Description

Technical Field

[0001] This utility model relates to the field of smart ring technology, and in particular to a smart ring with physical buttons. Background Technology

[0002] Smart rings are currently the smallest mass-produced interactive smart hardware products. They boast numerous advantages, including compact size, light weight, ease of wear, and convenient operation, gradually becoming a popular smart wearable device among consumers. Most smart rings on the market currently employ a buttonless design, primarily relying on the user's touch on the ring's surface and a capacitive sensing chip detecting changes in capacitance to send commands. In this case, the user needs to touch a specific location on the ring to send a command. During wear, the ring inevitably rotates to some extent on the user's finger, causing the touch point to deviate from its initial position. This means the user may need to repeatedly touch the ring to find the touch point, or look down to locate it, causing inconvenience. Furthermore, with touch-based command sending, users are prone to accidentally sending commands by touching the ring unintentionally, interfering with the normal operation of the smart ring. If a button design were used, the size of the ring itself makes it difficult to incorporate a reset mechanism, causing the button to easily become stuck after being pressed, thus affecting normal pressing and use. Utility Model Content

[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing a smart ring with physical buttons that is easy to operate, reduces accidental touches, and provides smooth button presses.

[0004] A smart ring with physical buttons, comprising: The finger ring has a button hole on its ring side that communicates with the inner cavity of the finger ring; A control component, the control component including at least a flexible control circuit board wound around and attached to the inner surface of the ring and a battery electrically connected to the flexible control circuit board, wherein the button pressing position on the flexible control circuit board corresponds to the button hole; The pressing assembly includes an elastic pad located between the inner surface of the finger ring and the flexible control circuit board, sealing the key hole; a keycap passing through the key hole and fixedly connected to the elastic pad; a side of the elastic pad adjacent to the key hole being sealed to the edge of the key hole; and an edge of the elastic pad facing away from the key hole being sealed to the flexible control circuit board to form a deformable closed air chamber; and The inner ring is located inside the finger ring and is fixedly connected to the finger ring. The outer ring side of the inner ring is at least in contact with the side of the flexible control circuit board facing away from the finger ring.

[0005] In one embodiment, the flexible control circuit board includes a main control board that conforms to the inner surface of the finger ring, and a button circuit board that conforms to the inner surface of the finger ring and is sealed to the edge of the button hole. The button circuit board is electrically connected to the main control board and has a button pressing position.

[0006] In one embodiment, the main control board includes an MCU chip, a heart rate sensor and / or an electrocardiogram sensor and / or a temperature sensor electrically connected to the MCU chip, and a vibration motor electrically connected to the MCU chip that vibrates when the keycap is pressed.

[0007] In one embodiment, the ring side of the finger ring has an indicator hole next to the button hole, the indicator hole is filled with a transparent adhesive layer, and the button circuit board has an indicator light corresponding to the indicator hole.

[0008] In one embodiment, the elastic pad includes a first part corresponding to the button hole and a second part fixedly connected to the edge of the first part and corresponding to the indicator hole. The first part is sealed to the edge of the button hole, and the second part is sealed to the edge of the indicator hole. A through hole is provided on the second part. The indicator light passes through the through hole and out of the closed air chamber to align with the indicator hole, and the indicator light is sealed to the inner wall of the through hole.

[0009] In one embodiment, the lower surface of the first portion protrudes at the location corresponding to the button press position to form a press step.

[0010] In one embodiment, the lower surface edge of the first part is provided with at least two concentric barrier structures arranged from the inside out.

[0012] In one embodiment, the upper surface of the elastic pad is provided with a boss, and the lower surface of the keycap is provided with a groove that conforms to the shape of the boss. The keycap is placed on the boss and bonded to the elastic pad.

[0013] In one embodiment, each of the two open edges of the finger ring is provided with a retaining ring, and the outer ring surface of the retaining ring is fixedly connected to the inner surface of the finger ring.

