Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction equipment, in particular to a noise reduction device. Background Art

[0002] Noise reduction devices are devices that can reduce or eliminate noise in the environment. They are designed to provide a quieter and more comfortable environment to improve the experience of working, studying or resting. These devices can reduce the level of noise interference by absorbing, isolating, offsetting or converting noise.

[0003] For example, a Chinese utility model patent (CN220773518U) discloses a computer noise reduction device, which records: "The height of the fixed disk is adjusted by rotating the knob so that the mainframe case is located on a stable horizontal plane and tightly attached to it, making it stable without any shaking. The internal socket of the mainframe case is fixedly connected to the connecting column. Placing the connecting column in it will firmly jam it and reduce the sound. The sound-absorbing cotton installed on the bottom surface of the mainframe case can also more effectively soundproof, allowing users to reduce the noise of the machine while working, devote themselves to it, and complete their work more efficiently." It also records: "The device still has many problems. When existing computers are running, they often make noise due to unstable placement and unstable hard disk installation, which brings a bad experience to users and may even cause the machine to interrupt operation, seriously affecting work efficiency." Technical problems.

[0004] In summary, it can be seen that the prior art utilizes placing the computer case stably to reduce the vibration generated by its internal structure during operation and the noise caused thereby. However, this method has the following technical problems: the exterior of the computer case is mostly assembled with metal plates, and the sound insulation effect of the metal plates is mostly poor. Once the noise inside the computer case is generated, it is easy to spread to the outside of the case, thereby affecting the work efficiency of the user. For this reason, the present application proposes a noise reduction device to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

[0005] Based on this, it is necessary to provide a noise reduction device to address the above technical problems. When the noise inside the device shell is transmitted outward through the outside of the device shell, the noise passes through the device shell and the fixed shell to enter the interior of the fixed shell. The noise entering the fixed shell will be prevented from propagating by the fixed column and the limiting column. Part of the noise passes through layers of sound insulation boards. During this process, the noise is continuously reduced due to the absorption of the sound insulation boards and the noise reduction pads. After passing through a layer of sound insulation boards and noise reduction pads, the noise is separated by multiple partitions and bounced back in the space formed by two adjacent partitions, the noise reduction pad and the next sound insulation board, so that the noise is further weakened, avoiding the noise inside the device shell from being directly transmitted to the outside through the device shell, reducing the noise in the computer environment, and improving the user's work efficiency.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] As mentioned in the background art, the exterior of computer cases is mostly assembled from metal plates, and the metal plates have poor sound insulation effects. As a result, after noise is generated inside the computer case, it is easy to spread to the outside of the case, thereby affecting the work efficiency of users.

[0031] In order to solve this technical problem, the utility model provides a noise reduction device, which is used to reduce the noise inside a computer case from being transmitted to the outside and thus affecting the work of a user.

[0032] Specifically, please refer to Figure 1-Figure 3 , the noise reduction device specifically includes:

[0033] The device comprises a housing 1, a plurality of noise reduction mechanisms 3 are arranged outside the housing 1, an auxiliary mechanism 4 is arranged on the housing 1, and legs 2 are fixedly connected to the bottom and four corners of the housing 1;

[0034] The noise reduction mechanism 3 includes a fixed shell 5, a fixed column 6, a supporting component, a limiting component, and a noise reduction component. The fixed shell 5 is fixedly connected to the outer wall of the device shell 1, and the fixed column 6 is fixedly connected to the inner wall of the fixed shell 5.

[0035] The noise reduction device provided by the utility model, when the noise inside the device shell 1 is transmitted outward through the outside of the device shell 1, the noise passes through the device shell 1 and the fixed shell 5 to enter the interior of the fixed shell 5, and the noise entering the interior of the fixed shell 5 will be prevented from propagating by the fixed column 6 and the limiting column 7, and part of the noise passes through the layers of sound insulation boards 12. In this process, the noise is continuously reduced due to being blocked and absorbed by the sound insulation boards 12 and the noise reduction pads 14, and the noise is separated by multiple partition boards 15 after passing through a layer of sound insulation boards 12 and noise reduction pads 14, and is rebounded in the space formed by two adjacent partition boards 15 and the noise reduction pad 14 and the next sound insulation board 12, so that the noise is further weakened, and the noise inside the device shell 1 is prevented from passing through the device shell 1 directly to the outside, thereby reducing the noise in the computer environment and improving the user's work efficiency.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0038] Please refer to Figure 1-Figure 6 , a noise reduction device, comprising:

[0039] The supporting assembly includes a limiting column 7 fixedly connected to the inner wall of the fixed shell 5. There are multiple limiting columns 7, and multiple T-shaped slots 8 are respectively provided on both sides of a limiting column 7. The T-shape of the T-shaped slot 8 prevents the sound insulation board 12 from moving up, down, left and right, thereby improving the stability of the device.

