In order to explain the technical features of the present invention in detail, the following preferred embodiments are described below with reference to the accompanying drawings, wherein: FIG. 1 to FIG. 3, the first preferred embodiment of the present invention provides The bicycle chain 10 system can be conveniently adjusted, and is mainly composed of a micro control unit 11, a memory 21, a driving unit 31 and a derailleur 41. The micro control unit 11 has processing operations. ability.

The memory 21 is electrically connected to the micro control unit 11. In actual implementation, the memory may be built in the micro control unit 11 or may be an independent memory. The memory 21 may be a non-volatile memory or an erasable memory.

The driving unit 31 is electrically connected to the micro control unit 11.

The derailleur 41 is physically connected to the driving unit 31, and is driven by the driving unit 31 to be displaced relative to a plurality of teeth G1-G11 of a bicycle (not shown) for use in the bicycle. The chain (not shown) performs a decoupling operation to achieve the movement of moving the chain from one tooth G5 (for example, the fifth tooth piece) to the other tooth piece G6 (for example, the sixth tooth piece), thereby achieving shifting shifting. Effect.

The memory 21 stores at least three location tables. In the present embodiment, ten location tables T1 to T10 are exemplified. The plurality of position tables T1 to T10 have complex position information of the derailleur 41 with respect to each of the teeth G1-G11, and a plurality of position information of the position table T1~T10 is compared with the adjacent one. The position information of the position table T1~T10 is at least partially different. In this embodiment, the difference position table T1~T10 corresponds to the same tooth (for example, the sixth tooth). The position information of the slice G6) is sorted before and after the position, and the position information of the two adjacent position tables T1 to T10 corresponding to the same tooth (for example, the sixth tooth G6) is different by a value, and if the value is two phases The adjacent position tables T1 to T10 correspond to the same position information of the same tooth piece (for example, the sixth tooth piece G6), that is, zero. The position information may be an angle value, a distance value, or a length value. In the first embodiment, the angle value is used as an example, and each position information of each of the position tables T1 TT10 is aligned with each of the teeth. The center position of the sheets G1-G11.

For the convenience of the representation, in the first embodiment, only the position table T3~T7 is shown as follows, and the other position tables are analogized by the numerical difference between the two position tables:

Location table T4

Moreover, the micro control unit 11 selects a position table T1~T10, and drives the derailleur 41 to the corresponding position by the driving unit 31 according to the position information of the position table T1~T10. The means for selecting the position table T1 to T10 may be selected by the micro control unit 11 according to an externally input electronic signal; or an input device 95 may be electrically connected to the micro control unit 11 for The micro control unit 11 selects a position table T1~T10 according to the control of the input device 95, and the input device 95 can be a button, a knob or a user operation interface.

The main technical features of the first embodiment have been described above, and the mode of operation of the first embodiment will be described next.

Before the adjustment is to be performed, the micro control unit 11 is first selected to select the position table T1~T10 in the middle position of the complex position table T1~T10, for example, the fifth position table T5, and the micro control unit 11 is controlled. The derailleur 41 is aligned with the sixth tooth piece G6.

Next, as shown in FIG. 2, the user directly observes whether the derailleur 41 is aligned with the sixth tooth piece G6, and if not aligned, causes the micro control unit 11 to select another position table T1. ~T10, since the complex position table T1~T10 is sequentially arranged by a value (in this case, the distance value is taken as an example), therefore, the sixth position table T6 or the position table T7~T10 of the later stage is selected. The micro control unit 11 can be controlled to continuously shift the derailleur 41 toward a position with a larger distance value, and the fourth position table T4 or the position table T1~T3 of the more previous stage can be selected to make the micro control The unit 11 controls the derailleur 41 to continue to be displaced toward a position where the distance value is smaller. In the second figure, the derailleur 41 is not aligned with the sixth tooth piece G6, but is located behind the sixth tooth piece G6. Therefore, the micro control unit 11 can be selected to be the sixth one. The position table T6, and again controls the position of the derailleur 41 to move to the position information of the sixth tooth piece G6 in the position table T6. Thus, as shown in FIG. 3, the derailleur 41 is Moving to the actual position of the sixth tooth piece G6, the adjustment operation is completed. Once the selected position table T1~T10 can make the derailer align with a certain piece of teeth, the position information in the position table T1~T10 can correspond to each piece of the piece.

When the actual riding is performed, the micro control unit 11 performs the shifting operation according to the selected position table T1~T10 when receiving the shifting instruction or self-determining that the shifting is to be performed, and according to the position table T1 ~T10 corresponds to the position information of each of the teeth G1-G11 to drive the derailleur 41 to move to the corresponding position.

As can be seen from the above, the user can adjust the position of the derailleur 41 by the micro control unit 11, and further, since the plurality of position information in each of the position tables T1 to T10 directly corresponds to each of the teeth G1-G11, therefore, when the position of the derailleur 41 is adjusted, the micro control unit 11 directly drives the selected position table T1~T10, so that the derailleur 41 is integrally adjusted. The position does not require the need to re-use the logic operation after each adjustment as in the prior art described above, which simplifies the complicated process that the prior art requires additional processing, has the effect of fast and saving computational energy, and is calibrated. Extremely convenient and accurate.

Referring to FIG. 4 to FIG. 5, a bicycle alignment system 10' that can be easily adjusted according to the second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that Each of the position information of each of the position tables T1'~T10' is not only aligned with the center position of each of the teeth G1'-G11', but is aligned with each of the teeth G1'-G11'. In addition to the center position, the upper chain position of the upper chain of each of the teeth G1'-G11' and the lower chain position of the lower chain of each of the teeth G1'-G11' are included, that is, each position information includes The center position, the upper chain position and the lower chain position, the upper chain position of each position information is located before the center position and is different from the center position by a predetermined value, and the center position is located before the lower chain position and the lower chain position The difference is a predetermined value. These two predetermined values are the same in actual implementation. In Fig. 5, the center position is indicated by the center line, and the upper chain position and the lower chain position are indicated by broken lines for easy understanding.

For the convenience of the representation, in the second embodiment, only the position table T3'~T7' is shown as follows, and the other position tables are analogized by the numerical difference between the two position tables:

In the second embodiment, the position control table T1'~T10' is selected by the micro control unit 11', and then the derailleur 41' is adjusted according to the position table T1'~T10'. position. The additional winding position and the lower chain position of the second embodiment mainly make the shifting smoother, because the derailer 41' is usually used when the shifting action is performed on the actual mechanism. Not only is the chain (not shown) to be aligned to the center of a certain tooth (for example, the sixth tooth G6'), but the chain is required to be pushed forward a little, that is, to the upper position. In order to allow the chain to be quickly and surely engaged with the sixth tooth piece G6'; and in the downshift of the shifting action, the derailer 41' is not only to align the chain to a certain one. The center position of the tooth piece (for example, the sixth tooth piece G6'), but the chain is required to be turned back a little, that is, to the lower chain position, so that the chain can be quickly and surely engaged with the sixth tooth piece G6. '.

As can be seen from the above, the second embodiment makes the shifting shift process smoother and more stable than the first embodiment.

The remaining technical features of the second embodiment and the achievable functions are the same as those of the first embodiment, and will not be described again.
