[0001] This utility model relates to the field of DC charging technology, and in particular to a DC charger. Background Technology

[0002] DC chargers are high-efficiency devices used for fast charging of electric vehicles. By providing high-power DC power, they significantly shorten charging time. With the continuous updates and development of the electric vehicle market, chargers have become increasingly popular, and their market value continues to grow, making them a core component of new energy infrastructure.

[0003] Existing DC chargers have insufficient protection levels, often resulting in problems such as water leakage, failure to meet protection requirements, or high manufacturing difficulty. Especially when used outdoors for extended periods, dust accumulation inside the charger is common, severely affecting the normal operation of internal components. This increases maintenance costs and significantly shortens the charger's lifespan, leading to reduced economic benefits and hindering market promotion.

[0004] Therefore, a DC charger is proposed to address the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a DC charger that can effectively improve waterproof performance, is easy to process, increases the service life of the charger, and reduces maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A DC charger includes a cabinet with two door panels rotatably connected to both sides. Taking one door panel as an example, a ventilation mesh is fixedly connected to the middle of the door panel, and a protective mechanism is installed in the middle of the door panel. The protective mechanism is directly opposite the ventilation mesh, and its central axis coincides with the central axis of the ventilation mesh. The protective mechanism includes multiple layers of louvers, which are horizontally aligned and tightly attached to each other.

[0008] The DC charger provided by this utility model, as described above, has the following beneficial effects:

[0009] This utility model features a ventilation mesh fixedly connected to the center of the door panel, with a protective mechanism installed in the center of the door panel. The protective mechanism is positioned directly opposite the ventilation mesh, with its central axis coinciding with the central axis of the ventilation mesh. The protective mechanism uses multiple layers of louvers, arranged horizontally and closely aligned, forming multiple continuous and reverse bending channels between the layers of louvers to achieve a physical barrier layer. Therefore, water sprayed from any angle cannot penetrate, effectively improving the waterproof performance of the DC charger. Furthermore, it is easy to process, extends the charger's service life, and reduces maintenance costs. Attached Figure Description

[0026] like Figures 1 to 9As shown, this utility model provides a technical solution: a DC charger, including a cabinet 100, with two door panels 200 rotatably connected to both sides of the cabinet 100. Taking one door panel 200 as an example, a ventilation mesh 210 is fixedly connected to the middle of the door panel 200, and a protective mechanism 230 is installed in the middle of the door panel 200. The protective mechanism 230 and the ventilation mesh 210 are arranged facing each other, and their central axis coincides with the central axis of the ventilation mesh 210. The protective mechanism 230 includes multiple layers of louvered strips 233, which are horizontally aligned and tightly attached to each other. By using multiple layers of louvered strips 233, with multiple layers inside and out, horizontally aligned and tightly attached to each other, multiple continuous and reverse bending channels are formed between the multiple layers of louvered strips 233, realizing a physical barrier layer. Therefore, water sprayed from any angle cannot penetrate, effectively improving the waterproof performance of the DC charger, and making it easy to process, increasing the service life of the charger, and reducing maintenance costs.

[0027] like Figure 6 As shown, each of the multi-layer louvered strips 233 is composed of several blades, and the blades are inclined bidirectionally curved. The blades in the multi-layer louvered strips 233 are relatively flat at the head and tail. The bidirectionally curved blades between the multi-layer louvered strips 233 form multiple continuous curves in the middle of the door panel 200, which can effectively block water vapor and dust without affecting the ventilation effect of the door panel 200.

[0028] like Figure 4 and Figure 5 As shown, a positioning bracket 231 is fixedly installed inside the door panel 200. The positioning bracket 231 is fixedly installed to the louver strip 233 by rivets. A frame assembly 232 is installed on one side of the positioning bracket 231. The frame assembly 232 consists of four metal beams, which are fixedly connected by rivets. The positioning bracket 231 is fixedly installed inside the frame assembly 232 by rivets. A pressure strip 260 is fixedly connected to the side of the frame assembly 232 away from the ventilation net 210. A stainless steel mesh 250 is installed on the opposite side of the pressure strip 260 and the frame assembly 232. A dustproof component 240 is installed on the side of the frame assembly 232 away from the ventilation net 210. The stainless steel mesh 250 can greatly improve the overall structural strength of the door panel 200.

