Description
Technical field
The utility model belongs to electric drilling match technical field of structures, and in particular to a kind of motor sound insulation shield.
Background technique
Motor sound insulation shield is the product in automobile engine using new energy resources cabin, is generally being wrapped in motor periphery, motor is opening
When dynamic, howling is issued, generates noise.So being badly in need of a kind of its product for arriving sound insulation, sound-absorbing of energy, package sound insulation is carried out to it.
The prior art is mainly that acoustical cotton is arranged on top cover in enging cabin, and soundproof effect is highly effective, applicability and practical
Property is restricted.
Summary of the invention
Reasonable and strong applicability the motor sound insulation shield the purpose of the utility model is to provide a kind of structure setting.
The technical solution for realizing the utility model aim is a kind of motor sound insulation shield, including arc cover, the arc-shaped cover
It uniformly fixes fluted in the middle part of the inner wall of body, is uniformly fixed with bit-avoiding slot in the inner wall lower of the arc cover and buckles convex
Block is uniformly fixed with heat dissipation bar groove in the upper inside wall of the arc cover, in the connection of the heat dissipation bar groove and the groove
Place is fixed with locating convex block, and the arc cover includes nonwoven layer, the EVA surface layer at middle part and the PU of the inside foaming in outside
Layer, the groove, heat dissipation bar groove, bit-avoiding slot, buckle convex block and locating convex block are arranged in PU foaming layer.
There is magic paste layer in the outside cementation of the non-woven fabrics, the non-woven wraps are admittedly on motor and pass through velcro
It is fixed.
The nonwoven layer with a thickness of 1-5mm and grammes per square metre is 80g/m2-400g/m2, the EVA layer with a thickness of
1-3mm and grammes per square metre are 150g/m2-5400g/m2.
The PU foaming layer is that isocyanates (A material) and polyether polyol (B material) are poured through high pressure or low-pressure casting is in EVA
It is formed on layer.
The density of the PU foaming layer is 50kg/m3 to 200kg/m3.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, and it is convenient to operate, and is provided with recessed
Slot, buckle convex block and locating convex block, can effectively and quickly be connected to motor, while having preferable sound insulation and noise reduction performance, make
With reliable and stable, strong applicability and practicability is good.
Detailed description of the invention
In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, in which:

Hot pressing is combined with each other, and is pressed and molded by baking.
There is magic paste layer 14 in the outside cementation of the non-woven fabrics, the non-woven wraps are admittedly on motor and pass through magic
Patch is fixed.
The nonwoven layer with a thickness of 1-5mm and grammes per square metre is 80g/m2-400g/m2, the EVA layer with a thickness of
1-3mm and grammes per square metre are 150g/m2-5400g/m2.
The PU foaming layer is that isocyanates (A material) and polyether polyol (B material) are poured through high pressure or low-pressure casting is in EVA
It is formed on layer.
The density of the PU foaming layer is 50kg/m3 to 200kg/m3.
The structure setting of the utility model is reasonable, and it is convenient to operate, and fluted, buckle convex block and locating convex block is arranged, can have
It imitates and is quickly connected to motor, while there is preferable sound insulation and noise reduction performance, use is reliable and stable, strong applicability and practicability
It is good.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
