It may be necessary to control the wearable device through a mobile phone or computer, which is cumbersome.
[0004] Therefore, there is an urgent need for a small and specialized control device to solve the mode switching problem of wearable devices. Utility Model Content

By rotating the knob, the connection and disconnection states between the continuous conductive ring and the plurality of conductive sheets are changed, thereby realizing mode switching, and the indicator mark indicates the corresponding mode identification.
[0024] Specifically, Figure 1-5 As shown, the multi-mode switch includes a base 1 and a knob 2 , and the knob 2 can rotate axially on the base 1 .
[0025] The base 1 includes a base plate 11 and a back plate 14 , and the base plate 11 is fixed on the upper surface of the back plate 14 .
[0026] A continuous conductive ring 12 and a discontinuous conductive ring 13 are provided on the upper surface of the substrate 11. The continuous conductive ring 12 and the discontinuous conductive ring 13 have the same center. In this embodiment, the substrate 11 is preferably a circuit board so as to form an electrical connection line with the continuous conductive ring 12. In addition, the radius of the continuous conductive ring 12 is greater than the radius of the discontinuous conductive ring 13. Figure 3 Of course, for the technical solution of the present utility model, it is also possible that the radius of the continuous conductive ring 12 is smaller than the radius of the discontinuous conductive ring 13 .
[0027] The continuous conductive ring 12 is a conductive component that can be connected to an electrical connection line.
[0028] The intermittent conductive ring 13 includes a plurality of conductive sheets 131 and a sliding sheet 132 disposed between two of the conductive sheets 131. The plurality of conductive sheets 131 are disposed at intervals on the circumference of the intermittent conductive ring 13. Figure 3 As shown, in this embodiment, four conductive sheets 131 are evenly arranged at the positions of 0°, 90°, 180° and 270° of the circumference, and each conductive sheet 131 occupies an arc length of about 15°. The conductive sheets 131 can be connected to the electrical connection circuits respectively. The slide 132 is a preferred arrangement. In the technical solution of the utility model, the purpose of arranging the slide 132 is to make the second terminal abut against the slide 132 during the rotation of the knob 2, rather than directly abutting against the substrate 11, so as to reduce the wear on the substrate 11 and increase the service life of the product. The slide 132 can be made of conductive or insulating material. When the slide 132 is made of conductive material, the slide 132 must be spaced apart from the conductive sheet 131; when the slide 132 is made of insulating material, the above spacing is optional.
[0029] Corresponding to the positions of the multiple conductive sheets 131, multiple mode identifications 15 for switching are provided on the upper surface of the back plate 14, so that during the use of the multi-mode switching switch of this embodiment, the operator can clearly know that rotating the knob 2 to the corresponding position can switch to the corresponding mode.
[0030] The knob 2 includes an indication mark 24 and a first terminal 21 and a second terminal 22 for respectively correspondingly abutting against the continuous conductive ring 12 and the intermittent conductive ring 13. The indication mark 24 is arranged on the outer circumference of the knob 2, and can change the indication direction as the knob 2 rotates. The first terminal 21 and the second terminal 22 are electrically connected to each other, and the knob 2 rotates with the center of the continuous conductive ring 12 and the intermittent conductive ring 13 as the rotation axis, and the rotation tracks of the first terminal 21 and the second terminal 22 coincide with the continuous conductive ring 12 and the intermittent conductive ring 13, respectively. By rotating the knob 2, the connection and disconnection states between the continuous conductive ring 12 and the plurality of conductive sheets 131 are changed, thereby realizing mode switching, and the indication mark 24 indicates the corresponding mode identification 15.
[0031] In this embodiment, a rotating shaft 23 is erected on the lower surface of the knob 2, and the rotating shaft 23 is rotatably inserted into the shaft hole 16 of the base 1, so as to realize the relative rotation of the knob 2 and the base 1. Those skilled in the art can understand that the above-mentioned rotation method of the rotating shaft and the shaft hole is only an example, and the relative rotation of the knob 2 and the base 1 can also be realized by, for example, providing a protrusion on the outer edge of the knob 2 and providing a circular groove on the base 1 corresponding to the protrusion.
