Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0033] Example 1

[0034] One of the implementation methods of a folding screen hinge flip test device of the present application is used to test the flipping of a folding screen 4, wherein the folding screen 4 includes a first screen 41 and a second screen 42, such as Figures 1 to 4As shown, the folding screen hinge flip test device includes: a base 1, a rotating mechanism 2 and a clamping mechanism 3 arranged on the base 1, and a locking mechanism 5 and a positioning mechanism 6 arranged on the rotating mechanism 2.

[0035] The locking mechanism 5 is used to fix the first screen 41; the clamping mechanism 3 is used to fix the second screen 42; the positioning mechanism 6 is used to provide an axis reference point for the rotation axis position of the folding screen 4; the rotating mechanism 2 is used to drive the locking mechanism 5 to rotate, so that the first screen 41 and the second screen 42 can be switched between the folded and unfolded states.

[0036] Specifically, the clamping mechanism 3 includes a slide 31 and a clamping hand 34 disposed on the slide 31. The clamping hand 34 is used to limit the second screen 42, and the single-side clearance between the clamping hand 34 and the second screen 42 is 0.1MM.

[0037] In this embodiment, a first adjustment seat 32 is also fixed on the slide seat 31; the clamp 34 is fixed on the first mounting plate 33; the first adjustment seat 32 is used to fix the first mounting plate 33. When practical, the installation position of the first mounting plate 33 on the first adjustment seat 32 can be adjusted according to actual needs to adjust the height of the clamp 34.

[0038] The locking mechanism includes a second mounting plate 51, a locking assembly 52, an upper fastening block 53, a lower fastening block 54 and a side fastening block 55; the upper fastening block 53, the lower fastening block 54, the locking assembly 52 and the side fastening block 55 are all arranged on the second mounting plate 51, wherein the side fastening block 55 is arranged on one side of the second mounting plate 51, and the locking assembly 52 is connected to the upper fastening block 53; the upper fastening block 53 and the lower fastening block 54 are used to abut against both ends of the first screen 41.

[0039] A folding screen hinge flip test device applied in the present application can test the performance of each section of different chain assembly, and detect defects in the hinge in the front section assembly; it greatly reduces the defects such as jamming, abnormal noise, incomplete closure or loose parts in the finished hinge.

[0040] Specifically, the upper fastening block 53 and the lower fastening block 54 are both provided with a slot that matches the slot of the first screen 41 to prevent the first screen 41 from shaking left and right during the rotation movement. When in use, for different hinge tests, only the corresponding upper fastening block 53 and lower fastening block 54 need to be replaced.

[0041] More specifically, the locking assembly 52 includes a locking switch 523, a compacting column 521, a compacting block 522, a guide column 524 and a limit block 525; the locking switch 523 is connected to one end of the compacting block 522 through the compacting column 521, and the other end of the compacting block 522 is fixedly connected to the upper fastening block 53. The limit block 525 is fixedly arranged on the second mounting plate 51, and the guide column 524 is connected to the compacting block 522 after passing through the guide hole in the limit block 525. After the compacting block 522 is pressed down by the locking switch 523 so that the two ends of the first screen 41 abut against the upper fastening block 53 and the lower fastening block 54, the locking switch 523 locks the position of the compacting block 522 to prevent the first screen 41 from falling off during the rotation process.

[0042] The positioning mechanism 6 includes a positioning pin 621, a second adjustment seat 61 and a second mounting seat 62; the second adjustment seat 61 is fixed on the turntable 21, one end of the second mounting seat 62 is connected to the second adjustment seat 61, and the other end is provided with a positioning pin 621. The positioning pin 621 and the rotating shaft of the turntable 21 are arranged on the same axis, so that when the folding screen is installed, the rotating shaft of the folding screen and the rotating shaft of the turntable 21 can be accurately arranged on the same axis.

[0043] Furthermore, the slide seat 31 includes a first slide rail 313, a first slider 311, a second slide rail 314 and a second slider 315; the first slide rail 313 is fixed on the base 1, and the second slide rail 314 is fixed on the first slider 311; the first slider 311 is slidably connected with the first slide rail 313, and the second slider 315 is slidably connected with the second slide rail 314; the first adjustment seat 32 is fixed on the second slider 315. Among them, the corresponding moving directions of the first slide rail 313 and the second slide rail 314 are perpendicular to each other. When the rotating mechanism 2 drives the first screen 41 to rotate back and forth through the turntable 21, the first screen 41 flips back and forth relative to the second screen 42, and the second screen 42 drives the first adjustment seat 32 to move adaptively in the left and right and front and back directions, eliminating the error generated by the first screen 41 during rotation, and effectively avoiding damage to the hinge of the folding screen 4.

[0044] Specifically, the sliding seat 31 further includes a spring 3121 and a spring seat 312 fixed on the base 1 ; one end of the spring 3121 abuts against the first sliding block 311 , and the other end is fixedly connected or abutted against the spring seat 312 .
