In the present embodiment, the bicycle 10 includes both the front fork shock absorber 11 and the rear shock absorber 12 (disposed on the front fork 101). However, in other embodiments, the bicycle 10 may be configured with only one of the front fork shock absorber 11 or the rear shock absorber 12. The bicycle automatic adjustment damping system is exemplified below with the bicycle 10 described above.

First embodiment

2 is a block diagram of a bicycle automatic adjustment damping system in accordance with a first embodiment of the present invention. In the present embodiment, the bicycle automatic adjustment damping system 200 includes a vibration sensor 210, a signal receiving device 220, a control processing device 230, and damping. Adjustment device 240.

The vibration sensor 210 may be disposed at a position of the seat cushion 107 of the bicycle 10, the seat cushion 108, the handlebar 112, the rider vertical pole 111, the frame 100, the head pipe 113, the front fork 101, the rear fork 114, or the rear suspension 12 . The vibration sensor 210 detects vibration generated by the body of the bicycle 10, thereby outputting a corresponding vibration signal. The vibration sensor 210 is, for example, a g-sensor.

The signal receiving device 220 is coupled to the vibration sensor 210 and the control processing device 230 to receive the vibration signal of the vibration sensor 210 and transmit the vibration signal to the control processing device 230. Here, the signal receiving device 220 can receive and transmit signals through wired or wireless transmission.

The control processing device 230 is coupled to the signal receiving device 220 and the damping adjusting device 240. The control processing device 230 outputs a level control signal according to the received vibration signal, whereby the level of the damping force of the damping adjustment device 240 can be controlled. That is, the control processing device 230 can be used to control the compression damping, the rebound damping, or the gas pressure of the gas spring by outputting the level control signal to the damping adjustment device 240. In addition, the control processing device 230 can also simultaneously control the transmission gear position, the tire tire pressure, and the like. Here, the control processing device 230 may be disposed at the position L1 or the position L2 as shown in FIG. 1. However, the above positions L1 and L2 are merely illustrative, and the control processing device 230 may be disposed at any position of the bicycle 10.

The damping adjustment device 240 is coupled to the control processing device 230 to adjust the level of the damping force according to the level control signal. A damping adjustment device 240 may be disposed in each of the front fork absorber 11 and the rear suspension 12 as shown in FIG. Control processing equipment The set 230 can simultaneously control the damping force of the front fork shock absorber 11 and the rear shock absorber 12, and can also control only the damping force of one of the front fork shock absorber 11 or the rear shock absorber 12.

Here, the magnitude of the damping force represents the degree to which the compression damped valve is opened. The damping force level is smaller than the damping force, indicating that the compression damping valve is open to a greater extent. In other embodiments, the total number of levels may be set to 2 or greater than 2, such as level 1~2, level 1~3, or level 1~5.

In this embodiment, the control processing device 230 calculates the vibration parameter according to the vibration signal, thereby outputting the level control signal corresponding to the vibration parameter to the damping adjustment device 240, so that the damping adjustment device 240 adjusts the level of the damping force based on the level control signal. The higher the vibration parameter, the smaller the level of the adjusted damping force, and the lower the vibration parameter, the greater the level of the adjusted damping force.

Figure 3 is a schematic illustration of a vibration signal in accordance with a first embodiment of the present invention. In the waveform of the vibration signal shown in FIG. 3, the time period of each sampling is 0.01 second, and the number of sampling times is 8 times, and the acceleration difference Δ1 to Δ8 of 8 segments (that is, T1 to T8) can be obtained. The vibration parameters (under the code V) are calculated as follows:

Where N is the number of samples for calculating the vibration parameters. Assuming that the preset time zone is 0.08 seconds, that is, the vibration parameter is calculated once every 0.08 seconds (N=8), the vibration parameters are obtained by adding the acceleration differences obtained by each sampling. That is, V = Δ1 + Δ2 + Δ3 + Δ4 + Δ5 + Δ6 + Δ7 + Δ8. However, the preset time period of 0.08 seconds is merely an example and is not limited thereto. In other embodiments, it can also be set as a pre- Let the time zone be 1 second (ie, N=100), and the number of seconds of the preset time zone is not limited here.

After the control processing device 230 obtains the vibration parameter, the level of the damping force can be further determined according to the vibration parameter. The bottom is an example of how to determine the level of damping force.

4 is a flow chart of a bicycle automatic adjustment damping method in accordance with a first embodiment of the present invention. Referring to FIG. 2 and FIG. 4 , in step S405 , the vibration sensor 210 detects the vibration generated by the body of the bicycle, thereby outputting the vibration signal and transmitting the vibration signal to the control processing unit 230 via the signal receiving device 220 .

