Description

Technical Field

[0001] This utility model relates to the field of bicycle accessory technology, and more particularly to a bicycle linkage shock absorption device applied to a bicycle seat or handlebars, providing good cushioning and shock absorption effects, making the bicycle ride more comfortable for riders. Background Technology

[0002] Bicycles are a widely used mode of transportation. They are powered by human pedaling and do not require electricity or gasoline, making them highly environmentally friendly and ideal for use as a general means of transportation or a recreational activity.

[0003] Given the current road conditions, there are very few completely flat roads. When cyclists encounter rough and uneven roads, or ride on dirt roads, rocky roads, or roads with elevation differences, the bicycle will vibrate due to the uneven ground. To solve this problem, most bicycles are equipped with shock absorption devices to absorb the vibration and make the ride more comfortable for the rider.

[0004] Most shock absorbers are installed on the handlebars, front fork, rear fork, and seat post under the saddle of a bicycle. Existing shock absorber seat posts typically consist of an inner tube, an outer tube, and a spring. The top of the inner tube is connected to the saddle. The outer tube is fitted over the inner tube, and its bottom is connected to the frame. The spring passes through the outer tube and rests against both the inner and outer tubes at its two ends, thereby providing cushioning force to the inner tube. There is a slight gap between the outer and inner tubes, which allows the outer tube to restrict the axial movement of the inner tube and reduces friction between them.

[0005] However, the vibrations generated when a bicycle is in motion are not all axial forces, but inevitably produce some forward and backward components. These components may cause the inner tube to press against the outer tube, and the frictional resistance between the inner and outer tubes will result in poor cushioning and shock absorption. In addition, after long-term use, the tube walls will wear out severely, increasing the gap between the inner and outer tubes. This will cause the outer tube to be unable to effectively restrict the axial movement of the inner tube, allowing the inner tube to sway back and forth in the outer tube. In the absence of cushioning and shock absorption, this may also cause the saddle to shake.

[0006] Therefore, many seat post shock absorption structures have appeared on the market, such as Taiwan Patent Publication Nos. M528906, M250849, M250851, and M610848. The above-mentioned existing patents all use multiple connecting rod seats to connect between the seat cushion and the seat post, and then use an elastic component to be obliquely arranged between the seat cushion and the seat post, and provide elastic force for the connecting rod seats to swing and return, and absorb shock force with the help of the elastic component to achieve the shock absorption effect; however, all of the above-mentioned existing patents have the defect of not being able to effectively compress the elastic component. Utility Model Content

[0007] The technical problem to be solved by this utility model embodiment is to provide a linkage shock absorption device for bicycles, which is applied to the saddle or handlebars of bicycles to provide good cushioning and shock absorption effects, making it more comfortable for riders to ride bicycles.

[0008] To solve the above-mentioned technical problems, the present invention first provides the following technical solution: a linkage shock absorber for bicycles, installed between the seat post and the saddle, comprising at least:

[0009] The first seat body is used to pivotally connect the seat cushion, and has a front upper pivot end and a rear upper pivot end on its front and rear sides, respectively;

[0010] The second seat body is fitted onto the seat tube, and has a front lower pivot end and a rear lower pivot end on its front and rear sides, respectively.

[0011] The first connecting rod seat is located at the front end of the seat tube and is pivotally connected between the upper front pivot end and the lower front pivot end.

[0012] The second connecting rod seat is located at the rear end of the seat tube and is pivotally connected between the upper rear pivot end and the lower rear pivot end, forming a covering space between the first seat body, the second seat body, and the first connecting rod seat; and

[0013] A buffer assembly is disposed within the enclosed space and abuts against the first seat, the second seat, and the first connecting rod seat.

