Each of the plurality of shift buttons 500 is connected to a connector 510. The buckle plate 700 is detachably connected to the inner wall of the top cover 400, and a groove for the limiting connector 510 is formed between the buckle plate 700 and the inner wall of the top cover 400.

[0037] When assembling the derailleur control device, the main board 200 is installed in the inner cavity of the housing 100, several shift buttons 500 are respectively inserted into several first through holes 410, several connectors 510 are confined in several slots, then the buckle plate 700 is connected to the inner wall of the upper cover 400, then the upper cover 400 is connected to the housing 100, and then one of the first clamp and the second clamp is connected to the connecting part 110 to complete the assembly of the derailleur control device. The assembly method of the derailleur control device is simple and easy to operate.

[0038] Several shift buttons 500 are exposed outside the top cover 400. Pressing the shift buttons 500 improves the convenience and user experience of operation.

[0039] The gear shift button 500 is larger than the gear shift button. The outer surface of the gear shift button 500 has anti-slip texture to prevent fingers from slipping when pressing it, thus improving the user experience.

[0040] It is conceivable that the buckle plate 700 can be connected to the inner wall of the upper cover 400 through a snap-fit ​​structure. Of course, the buckle plate 700 can also be connected to the inner wall of the upper cover 400 through a third fastener, which facilitates the removal of the buckle plate 700 and thus facilitates the installation and removal of the connector 510.

[0041] In this embodiment, there are two shift buttons 500, which include an upshift button and an downshift button. The two shift buttons 500 are respectively used in conjunction with the upshift button and the downshift button.

The bottom cover 113 and the housing 100 can be connected by a snap-fit ​​structure or by a threaded connection.

[0044] Reference Figure 1 and Figure 2 In some embodiments, there are two shift buttons 500. The axial direction of the limiting hole formed by the first clamp and the axial direction of the limiting hole formed by the second clamp are at an acute angle. The first clamp and the second clamp have the same structure, the same function and the same usage method. The flip-over adapter 300 can be used to make the positions of the two shift buttons 500 of the derailleur control device adjustable, thereby improving the convenience of the derailleur control device.

[0045] In this embodiment, the axial direction of the limiting hole formed by the first clamp and the axial direction of the limiting hole formed by the second clamp form an acute angle, which is 15° to 25°.

[0046] In some embodiments, the adapter 300 includes a support arm 310, with a first clamping arm 320 and a second clamping arm 330 hinged to both ends of the support arm 310. The first clamping arm 320 and the second clamping arm 330 are connected to both ends of the support arm 310 by two first fasteners 340 to form a first clamp and a second clamp. By unscrewing the two first fasteners 340, the first clamping arm 320 and the second clamping arm 330 can be flipped over, that is, the first clamp and the second clamp can be opened, so that the support arm 310 and the first clamping arm 320 can be fitted onto the handlebars or the connecting part 110, and the support arm 310 and the second clamping arm 330 can be fitted onto the handlebars or the connecting part 110. Then, the first clamping arm 320 and the second clamping arm 330 can be flipped over in the opposite direction, and then the two first fasteners 340 can be screwed on, so that the support arm 310 and the first clamping arm 320 clamp the handlebars or the connecting part 110, and the support arm 310 and the second clamping arm 330 clamp the handlebars or the connecting part 110.

[0047] One end of the support arm 310 is hinged to the first clamping arm 320 via a first pin, and the other end of the support arm 310 is hinged to the second clamping arm 330 via a second pin. The first fastener 340 is a first screw or a first bolt.

[0048] It is understood that the first clamping arm 320, the second clamping arm 330, and the support arm 310 all have arc-shaped ends. The two ends of the support arm 310 form an included angle, which is an obtuse angle. In this embodiment, the obtuse angle is 155° to 165°.

[0049] Reference Figures 1 to 3 In some embodiments, the connecting part 110 is provided with an annular limiting groove 111, and one of the first clamp and the second clamp clamps the inner wall of the limiting groove 111. The limiting groove 111 can fix the first clamp or the second clamp in a fixed position on the connecting part 110, ensuring the stability and firmness of clamping the connecting part 110.

