[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0028] See also Figures 1 to 5As shown, according to an embodiment of the present application, an electromagnetic pen is provided, wherein a accommodating chamber is provided in the electromagnetic pen, wherein a replacement part 3 is provided in the accommodating chamber, and the electromagnetic pen comprises a first shell 1 and a second shell 2, and the first shell 1 and the second shell 2 can be detachably connected to open or close the accommodating chamber.

[0029] By providing a storage cavity within the electromagnetic pen, a storage location for the replacement part 3 is provided. The replacement part 3 can be placed inside the electromagnetic pen and carried along with the electromagnetic pen. The replacement part 3 can then be taken out and replaced when needed, avoiding the problem of the electromagnetic pen being unusable due to forgetting to bring the replacement part 3. By providing a first shell 1 and a second shell 2 that are detachably connected, the storage cavity can be opened to remove the replacement part 3 and closed to store the replacement part 3, thereby improving the user experience.

[0030] The first shell 1 and the second shell 2 are connected to form a shell of the electromagnetic pen, and other components of the electromagnetic pen are arranged on the shell.

[0031] The first shell 1 and the second shell 2 together form a housing cavity. After the first shell 1 and the second shell 2 are connected, the housing cavity is sealed into a sealed chamber, thereby effectively protecting the replacement part 3 and preventing external impurities from entering the housing cavity. After the first shell 1 and the second shell 2 are disassembled and separated, the housing cavity is opened, and the replacement part 3 can be removed from the housing cavity.

[0032] Among them, the replacement part 3 is a component in the electromagnetic pen that is easily damaged. For example, in this embodiment, the replacement part 3 is a pen tip, which can be carried with the electromagnetic pen. The pen tip can be taken out and replaced when needed, avoiding the problem of the electromagnetic pen being unusable due to forgetting to carry the pen tip.

[0033] The accommodating cavity is formed in the first housing 1 and / or the second housing 2. The first housing 1 can be separated from the second housing 2 to open the accommodating cavity, and the first housing 1 can be engaged with the second housing 2 to close the accommodating cavity. The structure is simple and reliable, easy to operate, and can effectively protect the replacement component 3 in the accommodating cavity.

[0034] The accommodating cavity may be formed in the first shell 1 , and the second shell 2 may be detachably covered on the opening of the accommodating cavity of the first shell 1 , thereby realizing opening and closing of the accommodating cavity.

[0035] The accommodating cavity may be formed in the second shell 2 , and the first shell 1 can be detachably covered on the opening of the accommodating cavity of the second shell 2 , thereby realizing opening and closing of the accommodating cavity.

[0036] In this embodiment, the first cavity 11 of the accommodating chamber is formed in the first housing 1, and the second cavity 21 of the accommodating chamber is formed in the second housing 2. When the first housing 1 and the second housing 2 are connected, the first end of the replacement part 3 is disposed in the first cavity 11, and the second end of the replacement part 3 is disposed in the second cavity 21. With this arrangement, when the accommodating chamber is opened, part of the replacement part 3 is located outside the first cavity 11 or the second cavity 21, making it easier for people to take the replacement part 3.

[0037] The first cavity 11 and the second cavity 21 are both components of the accommodating chamber. In this embodiment, the first cavity 11 and the second cavity 21 together constitute the accommodating chamber.

[0038] The opening of the first cavity 11 and the opening of the second cavity 21 are arranged opposite to each other, and their shapes and sizes match, thereby making the accommodating cavity transition smooth.

[0039] Specifically, taking the replacement part 3 as a pen tip as an example, the first end of the pen tip is the root end, and the second end is the tip end. When the first shell 1 and the second shell 2 are connected, the root end of the pen tip is located in the first cavity 11 of the first shell 1, and the tip end of the pen tip is located in the second cavity 21 of the second shell 2, thereby achieving good fixation of the pen tip. When the first shell 1 and the second shell 2 are separated, the root end of the pen tip is located in the first cavity 11 of the first shell 1. As the second shell 2 detaches from the first shell 1, the tip end of the pen tip also detaches from the second cavity 21, exposing the tip end of the pen tip to the outside, making it easier for the user to pick up the pen tip.

[0040] The size and shape of the accommodating cavity match the replacement part 3 stored therein, which can effectively fix the replacement part 3 and prevent the replacement part 3 from shaking in the accommodating cavity.

[0041] There are at least two accommodating cavities, which are arranged along the circumference of the electromagnetic pen, increasing the number of replacement parts 3 that can be accommodated, improving the convenience of use, and also making the overall center more centered, ensuring comfort during use.

[0042] Wherein, all the accommodating cavities are evenly arranged along the circumference of the electromagnetic pen, and all the accommodating cavities are located at the same position in the axial direction of the electromagnetic pen.

[0043] Specifically, in this embodiment, the number of the accommodating cavities is four, and the four accommodating cavities are evenly arranged along the circumference of the electromagnetic pen, and the two ends of the accommodating cavities are located at the same position in the axial direction of the electromagnetic pen.

[0044] The first shell 1 and the second shell 2 are connected along the length direction of the electromagnetic pen, and the accommodating cavity extends along the length direction of the electromagnetic pen, which is convenient for disassembly and assembly of the first shell 1 and the second shell 2, and also convenient for opening the accommodating cavity and storing the pen tip.

[0045] The length direction of the electromagnetic pen can also be understood as the axial direction of the electromagnetic pen.

[0046] The first shell 1 and the second shell 2 are both in the shape of long strips, and the first shell 1 and the second shell 2 are axially connected to form the shell of the electromagnetic pen.

