Description

Synchronous opening and closing of the two-axis hinge 【0001】

This creation is about a two-axis hinge, especially a two-axis hinge that can be opened and closed simultaneously.

【0002】

A cover-type electronic device, such as a notebook computer or a portable telephone, is provided with at least one hinge between the display module and a body to connect the display and the body. The action of opening or closing relative to the body. The early hinges were mainly single-axis hinges with a single rotating shaft as the rotating axis. Although the effect of opening and closing the display relative to the body was produced, the single-axis hinge could not be opened at a large angle. After the angle is turned on, the display and the body interfere with each other and cannot be continuously opened, which greatly limits the openable angle of the clamshell electronic device.

[0003]

In order to improve the lack of the aforementioned single-axis hinge, a manufacturer has proposed a hinge that is implemented in a two-axis. For example, in the Republic of China, the new patent No. M428642 discloses a two-axis type horizontal drop-free hinge and a portable device thereof, including an upper rotating frame, a lower rotating frame and a plurality of gears disposed in a gear chamber. Through a gear ratio between each of the gears, an upper cover mounted on the upper rotating bracket and a base mounted on the lower rotating bracket can be opened at 180 degrees. However, although the above-mentioned two-axis hinge implemented by the gear structure can overcome the disadvantages of the single-axis hinge, the implementation of the plurality of gears will lead to difficulty in designing the gear ratio, and the design needs to consider the gear ratio and the tooth of each gear. Distance parameters. In addition, in the process of turning the two-axis hinge implemented by the gear in the process of turning on, there is also a problem of the idle stroke, which needs to be improved.

[0004]

The main purpose of this creation is to provide a simple moving double-axis hinge.

[0005]

To achieve the above object, the present invention provides a synchronous open and closed biaxial hinge including a support frame, a first rotation shaft, a second rotation shaft and at least one interlocking ball.

Furthermore, the second rotating shaft 3 includes a second receiving portion 31 and a pair of second spiral tracks 32 which should be accommodated in the second rotating shaft 3 with the second rotating shaft 3 as an axis. . Further, the spiral direction of the first spiral track 22 may be opposite to the spiral direction of the second spiral track 32, thereby enabling the interlocking ball 4 to interlock the first rotating shaft 2 or the second with less labor. Rotate the shaft 3. In addition, the first receiving portion 21 and the second receiving portion 31 of the present invention can be respectively assembled with a display or a main body of the notebook computer. The interlocking ball 4 is disposed in the receiving area S and respectively contacts the first spiral track 22 and the second spiral track 32, so that the first rotating shaft 2 and the second rotating shaft 3 are mutually The linkage corresponds to flipping.

[0017]

Further explain the implementation process of the biaxial hinge of this creation, please refer to Figure 1 to Figure 4, and please refer to Figure 5-1 and Figure 5-2. In order to clearly explain the implementation process of the present invention, the interlocking ball 4 is pre-defined to contact the position of the first spiral track 22 and the second spiral track 32 as a starting position L1 when the biaxial hinge is not opened. After the biaxial hinge is opened 180 degrees, the contact position of the first spiral track 22 and the second spiral track 32 is an open position L2. It is assumed that the user uses the first receiving portion 21 as a point of application so that the first rotating shaft 2 interlocks the second rotating shaft 3. In the case that the biaxial hinge is not opened, the interlocking ball 4 is normally located at the starting position L1, and when the user applies the force to the first receiving portion 21, the edge of the first spiral track 22 is pushed. The interlocking ball 4 is gradually moved toward the open position L2. At the same time, the interlocking ball 4 is pushed against the edge of the second spiral track 32 and displaced at the same time. On the second spiral track 32, however, the interlocking ball 4 is displaced on the second spiral track 32, and at the same time, the second rotating shaft 3 is inverted relative to the first rotating shaft 2. When the user continues to apply force to the first receiving portion 21, and the interlocking ball 4 is finally displaced in the open position L2, the first rotating shaft 2 is opened 180 degrees with respect to the second rotating shaft 3. However, the present embodiment is only exemplified by opening 180 degrees, but in fact, the biaxial hinge can be implemented to perform 360 degree opening, and the implementation process is the same as the defined position difference of the opening position L2. Furthermore, the closed embodiment of the biaxial hinge is the reverse implementation of the above embodiment, and will not be described herein. Furthermore, the present embodiment is mainly described by a single interlocking ball 4, but the present invention can also provide a plurality of interlocking balls 4 in the housing area, for example, two interlocking balls.
