[0024] Please refer to Figure 1 The present application provides an electronic transmission manual operation method, which is applied to the scenario that the front chain wheel is a double-disc chain wheel, the double-disc chain wheel includes a large disc and a small disc, and the electronic transmission manual operation method includes:

[0025] S101: acquiring key information issued according to user operation and analyzing the key information;

[0026] Specifically, the key information includes: first key information and second key information, when the user wants to perform the corresponding operation, only need to press the corresponding key, send the corresponding key information, when the corresponding key information is obtained, execute step S102, judge whether the key information is the first key information, wherein the first key information and the second key information can be respectively: left hand variable outer key information and left hand variable inner key information, or can be respectively: left hand variable inner key information and left hand variable outer key information, other implementation modes are also feasible, only need to set two keys on the hand variable to have the function of the first key and the second key respectively, strong adaptability.

[0027] S102: whether the key information is the first key information;

[0028] Specifically, if the key information is the first key information, execute step S103; if the key information is not the first key information (i.e. the key information is the second key information), execute step S107.

[0029] S103: obtain the position information of the front derailleur and analyze the position information;

[0030] S104: whether the front derailleur is in the large disc;

[0031] Specifically, if the front derailleur is in the large disc, execute step S105; if the front derailleur is not in the large disc (i.e. the front derailleur is in the small disc), execute step S106.

[0032] S105: execute the half-stop operation;

[0033] Wherein, before executing the half-stop operation, the position information of the rear derailleur is also needed to be obtained and analyzed; if the rear derailleur is in the normal zone, end the operation; if the rear derailleur is in the half-stop zone, execute the half-stop operation.

[0034] Specifically, when the rear derailleur is in the large disc normal zone, end the operation; when the rear derailleur is in the large disc inner half-stop zone, control the front derailleur to execute the half-stop operation inward; when the rear derailleur is in the large disc outer half-stop zone, control the front derailleur to execute the half-stop operation outward.

[0035] In a specific application scenario, taking a 12-speed flywheel as an example, if the rear derailleur is at the 6th flywheel from the outside to the inside, the operation is ended, that is, no operation is needed, at this time, the chain and the front derailleur are in a relatively parallel state; if the rear derailleur is at the flywheel position inside the 6th flywheel from the outside to the inside (that is, the rear derailleur is in the half-stop area inside the large disc), for example, the rear derailleur is at the 7th flywheel from the outside to the inside, or the rear derailleur is at the 8th flywheel from the outside to the inside, at this time, the chain is offset to the inside, so the front derailleur needs to be controlled to perform a half-stop operation to the inside; if the rear derailleur is at the flywheel position outside the 6th flywheel from the outside to the inside (that is, the rear derailleur is in the half-stop area outside the large disc), for example, the rear derailleur is at the 5th flywheel from the outside to the inside, at this time, the chain is offset to the outside, so the front derailleur needs to be controlled to perform a half-stop operation to the outside.

[0036] After determining the offset direction, the offset distance is determined, which includes: calculating the offset distance required by the front derailleur according to the position information of the rear derailleur, and performing a related half-stop operation according to the offset distance, wherein the farther the rear derailleur is offset from the normal area of the large disc, the farther the required offset distance is.

[0037] In a specific application scenario, taking a 12-speed flywheel as an example, if the rear derailleur is at the flywheel position inside the 6th flywheel from the outside to the inside, the offset distance is calculated, and the front derailleur is controlled to move to the inside according to the offset distance, and the farther the rear derailleur is offset from the position that makes the chain offset to the inside, the greater the offset distance is, wherein the offset distance is less than the offset distance when the large disc is replaced with the small disc.

[0038] If the rear derailleur is at the flywheel position outside the 6th flywheel from the outside to the inside, the offset distance is calculated, and the front derailleur is controlled to move to the outside according to the offset distance, the farther the rear derailleur is offset from the position that makes the chain offset to the outside, the greater the offset distance is, and the maximum offset distance is less than 10 mm, and the minimum offset distance is greater than 0.5 mm.

[0039] S106: performing a gear shifting operation;

[0040] Before performing the gear shifting operation, the embodiment further provides a judgment of whether the gear shifting operation can be performed, which includes: obtaining the position information of the rear derailleur; analyzing whether the gear shifting condition is met according to the position information of the rear derailleur and the position information of the front derailleur; if yes, performing the gear shifting operation, that is, replacing the front derailleur with the large disc; if not, ending the operation.

[0041] The judgment of whether the gear shifting operation can be performed in this embodiment is mainly for some special cases. For example, for some variable speed bicycles, the chain offset distance is small, so that the chain is located in the largest several sprockets, and cannot be hung on the large disc, that is, the gear shifting cannot be completed, or the chain is located in the largest several sprockets, and can be hung on the large disc, but at this time the chain is in an extremely offset state, the rotation efficiency is low, and the chain length will be stretched and the structure will change under long-term action, and the chain will be severely damaged. Therefore, in order to avoid the chain from not being hung or being severely damaged, the judgment condition of the small disc to the large disc in this embodiment can be set as: when the rear derailleur is in the largest several sprockets, the gear shifting operation cannot be performed, wherein the specific setting of which several largest sprockets is determined according to the specific situation.

