At the same time, a supporting force is generated in a predetermined state to adapt to the use state and In the folded state, such as when the foldable body 10 is folded, the footrest 12 is rotated and placed vertically at the end of the foldable body 10. When the foldable body 10 is in the unfolded state, the footrest 12 is rotated and can be placed flat at the end of the foldable body 10. When the user sits on the seat, the foot can be stepped on the footrest 12 to improve the comfort of use. At the same time, in order to improve the driving safety of the foldable body 10, a braking device 13 is also provided on one side of the footrest 12. At the same time, a mechanical braking structure such as a disc brake or a drum brake is installed on the wheel. The braking device 13 is connected to the mechanical braking structure on the wheel. When braking is needed, the braking device 13 can be stepped on to stop the trailer, wherein the braking device 13 can rotate relative to the foldable body 10. When the footrest 12 is in the folded state, the braking device 13 can also be in the folded state to avoid occupying space when stored.

[0032] It should be noted that the direction bar assembly 11 can be switched between a vertical state and an inclined state. The vertical state can be used for riding, etc., and the inclined state can be used for towing.

[0033] Furthermore, two pedals 12 are provided, which are respectively provided on both sides of the folding vehicle body 10, and each of the pedals 12 includes: a first pedal rod 121; one end of the first pedal rod 121 is connected to the folding vehicle body 10 for limited rotation, and the first pedal rod 121 can rotate within a predetermined vertical angle relative to the folding vehicle body 10;

[0034] Specifically, in the present embodiment, two footrests 12 are provided, one on each side of the folding body 10, wherein each footrest 12 includes a first pedal 121, wherein the first pedal 121 is rotatably connected to the folding body 10, and the first pedal 121 can rotate within a predetermined vertical angle relative to the folding body 10, and the braking device 13 is arranged on the side of the first pedal 121, and the braking device 13 rotates with the rotation of the first pedal 121, wherein the bottom surface of the first pedal 121 is hollowed out, thereby reducing the weight of the first pedal 121 and reducing the consumables of the first pedal 121, while not affecting the stability of the first pedal 121.

[0035] Furthermore, in this embodiment, the footrest 12 further includes: a second pedal rod 122, the second pedal rod 122 is rotationally connected to an end of the first pedal rod 121 away from the folding vehicle body 10, and the second pedal rod 122 can rotate within a predetermined lateral angle relative to the first pedal rod 121;

[0036] Specifically, in order to enhance the user experience, the footrest 12 also includes a second pedal rod 122. In order to adapt to the usage habits of most people, one end of the second pedal rod 122 is rotatably connected to the first pedal rod 121, and the second pedal rod 122 can rotate laterally relative to the first pedal rod 121, wherein the rotation direction of the second pedal rod 122 is toward the direction of the other second pedal rod 122, and the rotation of the second pedal rod 122 can also avoid conflict with the direction rod assembly 11 when the folding body 10 is folded. When folding is required, the second pedal rod 122 can be rotated so that it is in a straight line with the first pedal rod 121. At this time, even if the two sides move closer to the middle when the folding body 10 is folded, the second pedal rod 122 will not conflict with the direction rod assembly 11.

[0037] Furthermore, in this embodiment, a positioning lock pin 125 is further provided on the bottom surface of one end of the second pedal 122 connected to the first pedal 121, and a lock hole 126 matching the positioning lock pin 125 is provided at one end of the first pedal 121 connected to the second pedal 122, and at least one lock hole 126 is provided, and the second pedal 122 is fixed at a predetermined angle by the cooperation between the positioning lock pin 125 and the lock hole 126;

[0038] Specifically, in order to prevent the second pedal rod 122 from rotating freely relative to the first pedal rod 121, a positioning lock pin 125 is fixedly installed on the bottom surface of the second pedal rod 122, and a lock hole 126 is opened on the end surface of one end where the first pedal rod 121 and the second pedal rod 122 are connected, wherein two lock holes 126 are provided, one for making the second pedal rod 122 and the first pedal rod 121 in a straight state, and the other for making the second pedal rod 122 and the first pedal rod 121 in an inclined state, through the positioning lock pin The cooperation between 125 and the lock hole 126 fixes the second pedal rod 122 in any state to limit its movement, wherein the positioning lock pin 125 has a spring inside; and the second pedal rod 122 is provided with a plurality of leakage holes at one end away from the first pedal rod 121. Since the soles of shoes usually have anti-skid patterns, when stepping on the second pedal rod 122, part of the anti-skid patterns can be embedded in the leakage holes, thereby increasing friction and improving the anti-skid effect. The leakage holes can also prevent dust and mud on the soles from accumulating on the second pedal rod 122.

[0039] Furthermore, in this embodiment, a plurality of grooves 123 are further provided at one end where the first pedal rod 121 and the second pedal rod 122 are connected, and the plurality of grooves 123 are connected to each other, and a through hole 124 is further provided at the end of the groove 123;

[0040] Specifically, when the user steps on the pedal 12, the first pedal rod 121 is also within the pedal range. In order to prevent dust and mud from falling on the connection between the first pedal rod 121 and the second pedal rod 122 and affecting the rotation of the first pedal rod 121 and the second pedal rod 122, a plurality of grooves 123 are provided at the connection between the first pedal rod 121 and the second pedal rod 122. The grooves 123 are arranged at intervals and are interconnected. At the same time, a through hole 124 is provided at one end of the groove 123. The through hole 124 penetrates the first pedal rod 121. The groove 123 is used to allow water and mud to flow along a predetermined path, and the through hole 124 is used to allow water and mud to flow out of the first pedal rod 121 to avoid accumulation.

