DETAILED DESCRIPTION
[0030] like Figures 1 to 9 As shown, the present invention is a flip tablet durability testing device, the flip tablet includes a main panel 1, a cover plate 2 connected to the main panel 1, a damping hinge is arranged between the main panel 1 and the cover plate 2, the damping hinge is used to generate a certain damping between the cover plate 2 and the main panel 1 when they are closed, so as to avoid damage to the equipment caused by impact caused by excessive inertia when the two are closed.
[0031] Among them, the detection equipment includes a bottom bracket 3 for supporting the main panel 1 and a diagonal support bracket 4 connected to the bottom bracket 3. The bottom bracket 3 is placed horizontally on the workbench. A column 5 is fixed on the side of the bottom bracket 3 away from the diagonal support bracket 4. The column 5 extends vertically upward. A cylinder 6 is connected between the column 5 and the diagonal support bracket 4. The cylinder 6 is connected to a controller. The controller can be used for counting and can also control the cylinder 6 to extend and retract back and forth or be empty.
[0032] Specifically, the diagonal support bracket 4 is connected to a limit block 8 through an elastic connection component 7. A limit groove 9 for engaging the cover plate 2 is provided on the lower side of the limit block 8. The upper side of the cover plate 2 is installed in the limit groove 9. When the limit block 8 is turned over, the cover plate 2 can be driven to turn over together. A limit component 10 for limiting the turning limit position of the diagonal support bracket 4 is provided on the side of the bottom bracket 3. The limit component 10 can determine the disengagement position between the diagonal support bracket 4 and the cover plate 2; a plug 11 is fixed on the side of the limit block 8, and a plug 12 is provided on the upper side of the bottom bracket 3 corresponding to the plug 11. When the plug 11 is engaged with the plug 12, it means that the damping hinge fails during the test and the cover plate 2 is over-turned. At this time, the controller controls the cylinder 6 to stop and count.
[0033] In this embodiment, the diagonal support bracket 4 includes a U-shaped bracket 13, both ends of the U-shaped bracket 13 are hinged to the bottom bracket 3, and a crossbeam 14 is provided on the U-shaped bracket 13. The crossbeam 14 is rotatably connected to a rotating capsule 15, and the rotating capsule 15 is filled with gas. By providing the rotating capsule 15, the rotating capsule 15 has a buffering effect to prevent the cover plate 2 from being damaged when returning to its original position. By arranging the rotating capsule 15 in a rotating manner, it is also convenient to guide the cover plate 2 when it is inserted into the limiting groove 9, reducing the possibility of friction damage.
[0034] In this embodiment, a triangle plate 16 is fixed at the right angle of the U-shaped bracket 13, and the triangle plate 16 is parallel to the plane where the diagonal support bracket 4 is located. A screw rod 17 is threadedly connected to the triangle plate 16, and a first connecting buckle 18 is connected to the outer end of the screw rod 17. A second connecting buckle 19 is fixed to the column 5, and a limit pull rope 20 is connected between the first connecting buckle 18 and the second connecting buckle 19. The limit pull rope 20 can be used to limit the diagonal support bracket 4, prevent the diagonal support bracket 4 from excessively turning backward, and facilitate the control of the cylinder 6. By adjusting the length of the screw rod 17 penetrating into the inner side of the triangle plate 16, the limit angle of the diagonal support bracket 4 can be fine-tuned.
[0035] In this embodiment, the elastic connection component 7 includes a support 21, a rotating shaft 22, a coil spring 23, a fixed seat 24, a rotating wheel 25 and a pull belt 26. The support 21 and the fixed seat 24 are fixed on the inner side of the diagonal support bracket 4, the rotating shaft 22 is rotatably connected to the support 21, and the coil spring 23 and the rotating wheel 25 are coaxially connected to the rotating shaft 22. The outer end of the coil spring 23 is connected to the fixed seat 24, and the inner end of the coil spring 23 is fixedly connected to the rotating shaft 22. One end of the pull belt 26 is wrapped around the rotating wheel 25, and the other end of the pull belt 26 is connected to the limit block 8. When the cover 2 is separated from the diagonal support bracket 4, the cover 2 can pull the drawstring 26 to continue to move. At this time, the drawstring 26 at the end of the cover 2 can drive the rotating wheel 25 to rotate to continue to release the drawstring 26. The rotating wheel 25 drives the rotating shaft 22 to rotate. The rotating shaft 22 provides a resisting force through the coil spring 23. When the cover 2 rotates to a certain extent, the damping hinge consumes its energy and drives the cover 2 to stop. The cover 2 returns to its original position under the action of the coil spring 23, which is convenient for the next test cycle.
