Technical Field

[0001] This application belongs to the technical field of electronic products and accessories, specifically relating to finger reading mirrors, protective cases, and electronic device components. Background Technology

[0002] A finger-reading mirror is typically installed on the front-facing camera of electronic devices such as tablets, smartphones, learning machines, and e-readers. The front-facing camera captures the content reflected by the finger-reading mirror to view the paper, thereby enabling functions such as finger reading.

[0003] Existing finger-reading mirrors work by projecting and reflecting the image onto a camera and a mirror. In order to fully capture the content on the paper, the mirror needs to be at a certain angle. Therefore, the main body of the finger-reading mirror is at a preset angle relative to the electronic device. However, the Hall effect devices that trigger the electronic device inside the finger-reading mirror are usually placed close to the electronic device, resulting in a bulky overall structure for the finger-reading mirror. Utility Model Content

[0004] This application provides a finger reader, a protective case, and electronic equipment components to solve the technical problem of the overall bulky structure of the finger reader.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: a finger-reading mirror for an electronic device with a camera, the finger-reading mirror comprising: a supporting body; a reflective body connected to the supporting body, the reflective body extending in a flat plate shape, the reflective body having a reflective surface, and a trigger element disposed within the reflective body; wherein, when the finger-reading mirror is in working state, the supporting body is used to maintain relative fixation with the electronic device, the reflective surface of the reflective body faces the electronic device, and the trigger element is located on the side of the reflective surface away from the electronic device and triggers the sensor of the electronic device.

[0006] According to one embodiment of this application, the finger reader is used to be installed on the electronic device or the protective case of the electronic device, so as to remain relatively fixed with the electronic device in the working state, and the area of ​​the electronic device or the protective case for the finger reader to be installed is the mounting part; a first magnetic element is provided in the support body, and the first magnetic element can be attracted to the mounting part.

[0009] According to one embodiment of this application, the support body has a limiting groove formed on the side facing the mounting portion, and the mounting portion has a limiting protrusion that matches the limiting groove.

[0010] According to one embodiment of this application, the finger-reading mirror includes a first housing and a second housing that are fastened together. The first magnetic element and the trigger element are disposed in the first housing and the second housing. The finger-reading mirror also includes a reflective lens, which is embedded in the outer surface of the second housing to form the reflective surface.

[0011] To solve the above-mentioned technical problems, another technical solution adopted in this application is: a protective cover, wherein the protective cover has a storage groove, and the above-mentioned finger reading mirror can be placed in the storage groove.

Both the reflective body and the finger-reading mirror are thinner and lighter, occupying less space and facilitating storage when not in use. Furthermore, the flat shape of the reflective body and the placement of the trigger element on the back of the reflective surface ensure unobstructed reflection, allowing the camera to capture the reflected content more completely, thus improving the accuracy and efficiency of the finger-reading function.

Detailed Implementation

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Through long-term research, the applicant has found that in order to fully capture the content on paper, the main body of the reading mirror is at a preset angle relative to the electronic device. However, the triggers that trigger the electronic device inside the reading mirror are usually located close to the electronic device. This not only makes the overall structure of the reading mirror heavy, but also, if the triggers are placed on both sides of the reflective surface of the reading mirror, they will also obstruct the reflection range of the lens to a certain extent.

[0022] Please see Figures 1 to 4 , Figure 1 This is a front view structural diagram of a finger-reading mirror provided in an embodiment of this application; Figure 2 This is an exploded view of a finger-reading mirror provided in one embodiment of this application; Figure 3 This is a cross-sectional structural diagram of a finger-reading mirror provided in an embodiment of this application in its working state on an electronic device; Figure 4 yes Figure 3 Enlarged view of part A in the middle.

[0023] One embodiment of this application provides a finger-reading mirror 100 for use with an electronic device 310 equipped with a camera, to cooperate with the camera in capturing the content of paper on a desktop. The finger-reading mirror 100 includes a support body 110 and a reflective body 120. The reflective body 120 is connected to the support body 110, extends in a flat plate shape, has a reflective surface 121, and a trigger 122 is disposed within the reflective body 120. When the finger-reading mirror 100 is in working condition, the support body 110 is used to maintain relative fixation with the electronic device 310, the reflective body 120 maintains a predetermined angle with the electronic device 310, the reflective surface 121 of the reflective body 120 faces the electronic device 310, and the trigger 122 is located on the side of the reflective surface 121 away from the electronic device 310 and triggers the sensor 330 of the electronic device 310.

