[0002] Smart terminal devices worn on the body can monitor the body through various sensors. For example, it can monitor heart rate, heart rhythm, motion, exercise, and sleep. When measuring various body signs, the sensor needs to be relatively fixed with the body. If the sensor moves relative to the body, it may have a certain impact on the measurement data.

[0003] Taking smart watches and bracelets as an example, if the sensor cannot always be in close contact with the user's body during movement, the final measurement data will have certain errors. Even if the sensor is always in close contact with the user's body, if the sensor slides along the surface of the user's body, it will affect the accuracy of the measurement data to a certain extent. In particular, some current smart watch products mostly set the host device with various sensors integrated in the strap. However, since the host device is usually large, when the user actually wears it, even if the strap is tightened, it is still easy for the host device to slide against the body.

[0013] As an implementation manner, the connecting frame is a U-shaped frame or a rectangular frame.

[0014] As an embodiment, second connecting rings for the belt body to pass through are formed at both ends of the connecting frame, and a second hole opposite to the first hole is also formed on the connecting frame; wherein the protrusion is arranged in the first hole and the second hole.

[0015] As an embodiment, the limiting portion is a third card slot relatively arranged on the inner side of the connecting frame, and a third card block is formed on the side of the host and is engaged with the third card slot; or the limiting portion is a third card block relatively arranged on the inner side of the connecting frame, and a third card slot is formed on the side of the host and is engaged with the third card block.

[0016] As an implementation manner, the connecting frame is a U-shaped frame or a rectangular frame.

[0017] As an embodiment, a magnet capable of being attracted to the host is disposed on the periphery of the first hole; or a magnet capable of being attracted to the belt is disposed in the host.

[0056] Embodiment 1

[0057] like Figures 1a to 4bAs shown, in this embodiment, a terminal device is disclosed, which includes a belt body 1, a host 2 and a connecting frame 3. A first hole 41 is provided on the belt body 1. The host 2 is arranged on the inner side of the belt body 1, and a protrusion 21 opposite to the first hole 41 is provided on one surface of the host 2, and a sensor 22 is provided on another surface and / or inside for measuring various body signs. The connecting frame 3 is also connected to the inner side of the belt body 1, and its left end is connected to the first end of the belt body 1, and a limiting portion 31 for accommodating the host 2 is formed on the connecting frame 3.

[0058] In this embodiment, the terminal device is used as a wristband to illustrate its usage. Specifically, when wearing the terminal device, the host 2 is set in the limiting portion 31 in the connecting frame 3, and then the connecting frame 3 is connected to the inner side of the belt body 1, and the protrusion 21 on the host 2 is placed in the first hole 41 from the inner side of the belt body 1, and finally the belt body 1 is worn on the user's body. After the protrusion 21 is set in the first hole 41, the belt body 1 can form a radial position restriction on the host 2 along the first hole 41, and the connection between the connecting frame 3 and the belt body 1 can further increase the stability of the host 2. The superposition of the force applied by the belt body 1 to the host 2 toward the center of the body can make the host 2 fit more firmly on the body, ensuring that the sensor 22 therein will not move significantly relative to the body during measurement, thereby improving the accuracy of the sensor 22 measurement.

[0059] Compared with the traditional bracelet in which the host is set in the belt, the terminal device in this embodiment, when worn on the arm, if the belts of both are at the same tightness. The host 2 in the terminal device is mainly subjected to the force applied by the belt 1 toward the center of the arm, which can make the host 2 fit on the arm more firmly; while in the traditional bracelet, the two ends of the host are mainly subjected to the tension applied by the belt along its own length, and the combined force of the two tensions can form a force toward the center of the arm, which is obviously smaller than the force applied by the belt 1 on the host 2 in the above terminal device. Therefore, compared with the host in the traditional bracelet, the host 2 in the terminal device can be more firmly against the user's body, ensuring that the sensor 22 in the host 2 has a higher measurement accuracy.

[0060] It should be noted that the present application aims to provide a terminal device that can improve the firmness of the main unit 2 to fit the body when in use, ensure that the sensor 22 therein does not move significantly relative to the body during measurement, and then improve the measurement accuracy of the sensor 22 in the main unit 2. Therefore, the specific structure of the belt 1, as well as the type, quantity, and setting position of the sensor 22, are not described in detail. In actual applications, the belt 1 can be a strip-shaped belt, which forms a closed loop through a connector, and the size can also be adjusted by the connector. For example, the connector can be a magnetic buckle, Velcro, etc. The belt 1 can also be set as a closed loop belt, and the size can also be adjusted by setting the belt to an elastic material.

