Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an emergency positioning signal transmitting device for unmanned aerial vehicles. Background Art

[0002] An unmanned aerial vehicle refers to an unpiloted flying device controlled by radio remote control, which can be used for rescue, shooting, searching and other operations. Because its power supply capacity is small, it is difficult to achieve power supply and positioning for a long time after crashing and falling, thus causing difficulties for subsequent searching of the unmanned aerial vehicle.

[0003] The invention with the publication number CN104536024A discloses a self-rescue and signal positioning device for unmanned aerial vehicles, which not only locates in a timely and accurate manner, but also can effectively avoid the disadvantage that positioning cannot be achieved due to machine failure caused by insufficient power, so that the positioning information can be conveniently and accurately sent to the receiving center.

[0004] However, the above-mentioned self-rescue and signal positioning device for unmanned aerial vehicles still has the following problems in actual use: Although the long-time signal transmission of the external power supply can be realized through the positioning device, it is difficult to facilitate the search by personnel only relying on the signal transmitting device, it cannot perform autonomous detection during the falling stall process, it is difficult to take pictures and transmit the pictures of the environment during the falling process, and similarly, it cannot achieve effective protection for the device itself, thereby increasing the difficulty of searching.

[0005] Therefore, we propose an emergency positioning signal transmitting device for unmanned aerial vehicles to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide an emergency positioning signal transmitting device for unmanned aerial vehicles to solve the problems that the long-time signal transmission of the external power supply can be realized through the positioning device, but it is difficult to facilitate the search by personnel only relying on the signal transmitting device, it cannot perform autonomous detection during the falling stall process, it is difficult to take pictures and transmit the pictures of the environment during the falling process, and similarly, it cannot achieve effective protection for the device itself, thereby increasing the difficulty of searching.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An emergency positioning signal transmitting device for unmanned aerial vehicles, including a transmitting device body, and a positioning frame fixedly installed at the upper end of the transmitting device body, and the transmitting device body is installed in the middle of the belly of the unmanned aerial vehicle through the positioning frame; It further includes:

[0008] A signal transceiver is fixedly arranged in the middle of the bottom surface of the transmitting device body, and the signal transceiver is used to send the real-time coordinates and transmitted images to the controller and the mobile phone.

[0009] A driving mechanism is provided at the bottom of the main body of the transmitting device, and the driving mechanism includes a driving frame which is fixedly installed on the bottom surface of the signal transceiver.

[0010] Among them, a protective grille is fixedly arranged at the center position of the bottom surface of the driving frame, and a rotating fan module is rotatably arranged at the center position inside the driving frame.

[0011] Preferably, the four side edges of the bottom surface of the main body of the transmitting device are fixedly connected to the top ends of the telescopic sliding rods, and the bottom ends of the symmetrically arranged telescopic sliding rods penetrate through the outside of the bottom surface of the driving frame, and buffer bottom plates are fixedly arranged at the bottom ends of the symmetrically arranged telescopic sliding rods.

[0012] Preferably, the driving mechanism includes a driving rotating shaft which is rotatably arranged at the center position inside the driving frame through a bearing, and the bottom end of the driving rotating shaft is fixedly connected to the top rotating shaft of the rotating fan module, and the top end of the driving rotating shaft penetrates through the outside of the top surface of the driving frame.

[0013] Preferably, the driving mechanism includes elastic flipping rods which are fixedly installed on the outer wall of the driving rotating shaft on the top surface of the driving frame at equal angles, and the rotation of the driving rotating shaft drives the equally angled elastic flipping rods to extend outwards.

[0014] Preferably, the driving mechanism includes guiding sliding rods which are fixedly installed at the four corners of the top surface of the driving frame at equal angles, and magnetic adsorption brackets are slidably arranged on the outer walls of the equally angled guiding sliding rods, and the extension of the elastic flipping rods included in the driving mechanism adsorbs and moves the magnetic adsorption brackets inwards.

[0015] Preferably, the driving mechanism includes shooting probes which elastically slide at equal angles inside the bottom surface of the driving frame, and protective cover plates are elastically slidably arranged at the four corners of the bottom surface of the driving frame, and the equally angled protective cover plates and the shooting probes are arranged in a one-to-one correspondence.