Next, in step S410, the control processing unit 230 calculates the vibration parameter based on the vibration signal. The calculation of the vibration parameters can be referred to the description of FIG. 3 described above. Moreover, in step S415, the control processing unit 230 determines whether the vibration parameter is greater than the vibration threshold T, thereby outputting the level control signal corresponding to the vibration parameter to the damping adjustment device 240. If the vibration parameter is not greater than the vibration threshold T, it indicates that the road surface on which the bicycle 10 is currently passing is relatively flat, so that the damping force can be increased. Therefore, the control processing unit 230 outputs a level control signal for damping the level of the damping force to the damping. Adjustment device 240. If the vibration parameter is greater than the vibration threshold value T, it indicates that the road surface through which the bicycle 10 is currently passing is relatively bumpy, so that the damping force can be reduced. Therefore, the control processing unit 230 outputs a level control signal for adjusting the level of the damping force to the damping adjustment. Device 240.

Here, if the vibration parameter is not greater than the vibration threshold value T, the damping adjustment device 240 sets the level of the damping force to D1 (first damping level) in step S420. If the vibration parameter is greater than the vibration threshold value T, in step S425, the damping adjustment device 240 sets the level of the damping force to D2 (second damping level). Where D1 is greater than D2.

The bicycle automatic adjustment damping system 500 is an application example of the bicycle automatic adjustment damping system 200. Here, members having the same functions as those of the bicycle automatic adjustment damping system 200 are given the same reference numerals, and the related description will be omitted.

The bicycle automatic adjustment damping system 500 includes a vibration sensor 210, a signal receiving device 220, a control processing device 230 damping adjustment device 240, and a stepping back speed sensor 510. The stepping speed sensor 510 is coupled to the signal receiving device 220 for detecting the pedaling speed of the bicycle 10 and outputting the pedaling signal. The stepping back speed sensor 510 can be disposed at one of the toothed disc 103 of the bicycle 10, the crank shaft 104, the crank 105, the pedal 106, and the frame 100. In addition, the stepping back speed sensor 510 can also be worn on the legs of the rider of the bicycle 10, such as at the legs (inside the thighs) or shoes. The control processing device 230 determines the initial damping level based on the tread signal.

Referring to FIG. 5 and FIG. 6, in step S605, the stepping speed of the bicycle 10 is detected by stepping back the speed sensor 510, and the stepping signal is output.

Next, in step S610, the control processing device 230 determines the initial damping level D_ini according to the tread signal. For example, two threshold values can be set to determine whether the treadback speed belongs to a high speed state, a normal state, or a low speed state. Assume that the threshold is th1 and th2, and th2>th1. When the pedaling rotational speed is greater than th2, it is determined to be a high speed state, and the initial damping level D_ini is set to D _firm . When the pedaling rotational speed is less than or equal to th2 and greater than or equal to th1, it is determined to be a normal state, and the initial damping level D_ini is set to D _medium . When the pedaling rotational speed is less than th1, it is determined to be a low speed state, and the initial damping level D_ini is set to D _soft . And D _firm >D _medium >D _soft .

After determining the initial damping level D_ini, in step S615, the vibration sensor 210 detects the vibration generated by the body of the bicycle, thereby outputting the vibration signal and transmitting the vibration signal to the control processing unit 230 via the signal receiving device 220. Next, in step S620, the control processing unit 230 calculates the vibration parameter based on the vibration signal. The calculation of the vibration parameters can be referred to the description of FIG. 3 described above. Moreover, in step S625, the control processing unit 230 determines whether the vibration parameter is greater than the vibration threshold T, thereby outputting the level control signal corresponding to the vibration parameter to the damping adjustment device 240. If the vibration parameter is not greater than the vibration threshold value T, the damping adjustment device 240 sets the level of the damping force to D1 (first damping level) in step S630. If the vibration parameter is greater than the vibration threshold value T, in step S635, the damping adjustment device 240 sets the level of the damping force to D2 (second damping level). Where D1 is greater than D2.

Third embodiment

Figure 7 is a block diagram of a bicycle automatic adjustment damping system in accordance with a third embodiment of the present invention. The bicycle automatic adjustment damping system 700 is an application example of the bicycle automatic adjustment damping system 200. Here, members having the same functions as those of the bicycle automatic adjustment damping system 200 are given the same reference numerals, and the related description will be omitted.

