Description

Technical Field

[0001] This utility model relates to the field of mechanical shift controller technology, and in particular to a mechanical shift controller that facilitates shifting operations. Background Technology

[0002] Bicycles, as a green and convenient mode of transportation, have a large user base worldwide. As an important component of bicycles, the mechanical gear shifter allows riders to flexibly adjust gears according to different road conditions (such as uphill, downhill, and flat roads) and their own physical condition, thereby achieving a more comfortable riding experience and higher riding efficiency.

[0003] Existing mechanical shift controllers for bicycles primarily rely on mechanical structures to achieve gear shifting, typically using a combination of a mechanical pointer and a fixed dial for gear indication. In daylight or well-lit environments, riders can determine the current gear by observing the pointer's position on the dial. However, this method has significant limitations. When riding at night, in tunnels, or basements, the lack of sufficient light makes it difficult to clearly see the pointer and dial, leading to inaccurate gear selection. This not only affects riding smoothness but may also prevent timely gear changes, increasing the risk of accidents. For example, when riding uphill at night, inaccurate gear selection can lead to excessive effort due to delayed shifting, increased energy expenditure, and even falls. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mechanical shift controller that facilitates shifting operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mechanical gear shift controller for easy gear shifting includes a housing, a gear adjustment mechanism, and a gear indicator for indicating gear changes, the gear indicator being disposed within a receiving space defined by the housing; and further includes:

[0007] Batteries; and

[0008] A lighting fixture, which is electrically connected to the battery via a mechanical switch;

[0009] The gear position indicator is positioned within the illumination range of the light source, and the housing has a transparent window for viewing the gear position indicator, so that the user can perform gear shifting operations in poor lighting conditions.

[0010] Furthermore, the mechanical shift controller is configured to control the gear shift line via a mechanical structure to achieve the gear change.

[0011] Furthermore, the gear indicator has an indicator segment that changes position along a preset path to indicate a gear change, and the indicator segment is located within the illumination range of the lighting lamp.

[0012] Furthermore, the light source is directed toward a preset path along which the position of the indicator segment changes, in order to provide illumination.

[0013] Furthermore, the transparent window is configured in accordance with the lighting lamp and the indicator segment to facilitate the user's observation of gear changes.

[0014] Furthermore, a waterproof space is formed inside the housing to prevent moisture from entering the housing and corroding the lighting circuit. A buzzer electrically connected to the battery is also disposed in the waterproof space.

[0015] Furthermore, the battery is a button battery suitable for installation in the waterproof space.

[0016] Furthermore, the housing includes an upper housing and a lower housing, the transparent window is disposed on the upper housing, and the lower housing is provided with a mounting base suitable for mounting the lighting lamp.

[0017] Furthermore, the gear adjustment mechanism includes an upper fixed plate, a lower fixed plate, and a winding reel. The winding reel is rotatably fixed between the upper and lower fixed plates, and the gear adjustment mechanism is configured to change gears by controlling the rotation of the winding reel.

[0018] Furthermore, the reel is provided with a positioning groove, and one end of the gear indicator is disposed in the positioning groove so as to rotate with the reel to indicate the gear change. The gear adjustment mechanism also includes a push rod and a release rod for controlling the rotation direction of the reel.

[0019] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0020] 1. This invention overcomes the limitations of traditional mechanical shift controllers that rely on mechanical feedback by deeply integrating an electrical indicator with a mechanical transmission structure. The mechanical linkage between the gear position indicator and the winding reel is transformed into a visual optical indicator system through the configuration of electrical components such as a light, battery, and transparent window. This electrification of the mechanical structure upgrades the gear position status from "feel judgment" to "direct visual reading"—when shifting gears using the gear adjustment mechanism, the mechanical rotation of the gear position indicator is synchronously converted into a positional change in front of the transparent window. Combined with the electrical illumination function of the light, gear position information can be transmitted to the user through an optical path even inside the mechanical structure. Because of the electrical indication function, this invention's mechanical shift controller is no longer limited to daytime or well-lit environments but can be widely applied in various scenarios, which not only improves ease of use but also greatly enhances safety.

[0021] 2. The housing of this utility model features a waterproof component design, giving the entire mechanical shift controller excellent waterproof performance. This design effectively prevents moisture, dust, and other impurities from entering the interior, protecting electrical and mechanical components from damage and extending the equipment's service life. Whether in a vehicle driving in the rain or in a humid industrial environment, this mechanical shift controller can maintain normal operation, greatly improving the equipment's environmental adaptability and reliability. At the same time, the waterproof design also reduces maintenance costs and frequency, resulting in good economic efficiency.

