Description

Technical Field

[0001] This invention relates to the field of digital television stand technology, specifically to an adjustable anti-glare stand for digital televisions. Background Technology

[0002] With the popularization of digital TV technology and its development towards high definition and large screens, users' demands for viewing comfort and device intelligence continue to rise. As the core display device in the living room, the placement angle, installation stability, and visual experience of digital TVs directly affect the user experience. In daily use scenarios, natural light and indoor lighting in the living room can easily create mirror reflections on the TV screen, causing problems such as screen glare, washed-out images, and blurred details. Prolonged viewing can easily lead to visual fatigue and, in severe cases, even affect vision health. Most existing TV stands are fixed structures or only support simple manual height and tilt adjustments, unable to adjust the screen angle in real time according to changes in ambient light. Some adjustable stands rely on manual knobs, clips, and other mechanical methods for adjustment, which are cumbersome to operate and have low adjustment precision, making it difficult to quickly match changes in light and eliminate glare. At the same time, traditional stands are prone to problems such as TV center of gravity shift, uneven force on the bracket, and insecure clamping during adjustment, posing safety hazards such as tipping over and bracket deformation.

[0003] Therefore, this invention proposes an adjustable anti-glare base for digital televisions. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable anti-glare stand for digital televisions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable anti-glare stand for digital televisions, comprising a digital television and a stand, wherein a bracket is symmetrically and fixedly installed on the bottom of the digital television, and a movable platform is movably installed on the bottom of the bracket. A fixing component is provided between the movable platform and the bracket, and a reinforcing component is provided on the fixing component. The movable platform is disposed on the stand, the stand is fixedly installed on a television cabinet, a control screen is disposed on the stand, and an ambient light sensor is disposed on the digital television, wherein the ambient light sensor and the control screen are electrically connected. Preferably, the base has a control cavity and a protective cavity, and the protective cavity and the control cavity are arranged adjacent to each other. A cylinder is fixedly installed in the protective cavity, and a heat dissipation hole is provided on the inner side of the protective cavity. A telescopic rod is provided on the cylinder, and the telescopic rod extends through into the control cavity and is fixedly connected to the control cavity.

[0006] Preferably, the fixing component includes a shaped cavity, which is opened inside the movable platform. A semi-circular block is rotatably connected to the upper end of the shaped cavity. The shaped block is detachably connected to the center of the upper surface of the semi-circular block. A rotating shaft is rotatably connected to the center of the shaped block. One end of the rotating shaft is fixedly connected to the side wall of the movable platform.

[0007] Preferably, an L-shaped clamp is symmetrically and fixedly connected to the upper end face of the semicircular block, and the bracket extends into the L-shaped clamp and is slidably connected to the L-shaped clamp.

[0008] Preferably, the upper surface of the irregular block is a counter-sloping shape, and a rubber pad is symmetrically fixedly connected to the upper surface of the irregular block, with the upper surface of the rubber pad and the lower surface of the bracket in contact.

[0009] Preferably, the reinforcement includes two fixing cavities, each of which is located inside the upper end of an L-shaped clamp. A screw cylinder is fixedly connected through the upper part of each fixing cavity. The screw cylinder extends through and is threadedly connected to a screw rod. The screw rod extends into one side of the L-shaped clamp and is rotatably connected to an L-shaped frame. A fixing plate is fixedly connected to the bottom of the L-shaped frame.

[0010] Preferably, a limiting rod is symmetrically fixedly connected to the top of the inner surface of the fixed cavity, and sliding holes are symmetrically opened on the L-shaped frame. The limiting rod extends through the sliding hole and is slidably connected to the sliding hole. A limiting block is fixedly connected to one end of the limiting rod extending through the sliding hole.

[0011] Preferably, the base has symmetrical straight grooves, and multiple racks are fixedly connected at equal intervals in the straight grooves. A rotating rod is rotatably connected in the irregular cavity. The rotating rod extends through and is fixedly connected to a gear. The semicircular surface of the semicircular block has equally spaced arc-shaped toothed holes, and the gears and toothed holes are meshed together.

