Protective device for anti-jamming emergency return-to-home control module chip of UAV

Abstract

This utility model discloses a protective device for an anti-interference emergency return-to-home control module chip of a UAV, relating to the field of UAV safety control technology. The device includes a protective component, which comprises a protective shell. This utility model transmits vibration force downwards through an outer protective plate, causing it to press downwards. The outer protective plate then drives a fixing groove and a spring to press downwards. Due to the connection between the fixing block and the spring, the spring buffers part of the vibration force. Simultaneously, the fixing block pushes a stop block downwards, further dissipating some of the vibration force due to the rubber pad. The honeycomb plate, in conjunction with the device, achieves shock absorption and protection, effectively reducing damage to the control module chip from high-frequency vibrations and drop impacts. This ensures stable operation under complex electromagnetic environments and extreme temperature conditions, meeting the operational needs of UAVs in harsh environments such as plateaus and deserts.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) safety control technology, specifically to a protective device for the UAV anti-interference emergency return-to-home control module chip. Background Technology

[0002] The anti-jamming emergency return-to-home control module for unmanned aerial vehicles (UAVs) is a key component in the field of UAV safety control technology. This module is responsible for guiding the UAV to return safely when it is subjected to electromagnetic interference or loses signal, ensuring the safety of the UAV and its payload. However, this module faces numerous challenges in complex and ever-changing operating environments.

[0003] Problems with existing technology

[0004] In existing technologies, the protection of UAV anti-interference emergency return-to-home control modules mainly relies on simple physical encapsulation, such as wrapping the module in a metal box. While this method can protect the module from physical damage to some extent, its protective effect is limited when facing high-frequency vibration, drop impact, complex electromagnetic environments, and extreme temperature conditions.

[0005] Specifically, high-frequency vibrations and drop impacts may loosen or damage the internal circuit components of the module, thus affecting its normal operation. Complex electromagnetic environments may interfere with the module's signal reception and processing capabilities, causing the return-to-home command to fail to execute accurately. Extreme temperature conditions may degrade the performance of the electronic components inside the module, or even cause malfunctions.

[0006] Therefore, existing anti-interference emergency return-to-home control module protection solutions for UAVs have significant shortcomings. To meet the operational needs of UAVs in harsh environments such as plateaus and deserts, a module protection device with higher protective performance must be developed. This device not only needs to withstand high-frequency vibrations and drop impacts, but also needs to maintain stable operation under complex electromagnetic environments and extreme temperature conditions.

[0007] In summary, this utility model proposes a protective device for an anti-interference emergency return-to-home control module chip for unmanned aerial vehicles (UAVs), aiming to solve the problems existing in the prior art, improve the protective performance of the module, and ensure the safe return of UAVs in harsh environments.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0010] A protective device for an anti-interference emergency return-to-home control module chip for a drone includes a protective component. The protective component includes a protective shell, a protective sealing plate on the top of the protective shell, a liquid cooling mechanism installed at the bottom inside the protective shell, and a control module chip installed on the surface of the liquid cooling mechanism.

The first serpentine pipe and the second serpentine pipe are located at the bottom inside the protective shell. One end of each of the first serpentine pipe and the second serpentine pipe is fixedly connected to a second connector.

[0015] A further improvement of this utility model is that a connecting pipe is fixedly connected between the two second connectors, and a first connector is fixedly connected to one end of both the first serpentine pipe and the second serpentine pipe. Coolant cools the control module chip through the first serpentine pipe and the second serpentine pipe. The two second connectors are connected in series through the connecting pipe to form a closed loop.

[0018] 1. This utility model provides a protective device for the anti-interference emergency return-to-home control module chip of a UAV. Vibration force is transmitted downward through the outer protective plate and squeezes the outer protective plate downward. The outer protective plate drives the fixing groove and spring to squeeze downward. Due to the connection between the fixing block and the spring, the spring buffers part of the vibration force. At the same time, the fixing block pushes the abutment block downward, and due to the action of the rubber pad, a portion of the vibration force is further dissipated. The honeycomb plate achieves the function of shock absorption and buffer protection, effectively reducing the damage of high-frequency vibration and drop impact to the control module chip, and meeting the operational needs of UAVs in harsh environments such as plateaus and deserts.

