Description

Technical Field

[0001] This application relates to the field of operation control technology, and in particular to a knob assembly, operation control system and electrical equipment. Background Technology

[0002] In the interactive design of electrical appliances, knobs have become a core component for function selection and parameter control due to their intuitive operating logic and continuous adjustment capabilities. By rotating clockwise or counterclockwise, users can select functions and steplessly adjust parameters such as volume, temperature, and brightness, providing more refined control precision.

[0003] However, if the knob rotates too smoothly during operation, resulting in a lack of tactile interaction between the user and the device, and the user cannot intuitively obtain feedback from the knob's operation, it will be difficult for the user to accurately control the degree of knob rotation. The user may easily over-rotate the knob due to inertia or hand tremors, which may lead to excessive function switching or excessive parameter adjustment, requiring the user to make repeated adjustments, resulting in a poor user experience. Utility Model Content

The second operating member is movably disposed on the first operating member. The second operating member can rotate synchronously with the first operating member and can slide along the axial direction of the first operating member. The encoder is connected to the second operating element and is used to detect the motion of the second operating element. An elastic limiting member is provided on the knob base. The elastic limiting member has an abutting portion facing the inner circumferential surface of the knob ring, and the elastic limiting member can extend and retract radially along the knob ring.

[0008] Optionally, the first operating member further includes a limiting plate, which is connected to the button ring and the rotating shaft respectively. The limiting plate is perpendicular to the axis of the first operating member and is used to limit the sliding stroke of the second operating member.

[0009] Optionally, the elastic limiting member includes an elastic element and a ball, with an abutting portion disposed on the surface of the ball, and the elastic element always having a tendency to press the ball against the inner circumferential surface of the button ring.

[0010] Optionally, the elastic limiting member further includes a limiting cylinder, which extends radially along the button ring, and the elastic member and the ball are disposed inside the limiting cylinder; in the radial direction of the button ring, the two ends of the elastic member abut against the inner wall of the limiting cylinder and the ball, respectively.

Function switching and / or parameter adjustment can be achieved by rotating the first operating member, and adjustment confirmation can be achieved by pressing the second operating member. During the rotation of the first operating member, since the knob base is provided with an elastic limiting member, the elastic limiting member can extend and retract radially along the knob ring. The elastic limiting member has an abutting part facing the inner circumferential surface of the knob ring. The inner circumferential surface of the knob ring is provided with multiple recesses. When the first operating member rotates, the abutting part can sequentially cooperate with the multiple recesses on the circumferential direction of the knob ring. When the user rotates the first operating member, he / she can perceive regular resistance changes and vibrations, and / or hear a "click" sound of the abutting part hitting the recesses. This provides a high-quality damping feel for the operation of the knob assembly, allowing the user to intuitively perceive the operation feedback of the knob assembly, thereby improving the operation quality of the knob assembly and thus improving the user experience.

Therefore, it naturally possesses the technical effects of the above-mentioned knob assembly. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. 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 this application. 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.

[0027] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0028] To address the technical problem in existing technologies where users cannot intuitively obtain feedback from the knob operation, which can easily lead to excessively rapid function switching or parameter over-adjustment, this application provides a knob assembly 1, an operation control system, and an electrical device. The knob assembly 1 includes a first operating element 12 and a second operating element 13 that can rotate synchronously. The second operating element 13 can slide along the axial direction of the first operating element 12. Function switching and / or parameter adjustment can be achieved by rotating the first operating element 12, and adjustment confirmation can be achieved by pressing the second operating element 13. During the rotation of the first operating member 12, since the knob base 11 is provided with an elastic limiting member 15, the elastic limiting member 15 can extend and retract radially along the knob ring 121, and the elastic limiting member 15 has an abutting part facing the inner circumferential surface of the knob ring 121. The inner circumferential surface of the knob ring 121 is provided with multiple recesses 1211. When the first operating member 12 rotates, the abutting part can cooperate with the multiple recesses 1211 on the circumferential surface of the knob ring 121 in sequence. When the user rotates the first operating member 12, he can feel the regular resistance change and vibration, and / or hear the "click" sound of the abutting part hitting the recesses 1211. This provides a high-quality damping feel for the operation of the knob assembly 1, allowing the user to intuitively perceive the operation feedback of the knob assembly 1, thereby improving the operation quality of the knob assembly 1 and thus improving the user experience.

