An embodiment of a first aspect of the present application provides a key structure of an electronic device, where the electronic device may be a wearable electronic device such as a smart watch, a smart bracelet, a smart glasses, and the like.

Referring to fig. 1 to 3, the electronic device 200 includes a housing 201, and the key structure 100 is mounted on the housing 201.

Referring to fig. 3 to 5, in one embodiment of the present application, a key structure 100 includes a sleeve 10, a key 20, and a first magnet 30.

The sleeve 10 is configured to be inserted through the housing 201, i.e. the sleeve 10 is mounted on the housing 201, and one side of the sleeve 10 is located outside the housing 201, the other side of the sleeve 10 is located inside the housing 201, and the side of the sleeve 10 located outside the housing 201 is provided with the first groove 11.

The key 20 is sleeved on one side of the sleeve 10, which is positioned outside the shell 201, and the key 20 can move relative to the sleeve 10, so that metal fragments are easily generated between one side of the key 20 facing the sleeve 10 and the sleeve 10 due to friction.

The first magnet 30 is disposed in the sidewall of the sleeve 10, and under the magnetic force of the first magnet 30, the first magnet 30 is used for adsorbing the metal fragments falling into the first groove 11 to the bottom of the first groove 11, so that the metal fragments can leave the inner side of the key 20 and be deposited at the bottom of the first groove 11 through the attraction between the first magnet 30 and the metal fragments, and the pressing or rotating malfunction is avoided. It is understood that the metal chips may be chips containing metals such as iron, cobalt, nickel, etc.

The above-mentioned key structure 100 includes a sleeve 10, a key 20 and a first magnet 30, the sleeve 10 is configured to be disposed through the casing 201, the key 20 is sleeved on one side of the sleeve 10 located outside the casing 201, and one side of the sleeve 10 located outside the casing 201 is provided with a first groove 11, since the side wall of the sleeve 10 is internally provided with the first magnet 30, metal fragments generated in the process of moving the key 20 relative to the sleeve 10 can be adsorbed on the bottom of the first groove 11 under the action of the first magnet 30, so as to avoid the problem that the metal fragments are deposited in the gap between the key 20 and the sleeve 10 to cause the possible pressing or rotating malfunction of the key 20, thereby solving the technical problem that the metal fragments generated in the process of moving the key 20 of the electronic device 200 in the prior art are easily deposited in the gap between the key 20 and the sleeve 10, and thus cause the rotating or pressing malfunction.

Referring to fig. 5, in an embodiment of the present application, the first groove 11 is located at the contact position between the key 20 and the sleeve 10. In this way, most of the metal fragments generated during the movement of the key 20 relative to the sleeve 10 can fall directly into the first recess 11, reducing the likelihood of metal fragments being deposited in the gap between the key 20 and the sleeve 10.

In the present embodiment, the key 20 covers at least part of the first groove 11, that is, the projection of the key 20 in the axial direction of the sleeve 10 and the projection of the first groove 11 in the axial direction of the sleeve 10 overlap at least partially, that is, the key 20 may be disposed to completely cover the first groove 11, or the key 20 may be disposed to cover part of the first groove 11, which is not limited herein.

Thus, the second groove 12 can provide a space for storing dirt brought by the outside, and further avoid poor pressing or rotating functions; in addition, the second groove 12 is close to the housing 201 relative to the first groove 11, so that the groove wall of the second groove 12 can be used to stop dirt from entering the first groove 11, thereby reducing the possibility of external dirt entering the inner side of the key 20.

It will be appreciated that in other embodiments of the present application, the second groove 12 may be omitted, and the first groove 11 stores dirt from the outside and metal fragments generated during the movement of the key 20 relative to the sleeve 10, and the shape and size of the first groove 11 may be designed according to the requirement, which is not limited herein.

In one embodiment of the present application, the key 20 is movable relative to the housing 201 in the axial direction of the sleeve 10, and the key 20 is rotatable relative to the housing 201 about the axial direction of the sleeve 10.

That is, when the user presses the key cap 21, the key cap 21 drives the transmission shaft 22 to approach the main board until contacting the main board, thereby realizing the function corresponding to the pressing operation. Correspondingly, after the function adjustment corresponding to the pressing operation is finished, the user removes the action of pressing the key cap 21, and the key cap 21 and the transmission shaft 22 move in the direction away from the main board until reset.

In this embodiment, the outer wall of the sleeve 10 abuts against the housing 201 and passes through the housing 201, the sleeve 10 is provided with a mounting channel 13 extending along the axial direction thereof, the transmission shaft 22 movably passes through the mounting channel 13, and the transmission shaft 22 abuts against the side wall of the mounting channel 13 in the axial direction, i.e. the transmission shaft 22 abuts against the inner wall of the sleeve 10 in the axial direction and can rotate and move relative to the sleeve 10.
