Technical Field

[0001] The present invention relates to the technical field of mobile phone cases, and particularly to a mobile phone case with an electronic ink display based on NFC.

Background Art

[0002] A mobile phone case is an accessory that protects and decorates the appearance of a mobile phone. An electronic ink display is an innovative new method and technology related to information display. On the same side as most conventional inks, the electronic ink and the lines where its color changes are printed on the surfaces of many materials such as curved plastics, polyester films, paper, and cloth. On a different side from conventional paper, the color of the electronic ink changes in an energized state, and in addition, it can display changing images like a conventional display.

[0003] Existing mobile phone cases with electronic ink displays usually need to be charged after a certain period of use by means of separate power supply, and there is no deformation during use. Due to the charging structure of the mobile phone case, the thickness and weight of the mobile phone case increase simultaneously. Even though the main purpose of the mobile phone case is to protect the mobile phone, the increase in thickness and weight makes it inconvenient to carry and use, and also affects the aesthetics.

[0007] Preferably, the mobile phone case with an NFC-based electronic ink display further comprises a mounting plate located on the back of the protective case, the upper end of the mounting plate having a mounting groove for mounting the NFC antenna and the electronic ink display, so that the edge of the NFC antenna is firmly adjacent to the edge of the protective case, thereby increasing the overlapping area due to projection between the NFC antenna and the NFC antenna of the mobile phone.

[0008] Preferably, the upper edge of the mounting groove extends to the frame at the upper end of the protective case, and the upper edge of the mounting groove is positioned higher than the inner wall at the upper end of the protective case, thereby increasing the overlapping area due to projection between the NFC antenna and the NFC antenna of the mobile phone.

[0009] Preferably, the distance between the edge of the mounting groove that approaches the side wall of the protective case and the edge of the protective case is set to less than 5 mm, thereby increasing the overlapping area due to projection between the NFC antenna and the NFC antenna of the mobile phone.

[0010] Preferably, the mobile phone case with an NFC-based electronic ink display further comprises an NFC cover plate, the NFC cover plate covering the NFC antenna. When the NFC cover plate covers the NFC antenna, the NFC cover plate is located in the same plane as the upper surface of the mounting plate.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly and easily understand the objects, features, and advantages of the present invention, we will next clearly and fully describe the technical solutions in the embodiments of the present invention in connection with the drawings in the embodiments of the present invention. It will be quite clear that the following-described embodiments are only a part of the embodiments of the present invention and not all of the embodiments. All other embodiments obtained on the premise that those skilled in the art do not perform creative labor based on the embodiments of the present invention are included in the protection scope of the present invention.

[0021] In the description of this invention, terms such as "up," "down," "top," "bottom," "inside," and "outside" represent orientations or positional relationships based on the directions or positional relationships shown in the drawings, and are used solely for the convenience of describing and simplifying the invention. They do not explicitly state or suggest that the mentioned devices or elements must be placed or positioned / operated along a particular direction, and therefore should not be interpreted as limitations on the invention. Where one part is considered to "connect" to another part, it should be clarified that the part may be directly connected to the other part or connected to the other part via an intermediate part.

[0022] We will now further explain the technical solutions of the present invention through specific embodiments, linked to Figures 1-18.

[0023] A mobile phone case 120 with an NFC-based electronic ink display 200, comprising a protective case 100 and a housing cavity 110 for placing a mobile phone 120 in the protective case 100, further comprising an NFC antenna 400 and an electronic ink display 200 located on the back of the protective case 100, A connecting assembly 500 is provided between the electronic ink display 200 and the NFC antenna 400, and the connecting assembly 500 is used to electrically connect the NFC antenna 400 to the electronic ink display 200 or to disconnect the electrical connection between the NFC antenna 400 and the electronic ink display 200. A mobile phone case with 200 NFC-based electronic ink displays, characterized by the following features.

