DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The core of the present invention is to provide a wrist-worn device which effectively utilizes the strap space.

[0041] It should be noted that when an element is referred to as "fixing" another element, it can be directly on the other element or there can also be a centered element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a centered element at the same time. In addition, the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] A specific embodiment of the wrist-worn device provided by the present invention includes a device body 1 and a strap.

[0044] The device body 1 includes a watch case 11 and a main control component 12 disposed in the watch case 11. The main control component 12 includes a mainboard 121 and functional components that perform corresponding functions of the wrist-worn device, such as a heart rate sensor, a microphone, a Bluetooth and other components. The watch case 11 includes a watch ear 111, and a mounting groove 112 is provided on the watch ear 111 to connect a watch strap. The watch strap includes a mounting post 34, and the mounting post 34 is detachably plugged and fixed in the mounting groove 112, thereby realizing a detachable connection between the watch strap and the device body. Among them, when the mounting post 34 is connected to the mounting groove 112, the mounting post 34 and the mounting groove 112 remain relatively stationary, but the portion of the watch strap 11 located outside the mounting groove 112 is movable, for example, to adjust the degree of bending, etc., to ensure wearing comfort.

[0045] An expandable functional component is provided in the inner cavity 341 of the mounting column 34, and a watch band connector is provided through the mounting column 34, and the watch band connector is electrically connected to the expandable functional component. A watch case connection hole 16 is provided through the watch case 11, and a main body connector is fixedly provided in the watch case connection hole 16, and the main body connector is electrically connected to the main control component 12. One end of the main body connector exposed to the watch case 11 and one end of the watch band connector exposed to the mounting column 34 are in contact with each other to be electrically connected, so that the expandable functional component is electrically connected to the main control component 12 via the watch band connector and the main body connector. At the same time, the electrical connection between the expandable functional component and the main control component 12 can be completed in the process of assembling the watch band to the device body 1.

[0046] The hollow setting of the mounting post 34 on the strap realizes the effective utilization of the strap space, and the expandable functional component is set at the mounting post 34 connected to the lug 111 of the device body 1. When in use, no matter how the main part of the strap outside the lug 111 is bent, it will not affect the normal use of the expandable functional component; the mounting post 34 and the lug 111 are plugged in and out to realize the detachable connection between the strap and the device body 1, and the electrical connection between the expandable functional component and the main control component can be completed during the process of assembling the strap to the device body 1, which is convenient for assembly.

[0047] Furthermore, the watch strap includes a strap body 2 and a quick release block 3. In the extending direction of the watch strap, one end of the quick release block 3 is provided with a mounting post 34, and the other end is detachably fixedly connected to the strap body 2. When only the strap body 2 needs to be removed, for example, when the strap body 2 is damaged and needs to be repaired, it is not necessary to remove the entire watch strap from the watch case 11, and only the strap body 2 can be removed from the quick release block 3. The quick release block 3 remains connected to the device body 1, which can prevent the quick release block 3 from being repeatedly disassembled and assembled to cause damage to the strap connector and the main body connector.

[0048] Among them, preferably, Figure 5 , Figure 7 , Figure 8 and Fig.11 As shown, the quick release block 3 has a slot 35 at one end away from the mounting post 34 in the direction of the strap extension, and a locking hole 36 connected to the slot 35 is formed through the quick release block 3. The strap body 2 is embedded with a locking nut 21 perpendicular to the direction of the strap extension, and two locking nuts 21 may be provided. Figure 7 As shown, the strap body 2 is inserted into the slot 35 and the locking hole 36 is directly opposite to the locking nut 21, the threaded column 222 of the locking screw 22 extends through the locking hole 36 and is threadedly connected to the locking nut 21, and the head 221 of the locking screw 22 is located in the locking hole 36. The locking hole 36 limits the head 221 of the locking screw 22 in the extension direction of the strap to prevent the strap body 2 from slipping out of the slot 35 along the extension direction of the strap. By directly screwing the strap body 2 and the quick release block 3, the quick release and quick installation of the strap body 2 can be achieved. Of course, in other embodiments, the quick release block 3 and the strap body 2 can be connected by a buckle to achieve a detachable fixed connection.