[0036] In this embodiment, a telescopic rod 27 is provided on one side of the U-shaped bracket 13, and the telescopic rod 27 extends outward along the lateral direction of the U-shaped bracket 13. The limiting assembly 10 includes a first telescopic device 28, which is fixed to the side of the bottom bracket 3. The output end of the bottom bracket 3 is connected to the limiting bracket 29, and a sliding column 30 is fixed on the limiting bracket 29. The side of the bottom bracket 3 is provided with a slide groove 31 for matching the slide column 30, and the slide groove 31 extends in the longitudinal direction. The first telescopic device 28 uses a hydraulic cylinder, which can drive the limiting bracket 29 to move longitudinally, and the end of the limiting bracket 29 is used to limit the telescopic rod 27. The limiting position of the limiting bracket 29 can be changed by the first telescopic device 28.
[0037] In this embodiment, the telescopic rod 27 is connected to the output end of the second telescopic device 32, and the second telescopic device 32 is fixed on the U-shaped bracket 13. When it is not necessary to limit the diagonal support bracket 4, the telescopic rod 27 can be retracted by the second telescopic device 32.
[0038] In this embodiment, the plug 11 includes a pillar 33 fixed to the end surface of the limit block 8, and a plurality of tongues 34 evenly distributed on the outer end of the pillar 33. The tongues 34 are evenly distributed along the circumference, and there is a gap between two adjacent tongues 34. The outer ends of the tongues 34 form a conical protrusion 35. A ring neck is formed on the inner side of the upper end of the insertion tube 12. When the plug 11 is matched with the insertion tube 12, the tongue 34 is squeezed into the insertion tube 12, and the conical protrusion 35 of the tongue 34 is prevented from coming out from the inner side of the insertion tube 12 by the limiting effect of the ring neck.
[0039] In this embodiment, a pressing plate 36 is connected to one of the columns 5, and a limiting seat 37 is fixed to the other column 5. One end of the pressing plate 36 is hinged to the column 5, and the other end of the pressing plate 36 is detachably connected to the limiting seat 37. The pressing plate 36 is made of elastic material, and the pressing plate 36 presses the main panel 1 against the bottom bracket 3. The shaking effect of the plane during the test can be reduced, and the test effect is more accurate.
[0040] In this embodiment, the bottom bracket 3 includes an outer frame 38, an inner frame 39 arranged inside the outer frame 38, and a connecting seat 40 connecting the outer frame 38 and the inner frame 39. A guide rail 41 is fixed inside the outer frame 38, and a guide groove 42 is provided on the upper side of the guide rail 41. A screw 43 is slidably arranged in the guide groove 42, and a slide seat 44 is connected to the screw 43. The slide seat 44 and the guide groove 42 are fastened by a nut 45, and the diagonal support bracket 4 is hinged to the slide seat 44. By sliding the screw 43, the position of the screw 43 on the guide rail 41 can be changed, thereby changing the hinge point position of the diagonal support bracket 4, which can meet the needs of products of different specifications.
[0041] Working principle description: Before starting the device, first install the tablet Figure 1 In the state shown, the main panel 1 is pressed by the pressure plate 36, and the upper end of the cover plate 2 is clamped by the limit block 8. At this time, the angle between the cover plate 2 and the main panel 1 is 120°. At this time, the controller controls the cylinder 6 to shrink instantly. When the diagonal support bracket 4 is limited by the limit assembly 10, the cylinder 6 is unloaded, and the cover plate 2 continues to flip under the action of inertia. Then the cover plate 2 gradually stops under the damping action of the damping hinge. After stopping, the cylinder 6 extends, and the limit block 8 can drive the cover plate 2 to return to its original position, which is convenient for the next flipping cycle. When the damping hinge of the flat plate is damaged, the cover plate 2 is no longer bound by the damping hinge. Under the action of inertia, the cover plate 2 covers the main panel 1 after breaking through the constraint of the elastic connection assembly 7. At this time, the cylinder 6 stops working, and the controller counts the durability times, which can facilitate the monitoring of the durability of the flat plate.
