However, the two linkage levers are misaligned along the rod direction, making them awkward to press, prone to accidental presses, and easily distracting while riding.

[0003] Therefore, it is necessary to propose a new type of bicycle linkage shifter to solve the above problems, and to solve the problems of traditional shifters where the linkage lever is misaligned along the lever direction, making it difficult to press, easy to press the wrong lever, and easy to be distracted while riding. Summary of the Invention

[0004] This utility model provides a bicycle linkage shift lever, which solves the problems of traditional shift levers where the linkage lever is misaligned along the lever direction, making it difficult to press, easy to press the wrong lever, and easy to distract the rider.

[0048] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0049] Example 1, see Figures 1 to 12 A bicycle linkage shifter includes a main body 1 and a control module 2. The main body 1 has a lever 3, which is hinged to the main body 1 and rotates relative to it. The control module 2 obtains a signal based on the swing position of the lever 3 and sends a shift command to the gearbox. The lever 3 includes a first lever 31 and a second lever 32 that rotate coaxially. The first lever 31 and the second lever 32 overlap near the hinge, so that when the first lever 31 moves from the rest position to the operating position, it drives the second lever 32 to move from the rest position to the operating position as well. The ends of the first lever 31 and the second lever 32 are arranged back and forth along the axis of rotation. By setting a first lever 31 and a second lever 32 that rotate coaxially, the first lever 31 and the second lever 32 overlap vertically near the hinge, so that when the first lever 31 moves from the rest position to the operating position, it drives the second lever 32 to move from the rest position to the operating position as well. The ends of the first lever 31 and the second lever 32 are arranged back and forth along the axis of rotation. The linkage of the two levers can save space in the actuator body 11. The back and forth arrangement of the ends of the two levers along the axis of rotation, compared with the traditional arrangement along the direction of the lever, can more easily avoid mis-pressing and make pressing more convenient.

[0050] The first lever 31 has a first pressing part 41 at its end, and the second lever 32 has a second pressing part 42 at its end. The first pressing part 41 and the second pressing part 42 are arranged back and forth along the axis of rotation. This facilitates pressing. Preferably, the first pressing part 41 and the second pressing part 42 are made of rubber, which makes pressing comfortable.

[0051] The ends of the first lever 31 and the second lever 32 extend in a direction that is far apart from each other. This further increases the distance between the ends of the first lever 31 and the second lever 32, further preventing accidental pressing.

[0052] The control module 2 is also equipped with a sensor 5. The lever 3 extends downward to form a hanging rod 30, and a detection body 50 is installed on the hanging rod 30. The sensor 5 senses the detection body 50.

[0053] The boom 30 includes a first boom 310 disposed on a first lever 31 and a second boom 320 disposed on a second lever 32. The detection body 50 includes a first detection body 510 mounted on the first boom 310 and a second detection body 520 mounted on the second boom 320. The sensor 5 includes a first sensor 51 for sensing the first detection body 510 and a second sensor 52 for sensing the second detection body 520.

[0054] The first sensor 51 is located outside the first detection body 510, and the second sensor 52 is located outside the second detection body 520. This reduces the overall height of the shifter, allowing it to fit more closely to the frame and providing space for a shift feedback device at the bottom.

[0055] The aforementioned gear shift feedback device includes an elastic element 6 and a shaped panel 7. The elastic element 6 is mounted on the lever 3, and the upper surface of the shaped panel 7 has a protrusion 70. When the lever 3 is pressed, the bottom of the elastic element 6 tightly adheres to and passes over the protrusion 70, and the elastic element 6 is compressed during the process. This simple structure can achieve gear shift feedback, allowing users to sense whether the gear shift is complete, and it is convenient and quick to install and maintain.

[0056] The elastic element 6 includes a spring 60 and a ball bearing 61. The bottom of the lever 3 is provided with a downwardly extending cylinder 33. The spring 60 is located inside the cylinder 33. The ball bearing 61 abuts against the end of the spring 60. When the lever 3 is pressed, the ball bearing 61 moves with the cylinder 33 and closely passes over the protrusion 70. The spring 60 is squeezed during the passing process.

[0057] Preferably, the irregularly shaped panel 7 is a metal plate, which can generate sound during the positioning feedback process, thereby enhancing the positioning feedback effect.

[0058] The elastic element 6 includes an elastic ball. The elastic ball is compressed during its passage, which also generates positioning feedback.

[0059] It also includes a side plate 8. The main body 1 includes a housing 10 and a first cavity 11 within the housing 10 for accommodating the lever 3 and the irregularly shaped panel 7. The housing 10 has a side opening 12 on its side. The lever 3 extends out of the side opening 12 from the first cavity 11. The side plate 8 has a groove 80 for clamping the edge of the irregularly shaped panel 7. After the side plate 8 avoids the lever 3, it closes the side opening 12. The side plate 8 can close the side opening 12, thereby protecting the components inside the first cavity 11; the groove 80 can stably insert and fix the irregularly shaped panel 7.

[0060] The first cavity 11 is also provided with a step 13 for supporting the irregular panel 7. The step 13 can further stably insert and fix the irregular panel 7.

[0061] The system also includes a bottom cover 14. The control module 2 is further provided with an external connecting cable. The bottom cover 14 has a wire hole 15 that allows the external connecting cable to pass through. The bottom of the main body 1 has a second cavity 16, into which the external connecting cable extends. The bottom of the second cavity 16 has a bottom opening 17, which is closed by the bottom cover 14. The bottom cover 14 with the wire hole 15 facilitates the installation of the wired control module 2 and protects its components.

[0062] Preferably, the bottom cover 14 is threadedly connected to the bottom opening 17.

[0063] It also includes a nut 18 and a first sealing gasket 19. A fixed sleeve 9 is fitted around the outside of the external connecting wire. The sleeve 9 has threads on its outer side and passes through the wire hole 15. The nut 18 is located at the bottom of the wire hole 15 and is threadedly connected to the sleeve 9. The first sealing gasket 19 is clamped between the bottom of the wire hole 15 and the nut 18. In this way, the wire hole 15 is sealed by the pressure of the nut 18 on the first sealing gasket 19.

[0064] It also includes a second sealing gasket 91, and a retaining ring 92 is provided at the top of the wire sleeve 9. The retaining ring 92 is larger than the wire hole 15 and is located inside the second cavity 16. The second sealing gasket 91 is sandwiched between the retaining ring 92 and the top of the wire hole 15. In this way, the wire hole 15 can be sealed by the mutual compression of the second sealing gasket 91 by the retaining ring 92 and the bottom cover 14.

[0065] Example 2, see Figure 13 and Figure 14 Unlike Embodiment 1, the control module 2 also includes a wireless transmitter. The bottom of the main body 1 has a battery compartment 20 for accommodating the battery. The battery compartment 20 contains a conductor electrically connected to the wireless transmitter, and a clamping member 21 for holding the battery is also provided within the battery compartment 20. This facilitates the installation of the wireless control module 2 and protects its components.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.

[0067] The embodiments and descriptions provided are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
