Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0061] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0062] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0063] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0064] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0065] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0066] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0067] The keys provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings. Figure 1 A schematic diagram of a key structure provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, an embodiment of the present application provides a key, which includes a key cap 10 , a first feedback member 30 and a second feedback member 60 .

[0068] The key cap 10 moves along the pressing direction when receiving the pressing operation of the pressing body;

[0069] The first feedback member 30 is in a first state based on the pressing pressure when the keycap 10 moves in the pressing direction and is within a first stroke. In the first stroke, the distance that the keycap 10 moves from the starting position in the pressing direction is a first distance.

[0070] In the first state, the first feedback member 30 generates a first feedback effect;

[0071] The second feedback member 60 is in a second state based on the pressing pressure when the keycap 10 moves in the pressing direction and is within the second stroke. In the second stroke, the keycap 10 moves a second distance from the starting position in the pressing direction, and the second distance is greater than the first distance.

[0072] In the second state, the second feedback member 60 generates a second feedback effect, which is different from the first feedback effect.

[0073] Optionally, the pressing body is used to apply a pressing operation to the keycap to achieve pressing of the key. The pressing body can be a user's finger or other pressing body, such as a pen. The pressing operation refers to the user's finger or other pressing body pressing down the keycap, which is arranged on the top of the key to receive the pressing operation of the user's finger.

[0074] When the keycap is pressed vertically downward by the user's finger, the keycap may move along the pressing direction, that is, the keycap may start to travel along the pressing direction.

[0075] The first stroke is the distance that the keycap 10 moves from the starting position along the pressing direction. The starting position may be the position of the keycap when the pressing pressure is 0, that is, the starting position or initial position of the keycap. Within the first stroke, the first feedback member is in the first state, which may be the first compression state or the first deformation state, etc. (see Figure 3a ), within the first stroke, the distance that the key cap 10 moves from the starting position along the pressing direction is the first distance. At this time, the first stroke can be equivalent to the first distance.

[0076] The second stroke is the distance that the key cap 10 moves along the pressing direction from the end position of the first stroke, and the end position may be the position where the key cap moves along the pressing direction to reach the maximum value of the first stroke. In the second stroke, the second feedback member is in a second state, which may be a second compression state or a second deformation state, etc. (see Figure 4a ), within the second stroke, the distance that the key cap 10 moves from the starting position along the pressing direction is the second distance, and the second distance is greater than the first distance. At this time, the total distance that the key cap 10 moves in the first stroke and the second stroke is the second distance.

[0077] The feedback effect in the embodiments of the present application may include any one or more of tactile feedback, auditory feedback, visual feedback, etc.

[0078] For tactile feedback, for example, the first feedback member and the second feedback member can be made of different materials, and their elastic parameters are very different. For example, the first feedback member can be made of a polymer material, and its elasticity is relatively soft and mild. The second feedback member can be made of a metal material, and its elasticity has a high degree of rigidity and toughness. The two feedback members of different materials are fed back to the pressing body through the keycap, so that the pressing body can have two different pressing sensations. In addition, the first feedback member can also feed back a first vibration through the keycap, and the second feedback member can feed back a second vibration. The first vibration and the second vibration are completely different vibrations, so that the pressing body has two different pressing sensations.

[0079] For auditory feedback, for example, the first feedback member can feedback a first sound through the keycap, and the second feedback member can feedback a second sound through the keycap, or the first feedback member and the second feedback member can feedback sounds of different sizes through the keycap, thereby generating two different feedbacks.

[0080] For visual feedback, for example, the first feedback member and the second feedback member feedback light effects of different colors through the keycap, and / or the first feedback member and the second feedback member feedback light effect patterns of different shapes through the keycap, etc.

[0081] In some application scenarios, for example, in a game scenario, (1) in the case of normal pressing, the pressing body presses the key downward, and the key cap moves along the pressing direction. When the key cap moves along the pressing direction and is within the first stroke, the first feedback member feedbacks red light. (2) in the case of gravity pressing, when the key cap continues to move along the pressing direction and is within the second stroke, the second feedback member feedbacks green light.

[0082] In other application scenarios, the feedback effect can be a combination of multiple different feedbacks. For example, the first feedback member can be made of polymer material, and the second feedback member can be made of metal material. (1) In the case of normal pressing, when the key cap moves along the pressing direction and is within the first stroke, the first feedback member feedbacks red light and generates the first vibration. (2) In the case of gravity pressing, when the key cap continues to move along the pressing direction and is within the second stroke, the second feedback member feedbacks green light and generates the second vibration, and so on.

[0083] In some other application scenarios, the first feedback effect and the second feedback effect may also be other feedback content that can be felt by the user, and this application does not make any special limitation.

