After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.

[0063] Please refer to Figure 1-3 This utility model provides an automatic lifting knob device. The device has a compact structure and ingenious design, and is mainly composed of several key parts, including a knob assembly 1, a guide bracket 2, an automatic lifting assembly 3, and a base 4.

[0064] Specifically, the knob assembly 1 is disposed on one end face of the guide bracket 2. This design enables the knob assembly 1 and the guide bracket 2 to form a stable connection, laying the foundation for subsequent coordinated movement.

[0065] The automatic lifting component 3 is disposed on the opposite end face of the guide bracket 2, and is located between the guide bracket 2 and the base 4. This layout makes full use of the space between the guide bracket 2 and the base 4, enabling the automatic lifting component 3 to perform its due driving function.

[0066] The automatic lifting assembly 3 plays a core driving role in the entire device. It possesses the necessary driving force to drive the guide bracket 2 to move up and down relative to the base 4. Since the knob assembly 1 is closely connected to the guide bracket 2, when the guide bracket 2 moves up and down under the action of the automatic lifting assembly 3, the knob assembly 1 will also move up and down synchronously. Through this coordinated movement mechanism, the knob assembly 1 can achieve flexible and smooth switching between the extended and retracted states.

[0067] It is understood that the automatic lifting knob device proposed in this embodiment of the invention drives the guide bracket 2 to move up and down relative to the base 4 through the automatic lifting component 3, thereby enabling the knob component 1 to flexibly switch between the extended and retracted states. This design concept has significant advantages. In practical applications, this design can fully consider the specific needs of users and diverse usage scenarios, dynamically adjusting the position of the knob component 1.

[0068] For example, when a user needs to operate the device, the knob assembly 1 can automatically extend to the appropriate position, allowing the user to quickly and accurately adjust various parameters of the device, greatly improving operational efficiency and convenience. When no operation is needed or the device is idle, the knob assembly 1 can automatically retract. This function not only effectively avoids accidental operation caused by accidental touches, ensuring the safety and stability of the device, but also saves space, making the device's appearance simpler and more aesthetically pleasing, and enhancing the overall quality of the device.

[0069] This automatic lifting knob device with dynamic adjustment not only successfully solves the inconveniences of traditional fixed knobs, such as the inability to flexibly adjust their position according to the usage scenario, but also overcomes the drawback of traditional knobs affecting the aesthetics of the equipment. More importantly, it provides greater freedom and flexibility in the overall design of the equipment, enabling it to better adapt to various complex and changing usage scenarios and the personalized needs of different users. This significantly improves the practicality and aesthetics of the equipment, and has broad market application prospects and significant practical value.

[0070] Please refer to Figure 4-6 In one embodiment of this example, the automatic lifting component 3 serves as the core power and transmission module for the entire automatic lifting knob device to achieve dynamic adjustment of the position of the knob component 1. It has an ingenious structural design and complete functions, and is mainly composed of three key components: a drive motor 301, a transmission mechanism 302, and a lifting screw 303.

[0071] Specifically, the drive motor 301 is securely mounted on the guide bracket 2. As a power source, the stability and accuracy of the drive motor 301's performance are crucial for the normal operation of the entire automatic lifting assembly 3. A tight transmission connection is established between the output shaft of the drive motor 301 and the transmission mechanism 302. The transmission mechanism 302 plays a key role in power transmission and conversion, transmitting the rotational power of the drive motor 301's output shaft to subsequent components in a suitable manner. It can also adjust the power according to actual needs, such as changing parameters like speed and torque, to ensure the smoothness and efficiency of the entire transmission process.

[0072] The lifting screw 303 is connected to the base 4 via a threaded connection. This threaded connection offers advantages such as good self-locking and high transmission accuracy, ensuring the stability and accuracy of the guide bracket 2 during lifting. Through this threaded connection, the lifting screw 303 can generate axial displacement when rotating, thereby driving the connected components to perform lifting movements.

