Description

Technical Field

[0001] This utility model relates to the field of gear transmission technology, specifically to a gear transmission operating device and a riding device. Background Technology

[0002] As a racing tool, road bikes require not only basic brakes but also an essential gear control mechanism on the handlebars. The primary gear control mechanism is the electronic derailleur, which is widely used in bicycles. Users can shift gears by pressing different buttons on the electronic derailleur.

[0003] Currently, the two buttons on electronic derailleurs typically activate the shifting function by rotating them to actuate contacts in a control mechanism. These two buttons are rotatably connected to the same shaft, making installation and removal cumbersome and prone to interference. Furthermore, the two buttons have significantly different tactile feedback, resulting in a poor user experience. In addition, the battery in electronic derailleurs requires frequent removal and replacement, and its placement must be ergonomically sound and easy to remove. Summary of the Invention

[0004] The purpose of this invention is to provide a speed-changing operating device to at least partially solve the problems mentioned in the background art.

[0005] Therefore, this utility model provides a speed-changing operating device, including: a mounting base having a first mounting cavity and a second mounting cavity inside; a control module installed in the first mounting cavity; a battery installed in the second mounting cavity, the battery being used to power the control module; and a first button rotatably mounted on the mounting base via a first cantilever. The second button is rotatably mounted on the mounting base via the second cantilever; the control module is activated by the first button and / or the second button, causing the control module to issue a control command to change speed; the axial direction of the first cantilever and the axial direction of the second cantilever are parallel and do not coincide.

[0006] Preferably, the mounting base is provided with a first rotating groove and a second rotating groove, the first rotating groove and the second rotating groove are parallel to each other and do not coincide; the first cantilever is rotatably fitted in the first rotating groove, and the second cantilever is rotatably fitted in the second rotating groove.

[0007] Preferably, the first rotating groove is provided with a first limiting part, which is used to limit the axial movement of the first cantilever; the second rotating groove is provided with a second limiting part, which is used to limit the axial movement of the second cantilever.

[0008] Preferably, the control module includes a PCBA board, the PCBA board being connected to a positive electrode spring and a negative electrode spring; the second mounting cavity is provided with a first through hole and a second through hole, the positive electrode spring passing through the first through hole and connected to the positive electrode of the battery, and the negative electrode spring passing through the second through hole and connected to the negative electrode of the battery.

[0009] Preferably, the side wall of the mounting base is connected to a sealing cover, and the battery can be installed and / or removed by opening and closing the cover.

[0010] Preferably, the inner side of the sealing cover is provided with a clearance cavity that is opposite to the second mounting cavity, and the edge of the battery extends out of the second mounting cavity and fits into the clearance cavity.

[0011] Preferably, both the first button and the second button have contact points on their inner surfaces. When the first button and / or the second button are rotated until the contact points abut against the control module, the control module issues a control command to change speed.

[0012] Preferably, the control module is provided with a trigger part corresponding to the contact point, the trigger part includes a guide post, and the guide post abuts against the soft rubber mold on the PCBA board.

[0013] Preferably, the guide post is provided with an elastic reset member, which is used to reset after the first button and / or the second button is rotated.

[0014] This utility model also provides a riding device, including a frame, a handlebar on the frame, a brake lever on the handlebar, and the aforementioned gear shifting device on the brake lever.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are: This application provides a sealing cover on the side wall of the mounting base, which facilitates the installation and removal of the battery and provides space for battery installation, making the transmission operation device of this application compact and centralized, and reducing the overall volume of the transmission operation device.

[0016] The first button is rotatably mounted on the mounting base via the first cantilever, and the second button is rotatably mounted on the mounting base via the second cantilever. The axes of the first and second cantilever are parallel and do not overlap, which allows for convenient and quick installation of the first and second buttons, and ensures that the installation and removal processes of the first and second buttons do not interfere with each other, and that the rotation of the first and second buttons does not interfere with each other.

[0017] Furthermore, to ensure that the actuation force of the first and second buttons is as similar as possible, and due to the limitation of their pressing positions, the lengths of the first and second cantilever arms need to be adjusted to compensate for the difference in button pressing positions, thereby changing the button pivot point. The distance between the axes of the first and second cantilever arms is less than 1mm, which allows the lever ratio of the first and second buttons to be nearly identical, and the pressing force and feel of the first and second buttons to be similar, which is beneficial to improving the rider's operating experience.

[0018] The first button and the second button of this application are rotatably connected to the first rotating shaft and the second rotating shaft, respectively. The first rotating shaft is arranged parallel to the bottom of the second rotating shaft, and the first rotating shaft and the second rotating shaft are offset, that is, the right end of the first rotating shaft protrudes beyond the right end of the second rotating shaft, and the left end of the second rotating shaft protrudes beyond the left end of the first rotating shaft. With the above arrangement, the first button and the second button can be installed conveniently and quickly, and the installation and removal processes of the first button and the second button do not interfere with each other.

[0019] Furthermore, since the first pivot is located below the second pivot, the pressing position of the first button is lower than that of the second button. This reduces the difference in lever length between the first and second buttons, making the pressing force and feel of the first and second buttons similar, which helps improve the rider's operating experience.

