Abstract

The application provides a game device and a pedal control mechanism thereof. The pedal control mechanism comprises a base, a first shaft, a limiting connecting plate, a first pedal, a second pedal and an angle limiting piece. The middle part of the limiting connecting plate is rotationally connected to the base through the first shaft, and the two ends of the limiting connecting plate are respectively provided with a first supporting point and a second supporting point. The limiting connecting plate is further provided with a limiting matching part. The first pedal is rotationally connected to the first supporting point. The second pedal is rotationally connected to the second supporting point. The angle limiting piece is arranged adjacent to the limiting matching part. When the spacing between the acting end of the angle limiting piece and the limiting matching part is different, the limiting connecting plate has different rotation angle ranges relative to the base.

Description

Technical Field

[0001] This application relates to the field of device simulation technology, and in particular to a gaming device and its pedal control mechanism. Background Technology

[0002] Gaming devices typically include rudders, which allow users to perform actions such as accelerating, decelerating, and rotating. However, the rotation angle range of the rudders in existing gaming devices is not adjustable, making it impossible to adapt to the rotation angle adjustment requirements of different scenarios. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a gaming device and its pedal control mechanism, which can adjust the rotation angle range to solve the above-mentioned technical problems.

[0004] In a first aspect, this application provides a pedal control mechanism, which includes:

[0005] Base;

[0006] First axis;

[0007] The limiting connecting plate has its middle part rotatably connected to the base via a first shaft. The two ends of the limiting connecting plate are respectively provided with a first fulcrum and a second fulcrum. The limiting connecting plate is also provided with a limiting mating part.

[0008] The first pedal is rotatably connected to the first fulcrum;

[0009] The second pedal is rotatably connected to the second fulcrum;

[0010] An angular limiting component is provided adjacent to the limiting mating part. When the distance between the functional end of the angular limiting component and the limiting mating part of the limiting connecting plate is different, the limiting connecting plate has different rotation angle ranges relative to the base.

[0011] Therefore, in this application, when the distance between the functional end of the angle limiting member and the limiting mating part of the limiting connecting plate increases, the rotation angle range of the limiting connecting plate relative to the base can be increased accordingly. Conversely, when the distance between the functional end of the angle limiting member and the limiting mating part of the limiting connecting plate decreases, the rotation angle range of the limiting connecting plate relative to the base can be decreased accordingly. Thus, the rotation angle range of the pedal control mechanism can be adjusted to meet the rotation angle range requirements under different usage scenarios.

[0012] In some possible embodiments of the first aspect, the angle limiting member includes an angle limiting block and an adjusting member. The angle limiting block is provided with an adjusting hole, and the adjusting member passes through and is connected to the adjusting hole. When the adjusting member extends out from the end of the adjusting hole facing the limiting mating part, the end of the adjusting member facing the limiting mating part is the working end. When the end of the adjusting member facing the limiting mating part retracts into the adjusting hole, at least a portion of the surface of the angle limiting block facing the limiting mating part is the working end.

[0013] Therefore, in this application, the angle limiting block itself is fixed, and by adjusting the extension length of the adjusting member in the adjusting hole of the angle limiting block, the distance between the working end of the angle limiting member and the limiting mating part can be adjusted. While realizing the adjustment of the rotation angle range, the angle limiting block itself can avoid interference with the structure and movement of the limiting connecting plate.

[0014] In some possible embodiments of the first aspect, there are two limiting mating parts, which are respectively disposed on both sides of the first shaft. There are two angle limiting members, which are respectively disposed corresponding to the two limiting mating parts, and the central axes of the adjusting members of the two angle limiting members intersect.

[0015] Therefore, in this application, there are two pairs of limiting mating parts and angle limiting members. The two pairs of limiting mating parts and angle limiting members face different directions and are arranged in opposite directions. One pair of limiting mating parts and angle limiting members is used to limit the rotation angle range of the limiting connecting plate in the first direction, and the other pair of limiting mating parts and angle limiting members is used to limit the rotation angle range of the limiting connecting plate in the second direction. The rotation angle range in the first direction and the rotation angle range in the second direction can be adjusted separately to adapt to the rotation angle range requirements of more scenarios.

[0016] In some possible embodiments of the first aspect, the limiting connecting plate includes an intermediate section and a first connecting arm and a second connecting arm located at both ends of the intermediate section. A U-shaped open structure is formed between the first connecting arm, the intermediate section and the second connecting arm. A first fulcrum is located on the end of the first connecting arm away from the intermediate section, and a second fulcrum is located on the end of the second connecting arm away from the intermediate section. A limiting mating part is located on the intermediate section.

[0017] Therefore, in this application, the first connecting arm, the intermediate section, and the second connecting arm form an integral U-shaped structure, which can improve bending stiffness. The U-shaped open structure, while ensuring the strength of the limiting connecting plate, can reduce material usage, achieve lightweight design, and provide clearance for other components, reducing the risk of interference. The first and second fulcrums are located at the far ends of the limiting connecting plate, forming a wide base support, which significantly improves the anti-overturning capacity. The first and second fulcrums, together with the limiting mating part on the intermediate section, form a stable triangular force system, making the load distribution more uniform and avoiding stress concentration at single points. The intermediate section can serve as an independent functional surface, facilitating the machining of high-precision limiting mating parts.

[0018] In some possible embodiments of the first aspect, the pedal control mechanism further includes:

[0019] Second axis;

[0020] The main beam is rotatably connected to the base via a second shaft in the middle, and the two ends of the main beam are respectively provided with a third support point and a fourth support point;

[0021] The first pedal is also connected to the third fulcrum;

[0022] The second pedal is also connected to the fourth fulcrum;

[0023] The main beam, the limiting connecting plate, the first pedal, and the second pedal form a parallel four-bar linkage mechanism.

[0024] When the first pedal and the second pedal are driven to rotate relative to the first shaft and the second shaft, the central axis of the first pedal and the second pedal is always parallel to the line connecting the first shaft and the second shaft.

[0025] Therefore, in this application, because the parallel four-bar linkage is constrained by the first and second axes, the orientation of the first and second pedals remains parallel to the connection direction of the first and second axes when they are driven to rotate relative to them. Thus, when the connection direction of the first and second axes is forward and backward, it ensures that the first and second pedals maintain their forward and backward orientation during rotation, without changing their orientation, thus facilitating operation.

[0026] In some possible embodiments of the first aspect, the first pedal further includes a first connecting plate and a first pedal assembly, and the second pedal includes a second connecting plate and a second pedal assembly. One end of the first connecting plate is connected to a first fulcrum and a third fulcrum, and the other end of the first connecting plate is connected to the first pedal assembly. One end of the second connecting plate is connected to a second fulcrum and a fourth fulcrum, and the other end of the second connecting plate is connected to the second pedal assembly.

