Description

Technical Field

[0001] This invention relates to the field of pen-related technology, and in particular to a pen with a data cable. Background Technology

[0002] Data transmission is inseparable from the use of data cables, so in modern society, almost everyone carries a data cable with them for occasional use.

[0003] Chinese Patent Publication No. CN 2018213107123, published on March 1, 2019, discloses a digital pen with a retractable data cable, comprising: a digital pen body with a pen tip at one end and a data cable interface at the other end; a storage box connected to the end of the digital pen body; a scroll housed within the storage box; a data cable wound and stored on the scroll, with one end of the data cable connector inserted into the data cable interface and the other end of the data cable connector extending out of the storage box; and a retraction locking device connected to the scroll to control the extension and retraction of the data cable. While the data cable is well-stored and less likely to be lost, a drawback of this invention is that storing the data cable in the storage box at the end of the digital pen body occupies a significant amount of internal space, making the digital pen body relatively bulky.

[0004] In summary, in existing technologies, data cables are usually not well stored and are easily tangled with other items, which can easily cause damage. To address this, the data cable is stored inside the pen body, but this design causes the data cable to occupy a large amount of internal space in the pen body. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing technologies where the data cable is housed within the pen body, resulting in a large space occupation of the pen body, and provides a pen with a data cable that does not occupy internal space.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pen with a data cable includes a pen body and a data cable. One end of the pen body is provided with a pen tip. The pen body is provided with a grip area located near the end of the pen body with the pen tip and away from the other end of the pen body. The grip area is provided with an arc-shaped locking block that matches the data cable. Both ends of the data cable are fixed with connectors. The connectors are embedded in the pen body and detachably connected to the pen body. The data cable is spirally and evenly wound inside the arc-shaped locking block and detachably connected to the arc-shaped locking block.

[0008] The pen body has a pen tip at one end and a grip area on the pen body. The grip area is located near the end of the pen body with the pen tip and away from the other end. An arc-shaped locking block matching the data cable is located within the grip area. Both ends of the data cable are fixed with connectors, which are embedded into the pen body and detachably connected to it. The data cable is spirally and evenly wound within the arc-shaped locking block and detachably connected to it. Wrapping the data cable within the grip area serves two purposes: firstly, it allows for efficient cable storage and prevents damage; secondly, it replaces the traditional rubber pad, providing cushioning and friction for the fingers when gripping the pen, ensuring comfort and stability; and thirdly, it avoids occupying internal space within the pen body, achieving the goal of space-saving design.

[0009] Preferably, the other end of the pen body is equipped with a battery and a switch button. The battery is located inside the pen body and is detachably connected to it. The data cable is electrically connected to the battery through one of its connectors. The pen body is equipped with a heating pad that covers the surface of the pen body and is detachably connected to it. The heating pad is electrically connected to the battery through the switch button. Connecting the data cable to the battery through one connector and connecting the other connector to an external circuit facilitates battery charging. When the switch button is turned on, the battery powers the heating pad, causing it to generate heat. This provides rapid hand warming in cold weather when the user's hand is in direct contact with the heating pad, preventing hand tremors that could lead to messy handwriting and improving clarity and neatness. Simultaneously, the data cable can be completely detached for data transmission on other devices and other purposes, making it highly practical.

[0010] Preferably, the other end of the pen body is provided with a socket, and several limiting blocks are fixed to the end of the heating pad. These limiting blocks are evenly distributed around the central axis of the pen body and form a circular structure. The limiting blocks contact the other end of the pen body. One of the limiting blocks has a plug-in post that matches the socket. The switch button is located inside the circular structure and on the side of the plug-in post. The heating pad is connected to the socket via the plug-in post and electrically to the battery via the switch button. The limiting blocks help ensure that the heating pad can be installed correctly and that the plug-in post and socket are fully connected, avoiding poor contact that could affect the heating effect of the heating pad. Furthermore, the matching of the heating pad with the socket via the plug-in post improves the strength of the connection between the heating pad and the pen body.

[0011] Preferably, the heating pad is secured with Velcro, and the left and right sides of the heating pad are attached to and detachably connected to the pen body via Velcro. Using Velcro facilitates the installation and removal of the heating pad and helps ensure the flatness of the heating pad surface during use, thus improving writing comfort.

[0012] Preferably, the heating pad comprises a metal wire and two insulating films, wherein one insulating film is fixedly connected to the other to form a sandwich, and the metal wire is laid evenly and meanderingly within the sandwich and fixedly connected to the sandwich. The metal wire is electrically connected to the plug-in post. The heating pad generates heat by energizing the metal wire, and the evenly and meandering arrangement of the metal wire within the sandwich helps to improve the uniformity of heat generation by the heating pad; the insulating films provide protection for the human body and also help to improve writing comfort.

