pulled out due to the movement of the first cabinet door 109, reducing the difficulty for personnel to maintain the equipment cabinet 101.

[0069] In some embodiments, refer to Figure 3The charging device 100 also includes a card reader 112, which is fixed to the second cabinet panel 1012 and exposed outside the equipment cabinet 101. Figure 3 In the illustrated embodiment, the card reader 112 includes an RFID reader 1121 and a POS terminal 1122. The identification area of ​​the RFID reader 1121 is exposed outside the equipment cabinet 101, and the card insertion area and password input area of ​​the POS terminal 1122 are also exposed outside the equipment cabinet 101. In some other embodiments, the second cabinet 1012 may only have the RFID reader 1121 without the POS terminal 1122, or vice versa. In other embodiments, the card reader 112 may also be a card reader other than the two types described above. The card reader 112 is used to identify integrated circuit cards (IC cards), enabling the charging device 100 to identify the user's IC card (bank card, charging card, etc.) through the card reader 112 and perform corresponding charging deductions.

[0070] exist Figure 3 and Figure 4 In the illustrated embodiment, the card reader 112 and the display screen 111 are arranged along the height direction (Z-axis direction) of the equipment cabinet 101. This arrangement reduces the size of the equipment cabinet 101 in the width direction (X-axis direction), thus reducing the floor space occupied by the equipment cabinet 101. In other embodiments, the card reader 112 may also be located in other suitable positions.

[0071] In some embodiments, the display screen 111 and the card reader 112 can be integrated into a single module, thereby improving the integration of the display screen 111 and the card reader 112 and facilitating the overall installation or disassembly of the module formed by the integration of the display screen 111 and the card reader 112. For example, refer to... Figure 3 The charging device 100 also includes a fixing plate 113. The display screen 111 and the card reader 112 are both fixed on the fixing plate 113. Before assembling the charging device 100, the display screen 111 and the card reader 112 can be fixed on the fixing plate 113 in advance, and then the fixing plate 113 can be fixed on the second cabinet plate 1012, so that the fixing plate 113 carries the display screen 111 and the card reader 112 together and is fixed on the second cabinet plate 1012, thereby improving the assembly efficiency of the charging device 100.

[0072] In addition, refer to Figure 3 The charging device 100 also includes multiple charging connectors 105, for example, in Figure 3 and Figure 4In the illustrated embodiment, two charging connectors 105 are provided, and multiple charging connectors 105 are located outside the equipment cabinet 101 and used to connect to the device to be charged. When the multiple charging connectors 105 are not in use, they can be placed on the equipment cabinet 101. For example, the charging device 100 also includes multiple charging gun holders 114. Figure 3 and Figure 4 In the illustrated embodiment, two gun holders 114 are provided and fixed on the second cabinet panel 1012. The two gun holders 114 are arranged along the width direction (X-axis direction) of the equipment cabinet 101. Each gun holder 114 is used for the insertion of the corresponding charging connector 105. That is, when the charging connector 105 is not in use, the charging connector 105 can be inserted into the corresponding gun holder 114.

[0073] Among them, Figure 3 In the illustrated embodiment, multiple gun holders 114 are fixed to the second cabinet panel 1012. When the first cabinet door 109 is opened, each gun holder 114 and the charging connector 105 disposed thereon will not move with the movement of the first cabinet door 109.

[0074] In some embodiments, each charging port 114 is provided with a return switch (e.g., a micro switch). When the charging connector 105 is inserted into the corresponding charging port 114, the return switch on the charging port 114 is triggered. When the charging connector 105 is pulled out of the corresponding charging port 114, the return switch on the charging port 114 is released. The charging device 100 can determine whether the charging connector 105 is inserted into the charging port 114 by detecting whether the return switch on the charging port 114 is triggered.

[0075] Furthermore, with the gun mount 114 fixed to the second cabinet panel 1012, the arrangement of the gun mount 114 and the display screen 111 can be configured according to requirements. For example, refer to... Figure 3 The gun holder 114 and the display screen 111 are arranged along the height direction (Z-axis direction) of the equipment cabinet 101, and the gun holder 114 is located below the display screen 111. This arrangement can reduce the size of the equipment cabinet 101 in the width direction (X-axis direction) and reduce the floor space occupied by the equipment cabinet 101.

[0076] Reference Figure 4 The charging equipment 100 also includes a first DC power distribution device 104, which is installed inside the equipment cabinet 101. The first DC power distribution device 104 is mounted on a first cabinet panel 1011. The first DC power distribution device 104 and the display screen 111 are located on different sides of the first opening 1013. After opening the first cabinet door 109, maintenance of the display screen 111 can be performed facing the second cabinet panel 1012, and maintenance of the first DC power distribution device 104 can be performed facing the first cabinet panel 1011, thus improving the efficiency of personnel maintenance.

