Description

Technical Field

[0001] This utility model relates to the field of intelligent electrical appliance control accessories technology, and in particular to an outdoor knob. Background Technology

[0002] Currently, the knobs used for controlling smart appliances are encoder knobs. Traditional encoder knobs have a mechanical connection between the knob and the encoder. Outdoor use often results in short circuits in the encoder or PCBA (Printed Circuit Board Assembly) due to rain or water exposure, leading to knob failure. A related technology offers a knob that completely isolates waterproof electronic components and moving parts, connects them via a magnetic field, and uses sealing gaskets between the waterproof electronic components and moving parts, achieving better waterproof sealing for the entire knob.

[0003] However, when the knob needs to integrate functions such as display and push switch, its installation structure is relatively complex. After the encoder knob and the display screen are stacked, the product size and thickness become larger, which cannot meet the size requirements of small outdoor products. In addition, the internal space of the encoder knob is limited, making it difficult to integrate the push switch inside the knob. Or, if the push switch is integrated, it may cause the knob to have a large degree of play and wobble, resulting in a poor user experience. Utility Model Content

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] Please refer to Figures 1 to 5This embodiment provides an outdoor knob, including: a housing 1, a display component 2, a base 3, and an encoder assembly arranged parallel and coaxially. The housing 1 is fitted onto the display component 2, the base 3, and the encoder assembly. The housing 1 is rotatable about its own axis, and the upper surface of the display component 2 is flush with the upper edge of the housing 1. The encoder assembly includes a PCBA circuit board 4, a ribbon cable 5, a magnetic ring 6, and a rotating shaft 7. The PCBA circuit board 4 is disposed between the display component 2 and the base 3. The length direction of the ribbon cable 5 is parallel to the axis of the housing 1, and one end of the ribbon cable 5 is fixed. The other end of the ribbon cable 5 extends out of the lower edge of the outer shell 1 and is fixedly connected to the PCBA circuit board 4. The rotating shaft 7 is fixedly connected to the outer shell 1 and is provided with a mounting groove 72. The magnetic ring 6 is set in the mounting groove 72. The center of the base 3 is provided with a through hole. The outdoor knob also includes a support shaft 8, which is fixedly connected to the through hole. The center of the support shaft 8 is provided with a clearance groove 81. A push button switch 9 is provided on the side of the PCBA circuit board 4 near the base 3. The push button switch 9 is set in the clearance groove 81 and can abut against the bottom of the clearance groove 81.

[0039] By coaxially stacking and encapsulating the housing 1, display component 2, PCBA circuit board 4, magnetic ring 6, and base 3 within the housing 1, the thickness of the knob is limited only by the individual layers, thus reducing the thickness of the outdoor knob. Simultaneously, by setting a support shaft 8, which is fixedly connected to a through hole, and having a clearance groove 81 at its center, a push-button switch 9 is located on the side of the PCBA circuit board 4 near the base 3. The push-button switch 9 is positioned within the clearance groove 81 and can abut against the bottom of the groove, allowing it to be integrated into the axis of the rotating shaft 7. This ensures the pressing stroke of the push-button switch 9 while saving installation space and reducing the impact of adding the push-button switch 9's functionality on the thickness of the outdoor knob.

[0040] Specifically, the outer shell 1 is made of plastic and coated with a three-proof paint to ensure the sealing performance of the outdoor knob.

[0041] Furthermore, the encoder assembly integrates a Hall sensor on the PCBA circuit board 4 and a magnetic ring 6 to sense the output signal, which completely isolates the electronic components such as the PCBA circuit board 4 that require waterproofing and the moving parts such as the rotating shaft 7. The signal is connected through electromagnetic induction, which facilitates the sealing of the electronic components. This allows the entire outdoor knob to have good waterproof sealing performance and be suitable for outdoor use.

[0042] Alternatively, please refer to Figure 2A first sealing layer 10 is provided between the mounting groove 72 and the magnetic ring 6; and / or, a second sealing layer 11 is provided between the PCBA circuit board 4 and the display component 2 and the base 3. Preferably, the first sealing layer 10 and / or the second sealing layer 11 are potting adhesive sealing layers. With this configuration, the sealing layer is tightly fitted to the mounting groove 72 and other structures through potting adhesive sealing, ensuring that all electronic components are sealed and achieving a waterproof effect. Moreover, the liquid adhesive has a small thickness after curing, further reducing the size of the outdoor knob.

[0043] In other embodiments, the first sealing layer 10 and / or the second sealing layer 11 may also be a sealing gasket.

