Description
Technical Field
[0001] This utility model relates to louvered windows, and more particularly to a double-layered louvered window that is dustproof, waterproof, and noise-reducing. Background Technology
[0002] Venetian blinds are used for airflow cooling of charging modules in charging piles. Cool air is drawn into the module by its built-in fan, and then hot air is blown out through the blinds. Charging pile products typically need to consider waterproofing, dustproofing, and noise reduction. Specifically, while ensuring good ventilation through the blinds, they must also meet IP54 waterproof and dustproof requirements, and noise reduction for high-power fans that generate significant noise is also crucial. Currently, most venetian blinds only have a single layer of waterproofing and lack noise reduction capabilities. A single layer of venetian blinds is insufficient for achieving high-strength waterproofing, making the charging pile prone to leaks that could damage internal components and compromise its safety. Furthermore, when charging modules incorporate high-power fans, the traditional venetian blinds, due to their weak noise reduction capabilities, significantly contribute to noise pollution when supporting these high-power fans.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0027] This utility model discloses a double-layer louvered dustproof, waterproof and noise-reducing louvered window. It is designed with a double-layer louvered structure, which has strong waterproof performance. Based on the detachable fan mounting plate 4 and protective plate 5, dustproof cotton and sound-absorbing cotton are set in the structure, which facilitates the cleaning and maintenance of the louvered window. At the same time, the louvered window of this new type has good dustproof and noise reduction performance.
[0028] The overall structural design of this new type of louver is as follows: Figure 1-3As shown, the main structure includes: an external protective window shell 1, an integrated double-layer louver mechanism with strong waterproof performance 3, a fan mounting plate 4, and dustproof cotton 6 and sound-absorbing cotton 7 installed inside the fan mounting plate 4.
[0029] The integrated double-layer louver mechanism 3 is first assembled inside the waterproof layer frame 2, and then connected to the window shell 1 using the waterproof layer frame 2.
[0030] like Figure 3 and Figure 4 As shown, the integrated double-layer louver mechanism 3 contains several louver units arranged vertically. From the side, the louver units have an M-shaped structure design. For ease of description, the 100-page unit is divided into a first-level 100-page unit and a second-level 100-page unit, such as... Figure 5 As shown, the first layer of louvered units and the second layer of louvered units are integrally bent into shape; The front end of the first layer of louvers is inclined at an angle of 60 degrees relative to the horizontal plane, and the tail end of the two bends is horizontal, so that the tail end of the first layer of louvers can be vented flat. A first drainage notch 32 is opened at the bend end of the first layer of louvers to facilitate water discharge and air venting. The first drainage notch 32 is bent upward to form a first water-blocking strip 31 to prevent rainwater from splashing in.
[0031] The front end of the second louver unit is also inclined, with an angle of 70 degrees relative to the horizontal plane. The bent tail of the second louver unit is raised at 50 degrees relative to the horizontal plane, and a second water-blocking strip 34 is formed at the end of the bent tail, bending upward at 90 degrees relative to the bent tail, to prevent water from overflowing. Preferably, the height of the second water-blocking strip 34 is 9mm. At the same time, a second drainage notch 33 is left at the two bent tails of the second louver unit to facilitate the downward drainage of accumulated water.
[0032] Based on the above structural features, several louvered units are arranged at intervals along the height of the waterproof layer frame 2, forming a structure as follows: Figure 3 The integrated double-layer venetian blind mechanism 3 shown has a first layer of venetian blinds arranged vertically to form the first layer of venetian blinds at the front, and a second layer of venetian blinds arranged vertically to form the second layer of venetian blinds at the rear. The structural units of the double-layer venetian blinds are arranged vertically and alternately in the inner cavity of the waterproof layer frame 2 to achieve the strong waterproof performance of this new type of venetian blind.
