[0066] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0067] Reference is made to the accompanying Figure 1 - the accompanying Figure 15 The present application provides a unicycle, which comprises a front wheel assembly 10 composed of two front wheels 101, a transmission structure 20, a head assembly 30, a shock-absorbing assembly and a drive assembly 60.

[0068] The head assembly 30 comprises a telescopic head pipe 301, and left and right handlebars 303 and 304 foldably connected to the head pipe 301.

[0069] The transmission structure 20 is provided at one end with a driving shaft 201 and at the other end with a driven shaft, and the drive assembly 60 is foldably connected to the driving shaft 201; the front wheel assembly 10 is connected to the driven shaft and the transmission structure 20 is partially located between the two front wheels 101.

[0070] The shock-absorbing assembly is movably connected to the transmission structure 20, and is located at the front side of the unicycle, and the head pipe 301 is foldably connected to the shock-absorbing assembly.

[0071] When folded, the left handle 303 and the right handle 304 are folded to be parallel to the head tube 301, the head tube 301 is folded to the rear side of the unicycle around the connecting end, and the driving assembly 60 is folded to the side of the front wheel assembly 10, so that the whole vehicle forms a folding structure in which the head assembly 30 and the shock absorbing assembly are sequentially arranged around the outer periphery of the front wheel assembly 10, and the driving assembly 60 is arranged to the side of the front wheel assembly 10.

[0072] In the embodiment, the transmission structure 20 is provided with a driving shaft 201 and a driven shaft, the driving shaft 201 transmits power to the driven shaft through the inside of the transmission structure 20, and the driven shaft can drive the front wheel 101 to move. The transmission structure 20 is movably connected with the shock absorbing assembly, and when the front wheel 101 vibrates, the vibration can be buffered by the shock absorbing assembly, thereby improving the riding comfort of the bicycle. The driving assembly 60 refers to the left crank 601 and the right crank. Unlike the conventional round riding crank, the crank of the present application is a riding mode of up and down pedaling. When folded, the left crank 601 is folded to the left side of the left front wheel 101, and the right crank is folded to the right side of the right front wheel 101, that is, the driving assembly 60 is folded to the side of the front wheel assembly 10. Different from the normal pedal which is transversely arranged outside the crank, the left pedal 6012 and the right pedal 6022 are parallel to the front wheel 101 after folding, and the volume is smaller. The head assembly 30 refers to the handlebar of the bicycle, and the handlebar is connected with the head tube 301. The head tube 301 is telescopic, as shown in Figure 1 and Figure 11 The handlebar can be arranged in a structure parallel to the head tube 301 after folding, or can be arranged in a structure perpendicular to the head tube 301 after folding. The former can be closely attached to the front wheel 101 after folding. The latter forms an L shape after folding, and the head tube 301 and the handlebar are closely attached and arranged around the front wheel 101. It is worth mentioning that in the unfolded state, the pedals are located at the rear side of the wheels, and one end of the grip of the handlebar is slightly inclined forward of the head. When the whole vehicle is relatively small, the user naturally stretches his hand to the position of the control grip, which is beneficial to hand control and power output. The shock absorbing assembly is located at the rear side of the wheels. At this time, when the user rides, the center of gravity is located at the middle of the wheels. Combined with the double wheel structure, the center of gravity is better controlled, the riding is more comfortable, and it is more in line with ergonomics.

[0073] In summary, the unicycle of the present application has the following advantages. When folded, the left handle 303 and the right handle 304 are folded to be parallel to the head tube 301, the head tube 301 is folded to the rear side of the unicycle around the connecting end, and the driving assembly 60 is folded to the side of the front wheel assembly 10, so that the whole vehicle forms a folding structure in which the head assembly 30 and the shock absorbing assembly are sequentially arranged around the outer periphery of the front wheel assembly 10, and the driving assembly 60 is arranged to the side of the front wheel assembly 10, which has the characteristics of small occupied space after folding, easy to carry and store.

[0075] When unfolded, the top end of the sliding sleeve 305 is sleeved on the head tube 301, and the bottom end of the sliding sleeve 305 is sleeved on the hinged column 405;

[0076] When folded, the sliding sleeve 305 is separated from the hinged column 405 and is sleeved on the head tube 301.

