Description

Technical Field

[0001] This utility model relates to the field of bicycle parts technology, and in particular to a carbon fiber bicycle seat. Background Technology

[0002] Bicycle saddles, also known as bicycle seats, are important components that come into direct contact with the human body on a bicycle. They can directly affect riding comfort, efficiency, and even riding health. Carbon fiber bicycle saddles, with their significant lightweight advantage and high rigidity, are a popular choice for high-performance riding.

[0003] Existing technology, such as the utility model with Chinese patent authorization announcement number CN220662701U, discloses a novel carbon fiber saddle, including a buffer pad, a carbon shell, and a carbon bow. The buffer pad is disposed on the upper surface of the carbon shell, and the carbon bow is disposed on the lower surface of the carbon shell to support it. The buffer pad has a side air inlet, and the carbon shell has a central hole and an air-gathering groove. The side air inlet of this utility model provides ventilation and effectively ensures the heat dissipation of the buffer pad surface. The air-gathering groove design on the carbon shell effectively guides air into the side air inlet, and the air is then discharged from the surface of the buffer pad, achieving good ventilation and heat dissipation.

[0004] However, the existing carbon fiber saddles and most carbon fiber bicycle seats on the market lack a good replacement mechanism. Traditional saddle pads are usually permanently bonded to the carbon fiber base plate by gluing or sewing. Once the pads wear out, age, or lose elasticity due to prolonged use, they are difficult to replace. At the same time, the fixed pad design cannot adapt to changing usage needs. For example, in the hot summer, riders want better breathability and heat dissipation on the saddle, while in the colder seasons, they may focus more on heat preservation and comfort. Or, when riders want to try different saddles with different firmness and materials, changing saddles is extremely inconvenient, forcing riders to buy multiple saddles to adapt to different conditions. This is not only costly but also wasteful of resources. Therefore, we propose a carbon fiber bicycle saddle to solve the above problems. Utility Model Content

[0005] The core of this invention lies in the fact that the seat module on the top side of the carbon shell can be quickly installed and removed, solving the problems of poor adaptability, difficulty in convenient seat replacement, high maintenance costs, and inability to meet the dynamic needs of riders in existing carbon fiber bicycle seats. This facilitates the achievement of optimal riding comfort and economic benefits. At the same time, it can effectively fix the seat and has excellent installation reliability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A carbon fiber bicycle seat includes a carbon shell and a carbon bow fixedly disposed at the bottom of the carbon shell. The carbon shell includes a carbon fiber base plate and a central hole opened in the middle of the carbon fiber base plate. A U-shaped head is integrally fixedly disposed on the narrow end side of the carbon fiber base plate near the perineum. A positioning block is disposed on the wide end side of the top surface of the carbon fiber base plate away from the U-shaped head. The top of the carbon fiber base plate is connected to a second seat cushion. A connecting block is provided on the narrow end of the bottom face of the second seat cushion near the perineum. The connecting block has an opening structure on the side facing the positioning block that mates with a U-shaped head. A connecting component is provided on the side of the bottom face of the second seat cushion facing the positioning block. The connecting component includes an installation groove on the bottom face of the second seat cushion and a connecting block fixedly installed inside the installation groove. The positioning block has a through groove structure that mates with the connecting block, and the connecting block is engaged with the positioning block through the through groove structure.

[0008] As a further improvement of this application, the U-shaped head protrudes from the narrow end of the carbon fiber base plate, and the connecting block is sleeved on the outside of the U-shaped head through an internal opening structure.

[0009] As a further improvement of this application, the connecting block includes a plug body, an abutment part is provided at one end of the plug body facing the deep interior of the mounting groove, a limiting protrusion is fixedly provided on the top surface of the plug body, and the limiting protrusion is inclined to one end face facing the opening side of the mounting groove.

[0010] As a further improvement of this application, the inner top surface of the positioning block opening structure is provided with a groove structure that cooperates with the limiting protrusion, and the limiting protrusion is engaged with the positioning block through the groove structure.

[0011] As a further improvement of this application, the abutment part is inclined and forms a bent structure with the plug body, and the bottom end surface of the through groove structure inside the positioning block is provided with an inclined surface that cooperates with the abutment part.

[0012] As a further improvement of this application, the carbon bow is symmetrically distributed at the bottom of the carbon shell, and the carbon shell and the carbon bow are integrally formed by 3D printing.

[0013] As another improvement of this application, a connecting component is provided on the outer surface of the wide end side of the carbon shell, and a baffle assembly is provided on the inner side of the connecting component. The baffle assembly includes a fixing pin fixedly connected inside the connecting component, and a connecting ring that can rotate around the axis of the fixing pin is movably connected to the outer side of the fixing pin. An elastic pressure plate is fixedly connected to the outer surface of the connecting ring, and a groove structure that cooperates with the elastic pressure plate is provided on the outer surface of the second cushion.

