Referring to fig. 1 and 2, further, the ring body 100 further includes an outer shell 400 covering the outer side of the FPC assembly 300 and an inner shell 500 covering the inner side of the FPC assembly 300, and the adjusting mechanism 200 is disposed between two ends of the open loop of the FPC assembly 300.

Specifically, in one embodiment, the ring body 100 includes an open loop ring portion including the open loop FPC assembly 300, an outer housing 400, and an inner housing 500. The FPC assembly 300 (Flexible Printed Circuit, abbreviated as FPC assembly 300) is a flexible printed circuit board with high reliability, which is also called a flexible circuit board, or the like, and is made of polyimide or a polyester film as a base material. The FPC assembly 300 includes an assembly body provided in an open loop, and the adjustment mechanism 200 is provided between both ends of the open loop of the FPC assembly 300. That is, in one embodiment, the controller 310 and the like are all disposed on the assembly body. More specifically, the first magnet 210, the second magnet 220, and the controller 310 are fixed to the assembly body through an SMT process. Therefore, the controller 310 and other parts are integrated on the FPC assembly 300, so that the intelligent ring is beneficial to processing and forming, and the production efficiency of the intelligent ring is improved. The outer case 400 is coated on the outside of the FPC assembly 300, and the inner case 500 is coated on the inside of the FPC assembly 300, thereby providing protection and protection to the inner and outer sides of the FPC assembly 300.

Of course, the ring-opening ring portion may not adopt the structure of the FPC assembly 300. In an embodiment, the ring-opening ring portion may be further arranged in such a way that the controller 310 and other components are connected together by a wire harness.

Further, the inner shell 500 and the outer shell 400 are both closed-loop structures, and the inner shell 500 and the outer shell 400 are both made of soft rubber materials.

Specifically, in order to improve the aesthetic property of the smart ring, in an embodiment, the inner shell 500 and the outer shell 400 are both in a closed-loop structure, and in order to ensure the adjustability of the FPC assembly 300 between the inner shell 500 and the outer shell 400, the inner shell 500 and the outer shell 400 are both injection molded from soft rubber materials. Notably, in the general plastic industry, plastics with relatively low specific weights such as PP, PE and the like and relatively low surface hardness are called soft rubber; while PS, ABS, AS, rigid PVC, etc. plastics may be referred to as hard gums. The specific material of the soft rubber is not limited herein. Meanwhile, a non-adhesive agent is coated between the outer and

inner sleeves

240 and 250 and the outer and

inner shells

400 and 500. In the process of forming the intelligent ring, the inner case 500 and the outer case 400 are respectively coated on the inner and outer sides of the FPC assembly 300, and after the soft rubber layers of the inner case 500 and the outer case 400 are formed, the outer sleeve 240 and the inner sleeve 250 are in a peeled state from the outer case 400 and the inner case 500, so that the inner sleeve 250 can move relative to the outer sleeve 240. At this time, the soft rubber around the outer sleeve 240 and the inner sleeve 250 is thinner, i.e., the outer case 400 and the inner case 500 around the outer sleeve 240 and the inner sleeve 250 are thinner and have elasticity, and can be easily extruded, so that the size adjustment of the intelligent ring is more convenient.

In another embodiment, the inner shell 500 and the outer shell 400 are made of soft rubber only at the corresponding adjusting mechanism 200, and the rest of the inner shell 500 and the outer shell 400 may be made of hard material. Therefore, the size adjustment of the intelligent ring can be guaranteed. It should be noted that the hard material may be a hard rubber material or other materials such as metal. When the inner shell 500 and the outer shell 400 are made of soft rubber material at the position of the adjusting mechanism 200 and the rest is made of hard rubber material, the inner shell 500 and the outer shell 400 can be formed by a double injection molding integrated process.

Of course, the inner case 500 and the outer case 400 may also be of an open loop structure where the adjustment mechanism 200 is provided, and the adjustment mechanism 200 is connected between the first end 111 and the second end 112 of the FPC assembly 300, thereby adjusting the size of the smart ring. At this time, the inner case 500 and the outer case 400 may be made of soft rubber or hard rubber.

Referring to fig. 1 and 2, further, at least one pressure sensor assembly 320 is mounted on the FPC assembly 300, and the pressure sensor assembly 320 is electrically connected to the controller 310 and is used for collecting a pressure signal of a finger, so that the controller 310 can control the magnitude of a current flowing in the electromagnet according to the pressure signal.

Specifically, the FPC assembly 300 has at least one pressure sensor assembly 320 mounted thereon, i.e., at least one pressure sensor assembly 320 is mounted on the assembly body. The pressure sensor assembly 320 is electrically connected to the controller 310, and is configured to collect a pressure signal of the mobile phone, and after the pressure sensor assembly 320 transmits the pressure signal of the finger to the controller 310, the controller 310 controls the magnitude of the current flowing in the electromagnet according to the pressure signal. Thus, compared with the arrangement of the non-pressure sensor assembly 320, the intelligent finger ring can be more comfortable to wear by intelligently collecting the pressure signals of the fingers through the pressure sensor assembly.

In one embodiment, to ensure accuracy of the pressure signal of the finger, a plurality of pressure sensor assemblies 320 are disposed at intervals along the circumference of the FPC assembly 300, so as to provide a plurality of pressure signal acquisition points along the circumference of the finger. The controller 310 receives the pressure signal values transmitted from the plurality of pressure sensor assemblies 320 and then averages them, and then the controller 310 controls the magnitude of the current flowing in the electromagnet with the average pressure value. Further, the plurality of pressure sensor assemblies 320 are uniformly spaced along the circumference of the FPC assembly 300, which is advantageous for accuracy of finger pressure signal acquisition. Still further, an even number of pressure sensor assemblies 320 are disposed on the FPC assembly 300 at even intervals, so that the pressure sensor assemblies 320 can use the pressure signals of the finger relative positions, thereby further improving the accuracy of the finger pressure signals. In the scheme shown in the drawings of the present invention, four pressure sensor assemblies 320 are arranged along the circumferential direction of the FPC assembly 300, and thus, the present invention is advantageous for light weight, miniaturization and low cost of the intelligent ring on the premise of facilitating the acquisition accuracy of finger pressure signals, compared with the arrangement of more than four pressure sensor assemblies 320.

More specifically, the smart ring is in an initial state in which the size of the ring body 100 is at a maximum state, and thus can be easily put on the finger. After wearing the finger, press the switch key so that the battery supplies power for intelligent ring, the electro-magnet begins to produce the magnetism opposite with another magnetic structure spare, and magnetism can become big gradually along with the increase of electric current. At this time, the first magnet 210 and the second magnet 220 are gradually closed under the action of mutual attraction, and in this process, the elastic force of the elastic member 230 needs to be overcome to compress the elastic member 230, so that the diameter of the intelligent ring gradually becomes smaller. The plurality of pressure sensor assemblies 320 begin to collect pressure signals of the finger, and the main control chip averages the pressure values collected by the plurality of pressure sensor assemblies 320.
