Embodiment one
Fig. 2 is the structural schematic diagram of backlight module provided by the utility model, as shown in Fig. 2, present embodiments providing one
Kind backlight module, including light guide plate 2 and glue frame 1, glue frame 1 have accommodation space, and light guide plate 2 is located in accommodation space.Light guide plate 2
At least one angle on be provided with first lug 21, the position that glue frame 1 corresponds to first lug 21 offers the first locating slot 11,
First locating slot 11 has the notch of connection accommodation space, and first lug 21 is at least partially disposed in the first locating slot 11, and energy
It is moved along the direction close to or far from the notch, the first lug 21 is located at the part in first locating slot 11 most
Big width is greater than the width of the notch.By the way that first lug 21 is arranged on light guide plate 2, the first positioning is set in glue frame 1
Groove makes the limit of first lug 21 in the first positioning groove, effectively simplifies the installation process of backlight module, improves assembling effect
Rate reduces jig and material that assembling uses；It can make 2 expanded by heating of light guide plate or when by cold events, first lug 21 does not take off
From the first locating slot 11, the mounting stability and reliability of light guide plate 2 and glue frame 1 are improved, is conducive to the RA verifying of backlight module.
Specifically, as shown in Fig. 2, light guide plate 2 includes adjacent first side 22 and second side 23, first lug 21 is set
It sets between first side 22 and second side 23.First lug 21 includes the first guide edge 213 and the second guide edge 214, the
One guide edge 213 is connect with first side 22, and has the first default obtuse angle with first side 22.Second guide edge 214 and
Dual side-edge 23 connects, and has the second default obtuse angle with second side 23.
Glue frame 1 includes adjacent the first side wall 12 and second sidewall 13, and the first locating slot 11 is provided with 12 He of the first side wall
Between second sidewall 13, the first locating slot 11 includes the first cell wall 111 and the second cell wall 112 being oppositely arranged, the first cell wall 111
It is connect with the first side wall 12, and with the first side wall 12 there is third to preset obtuse angle；Second cell wall 112 is connect with second sidewall 13,
And there is the 4th default obtuse angle with second sidewall 13.
The setting at the first default obtuse angle and the second default obtuse angle makes the first guide edge 213 and the second guide edge 214 in first
Predetermined acute angle, to make the width of first lug 21 that the trend being gradually increased outward by light guide plate 2 be presented.First cell wall, 111 He
Second cell wall 112 is formed with the notch together with accommodation space, and third, which presets obtuse angle and the setting at the 4th default obtuse angle, makes the first slot
Wall 111 and the second cell wall 112 are in the second predetermined acute angle, to make the notch edge of the first locating slot 11 towards the direction of light guide plate 2
It gradually tapers up.
There is the first gap, the second guide edge 214 and the second cell wall 112 between first guide edge 213 and the first cell wall 111
Between have the second gap, between the first side wall 12 and first side 22 have third space, second sidewall 13 and second side
There is the 4th gap between 23.
Minimum widith between first guide edge 213 and the second guide edge 214 is less than the width of notch, the first guide edge
213 and the second maximum width between guide edge 214 be greater than the width of notch, enable first lug 21 in the first locating slot 11
It is movable by a small margin, and energy edge is moved towards or away from the direction of 11 notch of the first locating slot.And when first lug 21 is along far from slot
When the direction movement of mouth, the movement travel of first lug 21 is limited by the first side 22 of light guide plate 2 and second side 23；When
When one lug 21 is moved along the direction close to notch, first lug 21 is greater than slot due to protruding into the partial width of the first locating slot 11
The width of mouth, so that first lug 21 be made not to be detached from from the first locating slot 11.
That is, when light guide plate 2 at low ambient temperatures by cold events when, light guide plate 2 be cooled contraction drive 21 edge of first lug
The movement of accommodation space internal contraction, but not be detached from from the first locating slot 11；When the expanded by heating under high temperature environment of light guide plate 2
When, first lug 21 is moved along the direction far from accommodation space when the expanded by heating of light guide plate 2, and third space and the 4th gap

21 movement in the first locating slot 11 is oriented to and is limited.
In the present embodiment, the first gap is identical with the size in the second gap, and the processing for being conducive to the first locating slot 11 is set
Meter.And first gap and the second gap width be that 0.15mm-0.2mm subtracts while the deformation for first lug 21 provides space
The size of small first locating slot 11, is conducive to narrow frame design.In other embodiments, the first gap and can also be not provided with
Two gaps, when 21 expanded by heating of first lug, first lug 21 will receive the extruding of the first cell wall 111 and the second cell wall 112,
But due to the small volume of first lug 21, thinner thickness can be absorbed to power has been overstock and be deformed, thus will not
Expand to deformation on light guide plate 2, the influence to 2 optical quality of light guide plate is smaller.
In the present embodiment, third space and the 4th gap should according to the size of light guide plate 2 and coefficient of thermal expansion and contraction into
The specific design of row.
In the present embodiment, there are two first lugs 21 for setting on light guide plate 2, and two first lugs 21 are located at together
In the two corners of a side, be conducive to carry out more stable fixation in glue frame 1 to light guide plate 2.And
In the present embodiment, first side 22 is the side of light source of the light guide plate 2 far from backlight module, two second sides
23 are located at the two sides of first side 22, each setting of first lug 21 first side 22 and corresponding second side 23 it
Between angle on.
Fig. 3 is the partial schematic diagram at second side 23 provided in this embodiment, as shown in figure 3, in the present embodiment, being
Fixation of the light guide plate 2 in glue frame 1 is assisted, 23 convex of second side is equipped with the second lug 24, second sidewall 13 corresponding second
The position of lug 24 offers the second locating slot 14, and the second lug 24 is at least partially disposed in the second locating slot 14.Second lug
24 can be rectangle, can also be of similar shape with first lug 21, or any other shape.In this implementation
In example, 24 ground width value of the second lug is greater than 30mm, has the 5th gap between the second lug 24 and second sidewall 13, between the 5th
Gap value is 0.2mm-0.5mm, and the size of the second gap width should specifically be designed according to the length and width of the second lug 24,
When the length of the second lug 24 is bigger, deflection when expanded by heating is bigger, and the 5th gap width is bigger.
