Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) relay device technology, specifically a distributed UAV signal relay sharing device. Background Technology

[0002] When a drone goes beyond the range of the remote control signal, the remote control and the drone cannot communicate normally, and the drone is prone to abnormalities and accidents. The remote control signal transmission distance can be increased by setting up a remote control signal relay device.

[0003] Currently, wireless repeaters on drones are mostly fixed to the drone body directly using screws or bolts. Although the fixation is relatively stable, the above installation method also makes the installation and disassembly of wireless repeaters on drones inconvenient, requiring the use of tools for disassembly and assembly. This is not conducive to the daily maintenance and repair of wireless repeaters on drones. Therefore, we urgently need a distributed drone signal repeater sharing device. Utility Model Content

[0004] The purpose of this utility model is to provide a distributed unmanned aerial vehicle (UAV) signal relay sharing device to solve the problem mentioned in the background art that the existing wireless relays on UAVs are mostly directly fixed to the UAV body using screws or bolts. Although the fixation is relatively stable, the above-mentioned installation method also makes the installation and disassembly of the wireless relays on the UAVs inconvenient, requiring the use of tools for disassembly and assembly, which is not conducive to the daily maintenance and repair of the wireless relays on the UAVs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a distributed UAV signal relay sharing device, including a relay device, a disassembly mechanism externally provided on the relay device, and a heat dissipation mechanism externally provided on the relay device;

[0006] The disassembly mechanism includes a fixing frame, the top of which has a groove, a lead screw is rotatably connected to the inner side of the groove, a moving block is threaded to the outer side of the lead screw, a positioning frame is fixedly connected to the top of the moving block, a threaded rod is rotatably connected to one end of the positioning frame, a fixing block is installed at the bottom of the threaded rod, a suction cup is installed at the bottom of the fixing block, and a limiting rod is fixedly connected to one end of the fixing block.

[0007] Preferably, multiple fixing frames are provided, and the multiple fixing frames are arranged in a rectangular array.

[0008] Preferably, one end of the lead screw passes through the fixing frame and extends to the outside of the fixing frame, and a rotating block is fixedly connected to one end of the lead screw.

[0009] Preferably, there are two limiting rods, and one end of each limiting rod is slidably connected to one end of the positioning frame.

[0010] Preferably, the heat dissipation mechanism includes a heat dissipation shell, a heat-conducting plate is snapped into the inside of the heat dissipation shell, and heat dissipation holes are opened on the outside of the heat dissipation shell.

[0011] Preferably, one end of the heat-conducting plate is screwed to one end of the relay device, and one end of the heat sink is rotatably connected to one end of the fixing frame.

[0012] Preferably, there are two heat dissipation holes, and the two heat dissipation holes are equipped with dustproof nets.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this utility model involves attaching the heat dissipation shell to the bottom of the drone, then adjusting the position of the fixing bracket by rotating it so that it aligns with the four sides of the drone. Next, a rotating block rotates the lead screw, causing the moving block outside the lead screw to move within a groove, thus moving the positioning bracket towards the end face of the drone until it contacts and adheres to the end face. A buffer pad is provided at the contact end between the positioning bracket and the drone to prevent rigid damage to the drone. This process is repeated until all four fixing brackets are in contact with the drone. Finally, the threaded rod is turned to push the fixing block downwards, and the top of the fixing block... Two limiting rods limit the descent of the fixing block, making its descent more stable. Simultaneously, the limiting rods are slidably connected to the positioning frame, allowing them to descend synchronously with the fixing block, maintaining the limiting effect until the suction cup at the bottom of the fixing block presses against the top of the drone, thus securing it and completing the installation of the relay equipment. For disassembly, simply rotate the threaded rod to detach the suction cup from the drone, and then rotate the screw to detach the positioning frame from the drone to release the fixation. This achieves convenient installation and fixation. Furthermore, this application utilizes a multi-transmitter switching module to simultaneously relay signals between multiple drones and remote control devices, enabling signal sharing among multiple drones.

[0015] Secondly, this utility model connects the relay device to the heat-conducting plate, allowing the heat-conducting plate to conduct heat generated by the relay device. The heat-conducting plate is then snapped into the interior of the heat sink, dividing the heat sink into two parts. The heat dissipation holes allow airflow to reach the heat-conducting plate of the heat sink during drone flight, carrying away the heat. The dustproof net prevents dust from entering the heat sink, thus achieving the heat dissipation effect. Attached Figure Description

[0021] 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.

