Description
Technical Field
The invention belongs to the field of office automation, and particularly relates to a stable lifting device for a display.
Background
The existing display is generally fixed on a table top and can not be lifted, so that the display needs to be detached when not in use, dust is easy to accumulate when the display is exposed in the air for a long time, and the space of the table top is occupied by the display, so that the use in space is wasted.
Devices capable of achieving the display lifting function have been continuously available in the market. The traditional display lifting device adopts chain transmission. Its disadvantages are unstable lifting, more greasy dirt, loud noise and need to add lubricating oil in daily use. When the elevation angle is adjusted, a low-power direct current motor is used. Because the motor is used in an overload mode, the motor is easy to burn out, and the repair rate is high. The transmission system is completed by three motors, and the failure rate is high. With the progress of technology, display lifting devices of more structures, such as rack and pinion structures, circular rod bearing structures, steel column track structures, linear tracks, linear bearing structures, and the like, gradually appear.
As shown in the attached fig. 1 of the specification, in a mainstream display lifting device on the market, a lifting support of a display adopts a supporting hinge a1 structure, and guiding on two sides adopts an aluminum alloy profile guiding block a2 matched with guiding. A servo motor a4 for providing lifting power is arranged at the bottom of the device. A servo motor a3 for elevation adjustment is combined with the screen a5, and is located at the upper portion of the support hinge a 1. When the device works, the specific actions are as follows: the servo motor a4 providing lifting power drives the supporting hinge a1, the supporting hinge a1 abuts against the supporting plate at the bottom of the display a5, and the display a5 moves up and down under the guidance of the aluminum alloy profile guide block a 2. After the elevator ascends to the designated height, the elevation angle adjusting servo motor a3 rotates by a corresponding angle, and the elevation angle adjustment of the display a5 is realized.
It has the following problems:
1. the hinge support structure shown in fig. 1 determines that the torque required by the servo motor a4 is larger, which in turn results in larger rated power;
2. with the difference of the lifting height of the display, the form of the hinge supporting structure is changed, and the torque required by the servo motor a4 is changed in a nonlinear way;
3. because the servo motor for adjusting the elevation angle of the display and the display are integrally arranged at the upper part of the support, the weight of a structure needing to be supported is larger;
4. the upper and lower guide structures are unreasonable, so that the friction force is larger;
