[0025] 1. The present invention provides a pedal device, the pedal device comprising: a pedal; an active bracket, comprising a drive unit and a transmission unit, wherein: the transmission unit comprises a connecting rod structure, one end of the connecting rod structure is movably connected to the drive unit, and the other end is fixedly connected to the pedal, and is configured to enable the pedal to move between a first position and a second position under the action of the drive unit; the pedal comprises a first pedal surface and a second pedal surface; when the pedal is in the first position, the first pedal surface is substantially horizontally upward for a user to step on; when the pedal is in the second position, the second pedal surface is substantially horizontally upward for a user to step on.

[0026] 2. A pedal device provided by the present invention is provided with a guard bar, which is provided at the bottom of the pedal base, the middle of which is fixedly connected to the bottom of the pedal base, and the two ends of which are bent toward the vehicle and abut against the vehicle; and / or the length of the guard bar is not less than the length of the pedal; wherein the pedal base includes an active bracket base and / or a driven bracket base.

[0027] 3. The pedal device provided by the present invention rotates with a central rotation axis on the rotating shaft structure on the crank as the center point through a single-axis flip pedal. When the motor drives the reducer to drive the transmission unit to rotate to the retracted state of the pedal, the crank and the rocker arm are matched to the first position of the transmission unit corresponding to the retracted state of the pedal, and the driving connecting rod is connected to the pedal base at the first position of the connecting rod corresponding to the retracted state of the pedal. The rocker arm is limited and stopped, and the retracted pedal surface of the pedal is in a stepped state.

[0028] 4.

When the rotating shaft structure of the crank rotates, the crank drives the rocker arm with the bent U-shaped structure to rotate along the rotating shaft structure for a small stroke to drive the pedal to complete the flipping, thereby simplifying the structure and saving the structural space of the pedal base. The stop block on the rotating shaft structure can stop the rotation of the crank in time when the rotating shaft structure rotates, and then stop the rotation of the rocker arm; and a shock-absorbing pad is provided on the rear side wall of the connecting rod, and when the pedal is in the unfolded state of the pedal, the shock-absorbing pad on the rear side wall of the connecting rod rests on the side wall of the rocker arm, and the stopping rotating shaft structure drives the crank to drive the bent U-shaped rocker arm to make the connecting rod drive the pedal to flip, thereby preventing the rocker arm from colliding with the rotating shaft structure from the side and damaging the rocker arm, crank, rotating shaft structure and connecting rod, affecting the retraction and deployment of the pedal.

[0029] 5.

[0067] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects proposed according to the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0068] The present invention provides a pedal device, such as Figure 1-2 As shown, the pedal device is a flip-type pedal. The flip-type pedal comprises: a pedal 4; an active bracket 1, comprising a drive unit 13 and a transmission unit 131, wherein: the transmission unit 131 comprises a connecting rod structure, one end of the connecting rod structure is movably connected to the drive unit 13, and the other end is fixedly connected to the pedal 4, and is configured to move the pedal 4 between a first position and a second position under the action of the drive unit 13; the pedal 4 comprises a first pedal surface and a second pedal surface; when the pedal 4 is in the first position, the first pedal surface is substantially horizontally upward for the user to step on; when the pedal 4 is in the second position, the second pedal surface is substantially horizontally upward for the user to step on. The pedal 4 is in a retracted state in the first position, and the pedal 4 is in an extended state in the second position. The present invention simplifies the pedal structure by providing a pedal with two pedal surfaces, and by cooperating the connecting rod structure of the transmission unit with the drive unit. The single-axis flip pedal rotates around a central rotation axis through the connecting rod structure, so that the first pedal surface and the second pedal surface are located at different heights for the user to step on, thereby improving the convenience and safety of getting on and off the vehicle.

[0069] The pedal 4 can be fixedly connected to the front end of the active bracket 1. The pedal 4 can be fixedly connected to the front end of the active bracket 1 through a connecting piece. For example, screw holes are provided on the front end of the active bracket 1 and the pedal 4, and the pedal 4 is fixed to the front end of the active bracket 1 by bolts.

