[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5The utility model provides a technical solution: a mobile phone middle frame, including a frame body 1, the inner end edge of the frame body 1 protrudes inward, and the four corners of the frame body 1 are connected to the inner side of the support frame 2, and the support rods 4 are fixedly connected between the support frames 2 at the four corners. The support rods 4 are fixedly connected to the inner side wall of the frame body 1, and the support rods 4 are distributed up and down inside the frame body 1. The mounting holes on the frame body 1 are all located between the two support rods 4. The two support rods 4 are fixedly connected to the reinforcing ribs 5 at one end near the edge of the frame 1. The reinforcing ribs 5 are triangular in shape and fixedly connected to the inner side wall of the frame body 1. The two support rods 4 and several reinforcing ribs 5 form a torsion-resistant support; the frame body 1 of the middle frame is located in the middle position of the mobile phone, with the screen at the front end, the internal electronic components and the back cover in the middle and rear ends. By fixing the support frames 2 at the four corners of the frame 1, the support rods The support frame 2 can increase the rigidity of the four corners of the frame 1, and can play the role of internal support when encountering a collision to avoid the four corners from sinking. At the same time, the support frames 2 at the four corners are connected by two upper and lower support rods 4 to form a frame structure with the same shape as the frame 1 inside. The upper and lower support rods 4 are fixedly connected to the inner side wall of the frame 1, which can support the weak side of the frame 1 and prevent the frame 1 from being twisted by the support rods 4, and avoid the horizontal and vertical torsional deformation of the frame 1. Several reinforcing ribs 5 are fixedly connected to the end face of the support rod 4 near the edge of the frame 1. Several reinforcing ribs 5 with equal spacing can prevent large-area deformation of the side of the frame 1, and then the reinforcing ribs 5 can reduce the support force area of the side of the frame 1, which can correspondingly improve the impact resistance and support of the outside of the frame 1.

[0022] like Figure 3 As shown, a fixing block 6 is fixedly connected in the middle of the two support rods 4, and the upper and lower ends on both sides of the fixing block 6 are triangular. The thickness of the fixing block 6 is equal to that of the support rod 4, and the outer end of the fixing block 6 is fixedly connected to the frame 1. The fixing block 6 is located in the middle of the two support rods 4 and is fixedly connected. When the two support rods 4 are subjected to side impact, they can play a supporting role through the fixing block 6, and then the fixing block 6 can improve the connection stability between the support rods 4, thereby making the overall structure more stable.

[0023] like Figure 5 As shown, the upper and lower protruding ends of the inner edge of the frame 1 are fixedly connected with a sealing sheet 7, and the inner end of the sealing sheet 7 protrudes from the inner end of the edge of the frame 1. The sealing sheet 7 plays a role of offset sealing for the screen and the back cover, further improving the connection sealing between the back cover and the screen and the frame 1, and reducing the possibility of external dust entering the interior.

[0024] like Figure 5As shown, a volume groove 8 is provided on the inner edge of the frame 1 at the upper end of the sealing sheet 7, and the cross-section of the volume groove 8 is rectangular. The back cover and the screen are doubly connected to the frame 1 by snapping and bonding, and the volume groove 8 can increase the bonding area with the adhesive, thereby improving the installation stability of the back cover and the screen. The cross-section of the volume groove 8 is rectangular, which can maximize the bonding area.

[0025] like Figure 4 As shown, the support frame 2 is in a U-shaped configuration, and a buffer pad 3 is fixedly connected to the inside of the support frame 2, and the buffer pad 3 is a rubber block; the U-shaped support frame 2 can provide stable support up and down, thereby making the upper and lower ends of the four corners of the frame 1 more firm. At the same time, the buffer pad 3 is fixed inside the support frame 2, and the buffer pad 3 can slow down the force transmitted inward when the four corners of the frame 1 are bumped, thereby reducing the impact on the internal electronic components.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the support frame 2, support rod 4, reinforcement rib 5 and fixing block 6 are all integrally formed with the frame 1. The support frame 2, support rod 4, reinforcement rib 5 and fixing block 6 are all supported by the same material as the frame 1. The frame 1 is integrally formed regardless of whether it is made of plastic or metal, which can provide more stable support and connection stability.
