Description

Technical Field

[0001] The present application relates to the technical field of anti-peeping display screens, and in particular to anti-peeping display screens and electronic devices. Background Art

[0002] With the development of technology, more and more electronic devices are equipped with cameras to meet users' needs for taking photos, recording videos and making video calls. These cameras not only improve the user experience, but also play an important role in many application scenarios, such as remote work, online education and home monitoring. However, the existence of cameras also brings hidden dangers in terms of privacy and security. Since the cameras on most electronic devices are exposed for a long time, they are vulnerable to hacker attacks and malicious use, thereby leaking users' sensitive information.

[0003] To address this issue, there are already a variety of solutions on the market to protect user privacy. Some common methods include physical shielding devices, software encryption technology, and virtualization technology. The physical shielding device is usually a small manually operated slider or flap that can cover the camera when it is not in use; software encryption technology encrypts the transmitted data through complex algorithms to prevent the data from being intercepted during transmission; virtualization technology simulates the camera and generates images without actually turning on the camera, so as to deceive potential attackers.

[0004] Although the above methods have improved the security of the camera to a certain extent, there are still obvious shortcomings. In particular, although the physical shielding device is simple and easy to use, it may be inconvenient when used frequently, and it cannot completely prevent dust from entering the camera, resulting in a decrease in camera performance. In addition, most existing physical shielding devices can only provide protection when the camera is idle, and there is still a lack of effective and immediate protection measures when the camera needs to quickly switch usage scenarios. Therefore, how to design a convenient and efficient camera anti-peeping device has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The purpose of this application is to overcome the above technical problems and provide an anti-peeping display screen and an electronic device.

[0006] By adopting the above technical solution, the anti-peeping display screen can automatically close the through hole when the camera is not in use, effectively preventing the external environment from interfering with the camera and potential safety risks. Specifically, the shielding plate can tightly cover the through hole to prevent external light from entering and affecting the display effect or causing privacy leakage; the blocking frame can not only effectively prevent external dust and impurities from entering the accommodating cavity, but also ensure that the camera is not disturbed when in use, thereby improving the service life and imaging quality of the camera. At the same time, this design allows the camera to be quickly turned on and used normally when needed, improving the convenience and reliability of use.

[0007] Preferably, a control component is also provided in the accommodating cavity, and the control component is used to control the rotation of the rotating shaft. The control component includes a control slider, a transmission rack and a transmission gear. The control slider is slidably arranged in the accommodating cavity, and the control slider movably passes through the outer wall of the display screen body. The transmission rack is fixed to the side wall of the control slider, and the transmission gear is rotatably carried in the accommodating cavity. The transmission gear and the transmission rack are meshed with each other, and the transmission gear is connected to the rotating shaft for synchronous rotation.

[0008] By adopting the above technical solution, the control slider can slide along the outer wall of the display body through external operation, drive the transmission rack to move, and then drive the transmission gear to rotate. Since the transmission gear is connected to the rotating shaft in synchronous rotation, the rotation angle of the rotating shaft can be accurately controlled, thereby realizing the alternating movement of the shielding plate and the blocking frame to ensure the safety and privacy of the camera. This design not only improves the user's convenience, but also effectively prevents the camera from being illegally used, thereby improving the overall safety of electronic equipment.

[0009] Preferably, a worm is coaxially fixed to the rotating shaft, a worm wheel is rotatably carried in the accommodating cavity, the worm wheel and the worm are meshed with each other, and the transmission gear and the worm wheel rotate synchronously.

[0010] By adopting the above technical solution, the meshing structure of the worm and the worm wheel can effectively transmit the rotational motion of the shaft, ensure the accurate switching of the shielding plate and the blocking frame, and improve the reliability and stability of the anti-peeping function. At the same time, connecting the worm wheel with the transmission gear further enhances the coordination of the system, making the user operation easier and smoother.

[0011] Preferably, a mounting plate is provided in the accommodating cavity, the anti-peeping component and the control component are both provided on the mounting plate, a return spring is fixed to the side wall of the mounting plate, and the bottom of the control slider is fixed to the return spring.

