[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1

[0028] This utility model discloses a sliding double-layer finger ring. (Refer to...) Figure 1 The device includes: an inner ring 1, including a first permanent magnet 11, the inner ring 1 being circular; an outer ring 2, including a second permanent magnet 27, the outer ring 2 being disposed outside the inner ring 1, the diameter of the outer ring 2 being larger than the diameter of the inner ring 1; a sliding ball 3, disposed between the inner ring 1 and the outer ring 2, the outer ring 2 being rotatable relative to the inner ring 1; and a magnetic flux assembly 21, connected to the second permanent magnet 27, used to generate and store electrical energy during the mutual rotation of the first permanent magnet 11 and the second permanent magnet 27.

[0029] Based on the above structure, the inner ring 1 is worn on the finger, and the outer ring 2 rotates relative to the inner ring under the action of the sliding ball 3. Since both the inner ring 1 and the outer ring 2 are permanent magnets, during rotation, the inner ring 1 cuts the magnetic flux lines of the outer ring 2, thereby generating electromagnetic induction. The magnetic flux-current assembly 21 is connected to the second permanent magnet 27. While the first permanent magnet 11 and the second permanent magnet 27 generate electromagnetic induction, an induced current is generated in the magnetic flux-current assembly 21 and stored to form the electrical energy usable by the double-layer ring.

[0030] Optionally, based on the function of the sliding ball 3, the first permanent magnet 11 and the second permanent magnet 27 can rotate relative to each other, thereby forming an electromagnetic induction phenomenon, effectively generating and storing electrical energy, and improving the battery life of the double-layer ring.

[0031] In a preferred embodiment, the device further includes: a first recessed ring 12, disposed on the surface of the inner ring 1 and on the side near the outer ring 2; the recessed shape of the first recessed ring 12 is semi-circular, and the diameter of the semi-circular recess of the first recessed ring 12 matches the diameter of the sliding ball 3; the sliding ball 3 is embedded in the first recessed ring 12; and a second recessed ring 22, disposed on the surface of the outer ring 2 and on the side near the inner ring 1; the recessed shape of the second recessed ring 22 is semi-circular, and the diameter of the semi-circular recess of the second recessed ring 22 matches the diameter of the sliding ball 3; the sliding ball 3 is embedded between the first recessed ring 12 and the second recessed ring 22.

[0032] Reference Figure 2 and Figure 3 Based on the above structure, a first recessed ring 12 is provided on the inner ring 1, and a second recessed ring 22 is provided on the outer ring 2, so that the sliding ball 3 is embedded between the first recessed ring 12 and the second recessed ring 22. Simultaneously, it is necessary to ensure that the diameters of the first recessed ring 12 and the second recessed ring 22 are the same as the diameter of the sliding ball 3, or that the diameters of the first recessed ring 12 and the second recessed ring 22 are slightly larger than the diameter of the sliding ball 3, so that the sliding ball 3 is held between the first recessed ring 12 and the second recessed ring 22 and will not disengage.

[0033] It should be noted that the first recessed ring 12 is embedded in the inner ring 1, and its length is the same as that of the inner ring 1. It is located at the middle position of the width of the inner ring 1, and the degree of recess is less than the thickness of the inner ring 1. Similarly, the second recessed ring 22 is embedded in the outer ring 2, located at the middle position of the width of the outer ring 2, and the degree of recess must be less than the thickness of the outer ring 2.

[0034] In this preferred embodiment, multiple sliding balls 3 are provided, and the multiple sliding balls 3 are evenly placed between the first recessed ring 12 and the second recessed ring 22.

[0035] Based on the above structure, to ensure the balance of the sliding ball 3 and to support the gap between the inner ring 1 and the outer ring 2, multiple sliding balls 3 are arranged evenly. Specifically, four sliding balls 3 are placed in pairs at four positions. This effectively enables the sliding balls 3 to support the gap between the inner ring 1 and the outer ring 2.

[0036] In this preferred embodiment, the magnetic flux assembly 21 includes: a wound wire layer 23, which is circular in shape and laid on the surface of the second permanent magnet 27, and disposed on the side of the second permanent magnet 27 away from the first permanent magnet 11. The wound wire layer 23 generates electrical energy based on the mutual rotation of the first permanent magnet 11 and the second permanent magnet 27; and a battery mainboard layer 24, which is circular in shape and laid on the surface of the wound wire layer 23, and disposed on the side of the wound wire layer 23 away from the first permanent magnet 11, connected to the wound wire layer 23, and used to store electrical energy.

[0037] Reference Figure 1 Based on the above structure, the wound wire layer 23 is formed by multiple lines and laid on the surface of the second permanent magnet 27. During the rotation of the second permanent magnet 27 relative to the first permanent magnet 11, the magnetic field lines are cut, forming electromagnetic induction. Based on the principle of magnetism generating electricity, current is formed on the wound wire layer 23 connected to the second permanent magnet 27, thereby realizing the phenomenon of magnetism generating electricity.

[0038] Optionally, the wired layer 23 is connected to the battery motherboard layer 24. The current generated in the wired layer 23 forms electrical energy stored in the battery motherboard layer 24 for use by the dual-layer ring, effectively realizing the storage of electrical energy and extending the standby time of the dual-layer ring.

[0039] In this preferred embodiment, it further includes: a flexible display layer 25, which is semi-circular in shape, laid on the surface of the battery motherboard layer 24, and disposed on the side of the battery motherboard layer 24 away from the wound wire layer 23, and electrically connected to the battery motherboard layer 24, for displaying the ring content.

