Description

Technical Field

[0001] This utility model relates to the field of driving simulator technology, and in particular to a driving simulator. Background Technology

[0002] With the rapid development of the automotive industry and the innovation of intelligent transportation technology, the demand for driving simulators in fields such as driver training, automotive R&D testing, and entertainment experiences is growing. In driver training scenarios, simulators can reduce the practical risks for novice learners and improve training efficiency. In automotive R&D, engineers use simulators to test vehicle handling performance and human-computer interaction systems. In the gaming and entertainment field, high-fidelity driving simulators have become the core equipment for immersive experiences. However, traditional driving simulators generally suffer from insufficient mechanical transmission precision and distorted operation feedback, making it impossible to accurately reproduce key experiences such as steering feel, pedal damping, and limit switches in real driving scenarios. This makes it difficult to meet the stringent requirements of modern professional training and high-end entertainment for high-fidelity simulators.

[0003] Existing driving simulators mainly consist of operating components and transmission mechanisms. The operating components include a steering wheel, pedal set, and gear shifting device, and are mostly made of plastic or metal to simulate the shape of real parts. The transmission mechanism usually uses a simple gear set or linkage mechanism to transmit operating signals, converting actions such as steering wheel rotation and pedal pressing into electrical signals.

[0004] However, existing driving simulators generally suffer from inaccurate steering simulation and distorted operation feedback, which greatly affects the effectiveness of driving training and experience. Traditional simulators rely on a single gear transmission for steering wheel transmission and lack precise angle detection and limiting devices, resulting in a large deviation between the steering angle and that of a real vehicle. This makes it difficult for trainees to develop correct steering habits during training. At the same time, due to the lack of a gravity adjustment device, the steering wheel operation resistance is constant, making it impossible to simulate the changes in steering damping under different vehicle speeds and road conditions, causing the driving experience to become disconnected from reality. Therefore, a driving simulator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a driving simulator, which aims to improve the problem that the steering wheel transmission of traditional simulators in the prior art relies on a single gear transmission and lacks accurate angle detection and limiting devices, resulting in a large deviation between the steering angle and the real vehicle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A driving simulator includes a base, a main unit head bracket on the base, an adjustment frame on the outer wall of the main unit head bracket, a bearing fixing plate connected to the adjustment frame, a gear one mounted on the bearing of the bearing fixing plate, a steering wheel connecting rod mounted on the upper end of the gear one, a steering wheel connected to the steering wheel connecting rod, a steering gravity adjustment device mounted on the lower end of the gear one, a gear two rotatably connected to one side of the gear one, a grating ring connected to one end of the gear two, a grating ring circuit board fixing frame next to the grating ring, and a limit component provided under the bearing fixing plate.

[0008] The limiting component includes a limiting groove, a guide rail box, and a positioning iron plate. The limiting groove is located at the bottom of the gear. The bottom of the guide rail box is fixedly connected to the bearing fixing iron plate. The flat part of the positioning iron plate is located inside the guide rail box, and the protruding part on one side of the positioning iron plate is inserted into the limiting groove.

[0009] As a further description of the above technical solution:

[0010] The main unit head bracket is covered by a head shell, and the head shell is provided with a mobile phone holder interface.

[0011] As a further description of the above technical solution:

[0012] The engine head housing is equipped with a protective housing for the light combination switch. The upper end of the protective housing for the light combination switch is provided with a strong magnet mounting position. When the steering wheel is rotated, a magnetic vortex effect is generated between the strong magnet in the strong magnet mounting position and the metal connecting rod, providing a stable damping force for the steering wheel rotation process.

[0013] The gear has an arc-shaped boss on its lower side, and a directional gravity adjustment device is installed inside the lower end of the boss. By tightening or loosening the screws on the directional gravity adjustment device, the gap between the arc-shaped boss and the bearing fixing plate can be adjusted. The smaller the gap, the greater the friction between the two, and the stronger the steering wheel rotation resistance; conversely, the larger the gap, the weaker the resistance, thus achieving precise control of the damping magnitude.

[0014] As a further description of the above technical solution:

[0015] One end of the gear is equipped with a grating ring, and a grating ring circuit board mounting bracket is fixedly connected next to the grating ring. A high-precision electronic sensor on the grating ring circuit board mounting bracket detects the rotation angle and position information of the steering wheel in real time through the grating ring.

[0016] As a further description of the above technical solution:

[0017] A gear shift seat is connected to one side of the base. The gear shift seat contains a gear shift box and a gear shift housing. One end of the gear shift seat is connected to the base via a hollow rotating shaft. The gear shift seat can rotate 360 ​​degrees around the base with the hollow rotating shaft as the fulcrum.

