Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 and fig. 3, the capacitive pen provided in this embodiment includes a pen outer housing 1 and a plastic inner housing 2 disposed in the pen outer housing 1, a main board is disposed in the plastic inner housing 2, a bluetooth module is integrated on the main board, and the capacitive pen establishes communication connection with an electronic device through the bluetooth module. The magnet 6 is also embedded in the plastic inner shell 2, and is magnetically attracted on the electronic equipment through the magnet 6 when not in use, so that the capacitance pen is prevented from being lost. In addition, a motion sensing element is arranged in the pen holding position of the front section of the capacitance pen, the motion sensing element is arranged between the plastic inner shell 2 and the pen outer shell 1, and the motion sensing element is electrically connected with the main board. The motion sensing element is used for sensing the finger motion of the user to generate a current signal, the current signal is sent to the main board, and the main board processes the current signal to identify the finger motion of the user.
The finger action of the user can comprise single click/double click/three click/multiple click/sliding gesture and other actions of the index finger of the user at the pen holding position, and the action sensing element generates different analog electric signals after sensing different actions. The main control IC on the main board processes the analog electric signals sent by the motion sensing element according to a preset processing method, so that the finger motion of a user is identified.
The corresponding relation between the finger action and the triggering of the shortcut function is preset in the main control IC, when the main control IC recognizes the finger action of the user, the function which the user wants to trigger/switch can be confirmed according to the corresponding relation, and then the corresponding function of the electronic equipment is controlled through the Bluetooth module. The main control IC can also identify whether the user holds the capacitance pen according to the analog electric signal sent by the action sensing element, so that the functions of pen holding starting and pen placing and shutting down are realized, and the endurance time of the capacitance pen is prolonged.
In this embodiment, as shown in fig. 2-3, the motion sensing element may include a flexible circuit board 4, where the surface of the flexible circuit board 4 is integrated with a transverse electrode and a longitudinal electrode that are disposed perpendicular to each other, where the two groups of electrodes intersect, a capacitor will be formed, that is, the two groups of electrodes respectively form two poles of the capacitor. The transverse electrode and the longitudinal electrode are electrically connected with the main board. The flexible circuit board 4 is wrapped on the outer surface of the plastic inner shell 2.
The working principle of the motion sensing element adopting the structural design is realized by referring to the working principle of a mutual capacitance type touch screen. Specifically, when a finger touches the pen holding surface of the pen housing 1, the coupling between the two electrodes near the touch point is affected, thereby changing the capacitance between the two electrodes. When the mutual capacitance is detected, the transverse electrodes sequentially send out excitation signals, and all the longitudinal electrodes simultaneously receive signals, so that the capacitance value of all the intersection points of the transverse electrodes and the longitudinal electrodes can be obtained.
When the human finger approaches, the local capacitance is reduced, and the coordinates of each touch point can be calculated according to the capacitance variation data. Thus, even if there are a plurality of touch points, the true coordinates of each touch point can be calculated. The main control IC on the main board can recognize finger actions according to the change of the coordinates of the touch point.
In this embodiment, the motion sensing element may also be a conductive medium 5.

During touch detection, a main control IC on a main board sequentially detects the transverse wire array and the longitudinal wire array respectively, and respectively determines transverse coordinates and longitudinal coordinates according to the change of the capacitance before and after touch, and then the transverse coordinates and the longitudinal coordinates are combined into planar touch coordinates. The main control IC on the main board can recognize finger actions according to the change of the coordinates of the touch point.
