Description

Technical Field

[0001] This utility model relates to the field of human-computer interaction technology, and in particular to a charging structure for an infrared touch device. Background Technology

[0002] Existing electrical connection technologies between computers and infrared touch devices employ physical plug-and-play interfaces, such as USB, Type-C, or Android interfaces. However, these connection methods are relatively cumbersome. Users need to precisely align the connector, and when using USB or Android interfaces, they also need to distinguish the front and back to successfully connect the infrared touch device to the computer. This process is even more difficult in low-light or limited operating space environments, requiring the user to repeatedly bump the charging connector against the interface to deduce the interface's position before accurate insertion.

[0003] However, frequent collisions can easily wear down the interface shell, and may cause the interface to become loose, bent, worn, or even damaged internal contacts. Under slight shaking or external force, poor contact may occur at the connection point, resulting in signal transmission interruption or instability, thus affecting the normal use of the infrared touch device. Utility Model Content

[0004] The main purpose of this invention is to propose a charging structure for an infrared touch device, aiming to provide a convenient electrical connection structure that can stably connect to the infrared touch device.

[0005] To achieve the above objectives, the present invention proposes a charging structure for an infrared touch control device, comprising:

[0006] A face mask frame is installed on the edge of the computer's display area. An infrared touch component is provided inside the face mask frame. The infrared touch component is electrically connected to a magnetic female connector. An electrical connection port is provided on the face mask frame, and the magnetic female connector is exposed at the electrical connection port.

[0007] A charging connector includes a magnetic male connector, which is magnetically connected to the magnetic female connector.

[0008] In one embodiment, the magnetic female connector includes at least two female magnetic elements, and the external magnetic poles of the at least two female magnetic elements are different; the magnetic male connector includes at least two male magnetic elements, and the male magnetic elements are arranged in a one-to-one correspondence with the female magnetic elements, and the external magnetic poles of the male magnetic elements are configured differently from the external magnetic poles of the corresponding female magnetic elements.

[0009] In one embodiment, two female magnetic components are provided, respectively located near the opposite ends of the magnetic female base. The magnetic female base also includes multiple female conductive terminals, which are located near the center of the magnetic female base. The magnetic male base also includes multiple male conductive terminals, which are arranged in a one-to-one correspondence with the female conductive terminals.

[0010] In one embodiment, a guide groove is provided at the electrical connection port, the display end face of the magnetic female is placed on the bottom wall of the guide groove, the female magnetic component and the female conductive terminal are both provided on the display end face, the charging connector is provided with a guide protrusion corresponding to the guide groove, and the magnetic male is exposed on the top surface of the guide protrusion.

[0011] In one embodiment, the mask frame further includes a convex bulge disposed on the side of the mask frame away from the computer in the thickness direction to accommodate the magnetic female connector.

[0012] In one embodiment, the cross-sectional shape of the convex hull is one of a trapezoid, a rectangle, or a semicircle;

[0013] In one embodiment, the convex bulge and the mask frame are integrally molded parts.

[0014] In one embodiment, two male magnetic components are provided, respectively located near the opposite ends of the magnetic male base.

[0015] In one embodiment, the charging connector has a mounting surface shell that exposes the magnetic male seat and a connection end face that connects to a wire, the connection end face being disposed adjacent to the mounting surface shell.

[0016] In one embodiment, the end of the wire away from the connection end face is connected to a data connector.

[0017] In one embodiment, the outer peripheral surface of the mask frame includes a side shell surface extending along the thickness direction of the mask frame, the electrical connection port is disposed on the side shell surface, and both the electrical connection port and the magnetic ferrule extend in a direction intersecting the thickness direction of the mask frame.

[0018] In one embodiment, the thickness of the mask frame ranges from 4 mm to 6 mm.

[0019] In one embodiment, the thickness of the magnetic ferrule ranges from 3 mm to 4 mm.

[0020] In one embodiment, the length of the magnetic female base ranges from 12 mm to 16 mm.

[0021] In one embodiment, the charging connector includes a mounting shell for mounting the magnetic male seat, the thickness of which ranges from 6 mm to 9 mm.

[0022] In one embodiment, the length of the charging connector ranges from 17 mm to 22 mm.

[0023] This invention simplifies the electrical connection between the infrared touch device and the computer by magnetically connecting the charging connector to the electrical interface on the faceplate frame. Users no longer need to precisely align the interface; simply placing the charging connector near the infrared touch device's electrical interface allows for automatic magnetic attraction and connection. This significantly saves users time and effort in connecting the device, improving ease of use. Compared to traditional plug-and-play connections, the magnetic connection reduces the risk of damage to the electrical interface due to repeated collisions and plugging / unplugging, effectively preventing issues such as loosening, damage, or poor contact of the magnetic female connector. Specifically, the magnetic female connector provides electrical and data transmission to the infrared touch components, enabling interaction between the infrared touch device and the computer. Therefore, the magnetic charging method also contributes to a stable connection between the electrical interface and the charging connector, improving the stability of electrical and data transmission for a stable connection and use between the infrared touch device and the computer.

