Description

Technical Field

[0001] This invention relates to the field of automation control technology, specifically to a mechanical lifting knob control display device and interaction method. Background Technology

[0002] Transportation equipment is a device or system used to move objects from one location to another. It comes in various forms, including vehicles, transport equipment, cranes, forklifts, etc., and is widely used in logistics, industrial production, construction, and many other fields. To achieve better loading and unloading, adjustments during transportation, or adaptation to different working scenarios, many transportation devices are equipped with mechanical lifting mechanisms. This allows materials to be smoothly transferred between transport belts at different locations, ensuring the continuity and efficiency of the transportation process. The operation of mechanical lifting mechanisms typically requires a control platform. Through the control platform, operators can operate from a safe location away from the equipment, without direct contact with the mechanical lifting mechanism.

[0003] In existing technology, mechanical lifting knob control display devices are typically placed on the ground or installed on the side of the lifting mechanism base during use. To prevent accidental drops of objects from colliding with the control platform during transport, a protective iron frame is installed on top of the control platform. However, in actual operation, the iron frame obstructs the operator's view, making it difficult for them to clearly see the operation of the control buttons, affecting the smoothness of operation. This is especially true for taller operators, who have larger blind spots and need to crouch down and turn their heads to see the operation buttons more clearly, increasing fatigue and inconvenience. This affects the accuracy of operation and the judgment of the equipment's operating status, ultimately impacting work efficiency.

[0004] Therefore, we propose a mechanical lifting knob control display device to solve the problems mentioned in the background art. Summary of the Invention

[0010] Preferably, a fixing frame is fixedly installed at the top of the rear surface of the adjusting frame, the fixing cylinder is fixedly installed inside the fixing frame, and the top and bottom of the fixing cylinder are provided with double protrusion holes. Three double protrusion blocks are fixedly installed on the outer surface of the flipping rod, and one of the double protrusion blocks is movably embedded inside one of the double protrusion holes.

[0011] Preferably, the stabilizing component includes six stabilizing rotating plates and six tilting limiting plates. Each of the six stabilizing rotating plates has a fixed rod movably embedded inside. Each of the six stabilizing rotating plates has three springs fixedly connected to one outer surface. Each of the six stabilizing rotating plates has two pull ropes fixedly connected to one outer surface. The six pull ropes distributed vertically form a group, and one end of each group of pull ropes is fixedly connected to a movable plate.

[0012] Preferably, the stabilizing component includes two electric actuators, one end of each of the two electric actuators is fixedly mounted on one outer surface of the two movable plates, and the other end of each of the two electric actuators is fixedly mounted with a mounting plate. One outer surface of each of the two mounting plates is fixedly mounted on the outer surfaces of both sides of the adjusting frame. Four arc-shaped plates are fixedly mounted on one outer surface of each of the six stabilizing rotating plates. Four movable holes are opened at the bottom of each of the six tilting limiting plates.

[0013] Preferably, the adjusting frame has two recessed slots inside, and three inclined flip holes are provided on one side of each of the two recessed slots.

The two ends of the six fixing rods are respectively fixedly installed on both sides inside the six inclined flip holes.

[0014] Preferably, three inclined limiting plates are vertically distributed in each of the six inclined limiting plates, forming a group. The two groups of inclined limiting plates are fixedly installed inside the two embedded grooves. One end of each of the two groups of pull ropes passes through the two groups of inclined limiting plates to the outer surfaces of both sides of the adjusting frame. The transport equipment is installed on the top of the lifting equipment. The adjusting frame is connected to the bottom of the front surface of the lifting equipment by bolts.

