Detailed Description of the Embodiments
[0018] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.
[0019] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.
[0020] Next, with reference to the accompanying drawings, a wrist device 100 according to an embodiment of the present application will be described.
[0021] As Figure 1 shown, the wrist device 100 may include: a wristband body 1, an adjustment assembly 2, and a tightening band 3.
[0022] As Figure 1 shown, the wristband body 1 is wound into an open-ring shape 11. Specifically, the wristband body 1 is adapted to surround the human wrist. Since the wristband body 1 is in the shape of an open ring 11, the size of the opening 11 can be adjusted to effectively fit wrists of different thicknesses. Exemplarily, the wrist device 100 of the embodiment of the present application is an electromyogram detection wristband. Electrodes are provided on the inner circumferential surface of the wristband body 1, and a circuit, a chip, etc. are built into the wristband body 1 to implement electromyogram detection. If the size of the wristband body 1 is larger than the size of the human wrist, the electrodes on the inner circumferential surface of the wristband body 1 cannot be reliably attached to the human wrist, affecting the reliability of electromyogram detection. And if the size of the wristband body 1 is too small compared to the size of the human wrist, it will be worn too tightly, causing discomfort to the user.
[0023] As Figure 1 shown, the adjustment assembly 2 is provided on the wristband body 1 and is located in the outer ring area of the wristband body 1. The adjustment assembly 2 includes two reels 21 spaced apart along the width direction of the wristband body 1. The adjustment assembly 2 is used to drive the two reels 21 to rotate. There are two tightening bands 3 spaced apart along the width direction of the wristband body 1. Each tightening band 3 surrounds the wristband body 1 and both ends are connected to the corresponding reel 21 on that side. The tightening band 3 is shortened or lengthened by the rotation of the reel 21 to adjust the size of the opening 11. Among them, the tightening band 3 restricts the opening 11 of the wristband body 1 to become smaller by shortening, and the tightening band 3 releases the opening 11 of the wristband body 1 to become larger by lengthening. Or rather, when the tightening band 3 is shortened, it can restrict the opening 11 of the wristband body 1 to decrease, and when the tightening band 3 is lengthened, it can relax the opening 11 of the wristband body 1 to become larger.
[0024] Exemplarily, the two width sides of the wristband body 1 are respectively a first side 12 and a second side 13. The two reels 21 are respectively a first reel 211 disposed close to the first side 12 and a second reel 212 disposed close to the second side 13. The two tightening bands 3 are respectively a first tightening band 31 disposed close to the first side 12 and a second tightening band 32 disposed close to the second side 13. Both ends of the first tightening band 31 are connected to the first reel 211, and both ends of the second tightening band 32 are connected to the second reel 212. When the first reel 211 rotates, the first tightening band 31 shortens or lengthens. When the second reel 212 rotates, the second tightening band 32 shortens or lengthens.
[0025] Thus, by setting the cooperation of the adjusting assembly 2 and the tightening band 3, the size of the opening 11 of the wristband body 1 can be adjusted to adapt to the effective wearing of wrists of different thicknesses. Moreover, since there are two tightening bands 3 and they are spaced along the width direction of the wristband body 1, the wristband body 1 can be better fitted to the wrist in the entire width direction through the restraint of the two tightening bands 3, improving the reliability of EMG detection. In addition, since there are two tightening bands 3, the tension of each tightening band 3 is relatively small, so the width of each tightening band 3 can be reduced. In this way, when the two tightening bands 3 are spaced along the width direction of the wristband body 1, the covering area of the tightening bands 3 on the wristband body 1 can be reduced, which is beneficial to the heat dissipation of the wristband body 1 and improves the working reliability of the wristband body 1.
[0026] In some embodiments of the present application, as Figure 1 shown, the wristband body 1 has a through-hole 141, and the tightening band 3 is threaded through the through-hole 141. Thus, the tightening band 3 can be threaded through the wristband body 1, thereby improving the reliability of the cooperation between the tightening band 3 and the wristband body 1, preventing the tightening band 3 from detaching from the wristband body 1, and enabling the tightening band 3 to effectively and reliably adjust the size of the wristband body 1.
[0027] In some embodiments of the present application, as Figure 1 shown, the outer wall of the wristband body 1 has a rib 14, and the through-hole 141 penetrates the rib 14. Thus, the setting of the rib 14 does not occupy the inner ring area of the wristband body 1 and will not cause interference to the wrist, ensuring the wearing comfort. Moreover, since the rib 14 is provided to process the through-hole 141, the through-hole 141 does not need to penetrate the two surface layers of the thickness of the wristband body 1, so that the tightening band 3 can be completely located in the outer ring area of the wristband body 1, avoiding problems such as the tightening band 3 contacting and interfering with the wrist, and avoiding the tightening band 3 occupying the space for setting electrodes. In addition, when the wristband body 1 is configured to include an outer wristband 16 and an inner wristband 17 described later, since the through-hole 141 does not penetrate the two surface layers of the thickness of the wristband body 1, the sealing performance and waterproof performance of the wristband body 1 can be improved, and the reliability of the wrist device 100 can be enhanced.
