Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioner technology, and in particular to a panel component and an air conditioner. Background Technology
[0002] Air conditioners in related technologies have a display screen on the panel, with buttons or touch areas for operation. However, this method of operation is rigid and monotonous and needs improvement. Furthermore, in related technologies, household appliances with knobs always have the knobs protruding from the appliance's surface, making the appliances still appear uninspired. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a panel component that provides a controllable knob, and the knob is retractable, improving the interactivity and fun of the panel component. When not in use, the knob retracts to mitigate problems such as bumps, dust accumulation, and accidental activation that may result from a protruding knob. Furthermore, since the drive device is located on the panel and works in conjunction with the knob, only the knob is driven to extend and retract relative to the panel, while the drive device itself does not need to extend or retract relative to the panel, thus reducing the difficulty of setting up the drive mechanism.

[0070] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0072] Hereinafter, with reference to the accompanying drawings, a panel component 1000 according to a first aspect embodiment of the present invention will be described.
[0073] See Figure 1 The panel component 1000 includes: a panel 100 and a knob assembly 200.
[0074] For example, panel component 1000 is an exterior component used to cover and protect the internal structure of a household appliance or related equipment. Panel component 1000 has a wide range of applications, such as in household appliances. Panel 100 is the panel of a household appliance. The type of household appliance is not limited, such as air conditioner 10000, washing machine, refrigerator, microwave oven, rice cooker, water heater, gas stove, water purifier, electric fan, etc.
[0075] See Figure 1 The panel 100 has a clearance hole 11. The configuration of the panel 100 is not limited; for example, it can be a single panel, or it can include a front panel and a panel support. The front panel is mounted on the front side of the panel support, and the clearance hole 11 is formed on the front panel. The panel support can form a groove or a cutout at the corresponding clearance hole. The form of the clearance hole 11 is not limited; for example, it can be a through hole penetrating the panel 100 (such as the front panel); or the panel 100 (such as the front panel) has a rearwardly recessed portion that defines a front-opening groove, the front opening of which constitutes the clearance hole 11.
[0076] Combination Figures 1-3 The knob assembly 200 includes a knob 10 and a drive device 20. The drive device 20 is in a transmission cooperation with the knob 10 to drive the knob 10 to extend outward and retract inward relative to the panel 100 through the clearance hole 11.
[0077] For example, the clearance hole 11 can be a through hole that passes through the panel 100, thereby facilitating the installation of the knob 10. For example, in conjunction with the structural design, the knob 10 can be installed at the clearance hole 11 along the direction from the inside of the panel 100 to the outside of the panel 100; or, in conjunction with the structural design, the knob 10 can be installed at the clearance hole 11 along the direction from the outside of the panel 100 to the inside of the panel 100.
[0078] The drive device 20 and the knob 10 are in a transmission engagement, allowing the drive device 20 to transmit power to the knob 10, causing the knob 10 to move relative to the drive device 20 to pass through the clearance hole 11. This achieves the effect of extending outwards and retracting inwards relative to the panel 100. Specifically, the knob 10 moves towards the outer side of the panel relative to the drive device 20 (extension movement) and towards the inner side of the panel relative to the drive device 20 (retraction movement). Here, "outer" refers to the outer side of the panel 100, i.e., the side of the panel 100 facing the user, and the opposite side is "inner," i.e., the inner side of the panel 100, i.e., the side of the panel 100 facing away from the user. The purpose of the "transmission engagement" is to transmit power through mechanical cooperation; the specific method is not limited, such as gear transmission, belt transmission, chain transmission, screw transmission, etc. The movement trajectory of the knob 10 is not limited; for example, it can move in a straight line to pass through the clearance hole 11, or it can move along a curve to pass through the clearance hole 11, etc.
[0079] "Inward movement" refers to the knob 10 moving towards the inside of the panel 100, that is, the outer end face of the knob 10 moving towards the direction closer to the panel 100. "Outward movement" refers to the knob 10 moving towards the outside of the panel 100, that is, the outer end face of the knob 10 moving away from the panel 100.
[0080] The final position of the knob 10 retracted relative to the panel 100 can be either with the outer end face of the knob 10 flush with the outer surface of the panel 100, or with the outer end face of the knob 10 retracted into the outer surface of the panel 100, or with the outer end face of the knob 10 protruding from the outer surface of the panel 100, as long as the protrusion height of the knob 10 relative to the panel 100 in the retracted final position is less than the protrusion height of the knob 10 relative to the panel 100 in the extended final position.
[0081] Here, "outer end face of knob 10" refers to the side surface of knob 10 away from the inner side of panel 100, that is, the side surface of knob 10 facing the user. "Outer surface of panel 100" refers to the outer surface of panel 100. "Protrusion height" refers to the distance between the outer end face of knob 10 and the outer surface of panel 100 along the extension and retraction direction of knob 10.
[0082] For example, knob 10 from Figure 2 The state shown Figure 3The movement shown is such that the clearance hole 11 is retracted inward, or for example, the knob 10 moves from... Figure 3 The state shown Figure 2 The state shown is a movement in which the object extends outward through the clearance hole 11.
[0083] In related technologies, the knobs of household appliances are typically positioned in a fixed location, always protruding from the appliance's surface. On one hand, this protrusion makes the knobs susceptible to bumps and knocks during use or transport. Impacts can damage the internal structure of the knob, affecting its normal function. Furthermore, being exposed, the knobs are prone to water ingress; moisture can corrode electronic components or cause short circuits, resulting in knob damage. On the other hand, protruding knobs easily accumulate dust. Dust buildup increases friction when the knob is turned, causing it to jam or even become unable to turn, severely impacting the user experience. In addition, accidental touches can alter the appliance's original settings, causing unnecessary inconvenience to the user.
[0084] In the technical solution of this application, the knob assembly 200 includes a knob 10 and a drive device 20. The drive device 20 can drive the knob 10 to extend and retract relative to the panel 100. When the knob 10 is needed, the knob 10 extends relative to the panel 100, making it convenient for the user to rotate the knob 10, for example, to allow the user to rotate the knob ring 41 of the knob 10 to input control commands. When the knob 10 is not needed, the knob 10 retracts relative to the panel 100, reducing the protrusion size of the knob 10 relative to the panel 100, saving space occupied on the outside of the panel 100, and improving the problems of bumps, dust accumulation, and accidental touches that may be caused by the knob 10 protruding from the panel 100.
[0085] Moreover, since the drive device 20 is driven by the knob 10, only the knob 10 is driven to extend and retract relative to the panel 100, while the drive device 20 does not need to extend and retract relative to the panel 100. This reduces the difficulty of installing and wiring the drive device 20 and improves the installation stability and working reliability of the drive device 20.
[0086] The adjustment functions of knob 10 are unlimited. For example, users can rotate knob 10 to select functions of air conditioner 10000 (such as cooling, heating, dehumidification, fresh air, etc.), set values of air conditioner 10000 (temperature, fan speed, air direction, etc.), turn air conditioner 10000 on and off, or link with other functions of air conditioner 10000 (such as display, voice, lighting, etc.), or link with network-connected home appliances throughout the house. In addition, knob 10 can also be equipped with a touch screen and / or floating parts, allowing adjustment of the knob through touch and / or pressing.
[0087] For example, the drive device 20 is mounted on the panel 100. In this way, the drive device 20 is close to the position of the knob 10 that needs to pass through the clearance hole 11, thereby making the assembly between the knob 10 and the drive device 20 more precise, reducing the problem of poor fit caused by assembly tolerance, thus ensuring that the knob 10 and the drive device 20 are well assembled, the overall structure is compact and the working together is smooth. When the drive device 20 drives the knob 10 to move, it can reduce the possibility of damage to the drive device 20 caused by improper assembly or uncoordinated movement, improve the stability and reliability of the knob assembly 200, and extend the service life of the product. In addition, the overall design of the knob assembly 200 is complete, and the cooperation relationship between the various components is clear. During the installation process, it is only necessary to install the entire knob assembly 200 onto the panel 100, which simplifies the installation process and improves the installation efficiency. Of course, the location of the drive device 20 in this application is not limited to this. The drive device 20 may not be installed on the panel 100. For example, in other embodiments of this application, when the knob assembly 200 is used for the air conditioner 10000, the drive device 20 may also be installed on the air outlet frame or internal support of the air conditioner 10000 or other structural components, which will not be elaborated here.
[0088] In some embodiments, see Figures 1-3 The knob 10 is positioned opposite to the clearance hole 11, and the drive device 20 drives the knob 10 to reciprocate in a straight line.
[0089] Because the knob 10 moves in a straight line, the transmission design between the drive device 20 and the knob 10 is facilitated, and the risk of interference and collision between the knob 10 and the edge of the clearance hole 11 during movement is reduced. For example, the knob 10 reciprocates between an extended position and a retracted position along a straight line. The movement from the retracted position to the extended position is an extension relative to the panel 100 in a straight line, and the movement from the extended position to the retracted position is a retraction relative to the panel 100 in a straight line.
[0090] Although the knob 10 moves along a straight line, the knob 10 can be either a translational motion or a non-translational motion. That is, when the knob 10 extends or retracts relative to the panel 100 along a straight trajectory, the knob 10 itself can be a fixed translational motion without rotation, or a non-translational motion that moves along a straight line while also rotating.
[0091] The linear movement direction of the knob 10 can be perpendicular to the panel 100 or not. For example, when the panel 100 where the knob 10 is located is oriented in a way that is convenient for the user to operate, the linear movement direction of the knob 10 can be perpendicular to the panel 100. When the panel 100 where the knob 10 is located is oriented in a way that is inconvenient for the user to operate, the linear movement direction of the knob 10 can be not perpendicular to the panel 100. For example, it can move in a straight line diagonally upward, diagonally downward, or diagonally to the left or right.