[0024] The protective case 100 comprises a frame 600 and a rear panel 700, and the housing cavity 110 is formed by being surrounded by the frame 600 and the rear panel 700. In this embodiment, the electronic ink display 200 inside the protective case 100 does not require an external connection cable or terminal plug to operate, and data transmission is achieved by activating the main control program by means of NFC coil coupling technology when in use, and the transmitted content can be clearly displayed, eliminating the need for a built-in battery or Bluetooth connection, and the image on the protective case 100 can be switched at any time, thus realizing true wireless transmission. When the electronic ink display 200 is operating, the electronic ink display 200 wirelessly connects to the NFC antenna 400 built into the mobile phone 120 via the NFC antenna 400 inside the protective case 100, thereby enabling charging from the mobile phone 120 via the NFC antenna 400, and consequently eliminating the need to integrate the power supply inside the electronic ink display 200. The protective case 100 receives a small charge from the mobile phone 120 via NFC when transmitting a new image. After transmission is complete, the image displayed on the electronic ink display 200 does not need to be maintained by a power source, as the ink sac particles are moved to different positions under the action of positive and negative charges. When the current is cut off, the ink sac particles remain in their current positions, eliminating the need for power maintenance. This design, which reduces the power demand from the mobile phone 120 to a very small, negligible level, may reduce the weight and thickness of the protective case 100. Furthermore, the NFC antenna 400 inside the protective case 100 connects to the NFC antenna 400 built into the mobile phone 120 via wireless matching, enabling the display of data transmitted by the mobile phone 120 on the electronic ink display 200. By providing the connecting assembly 500, the NFC antenna 400 and the electronic ink display 200 on the protective case 100 are separated, making it convenient to combine different NFC antennas 400 with the electronic ink display 200 via the same connecting assembly 500, and ensuring compatibility of the mobile phone 120 case with the NFC electronic ink display 200 for different models of the mobile phone 120.

[0025] Preferably, to electrically connect the NFC antenna 400 to the electronic ink display 200, or to disconnect the electrical connection between the NFC antenna 400 and the electronic ink display 200, the connection assembly 500 comprises a flat cable 510, a connection terminal 520, and a connection element 530. One end of the flat cable 510 is electrically connected to the NFC antenna 400, and a through hole 540 is provided in the flat cable 510. The connection terminal 520 is located at the other end of the flat cable 510 away from the NFC antenna 400, and the connection element 530 is located on the back of the protective case 100 and electrically connects to the electronic ink display 200. The connection element 530 can be plugged into or separated from the connection terminal 520 to achieve an electrical connection between the NFC antenna 400 and the electronic ink display 200, or an electrical disconnection between the NFC antenna 400 and the electronic ink display 200. In one embodiment, the electronic ink display 200 comprises the electronic ink display 200 and a control circuit board 640 electrically connected to the electronic ink display 200, and the connecting element 530 is attached to the control circuit board 640 by means of adhesive or welding and electrically connected to the control circuit board 640.

[0026] In one embodiment, the frame 600 and the rear panel 700 are molded as a single unit, and the frame 600 is made of TPU+TPE material and is rectangular in shape. This is because, when the mobile phone 120 is dropped, the TPE effectively absorbs and disperses the impact force, mitigating the impact force received by each component of the mobile phone 120, especially the fragile display and its internal elements. Compared to other rigid materials, the flexibility of TPE minimizes the risk of damage when the mobile phone 120 is dropped, thus playing a protective role. TPU not only has good collision prevention performance but also excellent tactile feel and anti-slip properties. When used as the manufacturing material for the frame 600 of the protective case 100, it not only improves the comfort of holding the mobile phone 120 but also effectively reduces the probability of the mobile phone 120 slipping from the hand. Furthermore, TPU and TPE materials are suitable for weight reduction compared to metal or other rigid materials, and by adopting these materials for the frame 600, the weight of the protective case 100 does not increase significantly. This helps maintain the lightweight design of the mobile phone case 120, meeting the user's demand for lightweight portable devices. The rear panel 700 is made of tempered glass, and the tempered glass used as the material for the rear panel 700 has extremely high transparency and excellent abrasion resistance, which can provide a clear visual effect. Moreover, due to its high hardness, the tempered glass is effectively resistant to scratches and wear from daily use, protecting the electronic ink display 200 from damage. In addition, a camera section is provided which is molded integrally with the upper end of the frame 600, and the camera section extends away from the mounting plate 300 from the frame 600.