[0022] This utility model provides the following technical solution:

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A distributed unmanned aerial vehicle (UAV) signal relay sharing device includes a relay device 1, a disassembly mechanism 2 externally provided on the relay device 1, and a heat dissipation mechanism 3 externally provided on the relay device 1.

[0025] The disassembly mechanism 2 includes a fixing frame 21. The top of the fixing frame 21 has a groove. A lead screw 22 is rotatably connected to the inner side of the groove. A moving block 23 is threadedly connected to the outer side of the lead screw 22. A positioning frame 24 is fixedly connected to the top of the moving block 23. A threaded rod 25 is rotatably connected to one end of the positioning frame 24. A fixing block 26 is installed at the bottom of the threaded rod 25. A suction cup 27 is installed at the bottom of the fixing block 26. A limiting rod 28 is fixedly connected to one end of the fixing block 26.

[0026] Multiple fixtures 21 are provided, and the multiple fixtures 21 are arranged in a rectangular array.

[0027] One end of the lead screw 22 passes through the fixed frame 21 and extends to the outside of the fixed frame 21. A rotating block 29 is fixedly connected to one end of the lead screw 22.

[0028] There are two limit rods 28, and one end of each limit rod 28 is slidably connected to one end of the positioning frame 24.

[0029] Through the above technical solution, the heat sink 31 is attached to the bottom of the drone. Then, the position of the fixing bracket 21 is adjusted by rotating it so that it corresponds to the four sides of the drone. Then, the lead screw 22 is rotated by the rotating block 29, thereby driving the moving block 23 outside the lead screw 22 to move in the groove, thereby driving the positioning bracket 24 to move towards the end face of the drone until the positioning bracket 24 contacts and fits against the end face of the drone. The contact end of the positioning bracket 24 with the drone is provided with a buffer pad to avoid rigid damage to the drone. Then, the above operation is repeated so that all four fixing brackets 21 are in contact with the drone. Then, the fixing block 26 is pushed down by turning the threaded rod 25, and the fixing block 26 pushes down. The two limiting rods 28 of the device limit the fixing block 26, making the descent of the fixing block 26 more stable. At the same time, the limiting rods 28 are slidably connected to the positioning frame 24, so that the limiting rods 28 descend synchronously with the descent of the fixing block 26, maintaining the limiting effect until the suction cup 27 at the bottom of the fixing block 26 presses against the top of the drone, thereby adhering to it and completing the installation of the relay device 1. For disassembly, simply rotate the threaded rod 25 to detach the suction cup 27 from the drone, and then rotate the screw 22 to detach the positioning frame 24 from the drone to release the fixation, thus achieving the effect of convenient installation and fixation. In addition, this application uses a multi-transmitter switching module to simultaneously relay between multiple drones and remote control devices, enabling signal sharing between multiple drones.

[0030] Example 2

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the heat dissipation mechanism 3 includes a heat dissipation shell 31, a heat conduction plate 32 is snapped into the inside of the heat dissipation shell 31, and heat dissipation holes 33 are opened on the outside of the heat dissipation shell 31.

[0032] One end of the heat-conducting plate 32 is screwed to one end of the relay device 1, and one end of the heat sink 31 is fixedly connected to one end of the mounting bracket 21.

[0033] There are two heat dissipation holes 33, and the two heat dissipation holes 33 are equipped with dustproof screens.

[0034] Through the above technical solution, by connecting the relay device 1 to the heat conduction plate 32, and having the antenna of the relay device 1 protrude through the heat dissipation shell 31, the heat conduction plate 32 can conduct heat generated by the relay device 1. Then, by the heat conduction plate 32 being snapped into the interior of the heat dissipation shell 31, the heat dissipation shell 31 is divided into two parts. Then, through the heat dissipation holes 33, when the UAV is flying, the airflow can reach the heat conduction plate 32 of the heat dissipation shell 31 through the heat dissipation holes 33, carrying away the heat. And through the dustproof net, dust is prevented from entering the heat dissipation shell 31, thereby achieving the effect of heat dissipation.
