[0032] In the application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any embodiment described as exemplary in this application is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the application. Details are set forth in the following description for purpose of explanation. It should be appreciated that one of ordinary skill in the art will readily recognize that the application can be practiced without the use of these specific details. In other instances, well-known structures and processes have not been described in detail in order to avoid obscuring the description of the application. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded with the widest scope consistent with the principles and features disclosed.

[0033] See Figure 1 and Figure 3 The application provides a folding wheel for a bicycle, comprising:

[0034] a first hub 1 ;

[0035] a second hub 2, which is arranged opposite to the first hub 1 ;

[0036] a hub shaft 3, the first hub 1 and the second hub 2 are sleeved on the hub shaft 3, and the first hub 1 and the second hub 2 can move relatively or oppositely along the hub shaft 3 ;

[0037] a plurality of tire segments 4, which are connected to each other to form a complete tire, the tire segments 4 are provided with a first track 41 and a second track 42 extending along the length direction of the tire segments 4 ;

[0038] a plurality of spoke assemblies 5, the spoke assemblies 5 include a first spoke 51 and a second spoke 52, the first spoke 51 has a first end 511 and a second end 512 arranged opposite along the length direction thereof, the first end 511 is hinged to the edge of the first hub 1, and the second end 512 is located in the first track 41 and can slide in the first track 41 ; the second spoke 52 has a third end 521 and a fourth end 522 arranged opposite along the length direction thereof, the third end 521 is hinged to the edge of the second hub 2, and the fourth end 522 is located in the second track 42 and can slide in the second track 42 ; the middle part of the first spoke 51 is hinged to the middle part of the second spoke 52.

[0039] The folding bicycle wheel is mainly achieved by the relative or opposite movement of the first hub 1 and the second hub 2 on the hub central axis 3, and the spoke assembly 5 on the first hub 1 and the second hub 2 moves synchronously. When the folding bicycle wheel is transformed from a complete wheel shape to a folding state, the first hub 1 and the second hub 2 move towards each other, and the spoke assembly 5 rotates, and the tire segment 4 rotates to be parallel or close to parallel to the hub central axis 3. Here, close to parallel means that the angle between the tire segment 4 and the hub central axis 3 is small. Thus, the complete tire is folded from a large area shape to a small area shape, and the folding of the wheel is completed. Here, the comparison of the area is that, when the wheel is not folded, it is a complete circle, and the radius is the radius of the first hub 1 plus the length of the spoke assembly 5 plus the thickness of the tire segment 4; and after folding, the area is close to the area of the first hub 1. Obviously, the wheel has obvious folding effect through the above technical scheme.

[0040] It should be noted that the first hub 1 and the second hub 2 each have a certain accommodating space for accommodating the hub central axis 3. Specifically, when the wheel is in a complete wheel state, the first hub 1 and the second hub 2 contact each other, and a part of the hub central axis 3 is accommodated in the accommodating space of the first hub 1, and the other part is accommodated in the accommodating space of the second hub 2.

[0041] In some embodiments, referring to Figure 2 , the first track 41 and the second track 42 are oppositely arranged along the length direction of the tire segment 4, and the first track 41 and the second track 42 are located on the same straight line, the shapes of the first track 41 and the second track 42 are waist hole shapes, the sizes of the first track 41 and the second track 42 are the same, the first track 41 and the second track 42 are symmetrically arranged with the center line of the tire segment 4 as the axis of symmetry. In addition, the middle part of the first spoke 51 is hinged to the middle part of the second spoke 52, the lengths of the first spoke 51 and the second spoke 52 are the same, and the first spoke 51 and the second spoke 52 can move synchronously when moving, that is, the rotating angles of the first spoke 51 and the second spoke 52 and the moving distances of the second end 512 and the fourth end 522 in the track are the same, which is convenient for production and manufacturing and makes the movement of each component more stable when folding.

