Background technique
With the development of science and technology, the display technology for public arenas such as advertisement, publicity and decorations is by traditional static state
Display (such as poster) develops into the electronic display technology using screen as carrier, wherein electronic curtain is shown mainly by tiny
Pixel is composed, and in conjunction with colorful light, richer, true visual effect can be provided for audience, thus more quasi-
Really, corresponding information is vivo conveyed.
Specifically, existing electronic display technology can be divided into static status display and Dynamically Announce, wherein Dynamically Announce can mention
For the display picture comprising movement, ornamental value is more preferable, likes by masses.Existing most of electronic display screens are all fixed
Planar structure, either statically or dynamically information can only be shown on two-dimensional space, screen itself cannot bring dynamic display effect.
In order to obtain the display effect that three-dimensional sense is stronger, content is richer, more dynamic, occurs dynamic display dress in the prior art
It sets, this dynamic display device is composed of several display units, and each assembled unit can make stretching motion, so that screen
Curtain itself can mould a variety of three-dimensional kinematic modelings, so that the more abundant shock of whole bandwagon effect.Such as Granted publication
Disclosed in utility model patent number for 105937751 A of CN " a kind of telescopic matrix lamp and the expansion screen manufactured with it ".It is existing
The telescoping mechanism of some dynamic display devices mainly uses lead screw transmission mechanism, and existing deficiency is:
1, the shorter 3 d display device of distance of stretch out and draw back is suitable for as telescoping mechanism using lead screw transmission mechanism, when flexible
Stroke it is larger when, on the one hand, the length of screw rod is too long, forms long cantilever design, bad stability when expansion screen is mobile,
On the other hand, the difficulty of processing of long lead screw is big, and manufacturing cost is higher.
2, lead screw transmission mechanism is by the linear movement for being converted to screw pitch direction of screw rod, the speed of linear movement
Slowly, when applying in the expansion screen of big stroke, it is more abundant and fast-changing vertical that movement speed is unfavorable for moulding slowly form
Body kinematic modeling.
3, using lead-screw drive mechanism as telescoping mechanism, screw rod is arranged inside lampshade, there is provision of and lead outside lampshade
To mechanism, so that the inner space of lampshade cannot be made full use of, so that structure is not compact enough, volume is big.