[0029] like Figure 4 As shown, the dustproof component 240 includes a mounting frame 241 fixedly connected inside the door panel 200, and the interior of the mounting frame 241 is filled with dustproof cotton 242; the dustproof cotton 242 can further improve the DC charger's anti-interference effect against dust and moisture, thereby extending the service life of the DC charger.

[0030] like Figure 3 and Figure 4As shown, several ribs are fixedly connected to the middle of the mounting frame 241, and several screens are fixedly connected to the middle of the ribs; the screens can improve the stability of the dustproof cotton 242 and prevent the cotton from running out of the wires, and the ribs can support the screens, thereby improving the stability of the overall structure.

[0031] like Figure 8 As shown, the cabinet 100 has an inlet compartment and an outlet compartment. The outlet compartment houses a power module 110 and a DC output matrix module 120. The power module 110 is located directly above the DC output matrix module 120. A copper busbar 151 for cable connection is installed slightly below the outlet compartment. A cable outlet 130 is located at the bottom of the outlet compartment. The inlet compartment houses a main incoming circuit breaker 140 and an incoming copper busbar 150. The incoming copper busbar 150 is located below the main incoming circuit breaker 140. A cable inlet 131 is located at the bottom of the inlet compartment. Cables pass through the inlet compartment and the outlet compartment, and finally through the outlet 130, connecting the corresponding components inside the inlet and outlet compartments. This ensures that the wiring is orderly from left to right, and from top to bottom from the power module 110 to the DC output matrix module 120, which is natural and smooth, without cable crossing, avoiding interference, and is safe, aesthetically pleasing, and convenient for assembly and maintenance.

[0032] It should be noted that the power module 110, main incoming circuit breaker 140, DC output matrix module 120, incoming copper busbar 150, cable inlet 131, cable outlet 130 and outgoing copper busbar 151 are all existing technologies. Those skilled in the art can easily understand and implement the relevant solutions based on their names, so we will not elaborate further.

[0033] like Figure 7 As shown, the DC output matrix module 120 is externally mounted with an output protection plate 160, which is made of transparent material. The output protection plate 160 can effectively prevent the contact copper busbar 151 of the output wires when maintaining and repairing the DC charger, thereby eliminating safety hazards. At the same time, the transparent material makes it easy to visually inspect the condition of the device.

[0034] like Figure 7 As shown, a circuit breaker protective plate 161 is installed on the outside of the main incoming circuit breaker 140. A through hole is provided in the middle of the circuit breaker protective plate 161. The handle on one side of the main incoming circuit breaker 140 passes through the through hole to the outside of the circuit breaker protective plate 161. The circuit breaker protective plate 161 can prevent touching the incoming line connecting copper busbar 150, eliminating safety hazards. At the same time, the through hole of the circuit breaker protective plate 161 allows the handle of the main incoming circuit breaker 140 to pass through, making it convenient for manual operation of the main incoming circuit breaker 140 for opening and closing.

[0035] The working principle of this utility model is as follows: In use, after the power module 110, main incoming circuit breaker 140, circuit breaker protection plate 161, output protection plate 160, DC output matrix module 120, incoming copper busbar 150, cable inlet 131, cable outlet 130, and outgoing copper busbar 151 are installed in their respective positions, the cable flows from the cable inlet 131 through the inlet and outlet compartments, and finally through the cable outlet 130, connecting the corresponding components inside the inlet and outlet compartments. This ensures that the wiring is orderly from left to right, and from top to bottom from the power module 110 to the DC output matrix module 120. The design is natural and smooth, with no cable crossings, avoiding interference, ensuring safety and aesthetics, and facilitating assembly and maintenance. During ventilation, when affected by external moisture and dust, the multi-layered louvered strips 233 form multiple continuous bends in the middle of the door panel 200 through bidirectional curved blades. This effectively blocks moisture and dust without affecting the ventilation effect of the door panel 200. At the same time, the stainless steel mesh 250 greatly improves the overall structural strength of the door panel 200, and the dustproof cotton 242 further enhances the DC charger's resistance to dust and moisture interference, thereby extending the service life of the DC charger.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
