A tablet computer with face recognition function

Abstract

This utility model discloses a tablet computer with facial recognition function, relating to the field of tablet computers. The utility model includes a tablet computer body. Functional mechanisms are arranged above and below the outer surface of the body. Through a cooperative control structure of a sliding privacy mechanism and the functional mechanisms, the privacy film moves along the pull-out groove trajectory, triggering the elastic deformation of a deformation piece. This directly drives the locking / separation action of the magnetic card slot and the magnetic card block, achieving precise switching between the privacy film's protective and disassembly states. The oblique deformation of the deformation piece, combined with the pull-out trajectory limitation, ensures that the privacy film always moves along a predetermined path, avoiding the risk of traditional magnetic films shifting and falling off or scratching the screen during forced removal. Simultaneously, the mechanical locking mechanism of the magnetic buckle replaces chemical adhesion, ensuring the privacy film remains undamaged during repeated disassembly and reassembly.

Description

Technical Field

[0001] This utility model relates to the field of tablet computers, specifically a tablet computer with facial recognition function. Background Technology

[0002] Tablet computers are modern smart electronic devices that combine portability and multifunctionality. They integrate powerful computing capabilities, rich software applications, and high-definition display effects, meeting people's needs in learning, work, entertainment, and other aspects. Among them, facial recognition is a major technological breakthrough for tablet computers in the fields of security authentication and convenient operation. With the help of high-precision cameras and advanced facial recognition algorithms, it can quickly and accurately identify the user's facial features to realize operations such as device unlocking, application login, and payment verification. This not only greatly improves the convenience of use for users, but also provides reliable protection for device data security, allowing users to enjoy the convenience brought by technology without worrying about the risk of information leakage.

[0003] However, many people tend to use privacy screen protectors on their tablets to prevent others from peeking at the screen and ensure the privacy of their personal information. But in reality, there are many situations where screen content needs to be shared, such as when discussing solutions in a team and needing to show design ideas to colleagues, or when teachers need to present learning materials to students in the classroom. In these cases, traditional privacy screen protectors, which are directly and tightly attached to the screen surface, are extremely inconvenient to remove temporarily for sharing, and the process of tearing them off can easily damage the privacy screen protector, rendering it unusable. New magnetic privacy screen protectors have also appeared on the market. These privacy screen protectors are attached to the tablet screen using a magnetic device, which seems to solve the problem of traditional privacy screen protectors being difficult to reuse to some extent. However, the magnetic force is difficult to control precisely. If the magnetic force is too weak, the privacy screen protector can easily loosen and fall off due to slight bumps, shaking, or movement of the tablet during normal use. This not only affects the user experience but may also damage or lose the privacy screen protector. If the magnetic force is too strong, it may cause scratches or other damage to the tablet screen or frame during installation and removal. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a tablet computer with face recognition function to solve the technical problems of traditional tablet computers. When sharing screen content, the traditional direct-adhesive privacy film is inconvenient to remove temporarily, is easily damaged, and cannot be reused. The new magnetic privacy film is difficult to control the magnetic force, and is easy to loosen and fall off or cause scratches and damage to the tablet computer screen and frame.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tablet computer with face recognition function, comprising a tablet computer, the tablet computer comprising a main body, functional mechanisms provided above and below the outer surface of the main body, the functional mechanisms comprising a first card sleeve and a second card sleeve, the first card sleeve and the second card sleeve being fixedly connected to the main body, the inner sides of the first card sleeve and the second card sleeve being formed with pull grooves, the edges of the first card sleeve and the second card sleeve being provided with a first arc-shaped chamfer, and a magnetic card block being provided on one side of the outer surface of the main body;

[0006] A privacy mechanism is slidably connected in the pull-out slot. The privacy mechanism includes a privacy diaphragm. The top and bottom of the privacy diaphragm are provided with a second arc-shaped chamfer, and the second arc-shaped chamfer of the privacy diaphragm is adapted to the first arc-shaped chamfer.

