The pushing portion 2803 abuts against the pushed portion 2103 of the positioning pawl 210 and the pushed portion 2203 of the stopping pawl 220. In the present embodiment, the elastic biasing element 260 is also used for applying a force to move the pushed portion 2103 of the positioning pawl 210 toward the pushing portion 2803 of the translating element 280, and the elastic biasing element 270 is also used for applying a force to move the pushed portion 2203 of the stopping pawl 220 toward the pushing portion 2803 of the translating element 280. Thus, the pushed portion 2103 of the positioning pawl 210 and the pushed portion 2203 of the stopping pawl 220 normally abut against the abutting portion 2803 of the translating element 280 without the positioning pawl 210 and the stopping pawl 220 being subjected to external forces other than the elastic biasing members 260, 270.

In the present embodiment, the bicycle shift operating device 1 further includes a plug 330, and the plug 330 has a positioning protrusion 3301. The backstop lever 130 has a cable assembly hole 1302 and a positioning hole 1303. The positioning holes 1303 are recessed from the sidewall surfaces 1304 of the cable assembly holes 1302. The cable assembling hole 1302 is used for installing a cable on the wire pulling wheel 21, the plug body 330 is installed on the cable assembling hole 1302, and the positioning protrusion 3301 of the plug body 330 is engaged with the positioning hole 1303, so as to fix the plug body 330 on the cable assembling hole 1302. However, the plug body 330 and the cable assembly hole 1302 are optional elements and structures; in other embodiments, the bicycle shift operating device can be free of a plug body and the downshift lever can be free of a cable assembly hole.

Next, referring to fig. 8 in conjunction with the previous fig. 1, fig. 8 is a bottom view of the bicycle shift operating device of fig. 2 with the base removed.

In the present embodiment, the assembling portion 31 of the gearshift lever 30 has a groove 312, and the groove 312 is located in a portion of the assembling portion 31 of the gearshift lever 30 located in the accommodating space 15 of the housing 10. In addition, the bicycle shift operating device 1 further includes a screw 300. The stop member 40 is made of iron, for example. The stopping member 40 is located on a side of the lower assembling plate 12 away from the upper assembling plate 16, and the stopping member 40 includes an assembling portion 41, a first arm portion 42 and a second arm portion 43. The first arm portion 42 and the second arm portion 43 extend in two different directions from the assembling portion 41. The screw 300 is inserted through the assembling portion 41 and locked to the lower assembling plate 12, so that the assembling portion 41 is pivotally mounted on the lower assembling plate 12 through the screw 300. The stop member 40 is pivotable between a first position P1 and a second position P2. In detail, as shown in fig. 8, when the stopping member 40 is located at the first position P1, the integral stopping member 40 is located outside the groove 312 of the assembling portion 31 of the gearshift lever 30. On the other hand, referring to fig. 13, when the stopping member 40 is at the second position P2, a portion of the second arm 43 is located in the groove 312 of the assembling portion 31 of the shift lever 30.

In this embodiment, the base 11 has a sliding slot 112 communicating with the accommodating space 15, the first arm 42 of the stopping member 40 has a protruding portion 421, and the bicycle shift operating device 1 further includes a cap 310. The protrusion 421 is movably located on the sliding slot 112 and protrudes out of the base 11. The cap body 310 is mounted on the protrusion 421. By sliding the cap body 310, the integral stopping member 40 can be driven by the protrusion 421 to pivot between the first position P1 and the second position P2.

It should be noted that cap 310 is an optional element; in other embodiments, the bicycle shift operating device can omit the cap. With such a configuration, the projection 421 of the second arm 43 can be directly operated to bring the stopper member to pivot. On the other hand, in another embodiment, the second arm may not have a projection. In such a configuration, the stop member may be pivoted electrically.

The magnetically attractive member 50 may also be referred to as a torque applying member. The magnetic member 50 includes a magnet 51 and a positioning element 52. The magnet 51 is, for example, a ring body. The positioning member 52 is, for example, a ferrous screw. The positioning member 52 includes a head portion 521 and a body portion 522, wherein the head portion 521 is wider than the body portion 522. The body 522 of the positioning member 52 is inserted into the magnet 51 and locked to the lower assembling plate 12, so that the magnet 51 is located on the side of the lower assembling plate 12 away from the upper assembling plate 16 and is sandwiched between the head 521 of the positioning member 52 and the lower assembling plate 12. The head 521 of the positioning member 52 is located between the first arm 42 and the second arm 43 of the stop member 40.