[0015] An interactive method for a mechanical lifting knob control display device includes the following steps: S1. Commands are input to the PLC controller via the touchscreen, operation buttons, and rotary knob, and the equipment status information can be obtained from the high-resolution display screen. By rotating the rotary knob according to the scale on the dial, the PLC controller precisely controls the operating speed and position of the lifting equipment, ensuring smooth up-and-down movement of the transport equipment. S2. When the lifting and transport equipment is working, the relevant sensors will monitor the status of the equipment in real time and transmit the signals to the signal processor for processing. Then, the signals are fed back to the PLC controller. The PLC controller adjusts the control strategy according to the information fed back by the sensors and sends it to the data storage and high-resolution display screen for data storage and data display respectively. When the sensor detects an abnormality, the alarm is triggered. S3. Start the forward and reverse motors to drive the limit winding rollers to wind up the winding rope. The double-headed fixed ropes drive the limit binding blocks to move upward, which in turn drives the protective components and interactive control components to move upward, so that the flipping plate gradually contacts the flipping top rod. S4. Simultaneously, the top rod is flipped to generate a pushing force on the flipping plate, pressing the flipping block downwards. At the same time, the protective plate rotates and opens, at which point the interactive display area and input area are fully displayed in front of the operator. S5. When the stabilizing plate moves upward, it gradually contacts the stabilizing rotating plates on both sides and generates thrust, causing it to rotate into the tilting flip hole and compress the spring, causing the pull rope to retract. When the stabilizing plate leaves the top of the tilted stabilizing rotating plate, the forward and reverse motors are turned off. At the same time, the stabilizing rotating plate loses thrust. Under the spring's rebound, the stabilizing rotating plate rotates outward from the tilting flip hole to the bottom of the stabilizing plate, supporting the stabilizing plate. S6. Activate the electric actuators on both sides to pull the two moving plates and drive the pull rope to move outward. At the same time, it generates a pulling force on the stabilizing plate, causing it to rotate again into the tilting flip hole. At this time, the stabilizing plate loses its support. S7. Restart the forward and reverse motors to drive the limit winding roller to rotate in the opposite direction and release the winding rope, which will cause the interactive control component to move downward.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, the lifting device's operating speed is controlled by the knob adjuster on the interactive control component, ensuring smooth up-and-down movement of the transport equipment. Starting the forward and reverse motors drives the limit winding rollers to wind up the winding rope. The double-ended fixing rope moves the limit binding block upwards, which in turn moves the protective component and the interactive control component upwards. This causes the flipping plate to gradually contact the flipping top rod, which simultaneously exerts a pushing force on the flipping plate, pressing the flipping block downwards. At the same time, the protective plate rotates and opens, fully exposing the interactive display and input areas to the operator. The cooperation of the protective component, lifting component, and flipping component not only increases the height of the interactive control component but also achieves a combined protective structure. The top protective plate is movable and flippable; adjusting the height while opening the protective plate eliminates visual obstruction, allowing the operator to better control the interactive control component without needing to tilt their head, resulting in a more comfortable operating posture and reduced fatigue.

[0017] 2. In use, this invention allows users to input commands to the PLC controller via a touchscreen, operation buttons, and rotary knob, and obtain equipment status information from a high-resolution display screen. By rotating the rotary knob according to the scale on the dial, the PLC controller controls the flow rate of the hydraulic system in the lifting equipment, thereby precisely controlling the operating speed and position of the lifting equipment and ensuring smooth up-and-down movement of the transport equipment. During operation, relevant sensors monitor the equipment status in real time and transmit signals to a signal processor for processing, then feed them back to the PLC controller. The PLC controller adjusts the control strategy based on the sensor feedback and sends the data to the data storage and high-resolution display screen for data storage and display, respectively. When a sensor detects an abnormality, an alarm is triggered.

[0018] 3. When using this invention, as the stabilizing plate moves upward, it gradually contacts the stabilizing rotating plates on both sides, generating a thrust that causes it to rotate into the inclined flip hole and compress the spring, causing the pull rope to retract. When the stabilizing plate leaves the top of the inclined stabilizing rotating plate, the forward and reverse motors are turned off, and the stabilizing rotating plate loses its thrust. Under the spring's rebound, the stabilizing rotating plate rotates outward from the inclined flip hole to the bottom of the stabilizing plate, supporting the stabilizing plate and thus providing auxiliary support for the interactive control component, improving its stability, reducing the lifting pressure on the lifting component, and allowing the operator to operate the interactive control component stably, reducing swaying and instability, and minimizing impact on operational accuracy.

