All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The key of the invention is to provide a crown, and the key rod of the crown is convenient to assemble. Another core of the present invention is to provide a wrist-worn device comprising the above crown, whose key-bar of the crown is easy to assemble.

Referring to fig. 1-5, fig. 1 is a sectional view of a crown according to an embodiment of the present invention after assembly; FIG. 2 is a cross-sectional view from another perspective of the crown shown in FIG. 1; FIG. 3 is a schematic structural view of the case of FIG. 1; FIG. 4 is a schematic structural view of the guide cylinder; fig. 5 is a sectional view of the first elastic member, the clip member and the guide cylinder after assembly.

The invention provides a crown, which mainly comprises a key rod 11, a body, a first elastic piece 21 and the like.

Specifically, one end of the key lever 11 is used for connecting with the key cap 12, and the other end is assembled on the body, so that the key cap 12 is mounted under the switching action of the key lever 11.

The body is used for being fixedly connected with the inner side of the watch case 6, and the body mainly plays a role in bearing and fixing other parts.

The body is provided with a first jack for inserting the key rod 11, and it can be understood that after the body is fixed on the inner side of the watchcase 6, the first jack on the body corresponds to a mounting hole for mounting a crown on the watchcase 6, so that the key rod 11 is inserted into the first jack of the body from the outer side of the watchcase 6.

Simultaneously, the peripheral part of key-press rod 11 is equipped with the recess, the body is equipped with first elastic component 21, first elastic component 21 can be followed the axis direction of the first jack of perpendicular to and stretch out and draw back, and first elastic component 21 is equipped with joint piece 22 towards the one end of first jack, joint piece 22 be used for with the recess joint on the key-press rod 11, in order to realize the fixed of key-press rod 11 and body, avoid key-press rod 11 to break away from the body, also promptly, joint piece 22 plays the spacing effect of axial to key-press rod 11.

It should be noted that, in order to avoid that the snap member 22 locks the key lever 11 to be dead and affect the pressing of the key cap 12, the size of the groove is larger than the size of the snap member 22 along the axial direction of the first insertion hole.

That is, after the engaging member 22 is engaged in the groove, there is still a certain gap margin in the groove to ensure that the key lever 11 can be pressed.

It can be understood that, during installation, the key lever 11 is inserted into the first jack, and the key lever 11 is moved along the first jack, when the key lever 11 is moved to the position of the clamping member 22, the clamping member 22 is extruded by the key lever 11, the clamping member 22 extrudes the first elastic member 21, and then the first elastic member 21 is contracted to drive the clamping member 22 to move the key lever 11, so as to facilitate the key lever 11 to continue moving; when the recess on the key lever 11 aligns joint spare 22, joint spare 22 is in the recess is gone into to the elasticity of first elastic component 21 under restoring force effect to it is spacing to carry out the axial to the key lever 11, realizes being connected of key lever 11 and body, avoids breaking away from the body according to key lever 11.

Therefore, the crown provided by the invention utilizes the combined action of the first elastic piece 21 and the clamping piece 22 as the limiting structure of the key rod 11, the first elastic piece 21 and the clamping piece 22 can be assembled on the body in advance, and then the key rod 11 is installed, namely, the first elastic piece 21 and the clamping piece 22 exist, the assembly of the key rod 11 is not influenced, meanwhile, the axial limiting of the key rod 11 can be realized, and the effect of blindly assembling the key rod 11 is achieved.

Compared with the prior art that the key rod 11 is fixed by adopting a clamp spring type limiting structure, the assembly is convenient, the assembly complexity is reduced, and the limiting structure is not required to be installed after the key rod 11 is installed in place, so that the pre-installation of functional accessories such as the sensor 33 and the key switch 32 is facilitated, and the alignment of the sensor 33 and the key rod 11 and the coaxiality of the key switch 32 and the key rod 11 are facilitated. It can be understood that, after the clamping member 22 is bounced into the groove under the action of the first elastic member 21, because there is still a certain gap margin in the groove, when the key cap 12 is pressed and the key rod 11 is moved, the groove can be moved relative to the clamping member 22 along with the movement of the key rod 11, that is, in the moving process of the key rod 11, the position of the clamping member 22 in the groove changes, for example, as shown in fig. 1 and 2, when the key rod 11 is assembled in place, in a natural state, the clamping member 22 is in contact with the inner side wall of the groove far from the key cap 12, at this time, under the action of the clamping member 22, the key rod 11 cannot be moved to the right side (the direction shown in fig. 1 and 2), that is, the key rod 11 cannot be pulled out from the first insertion hole, so that the key rod 11 can be prevented from being separated from the body.

When the key cap 12 is pressed, the key rod 11 moves to the left, the groove moves to the left, and the axial position of the clamping piece 22 is kept unchanged, so that the position of the clamping piece 22 in the groove is changed.

Obviously, the clearance margin in the groove needs to satisfy the moving distance when the key lever 11 is pressed, and preferably, the clearance margin in the groove just satisfies: when the key cap 12 is pressed in place, the clamping piece 22 is just contacted with the inner side wall of the groove close to the key cap 12. At this time, the groove has a certain axial limiting effect, and the accuracy of the moving distance of the key rod 11 is ensured.