[0042] In some embodiments, referring to Figure 2 and Figure 4, the folded wheel has a folded state and an unfolded state. The unfolded state refers to a state in which a plurality of tire segments 4 are spliced with each other to form a complete tire shape. For the convenience of understanding and description, the tire in the unfolded state is defined as horizontal, and the tire in the folded state is defined as vertical. Of course, whether the wheel is horizontal or vertical, or inclined, is determined according to actual use or placement, and is not limited. When the folded wheel needs to be deformed from the unfolded state to the folded state, the specific deformation process is as follows: first, the user applies a pulling force to the first hub 1, so that the first hub 1 moves away from the second hub 2 along the hub central axis 3. The first end 511 of the first spoke 51 moves with the first hub 1. Since the first end 511 moves away from the second hub 2, the second end 512 of the first spoke 51 also moves. The first track 41 of the tire segment 4 limits the movement of the second end 512, so that it can only move in the first track 41, thereby making the tire segment 4 have a tendency to move towards the first hub 1. For the second spoke 52, although it is not connected to the first hub 1, its third end 521 is connected to the second hub 2, and the middle part of the second spoke 52 is hinged to the middle part of the first spoke 51. Therefore, when the first spoke 51 moves, the second spoke 52 will move synchronously due to the movement of the first spoke 51 and the change of the relative distance between the first hub 1 and the second hub 2. The fourth end 522 of the second spoke 52 moves in the second track 42 along with the movement of the third end 521. Since the relative movement direction of the first hub 1 and the second hub 2 is the vertical direction, the first spoke 51 and the second spoke 52 will move from the horizontal state to the vertical state during the movement. In the movement process, the second end 512 and the fourth end 522 are located in the first track 41 and the second track 42 of the tire segment 4 respectively, which drives the tire segment 4 to move from the horizontal state to the vertical state. Thus, the folding of the folded wheel is completed.

[0043] It should be noted that when the folded wheel is in the folded state, the first hub 1 and the second hub 2 are relatively arranged in the vertical direction, and the first spoke 51 and the second spoke 52 are located between the first hub 1 and the second hub 2. The second end 512 is located at the end of the first track 41 farthest from the second track 42, and the fourth end 522 is located at the end of the second track 42 farthest from the first track 41, which can support the first hub 1 and the second hub 2. Even without separately setting a component for locking the first hub 1 and the second hub 2, the first hub 1 and the second hub 2 will not move without external force, ensuring the stability of the wheel structure in the folded state.

[0044] When the folding wheel needs to switch from the folded state to the unfolded state, the user only needs to press the first hub 1 to move the first hub 1 towards the second hub 2. At the same time, the first spoke 51 and the second spoke 52 also move accordingly, specifically, the first end 511 of the first spoke 51 rotates, the second end 512 moves in the first track 41 towards the second track 42, the third end 521 of the second spoke 52 rotates, the fourth end 522 moves in the second track 42 towards the first track 41, and the first spoke 51 and the second spoke 52 also rotate relative to each other, driving the tire segment 4 to rotate from the vertical state to the horizontal state. When the plurality of tire segments 4 are all rotated to the horizontal state, the adjacent tire segments 4 are connected to each other, completing the switching of the wheel from the folded state to the unfolded state.

[0045] Further, the first spoke 51 has an angle between the extension line in the length direction and the extension line of the hub central axis 3, which is equivalent to the first spoke 51 having an angle with the vertical direction. Similarly, the second spoke 52 also has the same angle between the extension line in the length direction and the extension line of the hub central axis 3. The angle can be 70° to 90°, and the angle in the embodiment is 80°. By limiting the angle between the first spoke 51 and the second spoke 52 relative to the extension line of the hub central axis 3, the user can press the first hub 1 more easily when switching from the folded state to the unfolded state, that is, the first hub 1 can move towards the second hub 2.