[0092] For example, the center of the knob 10 and the center of the clearance hole 11 are approximately on the same straight line. The knob 10 includes a knob ring 41, which surrounds the outer periphery of the knob 10 and is held and rotated by the user to input commands. The orthographic projection of the knob ring 41 along the linear movement direction of the knob 10 falls completely into the clearance hole 11, thereby ensuring that the knob 10 can smoothly pass through the clearance hole 11 during linear movement, realizing reciprocating linear movement to extend and retract relative to the panel 100.
[0093] In some embodiments, see Figures 1-4 The knob 10 includes a core part 10a and a rotating part 10b. The rotating part 10b is rotatably engaged with the core part 10a so that it can rotate relative to the core part 10a. The driving device 20 is engaged with the core part 10a to drive the core part 10a to reciprocate.
[0094] For example, the rotating part 10b surrounds at least a portion of the outer periphery of the core part 10a. That is, the rotating part 10b may completely surround the outer periphery of the core part 10a, or it may only surround a portion of the outer periphery of the core part 10a. For example, the rotating part 10b may include a knob ring 41, which surrounds the outer periphery of the knob 10 and is held and rotated by the user to input commands.
[0095] In the above technical solution, the core part 10a in the knob 10 performs a reciprocating translational motion under the driving action of the driving device 20, so that the knob 10 moves back and forth along a straight line. The translational motion is simple and direct, and can accurately control the range of motion of the knob 10. This reduces the risk of the knob assembly 200 colliding with the panel 100 during the movement and extends the service life of the knob 10.
[0096] The core portion 10a reciprocates in a translational motion, meaning it does not rotate. This allows the orientation of associated components (such as screens or circuit boards) to be fixed, preventing rotation. For example, if the knob 10 integrates a screen 51 for displaying information, and the screen 51 is part of the core portion 10a, the fixed orientation of the screen 51, due to the non-rotating translational motion of the core portion 10a, eliminates the need for user adjustment to clearly view the content, improving user experience. Similarly, when a circuit board is part of the core portion 10a, the non-rotating translational motion of the core portion 10a prevents twisting or tangling of the wiring connected to the circuit board, improving product reliability. The type of screen 51 is not limited; it can be a simple display screen, a touchscreen, or a voice-interactive screen.
[0097] For example, the screen 51 can be located at the axial outer end of the knob ring 41. "Axial outer end of the knob ring 41" refers to the end of the knob 10 axially away from the interior of the panel 100. In the above technical solution, setting the screen 51 at the axial outer end of the knob ring 41 allows the user to directly see relevant operation feedback and display information on the knob 10 when rotating it. For example, if the screen 51 is set on the knob 10 of an air conditioner 10000, when the user rotates the knob 10 to adjust the temperature, the screen 51 can display the currently set temperature value in real time. Thus, the user can promptly understand whether the operation of rotating the knob 10 to adjust the temperature is effective and the current status of the device. The interaction is more intuitive, improving the convenience and accuracy of user operation. Furthermore, integrating the screen 51 onto the knob 10 eliminates the need for additional display areas in other parts of the device, saving overall space on the knob 10.
[0098] In the embodiments of this application, the driving device 20 drives the core portion 10a to reciprocate and translate. The driving method is not limited; exemplarily, it can be a threaded screw drive or a rack and pinion drive. For example, when a threaded screw drive is used, the driving device 20 may include a motor 61, the output shaft of which is connected to a screw 62a. The core portion 10a can engage with the screw 62a through a threaded hole. When the motor 61 drives the screw 62a to rotate, the core portion 10a is restricted from rotating, and the rotational motion of the screw 62a is converted into the reciprocating and translating motion of the core portion 10a, thereby realizing the extension and retraction function of the knob 10.
[0099] For example, when using a rack and pinion drive, the drive device 20 may include a motor 61, with a gear mounted on the output shaft of the motor 61. The core part 10a includes a rack that meshes with the gear. When the motor 61 drives the gear to rotate, it converts the rotational motion of the gear into the reciprocating translational motion of the rack, thereby driving the core part 10a and the knob 10 to perform reciprocating translational motion, thus realizing the extension and retraction function of the knob 10.
[0100] In some embodiments, see Figures 1-3 The drive device 20 includes a mounting base 20b and a driver 20a. The mounting base 20b is mounted on the panel 100, and the driver 20a is mounted on the mounting base 20b. The driver 20a is in a transmission engagement with the core part 10a, and the mounting base 20b is in a rotation-limiting engagement with the core part 10a.
[0101] "Cooperation with the core part 10a" means restricting the core part 10a from rotating around the rotation axis of the knob 10. "Rotation axis of the knob 10" refers to the rotation axis of the part of the knob 10 that is rotated by the user (e.g., the knob ring 41) when the user rotates the knob 10 to input a command.
[0102] Therefore, the drive device 20 has a simple structure, requiring only two parts: one for mounting and the other for driving. The mounting part (i.e., the mounting base 20b) engages with the core part 10a to limit its rotation, ensuring that the core part 10a does not rotate. The driving part (i.e., the driver 20a) engages with the core part 10a to drive it, enabling the core part 10a to obtain driving force for linear movement, thus meeting the overall telescopic movement requirements of the knob 10. This drive device 20 has a simple structure, making it easy to manufacture and design. Furthermore, mounting the driver 20a on the mounting base 20b, and mounting the mounting base 20b on the panel 100, makes the entire drive device 20 a relatively compact integrated unit, which helps improve assembly efficiency and saves space.
[0103] For example, the mounting base 20b is mounted on the panel 100. The mounting base 20b can be mounted on the inner side of the panel 100, and the driver 20a is also located on the inner side of the panel 100 and connected to the mounting base 20b. For instance, the mounting base 20b can be fixedly connected to the panel 100 via a connecting structure (such as bolts, clips, etc.), and the driver 20a can be fixedly connected to the mounting base 20b via a connecting structure (such as bolts, clips, etc.) to ensure the stability and reliability of the driver 20a mounted on the mounting base 20b, thereby improving the reliability and stability of driving the knob 10. At the same time, the installation positions of the mounting base 20b and the driver 20a do not affect the appearance and normal use of the panel 100, and can easily cooperate with the knob 10, ensuring a good fit between the knob 10 and the driving device 20, facilitating installation and implementation.
[0104] It is worth noting that the specific way in which the mounting base 20b and the core part 10a restrict rotation is not limited. For example, the structure in the mounting base 20b used to restrict the rotation of the core part 10a can be designed in various ways. For another example, the structure in the core part 10a that is restricted to rotation by the mounting base 20b can also be designed flexibly.
[0105] It is worth noting that the type of knob according to the embodiments of this application is not limited. It can be an encoder knob (incremental encoder), a capacitive touch knob, or a magnetoelectric knob, etc. Among them, the encoder knob (incremental encoder) contains an encoder. The encoder converts information such as the position and speed of mechanical motion into digital signals (pulses or codes) that can be recognized by the controller through photoelectric, electromagnetic, capacitive sensing methods, so as to realize accurate measurement and feedback of motion state. For example, when the knob is rotated, the code disk of the encoder rotates accordingly. Light is alternately blocked by the stripes of the code disk. The photosensitive sensor receives the intermittent light signal and converts it into an electrical pulse signal. The circuit calculates the rotation angle and direction of the knob according to the number and direction of the pulses (forward / reverse rotation) and outputs a digital signal to the device processor to realize adjustment. The surface of the capacitive touch knob is made of capacitive sensing material and integrates a capacitive sensor. When the finger rotates, the capacitance value between the finger and the knob surface changes. The sensor detects the frequency and direction of the capacitance change and converts it into an electrical signal. The chip interprets it as a rotation action to realize adjustment. The magnetoelectric knob has a permanent magnet installed inside and a Hall sensor arranged around it. When the knob is rotated, the direction of the magnetic field of the permanent magnet changes. The Hall sensor detects the change in magnetic field, generates a corresponding electrical signal, and transmits it to the processor to achieve adjustment.
[0106] For example, refer to Figure 4 The knob 10 includes an encoder 21, which includes an encoder rotating part 21a and an encoder fixing part 21b. The rotating part 10b includes the encoder rotating part 21a, the core part 10a includes the encoder fixing part 21b, and the mounting base 20b is in rotation-limiting cooperation with the encoder fixing part 21b.
[0107] The encoder 21 includes an encoder rotating part 21a and an encoder fixed part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixed part 21b. The rotating part 10b includes the encoder rotating part 21a and a knob ring 41. The knob ring 41 surrounds the outer circumference of the knob 10 and is fixed relative to the encoder rotating part 21a. The knob ring 41 is for the user to hold and rotate to input commands. The specific structural form of the encoder rotating part 21a and the encoder fixed part 21b is not limited. It can be a ring with inner and outer rings or other forms, which will not be described in detail here.
[0108] The core portion 10a includes an encoder fixing portion 21b. The mounting base 20b engages with the encoder fixing portion 21b to limit rotation, keeping the encoder fixing portion 21b of the encoder 21 fixed and preventing the core portion 10a from rotating. Thus, the encoder fixing portion 21b provides a stable reference for the encoder 21, reducing errors or malfunctions in the encoder 21's command acquisition caused by the rotation of the core portion 10a. This ensures that the encoder 21 can accurately and stably detect the rotation information of the encoder rotating portion 21a relative to the encoder fixing portion 21b, thereby accurately transmitting the user's control commands and improving the operational reliability of the knob 10.
