Technical Field
[0001] The present invention relates to the technical field of unmanned aerial vehicles, and particularly to an airborne power module for an unmanned aerial vehicle and an unmanned aerial vehicle. Background Art
[0002] An unmanned aerial vehicle, abbreviated as "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device. In fact, UAVs are a general term for unpiloted aircraft. From a technical perspective, they can be classified into: unmanned fixed - wing aircraft, unmanned vertical take - off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi - rotor aircraft, unmanned parafoil aircraft, etc. With the continuous development of electronic technology, UAVs are increasingly used in daily life. Batteries have become the ideal energy source for UAVs because of their light weight, small volume, and stable discharge. However, since UAVs have a large power demand during flight, the existing UAV batteries usually have a large capacity. But during flight, due to the rapid power consumption, the UAV battery will quickly heat up, leading to certain safety hazards. Moreover, as the UAV battery heats up, the temperature of the UAV body will also increase, which is not only not conducive to improving the service life of the battery, but also easily damages the valuable components in the UAV body. In addition, due to the large power consumption of UAVs, the battery needs to be replaced frequently. How to replace the battery quickly and stably is particularly crucial.
[0003] UAV batteries generally use multiple groups of battery cells. During use, heat accumulation is likely to occur between multiple groups of battery cells. If not discharged in time, it will affect the battery performance. And during the charging process of UAV batteries, fast charging is mostly used. Fast charging also easily causes the battery to heat up. Since hot air has a lower density and rises, there is a temperature difference between the upper and lower battery cells, which affects the charging efficiency and may even cause the battery to bulge, affecting the charging safety.
[0004] For example, a UAV battery and a UAV with the publication number CN110884667A include a battery compartment, a battery body, a pressing bladder, and a ventilation mechanism. The lower surface of the inner part of the battery compartment is fixedly installed with a pressing bladder; the upper surface of the pressing bladder is fixedly connected to the battery body; ventilation mechanisms are provided on both sides of the battery body; the ventilation mechanism includes a clamping plate and a connecting pipe; two clamping plates are set as a group. The middle part of the clamping plate is inlaid with a connecting pipe. The upper and lower ends of the clamping plate are slidably connected to the left and right side walls of the battery compartment through springs; the connecting pipe is made of rubber material, and the inside of the connecting pipe is hollow; This is mainly used to solve the problems that the existing UAV batteries will generate a large amount of heat during the flight of the UAV, resulting in safety hazards and being prone to fire, and at the same time, when the UAV battery heats up, it will cause the temperature of the UAV body to rise and easily damage the valuable components inside it.
[0005] The above technical solution has some problems in practical applications. Although this technical solution can solve the problem of heat accumulation in the drone battery during flight, its heat dissipation structure is complex, which is not conducive to the application of the battery on the drone, and the battery cannot be quickly disassembled and replaced; moreover, it is impossible to dissipate heat from multiple groups of batteries; during the ascent of the drone, the battery increases the wind resistance of the drone, affecting flight safety, and the battery is prone to uneven heat distribution during charging, affecting charging efficiency and charging safety.

[0018] The technical effects and advantages of the present invention:
[0019] 1. By providing a power supply base and a power supply compartment in the present invention, the power supply base is located in the middle of the UAV body. The power supply compartment can be inserted into the interior of the power supply base to achieve the rapid installation of the power supply compartment. Moreover, the power supply compartment is designed as a regular hexagon structure. The design of the regular hexagon structure can ensure that the power supply compartment is accurately and quickly inserted into the power supply base and will not rotate after being inserted into the power supply base, facilitating the rapid replacement of the power supply compartment. By arranging a ventilation groove in the middle of the power supply compartment, during the flight of the UAV body with the power supply compartment, air passes through the ventilation groove and through the power supply compartment to achieve heat dissipation and cooling of the power supply battery cells inside the power supply compartment, thus ensuring rapid heat dissipation of the power supply compartment without affecting its rapid disassembly and assembly.
