Description

Shift control box and bicycle control components

The invention relates to a control box and a control assembly, in particular to a speed change control box and a bicycle control assembly.

In the past, the transmission of the bicycle was a mechanical transmission. The rider needed to operate the mechanical transmission handle to drive the cable to drive the mechanical transmission. Or you need to apply more force to operate the mechanical shifting handle to make the derailleur move the chain to the chainring.

At present, bicycle manufacturers have developed electronic transmissions and electronic transmission handles. The electronic transmissions are equipped with electronic components such as motors and control circuit boards. There are switches in the electronic transmission handles. After the switches are triggered, they are transmitted through the signal. Operate the motor of the electronic derailleur to move the chain to the target chainring. Since the actuation of the electronic shifter requires only a force that triggers the switch in the electronic shifter handle, this method is less labor-intensive than the method of operating the mechanical shifter handle to drive the cable to drive the mechanical shifter. In addition, the electronic transmission moves the chain electrically, so compared with the method of driving the chain through a cable-driven mechanical transmission, the electronic transmission moves the chain more smoothly.

However, the current electronic shifting architecture requires the use of an electronic shifter and an electronic shifting handle at the same time. Therefore, if you want to upgrade the mechanical shifting to an electronic shifting handle and upgrade the mechanical shifting handle to an electronic shifting handle at the same time, the cost will be relatively high. And reduced the willingness of the user to upgrade the rear transmission. Therefore, researchers in this field are currently working on solving the aforementioned problems.

The present invention provides a speed change control box and a bicycle control assembly, which can make a mechanical speed change handle and an electronic speed changer work together.

A bicycle control assembly disclosed in an embodiment of the present invention includes a shift lever, a cable, a shift control box and an electronic transmission. The shifting lever is connected to the shifting control box through a cable. The variable speed control box includes a signal triggering device. The electronic transmission signal is connected to the signal triggering device of the transmission control box. The shift lever is used to be operated, and the signal trigger device is triggered through the cable to transmit a signal to the electronic shifter.

Another embodiment of the present invention discloses a speed change control box, which is used to connect a cable and control a bicycle electronic device. The speed change control box includes a casing, a traction member and a signal triggering device. The casing has an accommodating space, and the casing is used for cables to pass through, so that different parts of the cables are respectively located inside and outside the accommodating space. The traction member is located in the accommodating space and is used for pulling the cable to provide a force for the cable to move from the outside of the accommodating space to the direction of the accommodating space. The signal trigger device is located in the accommodation space and is used for signal connection with the electronic device of the bicycle. The signal triggering device is used to send a signal to the electronic device of the bicycle by being triggered by the pulled cable.

According to the transmission control box and the bicycle control assembly disclosed in the above embodiments, the transmission control box is connected with the cable, and the transmission control box includes a signal trigger device for connecting the signal to the electronic device of the bicycle, and a cable for the signal trigger device to be moved. The configuration that the cable triggers and transmits a signal to the bicycle electronic device enables the bicycle mechanical device that pulls the cable to control the bicycle electronic device through the shift control box. In this way, the shifter can be used with the electronic shifter in the case where the mechanical device of the bicycle is a shifter and the electronic device of the bicycle is an electronic shifter. Therefore, when the user wants to use an electronic rear derailleur, he only needs to upgrade the mechanical derailleur to an electronic derailleur and then match it with a transmission control box instead of upgrading the mechanical derailleur to an electronic derailleur. Enjoy the smoothness of electronic transmission and derailleur with less cost.

The upper cover 312 is fixed to the base 311 through screws, for example. The upper cover 312 has an opening 3121 , and the opening 3121 is aligned with the guiding groove 31141 . The transmission control box 30 can also include a see-through window 34, which is made of light-transmitting material. The see-through window 34 is installed in the opening 3121 of the upper cover 312, so that the rider can see the cable 20 in the guide groove 31141 from the outside of the shift control box 30, and its purpose will be explained later.