[0077] In this embodiment, the outer wall of the bottom end of the head tube 301 is provided with external threads, and the inner wall of the sliding sleeve 305 is provided with internal threads that are screwed with the external threads. The user can drive the bottom end of the sliding sleeve 305 to slide along the head tube 301 by rotating the sliding sleeve 305, and the stable connection between the sliding sleeve 305 and the hinged column 405 is ensured by the self-locking property of the threads, so as to avoid the sliding sleeve 305 from being easily detached, thereby improving the safety of the unicycle.

[0078] Further, the top end of the hinged column 405 is provided with a first connector 4051, the bottom end of the head tube 301 is matched with a second connector 3011, a through slot 40511 is formed in the first connector 4051, and a latch 40512 is connected between the inner walls of the through slot 40511. The second connector 3011 extends into the through slot 40511 and is hinged to the latch 40512.

The aforementioned second shock absorber link includes a second left shock absorber link and a second right shock absorber link. One end of the second left shock absorber link is connected to the left shock absorber bracket via a bearing 70, and the other end is connected to the transmission structure 20 via a bearing 70. Symmetrically, one end of the second right shock absorber link is connected to the right shock absorber bracket via a bearing 70, and the other end is connected to the transmission structure 20 via a bearing 70, forming a double-arm support structure for the second left and second right shock absorber links. This results in more even force distribution during vibration, improving shock absorber stability.

[0090] In one embodiment, the left support of the shock absorber is provided with a first lower limit portion, the right support of the shock absorber is provided with a second lower limit portion, and the drive assembly 60 includes a left crank 601 and a right crank.

[0091] The left crank 601 drives the left end of the drive shaft 201 through the first ratchet connection, and the right crank drives the right end of the drive shaft 201 through the second ratchet connection.

[0092] The first lower limit portion is located at a first position between the driven shaft and the left crank 601, and is used to limit the lower limit position of the rotation of the left crank 601; the second lower limit portion is located at a second position between the driven shaft and the right crank, and is used to limit the lower limit position of the rotation of the right crank.

[0093] In this embodiment, unlike the traditional unicycle bicycle, the left and right cranks of the traditional pedal bicycle continuously complete a circular motion during use, but the left crank 601 and the right crank of the above-mentioned unicycle bicycle are alternately reciprocating curve motion, so that during the downward movement of the crank of the bicycle, in order to prevent the crank from continuing to make a circular motion, the movement amplitude is too large to make the user difficult to balance, so it is necessary to set a lower limit portion to limit it. When the user needs to rest, the lower limit portion can also support the crank. Specifically, the two ends of the drive shaft 201 are connected to the left crank 601 and the right crank, respectively, and the power of the two cranks is transmitted to the transmission structure 20 connected in the middle, and then drives the left front wheel 101 and the right front wheel 101 to rotate. The front ends of the left crank 601 and the right crank are connected to the two sides of the transmission structure 20 at positions close to the upper part of the upper end of the transmission structure 20, and the connecting shaft is located at a position close to the lower part of the upper end of the transmission structure 20. Figure 9 Taking the left crank 601 and the first lower limit portion as an example, the right crank and the second lower limit portion are similar. When the left crank 601 abuts against the first lower limit portion, the left crank 601 is located at its lower limit position of rotation, and at this time the first lower limit portion is close to the middle part of the left crank 601 as much as possible, avoiding the situation that the force arm is too long when the left crank 601 is under stress, causing the pressure on the connection between the first lower limit portion or the left crank 601 and the transmission structure 20 to be too large, and if the material strength of the left crank 601 or the transmission structure 20 is not enough, it is easy to break. In addition, since the first lower limit portion is arranged on the left bracket of the shock absorber, and the second lower limit portion is arranged on the right bracket of the shock absorber, a buffering effect can be formed when the left crank 601 abuts against the first lower limit portion, and a buffering effect can be formed when the right crank abuts against the second lower limit portion, thereby protecting the left crank 601.

[0094] In one embodiment, the drive assembly 60 further comprises a first upper limit portion 202 and a second upper limit portion 203; the first upper limit portion 202 is arranged on the left side of the transmission structure 20 close to the left end of the drive shaft 201, and is used to limit the upper limit position of the rotation of the left crank 601;

[0095] The second upper limit part 203 is arranged on the right side of the transmission structure 20 near the right end of the driving shaft 201, and is used for limiting the upper limit position of the rotation of the right crank.

