[0046] See Figure 1 This application illustrates a charging device 100 according to one embodiment, more specifically, the charging device 100 is a charging pile. Depending on actual needs, the charging pile can be any type, such as a floor-mounted charging pile or a wall-mounted charging pile, and can be flexibly selected. After installation, the charging pile can be used to supply power (charge) electrical equipment such as new energy vehicles to meet the range requirements of these devices.

[0047] Please continue reading. Figure 1 , Figure 3 as well as Figures 5 to 7For example, the charging device 100 includes a housing 10, a main board 20, an electrical component 30, and a protective plate 40, with the main board 20 electrically connected to the electrical component 30. The housing 10 is the main structure of the charging device 100 and acts as a carrier, serving to house and integrate the main board 20, the electrical component 30, and the protective plate 40, and providing protection for the main board 20, the electrical component 30, and the protective plate 40.

[0048] The outer shell 10 can be made of any material such as plastic or metal, and the choice can be made flexibly according to actual needs. No specific limitation is made here.

[0049] Please continue reading. Figure 2 and Figure 3 Specifically, the housing 10 has an internal mounting cavity 11, the main board 20 and the electrical components 30 are respectively installed in the mounting cavity 11, and the protective plate 40 is installed in the mounting cavity 11. The protective plate 40 covers at least a portion of the main board 20 and at least a portion of the electrical components 30 along the first direction of the charging device 100, so as to provide shielding protection for the main board 20 and the electrical components 30.

[0050] It should be noted that the charging device 100 in this application is approximately rectangular in shape. The special feature is that the outer periphery of the outer shell 10 is designed with an arc-shaped structure to improve the appearance of the charging device 100 and prevent the sharp corners from accidentally injuring the user.

[0051] Therefore, the first direction of the charging device 100 in this application can refer to the thickness direction of the charging device 100. For example, as Figure 3 The direction of arrow S1 in the diagram.

[0052] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the charging device 100 of this solution, by forming an installation cavity 11 inside the outer casing 10, the main board 20 and the electrical component 30 can be installed into the installation cavity 11, and the main board 20 is further electrically connected to the electrical component 30, so that the electrical component 30 can be connected to an external cable to realize the wiring operation of the charging device 100.

[0053] Furthermore, compared to the traditional charging device 100, this solution adds a protective plate 40 inside the mounting cavity 11 of the housing 10. The protective plate 40 is arranged along the first direction of the charging device 100, covering at least part of the main board 20 and electrical components 30. This allows the protective plate 40 to provide shielding protection for the main board 20 and electrical components 30. When the user performs installation work on the charging device 100, the protective plate 40, positioned above the main board 20 and electrical components 30, not only blocks tools used for installation work, preventing them from accidentally entering the installation area of ​​the main board 20 and electrical components 30 and damaging them, but also prevents accidentally falling parts, metal shavings, and other foreign objects from falling onto the main board 20 and electrical components 30, thus avoiding short circuits and other problems. This ensures that the charging device 100 can complete wiring and installation smoothly and safely, guaranteeing normal operation of the charging device 100 and eliminating potential safety hazards such as damage and short circuits.

[0054] It should be noted that regardless of whether the charging device 100 is laid flat on the ground in a horizontal position for installation, or is installed vertically on the ground or wall-mounted, the protective plate 40 is always placed above the main board 20 and the electrical components 30. In this case, the protective plate 40 can cover the main board 20 and the electrical components 30, thus providing protection for both.

[0055] Please continue reading. Figure 3 , Figure 4 , Figure 6 and Figure 7 Furthermore, based on the above embodiments, the charging device 100 also includes a mounting plate 50, which is installed inside the mounting cavity 11. For example, the mounting plate 50 can be installed and fixed to the shell wall of the outer casing 10 by at least one of the following methods: screwing, snap-fitting, or bonding. The choice can be made flexibly according to actual needs, and no specific limitation is made at this time.

