However, the transmission efficiency between the upper and lower transmission members and the transmission body is not good, and a large transmission load is generated. The user needs to use a large force to pull the upper cover display end of the electronic device or the host system end to connect the first pivot with The second pivot rotates relative to each other. When the display end of the upper cover and the system end of the main system are opened and closed, the cam gradually faces the concave wheel, so that the display end of the upper cover and the system end of the main system are automatically closed to generate a closed feeling, but a larger transmission load causes the display end of the upper cover. The automatic closing with the host system side becomes dull and affects the feeling of closure, which in turn causes the user to feel a clear sense of closure.

In view of the above problems of the prior art, which cannot be effectively solved and overcome, the present applicant has filed this patent application to solve the aforementioned problems.

The problem to be solved by the present invention is that a large transmission load may make the automatic closing of the display end of the upper cover and the end of the main system system dull and affect the feeling of closure, thereby causing the user to feel a clear sense of closure.

The first shaft is connectable to the upper cover display end of the electronic device, and the second shaft is connectable to the host system end of the electronic device. The transmission gear set drives the first shaft and the second shaft by using the first gear, the second gear and the at least one driven gear, which has better transmission efficiency, thereby reducing the transmission load. The user does not need to use a large force to pull the upper cover display end of the electronic device and the host system end to rotate the first shaft and the second shaft relative to each other. When the upper cover display end and the host system end are opened to close, the first latching member and the second latching member are gradually latched toward the first positioning plate, so that the upper cover display end and the host system end are automatically closed. A closed feeling is generated, and the upper cover display end and the host system end are not automatically affected by the lower transmission load, and the user automatically feels a clear closed feeling.

In summary, the dual-axis hub of the present invention has the following advantages:

1. The first shaft 10 is connectable to the upper cover display end of the electronic device, and the second shaft 20 is connectable to the host system end of the electronic device. The transmission gear set 30 is separated from the first friction plate 32 by a distance D, the second gear 35 and the second friction plate 33 are separated by the distance D, and the first connecting member 31 and the second connecting member 37 respectively have a gap between opposite ends of the at least one driven gear 36, so that the first gear 34, the second gear 35 and the at least one driven gear 36 drive the first shaft 10 and When the second shaft 20 is used, it has better transmission efficiency, thereby reducing the transmission load. The user does not need to use a large force to pull the upper cover display end of the electronic device and the host system end to rotate the first shaft 10 and the second shaft 20 relative to each other.

2. When the display end of the upper cover and the system end of the main system are opened and closed, the pivotal position of the dual-axis pivot gradually changes from the pivoting position to the position of the latch, so that the display end of the upper cover and the system end of the main system are automatically closed to generate a closed feeling. The upper cover display end and the host system end are not automatically affected by the lower transmission load and are sensitively closed automatically, so that the user feels a clear sense of closure.

3. The first friction plate 32 and the third friction plate 43 abut against the opposite ends of the first connecting member 31 to generate a frictional force therebetween, and the second friction plate 33 and the fourth friction plate 44 abut the top The opposite ends of the first connecting member 31 generate friction therebetween, and the first positioning plate 51 and the second positioning plate 61 abut against the opposite ends of the fifth friction plate 64 and the sixth friction plate 65 to generate therebetween Friction. Therefore, the friction force is greater than the weight of the electronic device, so that the first shaft 10 and the second shaft 20 cannot rotate relative to each other, and the user needs to additionally apply force to the electronic device to drive the first shaft 10 and the second. The shaft 20 is relatively rotated.

4. When the dual-axis pivot is changed from the pivoting position to the latching position, the first latching member 52 and the second latching member 53 are elastically pushed against the first elastic group 40 to engage the latching member. The first positioning plate 51, and the third latching member 62 and the fourth latching member 63 are elastically pushed against the second elastic group 70 to latch the second positioning plate 61, thereby increasing the clamping force, thereby The force of the automatic closing of the display end of the electronic device and the system end of the host system is increased, and the sealing feeling is more obvious.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and the numerical values are changed or the equivalent elements are replaced, or the equivalent range of the patent application scope of the present invention is changed. And modifications should still fall within the scope of the invention patent.
