Abstract

A hinged liquid crystal display capable of increasing rotary angle comprises a base, a rotating device and a liquid crystal panel, wherein the rotating device is arranged on the base in and can rotate between a first and a second positions; the liquid crystal panel is rotatablely connected with the base through the rotating device. When the rotating device is positioned at the first position, the liquid crystal panel is perpendicular to the base; while the rotating device is positioned at the second position, the liquid crystal panel is parallel to the base. Because the liquid crystal panel can rotate 90 degrees relative to the base, the utility model can be arranged on wall without take down the bottom board.

Description

Has the hinge type LCD that the anglec of rotation is increased

The relevant a kind of LCD of the utility model, particularly relevant a kind of hinge type LCD that the anglec of rotation is increased that has.

PC has become the essential articles for use of daily life, and along with the progress of material skill and consumer's hobby, compact LCD more has the trend that day by day replaces traditional type iconoscope screen.

Because LCD is compact, therefore except furnishing it on table, also with the function of wall hanging.

Fig. 1 shows an existing LCD 10, and it comprises a liquid crystal panel 11 and a base 12, and LCD 10 is placed on the desk 20 by base 12; When desire is installed on LCD 10 on the wall, need earlier base 12 to be separated with liquid crystal panel 11, and then a not shown wall hanging is arranged at the back side of liquid crystal panel 11 with assembled component, just the LCD 10 that removes behind the base 12 can be installed on the wall at last.With base 12 and the operation that liquid crystal panel 11 separates, for the user, bother very much, and in the process of dismounting, often cause the loss and the damage of part, more add user's puzzlement.

In addition, because the base of existing LCD only is fit in order to being positioned on the table, so the anglec of rotation between liquid crystal panel and base has certain restriction;

In addition,, and make the required space of packing increase owing to this angle limits makes that the size of LCD has a least limit when existing LCD is packed, and feasible cost raising of transporting.

Principal feature with the hinge type LCD 30 that can make anglec of rotation increase of the present utility model is: in the whirligig 32 of LCD 30, add a hinge 321 that the anglec of rotation is increased, therefore following first referenced in schematic illustrates hinge 321 of the present utility model.

With reference to figure 2a, 2b, 2c, 2d and 2e, hinge 321 comprises one first substrate 3211, one second substrate 3212, one first rotating shaft 3213, one second rotating shaft 3214, a block piece 3215, a pivot arm 3216 and a spring 3217; Wherein first substrate 3211 is fixed on the base 31 described later, and has one first perforation, 32111 and one breach 32112, and one first terminal A and one second terminal B are arranged respectively on breach 32112; Second substrate 3212 is fixed on the base 31, and first rotating shaft 3213 is arranged in first substrate 3211 in a movable manner, and second rotating shaft 3214 is arranged in second substrate 3212.

Block piece 3215 is arranged in first rotating shaft 3213 in a movable manner, and wherein when base 31 during with liquid crystal panel 33 described later vertical (is primary importance to call this in the following text), block piece 3215 passes first perforation, 32111 (shown in Fig. 2 a).Pivot arm 3216 rotatably is arranged in first rotating shaft 3213 and second rotating shaft 3214, in order to support liquid crystal panel 33 (shown in Fig. 4 a), and has a block 32161; Spring 3217 is arranged in first rotating shaft 3213, wherein when base 31 during with liquid crystal panel 33 parallel (is the second place to call this in the following text) spring 3217 be in compressive state (shown in Fig. 2 d).

The function of hinge 321 and mode of operation will illustrate the array mode of hinge 321 and other members in the explanation together of other diagrams of following cooperation below with reference to Fig. 3.

Fig. 3 is the three-dimensional exploded view of display rotary device 32 and base 31, whirligig 32 comprises an above-mentioned hinge 321 and a housing department 322, wherein hinge 321 as above-mentioned be to be used to connect base 31 and liquid crystal panel 33, and housing department 322 is in order to coat hinge 321, and it is made of one first shell 3221, one second shell 3222 and one the 3rd shell 3223.

Base 31 is made of a base body 311, one first joint portion 312 and one second joint portion 313.

Constitute below with reference to Fig. 4 a, the 4b explanation integral body with the hinge type LCD 30 that can make anglec of rotation increase of the present utility model, LCD 30 comprises above-mentioned base 31, above-mentioned whirligig 32 and a liquid crystal panel 33.Wherein base 31 can be placed on the table, and whirligig 32 is arranged on the base 31 in the mode that can rotate between a primary importance (shown in Fig. 4 a) and a second place (shown in Fig. 4 b); Liquid crystal panel 33 rotatably is connected with base 31 by whirligig 32, when whirligig 32 is positioned at primary importance shown in Fig. 4 a, liquid crystal panel 33 is vertical with base 31, this moment, LCD 30 can be placed on the table, and when whirligig 32 is positioned at the second place shown in Fig. 4 b, liquid crystal panel 33 is parallel with base 31, and this moment, LCD 30 can and be installed on the wall by the combination of the installation component on preformed hole that is arranged at liquid crystal panel 33 rears (not shown) and the wall.

The formation of LCD 30 of the present utility model below illustrates its mode of operation as mentioned above.

When desire is positioned over LCD 30 when last, liquid crystal panel 33 is positioned at the primary importance shown in Fig. 4 a, and it is vertical with base 31, support the first terminal A butt (shown in Fig. 2 b) of breach 32112 of block 32161 and first substrate 3211 of the pivot arm 3216 of liquid crystal panel 33 this moment, and block piece 3215 passes first of first substrate 3211 and bores a hole 82111.

When LCD 30 is positioned over when last, it also can be by layback 25 degree shown in Fig. 2 c.

When desire is installed on LCD 30 on the wall, the user can be shown in Fig. 2 d like that, first rotating shaft 3213 is pushed away to the right, this moment, spring 3217 was compressed, block piece 3215 separates with the first perforation 32i11 of first substrate 3211, and can make pivot arm 3216 rotations of supporting liquid crystal panel 33, the second terminal B butt (shown in Fig. 2 e) up to the breach 32112 of the block 32161 of pivot arm 3216 and first substrate 3211, this moment, liquid crystal panel 33 was positioned at the second place shown in Fig. 4 b, parallel with base 31, and LCD 30 can be installed on the wall; Because mode and prior art that LCD 30 is installed on the wall are similar, therefore omit its explanation at this, but Ying Wangyi's is that LCD 30 of the present utility model is on being suspended in wall the time, do not need base is separated with LCD earlier, but the LCD with base directly can be installed on the wall.

As mentioned above, by hinge of the present utility model rotation angle range between liquid crystal panel and base plate is increased, not only when being positioned over LCD on the table, liquid crystal panel can be limited in the set scope, simultaneously when hanging on LCD on the wall, also can with liquid crystal panel rotation as for base parallel and convenient the suspension, and then save the puzzlement that needs the base dismounting.

In addition, LCD of the present utility model can be put formula with wall-hanging and platform, not only can directly be positioned on the table, in the time of simultaneously on hanging on wall, do not need base is separated with LCD earlier yet, but the LCD with base can be installed on the wall.

Therefore in addition, because that liquid crystal panel of the present utility model can rotate in base is parallel, when packing the space is more reduced, and landed cost is reduced, also can reduce the volume of timber simultaneously, the result makes product of the present utility model more meet the demand of environmental protection.

Though the utility model is disclosed with preferred embodiment; but this embodiment is not in order to limit the utility model; any person skilled in the art person can be under the situation that does not break away from spirit and scope of the present utility model; also can make all equivalent transformations, these equivalent transformations all should be included in the scope of patent protection of the present utility model.
