[0002] At present, in order to ensure the fineness of input operations such as writing or drawing on a touch panel with a capacitive touch input function, a capacitive pen must be used.

[0003] After long-term use, the refill of the existing capacitive pen is easily damaged. Therefore, the refill of the capacitive pen needs to be replaced regularly. In the prior art, the connection between the refill of the capacitive pen and the capacitive pen is mostly that the refill is inserted into the inside of the capacitive pen from one end of the capacitive pen and then matched with the threaded part inside the capacitive pen. When replacing the refill, the original refill needs to be rotated and removed from one end of the capacitive pen, and then the new refill is inserted into the inside of the capacitive pen and screwed with the threaded part. Although this refill connection method is relatively firm, it is difficult to quickly align the refill with the threaded part of the capacitive pen when replacing the refill, which makes the refill replacement process more cumbersome and inconvenient, making the refill replacement efficiency relatively low.

DETAILED DESCRIPTION

[0034] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] See also Figure 1 The present embodiment provides a capacitive pen with replaceable conductive pen core, comprising a pen housing 10, a receiving assembly 20, an arc plate 60, a limiting assembly 70 and a pushing assembly 80, wherein the arc plate 60 is fixedly arranged on the inner wall of the pen housing 10, and a plurality of pen cores distributed in sequence are stored between the arc plate 60 and the inner wall of the pen 10, the limiting assembly 70 is movably arranged at one end of the arc plate 60, and is used to limit a plurality of the pen cores between the arc plate 60 and the pen housing 10, and one end of the pushing assembly 80 is in contact with the pen cores. The receiving assembly 20 is connected to the inner wall of the pen shell 10, and the other end extends to between the arc plate 60 and the pen shell 10. One end of the receiving assembly 20 extends to the inside of the pen shell 10, and the other end extends to the outside of the pen shell 10. When the receiving assembly 20 moves, it can drive the limiting assembly 70 to move to release the limitation on several of the pen cores. The pushing assembly 80 pushes several of the pen cores between the arc plate 60 and the pen shell 10 to drive a group of the pen cores at the edge to fall to the inside of the receiving assembly 20.

[0037] When the refill of the capacitive stylus pen needs to be replaced, the receiving component 20 moves, thereby driving the limiting component 70 to move, so that the limiting component 70 is removed from one end of the arc plate 60 to release the restriction on several refills between the arc plate 60 and the pen shell 10. At this time, the pushing component 80 pushes several refills, so that a group of refills at the edge falls to the inside of the receiving component 20, completing the automatic replacement of the refills.

[0038] See also Figure 1 and Figure 3 In one embodiment, the limiting assembly 70 includes a ring sleeve 702 and a baffle 701 fixedly arranged on the side wall of the ring sleeve 702, and the end of the baffle 701 away from the ring sleeve 702 extends to one side of the arc plate 60, and the pushing assembly 80 includes a pushing block 801 and a second elastic member 802. A second supporting block 104 is fixedly arranged on the inner wall of the pen shell 10, and the pushing block 801 is movably arranged between the arc plate 60 and the pen shell 10. One end of the second elastic member 802 is connected to the pushing block 801, and the other end is connected to the second supporting block 104, which is used to provide elastic support for the pushing block 801.

[0039] Initially, the baffle 701 extends to one end of the arc plate 60 to block and limit a number of pen refills between the arc plate 60 and the pen case 10. When the pen refills need to be replaced, the receiving assembly 20 moves, thereby driving the ring sleeve 702 and the baffle 701 to move, so that the baffle 701 is removed from one end of the arc plate 60 to release the restriction on the pen refills. At this time, the push block 801 is driven to move between the arc plate 60 and the pen case 10 through the support of the second elastic member 802, thereby pushing the pen refills, so that the outermost group of pen refills are removed from the inner side of the arc plate 60, and the receiving assembly 20 is used to receive the removed pen refills to complete the automatic replacement of the pen refills.

[0040] See also Figure 1 and Figure 2 In one embodiment, a slide groove 101 is provided on the side wall of the pen housing 10 along the length direction, and the receiving assembly 20 includes a U-shaped receiving plate 204, and a sensor 30, a pen control chip 40 and a battery 50 are fixedly arranged in sequence inside the U-shaped receiving plate 204, a second connecting rod 203 is fixedly arranged at one end of the U-shaped receiving plate 204, and an extension block 205 is fixedly arranged on the side wall of the U-shaped receiving plate 204, and the end of the second connecting rod 203 away from the U-shaped receiving plate 204 passes through the ring sleeve 702 and is fixedly provided with the first connecting rod 202, and the end of the first connecting rod 202 away from the second connecting rod 204 extends from the slide groove 101 to the outside of the pen housing 10 and is connected with a paddle 201.

