Problems solved by technology

[0002] At present, motorcycles are often equipped with LCD instruments. The LCD screen in the LCD instrument needs to be controlled by the LCD control circuit board. However, the motorcycle is used in a more complicated environment. For example, it is sometimes used in rainy days. The liquid crystal display control circuit board is damp, and the liquid crystal display control circuit board is damp, which will affect the normal display of the liquid crystal display, causing users to be unable to effectively control the use status of the battery car

Abstract

The invention discloses a waterproof and heat insulation type liquid crystal display panel of a motorcycle. The waterproof and heat insulation type liquid crystal display panel of the motorcycle comprises a panel body and an outer housing which are connected through a clamp; protecting films are coated on the outer surfaces of the panel body and the outer housing; the protecting films are prepared from the following components in parts by weight: 1 to 2 parts of petroleum sodium sulfonate, 6 to 7 parts of isocyanate ethyl methacrylate, 1 to 2 parts of ethanediol, 0.9 part of styrene-acrylic emulsion, 1.2 parts of magnesium carbonate, 0.2 part of slaked lime, 1 to 2 parts of polyalkoxylated carboxylate, 2 to 3 parts of hydroxy propyl methyl cellulose, and 1 to 2 parts of tert-Butylbenzoic acid. According to the waterproof and heat insulation type liquid crystal display pane of the motorcycle, the panel body and the outer housing are firmly connected; the outer housing and an inner housing perform double protection; waterproof and damp-proof sealants are arranged at a plurality of positions, and the protecting films are coated on the outer surfaces of the panel body and the outer housing, so that a liquid crystal display control circuit board can be resistant to water and damp for a long term.

Description

technical field [0001] The invention relates to a waterproof and heat-insulating liquid crystal meter for motorcycles. Background technique [0002] At present, motorcycles are often equipped with LCD instruments. The LCD screen in the LCD instrument needs to be controlled by the LCD control circuit board. However, the motorcycle is used in a more complicated environment. For example, it is sometimes used in rainy days. The liquid crystal display control circuit board is damp, and the liquid crystal display control circuit board will affect the normal display of the liquid crystal display when the liquid crystal display control circuit board is wet, causing the user to be unable to effectively control the use status of the battery car. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof and heat-insulated motorcycle liquid crystal instrument, the panel and the outer casing are firmly connected, and will not be separated from e...
