[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Various non-limiting embodiments of the present invention are described below. The numbers of any elements in the accompanying drawings are for illustrative purposes only and are not intended to be limiting, and any nomenclature is for distinction only and does not have any limiting meaning. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other unless there is a conflict.

[0027] Example 1 of the pusher like Figure 1 As shown, a pushing member for a fixed reset device of a drone nest, the pushing member 3 is located on the apron 2 of the nest 1.

[0028] Specifically, the pushing member 3 includes a linear drive assembly, a front end fixing portion and two rear end fixing portions, and the front end fixing portion and the two rear end fixing portions can be driven by the linear drive assembly to move in a straight line on the apron 2. There are two linear drive assemblies, which are located on both sides of the apron 2. The linear drive assembly in this embodiment can be a screw nut pair.

[0029] In other embodiments, the linear drive assembly may be a cylinder assembly, a hydraulic cylinder assembly, or an electric push rod assembly.

[0030] like Figure 10 、 Figure 11As shown, the drone 16 mentioned in this embodiment is a multi-rotor drone disclosed in Chinese patent application CN220865682U. This is prior art and therefore will not be described in detail in this embodiment. The drone nest 1 mentioned in this embodiment is used to dock the multi-rotor drone disclosed in the aforementioned patent application. The drone nest 1 is capable of storing the drone 16.

[0031] Drone 16 is positioned between the front and rear mounting sections. The front mounting section and two rear mounting sections secure drone 16. The two rear mounting sections are connected to the front mounting section, forming a V-shaped structure. When drone 16 is secured, it sits inside the V-shaped structure. The front mounting section engages with the front legs 17 of drone 16 to secure the front of drone 16, while the rear mounting section engages with the rear legs 18 of drone 16 to secure the rear of drone 16.

[0032] like Figure 2-Figure 5 As shown, each rear end fixing portion includes a first mounting seat 8, and each first mounting seat 8 is provided with a driving member 5 and a hook 4 that rotates around an axis extending up and down. The hooks 4 on the two first mounting seats 8 are arranged relative to each other, so that the corresponding driving member 5 can drive the corresponding hook 4 to hook the rear tripod 18 of the drone 16 from the opposite sides respectively, so as to achieve the fixation of the rear side of the drone 16. This fixing method can make the fixation of the drone 16 more stable.

[0033] When the drone 16 lands on the landing pad 2, the front fixing portion blocks the front leg 17 of the drone 16, and the rear fixing portion hooks the rear leg 18 of the drone 16, thereby respectively securing the front and rear sides of the drone 16, thereby securing the entire drone 16. When the drone 16 is to be used, the driving member 5 is simply controlled to drive the hook 4 to separate from the rear leg 18 of the drone 16, and the drone 16 can directly take off vertically in the vertical direction, thus realizing the quick removal and use of the drone 16.

[0034] like Figure 3 、 Figure 9 As shown, each first mounting base 8 is provided with a switch trigger 6, which is electrically connected to a controller 23, which is electrically connected to a driver 5. A signal generated by the triggering of the switch trigger 6 is transmitted to the controller 23, which controls the operation of the driver 5. When the rear leg 18 of the drone 16 contacts the switch trigger 6, triggering the switch trigger 6, the controller 23 controls the corresponding driver 5 to drive the hook 4 to hook the rear leg 18 of the drone 16, thereby securing the rear side of the drone 16.

[0035] When it is necessary to recover the drone 16, the drone 16 will land at the device, and the front leg 17 of the drone 16 will contact the front fixing part, and the rear leg 18 of the drone 16 will contact the rear fixing part. The order of contact is not fixed, and it can be either one in front or the other, or at the same time. After the drone 16 lands in place, the rear leg 18 of the drone 16 will touch the switch trigger 6, and the switch trigger 6 will transmit a signal to the controller 23. The controller 23 controls the driving member 5 to drive the hook 4 to hook the rear leg 18 of the drone 16, thereby fixing the rear side of the drone 16. When it is necessary to release the drone 16, the controller 23 will control the driving member 5 to drive the hook 4 to separate from the rear leg 18 of the drone 16, and no longer fix the rear side of the drone 16. After that, the drone 16 can take off.

