[0039] Combination Figure 1 An embodiment of this application provides a pedal assembly including a pedal bracket 100, a pedal outer edge 200, a movable pedal 300, and an adjustment mechanism. The pedal bracket 100 is used to connect to the chassis of a vehicle. The pedal outer edge 200 is connected to the pedal bracket 100. The movable pedal 300 is movably mounted on the pedal outer edge 200. The adjustment mechanism connects the pedal outer edge 200 and the movable pedal 300, and is used to drive the movable pedal 300 to move or rotate relative to the pedal outer edge 200 to adjust the posture of the movable pedal 300.

[0040] In some embodiments, the pedal bracket 100 is fixedly connected to the vehicle chassis, serving to support and secure the entire pedal assembly. The connection between the pedal bracket 100 and the chassis can be achieved by bolting or welding, ensuring the stability of the pedal assembly during vehicle operation. The outer edge 200 of the pedal is connected to the pedal bracket 100 and extends along the length of the vehicle. The movable pedal 300 is connected to the outer edge 200 of the pedal via an adjustment mechanism. The adjustment mechanism connects the outer edge 200 of the pedal and the movable pedal 300, allowing the movable pedal 300 to move or rotate under the drive of the adjustment mechanism, thereby changing its posture. The movable pedal 300 may have a streamlined cross-section to optimize water flow guidance, and its surface may be provided with anti-slip protrusions 330 to enhance safety when stepping on it.

[0041] When the vehicle is traveling in water, the movable pedal 300 can be moved or rotated via an adjustment mechanism to adjust its posture, thereby adapting to the direction and force of the water flow and adjusting the vehicle's pitch or roll angle. For example, when the movable pedal 300 is rotated to a certain angle, it can guide the side water flow in a specific direction, reducing vehicle roll; when the movable pedal 300 is moved to adjust the clearance, it can optimize water flow efficiency and enhance posture stability. In the non-adjustable state, the movable pedal 300 remains flat and can be stepped on by personnel to facilitate getting on and off the vehicle.

[0042] The pedal assembly in this embodiment integrates pedal function and posture adjustment function, avoiding the need for additional dedicated devices, saving vehicle space and control resources, while improving driving stability and practicality.

[0043] Combination Figure 2 According to one embodiment of the present invention, the adjustment mechanism includes a horizontal rotation assembly 400, which includes a swing arm 410 and a first rotation drive structure 420. A first end of the swing arm 410 is located at the outer edge 200 of the pedal, and a second end of the swing arm 410 is connected to the movable pedal 300. The first rotation drive structure 420 is located at the outer edge 200 of the pedal and connected to the swing arm 410. The first rotation drive structure 420 is used to drive the swing arm 410 to rotate horizontally about its first end as the center.

[0044] In this embodiment, the swing arm 410 serves as an intermediate component connecting the outer edge 200 of the pedal and the movable pedal 300. Its length is determined according to the adjustment range of the movable pedal 300, ensuring that it can drive the movable pedal 300 to achieve the required horizontal rotation angle during rotation. The swing arm 410 can be made of a material with certain rigidity and toughness to avoid deformation or breakage during power transmission. The first end of the swing arm 410 is located at the outer edge 200 of the pedal, and the second end is fixedly connected to the movable pedal 300, so that the rotation of the swing arm 410 can directly drive the movable pedal 300 to rotate horizontally synchronously.

[0045] The first rotary drive structure 420 is connected to the first end of the swing arm 410, and the resulting driving force acts on the swing arm 410, driving the swing arm 410 to rotate on the horizontal plane around its first end. This, in turn, drives the movable pedal 300 to adjust its horizontal posture via the swing arm 410. For example, when dealing with the impact of side water flow, the first rotary drive structure 420 is activated, transmitting rotational power to the first end of the swing arm 410. The swing arm 410 rotates horizontally around its first end, and through its fixed connection with the movable pedal 300, drives the movable pedal 300 to rotate horizontally, changing its orientation on the horizontal plane. This adjusts the angle of interaction with the water flow, specifically addressing the impact of side water flow, adjusting the vehicle's lateral thrust, and improving vehicle stability.

