Description

Technical Field

[0001] The present invention relates to the technical field of UAV batteries, and specifically to a battery device for a UAV with a telescopic solar panel. Background Art

[0002] UAV photovoltaic battery technology is an advanced energy utilization technology that converts solar energy into electrical energy to support the operation of UAVs. With the help of highly efficient photovoltaic panels, it converts sunlight into electricity and stores it in the battery, providing power for UAV flight, equipment operation, etc. It has the advantages of extending the endurance time of UAVs, reducing dependence on traditional power sources, environmental protection and energy conservation, and is widely used in fields such as surveying and mapping, inspection, and logistics distribution. With the continuous improvement of photovoltaic materials and conversion efficiency, its development prospect is very broad.

[0003] Referring to the Chinese patent with the authorized announcement number of CN220935115U, it discloses a battery device for a UAV with a telescopic solar panel. On the assembly inclined surface on the upper surface of the cover plate of this device, battery pack A and battery pack B are arranged in a stepped manner, effectively increasing the utilization rate of the installation space of the battery panel. During the flight of the UAV, the electric push rod is remotely controlled by the remote controller, and the transmission output end of the electric push rod pushes the support frame A and the battery panel A to move synchronously to the outer side position of the battery panel B, then the battery panel B is used in cooperation with the battery panel A, effectively improving the photoelectric conversion effect, extending the endurance time of the storage battery, and improving the service performance.

[0004] However, although the battery panel A in the above device can be telescopically moved, its cover plate, battery panel A, and battery panel B are arranged on the top of the UAV fuselage and occupy a certain space. When not flying, they cannot be hidden and folded, resulting in an overly large volume of the UAV fuselage, which is not convenient for storage or carrying. In addition, during the high-maneuverability flight of the UAV, such as rapid lifting, frequent rapid turning, or flying in a strong wind environment, due to the fact that structures such as the battery panel cannot be hidden and stored and are exposed outside, there is a large wind resistance, which is not conducive to the control of the UAV and the stability of the flight attitude. Summary of the Invention

[0005] In order to solve the technical problems existing in the above-mentioned prior art, the present invention provides a high-temperature test platform for semiconductor chips.

[0006] To achieve the above object, the present invention provides the following technical solution: A battery device for a drone with a telescopic solar panel, including a drone fuselage shell and a photovoltaic panel, further comprising a storage bin embedded in the drone fuselage shell with an opening at the top, a box seat slidably installed in the storage bin, and a top cover seat fixed on the top of the box seat. A first driving mechanism is provided in the storage bin for driving the box seat to perform telescopic adjustment in the vertical direction.

The worm is fixedly connected to the output shaft of the third driving motor. The two worm gears on the same side of the mounting bracket are both meshed with the worm.

[0010] Preferably, diversion openings and heat conducting sheets are provided on the four side walls of the storage bin. The diversion openings communicate with the inside of the drone fuselage shell. The heat conducting sheets are close to the heat sources inside the drone fuselage shell. Diversion holes communicating with the inside of the storage bin are evenly distributed at the bottom of the box seat. Sealing baffles are respectively fixed on both sides of the bottom end of the box seat. Both sealing baffles are slidably connected to the inner wall of the storage bin. A cooling fan is installed in the heat dissipation opening on one side of the box seat. Air inlet openings communicating with the inside of the drone fuselage shell are evenly distributed at the bottom of the drone fuselage shell.

[0011] Preferably, a flow blocking platform is provided at the position corresponding to the air inlet opening at the bottom of the drone fuselage shell.

[0012] Preferably, an installation opening for installing the storage bin is provided at the top of the UAV fuselage shell. Clamping plates are respectively arranged on both sides of the air inlet in the UAV fuselage shell. A clamping opening is formed between the two clamping plates. The base seat at the bottom of the storage bin is correspondingly and fittingly clamped in the clamping opening. The bottom of the base seat and the bottoms of the two clamping plates jointly form a guiding surface for guiding the airflow entering the UAV fuselage shell from the air inlet to both sides.

[0013] Preferably, the first driving mechanism includes a first driving motor, a threaded rod, and a sleeve. The first driving motor is fixed on the inner bottom wall of the storage bin. The threaded rod is fixed on the output shaft of the first driving motor. The sleeve is vertically installed in the box body seat and extends through the bottom end to the lower part of the box body seat. A threaded hole is provided at the bottom of the sleeve, and the sleeve is threadedly and fittingly installed in the threaded hole.

[0014] Preferably, a stop block is installed on the end of the threaded rod extending into the sleeve. The diameter of the stop block is larger than the aperture of the threaded hole.