[0012] Preferably, the digital television is rotatable, with a rotation angle range of ±3 degrees to ±8 degrees and a single adjustment step of 0.5 degrees to 1 degree.

[0013] Preferably, the ambient light sensor is capable of detecting the glare trigger threshold of the environment, which is determined by the following formula: ; in, The dynamic glare trigger illuminance threshold; The base illuminance threshold is set at 300 lux; k is the angle correction factor, ranging from 2 to 5 lux / °. The angle between the incident ambient light ray and the screen normal; For a comfortable incident angle, the value is taken as 0°~15°; when the real-time detected ambient illuminance E≥ When this occurs, it is identified as glare and the adjustment is initiated.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, as the movable platform moves, the gears inside the platform move, intermittently contacting and being continuously meshed with the rack, causing the gears to rotate intermittently. This intermittent rotation of the gears drives the semicircular block containing the gear holes to rotate, causing the digital TV on the semicircular block to slowly rotate counterclockwise, tilting it towards the viewer. This reduces glare without affecting the viewer's viewing experience. Once the ambient light sensor detects that the glare has subsided, the cylinder stops working, and the digital TV stops moving. This method automatically adjusts the angle of the digital TV based on the light data detected by the ambient light sensor, eliminating glare and achieving automatic anti-glare without manual operation by the viewer, thus improving the user experience. Furthermore, this method results in relatively small movement and rotation angles of the digital TV, without affecting the viewer's viewing experience. 2. This invention places the device inside a TV cabinet. The ambient light sensor on the digital TV can detect the intensity, direction, and angle of ambient light in real time and is controlled by a control screen. The control screen can adjust the threshold values ​​of the intensity, direction, and angle of light sensed by the ambient light sensor. When the intensity, direction, and angle of light sensed by the ambient light sensor reach the threshold values, it indicates that viewers of the digital TV are prone to glare. At this time, the ambient light sensor controls the cylinder to work through the control screen. The cylinder drives the telescopic rod to work. The movement of the telescopic rod moves the movable platform, and the digital TV above the movable platform moves, thus moving deeper into the TV cabinet. The side wall of the TV cabinet can block light to reduce glare from the digital TV. 3. The present invention features a digital television rotation angle range of ±3 degrees to ±8 degrees. This angle range is the optimal range that does not affect the viewing experience of the viewer and ensures that glare is avoided. The single adjustment step of 0.5 degrees to 1 degree refers to the rotation angle of the digital television under the influence of a single rack. 4. In this invention, when installing a digital TV, the bracket of the digital TV is inserted into the L-shaped clamp to limit the position of the digital TV. This can effectively prevent the digital TV from tipping over due to the shift of its center of gravity when it is moved or its angle is adjusted, making it safer and more practical. 5. The design of the irregular block in this invention can provide auxiliary support for the bottom bracket of the digital TV, preventing the bracket from breaking due to the shift of the center of gravity of the digital TV when it is moved or the angle is adjusted. This further protects the installation stability and safety of the digital TV and makes it more practical. 6. In this invention, the rubber pad fixedly connected to the upper end of the irregular block can make the supporting force on the bottom bracket of the digital TV more uniform, so that it is evenly stressed, and can prevent the paint from peeling off the outer surface of the bracket due to contact and squeezing with the irregular block, making it more practical. 7. In this invention, under the action of the screw barrel, the screw rotates and moves downward, thereby driving the L-shaped frame connected to it to move downward. The fixing plate at the lower end of the L-shaped frame moves downward, thereby squeezing the bracket and fixing the bracket, so as to further ensure the installation stability of the digital TV and prevent the digital TV from tipping over when moving.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 10 The present invention provides a technical solution: An adjustable anti-glare stand for digital televisions includes a digital television 1 and a base 13. A bracket 11 is symmetrically and fixedly mounted on the bottom of the digital television 1. A movable platform 12 is movably mounted on the bottom of the bracket 11. A fixing member is provided between the movable platform 12 and the bracket 11, and a reinforcing member is provided on the fixing member. The movable platform 12 is mounted on the base 13, which is fixedly mounted on a television cabinet. A control screen 14 is mounted on the base 13. An ambient light sensor 15 is mounted on the digital television 1, and the ambient light sensor 15 is electrically connected to the control screen 14.