[0027] Therefore, in this application, the first pedal assembly and the second pedal assembly can be installed on opposite sides of the main beam and the limiting connecting plate through the first connecting plate and the second connecting plate, so as to avoid the main beam and the limiting connecting plate interfering with the vertical movement space of the first pedal assembly and the second pedal assembly.

[0028] In some possible embodiments of the first aspect, the main beam includes an upper connecting plate, a lower connecting plate, and a plurality of connecting members. The upper connecting plate and the lower connecting plate are parallel and spaced apart, and are fixedly connected to each other by a plurality of connecting members. A limiting connecting plate is located between the upper connecting plate and the lower connecting plate and is offset from the plurality of connecting members. An angle limiting member is fixed to the upper connecting plate or the lower connecting plate.

[0029] Therefore, in this application, the upper and lower connecting plates are arranged in parallel and spaced apart to form an "I-beam"-like structure, which effectively suppresses the torsional deformation of the main beam. Multiple connecting parts are distributed and fixed, making the upper and lower connecting plates form an integral load-bearing frame and improving local stiffness. The staggered arrangement of the limiting connecting plates relative to the connecting parts avoids interference from the connecting parts when the limiting connecting plates move relative to the upper and lower connecting plates. At least a portion of the limiting connecting plates is located in the vertical space between the upper and lower connecting plates, saving installation space outside the main beam. The angle limiting parts can be selectively installed on either the upper or lower connecting plates to adapt to different working conditions.

[0030] In some possible embodiments of the first aspect, the pedal control mechanism further includes a centering mechanism, which includes a first spring plate, a second spring plate, and a spring. The first spring plate and the second spring plate are arranged opposite to each other and are rotatably connected to the base. The first spring plate has a first force-bearing part and a first connecting end at both ends, and the second spring plate has a second force-bearing part and a second connecting end at both ends. A force-applying part is provided on the main beam, which acts on the first force-bearing part and the second force-bearing part. The spring is connected between the first connecting end and the second connecting end. When the main beam rotates relative to the centerline of the base in a first direction or a second direction, the force-applying part is driven by the main beam to apply force to the first force-bearing part and the second force-bearing part to store energy in the spring. When the external force disappears, the elastic restoring force of the spring is used to drive the main beam to drive the first pedal and the second pedal back to center, wherein the first direction and the second direction are opposite.

[0031] Therefore, in this application, when the main beam rotates relative to the base from the centerline position in the first direction or in the second direction, the force-applying part applies force to the first force-receiving part and the second force-receiving part, respectively driving the first spring plate and the second spring plate to rotate around their respective axes, causing the first connecting end and the second connecting end to move in opposite directions, thereby pulling the spring and storing spring force. When the external force disappears, the elastic restoring force of the spring is used to drive the first connecting end and the second connecting end to move towards each other, and drive the first spring plate and the second spring plate to rotate in opposite directions around their respective axes. In turn, the first force-receiving part and the second force-receiving part drive the force-applying part, thereby driving the main beam to rotate. The rotation of the main beam drives the first pedal and the second pedal to return to the center, so that the first pedal and the second pedal are symmetrically arranged on opposite sides of the centerline position, realizing automatic and accurate centering, and providing convenience for actual operation.

[0032] In some possible embodiments of the first aspect, the first force-bearing part is provided with a first abutting surface, a second abutting surface and a third abutting surface connected in sequence. The first abutting surface is adjacent to the pivot of the first spring plate. The second abutting surface is recessed relative to the first abutting surface and the third abutting surface. The second force-bearing part is provided with a fourth abutting surface, a fifth abutting surface and a sixth abutting surface connected in sequence. The fifth abutting surface is recessed relative to the fourth abutting surface and the sixth abutting surface. The fourth abutting surface is adjacent to the pivot of the second spring plate. When the main beam rotates from the centerline position to the first direction, the force-applying part abuts against the first abutting surface and the sixth abutting surface. When the main beam rotates from the centerline position to the second direction, the force-applying part abuts against the third abutting surface and the fourth abutting surface. When the main beam returns to the center, the force-applying part abuts against the second abutting surface and the fifth abutting surface.

[0033] Therefore, in this application, since the second abutting surface is recessed relative to the first and third abutting surfaces, the first and third abutting surfaces are slopes, and the second abutting surface is a valley. The fifth abutting surface is recessed relative to the fourth and sixth abutting surfaces, so the fourth and sixth abutting surfaces are slopes, and the fifth abutting surface is a valley. When the main beam is driven to rotate from the centerline position in the first direction by the first and second pedals, the force-applying part rotates in the first direction along with the main beam, transitioning from contact with the second and fifth contact surfaces to contact with the first and sixth contact surfaces. As it transitions from a valley surface to a slope surface, it presses down on the first and sixth contact surfaces, causing the first and second spring plates to rotate around their respective axes, resulting in the first and second connecting ends moving in opposite directions. The springs are stretched, and after the external force is removed, the elastic restoring force of the springs pulls the first and second connecting ends to move towards each other, thereby driving the first and second spring plates to rotate in opposite directions around their respective axes. This causes the first and second force-receiving parts to push the force-applying part upward, so that the force-applying part drives the main beam to rotate in the second direction, transitioning from contact with the first and sixth contact surfaces to contact with the second and fifth contact surfaces. This pushes the main beam to drive the first and second pedals back to the center, that is, the first and second pedals are symmetrically located on both sides of the centerline position of the base. Conversely, when the main beam is driven to rotate from the centerline to the second direction via the first and second pedals, the force-applying part rotates in the second direction along with the main beam, transitioning from contact with the second and fifth contact surfaces to contact with the third and fourth contact surfaces. Because the transition is from a valley surface to a slope, the third and fourth contact surfaces are pressed down, causing the first and second spring plates to rotate around their respective axes, resulting in the first and second connecting ends moving in opposite directions. The springs are stretched, and after the external force is removed, the elastic restoring force of the springs pulls the first connecting end... The first and second connecting ends move towards each other, thereby driving the first and second spring plates to move around their respective rotation axes. This causes the first and second force-bearing parts to push the force-applying part upwards, so that the force-applying part drives the main beam to rotate in the first direction, transitioning from contact with the third and fourth contact surfaces to contact with the second and fifth contact surfaces. This pushes the main beam to drive the first and second pedals back to center, achieving accurate centering. Moreover, the force-applying part can simultaneously drive the first and second force-bearing parts, resulting in a simple, compact structure with better synchronization.

