Description

Technical Field

[0001] This invention relates to the field of aircraft training technology, specifically to a VR real-scene flight training simulation device for unmanned aerial vehicles (UAVs). Background Technology

[0002] Aircraft are heavier-than-air flying vehicles that rely on aerodynamic principles to fly within the atmosphere. As an important branch, drones have been widely used in many fields, and the skill requirements for operators are gradually increasing. However, actual flight training is limited by factors such as venue, weather, and cost. VR real-scene simulation has become an important way to train efficiently.

[0003] Currently, while drone VR flight training devices can present flight scenarios through VR images, they lack a posture feedback mechanism that links with the virtual images. This results in the operator's perceived posture being out of sync with the VR images, causing dizziness for some sensitive individuals. Furthermore, it makes it difficult to establish a direct cognitive connection between hand control and flight posture, leading to slow learning and proficiency improvement during actual operation, thus affecting training effectiveness. Therefore, there is an urgent need to develop a drone VR real-scene flight training simulation device to solve these practical problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a VR real-scene flight training simulation device for drones, which solves the technical problem of lack of screen-linked attitude feedback during training simulation, resulting in asynchronous body sensation, dizziness, and difficulty in establishing a correlation between control and flight attitude.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drone VR real-scene flight training simulation device, comprising a mounting plate, and further comprising a training component, a simulation immersive experience mechanism, an automatic maintenance component, and a circulation component;

[0006] The training components include two sets of flight training simulation handles for users to hold and operate, a VR training helmet for users to wear to present VR reality, and a seat for sitting.

[0007] The simulated immersive experience mechanism includes two sets of shafts mounted on the top of the mounting plate. Connectors are movably mounted on the inner side of the shafts, and the top of the connectors is fixedly connected to a mounting base that is rotatably connected to the bottom of the seat. A second motor for driving the seat to rotate is fixedly connected to the center of the bottom of the mounting base. A mounting box is also fixedly connected to one side of the top of the mounting plate. A movable frame is slidably mounted on the top of the mounting box, and a support rod is rotatably mounted on the top of the movable frame. The top of the support rod is rotatably connected to one side of the bottom of the mounting base through a bearing bracket. A lead screw assembly for driving the movable frame to move horizontally is also provided inside the mounting box.

[0008] Preferably, the lead screw assembly includes a first motor disposed on one side of the mounting box. The output end of the first motor is fixedly connected through one side of the mounting box and is connected to a lead screw. A threaded sleeve is threadedly connected to the outer side of the lead screw, and the top of the threaded sleeve is fixedly connected to the bottom of the movable frame to drive the mounting seat to rotate in an arc around the top of the shaft frame, thereby adjusting the use angle of the seat during training.

[0009] Preferably, the automatic maintenance assembly includes a storage tank for storing lubricating oil, a delivery pump for pumping lubricating oil, and a telescopic tube for delivering lubricating oil to the inside of the threaded sleeve and directly to its connection with the lead screw thread.

[0010] Preferably, the storage box is installed on one side of the bottom of the mounting plate, the delivery pump is fixedly connected to one side of the storage box, and the oil inlet pipe of the delivery pump is connected through to the bottom of one side of the storage box. One end of the oil outlet pipe of the delivery pump is connected through to one end of the telescopic pipe, and the other end of the telescopic pipe extends into the interior of the mounting box and is connected through to one side of the threaded sleeve.

[0011] Preferably, the circulation assembly includes a collection tank for collecting lubricating oil, a delivery pipe for conveying the lubricating oil collected inside the collection tank, a filter box for transferring lubricating oil, and a nanoporous plate for filtering impurities inside the lubricating oil.

[0012] Preferably, the collection trough is fixedly connected to the bottom of the mounting box and is connected through the bottom of the mounting box. The conveying pipe is fixedly connected to one side of the bottom of the collection trough, and one end of the conveying pipe is fixedly connected to the top of one side of the filter box. The top of the filter box is fixedly connected to the bottom of the mounting plate. The nanoporous plate is fixedly connected to the inside of the filter box. A return oil pipe is fixedly connected to the bottom of one side of the filter box, and one end of the return oil pipe is connected through the top of one side of the storage box.

[0013] Preferably, a placement rack is fixedly connected to one side of the seat, and the VR training helmet is placed on top of the placement rack.

[0014] Preferably, the two sets of flight training simulation handles are located on the built-in armrests on both sides of the top of the seat, and the two sets of flight training simulation handles are aligned in the horizontal direction.

[0015] Preferably, the storage tank connected to the return oil pipe is the storage tank of the automatic maintenance component, and the connection point between the return oil pipe and the storage tank is located above the liquid surface in the storage tank.