[0019] 4. When using this invention, the three double-convex blocks correspond to three sets of stable rotating plates at different heights. The height of the flipping rod is adjusted according to the height required for the interactive control component, and the corresponding double-convex blocks are fitted into the double-convex holes at the top. With the cooperation of the flipping component and the lifting component, the height of the interactive control component can be adjusted according to different needs, and the protective plate can be opened.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-12As shown, the present invention provides a technical solution: a mechanical lifting knob control display device, including an adjustment frame 1, a lifting device 2 and a transport device 3. The adjustment frame 1 is provided with an interactive control component 4 and a protective component 5. The top of the adjustment frame 1 is provided with a lifting component 6 and a flipping component 7. The adjustment frame 1 is provided with a stabilizing component 8. The protective component 5 includes a flipping block 503 and two limiting binding blocks 506. A flipping plate 504 is fixedly installed on the rear surface of the flipping block 503, and a protective plate 505 is fixedly installed on the front surface of the flipping block 503. The lifting component 6 includes a limiting winding roller 602. Two winding ropes 603 are provided on the outer surface of the limiting winding roller 602. One end of each winding rope 603 is fixedly connected to a double-headed fixing rope 604.The flipping assembly 7 includes a fixed cylinder 701, with a flipping top rod 703 movably embedded inside the fixed cylinder 701. The interactive control assembly 4 includes an interactive body 401, with maintenance doors 402 bolted to both outer surfaces of the interactive body 401. A rotary adjuster 405, a high-resolution display screen 406, and a touch screen 407 are respectively installed on the front surface of the interactive body 401. An alarm 408 is installed on the front wall inside the interactive body 401. A PLC controller 409, a data storage device 410, a communicator 411, and a signal processor 412 are respectively installed on the rear wall inside the interactive body 401. A stabilizing plate 403 is bolted to the bottom of the interactive body 401. Two limit sliders 404 are fixedly installed on both the front and rear surfaces of the stabilizing plate 403. Two sliding grooves 9 are opened on both sides inside the adjusting frame 1, and the outer surfaces of the four limit sliders 404 are movably embedded in the four sliding grooves 9. Inside, the protective assembly 5 also includes a side wing protective frame 501. A central rod 502 is fixedly installed inside the side wing protective frame 501. The outer surfaces of two limiting binding blocks 506 are respectively fixedly installed on the outer surfaces of the two sides of the side wing protective frame 501. A flipping block 503 is movably sleeved on the outer surface of the central rod 502. The outer surface of the protective plate 505 is movably embedded inside the side wing protective frame 501. The side wing protective frame 501 is sleeved on the outer surfaces of the interactive body 401 and the two maintenance doors 402. The side wing protective frame 501 and the two maintenance doors 402 are connected by bolts. A forward and reverse motor 601 is fixedly installed on one side of the top of the adjusting frame 1. The output end of the forward and reverse motor 601 is fixedly connected to one end of the limiting take-up roller 602. A support block 605 is movably fitted onto the other end of the roller 602. The bottom of the support block 605 is fixedly installed on the other side of the top of the adjusting frame 1. Two double-headed fixing ropes 604 are movably connected to the outer surfaces of two limiting binding blocks 506, respectively. A fixing frame 705 is fixedly installed at the top of the rear surface of the adjusting frame 1. A fixing cylinder 701 is fixedly installed inside the fixing frame 705. The top and bottom of the fixing cylinder 701 are both provided with double protruding holes 702. Three double protruding locking blocks 704 are fixedly installed on the outer surface of the flipping top rod 703. One of the double protruding locking blocks 704 is movably embedded inside one of the double protruding holes 702. The transport device 3 is installed on the top of the lifting device 2. The adjusting frame 1 is connected to the bottom of the front surface of the lifting device 2 by bolts.