[0034] Secondly, this application provides a gaming device, which includes the pedal control mechanism described in the first aspect.

[0035] The beneficial effects of the second aspect of the gaming device are the same as those of the first aspect of the pedal control mechanism, and will not be elaborated further. Attached Figure Description

Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0050] In the description of this application, the terms "first," "second," etc. are used to distinguish different objects, rather than to describe a specific order. The terms "upper," "lower," "inner," "outer," etc., which indicate the orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] In the description of this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal connection of two components; it can be a communication connection; or it can be an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the modules of the game device 1000 in this embodiment. The game device 1000 may be a flight simulator, a racing simulator, a tank / armored vehicle simulator, an engineering machinery simulator, a space capsule / spaceship simulator, a ship steering simulator, a medical and surgical simulator, an industrial and robot operation simulator, etc. In this embodiment, the game device 1000 is a flight simulator, including a simulator cockpit 1001, a motion system 1002, a visual system 1003, a computer system 1004, and auxiliary equipment 1005.

[0053] The simulator cockpit 1001 includes control devices, instruments, and other equipment. The control devices, including the joystick, throttle lever, and pedal control mechanism 100, are similar to those of a real aircraft, allowing players to perform operations such as takeoff, climb, turn, and landing, simulating realistic flight control. Instruments include an airspeed indicator, altimeter, headroom indicator, attitude indicator, turn coordination indicator, and vertical speed indicator, displaying information such as flight speed, altitude, direction, and attitude to help players understand the aircraft's flight status. Other equipment includes a seat and a switch panel. The seat is adjustable to simulate the physical sensations under different flight attitudes, and the switch panel is used to control various flight systems and equipment.

[0054] The motion system 1002 includes a drive unit. The drive unit uses a hydraulic servo actuator or an electric actuator. By controlling the extension and retraction of the actuator, it drives the simulated cockpit 1001 to move, achieving 3-DOF or 6-DOF motion, allowing the player's body to feel the aircraft's movement changes. The 3-DOF includes pitch, roll, and yaw, enabling pitch, roll, and yaw movements, allowing the player to feel the aircraft's pitch, roll, and yaw. The 6-DOF, in addition to the 3-DOF, adds linear displacement in the forward, backward, left, right, and up / down directions, more realistically simulating various aircraft motion states in the air.

[0055] The visual system 1003 includes image generation and display devices. Image generation utilizes computer graphics technology to generate realistic 3D scenes and images based on calculations from flight simulation software. These include terrain, buildings, clouds, weather effects, and can simulate different weather conditions such as day / night cycles, sunny days, rainy days, and foggy days. Display devices include projectors, large-screen displays, or VR (Virtual Reality) headsets to display the generated images, providing players with a wide field of view and showcasing the external scenery of the aircraft, such as airports, runways, cities, mountains, and oceans, making players feel as if they are in a realistic flight environment.

[0056] Computer system 1004 includes hardware and flight simulation software. The hardware includes one or more high-performance computers to meet the operational requirements of the flight simulation software, processing large amounts of flight data and handling graphics rendering tasks. The flight simulation software contains mathematical models, aerodynamic models, and flight control system models of the aircraft. Based on the player's actions and flight status, it calculates the aircraft's trajectory, attitude changes, instrument data, etc., in real time and feeds the results back to other systems, achieving real-time performance and accuracy in flight simulation.

[0057] Auxiliary equipment 1005 includes an audio system and a lighting system. The audio system includes speakers or headphones that play sounds such as the roar of the aircraft engine, wind noise, landing gear retraction and extension sounds, and communication sounds, enhancing the realism and immersion of the flight and making the player feel more present. The lighting system simulates the lighting effects inside the aircraft cockpit, such as instrument lights, cabin lighting, and signal lights, as well as external airport lights and runway lights. It adjusts according to flight status and environmental changes, providing the player with a more realistic visual experience.

[0058] Please refer to Figure 2 , Figure 2 This is a three-dimensional structural diagram of the pedal control mechanism 100 according to an embodiment of this application. For ease of description, the following definitions are used. Figure 2 The front-to-back direction of the pedal control mechanism 100 shown is the Y-axis direction, i.e., the thickness direction and the front-to-back direction, defined as follows: Figure 2 The left-right direction of the pedal control mechanism 100 shown is the X-axis direction, i.e., the length direction and the horizontal direction. The direction perpendicular to both the X-axis and the Y-axis direction is defined as the Z-axis direction, the vertical direction. The directional terms such as "top," "bottom," "left," and "right" used in the description of the pedal control mechanism 100 in this application are based on the accompanying drawings. Figure 2The description of the orientation shown uses the positive direction of the Z-axis as "top" and the negative direction of the Z-axis as "bottom". Specifically, the side where the base 10 is located is the bottom, the side where the main beam 80 is located is the top, the negative direction of the X-axis is "left", the positive direction of the X-axis is "right", the negative direction of the Y-axis is "rear", and the positive direction of the Y-axis is "front". It does not constitute a limitation on the pedal control mechanism 100 in actual application scenarios.

[0059] It should be noted that when the pedal control mechanism 100 is applied to a flight simulator, it can be used to simulate left turns, right turns, and throttle control. For example, rotating the pedal counterclockwise enables left turn control, rotating it clockwise enables right turn control, and pressing the pedal down enables throttle control. It is understood that when the pedal control mechanism 100 is applied to other simulators, it can achieve different operational controls, which are not limited here.

[0060] Please refer to Figure 2 The pedal control mechanism 100 includes:

[0061] Base 10;

[0062] First axis 20;

[0063] The limiting connecting plate 30 is rotatably connected to the base 10 through the first shaft 20 in the middle. The two ends of the limiting connecting plate 30 are respectively provided with a first fulcrum 31 and a second fulcrum 32. The limiting connecting plate 30 is also provided with a limiting mating part 33.

[0064] The first pedal 40 is rotatably connected to the first fulcrum 31;

[0065] The second pedal 50 is rotatably connected to the second fulcrum 32;

[0066] An angular limiting member 60 is provided adjacent to the limiting mating part 33, and the distance between the functional end of the angular limiting member 60 and the limiting mating part 33 is different.

[0067] Therefore, in this application, when the distance between the functional end of the angle limiting member 60 and the limiting mating part 33 of the limiting connecting plate 30 increases, the rotation angle range of the limiting connecting plate 30 relative to the base 10 can be increased accordingly. Conversely, when the distance between the functional end of the angle limiting member 60 and the limiting mating part 33 of the limiting connecting plate 30 decreases, the rotation angle range of the limiting connecting plate 30 relative to the base 10 can be decreased accordingly. Thus, the rotation angle range of the first pedal 40 and the second pedal 50 can be adjusted to meet the rotation angle range requirements under different usage scenarios.

