Abstract

The utility model provides a novel big pivot angle projection frame based on 2UPU &2UU parallel mechanism relates to and is applied to projecting apparatus application field with parallel mechanism. The main purpose is to provide a new installation mode for the hanging projector. The projector is arranged on a movable platform of a parallel mechanism, and the projector can rotate at a large angle by virtue of the structural advantages of the parallel mechanism, so that the projection coverage area of the projector is enlarged. The parallel mechanism adopts a 2UPU &2UU mechanism connection mode, and the projector projection probe is arranged on one side of the parallel mechanism with the moving pair. The equipment can be controlled by adding the motor in the U pair, is simple and convenient to operate, and can realize the swing at a larger angle, thereby achieving the effect of enlarging the projection area of the projector.

Description

Novel large-swing-angle projection frame based on 2UPU &2UU parallel mechanism

The technical field is as follows:

the utility model relates to a novel big pivot angle projection frame based on 2UPU &2UU parallel mechanism, in particular to are applied to the installation of indoor projecting apparatus with a novel parallel mechanism, can enlarge the projection area of projecting apparatus, improve projecting apparatus fixed mounting adjustment in the past and hardly have the problem. The device has the advantages of a parallel mechanism, stable structure, simple control, no accumulated error, high precision and wide application in various occasions such as school classrooms, company meeting rooms and the like.

Background art:

with the development of science and technology, projectors are more and more commonly used, multimedia education of schools, scheme display of company meetings, home theaters used in family bedrooms and scenes of many working societies need to be supported by the projectors.

Along with the popularization of the projector, people experience the use of the projector more and more, and many hanging projectors exist the fixed structure at present, are difficult to adjust. When the projector can not project to the projection curtain perfectly, manual adjustment is needed, and operation is troublesome and laborious. Also, the projection area is limited to a certain extent due to the fixation of the projector mount, which is inconvenient to use.

But the study design a section automatic adjustment's projecting apparatus support can improve people and use the experience of projecting apparatus, makes people life more intelligent. At present, no projection rack in the market can meet the requirements of people, so that equipment is urgently needed to make up for the defects of the existing projection rack.

The invention content is as follows:

in order to solve a great deal of problem of present projecting apparatus support, the utility model provides a novel projecting apparatus support based on 2UPU &2UU parallel mechanism, the projecting apparatus is installed on novel parallel mechanism's the platform that moves, changes along with the position change that moves the platform. Among the 2UPU &2UU parallel mechanism, U represents the universal joint pair, and P represents a sliding pair, and the structure is as shown in figure 1, and stable in structure, easy operation does not have the accumulative error of serial structure, and the security is better.

The utility model discloses based on parallel mechanism, having assembled a great deal of advantage of parallelly connected mechanism, structural rigidity is high, can bear very big power, and is safer, and working range is wide. The operation is simple, and the pose of the mechanism can be controlled by installing the motor on the universal joint.

The technical solution of the utility model is that:

the utility model discloses on the basis of 2UPU &2UU parallel mechanism, install the projecting apparatus on parallel mechanism's the platform that moves, this mechanism has the symmetry, as long as establish the one end of structure as stiff end (quiet platform), the other end is promptly for moving the platform. The movable platform and the static platform are connected by four branched chains, the four branched chains are divided into two 2UPU and two UU, the U pair refers to a universal joint (can be equal to two revolute pairs), and the P pair is a moving pair. The parallel mechanism is a novel mechanism, and no precedent research is carried out at present.

The utility model discloses a parallel mechanism has possessed all advantages of parallel mechanism as the structure basis of projecting apparatus support. The movable platform can have a large range of moving space, the projector is arranged on the movable platform, a large range of projection area can be realized, and a user can control the projection range well only by controlling the rotation in the universal joint and the moving distance of the moving pair.

The utility model provides a most use problem of present projection frame, simple structure is reasonable, uses convenient operation, and is safer, and the cost is controllable, need not artificial adjustment projecting apparatus's mounted position during the use, only need with remote controller control adjustment relevant motion pair can.

Other features of the present invention will be described in more detail in the detailed description that follows

The specific implementation mode is as follows:

the following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

The utility model provides a projecting apparatus mounting bracket based on 2UPU &2UU parallel mechanism, including moving platform, quiet platform, four branch chains and constituteing, install the projecting apparatus on the platform that moves of mechanism, and notice and install the projection end of projecting apparatus in one side of two UPU branch chains, as shown in FIG. 1, improvement projecting apparatus projection area of bigger degree like this.

As shown in fig. 1, the branched chain 1 is in a UPU connection mode, i.e., a universal joint-sliding pair-universal joint connection. The branched chain 2 is a UU branched chain, and shows that two ends of a rigid rod piece are respectively connected with a universal joint pair. Corresponding motors are arranged on the universal joint and the sliding pair, the moving area of the movable platform can be controlled by controlling the motors, the projector is fixedly arranged on the movable platform, and the projector can move along with the movement of the movable platform.

This utility model discloses great improvement hanging projecting apparatus in the life use the convenience, improved the projection area of projecting apparatus for people's life is more intelligent.
