[0044] It can be understood that at least a part of the through hole 404 is disposed opposite to the relief opening 111, so that the through hole 404 communicates with the relief opening 111. Specifically in this embodiment, the through hole 404 is disposed directly opposite to the relief opening 111.
[0045] As Figure 4 shown, the electronic component is disposed in the storage cavity 401; or, the electronic component is disposed in the storage cavity 401 and extends out of the pen tube 100 through the through hole 404 and the relief opening 111; wherein, the electronic component is in interference fit with the seal 400.
[0046] As Figure 3 shown, specifically, the electronic component includes an interface 200; the relief opening 111 includes a first relief opening 120; the through hole 404 includes a first through hole 402; wherein, the first through hole 402 is disposed opposite to the first relief opening 120; the interface 200 is disposed in the storage cavity 401 of the seal 400 and is disposed opposite to the first relief opening 120, or, the interface 200 is disposed in the storage cavity 401 of the seal 400 and extends into the first relief opening 120.
[0047] Combined with Figure 3 , Figure 5 andFigure 6 The seal 400 has a first sealing portion 410. The outer side wall of the first sealing portion 410 is in interference fit with the wall of the inner cavity 110. The interface 200 is also in interference fit with the seal 400. In this way, the sealing of the position where the interface 200 is located can be achieved.
[0048] As Figure 4 shown, further, the electronic assembly further includes a wiping assembly 300; the relief opening 111 includes a second relief opening 130; the through hole 404 includes a second through hole 403; wherein, the second through hole 403 is disposed opposite to the second relief opening 130; the wiping assembly 300 is disposed in the storage cavity 401 of the seal 400 and extends out of the pen tube 100 through the second through hole 403 and the second relief opening 130.
[0049] Combined with Figure 4 、 Figure 5 and Figure 6 shown, the seal 400 has a second sealing portion 420. The outer side wall of the second sealing portion 420 is in interference fit with the wall of the inner cavity 110. The second sealing portion 420 is also in interference fit with the wiping assembly 300. In this way, the sealing of the position where the wiping assembly 300 is located can be achieved.
[0050] In the electronic pen of the present utility model, the electronic assembly is disposed in the storage cavity 401 of the seal 400 and is exposed through the through hole 404 of the seal 400 and the relief opening 111 of the pen tube 100. Alternatively, the electronic assembly is disposed in the storage cavity 401 of the seal 400 and extends out of the pen tube 100 through the through hole 404 of the seal 400 and the relief opening 111 of the pen tube 100, which is convenient for the user to use. Among them, the seal 400 is disposed in the inner cavity 110 of the pen tube 100 and is in interference fit with the wall of the inner cavity 110. A seal is formed between the seal 400 and the wall of the inner cavity 110, and the seal 400 is also in interference fit with the electronic assembly to achieve sealing. In this way, the sealing treatment of the positions of the electronic assembly and the relief opening 111 can be achieved, and the risk of dust or water penetrating into the interior of the electronic pen can be effectively reduced.
[0051] Combined with Figure 3 、 Figure 5 and Figure 6 shown, in some embodiments, the outer side wall of the first sealing portion 410 has a first sealing protrusion 411 disposed around the outer periphery of the first through hole 402. The first sealing protrusion 411 surrounds the inner end of the first relief opening 120, and the first sealing protrusion 411 is in interference fit with the wall of the inner cavity 110.
[0052] Specifically, the first sealing protrusion 411 can be in a runway shape or an annular shape. The first sealing protrusion 411 is formed on the outer sidewall of the first sealing portion 410 and is disposed around the outer periphery of the first through hole 402. Moreover, the first sealing protrusion 411 is disposed around the inner end of the first relief opening 120 and is in interference fit with the wall of the inner cavity 110.
[0053] It can be understood that the interference fit between the first sealing protrusion 411 and the wall of the inner cavity 110 of the pen tube 100 can further improve the sealing effect. Moreover, when external water or dust enters the electronic pen through the first relief opening 120, due to the existence of the first sealing protrusion 411, the risk that water or dust continues to penetrate deep into the electronic pen along the gap between the outer wall of the first sealing portion 410 and the inner wall of the pen tube 100 can be reduced.
[0054] Combined with Figure 3 、 Figure 5 and Figure 6 as shown, further, the inner sidewall of the first sealing portion 410 has a second sealing protrusion 412 disposed around the outer periphery of the first through hole 402, and the second sealing protrusion 412 is in interference fit with the interface 200.
[0055] It can be understood that the interference fit between the second sealing protrusion 412 and the interface 200 can further improve the sealing effect. Moreover, when external water or dust enters the electronic pen through the first relief opening 120 and the first through hole 402, due to the existence of the second sealing protrusion 412, the risk that water or dust continues to penetrate deep into the electronic pen along the gap between the second sealing portion 420 and the interface 200 can be reduced.
[0056] Combined with Figure 2 and Figure 3 , specifically, the interface 200 includes an interface seat 210 and connection terminals 220 disposed in the interface seat 210. The interface seat 210 has a protective side plate 211. The protective side plate 211 is disposed around the connection terminals 220 and is spaced apart from the connection terminals 220. The connection terminals 220 are disposed opposite to the first relief opening 120; the second sealing protrusion 412 is in interference fit with one end of the protective side plate 211 close to the first relief opening 120.
