[0028] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Figure 1 This is a schematic diagram of the structure of the keyboard key 10 provided in the embodiment of the present invention. Figure 1As shown, the keyboard keys 10 include:

[0030] Keycap 101, used to bear the key pressure;

[0031] A first trigger module 102 is disposed below the keycap 101 and is movably connected to the keycap 101 via a connecting assembly 103, and is configured to output a first key function when the key pressure borne by the keycap 101 is a first key pressure;

[0032] The second trigger module 104 is disposed below the first trigger module 102 and is in contact with the first trigger module 102 , and is configured to output a second key function when the key pressure borne by the keycap 101 is a second key pressure.

[0033] In the embodiment of the present invention, the keycap 101 is in the form of a keyboard key that is usually visible to the user. The user applies pressure to the keycap 101 by pressing the keycap 101. The first trigger module 102 is disposed below the keycap 101 and is movably connected to the keycap 101 through the connecting component 103. Figure 1 As shown, in this embodiment, the connecting component 103 is a scissor component. When the keycap 101 is pressed, the connecting component 103 will also produce a certain deformation, driving the first trigger module 102 to output the first key function under the (first) key pressure. The second trigger module 104 is arranged below the first trigger module 102 and is in contact with the first trigger module 102. When the key pressure borne by the keycap 101 is the second key pressure, the second trigger module 104 is used to output the second key function. The first key pressure is different from the second key pressure, and the first key function is different from the second key function.

[0034] The keyboard key of the present invention includes: a keycap for bearing key pressure; a first trigger module disposed below the keycap and movably connected to the keycap via a connecting assembly, for outputting a first key function when the key pressure borne by the keycap is a first key pressure; and a second trigger module disposed below the first trigger module and in contact with the first trigger module, for outputting a second key function when the key pressure borne by the keycap is a second key pressure. The present invention enables a single key to output two different functions by using two different pressing forces, turning a single key input into a dual input, greatly improving work efficiency.

[0035] In one embodiment, the first trigger module 102 includes a rubber button 1021, a first silver paste circuit film 1022 and a first support plate 1023; the rubber button 1021, the first silver paste circuit film 1022 and the first support plate 1023 are contacted and connected in sequence, the first end of the connecting component 103 is connected to the first silver paste circuit film 1022 through a connecting buckle, and the second end of the connecting component 103 is connected to the keycap 101 through a connecting buckle.

[0036] In this embodiment, reference Figure 1 As shown, the first trigger module 102 includes a rubber button 1021, a first silver paste circuit film 1022 and a first support plate 1023. The rubber button 1021, the first silver paste circuit film 1022 and the first support plate 1023 are contacted and connected in sequence. The first end of the connecting component 103 is connected to the first silver paste circuit film 1022 through a connecting buckle, and the second end of the connecting component 103 is connected to the keycap 101 through a connecting buckle, thereby realizing the connection between the keycap 101 and the first trigger module 102.

[0037] In one embodiment, the rubber key 1021 is used to transmit the first key pressure carried by the keycap 101 to the first silver paste circuit film 1022;

[0038] The first silver paste circuit film 1022 is used to conduct the circuit under the first key pressure transmitted by the rubber key 1021 to generate a signal to output the first key function;

[0039] The first support plate 1023 is used to support the first silver paste circuit film 1022 to ensure that the first silver paste circuit film 1022 is placed stably.

[0040] In this embodiment, the first silver paste circuit film 1022 is a flexible and very thin film, which requires the support of the first support plate 1023 to ensure that the first silver paste circuit film 1022 is placed stably. When the user presses the keycap 101 with the first key pressure, the keycap 101 will move downward under the action of the force. In the process of the keycap 101 moving downward, the rubber key 1021 below is subjected to force, and then compressed and deformed downward. In the process of the rubber key 1021 being pressed downward and deformed, the first silver paste circuit film 1022 below is subjected to force to make the circuit conductive, generate a conductive signal and send it to the EC (Embedded Controller) of the laptop computer, and the EC determines the function (first key) corresponding to this conductive signal and outputs it.

[0041] In one embodiment, the second trigger module 104 includes a metal button 1041 , a second silver paste circuit film 1042 , and a second support plate 1043 ; the metal button 1041 , the second silver paste circuit film 1042 , and the second support plate 1043 are sequentially contacted and connected.

[0042] In this embodiment, reference Figure 1 As shown, the second trigger module 104 includes a metal key 1041, a second silver paste circuit film 1042 and a second support plate 1043, and the metal key 1041, the second silver paste circuit film 1042 and the second support plate 1043 are in contact and connected in sequence. It can be understood that the reason why the second trigger module 104 is provided with a metal key 1041 and the first trigger module 102 is provided with a rubber key 1021 is because the metal key 1041 and the rubber key 1021 have obvious differences in the pressing feel due to their different materials, and the force required for conduction is also different, so they can be clearly distinguished when pressed. In the prior art, keyboard keys usually only include the aforementioned keycap 101 and the first trigger module 102. The present invention changes the longitudinal structure of the keyboard keys without changing the existing keyboard layout, that is, adds the second trigger module 104, which can realize the input of two different functions by using two different pressing forces on one key.

[0043] In one embodiment, the metal key 1041 is used to transmit the second key pressure carried by the keycap 101 to the second silver paste circuit film 1042;

[0044] The second silver paste circuit film 1042 is used to conduct the circuit under the second key pressure transmitted by the metal key 1041 to generate a signal to output the second key function;

[0045] The second supporting plate 1043 is used to support the second silver paste circuit film 1042 to ensure that the second silver paste circuit film 1042 is placed stably.

