Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle gear transmission technology, and in particular to a novel right-hand adjustable shifter gearbox. Background Technology
[0002] Shifters are used for changing gears on bicycles. When shifting gears, the shifter adjusts the tension of the shift cable by moving the upshift or downshift lever, which in turn adjusts the position of the front and rear derailleurs. This allows the chain to mesh with different gears on the front and rear sprockets, thus enabling speed adjustment. Conventional bicycle shifters have an upshift lever and a downshift lever, using two sets of levers to shift up and down. This complex structure increases the number of parts and complicates the assembly process.
[0003] Therefore, there is an urgent need for a new type of right-hand speed-adjusting shifter that can complete a gear shift or downshift using a set of levers, with a simple structure and relatively fewer parts. Utility Model Content
[0004] The purpose of this invention is to provide a novel right-hand adjustable shifter, which solves the technical problems of existing technologies that require two sets of levers for shifting and reversing, resulting in complex structures and an increased number of parts. The preferred technical solutions provided by this invention offer numerous technical advantages, which are detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This utility model provides a novel right-hand adjustable shifter, including a main seat mounted on the handlebars, an upper cover mounted on the main seat, a pointer rotatably connected inside the upper cover, and a handlebar rotatably connected to the main seat via a main shaft, and further including:
[0007] The forward / reverse seat and the forward / reverse seat torsion spring are provided. The forward / reverse seat is rotatably connected to the main shaft. The edge of the handle lever is limited on the forward / reverse seat. The forward / reverse seat torsion spring is installed between the forward / reverse seat and the main seat.
[0008] The gear torque assembly and the anti-reset assembly are provided. The gear torque assembly is mounted on the main shaft and connected to the gear shift cable. The anti-reset assembly is mounted on the main seat and is engaged with the gear torque assembly in a clockwise direction along the main shaft.
[0009] The self-resetting pawl is installed on the side of the forward / reverse seat and is engaged with the gear torque assembly in a clockwise direction along the main shaft. By rotating the handle lever counterclockwise, the self-resetting pawl drives the gear torque assembly to rotate. By rotating the reset handle lever clockwise, the self-resetting pawl disengages from the gear torque assembly and pushes the anti-reset self-resetting assembly to release the gear torque assembly in a clockwise direction.
[0010] Preferably, the gear torque assembly includes:
[0011] The gear shift tooth and the spool are coaxially fixedly connected and sleeved on the main shaft; the spool is connected to the gear shift cable.
[0012] A torsion spring is installed between the spool and the main shaft. The teeth on the gear shift gear are engaged with the anti-reset self-resetting assembly in a clockwise direction along the main shaft and with the self-resetting pawl in a clockwise direction along the main shaft.
[0013] Preferably, the back-stop self-resetting component includes:
[0014] A backstop pawl, which is rotatably connected to the main seat;
[0015] A torsion spring for the anti-reverse pawl is installed at the rotatable connection between the anti-reverse pawl and the main seat. The anti-reverse pawl and the gear tooth are arranged to abut against each other in a clockwise direction along the main shaft.
[0016] Preferably, the anti-reverse claw includes:
[0017] The first claw, the second claw, and the third claw are fixedly connected and distributed circumferentially. The third claw is located clockwise near the main shaft, and the first claw is located counterclockwise near the main shaft. The second claw is pushed and the gear teeth are released clockwise by rotating the reset handle lever clockwise.
[0018] Preferably, the gear torque assembly further includes:
[0019] A protrusion is fixedly connected to the side of the advance / retractor and is located near the second claw. The protrusion is in a counterclockwise direction relative to the second claw and close to the spindle.
[0020] Preferred options also include:
[0021] A lever is fixedly connected to the side of the handle lever and axially inserted into the side of the advance / retract seat.
[0022] Preferably, the self-resetting claw includes:
[0023] The pawl is rotatably connected to the side of the advance / retract seat and engages with the clockwise side of the teeth on the gear shift plate.
[0024] A ratchet pawl torsion spring is installed at the rotatable connection between the ratchet pawl and the forward / reverse seat.
[0025] Preferred options also include:
[0026] A pull plate, the first end of which is fixedly sleeved on the main shaft, and the second end of which is sleeved at the rotation center between the anti-reverse pawl and the main seat.
