As shown in Figure 7 to 9, when first shell 11 and second shell 12 allow two groups of fixed shells with respect to overturning closure 111,121 and movable housing 112,122 when spacing out respectively, pass through the same of the first slipping mechanism 3 and the second slipping mechanism 3 ' The elastic returning effect of Shi Zuodong and two return unit 335, can make the limiting section 333 of the support plate 331 of two groups of slipping mechanisms It is separated respectively with the first stop section 23 of pedestal 2, the opposite sliding in the second stop section 26, to make two limiting sections 333 while take off Limitation from the first stop section 23 and the second stop section 26, and two Supporting plates 33 is allowed to be respectively relative to two the first sliding blocks 32 Arcuate oscillating motion is carried out, two support plates 331 is made to deviate an angle respectively, while two connecting plates 332 being allowed to be pressed on each the respectively The inclined-plane 322 of one sliding block, 32 one end and each support plate 331 is allowed to be pressed on the first supporting surface 314 and the second supporting surface 373, So as to forming multiple contact surfaces with share loads and even support, and make the stepped construction of interlock plate 34 that can lie low in limiting groove 349 slot inner bottom surface, to prevent interfering the situation of interlock plate 34 when the breasting of support plate 331.And due to two of two slipping mechanisms One angle of opposite offset of support plate 331, then will form an accommodating space 14 to accommodate the bent intermediate position of flexible display 13.
Please refer to shown in Fig. 7, Figure 10, Figure 11, the mistake of closure is overturn relatively in first shell 11 and second shell 12 Cheng Zhong, since the third sliding part 362 of 36 one end of mediation member interlocks the first sliding part 348 of moving member 345, and centre passes 4th sliding part 363 of 36 other end of moving part is contained in the second sliding part 352 in the V-shaped fluting 351 of moving part 35.When Mediation member 36 rotates a rotational angle θ first with simultaneous linkage moving member 345 and moving part 35, and is moved in parallel with opposite direction When, if the distance that moves horizontally with moving member 345 is set as S1, the relative level moving distance of moving part 35 is set as S2, then
S1=r1 (distance in the axle center of the first sliding part 348 to fulcrum 361) * tan θ (rotational angle)
S2=r2 (distance in the axle center of the 4th sliding part 363 to fulcrum 361) * sin θ (rotational angle)
Therefore, S1 < S2
Wherein, if mediation member 36 rotates a rotational angle θ and then continues to rotate identical rotational angle θ, herein The relative level moving distance of moving part 35 is set as S3 by period, then S3 < S2;Similarly, moving member 345 move horizontally distance also Distance greater than S1, it is subsequent to be illustrated with technical characteristic of the invention.
Therefore, when mediation member 36 is that axle center original place constant speed rotates with fulcrum 361, the moving member 345 interlocked exists It is respectively formed moving horizontally for long and short distance during the front and rear sections of rotation, to generate speed movement first quick and back slow, and is connected Dynamic moving part 35 can equally be moved in parallel with speed first quick and back slow relative to 345 opposite direction of moving member.So as in first shell Movement incipient stage of the body 11 with second shell 12 relative to overturning closure (can be considered that mediation member 36 first rotates an angle of rotation θ Degree), it can allow the limiting section 333 of support plate 331 and 23 quick separating of the first stop section of pedestal 2, make two support plates 331 relatively An angle is deviated, to gradually form the accommodating space 14 that can accommodate 13 bent intermediate position of flexible display, in the process Flexible display 13 bent intermediate position can synchronize it is mobile with the direction far from pedestal 2.And in first shell 11 and second The movement sustained period of the opposite overturning closure of shell 12 (can be considered that the connecting of mediation member 36 is rotated further by an identical rotational angle θ), since the moving distance of moving member 345 and moving part 35 becomes smaller simultaneously, then the bent intermediate of flexible display 13 can be prevented Position completely disengages the support of pedestal 2, and pedestal 2 and two support plates 331 is made to provide flexible display 13 from different directions respectively Bent intermediate position lean on, so as to enabling the bent intermediate position of flexible display 13 to be effectively contained in accommodating space 14 In, with the situation for preventing intermediate bent section position to be oppressed or suspend and the effect for avoiding weakening compensation folding path.
Therefore, the present invention has the advantage that
1, the present invention passes through the connection relationship and knot between the first sliding block, Supporting plate, interlock plate and a cam link module Structure feature can be effectively thinned the entirety of compensation folding path mechanism, can further simplify and be produced into using part with reducing This.And the first connecting portion arcuate oscillating motion by the second connecting portion of Supporting plate relative to the first sliding block, it generates similar shaftless The effect that freely swings of seesaw is also facilitated to reduce volume and be dropped that is, without being pivotally connected as the prior art is general with entity axis Low thickness in favor of the effect of slimming makes that accommodating space can be conceded in integrally bending to accommodate the bending of flexible display Position among shape, and in integrally flattening, but can the flattening shape centre position to flexible display form stable support.
2, the present invention has the mediation member of third sliding part by one end to interlock the first cunning possessed by interlock plate Dynamic portion and form relative movement, and with the 4th sliding part of the mediation member other end to interlock the second cunning possessed by moving part Dynamic portion makes moving part mobile with the direction opposite with interlock plate, therefore, can the fixation shell for connecting the first sliding part with connect In the folding process of the movable housing of moving part, mobile effect first quick and back slow is formed, can compensate for folding path difference to reach Effect makes faster to form the space that can accommodate flexible display crooked position, and can avoid the power pair of jackknife action Flexible display is caused to pull or be pushed, to extend the service life of flexible display.
3, in opposite turning unfolding, the limiting section of support plate one end can lead to for first shell of the invention and second shell The guiding of the first guiding face and the second guiding face is crossed, so that limiting section smoothly moves, then overlaps the first gear for being limited in pedestal In stop, so as to allowing two support plates to support flexible display therefore can be in support plate bending deformation, still upwards simultaneously It can ensure that stable transmission effect.
Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
