Description

Technical Field

[0001] This utility model relates to the field of drone training technology, and in particular to a drone VR real-scene flight training simulation device. Background Technology

[0002] With the rapid development of drone technology, professional training has become a key link in ensuring the skill proficiency and safe flight of drone operators. Traditional drone flight training is often limited by natural conditions such as weather and location, and it is difficult to simulate complex and ever-changing flight environments, which to some extent limits the training effect. In order to overcome these limitations, an innovative drone VR real-scene flight training simulation device has emerged. It combines virtual reality technology with precise mechanical structure design to provide drone operators with a highly simulated, safe and controllable training platform.

[0003] A search revealed that this utility model, with announcement number CN222088182U, relates to the field of flight training technology and discloses a VR real-scene flight training simulation device for unmanned aerial vehicles (UAVs). However, it still has some shortcomings in actual use.

[0004] 1. In order to achieve the left-right and forward-backward swinging effects when the flight training simulator is in use, the device needs to be installed at the bottom of the entire seat, which occupies a large space and results in the length of each connecting component, thus increasing the manufacturing cost of the device.

[0005] 2. This flight simulator simulates the state of flight. Although the flight simulator has the effect of swinging left and right and forward and backward, the aircraft will vibrate when encountering airflow during actual flight. However, this device does not have the vibration function, so the simulation is relatively poor in terms of realism. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as large space occupation, long dimensions of connecting components, high manufacturing costs, and the lack of vibration function in the device when encountering airflow during actual flight, resulting in relatively poor simulation realism. Therefore, this invention proposes a VR real-scene flight training simulation device for unmanned aerial vehicles (UAVs).

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A VR real-scene flight training simulation device for drones includes a base, a base plate on top of the base, a seat fixedly connected to the top of the base plate, a lifting frame fixedly connected to the top of the base, a T-shaped frame passing through the lifting frame, the bottom end of the T-shaped frame sliding within the lifting frame, a rotating shaft passing through the T-shaped frame, two support frames fixedly sleeved on the outer wall of the rotating shaft, and the tops of the two support frames fixedly connected to the bottom of the base plate.

[0009] In one possible design, a cam is rotatably connected inside the lifting frame, and one end of the output shaft of the cam extends to one side of the lifting frame. A first drive motor is fixedly connected to the top of the base, and the output shaft of the first drive motor is fixedly connected to one end of the cam. The bottom of the T-shaped frame cooperates with the outer wall of the cam to drive the T-shaped frame to move up and down reciprocally. The bottom of the lifting frame is provided with a clearance groove, and the clearance groove provides rotation space for the cam.

[0010] In one possible design, a hollow sphere is provided inside the T-shaped frame. A sliding strip is fixedly connected to the bottom of the hollow sphere, which limits the sliding of the hollow sphere in the front-back direction within the T-shaped frame. The sliding strip slides within the T-shaped frame. A rack is fixedly connected to the top outer wall of the hollow sphere, and the rack slides within the T-shaped frame. A second gear is rotatably connected inside the T-shaped frame, and the second gear meshes with the rack. A second drive motor is fixedly installed inside the T-shaped frame, and one end of the output shaft of the second drive motor is fixedly connected to the second gear.

[0011] In one possible design, the T-shaped frame is equipped with a dual-axis drive motor. The output shafts at both ends of the dual-axis drive motor are fixedly connected to rotating rods. The two ends of the rotating shaft and the outer walls of the two rotating rods are all fixedly fitted with first gears. The four first gears are arranged in pairs, and the two first gears in the same pair mesh with each other. A connecting frame is rotatably fitted between the rotating shaft and the two rotating rods.

[0012] In one possible design, the T-shaped frame is provided with a swing groove, and the T-shaped frame is provided with two arc-shaped grooves with the hollow sphere as the center of rotation. The two arc-shaped grooves are located on both sides of the swing groove and are connected to the swing groove. The two sides of the dual-axis drive motor are fixedly connected with sliding rods, and the two sliding rods slide in the two arc-shaped grooves respectively.

[0013] In one possible design, a telescopic cover is fixedly connected between the base plate and the base.

[0014] In this application, the seat is placed on the ground for support. Based on the VR real-world flight state, when the seat adjusts its forward and backward angle, the output shafts of the dual-axis drive motors drive rotating rods at both ends. The rotating rods and the rotating shaft are connected by four first gears meshing in pairs, thus rotating the rotating shaft. The rotating shaft drives the support frame to rotate, thereby adjusting the forward and backward rotation angle of the seat above the T-shaped frame. Simultaneously, when the seat needs to be moved left or right, the second drive motor inside the T-shaped frame is activated. The output shaft of the second drive motor drives the second gear to rotate. The second gear meshes with a rack, causing the hollow sphere to adjust left and right within the T-shaped frame. The hollow sphere drives the rotating shaft for adjustment, and the rotating shaft drives the two support frames... The support frame connects to the base plate via two support frames, thereby enabling the base plate to adjust the seat. When the rotating shaft swings, the rotating shaft and the two rotating rods are connected by connecting frames. The two rotating rods are fixed to the two output shafts of the dual-axis drive motor. Two arc-shaped grooves are provided on both sides of the swing groove with a hollow sphere as the center. When the dual-axis drive motor swings, the sliding rods on both sides swing within the arc-shaped grooves. When the seat needs to bounce up and down, the first drive motor is activated, and the output shaft of the first drive motor drives the cam to rotate. The T-shaped frame presses on the cam, and the rotation of the cam causes the T-shaped frame to bounce up and down. When the seat moves forward, backward, or up and down, the telescopic cover can retract and unfold to make room.

