Description

Technical Field

[0001] This invention relates to educational equipment, and more specifically to the field of teaching support frames, particularly to a support frame for computer hardware teaching demonstrations. Background Technology

[0002] In computer hardware-related teaching and training activities, e-learning (such as PPT presentations, 3D animations, and video demonstrations) has become the mainstream model. While this method has the advantages of standardized content and replayability, it has the drawback of students not being able to touch, observe, and perceive real hardware entities. To enable students to gain intuitive understanding, teachers usually need to demonstrate various physical hardware components such as motherboards, CPUs, memory, hard drives, and expansion cards. Currently, common teaching methods rely on ordinary storage boxes to store hardware, which is then temporarily taken out and laid flat on the podium during class.

[0003] However, simply displaying hardware components on a regular desktop or display stand can easily lead to cluttered and obstructed computer hardware, completely blocking students' view from behind, requiring teachers to constantly pick up the hardware, frequently interrupting the teaching process, and resulting in low efficiency. Summary of the Invention

[0004] To address the limitations of current demonstration methods in terms of limited display space and single perspective, this application provides a support frame for computer hardware teaching demonstrations.

[0005] The support frame for computer hardware teaching demonstration provided in this application adopts the following technical solution:

[0006] A support frame for computer hardware teaching demonstration includes a support base and a support cylinder disposed within the support base. A carrier box is slidably disposed on the support cylinder. The carrier box has an upper chamber and a lower chamber. Several radially sliding placement boxes are arranged in an array along the circumferential direction in the upper chamber for accommodating non-plate-shaped computer hardware. Several placement plates for accommodating plate-shaped computer hardware are arranged in an array along the circumferential direction in the lower chamber.

[0007] A control component is installed inside the support cylinder. The control component is used to drive the carrier box to rise along the support cylinder and, after rising to a predetermined height, drive it to rotate around the axis of the support cylinder. A handle is fixedly installed on the support cylinder. The handle and an unfolding component one installed in the upper chamber are used to drive all the placement boxes to move outward synchronously radially a first preset distance when the carrier box rotates. An unfolding component two is installed in the lower chamber to drive all the placement plates to move outward synchronously radially a second preset distance when the carrier box rotates. During the movement, the placement plates are driven to change from a horizontal state to an inclined state, thereby forming a stepped display layout with the unfolded placement boxes in the upper chamber.

[0008] By adopting the above technical solution, the support base and support cylinder constitute the main skeleton. The carrier box and its internal upper and lower chambers realize the layered and classified storage of computer hardware. The upper radially sliding placement box is used to place three-dimensional hardware, and the lower placement plate is used to place plate-shaped hardware. The control component drives the carrier box to complete the core actions of rising and rotating, so that the two can use the rotational power of the carrier box to drive all placement boxes and placement plates to expand radially synchronously to form a display layout. During the movement, the second expansion component changes the placement plate from a horizontal state when stored to an inclined state when displayed, thus forming a stepped display layout without visual obstruction together with the upper placement box, maximizing space utilization. The inclined state of the placement plate allows students in the back row to easily see the entire board and layout, solving the problem of visual obstruction when statically placed flat, and improving the efficiency of teachers' teaching.

[0009] Preferably, the control component includes a drive member fixedly disposed within a support base, a bevel gear set disposed on the drive member, a threaded rod disposed at the end of the bevel gear set away from the drive member and located within a support cylinder, the threaded rod being rotatably disposed through the support base, a control groove being formed on the support cylinder, a movable block being threadedly disposed on the threaded rod and sliding within the control groove, the movable block being fixedly connected to a bearing box, and two bellows being sleeved on the support cylinder, one of the bellows having its two ends fixed to the support cylinder and the bearing box respectively, and the other bellows having its two ends fixed to the bearing box and the support base respectively.

[0010] By adopting the above technical solution, the driving component provides power, changes the torque direction through the bevel gear set and drives the threaded rod to rotate. The moving block meshing with the threaded rod, under the control groove of the support cylinder, converts the rotational motion into linear motion, thereby driving the lifting and lowering of the load-bearing box. The corrugated pipe is used to shield the internal structure and prevent dust, while its extensibility does not interfere with the movement.

