Description

Technical Field

[0001] The utility model relates to the technical field of automobile sound insulation, in particular to an automobile sound insulation sponge which can be easily spliced. Background Art

[0002] Car sound insulation is based on the performance of the vehicle, the corresponding road conditions, and the conditions of use. It carefully deals with the engine noise generated by the car, the resonance sound of the tires and the road surface, and the friction sound caused by the gaps or aging of components in the car due to the squeezing force, etc., in order to improve the comfort of the car. Sound insulation composite sponge is a common sound insulation material.

[0003] Sound insulation boards cannot block sounds of all frequencies. Objects have inherent resonant frequencies. The sound insulation effect of sound insulation boards is significantly reduced for sounds close to the resonant frequency of the objects. The sound insulation effect of sound insulation boards alone is relatively limited. When installing them on cars, due to the complex environment, they need to be cut into the required size by slitting, which will produce large scraps that cannot be used, resulting in a waste of damping sound insulation boards. In addition, the cutting is complicated. When the sound insulation sponges are connected to each other, either gaps will be left to reduce the sound insulation effect, or the overlapping of the sound insulation sponges will increase the thickness. For this reason, we propose a car sound insulation sponge that is easy to splice. Utility Model Content

The sound insulation effect of relying solely on the sound insulation board is relatively limited, and reducing vibration will make the noise smaller.

[0024] Among them, a rubber pad 7 is arranged on the upper side wall of the inner cavity of the slide groove 5, and the slide rail 6 is slidably installed in the inner cavity of the slide groove 5. The rubber pad 7 fits the slide rail 6, and the rubber pad 7 fills the gap between the outer frame 1 to improve the sound insulation effect. The sound insulation sponge 2 includes: a sound absorbing sponge layer, a sound insulation board, a waterproof layer and a shock-absorbing pad. The sound insulation board is installed on the top of the shock-absorbing pad, the sound absorbing sponge layer is installed on the top of the sound insulation board, and the waterproof layer is installed on the top of the sound absorbing sponge layer. The waterproof layer can prevent the sound absorbing sponge layer from absorbing water and causing damage, and the shock-absorbing pad reduces vibration transmission. The first connecting plate 3 and the second connecting plate 4 are identical mirror-image devices. A groove 9 is provided on the right side of the second connecting plate 4, a slider 10 is provided on the left side of the second connecting plate 4, and sealing pads 13 are provided at the left and right edges of the second connecting plate 4. A screw 11 is provided on the upper end of the side elevation of the second connecting plate 4, and a screw 11 is provided on the lower end of the second connecting plate 4. There are screw holes 12, and the first connecting plate 3 and the second connecting plate 4 are slidably buckled, which makes the connection between the sound insulation sponges quick and convenient, and also makes the sound insulation sponges have good sealing and good sound insulation effect. The mounting frame 16 is fixedly connected to the outer frame 1, and the rotating shaft 19 is installed on the side elevation of the mounting frame 16. A connecting block 20 is rotatably installed on the rotating shaft 19, and the pull rod 17 is rotatably installed on the connecting block 20.

The vibration energy between the shock absorbing devices 8 is transmitted to each other and lost, thereby further reducing the noise transmission.

[0025] Working principle: The sound insulation board cannot block sounds of all frequencies. Objects have inherent resonant frequencies. The sound insulation effect of the sound insulation board is significantly reduced for sounds close to the resonant frequency of the object. The sound insulation effect of the sound insulation board alone is relatively limited. The device installs a shock absorbing device 8 on the rear side facade of the outer frame 1. The damping spring 14 on one side of the shock absorbing device 8 collapses, and after the collapse, the pull rod 17 is pulled to change. The pull rod 17 pulls the other side to cause the opposite deformation. The vibration energy between the shock absorbing devices 8 is transmitted to each other and lost, which further reduces the vibration and enhances the sound insulation. Due to the complex environment, it needs to be cut into the required size by cutting. The size of the outer frame 1 is too small to be used, which will result in a large amount of scrap material that cannot be used, resulting in a waste of damping sound insulation panels, and the cutting is complicated. The device is provided with a slide groove 5 on the top surface of the outer frame 1 and a slide rail 6 on the bottom surface. The position between each section can be freely adjusted as needed to achieve a close fit. When the sound insulation sponges are connected to each other, either gaps will be left to reduce the sound insulation effect, or the overlapping of the sound insulation sponges will increase the thickness. The device is provided with a first connecting plate 3 and a second connecting plate 4 on the left and right sides of the outer frame. The first connecting plate 3 and the second connecting plate 4 are slidably buckled, which makes the connection between the sound insulation sponges quick and convenient, and also makes the sound insulation sponges have good sealing and good sound insulation effect.
