Description

Technical Field

[0001] The utility model relates to the field of liquid crystal display screens, in particular to a liquid crystal display screen with a multi-stage shock absorption function. Background Art

[0002] Liquid crystal display (LCD) is a technology that uses liquid crystal as an image display medium. Its working principle is to adjust the passage of light by controlling the orientation of liquid crystal molecules to form an image. LCD screens with multi-level vibration reduction function are designed to reduce the impact of vibration and impact on the screen, thereby protecting the display and extending its service life.

[0003] A search revealed that Chinese patent publication number CN216927950U discloses a liquid crystal display with a shock-absorbing function, comprising a liquid crystal display body, with hidden grooves formed on each of the four sides of the liquid crystal display body, each of which is elastically connected to a top plate. The advantage of this utility model is that when the liquid crystal display body needs to be moved after being packed, the shock-absorbing components on the four sides of the liquid crystal display body can be opened in advance, thereby preventing damage to internal components of the liquid crystal display body when it is shaken. When the liquid crystal display body is installed in a designated location, the shock-absorbing components on the four sides of the liquid crystal display body can be stored and hidden. This not only does not affect the aesthetics of the liquid crystal display body, but also allows the shock-absorbing components to be hidden, facilitating installation.

[0004] Although the above device can hide the shock-absorbing component when not in use by arranging the mutual cooperation between the card plate, the top plate and the hidden groove, the shock-absorbing component has a certain volume. Even if it is hidden, it will still cause the border width of the display screen to increase, thereby affecting the aesthetics of the display screen and is not practical enough. Therefore, a liquid crystal display screen with a multi-level shock-absorbing function is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a liquid crystal display screen with a multi-stage shock absorption function, including a display screen body 1, which is a liquid crystal display screen. Multi-stage buffering mechanisms 2 are provided on the upper, lower, left and right sides of the display screen body 1, which are used for buffering protection of the liquid crystal display screen during transportation and movement, and also reduce the possibility of damage to the display screen due to vibration. A limiting component 3 is commonly provided between the four multi-stage buffering mechanisms 2, and the number is four, which is used for connection and limiting between two multi-stage buffering mechanisms 2.

[0039] like Figure 6 - Figure 7 As shown, the limiting assembly 3 includes a shell 32, which is used to cooperate with the various components to connect. The front part of the shell 32 is provided with a cover plate 31, which is used to cooperate with the shell 32 to connect and fix multiple multi-stage buffer mechanisms 2. The rear side of the cover plate 31 is provided with a connector 34, which is used to cooperate with the connection and fixation between the cover plate 31 and the shell 32. The rear side of the cover plate 31 and the inner wall of the shell 32 are fixedly connected with positioning blocks 33, and the number is multiple, which is used to cooperate with further limiting the protective shell 21. The middle part of the shell 32 is provided with a connecting cavity 321, and the number is multiple, which is used to cooperate with the connection of the connector 34. The connector 34 includes a connecting The strips 341 are multiple in number and have a certain elasticity and can produce a certain degree of deformation. The front ends of the multiple connecting strips 341 are fixedly connected to the cover plate 31, and the connecting strips 341 are movably connected to the connecting cavity 321. The rear ends of the multiple connecting strips 341 are fixedly connected with a card block 342, and its shape is larger at the front and smaller at the back, which is convenient for the multiple card blocks 342 to enter the connecting cavity 321 and for the multiple card blocks 342 to be stuck on the rear side of the connecting cavity 321, thereby fixing the cover plate 31 and the shell 32. The outer front part of the card block 342 is provided with an arc surface 343, which makes it easier for the card block 342 to detach from the connecting cavity 321 when the cover plate 31 and the shell 32 are disassembled.

[0040] See also Figure 4 - Figure 5The multi-stage buffer mechanism 2 includes a protective shell 21, which is used to cooperate with the connection of various components. The interior of the protective shell 21 is fixedly connected with a shock-absorbing pad 22, which can be sleeved on the outside of the display body 1. It can be made of a relatively soft material such as rubber. Both ends of the protective shell 21 and the shock-absorbing pad 22 are set as inclined surfaces to facilitate the docking between the two multi-stage buffer mechanisms 2 and the connection and limitation of the limit assembly 3 to multiple multi-stage buffer mechanisms 2. The multi-stage buffer mechanism 2 also includes two buffer plates 23, which are used to cooperate with the display screen and the packaging box or the ground when it is impacted. Open to protect the display screen body 1, the two buffer plates 23 are fixedly connected to the side close to the protective shell 21 with a shock-absorbing spring 24, which is used to cooperate with the buffer plate 23 to provide buffering protection for the display screen, and multiple shock-absorbing springs 24 are fixedly connected to the protective shell 21. The front and rear sides of the protective shell 21 are provided with positioning holes 211, and there are multiple positioning holes. The positioning block 33 is movably connected to the positioning hole 211, which is used to cooperate with the connection and fixation of the limit assembly 3. The interior of the shock-absorbing pad 22 is provided with a buffer cavity 221, and there are multiple buffer cavities, which are used to improve the buffering effect of the shock-absorbing pad 22.

[0041] Working principle: When using, when the LCD screen needs to be buffered and protected, first install multiple protective shells 21 on the corresponding edges of the display screen body 1 according to their lengths, so that the shock-absorbing pads 22 are sleeved on the outside of the display screen body 1. When installing multiple multi-stage buffering mechanisms 2, it is necessary to ensure that the oblique surfaces of the protective shells 21 and the shock-absorbing pads 22 between the two multi-stage buffering mechanisms 2 are butted together. When the multiple multi-stage buffering mechanisms 2 completely wrap the sides of the display screen body 1, the outer shell 32 can be sleeved on the outside of the butt ends of the two multi-stage buffering mechanisms 2, so that the positioning blocks 33 in the outer shell 32 are respectively inserted into the positioning holes 211 on the two protective shells 21, and then the multiple connecting pieces 34 on the rear of the cover plate 31 are aligned with the outer shell 32. The plurality of connecting cavities 321 are then pushed backwards to insert the plurality of card blocks 342 into the connecting cavity 321 and move in the connecting cavity 321. When the plurality of card blocks 342 enter the connecting cavity 321, the connecting cavity 321 will make the plurality of card blocks 342 slightly closer to each other, and the plurality of connecting strips 341 will be deformed. When the plurality of card blocks 342 move to the rear end of the connecting cavity 321 and completely leave the connecting cavity 321, the plurality of card blocks 342 will lose the force applied by the connecting cavity 321, and the connecting strip 341 will be reset, thereby opening the plurality of card blocks 342, so that the plurality of card blocks 342 are stuck in the rear side of the connecting cavity 321. At this time, the positioning block 33 on the cover plate 31 will be stuck in the positioning port 211 at the front of the protective shell 21.

[0042] When subjected to vibration, the buffer plate 23 will be subjected to a certain force, and the buffer plate 23 will squeeze the shock-absorbing spring 24. At this time, the shock-absorbing spring 24 will react on the buffer plate 23, pushing the buffer plate 23 to reset, thereby converting the force exerted on the display screen to buffer the display screen.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
