[0087] The following further describes the adjustment method of the damping of the bicycle shock absorber 3. Figures 8 to 10 As shown, the damping unit 11 indirectly drives the valve stem 114 to move along the axial direction of the front fork under the operation of the motor 113, so that the end of the valve stem 114 changes its position to a closed flow channel 115, a close flow channel 115, and a distant flow channel 115, so that the fluid cannot flow, has limited flow (obstructed by the end of the valve stem 114), and flows smoothly (not obstructed by the end of the valve stem 114), respectively forming a front fork locking state (corresponding to the hard shock absorption mode 112), a front fork relaxation state (corresponding to the balanced shock absorption mode 113), and a front fork relaxation state (corresponding to the balanced shock absorption mode 114). The amount of axial displacement of the valve stem 114 can be determined by the rotation of the blade 116 driven by the motor 113, and the number of rotations of the blade 116 can be sensed by the photo interrupter 117, so as to calculate the axial displacement of the valve stem 114 indirectly driven by the motor 113, so as to achieve the aforementioned closed flow channel 115 at the end of the valve stem 114, the close flow channel 115, and the far flow channel 115, thereby forming the compression damping effect of the bicycle shock absorber 3.

[0088] Therefore, when the shock absorbing mode unit 12 executes the automatic shock absorbing mode 120 (eg Fig.12As shown), the left longitudinal axis in the diagram is acceleration (m / s2), and the lower transverse axis is the time elapsed during driving (sec). The diagram also shows five transverse blocks, the middle block shows that the bicycle shock absorber 3 is adjusted to the damping effect of the hard shock absorption mode 112 in the acceleration range of 0.1 m / s2 to -0.18 m / s2. The sandwich block shows that when the acceleration is -1.8 m / s2 to -0.4 m / s2 and 0.18 m / s2 to 0.38 m / s2, the bicycle shock absorber 3 is adjusted to the damping effect of the balanced shock absorption mode 111. The outermost block shows that the acceleration values ​​of -0.4 m / s2 to -0.62 m / s2 and 0.38 m / s2 to -0.6 m / s2 are adjusted to the damping effect of the soft shock absorption mode 110.

[0089] Please refer to Fig.15 As shown, the shock-absorbing module 1 and the controller 4 must be paired before use, and after pairing, the subsequent steps are performed, including:

[0090] Step 1: The shock absorber module 1 and the controller 4 are initially paired. If the pairing is successful (YES), proceed to step 2. If the pairing is unsuccessful (NO), proceed to step 3.

[0091] Step 2: The shock-absorbing module 1 forms a wireless signal connection with the controller 4 and proceeds to step 4.

[0092] Step 3: Re-pair the shock absorber module 1 and the controller 4 until the pairing is successful and then proceed to step 2.

[0093] Step 4: After the shock absorber module 1 and the controller 4 form a wireless signal connection, the connection status of the shock absorber module 1 and the controller 4 will still be confirmed at any time. If it is confirmed to be in the online state (YES), go to step 5. If it is confirmed to be disconnected (NO), return to step 3.

[0094] Step 5: Confirm whether the automatic button 50 is pressed. If the automatic button 50 is pressed (YES), proceed to step 6. If the automatic button 50 is not pressed (NO), proceed to step 7.

[0095] Step 6: The shock absorption mode unit 12 of the shock absorption module 1 executes the automatic shock absorption mode 120, the sensing unit 13 automatically senses the vibration of the bicycle and transmits the sensing signal to the control unit 10, and the control unit 10 transmits the control signal to the damping unit 11, and the damping unit 11 automatically adjusts the damping of the bicycle shock absorber 3.

[0096] Step 7: The shock absorption mode unit 12 of the shock absorption module 1 executes the manual shock absorption mode 121. The user manually turns the paddle 51 according to the driving conditions, so that the manual switching unit 42 transmits a switching signal to the damping unit 11, and the damping unit 11 adjusts the damping of the bicycle shock absorber 3.

[0097] Step 8: Confirm whether the automatic button 50 is pressed again. If the automatic button 50 is not pressed again (NO), the shock absorption mode unit 12 continues to execute the automatic shock absorption mode 120 in step 6. If the automatic button 50 is pressed again (YES), the shock absorption mode unit 12 leaves the automatic shock absorption mode 120 and returns to step 7 to execute the manual shock absorption mode 121.

[0098] As described above, it is known that in actual operation of the present invention, after the suspension module 1 is successfully paired with the controller 4, by pressing the automatic button 50, the pressing unit 41 transmits a first pressing signal and transmits it to the first wireless transmitting unit 14 via the second wireless transmitting unit 40, and then the first pressing signal is transmitted to the suspension mode unit 12 via the first wireless transmitting unit 14, so that the suspension mode unit 12 executes the automatic suspension mode 120, and the vibration during the bicycle driving is sensed by the sensing unit 13 (the detection and judgment direction is defined as the front fork extension and retraction operation direction, and the acceleration of the aforementioned vibration is m / s2) and the sensing signal is sent to the control unit 10, and the control unit 10 transmits a control signal to the damping unit 11, and the damping response of the automatic suspension 3 is changed in real time through the damping unit 11.

[0099] In addition, the user can press the automatic button 50 again to make the pressing unit 41 transmit a second pressing signal and transmit it to the first wireless transmitting unit 14 via the second wireless transmitting unit 40, and then transmit the second pressing signal to the shock absorbing mode unit 12 via the first wireless transmitting unit 14, so that the shock absorbing mode unit 12 switches from the automatic shock absorbing mode 120 to the manual shock absorbing mode 121. At this time, the user can make the manual switching unit 42 transmit different switching signals to the damping unit 11 each time the paddle 51 is turned, so that the damping unit 11 switches to a different shock absorbing mode. For example, if Figure 3 As shown, when the user first moves the paddle 51 in the first direction F1, the manual switching unit 42 receives the first switching signal, and the damping unit 11 executes the soft shock absorption mode 110. If the user moves the paddle 51 in the first direction F1 for the second time, the manual switching unit 42 receives the second switching signal, and the damping unit 11 switches to the balanced shock absorption mode 111. If the user moves the paddle 51 in the first direction F1 for the third time, the manual switching unit 42 receives the third switching signal, and the damping unit 11 switches to the hard shock absorption mode 112. Accordingly, the user can manually adjust the damping unit 11 to execute different shock absorption modes, and quickly adjust the damping effect of the automatic shock absorber 3 in a simple manner, especially when applied to known road conditions, such as paved roads, sandy mixed roads, or bumpy and rugged forest roads, to provide appropriate autonomous control. In addition, the user can also make the seat post control unit 71 drive the seat post 8 to rise and fall by moving the paddle 51 in the second direction F2.

[0100] It is worth mentioning that the shock-absorbing module 1 can be further wirelessly connected to the anti-theft alarm module 92 (such as Fig.16 For example, when a thief steals a bicycle, the sensing unit 13 senses the abnormal vibration of the bicycle and sends an anti-theft signal to the control unit 10, causing the control unit 10 to send a warning signal to the alarm unit (not shown) to make a sound, alerting people around and causing the thief to panic and flee, thus preventing the bicycle from being stolen and achieving the effect of warning and anti-theft.

[0101] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
