Fig. 1 and fig. 2 are schematic structural diagrams of a structure and internal logic of a terminal device according to an embodiment of the present invention. The terminal device comprises lateral pressure keys 11, 12 and 13, a touch sensor 14, insulation break points 101 and 102, a capacitance processing module 19 and a pressure detection module 18, wherein:
lateral pressure keys 11, 12 and 13 are provided inside the frame of the terminal device;
the insulation break points 101 and 102 are arranged at two ends of a projection area of the lateral pressure keys 11, 12 and 13 on a frame of the terminal equipment, and a metal frame 14 cut by the insulation break points 101 and 102 on the frame is used for detecting capacitance change values generated when the lateral pressure keys 11, 12 or 13 are touched;
The metal frame 14 is connected with a capacitance processing module 19, the capacitance processing module 19 is connected with a pressure detection module 18, and the capacitance processing module 19 is used for triggering the pressure detection module 18 to detect the pressure value generated when the lateral pressure keys 11, 12 and 13 are touched when the capacitance change value detected by the metal frame 17 is greater than or equal to a preset triggering threshold value.
Alternatively, the lateral pressure keys 11, 12 and 13 may be specifically hidden lateral pressure keys in order not to affect the streamlined appearance of the terminal device, giving the user a better visual experience.
It should be understood that, in order to be able to fully detect whether the lateral pressure keys 11, 12, and 13 are touched, the projected area of the metal bezel 14 on the bezel, taken at the insulating break points 101 and 102, should be greater than or equal to the projected area of the lateral pressure keys 11, 12, and 13 on the bezel.
Alternatively, when the lateral pressure key 11, 12 or 13 is touched through the metal bezel 14, if the touch force is insufficient, that is, the pressure value generated when the lateral pressure key 11, 12 or 13 is touched is small, there may be a case that the lateral pressure key 11, 12 or 13 is touched by mistake. In this case, in order to avoid the side pressure key 11, 12 or 13 being touched by mistake, the terminal device provided by the embodiment of the present invention may further include a central processing unit 17, and the pressure detection module 18 is connected to the central processing unit 17.
The pressure detection module 18 is configured to detect a pressure value generated when the lateral pressure key 11, 12 or 13 is touched, and when the pressure detection module 18 detects that the pressure value generated when the lateral pressure key 11, 12 or 13 is touched is greater than or equal to a preset pressure threshold, the pressure detection module 18 sends a signal that the lateral pressure key 11, 12 or 13 is touched to the central processing unit 17, and the central processing unit 17 is configured to determine and process a corresponding key event based on the signal that the lateral pressure key 11, 12 or 13 is touched.

