Description

Technical Field

[0001] This invention relates to the field of computer system service debugging and switching technology, specifically to a computer system service debugging and switching device that supports multi-interface expansion. Background Technology

[0002] In the process of computer hardware research and development, production testing, system integration, and subsequent operation and maintenance services, it is often necessary to perform low-level debugging, diagnosis, and firmware updates on computer systems (such as servers, industrial control computers, network devices, etc.). Such work usually involves multiple physical interfaces, such as UART serial ports for system consoles, JTAG interfaces for processor kernel debugging, USB interfaces for accessing peripherals, and bus interfaces such as I2C and SPI for configuration management.

[0003] Currently, technicians typically use the following method when performing multi-interface debugging: the debugging host (such as an engineer's laptop) is connected to the target system under test via a multi-functional protocol converter or docking station (i.e., an "adapter"). This adapter integrates multiple types of physical ports. However, existing debugging adapters of this type have the following significant drawbacks in practical applications: Existing equipment typically comes with multiple external cables of fixed length. During use, these cables easily become tangled and dragged, resulting in a messy work surface. When not in use, cable management is also extremely inconvenient, often requiring manual winding and tidying, which is time-consuming and labor-intensive. Especially in scenarios requiring rapid switching between multiple test points or simultaneous use of multiple cables, manual cable management and plugging / unplugging are extremely cumbersome, severely impacting the efficiency of debugging work. Furthermore, cables scattered on the floor pose safety hazards such as tripping over personnel and accidental pulling that could damage interfaces.

[0004] Most existing products have fixed interface types and numbers. When faced with a debugging task that requires only a few specific interfaces, the extra interfaces and cables become a burden; and when it is necessary to connect to a special interface that is not provided by the device itself, it is necessary to use additional, separate converters, which disrupts the integrity of the debugging toolchain and increases connection complexity and points of failure.

[0005] As a type of precision electronic equipment, debugging adapters are prone to accumulating dust, metal shavings, and other foreign matter on their exposed electrical interfaces (ports) when not in use, or being damaged in humid or splashy environments. Most existing products lack effective physical protection measures, and long-term exposure of ports may lead to poor contact, short circuits, or even permanent damage, greatly shortening the equipment's lifespan and potentially affecting important debugging tasks at critical moments due to interface failure. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a computer system service debugging and switching device that supports multiple interface expansion, thus solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a computer system service debugging adapter supporting multi-interface expansion, comprising an expansion adapter, wherein several end seats are mounted on the side of the expansion adapter, several detachable storage mechanisms are placed on the outside of the expansion adapter, the storage mechanisms are connected to the expansion adapter via the end seats, a fixing mechanism is mounted on the top of the expansion adapter, and the storage mechanisms are mounted on the expansion adapter via the fixing mechanism, an active mechanism for driving the storage mechanisms is fixedly mounted on the bottom of the expansion adapter, and a protective mechanism is mounted on the outside of the expansion adapter above the end seats; The storage mechanism includes a storage box, inside which a take-up roller is rotatably connected via bearings. A drive frame is fixedly installed on the outside of the storage box. Two traction rollers are rotatably connected inside the drive frame. A wire is wound around the outside of the take-up roller. One end of the wire passes between the two traction rollers and extends to the outside of the drive frame, where a movable plug is installed.

[0008] Preferably, a rotating shaft is fixedly installed at one end of the take-up roller, and one end of the rotating shaft extends into the drive frame. A first sprocket, which is connected to the outer side of one of the traction rollers and the outer side of the rotating shaft, is fixedly sleeved on the outside of the roller and is driven by a chain belt. An insertion box is fixedly installed at the bottom of the drive frame. A rotating rod is rotatably connected to the inside of the insertion box through a bearing. A second sprocket, which is connected to the outer side of the rotating rod and the rotating shaft, is fixedly sleeved on the outside of the insertion box through a bearing. A rotating column is rotatably connected to the bottom of the insertion box through a bearing. A meshing bevel gear is fixedly sleeved on the outer side of the rotating column and the rotating rod. A first drive gear is fixedly sleeved on the outer side of the top of the rotating column. A meshing transmission gear is fixedly sleeved on the outer side of both traction rollers.

