As shown in Fig. 1 to Fig. 10, the present invention provides a passenger pedal, characterized in that it comprises: a pedal body 11, a folding body 10, the bottom of the pedal body 11 is movably connected to at least one pedal wheel 111, the pedal body 11 is foldably provided with a direction rod 12 for controlling the steering of the pedal wheel 111, and both ends of the pedal body 11 are respectively provided with a body connecting portion 13; the folding body 10 is foldable, one end of the folding body 10 is provided with a fixed wheel 101, and the other end is provided with a direction wheel 102, the body connecting portion 13 is rotatably connected to the fixed wheel 101, and the pedal body 11 can be vertically rotated relative to the fixed wheel 101;

Specifically, the folding vehicle body 10 is a frame-shaped vehicle body that can be folded to reduce the overall size and area. The folding method can be a folding type or a gathering type. Both of these folding methods are common existing structures, so they are not described here. In this embodiment, the folding vehicle body 10 needs to have a steering wheel 102 at one end, preferably a universal wheel, which is free to steer, and the other end needs to be a fixed wheel 101, that is, its direction is fixed; at least one pedal wheel 111 is movably installed at the bottom of the pedal body 11, and the pedal wheel 111 can be rotated vertically and horizontally relative to the pedal body 11. The vertical rotation can make the pedal wheel 111 stick to the bottom of the pedal body 11 in a folded shape, and the horizontal rotation is convenient for changing the driving direction of the pedal body 11. A steering rod 12 is also connected to the pedal body 11. The steering rod 12 can be folded to shorten the overall length of the steering rod 12 for easy storage. The steering rod 12 is connected to the pedal wheel 111 to control the steering of the pedal wheel 111 The pedal body 11 is provided with a vehicle body connecting part 13 at both ends of one side of the pedal body 11, and the vehicle body connecting part 13 extends out of the pedal body 11, and the end of the vehicle body connecting part 13 away from the pedal body 11 is rotatably connected to the fixed wheel 101. Preferably, the vehicle body connecting part 13 is rotatably connected to the wheel axle of the fixed wheel 101, so that the vehicle body connecting part 13 can drive the pedal body 11 to rotate vertically relative to the fixed wheel 101, so that when passing through some potholes or uphill, the pedal body 11 can be lifted or sunk around the wheel axle of the fixed wheel 101 to prevent the fixed wheel 101 from leaving the ground. At the same time, the connection between the vehicle body connecting part 13 and the wheel axle of the fixed wheel 101 can lower the center of gravity height of the pedal assembly, so that when the foldable vehicle body 10 is going uphill or passing some speed bumps, the foldable vehicle body 10 will not be overturned due to the weight of the person standing on the pedal assembly; the vehicle body connecting part 13 can also be connected to the wheel fork of the fixed wheel 101, and the position adjacent to the wheel axle can ensure the same effect. If the position is too high, it is easy to cause the above-mentioned rollover.

It should be noted that the wheel fork of the fixed wheel 101 can use a slanted fork structure, which can move the fixed wheel outward so that the tail of the folding body 10 is between the steering wheel 102 and the fixed wheel 101, further reducing the risk of rollover.

Furthermore, the pedal wheels 111 are provided with two, each of which is connected to a pedal wheel fork 112, the top of which is rotatably connected to a first connecting member 113, the pedal wheel fork 112 can rotate vertically relative to the first connecting member 113, the top of the first connecting member 113 is rotatably connected to the pedal body 11, the first connecting member 113 can rotate horizontally relative to the pedal body 11, the side of the first connecting member 113 is also connected to a wheel swing arm 114, and a direction transmission rod 115 is also connected between the two wheel swing arms 114;

Specifically, in the present embodiment, there are preferably two pedal wheels 111, which help to improve the stability of the pedal body 11 when in use, wherein each pedal wheel 111 is connected to a pedal wheel fork 112, and a first connecting member 113 is rotatably connected to the top of the pedal wheel fork 112, and the pedal wheel fork 112 can drive the pedal wheel 111 to rotate vertically relative to the first connecting member 113. When not in use, the pedal wheel 111 can be laid flat and folded, wherein the pedal wheel 111 can rotate at an angle of 90°, and the top of the first connecting member 113 is rotatably connected to the pedal body 11, and the first connecting member 113 can rotate horizontally relative to the pedal body 11, so as to facilitate the adjustment of the direction of the pedal wheel 111, and a horizontally extending wheel swing arm 114 is also provided on the first connecting member 113; a direction transmission rod 115 is connected between the wheel swing arms 114 of the two pedal wheels 111 for synchronously controlling the steering of the two pedal wheels 111.

