[0022] This utility model provides an adjustable height table, such as Figures 1 to 7 As shown, the adjustable height desk includes: The support assembly 1 includes a height-adjustable table leg 11 and a support frame 12. The height-adjustable table leg 11 includes an inner leg 111, an outer leg 112, and a height-adjustable moving component 113. The outer leg 112 is sleeved outside the inner leg 111. The two ends of the height-adjustable moving component 113 are respectively connected to the inner leg 111 and the outer leg 112, thereby controlling the extension and retraction of the outer leg 112 relative to the inner leg 111. The support frame 12 is disposed above the height-adjustable table leg 11 and is fixedly connected to the outer leg 112. Preferably, there are multiple height-adjustable table legs 11, and each of the multiple height-adjustable table legs 11 is respectively connected to the lower part of the support frame 12. Countertop component 2, such as Figure 6 As shown, the tabletop assembly 2 includes a tabletop 21 and a controllable telescopic structure 22. The lower surface of the tabletop 21 is hinged to one end of the support frame 12. One end of the controllable telescopic structure 22 is rotatably connected to the outer leg 112, and the other end of the controllable telescopic structure 22 is rotatably connected to the lower surface of the tabletop 21.

[0023] The adjustable height table of this utility model is provided with lifting table legs 11 and support frame 12. The lifting table legs 11 drive the support frame 12 to rise and fall. A tabletop 21 is provided and hinged to the support frame 12. The tabletop 21 is rotated by a controllable telescopic structure 22. By sleeved the outer leg 112 on the outside of the inner leg 111 and connecting the controllable telescopic structure 22 to the outer leg 112, the tabletop 21 can still be rotated while rising and falling.

[0024] To drive the support frame 12 to rise and fall, the lifting motion component 113 includes an electric push rod, which includes a motor, a screw, and a sleeve. The screw and the sleeve are connected by a thread, and the motor drives the screw or the sleeve to rotate. The sleeve is installed inside the inner leg 111 and is fixedly connected to the inner leg 111. The motor is fixedly connected to the outer leg 112. More preferably, the motor includes a geared motor.

[0025] To make Desktop 21 multifunctional, such as Figures 2 to 3 As shown, the desktop 21 can be flipped relative to the support frame 12. Preferably, the flipping angle of the desktop 21 is 0° to 100°. When the desktop 21 is flipped along the rotation axis 211, the first end 212 of the desktop 21 moves downward and the second end 213 of the desktop 21 moves upward. The distance L1 between the rotation axis 211 and the first end 212 is more than 0.2 times the distance L2 between the rotation axis 211 and the second end 213. By limiting and optimizing the proportional relationship between the distance L1 between the rotation axis 211 and the first end 212 and the distance L2 between the rotation axis 211 and the second end 213, the support frame 12 can provide sufficient support to the desktop 21 when it is in a horizontal state, preventing the first end 212 of the desktop 21 from flipping under force and affecting the stability of the desktop 21. Simultaneously, when the desktop 21 is tilted or vertical, if the distance L1 between the rotation axis 211 and the first end 212 is less than 0.2 times the distance L2 between the rotation axis 211 and the second end 213, the center of gravity of the desktop 21 will shift to one side, potentially causing the adjustable height table to tip over. More preferably, the distance L1 between the rotation axis 211 and the first end 212 is more than 0.25 times and less than 0.45 times the distance L2 between the rotation axis 211 and the second end 213. In addition to the advantages mentioned above, this design can also significantly reduce the torque required when the controllable telescopic structure 22 flips the desktop 21.

[0026] To improve the efficiency of the controllable telescopic structure 22, such as Figure 3As shown, the distance D1 between the first end 212 of the controllable telescopic structure 22 and the lower surface of the tabletop 21 is greater than the distance D2 between the rotation axis 211 of the tabletop 21 and the outer leg 112. More preferably, the distance D3 between the second end 213 of the controllable telescopic structure 22 and the rotation axis 211 is less than 1.2 times and more than 0.3 times the distance D1 between the first end 212 of the controllable telescopic structure 22 and the lower surface of the tabletop 21. This arrangement ensures that when the controllable telescopic structure 22 extends, its effective distance in the vertical direction is greater than its effective distance in the horizontal direction. In this case, a controllable telescopic structure 22 with a shorter effective distance and smaller dimensions can be selected, which helps to reduce costs and weight. Simultaneously, this arrangement can significantly reduce the force on the hinge point between the controllable telescopic structure 22 and the tabletop 21 in the horizontal direction, preventing the hinge point from loosening after multiple flips.

[0027] To reduce the manufacturing difficulty of the adjustable height table, the inner leg 111, the outer leg 112 and the support frame 12 are made of aluminum profiles.

[0028] To enable the desktop 21 to flip, the controllable telescopic structure 22 includes an electric push rod or a controllable gas spring.

[0029] To extend the lifespan of Desktop 21, such as Figure 6 As shown, the tabletop assembly 2 also includes a reinforcing frame 23, which is fixedly mounted on the lower surface of the tabletop 21, and the support frame 12 is hinged to the reinforcing frame 23. This arrangement ensures that the force exerted by the controllable telescopic structure 22 acts on the reinforcing frame 23. Preferably, the reinforcing frame 23 comprises an aluminum profile.

[0030] To enable the desktop 21 to function as a multi-functional surface, the desktop assembly 2 also includes a whiteboard 24, which is disposed on the upper surface of the desktop 21. When the desktop 21 is tilted or vertically positioned, it can be used as a whiteboard 24.

[0031] To make the adjustable height desk more multifunctional, such as Figure 6 , Figure 7As shown, the tabletop assembly 2 also includes a lamp holder structure 25, which includes a light strip 251 and an L-shaped bracket 252. One end of the bracket 252 is fixedly connected to the light strip 251, and the other end is rotatably connected to the lower surface of the tabletop 21. The bracket 252 is located at the edge of the lower surface of the tabletop 21. This arrangement allows the lamp holder structure 25 to have two states: the first state is that the bracket 252 is not flipped and the light strip 251 is located below the tabletop 21; the second state is that the bracket 252 is flipped and the light strip 251 is located above the tabletop 21. Because the bracket 252 is flipped, it will only flip to the top of the tabletop 21 when necessary, without affecting the normal use of the tabletop 21.

[0032] In order to control the height of the adjustable table legs 11 and the flip angle of the tabletop 21, such as Figure 4 As shown, the adjustable height table also includes a controller 3, which controls the height of the height-adjustable table legs 11 and the extension and retraction of the controllable telescopic structure 22. The controller 3 is installed on one side of the desktop 21. Specifically, the controller 3 is installed at the first end 212 of the desktop 21.
