Referring to fig. 1-3, an embodiment of the present application provides a frame 100 including a five-way pipe 20 and a middle pipe 30. The middle pipe 30 is connected with the five-way pipe 20. Wherein, the middle pipe 30 is used for installing a saddle, the five-way pipe 20 is used for installing a crank, and a pedal is arranged on the crank.

Further, referring to fig. 4, the middle tube 30 includes a hollow first tube 31, and the first tube 31 is connected to the five-way tube 20. The first tube 31 extends in a first extending direction Z.

The first tube 31 has a first central axis extending along the first extending direction Z, and two ends of the first tube 31 in the axial direction X of the five-way tube 20 are symmetrically arranged about the first central axis, that is, the first tube 31 is an axisymmetric structure symmetrically arranged about the first central axis. It is contemplated that in other embodiments, the first tube 31 may be configured with a non-axisymmetric structure, which is not limited herein.

With continued reference to fig. 4-6, the middle tube 30 further includes a first reinforcing portion 32, and in the axial direction X of the five-way tube 20, the first reinforcing portion 32 is protruding on the tube wall of at least one end of the first tube body 31, the first reinforcing portion 32 extends along the first extending direction Z, and the position of the first tube body 31 where the first reinforcing portion 32 is protruding forms a first thickened portion of the middle tube 30. That is, the wall thickness of the portion of the middle tube 30 having the first reinforcing portion 32 is larger than that of the other portions. By providing the first reinforcement 32, the wall thickness of the tube wall of at least one end of the center tube 30 in the axial direction X of the five-way tube 20 is increased, so that the rigidity of at least one end of the center tube 30 in the axial direction X of the five-way tube 20 is increased, that is, the rigidity of at least one end of the center tube 30 in the left-right direction (the lateral rigidity of the center tube 30) can be increased, and the risk of the frame 100 deforming laterally during pedaling can be reduced.

Further, the frame 10 further includes a main beam tube 10, the main beam tube 10 includes a hollow second tube body, the first tube body 31 connects the second tube body with the five-way tube 20, and the second tube body extends along the second extending direction Y. Specifically, the first extending direction Z and the second extending direction Y intersect with the axial direction X of the five-way pipe 20 (extending direction of the five-way pipe 20) two by two. In some embodiments, the first tube 31 extends vertically, and the second tube extends horizontally, and at this time, the first extending direction Z and the second extending direction Y are perpendicular to the axial direction X of the five-way tube 20. In other embodiments, the first tube 31 does not extend vertically, and the second tube does not extend horizontally, and at this time, the first extending direction Z and the second extending direction Y intersect, but are not vertical, but the axial direction X of the five-way tube 20 is perpendicular to both the first extending direction Z and the second extending direction Y.

The second pipe body has a second central axis extending along the second extending direction Y, and two ends of the second pipe body in the axial direction X of the five-way pipe 20 are symmetrically arranged about the second central axis, that is, the second pipe body has an axisymmetric structure symmetrically arranged about the second central axis. It is contemplated that in other embodiments, the second tube may be configured with a non-axisymmetric structure, which is not limited herein.

The main beam pipe 10 further comprises a second reinforcing part, the second reinforcing part is convexly arranged on the pipe wall of at least one end of the second pipe body in the axial direction X of the five-way pipe 20, the second reinforcing part extends along the second extending direction Y, and the position of the second pipe body, on which the second reinforcing part is convexly arranged, forms a second thickened part of the main beam pipe 10. That is, the wall thickness of the portion of the main beam pipe 10 having the second reinforcing portion is greater than that of the other portion. By providing the second reinforcing portion, the wall thickness of the pipe wall of at least one end of the main beam pipe 10 in the axial direction X of the five-way pipe 20 is increased, so that the rigidity of at least one end of the main beam pipe 10 in the axial direction X of the five-way pipe 20 is increased, that is, the rigidity of at least one end of the main beam pipe 10 in the left-right direction (the lateral rigidity of the main beam pipe 10) can be increased, and the risk of lateral deformation of the frame 100 can be reduced in the tread process.

