Description

Technical Field

[0001] This utility model relates to the field of vehicle sound insulation, specifically a vehicle sound insulation and noise reduction structure. Background Technology

[0002] A workshop is the basic unit for organizing production within an enterprise. It consists of several work sections or production teams and has the necessary factory buildings or sites, machinery and equipment, tools, and a certain number of production personnel, technical personnel, and management personnel to complete production tasks. Various equipment, devices, or products can be manufactured within the workshop.

[0003] When implementing traditional soundproofing and noise reduction structures in workshops, the inventors discovered at least the following unresolved issues in existing technologies: 1. Typically, workshop soundproofing and noise reduction are achieved using soundproofing panels. A large workshop is divided into several smaller workshop spaces using these panels, isolating noise generated within each space. However, traditional soundproofing structures are usually composed of relatively simple components, resulting in weak soundproofing and noise reduction effects and limited practicality; 2. Most workshop soundproofing panels are also large in area due to the large space of the workshop itself. This makes transportation and installation inconvenient due to their large size. Installation requires initial fixing or manual support of the large soundproofing panels before overall installation, which is quite cumbersome. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a vehicle sound insulation and noise reduction structure to solve the technical problem that the current single sound insulation panel structure cannot fully reduce sound insulation and noise.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a vehicle sound insulation and noise reduction structure is designed, including a mounting base, a sound insulation board between the mounting bases, a sound insulation plate on the outside of the sound insulation board, a sound-absorbing plate fixedly connected to the outside of the sound insulation plate, a sound reflector plate covering the outside of the sound insulation plate, a sound-absorbing ball fixedly connected to the surface of the sound reflector plate, and receiving cavities opened on both sides of the sound insulation board, with the sound insulation plate embedded inside the receiving cavity.

[0006] Preferably, a cross-shaped groove is formed inside the receiving cavity, and an adhesive sheet is embedded inside the cross-shaped groove. An insert is provided on the back of the sound insulation plate, and the insert is connected to the adhesive sheet by adhesive bonding.

[0007] Preferably, the surface of the sound insulation plate is provided with a sleeve, the back of the sound reflector is fixedly connected to a plug rod, the inside of the sleeve is provided with a slot, and the plug rod is inserted into the slot inside the sleeve.

[0008] Preferably, the mounting base has a slot inside, and the top and bottom of the sound insulation panel are provided with a retaining strip. The retaining strip is embedded in the slot. The mounting base is fixedly connected to the side of the mounting plate. The surface of the mounting plate has a mounting hole. The inner side of the mounting base is provided with a threaded rod. The retaining strip has a through hole inside, and the threaded rod passes through the through hole. The surface of the threaded rod is connected to an anti-loosening nut by a thread.

[0009] Preferably, the mounting base has an insert plate inside, and the side of the clip has a slot, into which the insert plate is inserted.

[0010] Preferably, the sound-absorbing spheres are hemispherical, and the sound-absorbing panels are equidistantly distributed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by installing separate sound insulation panels on both sides of the sound insulation panel, multiple sound-absorbing panels on the sound insulation panels, and sound-reflecting panels combined with sound-absorbing balls, greatly improves the noise reduction and sound isolation effect of the sound insulation structure. First, the sound-absorbing balls absorb sound; second, the sound-reflecting panels reflect some of the noise; and finally, the sound insulation panels combined with the sound insulation panel achieve the final sound isolation, thus achieving excellent sound insulation and noise reduction effect, significantly improving the sound insulation performance in the workshop, and is highly practical.

[0013] 2. This utility model features a modular mounting base at both the top and bottom of the sound insulation panel, with mounting plates on the sides of the mounting bases. This eliminates the need to install the entire sound insulation structure at once. Instead, the mounting positions and holes of the two mounting bases are determined first. The mounting plates are then fixed to the ceiling and floor of the workshop using fasteners, thus securing the mounting bases. Since the top and bottom of the sound insulation panel have locking strips, the strips are aligned with the slots on the mounting bases and inserted. The threaded rods on the sides of the mounting bases then pass through the locking strips. Finally, the anti-loosening nuts are tightened onto the threaded rods to complete the installation and fixing of the sound insulation panel. The entire installation process does not require initial fixing or support of the entire sound insulation structure. This segmented installation method significantly reduces installation difficulty and makes the operation simple and quick. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A vehicle sound insulation and noise reduction structure, see [link / reference] Figures 1 to 4 The structure includes a mounting base 1, a sound insulation panel 20 between the mounting bases 1, a sound insulation board 11 on the outside of the sound insulation panel 20, a sound-absorbing board 13 fixedly connected to the outside of the sound insulation board 11, and a sound-reflecting board 16 covering the outside of the sound insulation board 11. Due to the presence of the sound-reflecting board 16, it can not only reduce noise but also reflect sound, thus possessing strong functionality. Sound-absorbing balls 17 are fixedly connected to the surface of the sound-reflecting board 16. Receiving cavities 9 are opened on both sides of the sound insulation panel 20, and the sound insulation board 11 is embedded inside the receiving cavity 9. In practical application, because each side of the sound insulation panel 20 is equipped with a separate sound insulation board 11, multiple sound-absorbing boards 13 on the sound insulation board 11, and the sound-reflecting board 16 combined with the sound-absorbing balls 17, the combination of these four elements greatly improves the noise reduction and sound isolation effect of the sound insulation structure, significantly enhancing the sound insulation performance in the workshop and demonstrating strong practicality.