[0046] In this embodiment, the second silver paste circuit film 1042 is a flexible and very thin film that requires support from a second support plate 1043 to ensure that the second silver paste circuit film 1042 is placed stably. When a user presses the keycap 101 with the second key pressure, the keycap 101 moves downward under the action of the force. During the downward movement of the keycap 101, the rubber key 1021 and the metal key 1041 below are both subjected to force. The metal key 1041 transmits the second key pressure carried by the keycap 101 to the second silver paste circuit film 1042 below, causing the second silver paste circuit film 1042 below to be subjected to force, thereby conducting the circuit and generating a conduction signal that is sent to the laptop's EC. The EC then determines the function (of the second key) corresponding to this conduction signal and outputs it.

[0047] In one embodiment, the first silver paste circuit film 1022 includes a first silver paste top layer 10221, a first insulating layer 10222, and a first silver paste bottom layer 10223, and the first silver paste top layer 10221, the first insulating layer 10222, and the first silver paste bottom layer 10223 are sequentially contacted and connected;

[0048] The first silver paste top layer 10221 is used to contact the first silver paste bottom layer 10223 under the first key pressure transmitted by the rubber key 1021 to form a loop to conduct the circuit;

[0049] The first insulating layer 10222 is used to isolate the first silver paste top layer 10221 and the first silver paste bottom layer 10223 when the rubber key 1021 is not subjected to the pressure of the first key.

[0050] refer to Figure 2 As shown, the first silver paste circuit film 1022 includes a first silver paste top layer 10221, a first insulating layer 10222 and a first silver paste bottom layer 10223. The first silver paste top layer 10221, the first insulating layer 10222 and the first silver paste bottom layer 10223 are in contact and connected in sequence. The first silver paste top layer 10221 and the first silver paste bottom layer 10223 both include silver paste lines. When the rubber button 1021 is not subjected to the first button pressure (i.e., when Figure 2 When the value of F is 0), the first insulating layer 10222 isolates the first silver paste top layer 10221 and the first silver paste bottom layer 10223, so that the first silver paste top layer 10221 and the first silver paste bottom layer 10223 do not contact each other, and thus no loop is formed to conduct the circuit. Figure 2 When the value of F is the first key pressure, the first silver paste top layer 10221 contacts the first silver paste bottom layer 10223 under the action of pressure to form a loop to conduct the circuit.

[0051] In one embodiment, the second silver paste circuit film 1042 includes a second silver paste top layer 10421, a second insulating layer 10422, and a second silver paste bottom layer 10423, and the second silver paste top layer 10421, the second insulating layer 10422, and the second silver paste bottom layer 10423 are in contact with each other in sequence;

[0052] The second silver paste top layer 10421 is used to contact the second silver paste bottom layer 10423 under the second key pressure transmitted by the metal key 1041 to form a loop to conduct the circuit;

[0053] The second insulating layer 10422 is used to isolate the second silver paste top layer 10421 and the second silver paste bottom layer 10423 when the metal key 1041 is not subjected to the pressure of the second key.

[0054] refer to Figure 2As shown, the second silver paste circuit film 1042 includes a second silver paste top layer 10421, a second insulating layer 10422, and a second silver paste bottom layer 10423. The second silver paste top layer 10421, the second insulating layer 10422, and the second silver paste bottom layer 10423 are in contact and connected in sequence. The second silver paste top layer 10421 and the second silver paste bottom layer 10423 both include silver paste lines. When the metal key 1041 is not subjected to the second key pressure (i.e., when Figure 2 When the value of F is 0), the second insulating layer 10422 isolates the second silver paste top layer 10421 and the second silver paste bottom layer 10423, so that the second silver paste top layer 10421 and the second silver paste bottom layer 10423 do not contact each other, and thus no loop is formed to conduct the circuit. Figure 2 When the value of F is the second key pressure, the second silver paste top layer 10421 contacts the second silver paste bottom layer 10423 under the action of pressure to form a loop to conduct the circuit.

[0055] In one embodiment, the first key pressure is smaller than the second key pressure.

[0056] In this embodiment, the first key pressure is 100g and the second key pressure is 150g. The first key pressure is less than the second key pressure, so that the function of the key trigger point on the keyboard can be triggered according to the pressure strength, and the two functions of one key can be switched freely.

[0057] In one embodiment, the keyboard key 10 further includes a backlight module 105 , which is disposed below the second trigger module 104 and in contact with the second trigger module 104 , for providing backlight for the keyboard key 10 to illuminate the keyboard.

[0058] In this embodiment, reference Figure 1 As shown, the keyboard keys 10 further include a backlight module 105. The backlight module 105 is disposed below the second trigger module 104 and is in contact with the second trigger module 104 to provide backlight for the keyboard keys 10 to illuminate the keyboard. This can provide backlight for the keyboard even when the user is in a low-light environment (e.g., in the evening), making it easier for the user to use the keyboard.

[0059] Figure 3 This is a schematic diagram of the structure of a keyboard 11 provided in an embodiment of the present invention. The keyboard 11 includes the keyboard keys 10 as described above.

[0060] In the embodiment of the present application, the keyboard 11 is composed of the following components: Figure 3As shown, the keyboard 11 includes keyboard keys 10, which enable the keyboard 11 to implement a single-key dual-input function without changing the key layout. For example, in a computer game, the character's movement direction is usually controlled by the four keys W / S / A / D. The keyboard 11 of the embodiment of the present application can move the character in a specified direction at a normal speed by pressing the four keys with normal force, and move the character in a specified direction at a faster speed by pressing the four keys with gravity, etc. This improves the practicality and convenience of the keyboard.
