The panel 1 is provided with a bent portion 102 on one side where the controller 6 is installed. The controller 6 includes a display screen 601 and a plurality of buttons 602. The controller 6 is connected to an electric control element 11. A power connector 1101 is arranged at one end of the electric control element 11.

[0028] Panel 1 is the loading platform of the lifting table. The area of ​​panel 1 is large enough and the surface is flat, so it can accommodate the items needed for office and study. It is usually made of wood to ensure load-bearing capacity and durability. The first support leg 2 and the second support leg 3 are the supporting structure of the table. They are fixed to the lower part of the table to provide stable support. The support leg is made of metal material and has sufficient strength and stability to stably support the panel 1 and the items placed on it. The synchronization shaft 7 is a component connecting the first support leg 2 and the second support leg 3. They ensure that the two support legs are lifted and lowered at the same time to maintain the balance of the panel 1. The drive motor 5 is a key component for realizing the lifting function. It drives the rotation of the synchronization shaft 7 by electric means, thereby realizing the lifting and lowering of the panel 1. The drive motor can be a DC motor or a stepper motor to adapt to different application scenarios and expand the product coverage. The controller 6 is an electronic device connected to the drive motor 5, which is convenient for users to use the lifting and lowering of the control panel 1. The controller 6 includes a display screen 601 and a plurality of buttons 602 for setting and adjusting the height of the table. The controller 6 is also connected to the electric control element 11, and the power connector 1101 allows the user to conveniently connect an external power cord. Two wire holes 101 are provided on the panel 1, through which the device wires and transmission data cables placed on the panel 1 can be guided to the bottom surface of the panel 1 to enhance the appearance. A bend 102 is provided on one side of the panel 1, and the design of the bend 102 enhances the texture of the panel 1 and meets the requirements of modern aesthetics and ergonomics.

[0029] The first supporting leg 2 and the second supporting leg 3 have the same structure, and are respectively connected to the first pad 201 and the second pad 301 at the bottom, and the inner cylinder slides and nests the first lifting frame 8 and the second lifting frame 9, and the top of the first lifting frame 8 and the second lifting frame 9 are respectively installed with a lifting drive mechanism 13, which is connected to the synchronous shaft 7, and two leveling feet 4 are respectively arranged at the bottom of the first pad 201 and the second pad 301.

[0030] The lifting drive mechanism 13 includes a screw rod 1302, an inverted nut 1303, a first plastic bearing 1304, and a second plastic bearing 1305. The inverted nut 1303 is fixedly connected to the first lifting frame 8 or the second lifting frame 9. The inverted nut 1303 passes through the screw rod 1302, and the screw rod 1302 is perpendicular to the first supporting leg 2 and the second supporting leg 3. A long shaft gear 1306 is arranged between the first plastic bearing 1304 and the second plastic bearing 1305. The long shaft gear 1306 is meshed with the lifting gear 1307 at the top of the inverted nut 1303. The synchronous shaft 7 is matched with the first plastic bearing 1304 and the second plastic bearing 1305 through a hexagonal screw hole. A shell 1301 is arranged on the top of the two lifting drive mechanisms 13 to wrap the internal gear set. The shell 1301 is fixedly connected to the first lifting frame 8 and the second lifting frame 9. A third bearing 1308 is arranged below the lifting gear 1307. The power of the driving motor 5 is transmitted to the lifting driving mechanism 13 at both ends through the synchronous shaft 7, further driving the long shaft gear 1306 to rotate, and finally the lifting gear 1307 drives the screw rod 1302 to rotate. Since the inverted nut 1303 is fixedly connected to the first lifting frame 8 and the second lifting frame 9, when the screw rod 1302 rotates, due to the torque, the inverted nut 1303 can move up and down with the forward and reverse rotation of the driving motor 5, thereby causing the first lifting frame 8, the second lifting frame 9 to move relative to the first supporting foot 2, the second supporting foot 3, thereby achieving the effect of lifting and lowering the panel 1.

[0031] The first pad 201 and the second pad 301 provide additional stability and support area for the lifting table as a whole to ensure that the table remains balanced and stable during lifting and daily use to avoid shaking.