[0011] Preferably, the unfolding component includes a first frame that slides within the upper cavity. The first frame has a plurality of first parallel grooves arranged in an array along the circumferential direction. The carrier box has a first limiting groove arranged in an array along the circumferential direction. A first cylinder is slidably disposed in both the first limiting groove and the first parallel groove. The carrier box has a first arc groove. A first limiting rod that is fixedly connected to the first frame is slidably disposed in the first arc groove. The handle has a first circular hole that matches the size of the first limiting rod.

[0012] By adopting the above technical solution, when the carrier box rotates, the first limiting rod fixed to the handle restricts the rotation of the first frame through the first circular hole, so that the first parallel groove on the first frame and the first limiting groove on the carrier box generate relative displacement, forcing the first cylinder sliding between the two to drive the placement box to move radially in a straight line, thereby achieving synchronous unfolding.

[0013] Preferably, the second unfolding component includes a second frame that slides within the lower chamber. The second frame has a plurality of second parallel grooves arranged in an array along the circumferential direction. The carrier box has a second limiting groove arranged in an array along the circumferential direction. A second cylinder is slidably disposed in both the second limiting groove and the second parallel groove. The carrier box has a second arc groove. A second limiting rod that is fixedly connected to the second frame is slidably disposed in the second arc groove. The handle has a second circular hole that matches the size of the second limiting rod. The second cylinder achieves the tilting of the placement plate through an angle adjustment structure.

[0014] By adopting the above technical solution, the second limiting rod fixed to the handle restricts the rotation of the second frame through the second circular hole, and the relative movement between the second parallel groove and the second limiting groove drives the second cylinder to move radially, thereby ultimately realizing the unfolding and tilting of the placement plate through the angle adjustment structure.

[0015] Preferably, the angle adjustment structure includes an inclined groove formed in the second frame, a sliding rod slidably disposed in the inclined groove and rotatably disposed in the placement plate, a sliding plate hinged to the placement plate, the second cylinder being fixedly connected to the sliding plate, and the sliding plate being slidably disposed with the second frame.

[0016] By adopting the above technical solution, in the angle adjustment structure, when the slide plate fixed to the second cylinder drives the placement plate to move radially, the slide rod fixed on the placement plate is forced to slide in the inclined groove of the second frame. This motion trajectory converts the radial translation of the placement plate into rotation about its hinge point with the slide plate, thereby realizing automatic tilting.

[0017] Preferably, an LED light and a switch for controlling the LED light are fixedly installed inside the skateboard. The switch is fitted with a spring that is fixedly connected to the skateboard. A pressure block that is fixedly installed on the spring and whose movement is controlled by the state of the skateboard is fixedly mounted on the spring.

[0018] By adopting the above technical solution, when the placement plate is in a horizontal storage state, the pressure block is pressed down and the spring is compressed to trigger the switch to turn off the LED light; when the placement plate is tilted and unfolded, the pressure block is reset and the switch is released under the action of the spring, automatically turning on the LED light, thus realizing intelligent linkage between lighting and display status.

[0019] Preferably, a plurality of magnets are fixedly arranged inside the placement box, and magnets two that attract each other are arranged on the magnets one.

[0020] By adopting the above technical solution, the magnet one fixed to the placement box and the movable magnet two attract each other to form an adjustable magnetic clamping area, which is used to flexibly restrict irregularly shaped three-dimensional hardware such as mice and fans, and prevent them from shaking or tipping over when moved or displayed.

[0021] Preferably, a storage battery is provided inside the support base, a display screen for demonstration is fixedly installed on the carrier box, and an installation slot for installing computer hardware is provided on the carrier box.

[0022] By adopting the above technical solution, the battery in the support base provides built-in power for the motor, LED lights and display screen of the entire device, enhancing portability; the display screen on the carrier box can be used to play teaching materials, and the mounting slot provides a point for temporarily fixing specific hardware to be explained.