[0073] When the drive motor 301 starts, its output shaft begins to rotate, transmitting rotational power to the lifting screw 303 via the transmission mechanism 302. Under the action of the transmission mechanism 302, the lifting screw 303 begins to rotate. Because there is a threaded connection between the lifting screw 303 and the base 4, when the lifting screw 303 rotates, it displaces along its own axial direction, allowing the guide bracket 2 to move up and down relative to the base 4 as the lifting screw 303 moves axially. Through this ingenious mechanical transmission structure, precise lifting and lowering of the guide bracket 2 is achieved, thereby enabling the knob assembly 1 to flexibly switch between extended and retracted states, meeting the positional requirements of the knob assembly 1 in different usage scenarios, and improving the flexibility of the device and the user experience.

[0074] Please refer to this again. Figure 4-5 In one embodiment of this invention, the base 4, as a key component in the entire automatic lifting knob device, plays a crucial role in supporting and positioning the device. Its structural design is essential for the stable operation and functional realization of the device. An internal thread 5 is carefully formed on the base 4 to engage with the lifting screw 303.

[0075] The internal thread 5 was not created arbitrarily, but rather through rigorous design considerations. Its specifications, such as pitch and thread profile, are matched with the external thread of the lifting screw 303 to ensure a tight and precise threaded fit. This threaded fit offers several advantages. Firstly, it provides reliable connection and support, allowing the lifting screw 303 to move stably along a predetermined axial direction during rotation, thereby driving the guide bracket 2 to lift and lower. Secondly, the threaded fit also possesses a certain degree of self-locking performance, maintaining the current position of the guide bracket 2 and the knob assembly 1 after the drive motor 301 stops working, preventing accidental movement due to external forces, and ensuring the stability and safety of the device.

[0076] In actual operation, when the drive motor 301 starts and drives the lifting screw 303 to rotate, the external thread on the lifting screw 303 meshes with the internal thread 5 on the base 4, generating axial thrust or pull, so that the lifting screw 303 rises or falls along its axial direction while rotating, and the guide bracket 2 will move up and down synchronously, thereby driving the knob assembly 1 to switch flexibly between the extended state and the retracted state.

[0077] In one embodiment of this invention, the length of the internal thread 5 is set to be no less than the stroke of the guide bracket 2 during its lifting movement.

[0078] This design is not arbitrary, but rather the result of a comprehensive consideration of various factors, including the overall functional requirements, structural stability, and operational reliability of the device. From a functional perspective, the lifting stroke of the guide bracket 2 is a key factor determining the extension and retraction range of the knob assembly 1. The length of the internal thread 5 must be sufficient to meet this stroke requirement to ensure that the guide bracket 2 maintains a stable and effective threaded engagement with the lifting screw 303 throughout the lifting process. If the length of the internal thread 5 is too short, the threaded engagement may fail when the guide bracket 2 reaches the end of its stroke, causing the guide bracket 2 to be unable to continue lifting stably. This, in turn, affects the normal extension and retraction of the knob assembly 1, reducing the overall performance of the device.

[0079] From the perspective of structural stability, a sufficiently long internal thread 5 can provide more adequate support and guidance for the lifting screw 303. During the lifting movement of the guide bracket 2, the lifting screw 303 will be subjected to various forces and torques from the guide bracket 2. The internal thread 5, through its tight fit with the lifting screw 303, can effectively disperse and bear these forces and torques, reduce the bending deformation and vibration of the lifting screw 303, and ensure the structural stability of the device.

[0080] From the perspective of operational reliability, the length of the internal thread 5, which is not less than the lifting stroke of the guide bracket 2, can reduce the risk of device failure due to problems such as thread wear and loosening. During long-term use, the threaded parts will inevitably experience a certain degree of wear. A sufficiently long internal thread 5 can provide a certain wear allowance, ensuring effective engagement between the lifting screw 303 and the internal thread 5 even if some wear occurs, thus ensuring stable and reliable operation of the device over a longer period of time.

[0081] Therefore, setting the length of the internal thread 5 to be no less than the stroke of the guide bracket 2 is an important technical measure to ensure the normal, stable and reliable operation of the automatic lifting knob device.

