Description

Technical Field

[0001] The utility model relates to the technical field of mobile device protection shells, in particular to a protection cover for mobile devices. Background Art

[0002] With the rapid development of modern communication technology, smartphones have become an indispensable tool in people's daily lives. In order to effectively protect smartphones from physical damage during daily use and meet users' demand for personalized appearance, various forms of mobile phone protective cases have appeared on the market. Mobile phone protective cases not only provide physical protection for the device, but also enhance the aesthetics and functionality of the phone.

[0003] In recent years, with the continuous innovation of display technology, electronic ink screen technology has gradually been applied to peripheral accessories of various mobile devices. Electronic ink screens utilize electronic ink display technology to enable display content to be "printed" on a variety of surfaces like traditional ink, including curved plastic, polyester film, paper and even cloth. Unlike traditional paper media, electronic ink screens can change color after power is turned on and support the display of dynamic images. Therefore, they are widely used in low-power, high-contrast display scenarios, such as e-books, smart watches and other devices.

[0004] Although electronic ink screen technology is very mature, when applying this technology in smartphone protective cases, it still faces problems such as battery life and high-quality display effects. In order to improve the display quality of the electronic ink screen and extend the battery life of the device, the solution in the existing technology is to increase the area of the NFC energy receiving antenna to enhance the device's signal reception capability and data transmission efficiency. However, in order to accommodate a larger NFC energy receiving antenna in the limited space of the mobile phone case, the usual practice is to increase the thickness or volume of the back panel of the protective case, or to open a mounting slot on the back panel that extends obliquely upward along the upper end of the protective case. However, although this design can achieve the purpose of increasing the antenna area, this design method increases the overall thickness and weight of the protective case, and reduces the grip feel of the device, which does not meet consumers' expectations for a lightweight, portable, and comfortable smart device protective case.

[0005] Therefore, a protective cover for a mobile device is proposed to solve the above problems. Utility Model Content

[0006] The main purpose of the present invention is to provide a protective cover for a mobile device, aiming to solve the problem that the existing mobile device protective shell cannot increase the antenna installation area without changing the shell size.

The distance between the top edge of the groove body and the edge of the protective shell is less than 5 mm to increase the projected overlapping area between the NFC energy receiving antenna and the NFC energy receiving antenna of the mobile phone.

[0010] Furthermore, it also includes an NFC cover, which is covered on the NFC energy receiving antenna. When the NFC cover is covered on the NFC energy receiving antenna, the NFC cover is flush with the upper surface of the mounting plate.

[0011] Furthermore, a connecting component is provided in the slot body, and both ends of the connecting component are respectively connected to the NFC energy receiving antenna and the display device. The connecting component is used to electrically connect the NFC energy receiving antenna to the display device or to separate the NFC energy receiving antenna from the display device.

[0039] Reference Figures 1 to 5 The utility model discloses a protective cover for a mobile device, comprising a protective shell 100, wherein the protective shell 100 is provided with a receiving slot 110 for placing a mobile phone 120, and is characterized in that it also includes a mounting plate 300, an NFC energy receiving antenna 400 and a display device 200;

[0040] A slot 310 for mounting the NFC energy receiving antenna 400 and the display device is provided on the top of the mounting plate 300. The NFC energy receiving antenna 400 and the display device 200 are electrically connected.

[0041] The NFC energy receiving antenna 400 is used to receive wireless signals and energy. The distance between the top edge of the groove body 310 and the edge of the protective shell 100 is less than 5 mm to increase the projected overlapping area between the NFC energy receiving antenna 400 and the NFC energy receiving antenna of the mobile phone.

[0042] This embodiment includes a protective case 100, a mounting plate 300, an NFC energy receiving antenna 400 and a display device 200. The protective case 100 is provided with a receiving groove 110 for placing a mobile phone 120. The mounting plate 300 is respectively provided with a groove body 310 for installing the display device 200 and the NFC energy receiving antenna 400. The NFC energy receiving antenna 400 is used to receive wireless signals and energy. The top edge of the groove body 310 is less than 5 mm away from the edge of the protective case 100 to increase the projected overlapping area of the NFC energy receiving antenna 400 and the NFC energy receiving antenna of the mobile phone, thereby maximizing the available installation area of the NFC energy receiving antenna 400. Through such a design, the back plate 700 of the protective case 100 can accommodate the installation of an NFC energy receiving antenna 400 with a larger area without increasing the area of the protective case 100, thereby improving the NFC signal transmission performance of the device.

