The process of collecting the human body electrocardio function signal through the key is as follows, a user places fingers on the outer end face of the key cap 310 to form a trigger signal, the key cap 310 is conducted to the key post 320 through the abutting spring 340, the key post 320 is in contact with the elastic sheet 110, and then the signal is transmitted to the sensing circuit board 10, so that the collection of the human body electrocardio function signal can be realized. In this embodiment, the metal key 300 can also be reused as a trigger key of the touch circuit board 20, so as to implement functions corresponding to the touch circuit board 20, such as screen locking, volume control, power on/off, and the like.

The insulating inlay 420 in this embodiment is disposed around the inner wall of the accommodating hole 4100, and the insulating inlay 420 may be made of plastic, specifically, the insulating inlay 420 and the main body 410 are integrally formed by injection molding.

The embedded portion 421 further has an accommodating groove 4210 for accommodating the key cap 310 of the metal key 300.

Because the key cap is a small metal piece, the key in the embodiment needs to be subjected to nano injection molding on the periphery of the key cap to form the insulating inlay, so that the key has higher cost. Under the extreme condition, for example after the user swims, under the condition that has water in the wrist-watch button, water can regard as conducting medium for metal button and center casing metal switch on, and then have the possibility that can't normally pass through button measurement human electrocardio function signal under this operating mode. Because the round plastic is torn open to the button cap, lead to the partial area relative size of metal in the middle of the button cap less, the partial area of metal will influence the experience that the user used, electrocardio function signal detection performance can't maximize, and the metal area is big more in theory, has the promotion to electrocardio function signal detection performance. In the electronic device of the present embodiment, on the basis of the previous embodiment, a layer of plastic is peeled off from the middle frame (or the main body) (i.e., the insulating inlay 420 and the main body 410 are integrally injection molded), so that the entire key is made of metal, and thus the problems still existing in the previous embodiments can be successfully solved.

According to the electronic equipment in the embodiment of the application, the shell can effectively solve the problem that a user feels pain when the electrocardio function signal detection function fails under an extreme working condition (such as just after swimming), and under the working condition that the key is fully immersed in water, conducting devices such as a key cap, an abutting spring, a key column and the like can still be insulated from the middle frame (main body), so that the insulation reliability is high; secondly, the cost can be reduced by two thirds due to the fact that the key is made into an all-metal scheme; the third advantage of the scheme is that the conducting area of the surface of the key is increased, and the conducting area can be increased by one third due to no plastic, so that the detection performance of the electrocardio function signal is improved. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
