[0014] Alternatively, the connector may include an elastic snap-fit ​​structure disposed on the outer casing, which enables the capacitive pen to be detachably snapped into the capacitive pen compartment.

[0015] In some embodiments, the capacitive pen integrates functional components, including one or more of a camera, microphone, pressure sensor, or biometric sensor.

[0016] According to another aspect of the present invention, the present invention further provides a smart host, including the capacitive pen described in any one of the above, and further including:

[0038] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0039] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0040] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] In one embodiment, referring to Figures 1 to 4 of the specification, the capacitive pen provided by this utility model includes: a shell 1, a pen barrel 2, a pen tip 3, and a connector. One end of the shell 1 is provided with a mounting cavity 11, and the other end of the shell 1 is provided with a handheld part 12. The handheld part 12 is used to insert the capacitive pen into the capacitive pen compartment of the smart host, or to remove the capacitive pen from the capacitive pen compartment of the smart host. The pen barrel 2 is adapted to be disposed in the mounting cavity 11, and the pen barrel 2 is a telescopic structure. The pen tip 3 is disposed on the pen barrel 2, and the pen tip 3 is located at the end of the pen barrel 2 away from the handheld part 12, for contacting the capacitive screen and realizing touch or writing functions. The connector is disposed on the shell 1 or the pen barrel 2, and the connector is used to detachably connect the capacitive pen to the smart host.

[0044] In this embodiment, the pen barrel 2 can freely extend and retract within the mounting cavity 11, allowing the capacitive pen to extend during use to conform to ergonomics and shorten during storage to fit small devices (such as smartwatches), significantly improving portability. A detachable connector to the smart host ensures the capacitive pen is securely fixed within the storage compartment, preventing shaking or falling off, while also facilitating one-handed access. By optimizing the overall size and storage form of the capacitive pen, it can be embedded in compact devices such as smartwatches and AR glasses, solving the pain point of traditional capacitive pens being unable to match wearable devices.

[0045] In one embodiment, referring to Figures 1 to 4 of the specification, the pen barrel 2 extends or retracts within the mounting cavity 11 by sliding or rotating to adjust the overall length of the capacitive pen. The retractable connection between the pen barrel 2 and the outer shell 1 is achieved through a segmented nesting structure. The pen barrel 2 employs a two-section nesting structure (similar to a telescope), with the end of the inner rod fixed to the outer shell 1 by a spring pin. When the pen tip 3 is pressed, the spring pin is released, allowing the inner rod to slide freely. After release, it automatically engages at a preset length position. Alternatively, the retractable connection between the pen barrel 2 and the outer shell 1 is achieved through a guide rail slot mechanism. A longitudinal guide rail is provided on the side wall of the pen barrel 2, cooperating with a guide groove within the mounting cavity 11 of the outer shell 1. When the user pushes or pulls the handle 12, the pen barrel 2 slides and extends along the guide rail. A limiting protrusion is provided at the fully extended position to prevent the pen barrel 2 from falling off. Alternatively, the retractable connection between the pen barrel 2 and the outer shell 1 can be achieved through a spiral track structure. The pen barrel 2 is equipped with an oblique spiral groove, and a guide post fixed to the inner wall of the outer shell 1 is embedded in the groove. When the pen barrel 2 is rotated, the spiral groove and the guide post interact, converting the rotational motion into axial displacement, thus achieving stepless length adjustment. The free extension and retraction of the pen barrel 2 within the mounting cavity 11 allows the capacitive pen to extend during use to conform to ergonomics and shorten during storage to fit small devices (such as smartwatches), significantly improving portability.

[0046] Furthermore, the pen barrel 2 is a magnetic pen barrel, with a protrusion 21 at its end and a groove 31 on the pen tip 3. The protrusion 21 is fitted into the groove 31, allowing the pen tip 3 to be magnetically connected to the pen barrel 2 or fixedly connected by adhesive. The pen tip 3 is used to contact the capacitive screen and realize touch or writing functions. The specific structure of the pen tip 3 and how it achieves the above functions can adopt existing technologies, which will not be elaborated here.

[0047] It should be noted that the specific connection structure between the pen barrel 2, the outer shell 1, and the pen tip 3 is described in accordance with the accompanying drawings. In actual use, other structures may be adopted according to actual needs, as long as the above functions can be achieved. This is only for better illustration of the present invention and should not constitute a limitation on the present invention.

