Universal desktop support for notebook computers and tablet computers

technical field

The invention relates to a general-purpose desktop bracket for notebook computers and tablet computers, which is suitable for use on desks and desktops, and belongs to an auxiliary accessory for notebook or tablet computers.

technical background

With the advancement of science and technology, the continuous improvement of computer manufacturing level and the popularization of computer technology, various types of computers are widely used in human's daily work and life. Compared with traditional desktop computers, notebook computers and tablet computers are becoming more and more popular among business people, company employees, engineering and technical personnel, scientific research workers and teachers due to their advantages such as small footprint, portability, convenient use, and energy saving. The choices of students, students, and even ordinary people are playing an increasingly important role in people's daily work and life. Compared with common desktop computers, these two kinds of computers are famous for their portability, but in daily use, they are placed on desks and desktops just like desktop computers. While they bring convenience and quickness to users, they also bring huge health risks. Taking the most widely used 14 o'clock notebook computer as an example, the height of the screen varies within the range of 9-12cm, and the thickness of the mainframe of the notebook computer is 1.5-2cm, and the height of the top edge of the screen is at most 15cm above the desktop. about. And when an adult sits on the chair in front of the desk with the most healthy sitting posture (straight waist, neck, eyes looking straight ahead), the height of the eyes from the desktop is about 40cm. Like this, when using, the user just is forced to bow or bend over. Over time, the user's cervical spine and lumbar spine will suffer from muscle strain due to long-term tension. What's more, it will lead to diseases such as spinal dislocation and compression of nerves, which will seriously damage the health of users. This phenomenon will be more serious when the user is using a tablet computer placed flat on the desk surface.

For this reason, many inventors try to raise the rear portion of notebook computer by various devices to lift the position of notebook computer screen and minimize the user's degree of bowing or bending over, to reduce the health threat to the user. For example, invention patent 200910011629.5 discloses a "2"-shaped or "E"-shaped notebook cooling rack made of metal, plastic or other materials; utility model patent 200820134521.6 discloses a foldable notebook cooling rack; utility model 200920169322.3 announced a simple notebook heat sink with U-shaped height adjustable in 3 sections. Other utility model patents, such as 200930162668.6, 200930139302.7, 200930139303.1 and 200630058556.2, also raise the rear of the notebook in a similar manner to improve the display screen of the notebook computer. However, all the notebook computer brackets involved in the patents have the disadvantages of limited elevation range or adjustable elevation range in several steps, which cannot realize the continuous adjustment of the height of the display screen of the notebook computer, so that it cannot meet the needs of different users in a wider range. The needs of tall users, such as users whose height is above 1.8m.

Aiming at the use of tablet computers, the utility model patent 201020208183.3 has announced a special bracket for tablet computers that is very similar to notebooks: it is concave in the place where the original notebook screen is placed, and is used to place the tablet computer; The keyboard is as effective as using a notebook on a desk. The use effects of other utility model patents such as 201030253137.0, 201030253137.0 and 201030585610.5 all allow the tablet computer to be placed on the desk desktop at a certain angle. However, the overall use effect of these utility model patents is also similar to 201020208183.3, thus eliminating a relatively large hidden danger to the health of users.

Also, all existing tablet mounts are not suitable for laptops. Therefore, when a tablet computer user still needs to separately purchase a special-purpose notebook computer stand separately for the notebook computer purchased after oneself. For notebook users, although the existing notebook computer bracket can be used to place the purchased tablet computer, the placement effect is similar to that of the utility model patent 201020208183.3: because the position of the tablet computer is still too low, it cannot solve the above problems The user needs to lower his head or bend over to use it, which poses a potential threat to the health of the user.

In addition, when using the stand involved in the above-mentioned patent, there is also a common problem: when using the existing stand to raise the rear of the notebook as much as possible or make the tablet stand obliquely on the desk desktop, use the keyboard or keyboard that comes with the notebook computer. It has become extremely inconvenient to enter various information on the touch screen of a tablet computer, and an external wired or wireless keyboard is often required for entry. Since the surface of the external keyboard is more than 1cm higher than the desktop of the desk, when using it, the user often needs to put his arms flat on the desktop of the desk, and then lift his hand slightly upward to complete the input work. If things go on like this, the tendon tissue on the back of the hand near the wrist will be strained due to long-term tension, which will cause various inflammations and damage the health of the user.
