In the process of moving also can Self generating oscillations reversed can all be transmitted to and by road injustice bring random vibration
On automobile air conditioning system, to aggravate vibration of compressor, increases the risk of pipeline fracture in automobile air conditioning system, reduce automobile air conditioning system operation
Reliability.The footing 120 of damping assembly 100 of the invention is installed on bottom plate 110 by electromagnetic susceptor 130, utilizes electromagnetism base
The electromagnetic principle of seat 130 forms magnetic field, and footing 120 is suspended setting under the influence of a magnetic field, reduction footing 120 and bottom
The hard contact of plate 110.Since magnetic field has certain equivalent stiffness and damping, vibrational energy can be increased in this way in footing
Transmitting loss on 120, effectively inhibits the vibration of compressor 200 to transmit by footing 120 to the vehicle body of car, and then reduce and make an uproar
The radiation of sound improves comfort level when passenger takes；Meanwhile influence of the car random vibration to compressor 200 is reduced, inhibit
Transmitting of the vibration of car to compressor 200, avoids compressor 200 and pipeline from being broken down by transient impact, guarantees pressure
Balance when contracting machine 200 is run then improves the reliability of compressor 200, enables on-board air conditioner even running.This hair
Bright damping assembly 100 makes the suspension setting of footing 120 of compressor 200 by electromagnetic susceptor 130, reduces footing 120 and bottom
The hard contact of plate 110, it is suppressed that the vibration of compressor 200 is transmitted to the vehicle body of car, similarly reduces the random of car
Vibrate influence to compressor 200, the vibration of effective solution compressor 200 be transmitted on car caused noise problem and
Car random vibration passes to the problem of aggravation compressor 200 caused by damping assembly 100 vibrates, and improves relaxing when passenger takes
Appropriateness improves the reliability of damping assembly 100, so that 200 even running of compressor.
As an embodiment, electromagnetic susceptor 130 includes electromagnetism footstock 131, electromagnetic base 132 and electromagnetism attachment base
133.Electromagnetism footstock 131 and electromagnetic base 132 are oppositely arranged and are formed placed cavity, and electromagnetism attachment base 133 connects electromagnetism footstock 131
With electromagnetic base 132.Footing 120 is suspended in placed cavity.That is, electromagnetic base 132, electromagnetism footstock 131 and electromagnetism connect
It is arranged between joint chair 133 in concave shape, placed cavity is then the cavity of concave shape.Since electromagnetic susceptor 130 can generate magnetic field force,
Placed cavity is then field region, and the direction of magnetic field force is vertical direction.In this way, footing 120 is installed in placed cavity, magnetic field force energy
It is suspended in footing 120 in the field region of electromagnetic susceptor 130, to reduce the hard contact of footing 120 Yu bottom plate 110.This
The damping assembly 100 of invention is mainly the vibration that compressor 200 is balanced using the magnetic field force that electromagnetic susceptor 130 generates, so that
Footing 120 is suspended in placed cavity, since magnetic field has certain equivalent stiffness and damping, can reduce footing 120 and bottom plate
110 hard contact, increase vibration footing 120 transmitting lose, and then inhibit compressor 200 vibration to car transmit with
And the random vibration of car is inhibited to transmit to compressor 200, reduce noise radiation, improves comfort when passenger takes, improve
100 reliability of operation of damping assembly.
Electromagnetic base 132 is fixedly installed on bottom plate 110, and play, Jin Erbao occurs to avoid the position of electromagnetic susceptor 130
The reliability for demonstrate,proving the fixed footing 120 of electromagnetic susceptor 130 guarantees that compressor 200 runs smoothly.Preferably, in the present embodiment, electricity
Magnetopause seat 131 is located at the top of electromagnetic base 132, and the opening direction of placed cavity is towards compressor 200.It in this way can be convenient for pressure
The installation of the footing 120 of contracting machine 200 improves assembly efficiency.Meanwhile electromagnetism footstock 131 with electromagnetic base 132 is setting up and down can also
Enough it is convenient for the generation in magnetic field, footing 120 is facilitated to be suspended in placed cavity.Also, electromagnetism footstock 131 and electromagnetism footstock 131 can also
The position for enough limiting footing 120, avoids compressor 200 from generating violent vibration and exceed electromagnetism footstock 131 and electromagnetism footstock
131, guarantee 200 even running of compressor, improves the reliability of damping assembly 100.
Further, there are prepsetting gaps between footing 120 and the inner wall of placed cavity.Electromagnetic susceptor 130 is in placed cavity
After generating magnetic field, prepsetting gap can be suspended in placed cavity convenient for footing 120, to reduce the hardness of footing 120 Yu bottom plate 110
Contact, the transmitting for increasing vibration in footing 120 is lost, and then inhibits the vibration of compressor 200 that visitor is transmitted and inhibited to car
The random vibration of vehicle is transmitted to compressor 200, reduces noise radiation, is improved comfort when passenger takes, is improved damping assembly
100 reliabilities of operation.
Still further, compressor 200 has multiple footings 120, and, the quantity of electromagnetic susceptor 130 is equal to footing 120
Quantity.Each footing 120 is installed on bottom plate 110 by the electromagnetic susceptor 130 of corresponding position.In the present embodiment, compressor
There are four footing 120, compressors 200 to be connect by four footings 120 with bottom plate 110 for 200 tools, to guarantee that compressor 200 is fixed
Reliably, avoid the position of compressor 200 that play occurs and influences the reliability service of compressor 200.Also, four footings 120 divide
Not Dui Ying an electromagnetic susceptor 130 so that footing 120 suspend setting, reduce footing 120 and bottom plate 110 hard contact, increase
The transmitting vibrated in footing 120 is lost, and then inhibits the vibration of compressor 200 that the random vibration of car is transmitted and inhibited to car
Trend compressor 200 transmits.Certainly, multiple electromagnetic susceptors 130 or integral structure.It can be convenient for electromagnetic susceptor in this way
130 assembly.
Further, electromagnetism footstock 131, electromagnetic base 132 and electromagnetism attachment base 133 are structure as a whole.It is integrated
Electromagnetism footstock 131, electromagnetic base 132 and electromagnetism attachment base 133 can save assembly process, improve production efficiency, while can also
Enough guarantee the reliability of electromagnetic susceptor 130.
As an embodiment, damping assembly 100 further includes locating part 140, and locating part 140 successively wears electromagnetism top
Seat 131, footing 120 and electromagnetic base 132.Locating part 140 can limit footing 120 along the translation of bottom plate 110.Due to compressor
200 be horizontal setting in on-board air conditioner, also, since the footing of compressor 200 120 is to suspend to be set in placed cavity,
Footing 120 can have the possibility axially moved in placed cavity, i.e. footing 120 is moved along the surface of bottom plate 110.
It will affect the reliability service of compressor 200 in this way.Therefore, damping assembly 100 of the invention increases the present footing of locating part 140
120 axial movement.In the present embodiment, locating part 140 is axial bayonet lock.In other embodiments of the invention, locating part
140 be pillar or other can wear electromagnetism footstock 131, footing 120 and electromagnetic base 132 to limit the axial fortune of footing 120
Dynamic structure.Specifically, can be fixedly connected with locating part 140 with footing 120, there is no connect for locating part 140 and electromagnetic susceptor 130
Connect relationship；It can also be fixedly connected with locating part 140 with electromagnetic susceptor 130, connection relationship is not present in locating part 140 and footing 120.
