Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in detail.Following example will assist in those skilled in the art and are further appreciated by this utility model, but limit this utility model the most in any form.It should be pointed out that, to those skilled in the art, without departing from the concept of the premise utility, it is also possible to make some changes and improvements.These broadly fall into protection domain of the present utility model.
As shown in Figure 1 and Figure 2, this utility model liquid crystal refrigerator door structure is to be made up of doorframe 16, LCD MODULE 18, front glass sheet 14, rear glass sheet 15 and aluminum strip 17；Front glass sheet 14 and rear glass sheet 15 are disposed in doorframe 16, and LCD MODULE 18 and aluminum strip 17 are clipped between front glass sheet 14 and rear glass sheet 15 respectively.
LCD MODULE 18 includes the framework of the hollow structure of one end open, and framework is made up of the backboard 1 binded by fluid sealant 13 and fixing housing 2, and backboard 1 and fixing housing 2 are aluminium, in the situation of proof strength, and convenient heat radiation.
Center is arranged in the chamber in framework, concrete, and the base 7 of center is arranged on the bottom of chamber, and one end of the installation portion 8 of center is connected with base 7, and the other end of installation portion 8 is perpendicular to base 7 and the direction away from base 7 extends.Simultaneously, installation portion 8, base 7 form the first installing space with the side inwall (inwall of backboard 1) of framework, and installation portion 8 forms the second installing space with the bottom surface (bottom surface of fixing housing 2) of the opposite side inwall of framework (inwall of fixing housing 2) and framework.
During installation, LED lamp bar 3 is placed on base 7, namely in the first installing space, being connected by heat conductive pad 10 between LED lamp bar 3 with base 7, in the present embodiment, heat conductive pad 10 is the heat conduction adhesive tape choosing 3M, heat conduction adhesive tape is in the case of heat, temperature is the highest, stickiness is the biggest, utilizes the characteristic that this stickiness and temperature are the most proportional just, LED lamp bar 3 can be played good fixation.The part of light guide plate 4 stretches in the first installing space, is arranged at the top of LED lamp bar 3, arranges sealing gasket 11 between the side inwall (inwall of backboard 1) of light guide plate 4 and framework.Light is injected from the side of light guide plate 4 by LED lamp bar 3 as light source, relends and is got on liquid-crystalline glasses 6 spaced with light guide plate 4 by light by the guide-lighting micro structure 5 on light guide plate 4.Meanwhile, between light guide plate 4 and installation portion 8, it is provided with snoot 9, plays the effect of optically focused, reduce scattering of light, improve the efficiency of light.
Additionally on one side, liquid-crystalline glasses 6 is arranged in the second installing space, and arranges sealing gasket 11 between the opposite side inwall (inwall of fixing housing 2) of framework.Liquid-crystalline glasses 6 is vertically set on the mounting platform on installation portion 8 top, keeps the parastate with light guide plate 4, and gap between the two is maintained at 1 millimeter～2 millimeters, work as excesssive gap, such as: during more than 5 millimeters, the volume that may result in assembling is excessive, directly affects the assembling of whole module.
Owing to liquid-crystalline glasses 6 is vertically set on the mounting platform on installation portion 8 top, say, that liquid-crystalline glasses 6 is stood the most deeply into the bosom to framework.So, liquid-crystalline glasses 6, installation portion 8, the inwall (inwall of fixing housing 2) of framework form a protection chamber 12 with the bottom surface of framework (bottom surface of fixing housing 2), and are filled with noble gas in protection chamber 12, play the effect of protection.
As it is shown on figure 3, first assemble LCD MODULE 18, being first according to the dimensional requirement of semi-transparent LCD MODULE 18, process or choose light guide plate 4, size slightly larger than LCDs according to design, is chosen the corresponding LED lamp bar of light guide plate 43 and LED and is driven.Choose the snoot 9 of corresponding LED lamp bar 3 and choose heat conductive pad 10 (heat conductive pad 10 is the heat conduction adhesive tape choosing 3M).Process corresponding aluminium alloy structure framework (backboard 1 and fixing housing 2), LED lamp bar 3 and snoot 9 are installed together by heat conduction adhesive tape, snoot 9 and light guide plate 4 are fixedly mounted on center, and reserve the position (generally 2～4 lead-in wires) of LED power cabling.Liquid-crystalline glasses 6 is arranged on and fixes on LED lamp bar 3 and light guide plate 4, and the logic card of liquid-crystalline glasses 6 is installed, install need to be in view of minimizing herein, the space allowing logic card take is the fewest (making the gap between light guide plate 4 and liquid-crystalline glasses 6 be maintained at 1 millimeter～2 millimeters), make to accomplish narrower framework when subsequent design transparent liquid crystal doorframe, finally lock whole framework with screw, seal whole semi-transparent structure simultaneously.
After completing the composition of dress LCD MODULE 18, LCD MODULE 18 is placed on the front glass sheet 14 of refrigerator, positioner is utilized to fix, so also have door is holded up when and effectively support, the aluminum strip 17 of conventional seals refrigerator door is put in the untouched region of LCD MODULE 18, namely in the position of the logic card side of LCD MODULE 18, wherein with desiccant in aluminum strip 17.Then by traditional sealing silica gel, front glass sheet 14 and rear glass sheet 15 are sealed to hollow, insert suitable noble gas simultaneously.Again the double glazing mechanism of this good seal is installed in the doorframe 16 of refrigerator, the LED power line of LCD MODULE 18 and holding wire all pass through the framework of doorframe 16 and are hingedly connected in the main body casing of refrigerator, and the power supply that the driving of LCD MODULE 18 and LED drive all is placed into refrigerator body interior.
Above specific embodiment of the utility model is described.It is to be appreciated that this utility model is not limited to above-mentioned particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or revise, and this has no effect on flesh and blood of the present utility model.In the case of not conflicting, the feature in embodiments herein and embodiment can arbitrarily be mutually combined.
