Description

Technical Field

[0001] The utility model relates to the technical field of foldable electric trailers, in particular to a foldable electric trailer with a foldable passenger pedal. Background Art

[0002] A foldable trailer is a foldable and towable cargo vehicle. It is widely used in transporting things because of its simple use, ability to carry cargo, convenient storage, and time-saving and labor-saving properties. It is now often used in outdoor activities or short-distance transportation.

[0003] At present, most of the existing folding electric trailers only have electric power assistance, such as Patent No. CN202220922980.0 (power-assisted trailer). Although this type of trailer has improved convenience and is easier to use, it is known from the contents recorded in its specification and the drawings in the specification that it cannot carry people, and when in use, it still requires manual traction and requires the user to walk on foot, which can easily make the user feel tired and the user experience is not good. For this reason, the inventor has designed a folding electric trailer with sliding wheels, such as Patent No. CN202310568322.5 (a folding electric trailer with sliding wheels). A foldable pedal assembly is arranged at the front end of the folding body, and wheels are slidably arranged under the pedal assembly. When in use, the pedal assembly is unfolded and Sliding wheels can carry people. This type of trailer can achieve both electric power assistance and the function of carrying people, which greatly improves the convenience of use. It can also be folded up when not in use to reduce the overall size and improve the convenience of carrying. However, in actual use, the inventor found that although this solution uses smooth wheels to keep the wheels on the ground when folded and can be towed according to usage needs, this method uses a sliding connection. In order to avoid affecting normal use, a limiting structure is required to limit the sliding of the wheels. In order to improve the convenience of unlocking and locking the wheels, the locking of the limiting structure needs to be linked with the sliding of the wheels. Therefore, the structure will be relatively complicated. In addition, due to the open design of the sliding structure, foreign objects are easily introduced, resulting in unsmooth sliding, affecting the user experience.

[0004] Therefore, it is urgent to design a foldable electric trailer with a foldable passenger pedal to overcome the above-mentioned deficiencies of one or more prior arts. Utility Model Content

[0042] like Figure 1-Figure 12 As shown, the utility model provides a foldable electric trailer with a foldable passenger pedal, characterized in that it includes: a foldable body 10, support rods 11 are respectively provided on both sides of the front and rear ends of the foldable body 10, and the two support rods 11 at at least one end are respectively rotatably connected to a folding pedal rod assembly 20, the folding pedal rod assembly 20 is arched and folded from the middle part, and the end of the folding pedal rod assembly 20 away from the support rod 11 is rotatably connected to a control mechanism 30, and the support rod 11 is also rotatably connected to a first limiting rod 24, and the end of the first limiting rod 24 away from the support rod 11 is rotatably connected to the middle part of the folding pedal rod assembly 20, and the two ends of the control mechanism 30 are respectively rotatably connected to second limiting rods 25, and the second limiting rod 2 The end away from the control mechanism 30 is rotatably connected to the middle of the folding pedal lever assembly 20, the rotation centers of the first limiting rod 24 and the second limiting rod 25 are not coaxial with the rotation center of the folding pedal lever assembly 20, a first wheel 35 is provided below the control mechanism 30, the first wheel 35 is also in transmission connection with the control mechanism 30, a second wheel 13 is provided at the bottom of the folding vehicle body 10, the first wheel 35 and the second wheel 13 are arranged at intervals, the folding vehicle body 10 is also provided with a controller 14 and a battery 15 for controlling the operation of the first wheel 35 and / or the second wheel 13, and the folding pedal lever assembly 20 is arched from the middle and folded in half to pull the control mechanism 30 toward the direction of the folding vehicle body 10;