[0024] As can be seen from the above solution, in this application, the trigger 122 of the reflective body 120 is positioned on the reflective surface 121 away from the electronic device 310. The reflective body 120 can be designed as a flat plate. The reflective body 120 does not need to have a local protrusion design to allow the trigger 122 to be parallel to and attached to the electronic device 310. Both the reflective body 120 and the finger-reading mirror 100 are thinner and lighter, occupying less space, which is beneficial for the storage of the finger-reading mirror 100 when not in use. In addition, the flat shape of the reflective body 120 and the arrangement of the trigger 122 on the back of the reflective surface 121 also ensure that the reflective area of ​​the reflective surface 121 is unobstructed. The camera can capture the paper content reflected by the reflective surface 121 more completely, improving the accuracy and efficiency of the finger-reading function.

[0025] Specifically, the camera can be a front-facing camera.

[0026] It should be noted that the triggering of the sensor 330 by the trigger 122 usually has a redundancy. The technical solution of this application can overcome the technical bias by setting the trigger 122 on the side of the reflective surface 121 away from the electronic device 310. This not only maintains the triggering and release of the sensor 330 by the trigger 122, but also avoids the obstruction of the reflective surface 121 and achieves the overall thinness of the finger reading mirror 100.

[0027] The specific position of the trigger 122 relative to the sensor 330 within the reflective body 120 can be adjusted according to triggering needs. The size of the trigger 122 and the sensitivity of the sensor 330 can be selected according to actual triggering needs, so that the trigger 122 is in a balanced state of sensitive triggering and timely release of the sensor 330. Specifically, when the finger reader 100 is installed on the electronic device 310 and is in working state, the reflective body 120 and the electronic device 310 are at a predetermined angle, and the trigger 122 can promptly trigger the sensor 330, so that the electronic device 310 can sense the installation of the finger reader 100; when the finger reader 100 is removed from the electronic device 310 and is in non-working state, the finger reader 100 is relatively far away from the electronic device 310, and the trigger 122 can promptly release the sensor 330 to avoid misidentification by the sensor 330.

[0028] Specifically, the sensor 330 can be a Hall element disposed inside the electronic device 310, and the trigger 122 is a magnet disposed inside the reflective body 120. The Hall element can accurately sense changes in the magnetic field generated by the magnet. When the reading mirror 100 is installed on the electronic device 310 and is in working condition, the magnet inside the reflective body 120 approaches the Hall element inside the electronic device 310. The Hall element detects that the magnetic field strength reaches a certain threshold and generates a corresponding electrical signal. The electronic device 310, through analysis and processing of this electrical signal, senses the installation of the reading mirror 100 and can control the camera to turn on and capture the paper content reflected by the reading mirror 100. When the reading mirror 100 is removed from the electronic device 310 and is in a non-working state, the magnet inside the reflective body 120 moves away from the electronic device 310, and the magnetic field strength detected by the Hall element rapidly weakens. When the magnetic field strength is lower than the set threshold, the electrical signal output by the Hall element also changes. The electronic device 310 determines that the reading mirror 100 has been removed, thus avoiding false recognition by the sensor 330.

[0029] It should also be noted that the flat shape of the reflective body 120 means that the overall appearance of the reflective body 120 is flat and the thickness is relatively uniform, but there may be slight depressions or protrusions in some areas. However, there are no obvious protruding or bent areas of the reflective body 120 that affect its storage.