[0013] Preferably, the pen grip area has an annular groove, and the arc-shaped locking blocks are evenly distributed in a spiral shape from top to bottom within the groove and are fixedly connected to the groove. Both ends of the groove have limiting grooves that match the connectors at both ends of the data cable. The ends of the arc-shaped locking blocks correspond to the limiting grooves at both ends of the groove, facilitating the insertion of the connectors at both ends of the data cable into the corresponding limiting grooves. The connectors are inserted into the pen body through the corresponding limiting grooves and are detachably connected to the limiting grooves. One limiting groove is close to the pen tip, and the other limiting groove is away from the pen tip, with a connector on its side wall. The data cable is electrically connected to the battery through its connector matching the connector. The connector is located in the limiting groove away from the pen tip, which facilitates wiring between the connector and the battery, shortens the wiring distance, and helps save costs.

[0014] Preferably, one end of the limiting groove away from the pen tip is connected to the groove. The plug is located inside the side wall of the other end and is connected to the limiting groove. The plug at one end of the data cable is provided with a locking block and a core. One side of the locking block is fixedly connected to the data cable. The core is located on the other side of the locking block and matches the plug. The limiting groove is provided with a pushing block that contacts the locking block. One end of the pushing block is slidably connected to the limiting groove. The other end of the pushing block is provided with a snap-fit ​​groove that matches the data cable. The data cable is located at the bottom of the snap-fit ​​groove. A pull rope is fixed to the open end of the snap-fit ​​groove. The pull rope is located outside the limiting groove. The pushing block is provided with several springs. The springs are located on the side of the locking block. The pushing block is elastically connected to the other end of the limiting groove through the springs. When installing the data cable, first use the pull cord to overcome the force of the spring and push the push block towards the pen tip. Then, insert one end of the data cable into the slot and lock it in place, making the push block contact the locking block. Release the pull cord, and the spring, through the push block, acts on the locking block, causing the connector to move away from the pen tip. This allows the core on the connector to insert into the interface, establishing an electrical connection with the battery. Finally, insert the data cable into the spiral-shaped arc-shaped locking block. The operation is convenient and quick. The pull cord helps the heating pad to tightly wrap around the pen body, ensuring the flatness of the heating pad surface, improving writing comfort, and enhancing the overall aesthetics. It also prevents damage to the heating pad, extending its service life.

[0015] Preferably, a slide rail matching one end of the push block is fixed inside the limiting groove. The slide rail is parallel to the pen body, and the push block is slidably connected to the limiting groove via the slide rail. This design ensures that the push block always slides vertically, which helps to ensure that the connector can be accurately inserted into the connector under the action of the spring.

[0016] Preferably, one end of the limiting groove near the pen tip is connected to the groove, and the other end is provided with a sliding groove. A limiting plate is provided in the sliding groove, and the limiting plate is slidably connected to the sliding groove. The connector at the other end of the data cable is located on one side of the limiting plate and in the limiting groove. A pull rope is fixed on the opposite side of the limiting plate. The pull rope is located at one end of the limiting plate and outside the limiting groove. The sliding groove is connected to the limiting groove through an open end. A spring is provided at the bottom of the sliding groove, and the other end of the limiting plate is elastically connected to the sliding groove through the spring. Before inserting the connector at the other end of the data cable into the limiting groove, use the second pull cord to overcome the force of the second spring and pull the limiting plate towards one end of the pen tip, so that the limiting groove is fully exposed, facilitating the installation of the connector. Then release the second pull cord, and the limiting plate moves away from the pen tip under the reset action of the second spring, so that the connector is well limited, which helps to protect the connector. In summary, the heating pad can cover the upper half of the pen body or the entire pen body. Therefore, the connectors at both ends of the data cable are respectively inserted into the corresponding limiting grooves, and the design of the first and second pull cords helps the heating pad to cover the entire pen body well. In this case, the diameter of the data cable should be less than or equal to the depth of the groove, preferably the same as the depth of the groove, to prevent the deformation of the heating pad and ensure the flatness of the heating pad.

[0017] Preferably, the cross-sectional shape of the data cable is circular, and the central angle corresponding to the cross-section of the arc-shaped locking block is greater than 180 degrees, which facilitates locking the data cable and makes the data cable installed firmly. The bottom of the arc-shaped locking block is fixedly connected to the groove, and the opening end of the arc-shaped locking block is shaped like a trumpet, which plays a guiding role in the installation of the data cable, making the installation convenient and quick.

[0018] The beneficial effects of this invention are: it allows for efficient storage of the data cable, preventing damage; it ensures comfort and stability when holding the pen; it avoids occupying the internal space of the pen body; it facilitates battery charging; in cold weather, it allows the user's hand to warm up quickly after direct contact with the heating pad, preventing hand tremors and resulting in messy handwriting, thus improving clarity and neatness; the data cable can also be completely detached for data transmission and other uses on other devices, making it highly practical; it ensures the heating pad is properly installed; it avoids poor contact that could affect the heating effect of the heating pad; it improves the firmness of the connection between the heating pad and the pen body; it facilitates the installation and removal of the heating pad; it ensures the flatness of the heating pad surface during use; it helps improve the uniformity of heat generation from the heating pad; it shortens the wiring distance, saving costs; it is convenient and quick to operate; it improves the overall aesthetics while minimizing damage to the heating pad and extending its service life; it ensures the connector is accurately inserted into the interface under the action of the spring; it protects the connector; it ensures a secure data cable installation; and it is convenient and quick to install.