[0016] This invention provides a VR-based real-scene flight training simulation device for unmanned aerial vehicles (UAVs). Compared with existing technologies, it has the following advantages:

[0017] 1. This device uses a second motor to rotate the seat, and a first motor to drive the lead screw, threaded sleeve, and linkage to move the frame and support rod. This allows the mounting base to adjust the seat angle around the shaft frame, enabling real-time linkage between the control, the device's usage posture, and the VR screen. This avoids dizziness and operational errors caused by the asynchronous posture and screen, and helps establish a memory association between actions and flight posture. This allows for quick mastery and improved proficiency when actually operating the drone.

[0018] 2. The delivery pump draws lubricating oil from the storage tank and delivers it to the connection between the threaded sleeve and the lead screw through the telescopic pipe. This provides continuous lubrication for frequently transmitted components, reduces dry friction and wear, prevents seat posture adjustment from getting stuck or producing abnormal noises during simulated training, ensures the long-term operation of core components, and ensures stable posture adjustment during long-term high-frequency use of the device, thus maintaining a sense of immersion in training.

[0019] 3. The lubricating oil flowing out of the threaded sleeve and lead screw is collected in the collection tank and sent to the filter box through the conveying pipe. After impurities are filtered out by the nanoporous plate, it is returned to the storage box for recycling due to the height difference. This not only avoids the waste of lubricating oil, but also solves the problem of oil stains and internal component contamination caused by random dripping of waste oil, and prevents failures caused by oil stains.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] First implementation method:

[0029] refer to Figure 1-4 A drone VR real-scene flight training simulation device includes a mounting plate 1, and also includes a training component, a simulation immersive experience mechanism 2, an automatic maintenance component 207, and a circulation component 3;

[0030] The training components include two sets of flight training simulation handles 6 for users to hold and operate, a VR training helmet 501 for users to wear to present VR reality, and a seat 402 for sitting.

[0031] The simulated immersive experience mechanism 2 includes two sets of shaft frames 201 set on the top of the mounting plate 1. A connector 202 is movably installed inside the shaft frame 201, and the top of the connector 202 is fixedly connected to the mounting base 4 which is rotatably connected to the bottom of the seat 402. The center of the bottom of the mounting base 4 is fixedly connected to a second motor 401 for driving the seat 402 to rotate. A mounting box 203 is also fixedly connected to one side of the top of the mounting plate 1. A movable frame 205 is slidably installed on the top of the mounting box 203, and a support rod 206 is rotatably installed on the top of the movable frame 205. The top of the support rod 206 is rotatably connected to one side of the bottom of the mounting base 4 through a bearing frame. A screw assembly 204 for driving the movable frame 205 to move in the horizontal direction is also provided inside the mounting box 203.

[0032] The lead screw assembly 204 includes a first motor 2041 disposed on one side of the mounting box 203. The output end of the first motor 2041 is fixedly passed through one side of the mounting box 203 and is connected to the lead screw 2042. A threaded sleeve 2043 is threadedly connected to the outside of the lead screw 2042, and the top of the threaded sleeve 2043 is fixedly connected to the bottom of the movable frame 205 to drive the mounting base 4 to rotate in an arc around the top of the shaft frame 201, thereby adjusting the use angle of the seat 402 during training.

[0033] The circulation assembly 3 includes a collection tank 301 for collecting lubricating oil, a delivery pipe 302 for conveying the lubricating oil collected inside the collection tank 301, a filter box 303 for transferring lubricating oil, and a nanoporous plate 304 for filtering impurities inside the lubricating oil.

[0034] A mounting bracket 5 is fixedly connected to one side of the seat 402, and the VR training helmet 501 is placed on top of the mounting bracket 5. Two sets of flight training simulation handles 6 are set on the built-in armrests on both sides of the top of the seat 402, and the two sets of flight training simulation handles 6 are aligned in the horizontal direction.

[0035] The working process of this embodiment is as follows:

[0036] Users sit in seat 402, wear VR training helmet 501 to obtain a simulated flight scene, and control the flight scene displayed on VR training helmet 501 by holding flight training simulation handle 6, thus achieving flight training interaction.

[0037] The second motor 401 drives the seat 402 to rotate. At the same time, the first motor 2041 drives the lead screw 2042 to rotate. The lead screw 2042 drives the threaded sleeve 2043 to move horizontally. The moving threaded sleeve 2043 drives the moving frame 205 to move synchronously. The moving frame 205 adjusts the mounting base 4 to move in an arc position through the support rod 206.

