In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0030] See also Figures 1 to 5 The utility model proposes a locking structure for the snap connection between the first frame body 1 and the second frame body 2, characterized in that the locking structure includes a slide groove 11, a magnetic attraction slider 3 and a snap-on portion 21; the slide groove 11 is arranged on the first frame body 1 for the magnetic attraction slider 3 to be slidably connected; a cantilever 31 is extended on the magnetic attraction slider 3 in a direction close to the second frame body 2, and a flexible hook portion 32 is protruded along the vertical direction; the snap-on portion 21 is arranged on the second frame body 2 for cooperating with the flexible hook portion 32 for snapping, and an avoidance groove 22 is formed between the snap-on portion 21 and the second frame body 2, and the avoidance groove 22 is used for the flexible hook portion 32 to be slidably connected; in this embodiment, the first frame body 1 and the second frame body 2 are respectively provided with a first magnet 12 and a second magnet 23, and the magnetic attraction slider 3 is provided with a third magnet 33, and the first magnet 12 and the second magnet 23 are used to make the third magnet 33 move toward the direction close to the snap-on portion 21.

[0031] Specifically, the first frame 1 and the second frame 2 are square structures with an opening on one side, which are used to place the mobile device to be protected (such as a mobile phone, a Bluetooth keychain, etc.) from the opening. The side thereof has a frame structure, which fits tightly to the side of the mobile device through the frame structure, thereby providing good protection and cushioning.

[0032] Furthermore, the slide groove 11 is located on the frame structure of the first frame body 1, and is used to provide an axially movable track for the magnetic attraction slider 3. The slide groove 11 is a through groove with a U-shaped cross section and an open end, and its opening is located at the contact surface between the first frame body 1 and the second frame body 2. The cantilever 31 extends from the opening of the slide groove 11 to extend toward the second frame body 2. The clamping portion 21 is a plate protruding from the frame structure of the second frame body 2. As an optional embodiment, a avoidance groove 22 can also be directly recessed on the second frame body 2 without the need for the clamping portion 21 to cooperate with it. The purpose of setting the avoidance groove 22 and the clamping portion 21 is to cooperate with the flexible hook portion 32 to clamp the second frame body 2.

[0033] Furthermore, the flexible hook 32, the cantilever 31 and the magnetic slider 3 are an integrally formed structure, and its material includes but is not limited to silicone, rubber, elastic plastic (such as TPE, TPR) and composite materials. The flexible hook 32 is intended to simplify the installation process of the locking structure through its elastic deformation characteristics.

[0034] In addition, the magnetic slider 3 is a magnetic buckle. As another optional embodiment, the magnetic slider 3 can also have magnetic force itself, eliminating the step of embedding the third magnet 33 inside it, improving the compactness of the overall structure and reducing the processing cost. The first magnet 12 and the second magnet 23 are used to move the third magnet 33 toward the direction close to the clamping portion 21, which can be achieved by placing the first magnet 12 at a position close to the clamping portion 22, and bringing the first magnet 12 and the third magnet 33 closer to each other with different poles to attract each other, and then placing the second magnet 23 at a position away from the clamping portion 21, and bringing the second magnet 23 and the third magnet 33 closer to each other with the same poles to repel each other, or adjusting the same poles, different poles and corresponding positions. No excessive restrictions are made here, as long as the first magnet 12 and the second magnet 23 move the third magnet 33 toward the direction close to the clamping portion 21 by adsorption or repulsion.

[0035] In this embodiment, one end of the first magnet 12 is located at one end of the third magnet 33, and the first magnet 12 and the third magnet 33 attract each other, so that the locking structure between the two frames can maintain a firm connection in the locked state. At the same time, one end of the second magnet 23 is located at the end of the third magnet 33 away from the first magnet 12, and the third magnet 33 and the first magnet 12 repel each other, further improving the reliability of the locking structure. When the magnetic attraction slider 3 is pushed to release the locking state between the flexible hook portion 32 and the clamping portion 21, under the action of the first magnet 12 and the second magnet 23, the pushing process has a certain damping feeling, thereby avoiding unlocking due to user error, thereby improving user experience.

[0036] The present invention is described in more detail below by way of examples. However, the following examples are merely illustrative and should not be construed as limiting the scope of the present invention. Obviously, those skilled in the art may make any changes, improvements or modifications without violating the spirit of the present invention.

[0037] See also Figures 1 to 5 This example proposes a working principle of a locking structure. When the first frame 1 and the second frame 2 are assembled, the frame structures of the first frame 1 and the second frame 2 fit each other. At this time, the clamping portion 21 of the second frame 2 squeezes the flexible hook 32 extending from the first frame 1. Under the downward squeezing force of the clamping portion 21, the flexible hook 32 and the cantilever 31 are elastically deformed to a certain extent. Once the clamping portion 21 is completely pressed between the flexible hook 32 and the cantilever 31, the flexible hook 32 loses the continuous force and returns to its original shape. At this time, the flexible hook 32 is hooked on the clamping portion 21 and located in the avoidance groove 22, completing the rapid clamping and locking of the first frame 1 and the second frame 2. After the locking process is completed, the third magnet 33 inside the magnetic slider 3 is pulled to the side of the slide groove 11 close to the clamping portion 21 under the adsorption action of the first magnet 12, so that the flexible hook 32 can stably maintain the clamping fit with the clamping portion 21.

