Description

Two-axis pivot

The present invention relates to a two-axis pivoting device, in particular to a two-axis pivoting device capable of freely adjusting a rotation angle and increasing a rotation angle, and is applied to a support frame of an electronic device to provide electronic device flipping use.

The development trend of computers is evolving in a portable direction. All manufacturers are eager to develop computers that can be carried around and can be operated anytime and anywhere. Power lasting and computing efficiency are necessary considerations, which depends on the development of power-saving by semiconductor industry. Components, as well as battery manufacturers, have developed high-capacity batteries.

However, the mechanism that is not limited by the venue depends on the design of the system design manufacturer. The current notebook computer adopts a two-piece body folding method. One body is a computer screen, and one body has a keyboard. Vertical, it is quite convenient to use on the table, but it is not suitable for holding on the hand.

The current solution is to use a tablet computer as the main axis. The so-called tablet computer is designed with the screen on the top of the body. The user can hold the computer with one hand and click the function button or writing content on the touch screen with the stylus.

Although the tablet can be operated on the palm, many important tasks of the computer are related to text input. The tablet uses the stylus writing method as the main input method. This method is slower and harder than the original keyboard input, although it is convenient to carry. There has been a lot of progress, but the convenience of input is a kind of retrogression, so many people are not optimistic about the development of tablets, and therefore the tablet is also limited. Special uses, such as doctors ward, warehouse inventory, etc., only need to check the options, less text input purposes.

In order to solve the input problem, some tablets will design a fan-shaped keyboard table on the touch screen. The user double-handles the computer and performs the pressing action with the thumb of both hands, but the movement range of the thumb is held by the two hands. Restricted, plus the thumb is a bit clumsy, so the speed of operation is far less than the general physical keyboard.

Another design uses a slide-out physical keyboard. When a large amount of text input is required, the hidden physical keyboard can be slid out for use. However, this method needs to be the same as the touch-sensitive keyboard on the screen. The finger holds the computer and operates with a clumsy thumb. When the hand is held by the keyboard and the extended screen, the center of gravity of the computer falls outside the hands. The gripper is very hard and unable to lasting.

Therefore, if the electronic device such as a notebook computer can be converted into a tablet computer structure by changing the structural design, it has become an urgent problem to be overcome.

It can be seen that there are still many shortcomings in the above-mentioned conventional two-axis hinges, which is not a good designer and needs to be improved.
