Description

Technical Field

[0001] This invention relates to the field of bicycle accessories technology, and in particular to a derailleur shifter and a human-powered vehicle. Background Technology

[0002] In human-powered vehicles with derailleurs, the derailleur shifter is usually located on the handlebars. The derailleur shifter is generally constructed as a shifter base and two shifter units. Users can adjust the gears of the human-powered vehicle by operating the two shifter units while riding.

[0003] Traditional gear shifters typically have two shifter units that are not adjustable in position. Later, to meet the needs of different users, two shifter units were designed so that their positions could be adjusted according to the user's preferences. However, the existing adjustment structure is relatively complex and the adjustment process is not convenient enough. Summary of the Invention

[0004] The purpose of this invention is to provide a gear shifter and a human-powered vehicle, aiming to solve the problems of complex adjustment structure and inconvenient adjustment of the shifter unit in existing gear shifters.

[0005] To solve the above-mentioned technical problems, the objective of this invention is achieved through the following technical solution: providing a gear shifter for use in human-powered vehicles, the gear shifter comprising: a shifter base and two shifter units; each shifter unit has a first pivot at one end and is axially connected to the shifter base via the first pivot, the first pivot can be loosely or loosely set, and the shifter unit can be rotated and adjusted relative to the shifter base around the axis of the first pivot;

[0006] Each of the aforementioned finger shifters is provided with a positioning element, and when the finger shifter is rotated and adjusted around the first pivot, it is positioned by the positioning element in conjunction with the finger shifter base.

[0007] Furthermore, the base of the shifter is provided with two mounting positions, each of which is provided with a mounting hole. The first pivot passes through one end of the shifter unit and the positioning member and is threadedly connected to the corresponding mounting hole.

[0008] When the first pivot thread is tightened into the corresponding mounting hole, the shifter unit can be fixed by engaging with the corresponding mounting position through the positioning member; when the first pivot thread is loosened from the corresponding mounting hole, the shifter unit can be rotated and adjusted and positioned by engaging with the corresponding mounting position through the positioning member.

[0009] Furthermore, the mounting position is provided with multiple positioning recesses, which are distributed in a circular circumferential direction on the outer side of the mounting hole; the side of the positioning member that contacts the mounting position is provided with multiple positioning protrusions; the multiple positioning recesses correspond one-to-one with the multiple positioning protrusions.

[0010] Furthermore, the shifter unit is provided with a limiting port, and the side of the positioning member facing away from the mounting position is embedded in the limiting port. When the shifter unit is rotated and adjusted relative to the shifter base around the axis of the first pivot member, it drives the positioning member to rotate relative to the corresponding mounting position and cooperate in positioning.

[0011] Furthermore, the limiting port is provided with a protruding beam, and the positioning member is provided with a groove on the side opposite to the mounting position. The limiting port and the positioning member are limited by the protruding beam and the groove to restrict the positioning member from rotating relative to the limiting port in the axial direction of the first pivot member.

[0012] Furthermore, each of the aforementioned finger-mounting units includes a switch mounting base and a button; one end of the switch mounting base is connected to the finger-mounting base via a first pivot member; one end of the button is connected to the switch mounting base via a second pivot member, and the button can be pressed relative to the switch mounting base around the axis of the second pivot member.

[0013] Furthermore, the two switch mounting bases are located on the same side of the shifter base and are arranged opposite to each other. Each of the two switch mounting bases has a cable routing groove on its opposite side. The cable routing groove has a winding post corresponding to the position of the first pivot and the second pivot, so that the shift cable can be led along the arc surface of the winding post in the cable routing groove and enter the shifter base.

[0014] Furthermore, the dial indicator body has a cavity with a top opening; a battery is disposed in the cavity, a control board assembly is stacked on the battery, and a cover plate is used to seal the top opening of the cavity.

[0015] The front side of the dial base is provided with a fine-tuning button and an indicator light that are connected to the control board assembly.

[0016] Furthermore, the base of the shifter is provided with a boss, and a clamping ring is installed on the boss. The base of the shifter is clamped to the handlebar of the human-powered vehicle through the clamping ring, and the two shifter units are positioned corresponding to the side of the handlebar.

[0032] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0033] Please see Figures 1 to 6 The structure shown indicates that the present invention is a gearshift lever for use in human-powered vehicles.