[0015] Preferably, the second driving mechanism includes a bidirectional screw rod, nut seats, racks, a second driving motor, and gears.

Shaft rods are rotatably installed in both side grooves. First connecting seats are fixed on both shaft rods. Two mounting frames are respectively fixed on the corresponding first connecting seats. The bidirectional screw rod is rotatably installed in the sliding groove. The second driving motor is fixed on one side of the top cover seat, and the output shaft is fixedly connected to one end of the bidirectional screw rod. Two nut seats are respectively limited and slidably installed in the sliding groove and are threadedly sleeved on both sides of the bidirectional screw rod. Racks are fixed to the bottoms of the two nut seats. Gears are fixedly sleeved on both shaft rods, and the gears are meshed with the corresponding side racks.

[0016] Compared with the prior art, the present invention provides a battery device with a telescopic solar panel for a UAV, having the following beneficial effects: (1) In the present invention, the mounting frames with photovoltaic panels installed on both sides are designed to be foldable and retractable, and the box body seat is designed to be telescopic, so that the structure of the photovoltaic power generation part can be hidden and recycled into the UAV fuselage shell, reducing the overall volume of the UAV, facilitating storage and carrying. At the same time, after the structure is hidden, the wind resistance is reduced, which is beneficial to the high maneuverability flight of the UAV, so that it can better perform flight tasks. When the box body seat moves down and retracts to the limit position, the top cover seat and the top of the UAV fuselage shell form a matching streamlined structure, enabling the airflow to flow more smoothly over the surface of the UAV, reducing wind resistance and noise, further ensuring the stability of the flight attitude. At the same time, the top cover seat can block the opening at the top of the storage bin to ensure the sealing integrity of the device interior.

[0017] (2) In the present invention, the third driving motor is respectively used to drive the photovoltaic panels on both sides to rotate and adjust. On the basis of the angle adjustment of the mounting frame driven by the second driving mechanism, the angle adjustment freedom of the photovoltaic panels is higher, the angle adjustment range of the photovoltaic panels can be supplemented and expanded, and thus the photovoltaic panels can be more accurately oriented towards the sun at different times, improving the photoelectric conversion and power supply efficiency. At the same time, the transmission mode of using a worm to engage and drive a worm wheel has a one-way self-locking effect. When the third driving motor is not working, it ensures that the photovoltaic panels will not rotate randomly, helps to maintain the angle of the photovoltaic panels, can withstand large wind resistance and wind pressure, has a high degree of stability, and at the same time avoids excessive load on the output shaft of the third driving motor, ensuring a longer service life of the third driving motor.

[0018] (3) In the present invention, a common heat dissipation flow path and structure are formed in the drone fuselage shell, the storage bin and the box seat through the air inlet, the diversion port, the heat conduction sheet and the diversion holes, which can not only dissipate heat from the inside of the box seat, but also dissipate heat from the inside of the drone fuselage shell, effectively improving the heat dissipation effect of the drone. Using the base seat at the bottom of the storage bin and the two clamping plates to form a guiding surface, the airflow entering the drone fuselage shell from the air inlet can be blocked and diverted to both sides, so that the air bypasses the clamping plates on both sides and then enters the storage bin, thereby expanding the flowing range of the heat dissipation airflow in the drone fuselage shell, ensuring a larger coverage area of the heat dissipation airflow, and further improving the heat dissipation effect on the inside of the drone fuselage shell. Secondly, the base seat and the clamping plates serve both as the installation parts of the storage bin and as the diversion parts of the heat dissipation airflow, killing two birds with one stone.

[0019] (4) The way of using a bidirectional screw to thread-drive the nut seat to move in the present invention has a self-locking effect. When the second driving motor is not working, it avoids the random swing of the mounting frame, helps to maintain the angle of the mounting frame, has a strong wind resistance and a high degree of stability, and at the same time avoids excessive load on the output shaft of the second driving motor when it is not working, ensuring a longer service life of the second driving motor.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0023] This embodiment provides a battery device with a telescopic solar panel for an unmanned aerial vehicle, which includes an unmanned aerial vehicle fuselage shell 1 and a photovoltaic panel 8. It also includes a storage bin 2 embedded in the unmanned aerial vehicle fuselage shell 1 and having an opening at the top, a box seat 3 slidably installed in the storage bin 2, and a top cover seat 4 fixed on the top of the box seat 3. A first driving mechanism 5 is provided in the storage bin 2 for driving the box seat 3 to perform telescopic adjustment in the vertical direction. The top of the storage bin 2 is flush with the top of the unmanned aerial vehicle fuselage shell 1. The top cover seat 4 abuts against the top of the unmanned aerial vehicle fuselage shell 1 and seals the opening at the top of the storage bin 2 to ensure the sealing integrity of the device interior.

