Description

An LCD screen with adjustable angle in multiple directions Technical Field

[0001] This application relates to display devices, and more particularly to an LCD screen with an adjustable angle in multiple directions. Background Technology

[0002] As a core display component of modern electronic devices, LCD screens are widely used in consumer electronics, industrial control, medical equipment, and other fields. With increasing user demands for display experience, screen adjustability has become a crucial indicator. LCD screens utilize the physical properties of liquid crystal materials to control the transmission of light, thereby enabling image display.

[0003] A search revealed Chinese Patent Publication No. CN221687150U, which discloses a dustproof LCD screen. The screen includes an LCD body with a fixed frame mounted on its frame. The fixed frame has a fully penetrating sliding groove on its side wall, within which a movable plate is slidably mounted. A cleaning cloth, which fits snugly against the LCD body, is mounted on the movable plate. Positioning components are located at the top and bottom of the vertical portion of the fixed frame, engaging with and disengaging from the positioning groove at the end of the movable plate. With this dustproof LCD screen, after the positioning block disengages from the positioning groove, it drives the movable plate to slide from one side to the other within the sliding groove. The cleaning cloth slides synchronously, effectively removing dust from the LCD body. Dust is pushed out from the other side without residue. The cleaning cloth, along with the movable plate, can be easily and quickly removed from the sliding groove for cleaning and replacement.

[0004] Although the aforementioned patent describes a method where, after the positioning block leaves the positioning groove, it drives the movable plate to slide from one side to the other within the sliding groove, and the dust cloth slides synchronously, thus removing dust from the LCD screen body, and the dust will be pushed out from the other side without leaving any residue, and the dust cloth can be easily and quickly replaced after being removed from the sliding groove along with the movable plate, the aforementioned text LCD screen requires adjustment of the angle in multiple directions according to different situations during use, which reduces its flexibility and stability. Therefore, a multi-directional adjustable LCD screen is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide an LCD screen with multi-directional adjustable angle, which addresses the problem that some devices cannot adjust the angle in multiple directions according to different situations during use.

[0030] The present application will be further described in detail below with reference to Figures 1-4.

[0031] Example: An LCD screen with multi-directional adjustable angle, referring to Figures 1 to 3, includes a supporting desktop 1 and a display screen 3. An angle adjustment mechanism 2 is fixedly connected to the top of the supporting desktop 1. The angle adjustment mechanism 2 includes a base plate 21, which is detachably connected to the top of the supporting desktop 1. A bearing 23 is rotatably connected inside the base plate 21. This detachable connection facilitates installation and maintenance. The bearing 23 and rotating connecting column 24 inside the base plate 21 provide basic support for the horizontal rotation of the supporting desktop 1. The rotating connecting column 24 is fixedly connected inside the bearing 23. When the supporting desktop 1 needs to be rotated horizontally, only a certain external force needs to be applied. The user can easily adjust the orientation of the supporting desktop 1 according to their needs and usage scenarios. The rotating connecting column 24, supported and cooperated with by the bearing 23, will drive the rotating seat 22 to rotate, thereby achieving the horizontal rotation of the supporting desktop 1. A rotating seat 22 is fixedly connected to the outer top of the rotating connecting column 24. One of the hinge components 28 is fixedly connected to the top of the rotating seat 22. The multi-stage hinge component 28... The design allows the support system for the desktop 1 to have multiple adjustable joints. These joints work together to increase the freedom and flexibility of adjustment. The first support arm 25 is rotatably connected inside the hinge 28, and another hinge 28 is fixedly connected to the top of the first support arm 25. The multi-stage hinge 28 can better distribute and balance the force, improving the stability of the entire support system. Even when the desktop 1 is tilted at a large angle or under heavy load, it can remain stable and will not easily shake or deform, thus extending the product's service life. The second support arm 26 is rotatably connected inside the other hinge 28. The angle formed by the different rotation angles of the first support arm 25 and the second support arm 26 is used to adjust the screen's tilt and lateral tilt relative to the angle adjustment mechanism 2. The tilt and lateral tilt adjustment functions provide users with a more flexible way to adjust the viewing angle. Adjusting the tilt angle of the desktop 1 allows the screen to be in the optimal viewing position, reducing eye fatigue.