[0061] Specifically, in this embodiment, the limiting portion 31 is a frame covering the outer periphery of the main body 2; the left end of the connecting frame 3 is formed with a connecting portion connected to the first end of the belt body 1, and the left end of the connecting frame 3 is formed with a clamping portion clamped with the second end of the belt body 1. Figure 3a and Figure 3b In this embodiment, the connecting frame 3 is a rectangular frame as a whole, which can be wrapped around the outer periphery of the host 2 to limit the host 2.

[0062] The connecting portion at the left end of the connecting frame 3 is a first connecting ring 71 in the shape of a strip, and the first end of the belt body 1 is hinged on the first connecting ring 71. The clamping portion at the left end of the connecting frame 3 is a first clamping block 61 in the shape of a strip, and a first clamping groove 51 in the shape of a hook is formed at the second end of the belt body 1. After the first clamping groove 51 is clamped on the first clamping block 61, the entire belt body 1 can form a closed ring structure, which is convenient for wearing on the user's body.

[0063] In other embodiments, the left end of the connecting frame 3 and the first end of the belt body 1 can also be hinged in the form of a rotating shaft and an axial hole, and accordingly, the above-mentioned connecting portion is the rotating shaft or the axial hole. For example, a rotating shaft is provided at the left end of the connecting frame 3, and an axial hole is provided at the first end of the belt body 1, and the rotating shaft is inserted into the axial hole to realize the rotation connection between the connecting frame 3 and the belt body 1.

[0064] A second card slot 52 is formed on the inner side of the frame of the connecting frame 3, and a second card block 62 is formed on the side of the host 2. When the second card block 62 is stuck in the second card slot 52, the host 2 can be more firmly set in the connecting frame 3, further improving the stability of the host 2 when in use, and the card connection method also facilitates the assembly and disassembly of the terminal device.

[0065] In other embodiments, the connecting frame 3 may also be configured as a frame that is U-shaped, circular, or in any other shape as a whole, and the limiting function of the host 2 can be realized by ensuring that the frame can cover the outer periphery of the host 2. Alternatively, the limiting portion 31 in the connecting frame 3 may also be configured as a contact surface that fits the host 2, and the host 2 and the connecting frame 3 are bonded together by bonding, which can also improve the stability of the host 2 when in use.

[0066] In the above, the clamping part is the first clamping block 61, and the second end of the belt body 1 is clamped and fixed to the connecting frame 3 through the first clamping groove 51 on the belt body 1. In other embodiments, the clamping part can also be set as the first clamping groove 51, and the first clamping block 61 is set on the belt body 1, which can also realize the clamping and fixing of the second end of the belt body 1 and the connecting frame 3. Similarly, the second clamping block 62 can also be set on the inner side of the frame, and the second clamping groove 52 can be set on the side of the host 2, which can also realize the clamping and fixing of the connecting frame 3 and the host 2.

[0067] In addition, in other embodiments, a clamping portion may be provided at the left end of the host 2, and the second end of the belt body 1 may be clamped at the left end of the host 2, so as to achieve the above functions.

The firmness of the connection between the host 2 and the belt body 1 can also be increased. For example, a patch is disposed on the inner side of the belt body 1 at the periphery of the first hole 41, and a magnet is disposed in the host 2, so that the magnetic connection between the two can be achieved. For another example, a magnet is disposed in the belt body 1 or the host 2, and correspondingly, the material of the host 2 or the belt body 1 is set to ferromagnetic metal, so that the magnetic connection between the two can also be achieved.

[0069] As an embodiment, the protrusion 21 on the main body 2 is engaged with the first hole 41 , which can further increase the firmness of the connection between the main body 2 and the belt body 1 .

[0070] As an implementation method, Fig.17 and Fig.18 As shown, the protrusion 21 on the main unit 2 is snapped together with the first hole 41, which can further increase the firmness of the connection between the main unit 2 and the belt body 1. Specifically, outwardly protruding fourth clamping blocks 64 are provided on both sides of the protrusion 21, and a corresponding fourth clamping groove 54 is provided in the first hole 41. When the protrusion 21 is assembled in the first hole 41, the fourth clamping block 64 and the fourth clamping groove 54 are firmly snapped together, ensuring that the connection between the main unit 2 and the belt body 1 is more firmly secured.