[0027] In the technical solution provided by this utility model, the main function of the anti-reset component is to prevent the gear torque component from rotating clockwise, that is, to prevent the gear torque component from disengaging. The main function of the self-reset pawl is to drive the gear torque component to rotate counterclockwise when the handle lever and the shift seat are rotated counterclockwise, thereby realizing gear engagement. The self-reset pawl, gear torque component, and anti-reset component rotate when pushed by an external force, and automatically reset when the external force disappears. The main function of the shift seat is: firstly, when engaging gear, manually rotating the handle lever counterclockwise pushes the shift seat to rotate counterclockwise, thereby driving the gear shift through the self-reset pawl. The first method involves manually rotating the torque assembly counterclockwise by one gear position. After releasing the lever, the lever is reset by the torsion spring in the shifting seat, completing the shifting. The second method involves manually rotating the lever clockwise, pushing the shifting seat clockwise. At this time, the self-resetting pawl disengages from the gear torque assembly via the self-resetting stop assembly. The lever pushes the self-resetting stop assembly clockwise by a certain angle, releasing the gear torque assembly. The gear torque assembly then continues to be blocked by the self-resetting stop assembly after rotating clockwise by a certain angle. After releasing the lever, the lever is reset by the torsion spring in the shifting seat, and the self-resetting pawl re-engages with the gear torque assembly, completing the shifting. Overall, this application uses a single lever; rotating the lever counterclockwise or clockwise and releasing it completes one shifting (shifting or shifting). The structure is simple, the number of parts is relatively reduced, and the assembly process is simplified. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0036] refer to Figure 1-5 A specific embodiment of this utility model provides a novel right-hand adjustable shifter, including a main seat 1 mounted on the handlebars, an upper cover 12 mounted on the main seat 1, a pointer 10 rotatably connected inside the upper cover 12, and a handlebar lever 9 rotatably connected to the main seat 1 via a main shaft 2, and further including:
[0037] The forward / reverse seat 3 and the forward / reverse seat torsion spring are rotatably connected to the main shaft 2. The edge of the handle lever 9 is limited on the forward / reverse seat 3. The forward / reverse seat torsion spring is installed between the forward / reverse seat 3 and the main seat 1.
[0038] The gear torque assembly and the anti-reset assembly are mounted on the main shaft 2 and connected to the gear shift cable. The anti-reset assembly is mounted on the main seat 1 and is engaged with the gear torque assembly in a clockwise direction along the main shaft 2.
[0039] The self-resetting pawl is installed on the side of the forward / reverse seat 3 and is engaged with the gear torque assembly in the clockwise direction along the main shaft 2. By rotating the handle lever 9 counterclockwise, the self-resetting pawl drives the gear torque assembly to rotate. By rotating the reset handle lever 9 clockwise, the self-resetting pawl disengages from the gear torque assembly and pushes the anti-reset self-resetting assembly to release the gear torque assembly in the clockwise direction.
[0040] Conventional bicycle shifters have shift levers for both upshifting and downshifting, resulting in a complex structure that increases the number of parts and complicates the assembly process. In this application, the main function of the anti-reset component is to prevent the gear torque assembly from rotating clockwise, i.e., to prevent it from downshifting. The main function of the self-resetting pawl is to drive the gear torque assembly to rotate counterclockwise when the shift lever 9 and the shift / reset seat 3 are rotated counterclockwise, thus achieving upshifting. The self-resetting pawl, gear torque assembly, and anti-reset component rotate when pushed by an external force, and automatically reset themselves after the external force disappears. The main function of the shift / reset seat 3 is: firstly, when upshifting, manually rotating the shift lever 9 counterclockwise pushes the shift / reset seat 3 to rotate counterclockwise, which in turn drives the gear torque assembly counterclockwise via the self-resetting pawl. When shifting gears, after releasing the lever 9, the lever 9 returns to its original position via the forward / reverse seat 3 under the action of the torsion spring, completing the shifting. Secondly, when shifting down, manually rotating the lever 9 clockwise pushes the forward / reverse seat 3 clockwise. At this time, the self-resetting pawl disengages from the gear torque component via the anti-resetting component. The lever 9 pushes the anti-resetting component to rotate clockwise by a certain angle, releasing the gear torque component. The gear torque component then rotates clockwise by a certain angle and continues to be blocked by the anti-resetting component. After releasing the lever 9, the lever 9 returns to its original position via the forward / reverse seat 3 under the action of the torsion spring, and the self-resetting pawl re-engages with the gear torque component, completing the shifting. Overall, this application uses a set of levers 9; rotating the lever 9 clockwise or counterclockwise and releasing it completes one shifting or shifting operation. The structure is simple, the number of parts is relatively reduced, and the assembly process is simplified.
