[0017] Preferably, the surface of the pedal body is provided with anti-slip patterns.
[0018] In a second aspect, the present application provides a vehicle, including the retractable pedal device provided in the first aspect of the present application.
[0019] Compared with the prior art, the retractable pedal device and the vehicle provided by the present application at least achieve the following beneficial effects:
[0020] In this application, the telescopic pedal device includes an operation platform, a platform bracket, an extension mechanism, a ground support mechanism, and a pedal body. Among them, the first side of the operation platform is connected to the vehicle, and the second side of the operation platform is connected to the pedal body through a link group. The operation platform constructs a connection structure between the vehicle and the pedal body to realize the associated interaction between the two. The platform bracket can provide reliable support for the operation platform and serve as an installation carrier for the extension mechanism. The extension mechanism includes a first driving member and a link group. The link group includes a driving rod, a driven rod, a support rod, and a fixed leg. The first driving member can drive the extension mechanism to move. Specifically, the first driving member can drive the driving rod to rotate, and the rotating driving rod can drive the driven rod to move. The moving driven rod can drive the bottom of the fixed leg to move in a direction closer to or farther from the operation platform. The fixed leg can also drive one end of the support rod to move. At the same time, because the other end of the support rod is connected to the platform bracket, the support rod also exerts a force on the fixed leg, causing the fixed leg to rotate. As a result, the top of the fixed leg can move in a direction farther from or closer to the operation platform. In the vehicle width direction, the movement directions of the bottom end and the top end of the fixed leg are opposite. When the top of the fixed leg moves in a direction closer to the operation platform until it abuts against or has a small distance from the operation platform, at this time, the fixed leg rotates to an inclined state, and the fixed leg extends outwards from a position closer to the operation platform. At this time, the telescopic pedal device is in an extended state, making the ground, the pedal body, and the operation platform have a certain step difference, making the actions of passengers getting on and off the vehicle more natural and labor-saving, improving the travel comfort, and optimizing the overall riding experience. When the top of the fixed leg moves in a direction farther from the operation platform until the fixed leg is basically perpendicular to the ground and the distance between the support rod and the platform bracket is reduced to the minimum, at this time, the distance between the pedal body and the operation platform is the closest, occupying less space, reducing the probability of collision between the telescopic pedal device and people or objects around the vehicle during driving, and having high aesthetics. The telescopic pedal device can realize the position and state switching of the pedal body through the extension mechanism and the ground support mechanism, and has a simple structure and convenient operation.
[0021] Of course, any product implementing this application does not necessarily need to achieve all the above-mentioned technical effects simultaneously.

[0038] Please refer to Figures 1 to 5, an embodiment of the present application provides a telescopic pedal device, including an operation platform 100, a platform bracket 200, an extension mechanism 300, a ground support mechanism 400, and a pedal body 500. Among them, the operation platform 100 is used to connect to the vehicle frame 101 on the first side in the vehicle width direction D1; the platform bracket 200 is connected to the operation platform 100 on the second side in the vehicle width direction D1; the extension mechanism 300 includes a first driving member 310 and a link group 320. The first driving member 310 is installed on the platform bracket 200. The link group 320 includes a driving rod 321, a driven rod 322, a support rod 323, and a fixed leg 324. The first driving member 310 is connected to one end of the driving rod 321 for driving the driving rod 321 to rotate; the other end of the driving rod 321 is rotatably connected to one end of the driven rod 322. One end of the support rod 323 is rotatably connected to the platform bracket 200, and the other end of the support rod 323 is rotatably connected to the middle of the fixed leg 324; the ground support mechanism 400 includes a second driving member, a movable leg 410, and a rolling wheel 420. The movable leg 410 is movably connected to the bottom end of the fixed leg 324. The second driving member is connected to one end of the movable leg 410 for driving the movable leg 410 to move; the bottom end of the movable 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 leg 324; the pedal body 500 is connected to the fixed leg 324.
