Abstract

The invention relates to a sealed type automobile anti-fog instrument. The sealed type automobile anti-fog instrument comprises a bottom plate, a shell body and an upper cover plate, wherein the bottom plate is fixedly connected with the shell body through a first bolt; the shell body comprises a heat conducting net, a graduated disc, an annular lug boss, a sealing ring, an oil sealing ring, a plurality of through holes and a drying cabin; the graduated disc and the sealing ring are mutually clamped; the heat conducting net comprises an annular wall plate, a supporting pillar arranged in the middle of the annular wall plate, a metal net arranged on the supporting pillar and a through hole through which a pointer rotary shaft passes; the upper cover plate comprises a glass panel and a metal ring for fixing the glass panel; the lower end of the upper cover plate and the upper end of the shell body are mutually connected through a second bolt. The sealed type automobile anti-fog instrument provided by the invention has a reasonable structure and has the advantages of high structure strength, good waterproof performance and rapid heat transferring speed; the problem of fogging of an automobile cab instrument is effectively solved.

Description

technical field [0001] The invention relates to the field of automobile cockpit instruments, in particular to a sealed anti-fog instrument for automobiles. Background technique [0002] The known instrument in the cockpit of an automobile is one of the important accessories for grasping the operating condition of the vehicle, and the driver grasps the working condition by means of the display of the instrument during driving. In the case of a large temperature difference between inside and outside, a layer of fog is easily generated on the inner layer of the instrument cover, which affects the visualization effect of the instrument and makes it difficult for the mechanical operator to accurately grasp the operating status of the machine. There are two main reasons for the fogging of the instrument in the cockpit of the car. One is that there is a temperature difference between the inside and outside of the instrument, which makes the water vapor outside the instrument conden...
