Description

Body after a kind of closed LED display module

Technical field

The utility model relates to body after a kind of closed LED display module, belongs to LED display field.

Background technology

The minimum Component units of LED display is module, and module is made up of face shield, lamp plate, rear body, adopts many screws to fix between three.Rear body has played protection, has improved flatness, has increased the effects such as module intensity, connect box, and high-intensity rear body and screw can be fixed as satisfactory plane by the lamp plate of warpage.After existing module, body generally adopts " square shape ", " saying " font and " matrix pattern " three kinds of structures, the conservation consumption of " mouth " font, but its intensity and flatness will be lower than other two kinds, especially module core is owing to not having rear body structure to fix, screw cannot be beaten on rear body, easily occurs that arch upward in module center or recessed phenomenon.And the effect of matrix pattern structure is better than " square shape " structure, the rear body of day character form structure falls between.But after existing display screen, body adopts PC+ glass fiber material single injection-molded substantially, its intensity and rigidity are subject to certain restrictions itself, the module that particularly area is larger is as the module of the 240mm*240mm size of standard box bodies use, even if sphere of movements for the elephants shape structure also cannot play good effect.And most of circuit at the module back side of body structure is all outside exposed after above-mentioned three kinds, because LED display adopts the control of low pressure digital element device, be easy to because following reason causes damage, 1. reveal copper region from current potential different conductor contact with it.2. contact with the object with static.3. violent collision and friction.

Summary of the invention

For the deficiencies in the prior art, the utility model provides body after a kind of closed LED display module.The utility model structure makes the performance of body after the module of external member intensity, display screen flatness and three kinds of structures mentioned above have great lifting.

In order to achieve the above object, the utility model adopts following technical scheme: body after a kind of closed LED display module, rear phosphor bodies comprises outside framework, reinforcement and filling face, between outside framework and reinforcement, has filling face, thereby the circuit at the lamp plate back side is played to effective protective effect; In addition, the screw of module all can be contained on rear body, and the reinforcement that adopts scope to spread all over whole rear body (or drain pan) carries out integral reinforcing to module.

As further preferred, described outside framework is square structure.

As further preferably, filling face can not exceed the height of outside framework, space, middle layer that should be between outside framework and reinforcement, and intensity is higher like this, has reinforcement effect, rear body to be not easy to be out of shape in face of filling below.

As further preferably, on filling face, have louvre, with the heat-sinking capability that ensures that display screen is good.

As further preferably, the structure of reinforcement is seen as additional one of " rice " font structure being centrosymmetric and is large " ten " font and combines from rear body front, and this structure is done two-way stretch along the normal direction of filling face again, and rear body front, with lamp plate joint face.

As further preferred, the height of reinforcement should be higher than outside framework height.

As further preferably, on rear body, there are 4 perforates, be used as the outlet of input/output signal terminal and power lead outlet.

As further preferably, rear body front, with lamp plate joint face, the reinforcement height between 4 perforates should carry out reduction to a certain degree, reduces height can facilitate power lead to reach position of opening and be as the criterion from drain pan (or body) inside.

As further preferred, rear body front, with on lamp plate joint face is provided with double-screw bolt, has screw hole in double-screw bolt, and screw hole position is corresponding with the screw hole on lamp plate, face shield.

As further preferred, double-screw bolt height should be identical with outside framework height.

The beneficial effects of the utility model are: the utility model provides body structure after a kind of closed LED display module, has filling face, thereby the circuit at the lamp plate back side is played to effective protective effect between outside framework and reinforcement; In addition, the screw of module all can be contained on rear body, and the reinforcement that adopts scope to spread all over whole drain pan carries out integral reinforcing to module.The utility model structure makes the quality of body after the module of three kinds of structures described in external member intensity, display screen flatness and background technology have great lifting.

Embodiment

Realization, functional characteristics and the beneficial effect of the utility model object, be described further below in conjunction with specific embodiment and accompanying drawing.

Below in conjunction with the drawings and specific embodiments, technical scheme described in the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As Figure 1-3, after the utility model embodiment display screen, body comprises outside framework 1, filling face 2 and reinforcement 3.Wherein:

Outside framework 1 is square structure, and rear body is of a size of 240mm*240mm.Employing single injection-molded is made, and filling face 2 is the filling part in space in outside framework, and thickness is 1mm, directly outside not exposed with guard lamp printed line road;

As shown in Figure 4, filling face 2 is positioned at middle layer, is connected with the midline position of outside framework 1.

On filling face 2, have louvre 4, the similar window shutter of louvre 4 shape.To ensure the good heat-sinking capability of display screen.

Reinforcement 3 is positioned on filling face 2, and its structure is seen as additional one of 4 " rice " font structures that are centrosymmetric and is large " ten " font and combines from rear body front, and this structure is done two-way stretch along the normal direction of filling face 2 again.

The height of reinforcement 3 is highly identical with outside framework 1.

On rear body, there are 4 perforates 5, are used as the outlet of input/output signal terminal and power lead outlet,

Rear body front, with lamp plate joint face, the reinforcement height between 4 perforates should carry out reduction to a certain degree, reduces height and is as the criterion can facilitate power lead body inside from drain pan to reach position of opening

Rear body front, with on lamp plate joint face is provided with double-screw bolt 6, in double-screw bolt 6, has screw hole, and screw hole position is corresponding with the screw hole on lamp plate, face shield.Double-screw bolt 6 height should be highly identical with outside framework 1.

After drain pan, the body back side is provided with M3 metal screw 7, can be fixed on casing.

Filling face 2 material used is identical with rear body, and whole rear body adds glass single injection-molded with pc.