[0023] Preferably, both the placement box and the placement plate are made of transparent acrylic sheet, and both the surface of the placement box and the placement plate are covered with an anti-static film.

[0024] By adopting the above technical solution, the use of transparent acrylic sheets to make the placement box and placement board ensures the visibility of the hardware; the anti-static film on the surface can effectively prevent the accumulation of static electricity and avoid static damage to the delicate computer hardware during the handling process.

[0025] Preferably, the first frame is slidably connected to the placement box, and the second frame is slidably connected to the placement plate.

[0026] By adopting the above technical solution, the sliding connection between the first frame and the placement box, and between the second frame and the placement plate, ensures that the two can move smoothly relative to each other in the radial direction during the unfolding and storage process. This is the key mechanical constraint for achieving synchronous and stable unfolding.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The threaded rod and bevel gear set driven by the drive component control the lifting and rotation of the carrier box within the support cylinder. When not in demonstration mode, the entire carrier box is located within the support base. The support frame is a compact box with wheels, which greatly saves space. The support cylinder and handle are designed to form a suitcase-like shape, making it easy to move and store. During demonstration, the carrier box rises and unfolds the placement box and placement plate, instantly transforming the storage volume into a multi-layered, radial, three-dimensional display space, maximizing space utilization and improving the display effect.

[0029] 2. By independently controlling the first and second unfolding components, the upper layer (3D hardware) and the lower layer (plate-shaped hardware) can be unfolded in layers and at different distances. The upper layer unfolds at a shorter distance, while the lower layer unfolds at a longer distance, forming a clear visual ladder. This ensures that the hardware in the placement box and the placement plate are presented to the trainees simultaneously and without obstruction. The classification is clear, and the retrieval is intuitive. The plate-shaped and 3D hardware are stored separately, avoiding mutual scratching and confusion in retrieval.

[0030] 3. By using a hinged structure between the sliding plate and the placement board in the lower layer, combined with the inclined groove design on the second frame, the placement board can not only expand radially with the moving board during the unfolding process, but its free end can also slide along the inclined groove and automatically rise to form a stable tilt angle. This allows board-shaped hardware such as the motherboard to be tilted and fixed at the optimal viewing angle (such as 30-60 degrees). The conversion of the placement board from a horizontal storage state to a tilted display state is automatically driven by the translation and expansion action, realizing the automatic switching between the protective posture and the optimal viewing posture. This allows students in the back row to easily see the full view and layout of the board, solving the problem of obstructed vision when statically laid flat, and improving the efficiency of teachers' teaching.

[0031] 4. Each placement board has an integrated LED light at the bottom controlled by a mechanical switch. When the placement board is in a parallel state, the switch is pressed by the pressure block, turning off the light. This is energy-saving and safe. The switch is released and the LED light is turned on only when the board is unfolded and tilted to the display angle. This intelligent linkage ensures that the light is accurately and evenly illuminating the tilted board surface, enhancing the visibility of details such as interfaces and chip text, overcoming the limitations of ambient light, and improving the professionalism of teaching.

[0046] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0047] This application discloses a support frame for computer hardware teaching demonstrations.

[0048] Reference Figures 1 to 4 This invention relates to an educational support frame, specifically a support frame for computer hardware teaching demonstrations. It includes a support base 1 and a support cylinder 2 fixedly connected within the support base 1. The bottom of the support base 1 is fixedly equipped with self-locking casters. A control panel is located on the outer side of the support base 1. The bottom of the support cylinder 2 is fixed to the inner wall of the support base 1. A carrying box 3 is slidably connected to the outer wall of the support cylinder 2. The carrying box 3 contains an upper chamber 31 and a lower chamber 32, both of which are annular. The upper chamber 31 contains a number of radially sliding placement boxes 4 arranged in a circular array. Three placement boxes 4 are shown in the figure. The placement boxes 4 are used to accommodate non-plate-shaped computer hardware (such as fans, mice, and casings). The lower chamber 32 contains a number of placement plates 5 arranged in a circular array. The placement plates 5 are used to accommodate plate-shaped computer hardware (such as motherboards, CPUs, and memory). Both the placement boxes 4 and the placement plates 5 are made of transparent acrylic sheets, and both the surfaces of the placement boxes 4 and the placement plates 5 are covered with anti-static film.

