Upper chase with clearance structure
Technical field
The utility model is related to LCM modular structure technical field of improvement, especially a kind of upper chase with clearance structure.
Background technology
The lower hem edge of chase is straight flange on existing LCM modules, causes LCM (Liquid Crystal Module) glass winding displacement to bend
During to the back side, the straight flange edge of the upper chase lower hem of glass winding displacement bending place extruding easily grinds the circuit of bending place glass winding displacement
Damage, cause LCM displays abnormal.
Therefore, to solve the above problems, needing to design a kind of upper chase for not producing friction with glass winding displacement bending place.
The content of the invention
Technical problem to be solved in the utility model is:A kind of band that friction is not produced with glass winding displacement bending place is provided
There is the upper chase of clearance structure.
The technical scheme that the utility model is used is:A kind of upper chase with clearance structure of offer, including chase are whole
Body, described chase integral edge has upper hem, lower hem, left folding in, right folding, described upper hem, lower hem, left folding
In, right folding, the panel overall with chase is connected at a right angle, it is characterised in that:The lower hem carries a clearance structure, described
Clearance structure is the rectangular indentation of lower hem edge.
The rectangular indentation edge of the clearance structure is circular arc or hypotenuse.
After above structure, the utility model can be by the rectangular indentation of clearance structure, it is to avoid upper chase lower hem
Edge and glass winding displacement bending place produce friction, further, the circular arc or hypotenuse at rectangular indentation edge also function to absorbed glass
Winding displacement bending place and the effect of upper chase side-friction, improve LCM module yields.

Embodiment
The utility model is described in detail below in conjunction with drawings and examples.
As shown in Figures 1 to 9, a kind of upper chase with clearance structure, including chase overall 1, the overall 1 edge tool of chase
Have upper hem 5, lower hem 6, left folding in 7, right folding 8, upper hem 5, lower hem 6, left folding in 7, right folding 8 with chase overall 1
Panel connect at a right angle, lower hem 6 carry a clearance structure 2, clearance structure 2 be the edge of lower hem 6 rectangular indentation.
The rectangular indentation edge of clearance structure 2 is circular arc 3 or hypotenuse 4.
Production process of the present utility model is as follows:
First pass through mould and be punched into chase base material profile(Such as Fig. 1), then with centre windowing mould upper chase base material is rushed
Go out clearance structure 2(Such as Fig. 2), finally upper chase base material flanging is molded using flanging mould(Such as Fig. 3).
