Abstract

Disclosed in the invention is a waterproof and heat insulation type liquid crystal instrument of an electric car. The waterproof and heat insulation type liquid crystal instrument comprises a panel and an outer shell, wherein the panel and the outer shell are connected by a buckle; and the outer surface of the panel and the outer shell are coated with protection membranes. The protection membrane comprises the following components, by weight: 0.7 parts of barium petroleum sulfonate, 7 to 8 parts of allyl heptanoate, 1 to 2 parts of 2-methoxy-4-methylphenol, 2 to 3 parts of propylene glycol, 0.6 parts of stannic oxide, 0.3 parts of kaolin, 1 to 2 parts of nonylphenol ethoxylate carboxylate, 2 to 3 parts of polyvinylpyrrolidone, and 1 to 2 parts of boric acid. According to the waterproof and heat insulation type liquid crystal instrument provided in the invention, the panel and the outer shell are connected firmly and dual protection of the outer shell and the inner shell is realized. Besides, waterproof and moistureproof sealants are arranged at multiple places and the outer surface of the panel and the outer shell are coated with protection membranes, so that the long-term waterproof and moistureproof effects of the liquid crystal display control circuit board can be guaranteed.

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...
