[0008] A ground-supporting mechanism includes a second driving member, a movable support leg, and a rolling wheel. The movable support leg is movably connected to the bottom end of a fixed support leg. The second driving member is connected to one end of the movable support leg and is used to drive the movable support leg to move. The bottom end of the movable support leg is connected to the rolling wheel, and the other end of the driven rod is connected to the bottom of the fixed support leg.
[0009] The pedal body is connected to the fixed support leg.
[0010] Preferably, a limiting block is provided at the top of the fixed support leg;
[0011] The telescopic pedal device also includes a detection module, which includes a first limit sensor and a second limit sensor. The first limit sensor is electrically connected to the rolling wheel and is used to detect whether the rolling wheel is in contact with the ground. The second limit sensor is electrically connected to the limiting block and is used to detect whether the limiting block is in contact with the second side of the operating platform in the vehicle width direction.

[0017] Preferably, the surface of the pedal body is provided with anti-slip texture.
[0018] Secondly, this application provides a vehicle including the telescopic pedal device provided in the first aspect of this application.
[0019] Compared with the prior art, the telescopic pedal device and vehicle provided in this application achieve at least the following beneficial effects:
[0020] In this application, the telescopic pedal device includes an operating platform, a platform support, an extension mechanism, a ground support mechanism, and a pedal body. The first side of the operating platform is connected to the vehicle, and the second side is connected to the pedal body via a linkage assembly. The operating platform establishes a connection structure between the vehicle and the pedal body, enabling their interaction. The platform support provides reliable support for the operating platform and provides a mounting carrier for the extension mechanism. The extension mechanism includes a first driving member and a linkage assembly. The linkage assembly includes a driving rod, a driven rod, a support rod, and a fixed support leg. The first driving member drives the extension mechanism to move. Specifically, the first driving member drives the driving rod to rotate, which in turn drives the driven rod to move. The moving driven rod causes the bottom of the fixed support leg to move towards or away from the operating platform. The fixed support leg also drives one end of the support rod to move. Simultaneously, because the other end of the support rod is connected to the platform support, the support rod also exerts a force on the fixed support leg, causing the fixed support leg to rotate. The movement of the fixed outriggers allows the top of the fixed outriggers to move towards or away from the operating platform. In the vehicle's width direction, the bottom of the fixed outrigger moves in the opposite direction to its top. When the top of the fixed outrigger moves towards the operating platform until it touches the platform or the distance between them is small, the fixed outrigger rotates to a tilted position and extends outward from its position near the platform. At this point, the telescopic pedal device is in its extended state, creating a step difference between the ground, the pedal body, and the operating platform, making passenger entry and exit more natural and effortless, improving travel comfort and optimizing the overall riding experience. Conversely, when the top of the fixed outrigger moves away from the operating platform until it is essentially perpendicular to the ground and the distance between the support rod and the platform bracket is minimized, the pedal body is closest to the operating platform, occupying minimal space and reducing the probability of collisions between the telescopic pedal device and people or objects around the vehicle during driving, while also enhancing aesthetics. This telescopic pedal device, through its extension mechanism and over-support mechanism, can switch the position and state of the pedal body, and its structure is simple and easy to operate.
[0021] Of course, any product implementing this application need not specifically need to achieve all of the technical effects described above at the same time.

[0038] Please refer to Figures 1 to 5This application provides a telescopic pedal device, including an operating platform 100, a platform support 200, an extension mechanism 300, a ground support mechanism 400, and a pedal body 500. The operating platform 100 is connected to the vehicle frame 101 on a first side in the vehicle width direction D1; the platform support 200 is connected to the operating platform 100 on a second side in the vehicle width direction D1; the extension mechanism 300 includes a first drive member 310 and a linkage assembly 320. The first drive member 310 is mounted on the platform support 200, and the linkage assembly 320 includes a driving rod 321, a driven rod 322, a support rod 323, and a fixed support leg 324. The first drive member 310 is connected to one end of the driving rod 321 to drive the driving rod 321 to rotate; the other end of the driving rod 321 is connected to the driven rod 322. One end of the support rod 323 is rotatably connected to the platform support 200, and the other end of the support rod 323 is rotatably connected to the middle of the fixed support leg 324. The ground support mechanism 400 includes a second drive member, a movable support leg 410, and a rolling wheel 420. The movable support leg 410 is rotatably connected to the bottom end of the fixed support leg 324. The second drive member is connected to one end of the movable support leg 410 to drive the movable support leg 410 to move. The bottom end of the movable support leg 410 is connected to the rolling wheel 420, and the other end of the driven rod 322 is connected to the bottom of the fixed support leg 324. The pedal body 500 is connected to the fixed support leg 324.