[0109] The "rotation-limiting engagement between mounting base 20b and encoder fixing part 21b" can be implemented in various ways. For example, by setting specific limiting structures on mounting base 20b and encoder fixing part 21b, such as keyways, pins, snaps, or hole-shaft engagements with non-circular surfaces, the rotation of core part 10a can be limited.
[0110] Furthermore, in order to achieve the "limited rotation engagement between mounting base 20b and core 10a", it is not limited to the limited rotation engagement between mounting base 20b and encoder fixing part 21b. For example, the limited rotation engagement between mounting base 20b and other structural components (such as knob bracket 31) included in core 10a can also prevent the encoder fixing part 21b and core 10a from rotating.
[0111] In some embodiments, reference Figures 4-6 The mounting base 20b includes a mating section 712b that extends into the knob 10 and engages with the core portion 10a to limit rotation. This simplifies the structure of the mounting base 20b and facilitates the assembly of the mounting base 20b with the core portion 10a and the stable limiting of rotation of the core portion 10a. Furthermore, the engagement of the mating section 712b with the core portion 10a can be a rotational engagement between the mating section 712b and the encoder fixing part 21b of the core portion 10a, or it can be a rotational engagement between the mating section 712b and other structural components included in the core portion 10a (such as the knob bracket 31).
[0112] For example, refer to Figures 4-6 The encoder fixing part 21b is an inner ring 212, and a plurality of limiting grooves 2121 are formed on the inner ring 212 at intervals along the circumference. The limiting grooves 2121 extend along the axial direction of the inner ring 212. The mating section 712b extends into the inner ring 212 and includes a plurality of rotation limiting protrusions 7122. The plurality of rotation limiting protrusions 7122 and the plurality of limiting grooves 2121 are inserted and mated with each other along the axial direction.
[0113] In the above technical solution, the limiting groove 2121 extends axially along the inner ring 212, and the limiting protrusion 7122 cooperates with the limiting groove 2121, so that during the translational movement of the core part 10a, the limiting protrusion 7122 always slides within the limiting groove 2121, ensuring the continuity and stability of the limiting cooperation, and effectively preventing the core part 10a from rotating around the rotation axis of the knob 10 during the movement.
[0114] Multiple rotation-limiting protrusions 7122 and multiple limiting grooves 2121 are inserted and engaged one-to-one along the axial direction, i.e., the rotation-limiting protrusions 7122 and the limiting grooves 2121 are engaged at multiple points, which increases the stability and reliability of rotation limitation. Compared with single-point or a few-point engagement, multi-point engagement can better disperse the force and reduce the risk of loosening of the fit or damage to the inner ring 212 due to excessive local force. In addition, the multi-point engagement can restrict the inner ring 212 (core part 10a) from multiple directions, effectively preventing the rotation of the core part 10a. At the same time, since the limiting grooves 2121 extend along the axial direction, the rotation-limiting protrusions 7122 and the limiting grooves 2121 also have a certain engagement length in the axial direction, further enhancing the stability of rotation limitation.
[0115] For example, refer to Figures 4-6 The encoder rotating part 21a is the outer ring 211, and the encoder fixing part 21b is the inner ring 212, with the outer ring 211 fitted over the inner ring 212. This structure, where the outer ring 211 is fitted over the inner ring 212, provides a certain level of support and positioning for the entire knob 10. When the inner ring 212 is firmly restricted from rotation by the mounting base 20b, the relative rotational movement between the outer ring 211 and the inner ring 212 of the encoder 21 accurately reflects the user's operation of the knob 10. Therefore, the encoder 21 can accurately detect the rotation angle and positional changes of the outer ring 211 relative to the inner ring 212, thereby providing accurate control signals to the equipment controlled by the knob 10 and improving the accuracy and reliability of control via the knob 10.
[0116] For example, refer to Figures 4-6The mounting base 20b includes a motor base 71, which is an integrated structural component and includes a mating section 712b. The mating section 712b also includes a first rod 7121. Multiple rotation-limiting protrusions 7122 are located outside the first rod 7121 and are spaced apart circumferentially along the first rod 7121. The core part 10a includes a knob bracket 31, which is an integrated structural component and includes a connecting section 312. The connecting section 312 extends into the inner ring 212 and includes a second rod 3121 and a first buckle 3122. The second rod 3121 extends into the first rod 7121 to engage with the first rod 7121. The first rod 7121 is sleeved and guided, and the first buckle 3122 is located outside the first rod 7121 and is spaced circumferentially along the first rod 7121. Multiple retaining ribs 2122 are formed on the inner circumferential wall of the inner ring 212, spaced circumferentially. These retaining ribs 2122 and multiple limiting grooves 2121 are alternately arranged. The multiple first buckles 3122 and the multiple retaining ribs 2122 are correspondingly engaged. A clearance area 312a is defined between adjacent first buckles 3122, and multiple rotation-limiting protrusions 7122 are correspondingly located within the clearance area 312a. In the above technical solution, the motor base 71 and the knob bracket 31 are integrated structural components, reducing the number of parts, lowering assembly difficulty and cost, and making the fit between the drive device 20 and the knob 10 more compact, resulting in higher drive reliability.
[0117] It is worth noting that the specific manner in which the driver 20a and the core 10a are coupled is not limited. For example, the structure in the driver 20a used to transmit power to the core 10a can be designed in various ways, and the structure in the core 10a driven by the driver 20a can also be designed flexibly.
[0118] In some embodiments, see Figures 4-7 The knob 10 includes an encoder 21, which includes an encoder rotating part 21a and an encoder fixing part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixing part 21b. The rotating part 10b includes the encoder rotating part 21a. The core part 10a includes the encoder fixing part 21b and also includes a knob bracket 31. The knob bracket 31 is fixed to the encoder fixing part 21b. The driver 20a is in a driving engagement with the knob bracket 31 to apply a translational driving force to the core part 10a. Of course, in other embodiments of this application, the driver 20a may also be configured to be in a driving engagement with the encoder rotating part 21a.
[0119] In the above technical solution, the driver 20a engages with the knob bracket 31 in a transmission cooperation, rather than directly engaging with the encoder fixing part 21b of the encoder 21. This simplifies the structure of the encoder fixing part 21b and eliminates the need to consider bearing the driving force, thereby reducing the design difficulty of the encoder 21. In the embodiments of this application, the fixed connection between the knob bracket 31 and the encoder fixing part 21b of the encoder 21 is not limited; for example, it can be a snap-fit connection, a key connection, etc. The transmission cooperation method between the driver 20a and the knob bracket 31 is not limited; it can be gear transmission, belt transmission, chain transmission, screw transmission, etc.
[0120] In some embodiments, see Figures 4-7 The mounting base 20b is matched with the core part 10a for limited rotation. The driver 20a includes a motor 61 and a drive shaft 62. The drive shaft 62 is constructed as a screw 62a. The core part 10a includes a threaded hole 31213 that engages with the screw 62a. The motor 61 is used to drive the drive shaft 62 to rotate.
[0121] In the above technical solution, since the mounting base 20b and the core part 10a are matched with a rotation limit, the rotation of the core part 10a is effectively prevented. When the motor 61 drives the screw 62a to rotate, the threaded hole 31213 on the core part 10a that is engaged with the screw 62a cannot rotate with the screw 62a due to the rotation limit constraint of the mounting base 20b. It can only make translational movements along the axial direction of the screw 62a. Thus, the rotational movement of the screw 62a is converted into the linear movement of the core part 10a, which in turn drives the knob 10 to achieve linear translational extension and retraction. This transmission and matching method is simple, reliable and easy to control.
[0122] For example, by adjusting the speed, direction, and start / stop of the motor 61, the translational extension speed, extension direction, and stopping position of the knob 10 can be controlled. When the motor 61 stops working, the friction between the screw 62a and the threaded hole 31213 prevents the core 10a from moving under the action of gravity or other external forces, thus keeping the knob 10 at its current extension position. Therefore, by controlling the start / stop of the motor 61, the screw 62a can be stopped at any angle, allowing the core 10a to remain at any position along the axial direction of the screw 62a. This means that the extension height of the knob 10 is adjustable, not limited by fixed positions, achieving stepless adjustment of the extension height, improving the flexibility and applicability of the knob 10, and better meeting the usage habits of different users and the application needs of different scenarios. Of course, the control and setting of the motor 61 can also be used to make the knob 10 only stop at the extended and retracted positions, without stopping at other positions.
[0123] For example, when the core part 10a also includes a knob bracket 31, and the knob bracket 31 is fixed to the encoder fixing part 21b, the knob bracket 31 may include a threaded hole 31213 that engages with the screw 62a. The screw 62a engages with the threaded hole 31213 on the knob bracket 31. When the motor 61 drives the screw 62a to rotate, the rotation of the knob bracket 31 is restricted due to the rotation-limiting cooperation between the mounting seat 20b and the core part 10a, so that the knob bracket 31 can only move along the axial direction of the screw 62a, thereby driving the knob 10 to achieve linear telescopic movement. This reduces the uncertainty and the possibility of failure in the transmission process, and ensures that the knob 10 can achieve smooth and accurate linear translation, improving the stability and reliability of the equipment operation. In addition, by controlling the speed, direction and start / stop of the motor 61, the number of rotations of the screw 62a can be adjusted, thereby allowing the knob bracket 31 to stop at a specified position in the axial direction.