[0039] It should be understood that the movable leg 410 is movably connected to the bottom end of the fixed leg 324, which means that the connection between the movable leg 410 and the bottom end of the fixed leg 324 can be a sliding connection. The movable leg 410 can extend out of the bottom end of the fixed leg 324. The movable leg 410 is equivalent to an extension section of the fixed leg 324 in its extending direction. The movable leg 410 can extend out of the bottom end of the fixed leg 324 by a certain distance to contact the ground, and can also retract into the bottom end of the fixed leg 324 by a certain distance to disengage from the ground; the connection between the movable leg 410 and the bottom end of the fixed leg 324 can also be a rotational connection. The movable leg 410 can rotate at the bottom end of the fixed leg 324. During the rotation of the movable leg 410, as the angle between the movable leg 410 and the fixed leg 410 changes, the movable leg 410 can rotate to contact the ground and can also rotate in the reverse direction to disengage from the ground.
[0040] The usage process of the telescopic pedal device provided in this embodiment is as follows:
[0041] When the telescopic pedal device is not working, it is in a retracted state (see Figure 1 and Figure 2 ), saving space occupancy. When the telescopic pedal device needs to be switched from the retracted state to the deployed state, first, start the second driving member. The second driving member drives the movable leg 410 to move. The movable leg 410 moves relative to the fixed leg 324 until the rolling wheel 420 connected to one end of the movable leg 410 touches the ground (seeFigure 3 ), the second driving member stops driving the movable leg 410 to move; then, the first driving member 310 is started, and the first driving member 310 drives the driving rod 321 to rotate. The driving rod 321 drives the driven rod 322 to move, and then the driven rod 322 drives the bottom end of the fixed leg 324 to move in the vehicle width direction D1 away from the platform bracket 200. The rolling wheel 420 follows the movement of the fixed leg 324 and rolls on the ground. Since both ends of the support rod 323 are rotatably connected to the platform bracket 200 and the fixed leg 324 respectively, when the bottom end of the fixed leg 324 moves in the vehicle width direction D1 away from the platform bracket 200, the support rod 323 will limit the movement of the middle part of the fixed leg 324. The support rod 323 restrains the fixed leg 324. Therefore, the fixed leg 324 will rotate. This rotation takes the rotation axis between the support rod 323 and the fixed leg 324 (i.e., the middle part of the fixed leg 324) as the axis, and the top end of the fixed leg 324 will move in the direction close to the platform bracket 200 until the gap between the top end of the fixed leg 324 and the second side of the operation platform 100 in the vehicle width direction D1 is reduced to a certain distance (even in contact with each other), and the retractable pedal device completes the switching from the retracted state to the deployed state (see Figure 4 and Figure 5 ).
[0042] When the retractable pedal device is in the deployed state (see Figure 4 and Figure 5 ), passengers can get on and off the vehicle by stepping on the pedal body 500. When the retractable pedal device needs to be switched from the retracted state to the deployed state, first, the first driving member 310 is started. The first driving member 310 rotates in the reverse direction and drives the driving rod 321 to rotate. The driving rod 321 drives the driven rod 322 to move, and then the driven rod 322 drives the bottom end of the fixed leg 324 to move in the vehicle width direction D1 close to the platform bracket 200. The rolling wheel 420 follows the movement of the fixed leg 324 and rolls on the ground. Among them, since both ends of the support rod 323 are rotatably connected to the platform bracket 200 and the fixed leg 324 respectively, the fixed leg 324 is supported by the support rod 323, and the fixed leg 324 rotates. The top end of the fixed leg 324 moves in the direction away from the platform bracket 200. In this way, the driven rod 322 and the support rod 323 continue to drive the fixed leg 324 to move. The fixed leg 324 rotates and moves in the vehicle width direction D1 close to the platform bracket 200 until the fixed leg 324 is substantially perpendicular to the ground and the distance between the support rod 323 and the platform bracket 200 is reduced to the minimum (see Figure 3 ). Then, the second driving member is started, and the second driving member drives the movable leg 410 to move. The movable leg 410 moves relative to the fixed leg 324 until the rolling wheel 420 connected to one end of the movable leg 410 rises and leaves the ground (seeFigure 1 and Figure 2 ), the telescopic pedal device completes the switching from the deployed state to the retracted state.