[0039] It should be understood that the movable support leg 410 is movably connected to the bottom end of the fixed support leg 324, meaning that the movable support leg 410 and the bottom end of the fixed support leg 324 can be slidably connected. The movable support leg 410 can extend beyond the bottom end of the fixed support leg 324, and the movable support leg 410 is equivalent to an extension of the fixed support leg 32 in its extension direction. The movable support leg 410 can extend a certain distance beyond the bottom end of the fixed support leg 324 to make contact with the ground, and it can also retract a certain distance from the bottom end of the fixed support leg 324 to detach from the ground. Alternatively, the movable support leg 410 and the bottom end of the fixed support leg 324 can be rotatably connected, allowing the movable support leg 410 to rotate at the bottom end of the fixed support leg 324. During rotation, as the angle between the movable support leg 410 and the fixed support leg 324 changes, the movable support leg 410 can rotate to make contact with the ground, or it can rotate in the opposite direction to detach from the ground.
[0040] The following is the usage process of the telescopic pedal device provided in this embodiment:
[0041] The telescopic pedal device is in the retracted state when not in use (see...). Figure 1 and Figure 2 This saves space. When the telescopic pedal device needs to switch from the retracted state to the extended state, firstly, the second drive unit is activated. The second drive unit drives the movable support leg 410 to move. The movable support leg 410 moves relative to the fixed support leg 324 until the roller 420 connected to one end of the movable support leg 410 touches the ground (see...). Figure 3 The second drive unit stops driving the movable outrigger 410; then, the first drive unit 310 is activated, which drives the active rod 321 to rotate. The active rod 321 drives the driven rod 322 to move, and the driven rod 322 drives the bottom end of the fixed outrigger 324 to move away from the platform support 200 along the vehicle width direction D1. The rolling wheel 420 follows the movement of the fixed outrigger 324 and rolls on the ground. Because the two ends of the support rod 323 are rotatably connected to the platform support 200 and the fixed outrigger 324 respectively, the bottom end of the fixed outrigger 324 moves away from the platform support 200 along the vehicle width direction D1. During movement, the strut 323 restricts the movement of the middle part of the fixed support leg 324. The strut 323 restrains the fixed support leg 324, causing it to rotate. This rotation is centered on the axis of rotation connecting the strut 323 and the fixed support leg 324 (i.e., the middle part of the fixed support leg 324). The top of the fixed support leg 324 moves towards the platform support 200 until the gap between the top of the fixed support leg 324 and the operating platform 100 on the second side of the vehicle width direction D1 decreases to a certain distance (or even comes into contact with each other). At this point, the telescopic pedal device completes the switch from the retracted state to the extended state (see...). Figure 4 and Figure 5 ).
[0042] When the telescopic pedal device is in the extended state (see...) Figure 4 and Figure 5 Passengers can get on and off the vehicle by stepping on the foot pedal body 500. When the retractable pedal device needs to switch from the retracted state to the extended state, firstly, the first drive member 310 is activated. The first drive member 310 rotates in the opposite direction and drives the active rod 321 to rotate. The active rod 321 drives the driven rod 322 to move. Then, the driven rod 322 drives the bottom end of the fixed support leg 324 to move along the vehicle width direction D1 towards the platform support 200. The rolling wheel 420 follows the movement of the fixed support leg 324 and rolls on the ground. In this configuration, because the two ends of the strut 323 are rotatably connected to the platform support 200 and the fixed support leg 324 respectively, the fixed support leg 324 rotates under the support of the strut 323. The top of the fixed support leg 324 moves away from the platform support 200. Thus, the driven rod 322 and the strut 323 continue to drive the fixed support leg 324 to move. While rotating, the fixed support leg 324 moves towards the platform support 200 in the vehicle width direction D1 until it is substantially perpendicular to the ground and the distance between the strut 323 and the platform support 200 is minimized (see...). Figure 3 Then, the second drive unit is activated, which drives the movable support leg 410 to move relative to the fixed support leg 324 until the roller 420 connected to one end of the movable support leg 410 rises and leaves the ground (see...). Figure 1 and Figure 2 The telescopic pedal device completes the switching from the extended state to the retracted state.
