Integral structure of liquid crystal bracket and instrument rear cover

Abstract

The invention discloses an integral structure of a liquid crystal bracket and an instrument rear cover. The integral structure is a rectangular plate body formed by integrally casting and molding an aluminum alloy; a horn installation zone is arranged at the left side of the back surface of the rectangular plate body; a notch through which a connector passes is arranged at the right side of the back surface of the rectangular plate body; the other areas, except for the horn installation zone and the notch, on the back surface of the rectangular plate body are covered with a plurality of cooling fins which extend back and forth; a liquid crystal installation area is arranged on the front surface of the rectangular plate body; the front part, the left part and the right part of the liquid crystal installation area horizontally extend outwards respectively to form a front coaming, a left coaming and the right coaming; the front part, the left part and the right part are crescent; the front coaming is provided with the plurality of cooling fins which extend back and forth; the left coaming and the right coaming are provided with the plurality of cooling fins which extend back and forth; the front end of the front coaming locally and horizontally extends outwards to form two front installation support lugs of an instrument; and the rear end of the liquid crystal installation zone locally and horizontally extends outwards to form two rear installation support lugs of the instrument. The liquid crystal bracket and the instruction rear cover are integrally molded, and have good cooling performance; and dead halt of an all-liquid crystal instrument at a room temperature can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to a rear cover structure used for full liquid crystal instruments. Background technique [0002] Compared with the traditional mechanical instrument, the full liquid crystal instrument has high power and high heat generation. If the ordinary instrument back cover is used, the heat dissipation effect is not good, and the full liquid crystal instrument is prone to crash at room temperature; at the same time, the instrument back cover and the liquid crystal bracket are separated The configuration is made of aluminum alloys, which are separately cast and formed and then installed and fixed together. The structure is complex, the manufacturing cost is high, and the amount of assembly is increased. Contents of the invention [0003] In the present invention, the liquid crystal support and the back cover of the instrument are integrally formed, and the instrument has good...

Problems solved by technology

[0002] Compared with the traditional mechanical instrument, the full liquid crystal instrument has high power and high heat generation. If the ordinary instrument back cover is used, the heat dissipation effect is not good, and the full liquid crystal instrument is prone to crash at room temperature; at the same time, the instrument back cover and the liquid crystal bracket are separated. The setting is made of aluminum alloy and then installed and fixed together after being casted separately. The structure is complex, the manufacturing cost is high, and the amount of assembly is increased.
