[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To make the description of this disclosure more detailed and complete, illustrative descriptions of the embodiments and specific examples of this utility model are provided below; however, this is not the only form of implementing or using the specific examples of this utility model. The embodiments cover the features of multiple specific embodiments and the methods, steps, and sequences for constructing and operating these specific embodiments. However, other specific embodiments may also be used to achieve the same or equivalent functions and sequence of steps.

[0019] Please refer to Figures 1 to 5The frameless phone case provided in this embodiment includes a frame 1 and a back cover 2. The frame 1 is made of metal, which has a good texture. When the user holds the phone case with one hand, they usually mainly contact the frame 1, thus obtaining a good contact experience. The back cover 2 is made of plastic, which has a certain degree of elasticity.

[0020] The frame 1 and the back cover 2 are detachable. The back cover 2 has multiple sets of toothed grilles 21A formed by several vertical fixing strips 21 along its perimeter. In this embodiment, two sets of toothed grilles 21A are symmetrically arranged along the two long edges of the back cover 2, with a gap between the two sets on each edge. Two sets of toothed grilles 21A are also spaced apart along the edge of the short edge of the back cover 2 that is on the same side as the bottom of the phone. It should be noted that the position and number of toothed grilles along the perimeter of the back cover can be adjusted as needed, and this invention does not limit this.

[0021] A recessed slot 11 is provided on the inner wall of the frame 1, the number and position of which correspond to the position and number of the toothed grilles 21A. A ring edge 22 is also provided on the periphery of the back cover 2, between the toothed grilles 21A. The size of the receiving cavity formed by the toothed grilles 21A and the ring edge 22 of the back cover 2 is slightly larger than the size of the mobile phone. When the mobile phone is placed in this receiving cavity and fits against the back cover, there is a gap between its outer periphery and the toothed grilles 21A. The fixing strip 21 cooperates with the recessed slot 11 to connect the back cover 2 to the frame 1. When the fixing strip 21 is squeezed by the force from the frame 1, it tilts towards the gap between the mobile phone and the toothed grilles 2, and then returns to its original shape under the elasticity of the plastic, thereby connecting and fixing with the recessed slot 11.

[0022] The snap-on metal frame shell provided in this embodiment of the utility model allows for easy installation and removal of the back cover and metal frame through the cooperation of the elastic fixing strip on the plastic back cover and the concave slot on the metal frame, improving the convenience of user operation and providing a good user experience.

[0023] Please refer to the following: Figure 5The upper end of the fixing strip 21 is provided with a first protrusion 211 extending outward from the back cover 2. The end face of the first protrusion 211 facing the concave slot 11 has an upper inclined surface 211a and a lower inclined surface 211b. The concave slot 11 extends downward from the end facing the back cover 2 to form a second protrusion 111, and the surface of the second protrusion 111 is inclined. According to the number of fixing strips 21 in a set of toothed rails 21A that need to be matched, each concave slot 11 is provided with the same number of second protrusions 111. When the fixing strip 21 is fixed to the concave slot 11, when the fixing strip 21 is squeezed by the force from the frame 1, it tilts towards the gap S between the mobile phone P and the toothed rail 2, and then returns to its original shape under the elastic action of the plastic, so that the first protrusion 211 on the fixing strip 21 is placed in the concave slot 11, and the lower inclined surface 211b of the first protrusion fits against the inclined surface of the second protrusion 111.

[0024] The snap-on metal frame shell provided in this embodiment of the utility model has an upper and lower inclined surface on the end face of the first protrusion on the fixing strip. This not only makes it easier for the first protrusion to enter the concave slot, but also makes the connection between the fixing strip and the concave slot more stable by the lower inclined surface of the first protrusion cooperating with the inclined surface of the second protrusion.

[0025] Secure the frame 1 and the back cover 2 to wrap the side of the phone except for the screen. There is also a protective cotton 3 between the frame 1 and the outer perimeter of the wrapped phone to prevent the frame 1 from scratching the surface of the phone.

[0026] The edge of the frame 1 near the back cover 2 has at least one disassembly notch 12. In this embodiment of the invention, each of the two long edges of the frame 1 has a disassembly notch 12 located near the bottom of the phone. The disassembly notch 12 facilitates the separation of the frame 1 and the back cover 2.

[0027] The edge 1, facing away from the back cover 2, extends vertically inward to form an edge 13, which is used to hold the phone placed inside the back cover 2 in place, preventing the phone from falling off the edge 1 away from the back cover 2. In optional embodiments, a tempered glass film, privacy film, or other film may also be provided on the edge 13.

[0028] It is understood that the mobile phone protective case provided by this utility model has corresponding slots on the frame and back cover for the camera, volume buttons, power button, speaker holes, etc., according to the shape of the mobile phone to which it is adapted. As a conventional design, it will not be described in detail here.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
