Description

Technical Field

[0001] This utility model relates to the field of adjustment and control equipment technology, and in particular to a knob panel. Background Technology

[0002] In various equipment such as home appliances, instruments, and industrial control devices, parameter setting and control are often achieved through adjustment components. Knob-type adjustment components have become one of the mainstream choices due to their ease of operation. Traditional knob-type adjustment components have a simple structure and generally achieve parameter adjustment by directly turning the knob to move the switch or adjustment element, which has met basic operation and control needs for a long time.

[0003] However, as users' demands for quality of life continue to rise, the need for precise temperature control, tactile feedback, and status visualization is becoming increasingly prominent. Traditional knob controllers are gradually revealing many shortcomings. On the one hand, their adjustment relies heavily on direct contact between the knob and the adjustment component. Due to structural design limitations, the adjustment accuracy is difficult to guarantee, often failing to precisely match users' needs for fine temperature control. On the other hand, traditional knobs have poor tactile feedback during adjustment, resulting in a lack of user comfort. Furthermore, most existing knob controllers lack an intuitive status display module, making it difficult for users to obtain key status information such as the current temperature in real time and clearly, leading to a poor human-computer interaction experience. In addition, some knob controllers with display functions have an unreasonable assembly structure design between the display component and the knob component. Either the assembly process is cumbersome, affecting production efficiency, or the connection stability is insufficient, easily leading to problems such as loosening and display abnormalities during long-term use, further reducing the user experience. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a knob panel that enables precise temperature adjustment, comfortable operation, intuitive status display, and stable component assembly, thereby improving user experience and extending equipment lifespan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A knob panel includes a panel body, on which a knob assembly is provided for adjustment control by toggling a control switch through a toothed structure, and a display component is provided on the knob assembly for displaying status and cooperating with the knob assembly.

[0006] Preferably, the panel body includes a panel base and a decorative panel mounted on the panel base. The panel base has a mounting part, and the mounting part is provided with a control switch. The decorative panel has a through hole for the knob assembly to pass through. The mounting part is located between the panel base and the decorative panel. By enclosing the mounting part between the panel base and the decorative panel, the control switch can be protected against dust and damage. The decorative panel serves both an aesthetic purpose and protects the internal structure. The through hole precisely matches the transmission between the knob assembly and the control switch, ensuring adjustment stability.

[0007] Preferably, the knob assembly includes a knob shell, a locking shell, and a connector. The connector engages with the knob shell, and the locking shell engages with the connector. The toothed structure is a control tooth on the knob shell that cooperates with the control switch. The locking shell is connected to the panel base to install the knob assembly on the panel body. The snap-fit ​​assembly of the knob shell, locking shell, and connector makes the installation of the knob assembly more convenient and the connection tight and not easy to loosen. The cooperation between the control tooth and the control switch can avoid adjustment errors and achieve precise temperature control. The fixation of the locking shell to the panel base further improves the overall installation stability.

[0008] Preferably, the knob housing includes an extension end, the extension end is provided with control teeth around its circumference, and at least two deformation grooves are provided at equal intervals on the extension end. A deformable deformation end is provided in each deformation groove, and a snap-fit ​​block is provided on the inner side of the deformation end. A limiting part is provided on the inner side of the knob housing. One end of the connector abuts against the limiting part, and the other end snaps into the snap-fit ​​block. The elastic deformation design of the deformation end allows the connector to be assembled with the knob housing without additional tools, making the operation efficient. The limiting part can realize the axial positioning of the connector, ensuring the coaxiality of each component. Combined with the circumferential arrangement of the control teeth, it improves the smoothness and feedback of rotation adjustment.

[0009] Preferably, one end of the locking shell is provided with a deformation groove, the deformation groove is provided with a deformable deformation end, the deformation end is provided with a locking block, and the end of the locking shell away from the locking block is provided with a retaining ring. The end of the locking shell with the deformation end is inserted into the connector, the deformation end engages with the connector, and the retaining ring abuts against the connector. The elastic locking structure of the deformation end simplifies the assembly process, while the retaining ring can limit the axial displacement of the locking shell and the connector. The two work together to ensure high coaxiality and stable transmission after the knob assembly is assembled, avoiding loosening of parts caused by frequent rotation.

[0010] Preferably, the display component includes a connecting shell and a display panel fixed on the connecting shell. The connecting shell is provided with a rotating end that engages with the knob component. The display panel is integrated on the knob component, allowing the user to intuitively view the temperature status when adjusting, without having to look at the main unit of the device, thus improving the human-computer interaction experience. The engaging engagement of the rotating end ensures that the display component is installed stably and does not affect the rotation adjustment function of the knob.

[0011] Preferably, the connecting shell is provided with a mounting groove, the display panel is fixed in the mounting groove, the screw end is provided with a snap-fit ​​groove, and the inner side of the snap-fit ​​shell is provided with a snap-fit ​​block that engages with the snap-fit ​​groove. The screw end engages with the snap-fit ​​block by rotation. The mounting groove ensures that the display panel is installed flat and firmly fixed, avoiding displacement or damage during use. The rotation snap-fit ​​method makes the assembly and disassembly of the display components more convenient and facilitates subsequent maintenance. At the same time, the cooperation between the snap-fit ​​block and the snap-fit ​​groove ensures a tight connection.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves precise parameter adjustment through the cooperation of the control teeth of the knob housing and the control switch, solving the problems of large adjustment errors and poor feel of traditional knobs. It also avoids the trouble of insufficient feedback during operation. Furthermore, the three-layer snap-fit ​​structure of the knob assembly, the elastic deformation design of the deformation end, the positioning of the limit part and the retaining ring, and the rotation snap-fit ​​and mounting groove fixation of the display component allow for quick positioning and disassembly without additional tools, significantly shortening assembly and maintenance time. In addition, the decorative panel and the panel base enclose the mounting part to protect the control switch, and the display panel intuitively presents status information, further avoiding the problem of inconvenient information viewing, ensuring smooth overall use, and effectively improving the practicality and operational efficiency of the adjustment and control equipment.

