Description

Outdoor anti-impact liquid crystal display screen

Technical Field

The utility model relates to the technical field of liquid crystal display screens, in particular to an outdoor impact-resistant liquid crystal display screen.

Background

Liquid Crystal Displays (LCDs) are well known for use in digital watches and one type of display for many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. When current is passed through the liquid, the crystals will rearrange so that light cannot pass through them. Therefore, the liquid crystal display screen is relatively fragile and is easily damaged by the vibration generated by collision.

At present, liquid crystal display puts the use in the open air, it is big because of the flow of people, protect the accident of some collisions that take place irregularly, therefore, the effect of crashproof will be considered usually to open air liquid crystal display, the liquid crystal display that the market is current adopts the shell to seal mostly, and keep the buffering clearance between face-piece and liquid crystal display module, and then reach the effect of crashproof, and simultaneously, can select to pack some bolsters such as foam or sponge here a bit, in order to reach the effect that improves the protection, but its bolster of filling is real piece, its buffering effect is limited, so when in-service use, the effect is not good.

Detailed Description

The embodiments of the utility model will be described in detail below with reference to the drawings, but the utility model can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1 to 3, the outdoor impact-proof liquid crystal display that this embodiment provided, including casing 1 and liquid crystal display module 2, casing 1's preceding terminal surface is formed with the accent 3 that is used for laying liquid crystal display module 2, the inner wall avris of accent 3 evenly is provided with lays station 4, every place and has placed flexible glue piece 5 in the station 4, flexible glue piece 5 has seted up logical chamber 6, the end of flexible glue piece 5 is provided with and is "L" type take and put mouth 7, liquid crystal display module 2's periphery is through the cladding of frame 8, frame 8 is laid and is put mouth 7 department and form the extrusion top with flexible glue piece 5 and touch, casing 1 is located accent 3 department and extends and has lid portion 9, it has transparent PC board 10 to press from both sides between lid portion 9 and the frame 8, be provided with damping ball 11 between transparent PC board 10 and the frame 8.

This embodiment is to how the theory explanation is carried out to protecting against shock, its transparent PC board 10 and the portion 9 that closes carry out the sealed combination with lid, make the accent form airtight cavity, can set up sealing rubber ring 12 between portion 9 and the transparent PC board 10 of closing, in order to be used for reaching positive waterproof effect, and the LCD module 2 that is located the accent 3 then carries out cladding formula equipment through frame 8, play LCD module 2 self stable in structure, and set up damping ball 11 between frame 8 and the transparent PC board 10, thereby when the positive impact takes place, the impact force just can be transmitted for transparent PC board 10 through portion 9 that closes, later through damping ball 11, and then transmit for frame 8, and once the impact force transmits damping ball 11 department, just can cushion through damping ball 11, thereby just can attenuate the impact force, play the guard action to the face impact. When the impact force happens from the side edge, the impact force is transmitted to the soft rubber block 5 from the shell 1 and then transmitted to the frame 8, once the impact force is transmitted to the soft rubber block 5, the impact force can be buffered, the soft rubber block 5 is provided with the through cavity 6, the buffering capacity of the soft rubber block 5 can be further improved through the design of the through cavity 6, the buffering of the impact force is more remarkable, and therefore the impact on the side surface can be prevented. And the liquid crystal display screen in the open air is mainly that the front and the side can take place unnecessary impact (object collision), consequently, through the buffering to front and side impact force, alright play more effective guard action.

Further, this embodiment the casing 1 is provided with two first separate chambeies 13 and the second separate chamber 14 that are independent and parallel to each other for the back of accent 3, install radiating block 15 in first separate chamber 13, radiating block 15 and the laminating of liquid crystal display module 2, radiating block 15's fin exposes in second separate chamber 14, the casing 1 back is provided with a plurality of louvre 16, louvre 16 separates chamber 14 intercommunication with the second. The heat dissipation of liquid crystal display module assembly 2 is ensured to its radiating block 15's setting, and the design of first dividing a chamber 13 and second dividing a chamber 14 is then isolated with the convection current chamber that the external world is connected with inside, avoid water to enter into inside, because the design of louvre 16 is under bad weather, the rainwater probably drifts into from louvre 16, therefore, even the rainwater gets into the back, can directly not enter into the position at liquid crystal display module assembly 2 place yet, in addition, the design of first dividing a chamber 13 and second dividing a chamber 14, also to the rear to a certain extent, there is corresponding buffering protection impact force yet, in case the impact takes place promptly, the destructive deformation of casing 1 can be convenient for in the design of second dividing a chamber 14, buffer impact force.

Further, since rainwater may enter the second compartment 14 as described above, in order to prevent rainwater from remaining, the bottom of the housing 1 of the present embodiment is provided with a drain port 17, and the drain port 17 communicates with the second compartment 14, so that rainwater may be discharged through the drain port even after entering the second compartment 14.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
