The pedal is fixed at one end of the connecting rod, and the other end of the connecting rod is provided with a fixed block, which is welded to the end of the connecting rod as a whole and movably connected to the bracket; the diaphragm spring clutch is fixedly connected to the bracket through its pressure plate, and the spring fixing seat is welded to the center position of the diaphragm spring of the clutch; one end of the push rod is welded to the center position of the spring fixing seat, and the other end is movably connected to the fixed block; the spring positioning seat is arranged on the push rod, and the free travel spring is arranged on the push rod between the spring fixing seat and the spring positioning seat; one end of the movable connecting rod is movably connected to the bracket, and the other end is movably connected to the fixed block, and the connecting line of the two end points is inclined to the right. This patent is simple to process and improves the realism of the car driving simulator.

[0004] In the above patent, a spring positioning seat is arranged on the top rod, and a free travel spring is arranged on the top rod between the spring fixing seat and the spring positioning seat; one end of the movable connecting rod is movably connected to the bracket, thereby improving the realism of the car driving simulator, but it is difficult to prevent the high-frequency impact loss caused by excessive pedaling. The high-frequency impact caused by excessive pedaling far exceeds the design tolerance range of the pedal, which causes sudden failure of the pedal during use, causing problems such as pedal jamming or failure. Therefore, it is very necessary to design a pedal transmission structure of a car driving simulator that is highly practical and can prevent high-frequency impact loss caused by excessive pedaling.

When the foot pedal moves downward, the simulation spring is pulled. The simulation spring deforms and stores energy under the pull of the foot pedal. After the driver releases the foot pedal, the foot pedal can be driven to reset by the simulation spring. The simulation hole is formed at the top of the mounting plate. The gas inside the simulation frame slowly discharges through the collision prevention hole, causing the simulation rod to slowly move downward. The slow downward movement of the simulation rod drives the collision prevention plate to move downward.

[0007] According to the above technical solutions, a sealing ring is provided between the simulation frame and the simulation rod. The sealing performance between the simulation frame and the simulation rod can be increased through the sealing ring. The free end material of the elastic telescopic rod is polyurethane rubber. The wear resistance of the free end of the elastic telescopic rod can be increased by the fact that the free end material of the elastic telescopic rod is polyurethane rubber. The left side of the elastic telescopic rod is provided with an inclined surface.

[0008] According to the above technical solutions, the collision prevention plate is in contact with the elastic telescopic rod. A first spring is provided between the simulation frame and the simulation rod. When the simulation rod moves downward, the first spring is compressed. The first spring deforms and stores energy under the extrusion of the simulation rod. After the driver releases the foot pedal, the simulation rod can be driven to return to the initial position by the first spring. The simulation rod is in contact with the simulation hole. The delayed reset of the simulation rod and the mounting plate drives the delayed reset of the foot pedal.

[0009] According to the above technical solution, it further includes a fastening component and an adjusting component. The fastening component is used to eliminate the loosening or shaking of the connecting wire when stepping on the foot pedal, and the adjusting component is used to simulate the required foot pedal stepping force of different vehicle models.

After the fixing frame disengages from the contact with the mounting plate, the fixing spring can drive the fixing frame to reset. The clamping plate is fixedly installed on the right side of the fixing frame, and the clamping frame is fixedly installed on the bottom of the inner wall of the simulation groove.

[0010] According to the above technical solution, the fastening component further includes an elastic telescopic block and a movable hole. The elastic telescopic block fixedly penetrates the left and right walls of the clamping plate. The movable end of the elastic telescopic block retracts under the reaction force of the extruded connecting wire, and a liquid is arranged inside the elastic telescopic block.

[0011] According to the above technical solution, a rubber ring is arranged between the fixed end and the movable end of the elastic telescopic block. The rubber ring can increase the sealing performance between the free end and the movable end of the elastic telescopic block. The right side of the movable end of the elastic telescopic block is set as an arc surface, and the left side of the fixing frame is set as an arc surface. When the elastic telescopic block moves to the right, the movable end of the elastic telescopic block contacts the connecting wire and extrudes the connecting wire.

