Problems solved by technology
The bottom plate and the leather cover are made by the injection molding machine, and then combined with a relatively low-level split foam layer to make a finished product; the bottom plate is wiped with glue and the foam layer is pasted, and then wrapped with a leather cover to form a whole; the defects of the prior art It is relatively obvious that although the existing holsters are soft, they have poor weather resistance and wear resistance. For bicycles that are often stored outdoors, the saddle holster is very easy to be damaged, and the saddle needs to be repaired after the holster is damaged. Complete replacement is costly

Embodiment
[0024] As shown in the figure, a saddle that improves the strength of the overall saddle holster provided for this embodiment includes a saddle bottom plate 4, a leather sheath 1 fixedly connected to the edge of the saddle bottom plate, and a seat between the saddle bottom plate and the holster. The foam layer 3 in between is evenly sprayed with a polyurea reinforcement layer 2 on the inner side of the leather sheath 1 preformed by vacuum adsorption. In this example, commercially available polyurea spraying materials and polyurea spraying equipment are used, which can evenly spray on the leather case and produce a layer of equal thickness.
[0025] The thickness of the polyurea reinforcing layer is 0.1-2mm.
[0026] When assembling, the holster is preformed by vacuum adsorption through the processing mold, and the polyurea reinforcement layer is evenly sprayed on the inside of the holster; The edges of the two are sealed, so that the foam expands and expands between the leath...

Abstract
The invention relates to the field of saddles, bicycles or motorbikes or electric vehicles, in particular to a saddle for improving the overall saddle leather sheath strength and a processing processthereof. The saddle comprises a saddle bottom plate, a leather sheath fixedly connected to the edge of the saddle bottom plate and a foaming layer arranged between the saddle bottom plate and the leather sheath. Due to the fact that a polyurea wear-resisting layer is evenly sprayed to the inner side of the leather sheath, polyurea is elastomer matter generated through the reaction of isocyanate components and amino compound components, the elasticity of the leather sheath cannot be damaged, a reinforced protection film is formed on the inner side of the leather sheath, and the overall saddle leather sheath strength is improved.
Description
technical field [0001] The invention relates to a saddle, and relates to the field of bicycles, motorcycles or electric vehicles, in particular to a saddle which improves the strength of the overall saddle leather cover and a processing technology thereof. Background technique [0002] Our country has a large population. Due to the constraints of economic factors, traffic conditions and other factors, most people choose bicycles as a means of transportation during travel. Bicycles are also popular because of their lightness and low price. Our country also Therefore, it is called a bicycle country. [0003] A bicycle, also known as a bicycle or a bicycle, is usually a small land vehicle with two wheels. After a person rides on the vehicle, it is powered by pedals. It is a green and environmentally friendly means of transportation. In mainland China, Taiwan, Singapore, it is usually called "bicycle" or "bicycle"; ) car”; there are many types of bicycles, including single bic...