Further, a hook 116 is rotatably provided on one side of the first connecting member 113, a hook holding portion of the hook 116 is spaced apart from a side wall of the first connecting member 113, a compression spring 118 is provided between the hook 116 and the first connecting member 113, a hook hole 117 adapted to the hook 116 is provided on the pedal fork 112, and the hook 116 and the hook hole 117 are snap-fitted when the pedal fork 112 is perpendicular to the pedal body 11;

Specifically, since the pedal wheel 111 can rotate vertically relative to the first connecting member 113, in order to avoid affecting normal use, a hook 116 is rotatably connected to one side of the first connecting member 113, and the hook 116 is spaced apart from the first connecting member 113. A compression spring 118 is also provided between the hook 116 and the first connecting member 113. The compression spring 118 is used to make the hook 116 always have a force to move away from the first connecting member 113. At the same time, a hook hole 117 adapted to the hook 116 is opened on the top surface of the pedal wheel fork 112. When in the vertical state, the hook 116 is located in the hook hole 117 and is snap-fitted with the hook hole 117 to fix the pedal wheel 111 and limit its vertical rotation relative to the first connecting member 113 to ensure normal use. When the pedal wheel 111 needs to be folded, it is only necessary to press the hook 116 to squeeze the compression spring 118, and the end of the hook 116 will be disengaged from the hook hole 117 to rotate the pedal wheel 111. When the hook 116 loses external force, it will reset itself under the restoring force of the compression spring 118 to facilitate the next cooperation.

Further, in the present embodiment, a transfer member 121 is rotatably provided at the bottom of the direction rod 12, the transfer member 121 passes through the pedal body 11, the direction rod 12 can be vertically rotated relative to the transfer member 121, the transfer member 121 can be horizontally rotated on the pedal body 11, the bottom of the transfer member 121 is connected to a transmission gear 20, the middle of the direction transmission rod 115 is rotatably connected to a direction swing arm 122, the end of the direction swing arm 122 away from the direction transmission rod 115 is connected to a driven gear 21, the driven gear 21 is also rotatably connected to the pedal body 11 through a rotating shaft, and the transmission gear 20 is transmission-connected to the driven gear 21;

Specifically, the adapter 121 is disposed on one side of the pedal body 11, and the adapter 121 can rotate horizontally relative to the pedal body 11. The bottom of the adapter 121 is located below the pedal body 11 and is connected to the transmission gear 20. A direction swing arm 122 is rotatably connected to the middle of the direction transmission rod 115, and a driven gear 21 is fixedly connected to the end of the direction swing arm 122 away from the direction transmission rod 115, wherein the driven gear 21 is also rotatably connected to the pedal body 11 through a rotating shaft, and the driven gear 21 can rotate in situ relative to the pedal body 11. , the displacement of the driven gear 21 can be avoided, and the transmission gear 20 is connected to the driven gear 21 in transmission connection. When the direction rod 12 rotates horizontally on the pedal body 11 through the adapter 121, the transmission gear 20 is driven to rotate synchronously. The transmission gear 20 synchronously drives the driven gear 121 to rotate, and drives the direction swing arm 122 connected thereto to rotate. Since the direction swing arm 122 is rotationally connected to the direction transmission rod 115, the direction swing arm 122 can push the direction transmission rod 115 to move left and right, thereby driving the two pedal wheels 111 to turn.