[0038] The movable mounting base 4 is restricted by the shaft frame 201 and the connector 202, allowing the mounting base 4 to move in an arc shape around the shaft frame 201 as the axis, thereby adjusting the usage angle of the seat 402. In conjunction with the second motor 401, the seat 402 is rotated for use, thus fitting the display screen of the VR training helmet 501. This achieves the function of real-time matching between the posture of the seat 402 and the virtual scene, avoiding the problem of dizziness and operational judgment errors caused by the asynchrony between posture and screen during the initial flight training of drones. It solves the problem that traditional static VR training relies solely on screen simulation and lacks real posture feedback, making it difficult for trainees to establish a connection between operational actions and flight posture, resulting in slow learning and slow improvement of operational proficiency when actually operating drones.

[0039] Second implementation method:

[0040] In existing applications of drone VR flight training devices, the transmission system's lead screw and threaded sleeve, due to high-frequency engagement for attitude adjustment, are prone to increased dry metal friction if lubrication is not timely, which shortens their lifespan and causes attitude adjustment jamming, mechanical noise, and interference with training continuity, destroying the VR immersion. The noise also affects the virtual auditory immersion. Therefore, this device is also designed with an automatic maintenance component, specifically as follows:

[0041] refer to Figure 6 In a second embodiment of the present invention, the automatic maintenance component 207 includes a storage tank 2073 for storing lubricating oil, a delivery pump 2071 for pumping lubricating oil, and a telescopic tube 2072 for delivering lubricating oil to the inside of the threaded sleeve 2043 and directly to its threaded connection with the lead screw 2042.

[0042] Storage tank 2073 is installed on one side of the bottom of mounting plate 1. Delivery pump 2071 is fixedly connected to one side of storage tank 2073, and the oil inlet pipe of delivery pump 2071 is connected to the bottom of one side of storage tank 2073. One end of oil outlet pipe of delivery pump 2071 is connected to one end of telescopic pipe 2072. The other end of telescopic pipe 2072 extends into the interior of mounting box 203 and is connected to one side of threaded sleeve 2043.

[0043] The delivery pump 2071 generates suction to draw the lubricating oil stored in the storage tank 2073 and deliver it to the telescopic pipe 2072. The telescopic pipe 2072 can then deliver the lubricating oil to the threaded connection between the threaded sleeve 2043 and the lead screw 2042.

[0044] Furthermore, the threaded sleeve 2043 and lead screw 2042 are automatically maintained, avoiding the increased wear and frictional resistance caused by the frequent adjustment of the threaded sleeve 2043 and lead screw 2042 to do work during flight simulation training. This achieves the function of long-term stable operation of the lead screw assembly 204, avoids jamming and abnormal noise during simulation training caused by insufficient lubrication of the components, and improves the stability of attitude adjustment during the immersion process of the device.

[0045] The third implementation method:

[0046] In existing applications of VR flight training devices for drones, after lubricating the transmission components of the device, the unabsorbed lubricating oil drips directly, which wastes resources, increases costs, and contaminates the outer shell of the device. To address this, this device is also designed with a circulation component, specifically as follows:

[0047] refer to Figure 5 , Figure 6In the third embodiment of the present invention, the collection tank 301 is fixedly connected to the bottom of the mounting box 203, and the collection tank 301 is connected through the bottom of the mounting box 203. The conveying pipe 302 is fixedly connected to one side of the bottom of the collection tank 301, and one end of the conveying pipe 302 is fixedly connected to the top of one side of the filter box 303. The top of the filter box 303 is fixedly connected to the bottom of the mounting plate 1. The nanoporous plate 304 is fixedly connected to the inside of the filter box 303. A return oil pipe is fixedly connected to the bottom of one side of the filter box 303, and one end of the return oil pipe is connected through the top of one side of the storage box 2073.

[0048] The storage tank 2073 connected to the return oil pipe is the storage tank 2073 of the automatic maintenance component 207, and the connection point between the return oil pipe and the storage tank 2073 is located above the liquid surface of the storage tank 2073.

[0049] The lubricating oil flowing out from the threads of the threaded sleeve 2043 and the lead screw 2042 drips into the collection tank 301, is collected through the collection tank 301, and is transported to the filter box 303 through the conveying pipe 302.

[0050] The nanoporous plate 304 inside the filter box 303 can filter impurities from the circulating lubricating oil. The filtered lubricating oil is then transported to the storage box 2073 through the return oil pipe by the height difference between the filter box 303 and the storage box 2073 for storage. This facilitates the circulation pump 2071 to pump the lubricating oil, realizing the function of reusing lubricating oil, avoiding lubricating oil waste, and solving the problems of equipment pollution and component oil accumulation caused by the random dripping of waste lubricating oil.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
