[0030] A folding bicycle is a convenient means of transportation for short-distance travel. When not in use, the occupied space of the folding bicycle can be reduced by folding, which is convenient for storage. However, most of the current folding bicycles usually have complex folding mechanisms, heavy weights, and still occupy a relatively large space after folding. For users with mobility difficulties, the effect of folding is minimal, and thus a folding bicycle is proposed.

[0031] In this embodiment, as Figure 1 shown, the folding bicycle may include a handlebar assembly 01, a front bicycle assembly 02, a rear bicycle assembly 03, and a seat assembly 04;

[0032] The front vehicle assembly 02 may include a front frame 21 and front wheels 22. The front frame 21 may include a cross beam frame 211, a front riser 212, a rear riser 213, and a connecting plate 214. The front riser 212, the cross beam frame 211, and the rear riser 213 may be fixedly connected in sequence. The connecting plate 214 may be fixedly connected to one end of the cross beam frame 211 close to the rear riser 213. The way of integral fixed connection can improve the strength of the front frame 21. The handlebar assembly 01 may be hinged to the front riser 212, and the user can operate the handlebar assembly 01 to achieve the folding function of the folding bike. The front wheels 22 may be movably connected to the front riser 212. The front wheels 22 can rotate around the central axis of the front wheels 22 to enable the folding bike to travel. The handlebar assembly 01 can drive the front wheels 22 to rotate around the central axis of the front riser 212 through the front riser 212, and the user can operate the handlebar assembly 01 to make the folding bike turn or go straight according to their intention.

[0033] The rear vehicle assembly 03 may include a triangular frame 31 and two rear wheels 32. One end of the triangular frame 31 may be hinged to the connecting plate 214. When the user does not need to drive the folding bike and wants to store the folding bike, the triangular frame 31 can be folded, thereby reducing the occupied space of the folding bike and achieving the effect of being convenient to carry; at the same time, the triangular frame 31 is designed in a triangular shape, and this design method can minimize the weight as much as possible while ensuring the strength. The two rear wheels 32 may be movably connected to the other two ends of the triangular frame 31 respectively. The rear wheels 32 can rotate around their own central axes, and the two rear wheels 32 and the front wheels 22 contact the ground simultaneously during driving, so that the folding bike can travel smoothly.

[0034] The seat assembly 04 may be detachably connected to the rear riser 213. When the user drives the folding bike, they can sit on the seat assembly 04, which can effectively reduce the fatigue caused by driving; when the user needs to store or assemble the folding bike, the detachable connection method can facilitate the disassembly and assembly of the seat assembly 04 with the rear riser 213, improving the convenience of user use.

[0035] Such as Figure 2 、 Figure 3 、 Figure 4As shown, the folding bike can include a folded state. The folded state can include that the minimum angle between the central axis of the handlebar assembly 01 and the central axis of the crossbar frame 211 is less than a first set angle (the first set angle can be 15°), and the minimum angle between the set plane of the tripod 31 (the set plane can be the plane where the hinge between the tripod 31 and the connecting plate 214 and the rotation center lines of the two rear wheels 32 are located) and the central axis of the crossbar frame 211 is less than a second set angle (the second set angle can be 15°), and the shortest distance between the rotation center of the rear wheel 32 and the rotation center of the front wheel 22 is less than a first set distance (the first set distance can be half of the radius of the rear wheel 32). When the folding bike is folded, the central axis of the handlebar assembly 01 and the central axis of the crossbar frame 211 tend to be parallel, the distance between the side of the tripod 31 away from the connecting plate 214 and the crossbar frame 211 is small, and the front wheel 22 is located within the space surrounded by the two rear wheels 32, so that the folding bike is more compact, occupies as little space as possible, and achieves the effect of being easy to carry.

[0036] In some embodiments, as Figure 1 , Figure 2 shown, the handlebar assembly 01 can include a handle 11 and a handlebar stem 12. One end of the handlebar stem 12 can be hinged to the front riser 212, and the user can move the handlebar stem 12 towards the crossbar frame 211 to reduce the occupied space of the folding bike. The other end of the handlebar stem 12 can be detachably connected to the handle 11, and the user can operate the handle 11 to make the folding bike go straight or turn according to his own intention.

[0037] The folded state can also include that the minimum angle between the central axis of the handlebar stem 12 and the central axis of the crossbar frame 211 is less than a third set angle (the third set angle can be 15°), so that the end of the handlebar stem 12 away from the front riser 212 is as close as possible to the crossbar frame 211, thereby reducing the occupied space after the folding bike is folded.

