Although the history of the standing desk, can be traced back to the late 18th century (Wikipedia mentions Thomas Jefferson, the third president of the United States, in his writings). Electric standing desk has become popular in the past 5 years. Especially during the COVID-19, people's attention to electric standing desk has reached the highest level. Many blog articles mention the help of electric standing desk for health.
In this articles, consumers should understand, how does the electric standing desk work before choosing a desk.
Through the below seven points, you can understand the real working principle of a electric standing desk.
First, a electric standing desk use 110v to 240v daily voltage as power supply, it can be used in any country around the world.
Second, Use 12v or 24V or 36v or 48v permanent magnet DC motor as driving power source;
Third, After the power is supplied to the motor, the motor rotates, and the motor worm and turbine perform one-stage deceleration;
Forth, The worm gear pad is fixed on the turbine, and the worm gear connection head drives the transmission rod to rotate, and the rotation of the transmission rod drives the first-level screw to rotate.
Fifth, A secondary nut is installed on the top of one pole screw rod, and the rotation of the primary screw rod drives the middle tube up or down;
Sixth, The secondary screw rod is connected with the lifting column through the top plate. When the primary screw rod rotates, the secondary screw rod is driven to rise, making the lifting column move up and down linearly;
Seventh,By switching the positive and negative poles of the DC motor, the motor will rotate forward or reverse to realize the lifting and lowering of the desk.
As a manufacturer of smart furniture, our company's electric standing desk mainly include two types, one is the dual motor standing desk, Another is the single motor standing desk. These types are similar with best-seller in Amazon.
Below we take the single motor standing desk as an example to see the components in detail.
First of all, the entire table can be divided into three different parts, they are tabletop, supporting part, and driving system.
The desktop is a relatively independent part. When purchasing an electric standing desk, you can choose a standing desk with a desktop, or standing desk frame only. There are many choices for tabletop material and size for options. I will not expand it here. Maybe I will write another article for introduction.
The supporting parts are the most important parts of the entire electric standing desk, and it is the key aspect to measure the supporting performance. The supporting parts include table foot, lifting columns, side frames, and supporting beams.
The different designs of the foot and the lifting column, will bring a different appearance to the standing desk.
The first is, the table foot and the lifting column have different shape. Commonly, table foot have anti-kick designs or curved heads. The columns can be rectangular, square, round or oval (commonly found in kids adjustable desk).
The second is the connection position of foot and column. The two most common design methods are symmetrical design and asymmetrical design.
The symmetrical design means that the position where the lifting column connects to the table foot is in the middle. The advantage of this design is that the entire table looks stable, but it is not novel in appearance.
The asymmetric design means that the position where the lifting column connects to the table foot is not centered, it places on a position, which divide the foot proportionally, and the side frame connecting the lifting column is also changed in the same way. The conventional ratio is 30:70, or 40:60. This design makes the appearance of the electric standing desk unique.
The benefit is, the support beams will not be in the middle of the desktop. In this way, the front part of the desktop will have more space to install accessories, like keyboard tray.
Driving system is the core part of the electric standing desk. The main components include DC linear drive motor, control unit, drive rod and screw, and hand controller.
Input voltage of the DC linear actuator motor is generally DC 12V or 24V. The performance of the motor determines the overall performance of a standing desk. Such as working mechanism, noise level, overload protection, push-pull force and full load speed.
The control unit is an important indicator to measure the intelligence of an electric standing desk. It is mainly composed of power supply and controller. Most electric standing desks are equipped with a wide-range power supply, suitable for use around the world, adapting to 110V to 240V voltage.
But the controller is configured differently according to the product level. Single motor electric standing desk is equipped with the most basic controller, in consideration of economic performance. Dual motor standing desk is equipped with an intelligent controller.
The driving rod is composed of a hexagonal aluminum rod and connecting pieces. DC motor is connected to driving rod, which is fastened by a connecting piece, and the two ends are connected with the screw in the lifting column. DC motor drives up or down to make the lifting column up and down.
The hand controller (we also call it handset) is the unit for inputting instructions.
Handset can realize the function of ascending and descending, and setting the specified memory height. When ascending or descending to any height, the user only needs to press the ascending or descending key to realize the function. When running to the designated memory height, you only need to press the memory function key once, and the electric standing desk will automatically perform the operation, which is very convenient.
Electric standing desk can be divided into single motor standing desk and dual motor standing desk, according to the number of driving motors. As per the size of the adjustable height range, it can be divided into two stages and three stages.
Generally speaking, dual motor standing desk is better than single motor standing desk standing desk, because it adopts an intelligent control system and two motor drives. But the price will be higher.
The intelligent control system includes monitoring anti-collision and dynamic balance, overload protection and thermal protection function. In addition, the noise level of dual motors is lower and the operation is more stable.
The height adjustment range of the dual motor three stage standing desk is wider, from 560mm to 1210mm, which can meet users who need a wide range of adjustment height.
However, with the continuous improvement of synchronization technology, the technology of single motor standing desks has been greatly improved.
There has also been considerable progress in operational stability. And operating noise become close to dual motor desk. Moreover, it has excellent cost performance, due to one motor to drive. Single motor standing desk is becoming the first choice of health office furniture.