In the present embodiment, the magnetic member 50 is used for positioning the stopping member 40 at the first position P1 when the stopping member 40 is located at the first position P1, and for positioning the stopping member 40 at the second position P2 when the stopping member 40 is located at the second position P2. In detail, as shown in fig. 8, when the stopping member 40 is located at the first position P1, the first arm 42 abuts against the head 521 of the positioning element 52, and the magnet 51 attracts the first arm 42 through the positioning element 52, so as to locate the stopping member 40 at the first position P1. That is, when the stopping member 40 is located at the first position P1, the first arm 42 abuts against the head 521 of the positioning member 52, and the magnet 51 provides a magnetic attraction force to the first arm 42 through the positioning member 52, so as to apply a moment to the stopping member 40 in a pivoting direction (e.g., a first pivoting direction D3 in fig. 8) away from the second position P2. On the other hand, referring to fig. 13, when the stopping member 40 is located at the second position P2, the second arm portion 43 abuts against the head portion 521 of the positioning element 52, and the magnet 51 attracts the second arm portion 43 through the positioning element 52, so as to locate the stopping member 40 at the second position P2. That is, when the stopping member 40 is located at the second position P2, the second arm portion 43 abuts against the head portion 521 of the positioning member 52, and the magnet 51 provides a magnetic attraction force to the second arm portion 43 through the positioning member 52, so as to apply a moment to the stopping member 40 in a pivoting direction (e.g., the second pivoting direction D4 in fig. 13) away from the first position P1.

In the present embodiment, the magnetic poles of the two opposing portions of the magnet 51 in the axial direction are different. In detail, a portion of the magnet 51 adjacent to the head 521 of the positioning element 52 is one of an N pole and an S pole, and another portion of the magnet 51 away from the head 521 of the positioning element 52 is the other of the N pole and the S pole. Accordingly, the magnet 51, in cooperation with the head 521 of the positioning element 52 located between the first arm 42 and the second arm 43, can provide a strong magnetic attraction force to the first arm 42 or the second arm 43 of the stopping member 40, so as to ensure that the stopping member 40 is stably positioned at the first position P1 or the second position P2.

However, the retainer 52 is an optional component, and in other embodiments, the magnetically attractive member may be free of a retainer. In this case, the magnet may be extended to have a portion between the first arm portion 42 and the second arm portion 43. Therefore, the magnet can also apply a moment in the pivoting direction of the stopping member 40 away from the second position P2 when the stopping member 40 is located at the first position P1 to position the stopping member at the first position P1, and apply a moment in the pivoting direction of the stopping member 40 away from the first position P1 when the stopping member is located at the second position P2 to position the stopping member at the second position P2.

On the other hand, the magnet is not limited to providing torque to the stopper member 40; in other embodiments, the magnetic member may be located directly above or below the first arm of the stopping member when the stopping member is located at the first position to directly attract the first arm, and located directly above or below the second arm of the stopping member when the stopping member is located at the second position to directly attract the second arm. Thus, even if the magnet does not provide torque to the stopping member, the magnetic member can still position the stopping member.

In the present embodiment, with the stop member 40 located at the first position P1, a user can selectively shift the transmission into one gear or sequentially shift a plurality of gears by one action of shifting the shift lever 30, which will be described in detail below.

Referring to fig. 9 and 10, fig. 9 is a schematic sectional view illustrating the actuation of the shift lever of fig. 7, and fig. 10 is a schematic bottom view illustrating the actuation of the shift lever of fig. 8. Fig. 9 and 10 omit or truncate parts of the components to avoid obscuring the shift operating operation of the bicycle shift operating device.