[0077] Figure 5 An exemplary diagram illustrates the structure of a first DC power distribution device 104, with reference to... Figure 4 and Figure 5 The first DC power distribution device 104 includes a plurality of first switching devices 1041, which are located inside the equipment cabinet 101 and fixed on the first cabinet plate 1011. The plurality of first switching devices 1041 are arranged along the width direction (X-axis direction) of the equipment cabinet 101.

[0078] Reference Figure 4 and Figure 5 In order to reduce the space occupied by multiple first switching devices 1041 in the width direction of the equipment cabinet 101, two adjacent first switching devices 1041 can be staggered in the height direction (Z-axis direction) of the equipment cabinet 101, that is, two adjacent first switching devices 1041 can have a height difference.

[0079] In some embodiments, refer to Figure 4 The first DC power distribution device 104 also includes a plurality of input metal busbars 1042 (e.g., copper busbars or aluminum busbars) and a plurality of output metal busbars 1043 (e.g., copper busbars or aluminum busbars). Each input metal busbar 1042 is electrically connected to the input terminal of the corresponding first switching device 1041, and each output metal busbar 1043 is electrically connected to the output terminal of the corresponding first switching device 1041 (protection devices and other structures may also be provided between the output metal busbar 1043 and the first switching device 1041).

[0080] In some embodiments, refer to Figure 4 The first DC power distribution device 104 may further include multiple protection devices 1044, wherein the protection devices 1044 may be fuses or surge protectors, etc., and the protection devices 1044 are connected to the input busbar 1042 or to the output busbar 1043. For example, refer to Figure 5 When the protection device 1044 is a fuse, it is fixedly connected between the output terminal of the first switching device 1041 and the output busbar 1043. Alternatively, when the protection device 1044 is a surge protector, its input terminal is electrically connected to the input busbar 1042 via a wire, or to the output busbar 1043 via a wire. Furthermore, the output terminal of the protection device 1044 is grounded. In the event of a surge current or voltage in the circuit, the protection device 1044 shunts the current flowing through the input busbar 1042 or the output busbar 1043, thereby reducing the risk of surge damage to other equipment in the power circuit.

[0081] The multiple devices or components included in the first DC power distribution device 104 (e.g., the first switching device 1041, the protection device 1044, the input metal busbar 1042, the output metal busbar 1043, etc.) can be installed individually on the first cabinet plate 1011, or they can be integrated and installed uniformly on the first cabinet plate 1011, so that the integration of the first DC power distribution device 104 in the equipment cabinet 101 is higher, which greatly improves the installation efficiency and subsequent maintenance efficiency of the charging equipment 100.

[0082] For example, during the installation of the first DC power distribution device 104, it can be assembled independently first. That is, the first switching device 1041, the protection device 1044, the input metal busbar 1042, and the output metal busbar 1043 are all fixed on an independent mounting base. Then, the mounting base is installed on the first cabinet panel 1011. In this way, the first DC power distribution device 104 can be installed as a whole on the first cabinet panel 1011. During maintenance of the first DC power distribution device 104, it can be completely disassembled and replaced by removing the mounting base.

[0083] To connect the first switching device 1041 to the charging connector 105, refer to Figure 4 and Figure 5 The charging device 100 also includes multiple cables 106, wherein the first cabinet panel 1011 has outlet holes 1015 through which the multiple cables 106 pass.

[0084] A portion of each cable 106 is located within the equipment cabinet 101 and is electrically connected to the output terminal of at least one first switching device 1041, for example, referring to Figure 5 Each cable 106 has its positive wire 1061 and negative wire 1062 electrically connected to the output terminal of a first switching device 1041. In the case where the first DC power distribution device 104 includes multiple output metal busbars 1043, each cable 106's positive wire 1061 and negative wire 1062 are connected to one output metal busbar 1043. Another portion of each cable 106 is located outside the equipment cabinet 101 and connected to a corresponding charging connector 105.

[0085] The input terminal of the first switching device 1041 is electrically connected to the power supply 200, for example, referring to... Figure 5When the first DC power distribution device 104 includes multiple input metal busbars 1042, the power supply 200 is electrically connected to the input metal busbars 1042. After power conversion, the current provided by the power supply 200 is delivered to the first switching device 1041 through the input metal busbars 1042. When the first switching device 1041 is closed, the first switching device 1041 allows current to be output from the output terminal of the first switching device 1041. The current output from the output terminal of the first switching device 1041 flows through the output metal busbar 1043 to the cable 106, and is delivered to the corresponding charging connector 105 through the cable 106. Then, the charging connector 105 is used to charge the device to be charged.

