[0063] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0064] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0065] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0066] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0067] The present invention provides a belt body.

[0068] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the belt body 200 includes at least two spliced split units 210. At least a first docking portion 300 is provided at the splicing position of one split unit 210, and at least a second docking portion 400 is provided at the splicing position of the other split unit 210. The first docking portion 300 is rotatably arranged relative to the second docking portion 400, and the rotation axis extends along the arrangement direction of the two split units 210. A rotation limiting component is further provided between the first docking portion 300 and the second docking portion 400. When the limiting action of the rotation limiting component is activated, it can limit the rotation of the first docking portion 300 relative to the second docking portion 400.

[0069] In the technical solution of the present invention, when the two split units 210 are spliced, they are docked through the first docking portion 300 and the second docking portion 400. When the rotation limiting component does not exert a limiting effect, the first docking portion 300 rotates relative to the second docking portion 400, and these two split units 210 can also rotate relative to each other. Thus, the included angle between the docked two split units 210 can be changed, and the surface that fits the skin can be flipped. Different sides of the split unit 210 can be configured with different functional components, such as an electrocardiogram sensor, an electromyogram sensor, a heart rate monitoring electrode, a blood pressure monitoring electrode, a motion attitude sensor, a gait analysis electrode, or a display screen, etc. According to different needs, by rotating the two split units 210, different functional components can be made to fit the human skin or be exposed. Or, the relative angle between the side surface of the belt body that fits the skin and the skin can be changed to meet the usage requirements of the functional components provided on this side surface of the belt body 200. When the limiting effect of the rotation limiting component is activated, the angle between the two split units 210 can be maintained unchanged, making the two split units 210 relatively fixed, ensuring the wearing stability of the wearable device, and providing a stable and reliable environment for the use of relevant functional components.

[0070] Without loss of generality, the rotation limiting component can be a cooperative structure of an electromagnet and a magnetic attracting body. By energizing the electromagnet, the electromagnet and the magnetic attracting body cooperate, and the limiting effect of the rotation limiting component can be activated. Of course, it can also be achieved by other structures, such as a structure similar to a rotary switch switching between different gears.

[0071] Further, the second docking portion 400 is movably arranged to have a first position and a second position; at the first position, the second docking portion 400 disengages from the first docking portion 300, and at the second position, the first docking portion and the second docking portion 300 are docked with the first docking portion 200 and can be affected by the rotation limiting component.

[0072] Specifically, when the two split units 210 are docked, it is necessary to first make the second docking portion 400 in the first position so as not to interfere with the first docking portion 300. When the first docking portion 300 is adjusted to a suitable position, then drive the second docking portion 400 to move to the second position, and the second docking portion 400 can be docked with the first docking portion 300. At this time, by the rotation limiting component exerting a limiting effect, the first docking portion 300 and the second docking portion 400 are locked and cooperated, thereby improving the connection stability inside the belt body 200 and ensuring the wearing stability of the wearable device.

[0073] Without loss of generality, the split unit 210 is provided with a docking surface 201 and an installation cavity 202. A first docking portion 300 protrudes from the outer side of the docking surface 201 of one split unit 210, and a through hole 203 communicating with the installation cavity 202 is provided on the docking surface 201 of the other split unit 210. A second docking portion 400 corresponding to the through hole 203 is provided in the installation cavity 202. It can be understood that the first position of the second docking portion 400 is farther from the corresponding through hole 203 than the second position. When the docking surfaces of the two split units 210 are attached, the first docking portion 300 of one split unit 210 can extend into the through hole 203 of the other split unit 210. At this time, when the second docking portion 400 is in the first position, it will not interfere with the extension of the first docking portion 300. After the first docking portion 210 extends in place, the second docking portion 400 is then driven to move from the second position to the first position, thereby completing the docking with the first docking portion 300.

[0074] Among them, the multiple split units 210 may include two first split units respectively connected to both sides of the device main body 100. The shell parts 211 of the two first split units are connected to the device main body 100 on one side, and the docking surface 201 is provided on the other side for connecting with other split units 210. The multiple split units 210 may also include a second split unit with docking surfaces 201 provided on both sides.

[0075] For a belt body 200, two first split units may be provided only. The two first split units are connected through the docking surface 201 at the free ends. Or multiple second split units may be provided, and a wearing ring is formed by enclosing the multiple second split units. The device main body 100 is installed on the outer ring side of the wearing ring. It is also possible to configure a certain number of second split units while providing two first split units. The user can adaptively connect an appropriate number of second split units between the free ends of the two first split units according to the size of the wearing part. Or, different split units 210 may have different appearances and can be matched by the user himself to obtain a belt body 200 with a personalized style. Of course, different split units 210 can also be equipped for the belt body 200 according to other forms.