[0070] The active support 1 may further include an active support base, and the pedal device is fixed to the vehicle through the active support base. The structure of the active support base may be a U-shaped shell structure. The connecting rod structure may include a crank 1311, a rocker arm 1312 and a connecting rod 12, and the connecting rod 12 includes an active connecting rod and / or a driven connecting rod. The rocker arm 1312 is disposed between the crank 1311 and the connecting rod 12, and the rocker arm 1312 is movably connected to the crank 1311 through a rotating shaft structure disposed on the rocker arm 1312. The active connecting rod is rotatably connected to the front end of the U-shaped shell structure. One end of the crank 1311 is fixedly or movably connected to the output end of the drive unit. One end of the rocker arm 1312 is movably connected to the other end of the crank 1311. One end of the active connecting rod is movably connected to the rocker arm 1312, and the other end is fixedly connected to the pedal 4. The rocker arm 1312 may be movably connected to the crank 1311 through a rotating shaft structure disposed on the rocker arm 1312. The active support base is a hollow semi-enclosed shell structure for accommodating a part of the connecting rod structure. The active connecting rod is movably connected to the through hole of the U-shaped shell structure on the active support base through a rotating shaft. The drive unit 13 includes a motor 132. One end of the transmission unit 131 is fixedly connected to the pedal. When the output shaft of the motor 132 is in the same direction as the axis of the rotating shaft at the other end of the transmission unit 131, the other end of the transmission unit 131 is movably connected or fixedly connected to the output end of the motor 132 through the rotating shaft (not shown in the figure).

[0071] The pedal 4 has at least two pedal surfaces for stepping on. When the pedal 4 has two pedal surfaces for stepping on, namely the first pedal surface and the second pedal surface, the first pedal surface and the second pedal surface are two non-coplanar surfaces of the pedal 4. When the pedal 4 has two pedal surfaces for stepping on, the two pedal surfaces for stepping on can be in a non-coplanar state. The first pedal surface and the second pedal surface are not parallel. For example, there is a certain angle between the two pedal surfaces for stepping on (as shown in the figure). The angle is generally around 90° and can be based on the implementation. As a preferred embodiment, the angle is slightly less than 90°, which can prevent the outer pedal surface on the pedal 4 from protruding outward and affecting the ride. Among them, when the angle is slightly less than 90°, it can also reduce the rotation angle of the pedal 4 when it is flipped. When the motor 132 drives the transmission unit 131, the rocker arm 1312 can drive the active connecting rod to flip the pedal surface of the pedal 4, so that the two different pedal surfaces for stepping on the pedal 4 are flipped through the active connecting rod, and the flip angles of the two pedal surfaces for stepping on the pedal 4 are changed, so that the pedal surface height is adjusted and the pedal surface with a larger area is flipped and replaced, which is convenient for passengers to get on and off the vehicle. For example, when the pedal 4 is in the first position, the first pedal surface with a smaller area is located at a low position close to the ground and is basically horizontally facing upwards for users to step on; when the driving unit 13 of the active bracket 1 drives the transmission unit 131, the active connecting rod of the transmission unit 131 drives the pedal 4 to flip and adjust toward a high position away from the ground, so that the second pedal surface with an area larger than the first pedal surface is located at a high position away from the ground and is basically horizontally facing upwards for users to step on.

[0072] The first pedal surface and the second pedal surface are not parallel; and / or the widths of the first pedal surface and the second pedal surface are different. For example, the width of the second pedal surface is greater than the width of the first pedal surface, or the width of the first pedal surface is greater than the width of the second pedal surface. The arrangement is made according to actual conditions to facilitate passengers to get on and off the vehicle conveniently and safely.

