[0001] This utility model relates to the field of protective case technology, specifically a mid-frame and a mobile phone case. Background Technology

[0002] In today's society, mobile phones have become an indispensable electronic product. With the powerful functions of mobile phones and the pursuit of a slim and lightweight feel, mobile phone cases have become an essential part of protecting mobile phones. Among them, mobile phone cases with stands have expanded the original function of protecting mobile phones to meet more needs.

[0003] Existing protective cases still have some problems: most protective cases are one-piece structures. Although they have a certain protective function, in actual use, the traditional full-coverage shell structure can easily obstruct the airflow on the back of the phone, making it difficult to effectively dissipate the heat generated by the phone during operation.

[0004] Therefore, there is an urgent need for a mid-frame and phone case to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a mid-frame and a phone case to solve the problem that full-coverage shells are difficult to effectively dissipate heat during phone operation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a middle frame, including a frame body, wherein the middle part of the frame body has an opening forming a ring-shaped hollow contour structure, the inner wall of the opening is set as a flat area, and the opposite two ends of the opening extend inward to form a first edge and a second edge for support and positioning.

[0007] As a preferred embodiment of the middle frame, the frame surface corners are provided with buffer portions, which are used to absorb external impact forces.

[0008] As a preferred embodiment of the middle frame, the thickness of the buffer portion gradually decreases from the middle to the outer edge.

[0009] As a preferred embodiment of the middle frame, the corner sidewall of the frame is provided with a support foot, which is used to create a gap between the frame and the contact surface when the frame is placed.

[0010] As a preferred option for the mid-frame, it also includes an inner skeleton, which is embedded inside the frame and matches its shape and contour.

[0011] As a preferred embodiment of the mid-frame, the inner frame has a notch on the corner sidewall corresponding to the support leg, and the buffer part is embedded in the notch.

[0012] As a preferred embodiment of the mid-frame, the flat area is provided with anti-slip texture to prevent the mobile phone from sliding.

[0013] As a preferred embodiment of the mid-frame, the frame surface is provided with charging port, audio port and several button positions, and the corresponding positions of the inner skeleton are provided with hollow structures.

[0014] A mobile phone case includes a back panel and a middle frame, wherein a groove is provided on the side of the flat area adjacent to the second edge;

[0015] The flat area has an extension wall extending adjacent to the second edging, and the second edging and the extension wall form a step;

[0016] A slot is formed on the inner wall of the second edge;

[0017] One side edge of the back plate is provided with a protruding edge for engaging with the groove and the extension wall, and the surface of the protruding edge is provided with a protruding block for engaging with the slot.

[0018] As a preferred embodiment of a mobile phone case, the back panel is provided with a mounting groove and a magnetic block, the magnetic block being embedded in the mounting groove and used for magnetic connection with an external device.

[0019] The beneficial effects of this utility model are as follows: The open design and the flat area on the inner wall of the open design allow for the mounting of the phone body. The opposite edges of the open design extend inwards to form a first and a second edging, respectively, providing restraint and support around the phone, preventing it from wobbling within the frame, and avoiding damage due to collisions or movement, thus providing reliable protection.

[0039] Example 1

[0040] In one embodiment of this utility model, such as Figure 1-3 As shown, a middle frame is provided, including a frame body 1. The middle part of the frame body 1 has an opening 2 to form an annular hollow outline structure. The inner wall of the opening 2 is set as a flat area. The opposite two ends of the opening 2 extend inward to form a first edge 3 and a second edge 4 for support and positioning.

[0041] The mid-frame provided by this utility model, through an opening 2 and a flat area on the inner wall of the opening 2, accommodates the main body of the mobile phone. The opposite edges of the opening 2 extend inward to form a first edging 3 and a second edging 4, respectively, to limit and support the perimeter of the mobile phone, preventing it from shaking within the mid-frame and avoiding damage due to collisions or movement, thus providing reliable protection. The annular hollow contour structure formed by the opening 2, while ensuring protective performance, leaves the back of the mobile phone unobstructed, significantly improving heat dissipation and reducing the impact of heat buildup on device operation. Furthermore, this mid-frame can be independently fitted onto the surface of the mobile phone, facilitating assembly and disassembly while preserving the original design of the mobile phone to the greatest extent, combining practicality and visual appeal.

[0042] Preferably, the frame 1 can be a rounded rectangle, a shape that matches the shape of most smartphones, ensuring good adaptability and aesthetics. In other embodiments, the frame 1 can also be an ellipse, a racetrack shape, or other irregular shapes.

[0043] Preferred, such as Figure 4 The frame 1 has a protruding buffer section 5 at the corner of its frame surface. This corner placement maximizes the impact-bearing area. The buffer section 5 is integrally formed with the frame 1, which not only improves overall strength and structural stability but also simplifies the manufacturing process and reduces production costs. The buffer section 5 acts as a buffer and absorbs energy when the frame is subjected to external impacts. Especially during drops or collisions, it effectively absorbs and disperses impact energy, thereby reducing direct damage to the phone and improving the safety and reliability of the device.

