Abstract
A heat insulation and sound insulation structure for a passenger car engine compartment comprises two layers of plastic flooring, a layer of bamboo floor, a layer of sound insulation rubber plate, three layers of 40 mm heat insulation and sound insulation cotton with aluminium foils, a layer of galvanized plate, two layers of 8 mm heat insulation fireproof cotton with aluminium foils and a layer of perforated aluminium screen plate. According the heat insulation and sound insulation structure for the passenger car engine compartment, two layers of 30 mm heat insulation and sound insulation cotton on a middle layer of an original framework are replaced by the three layers of 40 mm heat insulation and sound insulation cotton with the aluminium foils, and the heat insulation and sound insulation effect is improved; original three layers of 35 mm heat insulation cotton with aluminium foils are replaced by the two layers of 8 mm heat insulation fireproof cotton with the aluminium foils, the heat insulation effect of the engine compartment is greatly improved, the fireproof performance is greatly improved, and the original maintaining space of the engine compartment is increased by 29 mm. The number of the heat insulation and sound insulation layers is also increased to 13 from the original 11, and the heat insulation and sound insulation effect is better.
Description
Technical field
The utility model relates to technical field of engineering machinery, is specifically related to that a kind of engine cabin of passenger car is heat insulation, acoustic construction.
Background technology
Original coach five people seats are put and are existed noise large, and machinery space is overheated to passenger zone, and machinery space fire retardancy is poor.Available technology adopting heat-insulating sound-insulating structure as shown in Figure 1 solves the problems referred to above, and it is mainly made up of flooring laminate (2 layers) 1, bamboo floor (1 layer) 2, rubber slab for noise deadening (1 layer) 3,30mm heat-insulating sound-insulating cotton (2 layers) 4, galvanized plate (1 layer) 5,35mm band aluminium foil heat insulation foam (3 layers) and punching aluminium web plate (1 layer).Although such structure can play certain sound-insulating and heat-insulating effect, because engine compartment temperature is high, noise is large, this structural heat-insulation soundproof effect is general, and fire resistance is poor, its space taking is large simultaneously, has correspondingly reduced the space for maintenance of machinery space, is not easy to maintenance.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind ofly can optimize sound-insulating and heat-insulating effect, promote fire resistance and increase that the engine cabin of passenger car of machinery space space for maintenance is heat insulation, acoustic construction.
The technical solution of the utility model is: engine cabin of passenger car is heat insulation, acoustic construction, comprise 2 layers of flooring laminate, 1 layer of bamboo floor, 1 layer of rubber slab for noise deadening, 3 layers of 40mm band aluminium foil heat-insulating sound-insulating cotton, 1 layer of galvanized plate, 2 layers of 8mm band aluminium foil heat-insulating, fire-preventing cotton, 1 layer of punching aluminium web plate, described flooring laminate is positioned on bamboo floor, rubber slab for noise deadening is positioned on the below on bamboo floor, 3 layers of 40mm are laid on the below of rubber slab for noise deadening with aluminium foil heat-insulating sound-insulating cotton, galvanized plate is positioned on the below of end one deck 40mm with aluminium foil heat-insulating sound-insulating cotton, 2 layers of 8mm are laid on the below of galvanized plate with aluminium foil heat-insulating, fire-preventing cotton, punching aluminium web plate is positioned on the below of end one deck 8mm with aluminium foil heat-insulating, fire-preventing cotton.
Advantage of the present utility model: 2 layers of 30mm heat-insulating sound-insulating cotton of former skeleton interlayer are replaced by 3 layers of 40mm band aluminium foil heat-insulating sound-insulating cotton by the utility model, increased heat insulation and soundproof effect; 3 layers of original 35mm band aluminium foil heat insulation foam are changed to two-layer 8mm band aluminium foil heat-insulating, fire-preventing cotton, not only greatly promoted the effect of heat insulation of machinery space, and greatly promoted fire resistance, and made original machinery space space for maintenance increase 29mm; The heat-insulating sound-insulating number of plies has also been increased to 13 layers, heat-insulating sound-insulating better effects if by original 11 layers.
Brief description of the drawings
Fig. 1 is heat insulation in prior art, acoustic construction schematic diagram.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Now in conjunction with the following drawings, utility model is described in detail.
Referring to Fig. 2, engine cabin of passenger car described in the utility model is heat insulation, acoustic construction, comprise 9,1 layer of punching aluminium web plate 7 of 5,2 layers of 8mm band aluminium foil heat-insulating, fire-preventing cotton of 8,1 layer of galvanized plate of 3,3 layers of 40mm band aluminium foil heat-insulating sound-insulating cotton of 2,1 layer, 1,1 layer of bamboo floor of 2 layers of flooring laminate rubber slab for noise deadening, described flooring laminate 1 is positioned on bamboo floor 2, rubber slab for noise deadening peace 3 is below bamboo floor 2,3 layers of 40mm are laid on the below of rubber slab for noise deadening 3 with aluminium foil heat-insulating sound-insulating cotton 8, galvanized plate 5 is positioned on the below of end one deck 40mm with aluminium foil heat-insulating sound-insulating cotton 8; 2 layers of 8mm are laid on the below of galvanized plate 8 with aluminium foil heat-insulating, fire-preventing cotton 9, punching aluminium web plate 7 is positioned on the below of end one deck 8mm with aluminium foil heat-insulating, fire-preventing cotton 9.Beat glue encapsulation process in the border of galvanized plate, in increasing sealing, effectively isolated thermal source, sound pollution source, thus promote heat-insulating sound-insulating effect.The utility model can be widely used in tourist coach, long-distance bus five people's platform heat-insulating sound-insulating structures, can obviously promote like this traveling comfort, the safety that passenger takes, and save well energy consumption.
