Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 2, the embodiment of the utility model provides a vibration reduction connecting mechanism, which belongs to the field of unmanned aerial vehicles, and is used for connecting an unmanned aerial vehicle main body and a hanging cabin of the unmanned aerial vehicle.
In some preferred embodiments, the vibration damping connection structure includes a first support frame 100, a second support frame 200, and a vibration damping assembly 300, wherein the first support frame 100 includes a first connection plate 110, and the first connection plate 110 is provided with a guide opening 111. The second supporting frame 200 includes a second connecting plate 210 and a guiding cylinder 220, the guiding cylinder 220 movably penetrates through the guiding opening 111, and the second connecting plate 210 is mounted at one end of the guiding cylinder 220. The damper assembly 300 includes a plurality of damper members 310, one end of the damper member 310 is connected to the first connection plate 110, the other end is connected to the second connection plate 210, and the damper member 310 has elasticity.
In the above embodiment, the second support frame 200 is connected to the main body of the unmanned aerial vehicle, and the first support frame 100 is connected to the hanging cabin of the unmanned aerial vehicle. Since the guide cylinder 220 is movably inserted into the guide opening 111, the first connection plate 110 is restricted from moving relative to the second connection plate 210 only along the axial direction of the guide cylinder 220. Since the vibration absorbing member 310 has elasticity due to the first and second connection plates 110 and 210 at both ends of the vibration absorbing member 310, the vibration absorbing member 310 can attenuate the vibration amplitude transmitted from the second support frame 200 to the first support frame 100. And further improves the stability of the unmanned aerial vehicle hanging cabin.
In some preferred embodiments, a plurality of vibration damping members 310 circumferentially surround the guide opening 111. The vibration absorbing members 310 are circumferentially surrounded by the guide openings 111, so that vibration in all directions can be borne and buffered by the vibration absorbing members 310, and a better vibration absorbing effect is achieved.
Based on the above embodiments, in some preferred embodiments, the vibration reduction members 310 are distributed in a staggered manner in the radial direction of the guide opening 111. Avoiding the vibration damping members 310 being positioned on the same circumferential line, and enabling the vibration damping members 310 to be distributed in a larger range as much as possible, so that the stress of each vibration damping member 310 is uniform.
As long as the embodiments of interconnecting the vibration absorbing members 310 with the first and second connection plates 110 and 210 are possible, in some preferred embodiments, the first connection plate 110 is provided with a plurality of first mounting holes 112 corresponding to the vibration absorbing members 310 one by one, the second connection plate 210 is provided with a plurality of second mounting holes 211 corresponding to the vibration absorbing members 310 one by one, the vibration absorbing members 310 include a bearing portion 311 in the middle and two blocking portions 312 at two ends respectively, the first and second connection plates 110 and 210 clamp the bearing portion 311, and the two blocking portions 312 respectively pass through the first and second mounting holes 112 and 211 and respectively abut against one sides of the first and second connection plates 110 and 210 facing away from the bearing portion 311.
In the above embodiment, since the two blocking portions 312 respectively pass through the first mounting hole 112 and the second mounting hole 211 and respectively press the first connection plate 110 and the second connection plate 210 against the face facing away from the pressure bearing portion 311. The vibration damping member 310 may be prevented from being separated from the first mounting hole 112 or the second mounting hole 211, and thus the first connection plate 110 and the second connection plate 210 may be effectively connected to each other using the vibration damping member 310.
Based on the above embodiments, in some preferred embodiments, the damping member 310 further includes a pressing plate 320, where the pressing plate 320 is detachably mounted on the first connecting plate 110 or the second connecting plate 210, and the pressing plate 320 sandwiches the blocking portion 312 with the first connecting plate 110 or the second connecting plate 210. Clamping the blocking portion 312 with the pressing plate 320 and the first connecting plate 110 or the second connecting plate 210 can prevent the blocking portion 312 from deforming, so as to prevent the blocking portion 312 from passing through the first mounting hole 112 or the second mounting hole 211 due to deformation caused by stress.
In some preferred embodiments, vibration damping member 310 is a rubber vibration damping member 310. Rubber is a common and easily available vibration damping material, and the rubber vibration damping member 310 can be used to meet the functional requirements of the vibration damping connection structure of the present utility model. However, the preferred use of the rubber damper 310 does not mean that the damper 310 can be made of rubber only, and a material having a certain elasticity and absorbing kinetic energy can be satisfied.
It will be appreciated that if the damping member 310 is subjected to a tensile force, the connection between the damping member 310 and the first and second connection plates 110 and 210 will be correspondingly subjected to a tensile force. The load applied to the connection between the damper 310 and the first and second connection plates 110 and 210 is greatly increased, so that a more firm connection is required. In case of the pressure borne by the vibration absorbing member 310, the vibration absorbing member 310 and the first and second connection plates 110 and 210 are pressed against each other, so that the load borne by the connection between the vibration absorbing member 310 and the first and second connection plates 110 and 210 is small.
Thus, in some preferred embodiments, the first web 110 is positioned above the second web 210 such that the damper 310 may be subjected to compressive forces.
In some preferred embodiments, the first support 100 further includes a substrate 120 and a plurality of support columns 130, two ends of the plurality of support columns 130 are respectively connected to the substrate 120 and the first connection board 110, and the substrate 120 is located below the second connection board 210, and the second support 200 includes a plurality of limiting columns 230, where the limiting columns 230 press against the substrate 120 to limit the second connection board 210 from approaching the substrate 120.
It will be appreciated that during operation of the drone, the nacelle will hang under the drone and the corresponding damper 310 will be subjected to pressure. However, when the drone is parked, the drone may instead press against the pod, causing the damper 310 to be under tension. The ability of the damping member 310 to bear the tensile force is weak, and the limiting post 230 abuts against the substrate 120 at this time, so that the weight of the unmanned aerial vehicle can be borne by the limiting post 230. The damper 310 is prevented from being subjected to a tensile force.
In some preferred embodiments, a plurality of stop posts 230 surround the guide opening 111. So that each of the stopper posts 230 can be heated uniformly.
In addition, the embodiment of the utility model provides an unmanned aerial vehicle which is provided with the vibration reduction connecting structure.
The second support frame 200 is connected with the main body of the unmanned aerial vehicle, and the first support frame 100 is connected with the hanging bin of the unmanned aerial vehicle. Since the guide cylinder 220 is movably inserted into the guide opening 111, the first connection plate 110 is restricted from moving relative to the second connection plate 210 only along the axial direction of the guide cylinder 220. The vibration damping members 310 are distributed in a staggered manner in the radial direction of the guide port 111. Avoiding the vibration damping members 310 being positioned on the same circumferential line, and enabling the vibration damping members 310 to be distributed in a larger range as much as possible, so that the stress of each vibration damping member 310 is uniform. Since the two blocking portions 312 respectively pass through the first mounting hole 112 and the second mounting hole 211 and respectively press against the surfaces of the first connecting plate 110 and the second connecting plate 210 facing away from the pressure bearing portion 311. The vibration damping member 310 may be prevented from being separated from the first mounting hole 112 or the second mounting hole 211, and thus the first connection plate 110 and the second connection plate 210 may be effectively connected to each other using the vibration damping member 310. Since the damping member 310 has elasticity, the damping member 310 can attenuate the vibration amplitude transmitted from the second supporting frame 200 to the first supporting frame 100. And further improves the stability of the unmanned aerial vehicle hanging cabin.
The above-described embodiments of the present utility model do not limit the scope of the present utility model. Any of various other corresponding changes and modifications made according to the technical idea of the present utility model should be included in the scope of the claims of the present utility model.