Here, the right and left directions described above mean: the left-right direction of the rider is parallel to the axial direction X of the five-way tube 20 when the rider rides the bicycle. The rigidity refers to the ability of a material or structure to resist deformation, i.e., to resist elastic deformation or displacement when the material or structure is subjected to an external force, and generally, the larger the rigidity is, the larger the stress required for deformation. That is, within the rigidity range of the material or structure, deformation does not occur easily.

It is contemplated that in other embodiments, the main rail 10 may be omitted from the frame 100, and is not limited in this regard.

In some embodiments, in the axial direction X of the five-way pipe 20, the two ends of the pipe body are provided with reinforcing parts, and the inner walls and the outer walls of the two ends of the pipe body are provided with reinforcing parts in a protruding manner. With continued reference to fig. 4, for the middle tube 30, in the axial direction X of the five-way tube 20, the two ends of the first tube body 31 are provided with first reinforcing portions 32, and the inner walls and the outer walls of the two ends of the first tube body 31 in the axial direction X of the five-way tube 20 are provided with first reinforcing portions 32 in a protruding manner. So set up, increased the wall thickness of the pipe wall at middle pipe 30 both ends in the axial X of five-way pipe 20, the both ends of middle pipe 30 all form first thickening portion, consequently increased the rigidity at middle pipe 30 both ends in the axial X of five-way pipe 20, namely, can increase the rigidity at middle pipe 30 both ends in the left and right directions, can reduce the risk of frame 100 lateral deformation at the in-process of stepping on. For the main beam pipe 10, on the axial direction X of the five-way pipe 20, two ends of the second pipe body are respectively provided with a second reinforcing part, and the inner walls and the outer walls of the two ends of the second pipe body on the axial direction X of the five-way pipe 20 are respectively provided with a second reinforcing part in a protruding mode. So set up, increased the wall thickness of girder pipe 10 the pipe wall at the axial X of five-way pipe 20 on both ends, the both ends of girder pipe 10 all form the second thickening portion, consequently increased the rigidity at the both ends of girder pipe 10 on the axial X of five-way pipe 20, namely, can increase the rigidity at the both ends of girder pipe 10 in the left and right directions, can reduce the risk of frame 100 lateral deformation at the in-process of stepping on.

In some embodiments, the cross-sectional shape of the tube body is annular. The annular pipe body is provided with reinforcing parts at both ends in the axial direction X of the five-way pipe 20. In other embodiments, the cross-section of the pipe body is elliptical, the major axis direction of the elliptical is parallel to the axial direction X of the five-way pipe 20, and both ends of the elliptical pipe body in the axial direction X of the five-way pipe 20 are provided with reinforcing parts. By setting the cross-sectional shape of the pipe body to an elliptical ring shape such that the outer diameter of the cross section in the axial direction X of the five-way pipe 20 is larger than the outer diameter thereof in the short axis direction, the rigidity of the pipe body in the axial direction X of the five-way pipe 20 can be increased.

It is conceivable that in other embodiments, a reinforcing portion may be provided at one end of the pipe body in the axial direction X of the five-way pipe 20, and in this case, the rigidity of the middle pipe 30 or the main beam pipe 10 in the axial direction X of the five-way pipe 20 may be increased, which is not limited herein.

In some embodiments, the reinforcement is of equal extension to its corresponding tube. With continued reference to fig. 1, for the middle tube 30, the extension length of the first reinforcement portion 32 in the first extension direction Z is equal to the extension length of the first tube body 31 in the first extension direction Z. For the main beam pipe 10, the extension length of the second reinforcement portion in the second extension direction Y is equal to the extension length of the second pipe body in the second extension direction Y. By such arrangement, the lateral rigidity of the middle tube 30 in the first extending direction Z can be increased, the lateral rigidity of the main beam tube 10 in the second extending direction Y can be increased, and the risk of lateral deformation of the frame 100 during pedaling can be reduced.

It is conceivable that in other embodiments, the relationship between the extending length of the reinforcing portion and the extending length of the corresponding pipe body is not limited, and for example, the extending length of the reinforcing portion may be set smaller than the extending length of the pipe body.

