[0034] Please refer to the structures shown in Figures 1 to 6. This application is a transmission shifter applied to a human-powered vehicle.

[0035] Please refer to Figures 1 and 2. An embodiment of the present application provides a transmission shifter, comprising: a shifter base 1 and two shifter units 2; each shifter unit 2 is provided with a first pivot member 23 at one end and is axially connected to the shifter base 1 via the first pivot member 23. The first pivot member 23 can be set loosely or tightly, and the shifter unit 2 can be rotated and adjusted relative to the shifter base 1 around the axis of the first pivot member 23; wherein each shifter unit 2 is provided with a positioning member 24, and when the shifter unit 2 is rotated and adjusted around the first pivot member 23, the positioning member 24 cooperates with the shifter base 1 to position it.

[0036] In this embodiment, the two shift units 2 are respectively a downshift shift unit 2 and an upshift shift unit 2. To facilitate adjustment of the rotation angles of the two shift units 2, the first pivot member 23 is set to be loose or tight. Specifically, the shift unit 2 can be operated to rotate around the first pivot member 23 at one end by simply loosening the first pivot member 23, and the positioning member 24 is used to assist the shift unit 2 in rotating and positioning to a desired position. After rotating to the desired angle, the first pivot member 23 is tightened to complete the rotation adjustment. This has the advantages of simple structure and convenient adjustment.

[0037] Referring to Figures 3 and 4, in one embodiment, two mounting positions 11 are provided on the shifter base 1, each mounting position 11 having a mounting hole 111. A first pivot member 23 passes through one end of the shifter unit 2 and the positioning member 24 and is threadedly connected to the corresponding mounting hole 111. When the first pivot member 23 is threadedly screwed into the corresponding mounting hole 111, the shifter unit 2 can be fixed to the corresponding mounting position 11 through the positioning member 24. When the first pivot member 23 is threadedly loosened from the corresponding mounting hole 111, the shifter unit 2 can be rotated and adjusted and positioned in cooperation with the corresponding mounting position 11 through the positioning member 24.

[0038] In this embodiment, the mounting hole 111 can be a threaded hole, and the first pivot member 23 can be a half-thread screw, and the thread on the half-thread screw is located at the end of the half-thread screw; based on this, the end of the first pivot member 23 passes through one end of the finger shift unit 2 and the positioning member 24 and is threadedly connected to the mounting hole 111 to achieve a threaded connection. By operating the first pivot member 23 to be screwed into the mounting hole 111, the finger shift unit 2 and the positioning member 24 can be pressed against the mounting position 11, and the finger shift unit 2 can be prevented from rotating loose by cooperating with the mounting position 11 through the positioning member 24; by operating the first pivot member 23 to be screwed out of the mounting hole 111, the finger shift unit 2 and the positioning member 24 can be loosened relative to the mounting position 11, so that the angle of the finger shift unit 2 can be rotated to adjust.

[0039] Specifically, a plurality of positioning recesses 112 are provided on the mounting position 11, and the plurality of positioning recesses 112 are distributed in a circular annular pattern on the circumferential outside of the mounting hole 111; a plurality of positioning protrusions 241 are provided on the side of the positioning member 24 that contacts the mounting position 11; and the plurality of positioning recesses 112 correspond one-to-one to the plurality of positioning protrusions 241. Based on this, when the first pivot member 23 is tightened, the finger shift unit 2 is positioned in cooperation with the mounting position 11 through the positioning member 24, and the multiple positioning protrusions 241 of the positioning member 24 correspond one-to-one to the multiple positioning recesses 112 of the mounting position 11, which can prevent the finger shift unit 2 from loosening; and when the first pivot member 23 is loose, the finger shift unit 2 can be rotated and adjusted and drive the positioning member 24 to rotate synchronously. During the rotation adjustment process, the positioning protrusion 241 on the positioning member 24 rotates relative to the positioning recess 112 of the mounting position 11, thereby generating an adjustment feedback sense, so that the user can perceive the angle of the rotation adjustment; it should be understood that because the multiple positioning recesses 112 and the multiple positioning protrusions 241 are distributed in a circular ring shape, the number of positioning recesses 112 and positioning protrusions 241 can be set to limit the angle of each rotation adjustment.

[0040] More specifically, when the finger shift unit 2 is rotated and adjusted relative to the finger shifter base 1 around the axis of the first pivot member 23, it is necessary to drive the positioning member 24 to rotate synchronously, so as to produce an adjustment feedback feeling; based on this, a limit opening 211 can be provided at the bottom of one end of the finger shift unit 2. When the first pivot member 23 is in a tightened state or a loose state, the side of the positioning member 24 facing away from the installation position 11 is always embedded in the limit opening 211, thereby limiting the rotation of the positioning member 24 relative to the limit opening 211 in the axial direction of the first pivot member 23. In this way, the positioning member 24 can be driven to rotate synchronously when the finger shift unit 2 is rotated and adjusted.

[0041] More specifically, in order to ensure that the finger shift unit 2 can drive the positioning member 24 to rotate synchronously when it is rotated and adjusted, a convex beam 212 can be provided in the limiting opening 211, and a groove 242 can be provided on the side of the positioning member 24 away from the installation position 11. The limiting opening 211 and the positioning member 24 are limited and matched by the convex beam 212 and the groove 242.

