[0022] As Figure 1 and Figure 2 shown, in this creation, the handlebar 11 of the bicycle is connected to a front fork upright tube 12 by a riser tube. The riser tube is provided with a riser seat 2 and a handlebar seat 3. The front fork upright tube 12 is connected to the front wheel of the bicycle (not shown) below. The riser seat 2 is integrally provided with a pivoting portion 21 and a sleeve portion 22. The sleeve portion 22 is sleeved on the top end of the front fork upright tube 12. The handlebar seat 3 is integrally provided with a pair of clamping ears 31 and a socket portion 32. The socket portion 32 is socketed on the handlebar 11 of the bicycle. A pair of clamping ears 31 are pivotally connected to the pivoting portion 21 through a pivoting assembly 4 to form the connection between the handlebar 11 and the front fork upright tube 12. Further, a cable positioning structure 13 is provided between the riser seat 2 and the front fork upright tube 12. The cable positioning structure 13 is assembled at the bottom of the riser seat 2, and the cable positioning structure 13 has a wire passing opening 131 that communicates inside and outside relative to the lower side of the handlebar seat 3. The user can conveniently and easily insert the cable into the wire passing opening 131 from the bottom side of the handlebar seat 3, so that most of the cables are not exposed outside the frame. This can not only avoid problems such as messy wiring and friction or damage of the cables, but also optimize the overall appearance of the entire bicycle.

[0023] The shock absorption device of this case at least includes: at least one extension member 5, at least one shock absorption component 6, and an adjustment member 7; wherein:

[0024] The extension member 5 is integrally extended from the pivoting portion 21 of the riser seat towards the handlebar 11. A receiving space 51 is formed between the extension member 5 and the main body 33 of the handlebar seat 3. The extension member 5 has a threaded hole 52. A shock absorption component 6 is installed in the receiving space 51. Among them, the shock absorption component 6 can be a spring, and the main body 33 of the handlebar seat has a slot 331, and the slot 331 has a shape corresponding to the extension member 5.

[0025] Please also refer to as Figure 3As shown, the adjusting member 7 has a screwing portion 71 and a rod body 72 integrally protruding from the screwing portion 71. The outer diameter of the rod body 71 is smaller than that of the screwing portion 71, so that the screwing portion 71 abuts against the rod body 72 with a relatively large shoulder 73.

[0026] During overall assembly, the riser base 2 and the handlebar base 3 are assembled with each other in an up-and-down docking manner. The extension member 5 is placed into the slot 331. There is a gap 332 between the slot 331 and the outer peripheral edge of the extension member 5. The shock-absorbing assembly 6 is positioned in the accommodation space 51 by using the adjusting member 7. Among them, the screwing portion 71 is screwed into the screw hole 52, and the rod body 72 extends into the shock-absorbing assembly 6, so that the shock-absorbing assembly 6 is positioned between the main body 33 and the screwing portion 71. The upper end of the shock-absorbing assembly 6 abuts against the lower part of the main body 33, and the lower end of the shock-absorbing assembly 6 abuts against the upper part of the shoulder 73. The overall assembled parts are greatly simplified and the assembly process is simple.

[0027] When the user rides a bicycle on an uneven road and the bicycle shakes, the front fork upright tube 12 sleeved by the sleeve portion 22 of the riser base 2 will move up and down. At this time, when the handlebar base 3 shakes accordingly, the main body 33 of the handlebar base will press against the shock-absorbing assembly 6. The shock-absorbing assembly 6 absorbs the force of the up-and-down vibration of the front fork upright tube 12, reducing the degree of shaking of the handlebar base 3, so that the handlebar 11 sleeved on the handlebar base 3 will not vibrate or only vibrate slightly, effectively reducing the discomfort caused by the body vibration. And the user can also use a hand tool to adjust the relative position of the adjusting member 7 in the screw hole 52, thereby adjusting the degree to which the shock-absorbing assembly 6 is squeezed by the shoulder 73, so as to adjust the strain degree of the shock-absorbing assembly 6 to achieve different shock-absorbing effects.

[0028] Furthermore, there is at least one buffer gasket 81 between the riser base 2 and the main body 33. In the illustrated embodiment, the buffer gasket 81 is fixedly positioned on the riser base 2 and relative to the extension member 5. Among them, the side wall surface of the riser base 2 relative to the main body 33 has a recessed portion 23, and the buffer gasket 81 has a convex portion 82 that can extend into and be positioned in the recessed portion 23. By inserting the convex portion 82 into the recessed portion 23, the buffer gasket 81 is fixedly positioned on the riser base 2 and can isolate the riser base 2 and the main body 33. Using the buffer gasket 81 can reduce the impact noise and collision feeling when the handlebar base 3 rebounds, and can greatly improve the riding experience. Of course, the buffer gasket can also be fixedly positioned on the main body.

[0029] In addition, the pivot assembly 4 has a first and a second pressing member 41, 42 and two gaskets 43 that can be fixedly grouped with each other. The outer ends of the first and second pressing members 41, 42 cooperate with the clamping ears 31 to form a cover plate 44. By docking the first and second pressing members 41, 42 with each other, the connection between the handlebar 11 and the front fork upright tube 12 is constituted. Among them, the two gaskets 43 are preferably made of metal. The two gaskets 43 made of metal can reduce the loss caused by the mutual locking of the pivot assembly.

[0030] Please also refer to the second embodiment shown in Figure 4 In the second embodiment, the extension member 5 has a neck portion 53 extending and connected to the pivot portion 21, and an enlarged portion 54 connected to the other end of the neck portion 53. The area of the enlarged portion 54 is larger than the area of the neck portion 53, and the screw hole 52 is located in the enlarged portion 54. When the riser base 2 and the handlebar base 3 are assembled with each other in an up-and-down docking manner, by virtue of the arrangement of the neck portion 53 and the enlarged portion 54, it is not only convenient to place the extension member 5 into the slot 331, but also enables the two to be quickly aligned without displacement, further adding to the convenience of assembly.

[0031] In addition, as shown in Figure 5 As shown, the main body 33 of the handlebar base 3 forms at least one positioning portion 333 relative to the accommodating space 51, which can be used to position the shock absorption assembly 6. In the embodiment shown in the figure, the positioning portion 333 can be set as a structure protruding from the main body, which can be inserted into the shock absorption assembly 6 for positioning. Of course, the positioning portion can also be set as a structure recessed from the main body, which can accommodate the shock absorption assembly for positioning.
