Problems solved by technology

[0004] A rim with a fixed inner diameter and outer diameter cannot generate additional moment of inertia when rotating. Therefore, in special cases, such as in the process of standing still and about to start, it will not be able to provide additional power to assist the rider to accelerate
[0005] In view of the fact that the bicycle rim in the background technology cannot provide additional power, the inventor tried his best to find a design for the bicycle rim, hoping to meet the needs of riders

Embodiment Construction

[0032] Regarding the technology, means and effects used in the present invention, a preferred embodiment is given and described in detail below with drawings, which are for illustration purposes only, and are not limited by this structure in the patent application.

[0033] refer to figure 1 and figure 2 , is a three-dimensional appearance view and a side view of the bicycle rim 100 of the present invention. The bicycle rim 100 is made of carbon fiber and includes a body 1 , which surrounds a rotation axis L and has an outer periphery 10 and an inner periphery 20 . There is a constant outer diameter R between the outer peripheral edge 10 and the rotation axis L. As shown in FIG. The inner periphery 20 has unequal inner diameters and has a first portion 21 and a second portion 22 . The first part 21 has a first end 211 and a second end 212, the second part 22 has a first end 221 and a second end 222, and the first end 221 of the second part 22 is connected to the first end ...

Abstract

The invention provides a bicycle rim, which comprises an outer circumference and an inner circumference, wherein the outer circumference surrounds a rotating shaft; a fixed outer diameter exists between the outer circumference and the rotating shaft; the inner circumference is provided with a first position; and the first position is provided with unequal inner diameters. Additional torsional force is generated under the gravity of the first position for assisting a rider in completing a starting process. In a riding process, a moment of inertia is generated at the first position, and can be transmitted to the rider through a vehicle body.

Description

technical field [0001] The invention relates to a structure of a bicycle rim, in particular to a bicycle rim with unequal inner diameters. Background technique [0002] Bicycle development has become a very common means of transportation. Since bicycles are mainly driven by manpower, whether it is acceleration, deceleration, steering or body balance during riding, they are directly controlled by the rider. The conditions of the road surface and the use of body parts are directly transmitted to the rider, so even the slightest changes can be deeply felt by the rider. Therefore, various manufacturers are all committed to improving the parts of the bicycle, so that the rider can ride the bicycle more easily and comfortably. [0003] Among the components of a bicycle, the rim plays an important role in supporting the tire. Referring to the US Patent No. 5,975,645 "Carbon Bodied Bicycle Rim", the existing rim has a carbon fiber frame and a carbon fiber frame Aluminum frame. Th...
