[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0050] like Figures 1 to 13 As shown, an embodiment of the present invention provides an electronic pen, which includes:

[0051] The pen body 1 is a shell structure with an assembly cavity. The pen body 1 has an opening 11 at an end in a first direction, wherein the first direction is an axial direction of the pen body 1 .

[0052] The pen cap 2 is detachably connected to the opening 11 , and the pen cap 2 at least partially extends out of the opening 11 .

[0053] The power supply component 3 is installed in the assembly cavity. The power supply component 3 includes a battery 31, a mounting bracket 33 and a main board 32. The first end of the battery 31 is detachably connected to the mounting bracket 33, the second end of the battery 31 and the pen cap 2 are detachably connected, and the main board 32 is installed on the mounting bracket 33, wherein the first end and the second end are two opposite ends of the battery 31 in the first direction.

[0054] A positive electrode connector 321 and a negative electrode connector 322 are connected to the main board 32 . The positive electrode connector 321 abuts against the positive electrode of the battery 31 , and the negative electrode connector 322 abuts against the negative electrode of the battery 31 .

[0055] It can be seen from the above embodiments that in the embodiments of the present application, since the first end of the battery 31 is detachably connected to the mounting bracket 33, the second end of the battery 31 and the pen cap 2 are detachably connected, the main board 32 is mounted on the mounting bracket 33, and the main board 32 is connected with a positive connector 321 and a negative connector 322. The positive connector 321 abuts against the positive pole of the battery 31, and the negative connector 322 abuts against the negative pole of the battery 31. Therefore, when the battery 31 needs to be replaced, the pen cap 2 can be removed from the opening 11 of the pen body 1, and then the first end of the battery 31 and the mounting bracket 33 are disassembled, and finally the second end of the battery 31 and the pen cap 2 are separated, so that the battery 31 can be disassembled. When assembling the battery 31 into the electronic pen, the second end of the battery 31 can be connected to the pen cap 2 first, and then the second end of the battery 31 can be connected to the mounting bracket 33, and at the same time, the positive electrode connector 321 can be abutted against the positive electrode of the battery 31, and the negative electrode connector 322 can be abutted against the negative electrode of the battery 31, and then the pen cap 2 can be connected to the opening 11. In summary, the electronic pen provided by the embodiment of the present invention can facilitate the disassembly and assembly of the battery 31, which is conducive to improving the endurance of the electronic pen and the service life of the electronic pen.

[0056] Among them, in the above embodiment, the pen body 1 can be a cylindrical shell structure, or a square shell structure, or a shell structure of other shapes, and the embodiment of the present application does not limit this. The pen body 11 has an opening 11 at the end of the first direction, which can be understood as the pen body 1 is a cylindrical structure with a single-end opening 11, or the tail of the pen body 1 has an opening 11. It should be noted that in the embodiment of the present application, the first direction can be understood as the axial direction of the pen body 1, that is, the extension direction of the axis. The specific first direction can be as follows: Figure 3 and Fig.10 The direction is shown by the X in the figure.

[0057] It should be noted that in the embodiment of the present application, the positive connector 321 and the negative connector 322 on the main board 32 can be any type of electrical connector that can conduct electricity, the positive connector 321 can be welded to the positive welding point of the main board 32, and the negative connector 322 can be welded to the negative welding point of the main board 32.

[0058] In addition, in the embodiment of the present application, the mounting bracket 33 is mainly a frame-shaped structure for fixing and mounting the mainboard 32. The mounting bracket 33 includes at least a plate-shaped fixing member, thereby providing sufficient installation space for the mainboard 32. At the same time, the end of the mounting bracket 33 facing the opening 11 can be used to connect with the first end of the battery 31. The connection method between the end of the mounting bracket 33 facing the opening 11 and the first end of the battery 31 can be any of the detachable connection methods such as snap connection, plug connection, and sleeve connection, or the first end of the battery 31 can be directly pressed against the end of the mounting bracket 33 facing the opening 11, which is not limited in the embodiment of the present application. The pen cap 2 at least includes a pressing member including a pressing portion 21 and a connecting portion 22. Exemplarily, the pressing portion 21 may be a pressing sheet, and the connecting portion 22 may be a pressing rod. The pressing sheet is fixed to the end of the pressing rod. The portion of the pen cap 2 that is connected to the second end of the battery 31 is the connecting portion 22. The connection method between the connecting portion 22 and the second end of the battery 31 may be any one of detachable connection methods such as snap-on, plug-in, and sleeve-type connection. The second end of the battery 31 may also be directly pressed against the end face of the connecting portion 22. The embodiment of the present application does not limit this.

