Description

Technical Field

[0001] The utility model relates to the technical field of silencer equipment, in particular to an assembled automobile silencer. Background Art

[0002] With the improvement of living standards, people's needs for material things increase. Cars have entered thousands of households as consumer goods. For a car, brakes are an important system to ensure people's driving safety. Cars often make harsh noises when braking, which will cause people's discomfort. Therefore, in order to eliminate the braking noise, silencers are installed on the brake pads. The noise will change from the friction lining to the rigid back strength, and will change again from the rigid back to the silencer. The layers of resistance avoid resonance and play a role in reducing noise. However, the silencing effect of the existing silencer is not very ideal, and the silencer is not firmly installed on the brake pad. Therefore, an assembled automobile silencer is needed to improve the above problems.

[0003] The application number is 202223408155.8, which discloses an assembled automobile sound-absorbing sheet, including a metal layer, a first adhesive layer is arranged on the upper side of the metal layer, a first sound-absorbing layer is installed on the top of the first adhesive layer, and a second adhesive layer is arranged on the upper side of the first sound-absorbing layer. By arranging the first sound-absorbing layer and the second sound-absorbing layer in an assembled automobile sound-absorbing sheet, the honeycomb holes in the sound-absorbing layer are used to reflect the sound multiple times, and the sound is weakened each time it is reflected until the sound is eliminated, thereby solving the problem that the sound-absorbing effect of the sound-absorbing sheet is not very ideal. By arranging bolts on the metal layer, the first adhesive layer, the first sound-absorbing layer, the second adhesive layer, the second sound-absorbing layer and the third adhesive layer are connected to the brake pad in sequence by bolts for assembly, and nuts are used to tighten them to solve the problem that the sound-absorbing sheet is not firmly installed, thereby improving the practicality of the sound-absorbing sheet and making the sound-absorbing sheet have a better use effect.

[0004] Although bolts are arranged on the metal layer in this arrangement, and the first adhesive layer, the first sound-absorbing layer, the second adhesive layer, the second sound-absorbing layer and the third adhesive layer are sequentially connected to the brake pad for assembly by bolts, and nuts are used to tighten the brake pad to solve the problem of weak installation firmness of the sound-absorbing pad, thereby improving the practicality of the sound-absorbing pad and making the sound-absorbing pad have better use effect, the nuts and bolts of this arrangement are located between the installation grooves. According to the structural drawings of this arrangement, the installation groove space gap is small, and the operating space for the nuts and bolts is small. In addition, the sound-absorbing structure cannot be disassembled and replaced without tools.

[0005] Therefore, it is necessary to improve the installation structure of the silencer plate. Utility Model Content

The role of the inclined grooves is that when the sound waves are conducted to the upper surface of the first plate, the inclined grooves are symmetrically inclined at an angle, and are arranged in equal numbers to form a corrugated structure. The corrugated structure helps to reflect and absorb the sound waves multiple times, thereby playing a role of sound absorption and noise reduction.
