Description

Technical Field

[0001] This application relates to a capacitive touchscreen with heating function. Background Technology

[0002] A capacitive touchscreen is a four-layer composite glass screen, with an ITO (indium tin oxide) coating on both the inner surface and the interlayer. When a user touches the screen, the human body's electric field creates a coupling capacitor between the user's finger and the touchscreen. Because a high-frequency signal is applied to the touchscreen, the finger absorbs a small current. This current flows out from electrodes at the four corners of the screen, and theoretically, the current flowing through the four electrodes is proportional to the distance from the finger to the corner. The controller calculates the position information by precisely measuring the ratio of these four currents.

[0003] The existing patent document "CN219574789U Capacitive Touch Screen" discloses a capacitive touch screen. Although this capacitive touch screen can be used, when used in extreme low temperature environments, the low temperature causes changes in the physical and chemical properties of the touch screen, making the touch less sensitive. Also, when the screen is in contact with the human body at a low temperature, the human body temperature is high and condensation is likely to occur on the screen surface.

[0004] In other words, existing technologies have the following technical problems: ordinary capacitive touchscreens become less sensitive in extreme low-temperature environments and are prone to condensation on the screen surface. Therefore, a capacitive touchscreen with a heating function is proposed to address these issues. Summary of the Invention

[0036] Please see Figure 1-5As shown, a capacitive touchscreen with heating function includes:

[0037] A capacitive touchscreen 2 is fixedly connected to a rectangular protective base 1.

[0038] Heating component 4 is fixedly installed in the inner cavity of rectangular protective base 1. Heating component 4 is in contact with capacitive touch screen 2 and can heat capacitive touch screen 2.

[0039] A surface cleaning component 3 is installed on the side of the rectangular protective base 1, and the surface cleaning component 3 can move on the surface of the capacitive touch screen 2.

[0040] To address the problem that ordinary capacitive touchscreens 2 become less sensitive in low-temperature extreme environments due to changes in their physical and chemical properties, this application designs a heating component 4. This component 4 heats the capacitive touchscreen 2, preventing sensitivity loss due to excessively low temperatures. Furthermore, to address the issue that ordinary touchscreens are prone to condensation when in contact with warm human bodies in low-temperature environments, a surface cleaning component 3 is designed. This component 3 automatically moves across the surface of the capacitive touchscreen 2 to absorb and clean the condensation.

[0041] The capacitive touch screen 2 includes a screen panel 201, a fixing ear plate 202 and a mounting hole 203. The fixing ear plate 202 is fixedly provided on both sides of the screen panel 201.

[0042] The fixed ear plate 202 has mounting holes 203, which are fixedly connected to the rectangular protective base 1 by bolts. The heating component 4 includes a heat-conducting plate 401 and a heating resistance wire 402. The heat-conducting plate 401 is fixedly disposed on the bottom wall of the inner cavity of the rectangular protective base 1. The heat-conducting plate 401 is made of alumina ceramic material and is thin. The heat-conducting plate 401 is in contact with the surface of the capacitive touch screen 2. The heating resistance wire 402 is embedded and fixedly disposed inside the heat-conducting plate 401 and is curved. Through this technical solution, the heating resistance wire 402 can generate heat, which is then further conducted to the capacitive touch screen 2 through the heat-conducting plate 401, thereby achieving the heating effect on the capacitive touch screen 2 and avoiding the problem of reduced sensitivity caused by excessively low temperature environments.

[0043] The surface cleaning component 3 includes a movable foot 301, a rotating shaft 302, a rotating roller 303, a water-absorbing sponge roller 304, a movable slider 305, and a micro servo motor 307. The rectangular protective base 1 is provided with a guide groove 101 inside. The movable foot 301 is located at the upper edge of the guide groove 101 and slides with the guide groove 101.

[0044] The movable slider 305 is disposed at the guide groove 101 and slides in cooperation with the guide groove 101. The movable slider 305 is fixedly connected to the movable stand 301. Through this technical solution, the movable slider 305 can move the movable stand 301.

[0045] A micro servo motor 307 is fixedly installed at the guide slide 101. One end of a threaded rod 306 is fixedly connected to the end of the output shaft of the micro servo motor 307. The other end of the threaded rod 306 extends to the side wall of the guide slide 101 and slides with the guide slide 101. The threaded rod 306 passes through the movable slider 305 and is threaded with the movable slider 305.

[0046] A rotating shaft 302 is rotatably connected to the side wall of the movable stand 301. A rotating roller 303 is fixedly connected to the arc-shaped wall of the rotating shaft 302. A water-absorbing sponge roller 304 is fixedly installed on the arc-shaped surface of the rotating roller 303. The water-absorbing sponge roller 304 contacts the surface of the capacitive touch screen 2. Through this technical solution, the operation of the micro servo motor 307 can drive the threaded rod 306 to rotate. The rotation of the threaded rod 306 can drive the movable slider 305 to move. In turn, the movement of the movable slider 305 can drive the movable stand 301 to move. This causes the water-absorbing sponge roller 304 to roll on the surface of the capacitive touch screen 2. The rolling movement of the water-absorbing sponge roller 304 absorbs and cleans the condensation remaining on the surface of the capacitive touch screen 2, avoiding the problem of condensation affecting touch operation and achieving the beneficial effect of automatic cleaning.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