[0046] In this embodiment, the horizontal rotation component 400 enhances the ability to cope with water flow impact, further improving the vehicle's driving stability in water, and has a simple structure that does not affect the normal pedal function.

[0047] According to one embodiment of the present invention, the first rotary drive structure 420 includes a mounting base, a first rotary shaft, and a first rotary motor. The mounting base is located at the outer edge 200 of the pedal. The first rotary shaft is rotatably connected to the mounting base and fixedly connected to the first end of the swing arm 410. The motor shaft of the first rotary motor is drively connected to the first rotary shaft.

[0048] For example, the mounting base serves as the mounting carrier for the first rotating shaft and the first rotating motor, and is installed on the outer edge 200 of the pedal. The mounting base can be made of a high-strength structure, such as cast steel or thickened steel plate, which can support the weight of the first rotating shaft and the first rotating motor, and withstand the torque generated during rotation, so as to prevent the mounting base from being displaced or damaged due to excessive force, and ensure the stability of the component installation position.

[0049] The first rotating shaft is vertically positioned and connected to the mounting base via rotating components such as bearings, allowing it to rotate freely relative to the mounting base. The first rotating shaft is fixedly connected to the first end of the swing arm 410, such as by keying or welding. The surface of the first rotating shaft undergoes a smoothing treatment, such as chrome plating or nitriding. Chrome plating improves surface finish and enhances wear resistance, while nitriding increases surface hardness, reduces frictional resistance with the mounting base, ensures smooth, uninterrupted rotation of the first rotating shaft, and reduces component wear caused by long-term rotation.

[0050] The motor shaft of the first rotary motor is connected to the first rotating shaft through a transmission structure such as a gear set, for example, through spur gear meshing transmission. The output power of the first rotary motor is designed according to the weight of the swing arm 410 and the movable pedal 300 and the required rotational force, ensuring that the motor can output sufficient power to drive the swing arm 410 to rotate, and can still smoothly drive the swing arm 410 to rotate even when the water flow impact brings additional resistance to the movable pedal 300.

[0051] When the horizontal position of the movable pedal 300 needs to be adjusted, the first rotary motor is powered on, and the motor shaft starts to rotate. The power is transmitted to the first rotating shaft through the transmission structure. The first rotating shaft rotates under the support of the mounting base, and the swing arm 410 rotates around its first end with the first rotating shaft, ultimately causing the movable pedal 300 to change its horizontal orientation to adapt to the impact of the water flow.

[0052] According to one embodiment of the present invention, multiple movable pedals 300 are provided at intervals along the extending direction of the outer edge 200 of the pedal, and multiple horizontal rotating components 400 are provided corresponding to the movable pedals 300.

[0053] Multiple movable pedals 300 are arranged sequentially along the outer edge 200 of the pedal. The horizontal rotation component 400 is configured to correspond one-to-one with the movable pedals 300, that is, each movable pedal 300 is equipped with an independent swing arm 410 and a first rotation drive structure 420, so that each movable pedal 300 can rotate horizontally independently without being affected by the movement state of other movable pedals 300.

[0054] When a vehicle is traveling in water, if a local area on one side of the vehicle is subjected to a strong water flow, the horizontal rotation component 400 of the corresponding movable pedal 300 can be activated only to drive the movable pedal 300 to rotate to a suitable angle to guide the water flow and counteract the local impact. If the entire side of the vehicle is subjected to a uniform water flow, the horizontal rotation components 400 of all movable pedals 300 can be activated simultaneously to rotate all movable pedals 300 at the same angle, forming an overall guiding effect and balancing the overall lateral thrust of the water flow on the vehicle.

[0055] In this embodiment, the horizontal rotation component 400 corresponds one-to-one with the movable pedal 300, allowing each movable pedal 300 to be adjusted independently. This enhances the flexibility and specificity of posture adjustment, enabling precise adjustment of the corresponding movable pedal 300 based on the specific location and intensity of the water flow impact. This avoids the waste of power and resources caused by overall adjustment, improving adjustment efficiency. For example, adjusting only the left front movable pedal 300, which is subject to impact, can save power consumption. When multiple movable pedals 300 rotate collaboratively, a wider flow guidance range can be formed, covering a larger area on the side of the vehicle body, enhancing the guiding effect on the water flow. Furthermore, the simultaneous flow guidance of multiple movable pedals 300 can balance the water flow impact force at different locations on the vehicle body, preventing excessive local force that could cause the vehicle body to tilt. In addition, if the horizontal rotation component 400 of a single movable pedal 300 fails, the other movable pedals 300 can still operate normally, preventing the horizontal adjustment function of the entire pedal assembly from failing, thus improving the fault tolerance and reliability of the pedal assembly.

