[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0013] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0014] The following describes an electronic pen provided in an embodiment of the present application in detail through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0015] Figure 1 A schematic diagram of the structure of the electronic pen provided in the embodiment of the present application is shown as follows: Figure 1 As shown, the electronic pen may include: a body, a pen cap and an integrated circuit 30.

[0016] In the embodiment of the present application, the integrated circuit 30 is placed inside the body for feeding the antenna. To facilitate assembly and welding of the integrated circuit 30, the integrated circuit 30 and other electronic components of the electronic pen are integrated on a printed circuit board (PCB).

[0017] The pen cap may include a first pen cap part 11 and a second pen cap part 12. The first pen cap part 11 is made of conductive material, such as copper, aluminum and other metals, and the second pen cap part 12 is made of insulating material, such as rubber, plastic and other non-metals. The first pen cap part 11 can be arranged at the upper end of the second pen cap part 12. Specifically, the pen cap is movably arranged on the main body, and the position of the pen cap relative to the main body can be changed by pressing or rotating the pen cap, thereby flexibly realizing switching between different antennas.

[0018] The body can be made of conductive material, and the pen cap divides the body into a first body part 21 and a second body part 22 which are arranged opposite to each other in the cross-sectional view, wherein the first body part 21 and the second body part 22 can be used as antenna components of the electronic pen.

[0019] When the pen cap is in the first position (e.g., unpressed), the first body portion 21 is electrically connected to the integrated circuit 30 as a radiation branch of the antenna, and the second body portion 22 is electrically connected to the ground terminal of the integrated circuit 30 to form a first antenna. Specifically, when the first antenna is working, a current path is formed on the surface of the first body portion 21, the integrated circuit 30, and the second body portion 22, thereby generating a resonant frequency and an operating frequency band. For example, when the resonant frequency and the operating frequency band of the first antenna meet WIFI2.4G or 5G communication, the first antenna can be used as a WIFI2.4G antenna or a 5G antenna.

[0020] When the pen cap is in the second position (for example, the pressed state), the first pen cap part 11 is electrically connected to the first body part 21 and the second body part 22, and the first pen cap part 11, the first body part 21 and the integrated circuit 30 form a single-band antenna, and the first pen cap part 11, the second body part 22 and the integrated circuit 30 form another single-band antenna, so that the electronic pen can use two single-band antennas with different working frequency bands to form a multi-band working antenna, that is, to form a second antenna. Specifically, when the second antenna is working, a current path is formed on the surface of the first pen cap part 11, the first body part 21 and the integrated circuit 30, so as to generate a resonant frequency and a working frequency band, and another current path is formed on the surface of the first pen cap part 11, the second body part 22 and the integrated circuit 30, so as to generate another resonant frequency and a working frequency band. The first body part 21 and the second body part 22 are electrically connected through the first pen cap part 11, so that the electronic pen can form a multi-band working antenna, so that the frequency band of the second antenna is widened, so as to meet the corresponding frequency band width of voice calls, that is, the antenna in this state can be used for voice calls.

[0021] In the embodiment of the present application, the first cap part 11 and the body of the electronic pen are made of conductive materials, and the second cap part 12 is made of insulating materials. By changing the different positions of the cap on the electronic pen body, different current paths are formed between the cap, the body and the integrated circuit 30, thereby forming working antennas of different frequencies and frequency bands, thereby realizing direct switching between the WIFI 2.4G or 5G antenna and the voice call antenna. Therefore, the electronic pen provided in the embodiment of the present application can solve the problem that the electronic pen can only cover a single frequency band and has a single function.

[0022] In a possible implementation, the first cap part 11 and the second cap part 12 may be of integrated design to facilitate assembly by staff.