[0041] Furthermore, in the present embodiment, the braking device 13 comprises: a brake lever 131 and a mounting member 132; the brake lever 131 is rotationally connected to the pedal 12, the mounting member 132 is fixedly connected to the pedal 12, the mounting member 132 is spaced apart from the pedal 12, a brake line 133 is fixedly clamped on the mounting member 132, one end of the brake line 133 is rotationally connected to the brake lever 131, and the other end is connected to the wheel, when the brake lever 131 rotates, the brake line 133 is extended or retracted, and a reset spring 134 for resetting the brake lever 131 is also connected between the brake lever 131 and the mounting member 132.

[0042] Specifically, the brake device 13 is arranged on one of the foot pedals 12, the brake lever 131 is rotatably connected to the side wall of the first pedal rod 121, the mounting piece 132 is spaced apart from the brake lever 131, the mounting piece 132 is fixedly arranged on the first pedal rod 121, and a brake line 133 is fixedly arranged on the mounting piece. The inner line of the brake line 133 is rotatably connected to one end of the brake lever 131 adjacent to the mounting piece 132, and the other end of the brake line 133 is connected to the mechanical brake of the wheel. When the brake lever 131 rotates on the first pedal rod 121, the brake line 133 is pulled to drive the mechanical brake for braking. In order to enable the brake lever 131 to reset itself for the next use, a return spring 134 is also connected between the brake lever 131 and the mounting piece 132. When the brake lever 131 is in a braking state, the return spring 134 is stretched. When the brake lever 131 loses the external force, the return spring 134 pulls the brake lever 131 to reset itself.

[0043] Furthermore, in this embodiment, the end of the brake lever 131 away from the brake line 133 is upwardly tilted, and a groove 138 is provided at a position corresponding to the brake lever 131 and the pedal 12, and a limiting column 127 is provided on the pedal 12, and the limiting column 127 is located in the groove 138;

[0044] Specifically, the end of the brake lever 131 away from the brake line 133 is in an upwardly extending tilted shape, so that the brake lever 131 protrudes from the top plane of the first pedal 121 and the second pedal 122, so that the user has a certain travel before stepping on the brake lever 131 to be restricted by the first pedal 121 for braking. Preferably, the end adjacent to the mounting member 132 is also in an upwardly extending tilted shape, which is convenient for pulling out the brake line 133 and does not cause friction between the brake line 133 and the mounting member 132; and in order to avoid excessive rotation of the brake lever 131, a groove 138 is further meanderingly provided on the brake lever 131, and a limiting column 127 is provided at a predetermined position of the first pedal 121, and the limiting column 127 cooperates with the groove 138 to limit the maximum rotation angle of the brake lever 131.

[0045] Furthermore, in this embodiment, the folding body 10 has power output, and the mounting member 132 is further provided with a sensor 135, the sensor 135 is used to sense the state of the brake lever 131, and when the brake lever 131 is in a predetermined state, the sensor 135 limits the power output of the folding body 10;

[0046] Specifically, since the folding body 10 of the present embodiment has power output, in order to avoid outputting power while stepping on the brakes, a sensor 135 is further provided on the mounting member 132. The sensor 135 is connected to the power output controller of the folding body 10. The sensor 135 cooperates with the brake lever 131. When the brake lever 131 is in a braking state, the sensor 135 is triggered. The sensor 135 sends a triggering message to the controller, and the controller stops the power output, thereby avoiding the situation where the brake is in a braking state and power is still being output.

[0047] It should be pointed out that since the brake lever 131 has a movement stroke, the movement stroke corresponds to the braking force, that is, the greater the movement stroke of the brake lever 131, the greater the braking force. In order to avoid triggering the sensor 135 when the brake lever 131 is in a low stroke state, the trigger value of the sensor 135 can be adjusted, such as triggering the sensor 135 at the maximum movement stroke or triggering it when entering the last one-third of the stroke, which can be adjusted according to actual usage requirements.

[0048] Furthermore, in this embodiment, a locking lever 136 is rotatably connected to the mounting member 132, and an elastic member 137 is provided on the mounting member 132 to keep the locking lever 136 in a predetermined state. A locking groove 139 adapted to the locking lever 136 is provided on one end of the brake lever 131 facing the mounting member 132. When the brake lever 131 is in a predetermined state, the locking lever 136 is pressed against the locking groove 139.

[0049] Specifically, in order to prevent the folding vehicle body 10 from sliding when in the parking state, a locking lever 136 is rotatably connected to the mounting member, and a locking groove 139 is provided on one end of the brake lever 131 adjacent to the mounting member 132, wherein the locking lever 136 is located within the movement stroke of the brake lever 131. When the brake lever 131 is at the maximum stroke in the braking state, the brake lever 131 will push up the locking lever 136, and the end of the locking lever 136 will push against the locking groove 139, thereby limiting the movement of the folding vehicle body 10. The brake lever 131 is reset to achieve permanent braking. At the same time, an elastic member 137 is also connected to the locking lever 136. The elastic member 137 is used to provide a force to the locking lever 136 so that it is always in a coordinated state with the brake lever 131 to avoid disengagement due to vibration. When the permanent braking needs to be released, the locking lever 136 can be pressed to lift it. At this time, the brake lever 131 loses the restriction of the locking lever 136 and resets itself under the action of the reset spring 134.

[0050] In summary, the present application provides a footrest 12 on the folding body 10 to provide the user with a place to step on when riding, thereby reducing the feeling of being cramped and improving the user experience. At the same time, a brake device 13 is provided on the side of the footrest 12 to ensure the safety of riding. Both the footrest 12 and the brake device 13 can be folded to avoid occupying additional space when the folding body 10 is folded, thereby improving practicality.
