Description

Technical Field

[0001] This invention relates to the field of electronic pen technology, and in particular to an electronic pen capable of storing spare refills and its operating method. Background Technology

[0002] An electronic pen is an electronic device used with a graphics tablet or drawing tablet. When a user holds the pen and interacts with the tablet, the pen tip directly contacts the tablet, recording the strokes and thus inputting a signal. Because the pen tip frequently contacts and rubs against the tablet surface, it inevitably wears down over time. A worn-out tip doesn't make smooth contact with the surface, causing problems for users who need high-precision input. Therefore, most electronic pens on the market use a detachable pen tip structure. Once the worn tip affects normal operation, the user can remove it and replace it with a new one.

[0003] However, using replaceable refills brings new problems. The tip of the refill is crucial for the smooth operation of an electronic pen, and spare refills should be properly stored. On the other hand, refills are generally small, making them easy for users to lose. Furthermore, creating additional containers for storing spare refills would undoubtedly increase production costs, and there's no guarantee that the containers themselves won't be lost as well.

[0004] Therefore, how to properly store spare refills and reduce the chances of users accidentally discarding them is one of the technical problems that electronic pens with detachable refill structures need to solve. Summary of the Invention

[0005] The present invention aims to at least solve one of the aforementioned technical problems existing in the prior art. To this end, this application proposes an electronic pen capable of storing spare refills, which can properly preserve spare refills and reduce the risk of them being discarded.

[0006] This application also proposes a method of operating the aforementioned electronic pen capable of storing spare refills.

[0007] An electronic pen capable of storing spare refills according to a first aspect embodiment of this application includes: Pen holder; A pressing mechanism is installed in the pen holder. The pressing mechanism is capable of sliding in a first direction and rotating in the circumferential direction of the pen holder. The pressing mechanism is provided with a protrusion. A pen refill storage structure connected to the pressing mechanism, the pen refill storage structure being used to install spare pen refills; A pushing mechanism that contacts the pressing mechanism and applies a force to the pressing mechanism to push the pen holder out; A sleeve is fixedly installed in the pen holder. A limiting groove is formed inside the sleeve, and the protrusion can slide in the limiting groove. The limiting groove includes a first groove segment, a second groove segment, and a third groove segment connected at both ends to the first groove segment and the second groove segment along a first direction. The first groove segment is not connected to the end of the sleeve, and the second groove segment is connected to the end of the sleeve.

[0008] The electronic pen capable of storing spare refills according to the embodiments of this application has at least the following beneficial effects: after the spare refill is fixed in the pen holder by the refill storage structure, the spare refill can be stored in the electronic pen without the need for a separate container, thereby reducing the risk of losing the spare refill.

[0009] According to some embodiments of this application, the pen refill storage structure is provided with at least two mounting holes for fixing the spare pen refill, and the mounting holes are distributed in a circular array around the central axis of the pen refill storage structure.

[0010] According to some embodiments of this application, the pressing mechanism is provided with a push rod that extends out of the refill storage structure and contacts the pushing mechanism.

[0011] According to some embodiments of this application, the space between the push rod, the push mechanism, and the sleeve forms a space for accommodating the spare pen refill.

[0012] According to some embodiments of this application, the pushing mechanism includes an elastic element and a pushing block. The two ends of the elastic element are respectively connected to the sleeve and the pushing block. The pushing block abuts against the pushing rod under the elastic force of the elastic element.

[0013] According to some embodiments of this application, one end of the push rod is in contact with the push mechanism, and the other end of the push rod extends outward from the pressing mechanism and is bent to form a pen clip structure.

[0014] According to some embodiments of this application, the pressing mechanism is cylindrical, and the protrusion is disposed on the outer wall of the pressing mechanism; the sleeve is cylindrical and sleeved on the outside of the pressing mechanism, and the limiting groove is formed on the inner wall of the sleeve.

[0015] According to some embodiments of this application, the third groove extends along the circumferential direction of the pen holder.

[0016] According to some embodiments of this application, the third groove segment is located at one end of the first groove segment near the pushing mechanism.

[0017] The working method according to the second aspect of this application includes the following steps: In the initial state, the pressing mechanism is located inside the pen holder, the protrusion is located in the first groove, and the pushing mechanism acts on the pressing mechanism so that the protrusion abuts against the inner wall of the first groove. When the spare pen refill needs to be replaced, external pressure is applied to the pressing mechanism, the pushing mechanism is compressed, and the protrusion moves along the first groove and moves to the junction of the first groove and the third groove. Rotate the pressing mechanism so that the protrusion enters the third groove until it moves to the junction of the third groove and the second groove; Release the external pressure acting on the pressing mechanism, the pressing mechanism is pushed out of the pen holder by the pushing mechanism or external pulling force, and the protrusion moves along the second groove until it slides out of the second groove; Remove the spare pen refill from the pen refill storage structure and replace the pen refill in the electronic pen; Reinstall the pressing mechanism back into the pen holder in the reverse order of the above steps, and the replacement of the spare pen refill is complete.

