Dust cover of vehicle-mounted electronic equipment movement

Abstract

The invention discloses a dust cover of a vehicle-mounted electronic equipment movement. The dust cover structurally comprises a button and a reading box, the rear end of the button is fixedly connected to the front end of the reading box in an embedded mode, a driver starts a vehicle, the vehicle-mounted electronic equipment is powered on, the button is pressed down, a supporting plate drives a scraping device to move outwards, a pressing plate is opened, and an optical disc is placed at the upper end of an erasing plate; a pressing plate is covered, the pressing plate is clamped at the upper ends of the supporting column and the clamping column, the pressing plate fixes an optical disc, an arc plate drives a supporting ring to rotate, the supporting ring drives an erasing block in a sliding rod to rotate, a pressing rod drives supporting rods on the two sides of an arc block to slide on the sliding rod, and erasing corners in erasing strips on the two sides of the supporting rod collide with each other to generate vibration; when the erasing corners collide with each other, the telescopic plate is pushed to abut against the pressing strip and the connecting strip for contraction, vibration generated by collision of the erasing strips is transmitted to the optical disc, dust on the optical disc is shaken off, and the optical disc is prevented from being covered with dust, friction between the optical head and the dust on the optical disc is avoided, and mutual damage between the optical head and the optical disc is avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted electronic equipment, and in particular relates to a dustproof cover for a core of the vehicle-mounted electronic equipment. Background technique [0002] In the car entertainment products, there are CD music players and display players. The CD is placed in the CD music player, and the optical head in the reading column at the upper end of the movement in the CD music player reads the data in the CD. The information is read by friction, so that the audio inside the car will transmit the information to the light head and play it. [0003] Based on the above description, the inventors found that the existing dust cover for the core of a vehicle-mounted electronic device mainly has the following deficiencies. Make the external air flow carry dust into the car and cover the surface of the disc, so that when the disc needs to be used, the disc carries dust into the disc music player, and the r...

Problems solved by technology

[0003] Based on the above description, the inventors found that the existing dust cover for the core of a vehicle-mounted electronic device mainly has the following deficiencies. Make the external air flow carry dust into the car and cover the surface of the disc, so that when the disc needs to be used, the disc carries dust into the disc music player, and the reading column pushes the optical head to squeeze and rub the disc to read the disc information. Then scrape off the dust covered by the optical disc, and fall on the optical head to form a cover, causing the optical head to be covered by dust, and the reading ability is affected, so that the reading column needs to increase the extrusion and friction to read information, so that the optical head is close to the optical disc. Friction damage