[0049] For further information, please refer to Figure 4 The mounting groove 112 extends perpendicular to the extension direction of the strap. Figure 6 As shown, the installation slot 112 has an installation opening 115 at one end in its extending direction and a retaining wall 113 at the other end. The installation post 34 can enter the installation slot 112 through the installation opening 115 and slide to a set assembly position ( Figure 6The mounting post 34 is set to abut against the retaining wall 113 to achieve plug-in assembly of the mounting post 34 and the mounting groove 112. Since the mounting groove 112 is open on one side in the sliding direction, the mounting post 34 can be assembled in place by sliding the mounting post 34 sideways to abut against the retaining wall 113 during the assembly process, which is convenient for assembly.

[0050] Furthermore, the main connector is an elastic pogo pin 14, the elastic expansion direction of the pogo pin 14 is perpendicular to the extension direction of the mounting groove 112, and the free end of the pogo pin 14 extends into the mounting groove 112 in a free state. Figure 2 and Figure 3 , pogopin 14 is arranged in the case connection hole 116 and has an interference fit with the case connection hole 116, one end of pogopin 14 located in the case 11 is welded with pogopin FPC welding wire 13, and the other end of pogopin FPC welding wire 13 is welded to the main board 121 (PCBA board) of the main control component 12. After welding, pogopin 14 and the case 11 are further fixed with glue. A connecting groove 38 is provided on the outer surface of the mounting column 34, and the free end of the strap connector is arranged in the connecting groove 38. Specifically, Fig. 9 As shown, a connecting groove 38 is provided on the outer surface of the mounting column 34, and a watch band connecting hole 37 is penetrated by the mounting column 34, and the two ends of the watch band connecting hole 37 are respectively connected to the inner cavity 341 of the mounting column 34 and the connecting groove 38, and the watch band connector is fixed in the watch band connecting hole 37, specifically, it can be fixed by glue, and the free end of the watch band connector faces the connecting groove 38 but does not protrude from the outer surface of the mounting column 34 through the connecting groove 38, and the watch band connector forms a recess relative to the outer surface of the mounting column 34.

[0051] During the process of the mounting post 34 sliding in the mounting groove 112 for assembly, the mounting post 34 can press the pogo pin 14 to retract. When the mounting post 34 slides in the mounting groove 112 to a set assembly position (i.e., the mounting post 34 abuts against the retaining wall 113), as shown in FIG. Figure 3 As shown, the pogo pin 14 pops out toward the mounting post 34 and extends into the connecting groove 38 so that the pogo pin 14 electrically contacts the watch band connector.

[0052] Preferably, the end surface of the mounting column 34 that abuts against the retaining wall 113 can be inclined relative to the extension direction of the mounting groove 112, so that the free end of the pogopin 14 can be smoothly pushed back toward the inside of the watch case 11 during the sliding of the mounting column 34 along the extension direction of the mounting groove 112. In addition, the circumferential surface of the connecting groove 38 and the circumferential surface of the pogopin 14 can both be cylindrical surfaces with the axis perpendicular to the extension direction of the mounting groove 112. When the connecting groove 38 and the pogopin 14 are plugged in, the circumferential surface of the connecting groove 38 fits with the circumferential surface of the pogopin 14, thereby preventing the pogopin 14 from slipping out of the connecting groove 38 after being plugged in the connecting groove 38.

[0053] Due to the plug-in fit between the pogo pin 14 and the connecting groove 38, the pogo pin 14 and the connecting groove 38 can limit the mounting column 34 and the mounting groove 112 in the extending direction of the mounting groove 112. Figure 2 In the orientation shown, the mounting post 34 slides downward into the mounting groove 112 during the assembly process, and after installation, the pogo pin 14 and the connecting groove 38 are plugged in and fit to prevent the mounting post 34 from sliding upward out of the mounting groove 112. In addition, if the quick release block 3 needs to be removed, the pogo pin 14 can be removed from the device body 1 first, and then the mounting post 34 can be slid out of the mounting groove 112.

