Description

Technical Field

[0001] This utility model belongs to the field of controller technology, and in particular relates to a dual-knob control device. Background Technology

[0002] Existing conventional controllers offer limited control, allowing only a single controller to manage a single device, preventing simultaneous operation of multiple devices. Their functionality is limited, inconvenient, and unable to handle complex control functions. Therefore, a multi-functional controller has been designed to connect to multiple devices and control them simultaneously. Patent CN117348684A discloses a dual-knob controller that, after connecting multiple devices, allows for different controls of a single device via an inner and outer knob. For example, the inner and outer knobs can be used to adjust the brightness and color temperature of a smart light fixture. However, this dual-knob controller uses an inner and outer knob design. Users must rely on the friction between their fingers and the inner knob's surface to rotate it, which is inconvenient and increases the risk of accidentally pressing buttons near the inner knob, leading to unnecessary problems. Utility Model Content

[0003] This utility model provides a dual-knob control device, which aims to solve the technical problem that existing multi-functional controllers use an inner and outer knob design. When operating the inner knob, users need to rely on the friction between their fingers and the surface of the inner knob to rotate it, which is inconvenient. In addition, it is easy to accidentally touch the buttons near the inner knob, causing unnecessary trouble.

[0037] refer to Figures 1-5 This application provides a dual-knob control device, comprising:

[0038] The base 100 includes a lower base 110 and an upper base 120 disposed on the lower base 110;

[0039] A first knob assembly 200 is disposed on the upper base 120;

[0040] A second knob assembly 300 is disposed on the upper base 120, and the second knob assembly 300 and the first knob assembly 200 are arranged vertically; and

[0041] Screen assembly 400 is mounted on the upper base 120.

[0042] The base 100 provides support for the first knob assembly 200, the second knob assembly 300, and the screen assembly 400.

[0043] In this design, the second knob assembly 300 and the first knob assembly 200 are arranged vertically. For example, the second knob assembly 300 may be located above the first knob assembly 200, where "above" and "below" are relative concepts; or the first knob assembly 200 may be located above the second knob assembly 300, where "above" and "below" are relative concepts. The first knob assembly 200 and the second knob assembly 300 do not contact each other. Alternatively, in the dual-knob control device, from top to bottom, the first knob assembly 200 and the second knob assembly 300 are partially staggered to prevent the user from accidentally operating the second knob assembly 300 while operating the first knob assembly 200, and vice versa.

[0044] By operating the screen component 400, the user can control at least one device, such as a smart lamp. Next, by operating the first knob component 200, the user can adjust a first function of the device, and by operating the second knob component 300, the user can adjust a second function of the device, such as adjusting the color temperature and brightness of the smart lamp.

[0045] In some implementations, users can control and connect multiple devices by operating the screen component 400, such as smart lights, smart air conditioners, smart sofas, and smart curtains. Then, after selecting the smart home device to be controlled, the user can perform multi-functional adjustments to that smart home device by operating the first knob component 200 and the second knob component 300.

[0046] It should be noted that this application aims to protect the composition and connection relationships of the above-mentioned hardware structure, rather than the control logic / control method.

[0047] In this application, when the user operates the first knob assembly 200 and the second knob assembly 300, since the second knob assembly 300 and the first knob assembly 200 are arranged vertically, the user can rotate the first knob assembly 200 and the second knob assembly 300 by hand, making the operation very simple and quick. The screen assembly 400 is not on the same plane as the rotation surface of the first knob assembly 200 and the second knob assembly 300, so the screen assembly 400 will not be accidentally operated when operating the first knob assembly 200 and the second knob assembly 300, thereby avoiding unnecessary trouble.

[0048] refer to Figure 1 and Figure 5 In some specific embodiments of this application, the first knob assembly 200 includes a first bearing 210 sleeved on the upper base 120 and a first knob 220 externally disposed on the first bearing 210.

[0049] The first bearing 210 is mounted on the upper base 120, and the first knob 220 is mounted on the first bearing 210. Specifically, the inner ring of the first knob 220 is in partial or complete contact with the outer ring of the first bearing 210. When the first knob 220 rotates, the first bearing 210 helps the first knob 220 to rotate smoothly.

[0050] In this embodiment, the user can adjust the first function of the device by rotating the first knob 220, which is facilitated by the first bearing 210. For example, by rotating the first knob 220, the user can adjust the color temperature of the smart lamp. When the first knob 220 is rotated in the forward direction, the color temperature of the smart lamp becomes cooler, and when the first knob 220 is rotated in the reverse direction, the color temperature of the smart lamp becomes warmer.

[0051] refer to Figure 1 and Figure 5 In some specific embodiments of this application, the second knob assembly 300 includes a second bearing 310 sleeved on the upper base 120 and a second knob 320 externally disposed on the second bearing 310, wherein the second knob 320 and the first knob 220 are arranged vertically.

[0052] The second bearing 310 is mounted on the upper base 120, and the second knob 320 is mounted on the second bearing 310. Specifically, the inner ring of the second knob 320 is in partial or complete contact with the outer ring of the second bearing 310. When the second knob 320 rotates, the second bearing 310 helps the second knob 320 to rotate smoothly.

[0053] In this embodiment, the user can adjust the second function of the device by rotating the second knob 320, which is facilitated by the second bearing 310. For example, by rotating the second knob 320, the user can adjust the brightness of the smart lamp. When the second knob 320 is rotated in the forward direction, the brightness of the smart lamp increases, and when the second knob 320 is rotated in the reverse direction, the brightness of the smart lamp decreases.

