Description

Technical Field

[0001] This invention relates to the field of drone technology, and in particular to a drone battery insulation device. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. Because the working environment of UAVs is relatively complex, they sometimes need to carry out flight operations in low temperature or even extremely cold conditions. The battery of the UAV may experience problems such as power loss due to temperature, so battery insulation is required.

[0003] A search revealed Chinese patent CN220155661U, which discloses a drone battery insulation device. The device includes a shell with a groove at the front end and a handle at the front end. Anti-slip ribs are fixedly connected to both sides of the shell, a cooling fan is fixedly connected to the bottom of the shell, a raised edge is fixedly connected to the inside of the shell, a top cover is fixedly connected to the top of the shell, an insulation layer is fixedly connected to the inside of the shell, a heat-conducting layer is fixedly connected to the inside of the insulation layer, and heating modules are fixedly connected to both sides of the heat-conducting layer.

[0004] However, the above invention has the following shortcomings: During drone flight, the temperature of the battery varies significantly depending on the direction of the airflow due to the interaction between the airflow and the fuselage. The windward side is directly impacted by the high-speed airflow, resulting in intense heat dissipation and a significantly lower temperature than the leeward side. This uneven temperature distribution severely affects battery performance and lifespan. Existing insulation technologies mostly employ uniform heating or static insulation, which cannot dynamically adjust the insulation strategy according to the flight direction. Especially under high-speed, headwind, or crosswind flight conditions, the problem of localized overcooling of the battery is particularly prominent, leading to decreased battery discharge efficiency, shortened flight time, and in severe cases, even affecting flight safety. Summary of the Invention

[0005] The purpose of this invention is to provide a battery insulation device for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.

A return spring is provided between the movable frame and the mounting plate.

[0008] Preferably, a detection mechanism is provided below the battery compartment. The detection mechanism includes a detection chamber, which is fixedly installed on the bottom wall of the battery compartment. Multiple air inlets are provided on the side wall of the detection chamber, and the air inlets penetrate through the side wall of the detection chamber to connect to the interior of the detection chamber. An air inlet pipe is movably installed on the side wall of the detection chamber at the position corresponding to the air inlet.

[0009] Preferably, the interior of the air inlet pipe gradually narrows towards the testing chamber. Multiple partitions are fixedly installed inside the testing chamber, dividing the interior of the testing chamber into multiple parts. An air outlet is provided at the bottom of the testing chamber corresponding to the position of the partition. A movable plate is provided inside the air inlet. A crossbar is fixedly installed on the partition corresponding to the position of the movable plate, and the crossbar passes through the side wall of the movable plate.

[0010] Preferably, a second return spring is sleeved on the crossbar, the second return spring is movably connected to the movable plate, a pressure rod is installed on the movable plate, a pressure sensor is fixedly installed on the side wall of the partition corresponding to the position of the pressure rod, one end of the pressure rod is connected to the input end of the pressure sensor, and a sealing plate is movably installed inside the partition through a torsion spring shaft.

[0011] Preferably, a drive motor is fixedly installed inside the detection chamber. The output end of the drive motor passes through the bottom wall of the battery compartment and is located inside the battery compartment. The drive motor and the pressure sensor are electrically connected through a controller. A mounting base is installed on the output end of the drive motor. An electric telescopic rod is embedded in the mounting base. A push plate is installed on the output end of the electric telescopic rod. The position of the push plate corresponds to that of the movable frame.

[0012] Preferably, the electric telescopic rod is equipped with a mounting base 2, the electric telescopic rod 2 is fixedly mounted on the mounting base 2, a fixing head is mounted on the output end of the electric telescopic rod 2, and a fixing seat is fixedly mounted on the bottom of the base plate corresponding to the position of the electric telescopic rod 1.

[0013] Preferably, the fixed base is provided with a fixing groove corresponding to the position of different movable frames, and the bottom of the fixing groove gradually increases from top to bottom.

[0014] Preferably, a vibrating rod is fixedly installed at the top of the air inlet pipe, the vibrating rod extends upward through the bottom wall of the battery compartment and is located inside the battery compartment, a vibrating plate is fixedly installed at the top of the vibrating rod, and vibrating blocks are fixedly installed at equal intervals at the top of the vibrating plate.

