Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, providing a kind of cell phone back light source glue frame that thermal diffusivity can be improved, including outline border 1, four in embodiment
A corner protector block 3, two the first radiating pieces 41, two the second radiating pieces 42, inside casings 2, outline border 1 are configured to rectangle frame, four corner protectors
Block 3 is individually fixed at four ends angle of outline border 1, two the first radiating pieces 41 respectively it is horizontal be fixed on the outer roof of outline border 1 with
And exterior bottom wall, and the both ends of two the first radiating pieces 41 are fixedly connected with adjacent corner protector block 3, two the second radiating pieces 42 divide
Be not fixed on the left side wall and right side wall of outline border 1 vertically, and the both ends of two the second radiating pieces 42 respectively with adjacent corner protector
Block 3 is fixedly connected, and inside casing 2 is located in frame composed by outline border 1, by multiple between the inner wall of outline border 1 and the outer wall of inside casing 2
Radiating block 51 connects, and the first through hole for heat dissipation is offered on radiating block 51, and small middle ball-handling 52 is filled in first through hole,
Small 52 inside of middle ball-handling is filled with silicon oxide powder.Outline border 1, inside casing 2 are all made of polycarbonate material and are made, and are starting to make
Used time, the backlight module of mobile phone are installed on inside casing 2, and backlight module can generate heat in the normal course of work, and heat can be from back
It is passed in optical module on inside casing 2, since radiating block 51 of ceramic fibre material by being made, set between inside casing 2 and outline border 1
Heat can be absorbed in the radiating block 51 set, thus heat is siphoned away from inside casing 2, the small middle ball-handling 52 in radiating block 51, by
In being filled with silicon oxide powder in ball, silicon oxide powder has good heat absorption capacity, the heat on inside casing 2 can be absorbed, and
Heat on inside casing 2 is from the backlight module of mobile phone, therefore radiating block 51 and small middle ball-handling 52 are i.e. from backlight mould
Draw heat in block.After radiating block 51 absorbs heat, heat is transmitted to again on outline border 1, first fixed on the outside of outline border 1
Radiating piece 41, the second radiating piece 42 can accelerate the heat absorption on outline border 1, since the two radiating pieces are arranged in outline border
1 outside, therefore very heat can shed well.And the corner protector block 3 at 4 ends angle of outline border 1 is set, work as glue frame
When colliding, hold the corner protector block 3 at angle that can serve as the position collided at first, since it is constituted using softer material,
Therefore most collision impact can be buffered, collision suffered by glue frame can be mitigated.

Obtain the preponderance of mobile phone.
In order to guarantee that enough silica can be accommodated in small middle ball-handling 52, further, the grain of silicon oxide powder
Diameter is not more than 100um.When the silicon oxide powder partial size of setting is sufficiently small, so that it may be filled with more powder in ball, lead
Hot property can also play best.
In order to reinforce the heat dissipation performance of outline border 1, further, offered on outline border 1 multiple through 1 rear and front end face of outline border
The second through-hole, filled with the aluminium block for heat dissipation in the second through-hole.Aluminium have good heating conduction, while its weight also compared with
Gently, the weight of glue frame will not be aggravated, therefore compares and is suitable for radiating here.
In order to carry out bradyseism well, further, corner protector block 3 is configured to L-type block, and corner protector block 3 is made of rubber material.
It is bonded at corner protector block 3 and the end angle of outline border 1, and rubber has good elasticity, while lighter weight, can satisfy and uses here
Make the needs of glue frame bradyseism.
In order to improve heat dissipation effect, further, radiating block 51 is made of ceramic fibre material.Ceramic fibre is a kind of fibre
Shape lightweight refracrory is tieed up, light-weight, thermal stability is good, can be used for carrying out heat absorption here.
In order to enable glue frame can be bonded well, further, pass through between radiating block 51 and outline border 1, inside casing 2
The bonding of PUR hot melt adhesive.PUR hot melt adhesive it is heat-resist, relatively good bonding can be also maintained in the higher situation of temperature
Power guarantees not falling out between component.
