Description

Technical Field

[0001] The utility model relates to the technical field of cable auxiliary fixation, in particular to a tethered cable auxiliary structure for an unmanned aerial vehicle (UAV). Background Art

[0002] The tethered UAV overcomes the problem of short endurance time of traditional multi-rotor UAVs. The ground power supply continuously supplies electric energy through an optical and electrical composite cable, and the UAV can stay in the air for a long time. Therefore, the development of tethered UAVs is rapid and the application scope is also becoming wider and wider. For example, in the intelligent emergency disconnection mechanism of a tethered UAV recorded in the patent publication number CN215554203U, it includes a support body, a driving device and a power supply mechanism fixed at the bottom of the UAV body; the support body includes a first fixing plate and a second fixing plate, and a baffle is installed and connected between the bottom ends of the first fixing plate and the second fixing plate; the power supply mechanism includes a tethered cable, a male aviation plug and a female aviation plug. The tethered cable is divided into an airborne end tethered cable and a ground end tethered cable, and one end of the airborne end tethered cable is connected to the male aviation plug;

[0003] Although the above structure has the function of separating the tethered cable from the UAV in the air, however, the device needs to be installed on the lower surface of the airframe using threaded fixing components. This installation structure requires prefabricated threaded holes on the lower surface of the airframe, and professional tools are needed for both disassembly and assembly, resulting in inconvenient disassembly and assembly of the auxiliary structure and a reduced scope of application. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tethered cable auxiliary structure for an unmanned aerial vehicle to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tethered cable auxiliary structure for an unmanned aerial vehicle includes a pressing seat installed on the lower surface of the UAV main body. A fixing sleeve is movably connected in the front direction of the pressing seat. A rubber sleeve is movably connected inside the fixing sleeve, and the rubber sleeve is used to fix the main body of the retention wire. An installation module is nested and connected to the outer surface of the pressing seat. Connection modules are arranged on both side surfaces of the installation module. The installation module is used to cooperate with the connection modules to connect with the UAV main body. A guiding seat is fixedly connected to the side surface of the installation module, and the guiding seat is used to guide the fixing sleeve.

[0007] Furthermore: Two extension frames are fixedly connected to the rear surface of the fixing sleeve. A guiding rod is fixedly connected to the rear surface of the guiding seat, and the guiding rod is slidably connected with the extension frames.

[0008] Furthermore: A pressing rod is fixedly connected to the lower surface of the pressing seat.

[0009] Furthermore, the installation module includes an installation plate which is nested and connected to the outer surface of the extrusion rod. A mounting seat is fixedly connected to the outer surface of the installation plate at a position facing away from the guide seat. A screw rod is rotatably connected inside the mounting seat. A motor is fixedly connected to the rear surface of the mounting seat, and the output end of the motor is fixedly connected to the screw rod. One of the extension brackets is threadedly connected to the screw rod. The control box is fixedly connected to the outer surface of the installation plate at a position facing away from the installation plate, and the control box is electrically connected to the motor.

[0010] Furthermore, the connection module includes a limiting strip which is fixedly connected to both side surfaces of the installation plate. A sliding groove is formed on the rear surface of the limiting strip, and a sliding block is slidably connected inside the sliding groove. A hook is fixedly connected to the side surface of the sliding block, and a bolt is threadedly connected to the rear surface of the sliding block.

[0011] Furthermore, an extrusion bolt is threadedly connected to the lower surface of the installation plate, and one end of the extrusion bolt abuts against the lower surface of the extrusion seat.

[0012] Furthermore, a chuck is fixedly connected to the lower surface of the rubber sleeve, and the fixed sleeve is in close contact with the chuck.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When in use, slide the sliding block along the limiting strip to adjust the position of the hook, and then rotate the bolt to fix the sliding block. Therefore, when the distance between the installation module and the extrusion seat increases, the hook is in close contact with the support leg of the drone body to complete the fixation of the installation module. The adjustable fixation structure is convenient for connecting with different drone bodies, and when disassembling, only the extrusion bolt needs to be rotated, which is convenient for the quick disassembly and assembly of the auxiliary structure;

[0015] 2. The extension bracket drives the fixed sleeve to move backward, so that the fixed sleeve cooperates with the installation plate to clamp the rubber sleeve to fix the main body of the stay wire, preventing the main body of the stay wire from falling off during the flight of the drone body and affecting the endurance of the drone body. When the fixed sleeve moves forward, the inner surface of the fixed sleeve presses the main body of the stay wire during the forward movement, and the chuck is in contact with the fixed sleeve, which is convenient for separating the main body of the stay wire from the drone body, so that the drone body can be freed from the restriction of the main body of the stay wire and fly freely.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a tethered cable auxiliary structure for a UAV includes an extrusion seat 6 installed on the lower surface of the UAV main body 1. A fixing sleeve 4 is movably connected to the front side of the extrusion seat 6. A rubber sleeve 402 is movably connected inside the fixing sleeve 4. The rubber sleeve 402 is used to fix the stay wire main body 5. The outer surface of the extrusion seat 6 is nested with an installation module 2. Connection modules 3 are provided on both side surfaces of the installation module 2. The installation module 2 is used to cooperate with the connection modules 3 to connect with the UAV main body 1. A guiding seat 7 is fixedly connected to the side surface of the installation module 2. The guiding seat 7 is used to guide the fixing sleeve 4.