[0024] In this embodiment, during use, the lifting device 2, the transport device 3, the high-resolution display screen 406, the touch screen 407, the alarm 408, the data storage device 410, the communicator 411, the signal processor 412, the forward and reverse motor 601, the electric push rod 802, and the PLC controller 409 are electrically connected. Various sensors installed on the lifting device 2 and the transport device 3 are electrically connected to the PLC controller 409. Control buttons are located on both sides of the touch screen 407. The front surface of the interactive body 401 is mainly divided into a display area and an input area. The display area includes the high-resolution display screen 406, and the input area includes the touch screen 407, operation buttons, and a rotary knob adjuster 405. Operators can input commands to the PLC controller 409 through the input area and obtain equipment status information, such as lifting height and transport speed, from the high-resolution display screen 406. The rotary knob adjuster 405 is equipped with a triangular arrow and a dial for convenient and precise rotation by the operator. The rotary knob 405 on the dial generates voltage signals, which are acquired by the PLC controller 409, converted into digital signals, and processed. The rotation of the knob 405 controls the flow rate of the hydraulic system in the lifting device 2, thereby precisely controlling the operating speed and position of the lifting device 2. During operation, relevant sensors monitor the status of the equipment in real time and transmit signals to the signal processor 412. The signal processor 412 amplifies, filters, and performs analog-to-digital conversion on the signals, then feeds the relevant information back to the PLC controller 409. The PLC controller 409 adjusts its control strategy based on the sensor feedback. Simultaneously, the PLC controller 409 sends the received information to the data storage 410 and the high-resolution display screen 406 for data storage and display, respectively. When the PLC controller 409 receives abnormal information from the sensors, it activates the alarm 408 to provide an alarm notification. The double-headed fixing rope 604 has two ends at its bottom. The double-headed fixing rope 604 is tied to two limiting binding blocks 506 respectively, connecting the lifting component 6 and the protective component 5 together. The forward and reverse motor 601 is started, and the output end of the forward and reverse motor 601 drives the limiting winding roller 602 to rotate, winding the two winding ropes 603 and shortening the length of the winding ropes 603. This causes the two double-headed fixing ropes 604 to drive the limiting binding blocks 506 to move upward, thereby driving the protective component 5 and the interactive control component 4 to move upward. At the same time, the stabilizing plate 403 moves inside the adjusting frame 1, and the four limiting sliders 404 slide upward inside the corresponding slide grooves 9, driving the protective plate 505, the flipping block 503 and the flipping plate 504 to move upward together. The bottom end of the flipping top rod 703 is located at the top of the flipping plate 504. As the flipping plate 504 moves, it will gradually contact the bottom end of the flipping top rod 703.When the stabilizing plate 403 moves to the top of the two lowest stabilizing rotating plates 803, the forward and reverse motors 601 are turned off, and the stabilizing components 8 provide auxiliary support for the interactive control components 4, improving stability. Simultaneously, as the flipping plate 504 moves, the flipping rod 703 generates a pushing force on the top of the flipping plate 504. Under the limit of the central rod 502, the flipping plate 504 gradually rotates and tilts, causing the flipping block 503 and the protective plate 505 to rotate and tilt, causing the protective plate 505 to rotate away from the top of the interactive body 401, becoming a front-high, back-low state. At this time, the display area and input area on the front surface of the interactive body 401 are fully exposed to the operator, no longer obstructed by the protective plate 505, eliminating blind spots. With the cooperation of protective component 5, lifting component 6, and flipping component 7, not only can the height of interactive control component 4 be increased, but a combined protective structure can also be achieved. The top protective plate 505 can be flipped open while adjusting the height, eliminating visual obstruction and allowing operators to better control interactive control component 4 without having to turn their heads. This makes the operating posture more comfortable, reduces fatigue, and does not affect the judgment of operating accuracy, thus improving work efficiency. This solves the problem that when using mechanical lifting knob control display devices, the iron protective frame installed on the top obstructs the operator's view. For some taller operators, the blind spot is larger, and after squatting down, they still need to turn their heads to see clearly, which is uncomfortable, increases fatigue, makes operation inconvenient, affects the judgment of operating accuracy, and thus affects work efficiency. When the interactive control component 4 moves to the required position under the action of the lifting component 6 and completes the relevant operations, and further protection of the interactive control component 4 is required, the flipping rod 703 is rotated, causing the three double-convex blocks 704 to rotate together, so that the double-convex blocks 704 rotate to a state parallel to the double-convex holes 702. Then, the flipping rod 703 is pulled upward, so that its bottom end leaves the outer surface of the flipping plate 504. At this time, the flipping plate 504 loses its pushing force, and the protective plate 505 automatically rotates forward under the action of gravity, covering the top of the interactive body 401 again to protect the interactive control component 4.

