Larger noise can be produced, comfort level when affecting passenger to take, and then affect the ride experience of passenger.Meanwhile, big bus car
In the process of moving also can Self generating oscillations, and the random vibration that is brought by road injustice, all can be reverse be delivered to
On automobile air conditioning system, so as to aggravate vibration of compressor, increase the risk of pipeline fracture in automobile air conditioning system, reduce automobile air conditioning system operation
Reliability.The footing 120 of the damping assembly 100 of the present invention is installed on base plate 110 by electromagnetic susceptor 130, using electromagnetism base
The electromagnetic principle of seat 130 forms magnetic field so that footing 120 can be suspended settings under the influence of a magnetic field, reduction footing 120 and bottom
The hard contact of plate 110.As magnetic field has certain equivalent stiffness and damping, can so increase vibrational energy in footing
Transmission loss on 120, is effectively inhibited the vibration of compressor 200 to be transmitted to the vehicle body of car by footing 120, and then reduction is made an uproar
The radiation of sound, improves comfort level when passenger takes；Meanwhile, impact of the car random vibration to compressor 200 is reduced, is suppressed
Transmission of the vibration of car to compressor 200, it is to avoid compressor 200 and pipeline are subject to transient impact and break down, it is ensured that pressure
Balance when contracting machine 200 runs, improves the reliability of compressor 200 so that on-board air conditioner being capable of even running then.This
Bright damping assembly 100 causes the suspension of footing 120 of compressor 200 to arrange 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
Impact of the vibration to compressor 200, effectively solve compressor 200 vibration be delivered on car caused by noise problem and
Car random vibration passes to the problem of the aggravation vibration of compressor 200 caused by damping assembly 100, improves relaxing when passenger takes
Appropriateness, improves the reliability of damping assembly 100 so that 200 even running of compressor.
Used as a kind of embodiment, electromagnetic susceptor 130 includes electromagnetism footstock 131, electromagnetic base 132 and electromagnetism connecting seat
133.Electromagnetism footstock 131 is oppositely arranged and is formed placed cavity, the connection electromagnetism of electromagnetism connecting seat 133 footstock 131 with electromagnetic base 132
With electromagnetic base 132.Footing 120 is suspended in placed cavity.That is, electromagnetic base 132, electromagnetism footstock 131 and electromagnetism connect
Arrange in concave shape between joint chair 133, placed cavity cavity then for concave shape.As electromagnetic susceptor 130 can produce magnetic field force,
Placed cavity is then field region, and the direction of magnetic field force is vertical direction.So, footing 120 is installed in placed cavity, magnetic field force energy
Footing 120 is enough made to be suspended in the field region of electromagnetic susceptor 130, to reduce the hard contact of footing 120 and base plate 110.This
The damping assembly 100 of invention mainly uses the magnetic field force of the generation of electromagnetic susceptor 130 balancing the vibration of compressor 200 so that
Footing 120 is suspended in placed cavity, as magnetic field has certain equivalent stiffness and damping, can reduce footing 120 and base plate
110 hard contact, increase vibration footing 120 transmission lose, and then suppress compressor 200 vibration to car transmission with
And suppress the random vibration of car to transmit to compressor 200, reduce noise radiation, improve comfortableness when passenger takes, improve
100 reliability of operation of damping assembly.
Electromagnetic base 132 is fixedly installed on base plate 110, and play, Jin Erbao occur to avoid the position of electromagnetic susceptor 130
Card electromagnetic susceptor 130 fixes the reliability of footing 120, it is ensured that compressor 200 operates steadily.It is preferred that 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.Can so be easy to press
The installation of the footing 120 of contracting machine 200, improves efficiency of assembling.Meanwhile, electromagnetism footstock 131 with electromagnetic base 132 is setting up and down can also
Enough it is easy to the generation in magnetic field, facilitates footing 120 to be suspended in placed cavity.Also, electromagnetism footstock 131 can also with electromagnetism footstock 131
The position of footing 120 is enough limited, it is to avoid compressor 200 produces violent vibration and exceeds electromagnetism footstock 131 and electromagnetism footstock
131, it is ensured that 200 even running of compressor, improve the reliability of damping assembly 100.
Further, there is prepsetting gap between footing 120 and the inwall of placed cavity.Electromagnetic susceptor 130 is in placed cavity
After producing magnetic field, prepsetting gap can be easy to footing 120 to be suspended in placed cavity, rigid with base plate 110 to reduce footing 120
Contact, increase vibration are lost in the transmission of footing 120, and then suppress the vibration of compressor 200 to transmit to car and suppress visitor
The random vibration of car is transmitted to compressor 200, reduces noise radiation, is improved comfortableness when passenger takes, is improved damping assembly
100 reliabilities of operation.
Yet 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 base plate 110 by the electromagnetic susceptor 130 of correspondence position.In the present embodiment, compressor
200 have four footings 120, and compressor 200 is connected with base plate 110 by four footings 120, to ensure that compressor 200 is fixed
Reliable, it is to avoid the position of compressor 200 occurs play and affects the reliability service of compressor 200.Also, 120 points of four footings
Not Dui Ying an electromagnetic susceptor 130, so as to footing 120 suspends arrange, reduce the hard contact of footing 120 and base plate 110, increase
The transmission loss in footing 120 is vibrated, and then suppresses the vibration of compressor 200 to transmit to car and suppress shaking at random for car
Trend compressor 200 is transmitted.Certainly, multiple electromagnetic susceptors 130 can also be structure as a whole.Electromagnetic susceptor can be so easy to
130 assembling.
Further, electromagnetism footstock 131, electromagnetic base 132 and electromagnetism connecting seat 133 are structure as a whole.It is integrated
Electromagnetism footstock 131, electromagnetic base 132 and electromagnetism connecting seat 133 can save assembly process, and improve production efficiency, while can also
Enough ensure the reliability of electromagnetic susceptor 130.
Used as a kind of embodiment, damping assembly 100 also includes that locating part 140, locating part 140 wear electromagnetism top successively
Seat 131, footing 120 and electromagnetic base 132.Locating part 140 can limit translation of the footing 120 along base plate 110.Due to compressor
200 be horizontal be arranged in on-board air conditioner, also, due to the footing 120 of compressor 200 be suspend be arranged in placed cavity,
Can there is the possibility that axially moves, i.e. footing 120 in placed cavity and move along the surface of base plate 110 in footing 120.
The reliability service of compressor 200 can so be affected.Therefore, damping assembly 100 of the invention increases by 140 present footing of locating part
120 axially-movable.In the present embodiment, locating part 140 is axial bayonet lock.In other embodiments of the invention, locating part
140 be projection or other can wear electromagnetism footstock 131, footing 120 and electromagnetic base 132 and axially be transported with limiting footing 120
Dynamic structure.Specifically, can be fixedly connected with footing 120 with locating part 140, locating part 140 does not have company with electromagnetic susceptor 130
Connect relation；Can also locating part 140 be fixedly connected with electromagnetic susceptor 130, there is no annexation with footing 120 in locating part 140.
Can either so ensure that footing 120 is suspended in placed cavity, can limit the displacement of 120 horizontal direction of footing again, it is to avoid suspend