[0076] It should be noted that the split unit 210 is provided with at least one of a first docking portion 300 and a second docking portion 400. Between the two docking surfaces 201 that are docked, one of them needs to be provided with the first docking portion 300, and the other needs to be provided with the second docking portion 400. That is to say, the split unit 210 of the present invention can be provided with only the first docking portion 300, or can be provided with only the second docking portion 400, or can be provided with both the first docking portion 300 and the second docking portion 400 at the same time. When docking surfaces 201 are provided on opposite sides of the housing 211 of the split unit 210, both docking surfaces 201 can be configured with the first docking portion 300, or both can be configured with the second docking portion 400, or alternatively, one docking surface 201 can be configured with the first docking portion 300 and the other docking surface 201 can be configured with the second docking portion 400.

[0077] In one embodiment, the split unit 210 is configured as a stretchable structure. In this way, after the user wears it, the split unit 210 can adapt to the deformation of the wearing part of the human body, so that each part of the belt body 200 can relatively fit the human body, so as to improve the wearing stability of the wearable device and the wearing comfort of the user. On this basis, each split unit 210 can be configured with the same structure, and the structure of each split unit 210 is not limited to an arc structure, and can also be a straight structure. Depending on the deformation ability of the stretchable structure, a wearing ring can also be formed by enclosing. Of course, in other embodiments, the split unit can also be configured with an appropriate arc structure. Even if the split unit 210 does not have the deformation ability, a suitable wearing ring can also be formed by enclosing.

[0078] Furthermore, an elastic portion is provided on the housing of the split unit 210 so that the split unit 210 can be stretched. Among them, the material of the elastic portion can be a silicone material or a rubber material. Of course, in other embodiments, it can also be to provide a deformable structure that can be retracted and expanded, such as a hinge structure, so that the split unit 210 can adaptively expand different arcs.

[0079] In one embodiment, please refer to Figure 3 and Figure 8, the housing portion 211 has two first side portions 2113 arranged opposite to each other in the penetrating direction of the via hole 203 and a second side portion 2114 connecting the two first side portions 2113, and at least the second side portion 2114 is configured with an elastic material. It can be understood that the splicing surface will be formed on the first side portion 2113, and the second side portion 2114 is configured with an elastic material and is prone to deformation. After the user wears it, the housing portion 211 can fit more closely to the human wearing part to improve the wearing stability of the wearable device. Without loss of generality, the second side portion 2114 can be made of silica gel or rubber material. Further, the electrode 220 can also be configured with an elastic material, so that the electrode 220 can deform with the second side portion 2114. Specifically, the forming slurry of the electrode 220 can have conductivity by incorporating conductive substances into a stretchable non-conductive material. The elasticity of the formed electrode 220 is close to that of the second side portion 2114 to ensure the bonding stability between the electrode 220 and the second side portion 2114.

[0080] Further, the two first side portions 2113 are configured with a hard material, and the second side portion 2114 is configured as an elastic portion. In this way, a certain supporting effect can be provided by the first side portion 2113, and at the same time, the deformation of the second side portion 2114 will not be affected.

[0081] In an embodiment, please refer to Figure 3 , Figure 7 and Figure 8 , the first docking portion 300 is movably arranged and can be switched between a position received in the installation cavity 202 and a position protruding outside the docking surface 201. That is, the first docking portion 300 is telescopically arranged. In this way, when storing, the first docking portion 300 can be retracted to reduce the required storage space. When docking is required, the first docking portion 300 is extended again so that it can penetrate into the corresponding via hole 203 for the corresponding second docking portion 400 to dock. Of course, in other embodiments, the first docking portion 300 can be fixedly arranged at the docking surface 201.

[0082] In an embodiment, each docking surface 201 is provided with the via hole 203, and corresponding to one via hole 203, a first docking portion 300 and a second docking portion 400 are respectively provided. In this way, there is no need to configure an anti-misoperation design at the docking surface 201, and any two docking surfaces 201 can be docked through the first docking portion 300 and the second docking portion 400, which is beneficial to improving the operation convenience of docking.

[0083] It can be understood that the first docking portion 300 will have an avoidance position and an extended position. When the first docking portion 300 is in the avoidance position, the first docking portion 300 can avoid another first docking portion 300 penetrating into the through hole 203 without interfering with the docking of other first docking portions 300 and the second docking portion 400 here; please refer to Figure 7 , when the first docking portion 300 is in the extended position, the first docking portion 300 can penetrate into the through hole 203 of other docking surfaces 201 and dock with the second docking portion 400 therein.

[0084] Furthermore, please refer to Figure 8 , the first docking portion 300 can also have a storage position. When the first docking portion 300 is in the storage position, the end face of the first docking portion 300 is flush with the docking surface 201, so as to block the through hole 203 to a certain extent to prevent excessive dust and other sundries from entering the installation cavity 202, and the first docking portion 300 does not protrude from the docking surface 201, which is convenient for storing the belt body 200. Further, at this position, the second docking portion 400 and the first docking portion 300 corresponding to the same through hole 203 can be docked to ensure that the first docking portion 300 can be stably in the storage position. Of course, in other embodiments, it can also be that a cover is additionally configured, and after the first docking portion 300 retracts to any position, the through hole 203 is blocked by the cover.

