Description

Technical Field

[0001] The present invention belongs to the technical field of computer performance detection, and specifically relates to a computer performance detection device. Background Art

[0002] Before leaving the factory, laptop computers will undergo a series of strict quality tests to ensure their performance and reliability. These tests are mainly used to discover and fix any problems that may affect the user experience, including hardware failures, software compatibility, battery life, heat dissipation performance, and overall durability, etc.;

[0003] In order to evaluate the reliability and durability of laptop computers during long-term use, the drop test is a necessary test for laptop computers before leaving the factory. The laptop computer drop test is an important test to examine the anti-accidental impact ability and durability of laptop computers, mainly used to simulate the adaptability of laptop computers to resist drop impacts during handling, transportation, storage, and use, so as to ensure that they can still maintain a complete structure and normal functions under various possible accidental situations, such as simulating the conditions when a laptop computer falls from a desktop or is thrown out of a suitcase, etc.;

[0004] For existing drop test machines, when conducting a drop test on a laptop computer, the laptop computer is directly placed on the tray for testing, and the falling states of the laptop in different situations cannot be simulated. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve the above technical problems, the present invention proposes a computer performance detection device. By setting up the detection device, the falling states of laptop computers in different situations can be simulated. The specific structure is as follows;

[0006] A computer performance detection device includes a base; two columns are fixedly connected to the top of the base; mounting plates are installed above both of the two columns;

[0007] Rotary disks are provided on the opposite sides of both of the two mounting plates, and the rotary disks are respectively rotatably arranged on the adjacent mounting plates; a first motor is fixedly connected to the mounting plate, and the first motor is used to drive the mounting plate;

[0008] Two pairs of opposite L-shaped plates are fixedly connected to the upper and lower sides of both of the two rotary disks; a first convex groove is formed on the rotary disk between the two L-shaped plates; end faces on the opposite sides of the two L-shaped plates located on the rotary disk are fixedly connected with electric push rods, and the extending rods of the electric push rods all extend to the opposite sides of the two L-shaped plates;

[0009] There are two clamping assemblies between the two turntables. The clamping assemblies include a first clamping assembly and a second clamping assembly. Both of the two clamping assemblies include two clamping plates, and the clamping plates are located between the two turntables. On each of the two end faces of each clamping plate close to the two turntables, there are extension plates. Thread grooves are provided on the extension plates.

[0010] On the opposite sides of the two L-shaped plates on the two turntables, there are two U-shaped plates respectively. The two extension plates close to the U-shaped plates extend into the opposite U-shaped plates respectively. A threaded rod is rotatably connected in each U-shaped plate. Taking the midline as the demarcation line, the threads on both sides of the demarcation line are opposite.

[0011] The threaded rods all pass through the thread grooves on the two extension plates, and the threaded rods are driven by a second motor. On the side of each U-shaped plate close to the turntable, there is a first convex block fixedly connected, and the first convex block slides in the first convex groove. Each U-shaped plate is fixedly connected to the adjacent electric push rod.

[0012] Preferably, the column is a hydraulic cylinder, and the column rotates on the mounting plate through a rotating shaft.

[0013] On both sides of each clamping plate, there are slideways, and the extension plates slide in the slideways.

[0014] Preferably, on the bottoms of the two clamping plates of the second clamping assembly, there are support plates.

[0015] The support plates are fixedly connected to the clamping plates on the second clamping assembly through uniformly arranged connecting rods.

[0016] Preferably, the connecting rod includes a fixed cylinder and a sliding rod.

[0017] The fixed cylinder is fixedly connected to the bottom of the clamping plate. The sliding rod is fixedly connected to the support plate, and the sliding rod slides in the fixed cylinder. There is a threaded hole on the fixed cylinder, and a locking bolt is threadedly engaged in the threaded hole. The fixed cylinder and the sliding rod are locked and fixed through the locking bolt.

[0018] Preferably, on the opposite side end faces of the two clamping plates of the second clamping assembly, there are second convex grooves.

