An angle-adjustable concealed hinge

Abstract

This invention relates to the field of hinge technology, specifically to an adjustable-angle concealed hinge. It employs a first hinge plate, a second hinge plate, an eccentric connector, and a tension adjustment mechanism. The first hinge portion is rotatably connected to the outer wall of the eccentric connector, and the second hinge portion is rotatably connected to the eccentric connector along a semi-circular clearance groove. The first hinge portion is hinged to the second hinge portion via the eccentric connector, avoiding the problem of a clearly visible concentric shaft hinge. The first hinge plate is connected to the second hinge plate via the tension adjustment mechanism, which adjusts the torque of the first and second hinge plates.

The first leaf extends with a first hinge portion rotatably connected to the outer side wall of the eccentric connector. The second leaf extends with a second hinge portion. A semi-circular clearance groove is provided in the middle of the eccentric connector. The second hinge portion is rotatably connected to the eccentric connector along the semi-circular clearance groove. The first hinge portion is hinged to the second hinge portion through the eccentric connector. The first leaf is connected to the second leaf through the tension adjusting member, which is used to adjust the torque of the first and second leaf.

[0006] Preferably, the outer side wall of the first hinge portion has a first pivot protruding from it, and the outer side wall of the second leaf has a second pivot protruding from it. The first pivot is connected to the second pivot through the tension adjustment member.

The clamping head has a threaded through hole that is threaded to engage with the adjustment bolt. The other end of the hinge tension arm has an elongated through hole through which the second rotating shaft passes.

[0008] Preferably, the two outer sidewalls of the eccentric connector are respectively provided with a first arc-shaped guide groove and a second arc-shaped guide groove, and the two inner sidewalls of the first hinge part are respectively provided with a first guide block and a second guide block. The first guide block is slidably connected to the first arc-shaped guide groove, and the second guide block is slidably connected to the second arc-shaped guide groove.

[0009] Preferably, the first guide block has a first limiting hook protruding from the end away from the first leaf, and the first arc-shaped guide groove has a second limiting hook protruding from the end near the first leaf, which cooperates with the first limiting hook; the second guide block has a third limiting hook protruding from the end away from the first leaf, and the second arc-shaped guide groove has a fourth limiting hook protruding from the end near the first leaf, which cooperates with the third limiting hook; when the concealed hinge is rotated to 0°, the first limiting hook engages with the second limiting hook, and the third limiting hook engages with the fourth limiting hook.

[0010] Preferably, the outer wall of the second hinge portion is provided with a third arc-shaped guide groove, and the semi-circular clearance groove protrudes from the inner wall of the second leaf with a third guide block that is slidably connected to the third arc-shaped guide groove; when the hidden hinge is rotated to 0°, the third guide block abuts against the end of the third arc-shaped guide groove away from the second leaf.

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] like Figure 1-5 As shown, an adjustable-angle concealed hinge includes a first leaf 1, a second leaf 2, an eccentric connector 3, and a tension adjusting member 19. The first leaf 1 extends with a first hinge portion 4 that is rotatably connected to the outer side wall of the eccentric connector 3. The second leaf 2 extends with a second hinge portion 5. A semi-circular relief groove 6 is provided in the middle of the eccentric connector 3. The second hinge portion 5 is rotatably connected to the eccentric connector 3 along the semi-circular relief groove 6. The first hinge portion 4 is hinged to the second hinge portion 5 through the eccentric connector 3. The first leaf 1 is connected to the second leaf 2 through the tension adjusting member 19, which is used to adjust the torque of the first leaf 1 and the second leaf 2.

[0021] This adjustable-angle concealed hinge employs a first hinge plate 1, a second hinge plate 2, an eccentric connector 3, and a tension adjustment component 19. The first hinge portion 4 is rotatably connected to the outer wall of the eccentric connector 3, and the second hinge portion 5 is rotatably connected to the eccentric connector 3 along a semi-circular clearance groove 6. The first hinge portion 4 is hinged to the second hinge portion 5 through the eccentric connector 3, avoiding the problem of a clearly visible concentric shaft hinge, and allowing for 0°-180° rotation. The first hinge plate 1 is connected to the second hinge plate 2 through the tension adjustment component 19. The tension adjustment component 19 adjusts the torque of the first hinge plate 1 and the second hinge plate 2, allowing the concealed hinge to rotate to any angle between 0°-180° under appropriate external force, and then stop rotating naturally when the external force is released. This enables multi-angle adjustment and is suitable for use with laptops and other electronic devices connected between different components, allowing users to rotate the different components relative to each other using the concealed hinge.