[0043] In this embodiment, the telescopic pedal device includes an operating platform 100, a platform support 200, an extension mechanism 300, a ground support mechanism 400, and a pedal body 500. The first side of the operating platform 100 is connected to the vehicle, and the second side of the operating platform 100 is connected to the pedal body 500 via a linkage group 320. The operating platform 100 establishes a connection structure between the vehicle and the pedal body 500, enabling their interaction. The platform support 200 provides reliable support for the operating platform 100 and provides a mounting carrier for the extension mechanism 300. The extension mechanism 300 includes a first driving member 310 and a linkage group 320. 20. The linkage assembly 320 includes a driving rod 321, a driven rod 322, a support rod 323, and a fixed support leg 324. The first driving member 310 can drive the extension mechanism 300 to move. Specifically, the first driving member 310 can drive the driving rod 321 to rotate. The rotating driving rod 321 can drive the driven rod 322 to move. The moving driven rod 322 can drive the bottom of the fixed support leg 324 to move towards or away from the operating platform 100. The fixed support leg 324 can also drive one end of the support rod 323 to move. At the same time, because the other end of the support rod 323 is connected to the platform support 200, the support rod 323... This also exerts a force on the fixed support leg 324, causing it to rotate. This allows the top end of the fixed support leg 324 to move away from or towards the operating platform 100. In the vehicle width direction D1, the bottom end of the fixed support leg 324 moves in the opposite direction to the top end. The top end of the fixed support leg 324 moves towards the operating platform 100 until it comes into contact with or is close to the operating platform 100. At this point, the fixed support leg 324 rotates to an inclined position, extending outwards from its position near the operating platform 100. When the retractable pedal device is in the extended state, a certain step difference is created between the ground, the pedal body 500, and the operating platform 100, making passenger boarding and alighting more natural and effortless, improving travel comfort, and optimizing the overall riding experience. The top of the fixed support leg 324 moves away from the operating platform 100 until the fixed support leg 324 is basically perpendicular to the ground, and the distance between the support rod 323 and the platform support 200 is minimized. At this point, the pedal body 500 is closest to the operating platform 500, occupying little space and reducing the probability of collisions between the retractable pedal device and people or objects around the vehicle during driving, while also enhancing aesthetics. This retractable pedal device can switch the position and state of the pedal body 500 through the extension mechanism 300 and the over-support mechanism 400, and its structure is simple and easy to operate.
[0044] In addition, the ground support mechanism 400 includes a second drive member, a movable support leg 410, and a roller 420. The second drive member can drive the movable support leg 410 to move relative to the fixed support leg 324, so that the roller 420 at the bottom of the movable support leg 410 can switch between touching the ground and leaving the ground. When the roller 420 touches the ground, the roller 420 and the movable support leg 410 can jointly provide support for the fixed support leg 324. When the roller 420 leaves the ground, it can prevent the roller 420 from rubbing against the ground (or ground objects) during vehicle movement.
[0045] It should be noted that when the telescopic pedal device switches from the retracted state to the extended state, the ground support mechanism 400 needs to be executed before the extension mechanism 300, and when the telescopic pedal device switches from the retracted state to the extended state, the extension mechanism 300 needs to be executed before the ground support mechanism 400. In this way, during the movement of the fixed support leg 324, the movable support leg 410 can form rolling friction with the ground, which can reduce the friction between the movable support leg 410 and the ground.
[0046] See Figures 1 to 5 In some embodiments, a limiting block 3241 is provided at the end of the fixed outrigger 324 away from the movable outrigger 410; the telescopic pedal device also includes a detection module, which includes a first limiting sensor and a second limiting sensor that are electrically connected to each other. The first limiting sensor is electrically connected to the rolling wheel 420 and is used to detect whether the rolling wheel 420 is in contact with the ground; the second limiting sensor is electrically connected to the limiting block 3241 and is used to detect whether the limiting block is in contact with the second side of the operating platform 100 in the vehicle width direction D1; the first limiting sensor is electrically connected to both the first driving member 310 and the second driving member, and the second limiting sensor is electrically connected to both the first driving member 310 and the second driving member.
