Description

TECHNICAL FIELD

[0001] The utility model relates to a knob, especially a knob device integrated with a display screen. BACKGROUND

[0002] With the deep integration of information technology and traditional mechanical devices, improving the intelligent degree of mechanical equipment and enhancing user interaction experience have become an important direction of product upgrading. As a key operating component widely used in safe equipment such as safes, doors, vaults, and security doors, the intelligent upgrading of the function of the knob is of great significance.

[0003] The traditional knob device mainly relies on a pure mechanical structure to work, and its basic components include a knob body, a connecting shaft, and a fixed base, etc. Users control the opening and closing of the lock mechanism by manually rotating the knob, which is widely used in safe equipment such as safes and vault doors. With the development of technology, some improved knob devices have appeared on the market, such as adding indicator marks around the knob, adding touch textures on the surface of the knob to improve the operation feeling, combining the knob with a digital keyboard to form a dual authentication mechanism, etc. Some high-end products also use electronic knobs that can record opening history, set opening permissions, etc. However, these improved knobs are still designed separately from the information display, i.e., the knob is only responsible for mechanical operation, and the information display is completed by the display screen or indicator light of other parts of the device, and the integration of the knob and the information display is not achieved.

[0004] In summary, the main drawback of the existing technical solution is that the traditional pure mechanical knob cannot provide real-time status feedback, and users cannot intuitively understand the current state of the device, such as lock state, opening countdown, error prompt, etc. In today's rapid development of information technology, this single-function mechanical knob cannot meet the user's demand for product intelligence and informatization. At the same time, the separate design (knob and display screen separated) requires the user to pay attention to two different positions of the knob and the display screen during operation, which reduces the operation convenience and user experience.

[0025] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Example 1: As Figures 1-4 As shown, a knob device with an integrated display screen includes,

[0027] A knob cover 1, with a display screen 2 embedded in its upper surface;

[0028] The knob body 3 has an upward-opening receiving cavity 4, and the knob cover plate 1 is fixed in the receiving cavity 4;

[0029] The knob base 5 is rotatably connected to the knob body 3, and a limiting mechanism for limiting the rotation angle of the knob body 3 is provided between the knob base 5 and the knob body 3.

[0030] Example 2: Figures 1-4 As shown, unlike Embodiment 1, the upper surface of the knob cover plate 1 has a recessed mounting cavity 7 at its center. The display screen 2 is fixed in the mounting cavity 7. The bottom of the mounting cavity 7 has a first wire harness groove 8, the bottom of the knob body 3 has a second wire harness groove 9, and the knob base 5 has a third wire harness groove 10. The first wire harness groove 8, the second wire harness groove 9, and the third wire harness groove 10 are interconnected to form a wire harness channel through which the connecting wires of the display screen 2 pass.

[0031] In the above structure, the recessed mounting cavity 7 at the center of the upper surface of the knob cover 1 provides a dedicated mounting space for the display screen 2, ensuring that the display screen 2 and the cover surface form a flat and integrated appearance. At the same time, the depth design of the mounting cavity 7 can effectively protect the display screen 2 from external impacts.

[0032] The first wire harness slot 8 is located at the bottom of the mounting cavity 7, serving as the starting channel for the connection cable of the display screen 2. The second wire harness slot 9 is located at the bottom of the knob body 3, acting as a relay for transmission. The third wire harness slot 10 is located on the knob base 5, connecting to the external control system. The three wire harness slots are interconnected through positional cooperation, forming a complete wire harness transmission path, allowing the power and signal cables of the display screen 2 to smoothly pass through the entire knob structure to reach the external control circuit. This structure avoids the complex manufacturing process of traditional hollow shaft transmission methods, reducing production costs and technical difficulty. Each component can also be processed and assembled independently, improving production efficiency and product maintainability.

