Description

Technical Field

[0001] The present invention relates to the technical field of mobile phones, and in particular to a mobile phone front shell and a mobile phone. Background Art

[0002] With the improvement of technology, the appearance of mobile phones is becoming thinner and more fashionable. As an important component of mobile phones, the mobile phone case has higher and higher requirements for beauty and strength. At present, the front shell assembly of mobile phones generally includes hardware connectors and in-mold injection molded plastic shells. After injection molding, the hardware connectors and the plastic shell are combined into an integrated structure.

[0003] For example, a Chinese patent with application number CN201821099904.4 discloses a mobile phone front shell assembly, including a plastic shell and a hardware connecting piece. The hardware connecting piece is combined with the plastic shell in an injection mold to form an integrated structure. The hardware connecting piece is an aluminum sheet with notches cut at the corners of the aluminum sheet. The periphery of the aluminum sheet is bent upward, and glue holes are provided at the bends of the aluminum sheet.

[0004] During the injection molding of the plastic shell of the mobile phone front shell assembly, the plastic flows into the glue hole, so that the aluminum sheet is engaged with the plastic shell through the glue hole to improve the structural strength of the aluminum sheet and the plastic shell. However, due to the small aperture of the glue hole, the engagement area between the plastic shell and the aluminum sheet through the glue hole is small, so there is still a problem of low structural strength between the aluminum sheet and the plastic shell. On the other hand, although the aluminum sheet has good heat dissipation performance, the hardness of the aluminum sheet is low, and it is easy to be damaged when the aluminum sheet and other mobile phone accessories are locked by screws.

[0005] Therefore, there is an urgent need for a mobile phone front shell with high structural strength and good heat dissipation performance. Utility Model Content

At this time, the plastic shell forms a limiting groove at the limiting boss to make the plastic shell and the aluminum-titanium composite strip tightly bite, that is, the bite area between the plastic shell and the aluminum-titanium composite metal part is increased by the injection groove and the limiting groove, thereby improving the strength of the overall structure. On the other hand, since the metal part is made of aluminum-titanium composite material, while retaining the heat dissipation performance of the aluminum sheet, the hardness of the metal part is also improved, further improving the strength of the overall structure.

[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0033] like Figures 1 to 4As shown, a front shell 10 of a mobile phone in an embodiment includes an aluminum-titanium composite metal part 100 and a plastic shell 200, wherein the plastic shell 200 is coated on the outer periphery of the aluminum-titanium composite metal part 100, and the aluminum-titanium composite metal part 100 includes an aluminum-titanium composite sheet 110 and an aluminum-titanium composite strip 120, wherein the aluminum-titanium composite strip 120 is connected to the outer periphery of the aluminum-titanium composite sheet 110, and the aluminum-titanium composite strip 120 and the aluminum-titanium composite sheet 110 jointly form an injection molding groove 100a, and a part of the structure of the plastic shell 200 is formed in the injection molding groove 100a, and the aluminum-titanium composite strip 120 is convexly provided with a limiting boss 121, and the plastic shell 200 is provided with a limiting groove 210, and the limiting boss 121 is located in the limiting groove 210.