[0124] For example, see Figures 4-7 The mounting base 20b includes a mating section 712b, which includes a first rod 7121. The drive shaft 62 extends into the first rod 7121. The core part 10a includes a connecting section 312, which includes a second rod 3121. The second rod 3121 has a threaded hole 31213 inside. The second rod 3121 extends into the first rod 7121 and is sleeved on the outside of the drive shaft 62. The threaded hole 31213 inside the second rod 3121 means that the threaded hole 31213 is located inside the second rod 3121 and is fixed relative to the second rod 3121.
[0125] In the above technical solution, the first rod 7121, as part of the mating section 712b of the mounting base 20b, provides a guiding function for the second rod 3121. Since the second rod 3121 extends into the first rod 7121, when the drive shaft 62 drives the second rod 3121 to perform axial translational movement through the threaded hole 31213, the first rod 7121 can limit the radial sway of the second rod 3121, thereby making the movement of the core part 10a and the entire knob 10 more stable, reducing vibration and deviation during the movement, and improving the stability of the extension and retraction movement of the knob 10.
[0126] Furthermore, the second rod 3121 is sleeved outside the drive shaft 62 and extends into the first rod 7121, thereby increasing the connection strength between the components. The first rod 7121, the second rod 3121, and the drive shaft 62 cooperate to form a relatively stable sleeve structure, which can effectively resist external interference forces and torques, preventing the knob 10 from loosening or falling off during its telescopic movement, thus improving the reliability and stability of the knob 10's telescopic movement. In addition, the first rod 7121 protects the drive shaft 62, reducing the possibility of the drive shaft 62 coming into contact with dust or water, thereby improving the reliability and stability of the transmission engagement.
[0127] For example, the mounting base 20b includes a motor base 71, which is an integrated structural component and includes a mating section 712b. The mating section 712b includes a first rod 7121 and a rotation-limiting protrusion 7122. In the above technical solution, the motor base 71 is an integrated structural component, and the mating section 712b of the motor base 71 includes the first rod 7121 and the rotation-limiting protrusion 7122, thereby reducing the number of parts, lowering the assembly difficulty and cost, and improving the overall strength and stability of the motor base 71. The integrated structure can better withstand external forces, such as the guiding force and the rotation-limiting force, thereby enhancing the reliability of the guiding and rotation-limiting fits and improving the reliability and stability of the knob 10's movement.
[0128] For example, the second rod 3121 is a one-piece molded part and forms a threaded hole 31213. One-piece molding means that the second rod 3121 is a single structure with no connecting parts between its internal components, avoiding stress concentration and loosening problems caused by connecting parts. The one-piece molded structure can withstand greater external forces and torques, improving the stability and reliability of the knob bracket 31 during operation and reducing the risk of knob assembly 200 failure due to structural damage.
[0129] Furthermore, from a manufacturing perspective, the one-piece molding allows for the manufacture of the second rod 3121 and the threaded hole 31213 in a single process, reducing machining steps and assembly stages. It also makes it easier to ensure the coaxiality of the threaded hole 31213 and the second rod 3121, thereby improving the fitting accuracy between the knob bracket 31 and the drive shaft 62 and making the movement of the knob assembly 200 smoother. From a usage perspective, because it is one-piece molded, there are no gaps or joints inside the second rod 3121, providing excellent sealing. This prevents dust, moisture, and other impurities from entering the threaded hole 31213, reducing wear and corrosion and extending the service life of the knob assembly 200.
[0130] Or, for example, refer to Figure 8The second lever 3121 includes a lever body 31211 and a nut 31212. The nut 31212 is embedded in the lever body 31211 and forms a threaded hole 31213. Therefore, the nut 31212 can be replaced as needed. For example, different nuts 31212 can be used depending on the screw 62a, improving compatibility. Furthermore, if the second lever 3121 does not mesh well with the drive shaft 62, or if the threaded hole 31213 is worn or damaged, the nut 31212 can be replaced without replacing the entire second lever 3121, improving the maintainability of the knob assembly 200. In addition, the second lever 3121 consists of a lever body 31211 and a nut 31212. The lever body 31211 and the nut 31212 can be made of different materials. For example, the lever body 31211 can be made of plastic to make the knob assembly 200 lighter; while the nut 31212 can be made of a wear-resistant and high-hardness material, such as stainless steel or cast iron.
[0131] In some embodiments, combined with Figures 4-8 The knob 10 includes an encoder 21, which includes an inner ring 212. The core part 10a includes the inner ring 212 and a knob bracket 31. The knob bracket 31 includes a connecting section 312, which extends into the inner ring 212 and also includes a first buckle 3122. The mating section 712b extends into the inner ring 212. The first buckle 3122 is connected to the second rod 3121 and is located outside the first rod 7121 and is engaged and fixed to the inner ring 212.
[0132] In the above technical solution, the first buckle 3122 is snapped and fixed to the inner ring 212, connecting the knob bracket 31 and the inner ring 212 together, so that the knob bracket 31 and the inner ring 212 can be relatively fixed and move synchronously. By limiting the rotation of one of them (for example, limiting the rotation of the inner ring 212), neither of them can rotate, achieving the effect of limiting the rotation of the core part 10a as a whole. Furthermore, by driving one of them (for example, driving the knob bracket 31), the two can move synchronously, achieving the effect of the core part 10a moving as a whole.
[0133] Furthermore, the method of securing the first clip 3122 to the inner ring 212 makes installation and maintenance more convenient. During installation, simply align the first clip 3122 with the slot of the inner ring 212 to complete the engagement. When disassembly and maintenance are required, the first clip 3122 can be detached from the inner ring 212, reducing the difficulty and cost of processing and maintenance.
[0134] For example, the knob bracket 31 is an integrated structural component, with the second rod 3121 and the first buckle 3122 integrally connected, reducing the number of parts, lowering assembly difficulty and cost, while improving the overall strength and stability of the knob bracket 31. The integrated structure can better withstand external forces, making the overall structure of the knob 10 more stable and reliable, ensuring the reliability of the knob 10's movement when frequently raising and lowering it.
[0135] In some embodiments, a plurality of limiting grooves 2121 are formed on the inner ring 212 at circumferential intervals. The limiting grooves 2121 extend axially along the inner ring 212. The mating section 712b also includes a rotation limiting protrusion 7122. The rotation limiting protrusion 7122 is disposed on the outer peripheral wall of the first rod 7121. There are multiple rotation limiting protrusions 7122, which are spaced circumferentially along the first rod 7121. The multiple rotation limiting protrusions 7122 are inserted into the multiple limiting grooves 2121 one by one along the axial direction. There are multiple first buckles 3122, which are spaced around the first rod 7121. Figure 2 An avoidance zone 312a is defined between adjacent first buckles 3122, and multiple avoidance zones 312a correspond to multiple rotation limit protrusions 7122.
[0136] In the above technical solution, the first buckle 3122 is snapped and fixed to the inner ring 212, so that the knob bracket 31 and the inner ring 212 are fixedly connected together to form the core part 10a. The insertion and cooperation between the rotation limiting protrusion 7122 and the limiting groove 2121 restricts the rotation of the core part 10a. Multiple avoidance areas 312a avoid multiple rotation limiting protrusions 7122 one by one, so that the first buckle 3122 and the rotation limiting protrusion 7122 can avoid interference in a limited space, which improves the overall structural compactness of the knob 10 and reduces the volume and weight of the knob assembly 200.
[0137] For example, combined Figure 6 The mounting base 20b includes a mating section 712b, which includes a first rod 7121. Four rotation-limiting protrusions 7122 are provided on the outer peripheral wall of the first rod 7121 and are evenly spaced along the circumference of the first rod 7121. Figure 5 The inner ring 212 has four circumferentially spaced limiting grooves 2121, which extend axially along the inner ring 212. Four rotation-limiting protrusions 7122 are axially engaged with the four limiting grooves 2121, thereby limiting the rotation of the inner ring 212 at multiple angles in the radial direction. Figure 4The connecting section 312 includes a second rod 3121 and a first buckle 3122. The second rod 3121 extends into the first rod 7121. There are four first buckles 3122 that are equally spaced around the first rod 7121. A clearance area 312a is defined between two adjacent first buckles 3122, thus forming four clearance areas 312a. The four rotation-limiting protrusions 7122 are located in the four clearance areas 312a respectively.
[0138] In some embodiments, reference Figure 7 The drive device 20 includes a first rod 7121 that extends into the knob 10. The knob 10 includes a second rod 3121 that is inner and outer engaged with the first rod 7121 for guidance (e.g., the second rod 3121 is sleeved outside the first rod 7121, or the first rod 7121 is sleeved outside the second rod 3121) to constrain the knob 10 to move linearly relative to the panel 100.
[0139] In the above technical solution, the first rod 7121 extends into the knob 10, and the second rod 3121 is inner and outer connected and guided with the first rod 7121. This restricts the movement direction of the knob 10, making it move only along the connection direction of the first rod 7121 and the second rod 3121. This reduces the possibility of the knob 10 deviating, wobbling or tilting during movement, improves the stability of linear motion, and allows the knob 10 to extend or retract smoothly. The inner and outer connecting guide engagement method makes full use of space, making the structure of the drive device 20 and the knob 10 more compact. This helps to reduce the size of the knob assembly 200 and facilitates the installation of the knob assembly 200 in a limited space.
