Technical Field

The invention relates to the technical field of flat-panel televisions, in particular to a direct type narrow-frame flat-panel television module.

Background

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides a direct type narrow-frame flat-panel television module, which is used for improving the structural design of the problem of installing and fixing a screen and controlling foreign matters in the module. Realize that the fixed screen installation is stable, reduce the cost of labor, eliminate the piece and disturb.

The technical scheme is as follows: in order to achieve the purpose, the invention adopts the technical scheme that:

a direct type narrow-frame flat-panel television module comprises a front shell, a fixed screen, an optical diaphragm, a light bar and a metal back plate which are sequentially arranged; an integrated rubber frame is arranged between the fixed screen and the optical diaphragm; the integrated rubber frame is clamped into a clamping groove of the metal back plate in a clamping manner;

the integrated rubber frame is provided with a buffer rubber strip on one side in contact with the fixed screen, and a plurality of rubber frame limiting pads are arranged on the peripheral side of the integrated rubber frame.

Furthermore, the buffering rubber strip and the rubber frame limiting pad are integrally formed with the integrated rubber frame by adopting an injection molding method.

Further, the integral rubber frame is preferably made of polyester resin.

Furthermore, a front shell buffering rubber strip is arranged on one side, in contact with the fixed screen, of the front shell.

Furthermore, a plurality of membrane support frames used for supporting the optical membranes are arranged on the metal back plate, and the membrane support frames and the light bars are arranged in a staggered mode.

Has the advantages that: the direct type narrow-frame flat television module provided by the invention has the following advantages:

(1) adopt modified gluey frame structural design, cancel 4 gluey frame buffer rubber strips and 19 gluey frame spacing pads that paste on the gluey frame, can let screen OPENCELCELL with glue frame direct soft contact to reduce the cost of material and production manual work.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 2, the direct-type narrow-frame flat panel television module includes a front housing 1, a fixed screen 3, an optical film 10, a light bar 12, and a metal back plate 13, which are sequentially installed. An integrated rubber frame is arranged between the fixed screen 3 and the optical diaphragm 10. The integral rubber frame is clamped into the clamping groove of the metal back plate 13 in a clamping manner. The integrated rubber frame is provided with a buffer rubber strip 5 on one side contacting with the fixed screen 3, a plurality of rubber frame limiting pads 4 are arranged on the periphery of the side face, and the buffer rubber strip (5) and the rubber frame limiting pads (4) are integrally formed with the integrated rubber frame by an injection molding method.

The integral rubber frame is preferably made of polyester resin (PET), which is a milky white or light yellow polymer with high crystallinity and smooth and glossy surface. Creep resistance, fatigue resistance, abrasion resistance, good dimensional stability, small abrasion and high hardness, and has the maximum toughness in thermoplastic plastics: the electric insulation performance is good, the temperature influence is small, but the corona resistance is poor. The plastic frame is made of PET, and the buffering rubber strips and the surrounding limiting pads are directly injected in the design of the plastic frame. The design improvement can reduce the generation of foreign matters in the module and reduce the product cost. The integral rubber frame comprises an integral injection molding upper rubber frame 6, a lower rubber frame 7, a left rubber frame 8 and a right rubber frame 9.

In order to protect the fixed screen 3, a front shell buffer rubber strip 2 is arranged between the front shell 1 and the fixed screen 3.

The metal back plate 13 is provided with a plurality of membrane supporting frames 11 for supporting the optical membranes 10. The diaphragm support frame 11 and the light bar are arranged in a staggered mode.

During installation, the fixed screen 3 is clamped between the front shell 1 and the metal back plate 13 through the front shell buffer rubber strip 2 and the integrated rubber frame. The limiting pad on the integrated rubber frame has a limiting effect on the fixed screen 3. The integrated rubber frame is clamped on the metal back plate 13, and the optical diaphragm 10 is fixed on the diaphragm support frame 11 on the metal back plate 13. The optical film 10 is provided with a plurality of sheets. Light bars 12 are further arranged between the optical diaphragm 10 and the metal back plate, and the light bars and the diaphragm support frame 11 are arranged in a staggered mode.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