[0009] Those skilled in the art will understand that by using a rotary joint in conjunction with a fixed plug, the circuit remains continuous during the winding and rotation of the wire, preventing twisting and breakage. At the same time, it enables rapid electrical connection between the storage mechanism and the expansion adapter, improving connection stability and wiring efficiency.

[0010] Preferably, a rotary joint is installed on the side of the storage box, a fixed plug is installed at one end of the rotary joint, one end of the wire passes through the inside of the take-up roller and is connected to the other end of the rotary joint, and one end of the fixed plug is inserted into the end seat.

[0011] Those skilled in the art will know that an electric drive structure consisting of a motor, a threaded rod, a pusher, and a second rack can automatically output power to retract and extend the wire, replacing manual pulling, avoiding damage to the joint and the wire, and improving the degree of automation and the service life of the device.

[0012] Preferably, the active mechanism includes an active housing, which is fixedly installed at the bottom of the extension adapter. A threaded rod is rotatably mounted inside the active housing via a bearing. A push block is mounted on the outer side of the threaded rod, and the interior of the push block cooperates with the outer side of the threaded rod. A second rack is fixedly mounted on the side of the push block. A motor is fixedly mounted on the side of the active housing, and the output end of the motor is connected to one end of the threaded rod via a coupling.

[0013] Those skilled in the art will know that by monitoring the displacement of the push block in real time through the pull rope sensor, the extension length of the wire can be precisely controlled. In conjunction with the reliable meshing and transmission between the second rack and the storage mechanism, the wire length can be adjusted as needed and the positioning can be accurate, meeting the requirements of different debugging distances.

[0014] Preferably, the fixing mechanism includes a positioning rail, a drive rail fixedly mounted at one end of the positioning rail, the bottom of the drive rail fixedly connected to the top of the expansion adapter, an insertion strip fixedly mounted at one end of the drive frame, one end of the insertion strip inserted into the positioning rail, a fixing cylinder fixedly mounted at the top of the positioning rail, a screw threaded into a threaded hole at the top of the fixing cylinder, a push post fixedly mounted at the bottom of the screw, a positioning hole at the top of the insertion strip, and the bottom end of the push post inserted into the positioning hole.

[0015] Those skilled in the art will know that by using positioning rails, insert bars, screws, push pins and positioning holes, the storage mechanism can be inserted, positioned and tightened, making disassembly and assembly simple and the connection firm, preventing loosening and falling off during debugging, and ensuring the stability of electrical connection and debugging work.

[0016] Preferably, the protection mechanism includes a mounting block and a drive box, both of which are mounted on the outside of the extension adapter. A hinge shaft is rotatably connected between the mounting block and the drive box via a bearing, and a sealing plug is fixedly mounted on the outside of the hinge shaft.

[0017] Those skilled in the art will know that the interface protection structure, consisting of the mounting block, hinge shaft, and sealing plug, automatically seals the end-seat interface when the storage mechanism is not installed, achieving dustproof, moisture-proof, and oxidation-proof protection, adapting to complex industrial and computer room environments, and extending the lifespan of the expansion adapter interface.

[0018] Preferably, the main unit is mounted on top of the extension adapter and above the fixing mechanism.

[0019] Those skilled in the art will recognize that by setting a host on the top of the expansion adapter, control, drive, interface expansion, and debugging can be integrated into one, resulting in a compact structure, reasonable layout, easy portability and field deployment, and meeting the one-stop debugging needs of computer system services.