[0073] In an optional embodiment of the present invention, the pedal 4 is provided with a clamping portion 41, and the front end of the active connecting rod is provided with a clamping groove 121 adapted to the clamping portion 41 of the pedal 4, and the clamping groove 121 is fixedly connected to the clamping portion 41. Figure 3 and Figure 4As shown, the clamping groove 121 is provided with multiple steps and multiple clamping grooves of different depths, and a bolt through hole is provided at the bottom of the groove. The structure of the clamping portion 41 on the pedal 4 is adapted to the structure of the clamping groove on the clamping groove 121, and the clamping portion 41 is also provided with a bolt through hole at the position corresponding to the bolt through hole on the clamping groove 121. The clamping portion 41 of the pedal 4 is fixed to the clamping groove 121 of the active connecting rod by a fixing bolt, so that the pedal 4 is fixedly connected to the active connecting rod. The pedal 4 has multiple pedal surfaces for stepping, such as a retracted pedal surface 42 and an extended pedal surface 43.

[0074] As a preferred embodiment, the retracted pedal surface 42 and the deployed pedal surface 43 may be fixed or have multiple variable fixed gears. When the retracted pedal surface 42 and the deployed pedal surface 43 are in a variable target fixed gear, the target fixed gear state can be locked by the drive unit 13 and the transmission unit 131, so that the pedal surface for stepping is in a fixed state, so that passengers can step on it when getting on and off the vehicle.

[0075] In an optional embodiment of the present invention, the flip pedal also includes a guard bar 3, which can be a columnar structure, such as a cylindrical structure or a prismatic structure, and is not limited to a solid structure or a hollow structure. The guard bar 3 is arranged at the bottom of the pedal base 11, and the guard bar 3 is provided with a bolt hole, and is fixed to the bottom of the pedal base 11 by bolts. The middle part of the guard bar 3 is fixedly connected to the bottom of the pedal base 11, and the two ends of the guard bar 3 are bent toward the vehicle direction and abut against the vehicle. Among them, the pedal base 11 includes an active support base and / or a driven support base. The guard bar 3 can be used to strengthen the protection of a single-axis flip pedal, and can also adopt an extended and extended structure to uniformly strengthen the protection of multiple single-axis flip pedals. By adding the guard bar 3, the present invention can, on the one hand, enhance the support strength of the active bracket 1, and on the other hand, it can be used as an anti-collision guard bar on the side of the vehicle to prevent the flip pedal on the side of the vehicle from being compressed and deformed, affecting its use.

[0076] In an optional embodiment of the present invention, the driving unit 13 further includes a reducer 133, such as Figure 7 and 8As shown, the reducer 133 is arranged between the transmission unit 131 and the motor 132, and the input end of the reducer 133 is movably connected to the output end of the motor 132; the output end of the reducer 133 is connected to the transmission unit 131. The reducer 133 can be a worm gear reducer, and the motor 132 and the worm gear reducer are fixedly installed on the base of the active support, and the output shaft of the motor 132 is connected to the crank 1311 through the worm gear reducer. The worm gear mechanism has a reverse self-locking function, which can prevent the external force from driving the crank 1311 connected thereto to rotate when the motor 31 is not working. That is, the worm gear reducer is used for deceleration and reversing when the transmission unit 131 moves, and self-locking when the movement stops. For example, after the crank 1311 rotates to a suitable working position, the worm gear reducer locks the crank 1311, the rocker arm 1312 movably connected to the crank 1311, and the position of the connecting rod 12 through the reverse self-locking function, so that the pedal 4 fixedly connected to the connecting rod 12 is in a locked stable state, ensuring the stability of the pedal 4 when passengers get on and off the vehicle. The worm gear reducer moves the pedal 4 between the first position and the second position, including the pedal 4 rotating under the action of the transmission unit 131, so that the horizontal upward surface of the pedal 4 switches between the first pedal surface and the second pedal surface. That is, driven by the motor 132, the worm gear reducer reverses the driving force of the transmission unit 131 to achieve the horizontal upward surface of the pedal 4 switching back and forth between the first pedal surface and the second pedal surface. In addition, the worm gear reducer can also decelerate the driving speed when the pedal 4 runs close to the first pedal surface and the second pedal surface, so that the pedal 4 can be decelerated to a locked fixed state when it runs close to the first pedal surface and the second pedal surface, thereby improving the stability and safety of the operation of the various component structures in the pedal device.