[0082] Please refer to this again. Figure 4-5 and in conjunction with references Figure 7 In one embodiment of this invention, the base 4 is provided with a guide groove 6;

[0083] The guide groove 6 was designed for precise control of the movement trajectory of the guide bracket 2. Its shape, size, and layout on the base 4 were all based on rigorous engineering design and mechanical analysis. The cross-sectional shape of the guide groove 6 is adapted to the shape of the insertion part of the guide bracket 2 to ensure a tight and stable fit between the two, while minimizing friction and wear during movement.

[0084] The guide bracket 2 is precisely inserted into the guide groove 6. This insertion-type structural design establishes a clear relative positional relationship between the guide bracket 2 and the base 4, providing a reliable positioning basis for subsequent lifting and lowering movements. Furthermore, under the constraint and guidance of the guide groove 6, the guide bracket 2 can perform smooth and precise lifting and lowering movements relative to the base 4 along the guide groove 6.

[0085] The existence of the guide groove 6 has many important implications. In terms of motion accuracy, it can effectively limit the movement direction of the guide bracket 2 during the lifting process, prevent it from deviating, swaying or other unstable phenomena, and ensure that the guide bracket 2 always lifts and lowers along the predetermined axial direction. This ensures that the knob assembly 1 can accurately reach the required position and meet the precise requirements for the knob position in different usage scenarios.

[0086] In terms of structural stability, the guide groove 6 provides additional support and constraint for the guide support 2, enhancing the overall structural strength of the device. During the lifting and lowering movement of the guide support 2, it can withstand various forces and torques from the guide support 2, dispersing stress concentration, reducing deformation and damage caused by uneven stress, and improving the reliability and service life of the device.

[0087] From an assembly and maintenance perspective, the design of the guide groove 6 makes the installation and disassembly of the guide bracket 2 more convenient. During assembly, initial positioning can be completed simply by accurately inserting the guide bracket 2 into the guide groove 6, reducing assembly difficulty and cost. During maintenance, if it is necessary to inspect, repair, or replace the guide bracket 2 or related components, it also facilitates quick and accurate operation by the operator.

[0088] In summary, the guide groove 6 on the base 4 and the cooperative design between the guide bracket 2 and the guide groove 6 are important structural features that ensure the stable, accurate and reliable operation of the automatic lifting knob device.

[0089] Please refer to this again. Figure 3-5 In one embodiment of this invention, in order to further optimize the structural layout and operational stability of the automatic lifting knob device, a key component, a fixed base 7, is specially added to the automatic lifting knob device.

[0090] The fixed base 7 plays a crucial connecting and supporting role in the entire device. Its design fully considers the compatibility and stability requirements with the automatic lifting component 3 and the guide bracket 2. Structurally, the fixed base 7 has a specific shape and size, and its material selection has also undergone strict consideration to ensure that it can withstand the various forces and torques generated by the automatic lifting component 3 during operation, while also possessing good wear resistance and corrosion resistance to extend the service life of the device.

[0091] The automatic lifting assembly 3 is securely mounted on the guide bracket 2 via the fixed base 7. This mounting method is not a simple physical connection, but a carefully designed mechanical assembly structure. During assembly, the fixed base 7 and the guide bracket 2 are tightly joined through specific connection methods (such as bolt connection, welding, etc., the specific connection method can be determined according to actual design requirements and process requirements), ensuring sufficient connection strength and rigidity between the two. At the same time, a reliable connection and positioning method is also adopted between the automatic lifting assembly 3 and the fixed base 7, enabling the automatic lifting assembly 3 to be accurately installed on the fixed base 7 and maintain a stable relative position during operation.

[0092] The placement of the automatic lifting assembly 3 on the guide bracket 2 via the fixed base 7 offers several significant advantages. Firstly, this arrangement effectively transmits the driving force and motion generated by the automatic lifting assembly 3 to the guide bracket 2, ensuring that the guide bracket 2 can perform lifting and lowering movements as intended, thereby driving the knob assembly 1 to extend and retract. Secondly, the fixed base 7 provides a stable mounting platform for the automatic lifting assembly 3, reducing vibration and swaying during operation and improving the device's operational accuracy and reliability. Furthermore, this structural design facilitates the assembly, debugging, and maintenance of the device. During assembly, operators can easily install the automatic lifting assembly 3 onto the fixed base 7 and then connect the fixed base 7 to the guide bracket 2, reducing assembly difficulty and cost. During debugging and maintenance, it also facilitates the inspection, repair, and replacement of the automatic lifting assembly 3, improving the maintainability of the device.