[0084] The key provided in the embodiment of the present application generates two different feedback effects through two feedback members respectively when the user presses the key downward, thereby generating two different feedback sensations. The user can know the state of the key through the feedback sensation obtained, and then can choose to configure different trigger functions for different feedback sensations, so that more inputs of the combination key in the related art can be realized through one key, without the user having to operate with multiple fingers or multiple hands, thereby improving the user experience.

[0085] In some embodiments, the pressing pressure range required to move the keycap 10 a first distance may be a first pressure range, and when the pressing pressure of the pressing body received by the keycap reaches a maximum value of the first pressure range, the keycap may move along the pressing direction to reach a maximum value of the first stroke;

[0086] The pressing pressure range required to move the key cap 10 into the second stroke may be a second pressure range, and the maximum value of the first pressure range is less than the minimum value of the second pressure range;

[0087] Optionally, the first pressure range may be 0-75 g / f, and the second pressure range may be 75-300 g / f. Of course, the first pressure range may also be 0-80 g / f, and the second pressure range may be 80-300 g / f. The first pressure range may also be 0-180 g / f, and the second pressure range may be 180-300 g / f. The first pressure range and the second pressure range may be flexibly adjusted according to the actual situation of the key, and this application does not make any special restrictions.

[0088] In other embodiments, the pressing pressure range required to move the keycap 10 a first distance may be a first pressure range, and when the pressing pressure of the pressing body received by the keycap reaches a maximum value of the first pressure range, the keycap may move in the pressing direction to reach a maximum value of the first stroke;

[0089] The pressing pressure range required to move the keycap 10 into the second stroke may be the second pressure range, a third pressure range is provided between the first pressure range and the second pressure range, and any pressure value within the third pressure range is greater than zero.

[0090] Optionally, the first pressure range may be 0-75 g / f, the second pressure range may be 180-300 g / f, and the third pressure range may be 75-180 g / f. Of course, the first pressure range may also be 0-120 g / f, the second pressure range may be 180-300 g / f, and the third pressure range may be 120-180 g / f. The first pressure range, the second pressure range, and the third pressure range may be flexibly adjusted according to the actual situation of the key, and this application does not make any special restrictions.

[0091] In the above two embodiments, within the first stroke and the second stroke, the force changes with the stroke, and in some of the above embodiments, there is no pause between the first stroke and the second stroke from the first stroke to the second stroke. In other embodiments, there is a pause between the first stroke and the second stroke from the first stroke to the second stroke, and the user can feel a pause before having the second feedback feeling.

[0092] In some embodiments, the first feedback effect is fed back to the pressing body through the keycap 10, so that the pressing body has a first pressing feeling;

[0093] The second feedback effect is fed back to the pressing body through the key cap 10, so that the pressing body has a second pressing feeling, which is different from the first pressing feeling. The pressing feeling can be the touch and feedback when the user operates the key.

[0094] This embodiment generates two different feedback effects through two different feedback parts, and feeds back the two different feedback effects to the pressing body through the keycap, so that the user has two different pressing sensations. Two different trigger functions can be achieved through the two different pressing sensations. There is no need for the user to use multiple fingers or multiple hands, and there is no need for the user to accurately control the pressing force, thereby improving the accuracy of realizing different trigger functions by manually controlling the pressing force and enhancing the user experience.

[0095] In some embodiments, the second pressing sensation includes a first feedback effect and a second feedback effect.

[0096] For example, see Figure 2 , Figure 3a , Figure 3b , Figure 4a , Figure 4b and Figure 5 . Figure 2 is a schematic diagram of the button state when the pressing pressure is 0; Figure 3a A schematic diagram of a key state in which a first pressing feeling is generated and a first trigger signal is generated within a first stroke; Figure 3b is a schematic diagram of a force curve that generates a first pressing feeling within a first stroke; Figure 4a A schematic diagram of a key state in which a second pressing feeling is generated and a second trigger signal is generated within a second stroke; Figure 4b It is a schematic diagram of a force curve that generates a second pressing feeling within the second stroke. Figure 5 A schematic diagram of another force curve for generating a first pressing sensation and a second pressing sensation provided in an embodiment of the present application.

[0097] exist Figure 3b , Figure 4b and Figure 5 In the figure, the horizontal axis Strock represents the stroke, and the vertical axis Force represents the force.

[0098] In one possible embodiment, see Figure 2 When the pressing pressure is 0, the key state is the initial state, and neither the first feedback member nor the second feedback member is deformed.