[0059] The connection method of connecting the battery 31 to the mounting bracket 33 and the pen cap 2 can be that the battery 31 is inserted between the mounting bracket 33 and the pen cap 2, or the battery 31 is abutted between the mounting bracket 33 and the pen cap 2, or fixed between the mounting bracket 33 and the pen cap 2 by other detachable methods, which is not limited in the embodiment of the present application. The following will take the battery 31 inserted between the mounting bracket 33 and the pen cap 2 and the battery 31 abutted between the mounting bracket 33 and the pen cap 2 as examples for description, as follows:

[0060] In one possible implementation, Figures 1 to 7 As shown, in some embodiments, the pen cap 2 includes a pressing portion 21 and a connecting portion 22; the pressing portion 21 extends out of the opening 11, and the connecting portion 22 includes a first clamping arm 221 and a second clamping arm 222 arranged opposite to each other along the second direction, and the first clamping arm 221 and the second clamping arm 222 form an insertion cavity; the second end of the battery 31 is inserted into the insertion cavity, wherein the second direction intersects with the first direction.

[0061] In this embodiment, the pressing part 21 may be a component for providing grip and pressing, and the pressing part 21 may be a sheet-like structure, a plate-like structure, or a structure of other shapes. The first clamping arm 221 and the second clamping arm 222 included in the connecting part 22 both extend in the first direction. Exemplarily, the connecting part 22 may be a cylindrical structure, in which a through slot extending to the end along the first direction is provided, and the first clamping arm 221 and the second clamping arm 222 are formed by the through slot, so that a plug-in cavity is formed between the first clamping arm 221 and the second clamping arm 222. In this way, since the first clamping arm 221 and the second clamping arm 222 form a plug-in cavity, the second end of the battery 31 is plugged into the plug-in cavity. Therefore, when the pen cap 2 is taken out from the mouth of the pen body 1, it is only necessary to pull out the battery 31 from the plug-in cavity, which facilitates the separation between the battery 31 and the pen cap 2. It should be noted that the surface of the first clamping arm 221 facing the second clamping arm 222 and the surface of the second clamping arm 222 facing the first clamping arm 221 can be curved surfaces, thereby increasing the contact area between the first clamping arm 221 and the surface of the battery 31 and increasing the contact area between the second clamping arm 222 and the surface of the battery 31.

[0062] In some embodiments, the pen cap 2 also includes a first elastic member 23; the first elastic member 23 includes a first waterproof portion 231 and a first buffer portion 232, the first waterproof portion 231 is embedded in the outer wall of the pen cap 2 at a first position, the first position is the position of the connection portion between the pressing portion 21 and the connecting portion 22, the first buffer portion 232 extends into the plug-in cavity, and the first buffer portion 232 abuts against the end of the second end of the battery 31.

[0063] In this embodiment, the first elastic member 23 can be any one of chloroprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, polyisobutylene and polyurethane, etc., which is not limited in the embodiment of the present application. The first waterproof portion 231 included in the first elastic member 23 can be an annular structure, so that the first waterproof portion 231 can be sleeved on the outer wall of the connecting portion between the pressing portion 21 and the connecting portion 22. For example, an embedding groove can be provided on the outer wall of the connecting portion between the pressing portion 21 and the connecting portion 22, so that the first waterproof portion 231 is embedded in the embedding groove. The first buffer portion 232 included in the first elastic member 23 can be a block structure, a frame structure, or other shapes, which is not limited in the embodiment of the present application. The first buffer portion 232 extends into the plug-in cavity, so that a part of the first buffer portion 232 can be located between the first clamping arm 221 and the second clamping arm 222, and the overall strength of the pen cap 2 is improved by setting the first buffer portion 232. In this way, since the first waterproof part 231 is embedded in the outer wall at the first position of the pen cap 2, the first position is the position of the connection part between the pressing part 21 and the connecting part 22, the first buffer part 232 extends into the plug-in cavity, and the first buffer part 232 abuts against the end of the second end of the battery 31, the first waterproof part 231 can be located in the gap between the pen cap 2 and the pen body 1, thereby preventing external pollutants such as water vapor from entering the interior of the electronic pen, thereby improving the waterproof performance of the electronic pen, and at the same time, the first buffer part 232 can provide a buffer for the second end of the battery 31, thereby ensuring the stability of the electrical connection between the battery 31 and the main board 32, and ensuring that the battery 31 has no abnormal sound.

