Fig. 3 is a schematic structural diagram of another smart watch 20 according to an embodiment of the present invention. As shown in fig. 3, the watch band assembly 400 may include a connector assembly 500.

The watch body 300 and the band assembly 400 are electrically connected by the connector assembly 500. The connector assembly 500 is electrically connected with the watch body 300.

Alternatively, as shown in fig. 3, the connector assembly 500 may include a first bolt 301 and a second bolt 302. The band assembly 400 can be fixed to the case of the watch body 300 by the first bolt 301 and the second bolt 302. It is understood that the band assembly 400 can be fixed to the case (e.g., a steel pin) of the watch body 300 by other means, which will not be described herein.

Alternatively, the connector assembly 500 may be movably connected to the watch body 300 so that the user can adjust the position of the watch body 300 relative to the band assembly 400 as desired.

The watch band assembly 400 may also include an extended function device 600. The extended function device 600 may be electrically connected to the connector assembly 500 via a connecting wire, such that the extended function device 600 is electrically connected to the watch body 300 to provide more functionality to the watch body 300. The extended function device 600 may be disposed on a corresponding portion of the watch band assembly 400 adjacent to the connector assembly 500. The extended function device 600 is used to provide other functions besides the functions of the watch main body 300, such as GPS, flexible battery, data storage, wireless communication, etc., so that the smart watch 20 has at least one of the above functions, which can be obtained by installing a hardware function chip having the above functions in the extended function device 600. It can be seen that the extended function device 600 may specifically be a device having a specific hardware structure, such as a GPS transceiver, a flexible battery, a flash memory, a sim card socket, and the like. It is understood that the extended function device 600 may be other types of hardware devices in the embodiment of the present invention.

Alternatively, the extended function device 600 may be detachably mounted in the band assembly 400, such as by removable screws, or may be mounted in the band assembly 400 by a secondary injection molding process.

Specifically, as shown in fig. 4, the ear side plane 300A of the watch body 300 may be provided with an extended function interface 310, and the extended function interface 310 may be configured as a sleeve-like structure, and the interface may be configured as a racetrack. The extended function interface 310 may be a pin interface or a contact interface, and is not limited in the embodiment of the present invention.

As shown in fig. 5, an extended function interface 310 is provided on the ear side plane 300A at one end of the watch main body 300. The extended function interface 310 may include a plurality of external conductive contacts 310a, and the racetrack shape of the extended function interface 310 may reduce the height of the extended function interface 310, thereby reducing the size of the watch body 300 at the ear, and the sleeve-type connection may increase the contact area between the watch band assembly 400 and the watch body 300, and reinforce the connection between the watch band assembly 400 and the watch body 300.

It is understood that, according to actual design requirements, the extended function interface 320 may be separately provided on the ear-side plane 300B on the other side of the watch main body 300, or the same extended function interface may be provided on both ear-side planes on both sides, so that the smart watch 20 has the structure of the extended function interface 310 on both ear-side planes on both sides, which is not limited herein.

As can be seen, the first end of the connector assembly 500 is connected to the extended function device 600, and the second end of the connector assembly 500 is connected to the extended function interface 310, so that the wristwatch body 300 and the band assembly 400 are electrically connected. Thereby acquiring at least one other function than the function possessed by the watch main body 300.

The smart watch 20 provided by the invention obtains at least one function except the function of the watch main body 300 through the extended function device 600 in the watchband assembly 400, and then connects the watchband assembly 400 to the watch main body 300 of the smart watch through the sleeve-type connection mode of the connector assembly 500 and the extended function interface 310, thereby expanding the function of the smart watch 20, reducing the size and the weight of the smart watch 20 and improving the wearing comfort of a user.

For example, the extended function interface 310 shown in fig. 6 may specifically further include a first circuit board assembly 310 b. The first circuit board assembly 310b may be a Flexible Printed Circuit (FPC) to improve the reliability of connection between devices and the wearing comfort of a user.

The first end of the first circuit board assembly 310b is provided with a plurality of built-in conductive contacts 310c, and the conductive contacts 310c may be provided with a Zero Insertion Force (ZIF) connector conductive contact structure, so that the conductive contacts 310c may be electrically connected with a ZIF connector of the main board of the smart watch 20.

The second end of the first circuit board assembly 310b is provided with a plurality of external conductive contacts 310d, and the conductive contacts 310d may be connected to the bottom plane of the multifunctional expansion interface 310, that is, the conductive contacts 310d are mounted on the bottom of the sleeve tube of the functional expansion interface 310, and the conductive contacts 310d are disposed outwards.

The number of the conductive contacts 310c is the same as that of the conductive contacts 310d, and the conductive contacts are in one-to-one correspondence.

Alternatively, the conductive contacts 310d may be fixed on the bottom plane of the extended function interface 310 by a double-sided adhesive tape, so as to keep the conductive contacts 310d exposed outwards, and the number of the conductive contacts at the two ends of the first circuit board assembly 310b may be increased or decreased according to the actual requirement of the design, which is not limited herein.