[0015] Preferably, the vibrating plate and vibrating block correspond to the movable frame, a return spring is sleeved on the vibrating rod, and multiple vibrating blocks are provided, with intervals between the multiple vibrating blocks.

[0016] This invention provides an improved drone battery insulation device, which has the following improvements and advantages compared to the prior art: Firstly, in this invention, when the drone is flying, the airflow generated by the flight direction enters the corresponding air inlet duct. Under pressure, the movable plate moves on the crossbar. When the movable plate moves into the detection chamber, the airflow can enter the detection chamber. At the same time, the movable plate compresses the second reset spring, which in turn compresses the pressure sensor when the movable plate moves. The faster the drone flies, the faster the airflow, and the greater the distance the movable plate moves, the greater the pressure on the pressure sensor. After the pressure sensor is compressed, the drive motor is activated, which drives the mounting base to rotate to the corresponding direction. Subsequently, the electric telescopic rod is activated, which drives the push plate towards the corresponding movable frame. As the drone moves, the push plate presses against the movable frame, causing it to move towards the second drive shaft. Since the movable frame and the second drive shaft are connected by a thread, the movement of the movable frame causes the second drive shaft to rotate. When the second drive shaft rotates, it drives the second drive gear to rotate, which in turn drives the first drive gear to rotate via a drive belt. The first drive gear then drives the first drive shaft to rotate. The first drive shaft is threadedly connected to the heating plate, which is then driven by the first drive shaft to move inside the battery compartment. This changes the distance between the heating plate and the battery, thus achieving the effect of automatically adjusting the distance between the heating plate and the battery according to the direction of the drone's flight. This allows for automatic adjustment of the battery's heat preservation effect based on temperature, ensuring that the battery is heated evenly when flying in different directions.

[0017] Secondly, in this invention, after the drive motor drives the first electric telescopic rod to rotate, the second electric telescopic rod can be started. The second electric telescopic rod will drive the fixed head to move upward. At this time, the fixed head corresponds to the position of a certain fixed groove, and the fixed head will move into the inside of the fixed groove, thereby limiting the first electric telescopic rod and preventing the first electric telescopic rod from shaking when it is started, which would prevent the first electric telescopic rod from driving the push plate to contact the movable frame.

[0018] Thirdly, in this invention, when the movable frame moves, it will compress the vibrating block. After being compressed, the vibrating block will drive the vibrating plate to move downward, which in turn will drive the air inlet pipe to move on the detection chamber via the vibrating rod. At the same time, a return spring three is sleeved on the vibrating rod, and multiple vibrating blocks are provided. When the vibrating plate moves downward, it will compress the return spring three. There are gaps between the multiple vibrating blocks. When the movable frame moves to the gap position, the return spring three will release its elastic force, which will drive the air inlet pipe to return to its original position. Thus, the air inlet pipe will be vibrated when the movable frame moves. The vibration can eliminate the ice crystals generated inside the air inlet pipe at low temperatures, avoiding the situation where the ice crystals generated inside the air inlet pipe at low temperatures affect the airflow detection.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides an improved drone battery insulation device. The technical solution of this invention is as follows: like Figures 1 to 2 As shown, this embodiment of the invention provides a drone battery insulation device, including a battery compartment 1, a top cover 2, and a battery 4 located inside the battery compartment 1. The battery compartment 1 has a hollow structure and is installed under the drone by external clips. The top cover 2 is movably installed on top of the battery compartment 1, sealing the interior of the battery compartment 1. A base plate 3 is fixedly installed at the bottom of the interior of the battery compartment 1. The base plate 3 is a rectangular plate that divides the interior of the battery compartment 1 into two parts. The battery 4 is movably installed on the base plate 3. Multiple heating plates 5 are provided on the base plate 3. The heating plates 5 are rectangular plates with heating wires. The heating plates 5 can dissipate heat. When flying at high altitudes, the temperature inside the battery compartment 1 is low. In order to ensure the battery 4's endurance, the heating plates 5 can be used to insulate the battery 4, so that the battery 4's endurance will not decrease due to low temperature.

