Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliance testing machinery, and in particular to a computer hot plug and unplug test device. Background Art

[0002] Computer cold start hot plug and unplug test is a test method used to evaluate the performance and reliability of a computer system under different start and plug and unplug conditions. Cold start means the system starts without processes, while hot plug and unplug refers to the operation of inserting and removing devices during the system operation. This test can help discover potential problems in the system's start and device management, ensuring the stability and reliability of the system.

[0003] Existing computer hot plug and unplug test devices generally can only be applicable to the hot plug and unplug test of computers of the same model. For computers of different models, due to more or less deviations in the positions of the plug interfaces, they cannot be applicable. When it is necessary to detect multiple different models of computers, it is also necessary to adjust the installation position of the device or replace the test device, which is time-consuming and laborious to operate and difficult to meet the requirements of on-site operations. Summary of the Invention

[0004] To overcome the technical defect that the existing computer hot plug and unplug test device cannot be applicable to the test of computers of different models, the present invention provides a computer hot plug and unplug test device.

[0005] The computer hot plug and unplug test device provided by the present invention includes:

[0006] A fixed seat, which includes a bottom plate, a placement plate and a vertical plate. The bottom plate and the placement plate are both horizontally arranged and are connected by the vertical plate to form a stepped structure, and the placement plate is located obliquely above the bottom plate;

[0007] An adjustment mechanism, which includes a moving seat, a moving block and a moving frame. The moving seat is installed on the bottom plate and can be driven to approach or move away from the vertical plate in the X direction. The moving block is installed on the moving seat and can be driven to move in the Y direction. The moving frame is installed on the moving block and can be driven to lift in the Z direction;

[0008] A plugging and unplugging mechanism, which includes a plugging and unplugging driving member and a mounting seat. The fixed part of the plugging and unplugging driving member is fixed on the moving frame. The mounting seat is fixed on the output end of the plugging and unplugging driving member. The mounting seat is used to mount a USB flash drive, and the plugging and unplugging driving member is used to drive the mounting seat to extend into the upper part of the placement plate in the X direction to insert the USB flash drive into the computer to be tested;

[0009] The clamping mechanism includes a stop frame and a clamping component. The stop frame is fixed above the end of the storage plate away from the vertical plate. A chute arranged in the X direction is provided at the end of the storage plate close to the vertical plate. The clamping component includes a clamping block slidably connected in the chute and extending above the storage plate. The clamping block is fixedly connected to the moving seat through a cross bar penetrating the vertical plate.

[0010] Optionally, a support rubber strip for supporting the computer to be tested is provided on the storage plate.

[0011] Optionally, the adjustment mechanism further includes an X-direction driving component for driving the moving seat to approach or move away from the vertical plate in the X direction. The X-direction driving component includes a strip-shaped frame fixed on the bottom plate and arranged in the Y direction. Two screws arranged in the X direction are rotatably installed between the strip-shaped frame and the vertical plate. One of the screws is drivingly connected to a first motor and the two screws rotate synchronously through a transmission belt. The moving seat is screwed on the two screws.

[0012] Optionally, the adjustment mechanism further includes a Y-direction driving component for driving the moving block to move in the Y direction. The Y-direction driving component includes a transmission shaft arranged in the X direction and rotatably installed between the strip-shaped frame and the vertical plate. The transmission shaft is drivingly connected to a second motor. One end of the moving seat extends outside the corresponding screw and is fixed with two retaining pieces arranged in the YZ plane. The transmission shaft penetrates through the two retaining pieces. A first transmission wheel is slidably connected to the transmission shaft and is limited between the two retaining pieces. An installation block is fixed on the upper side of the moving seat. A lead screw arranged in the Y direction is rotatably installed on the installation block. The moving block is screwed on the lead screw and is slidably connected to the moving seat. A second transmission wheel is coaxially fixed on the lead screw. The second transmission wheel meshes with the first transmission wheel.