[0029] Please see Figures 1 to 12 The first aspect of this application provides a knob assembly 1, including a knob base 11, a first operating member 12, a second operating member 13, an encoder 14, and an elastic limiting member 15. The knob base 11 can be used to fix the knob assembly 1 as a whole on the electrical equipment. The first operating member 12 is rotatably disposed on the knob base 11, and the adjustment function of the knob assembly 1 (i.e., function adjustment and / or parameter adjustment, etc.) can be realized by rotating the first operating member 12.

[0030] The first operating member 12 includes a knob 121, the inner circumferential surface of which has a plurality of recesses 1211, such as... Figure 1 , Figure 2 and Figure 3 As shown, the inner circumferential surface of the button ring 121 is uneven, that is, the radial distance from a point on the inner circumferential surface of the button ring 121 to the center of the button ring 121 varies periodically along the circumference of the button ring 121.

[0031] The second operating element 13 is movably mounted on the first operating element 12. The second operating element 13 can rotate synchronously with the first operating element 12, and the second operating element 13 can slide along the axial direction of the first operating element 12, so as to facilitate confirmation of the current adjustment state by pressing the second operating element 13. Figure 2 and Figure 6 As shown.

[0032] The encoder 14 is connected to the second operating element 13 and is used to detect the action of the second operating element 13. It can transmit the action parameters (such as rotation angle) of the first operating element 12 and the second operating element 13 to the circuit board 16 of the knob assembly 1 and convert the action signal of the second operating element 13 into an electrical signal so as to realize interactive control through the knob assembly 1.

[0033] An elastic limiting member 15 is disposed on the knob base 11. The elastic limiting member 15 has an abutting portion facing the inner circumferential surface of the knob ring 121, and the elastic limiting member 15 can extend and retract radially along the knob ring 121. When the first operating member 12 is in a stationary state, the abutting portion of the elastic limiting member 15 abuts against a recess 1211 on the inner circumferential surface of the knob ring 121. When the first operating member 12 rotates, the elastic limiting member 15 is stretched and retracted by the force of the uneven inner circumferential surface of the knob ring 121, and sequentially engages with multiple recesses 1211 on the inner circumferential surface of the knob ring 121. When the abutting portion of the elastic limiting member 15 is pressed against the recess 1211, a "click" sound is emitted, and there is a significant change in resistance and vibration when the first operating member 12 rotates (due to the impact of the abutting portion against the recess 1211), providing a high-quality damping feel for the operation of the knob assembly 1, allowing the user to intuitively perceive the operation feedback of the knob assembly 1.

[0034] It should be noted that in this application, the elastic limiting member 15 periodically engages with multiple recesses 1211 on the inner circumferential surface of the button ring 121. When the first operating member 12 (i.e., the button ring 121) rotates forward or backward, the abutting part is embedded in different recesses 1211, such as... Figure 3 As shown, the impact between the contact part and the recessed part 1211 will produce a "click" sound and a change in resistance, providing clear physical feedback to the user. The damping and sound feedback during the rotation of the first operating part 12 allow the user to perceive the adjustment progress without visual inspection, avoiding over-rotation or under-adjustment. It is especially suitable for blind operation scenarios, significantly improving the user's operating experience and the accuracy of equipment control.

[0035] In some embodiments of this application, please refer to Figure 2 and Figure 4 The knob base 11 has a through hole 111 at its center. The first operating member 12 has a rotating shaft 122 coaxially arranged with the through hole 111. The rotating shaft 122 is rotatably connected to the through hole 111 to facilitate the rotation operation of the first operating member 12. The rotating shaft 122 has a hollow channel 1221 at its center. The second operating member 13 has a connecting part 131 coaxially arranged with the hollow channel 1221. The connecting part 131 passes through the hollow channel 1221 and is connected to the encoder 14. This allows the second operating member 13 to pass through the first operating member 12 and the knob base 11 to connect with the encoder 14, which helps to achieve a compact arrangement of the knob assembly 1 and reduce the space occupancy rate of the knob assembly 1.

