[0024] The present application provides a capacitive stylus charging system, a capacitive stylus, and an electronic device assembly, each of which is described in detail below.

[0025] A capacitive stylus is a smart device with touch and writing functions, commonly used in tablets, smartphones, and other touchscreen devices. To maintain proper operation, a capacitive stylus requires regular charging. However, charging requires checking that the charging area of the stylus is correctly connected to the electrodes of the charging electronic device. This increases the complexity of the charging process. To improve the accuracy of the connection between the charging area of the stylus and the electrodes of the charging electronic device, one approach could be to optimize the slot structure of the stylus or the charging electronic device. By properly designing the slot shape and electrode position, the stylus can more easily connect to the charging port when inserted, further improving charging reliability and convenience. However, such an optimization may increase product design cost and solution complexity, as the slots of the stylus and the charging electronic device must be redesigned, including adjustments to shape, size, and electrode position. This may require additional engineering design and manufacturing process improvements, increasing product development and production costs. Furthermore, optimizing the slot structure also requires considering compatibility with existing devices. If the slot structure changes lead to incompatibility with existing devices, users may need to purchase a new charging electronic device or capacitive stylus, increasing costs and inconvenience.
[0026] In view of this, an embodiment of the present application provides a charging system for a capacitive pen, which is used to charge through an electronic device. The electronic device includes a first electrode and a second electrode. The present application uses an anti-reverse module to connect the charging loop between the first electrode, the second electrode and the charging module, thereby ensuring the correct connection between the first charging contact and the second charging contact electrodes during the charging process. There is no need to limit the connection relationship between the first charging contact and the second charging contact and the electrodes, so that the charging system can flexibly adapt to the connection methods of different electrodes, avoiding the problem of charging failure caused by incorrect electrode connection during charging, and making the charging process simpler and more reliable.

[0029] In some embodiments, the first charging contact 11 contacts one of the positive power supply electrode and the negative power supply electrode, and the second charging contact 12 contacts the other of the positive power supply electrode and the negative power supply electrode.
[0030] In this application, capacitive pen contact charging is a method of charging through contact point contact.

There is no need for cumbersome cable connections or specific charging bases, which greatly improves the flexibility and convenience of use.
[0031] In some embodiments, when the first charging contact 11 is connected to the first electrode and the second charging contact 12 is connected to the second electrode, the first charging contact 11 and the second charging contact 12 pass through the anti-reverse module 20, and the charging loop is conducted between the first electrode, the second electrode and the charging module 30 through the anti-reverse module 20, so that the electronic device charges the charging module 30 through the charging loop.
[0032] In some embodiments, when the first charging contact 11 is connected to the second electrode and the second charging contact 12 is connected to the first electrode, the first charging contact 11 and the second charging contact 12 pass through the anti-reverse module 20, and the charging loop is conducted between the first electrode, the second electrode and the charging module 30 through the anti-reverse module 20, so that the electronic device can charge the charging module 30 through the charging loop.
[0033] Through the above technical solution, the present application connects the charging loop between the first electrode, the second electrode and the charging module 30 through the anti-reverse module 20, ensuring the correct connection of the first charging contact 11 and the second charging contact 12 electrodes during the charging process. There is no need to limit the connection relationship between the first charging contact 11 and the second charging contact 12 and the electrodes, so that the charging system can flexibly adapt to different electrode connection methods, avoiding the problem of charging failure caused by incorrect electrode connection during charging and damage to the internal circuit of the capacitive stylus caused by incorrect charging electrode connection, making the charging process simpler and more reliable. In addition, charging can be achieved directly through the existing charging contacts of the capacitive stylus, without the need for special design of the charging structure of the capacitive stylus or charging electronic equipment, and the structure is simple.
[0034] See also Figure 2 , Figure 2 Another example structural diagram of a charging system provided in an embodiment of the present application. The anti-reverse module 20 includes: a first anti-reverse unit 21, a first charging contact 11, the first anti-reverse unit 21, a charging module 30, and a second charging contact 12 forming a first charging circuit; a second anti-reverse unit 22, a first charging contact 11, the second anti-reverse unit 22, the charging module 30, and the second charging contact 12 forming a second charging circuit; wherein, when the first charging contact 11 is connected to the first electrode, the first anti-reverse unit 21 is turned on and the second anti-reverse unit 22 is turned off, so as to charge the charging module 30 through the first charging circuit; when the first charging contact 11 is connected to the second electrode, the second anti-reverse unit 22 is turned on and the first anti-reverse unit 21 is turned off, so as to charge the charging module 30 through the second charging circuit.