[0020] 2. By arranging a power supply installation groove in the middle of the power supply base, multiple limiting blocks are arranged inside the power supply installation groove, and a positioning groove is arranged on the outer side of the power supply compartment. The limiting blocks can be inserted into the positioning groove to lock the position of the power supply compartment, thereby ensuring the stability of the power supply compartment during the flight of the UAV body. By arranging a locking block that can move up and down on one side of the limiting block, the locking block can lock the position of the limiting block, thereby ensuring the stable cooperation between the limiting block and the positioning groove. By arranging a movable rod that can move up and down in the middle of the leg, when the UAV lands, the movable seat is squeezed and moves upward, causing the movable frame to relax but not unlock the limiting block, facilitating takeoff again, effectively improving the stability of the power supply compartment.
[0021] 3. By arranging a ventilation groove inside the power supply compartment, multiple air guiding grooves are arranged on the inner sidewall of the ventilation groove. The air guiding grooves are connected to the battery cell installation groove through through grooves. During the flight of the UAV, the airflow passes through the ventilation groove and the air guiding grooves, and the high-speed flowing airflow in the air guiding grooves can take out the heat generated by the operation of the power supply battery cells through the through grooves, improving the heat dissipation effect of the power supply battery cells inside the power supply compartment.
[0022] 4. By arranging a heat dissipation component in the power supply compartment, the present invention effectively improves the heat dissipation effect during flight. During use, the limiting block squeezes the push rod to make the synchronous rod slide upward, causing multiple heat dissipation fins to be inclined, guiding the airflow through the air guide groove during flight, reducing the wind resistance of the drone during flight, and making the heat dissipation fins horizontal during the battery charging process, reducing the concentration of hot air at the top of the air guide groove, preventing temperature differences between the upper and lower ends of the power supply battery core, and improving the charging safety.

[0037] Embodiment 1, as Figures 1 to 12 shown, according to the drone-mounted power supply module and drone provided by the present invention, its essence is a drone-mounted power supply composed of a power supply base 2 and a power supply compartment 4. The power supply base 2 is integrated in the middle of the drone body 1, and the power supply compartment 4 can be installed inside the power supply base 2 by plugging, so as to realize the quick disassembly and assembly of the power supply compartment 4. Moreover, a ventilation groove 20 and an air guiding groove 21 are provided in the middle of the power supply compartment 4. During the flight of the drone with the power supply compartment 4, the airflow passes through the ventilation groove 20 and the air guiding groove 21, taking out the heat generated by the operation of the power supply battery cell 14 inside the power supply compartment 4, so as to achieve the effect of heat dissipation and temperature reduction.
[0038] In the specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment, and no special limitation is made in this embodiment.
[0039] In this embodiment, the drone-mounted power supply module and drone include:
[0040] The drone body 1, which has a frame for installing the rotor. It should be noted that the drone body 1 also includes the propeller for providing power, the flight controller for controlling the flight of the drone, and related components.
[0041] The power base 2 is located in the middle of the UAV body 1. A power installation slot 3 is provided in the middle of the power base 2, and the power installation slot 3 is configured as a regular hexagon structure; the limiting slot 15 and the limiting block 5. The limiting slot 15 is provided at the inner top end of the power installation slot 3. There are multiple limiting blocks 5, and they are all located inside the limiting slot 15. The limiting block 5 is configured as an "L" shape, and the bottom end of the side of the limiting block 5 close to the middle of the power installation slot 3 is an inclined structure. A spring is provided between the limiting block 5 and the limiting slot 15, and the spring is used to apply a thrust to the limiting block 5 so that it is inserted into the positioning slot 16; the positioning slot 16. There are multiple positioning slots 16, and they are arranged around the outer side wall top end of the power bin 4. The limiting block 5 can be inserted into the positioning slot 16 to limit the position of the power bin 4 in the power installation slot 3; the movable frame 6 is slidably arranged at the upper end of the battery base, and multiple stepped bosses 7 are fixedly connected to the inner side thereof. The stepped bosses 7 correspond to the limiting blocks 5 one by one; the locking slot 17 is provided at the notch of the limiting slot 15. The top end of the limiting block 5 is slidably arranged inside the locking slot 17. The stepped boss 7 is used to be inserted into the locking slot 17 and limit the movement of the limiting block 5 so that the limiting block 5 is locked in the positioning slot 16.
