Description

Technical Field

[0001] This utility model relates to a novel active capacitive pen with a removable battery, and belongs to the technical field of active capacitive pen devices. Background Technology

[0002] A capacitive pen is a pen made of conductive materials that has conductive properties and is used to touch capacitive screens to complete human-computer interaction. The capacitive pen is an auxiliary device that uses conductive materials to mimic the human body (usually the finger) to complete human-computer interaction. With the development of apps, today's capacitive pens are no longer simply replacing finger operation functions, but are increasingly used on mobile devices.

[0003] Existing capacitive pens are powered in two ways: one uses a built-in rechargeable battery, and the other uses a replaceable battery. Pens with built-in rechargeable batteries can be charged by a charger when the battery is low, allowing for longer use. However, there are situations where a charger is not available, affecting the pen's usability. Furthermore, existing rechargeable pens only have a protective cover for the charging port, lacking other protective structures; some even lack a cover altogether, leaving the charging port exposed, compromising safety and aesthetics. Pens with replaceable batteries can be used directly by replacing the battery when it's low, reducing battery anxiety to some extent. However, most of these pens lack a charging mechanism, preventing battery charging and only allowing battery replacement. Even when a battery is unavailable, battery replacement is not possible, still contributing to battery anxiety. Therefore, this paper proposes a novel active capacitive pen with a removable battery to address the problems of existing technologies. Utility Model Content

Detailed Implementation

[0029] See Figures 1-11 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a main bracket 1, which includes a motherboard bracket 1001 and a battery slot 1002. A motherboard 2 is provided on one side of the motherboard bracket 1001, and an FPC cable 5 is provided at the end of the motherboard 2, which passes through to the end of the battery slot 1002. In this embodiment, a battery slot is provided for installing a battery. The motherboard end is the negative terminal, and the end of the battery slot is the positive terminal. The battery is mainly a rechargeable battery, which can be charged and used when it is convenient to charge. When it is inconvenient to charge, the battery can be replaced. Conventional non-rechargeable batteries can also be used. The variety of choices brings a better user experience, and the reuse of rechargeable batteries can also effectively reduce environmental pollution.

[0030] A tail bracket 8 is provided at the end of the battery compartment 1002. A power board 7 with a charging port is provided inside the tail bracket 8 and electrically connected to the FPC cable 5. A threaded metal ring 6 is provided in the middle of the main bracket 1. A pen tube 9 with a metal conductive layer on the inner wall is provided outside the battery compartment 1002 and connected to the threaded metal ring 6. A pen clip 10 is rotatably provided at the end of the pen tube 9 and is movably connected to the tail bracket 8. In this embodiment, in order to reduce the wiring, reduce production costs, and improve assembly efficiency, a threaded metal ring is used as an intermediate conductive component. The threaded metal ring is electrically connected to the main board, the FPC cable is electrically connected to the power board, and the pen tube with a metal conductive layer on the inner wall is electrically connected to the power board. The pen tube is then connected to the threaded metal ring to complete the conduction of the entire circuit. Moreover, the integrated conductive structure has lower resistance, higher conductivity, and faster response speed of the capacitive pen, which can bring users a more sensitive operating experience.

[0031] More specifically, the motherboard 2 is electrically connected to a negative spring 12 at its end. A first conductive spring 201 is provided on the motherboard 2 near the negative spring 12. The first conductive spring 201 contacts the inner wall of the threaded metal ring 6. The main support 1 also includes a metal ring sleeve 1003 connecting the motherboard support 1001 and the battery slot 1002. A spring slot 1004 is provided on the metal ring sleeve 1003 to cooperate with the first conductive spring 201. In order to realize the electrical connection between the threaded metal ring and the motherboard, a first conductive spring is provided on the motherboard. One end of the first conductive spring is welded to the motherboard, and the other end passes through the spring slot on the main support and is electrically connected to the inner wall of the threaded metal ring.

[0032] More specifically, the battery slot 1002 is provided with an electrode plate slot 1005 at its end. The inner side of the electrode plate slot 1005 is an open structure that matches the positive terminal of the battery 13. By providing the electrode plate slot, the end of the FPC line can be fixed. At the same time, the opening on the inner side of the electrode plate slot is used to prevent the positive and negative terminals of the battery from being reversed. It serves as a reminder and limiting structure to limit and fix the positive terminal of the battery.

[0033] More specifically, the power board 7 has two connected elastic electrode plates 701 at its front end, both of which are positive terminals, one on the inside and one on the outside. The FPC line 5 has a battery polarity plate 501 at its end. The battery polarity plate 501 has a concentric circle structure, with the inner layer being the positive terminal and the outer layer being the positive and negative terminals, and is connected to the two elastic electrode plates 701 respectively. The dual electrical connection structure can ensure the stability of the electrical connection and prevent poor contact.

