2. the second clearance is reduced or increased, and/or the

positioning projections

41a,41b are elastically deformed in the thickness direction of the cellular phone at the contact positions with the

positioning clearances

42a,42 b.

Thereby avoiding air bubbles generated between the panel 22 and the mobile phone when the panel 22 is attached, and reducing the difficulty of the user in realizing the attachment without air bubbles.

Further, the inner side surface of the panel 22 is adhered and fixed with the mobile phone screen;

an upper inclined surface 223 is arranged at the joint of the bottom surface of the frame 21 of the upper cover 2 and the outer peripheral surface, and a lower inclined surface 113 is arranged at the joint of the top surface of the frame 11 of the bottom shell 1 and the inner peripheral surface; the upper inclined surface 223 is disposed opposite to and in parallel with the lower inclined surface 113, and the upper inclined surface 223 and the lower inclined surface 113 are formed with a third clearance in the thickness direction of the mobile phone and/or the upper inclined surface 223 and the lower inclined surface 113 are elastically contacted in the thickness direction of the mobile phone.

In the present embodiment, when the upper inclined surface 223 and the lower inclined surface 113 are in contact with each other, for example, one end of the upper cover 2 is inclined, and the edge of the upper inclined surface 223 temporarily contacts with the lower inclined surface 113, the guiding or auxiliary positioning function can be performed.

Similarly, when the thickness of the handset varies relative to the nominal dimension, non-predetermined deformation of the panel 22 can be prevented by:

2. the second clearance is reduced or increased, and/or the

positioning projections

positioning clearances

42a,42 b; the method comprises the steps of,

3. the third clearance is reduced or increased, and/or the upper inclined surface 223 and the lower inclined surface 113 are elastically deformed at the contact position in the thickness direction of the mobile phone.

Further, in the thickness direction of the mobile phone, the thickness between the bottom surface S1 and the top surface S3 of the frame 21 of the upper cover 2 is 1.5 to 3 times the thickness of the panel 22, and the height of the bottom surface of the frame 21 of the upper cover 2 is close to the height of the inner side surface of the panel 22; the rim 11 of the bottom case 1 includes a side wall opposite to the side of the mobile phone, the height of which is close to or equal to the thickness of the mobile phone.

In this embodiment, since the thickness of the panel 22 is generally smaller, the thickness of the frame 21 of the upper cover 2 is reduced, so that the upper cover 2 as a whole tends to be more plate-shaped, and the upper cover 2 is easier to bend, i.e. the panel 22 is prevented from being removed from the frame, the edge of the panel 22 is protected, and the attaching operation of the panel 22 is easy to be performed. In addition, the

positioning projections

41a,41b are provided on the frame 21 of the upper cover 2, which is more advantageous in ensuring the strength of the frame 21 of the upper cover 2 while ensuring the positioning fit length than the groove-like cavity structure is provided on the frame 21 of the upper cover 2.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
