Description
Technical Field
[0001] This utility model belongs to the field of multimedia device technology, specifically relating to an ultra-thin embedded multimedia lifting device. Background Technology
[0002] In the intelligent upgrade of conference rooms, classrooms, exhibition halls, and other scenarios, embedded multimedia lifting devices are widely used due to their space-saving and environmentally friendly features. However, existing embedded multimedia lifting devices still have significant shortcomings in terms of fixing and adapting display devices. Currently, the fixing of display devices in embedded structures mostly adopts preset clips or manual locking methods. During installation, the display device must first be inserted into the preset slot, and then the bolts are tightened or the clips are engaged manually to complete the fixing. The operation steps are cumbersome, especially when the embedded installation space is limited, as manual operation is restricted, resulting in low fixing efficiency. Moreover, manual fixing makes it difficult to ensure uniform clamping force on both sides, and the display device is prone to lateral displacement after being inserted, affecting the regularity of the embedded installation. In fact, during the lifting process, the shaking can increase friction with the slot wall, causing wear and tear on the device.
[0003] Meanwhile, the existing embedded devices have poor adaptability in their fixing structure. For display devices of different thicknesses, it is necessary to replace the embedded fixture with one of the corresponding size or modify the slot, resulting in insufficient versatility and increased usage costs and maintenance difficulty. Based on the above problems, this application proposes an ultra-thin embedded multimedia lifting device to improve these issues. Utility Model Content
[0004] The purpose of this invention is to provide an ultra-thin embedded multimedia lifting device that can trigger an automatic clamping mechanism by the weight of the display device itself. The device uses a gear and rack meshing transmission to achieve synchronous closing of the two fixing components, eliminating the need for manual operation and providing convenient and stable fixing. At the same time, it uses a tension spring to achieve automatic reset, improving efficiency.

[0018] Please see the appendix Figures 1 to 3 As shown, this utility model provides an ultra-thin embedded multimedia lifting device, including a base plate 10. A lifting assembly 11 is mounted on the upper end of the base plate 10. A support plate 20 is provided at one end of the lifting assembly 11. A first groove 21 is formed inside the support plate 20. A rotating rod 22 is rotatably connected inside the first groove 21. A gear 23 is fixedly connected to the outer side of the rotating rod 22. A movable plate 24 is slidably connected inside the first groove 21. Multiple teeth are provided on the inner wall of the movable plate 24 near the gear 23. The multiple teeth are arranged vertically, and the gear 23 meshes with the multiple teeth. A second groove 25 is formed inside the support plate 20, and the second groove 25 communicates with the first groove 21. Racks 26 are provided at both the upper and lower ends of the gear 23. Two racks 26 are located on one side of the movable plate 24 and... The gear 23 and rack 26 are meshed and connected inside the second slide groove 25. The ends of the two racks 26 that are far apart from each other are fixed with slide plates 27. The ends of the two slide plates 27 that are far apart from each other are equipped with fixing components 35. The first slide groove 21 is fixed with a fixing rod 28. The outside of the fixing rod 28 is fixed with a tension spring 29. The second connecting plate 30 is fixed inside the movable plate 24 and below the tension spring 29. The end of the tension spring 29 that is far away from the fixing rod 28 is fixedly connected to the second connecting plate 30. The lower end of the movable plate 24 extends to the lower end of the support plate 20. The lower end of the movable plate 24 is fixed with a load-bearing plate 31. The end of the support plate 20 that is far away from the lifting component 11 has an embedding groove 32. The support plate 20 is fixed inside the support plate 20 and on one side of the embedding groove 32 with a limiting plate 33. The limiting plate 33 is made of transparent material.
