Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a multifunctional operating device for controlling a bicycle transmission or a lifting seat tube. Background Art

[0002] Existing road bicycles are usually provided with a brake and speed change operating device for controlling the brake device and the transmission to achieve the braking and gear shifting operations of the bicycle. The brake and speed change operating device is arranged on the handlebar, and most brake and speed change operating devices are controlled by metal wires, which connect the brake and speed change operating device to the brake device for braking, and to the transmission for gear shifting.

[0003] In order to make road bicycles more versatile, the height of the seat cushion can be adjusted by using a dropper seat tube of the bicycle. In the prior art, when the dropper seat tube of a bicycle needs to be adjusted, the bicycle usually needs to be stopped, and the dropper seat tube needs to be adjusted again after getting off the bicycle, so as to adjust the bicycle seat cushion to a suitable height. On roads with many ups and downs, the height of the seat cushion needs to be adjusted repeatedly during riding, and the traditional adjustment method is very inconvenient.

[0004] In order to facilitate the adjustment of the dropper, an additional operating device needs to be provided on the handlebars for operation, which increases the production cost. In addition, the existing operating device does not have the function of fine-tuning the travel of the dropper, and the metal wires of road bicycles are mainly arranged in an inner line. If the metal wires of the dropper are arranged in an inner line, the function of fine-tuning the travel needs to be solved by the design of other components, otherwise the adjustment is very inconvenient. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned problems and provide a multifunctional operating device for controlling a bicycle transmission or a lifting seat tube. The multifunctional operating device is a universal device that can realize braking and speed change operations, or realize braking and lifting and lowering adjustment of the lifting seat tube. The functions are replaced by speed change operations and lifting and lowering of the lifting seat tube. There is no need to set up an additional operating device to operate the lifting seat tube, which saves production costs. The multifunctional operating device can realize speed change operations, has a gear function, and can realize the function of fine-tuning the stroke of the lifting seat tube, thereby improving convenience in use.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A multifunctional operating device for controlling a bicycle transmission or a lifting seat tube, comprising a bracket body, a brake shaft, a brake / operating lever assembly and an operating unit; the brake / operating lever assembly is hinged on the bracket body through the brake shaft, and the operating unit is arranged on the brake / operating lever assembly; wherein, when the operating unit is used to implement a speed change operation, the operating unit is connected to the transmission through a metal wire; when the operating unit is used to implement a lifting operation of a lifting seat tube, the operating unit is connected to the lifting seat tube through a metal wire.

[0008] The working principle of the above multifunctional operating device for controlling a bicycle transmission or a dropper seat tube is as follows:

[0009] When braking, hold the brake / operating lever assembly, and the brake / operating lever assembly rotates around the axis of the brake shaft. During the rotation, since the operating unit is arranged on the brake / operating lever assembly, the operating unit also moves with the brake / operating lever assembly; when changing speed, turn the brake / operating lever assembly, the brake / operating lever assembly controls the operating unit to adjust the metal wire to move, and the metal wire triggers the transmission to change speed and shift gears; when adjusting the dropper, turn the brake / operating lever assembly, the brake / operating lever assembly controls the operating unit to adjust the metal wire to move, and the metal wire triggers the dropper to achieve the lifting and lowering adjustment of the dropper, and the adjustment stroke is designed to match the lifting switch stroke of the dropper; the multifunctional operating device can achieve the speed change operation, which means that the multifunctional operating device has multiple gears, and therefore, the gear adjustment can be achieved for the dropper, thereby achieving the function of fine-tuning the stroke of the dropper; specifically, when fine-tuning the initial position of the lift switch of the dropper, turn the brake / operating lever assembly, and adjust the initial idle stroke of the lift switch of the dropper through the set mechanical positioning (different gears).

[0010] A preferred solution of the utility model, wherein the operating unit has more than two gears, the brake / operating lever assembly has an operating stroke, the operating stroke includes a fine-tuning stroke and a working stroke; the lifting seat tube has a switch stroke, the switch stroke includes an idle stroke and a trigger stroke; when the operating unit is used to realize the lifting operation of the lifting seat tube, the gear is used to adjust the idle stroke and the fine-tuning stroke of the lifting operation. In the above structure, the fine-tuning stroke corresponds to the idle stroke, and the working stroke corresponds to the trigger stroke. When the brake / operating lever assembly is turned to shift gears, the fine-tuning stroke changes, and the distance of the corresponding idle stroke also changes. When the brake / operating lever assembly is turned to enter the working stroke, the lifting seat tube also enters the trigger stroke, the lifting switch of the lifting seat tube begins to be triggered, and the lifting of the lifting seat tube can be adjusted; the idle stroke is the stroke before the lifting switch of the lifting seat tube is triggered; the trigger stroke is the stroke for triggering the lifting switch of the lifting seat tube. When the operating unit is used to realize the lifting and lowering operation of the dropper, the brake / operating lever assembly is toggled to realize the gear adjustment, that is, the distance adjustment of the fine-tuning stroke, and the operating stroke is the stroke of the brake / operating lever assembly until the lifting switch of the dropper is triggered; specifically, after all gears are crossed, the working stroke, that is, the triggering stroke, is entered, and the dropper starts to be triggered; the role of the gear is: the brake / operating lever assembly is manually toggled, and after the gear is shifted, its fine-tuning stroke can be reduced, that is, the larger the gear toggled, the shorter the distance to enter the working stroke, and then the shorter the stroke to trigger the dropper, that is, the shorter the idle stroke, and the user can select it according to the size of the hand to reduce the operating stroke; in addition, different gears can be selected on different road surfaces. When the operating unit has two gears, for example, the second gear can be selected on a flat road surface, which has a more sensitive operation, and only a small range needs to be toggled to trigger the dropper; on a bumpy road surface, the first gear can be selected to reduce operating errors, and a larger range needs to be toggled to trigger the dropper.

