Description

Technical Field

[0001] This utility model relates to the field of automotive noise reduction technology, and in particular to a noise reduction and heat dissipation structure for a charging device. Background Technology

[0002] Currently, most car charging equipment adopts a straight-in-straight-out louvered air duct design for heat dissipation. While this duct structure has relatively low air resistance, the characteristics of the louvers allow noise to be directly transmitted to the outside of the equipment through the gaps between the louvers, resulting in relatively high equipment noise. In some charging stations, a soundproof enclosure is added around the charging equipment. While this effectively reduces noise, it requires additional space for installation. In some locations, due to special circumstances (such as streetlights, flower beds, and sewer steps), soundproof enclosures cannot be installed, and their cost is also high. Other charging stations simply add a soundproof cover to the outside of the charging equipment's ventilation openings, with a large amount of sound-absorbing cotton lined inside. To achieve a certain level of noise reduction, this soundproof cover needs to be about 30 centimeters thick, which significantly impacts the equipment's appearance. Furthermore, in some stations, it may prevent the doors from opening fully, affecting after-sales maintenance.

[0003] The main purpose of this invention is to solve problems such as noise reduction in existing charging equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a noise reduction and heat dissipation structure for a charging device, which does not require an external noise reduction device, saves space, and is aesthetically pleasing and has excellent noise reduction effect.

[0005] To achieve the above objectives, the noise reduction and heat dissipation structure of the charging device provided by this utility model includes a segmented waterproof maze assembly, a door panel assembly, a sound-absorbing cotton assembly, and a dustproof assembly that are stacked sequentially. The segmented waterproof maze assembly is used for waterproofing and blocking external insects. The sound-absorbing cotton assembly includes a first outer frame, a mounting frame, and sound-absorbing cotton. The first outer frame is a rectangular frame structure. The door panel assembly and the dustproof assembly are connected to both sides of the first outer frame. The mounting frames are arranged at intervals along the length direction of the first outer frame and along the width direction of the first outer frame. The mounting frames are inclined relative to the first outer frame. The sound-absorbing cotton is built into the mounting frame. The dustproof assembly is used for dust prevention.

[0006] Preferably, the segmented waterproof maze assembly includes a second outer frame, a segmented waterproof maze, and a stainless steel insect-proof net. The second outer frame is a rectangular frame structure. The segmented waterproof maze includes multiple waterproof sheets, which are arranged at an angle relative to the second outer frame. All the waterproof sheets are arranged at intervals along the length direction of the second outer frame and along the width direction of the second outer frame. The gaps between two waterproof sheets and the gaps between the second outer frame and the waterproof sheets are sealed by the stainless steel insect-proof net to prevent insects.

[0007] Specifically, the stainless steel insect-proof net is a 10-mesh stainless steel insect-proof net.

[0008] Specifically, the waterproof sheet is tilted at a 45-degree angle relative to the height direction of the second outer frame.

[0009] Preferably, the sound-absorbing cotton assembly further includes an elastic limiting piece, the mounting frame has a slot for receiving the sound-absorbing cotton, the slot has an opening, the elastic limiting piece is located at the edge of the opening of the mounting frame and is pivotally connected to the edge of the opening of the mounting frame, the elastic limiting piece has a blocking position that blocks the opening and an open position that releases the blocking, and the elastic limiting piece always has a tendency to rotate from the open position to the blocking position.

[0010] Specifically, the sound-absorbing cotton assembly further includes an elastic element that provides an elastic force that causes the elastic limiting piece to always have a tendency to rotate from the open position to the blocking position.

[0011] Specifically, the elastic limiting pieces are evenly arranged along the opening edge of the mounting frame.

[0012] Preferably, the dustproof component includes a metal frame and dustproof cotton. The metal frame is a cuboid frame structure with multiple arranged mounting holes inside. The dustproof cotton is attached to the metal frame by a sealing strip.

[0013] Specifically, the bottom of the metal frame forms a water collection trough through baffles.

[0014] Preferably, the sound-absorbing cotton is polyurethane foam.