[0021] For details, see Figure 3 and Figure 4 The cavity 9 has a cross groove inside, and an adhesive piece 10 is embedded inside the cross groove. The back of the sound insulation panel 11 has a block 12. The block 12 is connected to the adhesive piece 10 by adhesive bonding. With the provided adhesive piece 10, the connection can be completed by simply aligning the block 12 with the adhesive piece 10 and pressing them together. This makes it easy to install and fix the sound insulation panel 11, and the operation is relatively convenient.

[0022] Further, see Figure 4The surface of the sound insulation panel 11 is provided with a sleeve 14, and the back of the sound reflector 16 is fixedly connected to the insertion rod 15. The sleeve 14 has a slot, and the insertion rod 15 is inserted into the slot inside the sleeve 14. Since the insertion rod 15 adopts a ninety-degree bending structure, when installing the sound reflector 16, it is only necessary to insert it into the inside of the sleeve 14 from top to bottom, and the installation of the sound reflector 16 can be completed. The whole installation process is relatively easy.

[0023] It is worth noting that, see Figure 2 The mounting base 1 has a slot 4 inside. The top and bottom of the sound insulation panel 20 are equipped with retaining strips 7, which are embedded in the slot 4. The mounting base 1 is fixedly connected to the mounting plate 2 on its side. Mounting holes 3 are formed on the surface of the mounting plate 2. A threaded rod 18 is provided on the inner side of the mounting base 1. A through hole 8 is formed inside the retaining strip 7, and the threaded rod 18 passes through the through hole 8. An anti-loosening nut 19 is connected to the surface of the threaded rod 18 via threads. Because the sound insulation panel 20 has a combined mounting base 1 at both the top and bottom, the entire sound insulation structure does not need to be installed during installation; only the initial location needs to be determined. The mounting positions and holes of the upper and lower mounting bases 1 are fixed to the top and ground of the workshop respectively with fasteners. This completes the fixing of the mounting bases 1. Then, simply align the retaining strip 7 with the retaining groove 4 of the mounting base 1 and insert the retaining strip 7 into the retaining groove 4. At this time, the threaded rod 18 on the side of the mounting base 1 will pass through the retaining strip 7. Then, tighten the anti-loosening nut 19 on the threaded rod 18 to complete the installation and fixing of the sound insulation panel 20. The entire installation process does not require initial fixing or support of the entire sound insulation and noise reduction structure. The segmented installation method greatly reduces the installation difficulty.

[0024] It is worth noting that, see Figure 4 The mounting base 1 has an insert plate 5 inside, and the side of the clip 7 has a slot 6. The insert plate 5 is inserted into the slot 6. During installation, the insert rod 15 is embedded into the slot 6, which can improve the connection strength between the mounting base 1 and the clip 7 and make the connection more stable.

[0025] It is worth mentioning that, see Figure 3 The sound-absorbing ball 17 is hemispherical, and the sound-absorbing plate 13 is equidistantly distributed. The working principle and benefits are that the multiple sound-absorbing balls 17 can absorb noise to a certain extent before sound insulation and noise reduction, which is highly functional.

[0026] When applying this noise reduction structure, the first step is to install the sound insulation structure. Since the entire structure consists of two sets of mounting bases 1 and a sound insulation panel 20, and the mounting bases 1 and the sound insulation panel 20 use a modular splicing structure, it is only necessary to first fix the mounting bases 1. First, determine the installation positions of the upper and lower mounting bases 1 and the corresponding mounting holes 3 of the mounting plate 2. Then, use fasteners to fix the mounting plate 2 to the ceiling and ground of the workshop, thus completing the fixing of the mounting bases 1. Since there are retaining strips 7 at the top and bottom of the sound insulation panel 20, simply align the retaining strips 7 with the retaining grooves 4 of the mounting base 1 and insert them into the grooves 4. At this time, the threaded rod 18 on the side of the mounting base 1 will pass through the retaining strip 7. Then, tighten the anti-loosening nut 19 onto the threaded rod 18 to complete the installation and fixing of the sound insulation panel 20. The entire installation process does not require preliminary... The entire sound insulation and noise reduction structure is fixed or supported using a segmented installation method, which greatly reduces the installation difficulty and makes the operation simple and quick. During the implementation of this sound insulation and noise reduction structure, separate sound insulation panels 11, multiple sound-absorbing panels 13 on the sound insulation panels 11, and independent sound-reflecting panels 16 combined with sound-absorbing balls 17 on their surfaces are installed on both sides of the main sound insulation panel 20. The combination of these four elements significantly improves the noise reduction function and sound isolation effect of the sound insulation structure. First, the sound-absorbing balls 17 absorb sound; second, the sound-reflecting panels 16 reflect some of the noise; and finally, the sound insulation panels 11 combined with the main sound insulation panel 20 achieve the final sound isolation. Furthermore, since the sound insulation panels 11, sound-absorbing panels 13, and sound-reflecting panels 16 are all double-sided, they achieve excellent sound insulation and noise reduction effects, significantly improving the sound insulation performance in the workshop and demonstrating strong practicality during implementation.
