Technical Field

[0001] This utility model relates to the field of liquid crystal instruments, specifically an anti-interference liquid crystal instrument. Background Technology

[0002] LCD instrument panels are digital instruments made using liquid crystal display technology. They display the operating status and basic information of vehicles, aircraft, ships and other means of transportation through electronic screens and have been widely used in many fields such as automobiles, ships, aircraft, industrial automation, energy and power, and machine tool manufacturing.

[0003] To ensure stable operation, existing automotive LCD instrument panels typically have anti-interference features in their casings, effectively blocking external electromagnetic interference signals and preventing electromagnetic signals generated by internal circuits from radiating outwards. However, due to the fixed position of automotive LCD instrument panels, they are easily affected by external light, which may prevent users from seeing the instrument panel content clearly, thus affecting the normal use of the LCD instrument panel. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses an anti-interference type liquid crystal instrument. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5 An anti-interference type LCD instrument includes a housing 1, which is made of stainless steel with a nickel-plated surface, possessing high strength and wear resistance. The nickel plating enhances its shielding effect. An adjustment mechanism 2 is installed in the inner cavity of the housing 1. The adjustment mechanism 2 includes a servo motor 215, which is located in the inner cavity of the housing 1. A first gear 211 is fixedly connected to the output end of the servo motor 215. A second gear 212 is meshed with the surface of the first gear 211. A connecting rod 213 is fixedly connected to the inner cavity of the second gear 212. A fixed seat 214 is rotatably connected to the surface of the connecting rod 213. The surface of the fixed seat 214 is fixedly connected to the inner cavity of the housing 1. A movable seat 206 is rotatably connected to the inner cavity of the fixed seat 214. The inner cavity of the movable seat 206 is fixedly connected to the surface of the connecting rod 213. A display screen 201 is fixedly connected to one side of the movable seat 206. The surface of the display screen 201 is rotatably connected to the inner cavity of the housing 1.

[0018] Reference Figure 2 , Figure 3 and Figure 6An electric push rod 216 is installed in the inner cavity of the housing 1. A connecting frame 204 is fixedly connected to the output end of the electric push rod 216. Two light-shielding plates 202 are fixedly connected to the surface of the connecting frame 204. The electric push rod 216 can push the connecting frame 204 to move. The movement of the connecting frame 204 can drive the two light-shielding plates 202 to move. The two light-shielding plates 202 can block the two sides of the display screen 201, preventing the two sides of the display screen 201 from being interfered with by external light.

[0019] Reference Figure 3 and Figure 4 The inner cavity of the housing 1 is provided with storage slots 209 on both sides. The inner cavity of the storage slot 209 is slidably connected to the surface of the light shield 202. Through the setting of the storage slot 209, the surface of the light shield 202 can be moved into the interior of the housing 1. Thus, when the light shield 202 is not in use, the position of the light shield 202 can be stored, thereby improving the service life of the light shield 202.

[0020] Reference Figure 4 and Figure 4 The inner cavity of the light-shielding plate 202 is provided with a guide groove 205. A guide rod 208 is slidably connected to the inner cavity of the guide groove 205. The surface of the guide rod 208 is fixedly connected to the inner cavity of the storage groove 209. By setting the guide groove 205, the surface of the guide rod 208 can slide inside the light-shielding plate 202. Thus, by setting the guide rod 208, the movement of the light-shielding plate 202 is guided, thereby improving the stability of the light-shielding plate 202 during the movement process.

[0021] Reference Figure 3 and Figure 4 A limiting groove 210 is provided on one side of the inner cavity of the storage slot 209. The inner cavity of the limiting groove 210 is slidably connected to the surface of the connecting frame 204. By setting the limiting groove 210, the surface of the connecting frame 204 can slide inside the housing 1, thereby restricting the movement of the connecting frame 204, preventing the position of the connecting frame 204 from shifting during the movement, and keeping the connecting frame 204 moving horizontally.

[0022] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6A second isolation cover 207 is fixedly connected to the surface of the servo motor 215, and a first isolation cover 203 is fixedly connected to the surface of the electric push rod 216. The second isolation cover 207 and the first isolation cover 203 are made of aluminum alloy, which has high conductivity and electromagnetic shielding performance while being corrosion resistant. The surfaces of the second isolation cover 207 and the first isolation cover 203 are fixedly connected to the inner cavity of the housing 1. The second isolation cover 207 and the first isolation cover 203 isolate the surfaces of the servo motor 215 and the electric push rod 216, thus preventing interference between the servo motor 215 and the electric push rod 216 and the housing 1 during operation.

[0023] Reference Figure 3 and Figure 4 The inner cavity of the housing 1 is provided with a wire hole 4 and a heat dissipation groove 5. A filter screen 3 is fixedly connected to the inner cavity of the heat dissipation groove 5. The wire hole 4 facilitates the connection of external cables into the interior of the housing 1. The heat dissipation groove 5 improves the heat dissipation efficiency inside the housing 1. The filter screen 3 filters the interior of the heat dissipation groove 5 to prevent foreign objects from entering the interior of the housing 1 and affecting the normal use of its internal parts.

[0024] Working principle: When the display screen 201 is affected by external light interference and becomes reflective, the servo motor 215 is started by an external power supply. The servo motor 215 drives the first gear 211 to rotate, which in turn drives the second gear 212 to rotate. The second gear 212 then drives the connecting rod 213 to rotate, which in turn drives the movable seat 206 to rotate. The rotation of the movable seat 206 causes the display screen 201 to rotate inside the housing 1, thereby adjusting the angle of the display screen 201 as needed and reducing the interference of external light. At the same time, the electric push rod 216 is started by an external power supply, which pushes the connecting frame 204 to move. The movement of the connecting frame 204 causes the light shield 202 to move, blocking the sides of the display screen 201 and preventing external light from interfering with the display screen 201, thus further reducing the impact of external light on the display screen 201.

[0025] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