[0038] This utility model proposes a charging structure for an infrared touch control device.

[0039] Please see Figures 1 to 6 In one embodiment of this utility model, the charging structure of the infrared touch device includes:

[0040] The face mask frame 100 is a frame that can be installed on the edge of the computer's display area. The face mask frame 100 is equipped with an infrared touch component, which is electrically connected to the magnetic female connector 12. The face mask frame 100 is equipped with an electrical connection port 11, and the magnetic female connector 12 is exposed in the electrical connection port 11.

[0041] The charging connector 200 includes a magnetic male connector 21, which is magnetically connected to a magnetic female connector 12.

[0042] The technical solution of this utility model simplifies the electrical connection between the infrared touch device and the computer by magnetically connecting the charging connector 200 to the electrical connection port 11 on the faceplate frame 100. Users do not need to precisely align the interface; they only need to bring the charging connector 200 close to the electrical interface of the infrared touch device, and they will automatically attract and connect under magnetic force. This greatly saves users time and effort in connecting the device and improves the convenience of using the device. Furthermore, compared with traditional plug-in connections, the magnetic connection reduces the risk of damage to the electrical connection port 11 due to repeated collisions and plugging / unplugging, effectively preventing problems such as loosening, damage, or poor contact of the magnetic female connector 12. In particular, the magnetic female connector 12 can be used to provide electrical and data transmission to the infrared touch components, enabling the infrared touch device to interact with the computer. Therefore, the magnetic charging method also helps to ensure a stable connection between the electrical connection port 11 and the charging connector 200, thereby improving the stability of electrical and data transmission, allowing the infrared touch device to be stably connected and used with the computer.

[0043] In one embodiment, the magnetic female connector 12 includes at least two female magnetic elements 121, and the external magnetic poles of the at least two female magnetic elements 121 are different; the magnetic male connector 21 includes at least two male magnetic elements 211, which are arranged one-to-one with the female magnetic elements 121, and the external magnetic poles of the male magnetic elements 211 are configured differently from the external magnetic poles of the corresponding female magnetic elements 121. The female magnetic elements 121 and male magnetic elements 211 that attract each other on the magnetic female connector 12 and the magnetic male connector 21 adopt an "opposite magnetic pole correspondence" design (e.g., the female end is the N pole, and the corresponding male end is the S pole). The attraction between the magnetic poles maximizes the attraction strength, ensuring a tight connection and preventing detachment due to external forces (such as vibration or tilting). The difference in polarity of the magnetic poles forms a natural direction identification mark. When the male connector approaches the female connector, it automatically adjusts to the correct position due to the attraction of opposite magnetic poles, achieving precise "blind insertion" and reducing manual adjustment steps. Specifically, if a user attempts to connect the male connector in the wrong orientation (e.g., the polarity of the male magnetic component 211 is the same as that of the female connector), the repulsive force between the like magnetic poles will be directly fed back to the user, preventing incorrect insertion and avoiding interface damage or short circuit problems caused by reverse connection. In other embodiments, the external magnetic poles of the female magnetic component 121 may all be the same.

[0044] In one embodiment, two female magnetic components 121 are provided, respectively disposed near opposite ends of the magnetic female base 12. The magnetic female base 12 also includes a plurality of female conductive terminals 122, which are disposed near the center of the magnetic female base 12. The magnetic male base 21 also includes a plurality of male conductive terminals 212, which are disposed one-to-one with the female conductive terminals 122. Further, at least two female conductive terminals 122 are connected to an electrical transmission component, and at least two female conductive terminals 122 are connected to a data transmission component. That is, there are at least four male conductive terminals 212 and four female conductive terminals 122 between the magnetic male base 21 and the magnetic female base 12. The four male conductive terminals 212 are spaced apart along the extension direction of the magnetic male base 21, and the four female conductive terminals 122 are spaced apart along the extension direction of the magnetic female base 12. Specifically, the female missile terminal is configured as a conductive electrode plate 123, and the male conductive terminal 212 is configured as a conductive projectile pin 213. In charging structures with multiple conductive circuits, polarity differences can help distinguish functional modules, ensuring correct contact between contacts of different signal channels and avoiding signal crosstalk. In other embodiments, the female magnetic component 121 may be located in the middle of the magnetic socket, and the female conductive terminals 122 may be located at both ends of the magnetic socket.

