Description

Technical Field

[0001] The invention relates to a target tracking display device, and more particularly to an unmanned aerial vehicle signal directional display and an assembly structure thereof. Background Art

[0002] Unmanned aerial vehicles are unmanned aerial vehicles that are controlled by radio remote control equipment and self-contained program control devices. They have been widely used in aerial photography, agriculture, plant protection, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting and other fields.

[0003] When a UAV is performing a mission, its position in the air is usually indicated by the signal light on its fuselage. However, when flying at a long distance, at night, or in weather with poor visibility, it is often difficult for ground operators to accurately distinguish the position of the UAV. Although some UAV remote control devices are equipped with a flight trajectory recording function, the position information it reflects is not intuitive, which brings great inconvenience to remote control operations. In serious cases, it may even cause the flight direction to be lost and out of the remote control range, leading to a crash. Therefore, allowing operators to intuitively grasp the position of the UAV in the air is very helpful in improving the convenience and reliability of control.

[0004] In addition, due to the different operating levels of operators and the failure of the unmanned aerial vehicle itself, the phenomenon of unmanned aerial vehicle crashes also occurs from time to time. Since the location of the crash is difficult to accurately determine, the labor intensity and difficulty of finding the aircraft are increased, and some aircraft cannot be found, causing losses to users. Although many technicians have proposed solutions such as unmanned aerial vehicle search instruments in the prior art, they mainly rely on the positioning signal on the aircraft and cooperate with mobile terminals to determine the crash location, which is still difficult to find.

[0005] Based on the above problems, if the position of the UAV can be displayed 360° on the ground, it will certainly be of great help in determining the position of the UAV. The light display within a 360° range is a simple and effective method. After determining the position of the UAV in the air using signal transceiver technology, the corresponding position of the UAV is displayed by lighting or flashing the corresponding lights within a circle, which can help the operator accurately and intuitively determine the current position of the aircraft. However, in the signal directional display, the precise 360° ring assembly of the LED light is also one of the difficulties, especially the installation of the flexible LED light bar on the ring holder. The outer circumference of the ring holder is evenly distributed with a number of light-transmitting holes. The assembly requires that the lamp beads on the LED light bar accurately correspond to the corresponding light-transmitting holes. During actual assembly, it was found that although the position accuracy of the lamp beads on the LED light strip and the light-transmitting holes on the annular holder was very high, the circular ring formed by the LED light strip was not easy to form a standard circle, and the concentricity of the LED light ring and the annular holder was also difficult to ensure. This resulted in cumulative errors when aligning the lamp beads with the corresponding light-transmitting holes, which in turn made it difficult for the lamp beads on the LED light strip to be fully and accurately aligned with the light-transmitting holes on the annular holder, affecting the display effect of the signal directional display. Summary of the invention

[0006] 1. Technical problem to be solved by the invention

By adopting the technical solution of the present invention, the LED light bar is installed using the inner circle, which ensures the standard degree of the LED light bar forming a circular ring, so that the circumference of each lamp bead is evenly distributed, and the inner circle and the outer circle are coaxially installed and fixed, so that the index angle of each lamp bead and the corresponding light-transmitting hole is equal, thereby achieving accurate alignment of the circularly distributed lamp beads with each light-transmitting hole, greatly improving the assembly accuracy, and meeting the lighting display effect of the unmanned aerial vehicle signal directional display.

[0008] Another object of the present invention is to provide an unmanned aerial vehicle signal directional display, which includes a light ring display assembly and a control module installed on the inner side of the light ring display assembly. The control module is electrically connected to the LED light bar in the light ring display assembly, and is used to control the working status of each lamp bead on the LED light bar to display the direction of the unmanned aerial vehicle signal, so that ground operators can intuitively grasp the position of the unmanned aerial vehicle in the air, thereby improving the operational reliability of the unmanned aerial vehicle in an environment with poor visibility; at the same time, in the event of an accidental crash, the signal directional display can also be used to quickly lock the crash direction, providing convenience for the search for the unmanned aerial vehicle.