[0027] In another embodiment, in terms of external design, the rear panel 700 of the electronic ink display 200 and the frame 600 of the mobile phone 120 are arranged separately, the frame 600 is detachably connected to the rear panel 700, and the housing cavity 110 is formed enclosed by the frame 600 and the rear panel 700. Position-restricting edges 610 are provided on the side walls of the frame 600, and the position-restricting edges 610, together with the inner wall of the frame 600, form a clamping groove, and the edge of the rear panel 700 is retained in this clamping groove. With the design of this embodiment, the user can not only freely change the design on the electronic ink display 200, but also switch the edge frame of the protective case 100 according to personal preference. The frame 600 is made of PC material, and the rear panel 700 is made of tempered glass material. PC material is a more durable material with high impact resistance, which can better protect your valuable mobile phone during daily use. It does not fade even after long-term use, has a delicate feel, and has rounded corners to improve protection. The tempered glass used as the material for the rear panel 700 has extremely high transparency and excellent abrasion resistance, which can provide a clear visual effect. In addition, due to its high hardness, the tempered glass can effectively withstand scratches and abrasion from daily use, protecting the electronic ink display 200 from damage. The two components, the PC material frame 600 and the tempered glass rear panel 700, are assembled in a detachable manner to form a structure with excellent strength and durability.

[0028] Accordingly, the mobile phone 120 case with an NFC electronic ink display 200 further comprises a mounting plate 300 located on the back of the protective case 100, and a mounting groove 310 for mounting the NFC antenna 400 and the electronic ink display 200 is provided at the top of the mounting plate 300. The edges of the NFC antenna 400 are firmly adjacent to the edges of the protective case 100, thereby increasing the overlapping area due to projection between the NFC antenna 400 and the NFC antenna 400 of the mobile phone 120, and maximizing the usable installation area of ​​the NFC antenna 400. If the area of ​​the protective case 100 does not increase, the rear panel 700 of the protective case 100 allows for the accommodation of an NFC antenna 400 with a larger area, thereby improving the NFC signal transmission performance of the device.

[0029] In one embodiment based on the above embodiment, the upper edge of the mounting groove 310 extends to the frame at the upper end of the protective case 100, and the upper edge of the mounting groove 310 is positioned higher than the inner wall at the upper end of the protective case 100, thereby increasing the overlapping area due to projection between the NFC antenna 400 and the NFC antenna 400 of the mobile phone 120.

[0030] At least one of the cross-sectional areas at the top and bottom ends of the protective case 100 is larger than the cross-sectional area at the left and right sides of the protective case 100.

[0031] When the mobile phone 120 is placed in the housing cavity 110, the plane of the mobile phone 120 forms a first buffer portion 130 and a second buffer portion 140 with the upper and lower end walls and the left and right side walls, respectively, and the distance between the first buffer portion 130 and the plane of the mobile phone 120 is greater than the distance between the second buffer portion 140 and the plane of the mobile phone 120. The reason for designing the upper and lower ends of the protective case 100 to have greater thickness than the left and right ends is, on the one hand, that as the area of ​​the NFC antenna 400 increases, the installation space inside the protective case 100 needs to be increased accordingly. Increasing the thickness of the upper and lower ends of the protective case 100 achieves this increase in installation space, thereby not only providing sufficient space for the mounting groove 310 for the large NFC antenna 400, but also maintaining the overall size and portability of the protective case 100. The thickened upper and lower end walls not only provide the space necessary for installing the large NFC antenna 400, but also improve signal strength and enhance device compatibility, resulting in a stronger signal transmission capability and the ability to interact with NFC devices of various sizes and shapes. On the other hand, this design increases the structural strength of the protective case 100, providing better protection against drops and impacts.

[0032] In the design of this embodiment, the need to protect sensitive elements within the mobile phone 120, particularly the NFC antenna 400 and the electronic ink display 200, is taken into consideration. As the NFC antenna 400 is a critical part of communication, its area increases, making it more susceptible to impact damage when dropped. To mitigate this impact, increasing the thickness of the upper and lower edges of the protective case 100 not only provides stronger physical protection when the mobile phone 120 is dropped, but also gains a larger buffer area through the thickened edge walls, effectively absorbing impact and reducing damage to the NFC antenna 400 due to vibration. Alternatively, since the electronic ink display 200 is relatively fragile and easily damaged by physical impact as a display technology, the design of the protective case 100 also helps protect the electronic ink display 200. Such a design reduces the failure rate caused by drops or impacts during daily use and extends the service life of the equipment. Furthermore, the structure of the protective case 100 also supports the functional enhancement of the NFC antenna 400, allowing for an increase in antenna area without increasing the risk of damage.