[0049] A control component 6 is installed inside the support cylinder 2. The control component 6 is used to drive the carrier box 3 to rise along the support cylinder 2 and drive it to rotate around the axis of the support cylinder 2 after rising to a predetermined height. A handle 7 is fixedly installed at the top of the support cylinder 2. The two ends of the handle 7 are of different lengths. An unfolding component 8 is installed in the upper chamber 31. The unfolding component 8 is used to drive all the placement boxes 4 to move outward radially synchronously by a first preset distance when the carrier box 3 rotates. An unfolding component 9 is installed in the lower chamber 32. The unfolding component 9 is used to drive all the placement plates 5 to move outward radially synchronously by a second preset distance when the carrier box 3 rotates. The second preset distance is longer than the first preset distance. During the movement, the placement plates 5 are driven to change from a horizontal state to an inclined state, thereby forming a stepped display layout with the unfolded placement boxes 4 in the upper layer. The shape of the placement cavity of the placement plate 5 is designed according to the shape of the plate-shaped computer hardware to avoid displacement of the plate-shaped hardware after the placement plate 5 is tilted.

[0050] In its stowed state, the entire support frame is a compact box shape. Upon activation, the control component 6 first drives the carrier box 3 to rise vertically along the support cylinder 2, fully extending it out of the support base 1. After reaching the predetermined height, the control component 6 continues to drive the carrier box 3 to rotate horizontally around the axis of the support cylinder 2. During the rotation, the handle 7 fixed to the support cylinder 2 provides a reaction fulcrum for the unfolding component 1 8 and unfolding component 2 9. The unfolding component 1 8 then moves, driving all the placement boxes 4 made of transparent acrylic sheets and covered with anti-static film in the upper chamber 31 to slide outward radially a first preset distance, used to display non-plate hardware such as fans and hard drives. At the same time, the unfolding component 2 9 starts working, first driving all the placement plates 5 made of transparent acrylic sheets and covered with anti-static film in the lower chamber 32 to slide outward radially a longer second preset distance. Then, the continuous movement of the unfolding component 2 9 causes the placement plates 5 to change from a horizontal stowed state to an inclined display state, thus forming a stepped three-dimensional display layout without visual obstruction together with the upper placement boxes 4, which is convenient for observing plate hardware such as motherboards and graphics cards from multiple angles.

[0051] Reference Figures 2 to 4The control component 6 includes a drive member 61 fixedly installed inside the support base 1. The mounting end of the drive member 61 is fixed to the inner wall of the support base 1. The drive end of the drive member 61 is provided with a bevel gear set 62, which is formed by two bevel gears. One bevel gear is fixed to the drive end of the drive member 61 via a coupling, and the other bevel gear is fixedly connected to a threaded rod 63 located inside the support cylinder 2. The threaded rod 63 is coaxially arranged with the support cylinder 2, and the bottom end of the threaded rod 63 passes through the interior of the support base 1 and is rotatably connected. The outer wall of the support cylinder 2 has a through-hole opening. The control groove 64 is inverted L-shape and consists of a horizontal end and a vertical section. A movable block 65 is threadedly connected to the threaded rod 63. The movable block 65 extends on both sides and slides inside the control groove 64. The extended sections on both sides of the movable block 65 are fixedly connected to the inner side of the bearing box 3. Two corrugated pipes 66 are sleeved on the support cylinder 2. The top end of one corrugated pipe 66 is fixed to the top end of the support cylinder 2, and its bottom end is fixed to the upper surface of the bearing box 3. The top end of the other corrugated pipe 66 is fixed to the bottom surface of the bearing box 3, and its bottom end is fixed to the inner wall of the support base 1.

