Description

Technical Field

[0001] This utility model relates to the field of menu knob technology, specifically a menu knob with a push-button roller and a portable power supply device. Background Technology

[0002] With the intelligent development of portable power supply devices (such as power banks, outdoor energy storage devices, rechargeable tools, etc.), their functions are becoming increasingly complex. Users need to adjust various parameters (such as output power, charging mode, device status display, etc.) through the menu system. Traditional menu interaction solutions mainly rely on physical button combinations to achieve selection and confirmation functions.

[0003] To enable multi-level menu operation, devices typically need to have multiple independent buttons (such as "up / down / left / right" directional keys, "confirm / return" keys, etc.). This design results in a crowded device panel layout. Especially in miniaturized devices (such as handheld power supplies), dense buttons can significantly compress the space of other functional modules (such as displays and interfaces), affecting the overall structural compactness. Moreover, mechanical buttons are prone to wear and tear and poor contact after long-term use. Utility Model Content

One end of the tactile adjustment sealing ring 4 contacts the roller cover 6, and the other end contacts the roller cover pressure plate 2.

[0037] By rotating the roller 5, the magnet 3 is driven to rotate. At this time, the magnetic field generated by the magnet 3 changes, which in turn transmits a signal to the Hall chip to realize the menu selection function. The sealing ring 4 is adjusted by touch to contact the roller cover 6 and the roller cover pressure plate 2 to further seal the device and prevent liquid from seeping into the Hall chip 16.

[0038] Specifically, such as Figure 1 as well as Figure 3 As shown, a roller cover pressure plate 2 is provided at the position of the corresponding feel adjustment sealing ring 4 of the decorative cover 1. The roller cover pressure plate 2 is located between the decorative cover 1 and the roller 5. A through hole is provided on the roller cover pressure plate 2, and a threaded groove is provided at the position of the corresponding through hole of the roller cover 6.

[0039] Align the through hole 1 on the roller cover pressure plate 2 with the threaded groove 1 on the roller cover 6, and fix and lock the roller cover pressure plate 2 with screws. Adjust the damping of the roller 5 rotation by adjusting the compression of the sealing ring 4 by hand.

[0040] Specifically, such as Figure 1 and Figure 3 As shown, the transmission component includes a bearing 8 and a shaft 9. The bearing 8 is installed at the end of the roller 5 away from the hand feel adjustment sealing ring 4. One end of the shaft 9 is installed inside the bearing 8, and the other end is connected to the pressing component.

[0041] A locking block is provided at the end of shaft 9, which passes through bearing 8 and locks it in place.

[0042] Specifically, such as Figure 1 and Figure 3 As shown, the pressing component includes a button contact 12, which is located at the end of the shaft 9 away from the roller 5. A button spring 13 is sleeved on the button contact 12 for resetting the button contact 12. A through hole 2 is provided on the button contact 12, and a threaded groove 2 is provided at the corresponding position of the through hole 2 on the shaft 9.

[0043] Specifically, such as Figure 1 as well as Figure 4 As shown, the sealing component includes a first sealing gasket 10, which is disposed between the shaft 9 and the button contact 12. A sealing pressure plate 11 is disposed between the first sealing gasket 10 and the button contact 12. A second sealing gasket 7 is disposed at the end of the roller cover 6 away from the decorative cover 1. The Hall chip 16 is located between the roller cover 6 and the second sealing gasket 7. A set of through holes 3 is provided on the first sealing gasket 10, and multiple sets of through holes 4 are provided on the sealing pressure plate 11. A set of through holes 4 is aligned with the through holes 3.

[0044] Place the roller 5 into the roller cover 6, pass the shaft 9 through the roller cover 6 and fasten it onto the bearing 8, then put the first sealing gasket 10 on the shaft 9, press the first sealing gasket 10 with the sealing pressure plate 11, then put the button contact 12 on the end face of the shaft 9, and fix and lock it by passing the screw through the through hole two and cooperating with the threaded groove two, and then put the button spring 13 on the button contact 12.

[0045] By screwing through the through holes three and four and engaging with the threaded groove three on the roller cover 6, the first sealing gasket 10 and the sealing pressure plate 11 are fixed and locked. The first sealing gasket 10 seals the top of the roller cover 6. By setting the second sealing gasket 7 on the contact surface of the roller cover 6 on the whole machine, the device is sealed to the whole machine, which further increases the sealing effect of the device and seals the Hall chip 16 to ensure stable signal transmission.

[0046] A portable power supply device includes the aforementioned menu knob with a push-button roller.

[0047] The portable power supply device has a button inside. The pressing component is located above the button. When the roller 5 is pressed in the radial direction, the roller 5 drives the transmission component to press the pressing component in the axial direction of the roller 5, thereby driving the pressing component to press the button.

[0048] The specific details of this plan are as follows:

[0049] First, install the bearing 8 inside the roller 5. Then, install the magnet 3 into the Hall chip 16 using waterproof adhesive. Next, fit the tactile adjustment sealing ring 4 into the sealing groove 14. Then, place the roller 5 into the roller cover 6. Pass the shaft 9 through the roller cover 6 and fasten it onto the bearing 8. Then, put the first sealing gasket 10 onto the shaft 9 and press it down with the sealing pressure plate 11. Then, fit the button contact 12 onto the end face of the shaft 9 and fix it by passing a screw through the through hole two and engaging with the threaded groove two. Then, fit the button spring 13 onto the button contact 12 and connect the through hole one on the roller cover pressure plate 2 to the... Align the threaded grooves on the roller cover 6 and secure the roller cover pressure plate 2 with screws. At this time, the damping of the roller 5 rotation can be adjusted by feeling the compression of the sealing ring 4. Then, place the second sealing gasket 7 on the whole machine housing and install the roller cover 6 into the whole machine. The second sealing gasket 7 can be pressed onto the surface of the roller cover 6 and adhered to the roller cover 6 with screws to ensure its sealing. At this time, the Hall chip 16 is located between the roller cover 6 and the second sealing gasket 7, and the button is located directly below the button contact 12, which can also seal and waterproof the Hall chip 16. Finally, snap the decorative cover 1 onto the roller cover 6.

[0050] In use, this device uses a Hall chip 16 facing a magnet 3. Rotating the roller 5 causes the magnet 3 to rotate, changing its magnetic field and transmitting a signal to the Hall chip to enable menu selection. The button is located directly below the button contact 12. When the roller 5 is pressed, it moves the button contact 12 downwards via the shaft 9, pressing the button to confirm the menu. When the button is deactivated, the button spring 13 returns to its original position. This design eliminates the need for multiple independent buttons, resulting in a smaller overall space requirement, a compact structure, easy installation, and improved production efficiency. The device seals one end of the roller 5 with a first sealing gasket 10 and the other end with a tactile adjustment sealing ring 4. The Hall chip 16 is separated from the magnet 3 and sealed by a second sealing gasket 7, isolating the roller 5 from the pressing component and the second sealing gasket 7. Menu selection is controlled via contactless signal transmission, effectively preventing poor contact due to wear from mechanical buttons over time and preventing short circuits or malfunctions caused by liquids or impurities seeping into the button gaps.