[0044] Furthermore, the thickness of the buffer section 5 gradually decreases from its center to its edge. This gradient thickness change allows the buffer area to produce a more uniform deformation distribution when subjected to force, which enhances its impact resistance and avoids the risk of localized fracture caused by stress concentration.

[0045] Preferred, such as Figure 2 and Figure 3 The corner sidewall of the frame 1 is provided with at least one support leg 6. This support leg 6 is used to maintain a certain gap between the bottom of the middle frame and the contact surface when the middle frame is placed horizontally on a table or other contact surface. This not only effectively prevents the surface of the middle frame from directly contacting the table and causing scratches and damage, but also creates a ventilation gap between the middle frame and the contact surface, improving air circulation and thus enhancing heat dissipation efficiency and preventing the equipment from overheating due to prolonged use.

[0046] In a preferred embodiment of this utility model, such as Figure 2 The middle frame includes an outer frame 1 made of liquid silicone and an inner skeleton 7 embedded inside it and matching its shape and contour. The inner skeleton 7 is preferably made of PC material, so that the frame 1 has excellent elasticity and comfortable feel while having sufficient structural support and load-bearing capacity.

[0047] Specifically, such as Figure 2 and Figure 3 The inner frame 7 has at least one notch 8 on the corner sidewall corresponding to the support leg 6, and the buffer part 5 is inserted into the notch 8. The addition of the notch 8 not only allows the buffer part 5 to fit in, improving the connection stability between the middle frame and the inner frame 7, but also increases the thickness of the local buffer part 5, giving it a larger deformation space.

[0048] When the mid-frame is placed on a flat surface or during a drop, the support leg 6 acts as the first point of contact, causing the buffer part 5 to bear the main impact force. Because the buffer part 5 has a greater material thickness in this area, it can absorb more energy during the stress process, thus improving the overall shock absorption performance.

[0049] This type of frame has anti-slip texture 9 in the flat area, which is used to prevent the mobile phone from sliding.

[0050] Specifically, such as Figure 7 The anti-slip texture 9 is composed of several base grooves 901, which are evenly distributed in the flat area. The long diagonal of each base groove 901 is parallel to the direction of the opening 2, and the short diagonal of each base groove 901 is perpendicular to the direction of the opening 2. Secondary grooves 902 are located at the intersections of the base grooves 901, and the depth of the base grooves 901 is shallower than the depth of the secondary grooves 902. The difference in groove depth provides additional friction, ensuring the durability and reliability of the anti-slip effect.

[0051] Preferably, the frame 1 has charging port, audio port and several button positions on its frame surface, and the inner frame 7 has hollow structure at the corresponding positions to achieve precise alignment with the interface and button area of ​​the mobile phone body.

[0052] Example 2

[0053] In one embodiment of this utility model, such as Figure 4-10 As shown, a mobile phone case is provided, including a back panel 10 and a middle frame. A groove 11 is provided on one side of the flat area adjacent to the second edge 4. An extension wall extends from the flat area adjacent to the second edge 4, and the second edge 4 and the extension wall form a step. A slot 12 is formed on the inner wall of the second edge 4. A protruding edge 13 is provided on one side edge of the back panel 10 for engaging with the groove 11 and the extension wall. The surface of the protruding edge 13 is provided with a protrusion 14 for engaging with the slot 12.

[0054] The phone case provided by this utility model enhances the connection stability between the phone case and the phone by fitting the protruding edge 13 of the back plate 10 with the groove 11 of the middle frame and the extension wall, ensuring that the phone case does not loosen or fall off during daily use, thus providing a reliable protective foundation for the phone. The engagement of the protrusion 14 on the surface of the protruding edge 13 with the slot 12 improves the convenience of installation and removal.

[0055] In this embodiment, during installation, if... Figures 9-10 Users can simply align the protruding edge 13 with the groove rail 11 and the extension wall, and engage the protruding block 14 with the slot 12 to confirm that the installation is complete. When disassembling, the protruding block 14 can be easily disengaged from the slot 12 by applying appropriate force, thus enabling quick disassembly of the phone case and greatly improving the user experience.

[0056] Preferably, this utility model can be a protective case, which can be used not only to protect mobile phones, but also to protect tablets or other products.

[0057] Preferred, such as Figure 6The back panel 10 is provided with a mounting groove 15 and a magnetic block 16. The magnetic block 16 is embedded in the mounting groove 15 and is used for magnetic connection with external devices. The magnetic block 16 is a hidden embedded structure, which does not affect the overall appearance of the back panel 10 and avoids the risk of scratches that may be caused by exposed magnetic parts, thus balancing practicality and aesthetics.

[0058] Preferred, such as Figure 5 The back panel 10 is provided with a lens mounting hole 17, which is located in a position corresponding to the mobile phone camera area, ensuring that the normal use of the photography function is not affected when the middle frame and the back panel 10 are assembled together.

[0059] In addition, the edges of the lens mounting hole 17 are rounded and raised, which not only avoids scratching the lens but also improves the overall harmony of the appearance of the whole machine, combining practicality and aesthetics.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