[0047] In this embodiment, the telescopic pedal device further includes a detection module, which includes a first limit sensor and a second limit sensor electrically connected to each other. The first limit sensor and the second limit sensor can send corresponding signals to the first drive member 310 and the second drive member in a timely manner, so that the first drive member 310 and the second drive member can react in a timely manner. Specifically, when the telescopic pedal device switches from the retracted state to the extended state, the second drive member drives the movable support leg 410 to move. When the first limit sensor detects that the rolling wheel 420 is in contact with the ground, the first limit sensor can send a signal to the second drive member. After receiving the signal, the second drive member can stop driving the movable support leg 410 to continue moving. In addition, the first limit sensor can also send a signal to the first drive member 310. After receiving the signal, the first drive member 310 can start driving the active rod 321 to rotate until the second limit sensor detects that the limit block 3241 is in contact with the second side of the operating platform 100 in the vehicle width direction D1, indicating that the action of switching the telescopic pedal device to the extended state is completed. When the telescopic pedal device switches from the extended state to the retracted state, the second limit sensor sends a signal to the first drive member 310. Upon receiving the signal, the first drive member drives the active rod 321 to reverse. Simultaneously, the second limit sensor detects that the limit block 3241 and the operating platform 100 are not in contact on the second side of the vehicle width direction D1. Afterward, the second limit sensor also sends a signal to the second drive member, which drives the movable support leg 410 to move in the opposite direction until the rolling wheel 420 leaves the ground. Therefore, this embodiment, by adding a detection module, can achieve automatic control of the telescopic pedal device, improving its ease of operation.
[0048] See Figure 1 and Figure 5 In some embodiments, there are multiple step bodies 500, which are arranged along the extension direction of the fixed support leg 324. The more step bodies 500 there are, the smaller the step difference between them when the telescopic pedal device is in the extended state. In specific implementations, the number of step bodies 500 should be designed according to specific needs. Generally, appropriately increasing the number of step bodies 500 can reduce the risk of passengers falling and facilitate walking for the elderly, children, and passengers with mobility impairments.
[0049] See Figure 1 and Figure 5 In some embodiments, there are two linkage assemblies 320, and the fixed legs 324 of the two linkage assemblies 320 are respectively connected to both ends of the pedal body 500 in the vehicle length direction D2. In this way, the strength, structural stability and load-bearing capacity of the pedal body 500 can be improved.
[0050] See Figure 5In some embodiments, the driving rods 321 of the two linkage assemblies 320 are connected by a connecting shaft 325 at the end furthest from the corresponding driven rods 322, and the first driving member 310 is connected to the connecting shaft 325. Thus, the first driving member 310 can drive the connecting shaft 325 to rotate, and the connecting shaft 325 can drive the driven rods 322 of the two linkages to rotate. That is, one first driving member 310 can drive the movement of two linkage assemblies, reducing the number of parts and cost.
[0051] See Figure 5 In some embodiments, the movable support leg 410 extends in the same direction as the fixed support leg 324, and the movable support leg 410 and the fixed support leg 324 are slidably connected. The second driving member is a linear motor, which is installed inside the fixed support leg 324 and connected to the top end of the movable support leg 410, for driving the movable support leg 410 to slide along the extension direction of the fixed support leg 324. Thus, the ground-supporting mechanism 400 constitutes a telescopic structure. When the telescopic pedal device switches states, the second driving member can drive the movable support leg 410 to slide relative to the fixed support leg 324. By controlling the length of the bottom extension of the movable support leg 410 relative to the fixed support leg 424, the rolling wheel 420 can be switched between a state in contact with the ground and a state detached from the ground. The ground-supporting mechanism 400 of this embodiment has a simple structure, is readily available, and helps to reduce the cost of the telescopic pedal device.
[0052] In some embodiments, the surface of the pedal body is provided with anti-slip texture. The anti-slip texture can increase the friction between the pedal body and the passenger's foot, preventing the passenger from slipping and falling.