[0038] In some embodiments, as Figure 1 , Figure 2 , Figure 3 shown, the handlebar assembly 01 can also include a first connecting part 13. The first connecting part 13 is detachably connected to the handle 11. When the first connecting part 13 is damaged, the first connecting part 13 can be quickly replaced.

[0039] The front vehicle assembly 02 can also include a second connecting part 26. The second connecting part 26 is detachably connected to the crossbar frame 211. When the second connecting part 26 is damaged, the second connecting part 26 can be quickly replaced.

[0040] The folded state may further include a detachable connection between the first connecting portion 13 and the second connecting portion 26. The detachable connection may be a snap connection or a magnetic attraction connection, and preferably a magnetic attraction connection, which can reduce the operation steps when the user folds. When the user moves the handlebar 12 towards the cross beam frame 211 until the first connecting portion 13 is detachably connected to the second connecting portion 26, the relative positions of the first connecting portion 13 and the second connecting portion 26 can be fixed, facilitating the storage of the folding bicycle.

[0041] In some embodiments, as Figure 1 shown, the tripod 31 may include a first inclined column 311, a second inclined column 312, and a first support column 313. One end of the first inclined column 311 may be hinged to the connecting plate 214, and the other end extends away from the front wheel 22. One rear wheel 32 may be movably connected to the end of the first inclined column 311 away from the front wheel 22. One end of the second inclined column 312 may be hinged to the connecting plate 214, and the other end may extend away from the front wheel 22. The other rear wheel 32 is movably connected to the end of the second inclined column 312 away from the front wheel 22. One end of the first support column 313 is fixedly connected to the first inclined column 311, and the other end is fixedly connected to the second inclined column 312. The first inclined column 311, the second inclined column 312, and the first support column 313 enclose a triangular structure, which can reduce the weight of the folding bicycle and the design difficulty of the folding bicycle while meeting the strength requirements.

[0042] In other embodiments, the tripod 31 may include a plurality of first support columns 313, which are spaced apart to improve the strength. When the first inclined column 311 and the second inclined column 312 have sufficient strength, the first support column 313 may not be provided on the tripod 31 to reduce the weight of the folding bicycle.

[0043] In some embodiments, as Figure 1 、 Figure 4 shown, the tripod 31 may further include a second support column 314. One end of the second support column 314 may be fixedly connected to the first inclined column 311, and the other end may be fixedly connected to the second inclined column 312.

[0044] The front vehicle assembly 02 may further include a shock absorber 28. The shock absorber 28 may be detachably connected to the connecting plate 214. When the shock absorber 28 is worn to the limit, the shock absorber 28 can be quickly replaced. The shock absorber 28 may abut against the second support column 314. When the user drives the folding bicycle on bumpy roads, the shock absorber 28 can effectively absorb the impact force and improve the comfort of the user.

[0045] In some embodiments, as Figure 3 、 Figure 4As shown, the front vehicle component 02 may further include a third connecting portion 27. The third connecting portion 27 may be detachably connected to the crossbeam frame 211, which facilitates the maintenance of the third connecting portion 27 and the crossbeam frame 211.

[0046] The rear vehicle component 03 further includes a fourth connecting portion 33. The fourth connecting portion 33 is detachably connected to the support column, which facilitates the maintenance of the fourth connecting portion 33 and the support column.

[0047] The folded state may further include that the third connecting portion 27 is detachably connected to the fourth connecting portion 33. The detachable connection method may be snap connection or magnetic attraction connection, and magnetic attraction connection is preferably used. The magnetic attraction connection method can reduce the operation steps when the user folds. When the user moves the support column towards the crossbeam frame 211 until the third connecting portion 27 is detachably connected to the fourth connecting portion 33, the relative positions of the support column and the crossbeam frame 211 can be fixed, thus facilitating the storage of the folding bicycle.

