Description

Technical Field

[0001] This application relates to the field of charger technology, specifically to a charger noise reduction and protection device. Background Technology

[0002] To meet the ever-increasing demand for vehicle charging, more and more charging infrastructure is being deployed in outdoor or semi-outdoor environments. As the core equipment for replenishing the energy supply of electric vehicles, the charger works by rectifying and regulating the externally input three-phase AC power through its internal charging module, converting it into DC power adapted to the battery characteristics, and then supplying power to the electric vehicle's battery. During this process, the power devices inside the charging module generate a large amount of heat. If this heat is not dissipated in time, it will seriously affect the efficiency and reliability of the charging module. To ensure the stable operation of the charging module, a wind-cooling solution is usually adopted, which uses the high-speed operation of the built-in fan and the cooling fan in the cabinet to quickly dissipate heat. However, while this cooling method achieves efficient cooling, it generates significant noise, causing noticeable noise pollution to the surrounding environment. Utility Model Content

[0032] Figure 1 and Figure 2 This application provides structural schematic diagrams of a charger noise reduction and protection device 100 from different perspectives, as shown in the embodiments below. Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a charger noise reduction and protection device 100, including a housing 10 and a base 20. The housing 10 is used to house the charger 1 and provide protection and noise reduction for the charger 1. The base 20 is disposed at the bottom of the housing 10, serving as the mounting base for the housing 10, and is used to provide support and waterproof protection for the charger 1. The various parts are described in detail below.

[0033] Box 10 has a rectangular parallelepiped structure. For example... Figure 3 and Figure 4As shown, the bottom surface of the enclosure 10 is open and mounted on the base 20. A sealant is applied between the bottom surface of the enclosure 10 and the base 20, serving a waterproof sealing function. This sealant can be neoprene, silicone rubber, fluororubber, or other materials. The top surface and four sides of the enclosure 10 have a multi-layer composite structure, comprising at least one metal plate and at least one sound-absorbing material layer 11. As an example, the multi-layer composite structure is a three-layer structure, with the outer and inner layers being metal plates and the middle layer being the sound-absorbing material layer 11. As another example, the multi-layer composite structure is a two-layer structure, with the outer layer being a metal plate and the inner layer being a sound-absorbing material layer. The metal plate can be cold-rolled steel, galvanized steel, aluminum alloy, stainless steel, or other materials, and the sound-absorbing material layer 11 can be glass wool, polyester fiber, aluminum foam, or other sound-absorbing materials.

[0034] The side of the enclosure 10 is equipped with an inspection window 12, an inspection door 13, and an operating door 14. The inspection window 12 is positioned directly opposite the air outlet of the charger 1 to facilitate heat dissipation. The inspection door 13 allows personnel to enter and exit the enclosure 10 for routine maintenance of the charger 1. The operating door 14 is positioned directly opposite the side where the control buttons of the charger 1 are located, facilitating operation. The inspection window 12 adopts a sound-absorbing louver structure, providing both ventilation and noise reduction functions. The sound-absorbing louver structure includes multiple parallel blades, each of which can be made of metal or engineering plastic. The surface of the blades has micropores or grooves to enhance sound energy dissipation. The inner side or cavity of the blades can be filled with sound-absorbing material. The blades are arranged at an angle relative to the horizontal plane, typically 30°-45°, allowing sound wave energy to be dispersed and attenuated through multiple reflections and refractions between the blades.

[0035] As an example, such as Figures 1 to 3 As shown, the front side of the enclosure 10 has two inspection windows 12 and one operating door 14, the rear side of the enclosure 10 has one inspection window 12 and one inspection door 13, the left side of the enclosure 10 has one operating door 14, and the right side of the enclosure 10 has one inspection window 12. At least a portion of the inspection door 13 can also adopt a sound-absorbing louver structure (the entire inspection door 13 in the figure adopts a sound-absorbing louver structure) to ensure air circulation (mainly air intake) and reduce noise transmitted to the outside of the enclosure 10. The inspection window 12 on the rear side of the enclosure 10 has a double-sash structure, while the other inspection windows 12 have a single-sash structure, and each sash can be opened and closed independently.

[0036] The enclosure 10 has multiple charger installation areas and a maintenance passage 15 inside. The multiple charger installation areas can be arranged separately, and each charger installation area can be equipped with one charger 1. The maintenance passage 15 is arranged next to the multiple charger installation areas and connects to the maintenance door 13 for personnel passage.

