Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular, to a key, a sensor, a method for key input, and a keyboard. Background Art

[0002] The QWERTY keyboard we use was patented as early as 1868. And the Shift key has existed even before the invention of the QWERTY keyboard. This design of using a combination key to increase the function of a key has remained unchanged for two hundred years.

[0003] Combination keys are commonly known as shortcut keys, also called quick keys or hot keys, which refer to completing an operation through certain specific keys, key sequences, or key combinations. Many shortcut keys are often used in combination with keys such as the Ctrl key, Shift key, Alt key, Fn key, as well as the Windows key on the Windows platform and the Meta key on Mac machines. Using shortcut keys can replace the mouse to do some work, and can be used to open, close, and navigate the "Start" menu, desktop, menu, dialog box, and web page. Shortcut keys can also be used in Word.

[0004] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0005] When using combination keys, two fingers are required. First, the function key is triggered, and then the normal key is triggered. Moreover, in many cases, it is difficult to press (due to the relatively long distance between the two keys). For example, Ctrl+Y often disrupts the normal typing gesture.

[0006] Therefore, how to improve the operation method of combination keys to make them convenient to use is a technical problem to be solved urgently. Summary of the Invention

[0007] In view of this, embodiments of the present invention provide a key, a sensor, a method for key input, and a keyboard, which can solve the problem that the operation method of combination keys in the prior art is not convenient to use.

Among them, the first sensing piece first contacts the third sensing piece, and then the second sensing piece contacts the fourth sensing piece, thereby triggering the first key function of the first sensor.

[0014] After the second sensing piece contacts the fourth sensing piece, the second key function of the first sensor is triggered.

[0015] To achieve the above object, according to another aspect of the embodiments of the present invention, a sensor is provided.

[0016] A sensor according to an embodiment of the present invention includes a first sensor and a second sensor; the first sensor at least includes a first sensing piece and a second sensing piece; the second sensor at least includes a third sensing piece and a fourth sensing piece; wherein: when the first sensing piece contacts the third sensing piece, the first key function of the first sensor is triggered; when both the first sensing piece contacts the third sensing piece and the second sensing piece contacts the fourth sensing piece, the second key function of the first sensor is triggered.

[0017] To achieve the above object, according to still another aspect of the embodiments of the present invention, a key input method is provided.

[0018] A key input method according to an embodiment of the present invention is applied to a key including a keycap, a key switch, a first return spring, a second return spring, a first sensor, and a second sensor. The first sensor is located on the side of the keycap. The method includes the following steps: after the keycap is pushed by an external force, it drives the key switch to tilt towards the second sensor, so that the first sensor contacts the second sensor, triggering the corresponding key function of the first sensor; the first return spring and the second return spring drive the key switch to return to the stationary state, so that the first sensor is separated from the second sensor to complete the key input.

[0019] In an embodiment of the present invention, the first sensor includes at least a first sensing piece and a second sensing piece; the second sensor includes at least a third sensing piece and a fourth sensing piece; and it is characterized in that, after the keycap is pushed by an external force, the key switch is driven to incline towards the second sensor, so that the first sensor contacts the second sensor, triggering the corresponding key function of the first sensor, including: when the keycap is pushed by an external force and drives the key switch to incline towards the third sensing piece and the fourth sensing piece, the first sensing piece contacts the third sensing piece to trigger the first key function of the first sensor; then, the second sensing piece contacts the fourth sensing piece to trigger the second key function of the first sensor.

[0040] The following describes exemplary embodiments of the present invention with reference to the accompanying drawings. Various details of the embodiments of the present invention are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well - known functions and structures are omitted below.

