These embodiments are provided herein to make the disclosure of this application more complete and to fully convey the concept of the present application to those skilled in the art.

[0022] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] like Figures 1-2As shown in the embodiment of this application, a ruggedized laptop computer includes a keyboard assembly 1, a mid-frame 2, a bottom plate 3, a front cover 4, and a screen assembly 5. The keyboard assembly 1 is mounted on the top of the mid-frame 2. The top four corners of the mid-frame 2 are fitted with first corner protectors 6, and the bottom four corners of the mid-frame 2 are fitted with second corner protectors 7. The mid-frame 2 includes four profiles 21 and four connectors 22. The four profiles 21 are enclosed to form a rectangle. The connectors 22 are detachably connected between two adjacent profiles 21. Optionally, the connectors 22 are connected to the profiles 21 by screws, so that the four profiles 21 can be spliced ​​together to form a rectangular mid-frame 2. The bottom plate 3 is mounted on the bottom of the mid-frame 2. One side of the front cover 4 is hinged to one side of the keyboard assembly 1, and the four corners of the front cover 4 are fitted with third corner protectors 8. The screen assembly 5 is mounted on the front cover 4. The mid-frame 2, the bottom plate 3, and the front cover 4 are made of aluminum-magnesium alloy.

[0024] By setting the first corner protector 6 to cover the top four corners of the middle frame 2, the second corner protector 7 to cover the bottom four corners of the middle frame 2, and the third corner protector 8 to cover the four corners of the front cover 4, the first corner protector 6, the second corner protector 7, and the third corner protector 8 can absorb the impact of the fall when the laptop is accidentally dropped while the lid is closed. This provides good drop resistance and prevents the four corners of the laptop from being damaged by bumps. When the laptop is open, the first corner protector 6, the second corner protector 7, and the third corner protector 8 can also completely cover the corners of the laptop, preventing damage from bumps to the corners. The middle frame 2, the bottom plate 3, and the front cover 4 are all protected by these corner protectors. The cover 4 is made of aluminum-magnesium alloy, which features high strength, lightweight, corrosion resistance, shock resistance, and drop resistance. It enhances the overall structural rigidity of the laptop shell, making it less prone to deformation when subjected to external impacts. It is durable and can operate efficiently for a long time in harsh environments such as industrial, military, and field exploration. The middle frame 2 is made of profiles 21 spliced ​​together. Profiles 21 and connectors 22 can be formed separately and processed in small pieces. Compared with the one-piece molded middle frame 2, it reduces material waste, thereby reducing material costs and shortening the processing cycle of a single workpiece. The processing time is short, and it can be processed and spliced ​​using a small CNC machine tool.

[0025] Optionally, a snap-fit ​​plate 41 is vertically fixed to the front side wall of the cover 4. The inner side of the snap-fit ​​plate 41 is provided with a first snap-fit ​​protrusion (not shown in the figure), which can be made of an elastic material. The front side wall of the middle frame 2 is provided with a second snap-fit ​​protrusion 9 that matches the first snap-fit ​​protrusion. When the cover 4 is rotated downward, the first snap-fit ​​protrusion on the snap-fit ​​plate 41 contacts the second snap-fit ​​protrusion 9 on the middle frame 2, and the first snap-fit ​​protrusion undergoes elastic deformation until the screen assembly 5 and the keyboard assembly 1 are closed. At this point, the first snap-fit ​​protrusion passes over the second snap-fit ​​protrusion 9 and abuts against the lower part of the second snap-fit ​​protrusion 9, thereby ensuring the secure closure of the cover 4.

[0026] Specifically, a base plate 100 is installed inside the middle frame 2. A motherboard 200, a battery 300, a battery management board 400, and a speaker 500 are installed on the base plate 100. The base plate 100 is shockproof and can prevent the motherboard 200, battery 300 and other components from being impacted. The base plate 100 has a pre-set expansion area where hardware devices such as hard drives and optical drives can be selectively installed.

[0027] The middle frame 2 has a DC power interface 10 and several evenly distributed side air vents 20 on the side wall near the motherboard 200.

[0028] The middle frame 2 has a first expansion I / O port 30 and a first side cover 40 on one side wall near the expansion area. The first side cover 40 matches the first expansion I / O port 30, and the lower end of the first side cover 40 is rotatably connected to the lower part of the first expansion I / O port 30. The rear side wall of the middle frame 2 has a second expansion I / O port 50 and a second side cover 60 corresponding to the expansion area. It also has a motherboard I / O port 70 and a third side cover 80 corresponding to the motherboard 200. The second side cover 60 matches the second expansion I / O port 50, and the lower end of the second side cover 60 is rotatably connected to the lower part of the second expansion I / O port 50. The third side cover 80 matches the motherboard I / O port 70, and the lower end of the third side cover 80 is rotatably connected to the lower part of the motherboard I / O port 70. The first side cover 40 can be closed onto the first expansion I / O port 30, the second side cover 60 can be closed onto the second expansion I / O port, and the third side cover 80 can be closed onto the motherboard I / O port 70, preventing dust and water stains from entering the interior of the mid-frame 2. When using the first expansion I / O port 30, the second expansion I / O port, or the motherboard I / O port 70, the first side cover 40, the second side cover 60, or the third side cover 80 can be opened outwards. Connections can be made to expansion hardware devices in the expansion area via the first expansion I / O port 30 and the second expansion I / O port 50, and to relevant hardware on the motherboard 200 via the motherboard I / O port 70. Furthermore, because the lower end of the first side cover 40 is rotatably connected to the lower part of the first expansion I / O port 30, the lower end of the second side cover 60 is rotatably connected to the lower part of the second expansion I / O port 50, and the lower end of the third side cover 80 is rotatably connected to the lower part of the motherboard I / O port 70, the first side cover 40, the second side cover 60, or the third side cover 80 can be kept separate from the mid-frame 2 when opened, preventing loss. In addition, sealing rings can be provided on the inner edges of the first side cover 40, the second side cover 60 and the third side cover 80 to improve the sealing performance when the covers are closed.

[0029] Several bottom vents 31 are evenly distributed on the base plate 3 below the motherboard 200; the bottom of the second corner protector 7 protrudes from the lower surface of the base plate 3, and the top of the third corner protector 8 protrudes from the upper surface of the cover 4. Because the bottom of the second corner protector 7 protrudes from the lower surface of the base plate 3, a gap is formed between the base plate 3 and the work surface when the laptop is placed on a work surface, which is more conducive to the exhaust of air from the bottom vents 31, resulting in better heat dissipation.

[0030] The front side wall of the middle frame 2 is equipped with a handle 90 to improve the portability of the laptop.

[0031] The keyboard assembly 1 includes a keyboard panel 11, a touchpad 12 and a keyboard 13 mounted on the keyboard panel 11. The keyboard panel 11 is mounted on the top of the mid-frame 2 and has a hinge for connecting to the front cover 4. The keyboard 13 is a waterproof keyboard, and an elastic sealing film can be covered on the bottom of the keyboard 13 to prevent liquid from seeping into the motherboard 200. The screen assembly 5 includes a screen 51 and a screen bezel 52 that surrounds and is fixed around the screen 51.

[0032] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
