Description

Bicycle rim structure

The present invention relates to a bicycle rim structure, and in particular to a bicycle rim structure that is structurally stable and lightweight.

The known bicycle wheel structure, as shown in FIG. 10, is a spoke wheel (90), the spoke wheel (90) having a rim (91) and a hub (92), the hub (92) being located at the center of the rim (91) and being radially connected to the hub (92) and the rim (91) by a plurality of thin radials (93), and the plurality of radials (93) are used to keep the spoke wheel (90) in a true circular state as much as possible to maintain smooth rolling and stable rolling.

However, it is not difficult to see that this type of spoke wheel (90) has some disadvantages. First, the combination of the rim (91) and the hub (92) with the spokes (93) increases the complexity and cost of processing. In addition, there are many radially arranged spokes (93). If one of them is damaged, the structure will be unbalanced and unstable. In addition, when the bicycle falls, the spokes (93) will be inserted by the parking posts of other bicycles, making it difficult to lift it up, which may easily cause injuries to the user. The spoke wheel (90) uses thin and long spokes (93) to keep the spoke wheel (90) in a true round state, which can indeed achieve the effect of lightweighting.

In order to meet the demand for structural stability, blade-type wheels have also emerged. However, the conventional blade-type wheels also have disadvantages. Conventional blade-type wheels are completely symmetrical, with a relatively simple structure and poor balance. They are also relatively heavy, and the weight will increase the burden of riding for a long time. Therefore, the problem of lightweighting must be considered while taking into account structural stability.

Therefore, the inventor of this invention took this into consideration and came up with the idea of invention. He then designed it based on his years of experience, conducted many discussions and conducted sample tests, and made many revisions and improvements before launching this invention.

The technical problem that the present invention aims to solve is to provide a bicycle wheel rim structure that is structurally stable and lightweight in view of the above-mentioned deficiencies of the existing technology.

Technical features for solving the problem:

The present invention provides a bicycle wheel structure, which includes a bicycle wheel, wherein the bicycle wheel is integrally formed and has a wheel frame, an axle and a number of V-shaped cutters, the axle is provided in the center of the wheel frame, a number of first extensions and a number of second extensions are extended along the outer circumference of the axle, the number of the first extensions and the second extensions are equal and arranged crosswise and spaced, the first extensions and the second extensions are each provided with a cutter connected to the wheel frame, the bottoms of the first extensions and the second extensions are respectively biased toward the right side and the left side of the wheel frame, the cutters are gradually biased toward the inner middle of the wheel frame, so that the cutters connected to the first extensions and the second extensions are respectively connected to the inner middle of the wheel frame from the right side and the left side, and the axle is provided with an axle hole.

Optionally, the number of the first extension part and the second extension part is two each and they are arranged crosswise and at intervals.

Optionally, the number of the first extension part and the second extension part is three each and they are arranged crosswise and at intervals.

Preferably, the material of the bicycle rim is carbon fiber.

The first main purpose of the present invention is that, since the bicycle rim is formed in one piece, it has better structural strength, is not easily damaged, and reduces the assembly between components, which is helpful in production and use, and can reduce production time and cost.

The second main purpose of the present invention is that the first extension part and the second extension part are equal in number and arranged at cross-intervals, and each of the first extension part and the second extension part is provided with a wheel cutter connected to the wheel frame, and the wheel cutters are gradually inclined toward the inner middle of the wheel frame, so as to achieve the effect of staggered maintenance of structural force balance.

The third main purpose of the present invention is that the wheel cutter is V-shaped, which effectively disperses the contact points with the wheel frame while increasing the structural strength and having the effect of lightweighting.

Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description and the related drawings.
