Abstract

The liquid crystal module assembling structure and method is used in fixing liquid crystal module and has two casings set separately on two sides of the liquid crystal module. The first shell has an assembling column with one end fixed on the shell and the other end having radial flange, the center has an axial opening, and the axial opening radiates out at least one groove to divide the assembling column into at least two parts. The second shell is provided with a fixed column. When the two shells are assembled, the assembly column of the first shell penetrates through the fixing hole of the liquid crystal module, and then the fixing column of the second shell is inserted into the axial opening hole to prop open the assembly column so that the radial flange buckles the liquid crystal module.

Description

Liquid crystal module assembly structure and method

technical field

The invention relates to an assembly structure and method, in particular to a liquid crystal module assembly structure and method.

Background technique

FIG. 1 is a perspective view of the structure of a liquid crystal module inside a notebook computer or a liquid crystal screen in the prior art. In the figure, the liquid crystal module 100 is covered and fixed between the upper shell 110 and the lower shell 120 of the shell structure.

The method of assembly is usually screw fixing. For example, in FIG. 1 , there are four fixing holes 102 on the liquid crystal module 100, which are locked to the upper case 110 with screws 104, and then the lower case 120 is also locked together with the upper case 110 through the fixing holes 122 and screws 124. , the liquid crystal module 100 is sandwiched between the upper case 110 and the lower case 120 in a sandwich-like manner.

However, the disadvantage of the above-mentioned screw fixing method is that it needs to tap the screw holes in the upper casing 110, and the assembly process needs to consume manpower in the step of screw locking, and more importantly, it is a waste of time. In the production line where every second counts , a more efficient assembly method is really needed.

In summary, the prior art liquid crystal module assembly structure and method obviously have inconveniences and defects in actual use, so it is necessary to improve them.

Detailed ways

The implementation of the present invention is described below with an embodiment, and the device of the present invention can be applied to various related assembly methods.

The feature of the present invention is that the fixing of the liquid crystal module described in the background of the invention can be completed without using screw locking. In addition to the assembly and fixing of the liquid crystal module during the assembly process of the notebook computer or the liquid crystal screen, there will also be fixing of the shell, so the present invention provides an assembly structure without screw locking, which is used to save the cost and time of liquid crystal module assembly . As shown in FIG. 2 , it is an exploded perspective view of a liquid crystal module in a preferred embodiment of the present invention. The liquid crystal module 200 in the figure also has the fixing hole 202 , and the difference from the prior art is that the upper housing 210 has the assembly column 212 , and the lower housing 220 has the fixing column 224 . When the liquid crystal module 200, the upper casing 210 and the lower casing 220 are assembled, the assembly column 212 of the upper casing 210 passes through the fixing hole 202 of the liquid crystal module 200, and then the combination of the fixing column 224 of the lower casing 220 and the assembly column 212 is completed Assemble. How to combine the fixing column 224 and the assembly column 212 will be described below through an embodiment.

3A and 3B are schematic cross-sectional views of the fixing holes, the fixing posts and the assembly posts when the liquid crystal module is assembled according to a preferred embodiment of the present invention. As shown in FIG. 3A , the upper housing 210 has an assembly column 212 , wherein a flange 216 is formed at the front end, and an axial opening 214 is formed at the center. The lower housing 220 has a tapered fixing post 224 , the function of which is to insert into the axial opening 214 of the assembling post 212 to spread the assembling post 212 . When the liquid crystal module 200, the upper housing 210 and the lower housing 220 are assembled, the upper housing 210 passes through the fixing hole 202 of the liquid crystal module 200, and then the fixing column 224 of the lower housing 220 is inserted into the axial opening 214 of the assembly column 212 , to expand the assembly column 212. Therefore, the flange 216 of the expanded assembly column 212 will buckle the sheet metal around the fixing hole 202 , so that the liquid crystal module 200 is fixed between the upper and lower casings.

3C is a schematic cross-sectional view of the liquid crystal module fixing holes, fixing posts and assembly posts in another preferred embodiment of the present invention. In this embodiment, the upper housing 210 has an assembly column 212, which is different from the previous embodiment in that the front end of the assembly column 212 does not have a flange, but the center of the assembly column 212 has an axial opening 214, and the The axial opening 214 has a friction-increasing structure 213 inside. This structure can use a rough surface material (such as abrasive cloth for surface treatment) plus a friction-increasing structure (such as a thread structure). The lower casing 220 has a fixing column 224, which is used for inserting into the axial opening 214 of the assembly column 212, wherein the fixing column 224 can be tapered or cylindrical. When the liquid crystal module 200, the upper housing 210 and the lower housing 220 are assembled, the upper housing 210 passes through the fixing hole 202 of the liquid crystal module 200, and then the fixing column 224 of the lower housing 220 is inserted into the axial opening 214 of the assembly column 212 , the friction-increasing structure in the assembly column 212 can be used to buckle the fixing column 224 . In order not to scratch the liquid crystal module 200 when the upper case 210 and the lower case 220 are assembled, a bump 215 can be added on the side of the upper case 210 and the lower case 220 close to the liquid crystal module 200, and the bump 215 can Made of rubber or other elastic material.

It should be noted that the structural design of the assembly column 212, as shown in Figures 4A, 4B, 4C, 4D and 4E are schematic diagrams of the detailed structure of the assembly column of the present invention. Figure 4A is a cross-sectional view of the assembly column; Figures 4B, 4C, 4D and 4E are side views of different designs of the assembly column, in which the assembly column 212 has at least one groove 218 radiating outward from the axial opening 214, Make the assembly column 212 easy to be stretched. For example, Figure 4B is divided into 3 parts; Figure 4C is divided into 4 parts; Figure 4D is divided into 2 parts, of course, it can be divided into more parts as required. FIG. 4E shows an assembly column without a groove. The material of the assembly column needs to be elastic or ductile. When the fixing column 224 is inserted into the axial opening 214, the elastic or ductile assembly column is stretched, and the flange 216 It will buckle the sheet metal around the fixing hole.

The above liquid crystal module assembly structure of the present invention may fall off relatively easily because no screws are used for locking. Therefore, this structure is only applicable to the liquid crystal module and there is another shell to cover and fix the assembled structure.

It can be known from the above preferred embodiments of the present invention that the application of the present invention has the advantage of being able to assemble liquid crystal modules without using screws, and can reduce the assembly time during mass production.

It can be understood that, for those of ordinary skill in the art, various other corresponding changes and modifications can be made according to the technical scheme and technical concept of the present invention, and all these changes and modifications should belong to the appended rights of the present invention. the scope of protection required.