[0014] Furthermore, the first linkage seat has two first linkage portions and a first bridging portion connecting the two first linkage portions. The front and rear ends of the two first linkage portions are respectively pivotally connected to the front lower pivot end and the front upper pivot end. The second linkage seat has two second linkage portions and a second bridging portion connecting the two second linkage portions. The front and rear ends of the two second linkage portions are respectively pivotally connected to the rear lower pivot end and the rear upper pivot end. The upper end of the rear lower pivot end of the second seat extends toward the first seat to form an abutment portion. The abutment portion covers the second bridging portion. The covering space is located between the first seat, the abutment portion, the second seat, and the first bridging portion.

[0015] Furthermore, this utility model embodiment also provides the following technical solution: a linkage shock absorber for bicycles, installed between the handlebar seat and the seat tube, comprising at least:

[0016] The first seat is disposed on the handlebar seat, and has a front upper pivot end and a front lower pivot end on its upper and lower sides, respectively.

[0017] The second body is disposed on the riser seat, and has a rear upper pivot end and a rear lower pivot end on its upper and lower sides, respectively.

[0018] The first connecting rod seat is pivotally connected between the front upper pivot end and the rear upper pivot end;

[0019] The second connecting rod seat is pivotally connected between the front lower pivot end and the rear lower pivot end, and a covering space is formed between the first seat body, the second seat body, and the first connecting rod seat; and

[0020] A buffer assembly is disposed within the enclosed space and abuts against the first seat, the second seat, and the first connecting rod seat.

[0021] Furthermore, the first linkage seat has two first linkage portions and a first bridging portion connecting the two first linkage portions. The front and rear ends of the two first linkage portions are respectively pivotally disposed between the front upper pivot end and the rear upper pivot end. The second linkage seat has two second linkage portions and a second bridging portion connecting the two second linkage portions. The front and rear ends of the second linkage portions are respectively pivotally disposed between the front lower pivot end and the rear lower pivot end. The front end of the rear lower pivot end of the second seat extends toward the first seat to form an abutment portion. The abutment portion covers the second bridging portion. The covering space is located between the first seat, the abutment portion, the second seat, and the first bridging portion.

[0022] Furthermore, the connecting rod damping device is further provided with an adjustment component, which is located on the buffer assembly and is used to adjust the tightness of the contact between the buffer assembly and the first seat, the second seat and the first connecting rod seat in the enclosed space.

[0023] Furthermore, the buffer assembly is a block-shaped shock absorber or a spring that can elastically return to its original position.

[0024] Furthermore, the first connecting rod seat and the second connecting rod seat are connected to the first seat body and the second seat body respectively by a shaft column, a locking screw or a single-sided fixing screw.

[0025] After adopting the above technical solution, the present utility model embodiment has at least the following beneficial effects: When the bicycle linkage shock absorber provided in the present utility model embodiment is installed between the seat post and the saddle, when the rider rides the bicycle and vibration occurs, the second seat body will be linked to the vibrating saddle, thereby causing the first linkage seat and the second linkage seat to move relative to the first seat body and the second seat body, so that the second seat body can swing relative to the first seat body to press against the buffer component assembled in the enclosing space formed between the first seat body, the second seat body and the first linkage seat, and the buffer component absorbs the vibration. The vibration force is transmitted to the saddle via the first and second linkage seats to achieve shock absorption. When the linkage shock absorption device of the bicycle provided in this embodiment is installed between the handlebar seat and the seat tube seat, when the rider rides the bicycle and vibration occurs, the fork seat tube will drive the seat tube seat to move up and down. At this time, the first and second linkage seats will press against the buffer component when they shake. The buffer component will buffer and absorb the vibration force received by the fork seat tube, so that the vibration of the handlebar seat and handlebars can be minimized, thereby effectively reducing the discomfort of riding.

[0033] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present utility model and are not intended to limit the present utility model. Moreover, the embodiments and features in the embodiments of the present application can be combined with each other unless otherwise specified.