[0020] Other features and advantages of this utility model will become clearer after reading the detailed embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] This application provides a gear shifting device that can be applied to the frame of a cycling device.

[0024] like Figures 1-11 As shown, the gear shifting device of this application includes a mounting base 100, a control module 200, a battery 300, a first button 400, and a second button 500. The gear shifting device of this application is lightweight and easy to operate; by installing the battery 300 within the mounting base 100, the gear shifting device of this application can achieve a compact and integrated structure. Specifically: The gear shifting device of this application is mounted on the brake lever 600 of the handlebars of the cycling equipment via the mounting base 100. It can be disassembled and reassembled as a whole, which is convenient for maintenance. The rider has a smaller span when controlling the brake lever 600 and the gear shifting device, which improves the ease of use. Moreover, the first button 400 is overlapped on the outside of the second button 500, which is compact and does not require a lot of finger movement. It is convenient and comfortable to operate, and the rider is less likely to be distracted, thus better ensuring cycling safety.

[0025] Mounting base 100 can be a one-piece machined metal or plastic part, and no specific restrictions are made here.

[0026] One end of the mounting base 100 is mounted on the brake lever 10 of the vehicle body by screws. The mounting base 100 has a first mounting cavity and a second mounting cavity inside. The first mounting cavity is used to install the control module 200, and the second mounting cavity is used to install the battery 300.

[0027] The first mounting cavity is adapted to the shape and structure of the control module 200, and the second mounting cavity is adapted to the shape and structure of the battery 300.

[0028] The mounting base 100 has an opening 101 on its side wall that communicates with the second mounting cavity. A sealing cover 301 is connected to the opening 101. The battery 300 can be installed and removed by opening and closing the sealing cover 301.

[0029] One end of the sealing cover 301 is rotatably connected to the side wall of the mounting base 100 via a pivot 302, allowing the sealing cover 301 to rotate and thus open and close. The other end of the sealing cover 301 is fixedly connected to the side wall of the mounting base 100 via screws 303, ensuring a secure and reliable connection and preventing the sealing cover 301 from falling off due to bumps and vibrations during riding.

[0030] Remove screw 303 by rotating it, then rotate the sealing cover 301 to open it. Rotate the sealing cover 301 to close it (the sealing cover 301 covers the opening 101), and then lock the sealing cover 301 onto the mounting base 100 with screw 303 to close it.

[0031] The inner side of the sealing cover 301 is provided with a connecting cavity 304. When the sealing cover 301 is closed, the connecting cavity 304 corresponds to and is connected to the second mounting cavity. When the sealing cover 301 is closed, the edge of the battery 300 extends into the connecting cavity 304, and the battery 300 can fit in the space enclosed by the connecting cavity 304 and the second mounting cavity.

[0032] By providing a sealing cover plate 301 on the side wall of the mounting base 100, this application facilitates the installation and removal of the battery 300 and provides installation space for the battery 300, making the transmission operation device of this application compact and centralized, and reducing the overall volume of the transmission operation device.

[0033] The inner side of the sealing cover 301 is also provided with a groove 305, which surrounds the opening of the connecting cavity 304, and a sealing ring 306 is provided in the groove 305. When the sealing cover 301 is closed, the sealing ring 306 just abuts against the edge of the opening of the mounting base 100, which can realize the sealed installation of the battery 300.

[0034] The control module 200 includes a PCBA board 201, with a positive electrode spring 202 and a negative electrode spring 203 located below the PCBA board 201. When the control module 200 is installed in the first mounting cavity and the battery 300 is installed in the second mounting cavity, the positive electrode spring 202 can be connected to the positive terminal of the battery 300, and the negative electrode spring 203 can be connected to the negative terminal of the battery 300, thereby enabling the battery 300 to supply power to the control module 200.

[0035] The second mounting cavity has a first through hole 102 and a second through hole 103 on its cavity wall, both of which are connected to the first mounting cavity. When the control module 200 is installed in the first mounting cavity and the battery 300 is installed in the second mounting cavity, the positive electrode spring 201 can pass through the first through hole 102 and be connected to the positive electrode of the battery 300, and the negative electrode spring 203 can pass through the second through hole 103 and be connected to the negative electrode of the battery 300.

[0036] The shapes of the positive electrode spring 202 and the negative electrode spring 203 can be seen in the attached diagram. This structure is easy to install and has a large visible range for the springs.

[0037] The control module 200 also includes a button cover 204, which covers the PCBA board 201. Two guide posts 205 are installed on the button cover 204. The guide posts 205 pass through the button cover 204 and abut against the soft rubber mold on the PCBA board 201.

[0038] The first button 400 has a first trigger part 401 corresponding to one guide post 205, and the second button 500 has a second trigger part 501 corresponding to another guide post 205. When the user needs to change gears while riding, they press the first button 400 and / or the second button 500. After pressing the first button 400, the first button 400 rotates, and the first trigger part 401 abuts against the guide post 205, thus triggering the corresponding gear shift mode. Similarly, after pressing the second button 500, the second button 500 rotates, and the second trigger part 501 abuts against the other guide post 205, thus triggering the corresponding gear shift mode.

