[0039] Figure 1 、 Figure 2 and Figure 5 Figs.

[0040] As shown in Figure 2 , the pen body 100 is a hollow structure, and the tail end of the pen body 100 is open. Among them, the pen body 100 can be a circular tubular structure, a square tubular structure, or other shaped structures. The pen body 100 is for the user to hold so that the user can use the electronic pen.

[0041] Combined with Figure 2 and Figure 3 , the support assembly 300 is disposed inside the pen body 100. The support assembly 300 is a hollow structure, and one end of the support assembly 300 close to the tail end of the pen body 100 has an opening 310.

[0042] It can be understood that the support assembly 300 is a hollow structure with an opening 310. The support assembly 300 is fixed inside the pen body 100, and the opening 310 faces the tail end of the pen body 100. The support assembly 300 is used to provide support for, including but not limited to, the tail assembly 200.

[0043] Combined with Figure 2 and Figure 3 , the tail assembly 200 has a connecting shaft 210. The connecting shaft 210 passes through the support assembly 300, and the connecting shaft 210 extends from the inside of the support assembly 300 through the opening 310 to the outside of the support assembly 300. Among them, the connecting shaft 210 is configured to be able to move relative to the support assembly 300 along the length direction of the pen body 100.

[0044] It can be understood that the internal space of the bracket assembly 300 provides a moving space for the movement of the connecting shaft 210. The connecting shaft 210 can move relative to the bracket assembly 300 along the length direction of the pen body 100, where the length direction of the pen body 100 also refers to the axial direction of the pen body 100. One end of the connecting shaft 210 extending to the outside of the bracket assembly 300 is used to connect the pen tail piece 220. At least a part of the pen tail piece 220 is located at the rear side of the tail end of the pen body 100. Pressing the pen tail piece 220 can cause the connecting shaft 210 to move along the length direction of the pen body 100.

[0045] Furthermore, the pen tail piece 220 is provided with an assembly hole 221, and the connecting shaft 210 passes through the assembly hole 221 so that the connecting shaft 210 is connected to the pen tail piece 220.

[0046] Among them, the connecting shaft 210 and the pen tail piece 220 can be connected by an interference fit method, the connecting shaft 210 and the pen tail piece 220 can also be connected by a threaded connection method, and the connecting shaft 210 and the pen tail piece 220 can also be bonded together.

[0047] It should be noted that a part of the pen tail piece 220 is located inside the pen body 100, and another part extends from the tail end of the pen body 100. The pen tail piece 220 can cover the tail end of the pen body 100, reducing the risk of external contaminants directly entering the inside of the pen body 100.

[0048] As Figure 2 shown, it should be noted that the electronic pen further includes a switch 500 disposed inside the bracket assembly 300. The connecting shaft 210 can move relative to the bracket assembly 300 along the length direction of the pen body 100, so as to switch between the initial position and the trigger position; when the connecting shaft 210 is in the initial position, the switch 500 is not triggered by the connecting shaft 210; when the connecting shaft 210 is in the trigger position, the switch 500 is triggered by the connecting shaft 210.

[0049] It can be understood that when the connecting shaft 210 is in the initial position, the connecting shaft 210 is spaced apart from the switch 500. At this time, the connecting shaft 210 cannot touch the switch 500. Among them, the switch 500 is located on the moving path of the connecting shaft 210. When the connecting shaft 210 moves to the trigger position, the connecting shaft 210 will squeeze the switch 500, so that the switch 500 is triggered.

[0050] In some embodiments, the function of switch 500 is to determine whether to execute the erasing function of the electronic pen. Specifically, when the electronic pen is currently performing the writing function, if switch 500 is triggered once, the electronic pen will execute the erasing function; if switch 500 is triggered a second time, the electronic pen will cancel the execution of the erasing function and then execute the writing function. In other embodiments, when switch 500 is not triggered, the electronic pen executes the writing function; when switch 500 is continuously triggered, the electronic pen executes the erasing function.

[0051] In still other embodiments, the function of switch 500 is to adjust the width of the writing line. In yet other embodiments, the function of switch 500 is to adjust the font of the writing.

[0052] Combined with Figure 2 and Figure 4 , it should be noted that the electronic pen further includes a circuit board 510. The switch 500 is disposed on the circuit board 510, and the circuit board 510 is used to connect the switch 500 to the main board of the electronic pen.

[0053] Combined with Figure 2 and Figure 3 , the electronic pen further includes a seal 400. The seal 400 is used to seal the gap between the connecting shaft 210 and the wall of the opening 310, thereby preventing external contaminants, such as water, dust, etc., from entering the bracket assembly 300 and damaging the components inside the bracket assembly 300. At the same time, it can also prevent external contaminants from entering the bracket assembly 300 and further penetrating into the interior of the electronic pen to damage other components.

[0054] As Figure 4 shown, specifically, the seal 400 has an elastic sealing portion 410. The elastic sealing portion 410 has an open structure at both ends and is hollow inside. The elastic sealing portion 410 is sleeved outside the connecting shaft 210. The first end 410a of the elastic sealing portion 410 is sleeved on the connecting shaft 210, and the second end 410b of the elastic sealing portion 410 is connected around the opening 310. The elastic sealing portion 410 is used to seal the opening 310.

