Description

Technical Field

[0001] This invention relates to a stylus, and more particularly to a stylus with a rechargeable battery. Background Technology

[0002] With the development of touch technology, many electronic devices can be paired with styluses for touch input. However, for styluses with rechargeable lithium batteries, the batteries may become over-discharged and difficult to recharge directly after prolonged periods of inactivity. This means that users often need a considerable amount of time to activate the battery before the stylus can be charged successfully when using it for the first time. This situation leads to inconvenience in stylus use and may cause users to mistakenly believe that the stylus's charging function has malfunctioned. Summary of the Invention

[0003] This invention provides a stylus that can prevent its battery module from over-discharging.

[0004] The stylus of the present invention includes a pen body, a battery module, and a conductive structure. The pen body has a charging port. The battery module is disposed within the pen body and has at least one electrode. The conductive structure is disposed within the pen body and includes a first conductive component, a second conductive component, and a first conductive elastic element. The first conductive component is connected to the electrode, the second conductive component is disposed between the first conductive component and the charging port, and the first conductive elastic element is connected to the second conductive component and has a contact end. The contact end contacts the first conductive component by the elastic force of the first conductive elastic element, and the contact end is adapted to be separated from the first conductive component by an external force.

[0005] In one embodiment of the present invention, the first conductive elastic element is a torsion spring, and the contact end is one spring arm of the torsion spring.

[0006] In one embodiment of the present invention, the stylus includes a force-applying element, wherein the force-applying element extends into the pen body to push the contact end away from the first conductive component, and the force-applying element is adapted to move away from the pen body to release the contact end.

[0007] In one embodiment of the present invention, the force-applying element is a sheet-like element.

[0008] In one embodiment of the present invention, the pen body has a channel, and the force-applying element extends into the pen body through the channel.

[0009] In one embodiment of the present invention, the aforementioned channel extends from the inner wall of the charging port toward the first conductive component.

[0010] In one embodiment of the present invention, the aforementioned channel extends from the outer surface of the pen body toward the first conductive component.

[0011] In one embodiment of the present invention, the first conductive component includes a conductive element and a second conductive elastic element. The contact end contacts the conductive element through the elastic force of the first conductive elastic element, and the second conductive elastic element is connected between at least one electrode and the conductive element.

[0012] In one embodiment of the present invention, the second conductive elastic element is a compression spring.

[0013] In one embodiment of the present invention, the battery module includes a battery body and a circuit board, at least one electrode is disposed on the circuit board, and the battery body has at least one terminal and is connected to at least one electrode through the at least one terminal.

[0014] Based on the above, in the stylus of the present invention, one electrode of the battery module does not extend directly to the charging port of the pen body, but extends to the charging port through a conductive structure including a first conductive elastic element. When the stylus is not used for a long time, an external force can be applied to the first conductive elastic element, causing it to elastically deform and blocking the electrical connection of the conductive structure, thereby preventing over-discharge of the battery module. Thus, the user will not have difficulty charging the battery module due to over-discharge. Attached Figure Description

[0038] Figure 1 This is a partial cross-sectional view of a stylus according to an embodiment of the present invention. Please refer to it. Figure 1 The stylus 100 of this embodiment includes a pen body 110, a battery module 120, and a conductive structure 130. The pen body 110 has a charging port 110a. The battery module 120 is disposed within the pen body 110 and has an electrode 120a, which is, for example, one of the positive and negative terminals of the battery module 120. The battery module 120 may include a battery body 122 and a circuit board 124. The electrode 120a is disposed on the circuit board 124, and the battery body 122 has at least one terminal 1221 and is connected to the electrode 120a through the terminal 1221. The conductive structure 130 is disposed within the pen body 110 and located between the electrode 120a and the charging port 110a. The battery module 120 can be charged through the electrode 120a and the conductive structure 130.

[0039] Specifically, the conductive structure 130 includes a first conductive component 132, a second conductive component 134, and a first conductive elastic element 136. The first conductive component 132 is connected to the electrode 120a of the battery module 120. The second conductive component 134 is disposed between the first conductive component 132 and the charging port 110a, adjacent to the charging port 110a. The second conductive component 134 is, for example, an existing conductive terminal of the stylus 100 at the charging port 110a, used to connect an external charging connector at the charging port 110a. The first conductive elastic element 136 is connected to the second conductive component 134 and has a contact end 136a. The contact end 136a contacts the first conductive component 132 through the elastic force of the first conductive elastic element 136, so that the electrode 120a of the battery module 120 is electrically connected to the second conductive component 134 through the first conductive component 132 and the first conductive elastic element 136. In this state, the user can insert the external charging connector into the charging port 110a and connect it to the second conductive component 134 through the internal charging connector 138 to charge the battery module 120.