[0093] In summary, in this embodiment, the addition of the fixed base 7 and the automatic lifting component 3, which are mounted on the guide bracket 2 via the fixed base 7, is of great significance for improving the overall performance and stability of the automatic lifting knob device.

[0094] Please refer to this again. Figure 3-5 and in conjunction with references Figure 8-10 In one embodiment of this invention, to further enhance the intelligence and operational accuracy of the automatic lifting knob device, an innovative lifting control component 8 is added to the automatic lifting knob device.

[0095] The lifting control component 8, as the core module for achieving precise position control in the entire device, integrates advanced sensor technology, signal processing technology, and control algorithms. It possesses high sensitivity and reliability, enabling it to acquire the lifting position information of the guide bracket 2 in real time and accurately. Simultaneously, the lifting control component 8 is also equipped with corresponding signal processing circuits and a microcontroller to process, analyze, and judge the signals collected by the sensors, and output corresponding control commands according to the preset control strategy.

[0096] The core function of the lifting control component 8 is to monitor the lifting position of the guide bracket 2. During the lifting movement of the guide bracket 2, the lifting control component 8 continuously tracks the real-time position of the guide bracket 2 through its built-in sensors and compares the collected position data with the preset safe position range in real time. Once it detects that the lifting position of the guide bracket 2 is close to or reaches the preset limit position (i.e., the critical point where it may rise too high or fall too low), the lifting control component 8 will respond immediately.

[0097] Specifically, when the guide bracket 2 rises to near its upper limit position, the lifting control component 8 will quickly send a control signal to cut off the power to the drive motor 301 or change its rotation direction, preventing the guide bracket 2 from continuing to rise. This avoids over-rising and damaging other components of the device or exceeding its designed operating range. Similarly, when the guide bracket 2 descends to near its lower limit position, the lifting control component 8 will also take timely control measures to prevent the guide bracket 2 from descending too far, ensuring the safe operation of the device.

[0098] By achieving precise control over the lifting position of the guide bracket 2, the lifting control assembly 8 effectively avoids a series of problems caused by the guide bracket 2 moving beyond its reasonable range. For example, it can prevent the knob assembly 1 from colliding with other parts of the device during extension or retraction, reducing mechanical wear and the probability of malfunctions; at the same time, it also ensures that the knob assembly 1 can accurately reach the user's required operating position when extended and accurately reach the required position when retracted, without affecting the overall appearance and space occupation of the equipment.

[0099] In summary, in this embodiment, the added lifting control component 8 and its monitoring and control function for the lifting position of the guide bracket 2 play a crucial role in improving the overall performance, safety, and user experience of the automatic lifting knob device.

[0100] Please refer to this again. Figure 4-5 In one embodiment of this invention, in order to achieve accurate monitoring and control of the lifting position of the guide bracket 2 in the automatic lifting knob device, the lifting control component 8 can preferably adopt a precision design based on the Hall effect, and its specific composition includes a PCB board 801, two Hall chips 802 and a magnet 803.

[0101] The PCB board 801, serving as the circuit carrier and control core of the entire lifting control assembly 8, is securely mounted on the guide bracket 2. It not only provides a reliable electrical connection platform for the Hall chip 802 but also integrates necessary signal processing circuits and control logic, enabling rapid and accurate processing of the signals acquired by the Hall chip 802 and generating corresponding control commands based on the processing results. The design of the PCB board 801 fully considers factors such as electromagnetic compatibility, heat dissipation performance, and anti-interference capabilities to ensure stable and reliable operation in complex working environments.

[0102] Two Hall effect chips 802 are carefully mounted on the PCB board 801 and reliably electrically connected to it. These two Hall effect chips 802 are arranged in an up-down configuration along the lifting direction of the guide bracket 2. This arrangement has been precisely calculated and experimentally verified to ensure accurate detection of the magnetic field of the magnet 803 at different positions during the lifting and lowering process of the guide bracket 2. The Hall effect chip 802 is a magnetic sensor based on the Hall effect, which converts the strength and direction of the magnetic field into an electrical signal output. In this embodiment, the Hall effect chips 802 at different positions determine the lifting and lowering position of the guide bracket 2 by real-time detection of the magnetic field generated by the magnet 803, thereby determining whether the guide bracket has reached the highest position corresponding to the extended state or the lowest position corresponding to the retracted state.