[0068] In some embodiments, the first shaft 20 can be fixed on the base 10, and the limiting connecting plate 30 is provided with a corresponding shaft hole.

[0069] In other embodiments, the first shaft 20 can be fixed on the limiting connecting plate 30, and the base 10 is provided with a corresponding shaft hole.

[0070] In some embodiments, the rotation angle range of the limiting connecting plate 30 relative to the base 10 is the rotation angle range of the pedal control mechanism 100. The maximum rotation angle range of the pedal control mechanism 100 is [-a, +b], where a and b can be 30 degrees, that is, the maximum counterclockwise rotation angle is 30 degrees, and the maximum clockwise rotation angle is 30 degrees. In other embodiments, the values ​​of a and b can be adjusted according to actual needs. Within the maximum rotation angle range, the rotation angle range can be further limited by the cooperation of the limiting connecting plate 30 and the angle limiting member 60. For example, in the first scenario, the rotation angle range of the pedal control mechanism 100 is limited to [-20, +20], in the second scenario, the rotation angle range of the pedal control mechanism 100 is limited to [-25, +20], and in the third scenario, the rotation angle range of the pedal control mechanism 100 is limited to [-20, +30], etc. There are no specific limitations here, and the specific range can be set according to the actual scenario needs.

[0071] In some embodiments, when the distance between the functional end of the angle limiting member 60 and the limiting mating part 33 decreases, the rotation angle range of the limiting connecting plate 30 relative to the base 10 will narrow; conversely, when the distance between the functional end of the angle limiting member 60 and the limiting mating part 33 increases, the rotation angle range of the limiting connecting plate 30 relative to the base 10 will widen. For example, when the distance between the functional end of the angle limiting member 60 and the limiting mating part 33 is a first distance, the rotation angle range of the limiting connecting plate 30 relative to the base 10 is -30 to 30 degrees; when the distance between the functional end of the angle limiting member 60 and the limiting mating part 33 is a second distance, the rotation angle range of the limiting connecting plate 30 relative to the base 10 is -20 to 20 degrees, wherein the first distance is greater than the second distance.

[0072] Therefore, in this application, by adjusting the distance between the working end of the angle limiting member 60 and the limiting mating part 33, the rotation angle range of the limiting connecting plate 30 relative to the base 10 can be adjusted according to the needs of the scenario, thereby adjusting the rotation angle range of the pedal control mechanism 100.

[0073] In some embodiments, please refer to Figure 3 and Figure 4 , Figure 3 This is a three-dimensional structural diagram of the angle limiting member 60 in one direction in an embodiment of this application. Figure 4This is a three-dimensional structural diagram of the angle limiting member 60 in another direction according to an embodiment of this application. The angle limiting member 60 includes an angle limiting block 61 and an adjusting member 62. The angle limiting block 61 is provided with an adjusting hole 611. The adjusting member 62 passes through and is connected to the adjusting hole 611. When the adjusting member 62 extends out from the end of the adjusting hole 611 facing the limiting fitting part 33, the end of the adjusting member 62 facing the limiting fitting part 33 is the working end. When the end of the adjusting member 62 facing the limiting fitting part 33 retracts into the adjusting hole 611, at least a portion of the surface of the angle limiting block 61 facing the limiting fitting part 33 is the working end.

[0074] Therefore, in this application, the angle limiting block 61 itself is fixed, and the distance between the working end of the angle limiting member 60 and the limiting mating part 33 can be adjusted by adjusting the extension length of the adjusting member 62 in the adjusting hole 611 of the angle limiting block 61. While realizing the adjustment of the rotation angle range of the limiting connecting plate 30 relative to the base 10, the angle limiting member 60 itself can avoid interference with the structure and movement of the limiting connecting plate 30.

[0075] from Figure 3 and Figure 4 As can be seen, the angle limiting block 61 is block-shaped and has a threaded hole in the vertical direction (Z-axis direction) for fixing the angle limiting block 61 itself through a threaded connector. It is understood that the angle limiting block 61 can be fixed to the base 10 or other structures of the pedal control mechanism 100, which is not limited here.

[0076] from Figure 3 and Figure 4 As can be seen, the angle limiting block 61 has a protrusion 612 at the position corresponding to the adjustment hole 611, thereby increasing the thickness dimension of the angle limiting block 61. The adjustment hole 611 is provided through the angle limiting block 61 at the position with the protrusion 612, which increases the length of the adjustment hole 611, thereby increasing the threaded connection length between the adjustment hole 611 and the adjusting member 62, reducing the risk of thread stripping. The protrusion 612 forms a locally thickened structure, improving the deformation resistance of the angle limiting block 61 in this area, thereby enhancing structural stability. Moreover, as a stress diffusion structure, the protrusion 612 can effectively reduce concentrated stress, resulting in a more uniform force distribution, avoiding stress singularities at the root of the thread, and optimizing the force transmission path. In addition, extending the threaded connection length can prevent axial movement during the adjustment process.

[0077] In some embodiments, the adjusting member 62 includes a screw head 621, a screw 622, and a nut 623. The screw head 621 is located on one side of the angle limiting block 61, and the nut 623 is located on the other side of the angle limiting block 61. The screw 622 connects to the screw head 621 and passes through the adjusting hole 611 to be threadedly connected to the nut 623.

[0078] It is understandable that the nut 623 is a blind hole nut. Therefore, the end face of the nut 623 can be used as the working end, and has a contact plane facing the limiting fit part 33, which can abut against the limiting fit part 33.

[0079] In some embodiments, the angle limiting block 61 has a receiving hole 613 at one end facing the limiting mating part 33. The receiving hole 613 is coaxially arranged with the adjusting hole 611, and the inner diameter of the receiving hole 613 is larger than the inner diameter of the adjusting hole 611, so as to receive the nut 623.

[0080] Therefore, in extreme cases, the nut 623 can be directly received in the receiving hole 613. In this case, the entire surface of the angle limiting block 61 facing the limiting mating part 33 can be used as the working end to cooperate with the limiting mating part 33 to realize the angle limiting function.

[0081] Please refer to Figure 5 , Figure 5 for Figure 2 A partial enlarged view of point A. In this embodiment, there are two limiting fitting parts 33, which are respectively provided on both sides of the rotating shaft of the limiting connecting plate 30. There are two angle limiting members 60, which are respectively provided corresponding to the two limiting fitting parts 33, and the central axes of the adjusting members 62 of the two angle limiting members 60 intersect.

