In addition, the distance between the second fixing hole and the main body part is closer, and the cooperation area between the main body part and the bracket is larger. Therefore, the probability of the main body part displacing relative to the bracket is relatively higher than that of the plug-in part. By shortening the distance between the second fixing hole and the main body part, the relative position reliability between the main body part and the bracket can be improved, and further the probability of relative displacement between the circuit board and the bracket can be effectively reduced.

[0044] In the description of the present utility model, "a plurality of" means two or more. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0045] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0046] In the related art, an electronic pen is provided with a circuit board connected to a battery, and a USB is plugged into the circuit board for charging the battery. The electronic pen usually has two brackets for clamping the circuit board. However, the two brackets need to be processed separately, and during the assembly process, the two brackets need to be connected. The production steps of the electronic pen are numerous, the connection strength between the two brackets is low, and there is an assembly error between the two brackets. Therefore, the installation accuracy of the circuit board is low, and the probability of damage when connected to the USB is high.

[0047] The following combines Figures 1 to 10 , to describe the embodiments of the present utility model.

[0048] According to an embodiment of the present utility model, an electronic pen 1 is provided. The electronic pen 1 includes a pen case 100, a bracket 200, a circuit board 300, and an energy storage component (not shown in the figure). Among them, the electronic pen 1 can be used in combination with terminal products such as a notebook computer, a tablet computer, a desktop computer, and a mobile phone.

[0049] The pen case 100 is provided with a charging port 101 on its peripheral wall. The bracket 200 is disposed inside the pen case 100. The bracket 200 is provided with an installation slot 210 and a charging slot 220. The installation slot 210 and the charging slot 220 are communicated. The installation slot 210 is located on the side of the bracket 200 facing away from the charging port 101, and the charging slot 220 is located on the side of the bracket 200 facing the charging port 101. The position of the charging slot 220 is correspondingly set with the charging port 101. The circuit board 300 (Printed Circuit Board, PCB) is disposed in the installation slot 210. The circuit board 300 includes a charging portion 330. The charging portion 330 is located in the charging slot 220. The energy storage component is disposed inside the pen case 100 and is electrically connected to the circuit board 300. Among them, the energy storage component can be a rechargeable battery for supplying power to the electronic devices in the electronic pen 1.

[0050] For the electronic pen 1 according to the embodiment of the present utility model, the charging structure 2 can be inserted into the charging slot 220 through the charging port 101, and then the charging structure 2 contacts and is electrically connected to the charging part 330. The charging structure 2 charges the energy storage component through the circuit board 300. The electronic pen 1 can achieve the charging function without the need for terminals of a separate patch-type wireless charger, etc., reducing the patching process, shortening the production time cycle, reducing the material cost, and improving the production efficiency and production capacity.

[0051] For example, the charging structure 2 can be a plug such as a USB (Universal Serial Bus) plug that can be used for charging. The charging part 330 can be provided with a bare copper structure, that is, the charging part 330 is constructed with a "gold finger" structure, and the bare copper structure is used to cooperate with the charging structure 2 to achieve electrical connection. And by adjusting the thickness of the charging part 330, different durable plugging requirements can be met.

[0052] In addition, by cooperating the charging part 330 with an external terminal, the OTA (Over-the-Air Technology) upgrade function can also be realized, which is used to update the control system of the electronic pen 1. The circuit board 300 integrates multiple functions, which is beneficial to improving the applicability of the electronic pen 1.

[0053] In addition, the circuit board 300 is inserted into the installation slot 210 along the radial direction of the electronic pen 1, the charging part 330 is located in the charging slot 220, the bracket 200 is installed in the pen case 100, and the inner peripheral wall of the pen case 100 can play a limiting role on the circuit board 300 in its radial direction, preventing the circuit board 300 from detaching from the installation slot 210, so as to ensure that the charging part 330 is stably located in the charging slot 220, ensuring the effective realization of the charging function. And the bracket 200 is an integral structure, the bracket 200 does not need to be separately arranged, the processing is simpler, and the structural strength of the bracket 200 is higher, the limiting effect on the circuit board 300 is better, and there is no need to additionally arrange a structure for closing the installation slot 210, that is, the reliability of the relative position between the circuit board 300 and the bracket 200 can be ensured, the structure is simple, the disassembly and assembly are convenient, and the number of parts is reduced.

[0054] And the circuit board 300 is inserted into the installation slot 210 along the radial direction of the electronic pen 1, which can make the charging part 330 face the peripheral wall of the pen case 100. Furthermore, the charging port 101 is arranged on the peripheral wall of the pen case 100. Compared with having a charging port at the end of the pen case, the space on the peripheral wall of the pen case 100 is larger, the size of the charging port 101 can be larger, the plugging and unplugging of the charging structure 2 is convenient, which is conducive to guiding the electrical connection between the charging structure 2 and the circuit board 300, and avoiding the collision between the charging structure 2 and the pen case 100 due to the too small size of the charging port 101, which is beneficial to extending the service life of the charging port 101.

