Embodiment Construction

[0034] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as Figure 1-2 Shown is a lifting table 100 with automatic level adjustment function of the present invention, which mainly includes: table board 10, first table leg 20, second table leg 30, first driving mechanism, first motor 40, second driving Mechanism, second motor 50 and controller 60.

[0036] Wherein, the first table leg 20 and the second table leg 30 are connected to the bottom of the table board 10 and located at two ends of the table board 10 to support the table board 10 . The first table leg 20 and the second table leg 30 can be telescopically adjusted to change the height of the table board 10 to the ground, as in the embodiment of the present invention, the first table leg 20 and the second table leg 30 are three-stage telescopic adjustment table legs. The first driving mechanism is connected to the first tab...

Abstract

The invention discloses a lifting table with a function of automatically adjusting the levelness. The lifting table comprises a table plate; a first table leg; a second table leg; a first driving mechanism, which is connected to the first table leg and drives the first table leg to stretch out and draw back so as to adjust the height of the first table leg; a first motor, which is connected to the first driving mechanism to provide driving force for the first driving mechanism; a second driving mechanism, which is connected to the second table leg and drives the second table leg to stretch out and draw back so as to adjust the height of the second table leg; a second motor, which is connected to the second driving mechanism to provide driving force for the second driving mechanism; and a controller, which is electrically connected to the first motor and the second motor to control the first motor and the second motor. The controller adjusts the duty ratio of the first motor and / or the second motor according to the height difference between the first table leg and the second table leg so as to reduce the height difference. According to the lifting table with the automatic levelness adjusting function, the duty ratio of the motor can be automatically adjusted according to the height difference of the table legs, so that the height difference of the table legs is reduced, and the table plate is kept horizontal.

Description

technical field [0001] The invention relates to an elevating table with the function of automatically adjusting the level. Background technique [0002] In the traditional automatic lifting table, the legs of the table are powered by a DC motor plus an encoder, and multiple table legs rise or fall at the same time to drive the desktop up and down. Since each table leg is independently controlled, synchronous control processing is required between the table legs, and the height difference between the table legs during the rising / falling process needs to be small enough to ensure the level of the tabletop. Out-of-sync between table legs can cause the table top to tilt, posing a safety hazard. Contents of the invention [0003] The invention provides a lifting table with the function of automatically adjusting the level, adopting the following technical scheme: [0004] A lifting table with automatic level adjustment function, comprising: [0005] desktop; [0006] The fi...