[0020] Example: Please see Figure 1-6A knob panel includes a panel body 1, a knob assembly 2, and a display assembly 3. The panel body 1 serves as the supporting base for the entire knob panel, used to install and fix the knob assembly 2 and provide a stable assembly reference. It includes a panel base 11 and a decorative panel 12. The panel base 11 is provided with a mounting part 14, which is used to arrange a control switch 15. The mounting part 14 is located between the panel base 11 and the decorative panel 12, forming a closed mounting space to protect the control switch 15. The decorative panel 12 is installed on the panel base 11, which not only provides an aesthetic decoration effect but also protects the internal structure. The decorative panel 12 is provided with a through hole 13 for the knob assembly 2 to pass through and cooperate with the control switch 15.

[0021] The knob assembly 2 is mounted on the panel body 1. Rotation of the knob assembly controls the adjustment of the control switch 15. Its toothed structure, working in conjunction with the control switch 15, improves adjustment accuracy. The knob assembly 2 includes a knob shell 21, a locking shell 22, and a connector 23, all assembled together via a snap-fit ​​mechanism. This assembly is convenient and the connection is stable. The connector 23 engages with the knob shell 21, and the locking shell 22 engages with the connector 23, forming a nested assembly structure that ensures synchronous transmission during rotation. The toothed structure consists of control teeth 212 on the knob shell 21. These control teeth 212 pass through the through-hole 13 on the decorative panel 12 and engage with the control switch 15 on the mounting part 14. When the knob shell 21 is rotated, the control teeth 212 rotate synchronously and actuate the control switch 15, achieving precise adjustment. The locking shell 22 connects to the panel base 11, stably mounting the entire knob assembly 2 on the panel body 1 and preventing loosening during rotation.

[0022] The knob housing 21 has an extension end 211, and the control teeth 212 are arranged along the circumference of the extension end 211 to ensure full contact with the control switch 15. The extension end 211 has multiple deformation grooves 213, which form a deformable end 214 that can be elastically deformed. The inner side of the deformable end 214 has a snap-fit ​​block 215, and the inner side of the knob housing 21 has a limiting part 216. One end of the connector 23 abuts against the limiting part 216 to achieve axial positioning, and the other end snaps into the snap-fit ​​block 215. Through the elastic deformation of the deformable end 214, the connector 23 and the knob housing 21 can be easily assembled, and the connection is stable after snapping and is not easy to loosen.

[0023] One end of the locking shell 22 is provided with a deformation groove 221, which forms a deformable end 222 that can be elastically deformed. A locking block 223 is provided on the deformable end 222. A retaining ring 224 is provided at the end of the locking shell 22 away from the locking block 223. The end of the locking shell 22 with the deformable end 222 is inserted into the connector 23. Through the elastic deformation of the deformable end 222, the locking block 223 is locked and fixed with the connector 23. At the same time, the retaining ring 224 abuts against the connector 23 to achieve axial positioning of the locking shell 22 and the connector 23, ensuring the coaxiality and transmission stability of the three after assembly.

[0024] The display component 3 is mounted on the knob component 2 and is used to display status information such as temperature for easy viewing by the user. It includes a connecting shell 32 and a display panel 31. The display panel 31 is fixed on the connecting shell 32 and serves as a human-machine interface. It can be a touch control panel, combining display and operation functions. The connecting shell 32 is provided with a screw end 33, which engages with the locking shell 22 of the knob component 2 to achieve stable assembly of the display component 3 and the knob component 2.

[0025] The connecting shell 32 is also provided with a mounting groove, and the display panel 31 is fixed in the mounting groove to ensure the flatness and stability of the display panel 31 after installation. The screw end 33 is provided with a snap-fit ​​groove 34, and the inner side of the snap-fit ​​shell 22 is provided with a snap-fit ​​block 225 that is adapted to the snap-fit ​​groove 34. By rotating the connecting shell 32, the snap-fit ​​block 225 is snapped into the snap-fit ​​groove 34, completing the assembly of the display component 3 and the snap-fit ​​shell 22. The assembly is convenient and the disassembly is easy, which facilitates subsequent maintenance.

[0026] In use, the user adjusts the temperature by rotating the knob housing 21. When the knob housing 21 is rotated, the knob housing 21 drives the control teeth 212 on the extension end 211 to rotate synchronously. During the rotation, the control teeth 212 precisely actuates the control switch 15 on the mounting part 14. The temperature is adjusted by triggering the control switch 15. Because the cooperation between the control teeth 212 and the control switch 15 is precise, the user can achieve fine control of the temperature according to their needs. Moreover, there is no jamming during the rotation, and the operation is comfortable.

[0027] During the adjustment process, the display panel 31 of the display component 3 displays information such as the current temperature status in real time. Users can intuitively view the adjustment results and grasp the operating status of the equipment without additional operation. The display panel 31 can be a touch control panel, and users can also perform auxiliary operations through the touch display panel 31, such as temperature setting, mode switching, etc., to expand the usage functions.

[0028] During long-term use, the components are tightly connected by a snap-fit ​​structure. The limiting part 216, the retaining ring 224 and other structures ensure stable axial positioning and prevent loosening of parts. The closed structure of the mounting part 14 effectively protects the control switch 15, and the decorative panel 12 protects the internal transmission structure. The overall structure is durable and can effectively extend the service life of the equipment.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
