Abstract

The utility model provides a metal frame, a backlight module and a liquid crystal display device. According to the fact that reinforcing ribs are arranged on the metal frame and in areas behind light sources along the arrangement directions of the light sources, the problem that the strength of the light source structure of the backlight module is not strong is resolved, the strength of the metal frame and in the arrangement directions of the light sources is improved, and therefore when the backlight module is impacted and falls off, and the radios that the light sources are pressed to cause light explosion and a screen glass is damaged are reduced. Meanwhile, structure strength of the liquid crystal display device is improved.

Description

A kind of metal frame, backlight module and liquid crystal indicator

Technical field

The application relates to electronic display unit, relates in particular to a kind of metal frame, backlight module and liquid crystal indicator.

Background technology

Along with a large amount of of electron trade product popularize, the user is more and more exquisite to product, and the quality of product is had higher requirement, and he user wishes that not only product is lighter, thinner, screen is larger, wish also that simultaneously product can stand certain collision, fall, have certain intensity.

Please refer to Fig. 1 and Fig. 2, in the existing backlight module, the base 111 on the metal frame 11 is nearer apart from light source 12, and undercapacity.When the stressed past middle extruding in two ends, metal frame bottom, the easy compressive deformation in base, thus cause the quick-fried lamp of light source or screen glass breakage.So existing backlight module can't arrive higher requirement of strength, its strength characteristics is still waiting to improve.

The utility model content

The main technical problems to be solved in the utility model is, a kind of metal frame, backlight module and liquid crystal indicator are provided, and solved the problem of backlight module light source place structural strength deficiency.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of metal frame, it is used for backlight module; On described metal frame, in light source zone behind, be provided with reinforcement; Described reinforcement arranges along described light source orientation.

Further, described reinforcement is the metal of a strip.

Further, described reinforcement is arranged between two ends of described metal frame lower end.

Further, described metal frame base extends to described reinforcement, and coupled.

Further, on described metal frame, in the zone between described reinforcement and the light source, be provided with at least one through hole.

Further, be provided with on the described reinforcement and reinforce the limit, described reinforcing limit is formed to any lateral buckling of its width by described reinforcement top.

Further, described reinforcement top is 90 degree or 180 degree to any lateral buckling angle of its width.

The utility model also provides a kind of backlight module, comprising: LGP, light source; Also comprise: above-mentioned metal frame.

The utility model also provides a kind of liquid crystal indicator, comprising: display panels, power circuit; Also comprise: above-mentioned backlight module.

The beneficial effects of the utility model are: a kind of metal frame, backlight module and liquid crystal indicator are provided, and by on metal frame, light source arranges reinforcement along the light source orientation in the zone behind.Metal frame and the backlight module intensity in the light source orientation is got a promotion, thereby reduce the backlight module collision, when falling, the quick-fried lamp of light source pressurized that causes and the probability of screen glass breakage.

The specific embodiment

For making the technical solution of the utility model and advantage clearer, by reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment.

The overall thinking of the utility model is: by at backlight module metal frame light source place reinforcement being set, thereby improve the pressurized of whole metal frame and backlight module, strengthen the structural strength of backlight module.And reinforcement concrete that form is set is as follows:

In order to strengthen the structural strength at light source place, make it reduce the under external force probability of quick-fried lamp, in the present embodiment, reinforcement can be arranged on the metal frame, because metal frame in light source zone behind intensity a little less than, so preferably reinforcement need to be arranged in the zone corresponding to the light source behind; And further better for the structural strength that makes reinforcement, reinforcement can be arranged along the light source orientation, like this; when the stressed past middle extruding in metal frame lower end, reinforcement can bear pressure, stops the further compressive deformation of metal frame; thereby protection light source and screen make it not impaired.

Please refer to Fig. 3 and Fig. 4, in the present embodiment, play the better effect of gaining in strength in order to make reinforcement, more excellent, reinforcement 311 can be set to the metal of strip, and it is arranged between outstanding two ends (312 and 313), metal frame 31 bottoms.And the metal frame base extends to this reinforcement 311, and links to each other with reinforcement 311, the breach between two

ends

312 and 313 of metal frame 31 bottoms is reduced, and further metal frame 31 bottom surfaces and reinforcement are linked to be an integral body; Improve to greatest extent the structural strength of metal frame 31.

On metal frame 31, because more existing zero device is to be placed on the originally indentation, there between two ends, metal frame bottom.Please refer to Fig. 5 and Fig. 6, and in the present embodiment, because the base is linked to each other with reinforcement, the breach at both ends is reduced, so more excellent in placing in this position the metal frame of parts 61, more excellent, can offer the through hole 314 of placing parts 61 at described metal frame 31, the quantity of through hole 314 and the parts of required placement 61 quantity are complementary.

Please refer to Fig. 7 and Fig. 8, the form that arranges of reinforcement 311 can only be vertical protruding 81 of strip; But in the present embodiment, the intensity of reinforcement 311 is got a promotion, concrete method to set up is reinforced the limit for arranging at reinforcement 311, the mode of reinforcing the limit preferably is set is the top with reinforcement, namely vertically the top of projection 81 to towards or dorsad the direction bending of described light source form, be that it can inwardly and outwards bend, and more excellent bending mode can make the top end face of reinforcement 311 to light source direction bending 90 degree as shown in Figure 9 and Figure 10, and namely the reinforcement shown in Figure 10 is the bending 101 of L-type; Perhaps such as Figure 11 and the mutually light source double flat of reinforcement 311 top end faces that makes shown in Figure 12, make it be folded into the end, namely as shown in Figure 12 the reinforcement 311 that makes is U-shaped bending 121.Above setting can both make the structure of reinforcement further be strengthened, and increases its structural strength.

The utility model is except providing above metal frame, and uses outside the backlight module of this metal frame, and a kind of liquid crystal indicator also is provided, and it comprises the backlight module of mentioning in display panels, power circuit and this above-described embodiment.

Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
