Embodiment

[0032] Such as figure 1 As shown, the present invention consists of 1000 actuators, numbered from W01J01 to W20J50. The overall arrangement is square. Through the upper computer programming, all the actuators are controlled to move according to the system requirements. Through the up and down movement of the actuators, the plane image is presented in a three-dimensional manner through the three-dimensional up and down movement.

[0033] Such as figure 2 with image 3 As shown, the actuator includes a drive motor 1, a mounting base plate 2, a linear guide 3, a snap ring 4, a drive motor housing 5, an actuator mounting housing 6, a guide sleeve snap ring 7, a guide sleeve 8, a mechanism housing 9, and a driving wheel 10. , Toothed belt 11, driven wheel 12, mechanism cover mounting plate 13, driven wheel mounting plate 14, and driving wheel mounting plate 15;

[0034] The mounting base plate 2 is fixed under the actuator mounting housing 6, the drive motor 1 is fixed on the mountin...

Abstract

The invention relates to a stereoscopic lifting screen capable of absorbing noise. According to the realization method of the stereoscopic screen, 1000 independent execution mechanisms are used, and images are displayed in a stereoscopic mode. The lifting screen has the function of absorbing noise, the work noise low speed of the lifting screen is controlled within 60db, and the work noise high speed of the lifting screen is controlled within 70db. A driving motor, an installation base plate, a linear guide rail, a clamping ring, a driving motor outer cover, an execution mechanism installation outer shell, a guide sleeve clamping ring, a guide sleeve, a driving wheel, a toothed belt, a driven wheel, a mechanism outer cover installation plate, a driven wheel installation plate and a driving wheel installation plate are all installed in the mechanism outer cover, and spreading between a noise source and a noise receiver is blocked.

Description

Technical field [0001] The invention relates to a sound-absorbing three-dimensional lifting screen. The realization of the three-dimensional screen is to use 1000 independent actuators to realize the presentation of images in a three-dimensional manner; the lifting screen has the function of absorbing noise, making the working noise of the lifting screen The slow speed is controlled within 60db, and the fast speed is controlled within 70db. Background technique [0002] The success of the Beijing Olympics has had a profound impact on the world. The "Hezimo" electromechanical system project in the Beijing Olympic Museum Hezi Hall is a key project of the Beijing Olympic Museum. The level of the "Hezimo" project is directly related to the overall interpretation effect of the Hezi Hall. [0003] The electromechanical system of "Hezimo" needs to give full play to the large-scale and large-space advantages of the Beijing Olympic Museum, adopt an open layout, reflect the overall style of...