[0022] 3. The electrical indicator device of this utility model uses a button battery as its power source, which has the advantages of small size, convenient installation, and simple replacement. The capacity of the button battery is sufficient to meet the long-term working needs of the lighting fixture, and battery replacement requires no special tools, making it convenient for users to maintain. In addition, the circuit connection of the electrical system of this application is simple and reliable. Through the reasonable arrangement of conductive sheets and wires, stable current transmission is ensured, improving the reliability of the electrical system. Attached Figure Description

[0038] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0039] Please see Figure 1This utility model discloses a mechanical shift controller for easy gear shifting. The mechanical shift controller of this application includes a housing 100, a gear adjustment mechanism 200, and a gear indicator 320 for indicating gear changes. The gear indicator 320 is disposed in a receiving space 300 defined by the housing. The housing 100 serves as a protective housing for the entire transmission, playing a crucial role in supporting the internal structure and protecting against external environmental interference. The gear adjustment mechanism 200 is responsible for realizing the core function of mechanical gear shifting, flexibly adjusting gear changes through a precise internal mechanical structure. The indicator 320 is used to accurately indicate the current gear change, ensuring that the user can clearly understand the gear shifting status even at night or in low light conditions. It should be noted that the mechanical shift controller in this application is configured as a transmission that controls the gear train through a mechanical structure to achieve gear changes. This differs from an electromechanical transmission that controls the motor-driven gear shifting mechanism through electronic signals, as the gear changes in this transmission are entirely achieved through a mechanical structure.

[0040] Please see Figures 2-6 The housing 100 is specifically composed of two parts: an upper housing 110 and a lower housing 120. The upper housing 110 and the lower housing 120 form a receiving space 300. A transparent window 340 is disposed on the upper housing 110. The function of the transparent window 340 is to allow the user to directly observe the gear changes indicated by the gear position indicator 320 inside the transmission. To more accurately indicate gear changes, the transparent window 340 is provided with digital indicators 341, which are rationally divided according to the number and interval of gear changes. For example, if the transmission has 7 gear changes, then the transparent window 340 will have 7 digital indicators 341, corresponding to gears 1-7 respectively. The user can clearly understand the current gear change simply by observing the position of the gear position indicator 320 relative to the digital indicators 341.

[0041] Please see Figures 3-6In this embodiment, battery 310 is used to provide electrical energy. In this application, battery 310 is a button cell battery. Button cells have advantages such as small size, moderate capacity, and easy installation, making them very suitable for use in the mechanical shift controller of this application. In this embodiment, the battery is a 3-24V DC power supply with positive and negative terminals. Battery 310 is mounted on the top of upper mounting plate 210. Gear position indicator 320 is a key component for indicating gear changes in gear adjustment mechanism 200. The other end of gear position indicator 320 points to the digital indicator 341 on transparent window 340. By observing the position of the digital indicator 341 indicated by gear position indicator 320, the user can understand the current gear change. The function of lamp 330 is to emit light, providing illumination for gear position indicator 320, making it clearly visible even in low-light environments. Lamp 330 uses a suitable light-emitting element, such as an LED lamp, which has advantages such as high luminous efficiency, long lifespan, and low energy consumption. The lamp 330 is electrically connected to the battery 310 via a mechanical switch 350. A mounting base 121 is disposed on the lower housing 120, and the lamp 330 is mounted on the mounting base 121. In this embodiment, the gear indicator 320 has an indicator segment that changes position along a preset path to indicate gear changes. This indicator segment is located within the illumination range of the lamp 330, and the light emission direction of the lamp 330 is directed towards the preset path along which the indicator segment changes position, thus providing illumination. Furthermore, a transparent window 340 is correspondingly positioned to the lamp 330 and the indicator segment to facilitate user observation of gear changes. Its position is carefully designed to ensure accurate illumination of the gear indicator 320. The lamp 330 is electrically connected to the battery 310, and its on / off state is controlled by the mechanical switch 350. The transparent window 340 serves as a window for the user to observe gear changes. The digital indicator 341 on the window accurately indicates gear changes, and its scale is precisely divided according to the number and intervals of gear changes in the transmission. The mechanical switch 350 controls the on / off state of the electrical indicator 300. In this application, the mechanical switch 350 is a toggle switch. The toggle switch is electrically connected to the battery 310 via a conductive piece 360. One terminal of the switch is connected to the conductive piece 360 ​​and then to one pole of the button battery. One wire is soldered to the other terminal of the switch and connected to the indicator element, allowing the switch to control the on / off state of this circuit. The other wire is also connected to the indicator element and then to a conductive terminal, which is connected to the other pole of the battery (the indicator element also has positive and negative poles). When the user flips the mechanical switch 350, the circuit is turned on, the lamp 330 lights up, and the gear indicator 320 is clearly visible under the light; when the mechanical switch 350 is flipped again, the circuit is turned off, the lamp 330 is turned off, thereby realizing the control of the electric indicator 300.In this embodiment, the housing 100 adopts a waterproof structural design, forming a waterproof space inside to prevent moisture from entering the housing and corroding the lighting circuit. This waterproof space effectively prevents moisture from entering the transmission, avoiding damage to internal electronic components and mechanical structures due to moisture, and significantly improving the reliability and service life of the transmission.