[0055] Such asFigure 8 As shown, in the technical solution of this embodiment, the circuit board 300 and the charging part 330 are of an integrally formed structure. In this way, there is no need for welding or bonding between the circuit board 300 and the charging part 330, the connection reliability between the circuit board 300 and the charging part 330 is high, the manufacturing is simpler, and it is beneficial to reduce the resistivity between the circuit board 300 and the charging part 330, reduce the heat generation, and improve the charging efficiency.

[0056] As Figure 2 , Figure 8 and Figure 10 As shown in, in the technical solution of this embodiment, the installation slot 210 includes an axial section 211 and a plurality of radial sections 212. The axial section 211 extends along the axial direction of the electronic pen 1 and communicates with the charging slot 220. Each radial section 212 extends along the radial direction of the electronic pen 1 and communicates with the axial section 211. The charging slot 220 and the plurality of radial sections 212 are arranged at intervals along the axial direction of the electronic pen 1, and the charging slot 220 and the plurality of radial sections 212 are located on the same side of the axial section 211.

[0057] The circuit board 300 further includes a main body part 310 and a plurality of plug-in parts 320. The charging part 330 and the plurality of plug-in parts 320 are both connected to the main body part 310. The main body part 310 is located within the axial section 211, and the plurality of plug-in parts 320 are respectively inserted into the plurality of radial sections 212 one by one. That is to say, the charging part 330 and the plurality of plug-in parts 320 are located on the same side of the main body part 310, and the charging part 330 and the plurality of plug-in parts 320 are arranged at intervals along the axial direction of the electronic pen 1.

[0058] By arranging the cooperation of the plurality of radial sections 212 and the plurality of plug-in parts 320, the relative positions of the bracket 200 and the circuit board 300 in the axial direction of the electronic pen 1 can be fixed, the contact area between the bracket 200 and the circuit board 300 can be increased, and the relative position stability between the bracket 200 and the circuit board 300 can be improved.

[0059] Moreover, since the charging slot 220 and the plurality of radial sections 212 are located on the same side of the axial section 211, and the charging part 330 and the plurality of plug-in parts 320 are located on the same side of the main body part 310, in this way, when the circuit board 300 approaches the bracket 200 along the radial direction of the electronic pen 1, the cooperation between the plug-in parts 320 and the radial sections 212, as well as the cooperation between the charging part 330 and the charging slot 220 can be simultaneously achieved. When the circuit board 300 moves away from the bracket 200 along the radial direction of the electronic pen 1, the separation between the plug-in parts 320 and the radial sections 212, as well as the separation between the charging part 330 and the charging slot 220 can be simultaneously achieved. The disassembly and assembly between the circuit board 300 and the bracket 200 are more convenient.

[0060] As Figure 2 , Figure 5 , Figure 6 ,Figures 8 - 10 As shown, in the technical solution of this embodiment, the bracket 200 is provided with at least two first fixing holes 201. One end of at least two plugging parts 320 connected to the main body part 310 is provided with second fixing holes 321. The at least two first fixing holes 201 and the at least two second fixing holes 321 are arranged in one-to-one correspondence. The electronic pen 1 further includes a fixing component 400. The fixing component 400 includes at least two fixing parts 410. Each fixing part 410 passes through a first fixing hole 201 and the second fixing hole 321 corresponding to the first fixing hole 201.

[0061] By arranging the fixing part 410 to pass through the first fixing hole 201 and the second fixing hole 321 at the same time, the reliability of the relative position between the bracket 200 and the circuit board 300 is further improved, and the connection reliability between the charging structure 2 and the charging part 330 is improved, which is beneficial to ensuring the charging efficiency, and can avoid the charging part 330 shaking in the charging slot 220, prevent the alignment difficulty and collision between the charging structure 2 and the charging part 330, reduce the damage probability of the charging part 330, and extend the service life of the electronic pen 1.

[0062] In addition, the second fixing hole 321 is arranged at one end of the plugging part 320 connected to the main body part 310. That is to say, the distance between the second fixing hole 321 and the main body part 310 is closer, and the matching area between the main body part 310 and the bracket 200 is larger. Therefore, the probability of the displacement of the main body part 310 relative to the bracket 200 is relatively higher than that of the plugging part 320. By shortening the distance between the second fixing hole 321 and the main body part 310, the reliability of the relative position between the main body part 310 and the bracket 200 can be improved, and further the probability of the relative displacement between the circuit board 300 and the bracket 200 can be effectively reduced.