[0096] In the embodiment, the second upper limit part 203 cooperates with the first upper limit part 202, and the second lower limit part cooperates with the first lower limit part. In addition, the front end of the left crank 601 is provided with a first connecting sleeve 60121, the first connecting sleeve 60121 is sleeved on the first ratchet wheel 605, and a first limiting block is arranged on the outer wall of the first connecting sleeve 60121;

[0097] The first upper limit part 202 comprises a first torsion spring 2021 and a first limiting claw 2022, the first limiting claw 2022 has a protruding first claw end, the first limiting claw 2022 is rotatably sleeved on the driving mechanism, one end of the first torsion spring 2021 is clamped with the first limiting claw 2022, and the other end is clamped on the driving mechanism, so as to limit the first claw end to the limiting position of the first limiting block, and rotating the first limiting claw 2022 can make the first claw end deviate from the limiting position of the first limiting block;

[0098] The front end of the right crank 602 is provided with a second connecting sleeve 60221, the second connecting sleeve 60221 is sleeved on the second ratchet wheel 606, and a second limiting block is arranged on the outer wall of the second connecting sleeve 60221;

[0099] The second upper limit part 203 comprises a second torsion spring 2031 and a second limiting claw 2032, the second limiting claw 2032 has a protruding second claw end, the second limiting claw 2032 is rotatably sleeved on the driving mechanism, one end of the second torsion spring 2031 is clamped with the second limiting claw 2032, and the other end is clamped on the driving mechanism, so as to limit the second claw end to the limiting position of the second limiting block, and rotating the second limiting claw 2032 can make the second claw end deviate from the limiting position of the second limiting block;

[0100] The left end of the driving shaft 201 is sleeved with a third torsion spring, one end of the third torsion spring is clamped with the first connecting sleeve 60121, and the other end is clamped with the driving mechanism;

[0101] The right end of the driving shaft 201 is sleeved with a fourth torsion spring, one end of the fourth torsion spring is clamped with the second connecting sleeve 60221, and the other end is clamped with the driving mechanism.

[0102] Taking the left crank 601 as an example, the right crank 602 is similar. The front end of the left crank 601, that is, the end where the left crank 601 connects to the drive shaft 201, is the first connecting sleeve 60121. The first connecting sleeve 60121 is a hollow tube that fits onto the first ratchet 605. The inner wall of the first connecting sleeve 60121 has a toothed structure that can cooperate with the first toothed sleeve 6054. The first claw end of the first limiting pawl 2022 abuts against the outer surface of the first connecting sleeve 60121. As the first connecting sleeve 60121 rotates upward, the first limiting block abuts against the first claw end of the first limiting pawl 2022. The first limiting pawl 2022 limits the first limiting block. (Refer to...) Figure 1 , Figure 2 and Figure 3 One end of the first torsion spring 2021 is engaged with the first limiting pawl 2022, and the other end is engaged with the housing of the transmission structure 20. When the first limiting pawl 2022 is rotated, it causes the first torsion spring 2021 to twist and generate elastic potential energy. After the first limiting pawl 2022 is released, the first torsion spring 2021 causes the first limiting pawl 2022 to return to its original position. When it is necessary to fold the bicycle, the first limiting pawl 2022 can be rotated upward so that the first pawl end is away from the rotation path of the first limiting block, so that it can no longer block the first limiting block. Then the left crank 601 can rotate upward and forward without obstruction and fold to the side of the left front wheel 101. Regarding the riding method of this unicycle, let's take an example. Assuming the origin is on the drive shaft and the X-axis points forward, the lower limits of the left and right cranks can be set at angles between 180 and 240 degrees to the horizontal. When riding, the user pedals within a range of approximately 100 degrees, such as between 135 and 225 degrees, ensuring they are always pedaling at the most efficient angle. The vertical reset also saves a lot of idle travel compared to a 360-degree circular motion. In this case, the cranks can be made longer than those on a regular bicycle. According to the lever principle, a longer lever arm requires less effort. Regular bicycles, because the cranks work in circles, and to prevent them from hitting the ground, limit their length. Furthermore, this vertical pedaling method is more suitable for standing riding, thus fully utilizing the rider's own weight, making riding easier and more ergonomic. Combining these three points, this pedaling system is more than 50% more efficient than a regular bicycle.

[0103] In one embodiment, the rear end of the left crank 601 is provided with a first connecting tube 6011. The first connecting tube 6011 has a first interface 60111 and a second interface 60112 with their axes perpendicular to each other. The first interface 60111 is sleeved on the left crank 601, and the second interface 60112 is connected to the left pedal 6012. The left pedal 6012 can be folded around the rear end of the left crank 601.