[0013] Optionally, the adjustment mechanism further includes a Z-direction driving component for driving the moving frame to lift in the Z direction. The Z-direction driving component includes at least two guide columns fixed on the moving block and arranged in the Z direction. The moving frame is a U-shaped frame. The web of the U-shaped frame is horizontally arranged and is slidably connected to the moving block through all the guide columns. Inclined sliding holes are provided on both wing plates of the U-shaped frame. The Z-direction driving component further includes a linear driving pair installed on the moving block and arranged horizontally. The output end of the linear driving pair is fixed with a push rod. The push rod passes through the two sliding holes of the U-shaped frame.

[0014] Optionally, the Z-direction driving component further includes two support frames respectively fixed at the two X-direction ends of the moving block. The bottom ends of the guide columns are fixed on the support frames. The linear driving pair is arranged in the X direction. The wing plates of the U-shaped frame are arranged in the XZ plane. When the U-shaped frame is at the lower extreme position, it is lapped on the two support frames.

[0015] Optionally, the linear drive pair is a hydraulic cylinder.

[0016] Optionally, the plug-in drive member is a hydraulic cylinder.

[0017] Optionally, flexible pads are provided on the opposite surfaces of the retaining frame and the clamping block.

[0018] Optionally, the computer hot-swap test device further includes an infrared sensor for detecting the position of the plug interface of the computer under test in the YZ plane.

[0019] The technical solution provided by the present invention has the following advantages compared with the prior art:

[0020] The computer hot-swap test device provided by the present invention, on the one hand, through the cooperation of the moving block and the moving frame, the USB flash drive can be moved to any position in the YZ plane, so that the device can be applied to the detection of computers under test with plug interfaces at different positions in the YZ plane; on the other hand, by driving the clamping block to move along the X direction through the moving seat, the clamping block can be abutted against the surface of the computer under test provided with the plug interface. While cooperating with the retaining frame to clamp and fix the computer under test, since the clamping block is fixedly connected to the moving seat through the cross bar, it can be ensured that the distance between the side wall of the computer under test with the plug interface and the moving seat is a fixed value after being clamped and fixed for computers under test with different X-direction lengths. In this way, the plug-in drive member can complete the detection of computers under test with different X-direction lengths by extending a fixed length, which can effectively avoid excessive insertion force caused by too large a movement stroke of the plug-in drive member after changing the model or the inability to complete the plugging action caused by too small a movement stroke. Through the above two aspects of design, the device can complete the detection of multiple different models of computers without adjusting the installation position or replacing the device, saving time and effort, and can better meet the requirements of on-site operations.

[0035] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the solution of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0036] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.

[0037] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] The following Figures 1 to 10 will be used to detail the specific embodiments of the present invention.

[0039] This embodiment provides a computer hot-swap test device, which includes a fixed seat 1, an adjustment mechanism 2, a plugging mechanism 3, and a clamping mechanism 4.

[0040] Among them, the fixed seat 1 includes a bottom plate 11, a placement plate 12, and a vertical plate 13. The bottom plate 11 and the placement plate 12 are both horizontally arranged and are connected by the vertical plate 13 to form a stepped structure, and the placement plate 12 is located obliquely above the bottom plate 11.

[0041] It is easy to understand that the bottom plate 11 is mainly used to install other adjustment mechanisms 2; the placement plate 12 is mainly used to place the computer to be tested; the vertical plate 13 is mainly used to form a height difference between the bottom plate 11 and the placement plate 12 to make up for the deficiency that the plugging position is too high due to the height of the adjustment mechanism 2 itself, so that the device can be applicable to the detection of computers with a lower plug-in interface position such as laptops.

[0042] Furthermore, the placement plate 12 is provided with a support rubber strip 122 for supporting the computer to be tested. The support rubber strip 122 is in soft contact with the bottom of the computer to be tested, which can avoid the collision damage of the computer to be tested.

[0043] It should be noted that the storage plate 12 is also provided with a slide groove 121, which is used to cooperate with the clamping mechanism 4. For better understanding, the specific structure and function of the slide groove 121 will be described in detail in the part about the clamping mechanism 4 later.

