[0030] The utility model will be further described in detail in combination with the drawings.

[0031] The most optimal embodiment: a long-endurance power unmanned aerial vehicle device, see Figures 1-4 , including the body in the middle, the body around the horizontal extension of the arm, the arm end of the rotor mechanism 1, the body is installed on the battery (not shown in the figure), the battery and the rotor mechanism 1 are connected and powered, the body is also installed on the charging device, the charging device includes a wrapped solar film battery 2 and a battery telescopic control device connected with the solar film battery 2, the power output end of the solar film battery 2 is connected with the battery to form a charging loop.

[0032] In this way, the unmanned aerial vehicle device uses the battery power to rely on the battery telescopic control device to control the wrapped solar film battery to extend outward and unfold, receive sunlight to charge the battery, so that the battery area is not limited by the volume of the unmanned aerial vehicle, which can better improve the endurance of the unmanned aerial vehicle. When there is no need to charge, the solar film battery can be wrapped back, so that it does not interfere with the normal flight of the unmanned aerial vehicle. Therefore, the device utilizes the characteristics of flexible, light weight and telescopic of the thin film solar cell to realize the control of the battery, which improves the charging efficiency and endurance of the unmanned aerial vehicle, reduces the flight interference of the unmanned aerial vehicle, and ensures the stability of the unmanned aerial vehicle.

[0033] Among them, the arm includes a hollow connection arm 3 and an arm decoration 4 covering the outer surface of the connection arm.

[0034] In this way, the connection arm is made of hollow material, which cooperates with the decoration on the outer surface to improve the appearance while ensuring sufficient strength and low weight.

[0035] Among them, the body includes a base 5 and a decorative cover 6 installed on the upper surface of the base 5, the inner end of the connection arm 3 is fixed on the base 5, and the arm decoration 4 is inlaid with the edge of the decorative cover 6.

[0036] In this way, better protection effect and improved appearance are achieved.

[0037] Among them, the charging device is installed between the base 5 and the decorative cover 6, the side of the decorative cover 6 is provided with a battery outlet, and the battery telescopic control device can control the solar film battery 2 to extend and unfold along the battery outlet.

[0038] In this way, the charging device is better protected.

[0039] Among them, the solar film battery 2 is symmetrically arranged in pairs along the center of the body.

[0040] In this way, the solar film battery is unfolded in pairs along the center of the body to the two sides, which better maintains the balance and stability of the unmanned aerial vehicle.

[0041] The battery telescopic control device comprises a pair of battery rotating shafts 7, which are symmetrically arranged on the base 5, and the solar thin film batteries 2 are wrapped around the corresponding battery rotating shafts 7. A telescopic mechanism is arranged below each solar thin film battery. The battery telescopic control device further comprises a control motor and a linkage transmission mechanism connected with the control motor. The linkage transmission mechanism is connected between the battery rotating shafts and the corresponding telescopic mechanisms. The fixed end of the telescopic mechanism is arranged on the base, and the telescoping end of the telescopic mechanism is horizontally arranged outside and connected with the outer end of the solar thin film battery 2.

[0042] Thus, when charging is needed, the control motor is positively rotated to drive the telescopic mechanism to extend outward and synchronously rotate the battery rotating shafts, so that the solar thin film batteries can synchronously extend outward and horizontally expand to absorb sunlight for charging. After charging is completed, the control motor is reversely rotated to drive the telescopic mechanism to retract and reversely rotate the battery rotating shafts to synchronously wrap the solar thin film batteries. Therefore, the synchronous linkage is convenient, the expansion and retraction of the solar thin film batteries are synchronously controlled, the structure is simple, compact, ingenious and stable.

[0043] The linkage transmission mechanism comprises a pair of linkage gears 8 arranged at the same end of each pair of battery rotating shafts. The linkage gears 8 are arranged in meshing relationship with each other. The linkage transmission mechanism further comprises a middle shaft 9 arranged in parallel between the two battery rotating shafts 7. The end of the middle shaft 9 facing the linkage gears is connected with any battery rotating shaft through a transversely arranged belt mechanism 10. The end of the middle shaft 9 away from the linkage gears is provided with a driving bevel gear 11. The driving bevel gear 11 is in meshing relationship with a driven bevel gear 12 arranged on each side of the driving bevel gear 11. A screw rod 13 is arranged at the shaft center of each driven bevel gear 12. The screw rod 13 is rotatably arranged on the base through a screw rod seat. The screw rod 13 is provided with a boss on both sides of the screw rod seat to limit the axial movement of the screw rod 13. An outer end of the screw rod 13 is rotatably connected with a nut 14 arranged below the corresponding battery rotating shaft. A rotation limiting structure is arranged between the nut 14 and the base 5. The nut is connected with the telescopic mechanism.

[0044] Thus, the screw rod and the nut constitute a screw-nut transmission mechanism. After the control motor is transmitted to the linkage transmission mechanism, the two linkage gears can drive the two battery shafts to rotate reversely. At the same time, the battery shafts drive the intermediate shaft to rotate in the same direction through the belt mechanism, and then drive the two screw rods on the two sides to rotate through the bevel gears, and then drive the nut to translate axially through the screw-nut transmission mechanism, and then drive the telescopic mechanism to extend outward, so as to realize the synchronous linkage control of the telescopic mechanism and the battery shafts, and then stably and reliably drive the solar thin-film batteries to extend outward and retract. The structure is simple, and the transmission is stable and reliable. In implementation, the rotation-stopping limiting structure can be a limiting surface which is attached to at least one surface of the nut to stop rotation.

[0045] The one end of any battery shaft is a power input end 15 and is connected with the control motor (not shown in the figure) in transmission. In this way, the power input is facilitated.

[0046] The telescopic mechanism comprises a plurality of pairs of hinged rods 16 which are hinged in X shape. The ends of each pair of hinged rods 16 are hingedly connected with the ends of the adjacent pair of hinged rods, so that the pairs of hinged rods are arranged in a straight line shape. The outer ends 19 of the outermost pair of hinged rods are hingedly fixed to the lower surfaces of the corresponding solar thin-film batteries. The hinge shafts 20 at the hinged points of the innermost pair of hinged rods are installed and positioned on the base. The two feet at the inner ends of the innermost pair of hinged rods are provided with sliding grooves 17 along the length direction of the hinged rods. The telescopic mechanism further comprises two push rods 18 which are parallel to each other and arranged along the arrangement direction of the hinged rods. One end of the push rod 18 is fixed to the nut 14, and the other end is provided with a circular hinged joint along the side surface and is slidably clamped in the sliding groove 17.

[0047] In the process of driving the nut to translate axially through the screw-nut transmission mechanism, the two push rods can be controlled to extend outward or retract inward, so as to drive the two hinged rods at the starting end to rotate relative to each other to open or fold. The linkage of the hinged rods realizes the rapid extension and retraction of the solar thin-film batteries. Therefore, the telescopic mechanism only needs to control the rotation of the single pair of hinged rods at the starting end by a short distance, so as to drive the entire telescopic mechanism and the batteries to realize the rapid extension and retraction by a long distance. The structure is simple, the transmission is stable, the control distance is long, and the reaction is fast.
