DESCRIPTION OF EMBODIMENTS
Embodiments of the present disclosure are clearly and completely described below. Examples of the embodiments are shown in the accompanying drawings, in which same or like references indicate same or similar elements or elements having same or like functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present disclosure and not used to limit the present disclosure.
The present disclosure relates to a hinge damping mounting structure, including a long arm 100, a first connecting arm 200, a second connecting arm 300, a pocket 400, a mobile rack 500 and an oil cylinder 600.
Referring to FIG. 1 and FIG. 2, in a direction of FIG. 1 and FIG. 2, a rear part of the long arm 100 is connected to a main body of a hinge. A first rotating shaft 110 and a second rotating shaft 120 are provided at a front end of the long arm 100. The first rotating shaft 110 and the second rotating shaft 120 are parallel to each other. One end of the first connecting arm 200 is hinged to the first rotating shaft 110, and the other end of the first connecting arm 200 is hinged to the pocket 400. One end of the second connecting arm 300 is hinged to the second rotating shaft 120, and the other end of the second connecting arm 300 is hinged to the pocket 400. The mobile rack 500 is located between the long arm 100 and the second connecting arm 300. In the direction of FIG. 1 and FIG. 2, the mobile rack 500 is located on a lower side of the long arm 100 and on an upper side of the second connecting arm 300. The mobile rack 500 includes a first direction and a second direction perpendicular to each other. In the direction of FIG. 1 and FIG. 2, the first direction is an up-down vertical direction, the second direction is a front-rear lateral direction, and the second direction is also a length direction of the long arm 100. A relative upward movement of the mobile rack 500 is limited by an inner wall of the long arm 100, a bottom of the mobile rack 500 is abutted against the second rotating shaft 120, and a downward movement of the mobile rack 500 is limited by the second rotating shaft 120, thereby limiting the mobile rack 500 to move up and down in the first direction relative to the long arm 100. The mobile rack 500 is translated forward and backward along the length direction of the long arm 100 in the second direction. The oil cylinder 600 is mounted on the second connecting arm 300. A telescopic shaft 610 of the oil cylinder 600 is connected backwards on a rear wall of the mobile rack 500, an end (front end) of a cylinder shell 620 of the oil cylinder 600 is supported by the first rotating shaft 110, that is, the end of the cylinder shell 620 of the oil cylinder 600 is directly or indirectly abutted against the first rotating shaft 110.
During use, the pocket 400 is flipped up and down relative to the long arm 100 through the first connecting arm 200 and the second connecting arm 300. Referring to FIG. 2, in a direction shown in FIG. 2, when the pocket 400 is flipped upward, the second connecting arm 300 is rotated clockwise around the second rotating shaft 120. When the second connecting arm 300 is rotated clockwise, the mobile rack 500 is pulled by the second connecting arm 300 to translate forward toward the first rotating shaft 110. When the mobile rack 500 is translated forward, the oil cylinder 600 is supported by the first rotating shaft 110, and the cylinder shell 620 of the oil cylinder 600 is limited to translate forward; at this time, the telescopic shaft 610 is pushed forward by the mobile rack 500, and the telescopic shaft 610 is gradually retracted into the oil cylinder 600, thereby damping the forward movement of the mobile rack 500 and reducing a speed of the mobile rack 500 translating forward. That is, a clockwise rotation speed of the second connecting arm 300 and a speed of upward flipping of the pocket 400 are slowed down. When the pocket 400 is flipped downward relative to the long arm 100 to reset, the second connecting arm 300 is rotated counterclockwise around the second rotating shaft 120, the second connecting arm 300 is disengaged from the moving frame 500, the pocket 400 can be quickly flipped downward, a pulling effect of the second connecting arm 300 on the mobile rack 500 is lost, and the telescopic shaft 610 of the oil cylinder 600 is extended backward to push the mobile rack 500 to translate backward and reset. An installation of both the mobile rack 500 and the oil cylinder 600 is limited by the long arm 100, the first rotating shaft 200, the second rotating shaft 300 and the like components, and there is no need to use other locking parts such as screws to connect; thus an overall structure is simple and the installation is very convenient. During working, the cylinder shell 620 of the oil cylinder 600 does not move relative to the long arm 100, and only the telescopic shaft 610 moves telescopically, thereby making a translational movement of the mobile rack 500 more stable and reliable.
In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 3, a spring 130 is sleeved on the first rotating shaft 110. A pin is led out from both ends of the spring 130. The pin 131 at one end is abutted against the long arm 100, and the pin 131 at the other end is abutted against the second connecting arm 300. When the pocket 400 is flipped upward, the spring 130 is subjected to torsional elastic compression. When the pocket 400 flipped downward, the spring 130 elastic resets and assists the pocket 400 to flip downward. The front end of the the cylinder shell 620 of the oil cylinder 600 is abutted against the spring 130, that is, the front end of the cylinder shell 620 of the oil cylinder 600 is indirectly abutted against the first rotating shaft 110 to support the oil cylinder 600 rearward.
In some embodiments of the present disclosure, as shown in FIG. 1, FIG. 2 and FIG. 3, a hook part 310 is extended from a rear side of the second connecting arm 300, and the hook part 310 is presented a curved hook shape towards the rear and upper ward. A protrusion part 510 is provided on the mobile rack 500. In one embodiment, the protrusion part 510 can be a cylindrical protrusion. When the second connecting arm 300 is rotated clockwise, the hook part 310 is rotated with the second connecting arm 300 and abutted against the protrusion part 510, and then pushing the mobile rack 500 to move forward. When the second connecting arm 300 is rotated counterclockwise, the hook part 310 can be quickly detached from the protrusion part 510. The hook parts 310 can be symmetrically provided on a left side and a right side of the second connecting arm 300, and correspondingly, the protrusion parts 510 can be symmetrically provided on a left side and a right side of the mobile rack 500. The hook parts 310 on the left side and the right side of the second connecting arm 300 are paired with the protrusion parts 510 on the left side and the right side of the mobile rack 500 one to one, to ensure a stability when pulling the mobile rack 500 forward.
In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 4, a sliding chute 520 is provided at a bottom of the mobile rack 500, and the sliding chute 520 is extended forward and rearward along the second direction. A support block 630 is provided on the cylinder shell 620 of the oil cylinder 600, and the support block 630 is passed through the sliding chute 520 and abutted against the second rotating shaft 120. Ends of the support block 630 can be configured to be an arc-shaped portion matching a shape of the second rotating shaft 120. The mobile rack 500 and the oil cylinder 600 are supported by the second rotating shaft 120 at the same time. When the mobile rack 500 is translated, a lower side of the mobile rack 500 is lapped on the second rotating shaft 120 to slide forward and rearward relative to the long arm 100, and the sliding chute 520 slides forward and rearward with the mobile rack 500 relative to the support block 630. When the pocket 400 is flipped downward, and the mobile rack 500 is translated rearward, and a front end of sliding chute 520 is abutted against the support block 630, thereby limiting a travel distance of a translation seat moving forward.
In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 3, an extension wall 530 is provided on both the left side and the right side of the mobile rack 500, and the extension wall 530 is extended upward along the first direction toward the long arm 100. An upper end surface of the extension wall 530 is abutted against the long arm 100, and the extension wall 530 and the long arm 100 are in contact to limit a position.
An end of the telescopic shaft 610 can be connected to the mobile rack 500 by means of a snap-in connection or the like. In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 3, a counterbore hole 540 is provided on a rear side wall of the mobile rack 500. The end of the telescopic shaft 610 is inserted into and abutted against the counterbore hole 540, thereby achieving quick installation.