[0052] Before use, the carrier box 3 is in the storage position, and the moving block 65 is located at the lower end of the vertical section of the control groove 64. When the drive unit 61 is activated, power is transmitted through the bevel gear set 62, causing the threaded rod 63 to rotate. The moving block 65, meshing with the threaded rod 63, is constrained by the vertical section of the control groove 64, converting the rotational motion into linear motion. This causes the carrier box 3, which is fixed to it, to rise smoothly along the support cylinder 2. The two bellows 66 extend accordingly. When the carrier box 3 rises to the top, the moving block 65 moves precisely to the inflection point where the control groove 64 changes from vertical to horizontal. The drive unit 61 continues... During operation, under the constraint of the horizontal section of the control groove 64, the moving block 65 drives the bearing box 3 to rotate horizontally around the axis of the support cylinder 2, entering the unfolding stage. Throughout the entire lifting and rotation process, the bellows 66 always covers the moving parts, playing a protective and dustproof role. At the inflection point of the moving block 65 reaching the control groove 64, a polyurethane buffer pad is set to eliminate the mechanical impact generated at the moment of conversion from lifting motion to rotational motion, and to prevent the hardware from becoming loose due to vibration. The moving block 65 is made of polyoxymethylene (POM) material, which has self-lubricating properties and can effectively reduce the noise of the threaded transmission.

[0053] Reference Figures 4 to 10The unfolding component 8 includes a first frame 81 that slides within the upper chamber 31. The inner cavity of the first frame 81 has three fan-shaped sections arranged in a circumferential array. The upper surface of the first frame 81 has several first parallel grooves 82 arranged in a circumferential direction. Three first parallel grooves 82 are shown in the figure. The carrier box 3 has first limiting grooves 83 arranged in a circumferential direction. The first limiting grooves 83 are located at the top of the upper chamber 31. First circular grooves are slidably connected to both the first limiting grooves 83 and the first parallel grooves 82. The first cylindrical column 84 is adapted to the dimensions of the first parallel groove 82 and the first limiting groove 83 to prevent the placement box 4 from shifting when it moves. The bearing box 3 is provided with a first arc groove 85 with an angle of 90 degrees. A first limiting rod 86 is slidably connected to the first arc groove 85 and fixedly connected to the inner side of the first frame 81. The handle 7 is provided with a first round hole 87 adapted to the size of the first limiting rod 86. The first round hole 87 is used to limit the rotation of the first frame 81.

[0054] When the first limiting rod 86 is inserted into the first circular hole 87 of the handle 7, the first frame 81 is locked and no longer rotates with the carrier box 3. Thereafter, relative motion is generated between the continuously rotating carrier box 3 and the fixed first frame 81. Since each placement box 4 is simultaneously slidably connected to the first limiting groove 83 of the carrier box 3 and the first parallel groove 82 of the first frame 81 through the first cylinder 84, this relative motion forces the first cylinder 84 to move along the combined path determined by the first limiting groove 83 and the first parallel groove 82, that is, to drive all placement boxes 4 to move synchronously and stably in a straight line outward in the radial direction until they are fully unfolded.

[0055] Reference Figures 4 to 10 The second component 9 includes a second frame 91 that slides within the lower chamber 32. The inner cavity of the second frame 91 has four squares arranged in a circumferential array. Several second parallel grooves 92 are arranged in a circumferential array on the second frame 91. Four second parallel grooves 92 are shown in the figure. The carrier box 3 has second limiting grooves 93 arranged in a circumferential array on its surface. The second limiting grooves 93 are located at the top of the lower chamber 32. Second cylinders 94 are slidably disposed within both the second limiting grooves 93 and the second parallel grooves 92. The dimensions of the second cylinders 94 are the same as those of the second limiting grooves 93. The dimensions of the second parallel groove 92 are adapted to prevent displacement of the second cylinder 94. A second arc groove 95 is provided on the bearing box 3, and the angle of the second arc groove 95 is also set to ninety degrees. A second limiting rod 96 is slidably arranged in the second arc groove 95. The second limiting rod 96 is fixedly connected to the inner side of the second frame 91. A second circular hole 910 adapted to the size of the second limiting rod 96 is provided on the handle 7. The second circular hole 910 is opened corresponding to the position of the second limiting rod 96. The second cylinder 94 achieves the tilting of the placement plate 5 through the angle adjustment structure. The inner wall of the first frame 81 is slidably connected to the outer wall of the placement box 4, and the inner wall of the second frame 91 is slidably connected to the outer side of the placement plate 5.

