Description

Technical Field

[0001] This application relates to the field of charging facility technology, and in particular to a charging device. Background Technology

[0002] With technological advancements, the market share of new energy vehicles is continuously increasing. Simultaneously, the demand for charging equipment from new energy vehicle owners is growing, leading to a corresponding increase in the availability of charging facilities. New energy vehicle owners require public charging stations when out and about, and private charging stations at home. Therefore, with the proliferation of charging equipment on the market, regular safety maintenance of these devices by consumers and maintenance personnel becomes particularly important.

[0003] To comply with safety standards, it is now common practice for charging equipment to be equipped with circuit breakers and electricity meters. Charging equipment includes DC charging piles and AC charging piles. DC charging piles are larger, thus having sufficient space to install circuit breakers and electricity meters, and are easy to maintain. However, AC charging piles are generally smaller, with limited space for their internal electronic components. Operating the circuit breaker and electricity meter often requires removing the protective casing, which can easily lead to accidental contact with the control board and wiring, posing a safety hazard. Furthermore, the frequent disassembly and reassembly of the protective casing for use and maintenance is also more cumbersome. Utility Model Content

[0004] Therefore, it is necessary to provide a charging device that addresses the problems of inconvenient maintenance and accidental activation of current charging equipment.

[0005] This application provides a charging device, including a first housing structure and a second housing structure. The first housing structure and the second housing structure are independently arranged. The first housing structure and the second housing structure separate the internal space of the charging device into a first functional area and a second functional area. The first functional area is located inside the first housing structure, and the second functional area is located inside the second housing structure. A control component is provided in the first functional area, and a protection component and a metering component are provided in the second functional area. The control component is electrically connected to the protection component and the metering component.

[0006] In one embodiment, the first housing structure and the second housing structure have a first through hole corresponding to the metering component, and the first housing structure and the second housing structure have a second through hole corresponding to the component. An external power supply is connected to the first functional area via a cable. The cable in the first functional area is adapted to pass through the first through hole to connect to the second functional area. The cable is connected in series with the protection component and the metering component in the second functional area, and is output through the output terminal of the metering component. The output cable is connected back to the first functional area through the second through hole.

[0007] In one embodiment, the control component includes a first terminal block and a second terminal block, the input terminal of the first terminal block being electrically connected to the external power supply via the cable, the output terminal of the first terminal block being electrically connected to the input terminal of the protection component in the second functional area, the output terminal of the protection component being electrically connected to the input terminal of the metering component, and the output terminal of the metering component being electrically connected to the input terminal of the second terminal block.

[0008] In one embodiment, the control component further includes a charging control motherboard, which has plug-in terminals that are plugged into the second terminal block.

[0009] In one embodiment, the charging device has a first wiring structure, which includes a charging cable and a charging head. The output end of the charging cable is electrically connected to the charging head, and the input end of the charging cable is electrically connected to the output end of the second terminal block.

[0010] In one embodiment, the charging device has a second wiring structure, which includes a plurality of conductive contacts forming a conductive contact group, the conductive contact group being electrically connected to the output terminal of the second terminal block.

[0011] In one embodiment, the first housing structure includes a first back plate, a bottom shell, a middle cover, and a top cover. The bottom shell is disposed on the first back plate, the middle cover is disposed on the bottom shell, and the top cover is disposed on the middle cover. A first sealing element is provided at the connection between the first back plate and the bottom shell, a second sealing element is provided at the connection between the middle cover and the bottom shell, and a third sealing element is provided at the connection between the top cover and the middle cover.

[0012] In one embodiment, the middle cover has a contact housing corresponding to the conductive contact group, the conductive contact group is inserted into the contact housing, the upper cover has an insertion hole corresponding to the conductive contact group, and the upper cover is rotatably provided with a baffle, the baffle is adapted to flip to open or close the insertion hole.

[0013] In one embodiment, the second housing structure includes a second back plate, an outer shell, and a cover plate. The outer shell is connected to the second back plate and is disposed around the periphery of the second functional area. The cover plate is movably disposed on the outer shell. A fourth sealing element is provided at the connection between the second back plate and the outer shell, and a fifth sealing element is provided at the connection between the cover plate and the outer shell.

[0014] In one embodiment, the metering component has a viewing panel, the housing has a viewing window corresponding to the viewing panel, and the housing has an operation window corresponding to the protective component.