[0056] Combination Figure 2 and Figure 3 According to one embodiment of the present invention, the adjustment mechanism further includes a movable drive assembly 500. Multiple movable drive assemblies 500 are provided corresponding to the horizontal rotation assemblies 400. The movable drive assembly 500 is connected to the mounting base of the corresponding horizontal rotation assembly 400. The movable drive assembly 500 is used to drive the mounting base to move along the extension direction of the outer edge 200 of the pedal to adjust the distance between adjacent movable pedals 300.

[0057] The number of movable drive assemblies 500 is the same as that of horizontal rotation assemblies 400, ensuring that each mounting base corresponding to a horizontal rotation assembly 400 receives independent driving force. The movable drive assembly 500 is installed along the extending direction of the outer edge 200 of the pedal, for example, by bolting it to the inner track of the outer edge 200 of the pedal, ensuring that the direction of movement of its driving mounting base is consistent with the extending direction of the outer edge 200 of the pedal, preventing the mounting base from deviating from the preset track during movement. The mounting base is adapted to the installation requirements of the horizontal rotation assembly 400; for example, bolt holes are provided on the top of the mounting base for fixing the first rotary motor and bearing housing, ensuring that the horizontal rotation assembly 400 can be stably installed on the mounting base and move synchronously with the mounting base.

[0058] Since the horizontal rotating component 400 is mounted on the mounting base, and the movable pedal 300 is connected to the horizontal rotating component 400, the sliding of the mounting base will cause the horizontal rotating component 400 and the movable pedal 300 to move synchronously, thereby changing the distance between adjacent movable pedals 300.

[0059] When it is necessary to reduce the distance between adjacent movable pedals 300 to form a flat tread surface 310, the movable drive assembly 500 drives the mounting base to slide closer to the adjacent mounting base, causing the movable pedals 300 to move synchronously and reduce the distance; when it is necessary to increase the distance between adjacent movable pedals 300 to optimize the water flow channel, the movable drive assembly 500 drives the mounting base to slide away from the adjacent mounting base, causing the movable pedals 300 to move synchronously and increase the distance.

[0060] In addition, the moving drive assembly 500 drives the mounting base to slide away from the adjacent mounting base, causing the movable pedal 300 to move synchronously, increasing the distance between the movable pedals 300, and also providing sufficient space for the horizontal rotation assembly 400 to drive the movable pedal 300 to rotate horizontally.

[0061] According to one embodiment of the present invention, the moving drive assembly includes a second drive motor 510, a slider 520, a crank 530, and a connecting rod 540. The second drive motor 510 is fixed to the outer edge 200 of the pedal. The slider 520 is slidably connected to the outer edge 200 of the pedal along the extending direction of the outer edge 200 and is fixedly connected to a mounting base. One end of the crank 530 is fixedly connected to the motor shaft of the second drive motor 510. One end of the connecting rod 540 is rotatably connected to the end of the crank 530 opposite to the motor shaft, and the other end of the connecting rod 540 is rotatably connected to the slider 520.

[0062] The second drive motor 510 is fixed to the outer edge 200 of the pedal by a motor bracket bolt. Its output power is designed according to the total weight of the sliding member 520, the horizontal rotating component 400 and the movable pedal 300 to ensure that the motor can output enough power to drive the sliding member 520 to move. Even if it is subjected to certain frictional resistance during the sliding process, it can still drive the sliding member 520 smoothly.

