Bicycles, also known as bicycles or bicycles, are usually two-wheeled small land vehicles, which are environment-friendly vehicles powered by pedaling after people ride on the bicycle. In china, taiwan, singapore, commonly referred to as "bicycle" or "pedal cycle"; it is commonly called "bicycle" in hong and ao, china (its cantonese is commonly called as such); and in Japan, called "self-carriage"; the bicycle is of various types, including single-person bicycles, double-person bicycles and multi-person bicycles.
The bicycle is one of the most successful human-powered machines invented by human beings, is a complex machine consisting of a plurality of simple machines, and has higher and higher requirements on the research and development and technical speciality of bicycle products along with the development of the society.
The saddle is an essential part mounted on the bicycle seat tube to provide sitting support. However, currently, in the field of bicycles, motorcycles or electric vehicles, when the saddle adopts the existing structure, the technology of the saddle is similar to that of a common saddle, and only a PVC leather sheath is adopted to replace artificial leather. Manufacturing a bottom plate and a leather sleeve by an injection molding machine, and then matching with a split foaming layer with relatively low comfort level to manufacture a finished product; the floor board eraser glue is stuck with the foaming layer and then wrapped by the leather sheath to form a whole; the defects of the prior art are relatively obvious, the existing leather sheath is soft, but has poor weather resistance and wear resistance, the saddle leather sheath is very easy to damage for a bicycle which is often stored outdoors, and the whole saddle needs to be replaced after the leather sheath is damaged, so that the cost is very high.

The thickness of the polyurea reinforcing layer is 0.1-2 mm.
A process for making a saddle as claimed in, comprising the steps of:
f1: firstly, performing vacuum adsorption on a leather sheath through a processing mould, and uniformly spraying a polyurea reinforcing layer on the inner side of the leather sheath;
f2: foaming is filled on the inner side of the leather sheath, the bottom plate is tightly pressed on the leather sheath through the processing die, the edges of the bottom plate and the leather sheath are sealed, and the foaming layer is formed finally between the leather sheath and the bottom plate, wherein the foaming layer is uniformly sprayed with the polyurea reinforcing layer on the inner side of the leather sheath, and the bottom plate is expanded;
f3: the leather sheath is fixed with the edge of the saddle bottom plate, and the finished product is finished.
The machining die comprises a base and a buckling plate hinged to the base, a containing cavity is formed in the base, a vacuum containing cavity matched with the three-dimensional shape of the saddle is nested in the containing cavity, the edge of the containing cavity is sealed with the edge of the vacuum containing cavity, a plurality of air holes are formed in the vacuum containing cavity, the containing cavity is connected with a vacuum pipeline, a fixing frame for fixedly clamping a saddle supporting frame at the lower part of the saddle is arranged on the buckling plate, and the buckling plate is buckled on the base and is compressed and fixed through a compressing device.
The invention has the beneficial effects that:
because the polyurea reinforcing layer is uniformly sprayed on the inner side of the leather sheath, the polyurea is an elastomer substance generated by the reaction of the isocyanate component and the amino compound component, the elasticity of the leather sheath cannot be damaged, and the reinforced protective film is formed on the inner side of the leather sheath, so that the strength of the whole saddle leather sheath is improved.
