[0033] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the automobile body hole sound insulation sealing structure of the utility model in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 8 As shown, an embodiment of the utility model provides a sound insulation and sealing structure for holes in a vehicle body, comprising a sound insulation part 300 for soundproofing the vehicle body, and a positioning part 400 installed on one side of the sound insulation part 300 for fixing the sound insulation part 300, and a vehicle body outer shell 100 and a vehicle body inner shell 200 are arranged on both sides of the sound insulation part 300, respectively, and the positioning part 400 fastens and fixes the vehicle body outer shell 100, the vehicle body inner shell 200 and the sound insulation part 300, and the positioning part 400 is installed inside a mounting hole 210 fixed on the side of the vehicle body inner shell 200.

[0035] The positioning portion 400 includes a first mounting member 410 and a second mounting member 420 for installation and positioning. A fastener 430 for fastening the first mounting member 410 and the second mounting member 420 is movably installed on the upper end of the second mounting member 420. A sealing member 440 for sealing the first mounting member 410, the second mounting member 420 and the fastener 430 is movably inserted inside the fastener 430. The bottom of the first mounting member 410 is fixedly installed on the inner side of the vehicle body shell 100, the bottom of the second mounting member 420 is sealed and bonded to the sound insulation portion 300, and the second mounting member 420 passes through the vehicle body inner shell 200 and is fixed by the fastener 430 movably installed externally.

[0036] The lower end of the fastener 430 is threadedly installed in the inner cavity of the second mounting member 420 and matches with the threaded hole opened in the inner cavity of the second mounting member 420 .

[0037] The upper end of the first mounting member 410 is provided with a tightening head 411 for squeezing and fixing the internal sealing member 440. The upper end of the tightening head 411 is evenly provided with adjustment grooves 412 for tightening and fixing the tightening head 411. The first mounting member 410, the second mounting member 420 and the fastener 430 are all hollow. The sealing member 440 is inserted into the groove opened inside, and the sealing member 440 extends to the tightening head 411 for installation.

[0038] When the sound insulation part 300 is installed and fixed, the first mounting member 410 can be fixedly installed at the position to be fixed on the body shell 100, and then the second mounting member 420 is fixed to the sound insulation part 300, and then the body inner shell 200 is passed through, and then the sealing member 440 is installed in the fastener 430, and then the fastener 430 is rotated and installed in the second mounting member 420. When the body shell 100, the body inner shell 200 and the sound insulation part 300 are installed, the body shell 100 and the body inner shell 200 are insulated. Sound sealing can prevent excessive noise in the car, and the mounting hole 210 of the fixed part is sealed through the positioning part 400, and the sealing member 440 outside the positioning part 400 performs auxiliary sealing. At the same time, when the fastener 430 is rotated for tightening, the lower end of the fastener 430 tightens the end of the first mounting member 410, thereby clamping the sealing member 440. The operation is simple, the installation and disassembly are convenient, the sealing member 440 is prevented from falling off, and the connection is firm. At the same time, the T-shaped sealing member 440 can assist in sound insulation sealing to achieve a better sealing effect.

[0039] The sealing member 440 may be made of a silicone material, which can effectively provide sound insulation protection for the positioning portion 400 and prevent the positioning portion 400 from being bumped and deformed.

[0040] The lower end of the fastener 430 is inclined, the upper end of the tightening head 411 is inclined, and the inclination angles of the two groups of components match. The fastener 430 is installed in close proximity to the tightening head 411. When the fastener 430 is rotated and tightened, the fastener 430 moves downward in close proximity to the tightening head 411, thereby tightening the tightening head 411 inward, making it easier to fix the seal 440.

[0041] A support tube 421 for support is provided inside the second mounting member 420, and the support tube 421 is inserted into the mounting hole 210 for support. The outside of the support tube 421 is made of silicone material, and it can be sealed with the vehicle body inner shell 200 by tools such as sealant. The second mounting member 420 made of elastic material is snap-fitted and installed with the vehicle body inner shell 200. The support tube 421 made of elastic silicone material can facilitate the installation of the second mounting member 420 through the sound insulation part 300 and the vehicle body inner shell 200, and the operation is simple. At the same time, the elastic silicone material can play a certain sealing role, and the effect is better.

[0042] Adsorption magnets 441 are installed inside the seal 440 and at the bottom of the first mounting member 410, and the two groups of adsorption magnets 441 are magnetically attracted to each other, which are used to assist the installation of the seal 440 to ensure that the seal 440 fits the bottom of the first mounting member 410 when it is inserted into the first mounting member 410 and tightened to avoid loosening.

[0043] The sound insulation part 300 includes a mounting frame 310 for supporting and fixing, and a sound insulation component 340 arranged inside the mounting frame 310 for soundproofing the vehicle body shell 100 and the vehicle body inner shell 200. The sound insulation component 340 can be made of PU sponge, and a cotton felt part 350 is attached to the inside of the sound insulation component 340. A grid part 360 is arranged on one side of the cotton felt part 350 by adhesive. A filling cavity 370 is arranged inside the grid part 360, and the inside is used to fill with foam material.

[0044] A sound insulation member 340 made of PU sponge is arranged in the sound insulation part 300, which can effectively isolate sound. At the same time, a filling cavity 370 is set inside the sound insulation member 340, and the interior is filled with foaming material for sound insulation, which effectively improves the sound insulation effect. The outside of the filling cavity 370 is supported by the cotton felt part 350 and the mesh part 360, ensuring the filling space of the foaming material.

[0045] A waterproof layer 320 is arranged on the outer side of the mounting frame 310, and a corrosion-resistant layer 330 is fixedly arranged on the inner side of the mounting frame 310. The waterproof layer 320 can be made of a polyurethane material, and the corrosion-resistant layer 330 can be made of a glass fiber material. The exterior of the mounting frame 310 can be waterproofed to prevent rainwater from entering the interior of the mounting frame 310. The corrosion-resistant layer 330 is provided to protect the internal equipment to prevent corrosion of components from affecting the use effect.

[0046] The working principle of a sound insulation sealing structure for a hole in a car body is as follows: when the sound insulation part 300 is installed and fixed, the first mounting member 410 can be fixedly installed at the position to be fixed on the car body shell 100, and then the second mounting member 420 is fixed to the sound insulation part 300, and then the sealing member 440 is installed into the fastener 430, and then the fastener 430 is rotated and installed into the second mounting member 420. When the car body shell 100, the car body inner shell 200 and the sound insulation part 300 are installed, the car body shell 100, the car body inner shell 200 and the sound insulation part 300 are installed. The inner shell 200 is soundproofed and sealed in the middle to prevent excessive noise inside the car, and the mounting hole 210 of the fixed part is sealed through the positioning part 400. The seal 440 outside the positioning part 400 performs auxiliary sealing. At the same time, when the fastener 430 is rotated for tightening, the lower end of the fastener 430 tightens the end of the first mounting part 410, thereby clamping the seal 440. The operation is simple, and the installation and disassembly are convenient, which prevents the seal 440 from falling off and provides a stable connection. At the same time, the T-shaped seal 440 can assist in soundproofing and sealing to achieve a better sealing effect.

[0047] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
