Embodiment

For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing Give the better embodiment of the present invention.But the present invention can have many different forms to realize, however it is not limited to herein Described embodiment.On the contrary, the purpose for providing these embodiments is to allow the public to the disclosure It is understood more clearly thorough.

Refering to Fig. 1 to Fig. 3, the present invention proposes a kind of display device, including Flexible Displays module, pedestal and drive device. Wherein, Flexible Displays module includes projection surface S111 and back side S110, and Flexible Displays module has symmetrical centre.Pedestal includes First support S121, second support S122 and the 3rd support S123, first support S121 are arranged at the symmetrical centre of module, and second Support S122 and the 3rd support S123 are symmetrically distributed in first support S121 both sides.Pedestal is integrally used for the weight for carrying display device Amount.Drive device includes power take-off unit and power transmission unit.In the present embodiment, power take-off unit is stepper motor S100.Stepper motor S100 is fixed on first support S121, and imparts power to power transmission unit.Power transmission unit Including gear S130, rack S133 and first connecting rod S131 and second connecting rod S132, first connecting rod S131 and second connecting rod S132 is symmetrically distributed in the both sides of module symmetrical centre.Stepper motor S100 output shafts coaxially assemble with gear S130, so as to Gear S130 is obtained power and realize rotation, gear S130 imparts power to first connecting rod S131 and second connecting rod by rack S132。

Display device also includes rocking bar, and in the present embodiment, rocking bar includes the first rocking bar set relative to symmetrical centre S101 and the second rocking bar S102, the first rocking bar S101 first end and first connecting rod S131 end are hinged, the first rocking bar S101 The second end abutted with the back side S110 of Flexible Displays module.Second rocking bar S102 first end second connecting rod S132 end hinge Connect, the second rocking bar S102 the second end abuts with the back side S110 of Flexible Displays module.In the present embodiment, due to first connecting rod S131 and second connecting rod S132 extend in parallel from the center of Flexible Displays module to both sides, and the first rocking bar S101 and second shakes Bar S102 is respectively hinged at first connecting rod S131 and second connecting rod S132 end, therefore, the first rocking bar S101 and the second rocking bar S102 the second end abuts with back side S110 in the position away from symmetrical centre.

In another embodiment, display device also includes the first support feet S150 and the second support feet S151, when display is set During for placing on the table, the first support feet S150 and the second support feet S151 play a supporting role.

In the present embodiment, the first rocking bar S101 and the second rocking bar S102 first end are provided with bearing pin (not shown), the One connecting rod S131 and second connecting rod S132 is provided with pin-and-hole (not shown), and bearing pin is inserted in pin-and-hole, and thus the two realizes be hinged.

In another embodiment, the first rocking bar S101 and the second rocking bar S102 first end (are not shown provided with pin-and-hole in figure Go out), first connecting rod S131 and second connecting rod S132 are provided with bearing pin (not shown), and bearing pin is inserted in pin-and-hole, and thus the two is real Now it is hinged.

In above-described embodiment, display device is television set or liquid crystal display.

Hereinafter, the course of work of display device of the present invention is described in detail with reference to Fig. 1-4：User by remote control equipment to Display device sends switching command, and after display device receives instruction, Driving Stepping Motor S100 is rotated counterclockwise, stepper motor S100 bands moving gear S130 is rotated counterclockwise, and the rotational band carry-over bar S133 of gear is to the direction translational away from symmetrical centre, band Dynamic first connecting rod S131 and second connecting rod S132 drives the first rocking bar S101 and the to the direction translational away from symmetrical centre Two rocking bar S102 are swung, and then drive the both ends of Flexible Displays module to be bent to symmetrical centre, i.e. state of the display device from Fig. 2 Transform to Fig. 3 state.

When Driving Stepping Motor S100 is rotated clockwise, stepper motor S100 bands moving gear S130 is rotated clockwise, tooth The rotational band carry-over bar S133 of wheel to close to symmetrical centre direction translational, drive first connecting rod S131 and second connecting rod S132 to Close to the direction translational of symmetrical centre, and then the first rocking bar S101 and the second rocking bar S102 is driven to swing, display device is from Fig. 3's State of the state transformation to Fig. 2.

In above-described embodiment, the first rocking bar S101 is identical with the second rocking bar S102 flutter rate, by monosymmetric Power transfer mode so that the Curvature varying of Flexible Displays module is more steady reliable, meanwhile, it ensure that the song of Flexible Displays module Rate is changed using symmetrical centre as reference point, and so itself Curvature varying characteristic with Flexible Displays module matches.

The beneficial effects of the invention are as follows：Prior art is different from, display device of the invention passes through conventional gear connecting rod System transmit power, by hinge arrangement realize plane show with the switching of curved-surface display, its is simple in construction, stable movement, work Make reliably, switching rate is fast.

Embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this The equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations Technical field, it is included within the scope of the present invention.