[0042] When the first pivot member 23 is tightened, the limiting opening 211 is pressed toward the mounting position 11, and the positioning member 24 is fixed in the mounting position 11, and is positioned by the positioning protrusion 241 of the positioning member 24 and the positioning recess 112 of the mounting position 11 to ensure stability; when the second pivot member 25 is loosened, the gap between the limiting opening 211 and the mounting position 11 is slightly increased, so that the positioning member 24 has a small space between the limiting opening 211 and the mounting position 11, which allows the positioning member 24 to move along the axial direction of the first pivot member 23. At this time, the side of the positioning member 24 facing away from the mounting position 11 is still limited by the limiting opening 211. Therefore, when the finger shift unit 2 is rotated, the positioning member 24 is driven to rotate, and the positioning member 24 rotates relative to the mounting position 11 to achieve feedback adjustment.

[0043] Referring to FIG. 5 , in one embodiment, each shifter unit 2 includes a switch mounting base 21 and a button 22 . One end of the switch mounting base 21 is axially coupled to the shifter base 1 via a first pivot member 23 . One end of the button 22 is axially coupled to the switch mounting base 21 via a second pivot member 25 , and the button 22 can be pressed relative to the switch mounting base 21 about the axis of the second pivot member 25 .

[0044] In this embodiment, the switch mounting base 21 serves as a carrier for the button 22. One end of the switch mounting base 21 can be rotated and adjusted relative to the shifter base 1 around the first pivot member 23. That is, the switch mounting base 21 also drives the button 22 to rotate and adjust. The button 22 is the position where the shifting operation is actually performed. In this way, the position of the button 22 can be adjusted to suit the shifting operation requirements of different users.

[0045] In this embodiment, the button 22 is in the shape of a shell and is half wrapped on the switch mounting base 21. The other end of the button 22 is connected to the switch mounting base 21 through an elastic member 214 such as a compression spring. The speed shifting adjustment can be achieved by elastically pressing the other end of the button 22.

[0046] In one embodiment, the two switch mounting bases 21 are located on the same side of the shifter base 1 and are arranged opposite each other. A wiring groove 213 is provided on the opposite sides of the two switch mounting bases 21. A winding post 215 is provided in the wiring groove 213 corresponding to the positions of the first pivot member 23 and the second pivot member 25, so that the shift cable can be guided along the curved surface of the winding post 215 in the wiring groove 213 and enter the shifter base 1.

[0047] In this embodiment, one end of the speed shift cable is connected to the button 22, and the other end of the speed shift cable is introduced into the interior of the shifter base 1. By elastically pressing the other end of the button 22, the speed shift cable will be linked to move to achieve the speed shifting operation; and the speed shift cable needs to be routed from the switch mounting base 21 to the interior of the shifter base 1. For this purpose, a routing groove 213 is provided. The speed shift cable is led along the curved surface of the winding column 215 in the routing groove 213 and enters the shifter base 1. In this way, the speed shift cable contacts and rubs against the curved surface of the winding column 215 when moving, and is not easily broken.

[0048] In this embodiment, the wiring grooves 213 of the two switch mounting bases 21 are arranged on opposite sides of the two switch mounting bases 21, which has the effect of hiding the speed change cable and makes the overall appearance more beautiful.

[0049] Referring to FIG. 6 , in one embodiment, a cavity 12 with an open top is provided within the base 1 of the finger shifter; a battery is provided within the cavity 12, a control board assembly 13 is stacked on the battery, and the top opening of the cavity 12 is sealed with a cover 14; a fine-tuning button 17 and an indicator light 18 connected to the control board assembly 13 are provided on the front side of the finger shifter base 1.

[0050] In this embodiment, the shifter base 1 is approximately in the shape of a square. Taking the transmission shifter installed on the left handlebar of a human-powered vehicle as an example, the two shifter units 2 are arranged on the left side of the shifter base 1 and are opposite to each other. The positions of the two shifter units 2 correspond to the operating space of the left handlebar, and after the two shifter units 2 are adjusted to a comfortable position by rotation, the user's shifting operation is more comfortable.

[0051] In this embodiment, the battery, the control board assembly 13 and the cover plate 14 are sequentially stacked in the cavity 12 of the finger shifter base 1, which has the effects of reasonable space utilization, compact structure and waterproofness.

[0052] In this embodiment, the fine-tuning button 17 and the indicator light 18 can both be set on the front side of the shifter base 1, so that the user can press the fine-tuning button 17 and check the status of the indicator light 18; the fine-tuning button 17 is used to fine-tune the current speed gear but not shift gears, and can be adapted to various flywheel chain installations; the indicator light 18 is used to feedback the operation information of the button 22 and the battery power, etc.

[0053] In this embodiment, the shifter base 1 is provided with a boss 15, on which a clamping ring 16 is mounted. The shifter base 1 is clamped to the handlebars of a human-powered vehicle via the clamping ring 16, with the two shifter units 2 aligned on the sides of the handlebars. Specifically, the clamping ring 16 can be a hinged clamping method for easy installation.

[0054] An embodiment of the present application also provides a human-powered vehicle, comprising the transmission shifter as described above.

[0055] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
