A gap may be left between the skirt 313 and the lower surface of the panel 102, so that when the user presses one end of the button device 200, the other end can be tilted, thereby preventing the button device 200 from being stuck or the skirt 313 frequently touching the panel 102. Lower surface, causing wear. In other embodiments, the touch component may not interfere with the switch 1 and only need to be able to conduct the pressure of the pressing to the switch 1 when pressing, for example, a component that provides a conductive force between the touch component and the switch.

In some embodiments of the present invention, from the perspective of the working principle, as shown in FIG. 8, the button device 200 further includes a processor 4, and the processor 4 cooperates with the switch 1 and the touch component 3 to implement corresponding functions. The touch component 3 is configured to output a touch signal according to the touch action, the switch 1 is configured to output a press signal according to the pressing action, and the processor 4 is communicably connected with the touch component 3 and the switch 1 and outputs the touch signal. Or press the control command corresponding to the signal. In some embodiments, the manipulation method of the button device includes steps S1 to S3. S1: The processor 4 determines whether a pressing signal is generated on the switch 1, and if so, executes S3. If not, executes step S2; S2: the processor 4 determines whether the touch component 3 generates a touch signal, and if so, outputs The first control command, if not, is not output; S3: outputting the second control command. Preferably, the control instruction includes a first control instruction and a second control instruction.

The processor 4 includes a first output module 41, a second output module 42, and a selection control module 43 as shown in FIG. It can be understood that the processor 4 can be a device separately provided for the button device 200, or can be a portion originally belonging to the terminal but shared with the button device 200.

The first output module 41 is configured to output a first control instruction according to the touch signal. As an option, first The output module 41 is further configured to search whether there is corresponding valid data in the register database according to the touch signal, and output the first control instruction when the corresponding valid data is found. Preferably, the first output module 41 reads data of the relevant registers in the control chip through the IIC bus.

The second output module 42 is configured to output a second control instruction according to the pressing signal. Alternatively, the first control command and/or the second control command are at least one of an exit key command, a return key command, a sleep wake-up command, and an exit command. Preferably, the first control instruction and the second control instruction are respectively a HOME key instruction or a BACK key instruction. For example, the first control command is a return key command and the second control command is an exit command. It can be understood that the exit instruction is an instruction that the terminal returns to the system desktop.

The selection control module 43 is connected to the first output module 41 and the second output module 42 for selecting the first output module 41 to output the first control command or the second output module 42 to output the second control command according to the pressing signal. Preferably, when the switch 1 does not have any pressing or the pressing pressure is less than the pressing threshold, the processor 4 detects that the voltage of the switch 1 is high level (the voltage value is equivalent to VDD/AVDD); when the finger corresponding to the pressing signal or When the pressure of other objects pressed to the switch 1 reaches or exceeds the pressing threshold, the processor 4 detects that the voltage of the switch 1 is low (short-circuited with GND). It can be understood that the pressing pressure threshold is 1.6-3.5N. Preferably, the pressing pressure threshold is 2.4N. When the processor 4 detects that the voltage of the switch 1 is high, the processor 4 considers that the switch 1 is not pressed, and detects the signal of the touch sensor 32. When the processor 4 detects that the voltage of the switch 1 is low, the processor 4 ignores the signal of the touch sensor 32 at this time, and considers that the switch 1 is in the pressed state.

Preferably, some embodiments may also include a method of preventing false touches. Before step S1, the method further includes the following steps: the processor 4 determines whether the switch 1 generates a touch sensing signal according to an external touch action, and if so, the generation of the pressing signal is based on an instruction issued by the user, thereby Step S1 can be continued. If not, it means that the command is not issued by the user, but the pressing signal is generated due to accidental contact with other objects. In this case, the subsequent operation is immediately ended. This has the advantage that the pressing signal can be further judged only after the user issues an instruction, and if the other object is accidentally touched, the current operation interface is directly exited, thereby preventing the user from influencing the experience by accidentally touching the switch 1.

In some preferred embodiments, the manipulation method further includes the following steps T1 to T3. T1: The selection control module 43 determines whether a pressing signal is generated on the switch 1, and if so, executes step T3; if not, executes step T2. T2: The selection control module 43 selects the first output module 41 to output the first control instruction. T3: The selection control module 43 selects the second output module 42 to output the second control instruction.

As shown in FIG. 10 , the touch sensor 32 includes a touch sensing module 321 and a touch determining module 322 . The touch sensing module 321 is configured to sense a touch action and output an inductive signal. As shown in FIG. 11 to FIG. 14 , the touch sensing module 321 includes a driving unit 321A, a sensing unit 321B, and an analyzing unit 321C. The driving unit 321A and the sensing unit 321B are formed to change according to changes in the touch motion. The variable capacitance, the analyzing unit 321C outputs the sensing signal according to the variable capacitance. Preferably, the preset threshold is a preset capacitance threshold, and the preset threshold may be adjusted according to actual needs. The touch sensing module 321 is composed of two sides, and the front surface is a driving unit 321A and a sensing unit 321B, which are embedded and staggered with each other, and the reverse side is a copper covering of GND. Preferably, the driving unit 321A and the sensing unit 321B are both comb-shaped structures, and the comb-tooth portions of the two are interlaced and arranged, and are interchangeable. Alternatively, the front side is the drive unit 321A and the sensing unit 321B may have other configurations as long as the interlace embedding setting can be realized. The base ring 312 can be connected to GND to improve the electrostatic shielding performance. When no substance is in contact with the touch sensor 32, a capacitance is formed between the electrodes of the driving unit 321A and the sensing unit 321B. When lightly touching or pressing the surface of the button with a finger or other conductive material is less than a pressure threshold, it will cause The capacitance between the driving unit 321A and the sensing unit 321B changes. As can be appreciated, the pressure threshold is between 1.6 and 3.5N. Preferably, the pressure threshold is 2.4N. The size of the pressure threshold can be determined according to the model of switch 1 (switch 1 can select the pot switch). Different switch pressure thresholds are different, and can be selected according to actual needs. When the capacitance change reaches and exceeds a preset capacitance value change, the analyzing unit 321C generates an interrupt information, and outputs an induction signal, and the sensing signal includes the interrupt information.

