In other words, the pressing surface 2111 is formed on the surface of the pressing portion 211 facing away from the pressing groove 2112, and the pressing surface 2111 is the exposed surface of the key 21 for pressing.

The engaging portion 212 is configured to position the key 21 or the key assembly 20, i.e., the engaging portion 212 is used to cooperate with the casing 10 to position the key assembly 20. When the pressing portion 211 is inserted into the opening 110, the engaging portion 212 abuts against the inner surface of the housing 10. Meanwhile, the engaging portion 212 may be fixed to the housing 10 by screwing, inserting, snapping, bonding, welding, or the like. In one embodiment, the engaging portion 212 and the housing 10 can be detachably connected.

The engaging portion 212 surrounds at least a part of the outer periphery of the pressing groove 2112, and the engaging portion 212 and the pressing surface 2111 are spaced apart in the depth direction of the pressing groove 2112 (i.e., the pressing direction of the key 21). In other words, the engaging portion 212 is disposed adjacent to the notch of the pressing groove 2112, and when the pressing portion 211 is exposed out of the housing 10, the engaging portion 212 can abut against the inner wall of the housing 10. Specifically, the engaging portion 212 may be substantially in the shape of a visor, and the engaging portion 212 may be substantially in the shape of a peak, a full visor, or other visor structure.

It is understood that the circumferential sidewall of the pressing groove 2112 generally refers to a sidewall connected to the pressing surface 2111 in a bent manner, and the groove cavity of the pressing groove 2112 generally refers to a cavity defined by the circumferential sidewall and the pressing surface 2111.

It is understood that the pressing portion 211 and the engaging portion 212 generally form a step-like structure, the pressing surface 2111 may be a top surface of a step exposed outside the housing 10 for pressing operation, and the surface of the engaging portion 212 adjacent to the pressing surface 2111 may be a bottom surface of a step abutting against the inner surface of the housing 10. In other words, the surface of the engaging portion 212 close to the pressing surface 2111 and the pressing surface 2111 are provided at an interval in the depth direction of the pressing groove 2112.

In one embodiment, the engaging portion 212 is substantially annular and surrounds the outer periphery of the pressing groove 2112, i.e., the engaging portion 212 is substantially in a full-brim structure. The surface of the engaging portion 212 facing away from the pressing surface 2111 and the end surface of the pressing groove 2112 facing away from the pressing surface 2111 are coplanar. Of course, in another embodiment, the surface of the engaging portion 212 facing away from the pressing surface 2111 and the end surface of the pressing groove 2112 facing away from the pressing surface 2111 may not be coplanar.

The contact portion 213 is provided on the side of the pressing portion 211 facing away from the pressing surface 2111, that is, the contact portion 213 extends from the bottom wall of the pressing groove 2112 in the direction away from the pressing surface 2111. In one embodiment, the abutting portion 213 and the circumferential sidewall of the pressing groove 2112 are provided at an interval.

The abutting portion 213 is configured to abut against a component requiring a pressing operation inside the monitoring device 100, for example, the abutting portion 213 may abut against the switch element. When the pressing operation is performed, the pressing portion 211 is deformed to move the abutting portion 213, and the abutting portion 213 is moved to act on the switch element or other components, thereby implementing the input function of the key 21.

The support 22 is generally an annular sheet-like structure or an annular plate-like structure. Of course, the supporting member 22 may have other shapes, which will not be described in detail.