[0012] By adopting the above technical solution, the setting of the mounting plate enables the anti-peeping component and the control component to be integrated into one, improving the compactness and stability of the structure. The use of the reset spring in conjunction with the control slider can automatically return to the initial position after the operation is completed, thereby ensuring the reliability and convenience of the device. Specifically, when the user manually pushes the control slider, the reset spring is compressed. After releasing the thrust, the elastic force of the reset spring drives the control slider back to its original position, ensuring that the baffle or blocking frame correctly closes the through hole, effectively preventing the external environment from affecting the camera.

[0013] Preferably, a cleaning assembly is also provided in the accommodating cavity, and the cleaning assembly includes a cleaning brush and a collection box, the cleaning brush is fixed to the side wall of the rotating shaft and is circumferentially arranged with the baffle plate, the collection box is fixed to the cavity wall of the accommodating cavity, the collection box is located on one side of the camera for collecting dust and impurities, a dust outlet is provided on the side wall of the display screen body, and an opening and closing door is connected to the side wall of the collection box, and the opening and closing door is used to cover the dust outlet.

[0014] By adopting the above technical solution, the cleaning component can effectively remove dust and impurities on the surface of the camera. Specifically, the cleaning brush is fixed to the side wall of the rotating shaft and is arranged circumferentially with the baffle plate. When the baffle plate moves to the through-hole position, the cleaning brush can scrape off the dust and impurities on the camera and introduce them into the collection box. The collection box is fixed to the cavity wall of the accommodating cavity, located on one side of the camera, and can effectively receive the dust and impurities scraped from the surface of the camera. A dust outlet is provided on the side wall of the display screen body, and an opening and closing door is provided on the side wall of the dust outlet. The opening and closing door is used to cover the dust outlet, ensuring that when the dust and impurities in the collection box need to be cleaned, the dust and impurities can be conveniently discharged by opening the opening and closing door, thereby keeping the camera clean and clear and improving the user experience.

[0015] Preferably, the mounting plate is slidably disposed in the accommodating cavity, a push rod is fixed to the side wall of the mounting plate, a sliding block is slidably disposed on the side wall of the collecting box, a first inclined surface is disposed at one end of the sliding block, and when the mounting plate is displaced a certain distance, the push rod slides relative to the first inclined surface, and the other end of the sliding block lifts up the opening and closing door.

[0016] By adopting the above technical solution, when the mounting plate slides in the accommodating cavity, the push rod will contact the first inclined surface of the sliding block and slide relative to it, thereby pushing the sliding block to move, and then the other end of the sliding block lifts up the opening and closing door. This design not only realizes the automatic opening of the opening and closing door, and facilitates the discharge of dust and impurities, but also has a simple and reliable structure, and improves the overall performance and user experience of the anti-peeping display screen.

[0017] Preferably, a torsion spring is provided between the collection box and the opening and closing door, and the torsion spring is used to achieve resetting of the opening and closing door.

[0018] By adopting the above technical solution, the torsion spring provided between the collection box and the opening and closing door can ensure that the opening and closing door is always in a closed state when not acted upon by external forces, effectively preventing external dust from entering the collection box, thereby keeping the internal environment clean. At the same time, when it is necessary to clean the dust and impurities in the collection box, the operation of opening the opening and closing door is more convenient and can be completed without additional tools or complicated operations, thereby improving user experience and maintenance efficiency.

[0019] Preferably, the bottom of the groove of the collection box is arranged to be inclined, and the direction of inclination is from top to bottom from the inner side of the collection box toward the dust outlet.

[0020] By adopting the above technical solution, the bottom of the groove of the collection box is arranged at an angle, so that dust and impurities can slide toward the dust outlet more smoothly, thereby improving the cleaning efficiency and effect.

[0021] Preferably, a pull ring is fixed to the end of the control slider.

[0022] By adopting the above technical solution, the additional pull ring allows the user to more conveniently pull the control slider through manual operation, thereby realizing the function of covering or opening the camera, thereby improving the user experience.

