Abstract
The utility model discloses an integral type backplate for strip -shaped screen, it includes that a bottom plate and bipartition are bie certainly the curb plate that up extend the bottom plate both sides, bottom plate lower extreme face is formed with many mutual spaced slots, the curb plate is from the up end inboard sunken step that is formed with down, the step forms to two upper and lower steps form with the bottom plate up end, and the lamp strip of display screen can be fixed in the vertical part between step and the bottom plate up end, the liquid crystal glazing of display screen can be supported in on the step, and the setting of slot not only can increase the heat radiating area of backplate for heat dispersion is good, but also can strengthen the mechanical properties of backplate, and can also alleviate the holistic weight of backplate.
Description
Technical field
This utility model is related to a kind of line-screen, more particularly, to a kind of integral type backboard for line-screen.
Background technology
In actual module production process, backboard is fixedly connected with center, and center is fixedly connected lamp bar and supports liquid
Crystal glass, so backboard plays the effect supporting whole module and heat conduction.In some outdoor displays, some line-screens need
Super brightness (traditional room brilliancy only need to 500nits about), brightness needs to reach more than 1200nits it is therefore desirable to increase
The power of lamp bar, and have part can change into heat energy during electric energy is converted into luminous energy simultaneously, if heat can not guide,
Can cause local hyperpyrexia can impact to the LED lamp life-span, cause product bad, thus needing backboard to have good radiating work(
Energy；Additionally, in rail communication project, due to the factor such as vibratory impulse of product, but need the high lightweight bar shaped of intensity
Screen products.
In order to pursue the frivolous of product, as shown in figure 1, the backboard 10 of conventional strip screen is one piece than relatively thin metallic plate
Material, then according to demand is processed screw hole etc..Such backboard is entire surface radiating, but area of dissipation is relatively small,
Heat dispersion is not good；And in mechanical processing industry, the machining of metal can produce substantial amounts of heat, and the course of processing is easy for
Produce the deformation that heat causes backboard, along with processing screw hole more affects its intensity, i.e. the bad mechanical strength of backboard, if
Increase its intensity by increasing the thickness of backboard, its overall weight will increase, and does not meet demand；Furthermore, backboard and center
Locked by screw, during locking, easily send out dirt, and sending out dirt is to need most the project forbidden during module group assembling.
Utility model content
The purpose of this utility model is to provide a kind of integral type backboard for line-screen, its perfect heat-dissipating, and
High mechanical strength is moreover it is possible to provide facility for the subsequent production of product.
For achieving the above object, this utility model be the technical scheme is that
A kind of integral type backboard for line-screen, up extends from described base plate both sides respectively including a base plate and two
Side plate, described base plate lower surface is formed with a plurality of spaced groove, described side plate down concave shape from inside upper surface
Cheng Youyi step, it is step-like that described step and base plate upper surface are formed as upper and lower two.
Described groove extends along the length direction of described base plate.
The beneficial effects of the utility model are: it is step-like, thus showing that described step and base plate upper surface are formed as upper and lower two
The lamp bar of display screen can be fixed in the vertical section between two steps, and the liquid-crystalline glasses of display screen can be supported on the described back of the body
On pallet rank, thus being equivalent to the function that this utility model backboard is integrated with backboard and center, that is, backboard is integrated with center, from
And it is the subsequent production offer facility of product；Additionally, because base plate lower surface is formed with a plurality of spaced groove, thus increasing
Add the area of dissipation of backboard, so heat dispersion is good, that is, be equivalent to the work(that this utility model backboard is also integrated with fin
Can, that is, be equivalent to the integrally-formed backboard of the present utility model of backboard, center, fin；Additionally, the setting of groove
Not only enhance the mechanical performance of backboard, also reduce the overall weight of backboard.

Specific embodiment
As shown in Fig. 2,3,4,5,6, the integral type backboard that this utility model is used for line-screen includes a base plate 1 and two points
The side plate 2 up not extended from described base plate 1 both sides, described base plate 1 lower surface is formed with a plurality of spaced groove 11, institute
State side plate 2 from inside upper surface down depression be formed with a step 21, described step 21 is formed as upper and lower two with base plate 1 upper surface
Step-like.
Preferably, described groove 11 is along the length direction extension of described base plate 1.
As described above, to be formed as upper and lower two step-like, thus the lamp bar of display screen can described step 21 and base plate 1 upper surface
To be fixed in the vertical section 22 between described step 21 and base plate 1 upper surface, the liquid-crystalline glasses of display screen can be supported
On described step 21, thus being equivalent to the function that this utility model backboard is integrated with backboard and center, i.e. backboard and center one
Body, so, decreases follow-up screw locking backboard and the processing step of center, product later is sent out with dirt and also can play very
Good control action；Additionally, because base plate lower surface is formed with a plurality of spaced groove 11, thus increased dissipating of backboard
Hot area, so heat dispersion is good, that is, is equivalent to the function that this utility model backboard is also integrated with fin, that is, phase
When in the integrally-formed backboard of the present utility model of backboard, center, fin；Additionally, the setting of groove 11 not only enhances
The mechanical performance of backboard, so as to energy anti-vibrating and impact, also reduces the overall weight of backboard, can reach the frivolous demand of product.
In the present embodiment, preferably, described backboard adopts section bar to mold, thus the mould development of early stage relatively holds
Easily, and carry out following process after mould held successfully by section bar, the process-cycle can also shorten, and die cost is also very just simultaneously
Preferably.