[0071] Furthermore, a perspective layer opposite to the display screen is provided on the side of the first hole 41 away from the host 2. The user can observe the information displayed on the display screen through the perspective layer. In a specific embodiment, the perspective layer can be used as a transparent film attached to the surface of the display screen to protect the display screen.

[0072] In another specific embodiment, the perspective layer can be a part of the belt body 1, that is, the first hole 41 is a blind hole, the display screen is arranged in the blind hole, and the part of the belt body 1 opposite to the display screen is a light-transmitting structure. For example, the thickness of the perspective layer is set to be much smaller than the thickness of other parts of the belt body 1. When the display screen is off, the appearance of the perspective layer is the same as the appearance of other parts of the belt body 1, so that the terminal device has a relatively simple appearance. When the display screen is displayed, information can also be displayed to the outside through the perspective layer.

[0073] Embodiment 2

[0074] like Figures 5a to 7 As shown, in this embodiment, a terminal device is disclosed, which includes a belt body 1, a host 2 and a connecting frame 3. A first hole 41 is provided on the belt body 1. The host 2 is arranged on the inner side of the belt body 1, and a protrusion 21 opposite to the first hole 41 is provided on one surface of the host 2, and a sensor is provided on another surface and / or inside for measuring various body indications. The connecting frame 3 is also connected to the inner side of the belt body 1, and a limiting portion 31 for accommodating the host 2 is formed on the connecting frame 3, and the host 2 is arranged in the limiting portion 31.

[0075] In this embodiment, the above-mentioned terminal device is used to illustrate its usage by taking a wristband as an example. Specifically, when wearing the terminal device, the host 2 is set in the limiting portion 31 in the connecting frame 3, and then the connecting frame 3 is connected to the inner side of the belt body 1, and the protrusion 21 on the host 2 is placed in the first hole 41 from the inner side of the belt body 1, and finally the belt body 1 is worn on the user's body. After the protrusion 21 is set in the first hole 41, the belt body 1 can form a radial position restriction on the host 2 along the first hole 41, and the connection between the connecting frame 3 and the belt body 1 can further increase the stability of the host 2. The superposition of the force applied by the belt body 1 to the host 2 toward the center of the body can make the host 2 fit more firmly on the body, ensuring that the sensor therein will not have obvious relative movement with the body during measurement, thereby improving the accuracy of the sensor measurement.

[0076] Compared with the traditional bracelet in which the host is set in the belt, the terminal device in this embodiment, when worn on the arm, if the belts of both are at the same tightness. The host 2 in the terminal device is mainly subjected to the force applied by the belt 1 toward the center of the arm, which can make the host 2 fit on the arm more firmly; while in the traditional bracelet, the two ends of the host are mainly subjected to the tension applied by the belt along its own length, and the combined force of the two tensions can form a force toward the center of the arm, which is obviously smaller than the force applied by the belt 1 on the host 2 in the above terminal device. Therefore, compared with the host in the traditional bracelet, the host 2 in the terminal device can be more firmly pressed against the user's body, ensuring that the sensor in the host 2 has a higher measurement accuracy.

[0077] It should be noted that the present application aims to provide a terminal device that can improve the firmness of the main unit 2 to fit the body when in use, ensure that the sensors therein do not move significantly relative to the body when measuring, and then improve the measurement accuracy of the sensors in the main unit 2. Therefore, the specific structure of the belt 1, as well as the types, quantity, and setting positions of the sensors, are not described in detail. In actual applications, the belt 1 can be a strip-shaped belt that forms a closed loop through a connector, and the size can also be adjusted by the connector. For example, the connector can be a magnetic buckle, Velcro, etc. The belt 1 can also be set as a closed loop belt, and the size can also be adjusted by setting the belt to an elastic material.

[0078] Specifically, in this embodiment, the connecting frame 3 is bonded to the inner side of the belt body 1, and a second hole 42 opposite to the first hole 41 is formed on the connecting frame 3. The protrusion 21 on the host 2 is arranged in the first hole 41 and the second hole 42. By bonding, the firmness of the connection between the connecting frame 3 and the belt body 1 can be improved, thereby improving the stability of the host 2 on the inner side of the belt body 1.