[0030] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0031] The present application embodiment discloses an anti-peeping display screen. Figure 1 and Figure 2 The anti-peeping display screen and the electronic device include a display screen body 1, a receiving cavity is provided in the display screen body 1, a camera 2 is installed in the receiving cavity, the camera 2 is used for shooting and recording the display screen, a through hole 12 connected to the receiving cavity is opened on the side wall of the display screen body 1, and the position of the camera 2 corresponds to the position of the through hole 12 so that the camera 2 can transmit light.

[0032] Reference Figure 2 and Figure 3 On the other hand, two guide columns 11 are fixed to the inner wall of the accommodating cavity. The guide columns 11 are slidably provided with a mounting plate 3 in the vertical direction. The mounting plate 3 is vertically arranged. An anti-peeping component 4 is arranged on the mounting plate 3. The anti-peeping component 4 includes a rotating shaft 41, a shielding plate 42 and a blocking frame 43. The rotating shaft 41 is rotatably carried in the accommodating cavity. The shielding plate 42 and the blocking frame 43 are circumferentially distributed on both sides of the rotating shaft 41 and are fixed to the rotating shaft 41. By rotating the rotating shaft 41, the shielding plate 42 and the blocking frame 43 are alternately moved to the position of the through hole 12. The shielding plate 42 can cover the through hole 12. The blocking frame 43 is centrally arranged. The two side walls of the blocking frame 43 can respectively fit with the cavity wall of the accommodating cavity and the outer peripheral wall of the camera 2 to block the gap between the through hole 12 and the accommodating cavity.

[0033] Therefore, the anti-peeping display screen can automatically close the through hole 12 when the camera 2 is not in use, effectively preventing the external environment from interfering with the camera 2 and potential safety risks. Specifically, the shielding plate 42 can tightly cover the through hole 12 to prevent external light from entering and affecting the display effect or causing privacy leakage; the blocking frame 43 can not only effectively prevent external dust and impurities from entering the accommodating cavity, but also ensure that the camera 2 is not disturbed when in use, thereby improving the service life and imaging quality of the camera 2. At the same time, this design allows the camera 2 to be quickly turned on and used normally when needed, improving the convenience and reliability of use.

[0034] Specifically, the rotating shaft 41 can be a cylindrical member made of metal, or plastic or other high-strength materials. Both ends of the rotating shaft 41 can be fixed on the inner wall of the accommodating cavity by bearings to ensure its smooth rotation. The shielding plate 42 can be a rectangular plate made of an opaque material, such as ABS plastic or aluminum alloy, which has a good light-shielding effect. The blocking frame 43 is made of a flexible material, such as silicone or rubber, and can fit tightly against the outer peripheral wall of the camera 2 and the cavity wall of the accommodating cavity to effectively prevent dust from entering.

[0035] Furthermore, a control component 5 is also provided on the mounting plate 3, and the control component 5 includes a control slider 51, a transmission rack 52 and a transmission gear 53. The side wall of the mounting plate 3 is fixed with a base body 31, and the control slider 51 is slidably provided on the base body 31 along the vertical direction. The control slider 51 moves through the outer wall of the display screen body 1. At the same time, a connecting block is fixed to the side wall of the control slider 51, and the transmission rack 52 is vertically fixed to the connecting block and provided along the vertical direction.

[0036] Correspondingly, the transmission gear 53 is rotatably carried on the side wall of the mounting plate 3 , the transmission gear 53 and the transmission rack 52 are meshed with each other, and the transmission gear 53 is synchronously rotatably connected with the rotating shaft 41 .

[0037] Therefore, the control slider 51 can slide along the outer wall of the display body 1 through external operation, drive the transmission rack 52 to move, and then drive the transmission gear 53 to rotate. Since the transmission gear 53 is connected to the rotating shaft 41 in synchronous rotation, the rotation angle of the rotating shaft 41 can be accurately controlled, so as to achieve the alternating movement of the shielding plate 42 and the blocking frame 43, ensuring the safety and privacy of the camera 2. This design not only improves the convenience of use for users, but also effectively prevents the camera 2 from being illegally used, thereby improving the overall safety of the electronic device.