[0044] Wherein, the adjustment mechanism 2 includes a moving seat 21, a moving block 22 and a moving frame 23. The moving seat 21 is mounted on the bottom plate 11 and can be driven to approach or move away from the vertical plate 13 along the X direction. The moving block 22 is mounted on the moving seat 21 and can be driven to move along the Y direction. The moving frame 23 is mounted on the moving block 22 and can be driven to rise and fall along the Z direction. During operation, the moving seat 21 moves along the X direction to drive the moving block 22 and the moving frame 23 to move synchronously in the X direction. The moving block 22 moves along the Y direction to drive the moving frame 23 to move synchronously in the Y direction. The moving frame 23 itself can rise and fall along the Z direction, so the moving frame 23 and the components mounted on the moving frame 23 can achieve translation in the three orthogonal axis directions of X, Y and Z in space.

[0045] Specifically, the adjustment mechanism 2 of this embodiment also includes an X-direction driving assembly 24 for driving the moving seat 21 to approach or move away from the vertical plate 13 along the X-direction. The X-direction driving assembly 24 includes a strip frame 241 fixed on the bottom plate 11 and arranged along the Y-direction. Two screws 242 arranged along the X-direction are rotatably installed between the strip frame 241 and the vertical plate 13. One of the screws 242 is transmission-connected to the first motor 243 and the two screws 242 rotate synchronously through the transmission belt 244. The moving seat 21 is screwed on the two screws 242. When working, the output shaft of the first motor 243 drives one of the screws 242 to rotate, and the two screws 242 rotate synchronously through the transmission belt 244, thereby driving the moving seat 21 screwed on the screw 242 to move along the X-direction.

[0046] More specifically, in this embodiment, the housing of the first motor 243 is fixed to the side of the strip frame 241 away from the vertical plate 13, and the ends of the two screw rods 242 close to the strip frame 241 are fixedly mounted with pulleys 245, and the transmission belt 244 is wound around the two pulleys 245.

[0047] Specifically, the adjustment mechanism 2 of this embodiment further includes a Y-direction driving component 25 for driving the moving block 22 to move in the Y direction. The Y-direction driving component 25 includes a transmission shaft 251 rotatably installed between the strip-shaped frame 241 and the vertical plate 13 and arranged in the X direction. The transmission shaft 251 is drivingly connected to a second motor 252. One end of the moving seat 21 extends outside the corresponding screw 242 and is fixed with two retaining pieces 253 arranged in the YZ plane. The transmission shaft 251 penetrates through the two retaining pieces 253. A first transmission wheel 254 is slidably connected to the transmission shaft 251 and the first transmission wheel 254 is limited between the two retaining pieces 253. An installation block 255 is fixed on the upper side of the moving seat 21. A lead screw 256 arranged in the Y direction is rotatably installed on the installation block 255. The moving block 22 is screwed on the lead screw 256 and slidably connected to the moving seat 21. A second transmission wheel 257 is coaxially fixed on the lead screw 256. The second transmission wheel 257 meshes with the first transmission wheel 254. During operation, the output shaft of the second motor 252 drives the transmission shaft 251 to rotate. The transmission shaft 251 drives the first transmission wheel 254 to rotate. The first transmission wheel 254 drives the second transmission wheel 257 to rotate. The second transmission wheel 257 drives the lead screw 256 to rotate, thereby driving the moving block 22 screwed on the lead screw 256 to move in the Y direction. The Y-direction driving component 25 of this embodiment arranges the power element on the bottom plate 11. Compared with the solution of arranging the power element on the moving seat 21, it can effectively reduce the Z-direction height of the overall device, which is more conducive to the detection of computers with lower plug-in interface positions such as laptops.

[0048] More specifically, the first transmission wheel 254 and the second transmission wheel 257 can adopt an orthogonal helical gear pair or a bevel gear pair, or a worm and worm gear pair. However, when adopting a worm and worm gear pair, the first transmission wheel 254 needs to be a worm.

