Description

Double axis lifting mechanism

This invention relates to a dual-axis lifting mechanism, particularly a dual-axis lifting mechanism that can be applied to foldable electronic products such as laptops, tablets or mobile phones.

With the rapid development of electronic technology, various electronic products are widely used in daily life. In order to facilitate users to carry them to different occasions, many foldable electronic products have been launched on the market, such as laptops, tablets and mobile phones, etc., so that users can fold them when they are not needed to reduce the space they occupy, making them convenient to carry.

However, most common foldable electronic products use a hinge to achieve the function of pivoting, so the angle that can be flipped is limited, and after flipping to a certain angle, it can only be placed flat on the desktop for use, which not only affects the heat dissipation performance of the foldable electronic product, but also makes it inconvenient for users to operate due to the angle problem. Therefore, how to increase the flipping angle of the foldable electronic product and allow the foldable electronic product to be tilted and placed on the desktop for use after flipping to a certain angle is a shortcoming that needs to be improved urgently.

In view of this, the author of this invention has focused on the above-mentioned shortcomings of the existing technology, and has devoted himself to research and applied theory to try his best to solve the above-mentioned problems, which has become the goal of the author's improvement.

The detailed description and technical content of this creation will be explained below with the help of diagrams. However, the attached diagrams are for illustrative purposes only and are not used to limit this creation.

The invention provides a dual-axis lifting mechanism that can be applied to foldable electronic products such as laptops, tablets or mobile phones. Referring to FIGS. 1 to 4 , the dual-axis lifting mechanism of the invention mainly includes a coupling assembly 10 , a fixed bracket 20 , a shaft sleeve 30 , a flip bracket 40 , a follower 50 , a support member 60 and a linkage mechanism 70 .

The coupling assembly 10 has a first pivot groove and a second pivot groove arranged at intervals. Specifically, the coupling assembly 10 in this embodiment includes a limiting base 11, a first stop block 12, a second stop block 13, a locking block 14, a locking stop block 15, a first sliding block 16, a second sliding block 17 and a fixed seat 18, but the structure and components of the coupling assembly 10 of the present invention are not limited thereto, and a person with ordinary knowledge in the art should be able to increase, decrease and adjust accordingly according to needs. The first hinge groove is formed by the limiting base 11, the first stop block 12, the second stop block 13 and the fixing base 18, and the second hinge groove is formed by the limiting base 11, the locking block 14, the locking stop block 15 and the fixing base 18.

Please refer to FIG. 1 , the main body of the fixed bracket 20 is generally plate-shaped, and has a first pivot 21, a slide rail 22, and a slide groove 23. In this embodiment, the fixed bracket 20 can be installed with an operating keyboard, a touch panel, etc. of a foldable electronic product, but is not limited thereto. The first pivot 21 extends from the right side of the main body of the fixed bracket 20 along a longitudinal direction D, and the first pivot 21 is inserted into the first pivot groove of the coupling assembly 10. The slide rail 22 extends from the right side of the main body of the fixed bracket 20 along the longitudinal direction D and is parallel to the first pivot 21. The slide groove 23 penetrates the fixed bracket 20 in the vertical direction. More specifically, the first pivot 21 and the slide slot 23 are located at opposite front and rear sides of the fixed bracket 20 , and the slide rail 22 is located between the first pivot 21 and the slide slot 23 .

Referring again to FIG. 1 , the sleeve 30 is a hollow cylindrical body. The sleeve 30 is sleeved on the first pivot 21 , and the end of the sleeve 30 is engaged with the coupling assembly 10 and can be driven to rotate by the coupling assembly 10 .

Please refer to FIG. 1 and FIG. 3 , the main body of the flip bracket 40 is generally plate-shaped and has a second pivot 41. The second pivot 41 extends from the right side of the main body of the flip bracket 40 along the longitudinal direction D and is parallel to the first pivot 21, and the second pivot 41 is inserted into the second pivot slot of the coupling assembly 10. In this embodiment, the flip bracket 40 can be installed with a screen of a foldable electronic product, but is not limited to this. The flip bracket 40 can be flipped and switched between a closed position S1, a first flip position S2, a second flip position S3 and a fully flip position S4 relative to the fixed bracket 20 in a clockwise direction or a counterclockwise direction opposite to the clockwise direction through the coupling assembly 10.

