Shell component and mobile terminal

Abstract

Embodiments of the invention disclose a shell component and a mobile terminal. The shell component comprises a first shell and a second shell fixed on the first shell, wherein the first shell is provided with a positioning hole; the second shell is provided with a positioning block matched with the positioning hole; a deformation bulge is arranged at the peripheral side of the positioning block; the deformation bulge generates deformation under the extrusion of the inner sidewall of the positioning hole and abuts against the inner sidewall of the positioning hole tightly in order to be matched with a tolerance clearance between the positioning block and the positioning hole. According to the shell component and the mobile terminal, the deformation bulge is arranged at the peripheral side of the positioning block and abuts against the inner sidewall of the positioning hole tightly and generates deformation under the extrusion of the inner sidewall of the positioning hole in order to be matched with the tolerance clearance between the positioning block and the positioning hole, so that a reasonable fit clearance between a first cover plate and a second cover plate is guaranteed, and thus the appearance performance of the shell component is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a housing assembly and a mobile terminal. Background technique [0002] In the current assembly scheme of mobile terminal housing components, there is usually a three-stage structure, including a second housing and two first housings that fit side by side on both sides of the second housing, and the second housing is fixed by dispensing In the middle frame, the first housing is fixed through the positioning block and the positioning hole of the middle frame, and is fastened by double-sided adhesive tape. However, under normal circumstances, due to the manufacturing tolerances of the first shell and the second shell, and the positioning tolerance of the dispensing process of the second shell, the manufacturing tolerance and the positioning tolerance are accumulated. Therefore, unreasonable situations such as excessive fit gap or interference fit between the first shell and the...

However, under normal circumstances, due to the manufacturing tolerance of the first shell and the second shell, and the positioning tolerance of the dispensing process of the second shell, the cumulative manufacturing tolerance and positioning tolerance

Therefore, unreasonable situations such as excessive fit gap or interference fit between the first shell and the second shell tend to occur between the first shell and the second shell, which affects the appearance of the shell assembly, and even Bulging of shell components occurs