[0104] The rear end of the right crank 602 is provided with a second connecting pipe 6021, the second connecting pipe 6021 has a third interface 60211 and a fourth interface 60212 which are perpendicular to each other, the third interface 60211 is sleeved with the right crank 602, and the fourth interface 60212 is connected with a right pedal 6022, the right pedal 6022 can be folded around the rear end of the right crank 602;

[0105] The first connecting pipe 6011 further comprises a first anti-rotation interface 60113, the left crank 601 further comprises a first anti-rotation assembly 6013, the first anti-rotation assembly 6013 is detachably connected with the left crank 601 through the first anti-rotation interface 60113 and limits the first connecting pipe 6011;

[0106] The second connecting pipe 6021 further comprises a second anti-rotation interface 60213, the right crank 602 further comprises a second anti-rotation assembly 6023, the second anti-rotation assembly 6023 is detachably connected with the right crank 602 through the second anti-rotation interface 60213 and limits the second connecting pipe 6021.

[0107] In the embodiment, reference is made to the accompanying drawings Figure 10For example, the first connecting pipe 6011 is a "T" or "L" type connecting pipe, the two end pipe orifice axes of the first connecting pipe 6011 are perpendicular to each other, one end of the first connecting pipe 6011 is sleeved on the rear end of the left crank 601, the first connecting pipe 6011 can rotate about the axis of the rear end of the left crank 601, and the other end of the first connecting pipe 6011 is connected to one end of the left pedal 6012, and the left pedal 6012 can rotate about the axis of the rear end of the left crank 601. When the above-mentioned folding bicycle is folded, rotating the first connecting pipe 6011 upward by 90° can make the left pedal 6012 parallelly adhere to the left side of the left front wheel 101; in addition, in order to form support for the feet of the user when the left pedal 6012 is used, a mechanism for preventing the first connecting pipe 6011 from rotating is further arranged on the first connecting pipe 6011. The first anti-rotation assembly 6013 is one part or a combination of several parts with a circumferential limiting structure, and is composed of a spring sheet 60131, a first anti-rotation stop sheet 60132 and a screw 60133, wherein the inner side of the first anti-rotation stop sheet 60132 is provided with an inwardly protruding quadrangular protrusion, and the end face of the end of the left crank 601 is provided with a quadrangular groove, the first anti-rotation stop sheet 60132 is clamped by the quadrangular protrusion and the quadrangular groove and is fixed to the end of the left crank 601 by the screw 60133, so that the first anti-rotation stop sheet 60132 cannot rotate circumferentially, and at this time, the spring sheet 60131 is clamped between the first anti-rotation stop sheet 60132 and the first connecting pipe 6011 to increase the rotating friction of the first connecting pipe 6011, that is, only when the left pedal 6012 is pulled very hard, the left pedal 6012 can rotate. The end of the first connecting pipe 6011 and the left crank 601 can also be provided with clamping blocks, that is, the inner side wall of the first connecting pipe 6011 and the outer side wall of the end of the left crank 601 are provided with clamping blocks matched with each other, so as to limit the left pedal 6012 when it is folded outward to a position parallel to the horizontal plane, and the second connecting pipe 6021 is similar to the first connecting pipe 6011 and will not be repeated here.

[0114] The first limiting screw 3033 passes through the first opening 30311 from one side of the first limiting ring 3032 and is fixed to the other side of the first limiting ring 3032, so that the first limiting ring 3032 is sleeved on the third joint 3031; the second limiting screw 3043 passes through the second opening 30411 from one side of the second limiting ring 3042 and is fixed to the other side of the second limiting ring 3042, so that the second limiting ring 3042 is sleeved on the fourth joint 3041;

[0115] When the left handle 303 and the right handle 304 are both in the unfolded state position, the first opening 30311 corresponds to the first limiting gap 30211, the first limiting ring 3032 is clamped outside the first connecting port 3021, and the first limiting screw 3033 is clamped on the first limiting gap 30211; the second opening 30411 corresponds to the third limiting gap 30221, the second limiting ring 3042 is clamped outside the second connecting port 3022, and the second limiting screw 3043 is clamped on the third limiting gap 30221; when the left handle 303 and the right handle 304 are both in the folded state position, the first opening 30311 corresponds to the second limiting gap 30212, the first limiting ring 3032 is clamped outside the first connecting port 3021, and the first limiting screw 3033 is clamped on the second limiting gap 30212; the second opening 30411 corresponds to the fourth limiting gap 30222, the second limiting ring 3042 is clamped outside the second connecting port 3022, and the second limiting screw 3043 is clamped on the fourth limiting gap 30222.

