In the present application, a foldable bicycle will be mainly described as an example. Other portable appliances also have similar purposes and advantages, and therefore, the detailed description is omitted.

The inventor of this application discovers, among the prior art, general foldable bicycle is when folding, and main folding position is handlebar and roof beam, and the wheel can't be folded, puts into between two wheels with roof beam and handlebar folding back, and two wheels still have certain space not filled, and space utilization after folding is lower, and the space that occupies is still great, and the user throws after folding the bicycle and occupies great space, is unfavorable for carrying and saving.

In view of the above problems, a first embodiment of the present application provides a folding wheel, typically applicable to a folding portable appliance, and particularly to a portable bicycle, as shown in fig. 1, 2 and 3, the folding wheel comprising:

the wheel body 1 comprises two wheel plates which can be spliced with each other, the two wheel plates are provided with notches 21, and when the two wheel plates are spliced with each other, the two notches are spliced into a notched area 2;

a first connecting member 4 which can be connected between the two wheel plates and is disposed in the cutout region 2;

the first sliding rail mechanism is at least partially arranged on the first connecting piece 4, the rest parts are arranged on the two wheel plates, and the two wheel plates can be spliced or kept away along the first sliding rail mechanism in a sliding mode. For example, as shown in fig. 3, the first slide rail mechanism may include: a first track groove 31 and a first rotation shaft 32 fitted into the first track groove 31;

the fixing mechanism can fix the two wheel plates in a mutually spliced state.

Referring to fig. 2 and 3, wherein the two wheel plates may include a left wheel plate 11 and a right wheel plate 12, the first rail groove 31 includes: a first left rail portion 311 provided on the left wheel plate 11, and a first right rail portion 312 provided on the right wheel plate 12. The first rotating shaft 32 is also formed with two, which are a first left rotating shaft 321 and a first right rotating shaft 322, respectively, the first left rotating shaft 321 and the first right rotating shaft 322 are respectively arranged at two ends of the same side of the first connecting member 4, and the direction in which the first left rotating shaft 321 and the first right rotating shaft 322 are opposite to each other is the direction in which the two wheel plates are spliced. The first left rail portion 311 and the first right rail portion 312 are also formed along the splicing direction of the two wheel plates, wherein the first left rotating shaft 321 is slidably embedded in the first left rail portion 311; the first right rotating shaft 322 is slidably inserted into the first right rail portion 312.

It should be noted that, as shown in fig. 1 and 2, when the wheel body 1 is in the assembled position, the first connecting member 4 is located in the gap area 2, and the first connecting member 4 may be attached to the wheel plate in the axial direction of the first rotating shaft 32, or have a certain gap. When the wheel body 1 is in the split position, the first connecting piece 4 and the wheel plate have a gap, as shown in fig. 3, the first connecting piece 4 and the wheel plate are connected only by the first rotating shaft 32, and the first rotating shaft 32 needs to transmit the force of the synchronous rotation of the first connecting piece 4 and the wheel body 1, so that the requirement on the rigidity of the first rotating shaft 32 is high. Preferably, the first connecting member 4 in the present embodiment is completely inserted into the notch region 2, and each side edge of the first connecting member 4 is attached to the wheel plate. The first rotating shaft 32 is disposed on one side of the first connecting member 4, and the first track groove 31 is disposed on the wall of the wheel plate opposite to the first rotating shaft 32, so as to ensure that the wheel body 1 and the first connecting member 4 rotate synchronously.

From the above, the left wheel plate 11 can slide along the first left rail portion 311 through the first left rotation shaft 321, and the right wheel plate 12 can slide along the first right rail portion 312 through the first right rotation shaft 322; meanwhile, since the first left rotating shaft 321 and the first right rotating shaft 322 are both shafts, the left wheel plate 11 can be turned around the first left rotating shaft 321 as an axis relative to the first connecting member 4, and the right rotating shaft can be turned around the first right rotating shaft 322 as an axis relative to the first connecting member 4.

As shown in fig. 1, when a user is ready to fold and store the assembled wheel body 1, since the two wheel plates are in the assembled state, the assembled surfaces of the two wheel plates are completely abutted, and any one wheel plate cannot be turned over relative to the first connecting member 4, referring to fig. 2 and 3, the user firstly needs to hold the left wheel plate 11 and the right wheel plate 12 by hand and pull the two wheel plates in the direction of being far away, the first connecting member 4 and the first left rotating shaft 321 and the first right rotating shaft 322 thereon are not moved, and the two wheel plates respectively slide in the direction of being far away from each other along the first left track portion 311 and the first right track portion 312 which are respectively formed. After the abutting surfaces of the two wheel plates are separated to a position far enough, the first rotating shaft 32 is still located in the first track groove 31, the user can turn the left wheel plate 11 and the right wheel plate 12, fig. 4 and 5 are two states after the wheel body 1 is turned, obviously, when the left wheel plate 11 and the right wheel plate 12 are folded towards directions close to each other in fig. 4, the folded wheel body 1 occupies a smaller space, the size of the folded bicycle is convenient to reduce, and the folded bicycle is convenient to store or carry.

