In the lid closed state, the button spring 33 is compressed by the lid opening button 31 and the button holder 32, thereby generating an upward restoring force F to the button holder 322Said restoring force F2A moment for urging the button assembly 3 to rotate in a direction in which the button assembly 3 is coupled to the lid body 1 is generated for the button assembly 3, that is, when the point of action B and the point of action C are located on the same axis aOn the other hand, the button spring 33 and the cover 1 both generate a moment for urging the button assembly 3 to move in the lid closing direction, and compared with the moment for urging the button assembly to move in the lid closing direction generated by the button spring in the prior art, and the moment for urging the button assembly to move in the lid opening direction generated by the cover to the button assembly, the button spring 33 and the cover 1 in this embodiment both generate a moment for urging the button assembly 3 to move in the lid closing direction, thereby not only eliminating the counter-acting moment of the cover on the button assembly in the prior art, but also generating a moment for assisting the button assembly to move in the lid closing direction, and therefore, for this embodiment, the button spring 33 only needs a light force to ensure the lid closing effect, and therefore, the button spring 33 can be made of a thinner spring, thereby reducing the manufacturing cost of the button spring 33, meanwhile, when the button spring is thin, the button spring is convenient to compress, so that the operation hand feeling is improved.
Example 2:
the present embodiment is basically the same as embodiment 1 in structure and principle, except that:
in this embodiment, as shown in fig. 4, the angle a is 0 °, that is, the axial center a and the action point B are on the same vertical line, and the moment generated by the action force of the cover 1 on the button assembly 3 is zero. That is, when the force of the torsion spring 5 acting on the lid 1 is transmitted to the joint between the lid 1 and the button assembly 3, the moment generated by the force acting on the button assembly 3 is zero. Compared with the prior art, in the embodiment, the lid 1 generates a moment for the button assembly 3 to urge the button assembly 3 to move in the opening direction, in other words, the lid 1 does not generate a moment for the button assembly 3 to move in the opening direction, in the embodiment, the lid 1 does not generate an assisting force for opening and closing the lid 1 nor a resistance force for opening and closing the lid 1, and therefore, it is not necessary to resist the moment for the button assembly by thickening and hardening the button spring.
The utility model can be realized by adopting or using the prior art for reference in places which are not mentioned in the utility model.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
