Background
In general, the key structure of the existing keyboard mostly has only on and off functions. When the key is pressed down, the switch circuit is turned on to input corresponding instructions, and when the key is released and rebounded, the switch circuit is turned off to end the instructions. However, with the popularization of electronic competition games, the existing keyboard cannot meet the requirements of electronic competition players. For example, some game programs require further keyboard keys that can simultaneously exhibit speed, force, direction of motion, and continuous control over the course of motion. Accordingly, the related keyboards with linear keys are also generated, which can enable the game program to determine the delay time or speed of the output command by the strength of pressing the keys so as to achieve the control effect.
However, for the user, the corresponding keyboard needs to be replaced according to different use environments or objects, which causes inconvenience in use. Therefore, how to increase the application range of the keyboard and to increase the convenience is a problem that needs to be considered and solved by the related technicians.

Detailed Description
Reference will now be made in detail to the exemplary embodiments of the present 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 views of a different type of key cap assembly of the input module of fig. 1 separated from the base. Fig. 3A and 3B are side views of the key cap assembly and the base of fig. 2A and 2B, respectively, after assembly. It should be noted that fig. 1 to 3B only schematically and simply show the relative positions of the components, and for reference only, the actual number and size ratio thereof are not similar to those shown in fig. 1 to 3B. Referring to fig. 1, the 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, and in other embodiments, the electronic device and the input module thereof of the present invention may be an external keyboard of a desktop computer or other computer systems with physical keyboards.
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 illustration. In the present embodiment, the input module 100 includes a base 110 and a key cap assembly 120A. The base 110 includes a wiring board 112, a positioning board 113, a scissor mechanism (scissors mechanism) 114, and a bottom plate 115. The circuit board 112 is disposed on the bottom plate 115. The positioning board 113 is disposed on the circuit board 112. The scissors mechanism 114 is disposed between the positioning plate 113 and the circuit board 112, and the positioning plate 113 can be lifted and lowered relative to the circuit board 112 by the scissors 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 wiring board 112 through the shaft member 123A. Accordingly, the positioning plate 113 and the key cap assembly 120A thereon can move 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 constitutes a linear key structure. The linear key structure is herein referred to as a key structure that provides speed, force, direction of motion, and continuous control of the motion process, which is referred to herein as a "linear axis", depending on the degree to which the key cap 122A is pressed.
Further, as shown in fig. 2A, the openings of the circuit board 112 and the positioning board 113 and the scissors mechanism 114 form a mounting groove G, and the key cap assembly 120A is assembled to the base 110 such that the shaft member 123A is accommodated in the mounting groove G. In particular, the key cap 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 can be used for the user to replace the key cap assembly 120A, so as to be beneficial to the corresponding required operating environment.
Referring to fig. 2B and 3B, the key structure shown in fig. 2B and 3B is largely the same as that shown in fig. 2A and 3A, and is not repeated, except that: fig. 2B and 3B illustrate the use of a key cap 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 nonlinearly and thus constitutes a nonlinear key structure which belongs to a standard key structure, i.e., provides only a simple instruction of on/off (on/off), which is referred to herein as a "standard axis".
As described above, fig. 2A and 2B illustrate different types of key cap assemblies 120A, 120B that can be replaced by a user to accommodate different usage environments. Accordingly, in the input module 100 of the present embodiment, when the user replaces the key cap assembly 120A, 120B, the input module 100 can determine the type of the key cap assembly 120A or the key cap assembly 120B to provide the corresponding function command in the subsequent operation.
In detail, as shown in fig. 3A and 3B, the base 110 includes a magnetic sensor 111, for example, a hall sensor. Fig. 4 is a schematic electrical relationship of a portion of the 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 key cap assembly 120A or the key cap assembly 120B is mounted on the base 110 according to the magnetic force 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 force of the magnetic element 121A is smaller than that of the magnetic element 121B, so that the number and the degree of the magnetic lines of force of the magnetic element 121A are different from those of the magnetic element 121B. Therefore, when the user replaces the key cap assembly 120A or 120B, the identification unit 130 can identify the pattern of the key cap assembly 120A or 120B according to the magnetic force line characteristics of the magnetic member 121A or the magnetic member 121B sensed by the magnetic sensor 111. In other embodiments, the magnetic force line characteristics of the magnetic member are not limited as described above.
