Description

Technical Field

[0001] This invention relates to the field of image display device mounting equipment technology, and more particularly to an image display device. Background Technology

[0002] In the use of image display devices, especially in applications requiring multi-angle observation and operation, it is often necessary to flexibly adjust the installation position and viewing angle of the display screen. However, in most existing image display devices, the light-shielding structure is mostly a fixed baffle or a simple hinge, usually directly installed on the display screen frame or bracket by screws or clips. Once such light-shielding components are installed, their shading angle, expansion range, and position are fixed, making it difficult to adjust them according to changes in the position of the display screen.

[0003] Fixed light-shielding structures cannot adapt to changes in lighting conditions after the display screen is adjusted in multiple degrees of freedom, which can easily lead to a decrease in light-shielding effect and glare interference, affecting the user's clear observation of images and precise operation. Therefore, there is an urgent need for an image display device with adjustable light-shielding capabilities, strong structural adaptability, and stable installation to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing fixed light-shielding structures cannot adapt to changes in the lighting environment after the display screen is adjusted in multiple degrees of freedom, resulting in a decrease in light-shielding effect and serious glare interference. The invention proposes an image display device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an image display device, including a frame and a display screen, wherein the frame is equipped with a support mechanism for mounting the display screen and a shielding mechanism for preventing glare from the display screen, and the frame is also equipped with a mounting mechanism for fixing the frame. The support mechanism includes a mounting frame rotatably mounted on the frame, guide rails symmetrically mounted on the mounting frame, two support frames respectively mounted on the guide rails by racks, the display screen located between the two support frames and fixed to the mounting frame by screws, and the mounting frame is also equipped with a limiting component that can limit the movement of the support frame.

[0006] This technical solution allows for flexible adjustment of the overall angle of the display screen by rotating the mounting brackets installed on the frame. Combined with symmetrically arranged guide rails and rack and pinion transmission, the two support brackets can move synchronously in opposite directions, making it suitable for clamping and fixing display screens of different sizes. This ensures installation stability and provides good dimensional adaptability.

[0007] The support frame moves smoothly on the guide rail via a rack and pinion mechanism. Dedicated limiting components effectively lock the support frame in place after it has been moved, preventing accidental displacement during installation or subsequent use and ensuring the accuracy and reliability of the display screen's installation position.

[0008] The support, shielding, and installation functions are integrated into a single, compact frame. The support mechanism focuses on the installation, fixation, and angle adjustment of the display screen, providing a stable foundation for subsequent operations such as shading.

[0009] As a further description of the above technical solution: the limiting component includes a gear and a fixing block disposed on the mounting bracket. The limiting block is disposed on the fixing block via a plug rod. A first spring is fixedly installed between the fixing block and the limiting block and is sleeved on the surface of the plug rod.

[0010] As a further description of the above technical solution: the first gear is rotatably mounted on the mounting bracket, and the limiting block is located between the teeth of the first gear. The two racks are located on both sides of the first gear and mesh with the first gear.

[0011] As a further description of the above technical solution: the shielding mechanism includes fixed frames symmetrically installed on the support frame, shielding plate one and shielding plate two are respectively rotatably installed on the corresponding fixed frames, a gear two is fixedly installed on the top of shielding plate one, and a gear three is rotatably installed on one of the fixed frames through a cylinder, and the cylinder and shielding plate two are connected by a synchronous belt.

[0012] As a further description of the above technical solution: the first and second shields are two-section structures, and the second gear and the third gear mesh with each other.

[0013] As a further description of the above technical solution: one of the support frames is also equipped with a flipping component; The flipping assembly includes a rotating rod and a circular block mounted on a support frame. A folding plate is fixedly mounted on the rotating rod. A gear four is fixedly connected to one end of the rotating rod that extends into the interior of the circular block, as well as a paddle that is used in conjunction with the gear four.

[0014] As a further description of the above technical solution: the rectangular frame is fixedly installed on the circular block, the recessed frame is set inside the rectangular frame through the connecting rod, and the third spring is fixedly installed between the recessed frame and the rectangular frame and sleeved on the surface of the connecting rod.

[0015] As a further description of the above technical solution: the paddle is rotatably mounted on the recessed frame, and a torsion spring is installed at the connection between the paddle and the recessed frame. A stop bar is fixedly installed on the recessed frame, and the stop bar is located above the paddle.

[0016] As a further description of the above technical solution: the folding plate is also equipped with auxiliary components; The auxiliary component includes symmetrically opened positioning holes on the folding plate, an extension plate slidably installed inside the folding plate, symmetrically opened mounting grooves on both sides of the extension plate, a positioning block set in the mounting groove by a second spring, and one end of the positioning block extending to the outside of the extension plate located in the positioning hole.

