The embodiment provides a magnetic suspension which is used for assembling a frame, supporting a power assembly and realizing non-contact efficient vibration isolation in a mode of electromagnetic field repulsion. In this embodiment, the number of the related magnetic levitation suspensions is multiple, so that multi-point stable support is realized.

Referring to fig. 1, 2 and 4, the magnetic levitation suspension is composed of an electromagnet 300 and a permanent magnet 400 that are oppositely disposed and a retractable support structure 200 that supports the electromagnet 300.

The electromagnet 300 is fixed on the telescopic end of the telescopic supporting structure 200, so that the electromagnet 300 can move along with the telescopic action of the telescopic supporting structure 200, and the supporting height of the electromagnet 300 and the supporting height of the power assembly 500 are adjusted.

Meanwhile, the supporting height of the power assembly 500 can be maintained through the supporting height of the telescopic supporting structure 200 and the extended physical contact support in the power failure condition. Meanwhile, under the condition of impact collision, the electromagnet 300 is powered off to eliminate a magnetic field, the telescopic supporting structure 200 is contracted, and the support power assembly 500 flows out of a falling space, so that the power assembly can fall from a vehicle body conveniently, and the situation that the power assembly rushes into a cabin is avoided, and the safety of personnel and equipment in the vehicle is threatened; and more buffer spaces are provided for safe collision, and the safety is improved.

The telescopic support structure 200 in the present embodiment assumes the functions of axial support and telescopic adjustment of the support height, and is capable of controlled telescopic action.

Specifically, referring to fig. 5, the retractable support structure 200 includes: base 210, drive motor, drive gear 220, drive rack 230, and electromagnet support 240.

The driving rack 230 is axially movably fixed on the base 210, the electromagnet support rod 240 is fixed on the driving rack 230, and the electromagnet 300 is fixed on the electromagnet support rod 240, so that the driving rack 230 is driven to drive the electromagnet support rod 240 to move, and the supporting height of the electromagnet 300 is adjusted.

In this embodiment, the base 210 is a supporting cylinder; the driving motor, the driving gear 220, the driving rack 230 and the electromagnet support rod 240 are all arranged in the support cylinder.

The support cylinder is provided with a fixing member 120 for fixing to the base 100.

Referring to fig. 1, the present embodiment provides a power assembly supporting apparatus for magnetically suspending a power assembly 500 based on the above-mentioned magnetic suspension.

Specifically, the powertrain support apparatus includes: a base 100 and a plurality of said magnetic levitation suspensions.

Referring to fig. 3, the base 100 is provided with a falling window 110, so that when collision and impact occur, the powertrain 50 can rapidly and smoothly fall out of the vehicle through the falling window 110, thereby avoiding rushing into the cabin and forming an impact buffering space.

The plurality of magnetic levitation suspensions are fixed on the base 100, and the plurality of magnetic levitation suspensions are arranged around the falling window 110; and the plurality of magnetic levitation suspensions apply an obliquely upward supporting moment above the drop window 110. That is to say, the telescopic support structure 200 is vertically upward and inclined to the falling window 110 by a certain angle, which may be 30 to 60 degrees, so that the support in the XYZ three dimensional directions of the power assembly 500 can be realized, and the limit support can be stabilized in the horizontal plane to limit the lateral deviation.

It should be noted that, in cooperation with the retractable support structure 200, the first support height can be maintained when the power assembly 500 is supported by magnetic levitation, and the magnetic levitation support height is superimposed to maintain the first support height.

When collision impact occurs, the electromagnet 300 is rapidly powered off, the electromagnetic field is eliminated, and the power assembly 500 falls under the action of gravity; at the same time, the telescoping support structure 200 retracts, leaving room for the powertrain 500. The retractable support structure 200 is disposed on the base 100 in an inclined supporting manner, faces the inner side of the falling window 110, and supports the power assembly 500 in an inclined upward direction, so that the retractable support structure 200 can be retracted to achieve avoidance.

It should be noted that the extension amount of the retractable supporting structure 200 can be directly extended under the condition that the electromagnet 300 is not electrified, so as to compensate the point magnetic suspension supporting height, and the point magnetic suspension supporting height is directly supported by the permanent magnet in a contact manner, so as to meet the requirements of maintenance and supporting height under the assembly working condition.

For convenience of processing, forming and assembling, the falling window 110 is configured as a quasi-rectangular window, and the four magnetic suspension suspensions are correspondingly arranged in four corner regions of the quasi-rectangular window to correspondingly support the power assembly 500, so that a simple and stable support structure is realized.

The permanent magnets 400 can be fixed at four corners of the bottom end of the power assembly 500, and for convenience of installation, four inclined surfaces 510 can be formed at the four corners of the bottom end of the power assembly 500 to match with the angles of the inclined supports, so that the permanent magnets 400 can be opposite to the electromagnets 300, and the reliability of magnetic suspension support can be ensured.

Generally, the base 100 can be directly used as a subframe with the drop window 110 formed therein, or the base 100 can be molded to the subframe.

And the electromagnet is fixed through the telescopic supporting structure, so that the supporting height can be adjusted, and the power assembly can still be fixed in a physical contact supporting mode under the condition of no electrification. On the other hand, when the vehicle is impacted, the power can be quickly cut off to close the magnetic field, and the supporting structure is contracted, so that the power assembly can freely fall down to pass through the auxiliary frame and fall under the vehicle, and the situation that the power assembly moves backwards and is immersed in a cabin is avoided, and the safety of personnel and equipment in the vehicle is threatened; and more buffer spaces are provided for safe collision, and the safety is improved.
