[0026] Embodiment:

[0027] Please refer to Figures 1-5 , an electric table that can be assembled and disassembled, including a base 1, a tabletop plate 2 and a driving motor 3. The tabletop plate 2 is composed of multiple groups and is in a disc shape above the base 1. The driving motor 3 is fixed on the base 1. The output shaft of the driving motor 3 is fixedly connected with a threaded rod 4. The surface of the threaded rod 4 is sleeved with a first sleeve 5. The first sleeve 5 is located at the center of multiple tabletop plates 2. The upper surface of the first sleeve 5 is inserted with a mounting plate 6. The mounting plate 6 is threadedly connected to the top end of the threaded rod 4. The surface of the first sleeve 5 is provided with a mounting groove 7. A mounting block 9 hinged to the tabletop plate 2 slides in the mounting groove 7. A positioning component is arranged in the mounting groove 7.

[0028] The working principle of the above technical solution is as follows:

[0029] By starting the drive motor 3, the rotation of its output shaft drives the fixedly connected threaded rod 4 to rotate. Since the threaded rod 4 is threadedly connected to the first sleeve 5, the rotation of the threaded rod 4 causes the first sleeve 5 to move axially along the threaded rod 4. When the first sleeve 5 moves upward, the mounting block 9 in the mounting groove 7 moves accordingly. Because the mounting block 9 is hingedly connected to the tabletop plate 2, it drives the tabletop plate 2 to gradually unfold. The positioning component in the mounting groove 7 works. When the mounting block 9 moves to a suitable position, the positioning component fixes it to ensure the stable unfolding of the tabletop plate 2.

[0030] Please refer to Figure 1 and Figure 4 As shown in Figure 4 , the threaded rod 4 is threadedly connected to a second moving plate 13 located below the first sleeve 5. The surface of the second moving plate 13 is symmetrically inserted with positioning rods 14 fixedly connected to the base 1. The surface of the second moving plate 13 is hingedly connected to a support rod 15, and one end of the support rod 15 away from the second moving plate 13 is hingedly connected to a slider 16.

[0031] When the threaded rod 4 rotates, the second moving plate 13 threadedly connected to the threaded rod 4 will move up and down along the threaded rod 4. Since the surface of the second moving plate 13 is symmetrically inserted with positioning rods 14 fixedly connected to the base 1, the positioning rods 14 can limit the rotation of the second moving plate 13, enabling it to move only along the axial direction of the threaded rod 4. When the second moving plate 13 moves, the support rod 15 hingedly connected to its surface will move accordingly. The slider 16 hingedly connected to one end of the support rod 15 away from the second moving plate 13 will slide in the corresponding structure, thus providing support and assistance for the unfolding or folding of the entire electric table.

[0032] Please refer to Figure 5 As shown in Figure 5 , the positioning component includes a proximity sensor 8, a cylinder 10, and a first moving plate 11. The proximity sensor 8 is fixed in the mounting groove 7. The cylinders 10 are symmetrically fixed on the lower surface of the first sleeve 5. The first moving plate 11 is located in the mounting groove 7 and fixed to the output end of the cylinder 10. A plug board 12 inserted into the mounting block 9 is fixed on the lower surface of the first moving plate 11.

[0033] During the unfolding process of the tabletop plate 2, the proximity sensor 8 fixed in the mounting groove 7 monitors the position of the mounting block 9 in real time. When the mounting block 9 moves to a predetermined position, the proximity sensor 8 sends a signal to the cylinders 10 symmetrically fixed on the lower surface of the first sleeve 5. After receiving the signal, the cylinders 10 are activated to push the first moving plate 11 located in the mounting groove 7 and fixed to the output end of the cylinder 10 to move. The plug board 12 fixed on the lower surface of the first moving plate 11 is inserted into the mounting block 9 accordingly, thereby realizing the fixation of the mounting block 9 and ensuring the stable state of the tabletop plate 2 after unfolding.

[0034] Please refer to Figure 3 and Figure 5, the number of the proximity sensors 8 is four and they are distributed in a circumferential array.

[0035] Since the number of the proximity sensors 8 is four and they are distributed in a circumferential array within the mounting groove 7, the position change of the mounting block 9 can be comprehensively monitored from multiple directions and angles. During the unfolding process of the tabletop plate 2, no matter from which direction the mounting block 9 approaches the predetermined position, it can be detected by at least one proximity sensor 8 in a timely manner, thus ensuring the comprehensiveness and accuracy of the detection and providing timely and accurate signals for the subsequent positioning and fixing operations.

[0036] Please refer to Figure 2 and Figure 4 , the number of the support rods 15 is six, and the support rods 15 are in a circular inverted cone shape radiating outward with the first sleeve 5 as the core.

