Abstract

The invention discloses a novel curved surface structure of a concave-convex wheel, which comprises a convex part and a concave part, and the convex part and the concave part are connected through a curved surface. The new curved surface structure is characterized in that the curved surface is a stepped structure decreasing from the convex part to the concave part. In the invention, the curved surface of the concave-convex wheel is designed into the stepped structure with reduced torsion force while opening a notebook computer, the fell down phenomenon of the notebook computer during closing can be effectively prevented, and meanwhile, the force applied by a user during the opening process of the notebook computer can become smaller and smaller. Thus, the novel curved surface structure has the advantages of time saving, labor saving, great convenience and good hand feel, and has the function of light opening and heavy closing during the opening and the closing of the notebook computer.

Description

Concavo-convexly take turns novel curved-surface structure

Technical field

The present invention relates to the concavo-convex wheel construction in a kind of rotating shaft of notebook computer, belong to technical field of electronic products.

Background technique

Fig. 1 is traditional concavo-convex camber of wheels structural representation, and Fig. 2 is traditional torque curve schematic representation.

As depicted in figs. 1 and 2: the display/panel bracket of notebook computer is positioned in the rotating shaft by concavo-convex the wheel, and traditional concavo-convex surface of taking turns comprises recess 1 and protuberance 1, connect by curved surface 3 between recess 1 and the protuberance 1, curved surface 3 is a single ramp structure, and this kind structure is not considered notebook in the process of opening, and center of gravity can change thereupon, except that locking, torsion all is the same, and Fell down (auto-closing) phenomenon appears in this kind situation possibly when computer is closed.

Summary of the invention

In order to overcome the deficiencies in the prior art, the object of the present invention is to provide that a kind of to make notebook computer open convenient and strength-saving, function with easy opening and heavy closing, and can prevent effectively that Fell down situation from appearring in notebook computer when closure concavo-convexly take turns novel curved-surface structure.

The present invention is achieved through the following technical solutions:

A kind of concavo-convex novel curved-surface structure of taking turns comprises protuberance and recess, and protuberance is connected by curved surface with recess, it is characterized in that, described curved surface is to recess step structure decrescence by protuberance.

Further, the step structure of curved surface can be divided into three ladders.

The invention has the beneficial effects as follows: the present invention is by becoming concavo-convex curved design of taking turns step structure decrescence, can prevent effectively that Fell down phenomenon from appearring in notebook computer when cutting out on the one hand, user's dynamics can be more and more littler in the opening process of notebook on the other hand, time saving and energy saving, very convenient, and feel is very good, and the function of easy opening and heavy closing is arranged.

Description of drawings

Fig. 1 is traditional concavo-convex camber of wheels structural representation,

Fig. 2 is traditional torque curve schematic representation;

Fig. 3 is the structural representation of one embodiment of the invention;

Fig. 4 is a torque curve schematic representation of the present invention.

Main reference character implication is among the figure:

Embodiment

Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:

Fig. 3 is the structural representation of one embodiment of the invention; Fig. 4 is a torque curve schematic representation of the present invention.

As Fig. 2 and shown in Figure 4: concavo-convexly take turns novel curved-surface structure, comprise protuberance 2 and recess 1, protuberance 2 is connected by curved surface 3 with recess 1, and curved surface 3 is to recess 1 step structure decrescence by protuberance 2, in the present embodiment, the step structure of curved surface 3 is divided into three ladders, and in addition, torque curve of the present invention also is formula decrescence, make notebook in the process of opening or closing, time saving and energy saving, very convenient, and feel is very good.

Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.

Claims

1. concavo-convexly take turns novel curved-surface structure for one kind, comprise protuberance and recess, protuberance is connected by curved surface with recess, it is characterized in that, described curved surface is to recess step structure decrescence by protuberance.
