A crown and a wrist-worn device having the same

Abstract

The invention discloses a crown and a wrist-worn device with the crown. The crown comprises: a button rod provided with an external thread; The first jack for rod insertion; the first captive nut fixed on the body; the second captive nut that is unidirectionally locked with the first captive nut, and the second captive nut is provided for connecting with the outer The internal threads of the thread fit connection, the screwing direction of the external threads and the internal threads are the same as the locking directions of the first captive nut and the second captive nut. The second captive nut can be pre-assembled on the body through the first captive nut, and then the key rod is installed. The existence of the second captive nut does not affect the assembly of the key rod, and can realize the axial direction of the key rod The position is limited to achieve the effect of blindly installing the key rod. Compared with the prior art, the assembly is convenient and the complexity of assembly is reduced. The wrist-worn device includes the above-mentioned crown and has the above-mentioned beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of wearable devices, and more specifically, relates to a watch crown. In addition, the present invention also relates to a wrist-worn device comprising the above crown. Background technique [0002] The crown is a common component of wristband wearable devices. For example, with the continuous improvement of smart watch functions, the crown has been widely used and has become the mainstream configuration of smart watches, so that the rotation and / or pressing of the crown can be used to achieve alignment. Smart watch control. [0003] In the crown in the prior art, the key rod is fixed by a special circlip structure, so as to limit the axial position of the key rod. [0004] When assembling, it is necessary to insert the key rod into the case from the outside first, and then insert a spring structure specially used for axially limiting the key rod from the inside of the case to realize the fixing of...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from this that it is inconvenient to assemble the button rod with a spring-like structure, so that functional accessories such as sensors and key switches can only be stacked and installed in the case after the button rod is fixed by the ring-type structure, resulting in The overall structure of the crown is loose and cumbersome to assemble
