[0002] A drone nest is an intelligent infrastructure designed for drones to automatically take off and land, charge, exchange data, and store data. Its core function is to provide drones with all-weather autonomous services, and it is especially suitable for scenarios that require high-frequency and large-scale operations.

[0003] When opening the drone pod, hinges are mostly used to separate and move the two side doors of the drone pod to the left and right sides of the drone pod, so that the drone can be landed in the drone pod's internal platform. The hinge plays an important role in rotating and connecting the door and the drone pod body. However, in existing hinges, the connection of the shaft, pin and blade is often achieved by welding or riveting interference fit. This method is not convenient for separating the hinge, which will affect the speed and efficiency of hinge maintenance, upkeep and replacement. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-5 The present invention provides the following technical solution:

[0031] A drone pod opening hinge structure includes:

[0032] Second blade 3;

[0033] A first blade 1 is rotatably disposed on one side of a second blade 3, and a connecting block 8 is fixedly connected to one end of the first blade 1, and a rotating shaft 12 is fixedly connected to one end of the connecting block 8; and

[0034] Two sets of disassembly and assembly mechanisms are provided. Each set of disassembly and assembly mechanisms consists of a rotating sleeve 7, a mounting block 4, a fixing groove 14, a shaft pin 15, a pull plate 5, and a first spring 6. The mounting block 4 is fixedly connected to one end of the second blade 3. The rotating sleeve 7 is integrally formed on the lower end of the mounting block 4. The fixing groove 14 is opened at one end of the mounting block 4, the rotating sleeve 7, and the rotating shaft 12. The first spring 6 is fixedly connected to the upper end of the mounting block 4. The pull plate 5 is fixedly connected to the upper end of the first spring 6. The shaft pin 15 is fixedly connected to the lower end of the pull plate 5.

[0035] In a specific embodiment of this utility model, when it is necessary to separate the first blade 1 and the second blade 3, the two pull plates 5 are pulled towards the opposite ends. As the two pull plates 5 move towards the opposite ends, the two shaft pins 15 will be pulled out from the fixed grooves 14 located in the rotating shaft 12. Without the restriction of the shaft pins 15, the rotating shaft 12 can be pulled out from the two rotating sleeves 7, which facilitates the maintenance or replacement of the device. After maintenance, the rotating shaft 12 is placed back between the two rotating sleeves 7. Through the elastic pull of the first spring 6, the two pull plates 5 are moved towards the opposite ends, thereby allowing the two shaft pins 15 to be re-inserted into the two fixed grooves 14, fixing the rotating shaft 12 between the two rotating sleeves 7 for rotation. The first blade 1 can be connected through the connecting block 8. In this device, the traditional single shaft pin 15 is replaced with two, so that if one shaft pin 15 is damaged, the other shaft pin 15 can still perform the replacement work, which greatly enhances the stability of the device. The first blade 1 and the second blade 3 can be connected to the drone nest body and the drone cabin door, respectively.

[0036] Please refer to the details. Figure 2 It also includes two sets of calibration mechanisms. Each set of calibration mechanisms consists of a second spring 21 and a stop plate 19. The second spring 21 is fixedly connected to one end of the second blade 3, and the stop plate 19 is fixedly connected to one end of the second spring 21. A diversion groove 13 is provided inside the rotating shaft 12, and an injection groove 16 is provided on the inner circumference of the diversion groove 13.

[0037] Preferably, a telescopic rod 20 is fixedly connected between the abutment plate 19 and the second blade 3, and the second spring 21 is sleeved on the circumferential surface of the telescopic rod 20.

[0038] In this embodiment: when the rotating shaft 12 continues to move between the two rotating sleeves 7, the rotating shaft 12 will continuously abut against the abutment plate 19, and the abutment plate 19 will squeeze the telescopic rod 20. When the telescopic rod 20 is squeezed to its maximum stroke, it will abut against the abutment plate 19 and the rotating shaft 12, making the rotating shaft 12 unable to move. At this time, the rotating shaft 12 will be in the middle position of the two rotating sleeves 7, which facilitates the quick use of the disassembly and assembly mechanism. Lubricating oil can be injected through the injection groove 16, and then evenly distributed between the two fixed grooves 14 and the shaft pin 15 through the diversion groove 13, improving the uniformity and speed of lubrication.

[0039] Please refer to the details. Figure 2 The inner circumference of the injection groove 16 is provided with a threaded groove, and a threaded rod 17 is threadedly connected in the threaded groove. One end of the threaded rod 17 is fixedly connected to a connecting nut 10, and one end of the connecting nut 10 is provided with a wrench groove 11, which is hexagonal.

[0040] In this embodiment: the threaded rod 17 connected by the internal thread of the threaded groove can easily block and close the injection groove 16 to prevent the lubricating oil from flowing back. The wrench groove 11 opened at one end of the connecting nut 10 can be easily rotated clockwise or counterclockwise with a hex wrench.

[0041] Please refer to the details. Figure 3 One end of the connecting block 8 is provided with a packaging groove 9, and one end of the first blade 1 and the second blade 3 are each provided with two connecting grooves 2. The circumferential surface of the pull plate 5 is provided with anti-slip grooves, and one end of the abutment plate 19 is provided with multiple lubrication grooves. Each of the multiple lubrication grooves is fixedly connected with a ball bearing 18.

[0042] In this embodiment: the packaging groove 9 allows the first blade 1 to be conveniently placed in the packaging and to be easily removed; the multiple connecting grooves 2 facilitate the connection of the first blade 1 and the second blade 3 to the drone nest or drone nest door; the anti-slip groove prevents the user from slipping when using the pull plate 5; and the ball bearing 18 reduces the friction that occurs when the rotating shaft 12 and the abutment plate 19 come into contact.

[0043] The working principle and usage process of this utility model are as follows: When it is necessary to separate the first blade 1 and the second blade 3, the two pulling plates 5 are pulled to the opposite ends. While the two pulling plates 5 are moving to the opposite ends, the two shaft pins 15 will be pulled out from the fixed grooves 14 located in the rotating shaft 12. Without the restriction of the shaft pins 15, the rotating shaft 12 can be pulled out from the two rotating sleeves 7, which is convenient for maintenance or replacement of the device. After maintenance, the rotating shaft 12 is placed back between the two rotating sleeves 7. Through the elastic pull of the first spring 6, the two pulling plates 5 are moved to the opposite ends, so that the two shaft pins 15 are re-inserted into the two fixed grooves 14, and the rotating shaft 12 is fixed between the two rotating sleeves 7 for rotation.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
