Detailed Description
The structure and function of the present invention will be described in detail with reference to the following embodiments and accompanying drawings. Wherein:
referring to fig. 1 to 3, a bicycle derailleur system 10 with convenient adjustment according to a first preferred embodiment of the present invention is mainly composed of a micro control unit 11, a memory 21, a driving unit 31 and a derailleur 41, wherein:
and a micro control unit 11 having the capability of processing operation.
The memory 21 is electrically connected to the micro control unit 11. In actual implementation, the memory may be a memory built in the micro control unit 11 or may be an independent memory. The memory 21 may be a non-volatile memory or a 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 performing a derailleur operation on a chain (not shown) of the bicycle, so as to move the chain from one tooth G5 (e.g., the 5 th tooth) to another tooth G6 (e.g., the 6 th tooth), thereby achieving a gear shifting effect.
The memory 21 stores at least three location tables, which are exemplified by ten location tables T1-T10 in the present embodiment. The position tables T1 to T10 have position information of the derailleur 41 with respect to the tooth plates G1 to G11, and the position information of one of the position tables T1 to T10 is at least partially different from the position information of the adjacent position tables T1 to T10, in this embodiment, taking the complete difference as an example, the position tables T1 to T10 are sorted according to the front and rear positions of the position information corresponding to the same tooth plate (e.g. the 6 th tooth plate G6), and the position information of the position tables T1 to T10 adjacent to each other by a distance value, which is zero if the position information of the two adjacent position tables T1 to T10 corresponding to the same tooth plate (e.g. the 6 th tooth plate g. G6) is the same as 3970. The position information may be an angle value, a distance value or a length value, and in the first embodiment, the angle value is taken as an example, and each position table T1-T10 has each position information aligned with the center position of each tooth piece G1-G11.
For convenience of illustration, in the first embodiment, only the position tables T3 to T7 are shown as follows, and the other position tables are analogized according to the numerical difference between two position tables:
position table T3
Position table T4
Position table T5
Position table T6
Position table T7
The micro-control unit 11 selects one of the position tables T1-T10, and drives the derailleur 41 to move to the corresponding position through the driving unit 31 according to the position information of the position tables T1-T10. The means for selecting the position tables T1 to T10 may be selected by the micro control unit 11 in accordance with an electronic signal inputted from the outside; an input device 95 may also be used, electrically connected to the micro-control unit 11, for the micro-control unit 11 to select a location table T1-T10 according to the control of the input device 95, wherein the input device 95 may be a button, a knob or a user operation interface.
The main technical features of the first embodiment are explained above, and the operation of the first embodiment is explained next.
Before the adjustment, the micro-control unit 11 usually selects the position tables T1 to T10, such as the fifth position table T5, with the plurality of position tables T1 to T10 being located at the center, and the micro-control unit 11 controls the derailleur 41 to align with the sixth tooth G6.
Then, as shown in fig. 2, the user directly visually observes whether the derailleur 41 is aligned with the sixth tooth G6, and if not, the micro-control unit 11 selects another position table T1-T10, and since the position tables T1-T10 are arranged sequentially with a difference in distance value, the micro-control unit 11 selects the sixth position table T6 or the position tables T7-T10 arranged in the later stages, so that the micro-control unit 11 can control the derailleur 41 to continuously move toward a position with a larger distance value, and the micro-control unit 11 can control the derailleur 41 to continuously move toward a position with a smaller distance value by selecting the fourth position table T4 or the position tables T1-T3 arranged in the earlier stages. Referring to fig. 2, derailleur 41 is not aligned with sixth tooth G6, but is located behind sixth tooth G6, so that micro-control unit 11 can select sixth position table T6 and control derailleur 41 to move to a position corresponding to the position information of sixth tooth G6 in position table T6 again, and as a result, derailleur 41 moves to an actual position aligned with sixth tooth G6 as shown in fig. 3, thereby completing the adjustment operation. Once the selected position tables T1-T10 allow the derailleur to be aligned with a tooth, the position information in the tables T1-T10 corresponds to each tooth.
During actual riding, when receiving a command to change a file or automatically determining that a gear shift should be performed, the ecu 11 performs a gear shift operation according to the selected position tables T1-T10, and drives the derailleur 41 to move to a corresponding position according to the position information of the corresponding tooth plates G1-G11 in the position tables T1-T10.
In addition, since the position information in the position tables T1-T10 directly corresponds to the tooth plates G1-G11, the micro control unit 11 directly refers to the selected position tables T1-T10 to drive when adjusting the position of the derailleur 41, so that the position of the derailleur 41 is integrally adjusted without the need of reusing a logic operation after each adjustment like the prior art, thereby simplifying the complicated process of the prior art requiring additional processing, having the effects of fast and saving computing energy, and being convenient and accurate in adjustment.
Referring again to FIGS. 4-5, a second preferred embodiment of the present invention provides a bicycle derailleur system 10' that is easily adjustable, which is generally similar to the first embodiment, except that:
the position information of each of the position tables T1 'to T10' is not only aligned with the center position of each of the teeth G1 'to G11', but also aligned with the center position of each of the teeth G1 'to G11', and includes an upper chain position for upper chain of each of the teeth G1 'to G11' and a lower chain position for lower chain of each of the teeth G1 'to G11', that is, each of the position information includes a center position, an upper chain position and a lower chain position, and the upper chain position of each of the position information is located before the center position and differs from the center position by a predetermined value, and the center position is located before the lower chain position and differs from the lower chain position by a predetermined value. These two predetermined values are the same in actual implementation. In fig. 5, the center position is shown as a center line, and the uplink position and the downlink position are shown as dashed lines for easy understanding.
For convenience of representation, in the second embodiment, only the position tables T3 'to T7' are represented as follows, and the other position tables are analogized according to the numerical difference between two position tables:
position table T3'
Position table T4'
Position table T5'
Position table T6'
Position table T7'
In operation, the second embodiment also selects a position table T1 'through T10' by the micro control unit 11 ', and then adjusts the position of the derailleur 41' according to the position table T1 'through T10'. The reason why the additional upper and lower chain positions of the second embodiment are mainly to make the gear shifting smoother is that, when the actual mechanism performs the upper gear shifting operation, the derailleur 41 ' usually not only shifts the chain (not shown) to the center position aligned with a certain tooth (e.g., the 6 th tooth G6 '), but also shifts the chain a little more forward, i.e., to the upper chain position, so that the chain can be engaged with the 6 th tooth G6 ' quickly and reliably; in the downshifting of the shifting operation, the derailleur 41 ' not only shifts the chain to the center position aligned with a tooth (e.g., the 6 th tooth G6 '), but also shifts the chain a little more backward, i.e., to the down position, to allow the chain to be engaged with the 6 th tooth G6 ' quickly and reliably.
As can be seen from the above, the second embodiment can make the shifting process smoother and more stable than the first embodiment.
Other technical features and effects of the second embodiment are substantially the same as those of the first embodiment, and will not be described again.
