Description

Technical Field

[0001] This invention relates to the field of automotive driving simulator technology, specifically to a method for adjusting the height of a display screen in an automotive driving simulator. Background Technology

[0002] As an advanced virtual reality system, car simulators are designed to simulate a realistic driving experience and provide drivers with a safe and controllable training environment. This technology is widely used in driver training, automotive research and development, entertainment experiences, and other fields, and is gradually becoming an indispensable tool in the automotive and education sectors. The car driving simulator display screen is one of the key components, providing drivers with visual feedback and simulating the field of vision and environment during real driving.

[0003] In the existing technology, although car simulator displays provide high resolution and wide field of view, they lack synchronous and coordinated feedback with the driving simulator vehicle, which reduces the practicality and effectiveness of the simulated driving experience. Therefore, certain methods are needed to suppress stray light in order to improve the imaging quality and measurement accuracy of the optical system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for adjusting the height of a display screen in a car driving simulator, which solves the problem of lacking synchronous and coordinated feedback with the vehicle in the car simulator, thereby reducing the practicality and effectiveness of the simulated driving experience.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for a height-adjustable display screen in a car driving simulator includes the following steps: Step 1: Start the simulator, connect the car simulator to the curved display screen that shows the simulation screen, and perform a safety check on the car simulator to avoid potential safety hazards and ensure the safety of the driver using the simulator. Step 2: The driver rides in the car simulator and performs simulated driving. During the driving, the driver manipulates the car simulator to adjust its posture. The posture adjustment feedback is then reflected in the vehicle posture detection system, which collects the posture data of the car simulator. The vehicle posture detection system then outputs the posture data to the display screen controller. Based on the posture data, signals are transmitted to the electric guide rail and diaphragm metering pump to change the posture of the curved display screen in accordance with the posture changes of the car simulator. Step 3: When the rate of attitude change of the simulated vehicle is too frequent or the difference between the previous attitude change and the current attitude change is too large, the output signal value of the display controller is suppressed by the display attitude stabilization system. Step 4: After the simulated driving is completed, turn off the simulator and simultaneously operate the electric guide rail and diaphragm metering pump through the display controller to slowly adjust and reset the curved display screen.

[0006] Preferably, the specific steps for collecting the attitude data of the simulated car in step two are as follows: the attitude detection gyroscope synchronizes the attitude changes of the simulated car in real time and sends an electrical signal to the gyroscope attitude acquisition module. The gyroscope attitude acquisition module records and collects data every 0.05s to 0.1s and sends it to the display screen controller for synchronization processing.

[0007] Preferably, the specific steps for suppressing the output signal value in step three are as follows: S1. Set the attitude change rate threshold N times / s and set the difference threshold W between the previous attitude amplitude and the current attitude change amplitude. S2. The data monitoring module monitors in real time the frequency X times / second and the difference Y between the previous attitude amplitude and the current attitude change amplitude output by the display controller to the electric guide rail and diaphragm metering pump. S3. When either X > N or Y > W occurs, the attenuation value output module will immediately intercept and cancel the signal emitted by the display controller within 0.05s to 0.1s, and change the original command to reset the curved display screen at a slow speed.

[0008] Preferably, in step S3, if the display controller fails to stop transmitting for more than 0.1 seconds, the electric guide rail and diaphragm metering pump are immediately shut down to prevent accidents.

[0009] A height-adjustable display screen for a car driving simulator includes: The base has an offset disk rotatably connected to its top side. The offset disk can be raised and lowered by a lifting component. Electric guide rails are installed on both the left and right ends of the top side of the offset disk. A frame is connected to the adjacent side of the two electric guide rails by a torsion component. A curved display screen is installed on the front side of the frame. The curved display screen is curved. A stabilizing slide rail is fixedly connected to the rear end of the top side of the offset disk. A sliding seat is slidably connected to the outer wall of the stabilizing slide rail. The front side of the sliding seat is rotatably connected to the rear side of the frame to ensure the stability of the frame. As a car simulator for driving and maneuvering, the car simulator is equipped with a vehicle posture detection system, a display controller, and a display posture stabilization system. The display controller is electrically connected to the vehicle posture detection system and the display posture stabilization system.

[0010] Preferably, the lifting assembly includes four lifting airbags disposed inside the base, and two diaphragm metering pumps are installed at the internal terminal of the base. Both ends of the diaphragm metering pumps are connected to the lifting airbags through connecting pipes, and the top side of the lifting airbags abuts against the bottom side of the offset disk.

[0011] Preferably, the torsion assembly includes multiple ball shafts fixedly connected to the left and right sides of the frame, the outer wall of each ball shaft is fitted with a ball sleeve, and the ball sleeve is connected to the electric guide rail.