[0063] The shape of the slider 520 is adapted to the sliding track of the outer edge 200 of the pedal. For example, if the sliding track is a T-slot, the bottom of the slider 520 is designed as a corresponding T-block, ensuring that the slider 520 can only slide along the extension direction of the outer edge 200 of the pedal and avoid deviation. Optionally, the surface of the slider 520 is made of wear-resistant material or undergoes wear-resistant treatment, such as using nylon or hard anodizing. Nylon itself has good wear resistance, and hard anodizing can improve the surface hardness of the metal, reduce wear between long-term sliding and the track, and extend the service life of the slider 520.

[0064] The slider 520 and the mounting base are separately formed and fixedly connected by means such as snap-fit, bonding or welding, or the slider 520 and the mounting base are integrally formed. When the slider 520 slides, it can drive the mounting base to slide synchronously.

[0065] The length of crank 530 is determined according to the required travel of slider 520, ensuring that when crank 530 rotates one revolution, it can drive slider 520 to move a preset distance through connecting rod 540, so as to achieve precise adjustment of the distance between adjacent active pedals 300.

[0066] The connecting rod 540 is rotatably connected at both ends to the crank 530 and the slider 520, respectively. This connection, via a pin, allows the rotational motion of the crank 530 to be smoothly converted into the linear motion of the slider 520. The connecting rod 540 can be made of a material with a certain degree of toughness, such as spring steel or high-strength resin. Spring steel has good elasticity and can withstand repeated bending, while high-strength resin is lightweight and corrosion-resistant, preventing breakage due to excessive force during power transmission.

[0067] When the second drive motor 510 starts, the motor shaft drives the crank 530 to move in a circular motion around the motor shaft. The crank 530 pulls or pushes the slider 520 through the connecting rod 540, so that the slider 520 moves in a straight line along the sliding track of the outer edge 200 of the pedal. This drives the mounting base and the horizontal rotating component 400 on the mounting base and the movable pedal 300 to move synchronously, thereby adjusting the distance between adjacent movable pedals 300.

[0068] In this embodiment, the mobile drive assembly achieves efficient conversion of rotational power to linear power through the coordinated operation of its components, ensuring precise and smooth adjustment of the movable pedal 300 spacing and further optimizing the pedal assembly's functionality. Furthermore, the reciprocating movement of the mounting base can be achieved through the co-rotation of the second drive motor 510, effectively reducing structural complexity and control difficulty.

[0069] According to one embodiment of the present invention, the outer edge 200 of the pedal is provided with a mounting cavity, and the motion drive assembly 500 and the mounting seat are located in the mounting cavity.

[0070] The mounting cavity is a hollow space created inside the outer edge 200 of the pedal. Its shape and size are determined according to the volume and shape of the moving drive assembly 500 and the mounting base, ensuring that the moving drive assembly 500 and the mounting base can be completely accommodated within the mounting cavity. At the same time, sufficient space is reserved inside the mounting cavity to prevent the mounting base from colliding or interfering with the inner wall of the mounting cavity when the moving drive assembly 500 drives the mounting base to move. A lateral opening is formed on one side of the mounting cavity, through which the swing arm 410 passes, thereby providing room for the swing arm 410 to swing and move.

[0071] Optionally, the outer edge 200 of the pedal can be made of high-strength materials, such as stainless steel or high-strength engineering plastics. Stainless steel has good corrosion resistance and strength, making it suitable for aquatic environments, while high-strength engineering plastics are lightweight, easy to mold, and can withstand external impact forces, protecting the internal moving drive components 500 and mounting base from damage. Simultaneously, the outer surface is treated with anti-corrosion measures, such as spraying anti-rust paint or surface passivation, to prevent corrosive substances in the water flow from corroding the outer wall of the pedal outer edge 200 and internal components when the vehicle is traveling in water.

[0072] By placing the mobile drive assembly 500 and the mounting base inside the mounting cavity, on the one hand, the outer wall of the pedal outer edge 200 can shield and protect the mobile drive assembly 500 and the mounting base, ensuring long-term stable operation of the mobile drive assembly 500 and the mounting base, reducing maintenance needs, and improving the reliability of the pedal assembly; on the other hand, it can prevent the mobile drive assembly 500 and the mounting base from affecting the pedal assembly's entry and exit functions; and furthermore, it helps to reduce space occupation and reduce wind resistance during vehicle operation.