[0019] Two second convex blocks slide in the second convex grooves respectively. Blocks are installed on the second convex blocks, and the distance between the two blocks on the same clamping plate is slightly greater than the length of the laptop.

Specific embodiments

[0038] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0039] Embodiment 1: As Figures 1 to 8 shown, a computer performance detection device of the present invention includes a base 1; two columns 11 are fixedly connected to the top of the base 1; mounting plates 12 are installed above both of the two columns 11;

[0040] Rotating discs 13 are provided on the opposite sides of both of the two mounting plates 12, and the rotating discs 13 are respectively rotatable on the adjacent mounting plates 12; a first motor 14 is fixedly connected to the mounting plate 12, and the first motor 14 is used to drive the mounting plate 12;

[0041] Two pairs of opposite L-shaped plates 15 are fixedly connected to the upper and lower sides of both of the two rotating discs 13; a first convex groove 16 is formed on the rotating disc 13 between the two L-shaped plates 15; end faces on the opposite sides of the two L-shaped plates 15 located on the rotating disc 13 are fixedly connected with electric push rods 17, and the extension rods of the electric push rods 17 all extend to the opposite sides of the two L-shaped plates 15;

[0042] There are two clamping components provided between the two turntables 13. The clamping components include a first clamping component 2 and a second clamping component 21. Both of the two clamping components include two clamping plates 22, and the clamping plates 22 are located between the two turntables 13. On each of the two end faces of each clamping plate 22 close to the two turntables 13, there are extension plates 23 provided. Thread grooves are opened on the extension plates 23.

[0043] On the relative sides of the two L-shaped plates 15 on the two turntables 13, there are two U-shaped plates 24 provided. The two extension plates 23 close to the U-shaped plates 24 both extend into the opposite U-shaped plates 24. A threaded rod 25 is rotatably connected in each U-shaped plate 24, and taking the midline of the threaded rod 25 as the demarcation line, the threads on both sides of the demarcation line are opposite.

[0044] The threaded rods 25 all pass through the thread grooves on the two extension plates 23, and the threaded rods 25 are driven by a second motor 26. On the side of each U-shaped plate 24 close to the turntable 13, there is a first convex block 27 fixedly connected, and the first convex blocks 27 all slide in the first convex grooves 16. Each U-shaped plate 24 is fixedly connected to the adjacent electric push rod 17.

[0045] Specifically, when performing a vertical drop test on the laptop 18, first hold the laptop 18 by hand and place the laptop 18 between the two clamping plates 22 on the two clamping components. Subsequently, control the second motor 26 to rotate forward. The second motor 26 will drive the threaded rod 25 to rotate. Since 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 will drive the two clamping plates 22 on the two clamping components to approach each other, so that the laptop 18 can be clamped within the two clamping plates 22 on the two clamping components. Subsequently, control the second motor 26 to reverse. When the second motor 26 reverses, it will indirectly drive the two clamping plates 22 on the two clamping components to quickly move away from each other, so that the laptop 18 is no longer clamped. At this time, the laptop 18 will freely fall under its own gravity, so as to perform a vertical drop test on the laptop 18.

[0046] More specifically, when performing a horizontal drop test on the laptop 18, first, the laptop 18 is vertically clamped within the two clamping plates 22 of the two clamping components. Subsequently, the first motor 14 is controlled to rotate. The first motor 14 drives the turntable 13 to rotate by 90 degrees. At the same time, the turntable 13 drives 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 18 to rotate by 90 degrees. When the rotation reaches 90 degrees, at this time, the electric push rod 17 is parallel to the base 1, the threaded rod 25 is perpendicular to the base 1, and at the same time, the laptop 18 is in a horizontal state. Subsequently, the second motor 26 rotates in reverse. During the reverse rotation of the second motor 26, it indirectly drives the two clamping plates 22 on the two clamping components to move away from each other. When the two clamping plates 22 on the two clamping components move away from each other, at this time, the clamping plate 22 no longer clamps the laptop 18. Subsequently, the electric push rod 17 is controlled to quickly contract. During the contraction of the electric push rod 17, it pulls the U-shaped plate 24 to move away from each other. At the same time, the U-shaped plate 24 drives the two clamping components to move away from each other. When the clamping plates 22 on the two clamping components are separated from the laptop 18, at this time, the laptop 18 will fall under its own gravity from the gap between the two clamping components, thereby performing a horizontal drop test on the laptop 18;

