Embodiment, broadly falls into the scope of protection of the invention.
As depicted in figs. 1 and 2, a kind of bending test apparatus that the embodiment of the present invention provides, for carrying out curved to flexible screen
Folding test, including board 1, board 1 is provided with first and fixes end 5, also includes bracing frame 2 and bending axle 3, and bending axle 3 is installed
On board 1, bending axle 3 includes the bending cambered surface that multiple radius is different, matches for the bending part treating multiple flexible screen
Conjunction carries out bending test, and bracing frame 2 is provided with end 5 relative second fixing with first on board 1 and fixes end 6, for by one
End be fixed on board 1 first fix end 5 and bending cambered surface and board 1 towards bending cambered surface one side between soft
Property screen is fixed on bracing frame 2, and bracing frame 2 is arranged on board 1, and bracing frame 2 can the axial line of described bending axle 3 be axle
Turn down to carry out flexible screen bending test relative to board 1.
In above-mentioned bending test apparatus, one end of flexible screen to be tested is fixed on the fixing end of first on board 1
5, flexible screen is fixed on second on bracing frame 2 through bending cambered surface and board 1 towards the gap the one side of bending cambered surface
Fixing end 6, when carrying out bending test, flexible screen turns down to carry out flexible screen bending with the relative board 1 of bracing frame 2 and surveys
Examination, owing to bending axle 3 includes the bending cambered surface that multiple radius is different so that multiple flexible screen can be entered by this bending test apparatus
The bending test of the different crooked process radius of row, each flexible screen is corresponding with a bending cambered surface.
Therefore, above-mentioned bending test apparatus can carry out the test of multiple flexible screen multiple crooked process radius, improves testing efficiency.
In a kind of preferred implementation, bending axle 3 is multidiameter, and multidiameter includes at least one cascaded surface.Bending axle 3 can
Thinking that multidiameter, multidiameter have multiple cascaded surface, the radius of two axles that each cascaded surface correspondence is connected is different, corresponding to not
Same crooked process radius, therefore the test of flexible screen difference crooked process radius can be carried out.
In a kind of preferred implementation, bending axle 3 includes multiple removably connecting and concentric cylinder that radius is different.Specifically
Ground, one end of each cylinder is provided with connecting rod, and the other end is provided with connecting hole, the connecting rod of cylinder and adjacent pitch cylinder one end
Connecting hole is in mating connection, and the connecting hole of the other end is in mating connection with the connecting rod of another pitch cylinder one end adjacent.
Bending axle 3 is disassembled structure, and the concentric cylinder different by multiple radiuses forms, and each cylinder can be by connecting
