[0030] The present utility model will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0031] According to an embodiment of the present utility model, as Figure 1 shown, a capacitive pen includes:
[0032] A pen barrel, with a plug-in portion 1 provided at the end of the pen barrel, and a charging port 2 and a pin 3 provided on the plug-in portion 1;
[0033] A pen cap, which includes an inner cap body 4 and an outer cap shell 5 sleeved on the inner cap body 4, and the outer cap shell 5 can drive the inner cap body 4 to translate and rotate along the axis;
[0034] An L-shaped groove 6 that mates with the pin 3 is formed on the inner cap body 4. The pin 3 is confined within the L-shaped groove 6. When the pen cap is placed on the insertion portion 1, the pen cap is rotated to lock the pin 3 within the L-shaped groove 6, completing the relative fixation of the pen cap and the pen barrel and shielding the charging port 2.
[0035] Different from the prior art, the present utility model shields the charging interface originally provided on the pen barrel of the capacitive pen through the pen cap, improving the waterproof and dustproof performance of the capacitive pen. Even if water is splashed or spilled on the outer surface of the capacitive pen, it will not cause water to enter the charging port 2 and damage it. On the one hand, the waterproof performance of the capacitive pen product itself is improved. On the other hand, the dangerous situation of electric leakage during charging caused by water entering the charging port 2 of the capacitive pen is avoided, improving the safety performance of capacitive pen charging.
[0036] Although there is a similar structure in the prior art that is shielded by the pen cap, the prior art usually uses a magnetic attraction method to cooperate the pen cap and the pen barrel. One drawback of this method is that if the magnetic force is too large, the pen cap and the pen barrel will be too tightly combined, making it inconvenient to remove the pen cap. If the magnetic force is too small, the two will be too loosely combined and the pen cap is likely to fall off. Moreover, the adjustment of the magnetic force requires repeated verification and testing, resulting in relatively high testing and R & D costs. In the present utility model, through the cooperation method of the pin 3 and the L-shaped groove 6, as shown in the figure, the pin 3 is already within the L-shaped groove 6 itself. Moving the pen cap along the long side direction of the L-shaped groove 6 can achieve the covering of the pen cap on the insertion portion 1. When the pen cap completely covers the insertion portion 1, by rotating the pen cap, the pin 3 is limited within the short side of the L-shaped groove 6, completing the relative fixation of the pen cap and the pen barrel.
[0037] Furthermore, in this embodiment, since the pin 3 is always confined within the L-shaped groove 6, the pen cap and the pen barrel will not be completely separated during the charging process. The advantage of this is that it can avoid the loss of the pen cap. Because the size of the pen cap is relatively small, if it is placed casually, it is very likely to be lost. By this method, even during the charging process, the pen cap and the pen barrel will not be completely separated. Compared with the prior art that uses a magnetic attraction method to cooperate the pen cap and the pen barrel, it is less likely to forget or lose the pen cap.
[0038] Further, according to an embodiment of the present utility model, the capacitive pen of this embodiment further includes a spring 7. The spring 7 is arranged at the end of the insertion part 1. When the pen cap covers the insertion part 1, the spring 7 is in a compressed state. By arranging the spring 7, when it is necessary to charge the capacitive pen, when the pen cap is rotated until the pin 3 is within the long side of the L-shaped groove 6, the pen cap can automatically bounce open, exposing the charging port 2. And since the pin 3 is always limited within the L-shaped groove 6, the pen cap will not be directly bounced to be completely separated from the pen barrel. Through the cooperation of the spring 7, the pin 3 and the L-shaped groove 6, while realizing the assisted bounce of the pen cap, it is also ensured that the pen cap is never completely separated from the pen barrel, further improving the charging convenience of the capacitive pen of the present utility model.
[0039] Further, in this embodiment, the pin 3 can also be an elastic pin 3. In the case where the pin 3 is an elastic pin 3, it is convenient to limit the pin 3 within the L-shaped groove 6 when the capacitive pen leaves the factory; at the same time, it also provides a structural basis for the complete separation of the pen cap from the pen barrel.