[0073] Combination Figure 4 According to one embodiment of the present invention, the adjustment mechanism further includes a second rotary drive structure 600, which is used to drive the movable pedal 300 to rotate vertically.

[0074] The second rotary drive structure 600 is used to provide vertical rotational power for the movable pedal 300. The vertical rotation of the movable pedal 300 refers to its rotation around an axis parallel to the ground. The rotation angle is determined according to the water flow adjustment requirements, ensuring that the angle between the guide surface 320 of the movable pedal 300 and the water flow can be changed by rotation, thereby guiding the direction of the water flow and balancing the impact of the water flow on the vehicle body.

[0075] For example, when a vehicle is traveling in water and is impacted by a frontal or oblique water flow, the second rotary drive structure 600 is activated, outputting rotational power and transmitting it to the movable pedal 300. This drives the movable pedal 300 to rotate around the vertical axis, changing the orientation of the guide surface 320. By adjusting the rotation angle, the guide surface 320 forms a suitable angle with the water flow. When the water flow impacts the guide surface 320, it generates a reverse force. This reverse force can offset part of the impact force of the water flow on the vehicle body, thereby adjusting the vehicle's pitch angle and maintaining vehicle stability.

[0076] The second rotary drive structure 600 enables the vertical rotation of the movable pedal 300, and works in conjunction with the horizontal rotation component 400 to form a multi-directional adjustment capability. This allows the movable pedal 300 to flexibly adjust its posture according to the direction of water flow impact, such as lateral, forward, or oblique, covering a wider range of water flow conditions, improving its ability to cope with water flow impacts from different directions, and enhancing the vehicle's stability when driving in water.

[0077] According to one embodiment of the present invention, the adjustment mechanism includes a horizontal rotation component 400, the horizontal rotation component 400 includes a swing arm 410, the movable pedal 300 is rotatably connected to the swing arm 410 via a second rotation shaft, the movable pedal 300 has a pedal cavity 340, the second rotation drive structure 600 includes a second rotary motor, the second rotary motor is fixed in the pedal cavity 340, and the motor shaft of the second rotary motor is connected to the second rotation shaft.

[0078] In some embodiments, the second rotating shaft serves as a support component for the vertical rotation of the movable pedal 300. The second rotating shaft may be made of high-strength materials, such as No. 45 steel or alloy steel, with good comprehensive mechanical properties, higher strength and wear resistance, ensuring that it can withstand the weight of the movable pedal 300 and the force during vertical rotation.

[0079] The pedal cavity 340 is a hollow space inside the movable pedal 300, which can accommodate the second rotary motor and reduce the weight and production cost of the pedal cavity 340 without affecting the structural strength and pedaling function of the movable pedal 300.

[0080] The movable pedal 300 is rotatably connected to the swing arm 410 via the second rotating shaft. If the second rotating shaft is fixed perpendicularly to the swing arm 410 and is rotatably engaged with the bushing of the movable pedal 300, the movable pedal 300 can rotate freely vertically around the second rotating shaft.

[0081] The second rotary motor is fixedly installed in the pedal cavity 340 of the movable pedal 300, such as by fixing it with motor bracket bolts. The motor shaft of the second rotary motor is fixedly connected to one end of the second rotary shaft located in the pedal cavity 340, or by connecting it with a coupling to form a power transmission link.

[0082] When the vertical orientation of the movable pedal 300 needs to be adjusted, the second rotary motor is powered on, and its motor shaft begins to rotate. Since the motor shaft of the second rotary motor is fixedly connected to the second rotating shaft, the motor shaft of the second rotating shaft does not rotate, while the stator rotates in the opposite direction, causing the movable pedal 300 to rotate vertically around the second rotating shaft. If the horizontal orientation of the movable pedal 300 also needs to be adjusted, the horizontal rotation component 400 can drive the swing arm 410 to rotate the movable pedal 300 horizontally. The two rotation actions can be performed individually or simultaneously, adjusting the movable pedal 300 to the optimal flow guiding orientation according to the water flow impact.

[0083] This embodiment can achieve a high degree of integration between the second rotary drive structure 600 and the movable pedal 300, which not only ensures the stable realization of the vertical rotation function, but also optimizes the structural layout of the movable pedal 300 and improves the practicality and reliability of the pedal assembly.

