A charging pile muffling cover

Abstract

The application discloses a charging pile soundproof cover and belongs to the technical field of charging piles. The soundproof cover comprises an outer cover. The outer cover is the main structure of the soundproof cover and is detachably fixed on the air inlet and outlet of the charging equipment through a mounting piece. The outer cover defines a cavity for accommodating and guiding the propagation of sound. The cavity has a first opening through which sound propagates into the cavity of the outer cover. The inner wall of the outer cover is covered with a sound-absorbing layer for absorbing sound entering the cavity. The sound propagating into the cavity of the outer cover through the first opening is absorbed by the sound-absorbing layer covering the inner wall of the outer cover, thereby effectively reducing the propagation of sound of the charging equipment. Further, the cavity also has a second opening adjacent to the first opening, through which the heat of the air inlet and outlet of the charging equipment can be discharged. At the same time, by adjusting the fixed position of the outer cover to change the opening direction of the second opening, the propagation direction of residual sound can be changed, thereby minimizing the influence on the user.

Description

Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a charging pile noise reduction cover. Background Technology

[0002] Portable electric vehicle charging equipment, as an important energy replenishment device for new energy vehicles, is gradually becoming a common choice for users' daily charging due to its portability and flexibility. However, during operation, the internal electronic components of the charging station (such as transformers, cooling fans, relays, etc.) generate a certain amount of noise, which can affect the user experience. In addition, the noise problem is more significant under high-speed heat dissipation or high-power charging conditions, and the generated noise may even exceed the regulatory requirements for the noise level of electronic equipment. Summary of the Invention

[0003] The purpose of this application is to provide a noise-reducing cover for charging piles to solve the problem of excessive noise in existing charging piles.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] This application provides a noise reduction cover for a charging pile, including:

[0006] An outer cover defines a cavity having adjacent first and second openings.

[0007] A sound-absorbing pad layer covers the inner wall of the outer casing to absorb sound;

[0008] Mounting components are used to securely install the outer cover at the air inlet and outlet of the charging device.

[0009] In this design, the outer casing is fixedly installed at the air inlet and outlet of the charging device using mounting hardware, ensuring that the first opening completely covers the air inlet and outlet. Sound propagates through the first opening into the outer casing cavity and is absorbed by the sound-absorbing layer covering the inner wall of the outer casing, effectively reducing sound propagation from the charging device. To prevent the outer casing from blocking the air inlet and outlet of the charging device, thus hindering heat dissipation, the cavity of this design also has a second opening adjacent to the first opening. This second opening allows heat from the air inlet and outlet of the charging device to be dissipated. Furthermore, by adjusting the fixing position of the outer casing to change the opening direction of the second opening, the direction of residual sound propagation can be altered, thereby minimizing the impact on the user.

[0010] Optionally, the mounting component is a magnetic strip, and a magnetic strip fixing seat is provided on the inner wall of the first opening port, and the magnetic strip is fixedly mounted on the magnetic strip fixing seat.

[0011] Optionally, the magnetic strip is located on one side of the opening direction of the first opening relative to the magnetic strip holder, and the end face of the magnetic strip on the opening direction side of the first opening is on the same plane as the port of the first opening.

[0012] In this design, the outer cover is magnetically attached to the outer wall of the charging device, making installation and removal much easier. No complicated installation steps or tools are required, significantly improving the versatility and flexibility of the noise muffler. In this design, the magnetic strip is positioned relative to the magnetic strip holder on one side of the opening direction of the first opening, and the end face of the magnetic strip on this side is on the same plane as the port of the first opening. This ensures that when the magnetic strip is attracted to the outer wall of the charging device, the port of the first opening simultaneously adheres to the outer wall, effectively preventing noise leakage from the connection point and improving the noise reduction effect.

[0013] Optionally, it also includes a fixing component, which includes a pressure plate and a fixing bolt. The pressure plate is disposed on the side of the sound-absorbing pad layer away from the inner wall of the outer cover, and the screw end of the fixing bolt passes through the pressure plate and the sound-absorbing pad layer and is connected to the outer cover.

