Wherein, be equipped with holding chamber 12 in the pen shell 1, the chamber bottom of holding chamber 12 is sealed and towards the nib end of pen shell 1, and the chamber outer wall of holding chamber 12 and pen shell 1 form spout 13. The camera device 3 and the control circuit board 4 are installed in the accommodating cavity 12, the control circuit board 4 is in communication connection with the camera device 3, and the magnetic induction element 41 is installed on the control circuit board 4. The pressing head 2 is slidably mounted on the pen shell 1, the pressing head 2 is provided with a pin 211, the pin 211 is slidably inserted into the sliding groove 13, and the pin 211 is provided with a magnet 6. The magnetic induction element 41 is used for controlling the image pickup device 3 to be turned on or off according to the magnetic field intensity change of the magnet 6.

The accommodating cavity 12 is a cavity extending along the length direction of the pen shell 1, one side of the accommodating cavity 12 facing the pen tip of the pen shell 1 is a bottom side, and at least the cavity bottom of the accommodating cavity 12 is connected with the cavity wall in a closed manner to form a closed end. For example, in one embodiment, the receiving cavity 12 is a separate housing member with a closed bottom end, the housing member is fixedly installed inside the pen case 1, the bottom end of the housing member faces the pen tip end of the pen case 1, and a gap is left between the housing wall of the housing member and the inner wall of the pen case 1, and the gap forms a sliding slot 13 extending along the length direction of the pen case 1. In another embodiment, a cavity bottom plate perpendicular to the inner wall is connected to the inner wall of the pen case 1, a gap is left between a part of the edge of the cavity bottom plate and the inner wall of the pen case 1, the part of the edge is fixedly connected to a cavity wall plate extending along the length direction of the pen case 1, and the cavity wall plate is also fixedly connected to the inner wall of the pen case 1. Therefore, the cavity bottom plate, the cavity wall plate and part of the inner wall of the pen shell 1 jointly form the accommodating cavity 12, and the cavity wall plate and the inner wall of the pen shell 1 outside the accommodating cavity 12 form a sliding groove 13 extending along the length direction of the pen shell 1. It is understood that the receiving chamber 12 may be in other similar configurations, and the utility model is not limited thereto.

Electronic elements such as the camera device 3, the control circuit board 4 and the battery 5 are installed in the accommodating cavity 12, wherein the control circuit board 4 is provided with a magnetic induction element 41, the magnetic induction element 41 faces the wall of one side cavity of the accommodating cavity 12, and the wall of the side cavity and the inner wall of the pen shell 1 form a chute 13.

The pressing head 2 is arranged at the pen point end of the pen shell 1, and the pressing head 2 is positioned outside the accommodating cavity 12 and opposite to the cavity bottom of the accommodating cavity 12. The pressing head 2 is provided with a pin 211, the pin 211 is inserted into the sliding groove 13, and the magnet 6 is installed at the tail end of the pin 211, so that the magnet 6 is opposite to the magnetic induction element 41 at the interval of the cavity wall of the accommodating cavity 12. When the pressing head 2 is pressed, the pins 211 slide in the sliding groove 13 along the length direction of the pen shell 1. Along with the sliding of the pin 211, the magnet 6 approaches or departs from the magnetic induction element 41, so that the magnetic induction element 41 outputs different detection signals according to different magnetic field strengths, and the imaging device 3 is correspondingly controlled to be turned on or turned off.

The electronic pen provided by the utility model has the advantages that electronic elements such as the camera device 3, the control circuit board 4, the battery 5 and the like are all arranged in the accommodating cavity 12 with the closed bottom end, and the pressing head 2 is arranged outside the accommodating cavity 12. Therefore, the pressing head 2 does not directly contact with the image pickup device 3, the control circuit board 4 and other electronic components, but the pins 211 of the pressing head 2 slide in the accommodating cavity 12 and the slide groove 13 formed by the pen shell 1 and extending along the length direction of the pen shell 1, so that the magnetic induction element 41 on the control circuit board 4 detects the change of the magnetic field intensity of the magnet 6 mounted on the pins 211 of the pressing head 2, and correspondingly outputs a control signal to control the opening and closing of the image pickup device 3, thereby achieving the effect that the image pickup device 3 starts scanning when the pressing head 2 is pressed. Because the holding chamber 12 is closed at the nib end of the pen shell 1, external dust, water mist, impurities and the like cannot enter the holding chamber 12 from the gap between the pressing head 2 and the pen shell 1 to contaminate electronic elements such as the camera device 3, the control circuit board 4 and the like, the sealing performance of the electronic pen is obviously improved, and the service life of the electronic pen can be effectively prolonged.

That is, the partition plate 11 forms a bottom of the accommodating chamber 12, and the inner wall of the housing 10 forms a wall of the accommodating chamber 12. Because the circumferential edges of the partition plates 11 are connected to the inner wall of the housing 10, the accommodating cavity 12 forms a closed structure at the cavity bottom, and external impurities cannot enter the accommodating cavity 12 from the cavity bottom.

The partition plate 11 is provided with a bent section at an edge portion thereof, and the bent section and the inner wall of the housing 10 form a slide groove 13. As shown in fig. 2, the isolation plate 11 is provided with a first bending section 131 at a gap from the inner wall of the casing 10, and the first bending section 131 extends a distance along the length of the casing 10 in a direction away from the pen tip; the end of the first bending section 131 is provided with a second bending section 132, and the second bending section 132 extends towards the inner wall of the housing 10 so that the edge of the isolation plate 11 is connected to the inner wall of the housing 10.

For example, in some embodiments, the bottom end of the accommodating cavity 12 is provided with a light hole, the light hole is opposite to the camera 3, and a light-transmitting plate is installed on the light hole. The bottom end of the cavity may be a partition plate 11 integrally formed with the housing 10, or a partition plate 11 welded to the housing 10. Wherein, the light-transmitting plate can be plates such as colorless transparent glass, colorless transparent plastics and the like. In one embodiment, the light-transmitting plate is welded to the wall of the light-transmitting hole. In another embodiment, the light-transmitting plate is embedded in the light-transmitting hole through a sealing ring. Because the light-transmitting plate and the light-transmitting hole are fixedly connected in a sealing way, the sealing performance of the accommodating cavity 12 at the bottom of the cavity can still be ensured.

In other embodiments, the bottom end of the receiving cavity 12 may be entirely made of a light-transmitting material. For example, the accommodating cavity 12 is a partition plate 11 welded to the housing 10, and the partition plate 11 is a colorless transparent glass plate or a colorless transparent plastic plate; or the accommodating cavity 12 is an independent shell member fixedly arranged in the pen shell 1, and the shell member is a colorless transparent plastic piece as a whole.
