Background
Generally, most of the key structures of the existing keyboards have only on and off functions. When the key is pressed down, the switch circuit is switched on to input corresponding instruction, and when the key is released and rebounded, the switch circuit is switched off to finish the instruction. However, with the popularization of the electronic game, the existing keyboard can not meet the requirements of the electronic game players. For example, some game programs further require that the keyboard keys simultaneously exhibit speed, force and direction of motion, and continuous control over the course of motion. Therefore, the related keyboard with linear keys is generated, and the game program can determine the delay time or speed of the output instruction through the strength of pressing the keys so as to achieve the control effect.
However, for the user, the user needs to replace the corresponding keyboard according to different use environments or objects, which causes inconvenience in use. Therefore, how to increase the application range of the keyboard and improve the convenience is a problem that needs to be considered and solved by the related technical personnel.

Detailed Description
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1 is a schematic diagram of an input module according to a first embodiment of the invention. Fig. 2A and 2B are schematic diagrams respectively illustrating different types of keycap assemblies of the input module of fig. 1 separated from a base. Fig. 3A and 3B are side views of the keycap assembly and the base of fig. 2A and 2B, respectively, after assembly. It should be noted that fig. 1 to 3B are only schematic and simple to illustrate the relative positions of the components, and for reference, the actual number and the dimensional ratio thereof are not similar to those shown in fig. 1 to 3B. Referring to fig. 1, an input module 100 of the present invention is suitable for an electronic device 10 (e.g., a notebook computer), such as a built-in keyboard of the notebook computer.
Referring to fig. 2A and fig. 3A, it should be noted that fig. 2A only shows a single key structure in the input module 100 for the sake of illustration. In the present embodiment, the input module 100 includes a base 110 and a keycap assembly 120A. Base 110 includes a circuit board 112, a positioning plate 113, a scissors mechanism (scissors mechanism)114, and a base plate 115. The circuit board 112 is disposed on the bottom plate 115. The positioning plate 113 is disposed on the circuit board 112. The scissor mechanism 114 is disposed between the positioning plate 113 and the circuit board 112, and the positioning plate 113 can be moved up and down with respect to the circuit board 112 by the scissor mechanism 114. Here, the circuit board 112 is, for example, a thin film circuit, but not limited thereto.
The key cap assembly 120A includes a magnetic member 121A, a key cap 122A, and a shaft member 123A. Here, the shaft member 123A is a spring (e.g., a linear spring) assembled to the key cap 122A, and the key cap 122A is abutted to the circuit board 112 through the shaft member 123A. Accordingly, the positioning plate 113 and the keycap assembly 120A thereon are moved up and down relative to the base 110 by the scissors mechanism 114. When the key cap 122A is pressed, the spring is linearly deformed, and thus a linear key structure is constructed. The linear key structure, i.e., the key structure, can provide speed, force and direction of motion, and continuous control of the motion process according to the degree of pressing the key cap 122A, which is referred to herein as a "linear axis".
Further, as shown in fig. 2A, the openings of the circuit board 112 and the positioning plate 113 and the scissors mechanism 114 of the present embodiment form a mounting groove G, and the keycap assembly 120A is assembled to the base 110 so that the shaft member 123A is accommodated in the mounting groove G. In particular, the keycap assembly 120A of the present embodiment is adapted to be detached from the positioning plate 113. In other words, the input module 100 of the present embodiment allows the user to replace the keycap assembly 120A, so as to facilitate the corresponding required operating environment.
Referring to fig. 2B and 3B, most of the key structures shown in fig. 2B and 3B are the same as the key structures shown in fig. 2A and 3A and are not repeated, but the differences are: fig. 2B and 3B illustrate the use of keycap assembly 120B. The key cap assembly 120B includes a magnetic member 121B, a key cap 122B, and a shaft member 123B. Here, the shaft member 123B is a rubber dome (rubber dome) assembled to the key cap 122B. When the key cap 122B is pressed, the rubber dome is deformed non-linearly and thus constitutes a non-linear key structure which belongs to the standard key structure, i.e. only provides a simple on/off command, which is considered herein as the "standard axis".