[0014] This invention relates to a smart ring with physical buttons. A pressing component is installed on the ring band. Pressing the button sends commands to a flexible control circuit board, enabling interaction between the user and the smart ring. Users can locate the button by touching it with their fingers, allowing for blind operation and reducing the difficulty of using the ring. The requirement to press the button triggers commands, reducing accidental touches caused by traditional sensor designs. A deformable sealed air chamber is formed between the elastic pad and the flexible control circuit board. When the button is pressed, the gas inside the sealed air chamber below the button is compressed to the rest of the chamber, and the elastic pad deforms. When the button is released, the elastic pad returns to its original position and pushes the gas back under the button, causing the gas to push the elastic pad and lift the button. This prevents the button from jamming, ensuring smooth button pressing and improving the user experience. Attached Figure Description

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please combine Figure 1-6 This utility model discloses a smart ring 10 with physical buttons that is easy to operate, reduces accidental touches, and provides smooth button pressing. The smart ring includes a ring 100, a control component, a pressing component, and an inner ring 200. The ring 100 has a button hole 110 on its side that communicates with the inner cavity of the ring 100. The control component includes at least a flexible control circuit board 300 wound around and fitted to the inner surface of the ring 100, and a battery 400 electrically connected to the flexible control circuit board 300. The button pressing position on the flexible control circuit board 300 corresponds to the button hole 110. The battery 400 provides the operating voltage for the smart ring. When using the smart ring, the user can operate the pressing component to start the smart ring as needed, avoiding the problem of rapid power consumption caused by prolonged operation and extending the smart ring's battery life. The pressing assembly includes an elastic pad 500 located between the inner surface of the finger ring 100 and the flexible control circuit board 300, sealing the key hole 110; a keycap 600 passing through the key hole 110 and fixedly connected to the elastic pad 500; the side of the elastic pad 500 adjacent to the key hole 110 is sealed to the edge of the key hole 110; the edge of the elastic pad 500 facing away from the key hole 110 is sealed to the flexible control circuit board 300 to form a deformable closed air chamber 700; an inner ring 200 is located inside the finger ring 100 and fixedly connected to the finger ring 100; the outer ring side of the inner ring 200 is at least in contact with the side of the flexible control circuit board 300 facing away from the finger ring 100. In other words, the finger ring 100 and the inner ring 200 jointly encapsulate the flexible control circuit board 300 to achieve fixation and protection of the flexible control circuit board 300. Because the elastic pad 500 is used in conjunction with the flexible control circuit board 300, in order to meet the deformability requirements of the closed air chamber 700, at least a portion of the area on the elastic pad 500 located around the key hole 110 is not sealed to the edge of the key hole 110 and the flexible control circuit board 300, so that this portion can deform when the gas flows in the closed air chamber 700, so that the gas can migrate to the deformed part, thereby providing conditions for the keycap 600 to be pressed down and lifted back.

[0018] The aforementioned smart ring 10 with physical buttons has a pressing component on the ring 100. By pressing the keycap 600, commands are sent to the flexible control circuit board 300 to enable interaction between the consumer and the smart ring. When using the smart ring, the consumer can determine the button position by touching the keycap 600 with their finger, providing conditions for blind operation of the smart ring and reducing the difficulty of operating the smart ring. Since the corresponding command can only be triggered by pressing the keycap 600, it can reduce the accidental touch problem caused by the original sensing design. A deformable closed air chamber 700 is formed between the elastic rubber pad 500 and the flexible control circuit board 300. When the key is pressed, the gas located below the keycap 600 in the closed air chamber 700 is squeezed to the rest of the closed air chamber 700, and the elastic rubber pad 500 deforms. When the keycap 600 is released, the elastic rubber pad 500 returns to its original position and springs back, pressing the gas back under the keycap 600. This causes the gas to push the elastic rubber pad 500 and lift the keycap 600, preventing the keycap 600 from getting stuck and ensuring smooth keycap pressing, which helps improve the user experience.