[0022] In this embodiment, a first pivot 20 protrudes from the outer side wall of the first hinge portion 4, and a second pivot 21 protrudes from the outer side wall of the second leaf 2. The first pivot 20 is connected to the second pivot 21 through the tension adjustment member 19.

[0023] By adopting the above technical solution, the tension adjustment component 19 adjusts the tension of the first rotating shaft 20 and the second rotating shaft 21, thereby adjusting the torque of the first rotating shaft 20 and the second rotating shaft 21, so as to prevent the first leaf 1 and the second leaf 2 from being easily rotated by force and unable to rotate to any angle between 0° and 180° for use.

[0024] In this embodiment, the tension adjustment component 19 includes a hinge tension arm 191 and an adjustment bolt 192. One end of the hinge tension arm 191 is a clamping head for clamping the first rotating shaft 20. The clamping head has a threaded through hole 22 that is threadedly engaged with the adjustment bolt 192. The other end of the hinge tension arm 191 has an elongated through hole 23, through which the second rotating shaft 21 passes.

[0025] By adopting the above technical solution, the tightness of the bolt 192 being screwed into the threaded through hole 22 of the clamping head is adjusted, thereby adjusting the clamping degree of the clamping head clamping the first rotating shaft 20, and the second rotating shaft 21 passing through the elongated through hole 23. This adjusts the torque between the first rotating shaft 20 and the clamping head when the first sheet 1 and the second sheet 2 are flipped, so as to enable the first sheet 1 and the second sheet 2 to be flipped to a specific angle for use.

[0026] In this embodiment, the two outer sidewalls of the eccentric connector 3 are respectively provided with a first arc-shaped guide groove 7 and a second arc-shaped guide groove 8, and the two inner sidewalls of the first hinge part 4 are respectively provided with a first guide block 9 and a second guide block 10. The first guide block 9 is slidably connected to the first arc-shaped guide groove 7, and the second guide block 10 is slidably connected to the second arc-shaped guide groove 8.

[0027] Using the above technical solution, the first guide block 9 is slidably connected to the first arc-shaped guide groove 7, and the second guide block 10 is slidably connected to the second arc-shaped guide groove 8, thereby realizing the rotational connection between the first hinge part 4 and the outer wall of the eccentric connector 3 to flip the first leaf 1.

[0028] In this embodiment, the first guide block 9 has a first limiting hook 11 protruding from the end away from the first leaf 1, and the first arc-shaped guide groove 7 has a second limiting hook 12 protruding from the end near the first leaf 1, which cooperates with the first limiting hook 11; the second guide block 10 has a third limiting hook 13 protruding from the end away from the first leaf 1, and the second arc-shaped guide groove 8 has a fourth limiting hook 14 protruding from the end near the first leaf 1, which cooperates with the third limiting hook 13; when the hidden hinge is rotated to 0°, the first limiting hook 11 and the second limiting hook 12 are engaged, and the third limiting hook 13 and the fourth limiting hook 14 are engaged.

[0029] Using the above technical solution, when the hidden hinge is flipped to 0°, the first limiting hook 11 and the second limiting hook 12 are engaged, and the third limiting hook 13 and the fourth limiting hook 14 are engaged. When applied to a laptop, this helps to avoid damage to the laptop caused by excessive pressure and collision when the laptop is closed.

[0030] In this embodiment, a third arc-shaped guide groove 15 is provided on the outer side wall of the second hinge portion 5, and a third guide block 16 protrudes from the inner side wall of the semi-circular clearance groove 6 near the second leaf 2 and is slidably connected to the third arc-shaped guide groove 15; when the hidden hinge is flipped to 0°, the third guide block 16 abuts against the end of the third arc-shaped guide groove 15 away from the second leaf 2.

[0031] Using the above technical solution, the third guide block 16 is slidably connected to the third arc-shaped guide groove 15, thereby realizing the rotational connection of the second hinge part 5 along the semi-circular clearance groove 6 and the eccentric connector 3 to flip the second page 2. During the flipping and merging process of the hidden hinge, when the first page 1 and the second page 2 are at a 90° angle, the third guide block 16 abuts against the end of the third arc-shaped guide groove 15 away from the second page 2, and continues to flip and merge, which can cause the second page 2 to drive the eccentric connector 3 to flip, so that the second page 2 can move closer to the first page 1.

[0032] In this embodiment, the first page 1 has a first mounting hole 17, and the second page 2 has a second mounting hole 18.

[0033] Using the above technical solution, the first mounting hole 17 and the second mounting hole 18 facilitate application installation between different bodies of electronic devices such as laptops. For example, the first sheet 1 and the second sheet 2 are installed in a laptop to connect the display screen part and the body part of the laptop, respectively.

[0034] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.