[0086] Both the first switching device 1041 and the cable outlet 1015 are located on the first cabinet plate 1011, allowing the cable 106 to exit nearby and shortening its length inside the equipment cabinet 101. Furthermore, the outlet 1015 is positioned above the first switching device 1041, allowing the cable 106 to extend from a higher position within the equipment cabinet 101, effectively distributing the weight of the cable 106 and making it easier and more convenient for users to operate the charging connector 105.

[0087] Furthermore, in some embodiments, the charging device 100 also includes a first control board 115. Figure 6 An exemplary structure of a first control board 115 is shown, with reference to Figure 6 The first control board 115 is a circuit board inside the equipment cabinet 101 that performs control functions. For example, the first control board 115 can control the on / off state of the first switching device 1041, etc.

[0088] Reference Figure 6 The first control board 115 is fixed inside the equipment cabinet 101 and located on the side of the plurality of first switching devices 1041 facing away from the first cabinet door 109. That is, when personnel open the first cabinet door 109 and face the first opening 1013, the first control board 115 is located behind the plurality of first switching devices 1041. Furthermore, one side of the first control board 115 faces the first cabinet door 109. By positioning the first control board 115 on the side of the first switching devices 1041 facing away from the first cabinet door 109, the interference caused by the first control board 115 to the maintenance of the first switching devices 1041 is reduced when the first cabinet door 109 is opened for maintenance. Moreover, the distance between the first control board 115 and the first cabinet door 109 also reduces the possibility of damage to the first control board 115 during maintenance of other devices inside the equipment cabinet 101 (other devices besides the first control board 115), thus protecting the circuit board.

[0089] The first control panel 115 can be fixed inside the equipment cabinet 101 in any suitable manner. For example, the first control panel 115 can be bolted to the first cabinet panel 1011 near its edge, or bolted to the first cabinet panel 1011 near its edge of the second cabinet panel 1012. Alternatively, the first control panel 115 can be fixed to a bracket, and the bracket can be fixed to the first cabinet panel 1011 and the second cabinet panel 1012. Yet another example is fixing the first control panel 115 to the top of the equipment cabinet 101.

[0090] Since the multiple first switching devices 1041 are arranged along the width direction of the equipment cabinet 101, they occupy a large space in the width direction of the equipment cabinet 101. In the case where the charging equipment 100 includes the first control board 115, refer back to the previous section. Figure 4 This positions the first control board 115 above the cable outlet 1015. This causes the first control board 115 to be staggered from the multiple first switching devices 1041, reducing the size of the equipment cabinet 101 in its width direction, i.e., reducing the width of the equipment cabinet 101.

[0091] Furthermore, the first control board 115 is staggered with the multiple first switching devices 1041, ensuring that the multiple first switching devices 1041 do not obstruct the first control board 115, and the portion of the cable 106 located inside the equipment cabinet 101 does not significantly obstruct the first control board 115. After opening the first cabinet door 109, the first control board 115 can be inspected and maintained without disassembling the first switching devices 1041 or the cable 106, facilitating the maintenance of the first control board 115.

[0092] In the case where the charging device 100 includes a first control board 115, refer to Figure 6 Multiple electronic components 1151 (including controllers or control chips) on the first control board 115 face the first cabinet door 109. When maintenance of the first control board 115 is required, after opening the first cabinet door 109, the multiple electronic components 1151 on the first control board 115 face the personnel, making it convenient for personnel to maintain the electronic components 1151 on the first control board 115.

[0093] In some embodiments, refer to Figure 6The charging equipment 100 also includes a second control board 116, which is also a circuit board within the equipment cabinet 101 that performs control functions. For example, the second control board 116 can be connected to a ring network; for example, the second control board 116 can control the display content of the display screen 111; for example, the second control board 116 can control the card reader 112, and so on. The second control board 116 is fixed to the second cabinet panel 1012, and one side of the second control board 116 faces the first cabinet panel 1011, thus spacing the second control board 116 from the first DC power distribution device 104 and reducing the possibility of interference. After opening the first cabinet door 109, the first cabinet panel 1011 allows for maintenance of multiple first switching devices 1041, and the second cabinet panel 1012 allows for maintenance of the second control board 116, which is beneficial for the maintenance of the charging equipment 100.

