Please follow the E with reference to Fig. 3 A to Fig. 3, Fig. 3 A to Fig. 3 E is the illustrative view of the housing folding of electronic equipment according to an embodiment of the invention.
When electronic equipment 20 was collapse state, upper shell 230 was superimposed on lower shell body 220 (as shown in Figure 3A).Mechanical analysis as shown in Figure 3A, elastic component 140 produce a tensile force f to first conjunction 120 and second conjunction 130 respectively.And because line L1 and line L2 are also non-parallel but press from both sides an acute angle theta, and the confluce of line L1 and line L2 is away from second rotating shaft 112, to make that tensile force f is less than the arm of force distance B 2 of tensile force f with respect to second rotating shaft 112 with respect to the arm of force distance B 1 of first rotating shaft 111 near first rotating shaft 111.Thus, the torsion that produces of 140 pairs of second rotating shafts 112 of elastic component is the torsion that produces greater than 140 pairs of first rotating shafts 111 of elastic component.
Therefore when user's application of force is launched upper shell 230 relative lower shell bodys 220, more easily overcome by user's the application of force because the torsion that 140 pairs of first rotating shafts 111 of elastic component produce is less, the rotating shaft 111 of winning will be rotated earlier.Further, connection piece 110 pivots relative first conjunction 120, makes side body 210 and lower shell body 220 present a level, 230 relative lower shell bodys 220 of upper shell and be expanded to a plumbness (shown in Fig. 3 B).
When the user continues upper shell 230 application of forces and since bounding means 114 will be resisted against first end 141 of elastic component 140 make connection piece 110 more relative first conjunction 120 pivot, make that second rotating shaft 112 then is forced to rotate.Further, second conjunction 130 pivots relative connection piece 110, makes upper shell 230 relative lower shell bodys 220 and is expanded to a level (shown in Fig. 3 C).At this moment, the mechanical analysis shown in Fig. 3 C, elastic component 140 still produces a tensile force f to first conjunction 120 and second conjunction 130 respectively.Because line L1 and line L2 are also non-parallel but press from both sides an acute angle theta, and the confluce of line L1 and line L2 changes near second rotating shaft 112 and away from first rotating shaft 111, makes that tensile force f is greater than the arm of force distance B 2 of tensile force f with respect to second rotating shaft 112 with respect to the arm of force distance B 1 of first rotating shaft 111.Thus, the torsion that produces of 140 pairs of second rotating shafts 112 of the elastic component torsion that will produce less than 140 pairs of first rotating shafts 111 of elastic component.
Therefore when user's application of force folds upper shell 230 relative lower shell bodys 220, more easily overcome by user's the application of force because the torsion that 140 pairs of second rotating shafts 112 of elastic component produce is less, make second rotating shaft 112 to be rotated earlier.Further, second conjunction 130 pivots relative connection piece 110, makes upper shell 230 relative lower shell bodys 220 and folds to plumbness (shown in Fig. 3 D).
When the user continues upper shell 230 application of forces and since bounding means 113 will be resisted against second end 142 of elastic component 140 make second conjunction 130 can't be more relatively connection piece 110 pivot, make the rotating shaft 111 of winning then be forced to rotate.Further, connection piece 110 pivots relative first conjunction 120, makes that upper shell 230 is superimposed on lower shell body 220 (shown in Fig. 3 E).Therefore, present embodiment is that the line L2 by the axle center of axle center to the second rotating shaft 112 of the line L1 of first end, 141 to second ends 142 of elastic component 140 and first rotating shaft 111 presss from both sides an acute angle theta, and the elastic force that makes elastic component 140 produce causes different torsion to first rotating shaft 111 and second rotating shaft 112.Thus, when the user carries out folding to upper shell 230 and lower shell body 220, first rotating shaft 111 and second rotating shaft 112 will have the priority of rotation and be convenient to user's operation.In addition, above-described embodiment is to press from both sides an acute angle theta with line L1 and line L2 to reach distribution first rotating shaft 111 and the priority of second rotating shaft 112 when rotating, yet this feature is non-in order to limit the present invention.For instance, in the middle of other embodiments, also can distribute first rotating shaft 111 and second rotating shaft 112 priority when rotation by a spin friction coefficient of adjusting first rotating shaft 111 and second rotating shaft 112.
According to electronic equipment and the twin axle pivot thereof of above-described embodiment, wherein the structural design of twin axle pivot is the simple in structure of existing pivot, therefore can reduce the cost of twin axle pivot.In addition, owing to use the electronic equipment of the twin axle pivot of present embodiment, be to wear groove by the elongated of side body to wear for the signal wiring of winding displacement kenel.Thus, the signal wiring can directly connect lower shell body and upper shell with the winding displacement kenel, is not the signal wiring of twisted wire kenel and need not transfer.And the line at the two ends by elastic component is binding clip one acute angles with the axle center of axle center to the second rotating shaft of first rotating shaft, makes win rotating shaft and second rotating shaft have the priority of rotation and be convenient to operation.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
