Description

Technical Field

[0001] This utility model belongs to the field of optoelectronic pod technology, specifically relating to a shock absorption device for an optoelectronic pod of an aviation unmanned aerial vehicle. Background Technology

[0002] Electro-optical pods acquire images of designated targets, enabling functions such as reconnaissance, tracking, navigation, and surveillance. They are widely used in both military and civilian fields. Vibration of the pod's onboard equipment can cause out-of-focus and blurred images, a significant factor affecting the pod's imaging quality. Therefore, effective vibration reduction measures must be implemented to suppress the transmission of aircraft vibration to the pod and improve its anti-interference capabilities to obtain clear images.

[0003] In existing technologies, rubber vibration dampers have a low elastic modulus, enabling them to produce large elastic deformations. When subjected to external forces, they can better absorb vibrations and reduce the impact on equipment, making them widely used in various engineering fields. However, in the past, when rubber vibration dampers were connected to carrier aircraft and optoelectronic pods, they were usually subjected to tensile loads during operation, which easily led to rubber stress relaxation. Furthermore, the center of gravity of the optoelectronic pod was difficult to adjust, resulting in poor vibration damping performance. Utility Model Content

[0004] The purpose of this utility model is to provide a shock absorption device for an optoelectronic pod of an aviation unmanned aerial vehicle (UAV), overcoming the aforementioned technical problems existing in the prior art.

[0005] Therefore, the technical solution provided by this utility model is as follows:

[0006] A vibration damping device for an aerial unmanned aerial vehicle (UAV) optoelectronic pod includes a carrier connecting plate, a second damping plate, and a first damping plate arranged sequentially from top to bottom. The carrier connecting plate and the first damping plate are connected by a support and fixing device. A damping ball is provided between the second damping plate and the first damping plate and is respectively connected to the upper and lower ends of the damping ball. The carrier connecting plate is connected to the aerial UAV, and the second damping plate is connected to the optoelectronic pod.

[0007] The first shock absorber plate is annular, and multiple first connecting holes and limiting holes are evenly distributed on the annular plate, with the first connecting holes and limiting holes arranged at intervals.

[0008] The second damping plate has a through hole 1 in the center. The second damping plate has multiple second connecting holes and limiting holes 2 evenly distributed. The second connecting holes are located close to the through hole 1. The limiting holes 1 and 2 correspond one to one. The second damping plate and the photoelectric pod are connected by pod connecting screws passing through the second connecting holes.

[0009] The carrier connecting plate has a through hole 2 in the center. The carrier connecting plate has multiple third connecting holes and fourth connecting holes evenly distributed. The first connecting holes and the third connecting holes correspond one-to-one. The carrier connecting plate and the UAV are connected by carrier connecting bolts passing through the fourth connecting holes.

[0010] The support and fixing device includes a sleeve and a fixing bolt. The sleeve is located between the carrier connecting plate and the first shock absorber plate. The fixing bolt passes through the first connecting hole and the third connecting hole in sequence and then connects the carrier connecting plate and the first shock absorber plate.

[0011] The carrier connecting plate, the second damping plate, and the first damping plate are all made of carbon fiber.

[0012] The shock-absorbing ball is a rubber product.

[0013] The beneficial effects of this utility model are:

[0014] The shock absorption device for the optoelectronic pod of this utility model improves its performance and avoids rubber stress relaxation by setting a shock-absorbing ball between the first shock-absorbing plate and the second shock-absorbing plate.

[0015] This optoelectronic pod vibration damping device uses a support and fixing device between the carrier connecting plate and the first damping plate. This supports the damping device and horizontally limits the second damping plate, preventing excessive horizontal displacement of the damping ball and avoiding internal damage or breakage. Simultaneously, the center of gravity of the combined optoelectronic pod and damping device structure can be adjusted by changing the sleeve length, improving its vibration damping performance and enhancing the flight stability of the unmanned aerial vehicle (UAV).

Figure 1 As shown, the system includes, from top to bottom, a carrier connecting plate 1, a second damping plate 2, and a first damping plate 3. The carrier connecting plate 1 and the first damping plate 3 are connected by a support and fixing device. A damping ball 5 is provided between the second damping plate 2 and the first damping plate 3, and is connected to the upper and lower ends of the damping ball 5 respectively. The carrier connecting plate 1 is connected to the unmanned aerial vehicle (UAV), and the second damping plate 2 is connected to the electro-optical pod 9. Figure 2 As shown.