[0036] The first mounting base 8 is provided with a rear leg mounting slot 9 for engaging with the rear leg 18 of the drone 16. A hook 4 engages the rear leg 18 of the drone 16 and secures it within the rear leg mounting slot 9. A switch trigger 6 is mounted within the rear leg mounting slot 9. When the rear leg 18 of the drone 16 moves into the rear leg mounting slot 9, it contacts the switch trigger 6, indicating that the drone 16 has moved into position. The hook 4 then engages the rear leg 18, securing the rear of the drone 16. The rear leg mounting slot 9 has a first stop surface extending vertically and designed to engage with the front of the rear leg 18 of the drone 16. The switch trigger 6 is also located on the first stop surface. The hook 4 has a second stop surface extending vertically, oriented oppositely from the first stop surface, and capable of engaging with the rear side of the rear leg 18 of the drone 16. The rear side of the drone 16 is fixed by the first stopping surface of the rear foot mounting groove 9 and the second stopping surface of the hook 4 stopping the rear leg 18 of the drone 16 .

[0037] In this embodiment, the output end of the driver 5 is secured to a rotating member 12, which rotates about the output end of the driver 5. Rotating member 12 is spherically hinged to a transmission rod 7, which in turn spherically hinges with hook 4. Operation of the driver 5 causes rotating member 12 to rotate. The spherical hinge between rotating member 12 and transmission rod 7 is eccentric, meaning the position of the spherical hinge does not coincide with the axis of rotation of the output end of the driver 5. Consequently, when rotating member 12 rotates, the force transmitted by transmission rod 7 pulls hook 4 to move, thereby causing hook 4 to engage or disengage with the rear leg 18 of the drone 16. In this embodiment, the driver 5 is a servo motor.

[0038] In other embodiments, the driving member 5 is a cylinder, with its fixed end hinged to the first mounting base 8 and its telescopic end hinged to the hook 4. The telescopic end of the cylinder extends and retracts to achieve contact or separation between the hook 4 and the rear leg 18 of the drone 16. The hinge axes between the fixed end of the cylinder and the first mounting base 8 and between the telescopic end of the cylinder and the hook 4 extend in the vertical direction. Alternatively, the driving member 5 may be a hydraulic cylinder or an electric push rod.

[0039] like Figure 6-Figure 8 As shown, a protective cover is provided on the first mounting base 8. An installation space is formed between the protective cover and the first mounting base 8. The driving member 5, the rotating member 12, the transmission rod 7, and the hook 4 are all located in the installation space. The protective cover in this embodiment can prevent external influences on the driving member 5, the transmission rod 7, and the hook 4, thereby playing a protective role.

[0040] Because the rotating member 12 needs to rotate and has a certain length, when the height of the installation space is insufficient, it is necessary to provide an avoidance groove 15 corresponding to the position of the rotating member 12 on the protective cover. The avoidance groove 15 is connected to the installation space and is recessed outward so that the avoidance groove 15 can be used to avoid the rotating member 12 during rotation. When the rotating member 12 needs to rotate, one end of the rotating member 12 will enter the avoidance groove 15. This can prevent the protective cover from affecting the rotation of the rotating member 12 due to the insufficient height of the installation space. The provision of the avoidance groove 15 can ensure that the hook 4 can stably hook the rear leg 18 of the drone 16.

[0041] The front fixing portion in this embodiment includes a second mounting seat 11, which is provided with two front foot mounting grooves 10 for engaging with the front tripod 17 of the drone 16. The front foot mounting groove 10 has a third stop surface, which extends in a vertical direction and faces the opposite direction of the second stop surface. When the drone 16 lands and reaches the position of the front foot mounting groove 10, the second stop surface engages with the front tripod 17 of the drone 16. At the same time, because the rear tripod 18 of the drone 16 engages with the second stop surface, and the third stop surface faces the opposite direction of the second stop surface, both the front and rear sides of the drone 16 can be fixed.