[0016] Preferably, the protective cover plates included in the driving mechanism and the magnetic adsorption brackets on the top surface of the driving frame are connected to each other through traction steel cables. In the initial state, the protective cover plates protect the shooting probes inside the driving frame, and the movement of the protective cover plates enables the shooting probes to descend to shoot the surrounding environment for the search of the drone.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this emergency positioning signal transmitting device of the drone, through the transmitting device body installed on the belly of the drone, during the descent process, the elastic flipping rod is driven by the high-speed airflow to drive the protective cover plate to open, so that the shooting probe descends to take pictures of the falling environment, achieving the dual transmission of positioning and pictures, and improving the convenience of searching. The specific content is as follows:

[0018] 1. The transmitting device body is installed on the belly of the drone by means of bolts through the positioning frame, so as to lift and carry the whole drone, prevent the impact force during falling from damaging the drone, and at the same time, the signal transceiver always sends real-time positioning signals to the controller and the mobile phone during operation, so as to achieve the dual positioning guarantee of the drone and the transmitting device body;

[0019] Further, the fallen drone contacts and collides with the ground through the buffer bottom plate at the bottom of the telescopic sliding rods on the four sides of the transmitting device body. At the same time, after the telescopic sliding rods are stressed, the impact force is reduced by the abutting springs, and the equally angled buffer bottom plate prevents the driving frame from being knocked by hard landing, thereby improving the safety of the drone and the transmitting device body;

[0020] 2. When falling, the rotating fan module is driven to rotate by the incoming high-speed airflow, so that the outer end of the elastic flipping rod flips and extends outward. Through the attraction of opposite sexes, the magnetic adsorption bracket drives the traction steel cable to be lifted upward, so that the protective cover plate slides outward, and the shooting probe slides downward out of the driving frame to take pictures of the environment during the falling process, achieving the dual transmission of positioning and pictures, and improving the convenience of searching;

[0021] For a drone with normal takeoff and landing, the rotation speed of the rotating fan module at the bottom of its driving frame is not enough to drive the elastic flipping rod to extend and flip outward through the driving rotating shaft, so that the protective cover plate is in the initial position at the bottom of the driving frame, and then the shooting probe is protected inside the driving frame to prevent it from being knocked and damaged.

[0031] 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 the embodiments. Based on the embodiments in 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.

[0032] Please refer to Figures 1-8 , the present utility model provides the following technical solutions:

[0033] Embodiment 1: To solve the problems existing in the use of the launch device body 1 of the existing unmanned aerial vehicle, therefore, through the following technical solutions in this embodiment, an emergency positioning signal transmitting device for an unmanned aerial vehicle includes a launch device body 1 and a positioning frame 2 fixedly installed on the upper end of the launch device body 1, and the launch device body 1 is installed in the middle of the belly of the unmanned aerial vehicle through the positioning frame 2; a signal transceiver 3 is fixedly arranged in the middle of the bottom surface of the launch device body 1, and the signal transceiver 3 is used to send the real-time coordinates and transmitted images to the controller and the mobile phone; a driving mechanism is arranged at the bottom of the launch device body 1, and the driving mechanism includes a driving frame 4, and the driving frame 4 is fixedly installed on the bottom surface of the signal transceiver 3.

[0034] The four side edges of the bottom surface of the launch device body 1 are fixedly connected to the top ends of the telescopic slide rods 7, and the bottom ends of the symmetrically arranged telescopic slide rods 7 penetrate through the outside of the bottom surface of the driving frame 4, and buffer bottom plates 8 are fixedly arranged at the bottom ends of the symmetrically arranged telescopic slide rods 7.

[0035] AsFigures 1-2 As shown, the launch device body 1 is fixedly installed on the middle part of the belly of the UAV through the positioning frame 2 arranged above by bolts, so that the launch device body 1 is located at the bottom of the UAV, and the signal transceiver 3 fixedly installed on the middle part of the bottom surface of the launch device body 1 always sends real-time positioning signals to the controller and the mobile phone during operation, so as to realize the dual positioning guarantee of the UAV and the launch device body 1;

[0036] Furthermore, when the UAV stalls and falls, it is lifted by the launch device body 1 at the bottom of the UAV, and the telescopic slide rods 7 arranged on the four sides of the launch device body 1 contact and collide with the ground through the buffer bottom plate 8 at the bottom. After the telescopic slide rods 7 are subjected to force, the impact force is reduced by the resistance spring, and the buffer bottom plate 8 at the same angle prevents the drive frame 4 from colliding through a hard landing, thereby improving the safety of the UAV and the launch device body 1.

