[0036] The present invention provides a smart finger sleeve 100 .

[0037] See also Figure 1 The embodiment of the smart cuff 100 includes a cuff body 1, a retractable structure 2 and a control component 4. The cuff body 1 has a wearing cavity 11 for inserting a finger, the retractable structure 2 is arranged at the opening end of the wearing cavity 11, and the control component 4 includes a control chip 43 and at least one sensor arranged on the cuff body 1. The control chip 43 drives the retractable structure to expand or tighten according to a signal from the sensor, so as to tighten or loosen the opening end.

[0038] When in use, the smart finger sleeve 100 is worn on the fingertips and connected to smart electronic devices such as AR, VR, smart phones and laptops, so that the finger's left swipe, right swipe, up swipe, down swipe and vertical hit and other actions are transmitted to the smart electronic devices, thereby triggering the smart electronic devices to execute corresponding instructions. Specifically, one end of the finger sleeve body 1 is provided with a wearing port connected to the wearing cavity 11, and the user's finger can be inserted into the wearing cavity 11 through the wearing port. In order to prevent the finger sleeve body 1 from falling off the user's fingertips during use, the open end of the finger sleeve body 1 is provided with a retractable structure 2, such as an elastic band and a rubber band, etc. This type of retractable structure 2 has a first state of tightening the open end and a second state of relaxing the open end, and can switch between the first state and the second state.

[0039] In order to realize the switching of the retractable structure 2 between the first state and the second state, the smart finger sleeve 100 also includes a control component 4 and a driving mechanism 3 arranged on the finger sleeve body 1. The driving mechanism is used to drive the retractable structure 2 to expand or tighten. The control chip 43 is electrically connected to the sensor and the driving mechanism 3, and the control chip 43 is configured to control the action of the driving mechanism according to the signal fed back by the sensor, thereby tightening or loosening the opening end.

[0040] Specifically, when the smart finger sleeve 100 needs to be worn, the retractable structure 2 is in the second state, which is convenient for the user to insert the finger into the wearing cavity 11. When the sensor senses that it is worn in place, the control chip 43 controls the drive mechanism to act, and the drive mechanism drives the retractable structure 2 to tighten, and then switches the retractable structure 2 to the first state to clamp the finger in the wearing cavity 11, thereby preventing the smart finger sleeve 100 from falling off the user's fingertips and ensuring the stability of wearing. When the smart finger sleeve 100 needs to be removed from the finger, press the sensor, the control chip 43 will control the drive mechanism to act, and the drive mechanism drives the retractable structure 2 to expand, so that the retractable structure 2 is switched back to the second state again to release the finger in the wearing cavity 11, so as to facilitate the removal of the smart finger sleeve 100.

[0041] In some embodiments of the present invention, the retractable structure 2 is a retractable strip, which is arranged around the circumference of the opening end. The retractable strip has a first end 21 and a second end 22. In the initial state, that is, when the smart finger sleeve 100 is not worn on the finger, the first end 21 and the second end 22 may be arranged to overlap or not overlap.

[0042] For example, in one embodiment, the first end 21 and the second end 22 do not overlap, that is, the first end 21 and the second end 22 are separately arranged, and the retractable strip does not form a closed ring. At this time, the first end 211 is configured so that its end face can approach or move away from the end face of the second end 22. If a traction rope is connected to the first end 21 and / or the second end 22, the drive mechanism can pull the traction rope to make the end face of the first end 21 and the end face of the second end 22 approach each other. At this time, the retractable strip performs a contraction movement, the opening of the wearing cavity is tightened, and the end face of the first end 21 and the end face of the second end 22 can be released to make the end face of the first end 21 and the end face of the second end 22 approach each other. At this time, the control chip 43 drives the drive mechanism to operate according to the signal from the sensor, thereby driving the end face of the first end 21 and the end face of the second end 22 to gradually approach or gradually move away.

[0043] The first end 21 and the second end 22 may not overlap at all times, that is, the end surface of the first end 21 and the end surface of the second end 22 are always separated. When the retractable strip is in a relaxed state, the end surface of the first end 21 and the end surface of the second end 22 are far apart. When the retractable strip is in a tightened state, the end surface of the first end 21 and the end surface of the second end 22 are close together. Alternatively, the first end 21 and the second end 22 may move from a mutually separated state to a gradually overlapping state, thereby tightening the opening of the wearing cavity, and then move from the overlapping state to a separated state, thereby loosening the opening of the wearing cavity.