[0099] See also Figure 3a and Figure 3b , within the first stroke (such as 0-1.5), the pressing body presses the keycap 10 downward, and the keycap 10 moves in the pressing direction. The distance that the keycap 10 moves from the starting position (0) in the pressing direction is the first distance (such as 1.5). The first feedback member 30 generates a first feedback effect based on the pressing pressure in the first state, so that the pressing body has a first pressing feeling; the first stroke (0-1.5) corresponds to the first pressure range (such as 0-180g / f).

[0100] See also Figure 4a and Figure 4b , within the second stroke (such as 1.5~1.8), the pressing body continues to press the keycap 10 downward, and the keycap 10 continues to move along the pressing direction. The distance that the keycap 10 moves from the starting position (0) along the pressing direction is the second distance (such as 1.8), and the first feedback element 30 generates a first feedback effect based on the pressing pressure in the first state and the second feedback element 60 generates a second feedback effect based on the pressing pressure in the second state, so that the pressing body has a second pressing feeling; the second stroke corresponds to a second pressure range (such as 180~300g / f).

[0101] The second distance (eg, 1.8) is greater than the first distance (eg, 1.5), and the maximum value of the first pressure range is less than the minimum value of the second pressure range. The starting position is the position of the keycap when the pressing pressure is 0.

[0102] In another possible embodiment, see Figure 5 , within the first stroke (such as 0-1.5), the pressing body presses the keycap 10 downward, and the keycap 10 moves in the pressing direction. The distance that the keycap 10 moves from the starting position (0) in the pressing direction is the first distance (such as 1.5). The first feedback member 30 generates a first feedback effect based on the pressing pressure in the first state, so that the pressing body has a first pressing feeling; the first stroke (0-1.5) corresponds to the first pressure range (such as 0-120g / f).

[0103] Continue to see Figure 5 , the pressing body continues to press the keycap 10 downward, and the keycap moves along the pressing direction to reach the maximum value of the first stroke, that is, the keycap reaches the end position of the first stroke along the pressing movement. At the end position of the first stroke and before entering the second stroke, the pressing body applies a pressing pressure of the third pressure range (such as 120-180g / f) to the keycap 10, but the keycap 10 is stationary at the maximum value of the first stroke, does not continue to move along the pressing direction, and does not travel. At this time, the user can feel a sense of pause. When the pressing pressure enters the second pressure range (such as 180-300g / f), it enters the second stroke.

[0104] In the second stroke (such as 1.5 to 1.8), the pressing body continues to press the keycap 10 downward, and the keycap 10 continues to move in the pressing direction. The distance that the keycap 10 moves from the starting position (0) in the pressing direction is the second distance (such as 1.8). The first feedback element 30 generates a first feedback effect based on the pressing pressure in the first state, and the second feedback element 60 generates a second feedback effect based on the pressing pressure in the second state, so that the pressing body has a second pressing feeling; the second stroke corresponds to the second pressure range (such as 180 to 300 g / f). A third pressure range (120 to 180 g / f) is provided between the first pressure range (such as 0 to 120 g / f) and the second pressure range (such as 180 to 300 g / f).

[0105] In some embodiments, the first feedback member 30 and the second feedback member 60 may both be elastic members, and the elastic materials of the first feedback member 30 and the second feedback member 60 may be different, so that the key generates two different pressing sensations.

[0106] The elastic member refers to an object that undergoes elastic deformation after being subjected to a force and returns to its original shape after the external force is removed. The material can be understood as the material, and the elastic materials of the elastic members of the first feedback member 30 and the second feedback member 60 are different.

[0107] The materials of the first feedback member 30 and the second feedback member 60 may be different, so that the elastic parameters of the first feedback member 30 and the second feedback member 60 are different. For example, the material of the first feedback member 30 may have a lower elastic modulus, while the material of the second feedback member 60 may have a higher elastic modulus. The elastic moduli of the first feedback member 30 and the second feedback member 60 are significantly different.

[0108] For example, the first feedback member 30 can be made of rubber material. Rubber is a polymer material with good elasticity and wear resistance. Its molecular structure enables it to withstand deformation and restore to its original state, and it also has the characteristics of anti-aging, acid and alkali resistance, cold and heat resistance, etc. Rubber has a small elastic modulus and a large elastic deformation.

[0109] The second feedback member 60 can be a micro switch, which is usually a switch that automatically restores its function after being pressed, also known as a limit switch or a touch switch, and its core structure includes a moving contact piece, a stationary contact piece, a driving component, a reset spring, and a housing. The spring is usually made of steel or alloy material and has a high elastic modulus. The spring restores energy through the elasticity of the material and exerts force and reaction force on the object.

[0110] It should be noted that the present application does not specifically limit the specific types of the first feedback member 30 and the second feedback member 60, that is, those skilled in the art can adjust their types according to actual conditions. The above situation is only an exemplary description of the specific types of the first feedback member 30 and the second feedback member 60 in the present application in what forms they can be applied, but is not limited to the situations described in the above embodiments.

