[0029] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0031] On the one hand, combined with Figure 1 , 2 As shown, this embodiment provides a switch device 10 , which includes: a key cap member 1 , a press trigger element 2 and a touch trigger component 3 .

[0032] The press trigger element 2 is located inside the key cap component 1 , and the press trigger element 2 is configured to trigger a first switch signal when the key cap component 1 moves toward the press trigger element 2 .

[0033] The touch trigger component 3 is located inside or outside the keycap member 1. The touch trigger component 3 is configured to detect a touch action on the outside of the keycap member 1 and trigger a second switch signal when the touch action is detected. The outside of the keycap member 1 is the side with the interaction surface, that is, the side exposed to the outside and can be pressed and touched, and the inside of the keycap member 1 is the side opposite to the interaction surface, that is, the side not exposed to the outside.

[0034] The switch device 10 of this embodiment has a press trigger element 2 and a touch trigger component 3. When the keycap member 1 moves inward, the press trigger element 2 can be pressed, so that the press trigger switch sends a first switch signal. When there is a touch action on the surface of the keycap member 1, the touch trigger component 3 detects the presence of the touch action and sends a second switch signal, thereby giving the keycap member 1 two different operation modes, enriching the interaction form of the switch device 10, and enabling the electronic device to meet more complex operation requirements.

[0035] The key cap 1 is a physical object that the operator touches and clicks (presses), and has the function of transmitting the force and carrying the touch trigger component 3. The key cap 1 is usually made of plastic, and can also be made of various non-metallic and metal materials. The geometric shape and size of the key cap 1 can be freely designed according to product requirements.

[0036] In some possible implementations, the press trigger element 2 includes but is not limited to a tactile switch (TacticleSwitch), a micro switch (Micro Switch), etc., and has at least one movable part, and the element needs to perform a trigger action through the movement of the movable part.

[0037] Among them, the touch switch is a switch with obvious tactile feedback. When pressing or releasing the switch, the user can feel a clear click. The touch switch usually consists of a spring and a movable contact. When the switch is pressed, the contact will contact the fixed contact to complete the circuit switch. The micro switch is also called a micro switch or limit switch. It consists of a spring and a movable contact. When an external force acts on the switch, the contact will make instantaneous contact or separation, thereby realizing the switch of the circuit.

[0038] In some possible implementations, the touch trigger component 3 includes but is not limited to a membrane switch (MembraneSwitch), which is composed of multiple layers of thin film materials. Optionally, the membrane switch includes a conductive film layer, an isolation film layer, and an outer touch film layer. There are conductive contacts on the conductive film layer. When an external force acts on the outer touch film layer, the touch film will contact the conductive contacts, thereby forming a switch of the circuit.

[0039] Regarding the first switch signal and the second switch signal, optionally, the first switch signal and the second switch signal are current signals, voltage signals, resistance signals, pulse signals, or the like.

[0040] In addition, regarding the working principle of the touch trigger component 3, optionally, the touch trigger component 3 identifies the existence of a touch action by collecting capacitance values, voltage values, etc. when a touch activity occurs.

[0041] Combination Figure 1 ,2 As shown, in some embodiments, a supporting shaft 11 is provided on the inner side of the key cap member 1 , and the pressing trigger element 2 is located below the supporting shaft 11 .

[0042] By utilizing the support shaft 11 inside the key cap member 1 , when the key cap member 1 moves inward, the axial end of the support shaft 11 abuts against the press trigger element 2 , thereby achieving triggering of the press trigger element 2 .

[0043] Combination Figure 1 , 2 As shown, in some embodiments, the touch trigger component 3 includes a sensing element 31 and a touch sensing chip 32; at least a portion of the sensing element 31 is located on the inner side or the outer side of the keycap component 1, and the touch sensing chip 32 is electrically connected to the sensing element 31. The touch trigger component 3 is configured such that when the sensing element 31 detects a touch action on the surface of the keycap component 1, the touch sensing chip 32 triggers a second switch signal.

[0044] Among them, the touch key chip (Touch Sensor IC, Touch Key IC) is a conventional integrated circuit chip used to process and control the signal of the touch key. It usually includes functional modules such as touch detection, signal processing and communication interface. The touch key chip can detect the user's touch operation by sensing capacitance, resistance or pressure, and convert the touch signal into a digital signal (that is, the second switch signal) for output.

The touch key chip is a processing chip for monitoring and identifying capacitance changes. The two are interconnected through a circuit, and the induction coil becomes the sensing electrode of the touch key chip. When the finger (or skin) touches the keycap 1, the capacitance value of the induction coil will change, and the touch key chip will detect the corresponding change and output the corresponding first switch signal according to the preset logical judgment.

[0047] The induction coil as the induction element 31 can also utilize the axial expansion and contraction capability of the induction coil and be arranged on the inner side of the keycap member 1 . When the keycap member 1 moves inward, the induction coil is compressed and will not cause structural damage to itself, thereby helping to improve the reliability and service life of the induction element 31 .

[0051] The circuit board 4 in this embodiment can be used as a carrier of the press trigger element 2 and the touch sensing chip 32. The press trigger element 2 and the touch sensing chip 32 are connected to the circuit board 4 through a welding process, which helps to reduce the difficulty of assembling the press trigger element 2 and the touch sensing chip 32.

[0052] In some possible implementations, the circuit board 4 includes a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flexible board, and the like.

The conductive circuit 41 on the surface of the circuit board 4 is used to realize the electrical connection between the sensing element 31 and the touch sensing chip 32, which has a simple structure and is easy to assemble.

[0054] Optionally, a welding point is further provided on the surface of the circuit board 4 , and the welding point is located on the conductive circuit 41 . The sensing element 31 is welded and connected to the welding point, thereby realizing electrical connection between the sensing element 31 and the touch sensing chip 32 .

[0055] Combination Figure 1 , 2 As shown, in some embodiments, an accommodating groove 12 is provided on the inner side surface of the keycap member 1, and at least a portion of the sensing element 31 is located in the accommodating groove 12; the accommodating groove 12 is used to accommodate the sensing element 31, and the position of the sensing element 31 is fixed on the inner side surface of the keycap member 1 to prevent the sensing element 31 from falling off and shifting during the pressing and moving process of the keycap member 1.

[0056] Combination Figure 1 , 2As shown, in some embodiments, a step stopper 13 is provided on the outer side of the key cap member 1. The step stopper 13 is used to limit the key cap member 1 to be arranged in the key assembly hole.
