Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle airborne power supply module and the unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. UAVs are actually a general term for unmanned aerial vehicles. From a technical perspective, they can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. With the continuous development of electronic technology, drones are increasingly used in daily life. Batteries have become an ideal energy source for drones because of their light weight, small size, and continuous and stable discharge. However, since drones have a large demand for electricity during flight, drone batteries in existing technologies usually have a large capacity. However, during flight, the battery of a drone will heat up quickly due to the rapid power consumption, resulting in certain safety hazards. As the temperature of the drone battery rises, the temperature of the drone body will also rise, which is not only not conducive to improving the battery life, but also easily damages the valuable parts in the drone body. Moreover, since drones consume a lot of electricity, the battery needs to be replaced frequently. How to replace the battery quickly and stably is particularly critical.

[0003] Drone batteries generally use multiple groups of battery cells. During use, heat is easily accumulated between the multiple groups of battery cells. If it is not discharged in time, it will affect the battery performance. In addition, most drone batteries are charged using fast charging, which can also easily make the battery heat up. Since hot air has a lower density, it will rise, resulting in a temperature difference between the upper and lower parts of the battery cell, affecting the charging efficiency and even causing the battery to bulge, affecting charging safety.

[0004] For example, a drone battery and drone with announcement number CN110884667A include a battery compartment, a battery body, a pressing bag and a ventilation mechanism, wherein a pressing bag is fixedly installed on the inner lower surface of the battery compartment; the battery body is fixedly connected to the upper surface of the pressing bag; ventilation mechanisms are provided on both sides of the battery body; the ventilation mechanism includes a clamping plate and a connecting tube; the two clamping plates are arranged as a group, a connecting tube is embedded and installed in the middle of the clamping plate, and 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 tube is made of rubber material, and the interior of the connecting tube is arranged to be hollow; the present invention is mainly used to solve the problem that the existing drone battery will generate a lot of heat during the flight of the drone, resulting in safety hazards and prone to fire, and at the same time, when the drone battery heats up, the temperature of the drone body will increase, which may cause damage to the valuable components inside it.

[0005] The above technical solution has some problems in practical application. Although the technical solution can solve the problem of heat accumulation of UAV batteries during flight, its heat dissipation structure is complicated, which is not conducive to the application of batteries on UAVs, and the batteries cannot be quickly disassembled and replaced; and it is impossible to dissipate heat for multiple groups of batteries; during the ascent of the UAV, the batteries increase the wind resistance of the UAV, affecting flight safety, and the batteries are prone to uneven heat distribution during charging, affecting charging efficiency and charging safety.

[0020] 2. The present invention provides a power installation groove in the middle of the power base, multiple limit blocks are provided inside the power installation groove, and a positioning groove is provided on the outside of the power supply compartment. The limit block 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.

The power base 2 is integrated in the middle of the drone body 1, and the power compartment 4 can be installed inside the power base 2 by plugging in to achieve rapid disassembly and assembly of the power compartment 4. In addition, a ventilation groove 20 and an air guide groove 21 are provided in the middle of the power compartment 4.

[0039] In this embodiment, the UAV onboard power supply module and the UAV include:

[0040] The drone body 1 has a frame for mounting a rotor. It should be noted that the drone body 1 also includes blades for providing power, a flight controller for controlling the flight of the drone, and related components.