[0040] Based on the above structure, the double-layer ring features a flexible display layer 25, which can display the current battery level and the desired functions. The flexible display layer 25 covers the surface of the battery motherboard layer 24, but only covers half of the ring. That is, the circumference of the flexible display layer 25 is half the circumference of the outer ring 2, and the flexible display layer 25 is only present on the part facing the back of the hand when worn.

[0041] Optionally, the flexible display layer 25 is connected to the battery motherboard layer 24, and the battery motherboard layer 24 supplies power to the flexible display layer 25. The current is generated based on the magnetoelectric effect of the first permanent magnet 11 and the second permanent magnet 27. After being processed by the rectification and voltage regulation circuit, the current is stored in the battery motherboard layer 24, so that the battery motherboard layer 24 stores electricity and can continuously supply power to the flexible display layer 25, thereby extending the service life of the flexible display layer 25.

[0042] In this preferred embodiment, the width of the flexible display layer 25 is set between 2cm and 4cm.

[0043] Based on the above structure, the circumference of the flexible display layer 25 is half the circumference of the outer ring 2, and its width is set between 2cm and 4cm. When displaying text content, a width of 2-4cm can display two lines of text. If the width is too small, the displayed text will be too small, making it inconvenient for users to view the content. If the width is too large, the displayed content will be larger, but it will be too wide when worn on the finger, possibly covering the first finger joint and restricting finger bending. Therefore, setting the width of the flexible display layer 25 between 2cm and 4cm can effectively balance the relationship between content display and finger wearing, thus improving the user experience.

[0044] In a preferred embodiment, the device further includes: a display protection frame 26, which is disposed on the surface of the flexible display layer 25 and is in the shape of a ring; the display protection frame 26 includes a first protection ring and a second protection ring, the width of the first protection ring is the same as the width of the second protection ring and is smaller than the width of the flexible display layer 25; the first protection ring and the second protection ring are both disposed on the side of the flexible display layer 25 away from the inner ring 1, and are respectively disposed at two edges of the flexible display layer 25.

[0045] Reference Figure 4 Based on the above structure, the corners of the flexible display layer 25 are easily bumped, which can damage the flexible display layer 25. Therefore, a display protection frame 26 is provided, which is set on both sides of the width of the flexible display layer 25 and protrudes a certain height relative to the flexible display layer 25. That is, a first protective ring is set on one side of the flexible display layer 25 and a second protective ring is set on the opposite side. The first and second protective rings are set at the edge of the flexible display layer 25. The protrusion height prevents the corners of the flexible display layer 25 from being bumped during use.

[0046] Optionally, a display protective frame 26 can be provided, which can not only protect the flexible display screen, but also give the surface of the double-layer ring a concave-convex shape, thereby improving the aesthetics of the double-layer ring.

[0047] In a preferred embodiment, it further includes an insulating protective layer 13, which is laid on the surface of the first permanent magnet 11 and disposed on the side away from the outer ring 2.

[0048] Based on the above structure, the first permanent magnet 11 and the second permanent magnet 27 rotate relative to each other, generating magnetic induction. The magnetic field lines within the second permanent magnet 27 are cut, causing current to be generated in the connected lines. However, there is a possibility that the first permanent magnet 11 may generate a small current, and to prevent the first permanent magnet 11 from becoming conductive and affecting the user experience, an insulating protective layer 13 is provided on the inner surface of the first permanent magnet 11 to effectively prevent current from flowing to the user's fingertips, thus avoiding a decrease in user experience.

[0049] It should be noted that the induced current is small and will not harm the human body. There may be a slight tingling sensation, but it will not cause electric shock. Therefore, setting an insulating protective layer 13 on the inner surface of the inner ring 1 can reduce the possibility of current flowing to the fingertip and improve the user experience.

[0050] In this preferred embodiment, the thickness of the first permanent magnet 11 is the same as the thickness of the second permanent magnet 27.

[0051] Based on the above structure, the first permanent magnet 11 and the second permanent magnet 27 have the same thickness. When setting the first recessed ring 12 and the second recessed ring 22, the recess depth can be set to be the same, effectively embedding the sliding ball 3 between the first recessed ring 12 and the second recessed ring 22. The recess depth is the same, that is, the sliding ball 3 is set in the middle position of the first recessed ring 12 and the second recessed ring 22. The symmetrical arrangement makes the appearance of the double-layer ring more beautiful.

[0052] The implementation principle of a sliding double-layer ring according to this utility model embodiment is as follows:

[0053] The double-ring design includes an outer ring 2 and an inner ring 1. The outer ring 2 and the inner ring 1 are connected by a sliding ball bearing 3, allowing the outer ring 2 to rotate freely relative to the inner ring 1. Permanent magnets (a first permanent magnet 11 and a second permanent magnet 27) are respectively disposed on the inner side of the outer ring 2 and the outer side of the inner ring 1. When the outer ring 2 rotates relative to the inner ring 1, the relative motion between the first permanent magnet 11 and the second permanent magnet 27 generates a changing magnetic field, thereby inducing a current in the coil (with a winding layer 23) wound on the outer ring 2. This current is rectified and regulated by a voltage regulator circuit and then stored in the battery mainboard layer 24.

[0054] It generates electricity using the wearer's natural hand movements, requiring no additional external energy input and achieving energy self-sufficiency. This effectively extends the standby time of the double-layer ring, improving product usability and user experience.

[0055] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