[0015] Compared with existing technologies, the innovative feature of this utility model's noise reduction and heat dissipation structure for charging equipment lies in combining segmented waterproof labyrinth components, door panel components, sound-absorbing cotton components, and dustproof components. This integrates multiple functions such as waterproofing, sound absorption, and dustproofing. Simply install the door panel at the target ventilation location of the charging equipment. This reduces the noise level of the charging equipment while meeting the noise requirements of the surrounding area. It also lowers the operating costs of the charging station, as no external noise reduction equipment is required, thus improving the land and space utilization of the station. It does not increase the space occupied by the equipment, saving space while maintaining an aesthetically pleasing appearance and excellent noise reduction effect. Attached Figure Description

[0022] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] Please see Figures 1 to 6A noise reduction and heat dissipation structure 100 for a charging device is mainly used for installation at the air inlet of the charging device. It includes a segmented waterproof labyrinth assembly 1, a door panel assembly 2, a sound-absorbing cotton assembly 3, and a dustproof assembly 4. These components are stacked sequentially. The segmented waterproof labyrinth assembly 1 is used for waterproofing and blocking external insects. The sound-absorbing cotton assembly 3 includes a first outer frame 31, a mounting frame 32, and sound-absorbing cotton 33. The first outer frame 31 is a rectangular frame structure. The door panel assembly 2 and... The dustproof component 4 is connected to both sides of the first outer frame 31. The connection can be achieved by screws or adhesive. The mounting frames 32 are arranged at intervals along the length and width of the first outer frame 31, forming a horizontal, elongated shape. The mounting frames 32 are inclined relative to the first outer frame 31. Sound-absorbing cotton 33 is embedded within the mounting frames 32. The dustproof component 4 prevents dust by blocking it. This design combines waterproofing, sound absorption, and dustproofing functions. It only needs to be installed at the target ventilation location of the charging device via a door panel. Passing noise is absorbed by the sound-absorbing cotton component 3, achieving noise reduction. Since both the waterproof labyrinth component and the dustproof component 4 have through holes in their frame structures, these holes allow for heat dissipation from the charging device. Therefore, installing this noise-reducing and heat-dissipating structure on the charging device will not prevent heat from dissipating. In summary, this utility model meets the noise requirements of the charging equipment in the vicinity of the charging station while reducing the noise of the charging equipment, thereby reducing the operating costs of the charging station. This device does not require any external noise reduction equipment, thus improving the land and space utilization of the charging station and does not increase the space occupied by the equipment. It not only saves space but also has excellent aesthetics and noise reduction effects. More specifically, as follows: Please see Figures 5 to 6The segmented waterproof maze component 1 includes a second outer frame 11, a segmented waterproof maze 12, and a stainless steel insect-proof mesh 13. The second outer frame 11 is a rectangular frame structure and is connected to one side frame of the door panel component 2. The connection can be fixed by adhesive or threaded connection, and is therefore not limited to these methods. The segmented waterproof maze 12 includes multiple waterproof sheets 121, which are rectangular baffle structures. The waterproof sheets 121 are inclined relative to the second outer frame 11, with the length direction of the waterproof sheets 121 inclined at an angle of 30 to 45 degrees. The manufacturer can adjust this according to actual needs. In this embodiment, the waterproof sheets 121 are inclined at 45 degrees relative to the height direction of the second outer frame 11. All waterproof sheets 121 are arranged at intervals along the length of the second outer frame 11 and along the width of the second outer frame 11. The gaps between two waterproof sheets 121 and between the second outer frame 11 and the waterproof sheet 121 are sealed by stainless steel insect nets 13 to prevent insects. That is, the waterproof sheets 121 and the insect nets work together to keep mosquitoes out, ensuring heat dissipation while preventing mosquitoes from entering and affecting the charging equipment. In other words, it prevents foreign objects and small animals such as insects from entering the air duct, thus avoiding affecting the heat dissipation effect. Since the stainless steel insect net 13 has multiple small through holes, in this embodiment the stainless steel insect net 13 is a 10-mesh stainless steel insect net 13, but it is not limited to this. Therefore, it has a maze-like shape. This structure has the following advantages: First, the maze-type air duct structure is cheaper than the louver structure. Second, this structure can improve the waterproof rating of the charging equipment. The waterproof rating of the conventional louver structure is IPX4, and the special louver structure can achieve IPX5, but the wind resistance is large, which cannot meet the heat dissipation requirements of the charging equipment. This segmented labyrinth structure achieves an IPX5 waterproof rating while meeting the equipment's heat dissipation requirements, and its structural cost is lower than that of conventional louvered structures.