[0017] As a further description of the above technical solution: the installation mechanism includes a crossbeam fixedly installed on the frame, a support frame mounted on the frame via a rotating component, and a base plate rotatably mounted on the support frame.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By coordinating the rotating mounting bracket and the installation mechanism, the display screen can be adjusted in multiple degrees of freedom. Two support frames provide initial fixation and stable support during installation, and limiting components ensure reliable locking, enhancing flexibility and stability. The multi-axis rotating structure of the installation mechanism adapts to various installation environments such as desktops and walls, enabling multi-angle fixation. The first and second shielding plates rotate synchronously via gears two and three, and a timing belt, forming a double-sided light-shielding structure. The flipping assembly uses gear four and a lever structure to adjust and position the top light-shielding plate, achieving multi-directional light shading and enhancing anti-glare capabilities. The folding plate contains a retractable extension plate, which, through auxiliary components, allows for length adjustment, positioning, and locking, thereby expanding the light-shielding range and improving structural adaptability.

[0032] 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.

[0033] Reference Figure 1 - Figure 12 The image display device provided in this embodiment includes a frame 10 and a display screen 11. The frame 10 is equipped with a support mechanism 20 for mounting the display screen 11 and a shielding mechanism 30 for preventing glare from the screen of the display screen 11. The frame 10 is also equipped with a mounting mechanism 40 for fixing the frame 10. The support mechanism 20 includes a mounting bracket 21 rotatably mounted on the frame 10. The mounting bracket 21 is fixed to the frame 10 with screws, and the angle of the display screen 11 can be adjusted by rotating the mounting bracket 21. Guide rails 22 are symmetrically mounted on the mounting bracket 21. Two support frames 23 are respectively mounted on the guide rails 22 via racks 24, which slide on the guide rails 22, thereby driving the support frames 23 to move. The display screen 11 is located between the two support frames 23 and is fixed to the mounting bracket 21 with screws. The mounting bracket 21 is also equipped with a limiting component 25 that can limit the movement of the support frames 23.

[0034] Reference Figure 12 The mounting mechanism 40 includes a crossbeam 41 fixedly mounted on the rack 10, which holds the mouse and keyboard. A support frame 42 is mounted on the rack 10 via a rotating component 43, which allows adjustment of the rack 10's mounting angle, and is secured with screws. A base plate 44 is rotatably mounted on the support frame 42, and is used for mounting and securing to a wall or other structure, thus integrating the entire device. The mounting position can be flexibly adjusted via the support frame 42, and is finally secured with screws.

[0035] Reference Figure 3 - Figure 6 The limiting component 25 includes a gear 251 and a fixing block 252 mounted on the mounting bracket 21. The limiting block 253 is mounted on the fixing block 252 via a rod 254. Pulling the rod 254 can cause the limiting block 253 to rise. A first spring 255 is fixedly mounted between the fixing block 252 and the limiting block 253 and is sleeved on the surface of the rod 254. The rebound force of the first spring 255 causes the limiting block 253 to return to its original position.

[0036] Gear 251 is rotatably mounted on mounting bracket 21, and limiting block 253 is located between the teeth of gear 251, limiting gear 251 and preventing it from rotating. Two racks 24 are located on both sides of gear 251 and mesh with it. When installing display screen 11, the insert rod 254 is pulled upward, causing limiting block 253 to rise. At this time, the first spring 255 is compressed, and limiting block 253 releases its restriction on gear 251. Then, one of the support brackets 23 is pulled, causing it to move the rack 24 connected to it. Through meshing, gear 251 begins to rotate, and the other support bracket 23 also moves through the rack 24 connected to it, thus moving the two support brackets 23 in opposite directions and increasing the distance between them. Display screen 11 is placed on one of the support brackets 23, and then the two support brackets 23 are moved in opposite directions to clamp display screen 11. Release the insertion rod 254. The rebound force of the first spring 255 resets the insertion rod 254 and the limiting block 253. The limiting block 253 re-inserts into the teeth of the gear 251, fixing the gear 251 in place. This allows the two support frames 23 to provide initial fixation and stable support for the display screen 11. Then, the display screen 11 is fixed to the mounting bracket 21 with screws, completing the installation.

[0037] Reference Figure 7 - Figure 8 The shielding mechanism 30 includes two sets of fixed frames 31 symmetrically mounted on the support frame 23, each set containing two frames. Shielding plate one 32 and shielding plate two 33 are rotatably mounted on their respective fixed frames 31, blocking light from both sides of the display screen 11. A gear two 34 is fixedly mounted on the top of shielding plate one 32, and a gear three 35 is rotatably mounted on one of the fixed frames 31 via a cylinder, with the gear three 35 fixedly connected to the cylinder. The cylinder and shielding plate two 33 are connected via a synchronous belt 36. Through the transmission of the synchronous belt 36, the gear three 35 drives the shielding plate two 33 to rotate synchronously when the cylinder rotates.

