The other end of the pen tip assembly is disposed opposite to the sensor, and the pen tip assembly is movable relative to the mounting bracket.

[0007] A first seal is located near the first opening and is disposed between the housing and the mounting bracket;

[0008] And a second seal, located between the sensor and the mounting bracket, to divide the mounting bracket into a first space and a second space that are not directly connected to each other, the pen tip assembly being located in the first space, and the second space being used to accommodate an electronically controlled component electrically connected to the sensor.

[0009] Optionally, the electronic pen further includes a first waterproof structure located in the first space, the first waterproof structure being disposed between the outer wall of the pen tip assembly and the inner wall of the mounting bracket, and the first waterproof structure being located between the first seal and the sensor.

[0013] Optionally, the groove structure includes a plurality of annular grooves, and the plurality of annular grooves are arranged along the axial direction of the housing.

[0014] Optionally, the second seal includes a sealing seat, the sealing seat having a first through hole;

[0015] The sensor is at least partially embedded in the first through hole, and the sealing seat is located between the sensor and the mounting bracket to seal the gap between the sensor and the mounting bracket.

[0016] Optionally, the second seal includes a sealing block and a contact block, the sealing block having a second through hole, the contact block being at least partially embedded in the second through hole, the sensor being located in the cavity formed by the sealing block and the contact block, and the sensor contacting the pen tip assembly through the contact block.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0041] like Figures 1 to 12 As shown, this embodiment of the present invention provides an electronic pen, which includes:

[0042] The housing 1 has a first opening 100 at one end.

[0043] The writing module 2 includes a pen tip assembly 21, a mounting bracket 22, and a sensor 23. The mounting bracket 22 is installed inside the housing 1, and the pen tip assembly 21 is installed inside the mounting bracket 22. The pen tip assembly 21 is mounted on the mounting bracket 22, and one end of the pen tip assembly 21 protrudes from the housing 1 through a first opening 100. The other end of the pen tip assembly 21 is positioned opposite to the sensor 23, and the pen tip assembly 21 is movable relative to the mounting bracket 22.

[0044] The first seal 3 is located near the first opening 100 and is disposed between the housing 1 and the mounting bracket 22.

[0045] And a second seal 6, which is located between the sensor 23 and the mounting bracket 22 to divide the mounting bracket 22 into a first space 221 and a second space 222 that are not directly connected to each other. The pen tip assembly 21 is located in the first space 221, and the second space 222 is used to accommodate the electronic control assembly 5 that is electrically connected to the sensor 23.

[0046] As can be seen from the above embodiments, in this application embodiment, since the first sealing member 3 is disposed between the housing 1 and the mounting bracket 22, the gap between the housing 1 and the mounting bracket 22 can be filled by the first sealing member 3, thereby preventing external moisture from entering the housing 1 from the opening 100 away from the sensor 23 and flowing into the second space 222 of the mounting bracket 22. Furthermore, since the second sealing member 6 is located between the sensor 23 and the mounting bracket 22, dividing the mounting bracket 22 into a first space 221 and a second space 222 that cannot be directly connected, the pen tip assembly 21 is located in the first space 221, and the second space 222 is used to accommodate the electronic control component 5 electrically connected to the sensor 23. Therefore, the second sealing member 6 can isolate the first space 221 and the second space 222, preventing external moisture from entering the second space 222 from the first space 221 and avoiding corrosion and damage to the electronic control component 5 in the second space 222. In summary, in the electronic pen provided in this application embodiment, the first sealing member 3 and the second sealing member 6 achieve waterproof sealing of the electronic pen, which can effectively prevent external moisture from corroding the electronic control components 5 of the electronic pen, thereby improving the overall waterproof performance and service life of the electronic pen.

[0047] In this embodiment, the housing 1 can be a cylindrical housing structure, a square housing structure, or a housing structure of other shapes; this embodiment does not limit the shape. The housing 1 has a first opening 100 at its end in the first direction, which can also be understood as the head of the housing 1 having an opening. It should be noted that in this embodiment, the first direction can be understood as the axial direction of the housing 1, that is, the direction in which the axis extends. Specifically, the first direction can be as follows: Figure 2 and Figure 7 The direction indicated by X in the diagram.

