Description

Technical Field

[0001] The present invention relates to the technical field of drone performances, and in particular to a holographic display device and a usage method for a rotary-wing drone. Background Technique

[0002] With the increasing maturity of drone technology, using drones for performances has become a fresh and shocking performance method. A holographic display drone is to add a holographic display device to the drone, enabling the drone to play holographic images for performances.

[0003] Application No. 201822253578.4 discloses a holographic projection drone. The holographic projection drone includes: a drone body, a plurality of support legs installed on the drone body to support the drone body; a holographic projection unit fixed on the support legs; a display unit disposed above the holographic projection unit and close to the drone body, and the image displayed by the display unit is projected onto the holographic projection unit for display. This drone cannot adjust the orientation of the holographic projection unit to meet the viewing needs of audiences at various angles. At the same time, the holographic projection unit fixed on the drone is difficult to disassemble or install, and it is difficult to replace when the holographic projection unit is damaged. In view of these problems, a holographic display device that can be disassembled and installed portably and quickly and whose holographic imaging angle can be adjusted is designed. This device can be loaded and unloaded portably and quickly, and has a firm and stable structure. It can adjust the imaging direction angle by the signal output by the drone, greatly increasing the flexibility and maintainability of the performance, and has practical significance and a good application background. Summary of the Invention

[0004] The object of the present invention is to solve the shortcomings in the existing technology and propose a holographic display device and a usage method for a rotary-wing drone, including a drone body, an upper cover hook module, a loading and unloading connection module, an angle adjustment module, and a holographic display module.

[0005] The upper cover hook module includes a hook slot and a threaded hole. Four upper cover hook modules are respectively located at the four sides of the upper cover of the drone body, and are locked and fixed to the upper cover of the drone body by positioning screws passing through the threaded holes.

[0006] The loading and unloading connection module includes a top seat, a locking structure, and a latch. The top seat includes an upper top seat, a lower top seat, and a top seat connecting rod. The upper top seat and the lower top seat completely coincide in the horizontal direction, and the upper top seat and the lower top seat are connected vertically by the top seat connecting rod. The locking structure includes a limit housing, a large spring, a connecting rod, and a rotating rod. There is a circular through hole on the upper surface of the limit housing, and limit card slots on both sides. The connecting rod passes through the circular hole above the limit housing, and the square platform at the lower end of the connecting rod is located inside the limit housing. The cylinders at both ends of the square platform are stuck in the card slots on both sides of the limit housing, and the large spring is connected between the upper surface inside the limit housing and the square platform of the connecting rod. The upper end of the connecting rod is a hook, and the size of the hook of the connecting rod is exactly the same as the hook card slot of the upper cover hook module. The rotating rod fixes the short cylinder in the fixing holes on the four sides of the lower top seat and fixes the long cylinder in the fixing holes of the limit housing. One end of the latch is inserted into the fixing hole on the lower surface of the lower top seat.

[0007] The angle adjustment module includes a large motor, a short rod, a universal joint connecting shaft, a long rod, a small motor, and a rubber spring. The large motor is firmly connected to the top seat with four screws. The large motor is fitted with the short rod and can drive the short rod to rotate in the horizontal direction. The left and right shafts of the universal joint connecting shaft are firmly connected to the short rod, so that the short rod can drive the universal joint connecting shaft to rotate in the horizontal direction. The small motor is welded to the short rod, and the drill bit of the small motor is fitted and connected to the universal joint connecting shaft, so that the universal joint connecting shaft can rotate in the vertical direction. The front and rear shafts of the universal joint are firmly connected to the long rod, so that the universal joint connecting shaft drives the long rod to rotate in the vertical and horizontal directions. Four rubber springs are welded at the end of the long rod in a rectangular array to reduce the impact of the vibration of the drone during flight on the holographic imaging fan display.