Specifically, the closed position S1 in this embodiment refers to the flip bracket 40 being located parallel to the fixed bracket 20, and the foldable electronic product is in a folded state, that is, the screen is covered with the keyboard or touch panel. The first flip position S2 refers to the flip bracket 40 being flipped 130° relative to the fixed bracket 20, and the foldable electronic product is in a lifted state, that is, the user can see the screen and the keyboard or touch panel at the same time for operation. The second flip position S3 refers to the flip bracket 40 being flipped 300° relative to the fixed bracket 20, and the foldable electronic product is in an over-state and is not suitable for the operator to operate. The fully flipped position S4 means that the flip bracket 40 is located parallel to the bottom of the fixed bracket 20. At this time, the foldable electronic product corresponds to a fully flipped state, that is, the screen is located on the opposite side of the keyboard or touch panel so that the user can view the screen without operating the keyboard or touch panel. Therefore, in the entire flipping process, the first flipping position S2 and the second flipping position S3 are located between the closed position S1 and the fully flipped position S4, the first flipping position S2 is located between the closed position S1 and the second flipping position S3, and the second flipping position S3 is located between the first flipping position S2 and the fully flipped position S4. Therefore, if the flip bracket 40 is flipped from the closed position S1 in a clockwise direction, it will flip through the first flip position S2, the second flip position S3 and finally to the fully flip position S4. If the flip bracket 40 is flipped from the fully flip position S4 in a counterclockwise direction, it will flip through the second flip position S3, the first flip position S2 and finally to the closed position S1.

Please refer to FIG. 1 and FIG. 2 , the follower 50 is movably disposed on the fixed bracket 20 along the longitudinal direction D, and the follower 50 is sleeved on the shaft sleeve 30 and abuts against the shaft sleeve 30. Specifically, the follower 50 includes a driven sleeve 51 and a body 52. The driven sleeve 51 is connected to one side of the body 52 and sleeved on the shaft sleeve 30. The body 52 is slidably sleeved on the slide rail 22. In this embodiment, the driven sleeve 51 is generally sleeve-shaped to be sleeved on the shaft sleeve 30 for sliding, and one end of the driven sleeve 51 abuts against a portion of the outer edge of the shaft sleeve 30, and the body 52 has a through groove 521 for the slide rail 22 to slide therein, but the present invention is not limited thereto.

Referring again to FIG. 1 and FIG. 2 , the support member 60 is slidably connected to the fixed bracket 20. Specifically, the support member 60 includes a foot 61 and a slider 62. The slider 62 extends upward from the top of the foot 61 toward the fixed bracket 20, and the slider 62 is slidably connected to the slide groove 23 of the fixed bracket 20 and can slide vertically (i.e., the up and down direction in FIG. 1 ) relative to the fixed bracket 20.

As shown in FIG. 1 , FIG. 2 and FIG. 4 , the linkage mechanism 70 is connected to the follower 50 and the support member 60. Specifically, the linkage mechanism 70 includes a follower rod 71, a fixed rod 72 and a movable rod 73. One end of the fixed rod 72 is pivoted on the fixed bracket 20, and the other end of the fixed rod 72 is sandwiched and pivoted between the follower rod 71 and the movable rod 73. One end of the follower rod 71 away from the fixed rod 72 is pivoted on the follower 50, and one end of the movable rod 73 away from the fixed rod 72 is pivoted on the support member 60. Thus, when the follower 50 slides back and forth on the sleeve 30 along the longitudinal direction D, the follower rod 71 is pulled, thereby driving the fixed rod 72 and the movable rod 73 to move, thereby causing the support member 60 to slide vertically relative to the fixed bracket 20.

Specifically, referring to FIG. 3 again, the first stopper 12, the second stopper 13, the engaging block 14 and the engaging stopper 15 are all roughly in the shape of a round pancake, and the first sliding block 16 and the second sliding block 17 are all roughly in the shape of an elliptical pancake. Part of the side edges of the first stopper 12 and the second stopper 13 have a groove parallel to their peripheries, the side edges of the engaging block 14 and the engaging stopper 15 have an arc-shaped groove, and the end surface of the engaging stopper 15 facing the fixing seat 18 has a C-shaped groove.

