Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The present utility model provides an intelligent pen with a magnetic suspension structure, referring to fig. 1-4, the intelligent pen comprises: refill 1, refill holder 2, penholder 3 and pen container. Wherein, the pen core clamping piece 2 adopts a square block structure, and a pair of clamping arms 20 for clamping the pen core 1 extend towards the same direction on the square block structure; one end of the pen rack 3 is provided with a chute 31 which is in sliding fit with the pen core clamping piece 2, the other end of the pen rack 3 is provided with a pen core through hole 32, and the tail end of the pen core 1 penetrates into the pen rack 3 from the pen core through hole 32 and is clamped in the pen core clamping piece 2 at the chute 31. When a new pen core 1 needs to be replaced, only the tip of the old pen core 1 needs to be pinched, the old pen core 1 is pulled out of the pen core clamping piece 2, and the tail end of the new pen core 1 passes through the pen core perforation 32 and is clamped in the pen core clamping piece 2.

The pen holder 3 is provided with a limit bar 30, the pen container is provided with a limit groove 40 which is matched with the limit bar 30, the pen holder 3, the pen core clamping piece 2 and the whole pen core 1 are sleeved in the pen container through clamping of the limit bar 30 and the limit groove 40, and the pen container end cover 42 for blocking the pen container body 41 is spliced through clamping, so that the intelligent pen is assembled. The end cap limiting bar 421 extends from one end of the pen rack 3 far away from the pen rack head, and the pen container end cap 42 is provided with an end cap limiting groove 422 matched with the end cap limiting bar.

The rear end of the cartridge holder 2 is provided with a first mounting groove 21 for fitting the first magnet 210. The pen holder 3 is provided with a second mounting groove 33 for fitting the second magnet 330 so that the position of the second magnet 330 corresponds to the position of the first magnet 210. The first magnet 210 and the second magnet 330 adopt homopolar magnets, and a repulsive force is generated between the first magnet 210 and the second magnet 330 according to the principle of homopolar repulsion, so that a magnetic suspension state is maintained between the two magnets.

Referring to fig. 5 to 6, the first mounting groove 21 has a first end surface 211 capable of conducting magnetism of the first magnet 210, and a sensing protrusion 212 is disposed on the first end surface 211; the second mounting groove 33 has a second end surface 331 corresponding to the first end surface 211, the second end surface 331 can conduct magnetism of the second magnet 330, the second end surface 331 is attached with an electronic trigger element 332, and after the sensing protrusion 212 touches the electronic trigger element 332, writing information of the pen core 1 can be conducted to the electronic trigger element 332.

Since the first magnet 210 is embedded in the pen core holder 2, the pen core holder 2 is slidably matched with the chute 31 of the pen rack 3, so that the second magnet 330 in a fixed state can give a repulsive force to the slidable first magnet 210 when the pen core 1 does not write, and the first magnet 210 drives the pen core holder 2 to slide in the chute 31, so that the pen core holder 2 is separated from the electronic trigger element 332; when writing the pen refill 1, the pen refill 1 receives pushing force from the desktop, and then the pen refill 1 pushes the pen refill clamping piece 2, so that the sensing protrusion 212 of the pen refill clamping piece 2 abuts against the electronic triggering element 332, the electronic triggering element 332 is triggered, and writing storage information of the pen refill 1 is transmitted to the electronic triggering element 332. Here, the electronic triggering element 332 may specifically be a contact switch or a pressure sensor.

In order to avoid damage caused by overlarge pressure on the electronic triggering element 332, the utility model sets a limiting step 333 on the second end surface 331 of the second mounting groove 33 for resisting the first end surface 211 of the first mounting groove 21, thereby realizing the limiting of the sensing protrusion 212 on the first end surface 211 and preventing the sensing protrusion 212 from excessively resisting the electronic triggering element 332. Specifically: when writing, the first end surface 211 of the pen core clamping piece 2 is abutted against the limiting step 333 through the limiting step 333, so that the limiting step 333 bears most of the pressure from the pen core clamping piece 2, and the pressure is prevented from being concentrated on the electronic trigger element 332, so that the pressure damage to the electronic trigger element 332 is relieved, and the service life of the electronic trigger element is prolonged. Still further, the method comprises the steps of: when the pen core head of the pen core 1 of the intelligent pen falls to the ground, the pen core 1 receives a larger impact force, and if the limit step 333 bears the impact force of the part, the pen core clamping member 2 may seriously damage the electronic trigger element 332, so that the related functions of the intelligent pen cannot be normally used.

It should be noted that, in the present utility model, the length of the limiting step 333 is slightly smaller than the length of the sensing protrusion 212, so that the following two points are satisfied: firstly, the electronic triggering element 332 is prevented from being damaged due to excessive compression; secondly, after the limiting step 333 is set, the sensing protrusion 212 can still touch the electronic triggering element 332, so that the electronic triggering element 332 is triggered.

In order to further mitigate the pressure damage to the electronic triggering element 332, the sensing protrusion 212 of the present utility model adopts a hemispherical structure.

The beneficial effects of the utility model are as follows:

(1) The limiting step 333 is arranged, the length of the limiting step 333 is slightly smaller than that of the sensing protrusion 212, when writing pressure drives the pen core clamping piece 2 to slide towards the electronic trigger element 332, the first end surface 211 of the pen core clamping piece 2 is firstly abutted against the limiting step 333, and is not directly acted on the electronic trigger element 332 by the sensing protrusion 212, so that the situation that the pressure is fully concentrated on the electronic trigger element 332 and the electronic trigger element 332 is damaged due to exceeding the stress range of the electronic trigger element 332 is effectively avoided;

(2) The provision of the sensing protrusion 212 in a hemispherical configuration further reduces pressure damage to the electronic triggering element 332.

The foregoing description of the preferred embodiment of the utility model is not intended to limit the utility model to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