The coolant cools the control module chip through the first serpentine pipe and the second serpentine pipe. The two second connectors are connected in series through the connecting pipe to form a closed loop. The material is copper-nickel alloy. The first connector is connected to the transfer pipe through the connecting pipe. The interface adopts O-ring fluororubber sealing ring to control the temperature fluctuation of the module chip and ensure the stability of the flight control system. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-4 As shown, this utility model provides a protective device for an anti-interference emergency return-to-home control module chip of a UAV, including a protective component 1. The protective component 1 includes a protective shell 10, a protective sealing plate 11 on the top of the protective shell 10, a liquid cooling mechanism 2 installed at the bottom inside the protective shell 10, and a control module chip 3 installed on the surface of the liquid cooling mechanism 2. The protective shell 10 and the protective sealing plate 11 are made of the same material. The protective sealing plate 11 includes a carbon fiber frame 112, a honeycomb plate 111 fixedly connected inside the carbon fiber frame 112, and an outer protective plate 110 fixedly connected to the top of the honeycomb plate 111. The inner part of the 1 has a through hole 115, and a rubber pad 113 is fixedly connected inside the through hole 115. The inner part of the outer protective plate 110 has a limiting groove 119 and a fixing groove 1191. A stop block 114 is fixedly connected to the surface of the rubber pad 113. A fixing block 116 is fixedly connected to one end of the stop block 114. Limit blocks 117 are fixedly connected to both sides of the top of the fixing block 116. The limiting block 117 is movably connected inside the limiting groove 119. A spring 118 is fixedly connected to the top of the fixing block 116. One end of the spring 118 is fixedly connected to the inside of the fixing groove 1191.

[0028] Specifically, the vibration force is transmitted downward through the outer protective plate 110 and presses down on the outer protective plate 110. The outer protective plate 110 drives the fixing groove 1191 and the spring 118 to press downward. Due to the connection between the fixing block 116 and the spring 118, the spring 118 buffers part of the vibration force. At the same time, the fixing block 116 pushes the abutment block 114 downward. Due to the action of the rubber pad 113, a portion of the vibration force is further dissipated. The effect of shock absorption and buffering is achieved through the cooperation of the honeycomb plate 111.

[0029] Example 2

[0030] like Figure 1-4 As shown, based on Embodiment 1, the present invention provides the following technical solution: Preferably, the liquid cooling mechanism 2 includes a first serpentine pipe 20, a second serpentine pipe 21, and a liquid cooling box 26. The first serpentine pipe 20 and the second serpentine pipe 21 are disposed at the bottom inside the protective shell 10. A second connector 27 is fixedly connected to one end of the first serpentine pipe 20 and the second serpentine pipe 21. A connecting pipe 28 is fixedly connected between the two second connectors 27. A first connector 22 is fixedly connected to one end of the first serpentine pipe 20 and the second serpentine pipe 21. A connecting pipe 24 is fixedly connected to one end of the first connector 22. A transmission pipe 23 is fixedly connected to one end of the connecting pipe 24. The liquid cooling box 26 is fixedly connected to the outside of the protective shell 10. A transmission pump 25 is fixedly connected to one end of the liquid cooling box 26. A transmission pipe 23 is fixedly connected to the output end of the transmission pump 25.

[0031] Specifically, the transfer pump 25 is started, and the transfer pump 25 transfers the coolant in the liquid cooling tank 26 to the inside of the first serpentine pipe 20 and the second serpentine pipe 21. The coolant cools the control module chip 3 through the first serpentine pipe 20 and the second serpentine pipe 21. The two second connectors 27 are connected in series through the connecting pipe 28 to form a closed loop. The material is copper-nickel alloy. The first connector 22 is connected to the transfer pipe 23 through the connecting pipe 24. The interface adopts an O-ring fluororubber seal.

[0032] The working principle of the protection device for the anti-interference emergency return-to-home control module chip of this UAV will be explained in detail below.

[0033] like Figure 1-4 As shown, the vibration force is transmitted downward through the outer protective plate 110 and squeezes the outer protective plate 110 downward. The outer protective plate 110 drives the fixing groove 1191 and the spring 118 to squeeze downward. Due to the connection relationship between the fixing block 116 and the spring 118, the spring 118 buffers part of the vibration force. At the same time, the fixing block 116 pushes the abutment block 114 downward to squeeze downward. Due to the action of the rubber pad 113, a part of the vibration force is further dissipated. The effect of shock absorption and buffering is achieved through the cooperation of the honeycomb plate 111. The transfer pump 25 is started. The transfer pump 25 transfers the coolant in the liquid cooling box 26 to the inside of the first serpentine pipe 20 and the second serpentine pipe 21. The coolant cools the control module chip 3 through the first serpentine pipe 20 and the second serpentine pipe 21. The two second connectors 27 are connected in series through the connecting pipe 28 to form a closed loop. The material is copper-nickel alloy. The first connector 22 is connected to the transfer pipe 23 through the connecting pipe 24. The interface adopts an O-ring fluororubber seal.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