Fig. 5 is a schematic diagram illustrating magnetic force line characteristics of a key cap assembly of an input module according to an embodiment of the invention. As can be seen through experiments, the magnetic sensor 111 can sense the magnetic force line characteristics due to the assembly of the key cap assembly 120A or 120B to the base 110. Therefore, the identification unit 130 can further convert the magnetic force line characteristics sensed by the magnetic sensor 111 into a voltage value to determine whether the magnetic force line characteristics are the shaft member 123A or the shaft member 123B, so as to obtain the relative relationship between the pressing stroke (millimeter) and the voltage (millivolt). For example, as shown in fig. 5, the shaft member 123A has corresponding voltage values on different strokes to form a voltage-stroke curve, and therefore, the voltage interval of the shaft member 123A can be obtained through multiple experiments, so that the judgment reference can be generalized, which is similar to the voltage-stroke curve of the shaft member 123B. In other words, the voltage-stroke curve obtained by the magnetic sensor 111 can be used to determine 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, the non-relevant structure is partially omitted in fig. 6 and 7, and the relative positions of the components are simply shown only schematically and for reference only, so as to facilitate the display and identification of the component parts with differences.
Referring to fig. 6, in the present embodiment, the magnetic force line characteristic of the magnetic element is, for example, the distribution orientation of the magnetic force lines. For example, in one version of the key cap assembly, the magnetic element 121C on the key cap 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 version of the key cap assembly, the magnetic element 121C is arranged upside down, i.e., the magnetic element 121C is rotated 180 degrees such that the magnetic element 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. Thus, the magnetic sensor 111C on the circuit board 112C can identify the type of the key cap assembly by sensing the magnetic force line characteristics of the magnetic members of different distribution orientations.
Referring to fig. 7, in the present embodiment, the magnetic force line characteristic of the magnetic element is, for example, the distribution orientation of the magnetic force lines. For example, in one version of the key cap assembly, the first end 1211D of the magnetic member 121D on the key cap 122D is N-pole and the second end 1212D is S-pole. An angle α exists between the front projection of the magnetic element 121D on the base 110D and the magnetic sensor 111D on the circuit board 112D. The drawings depict the magnetic elements of another type of key cap assembly to facilitate alignment. For example, the first end 1211E of the magnetic element 121E is N-pole, the second end 1212E is S-pole, and an angle β exists between the front 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 force line characteristics of the magnetic pieces with different distribution orientations sensed by the magnetic sensor.
FIG. 8 is a flow chart of the input module for replacing the key cap assembly according to an embodiment of the invention. Referring to fig. 8, when the user performs step S01, i.e. after replacing the key cap assembly (e.g. between the key cap assemblies 120A and 120B), then in step S02, the magnetic members 121A and 121B have different magnetic force line characteristics for different types of key cap 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 key cap assembly (the key cap assembly 120A or the key cap assembly 120B) according to the magnetic force line characteristics of the magnetic element (such as the magnetic element 121A or the magnetic element 120B) sensed by the magnetic sensor 111, and then execute the step S03 to automatically detect and switch to the corresponding shaft mode. Therefore, the user can omit the step of replacing the key cap assembly and then entering the system to click the linear or standard mode. On the other hand, when the control module 200 cannot determine what the key structure is, it may represent that the key cap assembly is not yet assembled to the mounting groove G or that there is another assembly error, and the user returns to step S01 from step S02 and re-performs the step of replacing the key cap 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 the key cap assembly (the key cap assembly 120A or the key cap assembly 120B). Specifically, the operation interface can be used to set the pressing stroke and the triggering mechanism of the key cap 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 triggering mechanism of the key cap assembly in 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 detect the next shaft replacement.
In summary, in the above embodiment of the invention, the base of the input module includes a magnetic sensor, and different types of magnetic members are respectively disposed on the key caps of different types of key cap assemblies. The magnetic pieces have different magnetic force magnitudes respectively, or the magnetic pieces have different distances, orientations or angles with the magnetic sensor respectively, so that the magnetic force line characteristics generated by the magnetic pieces on the key cap assemblies of different types are different. The magnetic force line characteristics of the magnetic piece are sensed by the magnetic sensor, so that the control module of the electronic device can judge the type of the key cap assembly according to the magnetic force line characteristics of the magnetic piece sensed by the magnetic sensor, and the effect of automatically detecting and switching to the corresponding shaft mode is achieved. Therefore, the user can omit the step of replacing the key cap assembly and then entering the system to point the linear mode or the standard mode, thereby improving the operation convenience. Furthermore, the user can set the pressing stroke of the key cap through the operation interface of the electronic device, so that the heights of the key caps of different key cap assemblies relative to the circuit board of the base are the same, and the operation of the user is facilitated.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
