[0044] Unless otherwise defined, all technical terms used in the embodiments of the present utility model have the same meaning as commonly understood by those of ordinary skill in the art.

[0045] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0046] On the one hand, as shown in combination with Figure 1 and Figure 2 , this embodiment provides a wireless control device 100, and the wireless control device 100 includes: a housing 1, a circuit board module 2, and a battery 3.

[0047] The housing 1 is hollow, the circuit board module 2 and the battery 3 are respectively located inside the housing 1, and the battery 3 is electrically connected to the circuit board module 2; the wireless control device 100 further includes an antenna radiator 4, the antenna radiator 4 is located at the end of the housing 1, and the antenna radiator 4 is fed-connected to the circuit board module 2.

[0048] In the wireless control device 100 of this embodiment, the antenna radiator 4 is located at the end of the housing 1. The antenna radiator 4 is fed and connected to the circuit board module 2. On the one hand, the antenna radiator 4 can make full use of the better clearance environment at the end of the housing 1, so that the antenna radiator 4 has better working efficiency and is not easily blocked by being held. On the other hand, the antenna radiator 4 and the circuit board module 2 are arranged separately. After the two are fed and connected, they can be regarded as a dipole antenna, which can further improve the radiation performance of the antenna radiator 4, and thus can improve the wireless communication performance of the wireless control device 100.

[0049] In addition, the improvement of the working efficiency of the antenna radiator 4 is also beneficial to reducing the power consumption of wireless communication, reducing power consumption, and thus is beneficial to improving the battery life of the wireless control device 100.

[0050] In some possible implementation manners, the housing 1 may have different shapes, such as a pen tube shape, a cuboid shape, and so on. Among them, the end of the housing 1 may be the end of the housing 1 along the direction of the larger dimension. There are usually two ends of the housing 1, and the antenna radiator 4 is located inside one of the two ends.

[0051] Exemplarily, the antenna radiator 4 may have different shapes, such as a cylindrical shape, a rectangular shape, a spiral shape, and so on. The structure of the antenna radiator 4 may be a metal sheet, a metal foil, or an LDS (Laser-Direct-structuring) structure layer.

[0052] In some possible implementation manners, the circuit board module 2 includes a circuit board body and at least one electronic component integrated thereon. Among them, the circuit board body may be a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flexible board, and so on.

[0053] Combined Figure 1 As shown, in some embodiments, one end of the housing 1 is the pen tip 101, and the other end of the housing 1 is the pen tail 102; the antenna radiator 4 is located at the pen tail 102.

[0054] In this embodiment, one end of the housing 1 is the pen tip 101 and the other end is the pen tail 102. When the user holds and uses the antenna control device, the pen tip 101 is usually downward and the pen tail 102 is upward, and the palm holds the middle of the housing 1. Through the above arrangement, the antenna radiator 4 is arranged at the pen tail 102, which is not easily blocked by the palm and can avoid other electronic components in the antenna control device.

[0055] In some possible implementation manners, referring to Figure 1As shown, the pen tip 101 is provided with a pen tip device, which can be an elastic touch pen tip. Through this pen tip device, the user can perform touch operations, or perform digital writing, painting, etc. on the controlled device 200.

[0056] Combined with Figure 1 and Figure 2 As shown, in some embodiments, the battery 3 is located inside the pen tail 102, and the circuit board module 2 is located between the pen tip 101 and the pen tail 102.

[0057] In this embodiment, as the core component of the wireless control device 100, the circuit board module 2 needs to provide control signals to all the electronic components in the wireless control device 100. Therefore, it is required that the circuit board module 2 is electrically connected to all the electronic components respectively. If the circuit board module 2 is arranged at the pen tip 101 or the pen tail 102, it is difficult for the circuit board module 2 to achieve electrical connection with all the electronic components. At this time, only multiple circuit board modules 2 can be used, which will increase the cost and the process difficulty.

[0058] Therefore, it is selected to arrange the battery 3 at the pen tail 102 and the circuit board module 2 between the pen tip 101 and the pen tail 102. The circuit board module 2 is basically located in the middle of the two ends of the housing 1. The circuit board module 2 can be conveniently electrically connected to all the electronic components.

[0059] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the antenna radiator 4 is located on at least a part of the outer surface of the battery 3.

