Bicycle frame

Abstract

The invention provides a bicycle frame. Bamboo is cut into strip-shaped pieces which are mainly glued to manufacture a bamboo material, the bamboo material is manufactured into a pipe body, both end heads of the pipe body are fixedly connected with a connecting piece respectively, and then connected with connectors made of relative metal or composite materials to form the bicycle frame; because the strength, toughness and vibration absorption performance of the bamboo material are quite good, and bamboo is also quite light, under conditions of ensuring the firmness and functionality of the bicycle frame, the manufacturing cost can be lowered, the problems of recovery and pollution are solved; moreover, the pipe body can be turned into different shapes as required, so that the width of design is improved.

Description

Technical field: [0001] The invention relates to a modification of the tube body on the bicycle frame, which replaces the original metal or composite material by virtue of the good strength, toughness and shock absorption of the bamboo itself and the characteristics of light material, and the two ends of the bamboo tube body A connecting piece is respectively fixed on the head, so that the connection with the corresponding material is connected to form a vehicle frame. Background technique: [0002] With the progress of industrial and commercial society, various means of transportation have been developed to provide people with more comfortable use. However, with the development and convenience, it has also caused various negative problems such as air pollution, over-exploitation of ore, and rapid reduction of energy. These negative problems are urgently needed to be faced and resolved by people. Therefore, there are more and more countries to expand and promote the use of ...

Problems solved by technology

In addition, ore takes tens of thousands of years to form, and over-exploitation has caused a crisis of ore depletion, so people have been looking for alternative materials for ore. Although recycling can reduce mining, the cost of recycling is not only high also has the problem of pollution

Please refer to Fig. 1, the frame 1 of the known bicycle is composed of a pipe body 11 formed of metal or composite material and a connecting component 12 such as a three-way pipe. They are all made of metal or composite materials. With the increasing demand, the prices of various metals have been rising, which indirectly leads to a relative increase in the unit price of bicycles, which will create an invisible economy for those who want to buy. Although composite materials can be recycled, they cannot be reprocessed into pipe bodies, but can only be used as other lower-demand finished products, and whether metal or composite materials are recycled, there is also the problem of pollution

In addition, as shown in Fig. 2, there have been operators who directly cut the bamboo with appropriate outer diameter to the desired size to form the pipe body 21, and then combined with the connecting component 22 to form a vehicle frame 2. However, because the bamboo is separated by a small interval The length is long and knotted, which makes the appearance poor and not very straight, so that more labor and time must be wasted in the selection of materials, resulting in an increase in cost, so it is not an appropriate material, and its The shape of the tube body 21 is limited to a circular body, so that its design is constrained, so that the scope of the design is reduced, and it is obviously necessary to solve it