[0047] The accommodating cavity is also opened along the axial direction of the electromagnetic pen, and the pen tip is installed into the accommodating cavity along the axial direction of the electromagnetic pen. That is, after the first shell 1 and the second shell 2 are connected and the pen tip is in the accommodating cavity, the pen tip is also placed along the axial direction of the electromagnetic pen, which reduces the space occupied.

[0048] The accommodating cavities extend along the axial direction of the electromagnetic pen and are evenly arranged along the circumference. In the axial direction of the electromagnetic pen, each accommodating cavity is at the same position, and the center of the electromagnetic pen is more centered, ensuring a good feel when using it.

[0049] A first connecting structure is provided on the first shell 1, and a second connecting structure is provided on the second shell 2. The first connecting structure and the second connecting structure can be detachably connected, ensuring the reliability and stability of the connection between the first shell 1 and the second shell 2, while facilitating disassembly and installation.

[0051] The first connection structure and the second connection structure may be connected by snapping, magnetic connection, etc.

[0052] The first shell 1 is provided with a plug-in column 12 , and the second shell 2 is provided with a plug-in hole 22 . The plug-in column 12 is inserted into the plug-in hole 22 . The first connection structure is provided on the plug-in column 12 , and the second connection structure is provided on the plug-in hole 22 .

[0053] By setting the plug-in column 12 and the plug-in hole 22, a setting position is provided for the first connecting structure and the second connecting structure, and a guiding function can be provided for the first shell 1 and the second shell 2 during installation, which facilitates connection. Moreover, through the cooperation of the plug-in column 12 and the plug-in hole 22, the connection between the first shell 1 and the second shell 2 is made more secure.

[0054] The plug post 12 extends along the length of the electromagnetic pen, and the plug hole 22 also extends along the length of the electromagnetic pen. That is, the first housing 1, the plug post 12, the second housing 2 and the plug hole 22 all extend along the length of the electromagnetic pen.

[0055] The shape and size of the plug-in post 12 match the shape and size of the plug-in hole 22 .

[0057] The first housing 1 is coaxially arranged with the plug-in column 12 , and the second housing 2 is coaxially arranged with the plug-in hole 22 .

[0058] Among them, the plug-in column 12 is provided with an anti-rotation rib, which extends along the axial direction of the plug-in column 12 and protrudes outward along the radial direction of the plug-in column 12. The second shell 2 is provided with an anti-rotation groove corresponding to the anti-rotation rib. The anti-rotation groove is recessed into a groove along the radial direction of the second shell 2 toward the outside of the second shell 2, and extends into a strip groove along the axial direction of the second shell 2. The notch of the anti-rotation groove is located on the hole wall of the plug-in hole 22. The formation and size of the anti-rotation groove are adapted to the anti-rotation rib. When the plug-in column 12 is inserted into the plug-in hole 22, the anti-rotation rib is synchronously inserted into the anti-rotation groove along the axial direction, thereby forming a limit in the axial direction of the plug-in column 12 and the second shell 2, preventing the plug-in column 12 from rotating in the plug-in hole 22.

[0059] As a feasible embodiment, the first connecting structure includes a buckle 121, which is provided on the outer peripheral wall of the plug-in post 12 and protrudes radially from the plug-in post 12. The second connecting structure includes a slot 221, which is provided on the wall of the plug-in hole 22 corresponding to the buckle 121. The provision of the buckle 121 and the slot 221 makes the connection between the first shell 1 and the second shell 2 more compact, less prone to loosening, and also facilitates assembly and disassembly.

[0060] There are at least two buckles 121 , which are arranged along the circumference of the plug-in column 12 . The slots 221 and the buckles 121 are arranged in a one-to-one correspondence, further ensuring good connection strength.

[0061] The two ends of the buckle 121 along the axial direction of the electromagnetic pen are arc surfaces, so that the buckle 121 can enter or move out of the slot 221 .

[0062] The buckle 121 protrudes from the outer peripheral wall of the plug-in post 12 along the radial direction of the plug-in post 12 .

[0063] The card slot 221 is recessed toward the outer side of the second housing 2 along the radial direction of the second housing 2 . The notch of the card slot 221 is located on the hole wall of the plug hole 22 .

[0064] The shape and size of the buckle 121 match those of the slot 221 .

[0065] Specifically, in this embodiment, the buckle 121 is in an elongated shape, and its length direction is in the same direction as the circumference of the plug post 12 . The slot 221 is in an elongated shape, and its length direction is in the same direction as the circumference of the second housing 2 .

[0066] The number of the card slots 221 and the number of the card buckles 121 are the same, and they are plugged in one-to-one.

[0067] Specifically, in this embodiment, there are four buckles 121 and four slots 221 . The four buckles 121 are evenly arranged along the circumference of the plug-in column 12 , and the four slots 221 are evenly arranged along the circumference of the second housing 2 .

The magnetic attraction is used to achieve the connection between the first shell 1 and the second shell 2, making assembly and disassembly operations easier.

[0069] There are at least two first magnets, and the at least two first magnets are arranged along the circumference of the plug-in column 12. The second magnets are arranged in a one-to-one correspondence with the first magnets, further ensuring good connection strength.

[0070] The first magnet and the corresponding second magnet have different surface magnetism.

[0071] The shape and size of the first magnet are adapted to the shape and size of the second magnet.

[0072] Specifically, in this embodiment, the first magnet is in the shape of an elongated strip, and its length direction is in the same direction as the circumference of the plug-in column 12.