[0085] In one embodiment, please refer to Figure 3 , Figure 7 and Figure 8 , a driving device 510 is installed in the belt body 200. The driving device 510 is provided with a driving screw 511, and the driving screw 511 is screwed to the first docking portion 300 to drive the first docking portion 300 to move axially along the through hole 203. In this way, the driving device 510 can drive the driving screw 511 to rotate, thereby driving the first docking portion 300 to move axially. It should be noted that the first docking portion 300 is also slidably connected to a relevant guiding structure, so that when the driving screw 511 rotates, the first docking portion 300 will be restricted by the guiding structure and cannot rotate with the driving screw 511, so as to axially move under the guidance of the guiding structure. Specifically, a chute 205 extending along the axial direction of the through hole 203 can be provided in the installation cavity 202, and a sliding convex portion protrudes from the outer periphery of the first docking portion 300. The sliding convex portion and the chute 205 cooperate to provide a guiding effect for the axial movement of the first docking portion 300. Of course, in other embodiments, it can also be that the first docking portion 300 is driven to move by a linear motor.

[0086] In one embodiment, please refer to Figures 9 to 16, the split unit 210 further includes a rotating part 320. The first docking part 300 includes a main body part 310. The rotating part 320 is rotatably connected to the main body part 310. The second docking part 400 is docked and cooperated with the first docking part 300 by being limitedly fitted to the rotating part 320. The rotation limiting component acts between the rotating part 320 and the main body part 310. It can be understood that after the second docking part 400 and the rotating part 320 are limitedly fitted, the second docking part 400 and the rotating part 320 can remain relatively fixed. When the rotation limiting component plays a limiting role, the rotating part 320 can be fixed relative to the main body part 310, and the second docking part 400 can also be fixed to the main body part 310 to ensure that the wearable device can be worn reliably; when the rotation limiting component does not play a limiting role, the rotating part 320 can rotate relative to the main body part 310, and the second docking part 400 can also rotate relative to the main body part 310, so that relative rotation can also occur between the corresponding two split units 210. Of course, in other embodiments, it may also be that the first docking part 300 and the second docking part 400 are directly limitedly fitted.

[0087] In one embodiment, the rotation limiting component includes a first fitting part provided on the rotating part 320 and a second fitting part provided on the main body part 310. At least one of the first fitting part and the second fitting part is circumferentially and spacedly provided with a plurality of them. Through the corresponding cooperation of at least one of the first fitting part and at least one of the second fitting part, the rotating part 320 and the main body part 310 are in a fixed state. Without loss of generality, the rotating part 320 is annular and is rotatably sleeved on the main body part 310. Taking the first fitting part as an example, when the rotating part 320 and the main body part 310 rotate relative to each other, the first fitting part can be respectively fitted with different second fitting parts, so as to change the relative angle between the two docked split units 210. Of course, in other embodiments, it may also be that the rotating part 320 is integrally configured as an electromagnet, and the circumference of the main body part 310 is provided with a magnetic attraction structure. By switching the on-off of the electromagnet, the rotating part 320 and the main body part 310 are switched between a fixed state and a rotating state. Or, there is a pluggable pin between the main body part 310 and the rotating part 320. When the pin is pulled out, there is a certain gap between the main body part 310 and the rotating part 320, so that the two can rotate relative to each other. When the pin is inserted between the main body part 310 and the rotating part 320, the main body part 310 and the rotating part 320 can be locked, so as to switch the two to a fixed state.

[0088] In one embodiment, the rotating part 320 is provided with two first engaging parts respectively arranged on both sides in the thickness direction of the belt body 200, and / or the main body part 310 is provided with two second engaging parts respectively arranged on both sides in the thickness direction of the belt body 200. That is to say, at least one of the first engaging part and the second engaging part is respectively arranged at the above two positions, and the two engaging parts cooperate by switching positions, so that the two split units 210 to be butted can be flipped by 180 degrees, and the two sides in the thickness direction of the belt body 200 are swapped. That is, the side originally attached to the human skin will be switched to the opposite side. It can be understood that the areas of the two side surfaces of the split unit 210 distributed in the thickness direction are relatively large, and some functional elements can be installed, such as the electrode 220, the display screen 610, etc. By flipping the split unit 210 by 180 degrees, the electrodes 220 with different functions can be attached to the human skin, or the display screen 610 can be exposed on the outside when needed.

[0089] In one embodiment, please refer to Figures 9 to 12 , the first engaging part is configured as a first electromagnet 701, the second engaging part is configured as a magnetic attracting part 321. When the first electromagnet 701 is energized, the first electromagnet 701 and the opposite magnetic attracting part 321 are magnetically attracted, so that the limiting function of the rotation limiting component is activated.

