DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0028] A specific embodiment of the utility model is as follows Figure 1 As shown, a vibration reduction structure of an unmanned aerial vehicle-mounted electronic device is disclosed, comprising a first structural component 1, a second structural component 2, an elastic component 3 and a locking component 4; the elastic component 3 is located between the first structural component 1 and the second structural component 2, and the two ends of the elastic component 3 are respectively abutted against the first structural component 1 and the second structural component 2; the locking component 4 passes through the second structural component 2 and is fixedly connected to the first structural component 1; there is a gap between the first structural component 1 and the second structural component 2.

[0029] like Figure 2 As shown, the first structural component 1 is a shell with an opening at the top, including a bottom plate 11, a positioning portion 12, a first connecting portion 13 and a first limiting portion 14. The bottom plate 11 is provided with bilaterally symmetrical lugs, and both lugs are provided with threaded through holes for fixing the first structural component 1 on the mounting plate of the drone.

[0030] The positioning portion 12 is a first boss located at the center of the bottom plate 11 or a plurality of first bosses are symmetrically arranged around the center of the bottom plate 11. The elastic component 4 is sleeved on the outer periphery of the first boss for positioning; further, the positioning portion 12 is a positioning groove, and the elastic component 3 is placed in the positioning groove for positioning. The first connecting portion 13 is used to be fixedly connected with the locking component 4. Preferably, the first connecting portion 13 is a blind hole located at the upper part of the first boss of the positioning portion 12, and is fixedly connected with the locking component 4 by thread or snap. The first limiting portion 14 is a shell side wall perpendicular to the bottom plate 11. The elastic component 4 is located in the first limiting portion 14, and the first limiting portion 14 can limit the elastic component 4.

[0031] The second structural component 2 is a cover body matching the first structural component 1, including a cover plate 21, a guide hole 22, a device mounting portion 23 and a second limiting portion 24; the cover plate 21 is arranged parallel to the bottom plate 11, and a through guide hole 22 is provided on the cover plate 21. The guide hole 22 is a through hole located at the center of the cover plate 21 or a plurality of through holes symmetrically arranged around the center of the cover plate 21, and the number of through holes is consistent with the number of the locking component 4; the guide hole 22 is used to match the locking component 4 and guide the relative sliding between the second structural component 2 and the second structural component 2. The device mounting portion 23 is located on the cover plate 21 and is used to be fixedly connected with the airborne electronic device 5. The device mounting portion 23 is a second boss located at the center of the cover plate 21. The outer side surface of the second boss is installed with an interference fit with the mounting hole on the housing of the airborne electronic device 5, and the guide hole 22 is located at the center of the second boss. The device mounting portion 23 can also be a threaded hole, a buckle or other fixed connection structure. The second limiting portion 24 is located on a side of the cover plate 21 opposite to the base plate 11, and is a shell side wall arranged on the outer periphery of the cover plate 21. The inner wall of the second limiting portion 24 matches the outer wall of the first limiting portion 14, and the second structural component 2 and the first structural component 1 are kept coaxial for secondary guiding and limiting. The second limiting portion 24 can also protect the internal structure of the vibration reduction structure to avoid bumps, damage or dust pollution.

[0032] The elastic component 3 is sleeved on the outer periphery of the positioning portion 12, and its two ends are respectively in contact with the bottom plate 11 and the cover plate 21. Preferably, the elastic component 3 is a spring, a silicone rubber ring or other elastic component, and the axial height of the elastic component 3 is greater than the height of the first limiting portion 14 and the second limiting portion 24, so that there is a buffer gap between the ends of the first limiting portion 14 and the second limiting portion 24 and the cover plate 21 and the bottom plate 11, respectively, to ensure that there is a space between the cover plate 21 and the bottom plate 11 for axial relative movement.

[0033] The locking component 4 is a nail-shaped component, including a clamping plate 41 with a clamping function, a guide rod 42 is fixed at the center of the clamping plate 41, and a second connecting portion 421 is provided at the free end of the guide rod 42. The second connecting portion 421 can be fixed and locked with the first connecting portion 13. Preferably, the second connecting portion 421 and the first connecting portion 13 are locked by threads. One end of the guide rod 42 connected to the clamping plate 41 is a smooth rod matching the guide hole 22. When the guide rod 42 passes through the guide hole 22 and is locked with the second connecting portion 421, the second structural component 2 can slide axially between the clamping plate 41 and the first structural component 1 under the guiding action of the guide hole 22 and the guide rod 42. Preferably, the locking component 4 is a flat head bolt with a partial thread on the screw. It should be noted that when the locking component 4 is in the locked state, both ends of the elastic component 3 abut against the bottom plate 11 and the cover plate 21 respectively, and there are buffer gaps between the ends of the first limiting portion 14 and the second limiting portion 24 and the cover plate 21 and the bottom plate 11 respectively.

[0034] like Figure 3 As shown, during installation, first fix the first structural component 1 to the mounting plate of the drone with screws 6, then assemble the elastic component 3 on the positioning portion 12, and then place the second structural component 2 on the elastic component 3, and make the second limiting portion 24 and the first limiting portion 14 match, and finally fix the onboard electronic device 5 to the equipment mounting portion 23, and insert the locking component 4 into the guide hole 22 and lock it with the first connecting portion 13.

[0035] When the drone fuselage equipped with the vibration reduction structure of the utility model vibrates, the mounting plate on the fuselage drives the first structural component 1 and the locking component 4 to vibrate synchronously. Since there is a buffer gap between the first structural component 1 and the second structural component 2, under the guiding action of the guide rod 42 and the guide hole 22, the first structural component 1 slides relative to the second structural component 2 during vibration, thereby changing the distance between the cover plate 21 and the bottom plate 11, causing the elastic component 3 to produce elastic deformation due to the change in axial force at both ends, thereby absorbing the vibration energy, offsetting the force of the vibration transmitted to the second structural component 2, and reducing the influence of the vibration on the airborne electronic equipment.

[0036] The utility model has a vibration reduction effect on the electronic equipment on the unmanned aerial vehicle, improves the anti-vibration and impact resistance of the electronic equipment, and makes the electronic equipment on the unmanned aerial vehicle have higher reliability during take-off, landing and flight.
