Smooth opening and closing of the two-axis hinge

This creation is about a two-axis hinge, especially a two-axis hinge that smoothly opens and closes.

Generally, a clamshell electronic device such as a notebook computer, a mobile phone, etc., is provided with a hinge between the screen and the keyboard of the electronic device to connect the screen and the keyboard and provide the torque required when the screen is opened relative to the keyboard. It was first installed on a clamshell electronic device with a single-axis hinge. Although it can pivot the keyboard to the keyboard, it is limited by the design of the screen and keyboard appearance, the screen casing and the keyboard casing. When it is opened to a certain angle, it will interfere with each other and cannot be opened again. In order to avoid interference, the structure must be moved in the design, and the design is limited.

In order to improve the lack of conventional hinges, the Republic of China Patent No. M388822 is a two-axis pivoting device with a rotational displacement, which is coupled to a screen bracket combined with a first rotating shaft, a base bracket coupled with a second rotating shaft, and a first rotating shaft. Actively rotating around the second rotating shaft, changing the position of the first rotating shaft, so that the first rotating shaft can be displaced upward or backward, thereby driving the screen bracket to move upward or backward, thereby avoiding the screen shell and the base shell when opening Interfere with each other. Although this design can avoid interference between the screen shell and the base shell when it is opened, it can not be opened more than 180 degrees, and it cannot be used in response to the popular electronic devices with touch or handwriting input operations on the market, and has a screen shell and a keyboard shell. It can be flipped more than 180 degrees to facilitate the needs of touch input, or reverse stacking to facilitate the need to hold touch operations.

In order to meet the trend of the current touch electronic device, the present inventor has developed and designed the Republic of China Patent No. M430142, which is a stable opening and closing biaxial hinge, comprising a connecting member and a first rotation disposed on the connecting member. And a second rotating member, the first rotating member includes a first rotating shaft, the first rotating shaft has a first abutting portion and a first positioning groove disposed on the first abutting portion, the first rotating portion The second rotating shaft includes a second rotating shaft, the second rotating shaft has a second abutting portion and a second positioning groove disposed on the second abutting portion, the connecting member includes a first rotating shaft a track portion between the second rotating shaft and a sliding positioning portion disposed on the rail portion, wherein the sliding positioning portion abuts the abutting portions and the positioning grooves in different abutting manners, and The first rotating shaft and the second rotating shaft respectively have a rotation rotation of 180 degrees, thereby enabling the screen of the electronic device to open and close 360 degrees with the base.

However, the sliding positioning portion of the above-mentioned stable opening and closing biaxial hinge is a cylinder, and when displaced along the rail portion, an offset may occur, and the first rotating shaft and the second rotating shaft may not be parallel, and the The first rotating shaft and the second rotating shaft are not smooth when rotated, and a large force is required to be rotated. In the long run, the sliding positioning portion is easily damaged, and the sliding positioning portion needs to be replaced, resulting in waste of cost.

When the electronic device 5 is in an unused state, the display 51 is covered on the base 52. At this time, the ball 33 is pushed by the first abutting portion 141 on the first rotating shaft 11, and the first pressing portion 141 is pressed against the first The second positioning recess 242 of the two shafts 21 is not rotatable by the balls 33 (as shown in FIG. 4-1). When the user applies a force to open the display 51, the first rotating shaft 11 is started to rotate, and the first abutting portion 141 still pushes the ball 33, and the second rotating shaft 21 is restricted by the ball 33. Rotate (as shown in Figure 4-2). The first rotating shaft 11 further has a first limiting portion 111. The first connecting member 31 has a first stopping portion 312. When the display 51 is opened 180 degrees, the first limiting portion 111 receives the first limiting portion 111. The first stopping portion 312 stops to restrict the first rotating shaft 11 from continuing to rotate, and the first positioning concave portion 142 of the first rotating portion 14 is rotated to a position opposite to the second positioning concave portion 242 of the second rotating portion 24. (As shown in Figure 4-3). At this time, a section for the movement of the ball 33 is formed between the first positioning recess 142 and the second positioning recess 242. Then, the display 51 is continuously turned over. Since the first rotating shaft 11 is stopped by the first stopping portion 312 and cannot be continuously rotated, when the display 51 is further turned over, the second rotating shaft 21 is started to rotate and is rotated. The second abutting portion 241 pushes the ball 33 into the first positioning concave portion 142 of the first rotating shaft 11 (as shown in FIG. 4-4 ), thereby allowing the display 51 to be flipped again by 180 degrees. The effect of opening and closing 360 degrees is achieved (as shown in Figure 4-5).

When the user wants to re-attach the display 51 to the pedestal 52, the second reel 21 has a second limiting portion 211, and the first connecting member 31 has a second limiting portion 211. a second stopping portion 313, when the display 51 is turned 180 degrees so that the first positioning concave portion 142 and the second positioning concave portion 242 form the interval, the second limiting portion 211 abuts the second stopping portion 313, in order to restrict the second rotating shaft 21 to continue to rotate, and then continue to flip the display 51, the first abutting portion 141 on the first rotating shaft 11 pushes the ball 33 against the second positioning on the second rotating shaft 21 In the recess 242, the first rotating shaft 11 is allowed to continue to rotate until the display 51 is re-attached to the base 52.

In summary, the present invention utilizes the ball to position and selectively restrict the rotation of the first rotating shaft and the second rotating shaft to achieve a 360-degree opening and closing effect, and due to the appearance of the ball-shaped ball, there is no problem of angular offset. The problem that the conventional biaxial hinge is not smoothly opened and closed is solved, and the surface of the ball can be in contact with the first rotating portion and the second rotating portion due to the shape of the spherical shape, and the wear can be uniformly worn. Extends the life of the use.