[0063] In the technical solution of this embodiment, the fixing part 410 may include a connecting rubber part. In this way, the relative position between the bracket 200 and the circuit board 300 is fixed by the connecting rubber, and the relative position between the bracket 200 and the circuit board 300 is more stable, and the installation is convenient.

[0064] As Figure 6 shown, in the technical solution of this embodiment, the first fixing hole 201 is in threaded fit with the fixing part 410. Among them, the fixing part 410 may be a screw or a bolt. In this way, the fixed connection between the fixing part 410 and the bracket 200 is convenient for disassembly and assembly, reduces the assembly difficulty, and improves the production efficiency.

[0065] As Figure 6 and Figure 9As shown, in the technical solution of this embodiment, the fixing component 400 further includes a fixing plate 420. Each fixing member 410 is connected to the fixing plate 420. A positioning groove 230 is provided on the outer peripheral surface of the bracket 200, and the fixing plate 420 is disposed in the positioning groove 230. Wherein, the fixing plate 420 and the fixing member 410 can be an integrally formed structure.

[0066] By disposing the fixing plate 420 in the positioning groove 230 and inserting the fixing member 410 into the first fixing hole 201 and the second fixing hole 321, the cooperation among the fixing component 400, the bracket 200, and the circuit board 300 is convenient. Moreover, the relative positions of the two fixing members 410 are fixed by the fixing plate 420, which is beneficial to ensuring the relative positions between the two fixing members 410, and the fixing members 410 are not easily lost during disassembly and assembly.

[0067] Wherein, the fixing member 410 can include a first section 411, a second section 412, and a third section 413. The first section 411 is connected to the fixing plate 420, the second section 412 is connected between the first section 411 and the third section 413, the diameter of the first section 411 is greater than the diameter of the second section 412, and the diameter of the second section 412 is greater than the diameter of the third section 413.

[0068] The second section 412 cooperates with the second fixing hole 321 on the circuit board 300. The first fixing hole 201 includes a first hole section and a second hole section. The first hole section is located between the circuit board 300 and the fixing plate 420, and the second hole section is located on the side of the circuit board 300 facing away from the fixing plate 420. The diameter of the first hole section is greater than the diameter of the second hole section. When the fixing member 410 passes through the first fixing hole 201 and the second fixing hole 321, the first section 411 cooperates with the first hole section, and the third section 413 cooperates with the second hole section.

[0069] In this way, the relative positioning between the fixing component 400 and the bracket 200 is more reliable.

[0070] For example, the connecting glue can be used simultaneously with screws, bolts, and the fixing plate 420. The connecting glue is disposed in the first fixing hole 201. At this time, the connecting glue can flow into the second fixing hole 321. And after the threaded member is inserted into the first fixing hole 201 and the second fixing hole 321, the connecting glue is disposed in the first fixing hole 201 again to prevent the fixing member 410 from being unable to be inserted into the first fixing hole 201 after the connecting glue is cured;

[0071] Or, the connecting glue is disposed at one end of at least two radial sections 212 away from the axial section 211. Since the second fixing hole 321 is disposed at one end where the plugging portion 320 is connected to the main body portion 310, the connecting glue is disposed at one end of the radial section 212 away from the axial section 211. In this way, both ends of the radial section 212 in the radial direction of the electronic pen 1 are fixedly connected to the bracket 200, greatly increasing the connection strength between the circuit board 300 and the bracket 200;

[0072] Alternatively, the connecting glue is disposed in the first fixing hole 201, and at the same time, the connecting glue is disposed at one end of at least two radial segments 212 away from the axial segment 211. In this way, the relative position between the circuit board 300 and the bracket 200 is more stable.

[0073] Such as Figure 8 As shown, in the technical solution of this embodiment, one end of the charging part 330 away from the main body part 310 extends beyond one end of the plugging part 320 away from the main body part 310. Among them, one end of the charging part 330 away from the main body part 310 does not extend beyond the outer peripheral surface of the bracket 200, so as to avoid collision between the charging part 330 and the pen shell 100 when the bracket 200 is inserted into the pen shell 100.

[0074] In this way, the size of the charging part 330 in the radial direction of the electronic pen 1 is larger than the size of the plugging part 320 in the radial direction of the electronic pen 1. When the charging structure 2 is inserted into the charging slot 220, the contact between the charging structure 2 and the charging part 330 is faster, which is beneficial to ensuring reliable connection between the charging structure 2 and the charging part 330, and the charging effect is better.