As described above, fig. 2A and 2B illustrate that there are different types of keycap assemblies 120A, 120B that can be replaced by a user to facilitate different environments of use. Accordingly, in the input module 100 of the present embodiment, when the user replaces the keycap assemblies 120A and 120B, the input module 100 can therefore determine the type of the keycap assembly 120A or the keycap assembly 120B and provide the corresponding function instruction in the subsequent operation.
In detail, as shown in fig. 3A and 3B, the base 110 includes a magnetic sensor 111, such as a hall sensor. Fig. 4 is an electrical relationship diagram of some components in the input module of fig. 1. The input module 100 of the present embodiment further includes an identification unit 130 electrically coupled to the magnetic sensor 111. The identification unit 130 determines whether the user mounts the keycap assembly 120A or the keycap assembly 120B on the base 110 according to the magnetic line characteristics of the magnetic member 121A or 121B sensed by the magnetic sensor 111.
In the present embodiment, the size of the magnetic member 121A is different from the size of the magnetic member 121B. For example, the magnetic attraction of the magnetic element 121A is smaller than that of the magnetic element 121B, so that the amount and density of the magnetic lines of the magnetic element 121A are different from those of the magnetic element 121B. Therefore, when the user replaces the keycap assembly 120A or 120B, the identification unit 130 can identify the type of the keycap assembly 120A or 120B according to the magnetic line characteristics of the magnetic member 121A or the magnetic member 121B sensed by the magnetic sensor 111. In other embodiments, the magnetic field line characteristics of the magnetic member are not limited to the above.
Fig. 5 is a schematic diagram of magnetic flux characteristics of a keycap assembly of an input module according to an embodiment of the invention. It can be found through experiments that the magnetic sensor 111 can sense the magnetic flux characteristics when the keycap assembly 120A or the keycap assembly 120B is assembled to the base 110. Therefore, the identification unit 130 can further convert the magnetic force characteristics sensed by the magnetic sensor 111 into a voltage value to determine whether the shaft member 123A or the shaft member 123B is present, so as to obtain the relative relationship between the pressing stroke (mm) and the voltage (mv). For example, as shown in fig. 5, the shaft member 123A has corresponding voltage values at different strokes to form a voltage-stroke curve, and therefore, the voltage interval of the shaft member 123A can be obtained through a plurality of experiments, and thus, the determination reference can be summarized, which is similarly seen in the voltage-stroke curve of the shaft member 123B. In other words, the voltage-stroke curve obtained by the magnetic sensor 111 determines whether the "standard axis" or the "linear axis" is assembled on the base 110 at this time.
Fig. 6 is a schematic top view of an input module according to a second embodiment of the present invention. Fig. 7 is a schematic top view of an input module according to a third embodiment of the present invention. It should be noted that fig. 6 and 7 only show a single key structure in the input module. In addition, in fig. 6 and fig. 7, some irrelevant structures are omitted, and only the relative positions of the components are schematically and simply shown for reference, so as to facilitate the display and identify the different component parts.
Referring to fig. 6, in the present embodiment, the magnetic field line characteristic of the magnetic member is, for example, the distribution orientation of the magnetic field lines. For example, in one version of the keycap assembly, the magnetic member 121C on the keycap 122C is N-pole in the first position 1211 shown in fig. 6 and S-pole in the second position 1212 shown in fig. 6. In another type of keycap assembly, the magnetic member 121C is configured upside down, i.e., the magnetic member 121C is rotated 180 degrees such that the magnetic member 121C is S-pole in the first position 1211 shown in fig. 6 and N-pole in the second position 1212 shown in fig. 6. Thereby, the magnetic sensor 111C on the circuit board 112C can identify the type of the keycap assembly by sensing the magnetic line characteristics of the magnetic members in different distribution orientations.
