Description

Technical Field

[0001] The utility model relates to the field of aircraft simulator visual ball screens, in particular to an aircraft simulator visual ball screen device capable of realizing multi-viewing angle switching. Background Art

[0002] A flight simulator is a simulation device that can reproduce an aircraft and the air environment and can be operated. A simulator used to simulate aircraft flight is called an aircraft flight simulator. It usually consists of five parts: a simulated cockpit, a motion system, a visual system, a computer system, and an instructor console.

[0003] According to the public patent 202221456185.3, a flight simulator LED ball screen display system, it includes a shell, a steel frame and a ball screen from the outside to the inside, the ball screen includes a plurality of LED modules, and the plurality of LED modules form a sphere with an open bottom. A steel plate layer is arranged between the ball screen and the steel frame, and the outer side of the steel plate layer is fixedly connected to the steel frame, and the steel plate layer is detachably connected to the LED module. This application has the effect of increasing the overall visible visual range and improving the flight simulation training effect to a certain extent.

[0004] However, in the traditional aircraft simulator visual ball screen device, the multiple projectors set inside are installed in fixed positions. After these positions are set, they remain unchanged during the entire simulation process. Since the position of the projector is fixed, the projected image and viewing angle are also relatively fixed. Although this fixed projection method can provide a certain visual simulation effect, in the actual driving simulation process, when the driving simulation personnel need to quickly switch multiple angles, such as switching from the front view to the side view, or from the high-altitude view to the low-altitude view, due to the fixed position of the projector, the required new perspective image cannot be quickly obtained. This delay and limitation of perspective switching not only affects the realism and immersion of the driving simulation, but may also have a negative impact on the training and evaluation of the driving simulation personnel. For this reason, a new technical solution needs to be designed to solve it. Utility Model Content

This delay and limitation of perspective switching not only affects the realism and immersion of the driving simulation, but also may have a negative impact on the training and evaluation of the driving simulation personnel.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Embodiment 1: A visual spherical screen device for an aircraft simulator capable of realizing multi-view switching, see Figures 1 to 3, including a device frame 1 and a ball screen body 101, the ball screen body 101 is installed at the rear end of the device frame 1, one end of a six-axis mechanical arm 102 is installed on both sides of the bottom of the device frame 1, and the other end of the six-axis mechanical arm 102 is rotatably connected to a clamping head 2, and a projector switching component is arranged inside the clamping head 2. First, the six-axis mechanical arm 102 is connected to the gyroscope on the flight simulator seat in the cockpit. As a high-precision sensor, the gyroscope can capture various movements and posture changes of the seat during the simulated flight process, such as tilting and rotating, in real time, and convert these changes into electrical signal data. When the driving simulator needs to switch the viewing angle during the flight simulation process, the gyroscope will immediately capture the posture changes of the seat and transmit these data to the control system of the six-axis mechanical arm 102 in real time. After receiving the data from the gyroscope, the control system will quickly parse and process it to calculate the dual The position and angle of the projector need to be adjusted to ensure that the projected image can keep pace with the changes in the perspective of the driving simulator. Then, the six-axis robotic arm 102 uses its high flexibility and precise control capabilities to drive the dual projectors to rotate quickly and smoothly according to the instructions of the control system. During the rotation process, the joints of the robotic arm work together to ensure that the dual projectors can move according to the predetermined trajectory and speed while maintaining the stability and continuity of the projected image. Finally, when the dual projector rotates to the target position, it will stably project the new perspective image required by the driving simulator. The driving simulator can easily obtain views in all directions around the aircraft, whether it is the front, back, side, top or bottom. This all-round perspective switching capability greatly enhances the realism and immersion of the flight simulation and improves the training effect and experience of the driving simulator.

[0022] For details, see Figure 1 and Figure 2 The projector switching assembly includes a first motor 201 , a connecting rod body 303 , a mounting shell 205 , a projector body 204 , a square tube body 206 , and a limiting bolt 203 .

[0023] For further information, see Figure 2 The mounting shell 205 is located in the concave surface of the clamping head 2 , and sockets are provided on both sides of the mounting shell 205 . A square tube body 206 is inserted into the sockets, and the square tube body 206 extends into the mounting shell 205 .