[0082] Therefore, in this application, there are two pairs of limiting mating parts 33 and angle limiting members 60. The two pairs of limiting mating parts 33 and angle limiting members 60 face different directions and are arranged in opposite directions. One pair of limiting mating parts 33 and limiting connecting plate 30 is used to limit the rotation angle range of the limiting connecting plate 30 in the first direction, and the other pair of limiting mating parts 33 and limiting connecting plate 30 is used to limit the rotation angle range of the limiting connecting plate 30 in the second direction. The rotation angle range in the first direction and the rotation angle range in the second direction can be adjusted separately and can be different from each other, thereby realizing the adjustment of the rotation angle range of the pedal control mechanism 100 to adapt to the rotation range adjustment in more scenarios.

[0083] In some embodiments, the first direction is counterclockwise and the second direction is clockwise. In other embodiments, the first direction is clockwise and the second direction is counterclockwise; this is not limited here.

[0084] Therefore, in this application, by means of two pairs of limiting mating parts 33 and angle limiting parts 60, the rotation angle ranges of the first pedal 40 and the second pedal 50 in the first direction and the second direction can be limited respectively, so that the first direction and the second direction can have different rotation angle ranges respectively, so as to adapt to the rotation angle range requirements of more scenarios.

[0085] In some embodiments, the limiting mating part 33 is an abutting plane, and the functional end of the angle limiting member 60 is also an abutting plane. The abutting plane of the limiting mating part 33 and the abutting plane of the functional end of the angle limiting member 60 are parallel to each other, and the abutting plane of the limiting mating part 33 is perpendicular to the central axis of the adjusting member 62 of the corresponding angle limiting member 60.

[0086] Therefore, in this application, the contact area between the abutting plane of the limiting mating part 33 and the abutting plane of the functional end of the angle limiting member 60 is increased, thereby improving the abutting stability. Simultaneously, the rotation angle range of the connecting plate 30 in the first direction is limited by the abutting planes of one pair of limiting mating parts 33 and the abutting plane of the angle limiting member 60, while the rotation angle range of the limiting connecting plate 30 in the second direction is limited by the abutting planes of the other pair of limiting mating parts 33 and the abutting plane of the angle limiting member 60. Thus, different rotation angle ranges can be achieved in the two directions to adapt to more application scenarios.

[0087] In some embodiments, please refer again Figure 2 The limiting connecting plate 30 includes an intermediate section 34 and a first connecting arm 35 and a second connecting arm 36 located at both ends of the intermediate section 34. A U-shaped open structure is formed between the first connecting arm 35, the intermediate section 34 and the second connecting arm 36. The first fulcrum 31 is located on the end of the first connecting arm 35 away from the intermediate section 34, and the second fulcrum 32 is located on the end of the second connecting arm 36 away from the intermediate section 34. The limiting mating part 33 is located on the intermediate section 34.

[0088] Therefore, in this application, the first connecting arm 35, the intermediate section 34, and the second connecting arm 36 form an integral U-shaped structure, improving bending stiffness. The U-shaped open structure, while ensuring the strength of the limiting connecting plate 30, reduces material usage, achieving a lightweight design, and provides clearance for other components, reducing interference risks. The first fulcrum 31 and the second fulcrum 32 are located at the far ends of the limiting connecting plate 30, forming a wide base support, significantly improving overturning resistance. The first fulcrum 31 and the second fulcrum 32, together with the limiting mating part 33 on the intermediate section 34, form a stable triangular force system, making the load distribution more uniform and avoiding single-point stress concentration. The intermediate section 34, as an independent functional surface, facilitates the machining of the high-precision limiting mating part 33.

[0089] In some embodiments, the limiting connecting plate 30 is an integral structure, while in other embodiments, the limiting connecting plate 30 is a separate structure; this is not limited here.

[0090] In some embodiments, please refer again Figure 2 The pedal control mechanism 100 also includes:

[0091] Second axis 70;

[0092] The main beam 80 is rotatably connected to the base 10 via the second shaft 70 in the middle. The two ends of the main beam 80 are respectively provided with a third support point 81 and a fourth support point 82.

[0093] The first pedal 40 is also connected to the third fulcrum 81;

[0094] The second pedal 50 is also connected to the fourth fulcrum 82;

[0095] The main beam 80, the limiting connecting plate 30, the first pedal 40 and the second pedal 50 form a parallel four-bar linkage structure;

[0096] When the first pedal 40 and the second pedal 50 are driven to rotate relative to the first shaft 20 and the second shaft 70, the central axis of the first pedal 40 and the second pedal 50 is always parallel to the line connecting the first shaft 20 and the second shaft 70.

[0097] The central axis of the first pedal 40 and the second pedal 50 refers to the axis of symmetry of the first pedal 40 and the second pedal 50. Of course, in some embodiments, when the first pedal 40 and the second pedal 50 are asymmetrical structures, the central axis of the first pedal 40 and the second pedal 50 can be the midline reference line of the first pedal 40.

[0098] Therefore, in this application, because the parallel four-bar linkage is constrained by the first shaft 20 and the second shaft 70, when the first pedal 40 and the second pedal 50 are driven to rotate relative to the first shaft 20 and the second shaft 70, the orientation of the first pedal 40 and the second pedal 50 remains parallel to the connection direction of the first shaft 20 and the second shaft 70. Thus, when the connection direction of the first shaft 20 and the second shaft 70 is a front-back direction, it can be ensured that the first pedal 40 and the second pedal 50 maintain their front-back direction during rotation and do not change their orientation with rotation, facilitating operation.

[0099] In some embodiments, the first line connecting the first fulcrum 31 and the first shaft 20 is parallel to the second line connecting the third fulcrum 81 and the second shaft 70; the third line connecting the second fulcrum 32 and the first shaft 20 is parallel to the fourth line connecting the fourth fulcrum 82 and the second shaft 70; the fifth line connecting the third fulcrum 81 and the first fulcrum 31, the sixth line connecting the fourth fulcrum 82 and the second fulcrum 32, and the seventh line connecting the first shaft 20 of the limiting connecting plate 30 and the second shaft 70 of the main beam 80 are parallel to each other; and the first line connecting the first fulcrum 31 and the first shaft 20 and the third line connecting the second fulcrum 32 and the first shaft 20 intersect at a V-shaped angle; the second line connecting the third fulcrum 81 and the second shaft 70 and the fourth line connecting the fourth fulcrum 82 and the second shaft 70 intersect at a V-shaped angle.

[0100] In some embodiments, the included angles of the two sets of V-shapes are the same and the angle range is 55°±5°. In other embodiments, the angle range of the two sets of V-shapes can be other angle ranges, which are not limited here.