[0041] Figure 1 Is a perspective view of one direction of the key in a static state according to an embodiment of the present invention. As Figure 1 shown, from bottom to top are the bottom plate 1, the key switch 2, and the keycap 3 in sequence. Among them, a second sensor 5 is further provided on the bottom plate 1, and a first sensor 4 is further provided on the key switch 2. Specifically, the settings in the embodiments of the present invention are as follows:

[0042] The key switch 2 can move between a pressed position and a released position relative to the base plate 1; the keycap 3 is arranged on the other side of the key switch 2 relative to the base plate 1; the first sensor 4 is arranged on the side surface of the key switch 2 perpendicular to the base plate 1; the second sensor 5 is vertically arranged on the base plate 1 and on the same side as the first sensor 4. Among them, when the keycap 3 is pushed by an external force, it drives the key switch 2 to tilt and leave the released position, and after the first sensor 4 contacts the second sensor 5, the key function corresponding to the first sensor 4 is triggered. Through the setting mode of the embodiment of the present invention, after being pushed by an external force, the key is tilted, and the first sensor 4 contacts the second sensor 5 to achieve the purpose of triggering the corresponding key function.

[0043] For the purpose of fixation, in an embodiment of the embodiment of the present invention, a fixed base 7 is arranged on the base plate 1, and a fixed bracket 8 is arranged in the key switch 2. Among them, one side of the fixed base 7 is rotatably connected to the fixed bracket 8, and the key switch 2 can slide along the fixed bracket 8. Specifically, the fixed base 7 is fixed on the base plate 1, and one side of the fixed bracket 8 is rotatably connected to one surface of the fixed base 7 (the specific connection method can be a shaft connection or an elastic plastic connection, etc., and is not limited by the embodiment of the present invention as long as a fixed rotatable connection can be achieved), and at the same time, the key switch 2 and the fixed bracket 8 are connected in a matching manner, so that the entire key switch 2 is fixed on the base plate 1.

[0044] Figure 2 It is a perspective view of the other direction of the key in the static state according to the embodiment of the present invention, as Figure 2 shown, a connecting block 10 is further arranged on the key switch 2, and a connecting groove 11 is further arranged on the keycap 3. The connecting groove 11 and the connecting block 10 are connected together to realize the detachable fixation of the keycap 3 on the key switch 2.

[0045] Figure 3 It is a side perspective view of the key in the tilted state under the action of an external force according to the embodiment of the present invention, as Figure 3 shown, the key is tilted under the action of an external force. At this time, the first sensor 4 contacts the second sensor 5, thereby triggering the key function corresponding to the first sensor 4. Since the fixed bracket 8 is rotatably connected to the fixed base 7, the key only rotates and tilts on the fixed base 7 relative to the base plate 1 along this connecting edge and does not move or shift to other positions.

[0046] Similarly, in order to enable the key switch 2 to resume its state after the external force is released, in an embodiment of the present invention, a first return spring 6 is provided between the bottom plate 1 and the fixed bracket 8, which is used to make the surface of the fixed bracket 8 relative to the bottom plate 1 contact and reset with the fixed base 7. Since one side of the fixed bracket 8 is rotatably connected to the fixed base 7 and the other side is connected to the first return spring 6, therefore, under the action of the first return spring 6, the fixed bracket 8 is restored to the static state, that is, the surface of the fixed bracket 8 relative to the bottom plate 1 contacts the surface of the fixed base 7.