[0012] Preferably, the vehicle attitude detection system includes an attitude detection gyroscope and a gyroscope attitude acquisition module, and the attitude detection gyroscope and the gyroscope attitude acquisition module are electrically connected.

[0013] Preferably, the display screen attitude stabilization system includes a data monitoring module, an attenuation value calculation module, and an attenuation value output module. The data monitoring module, the attenuation value calculation module, and the attenuation value output module are electrically connected to each other, and the attenuation value output module is electrically connected to the display screen controller.

[0014] Preferably, the display screen controller is electrically connected to the electric guide rail and the diaphragm metering pump.

[0015] Working Principle: First, the simulator is started, connecting the simulated car and the curved display screen. A safety check is performed on the simulated car. After the check, the driver enters the simulated car for simulated driving. During driving, the driver manipulates the simulated car, causing adjustments to its posture. These adjustments are reflected in the vehicle posture detection system. The posture detection gyroscope synchronizes the vehicle's posture changes in real time and sends electrical signals to the gyroscope posture acquisition module. The gyroscope posture acquisition module records and acquires data every 0.05s to 0.1s, sending it to the display screen controller for synchronization. The vehicle posture detection system then outputs posture data to the display screen controller. Based on this data, signals are sent to the electric guide rail and diaphragm metering pump to change the posture of the curved display screen. To accommodate the changing posture of the simulated car, when the electric guide rail moves the ball sleeve connected to it, the ball shaft connected to the frame inside it is also moved, thus affecting the curved display screen mounted on the frame. If the electric guide rails on both sides move the ball sleeve synchronously, the curved display screen will move up and down stably, adjusting the height of the curved display screen, and the sliding seat on the rear of the frame will slide on the stable rail. If the electric guide rails on both sides do not move the ball sleeve synchronously, or if only one electric guide rail moves the ball sleeve in one direction, or if the electric guide rails on both sides move the ball sleeve in opposite directions, the ball sleeve will rotate on the surface of the ball shaft, causing the frame to change angle, and the rear side will rotate on the sliding seat. The curved display screen will change angle accordingly to adapt to the state of the simulated car. The top sides of the front and rear airbags are on the same horizontal plane. When the diaphragm metering pump delivers gas from one side of the front and rear airbags to the other side, the airbag on one side will inflate and lift up, while the airbag on the other side will collapse. This causes the originally horizontal offset disc to change angle, and together with the structure connected to the top side, including the curved display screen, it will tilt up or down, synchronizing with the posture of the car simulating the vehicle.

[0016] This invention provides a method for adjusting the height of a display screen in a car driving simulator. It has the following advantages: 1. This invention synchronizes the changes in the posture of the simulated car to the posture adjustment of the curved display screen in real time, allowing the driver to experience a more realistic driving experience when performing driving operations in the simulator, thus improving the practicality and effectiveness of the simulator in simulated driving experience.

[0017] 2. By setting a threshold for the rate of attitude change and a threshold for the difference in the magnitude of attitude change, the present invention enables the display screen attitude stabilization system to effectively control the speed and magnitude of the display screen's attitude adjustment, preventing the accuracy and comfort of simulated driving from being affected by excessively fast or large attitude changes.

[0020] 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.

[0021] Example: As part of this application, please refer to the appendix. Figure 1 - Appendix Figure 6 This invention provides a method for adjusting the height of a car driving simulator display screen, comprising the following steps: Step 1: Start the simulator, connect the car simulator 13 for simulated driving to the curved display screen 5 that displays the simulation screen, and perform a safety check on the car simulator 13 to avoid potential safety hazards and ensure the safety of the driver using the simulator. Step Two: The driver sits in the car simulation vehicle 13 and performs simulated driving. During the driving process, the driver manipulates the car simulation vehicle 13, and the posture adjustments fed back by the car simulation vehicle 13 are reflected in the vehicle posture detection system, collecting the posture data of the car simulation vehicle 13. The specific steps are as follows: The attitude detection gyroscope 15 synchronizes the attitude changes of the car simulation vehicle 13 in real time and sends an electrical signal to the gyroscope attitude acquisition module 16. The gyroscope attitude acquisition module 16 records and acquires data every 0.05s to 0.1s and sends it to the display screen controller 14 for synchronization processing. This enables the vehicle attitude detection system to output attitude data to the display screen controller 14. Based on the attitude data, the system sends signals to the electric guide rail 3 and the diaphragm metering pump 10 to change the attitude of the curved display screen 5 in order to match the attitude change of the car simulation vehicle 13. Step 3: When the attitude change rate of the simulated vehicle 13 is too frequent or the difference between the previous attitude change amplitude and the current preparatory attitude change amplitude is too large, the output signal value of the display controller 14 is suppressed by the display attitude stabilization system. The specific steps for suppression are as follows: S1. Set the attitude change rate threshold N times / s and set the difference threshold W between the previous attitude amplitude and the current attitude change amplitude. S2, the data monitoring module 17 monitors in real time the frequency X times / second and the difference Y between the previous attitude amplitude and the current attitude change amplitude output by the display screen controller 14 to the electric guide rail 3 and the diaphragm metering pump 10; S3. When either X > N or Y > W occurs, the attenuation value output module 19 will immediately intercept and cancel the signal emitted by the display controller 14 within 0.05s to 0.1s, and change the original command to reset the curved display screen 5 at a slow speed.