[0101] Therefore, in this application, the parallel four-bar linkage structure formed by the main beam 80, the limiting connecting plate 30, the first pedal 40, and the second pedal 50 has two sets of V-shaped angles, which can offset most of the torsional moment. The fifth line connecting the third fulcrum 81 and the first fulcrum 31, the sixth line connecting the fourth fulcrum 82 and the second fulcrum 32, and the seventh line connecting the first axis 20 of the limiting connecting plate 30 and the second axis 70 of the main beam 80 are parallel to each other, which can eliminate unexpected degrees of freedom and enhance motion accuracy. The parallel four-bar linkage is constrained by the first axis 20 and the second axis 70, and the first fulcrum 31, the second fulcrum 32, the third fulcrum 81, and the fourth fulcrum 82 are suspended and supported, which significantly improves the dynamic stiffness and optimizes the load distribution. Moreover, the fifth, sixth, and seventh lines form a statically indeterminate structure, which improves the impact resistance and enhances the stability of the mechanism. Compared with the traditional parallel four-bar linkage, the envelope space of the parallel four-bar linkage with two sets of V-shaped angles is greatly reduced, realizing compact force transmission and improving the structural compactness of the pedal control mechanism 100. Moreover, by increasing or decreasing the number of V-angles in the parallel four-bar linkage, it can be adapted to different load levels.

[0102] In some embodiments, please refer again Figure 5 The intermediate section 34 also includes a connecting part 341, which is located between the two limiting mating parts 33 and is offset relative to the main beam 80. It is used to bypass the main beam 80 and directly connect to the base 10 via the first shaft 20. The two limiting mating parts 33 are inclined relative to the connecting part 341, thus forming a U-shaped open structure.

[0103] In some embodiments, please refer again Figure 2 The first connecting arm 35 and the second connecting arm 36 are S-shaped. The first connecting arm 35 is connected to one end of the limiting fitting part 33 opposite to the connecting part 341, and the second connecting arm 36 is connected to one end of the limiting fitting part 33 opposite to the connecting part 341. At least a portion of the first connecting arm 35 and the second connecting arm 36 are located in the vertical space of the main beam 80, and the other portion extends out relative to the main beam 80.

[0104] Therefore, the first connecting arm 35 and the second connecting arm 36 can effectively avoid structural components within the main beam 80, while also improving the overall torsional stiffness of the limiting connecting plate 30.

[0105] In some embodiments, the second shaft 70 is located between the two adjacent ends of the two angle limiting blocks 61, and the second shaft 70 passes through the main beam 80 and is connected to the base 10.

[0106] Thus, the first shaft 20 and the second shaft 70 are located at different positions on the base 10, and the limiting connecting plate 30 and the main beam 80 can rotate around the first shaft 20 and the second shaft 70 respectively, without any interference between them.

[0107] In some embodiments, please refer again Figure 2 The first pedal 40 also includes a first connecting plate 41 and a first pedal assembly 42. The second pedal 50 includes a second connecting plate 51 and a second pedal assembly 52. ​​One end of the first connecting plate 41 is connected to a first fulcrum 31 and a third fulcrum 81, and the other end of the first connecting plate 41 is connected to the first pedal assembly 42. One end of the second connecting plate 51 is connected to a second fulcrum 32 and a fourth fulcrum 82, and the other end of the second connecting plate 51 is connected to the second pedal assembly 52.

[0108] The first connecting plate 41 may be provided with a first connecting hole, a second connecting hole, and a third connecting hole 413 at intervals. The first connecting hole corresponds to the first fulcrum 31 and is used to connect with the first fulcrum 31 of the limiting connecting plate 30. The second connecting hole corresponds to the third fulcrum 81 and is used to connect with the third fulcrum 81 of the main beam 80. The third connecting hole 413 corresponds to the first pedal assembly 42 and is used to connect with the first pedal assembly 42. It is understood that there are at least two third connecting holes 413, but this is not limited. When there are multiple third connecting holes 413, the connection stability between the first pedal assembly 42 and the first connecting plate 41 can be improved.

[0109] Similarly, the second connecting plate 51 may be provided with a fourth connecting hole, a fifth connecting hole, and a sixth connecting hole 513 at intervals. The fourth connecting hole corresponds to the second fulcrum 32 and is used to connect with the second fulcrum 32 of the limiting connecting plate 30. The fifth connecting hole corresponds to the fourth fulcrum 82 and is used to connect with the fourth fulcrum 82 of the main beam 80. The sixth connecting hole 513 corresponds to the second pedal assembly 52 and is used to connect with the second pedal assembly 52. ​​It is understood that there are at least two sixth connecting holes 513, but this is not limited here. When there are multiple sixth connecting holes 513, the connection stability between the second pedal assembly 52 and the second connecting plate 51 can be improved.

[0110] Therefore, in this application, the first pedal assembly 42 and the second pedal assembly 52 can be installed on opposite sides of the main beam 80 and the limiting connecting plate 30 through the first connecting plate 41 and the second connecting plate 51, so as to avoid the main beam 80 and the limiting connecting plate 30 interfering with the vertical movement space of the first pedal assembly 42 and the second pedal assembly 52.

[0111] Please refer to Figure 6 and Figure 7 , Figure 6 This is a three-dimensional structural diagram of the pedal control mechanism 100 in the embodiments of this application. Figure 7 This is a perspective view of the pedal control mechanism 100 in another direction in an embodiment of this application.

[0112] like Figure 6 and Figure 7 As shown, the main beam 80 includes an upper connecting plate 83, a lower connecting plate 84, and multiple connectors 85. The upper connecting plate 83 and the lower connecting plate 84 are parallel and spaced apart, and are fixedly connected by multiple connectors 85. The limiting connecting plate 30 is located between the upper connecting plate 83 and the lower connecting plate 84, and is offset from the multiple connectors 85. The angle limiting member 60 is fixed on the upper connecting plate 83 or the lower connecting plate 84.

[0113] Therefore, in this application, the upper connecting plate 83 and the lower connecting plate 84 are arranged in parallel and spaced apart to form an "I-beam"-like structure, which effectively suppresses the torsional deformation of the main beam 80. Multiple connecting parts 85 are distributed and fixed, making the upper connecting plate 83 and the lower connecting plate 84 form an overall load-bearing frame, improving local stiffness. The limiting connecting plate 30 is staggered relative to the connecting parts 85, which can prevent the limiting connecting plate 30 from being interfered with by the connecting parts 85 when it moves relative to the upper connecting plate 83 and the lower connecting plate 84. At least a portion of the limiting connecting plate 30 is located in the vertical space between the upper connecting plate 83 and the lower connecting plate 84, saving installation space outside the main beam 80. The angle limiting part 60 can be selectively installed on the upper connecting plate 83 or the lower connecting plate 84 to adapt to different working conditions.