[0045] In one embodiment, a guide groove 14 is provided at the electrical connection port 11. The display end face 124 of the magnetic female connector 12 is placed on the bottom wall of the guide groove 14. The female magnetic component 121 and the female conductive terminal 122 are both provided on the display end face 124. The charging connector 200 is provided with a guide protrusion 22 corresponding to the guide groove 14, and the magnetic male connector 21 is exposed on the top surface of the guide protrusion 22. When the magnetic male connector 21 and the magnetic female connector 12 are magnetically connected, the guide protrusion 22 is inserted into the guide groove 14. At this time, the magnetic male connector 21 and the magnetic female connector 12 are strictly restricted to contact at a preset angle, reducing poor contact caused by lateral displacement due to vibration. This is especially suitable for high-frequency signal transmission or high-current scenarios (such as fast charging and high-speed data interfaces), ensuring the reliability of the electrical connection. It can also reduce the risk of dust and liquid directly intruding into the connection between the charging connector 200 and the electrical connection port 11. In other embodiments, the conductive groove may not be provided.

[0046] In one embodiment, the mask frame 100 further includes a protrusion 15, which is located on the side of the mask frame 100 away from the computer in the thickness direction. This protrusion 15 increases the space within the mask frame 100 to accommodate electrical transmission components and data transmission components. Further, the cross-sectional shape of the protrusion 15 can be trapezoidal, rectangular, or semi-circular, and is not limited thereto. The protrusion 15 is connected to the mask frame 100, and the connection method includes, but is not limited to, integral molding, splicing, and bonding. When the protrusion 15 and the mask frame 100 are integrally molded, the mask frame 100 and the protrusion 15 are manufactured using integral molding technology, which helps to reduce the number of parts and assembly steps, lower costs, improve the overall stability of the mask frame 100, and, to a certain extent, make the surface of the mask frame 100 smoother, reduce seams and defects, and improve the aesthetics of the mask frame 100.

[0047] In one embodiment, the charging connector 200 has a mounting shell 23 that exposes the magnetic male connector 21, and a connection end face 24 for connecting to the wire 25. The connection end face 24 is disposed adjacent to the mounting shell 23. The adjacent placement of the connection end face 24 and the mounting shell 23 of the charging connector 200 allows the connection point of the wire 25 to be close to the magnetic male connector 21, reducing redundant space required for internal wiring. This layout helps to reduce the volume of the charging connector 200 and achieve a high-density integrated design. In other embodiments, the connection end face 24 may be disposed opposite to the mounting shell 23.

[0048] In one embodiment, the end of the wire 25 furthest from the connection face 24 is connected to the data connector 26. The data connector 26 can be a USB connector, a Type-C connector, or an Android connector. The data connector 26 connects to the computer's interface, and the charging connector 200 connects to the infrared touch device, enabling power supply to the infrared touch device while simultaneously transmitting signals between the computer and the infrared touch device. In other embodiments, the end of the wire 25 furthest from the connection face 24 can be directly electrically connected to the computer's output terminal.

[0049] In one embodiment, the outer peripheral surface of the mask frame 100 includes a side shell surface 13 extending along the thickness direction of the mask frame 100. An electrical connection port 11 is disposed on the side shell surface 13. Both the electrical connection port 11 and the magnetic connector 12 extend in a direction intersecting the thickness direction of the mask frame 100. That is, the side shell surface 13 of the mask frame 100 extends along the thickness direction, allowing the electrical connection port 11 and the magnetic connector 12 to be integrated into the side of the device, rather than occupying the front display area or the rear structural space. This optimizes the utilization of internal space and facilitates a thinner and lighter design for the device. The extension of the electrical connection port 11 and the magnetic connector 12 in a direction intersecting the thickness direction ensures that the adsorption direction of the charging connector 200 is parallel to the mounting surface of the infrared touch device, guaranteeing effective transmission of the magnetic force. Furthermore, the side-mounted interface allows users to perform blind insertion when attaching the charging connector 200 to the infrared touch device, completing the connection without adjusting the device angle. Utilizing the magnetic self-alignment characteristic, it achieves a convenient "one-touch" connection, reducing user operational complexity. In other embodiments, the electrical connection interface may be located on the side of the face mask frame 100 away from the computer.

[0050] In one embodiment, the thickness of the face mask frame 100 ranges from 4 mm to 6 mm, the thickness of the magnetic female connector 12 ranges from 3 mm to 4 mm, and the length of the magnetic female connector 12 ranges from 12 mm to 16 mm. The magnetic male connector 21 corresponds to the magnetic female connector 12, that is, the thickness of the magnetic male connector 21 ranges from 3 mm to 4 mm, and the length of the magnetic male connector 21 ranges from 12 mm to 16 mm. Within the above range, it is possible to electrically connect the face mask frame 100 to the charging connector 200 while keeping the face mask frame 100 relatively thin, thereby achieving a slimmer and lighter infrared touch device. Further, the charging connector 200 includes a mounting shell 23 for mounting the magnetic male connector 21. The thickness of the mounting shell 23 ranges from 6 mm to 9 mm, and the length of the charging connector 200 ranges from 17 mm to 22 mm. That is, within the above-mentioned range, the charging connector 200 can be adapted to connect with the magnetic female connector 12 while completing the protective wrapping of the magnetic male connector 21, so that the charging connector 200 can be miniaturized to adapt to the thin and light infrared touch device.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