[0038] Specifically, a Maltese mechanism 7 is arranged on the mounting plate 3, and the driving wheel of the Maltese mechanism 7 is coaxially fixed with the transmission gear 53, and the driven wheel of the Maltese mechanism 7 is connected to the rotating shaft 41 for synchronous rotation. Correspondingly, two baffle plates 42 and two blocking frames 43 are each arranged, and the baffle plates 42 and the blocking frames 43 are circumferentially spaced on the outer periphery of the rotating shaft 41. Therefore, through the Maltese mechanism 7, when the control slider 51 controls the displacement of the transmission rack 52, the transmission gear 53 rotates synchronously to drive the driving wheel of the Maltese mechanism 7 to rotate. Due to the indexing characteristics of the Maltese mechanism 7, when the driving wheel of the Maltese mechanism 7 rotates one circle, the driven wheel of the Maltese mechanism 7 rotates one quarter of a circle to achieve indexing. Therefore, after a single press by the user, the baffle plate 42 and the blocking frame 43 can be switched back and forth.

[0039] Furthermore, a worm 8 is coaxially fixed to the rotating shaft 41, and a worm wheel 9 is rotatably carried on the side wall of the mounting plate 3. The worm wheel 9 and the worm 8 are meshed with each other. A transmission shaft 10 is arranged between the worm wheel 9 and the driven wheel of the Maltese mechanism 7, and the transmission shaft 10 is coaxially connected to the transmission gear 53 and the worm wheel 9 at the same time.

[0040] Therefore, the meshing structure of the worm 8 and the worm wheel 9 can effectively transmit the rotational motion of the rotating shaft 41, ensure the accurate switching of the baffle plate 42 and the blocking frame 43, and improve the transmission accuracy. In addition, due to the self-locking characteristics of the worm wheel 9 and the worm 8, the stability of the structure can be guaranteed. In addition, both the worm 8 and the worm wheel 9 are processed with high precision to ensure accurate meshing. The worm 8 is coaxially fixed to the rotating shaft 41 and connected by a keyway to ensure the effectiveness of the transmitted torque. The meshing ratio of the worm wheel 9 and the worm 8 can be adjusted according to actual needs to achieve the best deceleration effect.

[0041] Furthermore, a return spring 32 is fixed to the side wall of the seat body 31, and the bottom of the control slider 51 is fixed to the return spring 32. The return spring 32 is arranged in the vertical direction. The arrangement of the mounting plate 3 enables the anti-peeping component 4 and the control component 5 to be integrated into one body, thereby improving the compactness and stability of the structure. The return spring 32 and the control slider 51 are used in conjunction, and can automatically return to the initial position after the operation is completed, thereby ensuring the reliability and convenience of the device. Specifically, when the user manually pushes the control slider 51, the return spring 32 is compressed. After releasing the thrust, the elastic force of the return spring 32 drives the control slider 51 back to its original position, ensuring that the shielding plate 42 or the blocking frame 43 correctly closes the through hole 12, effectively preventing the external environment from affecting the camera 2.

[0042] On the other hand, a cleaning component 6 is also provided in the accommodating cavity, and the cleaning component 6 includes a cleaning brush 61 and a collecting box 62. The cleaning brush 61 is fixed to the side wall of the rotating shaft 41 and is circumferentially arranged with the shielding plate 42. The collecting box 62 is fixed to the cavity wall of the accommodating cavity. The collecting box 62 is located on one side of the camera 2 for collecting dust and impurities. A dust outlet is provided on the side wall of the display screen body 1, and an opening and closing door 13 is connected to the side wall of the collecting box 62. The opening and closing door 13 is used to cover the dust outlet.

[0043] Specifically, the cleaning brush 61 can be a soft nylon brush or microfiber cloth, which can effectively remove dust and stains on the surface of the camera 2. The cleaning brush 61 is fixed to the side wall of the rotating shaft 41, and continuously cleans the camera 2 as the rotating shaft 41 rotates. The collection box 62 is made of hard plastic and has a certain dust storage capacity. Regular cleaning can keep the camera 2 clean and tidy.

