Description

Technical Field

[0001] The utility model relates to a touch panel, in particular to a touch panel with an NFC communication function, belonging to the technical field of notebook computer touch panels. Background Art

[0002] The touchpad is an input device widely used in laptops. It controls the movement of the pointer by sensing the movement of the user's finger. The touchpad can be regarded as a substitute for a mouse. Its working principle is that when the user's finger approaches the touchpad, the capacitance changes, and the touchpad's own control IC will detect the capacitance change and convert it into coordinates. The touchpad uses capacitive sensing to detect the movement of the finger and is not sensitive to the heat of the finger. NFC card reader is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission and exchange between electronic devices.

[0003] At present, laptop computers are small and easy to carry, while the main function of the touchpad is to control the computer, and the function is relatively simple. Therefore, when carrying a laptop computer for travel, the existing touchpad cannot take advantage of the portable feature of the laptop computer to make it have the function of access control or meal card. Therefore, a touchpad with NFC communication function is proposed. Utility Model Content

[0028] In one embodiment, two slots 21 are symmetrically provided on the upper surface of the mounting frame 20, and the inner walls of the two slots 21 are provided with a slide groove 22, the plug plate 12 is slidably connected to the inner wall of the slot 21, the limit plate 17 is slidably connected to the inner wall of the slide groove 22, and the limit plate 17 is slidably connected to the inner wall of the limit groove 13, so that the position of the plug plate 12 can be limited by the slot 21, and the position of the limit plate 17 can be limited by the slide groove 22. When the limit plate 17 is inserted into the limit groove 13, the position of the plug plate 12 is fixed.

[0029] In one embodiment, the guide column 19 is fixedly connected to the side of the inner wall of the slide groove 22 away from the limit plate 17, one end of the spring 18 is fixedly connected to the side of the limit plate 17 away from the plug plate 12, and the other end of the spring 18 is fixedly connected to the side of the slide groove 22 away from the limit plate 17.

At this time, the plug board 12 moves downward and pushes the limiting plate 17 to slide in the slide groove 22. The limiting plate 17 moves along the guide column 19 and squeezes the spring 18. When the plug board 12 moves downward, it drives the limiting slot 13. When the limiting slot 13 moves to a position corresponding to the position of the limiting plate 17, under the push of the spring 18, the limiting plate 17 Insert it into the limit slot 13. At this time, the position of the plug-in board 12 can be limited by the limit plate 17, so that the position of the touch panel 11 is fixed. At this time, the NFC card reader 14 is fixed inside the touch panel. By writing data to the NFC card reader 14, the touch panel as a whole can have the functions of an access card and a meal card. When the touch panel 11 is close to an external reading device, the NFC card reader 14 is triggered.