[0044] Alternatively, please refer to Figure 3 The outdoor knob also includes a positioning spring 12, which is fixedly connected to the bottom of the base 3. The positioning spring 12 has spaced elastic protrusions 121. Multiple positioning teeth 71 are spaced along the circumference of the end face of the rotating shaft 7 near the positioning spring 12. When the rotating shaft 7 rotates, the elastic protrusions 121 can abut against the positioning teeth 71 and undergo elastic deformation. This arrangement provides a clear tactile feedback and damping during the rotation of the outer casing 1 through the elastic engagement of the elastic protrusions 121 and the positioning teeth 71.

[0045] Specifically, the positioning spring 12 is riveted to the bottom of the base 3. By integrating the positioning spring 12 onto the base 3 and the positioning tooth 71 onto the rotating shaft 7, the control feel and long-term sealing reliability of the knob are further improved without increasing the thickness or compromising the waterproof integrity.

[0046] Optionally, one of the outer peripheral surface of the rotating shaft 7 and the inner wall of the outer casing 1 is provided with multiple locking blocks spaced apart along its own circumference, and the other of the outer peripheral surface of the rotating shaft 7 and the inner wall of the outer casing 1 is provided with multiple locking grooves spaced apart along its own circumference. The multiple locking blocks are correspondingly disposed in the multiple locking grooves. Through the circumferential fitting structure of the locking blocks and locking grooves, the rotational torque of the outer casing 1 can be directly and evenly transmitted to the rotating shaft 7 without the need for additional screws or keys. This saves radial and axial space, reduces the thickness of the outdoor knob, and avoids the waterproofing risks caused by loose screws.

[0047] Alternatively, please refer to Figure 1 The inner wall of the through hole of the base 3 is provided with a first anti-rotation part 31, and the outer wall of the support shaft 8 is provided with a second anti-rotation part 82. The first anti-rotation part 31 and the second anti-rotation part 82 are engaged to fix the relative position of the base 3 and the support shaft 8. Specifically, the first anti-rotation part 31 consists of two symmetrically arranged protrusions, and the second anti-rotation part 82 consists of two grooves corresponding to the first anti-rotation part 31. The two protrusions are engaged in the two grooves respectively. By engaging the protrusions and grooves, relative rotation between the support shaft 8 and the base 3 around the axis is prevented.

[0048] Furthermore, the through hole is a recessed through hole, and the bottom of the relief groove 81 is flush with the lower edge of the recessed through hole wall. The outdoor knob also includes a fixing plate 13 and a connector 14. The fixing plate 13 is coaxially disposed on the side of the rotating shaft 7 away from the magnetic ring 6. The fixing plate 13 includes an annular baffle 131 and a connecting part 132 fixedly connected to the inner ring of the annular baffle 131. The connecting part 132 is correspondingly disposed with the first anti-rotation part 31. The connector 14 passes through the connecting part 132 and the first anti-rotation part 31 in sequence. Specifically, the fixing plate 13 is detachably connected to the outer component. With this configuration, the rotating shaft 7, magnetic ring 6, and positioning spring 12 are positioned between the fixing plate 13 and the base 3, avoiding axial movement. At the same time, the fixing plate 13 is connected to the base 3 and the outer component respectively, eliminating the risk of the base 3 rotating when the knob housing 1 rotates, and ensuring the positioning accuracy of the outdoor knob.

[0049] Alternatively, please refer to Figure 1 The display assembly 2 includes a display bracket 21, a display film 22, and a cover plate 23. The display film 22 is fixedly connected between the display bracket 21 and the cover plate 23. The output terminal of the PCBA circuit board 4 is connected to the signal transmission terminal of the display bracket 21, so that the display assembly 2 can display the data fed back by the PCBA circuit board 4. The display film 22 is clamped between the display bracket 21 and the cover plate 23 to form a screwless ultra-thin stack. The PCBA is directly connected to the signal terminal of the display bracket 21 through the ribbon cable 5 to realize direct data transmission. The cover plate 23 is flush with the upper edge of the outer shell 1 and is integrally sealed with glue, which not only ensures the ultra-thin thickness but also provides a waterproof and transparent window for the LED light source. The whole machine does not require additional wiring harnesses or brackets, and the assembly is completed in one step.

[0050] In this embodiment, the display component 2 is an LED display (light-emitting diode display). In other embodiments, the display component 2 can also be a TFT display (Thin Film Transistor Liquid Crystal Display), an OLED display (Organic Light-Emitting Diode), etc. Users can select the type of display component 2 and replace it according to their needs without changing the overall structure of the outdoor knob, making the device highly adaptable.

[0051] Optionally, the outer surface of the housing 1 is provided with anti-slip texture. This design increases the surface friction of the housing 1, reducing the effort required for manual rotation and extending the lifespan of the knob. In this embodiment, the anti-slip texture is a striped pattern for ease of processing. In other embodiments, the anti-slip texture can also be a mesh pattern.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
