[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, the present invention provides a portable integrated device for thermal repair of composite materials for unmanned aerial vehicles, comprising a box body 1 and a box cover 2, and also comprising:

[0033] A telescopic component, which is arranged on the box 1 and is used to control the height of the composite material thermal patching instrument;

[0034] A storage structure, which is arranged on the box cover 2 and is used to store repair accessories;

[0035] Among them, the telescopic component includes a first fixed shaft 3, which is fixed to the inner wall of the box body 1, and the outer surface of the first fixed shaft 3 is sleeved with a protective shell 4 and a second spring 17, and the middle part of the protective shell 4 is sleeved with a composite material hot repair instrument body 5, and notches 23 are provided on both sides of the box body 1, and a slide rail 6 is fixed on the inner wall of the notch 23, and movable parts 7 are connected to both sides of the protective shell 4, and a slide groove 8 is provided on one side of the movable part 7, and a movable rod 9 is slidably connected to the inner wall of the slide groove 8, and a movable frame 10 is rotatably connected to the outer side of the movable rod 9, and a cavity 11 is provided on the inner side of the box body 1, and a second fixed shaft 12 is fixed inside the cavity 11, and the outer surface of the second fixed shaft 12 is sleeved with a first spring 13 and a movable plate 14, and a button 15 is fixed on the upper side of the movable plate 14, and a limit member 16 is fixed on the lower side of the movable plate 14;

[0036] Among them, the storage structure includes a storage bag 18, the storage bag 18 is fixed on the inner wall of the box cover 2, the outer side of the storage bag 18 is connected to a baffle 19, a layer of the baffle 19 is fixed with a Velcro hook surface 20, the inner wall of the box cover 2 is fixed with a Velcro fur surface 21, and the inner side of the box cover 2 is hinged with a support frame 22 through a torsion spring.

[0037] The storage bag 18 can be used to store repair accessories, and the cooperation between the Velcro hook surface 20 and the Velcro fleece surface 21 can cover the repair accessories inside the storage bag 18. When the limiter 16 is separated from the movable part 7, the protective shell 4 and the movable part 7 will be driven to move downward under the influence of the gravity of the composite material heat repair instrument body 5. At this time, the movable rod 9 can be driven by the slide groove 8 to pull the movable frame 10, and the box cover 2 can be driven to rotate downward through the movable frame 10, and the composite material heat repair instrument body 5 can be moved downward through the composite material heat repair instrument body 5, so that the top of the box body 1 has additional accommodating space to avoid squeezing of the storage bag 18 and the composite material heat repair instrument body 5. At the same time, the box cover 2 and the box body 1 are closed and locked for easy carrying.

[0038] like Figure 1 , 2 As shown, the composite material thermal repair instrument body 5 includes a control console 51 , the top surface of which is provided with a controller 52 , a heating accessory interface 53 and a vacuum exhaust interface 54 , and the control console 51 is sleeved on the inner wall of the protective shell 4 .

[0039] The console 51 is powered on and connected to a hot air gun through the heating accessory interface 53 to preheat it to an appropriate temperature. The repaired part of the drone is then cleaned. A negative pressure tool is connected through the vacuum exhaust interface 54 to insulate it. A highly purified thermosetting resin is filled on its surface and heated and softened with a hot air gun. After the material softens, it is polished with sandpaper or other tools.

[0040] like Figure 1As shown, the box body 1 and the box cover 2 are hinged, and the box cover 2 and the box body 1 are connected by a lock, and a handle is rotatably connected to one side of the box body 1.

[0041] Through the cooperation between the box body 1 and the box cover 2, the box cover 2 can be rotated along the top of the box body 1, so that the composite material heat repair instrument body 5 inside the box body 1 and the accessories inside the storage bag 18 can be stored, thereby facilitating their unified carrying.

[0042] like Figure 2 , 3 As shown, the second spring 17 is elastically supported between the protective shell 4 and the box body 1 , and the elastic force of the second spring 17 is smaller than the gravity of the console 51 .

[0043] The second spring 17 is designed to support the protective shell 4, thereby slowing down the descending speed of the composite material thermal repair instrument body 5, avoiding collision when the composite material thermal repair instrument body 5 descends, and preventing damage to the composite material thermal repair instrument body 5.

