Abstract
The utility model discloses a sound insulator of an engine access cover at the bottom of a carriage. The technical scheme of the sound insulator of the engine access cover at the bottom of the carriage is that the sound insulator is composed of a frame sectional material, plastic flooring, bamboo flooring, a steel plate, an aluminum trim strip, sound-absorbing cotton and an aluminum plate mesh. The plastic flooring, the bamboo flooring and the steel plate are sequentially arranged in the frame sectional material from top to bottom. The top surface of the aluminum trim strip is fixed on the bottom surface of the steel plate, the sound-absorbing cotton is filled in the aluminum trim strip, the aluminum plate mesh is fixed on the bottom surface of the aluminum trim strip, and a sealing rubber strip is fixed on the side wall of the aluminum trim strip. The sound insulator of the engine access cover at the bottom of the carriage has good effects of sound insulation, heat insulation and sealing. The test results show that the noise at the bottom in the carriage can be reduced by 1dB (A) or so.
Description
Technical field
The utility model relates to The automobile noise control equipment, relates in particular to a kind of passenger car bottom tune-up lid sound arrester.
Background technology
Along with people are more and more higher to the requirement of driving comfort, in the passenger vehicle design, all considered the sound insulation problem of passenger car bottom.Because structural limitations and certain demand, a whole antidrum panel can not be adopted in the passenger car bottom, but combine at grade by the member of different materials, different size, different noise insulation factors, the most weak component affecting that insulated against sound of the noise insulation factor behind the various component compositions is bigger.Acoustic survey for many vehicle cars bottom finds, the sound insulation property at access cover place a little less than, so direct defening effect that influences the car load bottom.
The utility model content
The purpose of this utility model is for solving floor sound insulation, heat insulation, sealing problem in the compartment, a kind of passenger car tune-up lid sound arrester being provided.
The technical scheme of the utility model passenger car tune-up lid sound arrester is: described device is made up of frame section bar, flooring laminate, bamboo floor, steel plate, aluminium layering, acoustical cotton and aluminium expanded sheets, described flooring laminate, bamboo floor, steel plate are set in turn in the frame section bar from top to bottom, the aluminium layering end face is fixed in the steel plate bottom surface, fill acoustical cotton in the aluminium layering, the aluminium layering bottom surface is aluminium expanded sheets fixedly, aluminium layering sidewall fixing seal adhesive tape.
Thread-forming screw passes sound arrester from top to bottom and links to each other with the access opening pedestal, and packing ring and rubber cradle are set between thread-forming screw and the sound arrester.
Described acoustical cotton bottom is pasted with reflective aluminium foil.
Described aluminium expanded sheets bottom periphery fixing seal ring.
The utility model automobile bottom tune-up lid sound arrester can play sound insulation, heat insulation, sealing function preferably.Test result shows that compartment inner bottom part noise can descend about 1dB (A).
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, automobile bottom tune-up lid sound arrester comprises frame section bar 1, packing ring 2, thread-forming screw 3, rubber cradle 4, flooring laminate 5, bamboo floor 6, steel plate 7, acoustical cotton 8, aluminium expanded sheets 9, seal ring 10, aluminium layering 11, sealing joint strip 12; Flooring laminate 5, bamboo floor 6 and steel plate 7 are pasted together by glue, fix by frame section bar 1; Aluminium layering 11 end faces are fixed on the steel plate 7 by rivet, and the inside sound absorption of packing into is cotton 8, and reflective aluminium foil is pasted on the acoustical cotton bottom, and aluminium expanded sheets 9 is fixed on the aluminium layering 11, described aluminium expanded sheets bottom periphery fixing seal ring 10, aluminium layering sidewall fixing seal adhesive tape 12; Thread-forming screw 3 passes sound arrester from top to bottom and links to each other with the access opening pedestal, and packing ring 2 and rubber cradle 4 are set between thread-forming screw and the sound arrester.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineering staff make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