[0024] Please see Figure 4The sound-absorbing cotton assembly 3 also includes an elastic limiting piece 34. The mounting frame 32 has a slot 321 for receiving the sound-absorbing cotton 33. The slot 321 has an opening 322 facing downwards. The elastic limiting piece 34 is located at the edge of the opening 322 of the mounting frame 32 and is pivotally connected to the edge of the opening 322. The elastic limiting piece 34 has a blocking position that blocks the opening 322 and an open position that releases the blockage. The elastic limiting piece 34 always has a tendency to rotate from the open position to the blocking position. Specifically, the sound-absorbing cotton assembly 3 also includes an elastic element 35, which is disposed between the slot 321 and the elastic limiting piece 34. The elastic element 35 provides an elastic force that causes the elastic limiting piece 34 to always have a tendency to rotate from the open position to the blocking position. The sound-absorbing cotton 33 is installed using a combination of a slot 321 and an elastic limiting piece 34. During assembly, the elasticity of the metal directly and firmly secures the sound-absorbing cotton 33 within the slot 321, eliminating the need for any tools and greatly improving production efficiency. Furthermore, this sound-absorbing cotton 33 requires no additional maintenance during normal use, saving on after-sales costs. Preferably, the elastic limiting piece 34 is evenly distributed along the edge of the opening 322 of the mounting frame 32, but this is not a limitation. In addition, the sound-absorbing cotton 33 is made of polyurethane foam, has a relatively flat surface, is resistant to both low and high temperatures, has a service life of over 8 years, does not absorb water or dust, does not mold, has high flame retardant properties, and its fire resistance rating reaches UL94-V0. The material also meets environmental protection requirements. Under the same conditions, its sound insulation effect is more than 5dB higher than that of uneven sound-absorbing cotton 33 (commonly known as egg cotton). This sound-absorbing cotton 33 requires no maintenance during the lifespan of the charging station.

[0025] Please see Figures 1 to 2 The dustproof component 4 includes a metal frame 41 and a dustproof cotton 42. The metal frame 41 is a cuboid frame structure and is connected to the first outer frame 31. The metal frame 41 has a plurality of rectangular mounting holes 411 arranged inside. The dustproof cotton 42 is attached to the metal frame 41 by a sealing strip. A water collection groove is formed at the bottom of the metal frame 41 by a baffle 412, which opens outward from the bottom edge of the metal frame 41.

[0026] Please refer to the following: Figures 1 to 6 The working process of the noise reduction and heat dissipation structure 100 of the charging device of this utility model is as follows: The mounting frame 32 is installed at the ventilation position of the car charging equipment. Since it passes through the segmented waterproof labyrinth component 1, door panel component 2, sound-absorbing cotton component 3, and dustproof component 4, it only needs to be installed at the target ventilation position of the charging equipment through the door panel. The noise passing through is absorbed by the sound-absorbing cotton component 3 to achieve the purpose of noise reduction. Since the frame structure of the segmented waterproof labyrinth component 1 and the dustproof component 4 both have through holes, these through holes can dissipate heat for the charging equipment. Therefore, installing the noise reduction and heat dissipation structure of this utility model on the charging equipment will not prevent the heat of the equipment from being unable to dissipate. The dustproof and waterproof structure can prevent the setting of through holes from causing external debris to affect the internal structure of the charging equipment.

[0027] The innovative feature of this invention's noise reduction and heat dissipation structure 100 for charging equipment lies in its integration of a segmented waterproof labyrinth component 1, a door panel component 2, a sound-absorbing cotton component 3, and a dustproof component 4. This structure combines multiple functions, including waterproofing, sound absorption, and dustproofing. Simply install the door panel at the target ventilation location of the charging equipment. This reduces the noise level of the charging equipment while meeting the noise requirements of the surrounding area. It also lowers the operating costs of the charging station, as no additional external noise reduction equipment is needed, thus improving the land and space utilization of the station. It does not increase the space occupied by the equipment, saving space while maintaining an aesthetically pleasing appearance and excellent noise reduction effect. The noise reduction and heat dissipation structure 100 of this invention integrates multiple structures, including the segmented waterproof labyrinth component 1, the door panel component 2, the sound-absorbing cotton component 3, and the dustproof component 4, achieving an overall IP55 dustproof and waterproof rating.

[0028] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
