Description

Technical Field

[0001] This application relates to the field of electronic product protection equipment technology, and in particular to a shock-resistant and drop-proof protective shell structure. Background Technology

[0002] As smartphones become increasingly sophisticated (e.g., with image stabilization in cameras and narrow bezels on screens), protective cases that shield phones from drops and impacts have become mainstream accessories. Existing phone cases typically use hard or soft materials to directly wrap around the phone, providing cushioning protection through the material's energy absorption or deformation.

[0003] There is a Chinese patent, authorized number CN203986566U, which stamps evenly distributed outwardly convex arc-shaped strips on each outer side of a mobile phone case to improve the cushioning effect. However, in actual use, the arc-shaped strips extending from the outside of the phone case will affect the normal user experience. Therefore, this application proposes a shockproof and drop-proof protective case structure to solve this technical problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a shock-resistant and drop-proof protective shell structure to solve the problems in the background technology.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a shockproof and drop-proof protective case structure, including a protective case body for protecting mobile devices, wherein a placement cavity for installing mobile devices is provided inside the protective case body, and an elastic suspension buffer is installed on the side wall of the placement cavity to prevent direct contact between the mobile devices and the protective case body.

[0006] By adopting the above technical solution, when the mobile device is placed inside the protective case, the elastic suspension buffer on the side of its placement cavity wraps around and supports it, maintaining a tiny physical gap between the phone and the hard protective case. This gap allows the phone to remain in a suspended state during daily use. For everyday bumps, friction, and minor vibrations, this structure effectively prevents the phone from directly contacting the hard case, thus preventing damage to the delicate electronic device's appearance or function. When a drop or severe impact occurs, the external impact force is first absorbed and dispersed by the high-strength protective shell. The remaining impact energy is transferred through the protective shell to the elastic suspension buffer. This component undergoes controllable and recoverable elastic deformation, converting the violent impact force into its own deformation energy, which is then absorbed and dissipated. This process greatly reduces the impact force ultimately transmitted to the phone.

[0007] Furthermore, the cross-section of the elastic suspension buffer is wavy, and multiple sets of the elastic suspension buffer are provided and distributed on each side wall around the placement cavity.

[0008] By adopting the above technical solutions, the wave-shaped structure can respond to impacts from different directions through its complex curved surface deformation. Whether it is a frontal, lateral, or oblique impact, it can absorb energy through the structure's compression deformation, bending deformation, and torsional deformation, achieving all-round seismic protection, effectively coping with the complex and varied drop angles in daily life, and eliminating blind spots in protection.

[0009] Distributing multiple sets of wave-shaped buffers on the side walls around the placement cavity means that the entire frame of the phone can be elastically supported, rather than relying on just a few isolated points, which creates a full-area contact and uniform buffering effect.

[0010] Furthermore, a button protective sleeve for protecting the buttons of the mobile device is fixedly provided on the outer side of the main body of the protective shell, and the elastic floating buffer is spaced around the button protective sleeve.

[0011] By adopting the above technical solution, this application achieves a synergistically enhanced protective effect by fixing a soft button protective cover on the outside and spatially spacing it with the elastic floating buffer on the inside. The button protective cover provides dedicated flexible protection for the phone buttons and effectively prevents dust.

[0012] The spaced layout ensures that the button's active area and the elastic buffer zone do not interfere with each other, guaranteeing both a clear and sensitive button press feel and maximizing the elastic buffer's deformation energy absorption efficiency. Simultaneously, this layout enhances the structural integrity of the area surrounding the buttons, improving the overall strength and reliability of the protective case, thus achieving seamless protection from the frame to the buttons.

[0013] Furthermore, the elastic suspension buffer is also installed on the inner wall of the placement cavity.

[0014] By adopting the above technical solution and further extending the wave-shaped elastic suspension buffer to the inner wall of the placement cavity, a comprehensive upgrade of the protection system is achieved. This means that the elastic buffer system is no longer limited to protecting the side frame of the phone, but also covers the entire back area of ​​the phone. When the back of the protective case is impacted, the elastic buffer on the inner wall can immediately play its role, effectively absorbing the impact energy through the compression deformation of its wave-shaped structure, preventing the impact force from being directly transmitted to the back panel of the phone, and greatly reducing the risk of damage to the back panel and internal precision components due to back impact.

[0015] Furthermore, the elastic suspension buffer is made of a material with high elasticity, high energy absorption, and good recovery performance, specifically, it can be made of fiberboard, carbon fiber board, Kevlar sheet, etc. In summary, this application includes the following beneficial technical effects: by setting a corrugated elastic suspension buffer on the inner wall and side wall, a stable physical gap is formed between the mobile phone and the protective case body, achieving all-round "suspended" protection, effectively isolating daily bumps and friction, and avoiding scratches and minor damage.

[0016] In the event of a drop or impact, the main body of the protective case first absorbs and disperses the impact, while the remaining energy is efficiently absorbed by the elastic buffer through the compression, bending and shear deformation of the wave structure, greatly reducing the impact force transmitted to the mobile phone and providing dual protection.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Example, refer to Figure 1 as well as Figure 2 A shockproof and drop-proof protective case structure includes a protective case body 1 for protecting a mobile phone device. The protective case body 1 has a placement cavity 11 for installing the mobile phone device inside. An elastic suspension buffer 2 is installed on the side wall of the placement cavity 11 to prevent the mobile phone device from directly contacting the protective case body 1. The elastic suspension buffer 2 is made of a material with high elasticity, high energy absorption and good recovery performance, specifically it can be made of fiberboard, carbon fiber board, Kevlar sheet, etc.

