DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figures 1 to 8 As shown, a computer performance testing device according to the present invention comprises a base 1; two columns 11 are fixedly connected to the top of the base 1; and mounting plates 12 are mounted above the two columns 11; A rotating disk 13 is provided on the opposite side of the two mounting disks 12, and the rotating disks 13 rotate on the adjacent mounting disks 12; a first motor 14 is fixedly connected to the mounting disks 12, and the first motor 14 is used to drive the mounting disks 12; The upper and lower sides of the two rotating disks 13 are fixedly connected to two opposite L-shaped plates 15; a first convex groove 16 is provided on the rotating disk 13 between the two L-shaped plates 15; the end surfaces of the two L-shaped plates 15 on the rotating disk 13 on the opposite sides are fixedly connected to the electric push rod 17, and the extension rods of the electric push rod 17 extend to the opposite side of the two L-shaped plates 15; Two clamping assemblies are arranged between the two rotating disks 13, and the clamping assemblies include a first clamping assembly 2 and a second clamping assembly 21; the two clamping assemblies each include two clamping plates 22, and the clamping plates 22 are located between the two rotating disks 13; each clamping plate 22 is provided with an extension plate 23 on two end surfaces close to the two rotating disks 13; and the extension plates 23 are provided with a threaded groove; Two U-shaped plates 24 are provided on opposite sides of the two L-shaped plates 15 on the two rotating disks 13, and two extension plates 23 close to the U-shaped plates 24 extend into the opposite U-shaped plates 24; a threaded rod 25 is rotatably connected in each of the U-shaped plates 24, and the threaded rod 25 has a midline as a dividing line, and the threads on both sides of the dividing line are opposite; The threaded rods 25 pass through the threaded grooves on the two extension plates 23, and the threaded rods 25 are driven by the second motor 26; the U-shaped plates 24 are fixedly connected to the first convex blocks 27 on one side close to the turntable 13, and the first convex blocks 27 slide in the first convex grooves 16; each of the U-shaped plates 24 is fixedly connected to the adjacent electric push rods 17; Specifically, when performing a vertical drop test on the laptop computer 18, first hold the laptop computer 18 and place the laptop computer 18 between the two clamping plates 22 on the two clamping assemblies, then control the second motor 26 to rotate in the forward direction, the second motor 26 will drive the threaded rod 25 to rotate, because the threaded rod 25 passes through the thread groove of the extension plate 23, it will drive the two extension plates 23 to approach each other, and at the same time, it will drive the two clamping plates 22 on the two clamping assemblies to approach each other, so that the laptop computer 18 can be clamped in the two clamping plates 22 on the two clamping assemblies, then control the second motor 26 to rotate in the reverse direction, when the second motor 26 rotates in the reverse direction, it will indirectly drive the two clamping plates 22 on the two clamping assemblies to move away from each other quickly, so that the laptop computer 18 is no longer clamped, and at this time the laptop computer 18 will fall freely under its own gravity, so that the laptop computer 18 is subjected to a vertical drop test; More specifically, when performing a horizontal drop test on the laptop computer 18, the laptop computer 18 is firstly clamped vertically in the two clamping plates 22 of the two clamping assemblies, and then the first motor 14 is controlled to rotate, the first motor 14 will drive the turntable 13 to rotate ninety degrees, and at the same time the turntable 13 will drive the L-shaped plate 15, the electric push rod 17, the U-shaped plate 24, the threaded rod 25, the second motor 26, the extension plate 23, the clamping plate 22 and the laptop computer 18 to rotate ninety degrees. After rotating ninety