[0048] The writing module 2, housed inside the housing 1, may include a pen tip assembly 21, a mounting bracket 22, and a sensor 23. The pen tip assembly 21 is a columnar structure. The mounting bracket 22 may be a frame structure, a cylindrical structure, or other structures. The mounting bracket 22 can be installed on the inner wall of the housing 1 by snap-fit, adhesive, sleeve, or glue. The mounting bracket 22 is mainly used to install the pen tip assembly 21, the electronic control assembly 5, and other components. For example, the mounting bracket 22 may include a module bracket 223 and a main bracket 224. The module bracket 223 is mainly used to assemble the pen tip assembly 21, enabling its installation in the housing 1. The main bracket 224 can be used to assemble the electronic control assembly 5, the button assembly 7, and other structures. For the assembly between the pen tip assembly 21 and the module support 223, in some embodiments, an assembly hole can be formed in the module support 223. The pen tip assembly 21 may include a tip and a connecting rod. A portion of the tip may extend out of the opening of the assembly hole. The portion of the tip extending out of the opening of the assembly hole may be a conical structure. The tip and one end of the connecting rod are connected. The connecting rod extends along a first direction X, and the other end of the connecting rod is in direct or indirect contact with the sensor 23. In this way, the motion trajectory information of the pen tip assembly 21 can be transmitted through the sensor 23.

[0049] It should be noted that, in the embodiments of this application, the first sealing element 3 and the second sealing element 6 can be any of the materials such as rubber, polyurethane, and polytetrafluoroethylene. The first sealing element 3 can be a ring structure, a tubular structure, or other forms of sealing structure, and the embodiments of this application do not limit this. Taking the first sealing element 3 as a ring-shaped sealing element as an example, during installation, an insert groove can be provided on the end of the mounting bracket 22 facing the orifice of the first opening 100, and a shoulder structure can be provided on the inner wall of the housing 1 at the orifice of the first opening 100. The first sealing element 3 is inserted into the insert groove and abuts against the surface formed by the shoulder structure, so that the first sealing element 3 is installed between the housing 1 and the mounting bracket 22. In addition, the second sealing element 6 can be any structure with a cavity, such as a housing structure, a ring structure, or a boss structure, so that the second sealing element 6 can be located between the sensor 23 and the mounting bracket 22, thereby dividing the mounting bracket 22 into a first space 221 and a second space 222 that cannot be directly connected to each other. The electronic control components 5 installed in the second space 222 include, but are not limited to, structures such as the motherboard 52 and the flexible circuit board 51. The sensor 23 can be electrically connected to the motherboard 52 through the flexible circuit board 51. In addition, it should be noted that the first space 221 can be a space for installing the pen tip assembly 21 in the mounting bracket 22, and the second space 222 can be a space for installing the sensor 23 and the electronic control components 5 in the mounting bracket 22.

[0050] In some embodiments, the electronic pen further includes a first waterproof structure 4 located in the first space 221, the first waterproof structure 4 being disposed between the outer wall of the pen tip assembly 21 and the inner wall of the mounting bracket 22, and the first waterproof structure 4 being located between the first seal 3 and the sensor 23.

[0051] It should be noted that if external moisture is to enter the electronic pen, it will generally enter through the first opening 100 of the housing 1, that is, through the gap between the inner wall of the housing 1 and the outer wall of the mounting bracket 22. Based on this, this embodiment uses a first seal 3 to fill the gap between the housing 1 and the mounting bracket 22, thereby preventing external moisture from entering the housing 1 through the opening 100 away from the sensor 23 and flowing into the second space 222 of the mounting bracket 22. A second seal 6 separates the first space 221 and the second space 222, preventing external moisture from entering the second space 222 from the first space 221. Since the pen tip assembly 21 needs to move relative to the mounting bracket 22, the pen tip assembly 21 needs to be in clearance fit with the mounting bracket 22. For example, the mounting bracket 22 may be provided with mounting holes, through which the pen tip assembly 21 passes and fits with the mounting bracket 22 with a gap. The end of the pen tip assembly 21 furthest from the first opening 100 is positioned relative to the sensor 23. Therefore, the gap between the pen tip assembly 21 and the mounting bracket 22 also needs to be waterproofed to meet the waterproof requirements of the electronic pen. Based on this, this embodiment provides a first waterproof structure 4 between the outer wall of the pen tip assembly 21 and the inner wall of the mounting bracket 22. This prevents moisture from entering the electronic control component 5 through the gap between the outer wall of the pen tip assembly 21 and the inner wall of the mounting bracket 22, effectively preventing external moisture from corroding the electronic pen's electronic control component 5 and improving the overall waterproof performance and lifespan of the electronic pen.

[0052] It should also be noted that the first waterproof structure 4 can be a seal installed between the inner wall of the mounting bracket 22 and the outer wall of the pen tip assembly 21. The first waterproof structure 4 can also be a groove structure 42 set between the inner wall of the mounting bracket 22 and the outer wall of the pen tip assembly 21, or other structures that can prevent water vapor from entering the electronic control component 5. This application embodiment does not limit this.