[0019] In this embodiment, in the initial state, the tension spring 29 can keep the movable plate 24 (the movable plate 24 is I-shaped) and the load-bearing plate 31 in a balanced state. During installation, the multimedia display device is placed in the embedding groove 32, and the limiting plate 33 (transparent material) can limit one side of the display device to prevent it from shifting laterally. When the weight of the display device itself acts on the load-bearing plate 31, the load-bearing plate 31 drives the movable plate 24 to slide downward along the first sliding groove 21. The teeth on the inner wall of the movable plate 24 (the teeth are set on the movable plate 24 and located at the right end outside the gear 23) mesh with the gear 23. The gear 23 on the rotating rod 22 rotates clockwise. As the gear 23 rotates clockwise, it is connected to racks 26 at both ends, causing the racks 26 to move along the second slide groove 25 towards each other. Slide plates 27 are fixed to the ends of the racks 26 that are furthest apart. These slide plates 27 then move the two fixing components 35 synchronously towards each other. This synchronous movement of the fixing components 35 allows them to automatically clamp and fix themselves from both sides of the display device, ensuring stable placement. When the display device needs to be replaced or repaired, the load-bearing plate 31 is moved upwards, causing the display device to move upwards. After the display device is removed, the spring force generated by the tension spring 29 resets the moving plate 24. Then, through the meshing of the gear 23 and racks 26, the fixing components 35 return to their initial position for future use. Furthermore, the lifting assembly 11 can drive the support plate 20 and the display device above it to achieve height adjustment, flexibly adapting to the height requirements of different usage scenarios. The overall structure achieves automatic fixing and resetting of the display device through mechanical linkage, which is convenient to operate and securely fixed. The transparent limiting plate 33 can limit the position without affecting the display effect, improving the practicality and reliability of the device. It should be noted that the sides of both clamping plates 36 are provided with rubber material. When the sliding plate 27 moves the clamping plates 36 towards the display device, the rubber of the clamping plates 36 in contact with the side of the display device first adheres to the display device. The rubber can prevent the clamping plates 36 from hard contact with the display device and cause scratch damage, while increasing the friction of the contact surface.
[0020] Secondly, please refer to it again. Figures 2 to 4 The fixing component 35 includes a clamping plate 36, a clamping plate 37, a sliding rod 38, a spring 39, a threaded rod 40, and a knob 41. The clamping plate 36 is fixed to one end of the sliding plate 27. The clamping plate 37 is slidably connected to the inside of the clamping plate 36. The sliding rod 38 is slidably connected to the inside of the clamping plate 36, and one side of the sliding rod 38 is fixedly connected to the clamping plate 37. A baffle is fixed to the side of the sliding rod 38 away from the clamping plate 37. A spring 39 is provided inside the clamping plate 36 and outside the sliding rod 38. The threaded rod 40 is threadedly connected to the inside of the clamping plate 36. The knob 41 is fixed to the side of the threaded rod 40 away from the clamping plate 37.
[0021] In this embodiment, when the fixing component 35 is working, in the initial state, under the action of the spring 39, the slide rod 38 and the clamping plate 37 move towards one end of the knob 41. At this time, the clamping plate 37 is located inside the clamping plate 36. If it is necessary to reinforce or adapt to display devices of different thicknesses, the knob 41 can be rotated to drive the threaded rod 40 to rotate threadedly inside the clamping plate 36. One end of the threaded rod 40 pushes against the clamping plate 37, adjusting the contact pressure between the clamping plate 37 and the display device to achieve precise clamping. The baffle on one side of the slide rod 38 and located inside the clamping plate 36 can prevent the slide rod 38 from falling out of the clamping plate 36, ensuring structural stability. It adapts to display devices of different specifications and avoids over-clamping and damage to the equipment, improving the adaptability and protection of the fixing component 35.
[0022] Secondly, please refer to the following as well. Figure 1 and Figure 5 The lifting assembly 11 includes a housing 12, an electric push rod 13, a support rod 14, and a first connecting plate 15. The housing 12 is fixed to the upper end of the base plate 10. The electric push rod 13 is assembled to the upper end of the base plate 10 and located inside the housing 12. The support rod 14 is fixed to the output end of the electric push rod 13. The first connecting plate 15 is fixed to one side of the upper end of the support rod 14, and the first connecting plate 15 and the support plate 20 are fixedly connected.
[0023] In this embodiment, when the lifting assembly 11 is working, the electric push rod 13 can be activated by operating the switch 16 on the upper housing 12 of the base plate 10, and the support rod 14 at the output end of the electric push rod 13 will then extend and retract. Since the first connecting plate 15 fixes the support rod 14 to the support plate 20, the extension and retraction of the support rod 14 will drive the support plate 20 and the display device above it to rise and fall synchronously, thereby realizing flexible adjustment of the height of the display device to meet the viewing or operation needs in different usage scenarios. The housing 12 not only protects the internal components such as the electric push rod 13 and the support rod 14 from dust and impurities affecting the operation of the equipment, but also makes the overall structure of the lifting assembly 11 more regular and improves the aesthetics of the device.