[0047] It should be noted that the first sensor 4 at least includes a first sensing piece 4.1 and a second sensing piece 4.2, and the second sensor 5 at least includes a third sensing piece 5.1 and a fourth sensing piece 5.2. Among them, the first sensing piece 4.1 contacts the third sensing piece 5.1 first, and then the second sensing piece 4.2 contacts the fourth sensing piece 5.2, thereby triggering the first key function of the first sensor 4. Specifically, Figure 1 and Figure 2 it can be seen that the first sensing piece 4.1 is at a lower distance from the bottom plate 1 than the second sensing piece 4.2, but at a greater distance from the key switch 2 (that is, the first sensing piece 4.1 is closer to the third sensing piece 5.1), and the third sensing piece 5.1 and the fourth sensing piece 5.2 are arranged in the same way relative to the bottom plate 1. That is to say, when the key is pushed obliquely under the action of an external force, since the first sensing piece 4.1 is closer to the third sensing piece 5.1, the first sensing piece 4.1 contacts the third sensing piece 5.1 first, and then the second sensing piece 4.2 contacts the fourth sensing piece 5.2. In a specific usage scenario, the first sensing piece 4.1 can be represented as a function key, such as Shift, Ctrl, etc., and the second sensing piece 4.2 can be represented as a normal key, such as A, Q, etc. When the first sensing piece 4.1 contacts the third sensing piece 5.1, the function key function is triggered; when the second sensing piece 4.2 contacts the fourth sensing piece 5.2, the normal key function is triggered. Therefore, when the first sensing piece 4.1 contacts the third sensing piece 5.1 first and then the second sensing piece 4.2 contacts the fourth sensing piece 5.2, it means that the function key function is triggered first and then the normal key function is triggered, that is, the combination key function (that is, the above-mentioned first key function), such as Shift+A, Shift+Q, etc. The usage scenario of the embodiment of the present invention is as Figure 4As shown, it is a perspective view of the contact state of the key pushing and tilting the inductor under an external force according to an embodiment of the present invention. The third sensing sheet 5.1 and the fourth sensing sheet 5.2 have the same height and width; the second sensing sheet 4.2 is slightly higher than the first sensing sheet 4.1 as a whole; the first sensing sheet 4.1 has a protrusion 4.3 and a closed tail 4.4, and the second sensing sheet 4.2 has a protrusion 4.5 and an open tail 4.6. Among them, the vertical distance between the protrusion 4.5 of the second sensing sheet 4.2 and the third sensing sheet 5.1 is less than or equal to zero, and the vertical distance between the open tail 4.6 and the fourth sensing sheet 5.2 is farther than the vertical distance between the protrusion 4.3 and the third sensing sheet 5.1. Therefore, during the process of the key being pushed and tilted by an external force, it is the protrusion 4.3 of the first sensing sheet 4.1 that first contacts the third sensing sheet 5.1, and then it is the open tail 4.6 of the second sensing sheet 4.2 that contacts the fourth sensing sheet 5.2.

[0048] It should also be noted that in some other embodiments, the first sensing sheet 4.1 and the second sensing sheet 4.2 can have the same height, and only need to have different distances from the key switch 2 (for example, the first sensing sheet 4.1 is farther from the key switch 2 than the second sensing sheet 4.2 as described above). Of course, there can also be other setting methods, as long as the condition that the first sensing sheet 4.1 contacts first and the second sensing sheet 4.2 contacts later can be satisfied. Therefore, other setting methods are also within the protection scope of the embodiments of the present invention.

[0049] Figure 5 It is a side perspective view of the key in a tilted and pressed state under an external force according to an embodiment of the present invention. As Figure 5 shown, the key is not only tilted by the external force but also pressed by the external force. At this time, since the first sensing sheet 4.1 contacts the third sensing sheet 5.1 first, and then the second sensing sheet 4.2 contacts the fourth sensing sheet 5.2, the first key function is triggered. Although the key is pressed, the contact method and the sequence of the first inductor 4 and the second inductor 5 do not change, so the final trigger result will not be changed.

[0050] It should be noted that in order to make the key switch 2 return after the external force is released, in an embodiment of the present invention, a second return spring 9 is provided on the other side of the fixed bracket 8 relative to the bottom plate 1 for sliding the key switch 2 to the release position for resetting. As Figure 5 shown in the usage scenario, the second return spring 9 is compressed under the external force. At this time, the second return spring 9 contains a restoring force. When the external force is released, under the action of the second return spring 9, the key switch 2 will slide from the pressed position along the fixed bracket 8 to the release position.

[0051] Figure 6is a side perspective view of the key in the depressed state under an external force according to an embodiment of the present invention, as Figure 4 and Figure 6 shown, the key is depressed under the action of an external force. Since the second sensing piece 4.2 is at a greater distance from the bottom plate 1 than the first sensing piece 4.1, and the vertical distance between the protrusion 4.5 of the second sensing piece 4.2 and the fourth sensing piece 5.2 is less than or equal to zero, during the depression process, it is the protrusion 4.5 of the second sensing piece 4.2 that contacts the fourth sensing piece 5.2, and the first sensing piece 4.1 does not contact the third sensing piece 5.1 throughout the process. In the embodiment of the present invention, after the second sensing piece 4.2 contacts the fourth sensing piece 5.2, the second key function of the first sensor 4 is triggered, that is, only the ordinary key function of the second sensing piece 4.2 is triggered, for example, only A or only Q is triggered.