[0042] Specifically, it further includes; multiple legs 8 are all arranged around the outer side of the power base 2 and are fixedly connected to the power base 2. The legs 8 are configured as hollow structures. The bottom of the legs 8 is vertical, the upper part is inclined and fixed to the bottom of the UAV body 1, and the middle part is bent; the movable rod 9 is slidably arranged inside the leg 8. The movable rod 9 can slide inside the leg 8. The movable rod 9 is divided into a flexible section 91 and two rigid sections 92. The two ends of the flexible section 91 are fixedly connected to the rigid sections 92.
[0043] The pin rod 28 and the connecting frame 29. The pin rod 28 is provided at the top end of the movable rod 9, and the connecting frame 29 is provided at the bottom end of the movable arm. The pin rod 28 is slidably arranged inside the connecting frame 29. The movable rod 9 can drive the movable frame 6 to move up and down through the pin rod 28 and the connecting frame 29.
[0044] More specifically, it further includes; the fixed sleeve 18 and the movable seat 19. The fixed sleeve 18 is fixedly arranged at the bottom end of the leg 8. The movable seat 19 is arranged inside the fixed sleeve 18 and is located at the bottom end of the movable rod 9. A spring is provided between the movable seat 19 and the fixed sleeve 18.
[0045] The power bin 4 is located inside the power installation slot 3. The power bin 4 is configured as a regular hexagon structure, and both ends of the power bin 4 are provided with rounded corners. The setting of the rounded corners facilitates the power bin 4 to squeeze the limiting block 5 during the insertion process to make it move.
[0046] A ventilation groove 20 is provided inside the power supply compartment 4 and is arranged between multiple battery cell installation grooves 13; a plurality of air guiding grooves 21 are provided and are arranged around the inner wall of the ventilation groove 20, and the plurality of air guiding grooves 21 are respectively arranged in a staggered manner with the multiple battery cell installation grooves 13; a transition cavity 22 is located at the inner top end of the power supply compartment 4, and the transition cavity 22 is communicated with the ventilation groove 20.
[0047] A sieve plate 26 is fixedly connected to the top end of the transition cavity 22. Ventilation holes for communicating with the transition cavity 22 are provided at the bottom of the sieve plate 26 to prevent sundries from entering the power supply compartment 4.
[0048] A guiding groove 23 and a guiding plate 24. The guiding groove 23 is arranged in the middle of the outer side wall of the power supply compartment 4, the guiding plate 24 is arranged inside the guiding groove 23, the guiding plate 24 is arranged in an arc-shaped structure, and the guiding plate 24 is an elastic plate.
[0049] A pressing groove 25 is arranged at the bottom end of the inner side wall of the power supply installation groove 3 and is adapted to the guiding plate 24. The guiding plate 24 can be inserted into the pressing groove 25 to determine the position correspondence between the power supply compartment 4 and the power supply installation groove 3. When the guiding plate 24 is squeezed, it can deform along the guiding groove 23 and can completely enter the guiding groove 23 when deformed to a certain extent, so as to facilitate the insertion of the power supply compartment 4 into the power supply installation groove 3.
[0050] Heat dissipation fins 30 are arranged on the outside of the power supply compartment 4, and the edges of the heat dissipation fins 30 are flush with the outer surface of the power supply compartment 4 to improve the heat dissipation effect.
[0051] Specifically, it further includes a conductive female seat 11, which is located inside the power supply installation groove 3 and is arranged in a "<" shape. The conductive female seat 11 is made of an elastic metal sheet and has electrical conductivity.
[0052] A conductive male seat 12 is located in the middle of the outer side wall of the power supply compartment 4. After the power supply compartment 4 is inserted into the power supply installation groove 3, the conductive male seat 12 is attached to the conductive female seat 11. It should be noted that the conductive female seat 11 is connected to the circuit in the UAV body 1.
[0053] A plurality of battery cell installation grooves 13 are provided and are all located inside the power supply compartment 4. The battery cell installation grooves 13 are arranged in an isosceles trapezoid structure.
[0054] A sealing cover plate 27 is detachably installed at the notch of the battery cell installation groove 13.
