Description

Technical Field

[0001] This utility model relates to the field of protective case technology, and in particular to a protective case for a portable mobile terminal. Background Technology

[0002] With the widespread use of electronic devices, users' functional demands for protective cases are constantly increasing. In recent years, mobile terminal protective cases with auxiliary displays (such as e-ink screens, secondary screens, etc.) have become increasingly popular. These products can display information such as time, notifications, and weather without turning on the main screen, saving power and improving convenience. However, existing mobile terminal protective cases with displays usually adopt a fixed structure, which prevents users from freely replacing the cover, limiting the personalized choices of the products.

[0003] Currently, existing technologies use magnetic structures to achieve detachable cover designs, such as embedding circular magnets in corresponding positions on the phone case and the cover, using magnetic force to fix the cover. However, this solution has significant drawbacks for phone cases with displays: because the display occupies the central area of ​​the protective case, it is impossible to place a circular magnet in the center, resulting in the cover not being securely fixed or the magnetic force being unevenly distributed, affecting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a protective case for a portable mobile terminal, in which the magnetic attachment is located around the e-ink screen rather than on the back. This allows the magnetic attachment on the case to be positioned closer to the magnetic attachment on the cover, thereby strengthening the magnetic force. This not only enables easy removal of the cover but also provides more secure magnetic attachment without obstructing the e-ink screen.

[0032] With the widespread use of electronic devices, users' functional demands for protective cases are constantly increasing. In recent years, mobile terminal protective cases with auxiliary displays (such as e-ink screens, secondary screens, etc.) have become increasingly popular. These products can display information such as time, notifications, and weather without turning on the main screen, saving power and improving convenience. However, existing mobile terminal protective cases with displays usually adopt a fixed structure, preventing users from freely replacing the cover and limiting personalized choices. Currently, existing technology uses a magnetic structure to achieve a detachable cover design, such as embedding circular magnets in corresponding positions on the phone case and the cover, using magnetic force to fix the cover. However, this solution has a significant drawback for phone cases with displays: because the display occupies the central area of ​​the protective case, it is impossible to place a circular magnet in the center, resulting in an unstable cover or uneven distribution of magnetic force, affecting the user experience.

[0033] See Figures 1-6To address the aforementioned issues, this application provides a protective case 10 for a portable mobile terminal, comprising a housing 20, a display component 30, a cover plate 40, and a magnetic clasp. The housing 20 has an inner side 21 facing the mobile terminal and an outer side 22 facing away from it. The housing 20 forms a mounting cavity 201 on one side of the inner side 21 to mount the portable mobile terminal. The display component 30 includes a communication module 31 and an e-ink screen 32 disposed on the housing 20. The communication module 31 and the e-ink screen 32 are electrically connected, and the display surface 33 of the e-ink screen 32 faces the outer side 22. The cover plate 40 is mounted on the housing 20 and located on the side of the e-ink screen 32 away from the mounting cavity 201. The magnetic clasp is fixed to the housing 20 and the cover plate 40, and the magnetic clasp is located on the periphery of the e-ink screen 32. The magnetic clasp on the housing 20 and the cover plate 40 magnetically engage with each other to fix the cover plate 40 to the housing 20.

[0034] See Figures 1-6 , Figure 1 A schematic diagram of the structure of the protective case 10 for a portable mobile terminal provided in one embodiment of this application; Figure 2 A schematic diagram of a portion of the structure of the protective case 10 for a portable mobile terminal provided in an embodiment of this application; Figure 3 A schematic diagram of a portion of the structure of the protective case 10 for a portable mobile terminal provided in an embodiment of this application; Figure 4 A schematic diagram of a portion of the structure of the protective case 10 for a portable mobile terminal provided in an embodiment of this application; Figure 5 A schematic diagram of a portion of the structure of the protective case 10 for a portable mobile terminal provided in an embodiment of this application; Figure 6 This is an exploded view of a protective case 10 for a portable mobile terminal provided in one embodiment of this application. The protective case 10 integrates an e-ink screen 32 and a magnetically replaceable cover 40, suitable for various usage scenarios and meeting the needs of different user groups. For example, it can be used in business office scenarios, where the e-ink screen 32 can always display information such as schedules, emails, and meeting reminders, allowing business people to obtain key notifications without frequently unlocking their phones, thus improving work efficiency. The replaceable leather or metal-style cover 40 makes the phone case more suitable for business occasions. It can also be used for everyday life; the e-ink screen 32 can be used to display photos, and users can change the photos displayed on the e-ink screen 32 through the portable mobile terminal, increasing the aesthetics and richness of the portable mobile terminal.

