[0029] Please refer to the following: Figure 1 The shock-absorbing bicycle provided by this utility model will now be described. The shock-absorbing bicycle includes a stem 1, a sliding rod 2, and a lower seat 3; the bottom of the stem 1 is provided with a first mounting hole 11 extending downward; the stem 1 is used to connect to the rotating handlebars; one end of the sliding rod 2 extends into the first mounting hole 11 and is fixed to the stem 1, and the other end extends downward in a vertical direction; a first gap 12 is left between the upper end of the sliding rod 2 and the bottom of the first mounting hole 11; a first pressure plate 21 and a second pressure plate 22 are provided on the sliding rod 2 at intervals; the top of the lower seat 3 is provided with a second mounting hole 311 suitable for the lower end of the sliding rod 2 to extend into, and the lower seat 3 is fixed to the lower end of the sliding rod 2; a second gap 312 is left between the lower end of the sliding rod 2 and the bottom of the second mounting hole 311; the two ends of the bottom of the lower seat 3 are used to connect the left bracket 9 and the right bracket 10 on both sides of the front wheel, respectively; wherein, a first shock-absorbing component 4 is provided between the first pressure plate 21 and the lower end of the stem 1, and a second shock-absorbing component 5 is provided between the second pressure plate 22 and the lower seat 3.
[0030] Specifically, the first pressure plate 21 and the second pressure plate 22 are annular plates, with the first pressure plate 21 located near the upper end of the sliding rod 2 and the second pressure plate 22 located near the lower end of the sliding rod 2. By arranging the first pressure plate 21 and the second pressure plate 22 in an annular configuration, the contact area with the first damping component 4 and the second damping component 5 can be increased, stress concentration can be reduced, and the service life of the sliding rod 2 can be guaranteed. Preferably, the first pressure plate 21 and the second pressure plate 22 are arranged symmetrically vertically.
[0031] It should be understood that the left bracket 9 and the right bracket 10 are used to connect to the front axle of the bicycle respectively, in order to drive the front wheel to rotate. The connection structure and working principle of this part are existing technologies and will not be described in detail here.
[0032] By fixing the upper end of the sliding rod 2 to the riser 1 and the lower end of the sliding rod 2 to the lower seat 3, it can be ensured that the torque is transmitted to the left bracket 9 and the right bracket 10 when the handlebar is turned, thus avoiding relative rotation between the sliding rod 2, the riser 1, and the lower seat 3. Optionally, the upper end of the sliding rod 2 and the first mounting hole 11, and the lower end of the sliding rod 2 and the second mounting hole 311 can be connected by threads.
[0033] Compared with the prior art, the shock-absorbing bicycle provided by this utility model has a first gap 12 and a second gap 312 respectively provided at the connection of the upper and lower ends of the sliding rod 2. This allows the sliding rod 2 to have a buffer and shock-absorbing space when the lower seat 3 vibrates with the left support 9 and the right support 10, reducing the transmission of vibration from bottom to top. Furthermore, a first shock-absorbing component 4 is provided between the first pressure plate 21 and the stem 1, and a second shock-absorbing component 5 is provided between the second pressure plate 22 and the lower seat 3, which can absorb some vibration and reduce the transmission of vibration to the handlebars. The shock-absorbing bicycle provided by this application can reduce the transmission of wheel vibration to the handlebars by simultaneously damping the upper and lower parts, resulting in a significant shock-absorbing effect and a long service life.
[0034] Please see Figure 1 In some possible embodiments, the lower end of the riser 1 is provided with a ring-shaped docking plate 13, and the first pressure plate 21 is in a ring shape corresponding to the docking plate 13, and the docking plate 13 and the first pressure plate 21 press the first shock-absorbing component 4 together.
[0035] By setting the connecting plate 13, the first shock-absorbing component 4 is pressed between the connecting plate 13 and the first pressure plate 21, thereby reducing the damage to the riser 1 caused by stress concentration.
[0036] Please see Figure 1 In some embodiments, the first damping component 4 includes a first damping ring 41 placed between the first pressure plate 21 and the lower end of the riser 1. The first damping ring 41 is annularly sleeved on the outer peripheral wall of the upper end of the sliding rod 2.
[0037] Specifically, the inner wall of the first damping ring 41 abuts against the outer peripheral wall of the sliding rod 2. The first damping ring 41 can absorb part of the vibration transmitted upward by the sliding rod 2, and the first gap 12 can reserve a damping gap for vibrations that are not completely absorbed, thereby improving the damping capability of this device.
[0038] Optionally, the first damping ring 41 is made of rubber damping material, which can absorb the vibration transmitted upward by the sliding rod 2 to achieve the effect of damping.
[0039] Specifically, the first damping ring 41 is a conical structure with a radial dimension that gradually increases from top to bottom. It can gradually absorb the vibration on the sliding rod 2 through the gradual diameter of the first damping ring 41, and the vibration absorption capacity gradually increases with the increase of the radial dimension.
[0040] Please see Figure 1 For example, the first shock-absorbing assembly 4 also includes two sets of first pads 42 respectively disposed at the upper and lower ends of the first shock-absorbing ring 41, and one of the first pads 42 abuts against the bottom of the docking plate 13, and the other first pad 42 abuts against the top of the first pressure plate 21.
[0041] By setting the first shim 42 and the second shim 54 to abut against the upper and lower ends of the first damping ring 41 respectively, the wear of the upper and lower ends of the first damping ring 41 is reduced, and the service life of the first damping assembly 4 is extended.
[0042] Please see Figure 1 In some possible embodiments, the second damping assembly 5 includes a mounting housing 51, a second damping ring 52, and a third damping ring 53; the mounting housing 51 is fixed to the top of the lower seat 3; the mounting housing 51 has a downward-opening mounting space; wherein, the sliding rod 2 passes downward through the top of the mounting housing 51 and the mounting space, and enters the second mounting hole 311; the second damping ring 52 is arranged around the sliding rod 2 and abuts against the top of the mounting housing 51 and the second pressure plate 22; the third damping ring 53 is disposed in the mounting space and is arranged around the sliding rod 2; the third damping ring 53 abuts against the top of the mounting space and the top of the lower seat 3.
[0043] By setting the second damping ring 52 and the third damping ring 53, most of the vibration transmitted from the left support 9 and the right support 10 can be absorbed. In addition, a second gap 312 is provided at the lower end of the sliding rod 2 to provide a buffer gap for unabsorbed vibration, thereby reducing vibration.
[0044] Specifically, the second damping ring 52 is a conical structure with a radial dimension that gradually increases from top to bottom, and the third damping ring 53 is a conical structure with a radial dimension that gradually decreases from top to bottom.
[0045] Please see Figure 1 In some embodiments, a second gasket 54 is provided between the top of the second damping ring 52 and the second pressure plate 22; a third gasket 55 is provided between the third damping ring 53 and the top of the lower seat 3.
[0046] By providing a second shim 54 and a third shim 55 to abut against the ends of the second damping ring 52 and the third damping ring 53 respectively, the contact area between the ends of the second damping ring 52 and the third damping ring 53 is increased, the wear at the ends of the second damping ring 52 and the third damping ring 53 is reduced, and the service life is extended.
[0047] Specifically, the second gasket 54 and the third gasket 55 can be made of steel plates, and their thickness can be set according to actual needs.
[0048] Please see Figure 1 For example, a connecting sleeve 56 is provided on the outer peripheral wall of the lower end of the sliding rod 2.