[0064] In some embodiments, the end of the mounting bracket 33 facing the pen cap 2 includes a third clamping arm 331 and a fourth clamping arm 332 arranged opposite to each other along the second direction, and the third clamping arm 331 and the fourth clamping arm 332 form a clamping cavity, and the first end of the battery 31 is clamped in the clamping cavity.

[0065] In this embodiment, the third clamping arm 331 and the fourth clamping arm 332 both extend in the first direction. Exemplarily, the end of the mounting bracket 33 facing the pen cap 2 may be a cylindrical structure, on which a through slot extending in the first direction is provided, and the third clamping arm 331 and the fourth clamping arm 332 are separated by the through slot, so that a clamping cavity is formed between the third clamping arm 331 and the fourth clamping arm 332. In this way, since the third clamping arm 331 and the fourth clamping arm 332 form a clamping cavity, the first end of the battery 31 is clamped in the clamping cavity, so that it is convenient to insert the first end of the battery 31 into the clamping cavity and to pull the battery 31 out of the clamping cavity. Similarly, similar to the first clamping arm 221 and the second clamping arm 222, the surface of the third clamping arm 331 facing the fourth clamping arm 332 and the surface of the fourth clamping arm 332 facing the third clamping arm 331 can be curved surfaces, thereby increasing the contact area between the third clamping arm 331 and the surface of the battery 31, and increasing the contact area between the fourth clamping arm 332 and the surface of the battery 31.

[0066] In some embodiments, a limiting groove 311 is provided on the surface of the second end of the battery 31, a first limiting protrusion 2211 is provided on the inner wall of the first clamping arm 221 facing the second clamping arm 222, and a second limiting protrusion is provided on the inner wall of the second clamping arm 222 facing the first clamping arm 221, and both the first limiting protrusion 2211 and the second limiting protrusion are clamped in the limiting groove 311.

[0067] In this embodiment, since a limiting groove 311 is provided on the surface of the second end of the battery 31, a first limiting protrusion 2211 is provided on the inner wall of the first clamping arm 221 facing the second clamping arm 222, and a second limiting protrusion is provided on the inner wall of the second clamping arm 222 facing the first clamping arm 221. Both the first limiting protrusion 2211 and the second limiting protrusion are clamped in the limiting groove 311. Therefore, the stability of the connection between the battery 31 and the pen cap 2 can be improved through the cooperation between the first limiting protrusion 2211 and the limiting groove 311, and the cooperation between the second limiting protrusion and the limiting groove 311.

[0068] In another possible implementation, Figures 8 to 12 As shown, in some embodiments, the pen cap 2 includes a pressing cap 24 and a connecting frame 25 , the pressing cap 24 extends out of the opening 11 , and the second end of the battery 31 abuts against the end of the connecting frame 25 away from the opening 11 .

[0069] In this embodiment, since the pen cap 2 includes a pressing cap 24 and a connecting frame 25, the pressing cap 24 extends out of the opening 11, and the second end of the battery 31 abuts against the end of the connecting frame 25 away from the opening 11. Therefore, when the pen cap 2 and the pen body 1 are separated, the pen cap 2 and the battery 31 can be separated, which facilitates the disassembly of the battery 31.

[0070] In some embodiments, the pen cap 2 also includes a second elastic member 26, the second elastic member 26 includes a second waterproof portion 261 and a second buffer portion 262, the second waterproof portion 261 is embedded in the outer wall of the second position of the pen cap 2, the second position is the position of the connection portion between the pressing cap 24 and the connecting frame 25, the second buffer portion 262 is nested on the outer wall of the connecting frame 25, and extends to the end of the connecting frame 25 away from the pressing cap 24, and the second buffer portion 262 abuts against the end face of the second end of the battery 31.

