Description

Technical Field

[0001] This utility model relates to the field of racing simulator technology, and in particular to a pedal device and gaming equipment. Background Technology

[0002] The pedal mechanism is used to recreate and simulate the braking or accelerator experience during racing car driving. It uses sensors to collect data such as brake pedal displacement angle and pedal force to simulate the pedal action in racing. When the pedal mechanism is working, it needs to efficiently convert the motor's output torque into a force acting on the pedal to simulate the force feedback characteristics of a traditional mechanical pedal. Currently, common pedal mechanisms on the market achieve this conversion between motor torque and pedal force through the coordinated action of multiple sets of gears and linkages. This gear and linkage structure is cumbersome and complex, occupying a large space and resulting in a large overall size, limiting the adaptability of the pedal mechanism. Furthermore, the long force transmission path in the gear and linkage structure leads to friction loss and clearance errors, resulting in a response delay and insufficient accuracy in converting motor torque into pedal force, and low transmission efficiency between the motor and the pedal. Utility Model Content

[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing a pedal device that is simple in structure, easy to simplify spatial layout, occupies less space, has good adaptability, and has high transmission efficiency.

[0004] A pedal device includes a base plate, a motor fixedly connected to the base plate, a screw drive structure, a pedal, and a crank rotatable relative to the base plate. The screw drive structure includes a rotating component and a linear motion component rotatably engaged with the rotating component and movable in an axial direction parallel to the rotating component. The rotating component is connected to the output shaft of the motor. The crank includes a first end connected to the base plate and a second end connected to the linear motion component. The pedal is mounted on the side of the crank away from the first end. When the rotating component rotates following the output shaft of the motor, the linear motion component moves in an axial direction parallel to the rotating component to change the rotation angle of the crank.

[0005] The aforementioned pedal device combines a screw drive structure with a crank to convert the rotation of the motor output shaft into the linear motion of a linear motion component. This linear motion component then drives the crank to rotate, adjusting the pedal position. This converts the motor's output torque into a force acting on the pedal, simulating the force feedback of a traditional mechanical pedal. Through motor torque adjustment, dynamic control of the pedal force is achieved. Its simple structure simplifies the transmission chain and spatial layout between the motor torque and pedal force, reducing friction and clearance between components. The response speed of converting motor torque into pedal force is improved, resulting in rapid and precise force feedback. Its compact structure allows for adaptation to confined spaces, offering good spatial adaptability. Stable force transmission characteristics enhance the transmission efficiency between the motor and the pedal, improving system reliability.

[0006] In one embodiment, the rotating component is a lead screw, and the linear motion component includes a lead screw nut that rotates with the lead screw; or the rotating component includes a lead screw nut, and the linear motion component is a lead screw that rotates with the lead screw nut.

[0007] Thus, the output shaft of the motor can drive the lead screw to rotate, and then through the threaded engagement between the lead screw and the lead screw nut, the linear motion of the lead screw and nut can be achieved, thereby driving the crank to rotate. Alternatively, the output shaft of the motor can drive the lead screw and nut to rotate, and then through the threaded engagement between the lead screw and the lead screw nut, the linear motion of the lead screw can be achieved, thereby driving the crank to rotate. The two transmission methods can be interchanged to adapt to different production conditions.

[0008] In one embodiment, the rotating component includes a lead screw and nut, the linear motion component is a lead screw that rotates with the lead screw and nut, the rotating component also includes a transmission component connected to the lead screw and nut, and a coupling connecting the transmission component and the output shaft of the motor.

[0009] By setting up transmission components and couplings, the motor output shaft and rotating parts can be connected to achieve compatibility between the motor output shaft and rotating parts. The pedal height can be adjusted using commercially available rotating parts and motors without further modification to the structure of the motor output shaft and rotating parts to achieve direct connection between the two, thus reducing the cost of the pedal device.

[0010] In one embodiment, the rotating component is a lead screw nut, the linear motion component is a lead screw, the transmission component has a first mounting hole in the axial direction, and one end of the linear motion component is connected to the second end of the crank, while the other end is disposed in the first mounting hole.

[0011] By opening a first mounting hole on the transmission component and placing one end of the linear motion component inside the first mounting hole, the linear motion component is able to cooperate with the rotating component while limiting the linear motion path of the linear motion component. This achieves the guidance of the linear motion component by the first mounting hole, thereby reducing the sway of the linear motion component and improving the stability and reliability of the transmission.

