Description

Technical Field

[0001] This invention belongs to the field of drone technology, specifically relating to a flight lifebuoy battery module. Background Technology

[0002] As a core piece of equipment for water emergency rescue, the reliability of the battery module in a flying lifebuoy directly determines its power range and mission success rate. However, existing battery modules face multiple challenges in complex aquatic environments, including inaccurate thermal management, low-temperature performance degradation, and interference from biofouling, leading to a sharp drop in battery efficiency or even sudden failure.

[0003] Specifically, firstly, battery capacity is strongly correlated with temperature: when the ambient temperature is above 45℃, the internal side reactions of lithium-ion batteries accelerate, leading to an increase in internal resistance and a decrease in usable capacity to below 70% of the nominal value; while at temperatures below 0℃, the electrolyte viscosity surges, and the discharge efficiency is less than 40% of that at room temperature. Flight lifebuoys are often exposed to intense sunlight or frigid waters, and existing passive heat dissipation / insulation designs cannot dynamically respond to temperature changes. Under high-temperature conditions, the temperature gradient of the battery pack exceeds 15℃, triggering localized thermal runaway; under low-temperature conditions, insufficient insulation causes a sudden voltage drop, triggering the system's low-voltage protection to force a shutdown.

[0004] Secondly, in marine rescue operations, dangerous creatures such as sharks and jellyfish exist in the ocean. The approach of these creatures can exacerbate the panic of those in distress and even interfere with the rescue operation. Existing flying lifebuoys usually lack the function of repelling marine life, making them unsuitable for use. Summary of the Invention

[0005] The purpose of this invention is to provide a battery module for a flying lifebuoy that can select to dissipate heat or keep the power supply warm according to the ambient temperature and the actual temperature of the power supply, so as to avoid damage to the power supply caused by drastic changes in ambient temperature, and also to avoid the safety hazards caused by excessively high battery temperature during operation. Furthermore, it can emit sound waves of a specific frequency after the device enters the water, thereby dispersing surrounding organisms and preventing the person in distress from being disturbed by aquatic organisms, which would affect the rescue.

[0006] The specific technical solution adopted by this invention is as follows:

[0007] A battery module for a flight lifebuoy includes:

[0008] The float ring has an inner cavity with a sliding connection for adding a ring;

[0009] The temperature control component includes a mounting box, a power supply is placed inside the mounting box, multiple sets of heat insulation plates are hinged to the outside of the mounting box, and a top rod is provided at the bottom of the mounting box.

[0010] The drive assembly includes a push plate, which is located below the mounting box and is fixedly connected to one end of the push rod. An arc-shaped block is fixedly connected to the lower end of the push plate, and a limit block is fixedly connected to the lower end of the inner cavity of the floating ring, with the arc-shaped block contacting and connecting to the surface of the limit block.

[0011] The electronic control component includes a sound wave generator, which is installed at the lower end of the inner cavity of the float ring.

[0012] During rescue operations, the sound wave generator emits sound waves after entering the water. When the power supply temperature is high, the arc-shaped block slides along the surface of the limit block, pushing the push plate and top rod to open the heat insulation plate. When the temperature is low, the arc-shaped block resets and drives the heat insulation plate to reset as well.

[0013] In a preferred embodiment, four sets of rotors are installed at the four corners of the outer end of the floating ring, and protective nets are provided at both the upper and lower ends of the rotors.

[0014] In a preferred embodiment, guide rails are fixedly installed at both the upper and lower ends of the inner cavity of the floating ring, and an additional ring is slidably connected to the inner cavities of the upper and lower guide rails. Spherical grooves are opened at both the upper and lower ends of the additional ring, and ball bearings are rolledly connected in the spherical grooves.

[0015] In a preferred embodiment, the upper end of the heat insulation plate is hinged to the upper end of the inner cavity of the mounting box, while the lower end of the heat insulation plate is rotatably connected to the lower end of the inner cavity of the mounting box. At the same time, the lower end of the heat insulation plate passes through the lower end of the inner cavity of the mounting box and extends out of the mounting box. The temperature control assembly also includes a drive plate, which is fixedly connected to the lower end of the portion of the heat insulation plate that extends out of the mounting box.

