Abstract
The invention discloses a sliding structure of a rear decorative cover plate of a liquid crystal television, which is arranged on the liquid crystal television with a sound box base and positioned between a small rear shell and the rear decorative cover plate; the rear decorative cover plate is arranged on the back surface of the small rear shell; wherein: under the condition of wall-hung installation, the rear decorative cover plate slides downwards by the thickness of the sound box base to expose the rack screw through hole on the small rear shell; because the rear decorative cover plate adopts a structure capable of sliding downwards, when the loudspeaker box is mounted on a wall, the upright post structure and the screw holes which are used for mounting the loudspeaker box base on the small rear shell are shielded, so that the integral aesthetic feeling that the screw holes do not exist behind the large-size liquid crystal television when the loudspeaker box is erected is considered, and the integral aesthetic feeling that the screw holes do not exist behind the large-size liquid crystal television when the loudspeaker box is mounted on the wall is also considered.
Description
Technical Field
The invention relates to the field of large-size liquid crystal televisions with sound box bases, in particular to a sliding structure of a rear decorative cover plate of a liquid crystal television.
Background
With the popularization and development of large-size liquid crystal televisions (i.e., liquid crystal televisions above 55 inches), consumers can not only pay attention to the integral aesthetic feeling brought to the front of the large-size liquid crystal television by the front decorative panel (or strip), but also pay attention to the integral aesthetic feeling brought to the back of the large-size liquid crystal television by the back decorative cover plate which is invisible or less concerned, and especially, the feeling can be taken into consideration of the installation conditions of standing up the television and hanging on the wall.
The rear shell of a large-size liquid crystal television in the prior art is fixed through screws, under the normal condition, a rear decorative cover plate is installed on a small rear shell (the length and the width of the rear decorative cover plate are much smaller than those of a liquid crystal screen), under the condition of vertical machine installation, any hole groove or rib column structure is not required to be arranged on the rear decorative cover plate, if wall hanging installation is considered, the two conditions can be divided into two conditions, one is that the rear decorative cover plate cannot be detached, the hole groove or rib column required by the wall hanging installation is required to be added on the non-detachable rear decorative cover plate for wall hanging installation, and the other is that the rear decorative cover plate can be detached, and the rear decorative cover plate is detached and can be used for wall hanging installation.
However, in the former case, the rear decorative cover plate with the holes or ribs seriously affects the overall aesthetic feeling behind the large-sized liquid crystal television; in the latter case, not only is the detached rear decorative cover left unused and occupying space, but the small rear housing exposed after detachment still destroys the overall aesthetic appeal behind the large-sized liquid crystal television.