[0019] Please see Figure 3 The ring 100 provides support for the other components and gives the smart ring its appearance. In this embodiment, the ring 100 has a circular structure and is made of titanium alloy. This design ensures the ring 100's mechanical strength while reducing its weight, thus improving wearer comfort. The thickness of the ring 100 is less than or equal to 0.3 mm. Preferably, the ring 100 has a thickness of 0.3 mm. Each end of the ring 100 has a retaining ring 120 at its open edge. The outer surface of the retaining ring 120 is fixedly connected to the inner surface of the ring 100, and the side of the retaining ring 120 facing away from the inner cavity of the ring 100 is flush with the end face of the ring 100. The end face edge of the ring 100 has rounded corners to prevent scratching the wearer or objects. Through the cooperation of the ring 100 and the retaining rings 120 on both sides, the flexible control circuit board 300 inside the ring 100 can be positioned. Depending on the design of the smart ring, the key hole 110 can be a round hole, an oval hole, a racetrack-shaped hole, or other shapes. The shape of the side of the keycap 600 ring is adapted to the shape of the key hole 110. The gap width between the side of the keycap 600 ring and the inner side of the key hole 110 is between 0.5-2mm. While ensuring that the keycap 600 can be pressed normally, it can reduce the amount of impurities that enter between the elastic pad 500 and the finger ring 100 through this gap, and avoid impurities interfering with the pressing of the keycap 600.

[0020] The flexible control circuit board 300 can be made entirely of a flexible substrate, with corresponding circuit elements disposed on the flexible substrate. Alternatively, multiple rigid substrates can be connected by a flexible strip, with corresponding circuit elements disposed on the rigid substrate, to satisfy the fitting of the flexible control circuit board 300 onto the inner surface of the finger ring 100. In one embodiment, the flexible control circuit board 300 includes a main control board 310 that fits onto the inner surface of the finger ring 100, and a button circuit board 320 that fits onto the inner surface of the finger ring 100 and is sealed to the edge of the button hole 110. The button circuit board 320 is electrically connected to the main control board 310, and the button circuit board 320 has a button pressing position, which is a spring-loaded switch disposed on the button circuit board 320. This can also be understood as follows: the control circuit board used to collect the trigger signal when the keycap 600 is pressed is set separately from the main control board 310 used to control the operation of the whole machine. In this way, even if the diameter of the finger ring 100 is changed to accommodate different finger sizes of consumers, under the premise of ensuring that the key circuit board 320 and the main control board 310 are electrically connected, the positions of the key circuit board 320 and the main control board 310 on the inner surface of the finger ring 100 can be adjusted so that the key pressing position on the key circuit board 320 is aligned with the key hole 110. At the same time, the corresponding sensor set on the main control board 310 can correspond to the corresponding position on the finger (such as the position in the middle of the fingertip) so as to accurately and reliably collect human physiological parameters. In this embodiment, the end of the button circuit board 320 is provided with a strip-shaped electrical connecting piece 321. The button circuit board 320 is electrically connected to the main control board 310 through the strip-shaped electrical connecting piece 321. It can also be connected to the main control board 310 through different parts of the strip-shaped electrical connecting piece 321 to adapt to different installation positions of the main control board 310 and the button circuit board 320, so as to improve the adaptability of the main control board 310 and the button circuit board 320 to different models of smart rings.

[0021] In one embodiment, the main control board 310 is equipped with an MCU chip, a heart rate sensor and / or an electrocardiogram sensor and / or a temperature sensor electrically connected to the MCU chip, and a vibration motor electrically connected to the MCU chip that vibrates when the keycap 600 is pressed. The MCU chip, heart rate sensor, electrocardiogram sensor, temperature sensor, and vibration motor are all disposed on the side of the main control board 310 facing away from the inner surface of the ring 100, and the entire side of the main control board 310 facing the ring 100 is covered with an insulating layer. The heart rate sensor, electrocardiogram sensor, and temperature sensor are used to collect human physiological parameters so that consumers can understand their own health status. The vibration motor is used for operational feedback when the consumer presses the keycap 600; the vibration motor can be a linear vibrator, a piezoelectric ceramic vibrator, or other commercially available micro-vibrators of a size adaptable to a ring. In this embodiment, the main control board 310 or the button circuit board 320 may also be equipped with an NFC chip and / or a Bluetooth chip. In this way, when the consumer uses the smart ring, other smart devices with NFC and Bluetooth functions can be brought close to the smart ring so that the consumer can obtain data collected by the heart rate sensor, ECG sensor and temperature sensor, etc. At the same time, the battery 400 can be charged through the NFC chip to ensure that the smart ring can continue to run.

