Abstract
The utility model relates to a combined after frame of LCD, which consists of a metal frame and a metal backplate, wherein the metal frame comprises an upper metal rib, a lower metal rib, a left metal rib and a right metal rib, the two ends of the left metal rib are fixedly connected to the left sides of the upper and lower metal ribs respectively, the two ends of the right metal rib are fixedly connected with the right sides of the upper and lower metal ribs respectively, the height of the metal frame is matched with the height of the metal backplate, and when installation is completed, the upper and lower edges of the metal backplate are fixedly connected with the upper and lower metal ribs, and the metal backplate is fixedly connected with the left and right ribs respectively. By adopting the structure, the utility model has the advantages of saved material, lowered weighted, reduced module cost, reduced tonnage of punching machine processing, self-mounted reflective sheet, and excellent radiating property.
Description
Technical field
The utility model relates to the liquid crystal indicator technical field, refers in particular to the combined type after-frame on a kind of in light weight, LCDs that cost is low.
Background technology
At present, as shown in Figure 1, the after-frame of prior liquid crystal display is normally directly stamping forming by a thicker sheet metal, before after-frame, be added with reflector plate, the after-frame of this traditional structure adopts certain thickness sheet metal can guarantee the firm of after-frame, during making, need to adopt the large-tonnage punch press to carry out punching press, production technology cost and die cost are higher, and, the cost of the certain thickness sheet metal of one monoblock is also higher, how to improve the back mount structure of LCDs, and making after-frame promptly firmly reduce cost again to become has problem to be solved.
Summary of the invention
The combined type after-frame of the LCDs that the purpose of this utility model is exactly provide at the deficiencies in the prior art part a kind of in light weight, sound construction, thermal diffusivity is good, cost is low.
For achieving the above object, the combined type after-frame that the utility model is positioned at the LCD back is made of metallic framework and metal backing panel, wherein, metallic framework includes: going up metal rib, following metal rib, left metal rib and right metal rib, fixedlys connected with the left side of following metal rib with last metal rib respectively in the two ends of left metal rib; Fixedly connected with the right side of following metal rib with last metal rib respectively in the two ends of right metal rib; The height of described metallic framework and described metal backing panel height match, after the assembling, the last lower limb of described metal backing panel is fixedlyed connected with last metal rib, following metal rib respectively, and described metal backing panel is also fixedlyed connected with right metal rib with left metal rib respectively.
Described metal rib, following metal rib, left metal rib and the right metal rib gone up is made by thicker sheet metal.
Described metal backing panel is by aluminium base reflecting plate impact briquetting.
Being fixedly connected as by attachment screw between described each parts is fastenedly connected.
Rivet is passed through in being fixedly connected as between described each parts.
Be fixedly connected as welding between described each parts.
After adopting said structure, the structure of this novel employing metallic framework, sound construction, because its metal backing panel can adopt thin plate to make, can economical with materials, weight reduction reduces die cost, because, the metal backing panel is more less than monoblock after-frame, is adding the punch press processing that can adopt less tonnage man-hour like this, thereby is reducing the technology cost, when the metal backing panel adopts aluminium base reflecting plate, just can carry reflector plate, when liquid crystal module is assembled, not need to paste reflector plate again, convenient and reliable, can stop the Mura phenomenon that causes owing to the reflector plate perk fully, and significantly promote heat dispersion.As from the foregoing, the utlity model has can economical with materials, weight reduction, reduce die cost, reduce the processing punch press tonnage, can carry characteristics such as reflector plate, perfect heat-dissipating.

Embodiment
As Fig. 1-Fig. 4, the combined type after-frame that the utility model is positioned at the LCD back is made of metallic framework 10 and metal backing panel 20, wherein, metallic framework 10 includes: going up metal rib 11, following metal rib 12, left metal rib 13 and right metal rib 14, fixedlys connected with the left side of following metal rib 12 with last metal rib 11 respectively in the two ends of left metal rib 13; Fixedly connected with the right side of following metal rib 12 with last metal rib 11 respectively in the two ends of right metal rib 14; The height of described metallic framework 10 and described metal backing panel 20 highly match, after the assembling, the last lower limb of described metal backing panel 20 is fixedlyed connected with last metal rib 11, following metal rib 12 respectively, and described metal backing panel 20 is also fixedlyed connected with right metal rib 14 with left metal rib 13 respectively.
Described metal rib 11, following metal rib 12, left metal rib 13 and the right metal rib 14 gone up is made by thicker sheet metal.
Described metal backing panel 20 is by aluminium base reflecting plate impact briquetting.
Fixedly connected can be by attachment screw between described each parts is fastenedly connected.
Fixedly connected can be between described each parts passed through rivet.
Fixedly connected between described each parts can be welding.
Like this, the structure of this novel employing metallic framework 10, sound construction, because its metal backing panel 20 can adopt thin plate to make, can economical with materials, weight reduction reduces die cost, because, metal backing panel 20 is more less than monoblock after-frame, is adding the punch press processing that can adopt less tonnage man-hour like this, thereby is reducing the technology cost, when metal backing panel 20 adopts aluminium base reflecting plate, just can carry reflector plate, when liquid crystal module is assembled, not need to paste reflector plate again, convenient and reliable, can stop the Mura phenomenon that causes owing to the reflector plate perk fully, and significantly promote heat dispersion.As from the foregoing, the utlity model has can economical with materials, weight reduction, reduce die cost, reduce the processing punch press tonnage, can carry characteristics such as reflector plate, perfect heat-dissipating.
