In one embodiment, referring to <FIG> and <FIG>, the wearable device further includes a lock mechanism <NUM>, and the wearable assembly <NUM> includes a watch band <NUM> and a bracket <NUM> connected to the watch band <NUM>. The second body is detachably connected to the bracket <NUM> through the lock mechanism <NUM>. When the second body <NUM> is detached from the bracket <NUM>, the second body <NUM> is folded outwards along a direction of the connecting means <NUM> away from the first body <NUM> to be unfolded from the first body <NUM>. The number of the lock mechanism <NUM> is at least one, and in specific applications, the number of the lock mechanism <NUM> is one, two or more. The bracket <NUM> defines a groove <NUM>, and the groove <NUM> is used for receiving the display device <NUM> after being covered. Two opposite ends of the bracket <NUM> are respectively provided with one lock mechanism <NUM> detachably inserted into the end of the bracket <NUM>, and two ends of the lock mechanism <NUM> are respectively located in the bracket <NUM> and the second body <NUM>.

Of course, in other embodiments, the first body <NUM> is detachably connected to the bracket <NUM> through the lock mechanism <NUM>, or one end of the lock mechanism <NUM> is located between the first body <NUM> and the second body <NUM>, for example, grooves are provided on the first body <NUM> and the second body <NUM> respectively. When the first body <NUM> and the second body <NUM> are covered with each other, the grooves on the first body <NUM> and the second body <NUM> form a connecting hole for receiving the lock mechanism <NUM>, so that one end of the lock mechanism <NUM> can be inserted into the connecting hole.

In the present invention, in conjunction with <FIG>, <FIG>, and <FIG>, the lock mechanism <NUM> includes: a lock button <NUM>, a first return spring <NUM>, a lock buckle <NUM>, and a second return spring <NUM>. One end of the lock button <NUM> is inserted into the bracket <NUM>; two ends of the first return spring <NUM> are respectively connected to the lock button <NUM> and the bracket <NUM>; both ends of the lock buckle <NUM> are respectively penetrated through the bracket <NUM> and the second body <NUM> and abut against an end of the lock button <NUM> passing through the bracket <NUM>; and two ends of the second return spring <NUM> are respectively connected to the lock buckle <NUM> and the second body <NUM>. The other end of the lock button <NUM> can extend out of the bracket <NUM>, and it can also be located in the bracket <NUM>.

Understandably, when it extends out of the bracket <NUM>, it can be directly squeezed by hand, and when it is in the bracket <NUM>, it can be squeezed with the help of a tool.

When the display device <NUM> is detached, one end of the lock button <NUM> is squeezed by hand or a tool, so that the other end of the lock button <NUM> squeezes the lock buckle <NUM>, and the lock buckle <NUM> is separated from the bracket <NUM>, therefore the display device <NUM> can be detached from the bracket <NUM>. The lock button <NUM> squeezes the first return spring <NUM> during a squeezing process, and the lock buckle <NUM> squeezes the second return spring <NUM> during the squeezing process, so that the first return spring <NUM> and the second return spring <NUM> are respectively in a compressed state. When the display device <NUM> is taken out, the lock button <NUM> returns to an original position under the action of the first return spring <NUM>, and the lock catch <NUM> returns to an original position under the action of the second return spring <NUM>.

In one embodiment, referring specifically to <FIG>, in order to prevent the lock button <NUM> from overly squeezing the first return spring <NUM> and causing the first return spring <NUM> to lose its resilience, the lock button <NUM> includes an abutment portion <NUM> and an insertion portion <NUM> that are connected in turn, and the bracket <NUM> defines an abutment groove <NUM> and an insertion groove <NUM> that are communicated in turn. The insertion portion <NUM> is inserted into the insertion groove <NUM> to abut against an end of the lock buckle <NUM>, and an end of the abutment portion <NUM> abuts against a groove wall of the abutment groove <NUM> to limit a pressing position of the lock buckle <NUM>. When the abutment portion <NUM> is pressed, the abutment portion <NUM> drives the insertion portion <NUM> to move inward together, so that the insertion portion <NUM> squeezes the lock buckle <NUM>. When the abutment portion <NUM> abuts against the groove wall of the abutment groove <NUM>, the abutment portion <NUM> will no longer move inward.