[0020] This invention provides a computer system service debugging and switching device that supports multiple interface expansion, and has the following beneficial effects: 1. This computer system service debugging adapter, supporting multi-interface expansion, automatically controls the take-up roller and traction roller within the storage mechanism via a motor drive in the active mechanism, achieving automatic cable release and retraction. This avoids the tedious manual cable management, significantly improving work efficiency, especially when frequently changing test points or using multiple cables. Several end caps on the side of the device support the connection of multiple independent storage mechanisms. This means that, according to actual debugging needs, specific interface types of connecting cables can be flexibly added or removed by replacing storage mechanisms with different movable plugs, achieving modular expansion of interfaces, which is more flexible than fixed-interface adapters.

[0021] 2. This computer system service debugging adapter, supporting multi-interface expansion, utilizes a protective mechanism. When the storage mechanism is removed, the sealing plug automatically rotates and seals the exposed end-port interface under the drive of springs and gear chains such as worm gears and worm shafts. This effectively prevents dust, foreign objects, or liquids from entering the idle ports, extending the service life and reliability of the core adapter. The entire device's mechanical design features a linkage mechanism. When the storage mechanism is inserted, its movement drives the sealing plug of the protective mechanism to open; during disassembly, the linkage process drives the sealing plug to close. This design reduces the steps of individually operating each function, lowers the possibility of misoperation, and ensures the correct sequence and integrity of operations.

[0028] The fixing mechanism 6 includes a positioning rail 602, a drive rail 601 fixedly mounted at one end of the positioning rail 602, the bottom of the drive rail 601 fixedly connected to the top of the expansion adapter 1, an insertion bar 604 fixedly mounted at one end of the drive frame 302, one end of the insertion bar 604 inserted into the positioning rail 602, a fixing cylinder 605 fixedly mounted at the top of the positioning rail 602, a screw 606 threadedly connected to the threaded hole at the top of the fixing cylinder 605, a push post 607 fixedly mounted at the bottom of the screw 606, a positioning hole 603 opened at the top of the insertion bar 604, and the bottom end of the push post 607 inserted into the positioning hole 603.

[0029] The protection mechanism 5 includes a mounting block 501 and a drive box 504. Both the mounting block 501 and the drive box 504 are mounted on the outside of the extension adapter 1. A hinge shaft 502 is rotatably connected between the mounting block 501 and the drive box 504 via a bearing. A sealing plug 503 is fixedly mounted on the outside of the hinge shaft 502.

[0030] The main unit 2 is mounted on the top of the extension adapter 1 and above the fixing mechanism 6.

[0031] In the first embodiment, when installing and disassembling the storage mechanism 3, the hinge shaft 502 is manually rotated so that the hinge shaft 502 drives the sealing plug 503 to rotate out from the front end of the end seat 4, or the hinge shaft 502 is manually rotated so that one end of the hinge shaft 502 drives the sealing plug 503 to be inserted into the front end of the end seat 4.

[0032] Example 2 Please see Figures 1 to 9 The present invention provides a technical solution: a spring 609 is fixedly installed on one side inside the drive rail 601, a top post 610 is fixedly installed on one end of the spring 609, one end of the top post 610 extends into the positioning rail 602 and is fixedly installed with a push plate 608, a connecting strip 612 is fixedly installed on one side of the push plate 608, one end of the connecting strip 612 extends into the drive rail 601 and is fixedly installed with a first rack 611, a connecting post 613 is rotatably connected to the inner cavity of the drive rail 601 through a bearing, and a second drive gear 614 that cooperates with the first rack 611 is fixedly sleeved on the outer side of the connecting post 613.

[0033] The bottom end of the connecting column 613 extends into the drive box 504, one end of the hinge shaft 502 extends into the drive box 504 and is fixedly fitted with a worm gear 506, a worm 505 is rotatably connected to the drive box 504 through a bearing, the worm 505 is connected to the worm gear 506 through a transmission, and a third sprocket 507 connected by a chain belt is fixedly fitted on the outer side of both the worm 505 and the connecting column 613.