[0043] Specifically, the folding vehicle body 10 can be a folding type vehicle body or a gathering type vehicle body. The folding type vehicle body is folded from the front and back to the middle, and the gathering type vehicle body is gathered from the front and back, left and right to the middle. Since the folding type vehicle body does not need to be folded in the left and right directions, the folding type vehicle body structure is relatively simple, so this embodiment is described by taking the folding type vehicle body as an example; the folding vehicle body 10 is provided with four support rods 11, which are respectively located on both sides of the front end and the rear end of the folding vehicle body 10, wherein the bottom end of the support rod 11 is limitedly rotatably connected to the folding pedal rod assembly 2 0, the folding pedal rod assembly 20 can be arched from the middle and folded in half, the folding pedal rod assembly 20 can rotate relative to the support rod 11, the folding pedal rod assembly 20 can be provided with only two and located at one end of the folding body 10 or a group of two is located at the front end or the rear end of the folding body 10 respectively, which can be determined according to actual use requirements, and the folding pedal rod assembly 20 is also connected to the control mechanism 30 at one end away from the support rod 11. The folding pedal rod assembly 20 can rotate relative to the control mechanism 30, and when the folding pedal rod assembly 20 is arched from the middle and folded in half, the two ends are synchronously moved. The support rod 11 and the control mechanism 30 are rotated. Due to the folding of the folding pedal rod assembly 20, the distance between the two ends thereof is shortened, thereby pulling the control mechanism 30 to move in the direction of the folding vehicle body 10. When the folding pedal rod assembly 20 is flattened, it pushes the control mechanism 30 to move in the direction away from the folding vehicle body 10. A first limiting rod 24 and a second limiting rod 25 are further provided below the folding pedal rod assembly 20. One end of the first limiting rod 24 is rotatably connected to the support rod 11, and the other end is rotatably connected to the folding pedal rod assembly 20. One end of the second limiting rod 25 is rotatably connected to the control mechanism The first limit rod 24 and the second limit rod 25 are rotatably connected to the folding pedal rod assembly 20, and the other end is rotatably connected to the folding pedal rod assembly 20, and the rotation center of the first limit rod 24 and the second limit rod 25 are not coaxial with the rotation center of the folding pedal rod assembly 20, so that the synchronization of the two ends of the folding pedal rod assembly 20 is ensured by the first limit rod 24 and the second limit rod 25, and the second limit rod 25 can also limit the rotation of the control mechanism 30 relative to the folding pedal rod assembly 20, so as to avoid the rotation of the control mechanism 30 relative to the folding pedal rod assembly 20 when in use or folding due to the rotation connection between the control mechanism 30 and the folding pedal rod assembly 20;A first wheel 35 is connected below the steering mechanism 30. The first wheel 35 can be one or two. When one first wheel 35 is selected, the first wheel 35 needs to be set below the middle of the steering mechanism 30. When two first wheels 35 are provided, the two first wheels 35 are set at a predetermined distance according to needs. The number and the distance between the first wheels 35 affect the driving stability of the electric trailer. The stability of the larger distance is better than that of the smaller distance. In this application, in order to improve the stability of the electric trailer during driving, two first wheels 35 are preferably used, and the width of the two first wheels 35 is preferably 1 / 4 of the first wheel 35. The middle line of the degree corresponds to the axis of the support rod 11, and the stability is guaranteed without exceeding the width of the folding body 10 by too much. The two first wheels 35 are connected to the control mechanism 30 in a transmission manner, and the control mechanism 30 can control the two first wheels 35 to turn synchronously. A second wheel 13 is also provided at the bottom of the folding body 10. The second wheel 13 is arranged at an interval with the first wheel 35. The second wheel 13 can be one or two. The total number of the first wheel 35 and the second wheel 13 must be at least three, preferably two respectively, and the stability of four is better. It should be pointed out that when the folding body 1 When both the front and rear ends of the folding vehicle body 10 are provided with a folding pedal assembly 20 and a steering mechanism 30, the second wheel 13 needs to be arranged below the steering mechanism 30 at the rear end to achieve cargo and front and rear passenger transportation. At the same time, in order to improve the carrying capacity, a third wheel (not shown in the figure) can be arranged below one end of the folding vehicle body 10. When the third wheel is provided, the second wheel 13 needs to be a universal wheel to avoid affecting the steering, and needs to be staggered with the first wheel 35 and the second wheel 13 in the length direction to avoid being unable to be completely folded due to the volume of the wheel. The third wheel needs to be arranged at the end away from the control direction. The lever principle makes it easier to make the end of the control direction touch the ground to avoid losing control of the direction; the folding vehicle body 10 is also provided with a controller 14 and a battery 15. In this embodiment, the first wheel 35 and the second wheel 13 can both be driving wheels with hub motors, or one of the first wheel 35 and the second wheel 13 can be selected as the aforementioned driving wheel. It should be pointed out here that if the folding vehicle body 10 is provided with a third wheel and a single drive is adopted, the wheel at the end away from the control direction should not be the driving wheel to prevent the driving wheel from slipping due to insufficient friction between the driving wheel and the ground, while the four-wheel drive is not affected. ;