[0056] The protective plate 40 is connected to the mounting plate 50 and / or the housing 10, and the protective plate 40 and the mounting plate 50 are arranged side by side and spaced apart along the first direction to form a receiving cavity 60. The main board 20 and the electrical components 30 are both mounted on the mounting plate 50, or the main board 20 is mounted on the mounting plate 50, the electrical components 30 are electrically mounted on the main board 20, and the main board 20 and at least part of the electrical components 30 are located inside the receiving cavity 60.

[0057] The protective plate 40 is connected to the mounting plate 50 and / or the housing 10, thereby supporting and positioning the protective plate 40 above the mounting plate 50 through the mounting plate 50 and / or the housing 10, and the protective plate 40 and the mounting plate 50 are spaced apart to form a receiving cavity 60. The receiving cavity 60 can be used to accommodate the motherboard 20 and the electrical components 30 mounted on the mounting plate 50, so that the protective plate 40 covers the motherboard 20 and the electrical components 30, thereby achieving the effect of shielding and protecting them.

[0058] Please continue reading. Figures 1 to 3 In one embodiment, the outer casing 10 includes a first casing 12 and a second casing 13, wherein the first casing 12 is detachably disposed on the second casing 13. When the first casing 12 and the second casing 13 are assembled, the first casing 12 and the second casing 13 form a mounting cavity 11, and the first casing 12 and the second casing 13 are sealed together to form a closed cavity in the mounting cavity 11.

[0059] The outer casing 10 is designed as a split structure of a first casing 12 and a second casing 13, and the first casing 12 and the second casing 13 are detachably connected. By removing the first casing 12 from the second casing 13, the electrical component 30 inside the mounting cavity 11 can be exposed, thereby facilitating the wiring operation of the electrical component 30 with external cables.

[0060] When the first housing 12 and the second housing 13 are assembled and fixed, the first housing 12 and the second housing 13 are sealed together, thereby forming the mounting cavity 11 into a closed cavity, improving the sealing and protection performance of the outer shell 10, and preventing dust, rainwater and other external environmental elements from entering the mounting cavity 11 and causing damage to the motherboard 20, electrical components 30 and the like.

[0061] It should be noted that the sealing connection between the first housing 12 and the second housing 13 can be achieved by sealing the assembly structure on the annular assembly surface of the first housing 12 and the second housing 13, or by installing sealing components (such as sealing rings) on the annular assembly surface of the first housing 12 and the second housing 13, etc.; the specific choice can be made flexibly according to actual needs.

[0062] Please continue reading. Figure 3 The mounting plate 50 is installed on the second housing 13, and the protective plate 40 is positioned closer to the first housing 12 than the mounting plate 50. When the first housing 12 is removed from the second housing 13, the protective plate 40 is closest to the user, and the protective plate 40 covers the mainboard 20 and electrical components 30 below it, thus providing a shielding and protective effect for the mainboard 20 and electrical components 30.

[0063] Furthermore, in one embodiment, the inner wall of the second housing 13 is provided with a first threaded post 133 protruding towards the first housing 12, and the first housing 12 is provided with a first threaded component. The first threaded component is screwed to the first threaded post 133 to assemble and fix the first housing 12 and the second housing 13. Therefore, during installation, the first threaded component is threadedly connected to the first threaded post 133, thereby locking and fixing the first housing 12 and the second housing 13. This threaded installation method has a simple structure, high connection reliability, and convenient and labor-saving assembly and disassembly operations.

[0064] Please continue reading. Figure 3 and Figure 4 More preferably, multiple first threaded posts 133 are provided, and the multiple first threaded posts 133 are arranged along the circumference of the second housing 13 on the inner wall of the second housing 13; correspondingly, multiple first threaded components are also provided on the first housing 12, and the first threaded components are installed one-to-one with the first threaded posts 133 to circumferentially lock and fix the first housing 12 and the second housing 13, thereby improving the stability of the installation and the sealing performance after assembly.

[0065] Of course, in other optional embodiments, the first housing 12 and the second housing 13 can also be detachably assembled by means of snap-fit ​​connection, magnetic connection, adhesive bonding, etc., and can be flexibly selected according to actual needs, which will not be elaborated here.

