Description

Technical Field

[0001] This invention relates to the field of driving simulator gear shift simulation technology, and more particularly to a vehicle driving simulator gear shift simulation device. 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. A car driving simulator's gear shifting device typically refers to the ability to seamlessly switch between manual and automatic transmissions within the simulator, simulating the gear shifting experience in real driving.

[0003] A search revealed a Chinese patent publication number CN112687152B, which discloses a vehicle driving simulator gear shifting device. This device only requires one gear shift lever, and by changing the gear shift slot, it can achieve multiple gear shifts, greatly simplifying the structure and reducing the size. It can simulate the gear shifting control structure of various large, medium and small cars. However, the above technical solution can only simulate gear shifting for manual transmissions, and cannot allow the gear shift simulator to quickly switch between manual and automatic gear shifting according to the student's learning needs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vehicle driving simulator gear shifting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vehicle driving simulator gear shifting device includes a mounting box. A top cover is fixed to the outer wall of the mounting box. A gear shifting guide groove is opened on the outer wall of the top cover. Rotary shafts are rotatably connected to the inner walls on both sides of the mounting box. Rotary frames are fixed to the outer walls of the rotating shafts. Rotary rods are rotatably connected to the inner walls on both sides of the rotating frames via damping bearings. A simulated gear lever is fixed to the outer wall of the rotating rod. The outer wall of the simulated gear lever is slidably connected to the inner wall of the gear shifting guide groove. Left and right gear shifting clutch simulation mechanisms are provided on the rotating shaft and the inner wall of the mounting box. Front and rear gear shifting clutch simulation mechanisms are provided on the outer walls of the rotating frame and the rotating rod.

[0006] Preferably, the outer wall of the mounting box is fixed with a mounting plate, and the outer wall of the mounting plate is rotatably connected to a clutch simulation pedal via a hinge.

[0007] Furthermore: one end of the rotating rod passes through the outer wall of one side of the rotating frame, and the other end of the rotating rod is connected to a telescopic rod through a universal coupling. The telescopic end of the telescopic rod is fixed with a gear.

[0009] As a preferred embodiment of the present invention: a plurality of conductive plates corresponding to the simulated gear positions of the simulated lever are provided on the inner wall of one side of the mounting box; an elastic metal plate is fixed on the outer wall of the second toothed plate; a conductive connector is provided on one side of the elastic metal plate in close contact with the inner wall of the mounting box; a control panel is provided on the outer wall of the mounting box; and the conductive plates and conductive connectors are electrically connected to the control panel respectively.

[0010] As a further preferred embodiment of the present invention: the left and right gear adjustment clutch simulation mechanism includes a support frame, a first cylinder, a first tension spring, a push plate, a pull plate, a first friction band, an electrically controlled multi-way valve, and a friction ring. The electrically controlled multi-way valve is fixed to the bottom inner wall of the mounting box and is connected to the first airbag through an air guide pipe. The support frame is fixed to the bottom outer wall of the mounting box. The first cylinder and the first tension spring are respectively fixed to the top outer wall of the support frame. The bottom outer wall of the push plate is fixed to the output end of the first cylinder and the top outer wall of the first tension spring. A set of pull plates is fixed to the top outer wall of the push plate. The two ends of the first friction band are respectively fixed to the top outer wall of the pull plate. The friction ring is fixed to the outer wall of the rotating shaft. The first friction band is sleeved on the outer wall of the friction ring. The input end of the first cylinder is connected to the electrically controlled multi-way valve through an air guide pipe. The electrically controlled multi-way valve is electrically connected to the control panel.

[0011] As a further embodiment of the present invention: the front and rear gear adjustment clutch simulation mechanism includes a mounting slot, a second cylinder, a three-way valve, a movable frame, a second tension spring, and a second friction band. The mounting slot is opened on the outer wall of the rotating frame. The second cylinder is fixed on the inner wall of the mounting slot. The input end of the second cylinder is connected to the three-way valve. The three-way valve is connected to the electronically controlled multi-way valve through an air guide pipe. The movable frame is fixed on the output end of the second cylinder. The second friction band is fixed on the top outer wall of the movable frame and is sleeved on the outer wall of the rotating rod. The second tension spring is fixed on the bottom outer wall of the movable frame, and the bottom end of the second tension spring is fixed on the outer wall of the rotating frame.