[0044] It should be noted that the limited rotation means that the folding pedal rod assembly 20 can only rotate within a predetermined angle range and cannot rotate outside the predetermined range.

[0045] Furthermore, a bracket connecting seat 12 is fixedly provided at the bottom end of each of the support rods 11 connected to the folding pedal rod assembly 20, and one end of the folding pedal rod assembly 20 away from the control mechanism 30 is rotatably connected to the bracket connecting seat 12, and one end of the first limiting rod 24 away from the folding pedal rod assembly 20 is rotatably connected to the bracket connecting seat 12, and an expansion limiting groove 121 is provided on the front side of one end of the bracket connecting seat 12 connected to the folding pedal rod assembly 20, and a folding limiting groove 122 is provided on the top side;

[0046] Specifically, the bottom end of each support rod 11 connected to the folding pedal rod assembly 20 is fixedly connected to a bracket connecting seat 12, and the bracket connecting seat 12 is used to connect the frame. The folding pedal rod assembly 20 is rotatably connected to the end of the bracket connecting seat 12 away from the frame. The folding pedal rod assembly 20 can rotate relative to the bracket connecting seat 12. The bottom surface of the bracket connecting seat 12 is closed, so that the side wall of the folding pedal rod assembly 20 is restricted when it contacts the bottom surface of the bracket connecting seat 12 and cannot continue to rotate. The first limit rod 24 The end away from the connection with the folding pedal rod assembly 20 is rotatably connected to the outer wall of the bracket connecting seat 12, and the first limit rod 24 is located below the folding pedal rod assembly 20. The first limit rod 24 rotates synchronously with the rotation of the folding pedal rod assembly 20. To facilitate the fixation of the folding pedal rod assembly 20, an expansion limit groove 121 is opened on the front side of one end of the bracket connecting seat 12, and a folding limit groove 122 is opened on the top side of the end, which is used to cooperate with the folding pedal rod assembly 20 to fix the folding pedal rod assembly 20.

[0047] Furthermore, each of the folding pedal rod assemblies 20 includes: a first pedal rod 21, a second pedal rod 23, and a connecting piece 26; one end of the first pedal rod 21 is rotatably connected to the bracket connecting seat 12, and one end of the second pedal rod 23 is rotatably connected to the control mechanism 30, the first pedal rod 21 and the second pedal rod 23 are arranged opposite to each other, the connecting piece 26 is located between the first pedal rod 21 and the second pedal rod 23, and the first pedal rod 21 and the second pedal rod 23 are respectively rotatably connected to the connecting piece 26, one end of the first limiting rod 24 away from the support rod 11 and one end of the second limiting rod 25 away from the control mechanism 30 are respectively rotatably connected to the connecting piece 26, and the end of the first pedal rod 21 connected to the support rod 11 is also provided with a locking assembly 27, and the locking assembly 27 is used to cooperate with the expansion limiting groove 121 and the folding limiting groove 122 to limit the rotation of the first pedal rod 21;