[0077] In an optional embodiment of the present invention, Figures 9 to 12As shown, when the motor 132 drives the reducer 133 to drive the transmission unit 131 to rotate to the retracted state of the pedal 4, the crank 1311 and the rocker arm 1312 are matched at the first position 131a of the transmission unit corresponding to the retracted state of the pedal 4, and the active connecting rod is at the first connecting rod position 122 corresponding to the retracted state of the pedal 4 around the rotating shaft connected to the base of the active support. A stopper 1311a is provided on the crank 1311. When the crank 1311 rotates, the rocker arm 1312 on the side of the crank 1311 moves toward the rotating shaft of the reducer 133, and at the same time drives the stopper 1311a to rotate until the stopper 1311a is driven to abut against the side wall of the rocker arm 1312 on the side of the crank 1311, and the rocker arm 1312 stops under the resistance of the stopper 1311a. The connecting rod 12 toward the side of the rocker arm 1312 moves into the active support base, the bent rocker arm 1312 structure overlaps with the crank 1311, and the bent rocker arm 1312 structure is wrapped around one side of the crank 1311. The connecting rod 12 locks and limits the fixed pedal 4 through the rocker arm 1312. At this time, the rocker arm 1312 is limited and stopped, and the retracted pedal surface 42 of the pedal 4 is in a stepped state. When the transmission unit 131 is in the first transmission unit position 131a, the transmission unit 131 cooperates with the structure of the active support base, reducing the space size of the pedal base 11, which is conducive to the flexible arrangement of the active support 1.

[0078] In an optional embodiment of the present invention, Figures 9 to 12 As shown, when the motor 132 drives the reducer 133 to drive the transmission unit 131 to rotate to the unfolded state of the pedal 4, the crank 1311 and the rocker arm 1312 cooperate with the second position 131b of the transmission unit corresponding to the unfolded state of the pedal 4, and drive the connecting rod 12 to the second position 123 of the connecting rod corresponding to the unfolded state of the pedal 4 around the rotating shaft connected to the active support base. At this time, the rocker arm 1312 and the crank 1311 open the structure of overlapping together, and the rocker arm 1312 of the curved structure moves toward the side of the connecting rod 12, and the front end of the rocker arm 1312 drives the connecting rod 12 to move outside the active support base. The rear side wall of the connecting rod 12 can be provided with a stop shock-absorbing pad (not shown in the figure), which is correspondingly against the side of the rocker arm 1312. Under the action of the connecting rod 12 and the stop shock-absorbing pad, the rocker arm 1312 is limited and stops by shock absorption. The connecting rod 12 locks and limits the connected pedal 4 through the rocker arm 1312, and the unfolded pedal surface 43 of the pedal 4 is in a stepped state. When the transmission unit 131 is in the second transmission unit position 131b, the transmission unit 131 cooperates with the structure of the pedal base 11, and the rocker arm 1312 and the connecting rod 12 can be extended out of the open pedal base 11, reducing the space size of the active bracket base, which is conducive to the flexible arrangement of the active bracket 1 with the rocker arm 1312 and the connecting rod 12.

[0079] In an optional embodiment of the present invention, Figures 13 to 17 As shown, the rocker arm 1312 has a bent U-shaped structure, and the bent U-shaped structure is adapted to the rotating shaft structure (structure of the crank shoulder) of the driving crank 1311. The crank 1311 is a double-arm structure, and the crank 1311 includes two crank arms 1311b, and a crank hole 1311d is provided in the crank shoulder connecting the two crank arms 1311b, and a crank arm hole 1311c is provided at one end of the crank arm 1311b away from the crank hole 1311d. The crank arm holes 1311c of the double crank arm structure are the same, and the axes of the two crank arm holes 1311c are consistent and parallel to the axis of the crank hole 1311d.

