Installation shell with cushioning structure and full-lamination liquid crystal display instrument

Abstract

The invention discloses an installation shell with a cushioning structure and a full-lamination liquid crystal display instrument. The installation shell with the cushioning structure comprises a rearcover for connecting a support frame and an upper cover for installing a part to be assembled; the rear cover and the upper cover can be sealed and combined into one body; and the rear cover is provided with a structure comprising a first cushioning mechanism for being connected with the support frame and / or second cushioning mechanisms cooperatively formed on the rear cover and the upper cover.The cushioning mechanisms are arranged on the rear cover and / or the upper cover respectively, so that at least one cushioning is carried out in the process that vibration is transferred to the rear cover from an instrument installation support and then is transferred to the upper cover, and vibration force born by the part to be assembled is in a safe range; moreover, according to the structure, the quantity of the cushioning structures can be selected according to different application occasions, the application is flexible, and the scope of application is wide; and therefore, technical assurance is provided for carrying out full lamination on a liquid crystal display module and an organic glass cover plate on an engineering machinery instrument.

Description

technical field [0001] The invention relates to the field of construction machinery instruments, in particular to an installation shell with a shock-absorbing structure and a full-fit liquid crystal display instrument. Background technique [0002] Construction machinery instruments are tools used to display equipment operating status and / or various operating parameters. They have various types and functions, and are widely used in various industries. [0003] as attached figure 1 The engineering machinery instrument shown with a liquid crystal display includes an upper cover 02 and a rear cover 04 combined into one, the upper cover 02 cooperates with the pressure plate 05 to form a card slot for placing the liquid crystal display module 03, and the liquid crystal display module 03 is reduced by the liquid crystal. The shock sleeve 06 is fixed in the card slot, and the upper cover 02 is provided with a plexiglass cover plate 01 keeping a gap with the liquid crystal display ...

AI Technical Summary

Problems solved by technology

[0004] In this structure, the liquid crystal display module 03 and the plexiglass cover 01 are not completely bonded together, and there is a large gap between the liquid crystal display module 03 and the plexiglass cover 01, and there is gas in the gap, which causes the instrument liquid crystal Display color saturation, interface anti-Newton ring, viewing angle, anti-vertigo effect, etc. are relatively poor, resulting in poor display effect of the instrument. At the same time, the above structure also has the problem of relatively poor dustproof and waterproof effect

[0005] Therefore, it is imperative to fully bond the liquid crystal display module 03 and the plexiglass cover plate 01 to solve the above-mentioned problem of poor display effect. The liquid crystal display module is easily damaged due to vibration, which leads to the need for construction machinery instruments to have sufficient shock-absorbing structures to prevent the impact of vibration on the liquid crystal display module

[0006] And attached figure 1 In terms of the vibration transmission process, the vibration is firstly transmitted from the instrument mounting bracket to the back cover, and then through the back cover to the upper cover, and the upper cover is transmitted to the liquid crystal shock absorbing sleeve through itself and the pressure plate for buffering and shock absorption. Liquid crystal display module, the vibration is mainly buffered by the liquid crystal shock absorber, and the liquid crystal shock absorber is used to reduce the impact of vibration on the liquid crystal display module, but the attached figure 1 The structure of the liquid crystal display module 03 cannot meet the anti-seismic requirements of the liquid crystal display module 03 and the plexiglass cover plate 01.

[0007] This is because, after using the full bonding process, the liquid crystal display module and the plexiglass cover are glued together, and the plexiglass cover is connected to the upper cover at the same time, and the vibration of the upper cover is directly transmitted through the plexiglass cover without buffering For the liquid crystal display module, at this time, the liquid crystal shock absorber 06 can not exert the shock absorption effect at all, and there is no effective shock absorption measure to protect the liquid crystal display module