[0103] The magnet 803 is mounted on the base 4, its position fixed and corresponding to the lifting path of the guide bracket 2. The main function of the magnet 803 is to generate a stable magnetic field, which is detected by the Hall chip 802 during the lifting and lowering of the guide bracket 2. The magnetic field strength, shape, and installation position of the magnet 803 have been carefully designed and optimized to ensure a good match with the Hall chip 802, thereby guaranteeing the accuracy and reliability of the detection. During the lifting and lowering of the guide bracket 2, the relative movement between the magnet 803 and the Hall chip 802 causes a change in the Hall chip 802's ability to detect the magnetic field of the magnet 803. When the Hall chip 802 at different positions detects the magnetic field of the magnet 802, it converts the change in magnetic field into an electrical signal and transmits it to the PCB board 801.

[0104] Understandably, as the guide bracket 2 rises, the Hall chip 802 gradually approaches the magnet 803, and the detected magnetic field strength gradually increases. When the Hall chip 802 finally aligns with the magnet 803, the detected magnetic field strength reaches a preset threshold. At this point, the Hall chip 802 transmits a corresponding electrical signal to the PCB board 801, instructing the PCB board 801 to stop the automatic lifting assembly 3 from rising further, ensuring that the guide bracket 2 stops at its highest position. At this time, the knob assembly 1 is in the extended state, as shown... Figure 4 , Figure 8 and Figure 9 As shown. Similarly, as the guide bracket 2 descends, the lower Hall chip 802 gradually approaches the magnet 803, and the detected magnetic field strength gradually increases. When the lower Hall chip 802 finally aligns with the magnet 803, the detected magnetic field strength reaches a preset threshold. The Hall chip 802 transmits an electrical signal to the PCB board 801, notifying the PCB board 801 to stop the automatic lifting assembly 3 from descending further, so that the guide bracket 2 stops at its lowest position. At this time, the knob assembly 1 is in the retracted state, as shown. Figure 5 and Figure 10 As shown.

[0105] The PCB board 801 plays a crucial role in the entire lifting control process. On one hand, upon receiving external commands, it sends a start signal to the automatic lifting assembly 3 via the control circuit, thereby controlling the lifting movement of the guide bracket 2. On the other hand, when the PCB board 801 receives electrical signals transmitted by the Hall chip 802, it can quickly analyze and process these signals and send a stop signal to the automatic lifting assembly 3 according to preset control logic, thus achieving precise control of the lifting position of the guide bracket 2. Through this Hall effect-based closed-loop control system, the lifting control assembly 8 can ensure that the guide bracket 2 accurately reaches the predetermined position during the lifting process, improving the operating accuracy and reliability of the automatic lifting knob device.

[0106] In summary, the structural design of the lifting control component 8 in this embodiment, through the coordinated work of the PCB board 801, two Hall chips 802 and magnet 803, achieves precise monitoring and control of the lifting position of the guide bracket 2, providing a strong guarantee for the stable and reliable operation of the automatic lifting knob device.

[0107] It is understandable that, from the perspective of technical implementation and functional logic, the source of the instructions received by the PCB board 801 is not a critical limiting factor. Specifically, the sources of these instructions are diverse and flexible, and are not limited to a specific device or apparatus. Among them, the knob assembly 1, as a common and intuitive human-machine interface component, generates corresponding control signals through user operations such as rotation and pressing, which are then converted into instructions recognizable by the PCB board 801. However, this is not the only source of instructions.

[0108] Besides the knob assembly 1, other remote control devices can also serve as the source of commands. These remote control devices may employ wired or wireless communication technologies, such as Bluetooth, Wi-Fi, or infrared, to transmit the operation commands input by the user through the remote control interface to the PCB board 801 in the form of electrical signals. The forms of remote control devices are also diverse; they may be dedicated remote controls specifically designed for this automatic lifting knob device, or they may be applications integrated into smart terminals such as smartphones and tablets, allowing users to remotely control the PCB board 801 by operating the interface of these applications.

