Obviously, the described embodiment is a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0033] The embodiments of the utility model will be described below in combination with Figures 1 to 8 .
[0034] According to the embodiment of the utility model, on the one hand, an electronic pen is provided, such asFigure 1 and Figure 2 As shown, the electronic pen includes a pen body 1, a fastener, a circuit board 3, and a battery module 4. The pen body 1 has a pen tip and a receiving cavity 10, and the fastener is connected to the end of the pen body 1 furthest from the pen tip. The circuit board 3 and the battery module 4 are both located within the receiving cavity 10.
[0035] Specifically, the circuit board 3 has a first electrical connection portion 32 and a second electrical connection portion 33 on the side facing the pen cap 2. The first electrical connection portion 32 is located on the axis of the receiving cavity 10, and the second electrical connection portion 33 is coaxially and spaced apart on the outside of the first electrical connection portion 32 so as to be mutually insulated from the first electrical connection portion, and the second electrical connection portion 33 is annular.
[0036] It should be noted that both the first electrical connection portion 32 and the second electrical connection portion 33 extend around the axis of the receiving cavity 10. Furthermore, this invention does not specifically limit the shape and structure of the first electrical connection portion 32, as long as it can abut against the electrical connector 42 to achieve the electrical connection function. For example, the first electrical connection portion 32 can be circular, annular, rectangular, etc.
[0037] Furthermore, the battery module 4 is located between the circuit board 3 and the fastener. The battery module 4 includes a battery 41 and two electrical connectors 42, which are respectively disposed corresponding to the first electrical connection portion 32 and the second electrical connection portion 33.

The first electrical connector 32 located on the axis of the receiving cavity 10 and the annular second electrical connector 33 form a 360° foolproof design. When the battery module 4 is installed into the receiving cavity 10, even if it rotates around the axis of the pen body 1, the two electrical connectors 42 can still correspond to the positions of the first electrical connector and the second electrical connector, which facilitates the installation of the battery module 4 and improves the convenience of replacing the battery module 4.
[0039] Specifically, in some embodiments, such as Figure 6 As shown, the circuit board 3 includes a board body 31, a first electrical connection portion 32 and a second electrical connection portion 33 are both disposed on the board body 31, and the board body 31 has an insulating portion 34, which is coaxially disposed between the first electrical connection portion 32 and the second electrical connection portion 33 so that the first electrical connection portion 32 and the second electrical connection portion 33 are mutually insulated.

The tube body 421 forms a first end, and the head 422 forms a second end. The heads 422 of the two electrical connectors 42 respectively abut against the first electrical connection part 32 and the second electrical connection part 33 to achieve electrical connection with them. In this embodiment, the elastic part 423 can support the head 422 to strengthen the abutment between the head 422 and the first or second electrical connection part 32, ensuring the reliability of the electrical connection. By abutting against the first and second electrical connection parts 32 and 33, the two electrical connectors 42 thus achieve electrical connection, further improving the convenience of replacing the battery module 4.