degrees, the electric push rod 17 is parallel to the base 1, the threaded rod 25 is perpendicular to the base 1, and the laptop computer 18 is in a horizontal state. Then the second motor 26 is reversed, and the second motor 26 is reversed. During the reversal of the second motor 26, the two clamping plates 22 on the two clamping assemblies will be indirectly driven to move away from each other. When the two clamping plates 22 on the two clamping assemblies move away from each other, the clamping plates 22 no longer clamp the laptop computer 18. Then the electric push rod 17 is controlled to shrink rapidly. During the shrinkage of the electric push rod 17, the U-shaped plate 24 will be pulled away from each other. At the same time, the U-shaped plate 24 will drive the two clamping assemblies to move away from each other. When the clamping plates 22 on the two clamping assemblies are separated from the laptop computer 18, the laptop computer 18 will fall from the gap between the two clamping assemblies under its own gravity, thereby performing a drop test on the laptop computer 18 in the horizontal direction. Further, when the laptop computer 18 is clamped on the two clamping assemblies, the first motor 14 can be controlled to drive the turntable 13 to rotate within a range of zero to ninety degrees, thereby driving the laptop computer 18 to tilt within a range of zero to ninety degrees. Within this angle range, the laptop computer 18 can be drop tested. When the laptop computer 18 is tested at a certain angle, the two clamping plates 22 on the two clamping assemblies are controlled to move away from each other, so that the laptop computer 18 is no longer clamped, and then the laptop computer 18 falls downward at a set angle, so that the laptop computer 18 can be drop tested at different tilt angles. Furthermore, by controlling the rotation of the turntable 13, the turntable 13 will drive the two clamping components to rotate, and the clamping components will drive the clamped laptop computer 18 to rotate. After rotation, the laptop computer 18 can not only perform a drop test in the vertical direction, but also a drop test in the horizontal direction. At the same time, the laptop computer 18 can be controlled to perform a drop test at different inclination angles within the range of zero to ninety degrees, thereby simulating the falling state of the laptop computer 18 under different circumstances, thereby improving the diversity of the laptop computer 18 test.

[0019] Embodiment 2: The column 11 is a hydraulic cylinder, and the column 11 rotates on the mounting plate 12 via a rotating shaft; Each of the clamping plates 22 has slideways on both sides, and the extension plates 23 slide in the slideways; Specifically, during the drop test of the laptop computer 18, one of the hydraulic cylinders can be controlled to extend. During the extension of the hydraulic cylinder, one of the mounting plates 12 and the turntable 13 will be driven to move upward, and the rising mounting plate 12 will rotate along the extended hydraulic cylinder. During the upward movement of the turntable 13, the two clamping assemblies will be driven to rotate with the other turntable 13 and the mounting plate 12, and the mounting plate 12 will rotate along the unextended hydraulic cylinder. In order to adapt to the distance between the two turntables 13, the rising U-shaped plate 24 will pull the extension plate 23 out of the clamp plate 22, thereby preventing the clamp plate 22 and the extension plate 23 from being fixed, causing the hydraulic cylinder to be unable to drive the mounting plate 12 and the turntable 13 on one side to rotate. When the two clamping assemblies present a certain tilt angle, a vertical drop test, a horizontal drop test, and a drop test of the laptop computer 18 at different tilt angles within the range of zero to ninety degrees can be performed on the basis of the tilt of the two clamping assemblies, thereby further simulating the falling state of the laptop computer 18 under different conditions, thereby improving the diversity of the drop test of the laptop computer 18.