[0084] Combination Figure 5 According to one embodiment of the present invention, the pedal bracket 100 includes a fixed base 110 and a telescopic assembly 120. The fixed base 110 is fixedly connected to the chassis of the vehicle. The telescopic assembly 120 connects the fixed base 110 and the outer edge of the pedal 200, and the telescopic assembly 120 is used to drive the outer edge of the pedal 200 to move between a first position located below the chassis of the vehicle and a second position located outside the chassis of the vehicle.

[0085] In some embodiments, the mounting base 110 serves as a connecting component between the pedal bracket 100 and the vehicle chassis. Its structure is determined by the installation position and shape of the chassis. For example, if the side of the chassis is planar, the mounting base 110 is designed as a flat plate; if the side of the chassis has raised reinforcing ribs, the mounting base 110 is designed as a grooved structure to ensure a tight fit with the chassis. The mounting base 110 can be made of high-strength materials, such as Q235 steel or aluminum alloy, to withstand the weight of the entire pedal assembly and the pedaling force and water flow impact transmitted during use, preventing deformation or damage due to excessive force. The mounting base 110 can be fixed to the vehicle chassis by means such as bolts or welding.

[0086] The telescopic assembly 120 can use a hydraulic or electric telescopic structure as its power source. When the telescopic assembly 120 extends or retracts, it can drive the outer edge of the pedal 200 to switch accurately between two positions. Specifically, when the telescopic assembly 120 retracts, its length shortens, pulling the outer edge of the pedal 200 towards the chassis, eventually bringing the outer edge of the pedal 200 to the first position, where it is stored under the chassis. When the telescopic assembly 120 extends, its length length lengthens, pushing the outer edge of the pedal 200 away from the chassis, eventually bringing the outer edge of the pedal 200 to the second position, located outside the chassis.

[0087] When the vehicle does not require the use of the pedal function and posture adjustment, the telescopic component 120 retracts, pulling the outer edge 200 of the pedal to a first position under the chassis, for example, below the door trim panel near the inner side of the vehicle. In this position, the outer edge 200 of the pedal does not protrude from the side of the vehicle, reducing air resistance during vehicle movement and preventing impact from external obstacles. When passengers need to get in and out of the vehicle, or when the vehicle needs posture adjustment in water, the telescopic component 120 extends, pushing the outer edge 200 of the pedal to a second position outside the chassis. At this time, the movable pedal 300 can be adjusted to a flat position for passengers to step on, or its posture can be adjusted to guide water flow and balance the impact of the water flow on the vehicle body. This achieves the telescopic storage of the outer edge 200 of the pedal, optimizing vehicle driving performance while ensuring the effective implementation of the pedal function and posture adjustment function, thus improving the overall performance of the vehicle.

[0088] For example, the telescopic assembly 120 includes a first connecting arm 121, a second connecting arm 122, a support arm 123, and a power component (not shown in the figure). The first connecting arm 121 and the second connecting arm 122 are arranged in parallel. One end of the first connecting arm 121 and the second connecting arm 122 in the same direction is rotatably connected to the fixed base 110, and the other end in the same direction is rotatably connected to the support arm 123. The support arm 123 is fixedly connected to the outer edge 200 of the pedal. The power component includes a rotary motor or a telescopic motor, etc. The power component is disposed on the fixed base 110 and its driving end is connected to the first connecting arm 121 and / or the second connecting arm 122, thereby driving the first connecting arm 121 and the second connecting arm 122 to rotate vertically through rotation or telescopic movement, and then driving the outer edge 200 of the pedal to move between the first position and the second position through the support arm 123.

[0089] Optionally, the first connecting arm 121, the second connecting arm 122, and the support arm 123 in the telescopic assembly 120 are each provided in two at intervals along the length of the vehicle to increase the stability of the telescopic assembly 120 during operation.

[0090] Optionally, the telescopic assembly 120 is provided in two or more at intervals along the length of the vehicle, thereby achieving multi-point support for the outer edge 200 of the pedal.