[0047] Furthermore, after the laptop 18 is clamped on the two clamping components, at this time, the first motor 14 can be controlled to drive the turntable 13 to rotate within the range of 0 to 90 degrees, thereby driving the laptop 18 to tilt within the range of 0 to 90 degrees. The drop test of the laptop 18 can be performed within this angle range. When testing the laptop 18 at a certain angle, the two clamping plates 22 on the two clamping components are controlled to move away from each other, so as to no longer clamp the laptop 18. Subsequently, the laptop 18 will fall downward at the set angle, thereby enabling the laptop 18 to perform drop tests at different inclined angles;

[0048] Even further, by controlling the rotation of the turntable 13, the turntable 13 drives the two clamping components to rotate, and the clamping components drive the clamped laptop 18 to rotate. After rotation, the laptop 18 can not only perform a vertical drop test but also a horizontal drop test. At the same time, the laptop 18 can be controlled to perform drop tests at different inclined angles within the range of 0 to 90 degrees, thereby simulating the falling states of the laptop 18 under different conditions, and thus improving the diversity of the tests of the laptop 18.

[0049] Embodiment 2: The column 11 is a hydraulic cylinder, and the column 11 rotates on the mounting plate 12 through a rotating shaft;

[0050] Sliding grooves are formed on both sides of each clamping plate 22, and the extension plate 23 slides within the sliding grooves;

[0051] Specifically, during the drop test of the laptop 18, one of the hydraulic cylinders can be controlled to extend. During the extension of the hydraulic cylinder, it will drive one of the mounting plates 12 and the turntable 13 to move upward. At the same time, the rising mounting plate 12 will rotate along the extended hydraulic cylinder. At the same time, during the upward movement of the turntable 13, it will drive the two clamping components to rotate with respect to the other turntable 13 and mounting plate 12, and this mounting plate 12 will rotate along the non-extended 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 clamping plate 22, thus avoiding the situation where the clamping plate 22 and the extension plate 23 are fixed, resulting in the inability of the hydraulic cylinder to drive the mounting plate 12 and the turntable 13 on one side to rotate. When the two clamping components present a certain inclination angle, at this time, vertical drop tests, horizontal drop tests, and drop tests of the laptop 18 at different inclination angles within the range of zero to ninety degrees can be carried out on the basis of the inclination of the two clamping components, so as to further simulate the falling states of the laptop 18 under different conditions and improve the diversity of the drop test of the laptop 18.

[0052] Embodiment Three: At the bottom of each of the two clamping plates 22 on the second clamping component 21, there is provided a support plate 3, and the support plate 3 is fixedly connected to the clamping plate 22 on the second clamping component 21 through uniformly arranged connecting rods.

[0053] In this embodiment, the connecting rod includes a fixed cylinder 31 and a sliding rod 32. The fixed cylinder 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 within the fixed cylinder 31; a threaded hole is provided on the fixed cylinder 31, and a locking bolt 33 is threadedly engaged in the threaded hole, and the fixed cylinder 31 and the sliding rod 32 are locked and fixed through the locking bolt 33.

[0054] In this embodiment, on the opposite side end faces of the two clamping plates 22 on the second clamping component 21, there are respectively provided second convex grooves 34.

[0055] Two second convex blocks 35 are slidably arranged in each of the second convex grooves 34; a stop block 36 is installed on each of the second convex blocks 35, and the distance between the two stop blocks 36 on the same clamping plate 22 is slightly greater than the length of the laptop 18.