[0025] Example 2: Figures 2-5 and Figures 11-12As shown, the stabilizing component 8 includes six stabilizing rotating plates 803 and six tilting limiting plates 805. Each of the six stabilizing rotating plates 803 has a fixing rod 804 movably embedded inside. Three springs 808 are fixedly connected to one outer surface of each of the six stabilizing rotating plates 803. Two pull ropes 806 are fixedly connected to one outer surface of each of the six stabilizing rotating plates 803. Six pull ropes 806 arranged vertically form a group, and one end of each group of pull ropes 806 is fixedly connected to a movable plate 807. The stabilizing component 8 includes two electric actuators 802 and two electric actuators 803. One end of each of the two electric push rods 802 is fixedly installed on one side of the outer surface of the two movable plates 807. The other ends of each of the two electric push rods 802 are fixedly installed with mounting plates 801. One side of the outer surface of each of the two mounting plates 801 is fixedly installed on both sides of the outer surface of the adjusting frame 1. Four arc-shaped plates 809 are fixedly installed on one side of each of the six stabilizing rotating plates 803. Four movable holes 810 are opened at the bottom of each of the six tilting limiting plates 805. The outer surfaces of the multiple arc-shaped plates 809 are movably embedded inside the multiple movable holes 810. Two recessed grooves 11 are opened inside the adjusting frame 1. Each of the two recessed slots 11 has three inclined rotating holes 10 on one side. The outer surfaces of the six stabilizing rotating plates 803 are movably embedded in the six inclined rotating holes 10. The two ends of the six fixing rods 804 are fixedly installed on both sides inside the six inclined rotating holes 10. The bottoms of the six stabilizing rotating plates 803 are in contact with the interior of the six inclined limiting plates 805. Multiple springs 808 are arranged in groups of three horizontally distributed springs 808. One end of each of the six groups of springs 808 is fixedly installed on the inner wall of one side of the six inclined limiting plates 805. Three inclined limiting plates 805 are distributed vertically in each group. Two groups of inclined limiting plates 805 are fixedly installed inside the two embedded grooves 11. One end of each of the two pull ropes 806 passes through the two groups of inclined limiting plates 805 to the outer surfaces of both sides of the adjusting frame 1. A stabilizing plate 403 is bolted to the bottom of the interactive body 401. Two limiting sliders 404 are fixedly installed on the front and rear surfaces of the stabilizing plate 403. Two sliding grooves 9 are opened on both sides inside the adjusting frame 1. The outer surfaces of the four limiting sliders 404 are movably embedded in the four sliding grooves 9. The flipping component 7 includes a fixed cylinder 701. A flipping top rod 703 is movably embedded inside the fixed cylinder 701.

