specific Embodiment approach 1

[0032] Specific implementation mode one: combine Figure 1 to Figure 11 Describe this embodiment, a passive wing telescopic structure described in this embodiment includes a wing 1, a telescopic wing 2, a linkage rope 7, a traction mechanism and a resettable telescopic mechanism, and the middle part of the front end of the wing 1 is provided with a slot. The end of the telescopic wing 2 is inserted into the slot, the telescopic wing 2 is connected to the wing 1 through a resettable telescopic mechanism, one end of the linkage rope 7 is fixedly connected to the end of the telescopic wing 2, and the other end of the linkage rope 7 passes through the slot Connect with the control mechanism that is positioned at fuselage behind the groove bottom, linkage rope 7 controls telescopic wing 2 telescopic by traction mechanism.

[0033] The interlocking rope 7 is used to lock the movement of the resettable telescopic mechanism and the traction mechanism, and the telescopic movement of th...

specific Embodiment approach 2

[0037] Specific implementation mode two: combination Figure 1 to Figure 11 Describe this embodiment, the resettable telescopic mechanism described in this embodiment includes an elastic member 5, a fixed rod 6 and a sliding rod 8, one end of the fixed rod 6 is fixedly connected to the groove bottom of the slot of the wing 1, and the other end of the fixed rod 6 Inserted in one end of the sliding rod 8, an elastic member 5 is provided between one end of the sliding rod 8 and the groove bottom of the slot, and the other end of the sliding rod 8 extends to the inside of the telescopic wing 2. Other compositions and connection methods are the same as those in Embodiment 1.

[0038] The resettable telescopic mechanism designed in this way utilizes the moving principle of the movable pulley, and the elastic member 5 is from Figure 6 The compressed state shown in stretches to figure 2 In the stretched state shown in , the stretched length is about half of the compressed length, ...

Abstract

The invention discloses a passive wing telescopic structure, and relates to the technical field of aviation aircraft design. The problems that an existing unmanned aerial vehicle is large in wingspan, large in occupied space, high in maintenance cost and large in probability of being detected and found are solved. The unmanned aerial vehicle comprises a wing, a telescopic wing, a linkage rope, a traction mechanism and a resettable telescopic mechanism, a slot is formed in the middle of the front end face of the wing, the tail end of the telescopic wing is inserted into the slot, the telescopic wing is connected with the wing through the resettable telescopic mechanism, one end of the linkage rope is fixedly connected with the tail end of the telescopic wing, the other end of the linkage rope penetrates through the groove bottom of the inserting groove and then is connected with a control mechanism located on the fuselage, and the linkage rope controls the telescopic wings to stretch out and draw back through a traction mechanism. According to the working principle of the movable pulley, the compression spring is adopted as a driving part, the compression stroke of the elastic part is shortened, the machining difficulty of the elastic part is reduced, other power sources are not needed, the influence of high altitude and low temperature is avoided, and the system can be applied to different unmanned aerial vehicles as an independent system.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to a passive wing telescopic structure. Background technique [0002] The characteristic of high-altitude and long-endurance UAV is that it can carry out long-term reconnaissance missions at high altitude. long wingspan. The wingspan is too long, which leads to the high-altitude and long-endurance drones taking up a lot of space during transportation and storage, which not only increases the difficulty of ground maintenance and transportation, but also increases maintenance costs in disguise, and is also very easy to use during transportation and storage. Was detected to miss the fighter plane. [0003] In order to solve this problem, when large-wing-span drones are stored and transported, it is usually used to change the length of the wings or fold the deformation to reduce the space occupied by the drone. Considering the reliability and convenience of the system, The de...
