DETAILED DESCRIPTION
[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

Figure 8 Shows Figure 7 For the convenience of description, only the parts related to the utility model are shown in the figure.
[0036] It should be noted that the directional indications involved in the present invention (such as up, down, front, back, etc.) are only used to explain the relative position relationship between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly; in addition, the descriptions of "first", "second", etc. involved in the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
[0037] Depend on Figures 1 to 8It can be seen that the wristband of the utility model is applied to wearable devices, and the side of the wristband close to the user's wrist 90 is defined as the inner side, and the other side away from the user's wrist 90 is defined as the outer side; the wristband includes an elastic belt body 10, an electrical connection terminal 40 arranged at the end of the elastic belt body 10 close to the host 80 of the wearable device, and at least one electrode 20 arranged on the inner side of the elastic belt body 10, and an elastic circuit 30 is respectively connected between each electrode 20 and the electrical connection terminal 40, and the elastic circuit 30 is made of elastic conductive material and embedded in the elastic belt body 10; usually, there are multiple electrodes 20, and there are multiple elastic circuits 30 correspondingly, for example, seven electrodes 20 and seven elastic circuits 30 corresponding to the electrodes 20 one by one, and the specific number is determined according to actual needs.
[0038] When the wearable device is worn, the wristband is wrapped around the user's wrist 90, and at least one electrode 20 arranged on the inner side of the elastic belt body 10 is in contact with the skin of the wrist 90, which can realize functions such as body fat detection, electrocardiogram detection, body temperature detection, and blood oxygen detection. The space inside the elastic belt body 10 is large, and more electrodes 20 can be set, and there is no need to set electrodes 20 on the back of the host 80; at the same time, the wristband will be stretched during the process of wearing the wearable device on the user's wrist 90 and when the user's wrist 90 moves after wearing. Since the elastic belt body 10 is elastic and can be stretched, the elastic circuit 30 is made of elastic conductive material and embedded in the elastic belt body 10. When the wristband is stretched, the elastic circuit 30 can be stretched synchronously, which can avoid damage to the elastic circuit 30, so that the wristband maintains the detection function. At least one electrode 20 that realizes the detection function is set on the inner side of the elastic belt body 10 of the wristband. The wristband of the utility model solves the problem of inconvenience in setting electrodes on the back of the host of the wearable device, and more electrodes can be set on the wristband to meet the use requirements.
[0039] In the present invention, in order to prevent the electrode 20 from moving relative to the wrist 90 or separating from the wrist 90 due to drift between the wristband and the user's wrist 90 when the wearable device is worn, thereby causing the electrode 20 to obtain unstable signals, an anti-slip structure 13 is provided on the inner side of the elastic band 10.
[0040] like Figure 3 As shown, the anti-slip structure 13 is a bristle structure, which includes a plurality of long strips of bristles 131 arranged side by side along the length direction of the elastic belt body 10, and the cross-section of the bristles 131 is arranged in a triangular shape, and the first side surface close to the electrical connection terminal 40 and the second side surface away from the electrical connection terminal 40 are both inclined in the direction away from the electrical connection terminal 40.
[0041] Specifically, in a natural state, the height of the bristles 131 from the inner side of the elastic belt body 10 is h, 80um≤h≤120um; the width of the side of the bristles 131 that is in contact with the inner side of the elastic belt body 10 in the length direction of the elastic belt body 10 is w, 40um≤w≤80um; the angle between the second side surface of the bristles 131 and the inner side of the elastic belt body 10 is α, 45°≤α≤60°. After wearing the wearable device, the wristband is attached to the wrist 90, and the multiple bristles 131 are squeezed, resulting in elastic deformation, such as Figure 7 As shown, the contact area is increased, and van der Waals force is generated between the wristband and the wrist 90, so that the wristband and the wrist 90 can fit tightly together to avoid drift between the wristband and the wrist 90. The van der Waals force is an intermolecular force, and the van der Waals force can only be generated when the contact area is large enough and the contact feature (bristle 131) is small enough.
[0042] As a preferred implementation, w=60um, h=100um, and angle α=53°.
[0043] In some other embodiments, the anti-slip structure 13 may also be configured as the following structure, including a plurality of spherical protrusions, and the plurality of spherical protrusions are arranged vertically and horizontally along the length direction and the width direction of the elastic belt body 10 .
[0044] Typically, the anti-skid structure 13 is disposed on a side of the elastic belt 10 away from the electrical connection terminal 40 , and the anti-skid structure 13 is connected to the elastic belt 10 as an integral structure, such as injection molding, which is easy to process.
[0045] In the present invention, in order to prevent the elastic circuit 30 from affecting the detection of the electrode 20 , a circuit shielding system is provided on the elastic belt 10 .