[0015] Beneficial effects: In this utility model, the drone VR real-scene flight training simulation device is connected to the T-shaped frame and two support frames at the bottom of the device through a rotating shaft to achieve overall support. The device only needs two support frames on both sides of the T-shaped frame to achieve the effect of supporting the base plate, so that the device does not occupy the entire space under the seat, making the device compact and greatly reducing the manufacturing cost of the device.

[0016] In this utility model, the drone VR real-scene flight training simulation device pushes the T-shaped frame to move up and down within the lifting frame by rotating the cam, so that the seat can achieve the effect of up and down bumping during the up and down movement of the T-shaped frame.

[0017] This invention has multiple beneficial effects, such as flexible simulation adjustment, stable structure, strong adaptability, easy maintenance, and improved training efficiency and experience. The T-shaped frame is located between the two support frames and serves as the main support, making the space occupied by the bottom support of the device smaller. It is an innovative and practical device in the field of UAV flight training. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figure 1 and Figure 2 A simulation device includes a base 2, a base plate 4 on top of the base 2, a seat 1 fixedly connected to the top of the base plate 4, a lifting frame 5 fixedly connected to the top of the base 2, a T-shaped frame 6 passing through the lifting frame 5, and the bottom end of the T-shaped frame 6 sliding within the lifting frame 5. A rotating shaft 9 passes through the T-shaped frame 6, and two support frames 7 are fixedly fitted on the outer wall of the rotating shaft 9, with the tops of the two support frames 7 fixedly connected to the bottom of the base plate 4. The base 2 is used to place on the ground, and the base plate 4 above the base 2 is used to connect the seat 1 for the trainee to sit on. The lifting frame 5 is located between the base 2 and the base plate 4, and the T-shaped frame 6 passes through the lifting frame 5, raising the sliding space of the bottom end of the T-shaped frame 6 in the vertical direction. At the same time, the rotating shaft 9 passes through the T-shaped frame 6 and is connected to the base plate 4 through the support frames 7 at both ends of the rotating shaft 9, so that when the rotating shaft 9 rotates, it causes the seat 1 to rotate back and forth at a certain angle.

[0025] Reference Figure 4A cam 20 is rotatably connected inside the lifting frame 5, and one end of the output shaft of the cam 20 extends to one side of the lifting frame 5. A first drive motor 14 is fixedly connected to the top of the base 2, and the output shaft of the first drive motor 14 is fixedly connected to one end of the cam 20. The bottom of the T-shaped frame 6 cooperates with the outer wall of the cam 20 to drive the T-shaped frame 6 to move up and down reciprocally. The bottom of the lifting frame 5 is provided with a relief groove 12, which provides rotation space for the cam 20. The first drive motor 14 drives the cam 20 to rotate. When the cam 20 rotates, its outer wall pushes the T-shaped frame 6 to slide up and down inside the lifting frame 5, thereby realizing the lifting motion. The bottom of the lifting frame 5 is provided with a relief groove 12 to provide rotation space for the cam 20.

[0026] Reference Figure 3 A hollow sphere 8 is housed within a T-shaped frame 6. A sliding strip is fixedly connected to the bottom of the hollow sphere 8, limiting its forward and backward movement within the T-shaped frame 6. A rack 17 is fixedly connected to the top outer wall of the hollow sphere 8, and slides within the T-shaped frame 6. A second gear 16 is rotatably connected within the T-shaped frame 6, meshing with the rack 17. A second drive motor is fixedly installed within the T-shaped frame 6, with one end of its output shaft fixedly connected to the second gear 16. The second drive motor drives the second gear 16 to rotate, thereby causing the rack 17 and the hollow sphere 8 to swing left and right within the T-shaped frame 6.

[0027] Reference Figure 2 and Figure 3 The T-shaped frame 6 is equipped with a dual-axis drive motor 18. Both output shafts of the dual-axis drive motor 18 are fixedly connected to rotating rods 10. First gears 11 are fixedly fitted onto both ends of the rotating shaft 9 and the outer walls of the two rotating rods 10. The four first gears 11 are arranged in pairs, with the two first gears 11 in the same pair meshing. Connecting frames 15 are rotatably fitted between the rotating shaft 9 and the two rotating rods 10. The dual-axis drive motor 18 drives the two rotating rods 10 to rotate. The two rotating rods 10 mesh with the rotating shaft 9 through the first gears 11, thereby causing the rotating shaft 9 and the support frame 7 to rotate.

[0028] Reference Figure 3The T-shaped frame 6 has a swing groove 13 inside, and two arc-shaped grooves with the hollow sphere 8 as the center of rotation inside the T-shaped frame 6. The two arc-shaped grooves are located on both sides of the swing groove 13 and are connected to the swing groove 13. The two sides of the dual-axis drive motor 18 are fixedly connected to sliding rods 19, and the two sliding rods 19 slide in the two arc-shaped grooves respectively. When the dual-axis drive motor 18 is working, the sliding rods 19 slide in the arc-shaped grooves, limiting the swing range of the dual-axis drive motor 18, while ensuring that the dual-axis drive motor 18 can smoothly drive the rotating rod 10 and the rotating shaft 9 to perform a flipping motion.

[0029] This application can be used in the field of drone flight training, or in other fields applicable to this application.

[0030] Example 2: Reference Figure 2 An improvement upon Embodiment 1: A VR real-scene flight training simulation device for unmanned aerial vehicles (UAVs) is applied to the field of UAV flight training. A telescopic cover 3 is fixedly connected between the base plate 4 and the base 2. The telescopic cover 3 can extend, retract, and deform according to the lifting and tilting movements of the base plate 4, thereby protecting the trainee from external interference and improving the overall aesthetics and practicality of the simulation device.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the first drive motor 14 and the dual-axis drive motor 18 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