[0028] In some embodiments of the present application, as Figure 1 shown, a plurality of ribs 14 are provided on the outer wall of the wristband body 1 at intervals along the length direction of the wristband body 1. Thus, the tightening band 3 can sequentially pass through the through holes 141 on the plurality of ribs 14, thereby further improving the reliability of the cooperation between the tightening band 3 and the wristband body 1 and more effectively preventing the tightening band 3 from detaching from the wristband body 1. Moreover, the provision of a plurality of ribs 14 is also conducive to supporting the shape of the wristband body 1, enabling the wristband body 1 to better fit the wrist.
[0029] In some specific examples, as Figure 1 shown, the rib 14 extends along the width direction of the wristband body 1, and two through holes 141 are provided on the rib 14 at intervals along the width direction of the wristband body 1 for respectively threading the two tightening bands 3. Thus, the rib 14 has better structural strength and a more reliable limiting effect. Moreover, it is also conducive to supporting the shape of the wristband body 1, enabling the wristband body 1 to better fit the wrist.
[0030] For example, the two sides of the width of the wristband body 1 are respectively the first side 12 and the second side 13, the two tightening bands 3 are respectively the first tightening band 31 provided close to the first side 12 and the second tightening band 32 provided close to the second side 13, the rib 14 is a strip-shaped rib extending from the first side 12 to the second side 13, and one through hole 141 is provided at the end of the rib 14 close to the first side 12 for threading the first tightening band 31, and one through hole 141 is also provided at the end of the rib 14 close to the second side 13 for threading the second tightening band 32.
[0031] In some embodiments, as Figure 1 shown, a plurality of ribs 14 are provided on the outer wall of the wristband body 1 at intervals along the length direction of the wristband body 1, and each rib 14 extends along the width direction of the wristband body 1. Two through holes 141 are provided on the rib 14 at intervals along the width direction of the wristband body 1 for respectively threading the two tightening bands 3. Thus, the structure of the wristband body 1 can be simplified, facilitating the processing of the wristband body 1, and the reliability of the cooperation between the tightening band 3 and the wristband body 1 can be improved, effectively preventing the tightening band 3 from detaching from the wristband body 1, and it is also conducive to supporting the shape of the wristband body 1, enabling the wristband body 1 to better fit the wrist.
[0032] In some embodiments of the present application, as Figure 1 shown, a plurality of protrusions 15 are provided on the inner wall of the wristband body 1, and the protrusions 15 are electromyogram detection electrodes. Thus, the wrist device 100 can be an electromyogram detection wristband. By providing electromyogram detection electrodes in the form of protrusions 15, the reliability of the electrode's fit with the wrist can be improved, thereby enhancing the reliability and stability of electromyogram detection.
[0033] Exemplarily, as Figure 1 shown, the wristband body 1 may include an outer wristband 16 and an inner wristband 17, and a circuit component electrically connected to the myoelectric detection electrode is sandwiched between the outer wristband 16 and the inner wristband 17. For example, the circuit component may include a circuit and a chip, etc. Thus, setting the circuit component as a sandwich inside the wristband body 1 can play a role in protecting the circuit component, and there is relatively sufficient space to set the circuit component.
[0034] Exemplarily, as Figure 1 shown, the protrusions 15 may be formed in multiple rows spaced along the width of the wristband body 1, and each row includes a plurality of protrusions 15 spaced along the length direction of the wristband body 1. Thus, the uniform distribution of the protrusions 15 can be easily achieved, improving the effect of myoelectric detection.
[0035] Of course, the present application is not limited thereto. In some other embodiments of the present application, the wrist device 100 may not be a myoelectric detection wristband. For example, it may also be an ordinary wristband without electronic functions, which will not be elaborated here.
[0036] In some embodiments of the present application, as Figure 1 shown, the adjustment component 2 includes a knob 22 and a transmission mechanism 23. The transmission mechanism 23 is connected between the knob 22 and the reel 21 to drive the two reels 21 to rotate synchronously through the rotation of the knob 22. Thus, the user can manually rotate the knob 22 to cause the transmission mechanism 23 to drive the two reels 21 to rotate synchronously, thereby realizing the synchronous shortening or lengthening of the two tightening bands 3. This can simplify the user operation, and the structure of the adjustment component 2 is simple, occupying less space and having a lower cost.