[0035] The protective case 10 for a portable mobile terminal includes a housing 20, a display component 30, a cover plate 40, and a magnetic connector. The housing 20 has an inner side 21 facing the mobile terminal and an outer side 22 opposite to it. A mounting cavity 201 is formed on one side of the inner side 21 of the housing 20, allowing the portable mobile terminal to be placed inside the mounting cavity 201 to mount the protective case onto the portable mobile terminal. The display component 30 includes a communication module 31 and an e-ink screen 32 disposed on the housing 20. The communication module 31 is responsible for data interaction with the portable mobile terminal, such as receiving notifications, time, weather, and other information pushed by the mobile phone, and transmitting them to the e-ink screen 32 for display. Specifically, the communication module 31 is electrically connected to the e-ink screen 32. The display surface 33 of the e-ink screen 32 faces the outer side 22. The e-ink screen 32 can display photos, and users can change the photos or patterns displayed on the e-ink screen 32 according to their preferences, thereby improving the aesthetics and richness of the protective case 10 for the portable mobile terminal. The cover plate 40 is mounted on the housing 20 and located on the side of the e-ink screen 32 away from the mounting cavity 201. Covering the e-ink screen 32, the cover plate 40 protects it from scratches or impacts. The cover plate 40 can be made of a high-transmittance material to ensure the content displayed on the e-ink screen 32 is clearly visible. To facilitate easy installation and removal of the cover plate 40, the protective housing 10 of the portable mobile terminal provided by this invention is equipped with a magnetic chuck. Specifically, the magnetic chuck is fixed to the housing 20 and the cover plate 40, and is located on the periphery of the e-ink screen 32 to avoid affecting the normal display. The magnetic chuck is located on the periphery of the e-ink screen 32, rather than on the back, allowing the magnetic chuck on the housing 20 to be closer to the magnetic chuck on the cover plate 40, strengthening the magnetic force. This provides both easy removal of the cover plate 40 and sufficient magnetic stability, without obstructing the e-ink screen 32. When the cover plate 40 approaches the housing 20, the magnetic attachments on the housing 20 and the cover plate 40 attract each other, firmly fixing the cover plate 40 to the housing 20. The cover plate 40 is removable, allowing users to easily replace it with different colors or styles according to their personal preferences, increasing the versatility of the protective case. Compared to the traditional center magnetic attachment solution, this edge magnetic attachment design ensures the sturdiness of the cover plate 40 without interfering with the layout of the display screen, improving the product's practicality and user experience.

[0036] See Figures 1-6The housing 20 includes a detachably connected first housing 23 and second housing 24. The first housing 23 and the second housing 24 can be fixedly connected by adhesive or snap-fit. Specifically, in one embodiment, the first housing 23 and the second housing 24 are fixedly connected by adhesive; in another embodiment, they are fixedly connected by snap-fit. The first housing 23 and the second housing 24 can also be fixedly connected by adhesive and snap-fit. The communication module 31 and the e-ink screen 32 are disposed on the first housing 23, and a mounting cavity 201 is formed on the second housing 24. The size and shape of the mounting cavity 201 can be designed according to the size of the portable mobile terminal. The first housing 23 is mounted on the second housing 24. In some embodiments, the first housing 23 has a first receiving slot and a second receiving slot. The e-ink screen 32 is mounted in the first receiving slot, and the communication module 31 is mounted in the second receiving slot. By installing the e-ink screen 32 and the communication module 31 in separate areas, the physical isolation between the communication module 31 and the e-ink screen 32 can be achieved, effectively avoiding electromagnetic interference. In one embodiment, during assembly, the first housing 23, which integrates the e-ink screen 32, is gently pressed against the interface of the second housing 24 until a "click" sound indicates that it is properly installed. The user places the portable mobile terminal into the mounting cavity 201 of the second housing 24 to install the protective case. Finally, the optional cover plate 40 is placed near the edge of the housing 20, and the strong magnetic force automatically guides the cover plate 40 to be precisely positioned and firmly attached. The entire process requires no tools and is simple and quick.

[0037] See Figure 2 and Figure 3The magnetic components include a first magnetic component 51 and a second magnetic component 52. In some embodiments, the first magnetic component 51 is fixed only to the first housing 23, and in other embodiments, the first magnetic component 51 is fixed only to the second housing 24. The first magnetic component 51 can also be fixed to both the first housing 23 and the second housing 24 simultaneously. The second magnetic component 52 is fixed to the cover plate 40, which is mounted on the second housing 24. Specifically, the second housing 24 and the cover plate 40 are fixedly connected by at least one of adhesive and snap-fit ​​methods to ensure a stable connection between them. The protective case 10 of this portable mobile terminal enables the cover plate 40 to be replaceable. The edge magnetic design of the first magnetic component 51 and the second magnetic component 52 ensures that the cover plate 40 is firmly fixed while avoiding interference with the e-ink screen 32 caused by the traditional center magnetic attraction method. In some embodiments, the first magnetic element 51 and the second magnetic element 52 can be made of rare earth materials, providing strong and stable magnetic force to ensure that the cover 40 will not accidentally fall off during normal use, while allowing users to easily disassemble and replace it. Multiple first magnetic elements 51 and multiple second magnetic elements 52 can be provided. Preferably, the first magnetic elements 51 and the second magnetic elements 52 correspond one-to-one in the mounting direction of the cover 40 and the second housing 24 to increase the stability of the magnetic attraction.

