The applicant has first described herein that the drawings of the present invention are simply schematic illustrations, not drawn to actual dimensions, and that directional terms in the drawings, including the examples described below and the claims, are used as references to directional terms in the drawings, but such terms as "upper", "lower", "inner", "outer", "top", "bottom", "left", "right", "front", "rear", etc., are used as references to normal use directions, and are not intended to limit the scope of claims. Next, in the embodiments to be described below and the drawings, the same element numerals denote the same or similar elements or structural features thereof. In addition, it should be understood that, although terms such as "first," "second," "third," "fourth," "fifth," etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used primarily to distinguish one element from another element.
Referring to fig. 1 to 3, the link mechanism 10 of the present invention includes an upper cover 20, a bottom bar 30, a left link 40, a right link 50, an output bar 60, an auxiliary link 70, and a gear 80.
The top surface of the upper cover 20 is used for receiving a portable electronic device (such as a notebook computer, not shown). As shown in fig. 2 and 3, the bottom surface of the upper cover 20 has two parallel ribs 21 and a first tooth 25 between the two ribs 21, wherein each rib 21 has a first chute 22, a second chute 23 and a slot 24 in this order from left to right.
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 chute 33.
The top end of the left link 40 has a first sliding shaft 41, and the first sliding shaft 41 is inserted into the first sliding grooves 22 of the two rib plates 21 of the upper cover 20 and is prevented from being separated by a combination of a bolt 44 and a nut 45, so that the top end of the left link 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 groove 33 of the bottom rod 30 in a penetrating way, so that the left connecting rod 40 can pivot relative to the bottom rod 30 and can push the bottom rod 30 to horizontally move to the right when the second sliding shaft 42 abuts against the right end of the third sliding groove 33. In addition, the left link 40 has a third pivot 43 at the center thereof.
The top end of the right link 50 has a fourth pivot 51, the fourth pivot 51 is pivotally clamped in the clamping grooves 24 of the two ribs 21 of the upper cover 20, the bottom end of the right link 50 has a first pivot groove 52, and the first pivot groove 52 is pivotally clamped to the second pivot 32 of the bottom rod 30, so that the right link 50 can pivot relative to the bottom rod 30 and push the bottom rod 30 to move horizontally right when the upper cover 20 is pressed down.
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 separated by a combination of a bolt 62 and a 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 separated by a combination of a bolt 65 and a nut 66, so that the output rod 60 can horizontally move relative to the upper cover 20. Further, as shown in fig. 3 to 5, the top surface of the output lever 60 has a second tooth portion 67 near the fourth slide shaft 64, the second tooth portion 67 being opposite to the first tooth portion 25 of the upper cover 20 in the up-down direction.
The auxiliary link 70 has a ring portion 71, an upper rod portion 72 connected to the ring portion 71, and a lower rod portion 74 connected to the ring portion 71, the ring portion 71 is pivotally disposed on the third pivot 43 of the left link 40, the top end of the upper rod portion 72 has a fifth sliding shaft 73, the fifth sliding shaft 73 is disposed in the second sliding groove 23 of the two ribs 21 of the upper cover 20 in a penetrating manner, the bottom end of the lower rod portion 74 has a second pivot groove 75, and the second pivot groove 75 is pivotally engaged with the first pivot 31 of the bottom rod 30, so that the auxiliary link 70 is pivotally disposed with the left link 40 in a crossing manner and can be pushed by the bottom rod 30 to horizontally displace. In addition, the upper and lower rod portions 72 and 74 are not parallel to each other, so that an obtuse angle θ toward the upper cover 20 is formed between the upper and lower rod portions 72 and 74, and the auxiliary link 70 can be pushed by the bottom rod 30 to generate horizontal displacement by the design of the obtuse angle θ, thereby driving the gear 80 to rotate.
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 simultaneously engages with the first tooth portion 25 of the upper cover 20 and the second tooth portion 67 (shown in fig. 4) of the output rod 60, so that the gear 80 can push the output rod 60 through the engagement relationship with the output rod 60 when driven by the auxiliary link 70.
As can be seen from the above, when the upper cover 20 is pressed down, as shown in fig. 4 and 5, the left link 40 and the right link 50 simultaneously descend and push the bottom rod 30 to move rightward by one stroke Δx (as shown in fig. 6A and 6B), then the top end of the auxiliary link 70 is pushed to move rightward by the same stroke Δx during the rightward movement of the bottom rod 30, and then the gear 80 rotates along with the auxiliary link 70 while moving forward by the meshing relationship with the second tooth 67 of the output rod 60, so that the output rod 60 moves rightward by one amplified stroke Δy (as shown in fig. 6A and 6B) under the pushing of the gear 80, and thus the horizontal movement distance of the output rod 60 can be increased without increasing the downward movement of the upper cover 20, so that the connector (not shown in the drawings) matched with the output rod 60 can obtain a larger horizontal movement distance, thereby realizing the light and thin structure.
On the other hand, by the link mechanism provided by the invention, the upper cover 20 is kept horizontal in the pressing process, so that the situation that the portable electronic device (such as a notebook computer, not shown) carried by the upper cover 20 is not inclined is ensured until the connection with the connector is completed.