[0033] In practical applications, this wiring harness channel can be optimized according to different needs: for low-power display screens, the wiring harness slot can be designed with a smaller cross-sectional area to save space; for applications requiring the transmission of high-frequency signals, a shielding layer can be added inside the channel to reduce electromagnetic interference; for environments with high requirements for waterproofing and dustproofing, a sealing ring structure can be added at the connection points of each channel. Furthermore, this design also reserves space for future functional expansion, such as adding connecting wires for microphones, sensors, and other electronic components within the same channel, enabling the multi-functional integration of the knob device.

[0034] In this embodiment, a rotating shaft 11 is fixedly provided at the lower end of the knob body 3, and a rotating hole 12 that cooperates with the rotating shaft 11 is opened in the center of the knob base 5, and the rotating shaft 11 is rotatably inserted into the rotating hole 12.

[0035] In the above structure, the fixed rotating shaft 11 at the lower end of the knob body 3 serves as the driving rotating element, and when the user applies a rotating torque, the rotating shaft 11 directly transmits the torque to the entire knob body 3. The rotating hole 12 at the center of the knob base 5 serves as the passive supporting element, providing radial support and axial positioning for the rotating shaft 11, and ensuring that the knob maintains the correct motion trajectory during rotation.

[0036] The cooperation between the rotating shaft 11 and the rotating hole 12 adopts a clearance fit method, which not only ensures the flexibility of rotation, but also ensures the stability of the connection, effectively preventing the jamming phenomenon caused by too tight fit or the shaking problem caused by too loose fit. The fixed setting method of the rotating shaft 11 makes it form an integrated structure with the knob body 3, which has high transmission efficiency and avoids the risk of loose connection. The opening position of the rotating hole 12 is located at the geometric center of the knob base 5, which ensures the concentricity of the rotating motion and reduces the vibration and wear caused by eccentricity.

[0037] In this embodiment, the limiting mechanism includes a limiting protrusion 13 arranged on the side wall of the rotating shaft 11 and a limiting groove 14 arranged along the edge of the rotating hole 12. The limiting protrusion 13 slides within the limiting groove 14 to limit the rotation angle of the knob body 3.

[0038] In the above structure, the limiting protrusion 13 on the side wall of the rotating shaft 11 serves as the motion limiting element and rotates synchronously with the rotating shaft 11. When the knob rotates, the limiting protrusion 13 slides within the limiting groove 14 along the edge of the rotating hole 12. The two end boundaries of the limiting groove 14 form mechanical stops. When the limiting protrusion 13 contacts the end of the groove, further rotation is prevented, thereby achieving precise limitation of the maximum rotation angle of the knob.

[0039] This convex-concave groove limiting design has significant technical advantages. The direct contact between the limiting protrusion 13 and the limiting groove 14 provides reliable mechanical stops, and the angle limitation can be achieved without additional electronic control systems, improving the reliability and response speed of the system. The arc length of the limiting groove 14 can also be flexibly adjusted according to actual needs, supporting customized settings for rotation angle ranges such as 90 degrees, 180 degrees, and 270 degrees. The sliding limiting method ensures smooth rotation and avoids sudden jamming, allowing users to feel clear feedback at the end of rotation and improving the operation experience.

[0040] Embodiment Three: As shown in Figures 1-4 Unlike Embodiment Two, the lower surface of the knob body 3 is provided with a plurality of gear grooves 15, and the knob base 5 is provided with elastic positioning protrusions 16 that cooperate with the gear grooves 15.

[0041] In the above structure, the plurality of gear recesses 15 on the lower surface of the knob body 3 are evenly distributed along an arc-shaped path to form discrete positioning points. When the knob is rotated, the elastic positioning protrusions 16 on the knob base 5 automatically search for and embed into the corresponding gear recesses 15 under the action of elastic force, achieving precise gear locking. The design of the elastic positioning protrusions 16 allows them to have a certain deformation capacity. When the user applies sufficient rotational torque, the elastic positioning protrusions 16 can pop out of the current gear recess 15 and slide to the next gear, thereby achieving smooth switching between gears.

