Curved surface cover plate, processing method of curved surface cover plate and terminal

Abstract

The invention discloses a curved surface cover plate, a processing method of the curved surface cover plate and a terminal, and relates to the technical field of terminals. The problems of how to improve the hand feeling and the appearance effect of the curved surface cover plate, reduce the machining difficulty of the curved surface cover plate and improve the attaching yield of the curved surface cover plate and a display screen are solved. The curved surface cover plate comprises a front surface and a back surface, wherein the front surface comprises a first middle region, two first edge regions and two second edge regions; wherein the first edge area and the second edge area are both cambered surfaces, the back surface comprises a second middle area and two third edge areas, the two third edge areas are respectively opposite and parallel to the two first edge areas, the second middle area is parallel to the first middle area, and the second middle area is opposite to the first middle area and the two second edge areas. The curved surface cover plate is used in the terminal to cover a screen or a battery.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a curved cover plate, a processing method of the curved cover plate and a terminal. Background technique [0002] At present, in order to improve the appearance of terminals such as mobile phones and pads, the screen cover or battery cover of the terminal is gradually developing from a flat surface to a curved surface. [0003] Existing curved covers include single-curved 3D covers and hyperbolic 3D covers. Single-curved 3D covers mean that only two opposite sides of the cover form a curved shape that curves toward the back of the cover. Hyperbolic 3D covers are It means that the four sides of the cover form a curved shape that bends toward the back side of the cover. Compared with the single-curved 3D cover, the hyperbolic 3D cover has a better feel and appearance, but the hyperbolic 3D cover is curved on the four sides. In the process, material extrusion is easy to...

Problems solved by technology

[0003] Existing curved covers include single-curved 3D covers and hyperbolic 3D covers. Single-curved 3D covers mean that only two opposite sides of the cover form a curved shape that curves toward the back of the cover. Hyperbolic 3D covers are It means that the four sides of the cover form a curved shape that bends toward the back side of the cover. Compared with the single-curved 3D cover, the hyperbolic 3D cover has a better feel and appearance, but the hyperbolic 3D cover is curved on the four sides. In the process, material extrusion is easy to occur at the junction between two adjacent sides, and it is difficult to form a smooth transition surface. Therefore, the processing is difficult and the molding yield is low. Moreover, the four sides of the back of the hyperbolic 3D cover are arc edges. When used as a screen cover, in the process of pasting the display on the back, the flatness of the pasting of the display at the junction between two adjacent arc edges on the back is low, and air bubbles are likely to occur, so the display and The bonding yield of the cover plate is low