[0042] S107: acquiring position information of the front derailleur and analyzing the position information;

[0043] S108: whether the front derailleur is in the large disc;

[0044] Specifically, if the front derailleur is in the large disc, step S110 is performed; if the front derailleur is not in the large disc (i.e., the front derailleur is in the small disc), step S109 is performed.

[0045] S109: performing half gear shifting operation;

[0046] Specifically, before performing the half gear shifting operation, the position information of the rear derailleur is also acquired and analyzed as in step S105; if the rear derailleur is in the normal zone, the operation is ended; if the rear derailleur is in the half gear shifting zone, the half gear shifting operation is performed.

[0047] Specifically, when the rear derailleur is in the small disc normal zone, the operation is ended; when the rear derailleur is in the small disc inner half gear shifting zone, the front derailleur is controlled to perform the half gear shifting operation inwardly; when the rear derailleur is in the small disc outer half gear shifting zone, the front derailleur is controlled to perform the half gear shifting operation outwardly.

[0048] In a specific application scenario, taking the 12-speed sprocket as an example, if the rear derailleur is in the 8th sprocket from the outside to the inside, the operation is ended, that is, no operation is needed, at this time the chain and the front derailleur are in a relatively parallel state; if the rear derailleur is in the inner sprocket position of the 8th sprocket from the outside to the inside (i.e., the rear derailleur is in the small disc inner half gear shifting zone), for example, the rear derailleur is in the 9th sprocket from the outside to the inside, at this time the chain is offset inwardly, therefore the front derailleur needs to be controlled to perform the half gear shifting operation inwardly; if the rear derailleur is in the outer sprocket position of the 8th sprocket from the outside to the inside (i.e., the rear derailleur is in the small disc outer half gear shifting zone), for example, the rear derailleur is in the 5th sprocket from the outside to the inside, at this time the chain is offset outwardly, therefore the front derailleur needs to be controlled to perform the half gear shifting operation outwardly.

[0049] After determining the offset direction, the next step is to determine the offset distance. The offset distance determination includes: calculating the required offset distance of the front derailleur based on the position information of the rear derailleur, and performing the relevant half-gear operation based on the offset distance. The further the rear derailleur is offset from the normal area of ​​the small chainring, the farther the required offset distance will be.

[0050] In a specific application scenario, taking a 12-speed cassette as an example, if the chain at the rear derailleur is in the inner position of the 8th cassette from the outside, the offset distance is calculated, and the front derailleur is controlled to move inward accordingly based on the offset distance. The more the chain at the rear derailleur is in the gear that makes the chain more inward, the greater the offset distance will be. The maximum offset distance is less than 20mm, and the minimum offset distance is greater than 0.5mm.

[0051] If the rear derailleur is in the outermost position of the 8th cassette from the outside, the offset distance is calculated, and the front derailleur is controlled to move outward accordingly based on the offset distance. The further out the chain is in the derailleur position, the greater the offset distance. The offset distance is less than the offset distance when changing from a small chainring to a large chainring.

[0052] S110: Perform a gear shift operation;

[0053] In this embodiment, before performing the shifting operation, a judgment is set to determine whether the shifting operation can be performed, including: obtaining the position information of the rear derailleur; analyzing whether the shifting conditions are met based on the position information of the rear derailleur and the position information of the front derailleur; if they are met, the shifting operation is performed, that is, the front derailleur is changed from the large chainring to the small chainring; if they are not met, the operation is terminated.

[0054] This embodiment sets the judgment on whether a shifting operation can be performed mainly to address some special situations. For example, for some multi-speed bicycles, the chain offset distance is small, so when the chain is on the smallest of the freewheels, it cannot engage the small chainring, i.e., shifting cannot be completed. Or, when the chain is on the smallest of the freewheels, it can engage the small chainring, but at this time the chain is in an extremely offset state, its rotation efficiency is low, and under long-term use, the chain length will be stretched, the structure will change, and the chain will be severely damaged. Alternatively, if the chain length is too long, when the chain is on the small chainring and small freewheel, there is a risk that the guide wheel of the rear derailleur will come into contact with the freewheel. Therefore, to avoid the above situations, this embodiment can also set the judgment condition for shifting from a large chainring to a small chainring as follows: when the rear derailleur is on the smallest of the freewheels, shifting operation cannot be performed. The specific few smallest freewheels are determined according to the specific situation.

[0055] This embodiment enhances the user's engagement with half-gear operation by setting two buttons, allowing the user to manually complete the half-gear operation, thus improving the user's sense of control and experience. At the same time, when no button input is received from the user, there is no need to continuously obtain the position status of the front and rear derailleurs, resulting in low power consumption and long battery life. Moreover, this method is applicable to currently available derailleur bicycles with a double-chainring front sprocket, requiring no structural modifications and demonstrating strong applicability.