The lower end of the connecting sleeve 56 passes downward between the third damping ring 53 and the sliding rod 2 and abuts against the third gasket 55. The middle part of the connecting sleeve 56 is fixed to the mounting housing 51.
[0049] It should be understood that when the second damping ring 52 and the third damping ring 53 absorb vibration, a small amount of vibration will still cause the second damping ring 52 and the third damping ring 53 to slide up and down. In this application, a connecting sleeve 56 is provided so that the connecting sleeve 56 is arranged around the outside of the sliding rod 2, thereby separating the inner sliding rod 2 from the outer second damping ring 52 and the third damping ring 53, and avoiding friction damage caused by mutual friction between the second damping ring 52 and the third damping ring 53 and the sliding rod 2.
[0050] Please see Figure 1 In some possible embodiments, the lower seat 3 has an upwardly protruding mounting portion 31 at its top, and a second mounting hole 311 is provided in the mounting portion 31; a plurality of first threaded parts 6 are provided at intervals on the outer peripheral wall of the mounting portion 31, and the first threaded parts 6 pass through the mounting portion 31 along the radial direction of the sliding rod 2 and are fixed in the sliding rod 2.

Furthermore, the aforementioned second mounting hole 311 is provided on the mounting part 31, and a second gap 312 is left between the end of the sliding rod 2 and the bottom of the second mounting hole 311, so as to leave a buffer space for vibration, thereby achieving the purpose of vibration reduction and noise reduction.

[0053] By setting an annular pad 8, it is convenient to support the third pad 55 on the top of the annular pad 8, so that the third pad 55 abuts against the bottom of the third damping ring 53, thereby supporting the bottom of the third damping ring 53; by setting the above-mentioned clearance, it is convenient to accommodate the end of the first threaded part 6, and avoid interference between the annular pad 8 and the first threaded part 6.
[0054] Optionally, the annular pad 8 can be made of rubber or a hollow steel plate shell. The choice can be made according to actual needs.
[0055] Please see Figure 1 In some possible embodiments, multiple sets of second threaded parts 7 are spaced apart on the outer peripheral wall of the riser 1. The second threaded parts 7 pass through the riser 1 radially along the sliding rod 2 and are fixed inside the sliding rod 2.
[0056] By setting the second threaded part 7 to fix the stem 1 and the sliding rod 2, the stem 1 can drive the sliding rod 2, the left bracket 9 and the right bracket 10 to rotate when the handlebars are turned, thereby realizing the steering of the bicycle.