[0053] For the first waterproof structure type 4, such as Figure 4 As shown, in one possible implementation, the first waterproof structure 4 is a sealing ring 41, which is fitted onto the pen tip assembly 21 and located between the inner wall of the mounting bracket 22 and the outer wall of the pen tip assembly 21.

[0054] In this embodiment, since the first waterproof structure 4 is a sealing ring 41, which is fitted onto the pen tip assembly 21 and located between the inner wall of the mounting bracket 22 and the outer wall of the pen tip assembly 21, the sealing ring 41 can be positioned between the inner wall of the mounting bracket 22 and the outer wall of the pen tip assembly 21, blocking the flow of moisture between the outer wall of the pen tip assembly 21 and the inner wall of the mounting bracket 22. This effectively prevents external moisture from corroding the electronic pen's electronic control components 5. It should be noted that during the installation of the above embodiment, an interference fit can be made between the sealing ring 41 and the pen tip assembly 21, and the outer wall of the sealing ring 41 can be interference-fitted with the inner wall of the mounting bracket 22, so that the sealing ring 41 can completely block the flow channel between the outer wall of the pen tip assembly 21 and the inner wall of the mounting bracket 22.

[0055] For the first waterproof structure type 4, in another possible implementation, such as Figure 10 As shown, the first waterproof structure 4 is a groove structure 42 formed on the outer wall of the pen tip assembly 21.

[0056] In this embodiment, since the first waterproof structure 4 is a groove structure 42 formed on the outer wall of the pen tip assembly 21, gas can be filled in the groove structure 42 so that the air pressure at the groove structure 42 is greater than the air pressure outside the electronic pen. Thus, under the action of the air pressure difference, water vapor is prevented from entering the electronic control component 5 through the gap between the outer wall of the pen tip assembly 21 and the inner wall of the mounting bracket 22.

[0057] In some embodiments, the groove structure 42 includes a plurality of annular grooves, and the plurality of annular grooves are arranged along the axial direction of the housing 1.

[0058] In this embodiment, since the groove structure 42 includes multiple annular grooves and the multiple annular grooves are arranged along the axial direction of the shell 1, the multiple annular groove structures 42 can form multiple high-pressure areas, further increasing the air pressure at the groove structure 42 and further enhancing the barrier effect of the groove structure 42 on the entry of water vapor.

[0059] In some embodiments, the second seal 6 includes a sealing seat 61. The sealing seat 61 has a first through hole in the middle that extends along the axial direction of the housing 1. The sensor 23 is at least partially embedded in the first through hole. The sealing seat 61 is located between the sensor 23 and the mounting bracket 22 and is used to seal the gap between the sensor 23 and the mounting bracket 22.

[0060] In this embodiment, the sealing seat 61 can be a plate-like structure or a block-like structure. A first through hole extending axially along the housing 1 can be formed in the middle of the sealing seat 61, allowing a portion of the sensor 23 to be located in the first through hole, thereby enabling the sealing seat 61 to cover the sensor 23. Thus, since the sealing seat 61 has a first through hole extending axially along the housing 1 in its middle, and the sensor 23 is at least partially embedded in the first through hole, with the sealing seat 61 located between the sensor 23 and the mounting bracket 22, the sealing seat 61 can at least surround the periphery of the sensor 23, sealing the gap between the sensor 23 and the mounting bracket 22 and preventing external moisture from entering the second space 222.

[0061] It should be noted that in the above embodiment, the sealing seat 61 may include a base 611 and a boss 612. The boss 612 is disposed on the end face of the base 611 facing the first opening 100. During installation, the inner sidewall of the mounting bracket 22 abuts against the boss 612, and the end of the mounting bracket 22 away from the first opening 100 abuts against the base 611, thereby forming a better sealing effect and further enhancing the sealing performance of the sealing seat 61. It should also be noted that in this embodiment, the mounting bracket 22 can be divided into a first space 221 and a second space 222 that cannot be directly connected to each other by the sealing seat 61 and the sensor 23, that is, the sealing seat 61 and the sensor 23 are located at the junction of the first space 221 and the second space 222.

[0062] Regarding the structure of the second seal 6, in other embodiments, such as Figure 4 As shown, the second seal 6 includes a sealing block 62 and a contact block 63. The sealing block 62 has a second through hole, and the contact block 63 is at least partially embedded in the second through hole. The sensor 23 is located in the cavity formed by the sealing block 62 and the contact block 63, and the sensor 23 contacts the pen tip assembly 21 through the contact block 63.