[0024] like Figure 2 and Figure 3As shown, a transmission mechanism is installed inside the battery compartment 1. This mechanism includes a drive shaft 6, which is a threaded cylindrical structure. The number of drive shafts 6 is the same as the number of heating plates 5. Drive shafts 6 are rotatably mounted on the inner wall of the battery compartment 1 and threadedly connect to the side wall of the heating plate 5. This allows the heating plate 5 to move horizontally along the drive shaft 6 when it rotates, changing the distance between the heating plate 5 and the battery 4, thus altering the amount of heat dissipated from the battery 4. A transmission gear 7 is fixedly mounted on the end of drive shaft 6 away from the heating plate 5. The transmission mechanism also includes a second drive shaft 8, which is also a threaded cylindrical structure. The second drive shaft 8 is movably mounted inside the battery compartment 1 and located below the base plate 3. One end of the second drive shaft 8 is fixedly positioned corresponding to the position of the transmission gear 7. A transmission gear 29 is fixedly installed. A transmission belt 10 is movably connected between transmission gear 17 and transmission gear 29. The transmission belt 10 meshes with transmission gear 17 and transmission gear 29 respectively. Since the direction of the drone during flight is often inconsistent, the side of battery 4 facing the flight direction is impacted by the airflow and its temperature will be lower than the other sides. If the distance between heating plate 5 and battery 4 is kept consistent, battery 4 will be heated unevenly. As a result, when transmission shaft 28 rotates, transmission shaft 28 can drive transmission gear 29 to rotate. Transmission gear 29 can then drive transmission gear 17 to rotate via transmission belt 10. Transmission gear 17 can then drive transmission shaft 6 to rotate. Transmission shaft 6 is threadedly connected to heating plate 5. The heating plate 5 will be driven by transmission shaft 6 to move inside battery compartment 1, thereby changing the distance between heating plate 5 and battery 4.

[0025] like Figure 2 and Figure 4As shown, a drive mechanism is installed inside the battery compartment 1. The drive mechanism includes a movable frame 11, which is a hollow rectangular structure. The movable frame 11 is located inside the battery compartment 1 at a position corresponding to the second drive shaft 8. The second drive shaft 8 passes through one side wall of the movable frame 11, and the second drive shaft 8 and the movable frame 11 are connected by threads. A mounting plate 12 is fixedly installed on the bottom of the base plate 3 at a position corresponding to the movable frame 11. The mounting plate 12 is a rectangular plate, and the movable frame 11 passes through the side wall of the mounting plate 12. The movable frame 11 is movably installed inside the battery compartment 1 via the mounting plate 12. The movable frame 11 and the mounting plate... A return spring 13 is provided between the movable frame 11 and the mounting plate 12. When the movable frame 11 moves toward the drive shaft 8, the drive shaft 8 will rotate due to the threaded connection between the movable frame 11 and the drive shaft 8. The drive shaft 8 can drive the heating plate 5 to move through the transmission mechanism. When the movable frame 11 moves, it will press the return spring 13 against the mounting plate 12. When the movable frame 11 stops moving, the return spring 13 will release its elastic force, thereby driving the movable frame 11 to reset. At this time, the heating plate 5 will also reset.

