[0002] Bicycles include mountain bikes, road bikes, leisure bikes, extreme sports bikes, etc. In order to change the speed during riding, these bicycle products usually install a mechanical transmission system to adjust the speed (gear ratio). Usually, a mechanical transmission system consists of a front / rear transmission actuator (sometimes also referred to as a transmission), a shifter, and a steel wire connecting the transmission actuator and the shifter. By turning the shifter installed on the handlebar, the steel wire is stretched, thereby driving the transmission actuator to switch the chain plate, and finally changing the gear ratio of the front and rear drive sprockets to achieve the purpose of changing the riding speed of the bicycle.

[0003] Bicycle speed change systems have been widely used. In order to prevent the speed change cable from being directly exposed to the air, a cable tube is usually used to wrap it. The cable tube and the speed change cable are relatively soft and easy to bend, so that the speed change cable is very likely to rub against the inner wall of the cable tube during movement. However, due to the different installation positions of different models, some existing finger shift devices make it difficult for the speed change cable to always remain parallel to the cable tube port when extending from the finger shift device, so that the speed change cable is easy to rub against the cable tube port, which is easy to increase the wear of the speed change cable and the driving burden of the motor, reduce the transmission efficiency, and make the user more laborious and not smooth when using it. Utility Model Content

[0004] The utility model aims to provide a bicycle electronic shift command execution device to solve the problem that the speed change line of the existing shift device is difficult to always keep parallel with the line tube end, resulting in easy friction between them.

[0010] A power device is installed on the base to drive the rotating shaft to rotate.

[0011] Furthermore, the swinging member is a balance wheel, and the center portion of the balance wheel is connected to the rotating shaft.

[0012] Furthermore, a wire groove is processed on the outer contour of the swinging member, and the connecting portion is located at the end of the wire groove.

[0013] Furthermore, a gap-avoiding portion is provided on the swinging member, and the gap-avoiding portion is located on a side of the connecting portion away from the wire groove.

[0038] Reference Figure 1-2 The figure shows an embodiment of the present invention.

[0039] The utility model provides a bicycle electronic finger-shift instruction execution device, comprising:

[0040] Base 10;

[0041] A rotating shaft 20 rotatably mounted on the base 10;

[0042] A swinging member 30 fixedly connected to the rotating shaft 20, wherein a connecting portion 303 is provided on the swinging member 30;

[0043] A gearshift cable 40, one end of which is connected to the connecting portion 303, and the other end of which is connected to the transmission of the bicycle;

[0044] A power device 50 is installed on the base 10 to drive the rotating shaft 20 to rotate.

[0045] The swinging member 30 is a balance wheel, and the center of the balance wheel is connected to the rotating shaft 20 .

[0046] In the embodiment of the utility model, the base 10 is a square hollow cavity, and a gear assembly for driving the rotating shaft 20 to rotate is arranged inside the cavity, and a reducer is also installed. The reducer is connected to the output shaft of the power device 50. The reducer in the utility model example is a conventional reducer. The specific working principle and connection method are common knowledge in the field and are not elaborated here. The gear assembly includes a driven gear connected to the rotating shaft 20 and a driving gear connected to the reducer. The driving gear is meshed with the driven gear. The power device 50 and the reducer drive the driving gear to rotate, and the driving gear drives the driven gear to rotate, and the driven gear drives the rotating shaft 20 to rotate. In order to meet the torque requirements, a multi-stage reduction system design with a worm gear as the core can also be adopted to ensure that the electronic finger shifting system can not only be connected to the traditional mechanical transmission actuator, but also has sufficient torque to drive transmission actuators of different speed levels.

[0047] One end of the rotating shaft 20 inside the base 10 is linked to a power device 50 such as an electric motor through a gear assembly, and one end of the rotating shaft 20 outside the base 10 is fixedly connected to the swing member 30.