As shown in fig. 7, the bottom plane of the extended function interface 310 is opened with a laser cut slit 320, and the laser cut slit 320 may be a narrow slit that only allows the conductive contact 310c of the first circuit board assembly 310b to pass through, and the conductive contact 310c enters the inside of the watch main body 300 through the laser cut slit 320 to be electrically connected to the ZIF connector on the main board inside the watch main body 300. It is understood that the conductive contacts 310c may be electrically connected to the ZIF connectors on the internal motherboard in other manners.

It should be noted that the conductive contact in the embodiment of the present invention may specifically be a gold finger contact, and is not particularly limited in the embodiment of the present invention.

Fig. 8 is a schematic structural diagram of a connector assembly 500 according to an embodiment of the present invention. As shown in fig. 8, the connector assembly 500 may specifically include a connector housing 510, a terminal assembly 520, and an O-ring seal 530.

Referring to the coordinate system (x-axis, y-axis, z-axis, and origin O) in fig. 8, there are, in order from left to right in the x-axis direction, an O-ring seal 530, a connector housing 510, and a terminal assembly 520.

Illustratively, the connector housing 510 shown in fig. 9 may be made of an insulative plastic material and may be hollow to receive the terminal assembly 520. To enhance the reliability of the connection of the connector assembly 500 to the extended function interface 310, the connector housing 510 may be provided with three different height connections 510A, 510B, and 510C to increase contact with the quill tube and the inner housing at the ear, respectively.

Referring to the coordinate system in fig. 9, the order of the connection portions of the connector housing 510 is 510C, 510B, and 510A in order from left to right in the x-axis direction, and the height of the connection portion 510A of the connector housing 510 is the highest in the z-axis direction. The connecting portion 510B has the largest area, and a protrusion 510B is provided at the middle of the side surface 510a of the connecting portion. The connecting portion 510C has the lowest height, and an annular groove 510d is formed in the middle of the end surface 510C of the connecting portion 510C, and the shape of the annular groove 510d matches the shape of the O-ring seal 530. When the connector assembly 500 is connected with the extended function interface 310, a high waterproof level can be achieved through elastic deformation of the O-ring 530 after the connector assembly 510 is connected with the extended function interface 310, and meanwhile, a plurality of first through holes 510f are formed in the side surface 510d of the connecting portion so as to be combined with the terminal assembly 520, and the first through holes 520f can be racetrack-shaped. The racetrack-shaped first through hole 520f can minimize the overall height of the connector assembly 510, thereby realizing an ultra-thin design of the connector assembly 510 to meet the small size requirement of the watch on the interface.

Illustratively, as shown in fig. 10, the terminal assembly 520 may include a metal terminal 520B, a terminal bracket 520C, and a metal terminal 520A in order from left to right in the x-axis direction with reference to the coordinate system in fig. 10. The terminal assembly 520 may be manufactured by insert molding the metal dome.

The first end of terminal assembly 520 is metal terminal 520A and the first end of terminal assembly 520 is the first end of connector assembly 500, i.e., metal terminal 520A is the first end of connector assembly 500. The metal terminal 520A is electrically connected to the extended function device 600.

The second end of terminal assembly 520 is metal terminal 520B and the second end of terminal assembly 520 is the second end of connector assembly 520, i.e., metal terminal 520B is the second end of connector assembly 520. The metal terminal 520B is a folded U-shaped structure, and the bottom end surface 520a of the U-shape is a contact of the metal terminal 520B, so as to ensure that the metal terminal 520B at the second end of the terminal assembly 520 contacts the conductive contact 310d of the extended function interface 310 with the U-shaped bottom end surface 520a, and prevent the conductive contact 310d of the extended function interface 310 from being damaged by the sharp metal terminal 520B.

The number of the metal terminals 520B of the terminal assembly 520 is the same as the number of the first through holes 520f of the connector housing 510, and corresponds to each other.

For example, the metal spring between the metal terminals 520A and 520B of the terminal assembly 520 may be designed into at least one U-shaped structure (e.g., 3U-shaped structures) to provide an elastic space, a compression amount and an elastic force when the whole terminal assembly 520 is compressed by an external force, and the terminal bracket 520C is fixed on the metal spring between the metal terminals 520A and 520B to support the metal spring. It can be understood that, according to the actual design requirement, the metal elastic sheet between the metal terminal 520A and the metal terminal 520B may also be designed to have at least one N-shaped structure or M-shaped structure.

Fig. 11 is a cross-sectional view of the connector assembly 500. As shown in fig. 11, the terminal assembly 520 is built in the connector housing 510, the metal terminals 520B of the second end of the terminal assembly 520 can pass through the first through holes 510f in a one-to-one correspondence, and the metal terminals 520A of the first end of the terminal assembly 520 and the rear end portion of the terminal support 520C are externally disposed in the connector housing 510.

For example, after the terminal assembly 520 passes through the connector housing 510 through the first through hole 510f, the joint between the second end of the terminal assembly 520 and the connecting portion 510A of the connector housing 510 may be glued by using an epoxy sealant 540, so that the two are fixed together, thereby performing a waterproof sealing function. The metal terminal 520A at the first end of the terminal assembly 520 is parallel to the rear end 520D of the terminal bracket 520C with a gap 520E therebetween to electrically connect with the extended function device 600. It is understood that the metal terminals 520A of the terminal assembly 520 may also be secured to the rear end 520D of the terminal bracket 520C.