[0114] In some embodiments, please refer to Figure 8 , Figure 8 for Figure 7 A partial enlarged view at point B. Each connector 85 includes a first screw 851, a columnar nut 852, and a second screw 853. The columnar nut 852 has a threaded hole that runs vertically through it. The upper connecting plate 83 and the lower connecting plate 84 have a first through hole and a second through hole at corresponding positions, respectively. The columnar nut 852 is located between the upper connecting plate 83 and the lower connecting plate 84. The first screw 851 passes through the first through hole on the upper connecting plate 83 from above and is threaded to the upper end of the threaded hole of the nut 853. The second screw 853 passes through the second through hole on the lower connecting plate 84 from below and is threaded to the lower end of the threaded hole of the nut 853.

[0115] Therefore, by having the columnar nut 852 abut against the upper connecting plate 83 and the lower connecting plate 84, this application can further improve the overall stiffness of the "I-beam" structure formed by the upper connecting plate 83 and the lower connecting plate 84.

[0116] Please refer to Figure 9 , Figure 9 This is a top view of the base 10, the centering mechanism 90, and the damping mechanism 101 in the embodiments of this application.

[0117] like Figure 9 As shown, the pedal control mechanism 100 also includes a centering mechanism 90, which includes a first spring plate 91, a second spring plate 92, and a spring 93. The first spring plate 91 and the second spring plate 92 are arranged opposite to each other and are rotatably connected to the base 10. The first spring plate 91 has a first force-bearing part 911 and a first connecting end 912 at both ends, and the second spring plate 92 has a second force-bearing part 921 and a second connecting end 922 at both ends. The main beam 80 is provided with a force-applying part 88, which is used to apply force to the first force-bearing part. The main beam 80 is connected between the first connecting end 912 and the second connecting end 922. When the main beam 80 rotates relative to the centerline of the base 10 in the first direction or in the second direction, the force-applying part 88 is driven by the main beam 80 to apply force to the first force-applying part 911 and the second force-applying part 921 to store force for the spring 93. When the external force disappears, the elastic restoring force of the spring 93 is used to drive the main beam 80 to drive the first pedal 40 and the second pedal 50 back to the center, wherein the first direction and the second direction are opposite.

[0118] In some embodiments, the first direction is counterclockwise and the second direction is clockwise. In other embodiments, the first direction is clockwise and the second direction is counterclockwise; this is not limited here.

[0119] Among them, the position of the center line is as follows Figure 9 As shown, the axis of symmetry of the base 10 is parallel to the Y-axis. It can be understood that in some other embodiments, when the base 10 has an asymmetrical structure, the centerline position can be a central reference line on the base 10 that is parallel to the Y-axis.

[0120] Therefore, in this application, when the main beam 80 rotates relative to the base 10 from the centerline position in the first direction or in the second direction, the force-applying part 88 applies force to the first force-receiving part 911 and the second force-receiving part 921, thereby driving the first spring plate 91 and the second spring plate 92 to rotate around their respective axes, causing the first connecting end 912 and the second connecting end 922 to move in opposite directions, thereby pulling the spring 93 and storing force for the spring 93. When the external force disappears, the elastic restoring force of the spring 93 is used to drive the first connecting end 912 and the second connecting end 922 to move towards each other, and drive the first spring plate 91 and the second spring plate 92 to rotate in opposite directions around their respective axes. Then, the force-applying part 88 is driven by the first force-receiving part 911 and the second force-receiving part 921, so that the force-applying part 88 drives the main beam 80 to rotate. The rotation of the main beam 80 drives the first pedal 40 and the second pedal 50 to return to the center, so that the first pedal 40 and the second pedal 50 are symmetrically arranged on opposite sides of the centerline position, realizing automatic and accurate centering, and providing convenience for actual operation.

[0121] In some embodiments, please refer to Figure 10 , Figure 10 for Figure 9 A partial enlarged view at point C. The first force-bearing part 911 has a first abutting surface 911a, a second abutting surface 911b and a third abutting surface 911c connected in sequence. The first abutting surface 911a is adjacent to the pivot of the first spring plate 91. The second abutting surface 911b is recessed relative to the first abutting surface 911a and the third abutting surface 911c. The second force-bearing part 921 has a fourth abutting surface 921a, a fifth abutting surface 921b and a sixth abutting surface 921c connected in sequence. The fifth abutment surface 921b is recessed relative to the fourth abutment surface 921a and the sixth abutment surface 921c. The fourth abutment surface 921a is adjacent to the pivot of the second spring plate 92. When the main beam 80 rotates in the first direction, the force-applying part 88 abuts against the first abutment surface 911a and the sixth abutment surface 921c. When the main beam 80 rotates in the second direction, the force-applying part 88 abuts against the third abutment surface 911c and the fourth abutment surface 921a. When the main beam 80 returns to center, the force-applying part 88 abuts against the second abutment surface 911b and the fifth abutment surface 921b. The first direction and the second direction are opposite.

[0122] In some embodiments, the first direction is counterclockwise and the second direction is clockwise. In other embodiments, the first direction is clockwise and the second direction is counterclockwise; this is not limited here.