[0140] For example, the drive device 20 is engaged with the core part 10a to limit rotation, thereby preventing the second rod 3121 from rotating relative to the first rod 7121. Both the first rod 7121 and the second rod 3121 are hollow rods. The first rod 7121 is sleeved on the outside of the second rod 3121. The second rod 3121 has a threaded hole 31213 inside. The drive device 20 includes a motor 61 and a drive shaft 62. The drive shaft 62 extends into the second rod 3121. The drive shaft 62 is a screw 62a and meshes with the threaded hole 31213. The motor 61 is used to drive the drive shaft 62 to rotate.
[0141] In the above technical solution, both the first rod 7121 and the second rod 3121 are hollow rods, and the first rod 7121 is sleeved outside the second rod 3121. Compared with the non-nested structure, the space occupied by the components in the radial direction is reduced, making the combination of the entire drive device 20 and the core part 10a more compact, which is convenient for installation and layout in a limited space.
[0142] Both the first rod 7121 and the second rod 3121 are hollow rods, with the first rod 7121 sleeved outside the second rod 3121. This allows the first rod 7121 to restrict the radial sway of the second rod 3121, ensuring that the second rod 3121 can only move axially. This makes the movement of the knob bracket 31 and the entire knob 10 more stable. Furthermore, the drive shaft 62 is a screw 62a that meshes with the threaded hole 31213 inside the second rod 3121. The threaded drive has the characteristic of good transmission stability, further increasing the stability of the knob 10 in linear motion.
[0143] In some embodiments, see Figure 9 and Figure 10 The mounting base 20b includes a motor base 71, which is an integrally molded part and includes a base end plate 711 and a base shaft 712. The base end plate 711 is located on the side of the knob 10 away from the panel 100. The base shaft 712 passes through the base end plate 711. The portion of the base shaft 712 located on the side of the base end plate 711 near the knob 10 is a first rod 7121, and the portion of the base shaft 712 located on the side of the base end plate 711 away from the knob 10 is a limiting ring 7123. An axially oriented... The positioning hole 712a is through. A limiting boss 611 protrudes from one side of the motor 61 facing the seat end plate 711. The limiting boss 611 extends into the positioning hole 712a through the limiting ring 7123. The second rod 3121 extends into the positioning hole 712a from the end of the first rod 7121 away from the limiting ring 7123. The limiting boss 611 and the second rod 3121 are both clearance-fitted with the positioning hole 712a. The drive shaft 62 is coaxially arranged with the motor 61 and extends into the second rod 3121 through the limiting boss 611.
[0144] In the above technical solution, the motor base 71 integrates the base plate 711 and the base shaft 712 into one piece. The base shaft 712 serves as both the first rod 7121 and the second rod 3121, and also limits the motor 61 through the limiting ring 7123. This reduces the number of parts and makes the entire drive device 20 and knob 10 more compact in their fit, saving space and making it easier to install in a limited space. The limiting boss 611 on the motor 61 extends into the positioning hole 712a of the seat shaft 712, and the second rod 3121 extends into the positioning hole 712a from the end of the first rod 7121. Both the limiting boss 611 and the second rod 3121 are in clearance fit with the positioning hole 712a. For example, the fit clearance can be 0.05mm-0.1mm. This can improve the coaxiality among the drive shaft 62, the first rod 7121 and the second rod 3121, improve the stall problem of the motor 61, and prevent loosening or displacement during the movement, thereby improving the stability and reliability of the telescopic movement of the knob 10.
[0145] See Figure 9 and Figure 10For example, a first chamfer 71231 is formed at the end of the limiting ring 7123 near the motor 61, and a second chamfer 31214 is formed on the outer periphery of the end of the second rod 3121 near the motor 61. Thus, by setting the first chamfer 71231 at the end of the limiting ring 7123 near the motor 61 and the second chamfer 31214 on the outer periphery of the end of the second rod 3121 near the motor 61, the first chamfer 71231 and the second chamfer 31214 serve a guiding function during assembly, making it easier for the limiting boss 611 and the second rod 3121 to extend into the positioning hole 712a, reducing interference and jamming during assembly, and improving assembly efficiency.
[0146] In some embodiments, the first rod 7121 is a hollow rod with a cylindrical hole of uniform cross-section inside, and the outer peripheral surface of the second rod 3121 is formed as a cylindrical surface of uniform cross-section. The first rod 7121 is sleeved on the outside of the second rod 3121, and the cylindrical hole and the cylindrical surface are fitted with a fitting gap of 0.05mm-0.1mm. The cylindrical hole of uniform cross-section means that the cross-sectional shape and area remain unchanged along the axial direction of the first rod 7121, and the cylindrical surface of uniform cross-section means that the cross-sectional shape and area remain unchanged along the axial direction of the second rod 3121.
[0147] In the above technical solution, the first rod 7121 is a hollow rod with a cylindrical hole of uniform cross-section inside, and the outer circumferential surface of the second rod 3121 is a cylindrical surface of uniform cross-section. The two are fitted together and guided, so the second rod 3121 and the first rod 7121 are tightly fitted together and guided in the axial direction of the first rod 7121, providing a stable guiding effect for the knob 10. Thus, during the movement of the knob 10, it can prevent the knob 10 from deviating or shaking, and improve the accuracy and reliability of the movement of the knob 10.
[0148] In the above technical solution, the clearance is controlled within the range of 0.05mm-0.1mm. This ensures that the second rod 3121 can slide or rotate smoothly within the first rod 7121 without causing loosening due to excessive clearance, which would affect the reliability of the knob 10's movement. Simultaneously, it reduces friction between the first rod 7121 and the second rod 3121. If the clearance is too small, the two rods will generate significant friction during relative movement, accelerating the wear of both rods. Controlling the clearance within 0.05mm-0.1mm ensures smooth movement while keeping friction within a reasonable range, reducing the wear rate and extending the service life of both rods.
[0149] In some embodiments, the hole is a cylindrical hole and the cylindrical surface is a cylindrical surface. This results in a simple structure, easy processing, and easy assembly, requiring no attention to orientation. Furthermore, when the second rod 3121 and the first rod 7121 are guided and fitted together, the second rod 3121 can rotate relative to the first rod 7121 by a certain angle. This facilitates alignment with other structures. For example, the clearance area 312a defined between the first latches 3122 can be adjusted to correspond one-to-one with the rotation-limiting protrusion 7122 of the mating section 712b of the motor mount 71, thereby allowing both the knob bracket 31 and the motor mount 71 to smoothly engage with the inner ring 212 of the encoder 21 (the knob bracket 31 engages with the inner ring 212, and the motor mount 71 engages with the inner ring 212), thus improving the ease of assembly of the knob 10.
[0150] Combination Figure 4 , Figure 6 and Figure 7 In some embodiments, the knob 10 includes an encoder 21, which includes an encoder rotating part 21a and an encoder fixing part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixing part 21b. The panel assembly 100 includes a motor base 71, which is located inside the panel 100 and fixed relative to the panel 100. The motor base 71 is an integrated structural component and includes a mating section 712b. The mating section 712b includes a first rod 7121 and a rotation limiting protrusion 7122. A second rod 3121 extends into the first rod 7121, and the rotation limiting protrusion 7122 is located outside the first rod 7121 and engages with the encoder fixing part 21b for rotation limiting.
[0151] In the above technical solution, the motor base 71 is an integrated structural component. The mating section 712b of the motor base 71 includes a first rod 7121 and a rotation-limiting protrusion 7122. The second rod 3121 extends into the first rod 7121, forming an inner and outer guide fit, so that the knob 10 can move linearly relative to the panel 100. The rotation-limiting protrusion 7122 engages with the encoder fixing part 21b to limit rotation, so that the knob 10 does not rotate during linear movement relative to the panel 100. Thus, the motor base 71 integrates both the inner and outer guide fit function and the rotation-limiting fit function, and is an integrated structural component. That is, the first rod 7121 and the rotation-limiting protrusion 7122 of the mating section 712b are manufactured by a one-time molding process, such as injection molding or die casting, rather than being assembled from multiple parts. This reduces the number of parts, lowers the assembly difficulty and cost, and improves the overall strength and stability of the motor base 71. The integrated structure can better withstand external forces, such as the guiding force and the rotation limiting force, thereby enhancing the reliability of the guiding and rotation limiting forces and improving the reliability and stability of the knob 10's movement.
[0152] Furthermore, since the rotation limiting protrusion 7122 directly engages with the encoder fixing part 21b to limit rotation, the encoder fixing part 21b is reliably restricted from rotating. This allows the user to precisely control the rotation of the encoder rotating part 21a when turning the knob 10, improving the accuracy of inputting commands to the knob 10 through rotation and avoiding command input deviations caused by the rotation of the encoder rotating part 21a.
[0153] See Figure 8 In some embodiments, the knob 10 includes a knob support 31, which is an integrated structural component and includes a connecting section 312. The connecting section 312 includes a second rod 3121 and a first buckle 3122. The first buckle 3122 is located outside the first rod 7121 and is engaged and fixed with the encoder fixing part 21b.
[0154] In the above technical solution, the knob bracket 31 is an integrated structural component and includes a connecting section 312. The connecting section 312 includes a second rod 3121 and a first buckle 3122. The second rod 3121 extends into the first rod 7121 to form an inner and outer guide fit, so that the knob bracket 31 can move linearly relative to the panel 100. The first buckle 3122 is engaged and fixed with the encoder fixing part 21b, so that the knob bracket 31 drives the encoder 21 to move linearly together. Thus, the knob bracket 31 integrates both the inner and outer guide fit function and the function of driving the encoder 21 of the knob 10 to move together as a whole. Moreover, it is an integrated structural component, that is, the second rod 3121 and the first buckle 3122 of the connecting section 312 are manufactured by a one-time molding process, such as injection molding or die casting, rather than being assembled from multiple parts. This reduces the number of parts, lowers the assembly difficulty and cost, and improves the overall strength and stability of the knob bracket 31. The integrated structure can better withstand external forces, such as the force of the guide and the force that drives the encoder 21 to move together. The overall structure of the knob 10 is more stable and reliable, ensuring the reliability of the knob 10's movement when the knob 10 is frequently raised and lowered.