Optionally, in order for the capacitance processing module 19 to send the capacitance change value detected by the metal frame 14 to the pressure detection module 18, the capacitance processing module 19 in the embodiment of the present invention may be specifically connected to the pressure detection module 18 through a General-purpose input/output (GPIO) line; when the capacitance change value generated when the lateral pressure key 11, 12 or 13 detected by the metal frame 14 is touched is greater than or equal to a preset trigger threshold, the capacitance processing module 19 may send a signal that the lateral pressure key 11, 12 or 13 is touched to the pressure detection module 18 through a GPIO line, so as to trigger the pressure detection module 18 to detect the pressure value generated when the lateral pressure key 11, 12 or 13 is touched.
Optionally, in order to make the pressure detection module re-perform the standby state when the lateral pressure key 11, 12 or 13 stops being touched, so as to detect the pressure value generated when the lateral pressure key 11, 12 or 13 is touched again, the touch sensor 14 in the embodiment of the present invention may also send a signal carrying the lateral pressure key 11, 12 or 13 to the pressure detection module 18 through the GPIO line when detecting that the lateral pressure key 11, 12 or 13 stops being touched, so that the pressure detection module 18 re-performs the standby state.
Optionally, in order to facilitate the central processor 17 to timely acquire the signal that the lateral pressure key 11, 12 or 13 stops being touched, the pressure detection module 18 may also send the signal that the lateral pressure key 11, 12 or 13 stops being touched to the central processor 17.
Optionally, in order to facilitate the user to perform quick operations such as volume up-down and on-off on the terminal device, the lateral pressure keys in the embodiment of the present invention may include a first key 11, a second key 12, and a third key 13 according to an up-down arrangement, where the first key 11 may be a volume up key, the second key 12 may be a volume down key 12, and the third key 13 may be a power key 13. The insulation break points shown in fig. 1 may specifically include a first insulation break point 101 and a second insulation break point 102, where the first insulation break point 101 is disposed at an upper end of a projection area of the first key 11 on the frame, and the second insulation break point 102 is disposed at a lower end of a projection area of the third key 13 on the frame.
Alternatively, in order to more accurately detect which specific key of the first key 11, the second key 12, and the third key 13 is touched, the number of insulation break points in the embodiment of the present invention may be four.
As shown in fig. 3 and 4, a schematic structural diagram of another terminal device and a schematic structural diagram of internal logic according to an embodiment of the present invention are shown. Specifically, the insulation break points shown in fig. 3 may further include a third insulation break point 103 and a fourth insulation break point 103, and then the metal frame obtained by cutting the four insulation break points includes: a first metal frame 21, a second metal frame 22 and a third metal frame 23; the first metal frame 21 is a metal frame cut by the first insulation break point 101 and the third insulation break point 103 on the frame, the second metal frame 22 is a metal frame cut by the third insulation break point 103 and the fourth insulation break point 104 on the frame, and the first metal frame 21 is a metal frame cut by the second insulation break point 102 and the fourth insulation break point 104 on the frame.

In order to facilitate the first metal frame 21, the second metal frame 22 and the third metal frame 23 to transmit the signals touched by the first key 11, the second key 12 and the third key 13 to the pressure detection module 18 when detecting that the capacitance change value is greater than or equal to the preset trigger threshold, the capacitance processing module 19 in the embodiment of the present invention includes three input pins and three output pins, where the three input pins are respectively connected with the first metal frame 21, the second metal frame 22 and the third metal frame 23, and the three output pins are respectively connected with the pressure detection module 18 through a first GPIO line (i.e. GPIO1 shown in fig. 4), a second GPIO line (i.e. GPIO2 shown in fig. 4) and a third GPIO line (i.e. GPIO3 shown in fig. 4).
Alternatively, in order to determine more accurately whether the first key 11, the second key 12, or the third key 13 is touched, the embodiment of the present invention may also detect the pressure values generated when the first key 11, the second key 12, and the third key 13 are touched, respectively.
Specifically, when the capacitance processing module 19 detects that the capacitance change value generated when the first metal frame 21 detects that the first key 11 is touched is greater than or equal to a preset trigger threshold, the capacitance processing module sends a signal that the first key 11 is touched to the pressure detection module 18 through the first GPIO line, so as to trigger the pressure detection module 18 to detect the pressure value generated when the first key 11 is touched;
When the capacitance processing module 19 detects that the capacitance change value generated when the second metal frame 22 detects that the second key 12 is touched is greater than or equal to a preset trigger threshold, a signal that the second key 12 is touched is sent to the pressure detection module 18 through a second GPIO line, so that the pressure detection module 18 is triggered to detect the pressure value generated when the second key 12 is touched;

In addition, in order to facilitate the user to distinguish the first key 11, the second key 12 and the third key 13, the four insulation break points in the embodiment of the present invention may be designed to be different colors, so as to assist the user in visually positioning the three keys, thereby avoiding the user from touching by mistake.

It will be appreciated that the subject of execution of the method is a terminal device which is merely an exemplary illustration and should not be construed as limiting the method.
Fig. 5 is a schematic flowchart of a specific implementation of a method for detecting a touch key according to an embodiment of the present invention, where the method is applied to the terminal device described in fig. 1 to 4.