[0016] In a preferred embodiment, the heat insulation board is divided into three layers: an inner, middle, and outer layer, namely a heat-conducting layer, a heat insulation layer, and a protective layer. The innermost part that is in contact with the power source is the heat-conducting layer. The outer side of the heat-conducting layer is fixedly connected to the heat insulation layer, and the protective layer is fixedly connected to the outer side of the heat insulation layer.

[0017] In a preferred embodiment, the temperature control component further includes multiple sets of limiting tubes, which are uniformly and fixedly installed at the lower end of the mounting box. Multiple sets of push rods are slidably connected to the inner cavity of the limiting tubes, and the ends of the push rods away from the drive plate are fixedly connected to the middle of the push plate. The ends of the push rods near the heat insulation plate are opposite to the drive plate. A through groove is provided on the side of the limiting tube, and a protruding plate is provided on the end of the push rod facing the through groove. The protruding plate extends out of the through groove of the limiting tube, and a pull rope is fixedly connected to the side of the protruding plate facing the drive plate. The other end of the pull rope is fixedly connected to the drive plate.

[0018] In a preferred embodiment, the push rod is a T-shaped long rod, and the protruding convex plate of the push rod is slidably connected in the through groove on the side of the limiting tube.

[0019] In a preferred embodiment, the drive assembly further includes five sets of springs, which are evenly and fixedly connected to the side of the push plate facing the drive plate, and the other ends of the five sets of springs are all fixedly connected to the lower end of the mounting box.

[0020] In a preferred embodiment, the drive assembly further includes a rack, which is fixedly connected to the lower end of the inner ring of the added ring. A motor is fixedly installed at the lower end of the inner cavity of the floating ring, and a gear is fixedly connected to the output shaft of the motor. The lower end of the outer ring of the gear meshes in the tooth groove of the rack.

[0021] In a preferred embodiment, the electronic control assembly further includes four sets of control units, which are evenly distributed at the lower end of the inner cavity of the float ring. Each of the four control units is electrically connected to a power supply via cables. A temperature sensor is fixedly installed at the upper end of the mounting box, and the probe of the temperature sensor extends into the mounting box.

[0022] The technical effects achieved by this invention are as follows:

[0023] The temperature control component and drive component of the present invention can select to dissipate heat or keep the power supply warm according to the ambient temperature and the actual temperature of the power supply, so as to avoid damage to the power supply caused by drastic changes in ambient temperature, and also to avoid the safety hazards caused by excessive temperature during battery operation. Under normal conditions, if the ambient temperature is low, the heat insulation plate is attached to the surface of the mounting box and the power supply, thereby isolating the power supply from the outside temperature and keeping the power supply warm, so as to avoid the power supply capacity being damaged due to excessively low temperature. If the ambient temperature is high or the power supply temperature is too high during operation, the mounting ring is driven by the drive part of the drive component to rotate, thereby causing the arc block to slide on the surface slope of the limit block, pushing the push plate and the top rod to move and open the heat insulation plate, so that the battery can contact the outside air for heat dissipation, and avoid the safety hazards caused by excessively high temperature during power supply operation.

[0024] The electronic control component and mounting ring of the present invention can improve the smoothness and stability of power switching between heat preservation and heat dissipation modes, and avoid the switching mode from affecting the operation of the device. When switching between heat dissipation and heat preservation modes, the cable part of the electronic control component will be folded or loosened to avoid damage to the cable and affect the use of the device. At the same time, the rolling parts at the upper and lower ends of the mounting ring will roll together to reduce the friction generated when the mounting ring rotates, thereby reducing the power required for the drive component to run and improving the battery life.

