Projection device with 5G wireless communication and up-and-down and front-and-back adjustment

Abstract

The invention provides a projection device with 5G wireless communication and up-and-down and front-and-back adjustment, belongs to the technical field of projection devices, and aims to solve the problem that after an existing projection device is used, part of people directly sleeve a projection device at the moment, and then the service life of the projection device is shortened. The projection device comprises a fixed top plate; a lifting mechanism is arranged at the bottom of the fixed top plate; and an angle adjusting mechanism is arranged at the bottom of the lifting mechanism, and a front-back adjusting mechanism is arranged at the bottom of the angle adjusting mechanism. After a wind speed sensor senses that wind power disappears, a signal indicating that the wind power disappears is transmitted to a control box, then a lifting motor is started through the control box, so that a projector main body is stored in a protection mechanism for protection, the whole protection process does not need manual operation, so that time and labor are saved, heat of the projection device can be effectively dissipated, and the service life of the projection device is prolonged.

Description

technical field [0001] The present invention belongs to the technical field of projection devices, and more specifically relates to a projection device with 5G wireless communication and up, down, back and forth adjustment. Background technique [0002] 5G mobile networks Like earlier 2G, 3G and 4G mobile networks, 5G networks are digital cellular networks in which a provider's covered service area is divided into many small geographic areas called cells. With the continuous development of technology, more and more projectors have begun to adopt 5G wireless communication technology. [0003] For example, the application number: CN201710785916.6 The present invention provides a projection device, including an optical machine module and a color wheel module. The optical-mechanical module includes: an optical-mechanical housing, on which grooves are arranged; and a first electrical connection structure, which is arranged on the optical-mechanical housing. The color wheel modu...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a projection device with 5G wireless communication and up and down adjustment, to solve the problem that although the existing projection device can be protected by putting a protective cover on the outside of the projection device after use, the projection After the device is used, the cooling fan on the projection device will still rotate for a period of time, and some personnel will directly put the protective cover on the outside of the projection device at this time, so that the heat of the projection device cannot be effectively dissipated, thereby reducing the service life of the projection device and although the existing projection device has a lifting structure, the lifting structure generally adopts a scissor mechanism type lifting structure, and this type of lifting structure is very unstable when driving the projection device to lift; There is an angle adjustment structure, but when adjusting the up and down angle of the projection device, people need to use tools to loosen the bolts for adjustment, which reduces the convenience of adjusting the up and down angle of the projection device