[0109] Regardless of whether the commands originate from the knob or other remote control devices, the core responsibility of PCB board 801 is to accurately receive, parse, and execute these commands. It possesses powerful signal processing capabilities and logical judgment functions, enabling it to perform a unified processing flow for commands from different sources. This ensures the device can achieve the corresponding functions according to the user's intentions, such as controlling the lifting and lowering of the guide bracket 2 or adjusting the state of the knob assembly 1. This open and compatible design, regardless of the command source, not only improves the ease of use and flexibility of the automatic lifting knob device but also provides strong support for its wide application in various scenarios.

[0110] In one embodiment of this invention, the knob assembly 1, as a key operating component for user interaction with the automatic lifting knob device, establishes a tight and reliable electrical connection with the PCB board 801. This electrical connection is achieved through specific circuit traces, connectors, or conductive contacts, ensuring the stability and accuracy of signal transmission.

[0111] When a user operates the knob assembly 1, such as by rotating or pressing, the sensors or switches inside the knob assembly 1 detect these operations and convert them into corresponding electrical signals, i.e., operation data. This operation data contains specific information about the user's operation, such as the rotation angle, speed, and pressing force, and is a direct reflection of the user's operating intention.

[0112] The knob assembly 1 sends this operation data to the electrically connected PCB board 801 in a timely and accurate manner. As the electronic control core of the entire device, the PCB board 801 integrates a variety of electronic components and circuits, and has powerful data processing, analysis and execution capabilities.

[0113] Upon receiving the operation data sent by the knob assembly 1, the PCB board 801 initiates its built-in data processing program. First, the operation data is preprocessed to remove potential noise and interference signals, ensuring data accuracy and reliability. Then, preset algorithms and logic are used to perform in-depth analysis of the processed data to interpret the user's operational intent. For example, the rotation angle and speed determine the desired parameter adjustment, and the pressure applied determines whether a specific function has been triggered.

[0114] Finally, PCB board 801 will perform corresponding operations based on the analysis results. These operations may include controlling the start, stop, forward and reverse rotation, and speed adjustment of drive motor 301 to achieve the lifting and lowering movement of guide bracket 2; or adjusting other functional parameters of the device, such as volume level, brightness level, etc.; and may also trigger specific applications or functional modules to provide users with a richer and more personalized user experience.

[0115] Through the electrical connection between the knob assembly 1 and the PCB board 801, and the processing, analysis and execution of operation data by the PCB board 801, a precise mapping and efficient interaction between user operation and device function is achieved, effectively improving the intelligence level and user experience of the automatic lifting knob device.

[0116] Please refer to this again. Figure 1 and 7 In one embodiment of this invention, the base 4 serves as an important support and mounting foundation for the automatic lifting knob device, and its structural design fully considers the installation and fixing requirements of the device on the equipment. Mounting holes 9 are carefully provided on the base 4.

[0117] The placement of mounting holes 9 is not arbitrary, but rather the result of rigorous engineering design and practical application considerations. In terms of dimensions, the diameter and depth of mounting holes 9 have been precisely calculated and optimized to ensure compatibility with commonly used fasteners (such as bolts and screws) for a secure and reliable connection. Furthermore, the distribution and number of mounting holes 9 have been carefully planned, typically determined based on the shape and size of the base 4 and the overall stress distribution of the device. This ensures even stress distribution after installation, preventing deformation or damage due to excessive localized stress.

[0118] The main function of the mounting hole 9 is to provide an interface for the fixed installation of the automatic lifting knob device. In practical applications, the operator can pass a suitable fastener through the mounting hole 9 and tighten it into the corresponding threaded hole pre-set on the equipment housing or other supporting structure. In this way, the automatic lifting knob device can be firmly fixed in the target position, ensuring that the device will not loosen or shift due to vibration, external impact, or other factors during use, thereby guaranteeing the stability and reliability of the device.

[0119] Although this application frequently uses terms such as "base" and "knob assembly," the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0120] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