[0014] Optionally, there are multiple pressure plates, and the multiple pressure plates are arranged in parallel.

[0015] This design uses pressure plates to apply pressure to the sound-absorbing pad, ensuring it adheres tightly to the inner wall of the outer casing and preventing displacement or detachment during use. The bolts of the fixing bolts pass through the pressure plates and the pad to connect to the outer casing, thus securing the pressure plates, pad, and casing together to form a stable, integrated structure. Multiple parallel pressure plates further strengthen the fixation of the pad, ensuring it evenly covers the inner wall surface of the outer casing and preventing wrinkles, deformation, or displacement during use.

[0016] Because sound-absorbing pads age over time, they need to be replaced periodically. In this solution, when the sound-absorbing pad needs replacement, simply loosen the fixing bolts, remove the pressure plate, and the aged sound-absorbing pad can be easily removed from the inner wall of the outer casing. Then, replace it with a new sound-absorbing pad, reinstall the pressure plate, and tighten the fixing bolts. This solution greatly simplifies the sound-absorbing pad replacement process, reducing maintenance costs and time.

[0017] Optionally, the sound-absorbing pad layer is made of polyurethane foam.

[0018] Optionally, the surface of the polyurethane foam has a uniformly distributed raised structure.

[0019] The uniformly distributed raised structure increases the surface area of ​​the polyurethane foam, allowing more sound waves to come into contact with the sound-absorbing material. When sound waves propagate to the surface of the raised structure, more reflection and scattering paths are formed between the raised areas, further enhancing the propagation and absorption of sound waves within the sound-absorbing material.

[0020] Compared with existing technologies, the beneficial effects achieved by this application are as follows: When used, the outer cover is fixedly installed at the air inlet and outlet of the charging device using mounting components, so that the first opening completely covers the air inlet and outlet. Sound propagates into the cavity of the outer cover through the first opening and is absorbed by the sound-absorbing electrical layer covering the inner wall of the outer cover, thereby effectively reducing the sound propagation of the charging device. To avoid the outer cover blocking the air inlet and outlet of the charging device, which would prevent heat dissipation inside the charging device, the cavity of this application also has a second opening adjacent to the first opening, through which heat from the air inlet and outlet of the charging device can be dissipated. At the same time, by adjusting the fixing position of the outer cover to change the opening direction of the second opening, the propagation direction of residual sound can be changed, thereby minimizing the impact on the user.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0028] Example 1

[0029] This embodiment describes a noise reduction cover for a charging pile, referencing... Figures 1 to 4 In this embodiment, the charging pile noise muffler includes an outer cover 1. The outer cover 1 is the main structure of the noise muffler, and it is detachably fixed to the air inlet and outlet of the charging device 5 by means of mounting parts 3. The outer cover 1 defines a cavity for containing and guiding the propagation of sound. The cavity has a first opening 11, through which sound propagates into the cavity of the outer cover 1. The inner wall of the outer cover 1 is covered with a sound-absorbing pad layer 2 for absorbing the sound entering the cavity. The sound-absorbing pad layer 2 is made of a material with sound-absorbing properties, such as a porous material or a fibrous material. In this embodiment, the sound-absorbing pad layer 2 is made of polyurethane foam, and the surface of the polyurethane foam has a uniformly distributed raised structure. The uniformly distributed raised structure increases the surface area of ​​the polyurethane foam, allowing more sound waves to come into contact with the sound-absorbing material. When sound waves propagate to the surface of the raised structure, more reflection and scattering paths are formed between the raised structures, further enhancing the propagation and absorption of sound waves inside the sound-absorbing material.

[0030] In use, the outer cover 1 is fixedly installed at the air inlet and outlet of the charging device 5 using the mounting component 3, so that the first opening 11 can completely cover the air inlet and outlet. Sound propagates into the cavity of the outer cover 1 through the first opening 11 and is absorbed by the sound-absorbing electrical layer covering the inner wall of the outer cover 1, thereby effectively reducing the sound propagation of the charging device 5.

