Detailed Implementation

[0028] See Figures 1-9 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a pen body 1 and a main support 2. The main support 2 is snapped into the pen body 1. The main support 2 has a semi-open structure and includes a front section 21 and a rear section 22. A front support 3 is snapped onto the front section 21, and a rear support 4 is snapped onto the rear section 22. A drop-proof pen tip assembly 9 is snapped onto the front end of the main support 2. A main board 5 is disposed inside the main support 2. A first fixing edge 51 protrudes from one side of the front end of the main board 5, a second fixing edge 52 protrudes from the middle of the other side of the main board 5, and a third fixing edge 53 protrudes from the rear end of the main board 5 on the same side as the second fixing edge 52. A first fixing groove 31 is opened in the middle of the front support 3 to match the first fixing edge 51, and a second fixing groove 221 is opened in the middle of the rear section 22. The third fixing groove 222 matches the second fixing edge 52 and the third fixing edge 53 respectively. In this embodiment, there are three fixing structures inside the pen body, namely the main bracket, the front bracket and the rear bracket. The three brackets fix the motherboard inside. Three fixing edges are set on both sides of the motherboard. The first fixing edge engages with the first fixing groove of the front bracket, and the length of the first fixing edge is close to the length of the front bracket. Therefore, the front section has a good fixing and protection effect on the motherboard. The middle and rear sections of the motherboard adopt segmented fixing edges that engage with the main bracket and the rear bracket, which also have a good fixing effect. Therefore, the motherboard can be effectively prevented from shaking and shifting when collision or impact occurs, thereby effectively improving the drop resistance of the capacitive pen, making the capacitive pen more durable, longer in service life, and bringing a better user experience.

[0029] More specifically, the main bracket 2 has a bracket buckle groove 23 on the side facing away from the opening in the middle, and a motherboard mounting groove 24 is provided in the center of the inner side of the main bracket 2 to engage with the motherboard 5. The motherboard mounting groove is provided on the inner side of the main bracket for the installation of the motherboard. Together with the front and rear brackets, the motherboard is fixed on both sides, effectively preventing the motherboard from moving when it is impacted, and playing a protective role.

[0030] More specifically, the main bracket 2 has four connection holes 233 on the rear end facing the rear bracket 4, which are used for the installation and fixing of the rear bracket.

[0031] More specifically, the front end of the bracket 21 is provided with a conical mounting cavity 212, and a U-shaped button groove is opened in the middle of the bracket 21 to form a pressing spring 211. A silicone button cap 7 is provided on the outside of the pressing spring 211. In this embodiment, in order to improve the waterproof performance of the capacitive pen, a silicone button cap is used in conjunction with the button. The pressing spring is provided in the front end of the bracket to constrain the silicone button cap, so that the silicone button cap will be continuously subjected to the outward pushing force of the pressing spring, and tightly abut against the pen body, thereby achieving a better sealing and waterproof effect.

[0032] More specifically, the front section 21 of the bracket is provided with a shielding sleeve 6 on its outer side. The shielding sleeve 6 is provided with a button groove 61 that cooperates with the silicone button cap 7. In this embodiment, the shielding sleeve is used to shield the signal and prevent signal interference to the internal components of the capacitive pen. At the same time, the button groove on the shielding sleeve and the silicone button cap are tightly fitted to ensure the waterproof effect.

[0033] More specifically, the front bracket 3 is a semi-circular bracket with a semi-circular locking plate 33 at the front end that avoids inward and engages with the mounting cavity 212. A front buckle 32 is provided on the inner side of the rear end of the front bracket 3, and the front buckle 32 matches and engages with the bracket buckle groove 23. In order to achieve a firm connection between the front bracket and the main bracket, a semi-circular locking plate is provided at the front end of the front bracket. The locking plate is inserted into the mounting cavity for limiting, while the front buckle engages with the bracket buckle groove. Both ends are firmly fixed to the main bracket, thereby constraining and fixing the motherboard.

[0034] More specifically, the rear bracket 4 is a semi-circular bracket with two motherboard clips 41 spaced apart on its inner side, which cooperate with the end of the motherboard 5. The motherboard is inserted between the two motherboard clips. The rear bracket 4 has four connecting posts 42 on its inner side, which match and are fixed to the connecting holes 233. The front end of the motherboard clip 41 has a breathing light hole 43. The breathing light hole 43 is a non-through hole, and the outer wall of the breathing light hole 43 is polished into a transparent sheet. In this embodiment, the breathing light hole corresponds to the breathing light set on the motherboard. To ensure the waterproof effect, the breathing light hole is set as a non-through hole structure, and the outermost part is polished to form a transparent sheet, so as not to affect the light transmission effect while being waterproof.

