[0040] A smart ring is a wearable device that integrates multiple functions such as health management, sports monitoring, and communication.

[0041] Currently, most smart rings have fixed sizes, but the fingers of different users are of different thicknesses, and the thicknesses of different fingers of the same user are different, which makes the same smart ring suitable for fewer people and has a narrow scope of application.

[0042] The present invention provides a smart ring.

[0043] See also Figures 1 to 3 In one embodiment of the present invention, the smart ring includes a ring body 100, an adjustment component 200 and a controller 600. The ring body 100 is provided with an adjustment hole 111; the adjustment component 200 is installed on the ring body 100, and the adjustment component 200 includes an elastic contact member 300 and an air charging and discharging device 400. The elastic contact member 300 is provided with a pressure sensor 310 (such as Figure 4 As shown), the inflation and deflation device 400 is used to inflate and deflate the elastic contact member 300 so that the elastic contact member 300 extends out of or retracts into the adjustment hole 111.

[0044] It can be understood that the ring body 100 has a ring opening for the finger to wear, and the finger is inserted into the ring opening of the ring body 100, so that the smart ring is worn on the finger. The ring body 100 has a receiving space, and the adjustment component 200 is accommodated in the receiving space. The ring body 100 is provided with an adjustment hole 111, which connects the ring opening and the receiving space.

[0045] The elastic contact piece 300 is installed corresponding to the adjustment hole 111, and the elastic contact piece 300 is used to contact with the finger. It can be understood that the elastic contact piece 300 is made of elastic material, which has the ability to deform. When the inflation and deflation device 400 inflates the elastic contact piece 300, the elastic contact piece 300 can expand accordingly and extend out of the adjustment hole 111; when the inflation and deflation device 400 deflates the elastic contact piece 300, the elastic contact piece 300 can shrink accordingly and retract into the adjustment hole 111. In this way, as the inflation and deflation device 400 is inflated and deflated, the height of the elastic contact piece 300 extending out of the adjustment hole 111 can be adjusted. At the same time, the elastic contact piece 300 made of elastic material contacts the human body, which can improve the wearing comfort of the smart ring.

[0046] For the convenience of explanation, the side close to the center of the smart ring is defined as the inner side, and the side away from the center of the smart ring is defined as the outer side. In one embodiment, in the initial state of the smart ring, the inner upper surface of the elastic contact piece 300 is flush with the inner surface of the ring body 100, and the ring opening has the largest space at this time. On the one hand, compared with the upper surface of the elastic contact piece 300 protruding from the inner surface of the ring body 100, the adjustment range of the ring opening of the smart ring is maximized, making the smart ring have the widest range of application. On the other hand, compared with the upper surface of the elastic contact piece 300 located in the adjustment hole 111, this is beneficial to the aesthetics of the smart ring and also prevents dust and the like from falling between the elastic contact piece 300 and the adjustment hole 111.

[0047] The controller 600 is installed on the ring body 100 and is electrically connected to the pressure sensor 310 and the inflation and deflation device 400; the controller 600 controls the stopping of inflation of the inflation and deflation device 400 according to the pressure value detected by the pressure sensor 310, thereby controlling the height of the elastic contact piece 300 extending out of the adjustment hole 111.

[0048] Specifically, the controller 600 is also housed in the accommodating space, and a pressure sensor 310 is installed on the elastic contact piece 300. When the smart ring is worn, the finger contacts the elastic contact piece 300, and the pressure sensor 310 can detect the pressure value of the finger and transmit the pressure value to the controller 600. The controller 600 determines the degree of contact between the elastic contact piece 300 and the finger according to the pressure value, and controls the inflation of the inflation and deflation device 400 to stop.

[0049] When the smart ring needs to be worn, if the pressure value detected by the controller 600 is less than the first preset pressure value, the controller 600 controls the inflation and deflation device 400 to continue to inflate. As the inflation and deflation device 400 inflates, the height of the elastic contact member 300 extending out of the adjustment hole 111 increases, and the space of the ring of the smart ring decreases. When the detected pressure value is equal to the first preset pressure value, the height of the elastic contact member 300 extending out of the adjustment hole 111 is just right, and the controller 600 controls the inflation and deflation device 400 to stop inflating. At this time, the tightness of the contact between the smart ring and the finger is just right.

