Description

Technical Field

[0001] The invention relates to the technical field of children's bicycle manufacturing, in particular to a manufacturing process of a children's bicycle made of environmentally friendly materials. Background Art

[0002] Children's bicycles refer to bicycles suitable for children aged 1-2 years old, with a maximum saddle height of 100mm to 200mm, and are ridden by a driving mechanism acting on the rear wheel. There are various wheel diameters and styles with or without balance wheels. Children's bicycles cannot be used for road riding; if the size is too large, the child will not be able to hold the handbrake tightly when braking, and the bicycle will not be able to stop. Therefore, it is best to take the child with you to try it when purchasing. In addition, the braking force must not be less than N. Otherwise, the vehicle will not be able to stop, which will cause harm to the child. Some children's bicycles are also equipped with protective wheel balance wheels, which can keep the rider balanced. Therefore, when purchasing, pay attention to whether they are equipped with one on each side, and do not remove them at will when using them. Parents must consider this when purchasing and using them.

[0003] Among them, the "bicycle frame with internal cable routing and its manufacturing method" disclosed in the publication number "CNB" is also an increasingly mature technology, which "includes: positioning a low-friction mandrel adjacent to a flexible mandrel, with a first fiber material present between the low-friction mandrel and the flexible mandrel. The mandrel is wrapped with a second fiber material, and the mandrel is inserted into a mold. The second fiber material is cured to produce a cured component, and the cured component is removed from the mold; and the low-friction mandrel is removed from the cured component to produce an internal passage. The flexible mandrel includes a recess and the positioning step may include inserting the low-friction mandrel into the recess of the flexible mandrel. Preferably, the low-friction mandrel has a cross-sectional shape that substantially matches the cross-sectional shape of the recess. The present invention is also implemented in a portion of a bicycle frame, such as in a portion of the frame during a manufacturing process, and has similar features to those stated above.
