[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This application provides an electronic nameplate lifting structure, solving the problem that fixed-installation electronic nameplates cannot achieve lifting functionality. In scenarios requiring frequent nameplate changes or meeting layout adjustments, operation is inconvenient. Furthermore, some lifting nameplates are prone to malfunction during lifting, and the lack of effective lubrication for transmission components leads to high friction, increasing the load on the drive components, accelerating wear, and shortening the lifespan of the nameplates.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] Example 1: This utility model embodiment discloses an electronic table card lifting structure, according to the attached... Figure 1-5 As shown, it includes a base 1, a lifting unit 3, and a lubrication unit 4;

[0034] The base 1 supports the main body 2 of the electronic nameplate. The base 1 is the foundation for the entire electronic nameplate lifting structure, and its internal cavity structure provides installation space for the main body 2 and the lifting unit 3. The main body 2 of the electronic nameplate is the main display part of the lifting structure, used to display relevant information such as the names and seat numbers of people at the conference table. The lifting unit 3 allows for raising and lowering, enabling it to be raised for display when needed and stored back into the base 1 when not in use.

[0035] The lifting unit 3 is located inside the base 1 and is used to drive the electronic table card body 2 to move. The lifting unit 3 includes a slide 31, a motor 32, a lead screw 33 and a guide rod 34.

[0036] The slide block 31 is slidably connected within the base 1 and serves to support the electronic table sign body 2. The slide block 31 is threadedly connected to the lead screw 33, and the rotation of the lead screw 33 enables the slide block 31 to move up and down, thereby driving the electronic table sign body 2 to rise and fall. In addition, the slide block 31 is also slidably connected to the guide rod 34, which is fixedly connected inside the base 1 and guides the movement of the slide block 31, ensuring the stability and accuracy of the movement of the slide block 31.

[0037] The motor 32 is installed inside the base 1; the motor 32 serves as the power source for the lifting unit 3 and is fixedly installed inside the base 1. Its output end is connected to the lead screw 33, and the motor 32 drives the lead screw 33 to rotate by rotating in both directions, thereby realizing the raising and lowering of the slide 31.

[0038] The lead screw 33 is located at the output end of the motor 32 and is threadedly connected to the slide 31. When the motor 32 drives the lead screw 33 to rotate, the threaded transmission between the lead screw 33 and the slide 31 causes the slide 31 to move linearly, thereby driving the electronic table card body 2 to rise and fall.

[0039] The lubrication unit 4 is mounted on the slide block 31 and is used to lubricate the transmission part of the lead screw 33.

[0040] A guide rod 34 is fixedly connected inside the base 1, and the slide 31 is slidably connected to the guide rod 34. The guide rod 34 provides precise linear motion guidance for the slide 31, prevents the slide 31 from rotating with the lead screw 33, bears lateral force, and ensures that the electronic table card body 2 rises and falls smoothly without shaking.

[0041] A limiting frame 21 is fixedly connected between the electronic table sign body 2 and the slide 31, and the limiting frame 21 is slidably connected inside the base 1. When the slide 31 drives the electronic table sign body 2 to rise and fall, the sliding connection of the limiting frame 21 inside the base 1 provides additional guidance and support points, further constraining the movement trajectory of the electronic table sign body 2, enhancing its rigidity and stability, and preventing it from swaying back and forth or left and right.

[0042] Lubrication unit 4 includes:

[0043] A lubrication box 41 is mounted on the slide 31; the lubrication box 41 is used to store lubricating grease. Its position moves with the slide 31 and is always close to the thread engagement area of ​​the lead screw 33 that requires lubrication.

[0044] A rubber wheel 42 is rotatably connected within the lubrication tank 41 and contacts the lead screw 33. When the lead screw 33 rotates, friction drives the rubber wheel 42 to rotate synchronously. The rubber wheel 42 is immersed in grease within the lubrication tank 41. As the rubber wheel 42 rotates, the grease adsorbed on its surface is carried to the contact area with the lead screw 33 and, under contact pressure, is applied to the threaded surface of the lead screw 33. This achieves automatic, continuous, and uniform lubrication. The lubrication components are driven by the movement of the lead screw 33 itself, requiring no additional power. The rubber material has a certain degree of elasticity, allowing it to conform well to the irregular threaded surface of the lead screw 33, ensuring effective grease transfer. This significantly extends the maintenance-free cycle of the lead screw 33 assembly, reduces wear, and lowers operating noise.

[0045] Grease guide hole 43 is provided at the connection between lubrication tank 41 and rubber wheel 42. Grease guide hole 43 allows grease in lubrication tank 41 to flow to the surface of rubber wheel 42 or directly seep into the contact area under the action of gravity or the micro-motion generated by the rotation of rubber wheel 42, ensuring a continuous supply of grease.

[0046] The lubrication tank 41 is equipped with a filling nozzle 411, and a cap 412 is threaded onto the filling nozzle 411. The filling nozzle 411 and the cap 412 facilitate the addition and sealing of grease.

[0047] A sealing ring 413 is movably engaged between the cap 412 and the filling nozzle 411. The sealing ring 413 ensures a tight connection between the cap 412 and the filling nozzle 411.

[0048] A maintenance backplate 5 is movably attached to the back of the base 1, and the maintenance backplate 5 has heat dissipation holes 51. The maintenance backplate 5 is fixed to the maintenance port on the back of the base 1 by clips or screws, sealing the rear of the base 1, and can be easily disassembled when maintenance or maintenance of internal components is required. The heat dissipation holes 51 promote air circulation inside the base 1, helping to dissipate the heat generated by the generator 32. Therefore, the maintenance backplate 5 greatly facilitates the installation, commissioning, and maintenance of the equipment, reducing later maintenance costs. The heat dissipation holes 51 effectively improve internal heat dissipation conditions, prevent the motor 32 from overheating, and improve the reliability and service life of the system.

[0049] The operating steps for using this electronic table card lifting mechanism are as follows:

[0050] Installation: Install the base 1 in a suitable position, then fix the main body 2 of the electronic table card to the slide 31 through the limit bracket 21, and ensure that each component is installed correctly and connected firmly.

[0051] Grease filling: Open the cap 412, add an appropriate amount of grease into the lubrication box 41 through the filling nozzle 411, and then tighten the cap 412 to ensure that the sealing ring 413 is installed in place.

[0052] Usage: The electronic table sign body 2 is raised and lowered by controlling the forward and reverse rotation of the motor 32. When it is necessary to raise the electronic table sign body 2, the motor 32 rotates forward, driving the lead screw 33 to rotate, and the slide 31 slides upward along the guide rod 34, thereby raising the electronic table sign body 2; when it is necessary to lower the electronic table sign body 2, the motor 32 rotates in reverse, driving the lead screw 33 to rotate in the opposite direction, and the slide 31 slides downward along the guide rod 34, thereby lowering the electronic table sign body 2.

[0053] Maintenance: When the equipment malfunctions or requires maintenance, disassemble the inspection backplate 5 to inspect and repair the components inside the base 1. After maintenance, reinstall the inspection backplate 5.