[0022] If the display controller 14 fails to stop sending for more than 0.1 seconds in S3, the electric guide rail 3 and the diaphragm metering pump 10 will be shut down immediately to avoid accidents. Step 4: After the simulated driving is completed, turn off the simulator and simultaneously operate the electric guide rail 3 and the diaphragm metering pump 10 through the display controller 14 to slowly adjust the curved display screen 5 to reset.

[0023] Based on the above-described method for adjusting the height of a car driving simulator display screen, as another aspect of this application, please refer to the appendix. Figure 1 - Appendix Figure 6 A height-adjustable display screen for a car driving simulator includes: The base 1 has an offset disk 2 rotatably connected to its top side. The top sides of the four lifting airbags 11 inside the base 1 abut against the bottom side of the offset disk 2. Two diaphragm metering pumps 10 are installed at the internal terminal of the base 1. Both ends of the diaphragm metering pumps 10 are connected to the lifting airbags 11 through connecting pipes 12. Electric guide rails 3 are installed on both the left and right sides of the top side of the offset disk 2. A frame 4 is connected to the adjacent side of the two electric guide rails 3. Ball sleeves 7 are fitted on the outer walls of multiple ball shafts 6 fixedly connected to the left and right sides of the frame 4. The ball sleeves 7 are connected to the electric guide rails 3. A curved display screen 5 is installed on the front side of the frame 4. The curved display screen 5 is curved. A stabilizing slide rail 8 is fixedly connected to the rear end of the top side of the offset disk 2. A sliding seat 9 is slidably connected to the outer wall of the stabilizing slide rail 8. The front side of the sliding seat 9 is rotatably connected to the rear side of the frame 4 to ensure the stability of the frame 4. Specifically, the surface of the curved display screen 5 is covered with a transparent anti-reflective film to reduce external glare and prevent the display content from being unclear when using the car simulator. When the electric guide rail 3 moves the ball sleeve 7 connected to it, the ball shaft 6, which is fitted inside and connected to the frame 4, is also moved, thus affecting the curved display screen 5 mounted on the frame 4. If the electric guide rails 3 on both sides move the ball sleeve 7 synchronously, the curved display screen 5 will move up and down stably, adjusting its height, and the sliding seat 9 on the rear side of the frame 4 will slide on the stable slide rail 8. If the electric guide rails 3 on both sides do not move the ball sleeve 7 synchronously, or if only one electric guide rail 3 moves the ball sleeve 7 in one direction, or if the electric guide rails 3 on both sides move the ball sleeve 7 in opposite directions, the ball sleeve 7 will rotate on the surface of the ball shaft 6, causing the frame 4 to change angle and rotate on the sliding seat 9 at the rear. The curved display screen 5 will change angle accordingly to match the state of the car simulator vehicle 13. The top sides of the front and rear airbags 11 are on the same horizontal plane. When the diaphragm metering pump 10 delivers gas from one side of the front and rear airbags 11 to the other side, the airbag 11 on one side will expand and lift up, while the airbag 11 on the other side will collapse. This will cause the originally horizontal offset disk 2 to change angle, and together with the structure connected to the top side, including the curved display screen 5, it will tilt up or down, synchronizing the posture of the car simulation vehicle 13.

[0024] Please refer to the appendix. Figure 4 - Appendix Figure 6The simulated car 13, used by the driver in a car simulator, has a simulation feedback function. Based on the driver's input, the simulated car 13 can produce movements such as shaking, vibration, and deviation. Internally, the simulated car 13 includes a vehicle attitude detection system, a display controller 14, and a display attitude stabilization system. The vehicle attitude detection system consists of an attitude detection gyroscope 15 and a gyroscope attitude acquisition module 16, which are electrically connected. The display attitude stabilization system consists of a data monitoring module 1... 7. The attenuation value calculation module 18 and the attenuation value output module 19 are composed of a data monitoring module 17, an attenuation value calculation module 18 and an attenuation value output module 19, an attenuation value output module 19 and a display screen controller 14, a display screen controller 14 and a vehicle posture detection system and a display screen posture stabilization system, and an electric guide rail 3 and a diaphragm metering pump 10. The display screen controller 14 outputs commands to the electric guide rail 3 and the diaphragm metering pump 10 to control the operation of the diaphragm metering pump 10 and the electric guide rails 3 at both ends.

[0025] 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.