[0048] Specifically, the folding pedal assembly 20 includes: a first pedal 21, a second pedal 23, and a connecting member 26. One end of the first pedal 21 is rotatably connected to the bracket connecting seat 12, and the first pedal 21 can rotate relative to the bracket connecting seat 12 within a predetermined angle range. One end of the second pedal 23 is rotatably connected to the control mechanism 30, and the second pedal 23 can rotate relative to the control mechanism 30 within a predetermined angle range. The end of the first pedal 21 away from the bracket connecting seat 12 is opposite to the end of the second pedal 23 away from the control mechanism 30. The connecting member 2 6 is disposed between the opposite ends of the first pedal rod 21 and the second pedal rod 23, and the ends of the first pedal rod 21 and the second pedal rod 23 adjacent to the connecting member 26 are respectively rotatably connected to the connecting member 26. In this state, when the first pedal rod 21 or the second pedal rod 23 is subjected to force, the connecting member 26 will be driven to move, and the movements of the first pedal rod 21 and the second pedal rod 23 are not synchronized. For this purpose, a first limiting rod 24 and a second limiting rod 25 are further disposed below the first pedal rod 21 and the second pedal rod 23. The first limiting rod 24 and the second limiting rod 25 are respectively disposed at the ends of the first limiting rod 24 and the second limiting rod 25 away from the end of the bracket connecting seat 12. One end of the rod 25 away from the control mechanism 30 is rotatably connected to the connecting piece 26, and the first limiting rod 24 and the second limiting rod 25 are both spaced apart from the folding pedal rod assembly 20. The first limiting rod 24 and the second limiting rod 25 and the first pedal rod 21 and the second pedal rod 23 form a rectangular shape through the connecting piece 26, so that the first limiting rod 24 and the second limiting rod 25 are connected to the folding pedal rod assembly 20 at two points to limit the rotation of the connecting piece 26, ensure the synchronization of the first pedal rod 21 and the second pedal rod 23 and limit the rotation of the control mechanism 30. A locking assembly 27 is also slidably provided in one end of the first pedal rod 21 connected to the bracket connecting seat 12. The locking assembly 27 is used to cooperate with the expansion limit groove 121 and the folding limit groove 122 to achieve restriction of the first pedal rod 21. Since the folding pedal rod assembly 20 forms a rectangular structure with the first limit rod 24 and the second limit rod 25, when the first pedal rod 21 is restricted, the first limit rod 24, the second limit rod 25 and the second pedal rod 23 will all be unable to move, thereby achieving overall restriction with a simpler single-point restriction.

[0049] Furthermore, a sleeve 22 is fixedly sleeved outside one end of the first pedal 21 adjacent to the bracket connecting seat 12, and one end of the sleeve 22 away from the first pedal 21 is rotatably connected to the bracket connecting seat 12, and the locking assembly 27 is located in the sleeve 22;

[0050] Specifically, in order to avoid grooves on the first pedal rod 21 and affecting the strength of the first pedal rod 21, a sleeve 22 can be fixedly sleeved on the end of the first pedal rod 21 away from the second pedal rod 23. The sleeve 22 is a metal part, preferably a metal with high strength such as iron and steel. The end of the sleeve 22 away from the first pedal is rotatably connected to the bracket connecting seat 12, and the locking assembly 27 is arranged in the sleeve 22 and slides in the sleeve 22.

[0051] Furthermore, the locking assembly 27 includes: a locking pin 271, a transmission rod 272, a lever 273, and a return spring 274. The locking pin 271 is slidably disposed in the first pedal 21, and the end of the locking pin 271 passes through the first pedal 21. The locking pin 271 is adapted to the expansion limit groove 121 and the folding limit groove 122. The transmission rod 272 is located in the first pedal 21, and one end is connected to the locking pin 271. The lever 273 is disposed between the two first pedals 21. The first step rod 272 is connected to the first step rod 271 and the end of the first step rod 272 is inserted into the corresponding first step rod 21 and is detachably connected to the end of the transmission rod 272 away from the locking pin 271. The first step rod 21 is detachably provided with a first bracket 28 in the end away from the bracket connecting seat 12. The end of the transmission rod 272 away from the locking pin 271 passes through the lever 273 and is inserted into the middle of the first bracket 28. The return spring 274 is sleeved on the outer side of the transmission rod 272 and is located between the lever 273 and the first bracket 28.

