Description

Technical Field

[0001] The present invention relates to the technical field of driving simulators, and in particular to a simulated driving device for training vehicle drivers. Background Art

[0002] "Simulated driving" is also known as automobile driving simulation or virtual automobile driving. Simulated driving enables the experiencer to experience an automobile driving experience with visual, auditory, and somatic sensations close to the real effect in a virtual driving environment. Simulated driving has the advantages of realistic effect, energy saving, safety, economy, being unrestricted by time, climate, and site, high driving training efficiency, and short training cycle, and is widely used in the development of new vehicle models and driving training.

[0003] According to the driving mode, it is divided into two types: manual transmission and automatic transmission. The manual transmission requires higher coordination ability of hands and feet. The clutch plays the role of connecting and disconnecting the engine and the transmission, and mainly executes the cooperation with the gear lever to complete gear shifting. Since the trainees do not master driving skills proficiently enough, it is easy to release the clutch too quickly. In actual driving, this phenomenon will cause the vehicle to shake or even stall. However, virtual driving cannot simulate the real driving feeling, which is not conducive to cultivating the trainees' sense of vehicle. In addition, if the vehicle speed is not controlled well, the steering wheel will be turned too quickly during turning, which is not only easy to damage the steering wheel, but also cannot cultivate the trainees' correct driving. Therefore, it is necessary to propose a simulated driving device with strong authenticity. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a simulated driving device for training vehicle drivers, so as to solve the problems of poor protection of the steering wheel, inability to standardize the trainees' correct use of the steering wheel, and poor clutch perception ability proposed in the above background art.

[0005] To achieve the above purpose, the embodiments of the present invention provide the following technical solutions: A simulated driving device for training vehicle drivers includes a chassis, a center console, an electric seat, a display, and an electronic gear lever. The center console and the electric seat are respectively fixedly connected to the left and right ends of the upper surface of the chassis, and the center console is electrically connected to the electric seat. The display is installed on the top of the center console, and the display is electrically connected to the center console. The electronic gear lever is installed on the upper surface of the electric seat, and the electronic gear lever is electrically connected to the center console. A controller is arranged inside the center console. Under the control of the controller, the electronic gear lever is used for trainees to simulate gear shifting, and the electric seat is adjusted to a comfortable position for the trainees. A brake pedal and an accelerator pedal electrically connected to the center console are respectively installed on the left rear of the upper surface of the chassis, and braking and accelerating training are simulated through the brake pedal and the accelerator pedal. A steering mechanism is installed on the right side of the center console, a clutch mechanism is installed on the left front of the upper surface of the chassis, and a vibration motor electrically connected to the center console is installed on the front of the electric seat.

[0006] As a further solution of the present invention, the steering mechanism includes a box body installed on the right side of the center console. A rotatable steering wheel is installed at the center position of the box body, and the steering wheel is electrically connected to the center console. A first gear is installed at the bottom end of the steering wheel. A second gear meshing with the first gear is connected to the front side of the inner cavity of the box body through a pin shaft. A plurality of bumps are equidistantly installed on the upper surface of the second gear along the circumferential direction. An induction component is installed on the front side of the upper surface of the box body. The rotation speed of the steering wheel is sensed by the cooperation of the induction component and the bumps. A rotatable rotating shaft is installed at the rear side of the inner cavity of the box body. A buffer component and a third gear are respectively installed at the upper and lower ends of the outer wall of the rotating shaft, and the third gear is meshed with the first gear. Two left-right opposite baffles are installed on the rear side of the inner wall of the box body. The rotation of the steering wheel is buffered by the cooperation of the buffer component and the baffles; The rotation speed of the steering wheel is judged by the induction component. If it exceeds the turning speed of safe driving, the trainee can be reminded. The induction component rotates following the third gear, and the baffle restrains the movement of the induction component, playing a buffering role on the steering wheel and protecting the steering wheel.

[0007] As a further solution of the present invention, the transmission ratio of the first gear to the second gear is less than 1, and the transmission ratio of the first gear to the third gear is greater than 1.

[0008] As a further solution of the present invention, the rear side surface of the baffle is a curved surface.

[0009] As a further solution of the present invention, the induction component includes a limit cylinder installed on the front side of the upper surface of the box body. A travel switch electrically connected to the center console is installed at the top of the inner cavity of the limit cylinder. A lifting block capable of sliding up and down is inserted into the bottom of the inner cavity of the limit cylinder.

[0010] As a further solution of the present invention, both the bottom of the lifting block and the outer wall of the bump are triangular.

[0011] As a further solution of the present invention, the buffer component includes an outer rod installed at the top of the rotating shaft. A first spring and an inner rod are respectively inserted into the inner cavity of the outer rod from front to back. A roller is installed at the rear end of the inner rod. The roller is pushed by the elastic force of the first spring to contact the inner wall of the box body.