[0037] As an example, such as Figure 5 and Figure 6 As shown, the enclosure 10 has three charger installation areas inside, spaced apart along the length of the enclosure 10 and adjacent to its front side. Each area houses one charger 1, for a total of three chargers 1. The space between the three chargers 1 and the space from the three chargers 1 to the rear side of the enclosure 10 constitutes a maintenance passage 15. Two chargers 1 have air inlets facing the right side of the enclosure 10 and connected to the maintenance passage 15, while their air outlets face the two maintenance windows 12 on the front side of the enclosure 10. The air inlet of the third charger 1 faces the maintenance window 12 on the rear side of the enclosure 10, and its air outlet faces the maintenance window 12 on the right side of the enclosure 10. It should be noted that the air inlets and outlets of the chargers 1 are located on two different sides of each charger 1 and are each composed of multiple ventilation holes.

[0038] To prevent warm air from the charger 1 outlet from flowing back into the housing 10 and affecting the charger 1's heat dissipation, such as... Figure 4 As shown, a sealing element 16 is provided around the air outlet of each charger 1 and between the corresponding inspection window 12. The sealing element 16 can be made of foam, rubber or other sealing materials, and the sealing element 16 can be arranged by bonding, pressing or other methods.

[0039] The top of the enclosure 10 is equipped with a camera 17, a light 18, and a smoke detector 19. The camera 17 is used for monitoring the interior of the enclosure 10, the light 18 is used for lighting the interior of the enclosure 10, and the smoke detector 19 is used to monitor smoke particles in the air inside the enclosure 10, so as to detect fire hazards in a timely manner and issue an alarm.

[0040] As an example, such as Figure 5 As shown, a camera 17 is provided at one end of the top of the maintenance passage 15 of the enclosure 10, and multiple lights 18 are distributed on the top of the maintenance passage 15 of the enclosure 10. A smoke detector 19 is provided at the center of the top of the enclosure 10.

[0041] like Figure 6 and Figure 7 As shown, the base 20 has a multi-level platform structure. The top platform is used to place the charger 1, and the other platforms are used to connect to the bottom of the housing 10. The multi-level platform structure serves as a physical waterproofing mechanism.

[0042] As an example, the base 20 is a two-tiered platform structure made of concrete, comprising a lower first platform 21 and an upper second platform 22. The housing 10 is mounted on the first platform 21, and the bottom surface of the housing 10 is sealed to the first platform 21 with sealant. The charger 1 is mounted on the second platform 22, ensuring that even if the sealant on the first platform 21 fails, water will not enter the charger 1 through the second platform 22.

[0043] The base 20 is provided with multiple cable passage holes for the charging cable to enter and / or exit, which can meet various cable entry and exit configurations of the charger 1, including bottom entry and top exit, bottom entry and bottom exit, top entry and bottom exit, and top entry and top exit. Each cable passage hole extends vertically through the base 20, thereby guiding the cable below the ground and avoiding the need for openings in the housing 10, which would affect the sealing, heat dissipation, and aesthetics of the housing 10.

[0044] As an example, such as Figure 6 and Figure 7 As shown, the cable passage includes three first cable passages 23 for the charging machine 1 to enter the cable and three second cable passages 24 for the charging machine 1 to exit the cable. The three charging machines 1 are arranged with bottom cable entry and top cable exit. Each charging machine 1 is equipped with a cable tray 2. The upper end of each cable tray 2 is connected to the top surface of the charging machine 1, the main body of the cable tray 2 is connected to the side of the charging machine 1, and the lower end of the cable tray 2 is connected to a second cable passage 24.

[0045] In summary, the charger noise reduction and protection device provided in this application embodiment features a multi-layered composite structure housing with a sound-absorbing material layer, providing protection and noise reduction for the charger. The inspection window of the housing is designed as a sound-absorbing louver structure, combining ventilation and noise reduction functions. The charger is placed on a base, which raises the mounting surface of the charger, providing support and waterproof protection. The base also has cable routing holes for convenient cable arrangement. The overall structure is simple, combining stability and low cost, significantly reducing noise pollution while effectively ensuring the safe operation of the charger.

[0046] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application.
