[0002] Drones play a vital role in military, public security, commerce, environmental protection, and other fields. However, battery life is the primary technical bottleneck restricting their application. Currently, most drones have a flight time of between 30 minutes and one hour, which limits their range. Frequent charging also increases operational time and risks.

[0003] A solar cell is a device that converts solar energy into electricity using the photovoltaic effect. Thin-film solar cells offer advantages such as low mass, extreme thinness, flexibility, and simple manufacturing. Currently, cadmium telluride thin-film solar cells, copper indium gallium selenide thin-film solar cells, and amorphous silicon thin-film solar cells have all been commercialized.

[0004] Currently, solar cells are usually laid flat on drones for use. The application of solar cells to drones is limited by the size of the drone and the energy conversion rate of the solar cells. Very large wings are required to achieve relatively considerable energy conversion. However, drones are usually small in size, resulting in low solar energy conversion efficiency and low flexibility of use. Summary of the Invention

[0030] Embodiment 1

[0031] This embodiment provides a foldable solar charging component. Please refer to Figure 1 and Figure 2, including a solar cell 1, a driving component 3 and a control component 4; the solar cell 1 is used to be connected to the storage bin 21 of the fuselage 2; the driving component 3 is connected to the solar cell 1, and the driving component 3 can drive the solar cell 1 to extend out of the storage bin 21 and unfold so as to be able to perform photovoltaic power generation, and the driving component 3 can also drive the solar cell 1 to be stored in the storage bin 21; the control component 4 is communicatively connected to the driving component 3 and can control the action of the driving component 3; the control component 4 is also communicatively connected to the solar cell 1 and can regulate the electric energy of the solar cell 1.

[0032] The working principle is as follows: Under the control of the control component 4, the driving component 3 is used to control the solar cell 1 to unfold or be stored in the storage bin 21 provided on the fuselage 2. When the drone is in the charging state, the driving component 3 drives the solar cell 1 to extend out of the storage bin 21 and unfold so as to be able to perform photovoltaic power generation. When charging is not required, the driving component 3 drives the solar cell 1 to be stored in the storage bin 21, which can also play a role in protecting the solar cell 1; By setting it in the form of a solar charging component that can be stored, compared with the solar cell directly laid flat on a small-sized drone, it is convenient to accommodate a large-sized solar cell in a small space. After unfolding, the large-sized solar cell greatly shortens the energy conversion time, realizes the purpose of long-distance flight of the drone, and expands the usage scenarios of the drone.

[0033] In an alternative embodiment of the present embodiment, preferably, the solar cell 1 is set as a thin-film solar cell, and the thin-film solar cell has advantages such as small mass, extremely thin thickness, bendability, and simple manufacturing process, which is convenient for realizing the unfolding and storage of large sizes.

[0034] In an alternative embodiment of the present embodiment, preferably, the driving component 3 includes a temperature control component 31 and a shape memory element 32. Both the temperature control component 31 and the shape memory element 32 are connected to the solar cell 1. The temperature control component 31 is communicatively connected to the control component 4, and the control component 4 controls the temperature control component 31 to heat or cool the shape memory element 32 so that the shape memory element 32 deforms, so as to drive the solar cell 1 to extend out of the storage bin 21 and unfold, or drive the solar cell 1 to be stored in the storage bin 21.

[0035] Specifically, by utilizing the characteristic that the shape memory element 32 can actively change its shape or restore its preset shape under external stimuli such as temperature, under the temperature control of the temperature control component 31, the repeated shape memory effect of the shape memory element 32 is realized, thereby driving the unfolding or storage of the solar cell 1.

[0036] In an alternative embodiment of the present embodiment, preferably, the driving component 3 further includes a temperature monitoring element 33 communicatively connected to the control component 4, which is arranged on the shape memory element 32 and is used to monitor the temperature of the shape memory element 32; the control component 4 can receive the monitoring information of the temperature monitoring element 33.

[0037] Among them, by setting the temperature monitoring member 33, it is convenient to obtain the temperature of the shape memory member 32 in a timely manner, so as to master the deformation information of the shape memory member 32 and judge whether it is in the deployed or stored state.

[0038] In an alternative embodiment of the present embodiment, preferably, one end of the solar cell 1 is fixedly connected to a fixed shaft 5, and the fixed shaft 5 is fixedly arranged in the storage bin 21. The two ends of the fixed shaft 5 can be fixedly connected to the inner wall of the storage bin 21 by welding or bonding. One end of the solar cell 1 can be bonded to the fixed shaft 5. By arranging the fixed shaft 5, it is convenient for the solar cell 1 to be wound around the fixed shaft 5 in the stored state; on the other two opposite side ends of the solar cell 1, shape memory members 32 are fixedly arranged along the length direction. The shape memory members 32 on both sides can achieve shape changes of curling and planar unfolding at different temperatures, so as to drive the solar cell 1 to realize the state switching between curling storage and planar unfolding; temperature control components 31 are fixedly arranged along the length direction on each shape memory member 32, so as to realize temperature control of the entire shape memory member 32 in the length direction and improve the deformation efficiency.

[0039] Among them, the shape memory member 32 is fixedly connected to the solar cell 1 through an adhesive, and the temperature control component 31 is heat-conductively and fixedly connected to the shape memory member 32 through a heat-conductive adhesive; the temperature control component 31 can regulate the temperature of the shape memory member 32 and cause the shape memory member 32 to deform, so as to drive the solar cell 1 to extend out of the storage bin 21 and unfold, or drive the solar cell 1 to be wound around the fixed shaft 5 for storage in the storage bin 21.