[0037] When the electric table is unfolded or folded up, the six support rods 15 move along with the up and down movement of the second moving plate 13. Since they are in a circular inverted cone shape radiating outward with the first sleeve 5 as the core, they can evenly share the pressure from the tabletop plate 2 and provide stable supporting force during the movement. This shape and distribution method enable the support rods 15 to effectively adapt to the movement track of the tabletop plate 2 and ensure the smooth unfolding or folding up of the tabletop plate 2.

[0038] Please refer to Figure 4 , a sliding groove 17 is formed on the lower surface of the tabletop plate 2, and the slider 16 is slidably connected to the sliding groove 17.

[0039] During the unfolding or folding up process of the electric table, along with the movement of the support rods 15, the slider 16 hinged to the end thereof slides within the sliding groove 17 formed on the lower surface of the tabletop plate 2. When the tabletop plate 2 is unfolded, the slider 16 slides forward within the sliding groove 17, and when the tabletop plate 2 is folded up, the slider 16 slides backward within the sliding groove 17. This sliding connection method enables the slider 16 to smoothly move along with the movement of the tabletop plate 2, thus providing guidance and support for the movement of the tabletop plate 2.

[0040] Please refer to Figure 5 , the proximity sensors 8 are in a fitting state with the surface of the mounting block 9.

[0041] Since the proximity sensors 8 are in a fitting state with the surface of the mounting block 9, when the mounting block 9 moves, its position change can be perceived more directly and accurately. This fitting state reduces the induction error and delay, enabling the proximity sensors 8 to quickly and accurately obtain the position information of the mounting block 9 and make corresponding responses in a timely manner.

[0042] During operation, when the drive motor 3 starts, its output shaft begins to rotate and drives the threaded rod 4 fixedly connected thereto to rotate. Since the threaded rod 4 is threadedly connected to the first sleeve 5, the rotation of the threaded rod 4 causes the first sleeve 5 to move up and down along the axial direction of the threaded rod 4. When the first sleeve 5 moves upward, the mounting block 9 in the mounting groove 7 will move along the movement track of the first sleeve 5. Since the mounting block 9 is hingedly connected to the tabletop plate 2, the movement of the mounting block 9 will drive the tabletop plate 2 to gradually unfold;

[0043] During the process of the tabletop plate 2 unfolding, the four proximity sensors 8 arranged in a circular array in the mounting groove 7 will detect the position of the mounting block 9 in real time. And since the number of proximity sensors 8 is four, it can avoid the damage of a single proximity sensor 8 during use, which may affect the overall unfolding and contraction. When the mounting block 9 moves to a preset appropriate position, the proximity sensors 8 will send signals to the cylinders 10 symmetrically fixed on the lower surface of the first sleeve 5. After receiving the signals, the cylinders 10 are activated to push the 11 fixed to the output end of the cylinder 10 in the mounting groove 7. The insertion plate 12 fixed to the lower surface of the 11 will then be inserted into the mounting block 9, effectively positioning and fixing the mounting block 9, thereby ensuring that the tabletop plate 2 can be stably maintained in the unfolded state. At the same time, when the threaded rod 4 rotates, the second moving plate 13 that is threadedly connected to the threaded rod 4 and located below the first sleeve 5 will also move up and down along the threaded rod 4. The positioning rods 14 fixedly connected to the base 1 are symmetrically inserted on the surface of the second moving plate 13. These positioning rods 14 can ensure the stability and accuracy of the movement of the second moving plate 13. The movement of the second moving plate 13 will drive the six support rods 15 hingedly connected to its surface. These support rods 15 are in the shape of a circular inverted cone radiating outward with the first sleeve 5 as the core. The sliders 16 hinged to the ends of the support rods 15 away from the second moving plate 13 will slide in the sliding grooves 17 opened on the lower surface of the tabletop plate 2. Such a design provides additional support and stability for the unfolding process of the tabletop plate 2, making the tabletop plate 2 more stable and reliable during unfolding and use;

[0044] At the same time, when disassembly, maintenance or transportation is required, first, the cylinders 10 contract, driving the 11 and the insertion plate 12 to be withdrawn from the mounting block 9, releasing the fixation of the mounting block 9. Then, the drive motor 3 rotates in reverse, causing the threaded rod 4 to rotate in the reverse direction, the first sleeve 5 to move downward, the mounting block 9 to move accordingly, driving the tabletop plate 2 to fold up. At the same time, the second moving plate 13 also moves upward, and the support rods 15 drive the sliders 16 to slide in the sliding grooves 17 to assist the tabletop plate 2 in folding up. After folding up is completed, the first sleeve 5 and the second moving plate 13 can be rotated on the surface of the threaded rod 4 by hand. At this time, the first sleeve 5 and the second moving plate 13 can be removed from the surface of the threaded rod 4 to complete the disassembly operation. Finally, each component can be disassembled in sequence to achieve the disassembly of the electric table, which is convenient for transportation and storage.

[0045] The above-described embodiments merely represent the specific implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
