Description

Technical Field

[0001] The utility model belongs to the field of intelligent home furnishing, in particular to a suspended induction lifting table. Background Art

[0002] Automatic lifting tables generally use electricity as their power source, and the height of the lifting table is adjusted by controlling the mechanical device through an electric motor. The currently commonly used lifting method mostly utilizes the mutual engagement of worm gears to control the rotation of the lead screw, thereby achieving a change in the length of the table legs. Since the table legs on both sides need to be lifted and lowered, two motors are required during control. This method enables two controls, and can make the installation spacing between the two table legs not fixed, which is more flexible. However, this method is fixed, which increases the number of motors and, therefore, increases the maintenance cost.

[0003] The existing electric lifting tables on the market mainly rely on the size of the passing current to detect anti-pinch and anti-collision and motor stalling. When the anti-pinch and anti-collision are triggered, the motor will instantly stall and generate overcurrent, or use a gyroscope. When the product encounters an obstacle, the MEMS chip will respond instantly. However, all of the above technologies can only detect foreign objects after the table actually hits an obstacle, so the current collection and MEMS technology requirements are particularly high. Once the reaction is slow, it will squeeze or crush the items under the table.

[0004] In summary, the utility model provides a suspended induction lift table to solve the above problems. Utility Model Content
