Bicycle seat cushion structure integrally formed with skin layer and plastic shell

The present invention relates to a bicycle seat cushion structure integrally formed with a skin layer and a plastic shell seat, which is formed by direct injection molding, thereby achieving diversification of the skin layer selection, increasing the elasticity of the cushion body and reducing the process procedure.

According to the general bicycle seat cushion molding structure, there are many types of structures, such as foam molding, and there is also a structure formed by hot pressing. The former is formed by foaming a skin layer on the outside of a rubber shell to form a Seat cushion; the other hot-pressed structure is on the surface 11 of a rubber shell 1 (as shown in the first figure), after a layer of adhesive is applied, and then a skin layer 2 is attached thereto, followed by heat. Press forming; the above molding structure, in the end, is to be edge climbing, that is, as shown in the first figure, the edge portion 21 of the skin layer 2 must be manually folded in the edge (as shown in the second figure). ), and then fixed by the nail body 22.

In addition to the typical foaming and hot-pressing structure described above, other seat cushion structures also have a thick layer of leather directly formed by hot pressing a mat, but the leather seat cushion is limited by the leather material. The characteristics, usually can not make multiple changes.

By summarizing the structures of the above known seat cushions, it can be found that the following problems generally exist:

1. The combination of the rubber shell and the skin layer must be bonded by means of an adhesive, which is very labor-intensive and labor-intensive.

2. After the molding, it is necessary to carry out the edge climbing treatment, and it must be fixed by means of the nail body, and the labor cost is high.

3, the selection of the skin layer is limited, such as the processing of the leather, the general plastic synthetic material or foamed processing structure, in fact, is completely different, there are restrictions on the selection of materials.

4, the leather seat cushion structure although the touch is better, but because it does not combine the plastic shell, so its elasticity is slightly insufficient.

5, the outer surface of the skin layer of the seat cushion, because the shape of the streamline changes, so the outer surface is not a flat plane, if you want to print the pattern, the printable part is usually limited to a limited flat area. Therefore, there are restrictions on the printing pattern.

In view of the shortcomings of the above-mentioned formulas, the creators of this case have finally completed the bicycle seat cushion structure of this creation after numerous research and improvement, that is, the purpose of this case is to provide a variety of skin material selection, flexibility and process reduction. The bicycle seat cushion structure is used to improve the use of the bicycle seat cushion.

In order to achieve the above-mentioned purpose of the present invention, a bicycle seat cushion structure integrally formed with a skin layer and a plastic shell is provided, which comprises a rubber shell and a skin layer, wherein: the rubber shell is an elastic shell. The body is disposed on the inner bottom side of the skin layer; the skin layer is a skin layer contoured with the rubber shell seat and covers the surface of the rubber shell seat, and is combined with the plastic shell seat by injection molding The structure.

The above-mentioned rubber shell seat is a shell made of a plastic material.

The above-mentioned skin layer is a skin layer of a leather material.

The above-mentioned skin layer is a skin layer synthesized by a plastic material.

The above skin layer is a skin layer of a cloth.

Referring to the third and fourth figures, a bicycle seat cushion 3 structure integrally formed with a skin layer and a plastic shell is provided, which comprises a rubber shell 31 and a skin layer 32, wherein: the shell seat 31, An elastic housing is disposed on the inner bottom side of the skin layer 32. The skin layer 32 is a skin layer that is contoured to the rubber shell seat 31 and covers the surface of the rubber shell seat 31. The plastic shell 31 is a structure in which the injection molding is combined.

The above-mentioned rubber shell seat 31 is a shell made of a plastic material.

The above-mentioned skin layer 32 is a skin layer of a leather material.

The above-mentioned skin layer 32 is a skin layer synthesized by a plastic material.

The skin layer 32 described above is a skin layer of a cloth.

In the bicycle seat cushion 3 of the above structure, the outer surface 321 of the skin layer 32 can be unfolded into a plane before being molded and combined with the rubber shell seat 31, so as to facilitate the color printing on the surface 321 thereof, thereby solving the problem. Limitations of printable parts to provide more pattern printing.

The use of the above-mentioned structure of the creation has the following advantages and advantages:

1. The combination of the plastic shell and the skin layer of the present invention can save manpower and man-hours without the aid of adhesive bonding.

2. It is not necessary to carry out the edge climbing treatment after the creation of the creation, and it is not necessary to fix it by means of the nail body. Moreover, the rubber shell and the skin layer are completely fitted, so that labor costs can be effectively saved.

3. The selection of the skin layer of this creation is not limited. Any material such as leather, general plastic synthetic leather, or cloth can be used as the material for the skin layer.

4, the use of this creation combined with the leather skin layer, the seat cushion can still maintain a better touch, plus the combination of the plastic shell seat, with moderate flexibility, thus enhancing the seat cushion's elasticity.

5, the structure of this creation, can provide some retro type, performance type and other hard bicycle seat cushion, combined with a soft skin layer on the surface of the seat cushion to increase the comfort of riding, and not increase The original size is too large, so that the rider can still maintain the flexibility of its control.

6. The outer surface of the skin layer of the creation can be unfolded into a plane before being molded and combined with the plastic shell to facilitate the color printing of the surface, thereby solving the limitation of the printable part of the formula to provide more elements. The pattern is printed.

In summary, the composition of the seat cushion structure of the present invention can achieve diversification of the material of the skin layer, increase the elasticity of the cushion body, and at the same time save the process of adhesion, nailing and edge climbing of the adhesive; Those who have unique industrial use, novelty and progressive requirements for new patents.

The specific embodiments set forth in the present disclosure are merely for convenience of explanation of the technical content of the present invention, and the present invention is not limited to the above embodiments, and does not exceed the spirit of the present invention and the following patent application scope.
