[0018] The utility model will be further described in detail in combination with the drawings and specific implementation.

[0019] In this embodiment, refer to Figures 1-5 The specific implementation of a plastic mobile phone shell of shock absorption and anti-falling, including top cover 1 and back plate 2, the top cover 1 is provided with frame 3 around, the back plate 2 is provided with buckle 4 for cooperating with the buckle slot 5 on the frame 3, the buckle 4 is provided with guiding part 12, the effect of guiding part 12 is that frame 3 exerts pressure on guiding part 12 when installing back plate 2, so that buckle 4 deforms inward. When buckle 4 moves to the position of buckle slot 5, buckle 4 resets and buckles into buckle slot 5, thereby fixing back plate 2. The fixing mode of buckle 4 simplifies the process of assembly, does not need additional screw fixing, reduces the number of parts, thereby reducing production cost.

[0020] In addition, the frame 3 inside is provided with limiting slot 10 around, the back plate 2 is embedded and installed in the limiting slot 10, so that the frame 3 surrounds the outer edge of the back plate 2. To ensure that back plate 2 cannot be easily knocked, thereby providing protection for back plate 2. Further, waterproof pad 11 is arranged between limiting slot 10 and back plate 2, the waterproof pad 11 preferably adopts silica gel material, silica gel has good sealing performance and high and low temperature resistance characteristics, and can adapt to various environmental conditions. In addition, the silica gel material also has certain anti-aging performance, can prolong the service life of waterproof pad 11, and ensures long-term effective protection.

[0021] Further, when the back plate 2 cooperates with the limiting groove 10, the waterproof pad 11 is compressed to deform, effectively closing the gap between the limiting groove 10 and the back plate 2, which not only prevents liquid or dust from penetrating into the interior and damaging the electronic components, but also absorbs and buffers part of the external impact force due to the elastic characteristics of the waterproof pad 11, thereby further enhancing the protection of the internal structure of the mobile phone.

[0022] Further, the middle of the top cover 1 is provided with a keel 6 abutting against the back plate 2, thereby enhancing the supporting force and stability between the top cover 1 and the back plate 2 and significantly improving the strength of the overall structure. This makes the top cover 1 and the back plate 2 have superior impact resistance when subjected to impact. In addition, the two ends of the keel 6 are provided with V-shaped structures connected with the frame 3. The overall rigidity of the frame 3 is enhanced, so that it has better supporting force when subjected to side impact. The V-shaped structure includes two symmetrically arranged supporting arms 7. The supporting arm 7 is designed in a circular arc shape, which can effectively disperse the impact force uniformly, avoid stress concentration phenomenon, reduce the impact force directly transmitted to the interior of the mobile phone, and further improve the anti-falling performance of the mobile phone. In practical application, this design can effectively prolong the service life of the mobile phone and improve the user experience.

[0023] Further, the keel 6 is provided with a threading hole 9, which allows the internal lines of the mobile phone to pass through the keel 6. This not only makes the internal wiring of the mobile phone more neat and orderly. In addition, the threading hole 9 can also reduce the bending degree of the lines in the mobile phone, reduce the damage risk caused by excessive bending, and thereby enhance the reliability and durability of the product.

[0024] In addition, the bottom of the frame 3 is equipped with a dismounting groove 8, which facilitates the user to easily pry open the back plate 2 of the mobile phone for dismounting by using a fingernail or a special tool. Such a design significantly simplifies the mobile phone maintenance process, making it more convenient and efficient.

[0025] Further, the edges of the top cover 1, the keel 6, the supporting arm 7, the frame 3 and the back plate 2 are all designed with rounded corners. This design not only improves the comfort when holding the mobile phone, but also helps the manufacturer to quickly demold during the injection molding production process, while reducing the risk of product damage.

[0026] The beneficial effects of the utility model are as follows: by arranging the keel 6 in the middle of the top cover 1 and connecting it with the frame 3 on both sides, it is ensured that the frame 3 can obtain sufficient supporting force when subjected to side impact, and in addition, the V-shaped structure at both ends of the keel 6 helps to disperse the impact force and reduce stress concentration phenomenon, thereby further enhancing the structural stability of the mobile phone as a whole and effectively preventing damage to the internal electronic components of the mobile phone.