[0041] In the initial state, i.e., the lowest gear, the shifting seat torsion spring is in a free state. Manually moving the handle lever 9 counterclockwise along the main shaft 2 once is a shifting operation. During this process, the handle lever 9 pushes the shifting seat 3 to rotate counterclockwise, and the shifting seat torsion spring generates a restoring force. Manually moving the handle lever 9 clockwise is a shifting operation. At this time, the handle lever 9 pushes the shifting seat 3 to rotate clockwise, and the shifting seat torsion spring generates a restoring force. Specifically, during the shifting operation, the edge of the handle lever 9 pushes the shifting seat 3, which drives the gear torque assembly to rotate counterclockwise through the self-resetting pawl. Since the anti-resetting self-resetting assembly and the gear torque assembly are engaged in a clockwise direction along the main shaft 2, each time the gear torque assembly rotates counterclockwise by one gear, it is blocked by the anti-resetting self-resetting assembly to prevent shifting. After releasing the handle lever 9... When shifting gears, the torque component is blocked by the self-resetting anti-reverse component. The shifting seat 3 drives the self-resetting claw to reset and lock the torque component. When shifting down in a high gear, the edge of the lever 9 pushes the shifting seat 3, which in turn pushes the self-resetting anti-reverse component to rotate clockwise. The self-resetting claw disengages from the torque component, releasing one gear position. At the same time, the torque component is blocked by the self-resetting anti-reverse component to prevent continuous downshifting. After releasing the lever 9, the torque component continues to be blocked by the self-resetting anti-reverse component. The shifting seat 3 resets and drives the self-resetting claw to lock the torque component again. After shifting up or down, the lever 9 is released. Under the rebound force of the shifting seat torsion spring, the lever 9 returns to its initial state through the shifting seat 3. The self-resetting claw returns to its initial state and locks with the torque component.
[0042] Further optimization of the design includes the following gear torque component:
[0043] The gear shifting gear 7 and the spool 8 are coaxially fixedly connected and sleeved on the main shaft 2. The spool 8 is connected to the gear shifting cable.
[0044] The torsion spring 16 is installed between the spool 8 and the main shaft 2. The teeth on the gear tooth 7 abut against the anti-reset assembly in the clockwise direction of the main shaft 2 and engage with the self-reset claw in the clockwise direction of the main shaft 2.
[0045] The gear shifter 7 rotates synchronously with the spool 8. Both shifting up and down are achieved by the synchronous rotation of the gear shifter 7 and spool 8, which pulls the shift cable, enabling the chain to mesh with different gears on the front and rear sprockets. In the initial state, i.e., the lowest gear, the spool torsion spring 16 is in a free state. Even if a shift is accidentally reversed, the gear shifter 7 will not rotate due to the spool torsion spring 16. When shifting down from a higher gear, the gear shifter 7 rotates clockwise due to the torque of the spool torsion spring 16. When shifting up, the self-resetting pawl contacts and engages the gear shifter 7, causing it to rotate counterclockwise. Simultaneously, the anti-resetting component prevents shifting down, thus enabling the shifting operation.
[0046] The solution has been further optimized, and the self-resetting anti-backlash component includes:
[0047] Anti-reverse pawl 6 is rotatably connected to main seat 1;
[0048] The anti-reverse pawl torsion spring 15 is installed at the rotatable connection between the anti-reverse pawl 6 and the main seat 1. The anti-reverse pawl 6 and the gear tooth 7 are abutted in the clockwise direction of the main shaft 2.
[0049] In the initial state, i.e. the lowest gear, the anti-reverse pawl 6 is engaged with the gear tooth 7 under the action of the anti-reverse pawl torsion spring 15.
[0050] Further optimization of the design includes: Anti-reverse claw 6 includes:
[0051] The first claw 601, the second claw 602, and the third claw 603 are fixedly connected and distributed circumferentially. The third claw 603 is located in a clockwise direction close to the main shaft 2, and the first claw 601 is located in a counterclockwise direction close to the main shaft 2. By rotating the reset handle lever 9 clockwise, the second claw 602 is pushed and the gear tooth 7 is released clockwise.
[0052] Further optimizations include the following for the gear torque component:
[0053] The protrusion 301 is fixedly connected to the side of the advance / retractor 3 and is located near the second claw 602. The protrusion 301 is in a counterclockwise direction relative to the second claw 602 and closer to the spindle 2.
[0054] Further optimizations to the plan include:
[0055] The lever 901 is fixedly connected to the side of the handle lever 9 and is axially inserted into the side of the advance / retract seat 3.
[0056] Further optimization of the design includes the following self-resetting claw:
[0057] The pawl 4 is rotatably connected to the side of the forward / reverse seat 3 and engages with the clockwise side of the teeth on the gear shift 7.
