Description
The present invention relates to a kind of hinge means, particularly relate to a kind of magnetic hinge unit.
Current portable device, for example cellular mobile phone (cellular phone) pursuit is light, thin, short, little, and all parts all need miniaturization in design.For the cellular mobile phone of staff one machine, from traditional non-cover type button to the existing formula button that covers, and then the Collapsible mobile telephone that is arranged to screen and button branch, its exterior design is more and more lighter and handier.Be designed to example with folding mobile phone, screen and button couple by hinge means, so cellular mobile phone need be opened when conversation, the time spent can not folded up it, makes the volume of cellular mobile phone smaller and more exquisite, is easier to carry.And the employed hinge means of existing cellular mobile phone all adopts the source of spring as hinge means torsion.
With reference to Figure 1A, the schematic diagram of the spring hinge device 100 that its expression is traditional.Spring hinge device 100 comprises axis body 102, the first main bodys, 104, the second main bodys 106 and spring 108, and wherein first main body 104 has peak portion 114 and paddy portion (not showing among Figure 1A), and second main body 106 also has peak portion 116 and paddy portion 126.
With reference to Figure 1B, the schematic diagram after the traditional spring hinge device 100 of its expression is assembled.During assembling axis body 102 is passed first main body 104, second main body 106 and spring 108, the peak portion 114 of first main body 104 and the paddy portion 126 of second main body 106 are engaged, the paddy portion of first main body 104 engages with the peak portion 116 of second main body 106 respectively.It should be noted that, because spring 108 is enclosed on the axis body 102 and is resisted against an end of second main body 106, so utilize the elastic force that compression produced of spring 108 to push second main body 106, can make second main body 106 be close to first main body 104, the two is closely cooperated.
In actual applications, traditional spring hinge device 100 can be installed in one to have in the element of loam cake and base, makes element folding automatically.With folding cellular mobile phone is example, can utilize the loam cake and the base of spring hinge device 100 binding cellular mobile phones, as the rotating shaft between loam cake and base.First main body 104 can be fixed on the base in the operation, second main body 106 then is connected with loam cake.When loam cake and base were closed, the paddy portion of the peak portion 114 of first main body 104 and second main body 106 engaged, and the paddy portion of first main body 104 engages with the peak portion 116 of second main body 106.When the operator opens loam cake, also can drive second main body 106 and rotate synchronously with loam cake, first main body 104 on making it and being fixed on base is separated.
It should be noted that, because second main body 106 is to be socketed on the axis body 102 in movable mode, therefore when second main body 106 is rotated with loam cake, the paddy portion of first main body 104 will be left by its peak portion 116, and move along the hypotenuse that connects first main body, 104 peak portions and paddy portion, cause second main body 106 along axis body 102 outside parallel sliding, thereby compression spring 108.When loam cake opens to certain angle, when making the peak portion 116 of second main body 106 move to the peak portion 114 of first main body 104, it is maximum that the decrement of spring 108 reaches; When loam cake continues to open, when making the peak portion 116 of second main body 106 cross the peak portion 114 of first main body 104, even remove the external force of opening loam cake, also the elastic restoring force of reliable spring 108 pushes back second main body 106, the peak portion 116 that makes second main body 106 is along the hypotenuse of first main body 104 and be resisted against another paddy portion of first main body 104, two main bodys engage again, and make the cellular mobile phone complete opening.As for the action of closed cellular formula mobile phone, then opposite with above-mentioned action.
With reference to Fig. 2, the schematic diagram when it represents spring hinge device 100 operation of traditional collapsible cellular mobile phone.Spring hinge device 100 articulates loam cake 200 and base 202, makes collapsible cellular mobile phone carry out opening and closing movement, and first main body 104 is connected on the base 202, and second main body 106 is connected on the loam cake 200.As shown in Figure 2, abscissa is represented the angle of first main body 104 and 106 rotations of second main body, and ordinate is represented second position of main body 106 on axis body.When cellular mobile phone folding angle is 0 when spending, first main body 104 and 106 of second main bodys are not rotated, and promptly second main body 106 engages with first main body 104, and at this moment, second position of main body 106 on axis body is coordinate a.