[0042] It should be noted that, in order to achieve the electrification of the mechanical structure of this application, a buzzer or other electronic control device electrically connected to the battery 310 may also be provided, as long as the size is sufficient to be installed in the housing 100, which will not be elaborated on here.

[0043] Please see Figure 7 , Figure 8 The gear shifting mechanism 200 is the core component for realizing the mechanical gear shifting function. It mainly includes an upper fixed plate 210, a lower fixed plate 220, a reel 230, a ratchet assembly 240, a push rod 250, and a release rod 260. The upper fixed plate 210 and the lower fixed plate 220 are fixed together by bolts to form a stable frame structure for supporting and fixing other gear shifting components. The reel 230 is rotatably fixed between the upper fixed plate 210 and the lower fixed plate 220. A ratchet assembly 240, which rotates together with the reel 230, is fixed on the reel 230 and is fixed between the upper fixed plate 210 and the lower fixed plate 220. In this embodiment, the ratchet assembly 240 mainly consists of a ratchet and a pawl. The ratchet is fixedly connected to the reel, and the pawl is fixed between the upper and lower fixed plates via a pawl shaft. When the reel rotates, the ratchet rotates accordingly, and the pawl acts as a one-way lock to prevent the reel from reversing on its own without external force, thus ensuring the stability of gear changes. The method of controlling the reel rotation via the ratchet assembly in this application is the same as in the prior art, and will not be elaborated further here. A positioning groove 231 is provided on the reel 230 for mounting the gear indicator 320. One end of the gear indicator 320 is disposed within the positioning groove 231. When the reel 230 rotates, the gear indicator 320 rotates along with the reel 230, thus indicating the current gear change in real time. The push rod 250 and the release rod 260 are both connected to the ratchet assembly 240 to control the rotation direction of the reel 230. The push rod 250 pushes the ratchet assembly 240, causing the reel 230 to rotate in one direction, thereby achieving the first gear change. The release lever 260 releases the locked state of the ratchet assembly 240, allowing the reel 230 to rotate in another direction, thereby achieving a second gear shift. The push lever 250 and release lever 260 are typically designed using the lever principle, and their operation enables the gear shifting described in this application.

[0044] When a user needs to know the current gear position in a dimly lit environment, they first turn on the mechanical switch 350 to power on the lamp 330, which illuminates the gear position indicator 320. Since the gear position indicator 320 rotates with the reel 230, its position reflects the current gear position. The user can accurately understand the gear position by observing the position of the digital indicator 341 indicated by the gear position indicator 320 through the transparent window 340.

[0045] When changing gears, the user simply operates the gear adjustment mechanism 200 to move the push rod 250 or the release rod 260. The pawl 242 engages with the ratchet 241, providing a one-way locking function to ensure the stability of gear changes. When the cable reel 230 rotates to the desired gear, the pawl 242 re-locks the ratchet 241, positioning the cable reel 230 and maintaining the current gear position. At this time, the gear indicator 320 also stops at the position corresponding to the gear change, which the user can clearly observe through the transparent window 340.

[0046] When the power indicator function is no longer needed, the user can simply toggle the mechanical switch 350 to disconnect the circuit and turn off the light 330, thereby saving energy.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