[0050] When the smart ring needs to be removed from the finger, the controller 600 controls the inflation and deflation device 400 to deflate, and when the finger is not in contact with the smart ring, the smart ring can be removed from the finger.

[0051] It is worth noting that the first preset pressure value can be set according to different usage habits, and the first preset pressure value is not limited here. In other embodiments, the first preset pressure value can also be set to a certain pressure range.

[0052] In one embodiment, the inflation and deflation of the elastic contact member 300 can also be used to store a small ring. The outer diameter of the small ring is smaller than the inner diameter of the smart ring of the present invention, so the small ring can be placed in the ring of the smart ring, and the elastic contact member 300 is inflated to make the elastic contact member 300 contact the outer ring of the small ring, so that the small ring is clamped on the smart ring, which facilitates the storage of the smart ring and the small ring and saves storage space.

[0053] The technical solution of the embodiment of the present invention is to set a ring body 100, and an adjustment component 200 and a controller 600 installed on the ring body 100 in the smart ring, wherein the ring body 100 is provided with an adjustment hole 111, and the adjustment component 200 includes an elastic contact 300 arranged corresponding to the adjustment hole 111, and an inflation and deflation device 400 capable of inflating and deflation of the elastic contact 300, and a pressure sensor 310 is also arranged on the elastic contact 300, and the controller 600 is electrically connected to the pressure sensor 310 and the inflation device. The controller 600 controls the inflation of the inflation and deflation device 400 to stop according to the pressure value detected by the pressure sensor 310, thereby controlling the height of the elastic contact 300 extending out of the adjustment hole 111, thereby adjusting the wearing tightness of the smart ring, thereby improving the application range of the smart ring and improving the wearing comfort of the smart ring.

[0054] In an embodiment of the present invention, the controller 600 also controls the stopping of deflation of the inflation and deflation device 400 according to the pressure value detected by the pressure sensor 310 .

[0055] Specifically, in one embodiment, the stopping of deflation of the inflation and deflation device 400 is determined according to the pressure value. When the smart ring needs to be removed from the finger, if the pressure value detected by the controller 600 is greater than the second preset pressure value, the controller 600 controls the inflation and deflation device 400 to continue deflation; when the detected pressure value is equal to or less than the second preset pressure value, the controller 600 controls the inflation and deflation device 400 to stop deflation, and the smart ring can be easily removed.

[0056] It is worth noting that the second preset pressure value can be set according to different usage habits, and no limitation is imposed on the second preset pressure value. In other embodiments, the second preset pressure value can also be set to a certain pressure range.

[0057] Of course, in one embodiment, the stopping of deflation of the inflation and deflation device 400 can also be determined by the retraction degree of the elastic contact member 300. Specifically, when the inflation and deflation device 400 deflates to the point where the inner upper surface of the elastic contact member 300 is flush with the inner surface of the ring body 100, the controller 600 controls the inflation and deflation device 400 to stop deflation. In one embodiment, a height sensor electrically connected to the controller 600 can be provided on the elastic contact member 300, and the height value of the elastic contact member 300 detected by the height sensor can be used to determine whether the elastic contact member 300 has retracted into place.

[0058] In another embodiment, the inflation and deflation device 400 can also be controlled to stop deflation after the elastic contact member 300 discharges all the inflation. In one embodiment, an air flow sensor electrically connected to the controller is provided on the elastic contact member 300, and whether the inflation value and deflation value of the elastic contact member 300 detected by the air flow sensor are the same is used to determine whether the elastic contact member 300 can stop deflation. Of course, the inflation and deflation device 400 can also be controlled to stop deflation after the elastic contact member 300 discharges a certain amount of all the inflation. Here, there is no restriction on the exhaust volume of the elastic contact member 300.

[0059] The following description will be made by taking the example of the controller 600 controlling the stopping of the deflation of the inflation and deflation device 400 according to the pressure value detected by the pressure sensor 310 .