In some embodiments, the material of the reinforcing portion is different from the material of the corresponding tube, and the stiffness of the material used for the reinforcing portion is greater than the stiffness of the material used for the corresponding tube. For example, for the center tube 30, the stiffness of the material used for the first reinforcement portion 32 is greater than the stiffness of the material used for the first tube 31. For the main beam pipe 10, the rigidity of the material used for the second reinforcing part is greater than that of the material used for the second pipe body. So configured, it is ensured that the first reinforcement 32 can function to strengthen the center tube 30 and the second reinforcement can function to strengthen the main beam tube 10.

In some embodiments, the first tube 31 is made of metal material, and the first reinforcement portion 32 is made of carbon fiber. The second pipe body is made of metal materials, and the second reinforcing part is made of carbon fibers. Specifically, the first reinforcing portion 32 is disposed on the first tube 31 in a protruding manner, and the second reinforcing portion is disposed on the second tube in a protruding manner. Of course, in other embodiments, the materials of the tube body and the reinforcement portion are not limited.

In other embodiments, the material of the reinforcing portion is the same as the material of the corresponding tube. For example, for the central tube 30, the first reinforcement portion 32 and the first tube body 31 are both made of metal materials, such as aluminum materials. For the main beam 10, the second reinforcement portion and the second pipe body are made of metal materials, such as aluminum.

Further, the reinforcing part and the corresponding pipe body are integrally formed. For the centering pipe 30, the first reinforcement 32 is integrally formed with the first pipe body 31 for easy manufacturing. For the main beam pipe 10, the second reinforcing part and the second pipe body are integrally formed, so that the processing and manufacturing are facilitated.

In some embodiments, the pipe wall of the pipe body with the reinforced part is tightly attached to the reinforced part, and the reinforced part is in smooth transition with the pipe wall of other parts of the pipe body. As for the central tube 30, the first tube body 31 is convexly provided with a tube wall of the first reinforcing portion 32 and closely attached to the first reinforcing portion 32, and the first reinforcing portion 32 and the tube wall of other parts of the first tube body 31 are in smooth transition. Aiming at the main beam pipe 10, the pipe wall of the second pipe body is convexly provided with a second reinforcing part, the pipe wall of the second reinforcing part is tightly attached to the pipe wall of the other part of the second pipe body, and the second reinforcing part is in smooth transition with the pipe wall of the other part of the second pipe body. Thus, potential safety hazards caused by steps between the reinforcing part and the pipe wall of the pipe body are avoided; meanwhile, the pipe walls of the reinforcing part and other parts of the pipe body are in smooth transition, so that the attractiveness can be improved.

In some embodiments, the frame 100 further includes a head tube 40, the head tube 40 is connected to an end of the second tube body remote from the first tube body 31, the head tube 40 is used for mounting a standpipe, the standpipe is used for mounting a handlebar, and the standpipe is connected to a front fork, which is used for mounting a front wheel of a bicycle.

With further continued reference to fig. 1-3, the frame 100 further includes a rear fork 50, the rear fork 50 being coupled to the first tubular body 31 for mounting a rear wheel of the bicycle.

Further, the frame 100 also includes reinforcement tubes and support tubes 60. The first pipe body 31 comprises a first connecting section 33 and a second connecting section 34 which are connected, the first connecting section 33 is connected with the main beam pipe 10 and the five-way pipe 20, and the second connecting section 34 protrudes out of the main beam pipe 10. The reinforcement tube is connected to the main beam tube 10 and the second connecting section 34, and the three form a triangular support structure. One end of the supporting tube 60 is connected with the main beam tube 10, the other end is connected with the five-way tube 20, and the main beam tube 10, the supporting tube 60, the five-way tube 20 and the first connecting section 33 form a triangular supporting structure. The strength of the frame 100 can be improved by the two triangular support structures.

In some embodiments, the head tube 40, main beam tube 10, reinforcement tube, middle tube 30, support tube 60, five-way tube 20, and rear fork 50 are integrally formed. It is contemplated that in other embodiments, welding between the head pipe 40, main beam pipe 10, reinforcement pipe, middle pipe 30, support pipe 60, five-way pipe 20, and rear fork 50 may be provided, and is not limited thereto.
