The present invention relates to an automatic pop-up shaft device, in particular to a rotating shaft device applied to a mobile device such as a notebook computer, which can automatically pop the tripod to a set angle, so that the user can move the tripod to different operating angles. position.

Since a mobile device such as a tablet computer usually has to be used in a double-handed grip, it is not only prone to fatigue, but even when placed in a position such as a lap, there is often a phenomenon of swaying and slipping, which is troublesome to the user's operation. To improve this shortcoming, the most common way is to install a support stand for supporting such a mobile device with a stand up angle, which is a convenient and stable and labor-saving state of operation.

In such a tablet mobile device with an existing support stand, the support stand usually has one end pivotally positioned with the tablet, and the other end is a movable force end, which can be flattened and folded on the tablet when the whole stand is not in use. On the back side of the device, or in use, the pivotal positioning end of the tripod is pivoted into various support angles.

However, when such a support stand provided in a mobile device is not used, it is close to a back surface such as a tablet computer in a flat manner, and the gap between the two is very small, and in the case where the user's finger is relatively large, It is very troublesome and inconvenient to operate by pulling the support stand away from the positioning state before use and applying force to open the stand at an angle.

The purpose of the present invention is to provide an automatic pop-up pivoting device, which can automatically push the tripod into a set opening degree after the tripod is disengaged, so that the user can rotate the tripod. Go to the desired operating angle position.

As shown in FIGS. 2 and 3, the torsion and spring biasing mechanism includes a biasing mechanism formed by two pairs of biasing members 30 and 40. The surface of the biasing mechanism is coupled to the engaging piece 102 and can The bolts are integrated into one body through the opposite through holes; a torque generating device 50 is assembled and positioned The torque is generated by the deflection of the biasing mechanism in the biasing mechanism. In this embodiment, the torque generating device 50 includes a unitary torsion member 51 and a guiding rod 52. The unitary torsion member is configured. 51 is provided with a front end torque through hole 53, a rotating shaft 54 is inserted into the torsion through hole 53, and the two ends of the rotating shaft are respectively positioned on the opposite through holes 31, 41 of the two pairs of biasing members 30, 40. In the illustrated embodiment, the torsion through hole 53 is a circular through hole containing a torsion notch, and the rotating shaft 54 is set to be a shaft having a top and bottom cut plane for forming different when rotated to different angular positions. The radial length is forcibly pressing the torsion through hole 53; the guiding rod piece 52 is fixedly coupled to the rear end of the unitary torsion member 51 in a conventional outwardly extending manner, and is provided with an end shaft 55 for the end shaft The two ends of the 55 are respectively combined and combined with the opposite stroke guides 15 of the two pairs of half shells 10, 20. The two pairs of semi-bias members 30, 40 are movably coupled to the opposite arc grooves 13, 23 of the two pairs of half-shells 10, 20 via the outer predetermined curved rails 32, 42 and are guided by another guide post. 33, 43 are engaged with the guide grooves 14, 24 of the two pairs of half-shells 10, 20 to limit the deflection stroke; at the same time, a pair of opposing pressing members 34 are provided near the front end of the two pairs of biasing members 30, 40. And a 44-integrated compact, an elastic member 60 is provided with a positioning end 61 and a pressing end 62, and the second bolt 104 for assembling the two pairs of half-shells 10, 20 can be positioned through The elastic member 60 has the positioning end 61 positioned therein and the pair of partial housings 10, and the other pressing end 62 is pressed against the surface of the pressing block. In this embodiment, the two pairs of half-shells 10, 20 are provided with opposing holes 17, 17 for positioning the elastic member 60, and one of the holes 17 is provided with a slot 18 for movable insertion of the positioning end. 61.

As shown in FIG. 4, according to the above configuration, in the untwisted normal state, the end shaft 55 at the rear end of the torque generating device 50 will be positioned in a position close to the horizontal direction of the opposite stroke guide 15 in a near horizontal direction. The entire engaging piece 102 is forcefully disengaged in the direction of the arrow and interlocks with the biasing mechanism formed by the two pairs of biasing members 30, 40. At this time, the single-piece torsion member 51 is provided with the torque through hole 53. The torsion generated by the biasing will cause the end shaft 55 to generate an idle stroke on the opposite stroke rail 15 as shown in FIG. 5, so that the engaging piece 102 and the biasing mechanism formed by the pair of half biasing members 30, 40 are gradually deflected outward. At this time, the above-mentioned pressing block formed by the combination of the two opposing pressing members 34, 44 will be inclined with the yaw action, and the pressing end 62 of the elastic member 60 can thereby join the engaging piece 102 together with the two pairs of the biasing members 30. The biasing mechanism formed by 40 automatically pops out the elastic opening angle as shown in Fig. 5, so that the user can continue to open to the different positioning angle positions required as shown in Fig. 6, and go out During the process of opening a large angle, the torque generated by the unitary torsion member 51 can be positioned, and at the maximum opening angle, the plurality of stop points, including, for example, the guide posts 33, 43 can be reached at the maximum opening angle. The ends of the guide grooves 14, 24 of the housings 10, 20 and the end shafts 55 reach the ridges 151 of the stroke guide 15 to strengthen the stops. On the contrary, after use, the engaging piece 102 can be closed back together with the biasing mechanism formed by the pair of half biasing members 30, 40 along the reverse process described above.

As shown in FIG. 7, the engaging piece 102 can be assembled with a tripod 70, and at the same time, positioning means (such as relative magnet pieces) 71, 81 can be respectively disposed at the opposite positions of the stand 70 and the back of the mobile device 80. The tripod 70 is folded during use. After the user opens the positioning device 71, 81, the entire tripod 70 can automatically slide a set angle (for example, about 30), and then the tripod 70 can be opened to the desired tilt angle position.

The present invention thus provides an automatic pop-up pivoting device that eliminates the need for the user to dial the entire tripod 80 with a very large finger on the extremely narrow stand 70 and the mobile device 80, and can automatically play the stretch after positioning. The bounce angle of the convenient force is quicker and more convenient in the operation of the stand 70.