[0034] Furthermore, a second conductive spring 702 is provided on one side of the elastic electrode sheet 701, which contacts the inner wall of the pen tube 9. The entire circuit is realized by connecting the pen tube through the second conductive spring and then connecting the threaded metal ring with the first conductive spring and the main board. The pen tube part of the circuit is the negative part.

[0035] More specifically, the tail bracket 8 includes a power board mounting slot 804 in the main body, which is used for fixing the power board. Symmetrical pen clip limiting claws 801 are provided at the end of the power board mounting slot 804. Due to the split structure, the whole is elastic, facilitating connection and disassembly. Limiting protrusions 802 are provided at the outer end of the pen clip limiting claws 801, and limiting edges 803 with vertical surfaces on both sides are provided at the front end of the pen clip limiting claws 801. Two pen clip limiting claws 801 extend through the pen tube 9 and connect to the pen clip 10. The pen clip 10 has an L-shaped cross-section, with a recessed button groove 101 at the vertical end. Four symmetrical positioning grooves 102 are provided on the inner wall of the bottom of the button groove 101. Symmetrical positioning grooves 102 are provided above the center space of adjacent two positioning grooves 102 in the vertical direction. There are two positioning blocks 103. The positioning groove 102 matches the limiting protrusion 802. The positioning block 103 cooperates with the limiting edge 803. The rotation angle of the pen clip is 0-90 degrees. That is, in the initial state, the main body of the pen clip covers the charging port. It can be understood that the charging port is equipped with a dust cover. When the pen clip is rotated 90 degrees, all positioning grooves rotate 90 degrees. At this time, the positioning groove gradually changes from the state of being engaged with the limiting protrusion to the state of being separated, and then to the state of being engaged with the limiting protrusion at the other end, thus limiting the position. In the initial state, the two positioning blocks abut against the vertical surface of one side of the two limiting edges respectively to achieve positioning and cannot rotate excessively. During the opening process, they separate from the original limiting edge and abut against the vertical surface of the other limiting edge to continue to achieve the positioning function, thereby achieving the blocking and opening of the charging port.

[0036] More specifically, a button 11 is provided in the button slot 101. The button 11 passes through two pen clip limiting claws 801 and engages with the side wall of the power board mounting slot 804. The button is both a switch trigger button and a constraint member for the pen clip. By engaging the button with the power board mounting slot on the tail bracket, the pen clip is constrained and limited, so that the pen clip cannot be disengaged in the axial direction and can only rotate in the radial direction.

[0037] More specifically, the motherboard bracket 1001 is fitted with a shielding sleeve 3 on its outer layer. The shielding sleeve shields the motherboard to prevent external signal interference. The outer surface of the shielding sleeve 3 is a polygonal structure. The shielding sleeve 3 is covered with a front shell 4. Understandably, the inner wall of the front shell is a polygonal structure corresponding to the outer surface of the shielding sleeve, which constrains the front shell. At the same time, the front end of the front shell is connected to the pen tip installed on the main bracket. The rear end of the front shell 4 is threadedly connected to the front end of the threaded metal ring 6, so that both ends of the front shell are fixed.

[0038] More specifically, the power board 7 integrates a power management module, and a control switch and button 11 are provided at the end of the power board 7. The power management module enables the charging management of the battery and the power supply management of the motherboard. Pressing the button will simultaneously press the control switch to turn the power on and off.

[0039] The working principle of this utility model is as follows: In use, rotating the pen tube 9 removes the pen clip 10 and the tail bracket 8 together. The battery 13 is then inserted into the battery mounting slot 1002, and the pen tube 9 is reinstalled. The two elastic electrode plates 701 are electrically connected to the battery polarity plate 501. After the pen tube 9 is connected to the threaded metal ring 5, it is electrically connected to the first conductive spring 201, thereby realizing the electrical connection between the main board 2 and the power board 7. There is no need to run wiring inside the pen body, which saves production costs, facilitates assembly and production, and improves the yield rate. When there is no battery to replace, the battery can be charged by connecting a charging cable through the charging port on the power board 7, so that the battery can be replaced and charged at the same time. After charging is completed, rotating the pen clip 10 causes the positioning block 103 to abut against the vertical surface of the limiting edge 803, and the limiting protrusion 802 falls into the positioning slot 102. The pen clip covers the charging port, which protects the charging port and improves the overall aesthetics.

[0040] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
