Detailed Description

To make the objects and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings and examples.

Fig. 3 is a schematic structural diagram of the inside of the upper housing of the mobile phone terminal in the embodiment of the present invention. As shown in fig. 3, the LCD protection module attached to the inner surface of the bottom surface of the upper casing 21 includes: an LCD protective frame 22 and a reinforcing rib 23, wherein the LCD protective frame 22 is rectangular, and the lower surface of the LCD protective frame 22 is connected with the inner surface of the bottom surface of the upper shell 21; the rib 23 has four sidewalls, and the upper surface is flush with the upper surface of the LCD bezel 22, and the lower surface is connected to the inner surface of the bottom surface of the upper case 21.

The first sidewall of the rib 23 is opposite to the second sidewall, wherein the first sidewall is connected to the outer sidewall of the LCD bezel 22, and the second sidewall is spaced apart from the inner surface of the sidewall of the upper casing 21 by a distance, i.e., is not connected to the inner surface of the sidewall of the upper casing 21. The third side wall and the fourth side wall of the reinforcing rib 23 are adjacent to the first side wall and the second side wall respectively, and the third side wall and the fourth side wall are both trapezoidal, parallel to each other and perpendicular to the upper surface and the lower surface of the reinforcing rib 23.

The third and fourth sidewalls of the reinforcing beads 23 are trapezoidal only as a specific example, and a shape such as a right triangle may be used, and when a right triangle is used, the reinforcing beads 23 do not have an upper surface. This shape is designed mainly to increase the strength and rigidity of the reinforcing ribs 23 in the case where the reinforcing ribs 23 are not connected to the inner surface of the side wall of the upper casing 21.

The utility model discloses in, the number of strengthening rib 23 is six, and the symmetric distribution is on two relative edges of LCD protecting frame 22, and wherein four distribute respectively in the extreme point position on two relative edges of LCD protecting frame 22, and two other distribute respectively in the mid point position on two relative edges of LCD protecting frame 22. Of course, the number of the ribs 23 may be other.

Fig. 4 is a schematic diagram of the LCD protection assembly according to an embodiment of the present invention, which is a cross-sectional view taken along the direction a shown in fig. 3, wherein solid arrows indicate the transmission direction of the external force. Since the ribs 23 are not connected to the inner surface of the sidewall of the upper housing 21, when the sidewall of the upper housing 21 receives an external force, the external force is transmitted to a position below the LCD along the sidewall of the upper housing 21 and is not transmitted to the LCD, thereby ensuring that the LCD is not deformed or damaged by the impact of the external force.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
