DETAILED DESCRIPTION OF THE EMBODIMENTS

In order that those skilled in the art can better understand the technical solutions of the present invention, a further detailed description of the present invention will be given below in combination with the accompanying drawings and specific implementations.

FIG. 1 is a schematic diagram of a structure of an electronic equipment with a handheld device according to an embodiment of the present invention, FIG. 9 is a schematic diagram of contact points on a first disc body of the handheld device according to an embodiment of the present invention, and FIG. 10 is a schematic diagram of probes on a second disc body of the handheld device according to an embodiment of the present invention.

With reference to FIGS. 1, 9 and 10, the electronic equipment according to an exemplary embodiment includes a control unit 50 and a handheld device electrically connected with the control unit 50. The handheld device includes an annulus 10 arranged at outside of a shell 60 of the electronic equipment, and a first disc body 20 and a second disc body 30 arranged inside the shell 60. A first contact point and a plurality of second contact points electrically connected with the first contact point are arranged on the first disc body 20, and directions and lengths of connecting lines between respective second contact points and the first contact point are different. A first probe and a plurality of second probes electrically connected with the control unit 50 are arranged on the second disc body 30, the first probe is electrically connected with the first contact point on the first disc body 20, and when the first disc body 20 rotates, the second probes are respectively in contact with the second contact points on the first disc body 20 in sequence. The annulus 10 is connected to the first disc body 20 and is used for driving the first disc body 20 to rotate, and the second disc body 20 is fixed to the shell 60 of the electronic equipment.

With reference to FIGS. 9 and 10, four contact points are arranged on the first disc body 20, wherein the first contact point is arranged at a center of the first disc body 20, and the first disc body 20 can rotate around the first contact point. The rest three second contact points are respectively arranged on the circumferences of concentric circles with the first contact point as the center and having different radiuses. The second contact points are electrically connected with the first contact point through conducting wires (for example, copper wires). The conducting wires used for connecting the first contact point and the second contact points may be exposed in the air. Alternatively, an insulating layer may cover on the conducting wires with only the first contact point and the second contact points exposed.

Four probes, namely one first probe and three second probes, are arranged on the second disc body 30. The first probe is arranged at a center of the second disc body 30 and is always kept in contact with the first contact point on the first disc body 20. When the first disc body 20 rotates around the first contact point, the three second probes are respectively in contact with the three second contact points on the first disc body 20 in sequence. In addition, the first probe and the second probes are electrically connected with the control unit 50 of the electronic equipment, and the control unit 50 may provide different voltages for the second probes and a grounding voltage for the first probe.

With reference to FIG. 1, for example, the control unit 50 may include four pins 1 to 4 for providing the voltages to the four probes. The voltage provided by the pin 4 for the first probe is 0V, the voltage provided by the pin 1 for the first second probe (referred to as second probe 1 below) is 1.2V, the voltage provided by the pin 2 for the second second probe (referred to as second probe 2 below) is 0.8V, and the voltage provided by the pin 3 for the third second probe (referred to as second probe 3 below) is 0.4V.

When the first disc body 20 rotates to a first preset angle, the second probe 1 is in contact with the first second point (referred to as second contact point 1′ below) on the first disc body 20. At this time, the second probe 1, the second contact point 1′, the first probe and the control unit 50 form a loop, the pin 4 of the control unit 50 may detect a voltage of 1.2V, so that the control unit 50 may determine that the second probe 1 is in contact with the second contact point P. When the first disc body 20 rotates to a second preset angle, the second probe 1 is separated from the second contact point 1′, and the second probe 2 is in contact with the second contact point (referred to as second contact point 2′ below) on the first disc body 20. At this time, the second probe 2, the second contact point 2′, the first probe and the control unit 50 form a loop, the pin 4 of the control unit 50 may detect a voltage of 0.8V, so that the control unit 50 may determine that the second probe 2 is in contact with the second contact point 2′. When the first disc body 20 rotates to a third preset angle, the second probe 2 is separated from the second contact point 2′, and the second probe 3 is in contact with the third second contact point (referred to as second contact point 3′ below) on the first disc body 20. At this time, the second probe 3, the second contact point 3′, the first probe and the control unit 50 form a loop, the pin 4 of the control unit 50 may detect a voltage of 0.4V, so that the control unit 50 may determine that the second probe 3 is in contact with the second contact point 3′.

Since the second disc body 50 is fixed to the shell 60, positions of the second probe 1, the second probe 2 and the second probe 3 are kept unchanged. When the first disc body 20 rotates clockwise (as shown in FIG. 9), the second contact point 1′, the second contact point 2′ and the second contact point 3′ on the first disc body 20 are in contact with the second probe 1, the second probe 2 and the second probe 3 on the second disc body 30 in sequence, so that the pin 4 of the control unit 50 sequentially detects the voltages of 1.2V, 0.8V and 0.4V. When the first disc body 20 rotates counterclockwise, the sequence of the detected voltages is reverse. Therefore, the control unit 50 may determine a rotation direction of the first disc body 20 according to the change of the detected voltages. When the control unit 50 is connected with a volume adjustment circuit or a brightness adjustment circuit, the volume or brightness may be increased or decreased according to the rotation direction of the first disc body 20, so as to control the electronic equipment.

The control unit 50 can change the volume or brightness for an adjustment unit according to a group of detected complete signals (for example, 1.2V, 0.8V and 0.4V, or 0.8V, 0.4V and 1.2V, or 0.4V, 1.2V and 0.8V in the case of clockwise rotation; or 0.4V, 0.8V and 1.2V, or 0.8V, 1.2V and 0.4V, or 1.2V, 0.4V and 0.8V in the case of counterclockwise rotation).

According to an exemplary embodiment, the number of the second probes and the number of the second contact points may be three for convenient operation.

With reference to FIGS. 1 to 4, according to the current embodiment, the annulus 10 is implemented as a ring 10 used for holding a finger of a user. A connecting support 21 protruding outwards from the shell 60 of the electronic equipment may be arranged on the first disc body 20, a groove is formed in one end of the connecting support 21, and first through holes 212 are formed in two side walls 211 of the groove. A first projection 11 matched with the groove may be arranged on the ring 10, and a second through hole 111 is formed in the first projection 11. The handheld device may further include a first connecting shaft 40 penetrating through the first through holes 212 in the two side walls 211 of the groove and the second through hole 111 in the first projection 11 for connecting the ring 10 to the connecting support 21 of the first disc body 20, and the ring 10 is capable of being in contact with the shell 60 of the electronic equipment by rotating around the first connecting shaft 40.

Since the ring 10 may be in contact with the shell 60 by rotating around the first connecting shaft 40, the handheld device according to the present embodiment has a simple structure and does not occupy excessive space.

With reference to FIGS. 2 and 3, end parts of the two side walls 211 of the groove of the connecting support 21 may be formed to be arc-shaped, and end part of the first projection 11 may be formed to be arc-shaped also. When the ring 10 is in contact with the shell 60 by rotating around the first connecting shaft 40 (namely, the ring 10 is folded onto the shell 60 of the electronic equipment), the end parts of the two side walls 211 of the groove and the end part of the first projection 11 will be exposed at outside. When these end parts are arc-shaped, better safety can be provided.