[0024] On both sides of the bottom of the top cover seat 4, mounting frames 7 are respectively installed through a second driving mechanism 6 provided inside it. A pair of photovoltaic panels 8 are installed on both mounting frames 7. The second driving mechanism 6 is used for driving the mounting frames 7 on both sides to perform rotational adjustment, enabling deployment or storage.

[0025] In addition, the unmanned aerial vehicle fuselage shell 1 is equipped with a rechargeable battery to provide additional power for the unmanned aerial vehicle, ensuring that the unmanned aerial vehicle can still fly normally when the photovoltaic power generation structure cannot supply power.

[0026] When this battery device is in use, through the operation of the first driving mechanism 5, the box seat 3 is driven to move upward and completely extend out from the opening at the top of the storage bin 2. Then, through the operation of the second driving mechanism 6, the mounting frames 7 on both sides are driven to rotate and deploy, so that the photovoltaic panels 8 can be irradiated by sunlight for normal photovoltaic power generation and power supply. When the unmanned aerial vehicle is stored, in rainy weather, and when the unmanned aerial vehicle needs to fly with high maneuverability, through the operation of the second driving mechanism 6, the mounting frames 7 on both sides are driven to rotate and store. Then, through the operation of the first driving mechanism 5, the entire box seat 3 is driven to move downward and retract into the storage bin 2 until the top cover seat 4 abuts against the tops of the unmanned aerial vehicle fuselage shell 1 and the storage bin 2, realizing the hidden storage of the overall structure of the photovoltaic power generation part. The storage structure state is as Figure 11 shown.

[0027] In this application, the mounting frames 7 with photovoltaic panels 8 installed on both sides are designed to be foldable and retractable, and the box seat 3 is designed to be telescopic, enabling the structure of the photovoltaic power generation part to be hidden and recycled into the unmanned aerial vehicle fuselage shell 1, reducing the overall volume of the unmanned aerial vehicle, facilitating storage and transportation. At the same time, after the structure is hidden, the wind resistance is reduced, which is beneficial to the high - maneuverability flight of the unmanned aerial vehicle, so that it can better perform flight tasks.

[0028] Secondly, when the box seat 3 moves downward and retracts to the limit position, the top cover seat 4 and the top of the unmanned aerial vehicle fuselage shell 1 form a matching streamlined structure, enabling the airflow to flow more smoothly over the surface of the unmanned aerial vehicle, reducing wind resistance and noise, and further ensuring the stability of the flight attitude.

[0029] In addition, the structure formed by the top cover seat 4 and the box body seat 3 is in a T shape. Storage areas 301 for folding and storing the mounting frames 7 are respectively formed on both sides of the box body seat 3 under the top cover seat 4. When the second driving mechanism 6 works, it can drive the two mounting frames 7 to rotate towards both sides respectively, and they can be unfolded outward from the storage areas 301. When folding and storing, the second driving mechanism 6 drives the two mounting frames 7 to rotate into the storage areas 301, so that the mounting frames 7 are stored on both sides of the box body seat 3 in a matching manner, ensuring that the box body seat 3 and the mounting frames 7 can smoothly retract into the storage bin 2.

[0030] In addition, the second driving mechanism 6 can drive the two mounting frames 7 to adjust the angle, so as to ensure that the photovoltaic panels 8 receive a larger sunlight irradiation area.

[0031] As Figures 4 to 7 shown, each mounting frame 7 is provided with two storage grooves 71 for embedding and storing the photovoltaic panels 8. Rotating shafts 72 are rotatably installed in the storage grooves 71. Second connecting seats 73 are fixedly sleeved on the rotating shafts 72. Each photovoltaic panel 8 is respectively fixed on the corresponding second connecting seat 73. One side of the mounting frame 7 has a groove 701. One ends of the two rotating shafts 72 on the mounting frame 7 all penetrate and extend into the groove 701, and worm wheels 93 are fixedly installed on them. A third driving motor 91 is fixed on the inner end wall on one side of the groove 701, and a worm 92 is rotatably installed on the inner end wall on the other side. The worm 92 is fixedly connected with the output shaft of the third driving motor 91. The two worm wheels 93 on the same side of the mounting frame 7 are both meshed with the worm 92.

[0032] By the operation of the third driving motor 91, its output shaft can drive the worm 92 to rotate. The rotating worm 92 meshes with and drives the worm wheels 93 and drives the rotating shafts 72 to rotate. Under the connection action of the second connecting seats 73, it can drive the photovoltaic panels 8 to swing and adjust, facilitating the angle adjustment of the photovoltaic panels 8. At the same time, the photovoltaic panels 8 can also be retracted into the storage grooves 71.