[0025] The sound wave generator of the present invention can emit sound waves of a specific frequency after the device enters the water, thereby dispersing the surrounding organisms and preventing the rescuer from being disturbed by aquatic organisms, which would affect the rescue. After the floating ring falls into the water, the control part of the electronic control component controls the sound wave generator to operate and emit low-frequency sound waves, which are transmitted into the water through the lower end of the floating ring, thereby dispersing the organisms around the floating ring and preventing the organisms from approaching and startling the rescuer, which would affect the rescue work.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0043] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0044] Please see the appendix Figures 1 to 6 As shown, this embodiment provides a flight lifebuoy battery module, including:

[0045] The inner cavity of the float ring 10 is slidably connected with an additional ring 13;

[0046] Temperature control assembly 20 includes a mounting box 21, a power supply 22 is placed inside the mounting box 21, multiple sets of heat insulation plates 23 are hinged to the outside of the mounting box 21, and a top rod 26 is provided at the bottom of the mounting box 21.

[0047] The drive assembly 30 includes a push plate 31, which is located below the mounting box 21 and is fixedly connected to one end of the push rod 26. An arc-shaped block 32 is fixedly connected to the lower end of the push plate 31. A limit block 34 is fixedly connected to the lower end of the inner cavity of the floating ring 10, and the arc-shaped block 32 is in contact with the surface of the limit block 34.

[0048] The electronic control component 40 includes a sound wave generator 43, which is installed at the lower end of the inner cavity of the float ring 10.

[0049] During the rescue operation, the sound wave generator 43 emits sound waves after entering the water. When the power supply 22 is hot, the arc-shaped block 32 slides along the surface of the limiting block 34, pushing the push plate 31 and the top rod 26 to open the heat insulation plate 23. When the temperature is low, the arc-shaped block 32 resets and drives the heat insulation plate 23 to reset.

[0050] It should be noted that the side of the arc-shaped block 32 that contacts the limiting block 34 has an arc-shaped slope, while the side of the limiting block 34 that is close to the arc-shaped block 32 has a wavy arc. The distance between the lowest end and the highest end of the wavy arc is the same as the process of the top rod 26 pushing the heat insulation plate 23 to open. This is intended to make the process of the arc-shaped block 32 sliding from the lowest end to the highest end along the wavy arc of the limiting block 34 drive the top rod 26 to push the heat insulation plate 23 to open.

[0051] Here, the width of the highest point of the wavy arc of the limiting block 34 is greater than the width of the arc block 32. This is intended to drive the arc block 32 to slide back and forth in the area of ​​the highest slope of the limiting block 34 when the power supply 22 is too hot, thereby forming an active airflow and improving the heat dissipation effect.

[0052] The sound wave generator 43 is a device that emits sound waves of a specific frequency, and the sound outlet of the sound wave generator 43 is located at the lower end of the inner cavity of the floating ring 10.

[0053] Preferably, in order to ensure that the sound wave generator 43 can successfully drive away aquatic organisms without affecting the person in distress, the sound wave generator 43 should emit low-frequency pulses with a frequency of 20 to 50 Hz, and the float ring 10 should be slightly thinned at the sound outlet of the sound wave generator 43 (the thinning should not have a significant impact on the overall strength of the float ring 10) so that the sound waves can pass through the float ring 10 better and be transmitted outward.

[0054] To ensure smooth subsequent maintenance and power supply 22 disassembly and replacement, multiple inspection ports should be opened on the surface of the float ring 10. The width of the inspection ports should be greater than the overall length of the mounting box 21, and the inspection port area should be sealed to prevent liquid from seeping into the device and causing damage.

[0055] In this embodiment, under normal conditions, if the ambient temperature is too low, the heat insulation plate 23 is attached to the surface of the power supply 22, forming a sealed space with the mounting box 21 to keep the power supply 22 warm and prevent damage to the power supply 22 due to low ambient temperature. When the ambient temperature is too high or the operating temperature of the power supply 22 is too high, the drive component 30 drives the arc block 32 to slide on the surface of the limit block 34, which drives the push plate 31 to move, causing the top rod 26 to move and push the heat insulation plate 23 to open, allowing the power supply 22 to contact the outside air for heat dissipation. After the float ring 10 falls into the water, the sound wave generator 43 will emit low-frequency sound waves into the water through the float ring 10 to disperse surrounding organisms and prevent organisms from approaching and causing panic among the rescuers, thus affecting the rescue work.