[0043] In the prior art, increasing the area of the NFC energy receiving antenna 400 mainly relies on two methods: one is to increase the volume of the back plate 700 of the protective case 100, and the other is to open a curved groove on the back plate 700 along the upper end of the protective case 100 to increase the installation space in a manner of extending obliquely upward along the upper end of the protective case 100. However, in this method, increasing the volume of the back plate 700 will directly cause the protective case 100 to become bulky, which does not meet the requirements of lightweight mobile devices; and the curved groove body 310 design may increase the production difficulty, and the space utilization rate of the antenna layout is not high; the design of the groove body 310 in the present application enables the NFC energy receiving antenna 400 to obtain a larger installation area within the existing design framework of the protective case 100 without increasing the volume of the protective case 100, which not only saves space but also maintains the lightweight characteristics of the protective case 100.

[0044] The protective cover for the mobile device further includes an NFC cover 410 , which is disposed on the NFC energy receiving antenna 400 . When the NFC cover 410 is disposed on the NFC energy receiving antenna 400 , the NFC cover 410 is flush with the upper surface of the mounting plate 300 .

[0045] In this embodiment, an NFC cover 410 is additionally designed for the NFC energy receiving antenna 400. The NFC cover 410 is designed to be consistent in shape with the NFC energy receiving antenna 400. When the NFC cover 410 is covered on the NFC energy receiving antenna 400, the NFC cover 410 is flush with the upper surface of the mounting plate 300. The NFC cover 410 is fitted on the NFC energy receiving antenna 400 without any gap. The design of the NFC cover 410 enables the NFC energy receiving antenna 400 to be firmly installed in the slot 310, avoiding the problem of loosening or displacement of the NFC energy receiving antenna 400 during use. In addition, a buffer protective layer is formed by such a design, which can effectively absorb and disperse external pressure to avoid damage to the NFC energy receiving antenna 400.

[0046] A connecting component 500 is further provided in the slot 310 , and the two ends of the connecting component 500 are respectively connected to the NFC energy receiving antenna 400 and the display device 200 . The connecting component 500 is used to electrically connect the NFC energy receiving antenna 400 to the display device 200 or to separate the NFC energy receiving antenna 400 from the display device 200 .

[0047] The connection assembly 500 includes: a cable 510, a connection terminal 520, and a connector 530. One end of the cable 510 is electrically connected to the NFC energy receiving antenna 400, and the other end of the cable 510 is connected to the connection terminal 520. The connection terminal 520 is located at the end of the cable 510 away from the NFC energy receiving antenna 400. One end of the connector 530 is electrically connected to the display device 200, and the other end of the connector 530 can be plugged into or detached from the connection terminal 520.

[0048] The display device 200 is disposed on the back of the protective case 100. The configuration of the display device 200 enables the back of the protective case 100 to display text or images. In one embodiment, the operation of the display device 200 in the protective cover does not require any external connecting cables or terminal plugs. During use, the NFC coil coupling technology drives the main control program to achieve data transmission and clearly display the transmitted content. No internal battery or Bluetooth connection is required. The image on the protective cover can be changed at any time, realizing true wireless transmission. When the e-ink screen is in operation, the e-ink screen wirelessly connects to the NFC energy receiving antenna 400 built into the mobile phone 120 via the NFC energy receiving antenna 400 inside the protective case 100. The e-ink screen draws power from the mobile phone 120 via the NFC energy receiving antenna 400, eliminating the need for an internal power supply integrated into the e-ink screen. The protective cover only draws a small amount of power from the mobile phone 120 via NFC when transmitting a new image. After the transmission is completed, the e-ink screen display pattern does not require power to maintain. 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 position and do not move. Therefore, the image display does not require power to maintain, and the power demand on the mobile phone 120 is very small and can be ignored.

[0049] The setting of the connecting component 500 can realize the separation of the NFC energy receiving antenna 400 and the ink screen on the protective shell 100, so that different NFC energy receiving antennas 400 can be combined with the ink screen through the same connecting component 500, so that the NFC ink screen protective cover can be compatible with different models of mobile phones 120.

