Compare prior art's not enough point, the beneficial effects of the utility model are that:
through the enhancement layer, first sound absorbing layer and the second sound absorbing layer that set up, guaranteed to give sound insulation and fallen the intensity of board of making an uproar, can effectually guarantee to give sound insulation and fall the board of making an uproar and use, utilize first sound absorbing layer and second sound absorbing layer, can be better absorb engine noise, especially utilize corrugated container board and the sponge piece of packing, can strengthen the absorption effect to the noise. In order to guarantee that the vibrations of engine pass to the cabin cover, lead to the too big problem that leads to the board of making an uproar to fall that gives sound insulation of cabin cover vibrations, so be equipped with damping device in the bottom, guarantee the stability of cover through mutually supporting of backup pad, connecting rod, slider, damping spring and U type base plate, increase the life of the board of making an uproar to fall that gives sound insulation.
Drawings
Fig. 1 is a schematic view of a cross-sectional view of an embodiment of the present invention.
Detailed Description
The embodiment of the present invention will be further explained with reference to fig. 1.
A novel sound insulation and noise reduction plate for a car engine compartment cover comprises a reinforcing layer 1, wherein an isolation layer is arranged on the lower surface of the reinforcing layer 1, a first sound absorption layer 2 is arranged on the lower surface of the isolation layer, the first sound absorption layer 2 comprises a corrugated board and a sponge block 3 filled in the corrugated board, a second sound absorption layer 4 is arranged on the lower surface of the first sound absorption layer 2, a damping device is arranged on the lower surface of the second sound absorption layer 4, the damping device comprises a U-shaped base plate 5, a connecting rod 8, a sliding block 7, a damping spring 6 and a supporting plate 9, the bottom of the U-shaped base plate 5 is connected with the second sound absorption layer 4, the damping spring 6 is symmetrically arranged at the bottom of the U-shaped base plate 5 and is parallel to the bottom of the U-shaped base plate 5, one end of the damping spring 6 is fixed at one end of a side wall close to the bottom of the, the other end of the connecting rod 8 is movably connected with the middle of the supporting rod in an external mode, and the two ends of the supporting rod are connected with the inner side wall of the U-shaped substrate 5 in a sliding mode.
Through enhancement layer 1, first sound absorbing layer 2 and the second sound absorbing layer 4 that sets up, guaranteed to give sound insulation and fallen the intensity of board of making an uproar, can effectually guarantee to give sound insulation and fall the board of making an uproar and use, utilize first sound absorbing layer 2 and second sound absorbing layer 4, can be better absorb the engine noise, especially utilize corrugated container board and filled sponge piece 3, can strengthen the absorption effect to the noise. In order to ensure that the vibration of the engine is transmitted to the engine compartment cover to cause the problem that the sound insulation and noise reduction plate falls off due to overlarge vibration of the engine compartment cover, a damping device is arranged at the bottom, firstly, a U-shaped base plate 5 is fixed on the lower surface of a second sound absorption layer 4, then, damping springs 6 are symmetrically arranged at the bottom of the U-shaped base plate 5 and are parallel to the bottom of the U-shaped base plate 5, one end of each damping spring 6 is fixed at one end of the side wall close to the bottom of the U-shaped base plate 5, the other end of each damping spring is fixedly connected with one end of a sliding block 7, the other end of each sliding block 7 is rotatably connected with a connecting rod 8, each connecting rod 8 is movably connected with a supporting plate 9, when the vibration of the engine is transmitted to the supporting plates 9, the supporting plates 9 are forced to cause the supporting plates 9 to slide, lead to 7 horizontal slip compression damping spring 6 of slider, because damping spring 6 self elasticity gives 7 reaction forces of slider, finally transmit the backup pad 9 through connecting rod 8 on, play fine shock attenuation effect, increase the life of the board of making an uproar of falling that gives sound insulation simultaneously.
The reinforcing layer 1 is a glass wool layer which is formed by spirally winding a plurality of fibers in a clockwise direction in a three-dimensional crossing manner.
A plurality of fibers are crossed in a three-dimensional mode and are wound into the glass wool layer in a clockwise spiral mode, so that the strength of the glass wool layer is improved, and the sound insulation effect of the glass wool layer is improved.
The second sound absorbing layer 4 is a sound absorbing cotton layer.
The sound-absorbing cotton layer has a good sound-absorbing effect, is firm, tasteless and not rotten, does not add any auxiliary agent or adhesive in the production process, and is low in price and suitable for popularization and use.
The side wall of the U-shaped substrate 5 is provided with a limiting block 10, the fiber blocks are symmetrically arranged at the ports of the two side walls of the U-shaped substrate 5, and the supporting plate 9 slides between the bottom of the U-shaped substrate 5 and the limiting block 10.
In order to prevent the support plate 9 from sliding out of the inner side wall of the U-shaped substrate 5 due to self gravity, a limiting block 10 is arranged at an opening of the inner side wall of the U-shaped substrate 5 to prevent the support plate 9 from falling.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