[0034] Please see Figure 1 and Figure 2 As shown, an optional embodiment of this utility model relates to a linkage damping device for a bicycle, which is installed between the seat post and the saddle. The linkage damping device includes at least: a first seat body 20, a second seat body 30, a first linkage seat 40, a second linkage seat 50, and a buffer assembly.

[0035] The first seat 20 is used to pivotally attach a bicycle saddle (not shown). The first seat 20 includes a seat bow clamping part 201. The seat bow clamping part 201 is used to clamp a set of seat bows 11 of the saddle. The front and rear sides of the first seat 20 have a front upper pivot end 21 and a rear upper pivot end 22, respectively. Both the front upper pivot end 21 and the rear upper pivot end 22 are provided with through holes or screw holes.

[0036] The seat tube has a tube body 12, and the second seat body 30 is sleeved on the tube body 12 of the seat tube. The second seat body 30 has a front lower pivot end 31 and a rear lower pivot end 32. Both the front lower pivot end 31 and the rear lower pivot end 32 are provided with through holes or screw holes.

[0037] The first connecting rod seat 40 is located at the front end of the tube body 12 of the seat tube and is pivotally connected between the front upper pivot end 21 and the front lower pivot end 31; the second connecting rod seat 50 is located at the rear end of the tube body 12 of the seat tube and is pivotally connected between the rear upper pivot end 22 and the rear lower pivot end 32; please also refer to Figure 3As shown, the first connecting rod seat 40 and the second connecting rod seat 50 are connected to the first seat 20 and the second seat 30 respectively through a through hole via a shaft post 71. Additionally, bushings (not shown) are respectively disposed on both sides of the shaft post 71 passing through the first seat 20 and the second seat 30, allowing the first connecting rod seat 40 and the second connecting rod seat 50 to rotate movably relative to the first seat 20 and the second seat 30 around the shaft post 71. Alternatively, the first connecting rod seat 40 and the second connecting rod seat 50 can also be connected to the first seat 20 and the second seat 30 via a locking screw or a single-sided fixing screw passing through a screw hole.

[0038] like Figures 1 to 3 In the illustrated embodiment, the first connecting rod seat 40 has two first connecting rod portions 41 and a first bridging portion 42 connecting the two first connecting rod portions 41. The front and rear ends of the two first connecting rod portions 41 are respectively pivotally connected to the front upper pivot end 21 and the front lower pivot end 31. The second connecting rod seat 50 has two second connecting rod portions 51 and a second bridging portion 52 connecting the two second connecting rod portions 51. The front and rear ends of the two second connecting rod portions 51 are respectively pivotally connected to the rear upper pivot end 22 and the rear lower pivot end 32. The upper end of the rear lower pivot end 32 of the second seat 30 extends toward the first seat 20 with an abutment portion 33. The abutment portion 33 covers the second bridging portion 52, and a covering space 61 is formed between the first seat 20, the abutment portion 33 of the second seat 30, the second seat 30, and the first bridging portion 42 of the first connecting rod seat 40.

[0039] The buffer assembly has a block-shaped shock absorber 62 made of an elastic material (e.g., rubber), which is disposed within the enclosed space 61. The top surface of the shock absorber 62 abuts against the first seat 20, the bottom surface of the shock absorber 62 abuts against the second seat 30, the front side of the shock absorber 62 abuts against the first bridging portion 42, and the rear side of the shock absorber 62 abuts against the first bridging portion 42. The buffer assembly may also be a spring that can elastically return to its original position.

[0040] In addition, the connecting rod damping device also has an adjusting component, such as... Figure 2 and Figure 3In the illustrated embodiment, the adjusting member has a block 63 and a bolt 64. The first bridging portion 42 of the first connecting rod seat 40 has a groove for accommodating the block 63, and the block 63 presses against the front side of the shock absorber 62. Thus, when the bolt 64 is rotated, the block 63 is driven by the bolt 64, and during the movement, it pushes or loosens the shock absorber 62, causing the shock absorber 62 to deform to different degrees, thereby adjusting the tightness of the contact between the shock absorber 62 and the first seat 20, the second seat 30, and the first connecting rod seat 40 in the enclosed space 61.