[0056] Secondly, please refer to it again. Figures 1 to 2 Four sets of rotors 11 are installed at the four corners of the outer end of the floating ring 10, and protective nets are provided at both the upper and lower ends of the rotors 11 to prevent the rotors 11 from being interfered with by external materials during the rescue and affecting the rescue efficiency.

[0057] The upper and lower ends of the inner cavity of the floating ring 10 are fixedly installed with guide rails 12, and the mounting ring 13 is slidably connected to the inner cavities of the upper and lower guide rails 12. The upper and lower ends of the mounting ring 13 are provided with spherical grooves, and ball bearings 14 are rolled in the spherical grooves. The purpose is to use the ball bearings 14 to reduce the friction when the mounting ring 13 slides, so that the mounting ring 13 rotates more smoothly.

[0058] It should be noted that multiple devices, such as GPS locators and cameras, are installed on the outside of the floating ring 10, and these devices, along with the rotor 11, are electrically connected to the electronic control assembly 40 to ensure the normal operation of the device.

[0059] In this embodiment, when the device is running, the rotor 11 drives the float ring 10 to fly closer to the person in distress. When switching the heat preservation or heat dissipation mode of the power supply 22, the added ring 13 will reduce the friction between itself and the float ring 10 through the ball bearings 14 when it rotates.

[0060] Secondly, please refer to it again. Figures 3 to 5 and Figures 7 to 8 The upper end of the heat insulation plate 23 is hinged to the upper end of the inner cavity of the mounting box 21, while the lower end of the heat insulation plate 23 is rotatably connected to the lower end of the inner cavity of the mounting box 21 through a ball bearing. At the same time, the lower end of the heat insulation plate 23 passes through the lower end of the inner cavity of the mounting box 21 and extends out of the mounting box 21. The temperature control assembly 20 also includes a drive plate 24, which is fixedly connected to the lower end of the part of the heat insulation plate 23 that extends out of the mounting box 21.

[0061] The heat insulation board 23 is divided into three layers: an inner layer 231, a middle layer 232, and a protective layer 233. The innermost part that is in contact with the power supply 22 is the heat insulation layer 231. The outer side of the heat insulation layer 231 is fixedly connected to the heat insulation layer 232, and the protective layer 233 is fixedly connected to the outer side of the heat insulation layer 232.

[0062] It should be noted that the edges of the heat insulation board 23 are rounded so that the heat insulation board 23 can rotate smoothly on the outside of the mounting box 21.

[0063] The mounting box 21 has a disassembly port on the side facing the mounting ring 13, which is designed to facilitate the disassembly and assembly of the power supply 22;

[0064] The heat-conducting layer 231 of the heat insulation plate 23 is preferably made of ceramic material, while the heat insulation layer 232 is preferably made of aerogel material. The purpose is to use the heat insulation layer 232 to isolate the heat transfer when the ambient temperature is low, so as to avoid affecting the capacity of the power supply 22. The protective layer 233 is a hard alloy with low density, which is preferably a magnesium alloy in this embodiment. The purpose is to use the protective layer 233 to protect the heat insulation layer 232.

[0065] The mounting box 21 and the power supply 22 installed inside it are each equipped with four sets, which are evenly distributed on the outside of the mounting ring 13, thereby ensuring the balance and stability of the floating ring 10 and avoiding the impact of uneven gravity distribution inside the floating ring 10 on flight stability.

[0066] In this embodiment, in a low-temperature environment, the heat insulation plate 23 is closed, sealing the mounting box 21, thereby keeping the power supply 22 warm. Under the condition of heat preservation, the heat insulation layer 232 isolates the external temperature, preventing the low ambient temperature from affecting the power storage of the power supply 22.

[0067] Secondly, please refer to it again. Figures 6 to 7 and Figure 9 The temperature control component 20 also includes multiple sets of limiting tubes 25, which are evenly and fixedly installed at the lower end of the mounting box 21. Multiple sets of push rods 26 are slidably connected to the inner cavity of the limiting tubes 25. The ends of the multiple sets of push rods 26 away from the drive plate 24 are all fixedly connected to the middle of the push plate 31. The end of the push rod 26 near the heat insulation plate 23 is opposite to the drive plate 24. A through groove is opened on the side of the limiting tube 25, and a protruding plate is provided on the end of the push rod 26 facing the through groove. The protruding plate extends out of the through groove of the limiting tube 25. A pull rope 27 is fixedly connected to the side of the protruding plate facing the drive plate 24. The other end of the pull rope 27 is fixedly connected to the drive plate 24.