[0091] Combination Figure 1 According to one embodiment of the present invention, the pedal assembly further includes at least one fixed pedal 700. The fixed pedal 700 is fixedly connected to the outer edge 200 of the pedal.

[0092] In this embodiment, the fixed pedal 700 and the movable pedal 300 are used together. The number of fixed pedals 700 is determined according to the vehicle size and pedaling requirements. For example, three fixed pedals 700 can be set, respectively arranged at both ends and the middle of the outer edge 200 of the pedal. The fixed pedal 700 and the outer edge 200 of the pedal are firmly connected by welding or bolts to ensure that the fixed pedal 700 will not move or rotate. The surface of the fixed pedal 700 is provided with an anti-slip structure, such as raised texture and anti-slip rubber pad. The raised texture can increase the friction with the sole of the shoe, and the anti-slip rubber pad can maintain a good anti-slip effect in wet environments to enhance the safety of pedaling and prevent people from slipping in wet environments.

[0093] When the vehicle is being used for normal boarding and alighting and the movable pedal 300 is in a flat state, the fixed pedal 700 and the movable pedal 300 together form a continuous and flat stepping surface 310, on which personnel can step steadily without their feet getting stuck due to excessive pedal gaps. When the movable pedal 300 needs to be adjusted in spacing or rotated to cope with the impact of water flow, the fixed pedal 700 remains fixed, and personnel can still step on the fixed pedal 700 to board and alight, avoiding interruption of the boarding and alighting function due to the adjustment of the movable pedal 300.

[0094] Optionally, the fixed pedal 700 is also fixedly connected to the pedal bracket 100 to enhance the structural stability of the entire pedal assembly.

[0095] According to one embodiment of the present invention, the movable pedal 300 has a stepping surface 310 and a guide surface 320 arranged opposite to each other. The stepping surface 310 is provided with anti-slip protrusions 330, and the guide surface 320 is curved in a direction away from the stepping surface 310.

[0096] The step surface 310 is the surface of the movable pedal 300 for people to step on. Optionally, the step surface 310 is an arc-shaped surface that curves towards the guide surface 320 in the middle, which can make people's feet more comfortable when stepping on it.

[0097] The guide surface 320 is the surface of the movable pedal 300 used to guide the water flow. It is curved in the direction away from the stepping surface 310 to form an arc structure. The curvature of the arc is designed according to the principle of hydrodynamics. For example, the radius of curvature is 10-15 cm to ensure that the water flow can flow smoothly along the arc surface when it impacts the guide surface 320, reduce the impact resistance of the water flow on the movable pedal 300, and at the same time generate a reverse force in a preset direction.

[0098] Anti-slip protrusions 330 are evenly distributed on the foot surface 310, effectively increasing the friction between the foot surface 310 and the sole. The anti-slip protrusions 330 are integrally molded with the foot surface 310 or fixedly connected to the foot surface 310, such as by integral injection molding or by adhesive bonding, ensuring that they will not easily fall off.

[0099] When the movable pedal 300 is used for getting on and off the vehicle, the step surface 310 faces upwards, and the anti-slip protrusions 330 contact the sole of the shoe to increase friction and prevent slipping. When the movable pedal 300 is used for posture adjustment, the guide surface 320 faces the direction of water flow. After the water flow impacts the guide surface 320, it flows along the arc-shaped surface, generating a reverse force on the guide surface 320 during the flow. This force is transmitted to the vehicle body, balancing the impact of the water flow on the vehicle body and adjusting the vehicle's posture. For example, when impacted by water flow from the front, the guide surface 320 guides the water flow to both sides, generating a reverse force to counteract the forward impact of the water flow on the vehicle body, preventing excessive pitching of the vehicle body, thus keeping the pitch angle within a safe range.

[0100] Optionally, the front portion of the movable pedal 300 is thicker than the rear portion. The front portion of the movable pedal 300 refers to the side of the pedal assembly facing away from the water flow direction when the assembly is in flow-guiding mode, while the rear portion refers to the side of the pedal assembly facing the water flow direction when the assembly is in flow-guiding mode. This thickness difference ensures the front portion is relatively thicker while meeting the requirements for stepping and load-bearing capacity, while the rear portion is relatively thinner while meeting basic structural strength requirements.

