Description

A carbon fiber seat cushion with both rigidity and toughness

technical field

The utility model relates to the field of bicycles, in particular to a carbon fiber seat cushion.

Background technique

The best carbon fiber seat cushion today, as provided by China Taiwan Announcement No. M241301 "Elastic Seat Cushion Structure for Bicycles", is to install an extension piece that can bounce up and down near the rear end edge under the carbon fiber seat cushion. The extension piece is equipped with two tail seats, which are assembled with one end of the support frame, and the other end of the support frame is fixed under the seat cushion near the front edge by means of the nose seat. , The seat cushion can swing up and down through the extension piece to achieve the function of shock absorption and buffering.

However, when using the above-mentioned structure, when one foot of the rider steps down, it will affect the thigh and buttocks on the corresponding side, so that the half part of the seat cushion will produce sideways resistance. The other foot of the rider lifts up without using force, and this half of the seat cushion will not produce lateral resistance to this side. Therefore, when using a bicycle to pedal, the left and right parts of the seat cushion need to bear asymmetrical resistance. However, the above-mentioned structure cannot relieve the asymmetrical resistance, and is completely inconsistent with ergonomic principles. When the rider pedals for a long time, it not only causes discomfort, but also has the disadvantage of strenuous effort.

In view of this, the present inventor finally completed the present case after many experiments and designs, so as to thoroughly solve the problems existing in the above-mentioned structure.

Utility model content

The purpose of the utility model is to provide a carbon fiber seat cushion with both rigidity and toughness, which conforms to the principles of ergonomics, is comfortable to ride, and saves effort when stepping on it.

In order to achieve the above object, the solution of the present utility model is:

A carbon fiber seat cushion with both rigidity and toughness, including a seat part and a guard part for riding. An elastic bow is set between the nose seat and the tail seat, and the seat plate is set on the bicycle seat tube by means of the elastic bow; In the shape of flat surface, a bonding layer is provided on the bottom surface of the seat part, and the bonding layer is formed by a fiber material impregnated with epoxy resin and a thermoplastic material integrally by mold heat pressing.

The bonding layer has three layers, which are a thermosetting layer, a fiber layer and a thermoplastic layer.

The wall thicknesses of the seat board part and the guard board part are not equal.

After adopting the above-mentioned structure, the utility model forms a joint layer formed by the fiber material impregnated with epoxy resin and the thermoplastic material on the bottom surface of the seat part and is formed by hot pressing of the mold. The rider's legs exert downward pressure on the seat board. Due to the rigidity and toughness of the bonding layer, the seat cushion undergoes moderate deformation. The resistance of the cyclist's legs conforms to the principles of ergonomics, the ride is comfortable, and the pedaling is labor-saving.

Detailed ways

As shown in FIGS. 1 to 5 , the seat cushion 10 is made of carbon fiber material and has a flat surface. The bottom surface is horizontally arranged on the bicycle seat tube through the elastic bow 20 for support.

The seat cushion 10 includes a seat plate portion 11, which provides a ride for the rider. The surrounding side of the seat plate portion 11 is also provided with a guard plate portion 12 whose end is slightly bent downwards, enclosing the seat plate portion 11, and the seat plate portion 11 and the guard plate portion 12 have unequal wall thicknesses to increase their deformation and increase their elasticity. The front edge of the bottom surface of the seat part 11 is also provided with a nose seat 13, and the rear end is adjacent to a tail seat 14, and the nose seat 13 and the tail seat 14 also have slots with opposite openings.

One end of the elastic bow 20 is inserted in the slot of the nose seat 13, and the other end is inserted and fixed in the slot of the tail stock 14, so that the elastic bow 20 can be straddled between the nose seat 13 and the tail stock 14, and the seat cushion 10 can be arranged on the bicycle seat tube by the elastic bow 20 groups that are used for support.

The bonding layer 30 is located on the bottom surface of the seat portion 11. The manufacturing process is as follows: firstly place the fiber layer in the epoxy resin, after the fiber layer absorbs the epoxy resin, the surface is slightly sticky, and then use a mold to place one or more layers A fiber layer is arranged on the bottom surface of the seat part 11 , and a thermoplastic material is superimposed, and then molded into an integral shape by hot pressing with a mold to form the bonding layer 30 . The bonding layer 30 is formed by combining the fiber layer 31 , the thermosetting layer 32 and the thermoplastic layer 33 , and the surface of the formed seat cushion 10 remains flat.

In this way, when the rider sits on the seat cushion 10 with a flat surface and steps on it, since the bottom surface of the seat plate portion 11 has a rigid and tough bonding layer 30, moderate deformation can be made, and the force can be quickly released after the force is released. Reply, it conforms to the principle of ergonomics, the ride is comfortable, and the pedaling is labor-saving.

Referring to Fig. 6, it is a cross-sectional view of another embodiment of the present utility model. In order to increase the deformation of the seat cushion 10, the wall thickness of the seat plate portion 11 and the guard plate portion 12 are set to be unequal, and the seat plate portion 11 is larger than the seat plate portion. The shield portion 12 is slightly thinner.

In summary, the key of the present invention is that the bonding layer 30 on the bottom surface of the seat part 11 is formed by a fiber material impregnated with epoxy resin and a thermoplastic material integrally by mold heat pressing, then when the rider steps on , the rider's legs exert downward pressure on the seat part 11, due to the rigidity and toughness of the bonding layer 30, the seat part 11 produces moderate deformation, and can quickly recover after the force is released, which conforms to ergonomics Principle, comfortable ride, easy pedaling. The foregoing embodiments are only to illustrate the technical ideas of the present utility model, and cannot limit the protection scope of the present utility model with this. Any changes made on the basis of the technical solution according to the technical ideas of the present utility model all fall into the scope of the utility model. within the scope of protection.