It should be noted that, the specific structure of the first elastic member 21 is not limited in the present invention, as long as it has certain elasticity and can be extended and contracted along the axial direction perpendicular to the first insertion hole under the action of external force, for example, the first elastic member 21 may be a spring or an elastic block.

In view of the convenience of the arrangement of the first elastic member 21, on the basis of the above-described embodiment, the first elastic member 21 is embedded in the guide cylinder 23, and the guide cylinder 23 is fixedly connected to the body.

That is to say, the first elastic element 21 in this embodiment is connected to the body through the guide cylinder 23, and the guide cylinder 23 can play a role in guiding and limiting the extension and retraction of the first elastic element 21, so as to avoid the first elastic element 21 from deflecting during extension and retraction.

It can be understood that the end of the first elastic member 21 away from the clamping member 22 is fixedly connected with the guide cylinder 23.

Of course, it is also possible to have a scheme in which: the body is equipped with first elastic component 21 mounting hole, is equipped with the guide post in the first elastic component 21 mounting hole, and the peripheral part of guide post is located to first elastic component 21 cover to the outer wall that utilizes the guide post and the inner wall of first elastic component 21 mounting hole play the spacing effect of circumference to first elastic component 21, lead to the concertina movement of first elastic component 21 simultaneously.

It should be noted that, in this embodiment, a specific connection manner of the guide cylinder 23 and the body is not limited, for example, the guide cylinder 23 and the body may be fixed by welding or by interference fit.

Preferably, on the basis of the above embodiment, the guide cylinder 23 is screwed with the body, and the outer end of the guide cylinder 23 is provided with a tool hole for facilitating screwing.

That is, the outer periphery of the guide cylinder 23 is provided with external threads, and the guide cylinder 23 can be directly screwed into the threaded hole of the body by using a tool hole by means of an attachment tool during attachment.

In addition, the present invention does not limit the specific structure of the snap-in member 22, as long as it can compress the first elastic member 21 under the pressing action of the key lever 11, and can be snapped into the groove under the action of the first elastic member 21.

On the basis of the above embodiment, the clip member 22 includes a bump or a slider, and the slider is provided with a chamfer toward the inner side of the installation direction of the key lever 11.

It can be understood that, when the snap member 22 is a ball, since the ball is spherical, the ball makes point contact with the key lever 11 after the key lever 11 presses the ball, and the friction force is small.

Of course, the clamping member 22 may also be a sliding block, so that the sliding block can be clamped with the groove more stably and reliably.

It can be understood that, when the clamping member 22 is a slider, the slider is provided with a chamfer toward the inner side of the mounting direction of the key lever 11, and when the key lever 11 moves to the position of the slider, the key lever 11 first contacts with the chamfer to generate a thrust on the chamfer, so that the slider generates an extrusion force on the first elastic member 21.

At this time, preferably, one side of the slider facing the key lever 11 is provided with an arc-shaped surface, so that the slider can be attached to the cylindrical key lever 11, which is favorable for realizing the rotation of the key lever 11.

In addition, the shape of the concave groove is not limited in the present invention, and in order to enable the key lever 11 to rotate within a certain angle range, the concave groove is an annular groove or an arc-shaped groove on the basis of the above-described embodiments.

It can be understood that when the groove is an arc-shaped groove, the rotatable angle range of the key lever 11 is limited by the arc length of the arc-shaped groove; when the groove is an annular groove, the key lever 11 can be rotated through a full 360-degree turn.

Further, the specific number of the first elastic members 21 is not limited in the present invention, for example, the number of the first elastic members 21 may be one, as long as the key lever 11 can be locked to prevent the key lever 11 from being separated from the body.

Preferably, the number of the first elastic members 21 is at least two, and more than two first elastic members 21 are preferably uniformly distributed along the circumferential direction of the key lever 11.

It can be understood that when the grooves are arc-shaped grooves, the first elastic members 21 are disposed in one-to-one correspondence with the grooves.

When the groove is an annular groove, the first elastic member 21 may be disposed arbitrarily in the circumferential direction of the key lever 11.

It can be understood that, because the groove is an arc-shaped groove or a closed annular groove, when the key lever 11 is rotated, the groove can rotate relative to the snap member 22 along with the rotation of the key lever 11, that is, the circumferential position of the snap member 22 in the groove changes during the rotation of the key lever 11.

When the recess is the arc wall, the corner scope of key lever 11 does: one inner side wall in the circumferential direction of the groove is in contact with the snap member 22 to the other opposite inner side wall in the circumferential direction of the groove is in contact with the snap member 22.

When the groove is an annular groove, the key lever 11 can rotate 360 degrees, and in the process of rotating the key lever 11 in a whole circle, the groove rotates 360 degrees, and the position of the clamping piece 22 remains unchanged, which is equivalent to that the clamping piece 22 rotates a circle along the groove. That is, the present embodiment can satisfy the rotation of the key lever 11 within a certain angle range.

In addition, based on the situation that the key lever 11 is fixed by using a circlip structure in the prior art, the sensor 33, the key switch 32, other functional accessories and the like can only be bulk-stacked in the watch case 6, that is, when a new structure needs to be introduced into the crown, any mountable space is found in the watch case 6, and the east wall and the west wall are usually dismantled, so that the functional accessories related to the crown are scattered and have no seal, and the assembly is inconvenient and the reliability is low.
