DETAILED DESCRIPTION
[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0018] Combined with Figure 1 To Attachment Figure 5 As shown, a push-type encoder knob includes a mounting base 10, a knob member 20, an upper cover plate 31, and a lower cover plate 32. Figure 5As shown, the mounting base 10 is provided with an upper mounting area 101 and a lower mounting area 102. The lower mounting area 102 is provided with a key switch 40, which is specifically a long-stroke silent key switch. A magnetic ring 50 is provided in the upper mounting area 101. The upper cover plate 31 and the lower cover plate 32 are respectively covered on the upper mounting area 101 and the lower mounting area 102. The lower cover plate 32 encapsulates the key switch 40 in the lower mounting area 102 of the mounting base 10. When the key switch 40 needs to be repaired or replaced, only the lower cover plate 32 needs to be opened; the upper cover plate 31 encapsulates the magnetic ring 50 in the upper mounting area 101 of the mounting base 10. When the magnetic ring 50 needs to be repaired or replaced, only the upper cover plate 31 needs to be opened.
[0019] Combined with Figure 2 and attached Figure 3 As shown, the lower rod 21 of the knob 20 is inserted through the upper cover 31 and is slidably connected to the magnetic ring 50. The magnetic ring 50 is provided with a sensing chip 60 in the radial direction. The sensing chip 60 is a Hall chip. The bottom of the lower rod 21 of the knob 20 is in conflict with the key switch 40. The lower cover 32 is provided with an FPC circuit board 80, and the FPC circuit board 80 is electrically connected to the sensing chip 60. The side wall of the mounting seat 10 is provided with a groove 13 for accommodating the sensing chip 60, and the two sides of the groove 13 are provided with mounting claws 14 for clamping the FPC circuit board 80.
[0020] When the knob rotates the knob member 20 , the knob member 20 drives the magnetic ring 50 to rotate synchronously, and the sensing chip 60 senses the change of magnetic flux generated by the rotation of the magnetic ring 50 to generate a sensing signal.
[0021] Combined with Figure 2 and attached Figure 5 As shown, the mounting seat 10 is provided with a partition plate portion 11 between the upper mounting area 101 and the lower mounting area 102, and the partition plate portion 11 is provided with a middle through hole 12 for the lower rod portion 21 of the knob member 20 to pass through. A limit plate 70 is provided between the magnetic ring 50 and the upper cover plate 31 for limiting the downward movement height of the knob member 20. The knob member 20 is provided with a limit ring plate portion 22 above the lower rod portion 21 for limiting the initial height position of the knob member 20.
[0022] When the knob 20 is pressed downward, the lower rod 21 of the knob 20 presses the push switch 40, and the knob 20 moves downward until it is blocked by the limit plate 70, which is the lowest height of the knob 20. When the knob 20 is released, the push switch 40 drives the knob 20 to rebound upward, and the knob 20 moves upward until its limit ring plate 22 is blocked by the upper cover plate 31, which is the initial height of the knob 20.
[0023] The utility model has a small overall design size and can be applied to wearable devices with compact structural design such as VR glasses. The rotation function of the knob 20 can be used to adjust the volume of the VR glasses, which can meet the high-speed rotation in the flywheel mode. The knob 20 has a smooth touch when rotating, and the sound can be adjusted freely and smoothly, avoiding the garbled code that is easy to appear in mechanical encoders, and is more durable; the pressing function of the knob 20 can be used to switch the menu of the VR glasses. When pressed, it is silent without noise impact, and can be used to press the knob 20 to wake up the device, and the power consumption is very low, which is about 1.4μA after testing, which effectively improves the standby time of the wearable device.
