Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a wide-viewing-angle, high-color-gamut liquid crystal display screen. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat-panel display used in televisions and computers. Their advantages include low power consumption, small size, and low radiation. LCDs utilize a liquid crystal solution in two polarizing materials; when an electric current passes through the liquid, the crystals rearrange to achieve image formation. With the rapid development of display technology, wide-viewing-angle, high-color-gamut LCDs are becoming increasingly popular and are widely used in televisions, computer monitors, tablets, and automotive displays. These displays continuously innovate in structure and technology, striving to provide users with a superior visual experience.

[0003] However, in existing technologies, most wide-viewing-angle, high-color-gamut LCD screens are equipped with legs during actual use. These legs are generally either detachable or fixed. Detachable installation requires the legs to be assembled when needed and disassembled when not in use. In practice, they cannot be folded easily and require disassembly and assembly, which is cumbersome. Fixed installation, on the other hand, occupies a large amount of space when not in use. Therefore, this invention proposes a wide-viewing-angle, high-color-gamut LCD screen to solve the aforementioned problems. Utility Model Content

Receiving grooves are provided at the front and rear of the folding legs. Extension legs are rotatably mounted on the inner walls of the two receiving grooves via pins. Rubber pads are provided on the outer sides of the extension legs. An anti-rotation assembly is provided on the folding legs to prevent the extension legs from rotating after they are unfolded.

[0006] Preferably, the locking assembly includes a groove formed at the rear of the machine body, an inclined slider slidably mounted on the inner wall of the groove, a push-out spring fixed between the inclined slider and the groove, a lever fixed on the surface of the inclined slider, and a side baffle fixed at the rear of the machine body.

[0007] Preferably, the anti-rotation assembly includes a hollow box fixed to the surface of the folding leg, the end of the pin passes through the folding leg and extends into the hollow box, an anti-rotation ratchet is fixed to the surface of the pin, a limiting post that cooperates with the anti-rotation ratchet is slidably provided on the surface of the hollow box, a protrusion is fixed to the surface of the limiting post, and a locking spring is fixed between the protrusion and the hollow box.

[0008] Preferably, a limiting strip is fixed to the inner wall of the receiving groove, and the limiting strip is used to limit the extension leg.

[0009] Preferably, a magnetic plate is embedded in the inner wall of the receiving groove, and an iron sheet that works in conjunction with the magnetic plate is fixed to the inner side of the extended leg.

[0010] Preferably, a reset torsion spring is fitted on the surface of the rotating shaft, with one end of the reset torsion spring fixed to the machine body and the other end fixed to the folding support leg. Beneficial effects

[0011] This invention provides a wide-viewing-angle, high-color-gamut liquid crystal display screen. Compared with the prior art, it has the following advantages:

[0012] This wide-viewing-angle, high-color-gamut LCD screen, through the cooperation of the inclined slider and the side baffle, achieves synchronous limiting of both sides of the folding legs.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-8 The present invention provides the following technical solution: a wide-viewing-angle, high-color-gamut liquid crystal display screen, including a body 1 and a display panel 2 embedded in the front side wall of the body 1. Folding legs 4 are rotatably mounted on both sides of the rear of the body 1 via pivots 3. A locking component 5 is provided at the rear of the body 1 to limit the two sides of the folding legs 4. Receiving grooves 6 are provided at the front and rear of the folding legs 4. Extension legs 8 are rotatably mounted on the inner walls of the two receiving grooves 6 via pins 7. Rubber pads 10 are provided on the outer side of the extension legs 8. An anti-rotation component 9 is provided on the folding legs 4 to prevent the extension legs 8 from rotating after they are unfolded.

[0024] The receiving groove 6 is used to accommodate the extension leg 8, so that the extension leg 8 can be folded and stored. A magnetic plate 12 is embedded in the inner wall of the receiving groove 6, and an iron plate 13 that works with the magnetic plate 12 is fixed on the inner side of the extension leg 8. The magnetic plate 12 and the iron plate 13 can be used to position the extension leg 8 and prevent the extension leg 8 from rotating outside the receiving groove 6 after folding. When the extension leg 8 is unfolded, the bottom height of the rubber pad 10 is lower than that of the folded leg 4. When providing support, the design of the rubber pad 10 can increase friction and improve the stability during use.

