Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon fiber seat cushion technology, and in particular to a carbon fiber seat cushion with cushioning and shock absorption. Background Technology
[0002] In the field of bicycle and other vehicle seats, the comfort, durability, and lightweight design of seat cushions have always been key research and development priorities. Traditional seat cushion materials, such as foam and sponge, while providing some cushioning, often suffer from deformation and poor durability under prolonged use or high-intensity riding. Furthermore, the base of most seat cushions is made of heavy metal, resulting in an overall weight that hinders lightweight design. Over time, exposure to sunlight and rain can cause corrosion of the metal, leading to safety hazards and insufficient durability of the seat base, thus affecting user safety.
[0003] With the advancement of materials science, carbon fiber, as a lightweight, high-strength, and durable material, has gradually been applied in the field of bicycle saddles. By making carbon fiber saddles, they have the characteristics of being lightweight, safe, and wear-resistant. However, saddles made entirely of carbon fiber can be too hard, causing compression damage to the buttocks during long rides.
[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0016] As a preferred embodiment, the reinforcing rib layer includes at least one reinforcing rib, which is connected to both sides of the inner end of the side guard plate and located in the central area to support the buttocks of the driver and passenger. The reinforcing rib is made by rolling and forming several carbon fiber sheets. The weaving direction of the several carbon fiber sheets includes longitudinal and diagonal weaving. The several carbon fiber sheets are rolled up from bottom to top in the manner of longitudinal weaving, diagonal weaving, diagonal weaving and longitudinal weaving, and the diagonal weaving directions of adjacent vertically adjacent sheets are different.
[0017] The outer surface of the reinforcing rib is also provided with a reinforcing patch, which is set as two carbon fiber patches that cooperate with each other. The left and right sides of the carbon fiber patch have an upper and lower concave-convex structure, and are interlaced with the other patch and wrapped around the outer surface of the reinforcing rib.
[0018] As a preferred embodiment, the buffer and shock-absorbing layer is made of PE foam material, and the PE foam fills the closed space between the protective layer and the support layer.

A reinforcing rib layer 40 and a cushioning and shock absorption layer 50 are also provided between the support layer 10 and the protective layer 20. The cushioning and shock absorption layer 50 fills the gap between the support layer 10 and the protective layer 20 and covers the reinforcing rib layer 40, thereby increasing the cushioning effect, allowing the rider to ride for a long time and relieving buttock compression injuries caused by hard seat cushions.
[0036] In this embodiment, both the support layer 10 and the protective layer 20 are made of carbon fiber plates, which have good rigidity, wear resistance, support and lightweight.

[0041] Specifically, the front end of the protective layer 20 is configured as a narrow front nose, and the rear end is configured as a wide rear nose extending to both sides. The front nose gradually extends backward from front to back to become the rear nose, so as to support the user's buttocks and make it easier for the user to sit on it.
[0042] Furthermore, the protective layer 20 is made of carbon fiber plate formed by stacking at least two carbon fiber sheets. The two carbon fiber sheets are stacked from bottom to top in a longitudinal and transverse manner, and the thickness of each layer of carbon fiber sheet is 0.1mm, and the total thickness of the protective layer 20 is 0.5mm.
[0043] In this embodiment, the side guard plate 30 is made of carbon fiber material and is connected and fixed together with the upper protective layer 20 and the lower support layer 10 by a yarn wrapping process.
[0044] In this embodiment, the reinforcing rib layer 40 includes at least one reinforcing rib, which is connected to both sides of the inner end of the side guard plate 30 and located in the central area to support the buttocks of the driver and passenger.

The several carbon fiber sheets are rolled up from bottom to top in the manner of longitudinal weaving, diagonal weaving, diagonal weaving and longitudinal weaving, and the diagonal weaving directions of adjacent vertically adjacent sheets are different.
[0045] The diagonal routing used in the reinforcing ribs is ±45°. The reinforcing ribs are formed by stacking and rolling them in sequence, which gives them a good support effect. Two reinforcing ribs can be placed alternately within the side guard plate 30 to support the user's buttocks and make them better able to bear the force while riding.
[0046] Reference Appendix Figure 4 As shown: In actual use, a reinforcing patch 60 is provided on the outer surface of the reinforcing rib. The reinforcing patch 60 is set as two carbon fiber patches that cooperate with each other. The left and right sides of the carbon fiber patch have an upper and lower concave-convex structure and are interlaced with the other patch to wrap around the outer surface of the reinforcing rib, so that the reinforcing rib has a better support and protection effect.
[0047] In this embodiment, the buffer and shock-absorbing layer 50 is made of PE foam material, and the PE foam fills the closed space between the protective layer 20 and the support layer 10, thereby achieving a good shock absorption and cushioning effect, allowing users to ride for a long time.