[0038] The first shield 32 and the second shield 33 are two-section structures with a sliding connection in the middle, allowing the first shield 32 and the second shield 33 to extend and retract synchronously when the distance between the two support frames 23 is adjusted. The second gear 34 meshes with the third gear 35. When glare appears on the screen of the display 11, the first shield 32 is rotated towards the display 11. The first shield 32 drives the second gear 34 to rotate, and through meshing, the third gear 35 begins to rotate via the cylinder. Simultaneously, through the transmission of the synchronous belt 36, the third gear 35 drives the second shield 33 to rotate synchronously, thus causing the first shield 32 and the second shield 33 to rotate synchronously towards the display 11, blocking light from both sides of the display 11 and reducing glare on the screen.

[0039] Reference Figure 9 - Figure 10 One of the support frames 23 is also equipped with a flip assembly 37 to prevent glare from the top of the display screen 11.

[0040] The flipping assembly 37 includes a rotating rod 371 and a circular block 372 mounted on a support frame 23. The rotating rod 371 is rotatably mounted on the support frame 23. A folding plate 373 is fixedly mounted on the rotating rod 371 and can rotate via the rotating rod 371. A gear 374 is fixedly connected to one end of the rotating rod 371 extending into the circular block 372, and a paddle 375 is used in conjunction with the gear 374. One end of the paddle 375 is located between the teeth of the gear 374, limiting the rotation of the gear 374 and thus preventing the rotating rod 371 from rotating.

[0041] A rectangular frame 376 is fixedly mounted on a circular block 372. A recessed frame 377 is disposed inside the rectangular frame 376 via a connecting rod 378. Pulling the connecting rod 378 can move the recessed frame 377. A third spring is fixedly mounted between the recessed frame 377 and the rectangular frame 376. The rebound force of the third spring causes the recessed frame 377 to return to its original position, and the third spring is sleeved on the surface of the connecting rod 378.

[0042] The paddle 375 is rotatably mounted on the recessed frame 377, and a torsion spring is installed at the connection between the paddle 375 and the recessed frame 377. The torsion spring allows the paddle 375 to return to its original position after being flipped. A stop bar is fixedly mounted on the recessed frame 377, and the stop bar is located above the paddle 375, preventing the paddle 375 from rotating upwards. When it is necessary to block the glare at the top of the display screen 11, the connecting rod 378 is pulled outwards, causing the connecting rod 378 to move the recessed frame 377 inwards towards the rectangular frame 376, causing the paddle 375 to move out of the teeth of the gear 4 374, releasing the restriction on the gear 4 374. Then, the folding plate 373 is rotated towards the display screen 11, causing the rotating rod 371 to drive the gear 4 374 to rotate. Once the folding plate 373 has rotated to the appropriate angle, the connecting rod 378 is released, allowing the third spring to return to its original state from compression. The spring's rebound force pushes the recessed bracket 377, causing the lever 375 to return to its original position, thus limiting the gear 4 374 again. This prevents the folding plate 373 from rotating further towards the display screen 11, providing support for the rotated folding plate 373. The rotated folding plate 373 can also block the top light from the display screen 11.

[0043] To reset the folding plate 373, simply rotate the folding plate 373. Due to the action of the stop lever, the paddle 375 cannot rotate upwards, but when the folding plate 373 is reset, the rotating rod 371 drives the gear 4 374 to continuously push this end of the paddle 375 downwards. Through the rebound force of the torsion spring, this end of the paddle 375 can continuously reset into the teeth of the gear 4 374.

[0044] Reference Figure 11 The folding plate 373 is also equipped with an auxiliary component 379 to increase the range of light blocking from the top of the display screen 11.

[0045] The auxiliary component 379 includes symmetrically arranged positioning holes 3791 on the folding plate 373. An extension plate 3792 is slidably mounted inside the folding plate 373, allowing the extension plate 3792 to be pulled outwards from the inside of the folding plate 373, thereby increasing the range of light blocking from the top of the display screen 11. The extension plate 3792 has symmetrically arranged mounting grooves on both sides. A positioning block 3793 is positioned within the mounting groove by a second spring 3794, and the positioning block 3793 is reset by the rebound force of the second spring 3794. One end of the positioning block 3793 extending to the outside of the extension plate 3792 is located within the positioning hole 3791, and this end is hemispherical. When the extension plate 3792 is pulled outwards, the hemispherical end of the positioning block 3793 is compressed by the positioning hole 3791 and retracts, releasing the restriction on the extension plate 3792. Once the extension plate 3792 has moved to the appropriate position, the rebound force of the second spring 3794 causes the positioning block 3793 to reset, and the hemispherical end is reinserted into the corresponding positioning hole 3791, thereby limiting the extension plate 3792. The extended plate 3792 can be pulled out to increase the range of light blocking from the top of the display screen 11.

[0046] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