[0012] As a further solution of the present invention, the clutch mechanism includes a base installed at the left front of the upper surface of the chassis. A clutch pedal is connected to the right side of the base through a pin shaft, and the clutch pedal is electrically connected to the center console. One end of a connecting rod is connected to the top of the left side wall of the clutch pedal through a pin shaft. A clutch detection component is horizontally installed inside the base. The left end of the clutch detection component is connected to the other end of the connecting rod through a pin shaft.

[0013] As a further solution of the present invention, the clutch detection assembly includes a piston cylinder installed in the inner cavity of the base. A second spring and a first piston are inserted into the inner cavity of the piston cylinder from left to right. The first piston is pushed to move rightward under the elastic force of the second spring. One end of a piston rod is installed at the left end of the first piston, and the other end of the piston rod is connected to the bottom of the connecting rod through a pin shaft. Under the traction of the connecting rod, the clutch pedal can swing to the right. A pressure switch electrically connected to the center console is embedded at the right end of the bottom of the piston cylinder, and an air intake unit is installed at the center position of the right side wall of the piston cylinder; The air intake unit changes the air intake efficiency of the piston cylinder. The second spring pushes the first piston to move rightward, and the piston cylinder exhausts air. If the clutch pedal is released too quickly, the exhaust efficiency is constant, causing the air pressure in the piston cylinder to increase, thereby detecting the operation specification of the clutch pedal.

[0014] As a further solution of the present invention, the air intake unit includes a cylinder installed at the center position on the right side of the piston cylinder. A plurality of air intake holes are provided on the left side, upper and lower ends of the cylinder. A third spring and a second piston are inserted into the left and right sides of the inner cavity of the cylinder respectively. The second piston is pushed to move rightward under the elastic force of the third spring. A limit block is installed on the right side inner wall of the cylinder, and the limit block limits the moving distance of the second piston to prevent the second piston from popping out of the cylinder.

[0015] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: 1. In the present invention, by rotating the steering wheel, the first gear drives the second gear and the third gear to rotate. During the rotation of the second gear, the inclined surfaces of the convex block and the lifting block are mutually extruded. The rising height of the lifting block is proportional to the speed of the convex block. Once the lifting block triggers the travel switch, the display reminds the trainee that the steering wheel rotates too fast. The third gear rotates synchronously with the outer rod, allowing the roller to roll along the inner wall of the box. When the roller rolls onto the baffle, the curved surface of the baffle squeezes the inner rod. Since the included angle between the inner rod and the curved surface of the baffle is large, the baffle has a strong blocking effect on the third gear, buffering when the steering wheel rotates close to the limit. Therefore, it can not only standardize the actions of trainees in operating the steering wheel, cultivate good driving habits, but also protect the steering wheel and extend its service life; 2. In the present invention, through the swing of the clutch pedal, the connecting rod pulls the first piston to move leftward, and the piston cylinder inhales air through the air intake holes. When releasing the clutch pedal, the elastic force of the third spring presses on the first piston, controlling the gas release speed through the air intake holes. If the clutch pedal is released too quickly, the gas release cannot keep up with the movement of the first piston, and the air pressure in the piston cylinder increases. The pressure switch feeds back an electrical signal to the center console, causing the vibration motor to vibrate, simulating the real state of clutch use, making the clutch use more real, and being beneficial to cultivating the trainee's sense of vehicle.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0020] Embodiment, please refer to Figures 1-8, in the embodiment of the present invention, a simulated driving device for training vehicle drivers includes a chassis 1, a central control console 2, an electric seat 3, a display 4 and an electronic gear lever 5.

The electronic gear lever 5 is installed on the upper surface of the electric seat 3, and the electronic gear lever 5 is electrically connected to the central control console 2. A controller is provided inside the central control console 2. Under the control of the controller, the electronic gear lever 5 is used for trainees to simulate gear shifting, the electric seat 3 is adjusted to the comfortable position of the trainees. On the upper surface of the left rear of the chassis 1, a brake pedal 6 and an accelerator pedal 7 electrically connected to the central control console 2 are respectively installed. Braking and accelerating training are simulated through the brake pedal 6 and the accelerator pedal 7.

A second gear 84 meshing with the first gear 83 is connected by a pin shaft on the front side of the inner cavity of the box body 81. The transmission ratio of the first gear 83 to the second gear 84 is less than 1, which increases the angular velocity of the second gear 84 and increases the impact force of the convex block 85 on the lifting block 863. A plurality of convex blocks 85 are installed on the upper surface of the second gear 84 at equal intervals along the circumference. An induction component 86 is installed on the front side of the upper surface of the box body 81.

The transmission ratio of the first gear 83 to the third gear 89 is greater than 1, which reduces the angular velocity of the third gear 89. Two left-right opposite baffles 810 are installed on the rear side inner wall of the box body 81. The rear surface of the baffle 810 is a curved surface. The buffer component 88 is gradually squeezed by the curved surface of the baffle 810 to buffer the steering wheel 82.

