Description

Connection structure between mainboard upper cover and mainboard lower cover and mobile terminal

technical field

The utility model relates to the field of electronic equipment, in particular to a connection structure between a mainboard upper cover and a mainboard lower cover and a mobile terminal.

Background technique

With the thinning development of mobile terminals (such as smart phones, tablet computers, etc.), users are paying more and more attention to the stiffness performance of mobile terminals. In the prior art, a mobile terminal generally includes a mainboard upper cover and a mainboard lower cover. An accommodating cavity is provided between the mainboard upper cover and the mainboard lower cover. The accommodating cavity is generally used for accommodating electronic components such as a mobile terminal mainboard. However, due to the lack of structural components that can effectively resist deformation between the upper cover of the main board and the lower cover of the main board, the overall rigidity of the mobile terminal is low. Specifically, the middle region between both end portions of the mobile terminal has the lowest rigidity. When the mobile terminal is subjected to external force (such as falling, impact, etc.), it is prone to bending deformation and twisting deformation, resulting in poor reliability of the product and reducing user experience. Even if a metal insert is added to the main board cover (that is, the main board cover includes a metal insert and a plastic shell injection-molded on the metal insert), the overall rigidity of the mobile terminal is improved. However, by replacing the material of the main force-bearing parts to improve the overall rigidity of the mobile terminal, the effect is difficult to meet expectations, and the improvement of the overall rigidity of the mobile terminal is not obvious.
