The pressing detection module is not shown in the figure and may be disposed on a surface of the upper case facing the accommodation space. The movement detection module 14 is configured to generate a second signal when the operation component 12 is forced to move in a second direction and/or a third direction relative to the housing 11, where the second direction (e.g., the X direction shown in fig. 3) and the third direction (e.g., the Y direction shown in fig. 3) are located on the same plane, and a plane in which the second direction and the third direction are located and the first direction satisfy a vertical condition, where the vertical condition is vertical within a tolerance allowable range.

In this way, the rod 1212 is restricted by the connecting portion 1222 to move in the first direction, when a pressing force is applied to the head 1211, the rocking bar 121 moves downward (in the Z direction in fig. 3) by the pressing force, and after the pressing force is released, the rocking bar 121 is reset by the elastic member 123.

With reference to fig. 4 and 5, when the mouse control is implemented by the keyboard, the method includes:

s10: the pressing detection module and the movement detection module 14 sense the operation of the operation member 12 by the user.

When the keyboard is generally used, the input assembly 10 is in a default mode, the display lamp 21 in the default mode is long and bright, and the page turning up and down or left and right can be realized by applying a pushing force to the operation part 12; when the mode needs to be switched, the pressing operation part 12 is switched into a special mode, when the mode is in the special mode, the special mode display lamp 22 is on for a long time, a left click command of the mouse is executed by operating the left direction key 32, a right click command of the mouse is executed by operating the right direction key 33, a mouse wheel command is executed by operating the lower direction key 31, meanwhile, the operation part 12 is pushed, the mouse pointer can be controlled to form displacement, the movement form of the mouse pointer is different according to the direction and the size of the applied pushing force, and the concrete principle is represented as follows: when pushing operating means 12, operating means 12 transmits the driving force to removal detection module 14 through transmission seat 124, calculates the resistance change that removes detection module 14 through the algorithm, and control module controls the displacement of mouse pointer according to the resistance change, and when no longer pushing operating means 12, elastic component 123 kick-backs and drives transmission seat 124 and operating means 12 and reset.

In an embodiment not shown, the special mode can be switched to the default mode by pressing the up direction key 34, and the up direction key 34 is set as a mode switching key in this embodiment, which is more convenient and can provide greater convenience than the mode switched by the input assembly 10. It should be understood that most of the key caps on the keyboard protrude from the surface of the keyboard body for the purpose of enhancing comfort in use, but the head 1211 of the operating member 12 may be lower than the surface of the keyboard body for the purpose of beauty.

In summary, the invention has the following advantages besides the advantage of small occupied space:

The standard direction key is set as a part for realizing the mouse function, and in a special mode, the left direction key 32 can execute a left mouse click command, and the right direction key 33 can execute a right mouse click command, so that most of instructions can be finished by replacing the mouse, and the operability is high.

6. Under a general use environment, such as turning over a document or a webpage, the control module can be set to be in a special mode, and the page turning over of the document can be completed by pressing the down direction key 31, so that the convenience is high.

7. The control signal is obtained by calculating the resistance value change, the control signal comprises an orientation signal and a speed signal, the orientation signal can control the moving direction of the mouse pointer through the force application direction, the speed signal can obtain the traveling speed of the mouse pointer through a formula and an algorithm, and the experience of an operator is greatly improved.