[0066] Please continue reading. Figures 3 to 7 Furthermore, in another embodiment, the mounting plate 50 is provided with a second threaded post 51 protruding towards the protective plate 40, and the protective plate 40 is provided with a second threaded component. The second threaded component is screwed to the second threaded post 51 to assemble and fix the protective plate 40 and the mounting plate 50. During installation, the second threaded component is threadedly connected to the second threaded post 51, thereby locking and fixing the protective plate 40 and the mounting plate 50. This threaded installation method has a simple structure, high connection reliability, and convenient and labor-saving installation and disassembly operations. Moreover, because the second threaded post 51 itself has a certain height, the second threaded post 51 can support the protective plate 40 to be arranged at a certain height above the mounting plate 50, which facilitates the formation of a receiving cavity 60 between the protective plate 40 and the mounting plate 50 to accommodate the main board 20 and the electrical components 30.

[0067] More preferably, multiple second threaded posts 51 are provided, and the multiple second threaded posts 51 are arranged around the periphery of the mounting plate 50; correspondingly, multiple second threaded components are also provided on the protective plate 40, and the second threaded components are installed one-to-one with the second threaded posts 51, so as to achieve more stable support and positioning of the protective plate 40 through the multiple second threaded posts 51, and at the same time improve the connection strength between the protective plate 40 and the mounting plate 50.

[0068] Of course, in other optional embodiments, the protective plate 40 and the mounting plate 50 can also be detached and assembled by means of snap-fit ​​connection, magnetic connection, adhesive, etc., which can be flexibly selected according to actual needs, and will not be elaborated here.

[0069] Please continue reading. Figures 4 to 6 Based on any of the above embodiments, the electrical component 30 includes a terminal block 31 disposed on the mounting plate 50. The terminal block 31 includes a first power contact portion 311, which is electrically connected to the main board 20. The first power contact portion 311 is located inside the receiving cavity 60 and is covered below the protective plate 40.

[0070] Please continue reading. Figures 4 to 6 In addition, based on the above embodiments, the terminal block 31 also includes a second power connection part 312. The second power connection part 312 extends out of the receiving cavity 60 and is exposed on the protective plate 40. The second housing 13 has a wire passage hole 131 for external cables to pass through, so that the external cables can extend into the mounting cavity 11 and connect with the second power connection part 312.

[0071] In actual installation, external cables can be passed through the cable guide hole 131, allowing them to extend into the mounting cavity 11 for electrical connection with the second power connector 312. This assembles the external cable with the terminal block 31, allowing current from the external cable to flow into the motherboard 20 via the terminal block 31. Specifically, the current flowing into the terminal block 31 can also flow into the motherboard 20 via the first power connector 311, resulting in a simple current transmission structure and method. For example, the first power connector 311 can be electrically connected to the motherboard 20 via a connecting wire.

[0072] As is easily understood, the first power connector 311 is positioned inside the receiving cavity 60 and covered by the protective plate 40. This allows the protective plate 40 to shield and protect the connection between the first power connector 311 and the main board 20, preventing accidental damage from tools or short circuits caused by falling foreign objects during installation. The second power connector 312 extends outside the receiving cavity 60 and is exposed on the protective plate 40. After removing the first housing 12, the second power connector 312 is directly within the user's field of vision, facilitating wiring operations and improving installation efficiency and user experience.

[0073] It should be noted that there are two cable passage holes 131 on the second housing 13. The external cables include an AC input cable and a charging gun cable. The AC input cable is installed through one of the cable passage holes 131, and the charging gun cable is installed through the other cable passage hole 131. Both the AC input cable and the charging gun cable are connected to the terminal block 31. During the use of the charging device 100, the AC input cable inputs current to the main board 20 through the terminal block 31. After being processed by the main board 20, the current flows back into the charging gun cable through the terminal block 31. The charging gun cable is used to connect to electrical equipment (such as new energy vehicles) to charge the electrical equipment.