[0022] In addition, in this embodiment, an indicator hole 130 is provided on the side of the ring 100 next to the button hole 110. The indicator hole 130 is filled with a transparent adhesive layer. The diameter of the indicator hole 130 is 0.5mm. The transparent adhesive layer is obtained by filling the indicator hole 130 with transparent adhesive and curing it. The transparent adhesive can be epoxy resin or other transparent and easy-to-cure adhesives. The button circuit board 320 is provided with an indicator light corresponding to the indicator hole 130. In this way, when the consumer uses the smart ring, they can understand the working status of the smart ring according to the color indicated by the indicator light. For example, when the indicator light is red, it indicates that the smart ring is low on power; when the indicator light is blue, it indicates that the smart ring is pairing with an external smart device; when the indicator light is green, it indicates that the smart ring is working normally. The transparent adhesive layer not only ensures the projection effect of the light emitted by the indicator light, but also seals the indicator hole 130 to prevent external water from entering the smart ring through the indicator hole 130, thus achieving waterproofing of the indicator hole 130. In addition, in this embodiment, the key press positions and indicator lights on the key circuit board are all located in a sealed air chamber, which can effectively insulate the key circuit board from the finger ring and ensure the waterproof effect after the smart ring is assembled. The elastic pad 500 is used on one hand to install the keycap 600 on the finger ring 100, and on the other hand, it also cooperates with the key circuit board 320 to form a sealed air chamber 700. In this embodiment, the elastic pad 500 is a silicone pad, and it is bonded to the edges of the key hole 110 and the indicator hole 130 with waterproof double-sided adhesive to achieve a sealed fit. The keycap 600 is made of plastic or metal to ensure its structural strength and prevent deformation after frequent pressing, thereby extending its service life. Further, please refer to... Figure 4 , Figure 7 as well as Figure 9The upper surface of the elastic pad 500 is provided with a protrusion 510, and the lower surface of the keycap 600 is provided with a groove 610 that conforms to the shape of the protrusion 510. The keycap 600 covers the protrusion 510 and is bonded to the elastic pad 500. In this way, by providing a protrusion 510 on the elastic pad 500, the keycap 600 can be pre-positioned to prevent the keycap 600 from shifting during the bonding process with the elastic pad 500, ensuring accurate alignment between the keycap 600 and the key pressing position on the key circuit board 320. In addition, by providing a protrusion 510 on the elastic pad 500 and a groove 610 on the keycap 600, the bonding area between the elastic pad 500 and the keycap 600 is increased, further improving the stability of the connection between the elastic pad 500 and the keycap 600. In this embodiment, when assembling the keycap 600 and the elastic pad 500, adhesive can be applied to the boss 510 first, and then the keycap 600 can be placed on the boss 510 of the elastic pad 500. After the adhesive cures, the keycap 600 and the elastic pad 500 are fixedly connected. The keycap 600 and the elastic pad 500 can be assembled using fast-drying adhesive, UV adhesive, or heat-drying adhesive to ensure pull-out strength and improve the stability of the connection between the keycap 600 and the elastic pad 500.