[0050] Reference Figure 2 In some embodiments, the derailleur control device further includes a sealing cover 800, which covers the opening of the inner cavity to seal the opening, ensuring the airtightness of the inner cavity and preventing water and dust from entering the inner cavity and damaging the main board 200 and other components inside the inner cavity. The sealing cover 800 is capable of elastic deformation. The shift button 500, the sealing cover 800, and the main board 200 are arranged sequentially from top to bottom. The shift button 500 can trigger the shift button of the main board 200 through the sealing cover 800.

[0051] Reference Figure 2 and Figure 3In some embodiments, the derailleur control device further includes a pressure plate 900 connected to the housing 100. The pressure plate 900 and the housing 100 clamp the periphery of the sealing cover 800 to fix the sealing cover 800. The pressure plate 900 fixes the sealing cover 800 to the housing 100.

[0052] The housing 100 is provided with a positioning groove, which surrounds the opening of the inner cavity. The upper and lower surfaces of the sealing cover plate 800 are both surrounded by positioning protrusions. The positioning protrusions on the lower surface of the sealing cover plate 800 extend into the positioning groove. The pressure plate 900 presses against the positioning protrusions on the upper surface of the sealing cover plate 800, and the pressure plate 900 presses the sealing cover plate 800 tightly onto the housing 100, so that the sealing of the opening of the inner cavity is guaranteed.

[0053] The periphery of the pressure plate 900 is connected to the housing 100 by a plurality of second fasteners.

[0054] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, there are two shift buttons 500, which are symmetrically arranged on the left and right sides. Both shift buttons 500 are connected to the connector 510 through connecting ears. The connecting ears of the two shift buttons 500 are staggered in the front-back direction and the left-right direction. The length of the connecting ears is long enough. The shift buttons 500 are connected to the upper cover 400 through the connecting ears and the connector 510.

[0055] The connecting ear is flexible, which facilitates the placement of the connecting ear, the connector 510 and the shift button 500. When the buckle plate 700 is connected to the upper cover 400 through the snap-fit ​​structure, the connector 510 is easily positioned in the groove between the inner wall of the buckle plate 700 and the upper cover 400.

[0056] Reference Figure 5 In this embodiment, one shift button 500 has two first connecting ears with the same structure. The projections of the two first connecting ears on a plane overlap. Another shift button 500 has one second connecting ear. Both first connecting ears and one second connecting ear are connected to a connector 510. The second connecting ear is located between the two first connecting ears. The three connectors 510 have the same axis. The two connectors 510 on the two first connecting ears are coaxially arranged. The connectors 510 on the first connecting ear and the connectors 510 on the second connecting ear are not coaxially arranged.

[0057] In some embodiments, there are two shift buttons 500, each with an extension 520. The two extensions 520 are opposite to each other and extend to the upper part of the periphery of the housing 100, increasing the area of ​​the shift buttons 500 for contact with fingers and improving the comfort of pressing the shift buttons 500.

[0058] The shift button 500 and its extension 520 are both equipped with anti-slip textures to prevent slippage and further improve the tactile feel and experience of pressing the shift button 500.

[0059] Reference Figures 1 to 3 In some embodiments, the connecting portion 110 is provided with a mounting hole 112, which communicates with the inner cavity of the housing 100. A custom button 210 is provided within the mounting hole 112, and this custom button 210 cooperates with a custom button on the main board 200. The custom button 210 is used to trigger the custom button. Depending on the model of the main board 200 or control device, the function corresponding to the custom button may be signal pairing or fine-tuning of a toggle switch, etc.

[0060] In some embodiments, the derailleur control device further includes an end cap 600, which is connected to the connecting part 110. The end cap 600 is used to block the mounting hole 112. The end cap 600 is provided with a second through hole 610, through which a custom button 210 passes. The end cap 600 serves to seal the mounting hole 112 and support the custom button 210.

[0061] Understandably, the end cap 600 and the connecting part 110 are connected by a snap-fit ​​structure, which facilitates the installation and removal of the end cap 600. The outer surface of the end cap 600 is provided with a finger groove, and the second through hole 610 is opened at the bottom of the finger groove. A finger can be pressed into the finger groove to press the custom button 210. The custom button 210 only needs to extend into the finger groove, without extending the custom button 210 outside the end cap 600, thus avoiding interference between the custom button 210 and external parts or objects.

[0062] The snap-fit ​​structure is a common structure and will not be described in detail here. The first fastener 340, the second fastener, and the third fastener can all be screws or bolts.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] Of course, this utility model is not limited to the above-described embodiments.
