At present, the mainstream smart phones have a high-definition photographing function, part of high-end smart phones also have a wireless charging function, most of backshells of the smart phones are mainly made of plastic or glass, after the backshells are molded, camera openings on the backshells of the smart phones are generally directly formed, and then a camera metal component is added to be assembled with a backshell hole, so that the camera is higher than a backshell base plane, therefore, the camera lens is not easy to scratch in use, the photographing effect is prevented from being influenced, and the manufacturing is more complex; some mobile phones with wireless charging function transmit signals through electromagnetic waves, and the metal components can shield the electromagnetic waves, so that the wireless charging efficiency is greatly reduced.

The utility model has the following contents:

the utility model aims at prior art not enough, and provide a take cell-phone backshell of camera protection, its structural design science, the cell-phone backshell adopts composite sheet PC + PMMA, PC, PMMA, ABS, PET, glass fiber board, arbitrary combination between glass and the above-mentioned material, through high-pressure shaping, and establish a boss to camera trompil department and avoid the lens of cell-phone camera to be difficult for being scraped the flower by wearing and tearing, thereafter, shell machining precision is high, the trompil location is accurate, the outward appearance is graceful, use and feel, and do not influence wireless charging effect, in industry receive good comment.

In order to achieve the above object, the utility model discloses a following technical scheme, a take cell-phone backshell of camera protection, including the back lid, be equipped with finger print hole and camera hole on the back lid, back lid back be the quadrangle geometry form, the four corners of back lid is the arc angle, the both sides limit of back lid is equipped with the circular arc limit of bending, the edge in camera hole is equipped with the boss.

The rear cover body is made of one of composite boards PC + PMMA, PC, PMMA, ABS, PET, glass fiber boards, glass and any combination of the materials.

The fingerprint hole is in one of a circle, an ellipse, a square, a rectangle, a diamond, a trapezoid, a polygon and any combination of the figures.

The shape of the camera hole is one of a circle, an ellipse, a square, a rectangle, a rhombus, a trapezoid, a polygon and any combination of the figures.

The protruding height of boss be 0 to 5mm, the edge of boss is any one of straight line and pitch arc to the connecting wire of back lid, the edge of boss is 0 to 90 degrees to the contained angle of back lid.

The utility model discloses beneficial effect does: the utility model provides a take cell-phone backshell of camera protection, includes the back lid, is equipped with finger print hole and camera hole on the back lid, back lid back be the quadrangle geometry form, the four corners of back lid is the arc angle, the both sides limit of back lid is equipped with the circular arc limit of bending, the edge in camera hole is equipped with the boss, the cell-phone backshell adopts composite sheet PC + PMMA, PC, PMMA, ABS, PET, glass fiber board, glass and the above-mentioned material between the arbitrary combination, through high-pressure molding, and establish a boss to camera trompil department and avoid the lens of cell-phone camera to be difficult for being scraped the flower by wearing and tearing, thereafter the shell machining precision is high, the trompil location is accurate, the outward appearance is graceful, uses and feels, and does not influence wireless charging effect, receives good comment in.