[0018] As a further description of the above technical solution:

[0019] The gear shift housing is equipped with a multi-function button, which is used to control the electronic parking brake, hazard lights, fog lights, or software screen view switching.

[0020] As a further description of the above technical solution:

[0021] The base has three U-shaped frames fixedly connected inside, and the clutch pedal, brake pedal and accelerator pedal are respectively installed inside the three U-shaped frames.

[0022] As a further description of the above technical solution:

[0023] A coil spring is provided between the three U-shaped brackets and the clutch pedal, brake pedal and accelerator pedal for automatic reset after the pedal is subjected to force.

[0024] This utility model has the following beneficial effects:

[0025] In this invention, the rotation of the steering wheel drives the connecting rod to rotate gear one. The meshing of gear one and gear two enables power transmission and angle conversion. Simultaneously, a grating ring is used to detect the rotation angle in real time. Combined with the sliding of the positioning iron plate in the limiting groove to trigger physical limiting, the strong magnet assembly position and the connecting rod work together to generate a magnetic vortex effect, providing stable damping force for the rotation process. These structures work together to achieve precise detection of the steering wheel angle, accurate limiting of the extreme position, and dynamic adjustment of the resistance feeling. This solves the problem of traditional simulators relying on a single gear transmission for steering wheel transmission, lacking precise angle detection and limiting devices, resulting in a large deviation between the steering angle and the real vehicle, inaccurate steering simulation, and distorted operation feedback, which affects the driving training and experience. This improves the training experience of the driving simulator. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-7This utility model provides an embodiment of a driving simulator, including a base 1, a main unit head bracket 2 mounted on the base 1, and an adjustment frame 13 on the outer wall of the main unit head bracket 2. The adjustment frame 13 can adjust the steering wheel tilt angle according to user needs to accommodate drivers of different body types and usage habits. A bearing fixing plate 24 is mounted on the adjustment frame 13, and a gear 15 is mounted on the bearing of the bearing fixing plate 24. The bottom surface of the gear 15 has an arc-shaped boss 26 and a limiting groove 22, and a connecting rod 14 is mounted on the upper end of the gear 15. The connecting rod 14 is connected to the steering wheel 23. Gear 15 is rotatably connected to gear 2 16 on one side. One end of gear 2 16 is connected to the grating ring 17. Next to the grating ring 17 is the grating ring circuit board fixing bracket 18. Gear 1 15 and gear 2 16 mesh with each other. The precise meshing of gear 1 15 and gear 2 16 enables the steering wheel 23 of the driving simulator to be adjusted smoothly and accurately, while avoiding excessive mechanical backlash or gear wear, ensuring stability under long-term use. The bearing fixing iron plate 24 is equipped with a limit component at the bottom.

[0037] The limiting component includes a guide box 20, a positioning iron plate 21, and a limiting groove 22. The bottom of the guide box 20 is fixedly locked onto the bearing fixing iron plate 24. The flat part of the positioning iron plate 21 is set inside the guide box 20. The limiting groove 22 is set on the bottom surface of the gear 15. The protruding part on one side of the positioning iron plate 21 is embedded in the limiting groove 22. When the steering wheel 23 is turned to the limit position of 3 turns, the positioning iron plate 21 will reach the beginning or end of the limiting groove 22. The limiting function is triggered by physical contact, preventing the steering wheel 23 from continuing to turn. The rotation range is precisely locked, simulating the steering limit of a real vehicle. Through this design, the driver can feel the real steering limit, which enhances the reliability of the simulator.

[0038] The machine head shell 11 is equipped with a mobile phone holder interface 27, which allows students to easily attach their mobile phones to the machine so that they can connect their mobile phones directly to the machine for practice without the need for a computer.

[0039] Inside the head unit housing 11 is a protective housing 12 for the light combination switch. The upper end of the protective housing 12 has three strong magnet mounting positions 25. When the steering wheel 23 is turned, it drives the metal connecting rod 14 to generate a magnetic vortex effect between the strong magnets, providing stable damping force for the steering wheel 23, simulating the resistance feel in real driving from an electromagnetic perspective. The lower end of the gear 15 is equipped with a steering gravity adjustment device 19. By tightening or loosening the screws on the steering gravity adjustment device 19, the friction between the arc boss 26 and the bearing fixing iron plate 24 is adjusted to adjust the steering wheel 23 rotation resistance. Therefore, this driving training machine has a dual system of magnetic vortex damping and friction damping working together, enabling the simulator to simulate the driving feel of different types of cars, which is closer to the real driving experience.