[0049] More specifically, a through groove 259 arranged in the X direction is formed on the outer side wall of the transmission shaft 251. A convex strip 258 adapted to the through groove 259 is formed on the inner wall of the first transmission wheel 254. The convex strip 258 is placed in the through groove 259 to realize the sliding connection between the first transmission wheel 254 and the transmission shaft 251.

[0050] Specifically, the adjustment mechanism 2 of this embodiment further includes a Z-direction drive assembly 26 for driving the moving frame 23 to lift in the Z direction. The Z-direction drive assembly 26 includes at least two guide columns 261 that are fixed on the moving block 22 and arranged in the Z direction. The moving frame 23 is a U-shaped frame. The web of the U-shaped frame is horizontally arranged and is slidably connected to the moving block 22 through all the guide columns 261. Oblique sliding holes 262 are formed on the two wing plates of the U-shaped frame. The Z-direction drive assembly 26 further includes a linear drive pair 263 that is installed on the moving block 22 and arranged horizontally. A push rod 264 is fixed at the output end of the linear drive pair 263. The push rod 264 passes through the two sliding holes 262 of the U-shaped frame. During operation, the linear drive pair 263 drives the push rod 264 to move horizontally. Since the sliding holes 262 of the U-shaped frame are obliquely arranged, the push rod 264 will drive the U-shaped frame to lift in the Z direction. The Z-direction drive assembly 26 of this embodiment horizontally arranges the linear drive pair 263 on the moving block 22. Compared with the solution of vertically arranging the linear drive pair 263 on the moving block 22, it can effectively reduce the overall Z-direction height of the device, which is more conducive to the detection of computers such as laptop computers with lower plug-in interface positions.

[0051] More specifically, the Z-direction drive assembly 26 of this embodiment further includes two support frames 265 respectively fixed at the two X-direction ends of the moving block 22. The bottom ends of the guide columns 261 are fixed on the support frames 265. The linear drive pair 263 is arranged in the X direction. The wing plates of the U-shaped frame are arranged in the XZ plane. When the U-shaped frame is at the lower limit position, it overlaps on the two support frames 265. By using the support frames 265 to support the U-shaped frame at the lower limit position, rather than relying only on the cooperation between the push rod 264 and the sliding groove 121 for support, it is more conducive to ensuring the structural stability.

[0052] In detail, there are four guide columns 261 in this embodiment and they are distributed in a rectangle. Each support frame 265 is connected to two guide columns 261. The two guide columns 261 located on the same support frame 265 are distributed in the Y direction. The two guide columns 261 distributed in the X direction are connected by a connecting rod 266. The four guide columns 261 form an integral body through the connecting rod 266 and the support frames 265, which can improve the structural stability of the guide columns 261. At the same time, the connecting rod 266 also serves as a limit frame to determine the upper limit position of the U-shaped frame.

[0053] In detail, the linear drive pair 263 of this embodiment is a hydraulic cylinder.

[0054] Among them, the plugging mechanism 3 includes a plugging driving member 31 and a mounting seat 32. The fixing part of the plugging driving member 31 is fixed on the moving frame 23, and the mounting seat 32 is fixed on the output end of the plugging driving member 31. The mounting seat 32 is used for mounting the USB flash drive, and the plugging driving member 31 is used to drive the mounting seat 32 to extend above the storage board 12 along the X direction to insert the USB flash drive into the computer to be tested. During operation, the plugging driving member 31 drives the mounting seat 32 and the USB flash drive to move along the X direction.

