Background technology
Unmanned plane because its it is widely used, easy to use the features such as, gradually popularized in industry-by-industry more and more.Utilize nothing
Man-machine carrying camera realizes that the transmission of remote high-definition image is that unmanned plane is earliest, one of most important application field.Unmanned plane
Aerial photography function is realized by carrying clouds terrace system, and clouds terrace system need to be installed on unmanned plane body by vibration absorber.In addition,
The core devices IMU (Inertial Measurement Unit) that unmanned plane flies control is also required to filter fuselage shaking by vibration absorber, steady to realize
Fixed winged control.Therefore, effective vibration absorber is most important to unmanned plane safe flight, high quality imaging.
The vibration absorber of existing unmanned plane antivibration area is all single-stage vibration absorber, and the method for its vibration isolation optimizing is：
By adjusting the hardness of shock absorber part material, contrast test is carried out, realizes the preferred of shock absorber part material hardness.This method is only
The optimization design of vibration absorber can be realized in limited range, exist can the small significant drawback in design space, tend not to reach
Desired purpose of design, when shock absorber part material hardness is relatively low, easily occurs moderate finite deformation, influences to use；Work as damper
When part material hardness is higher, and it is difficult to realize preferable effectiveness in vibration suppression.When configuration design is unreasonable, vibration absorber itself is intrinsic
Frequency there is a possibility that to couple with vibration source input stimulus frequency, due to can design space it is limited, tend not to realize effective
Wrong frequency designs, and causes vibration absorber to resonate, significantly affects flight reappearance and image quality.
The content of the invention
According to above the deficiencies in the prior art, the technical problems to be solved by the invention are：A kind of multi-level damping dress is provided
Put, can be greatly improved the designability of vibration absorber itself frequency point, frequency point can scope of design it is wide, can join by adjusting design
Number, effectively realizes and is designed with the wrong frequency of vibration source input stimulus frequency.
A kind of multi-level damping device is characterized in that：Including multiple grades of damper units and connecting board structure, the vibration damping list
Member is connected by the connecting plate, and the upper end of the multi-level damping device is connected with unmanned plane carrier, the multi-level damping device
Lower end be connected with payload.
Further, the damper unit quantity includes being more than or equal to 2.
In one embodiment, the shock absorber part is buffering ball form.
Further, the material of the shock absorber part is damping buffering material, can be rubber or foam.
In one embodiment, the shock absorber part material is rubber.
Further, the quantity of the shock absorber part includes being more than or equal to 2.
In one embodiment, the quantity for stating shock absorber part is 4.
Further, the shock absorber part is integrated shaping using silica gel, rubber flexible material.
The beneficial effects of the invention are as follows：
A kind of multi-level damping device is provided, the designability of vibration absorber itself frequency point can be greatly improved, frequency point can be set
It is wide to count scope, can effectively realize and designed with the wrong frequency of vibration source input stimulus frequency by adjusting design parameter.