It should be noted that, in order to minimize the occupied space of the folded wheel body 1, the two wheel plates in the embodiment are both in a semicircular shape and have the same size, and after the wheel body 1 is folded, the two wheel plates are symmetrical, so that the phenomenon that extra protrusions are generated in the unilateral direction to occupy more space is avoided. Of course, the two wheel plates may have differences in shape and size, and the shape and size of the two wheel plates are only the same in this embodiment, and are not particularly limited.

In addition, since the two wheel plates in the present embodiment have the same shape and size, the first connecting member 4 is disposed in the middle of the wheel body 1, and the wheel axle of the bicycle penetrates through the center of the first connecting member 4 to drive the wheel body 1 to rotate.

In addition, as shown in fig. 4, when the two wheel plates are separated from each other and turned over relative to the first connecting member 4, the space of the notch 21 is not utilized, and the occupied space after folding is increased, in actual operation, after both the wheel plates are turned over relative to the first connecting member 4, the first connecting member 4 can also slide along the first track groove 31, the first connecting member 4 is clamped into the notch 21 of the wheel plate, which is different from the wheel plate splicing, the first connecting member 4 is clamped into the notch 21 of the turned wheel plate along the thickness direction, so that the space of the notch 21 is utilized again, and the space of the folded wheel body 1 is further reduced.

After two wheel boards amalgamate, through fixed establishment with two wheel board lockings, avoid the user to appear wheel body 1 separation when riding the bicycle, take place danger. The fixing mechanism can be realized in various ways, including clamping, screwing and the like. Taking the screw connection as an example, semicircular bulges can be respectively arranged on the two wheel plates, and threaded holes are respectively formed in each semicircular bulge and staggered in the thickness direction of the wheel plate. When two round plates amalgamation, two protruding screw holes of semicircle coincide in the thickness direction, the user can pass two screw holes simultaneously through the bolt this moment to lock two round plates.

In order to ensure the stability of the fixing, each wheel plate in this embodiment is provided with two locking portions, and the two locking portions are symmetrical with respect to the axis of the wheel body 1. Of course, the fixing mechanism may be in other forms, and the present embodiment is only an example of a snap ring and is not particularly limited.

Meanwhile, it is worth noting that, when the wheel body is folded, the left wheel plate 11 rotates around the first left rotating shaft 321, the right wheel plate 12 rotates around the first right rotating shaft 322, but the first left rotating shaft 321 and the first right rotating shaft 322 are arranged on one side of the first connecting part 4, and in order to ensure the stability of the wheel body turning, the folding wheel can further include: and the second slide rail mechanism.

Wherein the second rotating shaft 34 and the first rotating shaft 32 are disposed at opposite sides of the first connecting member 4, and the second track groove 33 is also opposite to the first track groove 31.

The second rail groove 33 may include: a second left rail portion 331 provided on the inner wall of the notch 21 of the left wheel plate 11, and a second right rail portion 332 provided on the inner wall of the notch 21 of the right wheel plate 12; the second rotating shaft 34 is formed with two, respectively, a second left rotating shaft 341 and a second right rotating shaft 342, the second left rotating shaft 341 is slidably inserted into the second left rail portion 331, and the second right rotating shaft 342 is slidably inserted into the second right rail portion 332.

It is noted that the second left rotating shaft 341 and the first left rotating shaft 321 can be coaxially disposed, and the second right rotating shaft 342 and the first right rotating shaft 322 can be coaxially disposed. So set up and make left wheel board 11 when sliding, first left pivot 321 and second left pivot 341 realize the synchronous slip, keep balance, and right wheel board 12 is the same, can avoid the wheel board to take place the sideslip when sliding.

Meanwhile, the left wheel plate 11 can rotate around the common axis of the first left rotating shaft 321 and the second left rotating shaft 341 when rotating, the first left rotating shaft 321 and the second left rotating shaft 341 ensure the stability of the left wheel plate 11 when rotating, and the right wheel plate 12 is the same.

