Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
It should be noted that in the utility model embodiment about direct-light-type backlight 100, backboard 10, optical module 20,
Although the appended drawing reference of bracket 30, pedestal 31 and support column 32 is identical as the appended drawing reference of corresponding component in the prior art,
But the appended drawing reference is only intended to refer to each component part appeared in attached drawing, is not meant to each component part at this
Specific structure and the specific structure of corresponding component part in the prior art in embodiment is consistent.
Fig. 5 show the structure in the preferred embodiment in the utility model for the direct-light-type backlight 100 of liquid crystal display
Schematic diagram.The direct-light-type backlight 100 includes optical module 20, backboard 10 and bracket 30, wherein the optical module 20
The bottom is diffuser plate, and the bracket 30 is fixed on the backboard 10, is used to support the diffuser plate to including described
Optical module 20 including diffuser plate forms supporting role.
The structure of the bracket 30 is as shown in Figure 3 and Figure 4, which includes pedestal 31, support column 32 and elastic suspended
Arm 33, wherein the pedestal 31 is fixed on the backboard 10 and which is provided with the through slot 34 being connected to the backboard 10, institute
The one end for stating support column 32 is fixed on the through slot 34 by the elastic cantilever 33, and the other end of the support column 32 is logical
It crosses the diffuser plate to contact with the optical module 20, be supported with being formed to the optical module 20.
In this way, the through slot 34 being set on the pedestal 31 can make between the pedestal 31 and the backboard 10
Dashpot corresponding with the support column 32,33 position of the elastic cantilever is formed, thus in direct-light-type backlight 100
Optical module 20 forms protection, to reduce there is the liquid crystal display of the direct-light-type backlight 100 to be occurred after transport
The probability of the improper display situation such as blackening.
Liquid crystal display with above-mentioned direct-light-type backlight 100 during transportation, when its backboard 10 deforms
And drive the pedestal 31 of the bracket 30 towards the optical module 20 diffuser plate movement when, abutted with the diffuser plate described in
Support column 32 will receive the resistance of the diffuser plate, and at this time due to the presence of the dashpot, the support column 32 will drive
The elastic cantilever 33 is moved towards the direction of the dashpot, in this way, the support column 32 not only will not be with the pedestal 31
It moves towards the diffuser plate to oppress the diffuser plate, and the elastic cantilever 33 can also make the end of the support column 32
It is abutted always with diffuser plate holding in the process, to guarantee that the bracket 30 is not easy to squeeze because the backboard 10 deforms
The diffuser plate is pressed, it is impaired to avoid optical module 20, to reduce liquid crystal display occurred blackening etc. after transport
The probability of improper display situation.
The dashpot provides space for the scope of activities of the support column 32, can be in several ways in setting.
For example, concave surface 11 corresponding with 34 position of through slot can be set on the backboard 10, and the concave surface 11 leads to described
The dashpot, and the dashpot being arranged using such mode can be formed between slot 34, can give the through slot 34 and institute
Stating elastic cantilever 33, more assembly selection, the i.e. presence due to the concave surface 11 can expand the elastic cantilever 33 in institute
State the rigging position in through slot 34.Certainly, in another embodiment, it is also contemplated that being not provided with the concave surface 11, but improve
Rigging position of the elastic cantilever 33 in the through slot 34, so that the bottom of the elastic cantilever 33 and the through slot 34
Slot bottom between there are gaps to form the dashpot.And in another embodiment, the adjustable elastic cantilever 33
Position, so that the concave surface 11 can independently form the dashpot.
In order to form good support force and twisting resistance to the support column 32, in bracket 30 shown in Fig. 5, the bullet
Property cantilever 33 quantity be 4, and be intervally arranged in a ring along the cell wall of the through slot 34, and the one of each elastic cantilever 33
End is connected with the cell wall of the corresponding through slot 34, encloses installing zone between the other end of each elastic cantilever 33,
And the installing zone is the middle part positioned at the through slot 34, and the support column 32 be set to the installing zone and with it is corresponding each
The other end of the elastic cantilever 33 connects.Above-mentioned setting can not only make the support column 32 during up and down motion
Its stress equalization everywhere, and each elastic cantilever 33 it can be provided when rotation occurs for the support column 32 one it is anti-
To twisting resistance, be adjusted with the movement at any time to 32 various aspects of support column, to further decrease in liquid crystal display
The influence that the state of the bracket 30 is generated because backboard 10 deforms in transportational process.
It is understood that the quantity of the elastic cantilever 33 can be not limited to 4, and specific amount of setting can root
It is adjusted according to actual needs.For example, quantity 1 of the elastic cantilever 33 can be made, and keep the elastic cantilever 33 horizontal
Across the through slot 34 and its both ends is connect with the cell wall of the through slot 34 respectively, and if the elastic cantilever 33 of the setting its shape
Or construction setting is rationally, can not only guarantee the bracket 30 will not because backboard 10 deformation due to keep the optical module 20 impaired,
But also certain cost can be saved, therefore, in the quantity setting of elastic cantilever 33, bullet shown in fig. 5 can be not only restricted to
Property cantilever 33.In addition, elastic cantilever 33 can be as shown in Figure 5 be horizontally disposed on set-up mode, naturally it is also possible to be arranged
For other angles.
As shown in figure 5, each elastic cantilever 33 is S-shaped, which can be improved the bullet of the elastic cantilever 33
Property power, and the setting it is also assumed that be with the quantity of the elastic cantilever 33 cooperate so that the elastic cantilever 33 reaches one
It is a to be preferably arranged.Certainly, the elastic cantilever 33 can also be arranged to snakelike Deng curved shapes, or be arranged to linearly,
Specific setting determines according to the actual situation.
The pedestal 31 is assembled and disassembled on the backboard 10 for convenience, and enhances the pedestal 31 and the backboard 10
Bonding strength in bracket 30 shown in Fig. 5, is set on pedestal 31 there are two mounting hole 35, and the two described mounting holes 35
Around the through slot 34 in being intervally arranged, it is therefore possible to use the connectors such as screw pass through the mounting hole 35, by the bottom
Seat 31 is securely fastened on the backboard 10.
And preferably, above-mentioned bracket 30 can be the integral structure formed using injection molding or other techniques, even if described
Pedestal 31, the support column 32 and the elastic cantilever 33 are integrally formed, to can not only reduce production cost, Er Qieke
To improve the bonding strength between each component.
In addition, the support column 32 can be cone as shown in Figure 5, wherein the cone bottom of the support column 32 is fixed
In on the elastic cantilever 33, and the vertex of a cone of the support column 32 is contacted with the optical module 20, so that the support
Column 32 itself has stable structure, to form more stable support force to the optical module 20.It is of course also possible to be it
His shape.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