[0074] Please continue reading. Figure 3 , Figure 4 and Figure 7 Furthermore, based on the above embodiments, the charging device 100 also includes a guide rail 70, which is disposed on the mounting plate 50, and the wiring terminal 31 is movably disposed on the guide rail 70. This movable mounting of the wiring terminal 31 on the guide rail 70 allows for convenient and flexible adjustment of its position on the mounting plate 50, thereby facilitating wiring operations.

[0075] Understandably, the terminal block 31 is provided with a sliding seat that is compatible with the guide rail 70. The sliding seat is installed on the guide rail 70 and can slide relative to it.

[0076] To prevent dust, rainwater, and other external environmental elements from entering the mounting cavity 11 through the cable passage hole 131 and damaging the motherboard 20, electrical components 30, etc., in one embodiment, the cable passage hole 131 is formed at one end of the second housing 13 along the second direction of the charging device 100, and a waterproof connector 80 is installed at the cable passage hole 131 for sealing and engaging with external cables.

[0077] The second direction specifically refers to the length direction of the charging device 100. For example, Figure 3 and Figure 4 The direction of arrow S2 in the diagram.

[0078] Please continue reading. Figure 5 Furthermore, based on any of the above embodiments, a first protective gap 90 is formed between the terminal block 31 and the protective plate 40. The first protective gap 90 can restrict tools and / or foreign objects from entering the receiving cavity 60. That is, by reasonably controlling the size of the first protective gap 90, tools and / or foreign objects (such as parts) can be prevented from entering the receiving cavity 60 from the side and causing damage to the main board 20 and electrical components 30 or causing short circuit problems.

[0079] Please continue reading. Figure 4 and Figure 5Furthermore, the electrical component 30 also includes a residual current device (RCD) 90a, which is mounted on the mounting plate 50 and electrically connected to the main board 20. The RCD 90a and the terminal block 31 are arranged side-by-side at intervals along a third direction of the charging device 100 on the mounting plate 50. The RCD 90a is provided to provide leakage protection for the charging device 100, preventing electric shock accidents in the event of accidental leakage.

[0080] The third direction can refer to the width direction of the charging device 100. For example, Figure 4 The direction of arrow S3 in the diagram.

[0081] Furthermore, a second protective gap 90b is formed between the residual current device 90a and the protective plate 40, which can restrict tools and / or foreign objects from entering the receiving cavity 60.

[0082] A third protective gap 90c is formed between the residual current device 90a and the terminal block 31, which can restrict tools and / or foreign objects from entering the receiving cavity 60.

[0083] Similarly, by properly controlling the size of the second protective gap 90b and the third protective gap 90c, tools and / or foreign objects (such as parts) can be prevented from entering the receiving cavity 60 from the side and causing damage to the mainboard 20 and electrical components 30 or causing short circuit problems.

[0084] Please continue reading. Figure 3 and Figure 4 In another embodiment, the electrical component 30 also includes an emergency stop button 90d. The second housing 13 has a mounting through-hole 132 on one side facing the third direction S3. The emergency stop button 90d is movably inserted into the mounting through-hole 132. The emergency stop button 90d is electrically connected to the main board 20, and the electrical connection between the emergency stop button 90d and the main board 20 is covered below the protective plate 40. By providing the emergency stop button 90d and electrically connecting it to the main board 20, the equipment can be shut down promptly in case of an abnormality during the operation of the charging device 100, preventing safety accidents. Covering the electrical connection between the emergency stop button 90d and the main board 20 below the protective plate 40 allows the protective plate 40 to shield tools and metal shavings, protecting the emergency stop button 90d for safety and normal use.

[0085] Understandably, the emergency stop button 90d is installed in the mounting through hole 132 through an elastic element. When the emergency stop button 90d is pressed, it can contact the main board 20 to conduct electricity, thereby achieving the purpose of emergency stop of the charging device 100. When the emergency stop button 90d is released, the elastic element drives the emergency stop button 90d to reset itself for the next operation, thereby improving the automation level of the charging device 100.