[0044] In another embodiment, the first end 21 and the second end 22 are always overlapped, and a driving mechanism 3 is arranged between the first end 21 and the second end 22, and the driving mechanism 3 is used to drive the end surface of the first end 21 and the end surface of the second end 22 to gradually approach or gradually move away.

[0045] Specific reference Figure 2 The first end 21 is provided with a first rack 211, and the second end 22 is provided with a second rack 221. The driving mechanism 3 includes a gear 32 and a motor 31 for driving the gear 32 to rotate. The gear 32 is meshed with the first rack 211 and the second rack 221, so that the end surface of the first end 21 and the end surface of the second end 22 can be driven to gradually approach or gradually move away from each other by rotating the driving gear 32.

[0046] In the initial state, the edge positions of the first rack 211 and the second rack 221 are meshed with the gear 32. At this time, the overlapping area of ​​the first end 21 and the second end 22 is the smallest, and the opening of the wearing cavity 11 is the largest. When the user inserts the finger into the wearing cavity 11, the gear 32 rotates clockwise, and the rotation of the gear 32 will drive the first end 21 and the second end 22 to move in an offset manner, and the overlapping area of ​​the first end 21 and the second end 22 gradually increases, and the end face of the first end 21 and the end face of the second end 22 gradually move away, and the opening of the wearing cavity 11 gradually tightens, thereby clamping the finger in the wearing cavity 11. When the smart finger sleeve 100 needs to be removed from the finger, the gear 32 is controlled to rotate in the opposite direction, and the gear 32 rotates in the opposite direction to drive the first end 21 and the second end 22 to move in the opposite direction, and the overlapping part of the first end 21 and the second end 22 gradually decreases, and the end face of the first end 21 and the end face of the second end 22 gradually approach, and the opening of the wearing cavity 11 gradually becomes larger, so as to facilitate the removal of the smart finger sleeve 100.

[0047] Among them, the finger sleeve body 1 is made of soft rubber material at least in part of the opening end, that is, the finger sleeve body 1 can be made of soft rubber material as a whole, or the finger sleeve body 1 is made of soft rubber material in part of the opening end, and other areas are made of plastic material with a certain hardness, so as to ensure that the opening end of the finger sleeve body has shrinkage and deformation performance. The retractable strip can be bonded or sewn on the surface of the finger sleeve body 1, or the retractable strip can be built into the finger sleeve body 1, that is, a matching gap is set in the peripheral wall of the finger sleeve body 1, the matching gap ring is set at the opening end of the finger sleeve body, and the retractable strip can be movably set in the matching gap.

[0048] In one embodiment, the control component 4 includes a control chip 43 and a single sensor. At this time, the control chip 43 is electrically connected to the single sensor and the driving mechanism, and the control chip 43 drives the gear 32 to rotate according to the signal fed back by the single sensor.

[0049] For example, the sensor is a pressure sensor. When the sensor senses the first tap of the finger, the control chip 43 controls the gear 32 to rotate to tighten the retractable strip; when the sensor senses the second tap of the finger, the control chip 43 controls the gear 32 to stop rotating, and the retractable strip stops shrinking; when the sensor senses the third tap of the finger, the control chip 43 controls the gear 32 to rotate in the opposite direction to loosen the retractable strip; when the sensor senses the fourth tap of the finger, the control chip 43 controls the gear 32 to stop rotating, and the retractable strip stops loosening. Alternatively, the control chip 43 can control the forward rotation, reverse rotation, and stop of the gear 32 according to the number of consecutive taps sensed by the sensor, such as if the gear 32 is tapped twice in a row, the control chip 43 controls the gear 32 to rotate forward, and if the gear 32 is tapped three times in a row, the control chip 43 controls the gear 32 to rotate in the opposite direction; if the gear 32 is tapped once, the control chip 43 controls the gear 32 to stop rotating.