[0015] In the aforementioned charging equipment, the internal space is divided into a first functional area and a second functional area by a first housing structure and a second housing structure. The first functional area contains control components, while the other functional area contains protection components and metering components. Corresponding electrical connection lines are provided within the first and second housing structures. Since the first and second housing structures are independent of each other, and the first functional area within the first housing structure and the second functional area within the second housing structure are also independent of each other, maintenance only requires disassembling or reassembling either the first or second housing structure. Therefore, only the circuits within the first or second housing structure are affected, while the circuits in the functional areas that do not require maintenance will not experience accidental touches or other operational errors. This effectively ensures maintenance safety within the compact structural layout of the charging pile and reduces potential safety hazards. Attached Figure Description

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] This application provides a charging device, including a first housing structure 7 and a second housing structure 8 that are independent of each other. The first housing structure 7 and the second housing structure 8 divide the internal space of the charging device into a first functional area 1 and a second functional area 2. The first functional area 1 contains an independently installed control component, while the second functional area 2 contains a protection component and a metering component. In this embodiment, the protection component can be a circuit breaker, and the metering component can be an electricity meter. Furthermore, the first functional area 1 and the second functional area 2 are independent of each other, and the multiple circuit components in the first functional area 1 and the second functional area 2 are connected only by cables. During maintenance, only the circuit components in the functional area requiring maintenance will be affected, while the circuit components and wiring in other functional areas will not be affected by accidental contact or other operational errors, thus effectively ensuring the safety of maintenance.

[0030] See Figure 1 and Figure 5 The first housing structure 7 and the second housing structure 8 have first through holes 13 corresponding to the metering components, and second through holes 14 corresponding to the protection components. Multiple wiring ports 6 are provided on the upper or lower side of the first housing structure 7. When an external power supply is connected to the first functional area 1 within the first housing structure 7, it can be connected via either an upper or lower wiring method. After the cable passes through the wiring port to connect to the external power supply, the external power supply is connected to the control component located in the first functional area 1. Then, the cable passes through the first through hole 13 to connect to the second functional area 2, and the protection component and metering component in the second functional area are connected in series. Finally, the output of the metering component is connected back to the control component in the first functional area 1 to form a loop.

[0031] When maintenance is required, maintenance personnel can open the first housing structure 7 or the second housing structure 8 to maintain and repair the circuit components located in the corresponding first functional area 1 or second functional area 2. During maintenance, there is no interference between different functional areas, thus preventing accidental activation and other malfunctions, effectively ensuring operational safety. Furthermore, in this embodiment, the first housing structure 7 and the second housing structure 8 divide the internal space of the charging device into the first functional area 1 and the second functional area 2, but this does not mean it can only be divided into two functional areas; it could also be divided into three, four, or other functional areas.

[0032] See Figure 4Specifically, the control component includes a first terminal block 4 and a second terminal block 5 disposed in the first functional area 1. The input terminal of the first terminal block 4 can be electrically connected to an external power supply through the wiring port 3. After the first terminal block 4 is connected to the external power supply, its output terminal is connected to the input terminal of the protection component in the second functional area 2. Then, it is electrically connected to the input terminal of the metering component through the output terminal of the protection component, and then connected back to the input terminal of the second terminal block 5 in the first functional area 1 through the output terminal of the metering component. That is, the area is equipped with a first terminal block 4 and a second terminal block 5. After the first terminal block 4 is directly connected to the external power supply through the wiring port 3, the following power supply circuit is formed: First, the external power supply flows through the first terminal block 4 and then sequentially through the metering component and the protection component in the second functional area 2. After the metering component performs energy metering, the energy is fed back to the second terminal block 5 in the first functional area 1 through the feedback circuit.

[0033] More specifically, the control assembly also includes a charging control motherboard 6, which has plug-in terminals and is connected to the second terminal block 5 via the plug-in terminals.

[0034] In addition, the charging device has two wiring methods, which are implemented through a first wiring structure and a second wiring structure, respectively.

[0035] When the first wiring structure is used for charging, the first wiring structure is a gun wire structure, which includes a gun wire and a gun head. During charging, the input end of the gun wire is directly connected to the second terminal block 5, and the output end of the gun wire is electrically connected to the gun head, thereby enabling direct output of electrical energy through the gun wire and gun head.

[0036] When using the second wiring structure for charging, the second wiring structure is a gun holder structure, which includes multiple conductive contacts. In this embodiment, there are seven conductive contacts, which form a conductive contact group 9 to output AC power. The conductive contact group 9 is electrically connected to the output terminal of the second terminal block 5 to realize the output of electrical energy through the conductive contact group 9. In use, since the gun holder structure only provides a plug-in port, the user needs to use the built-in double-ended charging cable (with charging gun heads at both ends) to connect the plug-in port of the charging device and the charging port of the vehicle for charging.

[0037] See Figure 2The first housing structure 7 includes a bottom shell 71, a middle cover 72, an upper cover 73, and a first back plate 74. The bottom shell 71 covers the first back plate 74, the middle cover 72 covers the bottom shell 71, and the upper cover 73 covers the middle cover 72. A first sealing element is provided at the connection between the first back plate 74 and the bottom shell 71, a second sealing element is provided at the connection between the bottom shell 71 and the middle cover 72, and a third sealing element is suitable for the connection between the middle cover 72 and the upper cover 73. Thus, the first, second, and third sealing elements can restrict the entry of external debris into the first functional area 1. The first, second, and third sealing elements can be configured as waterproof sealing rings (not shown in the figure). The waterproof sealing rings ensure that the internal environment of the charging device remains stable when operating under harsh external conditions, effectively preventing external debris from entering the charging device along the installation gaps and affecting the stability of the electronic components inside the charging device.