[0027] The shock absorption device for the optoelectronic pod of the unmanned aerial vehicle provided in this embodiment improves its performance and avoids stress relaxation by setting a shock-absorbing ball 5 between the first shock-absorbing plate 3 and the second shock-absorbing plate 2, so that the shock-absorbing ball 5 can bear the compressive load during operation.

[0028] Example 2

[0029] Based on Example 1, this example provides a vibration damping device for an aerial unmanned aerial vehicle (UAV) optoelectronic pod, such as... Figure 4 As shown, the first damping plate 3 is annular, and a plurality of first connecting holes 10 and limiting holes 11 are evenly distributed on the annular surface, with the first connecting holes 10 and limiting holes 11 arranged at intervals.

[0030] The first connecting hole 10 is used to connect with the carrier connecting plate 1, and the limiting hole 11 is used to connect with the shock-absorbing ball 5.

[0031] Example 3

[0032] Based on Example 2, this example provides a vibration damping device for an aerial unmanned aerial vehicle (UAV) optoelectronic pod, such as... Figure 5 As shown, the second damping plate 2 has a through hole 16 at its center. The second damping plate 2 has a plurality of second connecting holes 12 and limiting holes 13 evenly distributed on it. The second connecting holes 12 are located close to the through hole 16. The limiting holes 11 and 13 correspond one to one. The second damping plate 2 and the photoelectric pod 9 are connected by pod connecting screws 6 that pass through the second connecting holes 12.

[0033] like Figure 4 As shown, a bolt passes through the damping ball 5, and the two ends of the bolt pass through limiting hole 11 and limiting hole 13 respectively to connect the first damping plate 3 and the second damping plate 2. The bolt is located at the notch of the carrier connecting plate 1 for easy connection and disassembly.

[0034] The photoelectric pod 9 passes through the center of the first damping plate 3 from bottom to top, and is connected to the second damping plate 2 by the pod connecting screw 6.

[0035] In this embodiment, the carrier connecting plate 1, the second damping plate 2, and the first damping plate 3 are all made of carbon fiber. The damping ball 5 is made of rubber. The elasticity of the rubber generates a buffering force to achieve shock absorption.

[0036] Example 4

[0037] Based on Example 2, this example provides a vibration damping device for an aerial unmanned aerial vehicle (UAV) optoelectronic pod, such as... Figure 3 As shown, the carrier connecting plate 1 has a through hole 17 in the center, and multiple third connecting holes 14 and fourth connecting holes 15 are evenly distributed on the carrier connecting plate 1. The first connecting hole 10 and the third connecting hole 14 correspond one-to-one.

[0038] In practical applications, the shock absorption device provided by the planetary system can be used in combination with the existing optoelectronic pod 9 and unmanned aerial vehicles (UAVs) (not shown in the figure, such as fixed-wing and rotary-wing UAVs). Specifically, in this application, the carrier connecting plate 1 is used to connect to the UAV equipment. The optoelectronic pod 9 is connected to the second shock absorption plate 2 through the pod connecting screw 6. When the UAV vibrates, the vibration is transmitted sequentially along the carrier connecting plate 1, sleeve 4, first shock absorption plate 3, shock absorption ball 5 and second shock absorption plate 2. Under the action of compression elasticity, the shock absorption ball 5 causes relative displacement between the second shock absorption plate 2 and the first shock absorption plate 3, thereby achieving the shock absorption effect on the optoelectronic pod 9 and suppressing the impact of carrier vibration on the imaging quality of the optoelectronic pod 9.

The fixing bolt 8 passes through the first connecting hole 10 and the third connecting hole 14 in sequence and then connects the carrier connecting plate 1 and the first damping plate 3.

[0041] The sleeve 4 horizontally limits the second damping plate 2, suppressing occasional excessive horizontal displacement of the damping ball 5 and preventing internal damage or breakage. In practical applications, the center of gravity of the combined structure of the optoelectronic pod 9 and the damping device can be adjusted by changing the length of the sleeve 4, thereby improving the flight stability of the UAV.

[0042] In this embodiment, the sleeve 4 is made of aluminum.