The outer shielding layer 63 is arranged as an annular structure adapted to the inner shielding layer 53. The outer shielding layer 63 is attached to and connected with the inner shielding layer 51, and also includes an outer cover plate 62 covered on the outer shielding layer 61; a side of the inner shielding layer 53 away from the inner shielding layer 51 is attached to a side of the outer shielding layer 63 away from the outer shielding layer 61, and a closed shielding space is formed among the inner shielding layer 51, the inner shielding layer 53, the outer shielding layer 63 and the outer shielding layer 61, and a avoidance portion 532 for the elastic circuit 30 to pass through is provided on a side of the closed shielding space close to the electrical connection terminal 40.
[0048] like Figure 6 As shown, the inner shielding layer 53 includes a plurality of inner shielding strips 531, which are arranged in sequence along the length direction and the width direction of the inner belt body 11 to form a rectangular inner shielding frame, and a avoidance portion 532 is formed between adjacent inner shielding strips 531 on the side close to the electrical connection terminal 40. Correspondingly, the outer shielding layer 63 includes a plurality of outer shielding strips, which are arranged in sequence along the length direction and the width direction of the outer belt body 12 to form an outer shielding frame that matches the shape of the inner shielding frame. Since the plurality of inner shielding strips 531 of the inner shielding layer 53 are arranged in sequence along the length direction and the width direction of the inner belt body 11, and the plurality of outer shielding strips of the outer shielding layer 63 are arranged in sequence along the length direction and the width direction of the outer belt body 12, it is convenient to fix the inner shielding layer 53 and the inner belt body 11, and the outer shielding layer 63 and the outer belt body 12 together.
[0049] In order to facilitate processing and installation, a circuit groove matching the shape of the elastic circuit 30 is provided on the side of the inner belt body 11 close to the outer belt body 12, and a mounting hole connected to the circuit groove is provided on the groove bottom surface at the end of the circuit groove away from the electrical connection terminal 40, for installing the electrode 20. During processing, the inner belt body 11 is placed in the positioning groove of the inner belt body fixture, and an electrode groove is provided at the groove bottom surface of the positioning groove corresponding to the mounting hole, and then the liquid elastic conductive material is introduced into the circuit groove of the inner belt body 11. At the same time, part of the liquid can flow into the electrode groove through the mounting hole. After the circuit groove and the electrode groove are filled with liquid elastic conductive material, they are baked at high temperature for curing, and the elastic circuit 30 can be formed in the circuit groove, and the electrode 20 can be formed in the electrode groove. The elastic circuit 30 is tightly connected with the electrode 20 and the inner belt body 11. Commonly used elastic conductive materials include composite materials composed of conductive hydrogel, conductive rubber, conductive agent and elastomer substrate.
[0050] Furthermore, an inner elongated hole is provided on the inner belt body 11 corresponding to each inner shielding strip 531. When the liquid elastic conductive material is introduced into the circuit groove, the liquid elastic conductive material is introduced into each inner elongated hole respectively. When the elastic circuit 30 is formed, an inner shielding strip 531 can be formed in each inner elongated hole. There is no need for separate installation, which can improve production efficiency. In order to facilitate the connection between the inner shielding layer 53 and the inner shielding layer 51, the inner shielding layer 51 is arranged inside the accommodating groove on the inner cover plate 52. For example, the inner shielding layer 51 is directly formed inside the accommodating groove on the inner cover plate 52 by spraying. Of course, the pre-processed inner shielding layer 51 can also be fixed inside the accommodating groove on the inner cover plate 52 by bonding, hot pressing, etc., and then the inner cover plate 52 and the inner belt body 11 are fixed together, and then the fixed inner belt body 11 and the inner cover plate 52 are placed in the positioning groove of the inner belt body fixture, and then the liquid elastic conductive material is introduced into the circuit groove, the electrode groove and the inner elongated hole respectively. When cured by high-temperature baking, the inner shielding strip 531 formed inside the inner elongated hole is fixedly connected to the inner shielding layer 51.
[0051] Correspondingly, an outer elongated hole is provided on the outer belt body 12 corresponding to each outer shielding strip; the way the outer shielding strip is formed inside each outer elongated hole is the same as the way the inner shielding strip 531 is formed, the way the outer shielding layer 61 is formed is the same as the way the inner shielding layer 51 is formed, and the way the outer shielding strip and the outer shielding layer 61 are fixedly connected is the same as the way the inner shielding strip 531 and the inner shielding layer 51 are fixedly connected.
[0052] Of course, in some other embodiments, the elastic circuit 30 may be pre-formed, and then the electrode 20 may be installed on the formed elastic circuit 30, and the elastic circuit 30 may be fixed inside the circuit groove of the inner belt body 11 by bonding, hot pressing, etc.