[0090] It can be understood that the first electromagnet 701 has magnetism when it is energized, and the magnetic attracting part 321 can be magnetically attracted by the first electromagnet 701, so that the rotating part 320 and the main body part 310 can be fixed. Therefore, during the user's wearing process, the first electromagnet 701 can be energized to make the rotating part 320 in a fixed state and not rotate easily, so as to ensure the wearing stability of the wearable device.

[0091] After the first electromagnet 701 is powered off, it will lose its magnetism, and there is no attractive force between the magnetic attracting part 321 and the first electromagnet 701. The rotating part 320 can rotate relatively freely relative to the main body part 310 to adjust the relative angle of the two butted split units 210. The arrangement positions of multiple magnetic attracting parts 321 can be designed as needed. When the rotating part 320 rotates to each target position, there can be a magnetic attracting part 321 opposite to the first electromagnet 701. At this time, by energizing the first electromagnet 701 again, the rotating part 320 can be stably in the current position to ensure the wearing stability of the wearable device in different states.

[0092] It should be noted that the magnetic attracting part 321 should be a ferromagnetic material such as iron, cobalt, and nickel, so that it can be magnetically attracted to the first electromagnet 701 after the first electromagnet 701 is energized, and it will not generate magnetic attraction to the first electromagnet 701 after the first electromagnet 701 is powered off.

[0093] Of course, in other embodiments, it is also possible that one of the main body portion 310 and the rotating portion 320 is provided with a clamping protrusion, and the other is provided with an annular groove. The annular groove has a plurality of engaging positions spaced circumferentially, and the space between two adjacent engaging positions is a free position. The groove width at the engaging position is greater than the notch at the free position. The clamping protrusion and the engaging position are respectively the first mating portion and the second mating portion.

[0094] In one embodiment, please refer to Figure 3 , a circuit board 600 is further installed in the installation cavity 202. The first electromagnet 701 is electrically connected to the circuit board 600 through a first electrical connector 700. The first electrical connector 700 passes through the main body portion 310. In this way, the on / off of the first electromagnet 701 can be controlled by the circuit board 600 in the installation cavity 202. The first electrical connector 700 passes through the main body portion 310, and there is no need to additionally design the wiring structure of the first electrical connector 700, which is beneficial to simplifying the structure in the installation cavity 202. Among them, the circuit board 600 can be connected to the main control board of the device main body 100 by wireless connection or wired connection. Of course, in other embodiments, the first electromagnet 701 can also be electrically connected to the main control board of the device main body 100.

[0095] In one embodiment, please refer to Figures 3 to 6 and Figures 9 to 16 , an installation cylinder 520 is fixedly arranged in the installation cavity 202. One end of the installation cylinder 520 is provided with an installation opening 521, and the inner end face of the other end protrudes with a positioning shaft 522. The main body portion 310 is inserted into the installation cylinder 520, the positioning shaft 522 is inserted into one end of the main body portion 310, and the rotating portion 320 is arranged at the other end of the main body portion 310;

[0096] The first electrical connector 700 includes a first connection section 710, a second connection section 720, and a winding section 730 arranged between the first connection section 710 and the second connection section 720. The first connection section 710 passes through the main body portion 310 and is connected to the first electromagnet 701. The second connection section 720 passes through the installation cylinder 520 and is connected to the circuit board 600 and is bent. The winding section 730 is wound around the positioning shaft 522 in the direction from inside to outside and is located between the opposite end faces of the main body portion 310 and the installation cylinder 520.

[0097] It can be understood that the installation cylinder 520 can provide a stable installation environment and a certain guiding function for the first docking part 300. Further, a guiding structure for restricting the rotation of the main body part 310 and guiding the axial movement of the main body part 310 can be arranged inside the installation cylinder 520. For example, the positioning shaft 522 can be eccentrically arranged, and a straight groove adapted to the positioning shaft 522 is arranged on the main body part 310. Through the cooperation of the positioning shaft 522 and the straight groove, the axial movement of the first docking part 300 is guided. Of course, it can also be that a convex part protrudes from the outer peripheral side of the main body part 310, and a groove track is arranged on the inner peripheral side of the positioning cylinder. Through the sliding cooperation of the convex part and the groove track, the axial movement of the first docking part 300 is guided.

[0098] In this embodiment, the second connection section 720 is bent, and the winding section 730 is wound around the positioning shaft 522. When the first docking part 300 moves, both the second connection section 720 and the winding part can provide a certain amount of telescopic margin, avoiding breakage of the first electrical connector 700, so as to ensure the stable connection between both ends of the first electrical connector 700 and the corresponding structure.