[0034] Please refer to the following first. Figure 1 and Figure 2 This invention provides a gearshift shifter, comprising: a shifter base 1 and two shifter units 2; each shifter unit 2 has a first pivot 23 at one end and is axially connected to the shifter base 1 via the first pivot 23, the first pivot 23 being adjustable, and the shifter unit 2 being rotatable relative to the shifter base 1 around the axis of the first pivot 23; wherein each shifter unit 2 is provided with a positioning member 24, and when the shifter unit 2 is rotated around the first pivot 23, it is positioned in conjunction with the shifter base 1 via the positioning member 24.

[0035] In this embodiment, the two shifter units 2 are a downshift shifter unit 2 and an upshift shifter unit 2, respectively. To facilitate the adjustment of the rotation angle of the two shifter units 2, the first pivot member 23 is loosely and tightly set. Specifically, after loosening the first pivot member 23, the shifter unit 2 can be operated to rotate around the first pivot member 23 at one end for adjustment. With the help of the positioning member 24, the shifter unit 2 is rotated and positioned to the required position. After rotating to the required angle, the first pivot member 23 is tightened to complete the rotation adjustment. It has the advantages of simple structure and convenient adjustment.

[0036] Please see Figure 3 and Figure 4 In one embodiment, the shifter base 1 is provided with two mounting positions 11, each mounting position 11 having a mounting hole 111. A first pivot 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 23 is threadedly tightened into the corresponding mounting hole 111, the shifter unit 2 can be fixed by cooperating with the corresponding mounting position 11 through the positioning member 24. When the first pivot 23 is threaded loose from the corresponding mounting hole 111, the shifter unit 2 can be rotated and adjusted and positioned by cooperating with the corresponding mounting position 11 through the positioning member 24.

[0037] In this embodiment, the mounting hole 111 can be a threaded hole, and the first pivot 23 can be a half-threaded screw, with the thread on the half-threaded screw located at the end of the half-threaded screw. Based on this, the end of the first pivot 23 passes through one end of the shifter unit 2 and the positioning member 24 and is threaded into the mounting hole 111, thus achieving a threaded connection. By operating the first pivot 23 to screw into the mounting hole 111, the shifter unit 2 and the positioning member 24 can be pressed against the mounting position 11. The shifter unit 2 can prevent rotational loosening by cooperating with the mounting position 11 through the positioning member 24. By operating the first pivot 23 to screw out of the mounting hole 111, the shifter unit 2 and the positioning member 24 can be loosened relative to the mounting position 11, thereby allowing the angle of the shifter unit 2 to be rotated and adjusted.

[0038] Specifically, the mounting position 11 is provided with multiple positioning recesses 112, and the multiple positioning recesses 112 are distributed in a circular circumferential direction on the outer side of the mounting hole 111; the side of the positioning member 24 that contacts the mounting position 11 is provided with multiple positioning protrusions 241; the multiple positioning recesses 112 correspond one-to-one with the multiple positioning protrusions 241. Based on this, when the first pivot 23 is tightened, the shifter unit 2 is positioned in conjunction with the mounting position 11 through the positioning member 24. The multiple positioning protrusions 241 of the positioning member 24 correspond one-to-one with the multiple positioning recesses 112 of the mounting position 11, which can prevent the shifter unit 2 from becoming loose. When the first pivot 23 becomes loose, the shifter unit 2 can be rotated and adjusted, which will drive the positioning member 24 to rotate synchronously. During the rotation adjustment, the positioning protrusions 241 on the positioning member 24 rotate relative to the positioning recesses 112 of the mounting position 11, thereby generating adjustment feedback so that the user can perceive the size of the rotation adjustment angle. It should be understood that since the multiple positioning recesses 112 and the multiple positioning protrusions 241 are all arranged in a ring, the number of positioning recesses 112 and positioning protrusions 241 can be set to limit the angle of each rotation adjustment.

[0039] More specifically, when the shifter unit 2 rotates relative to the shifter base 1 around the axis of the first pivot 23, it needs to drive the positioning member 24 to rotate synchronously in order to generate adjustment feedback. Based on this, a limiting port 211 can be provided at the bottom of one end of the shifter unit 2. When the first pivot 23 is in a tight or loose state, the side of the positioning member 24 away from the mounting position 11 is always embedded in the limiting port 211, thereby restricting the rotation of the positioning member 24 relative to the limiting port 211 in the axial direction of the first pivot 23. In this way, the positioning member 24 can be driven to rotate synchronously when the shifter unit 2 is rotated for adjustment.

[0040] More specifically, in order to ensure that the positioning component 24 can rotate synchronously when the finger-shifting unit 2 is rotated and adjusted, a protruding beam 212 can be provided in the limiting port 211, and a groove 242 can be provided on the side of the positioning component 24 away from the mounting position 11. The limiting port 211 and the positioning component 24 are limited and cooperated by the protruding beam 212 and the groove 242.