[0052] Specifically, the locking pin 271 is slidably arranged in the first pedal rod 21, and the two ends of the locking pin 271 respectively pass through the first pedal rod 21. When a sleeve 22 is provided, it is preferably slidably arranged in the sleeve 22. The sliding of the locking pin 271 will be stuck in or out of the expansion limit groove 121 or the folding limit groove 122. When the locking pin 271 is stuck in the expansion limit groove 121, the cooperation between the locking pin 271 and the expansion limit groove 121 will limit the first pedal rod 21 to be in a horizontal state. At the same time, the connection between the first limit rod 24 and the connecting member 26 limits the rotation of the second pedal rod 23 and the second limit rod 25. The transmission rod 272 is located at the first pedal rod 23. The first pedal rod 21 is provided with a collar (not shown in the figure) at one end of the transmission rod 272, and the collar is used to connect with the lock pin 271. When the lock pin 271 is inserted into the collar, it can be fixed by welding or threading. A lever 273 is provided between the two first pedal rods 21. The two ends of the lever 273 are respectively inserted into the corresponding first pedal rods 21 and are threadedly connected with one end of the transmission rod 272 away from the lock pin 271. The lever 273 can slide on the first pedal rod 21 within a predetermined range. The sliding of the lever 273 will drive the transmission rod 272 to move, and the transmission rod 272 drives the lock pin 27 1 movement, thereby realizing the cooperation between the lock pin 271 and the expansion limit groove 121 or the folding limit groove 122. In order to realize that the lock pin 271 can be embedded in the expansion limit groove 121 or the folding limit groove 122 by itself, a first bracket 28 is detachably provided in the end of the first pedal 21 away from the bracket connecting seat 12, and the end of the transmission rod 272 connected to the lever 273 passes through the lever 273 and is inserted into the first bracket 28 and can slide in the first bracket 28. At the same time, a return spring 274 is also sleeved on the outer side of the transmission rod 272. The return spring 274 is located between the lever 273 and the first bracket 28. When the lever 273 is engaged, the return spring 274 is engaged with the first bracket 28. When the rod 273 is driven to slide in the direction of the first bracket 28, the lever 273 drives the transmission rod 272, driving the locking pin 271 to disengage from the groove. When the lever 273 slides, it also squeezes the return spring 274. At this time, the first pedal 21 can be rotated. When the first pedal 21 is rotated to a predetermined position, the force applied to the lever 273 can be canceled. At this time, the return spring 274 loses the squeezing force of the lever 273, and slides against the lever 273 under its own restoring force. The lever 273 pushes the transmission rod 272, driving the locking pin 271 to embed into the corresponding groove, thereby achieving a self-locking effect.

[0053] Furthermore, a second bracket 29 is provided in one end of the first pedal 21 adjacent to the bracket connecting seat 12. The second bracket 29 is sleeved on the outer side of the transmission rod 272. The transmission rod 272 can slide relative to the second bracket 29.

The transmission rod 272 is suspended at a predetermined height through the support of the second bracket 29 and the first bracket 28, and it is ensured that the transmission rod 272 is always in a horizontal state, while preventing the transmission rod 272 from swinging. Moreover, since the first bracket 28 and the second bracket 29 are arranged inside the first pedal 21, the first bracket 28 and the second bracket 29 also play the role of filling the first pedal 21, thereby further improving the bearing strength of the first pedal 21.

[0055] Furthermore, in the present embodiment, the first pedal bar 21 and the second pedal bar 23 are respectively provided with a pedal 212, and a hole 213 is provided in the middle of the pedal 212 arranged on the first pedal bar 21; specifically, to facilitate standing riding, pedals 212 are respectively provided on the first pedal bar 21 and the second pedal bar 23, and the user can directly stand on the pedal 212 to ride, wherein a hole 213 is provided in the middle of the pedal 212 located on the first pedal bar 21, and the hole 213 corresponds to the lever 273, and when in use, the hand can be inserted through the hole 213, thereby driving the lever 273 to move.

[0056] Furthermore, in the present embodiment, mutually meshing teeth 211 are respectively provided at opposite ends of the first pedal 21 and the second pedal 23. To achieve synchronous rotation of the first pedal 21 and the second pedal 23 when they are folded, mutually meshing teeth 211 are respectively provided at opposite ends of the first pedal 21 and the second pedal 23. With the cooperation of the teeth 211, synchronous rotation of the first pedal 21 and the second pedal 23 is achieved.