[0055] It should be noted that the material of the elastic sealing part 410 is silicone, rubber or other elastic materials; the first end 410a of the elastic sealing part 410 is sleeved on the connecting shaft 210 to achieve the seal between the first end 410a of the elastic sealing part 410 and the outer side wall of the connecting shaft 210; the second end 410b of the elastic sealing part 410 is connected around the opening 310 to achieve the seal between the second end 410b of the elastic sealing part 410 and the edge of the opening 310; thus, the elastic sealing part 410 can seal the opening 310, thereby preventing external pollutants from entering the bracket assembly 300 and damaging the devices inside the bracket assembly 300. At the same time, it can also prevent external pollutants from entering the bracket assembly 300 and further penetrating into the interior of the electronic pen to damage other devices.

[0056] It can be understood that in the present utility model, the elastic sealing part 410 is an elastic structure. Therefore, the elastic sealing part 410 will not interfere with the movement of the connecting shaft 210 relative to the bracket assembly 300 along the length direction of the pen body 100, ensuring the normal operation of the connecting shaft 210.

[0057] Specifically, the first end 410a of the elastic sealing part 410 is configured to be able to move with the connecting shaft 210; when the connecting shaft 210 moves relative to the bracket assembly 300 along the length direction of the pen body 100, due to the elastic structure of the elastic sealing part 410, the connecting shaft 210 can drive the first end 410a of the elastic sealing part 410 to move, causing the overall elastic deformation of the elastic sealing part 410. In addition, after the connecting shaft 210 moves relative to the bracket assembly 300 along the length direction of the pen body 100 and deviates from the initial position, the acting force exerted by the elastic sealing part 410 on the connecting shaft 210 makes the connecting shaft 210 have a tendency to return to the initial position, that is, the elastic sealing part 410 can reset the connecting shaft 210.

[0058] More specifically, the connecting shaft 210 can move relative to the bracket assembly 300 along the length direction of the pen body 100, so as to switch between the initial position and the trigger position; wherein, when the connecting shaft 210 is in the initial position, the switch 500 is not triggered by the connecting shaft 210; when the connecting shaft 210 is in the trigger position, the switch 500 is triggered by the connecting shaft 210; when the switch 500 is in the trigger position, the acting force exerted by the elastic sealing part 410 on the connecting shaft 210 makes the connecting shaft 210 have a tendency to return to the initial position.

[0059] In summary, the elastic sealing part 410 of the present utility model not only has the function of sealing the opening 310, but also has the function of promoting the reset of the connecting shaft 210.

[0060] Such as Figure 4As shown, further, the elastic sealing portion 410 is located outside the bracket assembly 300 and near one end of the bracket assembly 300 having an opening 310. There is an annular gap 430 formed around the connecting shaft 210 between the elastic sealing portion 410 and the connecting shaft 210. The second end 410b of the elastic sealing portion 410 is spaced from the connecting shaft 210 through the annular gap 430.

[0061] It can be understood that the elastic sealing portion 410 is located outside the opening 310. The second end 410b of the elastic sealing portion 410 is fixedly connected around the opening 310. The first end 410a of the elastic sealing portion 410 is fixedly sleeved around the connecting shaft 210. Among them, an annular gap 430 is formed between the elastic sealing portion 410 and the connecting shaft 210 around the connecting shaft 210. The annular gap 430 gives the first end 410a of the elastic sealing portion 410 space to move along the length direction of the pen body 100 relative to the bracket assembly 300 following the connecting shaft 210. In addition, when the pen tail piece 220 is pressed so that the connecting shaft 210 is pressed, the connecting shaft 210 will drive the elastic sealing portion 410 to be compressed. When the pressing force on the pen tail piece 220 is released, the elastic sealing portion 410 will drive the connecting shaft 210 to reset under the action of its own elastic force.

[0062] In some embodiments, the cross-sectional area of the internal space of the elastic sealing portion 410 gradually increases from the first end 410a to the second end 410b direction, where the cross-section of the elastic sealing portion 410 is perpendicular to the axis of the connecting shaft 210. Thus, after the elastic sealing portion 410 is sleeved on the connecting shaft 210, an annular gap 430 will be formed between the elastic sealing portion 410 and the connecting shaft 210 around the connecting shaft 210.

[0063] Specifically, the elastic sealing portion 410 is a conical structure.

[0064] As Figure 4 shown, in some embodiments, a positioning groove 320 is provided on the peripheral edge of the opening 310, and the second end 410b of the elastic sealing portion 410 is disposed in the positioning groove 320.

[0065] It can be understood that the positioning groove 320 is a ring-shaped structure. The positioning groove 320 surrounds the opening 310, and the second end 410b of the elastic sealing portion 410 is disposed in the positioning groove 320.

[0066] It should be noted that, in some embodiments, the second end 410b of the elastic sealing portion 410 is fixed to the edge of the opening 310 with glue; in other embodiments, the seal 400 is directly injection-molded on the bracket assembly 300 so that the second end 410b of the elastic sealing portion 410 is fixedly connected to the bracket assembly 300.