[0063] In this embodiment, the second sealing member 6 is a split structure. The sealing block 62 included in the second sealing member 6 can be a box structure, that is, the sealing block 62 can be a box structure with a single-end opening. The opening of the sealing block 62 can be located at the end of the sealing block 62 away from the first opening 100, and the opening at the end of the sealing block 62 can provide a channel for electrical connection between the sensor 23 and the electronic control component 5. The contact block 63 can be any of the columnar structures such as cylindrical structure and prismatic structure. The contact block 63 can be fixed to the end of the sealing block 62 near the first opening 100 by snap-fit, plug-in or other means. For example, an embedding hole can be opened on the end of the sealing block 62 near the first opening 100, so that part of the contact block 63 passes through the embedding hole and is installed in the inner cavity of the sealing block 62 to contact the sensor 23, and the other part of the contact block 63 is located outside the sealing block 62 and contacts the end of the pen tip assembly 21 away from the first opening 100. Thus, since the sealing block 62 has a second through hole, the contact block 63 is at least partially embedded in the second through hole. The sensor 23 is located in the cavity formed by the sealing block 62 and the contact block 63. The sensor 23 contacts the pen tip assembly 21 through the contact block 63. Therefore, the pen tip assembly 21 and the sensor 23 can be indirectly contacted through the contact block 63, and the sensor 23 can be located in the cavity formed by the sealing block 62 and the contact block 63. In addition, in some embodiments, the outer side of the sealing block 62 may include a flange structure 621 pointing towards the housing 1. The flange structure 621 is embedded between the end of the electronic control assembly 5 and the module bracket 223 for mounting the pen tip assembly 21, thereby ensuring that the sealing block 62 achieves a better sealing effect. It should be noted that the material of the contact block 63 provided in this application embodiment can be a flexible material or a rigid material. The material of the contact block 63 is determined according to the type of sensor 23, and this application embodiment does not limit it.

[0064] It should be noted that, in this embodiment, the mounting bracket 22 is divided into a first space 221 and a second space 222, which are not directly connected to each other, by the sealing block 62 and the contact block 63. The sensor 23 is located in the second space 222. Specifically, the mounting bracket 22 may include a mounting plate 225, and the flexible circuit board 51 may be mounted on the mounting plate 225. The second space 22 may form multiple subspaces for mounting multiple components included in the electronic control assembly 5. In some exemplary embodiments, the space between the mounting plate 225 and the sealing block 62 may form the first subspace included in the second space 222, which is used to mount the sensor 23. The space between the ends of the mounting plate 225 and the mounting bracket 22 away from the first opening 100 forms the second subspace included in the second space 222, which is used to mount the main board 52. The flexible circuit board 51 extends from the first subspace to the second subspace and is electrically connected to the main board 52.

[0065] In some embodiments, such as Figure 5 As shown, the electronic pen also includes a button assembly 7, which includes a button body 71, a button bracket 72, and a third seal 73. The button bracket 72 is installed between the inner wall of the housing 1 and the electronic control component 5. The housing 1 has a third through hole, in which the button body 71 is embedded. The third seal 73 is installed between the button body 71 and the electronic control component 5, and at least partially embedded in the button bracket 72.

[0066] In this embodiment, the electronic control component 5 can be mounted inside the housing 1 via the mounting bracket 22. The button body 71 can be a plate-like structure, a column-like structure, or other structures with a pressing surface. The button bracket 72 is a frame-shaped structure, and the button bracket 72 has at least a connecting part that can be connected to the electronic control component 5 and a mounting part for embedding the third sealing member 73. For example, the button bracket 72 can be a frame-shaped structure with a fourth through hole in the middle. The bottom of the button bracket 72 is provided with a snap-fit ​​structure, and the electronic control component 5 is provided with a slot, so that the snap-fit ​​structure snaps into the slot to realize the connection between the button bracket 72 and the electronic control component 5. The third sealing member 73 can be embedded in the fourth through hole. The bottom of the third sealing member 73 contacts the contact point on the electronic control component 5, and the top of the third sealing member 73 contacts the button body 71. It can be understood that at least part of the structure of the third sealing member 73 needs to contact both the button body 71 and the electronic control component 5 simultaneously. Thus, since the third seal 73 is installed between the button body 71 and the electronic control component 5, and the third seal 73 is at least partially embedded in the button bracket 72, the third seal 73 can seal the gap between the button body 71 and the button bracket 72. Furthermore, since the button bracket 72 is installed between the inner wall of the housing 1 and the electronic control component 5, the third seal 73 is simultaneously located in the gap between the button bracket 72 and the housing 1. This allows the third seal 73 to completely seal the gap at the button assembly 7, preventing external moisture from entering the pen through the gap at the button assembly 7, further improving the pen's waterproof performance. In the above embodiment, the electronic control component 5 that cooperates with the button assembly 7 may include a motherboard 52.

