The application provides an intelligent pen.

Referring to fig. 1 and 2 in combination, in an embodiment of the present application, the smart pen includes a barrel 10, a pen core 30, and a guide structure 50. Wherein the pen holder 10 is provided with a touch switch 11; the pen core 30 is movably arranged on the pen holder 10, the pen core 30 can move relative to the pen holder 10 to be in contact with the touch switch 11, and the length of the pen core 30 is not less than 70 mm and not more than 150 mm; the guide structure 50 is provided to the barrel 10 to guide the movement of the cartridge 30.

In an embodiment of the present application, the pen holder 10 is mainly used for mounting and carrying the pen core 30, the guide structure 50, etc., and its projection on the horizontal plane may be a circular structure so as to facilitate the user to hold the pen core. In order to prolong the service life of the pen holder 10, the pen holder 10 may be made of metal materials, for example: aluminum material, aluminum alloy material, copper alloy material, iron material, stainless steel material, etc.; of course, in order to reduce the weight of the pen holder 10, the pen holder 10 may be made of plastic, for example: ABS, POM, PS, PMMA, PC, PET, etc. The touch switch 11 is mainly used for sensing the working state of the smart pen so as to trigger the camera electrically connected with the touch switch 11 on the smart pen to work. Specifically, when the smart pen is writing or drawing, that is, in an operating state, the pen core 30 is moved by the pressing pressure of the display screen, the touch screen, or the paper, and is in an operating state. At this time, the pen core 30 abuts against the touch switch 11 and triggers the touch switch 11 to work, so that the camera can be started to perform normal capturing work on the input information after acquiring the trigger signal. The pen core 30 is mainly used for writing or drawing on a display screen, a touch screen or paper, wherein the pen core 30 can be a plastic pen core 30 when the pen core is used for writing or drawing on the display screen or the touch screen; when writing or drawing on the cardboard, the pen core 30 may be a carbon-free pen core 30 or a whiteboard ink pen core 30, which is not limited in the application, and the smart pen can write or draw on a display screen and/or a touch screen and/or paper. The guiding structure 50 is mainly used for guiding the movement of the pen core 30, and ensures the stability of the pen core in the moving process.

When the intelligent pen of the technical scheme of the application writes or draws on the display screen, the touch screen or the paper, the pen core 30 is movably arranged on the pen holder 10, so that the pen core 30 moves under the extrusion pressure of the display screen, the touch screen or the paper. After the pen core 30 moves a certain distance, the pen core can be abutted against the touch switch 11, so that a camera electrically connected with the touch switch 11 on the intelligent pen is started, and the intelligent pen can acquire the input information of the intelligent pen on a display screen, a touch screen or paper. Because the intelligent pen in the scheme is further provided with the guide structure 50 on the pen holder 10, the movement of the pen core 30 can be guided through the guide structure 50. So avoided refill 30 to take place the skew at the removal in-process for refill 30 is comparatively steady and can be accurate in the removal in-process to touch contact switch 11, thereby improved refill 30 and touch switch 11 contact evenly, stability, guaranteed the normal work of intelligent pen. In addition, the length of the pen core 30 is not less than 70 mm, so that the influence on the capacity of ink in the pen core 30 caused by the too small length of the pen core 30 is avoided; and the length of the pen core 30 is not more than 150 mm, the influence on the stability of the pen core 30 in the writing moving process due to the overlarge length of the pen core 30 is avoided. Further, the length of the pen refill 30 is longer than that of the pen refill 30 of the intelligent pen in the prior art, so that more ink can be contained to facilitate durable writing, the number of times of replacing the pen refill 30 is reduced, and the use convenience of the intelligent pen can be improved. Moreover, the length of this type of cartridge 30 is used more in the non-smart pen market, for example: the center cartridge can thus make the cartridge 30 easy to purchase for replacement, thereby further improving the convenience of use of the smart pen. Further, the diameter of the cartridge 30 may be set to not less than 2 mm and not more than 6 mm.

Referring to fig. 2, in an embodiment of the present application, the guiding structure 50 includes a guiding cavity 50a, wherein the guiding cavity 50a is disposed in the pen holder 10 and extends along the moving direction of the pen core 30; the pen core 30 comprises a pen core body 31 and a pen point 33 connected to the pen core body 31, the pen core body 31 is at least partially movably embedded in the guide cavity 50a, one end, far away from the pen point 33, of the pen core body 31 can be abutted against the touch switch 11, and the pen point 33 is exposed to the outside through the guide cavity 50 a.