A connecting portion 303 is also provided on the swing member 30, one end of the speed change cable 40 is connected to the connecting portion 303, and the other end of the speed change cable 40 is connected to the electronic shift of the bicycle. When the electronic shift sends a speed change command, the power device 50 is started and drives the rotating shaft 20 to rotate so that the swing member 30 follows the swing. When the swing member 30 swings, the speed change cable 40 extends and retracts accordingly.

[0048] The swing member 30 is a swing arm, one end of which is connected to the rotating shaft 20 , and the other end of which is connected to the speed change cable 40 .

[0049] like Figure 3-4 As shown, in another optional implementation of the present embodiment, the swing member 30 is a swing arm, the middle part of the upper end of the swing arm is connected to the rotating shaft 20, the rotating shaft 20 can drive the swing arm to swing, a limit roller 101 is arranged between the lower end of the swing arm and the wire tube 41 bracket, and a limit column 102 is arranged on the counterclockwise rotation path of the lower end of the swing arm. The limit roller 101 and the limit column 102 are used to limit the rotation of the swing arm within a certain range. The limit roller 101 is provided with a groove on the circumferential profile to reduce the friction between the speed change cable 40 and the limit roller when the speed change cable 40 is guided, and the lateral displacement of the speed change cable 40 can also be limited. When the swing member 30 is a swing arm, the speed change cable 40 is stretched and retracted by the swing arm swinging, thereby pulling the transmission.

[0050] The outer contour of the swing member 30 is processed with a wire groove 301 , and the connecting portion 303 is located at the end of the wire groove 301 .

[0051] The swing member 30 is provided with a gap-avoiding portion 302 , and the gap-avoiding portion 302 is located at a side of the connecting portion 303 away from the wire groove 301 .

[0053] In the present embodiment, a wire groove 301 is processed on the outer contour of the swing member 30, and the speed change cable 40 can be rolled into the wire groove 301 when the balance wheel swings to prevent the speed change cable 40 from lateral displacement. The connecting portion 303 is located at the end of the wire groove 301 to facilitate the installation and connection of the speed change cable 40; in order to facilitate operation during installation and reserve an installation position for the wire end cap 401 provided at one end of the speed change cable 40, a gap 302 is also provided on the side of the connecting portion 303 away from the wire groove 301, and the wire end cap 401 is located in the gap 302 and abuts against the side of the connecting portion 303 away from the wire groove 301.

[0054] The middle portion of the swing member 30 is provided with an anti-slip structure adapted to the rotating shaft 20 .

[0055] A wire tube 41 is sleeved on the outer periphery of the shift wire 40 , and a wire tube 41 bracket for fixing the wire tube 41 is disposed on the base 10 .

[0056] In another implementation scheme of the present embodiment, in order to prevent the swing member 30 from loosening or falling off during rotation, an anti-slip structure compatible with the rotating shaft 20 is provided in the middle of the swing member 30. In this scheme, a D-shaped through hole is provided in the middle of the swing member 30, and the outer end of the rotating shaft 20 is also a D-shaped shaft body and compatible with the through hole. Replacing the cylindrical type with a D-type can effectively prevent rotation; in order to protect the speed change cable 40 and prevent additional wear and rust, a wire tube 41 is provided on the outer periphery of the speed change cable 40. At the same time, in order to stably connect the speed change cable 40 with the swing member 30 and prevent the wire tube 41 from loosening, a wire tube 41 bracket is also provided on the base 10 for fixing the wire tube 41.

[0057] When the utility model is implemented, the intelligent electronic shifting system on the bicycle is first started. When the bicycle needs to be shifted, the shift button on the intelligent electronic shifting system is pressed. At this time, the controller receives a signal to control the bicycle electronic shifting instruction execution device to execute the shifting action. The power device 50 drives the rotating shaft 20 to rotate, so that the swinging member 30 swings smoothly around the axis of the rotating shaft 20, driving the speed change cable 40 to retract and retract, and the transmission connected to the speed change cable 40 smoothly shifts speed accordingly, thereby achieving smooth speed shifting of the bicycle.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
