Description

Technical Field

[0001] This utility model belongs to the field of mobile phone casing technology, specifically a drop-resistant and protective mobile phone casing. Background Technology

[0002] With the rapid development of technology, the "tech beauty" industry has emerged as a new sector. Phone cases, as decorative items that protect or enhance the appearance of mobile phones, have become increasingly diverse with the evolution of mobile phones. Using a phone case can prevent damage from drops, collisions, and other accidents during daily use, especially to the screen and frame. However, current phone cases do not offer very good heat dissipation.

[0003] Reference CN207382397U discloses a drop-proof mobile phone case. The case has a drop-proof layer on its surface, an anti-vibration and drop-proof device inside, and side walls fixedly connected to the four sides. Leather pads are fixedly installed on the inner side of the side walls, and spring sheets are fixedly installed inside the side walls. The drop-proof layer is a frosted rubber coating. The anti-vibration and drop-proof device includes raised textures and raised balls, with the raised balls fixed at the intersections of the raised textures. However, the phone's heat dissipation is poor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a drop-resistant and protective mobile phone case with good heat dissipation effect.

[0005] To solve the above technical problems, this utility model provides a drop-resistant protective mobile phone shell, including a shell with multiple heat dissipation holes evenly drilled on the bottom surface of the shell in an array distribution. A waterproof and breathable membrane is attached to the inner side of the bottom surface, and multiple heat-conducting strips are evenly arranged on the waterproof and breathable membrane, avoiding the heat dissipation holes. Mounting blocks are set on the outer sides of the four corners of the shell, and drop-resistant components are set on the mounting blocks. The drop-resistant components are corner-shaped structures that fit with the corners of the mobile phone, and the corners are rounded. A waterproof strip is set at the camera opening on the bottom surface, and the waterproof strip is attached to the periphery of the camera of the mobile phone. A second waterproof strip is set around the top edge of the four sides of the shell, and the second waterproof strip is attached to the edge of the top surface of the mobile phone.

[0006] By adopting the above technical solution, anti-drop components are installed at the four corners of the shell, and a waterproof and breathable membrane is attached to the bottom. The heat of the phone is conducted to the surface of the shell through the heat conduction strip. The shell has an array of heat dissipation holes, and the shell is equipped with a three-layer thermal management structure, which makes the shell anti-drop while having a good heat dissipation effect.

[0007] Preferably, the diameter of the heat dissipation holes is 0.3mm-1.5mm.

[0008] By adopting the above technical solution and using heat dissipation hole diameters of 0.3mm-1.5mm, the structural strength of the outer shell is maintained while optimizing the air circulation environment and improving the heat conduction capacity of the phone case.

[0009] Preferably, the spacing between the heat dissipation holes is not less than 1.5 times the diameter of the heat dissipation holes.

[0010] By adopting the above technical solution, the hole spacing is not less than 1.5 times the diameter of the heat dissipation hole, which prevents stress concentration from causing the shell to crack.

[0011] Preferably, the waterproof strip one and waterproof strip two are made of silicone.

[0012] By adopting the above technical solution, the waterproof strip one at the camera opening is installed around the bottom of the phone's camera; the waterproof strip two on the top edge of the four sides of the casing is installed on the top edge of the phone. The waterproof strip one and the waterproof strip two are made of silicone material and fit completely with the surrounding area and edge, improving the waterproof performance of the casing.

[0013] Preferably, the impact-resistant component is made of a silicone layer and a steel plate, with the silicone layer disposed on the inner side of the steel plate and the silicone layer fitting against the outer corner of the outer shell.

[0014] By adopting the above technical solution, the outer steel plate of the silicone layer is scratch-resistant, preventing hard objects such as keys from directly scratching the silicone layer, and the silicone layer absorbs the impact energy when falling.

[0015] Preferably, the total thickness of the impact-resistant components is 2.5-5mm, and the thickness ratio of the silicone layer to the steel plate is between 1.5:1 and 3:1.

[0016] By adopting the above technical solution, the thickness ratio of silicone layer to steel plate of 1.5:1 to 3:1 can ensure that silicone layer provides sufficient cushioning, while steel plate has sufficient rigidity to achieve the synergistic effect of shock absorption and support.

[0017] Preferably, the mounting block is provided with mounting hole one, and the anti-drop component is provided with mounting hole two. The mounting block and the anti-drop component are fixedly installed by fasteners.

[0018] By adopting the above technical solution, when the anti-drop component wears or deforms due to long-term use, users only need to replace the anti-drop component, without having to scrap the entire phone case, thus reducing maintenance costs.

[0019] Preferably, the mounting hole is a screw hole, and the fastener is a screw with a cylindrical screw rod.

[0020] By adopting the above technical solution, the cylindrical screw type screw is easy to assemble and the materials are readily available.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model installs anti-drop components at the four corners of the shell, attaches a waterproof and breathable membrane to the bottom surface, conducts the heat of the phone to the surface of the shell through the heat conduction strip, and has an array of heat dissipation holes on the shell, thus configuring a three-layer thermal management structure for the shell, which makes the shell anti-drop while having a good heat dissipation effect.

[0023] 2. The diameter of the heat dissipation holes in this invention is 0.3mm-1.5mm, which maintains the structural strength of the outer shell while optimizing the air circulation environment and improving the heat conduction capacity of the phone case. The spacing between the heat dissipation holes is not less than 1.5 times the hole diameter to prevent stress concentration from causing the outer shell to crack.

