[0034] In the related art, the stylus pen 10 includes a pen tip 700 and a pen body 100, and electrodes for transmitting and receiving signals are provided at the pen tip 700, so that the stylus pen 10 can be used in conjunction with an electronic device. The electronic device may be a tablet, a computer, or a mobile phone. Among them, the specific structure of the electrode provided at the pen tip 700 is as follows: the stylus pen 10 includes a metal rod and a metal electrode. Since there is a gap between the metal electrode and the metal rod, when the user uses the stylus pen 10 to draw, click, or write on the electronic device, an abnormal sound will be emitted at the pen tip 700, thereby affecting the user's experience. To this end, the present application proposes a stylus pen 10.

[0035] Please refer to Figures 1 to 5 In some embodiments, the stylus pen 10 includes: a pen body 100, a circuit board 200, a second electrode 300, a first electrode 400 and a filler 600. The pen body 100 is provided with a storage cavity 110, in which electronic components can be placed, so that the stylus pen 10 can be used with an electronic device. The electronic device can be a laptop, a mobile phone or a tablet, etc. The pen body 100 can also be held by the user, so as to facilitate the user's use. The circuit board 200 is arranged in the storage cavity 110. After the second electrode 300 is connected to the circuit board 200, the second electrode 300 can receive the signal of the electronic device, thereby transmitting it to the electronic components on the circuit board 200, so as to realize the coordination between the stylus pen 10 and the electronic device. In addition to the second electrode 300, the stylus pen 10 can also include a second electrode, which can be used to send a signal. Similarly, after the first electrode 400 is connected to the circuit board 200, the first electrode 400 can send a signal, so as to realize the coordination between the stylus pen 10 and the electronic device. Among them, this part belongs to the prior art and will not be described in detail here. The second electrode 300 includes a first portion 310 and a second portion 320 connected to each other. The first portion 310 protrudes out of the storage cavity 110, and the second portion 320 is disposed in the storage cavity 110. The second electrode 300 is provided with a first through hole 330, that is, the first portion 310 and the second portion 320 are provided with a penetrating first through hole 330. The first electrode 400 includes a third portion 410 and a fourth portion 420 connected to each other, the third portion 410 protrudes out of the first through hole 330 and the storage cavity 110, and the fourth portion 420 is disposed in the first through hole 330, that is, the first electrode 400 passes through the first through hole 330, so that at least parts of the first electrode 400 and the second electrode 300 are both located in the storage cavity 110, and the length of the third portion 410 may be greater than the length of the first portion 310. There is a first gap 500 between the first electrode 400 and the first portion 310, that is, the fourth portion 420 is located in the first through hole 330 and there is a first gap 500 between the fourth portion 420 and the hole wall of the first through hole 330. Due to the existence of the first gap 500, when the stylus pen 10 is in use, an abnormal sound will be emitted from the pen tip 700. The first gap 500 can be specifically referred to Figure 2The filling member 600 is disposed in the first gap 500. For details, please refer to Figure 3 Specifically, after the filler 600 is disposed between the first electrode 400 and the first portion 310, two sides of the filler 600 can abut against the first electrode 400 and the first portion 310, respectively, which can effectively prevent the pen tip 700 from making an abnormal sound. Specifically, the stylus pen 10 can effectively prevent the pen tip 700 from making an abnormal sound.

[0036] For further information, please refer to Figure 3 In some embodiments, the stylus pen 10 further includes a pen tip 700. The pen tip 700 is made of plastic material, and is provided with a first groove 710 and a second groove 720. The first part 310 is provided in the second groove 720, and the third part 410 is provided in the first groove 710. The pen tip 700 can wrap up the part of the second electrode 300 protruding from the storage cavity 110, that is, wrap up the first part 310. The pen tip 700 can also wrap up the part of the first electrode 400 protruding from the storage cavity 110, that is, wrap up the third part 410. The head of the pen tip 700 is set to a cone shape, which can improve the writing experience of the user. In addition, the material of the pen tip 700 can be rubber material. The pen tip 700 made of rubber material is soft, soft to the touch, smoother to use, and will not scratch the screen surface.