[0035] In the present application, a first charging circuit is formed based on the first charging contact 11, the first anti-reverse unit 21, the charging module 30 and the second charging contact 12, and a second charging circuit is formed based on the first charging contact 11, the second anti-reverse unit 22, the charging module 30 and the second charging contact 12, and then when the first anti-reverse unit 21 is turned on, the first charging circuit is turned on, and when the first anti-reverse unit 21 is turned off, the first charging circuit is not turned on; when the second anti-reverse unit 22 is turned on, the second charging circuit is turned on, and when the second anti-reverse unit 22 is turned off, the second charging circuit is not turned on; and then, based on the conduction of the first charging circuit or the second charging circuit, the first electrode and the second electrode are connected to the ports corresponding to the first electrode and the second electrode in the charging module 30 through the anti-reverse module 20, thereby achieving the purpose of charging the capacitive pen.
[0036] Through the above technical solution, the present application enables the corresponding first charging circuit or the second charging circuit to be turned on and off by turning on and off the first anti-reverse unit 21 or the second anti-reverse unit 22, thereby ensuring the correct connection between the first charging contact 11 and the second charging contact 12 electrodes during the charging process. There is no need to limit the connection relationship between the first charging contact 11 and the second charging contact 12 and the electrodes, so that the charging system can flexibly adapt to the connection methods of different electrodes.
[0037] In some embodiments, the charging module 30 includes an input port 31 and an output port 32; the first anti-reverse unit 21 includes a first unidirectional conductive member 211 and a second unidirectional conductive member 212, the input end of the first unidirectional conductive member 211 is connected to the first charging contact 11, the output end of the first unidirectional conductive member 211 is connected to the input port 31, the input end of the second unidirectional conductive member 212 is connected to the output port 32, and the output end of the second unidirectional conductive member 212 is connected to the second charging contact 12; the second anti-reverse unit 22 includes a third unidirectional conductive member 221 and a fourth unidirectional conductive member 222, the input end of the third unidirectional conductive member 221 is connected to the second charging contact 12, the output end of the third unidirectional conductive member 221 is connected to the input port 31, the input end of the fourth unidirectional conductive member 222 is connected to the output port 32, and the output end of the fourth unidirectional conductive member 222 is connected to the first charging contact 11.
[0038] In the present application, the input port 31 of the charging module 30 is a port corresponding to the positive power supply electrode, and the output port 32 of the charging module 30 is a port corresponding to the negative power supply electrode. The first charging circuit or the second charging circuit is connected, so that the positive power supply electrode is connected to the input port 31, and the negative power supply electrode is connected to the output port 32. That is, the first electrode is connected to the input port 31 through the anti-reverse module 20, and the output port 32 is connected to the second electrode through the anti-reverse module 20, so that the charging loop is connected between the first electrode, the second electrode and the input port 31 and the output port 32 of the charging module 30.
[0039] For example, taking the first electrode connected to the first charging contact 11 and the second electrode connected to the second charging contact 12 as an example, at this time, the first electrode is configured as the positive power supply electrode, and the second electrode is configured as the negative power supply electrode. The charging loop process between the first electrode, the second electrode and the charging module 30 is as follows: the first electrode is connected to the first charging contact 11, and the first charging contact 11 is connected to the input port 31 via the first unidirectional conductive member 211. Based on the unidirectional conductivity of the first unidirectional conductive member 211, at this time, the fourth unidirectional conductive member 222 is cut off, then The first electrode is connected to the input port 31; the second electrode is connected to the second charging contact 12, and the second charging contact 12 is connected to the output port 32 via the second unidirectional conductive member 212. Based on the unidirectional conductivity of the second unidirectional conductive member 212, at this time, the third unidirectional conductive member 221 is cut off, and the second electrode is connected to the output port 32; then the charging current flows from the first electrode to the first unidirectional conductive member 211 and then to the input port 31, and then from the output port 32 through the second unidirectional conductive member 212 to the second electrode, forming a charging loop for the pen tip.