[0035] More specifically, the motherboard 5 has a recessed section in the middle, where a rechargeable battery 8 is installed and electrically connected to the motherboard 5. A button is located on one side of the front end of the motherboard 5, which contacts a pressing spring 211. By placing the rechargeable battery in the recessed position in the middle of the motherboard, the center of gravity of the motherboard is located at the front end, which is constrained by the large area of ​​the front bracket and the main bracket, ensuring the protective effect. The button on the side of the motherboard contacts the pressing spring. When the silicone button cap is pressed, it pushes the pressing spring to act on the button, thereby performing the specific function operation. While obtaining the normal button operation feel, it can also obtain the rebound feedback feel of the spring, and the rebound of the pressing spring has a better waterproof effect.

[0036] More specifically, a charging hole is provided on one side of the end of the pen body 1, and a sealing cover 10 is provided inside the charging hole, which corresponds to the charging port on the motherboard 5. By setting the sealing cover, the charging port is waterproofed and sealed, thereby improving the waterproof performance of the capacitive pen.

[0037] More specifically, the shock-resistant pen tip assembly 9 includes a conical hollow silicone pen tip 91, an optical sensor assembly 92, a pressure sensing coil 93, and a pen tip fixing rod 95. The front end of the optical sensor assembly 92 is fitted inside the conical hollow silicone pen tip 91, and the rear end of the optical sensor assembly 92 is fitted onto the front end of the pen tip fixing rod 95. The pressure sensing coil 93 is disposed on the outer layer of the optical sensor assembly 92 and fixed to the inner wall of the mounting cavity 212. A spring 94 is provided at the rear end of the pen tip fixing rod 95 to abut against the main board 5. In this embodiment, the shock-resistant pen tip assembly adopts a multi-stage structure, which can have a better shock filtering effect when subjected to impact. Therefore, compared with traditional pens... The pointed structure offers better drop resistance. The tip itself is a conical hollow silicone nib, protecting the internal optical sensor components. The silicone material fits tightly with the mounting cavity at the front of the main support, providing excellent waterproofing. The pressure-sensing coil, positioned in the center of the assembly, is wound in a conical shape and contacts the inner wall of the mounting cavity to prevent lateral movement. Its lead wire is fixed to the optical sensor assembly's mounting rod and electrically connected to the main board. A spring, in contact with the nib mounting rod and the main board, provides deformation conditions for the entire nib assembly, working in conjunction with the pressure-sensing coil to detect pressure and achieve optimal writing and protection.

[0038] The working principle of this utility model is as follows: The front bracket 3 engages with the bracket buckle groove 23 in the middle of the main bracket 2 via the front buckle 32, while the semi-circular buckle plate 33 at the front end engages into the mounting cavity 212 of the main bracket 2, thus achieving a firm connection between the front bracket 3 and the main bracket 2. The first fixing edge 51 on one side of the front end of the motherboard 5 engages into the first fixing groove 31 of the front bracket 3, and the other side of the motherboard 5 is installed in the motherboard mounting groove 24 of the main bracket 2, thus achieving the installation and fixation of the front section of the motherboard 5. The fixing of the motherboard 5 through the groove structure on both sides can effectively prevent the motherboard from vibrating and displacing during collisions, thereby providing good protection for the motherboard. The rear section of the motherboard 5 is fastened by the engagement of the second fixing edge 52 and the third fixing edge 53 with the second fixing groove 221 and the third fixing groove 222. At the same time, the rear bracket 4 engages with the main bracket 2 via the connecting post engaging into the connecting hole, thus achieving the connection between the rear bracket 4 and the main bracket 2. The bracket 2 securely connects to firmly fix the motherboard 5. The anti-drop pen tip assembly 9 places the front end of the optical sensor assembly 92 in the hollow silicone pen tip 91, ensuring the sensing effect while effectively protecting the sensor. The anti-drop pen tip assembly 9 has a multi-segment structure, with the rear end further cushioned by a spring 94, providing good cushioning protection when the pen tip is impacted. In addition, the silicone material also has good waterproof performance. The pen body 1 uses a silicone button cap 7 as a button pressing component, which abuts against the pressing spring 211 and is continuously subjected to the reaction force of the pressing spring 211. When not in use, it will remain pressed outward, thus achieving a waterproof seal. The rear of the pen body 1 is sealed with a sealing cover 10 to waterproof the charging port, thus achieving overall waterproofing. This makes the capacitive pen both waterproof, drop-resistant, and durable.