[0014] As a further improvement of this application, a first cushion is provided on the outer side of the second cushion, which can replace the second cushion. The first cushion includes a carbon fiber pad and a wind tunnel opened in the middle of the carbon fiber pad. The wind tunnel and the central hole are arranged correspondingly. The top surface of the carbon fiber pad has a uniformly distributed protrusion structure.

[0015] Compared with existing technologies, the advantages of this utility model are: 1. This solution involves setting a connecting block on the narrow end of the bottom surface of the saddle near the perineum. When connecting the first or second saddle to the carbon shell, the U-shaped head is horizontally inserted into the opening structure of the connecting block, so that the connecting block fits onto the outside of the U-shaped head. This allows for quick positioning and connection of the carbon shell and the saddle. By setting the first and second saddles to be interchangeable, they can be used in summer and winter respectively, adapting to the changing needs of cyclists.

[0016] 2. In this solution, when connecting the carbon shell and the seat cushion, the connecting block is horizontally inserted into the positioning block. The abutting part first contacts the inclined surface inside the positioning block. When the limiting protrusion is embedded in the groove structure, the abutting part is limited by the inclined surface, which generates an upward force on the plug body, thereby making the limiting protrusion press tightly in the groove structure to fix the seat cushion and improve the connection reliability. Conversely, when it is necessary to separate the carbon shell and the seat cushion, the protruding end of the plug body is pushed down to separate the limiting protrusion from the positioning block. The seat cushion can then be pushed towards the connecting block to pull out the connecting block from the positioning block. At the same time, the U-shaped head can be pulled out from the connecting block to facilitate the replacement of the seat cushion and the carbon shell. Attached Figure Description