[0012] In one embodiment, the transmission member is provided with a guide portion, and the linear motion component is provided with a mating portion. The guide portion and the mating portion cooperate to limit the motion trajectory of the linear motion component.

[0013] By cooperating with the guide part on the transmission component and the mating part on the linear motion component, the linear movement path of the linear motion component can be limited, and the linear movement stroke of the linear motion component can be limited.

[0014] In one embodiment, the pedal device further includes a cover assembly, the base plate includes a support portion, the cover assembly at least covers the lead screw drive structure, and the support portion is fixedly connected to the cover assembly;

[0015] The pedal device also includes a dust cover, which has a second mounting hole. The dust cover is fitted onto the linear motion component, and the linear motion component passes through the second mounting hole and is connected to the second end of the crank.

[0016] By setting up a housing assembly and a dust cover, the motor and lead screw drive structure can be encapsulated and protected, preventing dust and debris from entering the internal lead screw drive structure area. This avoids interference from dust and impurities with the operation of the lead screw drive structure and the motor, ensuring the reliability of the pedal device.

[0017] In one embodiment, the cover assembly has a through hole on the side near the pedal, the outer diameter of the dust cover is smaller than the inner diameter of the through hole, and the dust cover is at least partially disposed within the through hole.

[0018] In this way, while facilitating the fitting of the dust cover to the housing assembly, the dust cover can be inserted into the front end of the housing assembly to prevent dust from entering the internal screw drive structure area from the front end of the housing assembly, thereby achieving dust protection for the screw drive structure and the motor.

[0019] In one embodiment, the inner wall of the housing assembly is fitted with at least one bearing for supporting the transmission element.

[0020] By incorporating bearings, reliable support for the transmission components is achieved while reducing the shaking during rotation, thus ensuring the stability of both the transmission components and the pedal mechanism structure.

[0021] In one embodiment, the base plate has a limiting member at a first end adjacent to the crank for defining the crank angle.

[0022] By providing a limiting member on the side of the first end of the crank on the base plate, the maximum angle at which the crank approaches the motor can be limited, so that the crank rotates within a predetermined range.

[0023] This utility model also discloses a gaming device, which includes the aforementioned pedal device.

[0024] The aforementioned pedal device, when using the aforementioned pedal mechanism, converts the rotation of the motor output shaft into linear motion of a linear motion component through a screw drive structure combined with a crank. This linear motion component then drives the crank to rotate, adjusting the pedal position. This converts the motor's output torque into a force acting on the pedal, simulating the force feedback of a traditional mechanical pedal. Dynamic control of the pedal force is achieved through motor torque adjustment. Its simple structure simplifies the transmission chain and spatial layout between the motor torque and pedal force, reducing friction and clearance between components. The response speed of converting motor torque into pedal force is improved, resulting in rapid and precise force feedback. Its compact structure allows for adaptation to confined spaces, offering good spatial adaptability. Stable force transmission characteristics improve the transmission efficiency between the motor and the pedal, enhancing system reliability. Attached Figure Description

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] This utility model discloses a pedal device with a simple structure, convenient for simplifying spatial layout, small footprint, good adaptability, and high transmission efficiency. This pedal device is used in conjunction with a steering wheel device in driving simulation games or driving training software. In this design, the pedal device controls the vehicle's brakes and accelerator in the game, while the steering wheel device controls the vehicle's direction of travel in the game or driving training software. The racing game or driving training software is loaded on a client (such as a computer) to provide the user with a game or training interface. Thus, the three work together to simulate a realistic vehicle driving experience. In this embodiment, the pedal height is adjusted primarily by regulating the torque output of the motor, thereby providing resistance or assistance to the user when pressing the pedal, offering various different pedal usage experiences.

[0031] For specific details, please refer to... Figure 1-4 The pedal device 10 of this embodiment includes a base plate 100, a motor 200 fixedly connected to the base plate 100, a lead screw drive structure, a pedal 400, and a crank 300 rotatable relative to the base plate 100. The lead screw drive structure includes a rotating component 500 and a linear motion component 600 rotatably engaged with the rotating component 500 and movable in a direction parallel to the axial direction of the rotating component 500. The rotating component 500 is connected to the output shaft of the motor 200. In this embodiment, the rotating component 500 is drivenly connected to the output shaft of the motor 200 and rotates coaxially with the output shaft. The crank 300 includes a first end connected to the base plate 100 and a second end connected to the linear motion component 600. In this embodiment, the first end rotatably engages with the base plate 100, and the second end rotatably engages with the linear motion component 600. The pedal 400 is mounted on the side of the crank 300 away from the first end. In this embodiment, the pedal 400 is fixedly connected to the second end. As the rotating component 500 rotates following the output shaft of the motor, the linear motion component 600 moves in an axial direction parallel to the rotating component 500 to change the rotation angle of the crank 300. It is understood that, while meeting the user's pedaling needs, the pedal 400 can also be installed in other positions between the first and second ends, for example, between the mating part of the crank and the linear motion component and the first end, or between the mating part of the crank and the linear motion component and the second end, depending on the user's ease of use.

