Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following describes each embodiment of the present application in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in various embodiments of the present application in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.

In the assembled watch band, a plurality of watch band units each composed of a connector, a fastener, and other components are assembled in sequence. When the watchband is assembled and formed, the plurality of fasteners are sequentially connected together through the plurality of connecting pieces. The buckling pieces of the two adjacent watchband units are connected with the same connecting piece, so that the sequential assembly of the watchband units is realized.

In some cases, the connectors of the watchband unit are in the form of push rods that connect to the fasteners. As shown in fig. 1 and 2, the connector 301, the fastener 302, the pusher 303, the spring 304, the fixed pin 305, the movable pin 306, and the insert pin 307 are assembled in a predetermined form, and when these components are assembled, the fixed pin 305 and the connector 301 are fixed by welding, the spring 304 is compressed between the fixed pin 305 and the movable pin 306, the pusher 303 is fitted over the movable pin 306, and a part of the pusher 303 is exposed from the connector 301. Thus, prior to assembly of the connector 301 to the fasteners 302, the runner bar 303 is pushed toward the side adjacent to the pins 305 to retract the runner bars 306, thereby allowing the connector 301 to be brought into engagement with the fasteners 302 and the pins 305 to be brought into engagement with the mating holes in the side of the fasteners 302. At this time, the connection member 301 and the fastening member 302 are coupled as shown in FIG. 3. After the connector 301 reaches a specific mating position, the pushing rod 303 is released, and the moving pin 306 is pushed into the mating hole on the other side of the fastener 302 by the elastic restoring force of the spring 304, so as to assemble the connector 301 and the fastener 302. When detaching, the push rod 303 is pushed to the side close to the fixed needle 305.

In the band unit adopting the structure shown in fig. 1 and 2, the fixing pin cannot move in the connector, and the assembly with the fastener is realized by controlling the retraction and the extension of the fixing pin in the connector. During the assembly process of the connector and the fastener, the push rod is required to be pushed to enable the movable needle to retract, the fixed needle is firstly inserted into the matching hole on one side of the fastener, and then the movable needle is inserted into the matching hole on the other side of the fastener by loosening the push rod. Not only the assembly process is complicated, need reserve great space in the connecting piece moreover to the installation push rod makes the push rod can drive the needle and retract inside the center pillar, is unfavorable for reducing the width size of watchband.

In order to reduce the occupation of space while facilitating the assembly of a watch band, some embodiments of the present application provide a watch band unit. The connecting piece of the watchband unit adopts a bilateral telescopic form, namely, two pins in the connecting piece can move in the connecting piece so as to realize retraction or extension. The push rod component is eliminated, when the connecting piece is assembled with the buckling piece, the two contact pins are simultaneously pressed on the surface of the buckling piece, and then the connecting piece is plugged into a specific assembly position, so that the two contact pins are respectively connected with the matching holes on the two sides of the buckling piece under the pushing of the elastic piece.

The structure of the watchband unit provided by some embodiments of the present application is described below with reference to fig. 4 and 5, and fig. 6 is a partial cross-sectional structural schematic view of the watchband unit before the assembly of the center pillar and the fastener is completed.

As shown in fig. 4 and 5, some embodiments of the present application provide a watchband unit, which includes a connector 10 and a fastener 20 rotatably disposed on the connector 10; the connecting piece 10 is provided with a through hole 11 extending along a first direction, and a first pin 12 and a second pin 13 limited in the through hole 11 along the first direction, the first pin 12 and the second pin 13 are connected through an elastic piece 14, a limiting piece 15 sleeved on the second pin 13 is arranged in the through hole 11, the limiting piece 15 is used for limiting the second pin 13 in the through hole 11 along the opposite direction of the first direction, and the first pin 12 and the second pin 13 respectively partially penetrate through the through hole 11 and are rotatably connected with a buckling piece 20.

The connecting element 10 and the fasteners 20 are the main parts of the watch band unit, and the connecting element 10 connects the two fasteners 20 together, thereby forming the watch band. Meanwhile, the rotating connection between the connecting element 10 and the fastening elements 20 can enable the two fastening elements 20 connected together by the connecting element 10 to rotate relatively to a certain degree, so that the watch band can be straightened or bent after being connected with the display main body of the wearable device.

The through hole 11 is a through hole provided in the connector 10, and the through hole 11 is used for mounting the first pin 12, the second pin 13 and other components, so that the connector 10 can be assembled with the fastener 20.

The first pin 12 and the second pin 13 are cylindrical bodies disposed in the through hole 11 of the connector 10. The first pin 12 and the second pin 13 partially penetrate through the through hole 11 respectively so as to be rotatably connected with the fastener 20. The first pin 12 and the second pin 13 are limited in the through hole 11 along the first direction, that is, the first pin 12 and the second pin 13 cannot be separated from the through hole 11 along the first direction. In the first direction, i.e. the assembling direction of the first pin 12 and the second pin 13, the first pin 12 and the second pin 13 can be inserted into the through hole 11 of the connector 10 along the first direction. It can be understood that there are various ways to limit the first pin 12 and the second pin 13 from being separated from the through hole 11 along the first direction, for example, a stepped structure may be provided on the inner walls of the first pin 12 and the through hole 11, a protrusion and a groove may be provided on the inner walls of the first pin 12 and the through hole 11, or a stop member may be provided on one of the inner walls of the first pin 12 and the through hole 11 to cooperate with the other.

The first pin 12 and the second pin 13 are connected through the elastic member 14, that is, the elastic member 14 is disposed between the first pin 12 and the second pin 13. The elastic member 14 may be a coil spring, a disc spring or a spring plate, and the elastic restoring force of the elastic member 14 can push the first pin 12 and the second pin 13 to extend out of the center pillar and to be matched with the fastener 20 after the first pin 12 and the second pin 13 retracted into the connector 10 lose the external constraint.

The stopper 15 is disposed in the through hole 11 of the connector 10 for restricting the second pin 13 in the through hole 11 in a direction opposite to the first direction, i.e., preventing the second pin 13 from being removed from the through hole 11 in the direction opposite to the first direction. The stopper 15 may be annular, hollow semi-cylindrical, or block-shaped.

Thus, unlike the watchband unit in the form of a push bar, both the first pin 12 and the second pin 13 can move within the connector 10 to achieve retraction or extension. During assembly of the connector 10 and the fasteners 20, the connector 10 can be plugged into the final mating position by retracting the first pins 12 and the second pins 13 only by surface constraint of the fasteners 20. The first pin 12 and the second pin 13 can complete the mating with the fastener 20 under the elastic restoring force of the elastic member 14 after losing the constraint of the surface of the fastener 20.

The position-limiting portion 101 of the first pin 12 can be engaged with the inner wall of the through hole 11 to prevent the first pin 12 from being separated from the through hole 11 along the first direction. The position-limiting portion 101 of the second pin 13 can be engaged with the position-limiting member 15 disposed in the through hole 11, so as to prevent the second pin 13 from being separated from the through hole 11 in the opposite direction of the first direction. The guide portion 102 of the first pin 12 and the guide portion 102 of the second pin 13 are both configured to cooperate with the elastic member 14, so that the elastic member 14 can deform along the guide portion 102 when the first pin 12 and the second pin 13 move.