DETAILED DESCRIPTION

[0041] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0042] [Example 1]

[0043] This embodiment discloses an assembly structure of an unmanned aerial vehicle signal directional display. Figures 1 to 5As shown, the assembly structure of the unmanned aerial vehicle signal directional display comprises an outer ring 1, an inner ring 2 and an LED light bar 3. The outer ring 1 has a plurality of light-transmitting holes 1-1 evenly distributed circumferentially on the ring body. The LED light bar 3 has a plurality of lamp beads 3-1 distributed in an array. The base material of the LED light bar 3 is flexible so that the LED light bar 3 can be bent. The LED light bar 3 is wound around the circumference and fixed on the outer wall of the inner ring 2. The lamp beads 3-1 face the outside of the inner ring 2 and are evenly distributed circumferentially on the inner ring 2. The inner ring 2 is fixed to the inner ring 2. The LED light bar 3 is fixed, which can ensure the standard degree of the circle formed by the LED light bar 3, so that the lamp beads 3-1 are evenly distributed circumferentially; the maximum outer diameter of the LED light bar 3 after being installed on the inner ring 2 is smaller than the inner diameter of the outer ring 1, that is, there is a certain side gap between the protruding lamp beads 3-1 and the inner wall of the outer ring 1, so that the inner ring 2 assembled with the LED light bar 3 can be smoothly installed in the outer ring 1, and the above-mentioned side gap can be as small as possible, for example, the side gap is set to about 1mm, so that the lamp beads 3-1 can be closer to the corresponding light-transmitting holes 1-1. The inner ring 2 is coaxially fixedly installed on the inner side of the outer ring 1, and the lamp beads 3-1 on the LED light bar 3 correspond one by one to the light-transmitting holes 1-1 on the outer ring 1. Since the LED light bar 3 and the inner ring 2 have good coaxiality, the coaxiality of the circle where the lamp beads 3-1 on the LED light bar 3 are located and the outer ring 1 can be guaranteed. During assembly, the LED light strip 3 is first wound around the outside of the inner ring 2 and fixed, and then the two are assembled together on the outer ring 1. The LED light strip 3 is installed using the inner ring 2 to ensure the standard degree of the LED light strip 3 forming a circular ring, so that each lamp bead 3-1 is evenly distributed on the circumference. The inner ring 2 and the outer ring 1 are coaxially installed and fixed so that the index angles of each lamp bead 3-1 and the corresponding light-transmitting hole 1-1 are equal, thereby achieving accurate alignment of the circularly distributed lamp beads 3-1 with each light-transmitting hole 1-1, greatly improving the assembly accuracy and satisfying the light display effect of the unmanned aerial vehicle signal directional display.

[0044] Reference Figures 4 to 6 As shown, in this embodiment, one side of the outer ring 1 is provided with an outer ring edge body 1-2 extending outward, and a step groove 1-3 is provided on the upper end surface of the outer ring edge body 1-2, and one side of the inner ring 2 is provided with an inner ring edge body 2-1 extending outward, and the outer contour size of the inner ring edge body 2-1 is adapted to the outer contour size of the step groove 1-3, and the coaxiality of the outer ring 1 and the inner ring 2 is ensured by the cooperation of the inner ring edge body 2-1 and the step groove 1-3. During assembly, it is only necessary to ensure the coaxiality of the outer ring 1 and the inner ring 2 by ensuring the cooperation accuracy of the inner ring edge body 2-1 and the step groove 1-3, which makes it easier to ensure the coaxiality of the LED light strip 3 after winding and the outer ring 1, thereby ensuring assembly accuracy and convenience. The depth of the above-mentioned step groove 1-3 can be equal to the height of the inner ring edge body 2-1, so that the upper end surfaces of the inner and outer rings are flush after assembly. Furthermore, screws can be used to fix the outer ring 1 and the inner ring 2. Specifically, as Figure 8 and Fig. 9As shown, a plurality of inner ring fixing screw holes 1-4 are provided on the step groove 1-3, and a plurality of inner ring mounting holes 2-3 are correspondingly provided on the inner ring body 2-1. The positions of the inner ring fixing screw holes 1-4 and the inner ring mounting holes 2-3 correspond one to one. The inner ring 2 is fixed to the outer ring 1 by inner and outer ring fixing screws 4 that pass through the inner ring mounting holes 2-3 and are screwed into the inner ring fixing screw holes 1-4. The inner and outer rings are fixed by screws, and the connection is firm and reliable, and the assembly is simple and convenient. The inner and outer ring fixing screws 4 can be evenly arranged 3 to 6 in the circumferential direction to ensure the firmness of the connection between the inner and outer rings. The inner ring mounting holes 2-3 are preferably countersunk holes, and the inner and outer ring fixing screws 4 are also preferably countersunk screws, so that the inner and outer ring fixing screws 4 do not protrude from the end surface of the inner ring body 2-1 after installation. Further preferably, the outer contour of the inner ring body 2-1 and the outer contour of the step groove 1-3 are both circular, which is convenient for the processing and manufacturing of the inner and outer rings, and the assembly is more flexible.

