[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] Reference Figures 1 to 4 This application provides a vocational college employment guidance exhibition board, including a main board 1 and a support 4. An extension component 2 is provided on the outer side of the main board 1, and an angle adjustment component 3 is provided between the main board 1 and the support 4. An adjustment plate 6 is fixedly installed at the bottom of the main board 1 and is hinged to the top of the support 4. A controller 5 is fixedly installed on the front of the support 4. The extension component 2 includes left and right extension plates 22, which are slidably connected to the left and right sides inside the main board 1, respectively. An upper and lower extension plates 21 are slidably connected to the front of the main board 1. Two moving blocks 23 are fixedly installed on the back of the upper and lower extension plates 21, and two sliders 25 are slidably connected to the back of the main board 1. A connecting plate 24 is fixedly installed between the upper and lower moving blocks 23 and the sliders 25.
[0026] Two pairs of side plates 26, corresponding to each other, are fixedly installed on the back of the main body plate 1. A screw 27 is rotatably connected between the upper and lower side plates 26 on the left side, and the screw 27 is screwed through the interior of the left slider 25. A first motor 28 is fixedly installed at the bottom of the left side plate 26, and the output shaft of the first motor 28 movably passes through the interior of the side plate 26 and is fixedly connected to the screw 27. A slide rod 210 is fixedly installed between the upper and lower side plates 26 on the right side, and the right slider 25 is slidably connected to the outside of the slide rod 210. A gear 211 is rotatably connected inside the main body plate 1. A rack 212 is fixedly installed on the inner side of each of the two left and right extension plates 22. The left rack 212 meshes with the gear 211 above, and the right rack 212 meshes with the gear 211 below. A self-locking motor 29 is fixedly installed on the back of the main body plate 1, and the output end of the self-locking motor 29 movably passes through the inner wall of the main body plate 1 and is fixedly connected to the front gear 211.
[0027] In this embodiment, the expansion component 2 includes an upper and lower expansion plate 21 and a left and right expansion plate 22, which realizes the multi-dimensional expansion of the exhibition board in the upper and lower and left and right directions.
[0028] When the exhibition panel needs to be expanded vertically, the controller 5 sends a command to the first motor 28, which starts and its output shaft drives the screw 27 to rotate. Since the screw 27 is screwed through the inside of the left slider 25, the left slider 25 will move in a straight line along the screw 27. At the same time, the right slider 25 slides on the outside of the slide bar 210, which plays a guiding and stabilizing role. The left and right sliders 25 are connected to the moving block 23 on the back of the upper and lower expansion plates 21 through the connecting plate 24. The movement of the sliders 25 drives the upper and lower expansion plates 21 to slide up and down on the front of the main body plate 1, thereby realizing the expansion of the exhibition panel in the vertical direction.
[0029] When expanding in the left and right directions, the controller 5 controls the self-locking motor 29 to start. The output end of the self-locking motor 29 drives the gear 211 to rotate. Because the racks 212 on the inner sides of the two left and right expansion plates 22 are respectively engaged with the gear 211 above and below, when the gear 211 rotates, it will drive the racks 212 that are engaged with it to move, thereby causing the two left and right expansion plates 22 to slide to the left and right sides of the main plate 1 respectively, completing the expansion of the exhibition plate in the left and right directions. This method of simultaneous expansion in the up and down and left and right directions, compared with the previous technology which only expanded left and right, greatly increases the display area and significantly improves the expansion effect.
[0030] Reference Figures 1 to 4 In one aspect of this embodiment, the angle adjustment assembly 3 includes extension plates 31, which are fixedly mounted on the back of the bracket 4. There are three extension plates 31 in total. An electric push rod 32 is hinged between the top of the middle extension plate 31 and the back of the main body plate 1, and reinforcing telescopic rods 33 are hinged between the top of the two side extension plates 31 and the back of the main body plate 1. The controller 5 is electrically connected to the extension plates 31, and the controller 5 is electrically connected to the first motor 28 and the self-locking motor 29.
