DETAILED DESCRIPTION

[0024] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The following embodiments of the present invention will be described in conjunction with the accompanying drawings.

[0025] like Figure 1 、 Figure 2 and Figure 3As shown, a flexible soft screen folding tester includes a base and two groups of clamping components, the two groups of clamping components are relatively arranged on the base 1, and are used to relatively clamp and fix the two ends of the flexible soft screen 00; the two groups of clamping components are respectively connected to two flipping components, and the flipping components are used to drive the clamping device to swing up and down; the two flipping components are relatively arranged on the base 1, and the flexible soft screen 00 is arranged between the two groups of clamping components and the two flipping components. The two ends of the flexible soft screen 00 are driven to fold by the flipping components, which can realize a single-sided folding angle of 0-180° for the flexible soft screen 00, and the sum of the double-sided folding angles can also meet 0-180°, which can truly simulate the usage scenario of the flexible soft screen.

[0026] In a specific embodiment of the present invention, Figure 2 As shown, the clamping assembly includes an L-shaped flap 2, which includes a connecting section 21 and a pressing section 22 vertically connected thereto. The end of the connecting section 21 is connected to the flip component. A support plate 3 is provided at the bottom of the pressing section 22. The support plate 3 is L-shaped, and the horizontal portion of the support plate 3 is arranged at the bottom of the pressing section 22. The vertical portion of the support plate 3 is arranged on the outside of the pressing section 22. The two end edges of the flexible soft screen 00 can be fixed between the pressing section 22 and the support plate 3. The L-shaped flaps 2 of the two sets of clamping assemblies are arranged relative to each other and can be enclosed to form a rectangular area that matches the flexible soft screen 00. When in use, the protruding edges at both ends of the flexible soft screen 00 are fixed between the pressing section 22 and the support plate 3. Before folding, the flexible soft screen 00 is in a horizontal state. After folding, the sum of the single-side or double-side angles can achieve a folding of 0-180°.

[0027] As a preferred structure, Figure 3 、 4 As shown, the inner edge of the connecting section 21 is provided with an upright baffle 4 for limiting the two side edges of the flexible soft screen 00. The upper and lower ends of the baffle 4 are provided with guide portions 40 inclined toward the outside. With the help of the guide portions 40, the flexible soft screen 00 can smoothly enter between the two side baffles 4, avoiding the upper and lower edges from interfering with the smooth passage of the flexible soft screen 00.

[0028] Further optimize the above structure, such as Figure 2As shown, the connecting section 21 is a telescopic structure, including a movable portion 211 and a fixed portion 212. The movable portion 211 is provided with a plurality of positioning holes 210, and the fixed portion 212 is provided with connecting holes corresponding to the positioning holes 210. The positioning holes 210 and the connecting holes can be connected by fastening bolts. A clamping plate 20 is provided on the outer side of the fixed portion 212, and the clamping plate 20 is connected to the flip component. The pressing section 22 is provided with a plurality of limiting holes 220, and the support plate 3 is provided with fixing holes on the horizontal portion corresponding to the limiting holes 220. During production, a step is provided in the middle of the fixed portion 212 to cooperate with the movable portion 211. When adjusting the size of the L-shaped flap 2, the movable portion 211 can move along the bottom surface of the step, facilitating the rapid alignment of the positioning holes 210 with the connecting holes on the fixed portion 212. The pressing section 22 slides directly at a right angle along the inner side of the support plate 3 to quickly align the limiting holes 220 with the fixing holes on the support plate 3. The L-shaped flap 2 with the above structure can be applied to flexible soft screens 00 of different specifications and sizes.

[0029] In a specific embodiment of the present invention, Figure 1 、 3 As shown, the flip component includes a motor 5 and a reducer 6. The output end of the motor 5 is connected to the input end of the reducer 6, and the output shaft of the reducer 6 is connected to the connecting section 21 of the L-shaped flap 2. The motor 5 and reducer 6 are externally provided with protective shields. The external shields of the two flip components are respectively a first shield 7 and a second shield 8. The output shafts of the two reducers 6 are respectively located in the middle of the side walls opposite the first shield 7 and the second shield 8, and extend through the side walls to connect to the connecting section 21 of the L-shaped flap 2. The protective shields protect the motor and reducer, preventing safety accidents and increasing the safety factor during the test.

[0030] When designing specifically, Figure 3 As shown, a motor 5 and a reducer 6 are arranged in the first protective cover 7, and another motor 5 and a reducer 6 are arranged in the second protective cover 8. A servo drive 9 connected to the motor 5 is also provided. A power socket 10 and a fan 11 are provided on the side of the second protective cover 8, and a control panel 12 and control buttons 13 are provided on the front. The servo drive 9 is electrically connected to the power socket 10, the control panel 12 and the control buttons 13. The servo drive 9 can realize the forward and reverse rotation of the motor 5, meeting the test requirements of the foldable flexible soft screen 00. At the same time, the control panel can adopt a touch screen, which facilitates the control of the start and stop of the motor 5 on the control panel.

[0031] Further optimize the above scheme, such as Figure 2As shown, two limit posts 16 and two photoelectric switches 14 are provided on opposite sides of the first protective cover 7 and the second protective cover 8, respectively. The two limit posts 16 and two photoelectric switches 14 on the same side are horizontally symmetrically arranged on both sides of the output end of the reducer 6 on the same side, and are respectively used to limit the stroke of the L-shaped flap 2 and sense the number of times the L-shaped flap 2 has been folded; the photoelectric switch 14 is connected to the control panel 12. The number of times the flexible soft screen 00 has been folded can be displayed on the control panel through the photoelectric switch. At the same time, a mechanical travel switch can be installed on the top of the limit post 16, and the mechanical travel switch can be linked to the motor to prevent the L-shaped flap 2 from colliding with the limit post 16 under the action of inertia.

[0032] In specific applications, such as Figure 1 As shown, the bottom of the base 1 is provided with a plurality of adjustment legs 15 for adjusting the levelness of the base 1. Before use, the base 1 is adjusted to a level by adjusting the legs 15, and then the folding test is started to improve the test accuracy.

[0033] To sum up, the utility model has the advantages of simple structure and high test accuracy. The two ends of the flexible soft screen 00 are clamped and fixed by using the L-shaped flap 2. Starting the motor 5 can make the pressing section of the L-shaped flap 2 swing up and down, thereby driving the flexible soft screen 00 to fold back and forth, realizing the folding of the flexible soft screen 00 between 0-180°, and can truly simulate the usage scenario of the flexible soft screen, and meet the bending resistance characteristic test requirements of the flexible soft screen.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