[0018] The working method according to the embodiments of this application has at least the following beneficial effects: by cooperating with the limiting groove in the sleeve and the protrusion of the pressing mechanism, the disassembly and assembly of the pen refill storage structure can be easily completed, and the spare pen refill can be taken out from it. The structure is simple and effective.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0028] An electronic pen is an electronic device used with a graphics tablet or drawing tablet. When a user holds the pen and interacts with the tablet, the pen tip directly contacts the tablet, recording the strokes and thus inputting a signal. Because the pen tip frequently contacts and rubs against the tablet surface, it inevitably wears down over time. A worn-out tip doesn't make smooth contact with the surface, causing problems for users who need high-precision input. Therefore, most electronic pens on the market use a detachable pen tip structure. Once the worn tip affects normal operation, the user can remove it and replace it with a new one.

[0029] However, using replaceable refills brings new problems. The tip of the refill is crucial for the smooth operation of an electronic pen, and spare refills should be properly stored. On the other hand, refills are generally small, making them easy for users to lose. Furthermore, creating additional containers for storing spare refills would undoubtedly increase production costs, and there's no guarantee that the containers themselves won't be lost as well.

[0030] Therefore, how to properly store spare refills and reduce the chances of users accidentally discarding them is one of the technical problems that electronic pens with detachable refill structures need to solve.

[0031] In response, this application proposes an electronic pen capable of storing spare refills. The spare refills are fixed in place by a refill storage structure and stored inside the pen holder, thereby storing the spare refills in the electronic pen without the need for a separate container and reducing the risk of losing the spare refills.

[0032] In addition, this application also proposes a working method for the above-mentioned electronic pen capable of storing spare refills. By cooperating with the limiting groove in the sleeve and the protrusion of the pressing mechanism, the refill storage structure can be easily disassembled and assembled, and the spare refill can be taken out. The structure is simple and effective.

[0033] Reference Figure 1The electronic pen capable of storing spare refills according to the first aspect of this application includes a pen barrel 100, a pressing mechanism 200, a refill storage structure 300, a pushing mechanism 400, and a sleeve 500. The pen barrel 100 is the main structure of the electronic pen capable of storing spare refills and is held by the user for writing. The pressing mechanism 200 is movably mounted at one end of the pen barrel 100, and the refill storage structure 300 is fixedly connected to the pressing mechanism 200 and can move with it. A plurality of spare refills 600 are detachably mounted on the refill storage structure 300. The pushing mechanism 400 applies a force to the pressing mechanism 200, causing the pressing mechanism 200 to tend to be pushed out of the pen barrel 100. The sleeve 500 is provided with a limiting groove to limit the pressing mechanism 200.

[0034] Specifically, the pressing mechanism 200 is inserted into the pen holder 100, and the pressing mechanism 200 can move along the first direction (refer to...). Figure 1 It can slide in the x-direction and rotate in the circumferential direction of the pen holder 100, wherein the first direction is the same as the axial direction of the pen holder 100. It is worth noting that, referring to Figure 2 The pressing mechanism 200 is provided with a protrusion 210 for cooperating with the sleeve 500.

[0035] The refill storage structure 300 is connected to the pressing mechanism 200, and the refill storage structure 300 is used to install spare refills 600. The pushing mechanism 400 contacts the pressing mechanism 200 and applies a force to push the pen holder 100 out of the pressing mechanism 200. A sleeve 500 is fixedly installed in the pen holder 100, and a limiting groove is formed inside the sleeve 500. The protrusion 210 can slide in the limiting groove, thereby limiting the pressing mechanism 200. (Refer to 3 and...) Figure 4 The limiting groove includes a first groove segment 510, a second groove segment 520 formed along a first direction, and a third groove segment 530 connected at both ends to the first groove segment 510 and the second groove segment 520. The protrusion 210 can slide back and forth between the first groove segment 510, the second groove segment 520, and the third groove segment 530. It is worth noting that the first groove segment 510 is not in contact with the end of the sleeve 500, so the protrusion 210 cannot disengage from the limiting groove from the end of the sleeve 500 along the first groove segment 510; the second groove segment 520 is in contact with the end of the sleeve 500, so the protrusion 210 can disengage from the limiting groove from the end of the sleeve 500 along the second groove segment 520.

[0036] The working principle of the electronic pen capable of storing spare refills is as follows: During normal use, the protrusion 210 is located in the first slot 510, and due to the action of the pushing mechanism 400, the pressing mechanism 200 tends to push outwards, causing the protrusion 210 to abut against the end of the first slot 510. When a refill needs to be replaced, an external force is applied to the pressing mechanism 200, causing the protrusion 210 to slide to the junction of the first slot 510 and the third slot 530. Then, the pressing mechanism 200 is rotated, causing the protrusion 210 to slide to the junction of the third slot 530 and the second slot 520. At this point, the external force is released, and the protrusion 210 can slide out of the second slot 520 under the action of the pushing mechanism 400 or an external pulling force. The pressing mechanism 200 is then removed from the pen holder 100. The user can then remove the spare refill 600 from the refill storage structure 300 to complete the subsequent refill replacement.