[0032] In an optional embodiment, the base plate 100, the motor 200, the connecting body composed of the lead screw transmission structure, and the crank 300 together form a triangular structure. Since the two ends of the crank 300 are respectively rotatably engaged with the base plate 100 and the linear motion component 600, when the second end of the crank 300 is subjected to the pressure of the pedal 400 or the thrust of the linear motion component 600, the crank 300 will rotate around the first end as the rotation center. In one case, through the rotational engagement of the linear motion component 600 and the rotating component 500, the linear motion component 600... Under the pressure of pedal 400, the pedal moves linearly, and the rotating component 500 drives the output shaft of motor 200 to rotate simultaneously, thereby obtaining the force of the user stepping on pedal 400 through the change of motor 200 parameters; in another case, the rotating component 500 rotates under the drive of motor output shaft 210, and the linear motion component 600 moves linearly along the axis of rotating component 500 and pushes or pulls the second end of crank 300 and pedal 400 to change the height of pedal 400, thereby improving the user's pedal 400 experience.

[0033] In an optional embodiment, the rotating component 500 and the linear motion component 600 achieve the conversion between rotational and linear motion through a threaded ball joint. Since the threaded ball joint structure consists of a lead screw, nut, balls, and a circulator (return mechanism), it utilizes the threaded raceways of the lead screw and nut to guide the rolling elements. The threaded raceways serve only as ball tracks, with the actual transmission completed by the rolling elements (balls). Essentially, it is a composite structure of a linear bearing and a helical track. The contact between the balls and the raceways is rolling friction, resulting in high transmission efficiency. Due to the circulator and the rolling engagement between the balls and the raceways, conditions are provided for the rotating component 500 to drive the linear motion component 600 in translation under the drive of the motor output shaft 210, and for the linear motion component 600 to translate under the pressure of the crank 300 and pedal 400, thereby driving the rotating component 500 and the motor output shaft 210 to rotate. In another embodiment, the rotating component 500 and the linear motion component 600 achieve the conversion between rotational and linear motion through a threaded trapezoidal lead screw and nut joint.

[0034] When the pedal device 10 is in use, if assistance is needed when the user applies force to the pedal 400, the motor 200 operates and drives the motor output shaft 210 and the rotating component 500 to rotate. This causes the linear motion component 600 to move linearly towards the motor 200, thus requiring less force from the user to achieve the desired pedal stroke and providing a pedaling experience with less resistance. If resistance is needed, the motor 200 drives the motor output shaft 210 to rotate in the opposite direction. The rotating component 500 rotates and causes the linear motion component 600 to move linearly away from the motor 200, lifting the pedal 400. The force exerted by the linear motion component 600 on the pedal 400 counteracts the force exerted by the user on the pedal 400, thus requiring more force from the user to achieve the desired pedal stroke and providing a pedaling experience with greater resistance. The magnitude of the aforementioned assistance or resistance can be adjusted according to the torque of the motor 200 as needed. By adjusting the torque of the motor 200, the resulting resistance or assistance will also change accordingly, so that the force feedback at the pedal 400 can change infinitely within a certain range (that is, the force feedback can be continuously and smoothly adjusted to any value within the design range, rather than switching to a fixed gear in a jump). The motor torque is linearly related to the pedal force, which makes it easy to accurately adjust the force feedback of the pedal 400 through the electronic control system, so that there are differences in the force feeling in different driving modes, providing users with different pedal 400 usage experiences.