[0057] It can be understood that the interface 200 on the electronic pen can be a USB interface such as Type-A, Type-B, Type-C, etc. After the interface on the charging cable adapted thereto is inserted into the interface 200 on the electronic pen, the protective side plate 211 surrounds the interface on the charging cable; by making the second sealing protrusion 412 in interference fit with one end of the protective side plate 211 close to the first relief opening 120, the interference of the second sealing protrusion 412 on the insertion of the interface on the charging cable can be avoided.
[0058] Specifically, an extension portion 413 is formed on the inner wall of the first sealing portion 410. The extension portion 413 is disposed around the outer periphery of the first through hole 402 and extends toward the protective side plate 211. The second sealing protrusion 412 is formed on the side of the extension portion 413 close to the protective side plate 211.
[0059] Combined Figure 2 with Figure 6 , further, the outer side wall of the seal 400 has a plurality of third sealing protrusions 430. The third sealing protrusions 430 extend along the circumferential direction of the pen tube 100 and are arranged in a ring shape. The plurality of third sealing protrusions 430 are arranged at intervals along the length direction of the pen tube 100. The first through hole 402 is located between two adjacent third sealing protrusions 430, and the third sealing protrusions 430 are in interference fit with the wall of the inner cavity 110.
[0060] It can be understood that the third sealing protrusions 430 can further enhance the sealing effect. Specifically, when external water or dust enters the electronic pen through the first relief opening 120, due to the existence of the third sealing protrusions 430, the risk that water or dust continues to move along the length direction of the pen tube 100 along the gap between the outer wall of the seal 400 and the inner wall of the pen tube 100 and penetrates into the interior of the electronic pen can be further reduced.
[0061] As Figure 2 shown, in some embodiments, the wiping assembly 300 can perform axial movement relative to the pen tube 100.
[0062] Specifically, a key 600 is disposed in the storage cavity 401 of the seal 400. The key 600 is disposed opposite to the wiping assembly 300. When the wiping assembly 300 is pressed against the screen of an electronic device communicatively connected to the electronic pen, the wiping assembly 300 moves axially closer to the key 600 and presses the key 600, thereby triggering relevant signals to wipe the graphics or text on the screen. When the force pressing the wiping assembly 300 disappears, the key 600 rebounds, so that the wiping assembly 300 moves in the reverse direction and resets.
[0063] Combined Figure 2 、 Figure 4 and Figure 5 , specifically, the wiping assembly 300 includes a connecting rod 330, a support rod 320 connected to one end of the connecting rod 330, and a wiping head 310 connected to the support rod 320. The end of the connecting rod 330 away from the support rod 320 is disposed opposite to the key 600, and the wiping head 310 is located outside the pen tube 100.
[0064] Further, a main bracket 500 and a bracket 700 connected to the main bracket 500 are also disposed in the storage cavity 401 of the seal 400, and the wiping assembly 300 is supported by the bracket 700.
[0065] As Figure 4 shown, in some embodiments, a positioning groove 301 is provided on the outer sidewall of the wiping assembly 300. The positioning groove 301 is located in the inner cavity 110 of the pen tube 100, and the axial movement direction of the wiping assembly 300 is perpendicular to the depth direction of the positioning groove 301. The second sealing portion 420 has an insertion portion 422 that surrounds and forms a second through hole 403, and the insertion portion 422 is inserted into the positioning groove 301.
[0066] It can be understood that when the insertion portion 422 is inserted into the positioning groove 301, on the one hand, the sealing between the second sealing portion 420 and the wiping assembly 300 can be achieved. When external water or dust enters through the second relief opening 130, the sealing structure between the insertion portion 422 and the wiping assembly 300 can reduce the risk of water or dust penetrating deep into the storage cavity 401 of the seal 400. On the other hand, since the wiping assembly 300 can move axially, when the second sealing portion 420 passes through the positioning groove 301, the insertion portion 422 will undergo elastic deformation when the wiping assembly 300 moves axially. That is, the second sealing portion 420 will not hinder the axial movement of the wiping assembly 300.
[0067] It should be noted that if the positioning groove 301 is not provided on the outer sidewall of the wiping assembly 300 and only the second sealing portion 420 is sleeved on the wiping assembly 300, then when the wiping assembly 300 moves axially, relative sliding and friction will occur between the wiping assembly 300 and the second sealing portion 420, which may cause wear of the second sealing portion 420 and deteriorate the sealing effect.
[0068] Combined with Figure 4 and Figure 6 , further, the insertion portion 422 is provided with a fourth sealing protrusion 421. The protruding direction of the fourth sealing protrusion 421 is parallel to the axial movement direction of the wiping assembly 300, and the fourth sealing protrusion 421 is in interference fit with the sidewall of the positioning groove 301.
[0069] It can be understood that the interference fit between the fourth sealing protrusion 421 and the sidewall of the positioning groove 301 can further improve the sealing effect between the second sealing portion 420 and the wiping assembly 300. Moreover, the protruding direction of the fourth sealing protrusion 421 is parallel to the axial movement direction of the wiping assembly 300. When the wiping assembly 300 moves axially, the force applied by the wiping assembly 300 to the fourth sealing protrusion 421 is parallel to the protruding direction of the fourth sealing protrusion 421, and no relative sliding occurs between the wiping assembly 300 and the fourth sealing protrusion 421, which can reduce the risk of wear of the fourth sealing protrusion 421.
