[0027] The housing structure of a mobile air conditioner, please refer to Figure 1-6, including a bottom plate 100 that forms the outer shell, two side plates 200 connecting the bottom plate 100, a front cover plate 300 connecting the front ends and top ends of the two side plates 200 respectively, a top plate 400, and a back plate 500 connecting the rear sides of the two side plates 200. The two side plates 200 are mirror-symmetrical structures. The bottom plate 100, the two side plates 200, the front cover plate 300, the top plate 400, and the back plate 500 respectively correspond to the six faces of the outer shell structure, and are combined to form a hexahedron structure as the outer shell of the mobile air conditioner. In this embodiment, each panel is made of plastic and integrally processed by an injection mold; multiple first card slots 210, second card slots 220, and third card slots 230 are respectively provided on the inner sides of the side plates 200. The first card slots 210, second card slots 220, and third card slots 230 are respectively provided on the inner sides of the side plates 200 and face the top plate 400, the front cover plate 300, and the back plate 500 respectively. Multiple first hidden card protrusions 410 matching the first card slots 210 are provided on both sides of the bottom of the top plate 400. Multiple second hidden card protrusions 310 matching the second card slots 220 are provided on both sides of the back of the front cover plate 300. Multiple third hidden card protrusions 510 matching the third card slots 230 are provided on the back plate 500; the back plate 500, the front cover plate 300, and the top plate 400 are respectively installed with the two side plates through a hidden snap structure, which facilitates the disassembly and assembly of the outer shell and hides the connection structure, making the outer shell more beautiful; multiple first screw holes 520 are provided on the back plate 500, and multiple second screw holes 250 matching the first screw holes 520 are provided on the side plates 200. In addition to the cooperation between the third card slots 230 and the third hidden card protrusions 510, the back plate 500 and the side plates 200 are fixed by screwing between the first screw holes 520 and the second screw holes 250, making the fixation between the two more stable. Two grille plates 530 are provided on the back plate 500. The grille plates 530 are connected to the back plate 500 by snaps and cover the first screw holes 520. The structure of the grille plates 530 facilitates the internal and external air flow of the mobile air conditioner. The grille plates 530 cover the first screw holes 520 at the same time, so that the first screw holes 520 and the screws are not exposed, avoiding affecting the beauty of the outer shell.

[0028] Furthermore, the back plate 500 is provided with two installation grooves 540 that match the grille plate 530. The first screw holes 520 are arranged in the installation grooves 530. A plurality of fourth hidden convex cards 531 are provided on the side of the grille plate 530 close to the back plate 500. The back plate 500 is provided with a plurality of fourth card slots 550 that match the fourth hidden convex cards 531. Two positioning convex cards 532 are provided at the bottom of the grille plate 530. The installation grooves 540 are provided with two positioning card slots 541 that match the positioning convex cards 532. When the grille plate 530 is installed, it is positioned by aligning the positioning convex cards 532 with the positioning card slots 541 and then embedding them therein. Subsequently, the whole is embedded in the installation grooves 540, and the fourth hidden convex cards 531 are embedded in the fourth card slots 550 to complete the installation. Since the first screw holes 520 are arranged in the installation grooves 530 and the grille plate 530 covers the installation grooves 540 as a whole after installation, the first screw holes 520 and the screws inside them are hidden, without affecting the appearance of the shell.

[0029] Furthermore, the first hidden convex card 410 and the second hidden convex card 310 are in an "L" - shaped structure. A plurality of front card slots 420 and rear card slots 430 are respectively provided at the front and rear ends of the top plate 400. A plurality of front convex cards 320 that cooperate with the front card slots 420 are provided on the side of the front cover plate 300 close to the top plate 400. A plurality of rear convex cards 550 that cooperate with the rear card slots 420 are provided on the side of the back plate 500 close to the top plate 400. When the shell is installed, the two side plates 200 are fixed on both sides of the bottom plate 100 by screws. Subsequently, the front cover plate 300 is aligned with the second card slots 220 of the two side plates 200 through the second hidden convex card 310 in an "L" - shaped structure and embedded. After embedding, the front cover plate 300 is slid to complete the connection with the two side plates 200. Similarly, the top plate 400 is installed on the tops of the two side plates 200 in the same sliding buckle manner. While the top plate 400 is sliding, the front convex cards 320 on the front cover plate 300 are embedded in the front card slots 420 of the top plate 400, and the top plate 400 and the front cover plate 300 are connected. At this time, the basic connection of the top plate 400, the front cover plate 300, and the two side plates 200 is completed.

[0030] Further, a plurality of third screw holes 110 are respectively provided on the front and rear sides of the bottom plate 100. First connecting plates 250 that match the third screw holes 110 are respectively provided on both sides of the side plates 200. Screw holes and bump points for positioning are provided on the first connecting plates 250, and concave points for positioning are provided outside the third screw holes 110. When the side plates 200 are connected to the bottom plate 100, after the side plates 200 are positioned through the positioning bump points and concave points, screws are screwed into the third screw holes 110 to achieve fixed connection; fourth screw holes 330 are provided on the inner side of the front cover plate 300. Second connecting plates 260 that match the fourth screw holes 330 are provided on the side plates 200. Screw holes are provided on the second connecting plates 260. After the front cover plate 300 and the side plates 200 are connected by hidden snap fasteners, screws are locked in the fourth screw holes 330 and the second connecting plates 260 to ensure the stable connection between the front cover plate 300 and the side plates 200. Since the fourth screw holes 330 and the second connecting plates 260 are respectively located inside the front cover plate 300 and the side plates 200, screws can be extended from the back to the inside to be screwed before the installation of the back plate 500. This structure not only ensures the stability of the connection but also does not expose the screws after installation, which affects the aesthetics; a third connecting plate 440 extending downward is provided on the rear side of the top plate 400. Fifth screw holes 270 that match the third connecting plate 440 are provided on the side plates 200. After the installation of the bottom plate 100, the two side plates 200, the front cover plate 300, and the top plate 400 is completed, the back plate 500 is installed as the last side of the housing. The back plate 500 is mounted on the two side plates 200 through the cooperation of the third hidden snap protrusions 510 and the third card slots 230. When the back plate 500 is closed, the rear snap protrusions 550 on the back plate 500 are embedded into the rear card slots 420 on the top plate 400 to achieve the connection between the back plate 500 and the top plate 400. After the back plate 500 completes the snap connection with the top plate 400 and the side plates 200, screws are locked in the third connecting plate 400 and the fourth screw holes 270 on the top plate to reinforce the connection. Screws are used to reinforce the connection between the back plate 500 and the side plates 200 through the first screw holes 520 and the second screw holes 240. Finally, the grille plate 530 is installed to complete the installation of the housing.