[0040] Further, in this embodiment, the diameter of the insertion part 1 is smaller than the diameter of the pen barrel, and the diameter of the pen cap is equal to the diameter of the pen barrel. In this way, after the pen barrel and the pen cap are combined, there will be no protrusions or depressions on the outer surface of the capacitive pen as a whole, ensuring the overall beauty of the capacitive pen.
[0041] Further, the pen barrel includes a pen holder 8. A fixed bracket is arranged inside the pen holder 8. A first accommodation cavity for docking the insertion part 1 is formed at the end of the fixed bracket. An annular protrusion is arranged at one end of the insertion part 1 that docks with the pen barrel. The annular protrusion is limited within the first accommodation cavity. By limiting the annular protrusion of the insertion part 1 within the first accommodation cavity of the fixed bracket, the tight combination of the insertion part 1 and the pen barrel is ensured, and it will not be separated from the pen barrel when the capacitive pen falls. This structural design improves the structural integrity of this capacitive pen.
[0042] Further, at least one anti-rolling plane 9 is arranged on the pen holder 8. The pen holder 8 is composed of an arc surface and a horizontal plane, and the horizontal plane is the anti-rolling plane 9. By arranging the anti-rolling plane 9, it can prevent the capacitive pen from rolling and falling when placed casually.
[0043] Further, the pen shaft further includes a pen core module, a battery 13, and a charging module. The fixing bracket includes a first half-clamping portion 15, a second half-clamping portion 16, and a third half-clamping portion 17. In the first half-clamping portion 15, the pen core module is defined within a first clamping cavity formed by the first half-clamping portion 15 and the second half-clamping portion 16, and the charging module is defined within a second clamping cavity formed by the first half-clamping portion 15 and the third half-clamping portion 17. The first half-clamping portion 15 and the third half-clamping portion 17 further form a first accommodation cavity for the clamping stroke. The battery 13 is fixed to the first half-clamping portion 15 and is located between the second half-clamping portion 16 and the third half-clamping portion 17. The pen core module, the battery 13, and the charging module are all fixed within the fixing bracket. The fixing bracket is composed of the first half-clamping portion 15, the second half-clamping portion 16, and the third half-clamping portion 17. After fixing the pen core module, the battery 13, and the charging module through the above three half-clamping portions and then installing them into the pen barrel 8, the integrity of the capacitive pen is effectively improved. The pen core module, the battery 13, and the charging module are all firmly defined in their respective corresponding positions, ensuring the compactness and integrity of the overall structure.
[0044] According to an embodiment of the present invention, the pen core module includes a pen core circuit board 11 and a touch pen core 10. One end of the pen core circuit board 11 is provided with an installation notch 12, and the tail of the touch pen core 10 is provided with an installation boss adapted to the installation notch 12. The installation boss is embedded in the installation notch 12, and the other end of the pen core circuit board 11 is electrically connected to the battery 13. The charging module includes a charging circuit board 14. One end of the charging circuit board 14 is electrically connected to the charging battery 13, and the other end is electrically connected to the charging port 2 located on the plug-in portion 1.
[0045] According to an embodiment of the present invention, the first half-clamping portion 15 is provided with a plurality of clamping notches, and the second half-clamping portion 16 is provided with a plurality of clamping protrusions. When the first half-clamping portion 15 and the second half-clamping portion 16 are clamped, the plurality of clamping protrusions are embedded into the corresponding clamping notches. The first half-clamping portion 15 is provided with a plurality of clamping notches, and the third half-clamping portion 17 is provided with a plurality of clamping protrusions. When the first half-clamping portion 15 and the third half-clamping portion 17 are clamped, the plurality of clamping protrusions are embedded into the corresponding clamping notches. By connecting the first half-clamping portion 15 and the second half-clamping portion 16 and the first half-clamping portion 15 and the third half-clamping portion 17 in a clamping connection manner, the assembly and disassembly of this capacitive pen are facilitated. On the one hand, it facilitates the production of the capacitive pen, and at the same time, it also facilitates the later maintenance of the capacitive pen.