[0043] In this embodiment, the telescopic pedal device includes an operation platform 100, a platform bracket 200, an extension mechanism 300, a ground support mechanism 400, and a pedal body 500. Among them, the first side of the operation platform 100 is connected to the vehicle, and the second side of the operation platform 100 is connected to the pedal body 500 through a link group 320. The operation platform 100 constructs a connection structure between the vehicle and the pedal body 500 to realize the associated interaction between the two. The platform bracket 200 can provide reliable support for the operation platform 100 and provide an installation carrier for the extension mechanism 300. The extension mechanism 300 includes a first driving member 310 and a link group 320. The link group 320 includes a driving rod 321, a driven rod 322, a support rod 323, and a fixed 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 leg 324 to move in a direction closer to or farther from the operation platform 100. The fixed 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 bracket 200, the support rod 323 also exerts a force on the fixed leg 324, causing the fixed leg 324 to rotate. Furthermore, the top end of the fixed leg 324 can move in a direction farther from or closer to the operation platform 100. In the vehicle width direction D1, the moving directions of the bottom end and the top end of the fixed leg 324 are opposite. When the top end of the fixed leg 324 moves in a direction closer to the operation platform 100 until it abuts against or has a small distance from the operation platform 100, at this time, the fixed leg 324 rotates to an inclined state, and the fixed leg 324 extends out from a position close to the operation platform 100. At this time, the telescopic pedal device is in the extended state, making the ground, the pedal body 500, and the operation platform 100 have a certain step difference, making the actions of passengers getting on and off the vehicle more natural and labor-saving, improving the travel comfort, and optimizing the overall riding experience. When the top end of the fixed leg 324 moves in a direction farther from the operation platform 100 until the fixed leg 324 is substantially perpendicular to the ground and the distance between the support rod 323 and the platform bracket 200 is reduced to the minimum, at this time, the distance between the pedal body 500 and the operation platform 500 is the closest, occupying less space, reducing the probability of collision between the telescopic pedal device and people or objects around the vehicle during driving, and having high aesthetics. The telescopic pedal device can realize the position and state switching of the pedal body 500 through the extension mechanism 300 and the ground support mechanism 400, and its structure is simple and the operation is convenient.
[0044] In addition, the ground support mechanism 400 includes a second driving member, a movable leg 410, and a rolling wheel 420. The second driving member can drive the movable leg 410 to move relative to the fixed leg 324, so that the rolling wheel 420 at the bottom end of the movable leg 410 can be switched between the states of touching the ground and leaving the ground. When the rolling wheel 420 touches the ground, the rolling wheel 420 and the movable leg 410 can jointly provide support for the fixed leg 324. When the rolling wheel 420 leaves the ground, it can avoid the friction and contact between the rolling wheel 420 and the ground (or ground objects) during the vehicle driving process.
[0045] It should be noted that when the telescopic pedal device is switched from the retracted state to the extended state, the ground support mechanism 400 needs to be executed prior to the extension mechanism 300. When the telescopic pedal device is switched from the retracted state to the extended state, the extension mechanism 300 needs to be executed prior to the ground support mechanism 400. In this way, during the movement of the fixed leg 324, rolling friction can be formed between the movable leg 410 and the ground, which can reduce the friction between the movable leg 410 and the ground.