[0050] In another embodiment, the control component 4 includes a control chip 43 and two sensors, namely a first sensor 41 and a second sensor 42. The first sensor 41 and the second sensor 42 are both pressure sensors. The first sensor 41 is arranged at the tip of the cuff body 1, and the second sensor 42 is arranged at the open end of the cuff body 1. The control chip 43 is electrically connected to the first sensor 41, the second sensor 42 and the driving mechanism 3. The control chip 43 controls the gear 32 to rotate according to the signal fed back by the first sensor 41, and controls the gear 32 to stop rotating according to the signal fed back by the second sensor 42.

[0051] Reference Figures 3 to 7 In order to facilitate the installation and connection of the second sensor 42 and the control chip 43, the control component also includes a first circuit board 46, which is arranged on the side of the finger sleeve body 1 facing the back of the finger, and the second sensor 42 and the control chip 43 are both arranged on the first circuit board 46.

[0052] In this embodiment, the second sensor 42 and the control chip 43 are both arranged on the side of the finger sleeve body 1 facing the back of the finger. Since the back of the finger is relatively stable during the movement of the finger and is not as easily wrinkled or deformed as the fingertip due to the bending of the finger, it helps to maintain the stability of the second sensor 42 and the control chip 43, thereby avoiding misoperation.

[0053] Specifically, the first circuit board 46 includes a main control part 461, a first connection part 462 and a second connection part 463. The main control part 461 is arranged on the side of the finger sleeve body 1 facing the back of the finger and close to the fingertip. One end of the first connection part 462 is connected to the main control part 461, and the other end of the first connection part 462 extends to the open end. One end of the second connection part 463 is connected to the main control part 461 or the first connection part 462, and the other end of the second connection part 463 extends to the open end. The first circuit board 46 can be made of PCB or FPC as a whole, or the main control part 461 is made of PCB, and the first connection part 462 and the second connection part 463 are made of FPC, which is not limited here.

[0054] The driving mechanism 3 further includes a motor 31 connected to the gear 32, one of the motor 31 and the second sensor 42 is arranged at one end of the first connecting portion 462 away from the main control portion 461, and the other is arranged at one end of the second connecting portion 463 away from the main control portion 461, and the control chip 43 is arranged on the main control portion 461. The motor 31 and the second sensor 42 can be fixed to the end of the first connecting portion 462 or the second connecting portion 463 by screws or glue. In this way, the control chip 43, the driving mechanism 3 and the second sensor 42 can be connected as a whole.

[0055] Furthermore, the control component 4 further includes a second circuit board 47, which is electrically connected to the first circuit board 46. The second circuit board 47 is disposed at the tip of the cuff body 1 and is located on the side of the cuff body 1 facing the finger pulp, and the first sensor 41 is disposed on the second circuit board 47. Thus, the control chip 43, the drive mechanism 3, the first sensor 41 and the second sensor 42 can be connected as a whole.

[0056] When the smart finger sleeve 100 is not worn on the finger, the first sensor 41 and the second sensor 42 do not feel any pressure. At this time, the gear 32 rotates to the initial position, the edge positions of the first rack 211 and the second rack 221 are meshed with the gear 32, and the opening of the wearing cavity 11 is in the maximum state, which is convenient for the user to insert the finger into the wearing cavity 11. After the user inserts the finger into the wearing cavity 11, the user's fingertip will contact and press the first sensor 41, and the first sensor 41 will feel the pressure and transmit the pressure signal to the control chip 43. The control chip 43 receives the signal sent by the first sensor 41 and then drives the motor 31 to drive the gear 32 thereon to rotate clockwise, thereby driving the end face of the first end 21 and the end face of the second end 22 of the retractable strip to gradually move away, that is, the retractable strip performs a contraction movement, thereby driving the opening of the wearing cavity 11 to gradually shrink. During this process, the second sensor 42 gradually moves towards the user's finger. When the second sensor 42 feels pressure, it indicates that the opening end of the wearing cavity 11 has shrunk to a state where the finger can be clamped. At this time, the second sensor 42 transmits the pressure signal to the control chip 43. The control chip 43 will control the first sensor 41 to stop working and control the gear 32 to stop rotating to prevent the opening of the wearing cavity 11 from shrinking too tightly.

[0057] When the smart finger sleeve 100 needs to be removed from the finger, the first sensor 41 or the second sensor 42 can be pressed again, and the first sensor 41 or the second sensor 42 will transmit the pressure signal to the control chip 43 again. The control chip 43 will drive the motor 31 to drive the gear 32 thereon to rotate counterclockwise, thereby driving the end face of the first end 21 and the end face of the second end 22 of the retractable strip to gradually approach each other, and the opening of the wearing cavity 11 will gradually expand, thereby releasing the finger in the wearing cavity 11, making it convenient to remove the smart finger sleeve 100.

