[0046] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Please refer to the following: Figures 1 to 9This embodiment provides an adjustment knob structure, a fixing component 100, and a gear adjustment knob 500. The fixing component 100 is provided with a first signal generating device, a second signal generating device, and a control component 400. The gear adjustment knob 500 is rotatably mounted on the fixing component 100. Multiple communicating windows 511 are spaced circumferentially on the gear adjustment knob 500. The first signal generating device includes a first infrared transmitter 210 and a first infrared receiver 220 separated by the gear adjustment knob 500. The second signal generating device includes... The second infrared transmitter 310 and the second infrared receiver 320 are separated by a 500-degree angle. By rotating the gear adjustment knob 500 forward, the connecting window 511 can be connected to the first signal generator to generate a first signal, and then to the second signal generator to generate a second signal; or by rotating the gear adjustment knob 500 in reverse, the connecting window 511 can be connected to the second signal generator to generate a second signal, and then to the first signal generator to generate a first signal. The control component 400 can control the increase or decrease of the gear position according to the order in which the first and second signals are generated. The fixed component 100 includes a power supply unit. The first signal generator is electrically connected to the control component 400, and the second signal generator is also electrically connected to the control component 400. The first and second signal generators are spaced apart. The first infrared transmitter 210 and the first infrared receiver 220 are correspondingly arranged, and the second infrared transmitter 310 and the second infrared receiver 320 are correspondingly arranged.

[0048] As can be seen, the adjustment knob structure in this embodiment, through the built-in first signal generating device and second signal generating device in the fixing component 100, in conjunction with the circumferential connecting window 511 of the gear adjustment knob 500, utilizes the sequence of triggering the first signal generating device and the second signal generating device by the connecting window 511 when rotated, allowing the control component 400 to accurately determine the direction of gear increase or decrease; this design eliminates the complex mechanical transmission or contact structure involved in traditional knobs, simplifies the overall structure, and at the same time, based on the triggering sequence judgment logic of the first signal and the second signal, avoids the recognition error that is easy to occur with a single signal, achieving the dual effect of structural simplification and precise gear adjustment.

[0049] Specifically, when the gear adjustment knob 500 is turned forward, the circumferentially arranged multi-connecting window 511 will rotate accordingly. The connecting window 511 first passes between the first infrared transmitter 210 and the first infrared receiver 220, so that the signal emitted by the first infrared transmitter 210 can be received by the first infrared receiver 220 to generate a first signal. As the rotation continues, the gear adjustment knob 500 will re-block the first infrared transmitter 210 and the first infrared receiver 220. Then, the connecting window 511 will pass between the second infrared transmitter 310 and the second infrared receiver 320, so that the signal emitted by the second infrared transmitter 310 can be received by the second infrared receiver 320 to generate a second signal. The control component 400 receives the first signal first and then the second signal to control the gear. When the gear adjustment knob 500 is turned upside down, the multi-connecting window 511 arranged circumferentially will rotate accordingly. The connecting window 511 will first pass between the second infrared transmitter 310 and the second infrared receiver 320 so that the signal emitted by the second infrared transmitter 310 can be received by the second infrared receiver 320 to generate a second signal. As the rotation continues, the gear adjustment knob 500 will block the second infrared transmitter 310 and the second infrared receiver 320 again. Then the connecting window 511 will pass between the first infrared transmitter 210 and the first infrared receiver 220 so that the signal emitted by the first infrared transmitter 210 can be received by the first infrared receiver 220 to generate a first signal. The control component 400 receives the second signal first and then the first signal to control the gear to be lowered.

[0050] In this embodiment, the fixing component 100 includes an adjusting column structure 111. The outer peripheral surface of the adjusting column structure 111 is provided with a plurality of slots 112 spaced apart along the circumferential direction. The gear adjustment knob 500 is rotatably sleeved on the adjusting column structure 111. The gear adjustment knob 500 includes a protruding structure that protrudes radially inward, so that when the gear adjustment knob 500 is rotated, the protruding structure can switch and be engaged in different slots 112.

[0051] The design incorporates multiple slots 112 spaced circumferentially on the outer peripheral surface of the adjusting column structure 111 of the fixed component 100, and a radially inwardly protruding structure on the gear adjustment knob 500. This allows the protruding structure to engage with different slots 112 when the gear adjustment knob 500 is rotated. This design, utilizing the cooperation between the protruding structure and the slots 112, provides clear tactile feedback to the user during gear adjustment, helping them clearly perceive gear shifting. It also positions the rotation of the gear adjustment knob 500, ensuring accuracy and stability, thus improving operational reliability and user experience. Each time the protruding structure rotates into an adjacent slot 112, it triggers a first signal and a second signal, causing the control component 400 to increase or decrease the gear position. This structure is simple and easy to manufacture.