[0044] like Figure 1 , 5 As shown, the top of the movable frame 10 is hinged to the box cover 2. When the box cover 2 rotates upward, the movable frame 10 drives the movable part 7 to move upward through the movable rod 9. When the protective shell 4 is blocked by the box body 1, the top surface of the console 51 is flush with the top surface of the box body 1.

[0045] Through the cooperation between the movable frame 10 and the box cover 2, when the box cover 2 is opened, the box cover 2 will rotate upward and apply a pulling force to the movable frame 10, so that the movable frame 10 can drive the movable rod 9 to drive the movable part 7 to move the protective shell 4 upward, so that the composite material thermal repair instrument body 5 can be driven by the protective shell 4 to move to the top surface of the box body 1, which is convenient for the user's operation.

[0046] like Figure 5 As shown, the lower end of the limiting member 16 is provided with a chamfer, the movable member 7 is in extrusion contact with the chamfer of the limiting member 16 , and the protective shell 4 is slidably connected with the slide rail 6 .

[0047] By setting the chamfer at the lower end of the limiting member 16, when the movable member 7 presses the limiting member 16, the movable plate 14 will be driven by the limiting member 16 to move along the outer surface of the second fixed shaft 12, so as to avoid the limiting member 16 blocking the movable member 7 moving upward.

[0048] like Figure 5 As shown, the first spring 13 is elastically supported between the cavity 11 and the movable plate 14 , and when the movable member 7 is located above the limiting member 16 , the top surface of the limiting member 16 blocks the bottom surface of the movable member 7 .

[0049] Through the design of the first spring 13, the movable plate 14 has good elastic reset performance. At this time, since the first spring 13 is in a compressed state, an elastic force will be applied to the movable plate 14, so that the limit member 16 can be driven to move outward through the movable plate 14, so that the limit member 16 can block the movable member 7 and limit it to make it more stable.

[0050] like Figure 6 As shown, the support frame 22 is in compression contact with the baffle 19, and the longitudinal section of the storage bag 18 is fan-shaped, and both sides thereof are corrugated.

[0051] Through the cooperation between the support frame 22 and the baffle 19, under the action of the torsion spring, the support frame 22 can drive the baffle 19 to move and unfold the storage bag 18, so as to facilitate the removal or placement of accessories. Moreover, since the two sides of the storage bag 18 are corrugated, it is convenient to fold it and reduce the space it occupies.

[0052] like Figure 1 As shown, the storage bag 18 contains repair accessories inside, and the Velcro hook surface 20 is bonded to the Velcro fleece surface 21 .

[0053] Through the cooperation between the Velcro hook surface 20 and the Velcro fleece surface 21, when the Velcro hook surface 20 and the Velcro fleece surface 21 are bonded, the storage bag 18 can be folded, and at the same time, the accessories inside the storage bag 18 can be protected to prevent them from falling off.

[0054] Working principle:

[0055] First, the user can open the lock between the box cover 2 and the box body 1, and open the box cover 2 and the box body 1. At this time, the box cover 2 will rotate upward, and the movable frame 10 will drive the movable rod 9 to move upward, so that it applies a pulling force to the slide groove 8, and the movable part 7 will drive the protective shell 4 to slide along the inner side of the slide rail 6. The slide rail 6 can reduce the friction force of the protective shell 4 when it moves, and the elastic force of the second spring 17 can support the protective shell 4, so that the composite material heat repair instrument body 5 can save the force required for the composite material heat repair instrument body 5 to move upward. After the box cover 2 is opened, the elastic force of the first spring 13 can drive the limit member 16 to block the bottom surface of the movable part 7 through the movable plate 14, so as to prevent the protective shell 4 and the composite material heat repair instrument body 5 from being moved upward. The main body 5 of the composite material hot repair instrument falls off, and then the user pulls the Velcro hook surface 20 to separate the Velcro fleece surface 21. At this time, the support frame 22, under the action of the torsion spring, will push the baffle 19 to rotate outward and open the storage bag 18, so as to facilitate the removal of the accessories inside the storage bag 18. The control console 51 is powered on, and a hot air gun is connected to it through the heating accessory interface 53 to preheat it to an appropriate temperature. Then, the repair part of the drone is cleaned and filled with highly purified thermosetting resin on its surface. At the same time, the vacuum exhaust interface 54 is used to connect a negative pressure tool to insulate the repair part of the drone, and it is heated and softened with a hot air gun. After the material is softened, it is polished with sandpaper or other tools.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