[0007] The privacy film has a deformable sheet on one side, and the deformable sheet has a magnetic card slot.

[0008] By adopting the above technical solution, the pull-out grooves of the upper and lower functional mechanisms of the main body form a stable slide rail. When the privacy film slides along the groove, the second arc-shaped chamfer and the first arc-shaped chamfer surface are matched to guide the positioning. The integrated design of the deformation sheet and the magnetic card slot realizes the simplification of components.

[0009] Furthermore, the privacy film slides into the pull-out slot, which can cause the magnetic card slot to engage with the magnetic card block, making it easy to lock the privacy film.

[0010] By adopting the above technical solution, when the privacy film is fully slid into the pull-out slot, the magnetic card slot and the magnetic card block automatically adsorb and engage, achieving zero-operation-force locking.

[0011] Furthermore, the deformable piece is used for slight upward oblique deformation, and after deformation, it can cause the magnetic card slot to move away from the magnetic card block, making it easier to detach the anti-peeping mechanism from the functional mechanism.

[0012] By adopting the above technical solution, the deformation sheet deforms upwards at an angle to generate displacement, directly releasing the magnetic card slot from the magnetic card block lock, and completing the disassembly in a single step.

[0013] Furthermore, the back of the main body is provided with a back shell, and a magnetic sheet is attached to the middle of the back of the back shell by an adhesive. The magnetic sheet can be magnetically attracted to the privacy film, which is convenient for temporarily placing the removed privacy film.

[0014] By adopting the above technical solution, the privacy film can be adsorbed by the magnetic strip on the back cover, realizing tool-free temporary storage of the privacy film.

[0015] Furthermore, a display screen is provided in the middle of the outer surface of the main body, and a front-facing camera is provided on the other side of the outer surface of the main body.

[0016] By adopting the above technical solution, the display screen in the middle of the outer surface of the main body is separated from the side front camera, ensuring that the display and imaging functions operate independently.

[0017] Furthermore, a rear camera is provided on the upper back of the rear shell, and both the rear camera and the front camera can be used for face recognition.

[0018] By adopting the above technical solution, the rear camera on the upper back of the back cover and the front camera form a dual recognition source, covering multi-angle face verification scenarios.

[0019] Furthermore, the front-facing camera is located outside the coverage area of ​​the privacy film's sliding path; the rear-facing camera is located outside the magnetic attraction area of ​​the magnetic film.

[0020] By adopting the above technical solution, the front camera is located outside the privacy film sliding coverage area, and the rear camera is far away from the magnetic film's effective area, ensuring that the camera is always available.

[0021] Furthermore, the second curved chamfer is used to fit the first curved chamfer, which is used to prevent hand cuts.

[0022] By adopting the above technical solution, the second arc-shaped chamfer adapts to the first arc-shaped chamfer to form a smooth transition, and the first arc-shaped chamfer eliminates the hard edge feel when held.

[0023] In summary, the present invention has the following main advantages:

[0024] This invention utilizes a collaborative control structure combining a sliding privacy screen protector and a functional mechanism. The privacy screen protector moves along the pull-out groove trajectory, triggering the elastic deformation of the deformation plate. This directly drives the locking or separating action of the magnetic card slot and the magnetic card block, achieving precise switching between the privacy screen protector's protective and disassembly states. The oblique deformation of the deformation plate, combined with the pull-out trajectory limitation, ensures that the privacy screen protector always moves along a predetermined path, avoiding the risks of traditional magnetic films shifting and falling off or being forcibly removed and scratching the screen. At the same time, the mechanical locking mechanism of the magnetic buckle replaces chemical adhesive, ensuring the privacy screen protector remains undamaged during repeated disassembly and reassembly.

