[0037] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0038] See also Figure 1-Figure 3 As shown, an embodiment of the utility model provides a stylus pen having a first direction X, wherein the stylus pen comprises a pen body 1, a pen cap assembly 2, a pen tip assembly 3, a pen core assembly 4 and a first sealing member 5, wherein the pen body 1 has a first end 11 and a second end 12, wherein the first end 11 and the second end 12 are arranged opposite to each other along the first direction X, and the interior of the pen body 1 is hollow; the pen cap assembly 2 is installed in the pen body 1 and extends out of the first end 11 along the first direction X; the pen tip assembly 3 is installed in the pen body 1 and extends out of the second end 12 along the first direction X; the pen core assembly 4 is installed in the pen body 1, and the pen core assembly 4 and the pen cap assembly 2 are arranged in sequence along the first direction X, and the pen core assembly 4 has a concave cavity 401 at one end facing the pen cap assembly 2, and the pen cap assembly 2 abuts against the concave cavity 401 and forms a first accommodating space with the pen core assembly 4 and the pen body 1; the first sealing member 5 is embedded in the first accommodating space, and the first sealing member 5 is respectively fitted with the pen core assembly 4, the pen cap assembly 2 and the pen body 1.
[0039] A first sealing member 5 is embedded in a first accommodating space formed by the pen cap assembly 2, the pen core assembly 4 and the pen body 1. The first sealing member 5 blocks the infiltration channel from the gap between the first end 11 of the pen body 1 and the pen cap assembly 2 along the inner wall of the pen body 1 into the pen core assembly 4, thereby preventing external liquids or dust and other substances from infiltrating into the interior of the pen core assembly 4 from the gap between the pen cap assembly 2 and the pen body 1, thereby preventing the infiltrated liquid or dust from affecting the service life of the internal components of the pen core assembly 4, and improving the waterproof and dustproof performance of the stylus pen.
[0040] During assembly, the pen tip assembly 3 and the pen core assembly 4 can be installed first, and the installation position of the first sealing member 5 can be determined. After installing the first sealing member 5, the pen body 1 and the pen cap assembly 2 can be installed. By squeezing the pen body 1, the pen core assembly 4, and the pen cap assembly 2, the gap between the pen cap assembly 2 and the pen body 1 can be sealed.
[0041] See also Figure 3 In some embodiments, the end of the cap assembly 2 facing the core assembly 4 is provided with an inserting portion 211, a connecting portion 212 and a convex ring 213 in sequence along the first direction X, the inserting portion 211 abuts against the concave cavity 401, the outer edge of the convex ring 213 fits with the pen body 1, the connecting portion 212 is inclined, and the connecting portion 212 is connected between the inserting portion 211 and the convex ring 213; the first sealing member 5 has an inclined surface 51 for fitting to the surface of the connecting portion 212. The connecting portion 212 plays a connecting transition role between the inserting portion 211 and the convex ring 213, and the space between the convex ring 213, the connecting portion 212, the core assembly 4, and the pen body 1 forms a first accommodating space. The first sealing member 5 in the first accommodating space fits with the connecting portion 212 through the inclined surface 51, which facilitates the assembly of the first sealing member 5 and the connecting portion 212. During the assembly process, the first sealing member 5 will shrink inward due to the pressure of the pen body 1. Due to the inclined surface 51, the operation is more convenient when the subsequent pen cap assembly 2 is installed, and the contact area between the first sealing member 5 and the pen cap assembly 2 is also larger, so that a better waterproof effect is achieved. If the inclined surface 51 is not provided, the remaining assembly space of the first sealing member 5 becomes smaller after being compressed, and a greater force needs to be applied when installing subsequent parts, and the waterproof effect is not as good as the former.
[0042] See also Figure 3 In some embodiments, the outer wall of the concave cavity 401 of the refill assembly 4 is provided with a protrusion 402 facing the first accommodating space, and the first sealing member 5 is provided with a groove for being clamped on the protrusion 402. The cooperation between the groove and the protrusion 402 ensures the stability of the first sealing member 5 in the first accommodating space.