[0094] Furthermore, when the charging device 100 also includes a display screen 111, the second control board 116 is positioned above the display screen 111. This higher position of the second control board 116 reduces the risk of water immersion should water enter the charging device 100. Additionally, when both the first control board 115 and the second control board 116 are fixed inside the equipment cabinet 101, since the first control board 115 is higher than the cable outlet 1015 (the first control board 115 is higher), setting the second control board 116 higher as well allows it to be closer to the first control board 115, facilitating the connection between the first and second control boards via electronic wires.

[0095] It should be noted that the charging device 100 may include only the first control board 115 and omit the second control board 116. In this embodiment, the first control board 115 also possesses the functions of the second control board 116. Alternatively, the charging device 100 may include only the second control board 116 and omit the first control board 115. In this embodiment, the second control board 116 also possesses the functions of the first control board 115. The charging device 100 may also include both the first control board 115 and the second control board 116. It is understood that in this embodiment, the first control board 115 and the second control board 116 are two circuit boards with different functions.

[0096] In some embodiments, refer to Figure 5The charging device 100 may also include a power supply device 117 (auxiliary power supply), which is electrically connected to the power supply 200. The power supply device 117 is also electrically connected to at least one of the first control board 115 and the second control board 116. The power supply device 117 is used to convert the AC power input from the power supply 200 into DC power to supply power to at least one of the first control board 115 and the second control board 116. That is, the power supply device 117 is a small power conversion device.

[0097] The power supply unit 117 can be fixed in any suitable location, for example, refer to Figure 6 The power supply device 117 is located inside the equipment cabinet 101 and connected to the second cabinet panel 1012. The power supply device 117 can slide relative to the second cabinet panel 1012 in a direction close to or away from the first cabinet door 109. That is, after opening the first cabinet door 109, the power supply device 117 can be pulled out along the width direction (X-axis direction) of the equipment cabinet 101. Any connection structure that enables the power supply device 117 to slide relative to the second cabinet panel 1012 can be used to connect the power supply device 117 and the second cabinet panel 1012.

[0098] exist Figure 6 In the illustrated embodiment, a mounting shell 1171 is fixed on the second cabinet panel 1012. The mounting shell 1171 has a mounting opening 1172 facing the first opening 1013. The power supply device 117 can be inserted into the mounting shell 1171 from the mounting opening 1172 along the width direction (X-axis direction) of the equipment cabinet 101, or the power supply device 117 can be pulled out from the mounting shell 1171 from the mounting opening 1172 along the width direction of the equipment cabinet 101.

[0099] In some other embodiments, the second cabinet panel 1012 is provided with a sliding groove, and the power supply device 117 is provided with a slider. The slider on the power supply device 117 can slide within the sliding groove on the second cabinet panel 1012. Through the cooperation between the slider and the sliding groove, the power supply device 117 and the second cabinet panel 1012 are slidably connected. Setting the power supply device 117 to be able to slide relative to the equipment cabinet 101 facilitates the installation and removal of the power supply device 117.

[0100] After opening the first cabinet door 109, during the process of pulling out the power supply device 117, the power supply device 117 is slid towards or away from the first opening 1013. The first opening 1013 is connected to the outside space. If it is necessary to disassemble the power supply device 117, personnel can pull the power supply device 117 outwards from the first opening 1013 to move it closer to the first opening 1013, and gradually pull the power supply device 117 out of the equipment cabinet 101 to achieve disassembly. If it is necessary to install the power supply device 117, push the power supply device 117 towards the inside of the equipment cabinet 101. After the power supply device 117 is inside the equipment cabinet 101, continue to push the power supply device 117 away from the first opening 1013 to complete the installation of the power supply device 117.

[0101] Reference Figure 6 Since multiple first switching devices 1041 on the first cabinet panel 1011 need to be connected by cables 106, in this application, the power supply device 117 is set on the second cabinet panel 1012, so that the power supply device 117 can slide relative to the second cabinet panel 1012. This allows the power supply device 117 to be installed and removed using the first opening 1013, and also reduces the impact of the power supply device 117 on the wiring of multiple first switching devices 1041, making the internal layout of the equipment cabinet 101 more reasonable.

[0102] Furthermore, in the embodiment where the charging device 100 includes a display screen 111 and a second control board 116, since the second control board 116 is located above the display screen 111, the power supply device 117 can be positioned below the display screen 111. This arrangement of the second control board 116, display screen 111, and power supply device 117 along the height direction (Z-axis direction) of the equipment cabinet 101 reduces the size of the equipment cabinet 101 in the width direction (X-axis direction), thus reducing the floor space occupied by the equipment cabinet 101. Additionally, positioning the display screen 111 between the second control board 116 and the power supply device 117 allows the display screen 111 to be in a position easily accessible to personnel. If the display screen 111 is located below the second control board 116 and the power supply device 117, its position is too low; if it is located above the second control board 116 and the power supply device 117, its position is too high, both of which are unfavorable for personnel viewing.

