As shown in fig. 1, an embodiment of the present invention provides a liquid crystal display housing 100. As shown in fig. 2, the liquid crystal display housing 100 includes a back plate 110 and a connection column 120. The back plate 110 has a carrying surface for connecting with the lcd 210. One end of the connecting column 120 is connected to the surface of the back plate 110 away from the carrying surface, and as shown in fig. 3, a mounting hole 122 is formed on the end surface of the connecting column 120 away from the back plate 110. The back plate 110 is provided with a U-shaped connecting slot 130 penetrating through the back plate 110, and the U-shaped connecting slot 130 is wound around a portion of the periphery of the connecting column 120.

It will be appreciated that the liquid crystal display housing 100 serves to carry and protect the liquid crystal display 210. In some embodiments, the lcd panel 210 may be an IPS (In-Plane Switching) lcd panel.

It is understood that the lcd display housing 100 may be made of plastic or metal. In some embodiments, the liquid crystal display housing 100 may be ABS plastic or PC plastic, etc., which reduces the weight of the liquid crystal display housing 100 and the cost of the liquid crystal display housing 100.

Specifically, as shown in fig. 2, the liquid crystal display housing 100 includes a back plate 110, and it is understood that the back plate 110 has a flat plate-shaped structure. In some embodiments, the back plate 110 may be rectangular, circular, or polygonal, etc., to meet different requirements.

The back plate 110 has a bearing surface, which is understood to be a smooth surface. The lcd 210 is connected to the carrying surface of the back plate 110, so that the back plate 110 can support and protect the lcd 210.

In some embodiments, as shown in fig. 3, the liquid crystal display 210 includes a liquid crystal display body 212, a circuit board 214, and metal leads 216. As can be appreciated, the liquid crystal display body 212 is used to display a picture. The liquid crystal display body 212 is connected with the bearing surface of the back plate 110. The circuit board 214 is disposed on one side of the back plate 110 away from the carrying surface, the back plate 110 is provided with a first through hole, and the metal wire 216 passes through the first through hole to be connected with the liquid crystal display body 212 and the circuit board 214, so that the circuit board 214 can control the liquid crystal display body 212.

One end of the connecting column 120 is connected to the surface of the back plate 110 away from the carrying surface, and it can be understood that the connecting column 120 may be a cylinder, a cuboid, a prism, or the like. Specifically, the connection column 120 and the liquid crystal display screen 210 are respectively disposed at both sides of the rear plate 110, and the rear plate 110 can be connected with other components through the connection column 120.

In some embodiments, the number of the connection posts 120 may be one or more, and the shapes of the connection posts 120 may be the same or different, so as to meet different connection requirements, thereby improving the flexibility of the lcd housing 100.

In some embodiments, the connecting posts 120 can be fixedly connected to the surface of the back plate 110 away from the carrying surface, so as to improve the reliability of the connection between the connecting posts 120 and the back plate 110. In some embodiments, the connecting posts 120 can also be detachably connected to the surface of the back plate 110 away from the carrying surface, thereby improving the flexibility of the lcd display housing 100.

In some embodiments, the connecting posts 120 and the back plate 110 can be made of the same material or different materials.

As shown in fig. 4, the end surface of the connecting column 120 away from the back plate 110 is provided with a mounting hole 122, so that the back plate 110 can be connected with other components through the mounting hole 122, and the convenience of connection between the back plate 110 and other components is improved.

In some embodiments, the mounting hole 122 may be square, circular, polygonal, or the like. In some embodiments, when the number of the connecting columns 120 is multiple, the depth and the size of the mounting holes 122 formed on different connecting columns 120 may be the same or different. In some embodiments, the mounting holes 122 are threaded holes.

The back plate 110 is provided with a U-shaped connecting slot 130, and it can be understood that a circular arc-shaped curve may be connected with the straight line segments to form the U-shaped connecting slot 130, a plurality of straight line segments may be connected to form the U-shaped connecting slot 130, and an irregular curve may be used as the U-shaped connecting slot 130, so that the U-shaped connecting slot 130 can be wound around a portion of the periphery of the connecting column 120.

It is understood that the number of the U-shaped coupling grooves 130 is the same as the number of the coupling posts 120. In some embodiments, when the number of the U-shaped connecting slots 130 is plural, the shapes of the plural U-shaped connecting slots 130 may be the same or different.

Specifically, when the connecting posts 120 are connected to other components through the mounting holes 122, the back plate 110 is stressed in the thickness direction of the back plate 110 due to the flatness of the back plate 110, the height difference between the connecting posts 120, and the assembly tolerance between the mounting holes 122 and other components. Specifically, the stress may be directed along the back plate 110 to the lcd panel 210, or along the lcd panel 210 to the back plate 110. The backboard 110 deforms under the action of stress, so that the liquid crystal display screen 210 is stressed and extrudes liquid crystal in the liquid crystal display screen 210, the liquid crystal display screen 210 is subjected to light leakage, and the use reliability of the liquid crystal display screen shell 100 is reduced.

