Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to a kind of LCD bare screen special-purpose metal cover.
Background technology
Existing automobile instrument liquid crystal display all carries metal frame, by both sides are all wrapped in up and down of liquid crystal display, are provided with a metallic elastic and support, by the static guiding of liquid crystal display out on instrument pcb board. At present, not yet there is the situation using LCD bare screen, it may also be useful to LCD bare screen compares the liquid crystal display with metal frame, decreases integral thickness, has significant advantage; But, LCD bare screen is when carrying out electrostatic and test, it is easy to be damaged by static electricity, it is thus desirable to increase anti-static electricity interference structure.
Practical novel content
The utility model aims to provide a kind of special in the metal cover of LCD bare screen, and protection LCD bare screen also avoids LCD bare screen to be damaged by static electricity when carrying out electrostatic test.
For this reason, the technical scheme that the utility model adopts is: a kind of LCD bare screen special-purpose metal cover, become by steel plate pressing and bending, it is characterized in that: the rectangle frame comprising hollow, rectangle frame is provided with side, four, front, rear, left and right enclose, the front and rear portions of rectangle frame is respectively provided with two locating dowels and crosses hole, and four locating dowels to cross hole in rectangular layout; The left and right side of rectangle frame is respectively provided with two hooks and crosses hole, and four hooks to cross hole in rectangular layout; The middle part of described rear side wall extends vertically downward, the more inside bending of local horizontal, and the left and right portion of rear side wall is respectively provided with a spacing breach of confession.
Preferred as such scheme, described rear side wall extension portion width straight down is less than the width of rectangle frame; The local bending part of rear side wall is partial to the side of rear side wall, and the root of local bending part is provided with the bar v notch v extended up and down. Bar v notch v is technical gaps, facilitates the bending of metal cover.
The beneficial effects of the utility model: special in LCD bare screen, it provides a kind of special cover of metal, decreases overall height; Display screen metal cover is the rectangle ring cover of hollow, hollow part is used for liquid crystal display display, locating dowel crosses hole and spacing breach, for the installation of the liquid crystal support below metal cover and metal cover, again in conjunction with bending part by the static guiding of liquid crystal display on instrument pcb board, avoid LCD bare screen carrying out being damaged by static electricity when electrostatic is tested.