[0040] The limiting component includes a fixed spring 9 fixedly connected to the inside of the limiting column 7. There are multiple limiting components, which are arranged on each T-shaped slot 8. One end of the fixed spring 9 is fixedly connected to a block 10. The fixed spring 9 is always in a compressed state during the operation of the device. The block 10 is slidably connected to the inner wall of the limiting column 7, and the front and rear sides of the block 10 are respectively provided with a first inclined surface 11.

[0041] The noise reduction component includes a sound insulation board 12, and the left and right sides of the sound insulation board 12 are respectively slidably connected to the two T-shaped slots 8 corresponding to the sides of two adjacent limiting columns 7 that are close to each other. The outside of the sound insulation board 12 is provided with a plurality of second inclined surfaces 13 that are adapted to the first inclined surfaces 11. A noise reduction pad 14 is fixedly connected to the side of the sound insulation board 12 away from the device housing 1. The noise reduction pad 14 can block and absorb noise. A plurality of partition plates 15 are fixedly connected to the side of the noise reduction pad 14 away from the sound insulation board 12. The partition plates 15 facilitate pulling the sound insulation board 12, thereby facilitating the disassembly of the sound insulation board 12, and at the same time separate the noise, so that the noise rebounds in the small spaces separated by the partition plates 15, thereby further reducing the transmission of noise to the outside.

[0042] Through the above structural design, after the structure inside the device housing 1 generates noise due to operation, the noise passes through the device housing 1 and the fixed housing 5 and enters the interior of the fixed housing 5. Part of the noise is blocked by the fixed column 6 and the limiting column 7 to reduce the noise. Another part of the noise first passes through a layer of sound insulation board 12 and noise reduction pad 14 to absorb the noise and reduce sound propagation. Then the noise is separated into different areas by a plurality of partition boards 15, thereby reducing the noise. The weakened noise collides and rebounds in the space formed by the two adjacent partition boards 15, the noise reduction pad 14 and the next sound insulation board 12, thereby further reducing the noise. The noise is further weakened, and the further weakened part passes through the next sound insulation board 12 and the noise reduction pad 14 to be weakened again. After multiple weakenings, it can pass through the fixed shell 5 to enter the outside. When the sound insulation board 12 needs to be disassembled, the first partition plate 15 is pulled, and the first inclined surface 11 is squeezed through the second inclined surface 13 on the sound insulation board 12, so that the block 10 is retracted into the interior of the limiting column 7. In this process, the fixed spring 9 is compressed. After the sound insulation board 12 is pulled out, it returns to its original position under the action of the elastic force of the fixed spring 9, and then the subsequent sound insulation boards 12 can be pulled out one by one for replacement or cleaning.

[0043] Embodiment 2:

[0044] The noise reduction device provided in Example 1 is further optimized. Specifically, Figure 7 As shown, the auxiliary mechanism 4 includes a plurality of mounting frames 16 fixedly connected to the inner wall of the device housing 1, and a plurality of mounting slots 17 are provided on one mounting frame 16. The size, number and position of the mounting slots 17 can be adjusted according to the requirements of installing different components to improve the applicability of the device.

[0045] The auxiliary mechanism 4 also includes a top cover 18, a fixing bolt 20 is inserted into the interior of the top cover 18, the bottom end of the fixing bolt 20 is threadedly connected to the inner wall of the device housing 1, a plurality of heat dissipation holes 19 are opened on the top of the top cover 18, and a filter sponge 21 is fixedly connected to the bottom of the top cover 18. The filter sponge 21 has a high density and can effectively block dust and debris. At the same time, due to its soft texture, it can also absorb and reduce the propagation of sound to a certain extent.

[0046] Through the above structural design, by removing the fixing bolts 20, the corresponding structure inside the device housing 1 can be fixed on the mounting frame 16 through the mounting groove 17. The noise generated by the components inside the device housing 1 during operation will be weakened by the filter sponge 21 and then transmitted to the outside through the heat dissipation holes 19 on the top cover 18.
