Abstract

A structure of a bicycle wheel rim is disclosed. It comprises an inner rim frame and a composite rim body. The inner rim frame is provided with an inner rim part, two lateral ring parts respectively disposed on both sides of the inner rim part, two hooks respectively disposed on terminals of the two lateral ring parts, and an opening formed between the two hooks and having a supporting part. The composite rim body encapsulates the inner rim part, the two lateral rings and the two hooks.

Claims

1. A structure of a bicycle wheel rim, comprising:

an inner rim frame having an inner rim part corresponding to plural spokes, two lateral ring parts respectively disposed on both sides of the inner rim part, and an opening formed between the two lateral ring parts; and

a composite rim body encapsulating the inner rim part and the two lateral rings and having a first ring segment encapsulating the inner rim part, two second ring segments encapsulating the two lateral ring parts, a third ring segment having two protrusions and encapsulating terminals of the two lateral ring parts, and a supporting part disposed on the opening thereof.

2. As the structure of a bicycle wheel rim claimed in claim 1, wherein the composite rim body is made of a carbon-fiber composite material.

3. As the structure of a bicycle wheel rim claimed in claim 1, wherein the inner rim frame is made of a lightweight metal material including aluminum, aluminum alloy, molybdenum chromium alloy, titanium alloy or magnesium alloy.

4. A structure of a bicycle wheel rim, comprising:

an inner rim frame having an inner rim part corresponding to plural spokes, two lateral ring parts respectively disposed on both sides of the inner rim part, two hooks respectively disposed at terminals of the two lateral ring parts, and an opening formed between the two hooks; and

a composite rim body encapsulating the inner rim part and the two lateral rings and having a first ring segment encapsulating the inner rim part, two second ring segments encapsulating the two lateral ring parts, a third ring segment encapsulating terminals of the two hooks, and a supporting part disposed on the opening thereof.

5. As the structure of a bicycle wheel rim claimed in claim 4, wherein the composite rim body is made of a carbon-fiber composite material.

6. As the structure of a bicycle wheel rim claimed in claim 4, wherein the inner rim frame is made of a lightweight metal material including aluminum, aluminum alloy, molybdenum chromium alloy, titanium alloy or magnesium alloy.