[0041] Therefore, when a cyclist sits on the saddle and begins to ride the bicycle, causing vibrations, the second seat 30 will move in conjunction with the vibrating saddle, thereby pressing against the first link seat 40 and the second link seat 50. This allows the first link seat 40 and the second link seat 50 to move relative to the first seat 20 and the second seat 30, enabling the second seat 30 to swing relative to the first seat 20 to press against the shock absorber 62. The shock absorber 62 then absorbs the vibration force and provides a buffering force that is transmitted to the saddle via the first link seat 40 and the second link seat 50, thus achieving the effect of shock absorption. It should be noted that in this invention, the shock absorber 62 is disposed within the enclosing space 61, and the outer peripheral surface of the shock absorber 62 can be provided with buffering force by the pressure of the first seat 20, the abutment part 33, the second seat 30 and the first bridging part 42, respectively, so that the shock absorber 62 can be squeezed more effectively, which can ensure that the seat cushion has a more effective shock absorption effect.

[0042] In addition, such as Figures 4 to 6 The diagram shows another optional embodiment of the present invention. In this embodiment, the linkage shock absorber can also be installed between the handlebar seat 13 and the seat tube 14. The handlebar seat 13 is used to install a handlebar 15, while the seat tube 14 is fitted onto a fork steerer tube (not shown). The linkage shock absorber also includes at least: a first seat 20, a second seat 30, a first linkage seat 40, a second linkage seat 50, and a buffer assembly. The first seat 20 is disposed on the handlebar seat 13, and has a front upper pivot end 21 and a front lower pivot end 23 on its upper and lower sides, respectively. The second seat 30 is disposed on the seat tube 14, and has a rear upper pivot end 34 and a rear lower pivot end 32 on its upper and lower sides, respectively.

[0043] In this embodiment, with Figures 1 to 3Similar to the previous embodiment shown, the buffer assembly can be a block-shaped shock absorber 62 made of an elastic material (e.g., rubber) or a spring that can elastically return to its original position; in addition, an adjustment element can also be provided to adjust the tightness of the shock absorber 62 in the enclosed space 61 abutting against the first seat 20, the second seat 30 and the first connecting rod seat 40.

[0044] The first connecting rod seat 40 also has two first connecting rod portions 41 and a first bridging portion 42 connecting the two first connecting rod portions 41. The front and rear ends of the two first connecting rod portions 41 are respectively pivotally connected between the front upper pivot end 21 and the rear upper pivot end 34. The second connecting rod seat 50 has two second connecting rod portions 51 and a second bridging portion 52 connecting the two second connecting rod portions 51. The front and rear ends of the two second connecting rod portions 51 are respectively pivotally connected between the front lower pivot end 23 and the rear lower pivot end 32. The front end of the rear lower pivot end 32 of the second seat 30 extends toward the first seat 20 with an abutment portion 33. The abutment portion 33 covers the second bridging portion 52. The covering space 61 is located between the first seat 20, the abutment portion 33, the second seat 30 and the first bridging portion 42. The shock absorber 62 is also disposed in the covering space 61.

[0045] As can be seen from the above, when a rider encounters an uneven road while riding a bicycle, the fork stem tube will cause the stem tube seat 14 to move up and down. At this time, the first link seat 40 and the second link seat 50 will press against the shock absorber 62 when they shake. The shock absorber 62 buffers and absorbs the vibration force received by the fork stem tube, so that the vibration of the handlebar seat 13 and the handlebar can be reduced to the minimum, thereby effectively reducing the discomfort of riding.

[0046] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many variations under the guidance of the present invention without departing from the inventive spirit and scope of protection of the claims. These variations are all within the protection scope of the present invention.
