Description

Technical Field

[0001] This utility model relates to the field of knob technology, and in particular to a knob device that can automatically raise and lower. Background Technology

[0002] In the field of home appliances, such as washing machines, dryers, air conditioners, and dishwashers, users typically need to use knobs to select modes, set temperatures, and adjust fan speeds. Currently, the knob modules of most home appliances on the market adopt a fixed installation structure, meaning that the knob and the control module behind it protrude directly and fixedly from the main unit panel.

[0003] The protruding knobs disrupt the flatness and integrity of the main unit panel, appearing quite abrupt and reducing the product's premium and quality feel. Furthermore, the exposed knobs are easily touched or bumped, reducing their lifespan and posing certain safety hazards.

[0004] In existing technology, a lifting device drives the knob to move along its axis, so that the knob retracts to the inside of the main unit panel when not in use and extends to the outside of the main unit panel when in use. However, the existing driving method results in poor smoothness and stability of the knob during the extension and retraction process, which may lead to jamming, reducing the premium feel of the product and the user experience.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-5 As shown, this embodiment provides an automatically lifting knob device. The automatically lifting knob device includes a knob module 1, a base cover 2, and a lifting mechanism 3. The lifting mechanism 3 is located on the side of the base cover 2 facing the knob module 1, which can reduce the overall size of the automatically lifting knob device and save installation space. The lifting mechanism 3 includes a drive motor 31, a transmission assembly 32, a threaded sleeve 33, and a screw 34. The output shaft of the drive motor 31 is connected to the threaded sleeve 33 through the transmission assembly 32 to drive the threaded sleeve 33 to rotate along its central axis. The screw 34 is threadedly connected to the threaded sleeve 33, and the knob module 1 is fixedly connected to the screw 34. The rotation of the threaded sleeve 33 along its central axis drives the screw 34 to move axially, thereby causing the knob module 1 to move synchronously with the screw 34, realizing the extension or retraction of the knob module 1, so as to adjust the position of the knob module 1 according to the user's needs. The screw 34 is driven to move axially by the rotation of the threaded sleeve 33, ensuring that the screw 34 moves only in the axial direction and preventing jamming. This improves the smoothness and stability of the knob module 1 during movement. The range of axial movement of the screw 34 is set according to specific circumstances, and this embodiment does not limit it. The specific structure of the knob module 1 is based on existing technology and will not be described in detail here.

[0034] Optionally, the transmission assembly 32 includes a first gear 321 and a second gear 322, which are meshed together. A drive motor 31 is connected to the first gear 321, and a threaded sleeve 33 is connected to and coaxially arranged with the second gear 322. The transmission via the first gear 321 and the second gear 322 makes the transmission smoother, improves the stability of the knob module 1 during movement, and also makes the overall structure of the transmission assembly 32 more compact, saving installation space.

[0035] Specifically, the transmission assembly 32 also includes a third gear 323, which is disposed between the first gear 321 and the second gear 322, and the first gear 321 and the second gear 322 are meshed and connected through the third gear 323. The third gear 323 is rotatably connected to the bottom cover 2 via a rotating shaft, improving the smoothness of the transmission of the transmission assembly 32. A threaded sleeve 33 is fixedly connected to the side of the second gear 322 facing the knob module 1.

[0036] Optionally, the bottom cover 2 is provided with a mounting groove 21, in which the first gear 321 and the second gear 322 are both disposed. The drive motor 31 is disposed on the side of the first gear 321 facing away from the bottom cover 2. This arrangement can reduce the overall length of the automatically lifting knob device along the axial direction of the screw 34, saving installation space.

[0037] Specifically, the mounting groove 21 includes a first mounting portion and a second mounting portion, which are connected. The first mounting portion 321 and the third mounting portion 323 are located in the first mounting portion, the second mounting portion has a circular cross-section along the axial direction of the screw 34, and the second gear 322 and the threaded sleeve 33 are located in the second mounting portion.

[0038] Optionally, the automatically lifting knob device also includes a bearing 4, and the threaded sleeve 33 is rotatably connected to the inner wall of the mounting groove 21 via the bearing 4. The bearing 4 rotatably connects the threaded sleeve 33 to the bottom cover 2, improving the smoothness of the rotation of the threaded sleeve 33, thereby enhancing the stability of the knob module 1 during movement. Specifically, the inner ring of the bearing 4 is interference-fitted onto the outer wall of the threaded sleeve 33, and the outer ring of the bearing 4 is interference-fitted with the inner wall of the second mounting portion.

[0039] Optionally, the automatically lifting knob device also includes a fixing member 5, which is fixedly connected to the screw 34, and the knob module 1 is fixedly connected to the fixing member 5. The fixing member 5 facilitates connection between the fixing member 5 and the screw 34. Specifically, the fixing member 5 has a ring-shaped structure. The fixing member 5 is sleeved on the end of the screw 34 away from the bottom cover 2. A through hole is provided on the fixing member 5, and a threaded hole corresponding to the through hole is provided on the knob module 1. A screw is passed through the through hole and threaded into the threaded hole, thereby fixing the knob module 1 to the fixing member 5.

[0040] Furthermore, the fixing member 5 and the screw 34 are detachably connected, facilitating the replacement of different types of knob modules 1. When it is necessary to replace the knob module 1, only the fixing member 5 needs to be removed, simplifying operation and enabling the lifting mechanism 3 to accommodate different types of knob modules 1, thus improving the applicability of the lifting mechanism 3. Specifically, the fixing member 5 is interference-fitted onto the end of the screw 34 furthest from the bottom cover 2. In other embodiments, the fixing member 5 and the screw 34 can also be fixed by screw connection or snap-fit.

[0041] Optionally, the automatically lifting knob device also includes a housing 6, which covers the fixing member 5 and the lifting mechanism 3 and is connected to the bottom cover 2. By providing the housing 6, the overall structure of the automatically lifting knob device becomes more aesthetically pleasing. Simultaneously, the housing 6 protects the lifting mechanism 3 and the fixing member 5 from external dust and water contamination. Specifically, the automatically lifting knob device also includes multiple fixing screws 8, which detachably connect the housing 6 to the bottom cover 2, facilitating the assembly of the automatically lifting knob device.

[0042] Optionally, the fixing member 5 is slidably connected to the housing 6 along the axial direction of the screw 34, and the housing 6 guides the fixing member 5 to ensure that the screw 34 can move along its axial direction when the threaded sleeve 33 rotates.

[0043] Specifically, a guide protrusion 51 is provided on the outer wall of the fixing member 5, and a guide groove 61 corresponding to the guide protrusion 51 is provided on the inner wall of the outer shell 6.
