Specific embodiment
Although operations are described as the processing of sequence by flow chart, many of these operations can by concurrently,
Concomitantly or simultaneously implement.The sequence of operations can be rearranged.Processing can be terminated when its operations are completed,
It is also possible to have the additional step being not included in attached drawing.
It may have been used term " first ", " second " etc. herein to describe each unit or module, but these lists
Member or module should not be limited by these terms, and the use of these items is only for carry out a unit and another unit
It distinguishes or a module is distinguished with another module.Term "and/or" used herein above includes one of them or more
Any and all combinations of listed associated item.When a unit referred to as " connects " or " coupled " to another unit
When, it can be connected or coupled to another unit, or may exist temporary location.
Term used herein above is not intended to limit exemplary embodiment just for the sake of description specific embodiment.Unless
Context clearly refers else, otherwise singular used herein above "one", " one " also attempt to include plural number.Also answer
When understanding, term " includes " and/or "comprising" used herein above provide stated feature, integer, step, operation,
The presence of unit and/or component, and do not preclude the presence or addition of other one or more features, integer, step, operation, unit,
Component and/or combination thereof.
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
Be as shown in Figure 1-Figure 3 a kind of LED display for providing, shown in figure LED display body structure,
LED display module 30 and the power supply box 40 being arranged on body structure, the body structure include: die casting cabinet 10 and with institute
Die casting cabinet 10 is stated by the plastic molding portion 20 of plastic cement die casting machine encapsulating die cast, the shape in the plastic molding portion 20 with
The shape of the die casting cabinet 10 is adapted, and the plastic molding portion 20 is covered on the die casting cabinet 10.Since LED is shown
The display of screen requires higher and higher, and matrix closeness is closer and closer, thus the required precision of the body structure to LED display
Higher and higher, in the prior art, body structure generallys use aluminium alloy and magnesium alloy pressure-casting goes out die casting cabinet, then by processing
The heart carries out further Precision Machining to die casting cabinet, and die casting cabinet is made to reach dimension precision requirement.And in the present embodiment, pass through
Die casting cabinet is first manufactured, a plastic molding portion, modeling are directly then formed by plastic cement die casting machine encapsulating on die casting cabinet again
Gum forming portion is covered on die casting cabinet, due to having good surface size when nanometer PPC molding, can be very good to reach essence
Degree requires, and then forms the surface structure for reaching size requirement, no longer needs to carry out further finishing passes, reduces cabinet
Processing cost.
Specifically, the plastic molding portion can be a nanometer PPC material in the present embodiment.Nanometer PPC material has good
Plasticity, and have good surface texture.
In the present embodiment, as shown in figure 4, the die casting cabinet 10 includes intermediate cross support 13 and with described ten
The square frame 14 that shaped support frame 13 connects, the plastic molding portion is covered on 13 top of cross support frame and grade
It is covered on 14 top of square frame.Since cross support frame 13 and square frame 14 are aobvious for being directly connected to LED
Show in mould group, plastic molding portion is moulded directly into cross support frame 13 and 14 top of square frame makes this part of the surface structure
Reach dimension precision requirement, while other positions are covered without plastic molding portion, reduce the requirement of material, cost is lower.
As described in Figure 3, the first mounting hole 11 for fixing LED display module 30 is provided on the die casting cabinet 10,
The corresponding position in the plastic molding portion 20 is also equipped with corresponding second mounting hole 21, so that LED display module can be with
It is directly connected to the first mounting hole 11 on die casting cabinet 10 by second mounting hole 21, there is better bonding strength.