[0067] In some embodiments, such as Figure 12 As shown, the electronic pen also includes a pen cap 8 and a fourth seal 9. The pen cap 8 is mounted on the end of the housing 1 that is axially away from the first opening 100, and the fourth seal 9 is installed between the pen cap 8 and the housing 1.

[0068] In this embodiment, the pen cap 8 may include a pressing part and a connecting rod. The pressing part may be a pressing plate, which is fixed to the end of the pressing rod. The pressing rod is inserted into the port at the other end of the housing 1 in the first direction, and the pressing part and the end of the housing 1 axially away from the first opening 100 abut against each other. In this embodiment, external moisture can enter the interior of the electronic pen through the gap between the pen cap 8 and the housing 1. Based on this, in this embodiment, a fourth sealing member 9 is installed between the pen cap 8 and the housing 1, that is, the fourth sealing member 9 is embedded between the outer wall of the connecting rod and the inner wall of the housing 1, thereby preventing external moisture from entering the channel of the electronic pen through the gap between the pen cap 8 and the housing 1, further improving the waterproof performance of the electronic pen.

[0069] In some embodiments, such as Figure 6 As shown, the electronic pen also includes a pressing assembly 10 and a fifth seal 11. The pressing assembly 10 includes a pressing cap 101 and a pressing bracket 102. The pressing bracket 102 is installed on the end of the housing 1 away from the first opening 100 in the axial direction. The pressing cap 101 is movably connected inside the pressing bracket 102. The fifth seal 11 is installed between the pressing bracket 102 and the housing 1.

[0070] In this embodiment, unlike the structure of the pen cap 8 described above, the pen cap 8 in this embodiment includes a pressing cap 101 and a pressing bracket 102. If it is necessary for the pressing cap 101 to spring back, the pressing assembly 10 may also include an elastic return member. For example, the pressing cap 101 may include a pressing sheet and a pressing rod, with the pressing sheet fixed to the end of the pressing rod. The elastic return member may be an integral elastic structure or a composite elastic structure composed of multiple elastic components; this embodiment does not limit this. The pressing bracket 102 is a cylindrical structure with openings at both ends. During installation, the elastic return member can extend from one end of the pressing bracket 102 into the movable cavity of the pressing bracket 102, and the end of the elastic return member can be connected to the pressing cap 101, while the pressing cap 101 can at least partially extend into the movable cavity of the pressing bracket 102. Based on the above structure, external moisture can enter the interior of the electronic pen through the gap between the pressing bracket 102 and the housing 1. Based on this, a fifth sealing element 11 is installed between the pressing bracket 102 and the housing 1. That is, the fifth sealing element 11 prevents external moisture from entering the second space 222 of the electronic pen through the gap between the pressing bracket 102 and the housing 1, further improving the waterproof performance of the electronic pen. It should be noted that the fifth sealing element 11 can be a cylindrical structure, and a groove can be opened on the outer wall of the pressing bracket 102 so that the fifth sealing element 11 is embedded in the groove. The larger outer wall area of ​​the fifth sealing element 11 provides a larger sealing area, thereby further improving the sealing effect of the fifth sealing element.

[0071] As can be seen from the above embodiments, in this application embodiment, since the first sealing member 3 is disposed between the housing 1 and the mounting bracket 22, the gap between the housing 1 and the mounting bracket 22 can be filled by the first sealing member 3, preventing external moisture from entering the housing 1 through the first opening 100 and then flowing into the second space 222 of the mounting bracket 22. Furthermore, since the second sealing member 6 is located between the sensor 23 and the mounting bracket 22, dividing the mounting bracket 22 into a first space 221 and a second space 222 that cannot be directly connected, and the pen tip assembly 21 is located in the first space 221, while the second space 222 is used to accommodate the electronic control component 5 electrically connected to the sensor 23, the second sealing member 6 can isolate the first space 221 and the second space 222, preventing external moisture from entering the second space 222 from the first space 221 and causing corrosion and damage to the electronic control component 5. In summary, in the electronic pen provided in this application embodiment, the first sealing member 3 and the second sealing member 6 achieve waterproof sealing of the electronic pen, effectively preventing external moisture from corroding the electronic control component 5, and improving the overall waterproof performance and service life of the electronic pen.