[0103] Reference Figure 6 The charging device 100 also includes a second switching device 118 (e.g., an air switch, circuit breaker, contactor, etc.). The input terminal of the second switching device 118 is electrically connected to the power supply 200 via a wire, and the output terminal of the second switching device 118 is electrically connected to the power supply device 117 via a wire. The second switching device 118 can control the on / off state of the circuit between the power supply device 117 and the power supply 200.

[0104] When the charging device 100 also includes a second switching device 118, the second switching device 118 can be fixed on the second cabinet panel 1012, so that the second switching device 118 is located opposite to the plurality of first switching devices 1041, which can reduce the size of the equipment cabinet 101 in the width direction (X-axis direction). Furthermore, the second switching device 118 and the power supply device 117 are arranged along the height direction (Z-axis direction) of the equipment cabinet 101, which not only makes full use of the space below the display screen 111, but also reduces the size of the equipment cabinet 101 in the width direction, making the internal layout of the equipment cabinet 101 more reasonable.

[0105] In some embodiments, refer to Figure 6 In the case where the charging device 100 also includes a terminal block 119, the power supply device 117 is connected to the terminal block 119 via a first electronic wire, and the terminal block 119 is connected to devices such as the display screen 111 and the control board (first control board 115 and / or second control board 116) via multiple second electronic wires. The power supply device 117 provides power to the display screen 111, the control board and other devices, and the terminal block 119 serves as a transfer device.

[0106] exist Figure 6 In the illustrated embodiment, the terminal block 119 and the power supply device 117 are arranged along the height direction (Z-axis direction) of the equipment cabinet 101, reducing the size of the equipment cabinet 101 in the width direction. When the charging device 100 also includes a second switching device 118, the terminal block 119 and the second switching device 118 are arranged along the width direction (X-axis direction) of the equipment cabinet 101. This saves space in the height direction of the equipment cabinet 101, making the positions of the terminal block 119, the second switching device 118, and the power supply device 117 more compact. In some embodiments, both the terminal block 119 and the second switching device 118 are positioned above the power supply device 117, placing them at a higher position. This reduces the risk of the terminal block 119 and the second switching device 118 getting wet if water enters the charging device 100.

[0107] In some embodiments, the charging device 100 also has another access door; for example, the charging device 100 further includes a second cabinet door 120. Figure 7 An exemplary structure of a second cabinet door 120 is shown. (Refer to...) Figure 7The equipment cabinet 101 has a second opening 1014 communicating with its internal space. The second opening 1014 is located between the first cabinet panel 1011 and the second cabinet panel 1012. The second opening 1014 and the first opening 1013 are arranged along the width direction (X-axis direction) of the equipment cabinet 101. The second cabinet door 120 is located between the first cabinet panel 1011 and the second cabinet panel 1012. Both the first cabinet door 109 and the second cabinet door 120 are in the closed state, and the first cabinet door 109 and the second cabinet door 120 are arranged along the width direction of the equipment cabinet 101.

[0108] exist Figure 7 In the illustrated embodiment, the second cabinet door 120 is connected to the second cabinet panel 1012. In other embodiments, the second cabinet door 120 is connected to the first cabinet panel 1011. The second cabinet door 120 is movable relative to the equipment cabinet 101 (e.g., the second cabinet door 120 is connected to the equipment cabinet 101 via a hinge). Furthermore, the second cabinet door 120 is used to open or close the equipment cabinet 101. For example, when the second cabinet door 120 closes the second opening 1014, the second cabinet door 120 also closes the equipment cabinet 101; when the second cabinet door 120 opens the second opening 1014, the second cabinet door 120 also opens the equipment cabinet 101.

[0109] When the charging device 100 includes a first control board 115, the first control board 115 is located on the side of the plurality of first switching devices 1041 facing the second cabinet door 120. That is, the first control board 115 is relatively close to the second cabinet door 120. If it is necessary to disassemble the first control board 115, the second cabinet door 120 can be opened to expose the first control board 115, making it convenient for personnel to disassemble the first control board 115. Similarly, if it is necessary to install the first control board 115, the second cabinet door 120 can be opened and the first control board 115 can be installed through the second opening 1014.