[0033] For the integrated double-layer louver mechanism 3, its assembly and connection with the waterproof layer frame 2 is specifically achieved through pre-drilled holes and pop rivets. For example... Figure 5As shown, each louver unit of the first and second louvers has bent lugs on both sides, and mounting holes 35 are provided on the bent lugs. Correspondingly, fixing holes adapted to the mounting holes 35 are reserved on the side wall of the waterproof layer frame 2. Both the mounting holes and the fixing holes are rivet holes. After the pop rivets pass through the mounting holes 35 and the fixing holes for fixing, the integrated double-layer louver window mechanism 3 is fixed inside the waterproof layer frame 2.
[0034] The waterproof layer frame 2 connects the integrated double-layer louver mechanism 3 to the window shell 1 through flange nuts. The studs pass through the corresponding holes and are locked with the flange nuts to achieve fixed assembly. In addition, a layer of 1.5mm thick EPDM foam can be covered between the connection surfaces of the waterproof layer frame 2 and the window shell 1 to enhance the connection and sealing between the sheet metal parts.
[0035] The waterproof layer frame 2, on the other hand, provides a location for connecting the fan mounting plate 4 and the protective plate 5. The protective plate 5 is installed between the waterproof layer frame 2 and the fan mounting plate 4, and the fan mounting plate 4 and the protective plate 5 are assembled and connected to the waterproof layer frame 2 by rivet screws at the four corners. Both the fan mounting plate 4 and the protective plate 5 are installed in a detachable manner, which facilitates the subsequent cleaning and maintenance of the louvers, as well as the replacement of the internal dustproof cotton 6 and sound-absorbing cotton 7.
[0036] At the same time, water blocked by the louvers will also fall into the waterproof layer frame 2, therefore, as Figure 7 As shown, the waterproof layer frame 2 is designed as a frame structure with trapezoidal sides, bent at 90 degrees at the top and 80 degrees at the bottom, that is, the bottom of the waterproof layer frame 2 is an inclined slope, which facilitates the drainage of water blocked on the louvers.
[0037] like Figure 6 As shown, a drain opening 21 is provided on the bottom slope of the waterproof layer frame 2. The drain opening 21 is connected to the heat dissipation hole 11 at the bottom of the window shell 1, allowing water blocked on the louvers to drain out through the heat dissipation hole 11. Furthermore, the surface of the window shell 1 is provided with several ventilation holes (e.g., hexagonal holes). These ventilation holes occupy a large area of the surface of the window shell 1, typically matching the area of the integrated double-layer louver mechanism 3, and covering the drain end of the lower slope of the waterproof layer frame 2, facilitating water flow out from the slope. Thus, the drain opening, heat dissipation hole, and ventilation hole provide a multiple drainage mechanism to ensure effective drainage of water blocked on the louvers.
[0038] Dustproof cotton 6 and sound-absorbing cotton 7 are installed inside the fan mounting plate 4. The sound-absorbing cotton 7 is made of wavy sound-absorbing cotton, which achieves a certain degree of dust prevention and also has a sound absorption and noise reduction effect. The sound-absorbing cotton 7 is fixed inside the fan mounting plate 4 by adhesive on its back, so that the sound-absorbing cotton 7 is in close contact with the fan mounting surface to achieve a good sound absorption and noise reduction effect. The dustproof cotton 6 is made of 40PPI dustproof black cotton, which can filter dust to achieve dust prevention. The dustproof cotton 6 is directly inserted into the fan mounting plate 4, and its position is fixed by the protective plate 5.
[0039] The structure of protective plate 5 is as follows Figure 8 As shown, the panel has multiple ventilation openings 51 to ensure the ventilation of the louvers.
[0040] The structure of the fan mounting plate 4 is as follows Figure 9 As shown, holes 41 are pre-drilled on the fan mounting plate 4 for installing the fan 8. The fan 8 is installed at the holes 41 using rivet screws and nuts. The finished installation state is as follows. Figure 10 As shown.