[0041] Based on this, the principle of fixing or rotating the shifter unit 2 relative to the shifter base 1 is as follows: the positioning member 24 is limited between the limiting port 211 and the mounting position 11. When the first pivot member 23 is tightened, the limiting port 211 is pressed towards the mounting position 11, which makes the positioning member 24 tightened in the mounting position 11. The positioning member 24 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 port 211 and the mounting position 11 is slightly increased, so that there is a small space between the positioning member 24 and the limiting port 211 that can move along the axial direction of the first pivot member 23. At this time, the side of the positioning member 24 away from the mounting position 11 is still limited by the limiting port 211. Therefore, during the rotation of the shifter unit 2, the positioning member 24 will be driven to rotate, and the positioning member 24 will rotate relative to the mounting position 11 to achieve feedback adjustment.

[0042] Please see Figure 5 In one embodiment, each toggle unit 2 includes a switch mounting base 21 and a button 22; one end of the switch mounting base 21 is axially connected to the toggle base 1 via a first pivot member 23; one end of the button 22 is axially connected 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 around the axis of the second pivot member 25.

[0043] In this embodiment, the switch mounting base 21 serves as the carrier for the button 22. One end of the switch mounting base 21 can be rotated relative to the dial indicator base 1 around the first pivot 23. That is, the switch mounting base 21 also drives the button 22 to rotate. The button 22 is the position where the dial operation is actually performed. In this way, the position of the button 22 can be adjusted to suit the dial operation needs of different users.

[0044] In this embodiment, the button 22 is shell-shaped and partially encloses the switch mounting base 21. The other end of the button 22 is connected to the switch mounting base 21 by an elastic element 214 such as a compression spring. The speed shifting adjustment can be achieved by pressing the other end of the button 22 elastically.

[0045] In one embodiment, two switch mounting bases 21 are located on the same side of the shifter base 1 and are arranged opposite each other. Each of the two switch mounting bases 21 has a cable routing groove 213 on its opposite side. The cable routing groove 213 has a winding post 215 corresponding to the position of the first pivot member 23 and the second pivot member 25, so that the shift cable can be led along the arc surface of the winding post 215 in the cable routing groove 213 and enter the shifter base 1.

[0046] In this embodiment, one end of the shift cable is connected to the button 22, and the other end of the shift cable is introduced into the inside of the shifter base 1. By elastically pressing the other end of the button 22, the shift cable will move to achieve the shifting operation. The shift cable needs to be routed from the switch mounting base 21 to the inside of the shifter base 1. For this purpose, a cable routing groove 213 is provided. The shift cable is led along the arc surface of the post 215 in the cable routing groove 213 and enters the shifter base 1. In this way, the shift cable is in contact with and rubs against the arc surface of the post 215 when it moves, and is not easy to break.

[0047] In this embodiment, the wiring grooves 213 of the two switch mounting bases 21 are set on opposite sides of the two switch mounting bases 21, which has the effect of hiding the speed change cable and making the overall appearance more beautiful.

[0048] Please see Figure 6 In one embodiment, the dial base 1 has a cavity 12 with a top opening; a battery is provided in the cavity 12, and a control board assembly 13 is stacked on the battery; a cover plate 14 seals the top opening of the cavity 12; 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 dial base 1.

[0049] In this embodiment, the shifter base 1 is generally similar in shape to a cube. Taking the shifter installed on the left handlebar of a human-powered vehicle as an example, the two shifter units 2 are located 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. After the two shifter units 2 are adjusted to a comfortable position by rotation, the user's shifting operation is more comfortable.

[0050] In this embodiment, a battery, a control board assembly 13, and a cover plate 14 are sequentially stacked in the cavity 12 inside the finger dial base 1; this has the effect of reasonable space utilization, compact structure, and waterproofing.

[0051] In this embodiment, both the fine-tuning button 17 and the indicator light 18 can be located on the front side of the shifter base 1, making it convenient for the user to 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 gear without shifting gears, and can be adapted to various flywheel chains; the indicator light 18 is used to provide feedback on the operation information of the button 22 and the battery level, etc.

[0052] In this embodiment, the shifter base 1 is provided with a boss 15, and a clamping ring 16 is installed on the boss 15. The shifter base 1 is clamped to the handlebars of the manual vehicle by the clamping ring 16, and the two shifter units 2 are positioned corresponding to the sides of the handlebars. Specifically, the clamping ring 16 can be a hinge clamping method for easy installation.

[0053] This invention also provides a human-powered vehicle, including the gear shifter described above.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention 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 invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