[0155] Furthermore, the first snap-fit 3122 on the connecting section 312 is snapped into and fixed to the encoder fixing part 21b. Compared with bolt connections, welding, and other connection methods, this allows for quick and accurate connection of the knob bracket 31 and the encoder fixing part 21b during production and assembly, improving production efficiency. The first snap-fit 3122 is located outside the first rod 7121, making reasonable use of space. While fulfilling the connection function, it will not interfere with the installation and movement of other internal components of the knob 10. This makes the entire knob 10 structure more compact, which is beneficial for the miniaturization design of the knob 10.
[0156] Combination Figure 5 , Figures 7-8In some embodiments, the encoder rotating part 21a is an outer ring 211, and the encoder fixing part 21b is an inner ring 212. The outer ring 211 is sleeved on the outside of the inner ring 212, and the mating section 712b and the connecting section 312 both extend into the inner ring 212. A plurality of retaining ribs 2122 are formed on the inner peripheral wall of the inner ring 212, which are spaced apart in the circumferential direction. There are multiple first buckles 3122 that are spaced around the first rod 7121. The multiple first buckles 3122 are engaged with the multiple retaining ribs 2122 in a one-to-one manner, and the adjacent first buckles 3122 are separated by a clearance. The inner peripheral wall of the inner ring 212 has multiple circumferentially spaced limiting grooves 2121, which are alternately arranged with multiple retaining ribs 2122. The rotation limiting protrusions 7122 are protrusions on the outer peripheral wall of the first rod 7121. There are multiple rotation limiting protrusions 7122, which are arranged circumferentially spaced with the first rod 7121. The multiple rotation limiting protrusions 7122 are located in the multiple clearance areas 312a, and the multiple rotation limiting protrusions 7122 and the multiple limiting grooves 2121 are matched one by one to limit rotation.
[0157] In the above technical solution, the connecting section 312 of the knob bracket 31 extends into the inner ring 212 and is fixed by the first buckle 3122 to the retaining rib 2122 formed on the inner peripheral wall of the inner ring 212. The snap-fit method is simple to operate and improves the installation efficiency of the knob bracket 31 and the inner ring 212. Meanwhile, multiple first buckles 3122 and multiple retaining ribs 2122 are engaged in a one-to-one manner, which enhances the stability of the connection between the knob bracket 31 and the inner ring 212. An avoidance area 312a is defined between adjacent first buckles 3122, and multiple rotation limiting protrusions 7122 are located in the multiple avoidance areas 312a in a one-to-one manner. That is, the multiple avoidance areas 312a avoid the multiple rotation limiting protrusions 7122 in a one-to-one manner. The rotation limiting protrusions 7122 need to cooperate with the limiting grooves 2121 of the inner ring 212, which realizes the rotation limiting cooperation between the knob bracket 31 and the inner ring 212. While ensuring that the knob bracket 31 can be easily connected to the encoder 21, it will not affect the rotation limiting function of the rotation limiting protrusions 7122. Therefore, the inner ring 212 structure of the encoder 21 is relatively compact, which is conducive to the miniaturization of the knob 10.
[0158] In the above technical solution, multiple rotation-limiting protrusions 7122 and multiple limiting grooves 2121 are inserted and matched one by one along the axial direction. That is, the rotation-limiting protrusions 7122 and the limiting grooves 2121 are connected at multiple points, which increases the stability and reliability of rotation limitation. Compared with single-point or a few-point matching, multi-point matching can better disperse the force and reduce the risk of loosening of the fit or damage to the inner ring 212 due to excessive local force. In addition, the multi-point insertion matching method can limit the inner ring 212 from multiple directions, effectively limiting the rotation of the encoder fixing part 21b. The relative rotational motion between the encoder rotating part 21a and the encoder fixing part 21b can accurately reflect the angle of the knob 10 rotated by the user. Thus, the encoder 21 can accurately measure the rotation angle and position change of the encoder rotating part 21a relative to the encoder fixing part 21b, thereby providing accurate control signals for the equipment controlled by the knob 10 and improving the control accuracy and performance of the knob 10.
[0159] In some embodiments, combined with Figure 4 and Figure 5 The rotating part 10b also includes a knob ring 41, which defines the outer periphery of the knob 10. The knob ring 41 is held and rotated by the user to facilitate command input. Exemplarily, the extension direction of the rotation axis of the rotating part 10b (i.e., the rotation axis of the knob ring 41) is consistent with the linear motion direction of the knob 10. This simplifies the structural design, facilitates processing and assembly, and makes the entire drive device 20 more compact in spatial layout. All components can be arranged along the same direction, reducing space occupation and making the overall volume of the knob assembly 200 smaller. Of course, this application is not limited to this. For example, in other embodiments of this application, the extension direction of the rotation axis of the rotating part 10b can be set to form a certain angle with the linear motion direction of the knob 10, for example, an angle less than 45°.
[0160] In some embodiments, the linear motion direction of the knob 10 is perpendicular to the panel 100. This makes the installation and adjustment of the drive device 20 relatively easier, simplifies the structural design, and facilitates processing and assembly. However, this application is not limited to this. For example, in other embodiments of this application, the linear motion direction of the knob 10 may be set to form a certain angle with the normal of the knob 10, for example, an angle less than 45°.
[0161] In some embodiments, combined with Figure 7 and Figure 11 The knob 10 includes a screen 51, which is fixed relative to the core 10a. Therefore, when the core 10a moves, the screen 51 also moves in a translational motion without rotating. This means that when the knob 10 is extended, it always maintains a single orientation, making it easier for the user to observe and obtain the information displayed on the screen 51, thus improving the user experience.
[0162] For example, combined Figure 7 , Figure 11 and Figure 12 The knob 10 includes an encoder 21, which includes an inner ring 212 and an outer ring 211. The outer ring 211 is fitted outside the inner ring 212 and is rotatable relative to the inner ring 212. The rotating part 10b includes the outer ring 211 and a knob ring 41. The knob ring 41 surrounds the outer ring 211 and is engaged with the outer ring 211. The core part 10a includes the inner ring 212 and a knob bracket 31. The knob bracket 31 is an integrated structural component that passes through the inner ring 212 and is engaged with the inner ring 212. The screen 51 is mounted on the knob bracket 31. The knob 10 also includes a face cover 52, which covers the outside of the screen 51.
[0163] Therefore, the cover 52 provides good physical protection for the screen 51, reducing damage from impacts, scratches, and other external forces during daily use and extending the lifespan of the screen 51. Mounting the screen 51 onto the outer end of the knob bracket 31 reduces the difficulty of installation and improves the reliability of the screen 51 installation.
[0164] The assembly method of the faceplate 52 is not limited. For example, it can be fixed relative to the knob bracket 31, thus simplifying the overall structure of the knob 10 and facilitating assembly; or it can be fixed relative to the knob ring 41 and rotate synchronously, thereby improving sealing. For example, see reference... Figure 12 The edge of the knob cover 52 has a cover plate 521, which surrounds the end of the knob bracket 31 and engages with the knob bracket 31, thereby connecting the cover 52 and the knob bracket 31.
[0165] In some embodiments, combined with Figure 7 , Figures 11-13 The knob 10 includes an encoder 21, which includes an inner ring 212. The core part 10a includes the inner ring 212 and a knob bracket 31. The knob bracket 31 includes a support section 311 and a connecting section 312. The connecting section 312 extends into the inner ring 212 and engages with the inner ring 212. The support section 311 is located at the axial outer end of the connecting section 312 and defines a mounting groove 311a that opens in a direction away from the connecting section 312. The screen 51 is located in the mounting groove 311a.
[0166] Therefore, by setting up the knob bracket 31, the installation of the screen 51 is facilitated, and its connection with the inner ring 212 is achieved, making the knob bracket 31, screen 51, and inner ring 212 relatively fixed and preventing rotation. Furthermore, the screen 51 is installed within the mounting slot 311a of the knob bracket 31, which improves the working stability of the screen 51. Moreover, the screen 51's embedding within the mounting slot 311a reduces screen light loss, and the mounting slot 311a also shields against external light, reducing interference from external light on the screen 51's display. Thus, the display on the screen 51 is clearer and brighter, allowing users to read the information displayed on the screen 51 even in brightly lit environments.
[0167] For example, refer to Figures 5-8 The core part 10a includes a knob bracket 31, which is an integrated structural component and includes a connecting section 312 and a support section 311. The connecting section 312 includes a second rod 3121. The support section 311 is located at the axial outer end of the connecting section 312, that is, the end near the outer side of the panel 100, and defines a mounting groove 311a that opens outward toward the outer side of the panel 100. The screen 51 is assembled in the mounting groove 311a, thereby improving the installation stability and working reliability of the screen 51.
[0168] In the above technical solution, the knob bracket 31 adopts an integrated structural component, which reduces the number of parts and assembly processes, and improves the stability and reliability of the structure. The knob bracket 31 includes a support section 311 and a connecting section 312. The support section 311 is located at the axial outer end of the connecting section 312 and defines a mounting groove 311a that opens to the outside. The screen 51 is installed in the mounting groove 311a. In this way, the internal space of the knob bracket 31 is utilized to integrate the screen 51 into the knob 10. Without affecting the rotation function of the knob 10, the display function is integrated, providing users with more information display and interaction methods.
