Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

Referring to fig. 1 and 2, the present invention provides a dual-shaft co-acting hinge 100, wherein the dual-shaft co-acting hinge 100 comprises a mounting seat 10, two transmission shafts 20 horizontally disposed on the mounting seat 10, and a cover plate 40 disposed on the mounting seat 10. Specifically, the mounting base 10 is formed with an accommodating space 11 and two rails 12 respectively located at one side of the mounting base 10 and communicating with the accommodating space 11 for one of the transmission shafts 20 to be disposed. On the other hand, each transmission shaft 20 has a shaft body 21, and transmission ribs 22 respectively corresponding to the receiving spaces 11, a slider 23 disposed on the shaft body 21 and corresponding to one of the rails 12, a baffle 24 disposed on the shaft body 21 and connected to the slider 23 and corresponding to one of the rails 12 so that the rail 12 cannot be seen from the outside, an assembling plate 25 connected to the baffle 24, and a torsion assembly 26 disposed on the shaft body 21. Furthermore, the sliding block 23, the blocking plate 24 and the assembling plate 25 can be integrally formed and combined into a fixing bracket 28. Further, each rail 12 has an open end 121 and a restricting end 122 that restricts displacement of the slider 23 therein.

In detail, the mounting socket 10 is formed with at least two first coupling holes 13, and the cover plate 40 is formed with two second coupling holes 41 respectively corresponding to the first coupling holes 13, wherein the first coupling holes 13 and the second coupling holes 41 are used for coupling the mounting socket 10 and the cover plate 40. One end of each shaft body 21 principle transmission convex rib 22 is respectively provided with a reducing part 211 and two assembling planes 212 which are respectively formed on one side of the reducing part 211. Each baffle 24 is formed with a first through hole 241 corresponding to the reduced diameter portion 211 for penetration. In addition, the driving convex ribs 22 extend towards the other driving shaft 30 respectively, and radially and alternately extend above the shaft body 21, any two adjacent driving convex ribs 22 on each driving shaft 20 define an accommodating gap 27, and further, each driving convex rib 22 is staggered in one accommodating gap 27 on the other driving shaft 20, so that the two driving shafts 20 generate a direct driving relationship. In one embodiment, the transmission rib 22 is not disposed at the end of the transmission shaft 20 facing the other transmission shaft 20, in other words, the transmission rib 22 is disposed on the shaft body 21 at a position having a certain distance from the end of the transmission shaft 20.

Referring to fig. 1 to 3, when the dual-shaft simultaneous movement hinge 100 is assembled, each transmission shaft 20 is sequentially disposed on the mounting seat 10, the transmission convex ribs 22 of the two transmission shafts 20 are located in the accommodating space 11, and the transmission convex ribs 22 are assembled to form a transmission state, as shown in fig. 3, a fixing bracket 28 is mounted on each transmission shaft 20, each fixing bracket 28 is respectively sleeved on the reduced diameter portion 211 of one of the shaft bodies 21, and each sliding block 23 enters one of the rails 12 at the same time, and then the torsion assembly 26 is mounted. After the assembly is completed, each baffle 24 will shield one of the rails 12 correspondingly disposed, thereby achieving the purpose of hiding the rails.

Referring to fig. 2 to 6, the dual-shaft simultaneous movement hinge 100 of the present invention has an open state and a closed state, wherein fig. 1 is the open state of the dual-shaft simultaneous movement hinge 100, and fig. 6 is the closed state of the dual-shaft simultaneous movement hinge 100. Here, assuming that the dual-axis simultaneous movement hinge 100 is in the closed state, when the assembling plate 25 is pushed to rotate the corresponding one of the transmission shafts 20, the blocking plate 24 drives the sliding block 23 to slide from the limiting end 122 toward the open end 121, and at this time, the transmission rib 22 drives the transmission rib 22 on the other transmission shaft 20, so that the driven one of the transmission shafts 20 rotates in the opposite direction. When the two transmission shafts 20 continue to rotate until each slider 23 contacts two stopping surfaces 42 facing the open end 121 and limiting the displacement of the slider 23, the two sliders cannot move and enter the closed state.

Specifically, the assembling plates 25 of the two transmission shafts 20 can be assembled to the notebook computer main body 60 and the screen 70, respectively, and when the user applies a torque to the screen 70 to turn the screen 70 toward the notebook computer main body 60, the dual-axis simultaneous movement hinge 100 will generate a height change along with the turning angle of the screen 70, as shown in fig. 4 to 6.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