[0033] In another embodiment based on the above embodiment, the distance between the edge of the mounting groove 310 that approaches the side wall of the protective case 100 and the edge of the protective case 100 is set to less than 5 mm, thereby increasing the overlapping area due to projection between the NFC antenna 400 and the NFC antenna 400 of the mobile phone 120.

[0034] This embodiment of design maximizes the usable footprint of the NFC antenna 400, allowing it to gain a larger footprint within the existing design framework of the protective case 100 without increasing the area of ​​the protective case 100. This not only saves space but also maintains the lightweight characteristics of the protective case 100.

[0035] Preferably, the mobile phone case 120 with an electronic ink display 200 further comprises an NFC cover plate 410, the NFC cover plate 410 covering the NFC antenna 400. When the NFC cover plate 410 covers the NFC antenna 400, the NFC cover plate 410 is positioned on the same plane as the upper surface of the mounting plate 300.

[0036] In this embodiment, an NFC cover plate 410 is added to the NFC antenna 400, the NFC cover plate 410 is designed to match the shape of the NFC antenna 400, and when the NFC cover plate 410 covers the NFC antenna 400, the NFC cover plate 410 is positioned on the same plane as the upper surface of the mounting plate 300. When the NFC cover plate 410 is attached and covers the NFC antenna 400 without any gaps, the design of the NFC cover plate 410 allows the NFC antenna 400 to be securely mounted in the groove, preventing the NFC antenna 400 from becoming loose or shifting during use. Furthermore, the buffering protective layer formed by this design effectively absorbs and disperses external pressure, preventing damage to the NFC antenna 400.

[0037] In one embodiment, the corners of the protective case 100 are provided with projections to prevent bursting.

[0038] Providing rupture-preventing protrusions at the four corners of the frame 600 helps to disperse and absorb impact forces from all angles. If the mobile phone 120 is accidentally dropped from a high position, the rupture-preventing protrusions will effectively transfer and disperse the impact force, reducing the impact force acting directly on the surface and internal components of the mobile phone 120. This design helps protect sensitive elements inside the mobile phone 120 and the protective case 100, such as the chip inside the mobile phone 120, the electronic ink display 200, and the NFC antenna 400, reducing the possibility of damage.

[0039] Furthermore, in this embodiment, ribs 150 are further arranged on the inner wall of the protective case 100, and this design reduces the damage that occurs to the mobile phone 120 when it is dropped. The protective case 100 comprises a frame 600 and a rear panel 700, and two ribs 150 are arranged on the inner wall of the upper and lower ends of the frame 600. This design helps to increase the overall strength of the protective case 100. With this setup, when the mobile phone 120 is subjected to impact, the impact force can be absorbed and dispersed, reducing damage to the internal components of the mobile phone 120.

[0040] In one embodiment, a cushioning material 320 is provided in the mounting groove 310.

[0041] To reduce the stress on the electronic ink display unit 200 caused by the fall of the protective case 100, a cushioning material 320 is placed between the rear panel 700 and the electronic ink display unit 200 within the mounting groove 310. The cushioning material 320 is foamed cotton, which may be highly elastic PORON foamed cotton. The front and back surfaces of the foamed cotton may be attached to the bottom surface of the mounting groove 310 and the electronic ink display unit 200, respectively, using adhesive.

[0042] In one embodiment, cushioning protrusions are provided on the edges of the protective case 100.

