Abstract

An LED display screen rear cover is provided, which is characterized in that: the cover comprises a shell provided with a holding cavity cooperated with an LED display screen frame and used for containing a display screen module, a PCB board and circuit components; a curved surface transiting smoothly is provided on the external surface of the shell from the shell edge to the back. The shell is cast by ABS engineering plastics; at least one heat sinking hole is opened on the top or / and back; two lower gaps are processed on the shell bottom and two lateral gaps are processed on the lateral side of the shell. A covering board of the heat sinking hole is provided on the heat sinking hole on the back of the shell and heaves are provided on the corresponding position of the heat sinking hole on the covering board to shade the heating sinking hole face. The utility model provides a light LED display screen rear cover with light quality, few processing times, high processing technology precision, easy assembly and beautiful appearance and capable of equipping the display screen with better heat dissipating performance and avoiding dust from falling into the display from the heat sinking holes.

Description

The LED display bonnet

[technical field]

The utility model relates to LED display, is specifically related to the improvement to the LED display rear cover structure.

[background technology]

The LED display structure mainly is made of display screen screen, LED display framework and back cover.The module, components and parts and the circuit pcb board that constitute display frame place in the LED display framework, on the plane, framework front and back that LCDs and back cover are separately fixed at.At present, the LED display bonnet generally adopts iron plate or alloy sheets punch process to form, and this processing mode volume in manufacture process is big, and quality is heavy, and technological level is low, is difficult to guarantee preferably dimensional accuracy, and outward appearance is not very attractive in appearance.How in addition, can produce the heating phenomenon during owing to the work of circuit elements device, therefore, also be one of improved main points of present display device structure for radiator provides radiating condition better.

[utility model content]

Technical problem to be solved in the utility model is to overcome the defective that exists in the present above-mentioned prior art, a kind of light weight, processing technology precision height are provided, can make display have better heat dispersion and can avoid dust to fall into LED display bonnet in the display from louvre.

The technical scheme that the utility model proposed is:

A kind of LED display bonnet, it is characterized in that: comprise a housing, described housing is provided with the containing cavity that can cooperate with the LED display framework, be used for holding display panel module, pcb board and circuit elements device, in housing outer surface from shell rim to the back, the cambered surface of a rounding off is arranged.

Described housing adopts the casting of ABS engineering plastics to form.

Described case top is or/and the back offers at least one louvre.

Described housing bottom is processed with two following breach.

On the louvre of described housing back, also be provided with the louvre covering plate, the position corresponding with louvre on this covering plate is equipped with the projection that can block louvre hole face.

Described housing side also is processed with two side breach.

The utlity model has following technique effect:

1) the utility model matches with display frames, and its shell rim adopts the design of arc transition shape to the back, and the lines transition is natural, curve is slick and sly, can be convenient to the landing of daily dust, reduces cleaning time.

2) a plurality of louvres of offering in housing end face and back surfaces of the utility model, can further improve the display heat dispersion, especially overleaf add the projection of an arcuation on the through hole, when improving radiating condition, can hide louvre hole face, avoid dust to fall in the display, pollute the circuit elements device from louvre.

3) the utility model housing adopts resin material casting one-shot forming, can reduce the processing number of times, reduces the technology cost, and light, easy assembling can make entire product surface one integrated mass simultaneously, and is very attractive in appearance.

[embodiment]

As Fig. 1～shown in Figure 4, the utility model is for to be made of a housing 1 with containing cavity, described containing cavity can match with the LED display framework, be used for holding display panel module, pcb board and the circuit elements device etc. that are loaded on the framework, described housing 1 outer surface has the cambered surface 2 of a rounding off from shell rim to back, containing cavity also is an arc cavity.Cover the back side after present inclined-plane or straight plane, this design can make LED display reduce machining stress during fabrication, and simultaneously, this convex structure also is convenient to the landing of daily dust, can reduce cleaning time.

As Fig. 2, shown in Figure 4, the utility model offers top louvre 7 at housing 1 top, also offers back louvre 3 in housing 1 back surfaces, is provided with breach 6 down in housing 1 bottom, has preferable heat dispersion to guarantee display.Though but louvre too much helps the improvement of heat dispersion, dust falls into from the hole in the display easily, and the time one is long, when being collected on the components and parts, is unfavorable for the heat radiation of components and parts on the contrary, and cleaning also bothers very much.Therefore, the utility model is on back louvre 3, be provided with louvre covering plate 8, also offer the through hole corresponding on this covering plate, and, be equipped with an arcuation projection in the position of each louvre correspondence with each louvre, be used to hide louvre 3 hole faces, both helped the heat radiation and the ventilation of components and parts, and can avoid dust to fall in the display simultaneously, polluted the circuit elements device from louvre 3.

The utility model is corresponding with the LED display framework to be cooperated in order to make, and as shown in Figure 2, on four angles, housing 1 edge, all is processed with corresponding breach 4.

For ease of the installation of the part of display own, when display uses assembling and guide and support, as shown in Figure 2, the utility model is in housing 1 side, but also is processed with the side breach 5 of two grasping.

The utility model housing 1 can adopt ABS engineering plastics castings to form, and adopts this material can reduce the weight of bonnet, light, easy assembling, integrated mode can make that entire product is disposable and finish processing, can reduce the processing number of times, guarantees machining accuracy, reduce the technology cost, and very attractive in appearance.
