Abstract
Description
Technical Field
[0001] The utility model relates to a shock-absorbing structure, in particular to an innovative structural form of a shock-absorbing seat tube. Background Art
[0002] In view of the fact that traditional bicycle seats are still too rigid and have insufficient shock absorption and cushioning effect in actual use, which causes discomfort to riders, the relevant industry has subsequently developed different types of shock-absorbing seat posts.
[0003] While conventional shock-absorbing seatposts come in a variety of configurations, practical application experience reveals that they still present several challenges and drawbacks that require improvement. For example, riders of varying body shapes inevitably exert varying degrees of pressure on bicycle saddles. Conventional shock-absorbing seatposts are typically designed to handle pressure loads within a specific weight range, resulting in a lack of structural flexibility. Heavy or light riders can easily expose the shock-absorbing seatpost to insufficient or excessive performance. Conventional shock-absorbing seatposts typically utilize a single modular elastic member. Damage requires complete replacement, rather than individual component replacements, resulting in relatively high repair costs. Utility Model Content
[0004] The main purpose of the present invention is to provide a shock-absorbing seat post. The technical problem it aims to solve is how to develop a new shock-absorbing seat post structure that is more ideal and practical and to make an innovative breakthrough.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A shock-absorbing seat tube includes a connecting rod component and an elastic assembly, wherein the connecting rod component includes linkage joints distributed at four corners and relatively define a accommodating space of variable size. The elastic assembly includes two mutually embedded arched elastic blocks, each arched elastic block including a first arched end and a second arched end; a ventral concave side and a dorsal convex side are provided between the first and second arched ends, wherein the first arched end of one arched elastic block is in an embedded state with the ventral concave side of the other arched elastic block, and the two arched elastic blocks are embedded together in the accommodating space in this embedded state; a matching limiting component is formed between the two arched elastic blocks and the accommodating space to prevent the two arched elastic blocks from falling out of the state of being embedded in the accommodating space.
[0007] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:
[0008] The two arched elastic blocks utilize local interlocking friction, mutual compression, and elastic return to achieve optimal shock absorption and cushioning. Furthermore, because the two arched elastic blocks are detachable components, they can be replaced individually if damaged, reducing operating costs. Since the two arched elastic blocks only experience local friction, their flexibility and deformation are enhanced, resulting in a longer and more durable component. Furthermore, by matching the two arched elastic blocks with different density materials, customized shock absorption can be achieved. The overall design demonstrates practical advancements and excellent industrial applicability.
[0009] Another purpose of this invention is to form a plurality of shock-absorbing holes and grooves on each arched elastic block. The shock-absorbing holes and grooves are another technical feature that penetrates the concave ventral side and the convex dorsal side. When the arched elastic block is squeezed and deformed, its deformed structural part can have more directions of displacement, thereby making the arched elastic block have a more comfortable elastic effect and practical progress.
[0010] Another purpose of the present invention is to further strengthen the fitting state of the two arched elastic blocks by forming an embedding concave portion on the concave side of the arched elastic block so that the first arched end of the corresponding other arched elastic block is formed with a matching embedding convex portion, thereby achieving the advantage and practical progress of effectively preventing them from easily escaping from the accommodating space and causing damage and danger.
[0011] Another purpose of the present invention is to further achieve the effect of mutual suppression and practical improvement by further partially extending the second arched end of one of the arched elastic blocks to form a pressing rib to press on the convex side of the other arched elastic block.

[0017] See also Figures 1 to 5The figure shows a preferred embodiment of the shock-absorbing seat tube of the present invention. However, these embodiments are for illustration purposes only and the patent application is not limited to this structure.
[0018] The shock-absorbing seat tube includes a connecting rod member 10 and an elastic component (symbol omitted), wherein the connecting rod member 10 includes linkage joints 11 distributed at four corners and relatively defining a accommodating space 12 of variable size. The elastic component includes two mutually embedded arched elastic blocks 20 and 20B, each of which includes a first arched end 21 and a second arched end 22; a concave side 22 is provided between the first arched end 21 and the second arched end 22. 3 and a dorsal convex side 24, so that the first arched end 21 of one arched elastic block 20 is in an engaged state with the ventral concave side 23 of the other arched elastic block 20B, and the two arched elastic blocks 20 and 20B are then embedded together in the accommodating space 12 in the engaged state; and a matching limiting component 30 is formed between the two arched elastic blocks 20 and 20B and the accommodating space 12, so that the state of the two arched elastic blocks 20 and 20B embedded in the accommodating space 12 reaches a limit and does not fall out.
