Hole 204, reduce the radial load that shock-damping structure 100 is subject to when mounted, avoid shock-damping structure 100 from being damaged when mounted.
The first interconnected opening 205 and mounting hole 204 form fixing hole 203.In the present embodiment, four fixing holes
203 are arranged on the edge of fixed support 201, and the line of four fixing holes 203 is in isosceles trapezoid shape.
It is understood that fixed support 201 and four shock-damping structures 100 with this arrangement mode of fixing hole 203
Coordinate, and for being connected with the first installing plate 230 and the second installing plate 240, its Stability Analysis of Structures, can effectively prevent the first peace
The bias of 230 and second installing plate of loading board 240 is rocked.
As long as it can realize that two share the dampening assembly 250 by damping part.In other preferred embodiments, shock-damping structure
100 quantity and the structure of fixed support 201 can have different changes.For example, the quantity of shock-damping structure 100 is one, accordingly
Ground, sets a fixing hole 203 on fixed support 201, and with the fixation clamping matching of the shock-damping structure 100.Or damping knot
The quantity of structure 100 is three, correspondingly, three fixing holes 203 is set on fixed support 201, and three fixing holes 203 are in isosceles
Triangle is separately positioned on the destination edge of fixed support 201, respectively with the fixation clamping matching of three shock-damping structures 100.Certainly,
The quantity of shock-damping structure 100 can also be it is multiple, on fixed support 201 set respective numbers fixing hole 203, for it is multiple
The fixation clamping matching of shock-damping structure 100.To ensure the stability of the structure of dampening assembly 250, multiple fixed screens can be made uniform
It is distributed in using the center of fixed support 201 as on the circumference in the center of circle.
Certainly, in other preferred embodiments, the structure of fixing hole 203 can also have different changes.For example, fixed support
Neck is offered on 201, neck is used for the fixation screens for housing shock-damping structure 100, also, the periphery of neck is provided with buckle
Part, fastener are used to fixed screens being placed in neck rear enclosed neck notch, and clamping shock-damping structure 100.
Preferably, in the present embodiment, mounting bracket 202 has mounting groove 206, and the opening direction of mounting groove 206 is away from solid
Fixed rack 201, mounting groove 206 are used to be connected with aircraft body.
It is understood that support 252 is mainly used in fixing shock-damping structure 100, and it is connected with aircraft body.At other
In preferred embodiment, as long as the connection with shock-damping structure 100 and aircraft body can be realized, the structure of support 252 can have not
With change.Such as support 252 only includes fixed support 201, fixed support 201 and aircraft body clamping etc..
Continue referring to Fig. 3, it is preferable that in the present embodiment, the shape of the first installing plate 230 and the second installing plate 240 is big
It is small identical with the shape size of fixed support 201, and be respectively arranged with and the structure identical of the fixing hole of fixed support 201 203
Four the first fixing holes 232 and four the second fixing holes 242.Four the first fixing holes 232 be used for respectively with four shock-damping structures
100 the first installation clamping matching, four the second fixing holes 242 are used for the second installation card with four shock-damping structures 100 respectively
Position coordinates.
During the aircraft installation that the present embodiment provides, the fixation screens of four shock-damping structures 100 is respectively clamped into four fixations
Hole 203, so as to realize the connection with aircraft body by support 252.Four first installation screens are respectively clamped into four the
One fixing hole 232, so as to secure the first installing plate 230 for being provided with IMU210.Four second installation screens are respectively clamped into four
Individual second fixing hole 242, so as to secure the second installing plate 240 being connected with head 220.And then form two layers of damping up and down
Structure, cushioning effect is played to IMU210 and head 220 respectively.
Due to the shock-damping structure 100 provided using first embodiment, the dampening assembly 250 can realize two by damping part
The dampening assembly 250 is shared, reduces installation time and assembly space occupancy, and reduce cost.
It is understood that in other preferred embodiments, the first installation screens can be used for fixing other first by damping
Part, the second installation screens can be used for fixing other second by damping part, and be not limited to the first peace for installing IMU210
Loading board 230 and for connecting the second installing plate 240 of head 220.
And, it is understood that in process of production, the structure of the first installing plate 230 and the second installing plate 240 can root
The adjustment and change of adaptability are made according to the quantity of shock-damping structure 100 and the structure of support 252.
Due to head 220, not only weight is big compared with IMU210 weight, it is also desirable to more reduce high-frequency vibration, it is therefore, excellent
Selection of land, in the present embodiment, the wall thickness of the first shock-absorbing ball 120 is more than the wall thickness of the second shock-absorbing ball 130, and the first shock-absorbing ball 120
Diameter is less than the diameter of the second shock-absorbing ball 130.That is, the thickness of the second shock-absorbing ball 130 is smaller, is relatively large in diameter.So set
The purpose put is that head 220 is relative to IMU210, and weight is bigger, the stability of requirement is higher, the thickness of the second shock-absorbing ball 130
Degree is smaller can to make head 220 be better protected from high-frequency vibration, and being relatively large in diameter for the second shock-absorbing ball 130 can make the edge of head 220
Second shock-absorbing ball, 130 diametric stability is higher, can preferably prevent head 220 along the diametric(al) of the second shock-absorbing ball 130
Rock.
It is understood that due to using the present embodiment provide dampening assembly 250, the present embodiment provide aircraft its
IMU210 and head 220 can share the dampening assembly 250, effectively reduce the quantity, installation time and dress of shock mitigation system
With space occupancy rate, and reduce cost.
