Description

Chassis and its method of assembly

technical field

The invention relates to a casing and an assembly method thereof.

Background technique

Electronic components such as screens and circuit boards of electronic equipment (such as mobile phones, notebook computers, portable CD players, etc.) are usually housed in casings for protection against moisture, dust, and vibration. Taking the casing of the portable CD player as an example, it includes a main casing, a screen casing, and a pivot connecting the main casing and the screen casing. The main casing is used to place electronic components such as a movement that can record/reproduce information on the disc, and the screen case is used to place electronic components such as a screen that can display information on the disc.

The main casing has an upper plate and a rear side wall extending substantially perpendicularly from a rear side edge of the upper plate. The pivot is an I-shaped structure, which includes a horizontal shaft, a fixed piece and a vertical shaft. The horizontal shaft and the fixed piece are arranged on two ends of the vertical shaft parallel to each other, and the vertical shaft is vertically connected with the horizontal shaft and the fixed piece. The horizontal axis is embedded in the screen shell, and the fixed piece is fixed on the main shell. The screen shell can be rotated around the horizontal axis or the vertical axis, and can be positioned at certain angles so that users can view the screen from different angles.

As we all know, in order to realize the above functions, the pivot needs to meet quite a lot of mechanical and mechanical properties with high requirements. The customer requires proper adjustment, and the customer usually purchases it as a whole piece, and then assembles it into the casing as a whole, and seldom disassembles it. Therefore, in order to assemble the relatively small pivot into the main casing, a part of the rear side wall of the main casing is usually designed to be detachable. When assembling the pivot, first remove this part on the rear side wall, then install the fixed piece and the vertical shaft, and finally reset the removed part. The several seams formed on the rear side wall to meet the pivotal assembly seriously affect the overall appearance of the casing and weaken the strength of the casing.