The touch determination module 322 is configured to determine whether the sensing signal reaches a predetermined threshold, and output the touch signal when the signal is reached. It can be understood that the first output module 41 is connected to the touch determination module 322 and outputs a first control instruction according to the received touch signal.

Preferably, in some embodiments, the above steps S2 further include the following steps P1 to P3. P1: The touch sensing module 321 senses the touch action and outputs the sensing signal, and the sensing signal includes the interrupt information. Alternatively, the first output module 41 determines whether there is corresponding valid data in the register database according to the touch signal, and if so, outputs the first control command, and if not, does not output. P2: The touch determination module 322 determines whether the sensing signal reaches a preset threshold, and if so, performs step P3; if not, ends. P3: The first output module 41 outputs a first control instruction.

The material of the base 31 is a metal material to increase the structural strength. The base 31 may be integrally formed, for example, by stamping to facilitate forming. When the susceptor 31 is made of a metal material, in order to avoid electrostatic interference to the touch sensor 32, the susceptor 31 and the touch sensor 32 need to be electrically connected, so that the touch sensor 32 is adhered by the second fixed double-sided tape 36. In the pedestal 31, the second fixed double-sided tape 36 is a conductive double-sided tape, the touch sensor 32 is connected with a flexible circuit board (FPC) 34, and the flexible circuit board 34 is provided with a metal contact 341 (gold finger), a flexible circuit The plate 34 extends from the base 31 and is in contact with the metal dome 342 on the main board 104 via the metal contacts 341. Connected to the main board 104 through the flexible circuit board 34 of the touch sensor 32, the base 31 is grounded through the main board 104, of course, In other embodiments, the susceptor 31 may not be grounded.

One end of the touch sensor 32 is connected with a flexible circuit board 34, and the flexible circuit board 34 has an opening 310. And the notch 310a protrudes from the base 31. Through the opening 310 and the notch 310a, the flexible circuit board 34 can be conveniently disposed to electrically connect the touch sensor 32 to the main board 104. The use of the notch 310a can avoid interference between the flexible circuit board 34 and the support member 2.

Here, in other embodiments, the flexible circuit board 34 can also be conveniently disposed by providing an opening in the base ring 312.

The switch 1 is used for the user's pressing input. When the user presses the button device 200, the touch component 3 moves toward the proximity switch 1 under the pressure of the user, and the switch 1 is triggered.

Here, in other embodiments, the switch 1 can also be disposed on the first internal structural support 103 or other component within the terminal.

The switch 1 is preferably a membrane button device. In other embodiments, the switch may also be a other type of switch button device such as a patch type tact switch or a conductive rubber switch. By using the switch and the touch component 3, the button device has mechanical buttons and touch functions at the same time, and the user's touch and push operation can provide two different electrical signals, thereby realizing various control functions on one component. When the user presses the button device, the touch sensing signal and the switch 1 can be triggered at the same time, thereby realizing various control functions on one component and saving the structure space. The two control signals generated by the touch sensor 32 and the switch 1 can be used to control different functions respectively, and can also control the same function at the same time, for example, when two When a control signal is generated at the same time, a certain function is activated, so that the false touch can be effectively avoided.

The support member 2 is a silicone seat, so that it has a certain deformation property and is supported under the touch component 3. When the touch component 3 moves toward the switch 1, the support member 2 can be deformed to enable the touch component 3 to move downward.

When the support 2 is in a deformed state under the pressing of the touch component 3, the bump 314 abuts against the switch 1 to trigger the switch 1. Since the bump 314 is formed by the base 31, the bump 314 is a part of the base 31 and is also made of metal, which has a certain hardness to facilitate the pressure against the switch 1 and the switch 1. In this embodiment, the switch 1 is a membrane button device, and when the pot is pressed by the bump 314, the switch 1 can be triggered and the user can be provided with press feedback, thereby generating a pressing signal, and the pressing signal is transmitted to the selection control module 43.

The touch component 3 is supported above the switch 1 by the support member 2 to facilitate the triggering of the switch 1. The base 31 of the touch component 3 can be fixed to the support 2 by glue, so that the touch component 3 and the support 2 are integrally connected, and the touch component 3 is positioned through the mounting hole 110 while the first internal structure The support member 103 is pressed against the support member 2, so that the fixed connection structure is not required between the support member 2 and the main board 104, so that the support member 2 can directly abut against the main board 104, thereby facilitating the assembly connection.