[0079] As an implementation mode, in this embodiment, the connecting frame 3 is a U-shaped frame as a whole, the limiting portion 31 is a third card slot 53 arranged relatively on the inner side of the connecting frame 3, and the side of the host 2 is formed with a third card block 63 having the same shape as the third card slot 53.

[0080] In other embodiments, the connecting frame 3 may also be configured as a frame that is rectangular, circular or in any shape as a whole, and the limiting of the host 2 can be achieved by ensuring that it has a frame that can cover the outer periphery of the host 2. Alternatively, the limiting portion 31 in the connecting frame 3 may also be configured as a contact surface that fits the host 2, and the host 2 and the connecting frame 3 are bonded together by bonding, which can also improve the stability of the host 2 when in use.

For example, a patch is disposed on the inner side of the belt body 1 at the periphery of the first hole 41, and a magnet is disposed in the host 2, so that the magnetic connection between the two can be achieved. For another example, a magnet is disposed in the belt body 1 or the host 2, and correspondingly, the material of the host 2 or the belt body 1 is set to ferromagnetic metal, so that the magnetic connection between the two can also be achieved.

[0083] As an implementation method, Fig.17 and Fig.18 As shown, the protrusion 21 on the main unit 2 is snapped together with the first hole 41, which can further increase the firmness of the connection between the main unit 2 and the belt body 1. Specifically, outwardly protruding fourth clamping blocks 64 are provided on both sides of the protrusion 21, and a corresponding fourth clamping groove 54 is provided in the first hole 41. When the protrusion 21 is assembled in the first hole 41, the fourth clamping block 64 and the fourth clamping groove 54 are firmly snapped together, ensuring that the connection between the main unit 2 and the belt body 1 is more firmly secured.

[0084] As an embodiment, a display screen is provided on the outer surface of the protrusion 21 , which can display relevant data measured by the sensor in the host 2 and / or other data in the host 2 such as time.

[0085] Furthermore, a perspective layer opposite to the display screen is provided on the side of the first hole 41 away from the host 2. The user can observe the information displayed on the display screen through the perspective layer.

[0087] Embodiment 3

[0088] like Figures 8a to 10 As shown, in this embodiment, a terminal device is disclosed, which includes a belt body 1, a host 2 and a connecting frame 3. A first hole 41 is provided on the belt body 1. The host 2 is arranged on the inner side of the belt body 1, and a protrusion 21 opposite to the first hole 41 is provided on one surface of the host 2, and a sensor is provided on another surface and / or inside for measuring various body indications. The connecting frame 3 is also connected to the inner side of the belt body 1, and a limiting portion 31 for accommodating the host 2 is formed on the connecting frame 3, and the host 2 is arranged in the limiting portion 31.

[0089] In this embodiment, the above-mentioned terminal device is used to illustrate its usage by taking a wristband as an example. Specifically, when wearing the terminal device, the host 2 is set in the limiting portion 31 in the connecting frame 3, and then the connecting frame 3 is connected to the inner side of the belt body 1, and the protrusion 21 on the host 2 is placed in the first hole 41 from the inner side of the belt body 1, and finally the belt body 1 is worn on the user's body. After the protrusion 21 is set in the first hole 41, the belt body 1 can form a radial position restriction on the host 2 along the first hole 41, and the connection between the connecting frame 3 and the belt body 1 can further increase the stability of the host 2. The superposition of the force applied by the belt body 1 to the host 2 toward the center of the body can make the host 2 fit more firmly on the body, ensuring that the sensor therein will not have obvious relative movement with the body during measurement, thereby improving the accuracy of the sensor measurement.

[0090] Compared with the traditional bracelet in which the host is set in the belt, the terminal device in this embodiment, when worn on the arm, if the belts of both are at the same tightness. The host 2 in the terminal device is mainly subjected to the force applied by the belt 1 toward the center of the arm, which can make the host 2 fit on the arm more firmly; while in the traditional bracelet, the two ends of the host are mainly subjected to the tension applied by the belt along its own length, and the combined force of the two tensions can form a force toward the center of the arm, which is obviously smaller than the force applied by the belt 1 on the host 2 in the above terminal device. Therefore, compared with the host in the traditional bracelet, the host 2 in the terminal device can be more firmly pressed against the user's body, ensuring that the sensor in the host 2 has a higher measurement accuracy.