[0034] The combined working principle of Example 2 and Example 1: If additional wiring ports are needed, remove the storage mechanism 3 and push it towards the end seat 4 on the outside of the expansion adapter 1, so that one end of the insertion bar 604 is inserted into the positioning rail 602. At this time, the insertion bar 604 pushes the push plate 608 to overcome the supporting force of the spring 609, causing the push plate 608 to move inward. This push plate 608 pushes the connecting bar 612 and the first rack 611 to move, causing the first rack 611 to drive the second drive gear 614 to drive the connecting column 613 and the third sprocket 507 to rotate, thus causing the third... The sprocket 507 drives the worm gear 506 via the worm 505, which in turn drives the hinge shaft 502 to rotate. This causes the hinge shaft 502 to drive the sealing plug 503 to rotate, allowing the sealing plug 503 to rotate out from the front end of the end seat 4 and rotate upwards. During this process, the distance between the fixed plug 316 and the end seat 4 is sufficient to allow the sealing plug 503 to rotate. Then, the storage mechanism 3 continues to move until one end of the fixed plug 316 is inserted into the front end of the end seat 4. At this point, the push plate 608 pushes the connecting strip 612 and the first rack 611 to move to the desired position. Figure 7 The location shown; Then, tighten screw 606 so that screw 606 pushes the bottom end of push post 607 into the positioning hole 603 to fix the position of insert strip 604 and storage mechanism 3. In use, the output end of the motor 705 drives the threaded rod 702 to rotate, which in turn drives the push block 703 and the second rack 704 to move. One end of the second rack 704 is inserted into the insertion box 303, which in turn drives the bevel gear 318 through the first drive gear 312 to rotate the rotating rod 309. The rotating rod 309 then drives the second sprocket 310 and the rotating shaft 307 to rotate, which in turn drives the take-up roller 317 to release the wire 313. The first sprocket 308 drives one traction roller 305 to rotate, which in turn drives another traction roller 305 to rotate through the transmission gear 306. The two traction rollers 305 together drive the wire 313 to move out of the storage box 301. The movable plug 314 is connected to the wire 313 and the rotary joint 315, and the fixed plug 316 is connected to the end plate 4 via the expansion adapter 1. The debugging work is carried out by connecting the other end plate 4, the fixed plug 316 and the rotary joint 315, and the wire 313 to the movable plug 314 and the computer. When not in use, the output end of the motor 705 drives the threaded rod 702 to reset and rotate, causing the threaded rod 702 to drive the push block 703 and the second rack 704 to reset and move. This causes one end of the second rack 704 to move out of the insertion box 303 through the insertion port 304, thereby driving the bevel gear 318 through the first drive gear 312 to drive the rotating rod 309 to reset and rotate. This causes the rotating rod 309 to drive the second sprocket 310 and the rotating shaft 307 to reset and rotate. This causes the rotating shaft 307 to drive the winding roller 317 to wind up the wire 313. In addition, the first sprocket 308 drives a traction roller 305 to reset and rotate. This traction roller 305 drives another traction roller 305 to reset and rotate through the transmission gear 306, so that the two traction rollers 305 together drive the wire 313 to be conveyed into the storage box 301. When removal is required, screw 606 is turned, causing screw 606 to move push post 607 out of positioning hole 603. Then, the storage mechanism 3 is pulled to move, causing insert strip 604 to move outward from positioning rail 602. When the distance between fixed plug 316 and end seat 4 is fully sufficient to meet the rotation requirements of sealing plug 503, the first rack 611 contacts the second drive gear 614, causing the first rack 611 to drive the second drive gear 614 to drive connecting post 613 and third sprocket 507 to reset and rotate. The third sprocket 507 drives worm wheel 506 through worm 505 to drive hinge shaft 502 to reset and rotate. The hinge shaft 502 drives sealing plug 503 to reset and rotate, causing one end of sealing plug 503 to rotate to the front end of end seat 4. Then, insert strip 604 is pulled out from positioning rail 602, thus completing disassembly.