[0099] Among them, since the winding section 730 is spirally arranged from the inside to the outside in the form of a rolled material, each layer of the winding section 730 overlaps, and the friction between adjacent layers is large and it is not easily stretched. The second connection section 720 is relatively easier to deform. Therefore, the smoothness of the outer surface of the positioning shaft 522 can be improved, so that the winding section 730 can easily slide on the positioning shaft 522. In this way, when the first docking part 300 moves, the telescopic margin is mainly provided by the second connection section 720. It can be understood that the bent setting of the second connection section 720 enables it to be gradually straightened, while the winding section 730 moves along with the first docking part 300, so as to avoid the first connection section 710 from being pulled, enabling the first connection section 710 to be relatively neatly arranged on the first docking part 300 to avoid interfering with the movement of the first docking part 300.

[0100] Further, the axial width of the winding section 730 is relatively large, much larger than the line widths of the two connection sections. In this way, after the winding section 730 is stretched, the edges of each winding layer can maintain an overlapping state. When the first docking part 300 retracts, the winding section 730 will not be misaligned and can easily return to the initial winding state.

[0101] Without loss of generality, the first electrical connector 700 is configured with a flexible material to ensure that the first electrical connector 700 has sufficient deformation ability, facilitating the installation of the first electrical connector 700, ensuring the telescopic margin of the first electrical connector 700, thereby ensuring the structural stability of the first electrical connector 700 and the electrical connection stability between the electrical components on the first docking part 300 and the circuit board 600.

[0102] Without loss of generality, the first electrical connector 700 is integrally formed to ensure the structural stability of the first electrical connector 700. When installing the first electrical connector 700, the second connecting section 720 can be passed through the through hole 203 on the main body 310, and then the winding section 730 is pulled through the through hole 203 by the second connecting section 720. At the same time, a part of the first connecting section 710 will also penetrate into the through hole 203. Then, the winding section 730 is wound around the positioning shaft 522, and the second connecting section 720 is connected to the circuit board 600.

[0103] In one embodiment, please refer to Figures 9 to 16 , the first docking part 300 further includes an end cap 330. The end of the main body 310 is provided with a first boss 311. The first electromagnet 701 is exposed on the outer peripheral side of the first boss 311. The end cap 330 is fixedly connected to the first boss 311 and forms a limiting ring groove 301 with the main body 310. The rotating part 320 is rotatably installed in the limiting ring groove 301. The limiting ring groove 301 can play a good role in axially limiting the rotating part 320. After the magnetic attracting part 321 on the rotating part 320 is magnetically attracted by the first electromagnet 701, the rotating part 320 and the main body 310 can be well maintained in a relatively fixed state. When the rotating part 320 is in limiting cooperation with the second docking part 400 corresponding to the other docking surface 201, the docking stability between the two docking surfaces 201 can be ensured. On this basis, after the first electromagnet 701 exposed on the outer peripheral side of the first boss 311 is aligned with the magnetic attracting part 321, the distance between the two is relatively short, which can ensure that there is sufficient magnetic attraction between the two. In addition, the limiting ring groove 301 is jointly formed by the stepped structure formed at the first boss 311 and the end cap 330, which is convenient for the installation of the rotating part 320. After the rotating part 320 is sleeved on the first boss 311, the end cap 330 and the first boss 311 can be connected.

[0104] In one embodiment, please refer to Figures 9 to 16, the first docking part 300 is also provided with a sensor 702, the sensor 702 is used to sense the position of the first docking part 300, the first electrical connector 700 is also electrically connected to the sensor 702, and the sensor 702 is exposed on the end cover 330. Specifically, when the first docking part 300 penetrates to a certain position in the through hole 203, the sensor 702 can obtain relevant feedback. After the control module obtains the feedback, it can determine that the first docking part 300 is inserted into the position, so that the first docking part 300 can be controlled to stop moving, and the second docking part 400 can be triggered to move toward the second position to dock with the first docking part 300. Without loss of generality, the sensor 702 can be a photoelectric sensor. When the first docking part 300 is inserted into the through hole 203 of another docking surface 201, the distance between the two can be obtained through the light reflected by the structure opposite to the first docking part 300 (such as another first docking part 300). When the distance between the two reaches a certain value, it means that the first docking part 300 is inserted into the position. The sensor 702 may be an infrared detector or a laser sensor. Of course, in other embodiments, the sensor 702 may also be a piezoelectric sensor. After the position where the piezoelectric sensor is arranged on the first docking portion 300 abuts against the corresponding structure, the first docking portion 300 moves into place, and at this time, the piezoelectric sensor can obtain a corresponding sensing signal.

[0105] In one embodiment, please refer to Figures 9 to 12 The end surface of the first boss 311 is provided with a mounting groove 312, and the outer peripheral side of the first boss 311 is provided with a first opening 313 connected to the mounting groove 312. The first electrical connector 700 includes an arc portion 711 and a penetration portion 712 and a transition portion 713 connected to the middle section of the arc portion 711. The arc portion 711 is installed in the mounting groove 312. The first electromagnet 701 is arranged at the end of the arc portion 711 and is exposed through the first opening 313. The penetration portion 712 is axially penetrated in the main body 310. The transition portion 713 overlaps the end surface of the first boss 311. The sensor 702 is arranged on the transition portion 713. The end cover 330 is provided with a second opening 331, and the sensor 702 is exposed through the second opening 331.