[0036] In some embodiments of this application, please refer to Figure 2 and Figure 4 The connecting part 131 of the second operating member 13 is sleeved on the outside of the input shaft 141 of the encoder 14. In order to enable the input shaft 141 of the encoder 14 to rotate synchronously with the second operating member 13, the second operating member 13 also includes a plug-in part 132 extending toward the encoder 14. The plug-in part 132 can be used to achieve a tenon-and-mortise connection with the input shaft 141 of the encoder 14 to prevent relative rotation between the second operating member 13 and the encoder 14.

[0037] In some embodiments of this application, please refer to Figure 2 and Figure 4 The rotating shaft 122 includes a plurality of ring-shaped snap-fit ​​plates 1222, which snap onto the circumferential edge of the through hole 111. Each snap-fit ​​plate 1222 has an arcuate surface for engaging with the through hole 111 and can rotate relative to it. The snap-fit ​​plates 1222 facilitating the assembly of the first operating member 12 with the knob seat 11 by engaging the edge of the through hole 111 facilitates the assembly of the first operating member 12 with the knob seat 11. The ends of the snap-fit ​​plates 1222 have barbs that hook onto the edge of the through hole 111 after assembly, preventing the first operating member 12 from detaching from the knob seat 11. The multiple snap-fit ​​plates 1222 enclose a hollow channel 1221, allowing the connecting portion 131 of the second operating member 13 to pass through the center of the first operating member 12 and connect to the input shaft 141 of the encoder 14, making the internal structure of the knob assembly 1 more compact.

[0038] In some embodiments of this application, please refer to Figure 2 and Figure 6 The first operating member 12 also includes a limiting plate 123, which is an annular plate and is connected to a button ring 121 and a rotating shaft 122. The button ring 121 is connected to the outer ring of the limiting plate 123, and the rotating shaft 122 is connected to the inner ring of the limiting plate 123. The limiting plate 123 is perpendicular to the axis of the first operating member 12 and is used to limit the sliding stroke of the second operating member 13 to prevent the second operating member 13 from being over-pressed and damaging the encoder 14 and the circuit board 16 below it.

[0039] In some embodiments of this application, please refer to Figure 6 The second operating member 13 includes a guide portion 134 extending along the axial direction of the first operating member 12, and the guide portion 134 and the limiting plate 123 are slidably connected along the axial direction of the first operating member 12, so that the second operating member 13, with the cooperation of the guide portion 134 and the limiting plate 123, can rotate synchronously with the first operating member 12 and transmit the rotation action to the input shaft 141 of the encoder 14, and can also slide relative to the first operating member 12 to perform a pressing operation on the encoder 14.

[0040] In some embodiments of this application, please refer to Figure 1 and Figure 2 The second operating member 13 also includes a pressing part 133, which is connected to the connecting part 131. The user can press the second operating member 13 by applying pressure to the pressing part 133. A reset member can be provided between the limiting plate 123 and the pressing part 133 to facilitate the pressing and reset of the pressing part 133.

[0041] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The elastic limiting member 15 includes an elastic member 151 and a ball 152. The abutting part is provided on the surface of the ball 152. The elastic member 151 always has the tendency to press the ball 152 against the inner circumferential surface of the button ring 121, so that the ball 152 abuts against the inner circumferential surface of the button ring 121. The ball 152 abuts against different recesses 1211 to produce a "click" sound and change the resistance, providing clear physical feedback to the user.