[0030] To ensure the finger reader 100 remains relatively fixed to the electronic device 310 during operation, the finger reader 100 is typically mounted on the electronic device 310 or its protective case 210. For ease of description, the area on the electronic device 310 or protective case 210 where the finger reader 100 is mounted is referred to as the mounting portion 101. The mounting portion 101 is the area near the camera of the electronic device 310. A first magnetic element 111 is provided inside the support body 110, which can be attracted to the mounting portion 101. The attraction and fixation between the first magnetic element 111 and the mounting portion 101 ensures the stability of the finger reader 100 relative to the electronic device 310 during operation, preventing it from falling off due to slight shaking or collision. Simultaneously, the attraction and fixation between the first magnetic element 111 and the mounting portion 101 simplifies the installation and removal of the finger reader 100 from the electronic device 310, avoiding excessive resistance when removing the finger reader 100 and eliminating the need for additional tools.

[0031] Specifically, the mounting part 101 may contain a magnetic material that is attracted by the first magnetic component 111; the mounting part 101 may also contain a magnetic component that is attracted to the first magnetic component 111.

[0032] In some embodiments, the first magnetic element 111 includes two first magnets 1111, with opposite magnetic poles facing the mounting portion 101. A mounting magnetic element 102 is provided within the mounting portion 101, and the mounting magnetic element 102 includes two mounting magnets 103, with the magnetic poles of the two mounting magnets 103 corresponding to the magnetic poles of the first magnets 1111. By providing two first magnets 1111 with opposite magnetic poles and matching mounting magnets 103 with opposite magnetic poles in the mounting portion 101, the finger-reading mirror 100 can be installed correctly without misalignment. Specifically, when the finger reader 100 approaches the mounting part 101 at the wrong angle, the incorrect magnetic pole direction will generate a repulsive force, preventing the user from installing the finger reader 100 at the wrong angle on the mounting part 101; however, when the finger reader 100 approaches the mounting part 101 at the correct angle, the first magnet 1111 and the mounting magnet 103 will naturally attract each other, guiding the user to easily complete the alignment and installation of the finger reader 100, thus lowering the user's usage threshold.

[0033] To enhance the adsorption effect of the first magnet 1111 and the mounting magnet 103, they should be positioned as close as possible and relatively parallel. However, when the mounting part 101 of the electronic device 310 or the protective cover 210 is equipped with the mounting magnet 103, in order to avoid the mounting part 101 protruding too vertically, the mounting magnet 103 is positioned flat relative to the top of the electronic device 310. Since the finger reader 100 is installed at a predetermined angle on the electronic device 310, in order to make the first magnet 1111 closer to the mounting magnet 103, the first magnet 1111 is inclined relative to the trigger 122 towards the mounting magnet 103 within the support body 110. The adsorption force between the first magnet 1111 and the mounting magnet 103 is stronger, which is beneficial to the installation stability of the finger reader 100.

[0034] Meanwhile, for the sake of thinner and lighter design and easier storage of the finger-reading mirror 100 of this application, the supporting body 110 and the reflective body 120 are integrally formed. The side of the supporting body 110 and the reflective surface 121 on the same side are coplanar with the reflective body 120. The side of the supporting body 110 opposite to the reflective surface 121 protrudes outward to accommodate the first magnet 1111. At this time, when storing the finger-reading mirror 100, the side of the finger-reading mirror 100 with the reflective surface 121 is generally flat, which is convenient for storage and protects the reflective surface 121. The side of the finger-reading mirror 100 away from the reflective surface 121 protrudes outward in part, which not only facilitates the placement of the first magnet 1111 inside, but also forms a handle on the outside, making it easy for the user to take out the finger-reading mirror 100 in the stored state.

[0035] Therefore, by setting the first magnet 1111 in the support body 110 at an angle relative to the trigger 122 toward the mounting magnet 103, this application can achieve a balance between making the finger reading mirror 100 thinner, the installation stability of the finger reading mirror 100, and the ease of taking out the finger reading mirror 100 after storage.

[0036] In some embodiments, the support body 110 is partially recessed on the side facing the mounting portion 101 to form a limiting groove 112, and the mounting portion 101 has a limiting protrusion 104 that matches the limiting groove 112. The matching design of the limiting groove 112 on the finger reader 100 and the limiting protrusion 104 on the electronic device 310 or the protective case 210 further enhances the accuracy of the finger reader 100 installation and the stability during operation. When the mounting part 101 is part of the electronic device 310, the mounting part 101 can be the top of the electronic device 310, and the limiting protrusion 104 of the mounting part 101 is the right-angled bevel or the arc-shaped bevel of the top of the electronic device 310. The supporting body 110 has a structurally matching limiting groove 112 on the side facing the mounting part 101. When the mounting part 101 is part of the protective sleeve 210, the mounting part 101 can be additionally provided with a limiting protrusion 104 that matches the limiting groove 112 to increase the stability of the finger reader 100 during operation.