[0110] In some embodiments, the charging device 100 further includes a plurality of electricity meters 121, as shown in the figure. Figure 7 In the case where the charging equipment 100 also includes a first cabinet door 109 and a second cabinet door 120, a power meter 121 is fixed on each of the first cabinet door 109 and the second cabinet door 120. The display area of ​​the power meter 121 on the first cabinet door 109 is exposed to the outside of the equipment cabinet 101 through the window 1211 on the first cabinet door 109, and the display area of ​​the power meter 121 on the second cabinet door 120 is exposed to the outside of the equipment cabinet 101 through the window 1211 on the second cabinet door 120, so that personnel can observe the value of the power meter 121.

[0111] Each meter 121 can display the charging data of the corresponding charging connector 105, thereby measuring the amount of charge received by the charging device 100. The meter 121 can detect the charging data of the charging connector 105 using any suitable method. For example, the first DC power distribution device 104 of the charging device 100 also includes a shunt, which can be a metal busbar (e.g., copper or aluminum). The shunt is fixed to the input metal busbar 1042 or the output metal busbar 1043 and is electrically connected to the meter 121. By detecting the current flowing through the shunt, the meter 121 can determine the magnitude of the current flowing through the input metal busbar 1042 or the output metal busbar 1043, thus detecting the charging data of the corresponding charging connector 105.

[0112] Among them, reference Figure 7 The cable outlet 1015 includes a first cable outlet 1016 and a second cable outlet 1017 arranged along the width direction (X-axis direction) of the equipment cabinet 101. The first cable outlet 1016 is located on the side of the second cable outlet 1017 facing the first cabinet door 109. Multiple charging connectors 105 include a first charging connector 1051 and a second charging connector 1052. The first charging connector 1051 is electrically connected to the cable 106 passing through the first cable outlet 1016, and the second charging connector 1052 is electrically connected to the cable 106 passing through the second cable outlet 1017. That is, personnel will stand on different sides of the equipment cabinet 101 to use the first charging connector 1051 and the second charging connector 1052. For example, when using the first charging connector 1051, personnel will stand close to the first cabinet door 109; when using the second charging connector 1052, personnel will stand close to the second cabinet door 109.

[0113] Different meters 121 are installed on the first cabinet door 109 and the second cabinet door 120. The meter 121 on the first cabinet door 109 displays the charging data of the first charging connector 1051, and the meter 121 on the second cabinet door 120 displays the charging data of the second charging connector 1052. When a person uses the first charging connector 1051 to charge the device, the meter 121 on the first cabinet door 109 can reflect the charging status of the first charging connector 1051. Similarly, when a person uses the second charging connector 1052 to charge the device, the meter 121 on the second cabinet door 120 can reflect the charging status of the second charging connector 1052. With this design, the meters 121 located on different sides of the equipment cabinet 101 facilitate the observation of charging values ​​when a person uses different charging connectors 105.

[0114] In addition, since both the first cabinet door 109 and the second cabinet door 120 are adjacent to the second cabinet panel 1012 where the display screen 111 is located, it is convenient for personnel to compare the data displayed on the display screen 111 and the data displayed on the display screen 121 by installing the electricity meter 121 on the first cabinet door 109 and the second cabinet door 120.

[0115] In some embodiments, the charging device 100 further includes a functional component 122 for performing a specific function. Figure 8 The structure of functional component 122 is shown exemplarily, with reference to Figure 8 The functional component 122 includes a deflector fan 1221, which can be positioned at any suitable location, for example, fixed to the first cabinet door 109. Furthermore, the deflector fan 1221 is used to blow air into the equipment cabinet 101; for example, it can blow air into areas of the equipment cabinet 101 that are experiencing severe heat generation, thereby eliminating localized hot spots and making the temperature inside the equipment cabinet 101 more uniform.

[0116] Among them, reference Figure 8 The deflector fan 1221 may include a first deflector fan 1222, which is located inside the equipment cabinet 101 and fixed to the first cabinet door 109. After the first cabinet door 109 is closed, the air outlet of the first deflector fan 1222 faces the inside of the equipment cabinet 101. The first deflector fan 1222 blows the heat inside the equipment cabinet 101 onto the equipment cabinet 101, and then heat dissipation is achieved through heat exchange between the equipment cabinet 101 and the outside air. In addition, in some embodiments, since the output metal busbar 1043 also generates significant heat due to prolonged airflow, the air outlet of the first deflector fan 1222 can blow air towards the output metal busbar 1043, blowing the heat from the output metal busbar 1043 onto the equipment cabinet 101, and then heat dissipation is achieved through heat exchange between the equipment cabinet 101 and the outside air.

