The device terminal 1 includes but is not limited to a button assembly 10 and an outer shell 20. The button assembly 10 is fixedly connected to the outer shell 20. Depending on the strength of the pressing force applied by the user to the button assembly 10, the device terminal 1 of the present invention can achieve different functions. In one or more embodiments, when the user applies a pressing force of less than or equal to 100g (pressure grams) to the button assembly 10, the device terminal 1 will perform the screen off function; when the user applies a pressing force greater than 100g and less than 200g to the button assembly 10, a dialog box will pop up on the screen of the device terminal 1 and ask the user whether to execute shutdown. In alternative embodiments, the device terminal 1 of the present invention can also realize any other suitable functions through the button assembly 10, which can be adjusted according to actual design requirements.

In one or more embodiments, the fixing portion 21 is a substantially rectangular parallelepiped shell, and is fixed to the inner wall (not marked in the figure) of the outer shell 20. The button assembly 10 can pass through the fixing portion 21 and form a fixed connection with the fixing portion 21, thereby being fixed to the outer shell 20. In alternative embodiments, the fixing portion 21 can also be any other suitable structure, as long as it can fix the button assembly 10 to the outer shell 20.

[0019] like Figures 1 to 3 As shown, in one or more embodiments, the button assembly 10 includes a conductive member 11, a button body 12 and a piezoresistive sensor 13. The conductive member 11 and the piezoresistive sensor 13 are fixed inside the outer shell 20. The button body 12 is partially located outside the outer shell 20 so that the user can press it.

[0020] like Figure 2 and Figure 3As shown, the button assembly 10 includes a conductive member 11. In one or more embodiments, the conductive member 11 is a steel sheet. In alternative embodiments, the conductive member 11 may also be a thin sheet made of any other suitable metal, as long as it can accurately and stably transmit the pressing force from the button body 12 to the piezoresistive sensor 13. The conductive member 11 has a first side surface 111 and a second side surface 112 opposite to each other. Figure 3 In the orientation shown, the first side surface 111 is the right side surface relative to the figure, and the second side surface 112 is the left side surface relative to the figure.

[0021] Continue to see Figure 2 and Figure 3 In one or more embodiments, the conductive member 11 has a guide groove 113. The guide groove 113 is provided on the first side surface 111 and extends vertically outward from the first side surface 111. In an alternative embodiment, the guide groove 113 may also extend vertically inward from the first side surface 111 for a shorter distance, as long as the button body 12 of the button assembly 10 can be positioned. Alternatively, the guide groove 113 may be omitted. In one or more embodiments, an internal thread (not shown in the figure) is provided inside the guide groove 113.

[0022] Continue to see Figure 2 and Figure 3 In one or more embodiments, the conductive member 11 also has two fixed pages (not marked in the figure).

The fixing page is closely attached to the fixing portion 21 of the outer shell 20, and is fixed to the fixing portion 21 of the outer shell 20 by the screw member 30, so that the conductive member 11 is fixed inside the outer shell 20. In an alternative embodiment, any other suitable number of fixing pages can also be arranged on the conductive member 11, and the fixing page can be arranged at any suitable position of the conductive member 11, as long as it can be connected to the fixing portion 21 of the outer shell 20 by the screw member 30. Alternatively, the setting of the fixing page can also be eliminated, as long as a suitable number of through holes are arranged at suitable positions of the conductive member 11, so that the screw member 30 fixes the conductive member 11 to the fixing portion 21 of the outer shell 20 through the through holes.

[0023] like Figures 1 to 3 As shown, the button assembly 10 includes a button body 12. The button body 12 includes a first end 121 and a second end 122 opposite to each other.

In alternative embodiments, the cross section of the head 123 may also be elliptical, rectangular, or any other suitable shape. The head 123 is located outside the outer shell 20, and there is a gap h between the head 123 and the outer shell 20 (see Figure 3 ). It can be understood that the gap h is the pressing stroke of the button body 12. In one or more embodiments, the gap h is 0.1 mm. In alternative embodiments, the gap can also be any suitable value between 0.1-0.5 mm, which can be adjusted according to actual design requirements.

In an alternative embodiment, the setting of the external thread on the button body 12 can also be cancelled, and the setting of the internal thread on the conductive member 11 can be cancelled accordingly, as long as it is ensured that the first end 121 of the button body 12 can be closely attached to the first side surface 111 of the conductive member 11. In one or more embodiments, the outer diameter of the rod 124 is smaller than the outer diameter of the head 123. In an alternative embodiment, the outer diameter of the stem 124 may also be equal to the outer diameter of the head 123. The specific structure of the button body 12 may be adjusted according to actual design requirements.