[0024] To further understand and explain, Figure 1 and Figure 5 For example, a switch 16 is provided at the upper end of the outer casing 12, and the electric push rod 13 is electrically connected to an external power supply through a wire.
[0025] In this embodiment, when the height of the display device needs to be adjusted, the operator only needs to press the switch 16 to trigger the circuit to open and close, and control the start, stop and extension / retraction direction of the electric push rod 13: when the up button is pressed, the electric push rod 13 is energized and drives the support rod 14 to extend, thereby raising the support plate 20 and the display device; when the down button is pressed, the electric push rod 13 rotates in the opposite direction, the support rod 14 retracts, and the display device is lowered; when the switch 16 is released, the electric push rod 13 stops immediately, so that the display device stays at the current height.
[0026] It should be noted that a controller is installed inside the housing 12. When the lifting assembly 11 is working, by operating the switch 16 on the upper end of the housing 12 of the base plate 10, the switch 16 converts the user's lifting command into an electrical signal and transmits it to the controller inside the housing 12. The signal can be quickly analyzed and processed. The controller presets the operating parameters of the electric push rod 13 (such as lifting speed, travel limit, etc.). The analyzed signal will trigger the controller to send precise drive commands to the electric push rod 13, thereby controlling the electric push rod 13 to start, stop, or switch the extension and retraction direction according to the command.
[0027] In a preferred embodiment, please refer to Figure 1 Rollers 17 are provided at the four corners of the bottom of the base plate 10.
[0028] In this embodiment, when the entire ultra-thin embedded multimedia lifting device needs to be moved, the operator only needs to push the main body of the device, and the rollers 17 at the lower end of the base plate 10 will roll accordingly, making it easier and more convenient to adjust the position of the device in scenarios such as conference rooms and classrooms. At the same time, the rollers 17 are usually equipped with a braking structure. When the device moves to the target position, the rollers 17 can be locked to prevent the device from shifting due to accidental collisions during use, thus balancing mobility and stability.
[0029] The working principle of this utility model is as follows: In the initial state, the tension spring 29 pulls the moving plate 24 through the second connecting plate 30, keeping the moving plate 24 balanced with the load-bearing plate 31. The fixing component 35 is in the open state, and the clamping plate 37 of the fixing component 35 retracts into the clamping plate 36 under the action of the spring 39. The roller 17 at the lower end of the base plate 10 is in a rolling state to facilitate the movement of the device. When installing the display device, it is placed into the embedding groove 32 of the support plate 20. The transparent limiting plate 33 limits one side of the display device to prevent lateral displacement. The weight of the device acts on the load-bearing plate 31 and drives the moving plate 24 to slide downwards along the first slide groove 21. The teeth on the inner wall of the moving plate 24 mesh with the gear 23 on the outer side of the rotating rod 22, driving the gear 23 to rotate clockwise. The gear 23 then meshes with the racks 26 at the upper and lower ends, driving the two racks 26 to move closer to each other along the second slide groove 25. The sliding plate 27 pushes the two fixed components 35 to move closer together synchronously. The rubber material on the side of the clamping plate 36 fits against the display device to achieve automatic clamping on both sides. If reinforcement or adaptation to different thicknesses is required, [further details can be added]. The display device rotates by turning knob 41, causing threaded rod 40 to rotate within clamping plate 36. This pushes clamping plate 37 and adjusts clamping pressure via guide rod 38. A baffle on one side of the guide rod 38 prevents it from falling out of clamping plate 36, ensuring structural stability. To adjust the height, press switch 16 on housing 12. Switch 16 converts the command into an electrical signal and transmits it to controller inside housing 12. After analysis, controller sends a drive command to electric push rod 13. Electric push rod 13 drives support rod 14 to extend and retract, which in turn drives support plate 20 and display device to rise and fall via first connecting plate 15. Releasing switch 16 stops the device at the target height. To move the device, push the main body to make roller 17 roll. After reaching the target position, lock the braking structure of roller 17 to prevent displacement. To repair or replace the display device, lift the load-bearing plate 31 to move the display device upwards and remove it. The rebound force of tension spring 29 pulls moving plate 24 to reset. The meshing transmission of gear 23 and rack 26 returns the fixing component 35 to its initial open position for easy use next time.
[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