[0060] In this embodiment, considering the aspects of structural compactness and stacking difficulty, the antenna radiator 4 and the battery 3 are both arranged at the pen tail 102 of the housing 1. At this time, the antenna radiator 4 can be arranged on at least a part of the outer surface of the battery 3. The antenna radiator 4 can be bent or designed in a conformal shape such as a curved surface, so that the shape of the antenna radiator 4 is basically the same as that of the outer surface of the battery 3. After the two are combined and arranged at the pen tail 102 of the housing 1, the volume of the pen tail 102 will not be increased.

[0061] In addition, arranging the antenna radiator 4 on the outer surface of the battery 3 can reduce the interference generated by the metal components inside the battery 3.

[0062] In some possible implementation manners, the antenna radiator 4 is combined with the metal housing 1 on the outer surface of the battery 3, which can realize the reuse of the metal housing 1 on the outer surface of the battery 3, and is beneficial to reducing the product cost. Also, the antenna radiator 4 is closely electrically connected to the metal housing 1 of the battery 3 to form a conductive structure. The antenna radiator 4 and the metal housing 1 can simultaneously receive and transmit electromagnetic waves.

[0063] In some other possible implementation manners, an insulating layer is provided between the antenna radiator 4 and the metal housing 1 of the battery 3, and the antenna radiator 4 independently receives and emits electromagnetic waves.

[0064] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the battery 3 is cylindrical, the antenna radiator 4 is cylindrical, and the battery 3 is located inside the antenna radiator 4.

[0065] In this embodiment, using a cylindrical battery 3 can make full use of the internal space of the housing 1. The battery 3 has a larger volume, thus having a larger capacity, making the battery life of the wireless control device 100 stronger. On this basis, using a cylindrical antenna radiator 4 sleeved outside the battery 3 can also make full use of the internal space of the housing 1. The antenna radiator 4 has sufficient dimensions and better radiation performance.

[0066] In addition, the cylindrical antenna radiator 4 can provide better support and positioning for the battery 3, which is beneficial to improving the stacking efficiency and positioning accuracy of the antenna radiator 4 and the battery 3, improving the processing efficiency of the wireless control device 100, and reducing the processing cost.

[0067] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the antenna radiator 4 includes a feeding arm 41. The feeding arm 41 extends towards the circuit board module 2 and is electrically connected to the circuit board module 2.

[0068] Through the above arrangement, the antenna radiator 4 can use the feeding arm 41 to perform feeding connection with the circuit board module 2 to realize the reception and emission of electromagnetic waves.

[0069] Exemplarily, the feeding arm 41 and the antenna radiator 4 are of an integral structure, and the feeding arm 41 is formed by a part of the antenna radiator 4 extending outwards. Through the above arrangement, the feeding arm 41 and the antenna radiator 4 are of an integral structure, and the feeding arm 41 and the antenna radiator 4 are integrally processed. When using the feeding arm 41 to be electrically connected to the circuit board module 2, since the length of the feeding arm 41 is processed according to the target size, it can ensure that the electrical length from the solder joint (i.e., the feeding point) of the circuit board module 2 to the antenna radiator 4 meets the target length, so as to ensure that the antenna radiator 4 has radiation performance meeting the design requirements.

[0070] In addition, the length of the feeding arm 41 is basically equal to the distance between the antenna radiator 4 and the circuit board module 2, so that the feeding arm 41 can also improve the positioning efficiency and positioning accuracy between the antenna radiator 4 and the circuit board module 2.

[0071] Combined with Figure 3As shown, in some embodiments, the extension length of the antenna radiator 4 in the direction of the two ends of the housing 1 is L, where the value range of L is 15 - 20 mm. When the size L of the antenna radiator 4 satisfies the above value range, the antenna radiator 4 has good radiation performance and can meet the wireless communication between the wireless control device 100 and the controlled device 200. Exemplarily, when the housing 1 is in the shape of a pen tube, the direction of the two ends of the housing 1 can also be described as the axial direction of the housing 1.

[0072] Exemplarily, the value of the size L of the antenna radiator 4 can be, for example, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, and so on.

[0073] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the battery 3 and the circuit board module 2 are electrically connected through two power lines 31; an inductance element 32 is provided on each of the two power lines 31.