[0025] This invention features a magnetic suction plate that magnetically holds the removed privacy film to the back of the device, eliminating the hassle of searching for a container or surface when temporarily placing the film. Furthermore, the magnetic suction plate is located in the center of the back cover, utilizing the device's own flat surface as a storage carrier without increasing the device's size.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Example 1: A tablet computer with facial recognition function, such as Figure 1-4 As shown, the device includes a tablet computer 1, which includes a main body 101. Functional mechanisms 3 are provided above and below the outer surface of the main body 101. The functional mechanisms 3 include a first card sleeve 301 and a second card sleeve 302. The first card sleeve 301 and the second card sleeve 302 are fixedly connected to the main body 101. A pull-out groove 303 is formed on the inner side of the first card sleeve 301 and the second card sleeve 302. A first arc-shaped chamfer 304 is provided on the edge of the first card sleeve 301 and the second card sleeve 302. A magnetic card block 305 is provided on one side of the outer surface of the main body 101.

[0033] A privacy mechanism 4 is slidably connected in the pull-out slot 303. The privacy mechanism 4 includes a privacy diaphragm 401. The top and bottom of the privacy diaphragm 401 are provided with a second arc-shaped chamfer 402, and the second arc-shaped chamfer 402 of the privacy diaphragm 401 is adapted to the first arc-shaped chamfer 304.

[0034] A deformable piece 403 is provided on one side of the privacy film 401, and a magnetic card slot 404 is provided on the deformable piece 403. The functional mechanism 3 provided above and below the outer surface of the main body 101 forms a rigid pull-out groove 303 through the first card sleeve 301 and the second card sleeve 302, providing a low-friction sliding path for the privacy mechanism 4. The second arc-shaped chamfer 402 at the top and bottom of the privacy film 401 is coupled with the first arc-shaped chamfer 304 at the edge of the card sleeve, eliminating hard contact points. The deformable piece 403 is integrated into the side of the privacy film 401 and has a built-in magnetic card slot 404. The structure is compact, avoiding additional accessories and reducing production complexity.

[0035] See Figure 1 , Figure 2 The privacy film 401 slides into the pull-out groove 303, which can cause the magnetic card slot 404 to engage with the magnetic card block 305, making it easy to lock the privacy film 401. When the privacy film 401 slides into the final position along the pull-out groove 303, the magnetic card slot 404 is guided by the groove body and precisely aligned with the magnetic card block 305 of the main body 101. The magnetic attraction force drives the two to automatically attract and engage, forming a mechanical interlock. This process does not require additional force from the user, and the locked state can resist accidental external force to disengage, improving the working stability of the privacy film.

[0036] See Figure 1 , Figure 2 The deformation piece 403 is used for slight upward oblique deformation, and after deformation, it can cause the magnetic card slot 404 to move away from the magnetic card block 305, making it easy to disengage the anti-peeping mechanism 4 from the functional mechanism 3. Manually pressing the deformation piece 403 triggers its upward oblique elastic deformation, which drives the magnetic card slot 404 to generate a vertical displacement component, forcibly separating the meshing surface of the magnetic card slot 404 and the magnetic card block 305. Before the deformation is reset, the magnetic attraction is isolated by space, and the anti-peeping mechanism 4 can slide freely along the pull-out groove 303, avoiding the disadvantage of traditional disassembly requiring two-hand operation.

[0037] Example 2: See Figure 3 , Figure 4 The back of the main body 101 is provided with a back shell 104. A magnetic strip 2 is attached to the middle of the back of the back shell 104 by adhesive. The magnetic strip 2 can be magnetically attracted to the privacy film 401, which is convenient for temporary placement of the removed privacy film 401. The magnetic strip 2 is fixed to the back of the back shell 104 by adhesive. The removed privacy film 401 can be directly attracted to the surface of the magnetic strip 2 by magnetic force. The magnetic surface is flush with the plane of the back shell, so that the privacy film 401 fits the body for storage, avoiding loss or scratches, and realizing orderly management of disassembled parts.