It should be noted that the direction transmission rod 115 can also be divided into two, one end of the two direction transmission rods 115 is stacked, and the two direction transmission rods 115 can rotate relative to each other, so as to avoid the steering being hindered due to the slanted direction transmission rod 115 when the steering angles of the two wheels are inconsistent; and when the direction transmission rod 155 is divided into two, the steering of the pedal wheel 111 can adopt the Ackerman steering principle to reduce the friction loss of the pedal wheel 111.

Furthermore, since the transmission gear 20 is directly connected to the driven gear 21, the direction of the pedal wheel 111 will be consistent with the direction of the direction rod 12, that is, when the direction rod 12 turns left, the pedal wheel 111 will turn left. In this case, the folding body 10 turns right, which is contrary to the steering habits of traditional vehicles and is prone to safety hazards. To avoid this situation, a reverse gear 22 is provided between the transmission gear 20 and the driven gear 21. The reverse gear 22 is meshed with the transmission gear 20, and the reverse gear 22 is also rotatably connected to the pedal body 11 through a rotating shaft. To ensure that the rotation angle of the direction rod 12 is equal to the rotation angle of the pedal wheel 111, the gear ratio of the reverse gear 22 to the transmission gear 20 is 1:1. The reverse gear 22 and the driven gear 21 are connected together by a belt or chain, so that when the direction rod 12 turns left, the pedal wheel 11 turns right, pushing the folding body 10 to turn left with the directional wheel as the rotation center.

It should be pointed out that the transmission connection between the direction rod 12 and the pedal wheel 111 can also be in the form of a transmission shaft, that is, the transmission gear 20 is changed into a bevel gear, and the driven gear 21 is also changed into a bevel gear. A transmission rod with bevel gears at both ends is set between the two bevel gears to connect the two together. The characteristic of the bevel gear that can change the transmission direction is utilized to connect the direction rod 12 and the pedal wheel 11 together.

Furthermore, in this embodiment, the end of the direction rod 12 away from the adapter 121 is rotatably connected to a telescopic rod 124, and the telescopic rod 124 can be vertically rotated relative to the direction rod 12. A handle is provided on the top of the telescopic rod 124, and a plurality of control buttons 125 are provided on the handle. A brake handle 126 is also provided on the handle, and the brake handle 126 is connected to the pedal wheel 111.

Specifically, the top of the direction rod 12 is also rotatably connected to a telescopic rod 124, which can be extended to adjust the height to suit people of different heights, and the telescopic rod 124 can also be rotated vertically relative to the direction rod 12, so that when in use, the overall length of the direction rod 12 can be further shortened, so that its length is close to the width of the pedal body 11, thereby facilitating storage and carrying. A handle is also provided at the top of the telescopic rod 124, and a plurality of control buttons 125 are provided on the handle. The functions of the plurality of control buttons 125 include but are not limited to: horn, light, forward/reverse mode switching, speed gear, etc. Such functions are all common existing technologies, so they will not be described in detail here. A switch cylinder can also be provided on the handle to control the speed change after power is connected. At the same time, a brake handle 126 is also provided on the handle, and the brake handle 126 is connected to the pedal wheel 111. The pedal wheel 111 needs to have a mechanical brake such as a disc brake or a drum brake for braking; an electric brake can also be used.

Furthermore, a limiting sleeve 129 is sleeved on the direction rod 12, and the limiting sleeve 129 is used to limit the rotation of the direction rod 12 relative to the adapter 121;

Specifically, since the direction rod 12 and the adapter 121 are rotatably connected, in order to avoid affecting the normal use of the direction rod 12, a limiting sleeve 129 is also provided on the direction rod 12. By placing the limiting sleeve 129 at the connection between the direction rod 12 and the adapter 121, the direction rod 12 is restricted from rotating relative to the adapter 121, ensuring that the direction rod 12 does not rotate vertically during normal use.

