Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic pens, and particularly relates to an electronic pen and a touch device. Background Art
[0002] Electronic pens are used for electronic devices such as smart phones and tablet computers. When through holes are formed in the pen body of an electronic pen, electrostatic tests need to be performed on the positions of the through holes to ensure that the electronic pen meets the test requirements for contact static electricity and air static electricity. Contact static electricity refers to static charges generated when two objects come into contact or rub against each other, while air static electricity refers to an object carrying static charges in the air.
[0003] In related technologies, for electrostatic tests with low requirements, the anti-static performance of the circuit board itself in the electronic pen can meet the corresponding requirements. For electrostatic tests with high requirements, the voltage level of the contact static electricity test reaches 8 kilovolts (kV). When static charges accumulate on the surface of the circuit board and suddenly discharge, a high-voltage instantaneous current will pass through the circuit board, which may cause the circuit board to be damaged. That is, the anti-static performance of existing electronic pens is poor. Summary of the Utility Model

Moreover, the pen casing 100 is also provided with a first through hole 120, and the first through hole 120 communicates with the accommodation cavity 110. In some embodiments, the first through hole 120 can be used to install components such as the button 500, the lamp body or the speaker. In other embodiments, the first through hole 120 can also be used as a ventilation hole or a sound hole, etc. The specific setting of the first through hole 120 can be determined according to the actual situation. It should be noted that, in some embodiments, the first through hole 120 can be provided on the peripheral wall of the pen casing 100. In other embodiments, the first through hole 120 can also be provided on the end wall of the pen casing 100. Some embodiments of the present application will take the first through hole 120 being provided on the peripheral wall of the pen casing 100 as an example for illustration.

The conductive part 300 includes a first conductive end 311 and a second conductive end 321, and the first conductive end 311 is electrically connected to the second conductive end 321. In some embodiments, the conductive part 300 can be a single conductive piece, that is, the first conductive end 311 and the second conductive end 321 are respectively two ends of the same conductive piece. In other embodiments, the conductive part 300 includes two conductive pieces. The first conductive end 311 can be any end of one of the conductive pieces, and the second conductive end 321 can be any end of the other conductive piece.

The pen housing 100 includes an internal accommodating cavity 110 and a first through hole 120 communicating with the accommodating cavity 110, and the circuit board 200 is arranged in the accommodating cavity 110. In the prior art, when the through hole position of the electronic pen is subjected to an electrostatic test, a high voltage instantaneous current will directly pass through the circuit board, which may easily cause the circuit board and the electronic components located thereon to be damaged or injured. The electronic pen 10 of the present solution has a conductive part 300, and the conductive part 300 includes a first conductive end 311 and a second conductive end 321 electrically connected to each other. The first conductive end 311 is arranged around the hole axis 121 of the first through hole 120, and the second conductive end 321 is electrically connected to the grounding structure 210 of the circuit board 200. That is, when an electrostatic test is performed on the position of the first through hole 120 of the electronic pen 10, static electricity can be introduced into the grounding structure 210 of the circuit board 200 through the first conductive end 311 and the second conductive end 321 to achieve grounding, thereby preventing the circuit board 200 from being damaged, and effectively improving the anti-static performance of the electronic pen 10.

In some embodiments, the first conductive end 311 can be arranged around the hole axis 121 of the first through hole 120, that is, it can effectively absorb static electricity at various positions along the circumference of the first through hole 120, thereby ensuring the anti-static performance of the electronic pen 10. In other embodiments, the first conductive end 311 can also be arranged around part of the circumference of the first through hole 120 at a small angle, and the specific arrangement of the first conductive end 311 can be determined according to actual conditions.

In some embodiments, the pen housing 100 has an inner peripheral wall 111 facing the accommodating cavity 110, the first conductive end 311 fits the inner peripheral wall 111 of the pen housing 100, and the first conductive end 311 is arranged around the inner opening 122 of the first through hole 120, that is, the first conductive end 311 in this solution can be sufficiently close to the first through hole 120, which can effectively improve the electrostatic absorption effect of the conductive part 300 at the position of the first through hole 120, and ensure the anti-static performance of the electronic pen 10.
[0050] In some other embodiments, the electronic pen 10 further includes a bracket 400, and the bracket 400 can penetrate through the accommodation cavity 110. The first conductive end 311 of the conductive portion 300 can be connected to the bracket 400, and the first conductive end 311 can be arranged at an interval from the inner peripheral wall 111 of the pen housing 100. In other embodiments, the first through hole 120 has an inner hole wall 123 inside it, the first conductive end 311 can be attached to the inner hole wall 123 of the first through hole 120, and is arranged to extend along the circumferential direction of the inner hole wall 123. The first conductive end 311 of this solution can also fully approach the first through hole 120, which can effectively improve the electrostatic absorption effect of the conductive portion 300 at the position of the first through hole 120.

The circuit board 200 can be connected to the bracket 400. And, there is a gap 124 between the pen housing 100 and the bracket 400, and the first conductive member 310 can be arranged in this gap 124. Both sides of the first conductive end 311 can be respectively connected to the pen housing 100 and the bracket 400. In other words, the pen housing 100 and the bracket 400 can jointly clamp the first conductive end 311. This solution can effectively improve the stability of the assembly connection of the conductive portion 300, and further ensure the anti-static stability of the electronic pen 10.

The specific setting position of the groove 420 can be determined according to the actual situation. Some embodiments of this application take the groove 420 being arranged on the bracket 400 as an example for illustration. The groove 420 in this solution can prevent the first conductive end 311 from moving around in the pen housing 100, and ensure the stability of the assembly connection of the first conductive end 311.

Further, the intervals between two adjacent protrusions 430 may be uniform intervals or non-uniform intervals. In some embodiments of the present application, the case where the intervals between two adjacent protrusions 430 are non-uniform intervals is taken as an example for illustration. It should be noted that the protrusions 430 may be arranged in contact with the first through hole 120. A plurality of notches 312 may be provided at the first conductive end 311 of the conductive part 300, and each of the protrusions 430 may pass through each of the notches 312 one by one. That is, the protrusions 430 can effectively position the first conductive end 311, and the notches 312 at the first conductive end 311 can be effectively connected to the static electricity test, improving the reliability of anti-static.

Since the circuit board 200 is disposed between the first frame 440 and the second frame 450, this solution can achieve pre-assembly between the first conductive member 310, the bracket 400, and the circuit board 200, improve the assembly efficiency, and ensure the stability of the assembly connection between the components.