[0042] It should be noted that when the uneven inner circumferential surface of the knob 121 mates with the ball 152, the ball 152 transmits force to the elastic element 151, causing the elastic element 151 to expand and contract, thus allowing the knob 121 to rotate against the force of the ball 152. The elastic element 151 is in a pre-compressed state, and the elastic coefficient of the elastic element 151 can be set as needed, as long as it provides the user with appropriate damping and operational feedback when rotating the first operating element 12, without hindering the rotation of the first operating element 12.

[0043] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 6 The elastic limiting member 15 also includes a limiting cylinder 153, which extends radially along the ring 121. The elastic member 151 and the ball 152 are disposed inside the limiting cylinder 153. In the radial direction of the ring 121, the two ends of the elastic member 151 abut against the inner wall of the limiting cylinder 153 and the ball 152, respectively. The limiting cylinder 153 can protect and limit the elastic member 151 and the ball 152, so that the elastic member 151 can only extend and retract radially along the ring 121, and the ball 152 can only roll inside the limiting cylinder 153. Through the abutment and rolling contact between the ball 152 and the inner circumferential surface of the ring 121, the operation feedback can be improved while avoiding the ball 152 forming a large resistance to the rotation of the ring 121.

[0044] In some embodiments of this application, please refer to Figure 2 and Figure 6The limiting cylinder 153 is integrated with the seat 112 of the knob seat 11, which simplifies the assembly between the elastic limiting member 15 and the knob seat 11. The limiting cylinder 153 is located in the space formed by the knob ring 121, the limiting plate 123 and the seat 112, and the distance between the limiting plate 123 of the first operating member 12 and the seat 112 matches the size of the limiting cylinder 153, which can prevent the limiting cylinder 153 from interfering with the rotation of the first operating member 12.

[0045] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The knob assembly 1 also includes a circuit board 16. The main body 142 of the encoder 14 is mounted on the circuit board 16, which can transmit electrical signals to the circuit board 16 and transmit signals with the control component 3 in the operation control system through the circuit board 16.

[0046] Please see Figures 1 to 12 The second aspect of this application provides an operation control system, including the knob assembly 1 described in the above embodiments, and further including a display assembly 2 and a control assembly 3, such as... Figure 10 and Figure 11 As shown. The control component 3 is connected to the knob component 1 and the display component 2 respectively. The control component 3 can process the electrical signals transmitted by the knob component 1, and the display component 2 can display the adjustment page of the knob component 1, so that the user can observe and confirm the adjustment status.

[0047] It should be noted that this application uses the control component 3 to drive the display component 2 to dynamically update the adjustment page (such as function selection, parameter values, progress bars, status icons, etc.), so that users do not need to rely on the "click" sound or resistance change of the knob component 1 to confirm the condition status, and can intuitively confirm the operation result visually.

[0048] In some embodiments of this application, please refer to Figures 7 to 9 The display component 2 includes a pre-embedded box 21, a display screen 22, and an ambient light 23. The pre-embedded box 21 is used to fix the display component 2 as a whole on the electrical equipment. The display screen 22 and the ambient light 23 are both set in the pre-embedded box 21, and the ambient light 23 is arranged around the outer periphery of the display screen 22. When the display screen 22 displays an operation page (such as function selection, message notes, music playback, parameter adjustment, etc.), the change feedback can be achieved through the light change of the ambient light 23 arranged around the outer periphery of the display screen 22, so that the dynamic light effect of the ambient light 23 is linked with the display content of the display screen 22, creating an immersive interactive experience.

[0049] Specifically, the dynamic lighting effects of the ambient light 23 can include color changes, light intensity changes, breathing light effects, etc. When the display screen 22 displays the knob component 1 for function selection, the ambient light 23 can jump synchronously with the function page switching; when the current page is confirmed, the ambient light 23 can remain constantly lit; and when the display screen 22 is used to play music, the ambient light 23 can change its light according to the rhythm of the music, which can improve the intuitiveness and visual appeal of the interaction.