[0037] Among them, the composition of the transmission mechanism 23 is not limited. Exemplarily, as Figure 1 shown, the transmission mechanism 23 may include a worm 231 and a worm wheel 232 that are meshed and transmitted. The knob 22 is connected to the worm 231, and the worm wheel 232 is connected to the two reels 21. In this way, when the knob 22 is rotated, the knob 22 can drive the worm 231 to rotate, the worm 231 drives the worm wheel 232 to rotate, and the worm wheel 232 drives the two reels 21 to rotate synchronously. Thus, the transmission mechanism 23 can effectively transmit the rotation of the knob 22 to the reel 21. Moreover, by switching the rotation direction of the knob 22, the rotation direction of the reel 21 can be changed, thereby switching the shortening and lengthening of the tightening band 3. In addition, the cooperation of the worm 231 and the worm wheel 232 also has a self-locking characteristic. Without applying force to the knob 22, the reel 21 will not be driven to rotate by the tightening band 3, thereby ensuring the stability of the size of the wristband body 1 after adjustment.
[0038] Of course, the present application is not limited to this. In other embodiments of the present application, the two reels 21 may not rotate synchronously. For example, the adjustment assembly 2 may include two knobs 22 and two transmission mechanisms 23. One knob 22 cooperates with one transmission mechanism 23 to drive the rotation of one reel 21, and the other knob 22 cooperates with the other transmission mechanism 23 to drive the rotation of the other reel 21, so that the tightening or loosening of the two tightening bands 3 can be adjusted respectively to better adapt to the thickness of different positions on the wrist.
[0039] Next, with reference to Figure 1 , a wrist device 100 according to a specific embodiment of the present application will be described.
[0040] The wrist device 100 includes a wristband body 1, an adjustment assembly 2, and two tightening bands 3.
[0041] The wristband body 1 includes an inner wristband 17 and an outer wristband 16. A plurality of protrusions 15 are provided on the inner surface of the inner wristband 17, and the protrusions 15 are electrodes for electromyogram detection. A plurality of ribs 14 are provided on the outer surface of the outer wristband 16 at intervals along the length direction of the wristband body 1, and two through holes 141 are provided on each rib 14 at intervals along the width direction of the wristband body 1. The adjustment assembly 2 includes a mounting bracket 24, a knob 22, a worm gear 232, a worm 231, and two reels 21. The mounting bracket 24 is provided on the wristband body 1. The two reels 21 both extend along the width direction of the wristband body 1 and are rotatably supported on both sides of the mounting bracket 24. The worm gear 232 is located inside the mounting bracket 24 and is axially connected to the two reels 21 at both ends. The worm 231 is rotatably supported on the mounting bracket 24, and the knob 22 is provided outside the bracket and connected to the shaft end of the worm 231. The two tightening bands 3 are arranged at intervals along the width direction of the wristband body 1 and surround the wristband body 1. Each tightening band 3 passes through the through holes 141 on the corresponding ribs 14 in sequence, and both ends of the tightening band 3 are fixed to the corresponding reel 21.
[0042] Rotate the knob 22 clockwise to drive the worm 231 to rotate. The worm 231 meshes with the worm gear 232 for transmission, and the worm gear 232 drives the reel 21 to rotate, realizing the shortening of the two tightening bands 3, reducing the opening 11 of the wristband body 1, and the size of the wristband body 1 remains self-locked, and the tightening band 3 will not loosen and lengthen. Rotate the knob 22 counterclockwise to drive the worm 231 to rotate. The worm 231 meshes with the worm gear 232 for transmission, and the worm gear 232 drives the reel 21 to rotate, realizing the lengthening of the two tightening bands 3, increasing the opening 11 of the wristband body 1, and the wrist can be taken out of the wristband body 1. The size of the wristband body 1 remains self-locked, and the tightening band 3 will not shorten. That is to say, whether the knob 22 rotates clockwise or counterclockwise, the tightening band 3 is always in a self-locked state.
[0043] With the continuous development of XR (Extended Reality), the interaction method of the wrist has been paid more and more attention. The myoelectric signal is collected through the channels of each acquisition module, which is usually fixed on the wrist or upper limb. During the fixation process, the magic tape pasting method is usually used for fixation. In some cases, two people need to cooperate to successfully wear it, which causes great inconvenience during use. However, for the wrist device 100 according to this embodiment, under the action of the knob 22, the tightening band 3 can realize the tightening or loosening of the wristband body 1, and keep self-locking at all times during the tightening or loosening process, so that it can be suitable for wrists of different thicknesses to wear, and can realize quick putting on and taking off.
[0044] It can be understood that XR technology refers to combining the real and the virtual through a computer to create a virtual environment for human-computer interaction, which is also a general term for various technologies such as AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality). By integrating the visual interaction technologies of the three, it brings an "immersive feeling" of seamless conversion between the virtual world and the real world to the experiencer.