[0169] For example, see Figure 8 The knob 10 also includes a cover 52, which is in the form of a cover and includes a cover plate 522 and a cover plate 521. The cover plate 522 covers the outside of the screen 51, and the cover plate 521 extends from the edge of the cover plate 522 toward the inside and surrounds the support section 311 and is engaged with the support section 311.
[0170] In the above technical solution, the cover plate 522 is placed on the outside of the screen 51, which can protect the screen 51 from being scratched by sharp objects, protect the integrity of the screen 51 and its display function, and prevent dust, stains and other contaminants from adhering to the screen 51, thereby reducing damage to the screen 51 and reducing the problem of unclear display caused by dust entering the screen. The cover plate 521 surrounds the perimeter of the screen 51 and is snapped into the support section 311. First, the cover plate 521 is set without obstructing the screen 51 while meeting the installation requirements. Second, it does not require additional connectors or complex installation structures. The snap-fit connection method is simple to operate and can be quickly assembled, improving production efficiency. Moreover, the cover 52 and the screen 51 can be relatively fixed and do not rotate relative to each other, so there will be no friction between them. Of course, this application is not limited to this. For example, in other embodiments, the cover 52 can also be set to be relatively fixed to the knob ring 41, which will not be elaborated here.
[0171] Combination Figure 1 , Figures 11-13 For example, a first circuit board 32 is installed on the inner side of the support section 311, and a connecting section 312 passes through the first circuit board 32. The first circuit board 32 is connected to the screen 51. A second circuit board 22 is installed at the end of the inner ring 212 away from the support section 311. The second circuit board 22 is connected to the encoder 21. The first circuit board 32 is connected to the second circuit board 22. The driving device 20 includes a mounting base 20b and a driver 20a. The mounting base 20b is installed on the panel 100, and the driver 20a is installed on the mounting base 20b. A third circuit board 63 is provided inside the mounting base 20b. The third circuit board is electrically connected to the driver 20a and the second circuit board 22, respectively.
[0172] In the above technical solution, the inner ring 212, screen 51, first circuit board 32, second circuit board 22, and third circuit board 63 are all relatively fixed and stationary relative to the core 10a, without rotation. Therefore, the connecting wires used for electrical connections will not twist or entangle due to rotation, improving the reliability and stability of the knob assembly 200. In addition, the connection between the first circuit board 32 and the second circuit board 22 reduces the length and complexity of the wiring.
[0173] In some embodiments, combined with Figure 11 and Figure 12 The knob 10 includes an encoder 21 and a knob ring 41. The encoder 21 includes an inner ring 212 and an outer ring 211. The outer ring 211 is sleeved on the outside of the inner ring 212 and is rotatable relative to the inner ring 212. The knob ring 41 surrounds the outer ring 211 and is fixed to the outer ring 211. A second circuit board 22 is provided at the axial inner end of the knob ring 41. The second circuit board 22 is fixed to the inner ring 212. A first sealing ring 23 surrounds the outer periphery of the second circuit board 22. The first sealing ring 23 and the knob ring 41 are in axial (i.e., axial) clearance fit.
[0174] In the above technical solution, the knob 10 includes a first sealing ring 23, which surrounds the second circuit board 22 and is axially clearance-fitted with the knob ring 41. Thus, the first sealing ring 23 can prevent liquid from entering the inside of the knob 10, thereby protecting the knob 10, such as protecting important components inside the knob 10, such as the first circuit board 32 and the screen 51. This not only improves the reliability of the equipment in a humid environment, but also does not affect the rotation of the knob ring 41.
[0175] For example, refer to Figure 4 and Figure 5 The knob ring 41 includes a ring bracket 411 and a decorative ring 412. The ring bracket 411 surrounds the outer ring 211 and engages with the outer ring 211. The decorative ring 412 surrounds the ring bracket 411, and the outer surface of the decorative ring 412 can form the outer peripheral surface of the knob 10.
[0176] Therefore, the knob ring 41 consists of two parts. The structural design of the ring bracket 411 can meet the requirements of easy and reliable connection with the outer ring 211, and the decorative ring 412 can meet the appearance requirements of the knob 10. The appearance and material of the decorative ring 412 are not limited and can be flexibly designed and processed according to requirements.
[0177] For example, the connection method between the ring bracket 411 and the decorative ring 412 is not limited; for example, they can be snap-fitted or screw-connected (e.g., ...). Figure 4 (as shown), thus facilitating disassembly and assembly, as well as the replacement of the decorative ring 412, etc.
[0178] In some embodiments, combined with Figures 1-3 The drive device 20 includes a mounting base 20b and a driver 20a. The mounting base 20b is mounted on the panel 100, and the driver 20a is mounted on the mounting base 20b and is used to drive the knob 10 to move. The mounting base 20b includes a first ring 721, which is disposed around the knob 10. The panel component 1000 also includes a second sealing ring 8, which is sealed between the first ring 721 and the panel 100.
[0179] In the above technical solution, the second sealing ring 8 is disposed on the inner side of the panel 100 and is sealed between the first ring 721 and the panel 100. During the use of the knob assembly 200, when external water or other liquids seep into the inner side of the panel 100 through the clearance hole 11, the second sealing ring 8 can prevent liquids from seeping into the equipment (e.g., air conditioner 10000) equipped with the panel 100 through the gap between the first ring 721 and the panel 100. Combined with other drainage designs of the knob assembly 200, water seeping into the clearance hole 11 can be discharged according to the designed route, thereby protecting the safety of other components inside the equipment.
[0180] Furthermore, the second sealing ring 8 not only serves a waterproof function but also enhances the tightness of the connection between the first ring 721 and the panel 100 to a certain extent. The second sealing ring 8 has a certain degree of elasticity, generating pressure between the first ring 721 and the panel 100, ensuring a tight fit between the sealing ring and both. This stabilizes the connection between the first ring 721 and the panel 100, reducing loosening and displacement caused by vibration, shaking, and other factors. This ensures that the driver 20a can stably drive the knob 10, improving the structural stability of the knob assembly 200.
[0181] In some embodiments, combined with Figures 1-3 The knob 10 includes a knob ring 41 and a bottom plate 22a. The knob ring 41 is rotatable relative to the bottom plate 22a. A first sealing ring 23 surrounds the outer periphery of the bottom plate 22a. The first sealing ring 23 and the knob ring 41 are in axial (i.e., axial direction of the knob ring 41) clearance fit. The driving device 20 drives the knob 10 to reciprocate between an extended position and an inward position. In the extended position (refer to...) Figure 2 The second sealing ring 8 and the first sealing ring 23 form an abutment seal along the entire circumference of the first sealing ring 23.
[0182] In the above technical solution, when the knob 10 is in the extended position (refer to...) Figure 2 The second sealing ring 8 and the outer surface of the first sealing ring 23 (such as the first sealing surface 231) form an abutting seal along the entire circumference of the first sealing ring 23, thereby ensuring that the side of the bottom plate 22a away from the panel 100 is not corroded by moisture and improving the working reliability of the knob assembly 200. In addition, the clearance fit between the first sealing ring 23 and the knob ring 41 ensures that the knob ring 41 of the knob 10 can be smoothly turned by the user. The abutting seal between the second sealing ring 8 and the first sealing ring 23 restricts the radial and axial shaking of the knob 10 to a certain extent, improving the operating feel. In addition, the elasticity of the sealing ring can absorb some vibration and impact force, so that the knob 10 remains relatively stable in the extended position.
[0183] In some embodiments, combined with Figures 1-3 The mounting base 20b also includes a second ring 713, which is located within the first ring 721. The bottom plate 22a is a second circuit board 22. The side of the second circuit board 22 facing away from the panel 100 has electrical components, which are opposite to the space inside the second ring 713. In the retracted position (refer to...), Figure 3 The first sealing ring 23 and the second ring 713 form an abutment seal along the entire circumference of the first sealing ring 23.
[0184] In the above technical solution, when the knob 10 is in the retracted position (refer to...) Figure 3The second ring 713 and the inner surface of the first sealing ring 23 (such as the second sealing surface 232) form an abutment seal along the entire circumference of the first sealing ring 23, thereby providing reliable protection for the electrical components on the side of the second circuit board 22 away from the panel 100, effectively preventing external moisture, dust, foreign objects, etc. from entering the inner space of the second ring 713, reducing the possibility of short circuits, corrosion, damage, etc. of electrical components, improving the service life and stability of electrical components, and improving the reliability of the knob assembly 200.
[0185] Furthermore, the presence of the second ring 713 not only provides a mating surface for the first sealing ring 23 to abut and seal, but also indirectly supports and positions the second circuit board 22 to a certain extent. When the knob 10 is in the retracted position, the sealing fit between the second ring 713 and the first sealing ring 23 makes the entire structure of the knob 10 more stable, reducing the risk of loosening or damage to electrical components due to vibration, shaking, or other factors, thereby improving the reliability of the knob 10.