[0058] The pawl torsion spring 5 is installed at the rotatable connection between the pawl 4 and the forward / reverse seat 3.
[0059] On gear shifter 7, the teeth closer to the counter-clockwise direction are the low gear teeth, and the teeth closer to the clockwise direction are the high gear teeth; for example... Figure 5 In the initial state, i.e., the lowest gear, the pawl 4 engages with the clockwise side of the teeth on the gear shift 7. When shifting gears, the lever 9 is turned counterclockwise, causing the shift block 901 to move the shift / reverse seat 3 counterclockwise. The pawl 4 pushes the gear shift 7 to rotate counterclockwise, and the torsion spring 16 generates a restoring force. When the lever 9 rotates counterclockwise to the designated position and can no longer rotate, the gear shift 7 rotates by the angle corresponding to one gear. During this process, the higher gear teeth on the gear shift 7 push the first pawl 601, causing the anti-reverse pawl 6 to rotate. When the gear shifter moves at a certain angle, the anti-reverse pawl torsion spring 15 generates a restoring force. When the higher gear tooth on the gear shifter 7 passes the first pawl 601, the anti-reverse pawl 6 returns to its original position under the restoring force of the anti-reverse pawl torsion spring 15. When the lever 9 is released, the forward / reverse seat 3 drives the lever 9 to rotate coaxially and return to its original position under the action of the forward / reverse seat torsion spring 3. Under the restoring force of the pulley torsion spring 16, the gear shifter 7 rotates clockwise. Just as it passes the higher gear tooth on the first pawl 601, it is blocked by the first pawl 601, and the gear shifter 7 cannot continue to rotate clockwise. At this point, one gear shift is completed. During the gear shifting process, the forward pawl 4 is always engaged with the clockwise side of the teeth on the gear shifter 7.
[0060] When downshifting from a high gear, turn the lever 9 clockwise to move the shifting seat 3 and the pawl 4 until the protrusion 301 contacts and pushes the second pawl 602. The stop pawl 6 begins to rotate clockwise, and the side wall of the first pawl 601 contacts the pawl 4 and pushes the pawl 4 to rotate counterclockwise. The first pawl 601 gradually disengages from the gear shift gear 7, and the stop pawl torsion spring 15 generates a rebound force, causing the pawl 4 to gradually disengage from the gear shift gear 7. When the first pawl 601 is completely disengaged from the current gear tooth of the gear shift gear 7 and the pawl 4 is completely disengaged from the gear shift gear 7, the gear shift ends. The gear 7 rotates clockwise under the restoring force of the pulley torsion spring 16. The higher gear tooth on the gear 7, which is close to the current gear tooth, is blocked by the third pawl 603. When the lever 9 is released, the shift seat 3 rotates counterclockwise under the restoring force of the shift seat torsion spring. The protrusion 301 disengages from the second pawl 602, the anti-reverse pawl 6 resets, and the lower gear tooth on the gear 7, which is close to the current gear tooth, is blocked by the first pawl 601. The forward pawl 4 re-engages on the gear 7 under the restoring force of the anti-reverse pawl torsion spring 15, thus completing one downshift.
[0061] Further optimizations to the plan include:
[0062] Pull plate 13, the first end of pull plate 13 is fixedly sleeved on spindle 2, and the second end of pull plate 13 is sleeved at the rotation center of anti-reverse pawl 6 and main seat 1.
[0063] The main function of the pull plate 13 is to prevent the handle lever 9 from sliding out from the top of the spindle 2, and it can also be used to fix the anti-reverse claw torsion spring 15.
[0064] Further optimizations to the plan include:
[0065] Spiral groove 801 is formed on the roller 8;
[0066] The slide column 1001 is axially fixed to the end of the pointer 10 and extends axially into the spiral groove 801.
[0067] The centripetal end of the spiral groove 801 is close to the center of the spool 8 along the spiral direction; when the spool 8 and the gear tooth 7 rotate synchronously, the spiral groove 801 pushes the slide column 1001, thereby pushing the pointer 10 to rotate a certain angle, and the gear shifting or reversing status can be observed through the pointer 10.
[0068] Further optimizations to the plan include:
[0069] A transparent plate 11 is mounted on the upper cover 12 and is set to correspond with the pointer 10.
[0070] The transparent plate 11 makes it easy to observe the pointer 10.
[0071] Further optimizations to the plan include:
[0072] Bushing 14 is fitted on main shaft 2. Thread pulley 8, gear plate 7 and advance / retract seat 3 are fitted on bushing 14 from top to bottom.