[0012] Based on the aforementioned scheme: the automatic transmission switching mechanism includes a push plate, a connecting rod, a control button, a movable column, a second airbag, a first cross-shaped guide groove, an inclined groove, and a second cross-shaped guide groove. The control button is located on the top outer wall of the top cover and is electrically connected to the control panel. The second cross-shaped guide groove and the first cross-shaped guide groove are respectively opened on both sides of the middle channel of the gear adjustment guide groove. The movable column is slidably connected to the inner walls of the second cross-shaped guide groove and the first cross-shaped guide groove. The second airbag is located on the inner wall of the first cross-shaped guide groove and is connected to a three-way valve through an air guide pipe. The connecting rod is fixed to the top outer wall of the movable column, and the push plate is fixed to the outer wall of the connecting rod. The control button is electrically connected to the control panel. The inclined groove is opened on one side of the push plate opposite to the control button, and the height of the inclined groove is greater than or equal to the height of the control button.

[0013] A preferred embodiment based on the aforementioned scheme is as follows: the outer wall of the mounting plate is provided with a brake simulation pedal and an accelerator simulation pedal, and the brake simulation pedal and the accelerator simulation pedal are electrically connected to the control panel respectively.

[0014] The beneficial effects of this invention are as follows: 1. This solution incorporates an automatic transmission switching mechanism, enabling rapid switching between manual and automatic simulation. Users can activate the automatic transmission simulation mode by pushing the push plate and pressing the control button. At this time, the movable column blocks the lateral opening of the gear guide groove, restricting the gear lever movement to the central straight track. Simultaneously, this operation unlocks the front and rear gear adjustment clutch mechanism via pneumatic transmission, allowing the gear lever to move only forward and backward, simulating the P, R, N, and D gears of an automatic transmission. To switch back to manual mode, simply press the button again, and the mechanism will automatically reset. This solves the problem of existing technologies being unable to simultaneously simulate two shifting modes on the same device, allowing a single simulator to adapt to both manual and automatic transmission simulation training and the needs of trainees at different training stages, greatly expanding its applicability.

[0015] 2. This solution replicates the shifting logic of a manual transmission car through a mechanical and pneumatic linkage design. The two sets of clutch simulation mechanisms, one for left and right, and one for front and rear, are driven by the air pressure generated by pressing the clutch simulation pedal. When the pedal is pressed, the air pressure drives the cylinder to disengage the friction band from the corresponding friction ring or lever, releasing the rotational restrictions on the pivot (controlling left and right gear selection) and the lever (controlling front and rear gear shifting). This then pushes the gear lever to shift gears. After releasing the pedal, the mechanism resets under the action of the tension spring, the friction band re-clamps, and the gear is locked. This complete force feedback process of "clutch depressing - gear shifting - clutch releasing" simulates the clutch working logic of a real vehicle, effectively enhancing the realism and immersion of driving training.

[0016] 3. This solution utilizes a detection system that combines mechanical transmission and electrical contact. The left and right movement of the gear lever (gear selection) is achieved through the engagement of a gear plate with the first gear plate, which in turn moves the entire guide frame and the second gear plate up and down. The forward and backward movement of the gear lever (gear engagement) is achieved through the engagement of a gear with the second gear plate, which in turn moves the second gear plate forward and backward. The elastic metal sheet and its conductive connector integrated on the second gear plate move in tandem with the forward, backward, left, and right rotation of the gear lever, accurately contacting the conductive sheets installed on the inner wall of the housing corresponding to different gear positions. This method of combining pure mechanical positioning with electrical contact signals is structurally reliable, avoids the problem of sensor susceptibility to interference, and ensures that each gear shift accurately triggers the corresponding electrical signal, providing precise gear input for the driving simulation software.

[0017] 4. In automatic mode, the electronically controlled multi-way valve closes, preventing the clutch pedal from being depressed. This physically prevents accidental operation by the user and clearly indicates that the system is in automatic mode. These designs lower the learning threshold for students, allowing both instructors and students to quickly get started and focus on driving skills training itself, thereby effectively improving the safety and efficiency of training.