[0041] A power base 2 is located in the middle of the drone body 1, and a power installation slot 3 is provided in the middle of the power base 2, and the power installation slot 3 is set as a regular hexagonal structure; a limit slot 15 and a limit block 5, the limit slot 15 is set at the inner top of the power installation slot 3, a plurality of limit blocks 5 are provided and all are located inside the limit slot 15, the limit block 5 is set as an "L"-shaped structure, and the bottom end of one side of the limit block 5 close to the middle of the power installation slot 3 is set as an inclined structure, a spring is provided between the limit block 5 and the limit slot 15, and the spring is used to apply thrust to the limit block 5 so that it is inserted into the positioning slot 16; the positioning slot 16 , which is provided with multiple and surrounding the top of the outer wall of the power supply compartment 4, the limit block 5 can be inserted into the positioning groove 16 to limit the position of the power supply compartment 4 in the power supply installation groove 3; the movable frame 6, which is slidably arranged at the upper end of the battery base, and a plurality of stepped bosses 7 are fixedly connected to the inner side thereof, and the stepped bosses 7 correspond one by one to the limit block 5; the locking groove 17, the locking groove 17 is arranged at the notch of the limit groove 15, and the top end of the limit block 5 is slidably arranged inside the locking groove 17, and the stepped boss 7 is used to be inserted into the locking groove 17 and limit the movement of the limit block 5, so that the limit block 5 is locked in the positioning groove 16.

[0042] Specifically, it also includes: a plurality of legs 8, which are all arranged around the outside of the power base 2 and fixedly connected to the power base 2, and the legs 8 are set to be a hollow structure, the bottom of the legs 8 is vertical, the upper part is inclined and fixed to the bottom of the drone body 1, and the middle part is bent; a movable rod 9, which is slidably arranged inside the legs 8, and the movable rod 9 can slide in the legs 8. The movable rod 9 is divided into a flexible section 91 and two rigid sections 92, and the two ends of the flexible section 91 are fixedly connected to the rigid section 92.

[0043] The pin rod 28 and the connecting frame 29 are arranged at the top end of the movable rod 9, and the connecting frame 29 is arranged 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 also includes a fixed sleeve 18 and a movable seat 19, the fixed sleeve 18 is fixed at the bottom end of the leg 8, the movable seat 19 is arranged inside the fixed sleeve 18 and at the bottom end of the movable rod 9, and a spring is arranged between the movable seat 19 and the fixed sleeve 18.

[0045] The power supply compartment 4 is located inside the power supply installation slot 3. The power supply compartment 4 is set to a regular hexagonal structure, and both ends of the power supply compartment 4 are provided with rounded corners. The setting of the rounded corners facilitates the squeezing of the limit block 5 to make it move during the insertion of the power supply compartment 4.

[0046] The ventilation groove 20 is arranged inside the power supply compartment 4, and the ventilation groove 20 is arranged between multiple battery cell mounting grooves 13; the air guide groove 21 is provided with multiple and surrounds the inner wall of the ventilation groove 20, and the multiple air guide grooves 21 are respectively staggered with the multiple battery cell mounting grooves 13; the transition cavity 22 is located at the inner top of the power supply compartment 4, and the transition cavity 22 is connected to the ventilation groove 20.

[0047] The sieve plate 26 is fixedly connected to the top of the transition chamber 22 . A ventilation hole is provided at the bottom of the groove of the sieve plate 26 for communicating with the transition chamber 22 to prevent debris from entering the power supply compartment 4 .

[0048] The guide groove 23 and the guide plate 24, the guide groove 23 is arranged in the middle of the outer wall of the power supply compartment 4, the guide plate 24 is arranged inside the guide groove 23, the guide plate 24 is arranged as an arc structure, and the guide plate 24 is arranged as an elastic plate.

[0049] The pressing groove 25 is arranged at the bottom end of the inner wall of the power supply installation groove 3 and is adapted to the guide plate 24. The guide 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 guide plate 24 is squeezed, it can be deformed along the guide groove 23, and when it is deformed to a certain extent, it can completely enter the guide groove 23, so as to facilitate the insertion of the power supply compartment 4 into the power supply installation groove 3.

[0050] The 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, so as to improve the heat dissipation effect.

[0051] Specifically, it also includes a conductive female seat 11, which is located inside the power supply installation slot 3 and is set to a "<"-shaped structure. The conductive female seat 11 is set to be a metal sheet with elasticity and has conductive properties.