[0043] If multiple cushioning protrusions are also placed on the edges of the protective case 100, the placement of these protrusions may form an additional protective layer on the edges of the mobile phone 120. On the one hand, if the mobile phone 120 is accidentally dropped, the cushioning protrusions will make contact with the ground first, dispersing the impact force and reducing the force directly transmitted to the edges of the mobile phone 120, thereby lowering the risk of damage to the mobile phone 120. In addition, the cushioning protrusions will increase the structural strength of the edges of the protective case 100, making it more resistant to impact during drops and reducing cracks and damage caused by drops. On the other hand, the cushioning protrusions will increase friction between the hand and the protective case 100, providing a better grip, allowing the user to feel more stable when holding the mobile phone 120 and reducing the probability of dropping the mobile phone 120. Because the cushioning protrusions increase friction, the probability of dropping the mobile phone 120 is also reduced even when the hands are wet or sweaty, improving the safety of using the mobile phone 120. The cushioning protrusions may be made of materials such as silicone or rubber.

[0044] A lens frame 900 is attached to the back of the protective case 100, and the lens frame 900 is hinged to a holder 910. When the protective case 100 is placed horizontally, the holder 910 expands to support the mobile phone case 120.

[0045] In this embodiment, the mobile phone 120 case with an electronic ink display 200 has a camera section molded integrally with the upper end of the frame 600. The camera section extends away from the mounting plate 300 from the frame 600, and a ridge is provided on the back of the protective case 100 as it approaches the edge. This ridge surrounds the lens frame 900 and approaches both sides of the edge, thereby protecting the camera. To free the user's hands, the mobile phone 120 placed inside the protective case 100 is supported on a flat surface. A lens frame 900 is provided on the back of the protective case 100, and a holder 910 is provided on the lens frame 900. The shape of the holder 910 is the same as the shape of the lens frame 900, and the lens frame 900 is connected to the holder 910 by a hinge. When the holder 910 forms an angle with the protective case 100 via the hinge, the holder 910 supports the mobile phone 120 located inside the protective case 100. Preferably, the holder 910 is hinged onto the lens frame 900 via a damping shaft. Furthermore, the lens frame 900 is provided with a groove that accommodates the holder 910 and conforms to its shape, and the holder 910 is made of metal.

[0046] Furthermore, in this embodiment, in order to realize the basic functions of the mobile phone case 120 and to make it convenient to operate the mobile phone 120 inside the protective case 100, a loudspeaker hole 670, a camera hole 710, an ON / OFF hole, a volume control key hole 650, and a charging hole 680 are provided on the protective case 100. When the mobile phone 120 is assembled into the housing cavity 110, the loudspeaker hole 670, camera hole 710, ON / OFF hole, volume control key 650, and charging hole 680 correspond to the loudspeaker, camera, ON / OFF key, volume control key, and charging port of the mobile phone 120, respectively. Preferably, a lanyard hole 660 is also provided on the protective case 100.

[0047] Preferably, to facilitate the fitting of the NFC antenna 400 into the housing cavity 110, the bottom surface of the housing cavity 110 of the protective case 100 is covered with a Mylar film 630, and the NFC antenna 400 is positioned between the Mylar film 630 and the rear panel 700. The Mylar film 630 may be a PC Mylar film 630.

[0048] The operating principle of the present invention is roughly as follows: When in use, first the lanyard is passed through the lanyard hole, then the mobile phone 120 is placed in the protective case 100, and the loudspeaker hole 670, camera hole 710, ON / OFF hole, volume control key hole 650 and charging hole 680 of the mobile phone 120 are secured so that they correspond one-to-one with the loudspeaker, camera, ON / OFF key, volume control key and charging port of the mobile phone 120, respectively. After correct installation, the NFC antenna 400 on the protective case 100 corresponds to the NFC antenna 400 specific to the mobile phone 120, the electronic ink display 200 on the protective case 100 is charged from the mobile phone 120 via the NFC antenna 400 and the NFC antenna 400 specific to the mobile phone 120, and the electronic ink display 200 is connected to the NFC antenna 400 via the connecting assembly 500, thereby achieving image conversion on the electronic ink display 200. Before the next charge, the electronic ink display 200 may continue to display an image. When product replacement or repair is required, the NFC antenna 400 can be removed from the electronic ink display 200 via the connecting assembly 500, the corresponding parts can be replaced, and then the different antenna can be applied to different models of mobile phone cases in the same transmission mechanism, thereby improving assembly efficiency and reducing assembly costs.