First, as shown in fig. 9, the gearshift lever 30 may be pivoted from the initial position IP (shown in fig. 7) in the first direction D1. Once the kick lever 30 is pivoted, the abutment 1902 of the kick pawl 190 disengages from the abutment 122 of the lower package plate 12, and the resilient biasing member 180 urges the engagement portion 1903 of the kick pawl 190 toward the first ratchet 22 to engage the engagement portion 1903 of the kick pawl 190 with the first ratchet 22. Then, when the engaging portion 1903 of the engaging pawl 190 is engaged with the first ratchet wheel 22 and continues to pivot in the first direction D1, the engaging portion 1903 of the engaging pawl 190 drives the first ratchet wheel 22, the wire pulling wheel 21 and the second ratchet wheel 23 to rotate in the first direction D1, so that the second ratchet wheel 23 pushes away the engaging portion 2102 of the positioning pawl 210, the engaging portion 2102 of the positioning pawl 210 goes over the tooth slot 232 of the positioning pawl 210 engaged previously, and then engages with the next tooth slot 232 of the second ratchet wheel 23 under the elastic force of the elastic biasing member 260 and simultaneously collides with the second ratchet wheel 23. In this way, the pulley 21 is rotated by an angle in the first direction D1, and the transmission is shifted by one gear through the cable. Moreover, the user can use the sound feedback generated by the impact to judge the successful gear-in.

It is noted that, as can be seen from fig. 9, during the pivoting of the first ratchet wheel 22 in the first direction D1, the engaging portion 2202 of the stopping pawl 220 is maintained separated from the first ratchet wheel 22 by the biasing force of the resilient biasing member 270 (shown in fig. 3), so that the engaging portion 2202 of the stopping pawl 220 does not block the rotation of the first ratchet wheel 22.

Next, as shown in fig. 9, after the stop member 40 is located at the first position P1 and the shift lever 30 has been shifted from the initial position IP to actuate the transmission into one shift position, the user may release the shift lever 30 such that the shift lever 30 is operated to shift the transmission into one shift position only, or the shift lever 30 is pivoted in the first direction D1 to allow the shift lever 30 to be operated to shift the transmission into a plurality of shift positions.

In the case where the user selects to continue pivoting the shift lever 30 in the first direction D1, the shift pawl 190 continuously rotates the pulley 21, continuously pulls the cable, and the transmission continuously shifts. Referring to fig. 11 and 12, fig. 11 is a schematic cross-sectional view illustrating the shift lever of fig. 9 being continuously actuated. Fig. 12 is a bottom schematic view of the shifter lever of fig. 10 continuing to be actuated. Once the detent seat 32 of the gearshift lever 30 abuts against the second inner wall surface 1212 of the through slot 121 of the lower assembly plate 12, the gearshift lever 30 is at a limit position LP and cannot pivot in the first direction D1. In the present exemplary embodiment, after the gearshift lever 30 has pivoted from the initial position IP to the extreme position LP, the transmission can be shifted into five gears, for example, but not limited thereto. In other embodiments, the distance between the second inner wall surface and the first inner wall surface of the through groove of the lower assembly plate can be adjusted, so that pivoting the gear advancing pawl from the initial position IP to the limit position LP can advance the transmission into more or less than five gears.

When the transmission is shifted, the shift lever 30 can be released, and the elastic force of the elastic biasing member 170 forces the shift lever 30 to return to the initial position IP. During the movement of the shift lever 30 toward the initial position IP, the shift pawl 190 moves along with the shift lever 30 and disengages from the first ratchet 22. At this time, since the engaging portion 2102 of the positioning pawl 210 is engaged with the tooth groove 232 of the second ratchet wheel 23, even if the capstan 21 receives the elastic force applied by the elastic biasing member 160, the capstan 21 cannot rotate in the second direction D2 and is maintained at the final position by the catch pawl.

On the other hand, in the present embodiment, the user can pivot the stopping member 40 from the first position P1 to the second position P2, so that one operation of dialing the shift lever 30 can only make the transmission shift one shift position, which will be described in detail below.

Please refer to fig. 13 and 14. Fig. 13 is a bottom view of the stop member of fig. 8 in a second position. Fig. 14 is a bottom view of the shift lever of fig. 13 actuated.

