Problems solved by technology

Although this patent document achieves the effect of convenient storage, the distance between the projector and the projection whiteboard in this patent document is fixed, which is only suitable for short focal length projection. If the above concept is applied to laser TV projection or other long focal length projection, The projection equipment occupies a large area. Similarly, the distance between the projector and the projection whiteboard is fixed, and the magnification function of the projector itself cannot meet the demand in many occasions.

Embodiment 1

[0024] refer to Figure 1 to Figure 4 As shown, an integrated projection device provided in this embodiment includes: a projector 10, an infrared communication module 101, a control module 102, a motor drive module 103, a retractable device, a rotating shaft 30, a support frame 40 and a projection screen 50, The telescopic device includes: a chute 201 and a slide bar 202, the projector 10 is fixedly mounted on the outer surface of the chute 201, one end of the slide bar 202 is slidably connected in the chute 201, and the other end of the slide bar 202 is pivotally connected by a rotating shaft 30 On the supporting frame 40 , the supporting frame 40 is provided with an accommodating groove (not shown), and the bracket of the projection screen 50 is inserted into the accommodating groove to be fixed. Both the projector 10 and the housing of the supporting frame 40 are provided with locking holes 60 . The receiving end of the infrared communication module 101 and the control modu...

Embodiment 2

[0033] refer to Figure 5 As shown, the integrated projection device provided by this embodiment is the same as the structure of Embodiment 1, the only difference is that one end of the projector 10 forms a pivot connection with the sliding groove 201 of the retractable device, and the pivot structure and The pivot structure of the support frame 40 is the same as that of the sliding bar 202 . The purpose of this structure is to adjust the projection angle of the projector 10 through the pivot structure, so as to make the projection more flexible.

[0034] Through the technical solution provided by the present invention, through the telescopic movement of the telescopic device, the projection screen 50 is driven to adjust the distance from the projector 10, and the size of the projection screen can be freely adjusted to meet the needs of different occasions or users; the support frame 40 and telescopic The device is pivotally connected. When the projection equipment is not in ...

Abstract

The invention relates to integral projection equipment, which can freely adjust the size of a projection picture, is integrally accommodated, and is small in floor area after being accommodated, and convenient to operate. The integral projection equipment comprises a projector, a projection screen, a telescopic device and a support frame, wherein a telescopic end of the telescopic device is connected with the projector; the other telescopic end is pivoted to the support frame; an accommodating groove is arranged on the support frame; and a bracket of the projection screen is inserted into the accommodating groove to be fixed. Through telescopic motion of the telescopic device, the projection screen is driven to adjust the distance to the projector; the size of the projection picture can be freely adjusted; and the requirements of different occasions or users are met. The support frame is pivoted to the telescopic device; the telescopic device is contracted when the projection equipment is not used; and the support frame and the projection screen are folded on the projector, so that integral accommodation is achieved; and the integral projection equipment is small in floor area after being accommodated, and convenient to operate.

Description

technical field [0001] The invention relates to a projecting device which can freely adjust the size of a projection screen, is integrated in storage, occupies a small area after storage, and is easy to operate. Background technique [0002] Nowadays, multimedia technology is widely used, and multimedia projection devices are mainly used for image projection of projectors. The various parts of existing projection devices are generally separated, such as projection screens, projectors and hangers, etc. It takes a lot of time to arrange the projection device. At the same time, when not in use, the projector lens cannot be effectively protected due to the activities of people or pets, and it is easy to be scratched and affect the image quality. [0003] The Chinese invention patent application number is: CN201410664956 discloses a multimedia short-focus projection device, including a projection whiteboard, a short-focus projector and a frame, the projection whiteboard is instal...