In addition, the pen core body 31 is at least partially embedded in the guide cavity 50a, so that the pen core 30 and the pen holder 10 can be distributed more compactly, and the whole volume of the intelligent pen is reduced, so that the intelligent pen is convenient for a user to hold. Meanwhile, the protection cavity also has a certain protection effect on the pen core body 31, so that most of the pen core body is prevented from being damaged easily due to the fact that the pen core body is exposed outside. Further, in order to prevent the nib 33 from being damaged by being easily collided with foreign objects, the smart pen may further include a cap provided at the outside of the barrel 10, and the nib 33 is received in the cap. When the intelligent pen needs to write or draw, the pen cap is pulled out from the pen holder 10, so that the pen point 33 is exposed to the outside; when the intelligent pen needs to be stored, the pen cap is sleeved on the pen holder 10, so that the pen point 33 can be accommodated in the pen cap. The pen cap and the pen holder 10 may be fastened and fixed, specifically, the pen in the pen cap is provided with a buckle, the outer wall of the pen holder 10 is provided with a clamping groove, and the buckle is clamped into the clamping groove, so that the pen cap is fixed on the pen holder 10.

Meanwhile, the guide sleeve 51 is arranged, so that the influence on the service life of the pen holder 10 caused by direct abrasion of the pen core 30 and the cavity wall of the guide cavity 50a in the moving process is avoided, and the guide sleeve 51 is more convenient to manufacture relative to the pen holder 10, so that the complexity of maintenance or replacement of the intelligent pen due to abrasion is reduced. Further, in order to reduce the abrasion of the pen core 30 caused by the movement process to the guide sleeve, the guide sleeve 51 may be made of a material with better abrasion resistance, such as steel or alloy.

In one embodiment of the present application, the guide sleeve 51 abuts against the wall of the guide cavity 50a, and the pen holder 10 and the pen core 30 cooperate to clamp and fix the guide sleeve 51.

It can be appreciated that the fixing structure of the guide sleeve 51 is simplified by clamping the pen holder 10 and the pen core 30 to fix the guide sleeve 51, thereby reducing the manufacturing cost of the smart pen and improving the assembly efficiency of the smart pen. Wherein, the pen holder 10 may be provided with an opening at an end surface thereof so that the guide bush 51 is inserted into the guide cavity 50a from the end surface opening; of course, the side circumferential surface may be provided with an opening so that the guide bush 51 is fitted into the guide chamber 50a from the side circumferential surface opening, which is not limited to this aspect of the application.

In one embodiment of the present application, the guide bush 51 is provided with one of a rotation stop block and a rotation stop groove, and the cavity wall of the guide cavity 50a is provided with one of a rotation stop block and a rotation stop groove, into which the rotation stop block is inserted.

In an embodiment of the present application, the guide bush 51 is provided in an annular integrated structure or in a split structure of a plurality of pieces spliced in the circumferential direction of the guide bush 51.

It can be understood that the guide sleeve 51 is arranged in an annular integrated structure so as to facilitate the forming of the guide sleeve 51, thereby improving the production efficiency of the guide sleeve 51; and at the same time, the installation of the guide sleeve 51 is facilitated, so that the assembly efficiency of the intelligent pen can be improved. When the guide sleeve 51 is in a split structure formed by splicing a plurality of pieces, the spliced body can be maintained and replaced when the part of the guide sleeve 51 is damaged, so that the whole guide sleeve 51 is prevented from being maintained and replaced due to the local damage, and the maintenance and replacement cost of the guide sleeve 51 is reduced. Meanwhile, a plurality of splice bodies can be distributed at intervals to form the guide sleeve 51, so that the use of production materials is reduced, and the manufacturing cost of the guide sleeve 51 is reduced.

Referring to fig. 2 and 3 in combination, in an embodiment of the application, the touch switch 11 has a touch end 111, the touch end 111 is embedded in the guiding cavity 50a, and an end of the pen core body 31 away from the pen tip 33 can be abutted against the touch end 111.

It can be understood that the touch end 111 is embedded in the guiding cavity 50a, so that one end of the pen core body 31, which contacts with the touch end 111, is always located in the guiding cavity 50a during moving, so that the pen core body 31 and the touch switch 11 are still guided by the guiding assembly during touch triggering, and the stability of the contact between the pen core body 31 and the touch switch 11 is further improved. Meanwhile, the contact end 111 is embedded in the guide cavity 50a, so that the contact end is prevented from being damaged easily due to the fact that the contact end is exposed outside, and the service life of the touch switch 11 is prolonged.

In an embodiment of the present application, the touching end 111 is at least partially inserted into the guide sleeve 51 and abuts against the inner surface of the guide sleeve 51.
