Description

Technical Field

[0001] This utility model is an anti-collision LCD screen, belonging to the field of LCD screens. Background Technology

[0002] An LCD screen is constructed by placing liquid crystals between two parallel glass plates. Between the two glass plates are many fine vertical and horizontal wires. By controlling whether or not electricity is applied, the rod-shaped crystal molecules change direction, refracting light to produce an image. The basic principle of the screen's display is to fill the space between the two parallel plates with liquid crystal material. By using voltage to change the arrangement of the molecules inside the liquid crystal material, the purpose of blocking and transmitting light is achieved, thus displaying images of varying shades and staggered patterns. Moreover, by adding a three-primary-color filter layer between the two plates, color images can be displayed.

[0003] Existing LCD screens are relatively fragile and lack external protective structures, leaving them exposed. When external objects collide with the LCD screen, the impact force is relatively large, which can easily damage the surface of the LCD screen, causing it to crack and break. This reduces the lifespan of the LCD screen and increases the financial burden on users. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-collision LCD screen.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A collision-resistant LCD screen includes a protective housing for the LCD screen. An LCD screen is disposed inside the protective housing. A collision-resistant mechanism is provided on the outer surface of the protective housing, located outside the LCD screen. The collision-resistant mechanism includes a collision-resistant frame, which is fixed to the outer surface of the protective housing. A receiving groove is formed on the upper and lower inner walls of the collision-resistant frame, and a folding baffle is disposed within each receiving groove. A guide groove is vertically formed on the left and right inner walls of the collision-resistant frame, cooperating with the folding baffle. The upper and lower ends of the guide groove are respectively connected to the two receiving grooves. The upper and lower folding baffles are connected and fixed together by a locking mechanism.

[0006] Furthermore, the folding baffle includes several protective plates that are hinged together end to end. Several of the protective plates are stacked inside the receiving groove. Each of the protective plates has a guide slide shaft at both ends. The guide slide shaft is slidably connected in the guide slide groove. The guide slide shaft on the protective plate away from the opening of the receiving groove is rotatably connected to the inner wall of the receiving groove.

[0007] Furthermore, magnets are provided at the hinge points of two adjacent protective plates, and the magnets on the two protective plates are magnetically attracted together.

[0008] Furthermore, the locking mechanism includes a groove formed on the bottom folding baffle, a locking plate is hinged to one side of the groove via a pivot, and a locking block is provided at the center of the other side of the locking plate.

[0009] Furthermore, the locking mechanism also includes a mating groove on the top folding baffle, the mating groove having an arc-shaped groove that mates with the snap-fit ​​block, and the end of the arc-shaped groove having a snap-fit ​​groove.

[0010] Furthermore, a damping block and a damping washer are respectively provided on the inner wall of the snap-fit ​​groove and the outer surface of the snap-fit ​​block, and the damping block and the damping washer are snap-fitted and adapted together.

[0011] Furthermore, the inner wall of the guide groove is provided with a damping strip that cooperates with the guide shaft, and the vertical outer surface of the damping strip is provided with a plurality of damping protrusions.

[0012] The beneficial effects of this utility model are: The folding baffle design allows for stacking and storage in the receiving slot on the inner wall of the anti-collision frame when not in use. It will not protrude from the anti-collision frame and thus avoid affecting the normal viewing of the LCD screen. When the LCD screen is not in use and protection is needed, the protective plate located at the opening of the receiving slot is snapped open, and then the protective plate is pulled to unfold. During the unfolding process, the guide shafts on the side will slide vertically in the guide groove in sequence, so that several protective plates can be evenly unfolded to form a vertical plate to provide external protection for the LCD screen.

[0013] The design incorporates magnets, which provide vertical support to the unfolded folding panel through magnetic attraction, thereby improving its stability.

[0014] Through the design of the locking mechanism, after the upper and lower folding baffles are unfolded and joined together, the docking groove on the upper folding baffle and the groove on the lower folding baffle are joined together. Then, the snap-fit ​​plate is snapped to rotate from the groove into the docking groove. During this process, the snap-fit ​​block at the end of the snap-fit ​​plate will rotate along the arc groove in the docking groove. During the rotation of the snap-fit ​​block, the damping snap-fit ​​block at its end will be compressed. When the snap-fit ​​block rotates to the position of the snap-fit ​​groove, the damping snap-fit ​​block at the end of the snap-fit ​​block will elastically reset and then engage with the damping washer on the inner wall of the snap-fit ​​groove. This connects the upper and lower folding baffles into a whole to shield and protect the LCD screen, preventing the LCD screen from being damaged by external objects when it is not in use.