[0008] The holographic display module includes an LED light bar and a protective washer. The LED light bar is connected to the rubber spring of the adjusting device and is driven to rotate by the angle adjustment module to achieve a shock-absorbing effect. The protective washer includes a washer, a connecting hoop, and a washer connecting rod. The washer and the connecting hoop are connected by the washer connecting rod. The connecting hoop is sleeved on the long rod of the angle adjustment module, so that the lower surface of the washer is located below the LED light bar. The connecting hoop is fixed on the long rod with a fastening screw, and the washer protects the LED light bar and acts as a drone tripod.

[0009] The usage method of a holographic display device for a rotor drone is as follows:

[0010] Step 1: Insert the hook of the connecting rod into the hook card slot, pull down the rotating rod to make the upper top seat close to the drone base, and then insert the other end of the latch into the latch card slot to make it fastened.

[0011] Step 2: Use the washer as a tripod and place the drone on a horizontal ground.

[0012] Step 3: Turn on the drone and make it fly to an appropriate height. The operator observes the imaging direction of the LED light bar in the holographic display module and outputs a signal to the angle adjustment module to control the angle of the holographic display module.

[0013] Step 4: The angle adjustment module turns on the large motor. Since the short rod is fitted with the rotating shaft of the large motor, the short rod rotates horizontally, driving the universal joint connecting shaft to rotate horizontally, and driving the long rod to rotate horizontally, so that the holographic display module faces an appropriate horizontal angle. The angle adjustment module turns on the small motor. Since the rotating shaft of the small motor is fitted and connected with the left and right two shafts of the universal joint connecting shaft, it drives the universal joint connecting shaft to rotate vertically, and drives the long rod to rotate vertically, so that the holographic display module faces an appropriate vertical angle.

[0014] Step 5: Turn on the LED light bar. Since the LED light bar is connected to the long rod by a rubber spring, the vibration generated by the rotation of the holographic imaging fan is reduced, which has an impact on the device. At the same time, the operator observes the display effect of the LED light bar in the holographic display module and adjusts the angle of the angle adjustment module in real time, so that the holographic display module always faces the audience. The drone can be moved during this period.

[0015] Step 6: After the performance, the drone inputs data to the angle adjustment module. The angle adjustment module turns on the small motor, driving the long rod to rotate vertically, so that the holographic display module is vertically downward. At this time, the washer in the protective washer is used as the footrest of the drone.

[0016] Step 7: After the drone lands on the ground, withdraw the lock from the lock slot and pull up the rotating rod. The connecting rod hook disengages from the hook slot, and the holographic display device of the rotor drone is removed.

[0017] The beneficial effects of the above technical solutions of the present invention are as follows:

[0018] (1) The holographic display device of the rotor drone greatly simplifies the installation and fixing process of the holographic display device by setting the loading and unloading connection module, significantly improves the operation convenience, reduces the downtime caused by drone maintenance, and can effectively prevent emergencies during the performance.

[0019] (2) The holographic display device of the rotor drone adjusts the imaging angle of the holographic display device by the operator controlling the angle adjustment module, so that the drone can move freely during the drone performance, and the holographic display module always faces the audience directly, avoiding the inability to move the drone due to the pseudo-holographic characteristics of the LED holographic imaging fan, increasing the flexibility of the performance and enriching the performance content.

[0034] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0035] As Figure 1 shown, a holographic display device and usage method of a rotary-wing UAV include a UAV body 1, an upper cover hook module 2, a loading and unloading connection module 3, an angle adjustment module 4, and a holographic display module 5.

[0036] As Figure 2 and 3 shown, the upper cover hook module 2 includes a threaded hole 2-1 and a hook slot 2-2. It is fixed on the four vertical faces of the upper cover of the UAV body 1 through fixing screws passing through the threaded hole 2-1.