[0038] See Figure 1 , Figure 2The main body 101 has a display screen 102 in the middle of its outer surface and a front-facing camera 103 on the other side of its outer surface. The display screen 102 is unobstructed in the middle of the outer surface of the main body 101, and the front-facing camera 103 is arranged separately on the other side. The physical separation ensures that the screen operation area and the camera acquisition area do not interfere with each other. The privacy film 401 only covers the display screen 102, and the front-facing camera 103 is always exposed to the working environment to ensure that face recognition is continuously available.

[0039] See Figure 1 , Figure 4 The rear camera 105 is located on the upper back of the back cover 104. Both the rear camera 105 and the front camera can be used for face recognition. The rear camera 105 on the upper back of the back cover 104 and the front camera 103 of the main body 101 form a dual-channel image acquisition system. The corresponding camera can be activated to perform face recognition when the tablet is held horizontally or vertically. The independent layout of the dual modules avoids the risk of single-point failure and enhances the reliability of biometric authentication.

[0040] See Figure 3 , Figure 4 The front camera 103 is located outside the coverage area of ​​the sliding path of the privacy film 401; the rear camera 105 is located outside the magnetic attraction area of ​​the magnetic absorbing piece 2. The front camera 103 is arranged outside the physical coverage area of ​​the sliding path of the privacy film 401 to ensure that the lens is not obstructed when the privacy film is installed or removed; the rear camera 105 is positioned in the magnetic field area of ​​the magnetic absorbing piece 2 to avoid magnetic interference with the internal electronic components of the lens module and to ensure that the dual cameras work stably throughout the face recognition process.

[0041] See Figure 1 , Figure 4 The second arc-shaped chamfer 402 is used to adapt to the first arc-shaped chamfer 304. The first arc-shaped chamfer 304 is used to avoid cutting hands. The first arc-shaped chamfer 304 on the edges of the first card sleeve 301 and the second card sleeve 302 matches the curvature of the second arc-shaped chamfer 402 on the privacy film 401, forming a continuous curved surface during assembly to avoid misalignment and friction damage to the parts. The first arc-shaped chamfer 304 also weakens the sharp angle of the outer edge of the functional mechanism 3, so that there are no hard edge indentations on the contact surface of the hand when the user holds it, improving the operating comfort.

[0042] The implementation principle of this embodiment is as follows: First, the privacy film 401 slides into the pull-out groove 303 formed by the first sleeve 301 and the second sleeve 302. The second arc-shaped chamfer 402 at the top of the privacy film 401 fits against the curved surface of the first arc-shaped chamfer 304 at the edge of the sleeve, achieving physical alignment guidance. When the privacy film 401 slides into the working position, the magnetic card slot 404 on its side automatically magnetically engages with the magnetic card block 305 on the surface of the main body 101 under the trajectory limit, completing mechanical locking, so that the privacy film 401 completely covers the display screen 102 to form an optical privacy layer.

[0043] When switching to screen sharing mode, manually press the deformation piece 403 of the privacy screen 401 to make it undergo upward oblique elastic deformation. The deformation piece 403 drives the magnetic card slot 404 to move perpendicular to the pulling direction, forcibly separating the magnetic card slot 404 from the locking surface of the magnetic card block 305. After unlocking, the privacy screen 401 slides out along the linear trajectory of the pull-out groove 303, and the display screen 102 is fully exposed to the visible environment.

[0044] After being removed, the privacy screen 401 is temporarily fixed to the surface of the magnetic clasp 2 on the back cover 104 by magnetic adsorption to prevent it from being lost during movement. The front camera 103 is located outside the sliding path of the privacy screen 401, and the rear camera 105 avoids the magnetic force area of ​​the magnetic clasp 2 to ensure that the face recognition process is not interfered with by the operation of the privacy mechanism. When restoring the privacy state, the privacy screen 401 slides back into the pull-out slot 303, triggering the magnetic locking, achieving zero-loss reassembly.