[0060] See also Figures 3 to 5 In an embodiment of the present invention, the elastic contact member 300 has an air chamber 320, a first air guide hole 330 communicating with the air chamber 320 is provided on the elastic contact member 300, and a ventilation hole 112 communicating with the outside is provided on the ring body 100; the inflation and deflation device 400 includes a motor 410, an air guide tube 420 and a ventilation tube 430, the motor 410 is electrically connected to the controller 600, one end of the air guide tube 420 is connected to the first air guide hole 330, and the other end is connected to the first connection port 411 of the motor 410; one end of the ventilation tube 430 is connected to the ventilation hole 112 (such as Figure 2 As shown), the other end is connected to the second connection port 412 of the motor 410.

[0061] Specifically, the inflation and deflation device 400 is installed in the accommodation space, and the motor 410 provides power for the inflation and deflation of the elastic contact member 300. The motor 410 is electrically connected to the controller 600, and the controller 600 controls the operation of the motor 410 according to the pressure value detected by the pressure sensor 310.

[0062] When the pressure value detected by the controller 600 is less than the first preset pressure value, the smart ring needs to be tightened and the elastic contact piece 300 needs to be inflated. The controller 600 controls the motor 410 to provide inflation power. The gas enters the air chamber 320 through the ventilation hole 112, the ventilation tube 430, the second connecting port 412, the first connecting port 411, the air guide tube 420, and the first air guide hole 330, so that the elastic contact piece 300 expands, thereby increasing the height of the elastic contact piece 300 extending out of the adjustment hole 111, thereby achieving the tightening of the smart ring.

[0063] When the pressure value detected by the controller 600 is greater than the second preset pressure value, the smart ring needs to be loosened and the elastic contact piece 300 needs to be deflated. The controller 600 controls the motor 410 to provide deflation power, and the gas in the air chamber 320 is discharged to the outside through the first air guide hole 330, the air guide tube 420, the first connecting port 411, the second connecting port 412, and the ventilation tube 430, so that the elastic contact piece 300 contracts, thereby reducing the height of the elastic contact piece 300 extending out of the adjustment hole 111, thereby achieving the loosening of the smart ring.

[0064] In one embodiment, the controller 600 can control the switching of inflation and deflation by controlling the forward and reverse rotation of the motor 410. In one embodiment, the first air guide hole 330 is provided on the side of the elastic contact member 300. Compared with providing the first air guide hole 330 at the end of the elastic contact member 300, the first air guide hole 330 is avoided from interfering with the finger when the smart ring is worn, and the complex connection path between the first air guide hole 330 and the air guide tube 420 is also avoided. In one embodiment, along the radial direction of the smart ring, the first air guide hole 330 is arranged away from the center of the smart ring, which is conducive to the deflation of the elastic contact member 300. In one embodiment, the air exchange hole 112 is provided on the inner side of the ring body 100, so that when the smart ring is worn, the air exchange hole 112 cannot be observed from the outside, which is conducive to the aesthetics of the smart ring.

[0065] See also Figures 3 to 5 In an embodiment of the present invention, the smart ring further includes a flexible circuit board 500 installed on the ring body 100 , a controller 600 is provided on the flexible circuit board 500 , and the elastic contact piece 300 and the flexible circuit board 500 enclose an air cavity 320 .

[0066] Specifically, the flexible circuit board 500 extends along the circumference of the smart ring and is installed in the accommodation space, and the controller 600 is arranged on the flexible circuit board 500. Along the radial direction of the smart ring, the elastic contact member 300 is located on the inner side of the flexible circuit board 500. The elastic contact member 300 and the flexible circuit board 500 enclose the air-containing cavity 320, that is, the flexible circuit board 500 is the bottom wall of the air-containing cavity 320, thus saving the use area of ​​the elastic contact member 300 and facilitating the electrical connection between the pressure sensor 310 and the controller 600.

[0067] See also Figure 5 In an embodiment of the present invention, a fixed bracket 510 is provided on the flexible circuit board 500, and the elastic contact member 300 is sleeved on the fixed bracket 510, and the two are sealed and connected, and a second air guide hole 511 is provided on the fixed bracket 510, and the second air guide hole 511 is connected to the first air guide hole 330.