[0039] A spring-loaded reset element 206 is fitted onto the guide post 205. The spring-loaded reset element 206 can be a spring, torsion spring, or sheet spring, etc., and no specific limitation is made here. The spring-loaded reset element 206 can extend the travel of the button as perceived by the user, which has the advantages of good operation feel, ease of implementation, and less chance of accidental touch.

[0040] The first trigger part 401 is a cross-shaped column structure protruding from the first button 400, and the end of the first trigger part 401 directly abuts against the elastic reset member 206.

[0041] The second trigger part 501 is a cross-shaped column structure protruding from the second button 500, and the end of the first trigger part 401 directly abuts against the elastic reset member 206.

[0042] The first button 400 can be a one-piece metal or plastic part, and no specific restrictions are made here.

[0043] The first button 400 is provided with a first cantilever 402 extending outward, and the end of the first cantilever 402 away from the first button 400 has an arc-shaped cross section.

[0044] The mounting base 100 is provided with a first rotating groove 104, and the end of the first cantilever 402 is rotatably fitted in the first rotating groove 104 to realize the rotation of the first button 400.

[0045] The first cantilever 402 is provided with a first mating hole 403, and the first rotating groove 104 is provided with a protruding first limiting part 105, which fits into the first mating hole 403. Through the cooperation of the first limiting part 105 and the first mating hole 403, the first button 400 can be limited, which can effectively prevent the first button 400 from moving axially and ensure that the first button 400 can rotate effectively.

[0046] The second button 500 can be a one-piece metal or plastic part, and there are no specific restrictions here.

[0047] The second button 500 is provided with an extended second cantilever 502, and the end of the second cantilever 502 away from the second button 500 has an arc-shaped cross section.

[0048] The mounting base 100 is provided with a second rotating groove 106, and the second cantilever 502 is rotatably engaged in the second rotating groove 106 to realize the rotation of the second button 500.

[0049] The second connecting arm 502 is provided with a second mating hole 503, and the second rotating groove 106 is provided with a protruding second limiting part 107, which fits into the second mating hole 503. Through the cooperation of the second limiting part 107 and the second mating hole 503, the second button 500 can be limited, which can effectively prevent the second button 500 from moving axially and ensure that the second button 500 can rotate effectively.

[0050] In some embodiments of this application, there are two first cantilever arms 402, each disposed at one end of the first button 400, corresponding to two first rotating grooves 104. There are also two second cantilever arms 502, each disposed at one end of the second button 500, corresponding to two second rotating grooves 106. There are two first rotating grooves 104 and two second rotating grooves 106; one first rotating groove 104 and one second rotating groove 106 are adjacent and disposed at one end of the mounting base 100, while the other first rotating groove 104 and the other second rotating groove 106 are adjacent and disposed at the other end of the mounting base 100. The axial directions of the first cantilever arms 402 and the second cantilever arms 502 are parallel and do not coincide, and the axial directions of the corresponding first rotating grooves 104 and the second rotating grooves 106 are parallel and do not coincide. With the above settings, the first button 400 and the second button 500 can be installed conveniently and quickly, and the installation and removal processes of the first button 400 and the second button 500 can be carried out without interference, and the rotation of the first button 400 and the second button 500 can be carried out without interference.

[0051] Furthermore, to ensure that the actuation force of the first button 400 and the second button 500 is as similar as possible, and due to the limitation of their pressing positions, the lengths of the first cantilever 402 and the second cantilever 502 need to be adjusted to compensate for the difference in button pressing positions, thereby changing the button pivot point position. In this application, the axes of the first cantilever 402 and the second cantilever 502 are parallel but not coincident, and the distance between the axis of the first cantilever 402 and the axis of the second cantilever 502 is less than 1mm (preferably 0.1-0.5mm). This allows the lever ratio of the first button 400 and the second button 500 to be nearly identical, and the pressing force and pressing feel of the first button 400 and the second button 500 to be similar, which is beneficial to improving the rider's operating experience.

[0052] The outer surface of the first button 400 protrudes from the outer surface of the second button 500, so that the rider can accurately find the button by the protruding touch, which makes the operation feel better and prevents the second button 500 from being accidentally pressed when pressing the first button 400.

[0053] This application also provides a riding device, including a frame, a handlebar mounted on the frame, a brake lever 600 mounted on the handlebar, a gear shifting device mounted on the brake lever 600, and the gear shifting device being integrally mounted on the brake lever 600.

[0054] The installation methods between the mounting bracket 100 and the brake lever 600 include, but are not limited to, plug-in connection, snap-fit ​​connection, bolt connection, etc., which will not be specifically described here.

[0055] The gear shifting device can be located on the front, rear, upper, lower or other sides of the brake lever, and this application does not impose any restrictions on this.

[0056] The specific structure, principle, and effect of the gear shifting device of the cycling equipment can be found in the gear shifting device described above in this manual, and will not be repeated here.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