[0106] It can be understood that the mounting groove 312 should be arc-shaped, and the arc-shaped portion 711 should be adapted to be installed in the mounting groove 312, so as to provide good protection for the arc-shaped portion 711 to ensure the combination stability between the first electromagnet 701 and the arc-shaped portion 711. On this basis, the setting of the first opening 313 can make the first electromagnet 701 exposed to the outside to ensure the combination stability between the first electromagnet 701 and the magnetic attraction portion 321.

[0107] The adapter 713 is sandwiched between the end cover 330 and the first boss 311, which can play a strong limiting role on the adapter 713, and the sensor 702 can be stably located in the detection position. Further, the sensor 702 can be protruded on the side of the adapter 713 away from the first boss 311, and inserted into the second opening 331 to ensure the installation stability of the sensor 702.

[0108] In addition, the structure of the first electrical connector 700 can facilitate the layout of other related structures and achieve cooperation with the first docking portion 300, which will be elaborated in detail later.

[0109] In one embodiment, see Figure 3 , Figure 7 and Figure 8 , the second docking portion 400 includes two clamping portions 410. In the first position, the two clamping portions 410 are distributed on both radial sides of the through hole 203 and can move toward each other to the second position. Specifically, when the second docking portion 400 is in the first position, the two clamping portions 410 are relatively far away from the through hole 203, that is, they will not block the first docking portion 300 from penetrating from the through hole 203. When the first docking portion 300 penetrates to a suitable position, the clamping portions 410 move toward each other. It can be understood that there is an angle between the movement direction of the clamping portions 410 and the penetration direction of the first docking portion 300. Therefore, the position of the first docking portion 300 will not interfere with the movement of the clamping portions 410. When the clamping portions 410 move to the second position, they can be clamped with the first docking portion 300, thereby achieving docking with the first docking portion 300, so that the first docking portion 300 cannot be pulled out from the through hole 203 into which it penetrates. Of course, in other embodiments, the second docking portion 400 may also be configured as a pin, and the first docking portion 300 is correspondingly configured with a hole extending in the radial direction, and the docking with the first docking portion 300 is achieved by inserting the pin into the hole.

[0110] In one embodiment, see Figure 3 , Figure 7 and Figure 8 Two first magnet parts 204 are provided in the installation cavity 202, and the two first magnet parts 204 are respectively distributed on the opposite sides of the two clamping parts 410, and a second magnet part 411 is correspondingly provided on the opposite sides of the two clamping parts 410, and at least one of the first magnet part 204 and the second magnet part 411 is configured as an electromagnet, and at most one is configured as a permanent magnet.

[0111] Among them, one of the first magnet part 204 and the second magnet part 411 can be configured as an electromagnet, and the other can be configured as a permanent magnet, or both can be configured as electromagnets. Since the electromagnet needs to be powered on and considering that the clamping part 410 needs to move, it is advisable to configure the first magnet part 204 as a permanent magnet and the second magnet part 411 as an electromagnet. It can be understood that the electromagnet should be electrically connected to the circuit board 600.

[0112] In this way, by changing the current direction of the second magnet part 411, the pole direction of the second magnet part 411 can be changed to switch the interaction force between the first magnet part 204 and the second magnet part 411, thereby changing the position of the clamping part 410. When there is a magnetic attraction force between the first magnet part 204 and the second magnet part 411, the clamping part 410 at the second position will be attracted to the first position, that is, the two clamping parts 410 move away from each other, so that the second docking part 400 can be switched from the second position to the first position, and under the action of the magnetic attraction force, the two clamping parts 410 can also be stably in the first position; when there is a magnetic repulsion force between the first magnet part 204 and the second magnet part 411, the clamping part 410 at the first position will be repelled to the second position, that is, the two clamping parts 410 will move towards each other, and under the action of the magnetic repulsion force, the two clamping parts 410 can also be stably in the second position.

[0113] Of course, in other embodiments, the clamping part 410 can also be driven to move by a motor. A rack structure can be provided on each of the two clamping parts 410. The two rack structures extend towards each other and are distributed on the radial sides of a gear. By driving the gear to rotate by a motor, the two clamping parts 410 can be driven to move towards each other or away from each other by one motor at the same time. Or, the two clamping parts 410 can also be driven by two motors respectively.

