Referring to fig. 1 to 4, a flip structure according to an embodiment of the present invention includes a body 100, a cover 200, a buffer 400, and a lever 700. The cover 200 is hinged to the body 100 through the hinge 300, the middle portion of the lever 700 is hinged to the body 100, the cover 200 has a driving portion 230 capable of driving the lever 700 to rotate, the buffer 400 is fixedly mounted on the body 100, and the buffer 400 is horizontally disposed. When the cover angle θ is smaller than a threshold α during the falling of the cover 200, the top end of the lever 700 is driven to press the bumper 400 at the bottom end of the lever 700, and the bumper 400 provides a first damping force to the cover 200 in a direction opposite to the movement direction of the cover 200. Referring to fig. 8, the cover angle θ is an angle between the cover 200 and the top end surface of the body 100.

When the driving portion 230 of the cover 200 just contacts the lever 700 during the falling of the cover, the pressing force applied to the buffer 400 by the lever 700 is zero, and the cover angle θ at this time is referred to as a threshold α. The body 100 has a storage chamber with an upward opening, and is substantially in a square shape, the cover 200 is substantially in a rectangular shape, the cover 200 can rotate relative to the body 100 through the hinge 300 to open or close the opening of the storage chamber, the rotation axis of the hinge 300 is generally parallel to the horizontal plane, when the cover 200 opens the storage chamber, the gravity of the cover 200 needs to be overcome, and when the storage chamber is closed, the cover 200 accelerates to rotate under the action of the gravity to close the storage chamber. It is understood that the body 100 may also be a cylinder or a frustum structure, and the cover 200 may also be a circle or a trapezoid, that is, the specific shape and size of the body 100 and the cover 200 may be selected according to the actual requirement, and are not limited herein.

Specifically, when the cover is closed, as shown in fig. 6 and 7, a pressing force is applied to the cover body 200, the cover body 200 starts to rotate downward, and the bottom end of the lever 700 contacts the buffer member 400 but does not press the buffer member 400. As the angle θ of the cover body is smaller and smaller, the gravity force arm is larger and larger, the gravity moment of the cover body 200 is larger and larger, and the falling speed of the cover body 200 is faster and faster. When the cover angle θ is equal to the threshold α, referring to fig. 8 and 9, the driving portion 230 of the cover 200 just contacts the lever 700 and does not rotate the lever 700, and the pressing force applied to the buffer 400 by the lever 700 is zero. When the cover angle θ is smaller than the threshold α, the driving portion 230 drives the top end of the lever 700 to rotate towards the direction away from the body 100, the bottom end of the lever 700 presses the buffer 400, the buffer 400 provides a first damping force to the cover 200, the first damping force is opposite to the movement direction of the cover 200, the influence of the gravity of the cover 200 on the falling speed of the cover 200 is reduced, the cover 200 is buffered to fall, and the damage and the noise to the body 100 and the cover 200 during cover closing are effectively avoided.

In the process of uncapping, exert the holding power to lid 200, lid 200 begins upwards rotation, and lever 700 bottom is stretched on the slow top of bolster 400, and the first damping force production that bolster 400 provided for lid 200 produces the moment of torsion unanimous with the direction of uncapping, and convenience of customers opens lid 200, promotes user's use and experiences. When the cover angle θ is equal to or greater than the threshold value α, the damper 400 is no longer in the pressed state, and the torque disappears.

In addition, the buffer member 400 is fixedly arranged on the body 100, so that the buffer member 400 can not swing in the working process, the operation reliability is improved, the structure is simple, the installation is convenient, the body 100 and the cover body 200 are not required to be changed, and the structures and the use spaces of the body 100 and the cover body 200 are not influenced. Since the arm of force of the lever 700 is long, the required first damping force is small, so that the buffer 400 with a small volume can be adopted, and a good buffering falling effect can be realized.

In some embodiments of the present invention, the threshold α is in a range of 25 ° to 60 °, and if the threshold α is set too large, the volume of the buffer member 400 may be large, which is inconvenient for installing and fixing the buffer member 400. If the threshold α is set too small, the first damping force generated by the cushion member 400 becomes small, and the cushion effect is not significant. In certain embodiments, the threshold α is 45 °.

In some embodiments of the present invention, the hinge 300 is a damping hinge, and during the movement of the cover 200, the damping hinge provides a second damping force to the cover 200 in a direction opposite to the movement direction of the cover 200, so that the cover 200 has a hovering angle range. In the cover opening process, the gravity force arm is smaller and smaller along with the larger and larger cover body angle theta, and the gravity moment of the cover body 200 is smaller and smaller. When the gravity moment of the cover 200 is exactly balanced with the second damping force moment, the cover 200 can hover, and the cover angle θ at this time is referred to as a hover critical angle β. When the cover angle θ is greater than the hovering critical angle β, the gravity moment of the cover 200 is smaller than the second damping force moment, and the cover 200 can also be in the hovering state, that is, the cover 200 has the hovering angle range. Typically, the cover 200 has a hover angle ranging from β to 90 ° for improved usability and stability. The second damping force can prevent the cover body 200 from being automatically or erroneously opened without providing an additional door-lock apparatus, reducing costs. Meanwhile, the cover 200 can be prevented from colliding with the body 100 due to too high speed in the opening or closing process, and user experience is improved.
