Description
Technical field
The utility model relates to auto sound technical field, in particular to a kind of automotive motor controller blimp.
Background technique
With the development of society, more and more ordinary people's familys are equipped with automobile.As automobile has become people
The indispensable vehicles, it is comfortable to drive the common recognition for having become numerous drivers.But it the mechanical oscillation of automobile and makes an uproar
Sound is the main reason for influencing driver's comfort level.
In electric car, the function of electric machine controller is instructed according to gear, throttle, brake etc., by power battery institute
Electric energy needed for the electric energy of storage is converted into driving motor, to control starting operation, the advance and retreat speed, climbing dynamics of electric vehicle
Etc. driving status, or will help electric vehicle brake, and by part brake energy storage into power battery.In motor control
Many noises will be generated in the operational process of device.
Currently, the sound insulation for electric machine controller is only simply wrapped with motor cover shell or using only sound-proof material
It wraps up in.These sound insulation modes are difficult to that medium-high frequency noise is isolated, to influence automobile global comfort.
Utility model content
The purpose of the utility model is to overcome the defect of the prior art and deficiencies, provide a kind of automotive motor controller
Blimp can effectively reduce the medium-high frequency noise of electric machine controller using composite sound insulation material, while reduce electric machine controller
Vibration, increase the service life of electric machine controller, improve the comfort level of motor vehicle operators.
In order to achieve the above object, the utility model uses following technical scheme:
Automotive motor controller blimp, the blimp are respectively arranged with damping layer, sound absorbing layer and sound insulation from inside to outside
Layer, the damping layer are bonded with sound absorbing layer, and the sound absorbing layer is bonded with puigging, the appearance of the damping layer and electric machine controller
Face paste is closed, and the shape in the space and electric machine controller that limit inside the blimp is adapted, and is offered on the blimp more
A mounting hole.The damping layer is foam.Foam have sound absorption properties, oil absorption, dust tightness and vibration reduction and cushioning effect, therefore in addition to
Sound insulation, foam can also enhance the protective effect to electric machine controller, and the material for being also beneficial to protection sound absorbing layer is not easy to be damaged.
The puigging is PVC sound insulating pad.PVC sound insulating pad has good sound insulation value.The sound absorbing layer is acoustical cotton.Acoustical cotton tool
There are good sound absorption qualities, can effectively reduce the noise of electric machine controller generation.The weight of the acoustical cotton is 720 grams to 880
Gram.The acoustical cotton of this weight range can both guarantee sound-absorbing quality and also can blimp size it is more appropriate.
The damping layer is bonded with sound absorbing layer by double-sided adhesive as a preferred technical solution,.
The sound absorbing layer is bonded with puigging by welding or thermal bonding process as a preferred technical solution,.
The utility model compared with prior art, has the following advantages and beneficial effects: the guarantor with ordinary motor controller
Shield shell phase ratio, the utility model uses composite sound insulation material, in conjunction with damping layer, sound absorbing layer and puigging, can reach sound insulation,
The effect of sound-absorbing and vibration damping increases making for electric machine controller to effectively reduce medium-high frequency noise and the vibration of electric machine controller
With the service life, the comfort level of motor vehicle operators is improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of blimp in the utility model embodiment
Fig. 2 is the perspective view of blimp in the utility model embodiment
Fig. 3 is the expanded view of blimp in the utility model embodiment
Fig. 4 is the sound absorption qualities comparison diagram of blimp and common sound insulation cotton material in the utility model embodiment
Detailed description of the invention: 1: damping layer, 2: sound absorbing layer, 3: puigging, 4: mounting hole, 5: blimp
Specific embodiment
The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model
Mode is without being limited thereto.
From Fig. 1,2,3 as can be seen that providing a kind of automotive motor controller blimp, institute in the utility model embodiment
It states blimp 5 and is respectively arranged with damping layer 1, sound absorbing layer 2 and puigging 3 from inside to outside.Damping layer 1 passes through two-sided with sound absorbing layer 2
Glue laminating.Sound absorbing layer 2 is bonded with puigging 3 by welding or thermosol attaching process.Refer to from inside to outside close to automobile
Electric machine controller is the internal layer of blimp, is the outer layer of blimp far from automotive motor controller.
Foam can be selected in 1 material of damping layer, and foam has sound absorption properties, oil absorption, dust tightness and vibration reduction and cushioning effect, therefore
In addition to sound insulation, foam can also enhance the protective effect to electric machine controller, be also beneficial to protection sound absorbing layer material be not easy by
Damage.
Acoustical cotton can be selected in 2 material of sound absorbing layer.Acoustical cotton has good sound absorption qualities, can effectively reduce electric machine controller
The noise of generation.Preferably, the weight of acoustical cotton is 720 grams to 880 grams.The acoustical cotton of this weight range can both guarantee to inhale
Sound quality also can blimp size it is more appropriate.
PVC sound insulating pad can be selected in puigging 3.PVC sound insulating pad has good sound insulation value.
The shape in the space and electric machine controller that limit inside blimp 5 is adapted, and multiple installations are offered on blimp
Hole 4.As shown in Fig. 2, the shape of electric machine controller is cuboid, then the shape of blimp space bound inside is cuboid.Every