Furthermore, in this embodiment, the pedal body 11 and/or the folding vehicle body 10 is provided with a controller 127 and a power source 128, the power source 128 is connected to the controller 127, and the pedal wheel 111 and/or the fixed wheel 101 are respectively connected to the controller 127;

Specifically, in order to improve the convenience of use, the pedal body 11 and the folding body 10 can choose to install the controller 127 and the power supply 128, or both of them have the controller 127 and the power supply 128. When only the folding body 10 has the controller 127 and the power supply 128, the handle is connected to the controller 127 through a wire, and the control function of the controller 127 is intervened, so that the manned pedal can directly control the travel of the folding body 10. When only the pedal body 11 has the controller 127 and the power supply 128, there is no need to be electrically connected to the folding body 10, and the folding body 10 can be directly pushed forward by the pedal body 11; when both have the controller 127 and the power supply 128, the circuits of the two need to be connected together through a wire so that both can control each other. At this time, the user can choose one to control according to needs.

It should be pointed out that when the folding body 10 is powered, the fixed wheel 101 needs to be a wheel with a hub motor inside so that it can generate power for moving. When the pedal body 11 is powered, the pedal wheel 111 needs to be a wheel with a hub motor inside so that it can generate power for moving. The hub motor is a common existing technology, so it will not be described here.

Further, in this embodiment, one side of the pedal body 11 provided with the vehicle body connecting portion 13 is provided with two spaced connection blocks 14, the vehicle body connecting portion 13 is rotatably connected to the connection block 14, the vehicle body connecting portion 13 can be vertically rotated relative to the connection block 14, and the connection block 14 is provided with a limiting structure, and the limiting structure is used to limit the rotation of the vehicle body connecting portion 13 relative to the connection block 14;

Specifically, the connection between the vehicle body connection part 13 and the pedal body 11 can be an integrated connection or a rotational connection. In the present application, a rotational connection is preferred to reduce its volume. Specifically, the pedal body 11 is provided with two spaced connection blocks 14 on one side of the vehicle body connection part 13. The two connection blocks 14 are integrated with the pedal body 11. The vehicle body connection part 13 is rotationally connected to the connection blocks 14. The vehicle body connection part 13 can be rotated vertically relative to the connection blocks 14 so that it can be folded under the pedal body 11. At the same time, since the vehicle body connection part 13 and the connection block 14 are rotationally connected, in order to avoid affecting normal use, a limiting structure is also provided on the connection block 14. The limiting structure is mainly used to limit the rotation of the vehicle body connection part 13 so that it can always remain in the required position.

Further, the limiting structure includes: a limiting column 142, the connecting block 14 is provided with a transverse slide groove 141, the limiting column 142 is movably arranged in the transverse slide groove 141, the middle of the connecting block 14 is also provided with a vertical hole 144, an unlocking handle 143 is rotatably installed in the vertical hole 144, one end of the unlocking handle 143 is fixedly connected to the limiting column 142, and the unlocking handle 143 is also connected to a handle tension spring 145 on a side facing the folding body 10, and the end of the body connecting part 13 connected to the connecting block 14 is provided with two limiting grooves 136;

Specifically, the connecting block 14 is provided with a transverse slot 141 that penetrates the connecting block 14 along the width direction, and the limiting column 142 is slidably arranged in the transverse slot 141. The limiting column 142 can slide in the transverse slot 141. At the same time, a vertical hole 144 is provided in the middle of the connecting block 14, and an unlocking handle 143 is rotatably connected in the vertical hole 144. The limiting column 142 passes through the unlocking handle 143 and is slidably connected to the unlocking handle 143. The limiting column 142 can slide vertically relative to the unlocking handle 143. When the unlocking handle 143 rotates relative to the connecting block 14, the limiting column 142 synchronously slides in the transverse slot 141 and the unlocking handle 143, so that it moves along the transverse slot 141, wherein the two ends of the limiting column 142 are located in the transverse slot 1 41, and two limiting grooves 136 are provided at one end where the vehicle body connecting part 13 is connected to the connecting block 14, and the two limiting grooves 136 are adapted to the limiting posts 142, and the rotation of the vehicle body connecting part 13 is limited by the cooperation between the limiting posts 142 and the limiting grooves 136. In order to realize the automatic cooperation of the limiting posts 142, a handle tension spring 145 is connected to the side of the unlocking handle 143 facing the folding body 10, and the other end of the handle tension spring 145 is connected to the connecting block 14. When the handle tension spring 145 is rotated by an external force, the handle tension spring 145 is stretched to generate a restoring force. When the handle tension spring 145 is subjected to an external force, the unlocking handle 143 will automatically return to its original position under the restoring force of the handle tension spring 145, and the limiting posts 142 will be driven to return to their original position at the same time.

