[0023] The embodiments of the present application will be further described in detail below with reference to the drawings and embodiments. The detailed description of the following embodiments and drawings are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0024] In order to better understand the present application, the present application will be further described below with reference to the drawings and embodiments:

[0025] Once the conventional ring is made, its diameter is fixed. However, the thickness of a person's finger can change due to temperature, time (such as slight relaxation after long-term wearing) or physiological changes (such as edema), when the ring is too tight, it can hinder blood circulation; when the ring is too loose, the ring is easy to fall off the finger and cause loss.

[0026] Based on this, the present application provides an intelligent ring with full-size adaptation, as shown in Figures 1-4 ​As shown, the smart ring includes a ring body 1, the ring body 1 includes a flexible shell 11, a deformation body 12 and a flexible control plate 13, the deformation body 12 and the flexible control plate 13 are arranged in the flexible shell 11, the ring body 1 is switched between a curled state and a flattened state by deformation, and the ring body 1 remains in the current state when there is no external force or the applied external force is less than the critical deformation force, that is, when the ring body 1 is in the curled state, it can always maintain the curled state under no external force or the applied external force is less than the critical deformation force, and when the ring body 1 is in the flattened state, it can always maintain the flattened state under no external force or the applied external force is less than the critical deformation force.

[0027] When the ring body 1 is in the curled state, the ring body 1 is surrounded to form a wearing cavity for adapting to the finger, and the inner diameter of the wearing cavity is adjusted by bending the ring body 1 to clamp and fix the finger. In this way, the smart ring adjusts the curvature to change the inner diameter of the wearing cavity by bending, which can dynamically adapt to the changes of the finger, ensure that the smart ring always closely fits the finger, avoid discomfort or ring falling caused by size mismatch, and greatly improve the comfort of wearing. When the ring is in the flattened state, its shape is flat, which is convenient for storage and charging.

[0028] It should be noted that the ring body 1 has a bistable structure, and the deformation principle of the ring body 1 is as follows:

[0029] The ring body 1 has residual stress, which can make the strain energy E inside the ring body 1 have two minimum values. Assuming that the axial curling radius of the ring body 1 is r, the curvature K in the axial direction is K = 1 / r. When the ring body 1 is switched from the flattened state to the curled state, the radius r changes from infinity to r2, and the curvature K changes from 0 to K2, as shown in Figure 5 As shown, the strain energy E inside the ring body 1 first increases and then rapidly decreases to a minimum value E2 as K increases. The straight and curl of the ring body 1 correspond to the two energy E minimum values A and C, both of which are stable states, so the ring body 1 has a bistable structure. The ring body 1 changes from straight to curved and needs to pass through an energy high point B, which is called an energy barrier. Under the action of external force, the ring body 1 overcomes the energy barrier B point, and because the BC segment is steep downward, the ring body 1 rapidly releases strain energy and rapidly deforms and curls. When the deformation is constrained, for example, when the finger size is large, the curvature cannot be greater than K m, at this time, the energy of the ring body 1 remains at point D, so that the smart ring can be stably clamped on the finger, reducing the risk of falling. Secondly, it can fit different sizes of fingers, thereby improving the comfort of wearing.

[0030] In this embodiment, the critical deformation force is the minimum external force required for the ring body 1 to undergo reversible plastic deformation, which can also be understood as the external force required for the ring body 1 to overcome the energy barrier.

[0031] In one embodiment, such as Figure 1 As shown, when the ring body 1 is in a curled state, the two ends of the ring body 1 overlap. By changing the curvature of the ring body 1, the inner diameter of the wearing cavity is adjusted, thereby changing the area of ​​the overlapping area at both ends of the ring body 1 to clamp and fix the finger. At this time, the ring body 1 has a ring structure without an opening.

[0032] In another embodiment, when the ring body 1 is in a curled state, there is a certain gap between the two ends of the ring body 1, that is, the two ends of the ring body 1 do not contact each other. The curvature can be adjusted by bending the ring body 1 to change the inner diameter of the wearing cavity. At this time, the ring body 1 has a ring structure with an opening.

[0033] In this embodiment, when the ring body 1 is in a flattened state, the cross-section of the deformable part 12 is arc-shaped. Specifically, the arc-shaped structure design can prevent the ring body 1 from curling up without external force when it is in a flattened state. Curling deformation is usually caused by residual stress inside the material or interference from the external environment (such as changes in temperature and humidity). Since the arc-shaped cross-section has a large bending stiffness, it can effectively resist the influence of these factors, thereby maintaining the flattened state of the ring body 1. This stability helps to prevent the ring body 1 from curling up uncontrollably.

[0034] In this embodiment, the ring body 1 also includes a power supply unit 14, which is electrically connected to the flexible control board 13. The power supply unit 14 includes a battery and a wireless charging sensor, both of which are electrically connected to the flexible control board 13. At least a portion of the wireless charging sensor is attached to the surface of the battery.

[0035] Specifically, the wireless charging induction pad is a key component for achieving contactless charging. It uses electromagnetic induction to convert the alternating magnetic field generated by an external wireless charging device into electrical energy, thus charging the battery. This design eliminates the need for users to plug and unplug charging cables; they simply place the smart ring on a compatible wireless charger to charge, greatly enhancing convenience.

[0036] In this embodiment, the wireless charging induction pad consists of a coil and a rectifier circuit. The coil is used to receive energy from an external magnetic field, and the rectifier circuit is used to convert the received alternating current into direct current to charge the battery. It should be noted that, in order to ensure charging efficiency, the wireless charging induction pad should be aligned with the transmitting coil of the external charger during charging.

[0037] In the embodiment, the part of the wireless charging induction sheet is attached to the surface of the battery, which can shorten the power transmission path, reduce energy loss, and improve charging efficiency. At the same time, such design can also save the internal space of the smart ring, so that the smart ring remains light and compact in structure.

[0038] It is worth mentioning that the flexible control board 13 provided in the embodiment is electrically connected with the battery and the wireless charging induction sheet through conductive materials (such as flexible wires, conductive ink, etc.), which have good flexibility and conductivity, and can maintain stable electrical connection when the smart ring is bent, ensuring that the signal transmission and power supply between components are not affected.

[0039] In the embodiment, the material of the flexible shell 11 includes but is not limited to silicone.

[0040] In the embodiment, the flexible control board 13 is provided with a sleep monitoring sensor, an optical blood oxygen sensor, and an optical heart rate sensor, and the ring body 1 is provided with grooves matched with the sleep monitoring sensor, the optical blood oxygen sensor, and the optical heart rate sensor. When the ring body 1 is in a curled state, the grooves face the wearing cavity formed around the ring body 1. More specifically, the flexible control board 13 is provided with a Bluetooth chip, which is used to connect with external devices. It should be noted that the embodiment does not involve the internal circuit design of the smart ring, so the related circuit structure will not be described again.

[0041] Specifically, the deformation body 12 is a memory metal spring, and the flexible control board 13 is a flexible printed circuit board.

[0042] In addition, the embodiment also provides a ring charging box, which includes a box body, and the box body is provided with a containing groove for placing the smart ring. Specifically, the smart ring provided in the embodiment is placed in the containing groove, at this time, the smart ring is in an unfolded state, which not only reduces the space occupancy of the charging box in the height direction, but also makes the smart ring easy to charge.

[0043] It should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product of the application is used, or the orientation or positional relationship commonly understood by those skilled in the art, or the orientation or positional relationship commonly used when the product of the application is used, which is only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element must have a specific orientation, structure and operation, and therefore cannot be understood as limiting the application.
