As we all know, the biggest difference in the use of notebook computers and desktop computers is that notebook computers have the characteristics of being portable, which allows consumers to escape the restriction that they can only work at a desk , also because the notebook computer is a kind of electrical device that can be carried and used. Relatively, in addition to its functional specifications and grades for consumers to choose, its appearance design is one of the key points for consumers to choose.

Furthermore, the appearance of a notebook computer basically includes two main parts, the body and the LCD screen. The LCD screen can be folded and closed relative to the body, so the back cover of the LCD screen becomes the focus of the overall appearance design. In addition, the back cover of the LCD screen is easily scratched and stained, making the design of the back cover replaceable gradually becoming the demand of consumers.

However, in the past, the assembly structure of the back cover of the LCD screen is mostly shown in Figure 1. The liquid crystal module 1, the fixing frame 2, the front cover 3 and the back cover 4 in the LCD screen are mainly locked together by screws 5. When the user or When the manufacturer needs to disassemble and replace the back cover, he must repeatedly remove and install the screws, which not only complicates the assembly steps of the LCD screen, but also reduces the convenience for consumers to replace the back cover by themselves.

Utility model content

Detailed ways

The features of the utility model can be clearly understood by referring to the drawings of the utility model and the detailed description of the embodiments.

The back cover assembly structure of the liquid crystal screen of the present invention includes: a liquid crystal module 1, a fixing frame 2, a front cover 3 and a back cover 4; please refer to Figure 2 to Figure 4 at the same time; Figure 2 is the liquid crystal module The exploded view of the structure with the fixed frame (assembly step one); Fig. 3 is the structural exploded view of the front cover and the fixed frame (assembly step two); Fig. 4 is the structural exploded view of the back cover and the front cover (assembly step three); wherein :

The fixing frame 2 is used to fix the liquid crystal module 1, and the periphery of the fixing frame 2 and the front cover 3 is provided with a plurality of fixing components 6, as shown in the figure, each fixing component 6 is provided with a plurality of fixing components 6 at the front cover 3 A first hook 62, in addition, a plurality of perforations 63 can be further provided on the periphery, and each fastening component 6 is also provided with a first button hole 61 corresponding to the first hook 62 on the fixed frame 2, Furthermore, a screw hole 64 corresponding to the through hole 63 and a plurality of screws 5 capable of locking the through hole 63 and the screw hole 64 can be further provided on the periphery of the fixing frame 2 .

The front cover 3 and the back cover 4 are further provided with a plurality of fastening components 7, and the fastening components 7 include a second button hole 71, a second hook 72 corresponding to the second button hole 71, a third The hook 73 and the third button hole 74 corresponding to the third hook 73 . Wherein, the second button hole 71 is disposed on one joint edge 41 of the back cover 4 ; and the second hook 72 is disposed on a corresponding side of the front cover 3 and the second button hole 71 .

In addition, the third hook 73 is respectively arranged on the three joint edges 42, 43, 44 of the back cover 4, and each joint edge 42, 43, 44 is different from the joint edge 41 provided by the second button hole 71, and The third button hole 74 is provided on the corresponding side of the front cover 3 and each joint edge 42 , 43 , 44 .