[0038] The first housing 23 is located at the bottom of the mounting cavity 201, with the display surface 33 of the e-ink screen 32 facing the bottom of the mounting cavity 201. This effectively protects the e-ink screen 32 from direct external impacts, greatly improving the product's durability. Secondly, by placing the e-ink screen 32 on the inside, light reflection can be better controlled, ensuring a clear display effect under various lighting conditions. The bottom of the mounting cavity 201 has a light-transmitting area directly opposite the display surface 33 of the e-ink screen 32, exposing the display surface 33. Preferably, the light-transmitting area can be made of optical-grade light-transmitting material, providing good light transmittance and scratch resistance, thus making the display of the e-ink screen 32 clearer. Simultaneously, the material of the light-transmitting area can have anti-glare properties, ensuring good visibility even in strong light environments.

[0039] In some embodiments, the shape of the light-transmitting area can be varied to display different shapes of the e-ink screen 32. A light-transmitting portion is formed on the cover plate 40, facing the display surface 33 of the e-ink screen 32, exposing the display surface 33 of the e-ink screen 32 to form a complete display channel. The light-transmitting portion can be treated with a nano-level coating process, ensuring high light transmittance while effectively reducing fingerprint residue and maintaining long-term cleanliness. When the user places the portable mobile terminal into the protective case, the content of the e-ink screen 32 can be clearly displayed through the bottom light-transmitting area and the light-transmitting portion of the cover plate 40. While protecting the portable mobile terminal, the user can view the information on the e-ink screen 32 at any time without additional operation. The double-layer light-transmitting structure design protects the display screen while ensuring optimal visual effects. In some embodiments, the cover plate 40 is provided with a non-transparent part. In the mounting direction of the cover plate 40 and the second housing 24, the non-transparent part faces the communication module 31. The non-transparent part can block the communication module 31 on the outer side 22 of the protective shell 10 of the portable mobile terminal, hide the communication module 31 on the outer side 22 of the protective shell, and thus improve the aesthetics of the protective shell 10 of the portable mobile terminal.

[0040] In some embodiments, the second housing 24 also forms a snap-fit ​​cavity 241 on the side opposite to the mounting cavity 201. The cover plate 40 is installed in the snap-fit ​​cavity 241, and the size and shape of the snap-fit ​​cavity 241 are adapted to the cover plate 40. When the cover plate 40 is installed, the inner wall of the snap-fit ​​cavity 241 can automatically guide and position itself, ensuring accurate installation each time. In some embodiments, the first housing 23 is fixed to the bottom of the snap-fit ​​cavity 241, and the display surface 33 of the e-ink screen 32 faces the side opposite to the bottom of the snap-fit ​​cavity 241. The cover plate 40 has a light-transmitting part facing the display surface 33 of the e-ink screen 32 to expose the display surface 33 of the e-ink screen 32. The edge of the snap-fit ​​cavity 241 can be designed with a slight arc to ensure both smooth installation of the cover plate 40 and a tight fit after installation. The design of the snap-fit ​​cavity 241 makes the installation of the cover plate 40 more stable and reliable, and it will not loosen or fall off even during vigorous movement. At the same time, the embedded structure effectively reduces the overall thickness of the protective shell, maintaining the thin and light characteristics of the protective shell.

[0041] See Figure 2 and Figure 3The first housing 23 and the second housing 24 are each provided with a first magnetic 51 on both the left and right sides of the e-ink screen 32, and the cover plate 40 is provided with a second magnetic 52 on both the left and right sides of the light-transmitting part. This bilateral magnetic attraction securely fixes the cover plate 40 to the left and right sides of the e-ink screen 32, achieving a stable connection between the cover plate 40 and the housing 20. The first magnetic 51 on the first housing 23 and the second housing 24 is symmetrically arranged on the left and right sides of the e-ink screen 32. This bilateral layout ensures balanced force distribution, making the entire protective shell structure more stable and reliable. In some embodiments, the second magnetic 52 on the cover plate 40 is kept at an appropriate distance from the light-transmitting part, which neither affects the display effect nor fails to provide sufficient attraction force.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