[0037] In some embodiments, the finger reader 100 includes a first housing 130 and a second housing 140 that are fastened together. A first magnetic element 111 and a trigger element 122 are disposed within the first housing 130 and the second housing 140. The finger reader 100 also includes a reflective lens 150, which is embedded in the outer surface of the second housing 140 to form the reflective surface 121.

[0038] Specifically, the reflector 150 is fixed to the outer surface of the second housing 140 by adhesive 114. The second housing 140 is partially recessed to form a limiting groove 112. The first housing 130 is partially protruding outward to accommodate the inclined first magnet 1111. The first magnetic element 111 and the trigger element 122 can be glued to the inside of the first housing 130 and / or the second housing 140, and the first magnetic element 111 and the trigger element 122 can also be clamped inside the first housing 130 and / or the second housing 140 by structural limiting.

[0040] Another embodiment of this application provides a protective sleeve 210 with a storage slot 211, in which the finger reader 100 can be placed. The finger reader 100 adopts the finger reader 100 of any of the above embodiments. In the non-working state when the finger reader 100 is not in use, it can be stored in the storage slot 211, which not only protects the finger reader 100 but also prevents it from being lost. The finger reader 100 can be taken out and used at any time. In addition, the finger reader 100 of this application is thin and light, so a matching storage slot 211 can be opened in the protective sleeve 210 for storage. When the finger reader 100 is placed in the storage slot 211, the side of the finger reader 100 with the reflective surface 121 is arranged inward, and the side of the finger reader 100 away from the reflective surface 121 protrudes outward to form a handle.

[0041] At this time, the mounting part 101 is a local area on the protective cover 210 corresponding to the top of the electronic device 310, designed to match the finger reader 100.

[0042] In this application, the storage slot 211 is formed inside the protective sleeve 210 and communicates with the outside through the opening of the storage slot 211. The depth direction of the storage slot 211 is parallel to the overall electronic device 310. In other words, the storage slot 211 is pocket-shaped, so only the opening side of the storage slot 211 is exposed to the outside. When the finger reader 100 is stored in the storage slot 211, only one end of the finger reader 100 is exposed on the opening side, and the other areas are surrounded and protected within the storage slot 211. This not only enhances the protection of the finger reader 100 and effectively prevents it from being accidentally scratched or bumped during daily storage, but also improves the stability of the finger reader 100 when stored in the storage slot 211. The finger reader 100 is not easily dislodged from the storage slot 211 due to slight shaking or vibration.

[0043] Specifically, the storage slot 211 is formed in the protective cover plate (e.g., the protective back plate 202) of the protective cover 210. By opening the storage slot 211 in the thickness direction of the protective cover plate, multi-directional protection of the finger reader 100 can be achieved. When the overall thickness of the protective cover plate is relatively thin, it can be locally thickened at the storage slot 211 to have sufficient space to open the storage slot 211.

[0044] Alternatively, the storage groove 211 can be formed inside the protective cover plate (e.g., the protective back plate 202) of the protective cover 210, that is, on the side of the protective cover plate facing the electronic device 310. The storage groove 211 fits with the outer wall of the electronic device 310, exposing the finger reader 100 only at the opening. After the protective cover 210 is installed on the electronic device 310, the storage groove 211 formed by the protective cover plate utilizes the outer wall of the electronic device 310 to form a multi-directional surrounding protection for the finger reader 211. By forming the storage groove 211 on the side of the protective cover plate of the protective cover 120 near the electronic device 310, the thickness of the protective cover 210 at the storage groove 211 can be reduced.