Detailed Implementation

[0020] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Example 1: A vehicle driving simulator gear shifting device, such as Figure 1-6 As shown, the device includes a mounting box 1. A top cover 13 is fixed to the outer wall of the top of the mounting box 1. A gear adjustment guide groove 11 is opened on the outer wall of the top cover 13. A rotating shaft 15 is rotatably connected to the inner walls on both sides of the mounting box 1. A rotating frame 22 is fixed to the outer wall of the rotating shaft 15. A rotating rod 34 is rotatably connected to the inner walls on both sides of the rotating frame 22 through damping bearings. A simulated gear lever 10 is fixed to the outer wall of the rotating rod 34. The outer wall of the simulated gear lever 10 is slidably connected to the inner wall of the gear adjustment guide groove 11. A left and right gear adjustment clutch simulation mechanism is provided on the rotating shaft 15 and the inner wall of the mounting box 1. A front and rear gear adjustment clutch simulation mechanism is provided on the outer wall of the rotating frame 22 and the rotating rod 34. An automatic gear switching mechanism is provided on the outer wall of the top cover 13. The mounting box 1 has a mounting plate 2 fixed on its outer wall. The outer wall of the mounting plate 2 is connected to a clutch simulation pedal 3 via a hinge. A first airbag 4 is fixed between the clutch simulation pedal 3 and the mounting plate 2. The first airbag 4 is connected to the left and right gear adjustment clutch simulation mechanism and the front and rear gear adjustment clutch simulation mechanism via air guide pipes.

[0023] One end of the rotating rod 34 passes through the outer wall of one side of the rotating frame 22, and one end of the rotating rod 34 is connected to the telescopic rod 32 through the universal coupling 33. The telescopic end of the telescopic rod 32 is fixed with a gear 35. A set of guide rails 17 is fixed to one inner wall of the mounting box 1. A set of first toothed plates 28 are slidably connected to the outer wall of the guide rails 17. A set of toothed discs 27 are fixed to the outer wall of the rotating shaft 15. The toothed discs 27 are meshed with the first toothed plates 28. An L-shaped connecting plate 29 is fixed to the outer wall of the two first toothed plates 28 on opposite sides. The telescopic end of the telescopic rod 32 is rotatably connected to the outer wall of one side of the L-shaped connecting plate 29. A guide frame 30 is fixed to the outer wall of the L-shaped connecting plate 29. A second toothed plate 31 is slidably connected to the inner wall of the guide frame 30. A gear 35 is meshed with the second toothed plate 31. The inner wall of one side of the mounting box 1 is provided with a plurality of conductive sheets 14 corresponding to the simulated positions of the simulated lever 10. An elastic metal sheet 37 is fixed on the outer wall of the second toothed plate 31. A conductive connector 38 is provided on one side of the elastic metal sheet 37 in close contact with the inner wall of the mounting box 1. A control panel is provided on the outer wall of the mounting box 1. The conductive sheets 14 and the conductive connector 38 are electrically connected to the control panel respectively. The left and right gear adjustment clutch simulation mechanism and the front and rear gear adjustment clutch simulation mechanism can limit the rotating shaft 15 rotatably connected to the inner wall of the mounting box 1 and the rotating rod 34 rotatably connected to the inner wall of the rotating frame 22 respectively when the user does not press the clutch simulation pedal 3, so that the user cannot adjust the gear by pushing the simulated gear lever 10 in the front, back, left and right when the user does not press the clutch simulation pedal 3. When the user presses the clutch simulation pedal 3, the clutch simulation pedal 3 will pressurize the first airbag 4, and the gas inside the first airbag 4 will fill the left and right gear adjustment clutch simulation mechanism and the front and rear gear adjustment clutch simulation mechanism. This will drive these two mechanisms to release the restriction on the rotating shaft 15 and the rotating rod 34, so that the user can push the simulated gear lever 10 to switch gears in all directions after pressing the clutch simulation pedal 3, thereby simulating the gear shifting operation environment of a manual transmission. When practicing automatic gear shifting, first push the simulated gear lever 10 to the center of the gear shifting guide groove 11. Then push the automatic gear shifting mechanism forward. The automatic gear shifting mechanism will limit the simulated gear lever 10 to the middle of the gear shifting guide groove 11, allowing the simulated gear lever 10 to be pushed back and forth only under the guidance of the middle of the gear shifting guide groove 11. When pushing the automatic gear shifting mechanism forward, the front and rear gear shifting clutch simulation mechanism will also be pushed to release the restriction on the rotating lever 34, allowing the user to push the simulated gear lever 10 to rotate back and forth and practice the D, N, and R gears of the automatic transmission. This allows the gear shifting simulation device to quickly switch between automatic and manual gear shifting simulations, improving the applicability and functionality of the gear shifting simulation device.