When cellular mobile phone folding angle is α, second main body 106 is rotated with loam cake 200, the peak portion 116 that makes second main body 106 breaks away from from the paddy portion of first main body 104, therefore second main body 106 along axis body 102 outside (promptly leaving the direction of first main body 104) parallel sliding to coordinate b, this moment, spring 108 also was compressed, produce one in the other direction the elastic restoring force of the direction of first main body 104 (promptly towards), therefore, when cellular mobile phone is α from being closed into the folding angle, need utilize external force that loam cake 200 is opened, to overcome the elastic restoring force of spring 108.
When loam cake 200 continues to open, when making cellular mobile phone folding angle increase to β, the peak portion 114 of the peak portion 116 of second main body 106 and first main body 104 leans, at this moment second main body 106 outwards slides into coordinate c, reach maximum displacement, spring 108 then is subjected to maximum compression, oppositely produces the elastic restoring force of a maximum.Hence one can see that, is β with cellular mobile phone from being closed into the folding angle, all needs to be continuously applied external force loam cake 200 is opened, to overcome the elastic restoring force of spring 108.
When loam cake 200 continues to open again, when making cellular mobile phone folding angle increase to γ, the peak portion 116 of second main body 106 breaks away from the peak portion 114 of first main body 104, another paddy portion towards first main body 104 moves, and makes second main body 106 along the inside direction of first main body 104 (promptly to) parallel sliding of axis body 102; Originally be subjected to the elastic restoring force of the spring 108 of maximum compression this moment, the direction of second main body 106 to first main body 104 promoted.Therefore, do not need to apply the elastic restoring force that external force can discharge by spring 108 and make loam cake 200 continue to open.
When cellular mobile phone folding angle increases to 180 when spending again, the peak portion 116 of second main body 106 engages with the paddy portion of first main body 104 again, makes second position of main body 106 on axis body 102 turn back to coordinate a.At this moment, the elastic restoring force of spring 108 discharges fully, and loam cake does not need to apply external force just can be opened fully, and spring 108 is also got back to the reset condition that is not subjected to 106 compressions of second main body.
When the above is opened from being closed into for cellular mobile phone, the action situation of spring hinge device 100.Equally, can recognize clearly also that from Fig. 2 cellular mobile phone is from being opened to the situation of closure (180 degree～0 degree).
In sum, when cellular mobile phone when closure state is opened to angle beta, need the operator to apply an external force, loam cake 200 is opened, at this moment second main body 106 and first main body 104 reach maximum labile state (being that both peak portions lean) gradually, and that spring 108 is also gradually reduced is the shortest, produces a reverse elastic restoring force simultaneously.Yet when cellular mobile phone continues to arrive when opening fully from angle beta, compressed spring 108 can discharge elastic-restoring force, promotes second main body it is engaged once again with first main body 104.Therefore, open when being equiped with the cellular mobile phone of spring hinge device 100, in certain angle scope (β～180 degree), have and need not apply external force and its characteristic of opening naturally; Equally, when closing the cellular mobile phone that is equiped with spring hinge device 100, in certain angle scope (β～0 degree), have and need not apply external force and its characteristic of closing naturally.
Though install traditional spring hinge device 100, can make cellular mobile phone have the advantages that nature is opened and closed naturally, but when using spring 108 for a long time, its torsion will reduce, in addition, be subjected to the required spatial constraints of spring 108, the required size of traditional spring hinge device 100 is bigger, and then influences the volume of application product.
According to above-mentioned, the purpose of this invention is to provide a kind of magnetic hinge unit, this magnetic hinge unit utilize the magnetic force same sex to repel each other the principle that there is a natural attraction between the sexes replaces the torsion of traditional spring, the problem that can avoid spring torsion to reduce.In addition, the application product of magnetic hinge unit not only has the characteristic that nature is opened and closed naturally, also the design size features of smaller can be arranged, and simultaneously, also can reduce the part number of hinge means, and cost is reduced.
