Description

Technical Field

[0001] This utility model relates to the field of mobile phone case technology, and in particular to a drop-proof smart protective case for mobile devices. Background Technology

[0002] With the rapid development of modern communication technology, smartphones have become indispensable tools in people's daily lives. To protect phones from physical damage and provide a personalized look, a wide variety of phone cases have emerged on the market. With innovations in display technology, e-ink screens utilize electronic ink display technology, which can print display elements on various surfaces, including curved plastics, polyester films, paper, and even fabrics, just like traditional ink. Unlike traditional paper, e-ink screens can change color and display dynamic images when powered on. While e-ink screens offer low power consumption and a visually close-to-paper reading experience, their vulnerability to physical impact is a significant issue. Most existing phone cases on the market focus on scratch resistance and impact reduction, but solutions specifically designed to protect the sensitive component—the e-ink screen—remain insufficient. When a phone is accidentally dropped, the resulting vibration can directly affect the internal chip, thus impacting the e-ink screen's functionality, leading to display failure or long-term damage. Therefore, developing a phone case that effectively protects the internal chip from physical impact is crucial for ensuring the normal operation of this high-tech display device and extending its lifespan.

[0003] Therefore, a smart protective case for mobile devices is proposed to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a smart protective case for mobile devices that is designed to solve the problem that existing phone cases cannot effectively protect the internal chips from physical damage when they are subjected to impact.

[0005] To achieve the above-mentioned utility model objectives, this utility model proposes a drop-proof smart protective case for mobile devices, including a protective case with a receiving groove for placing a mobile phone, a protrusion at the edge of the protective case, a mounting plate, and a display device. The mounting plate has a mounting groove for accommodating the display device, and a cushioning element is provided in the mounting groove.

[0006] Furthermore, at least one end of the cross-section at the top and bottom of the protective shell is larger than the cross-sections on the left and right sides of the protective shell.

[0007] Furthermore, the upper and lower edges of the mounting groove extend toward the upper and lower edges of the protective shell, respectively, such that the height of the upper edge of the mounting groove is above the upper inner wall of the protective shell, and the height of the lower edge of the mounting groove is below the lower inner wall of the protective shell.

[0008] Furthermore, the inner wall of the protective shell is provided with ribs for shock absorption.

[0009] Furthermore, the upper and lower end walls of the protective shell are provided with raised edges for drop protection.

[0010] Furthermore, the mounting slot is also provided with an NFC antenna and a connection component. The two ends of the connection component are respectively connected to the NFC antenna and the display device. The connection component is used to electrically connect the NFC antenna to the display device or to separate the NFC antenna from the display device.

[0011] Furthermore, the connection component includes: a ribbon cable, a connection terminal, and a connector. One end of the ribbon cable is electrically connected to the NFC antenna, and the other end of the ribbon cable is connected to the connection terminal. The connection terminal is located at the end of the ribbon cable away from the NFC antenna. One end of the connector is electrically connected to the display device, and the other end of the connector is plugged into or detached from the connection terminal.

[0012] Furthermore, a positioning boss is provided on the back of the protective shell, and a bracket is provided on the positioning boss, with the positioning boss hinged to the bracket.

[0013] Beneficial effects:

[0014] This utility model discloses a drop-proof smart protective case for mobile devices, including a buffer and protrusions at the edge of the case. Since the internal chip is highly sensitive to impacts, the vibrations from a drop can affect its performance. Therefore, the buffer is designed to reduce the stress on the display device caused by the drop. Multiple protrusions are also provided at the edge of the case. These protrusions form an additional protective layer around the edge of the phone and increase friction between the hand and the case, providing a better grip and making the phone feel more stable, reducing the likelihood of slipping. The buffer and the protrusions work together to provide a dual protection mechanism. The buffer absorbs and disperses impact, protecting sensitive internal components such as the e-ink screen and internal chips. Simultaneously, the protrusions form an additional protective layer at the edge of the case, effectively preventing direct impact to the core components, especially when the phone is dropped from the side or corner.

[0038] Reference Figures 1 to 8The utility model discloses a drop-proof smart protective case for mobile devices, including a protective case 100, wherein the protective case 100 is provided with a receiving groove 110 for placing a mobile phone 120, characterized in that the protective case 100 has a protrusion at its edge, and also includes a mounting plate 300 and a display device 200, wherein the mounting plate 300 has a mounting groove 310 for accommodating the display device 200, and a cushioning element is provided in the mounting groove 310.