[0080] In the embodiment of the present invention, the U-shaped structure of the bent rocker arm 1312 is composed of a first rocker arm 1312a and a second rocker arm 1312b, the end portion of the first rocker arm 1312a is provided with a first rocker arm hole 1312c, and the end portion of the second rocker arm 1312b is provided with a second rocker arm hole 1312d. The crank hole 1311d on the crank 1311 is movably connected to the through hole provided on the pedal base 11 through a rotating shaft, and the crank arm hole 1311c on the crank 1311 is movably connected to the first rocker arm hole 1312c on the rocker arm 1312 through a rotating shaft. The second rocker arm hole 1312d on the rocker arm 1312 is movably connected to the through hole on the connecting rod 12 through a rotating shaft. The receiving groove of the bent U-shaped structure on the rocker arm 1312 can wrap a part of the structure of the crank 1311 when the pedal 4 is in a retracted state. When the pedal 4 changes from the deployed state to the retracted state, the crank 1311 drives the rocker arm 1312 to rotate, so that the end of the rocker arm 1312 connected to the active connecting rod moves toward the direction close to the crank 1311, and the receiving groove of the bent U-shaped structure on the rocker arm 1312 is almost close to and wraps part of the structure of the crank 1311. The active connecting rod rotates relative to the active support base and drives the pedal 4 to rotate to be in the retracted state. When the pedal 4 changes from the retracted state to the deployed state, the crank 1311 drives the rocker arm 1312 to rotate, so that the end of the rocker arm 1312 connected to the active connecting rod moves in the direction away from the crank 1311, driving the active connecting rod to move from the inside of the active support base through the opening of the active support base to the outside of the active support base, so as to finally drive the pedal 4 to rotate to the deployed state.

[0081] As a preferred embodiment, the length of the second rocker arm 1312b connected to the active connecting rod is greater than the length of the first rocker arm 1312a connected to the crank 1311. This arrangement is conducive to reducing the spatial size of the pedal base 11 and facilitating the flexible arrangement of the active bracket 1; on the other hand, it is conducive to the connecting rod 12 having a larger moving range, which is conducive to the adjustment of the recovery and deployment of the pedal 4 in a larger height space range when the pedal is turned over.

[0082] In an optional embodiment of the present invention, Fig.14and Fig.15 As shown, the rocker arm 1312 is a bent U-shaped rod structure or a U-shaped plate structure. When the rocker arm 1312 adopts a bent U-shaped rod structure, the structure size of the rocker arm 1312 is smaller and the layout is more flexible; when the rocker arm 1312 is a bent U-shaped plate structure, the structure of the rocker arm 1312 is more stable along the axis of the shaft, can withstand greater driving force when swinging, and can more stably lock the active state of the connecting rod 12.

[0083] In other optional embodiments of the present invention, Fig.16 and Fig.17 As shown, the rocker arm 1312 also includes a bent S-shaped rod structure or an S-shaped plate structure. The S-shaped rocker arm 1312 can further ensure the arm length of the rocker arm 1312 while reducing the height space size of the pedal base 11, thereby increasing the range of rotation adjustment of the active connecting rod.

[0084] In another optional embodiment of the present invention, Figures 1 to 17 As shown, a stop block 1311a is provided on the rotating shaft structure of the driving crank 1311. The stop block 1311a is a convex block structure, which is provided in the middle of the crank shoulder of the crank 1311, that is, the middle position beside the crank hole 1311d. A shockproof pad can be provided on the stop block 1311a, which reduces the friction and wear on the side wall of the rocker arm 1312 and the effect on the output rotating shaft of the reducer 133.

[0085] In another optional embodiment of the present invention, a flip-type electric pedal includes the flip-type pedal described in any of the above embodiments, and the flip-type pedal also includes at least one driven bracket 2 composed of a driven bracket base and a driven connecting rod. The driven bracket 2 differs from the active bracket 1 in that it does not include a drive unit and a transmission unit. The pedal 4 can be a columnar structure, the driven bracket 2 is arranged in parallel with the active bracket 1, one end of the driven connecting rod is fixedly connected to the pedal 4 of the columnar structure, and the other end is movably connected to the driven bracket. As an optional embodiment, a driven bracket 2 can be added to one side of an active bracket 1, and the driven bracket 2 is driven by the active bracket 1 to synchronously perform the flip recovery or flip unfolding of the pedal 4. The connection mode between the driven connecting rod and the pedal 4 is the same as the connection mode between the active connecting rod and the pedal 4. The driven connecting rod rotates relative to the driven bracket base as the pedal 4 rotates, thereby supporting the pedal 4. The driven bracket base and the active bracket base together constitute the pedal base structure, and the structure of the driven bracket base and the active bracket base can be the same.