[0117] In some embodiments, refer to Figure 8 The deflector fan 1221 may also include a second deflector fan 1223. The second deflector fan 1223 is located inside the equipment cabinet 101 and fixed to the first cabinet door 109. The air outlet of the second deflector fan 1223 faces the first switching device 1041, or the air outlet of the second deflector fan 1223 faces the input metal busbar 1042. The input metal busbar 1042 and the first switching device 1041 generate significant heat due to prolonged current flow. By blowing air onto the input metal busbar 1042 or the first switching device 1041 through the second deflector fan 1223, the heat on the input metal busbar 1042 and the first switching device 1041 is transferred to the equipment cabinet 101, and then heat is dissipated through heat exchange between the equipment cabinet 101 and the outside air.

[0118] exist Figure 8In the illustrated embodiment, the electricity meter 121 on the first cabinet door 109 is located above the first deflector fan 1222 and the second deflector fan 1223. In some other embodiments, the electricity meter 121 on the first cabinet door 109 is located between the first deflector fan 1222 and the second deflector fan 1223, or the electricity meter 121 on the first cabinet door 109 is located below the first deflector fan 1222 and the second deflector fan 1223.

[0119] In some other embodiments, the equipment cabinet 101 may contain only one deflector fan 1221 (e.g., only the first deflector fan 1222, or only the second deflector fan 1223). In some other embodiments, the equipment cabinet 101 may not contain a deflector fan 1221.

[0120] In some other embodiments, when the equipment cabinet 101 is equipped with a second cabinet door 120, the deflector fan 1221 can be fixed to the second cabinet door 120, and the deflector fan 1221 is used to blow air into the equipment cabinet 101.

[0121] Reference Figure 8 The functional component 122 may also include a heating device 1224, which is used to heat the internal space of the equipment cabinet 101 when the ambient temperature is low, so that some devices or components that are not resistant to low temperatures (e.g., the display screen 111) can operate normally. The heating device 1224 can be any device capable of generating heat. For example, the heating device 1224 includes a resistance wire and a fan, and the fan blows the heat generated by the resistance wire into the equipment cabinet 101.

[0122] The heating device 1224 can be installed in any suitable location within the equipment cabinet 101. Figure 8 In the illustrated embodiment, the heating device 1224 is fixed to the first cabinet door 109, and the heating device 1224 is located on the side of the second deflector fan 1223 opposite to the first deflector fan 1222. In some other embodiments, the heating device 1224 is located between the first deflector fan 1222 and the second deflector fan 1223. In some other embodiments, the charging device 100 may not include the heating device 1224.

[0123] In some other embodiments, when the equipment cabinet 101 is equipped with a second cabinet door 120, the heating device 1224 can be fixed to the second cabinet door 120.

[0124] In some embodiments, refer to Figure 8The functional component 122 may also include an emergency stop button 1225. In the event of an emergency during the use of the charging device 100, the emergency stop button 1225 can control the first switching device 1041 to disconnect the circuit between the power supply 200 and the charging connector 105. The emergency stop button 1225 can be located in any suitable position. Figure 8 In the illustrated embodiment, the emergency stop button 1225 is fixed to the first cabinet door 109, and the emergency stop button 1225 is located between the first spoiler fan 1222 and the second spoiler fan 1223. In some other embodiments, the emergency stop button 1225 is located above (or below) the first spoiler fan 1222 and the second spoiler fan 1223.

[0125] In some other embodiments, when the equipment cabinet 101 is equipped with a second cabinet door 120, the emergency stop button 1225 can also be fixed to the second cabinet door 120. For example, Figure 9 An exemplary structure of another functional component 122 is shown, with reference to Figure 9 The emergency stop button 1225, which is part of the functional component 122, is fixed to the second cabinet door 120. In some other embodiments, the charging device 100 may not include the emergency stop button 1225.

[0126] When personnel need to inspect the internal devices of the equipment cabinet 101, after opening the first cabinet door 109, the devices on the first cabinet door 109 will inevitably collide with personnel or maintenance tools. The heating device 1224, the turbulence fan 1221, or the emergency stop button 1225 are all functional components 122 that are not easily damaged. By placing the functional components 122 (including at least one of the heating device 1224, the turbulence fan 1221, or the emergency stop button 1225) on the first cabinet door 109, more space is provided on the first cabinet panel 1011 and the second cabinet panel 1012 for the installation of easily damaged devices. After opening the first cabinet door 109, some easily damaged devices (e.g., functional components 122) are exposed with the first cabinet door 109, while some easily damaged devices remain inside the equipment cabinet 101, making the layout of the internal devices of the equipment cabinet 101 more reasonable and extending the overall lifespan of the charging equipment 100.