[0026] like Figure 1 , Figure 2 , Figure 5 as well as Figure 6As shown, a detection mechanism is installed below the battery compartment 1. The detection mechanism includes a detection chamber 14, which is a hollow cylindrical structure. The detection chamber 14 is fixedly installed on the bottom wall of the battery compartment 1. Multiple air inlets 15 are opened on the side wall of the detection chamber 14. The air inlets 15 are circular holes that penetrate the side wall of the detection chamber 14 and connect to the interior of the detection chamber 14. An air inlet pipe 16 is movably installed on the side wall of the detection chamber 14 corresponding to the position of the air inlet 15. The air inlet pipe 16 is a hollow structure, and the interior of the air inlet pipe 16 gradually narrows towards the detection chamber 14. When the drone is flying, the external airflow is guided by the air inlet pipe 16 and then enters the detection chamber through the air inlets 15. Inside the detection chamber 14, multiple partitions 19 are fixedly installed. Each partition 19 is a hollow rectangular structure, dividing the interior of the detection chamber 14 into several sections. An air outlet 17 is provided at the bottom of the detection chamber 14 corresponding to the position of the partition 19. The air outlet 17 is a rectangular slot, through which the airflow entering the detection chamber 14 is finally discharged. A movable plate 18 is installed inside the air inlet 15. The movable plate 18 is a circular plate adapted to the air inlet 15. A horizontal bar 20 is fixedly installed on the partition 19 corresponding to the position of the movable plate 18. The horizontal bar 20 is a cylindrical structure and penetrates the side wall of the movable plate 18. A second return spring 21 is fitted onto the 0, and the second return spring 21 is movably connected to the movable plate 18. Through the arrangement of the movable plate 18, the crossbar 20, and the second return spring 21, when the UAV is flying, the airflow generated by the flight will enter the interior of the corresponding air inlet 16 according to the flight direction. Under the action of pressure, the movable plate 18 will move on the crossbar 20. When the movable plate 18 moves into the interior of the detection chamber 14, the airflow can enter the interior of the detection chamber 14. At the same time, the movable plate 18 squeezes the second return spring 21. A pressure rod 22 is installed on the movable plate 18. The pressure rod 22 is a cylindrical rod. A pressure sensor is fixedly installed on the side wall of the partition 19 at the position corresponding to the pressure rod 22. Device 23, one end of pressure rod 22 is connected to the input end of pressure sensor 23, so that when movable plate 18 moves, pressure rod 22 will squeeze pressure sensor 23. The faster the drone flies, the faster the airflow speed, and the greater the distance the movable plate 18 moves, the greater the pressure on pressure sensor 23. Inside partition 19, sealing plate 24 is movably installed through torsion spring shaft. Sealing plate 24 is a rectangular plate and is unidirectionally set inside partition 19, so that the airflow inside detection chamber 14 can squeeze sealing plate 24 out of the detection chamber 14, while external airflow cannot enter the detection chamber 14 through partition 19.

[0027] like Figure 2 , Figure 7 as well as Figure 8As shown, a drive motor 25 is fixedly installed inside the detection chamber 14. The output end of the drive motor 25 passes through the bottom wall of the battery compartment 1 and is located inside the battery compartment 1. The drive motor 25 is electrically connected to the pressure sensor 23 through a controller. A mounting base 26 is installed on the output end of the drive motor 25, and an electric telescopic rod 27 is embedded in the mounting base 26. A push plate 28 is installed on the output end of the electric telescopic rod 27, and the push plate 28 corresponds to the position of the movable frame 11. Since the pressure sensor 23 and the drive motor 25 are electrically connected, when the UAV flies to one side, the airflow will enter the detection chamber 14 in the corresponding direction, and then drive the pressure rod 22 through the air inlet pipe 16 to squeeze the pressure sensor 23. After the pressure sensor 23 is squeezed, it will activate the drive motor 25. The drive motor 25 drives the mounting base 26 to rotate in the corresponding direction. Then, the electric telescopic rod 27 is activated, which drives the push plate 28 to move in the direction of the corresponding movable frame 11. The push plate 28 presses against the movable frame 11, and the movable frame 11 moves towards the drive shaft 8. Since the movable frame 11 and the drive shaft 8 are connected by threads, the movement of the movable frame 11 will cause the drive shaft 8 to rotate. The drive shaft 8 can drive the heating plate 5 to move through the transmission mechanism, thereby achieving the effect of automatically adjusting the distance between the heating plate 5 and the battery 4 according to the direction of the drone's flight. This allows for automatic adjustment of the heat preservation effect on the battery 4 according to the temperature, ensuring that the battery 4 is heated evenly when flying in different directions.