[0037] Furthermore, the pen refill storage structure 300 is provided with at least two mounting holes 310. The mounting holes 310 are used to fix the spare pen refills 600. The mounting holes 310 are arranged in a circular array around the central axis of the pen refill storage structure 300, so that each spare pen refill 600 is evenly inserted on the pen refill storage structure 300, keeping the center of gravity of the entire electronic pen on its central axis. As for the specific number of mounting holes 310, it can be increased or decreased according to the actual situation, which will not be elaborated here.

[0038] Furthermore, the pressing mechanism 200 is provided with a push rod 220, which extends from the refill storage structure 300 and contacts the pushing mechanism 400. On the one hand, the push rod 220 serves as a force transmission component to transmit the force between the pushing mechanism 400 and the pressing mechanism 200; on the other hand, the space between the push rod 220, the pushing mechanism 400, and the sleeve 500 forms a space for accommodating the spare refill 600, thereby preventing the pushing mechanism 400 from directly applying force to the spare refill 600 and damaging it.

[0039] Furthermore, the jacking mechanism 400 includes an elastic element 410 and a jacking block 420. The two ends of the elastic element 410 are connected to the sleeve 500 and the jacking block 420, respectively. The jacking block 420 abuts against the jacking rod 220 under the elastic force of the elastic element 410. The elastic element 410 can be a spring, a pneumatic telescopic tube, or an elastic element made of elastic materials such as silicone, thereby applying a force to the jacking block 420.

[0040] Furthermore, one end of the push rod 220 contacts the push mechanism 400, and the other end of the push rod 220 extends outward from the pressing mechanism 200 and bends to form a pen clip structure. On the one hand, the outwardly bent push rod 220 facilitates the user to apply force to drive the pressing mechanism 200 to rotate; on the other hand, the pen clip structure allows the electronic pen to be clipped and fixed to clothing, a writing tablet, a drawing tablet, or other components, thereby giving the electronic pen a fixed function.

[0041] Furthermore, the pressing mechanism 200 is cylindrical, and the protrusion 210 is disposed on the outer wall of the pressing mechanism 200. The sleeve 500 is cylindrical and is fitted onto the outer side of the pressing mechanism 200, and a limiting groove is formed on the inner wall of the sleeve 500. Thus, after the sleeve 500 is fitted onto the outer side of the pressing mechanism 200, the protrusion 210 can slide into the limiting groove, completing the engagement between the pressing mechanism 200 and the sleeve 500. Moreover, since both the pressing mechanism 200 and the sleeve 500 are cylindrical, the rotation of the pressing mechanism 200 is not affected, and it can rotate smoothly to allow the protrusion 210 to slide in the third groove section 530 of the limiting groove.

[0042] Furthermore, the third groove 530 extends along the circumferential direction of the pen holder 100, so that the protrusion 210 can move in the third groove 530 when the pressing mechanism 200 rotates.

[0043] Furthermore, the third groove segment 530 is located at the end of the first groove segment 510 closest to the push mechanism 400. Thus, during normal use of the electronic pen, the push mechanism 400 drives the protrusion 210 of the pressing mechanism 200 to abut against the end of the first groove segment 510 furthest from the third groove segment 530, thereby limiting the position of the protrusion 210.

[0044] The working method in the second aspect embodiment of this application, which is applied to the above-mentioned electronic pen capable of storing spare refills, includes the following steps: S100. In the initial state, refer to Figure 1 The pressing mechanism 200 is located inside the pen holder 100, the protrusion 210 is located in the first groove 510, and the pushing mechanism 400 acts on the pressing mechanism 200 so that the protrusion 210 abuts against the inner wall of the first groove 510, thereby limiting the position of the protrusion 210. S200. When a spare 600 refill needs to be replaced, refer to... Figure 5 External pressure acts on the pressing mechanism 200, the pushing mechanism 400 is compressed, and the protrusion moves along the first groove section 510 and moves to the junction of the first groove section 510 and the third groove section 530. S300. Rotate the pressing mechanism 200 so that the protrusion 210 enters the third groove 530 until it moves to the junction of the third groove 530 and the second groove 520; S400. Reference Figure 6The external pressure acting on the pressing mechanism 200 is released, and the pressing mechanism 200 is pushed out of the pen holder 100 by the pushing mechanism 400 or the external pulling force. The protrusion 210 moves along the second groove section 520 until it slides out of the second groove section 520. S500. Remove the spare pen refill 600 from the pen refill storage structure 300 and replace the pen refill of the electronic pen; S600. Reinstall the pressing mechanism 200 back into the pen holder 100 in the reverse order of the above steps. The replacement of the spare pen refill 600 is now complete.

[0045] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