[0035] In one embodiment, the pedal device 10 further includes a detection component 700, which includes an angle encoder 710 mounted on the base plate 100 for detecting the rotation angle of the crank 300, a motor encoder 720 mounted on the motor 200 facing away from the motor output shaft 210 for detecting motor parameters, a pressure sensor 730 mounted on the pedal 400 for detecting the force on the pedal, and a control circuit board 740 mounted on the base plate 100 and electrically connected to the angle encoder 710, the motor encoder 720, the pressure sensor 730, and the motor 200. The control circuit board 740 can be connected to an external client via a communication interface. In this way, the control circuit board 740 can transmit the received crank rotation angle change information, motor parameter information, and force information at the pedal to the client and display it on the game or training interface to show the corresponding data change information of the pedal device 10. The control circuit board 740 is also used to receive instructions from the client to control the operation of the motor 200 to adjust the operating parameters of the motor 200, such as motor speed and direction. Furthermore, a protective cover 110 is fixed to the upper surface of the base plate 100 below the motor 200. The control circuit board 740 is housed within the protective cover 110 and fixedly connected to the base plate 100 to achieve encapsulation and protection of the control circuit board 740. Of course, the outer surface of the protective cover 110 is provided with a communication interface 120 electrically connected to the control circuit board 740. This communication interface 120 provides a connection point between an external client and the control circuit board 740. A power module electrically connected to the control circuit board 740 is also provided inside the protective cover 110 to supply power to the pedal device 10.

[0036] In this embodiment, the first and second ends of the crank 300 are hinged to the linear motion component 600 and the base plate 100, respectively. When the user applies force to the pedal 400, the crank 300 rotates, and the linear motion component 600 is displaced towards the motor 200 under the push of the crank 300. At this time, the rotating component 500 rotates and drives the motor output shaft 210 to rotate synchronously (in the positive direction). During this process, the angle encoder 710, the motor encoder 720, and the pressure sensor 730 detect the corresponding data changes and transmit them to the control circuit board 740, which then transmits them to the external client to obtain the user's pedaling data. When user assistance is needed, the client sends an electrical signal to the control circuit board 740. The motor 200 operates under the action of the control circuit board 740, so that the motor output shaft 210 receives a force in the same direction (positive direction) as the rotation caused by the user's force, thereby reducing the force required by the user to reach the expected pedal stroke. Conversely, when resistance needs to be applied to the user, the client sends an electrical signal to the control circuit board 740. The motor 200 operates under the action of the control circuit board 740, so that the motor output shaft 210 receives a force in the opposite direction (reverse direction) to the rotation caused by the user's force, thereby increasing the force used by the user to reach the expected pedal travel.

[0037] The pedal device 10 also includes a cover assembly 800, which at least covers the lead screw drive structure. The cover assembly 800 includes a motor housing 810 covering the motor 200, a motor housing cover 820 located between the motor housing 810 and the crank 300 and detachably connected to the motor housing 810, and a front cover 830 fixedly connected to the motor housing cover 820 and covering the connection between the crank 300 and the linear motion component 600. The base plate includes a support portion 840, which is fixedly connected to the cover assembly 800. Preferably, the support portion 840 is fixedly connected to the motor housing 810. The motor housing 810, the motor housing cover 820, and the front cover 830 together form a housing to enclose the motor 200 and the lead screw drive structure, protecting the motor 200 and the lead screw drive structure, and also serving as a supporting frame for the installation of components inside the housing. In this embodiment, the motor housing cover 820 is snap-fitted to both the motor housing 810 and the front cover 830. In other embodiments, the motor housing cover 820 may also be threaded or screwed to the motor housing 810 and the front cover 830, or the motor housing cover 820 and the motor housing 810 may be integrally formed, or the motor housing cover 820 and the front cover 830 may be integrally formed. The support portion 840 includes two support plates that are disposed opposite to each other on both sides of the motor housing 810 and fixedly connected to the base plate 100. The support plates are screwed to the motor housing 810 to achieve a fixed connection between the motor housing 810 and the base plate 100, thereby supporting the motor 200 and components such as the lead screw drive structure. Preferably, the support plate and the base plate 100 are integrally formed. It should be noted that in this embodiment, the connection portion between the support plate and the motor housing 810 is close to the connection portion between the crank 300 and the linear motion component 600, so as to reduce the torque on the connection portion between the support plate and the motor housing 810 when the user steps on the pedal 400, thereby improving the stability of the entire pedal device 10 structure.