[0031] In this embodiment, the angle adjustment component 3 mainly consists of an extension plate 31, an electric actuator 32, and a reinforcing telescopic rod 33. When it is necessary to adjust the angle of the main body plate 1, the controller 5 sends a control signal to the electric actuator 32, and the electric actuator 32 starts to work, and its telescopic rod moves in extension and retraction. Since the top of the middle extension plate 31 is hinged to the back of the main body plate 1 with the electric actuator 32, and the top of the two side extension plates 31 is hinged to the back of the main body plate 1 with the reinforcing telescopic rod 33, the extension and retraction of the electric actuator 32 will drive the main body plate 1 to rotate around the hinge point with the adjustment plate 6. At the same time, the reinforcing telescopic rod 33 plays an auxiliary support and stabilizing role, ensuring the stability of the main body plate 1 during the angle adjustment process. In this way, the angle of the exhibition plate can be flexibly adjusted according to the actual use scenario and the audience's viewing angle requirements. Compared with the situation in the background technology where the angle cannot be effectively adjusted, the usage effect and display experience are improved.
[0032] Considering that the vocational education employment guidance exhibition board needs to precisely control multiple components such as expansion component 2 and angle adjustment component 3, and also needs to have a certain anti-interference capability and stability, Siemens S7-1200 series PLC can be selected as controller 5. This series of PLCs has the characteristics of small size, powerful function and flexible programming, which can meet the control requirements of the exhibition board.
[0033] In the actual control process, the PLC is first connected to the control buttons or sensors through its input ports. Users can issue commands such as expansion and angle adjustment by operating the control buttons. The sensors can provide real-time feedback on the status information of each component, such as the position of the expansion plate and the extension length of the electric actuator 32. The PLC has a pre-written control program. When it receives an expansion command from the user, the PLC sends control signals to the first motor 28 and the self-locking motor 29 through its output ports. The first motor 28 drives the screw 27 to rotate, thereby raising and lowering the upper and lower expansion plates 21. The self-locking motor 29 drives the gear 211 to rotate, thereby extending the left and right expansion plates 22. When it receives an angle adjustment command, the PLC sends a corresponding control signal to the electric actuator 32 to adjust the extension amount of the electric actuator 32, thereby driving the main plate 1 to rotate around the hinge point to a suitable angle. At the same time, the PLC monitors and adjusts the operating status of each component in real time based on the information fed back by the sensors, ensuring the stable and efficient operation of the exhibition board.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] Working principle: When the exhibition board needs to be expanded vertically, the controller 5 sends a command to the first motor 28, the first motor 28 starts, and its output shaft drives the screw 27 to rotate. Since the screw 27 is screwed through the inside of the left slider 25, the left slider 25 will move in a straight line along the screw 27. At the same time, the right slider 25 slides on the outside of the slide bar 210, which plays a guiding and stabilizing role. The left and right sliders 25 are connected to the moving block 23 on the back of the upper and lower expansion plates 21 through the connecting plate 24. The movement of the sliders 25 drives the upper and lower expansion plates 21 to slide up and down on the front of the main body plate 1, thereby realizing the expansion of the exhibition board in the vertical direction.
[0036] When expanding in the left and right directions, the controller 5 controls the self-locking motor 29 to start. The output end of the self-locking motor 29 drives the gear 211 to rotate. Because the racks 212 on the inner sides of the two left and right expansion plates 22 are respectively engaged with the gear 211 above and below, when the gear 211 rotates, it will drive the racks 212 that are engaged with it to move, thereby causing the two left and right expansion plates 22 to slide to the left and right sides of the main plate 1 respectively, completing the expansion of the exhibition plate in the left and right directions. This method of simultaneous expansion in the up and down and left and right directions, compared with the previous technology which only expanded left and right, greatly increases the display area and significantly improves the expansion effect.
[0037] When the angle of the main panel 1 needs to be adjusted, the controller 5 sends a control signal to the electric actuator 32, which then starts to work, and its telescopic rod moves in extension and retraction. Since the top of the middle extension plate 31 is hinged to the back of the main panel 1 by the electric actuator 32, and the top of the two side extension plates 31 is hinged to the back of the main panel 1 by reinforcing telescopic rods 33, the extension and retraction of the electric actuator 32 will cause the main panel 1 to rotate around the hinge point with the adjustment plate 6. At the same time, the reinforcing telescopic rods 33 play an auxiliary support and stabilizing role, ensuring the stability of the main panel 1 during the angle adjustment process. In this way, the angle of the exhibition panel can be flexibly adjusted according to the actual use scenario and the audience's viewing angle requirements. Compared with the situation in the background technology where the angle cannot be effectively adjusted, the usage effect and display experience are improved.
