Abstract
The utility model discloses a kind of speed-change control device on bicycle, including the selector button, MCU and stepper motor being electrically connected with successively, and the cable quadrant being connected with stepper motor output shaft, cable quadrant connects speed changer, the button sends gear-shift command to MCU, MCU control stepper motors rotate, and then pull the shift cable of cable quadrant to realize speed change.Speed-change control device provided by the utility model on bicycle, can use common speed changer, and the installation of ordinary bicycle can greatly reduces the threshold using electronic transmission.Speed-change control device provided by the utility model on bicycle, the scheme used is more economical, greatly reduces cost.The utility model may be mounted at ordinary bicycle and above common electric bicycle, using conventional transmission device can on bicycle, easy for installation, cost is also seldom.
Description
Technical field
It the utility model is related to bicycle art, more particularly to a kind of speed-change control device on bicycle.
Background technology
At present, the speed changer of bicycle has two kinds, it is a kind of be electronic transmission it is a kind of be common mechanical transmission, machinery
It is not very convenient that the speed changer of formula needs to use hand to dial, and the electronic transmission of electronic transmission easily still in the market is all
Your unusual maintenance cost is also very high common and its is fragile, and the present invention just therebetween, directly may be used by ordinary bicycle
With repacking, using the mechanical transmission of routine, as long as easy for installation look for a fixed position, ordinary person on bicycle
Can installation and debugging, cost are also cheaply more many than electronic transmission currently on the market.
Utility model content
The present invention seeks to：In view of the above-mentioned problems, the utility model provides a kind of speed Control dress on bicycle
Put, substantially reduce the cost of electronic transmission, improve the convenience of installation.
The technical solution of the utility model is：
A kind of speed-change control device on bicycle, including selector button, MCU and the stepping electricity being electrically connected with successively
Machine, and the cable quadrant being connected with stepper motor output shaft, cable quadrant connection speed changer, the button send speed change to MCU and referred to
Order, MCU control stepper motors rotate, and then pull the shift cable of cable quadrant to realize speed change.
Preferably, the selector button includes the button state of different stalls, and MCU is according to the different button-likes received
State, judge transforming gear amplitude.
Preferably, after the MCU instructs according to selector button gear, control stepper motor rotates the corresponding angle of the gear
Degree.
Preferably, the stepper motor pulls shift cable to shrink or loosen corresponding length after rotating certain angle, real
The speed change of existing different stalls.
The utility model has the advantages that：
1. the speed-change control device provided by the utility model on bicycle, common speed changer can be used,
The installation of ordinary bicycle can greatly reduces the threshold using electronic transmission.
2. the speed-change control device provided by the utility model on bicycle, the scheme used is more economical, significantly
Reduce cost.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1 is the theory diagram of the speed-change control device described in the utility model on bicycle
Fig. 2 is the workflow diagram of the utility model speed-change control device；
Fig. 3 is scheme of installation of the utility model speed-change control device on bicycle.
Embodiment
As shown in figure 1, the speed-change control device being used on bicycle disclosed in the utility model, including electrically connect successively
Selector button, MCU and the stepper motor connect, and the shift cable being connected with stepper motor output shaft, in addition to be above-mentioned each portion
Part provides the power supply of operating voltage, and the button sends gear-shift command to MCU, and MCU control stepper motors rotate, and then pull and become
Fast line realizes speed change.
As shown in Fig. 2 the selector button includes the button state of different stalls, MCU is according to the different buttons received
State, judge transforming gear amplitude；When speed changer be in it is most high-grade or it is minimum at that time, not speed change.The MCU is according to selector button
After gear instruction, control stepper motor rotates the corresponding angle of the gear.The stepper motor pulls after rotating certain angle
Corresponding length is loosened in speed change linear shrinkage, realizes the speed change of different stalls.
As shown in figure 3, speed-change control device of the present utility model, when being installed on bicycle, selector button is arranged on handlebar
On, MCU, stepper motor and cable quadrant form the entirety of transmission actuator, on the cant beam below bicycle, cable quadrant
The speed changer of bicycle is connected to by shift cable.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
People can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.It is all
The modification done according to the Spirit Essence of the utility model main technical schemes, it should all cover in the scope of protection of the utility model
Within.