Further, a slot 131 is provided at one end of the vehicle body connection part 13 away from the pedal body 11, and an embedding slot 132 is provided at one end of the vehicle body connection part 13 provided with the slot 131, and the embedding slot 132 intersects with the slot 131, and a bayonet 137 is slidably provided in the embedding slot 132, and the bayonet 137 can be inserted into the slot 131, and a pull wire 133 is connected to the tail end of the bayonet 137, and a spring 134 is further provided in the bayonet 137, and the spring 134 is used to move the bayonet 137 in the direction where the slot 131 is located;

Specifically, the vehicle body connecting part 13 can be two or one at each end. In order to improve stability, two are used at each end. The ends of the two vehicle body connecting parts 13 away from the connecting block 14 are respectively provided with a card slot 131, and the card slot 131 is adapted to the wheel axle of the fixed wheel 101. The vehicle body connecting part 13 is rotatably connected to the fixed wheel 101 through the card slot 131. An embedding groove 132 is also provided at the end of the vehicle body connecting part 13 provided with the card slot 131. A card pin 137 is slidably placed in the embedding groove 132. The end of the card pin 137 adjacent to the card slot 131 can be inserted into the slot. When the vehicle body connecting part 13 is placed on the wheel axle of the fixed wheel 101 through the card slot 131 When the locking pin 137 is in a state of being moved, the locking pin 131 is in a state of being moved in a direction parallel to the locking pin 132. When the locking pin 137 is in a state of being moved, the locking pin 131 is in a state of being moved in a direction parallel to the locking pin 132. When the locking pin 137 is in a state of being moved, the locking pin 131 is in a state of being moved in a direction parallel to the locking pin 132. When the locking pin 137 is in a state of being moved, the locking pin 131 is in a state of being moved in a direction parallel to the locking pin 132.

Furthermore, in this embodiment, the vehicle body connection portion 13 is also rotatably connected to an unlocking handle 135, and one end of the unlocking handle 135 is fixedly connected to the pull wire 133;

When the unlocking handle 135 is bent, the unlocking handle 135 will pull the pull wire 133, and the pull wire 133 will drive the pin 137 to retract into the embedded groove 132. When the pin 137 retracts, the spring 134 will be squeezed synchronously to generate a restoring force. When the unlocking handle 135 loses external force, the pin 137 will be inserted back into the slot 131 by itself under the action of the spring 134, and at the same time drive the unlocking handle 135 to return to its original position by itself.

Furthermore, in the present embodiment, the end of the folding body 10 away from the pedal body 11 is also movably connected to a handle 103. Specifically, in order to facilitate towing the folding body 10 when not riding, the end of the folding body 10 away from the pedal body 11 is also connected to a handle 103, and the handle 103 can be vertically rotated relative to the folding body 10 to adjust the inclination angle of the handle 103 when towing.

It should be pointed out that since the body connecting portion 13 and the axle of the fixed wheel 101 are rotatably connected, in order to prevent the pedal body 11 from flipping over by itself in the folded state as shown in FIG. 10 , a hook (not shown in the figure) may be provided at the top of one end of the folding body 10 connected to the pedal body 11 to fix the pedal body 11 when the pedal body 11 is not in use and is folded at the rear of the folding body 10 to prevent it from flipping over.

In summary, the present invention connects a passenger pedal to the rear end of the foldable vehicle body 10 so that the foldable vehicle body 10 can carry the user for walking, which is more convenient and labor-saving to use, thereby improving the user experience, and will not affect the carrying capacity of the foldable vehicle body 10, thereby improving practicality; and the passenger pedal is rotatably connected to the axle of the fixed wheel 101 of the foldable vehicle body 10, thereby lowering the height of the force application point of the passenger pedal and effectively reducing the risk of rollover; and the passenger pedal is rotatably connected to the foldable vehicle body 10, thereby effectively avoiding force concentration at the connection point and extending the service life.
