Abstract

The utility model discloses a kind of local reinforcement light weight carbon fibre rims, include a hollow rim body, side is stretched out in the two sides of rim body, two sides and rim body form tire slot, spoke hole is evenly distributed on the rim body inner sidewall, the rim body inner sidewall corresponds to each spoke hole and forms the strengthening course independently thickeied.The utility model is only thickeied in the spoke hole peripheral part of rim body spoke stress, without all thickening the whole circle of spoke hole inner sidewall, does not influence wheel rim intensity, significantly mitigation wheel rim weight, lighter, while saving material, reduces production cost.

Description

A kind of local reinforcement light weight carbon fibre rim

Technical field

The utility model relates to bicycle rim technical field, specially a kind of local reinforcement light weight carbon fibre rim.

Background technique

Cycling is the aerobic outdoor sports to the very useful place of human body, is obtained in developed countries such as America and Europes Extensive to carry out, also the vehicles traditional from our impression become fitness equipment to bicycle, and each manufacturer makes great efforts to change invariably Into product design, manufacturing process manufactures the material of bicycle using better material in the hope of better bicycle, from Steel gradually become aluminium alloy, and to pursue lightweight, in recent years, the even more carbon fibre material of large-scale use valuableness is made Frame.

Existing wheel rim is strength demand needed for reaching installation spoke, as shown in Figure 1 and Figure 2, in 1 ' spoke of rim body The whole circle of the inner sidewall of force part is thickeied, wheel rim weight weight, more using material.

Utility model content

The purpose of this utility model is to provide a kind of mitigation wheel rim weight, save material, reduce the part of production cost Reinforcement light-weighted wheel band, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of local reinforcement light weight carbon fibre rim, Comprising a hollow rim body, side is stretched out in the two sides of rim body, and two sides and rim body form tire slot, described Spoke hole is evenly distributed on rim body inner sidewall, the rim body inner sidewall corresponds to each spoke hole and forms independent thickening Strengthening course.

Preferably, the strengthening course is the round or ellipse thickening layer centered on spoke hole.

Preferably, the reinforcing rib that the strengthening course is evenly distributed on spoke hole four directions by four forms.

Preferably, the thickness of the round or ellipse thickening layer and reinforcing rib be from close to spoke hole thickness it is most thick to Outer extension is gradually thinning, and cross section is smooth camber line.

Compared with prior art, the utility model has the beneficial effects that

The utility model is only thickeied in the spoke hole peripheral part of rim body spoke stress, and not having to will be in spoke hole The whole circle of side wall all thickeies, and does not influence wheel rim intensity, significantly mitigation wheel rim weight, lighter, while saving material, reduces production Cost.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 3, Fig. 4 are please referred to, the utility model provides a kind of technical solution: a kind of local reinforcement light weight carbon fibre rim, Comprising a hollow rim body 1, side 11 is stretched out in the two sides of rim body, and two sides 11 and rim body 1 form tire Slot 10 is evenly distributed with spoke hole 12 on 1 inner sidewall of rim body, and 1 inner sidewall of rim body corresponds to each spoke Hole 12 forms the strengthening course 13 independently thickeied.

The strengthening course 13 is evenly distributed on for the round or ellipse thickening layer centered on spoke hole 12 or by four The thickness of the reinforcing rib composition in 12 four directions of spoke hole, the round or ellipse thickening layer and reinforcing rib is by close to spoke hole Thickness most it is thick extend outwardly it is gradually thinning, cross section be smooth camber line.

In the description of the present invention, it should be understood that term " coaxial ", " bottom ", " one end ", " top ", " in The orientation of the instructions such as portion ", " other end ", "upper", " side ", " top ", "inner", " front ", " center ", " both ends " or position are closed System is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, rather than The device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot It is construed as a limitation of the present invention.

In the present invention unless specifically defined or limited otherwise, term " installation ", " setting ", " connection ", " Gu Calmly ", the terms such as " being screwed on " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integral； It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, can also indirectly connected through an intermediary, it can be with It is the interaction relationship of the connection or two elements inside two elements, unless otherwise restricted clearly, for this field For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
