Description

Technical Field

[0001] This application relates to the technical field of touch devices, and more specifically, to a capacitive pen. Background Technology

[0002] The advent of capacitive pens has provided users with greater convenience. Capacitive pens enable writing on capacitive touchscreens; their basic principle is to achieve coordinate positioning by generating capacitance changes between the pen and the touchscreen.

[0003] In existing technologies, capacitive pens are primarily stored and carried by magnetically attaching to the side of a tablet. Capacitive pens are divided into wired charging pens and wireless charging pens. When charging a wired charging pen, the user typically needs to manually align the charging cable with the pen cap to ensure electrical connection between the charging port on the cap and the cable. While wired charging is low-cost, it is dependent on the charging cable; if the cable is lost, charging is impossible. Wireless charging pens require a matching wireless charging setup, which is costly and slow. The aforementioned magnetic pens are easily dropped due to external impacts, leading to loss, and their charging methods suffer from high cost and slow charging speeds. Utility Model Content

[0004] This application provides a capacitive pen that can be directly plugged into a device interface to charge the pen. This charging method is simple to operate, wire-free, low-cost, and fast, while also solving the problem of carrying the capacitive pen and tablet at the same time.

[0005] The capacitive pen provided in this application adopts the following technical solution:

[0007] The pen body includes a housing, a mounting bracket, a control board, and a battery. The housing has a mounting chamber, and the control board, the battery, and the mounting bracket are disposed in the mounting chamber.

[0008] A charging assembly includes a charging interface electrically connected to the control board, the charging interface being disposed corresponding to the mounting hole, and the charging interface being movably disposed on the mounting bracket to be received in the mounting chamber from the mounting hole.

[0009] Optionally, the charging assembly further includes a fixed base and a rotating shaft. The fixed base is fixedly disposed on the mounting frame, one end of the rotating shaft is disposed on the mounting frame, and the other end is disposed on the fixed base. The charging interface is disposed on the fixed base through the rotating shaft, and the charging interface rotates with the fixed base about the rotating shaft.

[0010] Optionally, the mounting hole is configured as a through hole, allowing the charging interface to be screwed out through a lateral opening in the mounting hole.

[0011] Optionally, a damping element is provided between the charging interface and the rotating shaft, and the charging interface rotates with the damping element and the rotating shaft.

[0012] Optionally, the mounting base is provided with a conductive sheet, the conductive sheet is provided with a first connecting end and a second connecting end, the first connecting end is electrically connected to the charging interface, and the second connecting end is electrically connected to the control board.

[0018] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0019] When the capacitive pen needs charging, the charging interface protrudes from the mounting hole, allowing it to directly connect to the power supply for charging and storage in the battery.

[0030] This application provides a capacitive pen that can be directly plugged into a device interface to charge the pen. This charging method is simple to operate, wire-free, low-cost, and fast, while also solving the problem of carrying the capacitive pen and tablet at the same time.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Please see Figure 1 and Figure 2This is one embodiment of a capacitive pen in this application. The capacitive pen includes a pen body 1 and a charging component 2. The charging component 2 is used to connect to a power supply device to supply power to the pen body 1. In this embodiment, the power supply device can be a tablet computer. When the charging component 2 is electrically connected to the interface of the tablet computer, it can charge the pen body 1.

[0034] Please see Figure 3 and Figure 4 Specifically, the pen body 1 includes a housing 11, a mounting bracket 12, a control board 13, and a battery 14. A mounting chamber 111 is provided within the housing 11. The control board 13, battery 14, and mounting bracket 12 are disposed within the mounting chamber 111. The control board 13 is electrically connected to the battery 14 and is respectively mounted on the mounting bracket 12. A mounting hole 112 is provided on the peripheral wall of the housing 11, communicating with the mounting chamber 111. The charging assembly 2 includes a charging interface 21, which is electrically connected to the control board 13 and is positioned corresponding to the mounting hole 112. The charging interface 21 is movably disposed on the mounting bracket 12 to be housed within the mounting chamber 111 from the mounting hole 112. In this embodiment, the charging interface 21 is used to adapt to the interface of a tablet computer, and the charging interface 21 can be a USB interface, a Type-C interface, or an MFI interface, etc.

[0035] When the capacitive pen needs charging, the charging interface 21 protrudes from the mounting hole 112. At this time, the capacitive pen is in state 1, as shown below. Figure 1 As shown, the charging interface 21 can be plugged into a power supply device to establish an electrical connection, thereby charging and storing the charge in the battery 14; after charging is completed, the electrical connection between the charging interface 21 and the power supply device is disconnected, and the charging interface 21 is retracted from the mounting hole 112 into the mounting chamber 111. At this time, the capacitive pen is in state 2, as shown. Figure 2 As shown, this avoids the inconvenience caused by the presence of the charging port 21 when using the capacitive pen. In this application, a tablet computer can be used as a power supply device to power the capacitive pen. The capacitive pen can be directly plugged into the interface of the tablet computer through the charging port 21, thereby realizing the tablet computer charging the capacitive pen. This charging method is simple to operate, does not rely on wires, is low in cost, has a fast charging speed, and is easy to store. On the other hand, while the charging port 21 is plugged into the interface of the tablet computer for charging, the capacitive pen can be fixed on the tablet computer, solving the problem of the capacitive pen being easily lost or forgotten to be carried.