Referring to fig. 7, in the present embodiment, the magnetic field line characteristic of the magnetic member is, for example, the distribution orientation of the magnetic field lines. For example, in one type of keycap assembly, the first end 1211D of the magnetic member 121D on the keycap 122D is N-pole and the second end 1212D is S-pole. An included angle α exists between the orthographic projection of the magnetic member 121D on the base 110D and the magnetic sensor 111D on the circuit board 112D. The figures depict the magnetic elements of another type of keycap assembly to facilitate alignment. For example, the first end 1211E of the magnetic element 121E is an N-pole, the second end 1212E is an S-pole, and an included angle β exists between the forward projection of the magnetic element 121E on the base and the magnetic sensor 111D on the circuit board 112D. Here, the angle β is larger than the angle α. Therefore, the identification unit can identify the type of the keycap assembly according to the magnetic line characteristics of the magnetic members in different distribution directions sensed by the magnetic sensor.
FIG. 8 is a flow chart of an input module replacing the keycap assembly according to an embodiment of the invention. Referring to fig. 8, after the user performs step S01, i.e., replaces the keycap assemblies (e.g., replaces the keycap assemblies 120A and 120B), in step S02, the magnetic members 121A and 121B have different magnetic field lines for different types of keycap assemblies 120A and 120B. Furthermore, as shown in fig. 4, the control module 200 of the electronic device 10 (shown in fig. 1) is electrically coupled to the identification unit 130 and the magnetic sensor 111, so that the control module 200 can determine the type of the keycap assembly (the keycap assembly 120A or the keycap assembly 120B) according to the magnetic force line characteristics of the magnetic member (such as the magnetic member 121A or the magnetic member 120B) sensed by the magnetic sensor 111, and then execute step S03 to automatically detect and switch to the corresponding shaft mode. Thus, the user may be left out of the step of replacing the keycap assembly and then clicking on the linear or standard mode in the system. On the other hand, when the control module 200 cannot determine what the key structure is, which may represent the situation that the keycap assembly is not assembled to the mounting groove G or there is another assembling error, the user returns to step S01 from step S02 and re-executes the step of replacing the keycap assembly.
In the present embodiment, the control module 200 of the electronic device 10 (shown in fig. 1) provides an interface (interface) according to the type of keycap assembly (keycap assembly 120A or keycap assembly 120B). Specifically, the operation interface can be used for setting the pressing stroke and the triggering mechanism of the keycap assembly. For example, as shown in fig. 3A and 3B, the height H1 of the key cap 122A of the non-linear key structure relative to the circuit board 112 of the base 110 is greater than the height H2 of the key cap 122B of the linear key structure relative to the circuit board 112 of the base 110. Therefore, the user can set the pressing stroke and the trigger mechanism of the keycap assembly at step S04, and close the operation interface after the setting is completed. Next, step S05 is executed to turn on the magnetic sensor 111 to wait for detecting the next shaft change.
In summary, in the above embodiments of the invention, the base of the input module includes the magnetic sensor, and the keycaps of the different types of keycap assemblies are respectively configured with different types of magnetic members. The magnetic members have different magnetic force magnitudes, or the magnetic members have different distances, orientations or angles with the magnetic sensor, so that the magnetic force line characteristics generated by the magnetic members on different types of keycap assemblies have different characteristics. The magnetic force line characteristics of the magnetic part are sensed through the magnetic sensor, so that the control module of the electronic device can judge the type of the keycap component according to the magnetic force line characteristics of the magnetic part sensed by the magnetic sensor, and the effects of automatically detecting and switching to the corresponding shaft mode are achieved. Therefore, the user can save the step of clicking the linear or standard mode by the system after replacing the keycap assembly, and the operation convenience is further improved. Moreover, a user can set the pressing stroke of the keycap through an operation interface of the electronic device, so that the keycaps of different keycap components have the same height relative to the circuit board of the base, and the operation of the user is facilitated.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