[0041] Therefore, for the double-layer louvered dustproof, waterproof and noise-reducing louvered window disclosed in this utility model, the integrated double-layer louvered window mechanism 3 is first fixed in the waterproof layer frame 2 through the pre-reserved mounting holes and fixing holes on both sides and the core-pulling rivets, and then the waterproof layer frame 2 is connected to the window shell 1 by the flange nuts.
[0042] Inside the fan mounting plate 4, the sound-absorbing cotton 7 is fixed to the fan mounting plate 4 by its adhesive backing, and the dustproof cotton 6 is directly inserted into the fan mounting plate 4. The dustproof cotton 6 is blocked by the protective plate 5 to fix its position. Then, the fan mounting plate 4 and the protective plate 5 are detachably assembled and connected to the waterproof layer frame 2 by the rivet screws at the four corners.
[0043] The working principle of this new type of louvered window for dustproofing, waterproofing and noise reduction is as follows: When ordinary rainwater impacts, a small portion of the rainwater will be blocked by the hexagonal vent holes of the window shell 1. The remaining rainwater will be blocked by the first sloping louver (i.e., the first layer of louver). The blocked rainwater will flow down the slope and fall to the bottom slope of the waterproof layer frame 2. The rainwater seeping down from the drain opening 21 will be discharged through the heat dissipation holes 11 of the window shell 1. The rainwater flowing down the slope will flow out from the hexagonal vent holes of the window shell 1.
[0044] When a strong rainwater flow impacts the first layer of louvers, the rainwater is first impacted by the strong wind. The 60-degree slope of the first layer of louvers blocks most of the rainwater and it flows down the slope. The second layer of louvers is staggered with the next level of the first layer of louvers to fill the gaps between the louvers and block the vast majority of the rainwater. The blocked rainwater flows out through the drainage opening 21 and the hexagonal vent hole along the bottom slope of the waterproof layer frame. If there is splashing or upward water flow, some of it will be blocked by the first water-blocking strip 31 at the end of the first layer of louvers or flow out from the first drainage hole 31. The remaining water will fall downward into the second layer of louvers due to gravity. The two bends of the second layer of louvers will cause the rainwater to flow towards the second drainage hole 33. At the same time, the raised end of the second layer of louvers and the second water-blocking strip 34 at a 90-degree angle prevent water from overflowing. Finally, the rainwater flows down layer by layer and flows out through the drainage opening 21 and the hexagonal vent hole along the bottom slope of the waterproof layer frame. During the process of strong waterproofing and rain protection, wind and sand will also be blocked by the double-layer louvers. Fine dust that escapes into the equipment will be blocked by the holes of the dustproof cotton 6, while the noise generated by the fan 8 will be absorbed by the sound-absorbing cotton 7, reducing noise pollution.
[0045] In addition, it should be noted that both the dustproof cotton 6 and the sound-absorbing cotton 7 have a porous structure, allowing the airflow of the fan to pass through without affecting the ventilation of the entire louver.
[0046] Compared with existing technologies, this new type of double-layer louvered dustproof, waterproof, and noise-reducing louver has the following technical advantages: 1) The louvered window, with its integrated double-layer M-shaped louver, can block the impact of rainwater under strong winds. While ensuring a certain level of ventilation and heat dissipation, it can prevent natural rainwater from washing away and dust from entering the equipment, reducing the probability of damage to electrical equipment and improving the protective capability of the louvered window. It is suitable for use in power equipment that requires ventilation and heat dissipation, such as charging piles and rectifier cabinets.
[0047] 2) The sound-absorbing cotton attached to the back of the fan absorbs the noise of the fan, allowing product designers to choose high-power, high-volume fans while meeting noise requirements, thus reducing noise pollution generated by the fan.
[0048] 3) The fan mounting plate of this louver is detachable, and the dustproof cotton and sound-absorbing cotton inside the dustproof and noise-reducing frame can be replaced, which facilitates the cleaning and maintenance of the louver in the future.
[0049] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