[0050] It should be noted that, due to the high cost of touch screens, the operation control system of this application is implemented through the knob component 1, which can reduce the cost of the operation control system. The knob component 1 is used as the core control component of the operation control system. Function selection and confirmation can be achieved through physical rotation and pressing. Moreover, the knob component 1 can rotate forward and backward to realize the forward and backward movement of the function. The operation is simple and avoids accidental touch operation. The adjustment page can be transmitted to the display screen 22 through the control component 3 for synchronous display, which can improve the intuitiveness of the interaction.

[0051] In some embodiments of this application, please refer to Figures 7 to 9 The display component 2 also includes a decorative film, which is attached to the outer surface of the ambient light 23 to enrich the appearance of the display component 2 and enhance its aesthetics. The decorative film is made of a light-transmitting material and can be used in conjunction with the ambient light 23 to provide different visual effects.

[0052] In some embodiments of this application, please refer to Figures 7 to 9 The decorative film can be a colored film or a textured film. The color of the colored film and the texture type of the textured film (such as wood grain, rock grain, etc.) can be determined according to the design style of the display component 2 and the electrical equipment, in order to enhance the product recognition of the display component 2 and the electrical equipment. There can be one or more decorative films to decorate the appearance of the display component 2, so that the displayed content blends with the decorative background and the lighting effect of the ambient light 23, enhancing the visual immersion.

[0053] In some embodiments of this application, please refer to Figures 7 to 9 The display component 2 includes a ring-shaped first decorative film 24 and a second decorative film 25. The first decorative film 24 is a colored film, and the second decorative film 25 is a textured film. The first decorative film 24 is attached to the outer surface of the ambient light 23 (i.e., the side facing the user), and the second decorative film 25 is attached to the outer surface of the first decorative film 24 and is arranged around the outer periphery of the display screen 22. The combination of the ambient light 23, the first decorative film 24, and the second decorative film 25 can create a high-end visual effect (such as retro, technological, minimalist, and fashionable visual effects), forming a unique product selling point and enhancing the product's market competitiveness.

[0054] In some embodiments of this application, please refer to Figures 7 to 9 The display component 2 also includes a transparent protective element 26. The embedded box 21 and the transparent protective element 26 enclose a mounting cavity for installing the display screen 22, ambient light 23, and decorative film. The transparent protective element 26 protects the display screen 22, ambient light 23, and decorative film, preventing dust or liquid from seeping into the mounting cavity and avoiding problems such as short circuits in the display screen 22, corrosion of the ambient light 23 circuit, or delamination of the decorative film. Specifically, the transparent protective element 26 can be made of glass, acrylic sheet, etc.

[0055] In the above embodiments, the display screen 22 is located at the center of the display component 2, and can be circular, elliptical, or polygonal in shape. The ambient light 23 and the decorative film are both annular structures concentrically arranged with the display screen 22, so that the display page of the display screen 22 is displayed in the central area of ​​the display component 2, thereby improving the visual effect of the display component 2. The resolution of the display screen 22 is preferably 1080P or higher, which can provide a clear display effect.

[0056] In the above embodiments of this application, when the encoder 14 has both rotation encoding and switching functions, it can simultaneously acquire the rotation and pressing actions of the second operating element 13, such as the EC11 encoder 14 with button function. When the encoder 14 only has rotation encoding function, a micro switch needs to be additionally provided to acquire the pressing operation signal of the second operating element 13.

[0057] In some embodiments of this application, the control component 3 includes a micro switch. The trigger end of the micro switch is located on the sliding stroke of the second operating member 13 or the encoder 14. When the second operating member 13 is pressed, the micro switch can be triggered by the movement of the second operating member 13 or the encoder 14, thereby realizing the adjustment confirmation of the knob component 1.

[0058] It should be noted that the trigger end of the micro switch can be set on the limit plate 123 or the encoder 14. The micro switch can be triggered by the second operating member 13 pressing the limit plate 123 or the encoder 14. Alternatively, the trigger end of the micro switch can be set between the encoder 14 and the circuit board 16. The micro switch can be triggered by the micro-motion or compression deformation of the encoder 14 (formed by the second operating member 13 pressing the encoder 14 downward). Both methods can achieve the purpose of this application.