[0052] The conductive male socket 12 is located in the middle of the outer wall of the power compartment 4. After the power compartment 4 is inserted into the power installation slot 3, the conductive male socket 12 fits with the conductive female socket 11. It should be noted that the conductive female socket 11 is connected to the circuit in the drone body 1.

[0053] There are multiple battery cell installation slots 13 , all of which are located inside the power supply compartment 4 . The battery cell installation slots 13 are configured as isosceles trapezoidal structures.

[0054] A sealing cover plate 27 is detachably mounted at the notch of the battery cell mounting groove 13 .

[0055] The power cell 14 is located inside the cell installation slot 13 , and the power cell 14 is electrically connected to the conductive male socket 12 via a wire.

[0056] It should be noted that the power cell 14 is configured as a trapezoidal structure corresponding to the cell mounting groove 13. The power cell 14 is composed of a plurality of cells. The outer sides of the plurality of cells are wrapped with thermal conductive adhesive. The thermal conductive adhesive is a trapezoidal structure. The sealing cover plate 27 is fixed by bolts or the like. The power cell 14 is exposed by removing the sealing cover plate 27 to facilitate replacement and repair of the power cell 14.

[0057] When using the drone onboard power supply module and drone of this embodiment, the power supply compartment 4 can be inserted into the power supply installation slot 3 from top to bottom or from bottom to top. After the power supply compartment 4 is plugged into place, the positioning groove 16 on the outside of the power supply compartment 4 is aligned with the limit block 5 in the power supply installation slot 3. The limit block 5 is inserted into the positioning groove 16 under the action of the spring to lock the position of the power supply compartment 4.

[0058] After the UAV body 1 takes off, the legs 8 are separated from the ground. At this time, the spring applies a thrust to the movable seat 19, so that the movable seat 19 drives the corresponding rigid section 92 to move downward. At the same time, the flexible section 91 pulls the upper rigid section 92 downward synchronously, and 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 limit block 5 to achieve locking of the position of the limit block 5. At this time, the limit block 5 is locked in the positioning groove 16, and the power supply compartment 4 is locked in the power supply installation groove 3.

[0059] After the drone body 1 lands, the legs 8 are in contact with the ground. At this time, the movable seat 19 moves upward under the reaction force of the ground, and the rigid section 92 at the lower end slides upward under the pressure of the ground, so that the flexible section 91 relaxes. At this time, the stepped boss 7 will not slide out of the locking groove 17 and disengage from the limit block 5, so as to avoid the need to lock the limit block 5 again when the drone takes off. When the power supply compartment 4 needs to be removed, it is necessary to manually pull the movable frame 6 upward to disengage the stepped boss 7 from the limit block 5, and then pull the upper end of the power supply compartment 4 upward so that the notch of the positioning groove 16 squeezes the inclined surface on one side of the limit block 5, so that the limit block 5 slides horizontally and separates from the positioning groove 16. At this time, the limit of the power supply compartment 4 can be released, and the power supply compartment 4 can be taken out upward to avoid the stepped boss 7 directly separating from the limit block 5 after the drone falls on a non-flat ground, causing the power supply compartment 4 to be squeezed to one side, making it difficult for the stepped boss 7 to be inserted into the locking groove 17 after the go-around, resulting in unstable battery fixation during flight.

[0060] When the power supply compartment 4 follows the UAV body 1 to fly, the airflow passes through the sieve plate 26 and the transition cavity 22 into the ventilation slot 20, and then is discharged through the air guide slot 21. During this process, the gas flow rate in the air guide slot 21 is relatively large. Under the action of the Venturi, the airflow in the air guide slot 21 discharges the heat generated by the power cell 14 in the cell installation slot 13, so as to achieve heat dissipation and cooling of the power cell 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 from the power cell 14 by heat transfer, so as to achieve the effect of heat dissipation and cooling.