[0052] Similarly, the second return spring 9 is compressed under the action of an external force. At this time, the second return spring 9 contains a restoring force. When the external force is released, under the action of the second return spring 9, the key switch 2 slides from the pressed position along the fixed bracket 8 to the released position.

[0053] In addition, the embodiment of the present invention also provides a sensor, which includes a first sensor 4 and a second sensor 5. Among them, the first sensor 4 at least includes a first sensing piece 41 and a second sensing piece 42, and the first sensing piece 41 and the second sensing piece 42 can be arranged on the side surface of the key switch 2 perpendicular to the bottom plate 1. The second sensor 5 at least includes a third sensing piece 51 and a fourth sensing piece 52, and the third sensing piece 51 and the fourth sensing piece 52 are vertically arranged on the bottom plate 1 and on the same side as the first sensor 4.

[0054] When the first sensing piece 41 contacts the third sensing piece 51, the first key function of the first sensor 4 is triggered. When both the first sensing piece 41 contacts the third sensing piece 51 and the second sensing piece 42 contacts the fourth sensing piece 52, the second key function of the first sensor 4 is triggered. Through the cooperation of the first sensing piece 41, the second sensing piece 42, the third sensing piece 51 and the fourth sensing piece 52, the purpose of triggering the corresponding key function is achieved. By setting two sensors on the key, the key function that can be triggered by the combination of two keys or multiple keys can be triggered by only one key, which simplifies the operation method and improves the user experience.

[0055] In addition, the embodiment of the present invention also provides a method for key input, which is applied to a key including a keycap 3, a key switch 2, a first return spring 6, a second return spring 9, a first sensor 4 and a second sensor 5, and the first sensor 4 is located on the side surface of the keycap 3.

[0056] The method of key input includes the following steps: After the keycap 3 is pushed by an external force, it drives the key switch 2 to tilt towards the second sensor 5, so that the first sensor 4 contacts the second sensor 5, triggering the corresponding key function of the first sensor 4; The first return spring 6 and the second return spring 9 drive the key switch 2 to return to the static state, so that the first sensor 4 is separated from the second sensor 5 to complete the key input.

[0057] In the embodiment of the present invention, after the keycap 3 is pushed by an external force, it drives the key switch 2 to tilt towards the second sensor 5, so that the first sensor 4 contacts the second sensor 5, triggering the corresponding key function of the first sensor 4. This can be achieved by the following method: When the keycap 3 is pushed by an external force and drives the key switch 2 to tilt towards the third sensing piece 51 and the fourth sensing piece 52, the first sensing piece 41 contacts the third sensing piece 51. At this time, the first key function of the first sensor 4 is triggered. Then, the second sensing piece 42 contacts the fourth sensing piece 52. At this time, both the first sensing piece 41 contacting the third sensing piece 51 and the second sensing piece 42 contacting the fourth sensing piece 52 are in contact, triggering the second key function of the first sensor 4.

[0058] By setting two sensors on the key, the key function that can be triggered by the combination of two keys or multiple keys can be triggered by only one key, which simplifies the operation method and improves the user experience.

[0059] Furthermore, the embodiment of the present invention also provides a keyboard, which includes at least one key of the embodiment of the present invention; or includes the sensor of the embodiment of the present invention; or applies the method of key input of the embodiment of the present invention. By setting two sensors on the keys of the keyboard, the key function that can be triggered by the combination of two keys or multiple keys can be triggered by only one key, which simplifies the operation method and improves the user experience.

[0060] In summary, because the embodiment of the present invention adopts the technical means of setting two sensors on the key and triggering the corresponding function through the contact of the sensors, it overcomes the technical problem that the operation method of the combination keys in the prior art is not convenient to use. Furthermore, it achieves the technical effect that the key function realized by two keys or multiple key combinations can be realized by only one key, improving the user experience. Through the solution of the embodiment of the present invention, the user can realize the key function that can only be realized by multiple combination keys through one key, simplifying the operation method.

[0061] The present invention has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention fall within the scope of patent protection of the present invention.
