Description

LCD panel frame assembly structure

technical field

The utility model relates to a frame assembly structure of a liquid crystal panel, in particular to an improved structure of a frame of a liquid crystal panel which is formed by stacking corner joints and forming integrally by punching and riveting.

Background technique

Generally, a thin display device such as a liquid crystal display mostly uses a metal frame to fix the panel and the backlight module. Such known metal frames are usually formed by stamping a large-area metal sheet, that is, the required part of the frame is reserved on the entire sheet metal, and the rest are completely stamped and cut. The disadvantages caused by this traditional processing method Because of material consumption and high cost, at the same time, the stress of this stamping forming method is too concentrated, which makes the flatness unsatisfactory.

In order to improve the above-mentioned shortcomings, there are L-shaped or long-strip workpieces butt joints to form a frame. Although it has the advantages of saving consumables and reducing costs, it is not easy to position accurately in the joint combination method, and skew deviations are often formed at the joints, making joints Poor texture and flatness.

Utility model content

The main purpose of the present invention is to provide a liquid crystal panel frame assembly structure, which can strengthen the structural strength of the overall panel frame, and effectively improve the flatness and joint quality of such frames.

In order to achieve the above-mentioned purpose, the frame of the liquid crystal panel of the present utility model is composed of a first frame piece with the same shape up and down and a second frame piece with the same shape on the left and right sides; There are masks on both sides of the front; the second frame is provided with a side flap matching the width of the end flap of the first frame, and an inner flap is formed at the position where the side flap is opposite to the above-mentioned cover sheet. The front side is provided with an inner concave sheet at the position opposite to the mask; the covers of the first frame are stacked up and down on the relative inner folds of the second frame, and the masks are stacked on the front and back of the second frame. Each inner concave piece; the above-mentioned overlapping corner positions are punched and riveted to form an integral riveted convex portion and an integrated riveted concave portion, which are used at each punched riveting position to form a convex riveted end wall and a concave riveted end wall that are interlocked with the inner and outer cone walls.

In a preferred embodiment, the above-mentioned inner concave sheet has an inner inclined guide surface matching the thickness of the material.

In an ideal embodiment, a notch is formed between the side flange of the second frame member and the inner concave piece.

Detailed ways

The advantages and other features of the present utility model will be described in detail in conjunction with the following preferred embodiments of the accompanying drawings.

First please refer to Fig. 1, in the preferred embodiment shown in the figure, the metal frame of the liquid crystal panel of the present invention is composed of the first frame parts 10, 11 of the same shape up and down, and the second frame parts 20, 21 of the same shape on the left and right sides. constitute.

Taking one of the first frame member 10 and the second frame member 20 as an example, as shown in Figure 2 and Figure 5, the first frame member 10 contains end flaps 12 to form two side covers 14, and the two sides of the front side are The notch is punched to form a mask 13 with a small area. The second frame member 20 is provided with a side flap 22 with a width matched to the end flap 12 of the first frame member 10, and a small-width inner flap 24 is formed at the position where the side flap 22 is opposite to the above-mentioned cover sheet 14, and at the same time, An inner concave sheet 23 is provided at a position opposite to the above-mentioned small-area mask sheet 13 . In the preferred embodiment shown in the figure, the above-mentioned inner concave piece 23 is preferably punched and formed with an inner inclined guide surface 28 matching the thickness of the material. At the same time, a slot 29 is formed between the above-mentioned side flange 22 and the inner concave piece 23 to facilitate folding and forming.

As shown in Fig. 1, Fig. 6 and Fig. 7, the above-mentioned first frame parts 10, 11 and second frame parts 20, 21 can make their four corners overlap each other initially, so that each of the first frame parts 10, 11 The cover sheet 14 is stacked up and down on the opposite inner flaps 24 of the second frame members 20, 21; meanwhile, the mask sheets 13 of the first frame members 10, 11 are stacked on each of the second frame members 20, 21 front and back. Inner concave sheet 23.

Referring now to Fig. 2, Fig. 3, Fig. 4 and Fig. 8, the above-mentioned overlapping corner positions can be punched and riveted to form an integral riveting convex portion 15 and an integral riveting concave portion 25, which are used in the formation of the group of punching and riveting positions. The convex riveted end wall 16 and the concave riveted end wall 26 of the outer cone walls 17 and 27 are engaged.

According to the above-mentioned improved structure, the utility model has the advantages of good overall structural strength, fast processing and flat frame body because each corner position is stacked and riveted separately. The wall can effectively improve the flatness and texture of the joints of this type of frame.

The above examples are only used to illustrate the utility model for convenience, and are not intended to be limiting. Without departing from the scope of the utility model, various simple changes and modifications that can be made by those skilled in the art should still be included in the present invention. within the scope of the claims.