[0091] It should be noted that the present application aims to provide a terminal device that can improve the firmness of the main unit 2 to fit the body when in use, ensure that the sensors therein do not move significantly relative to the body when measuring, and then improve the measurement accuracy of the sensors in the main unit 2. Therefore, the specific structure of the belt 1, as well as the types, quantity, and setting positions of the sensors, are not described in detail. In actual applications, the belt 1 can be a strip-shaped belt that forms a closed loop through a connector, and the size can also be adjusted by the connector. For example, the connector can be a magnetic buckle, Velcro, etc. The belt 1 can also be set as a closed loop belt, and the size can also be adjusted by setting the belt to an elastic material.

After the belt body 1 passes through one second connecting ring 72, it passes through the other second connecting ring 72 around the outer surface of the connecting frame 3, so that the main part of the connecting frame 3 and the host 2 are both located on the inner side of the watchband. This connection method between the connecting frame 3 and the belt body 1 ensures the firmness of the connection between the host 2 and the watchband, so that when the terminal device is worn, the host 2 can fit firmly on the user's body.

[0093] As an implementation mode, in this embodiment, the connecting frame 3 is a U-shaped frame as a whole, the limiting portion 31 is formed by a third card slot 53 arranged relatively on the inner side of the connecting frame 3, and a third card block 63 having the same shape as the third card slot 53 is formed on the side of the host 2. After the third card block 63 is snapped into the third card slot 53, the host 2 can be more firmly set in the connecting frame 3, further improving the stability of the host 2 when in use, and the snap-on method also facilitates the assembly and disassembly of the terminal device.

[0094] In other embodiments, the connecting frame 3 may also be configured as a frame that is rectangular, circular or in any shape as a whole, and the limiting of the host 2 can be achieved by ensuring that it has a frame that can cover the outer periphery of the host 2. Alternatively, the limiting portion 31 in the connecting frame 3 may also be configured as a contact surface that fits the host 2, and the host 2 and the connecting frame 3 are bonded together by bonding, which can also improve the stability of the host 2 when in use.

[0095] In other embodiments, a relative third card block 63 may be provided on the inner side of the connecting frame 3, and a third card slot 53 having the same shape as the third card block 63 may be provided on the side of the host 2.

The firmness of the connection between the host 2 and the belt body 1 can also be increased. For example, a patch is disposed on the inner side of the belt body 1 at the periphery of the first hole 41, and a magnet is disposed in the host 2, so that the magnetic connection between the two can be achieved. For another example, a magnet is disposed in the belt body 1 or the host 2, and correspondingly, the material of the host 2 or the belt body 1 is set to ferromagnetic metal, so that the magnetic connection between the two can also be achieved.

Specifically, outwardly protruding fourth clamping blocks 64 are provided on both sides of the protrusion 21, and a corresponding fourth clamping groove 54 is provided in the first hole 41. When the protrusion 21 is assembled in the first hole 41, the fourth clamping block 64 and the fourth clamping groove 54 are firmly snapped together, ensuring that the connection between the main unit 2 and the belt body 1 is more firmly secured.

[0098] As an embodiment, a display screen is provided on the outer surface of the protrusion 21 , which can display relevant data measured by the sensor in the host 2 and / or other data in the host 2 such as time.

[0099] Furthermore, a perspective layer opposite to the display screen is provided on the side of the first hole 41 away from the host 2. The user can observe the information displayed on the display screen through the perspective layer. In a specific embodiment, the perspective layer can be used as a transparent film attached to the surface of the display screen to protect the display screen.

[0100] In another specific embodiment, the perspective layer can be a part of the belt body 1, that is, the first hole 41 is a blind hole, the display screen is arranged in the blind hole, and the part of the belt body 1 opposite to the display screen is a light-transmitting structure. For example, the thickness of the perspective layer is set to be much smaller than the thickness of other parts of the belt body 1. When the display screen is off, the appearance of the perspective layer is the same as the appearance of other parts of the belt body 1, so that the terminal device has a relatively simple appearance. When the display screen is displayed, information can also be displayed to the outside through the perspective layer.