[0059] It should be noted that the encoder 14 can achieve high-precision rotation angle detection and feedback, while the micro switch can confirm the current adjustment state. Through the cooperation of the encoder 14 and the micro switch, the operation signal of the knob assembly 1 can be accurately transmitted to the control assembly 3 and displayed through the display assembly 2.

[0060] In some embodiments of this application, please refer to Figure 11 The operation and control system also includes a voice interaction component 4 and a detection component 5. The voice interaction component 4 facilitates direct voice communication with the user, allowing the user to input voice commands, realize AI intelligent interaction, and simplify the user's operation and adjustment process. The detection component 5 is used to detect the user's position. Both the voice interaction component 4 and the detection component 5 are connected to the control component 3. When the detection component 5 detects that the user is approaching, it can send a signal to the control component 3 to power on the operation and control system, which can prevent the display component 2 from being constantly lit and reduce the energy consumption of the operation and control system.

[0061] It should be noted that the voice interaction component 4 can directly convert user voice commands (such as "function switch", "turn up volume", "turn on air conditioner" etc.) into control signals through voice recognition technology (such as automatic voice recognition), eliminating the need for manual operation of the knob component 1 and improving interaction efficiency. The detection component 5 may include detection elements such as radar sensors and infrared sensors. By monitoring the user's position, it sends a power signal to the control component 3 only when the user is detected approaching, triggering the display component 2 (such as display screen 22 and ambient light 23) to light up; it automatically turns off the power after the user leaves, avoiding unnecessary energy consumption caused by the display component 2 remaining constantly lit.

[0062] Please see Figures 1 to 12 The third aspect of this application provides an electrical device, including the operation control system described in the above embodiments, and further including a door body 6. A knob assembly 1 and a display assembly 2 are disposed on the door body 6, which can adjust and display the functional mode and operating parameters of the electrical device. There is a preset distance between the knob assembly 1 and the display assembly 2, so that the knob assembly 1 and the display assembly 2 are set separately, avoiding the situation where the display screen 22 is too small to be easy to observe when the knob assembly 1 and the display assembly 2 are integrated.

[0063] This application places the knob assembly 1 on the outside of the display assembly 2, so that the size of the display assembly 2 is not limited by the knob assembly 1. When the user operates the knob assembly 1, the operation page can be clearly displayed through the display assembly 2, avoiding visual interference between the knob assembly 1 and the display assembly 2.

[0064] Meanwhile, the separate design of the knob assembly 1 and the display assembly 2 facilitates independent maintenance and allows for individual replacement of parts, reducing long-term operating costs. The flexible placement of the knob assembly 1 and the display assembly 2 also makes it easier to meet product design requirements.

[0065] In the above embodiments, the electrical equipment can be a refrigerator, air conditioner, washing machine, etc. The corresponding functions can be selected and parameters can be adjusted by the knob component 1, and the functions can be displayed by the display component 2 (such as room temperature, mode switching, message notes, music playback, etc.), which can improve the user's operation and interaction experience.

[0066] Please see Figures 1 to 12 In some embodiments of this application, the operation process of the operation control system is as follows: Step 1: When the detection component 5 detects the user approaching, or when the user operates the knob component 1, the control component 3 receives a signal to power on the operation control system, and the ambient light 23 lights up. Step 2: When rotating the knob assembly 1, the encoder 14 transmits the rotation signal to the control assembly 3, the display screen 22 displays the function selection page, and the ambient light 23 jumps synchronously. Step 3: Press the second operating element 13 to confirm the function. The confirmation signal is transmitted to the control component 3 through the encoder 14 or micro switch and displayed on the display screen 22. Step 4: Display screen 22 shows the current function page, and ambient light 23 remains on; Step 5: Press and hold (e.g., for three seconds) the second operation item 13 to exit the current function; Step Six: The user rotates knob assembly 1 to make the next adjustment, or moves away from the operation control system. After the operation control system has not been used for a long time (such as three minutes), the power is turned off and the screen is turned off, ending the operation process.