[0044] The cleaning component 6 can effectively remove dust and impurities on the surface of the camera 2. Specifically, the cleaning brush 61 is fixed to the side wall of the rotating shaft 41 and is circumferentially arranged with the baffle plate 42. When the baffle plate 42 moves to the position of the through hole 12, the cleaning brush 61 can scrape off the dust and impurities on the camera 2 and introduce them into the collection box 62. The collection box 62 is fixed to the cavity wall of the accommodating cavity, located on one side of the camera 2, and can effectively receive the dust and impurities scraped from the surface of the camera 2. A dust outlet is provided on the side wall of the display screen body 1, and an opening and closing door 13 is provided on the side wall of the dust outlet. The opening and closing door 13 is used to cover the dust outlet to ensure that when it is necessary to clean the dust and impurities in the collection box 62, the dust and impurities can be conveniently discharged by opening the opening and closing door 13, thereby keeping the camera 2 clean and clear and improving the user experience.

[0045] Furthermore, the mounting plate 3 is slidably arranged in the accommodating cavity, a push rod 33 is fixed to the side wall of the mounting plate 3, a sliding block 621 is slidably arranged on the side wall of the collecting box 62, and a first inclined surface is arranged at one end of the sliding block 621. When the mounting plate 3 is displaced for a certain distance, a second inclined surface is arranged on the push rod 33, the second inclined surface slides relative to the first inclined surface, and the other end of the sliding block 621 lifts up the opening and closing door 13.

[0046] When the mounting plate 3 slides in the accommodating cavity, the push rod 33 contacts the first inclined surface of the sliding block 621 and slides relative to it, thereby pushing the sliding block 621 to move, and then the other end of the sliding block 621 lifts up the opening and closing door 13. This design not only realizes the automatic opening of the opening and closing door 13 and facilitates the discharge of dust and impurities, but also has a simple and reliable structure, improving the overall performance and user experience of the anti-peeping display screen.

[0047] Correspondingly, a hooking portion 311 is provided on the seat body 31, and a protrusion 511 is fixed to the side wall of the control slider 51. When the control slider 51 moves upward to a certain distance, the protrusion 511 abuts against the control slider 51, and the control slider 51 continues to be lifted, thereby driving the entire mounting plate 3 to move upward. The second inclined surface and the first inclined surface always maintain abutment during the above process.

[0048] Therefore, by adding the reset spring 32 and the push rod 33, the automatic reset function of the control slider 51 and the mounting plate 3 is realized, which greatly simplifies the user's operation steps. At the same time, this design can also automatically control the opening and closing of the door 13 without additional manual operation, thereby improving the automation of the system and the user experience.

[0049] Furthermore, a pull ring 512 is fixed to the end of the control slider 51 , and the user can more conveniently pull the control slider 51 by holding the pull ring 512 .

[0050] On the other hand, in order to ensure the stability of the mounting plate 3, a supporting block 111 is fixed to the end of the guide column 11, and magnets are provided on the upper surface of the supporting block 111 and the bottom of the mounting plate 3. The stability of the mounting plate 3 can be ensured by the mutual attraction of the magnets.

[0051] The present application also discloses an electronic device, including the above-mentioned display screen body 1, which can not only quickly open the camera 2 for shooting or video calls when needed, but also automatically close and cover the camera 2 when the camera 2 is not needed, effectively preventing external malicious access and sneak shots, and protecting user privacy. At the same time, the built-in cleaning component 6 can remove dust and stains on the surface of the camera 2 during each switching process, ensuring that the camera 2 is always in the best working condition, and improving the user experience.

[0052] The implementation principle of the anti-peeping display screen and the electronic device in the embodiment of the present application is: The rotation of the rotating shaft 41 realizes the alternate movement of the shielding plate 42 and the blocking frame 43, so that the through hole 12 can be effectively blocked when the camera 2 is not in use to protect the user's privacy. At the same time, the design of the blocking frame 43 can not only prevent dust from entering, but also ensure the normal use of the camera 2, thereby improving the reliability of the entire system and the user experience.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
