Although certain features may be combined together to illustrate a possible system design, such features may be used in other combinations not explicitly described. Thus, unless otherwise indicated, the illustrated combinations are not intended to be limiting.

Referring to fig. 1 to 8, a spoke according to an embodiment of the present disclosure includes a spoke body 1, a stop collar 2 and a docking cap 3.

The spoke body 1 includes two connecting sections 11 at both ends of the spoke body 1, respectively, and a main section 12 connecting the two connecting sections 11.

The stop collar 2 is equipped with two, corresponds the both ends of spoke body 1 respectively, and stop collar 2 cover is located on linkage segment 11, and stop collar 2 and linkage segment 11 are formed with the location cooperation structure that prevents stop collar 2 along the axial displacement of spoke, and stop collar 2 is first spacing face 21 towards the terminal surface of another stop collar 2.

The butt joint cap 3 is provided with two, corresponds the both ends of spoke body 1 respectively, is equipped with first embedded groove 31 and the second embedded groove 32 that are linked together in the butt joint cap 3, and the size of first embedded groove 31 is greater than the size of second embedded groove 32 to form the second spacing face 33 of connecting first embedded groove 31 and second embedded groove 32, and stop collar 2 is located through first embedded groove 31 cover to butt joint cap 3, locates spoke body 1 through the cover of second embedded groove 32.

Wherein the first stop surface 21 and the second stop surface 33 form a stop fit preventing the docking cap 3 from being pulled away from the spoke body 1.

Through above-mentioned structural design, stop collar 2 and linkage segment 11 are formed with the location cooperation structure that prevents stop collar 2 along the axial displacement of spoke, can avoid stop collar 2 to be pulled away from spoke body 1 under the pulling force and lead to both to separate. Based on can avoiding stop collar 2 to be pulled away from the basis of the design of spoke body 1, stop collar 2's first spacing face 21 and the second spacing face 33 of butt joint cap 3 form and prevent butt joint cap 3 by the spacing cooperation of pulling away from spoke body 1, can avoid butt joint cap 3 to be pulled away from spoke body 1 under the pulling force and lead to both to separate. The connection stability of the spoke is improved.

In addition, in the related art, after the two ends of the spoke body 1 are wrapped and fixed to form the fixed joint, taper is also required to be machined by a blanking machining method, and the machining process is troublesome. The spokes of the embodiment of the disclosure do not need to process the limit sleeve 2, so that the production process is simplified.

Referring to fig. 2 and 3, and referring to fig. 7, in this embodiment, the connecting section 11 and the connecting surface 13 of the stop collar 2 have portions recessed inward in the radial direction of the spoke. The recessed portions form a locating engagement structure. Specifically, the connecting section 11 is provided with a first connecting surface 111 for connecting the stop collar 2, the first connecting surface 111 is recessed inwards along the radial direction of the spoke, the stop collar 2 is provided with a second connecting surface 22 for connecting the connecting section 11, and the second connecting surface 22 is recessed inwards along the radial direction of the spoke. When the stop collar 2 is sleeved on the connecting section 11, the first connecting surface 111 is attached to the second connecting surface 22.

In other embodiments, the connecting section 11 and the connecting surface 13 of the stop collar 2 have portions that project radially outwardly of the spokes. The protruding portions form a locating engagement.

In this embodiment, the concave portion has only one place, wherein both ends of the concave portion have smooth transition. In other embodiments, the concave portion may be formed by a plurality of points, and the connecting surface 13 may be formed in a wave shape. Of course, the two ends of the concave portion may be vertically transited, and the connection surface 13 may be serrated.

The spoke body 1 and the limit sleeve 2 are made of carbon fiber materials. The manufacturing process of the spoke body 1 and the stop collar 2 can comprise that the spoke body 1 is molded by adopting a die, and the concave part can be directly molded by the die or can be a concave part processed after the spoke body 1 with the same diameter is molded by the die. Then, carbon fiber is wound outside the concave part of the spoke body 1, and the spoke body is put into a die to be secondarily molded to form the limit sleeve 2.

The stop collar 2 can also be made of metal materials and is clamped on the concave part of the spoke body 1.

It should be noted that the spoke body 1 is a unitary structure and is not split, and the two connecting sections 11 and the main section 12 are defined for convenience of description.

The butt joint cap 3 is made of metal materials, so that the limit fit formed by the first limit surface 21 and the second limit surface 33 has better strength, and the connection stability of the spoke is further improved.

The first limiting surface 21 and the second limiting surface 33 are perpendicular to the axial direction of the spoke body 1, so that the pulling force can be more effectively resisted, and the butt joint cap 3 and the spoke body 1 are prevented from being separated.

The installation process that stop collar 2 and spoke body 1 were located to butt joint cap 3 cover can include, after shaping out spoke body 1, establishes butt joint cap 3 cover on spoke body 1 earlier, then secondarily forming out stop collar 2 again, and two butt joint caps 3 are moved to the direction that keeps away from each other to the pulling, makes butt joint cap 3 locate stop collar 2 through first embedded groove 31 cover, locates spoke body 1 through second embedded groove 32 cover, like fig. 7 through 8.

The main body section 12 has an equal diameter structure, and the second insert groove 32 has a size larger than that of the main body section 12. Thus, the two butt caps 3 can move more smoothly in the direction away from each other on the spoke body 1.

Referring to fig. 5, the end of the first insertion groove 31 far away from the second insertion groove 32 has an expanded diameter structure, which is more beneficial for the stop collar 2 to enter the first insertion groove 31 when the two butt caps 3 move away from each other.

Referring to fig. 4, the peripheral wall of the docking cap 3 is provided with a threaded portion 34 and a plurality of flat sections 35. The threaded portion 34 is located at an end of the docking cap 3 remote from the other docking cap 3. A plurality of planar segments 35 are located at an end of the docking cap 3 adjacent to another docking cap 3. The threaded part 34 on one butt joint cap 3 is used for being screwed on the rim for fixing, and the threaded part 34 on the other butt joint cap 3 is used for being screwed on the hub for fixing. The plurality of planar segments 35 facilitate wrench rotation of the docking cap 3.

The two connecting sections 11 have the same shape, the two limiting sleeves 2 have the same shape, and the two butt joint caps 3 have the same shape. The manufacturing difficulty and the manufacturing cost are reduced. In other embodiments, the shapes of the two connecting sections 11 may be different, the shapes of the two limiting sleeves 2 may be different, and the shapes of the two butt caps 3 may be different.

An embodiment of the present disclosure provides a hub comprising a rim, a hub, and spokes of any of the above embodiments, wherein one of the docking caps 3 is connected to the rim and the other docking cap 3 is connected to the hub. The advantageous effects of this hub can be seen from the embodiments of the spokes described above.

An embodiment of the present disclosure provides a bicycle including the hub, and the hub has the advantages of the spokes of any one of the embodiments, so the bicycle also has the advantages of the spokes of any one of the embodiments.