[0042] The front foot mounting groove 10 in this embodiment is a trumpet-shaped groove, which faces the rear side of the drone 16. The trumpet-shaped groove makes it easier for the front leg 17 of the drone 16 to be embedded in the front foot mounting groove 10.

[0043] The second mounting seat 11 and the two first mounting seats 8 are arranged in a V shape, and the second mounting seat 11 is connected to the two first mounting seats 8 respectively, so that the second mounting seat 11 and the two first mounting seats 8 become a whole.

[0044] The undersides of both first mounting blocks 8 are equipped with freely rotatable rollers 13. These rollers 13 roll on the apron 2, thereby enabling the connected front and rear mounting portions to move on the apron 2. The apron 2 also has two parallel, spaced sliding slots extending in the same direction as the movement of the rollers 13. The undersides of both first mounting blocks 8 are equipped with connectors 14, which slide within their corresponding sliding slots.

[0045] Two fixed seats are located on the underside of the apron 2, and two linear drive assemblies are mounted on the corresponding fixed seats. Connecting members 14 pass through sliding slots and connect to the corresponding linear drive assemblies. The linear drive assemblies drive the connecting members 14 to move, thereby driving the front and rear fixed portions. At this time, the two rollers 13 roll on the apron 2, facilitating the movement of the front and rear fixed portions.

[0046] Two guides 20 are provided on the helipad 2. The two guides 20 protrude upward and correspond one-to-one with the corresponding rear foot mounting slots 9. When the drone 16 is docked on the helipad 2, the machine nest 1 will guide the drone 16 to a docking position on the helipad 2 directly in front of the two guides 20. When securing the drone 16, the front fixing portion and the two rear fixing portions move toward the guides 20. During this movement, the front leg 17 of the drone 16 enters the front foot mounting slot 10, and the rear leg 18 of the drone 16 enters the rear foot mounting slot 9, thus ensuring that the drone 16 can be properly secured.

[0047] The present invention works as follows: When the drone 16 needs to be recovered and fixed, the drone 16 lands on the apron 2, and the nest 1 guides the drone 16 to land in the correct position. Then the linear drive assembly runs to move the front fixing part and the two rear fixing parts toward the drone 16, and the front foot mounting groove 10 is engaged with the front tripod 17 of the drone 16. The rear tripod 18 of the drone 16 contacts the switch trigger 6, and the controller 23 controls the driving part 5 to drive the hook 4 to hook the rear tripod 18 of the drone 16, thereby completing the fixation of the drone 16.

[0048] When the machine nest 1 needs to release the drone 16, the linear drive member 5 runs, driving the front fixing part and the two rear fixing parts to move to the front side. While moving, the drone 16 also moves with the front fixing part and the two rear fixing parts. When it moves to the set position, the controller 23 controls the drive member 5 to open the hook 4, so that the hook 4 is separated from the rear leg 18 of the drone 16, and the rear leg 18 of the drone 16 is no longer fixed. After that, the linear drive member 5 continues to run, so that the front fixing part and the two rear fixing parts are away from the drone 16 for a distance, and then the drone 16 can take off.

[0049] Example 2 of the pusher The difference between this embodiment and embodiment 1 is that Figure 10 、 Figure 11 、 Figure 12 As shown, the rear leg 18 of the drone 16 in this embodiment has a step 19. When the hook 4 moves to the rear leg 18 of the drone 16, the hook 4 is located on the upper side of the step 19, and the step 19 forms a blocking fit with the lower side of the hook 4. In this way, even if the machine nest 1 tilts when storing the drone 16 inside, the drone 16 can be stably fixed on the apron 2, which increases the stability of the fixation of the drone 16.

[0050] Embodiment of the machine nest The machine nest 1 includes a pushing member 3, which is the pushing member 3 in the above-mentioned embodiment 1 or embodiment 2.