When the stopping member 40 is located at the second position P2, since the second arm 43 of the stopping member 40 is located in the groove 312 of the assembling portion 31 of the shift lever 30, the shift lever 30 is stopped by the second arm 43 during the pivoting process from the initial position IP to the first direction D1, and can only pivot to the middle position MP between the initial position IP and the limit position LP, and cannot further pivot from the middle position MP to the limit position LP. At this time, the shift lever 30 can only shift the transmission to the first gear by the angle of rotation of the pulley 21 (shown in fig. 9) carried by the shift pawl 190. That is, when the stopping member 40 is located at the second position P2, the second arm 43 of the stopping member 40 limits the pivoting angle of the gearshift lever 30, and each operation of the gearshift lever 30 can only shift the transmission to the first gear, but the present invention is not limited thereto. In other embodiments, each operation of the shift lever 30 can selectively shift the transmission into only one shift position or two shift positions in succession with the stop member in the second position by increasing the length of the recess.

In the present embodiment, the transmission shifter 30 can be pivoted between the initial position IP and the limit position LP by the stopping member 40 in the first position P1, and the transmission shifter 30 can only be pivoted between the initial position IP and the middle position MP by the stopping member 40 in the second position P2, so that the pivotable angle range of the transmission shifter 30 can be adjusted, and the bicycle shift control device 1 can meet the requirements of different users.

Further, by the configuration of the magnetically attracting member 50 (torque applying member), it is possible to position the stopping member 40 at the first position P1 when the stopping member 40 is at the first position P1, or to position the stopping member 40 at the second position P2 when the stopping member 40 is at the second position P2. Thus, the bicycle shift operating device 1 can achieve the effect that the pivotable angle range of the shift lever 30 can be adjusted by simple component and structural configuration.

Next, the operation of the reverse lever 130 will be described below. Referring to fig. 15 to 17, fig. 15 to 17 are schematic cross-sectional views illustrating the operation of the reverse shift lever.

In detail, as shown in fig. 16, the shift lever 130 is shifted along the first direction D1, the shift lever 130 pushes the translation element 280, the pushing portion 2803 pushes the pushed portion 2103 of the positioning pawl 210 and the pushed portion 2203 of the stopping pawl 220, the engaging portion 2102 of the positioning pawl 210 is separated from the tooth space 232 of the second ratchet wheel 23, and the engaging portion 2202 of the stopping pawl 220 is engaged with the tooth space 222 of the first ratchet wheel 22, so that the second ratchet wheel 23, the pulley 21 and the first ratchet wheel 22 are stopped by the stopping pawl 220 after rotating together in the second direction D2 by the elastic biasing member 160.

In the process that the shift lever 130 is shifted along the second direction D2, the two limiting protrusions 1622 of the upper assembling plate 16 are respectively spaced apart from the two recess grooves 2802 of the translating member 280, so even if the translating member 280 is pushed by the shift lever 130, the two recess grooves 2802 of the translating member 280 are not aligned with the two limiting protrusions 1622, thereby preventing the translating member 280 from being separated from the upper assembling plate 16.

Then, as shown in fig. 17, when the user releases the shift lever 130, the force of the shift lever 130 pushing against the translation member 280 is removed, so that the elastic force of the elastic biasing member 290 drives the translation member 280 to return to the original position, and also forces the shift lever 130 to return to the original position. Meanwhile, the pushed portion 2103 of the positioning pawl 210 and the pushed portion 2203 of the stopping pawl 220 are no longer pushed by the pushing portion 2803 of the translating member 280, so the engaging portion 2202 of the stopping pawl 220 is disengaged from the tooth slot 222 of the first ratchet wheel 22 by the elastic force of the elastic biasing member 270, and the engaging portion 2102 of the positioning pawl 210 is engaged with the next tooth slot 232 of the second ratchet wheel 23 by the elastic force of the elastic biasing member 260, so that the second ratchet wheel 23, the wire pulling wheel 21 and the first ratchet wheel 22 are stopped by the positioning pawl 210 after rotating by an angle in the second direction D2 under the action of the elastic biasing member 160. Thus, after the downshift lever 130 is shifted from the initial position and then returned to the initial position, the rotation of the pulley 21 in the second direction D2 releases the cable, and the transmission is shifted to the first gear.

It should be noted that, in the process of the shift lever 130 being shifted from the initial position and then returning to the initial position, after one of the engaging portion 2102 of the positioning pawl 210 and the engaging portion 2202 of the stopping pawl 220 is disengaged from the corresponding ratchet wheel, the other one is immediately engaged with the corresponding ratchet wheel, so that the rotation of the pulley 21 in the second direction D2 through too many angles can be avoided, and the transmission is ensured not to be shifted for multiple gears at one time.

