Bicycle rim, bicycle wheel and bicycle

Abstract

The invention discloses a bicycle rim, a bicycle wheel and a bicycle, the bicycle rim is provided with an annular tire mounting part for mounting a tire and an annular spoke mounting part for mounting spokes, the annular tire mounting part and the annular spoke mounting part are relatively fixed, N spoke mounting parts which are circumferentially and uniformly arranged at intervals are arranged on the annular spoke mounting part, and N is a natural number greater than 3; the inner circumferential wall of the annular spoke mounting part is arranged in a concave-convex mode in the circumferential direction, N inwards-concave parts and N inwards-convex parts are formed, the concave-convex direction is arranged in the radial direction, the inwards-concave parts are filled with reinforcing bases so that the inner circumferential wall of the annular spoke mounting part can be of a rotation structure, and the spoke mounting part corresponds to the inwards-concave parts in position. The bicycle rim has the advantages that the fixing strength between the spokes and the rim is enhanced through the reinforcing structure, the inner circumferential wall of the annular spoke mounting part is of a rotary structure through the reinforcing seat, the smoothness of the inner circumferential wall of the annular spoke mounting part is improved, and the spokes are avoided from spraining the feet.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to bicycle rims, bicycle wheels and bicycles. Background technique [0002] Existing bicycle rims include two types of stainless steel and carbon fiber rims. Carbon fiber rim is a kind of carbon fiber impregnated with resin to laminate the shape of the rim into the mold (a shape-setting auxiliary tool during the rolling process of the rim) after a period of high-temperature pressurization and solidification ( A process in which the rolled product undergoes high temperature and high pressure in the mold cavity to make it react and shape). Existing bicycle rims, see figure 1 with figure 2 , with a relatively fixed ring-shaped tire mounting portion 1' for mounting tires and a ring-shaped spoke mounting portion 2' for mounting spokes 3', and N (a natural number greater than 3) is provided on the ring-shaped spoke mounting portion 2' Spoke mounting portions 21' arranged at uniform ...

AI Technical Summary

Problems solved by technology

In order to enhance the bonding strength between the spoke 3' and the ring-shaped spoke installation part 2', a reinforcement structure 22' needs to be provided on the inner peripheral wall of the ring-shaped spoke installation part 2' corresponding to the spoke installation part 21', such as CN203267647U, CN208324754U, TWM250823, due to the reinforcement structure, the inner peripheral wall of the annular spoke installation part 2' has a concave-convex structure 4', which is not smooth, which affects the rim wheel, and the spokes are easy to be lame, so there is a need for further improvement
