Description

Structure of the rim

The present invention relates to a structure of a rim, and more particularly to a rim structure equipped with a composite frame.

According to the conventional bicycle rim structure, as shown in FIGS. 5 and 6, a rim body 30 is included. The rim body 30 has a frame rib 31, and the sides of the frame rib 31 are oppositely extended. The frame wall 32 and the two side frame walls 32 extend inwardly to form a closed inner frame portion 33, and a limiting space 331 is formed therein, and the rim body 30 can also be assembled from the inner inner frame portion 33. There is a composite frame 34, wherein the frame rib 31 and the inner frame portion 33 are oppositely inserted through the through hole 311 and the through hole 332, so that the spoke 35 can be assembled through the through hole 332 and the spoke nut 351, and the spoke nut is assembled. The 351 is inserted into the limiting space 331 by the through hole 311 of the frame rib 31, and then screwed and fixed with the spoke, thereby restraining the spoke nut in the limiting space 331, thereby completing the assembly of the rim.

It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reason is as follows: According to the conventional rim body 30, the inner side of the frame rib 31 is extended by the two side frame walls 32 to form an inner frame. The portion 33 can be restrained in the limiting space 331 when the spoke nut is coupled to the spoke, and the inner tube and the spoke nut are prevented from rubbing and cracked, but the weight of the rim body 30 cannot be effectively reduced, thereby reducing The effect of reducing the weight of the rim body 30, together with the assembly of the composite material frame 34, allows the rim body 30 to have no degradation in quality, which is not practical, and also increases the cost of the structure.

In summary, a lightweight rim structure has been developed on the market. Please refer to Figure 7 for details. The rim body 40 is a single rib aluminum ring, and the overall structure effectively achieves lightweight effects. However, the frame ribs 41 of the rim body 40 and the inner tube space 42 do not have any hidden space, and the attachment of the spokes 43 may cause scratches on the inner tube surface, so that the rim body 40 cannot directly be attached with the spokes by the frame ribs 41. 43. The tension frame 43 can only be positioned by the composite frame 44, but the bottom of the composite frame 44 must be thickened, thereby increasing the weight and cost of the composite frame 44, and greatly reducing the rim body 40. Lightweight effect.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

According to the conventional rim system, the inner side frame portion 32 is extended from the two side frame walls 32 to form an inner frame portion. Although the spoke nut is coupled with the spokes, the inner ring can be restrained from the limit space to prevent the inner tube from rubbing against the spoke nut. However, the rupture of the rim can not effectively reduce the weight of the rim body, thereby reducing the weight reduction effect of the rim, and the assembly of the composite material frame, so that the quality of the rim body does not decrease, and is not practical. This is the technical problem that the creative wants to solve.

Moreover, another conventional rim structure is a single rib aluminum ring. The frame rib of the rim body 40 and the inner tube space have no hidden space, and the installation of the spokes may cause scratches on the inner tube surface, so that the wheel The ring body cannot be directly attached with the spokes by the frame ribs 41, and only the composite material frame 44 can be used for the tensioning and positioning of the spokes, but the bottom of the composite material frame must be thickened, thereby increasing the weight of the composite material frame and The cost greatly reduces the weight reduction effect of the rim body.

Therefore, the present invention provides a structure of a rim, especially a composite assembly material. a rim structure of a frame body, comprising a rim body, the rim body having a base rib portion, and a side frame wall extending correspondingly from both sides of the base rib portion, and defining a inner tube space, and the rim system A plurality of convex bowl portions are formed by pressing from the outer surface of the base rib to the inner surface, and the convex bowl portions are recessed with the receiving recesses corresponding to the inner tube space, and a through hole is formed through the convex bowl portion at the bottom of the receiving recessed portion Moreover, the rim system of the present invention cooperates with the inner surface to cooperate with the composite material frame. With the above structure, the rim can constitute a structure of the rim.

Compared with the effect of the prior art: the rim body has only one base rib on the section, which not only meets the demand for weight reduction, but also the inner side of the rim body is pressed by the base rib to have a plurality of convex bowls And providing a receiving cavity on the outer side of the rim body corresponding to the convex bowl portion, and wearing a through hole, so that the rim body is to be provided with spokes in sequence, the spoke can be directly provided by the through hole Then, by embedding the slot for the embedding restriction of the spoke nut, the inner tube space is still flat, so that the inner tube is assembled and pressurized and inflated, and the spoke nut is not abutted to prevent the inner tube and the spoke nut from rubbing. After the rupture, increase the service life of the inner tube, reduce the replacement rate of the inner tube, and have economic benefits.
