Description

Composite bicycle rim structure with spoke pedestal

The invention relates to a rim structure of a bicycle, in particular to a composite material rim without a tube, and at the same time provides a spoke-connected rim structure.

The bicycle rim mainly rotates the bicycle directly to the ground to advance the vehicle body. The structure generally has a surrounding frame, a hub disposed at a central portion of the circular frame body, and a frame body and a hub disposed between the frame body and the hub. It consists of a number of spokes of true roundness; in the application of materials, it has gradually evolved from an early wooden to a metal frame combined with rubber tires, and the current metal ring combined with composite materials.

The structure between the bicycle rim and the tire can be further divided into two types: "with inner tube" and "tubeless". The "with inner tube" refers to the tire between the rim and the tire. The inner tube inflation degree can adjust the hardness of the tire, which can affect the exertion and grip when riding. The "tubeless" is that the inner tube is not provided between the rim and the tire, and only the rim and the tire are tightly combined. The airtight sealed space is formed, and the hardness of the airtightness can be adjusted by the degree of inflation of the sealed space.

According to the conventional bicycle rim structure of the "with inner tube", the bicycle rim having a reinforcing structure disclosed in the invention patent No. 092114216, the rim has a ring frame structure, and the ring frame structure is compounded. The material is made of: an upper bridge portion; two side walls are connected on both sides of the upper bridge portion, and are surrounded by a tire groove to install tires, and each side wall has an inner side and an outer side The side bridge; the lower bridge portion is connected to the two side walls, and is evenly arranged with a spoke wire hole for the outer end of the spoke wire; the metal reinforcing net is disposed between the inner and outer side surfaces of the two side walls; thereby increasing The tire groove is subjected to the tension of the tire.

A bicycle rim structure that is known as a "tubeless", such as the "bicycle composite rim" disclosed in the domestic patent No. 96100655, which comprises: a rim body having two phases Side walls that are spaced apart from each other and define a tire tight space, and opposite sides thereof are inner peripheral walls that respectively connect inner ring edges of the two side walls and define a spoke assembly space, and are disposed on the two side walls and the inner side wall An intersection of the peripheral wall and a first annular rib wall separating the tire tight space and the spoke splicing space, the inner peripheral wall having a plurality of spaced-apart through holes, and a plurality of concave ridges respectively located between any two adjacent through holes An empty slot, the plurality of through holes and the plurality of recessed hollow slots are connected to the spoke assembly space; and the plurality of lightweight reinforcing panels are different from the rim body and are respectively embedded in the The plurality of recessed hollow slots of the inner peripheral wall of the rim body.

Another conventional bicycle rim structure that is also a "tubeless", such as the domestic The "composite material rim structure" disclosed in the new patent No. 97218351 has an inner ring surface and an outer ring surface, wherein the inner ring surface is connected by a steel wire and a wheel hub, and the outer ring surface is used for a tire wearing sleeve, and its main features are In: the inner ring of the composite material rim is connected with the wire adjusting cap. When the composite material rim is formed, the inner surface is covered with a hard inner lining block, and the inner lining block position can be drilled with the inner screw hole. The block is to withstand the destructive force of the screw hole in the drill and the tension of the wire adjusting cap.

Analysis of the rim structure of the current "tubeless", because the rim and the tire are connected After that, it must be in a confined space to maintain fullness and airtightness when inflated. Therefore, the structural design is more focused on the outer edge of the tire's bead and the outer frame of the rim; on the other hand, the rim material The metal material is also often used, and the structure of the rim can be integrally formed by the drawing process, and then bent into a circle shape, and the spokes are assembled.

In addition to the difference between the inner tube and the inner tube, the bicycle rim is also different in material application. The structural design requirements are also different; the bicycle rim materials commonly available on the market can be roughly classified into "all metal materials" and "metal and composite materials", among which "all metal materials" are drawn with metal materials. The formed rim can be made into a shape according to the shape of the required and the inner wall of the partition; the "metal and composite mixed material" is made of a metal frame made of drawing, and is laminated with a layer. The inner frame portion of the composite material is formed together. The two types of rims also form a stencil groove in the outer frame portion and are connected to the tire to form an inflatable closed space, and the inner frame portion is connected to each spoke.

However, the inner frame of the rim is often required to be assembled with each of the spokes. Drilling or screwing, so as to form a joint portion for the spokes to be connected with other locating elements, such a drilling hole will make the rim frame portion unable to form a closed state, so that a space is separated between the inner and outer frames Fate Separately, the outer frame portion can be kept in a sealed state with the tire, and the inner frame can be drilled as needed.