[0046] In some embodiments, please refer to Figure 5 , in order to ensure that the folding wheel can improve the stability that the first hub 1 and the second hub 2 do not move along the hub central axis 3 in the unfolded state, the folding wheel further comprises a locking member 6 for locking and fixing the first hub 1 and the second hub 2 in the unfolded state. For the locking member 6, the structure thereof will be described in detail below:

[0047] Please refer to Figure 1 , Figure 3 and Figure 5 , the locking member 6 comprises a clamping portion 61, the clamping portion 61 has a clamping state and an open state, one side of the clamping portion 61 is connected with the first hub 1, the second hub 2 has a second central axis portion 21, a clamping groove is formed on the surface of the second central axis portion 21, when the folding wheel is in the unfolded state and the clamping portion 61 is in the clamping state, the clamping portion 61 is located in the clamping groove to fix the first hub 1 and the second hub 2, when the clamping portion 61 is in the open state, the clamping portion 61 is separated from the clamping groove, and the first hub 1 and the second hub 2 can move relative to each other.

[0048] The locking member 6 further comprises a force applying part 62 which is integrally connected with the clamping part 61, the first hub 1 has a first middle shaft part 11, the force applying part 62 is hinged with the first middle shaft part 11, and the force applying part 62 is used to control the clamping part 61 to switch between the clamping state and the unfolded state.

[0049] Further description is made to the structure of the locking member 6: the force applying part 62 of the locking member 6 is two force applying plates which are respectively located at two sides of the first middle shaft part 11, the first middle shaft part 11 has a hinged part which protrudes from the side surface thereof, the two force applying plates are respectively hinged with the hinged part, and the force applying plates are provided with return springs which are sleeved on the hinged part, when the force applying plates are forced to rotate around the hinged part, the force applying plates have a tendency to return to the initial state due to the return characteristic of the springs, and when the external force applied to the force applying plates disappears, the force applying plates return to the initial position. The user can press the two force applying plates to make the force applying plates rotate around the hinged part, and the rotating direction is the direction in which the two force applying plates approach each other. The clamping part 61 of the locking member 6 is two clamping arms which are integrally connected with the two force applying plates. When the two force applying plates are forced to approach each other, the clamping arms move away from each other due to the lever principle, and the clamping arms are in the unfolded state; when the force applied to the force applying plates is removed, the two force applying plates return to the initial state due to the return force of the springs, and the two clamping arms approach each other. If the first hub 1 and the second hub 2 contact each other at this time, i.e. the folding tire is in the unfolded state, the two clamping arms approach each other due to the disappearance of the external force, and the two clamping arms are located in the clamping grooves, thereby completing the connection and fixation of the first hub 1 and the second hub 2 which are in the unfolded state.

[0050] In some embodiments, the tire section 4 is provided with a connecting part at both ends, and the adjacent tire sections 4 are detachably connected through the connecting parts when the folding tire is in the unfolded state. The connection mode between the adjacent connecting parts can be buckle connection, embedded connection, threaded bolt connection, etc., and is not specifically limited.

[0051] It should be further noted that in some embodiments, the six tire segments 4 and the six spoke assemblies 5 are connected in sequence to form a complete tire, and the six tire segments 4 are connected to the six spoke assemblies 5 respectively. In addition, the first hub 1 and the second hub 2 are respectively provided with six hinge positions, and the six hinge positions on the first hub 1 are hingedly connected to the six first spokes 51 respectively, and the six hinge positions on the second hub 2 are hingedly connected to the six second spokes 52 respectively. The six hinge positions on the first hub 1 are uniformly distributed along the circumference of the first hub 1, and the six hinge positions on the second hub 2 are uniformly distributed along the circumference of the second hub 2. When the folding wheel changes from the folded state to the unfolded state, the six tire segments 4 move synchronously with the first hub 1 moving towards the second hub 2; similarly, when the folding wheel changes from the unfolded state to the folded state, the six tire segments 4 move synchronously with the first hub 1 moving away from the second hub 2.

[0052] The application also provides a bicycle, which comprises a foldable frame and a folding wheel as described in any one of the preceding embodiments, and the folding wheel is arranged at the tire mounting position of the foldable frame, thereby solving the problem that the folding effect of the bicycle is not ideal due to the size of the tire being unable to be changed.