[0032] Among them, the first terminal 21 and the second terminal 22 are arranged on the lower surface of the knob 2, and the first terminal 21, the second terminal 22 and the electrical connection line 26 therebetween are formed by a conductor bent into a gate shape, and the electrical connection line between the first terminal 21 and the second terminal 22 is fixed to the lower surface of the knob 2, so that the first terminal 21 and the second terminal 22 extend from the lower surface of the knob 2 toward the upper surface of the substrate 11 and can abut against the upper surfaces of the continuous conductive ring 12 and the intermittent conductive ring 13 (conductive sheet 131 and sliding sheet 132).
[0033] When the multi-mode switching switch of this embodiment is in use, the continuous conductive ring 12 is connected to the signal input end, and the multiple conductive sheets 131 on the intermittent conductive ring 13 are connected to the signal detection end of the processor. The processor detects the connection status between the continuous conductive ring 12 and the conductive sheets 131 at the signal detection end, so that the processor can switch the mode of the controlled device.
[0034] For example, in the embodiment shown in the figure, a high level is applied to the continuous conductive ring 12 through the signal input terminal.
[0035] In one switching mode, the four conductive sheets 131 are respectively connected to the four I / O ports of the processor. By rotating the knob 2, the four conductive sheets 131 will be electrically connected to the continuous conductive ring 12 respectively, and the I / O ports corresponding to the four conductive sheets 131 will respectively detect a high level. When a high level is detected at different I / O ports, the corresponding mode will be started to control the controlled device.
[0036] In another switching mode, four conductive sheets 131 are connected to the same I / O port of the processor, and the knob 2 is rotated so that the four conductive sheets 131 are electrically connected to the continuous conductive ring 12 respectively. Each conductive sheet 131 will generate a pulse when electrically connected to the continuous conductive ring 12, and the processor calls the corresponding mode to control the controlled device by counting the pulses (high level). In this embodiment, four conductive sheets 131 are provided, so the multi-mode switching switch can switch between four modes. During operation, the 1st, 5th, 9th, 13th... high levels correspond to the first mode, the 2nd, 6th, 10th, 14th... high levels correspond to the second mode, the 3rd, 7th, 11th, 15th... high levels correspond to the third mode, and the 4th, 8th, 12th, 16th... high levels correspond to the fourth mode. In the above switching mode, the multi-mode switching switch preferably includes a unidirectional rotating component to prevent mode confusion caused by the reverse rotation of the knob 2. Figure 5 As shown, the one-way rotating member includes a circle of ratchet teeth 25 ( Figure 5 Only one ratchet 25 is shown in the figure, and a groove component 17 is arranged on the base 1 and can be engaged with the ratchet 25. The outer wall on one side of the groove component 17 has an inclined slope for the ratchet 25 to slide, and the outer wall on the other side of the groove component 17 is a vertical surface that blocks the ratchet 25.
[0037] Based on the description of the above two working modes, those skilled in the art can also understand that a mixed mode can be adopted, that is, at least two of the four conductive sheets 131 are connected to the same I / O port of the processor, and the remaining conductive sheets 131 are respectively connected to separate I / O ports corresponding to one mode. For example, two conductive sheets 131 are connected to the first I / O port of the processor, and the other two conductive sheets 131 are respectively connected to the second I / O port and the third I / O port of the processor; or, three conductive sheets 131 are connected to the first I / O port of the processor, and another conductive sheet 131 is connected to the second I / O port of the processor.
[0038] In addition, in a preferred embodiment, the intermittent conductive ring 13 protrudes from the substrate 11, and the distance between the slide 132 and the adjacent conductive sheet 131 is slightly greater than the circumferential width of the end of the second terminal 22 abutting against the intermittent conductive ring 13, so that during the rotation of the knob 2, the second terminal 22 reaches the second conductive sheet 131 from the first conductive sheet 131 through a slide 132. When passing through the first gap between the first conductive sheet 131 and the slide 132, the operator can feel that the first terminal 22 is trapped in the first gap, thereby realizing that the mode determined by the first conductive sheet 131 is about to end or has ended and turned to the slide 132 without mode selection; when passing through the second gap between the slide 132 and the second conductive sheet 131, the operator can feel that the first terminal 22 is trapped in the second gap, thereby realizing that the mode determined by the second conductive sheet 131 is about to enter. Therefore, by setting a gap between the slide 132 and the adjacent conductive sheet 131, the operator can be provided with a rotation feel, and the operator can know the mode switching even if he does not look at the multi-mode switch.