However, the inner frame portion of the drillable material has its limitations in application. If the inner frame of the composite material (such as carbon fiber) is drilled, the inner frame structure is broken, especially the current bicycle wheel structure. It also tends to be lightweight, and the use of composite material rims is not only lighter, but also has a better cushioning effect of ground impact. It is the best material for bicycle rims, so the industry is aiming for spokes. The structure of the inner frame of the composite material is researched and developed to overcome the problem that the carbon fiber material cannot be drilled.

For the analysis of the above-mentioned second and third conventional patent technologies, both of which belong to the above-mentioned description are "metal and composite mixed materials" and are "tubeless" bicycle rims, wherein the second conventional technology utilizes aluminum extrusion The rim body of the type has a plurality of hollow grooves in the inner frame portion, and the complete rim is completely covered by the lightweight reinforced wall plate of the composite material by heating and gluing in the hollow groove portion, and is required to be covered before the glue is covered. The combination of the spoke assemblies on the rim body is the overall technical feature of the patent. The third conventional patented technology is to embed a hard inner lining block applied with metal or plastic material when forming the inner frame of the composite material, thereby providing a portion capable of drilling a screw hole to solve the problem directly to the composite material. The problem of rupture by direct drilling on the inner frame.

However, the second and third conventional patent technologies still have problems. In the second conventional structure, the lock is assembled, and the lightweight reinforced wall is covered and positioned in the hollow slot. Further, the spoke screw is disposed at the lock head exposed to the inner frame of the rim, but the second conventional structure is prone to the case where the lock head falls into the frame when the spoke is broken for maintenance, and the lightweight reinforcing wall is added. When the plate has been fixed in the hollow groove of the inner frame and cannot be opened, the lock will never be taken out, and the new spoke can not be screwed again. The entire rim must be scrapped and updated, and the repair is quite inconvenient and the cost is extremely high.

The third conventional structure is for inserting the inner liner of the metal when the inner frame portion is pasted and formed, and then inserting the screw into the inner liner portion, and using the metal inner liner to provide the spoke assembly. The part to be connected, however, the inner frame is completely covered with the inner lining when the composite material is formed. Therefore, when the subsequent drilling operation is performed, the inner frame of the coating is still broken, and the composite material is broken or the turtle is broken. crack, Influencing the overall strength of the inner frame; another sub-surface, in order to stably screw the adjusting cap, the inner pad must have a considerable thickness, and if the size is too thin, the stability of the screw setting is affected, so that the inner pad of the metal Must have a thicker height for drilling screw holes, accumulating the weight of all metal liners in the ring, resulting in an increase in the weight of the overall rim, failing to achieve the goal of lightweighting; therefore, the creators of the case provided the above-mentioned conventional problems The rim type of "tubeless" and "metal and composite mixed material", an exposed spoke pedestal structure.

In view of the above, the composite bicycle rim structure with the spoke pedestal of the present invention comprises: a metal frame, which is a frame of metal material, which is separated by a middle partition to form an outward opening. An outer frame body and an inner frame body having a U-shaped opening, the outer frame body is provided with a tire set thereon; a composite material frame is a frame of the composite material, and the inner frame body Connecting and forming a closed hollow portion together with the inner frame body, the inner diameter edge portion of the composite material frame is a bottom portion of the inner frame having a predetermined thickness; and a spoke seat is a metal material seat body, and is manufactured The composite material frame is embedded in the bottom of the inner frame, and has a connecting portion for exposing the composite material frame, and a spoke perforation is arranged on the two sides of the frame body of the composite material frame to provide a The spokes are disposed in the set position; and the spokes of the metal material are simultaneously embedded in the predetermined portion when the composite frame is formed, and the connecting portion is partially exposed, and the connecting portion is partially formed thereon The spokes are perforated for the structure of the spokes to set the position, which is convenient and fast for assembly. Maintenance does not need to dismantle other components and has the effect of simple maintenance and cost, and the inner frame is no longer subjected to any drilling process to maintain its integrity and strength, which can improve the safety of the rim. And the lightweighting effect of the thickness of the sprinkle seat embedded portion is thin, so that the overall structure can be convenient and practical.

The main object of the present invention is to provide a composite bicycle rim structure with a spoke pedestal, which is constructed by simultaneously embedding a spoke seat of a metal material in a predetermined portion when the composite frame is formed, and is partially exposed and laterally The perforated spokes are perforated for the spokes to be placed in place to facilitate assembly and speed.