[0058] Reference Figure 8 In the present invention, in order to hide the driving mechanism 3, the smart finger sleeve 100 also includes a sealed shell 5, the driving mechanism 3 is arranged in the sealed shell 5, the first end 21 and the second end 22 are respectively penetrated through the sealed shell 5 to engage with the gear 32, and the first connecting part 462 or the second connecting part 463 is penetrated through the sealed shell 5 to connect with the motor 31.

[0059] Reference Figure 3 and Figure 4The sealing housing 5 includes an upper sealing cover 51 and a lower sealing cover 52, and the upper sealing cover 51 and the lower sealing cover 52 are detachably connected, such as a snap connection or a magnetic connection. During assembly, the upper sealing cover 51 and the lower sealing cover 52 are opened, and then the first end 21 of the retractable strip is placed in the lower sealing cover 52, and then the gear 32 is installed to mesh with the first rack 211, and then the second rack 221 is meshed with the gear 32, and finally the upper sealing cover 51 and the lower sealing cover 52 are buckled and fixed, and finally the retractable strip, the control assembly and the sealing housing 5 are fixed on the finger sleeve body.

[0060] In one embodiment, the retractable strip, the driving mechanism 3, the control component 4 and the sealing shell 5 are all built into the finger sleeve body 1. That is, the retractable strip, the driving mechanism 3, the control component 4 and the sealing shell 5 are all embedded in the finger sleeve body 1 by in-mold injection molding, thereby ensuring the neatness and beauty of the appearance of the smart finger sleeve. In particular, in order to ensure that the retractable strip can move relatively in the finger sleeve body 1, there is a matching gap between the retractable strip and the finger sleeve body 1. Specifically, before the finger sleeve body 1 is injection molded, a coating is applied around the retractable strip to prevent the retractable strip from bonding with the finger sleeve body 1, so that the finger sleeve body 1 and the retractable strip are in a separated state after molding.

[0061] Furthermore, in the present smart cuff 100, the control component 4 also includes an OFN module 45, which is disposed on the cuff body 1 and is used to sense the user's finger movements. Specifically, the OFN module 45 is disposed on the side of the second circuit board 47 that is away from the wearing cavity 11, that is, the OFN module 45 is disposed at the tip of the cuff body 1 and is located on the side of the cuff body 1 that faces the finger pulp. The OFN module is an optical finger navigation module (Optical Finger Navigation, OFN), and its working principle is similar to that of an optical mouse. When a finger moves on the surface of the OFN module, the OFN module can detect the movement signal of the finger and generate corresponding control instructions according to the movement speed and direction of the finger. At present, the OFN module is a mature technology and will not be described in detail here.

[0062] In one embodiment, the second circuit board 47 and the OFN module 45 are both built into the finger sleeve body 1. At this time, a light-transmitting area is provided on the surface of the finger sleeve body 1, and the light-transmitting area is arranged opposite to the OFN module 45. The material used in the light-transmitting area can transmit the infrared light emitted by the OFN module, such as acrylic and PET, so as to ensure that the infrared light emitted by the OFN module 45 can irradiate the finger, so as to realize the capture of the finger movement.

[0063] In addition, the control component 4 also includes a Bluetooth chip 44, which is arranged on the first circuit board 46 and is used for wireless connection with smart electronic devices such as AR, VR, smart phones and laptops, so as to realize the action interaction between the smart finger cuff and the smart electronic devices.

[0064] It should be noted that this smart finger sleeve can be worn on a single finger, and other fingers can be used to touch the OFN module on it to control commands. For example, when the finger swipes left, right, up, down, and vertically in the OFN module area, the optical chip in the OFN module can successfully capture the action information and convert this information into corresponding actions in the application scenario. For example, the vertical swiping action can correspond to functions such as click, confirm, or lock, which can be set according to needs.

[0065] Alternatively, the smart finger sleeve can be worn on multiple fingers. In this case, the offset movement of the two OFN modules can define completely different functions, such as scrolling up, scrolling down, scrolling left, scrolling right, etc., which can be set according to specific needs.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