[0114] In one embodiment, please refer to Figure 3 、 Figure 7 and Figure 8 A chute 205 is formed in the installation cavity 202. A roller 412 is provided on the side of the clamping part 410 and is in rolling cooperation with the chute 205 through the roller 412. In this way, the chute 205 can provide a guiding effect for the movement of the clamping part 410, and the cooperation between the roller 412 and the chute 205 is beneficial to reducing the friction force received when the clamping part 410 moves, thereby ensuring the smooth movement of the clamping part 410. Of course, in other embodiments, corresponding structures such as balls and rollers can also be provided in the chute 205, and the sliding friction can also be changed into rolling friction.

[0115] In one embodiment, please refer to Figure 3 and Figure 4, a limiting ring groove 301 capable of allowing the clamping portion 410 to be inserted therein is formed in the first docking portion 300. It can be understood that after the clamping portion 410 is inserted into the limiting ring groove 301, the first docking portion 300 can be axially limited, thereby realizing the docking between the second docking portion 400 and the first docking portion 300, so as to prevent the first docking portion 300 from disengaging from the penetrated through hole 203, and ensure the connection stability between different docking surfaces 201. Specifically, the limiting ring groove 301 is formed by the cooperation of the stepped structure formed by the aforementioned main body portion 310 at the first boss 311 and the end cover 330. Of course, in other embodiments, it may also be that a clamping protrusion is formed on the outer peripheral surface of the first docking portion 300, and a clamping groove is correspondingly provided on the clamping portion 410, and the docking between the second docking portion 400 and the first docking portion 300 is realized by inserting the clamping protrusion into the clamping groove.

[0116] In one embodiment, please refer to Figure 3 , Figure 4 and Figures 9 to 12 as well, a rotatable rotating portion 320 is installed in the limiting ring groove 301. The rotating portion 320 includes two ring portions 322 spaced apart along the axial direction. The two ring portions 322 are connected by a plurality of magnetic attraction portions 321 distributed along the circumferential direction. The clamping portion 410 is clamped between the two ring portions 322 and is located between two adjacent magnetic attraction portions 321. In this way, both sides of the clamping portion 410 will be limited by the two ring portions 322 respectively, so that the axial displacement of the rotating portion 320 is limited by the clamping portion 410. The clamping portion 410 is clamped between two adjacent magnetic attraction portions 321, which can limit the circumferential rotation of the rotating portion 320 by the clamping portion 410. Thus, the rotating portion 320 can be comprehensively limited by the clamping portion 410. When the rotating portion 320 is in a fixed state, the first docking portion 300 as a whole can also be limited by the clamping portion 410, thereby realizing the docking between the second docking portion 400 and the first docking portion 300. Among them, annular grooves can be respectively provided on the opposite end faces of the main body portion 310 and the end cover 330 for accommodating the two ring portions 322.

[0117] Specifically, two magnetic attraction portions 321 are provided on the rotating portion 320. The first docking portion 300 axially moves along the length direction of the belt body 200, and the two clamping portions 410 are distributed along the width direction of the belt body 200. When the rotating portion 320 is in a fixed state, the two magnetic attraction portions 321 are arranged opposite to each other in the thickness direction of the belt body 200. In this way, when the clamping portion 410 is clamped with the rotating portion 320, it will not be interfered by the magnetic attraction portions 321.

[0118] Correspondingly, the installation position of the first electromagnet 701 is set close to one of the two side surfaces of the belt body 200 distributed in the thickness direction, and the circuit board 600 is also attached to one of the two side surfaces. The first electromagnet 701 and the circuit board 600 can be set corresponding to the same side surface, or can be set corresponding to the two side surfaces respectively. Further, the first electromagnet 701 is arranged at the end of the arc-shaped portion 711 of the first electrical connector 700, and the penetrating portion 712 is connected to the middle section of the arc-shaped portion 711. In this way, the penetrating portion 712 penetrates through the side of the main body portion 310 at a relatively central position in the thickness direction of the belt body 200, and the leading-out position of the second connection section 720 can also be located at a relatively central position. In this way, it will neither be too close to the circuit board 600 nor too far from the circuit board 600.

[0119] It can be understood that if the leading-out position of the second connection section 720 is too close to the circuit board 600, on the premise that the second connection section 720 needs to reserve sufficient telescopic margin, it may cause the second connection section 720 to droop, thus hanging on the circuit board 600 or other structures, resulting in the disconnection of the second connection section 720 and the circuit board 600, or even damaging the structure of the first electrical connector 700; when the leading-out position of the second connection section 720 is too far from the circuit board 600, the length of the second connection section 720 will be increased, thus increasing the corresponding cost.

[0120] In this embodiment, by setting the arc-shaped portion 711 and reasonably distributing the installation position of the first electromagnet 701 and the connection position of the penetrating portion 712, the penetrating portion 712 can penetrate through the main body portion 310 along the axis. When drilling holes in the main body portion 310, the operation is relatively convenient, and the leading-out position of the second connection section 720 is also relatively appropriate. While ensuring sufficient telescopic margin, it can stably realize the electrical connection between the first electrical connector 700 and the circuit board 600, and at the same time, it can also have a suitable production cost.