[0019] As an embodiment of the present invention, as shown in the figure, a control cavity 2 is provided in the base 13, and a protective cavity 21 is provided in the base 13. The protective cavity 21 and the control cavity 2 are arranged adjacent to each other. A cylinder 23 is fixedly installed in the protective cavity 21. A heat dissipation hole 22 is provided on the inner side of the protective cavity 21. A telescopic rod 24 is provided on the cylinder 23. The telescopic rod 24 extends through into the control cavity 2 and is fixedly connected to the control cavity 2.

[0020] When in operation, this device is placed inside the TV cabinet. The ambient light sensor 15 on the digital TV 1 can detect the intensity, direction, and angle of ambient light in real time and is controlled by the control panel 14. The control panel 14 can adjust the threshold values ​​of the intensity, direction, and angle of light sensed by the ambient light sensor 15. When the intensity, direction, and angle of light sensed by the ambient light sensor 15 reach the threshold values, it indicates that viewers of the digital TV 1 are prone to glare. At this time, the ambient light sensor 15 controls the cylinder 23 to work through the control panel 14. The cylinder 23 drives the telescopic rod 24 to work. The movement of the telescopic rod 24 moves the movable platform 12, and the digital TV 1 above the movable platform 12 moves, thus moving deeper into the TV cabinet. The side wall of the TV cabinet can block the light to reduce the glare of the digital TV 1.

[0021] As an embodiment of the present invention, as shown in the figure, the fixing member includes a shaped cavity 72, which is formed inside the movable platform 12. A semi-circular block 74 is rotatably connected to the upper end of the shaped cavity 72. A shaped block 31 is detachably connected to the center of the upper surface of the semi-circular block 74. A rotating shaft 32 is rotatably connected to the center of the shaped block 31. One end of the rotating shaft 32 is fixedly connected to the side wall of the movable platform 12.

[0022] During operation, when installing the digital TV 1, the bracket 11 of the digital TV 1 is inserted into the L-shaped clamp 3 to limit the position of the digital TV 1. This effectively prevents the digital TV 1 from tipping over due to the shift of its center of gravity when moving and adjusting its angle, making it safer and more practical. The design of the irregular block 31 can provide auxiliary support for the bracket 11 at the bottom of the digital TV 1, preventing the bracket 11 from being subjected to additional stress and breaking due to the shift of the center of gravity of the digital TV 1 when it is moved and the angle is adjusted. This further protects the installation stability and safety of the digital TV 1 and makes it more practical. The design of the rotating shaft 32 connected to the irregular block 31, the rotating shaft 32 as the axis of rotation of the semicircular block 74 can provide rotational support for the semicircular block 74, so that the digital TV 1 can rotate smoothly.

[0023] As an embodiment of the present invention, as shown in the figure, the upper end face of the semicircular block 74 is symmetrically and fixedly connected with an L-shaped clamp 3, and the bracket 11 extends into the L-shaped clamp 3 and is slidably connected with the L-shaped clamp 3.

[0024] During operation, the rubber pad 4 fixedly connected to the upper end of the irregular block 31 can make the supporting force on the bottom bracket 11 of the digital TV 1 more uniform, so that it is evenly stressed, and can prevent the paint from peeling off the outer surface of the bracket 11 due to contact and squeezing with the irregular block 31, making it more practical.

[0025] As an embodiment of the present invention, as shown in the figure, the upper surface of the irregular block 31 is a counter-sloping shape, and a rubber pad 4 is symmetrically and fixedly connected to the upper surface of the irregular block 31. The upper surface of the rubber pad 4 is in contact with the lower surface of the bracket 11.