In this embodiment, the traction member 32 includes a tension spring 321 . Two opposite ends of the extension spring 321 are respectively fixed to the housing 31 and one end of the cable 20 . In detail, the traction member 32 may further include an assembly part 322 and a tension adjusting part 323 .

The tension adjusting member 323 is disposed on the base 311 in an adjustable position. The tension spring 321 is located in the guide groove 31141 of the guide structure 3114, and one end of the tension spring 321 is fixed to the end 21 of the cable 20 through the assembly part 322, and the other end of the tension spring 321 is through the tension adjustment part 323 It is fixed on the base 311 so that the tension spring 321 is located between the cable 20 and the tension adjusting member 323 .

Furthermore, the base 311 can also have two stop structures 3116 . The stop structure 3116 is connected to the guide structure 3114 and located on two opposite sides of the guide groove 31141 . The assembly part 322 has two lugs 3221 , and the two lugs 3221 of the assembly part 322 abut against the side of the two stopper structures 3116 facing away from the tension adjustment part 323 respectively. In addition, the base 311 can also have an assembly groove 3117 communicating with the guiding groove 31141 . The assembly groove 3117 has a plurality of fixing portions 31171 , and the distances between these fixing portions 31171 and the stop structure 3116 are different. The tension adjusting member 323 is selectively fixed to one of the fixing portions 31171 of the assembling groove 3117 . Referring to FIG. 2 , the tension adjusting member 323 is disposed on the fixing portion 31171 in the middle of the fixing portions 31171 .

The tension spring 321 provides a force for the cable 20 to move from the outside of the accommodating space 3111 to the direction of the accommodating space 3111 through the assembly part 322 . The two stop structures 3116 are used to limit the movement of the cable 20 along the force direction provided by the tension spring 321 . When the shift lever 11 is not operated and the cable 20 is not pulled, the assembly 322 remains against the stop structure 3116 due to the elastic force of the tension spring 321, so that the assembly 322 and the cable 20 The end portion 21 is positioned at an initial position and cannot move in the direction of the force provided by the tension spring 321 .

Therefore, when the tension adjusting member 323 is fixed on the fixing portion 31171 farthest from the stop structure 3116, the force required to pull the cable 20 is greater than when the tension adjusting member 323 is fixed on the fixing portion 31171 closest to the stop structure 3116. 20, and the force required to pull the cable 20 when the tension adjusting member 323 is disposed on the fixing portion 31171 in the middle of the fixing portions 31171 is between the aforementioned two. Therefore, the user can adjust the position of the tension adjusting member 323 between these fixing parts 31171 according to the preferred feel.

It should be noted that the tension adjusting member 323 is an optional component. In other embodiments, the traction member may not have a tension adjusting member, and the base may omit the structure of the assembly groove, and one end of the tension spring may be directly fixed to the base.

On the other hand, the stop structure 3116 is an optional structure. In other embodiments, the base may have no stop structure. In such an arrangement, the position of the end of the cable is the initial position when the tension spring is not stretched.

Furthermore, the assembly part 322 is an optional component. In other embodiments, the traction member may have no assembly, and one end of the tension spring may be fixed directly to one end of the cable.

In addition, the traction member 32 is not limited to include the tension spring 321 . In other embodiments, the traction member may include other elements suitable for providing force for the cable to move from outside the accommodating space to inside the accommodating space.

The signal triggering device 33 includes a circuit board 331 , a sensor 332 and a triggering element 333 . The circuit board 331 is located in the accommodating space 3111 of the base 311 and is farther away from the opening 3112 than the guiding structure 3114 .

In detail, the sensor 332 is, for example, a Hall sensor, and the trigger 333 is, for example, a magnet. The trigger part 333 is disposed on one end of the cable 20 through the assembly part 322 . In another embodiment where the traction member has no assembly, the trigger can be placed directly on one end of the cable.

The electronic derailleur 40 is, for example, an electronic rear derailleur, which is connected to the circuit board 331 for signals. In detail, the circuit board 331 has a control unit 3311 , an antenna unit 3312 and a storage unit 3313 , and the antenna unit 3312 and the storage unit 3313 are electrically connected to the control unit 3311 . The antenna unit 3312 of the circuit board 331 is connected to the electronic transmission 40 in a wireless manner.