[0032] Specifically, in the case of the multi-directional adjustable LCD screen, the base plate 21 of the angle adjustment mechanism 2 at the top of the tabletop 1 is detachably fixed to the tabletop 1. The bearing 23 inside provides the basis for rotation. When the tabletop 1 needs to be rotated horizontally, an external force is applied, and the rotating connecting column 24 fixed inside the bearing 23 drives the rotating seat 22 fixed on the top outer side to rotate under the cooperation of the bearing 23, thus achieving horizontal rotation. When adjusting the tilt and lateral angles, the first support arm 25 rotatably connected inside the hinge 28 fixed at the top of the rotating seat 22, and the second support arm 26 rotatably connected inside the hinge 28 at the top of the first support arm 25, play a role. By changing the angle between the first support arm 25 and the second support arm 26, the tilt and lateral angles of the tabletop 1 can be adjusted, thereby adjusting the display screen 3 to a suitable angle.

[0033] The base plate 21 is internally threaded with a fixing component 27, which includes multiple bolts 2701. The external threads of the bolts 2701 are connected to the inside of the base plate 21. The rear side of the display screen 3 is detachably connected to a connecting plate 2703, which is internally threaded with multiple bolts 2702. The fixing component 27, through the fastening action of the bolts 2701, tightly connects the various components of the angle adjustment mechanism 2 together, preventing the components from loosening due to external forces during use. This fixing method can effectively improve the structural stability of the angle adjustment mechanism 2, thereby providing reliable support for the multi-directional adjustment function of the desktop 1, ensuring the safety and stability of the entire device during use. The rear side of the display screen 3 is fixedly connected with a quick-release mechanism 4, and the two sides of the desktop 1 are fixedly connected with drive slide rails 7.

[0034] Specifically, during installation, multiple bolts 2701 are threaded into the base plate 21 to fix the components of the angle adjustment mechanism 2. Bolts 2702 are used to connect the connecting plate 2703 to the rear of the display screen 3. During use, when it is necessary to rotate the support table 1 horizontally, external force is applied to make the rotating connecting column 24 rotate in the bearing 23, which drives the rotating seat 22 to rotate horizontally. To adjust the tilt and left and right tilt angles of the display screen 3, the rotation angles of the first support arm 25 and the second support arm 26 in the hinge 28 are changed, and the included angle between the two is adjusted accordingly. If it is necessary to disassemble the display screen 3, the quick release mechanism 4 on the rear side can be operated to separate it. In addition, the drive slide rails 7 on both sides of the support table 1 can be used to make the display screen 3 slide on the support table 1 to meet different usage needs.

[0035] Referring to Figures 1 and 4, the quick-release mechanism 4 includes a sponge anti-slip layer 42. The sponge anti-slip layer 42 protects both sides of the supporting tabletop 1, preventing scratches and damage to the surface of the supporting tabletop 1 from hard collisions with components such as the fastening plate 41, thus maintaining its integrity and aesthetics. The sponge material also has a certain cushioning effect, absorbing some external force and further improving the safety of the supporting tabletop 1. The adjacent sides of the sponge anti-slip layer 42 are slidably connected to the outer sides of the display screen 3. Fastening plates 41 are fixedly connected to both sides of the sponge anti-slip layer 42. When installation is required... When disassembling the support tabletop 1, the electric telescopic rod 4301 is activated. The electric telescopic rod 4301 pushes the fastening plate 41 and the sponge anti-slip layer 42, thereby realizing the quick installation and disassembly of the support tabletop 1, which improves the installation and disassembly efficiency between the support tabletop 1 and the display screen 3. A power assembly 43 is fixedly connected to the adjacent side of the fastening plate 41. The power assembly 43 includes two electric telescopic rods 4301. The drive ends of the two electric telescopic rods 4301 are fixedly connected to the adjacent side of the fastening plate 41. A support limiting plate 4302 is fixedly connected to the bottom of the electric telescopic rod 4301.