[0071] In this embodiment, the second elastic member 26 can be any one of chloroprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, polyisobutylene and polyurethane, etc., which is not limited in the present embodiment. The second waterproof portion 261 included in the second elastic member 26 can be an annular structure, so that the second waterproof portion 261 can be sleeved on the outer wall of the second position of the pen cap 2, and the second position is the position of the connection between the pressing cap 24 and the connecting frame 25. For example, an embedding groove can be provided on the outer wall of the connection between the pressing portion 21 and the connecting portion 22, so that the second waterproof portion 261 is embedded in the embedding groove. The second buffer portion 262 can be a cylindrical structure, a frame-shaped structure, or a structure of other shapes. In this way, since the second waterproof portion 261 is embedded in the outer wall of the second position of the pen cap 2, the second position is the position of the connection portion between the pressing cap 24 and the connecting frame 25, the second buffer portion 262 is nested in the outer wall of the connecting frame 25 and extends to the end of the connecting frame 25 away from the pressing cap 24. The second buffer portion 262 abuts against the end face of the second end of the battery 31. Therefore, the second waterproof portion 261 can be located in the gap between the pen cap 2 and the pen body 1, thereby preventing external pollutants such as water vapor from entering the interior of the electronic pen, thereby improving the waterproof performance of the electronic pen. At the same time, the second buffer portion 262 provides a buffer for the second end of the battery 31, thereby ensuring the stability of the electrical connection between the battery 31 and the main board 32, ensuring that the battery 31 has no abnormal sound, and the second buffer portion 262 can provide an elastic force for the pen cap 2 to abut the second end of the battery 31, thereby ensuring the stability of the pen cap 2 after abutting the second end of the battery 31. It should be noted that, since the second buffer portion 262 is nested on the outer wall of the connecting frame 25 , the second buffer portion 262 can increase the overall strength of the pen cap 2 and further enhance the waterproof performance of the connecting frame 25 .

[0072] In some embodiments, the end of the mounting bracket 33 facing the pen cap 2 includes a pressing surface, and the first end of the battery 31 abuts against the pressing surface.

[0073] In this embodiment, since the end of the mounting bracket 33 facing the pen cap 2 includes a pressing surface, the first end of the battery 31 abuts on the pressing surface, and the second end of the battery 31 abuts on the end of the connecting frame 25 away from the opening 11, the battery 31 is abutted between the pen cap 2 and the mounting bracket 33, that is, the installation and fixation of the battery 31 are achieved through the positioning of the mounting bracket 33 and the pen cap 2, and there is no connecting part between the battery 31 and the mounting bracket 33, and there is no connecting part between the battery 31 and the pen cap 2. In this way, when removing the battery 31, it is only necessary to separate the pen cap 2 from the pen body 1, that is, the pen cap 2 and the battery 31 can be separated, which is convenient for the disassembly of the battery 31, and at the same time, there is no restriction on the type and shape of the battery 31, in other words, there is no restriction on the shape of the battery 31 abutting between the pen cap 2 and the mounting bracket 33.

[0074] In some embodiments, a first buckle 27 is provided on the surface of the pen cap 2 facing the pen body 1 , and a first slot 12 is provided on the inner wall of the pen body 1 at the opening 11 , and the first buckle 27 is snapped into the first slot 12 .

Taking two first buckles 27 as an example, the two first buckles 27 are located on the two side walls of the end of the pen cap 2 close to the opening 11 in the second direction, and the two first buckles 27 are respectively engaged with one first slot 12. In this way, the pen cap 2 and the pen body 1 are engaged by the first buckle 27 and the first slot 12, so that the pen cap 2 and the pen body 1 are engaged, and then when the pen body 1 and the pen body 1 are disassembled, it is only necessary to separate the first buckle 27 from the first slot 12, so as to facilitate the disassembly of the pen body 1 and the pen cap 2. Among them, the above-mentioned second direction is a direction intersecting with the first direction.

[0076] In some embodiments, a through groove structure 28 is formed around the first buckle 27 , and a guide groove 13 is formed at one end of the pen body 1 where the opening 11 is provided, and the guide groove 13 extends along the first direction to the outside of the opening 11 .

[0077] In this embodiment, the through groove structure 28 can be arranged at the end of the first buckle 27 facing the battery 31 in the first direction and on the two sides of the first buckle 27 in the third direction, and the third direction is a direction intersecting with both the first direction and the second direction. Exemplarily, the through groove structure 28 can be a U-shaped through groove structure 28, and the first bayonet is surrounded by the U-shaped through groove structure 28. In this way, since the through groove structure 28 is provided on the peripheral side of the first buckle 27, a deformation space of the first buckle 27 can be formed by the through groove structure 28, which is conducive to the separation of the first buckle 27 and the first slot 12.

[0078] In some embodiments, at least one of the positive electrode connector 321 and the negative electrode connector 322 is an elastic connector.