[0055] A power supply battery cell 14 is located inside the battery cell installation groove 13, and the power supply battery cell 14 is electrically connected to the conductive male seat 12 through a wire.
[0056] It should be noted that the power cell 14 is set as a trapezoidal structure corresponding to the cell installation groove 13. The power cell 14 is composed of multiple cells, and the outside of the multiple cells is wrapped with thermal conductive glue. The thermal conductive glue is in a trapezoidal structure. The sealing cover plate 27 is fixed by bolts or other means. By removing the sealing cover plate 27, the power cell 14 is exposed to facilitate the replacement and repair of the power cell 14.
[0057] When using the on-board power module and the drone of this embodiment, the power bin 4 can be inserted into the power installation groove 3 from top to bottom or from bottom to top. After the power bin 4 is inserted in place, the positioning groove 16 on the outside of the power bin 4 is aligned with the limiting block 5 in the power installation groove 3, and the limiting block 5 is inserted into the positioning groove 16 under the action of the spring to lock the position of the power bin 4.
[0058] After the drone body 1 takes off, the landing gear 8 is separated from the ground. At this time, the spring exerts a thrust on the movable seat 19, causing the movable seat 19 to drive the corresponding rigid section 92 to move downward, and at the same time, the flexible section 91 pulls the upper rigid section 92 to move downward synchronously. The movable rod 9 drives the stepped boss 7 to move downward through the movable frame 6 so that the stepped boss 7 is inserted between the locking groove 17 and the limiting block 5 to lock the position of the limiting block 5. At this time, the limiting block 5 is locked in the positioning groove 16, and the power bin 4 is locked in the power installation groove 3.
[0059] After the drone body 1 lands, the landing gear 8 is in contact with the ground. At this time, the movable seat 19 moves upward under the reaction force of the ground, and the lower rigid section 92 slides upward under the extrusion of the ground, relaxing the flexible section 91. At this time, the stepped boss 7 will not slide out of the locking groove 17 and disengage from the limiting block 5, avoiding the need to lock the limiting block 5 again when the drone takes off again. When it is necessary to remove the power bin 4, it is necessary to first manually pull the movable frame 6 upward to disengage the stepped boss 7 from the limiting block 5, and then pull the upper end of the power bin 4 upward, so that the notch of the positioning groove 16 presses the inclined surface on one side of the limiting block 5, so that the limiting block 5 slides horizontally and separates from the positioning groove 16. At this time, the limit of the power bin 4 can be released, and at this time, the power bin 4 can be taken out upward, avoiding that after the drone lands on an uneven ground, the stepped boss 7 directly separates from the limiting block 5, causing the power bin 4 to be squeezed to one side, making it difficult for the stepped boss 7 to be inserted into the locking groove 17 after takeoff and resulting in unstable battery fixation during flight.
[0060] During the flight of the power supply compartment 4 following the drone body 1, the air flow passes through the sieve plate 26 and the transition cavity 22 and enters the ventilation groove 20, and then is discharged through the air guiding groove 21. During this process, the gas flow rate in the air guiding groove 21 is relatively large, and the air flow in the air guiding groove 21 discharges the heat generated by the operation of the power supply battery 14 in the battery installation groove 13 under the Venturi effect, so as to realize the heat dissipation and temperature reduction of the power supply battery 14. At the same time, the heat dissipation fins 30 on the outside of the power supply compartment 4 exchange heat with the air, and the heat dissipation fins 30 discharge the heat on the power supply battery 14 through heat transfer to achieve the effect of heat dissipation and temperature reduction.
[0061] Embodiment 2. In summary, during the actual use, it is found that when the drone rapidly ascends in the vertical direction and ascends in a tilted direction to one side, the air flow passing through the ventilation groove 20 and the air guiding groove 21 causes a relatively large wind resistance to the ascent of the drone, and the power supply compartment 4 is affected by the air flow, causing the drone body 1 to vibrate, which affects flight safety. In addition, the drone battery generally uses fast charging to meet the usage requirements. When the power supply battery 14 is rapidly charged, since the power supply compartment 4 is passive in heat dissipation, the heat generated by the heating of the power supply battery 14 accumulates at the top of the air guiding groove 21, resulting in a temperature difference between the upper and lower sides of the power supply battery 14, which affects the charging safety. Therefore, the relevant components of this device are further improved.
