Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] This utility model provides a technical solution:
[0032] Please see Figures 1 to 6 An ultra-thin electric telescopic platform includes a base 1, a cover plate 2 detachably installed on the top of the base 1, a movable plate 3 slidably connected to the base 1 on the top of the cover plate 2, guide mechanisms on the left and right sides of the base 1, and a transmission mechanism in the middle of the upper surface of the base 1.
[0033] The guiding mechanism includes a guide groove 6 and a guide wheel 7. The guide groove 6 or the guide wheel 7 is located on both sides of the base 1, and the guide wheel 7 or the guide groove 6 is located on both sides of the movable plate 3. The movable plate 3 forms a sliding fit with the base 1 through the guiding structure. The movable plate supports the guide wheel 24 at the front or rear end of the base 1. A fixed frame 5 is fixedly installed inside the base 1, and a fixed plate 4 is fixedly installed at the front end of the fixed frame 5.
[0034] By adopting the above technical solution, the electric telescopic platform can be adjusted according to requirements during design and use. When the base 1 is equipped with guide groove 6, the moving plate 3 is equipped with guide wheel 7; when the base 1 is equipped with guide wheel 7, the moving plate 3 is equipped with guide groove 6, and the guide wheel 7 slides in the guide groove 6. At the same time, the position of the moving plate support guide wheel 24 changes according to the setting of guide wheel 7 and guide groove 6. When the base 1 is equipped with guide groove 6 and the moving plate 3 is equipped with guide wheel 7, the moving plate support guide wheel 24 is set on the front side of the base 1; otherwise, it is set on the rear side. When the electric telescopic platform is installed, the fixing plate 4 is fixed in a suitable position by bolts, etc., and the base 1 is stably supported by the fixing frame 5. When telescopic work is performed, the transmission mechanism is activated, and the operation of the transmission mechanism can drive the moving plate 3 to move. The moving plate 3 can move on the base 1 through the guide wheel 7 and guide groove 6, thereby ensuring the stability of the platform during telescopic movement. At the same time, the moving plate support guide wheel 24 can play a supporting and guiding role, further ensuring the stability of the moving plate 3 during movement. The guide wheel 7 is made of plastic-coated nylon to reduce noise generation during operation.
[0035] Specifically, such as Figures 1 to 4 , Figure 7 and Figure 8As shown, the transmission mechanism includes a drive motor 8 fixedly installed on the right side of the front end of the upper surface of the base 1 at the middle position. A motor pulley 9 is fixedly installed at the output end of the drive motor 8. The transmission mechanism also includes a pulley connecting plate 20 or a bearing seat 26 fixedly installed at the front end of the upper surface of the base 1 at the middle position. A transmission support bearing 18 is fixedly installed inside the upper end of the pulley connecting plate 20. A support guide wheel 17 is rotatably installed on the outer side of the adjacent transmission support bearing 18. The support guide wheel 17 can provide stable auxiliary support for the moving plate 3. A first transmission pulley 10 and a second transmission pulley 11 are rotatably installed inside the transmission support bearing 18. A first synchronous belt 13 is embedded on the end face of the first transmission pulley 10. The second transmission pulley 11 is coaxially connected to the first transmission pulley 10. A second synchronous belt 14 is embedded on the end face of the second transmission pulley 11. A limiter 23 is fixedly installed on the upper end face of the base 1 on one side of the second synchronous belt 14. The limiter 23 can limit the extension of the electric telescopic platform. A driven pulley 12 is rotatably installed at the rear end of the middle position of the upper end face of the base 1. A pulley tensioning module 19 is fixedly installed on the upper end face of the base 1 behind the driven pulley 12. The driven pulley 12 is connected to the second synchronous belt 10. The second synchronous belt 14 is rotatably fitted together with the upper end of the second synchronous belt 14.

Pulley fixing plates 15 are fixedly installed on the lower ends of the left and right ends of the movable plate connecting plate 16. The pulley fixing plates 15 rotatably abut against the end face of the base 1. It should be noted that an auxiliary guide wheel is provided near the base 1 on the pulley fixing plate 15 to prevent the movable plate 3 from bending and deforming in the middle when it is subjected to pressure. When the laser TV is pressed on the movable plate 3, the movable plate is subjected to pressure. When the telescopic platform moves back and forth, the auxiliary guide wheel rolls along the upper surface of the base 1. The movable plate connecting plate 16 is fixedly connected to the movable plate 3. It should be noted that a horizontal groove is provided in the middle of the upper surface of the baffle plate 2 to facilitate the connection between the moving plate connecting plate 16 and the moving plate 3. A control plate 22 is fixedly installed on the front end of the base 1. A button 21 is embedded in the front end of the base 1 on one side of the control plate 22. The button 21 is electrically connected to the control plate 22. The control plate 22 is provided with a power interface and a signal synchronization interface, etc. A moving plate connecting plate 16 is provided on the right side of the second synchronization belt 14. The moving plate connecting plate 16 is fixedly installed on the upper surface of the base 1. A fixing frame 5 is fixedly installed inside the base 1. A fixing piece 4 is fixedly installed at the front end of the fixing frame 5.