[0026] The reinforcement includes a fixing cavity 5, there are two fixing cavities 5, and each fixing cavity 5 is opened inside the upper end of an L-shaped clamp 3. A screw cylinder 54 is fixedly connected through the upper part of the fixing cavity 5. The screw cylinder 54 extends through and is threadedly connected to a screw rod 51. The screw rod 51 extends into one side of the L-shaped clamp 3 and is rotatably connected to an L-shaped frame 52. A fixing plate 53 is fixedly connected to the bottom of the L-shaped frame 52.

[0027] During operation, under the action of the screw 54, the screw 51 rotates and moves downward, thereby driving the L-shaped frame 52 connected to it to move downward. The fixing plate 53 at the lower end of the L-shaped frame 52 moves downward, thereby squeezing the bracket 11 and fixing the bracket 11, so as to further ensure the installation stability of the digital TV 1 and prevent the digital TV 1 from tipping over when moving.

[0028] As an embodiment of the present invention, as shown in the figure, a limiting rod 6 is symmetrically fixedly connected to the top of the inner surface of the fixed cavity 5, and a sliding hole 61 is symmetrically opened on the L-shaped frame 52. The limiting rod 6 extends through the sliding hole 61 and is slidably connected to the sliding hole 61. A limiting block 62 is fixedly connected to one end of the limiting rod 6 extending out of the sliding hole 61.

[0029] During operation, the design of the limiting rod 6 and the sliding hole 61 can guide and limit the movement path of the fixed plate 53 to prevent it from getting stuck and the digital TV 1 from being unstable.

[0030] As an embodiment of the present invention, as shown in the figure, the base 13 has symmetrically opened straight grooves 7, and multiple racks 71 are fixedly connected at equal intervals in the straight grooves 7. The irregular cavity 72 is rotatably connected to a rotating rod 76, and the rotating rod 76 extends through and is fixedly connected to a gear 73. The semicircular surface of the semicircular block 74 has equally spaced arc-shaped toothed holes 75, and the gear 73 and the toothed holes 75 are meshed and connected.

[0031] The ambient light sensor 15 can detect the glare trigger threshold of the environment, which is determined by the following formula: ; in, The dynamic glare trigger illuminance threshold; The base illuminance threshold is set at 300 lux; k is the angle correction factor, ranging from 2 to 5 lux / °. The angle between the incident ambient light ray and the screen normal; For a comfortable incident angle, the value is taken as 0°~15°; when the real-time detected ambient illuminance E≥ When this occurs, it is identified as glare and the adjustment is initiated.

[0032] During operation, as the movable platform 12 moves, the gear 73 inside the platform 12 moves. During this movement, the gear 73 intermittently contacts the rack 71 and is continuously meshed with and driven by the rack 71, causing the gear 73 to rotate intermittently. This intermittent rotation of the gear 73 drives the semicircular block 74 containing the toothed hole 75 to rotate. The digital television 1 on the semicircular block 74 then slowly rotates counterclockwise, tilting towards the viewer. This reduces glare without affecting the viewer's viewing experience. Once the ambient light sensor 15 detects that the glare has subsided, the cylinder 23 stops working, and the digital television 1 stops moving. This method automatically adjusts the angle of the digital television 1 based on the light data detected by the ambient light sensor 15, eliminating glare and achieving automatic anti-glare without manual operation by the viewer, thus improving the user experience. Furthermore, this method results in relatively small movement and rotation angles for the digital television 1, ensuring it does not affect the viewer's viewing experience.

[0033] As an embodiment of the present invention, as shown in the figure, the digital television 1 is capable of rotation, with a rotation angle range of ±3 degrees to ±8 degrees and a single adjustment step of 0.5 degrees to 1 degree.

[0034] When in operation, the digital TV 1 is designed to rotate within a range of ±3 degrees to ±8 degrees. This range is the optimal range that does not affect the viewing experience of the audience and ensures that glare is avoided. The single adjustment step of 0.5 degrees to 1 degree refers to the rotation angle of the digital TV 1 under the influence of a single rack 71.

