The mounting post 34 can enter the mounting groove 112 through the mounting opening 115 and slide to a set assembly position (sliding from left to right in the orientation shown in fig. 6), where the set assembly position is specifically that the mounting post 34 abuts against the blocking wall 113, so as to realize the insertion assembly of the mounting post 34 and the mounting groove 112. Because the mounting groove 112 is opened on one side in the sliding direction, the mounting column 34 can be assembled in place only by sliding the mounting column 34 to abut against the blocking wall 113 in the assembling process, and the assembling is convenient.

Further, the main body connector is pogopin14 having elasticity, the elastic expansion and contraction direction of pogopin14 is perpendicular to the extension direction of the mounting groove 112, and the free end of pogopin14 extends into the mounting groove 112 in a free state. Referring to fig. 2 and 3, the pogopin14 is disposed in the case connecting hole 116 and is in interference fit with the case connecting hole 116, the pogopin14 is located at one end inside the case 11 and is welded with the pogopin FPC welding wire 13, the other end of the pogopin FPC welding wire 13 is welded on the main board 121(PCBA board) of the main control component 12, and after welding, the pogopin14 is further fixed to the case 11 by dispensing. The mounting post 34 is provided with a coupling groove 38 on an outer surface thereof, and the free end of the strap connector is disposed in the coupling groove 38.

In addition, the converging slot 114 also defines the mounting orientation of the mounting post 34, i.e., the mounting post 34 needs to slide laterally from the mounting opening 115 through the mounting slot 112 for installation, and cannot be installed freely through the slot 114.

Further, as shown in fig. 8, 15 and 16, the mounting post 34 is provided with an assembly hole for communicating the inner cavity 341 with the outside, and the assembly hole is detachably and fixedly connected with the end cover 32, which may be specifically fixed by clamping or screwing. By the arrangement of the end cap 32, the removal and installation of the expandable functional components in the inner cavity 341 can be facilitated. In addition, as shown in fig. 6, the end wall of the mounting post 34 abutting against the stopper wall 113 is formed by the end cap 32, and after the mounting post 34 is assembled to the mounting groove 112, the end cap 32 is held between the stopper wall 113 and the main body of the mounting post 34, so that the end cap 32 can be effectively prevented from falling off. In addition, as shown in fig. 15 and 16, the end cap 32 is inclined to the extending direction of the mounting slot 112 to facilitate the retraction of the pogopin14 pushed by the end cap 32 during the assembly of the mounting post 34.

Further, the end of the mounting post 34 opposite to the end cap 32 is provided with an inclined surface 39, the inclined surface 39 gradually inclines towards the direction close to the other end of the mounting post 34 in the extending direction of the watchband and the direction far away from the device main body 1, and the end cap 32 is parallel to the extending direction of the watchband, so that the two ends of the mounting post 34 can be distinguished conveniently, which end of the mounting post 34 needs to be inserted into the mounting groove 112 can be determined conveniently, and the reverse insertion of the mounting post 34 can be avoided.

Further, the expandability function part includes a band battery 33, and the band connector is a battery conductive piece 31 to increase the cruising ability of the wrist-worn apparatus by utilizing the space in the band. As shown in fig. 12, 13 and 14, a battery positive electrode 331 and a battery negative electrode 332 are protruded from the outer surface of the band battery 33, and accordingly, two battery conductive pieces 31 that are respectively in contact with the battery positive electrode 331 and the battery negative electrode 332 and are electrically conductive are fixedly disposed on the mounting post 34, and the two battery conductive pieces 31 are respectively electrically connected to two pogopin14 on the device body 1.

The assembly process of the wrist-worn device provided by the embodiment is as follows:

assembling the watchband: the watch buckle 23 is assembled to the belt body 2 first, and the watch buckle 23 can connect two belt bodies 2. After the band body 2 is inserted into the quick- release block 3, 2 locking screws 22 are screwed, the watchband battery 33 is loaded into the mounting column 34, the end cover 32 is buckled on the mounting column 34 through a buckle to protect the watchband battery 33 from falling out of the inner cavity 341, and finally the battery conducting block 31 is fixed on the quick-release block 3 through dispensing. Or, after assembling the watch band battery 33, the end cap 32 and the battery conducting block 31 to the quick-release block 3, the quick-release block 3 is fixed on the band body 2 by the locking screw 22.

Assembling a main body: after the main body battery 122 is fixedly connected to the main board 121 in a manner of being fixed by welding and matching with the battery double-faced adhesive tape 123, two Pogopin14 are fixed on the watchcase 11 in a manner of being glued by interference fit, and the Pogopin FPC welding wire 13 is welded on the Pogopin 14.

And (3) integral assembly: band is assembled to case 11 by quick-release block 3.

Of course, in other embodiments, for the setting of the number of batteries, it is also possible to provide only the main body battery 122 in the apparatus main body 1, and not provide the band battery 33 in the band. In addition, the extendable functional unit is not limited to the watchband battery 33, and for example, a gravitational acceleration sensor for detecting the amount of movement of the human body may be provided, and in the moving state, the gravitational acceleration sensor may count a step according to the number of times of arm swing; or the expansibility functional part is a GPS sensor for positioning the position information of the user in real time; still alternatively, the expandability functional part may include at least two kinds of parts, for example, the strap battery 33 and the GPS sensor, and the number of connectors may be set correspondingly.

In addition, since the expandable function component is separated from the outside by the double-layer case structure of the case ear 111 and the mounting post 34, in order to prevent the material and thickness of the mounting post 34 and the case ear 111 from interfering with the normal use of the expandable function component, the expandable function component is preferably a band battery that supplies power to the main control unit 12 through a band connector; or, the detecting component and the detecting signal thereof are generated independently of the transmitting and receiving signal passing through the watch ear 111 and the mounting post 34 and outside, but the detecting signal is generated by the self-structure change, for example, the gravity acceleration sensor changes the self-structure when sensing the change of the acceleration force, and then the signal is generated, and the signal is transmitted to the main control component 12 through the watch band connector.

In the case of a detection component that generates a detection signal depending on a signal transmitted and received between the outer case 111 and the mounting post 34 and the outside, such as a heart rate sensor, it is necessary to directly contact the skin or keep a small distance from the skin, and when the detection component is a scalable functional component, it may be necessary to provide the mounting post 34 and the outer case 111 with a thin structure, or to provide the mounting post 34 and the outer case 111 with a through hole (preferably, a waterproof film is provided in the through hole) for communicating with the outside, so that normal use of the component can be ensured.

Obviously, in another embodiment, the case attachment hole 16 may not have a body connector. Specifically, the watchband connector is provided with an elastic connector, and in the process that the mounting column 34 is assembled in the mounting groove 112 in a sliding mode, the watchband connector is pressed in a compression state by the groove wall of the mounting groove 112 at the initial moment; when the strap connector is moved with mounting post 34 to the case attachment opening 16, the strap connector is reset to move through the case attachment opening 16 into the case interior and directly into contact with a corresponding component (e.g., electrical contact) on the master control assembly 12 for electrical connection.

Obviously, in another embodiment, the mounting post 34 and the mounting slot 112 may be fixed by inserting and inserting without relying 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 clamping.