[0042] The arc-shaped distribution of the gear recesses 15 allows the number and spacing of gears to be flexibly set according to the functional requirements of the device, supporting various configuration schemes such as 5 gears, 9 gears, 14 gears, etc., to meet the precision requirements of different application scenarios. The moderate resistance provided by the elastic positioning protrusions 16 provides clear tactile feedback for user operation, with a clear click feeling accompanying each gear switch, enhancing the certainty and controllability of operation. The elastic self-locking feature of the elastic positioning protrusions 16 ensures that the knob can be stably maintained at the current gear without external force, effectively preventing gear drift caused by vibration or accidental touch.

[0043] In this embodiment, the outer side wall of the knob body 3 is provided with a plurality of anti-slip grooves 17, which are evenly distributed along the outer peripheral surface of the knob body 3.

[0044] In the above structure, the plurality of anti-slip grooves 17 on the outer side wall of the knob body 3 form a regular concave-convex surface texture. When the user's fingers contact the knob surface, the frictional resistance of the contact interface can be significantly increased. The uniform distribution of the anti-slip grooves 17 along the outer peripheral surface ensures consistent anti-slip effect regardless of the user's grip angle, avoiding differences in operation stability caused by different grip positions.

[0045] In this embodiment, the knob cover plate 1 is provided with a microphone mounting groove 18, which is located on the inner side surface of the knob cover plate 1.

[0046] In the above structure, the microphone mounting groove 18 on the inner side surface of the knob cover plate 1 provides a dedicated mounting space and protection environment for the microphone element. The microphone forms a stable connection with the knob cover plate 1 through the mounting groove. When the user performs voice input, the sound signal can be transmitted to the microphone through the gap or specially designed sound channel of the knob, achieving clear audio signal collection. The inner side mounting method effectively protects the microphone from direct impact and pollution from the external environment, prolonging the service life of the device.

[0047] The intelligent control system of the knob device adopts an integrated design architecture, and realizes unified management and coordination of the display screen 2, the microphone and the wireless communication function through the built-in control module in the handle matched therewith. The control module, as the core processing unit, establishes stable power supply and data connection with the display screen 2 through the preset wire harness channel, is responsible for real-time updating of display content, brightness adjustment, display mode switching and other function controls, at the same time, the control module establishes an audio signal transmission path with the microphone, realizes voice signal collection, digitization processing and instruction recognition, supports voice control, voiceprint recognition and other intelligent interaction functions.

[0048] The significant feature of the intelligent control system is its strong connectivity and expandability. The control module is built-in with a WiFi wireless communication module, so that the knob device has remote communication and network connection capability, users can remotely control, monitor the state and set parameters through the smart phone APP, the WiFi connection function also supports firmware online upgrade, cloud data synchronization and remote fault diagnosis and other advanced functions, greatly improving the maintainability and user experience of the product. The control module adopts low-power design, supports multiple power supply modes, including battery power supply, external power supply or energy harvesting power supply, to ensure stable operation of the device in various environments.

[0049] In actual application scenarios, for example, for smart safe application, users can realize cloud storage of opening records through WiFi connection, when the safe is opened abnormally, the system can immediately send alarm information to the user's mobile phone, the display screen 2 can display the network connection state, battery power, current time and other information in real time, and the microphone supports voice password input and identity verification function. For smart home integration application, the knob device can be used as a smart home control center, connected to the home network through WiFi, users can control lighting, air conditioning, sound and other household appliances through rotation operation or voice command. The control module also supports the expansion of multiple communication protocols such as Bluetooth and Zigbee, providing a hardware foundation for building a complete Internet of Things ecosystem. The system also has learning ability, which can automatically adjust the display content and response mode according to the user's usage habits, realizing personalized intelligent experience.

[0050] In this embodiment, the upper surface of the knob base 5 is provided with an annular light guide protrusion 6. Thus, a continuous and uniform annular light band effect is formed around the knob base 5.

[0051] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