Next, referring to fig. 18, fig. 18 is a perspective view of the bicycle shift operating device with the base removed, according to the second embodiment of the present invention.

The bicycle shift operating device 1a of the present embodiment is similar to the bicycle shift operating device 1 of fig. 1 to 17, and also includes a housing 10, a gear adjustment assembly 20 (as shown in fig. 4), a shift lever 30 (a gear operating member), a stopping member 40, and a magnetic member 50a (a torque applying member), which are different from each other mainly in the arrangement position of the magnetic member, so the arrangement position of the magnetic member 50a is generally described below, and please refer to the description of the bicycle shift operating device 1 of fig. 1 to 17 in the above paragraphs for the structures of other elements and the connection relationship between these elements, which will not be described again.

In this embodiment, the magnetic member 50a also includes a magnet 51a and a positioning element 52a. The magnet 51a is provided to the lower assembly plate 12 of the case 10 through the stopper member 40. Specifically, the magnet 51a is stacked on the assembling portion 41 of the stopper member 40 and located on the side of the assembling portion 41 away from the lower assembling plate 12, and the screw 300 is inserted through the magnet 51a and the assembling portion 41 and locked to the lower assembling plate 12, so that the magnet 51a is held between part of the screw 300 and the assembling portion 41. However, in other embodiments, the magnet may be located between the assembling portion of the stopper member and the lower assembling plate, or embedded in the assembling portion. The positioning piece 52a is fixed to the lower assembling plate 12 and is located between the first arm portion 42 and the second arm portion 43 of the stopper member 40.

In the present embodiment, the positioning element 52a and the stopping member 40 are both made of iron. As shown in fig. 18, when the stopping member 40 is located at the first position P1, the magnet 51a attracts the positioning member 52a via the first arm 42, so as to position the stopping member 40 at the first position P1. That is, when the stopping member 40 is located at the first position P1, the first arm 42 abuts against the positioning member 52a, the magnet 51a provides a magnetic attraction between the first arm 42 and the positioning member 52a, and a moment is applied to the stopping member 40 in a pivoting direction (e.g., the first pivoting direction D3) away from the second position P2 (shown in fig. 19) to position the stopping member 40 at the first position P1.

Next, referring to fig. 19, fig. 19 is a perspective view of the stopping member of fig. 18 at a second position. When the stopping member 40 is located at the second position P2, the magnet 51a attracts the positioning element 52a through the second arm 43, so as to position the stopping member 40 at the second position P2; that is, when the stopping member 40 is located at the second position P2, the second arm 43 abuts against the positioning element 52a, the magnet 51a provides a magnetic attraction between the second arm 43 and the positioning element 52a, and a moment is applied to the stopping member 40 in a pivoting direction (e.g., the second pivoting direction D4) away from the first position P1, so as to position the stopping member 40 at the second position P2.

Note that the positioning piece 52a is not limited to be interposed between the first arm portion 42 and the second arm portion 43; in other embodiments, when the stop member is located at the first position P1, the positioning member may be located between the first arm and the lower assembling plate to position the first arm; when the stop member is located at the second position, the positioning member may be located between the second arm and the lower assembling plate to position the second arm. Under such a configuration, the magnetically attractive member does not provide a moment to the stop member, and the magnetically attractive member can still position the stop member.

Next, referring to fig. 20, fig. 20 is a bottom view of the bicycle shift operating device with the base removed in accordance with the third embodiment of the present invention.

The bicycle shift operating device 1b of the present embodiment is similar to the bicycle shift operating device 1 of fig. 1 to 17, and also includes a housing 10, a gear adjusting assembly 20, a shift lever 30 (gear operating member), a stopping member 40b and a torque applying member, and the main difference between the two components is the stopping member and the torque applying member, so the stopping member 40b and the torque applying member are generally described below, and please refer to the description of the bicycle shift operating device 1 of fig. 1 to 17 in the above paragraphs for the structure of other components and the connection relationship between these components, and the description is omitted here.

