Abstract
The utility model relates to a bicycle wheel rim, which is made of composite materials. The utility model is provided with a closed outer shell of the wheel rim, and a supporting member is arranged in the outer shell. The supporting member is used for dividing the outer shell of the wheel rim into two areas, the two areas in the outer shell of the wheel rim are hollow, or foaming bodies are arranged in small areas. The supporting member is in the shape of an arched surface or a plane surface. The bicycle wheel rim of the utility model can reduce the weight of the wheel rim and simultaneously enhance the intensity of the wheel rim effectively in order to avoid the deformation of the wheel rim and prolong the service life.
Description
[technical field]
The utility model relates to a kind of wheel rim of cycle wheel.
[background technology]
Automobile, the exploitation of motor bike, though bring the speed and the comfort feature of people's trip aspect, and allow bicycle almost become just student's the vehicle, but because automobile, motor bike is the oil gas of fuel oil and air-blending to be imported in the engine fire, thereby producing power promotes to advance, this has the situation of oil gas incomplete combustion naturally, institute's exhaust gas discharged also can cause the pollution of air simultaneously, though there is the dealer to develop with the automobile of electric power as power, motor bike, but owing to be subjected to the restriction of battery effectiveness, no matter be that horsepower or endurance all can't meet the requirements, and electrically-charged puzzlement is arranged again, therefore can not obtain liking of customer, and the today of advocating environmental protection in countries in the world energetically, add that the modern generally lacks an amount of motion, after the cycle manufacturer merchant constantly researches and develops the high function bicycle of release, more and more many people that has gradually begin to drive bicycle, with walking-replacing tool as short distance, while is each big city city, the world in recent years, all plan the exclusive lane of bicycle, except can reducing the source of pollution, and can obtain the effect of sport and body-building.Known bicycle 1 as shown in Figure 1, be front end at a vehicle frame 11 leader 12 that is pivoted, the handle 12 lower side front fork 13 that is pivoted, should before the 13 lower ends front-wheel 14 that is pivoted again, the rear of vehicle frame 11 trailing wheel 15 that then is pivoted, and the upper shaft of vehicle frame 11 is established a vertical tube 16 between front-wheel 13 and trailing wheel 14, but these vertical tube 16 termination abutment pads 17 install, and install a pedal 18 at front- wheel 14 and 15 of trailing wheels, this pedal 18 can be done the rotation in original place, and pedal 18 also links with transmission component 19 and trailing wheel 15, so after stepping on pedal 19 and rotating, can rotate through transmission component 19 driving trailing wheels 15, rotate synchronously and drive front-wheel 14, to make bicycle 1 reach the purpose of advancing, be metallic material mostly at previous bicycle materials used, though have preferable rigidity intensity, but it is relative, the overall weight of bicycle is also heavier, causes speed significantly to promote, and also is unfavorable for moving simultaneously.And along with the progress of material science, after composite materials such as carbon fiber, glass fibre are developed, each element of existing bicycle, except needs lock the place, can say and can make by composite material, can significantly alleviate the weight of bicycle by this, and but actv. improves the speed of bicycle, again, and for the bicycle of the usefulness of competing for speed, the vehicle body of natural bicycle is lighter, and nature can hoisting speed.And with regard to the structure of wheel 2, shown in Fig. 2,3, all be at the sheathed tire 22 of the outer peripheral face of wheel rim 21 substantially, establish with spoke 23 in wheel rim 21 inner peripheral surfaces again, and platen press moulding in wheel rim 21 utilizes with composite, wheel rim 21 inside then are foaming body 211, alleviate the weight of wheel rim 21 by foaming body 211, but be full of foaming body 211 times in wheel rim 21 inside, also allow weight can't drop to minimum, and its structural strength also weakens, and can promote intensity again so how to effectively reduce the weight of wheel rim 21, and real is the target that current dealer pursues.
[utility model content]
The purpose of this utility model is to provide a kind of bicycle rim, can improve the intensity of wheel rim again when alleviating wheel rim weight.
The utility model provides a kind of bicycle rim, is to make with composite material, has an osed top wheel rim shell, it is characterized in that: establish a support member in this shell, this support member is divided into two zones with the wheel rim enclosure.
Described bicycle rim is characterized in that: two zones in this wheel rim shell can be Openworks shape.
Described bicycle rim is characterized in that: this support member can be divided into large and small two zones with the wheel rim enclosure, can be provided with foaming body in the zonule.
Described bicycle rim is characterized in that: this support member can be an arc surfaced or plane.
Bicycle rim of the present utility model can improve the intensity of wheel rim again in expendable weight.
Be the effect that can be easier to understand structure of the present utility model and can reach, now preferred embodiment explanation of the present utility model as back shown in the conjunction with figs.:

Fig. 1 is the External view of known bicycle.
The External view of the known wheel of Fig. 2.
Fig. 3 is the cutaway view of known wheel rim.
Fig. 4 is the cutaway view of the utility model one preferred embodiment.
Fig. 5 is the cutaway view of another preferred embodiment of the utility model.
Fig. 6 is the block diagram of the another preferred embodiment of the utility model.
[specific embodiment]
At first see also Fig. 4, a kind of bicycle rim 3 of the present utility model, platen press moulding in utilizing with composite material has an osed top wheel rim shell 30, establishes a support member 31 in this shell 30, the arc surfaced that support member 31 can be shown in Fig. 4,5.
This support member 31 is divided into large and small two zones 32,33 with wheel rim shell 30 inside.As shown in Figure 4, in zonule 33, can be provided with foaming body 34.Or as shown in Figure 5, big zone 32 of order and zonule 33 are all a hollow out state, and what support member 31 also can be as shown in Figure 6 again is plane.
The utility model is by establishing a support member 31 in wheel rim 3 inside, thereby the intensity that can actv. improves wheel rim 3, to avoid wheel rim 3 distortion and to prolong the life-span of using, simultaneously, wheel rim 3 forms 32 and one zonule 33, a big zone because of support member 31, owing to be in zonule 33, to establish only with foaming body 34, or be all a hollow out state, and can allow wheel rim 3 commonly use the wheel rim expendable weight, to reduce the overall weight of vehicle body, also can actv. promote the speed when driving, allow the user can improve the advantage of rider tournament, to obtain best contest achievement.