[0068] The push rod 26 is a T-shaped long rod, and the protruding convex plate of the push rod 26 is slidably connected in the through groove on the side of the limiting tube 25. The purpose is to use the through groove and the convex plate to limit the range of motion of the push rod 26, so that the push rod 26 can only slide within the limiting tube 25.

[0069] It should be noted that the end of the push rod 26 away from the drive plate 24 extends out of the limiting tube 25, and the length of the part extending out of the limiting tube 25 is greater than the distance between the push rod 26 and the drive plate 24. This is intended so that when the end of the push rod 26 away from the drive plate 24 is completely pushed into the inner cavity of the limiting tube 25 by the push plate 31, the other end of the push rod 26 is sufficient to push the drive plate 24 to open, thereby limiting the range of motion of the push rod 26.

[0070] The length of the pull rope 27 is greater than the distance between the push rod 26 and the drive plate 24. This is intended to allow the pull rope 27 to be pre-relaxed when the push rod 26 moves, so as to prevent the drive plate 24 from being unable to rotate due to insufficient length of the pull rope 27 when the push rod 26 pushes the drive plate 24 to rotate. During the process of closing the heat insulation plate 23, the push rod 26 will first disengage from the drive plate 24, but the pull rope 27 will continue to move until it pulls the drive plate 24 and the heat insulation plate 23 to reset, thereby realizing the automatic opening and closing of the heat insulation plate 23.

[0071] In this embodiment, when it is necessary to switch the power supply 22 to the heat dissipation mode, the drive assembly 30 drives the push plate 31 to move, and the push plate 31 pushes the top rod 26 to slide along the inner cavity of the limiting tube 25. At this time, the top rod 26 pushes the drive plate 24, and the drive plate 24 drives the lower end of the heat insulation plate 23 to rotate and open, so that the upper end of the heat insulation plate 23 rotates and opens on the outside of the mounting box 21, allowing the power supply 22 to contact the outside air and be in a heat dissipation state. When it is necessary to switch the power supply 22 back to the heat preservation mode, the drive assembly 30 drives the push plate 31 to reset. At this time, the top rod 26 slides in the inner cavity of the limiting tube 25 and disengages from the drive plate 24, and the pull rope 27 pulls the drive plate 24 to reset the heat insulation plate 23, thus achieving heat preservation of the power supply 22 again.

[0072] Please refer to it again. Figure 2 , Figures 9 to 11 The drive assembly 30 also includes five sets of springs 33, which are evenly and fixedly connected to the side of the push plate 31 facing the drive plate 24, and the other end of each set of springs 33 is fixedly connected to the lower end of the mounting box 21.

[0073] The drive assembly 30 also includes a rack 35, which is fixedly connected to the lower end of the inner ring of the mounting ring 13. A motor 36 is fixedly installed at the lower end of the inner cavity of the floating ring 10. A gear 37 is fixedly connected to the output shaft of the motor 36, and the lower end of the outer ring of the gear 37 meshes in the tooth groove of the rack 35.

[0074] It should be noted that the rack 35 has an arc-shaped structure, and the tooth groove of the gear 37 is matched with the tooth groove of the rack 35 to avoid affecting the rotation of the mounting ring 13;

[0075] Four sets of arc-shaped blocks 32 and limiting blocks 34 are provided, all distributed below the four sets of mounting boxes 21. Thus, a set of motors 36 can drive the four sets of arc-shaped blocks 32 to rotate simultaneously, thereby driving the heat insulation plates 23 on the four sets of mounting boxes 21 to open or close simultaneously.