[0038] In addition, the charging control motherboard 6 is mounted on the bottom shell 71, and the middle cover 72 is equipped with a display screen 15. The display screen 15 is electrically connected to the charging control motherboard 6. At the same time, a communication version and / or a card-swipe version control module that can be electrically connected to the charging control motherboard 6 are also installed. The communication version control module can wirelessly connect to a mobile terminal to wirelessly control the start and stop of the charging device through the mobile terminal. The card-swipe version control module requires a card swipe to control the start and stop of the charging device.

[0039] Specifically, the middle cover 72 has a contact housing (not shown in the figure) corresponding to the conductive contact group 9. Each conductive contact of the conductive contact group 9 can be inserted into the contact housing. The upper cover 73 has a socket 10 corresponding to the conductive contact group 9. During charging, the dual-head charging gun passes through the socket 10 and connects with the conductive contact group 9 to achieve charging.

[0040] Additionally, a rotatable baffle 11 is provided on the top cover 73, which can be flipped to open or close the socket 10. The baffle 11 can be flipped to either a first or second position. When flipped to the first position, the baffle 11 covers the opening of the socket 10. When flipped to the second position, the baffle 11 is horizontal, providing protection above the socket 10. Furthermore, to further protect charging safety, a waterproof sealing ring 12 is provided between the contact housing on the middle cover 72 and the socket 10 on the top cover 73. Through the cooperation of the waterproof sealing ring and the baffle 11, rainwater can be effectively prevented from flowing into the socket 10 along the outer surface of the top cover 73 during charging in rainy weather, thus avoiding potential safety hazards.

[0041] See Figure 3The second housing structure 8 includes an outer shell 81, a cover plate 82, and a second back plate 83. The outer shell 81 is connected to the second back plate 83, and the outer shell 81 is arranged around the periphery of the second functional area 2. The cover plate 82 is movably covered on the outer shell 81, and a fourth sealing element is provided at the connection between the outer shell 81 and the second back plate 83, and a fifth sealing element is provided at the connection between the cover plate 82 and the outer shell 81. Both the fourth and fifth sealing elements can be set as edge waterproof sealing rings (not shown in the figure), thereby effectively restricting external debris from entering the second functional area 2 through the edge waterproof sealing rings.

[0042] It should be noted that the first backplate 74 and the second backplate 83 can be formed as a whole or as multiple independent structures. Thus, the arrangement of the first housing structure 7 and the second housing structure 8 enables the charging device to have an independent maintenance mechanism. Under this maintenance mechanism, the independent first housing structure 7 and the second housing structure 8 achieve physical isolation of the functional areas within the charging device, ensuring that the control components (first functional area 1) and the protection / metering components (second functional area 2) do not interfere with each other during maintenance operations. This effectively avoids the risk of accidental contact with circuit wiring during operation and also meets the principle of modular design for ease of maintenance.

[0043] See Figure 3 Specifically, a viewing window 811 is provided on the outer casing 81 corresponding to the metering component. Since the metering component has a viewing panel, the viewing panel can be exposed through the viewing window 811, allowing maintenance personnel to observe the power data recorded by the metering component. Additionally, an operation window 812 is provided on the outer casing 81 corresponding to the protection component, allowing operators to directly operate the protection component. Therefore, during routine maintenance, only the cover 82 needs to be opened to operate the protection component and the metering component without further disassembling the first casing structure 7.

[0044] Therefore, through the design of the first housing structure 7 and the second housing structure 8, the safety performance of the internal circuit components and circuits is effectively improved. By independently setting the protection components and metering components in the second housing structure 8, and independently setting the control components in the first housing structure 7, it is possible to quickly and individually disassemble the second housing structure 8 or the first housing structure 7 and quickly cut off the faulty circuit without disassembling the entire charging device. This meets the requirements of electrical safety maintenance and reflects the concept of a reasonable and compact internal electrical layout of the charging device.

[0045] Furthermore, by modularizing the internal structure of the charging equipment, it offers significant advantages in modular maintenance. The physical separation of the first housing structure 7 and the second housing structure 8 enables a modular layout of the control unit and the power unit. This design supports selective maintenance, meeting the technical requirement of modular design to reduce maintenance costs. In addition, this design improves the operational efficiency of maintenance personnel. The independent disassembly of the first housing structure 7 and the second housing structure 8 allows operators to simultaneously perform maintenance work on different functional areas, significantly shortening the maintenance time.
