Abstract

The invention discloses a waterproof and heat insulation type LCD panel of an electric vehicle. The waterproof and heat insulation type LCD panel of the electric vehicle comprises a panel body and an outer housing body which are connected through a clamp; protecting films cover the outer surfaces of the panel body and the outer housing body; the protecting films are prepared from the following components in parts by weight: 1.2 parts of dinonyl-naphthalenesulfonic aci barium salt, 8 to 9 parts of high-chlorinated polyethylene resin, 1.1 parts of 3-chloro-2-hydroxypropyl trimethyl ammonium chloride, 1 to 2 parts of glycol, 2 to 3 parts of sodium perborate, 0.7 part of coal ash, 0.3 part of lauryl sodium sulfate, 1.4 parts of hexyldecanol, and 1 to 2 parts of dodecanedioic acid. According to the waterproof and heat insulation type LCD panel of the electric vehicle, the panel body and the outer housing body re firmly connected; the outer housing body and the inner housing body bring double protection; in addition, the waterproof and damp-proof sealants are arranged at a plurality of positions; in addition, the protecting films cover the outer surfaces of the panel body and the outer housing body, and therefore, a LCD 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 an electric vehicle. Background technique [0002] At present, electric vehicles are often equipped with liquid crystal instruments, and the liquid crystal display in the liquid crystal instrument needs to be controlled by the liquid crystal display control circuit board, and the use environment of electric vehicles is relatively complicated. 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 liquid crystal meter for electric vehicles. The...