[0040] In some embodiments, the first unidirectional conductive member 211, the second unidirectional conductive member 212, the third unidirectional conductive member 221, and the fourth unidirectional conductive member 222 are all diodes, wherein the anode of the diode is configured as the input terminal of the unidirectional conductive member, and the cathode of the diode is configured as the output terminal of the unidirectional conductive member.
[0041] It should be noted that the one-way conducting member in the present application may also be other devices with one-way conduction.
[0042] Through the above technical solution, the anti-reverse module 20 includes a first unidirectional conductive member 211 and a second unidirectional conductive member 212. Based on the unidirectional conductivity of the unidirectional conductive member, when the first electrode is connected to the first charging contact 11 and the second electrode is connected to the second charging contact 12, based on the conduction of the first unidirectional conductive member 211 and the second unidirectional conductive member 212, the first electrode, the input port 31, the output port 32, and the second electrode are connected to the charging loop; In addition, the anti-reverse module 20 also includes a third unidirectional conductive member 221 and a fourth unidirectional conductive member 222, so that the first electrode is connected to the second charging contact 12, When the second electrode is connected to the first charging contact 11, the third unidirectional conductive member 221 and the fourth unidirectional conductive member 222 are conductive, thereby connecting the first electrode, the input port 31, the output port 32, and the second electrode to the charging loop. Furthermore, the anti-reverse module 20 of the present application can ensure that, regardless of whether the first charging contact 11 is connected to one of the first and second electrodes and the second charging contact 12 is connected to the other of the first and second electrodes, the charging loop between the first and second electrodes and the charging module 30 is connected, thereby enabling the electronic device to charge the charging module 30 through the charging loop. Furthermore, the unidirectional conductivity of the unidirectional conductive member prevents the occurrence of reverse current. This unidirectional conductivity design makes the charging process more stable and reliable, eliminating the need for additional control mechanisms to control the current direction. This simplifies the circuit scheme, reduces the number and complexity of required components, and lowers the manufacturing cost of the circuit board.
[0043] See also Figure 3 as well as Figure 4 , Figure 3 This is a schematic diagram of an exemplary structure of a capacitive stylus pen housing provided in an embodiment of the present application. Figure 4 This is a schematic diagram of an exemplary structure of a capacitive stylus charging system according to an embodiment of the present application. In some embodiments, the capacitive stylus comprises a housing 40, within which the anti-reverse module 20 is disposed. The housing 40 includes a first through-hole 41, through which the first charging contact 11 is connected to the anti-reverse module 20; and a second through-hole 42, through which the second charging contact 12 is connected to the anti-reverse module 20.
[0044] In some embodiments, the first charging contact 11 and the second charging contact 12 are arranged on the outer wall of the pen housing 40 and can surround the outer wall of the pen housing 40, wherein the first charging contact 11 and the second charging contact 12 do not contact each other and can be respectively arranged at relatively upper and lower positions on the outer wall of the pen housing 40 along the central axis x direction.
[0045] Through the above technical solution, the first charging contact 11 and the second charging contact 12 are arranged on the outer wall of the pen housing 40 of the capacitive stylus, facilitating contact charging of the capacitive stylus. The first charging contact 11 and the second charging contact 12 are arranged on the outer wall of the pen housing 40 and can surround the outer wall of the pen housing 40 to achieve all-round contact charging. This allows the capacitive stylus to rotate around the first direction as an axis, regardless of how many degrees, so that the components transmitting the first and second electrodes in the electronic device can contact and connect with the first charging contact 11 and the second charging contact 12 during charging. In addition, the first charging contact 11 and the second charging contact 12 can also be arranged at any position on the outer wall of the pen housing 40 of the capacitive stylus based on design requirements, thereby achieving the effect of charging the capacitive stylus and providing a convenient, flexible and reliable charging experience.