The first stop block 12 and the second stop block 13 are sleeved and fixed on the first pivot 21, and the first stop block 12 and the second stop block 13 are both sandwiched between the limit base 11 and the fixed base 18. The clamping block 14 and the clamping stop block 15 are sleeved and fixed on the second pivot 41, and the clamping block 14 and the clamping stop block 15 are both sandwiched between the limit base 11 and the fixed base 18. The first sliding clamping block 16 can slide vertically upward and downward between the first stop block 12 and the clamping block 14, and the second sliding clamping block 17 can slide vertically upward and downward between the second stop block 13 and the clamping stop block 15. The first sliding block 16 and the second sliding block 17 are both sandwiched between the limiting base 11 and the fixing base 18. In this embodiment, the limiting base 11 and the fixing base 18 both have a limiting groove 101 extending vertically upward and downward, and the first sliding block 16 and the second sliding block 17 respectively correspond to the limiting base 11 and the fixing base 18 and protrude a limiting block 102, so that each limiting block 102 is clamped in each limiting groove 101 to limit the first sliding block 16 and the second sliding block 17 from sliding vertically, and the side surfaces of the first sliding block 16 and the second sliding block 17 that are in contact with each other are also respectively provided with a positioning block 161 and a positioning groove 171 that fit together for mutual positioning, but the invention is not limited to the above. The fixing seat 18 has a protrusion 181 . The protrusion 181 is disposed on a side surface of the fixing seat 18 facing the locking stop block 15 and is configured corresponding to the locking stop block 15 .

Please refer to FIGS. 4 to 7 , when the flip bracket 40 is in the closed position S1, the coupling assembly 10 blocks the first pivot 21 in the counterclockwise direction and blocks the second pivot 41 in the clockwise direction. Specifically, the first stopper 12 abuts against one end of the first sliding block 16 so that the other end of the first sliding block 16 is engaged in the arc-shaped groove of the engaging block 14, one end of the second sliding block 17 blocks one end of the groove of the second stopper 13 in the counterclockwise direction to block the first pivot 21, and the protrusion 181 blocks one end of the C-shaped groove of the engaging stopper 15 in the clockwise direction to block the second pivot 41. Thus, when the flip bracket 40 is at the closed position S1 , the coupling assembly 10 and the flip bracket 40 cannot rotate counterclockwise relative to the fixed bracket 20 , thereby avoiding interference between the flip bracket 40 and the fixed bracket 20 .

Please refer to Figures 8 to 11. When the flip bracket 40 flips from the closed position S1 to the first flip position S2, the coupling assembly 10 blocks the first pivot 21 and the second pivot 41 in the clockwise direction, and the coupling assembly 10 pushes the follower 50 in the reverse direction along the longitudinal direction D so that the linkage mechanism 70 drives the support member 60 away from the fixed bracket 20 to tilt and support the fixed bracket 20. Specifically, the first stop block 12 abuts against one end of the first sliding block 16 so that the other end of the first sliding block 16 is engaged in the arc-shaped groove of the engaging block 14, and one end of the second sliding block 17 stops one end of the groove of the second stop block 13 along the clockwise direction to stop the first pivot 21, and the protrusion 181 stops one end of the C-shaped groove of the engaging stop block 15 along the clockwise direction to stop the second pivot 41. Thus, when the flip bracket 40 is at the first flip position S2, the coupling assembly 10 can no longer rotate in the clockwise direction relative to the first pivot 21, and the flip bracket 40 can only rotate in the clockwise direction relative to the coupling assembly 10. Since the support member 60 props up the fixed bracket 20, it is beneficial to the heat dissipation of the foldable electronic product and the viewing and use of the user.

Please refer to FIG. 12 . When the flip bracket 40 flips from the first flip position S2 to the second flip position S3 , the coupling assembly 10 blocks the first pivot 21 in the clockwise direction and blocks the second pivot 41 in the counterclockwise direction. Specifically, the second stopper 13 still abuts against one end of the second sliding block 17 so that the other end of the second sliding block 17 is engaged in the arc-shaped groove of the engaging stopper 15, and one end of the second sliding block 17 blocks one end of the groove of the second stopper 13 in the clockwise direction to block the first pivot 21, and the protrusion 181 blocks one end of the C-shaped groove of the engaging stopper 15 in the counterclockwise direction to block the second pivot 41. Thus, the flip bracket 40 cannot rotate relative to the coupling assembly 10 in the clockwise direction when it is in the second flip position S3.

