The size of the pen tip 11 in the pen housing 10 of the capacitive pen is related to the precision of the capacitive pen, and the finer the pen tip 11 is, the higher the precision of the capacitive pen is, so that the writing requirement of a user can be met. However, for the ultra-small-sized built-in plug-in capacitive pen, the charging electrode 30 is basically arranged at the tail of the pen shell 10 of the capacitive pen and protrudes out of the pen shell 10 of the whole pen, so that the overall size of the capacitive pen cannot be designed to be smaller, that is, the pen point 11 of the capacitive pen cannot be designed to be smaller, so that a host of a touch screen in communication connection with the capacitive pen cannot be designed to be thinner, and a user needs to carry a charger with the host to charge the capacitive pen, which is not convenient enough to use and cannot meet the use requirement of the user on the capacitive pen in work or life.

The pen housing 10 includes a nib 11 and a barrel 12 connected to the nib 11. The cross-sectional shape of the nib 11 is generally triangular, which is more advantageous for the user to write. Alternatively, the nib 11 may be made of rubber, silica gel, metal, soft fiber, etc., and is not particularly limited herein. Alternatively, the barrel 12 may be manufactured in a cylindrical shape, or may be manufactured in a hexagonal prism shape.

Alternatively, the pen holder 12 may be made of metal such as aluminum alloy and aviation aluminum, or plastic such as rubber, and is not particularly limited herein.

Alternatively, the communication electrode 20 includes at least one transmitting electrode 21 and one receiving electrode 22, and the specific number is not particularly limited herein.

And the energy storage chip is used for storing energy for the capacitance pen when the capacitance pen is in a charging mode. Alternatively, the sources and types of the main control chip and the energy storage chip are not particularly limited, and the main control chip and the energy storage chip can be obtained through commercial methods.

Specifically, in the practical application of the capacitive pen, when the capacitive pen is in the working mode, the control component 50 opens the first loop and controls the communication electrode 20 to contact the touch screen in the working state of the preset voltage for interactive communication, so as to meet the use requirement of the user in writing. When the control assembly 50 detects that the voltage difference between the different ones of the communication electrodes 20 is not within the preset voltage range, the control assembly 50 switches the capacitive pen from the operation mode to the charging mode. The control assembly 50 closes the first loop and opens the second loop, so that the charging electrode 30 is connected with the battery assembly 40, and charges the control assembly 50, and the user can meet the use requirement of the user in charging without carrying a charger.

The capacitive pen and the electronic equipment component are convenient to charge; the capacitive pen comprises a pen shell 10, a communication electrode 20, a charging electrode 30, a battery assembly 40 and a control assembly 50, wherein the pen shell 10 comprises a pen point 11 and a pen holder 12, the communication electrode 20 is arranged in the pen point 11, the charging electrode 30, the battery assembly 40 and the control assembly 50 are all arranged in the pen shell 10, the battery assembly 40 is electrically connected with the charging electrode 30, and the control assembly 50 is electrically connected with the communication electrode 20, the charging electrode 30 and the battery assembly 40 respectively; the electronic device assembly includes a touch screen and the capacitive pen.

In addition, the transmitting electrode 21 and the receiving electrode 22 are integrated into one electrode, so that the installation space of the capacitance pen can be reduced, and the volume of the capacitance pen can be further reduced.

Thus, in practical application of the capacitive pen, when the capacitive pen is in contact with the touch screen, the receiving electrode 22 receives the second signal from the touch screen based on the control of the control component 50 to determine the inclination angle of the capacitive pen; meanwhile, the transmitting electrode 21 transmits a first signal to the touch screen under the control of the control component 50, so that the touch screen can determine the azimuth angle of the capacitive pen according to the first signal, and bidirectional communication between the capacitive pen and the touch screen is realized.

In order to ensure that the first signal is not too divergent, the host of the touch screen cannot analyze the pen-down coordinates of the capacitive pen, the capacitive pen generally performs ground shielding on the first signal. The present utility model improves the above-described problems by providing the charging anode 32.

Further, the charging negative electrode 32 and the charging positive electrode 31 are arranged in the pen shell 10, a certain installation space is not required to be reserved at the tail part of the pen holder 12 so as to install the charging negative electrode 32 and the charging positive electrode 31, so that the size of the capacitance pen can be designed to be smaller, and a touch screen in communication connection with the capacitance pen can be designed to be thinner, and therefore the use requirement of a user on the accuracy of the capacitance pen is met.