[0035] Working principle: When in operation, this device is placed inside the TV cabinet. The ambient light sensor 15 on the digital TV 1 can detect the intensity, direction, and angle of the ambient light in real time and is controlled by the control panel 14. The control panel 14 can adjust the threshold of the intensity, direction, and angle of the light sensed by the ambient light sensor 15. When the intensity, direction, and angle of the light sensed by the ambient light sensor 15 reach the threshold, it means that the viewer of the digital TV 1 is prone to glare. At this time, the ambient light sensor 15 controls the cylinder 23 to work through the control panel 14. The cylinder 23 drives the telescopic rod 24 to work. The movement of the telescopic rod 24 drives the movable platform 12 to move. The digital TV 1 above the movable platform 12 moves, thus moving deeper into the TV cabinet. The side wall of the TV cabinet can block the light to reduce the glare of the digital TV 1. As the movable platform 12 moves, the gear 73 inside the platform 12 moves. During movement, the gear 73 intermittently contacts the rack 71 and is continuously meshed with and driven by the rack 71, causing the gear 73 to rotate intermittently. The intermittent rotation of the gear 73 drives the semicircular block 74 where the tooth hole 75 is located to rotate, and the digital TV 1 on the semicircular block 74 slowly rotates counterclockwise, that is, the digital TV 1 tilts towards the viewer, thereby reducing glare without affecting the viewer's viewing experience. After the ambient light sensor 15 detects that the glare has stopped, the cylinder 23 stops working, that is, the digital TV 1 stops moving. Using this method, the angle of the digital TV 1 can be automatically adjusted according to the light data detected by the ambient light sensor 15 to eliminate glare, thereby achieving automatic anti-glare without the need for manual operation by the viewer, improving the user experience. Moreover, using this method, the movement and rotation angle of the digital TV 1 are relatively small, which will not affect the viewer's viewing experience. The digital TV 1 is designed to rotate within a range of ±3° to ±8°. This range is the optimal range that does not affect the viewing experience and ensures that glare is avoided. The single adjustment step of 0.5° to 1° refers to the rotation angle of the digital TV 1 under the influence of a single rack 71. The design of the heat dissipation hole 22 can dissipate heat from the cylinder 23 during operation; When installing the digital TV 1, the bracket 11 of the digital TV 1 is inserted into the L-shaped clamp 3 to limit the position of the digital TV 1. This can effectively prevent the digital TV 1 from tipping over due to the shift of its center of gravity when it is moved or its angle is adjusted, making it safer and more practical. The design of the irregular block 31 can provide auxiliary support for the bracket 11 at the bottom of the digital TV 1, preventing the bracket 11 from being subjected to additional stress and breaking due to the shift of the center of gravity of the digital TV 1 when it is moved and the angle is adjusted. This further protects the installation stability and safety of the digital TV 1 and makes it more practical. The rubber pad 4 fixedly connected to the upper end of the irregular block 31 can make the supporting force on the bottom bracket 11 of the digital TV 1 more uniform, so that it is evenly stressed, and can prevent the paint from peeling off the outer surface of the bracket 11 due to contact and squeezing with the irregular block 31, making it more practical. The design of the rotating shaft 32 rotatably connected to the irregular block 31, the rotating shaft 32, as the axis of rotation of the semicircular block 74, can provide rotational support for the semicircular block 74, so that the digital TV 1 can rotate smoothly. Under the action of the screw 54, the screw 51 rotates and moves downward, thereby driving the L-shaped frame 52 connected to it to move downward. The fixing plate 53 at the lower end of the L-shaped frame 52 moves downward, thereby squeezing the bracket 11 and fixing the bracket 11, so as to further ensure the installation stability of the digital TV 1 and prevent the digital TV 1 from tipping over when moving. The design of the limiting rod 6 and the sliding hole 61 can guide and limit the movement path of the fixing plate 53 to prevent it from getting stuck and the digital TV 1 from being unstable.