[0056] The angle adjustment structure includes a sloping groove 98 opened in the second frame 91, a slide rod 99 slidably connected in the sloping groove 98, and the slide rod 99 rotatably connected to the inside of the placement plate 5. A slide plate 97 is hinged to the end of the placement plate 5 away from the carrier box 3. The bottom of the second cylinder 94 is fixedly connected to the end of the slide plate 97 near the carrier box 3. The bottom of the slide plate 97 is slidably connected to the inner wall of the second frame 91. The sloping groove 98 is tilted at an angle of 35°±5° and has a vertical lift of 25mm, which can ensure that the computer hardware presents a golden viewing angle between 30° and 60° after unfolding, specifically 35°.

[0057] Before the carrier box 3 rotates, the second limiting rod 96 is inserted into the second round hole 910 of the handle 7, locking the second frame 91. The relative movement between the carrier box 3 and the second frame 91 forces the second cylinder 94, which slides simultaneously in the second limiting groove 93 and the second parallel groove 92, to move radially. The second cylinder 94 drives the slide plate 97, which is fixed to it, to slide radially along the second frame 91. The slide plate 97 pushes the hinge end of the placement plate 5 to translate outward. At the same time, the slide rod 99, which is fixed to the free end of the placement plate 5, slides in the inclined groove 98 of the second frame 91. The inclined trajectory of the inclined groove 98 forces the slide rod 99 to generate a vertical displacement while moving radially, thereby converting the radial translation of the slide plate 97 into the rotation of the placement plate 5 around the hinge point, realizing the automatic change of the posture of the placement plate 5 from horizontal to inclined. The sliding connection between the first frame 81 and the placement box 4, and between the second frame 91 and the placement plate 5, ensures smooth movement.

[0058] Reference Figure 9 , Figure 10 Two LED lights 54 are fixedly installed inside the slide plate 97. The LED lights 54 are located below the placement plate 5. A switch 52 for controlling the on and off of the LED lights 54 is fixedly connected inside the slide plate 97. A spring 53 is provided on the outer sleeve of the switch 52. The bottom end of the spring 53 is fixedly connected to the slide plate 97. A pressure block 51 that moves according to the state of the placement plate 5 is fixedly connected to the top end of the spring 53.

[0059] When the placement plate 5 is in a horizontally retracted state, its weight presses down on the pressure block 51, compressing the spring 53 and triggering the switch 52 to the open state, turning off the LED light 54 inside the slide plate 97. During the unfolding process, as the placement plate 5 is pushed by the slide plate 97 and begins to tilt, the pressure of the plate on the pressure block 51 gradually decreases. Once the tilt angle reaches a certain value, the elastic force of the spring 53 lifts the pressure block 51 back to its original position, and the switch 52 automatically closes, connecting the circuit. The LED light 54 immediately lights up, providing supplementary lighting from below for the tilted plate-shaped hardware, clearly illuminating its surface details. When retracting, the placement plate 5 returns to a horizontal position and presses down on the pressure block 51 again, automatically turning off the LED light 54.

[0060] Reference Figures 7 to 10Inside the placement box 4, there are several magnets 41 fixedly connected. Magnets 42 are attached to magnets 41 and they attract each other. Magnets 42 can be picked up by using an attraction force greater than that between magnets 42 and magnets 41.