[0036] Specifically, when using the quick-release mechanism 4 to install the support tabletop 1, the two electric telescopic rods 4301 in the power assembly 43 are activated. The drive ends of the electric telescopic rods 4301 extend, pushing the fastening plate 41 along with the sponge anti-slip layer 42 toward the support tabletop 1 until the sponge anti-slip layer 42 is tightly attached to both sides of the support tabletop 1, completing the installation and fixing. When it is necessary to disassemble the support tabletop 1, the electric telescopic rods 4301 are activated again, causing their drive ends to retract, moving the fastening plate 41 and the sponge anti-slip layer 42 away from the support tabletop 1, releasing the fixing constraint on the support tabletop 1, and the support tabletop 1 can be easily disassembled. The electric telescopic rods 4301 operate stably with the assistance of the bottom support limiting plate 4302, and drive the fastening plate 41 and the sponge anti-slip layer 42 through the telescopic action, completing the quick disassembly and assembly operation of the support tabletop 1.

[0037] The drive slide rail 7 has a support storage box 5 fixedly connected to one side of each other. When it is necessary to store the desktop support 1 and the display screen 3, the drive slide rail 7 is used to store the desktop support 1 and the display screen 3 into the support storage box 5. Then, the top cover 6 is rotated to cover the top of the support storage box 5. The top cover 6 is rotatably connected to the outside of the support storage box 5. After the top cover 6 covers the top of the support storage box 5, it can effectively prevent dust from entering the storage box, thereby avoiding dust from contaminating and damaging the surface and internal structure of the desktop support 1 and the display screen 3. The outside of the desktop support 1 is slidably connected to the inside of the support storage box 5, and the top inner side of the top cover 6 is slidably connected to the display screen 3. On the outer top side of screen 3, the two support limiting plates 4302 are fixedly connected to the outside of the connecting plate 2703 on their adjacent sides. The electric telescopic rod 4301 is fixedly connected to the outside of the connecting plate 2703 on its adjacent side. A light shield 44 is fixedly connected to the outer front side of screen 3. The light shield 44 can effectively block the interference of external light on screen 3, reduce reflection and glare. In strong light environment, users can still clearly see the content on screen 3, which improves the viewing comfort and visual effect. It is especially suitable for work scenarios that require long-term screen viewing. The outer left side of the two electric telescopic rods 4301 is fixedly connected to the outer rear side of screen 3.

[0038] Specifically, when the device is in operation, if it is necessary to store the support table 1 and the display screen 3, the drive slide rail 7 is activated, allowing the support table 1 and the display screen 3 to slide along the slide rail into the support storage boxes 5 on both sides. Then, the top cover 6 is rotated to cover the top of the support storage box 5, completing the storage. When in use, the top cover 6 is opened first, and the support table 1 and the display screen 3 are slid out of the support storage box 5 by driving the slide rail 7. The light shield 44 fixed to the front of the display screen 3 plays a role in blocking external light interference during use. In addition, the two electric telescopic rods 4301 are fixed on the connecting plate 2703 on their adjacent sides, and their outer left side is fixed to the rear of the display screen 3. When it is necessary to adjust the angle and position of the display screen 3, the electric telescopic rods 4301 are activated, driving the connecting plate 2703 and the display screen 3 to make corresponding adjustments. The two support limiting plates 4302 cooperate to fix the connecting plate 2703 to ensure the stability of the adjustment process.

[0039] The implementation principle of this application embodiment is as follows: First, the bearing 23 and the rotating connecting column 24 rotate, thereby driving the rotating seat 22 to rotate, realizing the horizontal rotation of the supporting tabletop 1. Through the different rotation angles of the first support arm 25 and the second support arm 26, the included angle is formed, thereby realizing the tilt and left and right tilt adjustment of the supporting tabletop 1. Thus, through the use of multi-stage hinge 28, a larger adjustment range and higher stability are provided, thereby enabling the LCD screen to be adjusted in multiple directions according to different situations, thus increasing flexibility.

[0040] Secondly, the support limiting plates 4302 on both sides of the rear connecting plate 2703 of the display screen 3 serve to support and limit the power component 43, thereby activating the electric telescopic rods 4301 on both sides to push the fastening plate 41 and the sponge anti-slip layer 42 to quickly install and remove the support tabletop 1. The sponge anti-slip layer 42 protects both sides of the support tabletop 1. The support storage box 5 has two drive slide rails 7 inside, which drive the support tabletop 1 and the display screen 3 into the support storage box 5. The top cover 6 is rotated to cover the top of the support storage box 5, thereby reducing the entry of dust when not in use. The use of the anti-light plate 44 makes the user's viewing clearer.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
