[0002] In modern life and work scenarios, smart desks, as a new type of furniture integrating multiple functions, are being used more and more widely. Whether in the office environment to accommodate different working postures, or in home life to meet the needs of people of different ages and diverse activities, smart desks are facing higher requirements for height adjustability.

[0003] However, traditional smart table lifting devices have many shortcomings. On the one hand, some lifting devices have complex structures, using too many parts and cumbersome connection methods. This not only increases manufacturing costs but also reduces the stability and reliability of the equipment, making it prone to failure during long-term use, and resulting in difficult and costly maintenance. On the other hand, some lifting devices have a single power drive method. They either rely solely on electric drive, making them unusable in emergencies such as power outages, or they rely solely on manual operation, which is laborious and makes it difficult to accurately control the lifting height, failing to meet users' needs for convenience and precision. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of traditional smart tables. On the one hand, some lifting devices have complex structures, which not only increases manufacturing costs but also makes maintenance difficult and costly. On the other hand, the lifting devices have a single power drive method, relying solely on electric drive, which makes them unusable in case of power outages or other emergencies. Furthermore, relying solely on manual operation makes the process laborious and difficult to accurately control the lifting height. Therefore, this utility model provides a lifting support device for smart tables.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A smart table lifting support device includes two sets of support plates, a lifting frame slidably connected to the support plates, a lifting component between the support plates and the lifting frame, a smart tabletop on the upper surface of the lifting frame, a connecting plate on the lower surface of the smart tabletop, a power component on the connecting plate, and a crossbar between the two sets of support plates.

[0007] Furthermore, the support plate includes a base plate, a side plate is provided on the base plate, and two sets of first fixing plates are provided on the upper surface of the base plate between the side plates.

[0008] Furthermore, a second fixing plate is provided at both the left and right ends of the lower surface of the lifting frame.

[0009] Furthermore, the lifting assembly includes a guide rod fixedly connected between two sets of first fixed plates, a lead screw rotatably connected between two sets of second fixed plates, the lead screw being a bidirectional lead screw, first movable blocks being provided on both the left and right sides of the guide rod, second movable blocks being provided on both the left and right sides of the lead screw, the second movable blocks being connected to the lead screw via ball nuts, hinge rods being provided intersecting between the two sets of first movable blocks and the two sets of second movable blocks, and a first conical tooth being provided near the middle position of the lead screw.

[0010] Furthermore, a third fixing plate is provided at both ends of the lower surface of the connecting plate, and a fourth fixing plate is provided on both sides.

[0011] Furthermore, the power assembly includes a first rotating shaft rotatably connected between the two sets of third fixed plates. The first rotating shaft has second conical teeth at both ends and a third conical tooth near the middle. A motor is provided on the outer side of one of the fourth fixed plates, and the output end of the motor has a fourth conical tooth. The third conical tooth meshes with the fourth conical tooth for transmission. The other fourth fixed plate is rotatably connected to a second rotating shaft. One end of the second rotating shaft has a fifth conical tooth. The third conical tooth meshes with the fifth conical tooth for transmission. The first conical tooth meshes with the second conical tooth for transmission.

[0012] Furthermore, a hand crank is inserted into the outer side of the second rotating shaft.

[0013] Beneficial effects: This utility model has the following beneficial effects:

[0014] 1. The lifting assembly consists of two sets of support plates slidingly connected to the lifting frame, and guide rods, lead screws and hinge rods. The structural design is simple and clear. The guide rods ensure the smooth movement of the first moving block, the two-way lead screws drive the second moving block through ball nuts, and the hinge rods realize the smooth lifting of the lifting frame. This reduces the use of complex parts, lowers the probability of failure, and enhances the stability and reliability of the equipment.

[0015] 2. The power unit integrates motor drive and manual operation. Under normal circumstances, the motor drives the lead screw to rotate through bevel gear meshing to achieve fast and precise electric lifting. In case of power failure, the user can insert the hand crank to manually rotate the second shaft, and complete the table lifting through a series of bevel gear transmissions, meeting the usage needs of different scenarios and improving the convenience and flexibility of use.