[0023] In one possible implementation, Figure 2 The schematic diagram of the structure of the electronic pen provided by the embodiment of the present application shows that a slit 50 may be provided in the first body part 21 or the second body part 22 of the body, for example, Figure 2As shown, the slit 50 is opened in the second body part 22. When the pen cap is in the first position, the first body part 21 is electrically connected to the integrated circuit 30, and the second body part 22 is electrically connected to the ground terminal of the integrated circuit 30 through the slit 50 to form a parasitic unit of the first antenna. Specifically, a current path is formed on the surface of the first body part 21, the integrated circuit 30 and the second body part 22 having the slit 50. By opening the slit 50 in the second body part 22, the electronic pen can form an antenna with a higher operating frequency band, and then the electronic pen can realize the function of making voice calls with other network devices on the basis of realizing the WIFI2.4G or 5G Internet access function.

[0024] In another implementation, a slit 50 can be provided in both the first body portion 21 and the second body portion 22 of the body. When the pen cap is in the first position, the first body portion 21 is electrically connected to the integrated circuit 30 through the first slit, and the second body portion 22 is electrically connected to the ground terminal of the integrated circuit 30 through the second slit. Thus, the first antenna forms two parasitic units, so that the electronic pen can form an antenna that is more compatible with other network devices, thereby improving the quality of the Internet access function of the electronic pen.

[0025] Of course, in this implementation, the first body part 21 and the second body part 22 of the electronic pen may be provided with different numbers and sizes of gaps to form more parasitic units, thereby realizing different functions and meeting various needs of users.

[0026] In a possible implementation, the first body portion 21 can be electrically connected to the integrated circuit 30 through a metal sheet (not shown in the figure), and the metal sheet is arranged between the first body portion 21 and the integrated circuit 30, and the metal sheet is arranged at a position where the integrated circuit 30 is close to the second pen cap portion 12. The metal sheet plays a connecting role. Through this connection method, more parts of the first body portion 21 are indirectly electrically connected to the integrated circuit 30, thereby reducing the impedance between the first body portion 21 and the integrated circuit 30, and then increasing the frequency of the first antenna, so that the first antenna radiates or receives radio waves more effectively. Further, the second body portion 22 can also be electrically connected to the ground terminal of the integrated circuit 30 through the metal sheet.

[0027] In one possible implementation, when the pen cap is in the second position, the first main body portion 21, the first pen cap portion 11 and the second main body portion 22 can form a ring structure. The antenna formed by this structure is a loop antenna, that is, the second antenna is a loop (LOOP) antenna. Since the terminal load impedance of the LOOP antenna can be zero, the second antenna has a stronger ability to radiate or receive radio waves, thereby improving the quality of voice calls of the electronic pen.

[0028] In one possible implementation, the slit 50 is provided on the second body portion 22. When the pen cap is in the first position, the first antenna formed by the electrical connection between the first body portion 21 and the integrated circuit 30 can be used for WIFI connection, and the parasitic unit of the first antenna formed by the electrical connection between the second body portion 22 having the slit 50 and the ground end of the integrated circuit 30 can be used for voice calls. When the pen cap is in the second position, the first body portion 21, the first pen cap portion 11 and the second body portion 22 having the slit 50 can form a LOOP antenna, that is, the second antenna is a LOOP antenna, and the second antenna can be used for voice calls in other states.

[0029] In another implementation, a slit 50 can be provided in both the first body portion 21 and the second body portion 22 of the body. When the pen cap is in the second position, the first pen cap portion 11, the first body portion 21 with the slit 50, and the integrated circuit 30 are electrically connected to form a second antenna, and the first pen cap portion 11, the second body portion 22 with the slit 50 and the ground end of the integrated circuit 30 are electrically connected to form another second antenna. The two second antennas have different frequency bandwidths. When the user uses the electronic pen, the electronic pen can switch to a better second antenna according to the real-time voice call quality, thereby improving the user experience.

[0030] In one possible implementation, a nanobar 40 is placed horizontally inside the main body, and the main body is divided into an upper and lower part by the nanobar 40, wherein the nanobar 40 is an insulating material, and the main body is divided into a radiator and a non-radiator. The farther the position of the nanobar 40 is relative to the pen cap, the longer the antenna formed by the electronic pen, and the better the antenna's ability to receive or radiate radio waves.

[0031] In another implementation, the first body portion 21 and the second body portion 22 may be located above the nano-rods 40 .