[0033] By respectively using the operation of the third driving motor 91 to drive the photovoltaic panels 8 on both sides to rotate and adjust, on the basis of the second driving mechanism 6 driving the mounting frames 7 to adjust the angle, the degree of freedom of the angle adjustment of the photovoltaic panels 8 is higher, the angle adjustment range of the photovoltaic panels 8 can be supplemented and expanded, and further, the photovoltaic panels can be more accurately oriented towards the sun at different times, improving the photoelectric conversion and power supply efficiency. At the same time, using the transmission method of the worm 92 meshing with and driving the worm wheels 93 has a one-way self-locking effect. When the third driving motor 91 is not working, it ensures that the photovoltaic panels 8 will not rotate randomly, helps to maintain the angle of the photovoltaic panels 8, can withstand a large wind resistance and wind pressure, has a high stability degree, and at the same time avoids excessive load on the output shaft of the third driving motor 91, ensuring a longer service life of the third driving motor 91.

[0034] As Figure 2 andFigure 3 As shown in the figure, the first driving mechanism 5 includes a first driving motor 51, a threaded rod 52 and a sleeve 53. The first driving motor 51 is fixed on the inner bottom wall of the storage bin 2, the threaded rod 52 is fixed on the output shaft of the first driving motor 51, the sleeve 53 is vertically installed in the box body base 3, and the bottom end thereof extends through and below the box body base 3. A threaded hole 531 is provided at the bottom of the sleeve 53, and the sleeve 53 is threadedly matched and installed in the threaded hole 531. By the operation of the first driving motor 51, its output shaft drives the threaded rod 52 to rotate. Under the action of the threaded driving cooperation with the threaded hole 531, the sleeve 53 and the box body base 3 as a whole can be driven to lift and adjust, providing stable driving for the lifting and adjustment of the box body base 3.

[0035] Secondly, a stop block 54 is installed on the end of the threaded rod 52 extending into the sleeve 53. The diameter of the stop block 54 is larger than the aperture of the threaded hole 531. The stop block 54 is used to block and limit, preventing the box body base 3 from moving up excessively and causing the threaded rod 52 to fall off from the threaded hole 531.

[0036] It is worth noting that a surrounding installation space is formed between the inner wall of the box body base 3 and the outer wall of the sleeve 53. A storage battery, an inverter, a wireless transceiver and a processor are installed in this installation space. The storage battery, the inverter and the photovoltaic panel 8 form a solar power generation system for powering the drone. The wireless transceiver, the controller and the remote control form a control system. The specific working principle is the same as that in the reference patent and will not be disclosed in detail in this application. The sleeve 53 separates the threaded rod 52 from the storage battery, the inverter, the wireless transceiver and the processor, providing an effective protection effect.

[0037] Secondly, since a storage battery, an inverter, a wireless transceiver and a processor are installed in the box body base 3, heat will be generated during operation. If the heat accumulates in the box body base 3, it is likely to cause adverse effects. To solve this problem, in the present invention, a heat dissipation fan 33 is installed in the heat dissipation port 302 on one side of the box body base 3. By the operation of the heat dissipation fan 33, the heat in the box body base 3 is sucked and discharged to the outside, thereby providing effective heat dissipation for the inside of the box body base 3. At the same time, the box body base 3 blows the wind outwards from the heat dissipation port 302, which can prevent rainwater from entering the box body base 3 and causing pollution.

[0038] Specifically, diversion openings 21 and heat conducting fins 22 are provided on the four side walls of the storage bin 2. The diversion openings 21 communicate with the inside of the drone fuselage shell 1, and the heat conducting fins 22 are close to the heat source inside the drone fuselage shell 1. Diversion holes 32 communicating with the inside of the storage bin 2 are evenly distributed at the bottom of the box seat 3. Sealing baffles 31 are respectively fixed on both sides of the bottom end of the box seat 3. Both sealing baffles 31 are slidably connected to the inner wall of the storage bin 2. The sealing baffles 31 can cooperate with the box seat 3 to block the top of the storage bin 2. Air inlet openings 13 communicating with the inside thereof are evenly distributed at the bottom of the drone fuselage shell 1. A flow blocking platform 14 is provided at the position corresponding to the air inlet openings 13 at the bottom of the drone fuselage shell 1. The flow blocking platform 14 can provide flow blocking and waterproof protection for the air inlet openings 13. A filter screen is further arranged in the air inlet openings 13 to prevent dust from entering and causing pollution.