[0021] When the mobile phone is placed into the protective case body 1, the elastic suspension buffer 2 on the side of its placement cavity 11 wraps around and supports it, maintaining a small physical gap between the phone and the hard protective case body 1. This gap allows the phone to float during daily use. For everyday bumps, friction, and minor vibrations, this structure can effectively prevent the phone from directly contacting the hard case, thereby preventing scratches and minor damage.

[0022] When a drop or severe impact occurs, the external impact force is first absorbed and dispersed by the high-strength protective shell body 1. The remaining impact energy is transferred to the elastic suspension buffer 2 through the protective shell body 1. This component undergoes controllable and recoverable elastic deformation, converting the violent impact force into its own deformation energy, which is then absorbed and dissipated. This process greatly reduces the impact force that is ultimately transmitted to the mobile phone.

[0023] In this embodiment, the elastic suspension buffer 2 has a wavy cross-section. Multiple sets of elastic suspension buffer 2 are provided and distributed on the side walls surrounding the placement cavity 11. In this application, the elastic suspension buffer 2 can be fixedly connected to the protective shell body through various methods such as adhesive bonding and snap-fitting. When subjected to impacts from different directions, the wavy structure can respond through its complex curved surface deformation. Whether it is a frontal, lateral, or oblique impact, it can absorb energy through structural compression deformation, bending deformation, and torsional deformation, achieving comprehensive seismic protection and effectively coping with the complex and varied drop angles in daily life, eliminating blind spots in protection.

[0024] Distributing multiple sets of wave-shaped buffers on the side walls around the placement cavity 11 means that the entire frame of the phone can be elastically supported, rather than relying on just a few isolated points, which creates a full-area contact and uniform buffering effect.

[0025] In this embodiment, a button protective sleeve 12 for protecting the buttons of a mobile phone is fixedly disposed on the outer side of the protective shell body 1, and elastic floating buffer members 2 are spaced around the button protective sleeve 12. This application achieves a synergistic and enhanced protection effect by fixing a soft button protective sleeve 12 on the outer side and spatially spacing it with the elastic floating buffer members 2 on the inner side. The button protective sleeve 12 provides dedicated flexible protection for the mobile phone buttons, effectively preventing dust and scratches.

[0026] The spaced layout ensures that the button's active area and the elastic buffer zone do not interfere with each other, guaranteeing both a clear and sensitive button press feel and maximizing the elastic buffer's deformation energy absorption efficiency. Simultaneously, this layout enhances the structural integrity of the area surrounding the buttons, improving the overall strength and reliability of the protective case, thus achieving seamless protection from the frame to the buttons.

[0027] The elastic suspension buffer 2 is also installed on the inner wall of the placement cavity 11. By further extending the corrugated elastic suspension buffer 2 to the inner wall of the placement cavity 11, a comprehensive upgrade of the protection system is achieved. This means that the elastic buffer system is no longer limited to protecting the side frame of the phone, but extends the protection to the entire back area of ​​the phone. When the back of the protective case is impacted, the elastic buffer on the inner wall can immediately play its role, effectively absorbing the impact energy through the compression deformation of its corrugated structure, preventing the impact force from being directly transmitted to the back panel of the phone, and greatly reducing the risk of damage to the back panel and internal precision components of the phone due to back impact.

[0028] Specific implementation process: When the protective case is accidentally dropped or impacted, if it lands on its side, the high-strength main body 1 of the protective case first absorbs and disperses most of the initial impact force. The remaining impact energy is transferred to the wave-shaped elastic suspension buffer 2 on the side wall. The buffer 2, through its wave structure, is compressed and flattened to generate controllable elastic deformation, efficiently converting the impact force into deformation energy and absorbing and dissipating it, thereby significantly reducing the impact transmitted to the phone. At the same time, the button protective sleeve 12, which is set on the outside of the protective case and spaced apart from the internal elastic buffer, provides dedicated flexible cushioning and sealing dustproof for the physical buttons on the side. Its spaced layout ensures that the button feel is clear and sensitive and does not interfere with the main cushioning system. If the back lands, the elastic buffer installed on the inner wall of the placement cavity 11 directly plays its role, absorbing the impact energy from the back through the same compression deformation, preventing damage to the phone's back panel and internal components.

[0029] After the mobile device is placed in the protective case, a small but appropriate physical gap is maintained between the device and the case body. This ensures that the phone will not come into direct contact with the case body due to slight vibrations or displacement during daily use, thus avoiding scratches and minor damage. At the same time, it provides sufficient deformation space for the elastic suspension buffer when the phone is dropped, so as to effectively absorb and dissipate impact energy. The preferred range for this gap is 0.1mm to 0.5mm, which achieves the best balance between protection and ease of use.

[0030] At the same time, the setup must also take into account the ease of product installation and removal, ensuring that users can operate it easily and that the phone will not be scratched due to friction of materials during the installation process.

[0031] After the impact, all the deformed elastic suspension buffers 2 automatically return to their original shape under their material properties, preparing for the next impact. This forms a three-dimensional, omnidirectional, and recyclable shock-absorbing and drop-proof protection system from the frame to the buttons, from the side walls to the back.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