[0032] The first lifting frame 8 and the second lifting frame 9 are designed to lift the first lifting frame 8 and the second lifting frame 9 through the rotation of the synchronization shaft 7, so as to realize the lifting and lowering of the panel 1. The lifting frame is made of metal material and has sufficient strength and durability to bear the weight of the desktop and provide stable movement.

[0033] The leveling foot 4 is a component for adjusting the horizontal balance of the table. The leveling foot 4 at the bottom of each support foot can be adjusted independently to adapt to the unevenness of the ground, ensuring that the tabletop can remain horizontal and stable on any ground.

[0034] The first lifting frame 8 has the same structure as the second lifting frame 9. The first lifting frame 8 includes a vertical rod 801, a horizontal rod 802, and a first connecting member 803. The vertical rod 801 is slidably nested in the first supporting foot 2. The horizontal rod 802 is located at the top of the vertical rod 801 and is perpendicular to the vertical rod 801. The first connecting member 803 is located at the connection between the vertical rod 801 and the horizontal rod 802. The first connecting member 803 remains perpendicular to the vertical rod 801 and the horizontal rod 802 at the same time.

[0035] A connecting rod 10 is arranged between the first lifting frame 8 and the second lifting frame 9, and the connecting rod 10 includes a first square tube 1001 and a second square tube 1002. One end of the first square tube 1001 is connected to the first connecting piece 803, and the end of the second square tube 1002 away from the first connecting piece 803 is connected to the connecting piece of the second lifting frame 9. A cross plate 1003 is arranged in the middle of the connecting rod 10. The cross plate 1003 is parallel to the cross bar 802 and the cross bar of the second lifting frame 9. The second connecting piece 1004 and the third connecting piece 1005 are respectively arranged on both sides of the cross plate 1003.

[0036] A guide ring 12 is provided between the first lifting frame 8 and the first supporting leg 2 . The guide ring 12 includes a transition outer edge 1201 and a buckle 1202 . The transition outer edge 1201 surrounds the first lifting frame 8 , and the buckle 1202 is matched with the first supporting leg 2 .

[0037] The vertical rod 801, the crossbar 802, and the first connecting member 803 are all made of high-strength metal materials, such as aluminum alloy, to provide sufficient structural strength and stability while reducing the overall weight. The connecting rod 10 connects the first lifting frame 8 and the second lifting frame 9 so that they can move in coordination. The surface of the first square tube 1001 and the second square tube 1002 is flat, providing more bearing surfaces to support the panel 1. The second connecting member 1004 and the third connecting member 1005 are tightened with the panel 1 by screws to enhance the tightness of the connection between the panel 1 and the connecting rod 10. The guide ring 12 is located between the lifting frame and the support foot, and plays a role in guiding and stabilizing the movement of the lifting frame. The transition outer edge 1201 surrounds the lifting frame, so that the lifting frame is closely connected to the support foot, eliminating the gap, and providing additional support and guidance for the lifting frame. The buckle 1202 is connected to the support foot so that the buckle and the support foot can be quickly assembled and installed.

[0038] The specific working method of the utility model is as follows: Figure 1 , Figure 2After the installation is completed, the lifting table is leveled as a whole by the leveling foot 4 to avoid shaking. The electric control element 11 is connected to the power supply, and the controller 6 is turned on. The display screen 601 intuitively displays the height difference between the current panel 1 and the pad. The button 602 includes the functions of rising, falling, three sets of preset heights, and reset. Long press the rising and falling buttons to control the drive motor 5 to drive the synchronous shaft 7 to rotate the gear of the lifting drive mechanism 13. The screw rod 1302 is used to start the upside-down nut 1303 to move up and down, so that the first lifting frame 8, the second lifting frame 9 and the first support foot 2, the second support foot 3 have a height difference, thereby realizing the height control of the panel 1. Release the rising and falling buttons to stop. The current height can be stored by long pressing the preset height button. Click the preset height button, and the electric control element 11 will judge the difference between the current height and the preset value, so as to adjust the panel 1 from the current height to the preset height. Click the reset function, and the effect of restoring the panel 1 to the lowest height with one key can be displayed. The overall design of the lifting table is simple and practical, easy to transport and assemble, with good functional effects, and suitable for different office and entertainment needs.
