Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1-2, the utility model discloses an outer coupling subwoofer of car and automobile body seal installation structure of embodiment includes outer coupling subwoofer 1, sealing washer 2 and car panel beating 3. The out-of-vehicle coupled subwoofer 1 includes a sound outlet 11, a mounting point 12, and an exhaust port 13. The automobile sheet metal 3 has an opening 31. The mounting point 12 is fixed with the metal plate in the vehicle and used for fixing the external coupling subwoofer 1 in the vehicle. The sealing ring 2 is integrally formed at the exhaust port 13 of the exterior coupling subwoofer 1, and the exterior coupling subwoofer 1 is mounted on the automobile sheet metal 3 in a manner that the exhaust port 13 and the sealing ring 2 are embedded in the opening 31.
In the present embodiment, the exhaust port 13 has an annular outer wall and a plurality of vent holes in the annular outer wall, through which gas generated in the subwoofer 1 coupled outside the vehicle is discharged to the outside. The cross section of the annular outer wall may be a circular ring, a rectangular ring, or the like, and in the present embodiment, the cross section of the annular outer wall is a rectangular ring, and correspondingly, the opening 31 is also formed in a rectangular shape. The sealing ring 2 is also formed into a rectangular ring, and the sealing ring 2 is wrapped outside the annular outer wall of the exhaust port 13 and is integrally injection-molded with the annular outer wall of the exhaust port 13. The sealing ring 2 can be an EPDM, TPE, TPU or silica gel sealing ring.
The annular outer wall of the exhaust port 13 and the sealing ring 2 are embedded in an opening 31 of the automobile sheet metal 3 in an interference fit mode, the opening 31 is communicated with the external environment, and gas generated in the external coupling subwoofer 1 is exhausted to a vent hole and is exhausted to the external environment such as the atmosphere through the opening 31. The sealing ring 2 wraps the outer wall of the exhaust port 13 and is used for preventing gas generated in the external coupling subwoofer 1 from flowing into a gap between the automobile sheet metal 3 and the annular outer wall from a vent hole and flowing back to the inside of the automobile. Since the grommet 2 prevents the gas generated in the subwoofer 1 coupled outside the vehicle from flowing back into the vehicle, the grommet 2 can also reduce the noise generated thereby.
In the present embodiment, as shown in fig. 3, a plurality of convex portions 131 are formed on the outer periphery of the annular outer wall of the exhaust port 13, a concave portion 21 fitted to the convex portion of the exhaust port 13 is formed on the inner periphery of the gasket 2, and the exhaust port 13 and the gasket 2 are integrally injection-molded so that the convex portions 131 of the exhaust port 13 and the concave portion 21 of the gasket 2 are fitted to each other. By providing the convex portion 131 on the outer annular wall of the exhaust port 13 and the concave portion 21 fitted to the inner annular wall of the gasket 2, the contact area between the exhaust port 13 and the gasket 2 can be increased, and the connection strength between the exhaust port 13 and the gasket 2 can be increased. Further, the protrusions are arranged at equal intervals along the outer circumference of the annular outer wall of the exhaust port 13, so that the outer circumference of the annular outer wall of the exhaust port 13 is formed in a zigzag structure. Of course, a plurality of concave portions 21 may be formed on the outer periphery of the annular outer wall of the exhaust port 13, and a convex portion 131 fitted to the concave portion 21 of the exhaust port 13 may be formed on the inner periphery of the gasket 2, and the exhaust port 13 and the gasket 2 may be integrally molded such that the concave portion 21 of the exhaust port 13 and the convex portion 131 of the gasket 2 are fitted to each other.
To sum up, because sealing washer 2 integrated into one piece is in gas vent 13 of outer coupling subwoofer 1, installing the utility model discloses an outer coupling subwoofer does not need the staff to assemble the sealing washer to the gas vent through manual when outer coupling subwoofer and automobile body seal installation structure, and the outer coupling subwoofer integral erection who will install the sealing washer is to the opening of car panel beating again, consequently the utility model discloses an outer coupling subwoofer and automobile body seal installation structure convenient assembling because sealing washer 2 integrated into one piece is in outer coupling subwoofer 1's gas vent 13, can avoid the risk that the sealing washer part turned up from the outer wall of gas vent 13 moreover.