[0019] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0020] First implementation method: Please see Figure 1 and Figure 2 As shown, a carbon fiber bicycle seat includes a carbon shell 1 and a carbon bow 2 fixedly mounted on the bottom of the carbon shell 1. The carbon shell 1 includes a carbon fiber base plate 101 and a central hole 103 opened in the middle of the carbon fiber base plate 101. A U-shaped head 102 is integrally fixedly mounted on the narrow end side of the carbon fiber base plate 101 near the perineum. Specifically, as shown... Figure 2 As shown, the top of the carbon fiber base plate 101 is connected to the second cushion 5. The bottom end face of the second cushion 5 is provided with a connecting block 6 near the narrow end of the perineum. The connecting block 6 has an opening structure on the side face facing the positioning block 3 that cooperates with the U-shaped head 102. The U-shaped head 102 protrudes from the narrow end of the carbon fiber base plate 101. When connecting the carbon shell 1 and the second cushion 5, the U-shaped head 102 is inserted into the opening structure of the connecting block 6, so that the connecting block 6 is sleeved on the outside of the U-shaped head 102, which can position and connect the carbon shell 1 and the second cushion 5. Furthermore, a positioning block 3 is provided on the top surface of the carbon fiber base plate 101 away from the wide end of the U-shaped head 102, and a connecting component 7 is provided on the bottom surface of the second cushion 5 facing the positioning block 3. The connecting component 7 includes a mounting groove 71 formed on the bottom surface of the second cushion 5 and a connecting block 72 fixedly disposed inside the mounting groove 71. Figure 3 and Figure 4 As shown, the positioning block 3 has a through groove structure that cooperates with the connecting block 72, and the connecting block 72 is engaged with the positioning block 3 through the through groove structure. When the carbon shell 1 is connected to the second cushion 5, the connecting block 72 is inserted into the positioning block 3 to further position and connect the carbon shell 1 and the second cushion 5. Combination Figure 5 and Figure 6 As shown, the connecting block 72 includes a plug-in body 721. One end of the plug-in body 721 facing the depth of the mounting groove 71 has an abutment portion 722. The abutment portion 722 is inclined and forms a bent structure with the plug-in body 721. The bottom end face of the through-groove structure inside the positioning block 3 has an inclined surface that mates with the abutment portion 722. Simultaneously, a limiting protrusion 723 is fixedly provided on the top surface of the plug-in body 721, and the limiting protrusion 723 is inclined towards one end face facing the opening side of the mounting groove 71. The positioning block 3 has an opening... The internal top surface of the structure has a groove structure that mates with the limiting protrusion 723, and the limiting protrusion 723 is engaged with the positioning block 3 through the groove structure. When the connecting block 72 is inserted into the positioning block 3, the abutting part 722 first contacts the inclined surface on the inner side of the positioning block 3. When the limiting protrusion 723 is embedded in the groove structure, the abutting part 722 is limited by the inclined surface, which generates an upward force on the plug body 721, thereby making the limiting protrusion 723 press tightly in the groove structure and fix the second cushion 5. Conversely, when it is necessary to separate the carbon shell 1 and the second seat cushion 5, push down the protruding end of the plug body 721 to separate the limiting protrusion 723 from the positioning block 3, and then pull the connecting block 72 out from the positioning block 3 in the direction of the connecting block 6. Specific examples Figure 2 As shown, the carbon bow 2 is symmetrically distributed at the bottom of the carbon shell 1, and the carbon shell 1 and the carbon bow 2 are integrally formed by 3D printing, resulting in higher structural strength and connection stability. Specific examples Figure 1 As shown, a first cushion 4 is provided on the outer side of the second cushion 5, which can replace the second cushion 5. Further, the first cushion 4 includes a carbon fiber pad 401 and a wind tunnel 402 opened in the middle of the carbon fiber pad 401. The wind tunnel 402 is correspondingly arranged with the central hole 103. The central hole 103 and the wind tunnel 402 play a ventilation role. At the same time, the top surface of the carbon fiber pad 401 is evenly distributed with a protrusion structure. The wind flows from the wind tunnel 402 to the surface of the carbon fiber pad 401 and flows out on the surface of the carbon fiber pad 401, improving the heat dissipation effect of the surface of the carbon fiber pad 401. The second cushion 5 can be composed of a combination of a rigid base plate and a foam pad. Working principle: When using this carbon fiber bicycle seat, the first saddle 4 and the second saddle 5 can be used interchangeably. The first saddle 4 and the second saddle 5 are easily interchangeable with the carbon shell 1, allowing for use in summer and winter respectively, adapting to the rider's varied needs. Figure 1 and Figure 2As shown, a connecting block 6 is provided on the narrow end side of the bottom surface of the second seat 5 near the perineum. When connecting the carbon shell 1 and the second seat 5, the U-shaped head 102 is horizontally inserted into the opening structure of the connecting block 6, so that the connecting block 6 is sleeved on the outside of the U-shaped head 102, which can quickly position and connect the carbon shell 1 and the second seat 5. Furthermore, when the U-shaped head 102 is horizontally inserted into the connecting block 6, the connecting block 72 is simultaneously inserted into the positioning block 3, specifically as follows: Figure 5 and Figure 6 As shown, when the plug body 721 is inserted into the positioning block 3, the abutment 722 first contacts the inclined surface inside the positioning block 3. When the limiting protrusion 723 is embedded in the groove structure, the abutment 722 is limited by the inclined surface, generating an upward force on the plug body 721, thereby pressing the limiting protrusion 723 against the groove structure to fix the second cushion 5. Conversely, when it is necessary to separate the carbon shell 1 and the second cushion 5, the protruding end of the plug body 721 is pushed down to separate the limiting protrusion 723 from the positioning block 3. Then, the second cushion 5 can be pushed towards the connecting block 6, separating the U-shaped head 102 from the connecting block 6, and the connecting block 72 can be pulled out from the positioning block 3 for quick replacement of the second cushion 5 or the first cushion 4.

[0021] Second implementation method: Please see Figure 7 and Figure 8 As shown in the figure, in this embodiment, a connecting component 7 is provided on the outer surface of the wide end side of the carbon shell 1, and a baffle component 8 is provided on the inner side of the connecting component 7. The baffle component 8 includes a fixing pin 801 fixedly connected inside the connecting component 7, and a connecting ring 802 that can rotate around the axis of the fixing pin 801 is movably connected to the outer side of the fixing pin 801. An elastic pressure plate 803 is fixedly connected to the outer surface of the connecting ring 802. A groove structure that cooperates with the elastic pressure plate 803 is provided on the outer surface of the second cushion 5. A groove structure that cooperates with the elastic pressure plate 803 is provided on the outer surface of the carbon fiber pad 401. Working principle: In this embodiment, the baffle assembly 8 is symmetrically arranged on the wide end side of the carbon shell 1 facing the connecting block 6. After the second cushion 5 or the first cushion 4 is connected to the carbon shell 1, rotating the connecting ring 802 on the outside of the fixing pin 801 causes the elastic pressure plate 803 to rotate, specifically as follows: Figure 9 As shown, since the elastic pressure plate 803 has an initial elastic force toward the inside of the carbon shell 1, the elastic pressure plate 803 is pressed into the connecting groove 9, which can further position the second cushion 5 or the first cushion 4 and improve the connection reliability between the second cushion 5 or the first cushion 4 and the carbon shell 1.
