In the third state of the pressingmember 20, the connectingshaft 23 is separated from themicroswitch 17 to cut off the signal of themicroswitch 17.

Referring to fig. 7 and 8, in an embodiment of the present invention, themagnetic member 30 is formed with a plurality of sectors connected in series along a circumferential direction of the pressingmember 20, and two adjacent sectors have opposite magnetic properties.

In the solution according to an embodiment of the present invention, themagnetic member 30 has a substantially cylindrical structure, i.e. themagnetic member 30 has an axial direction and a radial direction. Themagnetic member 30 is further provided with a through hole for inserting thecoupling shaft 23 therethrough so that themagnetic member 30 is fixed to a side wall surface of thecoupling shaft 23.

In one embodiment, the magnetizing direction of themagnetic component 30 may be along the axial direction of themagnetic component 30, or along the radial direction of themagnetic component 30. The magnetizing direction of themagnetic member 30 is preferably an axial direction, so that the end of themagnetic member 30 in the axial direction can be magnetically attracted to thehousing 10, and a plurality of sectors connected in sequence can be formed in the radial direction of themagnetic member 30. Further, it is also possible to obtain a structure in which the magnetic polarities of the adjacent two sectors are opposite in the radial direction so that the change in the magnetic flux can be accurately detected when themagnetic member 30 rotates, as with theinductive member 40. It is understood that the plurality of sectors have the same area so that the page turning operation can be performed when the pressingmember 20 is rotated at the same angle. Specifically, the number of sectors formed on themagnetic member 30 may be 4, 6, 8, 12, or the like, wherein the number of sectors formed on themagnetic member 30 is preferably 6.

Further, themagnetic member 30 may be a ferrite body that is integrally magnetized, and such a structure can make the structure of themagnetic member 30 firm. Themagnetic member 30 may be formed by a plurality of magnets. The plurality of permanent magnets can be fixedly connected in a viscose mode.

In an embodiment, the fixingmember 31 may also be a fixed cylinder, and a plurality of mounting grooves are arranged at intervals in a radial direction of the fixed cylinder, and each mounting groove is fixed to a magnet. Themagnetic member 30 may be structured in various ways, and the structure of themagnetic member 30 is not specifically described here.

Further, in an embodiment of the present invention, thesensing component 40 includes two hall sensors, and projections of the two hall sensors on themagnetic component 30 along the axial direction of thepressing component 20 are located in the same sector, or projections of the two hall sensors on themagnetic component 30 along the axial direction of thepressing component 20 are located in two sectors with the same magnetism respectively.

Referring to fig. 7 and 8, thesensing part 40 is provided with two hall sensors, which may be packaged together or may be provided independently. When the two hall sensors are packaged together, the projections of the positions of thesensing parts 40 on themagnetic part 30 are in the same sector; when the two hall sensors are independently arranged, the projection positions of the two hall sensors on themagnetic component 30 are respectively located in two sectors with the same magnetic pole. For example, as illustrated in fig. 8, with reference to one of the hall sensors (identified by a solid line), the position of the other hall element can be placed within any one of the dashed boxes (identified by A, B, C in fig. 8).

Referring to fig. 9 and 10, fig. 9 is a schematic diagram showing signal outputs of two hall sensors when the magnetic member rotates clockwise, and fig. 10 is a schematic diagram showing signal outputs of two hall sensors when the magnetic member rotates counterclockwise. The magnetic field of themagnetic component 30 during rotation is detected by two hall sensors at different positions, and different functions can be correspondingly set by different sequences of the hall sensors at different positions for sensing the magnetic field. For example, when the pressingmember 20 drives themagnetic member 30 to rotate in the clockwise direction, one of the hall sensors detects the magnetic field first, and the other of the hall sensors detects the magnetic field later, which may correspond to the functions of thesmart watch 1000, such as forward page turning, forward scrolling, and screen display enlarging; on the contrary, when the pressingmember 20 drives themagnetic member 30 to rotate in the counterclockwise direction, thesmart watch 1000 may have functions of turning pages in a reverse direction, scrolling in a reverse direction, and reducing a display screen. The sequence of the induction magnetic fields of the hall sensors at different positions is different, and different functions can be correspondingly arranged, which are not listed one by one.