[0046] In some embodiments, the pen housing 40 has a first direction perpendicular to the central axis, and the first charging contact 11 and the second charging contact 12 are symmetrically arranged on the outer wall of the pen housing 40 along the first direction.
[0047] In some embodiments, the capacitive pen has a first direction perpendicular to the central axis as the y direction, and the first charging contact 11 and the second charging contact 12 can be embedded in the outer wall of the pen housing 40, so that the components that transmit the first electrode and the second electrode in the electronic device can be in contact and connected with the first charging contact 11 and the second charging contact 12 during charging.
[0048] In some embodiments, in order to facilitate charging, the cross-section of the pen housing 40 along the first direction can be designed to be an elliptical shape. The first direction can be the direction of the short axis of the ellipse, and the first direction can also be the direction of the long axis of the ellipse.
[0049] It should be understood that in order for the capacitive pen to work properly, the pen case 40 in this application has a accommodating cavity for accommodating the anti-reverse module 20, the charging module 30, and the energy storage device in the capacitive pen; and then the first charging contact 11 and the second charging contact 12 are arranged on the outer wall of the pen case 40, and need to penetrate the outer wall of the pen case 40 to connect with the anti-reverse module 20 inside the pen case 40.
[0050] Through the above technical solution, the first charging contact 11 and the second charging contact 12 are arranged on the outer wall of the pen housing 40 of the capacitive stylus, facilitating contact charging of the capacitive stylus. The user only needs to contact the pen housing of the capacitive stylus with the charging device to achieve charging, without the need for additional operating steps. In addition, the present application does not require additional design of the first charging contact 11 and the second charging contact 12. The charging system can flexibly adapt to different electrode connection methods, and no anti-foolproof design is required for the appearance, making the charging process simpler and faster. The first charging contact 11 and the second charging contact 12 are symmetrically arranged on the outer wall of the pen housing 40 along the first direction. The symmetrical position design allows the capacitive stylus to be placed more stably on the charging base during charging, reducing shaking or slipping caused by the center of gravity offset, thereby improving the stability of the charging process. The symmetrical charging contact parts can ensure that the contact area between the capacitive stylus and the charging base is uniform, making the current transmission more stable and reducing the situation of reduced charging efficiency or charging interruption caused by poor contact. In addition, the pen housing 40 has an elliptical cross-section, with different axial lengths in two directions. This helps ensure that the first charging contact 11 and the second charging contact 12 on the capacitive stylus accurately contact the components of the electronic device that transmit the first and second electrodes. This accurate contact ensures the stability of the charging effect and improves the charging speed. Furthermore, based on the characteristics of the elliptical shape, the capacitive stylus can be placed more stably on the charging dock during charging.

[0055] In some embodiments, the first connecting member 50 and the second connecting member 60 may be in a sheet-like structure or in other space-saving structural shapes.
[0056] Through the above technical solution, the first charging contact 11 is connected to the anti-reverse module 20 via the first connector 50, and the second charging contact 12 is connected to the anti-reverse module 20 via the second connector 60. This design makes the connection between the first and second charging contacts 11, 12 and the anti-reverse module 20 more convenient. Regardless of the position of the first and second charging contacts 11, 12, they can be connected to the anti-reverse module 20. This design avoids the increased difficulty of connection due to location issues and improves the flexibility and convenience of the connection. Specifically, the first and second connectors 50, 60 are arranged between the bracket and the pen housing 40. This design increases the space utilization within the pen housing 40, allowing for better utilization of the internal space of the capacitive stylus. Furthermore, the first and second connectors 50, 60 adopt a sheet-like structure, which not only achieves the function of conductive connection but also reduces space occupancy. This design makes the overall structure of the capacitive stylus more compact and efficient. In addition, the first charging contact 11 is snap-fitted to the first extension portion 52 so that the first charging contact 11 is connected to the first connector 50, and the second charging contact 12 is snap-fitted to the second extension portion 62 so that the second charging contact 12 is connected to the second connector 60. The snap-fitted first charging contact 11 and the second charging contact 12 can be firmly set on the capacitive pen and connected to the first connector 50 and the second connector 60; at the same time, this design also makes the first charging contact 11 and the second charging contact 12 detachable, which facilitates the disassembly and use of the capacitive pen.
