Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "plurality" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0043] Stylus pens are widely used in tablet computers, office computers, mobile phones and other fields. Existing stylus pens generally include a pen body and a power module and circuit components arranged in the pen body. The power module on the stylus is generally connected to the contacts on the circuit board structure through positive and negative contacts. However, during the installation of the power module, improper operation may cause the positive and negative poles on the power module to be incorrectly connected to the contacts on the circuit board structure, resulting in the electrodes on the power module being reversed or short-circuited.

[0044] In view of this, an embodiment of the present application provides a stylus pen to overcome at least one of the above technical problems.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In the embodiment of the present application, the stylus pen includes a pen body 10, a power module 20, and a circuit assembly 30. The pen body 10 is provided with a receiving cavity 11, and the receiving cavity 11 is used to provide a space for receiving other components. The pen body 10 can protect and support other structures in the stylus pen. The power module 20 is at least partially located in the receiving cavity 11. The power module 20 includes a main body 21, a first connecting portion 22, and a second connecting portion 23. The first connecting portion 22 is connected to the main body 21 and is located in the axial direction of the main body 21. The second connecting portion 23 is arranged around the first connecting portion 22 and is connected to the main body 21. The power module 20 is an important component of the stylus pen and is used to provide electrical energy to the stylus pen. The circuit assembly 30 is located in the receiving cavity 11 and is connected to the pen body 10. The circuit assembly 30 includes a first contact portion 31 and a second contact portion 32 arranged toward the power module 20. The first contact portion 31 is electrically connected to the first connecting portion 22, and the second contact portion 32 is electrically connected to the second connecting portion 23. The first connection part 22 is connected to the main body 21. Specifically, the first connection part 22 can be arranged at the center of the main body 21 facing the circuit assembly 30, that is, located in the axial direction of the main body 21. Therefore, when the power module 20 is embedded in the accommodating cavity 11, no matter how the power module 20 rotates, the first connection part 22 and the first contact part 31 can always be electrically connected; and the second connection part 23 is arranged around the first connection part 22. No matter how the second connection part 23 rotates, a part of the second connection part 23 can always be electrically connected to the second contact part 32. The user does not need to pay special attention to the installation angle when installing the power module 20, which ensures that the first connection part 22 and the first contact part 31, the second connection part 23 and the second contact part 32 are correctly connected, and avoids the first connection part 22 and the first contact part 31, the second connection part 23 and the second contact part 32 being connected in reverse due to incorrect installation angle, which plays a certain fool-proof role. The first connection portion 22 can be a positive electrode or a negative electrode, the second connection portion 23 is an electrode with a polarity opposite to that of the first connection portion 22 , and the first contact portion 31 and the second contact portion 32 correspond to the polarities of the first connection portion 22 and the second connection portion 23 , respectively.

[0046] See also Figure 6 and Figure 7In some embodiments, the second connection portion 23 includes a plurality of connection sub-bodies 231 arranged at intervals, and the second contact portion 32 includes a plurality of contact sub-bodies 321 arranged at intervals, and each connection sub-body 231 is electrically connected to a contact sub-body 321. Specifically, the overall shape of the power module 20 may be a cylinder or a cuboid. When the overall shape of the power module 20 is a cuboid, the second connection portion 23 may not only be in the shape of a ring, arranged around the first connection portion 22, but may also be a plurality of connection sub-bodies 231 symmetrically arranged about the first connection portion 22. Correspondingly, the second contact portion 32 may also be a plurality of contact sub-bodies 321 arranged at intervals. When the power module 20 having an overall shape of a cuboid is installed, each connection sub-body 231 may be electrically connected to a contact sub-body 321 regardless of whether the front side faces upward or the back side faces upward.

[0047] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 In some embodiments, the first contact portion 31 has a first connection groove 311, the first connection portion 22 is embedded in the first connection groove 311, and the circuit assembly 30 includes a first conductive member 33, which is disposed in the first connection groove 311 and wraps the first connection portion 22. By embedding the first connection portion 22 in the first connection groove 311, the first connection portion 22 and the first contact portion 31 can have a larger contact area, and the first conductive member 33 is disposed inside the first connection groove 311. The first conductive member 33 can be made of conductive rubber material, has a certain degree of flexibility, and is fixed inside the first connection groove 311. When the first connection portion 22 is embedded in the first connection groove 311, the first conductive member 33 will wrap around the first connection portion 22, thereby increasing the connection stability between the first connection portion 22 and the first contact portion 31, and at the same time, the gap between the first connection portion 22 and the inner wall of the first connection groove 311 can be filled, thereby further increasing the contact area between the two.

[0048] The second contact portion 32 has a second connection groove 322, and the second connection portion 23 is embedded in the second connection groove 322. The circuit assembly 30 includes a second conductive member 34, and the second conductive member 34 is disposed in the second connection groove 322 and wraps the second connection portion 23. By embedding the second connection portion 23 in the second connection groove 322, the second connection portion 23 and the second contact portion 32 can have a larger contact area. At the same time, the second conductive member 34 is disposed inside the second connection groove 322. The second conductive member 34 can also be made of conductive rubber material, and has the same function as the first conductive member 33, which increases the connection stability between the second connection portion 23 and the second contact portion 32. At the same time, the gap between the second connection portion 23 and the inner wall of the second connection groove 322 can be filled, and the contact area between the two can be further increased.