[0054] Furthermore, the slot 114 of the mounting slot 112 is disposed on a side away from the watch case 11 in the direction in which the watch band extends. In the slot wall of the mounting slot 112, two portions close to the slot 114 are close together obliquely in the direction away from the watch case 11, so as to constrain the mounting post 34 in the mounting slot 112 in the direction in which the watch band extends, and the rest of the watch band extends out of the mounting slot 112 through the slot 114. Figure 5 As shown, in the direction perpendicular to the extension of the mounting groove 112, the cross section of the mounting groove 112 is an arc-shaped line segment with a central angle greater than 180° (e.g., 200°). Accordingly, the mounting post 34 is a cylindrical structure. In the extension direction of the watch strap, the mounting groove 112 can half-wrap the mounting post 34. The opening size of the notch 114 of the mounting groove 112 is smaller than the radial size of the mounting post 34, so that Figure 5 In this orientation, the mounting post 34 cannot fall out to the right under the constraint of the notch 114 of the mounting groove 112. In addition, the notch 114 of the mounting groove 112 clamps the portion of the strap located in the notch 114, thereby effectively preventing the mounting post 34 from rotating in the mounting groove 112 as the strap body bends, thereby preventing the stability of the connection between the strap connector and the main body connector from being affected. In addition, the retracted notch 114 also limits the installation direction of the mounting post 34, that is, the mounting post 34 needs to slide sideways from the mounting opening 115 through the mounting groove 112 to be installed, and cannot be installed arbitrarily through the notch 114.

[0055] Furthermore, if Figure 8 , Fig.15 and Fig.16 As shown, the mounting column 34 is provided with an assembly hole connecting the inner cavity 341 with the outside, and the assembly hole is detachably fixedly connected with an end cap 32, which can be specifically fixed by snapping or threading. The arrangement of the end cap 32 can facilitate the disassembly and assembly of the expandable functional components in the inner cavity 341. In addition, as Figure 6 As shown, the end wall of the mounting column 34 that abuts against the retaining wall 113 is composed of the end cover 32. After the mounting column 34 is assembled in the mounting groove 112, the retaining wall 113 and the main body of the mounting column 34 clamp the end cover 32, which can effectively prevent the end cover 32 from falling off. Fig.15 and Fig.16 As shown, the end cap 32 has a certain inclination relative to the extension direction of the mounting groove 112, so that the end cap 32 can push the pogo pin 14 to retract during the assembly process of the mounting column 34.

[0056] Furthermore, an inclined surface 39 is provided on the end of the mounting post 34 opposite to the end cover 32. In the extension direction of the strap and in the direction away from the device body 1, the inclined surface 39 gradually inclines toward the other end of the mounting post 34. The end cover 32 is parallel to the extension direction of the strap, thereby facilitating the distinction between the two ends of the mounting post 34 and determining which end of the mounting post 34 needs to be inserted into the mounting groove 112, thereby avoiding the mounting post 34 from being inserted upside down.

[0057] Furthermore, the expandable functional component includes a strap battery 33, and the strap connector is a battery conductive block 31, so as to utilize the space in the strap to increase the endurance of the wrist-worn device. Fig.12 , Fig.13 and Fig.14 As shown, a battery positive electrode 331 and a battery negative electrode 332 are protruding from the outer surface of the strap battery 33. Correspondingly, two battery conductive blocks 31 that are in contact with the battery positive electrode 331 and the battery negative electrode 332 for electrical conduction are fixed on the mounting column 34. The two battery conductive blocks 31 are electrically connected to the two pogo pins 14 on the device body 1 respectively.

[0058] The wrist-worn device usually includes two straps, and the expandable functional components in the two straps may both include the above-mentioned strap battery 33 , or the expandable functional components in only one strap include the above-mentioned strap battery 33 .

[0059] The expandable functional component may only include the strap battery 33, and the inner cavity 341 is designed to conform to the strap battery 33 to prevent the strap battery 33 from shaking in the inner cavity 341. Figure 5 and Fig.12As shown, the strap battery 33 is a cylindrical structure, and correspondingly, the inner cavity 341 is a cylindrical structure that fits the outer surface of the strap battery 33. In addition, a limiting groove extending along the axial direction of the inner cavity 341 can be provided on one of the strap battery 33 and the inner cavity 341, and a matching limiting protrusion is provided on the other, so that the strap battery 33 is prevented from rotating in the inner cavity 341 by plugging and fitting the limiting groove and the limiting protrusion.