[0024] When the user pushes the simulated gear lever 10 to rotate back and forth under the guidance of the rotating rod 34, the rotating rod 34 will drive the telescopic rod 32 on one side to rotate together with the rotating rod 34 through the universal coupling 33, thereby driving the gear 35 to push the second toothed plate 31 meshing with it to move back and forth a corresponding distance under the guidance of the guide frame 30, so that the conductive connector 38 on the outer wall of the elastic metal sheet 37 can move to the corresponding conductive sheet 14 that marks the corresponding gear position according to the angle of the rotation of the rotating rod 34. When the user pushes the simulated gear lever 10 to rotate left and right under the guidance of the rotating shaft 15, the gear plate 27 on the outer wall of the rotating shaft 15 will push the first gear plate 28, which meshes with it, to move up and down a corresponding distance under the guidance of the guide rail 17. This allows the second gear plate 31 to move up and down a corresponding distance along with the L-shaped connecting plate 29, so that the conductive connector 38 can follow the left and right swaying of the simulated gear lever 10 to switch to the conductive plate 14 side corresponding to the first / second, third / fourth, and fifth / reverse gears of the manual gear. Then, by pushing the simulated gear lever 10 back and forth, the conductive connector 38 can be moved to the conductive plate 14 marked with the corresponding manual gear. After the conductive connector 38 is connected to the conductive plate 14 marked with the corresponding gear, the control panel receives the corresponding electrical signal and controls the vehicle driving simulator to simulate the vehicle speed in the corresponding gear, thus accurately simulating the manual gear adjustment.

[0025] When the user shifts gears and releases the clutch simulation pedal 3, the left and right gear adjustment clutch simulation mechanism and the front and rear gear adjustment clutch simulation mechanism will re-limit the rotating shaft 15 and the rotating rod 34.

[0026] like Figure 1-4 As shown, the left and right gear shifting clutch simulation mechanism includes a support frame 19, a first cylinder 18, a first tension spring 23, a push plate 24, a pull plate 25, a first friction band 26, an electrically controlled multi-way valve 20, and a friction ring 16. The electrically controlled multi-way valve 20 is fixed to the bottom inner wall of the mounting box 1 and is connected to the first airbag 4 through an air guide pipe. The support frame 19 is fixed to the bottom outer wall of the mounting box 1, and the first cylinder 18 and the first tension spring 23 are respectively fixed to the top outer wall of the support frame 19. The bottom outer wall of the push plate 24 is fixed to the output end of the first cylinder 18 and the top outer wall of the first tension spring 23. A set of pull plates 25 is fixed to the top outer wall of the push plate 24. The two ends of the first friction band 26 are respectively fixed to the top outer wall of the pull plate 25. The friction ring 16 is fixed to the outer wall of the rotating shaft 15. The first friction band 26 is sleeved on the outer wall of the friction ring 16. The input end of the first cylinder 18 is connected to the electric multi-way valve 20 through the air guide pipe. The electric multi-way valve 20 is electrically connected to the control panel. When the user depresses the simulated clutch pedal 3, the gas inside the first airbag 4 is injected into the first cylinder 18 through the electronically controlled multi-way valve 20 and the air guide pipe. The output end of the first cylinder 18 pushes the push plate 24 to move upward to the corresponding height, causing the first friction band 26 to move upward and away from the friction ring 16. This releases the first friction band 26 from the friction ring 16, allowing the simulated gear lever 10 to be pushed left and right under the support and guidance of the rotating shaft 15. When the user releases the simulated clutch pedal 3, the push plate 24 will move downward rapidly under the elastic force of the first tension spring 23, thereby causing the first friction band 26 to move downward and re-fit onto the outer wall of the friction ring 16. At the same time, the gas inside the first cylinder 18 is refilled into the first airbag 4. The friction between the friction ring 16 and the first friction band 26 limits the rotating shaft 15, preventing the rotating shaft 15 from rotating easily when the simulated clutch pedal 3 is not depressed. The front and rear gear adjustment clutch simulation mechanism includes a mounting slot 40, a second cylinder 42, a three-way valve 21, a movable frame 39, a second tension spring 45, and a second friction band 36. The mounting slot 40 is opened on the outer wall of the rotating frame 22. The second cylinder 42 is fixed on the inner wall of the mounting slot 40. The input end of the second cylinder 42 is connected to the three-way valve 21. The three-way valve 21 is connected to the electronically controlled multi-way valve 20 through an air guide pipe. The movable frame 39 is fixed on the output end of the second cylinder 42. The second friction band 36 is fixed on the top outer wall of the movable frame 39 and is sleeved on the outer wall of the rotating rod 34. The second tension spring 45 is fixed on the bottom outer wall of the movable frame 39 and its bottom end is fixed on the outer wall of the rotating frame 22. When the user presses the simulated clutch pedal 3, the gas inside the first airbag 4 is injected into the second cylinder 42 through the three-way valve 21 and the air guide pipe. The second cylinder 42 pushes the movable frame 39 upward a corresponding distance, so that the second friction band 36 moves away from the outer wall of the rotating rod 34, releasing the friction between the second friction band 36 and the rotating rod 34, allowing the rotating rod 34 to rotate under the forward and backward push of the simulated gear lever 10. After the user releases the simulated clutch pedal 3, the movable frame 39 moves downward and resets under the elastic force of the second tension spring 45, so that the second friction band 36 is once again fitted onto the outer wall of the rotating rod 34, and at the same time, the gas inside the second cylinder 42 is re-injected into the first airbag 4. The friction between the second friction band 36 and the rotating rod 34 restricts the forward and backward rotation of the rotating rod 34.