[0011] Preferably, the working stroke is a stroke greater than or equal to 3.6 mm. When the operating unit passes through all gears, it begins to enter the working stroke, and at the same time, the dropper tube also enters the triggering stroke. When the brake / operating lever assembly is moved, when the gear is shifted to the last gear, the brake / operating lever assembly is continued to be moved to enter the working stroke. After entering the working stroke, the lifting function of the dropper tube is triggered.

[0012] Preferably, the brake / operating lever assembly includes a base arranged on the brake shaft, a brake / operating lever rotatably arranged on the base, and a release lever, the operating unit is rotatably arranged on the base, and the brake / operating lever and the release lever are used to control the operating unit. In the above structure, by turning the brake / operating lever and the release lever together on the base, the operating unit can be operated to achieve the winding of the metal wire, thereby achieving the gear adjustment of the transmission or the dropper, when the release lever is turned alone in the same direction, the operating unit can be operated to achieve the release of the metal wire, thereby achieving the gear adjustment of the transmission or the dropper; when the brake / operating lever is operated to rotate around the brake shaft, the brake of the bicycle can be achieved; when braking, the brake / operating lever moves together with the base.

[0013] Preferably, a fixing device for fixing the brake / operating lever and the release lever is provided between the brake / operating lever and the release lever; the fixing device is a screw, and the screw is used to fix the release lever on the brake / operating lever. The purpose is that when the operating unit is used to realize the lifting and lowering operation of the lifting seat tube, after selecting the gear position, the brake / operating lever and the release lever are fixed by the screw, and can be fixed or not fixed. When not fixed, the screw can be removed. When fixed, the brake / operating lever and the release lever form a whole, realizing single-lever operation and reducing erroneous operation. If not fixed, the gear position can be switched, and the operator can put it at the maximum angle to reduce the travel and reduce erroneous operation on bumpy roads.

[0014] Preferably, the brake / operating rod is provided with a threaded hole, the release rod is provided with a mounting hole, and the screw passes through the mounting hole and is matched with the threaded hole. The threaded hole and the mounting hole are provided to facilitate the installation and alignment of the screw.

[0015] Preferably, the operating unit includes a shift shaft fixedly arranged on a base, a C-shaped member movably arranged on the base, and a retaining ratchet rotatably arranged on the shift shaft; the brake / operating lever takes the shift shaft as the rotation center, the C-shaped member is provided with a first positioning tooth, and the retaining ratchet is provided with at least two second positioning teeth, and the first positioning tooth is used to position the second positioning tooth to achieve the positioning of the gear position. By setting the above structure, the first positioning tooth on the C-shaped member is used for gear position retention, and the number of the second positioning teeth corresponds to the number of gear positions, so as to achieve the gear position adjustment of the transmission or the lifting seat tube; the brake / operating lever and the release lever are moved together to drive the retaining ratchet to rotate, and the second positioning tooth on the retaining ratchet can pass over the first positioning tooth, and the first positioning tooth positions the next second positioning tooth to complete a gear shift; when the release lever is moved alone, the C-shaped member is pushed to move, and the first positioning tooth is separated from the second positioning tooth. Under the action of the elastic force, the retaining ratchet rotates in the opposite direction to complete a gear shift.

[0016] Preferably, when the dropper is adjusted to be raised or lowered, after all the second positioning teeth pass over the first positioning teeth, the ratchet is kept to have the working stroke. The brake / operating lever and the release lever are moved together, and after all the second positioning teeth pass over the first positioning teeth, the brake / operating lever and the release lever are continued to be moved, the ratchet is kept to rotate along the working stroke, and the metal wire continues to wind and move, which triggers the dropper to be adjusted to be raised or lowered.