[0075] Such as Figure 8 As shown, in the technical solution of this embodiment, a plurality of plugging parts 320 are arranged on opposite sides of the charging part 330 in the axial direction of the electronic pen 1. For example, the plurality of plugging parts 320 include a first plugging part 320 and a second plugging part 320. The first plugging part 320 and the second plugging part 320 are arranged adjacent to each other, and the charging part 330 is located between the first plugging part 320 and the second plugging part 320 in the axial direction of the electronic pen 1.

[0076] In this way, there are plugging parts 320 on both opposite sides of the charging part 330 in the axial direction of the electronic pen 1. The charging part 330 is relatively fixed to the bracket 200 by the plugging parts 320 on both opposite sides of the charging part 330 in the axial direction of the electronic pen 1, further reducing the shaking of the charging part 330 relative to the bracket 200, which is beneficial to improving the cooperation effect between the charging part 330 and the charging structure 2.

[0077] Such as Figure 2 、 Figure 7 、 Figure 8 And Figure 10 As shown, in the technical solution of this embodiment, the electronic pen 1 further includes a flexible circuit board 500 (Flexible Printed Circuit, FPC). The flexible circuit board 500 includes a first board body 510 and a second board body 520. The first board body 510 is located in the installation slot 210, the first board body 510 is stacked and connected with the circuit board 300, and the second board body 520 is located outside the bracket 200. The second board body 520 is connected with the first board body 510 and the energy storage component.

[0078] By providing a flexible circuit board 500, the flexible circuit board 500 can be deformed, and it can change its own shape according to the arrangement of components inside the pen housing 100, facilitating the connection between the circuit board 300 and the energy storage component, and also making the layout of the electronic pen 1 more convenient.

[0079] In addition, since the first plate body 510 is located in the installation slot 210 and the first plate body 510 and the circuit board 300 are stacked, the slot wall of the installation slot 210 can limit the first plate body 510 and the circuit board 300, fixing the relative positions between the first plate body 510 and the circuit board 300, and effectively reducing the probability of separation between the first plate body 510 and the circuit board 300.

[0080] As Figure 2 、 Figure 8 and Figure 10 shown, in the technical solution of this embodiment, the plurality of radial segments 212 include a preset radial segment 212, and the preset radial segment 212 is closer to the flexible circuit board 500 than other radial segments 212, and one side of the preset radial segment 212 facing the flexible circuit board 500 is open.

[0081] Specifically, the circuit board 300, the flexible circuit board 500, and the energy storage component can be arranged in sequence along the axial direction of the electronic pen 1. The circuit board 300 is closer to the pen tip, and the energy storage component is closer to the pen tip. The flexible circuit board 500 is located between the circuit board 300 and the energy storage component. Therefore, the radial segment 212 closest to the pen tip among the plurality of radial segments 212 is the preset radial segment 212, and one side of the preset radial segment 212 close to the comparison is open, facilitating the insertion of the flexible circuit board 500 into the preset radial segment 212 through the open part of the preset radial segment 212 to cooperate with the circuit board 300.

[0082] As Figure 2 、 Figure 8 and Figure 10 shown, in the technical solution of this embodiment, the cross-sectional area of the insertion portion 320 located in the preset radial segment 212 is larger than that of the other insertion portions 320. In this way, the insertion portion 320 located in the preset radial segment 212 has a larger area to cooperate with the flexible circuit board 500, which is beneficial to increasing the cooperation area between the circuit board 300 and the flexible circuit board 500, having a low resistivity at the connection between the circuit board 300 and the flexible circuit board 500, a large connection strength between the circuit board 300 and the flexible circuit board 500, and being more convenient for welding between the circuit board 300 and the flexible circuit board 500.

[0083] As Figure 4As shown, in the technical solution of this embodiment, the outer peripheral surface of the bracket 200 includes a first plane 202, the charging slot 220 is provided on the first plane 202, a second plane 102 is provided on the inner peripheral surface of the pen case 100, the charging port 101 penetrates through the second plane 102, and the first plane 202 and the second plane 102 are arranged in cooperation.

[0084] In this way, not only can the relative rotation between the bracket 200 and the pen case 100 be prevented, but also the alignment between the charging slot 220 and the charging port 101 can be effectively ensured, so as to ensure the convenient cooperation between the charging structure 2 and the charging part 330. Setting the charging slot 220 and the charging port 101 on a plane is also more convenient for processing.

[0085] For example, there can be multiple first planes 202, and the multiple first planes 202 are arranged at intervals along the circumferential direction of the bracket 200, and the charging slot 220 is provided on one of the first planes 202. There can be multiple second planes 102, and the multiple second planes 102 are arranged at intervals along the circumferential direction of the pen case 100, and the charging port 101 is provided on one of the second planes 102. In this way, the relative positions of the bracket 200 and the pen case 100 in the circumferential direction of the electronic pen 1 are more reliable.

[0086] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