[0068] In one embodiment, the fixed bracket 510 is an annular structure with openings at both ends, wherein one open end is fixedly abutted against the flexible circuit board 500, and the elastic contact member 300 is sleeved on the other open end of the fixed bracket 510. The elastic contact member 300 is sleeved outside the fixed bracket 510, and in one embodiment, the two are sealed by a sealant. In this way, the flexible circuit board 500, the fixed bracket 510, and the elastic contact member 300 enclose an air-containing cavity 320, and the air-tightness of the air-containing cavity 320 is ensured. In the air-containing cavity 320, the flexible circuit board 500 is the bottom wall of the air-containing cavity 320, the fixed bracket 510 is the side wall of the air-containing cavity 320, and the elastic contact member 300 is the top wall of the air-containing cavity 320.

[0069] It can be understood that the elastic contact member 300 is a flexible member, and the setting of the fixed bracket 510 provides support for the elastic contact member 300, and also realizes the connection between the elastic contact member 300 and the flexible circuit board 500. In one embodiment, the elastic contact member 300 covers the entire outer wall of the fixed bracket 510, so that the contact area between the elastic contact member 300 and the fixed bracket 510 is increased, the connection stability between the elastic contact member 300 and the fixed bracket 510 is improved, and the connection stability of the elastic contact when it is inflated and subjected to the expansion force is ensured.

[0070] In order to achieve the connection between the air-containing cavity 320 and the air-conducting tube 420, a second air-conducting hole 511 is opened on the fixed bracket 510, and the second air-conducting hole 511 is correspondingly connected with the first air-conducting hole 330, so that the air-conducting tube 420 can be connected with the air-containing cavity 320 through the first air-conducting tube 420 and the second air-conducting tube 420, thereby realizing the inflation and deflation of the elastic contact piece 300.

[0071] See also Figure 2In an embodiment of the present invention, the ring body 100 is provided with an embedding groove 113, and the embedding groove 113 is used to accommodate the air guide tube 420. The provision of the embedding groove 113 provides an installation position for the air guide tube 420, avoids the air guide tube 420 from running around in the accommodation space under the action of external force, and ensures the reliability of the inflation and deflation of the elastic contact member 300. In one embodiment, the embedding groove 113 extends along the circumference of the ring body 100, and the embedding groove 113 is connected to the adjustment hole 111, so that the air guide tube 420 can be completely accommodated in the embedding groove 113, avoiding interference between the air guide tube 420 and other components, and also avoiding friction of other components on the air guide tube 420.

[0072] See also Figure 4 and Figure 5 In an embodiment of the present invention, the flexible circuit board 500 is provided with a connector 520 in the fixing bracket 510, the connector 520 is electrically connected to the controller 600, and the connector 520 is electrically connected to the pressure sensor 310 through a retractable electrical connector.

[0073] Specifically, a connector 520 is provided on the flexible circuit board 500 in the air cavity 320, and the connector 520 is electrically connected to the controller 600. The elastic contact 300 is provided with a pressure sensor 310 on the side facing the inside of the air cavity 320. In one embodiment, the elastic contact 300 is provided with a mounting groove on the side facing the ring body 100, and the pressure sensor 310 is installed in the mounting groove. At this time, the pressure sensor 310 and the connector 520 are both located in the air cavity 320, and the two are electrically connected through a retractable electrical connector, thereby realizing the electrical connection between the pressure sensor 310 and the controller 600.

[0074] It can be understood that as the elastic contact 300 is inflated and deflated, the height of the elastic contact 300 extending out of the adjustment hole 111 is different, that is, the distance between the inner surface of the elastic contact 300 and the flexible circuit board 500 will change accordingly. In order to ensure the electrical connection between the pressure sensor 310 on the elastic contact 300 and the electrical connector 520 on the flexible circuit board 500, a retractable electrical connector is provided between the two. When the elastic contact 300 is inflated, the retractable electrical connector is extended accordingly; when the elastic contact 300 is deflated, the retractable electrical connector is contracted accordingly, thereby ensuring the electrical connection between the pressure sensor 310 and the controller 600.