[0048] In some embodiments, as Figure 1 、 Figure 5 shown, the seat assembly 04 may include a seat post 41, a seat plate 42, and a backrest 43. The rear riser 213 may be sleeved on the outer peripheral side of the seat post 41. The seat post 41 may be detachably connected to the rear riser 213, which facilitates the user to separate the seat post 41 from the rear riser 213, thereby further reducing the occupied space after the folding bicycle is folded. The seat plate 42 may be hinged to one end of the seat post 41 away from the rear riser 213, and the backrest 43 is hinged to one side of the seat plate 42. The user can move the seat post 41 and the backrest 43 towards the seat plate 42 respectively, thereby reducing the space occupied by the seat assembly 04. The seat post 41 can be used to support the seat plate 42. When the user rides the folding bicycle, the user can sit on the seat plate, reducing fatigue. At the same time, the user can also lean on the backrest 43 to relieve the discomfort of the waist and back, thereby improving the comfort of the user.

[0049] The folded state may further include that the minimum angle between the seat plate 42 and the backrest 43 is less than a fourth set angle (the fourth set angle may be 15°), and the minimum angle between the seat plate 42 and the central axis of the seat post 41 is less than a fifth set angle (the fifth set angle may be 15°), so that the seat plate 42, the backrest 43, and the seat post 41 are as closely attached as possible after folding, so that the seat assembly 04 is relatively flat and occupies less space after folding.

[0050] In other embodiments, as Figure 5 shown, the seat assembly 04 may further include a groove 44. The groove 44 is recessed from the side of the seat post 41 away from the seat plate 42 towards the side close to the seat plate 42. As Figure 1As shown, the front vehicle assembly 02 further includes a bolt 30 and a plurality of jack holes 29. The jack holes 29 penetrate the rear riser 213 along the radial direction of the rear riser 213, and the plurality of jack holes 29 are sequentially arranged at intervals along the axial direction of the rear riser 213. The bolt 30 can be detachably connected to any one of the jack holes 29 and penetrate the rear riser 213 through the jack hole 29. The groove 44 is adapted to the outer peripheral surface of the bolt 30, and the groove 44 abuts against the outer peripheral surface of the bolt 30. In this way, when the user is driving the folding bicycle, unnecessary rotation of the seat assembly 04 can be avoided, and the bolt 30 can also bear the weight of the seat assembly 04 to ensure driving safety. The plurality of jack holes 29 allow the user to freely adjust the height of the seat assembly 04 according to their own situation.

[0051] In some embodiments, as Figure 1 、 Figure 3 shown, the front vehicle assembly 02 may further include a handle 25. One end of the handle 25 can be detachably connected to the crossbar frame 211, and the other end extends away from the front wheel 22. When the user finishes folding the folding bicycle, the folding bicycle can be comfortably moved to a designated position by holding the handle 25.

[0052] The folded state may further include that the end of the handle 25 away from the front wheel 22 is spaced from the rotation center line of the rear wheel 32 by a second set distance (the second set distance may be the diameter of the rear wheel 32). When the user finishes folding the folding bicycle and needs to place it vertically with the rear riser 213 on top and the front riser 212 at the bottom, the end of the handle 25 away from the front wheel 22 and the two rear wheels 32 can simultaneously contact the ground, enabling the folding bicycle to be placed independently and stably on the ground.

[0053] In some other embodiments, when the user finishes folding the folding bicycle and needs to place it vertically with the rear riser 213 on top and the front riser 212 at the bottom, the end of the handle 25 away from the front wheel 22, the two rear wheels 32, and the front wheel 22 can simultaneously contact the ground, enabling the folding bicycle to be placed independently and stably on the ground.

[0054] In some embodiments, as Figure 1 shown, the front vehicle assembly 02 may further include a pedal 24. The pedal 24 is detachably connected to one end of the crossbar frame 211 close to the front riser 212. When the user is driving the folding bicycle, the user's feet can be placed on the pedal 24 to relax the leg muscles and improve user comfort.

[0055] In some embodiments, as Figure 1As shown, the front vehicle component 02 may further include a battery 23. The battery 23 may be detachably connected to the cross beam frame 211. The battery 23 may be disposed in the hollow cavity of the cross beam frame 211, which can make the folding bike more compact and enable the cross beam frame 211 to protect the battery 23, reducing the probability of the battery 23 being impacted by foreign objects. The battery 23 may be electrically connected to the front wheel 22 and / or the rear wheel 32, enabling the battery 23 to drive the front wheel 22 and / or the rear wheel 32 to rotate respectively, so that the folding bike can move according to the user's intention.

[0056] Those of ordinary skill in the art can understand that the above embodiments are specific cases for implementing the present disclosure. In actual applications, various changes can be made to them in terms of form and details without departing from the spirit and scope of the present disclosure.