[0024] It is worth noting that see Figure 2, one end of the square tube 206 extending out of the socket is connected to the projector body 204, and a plurality of screw holes are provided on the surface of the square tube 206, and the plurality of screw holes are threadedly connected with the limit bolts 203 passing through the mounting shell 205. When installing the dual projectors, the square tube 206 connected to the projector body 204 must first be inserted into the mounting shell 205, and then the limit bolts 203 are passed through the holes on the mounting shell 205 and connected with the screw holes on the outer surface of the square tube 206 to complete the installation and fixation of the dual projectors on the robotic arm. When it is necessary to perform synchronous heat dissipation of the dual projectors, the second motor 302 can be started. After the second motor 302 is started, it will drive the connecting rod 303 to start rotating. During the rotation of the connecting rod 303, it will drive the fan blades 304 to rotate together. The rotation of the fan blades 304 generates an airflow, which extracts the hot air discharged from the dual projectors through the square tube 206 into the external environment, thereby achieving heat dissipation of the dual projectors.

[0025] It is worth noting that see Figure 2 The first motor 201 is installed on the surface of the clamping head 2 , and one end of the first motor 201 is connected to a rotating column 202 . The rotating column 202 passes through the clamping head 2 and is fixed to the mounting shell 205 .

[0026] It is worth mentioning that see Figure 3 A second motor 302 is provided at both upper and lower ends of the mounting shell 205, one end of a support rod 3 is fixed on both sides of the second motor 302, the other end of the support rod 3 is fixed to the inner wall of the mounting shell 205, one end of the second motor 302 is connected to a connecting rod body 303, and a fan blade 304 is installed outside the connecting rod body 303.

[0027] It is worth emphasizing that see Figure 3 Both ends of the mounting shell 205 are provided with square holes 305 , and a partition net 301 is installed inside the square holes 305 .

[0028] It should be noted that the specific details of the control system are not described in detail in this application. The focus of this application is on the innovative proposal to combine a six-axis robotic arm, a gyroscope of a cockpit flight simulator seat, and a dual projector to achieve rapid rotation switching and projection of the flight simulator's viewing angles, rather than the control system itself.

[0029] As a supporting technology for realizing this innovative design, the basic principles and functions of the control system are generally understood within the knowledge of those skilled in the art. For example, the control system includes a sensor interface for receiving gyroscope data, a microprocessor or controller for processing data and issuing control instructions, a motor driver for driving the six-axis manipulator to move, and a second motor for controlling a cooling fan. The coordinated work of these components enables the entire system to operate according to a predetermined logic and process to achieve the required functions. Since these control technologies, sensor technologies, motor drive technologies, and heat dissipation technologies are mature and widely used in the art, there is no need to describe these prior arts in detail in this application. On the contrary, this application focuses more on explaining how to use these prior arts, combined with the innovative design of this application, to achieve rapid switching and multi-angle projection of the view angle of the flight simulator, thereby improving the realism and immersion of the flight simulator.

[0030] In summary, the control system in this application is implemented based on existing technologies, so it is not described in detail in this application. However, those skilled in the art can fully understand and apply these existing technologies to achieve the innovative functions and effects described in this application.

[0031] When using an aircraft simulator visual ball screen device that can realize multi-perspective switching, first, the six-axis mechanical arm 102 is connected to the gyroscope on the flight simulator seat in the cockpit. As a high-precision sensor, the gyroscope can capture various movements and posture changes of the seat during the simulated flight process, such as tilt, rotation, etc., in real time, and convert these changes into electrical signal data. When the driving simulation personnel needs to switch the perspective during the flight simulation, the gyroscope will immediately capture the posture changes of the seat and transmit these data to the control system of the six-axis mechanical arm 102 in real time. After receiving the data from the gyroscope, the control system will calculate the position and angle that the dual projectors need to adjust to ensure that the projected image can keep pace with the perspective changes of the driving simulation personnel. Then, the six-axis robot arm 102 drives the dual projectors to rotate quickly and smoothly according to the instructions of the control system, using its high flexibility and precise control ability. During the rotation process, the joints of the robot arm work together to ensure that the dual projectors can move according to the predetermined trajectory and speed while maintaining the stability and continuity of the projection image. Finally, when the dual projector rotates to the target position, it will stably project the new perspective image required by the driving simulator. The driving simulator can easily obtain views in all directions around the aircraft, whether it is the front, back, side, top or bottom. This all-round perspective switching capability greatly enhances the realism and immersion of the flight simulation and improves the training effect and experience of the driving simulator.
