DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figures 1 to 4 A cover opening structure, characterized in that it includes a box body 1 and a cover body 2, the box body 1 and the cover body 2 are rotatably connected via a rotating shaft 3, a torsion spring 4 is also provided between the box body 1 and the cover body 2, the torsion spring is a parallel double torsion spring, the torsion spring 4 includes a transverse connecting rod 41 abutting against the box body 1, and both ends of the transverse connecting rod 41 are provided with torsion arms 42 perpendicular to the transverse connecting rod 41, the torsion arm 42 includes at least three turns of helical torsion spring structure 421, and the other end of the torsion arm 42 is provided with a plug-in end 43 plugged into the cover body 2.

[0025] At this time, in order to ensure that the torsion spring 4 provides better torque for the opening and closing cover during use, in this embodiment, the plug-in end 43 of the torsion spring 4 is a rod structure parallel to the transverse connecting rod 41, and the plug-in end 43 faces the middle position of the transverse connecting rod 41.

[0026] As for the torsion arm 42, in this embodiment, the torsion arm 42 further includes a longitudinal connecting rod 422 connected to the transverse connecting rod 41, the longitudinal connecting rod 422 is perpendicular to the transverse connecting rod 41, and the torsion spring structure 421 is connected to the transverse connecting rod 41 through the longitudinal connecting rod 422. That is, at this time, the torsion spring 4 includes the transverse connecting rod 41, and the longitudinal connecting rods 422 are vertically arranged at both ends of the transverse connecting rod 41, and the other end of the longitudinal connecting rod 422 is provided with at least three turns of the spiral torsion spring structure 421, and the other end of the torsion spring structure 421 is a plug-in end 43, at this time, the plug-in end 43 is arranged in parallel with the transverse connecting rod 41, and the other end (the floating end) of the plug-in section faces the middle position of the transverse connecting rod 41.

[0027] As for the connection between the torsion spring 4 and the cover body 2, in this embodiment, the cover body 2 is provided with a rotation hole 21 parallel to the axis of the rotation shaft, and the plug-in end 43 of the torsion spring 4 is inserted into the rotation hole 21. At this time, the axis of the rotation hole 21 is arranged parallel to the axis of the rotation shaft between the cover body 2 and the box body 1, and the torsion spring 4 is a parallel double torsion spring as a whole, so that in the process of opening and closing the cover, the torsion spring 4 can provide a certain torque for opening and closing the cover. Specifically, in the process of use, when the opening angle of the cover is greater than 60°, the two end force arms inside the parallel double torsion spring will exert force upward, and the cover body 2 can automatically open to the maximum position of 95°. When the cover body 2 is closed and rotated to the 30° position, the two end force arms inside the parallel double torsion spring will exert force downward, and the cover body 2 will automatically close to the 0 degree position, thereby closing the cover body 2 and the box body 1.

[0028] During use, in order to keep the torsion spring 4 and the box body 1 in a certain positional relationship, the box body 1 is provided with a rotating platform 11, and a limiting boss 12 is provided on the upper side of the rotating platform 11. A rotation gap is provided between the limiting boss 12 and the rotating platform 11, and the transverse connecting rod 41 is inserted in the rotation gap. The transverse connecting rod 41 is clamped in the rotation gap between the limiting boss 12 and the rotating platform 11, and the plug-in end 43 of the other end of the torsion spring 4 is plugged and fixed with the rotation hole 21 of the cover body 2, so that during the process of opening and closing the cover, the torsion spring 4 is between the cover body 2 and the box body 1, thereby ensuring the stability of the opening and closing process.

[0029] Specifically, at this time, since the transverse connecting rod 41 has a certain length, in order to ensure the limiting effect of the limiting boss 12 on the transverse connecting rod 41, in this embodiment, two limiting bosses 12 are provided, which are respectively located at the longitudinal connecting rod 422 positions close to the two ends of the transverse connecting rod 41, and the limiting boss 12 is located at the inner side of the two longitudinal connecting rods 422. At this time, the two limiting bosses 12 are located at the inner side of the longitudinal connecting rod 422, which can further limit the movement of the transverse connecting rod 41 along the axial direction.

[0030] The box body 1 is provided with a first rotation shaft 3 hole and a second rotation shaft 3 hole connected to the rotation shaft 3 of the cover body 2, and the first rotation shaft 3 hole and the second rotation shaft 3 hole are both located at the inner side of the plug-in ends 43 at both ends of the torsion spring 4. In this way, the torsion spring 4 is arranged at the outer side of the rotation shaft, which increases the stability of the cover body 2 and the box body 1 during use.

[0031] In order to prevent the transverse connecting rod 41 from interfering with the electronic components of the box body 1 (the charging module in this embodiment) during use, the transverse connecting rod 41 is a bending structure, and an avoidance bend 411 is provided in the middle of the transverse connecting rod 41, and a corresponding avoidance bend 411 is provided at the position of the electronic components. In this way, during the process of opening and closing the cover, the torsion spring 4 will not contact the electronic components at the position of the transverse connecting rod 41, that is, it will not affect the normal operation of the torsion spring 4.

[0032] In the process of closing the cover 2 and the box body 1, in order to achieve the adsorption and fixation of the cover 2 and the box body 1, in this embodiment, the lower side of the cover 2 is provided with a first magnetic member, and the box body 1 is provided with a corresponding second magnetic member, and when the cover 2 and the box body 1 are closed, the first magnetic member and the second magnetic member are adsorbed and fixed. The cover 2 and the box body 1 are adsorbed and fixed together by the adsorption and fixation effect of the second magnetic member and the second magnetism, so that the cover 2 and the box body 1 are fixed together in the closed state.

[0033] like Figure 5 As shown, a charging box adopts the above-mentioned opening structure and is used for a wireless Bluetooth headset charging box.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
