Abstract

The invention discloses a liquid crystal instrument for an electric vehicle, wherein a sealant is arranged at multiple positions of the liquid crystal instrument; the sealant comprises the following components in parts by weight: 2-3 parts of argil, 1-2 parts of abietic acid polyoxyethylene ester, 2-3 parts of bisphenol F diglycidyl ether, 17 parts of nitrile rubber, 3-4 parts of fumed silica, 1-2 parts of CTBN modified epoxy resin, 2-3 parts of 2, 2, 4-trimethyl-1, 2-dihydro-quinoline polymer, 1-2 parts of antioxidant 1010, 3-4 parts of vinyl trimethoxy silane and 1-2 parts of fatty alcohol ether sodium sulphate. The liquid crystal instrument for electric vehicle has double protection of inner shell and outer shell, the sealant at multiple parts of the liquid crystal instrument, the long-time waterproof and moisture-proof property of the interior of the outer shell is ensured, particularly, the long-time waterproof and moisture-proof property of inner part of the inner shell is guaranteed, the and long-time waterproof and moisture-proof property of a liquid crystal display control circuit board is guaranteed. The sealant can resist high temperature of 74 DEG C and can resist the low temperature of minus 22 DEG C.

Description

technical field [0001] The invention relates to an electric vehicle liquid crystal meter. 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 object of the present invention is to provide a liquid crystal instrument for electric vehicles, the panel and the outer casing are firmly connected, they will not...