[0027] In this embodiment, the air ducts all adopt air ducts with a large inner diameter, so that the gas can be quickly filled and released inside the first airbag 4, and the clutch simulation pedal 3 can be raised and lowered relatively quickly under the support of the first airbag 4, thereby improving the realism of the clutch pedal simulation.

[0028] The automatic gear shifting mechanism includes a push plate 8, a connecting rod 7, a control button 9, a movable column 43, a second airbag 12, a first cross-shaped guide groove 41, an inclined groove 46, and a second cross-shaped guide groove 44. The control button 9 is located on the top outer wall of the top cover 13 and is electrically connected to the control panel. The second cross-shaped guide groove 44 and the first cross-shaped guide groove 41 are respectively opened on both sides of the middle channel of the gear adjustment guide groove 11. The movable column 43 is slidably connected to the inner walls of the second cross-shaped guide groove 44 and the first cross-shaped guide groove 41. The second airbag 12 is located on the inner wall of the first cross-shaped guide groove 41 and is connected to the three-way valve 21 through an air guide pipe. The connecting rod 7 is fixed on the top outer wall of the movable column 43. The push plate 8 is fixed on the outer wall of the connecting rod 7. The control button 9 is electrically connected to the control panel. The inclined groove 46 is opened on one side of the push plate 8 opposite to the control button 9, and the height of the inclined groove 46 is greater than or equal to the height of the control button 9. When automatic transmission simulation is required, the user pushes the pusher 8 forward. When the inclined groove 46 on one side of the pusher 8 moves to the side of the control button 9, the control button 9 can be pressed down through the inclined groove 46. After the pusher 8 passes the control button 9, the control button 9 will pop up again. At this time, the pusher 8 can be stopped. The popped-up control button 9 can block the other side of the pusher 8 to limit the pusher 8. When the control button 9 is pressed, the control panel will control the electronic multi-way valve 20 to close. At this time, the user will not be able to press down the clutch simulation pedal 3, indicating that the gear simulation has entered the automatic transmission simulation mode. When the moving column 43 moves forward under the push of the push plate 8, one end will insert into the first cross-shaped guide groove 41. While blocking the openings on both sides of the middle part of the gear adjustment guide groove 11, it will squeeze the second airbag 12 inside the first cross-shaped guide groove 41, allowing the gas inside the second airbag 12 to fill the second cylinder 42, thereby releasing the friction limit of the second friction band 36 on the rotating rod 34. At this time, the user can push the simulated gear lever 10 located in the middle part of the gear adjustment guide groove 11 to rotate back and forth, driving the conductive connector 38 to switch between the three conductive plates 14 in the middle part, simulating the three gears of the automatic transmission. After the simulation ends, the user only needs to press the control button 9. At this time, the movable frame 39 will move downward and reset under the action of the second tension spring 45, thereby refilling the gas inside the second cylinder 42 into the second air bag 12. At this time, the second air bag 12 will move back against the movable column 43, so that the push plate 8 will automatically pass over the top of the pressed control button 9. Then the user pushes the push plate 8 and the movable column 43 back to reset, thereby releasing the obstruction of the movable column 43 on the gear adjustment guide groove 11. At the same time, when the control button 9 is pressed, the control panel will re-control the opening of the electronically controlled multi-way valve 20, thereby switching back to the manual gear simulation mode, allowing the gear simulation device to quickly switch between manual and automatic gear simulation modes.