[0017] Preferably, the bracket body is mounted on the handlebar, and a channel is provided on the bracket body, and the metal wire coming out of the operating unit passes through the channel and then runs along the handlebar. The purpose is to prevent the metal wire from being exposed outside the multifunctional operating device, making the wiring of the metal wire more concealed and improving safety.

[0018] Preferably, the brake shaft is provided with a through hole, and the metal wire coming out of the operating unit passes through the through hole and then extends out of the channel. The through hole is provided to facilitate the routing of the metal wire. When braking, the brake / operating lever assembly rotates around the axis of the brake shaft. During the rotation, the operating unit also moves with the brake / operating lever assembly. During the braking process, the displacement of the metal wire will not affect the operation of the operating unit, preventing the operating unit from accidentally pulling the metal wire to trigger the gear shifting or the lifting and lowering operation of the seat tube during braking.

[0019] Furthermore, the axis of the through hole is perpendicular to the axis of the brake shaft. The purpose is that the through hole can play a good guiding role for the metal wire, ensuring that the metal wire is more stably routed inside.

[0020] Preferably, the transmission is a bicycle front transmission, because the bicycle front transmission has fewer gears and is more compatible with controlling the dropper seat tube.

[0021] Preferably, the brake / operating lever assembly rotates at an angle of 0-50° with the brake shaft as the center. The purpose is that when braking, the brake / operating lever assembly rotates at 0-50° with the brake shaft as the center, and extends to the outside of the bracket body through the bracket body; this process moves back and forth continuously, and due to the effect of the through hole, the displacement of the metal wire during the process does not affect the operating unit.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. The multifunctional operating device of the utility model, when changing speed, moves the brake / operating lever assembly, the brake / operating lever assembly controls the operating unit to adjust the metal wire to move, and the metal wire triggers the transmission to change speed and shift gears; when adjusting the dropper tube, moves the brake / operating lever assembly, the brake / operating lever assembly controls the operating unit to adjust the metal wire to move, and the metal wire triggers the dropper tube to achieve the lifting and lowering adjustment of the dropper tube; by replacing the functions of the speed change operation and the lifting and lowering of the dropper tube, there is no need to set up an additional operating device to operate the dropper tube, thereby saving production costs.

[0024] 2. The multifunctional operating device of the utility model can be used as a speed-changing operating device and can also be used as a seat tube lifting and lowering operating device. The multifunctional operating device has strong versatility.

[0025] 3. The multifunctional operating device of the utility model can realize the speed change operation, which means that the multifunctional operating device has a gear function. Therefore, the gear adjustment of the dropper tube can be realized, thereby realizing the function of fine adjustment of the stroke of the dropper tube. Moreover, the function of fine adjustment of the stroke does not require the cooperation of other components in the design and solution, and can be achieved by toggling the brake / operating lever assembly, which is very convenient to adjust and improves the convenience of use.

[0039] See also Figure 5-Figure 8 The bracket body 1 is mounted on the handlebar, and a channel 9 is provided on the bracket body 1. The metal wire 7 coming out of the operating unit 4 passes through the channel 9 and then runs along the handlebar. The purpose is to prevent the metal wire 7 from being exposed outside the multifunctional operating device, so that the wiring of the metal wire 7 is more concealed and the safety is improved.

[0040] See also Figure 1-Figure 2 and Figure 5-Figure 8 The brake shaft 2 is provided with a through hole 8, and the metal wire 7 coming out of the operating unit 4 passes through the through hole 8 and then extends out of the channel 9. The through hole 8 is provided to facilitate the routing of the metal wire 7. When braking, the brake / operating lever assembly 3 rotates around the axis of the brake shaft 2. During the rotation, the operating unit 4 also moves with the brake / operating lever assembly 3. During the braking process, the displacement of the metal wire 7 will not affect the operation of the operating unit 4, preventing the operating unit 4 from accidentally pulling the metal wire 7 to trigger the shifting or lifting and lowering operation of the seat tube 6 during braking.

[0041] See also Figure 5-Figure 8The axis of the through hole 8 is perpendicular to the axis of the brake shaft 2. The purpose is that the through hole 8 can play a good guiding role for the metal wire 7, ensuring that the metal wire 7 is more stable when it is routed inside.

[0042] See also Figure 1 The transmission 5 is a bicycle front transmission. Since the front transmission of a bicycle has fewer gears, it is more compatible with controlling the lifting seat tube 6.

In the above structure, the fine-tuning stroke corresponds to the idle stroke, and the working stroke corresponds to the trigger stroke. When the brake / operating lever assembly 3 is turned to shift gears, the fine-tuning stroke changes, and the distance of the corresponding idle stroke also changes.

When the operating unit 4 has two gears, for example, the gear 2 can be selected on a flat road surface, which has a more sensitive operation, and only a small range needs to be toggled to trigger the lifting seat tube 6; on a bumpy road surface, the gear 1 can be selected to reduce operating errors, and a larger range needs to be toggled to trigger the lifting seat tube 6.