[0086] As another optional implementation, Fig.18 and Fig.19As shown, a driven bracket 2 is provided on both sides of an active bracket 1, and the active bracket 1 and the driven bracket 2 are arranged in parallel and at intervals. A plurality of clamping parts 41 are provided on the pedal 4 along the length direction of the columnar structure, and the connecting rods 12 of the active bracket 1 and the driven bracket 2 correspond to the clamping parts 41 of the pedal 4 respectively and are fixed together by bolts. The driven bracket 2 is not provided with a driving unit 13, but the active bracket 1 is provided with a driving unit 13, and the driving unit 13 drives the active connecting rod to retract and unfold (as shown in FIG. 1 ). Fig.18 and Fig.19 ). The present invention expands the structure of the pedal 4 by cooperating with the driven bracket 2 and the active bracket 1, and fixes the pedal 4 at multiple force points through multiple brackets, making the pedal 4 more stable. The present invention equips the active bracket 1 with a driving unit 13 to drive the driven bracket 2 that is not equipped with a driving unit to recycle and unfold the pedal 4, so that when the pedal 4 is in the recovered state, the retracted pedal surface 42 of the pedal 4 is in a stepped state; and when the pedal 4 is in the unfolded state, the unfolded pedal surface 43 of the pedal 4 is in a stepped state. It further expands the adjustment and locking of the pedal 4 at different heights in different flipping states. For example, when the pedal 4 is in the first position, the first pedal surface with a smaller area is located at a low position close to the ground and is basically horizontally facing upwards, for users to step on; the driving unit 13 and the transmission unit 131 of the active bracket 1 drive the connecting rod 12, and the connecting rod 12 drives the pedal 4 to flip and adjust toward a high position away from the ground, so that the second pedal surface with an area larger than the first pedal surface is located at a high position away from the ground and is basically horizontally facing upwards, for users to step on, so as to meet the needs of passengers to get on and off the vehicle conveniently. In other embodiments, the area of ​​the first pedal surface can also be larger than the area of ​​the second pedal surface, and the specific implementation will not be repeated here.

[0087] In another optional embodiment of the present invention, a guard bar 3 is further provided at the bottom of the pedal base 11 of the driven bracket 2, the middle of the guard bar 3 is fixedly connected to the bottom of the pedal base 11, and the two ends of the guard bar 3 are bent toward the vehicle direction and abut against the vehicle. The guard bar 3 extends along the extension direction of the pedal 4, and fixes the active bracket 1 and the driven bracket 2 which are parallel and spaced apart on one side of the pedal 4 together, so that the active bracket 1 and the driven bracket 2 have two different fulcrums on the pedal base 11, thereby enhancing the support for the active bracket 1 and the driven bracket 2, and reducing the stress deformation of the active bracket 1 and the driven bracket 2.

[0088] In another optional embodiment of the present invention, a plurality of driven brackets 2 are arranged at intervals on both sides of the active bracket 1 along the pedal 4 of the columnar structure. The plurality of driven brackets 2 are arranged at intervals on both sides of the active bracket 1, which can further balance the balanced driving flipping of the pedal 4 by the plurality of different driven brackets 2, and balance the pressure of the pedal 4 when the pedal 4 is stepped on, so as to avoid the active bracket 1 being arranged in an asymmetric and unbalanced position, which affects the flipping and locking of the pedal 4.

[0089] The present invention also provides a vehicle, which includes a flip-type pedal including only at least one active bracket 1 in any of the above embodiments, and / or a flip-type electric pedal including at least one active bracket 1 and at least one driven bracket 2 connected and supported in any of the above embodiments.
