Summary of the invention
The utility model purpose is to improve the deficiency of existing technology, and a kind of evaporation fan that is used for automotive air-conditioning system is provided, with noise that reduces the motor oscillating generation and the Electro Magnetic Compatibility that improves motor.
For achieving the above object, the utility model adopts following technological scheme:
A kind of car air conditioner evaporation fan; It is centrifugal single shaft blower fan; Comprise motor assembly; The other end that one end of said motor assembly connects the base of shell, said motor assembly connects wind wheel through motor fixing frame, and said motor assembly comprises from base to the wind wheel of shell successively: end cap sub-assembly, brush carrier plate sub-assembly, armature sub-assembly and casing sub-assembly have shock-damping structure between said motor assembly and the said shell; Said shock-damping structure comprises two-part: first portion is arranged at the base of shell and the beam between the motor assembly, and second portion is the shock ring that is arranged between motor assembly and the motor fixing frame.
Further; Said shock-damping structure can also comprise third part, and this third part is the shock-damping structure that is arranged on the said brush carrier plate sub-assembly, and this shock-damping structure has projection; Said projection be arranged on the bayonet fittings on the casing sub-assembly, so that brush carrier plate sub-assembly is fixed on the casing sub-assembly.
Further, said shock-damping structure can the preferred rubber shock-damping structure.
Further, said brush carrier plate sub-assembly can also comprise the brush carrier plate and be integrated in the electromagnetic compatibility module on the brush carrier plate.
The advantage of the technological scheme that the utility model adopted is:
(1) through changing the fit of motor assembly and plastic casing, in the middle of motor assembly and shell, increases the rubber shock-absorbing structure, make motor assembly and being connected of shell pass through shock-damping structure, can reduce the vibration and the noise of blower fan running;
(2) the brush holder plate with motor is fixed on the shell through the projection on the rubber structure, the noise that can reduce motor oscillating effectively and produce with working of plastics resonance;
(3) through optimizing electromagnetic compatibility structure Design mode, be integrated into the electromagnetic compatibility module on the brush holder plate of motor assembly, can effectively shield the electromagnetic interference of blower fan, satisfy the high standard requirement of automobile electric appliance system;
(4) through being integrated into the electromagnetic compatibility module on the brush holder plate of motor assembly, can be in the ability that improves anti-electromagnetic interference, the production of convenient reality assembling;
(5) noise of blower fan is low, electromagnetic compatibility is effective; Motor is easy for installation, and the manufacturing efficiency of blower fan improves.

Embodiment
Below in conjunction with accompanying drawing the enforcement and the advantage of the utility model are done further to explain.
Referring to Fig. 1.The utility model car air conditioner evaporation fan is centrifugal single shaft blower fan, comprises motor assembly 4, and an end of said motor assembly 4 connects the base 1 of shell (not label), the other end of said motor assembly 4 connects wind wheel 6 through motor fixing frame 5.Has shock-damping structure 10 between said motor assembly 4 and the said shell; Said shock-damping structure 10 comprises two-part: first portion is arranged at the base 1 of shell and the beam 2 between the motor assembly 4, and second portion is the shock ring 9 that is arranged between motor assembly 4 and the motor fixing frame 5.
Said shock-damping structure 10 can the preferred rubber shock-damping structure, like beam 2 preferred rubber beams.
Referring to Fig. 2.Said motor assembly 4 comprises from base 1 to the wind wheel 6 of shell successively: end cap sub-assembly 41, brush carrier plate sub-assembly 42, armature sub-assembly 43 and casing sub-assembly 44; Said brush carrier plate sub-assembly 42 comprises brush carrier plate 421, is integrated in the electromagnetic compatibility module 423 on the brush carrier plate 421 and is arranged at the block rubber 422 on the brush carrier plate 421.Said block rubber 422 can have two, is arranged at the two ends of brush carrier plate 421 respectively.Have projection on the said block rubber 422, said projection cooperates with bayonet socket 442 on being arranged on casing sub-assembly 44, so that brush carrier plate sub-assembly 42 is fixed on the casing sub-assembly 44.
Referring to Fig. 3.During installation, motor assembly 4 is connected through shock-damping structure 10 with the base 1 of shell, the wind wheel 6 of the single shaft blower fan of motor assembly 4 is fixed through the axle interference fit that wind wheel mounting hole and motor stretch out, and at axle head through the fixing wind wheel of back-up ring 7 and back-up ring 8.Back-up ring 7 can be a jump ring with back-up ring 8.The end cap sub-assembly 41 of motor assembly 4 can be connected and fixed through screw 3 with the assembling of casing sub-assembly 44.When blower fan energising operation, rotor begins to rotate operation, drives wind wheel 6 and produces air flow, and rubber shock-absorbing structure 10 plays cushioning effect, effectively reduces the noise that vibrations cause.The startup of built-in EMC module can mask the interference that motor produces, for vehicle-mounted other electrical equipment provide good working environment.