[0037] As Figure 4 shown, the loading and unloading connection module 3 includes a top seat 3-1, a locking structure 3-2, and a lock 3-3. The top seat 3-1 includes an upper top seat 3-1-1, a top seat connecting rod 3-1-2, a lower top seat 3-1-3, a rotating rod bayonet 3-1-4, and a lock port 3-1-5 (see Figure 5 ). One end of the lock 3-3 directly passes through the lock port 3-1-5 to be connected to the top seat. The upper top seat 3-1-1 and the lower top seat 3-1-3 are connected by the top seat connecting rod 3-1-2 and completely coincide in the horizontal direction. The locking structure 3-2 includes a connecting rod hook 3-2-1, a limit housing 3-2-2, a large spring 3-2-3, a limit slot 3-2-4, a limit buckle 3-2-5, a rotating rod center axis 3-2-6, a rotating rod 3-2-7, a lock slot 3-2-8, and a connecting rod 3-2-9 (seeFigure 6 )。The top seat 3-1 is connected to the locking structure 3-2 by fitting the rotating rod bayonet 3-1-4 with the rotating rod central axis 3-2-6. The same applies to the other three sides. The connecting rod 3-2-9 passes through the limiting outer shell 3-2-2. The limiting buckle 3-2-5 is located inside the limiting outer shell 3-2-2 and passes through the limiting card slot 3-2-4 to play a limiting role. The connecting rod hook 3-2-1 is located outside the limiting outer shell 3-2-2. The large spring 3-2-3 is placed between the limiting buckle 3-2-5 and the inner upper surface of the limiting outer shell 3-2-2. When locking, embed the connecting rod hook 3-2-1 into the hook card slot 2-2 in the upper cover hook module to make them fully fit. Pull down the rotating rod 3-2-7 to make the upper top seat 3-1-1 close to the drone base, and then lock the other end of the lock 3-3 on the lock card slot 3-2-8 to make it fastened. The large spring 3-2-3 exerts a vertically downward elastic force on the square plane at the lower end of the connecting rod 3-2-9. The connecting rod 3-2-9 wants to move downward, so the connecting rod hook 3-2-1 exerts a vertically downward force on the hook card slot 2-2. The same applies to the other three locking structures 3-2. When the drone body 1 wants to move downward, at this time the drone base is close to the upper top seat 3-1-1, and the upper top seat 3-1-1 exerts a vertically upward supporting force on the drone body 1 to stably connect the drone body with this device. The large spring 3-2-3 has a locking function and can also alleviate the negative impact of the vibration caused by the drone flight on the stability of the locking device. As Figure 7 and Figure 8 shown, when locked, the other end of the lock 3-3 is stuck in the lock card slot 3-2-8 to prevent the rotating rod 3-2-7 from rotating due to the vibration of the drone flight, resulting in the disengagement of the connecting rod hook 3-2-1 from the hook card slot 2-2.

[0038] As Figure 9 shown, the angle adjustment module 4 includes a large motor 4-1, a short rod 4-2, a universal joint connecting shaft 4-3, a small motor 4-4, a long rod 4-5, and a rubber spring 4-6. As Figure 10 shown, the large motor 4-1 includes a large motor connecting device 4-1-1 and a large motor rotating shaft 4-1-2. The large motor connecting device 4-1-1 is fastened to the lower surface of the lower top seat 3-1-3 by fixing screws. The large motor rotating shaft 4-1-2 is fitted with the short rod 4-2 and can drive the short rod 4-2 to rotate in the horizontal direction. The left and right shafts of the universal joint connecting shaft 4-3 are fastened to the short rod 4-2, so that the short rod 4-2 can drive the universal joint connecting shaft 4-3 to rotate in the horizontal direction. As Figure 11As shown in the figure, the small motor 4-4 includes a small motor rotating shaft 4-4-1 and a small motor connecting device 4-4-2. By fixing the small motor connecting device 4-4-2 to the short rod 4-2 using fastening screws, the small motor 4-4 is fixed in place. The small motor rotating shaft 4-4-1 is fitted and connected to the universal joint connecting shaft 4-3, enabling the universal joint connecting shaft 4-3 to rotate in the vertical direction. The front and rear shafts of the universal joint connecting shaft 4-3 are tightly connected to the long rod 4-5, causing the universal joint connecting shaft 4-3 to drive the long rod 4-5 to rotate in the horizontal and vertical directions. Four rubber springs 4-6 are welded to the end of the long rod 4-5 in a rectangular array to mitigate the impact of the drone's flight vibration on the holographic display module.

