Support device for portable projection device

Abstract

The invention discloses a support device for a portable projection device. The support device comprises a fixed assembly and a movable assembly. The fixed assembly comprises a fixing disc, the fixing disc is used for being installed on and fixed to a fixing face, and the fixing disc is provided with a cavity, wherein the movable assembly is sleeved with the cavity. The movable assembly comprises a connecting disc and a telescopic rod mechanism, the connecting disc and the fixing disc are matched to be connected in a butt joint mode or separated, one end of the telescopic rod mechanism is connected to the connecting disc, the other end of the telescopic rod mechanism is provided with a projector installation face, and the portable projection device is installed on the projector installation face. The support device has the advantages of being simple and compact in structure, low in cost, convenient to quickly install and adjust and the like.

Description

technical field [0001] The invention mainly relates to the field of projection equipment, in particular to a bracket device mainly suitable for portable projection equipment and miniature projection equipment. Background technique [0002] With the continuous application and development of various projection technologies such as LCOS, DLP and even laser, various miniaturized and micro-projector products continue to emerge, which greatly improves the portability of projection equipment. Portable projectors are not only used in various office spaces, but also have begun to enter thousands of households. [0003] Portable projectors are extremely rich in product types, some of which are only the size of a palm and weigh only 0.5kg. Their projection effect has surpassed that of common high-definition TVs, and their volume and energy consumption are far lower than that of TVs, and their cost performance is much higher than that of TVs. . In particular, most of the current micro...

AI Technical Summary

Problems solved by technology

After the projector is installed, the position remains basically unchanged, which completely fails to meet the requirements of portable projection equipment that is ready to install, use and disassemble

For example, it cannot meet the requirements of quick and easy use of a projector in multiple rooms in a home

[0006] Some practitioners have proposed a miniature projector bracket composed of a fixed base that can clamp the back plate, a bendable metal tube, a universal head, and a projector base. very troublesome

In particular, the hardness of its bendable metal tube is difficult to control. If it is too hard, it is inconvenient for users to operate, and it is easy to recover after bending. If it is too soft, it is easy to deform, and the projection effect is difficult to guarantee.

[0007] Another practitioner has proposed a Z-shaped folding tabletop projector bracket, which can be easily moved, and can also be folded and lifted arbitrarily. Theoretically, the projection effect can be guaranteed, but it must have a fixed plane similar to a desktop or coffee table, and Portable projectors cannot guarantee this in many occasions

For example: the central position of the family bedroom is often a bed, which cannot provide a fixed surface