[0036] By adopting the above technical solution, when the transmission mechanism is energized, the drive motor 8 can drive the motor pulley 9 to rotate. The rotation of the motor pulley 9 can drive the first transmission pulley 10 to rotate via the first synchronous belt 13. The first transmission pulley 10 and the second transmission pulley 11 are coaxially connected, thereby driving the second transmission pulley 11 to rotate. The transmission support bearing 18, the first transmission pulley 10, and the second transmission pulley 11 are supported by the pulley connecting plate 20. The first transmission pulley 10 and the second transmission pulley 11 can rotate within the transmission support bearing 18, thereby ensuring the stability of the transmission. The second transmission pulley 11 can be driven by the second synchronous belt 14. The driven pulley 12 is driven to rotate. The pulley tensioning module 19 at the driven pulley 12 can ensure the tension of the second synchronous belt 14 during operation, ensuring the stable transmission of the second synchronous belt 14. When the second synchronous belt 14 rotates, it can drive the movable plate connecting plate 16 fixed on it to move. The movable plate connecting plate 16 can move on the base 1 through the pulley fixing plate 15. Through the cooperation between the movable plate connecting plate 16 and the pulley fixing plate 15, the movable plate 3 can be stably driven to move. The control board 22 can receive the signal transmitted by the signal synchronization interface, and can also receive the signal transmitted by the button 21. The power interface is provided to provide external power, which is convenient for providing power for the operation of the device.
[0037] Specifically, such as Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, a lead screw 25 is rotatably mounted inside the bearing housing 26, a lead screw nut 27 is mounted on the outside of the lead screw 25, and a lead screw nut sheet metal 28 is fixedly mounted on the outer wall of the lead screw nut 27. The end of the lead screw 25 near the drive motor 8 is fixedly connected to the first transmission pulley 10, and the lead screw nut sheet metal 28 is fixedly connected to the moving plate connecting plate 16.
[0038] By adopting the above technical solution, the technical solution of the second synchronous belt 14 belt drive in this device can also be replaced with a screw drive. In use, the drive motor 8 is powered on and can drive the motor pulley 9 to rotate. The rotation of the motor pulley 9 can drive the first transmission pulley 10 to rotate through the first synchronous belt 13. The first transmission pulley 10 is fixedly connected to the screw 25, thereby driving the screw 25 to rotate. When the screw 25 rotates, the spiral groove on the screw 25 interacts with the steel ball in the circulator groove in the screw nut 27, causing the screw to rotate. Nut 27 can move linearly along the axis of lead screw 25. Lead screw nut 27 can drive the fixedly connected lead screw nut sheet metal 28 to move linearly. Lead screw nut sheet metal 28 is fixedly connected to the moving plate connecting plate 16. In this way, the lead screw nut sheet metal 28 can drive the moving plate connecting plate 16 to move linearly. The moving plate connecting plate 16 can move on the base 1 through the pulley fixing plate 15. Through the cooperation between the moving plate connecting plate 16 and the pulley fixing plate 15, the moving plate 3 can be stably driven to move, thereby realizing the lead screw transmission to drive the moving plate 3 to move stably.
[0039] Working Principle: When installing the electric telescopic platform, the fixing plate 4 is fixed in a suitable position using bolts, etc., and the base 1 is stably supported by the fixing frame 5. When telescopic operation is performed, the transmission mechanism is energized, and the drive motor 8 is energized to drive the motor pulley 9 to rotate. The rotation of the motor pulley 9 drives the first transmission pulley 10 to rotate through the first synchronous belt 13. The first transmission pulley 10 and the second transmission pulley 11 are coaxially connected, thereby driving the second transmission pulley 11 to rotate. The transmission support bearing 18, the first transmission pulley 10, and the second transmission pulley 11 are supported by the pulley connecting plate 20. The first transmission pulley 10 and the second transmission pulley 11 can rotate within the transmission support bearing 18, thereby ensuring the stability of the transmission. The second transmission pulley 11 can drive the driven pulley 12 to rotate through the second synchronous belt 14. The pulley tensioning module 19 at the driven pulley 12 can ensure the stability of the second synchronous belt. The tension of the second synchronous belt 14 during operation ensures stable transmission. When the second synchronous belt 14 rotates, it can drive the movable plate connecting plate 16 fixed on it to move. The movable plate connecting plate 16 can move on the base 1 through the pulley fixing plate 15. The cooperation between the movable plate connecting plate 16 and the pulley fixing plate 15 can stably drive the movable plate 3 to move. The movable plate 3 can move on the base 1 through the guide wheel 7 and the guide groove 6, thereby ensuring the stability of the platform during overall telescopic movement. At the same time, the movable plate support guide wheel 24 can play a supporting and guiding role, further ensuring the stability of the movable plate 3 during movement. The limiter 23 can play a limiting role to avoid the problem of excessive extension of the electric telescopic platform. The control board 22 can receive the signal transmitted by the signal synchronization interface, and can also receive the signal transmitted by the button 21. The power interface can provide external power to facilitate the operation of the device.