[0037] Furthermore, when installing the stylus pen 10, after the second electrode 300 and the first electrode 400 are installed, a first gap 500 is formed between the second electrode 300 and the first electrode 400. At this time, the filler 600 needs to be installed in the first gap 500, so as to effectively avoid abnormal noise between the second electrode 300 and the first electrode 400. The filler 600 may be in the shape of a circular ring. When installing the filler 600, the filler 600 and the pen tip 700 may be connected, so that the pen tip 700 and the filler 600 are installed together, which can improve the installation efficiency. Therefore, please refer to Figure 3 In some embodiments, the pen tip 700 is connected to the filling piece 600, and the filling piece 600 is located between the first groove 710 and the second groove 720 to separate the first groove 710 and the second groove 720 from each other. Specifically, after the filling piece 600 is connected to the pen tip 700, on the one hand, it is not only convenient to install and improve the installation efficiency, but also on the other hand, after the filling piece 600 separates the first groove 710 and the second groove 720, the filling piece 600 can also separate the second electrode 300 and the first electrode 400, that is, the filling piece 600 is in the first gap 500 between the first part 310 and the third part 410.

[0038] Furthermore, there are two ways to connect the pen tip 700 to the filling piece 600. One is to connect the pen tip 700 and the filling piece 600 by bonding after the pen tip 700 and the filling piece 600 are manufactured separately; the other is to directly manufacture the pen tip 700 and the filling piece 600 by an integrated molding process, wherein the integrated molding process can improve the manufacturing efficiency, and the pen tip 700 and the filling piece 600 manufactured by the integrated molding process have higher strength and are not easily damaged. Therefore, in some embodiments, the pen tip 700 and the filling piece 600 are an integrated structure.

[0039] In some embodiments, the size of the first gap 500 is 0.02 mm to 0.05 mm. The size of the first gap 500 can be 0.02 mm, 0.03 mm or 0.05 mm, that is, when the filler 600 is in a circular ring shape, the thickness of the filler 600 is 0.02 mm, 0.03 mm or 0.05 mm. The first gap 500 can prevent the first electrode 400 from contacting the second electrode 300, but the first gap 500 can cause abnormal noise. Therefore, the first gap 500 cannot be too large or too small. When the size of the first gap 500 is 0.02 mm to 0.05 mm, it can effectively avoid abnormal noise and short circuit between the first electrode 400 and the second electrode 300.

[0040] In some embodiments, the material of the filling piece 600 is an elastic material. After the filling piece 600 is arranged in the first gap 500, the filling piece 600 can effectively avoid the occurrence of abnormal noise. In order to achieve a good filling effect of the filling piece 600, the material of the filling piece 600 can be an elastic material, which can make the filling piece 600 tightly inserted into the first gap 500 to avoid looseness. The elastic material can be thermoplastic polyurethane elastomer, polyurethane, rubber or styrene-based thermoplastic elastomer, etc.

[0041] For further information, please refer to Figure 3In some embodiments, the stylus pen 10 further includes a bracket 800, which is disposed in the storage cavity 110, and the two sides of the second electrode 300 are respectively in contact with the bracket 800 and the cavity wall of the storage cavity 110. Specifically, the bracket 800 can assist in the installation of the second electrode 300, thereby facilitating the installation of the second electrode 300 in the storage cavity 110. That is, when installing the second electrode 300, the second electrode 300 is sleeved on the outside of the bracket 800, and then the bracket 800 and the second electrode 300 can be placed in the storage cavity 110 for installation. In addition, the bracket 800 can also play a role in fixing the second electrode 300, thereby effectively preventing the second electrode 300 from moving. Specifically, after the second electrode 300 is sleeved on the outside of the bracket 800, the shape of the bracket 800 can be adapted to the shape of the pen body 100, and then, by pressing the bracket 800, the two sides of the second electrode 300 can be respectively in contact with the bracket 800 and the cavity wall of the storage cavity 110, thereby fixing the second electrode 300.

[0042] Further, the following describes how the second electrode 300 is installed on the bracket 800. Figure 3 In some embodiments, the second electrode 300 includes a first body portion 321 and a first protruding portion 322. Specifically, the second portion 320 includes a first body portion 321 and a first protruding portion 322. The first protruding portion 322 is connected to the first body portion 321, and the first protruding portion 322 protrudes relative to the first body portion 321. The bracket 800 is provided with a slot, and the first protruding portion 322 is engaged in the slot. Specifically, after the first protruding portion 322 is engaged in the slot, the second electrode 300 can be fixed on the bracket 800, which can effectively prevent the second electrode 300 from moving.