[0020] See Figure 3 , Figure 6 , Figure 7 The folding baffle includes several protective plates 6 hinged together end to end. These protective plates 6 are stacked inside the receiving groove 5. Each protective plate 6 has a guide shaft 14 at both ends, which is slidably connected to a guide groove 15. The guide shaft 14 on the protective plate 6 away from the opening of the receiving groove 5 is rotatably connected to the inner wall of the receiving groove 5. Through the design of the folding baffle, when not in use, it can be stacked and stored in the receiving groove 5 on the inner wall of the anti-collision frame 4, without protruding from the anti-collision frame 4 to avoid affecting the normal viewing of the LCD screen 2. When the LCD screen is not in use and protection is required... When the protective plate 6 located at the opening of the receiving groove 5 is pulled, the protective plate 6 is unfolded. During the unfolding process, the guide shaft 14 on the side of the protective plate 6 will slide vertically in the guide groove 15 in sequence, so that several protective plates 6 can be evenly unfolded to form a vertical plate to provide external protection for the LCD screen 2. Magnets 16 are provided at the hinge of two adjacent protective plates 6, and the magnets 16 on the two protective plates 6 are magnetically attracted together. Through the design of the magnets 16, when the folding baffle is unfolded, the attraction of the magnets 16 provides vertical support for the unfolded folding baffle, thereby improving the stability of the folding baffle after unfolding.

[0021] See Figures 3-5The locking mechanism includes a groove 7 formed on the bottom folding baffle. A locking plate 8 is hinged to one side of the groove 7 via a pivot 9. A locking block 10 is located at the center of the other side of the locking plate 8. The locking mechanism also includes a mating groove 11 on the top folding baffle.

A damping block and a damping washer are respectively provided on the inner wall of the locking groove 13 and the outer surface of the locking block 10. The damping block and the damping washer are locked together. Through the design of the locking mechanism, after the upper and lower folding baffles are unfolded and mated together, the upper folding baffle... The mating groove 11 on the stacked baffle and the groove 7 on the lower folding baffle are mated together. Then, the snap-fit ​​plate 8 is snapped to rotate from the groove 6 into the mating groove 11. During this process, the snap-fit ​​block 10 at the end of the snap-fit ​​plate 8 will rotate along the arc groove 12 in the mating groove 11. During the rotation, the damping snap-fit ​​block at the end of the snap-fit ​​block 10 will be compressed. When the snap-fit ​​block 10 rotates to the snap-fit ​​groove 13, the damping snap-fit ​​block at the end of the snap-fit ​​block 10 will elastically reset and engage with the damping washer on the inner wall of the snap-fit ​​groove 13.

[0023] When not in use, the protective plates can be stacked and stored in the receiving slots 5 on the inner wall of the anti-collision frame 4 without protruding from the anti-collision frame 4 to avoid affecting the normal viewing of the LCD screen 2. When the LCD screen is not in use and protection is needed, the protective plate 6 located at the opening of the receiving slot 5 is pressed, and then the protective plate 6 is pulled to unfold it. During the unfolding process, the guide shafts 14 on the side of the protective plate 6 will slide vertically in the guide grooves 15 in sequence, so that several protective plates 6 can be evenly unfolded to form a vertical plate to provide external protection for the LCD screen 2. After the upper and lower folding baffles are unfolded and connected, the connecting slots 11 on the upper folding baffle and the lower... The grooves 7 on the folding baffle are aligned. Then, the snap-fit ​​plate 8 is activated to rotate it from the groove 6 into the mating groove 11. During this process, the snap-fit ​​block 10 at the end of the snap-fit ​​plate 8 will rotate along the arc groove 12 within the mating groove 11. During the rotation, the damping snap-fit ​​block at the end of the snap-fit ​​block 10 will be compressed. When the snap-fit ​​block 10 rotates to the position of the snap-fit ​​groove 13, the damping snap-fit ​​block at the end of the snap-fit ​​block 10 will elastically reset and engage with the damping washer on the inner wall of the snap-fit ​​groove 13. This connects the folding baffles on the upper and lower sides into a whole to shield and protect the LCD screen 2, preventing the LCD screen 2 from being damaged by external objects when not in use.
