New Description: [New Technology Field] This book is about bicycle rims. More specifically, it refers to the inside of the bottom wall of the body part made of double-mouth material. Sheet-shaped Meng member, a composite bicycle rim that enhances the structural strength and stability of the wall. [Prior Art] • Press, the early custom wheel rims are mostly all metal rims (c〇mplete metal rim), although they can provide heat-resistant and the strong tire receiving parts of the tires, but the weight is too heavy 'not paying for bicycle lightweight The trend is that the market and the industry have gradually moved towards composite materials, especially full carbon fiber rims (cQmpiete resistant (10) based rim). [New content] However, the carbon bodied bicycle rim used for foaming tires on the market has the advantages of light weight, but the structural strength of composite materials such as carbon fiber is less than that of metal materials, resulting in compounding. The body part made of the material, in particular, a plurality of spoke holes are evenly arranged thereon, and the bottom wall portion of the spoke wire and the nut can be assembled and connected, and the position of each spoke hole is easily deformed by the pulling action of the spoke wire. Even the rupture affects the service life and safety of the composite rim, so it is necessary to improve the shortcomings of the structure. The present invention provides a composite bicycle rim structure mainly embedding a ring-shaped gold in the bottom wall portion of the composite body rim.

W M315662 The rim structure provided by this creation can strengthen the bottom wall part by the metal member to be covered, especially the structural strength of each spoke position of the bottom wall, so that it can withstand the strength of the girl. The radial force applied by each spoke wire can further improve the service life and safety of the composite bicycle rim. [Embodiment] f First, please refer to the first and second figures. The composite bicycle rim structure is better. The embodiment mainly includes a composite body made of a hollow ring-shaped rim body 10, and the rim body 1 includes a body portion 1 1 and a tire receiving portion 1 2; the body portion ! The second side: there is a first side wall ill and a second side wall 112, and a bottom wall 1 1 3 is connected to the bottom end of the first side wall 1 1 1 and the second side wall 1 1 2; the tire The two sides of the receiving portion Μ 2 respectively have a first braking surface i 2 邻接 adjacent to the first surface 1 1 and a second braking surface 1 2 2 adjacent to the second side wall 12, and the tire receives Location! 2The inside is covered with a hoop-shaped metal reinforced frame 2〇; please refer to the following: a metal reinforced ring piece 3〇, which is in the form of a ring piece, and can be completely embedded in the body part 11 Inside the bottom wall 113, the reinforced ring piece 30 of the present embodiment may be selected from any metal material such as steel, Ming materials, Ming alloy, chrome-plated alloy, titanium alloy or magnesium alloy, and has a radial section. The system is curved in the direction of the second:: direction arc; more importantly, the metal reinforced ring 30 is a material-extending wall structure, so except for the respective filament holes (not shown) In order to completely close the wall surface, the wall plate is added and has a radial section thickness of M315662, so that the overall structural strength and the strength against radial deformation can increase the entire bottom wall ii is the wire hole position (4) structural strength With the sturdiness, it is sufficient to cope with; the radial force applied is not shown). Furthermore, the composite bicycle rim of the present invention, although the body portion 11 is made of a composite material, is embedded in the bottom wall work 3 before the molding, and a metal reinforced ring piece 3 with high structural strength is embedded. 〇, the position of the 1 1 3 part of the bottom wall, especially the bottom wall 丄丄 3, which is affected by the filaments (not shown), can obtain high structural strength and stability|±, especially Withstand the radial direction, that is, the strength of the direction of the filament light force is greatly improved. Therefore, regarding the body part made of the conventional composite material, the position of each Han silk hole of the straight bottom wall is easily deformed or even broken by the action of the spoke wire. Achieving a satisfactory solution, #然, can also be used to improve the service life and safety of composite bicycle rim products. (4) ί Worth - mentioning that 'this is the main material of the composite bicycle rim,:, is the use of composite materials made of the body part 1 1 bottom wall ii = / Gan into the composite structural strong metal components to enhance The bottom wall 1 ^ 2 position is resistant to deformation and structural strength. Therefore, as long as the body part is made of:: composite material, the creation can be applied. As for the structure of the other parts of the tire receiving part 12, the spirit of the creation is hereby stated. . 1Do not ask 'Also' (4) The comprehensive summary of the case = "This creation has its excellent progress in the _ product towel, the same as the % of domestic and foreign research on this kind of mountain has not found the same structure exists in the pre-synopsis (4) Bei Sha, in the literature, in the first, so that this creation has already met the new patent requirements of M315662, and applied in accordance with the law. As stated above, it is only one of the best practices of this creation that is applicable to the scope of this creation patent. [Simple description of the diagram] Equivalent to the example