[0038] Furthermore, in this embodiment, a dust cover 610 and a connector 620 are provided at the end of the linear motion component 600 away from the motor 200. The dust cover 610 has a second mounting hole and is sleeved on the linear motion component 600. The linear motion component 600 passes through the second mounting hole and is connected to the second end of the crank 300. In this embodiment, the dust cover 610 is sleeved on the linear motion component 600 and covers the rotating component 500. One end of the connector 620 is fixedly connected to the dust cover 610 and the linear motion component 600, and the other end of the connector 620 is rotatably connected to the second end of the crank 300 (such as a hinge connection). The connector 620 is used to provide a connection between the linear motion component 600 and the crank 300. The dust cover 610 is housed within the front end cover 830 and seals the opening of the front end cover 830 to prevent dust and debris from entering the internal screw drive structure area from the opening of the front end cover 830. Furthermore, the housing assembly 800 has a through hole on the side near the pedal 400. The outer diameter of the dust cover 610 is smaller than the inner diameter of the through hole, and the dust cover 610 is at least partially disposed within the through hole. This facilitates the fitting of the dust cover 610 to the housing assembly 800, and allows the dust cover 610 to be inserted into the front end of the housing assembly 800 to prevent dust from entering the internal screw drive structure area from the front end of the housing assembly 800, thus achieving dust protection for the screw drive structure and the motor 200.

[0039] It should be noted that the lead screw drive structure in this solution includes two interchangeable forms. Specifically, the rotating component 500 is a lead screw, and the linear motion component 600 includes a lead screw nut that rotatably engages with the lead screw; or the rotating component 500 includes a lead screw nut, and the linear motion component 600 is a lead screw that rotatably engages with the lead screw nut. Thus, the lead screw can be rotated by the motor's output shaft, and the linear motion of the lead screw nut, through the threaded engagement between the lead screw and the lead screw nut, can be achieved to drive the crank. Alternatively, the lead screw nut can be rotated by the motor's output shaft, and the linear motion of the lead screw, through the threaded engagement between the lead screw and the lead screw nut, can be achieved to drive the crank. The two transmission methods are interchangeable to adapt to different production conditions.

[0040] In the case where the rotating component 500 includes a lead screw and nut, and the linear motion component 600 is a lead screw that rotatably engages with the lead screw and nut, the rotating component 500 also includes a transmission component 910 connected to the lead screw and nut, and a coupling 920 connecting the transmission component 910 and the output shaft of the motor. The transmission component 910 and the coupling 920 together form a connecting assembly 900. The transmission component 910 and the coupling 920 are used to connect the motor output shaft 210 and the rotating component 500 to achieve adaptation between the motor output shaft 210 and the rotating component 500. The pedal height can be adjusted using commercially available rotating components and motors without further modification to the structure of the motor output shaft and the rotating component to achieve direct connection, thus reducing the cost of the pedal device. Furthermore, at least one bearing for supporting the transmission component 910 is installed on the inner wall of the housing assembly 800. Preferably, a first bearing 911 and a second bearing 912 are installed at intervals on the inner wall of the motor housing 810. The first bearing 911 and the second bearing 912 jointly support the transmission component 910 to ensure the stability of the transmission component 910 during rotation. Of course, in other embodiments, the coupling 920 can be omitted, and the transmission component 910 can be directly fixedly connected to the motor output shaft 210.

[0041] In one embodiment, when the rotating component 500 is a lead screw nut and the linear motion component 600 is a lead screw, the transmission component 910 has a first mounting hole in the axial direction, and one end of the linear motion component 600 is connected to the second end of the crank, while the other end is disposed in the first mounting hole. In this embodiment, the transmission component 910 has a cylindrical structure, the linear motion component 600 passes through the rotating component 500 and engages with the threaded ball joint of the rotating component 500, one end of the linear motion component 600 is rotatably connected to the second end of the crank 300 (such as a hinge connection), and the other end of the linear motion component 600 is inserted into the inner cavity of the transmission component 910. By opening the first mounting hole on the transmission component 910 and placing one end of the linear motion component 600 in the first mounting hole, the linear motion component 600 is engaged with the rotating component 500 while the linear motion component 600's linear motion path is defined. This achieves guidance of the linear motion component 600 by the first mounting hole, thereby reducing the wobbling of the linear motion component 600 and improving the stability and reliability of the transmission.