[0045] like Figure 4 As shown, there is a gap s between the outer wall of the substrate of the LED light bar 3 and the inner wall of the outer ring 1, and the gap s is generally about 2 mm, which can ensure that the substrate of the LED light bar 3 does not contact the outer ring 1. In this embodiment, the outer ring 1 can be made of aluminum alloy material, and there is a gap between the outer wall of the substrate of the LED light bar 3 and the inner wall of the outer ring 1, which ensures that the LED light bar 3 does not contact the outer ring and cause a short circuit, thereby improving the working reliability of the signal directional display. Similarly, the inner ring 2 can also be made of aluminum alloy material, and the back of the substrate contacts the inner ring 2, and the two are insulated, and there will be no short circuit problem.

[0046] catch Figures 5 to 7 And refer to Fig. 9 and Fig.10 As shown, in this embodiment, a plurality of light bar fixing screw holes 2-2 are distributed at intervals in the circumferential direction of the inner ring 2, and a plurality of light bar mounting holes 3-2 are distributed at intervals along the length direction on the LED light bar 3. After the LED light bar 3 is wound on the outer wall of the inner ring 2, the light bar mounting holes 3-2 correspond to the positions of the corresponding light bar fixing screw holes 2-2. The LED light bar 3 is wound on the outer wall of the inner ring 2 and fixed to the inner ring 2 by a plurality of light bar fixing screws 5 that pass through the light bar mounting holes 3-2 and are screwed into the light bar fixing screw holes 2-2. The LED light bar 3 is fixed firmly by screws and is accurately positioned. The number of light bar mounting holes 3-2 on the LED light bar 3 can be determined according to its length. Generally, light bar fixing screws 5 need to be provided at both ends of the LED light bar 3 to prevent the ends of the LED light bar 3 from warping. In this embodiment, the positions of the light bar mounting hole 3-2 and the light bar fixing screw hole 2-2 are pre-designed, and the positions of the inner ring fixing screw hole 1-4 and the inner ring mounting hole 2-3 are also pre-designed. In this way, there is no need to specially adjust the angles of the inner and outer circles to ensure that each lamp bead 3-1 is in an aligned position with each light-transmitting hole 1-1, thereby improving the convenience of assembly.

[0047] The above-mentioned assembly structure solves the problem that the LED lamp beads are poorly assembled with the light-transmitting holes on the outer ring when they are distributed in a ring, and the cumulative assembly error easily causes the lamp beads to be difficult to align accurately with each light-transmitting hole. The LED light bar is installed with the inner ring to ensure the standard degree of the LED light bar to form a ring, so that each lamp bead is evenly distributed on the circumference. The inner ring and the outer ring are coaxially installed and fixed, so that the index angles of each lamp bead and the corresponding light-transmitting hole are equal, and the accurate alignment of the circularly distributed lamp beads with each light-transmitting hole is achieved, which greatly improves the assembly accuracy.