[0056] In this embodiment, a countersunk hole is provided on each of the stop blocks 36; an internal hexagonal bolt 37 is provided in each of the countersunk holes. A threaded groove is provided on each of the second convex blocks 35, and the internal hexagonal bolts 37 are threadedly engaged with the threaded grooves.

[0057] Specifically, since the bottom of the two clamping plates 22 on the second clamping assembly 21 is provided with support plates 3, when placing the laptop 18, first place the laptop 18 on one of the support plates 3, and then control the two clamping plates 22 on the two clamping assemblies to approach each other, so as to clamp the laptop 18 within the two clamping assemblies. When the laptop 18 is clamped, at this time, the two support plates 3 do not fit together. During this process, by setting the support plates 3, it is possible to prevent the laptop 18 from being in an inclined state during the placement process; since the opposite sides of the two clamping plates 22 on the second clamping assembly 21 are both provided with stoppers 36, when placing the laptop 18, pass the laptop 18 between the two stoppers 36, so as to limit the position of the laptop 18 and make the laptop 18 in the middle position of the clamping plates 22.

[0058] More specifically, when it is necessary to perform a drop test on laptops 18 of different specifications, at this time, loosen the locking bolt 33 and adjust the distance between the support plate 3 and the clamping plate 22 according to the width of the laptop 18. During the adjustment, the support plate 3 will drive the sliding rod 32 to move up or down in the fixed cylinder 31. When the distance adjustment is completed, then lock the locking bolt 33, so as to press the sliding rod 32 tightly within the fixed cylinder 31; then use a hex wrench to loosen the hexagon socket head bolt 37. After the hexagon socket head bolt 37 is loosened, push the stopper 36 to move according to the length of the laptop 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, then lock the stopper 36 with the hexagon socket head bolt 37.

[0059] Embodiment 4: Limiting grooves 28 are respectively formed at the bottoms of the two clamping plates 22 on the first clamping assembly 2, and the cross-section of the limiting groove 28 is a quarter circle; rubber layers are fixedly connected in both of the limiting grooves 28; rubber layers are also fixedly connected to the upper surfaces of the two support plates 3;

[0060] Specifically, when a drop test needs to be performed on the unfolded laptop 18, first control the two clamping plates 22 on the two clamping components to move away from each other. Then, unfold the laptop 18 and place the two unfolded sides of the laptop 18 on the two support plates 3 respectively. At this time, the distance by which the two clamping plates 22 move away from each other can be controlled according to the angle at which the laptop 18 needs to be unfolded. After the laptop 18 is placed on the two support plates 3, control the two clamping plates 22 on the first clamping component 2 to move closer to each other until they fit. When the two clamping plates 22 on the first clamping component 2 fit, the two limiting grooves 28 form a semi-circular groove. Then, control the electric push rod 17 fixedly connected to the first clamping component 2 to extend. When the electric push rod 17 extends, it will drive the entire first clamping component 2 to move downward, thereby driving the two mutually fitting clamping plates 22 on the first clamping component 2 to move downward. During the downward movement of the two fitting clamping plates 22, they will gradually approach the rotation axis of the laptop 18. After the rotation axis of the laptop 18 extends into the two limiting grooves 28, the unfolded laptop 18 will be restricted on the two limiting components. Subsequently, a vertical drop test, a horizontal drop test, and a drop test at different tilt angles within the range of 0 to 90 degrees can be performed on the basis of the unfolded laptop 18, so as to further simulate the falling states of the laptop 18 under different conditions and improve the diversity of the drop test of the laptop 18;

[0061] More specifically, since rubber layers are fixedly connected to both the limiting grooves 28 and the support plates 3, when the unfolded laptop 18 is limited on the two limiting components, the rubber layers can prevent the limiting grooves 28 and the support plates 3 from directly contacting the laptop 18, thereby causing damage to the laptop 18.