The two first wheels 35 can rotate in situ relative to the connecting rod 33. A horizontally extending wheel swing arm 351 is provided on a side of each first wheel 35 away from the folding body 10. The two first wheels 35 are rotatably connected to the two ends of the connecting rod assembly 34 through the wheel swing arm 351. When the direction rod assembly 31 rotates, it drives the connecting rod assembly 34 to move, and the connecting rod assembly 34 drives the first wheels 35 rotating at its two ends to rotate synchronously in the same direction, thereby realizing the direction control of the first wheels 35.

[0059] Furthermore, the two ends of the connecting rod 33 facing the folding body 10 are respectively provided with connecting ears 331, and the end of the folding pedal rod assembly 20 away from the support rod 11 is rotatably connected to the connecting ears 331;

[0060] Specifically, connecting ears 331 extending outward are respectively provided at both ends of the connecting rod 33 facing the folding body 10, and the end of the first pedal bar 21 away from the connecting ear 331 is rotatably connected. The connecting ear 331 extending outward can stagger the connection point between the first pedal bar 21 and the connecting rod 33 and the connection point between the first wheel 35 and the connecting rod 33, thereby facilitating the unfolding of the first pedal bar 21 with less effort; in order to further improve the bearing capacity of the first pedal bar 21, the bottom of the connecting ear 331 is closed. When the first pedal bar 21 is rotated downward by a predetermined angle relative to the connecting ear 331, it is restricted by the structure of the connecting ear 331 and cannot continue to rotate, thereby supporting the first pedal bar 21, thereby improving the bearing capacity of the first pedal bar 21.

[0061] A foot brake (not shown) is provided on one end of the connecting rod 33, and the foot brake is connected to the first wheel 35 and / or the second wheel 13 for braking.

[0063] Specifically, the direction rod assembly 31 passes through one end of the connecting rod 33 and is fixedly connected to the direction link 342. The rotation of the direction rod assembly 31 will drive the end of the direction link 342 away from the direction rod assembly 31 to rotate around the direction rod assembly 31. A sliding groove is provided at the end of the direction link 342 away from the direction rod assembly 31. At the same time, a sliding shaft is provided in the middle of the direction transmission rod 341. The direction transmission rod 341 is movably connected to the direction link 342 through the sliding shaft. The two ends of the direction transmission rod 341 are respectively rotatably connected to the corresponding wheel swing arms 351. When the direction link 342 rotates, it will drive the direction transmission rod 341 to move left and right. The direction transmission rod 341 then drives the two first wheels 35 to rotate synchronously, wherein the sliding groove is used to enable the sliding shaft to be displaced when the direction link 342 rotates to avoid movement conflicts.

[0064] Further, in the present embodiment, the direction rod assembly 31 comprises: an outer rod 311, an inner rod 312, and a turning rod 313; the turning rod 313 is disposed through the middle portion 33 of the connecting rod 33, the top of the turning rod 313 is rotatably connected to the outer rod 311, the inner rod 312 is slidably disposed in the outer rod 311, the top of the inner rod 312 is connected to a direction handle 314, and a limit assembly 32 is disposed in one end of the outer rod 311 connected to the turning rod 313, and the limit assembly 32 is used to limit the rotation of the outer rod 311 relative to the turning rod 313;

[0065] Specifically, the inner rod 312 is movably arranged in the outer rod 311, the turning rod 313 is penetrated in the middle of the connecting rod 33, the turning rod 313 can rotate relative to the connecting rod 33, and the direction connecting rod 342 is fixedly connected to the bottom end of the turning rod 313, the top of the turning rod 313 is rotatably connected to the bottom end of the outer rod 311, and the outer rod 311 can rotate vertically relative to the turning rod 313 to change the angle of the direction rod assembly 31 when towing is required, so as to facilitate towing; in order to limit the free rotation of the outer rod 311 relative to the turning rod 313, a The limit position assembly 32 includes: a folding limit latch 321 and a folding limit restoring spring 324. The folding limit latch 321 is slidably arranged in one end of the outer rod 311 connected to the turning rod 313. The folding limit latch 321 can slide up and down in the outer rod 311. A latch head 322 is provided on the top of the folding limit latch 321. The folding limit restoring spring 324 is sleeved on the outside of one end of the folding limit latch 321.