[0123] Therefore, in this application, since the second abutting surface 911b is recessed compared to the first abutting surface 911a and the third abutting surface 911c, the first abutting surface 911a and the third abutting surface 911c are sloped surfaces, and the second abutting surface 911b is a valley surface. The fifth abutting surface 921b is recessed compared to the fourth abutting surface 921a and the sixth abutting surface 921c, so the fourth abutting surface 921a and the sixth abutting surface 921c are sloped surfaces, and the fifth abutting surface 921b is a valley surface. When the main beam 80 is driven to rotate from the centerline position in the first direction by the first pedal 40 and the second pedal 50, the force-applying part 88 rotates in the first direction along with the main beam 80, transitioning from contact with the second contact surface 911b and the fifth contact surface 921b to contact with the first contact surface 911a and the sixth contact surface 921c. Due to the transition from a valley surface to a slope surface, the first contact surface 911a and the sixth contact surface 921c are pressed down, causing the first spring plate 91 and the second spring plate 92 to rotate around their respective axes, resulting in the first connecting end 912 and the second connecting end 922 moving in opposite directions. The spring 93 is stretched, and after the external force is removed, the elasticity of the spring 93 is restored. The force pulls the first connecting end 912 and the second connecting end 922 to move towards each other, thereby driving the first spring plate 91 and the second spring plate 92 to rotate in opposite directions around their respective axes. This causes the first force-receiving part 911 and the second force-receiving part 921 to push the force-applying part 88 upward, so that the force-applying part 88 drives the main beam 80 to rotate in the second direction, transitioning from abutting against the first abutting surface 911a and the sixth abutting surface 921c to the second abutting surface 911b and the fifth abutting surface 921b. This pushes the main beam 80 to drive the first pedal 40 and the second pedal 50 back to the center. That is, the first pedal 40 and the second pedal 50 are symmetrically arranged on both sides of the center line of the base 10.Conversely, when the main beam 80 is driven to rotate from the centerline position in the second direction by the first pedal 40 and the second pedal 50, the force-applying part 88 rotates in the second direction along with the main beam 80, transitioning from contact with the second contact surface 911b and the fifth contact surface 921b to contact with the third contact surface 911c and the fourth contact surface 921a. Since the transition is from a valley surface to a slope surface, the third contact surface 911c and the fourth contact surface 921a are pressed down, causing the first spring plate 91 and the second spring plate 92 to rotate around their respective axes, resulting in the first connecting end 912 and the second connecting end 922 moving in opposite directions. The spring 93 is stretched. After the external force is removed, the elastic restoring force of the spring 93 pulls the first connecting end 91... 2. The second connecting end 922 moves towards each other, thereby driving the first spring plate 91 and the second spring plate 92 to move around their respective rotation axes. This causes the first force-receiving part 911 and the second force-receiving part 921 to push the force-applying part 88 upward, so that the force-applying part 88 drives the main beam 80 to rotate in the first direction, transitioning from abutting against the third abutting surface 911c and the fourth abutting surface 921a to abutting against the second abutting surface 911b and the fifth abutting surface 921b. This pushes the main beam 80 to drive the first pedal 40 and the second pedal 50 back to center, achieving accurate centering. Moreover, the force-applying part 88 can simultaneously drive the first force-receiving part 911 and the second force-receiving part 921, resulting in a simple and compact structure with better synchronization.

[0124] In some embodiments, please refer to Figure 8 The force-applying part 88 includes a connecting nut 881, a bushing 882, and a bearing 883. The connecting nut 881 is connected to the lower connecting plate 84, the bushing 882 is connected to the connecting nut 881, and the bearing 883 is connected to the bushing 882.

[0125] Therefore, there is relative movement between the bearing 883 and the bushing 882, so there is rolling friction between the force-applying part 88 and the first force-receiving part 911 and the second force-receiving part 921, which reduces the frictional force.

[0126] In some embodiments, there are two bearings 883, corresponding to the first force-bearing part 911 and the second force-bearing part 921 respectively. In this way, the bearings 883 and the first force-bearing part 911 and the second force-bearing part 921 are all rolling friction, which reduces friction.

[0127] In some embodiments, please refer to Figure 9 The first connecting end 912 is provided with a first hook 912a, the second connecting end 922 is provided with a second hook 922a, and the spring 93 is connected between the first hook 912a and the second hook 922a.

[0128] Thus, the connection between the spring 93 and the first connecting end 912 and the second connecting end 922 is achieved through the first hook 912a and the second hook 922a.

[0129] It is understandable that the number of first hooks 912a is not limited to one, the number of second hooks 922a is not limited to one, and the number of springs 93 is not limited to one. The number of first hooks 912a, second hooks 922a and springs 93 are set in a one-to-one correspondence.

[0130] In this embodiment, the first connecting end 912 is provided with two first hooks 912a, and the second connecting end 922 is provided with two second hooks 922a. The distance between one pair of first hooks 912a and second hooks 922a is smaller than the distance between another pair of first hooks 912a and second hooks 922a. There are two springs of unequal length, which are respectively connected between one pair of first hooks 912a and second hooks 922a and between another pair of first hooks 912a and second hooks 922a.

[0131] Therefore, in this application, two springs 93 are provided between the first connecting end 912 and the second connecting end 922. When one spring 93 breaks, the other spring 93 can still maintain more than 60% of its function, which improves the reliability of the centering mechanism 90. Moreover, the two springs 93 can provide a greater centering force and a faster centering speed.

[0132] In some embodiments, the first spring plate 91 includes a first extension arm 913 and a second extension arm 914. The proximal ends of the first extension arm 913 and the second extension arm 914 are connected and arranged substantially perpendicularly. The pivot of the first spring plate 91 is located at the connection point of the first extension arm 913 and the second extension arm 914. The first force-bearing part 911 is the side of the first extension arm 913 facing away from the second extension arm 914. Two first hooks 912a are provided at the end of the second extension arm 914 away from the first extension arm 913. The second spring plate 92 includes a third extension arm 923 and a fourth extension arm 924. One end of the third extension arm 923 and the fourth extension arm 924 are connected and arranged substantially perpendicularly. The pivot of the second spring plate 92 is located at the connection point of the third extension arm 923 and the fourth extension arm 924. The second force-bearing part 921 is the side of the third extension arm 923 facing away from the fourth extension arm 924. Two second hooks 922a are provided at the end of the fourth extension arm 924 away from the third extension arm 923.

[0133] Therefore, in this application, since both the first spring plate 91 and the second spring plate 92 are L-shaped and are arranged facing each other, the first extension arm 913 and the third extension arm 923 are intersecting. The force application part 88 is located at the intersection of the first extension arm 913 and the third extension arm 923. Through one force application part 88, the first spring plate 91 and the second spring plate 92 can be driven to rotate around their respective axes simultaneously, thereby storing force for the spring 93, simplifying the structure. Moreover, regardless of whether the main beam 80 rotates clockwise or counterclockwise, the first spring plate 91 and the second spring plate 92 can be driven to rotate around their respective axes simultaneously through a single force application part 88, resulting in a compact structure and better synchronization.

[0134] In some embodiments, the first spring plate 91, the second spring plate 92, and the spring 93 form a space around each other, and the first shaft 20 and the second shaft 70 are located in the space, so as to realize a reasonable spatial arrangement of the rotation shaft of the first spring plate 91, the rotation shaft of the second spring plate 92, the first shaft 20, and the second shaft 70 on the base 10.

[0135] In some embodiments, the pedal control mechanism 100 further includes a damping mechanism 101, one end of which is connected to the base 10 and the other end to the main beam 80, so as to control the rotational damping of the main beam 80.

[0136] In some embodiments, the pedal control mechanism 100 further includes a damping block 102, which is disposed between the lower connecting plate 84 and the limiting connecting plate 30 to adjust the rotational damping of the limiting connecting plate 30 relative to the main beam 80.

[0139] In summary, this application possesses the aforementioned superior characteristics, enabling it to achieve unprecedented performance in use and thus become a highly practical product.