[0061] Embodiment 2. In summary, it is found in the actual use process that when the UAV rises rapidly in the vertical direction and rises in a tilted direction to one side, the airflow passes through the ventilation slots 20 and the wind guide slots 21, resulting in a large wind resistance for the UAV to rise, and the power supply compartment 4 is affected by the airflow to cause the UAV body 1 to vibrate, affecting flight safety. UAV batteries generally use fast charging to meet usage requirements. When the power cell 14 is quickly charged, since the power supply compartment 4 is passively dissipated, the heat generated by the power cell 14 is accumulated at the top of the wind guide slot 21, causing a temperature difference between the upper and lower sides of the power cell 14, affecting charging safety. For this reason, the relevant components of the device are further improved.

[0062] Specifically, Figure 4 and Figures 10 to 12 , further comprising a heat dissipation assembly 10, which is disposed in the power supply compartment 4, and the heat dissipation assembly 10 comprises:

[0063] The synchronization rod 101 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 chamber 22. The synchronization rod 101 does not fill the ventilation slot 20, so that air can still enter the air guide slot 21 through the ventilation slot 20; there are multiple air guide fins 102, each of which is rotatably connected to the synchronization rod 101, and the middle of the air guide fin 102 is slidably connected to the power supply compartment 4. Each air guide fin 102 is placed in the corresponding air guide slot 21, and it slides with the corresponding inner wall of the air guide slot 21. A rectangular notch is opened in the middle of the air guide fin 102, and a boss is provided at the position of the air guide slot 21 corresponding to the rectangular notch, so as to limit the position of the air guide fin 102 and achieve the purpose of flipping; a push rod 103 is slidably connected to the middle of the battery base, and corresponds to the limit block 5 one by one. One end of the push rod 103 penetrates the fixed When the limit block 5 slides, it can squeeze the push rod 103 to make it slide into the transition chamber 22; there are multiple connecting rods 104, and they are all rotatably connected to the upper end of the synchronization rod 101, and the other end of each connecting rod 104 is rotatably connected to the corresponding push rod 103. It should be pointed out 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 chamber 22, it is pushed to slide upward synchronously through the connecting rod 104, and drives the heat dissipation fins to flip over; the reset tension spring 105 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 guide fins 102 are flipped to a horizontal state; the synchronization rod 101 slides up and down to adjust the angle of the air guide fins 102; the end face of the limit block 5 can squeeze the push rod 103.

[0064] More specifically, the stepped boss 7 is divided into a locking section 71 and an extrusion section 72 . The locking section 71 is disposed below the extrusion section 72 , and the extrusion section 72 is an inclined surface.

[0065] When the drone airborne power module and the drone of this embodiment are used, when the drone takes off, the outrigger 8 is separated from the ground, at which time the locking section 71 slides downward along the locking groove 17 and locks the limit block 5. As the stepped boss 7 slides further downward, the extrusion section 72 causes the limit block 5 to be further extruded toward the power supply compartment 4. At this time, the push rod 103 slides toward the inside of the power supply compartment 4, and the synchronization rod 101 slides upward through the connecting rod 104. At this time, the multiple wind guide fins 102 flip over to form an angle, such as Fig.10As shown, when the drone subsequently rises, the airflow is guided by the air guide fins 102 to remove the heat from the power cell 14 and discharge it from the power compartment 4. Since the air guide fins 102 have a certain angle, the air can pass through the air guide groove 21 more easily, thereby reducing the wind resistance of the drone when it rises. At the same time, by reducing the impact of the airflow on the bottom of the air guide groove 21, the vibration of the drone during flight is reduced, thereby improving flight safety.

[0066] When the power supply compartment 4 is removed for charging, the reset spring 105 pulls the synchronization rod 101 to reset, and the air guide fins 102 are restored to a horizontal state. Fig.11 As shown, the power cell 14 can discharge heat through the air guide groove 21 during charging, and reduce the concentration of hot air on the top of the air guide groove 21, resulting in a temperature difference between the upper and lower ends of the power cell 14, thereby improving safety during fast charging.

[0067] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