[0067] AsFigure 3 , Figure 6 and Figure 7 As shown in Figure 3 , Figure 6 and Figure 7 , further, the seal 400 further has a socket portion 420, the socket portion 420 is sleeved outside the connecting shaft 210, and the first end 410a of the elastic sealing portion 410 is sleeved on the socket portion 420.

[0068] It can be understood that the socket portion 420 and the elastic sealing portion 410 are of an integrally formed structure. Among them, by providing the socket portion 420 at the first end 410a of the elastic sealing portion 410 and making the socket portion 420 sleeved outside the connecting shaft 210, it is beneficial to increase the contact area between the seal 400 and the connecting shaft 210, thereby improving the reliability of the connection between the seal 400 and the connecting shaft 210.

[0069] It should be noted that, in some embodiments, the socket portion 420 is sleeved on the connecting shaft 210 by glue; in other embodiments, the seal 400 is directly injection-molded on the connecting shaft 210 by injection molding so that the socket portion 420 is fixedly connected to the connecting shaft 210.

[0070] Further, a positioning step 211 is provided on the outer side wall of the connecting shaft 210, and the socket portion 420 is provided on the positioning step 211.

[0071] Specifically, the connecting shaft 210 includes a large-diameter section and a small-diameter section connected to the large-diameter section. The large-diameter section and the small-diameter section are coaxially arranged. The positioning step 211 is formed between the large-diameter section and the small-diameter section, and the positioning step 211 is used to position the socket portion 420.

[0072] Combined with Figure 2 and Figure 3 , in some embodiments, the electronic pen further includes an auxiliary reset member 600. The auxiliary reset member 600 is provided in the bracket assembly 300. The auxiliary reset member 600 is connected to the connecting shaft 210. The auxiliary reset member 600 is configured to: after the connecting shaft 210 moves relative to the bracket assembly 300 in the length direction of the pen body 100 and deviates from the initial position, apply a force to the connecting shaft 210 to make the connecting shaft 210 have a tendency to return to the initial position.

[0073] It can be understood that when the connecting shaft 210 moves relative to the bracket assembly 300 in the length direction of the pen body 100 and deviates from the initial position, the elastic sealing portion 410 can play a reset role on the connecting shaft 210. By adding the auxiliary reset member 600, the reset speed of the connecting shaft 210 can be further improved. And when the elastic force of the elastic seal 400 is lost, the auxiliary reset member 600 can also play a reset effect on the connecting shaft 210, thereby reducing the risk that the tail assembly 200 cannot be automatically reset.

[0074] ​​​​Specifically, the auxiliary reset member 600 is a spring. One end of the spring abuts against the bracket assembly 300, and the other end of the spring abuts against the abutting portion 212 on the connecting shaft 210. Among them, the abutting portion 212 is arranged on the side wall of the connecting shaft 210.

[0075] Of course, in some other embodiments, the auxiliary reset member 600 can also be an elastic sheet or other elastic members such as elastic rubber.

[0076] As Figure 2 shown, in some embodiments, the electronic pen further includes a sealing ring 700. The sealing ring 700 is sleeved on the bracket assembly 300 and is in interference fit with the inner wall of the pen body 100.

[0077] It can be understood that the sealing ring 700 is used to seal the gap between the bracket assembly 300 and the inner wall of the pen body 100, thereby further improving the sealing effect of the electronic pen. The sealing ring 700 can prevent external pollutants from entering the interior of the electronic pen through the gap between the bracket assembly 300 and the inner wall of the pen body 100 and affecting the internal components of the electronic pen.

[0078] In the electronic pen of the present utility model, the tail assembly 200 is arranged at the tail of the pen body 100, the bracket assembly 300 is arranged inside the pen body 100 and is used to support the tail assembly 200, and the seal 400 is used to seal the gap between the connecting shaft 210 and the wall of the opening 310, thereby preventing external pollutants, such as water, dust, etc., from entering the bracket assembly 300 and damaging the components inside the bracket assembly 300. At the same time, it can also prevent external pollutants from entering the bracket assembly 300 and further penetrating into the interior of the electronic pen to damage other components. Specifically, the first end 410a of the elastic sealing portion 410 of the seal 400 is sleeved on the connecting shaft 210 to achieve the seal between the first end 410a of the elastic sealing portion 410 and the outer side wall of the connecting shaft 210; the second end 410b of the elastic sealing portion 410 is connected around the opening 310 to achieve the seal between the second end 410b of the elastic sealing portion 410 and the edge of the opening 310; in this way, the elastic sealing portion 410 can seal the opening 310, thereby preventing external pollutants from entering the bracket assembly 300 and damaging the components inside the bracket assembly 300. At the same time, it can also prevent external pollutants from entering the bracket assembly 300 and further penetrating into the interior of the electronic pen to damage other components. In addition, the elastic sealing portion 410 is an elastic structure. Therefore, the elastic sealing portion 410 will not interfere with the movement of the connecting shaft 210 relative to the bracket assembly 300 along the length direction of the pen body 100, ensuring the normal operation of the connecting shaft 210.