[0052] Preferably, the gear adjustment knob 500 includes a knob body 510 and an elastic hoop. One side of the knob body 510 protrudes outward to form an annular protruding wall 512. The annular protruding wall 512 is rotatably sleeved on the adjustment column structure 111, and a through hole 513 is provided on the annular protruding wall 512. The elastic hoop is clamped on the annular protruding wall 512. At least part of the ring structure of the elastic hoop extends radially inward to form a protruding structure. The protruding structure can pass through the through hole 513 and be inserted into the slot 112.

[0053] The elastic hoop is a ring structure made of metal. The gear adjustment knob 500 is configured as a combination of the knob body 510 and the elastic hoop. The annular protruding wall 512 of the knob body 510 is fitted onto the adjustment column structure 111 and has a through hole 513. Part of the ring structure of the elastic hoop forms a protruding structure and passes through the through hole 513 and is engaged in the slot 112. This design utilizes the elastic characteristics of the elastic hoop to maintain a stable and moderate engagement force between the protruding structure and the slot 112. This ensures clear tactile feedback when shifting gears and avoids jamming or wear that may be caused by rigid connections. At the same time, the elastic structure facilitates installation and adjustment during assembly, improving the durability and ease of assembly of the overall structure. The structure is simple and easy to manufacture.

[0054] In this embodiment, the fixing component 100 includes a base structure 110 and a cover plate structure 120. The base structure 110 is provided with a first snap-fit ​​structure, and the cover plate structure 120 is provided with a second snap-fit ​​structure. The gear adjustment knob 500 has a clearance through hole, allowing the second snap-fit ​​structure to pass through the clearance through hole and engage with the first snap-fit ​​structure. The first snap-fit ​​structure is an elastic snap-fit ​​structure, and the second snap-fit ​​structure is a groove structure. The elastic snap-fit ​​structure can engage with the groove structure to complete the installation between the base structure 110 and the cover plate structure 120.

[0055] In this design, the fixing component 100 is a combination of a base structure 110 and a cover structure 120, with a first snap-fit ​​structure and a second snap-fit ​​structure respectively on both. A clearance through-hole is provided in the gear adjustment knob 500 to allow the second snap-fit ​​structure to pass through and engage with the first snap-fit ​​structure. This split-type snap-fit ​​design not only enables rapid assembly and disassembly of the fixing component 100, improving assembly efficiency and facilitating subsequent maintenance, but also provides a stable installation space for internal components such as the first signal generator, the second signal generator, and the control component 400 through the stable snap-fit ​​connection between the base and the cover, ensuring the reliability of component installation. Furthermore, the clearance through-hole cleverly avoids interference from the gear adjustment knob 500 on the snap-fit ​​structure assembly, balancing the rationality of the structural assembly with the normal realization of the gear adjustment function.

[0056] Preferably, the control component 400 includes a first circuit board 410 and a second circuit board 420. The first circuit board 410 is mounted on the cover structure 120, the first infrared emitter 210 and the second infrared emitter 310 are mounted on the first circuit board 410, the second circuit board 420 is mounted on the base structure 110, and the first infrared receiver 220 and the second infrared receiver 320 are mounted on the second circuit board 420.

[0057] The control component 400 is divided into a first circuit board 410 and a second circuit board 420. The first circuit board 410 is installed in the cover structure 120 and the second circuit board 420 is installed in the base structure 110. The first infrared transmitter 210 and the second infrared transmitter 310 are installed on the first circuit board 410, and the first infrared receiver 220 and the second infrared receiver 320 are installed on the second circuit board 420. This split-board installation design not only achieves the precise arrangement of the transmitting and receiving devices, ensuring the stability and accuracy of the transmission of the first and second signals, but also makes the circuit layout more reasonable, avoiding the complex wiring problem caused by the dense components on a single circuit board. At the same time, the split structure of the base and the cover facilitates the individual assembly, debugging and maintenance of each circuit board and the transmitting and receiving devices, improving the overall assembly efficiency and the convenience of later maintenance.

[0058] Preferably, the second circuit board 420 is provided with a switching button 130, which is electrically connected to the control component 400. The cover structure 120 is slidably engaged with the base structure 110 so that the switching button 130 can be triggered by pressing the cover structure 120 to switch the function of the control component 400.

[0059] Preferably, the cover structure 120 includes a lower cover 121 and an upper cover 122, a second snap-fit ​​structure is disposed on the lower cover 121, and the upper cover 122 is disposed on the lower cover 121 to form an installation cavity structure between the upper cover 122 and the lower cover 121.