[0039] At least one end of the cross-section of the upper and lower ends of the protective shell 100 is larger than the cross-section of the left and right sides of the protective shell 100. When the mobile phone 120 is placed into the receiving groove 110, the plane of the mobile phone 120 forms a first buffer part 130 and a second buffer part 140 with the upper and lower end walls and the left and right side walls, respectively. The distance between the first buffer part 130 and the plane of the mobile phone 120 is greater than the distance between the second buffer part 140 and the plane of the mobile phone 120.

[0040] The upper and lower edges of the mounting groove 310 extend toward the upper and lower edges of the protective shell 100, respectively, such that the height of the upper edge of the mounting groove 310 is above the upper inner wall of the protective shell 100, and the height of the lower edge of the mounting groove 310 is below the lower inner wall of the protective shell 100.

[0041] In this embodiment, in order to reduce the stress on the display device 200 caused by the fall of the protective shell 100, a buffer is provided in the mounting groove 310 between the back plate 700 and the display device 200. In one embodiment, the cushioning element is foam, which can be high-elastic PORON foam. The front and back sides of the foam can be glued to the bottom surface of the mounting groove 310 and the display device 200 respectively. In addition, the protective case 100 has multiple protrusions at its edge. The protrusions can form an additional protective layer at the edge of the phone 120. On the one hand, when the phone 120 is accidentally dropped, the protrusions can contact the ground first, dispersing the impact force, thereby reducing the force directly transmitted to the edge of the phone 120 and reducing the risk of damage to the phone 120. The protrusions can increase the structural strength of the edge of the protective case 100, making it more able to withstand the impact of drops and reducing cracks or damage caused by drops. On the other hand, the protrusions can increase the friction between the hand and the protective case 100, providing a better grip and making the user feel more secure when holding the phone 120, reducing the possibility of the phone 120 slipping. Since the protrusions increase friction, even when the hands are wet or sweaty, the risk of the phone 120 slipping can be reduced, improving the safety of using the phone 120. The protrusions can be made of materials such as silicone or rubber.

[0042] The wall thickness at the top and bottom of the protective cover is greater than that on the left and right sides. Additionally, to improve signal strength and enhance device compatibility, resulting in stronger signal transmission capabilities and the ability to interact with NFC devices of various sizes and shapes, the area of ​​the NFC antenna 400 has been increased. Figure 8 As shown, the upper end of the NFC antenna 400 is bent downwards and extended at an angle b. Correspondingly, the mounting groove 310 on the back of the protective shell 100 also extends outwards along the increased wall thickness and extends upwards at an angle a to accommodate the increased NFC antenna 400.

[0043] The display device 200 includes an e-ink screen and a color screen. In order to meet the interaction needs with NFC devices of various sizes and shapes, it was decided to adopt a larger area NFC antenna 400 to improve signal transmission capability and power support, especially to support large area e-ink displays.

[0044] By making the wall thickness at the top and bottom of the protective cover greater than that on the left and right sides, two reasons are presented. First, the increased area of ​​the NFC antenna 400 necessitates a corresponding increase in the installation space within the protective cover, which is achieved by increasing the wall thickness at the top and bottom. This not only provides sufficient space for the large-area NFC antenna 400 to mount, but also maintains the overall size and portability of the protective cover. The thickened top and bottom walls not only provide the necessary space for mounting the large-area NFC antenna 400, but also enhance the structural strength of the protective cover, providing better drop and impact protection.

[0045] When designing this drop-proof protective cover, the primary consideration was the need to protect the sensitive internal components of the phone 120, especially the NFC antenna 400 and the display device 200. As a key component for communication, the NFC antenna 400, with its increased area, is more susceptible to vibrations from drops. To mitigate this impact, the wall thickness at the top and bottom of the protective cover 100 was increased. This not only provides stronger physical protection when the phone 120 is dropped, but also creates a larger buffer zone through the thickened end walls, effectively absorbing impact and reducing vibration damage to the NFC antenna 400. Furthermore, the display device 200 is a relatively fragile display technology, easily damaged by physical impacts. The design of the protective cover 100 also helps protect the display device 200. This design reduces the failure rate caused by drops or impacts during daily use, extending the device's lifespan. At the same time, the structure of the protective cover 100 also supports the functional expansion of the NFC antenna 400, allowing the antenna area to be increased without increasing the risk of damage.

[0046] The inner wall of the protective shell 100 is provided with ribs 150 for shock absorption.