[0041] When the pen core needs to be replaced, the paddle 201 can be pushed. The paddle 201 drives the second connecting rod 203 and the U-shaped receiving plate 204 to move inside the pen housing 10 through the first connecting rod 202. When the U-shaped receiving plate 204 moves, the extension block 205 of its side wall acts on the edge of the ring sleeve 702, thereby pushing the baffle 701 to move, so that the baffle 701 is removed from one end of the arc plate 60 to release the restriction on several pen cores. At this time, the second elastic member 802 pushes the push block 801 to move, and the push block 801 pushes several pen cores so that a group of pen cores at the edge are removed from one end of the arc plate 60 and fall to the inside of the U-shaped receiving plate 204. When the pen core falls to the inside of the U-shaped receiving plate 204, one end of the pen core contacts the sensor 30, so that the pen core, the sensor 30 and the pen control chip 40 are electrically connected, and the automatic replacement of the pen core is completed.

[0042] See also Figure 4 In one embodiment, the side wall of the U-shaped receiving plate 204 is connected to the inner wall of the pen housing 10 through a guide assembly 90, and the guide assembly 90 is used to provide a guide for the movement of the U-shaped receiving plate 204 to improve the stability of the U-shaped receiving plate 204 during movement.

[0043] See also Figure 4 In one embodiment, the guide assembly 90 includes a guide rod 901, a third elastic member 902 and a guide block 903. The guide block 903 is fixedly arranged on the side wall of the U-shaped receiving plate 204. One end of the guide rod 901 is fixedly connected to the inner wall of the pen housing 10, and the other end passes through the guide block 903 and movably cooperates with the guide block 903. One end of the third elastic member 902 is connected to the inner wall of the pen housing 10, and the other end is connected to the guide block 903, so as to provide elastic pulling force to the guide block 903.

[0044] When the paddle 201 is pushed to drive the U-shaped receiving plate 204 to move, the guide block 903 adaptively slides along the outside of the guide rod 901. At this time, the third elastic member 902 is stretched. When the pen core falls to the inside of the U-shaped receiving plate 204, the paddle 201 can be released. At this time, the third elastic member 902 pulls the lower shell to drive the guide block 903 to slide in the opposite direction along the outside of the guide rod 901, thereby driving the U-shaped receiving plate 204 to move in the opposite direction. When the U-shaped receiving plate 204 moves in the opposite direction, it can drive the pen core inside it to move synchronously, so that one end of the pen core extends out of the opening at one end of the pen shell for writing operations.

[0045] See also Figure 4In one embodiment, an air storage chamber 105 is opened inside the pen housing 10, a first flexible layer 106 is provided on one side of the air storage chamber 105, an air storage channel 905 is opened inside the guide rod 901, a second flexible layer 904 is provided on the outer wall of the guide rod 901, one end of the air storage channel 905 is communicated with the inner area of ​​the second flexible layer 904, and the other end is communicated with the inside of the air storage chamber 105.

[0046] When the paddle 201 is pushed to drive the U-shaped receiving plate 204 to move, the guide block 903 is removed from the outside of the second flexible layer 904. At this time, the second flexible layer 904 expands outward to extract the air inside the gas storage chamber 105 into the gas storage channel 905, so that the first flexible layer 106 collapses, thereby releasing the clamping state of the pen core that needs to be replaced. At this time, the pen core that needs to be replaced can be smoothly pulled out from one end of the pen shell 10; when the U-shaped receiving plate 204 drives its inner pen core to extend to the outside of the pen shell 10, the second flexible layer 904 can re-enter the inside of the guide block 903 and be squeezed by the guide block 903, so that the air inside the gas storage channel 905 is pressed into the inside of the gas storage chamber 105, thereby driving the first flexible layer 106 to expand, and then clamping the replaced pen core to improve the stability of the replaced pen core when it extends to the outside of the pen shell 10.

[0047] In one embodiment, the first flexible layer 106 and the second flexible layer 905 may be rubber layers or silicone layers, which is not limited here.

[0048] See also Figure 1 In one embodiment, a guide rail 102 is fixedly provided on the inner wall of the pen housing 10 along the length direction, a guide rail groove adapted to the guide rail 102 is opened at one end of the baffle 701, and a first support block 103 is fixedly provided on the inner wall of the pen housing 10. The first support block 103 is connected to the baffle 701 through a first elastic member 703, and the first elastic member 703 is used to provide elastic support to the baffle 701.

[0049] When the paddle 201 is released and the third elastic member 902 drives the U-shaped receiving plate 204 to move in the reverse direction, the first elastic member 703 drives the baffle 701 to move in the reverse direction, so that the baffle 701 moves back to one end of the arc plate 60 to continue to block the subsequent pen cores.

[0050] In one embodiment, the first elastic member 703, the second elastic member 802 and the third elastic member 902 may be springs or metal springs, which are not limited here.

[0051] In the embodiment of the present invention, when the refill of the capacitive pen needs to be replaced, the receiving component 20 moves, thereby driving the limiting component 70 to move, so that the limiting component 70 is removed from one end of the arc plate 60 to release the limitation of several refills between the arc plate 60 and the pen shell 10. At this time, the pushing component 80 pushes several refills, so that a group of refills at the edge falls to the inside of the receiving component 20. Compared with the prior art, when a group of refills of the capacitive pen is damaged, the refills can be automatically and quickly replaced, which has the advantages of quick and convenient refill replacement and high replacement efficiency.

[0052] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