[0040] Further preferably, a fixed rod 6 can be fixedly arranged at one end of the solar cell 1 away from the fixed shaft 5. Among them, one end of the shape memory member 32 can also be connected to the fixed rod 6 to improve the stability of the end part.

[0041] In an alternative embodiment of the present embodiment, preferably, a plurality of temperature monitoring members 33 are arranged along the length direction on each shape memory member 32; by arranging a plurality of temperature monitoring members 33, it is convenient to comprehensively monitor the temperature of the shape memory member 32. The temperature monitoring member 33 can be set as a flexible thin-film temperature sensor and is attached to the surface of the shape memory member 32 for temperature monitoring.

[0042] In an alternative embodiment of the present embodiment, preferably, each shape memory member 32 is set as a shape memory alloy, and each temperature control component 31 is set as a heating component. The heating component can heat the shape memory member 32 to cause the shape memory member 32 to deform, so as to drive a plurality of solar cells 1 to extend out of the storage bin 21 and unfold; each shape memory member 32 can naturally cool and deform to drive the solar cell 1 to be stored in the storage bin 21.

By thermally controlling the phase transformation shape of the alloy, repeated shape memory effects can be achieved; the heating component can be set as a heating resistance wire. The temperature monitoring component 33 monitors the temperature parameters of the shape memory alloy in real time and feeds them back to the control component 4. The heating component can accurately control the heating temperature of the shape memory component 32 to the phase transformation temperature, drive the solar thin-film battery to fully unfold, and maximize the light energy reception; when charging stops, the control component 4 turns off the heating device, and the shape memory alloy naturally cools to the martensite phase, restoring flexibility, driving the solar thin-film battery to contract and stop receiving light energy.

[0045] Such as Figure 5 As shown in the control principle of the control component 4, the control component 4 includes a solar charging controller 41 and a storage battery 42 disposed in the fuselage 2. The control component 4 can be integrally set with the controller of the unmanned aerial vehicle. During charging, the temperature control component 31 is started under the action of the temperature control circuit 43 of the control component 4. The temperature of the shape memory alloy rises and causes deformation. The solar thin-film battery unfolds to receive sunlight, converts light energy into direct current electrical energy. The solar charging controller 41 optimizes the electrical energy output, manages the electrical energy storage, and the optimized electrical energy is stored in the storage battery 42 through the charging circuit; the storage battery 42 supplies power to the load 7 of the unmanned aerial vehicle to realize the normal operation of each component of the unmanned aerial vehicle; the temperature monitoring component 33 monitors the temperature parameters of the shape memory alloy in real time and feeds them back to the temperature control circuit 43 to accurately control the temperature of the shape memory alloy to the phase transformation temperature, and the solar thin-film battery fully unfolds to maximize the light energy reception; when charging stops, the temperature control circuit 43 receives the contraction command signal of the control component 4, turns off the temperature control component 31, the shape memory alloy cools to the martensite phase, restores flexibility, the solar thin-film battery contracts, and stops receiving light energy.

[0049] Among them, the adjacent sub-cells 11 and the inner sub-cells 11 and the inner wall of the storage bin 21 are connected by shape memory elements 32, so that the shape memory elements 32 can unfold after being heated and deformed, so as to drive the connected sub-cells 11 to be unfolded passively, and can recover to the initial shape after the shape memory elements 32 are cooled, so as to drive the connected sub-cells 11 to approach and fold passively, realizing the state switching between the folding storage and the planar unfolding of the solar cell 1; it should be noted that the heating deformation driving directions of the shape memory elements 32 connected to both ends of each sub-cell 11 should make the adjacent sub-cells 11 have the same movement tendency, that is, move away from each other to unfold; on the contrary, the cooling deformation driving directions of the shape memory elements 32 connected to both ends of each sub-cell 11 should make the adjacent sub-cells 11 have the same movement tendency, that is, move closer to each other to fold and store.

[0050] In an alternative solution of this embodiment, preferably, frames 12 are fixedly arranged on the peripheries of the sub-cells 11, and the adjacent frames 12 are connected by shape memory elements 32; and reinforcing parts 13 are arranged on each frame 12; by arranging the frames 12, the overall stability is improved, and at the same time, the cooperative connection between the adjacent sub-cells 11 is facilitated; the reinforcing parts 13 can be arranged as reinforcing ribs and are arranged on the backlight side of the frames 12 to improve the overall strength.

[0056] A plurality of storage compartments 21 can be provided on the fuselage 2 as needed, and a plurality of retractable solar charging components are correspondingly provided, which is convenient for accommodating large-sized solar cells in a small space. After being unfolded, the large-sized solar cells can greatly shorten the energy conversion time, achieve the purpose of long-distance flight of the drone, and expand the usage scenarios of the drone. In addition, by providing the hatch 22 to close the storage compartment 21 in the storage state, a protective effect is achieved.

[0057] Further preferably, the hatch 22 can be electrically controlled to open and close through an electric telescopic rod. When solar power generation is required, the control component 4 controls the electric telescopic rod to open the hatch 22 so that the solar cell can extend out of the storage compartment 21. After the solar cell is stored in the storage compartment 21, the control component 4 controls the electric telescopic rod to close the hatch 22. Among them, the hatch 22 should be placed on the backlight side of the solar cell to avoid the hatch 22 affecting the power generation of the solar cell. [[ID=^]]