[0028] An electric telescopic rod 27 is mounted on a mounting base 29, and an electric telescopic rod 30 is fixedly mounted on the mounting base 29. A fixed head 31 is mounted on the output end of the electric telescopic rod 30. A fixed seat 32 is fixedly mounted on the bottom of the base plate 3 at the position corresponding to the electric telescopic rod 27. The fixed seat 32 is a circular plate, and a fixed groove 33 is opened on the fixed seat 32 at the position corresponding to different movable frames 11. When the drive motor 25 drives the electric telescopic rod 27 to rotate, the electric telescopic rod 30 can be started. The electric telescopic rod 30 will drive the fixed head 31 to move upward. At this time, the fixed head 31 is aligned with the position of a certain fixed groove 33, and the fixed head 31 will move into the inside of the fixed groove 33. This can limit the electric telescopic rod 27 and prevent the electric telescopic rod 27 from shaking when it is started, which would prevent the electric telescopic rod 27 from driving the push plate 28 to contact the movable frame 11. At the same time, the bottom of the fixed groove 33 gradually increases from top to bottom, which makes it easier for the fixed head 31 to move into the inside of the fixed groove 33.

[0029] like Figure 6As shown, a vibrating rod 34 is fixedly installed on the top of the air inlet pipe 16. The vibrating rod 34 has a cylindrical structure and extends upward through the bottom wall of the battery compartment 1, located inside the battery compartment 1. A vibrating plate 35 is fixedly installed on the top of the vibrating rod 34. The vibrating plate 35 has a rectangular structure, and multiple vibrating blocks 36 are fixedly installed at equal intervals on the top of the vibrating plate 35. The vibrating blocks 36 are triangular blocks. The vibrating plate 35 and the vibrating blocks 36 correspond to the movable frame 11, so that when the movable frame 11 moves, it will squeeze the vibrating blocks 36. After the vibrating blocks 36 are squeezed, they will drive the vibrating plate 35 to move downward, which in turn will drive the vibrating rod 34 to move the vibrating plate 35 downward. The air inlet pipe 16 moves on the detection chamber 14. At the same time, a reset spring 37 is sleeved on the vibrating rod 34, and multiple vibrating blocks 36 are provided. When the vibrating plate 35 moves downward, it will squeeze the reset spring 37. There are gaps between the multiple vibrating blocks 36. When the movable frame 11 moves to the gap position, the reset spring 37 will release its elastic force, thereby driving the air inlet pipe 16 to reset upward. Thus, the air inlet pipe 16 will be vibrated when the movable frame 11 moves. The vibration can eliminate the ice crystals generated inside the air inlet pipe 16 at low temperatures, and avoid the situation where the ice crystals generated inside the air inlet pipe 16 at low temperatures affect the airflow detection.

[0030] Specific implementation steps: When the drone is flying, the airflow generated by the flight direction will enter the corresponding air inlet duct 16. Under pressure, the movable plate 18 will move on the crossbar 20. When the movable plate 18 moves into the detection chamber 14, the airflow can enter the detection chamber 14. At the same time, the movable plate 18 squeezes the second reset spring 21, so that when the movable plate 18 moves, the pressure rod 22 will squeeze the pressure sensor 23. The faster the drone flies, the faster the airflow, and the greater the distance the movable plate 18 moves. The greater the pressure on the pressure sensor 23, the more pressure the pressure sensor 23 will be. After the pressure sensor 23 is squeezed, the drive motor 25 will be activated. The drive motor 25 will drive the mounting base 26 to rotate to the corresponding direction. Then the electric telescopic rod 27 will be activated, which will drive the push plate 28 to move in the corresponding direction. As the frame 11 moves, the push plate 28 presses against the movable frame 11, causing the movable frame 11 to move towards the drive shaft 2 8. Since the movable frame 11 and the drive shaft 2 8 are connected by threads, the movement of the movable frame 11 causes the drive shaft 2 8 to rotate. When the drive shaft 2 8 rotates, it drives the drive gear 2 9 to rotate. The drive gear 2 9 can then drive the drive gear 1 7 to rotate via the drive belt 10. The drive gear 1 7 can then drive the drive shaft 1 6 to rotate. The drive shaft 1 6 is connected to the heating plate 5 by threads, and the heating plate 5 is driven by the drive shaft 1 6 to move inside the battery compartment 1, thereby changing the distance between the heating plate 5 and the battery 4. This achieves the effect of automatically adjusting the distance between the heating plate 5 and the battery 4 according to the direction of the drone's flight, thus automatically adjusting the heat preservation effect on the battery 4 according to the temperature, ensuring that the battery 4 is heated evenly when flying in different directions.