[0012] According to the above technical solution, the adjusting component includes an adjusting hole, a square hole, an adjusting plate, a U-shaped plate and an adjusting spring. Pushing the adjusting plate up and down can simulate the required foot pedal stepping force of different vehicle models. The adjusting hole is opened on the right side of the foot pedal, the square hole is opened on the right side of the foot pedal, the adjusting plate is slidably installed on the inner wall of the adjusting hole, the U-shaped plate slidably penetrates the left and right walls of the adjusting plate, the adjusting spring is arranged between the adjusting plate and the U-shaped plate. When the U-shaped plate moves to the right, it pulls the adjusting spring, and the adjusting spring deforms and stores energy under the pull of the U-shaped plate. After releasing the U-shaped plate, the adjusting spring can drive the U-shaped plate to reset.

[0013] According to the above technical solution, the adjusting component further includes an elastic telescopic rod, an arc-shaped plate and a rubber tube. The elastic telescopic rod is fixedly installed on the left side of the foot pedal, the arc-shaped plate is fixedly installed on the front side of the U-shaped plate, and the rubber tube is arranged between the elastic telescopic block and the elastic telescopic rod. The free end of the elastic telescopic rod moves backward under the extrusion of the liquid entering the elastic telescopic rod.

[0014] According to the above technical solution, a rubber ring is provided between the fixed end and the free end of the elastic telescopic rod. The rubber ring can increase the sealing performance between the fixed end and the free end of the elastic telescopic rod. There is liquid inside the elastic telescopic rod. The rubber tube contacts the inner wall of the simulation hole. The arc-shaped plate is limited by the free end of the elastic telescopic rod, causing the U-shaped plate to be unable to slide left and right.

[0015] The usage method of the foot pedal transmission structure of the car driving simulator. Using the foot pedal transmission structure of the above-mentioned car driving simulator, it includes the following steps: Step 1: Adjust the front-back and height positions of the seat according to the height to ensure that the legs stretch naturally, the knees are slightly bent, and the pedal can be easily stepped on the bottom when stepping on it. Step 2: The driver steps on the foot pedal. The foot pedal moves downward under the stepping of the driver, and the downward movement of the foot pedal drives the mounting plate to move downward. Step 3: The downward movement of the mounting plate drives the simulation rod to move downward. The downward movement of the simulation rod squeezes the gas inside the simulation frame. Step 4: The gas inside the simulation frame is slowly discharged through the anti-collision hole under the extrusion of the simulation rod. The slow discharge of the gas inside the simulation frame through the anti-collision hole causes the simulation rod to move downward at a slow speed. Step 5: After the driver releases the rear foot pedal, check whether the foot pedal returns completely to prevent misjudgment of signals by the simulator.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) In this invention, the slow downward movement of the simulation rod drives the anti-collision plate to move downward. The anti-collision plate moves downward and contacts the inclined surface of the movable end of the elastic telescopic rod and squeezes the movable end of the elastic telescopic rod. The buffer structure absorbs high-frequency impact energy, which can avoid deformation of metal parts due to stress concentration, thereby extending the service life of the foot pedal transmission structure and ensuring the safety of the operator during use. The delayed reset of the simulation rod and the mounting plate drives the delayed reset of the foot pedal. The delayed reset of the foot pedal can simulate the slow return of the clutch pedal of old vehicles and train the trainees' ability to handle starting stalls or shifting jerks.

[0017] (2) In this invention, the movement of the fixed frame to the right drives the clamping plate to move. The clamping plate moves and contacts the clamping frame and clamps the connection line of the simulation plate. The connection line bends repeatedly with the movement of the foot pedal and is prone to metal fatigue at the joint. The clamping plate fixes the bending radius of the connection line, thereby preventing the connection line from being pinched or worn.

[0018] (3) In the present invention, the elastic telescopic block is moved to the right side so that the movable end of the elastic telescopic block contacts the connecting wire and squeezes the connecting wire. The further fixation of the elastic telescopic block can prevent the cable from falling off due to the shaking of the connecting wire. The fixing frame is moved to the left side to reset, which drives the clamping plate to move and reset, thereby loosening the connecting wire and facilitating the maintenance of the connecting wire.