[0111] The first feedback member 30 and the second feedback member 60 are objects that can undergo elastic deformation after being subjected to a force and return to their original shape after the external force is removed.

[0112] In some embodiments, the material of the first feedback member 30 may include a polymer material, which may be made of natural rubber or synthetic rubber, or may be compounded with other materials, and its elasticity is relatively soft and moderate. The material of the second feedback member 60 may include a metal material, such as steel, iron, copper or other metal materials or alloy materials, and its elasticity has high rigidity and toughness.

[0113] Exemplarily, the first feedback member 30 may include an elastic member such as an elastic rubber body, and the second feedback member 60 may include an elastic member such as a micro switch.

[0114] In some embodiments, within the first stroke, when the pressing pressure is greater than or equal to a first preset pressure, a first trigger signal is generated; the first preset pressure is within a first pressure range;

[0115] In the second stroke, when the pressing pressure is greater than or equal to the second preset pressure, a second trigger signal is generated; and the second preset pressure is within the second pressure range.

[0116] The generating of the first trigger signal and the second trigger signal in this embodiment may be understood as generating the first trigger signal and the second trigger signal, thereby triggering the first function and the second function of the key.

[0117] Exemplarily, there may be multiple ways to generate a trigger signal, for example, it may be triggered by a traditional method of switching on a circuit, it may be triggered by an optical keyboard, or it may be triggered by other methods, which are not limited in the present disclosure.

[0118] In a possible embodiment, the first pressure range is greater than 0 and not greater than 75 g / f, and the second pressure range is greater than 75 g / f and not greater than 300 g / f. The first preset pressure is 55 g / f, and the second preset pressure is 150 g / f.

[0119] In the first stroke, when the pressing pressure is between 0 and 55 g / f, the keycap travels a short distance. When the pressing pressure is between 55 and 75 g / f, the keycap continues to travel a short distance and generates or produces a first trigger signal. When the pressing pressure reaches 75 g / f, it enters the second stroke.

[0120] In the second stroke, when the pressing pressure is between 75 and 150 g / f, the keycap moves a short distance, and when the pressing pressure is between 150 and 300 g / f, the keycap continues to move a short distance and generates or produces a second trigger signal.

[0121] Exemplarily, within the first stroke, the pressing body presses the keycap downward, and the keycap moves along the pressing direction. When the pressing pressure reaches 55 g / f, a first trigger signal is generated or produced.

[0122] In the second stroke, the pressing body continues to press the keycap downward, and the keycap continues to move along the pressing direction. When the pressing pressure reaches 80g / f, 100g / f, and 120g / f, as long as it does not reach 150g / f, only the first trigger signal is generated or produced, and the second trigger signal is not generated; when the pressing pressure reaches 150g / f, the second trigger signal is generated or produced.

[0123] In another possible embodiment, the first pressure range is greater than 0 and not greater than 75 g / f; the third pressure range is greater than 75 g / f and not greater than 180 g / f; the second pressure range is greater than 180 g / f and not greater than 300 g / f. The first preset pressure is 55 g / f, and the second preset pressure is 200 g / f.

[0124] In the first stroke, when the pressing pressure is between 0 and 55 g / f, the key cap moves a short distance, and when the pressing pressure is between 55 and 75 g / f, the key cap continues to move a short distance, generating or producing the first trigger signal; when the pressing pressure is between 75 and 180 g / f, the stroke remains unchanged. When the pressing pressure reaches 180 g / f, it enters the second stroke.

[0125] In the second stroke, when the pressing pressure is between 180 and 200 g / f, the keycap moves a short distance, and when the pressing pressure is between 200 and 300 g / f, the keycap continues to move a short distance and generates or produces a second trigger signal.

[0126] Exemplarily, within the first stroke, the pressing body presses the keycap downward, and the keycap moves along the pressing direction. When the pressing pressure reaches 55 g / f, a first trigger signal is generated or produced.

[0127] Before entering the second stroke, the pressing body continues to press the keycap downward. Although the pressing pressure increases, the stroke remains unchanged, and the user will feel a pause.

[0128] In the second stroke, the pressing body continues to press the keycap downward, and the keycap continues to move along the pressing direction. When the pressing pressure reaches 200 g / f, a second trigger signal is generated or produced.

[0129] In some embodiments, see Figure 1 As shown, the key further includes a pair of scissors 20, which are arranged below the key cap.

At this time, the first circuit and the second circuit of the flexible circuit board 40 are conductive.

[0139] In some embodiments, see Figure 1 The second feedback member 60 may be disposed below the second flexible sub-circuit board 40, and the second feedback member 60 may include a switch device, which may be a mechanical switch such as a micro switch.