In one embodiment, referring to <FIG> and <FIG>, when one end of the first return spring <NUM> is inserted into the abutment portion <NUM>, and the other end of the first return spring <NUM> abuts against the groove wall of the abutment groove <NUM>, in order to avoid the lock button <NUM> being released from the bracket <NUM> under the action of the resilience of the first return spring <NUM>, the lock mechanism <NUM> further includes a limiter <NUM>.

A through hole <NUM> is defined in the abutment portion <NUM>, and a first connecting groove <NUM> communicating with the abutment groove <NUM> is defined in the bracket <NUM>. One end of the abutment portion <NUM> passes through the first connecting groove <NUM> and the abutment groove <NUM> in turn and abuts against the lock buckle <NUM>. The limiter <NUM> passes through the first connecting groove <NUM> and the through hole <NUM> in turn, a middle part of the limiter <NUM> is located in the through hole <NUM>. Both ends of the limiter <NUM> are respectively located in the first connecting groove <NUM>, and two opposite sides of the limiter <NUM> are respectively abut against the through hole <NUM> to limit a rebounding position of the lock button <NUM>, thereby avoiding the lock button <NUM> being released from the bracket <NUM>. Specifically, the limiter <NUM> is a vertically positioned elastic sheet, the elastic sheet is in an "S" shape, a middle part of the elastic sheet is located in the through hole <NUM> of the abutment portion <NUM>, both ends of the elastic sheet are located in the connecting groove, and both sides of the elastic sheet abut against the through hole <NUM>.

Of course, in other embodiments, when one end of the first return spring <NUM> is fixedly connected to the abutment portion <NUM>, and the other end of the second return spring <NUM> is fixedly connected to the groove wall of the abutment groove <NUM>, the limiter <NUM> is not required to limit a rebounding position of the lock button <NUM>. Since the first return spring <NUM> is fixedly connected to the lock button <NUM> and the bracket <NUM>, the first return spring <NUM> can pull the lock button <NUM> while rebounding.

In one embodiment, the lock buckle <NUM> includes a connecting portion <NUM> and a moving portion <NUM> connected in turn, and an end of the connecting portion <NUM> away from the moving portion <NUM> is inserted into the insertion groove <NUM> to abut against the insertion portion <NUM>, the second body <NUM> defines a second connecting groove <NUM> and an receiving groove <NUM> communicated in turn, and two ends of the second return spring <NUM> are respectively abut against the connecting portion <NUM> and a groove wall of the second connecting groove <NUM>. Specifically, the connecting portion <NUM> is located in the second connecting groove <NUM>, and when the button of the lock buckle <NUM> is pushed, the moving portion <NUM> is pushed to move in the receiving groove <NUM>.

When both ends of the second return spring <NUM> respectively abut against the connecting portion <NUM> and the groove wall of the second connecting groove <NUM>, the lock mechanism <NUM> further includes a non-enclosed clamping member <NUM>. The clamping member <NUM> is sleeved on an end of the moving portion <NUM> away from the connecting portion <NUM>. Specifically, a card slot is defined at a position where the moving portion <NUM> is connected to the clamping member <NUM>, and the clamping member <NUM> is clamped in the card slot. When the lock button <NUM> is squeezed, the connecting portion <NUM> can be pushed to move by the clamping member <NUM> because the clamping member <NUM> is not enclosed, so that the connecting portion <NUM> is separated from the insertion groove <NUM>, and the second return spring <NUM> is compressed. When the display device <NUM> is detached, the lock buckle <NUM> recovers under the action of the rebounding of the second return spring <NUM>, and the buckle will not be separated from the second body <NUM> due to the action of the clamping member <NUM>.