[0043] In some embodiments, the pen cap assembly 2 includes a pen cap 21 and a main bracket 22, the main bracket 22 is coaxially arranged in the pen body 1, the pen cap 21 is installed on the main bracket 22, and the end of the pen cap 21 is inserted into the concave cavity 401 of the main bracket 22 inserted into the pen core assembly 4. The insertion portion 211, the connecting portion 212 and the convex ring 213 are all arranged at one end of the pen cap 21. When the pen cap 21 is pressed, the pen cap 21 can move in the main bracket 22, and the pen cap 21 presses the pen core assembly 4 and the pen tip assembly 3 to move, so that the pen tip 31 of the pen tip assembly 3 extends out of the second end 12 for use. In order to realize the automatic resetting of the pen cap 21 and the pen tip 31, springs are provided in the pen cap assembly 2 and the pen tip assembly 3.
[0044] See also Figure 2 and Figure 4 As shown, in some embodiments, one end of the core assembly 4 facing away from the cap assembly 2 abuts against the second end 12 of the pen body 1, and a second accommodation space is formed between the core assembly 4 and the pen body 1; the stylus further comprises a second sealing member 6, which is embedded in the second accommodation space and fits the core assembly 4 and the pen body 1 respectively. The second sealing member 6 blocks the infiltration channel from the gap between the second end 12 of the pen body 1 and the nib assembly 3 to the inside of the core assembly 4 along the gap between the pen body 1 and the core assembly 4, thereby preventing external liquids or dust and other substances from infiltrating into the core assembly 4 from the gap between the nib assembly 3 and the second end 12 of the pen body 1, further improving the waterproof and dustproof performance of the stylus.
[0045] See also Figure 4 As shown, in some embodiments, the refill assembly 4 includes an electrode holder 41 and an electrode 42. The electrode holder 41 is disposed in the pen body 1 and is spaced apart from the second end 12. The electrode 42 is mounted on the electrode holder 41. The space between the electrode holder 41, the electrode 42, and the pen body 1 forms a second accommodation space. The second accommodation space is formed by the electrode holder 41, the electrode 42, and the pen body 1. The second seal 6 in the second accommodation space can prevent external liquids or dust and other substances from penetrating from the gap between the electrode holder 41 and the pen body 1 and damaging the electrode 42. The side surfaces of the second seal 6 are respectively fitted with the pen body 1, the electrode holder 41, and the electrode 42 to ensure the sealing of the gap between the electrode holder 41 and the pen body 1 by the second seal 6. During assembly, the electrode holder 41 is installed first, and the electrode 42 is installed after the position of the second seal 6 is determined, so that the electrode 42 is pressed against the side surfaces of the second seal 6. Then, the pen body 1 is installed so that the pen body 1 is pressed against the front end of the second sealing member 6 to achieve interference fit between the electrode 42, the electrode bracket 41, the second sealing member 6 and the pen body 1, thereby achieving waterproof and dustproof effects.
[0046] See also Figure 4As shown, in some embodiments, the refill assembly 4 further includes a pressure sensing element 43 and a connecting assembly 44, the pressure sensing element 43 and the electrode bracket 41 are arranged at intervals along the first direction X, the connecting assembly 44 connects the pressure sensing element 43 and the pen tip assembly 3, and the pressure on the pen tip assembly 3 is sensed by the pressure sensing element 43; the stylus further includes a third seal 7, one end of the third seal 7 is connected to the connecting assembly 44, and the other end of the third seal 7 is embedded in the gap between the pressure sensing element 43 and the electrode bracket 41. The third seal 7 blocks the infiltration channel from the gap between the pen tip assembly 3 and the pen body 1 along the pen tip assembly 3 to the inside of the stylus, thereby preventing external liquid or dust from infiltrating and damaging the pressure sensing element 43. The pressure sensing element 43 is a pressure sensor. During assembly, the pen tip assembly 3 is assembled first, and then the third seal 7 and the connecting assembly 44 are assembled, and then the pressure sensing element 43 and the electrode bracket 41 are used to cover the third seal 7 to ensure the sealing of the third seal 7 and prevent liquid from infiltrating into the pressure sensing element 43.