[0038] When it is necessary to release the connection lock state between the first frame 1 and the second frame 2, it is only necessary to push the magnetic slider 3 to disengage the flexible hook 32 from the engagement with the clamping portion 21, and the second frame 2 can be removed. The clamping portion 21 is also provided with an avoidance groove 22 to prevent the flexible hook 32 from interfering with other structures during the activity and affecting the unlocking action. In addition, in the unlocked state, the third magnet 33 inside the magnetic slider 3 is pulled toward the side of the slide groove 11 close to the clamping portion 21 under the adsorption action of the first magnet 12, and the magnetic slider 3 is moved toward the side away from the clamping portion 21 by the external push-pull force provided by the user. At this time, the overall push-pull process has a certain damping feeling. At the same time, the second magnet 23 repels the third magnet 33 inside the magnetic slider 3, further improving the damping effect.

[0039] See also Figure 3 and Figure 5 In this embodiment, a guiding slope 32a is provided on the flexible hook portion 32 along the direction in which the clamping portion 21 is pressed downward. The guiding slope 32a is used to guide the clamping portion 21 to smoothly enter between the flexible hook portion 32 and the cantilever 31. By setting the guiding slope 32a, the friction resistance in the assembly process can be reduced, the assembly efficiency and reliability can be improved, and quick clamping and locking can be achieved.

[0040] See also Figures 2 to 5In this embodiment, the first frame 1, the second frame 2 and the magnetic attraction slider 3 are respectively provided with a first magnet slot 13, a second magnet slot 24 and a third magnet slot 34 for accommodating the first magnet 12, the second magnet 23 and the third magnet 33. By placing and fixing the magnets in their respective slots, they can be prevented from shifting or falling off during movement, thereby ensuring the effective transmission and action of the magnetic force.

[0041] See also Figure 3 to Figure 4 In this embodiment, a push plate portion 35 is extended from one side of the magnetic attraction slider 3, and an operation hole 14 for extending the push plate portion 35 is provided on the first frame 1, and the operation hole 14 is connected to the slide groove 11. By providing the operation hole 14 on the first frame 1, the user can apply force to the magnetic attraction slider 3 by pressing or pulling, so that the push plate portion 35 drives the magnetic attraction slider 3 to move. The cooperation between the push plate portion 35 and the operation hole 14 facilitates the user to operate the locking structure, thereby improving the convenience of operation of the structure.

[0042] See also Figures 3 to 5 In this embodiment, a limiting protrusion 36 is convexly provided on the side of the magnetic attraction slider 3 away from the push plate portion 35, and a limiting groove 15 for constraining the limiting protrusion 36 is provided on the first frame 1, and the limiting protrusion 36 is movably arranged in the limiting groove 15. Through the cooperation between the limiting protrusion 36 and the limiting groove 15, the movement range of the magnetic attraction slider 3 can be limited, and additional stability can be provided to ensure that the magnetic attraction slider 3 is constrained in the first frame 1 during assembly and movement, and is not easy to fall off or shift.

[0043] See also Figures 1 to 5 The utility model also proposes a mobile phone case, including a first frame body 1 and a second frame body 2, and the mobile phone case also includes any one of the locking structures described above. The specific structure of the locking structure refers to the above embodiment. Since the mobile phone case proposed by the utility model includes all schemes of all embodiments of the above locking structure, it has at least the same technical effect as the locking structure, which will not be elaborated here one by one.

[0044] See also Figure 2 In this embodiment, the mobile phone case further includes a card block 16 arranged on the first frame body 1 and a card slot 25 arranged on the second frame body 2 and cooperating with the card block 16 .

[0045] See also Figure 2 In this embodiment, the card block 16 is provided in plurality, and the number of the card slots 25 corresponds to the card block 16. The cooperation between the card block 16 and the card slot 25 plays a guiding role in the connection between the two frames, and further improves the strength of the connection and locking.

[0046] See also Figure 2In this embodiment, the first frame 1 and the second frame 2 are respectively provided with a first sinking groove 17 and a second sinking groove 26 for placing magnets. The magnets in the first sinking groove 17 and the second sinking groove 26 are attracted to each other, so as to further fix the first frame 1 and the second frame 2. The multi-layer fixing structure cooperates with each other, and the mobile phone case is close to the mobile phone body, so as to better fix the mobile phone and enhance the stability of the mobile phone case. In addition, by providing the card block 16, the card slot 25 and the sinking groove, an additional locking / connecting structure is provided for the first frame 1 and the second frame 2, so as to avoid the mobile phone case still being able to fix the mobile phone body when a single locking structure is damaged and fails.

[0047] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