[0026] In this embodiment, during use, the stabilizing component 8 is equipped with six stabilizing rotating plates 803, three on each side, with two stabilizing rotating plates 803 in the horizontal direction forming a group, for a total of three groups, as shown below. Figure 11As shown, the three sets of stabilizing rotating plates 803 have different heights, and both sides of the stabilizing rotating plates 803 are arc-shaped. When the lifting assembly 6 pulls the stabilizing plate 403 upward, it gradually contacts the stabilizing rotating plates 803 on both sides and generates a pushing force on the stabilizing rotating plates 803 on both sides. Under the limit of the fixed rod 804, the stabilizing rotating plates 803 on both sides rotate about the fixed rod 804 as the axis into the tilting flip hole 10. At the same time, it drives the arc-shaped plate 809 to rotate in the movable hole 810 and squeeze the spring 808, causing the pull rope 806 to retract. When the stabilizing plate 403 leaves the top of the tilted stabilizing rotating plates 803 on both sides, the forward and reverse motor 60 is turned off. 1. At the same time, the stabilizing rotating plates 803 on both sides lose their thrust. Under the rebound of the spring 808, the stabilizing rotating plates 803 are pushed again, causing them to rotate outward from the inside of the inclined flip hole 10 and return to the initial state. At this time, the top of the stabilizing rotating plates 803 on both sides rotates to the bottom of the stabilizing plate 403, supporting the stabilizing plate 403, thereby providing auxiliary support for the interactive control component 4, improving its stability, reducing the lifting pressure of the lifting component 6, and enabling the operator to operate stably on the interactive control component 4, reducing swaying and instability, and affecting the accuracy of operation. When it is necessary to restore the interactive control component 4 to its initial state, the electric push rods 802 on both sides are activated, which pulls the two moving plates 807 to move and drives the corresponding take-up rope 806 to move outward. At the same time, a pulling force is generated on the stabilizing rotating plate 803, causing it to rotate back into the tilting flip hole 10. At this time, the stabilizing plate 403 loses its support. The forward and reverse motors 601 are activated again, which drives the limit take-up roller 602 to rotate in the opposite direction and release the take-up rope 603, so that the interactive control component 4 can move downward.

[0027] Example 3: Figures 2-7 and Figures 11-12 As shown, the adjustment frame 1 is internally equipped with an interactive control component 4 and a protective component 5. The top of the adjustment frame 1 is equipped with a lifting component 6 and a flipping component 7. The adjustment frame 1 also contains a stabilizing component 8, which includes six stabilizing rotating plates 803 and six tilting limiting plates 805. Each of the six stabilizing rotating plates 803 has a fixed rod 804 movably embedded inside. Three springs 808 are fixedly connected to one outer surface of each of the six stabilizing rotating plates 803, and two pull ropes 806 are fixedly connected to one outer surface of each of the six stabilizing rotating plates 803. The pull ropes 806 are vertically distributed in six... Each pull rope 806 forms a group, and one end of each group of pull ropes 806 is fixedly connected to a movable plate 807. The stabilizing component 8 includes two electric push rods 802. One end of each electric push rod 802 is fixedly installed on the outer surface of one side of each of the two movable plates 807. The other end of each electric push rod 802 is fixedly installed with a mounting plate 801. The top and bottom of the fixed cylinder 701 are provided with double protrusion holes 702. Three double protrusion blocks 704 are fixedly installed on the outer surface of the flipping rod 703. One of the double protrusion blocks 704 is movably embedded in the interior of one of the double protrusion holes 702.

[0028] In this embodiment, during use, three double-convex locking blocks 704 are installed on the outer surface of the flipping rod 703, corresponding to three sets of stabilizing rotating plates 803 at different heights. The height of the flipping rod 703 is adjusted according to the required height of the interactive control component 4, and the corresponding double-convex locking blocks 704 are fitted into the double-convex holes 702 at the top. With the cooperation of the flipping component 7 and the lifting component 6, the height of the interactive control component 4 can be adjusted according to different needs, and the protective plate 505 can be opened. The structure of the double-convex locking blocks 704 is as follows: Figure 7 As shown, the width between the upper and lower convex corners of the double convex block 704 matches the width of the double convex hole 702. Rotating the flipping rod 703 causes the double convex block 704 to rotate, making it flush with the double convex hole 702. This allows the flipping rod 703 to be pulled upward, moving the next double convex block 704 upward into the upper double convex hole 702. Then, rotating the flipping rod 703 causes the double convex block 704 to rotate into an interlaced shape with the double convex hole 702, tightly locking it in the double convex hole 702. This fixes the adjusted flipping rod 703 in the fixing cylinder 701, making it easier to open the protective plates 505 of different heights, making it more flexible and convenient.