In addition, as shown in fig. 6 and 7, the folding wheel is provided with a first stop structure in the first track groove 31, and a second stop structure in the second track groove 33, and the first stop structure and the second stop structure are used for limiting the separation distance between the two wheel plates, and as shown in fig. 7, the first stop structure may include: a first left stop block 61 provided in the first left rail portion 311, and a first right stop block 62 provided in the first right rail portion 312. As shown in fig. 6, the second stop structure may include: a second left stopper 63 provided in the second left rail portion 331, and a second right stopper 64 provided in the second right rail portion 332.

As shown in fig. 7, when the two wheel plates are pulled in the direction away from each other, the first left rotating shaft 321 slides in the first left rail portion 311, and after sliding for a certain distance, the first left rotating shaft 321 abuts against the first left stop block 61, and at this time, the position of the left wheel plate 11 is the limit distance for pulling the left wheel plate 11, and similarly, the right wheel plate 12 also abuts against the first right stop block 62 when pulling for a certain distance, and this position is the limit distance for pulling the right wheel plate 12. The first left stop block 61 and the first right stop block 62 are arranged to avoid the situation that the first rotating shaft 32 is separated from the first track groove 31 due to an overlarge pulling distance when the wheel plate is pulled, and the second stop structure is the same.

In order to ensure the sliding tracks of the two wheel plates, as shown in fig. 6 and 7, a first guide strip 71 is arranged between the first left rotating shaft 321 and the first right rotating shaft 322 of the first connecting plate, a second guide strip 72 is arranged between the second left rotating shaft 341 and the second right rotating shaft 342, the first guide strip 71 and the second guide strip 72 can be arranged in a strip shape, and the length direction is arranged along the splicing direction of the two wheel plates.

As shown in fig. 7, when the left wheel plate 11 and the right wheel plate 12 approach each other, the left end of the first guide bar 71 enters the first left rail portion 311, and the right end of the first guide bar enters the first right rail portion 312, so as to assist in guiding the splicing of the two wheel plates when the two wheel plates approach each other, so as to define the splicing direction of the two wheel plates, and avoid the situation that the two wheel plates are not spliced smoothly due to the fact that the two wheel plates are turned over along the first rotating shaft 32 when the wheel plates are spliced with each other.

When the first stop structure is disposed in the first track groove 31, the length of the first guide bar 71 is limited. When two of them wheel boards are pieced together, the distance between first left stop block 61 and first right stop block 62 is first predetermined length, and it is obvious that, in order to guarantee the normal piecing together of two wheel boards, the length of first guide strip 71 can not be greater than first predetermined length. In this embodiment, the length of the first guide strip 71 is equal to a first preset length, after the two wheel plates are mutually spliced, two ends of the first guide strip 71 respectively abut against the first left stop block 61 and the second right stop block 64, the stability of the two wheel plates after being mutually spliced is further improved, with reference to fig. 6, the length of the second stop strip 72 is the same as that of the first stop strip 71, the two wheel plates are spliced by guiding the second track groove 33, and the stability of the two wheel plates is improved.

It should be noted that, as shown in fig. 12, the plate 9 is attached to the split wheel body 1 and is disposed coaxially with the wheel body 1, and when the first connecting member 4 and the second connecting member 8 rotate relatively, the plate 9 and the wheel body 1 also rotate relatively.

As shown in fig. 13 and 14, the illustrated position is a first preset position where the plate body 9 rotates along with the second connecting member 8, the two fixing plates correspond to the two wheel plates one to one and are respectively attached to the corresponding wheel plates, when the plate body 9 is located at the first preset position, the fixing mechanism does not lock the wheel plates, and the fixing plates can be folded along with the wheel plates. In the present embodiment, the left wheel plate 11 corresponds to the left fixing plate 91 and the right wheel plate 12 corresponds to the right fixing plate 92, for example, in actual operation, the left wheel plate 11 may correspond to the right fixing plate 92, and the right wheel plate 12 may correspond to the left wheel plate 11. When the wheel plate and the fixing plate are folded, the wheel plate and the fixing plate attached thereto move integrally, and when a user pulls the left wheel plate 11 and the right wheel plate 12 in a direction away from each other, the fixing plate attached to each wheel plate moves together with each wheel plate. And the fixed plate can overturn relative to the second connecting piece 8 along with the overturn of the corresponding wheel plate, so that the synchronous overturn of the fixed plate is realized.