[0121] In one embodiment, please refer to Figure 17 and Figure 18, an electrode 220 is convexly provided on the outer surface of the housing portion 211 of the split unit 210 adjacent to the via hole 203, and the electrode 220 is formed on the housing portion 211 at least by a molding electrode 220 forming process. Specifically, the mold 900 is placed below the housing portion 211, and there is a gap between the outer surface of the housing portion 211 and the mold 900. The housing portion 211 is correspondingly provided with a material injection hole. After the paste is injected from this material injection hole, it can flow to the gap between the housing portion 211 and the mold 900, and then an electrode 220 convexly provided on the outer surface of the housing portion 211 can be formed. In this embodiment, the electrode 220 is convexly provided on the outer surface of the housing portion 211 and is adjacent to the via hole 203, so that the electrode 220 can contact the human skin to obtain relevant parameters of the user. The electrode 220 can be used for electrocardiogram monitoring, electromyogram monitoring, skin conductance response monitoring, bioimpedance analysis, motion tracking, and posture recognition, etc.

[0122] Among them, electrocardiogram monitoring specifically measures the weak electrical signals generated by the heart through the electrode 220 in contact with the skin, so as to generate an electrocardiogram; electromyogram monitoring specifically records the electrical signals generated during muscle activity, and is used to evaluate the functional state of the muscles or control external devices (such as prosthetics or character movements in games); skin conductance response monitoring is also called skin electrical activity. This technology measures the changes in skin conductivity, which is usually associated with emotional changes, stress levels, and autonomic nervous system activities; bioimpedance analysis specifically estimates physiological parameters such as body fat percentage, water content, and muscle mass by applying a small current to the body and measuring its resistance. In addition, the electrode 220 can also help identify the user's movement type and posture to improve the accuracy of motion tracking.

[0123] In one embodiment, please refer to Figure 17 and Figure 18 , the electrode 220 includes an electrode body 221 and a conductive layer 222 which are stacked. The electrode body 221 is exposed on the outer surface of the housing portion 211 and is formed on the housing portion 211 by a molding electrode 220 forming process. The conductive layer 222 is exposed on the inner surface of the housing portion 211 and is electrically connected to the circuit board 600 in the installation cavity 202 through a second electrical connector 800. In this embodiment, the electrode body 221 is formed by an electrode 220 paste, and the conductive layer 222 is formed by a circuit paste. Their components are different and the effects are also different. In this embodiment, by differentiating the design of different layers of the electrode 220, the electrode body 221 can better detect the human body, and the conductive layer 222 can better realize the electrical connection between the electrode 220 and other structures. Of course, in other embodiments, the electrode 220 can also be injection-molded with a paste of the same composition.

[0124] Without loss of generality, the inner side surface of the shell 211 is formed with a groove surrounding the injection hole. When the electrode 220 is formed, a certain amount of electrode 220 slurry is first injected into the injection hole. The material of the electrode 220 slurry needs to exceed the injection hole and enter the groove. The electrode body 221 formed in this way has a roughly I-shaped cross-section, and both ends can be limited by the injection hole, which is beneficial to ensure the bonding strength between the electrode body 221 and the shell 211. Furthermore, a plurality of injection holes can be provided, which can further enhance the bonding strength between the electrode body 221 and the shell 211.

[0125] After the electrode body 221 is formed, a certain amount of circuit slurry is injected into the groove to form a conductive layer 222. The conductive layer 222 can be flush with the inner side of the shell 211. The conductive layer 222 is then connected to the circuit board 600 through the second electrical connector 800, so that the human body signal obtained by the electrode 220 can be transmitted to the relevant control module.

[0126] Furthermore, the outer surface of the shell 211 is convexly provided with a second boss 2112, the second boss 2112 is configured with an elastic material, and the electrode body 221 is formed on the second boss 2112. In this way, through the protruding setting of the second boss 2112, the electrode body 221 can protrude a sufficient height from the outer side of the shell 211 to ensure that the electrode 220 can be in close contact with the human skin, so as to effectively detect relevant parameters. In addition, the second boss 2112 is elastic and will not cause excessive pressure on the human body, which is conducive to ensuring the comfort of the user.

[0127] In one embodiment, see Figure 17 and Figure 18 A display screen 610 is installed on the side of the circuit board 600 away from the electrode 220, and a clearance opening 2111 is provided on the shell 211, through which the display screen 610 is exposed. In this way, when the user performs health monitoring, relevant information such as electrocardiogram, blood oxygen concentration, etc. can be displayed on the display screen 610, so that the user can observe the detection data more intuitively without occupying the screen of the device body 100.

[0128] Furthermore, the second electrical connector 800 is made of a flexible material. When the second side portion 2114 is deformed, the second connector can be stretched or contracted to a certain extent without damaging the structure of the second connector itself or the connection between the second connector and the electrode 220 and the circuit board 600.