[0046] See Figures 1 to 5 , in some embodiments, a limiting block 3241 is provided at one end of the fixed leg 324 away from the movable leg 410. The telescopic pedal device further includes a detection module, and the detection module includes a first limit sensor and a second limit sensor that are electrically connected to each other. The first limit sensor is electrically connected to the rolling wheel 420 and is used to detect whether the rolling wheel 420 contacts the ground. The second limit sensor is electrically connected to the limiting block 3241 and is used to detect whether the limiting block contacts the second side of the operation platform 100 in the vehicle width direction D1. The first limit sensor is electrically connected to the first driving member 310 and the second driving member, and the second limit sensor is electrically connected to the first driving member 310 and the second driving member.
[0047] In this embodiment, the telescopic pedal device further includes a detection module. The detection module includes a first limit sensor and a second limit sensor that are electrically connected to each other. The first limit sensor and the second limit sensor can timely send corresponding signals to the first driving member 310 and the second driving member, so that the first driving member 310 and the second driving member can make timely reaction actions. Specifically, when the telescopic pedal device switches from the retracted state to the extended state, the second driving member drives the movable leg 410 to move. When the first limit sensor detects that the rolling wheel 420 contacts the ground, the first limit sensor can send a signal to the second driving member. After receiving the signal, the second driving member can stop driving the movable leg 410 to continue moving. In addition, the first limit sensor can also send a signal to the first driving member 310. After receiving the signal, the first driving member 310 can start driving the driving rod 321 to rotate until the second limit sensor detects that the limit block 3241 contacts the second side of the operation 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 can send a signal to the first driving member 310. After receiving the signal, the first driving member can drive the driving rod 321 to reverse. At the same time, the second limit sensor can detect that there is no contact between the limit block 3241 and the second side of the operation platform 100 in the vehicle width direction D1. After that, the second limit sensor can also send a signal to the second driving member, and the second driving member drives the movable leg 410 to move in the reverse direction until the rolling wheel 420 leaves the ground. It can be seen that by adding a detection module in this embodiment, the automatic control of the telescopic pedal device can be realized, and the operation convenience of the telescopic pedal device can be improved.
[0048] See Figure 1 and Figure 5 , in some embodiments, the number of the tread bodies 500 is multiple, and the multiple tread bodies 500 are arranged along the extending direction of the fixed leg 324. The more the number of the tread bodies 500, the smaller the step difference between the multiple tread bodies 500 when the telescopic pedal device is in the extended state. In specific implementation, the number of the tread bodies 500 should be designed according to specific requirements. Generally speaking, appropriately increasing the number of the tread bodies 500 can reduce the risk of passengers tripping and facilitate the walking of the elderly, children and passengers with inconvenient behaviors.
[0049] See Figure 1 and Figure 5 , in some embodiments, the number of the link groups 320 is two, and the fixed legs 324 of the two link groups 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 active rods 321 of the two connecting rod groups 320 are connected by a connecting shaft 325 at one end away from the corresponding driven rod 322, and the first driving member 310 is connected to the connecting shaft 325. In this way, 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 connecting rods to rotate, that is, one first driving member 310 can drive the two connecting rods to move, reducing the number of parts and costs.
[0051] See also Figure 5 In some embodiments, the movable leg 410 has the same extension direction as the fixed leg 324, and the movable leg 410 is slidably connected to the fixed leg 324. The second driving member is a linear motor, which is installed in the fixed leg 324 and connected to the top of the movable leg 410, and is used to drive the movable leg 410 to slide along the extension direction of the fixed leg 324. In this way, the ground-supporting mechanism 400 constitutes a telescopic structure. When the telescopic pedal device switches states, the second driving member can drive the movable leg 410 to slide relative to the fixed leg 324. By controlling the extension length of the bottom end of the movable leg 410 relative to the fixed leg 424, the rolling wheel 420 can be switched between the state of contacting the ground and the state of leaving the ground. The ground-supporting mechanism 400 of this embodiment has a simple structure and is easy to obtain, which is conducive to reducing the cost of the telescopic pedal device.
[0052] In some embodiments, the surface of the pedal body is provided with anti-skid patterns, which can increase the friction between the pedal body and the soles of the passengers' feet, thus preventing the passengers from slipping.