In the present embodiment, the stopping member 40b includes an assembling portion 41b, a first arm portion 42b, a second arm portion 43b and a third arm portion 44b. The first arm portion 42b, the second arm portion 43b, and the third arm portion 44b extend from the assembling portion 41b in three different directions, and the assembling portion 41b is pivotably attached to the lower assembling plate 12 of the case 10.

In this embodiment, the bicycle shift operating device 1 further includes a positioning member 320b. The positioning member 320b is a screw, for example. The positioning member 320b is fixed to the lower assembling plate 12 of the housing 10. The positioning piece 320b and the third arm portion 44b of the stopping member 40b are located at opposite sides of the assembling portion 41b, respectively, and the positioning piece 320b is also located between the first arm portion 42b and the second arm portion 43 b.

The torque application member is, for example, a spring 50b. The spring 50b is, for example, an extension spring. One end of the spring 50b is fixed to the lower assembling plate 12 of the housing 10 by the positioning piece 320b, and the other end of the spring 50b is fixed to the third arm 44b of the stopping member 40 b.

As shown in fig. 20, when the stopping member 40b is located at the first position P1, the first arm 42b of the stopping member 40b abuts against the positioning member 320b, and the force (indicated by the arrow F) exerted by the spring 50b on the stopping member 40b deviates from the pivot axis a of the stopping member 40b, so that a moment in a pivoting direction (e.g., the first pivoting direction D3) away from the second position P2 (please refer to fig. 22) is generated for the stopping member 40, so that the first arm 42b is kept abutting against the positioning member 320b, and the stopping member 40b is located at the first position P1.

With the stopper member 40 located at the first position P1, the pivotal stopper member 40b may be urged to pivot the stopper member 40b toward the second position P2 against the elastic force of the spring 50b. In the process, the third arm 44b of the stopping member 40b gradually elongates the spring 50b, so that the elastic potential energy stored in the spring 50b gradually increases.

Next, referring to fig. 21, fig. 21 is a bottom view of the stopping member of fig. 20 at the equilibrium position. When the stop member 40 pivots to a balanced position BP between the first position P1 and the second position P2, the length L of the spring 50b is longer than the length L1 when the stop member 40 is in the first position P1, and the force (as indicated by arrow F) exerted by the spring 50b on the stop member 40b passes through the pivot axis a of the stop member 40b without exerting a moment on the stop member 40 b.

In such a state, the stop member 40 is in an unstable equilibrium state, and as long as the stop member 40 is slightly rotated toward the second position P2, the force exerted by the spring 50b on the stop member 40b is immediately offset from the pivot axis a of the stop member 40b, and a moment is exerted on the stop member 40b to pivot toward the second position P2, so that the stop member 40 automatically pivots to the second position P2 by the pull of the spring 50b during the shortening of the spring 50b. As such, the stop member 40b does not need to be manually moved all the way from the balance position BP to the second position P2.

Referring to fig. 22, fig. 22 is a bottom view of the stop member of fig. 20 in a second position. When the stopping member 40b is located at the second position P2, the second arm 43b of the stopping member 40b abuts against the positioning member 320b, and the length L2 of the spring 50b is smaller than the length L of the stopping member 40b when it is located at the balance position BP. Since the force (indicated by the arrow F) applied by the spring 50b to the stop member 40b is offset from the pivot axis a of the stop member 40b, the spring 50b continuously applies a moment to the stop member 40b in the pivoting direction (e.g., the second pivoting direction D4) away from the first position P1, so that the second arm 43b is kept abutting against the positioning member 320b, and the stop member 40b is positioned in the second position P2.

It should be noted that the spring 50b is not limited to the extension spring. In other embodiments, the spring may be a compression spring. In such a case, the third arm of the stop member needs to be interposed between the assembling portion of the stop member and the positioning member. The length of the compression spring at the equilibrium position is smaller than the length of the compression spring at the first position and the length of the compression spring at the second position, so that the stop component of the compression spring at the equilibrium position enables the spring to store larger elastic potential energy.

Please refer to fig. 23 to fig. 26. Fig. 23 is a perspective view of a bicycle shift operating device in accordance with a fourth embodiment of the present invention. Fig. 24 is a partially exploded view of fig. 23. Fig. 25 is a schematic cross-sectional view of fig. 23. Fig. 26 is a bottom view of fig. 23.