A lifting block 863 that can slide up and down is inserted into the bottom of the inner cavity of the limit cylinder 861. The bottom of the lifting block 863 and the outer wall of the convex block 85 are both triangular. When the convex block 85 rotates, the inclined surface of the convex block 85 and the lifting block 863 cause the lifting block 863 to bounce upward.

[0023] Preferably, the buffer assembly 88 includes an outer rod 881 installed on the top of the rotating shaft 87. A first spring 882 and an inner rod 883 are inserted into the inner cavity of the outer rod 881 from front to back. A roller 884 is installed at the rear end of the inner rod 883. Under the elastic force of the first spring 882, the roller 884 is pushed into contact with the inner wall of the box body 81.

[0024] Preferably, the clutch mechanism 9 includes a base 91 installed at the front left of the upper surface of the chassis 1. The right side of the base 91 is connected by a pin shaft to a clutch pedal 92, and the clutch pedal 92 is electrically connected to the central control console 2. One end of a connecting rod 93 is connected to the top of the left side wall of the clutch pedal 92 by a pin shaft. A clutch detection assembly 94 is installed horizontally inside the base 91. The left end of the clutch detection assembly 94 is connected to the other end of the connecting rod 93 by a pin shaft.

[0025] Preferably, the clutch detection assembly 94 includes a piston cylinder 941 installed in the inner cavity of the base 91. A second spring 942 and a first piston 943 are inserted into the inner cavity of the piston cylinder 941 from left to right. Under the elastic force of the second spring 942, the first piston 943 is pushed to move rightward. One end of a piston rod 944 is installed at the left end of the first piston 943. The other end of the piston rod 944 is connected to the bottom of the connecting rod 93 by a pin shaft. Under the traction of the connecting rod 93, the clutch pedal 92 can swing to the right side. A pressure switch 945 electrically connected to the central control console 2 is embedded at the right end of the bottom of the piston cylinder 941. An air intake unit 946 is installed at the central position of the right side wall of the piston cylinder 941.

[0026] Preferably, the air intake unit 946 includes a cylinder 9461 installed at the central position of the right side of the piston cylinder 941. A plurality of air intake holes 9462 are formed on the left side, upper and lower ends of the cylinder 9461. A third spring 9463 and a second piston 9464 are inserted into the inner cavity of the cylinder 9461 from left to right. Under the elastic force of the third spring 9463, the second piston 9464 is pushed to move rightward. A limiting block 9465 is installed on the right side inner wall of the cylinder 9461. The limiting block 9465 limits the moving distance of the second piston 9464 to prevent the second piston 9464 from popping out of the cylinder 9461.

[0027] Working principle Step 1, the trainee conducts simulated driving according to the content on the display 4. By stepping on the clutch pedal 92, the engine is disconnected from the transmission. The electronic gear lever 5 is used to shift gears, the driving mode is switched, the brake pedal 6 and the accelerator pedal 7 are used to control the virtual vehicle to move forward, and the steering wheel 82 is rotated to change the driving direction. Step 2: When the trainee rotates the steering wheel 82 too fast and operates improperly, the first gear 83 drives the second gear 84 to rotate. Since the transmission ratio between the first gear 83 and the second gear 84 is less than 1, the rotation speed of the second gear 84 is increased. The inclined surface of the convex block 85 on the second gear 84 presses the inclined surface of the lifting block 863, prompting the lifting block 863 to move upward to trigger the travel switch 862. The travel switch 862 feeds an electrical signal back to the center console 2, and the display 4 reminds the trainee of improper operation to standardize the driving behavior of the trainee. Step 3: When turning, the first gear 83 drives the third gear 89 to rotate. When the steering wheel 82 is approaching the rotation limit, the roller 884 rolls onto the baffle 810. Due to the large deviation between the center line of the inner rod 883 and the inclined surface direction of the baffle 810, and the buffering of the rotation of the third gear 89 under the elastic force of the first spring 882, the impact force generated when the steering wheel 82 rotates is dissipated, protecting the steering wheel 82. Step 4: When shifting gears, the clutch pedal 92 drives the first piston 943 to move leftward through the connecting rod 93. The first piston 943 sucks air into the piston cylinder 941. When the suction force exceeds the elastic force of the third spring 9463, the second piston 9464 moves leftward, and the number of opened air intake holes 9462 increases, avoiding inhibiting the swing of the clutch pedal 92. After shifting gears, if the clutch pedal 92 is released too quickly, the elastic force of the second spring 942 pushes the first piston 943 to the right, and under the elastic force of the third spring 9463, the second piston 9464 is pushed to move rightward, the number of air outlet holes 9462 decreases, the air pressure in the piston cylinder 941 increases, the pressure switch 945 is triggered, feeds an electrical signal back to the center console 2, the vibration motor 10 starts to vibrate, and the electric seat 3 vibrates, simulating the jitter in an actual vehicle to make the simulated driving closer to actual driving.

[0028] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