[0061] When placing non-plate-shaped or irregular hardware such as mice and fan housings into the placement box 4, depending on the shape and size of the hardware, the movable magnet 42 can be attracted to the magnet 41 fixed to the inner wall of the placement box 4. Together, they form a magnetic clamping point or limiting edge that can be flexibly adjusted in position and spacing, thereby firmly restricting the hardware in a suitable position in the placement box 4 and preventing the hardware from shaking, rolling or tipping over during the movement or unfolding of the support frame.

[0062] Reference Figure 1 , Figure 2 A battery 10 is fixedly installed inside the support base 1. A display screen 11 is fixedly connected to the upper surface of the carrier box 3. The display screen 11 is used for demonstration. The upper surface of the carrier box 3 is provided with a mounting slot 12 for installing computer hardware. The mounting slot 12 is provided with multiple mounting holes to adapt to computer hardware of different sizes.

[0063] The battery 10 inside the support base 1 provides power to the drive components 61, LED lights 54, display screen 11, etc. of the entire device, allowing the support frame to be moved and used without external wires. The battery 10 is located inside the support base 1, which also adds weight to the support base 1 and improves the stability of the support frame. During teaching demonstrations, auxiliary materials such as hardware schematics and disassembly / assembly videos can be played through the display screen 11 on the carrier box 3. The mounting slot 12 can be used to temporarily fix the motherboard to be demonstrated with the CPU and memory plugged in, or to install hardware such as graphics cards upright, making it convenient for the lecturer to hold and explain, and realizing the combination of dynamic demonstration and static display.

[0064] The drive unit 61, battery 10, and display screen 11 are all existing technologies, and their structural principles will not be detailed here. The drive unit 61 can be implemented as a servo motor. The drive unit 61 is equipped with a Hall encoder, and the number of pulses is set through the control panel to precisely control the lifting height and rotation stroke of the carrier box 3. The entire system is powered by the battery 10 built into the box and operated through the control panel integrated on the support base 1. When the user starts the system, the control panel sends a command to the motor driver to drive the motor to rotate. The motor output shaft drives the threaded rod 63 to rotate through the bevel gear set 62. As the threaded rod 63 rotates, the moving block 65 meshing with it is constrained by the control groove 64. The system drives the carrier box 3 to complete a composite motion of rising and then rotating. While the mechanical movement is in progress, electricity is also supplied to the LED lights 54 on each layer and the demonstration display screen 11 on the top through a preset circuit. The movement of the first unfolding component 8 and the second unfolding component 9 is achieved by a purely mechanical interlocking mechanism, without the need for separate electrical control. The LED lights 54 adopt an independent mechanical trigger circuit. When the placement plate 5 is horizontal, the switch 52 is pressed and the circuit is broken. When it is tilted and raised, the switch 52 is reset and closed under the action of the spring 53, automatically lighting up the LED lights 54, thereby achieving the intelligent lighting effect of lighting up as soon as it is unfolded. The entire system realizes the synchronous coordination from the issuance of a single command to the mechanical sequence unfolding and the intelligent opening and closing of the circuit.

[0065] It should be noted that a perforated conductive slip ring is added at the connection between the threaded rod 63 and the bearing box 3. The power line of the battery 10 is connected to the slip ring stator through the central hollow hole of the threaded rod 63, and the rotor rotates with the bearing box 3 to achieve unobstructed power supply.

[0066] The implementation principle of a support frame for computer hardware teaching demonstration in this application embodiment is as follows: In the storage state, the entire device is a compact box, and all hardware is classified and stored in the carrier box 3. When the display is started, the user activates the drive component 61, the carrier box 3 rises first, revealing all display layers, the carrier box 3 begins to rotate, triggering the upper and lower layer unfolding components 8 and 9, the upper layer placement box 4 is simultaneously pushed out radially, the lower layer placement plate 5 is automatically tilted and raised at the same time as it is pushed out radially, the LED light 54 automatically lights up, all hardware is unfolded in a stepped fan shape, with clear layers, appropriate angles, and adequate lighting, which is convenient for explanation and observation. The drive component 61 is driven in reverse, and each component moves in the opposite order, automatically returning to the initial compact state.

[0067] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