When the inner rod 312 is retracted into the outer rod 311, it will contact the folding head 322 and squeeze the end of the folding limit pin 321 out of the outer rod 311. At the same time, the folding limit restoring spring 324 is squeezed by the folding head 322. After the folding limit pin 321 is squeezed out of the outer rod 311, if the outer rod 311 and the folding rod 313 are in a vertical state, it will be directly inserted into the folding hole, so that the outer rod 311 and the folding rod 313 are fixed to each other through the folding limit pin 321. When the rod 311 and the turning rod 313 are fixed, it is only necessary to extend the inner rod 312 out of the outer rod 311. At this time, the pin loses the squeezing of the inner rod 312, and the folding limit restoring spring 324 generates a restoring force to lift the folding limit pin 321 and retract it into the end of the outer rod 311. At this time, the fixation between the outer rod 311 and the turning rod 313 is released.

Folding grooves 315 are respectively provided on both sides of the direction handle 314, and a grip rod 316 is rotatably connected to one end of the folding sleeve. The grip rod 316 can be stored in the folding groove 315 when not in use, and the grip rod 316 can be rotated to be horizontal when needed. One of the two grip rods 316 can be set to rotate, that is, the grip rod 316 can rotate in situ on the direction handle 314, just like the throttle grip of an electric bicycle, and the rotation speed of the external electric wheel can be controlled by the rotation angle; a handle limit pin 317 is also provided on the top surface of the end where the folding groove 315 and the grip rod 316 are connected. The handlebar limit pin 317 is a pin structure with a spring inside. At the same time, a limit hole (not shown in the figure) adapted to the handlebar limit pin 317 is provided on the end where the handlebar 316 is connected to the folding groove 315, which is used to limit the handlebar 316 when the handlebar 316 is in a horizontal state or stored relative to the direction handle 314; a plurality of control buttons 318 are also provided on the direction handle 314, and the control buttons 318 include but are not limited to forward / reverse buttons, driving / towing switching buttons, trailer power-assist speed control buttons, headlight switch buttons, horn buttons, turn signal control buttons, etc. For details, reference can be made to the button design of the electric bicycle in the prior art. A display device 319 for displaying power and speed is also provided on the direction handle 314, and the display device 319 and the control buttons 318 are respectively electrically connected to the controller 14.

[0068] Furthermore, a telescopic latch 3121 is provided inside the inner rod 312, a plurality of telescopic holes 3111 adapted to the telescopic latch 3121 are provided on the outer rod 311, and a telescopic button 3141 for controlling the extension and retraction of the telescopic holes 3111 is also provided on the bottom inner wall of the direction handle 314;

A telescopic button 3141 is also provided on the direction handle 314. The telescopic pin 3121 will pass through the inner rod 312 and insert into the telescopic hole 3111 on the outer rod 311 according to the pressing of the telescopic button 3141 to restrict the inner rod 312 and prevent the inner rod 312 from moving freely in the outer rod 311. The specific structure between the telescopic button 3141 and the telescopic pin 3121 adopts the existing technology, and can refer to the pull rod limiting structure of the existing luggage case or the structure disclosed in Chinese patent CN201821724858.2, so it will not be described in detail here.

[0070] It should be pointed out that in order to improve the comfort of use of the trailer, a foldable seat plate can be provided above the front end of the foldable body 10.

At the same time, a pedal 212 can be fixedly provided between the two first pedal bars 21. The pedal 212 is folded as the first pedal bar 21 is folded, so that people can stand or put their feet.

[0071] It should be noted that when the folding vehicle body adopts a gathering type vehicle body, in order to avoid affecting the folding of the folding vehicle body, the synchronization rod 25, the connecting rod 33 and the connecting rod assembly 34 need to be a foldable structure.

[0072] In summary, the utility model realizes the overall linkage of the folding pedal rod assembly by setting the first limit rod and the second limit rod, and the overall limitation of the folding pedal rod assembly can be realized by only fixing one position at random, and the two pedals can be folded relative to each other, and the first wheel will not rotate therewith when folding. The design is reasonable, the structure is simpler, the cost is further reduced, the assembly is also simple, and the production efficiency is effectively improved.