[0043] Further, the following describes how the second electrode 300 is electrically connected to the circuit board 200. Figure 3 and Figure 4 In some embodiments, the stylus pen 10 further includes a first connector 1000, one end of which is sleeved on the outside of the bracket 800 and abuts against the second electrode 300, and the other end of the first connector 1000 is connected to the circuit board 200. The specific manner in which one end of the first connector 1000 is sleeved on the outside of the bracket 800 can be that the first connector 1000 is a metal wire, one end of the metal wire is wound around the outside of the bracket 800, and then the second electrode 300 is sleeved on the outside of the bracket 800, so that the metal wire abuts against the second electrode 300, which can realize the electrical connection between the second electrode 300 and the first connector 1000. Then, the other end of the first connector 1000 is welded on the circuit board 200, so that the second electrode 300 and the circuit board 200 can be electrically connected.

[0044] Further, the following describes how the first electrode 400 is electrically connected to the circuit board 200. Figure 3 and Figure 5 In some embodiments, the stylus pen 10 further includes a second connector 1100. The material of the second connector 1100 may be a conductive material. The bracket 800 is provided with a second through hole 820, the first electrode 400 is provided in the second through hole 820, and the two ends of the second connector 1100 are electrically connected to the first electrode 400 and the circuit board 200, respectively. After the first electrode 400 passes through the second through hole 820, the distance between the second connector 1100 and the first electrode 400 can be shortened, so as to facilitate the second connector 1100 to connect the first electrode 400 and the circuit board 200, respectively. Among them, after the first electrode 400 is electrically connected to the circuit board 200 through the second connector 1100, the first electrode 400 can send a signal to the circuit board 200 for processing.

[0045] Further, after the first electrode 400 passes through the second through hole 820, the first electrode 400 needs to be fixed to prevent the first electrode 400 from being displaced. Specifically, this can be done by fixing the first electrode 400 through the intermediate piece 900. Therefore, please refer to Figure 3 and Figure 5 In some embodiments, the stylus pen 10 further includes an intermediate piece 900. The intermediate piece 900 is provided with a mounting hole 910, the bracket 800 is provided with a third through hole 830 communicating with the second through hole 820, the intermediate piece 900 is disposed in the third through hole 830, and one end of the fourth portion 420 away from the third portion 410 is disposed in the mounting hole 910. One end of the second connecting piece 1100 is sleeved on the outside of the intermediate piece 900, and the other end of the second connecting piece 1100 is electrically connected to the circuit board 200. Specifically, the material of the intermediate piece 900 can be a conductive material, and the intermediate piece 900 can be snapped into the mounting hole 910 to complete the fixation. After the intermediate piece 900 is fixed, the first electrode 400 can be snapped into the mounting hole 910, which can complete the fixation of the first electrode 400. The second connector 1100 may be a metal wire, one end of which is wound around the outside of the middle piece 900, thereby achieving direct electrical connection between the second connector 1100 and the middle piece 900, and achieving indirect electrical connection between the first electrode 400 and the second connector 1100. Afterwards, the second connector 1100 is electrically connected to the circuit board 200, so that the circuit conduction between the first electrode 400 and the circuit board 200 can be completed.

[0046] Furthermore, the bracket 800 mentioned above is provided with a second through hole 820. When the first electrode 400 is provided in the second through hole 820, there will be a second gap between the first electrode 400 and the hole wall of the second through hole 820. The existence of the second gap will cause friction between the first electrode 400 and the hole wall of the second through hole 820. When the first electrode 400 and the hole wall of the second through hole 820 generate friction, this will affect the force transmission of the pen tip 700 during the writing process and affect the pressure sensing of the pressure sensor in the stylus 10. Therefore, the above problem can be solved by making the first electrode 400 abut against the hole wall of the second through hole 820. For details, please refer to Figure 3 In some embodiments, the fourth portion 420 includes a second body portion 421 and a second protruding portion 422. The second protruding portion 422 is connected to the second body portion 421, and the second protruding portion 422 protrudes relative to the second body portion 421, and the second protruding portion 422 abuts against the hole wall of the second through hole 820. In this way, after the second protruding portion 422 abuts against the hole wall of the second through hole 820, this can effectively reduce the friction between the first electrode 400 and the hole wall of the second through hole 820.

[0047] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