[0079] In this embodiment, since at least one of the positive connector 321 and the negative connector 322 is an elastic connector, the positive connector 321 and the negative connector 322 can also be elastic, which can not only enable the positive connector 321 and the negative connector 322 to provide a certain elastic force when the pressing cap 24 switches between the first state and the second state, but also provide a certain installation margin through the positive connector 321 and the negative connector 322 when the battery 31 is installed between the mounting bracket 33 and the pen cap 2, so as to facilitate the assembly of the battery 31. It should be noted that the elastic connector can be a spring, a spring sheet or other elastic components, which is not limited in the embodiment of the present application.

When both the positive electrode connector 321 and the negative electrode connector 322 are springs, the positive electrode of the battery 31 and the negative electrode of the battery 31 are both located at the end of the battery 31 facing the main board 32. Similarly, the stability of the electrical connection between the battery 31 and the main board 32 can be ensured.

[0082] In some embodiments, when the positive electrode connector 321 is a spring and the negative electrode connector 322 is an elastic sheet, the negative electrode of the battery 31 is located on the side wall of the battery 31, the positive electrode of the battery 31 is located on the end surface of the first end of the battery, and the positive electrode of the battery 31 is electrically connected to the main board 32 through the spring.

[0083] In this embodiment, since the spring sheet includes a connected connecting sheet 3221 and a connecting arm 3222, the connecting sheet 3221 is connected to the main board 32, and the connecting arm 3222 is attached to the side wall of the end of the mounting bracket 33 facing the battery 31, the connecting sheet 3221 can ensure the electrical connection strength between the spring sheet and the main board 32, and the wiring can be separated by the connecting arm 3222 and the positive electrode connector 321 to avoid short circuit. Since a connecting groove 335 is provided on the side wall of the end of the mounting bracket 33 facing the battery 31, an elastic pressing piece 32221 is provided on the connecting arm 3222, and the elastic pressing piece 32221 is pressed against the negative pole of the battery 31 through the connecting groove 335, the connecting arm 3222 can adapt to the installation position of the negative pole on the side wall of the battery 31, and the elastic pressing piece 32221 provided on the connecting arm 3222 can ensure the tightness of the connection between the negative pole connector 322 and the negative pole of the battery 31, and ensure that the elastic pressing piece 32221 is always pressed against the negative pole of the battery 31.

[0084] In some embodiments, a first guide groove 333 and a second guide groove 334 are provided at the end of the mounting bracket 33 facing the opening 11, the positive electrode connector 321 passes through the first guide groove 333 and abuts against the positive electrode of the battery 31, and the negative electrode connector 322 passes through the second guide groove 334 and abuts against the negative electrode of the battery 31.

[0085] In this embodiment, the first guide groove 333 and the second guide groove 334 may be a through groove structure 28 extending along the first direction at the end of the mounting bracket 33 facing the opening 11, and the first guide groove 333 and the second guide groove 334 may be a groove structure extending along the first direction on the side wall of the end of the mounting bracket 33 facing the opening 11, which is not limited in the embodiment of the present application. In this way, since the positive electrode connector 321 passes through the first guide groove 333 and abuts against the positive electrode connecting piece, and the negative electrode connector 322 passes through the second guide groove 334 and abuts against the negative electrode connecting piece, the positive electrode connecting piece can be guided to abut against the positive electrode of the battery 31 through the first guide groove 333, and the negative electrode connector 322 can be guided to abut against the negative electrode of the battery 31 through the second guide groove 334.

[0086] It can be seen from the above embodiments that in the embodiments of the present application, since the first end of the battery 31 is detachably connected to the mounting bracket 33, the second end of the battery 31 and the pen cap 2 are detachably connected, the main board 32 is mounted on the mounting bracket 33, and the main board 32 is connected with a positive connector 321 and a negative connector 322. The positive connector 321 abuts against the positive pole of the battery 31, and the negative connector 322 abuts against the negative pole of the battery 31.

When assembling the battery 31 into the electronic pen, the second end of the battery 31 can be connected to the pen cap 2 first, and then the second end of the battery 31 can be connected to the mounting bracket 33, and at the same time, the positive electrode connector 321 can be abutted against the positive electrode of the battery 31, and the negative electrode connector 322 can be abutted against the negative electrode of the battery 31, and then the pen cap 2 can be connected to the opening 11. In summary, in the electronic pen provided in the embodiment of the present invention, the battery 31 can be easily disassembled and assembled, which is conducive to improving the endurance of the electronic pen and the service life of the electronic pen.