[0049] Furthermore, for the connection form of setting multiple connecting sub-bodies 231 and multiple contact sub-bodies 321, grooves can also be opened on the multiple contact sub-bodies 321 so that the corresponding connecting sub-bodies 231 can be embedded therein, and conductive parts can also be set inside the contact sub-body 321 to fill the gap, increase the contact area, and improve the stability of the connection.

[0050] See also Fig. 9 , Fig.10 , Fig.11 and Fig.12 In some embodiments, the pen body 10 has a placement groove 12 connected to the accommodating cavity 11, and the function of the placement groove 12 is to provide a specific space for placing other structures. The stylus pen also includes a first magnetic ring 40 and a second magnetic ring 50. The first magnetic ring 40 is placed in the placement groove 12 and connected to the pen body 10. The second magnetic ring 50 is connected to the main body 21 and is arranged around the main body 21. The second magnetic ring 50 is embedded in the placement groove 12 and is magnetically connected to the first magnetic ring 40. This connection method can ensure that the second magnetic ring 50 is firmly connected to the first magnetic ring 40, that is, after the power module 20 is partially embedded in the accommodating cavity 11, the power module 20 can be stably connected to the pen body 10, and it is also convenient to remove the power module 20 from the pen body 10, which is conducive to the disassembly and replacement of the power module 20.

[0051] See also Figure 3 and Fig.11In some embodiments, the main body 21 includes a first main body 211 and a second main body 212. The first main body 211 is located in the accommodating cavity 11, and the first connecting portion 22 and the second connecting portion 23 are both connected to the side of the first main body 211 facing the circuit assembly 30. The second main body 212 is located outside the accommodating cavity 11 and is connected to the side of the first main body 211 away from the circuit assembly 30. In other words, the main body 21 is one of the power module components of the stylus pen, which is used to provide power supply. It consists of two sub-parts: the first main body 211 and the second main body 212. The first main body 211 is located inside the accommodating cavity 11 of the stylus pen. The first connecting portion 22 and the second connecting portion 23 are both connected to the first main body 211, and they are located on the side of the first main body 211 facing the circuit assembly 30. Such a layout can facilitate the connection and management of the electrical connection between the circuit assembly 30 and the power module 20. The first main body 211 undertakes the key function of power transmission, ensuring the normal supply of power and maintaining the normal function of the stylus pen. The second body 212 is located outside the stylus receiving cavity 11 and is connected to a side of the first body 211 away from the circuit assembly 30. The second body 212 is a charging structure that can be connected to an external power source, and the external power source charges the first body 211 through the second body 212.

[0052] See also Fig.11 and Fig.12 In some embodiments, the first body 211 includes a mounting shell 2111, a power supply 2112, and a mounting seat 2113. The mounting shell 2111 is connected to the second body 212, and the mounting shell 2111 has a mounting cavity 21111. The power supply 2112 is located in the mounting cavity 21111 and is electrically connected to the second body 212. The mounting seat 2113 is covered in the mounting cavity 21111 and is connected to a side of the mounting shell 2111 away from the second body 212. The mounting seat 2113 is electrically connected to the power supply 2112, and the mounting seat 2113 is electrically connected to the first connection portion 22 and the second connection portion 23. In other words, the first body 211 is composed of a plurality of parts, including the mounting shell 2111, the power supply 2112, and the mounting seat 2113. The mounting shell 2111 is a part of the first body 211 and is connected to the second body 212. The mounting shell 2111 has a mounting cavity 21111 for accommodating the power supply 2112, so that the mounting shell 2111 can protect the power supply 2112. The mounting shell 2111 provides a stable support structure by connecting to the second body 212. The power supply 2112 is electrically connected to the second body 212, so that when the structure is charged through the second body 212, the current can be transferred to the power supply 2112. The power supply 2112 installed in the mounting cavity 21111 provides the required power supply for the stylus. The power supply 2112 may include a battery or other power source.

[0053] The mounting seat 2113 is covered on the mounting cavity 21111 and connected to the side of the mounting shell 2111 away from the second body 212. The mounting seat 2113 is electrically connected to the power supply 2112 and to the first connection portion 22 and the second connection portion 23. By being electrically connected to these connection portions, the mounting seat 2113 can provide a path for power transmission between the power supply 2112 and the circuit assembly 30.

[0054] See also Fig.11 and Fig.12 In some embodiments, the mounting shell 2111 has a plurality of first connection holes 21112 arranged at intervals, and the first connection holes 21112 connect the accommodating chamber 11 and the mounting chamber 21111; the pen body 10 has a plurality of second connection holes 13 arranged at intervals, and the second connection holes 13 connect the accommodating chamber 11. When the power source 2112 is charged or discharged, a certain amount of heat will be generated.