In this embodiment, through the configuration of the guide groove 31141 of the guide structure 3114 of the base 311, the cable 20 can drive the assembly part 322 and The trigger member 333 moves linearly relative to the sensor 332 . Of course, the guiding structure 3114 is an optional structural configuration. In other embodiments, the base may omit the guiding structure.

When the cable 20 is pulled to drive the trigger 333 to move, the sensor 332 senses different potential differences due to the change of the magnetic density as the trigger 333 moves at different distances, so a comparison table can be prepared in advance and stored together The comparison table summarizes the potential differences sensed by the sensor 332 when the trigger member 333 is at different distances from its initial position, and these potential differences correspond to multiple gear positions of the electronic transmission 40 respectively. In this way, the movement of the trigger 333 can be sensed when the cable 20 is pulled by the potential difference sensed by the sensor 332 , and the desired gear position of the electronic transmission 40 can be obtained indirectly.

For example, as shown in FIGS. 3 and 4 , when the electronic transmission 40 (as shown in FIG. 1 ) is in the lowest gear (the first gear), the assembly part 322 is relatively far away from the threading hole corresponding to the perspective window 34 One end 341 of 3115 , and the trigger 333 is located right above the sensor 332 .

At this time, the potential difference sensed by the sensor 332 changes as the distance between the trigger 333 and the sensor 332 changes, and the control unit 3311 of the circuit board 331 will store the current potential difference sensed by the sensor 332 The gear corresponding to the potential difference recorded in the comparison table in the unit 3313 makes the antenna unit 3312 send a shift signal to the electronic transmission 40, so that the electronic transmission 40 shifts from the first gear to the gear.

Conversely, when the user intends to reverse the electronic transmission 40, the cable 20 can be loosened by operating the reverse shift lever 12, so that the tension spring 321 rebounds and drives the assembly to move towards the end 341 of the see-through window 34, In order to pull the cable 20 into the accommodating space 3111 of the base 311 and shorten the distance between the trigger 333 and the sensor 332 . At this time, the control unit 3311 of the circuit board 331 will make the antenna unit 3312 send a shift signal to The electronic transmission 40, and the electronic transmission 40 is shifted back to the gear.

In this embodiment, the variable speed control box 30 is connected to the cable 20, and the variable speed control box 30 includes a signal trigger device 33 that is connected to the electronic transmission 40, and the signal trigger device 33 can be triggered by the moving cable 20. The configuration of transmitting the signal to the electronic transmission 40 enables the shift dial 10 pulling the cable 20 to control the electronic transmission 40 through the transmission control box 30 . That is to say, the mechanical shift lever 10 can be used in conjunction with the electronic shifter 40 through the shift control box 30 . In this way, when the user wants to use the electronic transmission 40, he only needs to upgrade the mechanical transmission to the electronic transmission 40 and then match the transmission control box 30, instead of upgrading the mechanical transmission dial 10 to an electronic transmission. Shifting the handle, that is, you can enjoy the smoothness of the electronic transmission 40 and the shifting chain at a relatively small cost.

On the other hand, since the variable speed control box 30 and the variable speed dial 10 are connected through the cable 20, the variable speed control box 30 is suitable for the variable speed dials of multiple brands that can drive the cable 20 on the market. The restrictions on the use of the transmission control box 30 are reduced.

Next, as shown in FIG. 8 and FIG. 10 , the bicycle control assembly 1a may further include a second shifting handle 50a, a second cable 60a and a second electronic transmission 70a.

The second shift dial 50a is connected to the shift control box 30a through the second cable 60a, and the second shift dial 50a controls the second electronic transmission 70a through the shift control box 30a. For example, the second shift dial 50a is a mechanical shift dial, and the second electronic transmission 70a is an electronic rear derailleur.