[0020] Embodiment 3: The bottom of the two clamping plates 22 on the second clamping assembly 21 is provided with a support plate 3, and the support plate 3 is fixedly connected to the clamping plates 22 on the second clamping assembly 21 through evenly arranged connecting rods; In this embodiment, the connecting rod includes a fixed tube 31 and a sliding rod 32, wherein the fixed tube 31 is fixedly connected to the bottom of the clamping plate 22; the sliding rod 32 is fixedly connected to the support plate 3, and the sliding rod 32 slides in the fixed tube 31; a threaded hole is provided on the fixed tube 31, and the thread in the threaded hole engages with a locking bolt 33, and the fixed tube 31 and the sliding rod 32 are locked and fixed by the locking bolt 33; In this embodiment, the end surfaces of the two clamping plates 22 on the second clamping assembly 21 on opposite sides are each provided with a second convex groove 34; Two second convex blocks 35 are slidably disposed in the second convex grooves 34 ; a stopper 36 is mounted on each of the second convex blocks 35 , and the distance between the two stoppers 36 on the same clamping plate 22 is slightly greater than the length of the laptop computer 18 ; In this embodiment, each of the stoppers 36 is provided with a countersunk hole; a hexagon socket bolt 37 is provided in the countersunk hole; each of the second convex blocks 35 is provided with a thread groove, and the hexagon socket bolt 37 is threadedly engaged with the thread groove; Specifically, since the bottom of the two clamping plates 22 on the second clamping assembly 21 is provided with a support plate 3, when placing the laptop computer 18, the laptop computer 18 is first placed on one of the support plates 3, and then the two clamping plates 22 on the two clamping assemblies are controlled to approach each other, so that the laptop computer 18 is clamped in the two clamping assemblies. When the laptop computer 18 is clamped, the two support plates 3 are not in contact with each other. In this process, by providing the support plate 3, the laptop computer 18 can be prevented from being in a tilted state during the placement of the laptop computer 18; since the two clamping plates 22 on the second clamping assembly 21 are provided with stoppers 36 on the opposite sides, when placing the laptop computer 18, the laptop computer 18 is passed between the two stoppers 36, so that the laptop computer 18 can be limited and placed in the middle of the clamping plates 22; More specifically, when it is necessary to perform a drop test on laptop computers 18 of different specifications, the locking bolt 33 is loosened at this time, and the distance between the support plate 3 and the clamping plate 22 is adjusted according to the width of the laptop computer 18. During adjustment, the support plate 3 will drive the sliding rod 32 to move upward or downward in the fixing tube 31. When the distance adjustment is completed, the locking bolt 33 is tightened again, so that the sliding rod 32 can be pressed tightly against the fixing tube 31; then the hexagonal wrench is used to loosen the hexagonal bolt 37. After the hexagonal bolt 37 is loosened, the stopper 36 is pushed to move according to the length of the laptop computer 18. The stopper 36 will drive the second convex block 35 to move in the second convex groove 34. When the distance between the two stoppers 36 is adjusted, the stopper 36 can be locked with the hexagonal bolt 37.

[0021] Embodiment 4: The bottom of the two clamping plates 22 on the first clamping assembly 2 is provided with a limiting groove 28, and the cross section of the limiting groove 28 is a quarter circle; the two limiting grooves 28 are fixedly connected with a rubber layer; the upper surfaces of the two support plates 3 are also fixedly connected with a rubber layer; Specifically, when it is necessary to perform a drop test on the unfolded laptop computer 18, firstly, the two clamping plates 22 on the two clamping assemblies are controlled to move away from each other, then the laptop computer 18 is unfolded, and the two sides of the unfolded laptop computer 18 are placed on the two support plates 3 respectively. At this time, the distance between the two clamping plates 22 can be controlled according to the angle at which the laptop computer 18 needs to be unfolded. When the laptop computer 18 is placed on the two support plates 3, the two clamping plates 22 on the first clamping assembly 2 are controlled to move closer to each other until they fit together. When the two clamping plates 22 on the first clamping assembly 2 fit together, the two limiting grooves 28 form a semicircular groove. Then, the electric push rod 17 fixedly connected to the first clamping assembly 2 is controlled to extend. The electric push rod 17 extends When the first clamping assembly 2 is long, the first clamping assembly 2 will be driven to move downward as a whole, thereby driving the two mutually attached clamping plates 22 on the first clamping assembly 2 to move downward. In the process of the two attached clamping plates 22 moving downward, they will gradually approach the rotation axis of the laptop computer 18. When the rotation axis of the laptop computer 18 extends into the two limit grooves 28, the unfolded laptop computer 18 will be restricted on the two limit assemblies. Subsequently, a vertical drop test, a horizontal drop test, and a drop test of the laptop computer 18 at different tilt angles within the range of zero to ninety degrees can be performed on the basis of the unfolding of the laptop computer 18, thereby further simulating the falling state of the laptop computer 18 under different conditions, and improving the diversity of the drop test of the laptop computer 18. More specifically, since the rubber layer is fixedly connected to the limiting groove 28 and the support plate 3, when the unfolded laptop computer 18 is limited on the two limiting components, the rubber layer can prevent the limiting groove 28 and the support plate 3 from directly contacting the laptop computer 18, thereby causing damage to the laptop computer 18.