[0019] like Figure 2 and Figure 3 As shown, in this example, each arched elastic block 20, 20B further has at least one shock-absorbing slot 40. Furthermore, at least one shock-absorbing slot 40 extends through the concave ventral side 23 and the convex dorsal side 24. (Note: The shock-absorbing slot 40 can also be a groove.) The benefit of providing the shock-absorbing slot 40 in this example is that it provides space for the structure to contract when the arched elastic block 20, 20B is squeezed and deformed. In other words, it allows the arched elastic block 20, 20B to achieve a more comfortable elastic effect.
[0020] like Figure 2 and Figure 4 As shown, in this example, the concave side 23 of the arched elastic block 20 is further formed with an embedded concave portion 235, so that the first arched end 21 of the corresponding other arched elastic block 20B is formed with a matching embedded convex portion 215, and the positions of the embedded concave portion 235 and the embedded convex portion 215 correspond to the position of at least one shock-absorbing hole groove 40 (such as Figure 3 As shown, when the arched elastic blocks 20 and 20B are compressed and deformed, the protruding portions 215 deform and squeeze into the shock-absorbing slots 40, increasing their elasticity and softness, thereby achieving a better cushioning and shock-absorbing effect. In this example, the recessed portions 235 and the protruding portions 215 strengthen the engagement of the two arched elastic blocks 20 and 20B, effectively preventing them from easily falling out of the accommodating space 12 and causing damage and danger.
[0021] like Figure 4As shown, in this example, the limiting member 30 includes a flange 31 and a groove 32 that fit together. The flange 31 is formed on the convex side 24 and extends to the second curved end 22, while the groove 32 is formed in a corresponding portion of the accommodating space 12. In this example, the convex side 24 is defined by two side edges 245, so that the flange 31 is formed in a local section in the middle between the two side edges 245.
[0022] like Figure 2 As shown, in this example, the second curved end 22 of one of the arched elastic blocks 20 further partially extends to form a pressing rib 50 for pressing against the convex side 24 of the other arched elastic block 20B. (Note: In this example, both arched elastic blocks 20 and 20B are formed with pressing ribs 50 to achieve a mutually pressing effect.)
[0023] Through the above structural composition and technical features, the practical application of the shock-absorbing seat tube of the utility model is as follows Figure 1 As shown in the figure, it is usually used as a shock-absorbing seat tube under the bicycle seat. Figure 5 As shown, when a user rides on the bicycle seat, generating a downward pressure force 60, the parallelogram-shaped interlocking joints 11 change, causing the size of the accommodating space 12 to twist toward a flat shape. At this point, the two arched elastic blocks 20 and 20B, which are interlocked and embedded in the accommodating space 12, each experience unidirectional compression and deformation. Because the two arched elastic blocks 20 and 20B are both made of elastic materials, they accumulate a relative restoring force when compressed, thus creating a cushioning and shock-absorbing effect, providing the rider with a better and more comfortable ride. Furthermore, because the two arched elastic blocks 20 and 20B are separable components and can be replaced individually if damaged, they have the advantage of reducing operating costs. Furthermore, since the two arched elastic blocks 20 and 20B only experience local friction, their flexibility and deformation are improved, resulting in a longer and more durable component life.
[0024] The two arched elastic blocks 20 and 20B can be made of the same material density or different materials. In other words, if the two arched elastic blocks 20 and 20B are made of different materials density, the industry can accurately classify the load according to the user's weight. For example, the industry can classify the two arched elastic blocks 20 and 20B into three hardness levels: A, B, and C. This allows the matching of the two arched elastic blocks 20 and 20B to be further subdivided into different load conditions such as AA, AB, AC, BB, and so on. This will further facilitate the industry's ultimate goal of customizing shock absorption and cushioning effects.
[0025] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