The second cable 60a can be released by operating the reverse gear lever 52a, and the second electronic transmission 70a can be reversed through the transmission control box 30a. The details will be described below.

In this embodiment, the base 311a may further have a second threading hole 3115a communicating with the accommodating space 3111a. The second cable 60a passes through the base 311a through the second threading hole 3115a, and has different parts respectively located inside and outside the accommodating space 3111a. The transmission control box 30a can further include a second traction member 36a, and the second traction member 36a is located in the accommodating space 3111a of the base 311a. The second traction member 36a includes a torsion spring 361a and a winding wheel 362a. The cord reel 362a is rotatably disposed on the base 311a, and two opposite ends of the torsion spring 361a are respectively fixed to the base 311a and the cord reel 362a. One end of the second cable 60a is fixed to the winding wheel 362a, and the second cable 60a is wound on the winding wheel 362a. The torsion spring 361a provides force for the second cable 60a to move from the outside of the accommodating space 3111a to the direction of the accommodating space 3111a through the reel 362a.

The signal triggering device 33a may further include a sensor 333a and a triggering element 334a. The sensor 333a is, for example, a Hall element. The sensor 333a is disposed on the circuit board 331a and electrically connected to the control unit 3311a of the circuit board 331a. The trigger 334a is, for example, a magnet, and the trigger 334a is disposed on the reel 362a and corresponds to the sensor 333a.

In this embodiment, by operating the shift lever 51a of the second shifting knob 50a, the second cable 60a can drive the winding wheel 362a and the trigger member 334a on it to rotate relative to the sensor 333a. When the second cable 60a is pulled to drive the trigger 334a to rotate, with the different rotation angles of the trigger 334a, the sensor 333a senses different potential differences due to the change of the magnetic density, so a comparison table can be prepared in advance And stored in a storage unit 3313a electrically connected to the control unit 3311a of the circuit board 331a, this comparison table summarizes the potential difference sensed by the sensor 333a when the trigger 334a is at different angles from its initial position, and these potential differences are respectively It also corresponds to a plurality of gear positions of the second electronic transmission 70a. In this way, with the potential difference sensed by the sensor 333a, the rotation of the trigger 334a can be sensed when the second cable 60a is pulled, and the desired gear position of the second electronic transmission 70a can be obtained indirectly. .

Next, please refer to FIGS. 7 , 8 and 12 . FIG. 12 is a schematic top view of the cable shown in FIG. 10 being pulled. When the user wants to shift the second electronic transmission 70a into gear, he can pull the second cable 60a by operating the shift lever 51a of the second shift dial 50a, so that the second cable 60a drives the winding wheel 362a and triggers the second cable 60a. Member 334a rotates. At this time, the potential difference sensed by the sensor 333a changes as the angle of the trigger 334a relative to the sensor 333a changes, and the control unit 3311a of the circuit board 331a will detect the current potential difference and the storage unit according to the current potential difference sensed by the sensor 333a. The gear position corresponding to the potential difference recorded in the comparison table in 3313a makes the antenna unit 3312a send a shift signal to the second electronic transmission 70a to shift the second electronic transmission 70a to the gear position.

Conversely, when the user intends to reverse the second electronic transmission 70a, the second cable 60a can be loosened by operating the reverse shift lever 52a of the second shifting handle 50a, so that the torsion spring 361a drives the winding wheel 362a and triggers The member 334a rotates and winds the second cable 60a.

However, the number of gears of the first electronic transmission 40a is not intended to limit the present invention. In other embodiments, the number of gears of the first electronic transmission 40a may be greater than two. Under such a configuration, a combination of a Hall sensor and a magnet can be used instead to sense the pulling or loosening of the first cable, so as to control the first electronic transmission to change these gears.

In addition, since the second electronic transmission 70a has a large number of gear positions, the space required for the combination of the Hall sensor and the magnet that can rotate with the winding wheel 362a can be compared with that of the Hall sensor and the linear type. The collocation of the moving magnet requires little space, and the volume of the variable speed control box 30a can be reduced as much as possible.