[0039] As Figure 12 shown, the holographic display module 5 includes an LED light bar 5-1 and a protective washer 5-2. The other end of the rubber spring 4-6 is welded to the LED light bar 5-1, connecting the holographic display module 5 to the angle adjustment module 4 and also serving as a shock absorber. As Figure 13 shown, the protective washer 5-2 includes a connecting hoop 5-2-1, a washer connecting rod 5-2-2, and a washer 5-2-3. The connecting hoop 5-2-1 is fastened to the long rod 4-5 using fixing screws, positioning the lower surface of the washer 5-2-3 slightly below the lower surface of the LED light bar 5-1 to provide protection and also act as the drone's landing gear. Three washer connecting rods 5-2-2 are welded to the connecting hoop 5-2-1 and the washer 5-2-3.

[0040] The usage method of a holographic display device for a rotor drone is as follows:

[0041] Step 1: Insert the connecting rod hook 3-2-1 into the hook slot 2-2, pull down the rotating rod 3-2-7 to make the upper seat 3-1-1 closely adhere to the drone base, and then hook the other end of the lock 3-3 onto the lock slot 3-2-8 to fasten it.

[0042] Step 2: Use the washer 5-2-3 as the landing gear and place the drone on a horizontal ground.

[0043] Step 3: Turn on the drone and let it fly to an appropriate height. The operator observes the imaging direction of the LED light bar 5-1 in the holographic display module 5 and outputs a signal to the angle adjustment module 4 to control the angle of the holographic display module 5.

[0044] Step 4: The angle adjustment module 4 turns on the large motor 4-1. Since the short rod 4-2 is fitted with the rotating shaft 4-1-2 of the large motor, the short rod 4-2 rotates horizontally, driving the universal joint connecting shaft 4-3 to rotate horizontally, and driving the long rod 4-5 to rotate horizontally, so that the holographic display module 5 faces an appropriate horizontal angle. The angle adjustment module 4 turns on the small motor 4-4. Since the rotating shaft 4-4-1 of the small motor is fitted and connected with the left and right shafts of the universal joint connecting shaft 4-3, it drives the universal joint connecting shaft 4-3 to rotate vertically, driving the long rod 4-5 to rotate vertically, so that the holographic display module 5 faces an appropriate vertical angle.

[0045] Step 5: Turn on the LED light strip 5-1. Since the LED light strip 5-1 is connected to the long rod 4-5 by the rubber spring 4-6, the vibration generated by the rotation of the holographic imaging fan is reduced, which affects the device. At the same time, the operator observes the display effect of the LED light strip 5-1 in the holographic display module 5 and adjusts the angle of the angle adjustment module 4 in real time, so that the holographic display module 5 always faces the audience. The drone can be moved during this period.

[0046] Step 6: After the performance, the drone inputs data to the angle adjustment module. The angle adjustment module 4 turns on the small motor 4-4, driving the long rod 4-5 to rotate vertically, so that the holographic display module 5 faces vertically downward. At this time, the washer 5-2-3 in the protective washer 5-2 is used as the tripod of the drone.

[0047] Step 7: After the drone lands on the ground, withdraw the lock catch 3-3 from the lock catch slot 3-2-8 and pull up the rotating rod 3-2-7. The connecting rod hook 3-2-1 disengages from the hook slot 2-2, and the holographic display device of the rotor drone is removed.