[0037] Embodiment 2: In order to solve the problems existing in the use of the launch device body 1 of the existing drone, the present embodiment adopts the following technical scheme, wherein a protective grille 5 is fixedly provided at the center position of the bottom surface of the driving frame 4, and a rotating fan module 6 is rotatably provided at the inner center position of the driving frame 4; the driving mechanism includes a driving shaft 9, and the driving shaft 9 is rotatably provided at the inner center position of the driving frame 4 through a bearing, and the bottom end of the driving shaft 9 is fixedly connected to the top shaft of the rotating fan module 6, and the top end of the driving shaft 9 is penetrated and provided on the outside of the top surface of the driving frame 4; the driving mechanism comprises a driving shaft 9, and the driving shaft 9 is rotatably provided at the inner center position of the driving frame 4 through a bearing, and the bottom end of the driving shaft 9 is fixedly connected to the top shaft of the rotating fan module 6, and the top end of the driving shaft 9 is penetrated and provided on the outside of the top surface of the driving frame 4; The driving mechanism includes an elastic flip rod 10, and the elastic flip rod 10 is fixedly installed at an equal angle on the outer wall of the driving shaft 9 on the top surface of the driving frame 4, and the rotation of the driving shaft 9 drives the elastic flip rod 10 set at an equal angle to extend outward; the driving mechanism includes a guide slide bar 11, and the guide slide bar 11 is fixedly installed at an equal angle at the four corners of the top surface of the driving frame 4, and a magnetic adsorption bracket 12 is slidably provided on the outer wall of the guide slide bar 11 set at an equal angle, and the magnetic adsorption bracket 12 is adsorbed and moved inward by the extension of the elastic flip rod 10 included in the driving mechanism.

[0038] The driving mechanism includes a shooting probe 13, and the shooting probe 13 elastically slides at equal angles inside the bottom surface of the driving frame 4, and protective cover plates 14 are elastically slidably arranged at the four corners of the bottom surface of the driving frame 4, and the protective cover plates 14 arranged at equal angles are arranged in a corresponding distribution with the shooting probe 13; the protective cover plate 14 included in the driving mechanism and the magnetic adsorption bracket 12 on the top surface of the driving frame 4 are interconnected by a traction steel cable 15, and the protective cover plate 14 in the initial state protects the shooting probe 13 from the inside of the driving frame 4, and the shooting probe 13 is allowed to descend to shoot the environment through the movement of the protective cover plate 14, so as to search for drones.

[0039] As Figures 3-8 shown, when the UAV carrying the launching device body 1 on the bottom surface falls, the lowermost driving frame 4 enters high-speed airflow inside, and the high-speed airflow drives the fan module 6 inside the driving frame 4 to rotate. Then, the driving rotating shaft 9 fixedly connected to the top of the rotating shaft and the elastic flipping rod 10 are driven to rotate. At the same time, under the action of centrifugal force, the outer end of the elastic flipping rod 10 extends and flips outward. When passing through the magnetically adsorbed brackets 12 arranged at equal angles, through the action of attracting opposite poles, it drives the magnetically adsorbed brackets 12 to slide inward along the extended guiding slide rod 11. At the same time, the magnetically adsorbed brackets 12 also drive the traction steel cable 15 to lift upward, so as to drive the protective cover plate 14 at the bottom end of the fixedly connected traction steel cable 15 to slide outward, so that the camera probe 13 no longer resisted by the protective cover plate 14 slides downward out of the driving frame 4 to take pictures of the environment during the falling process. Finally, the signal transceiver 3 transmits to the controller and the mobile phone terminal to achieve the dual transmission of positioning and pictures, improving the convenience of search;

[0040] Further, when the UAV falls under normal circumstances, it will not drive the fan module 6 inside the driving frame 4 to work (or the rotation speed of the fan module 6 is not enough to drive the elastic flipping rod 10 to extend and flip outward through the driving rotating shaft 9), so that the protective cover plate 14 is in the initial position at the bottom of the driving frame 4, and then the camera probe 13 is protected inside the driving frame 4 to prevent it from being damaged due to bumping.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