[0075] See also Figure 4 and Figure 5In an embodiment of the present invention, the electrical connector is configured as a connecting plate 530 having at least one bending portion 531. Thus, when the elastic contact 300 is inflated, the bending portion 531 stretches to increase the length of the connecting plate 530 in the radial direction of the smart ring; when the elastic contact 300 is deflated, the bending portion 531 folds to shorten the length of the connecting plate 530 in the radial direction of the smart ring, thereby ensuring the reliability of the connection between the pressure sensor 310 and the controller 600. Of course, in other embodiments, the electrical connector may also be a flexible wire or the like.

[0076] See also Figure 2 and Figure 3 In an embodiment of the present invention, a plurality of elastic contact members 300 are provided, one elastic contact member 300 corresponds to one adjustment hole 111 , and two air cavities 320 of adjacent elastic contact members 300 are connected through an air guide tube 420 .

[0077] In the scheme shown in the figure of the present invention, four elastic contact members 300 are evenly spaced along the circumference of the smart ring. Correspondingly, four adjustment holes 111 are provided on the ring body 100, and three air guide tubes 420 are provided in the gas charging and discharging device 400, and the three air guide tubes 420 are respectively connected to two adjacent air cavities 320. In this way, the provision of multiple elastic contact members 300 is conducive to the balance of the tightness adjustment of the smart ring, and is also conducive to the wearing comfort of the smart ring. In addition, multiple air guide tubes 420 are provided in the gas charging and discharging device 400, so that the multiple air cavities 320 are all connected, so that the gas charging and discharging adjustment of the multiple elastic contact members 300 can be synchronized.

[0078] Of course, in other embodiments, the number of elastic contact members 300 can also be five or other numbers, and the number of adjustment holes 111 and air guide tubes 420 is set corresponding to the number of elastic contact members 300. Here, the number of elastic contact members 300, adjustment holes 111, and air guide tubes 420 is not limited.

The flexible circuit board 500 is installed in the mounting groove 114, and the elastic contact piece 300 corresponds to the adjustment hole 111; the outer shell 120 is sleeved outside the inner shell 110.

[0082] Specifically, the ring body 100 includes an inner shell 110 and an outer shell 120. The arrangement of the inner shell 110 and the outer shell 120 facilitates the assembly of the smart ring. An adjustment hole 111 is provided on the inner shell 110, and an installation groove 114 is provided on the outer side of the inner shell 110 along its circumference. The flexible circuit board 500 is installed in the installation groove 114, and the elastic contact member 300 on the flexible circuit board 500 corresponds to the adjustment hole 111 one by one. The arrangement of the installation groove 114 facilitates the installation of the flexible circuit board 500 and prevents the flexible circuit board 500 from coming off the inner shell 110. The outer shell 120 is sleeved outside the inner shell 110, and along the radial direction of the smart ring, the outer shell 120 is located between the two side walls of the installation groove 114. The arrangement of the installation groove 114 also provides positioning for the installation of the outer shell 120, thereby improving the assembly efficiency of the inner shell 110 and the outer shell 120.

[0084] Specifically, a switch key 540 is provided on one side of the flexible circuit board 500 away from the center of the smart ring, and pressing the switch key 540 can control the opening of the inflation and deflation of the inflation and deflation device 400. In one embodiment, the switch key 540 is pressed once, and the motor 410 starts the inflation working mode to inflate the elastic contact member 300; the switch key 540 is pressed twice, and the motor 410 starts the deflation working mode to deflate the elastic contact member 300. The matching relationship between the switch key 540 and the motor 410 working mode can be adjusted as needed, and no limitation is made here. In order to realize the pressing of the switch key 540, the shell 120 is configured as a soft rubber material at least at the switch key 540. In this way, the switch key 540 is hidden on the inner side of the shell 120, and the outer side of the switch key 540 is covered with the shell 120 of soft rubber material, which ensures that the switch key 540 can be pressed normally, and is also conducive to the aesthetics of the smart ring.

[0085] In one embodiment, the entire shell 120 is configured to be made of soft rubber material, which is beneficial to the overall consistency of the shell 120, the processing and molding of the shell 120, and the wearing comfort of the smart ring. Of course, in other embodiments, a switch hole can be opened on the shell 120, so that part of the switch key 540 extends out of the switch hole for the user to press and operate.