[0023] Specifically, when in use, the extrusion seat 6 contacts the UAV main body 1, and the extrusion seat 6 applies a downward force to the installation module 2, so that the installation module 2 cooperates with the connection module 3 to squeeze the support leg part of the UAV main body 1, further fixing the installation module 2 and the connection module 3. At this time, the stay wire main body 5 passes through the fixing sleeve 4 and then is connected to the UAV main body 1. The fixing sleeve 4 fixes the stay wire main body 5, avoiding the detachment of the stay wire main body 5 joint position due to stress when the UAV main body 1 ascends. When it is necessary to fly using the power supply of the UAV main body 1 itself, the fixing sleeve 4 moves forward, separating the stay wire main body 5 from the UAV main body 1, facilitating the free flight of the UAV main body 1.

[0024] Embodiment 1

[0025] Such asFigures 1 - 3 As shown, the rear surface of the fixing sleeve 4 is fixedly connected to two extension frames 401 , the rear surface of the guide seat 7 is fixedly connected to a guide rod 701 , the guide rod 701 and the extension frames 401 are slidably connected, and the lower surface of the extrusion seat 6 is fixedly connected to an extrusion rod 601 .

[0026] In this embodiment, the extension frame 401 cooperates with the guide rod 701 to limit the movement of the fixing sleeve 4, the extrusion rod 601 is used to limit the movement of the mounting plate 201, and the extension frame 401 cooperates with the screw rod 203 to drive the fixing sleeve 4 to move.

[0027] like Figures 3 - 4 As shown, the mounting module 2 includes a mounting plate 201, which is nested and connected to the outer surface of the extrusion rod 601, and the outer surface of the mounting plate 201 is fixedly connected to a mounting seat 202 at a position away from the guide seat 7, and the inner rotation of the mounting seat 202 is connected to a screw 203, and the rear surface of the mounting seat 202 is fixedly connected to a motor 204, and the output end of the motor 204 is fixedly connected to the screw 203, one of the extension frames 401 is threadedly connected to the screw 203, and the control box 205 is fixedly connected to the outer surface of the mounting plate 201 away from the mounting plate 201, and the control box 205 is electrically connected to the motor 204, and the lower surface of the mounting plate 201 is threadedly connected to an extrusion bolt 602, one end of the extrusion bolt 602 is in conflict with the lower surface of the extrusion seat 6, and the lower surface of the rubber sleeve 402 is fixedly connected to a chuck, and the fixing sleeve 4 is in close contact with the chuck.

[0028] In this embodiment, the extrusion bolt 602 is manually rotated, and the output end of the extrusion bolt 602 squeezes the extrusion seat 6, so that the distance between the installation module 2 and the extrusion seat 6 is increased, so that the connection module 3 and the inclined support leg are in contact. The control box 205 has a built-in power supply and a single-chip microcomputer and a wireless control switch receiver for controlling the rotation of the motor 204. The remote control of the motor 204 here belongs to the prior art and is not described in detail herein. Therefore, when the motor 204 rotates, it drives the screw rod 203 to rotate. Under the push of the thread, the extension frame 401 drives the fixing sleeve 4 to move to the rear side, so that the fixing sleeve 4 cooperates with the mounting plate 201 to clamp. The rubber sleeve 402 fixes the retention line body 5 to prevent the retention line body 5 from falling off when the drone body 1 is flying, which affects the endurance of the drone body 1. When the retention line body 5 needs to be removed so that the drone body 1 can fly freely using its own power supply, the motor 204 drives the screw 203 to rotate in the opposite direction to move the fixing sleeve 4 forward. When moving forward, the inner surface of the fixing sleeve 4 squeezes the retention line body 5, and the chuck and the fixing sleeve 4 are in contact, which makes it easy to separate the retention line body 5 from the drone body 1, so that the drone body 1 loses the restriction of the retention line body 5 and the drone body 1 can fly freely.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, in order to make up for the problem that it is inconvenient to install the installation module 2 in the first embodiment.

[0031] As Figures 1 - 4 shown, the connection module 3 includes a limiting strip 301, the limiting strip 301 is fixedly connected to both side surfaces of the mounting plate 201, a sliding groove 302 is formed on the rear surface of the limiting strip 301, a slider 303 is slidably connected inside the sliding groove 302, a hook 304 is fixedly connected to the side surface of the slider 303, and a bolt 305 is threadedly connected to the rear surface of the slider 303.

[0032] In this embodiment, when in use, the slider 303 is slid along the limiting strip 301 to adjust the position of the hook 304, and then the bolt 305 is rotated to fix the slider 303. Therefore, when the distance between the installation module 2 and the extrusion seat 6 increases, the hook 304 is in close contact with the support leg of the drone body 1, and the installation module 2 is fixed. The adjustable fixing structure is convenient for connecting with different drone bodies 1, and when disassembling, only the extrusion bolt 602 needs to be rotated, which is convenient for the quick disassembly and assembly of the auxiliary structure.
