Abstract

Disclosed in the invention is a novel waterproof thermal-insulation liquid crystal instrument of an electric car. The liquid crystal instrument comprises a panel and an outer shell, wherein the panel and the outer shell are connected by a buckle. Besides, the outer surfaces of the panel and the outer shell are coated with protection membranes; and the protection membrane comprises the following components, by weight: 1.3 parts of heptadecenyl imidazoline alkenyl succinate, 7 to 8 parts of epoxy acrylic resins, 0.7 parts of acetylacetone selenium, 0.4 parts of zinc chloride, 1.1 parts of ultrafine aluminium silicate, 0.7 parts of mica powders, 1 to 2 parts of sodium oleoyl amino fatty acid, 2 to 3 parts of polypropylene glycol, and 1 to 2 parts of triazine polycarboxylic acid compound. According to the novel waterproof thermal-insulation liquid crystal instrument, the panel and the outer shell are connected firmly and the dual protection of the outer shell and the inner shell is realized; and waterproof and moisture-proof sealants are arranged at multiple places and the outer surfaces of the panel and the outer shell are coated with protection membranes, so that the long-term waterproof and moisture-proof effect of the liquid crystal display control circuit board can be guaranteed.

Description

technical field [0001] The invention relates to a liquid crystal meter for a waterproof and heat-insulating 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 new type of waterproof and heat-insulated electric vehicle liquid crystal inst...
