Description

Technical Field

[0001] This utility model relates to the field of cushion structure technology, specifically a composite material cushion and its bicycle mat. Background Technology

[0002] The common cushion structure in daily life often needs to have both support and softness to achieve the dual requirements of comfort and protection. As a result, the selection of materials and the structural design of such cushions have become very basic research areas in the current related fields.

[0003] Although fiber-reinforced composite materials, through the combination of fiber weaving structures and resin materials, possess excellent rigidity, strength, and impact resistance, effectively compensating for the shortcomings of single materials, their structural rigidity also makes it difficult to develop structures like cushioning materials that simultaneously possess both support and flexibility. Utility Model Content

The bottom surface and the top surface each include a first edge sealing portion and a second edge sealing portion. The bottom surface and the top surface are joined together by the first edge sealing portion and the second edge sealing portion to form a cavity-shaped buffer core portion located between the bottom surface and the top surface. An elastic material is disposed inside the buffer core portion.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Please see Figure 1-2This embodiment provides a composite material pad 10, which includes a bottom surface 11, a buffer sandwich portion 13, and a top surface 12. Both the bottom surface 11 and the top surface 12 are made of fiber-reinforced composite material, and the buffer sandwich portion 13 is disposed between the bottom surface 11 and the top surface 12.

[0022] The fiber-reinforced composite material includes fiber fabric and reinforcing resin. The fiber-reinforced composite material is formed by impregnating the fiber fabric with the reinforcing resin and then curing it to achieve rigidity, strength and impact resistance.

[0023] The fiber fabric may be carbon fiber, glass fiber, metal fiber or other commonly used fiber materials.

[0024] The reinforcing resin may be a thermoplastic resin or a thermosetting resin.

[0025] The bottom surface 11 and the top surface 12 respectively include a first edge sealing portion 111 and a second edge sealing portion 121. The bottom surface 11 and the top surface 12 are combined through the first edge sealing portion 111 and the second edge sealing portion 121. After the combination, a cavity is formed between the bottom surface 11 and the top surface 12. The range of the cavity is further defined as the buffer sandwich portion 13.

[0026] The buffer core 13 protrudes toward the top surface 12, giving the surface of the top surface 12 a non-smooth textured surface.

[0027] The cushioning core 13 contains an elastic material 20, which enables the cushioning core 13 to have elastic deformation and support effects. The elastic material 20 can be a spring, foam, or elastic plastic, and there are no limitations on this.

[0028] Furthermore, the overall area of ​​the buffer sandwich portion 13 covers less than 70% of the area of ​​the bottom surface 12. In this embodiment, the buffer sandwich portion 13 includes a first buffer sandwich portion 131 and a second buffer sandwich portion 132, which are symmetrically disposed at both ends of the composite material pad 10, and the total area of ​​the first buffer sandwich portion 131 and the second buffer sandwich portion 132 covers 70% of the area of ​​the bottom surface 12.

[0029] Furthermore, the bottom surface 11 and the top surface 12 can be made of different fiber-reinforced composite materials. That is, at least one of the fiber fabrics or the reinforcing resins used in the bottom surface 11 and the top surface 12 are different. By using different fiber-reinforced composite materials for the bottom surface 11 and the top surface 12, the bottom surface 11 and the top surface 12 can be selected to have composite material layers with different rigidity strengths according to the requirements.

[0030] Furthermore, the thickness of the bottom surface 11 is greater than the thickness of the top surface 12.

[0031] During the manufacturing process of the composite material pad 10, the bottom surface 11, the elastic material 20 and the top surface 12 are laid in sequence. The first edge sealing part 111 and the second edge sealing part 121 can be bonded to each other by means of adhesive, hot pressing, vacuum hot pressing or high frequency.

[0032] Furthermore, the reinforcing resin of either the bottom surface 11 or the top surface 12 is a thermoplastic resin. Therefore, the first edge sealing portion 111 and the second edge sealing portion 121 can be bonded together by heating and melting the thermoplastic resin through mold hot pressing technology.

[0033] Furthermore, the elastic material 20 can be a plastic foam, and the melting point of the elastic material 20 is lower than that of the aforementioned thermoplastic resin. When the elastic material 20 is stacked with the bottom surface 11 and the top surface 12, at least a portion of the elastic material 20 corresponds to the first sealing portion 111 and the second sealing portion 121. In this way, the first sealing portion 111, the second sealing portion 121, and the elastic material 20 can be bonded together by the hot pressing technology of the mold. This is a conventional operation and will not be described in detail.

[0034] It is worth noting that even when the elastic material 20 is hot-pressed together with the bottom surface 11 and the top surface 12, after molding, the elastic material 20 only corresponds to the partial melting and deformation of the first edge sealing part 111 and the second edge sealing part 121. The elastic material 20 in the remaining parts still exhibits the effect of elastic deformation and support in the buffer sandwich part 13. This is common knowledge and will not be elaborated further.

[0035] The composite material pad 10 provided by this invention can be applied to bicycle saddles. With the top surface 12 facing upward, it supports the user's buttocks, thus achieving a cushioning effect through the cushioning core 13 and the elastic material 20. The bottom surface 11 is connected to the bicycle seat post, which can exhibit excellent structural rigidity.

[0036] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0037] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