[0016] 3. In motor-driven mode, users only need to operate the motor switch to easily adjust the table height. The operation is simple and can be accurately adjusted to the appropriate height. In manual mode, the hand crank, combined with the ingenious transmission structure, is less labor-intensive than traditional manual lifting devices and can also control the lifting height more accurately, meeting users' dual needs for convenience and precision.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Combination Figures 1 to 7The intelligent table lifting support device shown includes two sets of support plates 10, a lifting frame 20 slidably connected to the support plates 10, a lifting component 30 disposed between the support plates 10 and the lifting frame 20, an intelligent tabletop 40 disposed on the upper surface of the lifting frame 20, a connecting plate 50 disposed on the lower surface of the intelligent tabletop 40, a power component 60 disposed on the connecting plate 50, and a crossbar 70 disposed between the two sets of support plates 10.

[0028] The support plate 10 includes a base plate 101, a side plate 102 is provided on the base plate 101, and two sets of first fixing plates 103 are provided on the upper surface of the base plate 101 between the side plates 102.

[0029] The lower surface of the lifting frame 20 is provided with a second fixing plate 201 at both the left and right ends.

[0030] The lifting assembly 30 includes a guide rod 301 fixedly connected between two sets of first fixed plates 103, and a lead screw 302 rotatably connected between the two sets of second fixed plates 201. The lead screw 302 is a bidirectional lead screw. First movable blocks 303 are provided on both the left and right sides of the guide rod 301, allowing them to slide flexibly on the guide rod 301, ensuring the straightness and stability of the lifting process. Second movable blocks 304 are provided on both the left and right sides of the lead screw 302, and the second movable blocks 304 are connected to the lead screw 302 via ball nuts, enabling efficient transmission of the rotational movement of the lead screw 302. The rotation of the lead screw 302 is converted into the linear motion of the second movable block 304. The two sets of first movable blocks 303 and the two sets of second movable blocks 304 are intersected by hinge rods 305. Utilizing the deformation principle of the parallelogram, the rotation of the lead screw 302 is converted into the vertical lifting motion of the lifting frame 20. This structural design makes the lifting process more stable and smooth, and can withstand a larger load. The lead screw 302 is provided with a first conical tooth 306 near the middle position, which provides an effective connection point for the power component 60 to transmit power. It can accurately transmit power to the lead screw 302 and realize precise control of the lifting function.

[0031] The lower surface of the connecting plate 50 is provided with a third fixing plate 501 at both ends and a fourth fixing plate 502 on both sides.

[0032] The power assembly 60 includes a first rotating shaft 601 rotatably connected between two sets of third fixed plates 501. The first rotating shaft 601 has second conical teeth 602 at both ends and a third conical tooth 603 near the center. A motor 604 is mounted on the outer side of one fourth fixed plate 502. The output end of the motor 604 has a fourth conical tooth 605. The third conical tooth 603 meshes with the fourth conical tooth 605 to transmit power accurately from the motor 604 to the first rotating shaft 601. The other fourth fixed plate 502... The plate 502 is rotatably connected to the second rotating shaft 606. One end of the second rotating shaft 606 is provided with a fifth conical tooth 607. The third conical tooth 603 meshes with the fifth conical tooth 607 for transmission, and the first conical tooth 306 meshes with the second conical tooth 602 for transmission. The rotational power of the first rotating shaft 601 is transmitted to the lead screw 302, thereby driving the lead screw 302 to rotate and realizing the lifting movement of the lifting frame 20. The entire power transmission process is realized through the meshing of multiple conical teeth, which has the advantages of high transmission efficiency, large torque and low noise.

[0033] A hand crank 608 is inserted into the outer side of the second rotating shaft 606, providing manual operation functionality. This increases the device's flexibility and emergency response capabilities. When the motor 604 malfunctions or experiences a power outage, the user can manually rotate the hand crank 608 to drive the second rotating shaft 606. This, in turn, drives the lead screw 302 through the transmission of the fifth conical gear 607, the third conical gear 603, the second conical gear 602, and the first conical gear 306, thereby raising and lowering the intelligent tabletop 40. This manual operation provides a backup plan for the user, ensuring that the intelligent table can still be used normally under special circumstances, thus improving the device's practicality and reliability.
