The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Example (b):
as shown in fig. 1 to 5, a semi-automatic opening and closing box is formed by combining a box cover 1 and a box body 2 to form an accommodating cavity 20, wherein the box body 2 and the box cover 1 are provided with a rotating shaft pivoting structure 3, the left end and the right end of the joint of the box body 2 and the box cover 1 are respectively provided with an accommodating groove 4, and the left end and the right end of the box cover 1, which correspond to the accommodating groove 4, are respectively provided with a cam 12; the accommodating groove 4 is internally provided with an elastic structure, the elastic structure is an elastic sheet 5, the elastic sheet 5 is in a one-piece bending shape, as shown in fig. 2, a long end 51 and a short end 52 are formed after bending, the elastic sheet 5 is arranged in the accommodating groove 4, the long end 51 and the short end 52 are both arranged upwards or obliquely upwards, the short end 52 of the elastic sheet 5 is positioned in the accommodating groove 4 and is abutted against the side wall of the accommodating groove 4, the long end 51 of the elastic sheet 5 is a sliding surface, the long end 51 extends outwards of the accommodating groove 4, and one surface of the long end 51 of the elastic sheet 5 opposite to the short end 52 is abutted against the cam 12 of the box cover 1.
The section of the cam 12 of the box cover 1 presents an outward sharp angle α, the lateral outer edge of the cam 12 corresponding to the top of the sharp angle α is an abutting edge 121, the abutting edge 121 linearly abuts against the long end 51 (sliding surface) of the spring 5, and the cam 12 can slide back and forth on the long end 51 (sliding surface) of the spring 5, when the cam 12 slides on the long end 51 of the spring 5, the spring 5 abuts against the cam, the long end 51 of the spring 5 is pressed towards the short end 52, the vertical connecting line β at the linear abutting position of the rotating shaft 31 of the pivoting structure 3 of the box cover 1 and the box body 2 and the cam 12 abuts against the long end 51 (sliding surface) is reached by the rotating shaft 31 of the box cover 1 and the cam 12, when the vertical connecting line β forms a 90 degree angle with the tangent of the long end 51 (sliding surface) (vertical), in this embodiment, when the vertical connecting line β forms a 90 degree angle with the long end 51 (sliding surface) (vertical), the spring 5 reaches the, the long end 51 and the short end 52 of the elastic sheet 5 are pressed most, as shown in fig. 3, in this embodiment, the included angle between the box cover 1 and the box body 2 is 60 degrees in the maximum deformation state; after the maximum deformation state, the elastic sheet 5 can make the abutting edge 121 of the cam 12 abutting on the long end 51 (sliding surface) slide upwards or downwards along the long end 51 in the process of restoring deformation, and finally the opening or closing of the box cover 1 is realized.
If the box cover 1 needs to be opened, when a user only needs to manually open the box cover 1 to an angle of 60 degrees, the cam 12 presses the long end 51 of the elastic piece 5, so that the elastic piece 5 reaches a maximum deformation state, at this time, the box cover 1 is released, the extrusion force of the cam 12 on the long end 51 (sliding surface) of the elastic piece 5 is reduced, the abutting edge 121 of the cam 12 abutting against the long end 51 (sliding surface) of the elastic piece 5 in the deformation recovery process can only select to continuously slide upwards or downwards, and because the cam 12 is the opening and upwards sliding process, the abutting edge 121 of the cam 12 continuously slides upwards along the long end 51 (sliding surface) along the opening inertia, which is a semi-automatic opening mode, and finally, the complete opening of the box cover 1 is realized, as shown in fig. 5; in the maximum deformation state of this embodiment, the long end 51 of the elastic sheet 5 forms an angle of 75 degrees with the horizontal reference plane of the bending bottom of the elastic sheet 5; when the box cover 1 is completely opened, the long end 51 of the elastic sheet 5 forms an angle of 77 degrees with the horizontal reference plane of the bent bottom of the elastic sheet 5, and the included angle between the box cover 1 and the box body 2 forms an angle of 80 degrees.
When a user needs to close the box cover 1, and only needs to close the box cover 1 to an angle of 60 degrees, the cam 12 presses the long end 51 of the elastic sheet 5, so that the elastic sheet 5 reaches a maximum deformation state, at this time, the box cover 1 is released, the pressing force of the cam 12 on the long end 51 (sliding surface) of the elastic sheet 5 is reduced, the abutting edge 121 of the cam 12 abutting against the long end 51 (sliding surface) of the elastic sheet 5 in the deformation recovery process can only select to continuously slide upwards or downwards, and because the cam 12 is in the downward sliding closing process, the abutting edge 121 of the cam 12 continues to slide downwards along the long end 51 (sliding surface) along the inertia of the closing, which is a semi-automatic closing mode, and finally, the complete closing of the box cover 1 is realized, as shown in fig. 6; when the box cover 1 is closed, the end of the long end 51 of the elastic sheet 5 leans against the inner side of the cam 12 of the box cover 1, and the long end 51 of the elastic sheet 5 forms an angle of 85 degrees with the horizontal reference plane of the bent bottom of the elastic sheet 5.