[0062] Specifically, as Figure 4 And Figures 10 to 12 , it further includes a heat dissipation component 10, which is placed in the power supply compartment 4. The heat dissipation component 10 includes:
[0063] Synchronization rod 101, which is arranged in the middle of the power supply compartment 4 and can slide relative to the power supply compartment 4. The synchronization rod 101 is placed in the ventilation slot 20, and the top of the synchronization rod 101 is placed in the transition cavity 22. The synchronization rod 101 does not fill the ventilation slot 20 completely, so that air can still enter the air guiding slot 21 through the ventilation slot 20; Air guiding fins 102, of which there are multiple. Each air guiding fin 102 is rotatably connected to the synchronization rod 101, and the middle part of the air guiding fin 102 is slidably connected to the power supply compartment 4. Each air guiding fin 102 is placed in the corresponding air guiding slot 21 and is slidably matched with the inner wall of the corresponding air guiding slot 21. A rectangular notch is opened in the middle of the air guiding fin 102, and a convex platform is arranged at the position of the air guiding slot 21 corresponding to the rectangular notch, so as to limit the position of the air guiding fin 102 and achieve the purpose of flipping; Push rod 103, which is slidably connected to the middle of the battery base and corresponds to the limiting block 5 one by one. One end of the push rod 103 penetrates the positioning slot 16, and when the limiting block 5 slides, it can squeeze the push rod 103 to make it slide into the transition cavity 22; Connecting rods 104, of which there are multiple and are all rotatably connected to the upper end of the synchronization rod 101. The other end of each connecting rod 104 is rotatably connected to the corresponding push rod 103. It should be noted that the upper end of the synchronization rod 101 is higher than the sliding position of the push rod 103, so that when the push rod 103 slides into the transition cavity 22, the synchronization rod 101 is pushed to slide upward through the connecting rod 104, and the heat dissipation fins are driven to flip; Reset tension spring 105, which is fixedly connected to the bottom of the push rod 103, and the other end is fixedly connected to the bottom of the power supply compartment 4. When the power supply compartment 4 is removed from the power supply installation slot 3, the reset tension spring 105 pulls the synchronization rod 101 to reset, so that the air guiding fins 102 are flipped to the horizontal state; The synchronization rod 101 slides up and down to adjust the angle of the air guiding fins 102; The end face of the limiting block 5 can squeeze the push rod 103.
[0064] More specifically, the stepped convex platform 7 is divided into a locking section 71 and a pressing section 72. The locking section 71 is placed below the pressing section 72, and the pressing section 72 is an inclined plane.
[0065] When using the airborne power module and the drone of this embodiment, when the drone takes off, the legs 8 are separated from the ground. At this time, the locking section 71 slides down along the locking groove 17 and locks the limiting block 5. As the stepped convex platform 7 slides further downward, the pressing section 72 presses the limiting block 5 further toward the power supply compartment 4. At this time, the push rod 103 slides inward toward the power supply compartment 4, and the synchronization rod 101 slides upward through the connecting rod 104. At this time, multiple air guiding fins 102 are flipped to form an included angle, as Figure 10As shown, during the upward movement of the drone, the airflow is guided by the air guide fins 102 to discharge the power supply compartment 4 while taking away the heat of the power supply cell 14. Since the air guide fins 102 have a certain angle, air can more easily pass through the air guide slots 21, reducing the wind resistance when the drone ascends. At the same time, by reducing the impact of the airflow on the bottom of the air guide slots 21, the vibration of the drone during flight is reduced, improving flight safety.
[0066] When the power supply compartment 4 is removed for charging, the reset tension spring 105 pulls the synchronization rod 101 to reset. At this time, the air guide fins 102 return to the horizontal state, as Figure 11 shown, enabling the power supply cell 14 to discharge heat through the air guide slots 21 during charging and reducing the concentration of hot air at the top of the air guide slots 21, preventing a temperature difference between the upper and lower ends of the power supply cell 14 and improving safety during fast charging.
[0067] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