[0039] When the heat dissipation fan 33 is working, it sucks and discharges the air and heat in the box seat 3 to the outside to achieve heat dissipation in the box seat 3. As Figure 10 shown, the external air is sucked into the drone fuselage shell 1 from the air inlet openings 13 at the bottom of the drone fuselage shell 1, and flows into the box seat 3 through the diversion openings 21 and the diversion holes 32 in sequence for air flow replenishment, thereby forming a continuous heat dissipation flowing air current. When the air current flows through the inside of the drone fuselage shell 1, it can absorb and dissipate the heat inside the drone fuselage shell 1. The heat conducting fins 22 can transfer the heat near the heat source inside the drone fuselage shell 1 to the inside of the box seat 3 for heat dissipation. Figure 10 In the figure, the solid arrow is the movement direction of the heat dissipation air current, and the dotted arrow is the schematic diagram of the heat conduction flow direction of the heat conducting fins 22. Furthermore, a shared heat dissipation flow channel and structure can be formed inside the drone fuselage shell 1, the storage bin 2 and the box seat 3, which can not only dissipate heat in the box seat 3, but also dissipate heat inside the drone fuselage shell 1, effectively improving the heat dissipation effect of the drone.

[0040] In addition, as Figure 9 shown, an installation opening 11 for installing the storage bin 2 is provided at the top of the drone fuselage shell 1. Clamping plates 12 are respectively arranged on both sides of the air inlet openings 13 inside the drone fuselage shell 1. A clamping opening 121 is formed between the two clamping plates 12. The base seat 201 at the bottom of the storage bin 2 is correspondingly and tightly installed in the clamping opening 121 to ensure that the installation of the box seat 3 is firm and stable enough. The bottom of the base seat 201 and the bottoms of the two clamping plates 12 together form a guiding surface 01 for guiding the air current entering the drone fuselage shell 1 from the air inlet openings 13 to both sides.

[0041] As Figure 10As shown, the base 201 at the bottom of the storage bin 2 and the two clamping plates 12 form a guiding surface 01, which can block the airflow entering the drone fuselage shell 1 from the air inlet 13 and divert it to both sides, so that the air bypasses the clamping plates 12 on both sides and then enters the storage bin 2. Furthermore, the flow range of the cooling airflow in the drone fuselage shell 1 is expanded, ensuring a larger coverage area of the cooling airflow and further improving the cooling effect on the inside of the drone fuselage shell 1. Secondly, the base 201 and the clamping plates 12 serve both as the installation parts of the storage bin 2 and as the guiding parts of the cooling airflow, killing two birds with one stone.

[0042] As Figure 6 shown, the second driving mechanism 6 includes a bidirectional screw 61, nut seats 62, racks 63, a second driving motor 64 and gears 65. Side grooves 41 are respectively provided on both sides of the top cover seat 4, and a sliding groove 42 communicating with both side grooves 41 is provided inside the top cover seat 4. Shaft rods 43 are rotatably installed in both side grooves 41, and first connection seats 44 are fixed on both shaft rods 43. Two mounting brackets 7 are respectively fixed on the corresponding first connection seats 44. The bidirectional screw 61 is rotatably installed in the sliding groove 42. The second driving motor 64 is fixed on one side of the top cover seat 4, and the output shaft is fixedly connected to one end of the bidirectional screw 61. Two nut seats 62 are respectively installed in the sliding groove 42 in a limited sliding manner and are sleeved on both sides of the bidirectional screw 61 in a thread-matching manner. Racks 63 are fixed to the bottoms of both nut seats 62, and gears 65 are fixedly sleeved on both shaft rods 43. The gears 65 are meshed with the corresponding racks 63.

[0043] By the operation of the second driving motor 64, its output shaft drives the bidirectional screw 61 to rotate. The rotating bidirectional screw 61 thread-drives the two nut seats 62 to approach or move away from each other, thereby driving the racks 63 to reciprocate. The reciprocating racks 63 can meshingly drive the gears 65 and drive the shaft rods 43 to rotate, and then the mounting brackets 7 can be driven to rotate and adjust, providing an effective drive for the angle adjustment, unfolding and storage of the mounting brackets 7.

[0044] In addition, the method of using the bidirectional screw 61 to thread-drive the nut seat 62 to move has a self-locking effect. When the second driving motor 64 is not working, it prevents the mounting bracket 7 from swinging randomly, helps to maintain the angle of the mounting bracket 7, has strong wind resistance and high stability. At the same time, it also prevents the output shaft of the second driving motor 64 from being overloaded when it is not working, ensuring a longer service life of the second driving motor 64.