[0186] For example, such as Figures 1-3 As shown, the mounting base 20b is in the form of a cover, housing the knob 10 within it. The motor 61 is located outside the mounting base 20b, and the drive shaft 62 extends into the mounting base 20b and engages with the knob 10. For example, the mounting base 20b may include a motor mount 71 and a housing 72. The housing 72 is mounted inside the panel 100 and includes a first ring 721. The motor mount 71 is mounted on the housing 72 and covers the end of the first ring 721 that is away from the panel 100. Figure 6 and Figure 7 The motor mount 71 includes a mount end plate 711 and a first rod 7121. The edge of the mount end plate 711 is connected to a first ring 721. The first rod 7121 extends from the center of the mount end plate 711 toward the panel 100. The driver 20a includes a motor 61 and a drive shaft 62. The motor 61 is mounted on the side of the mount end plate 711 away from the panel 100. The drive shaft 62 is connected to the motor 61 and extends into the first rod 7121. The second ring 713 extends from the mount end plate 711 toward the panel 100. The first rod 7121 is located inside the second ring 713. The second ring 713 is located inside the first ring 721. The bottom plate 22a is a second circuit board 22. The side of the second circuit board 22 away from the panel 100 has electrical components. In the retracted position, the first sealing ring 23 and the second ring 713 form an abutment seal along the entire circumference of the first sealing ring 23. The bottom plate 22a may have a central hole 221 for the connecting section 312 to pass through.
[0187] In some embodiments, combined with Figures 1-3 The drive unit 20 drives the knob 10 to the extended position (e.g., Figure 2 (as shown in the diagram) and the inward position (e.g.) Figure 3The knob 10 reciprocates between the states shown, that is, the drive device 20 drives the knob 10 to move relative to the drive device 20 in the extended position (e.g., the state shown). Figure 2 (as shown in the diagram) and the inward position (e.g.) Figure 3 It moves back and forth between the states shown.
[0188] For example, in the retracted position, the height difference between the outer end face of the knob 10 and the outer surface of the panel 100 does not exceed 4mm, that is, the height difference is between -4mm and 4mm. In the retracted position, the outer end face of the knob 10 can be flush with the outer surface of the panel 100, recessed within the outer surface of the panel 100, or protrude from the outer surface of the panel 100, but the height difference (i.e., the distance along the direction of the panel 100) does not exceed 4mm. For example, it can be -4mm, -3.5mm, -3mm, -2.5mm, -2mm, -1.5mm, -1mm, -0.5mm, 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. This reduces the possibility of the knob 10 being accidentally touched, lowering the risk and loss caused by misoperation; furthermore, the retracted knob 10 is protected by the panel 100, reducing the impact and scratches from external objects on the knob 10. At the same time, it also makes it difficult for dust, moisture, etc. to enter the inside of the knob 10, thus improving the protective performance of the knob 10. Specifically, when the panel 100 is set facing forward, the front end of the knob 10 is the outer surface of the knob 10, and the front surface of the panel 100 is the outer surface of the panel 100.
[0189] For example, in the extended position, the height difference between the outer end face of the knob 10 and the outer surface of the panel 100 is 5mm-20mm. That is, in the extended position, the height difference (i.e., the distance along the direction of the panel 100) between the outer end face of the knob 10 and the outer surface of the panel 100 is 5mm to 20mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc. This satisfies the operational requirements without the knob 10 protruding excessively, thus simplifying the drive design, avoiding excessive space occupation, improving the user's operating feel, and preventing excessive shaking of the knob 10. When the panel 100 is facing forward, the front end face of the knob 10 is the outer surface of the knob 10, and the front surface of the panel 100 is the outer surface of the panel 100.
[0190] See Figure 14 An air conditioner 10000 according to a second aspect of the present invention includes a panel component 1000 according to any embodiment of the first aspect of the present invention.
[0191] The type of air conditioner 10000 is not limited. For example, it can be an integrated air conditioner, such as a kitchen air conditioner, a portable air conditioner, or a window air conditioner; it can also be a split air conditioner, such as a split wall-mounted unit, a split floor-standing unit, a ceiling-mounted air conditioner, or a built-in air conditioner.
[0192] According to the embodiment of the present utility model, the air conditioner 10000 provides a novel operating experience by setting the panel component 1000 of the first aspect, and the knob 10 is not easily damaged by bumps and has good reliability.
[0193] Users can adjust the temperature, fan speed, mode, and other parameters of the air conditioner 10000 by rotating the knob 10, which improves the operability of the air conditioner 10000. In addition, the knob 10 can extend outward when the control parameters of the air conditioner 10000 need to be adjusted, and retract inward when the control parameters of the air conditioner 10000 do not need to be adjusted, which increases the interactivity and fun of the air conditioner 10000 and meets users' needs for personalized products.
[0194] In some embodiments, the air conditioner 10000 is a split-type air conditioner and includes an indoor unit, the indoor unit including a panel component 1000; or, the air conditioner 10000 is an integrated unit and includes an indoor unit portion adapted to be installed indoors, the indoor unit portion including the panel component 1000. Thus, users can adjust parameters such as temperature, fan speed, and mode of the air conditioner 10000 by rotating the knob 10, improving the operability of the air conditioner 10000. Furthermore, the knob 10 can extend outward when the control parameters of the air conditioner 10000 need adjustment and retract inward when the control parameters do not need adjustment, increasing the interactivity and fun of the air conditioner 10000 and meeting users' needs for personalized products.
[0195] Other components of the air conditioner according to the embodiments of the present invention, such as heat exchangers and fans, as well as their operation, are known to those skilled in the art and will not be described in detail here.
[0196] The panel component 1000 according to a specific embodiment of the present application is described below.
[0197] The panel component 1000 includes a panel 100 and a knob assembly 200. The panel 100 has a clearance hole 11. The knob assembly 200 includes a knob 10 and a drive device 20. The knob 10 is disposed opposite to the clearance hole 11. The drive device 20 is mounted on the panel 100 and is in transmission cooperation with the knob 10 to drive the knob 10 to reciprocate in a straight line, so that the knob 10 passes through the clearance hole 11 and extends outward and retracts inward relative to the panel 100.
[0198] The knob 10 includes a core portion 10a and a rotating portion 10b. The rotating portion 10b is rotatably engaged with the core portion 10a so as to be rotatable relative to the core portion 10a. The drive device 20 drives the core portion 10a to reciprocate. The drive device 20 includes a mounting base 20b and a driver 20a. The mounting base 20b is mounted on the panel 100, and the driver 20a is mounted on the mounting base 20b. The driver 20a is in a transmission engagement with the core portion 10a to apply a linear driving force to the core portion 10a. The mounting base 20b is in a rotation-limiting engagement with the core portion 10a to restrict the rotation of the core portion 10a.
[0199] The knob 10 includes an encoder 21, which comprises an encoder rotating part 21a and an encoder fixing part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixing part 21b. The encoder rotating part 21a is an outer ring 211, and the encoder fixing part 21b is an inner ring 212. The outer ring 211 is sleeved on the outer ring 212. The rotating part 10b includes the outer ring 211 and a knob ring 41, which surrounds the outer ring 211 and engages with it. The core part 10a includes the inner ring 212 and a knob support 31. The knob bracket 31 is an integrated structural component and includes a support section 311 and a connecting section 312. The support section 311 is located at the axial outer end of the connecting section 312 and defines a mounting groove 311a that opens in a direction away from the connecting section 312. A screen 51 is provided in the mounting groove 311a. The connecting section 312 includes a second rod 3121 and a first buckle 3122. The first buckle 3122 is located on the outer peripheral wall of the second rod 3121. There are multiple first buckles 3122, which are evenly spaced along the circumference of the second rod 3121. The connecting section 312 extends into the inner ring 212. Multiple retaining ribs 2122 are formed on the inner peripheral wall of the inner ring 212 at intervals along the circumference. Multiple first buckles 3122 are engaged with the multiple retaining ribs 2122 in a one-to-one manner. The second rod 3121 has a threaded hole 31213 inside. Multiple limiting grooves 2121 are formed on the inner ring 212 at intervals along the circumference. The limiting grooves 2121 extend along the axial direction of the inner ring 212.
[0200] Mounting base 20b is a cover housing the knob 10. Driver 20a includes a motor 61 and a drive shaft 62. The motor 61 is located outside the mounting base 20b, and the drive shaft 62 extends into the mounting base 20b and engages with the knob 10. Mounting base 20b is an integrated structure and includes a mating section 712b. The mating section 712b includes a first rod 7121 and rotation-limiting protrusions 7122. Multiple rotation-limiting protrusions 7122 are located on the outer peripheral wall of the first rod 7121 and are evenly spaced along the circumference of the first rod 7121. The mating section 712b extends into the inner ring 212, and the multiple rotation-limiting protrusions 7122 engage with multiple limiting grooves 2121 axially. A clearance area 312a is defined between two adjacent first latches 3122, and the multiple rotation-limiting protrusions 7122 are located within the clearance areas 312a. The first rod 7121 is a hollow rod with a cylindrical hole of uniform cross-section inside. The outer circumferential surface of the second rod 3121 is formed as a cylindrical surface of uniform cross-section. The second rod 3121 and the first rod 7121 are fitted together in an inner and outer guide engagement to constrain the knob 10 to move linearly relative to the panel 100. The drive shaft 62 is constructed as a screw 62a. The drive shaft 62 extends into the first rod 7121, and the second rod 3121 extends into the first rod 7121 and is sleeved on the outside of the drive shaft 62.
[0201] In this way, when the motor 61 drives the screw 62a to rotate, the rotation of the inner ring 212 and the knob bracket 31 is restricted, and the rotational motion of the screw 62a is converted into the reciprocating translational motion of the inner ring 212 and the knob bracket 31, thereby realizing the overall telescopic function of the knob 10. The knob 10 is disassembled into components such as the knob bracket 31, the encoder 21, and the knob ring 41. These components are connected by simple snap-fit mechanisms, allowing the assembly process to be carried out in steps. Each component can be produced and assembled independently, reducing the complexity and difficulty of assembly and improving production efficiency.