[0101] The front part of the movable pedal 300 is thicker, allowing for more internal space to accommodate adjustment components such as the second rotary motor and the second rotary shaft. When these components are installed inside the front part, there will be no cramped installation or movement interference due to insufficient space. At the same time, as the main area that directly bears the impact of water flow in the direction of vehicle movement, the thicker structure of the front part enhances its resistance to bending and fracture, preventing deformation under the impact of water flow.

[0102] The rear part of the active pedal 300 is thinner, which reduces its overall weight and avoids adding extra load to the adjustment mechanisms such as the moving drive component 500 and the horizontal rotation component 400. On the other hand, its thinner structure has a smaller obstruction area for water flow, which reduces the resistance when water flows through it.

[0103] When the vehicle travels in the direction of travel in water, the water flow first contacts the front part of the movable pedal 300. Due to its greater thickness and stronger structure, the front part can directly resist the frontal impact of the water flow. At the same time, the internal adjustment components work stably within the ample space, driving the movable pedal 300 to rotate vertically or horizontally, adjusting the angle between the guide surface 320 and the water flow. After passing through the front part, the water flows to the rear part. The thinner rear part allows the water flow to flow more smoothly along the guide surface 320, reducing the formation of turbulence on the pedal surface and avoiding additional disturbance forces caused by turbulence that affect the vehicle's posture. When the movable pedal 300 is in the pedaling position, the person's foot usually lands on the front part of the pedal, and the thicker front part can more stably bear the pedaling force.

[0104] The present invention also provides a vehicle, including a chassis and a pedal assembly according to the above embodiments. The pedal bracket 100 of the pedal assembly is connected to the chassis. Pedal assemblies are respectively provided on both sides of the chassis, and the pedal assemblies on both sides of the chassis are symmetrically arranged.

[0105] In some embodiments, the installation positions of the pedal assemblies are symmetrically arranged on both sides of the vehicle chassis. The distance between the installation positions on both sides and the center line of the chassis is equal, and the height is completely consistent. This ensures that the pedal assemblies on both sides are in a symmetrical state after installation, and avoids uneven forces generated when adjusting the pedal assemblies on both sides due to asymmetrical installation positions, which would affect the vehicle body balance.

[0106] Alternatively, the pedal assemblies on both sides are structurally identical but face opposite directions to meet the needs of getting on and off the vehicle from both sides and to guide traffic flow.

[0107] The adjustment mechanisms on both sides can be controlled independently or synchronously. For example, when one side of the vehicle body is impacted by a strong water flow, the adjustment mechanism of the pedal assembly on that side can be activated independently to adjust the posture of the movable pedal 300 to balance the impact. For instance, if the left side is impacted by a strong water flow, the adjustment mechanism of the left pedal assembly drives the movable pedal 300 to adjust its posture, guiding the water flow to generate a force to the right. This force balances the impact force of the water flow on the left side, preventing the vehicle body from tilting to the right. When both sides of the vehicle body are impacted by a uniform water flow, the adjustment mechanisms of both pedal assemblies can be activated synchronously to create a symmetrical guiding effect on the movable pedals 300, preventing the vehicle body from becoming unbalanced. For instance, if the vehicle is impacted by a uniform water flow in the front-to-back direction, the adjustment mechanisms of both pedal assemblies synchronously drive the movable pedal 300 to rotate, so that the guide surfaces 320 on both sides form a symmetrical guide angle, guiding the water flow to both sides and generating a reverse force to counteract the front-to-back impact of the water flow on the vehicle body, preventing the vehicle body from pitching excessively.

[0108] In this embodiment, the two-side pedal assemblies work together to cover water flow impact scenarios on both sides of the vehicle body, enhancing the vehicle's adaptability to different water flow environments. For example, under conditions such as unilateral impact, uniform impact on both sides, and oblique impact, effective attitude adjustment can be achieved by flexibly adjusting the attitude of the two-side movable pedals by 300 degrees. Therefore, the vehicle's attitude stability while driving in water is significantly improved, its adaptability to complex water flow environments is enhanced, and the overall performance of the vehicle is further optimized.

[0109] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0110] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
