Embodiment
Fig. 1 is the structural representation of the vibration damping ruggedized construction of a kind of liquid crystal screen component of the present invention, and the reinforcing of liquid crystal screen component is made up of movement support 1, securing supports and locating part 10.Movement support 1 fixes liquid crystal screen component, and provides the friction area of band limit function in order to be connected with securing supports.Securing supports is made up of web member 8 and friction member 9, and web member 8 is fixed on external structure, as panel, framework etc., friction member 9 is fixed on web member 8 by adjusting bolt 11, and and distance between web member 8 can regulate, for providing the friction force between securing supports friction area.Position limiting structure is used for the distance between constrained motion support member 1 and web member 8, in order to ensure that the pressure between friction member 9 and securing supports is particular value.
Fixing by friction between movement support 1 and securing supports, the acting force that liquid crystal screen component is moved along the normal direction of display panel is provided by friction force, and limits liquid crystal screen component and outside relative displacement by the limit function of movement support 1 frictional groove 6.
Web member 8 is provided with the web member pilot hole 81 of vertical liquid crystal screen place in-plane, movement support 1 is provided with the support member pilot hole 7 of vertical liquid crystal screen place in-plane, locating part 10 two ends are provided with limited post 101, limited post 101 insert web member pilot hole 81 and support member pilot hole 7 and constrained motion support member 1 and web member 8 liquid crystal display relative motion planar.It is designed to constrained motion support member 1 and securing supports liquid crystal panel 5 relative motion planar, but do not limit the relative motion perpendicular to liquid crystal panel 5 direction.Its dimensional requirement, when temperature variation, can ensure the maintain constant pressure between friction member 9 and movement support 1.
Web member 8 is connected with external structure by modes such as welding, bolt, glue classes simultaneously.The vibration being parallel to liquid crystal panel 5 direction can be directly delivered on screen assembly by locating part 10, can not have influence on the pressure between friction member 9 and movement support 1.The thermal deformation that temperature causes can be eliminated by the size designing locating part 10 impact of pressure between friction member 9 and movement support 1.
When being subject to impacting:
1, when the vibration perpendicular to liquid crystal panel 5 direction or when impacting less, because the effect of friction force can transfer vibrations to screen assembly, by rigidity and the damping restrained deformation of screen assembly self.
2, when the vibration perpendicular to liquid crystal panel 5 direction or when impacting larger, because the friction force that can provide is limited, relative motion is there will be between friction member 9 and movement support 1, make larger vibration or impact to transmit, the vibration of guarantee effect in liquid crystal screen component, impulsive force are less, prevent liquid crystal panel 5 from occurring light leakage phenomena.
Frictional groove 6 possesses limit function, can ensure that liquid crystal screen component can not be separated with structure under strong vibration is impacted.Adjusting bolt 11 can adjust contact between friction member 9 and movement support 1, and then adjustment allows the maximum force of transmission, can make to be applicable to different vibration environments with a liquid crystal screen component.
After adopting above-mentioned structure, anti-vibration, the impact capacity of liquid crystal screen component can be improved when not changing liquid crystal screen component, eliminating the light leakage phenomena of liquid crystal panel 5 under strong vibration.Can lead to simultaneously and regulate contact to make to be applicable to different vibrations, shock environment with a liquid crystal screen component, increase the versatility of liquid crystal screen component.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