[0055] It is easy to understand that the stroke of the plugging driving member 31 determines whether the plugging action can be successfully completed: if the stroke of the plugging driving member 31 is too large, that is, the stroke of the plugging driving member 31 is greater than the distance between the USB flash drive and the side surface where the plug interface of the computer to be tested is located, it is easy to cause too large a plugging force of the USB flash drive, resulting in damage to the plug interface of the computer to be tested; if the stroke of the plugging driving member 31 is too small, that is, the stroke of the plugging driving member 31 is less than the distance between the USB flash drive and the side wall where the plug interface of the computer to be tested is located, it is easy to cause the USB flash drive not to be inserted into the plug interface. In this device, the clamping block 421 of the clamping mechanism 4 is linked with the moving seat 21, and the position of the moving seat 21 is physically limited by the clamping block 421, so that after the computer to be tested is clamped and fixed, the distance between the side wall where the plug interface of the computer to be tested is located and the moving seat 21 is a fixed value, so that for different models of computers, the stroke required for the USB flash drive plugging action is the same, and thus it is possible to avoid the stroke of the plugging driving member 31 being too large or too small.

[0056] Specifically, the plugging driving member 31 in this embodiment is a hydraulic cylinder.

[0057] Among them, the clamping mechanism 4 includes a blocking frame 41 and a clamping component 42. The blocking frame 41 is fixed above the end of the storage board 12 far from the vertical board 13. A chute 121 arranged along the X direction is opened at the end of the storage board 12 close to the vertical board 13. The clamping component 42 includes a clamping block 421 slidably connected in the chute 121 and extending above the storage board 12. The clamping block 421 is fixedly connected to the moving seat 21 through a cross bar 422 penetrating the vertical board 13.

[0058] Specifically, there are two chutes 121 in this embodiment and they are distributed along the Y direction. There are also two clamping blocks 421 corresponding to the chutes 121. The two clamping blocks 421 cooperate with the blocking frame 41 to clamp and fix the computer to be tested, and the clamping is more reliable.

[0059] Specifically, a mounting plate 423 is fixed at one end of the cross bar 422 in this embodiment. The two clamping blocks 421 are fixed on the mounting plate 423. A fixing frame 424 is fixed at the other end of the cross bar 422, and the fixing frame 424 is fixedly connected to the moving seat 21.

[0060] Furthermore, flexible pads are provided on the opposite surfaces of the blocking frame 41 and the clamping block 421. The flexible pads are in soft contact with the side wall of the computer to be tested, and can avoid knocking and damaging the computer to be tested.

[0061] In addition, the computer hot-swap test device of this embodiment further includes an infrared sensor 5, which is used to detect the position of the plug interface of the computer to be tested in the YZ plane. During operation, the infrared sensor 5 detects the precise position of the plug interface, and then controls the movement of the moving block 22 and the moving frame 23 so that the USB flash drive can be accurately aligned with the plug interface with a high precision.

[0062] Specifically, the infrared sensor 5 of this embodiment is fixed at one end of the moving block 22 close to the vertical plate 13 to better obtain the position of the plug interface.

[0063] The working process of the computer hot-swap test device of this embodiment is as follows:

[0064] S1. Place the computer to be tested on the support rubber strip 122 of the placement board 12;

[0065] S2. Install the USB flash drive on the mounting seat 32;

[0066] S3. The first motor 243 is started to drive the moving seat 21 to approach the vertical plate 13, and the clamping block 421 moves synchronously with the moving seat 21 until the clamping block 421 abuts against the side wall of the computer to be tested;

[0067] S4. The infrared sensor 5 detects the position of the plug interface of the computer to be tested in the YZ plane, and then controls the second motor 252 and the linear drive pair 263 to start, driving the moving frame 23 to move in the Y direction and the Z direction until the USB flash drive is aligned with the plug interface of the computer to be tested;

[0068] S5. The plugging driving member 31 is started to drive the USB flash drive to approach the plug interface of the computer to be tested until the USB flash drive is inserted into the plug interface;

[0069] S6. Detect the computer to be tested through a supporting detection device;

[0070] S7. After the detection is completed, all components are reset to wait for the next computer to be tested.

[0071] The above are only specific implementation manners of the present invention, enabling those skilled in the art to understand or implement the present invention. Although the above embodiments have been described in detail, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the above embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the above embodiments, and they should all be covered by the protection scope of the claims.