[0048] In one embodiment, referring to Figures 1 to 4 of the specification, the connector includes a magnetic adsorption structure, which is disposed on the pen barrel 2 to enable a detachable magnetic connection between the capacitive pen and the capacitive pen compartment; or, the connector includes an elastic snap-fit ​​structure, which is disposed on the outer shell 4 to enable a detachable snap-fit ​​connection between the capacitive pen and the capacitive pen compartment. The magnetic adsorption or elastic snap-fit ​​structure ensures that the capacitive pen is securely fixed within the capacitive pen compartment, preventing shaking or falling off, while also facilitating one-handed access. By optimizing the overall size and storage form of the capacitive pen, it can be embedded in compact devices such as smartwatches and AR glasses, solving the pain point of traditional capacitive pens being unable to match wearable devices.

[0049] Furthermore, the capacitive pen integrates functional components, including one or more of a camera, microphone, pressure sensor, or biometric sensor. For example, an integrated camera enables shooting; an integrated microphone enables recording or voice recording; an integrated pressure sensor enables precise pressure-sensitive input or triggers quick operations based on specific grip pressure; and an integrated biometric sensor combines fingerprints, heart rate, and other biometric features to support identity verification or health data collection. By integrating camera, microphone, and other functional modules, the capacitive pen works in conjunction with the smart host to achieve extended functions such as shooting, recording, and health monitoring, enhancing the device's overall integration.

[0050] According to another aspect of the present invention, referring to Figures 5 to 7 of the specification, the present invention further provides a smart host, including the capacitive pen described in any one of the above, and further including: a housing 4, the housing 4 being provided with a capacitive pen compartment 41, the capacitive pen compartment 41 being located at the end or side of the housing 4, and the capacitive pen being adapted and installed in the capacitive pen compartment 41.

[0051] Specifically, the capacitive pen compartment 41 is located at the end of the housing 4, and the pen tip 3, pen barrel 2, and outer shell 4 are located inside the capacitive pen compartment 41. The handheld part 12 extends out of the capacitive pen compartment 41 by a predetermined length. The specific structure of the handheld part 12 can be a hook-shaped structure, a boss structure, etc.

[0052] Furthermore, a magnetic attachment 42 is provided at the bottom of the capacitive pen compartment 41, and a magnet is provided on the capacitive pen. The capacitive pen is magnetically connected to the magnetic attachment 42 via the magnet. For example, if the pen barrel 2 is a magnetic pen barrel, it is magnetically connected to the magnetic attachment 42 via the magnetic pen barrel. The magnetic attachment 42 can be a magnet or an iron sheet, etc. Alternatively, a spring-loaded fastener is provided on the side of the capacitive pen compartment 41, and the connecting part is a hook that fits the spring-loaded fastener. The spring-loaded fastener and the hook fit together and can be detachably connected, thereby realizing the detachable installation of the capacitive pen.

[0053] It should be noted that the specific installation structure of the capacitive pen is described with reference to the accompanying drawings in the instruction manual. In actual use, other structures may be adopted according to actual needs, as long as the above functions can be achieved. This is only for better illustrating the present invention and should not be construed as a limitation of the present invention.

[0054] Furthermore, the smart host also includes a host body 5, which is set inside the casing 4. The capacitive pen integrates functional components, including one or more of a camera, microphone, pressure sensor, or biometric sensor. The functional components are communicatively connected to the host body 5 to realize image acquisition, voice input, or health monitoring functions.

[0055] In this embodiment, the retractable pen barrel and magnetic connection structure significantly improve the portability and device compatibility of the capacitive pen, making it perfectly compatible with small wearable devices such as smartwatches. The protection mechanism and modular design of the capacitive pen within the smart host enhance the product's durability and expand its intelligent functions such as camera and biometric recognition, further optimizing the human-computer interaction experience and upgrading the capacitive pen from a single input tool into a multifunctional intelligent interactive terminal.

[0056] According to another aspect of this utility model, referring to Figure 8 in the specification, this utility model further provides a wearable device, including the smart host described in any of the above-mentioned claims, and further including: a watch strap 6, the watch strap 6 being connected to both ends of the housing 4. For example, the wearable device can be a smartwatch, a smart bracelet, a medical monitoring wristband, etc. Of course, the wearable device can also be a head-mounted device, a clothing-integrated device, etc. The wearable device of this embodiment, through innovative structural design and functional integration, solves the problems of easy damage to capacitive pens, excessive size, and poor compatibility in the prior art, and expands the interactive and intelligent application scenarios.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0058] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