[0060] Furthermore, the expandable functional component is electrically connected to the main board 121 in the main control component 12, and the charging structure on the device body 1 is electrically connected to the main board 121, so that the strap battery 33 is charged through the charging structure, the main board 121, the pogopin FPC welding line 13, the pogopin 14, and the battery conductive block 31, that is, the strap battery 33 can be charged without removing it.

[0061] Furthermore, the main control component 12 also includes a main battery 122 electrically connected to the main board 121. Batteries are provided in both the device body 1 and the watch case 11, which can greatly improve the battery life compared to wrist-worn devices in the prior art that only provide batteries in the device body 1. In addition, the main battery 122 can be charged using the same charging structure as the strap battery 33.

[0062] The assembly process of the wrist-worn device provided in this embodiment is as follows:

[0063] Band assembly: first assemble the clasp 23 to the band body 2. The clasp 23 can connect two band bodies 2. Insert the band body 2 into the quick release block 3 and then tighten the two locking screws 22. Install the band battery 33 into the mounting post 34. Snap the end cover 32 onto the mounting post 34 to protect the band battery 33 from falling out of the inner cavity 341. Finally, fix the battery conductive block 31 to the quick release block 3 by dispensing glue. Alternatively, after assembling the band battery 33, the end cover 32, and the battery conductive block 31 to the quick release block 3, fix the quick release block 3 to the band body 2 with the locking screws 22.

[0064] Main body assembly: After the main battery 122 is fixedly connected to the main board 121 by welding and fixing with the battery double-sided adhesive 123, the two pogopins 14 are fixed to the watch case 11 by interference fit and glue dispensing, and the pogopin FPC welding wire 13 is welded to the pogopin 14.

[0065] Overall assembly: Assemble the watch strap to the watch case 11 through the quick-release block 3.

[0066] Of course, in other embodiments, for setting the number of batteries, the main body battery 122 can be set only in the device body 1, and the strap battery 33 is not set in the strap. In addition, the expandable functional component is not limited to the strap battery 33. For example, it can also be set as a gravity acceleration sensor for detecting the amount of human movement. In the motion state, the gravity acceleration sensor can count steps according to the number of arm swings; or, the expandable functional component is a GPS sensor for real-time positioning of user location information; or, the expandable functional component can include at least two components, for example, the strap battery 33 and the GPS sensor, and the number of connectors can be set accordingly.

[0067] In addition, since the expandable functional component is equivalent to being separated from the outside world by a double-layer shell structure of the lug 111 and the mounting post 34, in order to prevent the material and thickness of the mounting post 34 and the lug 111 from interfering with the normal use of the expandable functional component, the expandable functional component is preferably a strap battery that supplies power to the main control component 12 through the strap connector; or, a detection component, and its detection signal does not rely on the generation of receiving and sending signals between the lug 111 and the mounting post 34 and the outside world, but generates a detection signal through its own structural changes. For example, a gravity acceleration sensor changes its own structure when sensing changes in acceleration force, thereby generating a signal, which is then transmitted to the main control component 12 through the strap connector.

[0068] As for detection components that rely on signals sent and received between the lug 111 and the mounting post 34 and the outside world to generate detection signals, such as heart rate sensors, they need to be in direct contact with the skin or maintain a small distance from the skin. When used as expandable functional components, it may be necessary to set the mounting post 34 and the lug 111 to a thinner structure, or to add through holes on the mounting post 34 and the lug 111 to connect to the outside world (preferably a waterproof film is added to the through hole), so as to ensure the normal use of such components.

[0069] Obviously, in another specific embodiment, the main body connector may not be provided in the case connection hole 16. Specifically, the watch band connector is provided as an elastic connector, and in the process of the mounting post 34 slidingly assembling in the mounting groove 112, at the initial moment, the watch band connector is pressed by the groove wall of the mounting groove 112 and is in a compressed state; when the watch band connector moves with the mounting post 34 to the case connection hole 16, the watch band connector resets and extends into the inside of the case through the case connection hole 16, and directly contacts with the corresponding components (such as electrical contacts) on the main control component 12 for electrical connection.

[0070] Obviously, in another specific embodiment, the plug-in fixation between the mounting post 34 and the mounting slot 112 may not rely on the strap connector and the main body connector. For example, the mounting post 34 and the mounting slot 112 may be fixed by magnetic attraction or by snap-fitting.

[0071] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0072] The wrist-worn device provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