[0036] Please see Figure 4 and Figure 5In this embodiment, the charging interface 21 is rotatably connected to the mounting bracket 12, allowing the charging interface 21 to be rotated out from the mounting hole 112. In other embodiments, the charging interface 21 can also be stored in the mounting chamber 111 by pressing to pop it out or pulling it out. Specifically, to achieve the rotational engagement between the charging interface 21 and the mounting bracket 12, the charging assembly 2 further includes a fixed base 22 and a rotating shaft 23. The fixed base 22 is fixedly mounted on the mounting bracket 12, and one end of the rotating shaft 23 is mounted on the mounting bracket 12, while the other end is mounted on the fixed base 22. The charging interface 21 is mounted on the fixed base 22 via the rotating shaft 23, and the charging interface 21 rotates around the rotating shaft 23 with the fixed base 22. The arrangement of the rotating shaft 23 and the fixed base 22 enhances the installation stability of the charging interface 21. In this embodiment, the mounting bracket 12 is provided with a mounting space 121 to accommodate the charging interface 21 and the fixing base 22. The mounting space 121 is correspondingly provided with the mounting hole 112. When the charging interface 21 is located in the mounting space 121, the charging interface 21 is located between the fixing base 22 and the mounting bracket 12, which is intended to limit the charging interface 21 in the thickness direction of the capacitive pen and reduce the shaking of the charging interface 21.

[0037] The electrical connection between the charging interface 21 and the control board 13 is achieved through the mounting base 22. Specifically, the mounting base 22 is provided with a conductive sheet 221, which has a first connection end 2211 and a second connection end 2212. The first connection end 2211 is electrically connected to the charging interface 21, and the second connection end 2212 is electrically connected to the control board 13. Current flows through the charging interface 21, sequentially through the first connection end 2211 and the second connection end 2212, and thus reaches the control board 13.

[0038] Furthermore, to ensure that the charging interface 21 maintains electrical connection with the first connecting end 2211 throughout its rotation, the first connecting end 2211 is provided with a clearance groove 222 corresponding to the fixing base 22. The first connecting end 2211 is at least partially located outside the clearance groove 222. While the charging interface 21 rotates and connects with the first connecting end 2211, it presses against the first connecting end 2211. It is understood that when the charging interface 21 is installed on the fixing base 22, due to the limitation of the installation space 121, the charging interface 21 is always in contact with the end face of the fixing base 22. The fact that the first connecting end 2211 is at least partially located outside the clearance groove 222 reduces the distance between the charging interface 21 and the end face of the fixing base 22, thus ensuring that the first connecting end 2211 and the charging interface 21 remain pressed together. This allows the charging interface 21 to maintain an effective electrical connection with the first connecting end 2211 throughout its rotation.

[0039] To facilitate the unscrewing of the charging interface 21 from the mounting hole 112, in this embodiment, the mounting hole 112 is configured as a through hole, allowing the charging interface 21 to be unscrewed through a lateral opening in the mounting hole 112. It is understood that by applying a force to one side of the charging interface 21 through one side opening of the mounting hole 112, the charging interface 21 is forced to unscrew from the other side opening of the mounting hole 112, thereby exposing the charging interface 21 within the mounting chamber 111, facilitating connection between the charging interface 21 and the tablet computer. It is worth noting that the charging interface 21 can be unscrewed from one or both sides of the mounting hole 112.

[0040] Furthermore, to ensure the charging interface 21 is stably housed within the mounting chamber 111, a damping element 24 is provided between the charging interface 21 and the rotating shaft 23. The charging interface 21 is damped during rotation by the damping element 24 and the rotating shaft 23. When the charging interface 21 is screwed into the mounting hole 112, the damping element 24 allows the charging interface 21 to be screwed out of the mounting hole 112 after being subjected to force, preventing the capacitive pen from suddenly screwing out during use and resulting in a poor user experience. In some embodiments, the damping element 24 can achieve the damping effect through the rotating shaft 23 in conjunction with a torsion spring.

[0041] Please see Figure 6 The pen body 1 also includes multiple magnetic attachments 15, which are spaced apart on the mounting bracket 12. The magnetic attachments 15 are used for magnetic connection with the device. The pen body 1 and the device can be connected magnetically, making it easy to carry the capacitive pen and also easy to store it.

[0042] The pen body 1 also includes a display screen 16 and a pen tip. The display screen 16 is fixedly mounted on the mounting bracket 12. The housing 11 is provided with a function display area corresponding to the display screen 16, which is used for function display. The pen tip is used to complete human-computer interaction with the capacitive touch screen. The pen tip is coaxially mounted on one end of the housing 11, and the pen tip is detachably connected to the housing 11. The pen tip can be replaced according to usage needs to meet the diverse usage needs of users.

[0043] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