The bicycle automatic adjustment damping system 700 includes a vibration sensor 210 and a signal The receiving device 220 and the control processing device 230 dampen the adjusting device 240 and the posture sensor 710. The posture sensor 710 is configured to detect that the rider uses the posture of riding the bicycle 10 as a standing stepping posture or riding a pedaling posture, and outputs a posture signal. The gesture sensor 710 is coupled to the signal receiving device 220 to transmit the gesture signal to the control processing device 230 through the signal receiving device 220, so that the control processing device 230 determines the vibration threshold value T1 or T2 according to the posture signal.

The posture sensor 710 is disposed on the bicycle 10, the seat cushion 107, the seat cushion 108, the grip 110, the handlebar 112, the rider vertical pole 111, the pedal 106, the frame 100, the front fork 101, the rear shock absorber 12, and the flower hub 109 and the crank shaft 104 and the like are used to obtain sensing data for judging the rider's pedaling posture.

The pressure sensor is used as the posture sensor 710 as an example for explanation. A pressure sensor can be provided in the seat cushion 107 or the seat cushion 108 as the posture sensor 710. When the posture sensor 710 senses the force, it indicates that the pedaling posture is a riding stepping posture; when the posture sensor 710 does not sense the force, the pedaling posture is a standing pedaling posture. Alternatively, a left and right two pedals 106 or two left and right grips 110, a handlebar 112 or a rider vertical bar 111 (or any two points of the bicycle) are respectively provided with a pressure sensor as a sense of posture. Detector 710. However, not limited thereto, the posture sensor 710 can also be an optical sensor or a radar, or other sensors that can detect the rider's center of gravity and posture change.

In actual riding, the rider will prepare in advance according to the road condition and change the riding mode simultaneously. For example, in the event of an obstacle, the rider will stop pedaling and pass at a low speed (to reduce the jitter of the car body); when riding the slope, the rider generally The pedaling posture will be switched and the body will be moved forward and changed to the light speed to change the speed; in the case of a curved road section, the rider generally lowers the riding center of gravity and lowers the pedaling speed. Accordingly, two sets of parameters can be respectively set corresponding to the standing stepping posture and the riding stepping posture, each group parameter including a vibration threshold value and two damping levels. In the set of parameters corresponding to the standing stepping posture, the vibration threshold is T1, and the damping levels are D_11 and D_12, respectively. In the set of parameters corresponding to the riding and stepping posture, the vibration threshold is T2, and the damping levels are D_13 and D_14, respectively. The above T1 and T2 may be the same or different.

Figure 8 is a flow chart of a bicycle automatic adjustment damping method in accordance with a third embodiment of the present invention. Referring to FIG. 7 and FIG. 8 , in step S805 , the vibration sensor 210 detects the vibration generated by the body of the bicycle 10 , thereby outputting the vibration signal and transmitting the vibration signal to the control processing unit 230 via the signal receiving device 220 . Next, in step S810, the control processing unit 230 calculates the vibration parameter based on the vibration signal.

Then, in step S815, the posture sensor 710 detects that the rider adopts the posture of riding the bicycle 10 as a standing stepping posture or riding a pedaling posture, and outputs a corresponding posture signal, so that the control processing device 230 is controlled. The vibration threshold is set to T1 or T2 according to the posture signal. Step S815 may also be performed before step S805 or concurrently with S805, and the execution sequence of step S815 is not limited herein.

When it is determined in step S815 that the standing stepping posture is present, in step S820, the control processing means 230 determines whether the vibration parameter is greater than the vibration threshold value T1. When the vibration parameter is not greater than the vibration threshold T1, in step S825, the damping adjustment device 240 is caused to set the level of the damping force to D_11 (first damping level). When vibrating When the parameter is greater than the vibration threshold value T1, in step S830, the damping adjustment device 240 is caused to set the level of the damping force to D_12 (second damping level). Among them, D_11 is greater than D_12.

When it is determined in step S815 that the riding posture is stepped on, in step S835, the control processing means 230 determines whether the vibration parameter is greater than the vibration threshold value T2. When the vibration parameter is not greater than the vibration threshold T2, in step S840, the damping adjustment device 240 is caused to set the level of the damping force to D_13 (third damping level). When the vibration parameter is greater than the vibration threshold value T2, in step S845, the damping adjustment device 240 is caused to set the level of the damping force to D_14 (fourth damping level). Among them, D_13 is greater than D_14. Moreover, since the center of gravity of the station is easier to swing when riding, a higher damping level is required for the mount, so the preferred embodiment is to simultaneously set D_13<D_11, D_14<D_12.