[0060] In this design, the cover structure 120 is a combination of a lower cover 121 and an upper cover 122. The second snap-fit ​​structure is set on the lower cover 121, and the upper cover 122 covers the lower cover 121 to form an installation cavity structure. This split design allows the second snap-fit ​​structure of the lower cover 121 to easily cooperate with the first snap-fit ​​structure of the base structure 110, ensuring the reliability of the connection between the cover structure 120 and the base structure 110. On the other hand, the installation cavity structure enclosed by the upper cover 122 and the lower cover 121 can provide an independent and enclosed installation space for internal components such as the control component 400, effectively protecting the components and preventing external impurities or accidental collisions from affecting the operation of the components. At the same time, the split structure also makes it easy to assemble the components first onto the lower cover 121 and then cover the upper cover 122, improving the assembly convenience of the internal components of the cover structure 120 and taking into account both structural protection and assembly convenience.

[0061] Preferably, it also includes a display assembly 123, which is mounted in the mounting cavity structure, and the upper cover 122 is made of a light-transmitting material so that the light of the display assembly 123 can pass through for user interaction.

[0062] The design incorporates a mounting cavity structure formed by electrically connecting the display assembly 123 to the control assembly 400, with the upper cover 122 and lower cover 121 enclosing the cavity. The upper cover 122, preferably made of glass, is made of a light-transmitting material. This design provides a stable and enclosed mounting environment for the display assembly 123, effectively protecting it from external impurities and impacts, thus ensuring its operational stability and lifespan. Furthermore, the light-transmitting upper cover 122 allows light from the display assembly 123 to pass through smoothly for user interaction, enabling users to intuitively obtain information such as gear positions. This enriches the product's information display function, enhances the intuitiveness of operation and user experience. Integrating the display screen into the mounting cavity of the cover structure 120 also achieves a compact design, balancing functionality and structural rationality.

[0063] In this embodiment, a fixing seat structure 140 is provided on the outer peripheral side of the fixing component 100. The fixing seat structure 140 is provided with a mounting hole so that the fixing component 100 can be fixedly installed on the mounting surface by passing a screw through the mounting hole and screwing it into the mounting surface.

[0064] The mounting component 100 is installed by setting a mounting base structure 140 with mounting holes on the outer periphery of the mounting component 100. Screws are screwed into the mounting surface through the mounting holes to install the mounting component 100. This design allows the mounting component 100 to be stably assembled on the mounting surface, providing a reliable mounting base for components such as the gear adjustment knob 500, internal signal generator, and control component 400. This avoids structural shaking or displacement caused by insecure fixing during use, ensuring the stability of gear adjustment and the reliability of signal transmission. At the same time, the standardized mounting holes and screw fixing method are suitable for various installation scenarios, have good versatility and installation convenience, and are also easy to disassemble and maintain later, improving the installation applicability and reliability of the overall structure.

[0065] In this embodiment, the fixing component 100 is provided with a first connecting channel 150 and a second connecting channel 160 at vertical intervals. A first infrared transmitter 210 and a first infrared receiver 220 are disposed at both ends of the first connecting channel 150, and a second infrared transmitter 310 and a second infrared receiver 320 are disposed at both ends of the second connecting channel 160. The first infrared transmitter 210 and the second infrared transmitter 310 are infrared emitting devices, so that when the gear adjustment knob 500 is rotated, the connecting window 511 can connect the first connecting channel 150 and the second connecting channel 160.

[0066] In this design, by vertically spacing a first connecting channel 150 and a second connecting channel 160 within the fixed component 100, and employing an infrared transmitter as the transmitter, the channels are connected via the connecting window 511 of the gear adjustment knob 500. This design, through the vertically spaced arrangement of the two channels, makes the installation layout of the transmitting and receiving devices more reasonable, avoids signal interference, and ensures the independence and stability of the transmission of the first and second signals. The application of the infrared transmitter combines the accuracy and reliability of signal transmission, accurately identifying the connection status of the connecting window 511 to generate the corresponding signal. Furthermore, through the cooperation of the connecting window 511 and the two channels, the orderly generation of different signals can be precisely achieved, providing a stable signal source for the control component 400 to control the gear increase or decrease according to the signal generation sequence, thereby improving the accuracy of gear adjustment and the overall structural reliability.

[0067] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0068] The adjustment knob structure of this utility model incorporates a first signal generator and a second signal generator within the fixed component 100. These, along with the circumferential connecting window 511 of the gear adjustment knob 500, utilize the sequential triggering of the first and second signal generators by the connecting window 511 during rotation. This allows the control component 400 to accurately determine the direction of gear increase or decrease. This design eliminates the complex mechanical transmission or contact structure involved in traditional knobs, simplifying the overall structure. Furthermore, based on the triggering sequence of the first and second signals, it avoids the identification errors that can easily occur with a single signal, achieving the dual effects of structural simplification and precise gear adjustment.
