Description

Six-degree-of-freedom projection equipment hanger

Technical Field

The utility model relates to a projection equipment technical field especially relates to an improvement of six degree of freedom projection equipment stores pylon structures.

Background

The shelter is one of important equipment of a maneuvering troops and is commonly used in maneuvering command systems, communication, medical treatment and the like. The ultrashort-focus laser projection equipment is equipment which uses solid laser as a light source, adopts DLP (digital light processing) and reflective short-focus projection and projects laser beams onto a curtain to realize display. The laser projection has bright color and high saturation, can realize large-size projection, saves space, and is particularly suitable for meeting centers, command centers and other places suitable for large-screen display. If the laser projection equipment is installed on the shelter, a flexible and advanced maneuvering command system can be built through the fusion technology and other communication equipment. However, the projection display is different from the common liquid crystal display, the image size of the projection display usually reaches more than 100 inches, and the projection display needs to be matched with a curtain, so that the image is skewed due to the tiny unevenness of the projection device, the projection device is guaranteed to be as horizontal as possible no matter the projection device is installed in a square cabin or an indoor ceiling, and therefore, a hanging frame is generally additionally installed in advance for assisting in leveling the projection device.

The structure and the inner space of the movable shelter have own characteristics compared with the common indoor condition. On one hand, the shelter structure is generally composed of a framework and a skin through welding and filling of an interlayer, and the manufacturing requirements and characteristics of the shelter structure are different from those of manufacturing precision equipment, so that the flatness of the shelter wall is not high; on the other hand, many types of equipment can be installed in the limited space of shelter, and the data line of these equipment need bury in advance in the headspace of cabin top and cabin bottom, and the net height of the interior hoist projection equipment of shelter will be less than general indoor height like this, and equipment such as conference table, control platform can be placed on cabin body ground simultaneously, and this height along distance ground must guarantee enough under the projection screen just to require to prevent to shelter from projection or sight and shelter from. For this purpose, the projection equipment must have enough height to realize projection, and the larger the projection screen, the higher the required hoisting height is, so that if a leveling hanger is additionally arranged between the cabin top and the projection equipment, the space left for the hanger is very limited; and in the third aspect, the shelter has mobility, all equipment in the shelter meets the vibration impact requirement of national military standard vehicle-mounted equipment, and the laser projection equipment is different from common bulb type projection equipment, so that the weight is heavier, the hanging rack not only can be leveled, but also has enough bearing capacity and strength to support the projection equipment, otherwise, the situation of unsafe caused by bumping can occur in the transportation process.

Combining the situations, the laser projection equipment installed in the shelter firstly needs to adjust the pitching, moving or rotating directions of the projection equipment by means of the leveling capability of the hanging frame so as to achieve the effect of leveling projection in a large range, and the adjustment by the laser projection equipment is difficult to achieve; secondly, because the shelter height space is limited, under the requirement of large screen projection, the stores pylon that needs to install additional only occupies the height to be as little as possible closely, just can install in the shelter, once the height exceeds the limit for height requirement, then can't use. And thirdly, the hanging frame mechanism has enough bearing force and strength to ensure that the projection equipment is stably and reliably installed.

At present, the leveling hanging frame mechanism of the projection equipment mainly comprises the following types: one type is a manual or motorized adjustment stage that has only one vertical up and down position on which the projection device is placed. Leveling in other directions is adjusted by 4-5 studs or the like on the bottom of the projection device itself. The realization mode is simple, but the projection is only placed on a platform which can move up and down and is not fixed; the second type of hanging rack realizes leveling by independently adjusting six directions, but the hanging rack is too bulky in structure and cannot be compressed due to lack of linkage design, and the hanging rack is generally used for indoor conditions with low space requirements; the third type of hanging rack is relatively compact in height direction compared with the second type of hanging rack, but the third type of hanging rack usually lacks adjustment of one to two degrees of freedom, cannot adjust up-down height or cannot adjust pitching left and right, and the like, and the compact design of the hanging rack is actually realized through loss of degree of freedom adjustment, and the third type of hanging rack is not a six-degree-of-freedom adjustable mechanism. Such a hanger is often used where the requirements for projection are not too high. The fourth type is to realize six-degree-of-freedom adjustment through a universal joint and other direction adjustment, and the structural form is relatively compact, but the bearing capacity is limited, and the six-degree-of-freedom adjustment can only be used with common projection equipment.
