The metal shell 1 includes a bottom wall 11 and a side wall 12, and the side wall 12 is connected around the periphery of the bottom wall 11 to form a receiving space 100. The inner side of the sidewall 12 facing the accommodating space 100 is used for matching with the display screen 4. The plastic middle frame 2 is accommodated in the accommodating space 100 and connected with the metal shell 1. At least one part of the metal insert 3 is embedded on the surface of the plastic middle frame 2 close to the metal shell 1. For providing support for a plurality of corners of the electronic device housing.

Wherein, the shell 1 can be integrally formed by a metal plate through a stamping process. The plastic middle frame 2 is connected with the metal shell 1 as a plastic support and used for supporting the display screen 4 and other electronic components. The plastic middle frame 2 is generally formed by injection molding to form a frame structure suitable for being assembled with electronic components such as a battery and a mainboard.

At least one part of the metal insert 3 is embedded on the surface of the plastic middle frame 2 close to the metal shell 1, so that the metal insert 3 can be close to the metal shell 1, and the metal insert 3 provides support for a plurality of corners of the electronic equipment shell, thereby improving the overall strength and rigidity of the electronic equipment shell. When electronic equipment takes place to fall, the impact that the angle of electronic equipment casing received can transmit metal insert 3 on, avoid plastic center 2 to damage or warp under great stress, protect its inside electronic components.

It can be understood that, when the electronic device housing is assembled with the display screen 4, at least a portion of the display screen 4 is accommodated in the accommodating space 100, and the side wall 12 surrounds the periphery of the display screen 4. Optionally, the inner side surface of the sidewall 12 facing the accommodating space 100 is in clearance fit with the display screen 4, so as to prevent the metal housing 1 and the display screen 4 from being directly in hard contact and causing stress damage to the display screen 4.

According to the electronic equipment shell provided by the embodiment of the application, the plastic middle frame 2 is accommodated in the accommodating space 100 formed by the metal shell 1, and the side wall 12 of the metal shell 1 is matched with the display screen 4, so that the appearance effect of an all-metal body of the electronic equipment is realized; meanwhile, the metal insert 3 is embedded on the surface, close to the metal shell 1, of the plastic middle frame 2, and the metal insert 3 supports a plurality of corners of the electronic equipment shell, so that the overall strength and rigidity of the electronic equipment shell are improved. Compared with an all-metal shell obtained by CNC (computer numerical control) machining of a whole aluminum block, the electronic equipment shell provided by the embodiment of the application simplifies the manufacturing process and reduces the production cost under the condition that the whole aluminum block has enough strength and rigidity.

In the embodiment of the application, the metal shell 1 is an aluminum alloy plate stamping part; and/or the metal insert 3 is a magnesium aluminum alloy piece. Wherein, the aluminum alloy has the characteristics of low density and corrosion resistance. For example, the metal case 1 is integrally formed by pressing a 5-series aluminum alloy plate. Of course, other metal plate suitable for stamping may be used, such as stainless steel plate, etc., and the present application is not limited thereto. The magnesium-aluminum alloy insert can effectively enhance the rigidity of the whole electronic equipment under the condition of not greatly increasing the weight of the shell, and the reliability of the whole electronic equipment is improved. Of course, the metal insert 3 may also be formed by integrally stamping other suitable metal plates, such as stainless steel plates, aluminum alloy plates, etc., which is not limited in this application.

The second side panel 3122 may be connected to at least one of the adjacent two first side panels 3121, and may be spaced apart from the adjacent two first side panels 3121. The second side plate 3122 may be selectively added to a portion of the plastic middle frame 2 located between the two corners 2021, where the structural strength is weaker, according to the actual structure of the plastic middle frame 2, so as to improve the structural strength of the portion of the electronic device housing located between the two corners 2021.