[0054] In this embodiment, the second knob 320 is located above, and the first knob 220 is located below. Specifically, the upper base 120 of the base 100 is provided with a first protrusion and a second protrusion disposed on the first protrusion. The second protrusion is located above, and the first protrusion is located below. The first knob 220 is sleeved on the first protrusion, and the second knob 320 is sleeved on the second protrusion. When the user operates the first knob 220 and the second knob 320, since the second knob 320 and the first knob 220 are arranged vertically, the user can rotate the first knob 220 and the second knob 320 by hand, making the operation very simple and quick. The screen assembly 400 is not on the same plane as the rotation surfaces of the first knob 220 and the second knob 320, so the screen assembly 400 will not be accidentally operated when operating the first knob 220 and the second knob 320, thus avoiding unnecessary trouble.

[0055] In some implementations, the rotating surface of the second knob 320 can be designed with a cutout. When operating blindly, the user can determine whether they are operating the first knob 220 or the second knob 320 by the feel of touching the first knob 220 and the second knob 320, thus facilitating the operation of both knobs. Additionally, the cutout design also adds an aesthetic appeal.

[0056] refer to Figure 5 In some specific embodiments of this application, the dual-knob control device further includes:

[0057] The first circuit board is disposed inside the lower base 110;

[0058] A charging element is disposed inside the lower base 110, and the charging element is connected to the first circuit board; and

[0059] A power supply element is disposed inside the lower base 110 and / or the upper base 120, and the power supply element is connected to the first circuit board.

[0060] The base 100 has an internal cavity. Specifically, the upper base 120 and the lower base 110 have internal cavities. In some embodiments, the cavity of the lower base 110 is used to accommodate the first circuit board and the charging element, the cavity of the lower base 110 is used to accommodate the charging element, and the cavities of the lower base 110 and the upper base 120 are used to accommodate the power supply element.

[0061] The first circuit board is a PCB board, which controls the charging and power supply components.

[0062] The charging element is equipped with a charging interface, and the lower base 110 is equipped with a through hole, through which the charging interface is connected.

[0063] The power supply element is a rechargeable battery 510, which provides power to the entire dual-knob control device. The battery 510 can be charged when an external charging cable is inserted into the charging port.

[0064] refer to Figure 1 and Figure 5 In some specific embodiments of this application, the screen assembly 400 includes:

[0065] A second circuit board 410 is disposed above the upper base 120;

[0066] The button bracket 420 is disposed on the second circuit board 410; and

[0067] Electronic screen 430 is mounted on the button bracket 420.

[0068] The second circuit board 410 is a PCBA board, which controls the electronic screen 430.

[0069] The electronic screen 430 is mounted on the button bracket 420, which provides support for the electronic screen 430.

[0070] The electronic screen 430 is equipped with multiple electronic buttons. For example, the surface of the electronic screen 430 is circular, and an electronic button is set at every 90° interval, for a total of four electronic buttons. These four electronic buttons correspond to four devices. By clicking a certain electronic button, the user can control and connect the corresponding device.

[0071] refer to Figures 1-5 In some specific embodiments of this application, the second circuit board 410 is provided with a plurality of first through holes 411, the button bracket 420 is provided with a plurality of second through holes 421, and the upper base 120 is provided with a plurality of grooves 121. By means of screws 440 passing through the second through holes 421 and the first through holes 411 in sequence and being inserted into the grooves 121, the button bracket 420, the second circuit board 410 and the upper base 120 are fixedly connected.

[0072] For example, the second circuit board 410 has four first through holes 411 at regular intervals, the button bracket 420 has four second through holes 421 at regular intervals, and the upper base 120 has four grooves 121 at regular intervals. Four screws 440 are sequentially passed through the second through holes 421 and the first through holes 411 and inserted into the grooves 121, thus securing the button bracket 420, the second circuit board 410, and the upper base 120 together.

[0073] refer to Figure 5In some specific embodiments of this application, the screen assembly 400 further includes a screen adhesive 450 attached to the back of the electronic screen 430, the screen adhesive 450 being located between the electronic screen 430 and the button bracket 420. By providing the screen adhesive 450, the electronic screen 430 can be fixed and a certain degree of cushioning protection can be achieved.

[0074] In some embodiments, the electronic screen 430 is circular, and the screen adhesive 450 is circular to match the electronic screen 430, so that the back of the electronic screen 430 is covered with the screen adhesive 450, thereby achieving the overall effect of the electronic screen 430.

[0075] In some specific embodiments of this application, the bottom surface of the lower base 110 is set at an inclined angle. When the dual-knob control device is fixed on a horizontal plane, because the bottom surface of the lower base 110 is set at an inclined angle, the entire dual-knob control device is set at an inclined angle, and the screen assembly 400 will be biased towards the user, specifically the electronic screen 430 will be biased towards the user, thereby helping the user to operate.

[0076] refer to Figure 5 In some specific embodiments of this application, the bottom surface of the lower base 110 is provided with an anti-slip pad 600. By providing the anti-slip pad 600, the deviation of the dual-knob control device during use is prevented.

[0077] In some specific embodiments of this application, the bottom surface of the lower base 110 is provided with a receiving groove, and the anti-slip pad 600 is disposed in the receiving groove. By providing the receiving groove, the anti-slip pad 600 is disposed in the receiving groove, thus preventing the anti-slip pad 600 from protruding from the lower base 110.