[0047] In some embodiments, the pen tip assembly 3 includes a pen tip 31 and a pen tip connecting rod 32, the pen tip 31 is connected to one end of the pen tip connecting rod 32, and the pen tip 31 can extend to the second end 12 of the pen body 1. The pen tip connecting rod 32 is a metal rod, and the electrode bracket 41 is a metal bracket. Therefore, the gap between the pen tip connecting rod 32 and the electrode bracket 41 does not need to be sealed by a seal, and the third seal 7 is connected between the pressure sensing element 43 and the electrode bracket 41.
[0048] In some embodiments, the connection assembly 44 includes a first connection block 441 and a second connection block 442, wherein the first connection block 441 is connected to the pen tip assembly 3, and the second connection block 442 is connected between the first connection block 441 and the pressure sensing element 43. The third sealing member 7 is connected to the first connection block 441 to reduce the space between the third sealing member 7 and the pen tip assembly 3 to prevent external liquid from being stored in this space.
[0049] See also Figure 4 As shown, in some embodiments, the third seal 7 is partially embedded in the connecting component 44 to ensure the connection stability between the third seal 7 and the connecting component 44, and when the stylus pen is writing, when the pen tip component 3 presses the connecting component 44 inward, the third seal 7 can move synchronously with the connecting component 44. The third seal 7 can be partially embedded in the first connecting block 441. In some embodiments, the third seal 7 and the connecting component 44 are integrally formed, and can be integrally formed by injection molding.
[0050] See also Figure 4As shown, in some embodiments, the third seal 7 has a bending portion 71, and the third seal 7 is bent along the first direction X toward the pen tip assembly 3 to form the bending portion 71. The bending portion 71 provides a buffer for the deformation of the third seal 7, so as to avoid the third seal 7 being subjected to a large stress when the stylus is writing, thereby causing the third seal 7 to be damaged, and to avoid the third seal 7 absorbing more force from the pen tip assembly 3, resulting in a greater force required for the pressure sensing element 43 to sense the pressure change. The bending portion 71 is U-shaped, and the U-shaped opening faces the pressure sensing element 43.
[0051] In some embodiments, the first sealing member 5, the second sealing member 6 and the third sealing member 7 are all soft rubber pads, such as silicone pads. The soft rubber pads have good elasticity and corrosion resistance, strong adhesion and filling properties, and are easy to be processed into various shapes, which improves the flexibility and applicability of manufacturing, adapts to the sealing requirements of different structures, and can effectively improve the waterproof and dustproof performance. The soft rubber pad is waterproof because the way it fills the holes prevents liquid from entering, has excellent water resistance and weather resistance, and can maintain the waterproof effect for a long time.
[0052] It should be noted that in the present invention, the refill assembly 4 refers to the combination of structural parts of the stylus pen except the pen body 1, the pen tip assembly 3, and the pen cap assembly 2. Therefore, the refill assembly 4 includes not only the electrode bracket 41, the electrode 42, the pressure sensing element 43 and other components, but also the battery 45, the battery mounting shell 46 and other components, which are not described in detail in the present invention.
[0053] In summary, the embodiment of the utility model provides a stylus pen, which realizes the sealing of the internal structure of the entire stylus pen by embedding seals of different shapes between the pen cap assembly 2 and the pen core assembly 4, between the electrode bracket 41 of the pen core assembly 4 and the pen body 1, and between the pen tip assembly 3 and the pressure sensing element 43, thereby achieving the purpose of waterproofing and dustproofing.
[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