[0127] Furthermore, in the event of water accumulation at the top of the first cabinet door 109, a water-blocking structure can also be installed on the first cabinet door 109, for example, referring to... Figure 8 The charging device 100 may also include a baffle 125, which is fixed to the first cabinet door 109 and extends toward the interior space of the equipment cabinet 101 (when the first cabinet door 109 is closed). When a functional component 122 (including at least one of a heating device 1224, a turbulence fan 1221, or an emergency stop button 1225) is provided on the first cabinet door 109, the baffle 125 is located above the functional component 122. For example, in Figure 8 In the illustrated embodiment, a heating device 1224, an electric meter 121, a deflector fan 1221, and an emergency stop button 1225 are disposed on the first cabinet door 109, and all of these are located below the baffle 125. When the first cabinet door 109 is opened, the presence of the baffle 125 can partially block and prevent liquid dripping from the top of the first cabinet door 109, reducing the possibility of short circuits between the multiple devices on the first cabinet door 109 caused by the dripping liquid.

[0128] In other embodiments, the charging device 100 also includes a structure capable of shielding the first switching device 1041; for example, the charging device 100 also includes a protective cover 123. Figure 10 An exemplary structure of a protective shield 123 is shown, with reference to Figure 10 The protective cover 123 is fixed inside the equipment cabinet 101, and the protective cover 123 is located on multiple first switching devices 1041. Figure 10 The protective cover 123 (covered by a protective shield 123) faces the first cabinet door 109 and is used to shield the first DC power distribution device 104 (including multiple first switching devices 1041). That is, after the first cabinet door 109 is opened, the protective cover 123 can shield the first DC power distribution device 104, so that the first DC power distribution device 104 is not exposed, which can protect both personnel and the first DC power distribution device 104.

[0129] The protective cover 123 can be fixed inside the equipment cabinet 101 by any suitable means. Figure 10 In the illustrated embodiment, the protective cover 123 is fixedly connected to the first cabinet panel 1011 near its edge (e.g., by bolts), and the protective cover 123 is fixedly connected to the second cabinet panel 1012 near its edge (e.g., by bolts). In other embodiments, the protective cover 123 is fixed (e.g., by bolts) to the first cabinet panel 1011, and is not connected to the second cabinet panel 1012; or, the protective cover 123 is fixed (e.g., by bolts) to the second cabinet panel 1012, and is not connected to the first cabinet panel 1011. When maintenance of the first switching device 1041 is required, the protective cover 123 can be removed.

[0130] When the charging device 100 also includes a functional component 122, the functional component 122 is fixed to the first cabinet door 109, and the protective cover 123 is provided with at least one clearance groove 1232 for avoiding the functional component 122. In addition, when the functional component 122 includes a deflector fan 1221, the protective cover 123 is also provided with an air vent 1231, which faces the air outlet of the deflector fan 1221, and the air blown out by the deflector fan 1221 can pass through the air vent 1231.

[0131] In the case where the charging equipment 100 also includes a second cabinet door 120, a protective cover 123 can also be provided on the side of the multiple first switching devices 1041 facing the second cabinet door 120. That is, when the second cabinet door 120 is opened, the protective cover 123 blocks the first DC power distribution device 104, and the protective cover 123 needs to be removed in order to inspect the first DC power distribution device 104 through the second opening 1014.

[0132] In some embodiments, refer to Figure 10 The charging device 100 may also include an indicator light 124, which is located above the display screen 111. The indicator light 124 is used to display the charging status of the charging device 100. For example, the indicator light 124 expresses information such as charging, standby, fault, reservation, and amount of charge through changes in color or shape.

[0133] also, Figure 11 An exemplary view shows the location of another gun mount 114, see reference. Figure 11 In the case where the charging device 100 includes a first cabinet door 109 and a second cabinet door 120, one gun holder 114 is fixed on the first cabinet door 109 and the other gun holder 114 is fixed on the second cabinet door 120.

[0134] In some other embodiments, the charging device 100 may also include a cable management device fixed to the top of the device cabinet 101. The cable management device is capable of suspending multiple cables 106 and sharing part of the weight of the cables 106, thereby making it easier for the user to use the charging connector 105.

[0135] In some embodiments, the charging device 100 is a naturally cooled charging pile, that is, the device cabinet 101 does not have a water tank (for containing coolant), a drive pump (for driving coolant), a cooling pipe (for supplying coolant flow and cooling cable 106) or other structures inside.

[0136] It is understood that in this application, the width direction, thickness direction, and height direction of the equipment cabinet 101 are all perpendicular to each other, and the X-axis, Y-axis, and Z-axis in the coordinate system are all perpendicular to each other.

[0137] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