[0040] Figure 2 Draw Figure 1 The contact end of the first conductive elastic element is separated from the first conductive assembly. Please refer to... Figure 2 The stylus 100 in this embodiment also includes a force-applying element 140, which can be used as follows: Figure 2 The force-applying element 140 extends into the pen body 110 and applies an external force to the contact end 136a of the first conductive elastic element 136, causing the contact end 136a to be pushed away from the first conductive assembly 132 by this external force. When the force-applying element 140 moves away from the pen body 110, the contact end 136a of the first conductive elastic element 136 is released and returns to its original position. Figure 1 The state shown.

[0041] As described above, in the stylus 100 of this embodiment, the electrode 120a of the battery module 120 does not extend directly to the charging port 110a of the pen body 110, but extends to the charging port 110a through a conductive structure 130 including a first conductive elastic element 136. When the stylus 100 is not used for a long time, it can... Figure 2 As shown, the force-applying element 140 applies an external force to the first conductive elastic element 136, causing it to elastically deform and thus blocking the electrical connection of the conductive structure 130, thereby preventing the battery module 120 from over-discharging. Therefore, the user will not have difficulty charging the battery module 120 due to over-discharge.

[0042] In other embodiments, the first conductive elastic element 136 can be subjected to force in other ways to break its contact with the first conductive component 132, and the present invention is not limited thereto. Furthermore, the present invention does not limit the form of the first conductive elastic element 136; the first conductive elastic element 136 can be as follows: Figure 1 and Figure 2 The image shows a torsion spring, with contact end 136a being one of the spring arms. In other embodiments, the first conductive elastic element may be other suitable forms of elastic element.

[0043] In this embodiment, the force-applying element 140 is, for example, a sheet-like element made of Mylar sheet or other plastic material. Furthermore, the pen body 110 has a channel 110b extending from the inner wall of the charging port 110a towards the first conductive component 132. The sheet-like force-applying element 140 can enter the channel 110b from the charging port 110a, and be guided into the pen body 110 by the channel 110b. In other embodiments, the force-applying element 140 may have other suitable shapes and may be inserted into the pen body 110 by other suitable means; the present invention is not limited thereto.

[0044] In this embodiment, the first conductive component 132 includes a conductive element 1321 and a second conductive elastic element 1322. The conductive element 1321 is, for example, a conductive metal tube or other form of conductive element, and the second conductive elastic element 1322 is, for example, a conductive metal compression spring or other form of conductive elastic element. The contact end 136a of the first conductive elastic element 136 contacts the conductive element 1321 through the elastic force of the first conductive elastic element 136. The second conductive elastic element 1322 is connected between the electrode 120a and the conductive element 1321, thus absorbing manufacturing and assembly tolerances of the components through the elastic deformation capability of the second conductive elastic element 1322, and ensuring reliable contact between the second conductive elastic element 1322 and the conductive element 1321. Figure 1 and Figure 2 In the diagram, the electrode 120a in the circuit board 124 is schematically shown with dashed lines. The electrode 120a can actually be a circuit layer in the circuit board 124 and directly contacts the end of the second conductive elastic element 1322. In other embodiments, the first conductive component 132 can be a single-piece conductive metal piece, rather than being composed of the conductive element 1321 and the second conductive elastic element 1322. Furthermore, in this embodiment, the second conductive component 134 can be part of the circuit board 124 and contains wiring for electrically connecting the first conductive elastic element 136 to the internal charging connector 138. In other embodiments, the second conductive component 134 can be other suitable conductive components, and the present invention is not limited thereto.

[0045] Figure 3This is a partial cross-sectional view of a stylus according to another embodiment of the present invention. Figure 3 The stylus 100A shown is Figure 2 The stylus 100 shown differs in that, in stylus 100A, the channel 110b for guiding the force-applying element 140 extends from the outer surface 110c of the pen body 110 towards the first conductive component 132, rather than as shown in the diagram. Figure 2 As shown, it extends from the inner wall of the charging port 110a towards the first conductive component 132. That is, in this embodiment, the channel 110b and the charging port 110a are set independently of each other, and the force-applying element 140 does not enter the channel 110b from the charging port 110a, but directly from the outer surface 110c of the pen body 110 into the channel 110b.

[0046] In summary, in the stylus of this invention, one electrode of the battery module does not extend directly to the charging port of the pen body, but rather extends to the charging port through a conductive structure including a first conductive elastic element. When the stylus is not used for an extended period, a force-applying element can be inserted into the pen body to apply external force to the first conductive elastic element, causing it to elastically deform and disrupting the electrical connection of the conductive structure, thereby preventing over-discharge of the battery module. Thus, the user will not experience difficulty charging the battery module due to over-discharge.