[0047] This design not only focuses on reducing the impact of vibration on the antenna, but also on protecting the mobile phone 120 and reducing the damage to the mobile phone 120 when dropped. The protective case 100 includes a frame 600 and a back panel 700. The frame 600 and the back panel 700 are integrally formed. The frame 600 is rectangular. Two ribs 150 are provided on the inner walls of the upper and lower ends of the frame 600. This design helps to enhance the overall strength of the protective case. When the mobile phone 120 is impacted, this design can absorb and disperse the impact force, reducing damage to the internal components of the mobile phone 120.

[0048] The upper and lower end walls of the protective shell 100 are provided with protruding edges 160 for drop protection.

[0049] The four corners of the frame 600 are provided with raised edges 160, which helps to disperse and absorb impact forces from various angles. When the phone 120 is accidentally dropped from a height, the raised edges 160 can effectively transfer and disperse the impact force, reducing the impact force directly acting on the plane and internal components of the phone 120. This design helps to protect the sensitive components inside the phone 120 and the protective cover, such as the internal chip, display device 200 and NFC antenna 400 of the phone 120, reducing the possibility of damage.

[0050] The protective shell 100 includes a frame 600 and a back plate 700, and the back plate 700 and the frame 600 are detachably connected.

[0051] The mounting slot 310 is also provided with an NFC antenna 400 and a connecting component 500. The two ends of the connecting component 500 are respectively connected to the NFC antenna 400 and the display device 200. The connecting component 500 is used to electrically connect the NFC antenna 400 to the display device 200 or to separate the NFC antenna 400 from the display device 200.

[0052] The connection component 500 includes: a ribbon cable 510, a connection terminal 520, and a connector 530. One end of the ribbon cable 510 is electrically connected to the NFC antenna 400, and the other end of the ribbon cable 510 is connected to the connection terminal 520. The connection terminal 520 is located at the end of the ribbon cable 510 away from the NFC antenna 400. One end of the connector 530 is electrically connected to the display device 200, and the other end of the connector 530 is plugged into or detached from the connection terminal 520.

[0053] The display device 200 is disposed on the back of the protective case 100. The display device 200 enables the display of text or patterns on the back of the protective case 100. In one embodiment, the operation of the display device 200 in the protective case does not require any external connection cable or tail plug. When in use, the main control program is driven by NFC coil coupling technology to realize data transmission and clearly display the transmitted content. No built-in battery or Bluetooth connection is required. The picture on the protective case can be changed at any time, truly realizing wireless transmission.

[0054] When the e-ink screen is working, it wirelessly connects to the NFC antenna 400 built into the phone 120 via the NFC antenna 400 inside the protective case 100. This allows the e-ink screen to draw power from the phone 120 through the NFC antenna 400, eliminating the need for an internal power supply within the e-ink screen. The protective case only draws a small amount of power from the phone 120 via NFC when transferring new images. After the transfer is complete, the e-ink screen does not require power to maintain the display. The ink capsule molecules are pushed to different positions by the control of positive and negative charges. When the current stops, the ink capsule molecules are fixed in their current positions. Therefore, the display does not require power and the power demand on the phone 120 is very small and negligible.

[0055] The connection component 500 enables the separation of the NFC antenna 400 on the protective case 100 from the e-ink screen, so that different NFC antennas 400 can be combined with the e-ink screen through the same connection component 500, thus enabling the NFC e-ink screen protective cover to be compatible with different models of mobile phones 120.

[0056] Specifically, to prevent the e-ink screen, connection terminal 520, and connector 530 from protruding outwards from the back of the protective shell 100, a mounting plate 300 is provided on the back of the protective shell 100. The mounting plate 300 has mounting slots 310 for mounting the display device 200, connection terminal 520, and connector 530. To enable the separation or connection of the NFC antenna 400 and the display device 200 for electrical connection, the connection component 500 includes a ribbon cable 510, a connection terminal 520, and a connector 530. One end of the ribbon cable 510 is electrically connected to the NFC antenna 400, and the connection terminal 520 is located on the back of the protective shell 100. At the end of the ribbon cable 510 away from the NFC antenna 400, a connector 530 is disposed on the back of the protective housing 100 and electrically connected to the display device 200. The connector 530 can be plugged into or detached from the connection terminal 520 to realize the electrical connection between the NFC antenna 400 and the display device 200 or to disconnect the electrical connection between the NFC antenna 400 and the display device 200. In one embodiment, the display device 200 includes an electronic paper display device 200 and a control circuit board 800 electrically connected to the electronic paper display device 200. The connector 530 is patched or soldered onto the control circuit board 800 and electrically connected to the control circuit board 800.

