Referring to fig. 1 to 5, the housing 10 according to an embodiment of the present invention includes a middle plate 100, a frame 200 and a plastic part 300, wherein the frame 200 includes an aluminum alloy frame, a stainless steel frame or a titanium alloy frame, i.e., the frame 200 may be made of an aluminum alloy, a stainless steel or a titanium alloy material. Of course, the middle plate 100 and the frame 200 may be made of the same material, i.e., the middle plate 100 may also be made of aluminum alloy, stainless steel or titanium alloy.

In some embodiments, the middle plate 100 and the bezel 200 may be integrally formed, for example, by CNC machining, or by die casting. In other embodiments, the middle plate 100 and the bezel 200 may be connected by die-casting and CNC-forming the bezel 200 and then welding or riveting the middle plate 100 and the bezel 200, while ensuring the structural strength and the appearance quality.

In some embodiments, the rim 200 is connected to the periphery of the middle plate 100, that is, the rim 200 is disposed around the middle plate 100, the rim 200 and the middle plate 100 enclose an open cavity 110, the surface of the middle plate 100 forms the bottom wall of the open cavity 110, and the inner side 220 of the rim 200 forms the sidewall of the open cavity 110. Specifically, the middle plate 100 has an outer surface 210 and an inner side surface 220, the outer surface 210 is disposed horizontally, the inner side surface 220 is disposed vertically, and the outer surface 210 and the inner side surface 220 may be connected at an included angle of ninety degrees. The inner side 220 of the rim 200 defines part of the boundary of the open cavity 110, i.e., the inner side 220 of the rim 200 is a sidewall of the open cavity 110. A portion of the inner side 220 of the bezel 200 is recessed to form an anti-space groove 221, and the anti-space groove 221 extends to the outer surface 210 of the bezel 200. The middle plate 100 has a to-be-processed portion 120 disposed on a surface thereof, and the to-be-processed portion 120 is disposed in the open cavity 110 and adjacent to the avoiding groove 221.

The plastic member 300 includes a first mounting portion 310 and a second mounting portion 320, the first mounting portion 310 and the second mounting portion 320 are connected to each other, the first mounting portion 310 is connected to the outer surface 210 of the bezel 200, and the second mounting portion 320 is entirely located in the avoiding groove 221. When the CNC probe extends into the open cavity 110 to process the station 120, the second mounting part 320 keeps a set distance from the CNC probe. Because the second mounting part 320 and the CNC probe keep a set distance, the second mounting part 320 does not interfere with the CNC probe extending into the open cavity 110, the CNC probe is ensured to smoothly enter the open cavity 110 to process the processing position 120, and finally, the convenience of processing the shell 10 is ensured.

The plastic part 300 is connected with the frame 200 in an injection molding way, in the injection molding connection process, the middle plate 100 and the frame 200 which are connected together are firstly placed into a cavity of an injection mold, then molten plastic liquid is injected into the cavity of the injection mold through an injection machine, and the plastic liquid is gradually cooled after the pressure maintaining set time. And finally, after the molten plastic liquid is solidified into the plastic part 300, taking the frame 200 and the middle plate 100 connected with the plastic part 300 out of the cavity of the injection mold.

For the conventional design scheme of the housing 10, since the inner side surface 220 of the frame 200 is not provided with the avoiding groove 221, during the injection molding process, there is an overflow phenomenon, that is, the plastic liquid on the outer surface 210 of the frame 200 overflows and attaches to the inner side surface 220 of the frame 200, during the curing and molding process, the plastic liquid attached to the inner side surface 220 of the frame 200 is cured to form a flange, and the flange protrudes out of the inner side surface 220 of the frame 200 by a set height. Because the to-be-processed position 120 of the middle plate 100 is disposed close to the inner side surface 220 of the frame 200, when the CNC probe extends into the open cavity 110 to be processed at the to-be-processed position 120, the flanging on the inner side surface 220 of the frame 200 interferes with the CNC probe, i.e., the flanging prevents the CNC probe from entering the open cavity 110 to be processed at the to-be-processed position 120.

In the above embodiment, by designing the avoiding groove 221, when the molten plastic solution overflows from the outer surface of the frame 200, the overflowing plastic solution flows into the avoiding groove 221, and because the avoiding groove 221 has sufficient capacity, after the plastic solution in the avoiding groove 221 is solidified to form the second mounting part 320, the second mounting part 320 is completely located in the avoiding groove 221, that is, the second mounting part 320 does not protrude a certain height from the inner side surface 220, for example, the surface of the second mounting part 320 keeps a set distance from the inner side surface 220, which can be simply understood as that the surface of the second mounting part 320 is lower than the set height (the height perpendicular to the direction of the inner side surface 220) of the frame 200; for another example, the surface of second mounting portion 320 is flush with inner surface 220, and it can be simply understood that the surface of second mounting portion 320 is as high as inner surface 220 of bezel 200 (height perpendicular to inner surface 220).

When the CNC probe extends into the open cavity 110 to machine the processing position 120, the second mounting portion 320 does not interfere with the CNC probe extending into the open cavity 110, so as to ensure that the CNC probe smoothly enters the open cavity 110 to machine the processing position 120. Meanwhile, through the cooperation of the second mounting part 320 and the avoiding groove 221, a strong engagement relationship is formed between the whole plastic part 300 and the frame 200, the connection strength between the whole plastic part 300 and the frame 200 is improved, and the plastic part 300 is prevented from being peeled off from the frame 200 and cracked.

In some embodiments, the plastic member 300 further includes a third mounting portion 330, the third mounting portion 330 is connected to the first mounting portion 310, and the third mounting portion 330 is attached to the inner side 220 and protrudes a predetermined length from the inner side 220. Since the third mounting part 330 is connected to the inner side 220 of the bezel 200, the connection strength between the entire plastic member 300 and the bezel 200 is further increased. In other embodiments, a sunken groove may be further formed on the inner side surface 220 of the frame 200, the sunken groove is formed in a shape similar to that of the clearance groove 221, in the injection molding process, the molding compound in the sunken groove forms a part of the third mounting part 330, and meanwhile, the volume of the third mounting part 330 is greater than the volume of the sunken groove, so that a part of the third mounting part 330 protrudes out of the sunken groove, the part of the third mounting part 330 outside the protruding sunken groove also protrudes out of the inner side surface 220 of the frame 200 for a set height, and because the part 120 of the middle plate 100 to be processed is close to the third mounting part 330, the interference of the CNC probe caused by the protrusion of the third mounting part 330 out of the inner side surface 220 of the frame 200 for the set height can be disregard.

In some embodiments, the first mounting portion 310 gradually increases in cross-sectional dimension in a direction from the outer surface 210 toward the middle plate 100, i.e., from top to bottom. For example, the cross-section of the first mounting portion 310 may be an isosceles trapezoid or the like. This ensures a sufficient contact area between first mounting portion 310 and outer surface 210 of bezel 200 to ensure the connection strength between first mounting portion 310 and bezel 200.

The utility model also provides an electronic equipment, electronic equipment include foretell casing 10, and electronic equipment can be cell-phone or panel computer.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