[0025] In this embodiment, the locking component 5 includes a groove 51 formed at the rear of the body 1, an inclined slider 52 is slidably mounted on the inner wall of the groove 51, an ejector spring 53 is fixed between the inclined slider 52 and the groove 51, a lever 54 is fixed on the surface of the inclined slider 52, and a side baffle 55 is also fixed at the rear of the body 1.

[0026] The inclined slider 52 has an inclined surface design on the side near the folding leg 4. When the folding leg 4 rotates downward, it can smoothly press the inclined surface of the inclined slider 52. Under the action and reaction forces, the downward component of the force along the inclined slider 52 will push the entire inclined slider 52 to slide into the groove 51. The slope of the inclined slider 52 is set to ensure that the folding leg 4 can smoothly push the inclined slider 52 to slide into the groove 51 when it rotates. Until the folding leg 4 continues to rotate and is blocked by the side baffle 55, at this time, under the elastic force of the ejector spring 53, the inclined slider 52 is driven to slide quickly out of the groove 51, realizing the limitation on the other side of the folding leg 4. Through the cooperation of the inclined slider 52 and the side baffle 55, the simultaneous limitation on both sides of the folding leg 4 is achieved.

[0027] In this embodiment, the anti-rotation component 9 includes a hollow box 91 fixed to the surface of the folding leg 4. The end of the pin 7 passes through the folding leg 4 and extends into the hollow box 91. An anti-rotation ratchet 92 is fixed to the surface of the pin 7. A limiting post 93 that cooperates with the anti-rotation ratchet 92 is slidably provided on the surface of the hollow box 91. A protrusion 94 is fixed to the surface of the limiting post 93. A locking spring 95 is fixed between the protrusion 94 and the hollow box 91.

[0028] The anti-rotation ratchet 92 design allows the extension leg 8 to rotate outward in one direction only from the receiving groove 6, thus preventing it from folding back after it is fully extended, thereby ensuring the stability of the extension leg 8 when it is extended and in use. The locking spring 95 facilitates the quick reset of the limit post 93. One side of the limit post 93 is designed with a slope, which restricts the anti-rotation ratchet 92 to rotate only in one direction.

[0029] In this embodiment, a limiting strip 11 is fixed to the inner wall of the receiving groove 6. The limiting strip 11 is used to limit the extension leg 8. After being limited by the limiting strip 11, the extension leg 8 can be horizontally extended and stabilized in conjunction with the rubber pad 10.

[0030] In this embodiment, a reset torsion spring 14 is sleeved on the surface of the rotating shaft 3. One end of the reset torsion spring 14 is fixed to the body 1, and the other end is fixed to the folding leg 4. The reset torsion spring 14 facilitates the folding leg 4 to quickly rotate back to its original position. A limiting block is provided at the rear of the body 1 to limit the upper part of the folding leg 4 and prevent the folding leg 4 from rotating too much. This block is not shown in the attached drawings.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] When in use, if the support leg needs to be unfolded, rotate the folding support leg 4 downwards. This will press against the inclined surface of the inclined slider 52. Under the action and reaction forces, the downward component of the force along the inclined slider 52 will push the entire inclined slider 52 into the groove 51 until the folding support leg 4 continues to rotate and is blocked by the side baffle 55. At this point, under the elastic force of the ejector spring 53, the inclined slider 52 will quickly slide out of the groove 51, thus limiting the other side of the folding support leg 4. In conjunction with the side baffle 55, the folding leg 4 is limited on both sides. At this time, the folding leg 4 is in a vertical position. Then, the extension leg 8 is forcefully pried open, causing the magnetic plate 12 to separate from the iron plate 13. The extension leg 8 rotates outward from the receiving groove 6. After the extension leg 8 is fully extended, the extension leg 8 is blocked and limited by the limiting strip 11. At the same time, the anti-rotation ratchet 92 cooperates with the limiting post 93 to prevent the extension leg 8 from folding and rotating, so that the entire leg can achieve stable support.

[0033] When folding is required, pull out the protrusion 94 to separate the limiting post 93 from the anti-rotation ratchet 92. At this time, the extension leg 8 can be rotated in the opposite direction to fold until the magnetic plate 12 and the iron plate 13 come into contact and are attracted to each other to position the extension leg 8. Then, push the inclined slider 52 into the groove 51 through the lever 54 so that the inclined slider 52 loses its limiting position on the folding leg 4. Under the torque of the reset torsion spring 14, the entire folding leg 4 is rotated back to reset, thereby realizing the entire folding operation.
