Description
Technical field
The invention belongs to screw compressor technical field, the damping more particularly to a kind of electric scroll compressor for vehicles is dropped
It makes an uproar structure.
Background technique
Electric scroll compressor is one of the main noise component in New-energy electric vehicle, in order to reduce the shake of compressor
Dynamic and noise is usually improved from the noise vibration propagation path that compressor generates, such as in the installation branch of compressor
Resilient cushion is filled on frame, wraps up sound-proof material outside compressor or increases the methods of muffler on the suction air pipe of compressor
It reduces vibration and the noise of compressor, does not occupy very large space in this way, also increase cost.
Summary of the invention
The purpose of the present invention is to provide a kind of shock-reducing and noise-reducing structure of electric scroll compressor for vehicles, the damping noise reduction knots
Structure can reduce vibration when compressor is run and can reduce compressor and generate in increase rubber sleeve on the moving component of compressor
Noise, not only save cost and also save automobile front chamber arrangement space, have high use value.
The object of the present invention is achieved like this: a kind of shock-reducing and noise-reducing structure of electric scroll compressor for vehicles, including machine
Shell, end cap, Moving plate, fixed scroll, crankshaft, balance weight, pin, the cylindrical structure of the casing, the cabinet top
End cap is set, and the casing internal is provided with a sunk structure, and support is installed in the sunk structure bottom position of the casing
Moving plate is arranged in disk, the support plate top, and setting crankshaft is run through in the support plate, and the crankshaft upper end setting is flat
Weigh block, the bottom setting of the balance weight insertion Moving plate, fixed scroll is arranged inside the Moving plate, the balance weight is logical
Cross the upper end that pin is installed on crankshaft, rubber sleeve be set at the pin and balance weight contact position, the pin with
Rubber sleeve is set at crankshaft contact position.
Bearing is set at the support plate and crankshaft contact site.
The rubber sleeve mutually agrees with pin.
The pin deviates the axle center setting of crankshaft, and deviation distance is the 1/3 ~ 2/3 of crank throw.
The beneficial effect comprise that: the present invention increases rubber sleeve on this moving component of compressor pin can be with
The noise shaken and compressor generation can be reduced when compressor operation is reduced, cost is not only saved and also saves automobile front chamber
Arrangement space.
Detailed description of the invention
Fig. 1 is schematic diagram of internal structure of the invention.
Fig. 2 is the schematic perspective view at balance weight of the invention.
Fig. 3 is the vertical section structure schematic diagram of balance weight and crankshaft.
In figure: 1, casing 2, end cap 3, Moving plate 4, fixed scroll 5, crankshaft 6, balance weight 7, pin 8,
Support plate 9, rubber sleeve 10, bearing.
Specific embodiment
With reference to the accompanying drawing to the embodiment of the present invention further instruction.
Embodiment 1
As illustrated in the accompanying drawings from 1 to 3, a kind of shock-reducing and noise-reducing structure of electric scroll compressor for vehicles, including casing 1, end cap 2, Moving plate 3,
End cap is arranged at the top of the casing 1 in fixed scroll 4, crankshaft 5, balance weight 6, pin 7, the cylindrical structure of casing 1
2, the casing 1 is internally provided with a sunk structure, and support plate 8, institute are installed in the sunk structure bottom position of the casing 1
Moving plate 3 is arranged in 8 top of support plate stated, and setting crankshaft 5 is run through in the support plate 8, and 5 upper end of the crankshaft setting is flat
Weigh block 6, and the balance weight 6 is embedded in the bottom setting of Moving plate 3, and fixed scroll 4 is arranged inside the Moving plate 3, and described is flat
Weighing apparatus block 6 is installed on the upper end of crankshaft 5 by pin 7, and rubber sleeve 9 is arranged at the pin 7 and 6 contact position of balance weight,
Rubber sleeve 9 is set at the pin 7 and 5 contact position of crankshaft.
Bearing 10 is set at the support plate 8 and 5 contact site of crankshaft.
The rubber sleeve 9 agrees with 7 phase of pin.
The pin 7 deviates the axle center setting of crankshaft 5, and deviation distance is the 1/2 of 5 radius of crankshaft.
The present invention is when in use: a kind of shock-reducing and noise-reducing structure of electric scroll compressor for vehicles, including casing, end cap, dynamic
Disk, fixed scroll, crankshaft, balance weight, pin, at the contact position of balance weight and crankshaft on be pressed a pin, and in pin
Rubber sleeve is set at column and balance weight contact position, rubber sleeve is set at pin and crankshaft contact position, due to pin and rubber
The matching relationship of set limits the slewing area of balance weight, so that will not collide during balance weight and crankshaft operation, together
When increased rubber sleeve can reduce the vibrating noise of running gear.
Generally, the present invention has vibration when can reduce compressor operation and can reduce the noise of compressor generation
Advantage.
