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 a plurality of spokes, and two lateral ring parts respectively disposed on both sides of the inner rim part, the inner rim frame defining an internal space extending radially from an opening formed between the two lateral ring parts; and

a composite rim body encapsulating the inner rim part and the two lateral ring parts of the inner rim frame, the composite rim body having a first ring segment encapsulating the inner rim part of the inner rim frame, two second ring segments encapsulating the two lateral ring parts of the inner rim frame, a third ring segment having two protrusions and encapsulating terminals of the two lateral ring parts of the inner rim frame, and a supporting part covering the opening of the internal space of the inner rim frame to enclose the internal space defined by the inner rim frame.

2. As the structure of a bicycle wheel rim claimed in claim 1, wherein the composite rim body is an outermost layer, and 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 at least one of aluminum, aluminum alloy, molybdenum chromium alloy, titanium alloy and magnesium alloy.

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

an inner rim frame having an inner rim part corresponding to a plurality of spokes, two lateral ring parts respectively disposed on both sides of the inner rim part, and two hooks respectively disposed at terminals of the two lateral ring parts, the inner rim frame defining an internal space extending radially from an opening formed between the two hooks; and

a composite rim body encapsulating the inner rim part and the two lateral ring parts of the inner rim frame, the composite rim body having a first ring segment encapsulating the inner rim part of the inner rim frame, two second ring segments encapsulating the two lateral ring parts of the inner rim frame, a third ring segment encapsulating terminals of the two hooks of the inner rim frame, and a supporting part covering the opening of the internal space of the inner rim frame to enclose the internal space defined by the inner rim frame.

5. As the structure of a bicycle wheel rim claimed in claim 4, wherein the composite rim body is an outermost layer, and 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 at least one of aluminum, aluminum alloy, molybdenum chromium alloy, titanium alloy and magnesium alloy.

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

an inner rim frame made of a metal material, the inner rim frame having an inner rim part and two lateral ring parts respectively disposed on both sides of the inner rim part, the inner rim frame defining an internal space extending radially from an opening formed between the two lateral ring parts; and

a composite rim body made of a composite material, the composite rim body encapsulating the inner rim part and the two lateral ring parts of the inner rim frame, the composite rim body having a first ring segment encapsulating the inner rim part of the inner rim frame, two second ring segments encapsulating the two lateral ring parts of the inner rim frame, a third ring segment having two protrusions and encapsulating terminals of the two lateral ring parts of the inner rim frame, and a supporting part covering the opening of the internal space of the inner rim frame to enclose the internal space defined by the inner rim frame.

8. As the structure of a bicycle wheel rim claimed in claim 7, wherein the composite rim body is an outermost layer, and the composite material of the composite rim body includes a carbon-fiber composite material.

9. As the structure of a bicycle wheel rim claimed in claim 7, wherein the metal material of the inner rim frame includes at least one of aluminum, aluminum alloy, molybdenum chromium alloy, titanium alloy, and magnesium alloy.
