Description

Technical Field

[0001] This utility model relates to a computer component, and more particularly to a laptop casing component. Background Technology

[0002] A logo, or logotype, refers to an emblem or trademark. Currently, logos on the back cover (A-shell) of laptop displays are often achieved through labeling, engraving, and printing. This method is costly, has limited functionality, is not eye-catching, and has a narrow range of applications. A utility model patent with publication number CN 204130082 U discloses a display device with an opening on the back cover. A logo element is located at the opening. The logo element is made of transparent material, and light emitted from the light-emitting unit passes through the logo element to form a bright trademark. The logo element has two transparent material layers, with a pattern layer located between the two transparent material layers. In this design, the logo element is connected to the back cover by transparent adhesive, and the back of the logo element protrudes relative to the back cover, occupying space for other components and failing to meet the requirements of thin and light laptops. Furthermore, the pattern layer is difficult to process. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a notebook casing component that helps to reduce thickness.

[0004] Technical solution: The present invention provides a notebook shell assembly, including an A-shell and a light guide sheet. The front of the light guide sheet is provided with a protrusion for forming a logo graphic, the A-shell is provided with a through hole for the protrusion to pass through, and the inner side of the A-shell is provided with a groove for embedding the light guide sheet.

[0005] Preferably, the protrusions enclose a closed shape, and the back of the light guide sheet is provided with a light-shielding layer to block light from passing through the center of the closed shape.

[0006] Preferably, the groove depth is 0.4 to 0.6 mm.

[0007] Preferably, the inner wall of the A shell is provided with easy-pull adhesive on both sides for connecting the back of the screen.

[0008] Preferably, foam for supporting the screen is provided on both sides of the inner wall of the A shell.

[0009] Preferably, the bottom inner side of the A-shell is provided with a hinge for connecting the keyboard.

[0010] Preferably, the opening of shell A is provided with shell B for constraining the perimeter of the screen.

[0011] Beneficial effects: Compared with the prior art, this utility model has the following advantages: 1. Reduced thickness: A groove is set on the A shell, and the light guide sheet is embedded in the groove. The light guide sheet embedded in the shell takes up almost no space, and the gap between the screen and the shell is already sufficient, which is suitable for thin laptops. At the same time, the groove helps to increase the connection strength between the light guide sheet and the back plate; 2. Simplified process and reduced cost: The light guide sheet can be integrally molded by injection molding, and a light-shielding layer is set on the back of the light guide sheet. The light-shielding layer can be made by screen printing, which helps to simplify the process and reduce costs; 3. It can realize the function of different logos illuminating; 4. The logo is made of plastic material, and there is no problem of generating additional heat when illuminating. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 7The laptop casing assembly includes an A-shell 1 and a light guide 3. The front of the light guide 3 has a protrusion 31 for forming a logo graphic. The A-shell 1 has a through hole 11 for the protrusion 31 to pass through. The inner side of the A-shell 1 has a groove 12 that matches the outer shape of the light guide 3 and is used to embed the light guide 3. The groove depth is 0.4-0.6mm, specifically 0.5mm. The left and right sides of the inner wall of the A-shell 1 have easy-pull adhesive 13 for connecting the back of the screen 4. The upper and lower sides of the inner wall of the A-shell 1 have foam 14 for supporting the screen 4. The bottom of the inner side of the A-shell 1 has a hinge that connects the A-shell to the keyboard (not shown). The hinge has a hinge cover. The opening of the A-shell 1 has a B-shell 3 for constraining the screen 4.

[0021] Taking the “NARI” pattern as an example, the graphic formed by the protrusions 31 includes straight lines, semi-open shapes, and closed shapes 32. The center of the closed shape 32 cannot be blocked by the shell 1. In order to shield this part of the light to form a specific pattern, a light-shielding layer 33 is provided on the back of the light guide 3. The light-shielding layer 33 is used to block the light and prevent the light from passing through the center of the closed shape 32.

[0022] During processing, firstly, a through hole 11 matching the outer shape of the "NARI" logo is milled in the middle of the A shell 1 using CNC. Then, a 0.5mm groove 12 is milled on the inner side of the A shell 1. Taking the rectangular light guide plate 3 as an example, the shape of the groove 12 is consistent with the outer shape of the light guide plate 3, which is also rectangular. Subsequently, AB glue is applied to the groove 12, and then the light guide plate 3 is embedded into the groove 12 and pressed and fixed. 0.5mm thick easy-pull adhesive 13 is attached to the left and right sides of the inner wall of the A shell 1, and 0.4mm thick EVA foam 14 is attached to the top and bottom sides. The protective film of the easy-pull adhesive 13 is peeled off, and the screen 4 is attached to the easy-pull adhesive 13 of the A shell 1 and pressed. Finally, the B shell 3 and the camera image are attached to the A shell 1 and the screen 4, and the hinge cover is assembled, which completes the assembly.

[0023] When in use, the light guide plate 3 itself does not have a built-in LED light source. Instead, it uses the backlight of the built-in display screen inside the casing as the light source. When the computer is turned on, the screen backlight shines on the light guide plate 3 made of light-transmitting material to make the logo light up. The brightness of the logo can be adjusted synchronously with the brightness of the computer screen. When the computer is turned off or in sleep mode, the logo will also turn off and not light up.