[0074] In this embodiment, the battery 3 is connected to the circuit board module 2 by two power lines 31, and the two power lines 31 are respectively connected to the positive and negative electrodes of the battery 3. When the battery 3 and the antenna radiator 4 are arranged close to each other, during the operation of the antenna radiator 4, the battery 3 and the circuit board module 2 can be regarded as two series-connected metal conductors and will respectively generate induced currents. If this induced current is not isolated, it will in turn interfere with the antenna radiator 4. At this time, by arranging the inductance element 32 on the power line 31 and using the working characteristic of the inductance element 32 to conduct direct current and block alternating current, the induced current is blocked so that it cannot flow between the battery 3 and the circuit board module 2, thereby reducing the interference of the induced current on the antenna radiator 4.

[0075] In some embodiments, the value range of the inductance value Q of the inductance element 32 is 30 - 100 nH. When the inductance value Q of the inductance element 32 satisfies the above value range, the inductance element 32 can have the best interference isolation effect. Moreover, the magnitude of the inductance value Q of the inductance element 32 will affect the position of the clutter of the antenna radiator 4. By adjusting the inductance value Q of the inductance element 32, the clutter of the antenna radiator 4 can be moved outside the target frequency band, thereby ensuring the radiation efficiency of the antenna radiator 4 in the target frequency band.

[0076] Combined with Figure 5 As shown, in some embodiments, the circuit board module 2 includes at least one of a nib control circuit 21 and a wireless charging circuit 22.

[0077] Exemplarily, the circuit board module 2 includes a nib control circuit 21. The nib control circuit 21 is located at the end of the circuit board module 2 close to the nib tip 101 and can be electrically connected to the nib assembly 11. The nib control circuit 21 can receive the signal feedback from the nib assembly 11 or input signals to the nib assembly 11, so as to realize the touch operation of the nib assembly 11 in the controlled device 200, or perform digital writing, painting, etc. Another exemplarily, the nib control circuit 21 may further include at least one control button 211, which can be a physical button or a touch button. At least one control button 211 can pass through the housing 1 and at least part of it is exposed outside the housing 1. The user can operate the wireless control device 100 or the controlled device 200 by pressing the at least one control button 211.

[0078] Another exemplarily, referring to Figure 5 , the circuit board module 2 includes a wireless charging circuit 22. The wireless charging circuit 22 is electrically connected to the battery 3, and the battery 3 can be wirelessly charged by using the wireless charging circuit 22. Wherein, the wireless charging circuit 22 may include a charging chip 221 and a charging coil 222, and the charging chip 221 and the charging coil 222 can be respectively arranged on the two side surfaces of the circuit board module 2.

[0079] Yet another exemplarily, referring to Figure 5 , the circuit board module 2 further includes a radio frequency circuit 23. The radio frequency circuit 23 is electrically connected to the feeding arm 41 of the antenna radiator 4, and the radio frequency circuit 23 can provide an excitation signal to the feeding arm 41 for feeding the antenna radiator 4.

[0080] In some embodiments, the wireless control device 100 is a Bluetooth pen, and the antenna radiator 4 operates in the Bluetooth communication frequency band. The wireless control device 100 of this embodiment can operate in the Bluetooth communication frequency band and be used as a Bluetooth pen to meet the functions of digital writing, painting, and wireless control, etc.

[0081] On the other hand, as shown in Figure 6 , this embodiment provides an electronic device, which includes the wireless control device 100 of the present invention and a controlled device 200 communicatively connected to the wireless control device 100.

[0082] The electronic device of this embodiment adopts the wireless control device 100 of the present invention and has all the beneficial technical effects of all the embodiments herein.

[0083] The controlled device 200 of this embodiment includes portable terminal devices, such as: smart phones, tablet computers, laptop computers or desktop computers, etc.

[0084] In some possible implementations, the controlled device 200 includes a display unit 2001. The display unit 2001 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the terminal device. These graphical user interfaces can be composed of graphics, text, icons, videos, and any combination thereof.

[0085] The display unit 2001 may include a display panel and a touch-sensitive surface covering the display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. The touch operation can be performed on the touch-sensitive surface using the pen tip assembly 11. When the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor to determine the type of touch event. Subsequently, the processor provides a corresponding visual output on the display panel according to the type of touch event.

[0086] In some possible implementations, the controlled device 200 is built-in with a wireless communication module, and the wireless communication module can be used to establish a wireless communication connection with the wireless control device 100.