[0045] To facilitate the placement and removal of the pointer mirror 100 in the storage slot 211, the width of the pointer mirror 100 gradually decreases from the supporting body 110 to the reflecting body 120 (see [reference]). Figure 1 The internal width of the storage slot 211 gradually decreases from the opening to the bottom. When the finger reading mirror 100 needs to be placed into the storage slot 211, the narrower end of the reflective body 120 can enter the opening first, and then the finger reading mirror 100 can be placed completely into the storage slot 211 relatively easily.

[0046] To improve the stability of the reading mirror 100 within the storage slot 211, a magnetic element 212 is provided at the bottom of the storage slot 211, and a second magnetic element 113 is also provided at the end of the reflective body 120 away from the supporting body 110. When the reading mirror 100 is placed in the storage slot 211, the magnetic element 212 and the second magnetic element 113 attract each other, thereby firmly fixing the reading mirror 100 inside the storage slot 211 and effectively preventing the reading mirror 100 from shaking or falling out within the storage slot 211. Even when the electronic device 310 is moved or inverted, the reading mirror 100 can still be stably stored in the storage slot 211 of the protective cover 210.

[0047] The second magnetic component 113 can be integrally formed with the trigger component 122, serving as a single part. It can both form a magnetic field triggering sensor 330 and attract the magnetic component 212 at the bottom of the storage slot 211. Alternatively, the second magnetic component 113 can be separate from the trigger component 122, forming two distinct components.

[0048] Specifically, the second magnetic element 113 is also disposed between the first housing 130 and the second housing 140.

[0049] In some embodiments, the protective cover 210 includes a protective panel 201, a protective back panel 202, and a flexible connecting portion 203 connecting the protective panel 201 and the protective back panel 202. When the electronic device 310 is not in use, the protective back panel 202 protects the back side of the electronic device 310, and the protective panel 201 protects the screen side of the electronic device 310. The protective panel 201 includes three folding plates 2011 connected in sequence. When the electronic device 310 is in use, the three folding plates 2011 can be folded backward to form a triangular structure, at which time the protective back panel 202 can support the electronic device 310 for upright use.

[0050] Among them, the folding plate 2011 that is far away from the flexible connection part 203 among the three folding plates 2011 can be adsorbed and fixed with the protective back plate 202, which improves the stability of the protective cover 210 supporting the electronic device 310 to stand, and thus improves the stability of the finger reading mirror 100 in the working state.

[0051] Specifically, the folding plate 2011 furthest from the flexible connection 203 among the three folding plates 2011 is provided with a first pair of magnetic attracting elements 2012, and the protective back plate 202 is provided with a second pair of magnetic attracting elements 2021 at the corresponding position. When the three folding plates 2011 can be folded backward to form a triangular structure, the first pair of magnetic attracting elements 2012 and the second pair of magnetic attracting elements 2021 are attracted and fixed.

[0052] The storage slot 211 may be formed on the protective back panel 202. Of course, in other embodiments, the storage slot 211 may also be formed on the protective panel 201.

[0054] Another embodiment of this application provides an electronic device assembly 300. The electronic device assembly 300 includes the finger reader 100 of any of the above embodiments of the electronic device 310. In this case, the mounting portion 101 is a partial area on the top of the electronic device 310, designed to match the finger reader 100. When the finger reader 100 needs to be stored in a non-working state, it can be magnetically attached to an area of ​​the electronic device 310 away from the camera, forming a magnetically absorbed storage.

[0055] The electronic device assembly 300 may further include the electronic device 310 and the protective sleeve 210 in any of the above embodiments. The protective sleeve 210 can protect the electronic device 310. In this case, the mounting portion 101 is a partial area on the top of the electronic device 310 corresponding to the protective sleeve 210, designed to match the finger reader 100.

[0056] The electronic device 310 includes a camera and a sensor 330. The sensor 330 can sense the proximity of the trigger 122 when the finger reader 100 is installed, thereby generating a feedback signal and controlling the camera to turn on and capture the paper content reflected by the finger reader 100.

[0057] Among them, electronic device 310 can be electronic products such as learning machine, e-reader, tablet computer, and smartphone.

[0058] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted. In addition, the orientations or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships that are commonly used when the product of this application is in use. They are only for the purpose of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0059] It is understood that in this document, "multiple" means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. The term "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0060] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
