Embodiment
Below with reference to figure and specific implementation process the utility model is described in further details:
Embodiment 1:
As Fig. 1, a kind of multifunction reinforcing display device is characterized in that liquid crystal board is arranged in the housing, and the front-end and back-end of housing are respectively arranged with front panel and rear panel; Between liquid crystal board and front panel, be provided with shield glass; The plate inside surface is provided with power panel and control panel in the back.
In the present embodiment to the consolidation process of liquid crystal board most importantly at the processing of its anti-vibrating and impact ability.Usually four mounting holes and the casing by liquid crystal board is rigidly connected between liquid crystal board and the casing, under the duty, in case display system recurring structure resonance will directly have influence on the electric property of display module of display and the stability of system, even cause system to damage.Analyze and find that the principal element that influences reinforcement type liquid crystal board anti-vibrating and impact performance has: 1) the direction rigidity that liquid crystal board is vertical with screen is very poor; 2) fluorescent tube length and tube wall are very thin, and be therefore quite fragile; 3) line is loosening because of vibration is easy to generate between integrated circuit board, influences display quality.Under the condition that dynamic excitation improves, keep deformation constant, can pass through vibration reducing measure on the one hand, reduce the excitation transport, decay encourages, thereby reduces its actual excitation and limit its distortion.Can pass through additional stiffness on the other hand, improve natural frequency, make destination object under the situation that excitation increases, part or even most energy are shared on additional structure, thereby effectively reduce the actual excitation energy of destination object, can effectively reduce its distortion like this.The problem proposition solution that is primarily aimed at the liquid crystal board poor rigidity below is as follows: one, Vibration Absorption Designing will reduce the influence of dynamic excitation to display, is a kind of very effective vibration reducing measure by adopting vibration damper to reduce excitation.The vibration damper that adopts in this example has characteristics such as the big damping of intermediate frequency, three direction rigidity approximately equals, and is strong to the dynamic condition adaptability of rugged surroundings, and stronger adaptive capacity to environment is arranged; Its two, the most direct method of structure resonance is avoided in laminated glass design, improves the natural frequency of display module exactly.Utilization finite element analysis, and utilization large scale structure analysis software NASTRAN, SAP or ANSYS are carried out static analysis and optimal design to whole reinforcing liquid crystal board, under the satisfactory condition of weight, to conduct oneself with dignity as load, as objective function, seek max architecture rigidity with natural frequency.On the basis of the laminated glass structure patent of U.S. White company, by optimal design, analysis, in conjunction with the structural behaviour of self, through using the optics glue on liquid crystal board in the glass behind the tempering after the special technological process processing, liquid crystal board is realized initiatively reinforcing the natural frequency that makes structure arrive raising, the stress distribution of structure is tending towards evenly rationally, weak link is strengthened.