[0040] One end of gear 2 16 is equipped with a grating ring 17, and a grating ring circuit board mounting bracket 18 is fixed next to the grating ring 17. When the steering wheel 23 is rotated, it drives gear 1 15 to rotate through the connecting rod 14. Gear 1 15 then drives gear 2 16 and grating ring 17 to rotate. At this time, the high-precision electronic sensor on the grating ring circuit board mounting bracket can provide real-time feedback on the position information of the steering wheel 23 through the rotation of the grating ring, ensuring the precise control of the simulator and detecting the rotation angle and position information of the steering wheel 23.

[0041] A gear shift seat 3 is connected to one side of the base 1. The gear shift seat 3 and the base 1 are connected by a hollow rotating shaft. The gear shift seat 3 can rotate around the base 1, thus achieving the rotation and folding of the gear shift seat 3. The gear shift seat 3 is equipped with a gear box 4 and a gear housing 5. The gear housing 5 is equipped with a multi-function button 6. The multi-function button 6 is used to control the electronic handbrake, hazard lights, fog lights, or software screen view switching. Three U-shaped brackets 7 are fixedly connected inside the base 1. The clutch pedal 8, brake pedal 9, and accelerator pedal 10 are respectively installed inside the three U-shaped brackets 7. Coil springs are installed between the three U-shaped brackets 7 and the clutch pedal 8, brake pedal 9, and accelerator pedal 10 for automatic reset after the pedals are subjected to force. The pedals are suspended pedals, which are consistent with the pedal structure of most training vehicles on the market. They fundamentally restore the pedal feel and mechanical feedback of real driving. When training, students can not only feel the operating angle of the pedal naturally hanging down, but also accurately experience the same stroke resistance and rebound force as the real vehicle.

[0042] Working principle: When using this driving simulator, the main components are supported by the base 1. The driver can simulate the driving operation of a real vehicle by operating the steering wheel 23, clutch pedal 8, brake pedal 9, accelerator pedal 10, gear box 4, gear housing 5 and multi-function button 6 on the gear seat 3. When the driver turns the steering wheel 23, the connecting rod 14 drives the gear 15 to rotate. The gear 15 meshes with the gear 2 16 to realize power transmission and angle conversion, simulating the mechanical transmission of the steering wheel 23 of a real vehicle. The high-precision electronic sensor on the grating ring circuit board mounting bracket 18 detects the rotation angle and position information of the steering wheel 23 in real time through the grating ring on the upper end of the gear 2 16, providing accurate data for the driving simulation system to provide feedback on the vehicle's steering status.

[0043] As the steering wheel 23 rotates, it drives the limiting groove 22 on the gear 15 to make a circular motion. The limiting groove 22 drives the positioning iron piece 21 to slide linearly within the limiting groove 22. When the steering wheel 23 rotates to the limit position of 3 turns, the positioning iron piece 21 reaches the beginning or end of the limiting groove 22, and the physical contact triggers the limit, preventing the steering wheel 23 from rotating excessively, accurately locking the rotation range, and simulating the steering limit function of a real vehicle.

[0044] The upper part of the protective housing 12 of the light combination switch is provided with three strong magnet mounting positions 25. When the steering wheel 23 is turned, the metal connecting rod 14 and the strong magnets in the strong magnet mounting positions 25 generate a magnetic vortex effect, providing stable damping force for the turning of the steering wheel 23, simulating the resistance feel in real driving from an electromagnetic level. The lower end of the gear 15 is provided with a steering gravity adjustment device 19. A circular arc boss 26 is set below the gear 15. By tightening or loosening the three screws on the steering gravity adjustment device 19, the gap between the circular arc boss 26 and the bearing fixing iron plate 24 is adjusted. The smaller the gap, the greater the friction between the two, and the stronger the rotation resistance of the steering wheel 23; conversely, the larger the gap, the weaker the resistance. This achieves fine control of the damping of the steering wheel 23, allowing the driver to experience a steering feel similar to that of a real vehicle, enhancing the realism of the driving simulation.

[0045] The clutch pedal 8, brake pedal 9, and accelerator pedal 10 are respectively installed in three U-shaped frames 7. When the driver presses the pedal, the pedal rotates around the axis of the U-shaped frame 7 to realize the simulated operation of the vehicle's clutch, brake, and accelerator. The coil spring installed between the U-shaped frame 7 and the pedal provides a restoring force after the driver releases the pedal, so that the pedal automatically returns to its original position, simulating the rebound characteristics of a real pedal.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