[0019] (4) The invention prevents the U-shaped plate from sliding left and right, thereby ensuring that the U-shaped plate will not loosen due to excessive impact force. The fixed design of the U-shaped plate can ensure the consistency of pedal feedback, thereby avoiding incorrect adjustment of the pedal force due to displacement of the U-shaped plate.

[0020] (5) This invention can simulate the pedal force required for different vehicle models by pushing the adjustment plate up and down. By switching the pedal force feedback in real time through the adjustment plate, it can avoid the solidification of operating habits caused by fixed force simulation, thereby reducing the risk of misoperation when actually driving across vehicle models.

The simulation hole 12 is opened on the top of the mounting plate 6. By buffering and absorbing high-frequency impact energy, it is possible to prevent metal components from deforming due to stress concentration, thereby extending the service life of the foot pedal transmission structure and ensuring the safety of the operator during use.

[0025] A sealing ring is arranged between the simulation frame 4 and the simulation rod 5. By means of the sealing ring, the sealing performance between the simulation frame 4 and the simulation rod 5 can be increased. The free end material of the elastic telescopic rod 9 is polyurethane rubber. By setting the free end material of the elastic telescopic rod 9 as polyurethane rubber, the wear resistance of the free end of the elastic telescopic rod 9 can be increased. The left side of the elastic telescopic rod 9 is set as an inclined surface.

[0026] The anti-collision plate 8 contacts the elastic telescopic rod 9. A first spring is arranged between the simulation frame 4 and the simulation rod 5. When the simulation rod 5 moves downward, it squeezes the first spring. The first spring deforms and stores energy under the extrusion of the simulation rod 5. After the driver releases the foot pedal 7, the first spring can drive the simulation rod 5 to return to its initial position. The simulation rod 5 contacts the simulation hole 12. The delayed reset of the simulation rod 5 and the mounting plate 6 drives the foot pedal 7 to reset with a delay.

[0027] Usage method of the foot pedal transmission structure of an automotive driving simulator. Using the foot pedal transmission structure of the above-mentioned automotive driving simulator, it includes the following steps: Step 1: Adjust the front-back and height positions of the seat according to the height to ensure that the legs stretch naturally and the knees are slightly bent when stepping on the pedal, and the pedal can be easily stepped to the bottom. Step 2: The driver steps on the foot pedal 7. The foot pedal 7 moves downward under the driver's stepping, and the downward movement of the foot pedal 7 drives the mounting plate 6 to move downward. Step 3: The downward movement of the mounting plate 6 drives the simulation rod 5 to move downward, and the downward movement of the simulation rod 5 squeezes the gas inside the simulation frame 4. Step 4: The gas inside the simulation frame 4 is slowly discharged through the anti-collision hole 10 under the extrusion of the simulation rod 5. The slow discharge of the gas inside the simulation frame 4 through the anti-collision hole 10 causes the simulation rod 5 to move downward at a slow speed. Step 5: After the driver releases the rear foot pedal 7, check whether the foot pedal 7 is fully reset to prevent misjudgment of signals by the simulator.

[0028] During operation, the driver steps on the foot pedal 7. The foot pedal 7 moves downward under the driver's stepping force. The downward movement of the foot pedal 7 drives the mounting plate 6 to move downward. The downward movement of the mounting plate 6 drives the simulation rod 5 to move downward. The downward movement of the simulation rod 5 squeezes the gas inside the simulation box 4. The gas inside the simulation box 4 is slowly discharged through the anti-collision holes 10 under the extrusion of the simulation rod 5. The slow discharge of the gas inside the simulation box 4 through the anti-collision holes 10 causes the simulation rod 5 to move downward at a slow speed. The slow downward movement of the simulation rod 5 drives the anti-collision plate 8 to move downward. The downward movement of the anti-collision plate 8 contacts the inclined surface of the movable end of the elastic telescopic rod 9 and squeezes the movable end of the elastic telescopic rod 9. The movable end of the elastic telescopic rod 9 moves upward and retracts under the extrusion of the anti-collision plate 8. After the driver releases the foot pedal 7, the simulation rod 5 moves upward and resets under the elastic force of the first spring. The upward movement and reset of the simulation rod 5 drive the anti-collision plate 8 to move. The upward movement of the anti-collision plate 8 contacts the bottom of the movable end of the elastic telescopic rod 9 and squeezes the movable end of the elastic telescopic rod 9. The movable end of the elastic telescopic rod 9 deforms under the extrusion of the anti-collision plate 8. The deformation of the movable end of the elastic telescopic rod 9 delays the reset speed of the simulation rod 5 and the mounting plate 6. The delayed reset of the simulation rod 5 and the mounting plate 6 drives the foot pedal 7 to reset with a delay. Embodiment Two:

[0029] Please refer to Figures 1-7 , on the basis of Embodiment One, in this embodiment, it further includes a fastening component and an adjusting component. The fastening component is used to eliminate the looseness or shaking of the connecting wire when stepping on the foot pedal 7, and the adjusting component is used to simulate the required stepping force of the foot pedal 7 for different vehicle models. The fastening component includes a fixing rod 131, a fixing frame 132, a fixing spring 133, a clamping plate 134, and a clamping frame 135. The fixing rod 131 is fixedly installed on the inner wall of the simulation groove 2. The fixing frame 132 is slidably installed on the circumferential surface of the fixing rod 131. The fixing spring 133 is arranged between the fixing frame 132 and the simulation groove 2. A connecting wire is arranged inside the simulation groove 2 for transmitting simulation signals to the simulator. When the fixing frame 132 moves to the right, it pulls the fixing spring 133. The fixing spring 133 deforms and stores energy under the pulling of the fixing frame 132. After the fixing frame 132 is separated from the contact with the mounting plate 6, the fixing spring 133 can drive the fixing frame 132 to reset. The clamping plate 134 is fixedly installed on the right side of the fixing frame 132. The clamping frame 135 is fixedly installed on the bottom of the inner wall of the simulation groove 2. The connecting wire bends repeatedly as the foot pedal 7 moves, and metal fatigue is likely to occur at the joint. The clamping plate 134 fixes the bending radius of the connecting wire, thereby preventing the connecting wire from being pinched or worn.

[0030] The fastening component further includes an elastic telescopic block 136 and a movable hole 137. The elastic telescopic block 136 fixedly penetrates the left and right walls of the clamping plate 134. The movable end of the elastic telescopic block 136 retracts under the reaction force of the squeezed connecting wire. There is liquid inside the elastic telescopic block 136.

[0031] A rubber ring is arranged between the fixed end of the elastic telescopic block 136 and the movable end of the elastic telescopic block 136, and the rubber ring can increase the sealing between the fixed end of the elastic telescopic block 136 and the fixed end of the elastic telescopic block 136. The right side of the movable end of the elastic telescopic block 136 is arranged as an arc surface, and the left side of the fixed frame 132 is arranged as an arc surface. The elastic telescopic block 136 moves to the right so that the movable end of the elastic telescopic block 136 contacts and squeezes the connecting line. The further fixation of the elastic telescopic block 136 can prevent the cable from falling off due to the shaking of the connecting line, and the fixing frame 132 moves to the left to reset, driving the clamping plate 134 to move and reset to loosen the connecting line, thereby facilitating the inspection of the connecting line.

[0032] The adjustment component includes an adjustment hole 141, a square hole 142, an adjustment plate 143, a U-shaped plate 144 and an adjustment spring 145. The adjustment hole 141 is opened on the right side of the foot pedal 7, the square hole 142 is opened on the right side of the foot pedal 7, the adjustment plate 143 is slidably installed on the inner wall of the adjustment hole 141, the U-shaped plate 144 slides through the left and right walls of the adjustment plate 143, and the adjustment spring 145 is arranged between the adjustment plate 143 and the U-shaped plate 144. The U-shaped plate 144 moves to the right to pull the adjustment spring 145. The adjustment spring 145 is deformed and accumulates force due to the pulling of the U-shaped plate 144. After the U-shaped plate 144 is released, the U-shaped plate 144 can be driven to reset by the adjustment spring 145. The real-time switching of the pedal 7 force feedback by the adjustment plate 143 can avoid the solidification of operating habits caused by fixed force simulation, thereby reducing the risk of misoperation during actual driving of cross-model vehicles.

