On the other hand, the first fixing frame 41 is rotatably socketed on the first joint 222 of the first pivot 22, the second fixing frame 42 can be fixedly sleeved in the second joint 232 of the second pivot 23, so that the first fixing frame 41 rotates the first opening angle θ 1 (Fig. 5) relative to the first pivot 22, connection bracket 1 is rotated the second opening angle θ 2 (Fig. 5) relative to the second pivot 23; Particularly, in the present embodiment, the first fixing frame 41 and the second fixing frame 42 have respectively a side that circular perforation 411,421, second fixing frame 42 is adjacent to connection bracket 1 and are more provided with a positioning ring 6 with non-circular perforation 61.It should be noted that the diameter due to the circular perforation 411 of the first fixing frame 41 is greater than the first joint 222, thus the first fixing frame 41 can freely rotate relative to the first pivot 22, and with the first pivot 22 with moving.In addition, because the shape of the non-circular perforation 61 of positioning ring 6 is identical with the second joint 232 section configurations, therefore the second fixing frame 42 is fixedly arranged on the second joint 232 and with the second pivot 23 with moving; In other words, connection bracket 1 can freely be rotated relative to the second fixing frame 42.
Please consult again Fig. 1 and Fig. 3 A, the first fixing frame 41 of the utility model double-shaft type pivot device 100 and the second fixing frame 42 can be distinguished lock seaming in upper cover 201 and the lower cover 202 of electronic equipment 200; On the contrary, the first fixing frame 41 and the second fixing frame 42 also can be distinguished lock seaming in lower cover 202 and the upper cover 201 of electronic equipment 200.In the present embodiment, the first fixing frame 41 lock seaming of the utility model double-shaft type pivot device 100 are in the upper cover 201 of electronic equipment 200, and rotate socket and each autorotation with the first joint 222 of the first pivot 22, the second fixing frame 42 lock seaming are in the lower cover 202 of electronic equipment 200, and fixedly sleeved and together rotate with the second joint 232 of the second pivot 23.Stop mechanism 3 have one first backstop wheel 31 and 1 second backstop wheel 32 respectively fixedly sleeved the first joints 222 and and the second joint 232 on together rotate; Wherein, the first backstop wheel 31 is between the first pivot 22 and the first fixing frame 41, and the second backstop wheel 32 is between the second pivot 23 and connection bracket 1.Limit structure has one first spacing block set 412 and one second spacing block set 12; Wherein, on the first fixing frame 41, evagination forms the first spacing block set 412, and in connection bracket 1, evagination forms the second spacing block set 12.In the present embodiment, first backstop wheel the 31 and second backstop wheel 32 has respectively one first sector unit 311 and one second sector unit 321, and first backstop wheel the 31 and second backstop wheel 32 respectively can be respectively in the first opening angle θ 1 (Fig. 5) and the second opening angle θ 2 (Fig. 5) interference with the first spacing block set 412 and the second spacing block set 12, to limit respectively the first fixing frame 41, relative to the first pivot 22, rotate the first opening angle θ 1 and connection bracket 1 is rotated the second opening angle θ 2 relative to the second pivot 23.
It should be noted that because connection bracket 1 and the first pivot 22 are with moving, therefore the first opening angle θ 1 is the first fixing frame 41 and connection bracket 1 angle in relative rotation; More specifically, the first opening angle θ 1 is the first spacing block set 412 relative to the first backstop wheel 31 angles of rotating (i.e. the rotation angle of the first spacing block set 412 between the first sector unit 311 two ends); Similarly, because the second fixing frame 42 and the second pivot 23 are with moving, therefore the second opening angle θ 2 is the second fixing frame 42 and connection bracket 1 angle in relative rotation; More specifically, the second opening angle θ 2 is the second spacing block set 12 relative to the second backstop wheel 32 angles of rotating (i.e. the rotation angle of the second spacing block set 12 between the second sector unit 321 two ends).
In sum, the utility model double-shaft type pivot device 100, by the rotation mode of second order segmentation, sequentially rotates the first pivot 22 and connection bracket 1, and then makes the upper cover 201 of electronic equipment 200 and lower cover 202 can relatively rotate 360 degree to oppositely superimposed; Wherein, because the first opening angle θ 1 is less than 180 degree, and the first fixing frame 41 freely rotates relative to the first pivot 22, therefore while opening in the first stage (the first fixing frame 41 rotates the first opening angle θ 1 relative to the first pivot 22), the torsion rotating is less, the required strength applying of user's hand is less, compared with leicht fallen D/A; And when when second stage is opened (connection bracket 1 is rotated the second opening angle θ 2 relative to the second pivot 23), because the first spacing block set 412 of the first fixing frame 41 is resisted against the first backstop wheel 31 of the first pivot 22, therefore the torsion rotating is larger, the required strength applying of user's hand is larger, effort.In the present embodiment, preferably, the first opening angle θ 1, between 90 degree to 180 degree, makes the relative lower cover 202 inclination first opening angle θ 1 of upper cover 201 of electronic equipment 200, and has good watching angle.On the contrary, because the first spacing block set 412 rotates the first opening angle θ 1 on the first sector unit 311, and the second spacing block set 12 rotates the second opening angle θ 2 on the second sector unit 321, therefore the first sector unit angle θ 3 is greater than 180 degree, the second sector unit angle θ 4 is less than 180 degree, makes the summation of the first sector unit angle θ 3 and the second sector unit angle θ 4 approach 360 degree.
On the other hand, the utility model double-shaft type pivot device 100, two axis holes 11 that run through formation due to connection bracket 1 are oblique setting, that is two the online of axis hole 11 centers be oblique, therefore the first pivot 22 and the second pivot 23 are also oblique setting, therefore when the first pivot 22 and the second pivot 23 are connected to respectively the upper cover 201 of electronic equipment 200 and lower cover 202, the utility model double-shaft type pivot device 100 has preferably application, can be applied on the thinned electronic equipment 200 that twin shaft is oblique setting.
Again on the one hand, the utility model double-shaft type pivot device 100, because two fixing frames 5, connection bracket 1 and stop mechanism 3 be arranged in parallel in fact, therefore can effectively make the thickness attenuation of whole double-shaft type pivot device 100, volume reduces.