[0050] Specifically, in order to prevent the ink screen, the connecting terminal 520 and the connector 530 from protruding outward from the back of the protective shell 100, the ink screen, the connecting terminal 520 and the connector 530 are all installed in the groove body 310. In order to realize the separation or combination of the NFC energy receiving antenna 400 and the display device 200 to electrically connect the NFC energy receiving antenna 400 and the display device 200, the connecting component 500 includes a cable 510, a connecting terminal 520 and a connector 530. One end of the cable 510 is electrically connected to the NFC energy receiving antenna 400, and the connecting terminal 520 is arranged on the cable 510 away from the NFC energy receiving antenna 400. At one end of the receiving antenna 400, the connector 530 is arranged on the back of the protective shell 100 and is electrically connected to the display device 200. The connector 530 can be plugged into or separated from the connection terminal 520 to realize the electrical connection between the NFC energy receiving antenna 400 and the display device 200 or the electrical connection between the NFC energy receiving antenna 400 and the display device 200 is disconnected. In one embodiment, the display device 200 includes an electronic display device 200 and a control circuit board 800 electrically connected to the electronic display device 200. The connector 530 is patched or welded on the control circuit board 800 and is electrically connected to the control circuit board 800.

[0051] The protective case 100 includes a frame 600 and a back panel 700. The frame 600 and the back panel 700 are detachably connected, and the receiving slot 110 is formed by the frame 600 and the back panel 700. In terms of shell design, the e-ink screen back panel 700 and the mobile phone 120 frame 600 adopt a separate design. Users can not only change the pattern on the e-ink screen at will, but also change the frame of the protective cover according to their personal preferences.

[0052] Specifically, the frame 600 is made of TPU+TPE material, and the back panel 700 is made of tempered glass material. When the phone falls, TPE can effectively absorb and disperse the impact force, reducing the impact on various parts of the phone, especially the fragile screen and internal components. Compared with other rigid materials, the flexibility of TPE enables it to minimize the risk of damage when the phone falls, playing a protective role; TPU material not only has good anti-collision performance, but also has excellent feel and anti-slip performance. The design material of the frame used as a protective case not only enhances the grip of the phone, but also has a strong grip on the phone. The TPU and TPE materials are relatively lightweight compared to metal or other hard materials, and the use of these materials for the frame does not significantly increase the weight of the protective case, which helps maintain the lightness of the phone case and meets the needs of modern users for lightweight and portable devices. The tempered glass used as the material for the back panel 700 has extremely high transparency and excellent wear resistance, which can provide a clear visual effect. At the same time, the high hardness of tempered glass can effectively resist scratches and wear and tear during daily use, protecting the ink screen from damage. In addition, the upper end of the frame 600 is integrally formed with a camera unit, which extends from the frame 600 away from the mounting plate 300.

[0053] In this embodiment, to achieve the basic function of a protective cover while facilitating user operation of the mobile phone 120 within the protective case 100, the protective case 100 is provided with a speaker hole, a camera hole, a power button hole, a volume button hole, and a charging port. When the mobile phone 120 is assembled within the receiving slot 110, the speaker hole, camera hole, power button hole, volume button hole, and charging port correspond to the speaker, camera, power button, volume button, and charging port on the mobile phone 120, respectively. Optionally, the protective case 100 is also provided with a lanyard hole.

[0054] A positioning boss 900 is provided on the back of the protective shell 100 . A bracket 910 is provided on the positioning boss 900 . The positioning boss 900 is hinged to the bracket 910 .

[0055] To free the user's hands and support the phone 120 installed in the protective case 100 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 hingedly connected to the positioning boss 900. When the bracket 910 forms an angle with the protective case 100 through the hinge, the bracket 910 is used to support the phone 120 in the protective case 100. The camera hole in the protective case 100 is penetrated by the positioning boss 900, and the positioning boss 900 is arranged around the edge of the camera hole. The bracket 910 can be hinged to the positioning boss 900 via a damping shaft.

[0056] The back side of the protective shell 100 is provided with protrusions 920 close to the edge thereof and is provided on both sides of the positioning boss 900 in the width direction.

[0057] The protrusions 920 are provided in two groups, and the two groups of protrusions 920 together form the expansion portion of the bracket 910.

[0058] A protrusion 920 is provided on the back side of the protective shell 100 near the edge, and the positioning boss 900 is wrapped on both sides near the edge to protect the camera, and the two sets of protrusions 920 together form the expansion part of the bracket 910. The purpose of this design is to integrate an expandable bracket 910 in the protective shell 100 so that the device can be supported at different angles when placed. The protrusion 920 is set on the back side near the edge, which can effectively utilize the space at the edge of the shell and avoid affecting the overall thickness of the protective shell 100.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