[0042] Both the rotating component 500 and the transmission component 910 have flange-like structures at their mating parts, and are fixed by screws. The inner surface of the rotating component 500 and the outer surface of the linear motion component 600 are provided with threaded raceways containing balls, and a return mechanism is embedded within the rotating component 500. Thus, when the motor 200 is operating, the motor output shaft 210 drives the coupling 920, the transmission component 910, and the rotating component 500 to rotate, causing the linear motion component 600 to move linearly along the axial direction of the rotating component 500, thereby rotating the crank 300 and adjusting the height of the pedal 400. In this embodiment, the transmission component 910 has a guide portion 930, and the linear motion component 600 has a mating portion 913. The guide portion 930 and the mating portion 913 cooperate to define the movement trajectory of the linear motion component 600. In this embodiment, the guide portion 930 is a limiting block formed in the inner cavity of the transmission member 910, and the mating portion 913 is a limiting groove formed on the end face of the linear motion member 600. The limiting block has a protrusion that inserts into the limiting groove. Preferably, the limiting block is located at one end of the transmission member 910 adjacent to the motor 200 and has a T-shaped structure. The limiting block includes a horizontal portion fixedly connected to the bottom wall of the transmission member 910 and a vertical portion fixedly connected to the horizontal portion and extending along the axial direction of the transmission member 910. This vertical portion constitutes the protrusion of the limiting block. Through the cooperation of the limiting groove and the protrusion, on the one hand, the linear movement path of the linear motion member 600 (lead screw) along the axial direction of the rotating member 500 is limited, and on the other hand, the linear movement stroke of the linear motion member 600 is limited. When the rotating member 500 is a lead screw and the linear motion member 600 is a lead screw nut, both adopt a threaded ball joint. Refer to the above description of the threaded ball joint, which will not be repeated here.

[0043] Additionally, a limiting member 130 for limiting the rotation angle of the crank 300 is provided on the base plate 100 near the first end of the crank 300. A soft rubber part 131 is provided on this limiting member 130. By providing the limiting member 130 on the base plate 100 beside the first end of the crank 300, the maximum angle at which the crank 300 rotates towards the motor 200 can be limited, allowing the crank to rotate within a predetermined range. The soft rubber part 131 can be made of silicone or rubber material to reduce the impact of the limiting member 130 on the crank 300. It should also be noted that in this embodiment, the output shaft of the motor 200 is set at an angle to the base plate 100, the angle between the crank 300 and the base plate 100 is greater than the angle between the motor output shaft 210 and the base plate 100, and the pedal surface of the pedal 400 faces away from the motor 200. In this way, the pedal 400 can be stepped on from the side of the crank 300 facing away from the motor, which shortens the distance between the user's leg and the pedal 400, making it easier to step on the pedal 400. On the other hand, since the pedaling force acting on the pedal 400 is along the tangential direction of the crank 300's rotation in order to push the crank 300, by making the angle between the crank 300 and the base plate 100 greater than the angle between the motor output shaft 210 and the base plate 100, the pedal surface of the pedal 400 is made to face as far to the left of the crank 300 as possible, thereby reducing the difficulty for the user to step on the pedal 400.

[0044] This utility model also discloses a gaming device for use with computer-based racing games or driving training software, enabling users to obtain a realistic vehicle driving experience. The gaming device includes the aforementioned pedal device and a steering wheel device. The steering wheel device controls the vehicle's direction of travel in the game or driving training software, and feeds feedback to the system by detecting the steering wheel's rotation angle to adjust parameters in the software. The pedal device controls the vehicle's brakes, accelerator, etc. The structure and operating principle of the pedal device in this embodiment are completely identical to those of the aforementioned pedal device; please refer to the relevant descriptions above for details, which will not be repeated here.

[0045] The aforementioned pedal device and gaming equipment abandon the complex linkage gear structure. Instead, a simplified combination of a lead screw drive and crank 300 converts the rotation of the motor output shaft 210 into the linear motion of the linear motion component 600. This linear motion component 600 then drives the crank 300 to rotate, adjusting the position of the pedal 400. This transforms the torque output by the motor 200 into a force acting on the pedal 400, simulating the force feedback of a traditional mechanical pedal 400. Through torque adjustment of the motor 200, dynamic control of the pedal force is achieved. Its simple structure simplifies the transmission chain and spatial layout between motor torque and pedal force, reduces transmission components, lowers the risk of failure, and reduces friction and gaps between components. The response speed of converting motor torque into pedal force is improved, and the force feedback response is rapid and accurate. Its compact structure can be adapted to narrow space layouts, and has good spatial adaptability. The force transmission characteristics are stable, and the force attenuation of pedal 400 is less than or equal to 5% after long-term use, while the attenuation rate of traditional multi-link structures is about 10-15%, which improves the transmission efficiency and system reliability between motor 200 and pedal 400.