When a user uses the bicycle, the wheel plates need to be spliced and fixed through the fixing mechanism, the plate bodies 9 rotate along with the second connecting piece 8, as shown in fig. 12, the spliced plate bodies 9 in the positions shown in the drawing are second preset positions rotating along with the second connecting piece 8, at the moment, in combination with the drawings of fig. 9, 10 and 12, the second splicing half holes 94 on the two fixing plates are spliced to form a second splicing hole 95 which is overlapped with the first fixing hole 13, and the first splicing half holes 14 are spliced to form a first splicing hole 15 which is overlapped with the second fixing hole 96. The plug-in unit 10 can simultaneously penetrate through the first fixing hole 13 and the second splicing hole 95, and the first splicing hole 15 and the second fixing hole 96, so as to fix the wheel body 1 and the plate body 9 in a splicing state, and a user can safely ride the bicycle.

In order to guarantee the stability of fixing, as shown in fig. 9, the first splicing hole 15, the second splicing hole 95, the first fixing hole 13 and the second fixing hole 96 are all provided with two, the two second fixing holes 96 and the two second splicing holes 95 are all symmetrical relative to the axis of the plate body 9, the two first fixing holes 13 and the two first splicing holes 15 are symmetrical relative to the axis of the wheel body 1, and the stability of locking is increased by splicing and locking at two positions. It should be noted that the second preset position is not limited to the position shown in the drawing, and the position where the second splicing hole 95 coincides with the first fixing hole 13 is the second preset position, which is unrelated to the angle of the plate 9 rotating along with the second connecting member 8, and the drawing only shows an example, and the splicing line of the plate 9 and the splicing line of the wheel body 1 may form any angle in the actual operation.

As shown in fig. 10 and 11, a third stop structure may be provided in the third rail groove 35, and a fourth stop structure may be provided in the fourth rail groove 37. A third guide strip 73 may be disposed between the third left rotating shaft 361 and the third right rotating shaft 362, a fourth guide strip 74 may be disposed between the fourth left rotating shaft 381 and the fourth right rotating shaft 382, the third guide strip 73 and the fourth guide strip 74 are both in a strip shape, and the length direction is set in a direction opposite to the left fixing plate 91 and the right fixing plate 92.

Wherein, the third stop structure may include: a third left stopper 65 provided in the third left rail portion 3, and a third right stopper 66 provided in the third right rail portion 352. The fourth detent structure may include: a fourth left stop block 67 provided in the fourth left rail portion 371, and a fourth right stop block 68 provided in the fourth right rail portion 372.

The third stop structure is used to prevent the third shaft 36 from separating from the third track groove 35, similar to the first stop structure. The fourth stop structure is used to prevent the fourth shaft 38 from disengaging from the fourth track groove 37. Like the first guide bar 71, the third guide bar 73 and the fourth guide bar 74 are used to guide the splicing of the two fixing plates and increase the stability after splicing.

In order to improve the splicing stability of the wheel body 1 and the plate body 9, when the two wheel plates are spliced, the first connecting piece 4 and the two wheel plates are mutually clamped; when the two fixing plates are spliced, the second connecting piece 8 and the two fixing plates are mutually clamped.

Similarly, as shown in fig. 13, the fixing plate is also engaged with the second connecting plate 8 when being assembled. Meanwhile, it is noted that when the wheel plate and the fixing plate rotate synchronously, the wheel plate is easily blocked to cause that the turning cannot be smoothly performed, and fig. 16 illustrates a left wheel plate 11 and a left fixing plate 91 as an example, because the wheel plate and the fixing plate move synchronously, the first left rotating shaft 321 and the third left rotating shaft 361 are opposite in the thickness direction of the first connecting piece 4, but when the left wheel plate 11 and the left fixing plate 91 rotate synchronously, if the left fixing plate 91 rotates towards the first left rotating shaft 321, the first left rotating shaft 321 blocks the rotation of the left fixing plate 91; if the left fixing plate 91 rotates in a direction away from the first left rotating shaft 321, that is, the left wheel plate 11 rotates in a direction of the third left rotating shaft 361, the third left rotating shaft 361 blocks the left wheel plate 11 from rotating. No matter which direction the wheel plate and the fixed plate rotate, the wheel plate and the fixed plate can be blocked by the rotating shaft, and the right wheel plate 12 is the same.

In view of this, in the present embodiment, as shown in fig. 17, the first left rotating shaft 321 and the third left rotating shaft 351 are staggered in the thickness direction of the first connecting member 4, the distance between the first left rotating shaft 321 and the first right rotating shaft 322 is smaller than the distance between the third left rotating shaft 351 and the third right rotating shaft 352, when the left fixing plate 91 rotates towards the first left rotating shaft 321, the first rotating shaft 321 does not block the left fixing plate 91, and the right fixing plate 92 is similar to the first left rotating shaft, so as to ensure the smooth turning of the fixing plate.