[0031] To prevent the outer casing 1 from blocking the air inlet and outlet of the charging device 5, thus hindering heat dissipation inside the charging device 5, this embodiment also includes a second opening 12 adjacent to the first opening 11. The second opening 12 allows heat from the air inlet and outlet of the charging device 5 to be dissipated. Simultaneously, by adjusting the fixed position of the outer casing 1 to change the opening direction of the second opening 12, the propagation direction of residual sound can be altered, thereby minimizing the impact on the user.

[0032] Example 2:

[0033] Based on the same inventive concept as Embodiment 1, refer to Figure 2In this embodiment, the outer cover 1 is magnetically attached to the outer wall of the charging device 5. Specifically, a magnetic stripe fixing seat 13 is provided on the inner wall of the first opening 11, and the magnetic stripe is fixedly mounted on the magnetic stripe fixing seat 13. The magnetic stripe defines a countersunk hole, and the magnetic stripe is mounted on the magnetic stripe fixing seat 13 by countersunk screws. Further, the magnetic stripe is located on the opening direction side of the first opening 11 relative to the magnetic stripe fixing seat 13, and the end face of the magnetic stripe on the opening direction side of the first opening 11 is on the same plane as the port of the first opening 11.

[0034] In this embodiment, the outer cover 1 is magnetically attached to the outer wall of the charging device 5, making it easier to install and remove. No complicated installation steps or tools are required, greatly improving the versatility and flexibility of the noise muffler. In this embodiment, the magnetic strip is located on the side of the opening direction of the first opening 11 relative to the magnetic strip fixing base 13, and the end face of the magnetic strip on the opening direction side of the first opening 11 is on the same plane as the port of the first opening 11. This ensures that when the magnetic strip is attracted to the outer wall of the charging device 5, the port of the first opening 11 can simultaneously adhere to the outer wall of the charging device 5, effectively preventing noise leakage from the connection point and improving the noise reduction effect.

[0035] This embodiment also includes a fixing component 4, which includes a pressure plate 41 and fixing bolts 42. The pressure plate 41 is made of galvanized steel and is positioned on the side of the sound-absorbing pad 2 facing away from the inner wall of the outer cover 1. The screw end of the fixing bolt 42 passes through the pressure plate 41 and the sound-absorbing pad 2 and is threadedly connected to the outer cover 1. In this embodiment, the pressure plate 41 applies pressure to the sound-absorbing pad 2, ensuring that the sound-absorbing pad 2 adheres tightly to the inner wall of the outer cover 1, preventing displacement or detachment during use. The screw end of the fixing bolt 42 passes through the pressure plate 41 and the sound-absorbing pad 2 and connects to the outer cover 1, thereby fixing the pressure plate 41, the sound-absorbing pad 2, and the outer cover 1 together to form a stable overall structure.

[0036] Furthermore, in this embodiment, there are multiple pressure plates 41, which are arranged in parallel. The multiple parallel pressure plates 41 make the sound-absorbing pad layer more firmly fixed, ensuring that the sound-absorbing pad layer 2 can evenly cover the inner wall surface of the outer cover 1, and avoiding problems such as wrinkles, deformation or displacement of the sound-absorbing pad layer 2 during use.

[0037] Because the sound-absorbing pad 2 will age with long-term use, it needs to be replaced periodically. When it is necessary to replace the sound-absorbing pad 2, simply loosen the fixing bolt 42, remove the pressure plate 41, and the aged sound-absorbing pad 2 can be easily removed from the inner wall of the outer cover 1. Then, replace it with a new sound-absorbing pad 2, reinstall the pressure plate 41, and tighten the fixing bolt 42. This embodiment greatly simplifies the replacement process of the sound-absorbing pad 2, reducing maintenance costs and time.

[0038] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