Please refer to Figures 13 to 16. When the flip bracket 40 flips from the second flip position S3 to the fully flipped position S4, the coupling assembly 10 blocks the first pivot 21 in the clockwise direction and the second pivot 41 in the counterclockwise direction. The sleeve 30 pushes the follower 50 in the longitudinal direction D so that the linkage mechanism 70 drives the support member 60 to retract toward the fixed bracket 20. Specifically, the locking block 14 abuts against one end of the first sliding block 16 so that the other end of the first sliding block 16 stops one end of the groove of the first stop block 12 in the clockwise direction to stop the first pivot 21, the second stop block 13 abuts against one end of the second sliding block 17 so that the other end of the second sliding block 17 is engaged in the arc-shaped groove of the locking stop block 15, and the protrusion 181 stops one end of the C-shaped groove of the locking stop block 15 in the counterclockwise direction to stop the second pivot 41. Thus, when the flip bracket 40 is in the fully flipped position S4, the coupling assembly 10 and the flip bracket 40 cannot rotate counterclockwise relative to the fixed bracket 20, thereby avoiding interference between the flip bracket 40 and the fixed bracket 20, and the support member 60 also retracts toward the fixed bracket 20 without affecting the flip bracket 40 and causing interference.

To further explain, referring to FIG. 1 again, the limiting base 11 of the coupling assembly 10 has a pair of actuating portions 111, the sleeve 30 has a pair of second actuating inclined surfaces 31, and the driven sleeve 51 has a pair of first driven portions 511 and a second driven portion 512. The actuating portions 111 are disposed opposite to each other and sleeved with the sleeve 30. Each actuating portion 111 has a pair of opposite first actuating inclined surfaces 1111. The second actuating inclined surfaces 31 are disposed opposite to each other and are located at one end of the sleeve 30 away from the coupling assembly 10.

Each first follower portion 511 is disposed opposite to each other and is located on the side of the driven sleeve 51 facing the coupling assembly 10. Each first follower portion 511 has a pair of opposite first follower inclined surfaces 5111. As shown in FIG. 7 and FIG. 15, when the flip bracket 40 is located at the closed position S1 or the fully flipped position S4, each actuating portion 111 is alternately disposed with each first follower portion 511, so that each first actuating inclined surface 1111 is respectively attached to each first follower inclined surface 5111. In this way, the follower 50 can slide along the longitudinal direction D and guide the limiting base 11 to rotate the coupling assembly 10.

The second driven portion 512 is located at a side of the driven sleeve 51 away from the coupling assembly 10, and the second driven portion 512 has a pair of opposite second driven inclined surfaces 5121. As shown in FIG10 , when the flip bracket 40 is located at the first flip position S2 or the second flip position S3, one of the second actuating inclined surfaces 31 is in contact with one of the second driven inclined surfaces 5121. In this way, the driven member 50 can slide in the reverse direction along the longitudinal direction D and guide the sleeve 30 to rotate.

Referring again to FIG. 1 , FIG. 7 , FIG. 10 and FIG. 15 , the dual-axis lifting mechanism of the present invention further includes a tension spring 80 . One end of the tension spring 80 is connected to the fixed bracket 20 , and the other end of the tension spring 80 is connected to the follower 50 . Thus, in FIG. 7 and FIG. 15 , since each second follower portion 512 of the follower 50 is coupled to the actuating portion 111 of the coupling assembly 10, the tension spring 80 is stretched and deformed to form an elastic force acting in the reverse direction. Therefore, when the flip bracket 40 flips to the first flip position S2, in addition to relying on the coupling assembly 10 to push the follower 50 in the reverse direction along the longitudinal direction D, the tension spring 80 can also pull the follower 50 to move in the reverse direction along the longitudinal direction D through its elastic force so that the linkage mechanism 70 drives the support member 60 away from the fixed bracket 20, thereby reducing the pressure of the coupling assembly 10 and improving the sliding stability of the follower 50.

The double-axis lifting mechanism of the present invention is provided with the first pivot 21 of the fixed bracket 20 and the second pivot 41 of the flip bracket 40 respectively through the first pivot groove and the second pivot groove of the coupling assembly 10, so that the flip bracket 40 can flip one circle relative to the fixed bracket 20 in multiple stages, and during the flipping process, the follower 50 drives the linkage mechanism 70 to operate, so that the support member 60 props up the fixed bracket 20 to facilitate the operation and user operation, and the support member 60 can be retracted toward the fixed bracket 20 when flipping one circle to avoid interference with the flip bracket 40.