[0023] Furthermore, in this embodiment, the elastic pad 500 includes a first portion 501 corresponding to the button hole 110 and a second portion 502 fixedly connected to the edge of the first portion 501 and corresponding to the indicator hole 130. The first portion 501 is sealed to the edge of the button hole 110, and the second portion 502 is sealed to the edge of the indicator hole 130. A through hole 520 is provided on the second portion 502. The indicator light passes through the through hole 520 and exits the sealed air chamber 700 to align with the indicator hole 130, and the indicator light is sealed to the inner wall of the through hole 520. Thus, while the first portion 501 waterproofs the edge of the button hole 110, the second portion 502 can simultaneously waterproof the indicator hole 130, preventing water leakage caused by insufficient sealing of the transparent adhesive layer at the indicator hole 130. In addition, since there may be exposed solder pads on both sides of the indicator light (LED beads in this embodiment) on the button circuit board 320, the second part 502 is provided on the side of the first part 501. On the one hand, the solder pads of the indicator light can be waterproofed. On the other hand, the alignment of the indicator hole 130, the through hole 520 and the indicator light can be achieved by positioning the first part 501 with the edge of the button hole 110, effectively eliminating tolerance accumulation.

[0024] Please combine Figure 4 as well as Figure 7-8The lower surface of the first part 501 protrudes at the corresponding key pressing position to form a pressing step 530. The pressing step 530 has a frustum-shaped structure so that when the elastic pad 500 is squeezed by the keycap 600, it can further squeeze the key circuit board 320 through the pressing step 530 to obtain the key pressing position. This allows the keycap 600 to trigger the key pressing position and send a command to the key circuit board 320 with a small stroke. In this embodiment, the inner ring 200 is formed by potting and curing adhesive inside the ring 100. Thus, during the assembly of the smart ring, the surface of the elastic pad 500 is first adhered to the inner surface of the ring 100 using waterproof double-sided adhesive, and the edge of the elastic pad 500 is glued to the edge of the button circuit board 320 for a sealed connection, forming a closed air chamber 700 to achieve the pre-positioning of the elastic pad 500. Subsequently, the battery 400 and the main control board 310 are installed on the inner surface of the ring 100, and the inner side of the ring 100 is potted and cured to obtain the inner ring 200, which is fixedly connected to the ring 100 and positions the main control board 310, the button circuit board 320, and the battery 400. In this case, the bonding and sealing between the elastic pad 500 and the edge of the button hole 110 effectively prevents the seepage of water, sweat, etc., through the edge of the button hole 110. In addition, in this embodiment, the inner ring 200 is obtained by potting and curing a transparent adhesive. In this way, on the one hand, the various devices on the main control board 310 are positioned by potting to prevent the circuit components from becoming loose. On the other hand, the use of transparent adhesive allows the light emitted by the photoelectric sensors on the main control board 310 to penetrate the inner ring and reach the skin, which is conducive to the effective collection of human physiological parameters.

[0025] In this embodiment, the lower surface edge of the first part 501 is provided with at least two rings of barrier structures arranged from the inside out. The barrier structure includes a number of blocks 540 arranged around the pressing step 530 and spaced apart. An airflow channel 550 is formed between adjacent blocks 540, and the airflow channels 550 of adjacent barrier structures are staggered. In this embodiment, by providing a barrier structure on the lower surface of the first part 501, on the one hand, it can prevent adhesive from entering the area below the keycap 600 on the lower surface of the elastic pad 500 during the bonding process between the elastic pad 500 and the key circuit board 320, thus avoiding interference with the downward pressing of the key after the adhesive cures; on the other hand, the airflow channel 550 on the barrier structure also provides a flow channel for gas during the downward and upward pressing of the keycap 600. When the keycap 600 is pressed down, the gas in the area below the keycap 600 in the sealed air chamber 700 can flow to the edge and the area below the indicator hole 130 through the airflow channel 550, while squeezing the elastic pad 500 to deform; after the keycap 600 is released, this part of the gas flows back to the area below the keycap 600 along the airflow channel 550 during the reset process of the elastic pad 500, thereby pushing up the keycap 600 and realizing the reset and rise of the keycap 600.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