[0057] Optionally, the protective case 100 includes a frame 600 and a back panel 700, which are detachably connected. The receiving groove 110 is formed by the frame 600 and the back panel 700. In one embodiment, a limiting edge 610 is provided on the side wall of the frame 600, and the limiting edge 610 and the inner side wall of the frame 600 form a slot. The edge of the back panel 700 is engaged into the slot. In terms of case design, the e-ink screen back panel 700 and the mobile phone 120 frame 600 adopt a separate design, allowing users to not only freely change the pattern on the e-ink screen, but also customize it according to their personal preferences. The protective cover's frame has been replaced; specifically, the frame 600 is made of PC material, while the back panel 700 is made of tempered glass. PC material is a more robust and durable material with excellent impact resistance, better protecting the device during daily use. It doesn't yellow over time, has a delicate feel, and rounded edges for added protection. Tempered glass, used as the back panel 700 material, has extremely high transparency and excellent wear resistance, providing a clear visual experience. Simultaneously, its high hardness effectively resists scratches and wear during daily use, protecting the e-ink screen from damage. Additionally, a camera unit is integrally formed at the top of the frame 600, extending from the frame 600 away from the mounting plate 300.

[0058] In this embodiment, to achieve the basic functions of the protective cover while facilitating user operation of the mobile phone 120 located inside the protective case 100, the protective case 100 is provided with a speaker hole, a camera hole, a power button hole, volume button holes, and a charging port. When the mobile phone 120 is assembled in the receiving slot 110, the speaker hole, camera hole, power button hole, volume button holes, and charging port correspond one-to-one with the speaker, camera, power button, volume buttons, and charging port on the mobile phone 120. Optionally, the protective case 100 is also provided with a lanyard hole.

[0059] To free up the user's hands and allow the mobile phone 120 installed inside the protective case 100 to be supported on a flat surface, a positioning boss 900 is provided on the back of the protective case 100. A bracket 910 is provided on the positioning boss 900. The bracket 910 has the same shape as the positioning boss 900 and is hinged to the positioning boss 900. When the bracket 910 forms an angle with the protective case 100 via the hinge, the bracket 910 supports the mobile phone 120 located inside the protective case 100. The camera hole on the protective case 100 passes through the positioning boss 900, and the positioning boss 900 surrounds the edge of the camera hole. The bracket 910 can be hinged to the positioning boss 900 via a damping shaft. Furthermore, the positioning boss 900 is provided with a groove that accommodates the bracket 910 and has the same shape as the bracket 910. The bracket 910 is made of metal.

[0060] The working principle of this utility model is as follows: the protective cover is composed of a PC material frame 600 and a tempered glass back panel 700. The two parts are detachably combined to form a strong and durable structure. The inner wall of the frame 600 has ribs 150 and raised edges 160. These designs effectively absorb and disperse impact force when the phone 120 is accidentally dropped, reducing physical damage to sensitive internal components such as the e-ink screen and NFC antenna 400. Furthermore, the thicker wall design at the top and bottom provides additional protective buffers, further reducing the impact of vibration on internal components. The e-ink screen is mounted on the back of the protective case 100 and embedded in the mounting slot 310 on the mounting plate 300, preventing it from protruding and affecting the overall appearance and grip. The e-ink screen is connected to the built-in NFC antenna 400 via a connecting component 500. This connecting component 500 includes a ribbon cable 510, a connecting terminal 520, and a connector 530. One end of the ribbon cable 510 is electrically connected to the NFC antenna 400, and the other end is connected to the e-ink screen via the connecting terminal 520. When replacement or maintenance is required, the NFC antenna 400 can be separated from the e-ink screen via the connection component 500, and the corresponding parts can be replaced. Different antennas can be used with the same transmission mechanism for different models of protective covers, which improves assembly efficiency and reduces assembly costs.

[0061] In use, first thread the lanyard through the lanyard opening, then slip the protective case 100 onto the phone 120, ensuring that the phone 120's camera, volume buttons, power button, charging port, and speaker align with the camera, volume button, power button, charging port, and speaker holes on the protective case 100, respectively. The e-ink screen wirelessly connects to the NFC module within the phone 120 via the NFC antenna 400 to obtain power and data. Due to the characteristics of e-ink screens, the displayed content remains even after power is cut off, greatly reducing power consumption.

[0062] In summary, this drop-proof smart protective case for mobile devices, through its structural design and material application, is suitable for mobile devices such as tablets or phones, providing comprehensive protection while ensuring the stable and efficient operation of the e-ink screen, thus improving user experience and product lifespan.