[0116] The first opening 30311 is a pair of openings with the axis of the third joint 3031 as the symmetry axis, and the first limiting screw 3033 can slide left and right in the first opening 30311, which forms a sliding groove for the first limiting screw 3033. The first limiting screw 3033 can be moved left and right in the first opening 30311 by an external force, such as a user's hand. When it is necessary to fix the left handle 303 in the use state position, the third joint 3031 of the left handle 303 is inserted into the first connecting port 3021 in the use state position, at this time, the side of the first opening 30311 close to the first limiting gap 30211 is aligned with the first limiting gap 30211, and then the first limiting screw 3033 is pulled onto the first limiting gap 30211 for clamping, so that the left handle 303 is fixed. It is worth mentioning that the first limiting screw 3033 can be connected to the first limiting gap 30211 by interference fit, and can also be connected by spring as described in the subsequent embodiments. When disassembling, the first limiting screw 3033 is pulled out of the first limiting gap 30211, and the left handle 303 can be rotated and stored. The fixing of the left handle 303 in the folded state position is similar to the above principle and will not be repeated; similarly, the fixing and disassembly principles of the right handle 304 in the use state position and the folded state position are similar to those of the left handle 303 and will not be repeated. In addition, the first limiting gap 30211 and the second limiting gap 30212 can be arranged adjacent to each other, i.e. the second limiting gap 30212 is next to the first limiting gap 30211, and the specific arrangement can be as shown in the subsequent embodiments. Figures 11-12As shown, in this case, the use state position of the left handle 303 is slightly inclined to the front of the vehicle, the user's hand is stretched forward to control the handlebar, and the whole vehicle can be made smaller, and the inclination effect can be as shown in the attached Figure 6 As shown.

[0117] In one embodiment, the left handle 303 further comprises a third spring 3034, and the right handle 304 further comprises a fourth spring 3044, wherein

When the third spring 3034 is connected to the first limiting hook 30312 at one end and to the first limiting screw 3033 at the other end, the third spring 3034 is in a stretched state and can always generate a spring force to pull the first limiting screw 3033 towards the first limiting hook 30312. Since the third joint 3031 is inserted into the first connecting port 3021 for connection, when connected, the first limiting hook 30312 is located inside the first limiting notch 30211, that is, a pulling force is always generated to clamp the first limiting screw 3033 on the first limiting notch 30211, preventing the first limiting screw 3033 from being separated from the first limiting notch 30211. The connection of the first limiting screw 3033 to the second limiting notch 30212 is similar to the above and will not be repeated. The left handle 303 is taken as an example for illustration: the first opening 30311 is a pair of openings with the axis of the third joint 3031 as the symmetry axis, and the first limiting screw 3033 can slide left and right in the first opening 30311, that is, the first opening 30311 forms a sliding groove for the first limiting screw 3033, and the first limiting screw 3033 can be moved left and right in the first opening 30311 by external force, for example, the user can use his hand to move the first limiting screw 3033 left and right in the first opening 30311, so that the first limiting screw 3033 can slide left and right in the first opening 30311. When it is necessary to fix the left handle 303 in the use state position, only need to insert the third joint 3031 of the left handle 303 into the first connecting port 3021 in the use state position, at this time, the side of the first opening 30311 close to the first limiting notch 30211 is aligned with the first limiting notch 30211, and then the first limiting screw 3033 is moved to the first limiting notch 30211 for clamping, so that the left handle 303 is fixed. It is worth mentioning that the first limiting screw 3033 can be connected to the first limiting notch 30211 by interference fit, and when disassembled, only need to pull out the first limiting screw 3033 from the first limiting notch 30211, and the left handle 303 can be rotated and stored. The fixing of the left handle 303 in the folding state position is similar to the above principle and will not be repeated; similarly, the fixing and disassembly principles of the right handle 304 in the use state position and the folding state position are similar to those of the left handle 303 and will not be repeated. In addition, the first limiting notch 30211 and the second limiting notch 30212 can be arranged adjacent to each other, that is, the second limiting notch 30212 is beside the first limiting notch 30211, and the specific arrangement can be as shown in the following figure: Figure 13As shown, in this case, the use state position of the left handle 303 is slightly inclined to the front of the vehicle, the user's hand is stretched forward to control the handlebar, and the whole vehicle can be made smaller, and the inclination effect can be as shown in the attached Figure 6 As shown.