[0048] [Example 2]

[0049] This embodiment discloses a UAV signal directional display. Figure 1 and Figure 2 As shown, the UAV signal directional display comprises a light ring display component and a control module installed inside the light ring display component, wherein the light ring display component is used to display the signal position of the UAV, and the control module is used to receive the positioning signal of the UAV and control the light of the light ring display component. The light ring display component is assembled using the assembly structure of the UAV signal directional display of the above-mentioned embodiment 1, and the control module is electrically connected to the LED light bar 3, and is used to control the working state of each lamp bead 3-1 on the LED light bar 3 to display the direction of the UAV signal. Since the lamp beads 3-1 on the LED light bar 3 are evenly distributed within 360°, for example, 60 lamp beads 3-1 can be set in a circle in the circumferential direction, in this way, with the UAV signal directional display as the center, any direction can be indicated by the corresponding lamp bead 3-1. The control module is mainly composed of a signal receiving device and an LED light control device. The signal receiving device communicates wirelessly with the signal transmitting device of the unmanned aerial vehicle. The positioning signal of the unmanned aerial vehicle can be transmitted to the signal receiving device through the signal transmitting device. The signal receiving device feeds back the received positioning signal to the LED light control device. The LED light control device controls the lamp beads 3-1 in the corresponding direction to be always on or flash. In this way, ground operators can intuitively distinguish the location of the unmanned aerial vehicle by observing the lighting position of the lamp beads 3-1 on the signal directional display of the unmanned aerial vehicle, thereby improving the operational reliability of the unmanned aerial vehicle in an environment with poor visibility; at the same time, in the event of an accidental crash, the signal directional display can also be used to quickly lock the crash direction, providing convenience for the search of the unmanned aerial vehicle.

[0050] In this embodiment, at least one circle of light-transmitting holes 1-1 is provided on the outer ring 1, and at least one row of lamp beads 3-1 on the LED light bar 3 is provided accordingly, and each lamp bead 3-1 can be individually controlled by the control module, so that the lamp beads 3-1 in the corresponding position can be accurately controlled to light up. Preferably, three circles of light-transmitting holes 1-1 are provided up and down in the circumference of the outer ring 1, and three rows of lamp beads 3-1 on the LED light bar 3 are provided accordingly, and the colors displayed by the lamp beads 3-1 in each row can be different. Through the display of multiple rows of three-color LEDs, the displayed information is more intuitive. When working, the control module controls the lamp beads 3-1 on the LED light bar 3 corresponding to the direction of the unmanned aerial vehicle signal to be always on or flashing, and the lighting state of the lamp beads 3-1 on the LED light bar 3 changes with the change of the direction of the unmanned aerial vehicle signal.

[0051] As for the specific principle of the control module, it can be realized by existing communication technology and single chip control technology, and the required display effect or state can be realized only by programming technology. This part is not the improvement of the present invention, so it will not be elaborated here.

[0052] The present invention discloses an unmanned aerial vehicle signal directional display and its assembly structure. The LED light bar is installed in the inner circle, which ensures the standard degree of the LED light bar to form a circular ring, so that each lamp bead is evenly distributed on the circumference. The inner circle and the outer circle are coaxially installed and fixed, so that the index angles of each lamp bead and the corresponding light-transmitting hole are equal, and the lamp beads distributed on the circumference are accurately aligned with each light-transmitting hole, which greatly improves the assembly accuracy and satisfies the lighting display effect of the unmanned aerial vehicle signal directional display. The unmanned aerial vehicle signal directional display enables ground operators to intuitively grasp the position of the unmanned aerial vehicle in the air, and improves the operational reliability of the unmanned aerial vehicle in an environment with poor visibility; at the same time, in the event of an accidental crash, the signal directional display can also be used to quickly lock the crash direction, providing convenience for finding the unmanned aerial vehicle.

[0053] The present invention and its embodiments are described schematically above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and creatively designs a structure and an embodiment similar to the technical solution without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