[0076] In this embodiment, when heat dissipation of the power supply 22 is required, the motor 36 drives the gear 37 to rotate, causing the rack 35 and the mounting ring 13 to rotate. The mounting ring 13 then drives the mounting box 21 and the push plate 31 to slide together, causing the arc-shaped block 32 to slide on the outer surface of the limiting block 34 until the arc-shaped block 32 moves from the lowest end to the highest end of the limiting block 34. This moves the arc-shaped block 32 and the push plate 31, allowing the top rod 26 to move and open the heat insulation plate 23. At this time, the spring 33 compresses and stores force. When it is necessary to switch back to the heat preservation mode, the motor 36 runs in reverse, driving the mounting ring 13 to reset, causing the arc-shaped block 32 to move to the lowest end of the limiting block 34. At this time, the spring 33 rebounds, pushing the push plate 31 to reset, which in turn drives the top rod 26 and the pull rope 27 to reset, pulling the heat insulation plate 23 to close again for heat preservation.

[0077] Please refer to it again. Figure 2 , Figure 4 , Figure 12 The electronic control assembly 40 also includes four sets of control units 41. The four sets of control units 41 are evenly distributed at the lower end of the inner cavity of the floating ring 10. Each of the four sets of control units 41 is electrically connected to a power supply 22 via cables 42. A temperature sensor 44 is fixedly installed at the upper end of the mounting box 21. The probe of the temperature sensor 44 extends into the mounting box 21. The purpose is to use the temperature sensor 44 to detect the real-time temperature of the power supply 22, and then determine whether to dissipate heat or insulate the power supply 22.

[0078] It should be noted that the four control units 41 are also electrically connected to each other via cables 42 to facilitate information transmission;

[0079] The sound wave generator 43 and the motor 36 are symmetrically installed at opposite ends of the floating ring 10 to improve the stability and balance of the floating ring 10.

[0080] The cable 42 is made of a soft and foldable material to prevent damage to the cable 42 during the rotation and displacement of the mounting box 21, which would affect the normal use of the device.

[0081] Preferably, the control unit 41 is a component that controls the operation of the device, and the control unit 41 is connected to the electrical components installed on the floating ring 10, as well as the sound wave generator 43, the motor 36 and the temperature sensor 44.

[0082] In this embodiment, under normal conditions, the control unit 41 controls the operation of the electrical components in the device, and the temperature sensor 44 detects the temperature of the power supply 22 in real time to determine whether the power supply 22 needs to be switched to a heat dissipation or heat preservation state, so as to avoid the power supply 22 being too hot or too cold, which would affect its service life.

[0083] The working principle of this invention is as follows: Under normal conditions, if the ambient temperature is too low, the heat insulation plate 23 is attached to the surface of the power supply 22, forming a sealed space with the mounting box 21 to keep the power supply 22 warm. When it is necessary to dissipate heat from the power supply 22, the motor 36 drives the gear 37 to rotate, causing the rack 35 and the mounting ring 13 to rotate. The mounting ring 13 then drives the mounting box 21 and the push plate 31 to slide together, causing the arc block 32 to slide on the outer surface of the limiting block 34 until the arc block 32 moves from the lowest end to the highest end of the limiting block 34, thereby driving the arc block 32 and the push plate 31 to move. The push plate 31 then pushes the top rod 26 to slide along the inner cavity of the limiting tube 25. At this time, the top rod 26 pushes the drive plate 24, and the drive plate 24 drives the lower end of the heat insulation plate 23 to rotate and open, so that the upper end of the heat insulation plate 23 rotates and opens on the outside of the mounting box 21, allowing the power supply 22 to contact the outside air for heat dissipation. When switching back to the heat preservation mode, motor 36 reverses its direction, causing the mounting ring 13 to reset, moving the arc-shaped block 32 to the lowest end of the limit block 34. At this time, spring 33 rebounds, pushing push plate 31 to reset, which in turn drives top rod 26 and pull rope 27 to reset. Pull rope 27 then pulls drive plate 24 to reset heat insulation plate 23, thus heat preservation of power supply 22 again. When the device is running, the rotor 11 drives the floating ring 10 to fly closer to the person in distress. After the floating ring 10 falls into the water, sound wave generator 43 will emit low-frequency sound waves into the water through the floating ring 10 to disperse surrounding organisms and prevent them from approaching and causing panic in the person in distress, thus affecting the rescue operation.
