Problems solved by technology

Because in the existing self-proclaimed wheel rim, the tire joint, the spoke joint, the first side wall and the second side wall are uniformly sealed, so that when the rim rotates when the bicycle is riding, the first side wall on both sides of the rim The area in contact with the second side wall and the air passing through the rim is relatively large, resulting in large air friction resistance due to the rotation of the rim, and the high wind resistance reduces the riding rotation efficiency of the rim

Embodiment 1

[0037] Embodiment 1, a kind of bicycle rim, such as figure 2 , 4 As shown, it includes a ring-shaped tire joint 1 and a spoke joint 2 arranged concentrically at intervals, and a first side wall 3 and a second side wall 4 integrally formed on both sides of the tire joint 1 respectively. The first side wall 3 A first wind resistance channel 5 and a second wind resistance channel 6 are respectively reserved on the second side wall 4, and a plurality of first connecting parts 51 and second connecting parts are arranged at intervals in the first wind resistance channel 5 and the second wind resistance channel 6 respectively. 61 , the first wind resistance passage 5 and the second wind resistance passage 6 are separated by a plurality of first connecting parts 51 and second connecting parts 61 into a plurality of first and second wind resistance holes 52 and 62 spaced apart. Through the arrangement of the first choke hole 52 and the second choke hole 62, the air resistance experie...

Embodiment 2

[0040] Embodiment 2: a kind of bicycle rim, as Figure 8 As shown, the difference between it and Embodiment 1 is that in this embodiment, the two sides of the opening surface of the concave surface of the tire joint part 1 are set as planes. In this embodiment, the first connecting portion 51 and the second connecting portion 61 are fan-shaped plates with the same shape, and the distance between the adjacent first connecting portion 51 and the adjacent second connecting portion 61 is triangular, and the triangular tip Set towards the center of the rim.

[0041] The working process and beneficial effects of the present invention are as follows: when the rim rotates, the airflow generated by the rotation on the first side wall 3 and the second side wall 4 passes through the first wind resistance hole and the second wind resistance hole. Through the cooperative arrangement of the first connecting part 51, the second connecting part 61, the first wind resistance channel 5 and the...

Abstract

The invention discloses a bicycle wheel rim, relates to the technical field of bicycles and solves the technical problem that the rotation efficiency of the wheel rim is reduced because the wheel rimis greatly influenced by wind resistance during rotation. The bicycle wheel rim is characterized by comprising tire joining parts and spoke joining parts which are circularly and concentrically disposed at intervals, and a first side wall and a second side wall which are integrally formed and are respectively located on two sides of the tire joining part; a first wind resistance channel and a second wind resistance channel are respectively reserved in the first side wall and the second side wall; the first wind resistance channel and the second wind resistance channel are circumferentially andcircularly disposed in the first side wall and the second side wall; a plurality of first connecting parts and second connecting parts are respectively, integrally and circumferentially disposed at intervals between the first wind resistance channel and the second wind resistance channel; the first wind resistance channel and the second wind resistance channel are respectively divided into a plurality of first wind resistance holes and second wind resistance holes which are disposed at intervals by the plurality of first connecting parts and second connecting parts. The bicycle wheel rim hasthe advantages that the riding rotation efficiency of the wheel rim is improved.

Description

technical field [0001] The invention relates to the technical field of bicycles, more specifically, it relates to a bicycle wheel rim and a bicycle. Background technique [0002] The Chinese patent that publication number is CN102223784B discloses a kind of rim that is used for the bicycle wheel that has tire, wheel hub and spoke, and described bicycle rim comprises: [0003] the radially outer tire joint; [0004] the radially inner spoke joint; [0005] a first sidewall and a second sidewall spaced apart from the first sidewall, the first sidewall and the second sidewall at the tire junction and the spoke junction extend between; [0006] The tire engaging portion and the spoke engaging portion and the first sidewall and the second sidewall form an annular body, wherein a rim is formed by the rim and the tire mounted on the rim is substantially elliptical in cross-section, and the maximum width of the first and second sidewalls of the rim is arranged closer to the spok...