[0024] 3. The impact-resistant component of this utility model is made of a silicone layer and a steel plate, with a total thickness of 2.5-5mm. The steel plate is attached to the outside of the silicone layer, and the thickness ratio of the silicone layer to the steel plate is between 1.5:1 and 3:1. This thickness ratio ensures that the silicone layer provides sufficient cushioning, while the steel plate has sufficient rigidity to achieve a synergistic effect of shock absorption and support.

[0030] like Figure 1As shown, the drop-resistant mobile phone casing includes a casing 1. Multiple heat dissipation holes 3 are evenly drilled on the bottom surface 2 of the casing 1. A waterproof and breathable membrane 4 is adhered to the inner side of the bottom surface 2. Multiple heat-conducting strips 5 are evenly arranged on the waterproof and breathable membrane 4, and the waterproof and breathable membrane 4 and the heat-conducting strips 5 are bonded together with adhesive. The heat-conducting strips 5 avoid the heat dissipation holes 3, and the phone conducts heat to the surface of the casing 1 through the heat-conducting strips 5. Mounting blocks 7 are set on the outer sides of the four corners 6 of the casing 1, and drop-resistant components 8 are set on the mounting blocks 7. The drop-resistant components 8 are corner-shaped structures that fit into the corners of the phone. The two sides of the drop-resistant components 8 are perpendicular to each other, and the corners are rounded. The rounded transition design transforms the impact force from sharp point contact to surface contact, reducing the stress concentration coefficient from 3-5 for right-angle structures to 1.2-1.5, and increasing the impact resistance by more than 200%. A waterproof baffle 12 is set at the camera opening 11 on the bottom surface 2. The waterproof baffle 12 is adhered to the waterproof and breathable membrane 4. Waterproof strip 12 is attached to the periphery of the bottom of the phone's camera; a second waterproof strip 14 is provided around the top edge of the four sides 13 of the outer casing 1, and the second waterproof strip 14 is attached to the edge of the top surface of the phone. This application installs anti-drop components 8 at the four corners of the outer casing 1, and a waterproof and breathable membrane 4 is attached to the bottom surface 2. The heat of the phone is conducted to the surface of the outer casing 1 through the heat conduction strip 5. The outer casing 1 has an array of heat dissipation holes 3, and the outer casing 1 is equipped with a three-layer thermal management structure, so that the outer casing 1 is not only anti-drop but also has a good heat dissipation effect.

[0031] like Figure 2 As shown, the heat dissipation holes 3 are arranged in an array, with a diameter of 0.3mm-1.5mm. While maintaining the structural strength of the outer shell 1, the air circulation environment is optimized, improving the heat conduction capacity of the phone shell. The spacing between the heat dissipation holes 3 is not less than 1.5 times the diameter of the heat dissipation holes 3 to prevent stress concentration from causing the outer shell 1 to crack.

[0032] Waterproof strip 12 and waterproof strip 2 14 are made of silicone. Waterproof strip 12 at the camera opening 11 is installed around the bottom of the phone's camera; waterproof strip 2 14 on the top edge of the outer casing 13 is installed on the top edge of the phone. Waterproof strip 12 and waterproof strip 2 14 are made of silicone and fit perfectly with the surrounding area and edge to improve the waterproof performance of the casing.

[0033] like Figure 3 As shown, the impact-resistant component 8 is made of a silicone layer 15 and a steel plate 16. The silicone layer 15 is disposed on the inner side of the steel plate 16, and the silicone layer 15 is attached to the outer side of the corner 6 of the outer shell 1. The outer steel plate 16 of the silicone layer 15 is scratch-resistant and prevents hard objects such as keys from directly scratching the silicone layer 15. The silicone layer 15 absorbs the impact energy when falling.

[0034] The total thickness of the impact-resistant component 8 is 2.5-5mm. The thickness ratio of the silicone layer 15 to the steel plate 16 is between 1.5:1 and 3:1. This thickness ratio ensures that the silicone layer 15 provides sufficient cushioning, while the steel plate 16 has sufficient rigidity to achieve the synergistic effect of shock absorption and support.

[0035] like Figure 4 As shown, mounting block 7 has mounting hole 9, and anti-drop component 8 has mounting hole 10. Mounting block 7 and anti-drop component 8 are fixedly installed by fastener 17. When anti-drop component 8 wears or deforms due to long-term use, the user only needs to replace anti-drop component 8, without having to scrap the entire phone casing, thus reducing maintenance costs. Users can also change the color of anti-drop component 8 according to different occasions, such as business meetings, outdoor sports, fashion parties, or moods. The steel plate 16 can be painted to avoid aesthetic fatigue due to a single appearance.

[0036] Mounting hole 9 is a screw hole, and fastener 17 is a screw with a cylindrical shank. Using a cylindrical screw to install the anti-drop component 8 is simple to assemble and the material is readily available.

[0037] Working principle: Under the action of the heat dissipation holes 3 drilled in an array on the outer shell 1 and the heat conduction strip 5 on the waterproof and breathable membrane 4 on the inner bottom surface of the outer shell 1, the heat conduction strip 5 avoids the heat dissipation holes 3, and the mobile phone conducts heat to the surface of the outer shell 1 through the heat conduction strip 5. With this three-layer thermal management structure, the outer shell 1 is not only drop-resistant, but also has a good heat dissipation effect.