[0029] In this embodiment, the vehicle driving simulator can be an intelligent device such as a smart computer or a gaming device that can run vehicle driving simulation software. It receives control signals sent by the control panel and controls the vehicle driving simulation software to perform driving simulation at the vehicle speed of the corresponding gear. Both the driving simulator and the corresponding intelligent device are currently available on the market and are mature technologies. The specific working principle will not be elaborated here.

[0030] In this embodiment, when the user does not press the clutch simulation pedal 3, the left and right gear adjustment clutch simulation mechanism and the front and rear gear adjustment clutch simulation mechanism can respectively limit the rotating shaft 15 rotatably connected to the inner wall of the mounting box 1 and the rotating rod 34 rotatably connected to the inner wall of the rotating frame 22, so that the user cannot adjust the gear by pushing the simulated gear lever 10 in the front, back, left and right when the user does not press the clutch simulation pedal 3. When the user presses the clutch simulation pedal 3, the clutch simulation pedal 3 will pressurize the first airbag 4, and the gas inside the first airbag 4 will fill the left and right gear adjustment clutch simulation mechanism and the front and rear gear adjustment clutch simulation mechanism. This will drive these two mechanisms to release the restriction on the rotating shaft 15 and the rotating rod 34, so that the user can push the simulated gear lever 10 to switch gears in all directions after pressing the clutch simulation pedal 3, simulating the gear shifting operation environment of a manual transmission. When practicing automatic gear shifting, first push the simulated gear lever 10 to the center of the gear shifting guide groove 11, then push the automatic gear shifting mechanism forward. The automatic gear shifting mechanism will limit the simulated gear lever 10 to the middle of the gear shifting guide groove 11, allowing the simulated gear lever 10 to only move back and forth under the guidance of the middle of the gear shifting guide groove 11. When pushing the automatic gear shifting mechanism forward, the front and rear gear shifting clutch simulation mechanism will also be pushed to release the restriction on the rotating lever 34, allowing the user to push the simulated gear lever 10 to rotate back and forth, simulating the D, N, and R gears of the automatic transmission. This allows the gear shifting simulation device to quickly switch between automatic and manual transmission simulation.

[0031] When the user pushes the simulated gear lever 10 to rotate back and forth under the guidance of the rotating rod 34, the rotating rod 34 will drive the telescopic rod 32 on one side to rotate together with the rotating rod 34 through the universal coupling 33, which will drive the gear 35 to push the second toothed plate 31 meshing with it to move back and forth a corresponding distance under the guidance of the guide frame 30, so that the conductive connector 38 on the outer wall of the elastic metal sheet 37 can move to the corresponding conductive sheet 14 that marks the corresponding gear position according to the angle of the rotation of the rotating rod 34. When the user pushes the simulated gear lever 10 to rotate left and right under the guidance of the rotating shaft 15, the gear plate 27 on the outer wall of the rotating shaft 15 will push the first gear plate 28, which meshes with it, to move up and down a corresponding distance under the guidance of the guide rail 17. This allows the second gear plate 31 to move up and down a corresponding distance along with the L-shaped connecting plate 29, so that the conductive connector 38 can follow the left and right swaying of the simulated gear lever 10 and switch to the side of the conductive plate 14 corresponding to the first / second, third / fourth, and fifth / reverse gears of the manual gear. Then, by pushing the simulated gear lever 10 back and forth, the conductive connector 38 can be moved to the conductive plate 14 that marks the corresponding manual gear. After the conductive connector 38 is connected to the conductive plate 14 that marks the corresponding gear, the control panel receives the corresponding electrical signal and controls the vehicle driving simulator to simulate the vehicle speed in the corresponding gear, thus accurately simulating the manual gear adjustment.

[0032] When the user shifts gears and releases the simulated clutch pedal 3, the left / right gear shifting clutch simulation mechanism and the front / rear gear shifting clutch simulation mechanism will re-limit the rotating shaft 15 and the rotating lever 34. Example 2: A vehicle driving simulator gear shifting device, such as Figure 1 As shown, this embodiment makes the following improvements based on embodiment 1: The outer wall of the mounting plate 2 is provided with a brake simulation pedal 5 and an accelerator simulation pedal 6, which are electrically connected to the control panel respectively; the user can send corresponding control signals to the control panel by pressing the accelerator simulation pedal 6 and the brake simulation pedal 5, and the control panel controls the vehicle driving simulator to simulate the corresponding vehicle acceleration and braking situations. With the simulation of manual and automatic gears, the user can experience a more realistic vehicle driving simulation effect.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
