Panel lifting device and multimedia terminal

Abstract

The invention discloses a panel lifting device and a multimedia terminal. The device comprises a driving assembly and a guide assembly, the driving assembly comprises sprockets, chains and a motor, the number of the sprockets is two, the sprockets are arranged in the height direction, the chains are arranged around the sprockets, the motor is arranged on one side of the chains, a power output shaft of the motor is in transmission connection with the sprockets, and the sprockets are used to drive the chains to move in the height direction; and a guide assembly comprises a guide rod and slidingblocks, and the sliding blocks are arranged on the guide rod in a sleeved mode and connected with the chains and a panel. According to the device, the position where the driving assembly is arranged is changed from the upper part or the lower part of a lifting device to one side of the lifting device, the occupied space of the lifting device in the whole device is reduced, the structure where theguide rod is driven by the chains to get on the sliding blocks is adopted to ensure that the lifting process moves along the straight line all the time, the lifting height in the height direction is increased, and solutions for the increase of the size of the panel and the miniaturization of the multimedia terminal while the lifting height is the same are provided.

Description

technical field [0001] The invention relates to the technical field of multimedia terminal equipment, in particular to a panel lifting device and a multimedia terminal. Background technique [0002] With the continuous improvement of multimedia equipment technology, a large number of multimedia equipment has begun to be used in railway stations, administrative offices, banks, hospitals, schools and other units for auxiliary business handling and teaching experiment tasks. [0003] Among them, some multimedia terminals have a lifting function. The display or human-computer interaction panel is assembled on the lifting panel. When in use, the panel is raised for various operations. When storing, the panel is lowered to reduce space occupation and protect screen or operation panel. [0004] However, with the development and popularization of LCD technology, manufacturers have begun to increase the size of displays and human-computer interaction panels to improve user experienc...

AI Technical Summary

Problems solved by technology

[0005] For this reason, it is necessary to provide a panel lifting device to solve the problem that the motor occupies the panel lifting space in the prior art, which makes it difficult to optimize the structure of the multimedia terminal in the direction of miniaturization and increase in the size of the display screen.