[0033] The adjustment component also includes an elastic telescopic rod 146, an arc plate 147 and a rubber tube 148. The elastic telescopic rod 146 is fixedly installed on the left side of the foot pedal 7, the arc plate 147 is fixedly installed on the front side of the U-shaped plate 144, and the rubber tube 148 is arranged between the elastic telescopic block 136 and the elastic telescopic rod 146. The free end of the elastic telescopic rod 146 is squeezed by the liquid entering the elastic telescopic rod 146 and moves toward the rear side.

[0034] A rubber ring is arranged between the fixed end of the elastic telescopic rod 146 and the free end of the elastic telescopic rod 146, and the rubber ring can increase the sealing between the fixed end of the elastic telescopic rod 146 and the free end of the elastic telescopic rod 146. Liquid is arranged inside the elastic telescopic rod 146, and the rubber tube 148 is in contact with the inner wall of the simulation hole 12. The arc plate 147 is limited by the free end of the elastic telescopic rod 146, so that the U-shaped plate 144 cannot slide left and right. The fixed design of the U-shaped plate 144 can ensure the consistency of the feedback of the foot pedal 7, thereby avoiding the misadjustment of the pedaling force of the foot pedal 7 due to the displacement of the U-shaped plate 144.

[0035] During operation, the mounting plate 6 moves downward and contacts the curved surface of the fixing frame 132 and squeezes the fixing frame 132. The fixing frame 132 moves to the right side due to the squeezing of the mounting plate 6. The fixing frame 132 moves to the right side to drive the clamping plate 134 to move. The clamping plate 134 moves to contact the clamping frame 135 and clamps the connecting wire of the simulation board 1. At the same time, the clamping plate 134 moves to the right side to drive the elastic telescopic block 136 to move to the right side. The elastic telescopic block 136 moves to the right side so that the movable end of the elastic telescopic block 136 contacts the connecting wire and clamps the connecting wire of the simulation board 1. The connecting line is squeezed, and at the same time, the movable end of the elastic telescopic block 136 retracts due to the reaction force of the squeezed connecting line. After the driver releases the foot pedal 7, the simulation rod 5 moves upward and resets under the elastic force of spring 1, driving the mounting plate 6 to move. The mounting plate 6 moves out of contact with the fixed frame 132. After the fixed frame 132 is separated from the contact with the mounting plate 6, the fixed frame 132 moves to the left and resets under the elastic force of the fixing spring 133. The fixed frame 132 moves to the left and resets, driving the clamping plate 134 to move and reset to release the connecting line.

[0036] When the movable end of the elastic telescopic block 136 contracts inwardly, the volume of its internal cavity decreases, which produces a squeezing effect on the filled liquid. The pressurized liquid flows into the elastic telescopic rod 146 through the channel of the rubber tube 148. The liquid entering the elastic telescopic rod 146 squeezes the free end of the elastic telescopic rod 146. The free end of the elastic telescopic rod 146 is squeezed by the liquid entering the elastic telescopic rod 146 and moves backward. The free end of the elastic telescopic rod 146 moves backward and contacts the arc plate 147 and limits the arc plate 147. The arc plate 147 is limited by the free end of the elastic telescopic rod 146, causing the U-shaped plate 14 4 cannot slide left and right, the U-shaped plate 144 cannot slide left and right, thereby ensuring that the U-shaped plate 144 will not loosen due to excessive impact force. After the driver releases the foot pedal 7, the arc plate 147 will be separated from the contact with the free end of the elastic telescopic rod 146. After the free end of the elastic telescopic rod 146 is separated from the contact with the arc plate 147, the U-shaped plate 144 is manually pulled to move to the right. The U-shaped plate 144 moves to the right to be separated from the contact with the square hole 142 and releases the limit on the adjustment plate 143. After the limit of the adjustment plate 143 is released, the adjustment plate 143 is pushed up and down to simulate the required pedal 7 stepping force of different vehicle models.