[0029] The method of use and working principle of this invention are as follows: The front surface of the interactive body 401 is mainly divided into a display area and an input area. The display area includes a high-resolution display screen 406, and the input area includes a touch screen 407, operation buttons, and a rotary regulator 405. Operators can input commands to the PLC controller 409 through the input area and obtain equipment status information from the high-resolution display screen 406. Rotating the rotary regulator 405 according to the scale on the dial generates voltage signals. These signals are collected by the PLC controller 409, converted into digital signals, and processed. The rotation of the rotary regulator 405 then controls the flow rate of the hydraulic system in the lifting device 2, thereby precisely controlling the operating speed and position of the lifting device 2. When the lifting device 2 and the transport device 3 are working, relevant sensors monitor the equipment status in real time and transmit signals to the signal processor 412 for processing. The relevant information is then fed back to the PLC controller 409. The PLC controller 409 adjusts the control strategy based on the sensor feedback information and simultaneously sends the received information to the data storage 410 and the high-resolution display screen 406 for data storage and display, respectively. When the PLC controller 409 receives an abnormal information from the sensor, it will control the alarm 408 to sound. The forward and reverse motor 601 is started, driving the limit winding roller 602 to rotate and wind up the two winding ropes 603, shortening their length. This causes the two double-ended fixing ropes 604 to move the limit binding block 506 upwards, which in turn moves the protective component 5 and the interactive control component 4 upwards. As the stabilizing plate 403 moves upward, it gradually contacts the stabilizing rotating plates 803 on both sides and generates a thrust, causing the stabilizing rotating plates 803 to rotate into the inclined flip hole 10. At the same time, it drives the arc plate 809 to rotate in the movable hole 810 and compress the spring 808, causing the pull rope 806 to retract. When the stabilizing plate 403 leaves the top of the stabilizing rotating plates 803 after they have tilted on both sides, the forward and reverse motor 601 is turned off. At the same time, the stabilizing rotating plates 803 on both sides lose their thrust. Under the rebound of the spring 808, they generate a thrust on the stabilizing rotating plates 803 again, causing them to rotate outward from the inclined flip hole 10 and return to the initial state. At this time, the top of the stabilizing rotating plates 803 on both sides rotates to the bottom of the stabilizing plate 403, supporting the stabilizing plate 403. When the interactive control component 4 moves, it drives the protective plate 505, the flip block 503 and the flip plate 504 to move upward together. The flip plate 504 contacts the bottom end of the flip rod 703, and the flip rod 703 generates a pushing force on the flip plate 504. Under the limit of the center rod 502, the flip plate 504 is pressed downward. With the connection of the flip block 503, the protective plate 505 rotates away from the top of the interactive body 401 and becomes a state of front high and back low. At this time, the display area and input area on the front surface of the interactive body 401 are fully exposed to the operator, and the blind spot is eliminated because the protective plate 505 is no longer blocked.When the interactive control component 4 moves to the required position under the action of the lifting component 6 and completes the relevant operations, and further protection of the interactive control component 4 is required, the flipping rod 703 is rotated, causing the three double-convex blocks 704 to rotate together, so that the double-convex blocks 704 rotate to a state parallel to the double-convex holes 702. Then, the flipping rod 703 is pulled upward, so that its bottom end leaves the outer surface of the flipping plate 504. At this time, the flipping plate 504 loses its pushing force, and the protective plate 505 automatically rotates forward under the action of gravity, covering the top of the interactive body 401 again to protect the interactive control component 4.
