The bottom bar 30 is provided below the upper cover 20 and is horizontally displaceable with respect to the upper cover 20. The left end of the bottom bar 30 has a first pivot 31, the right end of the bottom bar 30 has a second pivot 32, and the center of the bottom bar 30 has a third slide groove 33.
The top end of the left connecting rod 40 has a first sliding shaft 41, the first sliding shaft 41 is inserted into the first sliding slot 22 of the two ribs 21 of the upper cover 20, and the separation is prevented by the combination of a bolt 44 and a nut 45, so that the top end of the left connecting rod 40 can be horizontally displaced relative to the upper cover 20. The bottom end of the left connecting rod 40 is provided with a second sliding shaft 42, and the second sliding shaft 42 is arranged in the third sliding slot 33 of the bottom rod 30 in a penetrating manner, so that the left connecting rod 40 can pivot relative to the bottom rod 30 and can push the bottom rod 30 to move horizontally to the right when the second sliding shaft 42 abuts against the right end of the third sliding slot 33. In addition, the left link 40 has a third pivot 43 at the center.
The top end of the right link 50 has a fourth pivot 51, the fourth pivot 51 is pivotally connected to the locking slot 24 of the two ribs 21 of the upper cover 20, the bottom end of the right link 50 has a first pivot slot 52, and the first pivot slot 52 is pivotally connected to the second pivot 32 of the bottom bar 30, so that the right link 50 can pivot relative to the bottom bar 30 and push the bottom bar 30 to move horizontally to the right when being pressed down by the upper cover 20.
The output rod 60 has a third slide shaft 61, the third slide shaft 61 is inserted into the first slide grooves 22 of the two ribs 21 of the upper cover 20 and is prevented from being disengaged by a combination of one bolt 62 and one nut 63, the right end of the output rod 60 has a fourth slide shaft 64, the fourth slide shaft 64 is inserted into the second slide grooves 23 of the two ribs 21 of the upper cover 20 and is prevented from being disengaged by a combination of one bolt 65 and one nut 66, and the output rod 60 is horizontally displaceable relative to the upper cover 20. As shown in fig. 3 to 5, the top surface of the output rod 60 has a second tooth portion 67 near the fourth sliding shaft 64, and the second tooth portion 67 is vertically opposed to the first tooth portion 25 of the upper cover 20.
The auxiliary link 70 has a ring portion 71, an upper link portion 72 connected to the ring portion 71, and a lower link portion 74 connected to the ring portion 71, the ring portion 71 is pivoted to the third pivot 43 of the left link 40, the top end of the upper link portion 72 has a fifth sliding shaft 73, the fifth sliding shaft 73 is inserted into the second sliding slot 23 of the two rib plates 21 of the upper cover 20, the bottom end of the lower link portion 74 has a second pivot slot 75, the second pivot slot 75 is pivotally connected to the first pivot 31 of the bottom bar 30, so that the auxiliary link 70 is pivoted to the left link 40 in a crossing manner and can be pushed by the bottom bar 30 to horizontally displace. In addition, the upper rod part 72 and the lower rod part 74 are not parallel to each other, so that an obtuse angle θ facing the upper cover 20 is formed between the upper rod part 72 and the lower rod part 74, and the auxiliary link 70 can be pushed by the bottom rod 30 to be horizontally displaced by the design of the obtuse angle θ, so that the driving gear 80 rotates.
The gear 80 is mounted to the fifth sliding shaft 73 of the auxiliary link 70 by a bolt 81 and a nut 82, and is engaged with the first teeth 25 of the upper cover 20 and the second teeth 67 (shown in fig. 4) of the output rod 60, so that the gear 80 can push the output rod 60 by engaging with the output rod 60 when the auxiliary link 70 is driven.
As described above, when the upper cap 20 is pressed down by a force, as shown in fig. 4 and 5, the left link 40 and the right link 50 are simultaneously lowered to push the bottom rod 30 to advance rightward by one stroke Δ X (as shown in fig. 6A and 6B), and then the top end of the auxiliary link 70 is pushed to advance rightward by the same stroke Δ X while the bottom rod 30 advances rightward, and then the gear 80 rotates by engaging with the second tooth portion 67 of the output rod 60 while following the auxiliary link 70, so that the output rod 60 advances rightward by one enlarged stroke Δ Y (as shown in fig. 6A and 6B) under the push of the gear 80, thereby increasing the horizontal movement distance of the output rod 60 without increasing the pressing stroke of the upper cap 20, so that a connector (not shown) engaged with the output rod 60 can obtain a large horizontal movement distance, so as to realize the effect of light and thin structure.
On the other hand, the link mechanism provided by the present invention keeps the upper lid 20 horizontal during the pressing process, thereby ensuring that the portable electronic device (such as a notebook computer, not shown) received by the upper lid 20 does not tilt until the connection with the connector is completed.