Therefore, the back plate 110 is provided with the U-shaped connecting slot 130, the U-shaped connecting slot 130 is disposed around a portion of the periphery of the connecting column 120, and the U-shaped connecting slot 130 penetrates through the back plate 110 along the thickness direction of the back plate 110, i.e., the depth of the U-shaped connecting slot 130 is the same as the thickness of the back plate 110. Specifically, as shown in fig. 5, the U-shaped coupling groove 130 can serve to separate the peripheral portion of the coupling post 120 from the rear plate 110. When the connection post 120 is connected to other components through the mounting hole 122, as shown in fig. 6, the portion of the back plate 110 connected to the connection post 120 can be bent upward under the action of stress, or as shown in fig. 7, the portion of the back plate 110 connected to the connection post 120 can be bent downward under the action of stress, so as to drive the connection post 120 to move along the thickness direction of the back plate 110, that is, along the direction from F1 to F2 in fig. 5, or along the direction from F2 to F1 in fig. 5, thereby counteracting the influence of stress on the back plate 110, preventing the stress from being transmitted to other positions of the back plate 110, avoiding the back plate 110 from being deformed greatly under the action of stress, reducing the extrusion of the back plate 110 on the liquid crystal in the liquid crystal display 210, avoiding the light leakage of the liquid crystal display 210, and improving the reliability of the use of the liquid crystal display housing 100.

It is understood that the thickness of the back plate 110 can affect the range of movement of the connecting posts 120 along the thickness of the back plate 110. The larger the thickness of the back plate 110 is, the smaller the moving range of the connecting column 120 along the thickness direction of the back plate 110 is, the smaller the thickness of the back plate 110 is, and the larger the moving range of the connecting column 120 along the thickness direction of the back plate 110 is. In some embodiments, the thickness of the back plate 110 may be between 2.2 mm and 2.5 mm, so as to control the displacement of the connecting column 120 along the thickness direction of the back plate 110, thereby preventing the connecting column 120 from moving due to too large thickness of the back plate 110, and reducing the counteracting effect on the stress, or the thickness of the back plate 110 is too small, which results in the strength reduction of the back plate 110, so that the connecting column 120 is broken relative to the back plate 110, and the like, and further improves the reliability of the use of the liquid crystal display housing 100. Specifically, the thickness of the back sheet 110 may be 2.25 millimeters, 2.3 millimeters, 2.4 millimeters, or the like.

It can be known from the foregoing, as shown in fig. 2, through setting up U type connecting groove 130, can play the effect of separating spliced pole 120 peripheral part and backplate 110, make spliced pole 120 can follow the removal of backplate 110 thickness direction (also be spliced pole 120 can follow the arrow direction removal in fig. 5), thereby offset the stress of backplate 110, stress can't transmit to backplate 110 through spliced pole 120, backplate 110 has been avoided taking place great deformation under the effect of stress, thereby the extrusion that backplate 110 led to the fact to liquid crystal in liquid crystal display 210 has been reduced, liquid crystal display 210 has been avoided appearing the light leak, the use reliability of liquid crystal display casing 100 has been improved.

Moreover, by arranging the connecting columns 120 and the mounting holes 122, the mounting between the back plate 110 and other parts is realized, the mounting convenience between the back plate 110 and other parts is improved, the detachable connection between the back plate 110 and other parts is realized, and the use convenience of the liquid crystal display shell 100 is improved.

Further, as shown in fig. 8, the U-shaped connecting slot 130 includes a connecting slot body 132, a first extending portion 142 and a second extending portion 144. The connecting groove body 132 is disposed around a portion of the periphery of the connecting column 120. The coupler slot body 132 includes a first end 134 and a second end 136, with the first end 134 and the second end 136 being spaced apart to form a coupler slot opening 138. As shown in fig. 9, one end of the first extending portion 142 is connected to the first end 134, and the other end of the first extending portion 142 extends away from the connecting groove body 132. One end of the second extending portion 144 is connected to the second end 136, and the other end of the second extending portion 144 extends away from the connecting groove body 132.

It is understood that the connecting slot body 132 may be C-shaped, square, triangular, irregular, etc. The connecting groove body 132 is wound around a portion of the periphery of the connecting column 120, so as to separate the peripheral portion of the connecting column 120 from the back plate 110, thereby preventing the back plate 110 from deforming greatly under stress.

Specifically, the coupler slot body 132 includes a first end 134 and a second end 136, as shown in FIG. 9, with the first end 134 and the second end 136 being spaced apart to form a coupler slot opening 138. It will be appreciated that the connecting stud 120 is connected to the back plate 110 through the connecting slot opening 138, so that the range of movement of the connecting stud 120 along the thickness direction of the back plate 110 can be controlled by controlling the size of the connecting slot opening 138.

It will be appreciated that the greater the distance between the first end 134 and the second end 136, i.e., the greater the connecting slot opening 138, the lesser the extent of movement of the connecting stud 120 in the thickness direction of the back plate 110. The smaller the distance between the first end 134 and the second end 136, i.e., the smaller the connecting slot opening 138, the greater the range of movement of the connecting stud 120 in the thickness direction of the back plate 110.

In some embodiments, the distance between the first end 134 and the second end 136 may be between 8 mm and 10 mm, so as to avoid the connection slot opening 138 being too large, which may result in too small a movement range of the connection post 120 along the thickness direction of the back plate 110, which may affect the counteracting effect of the connection post 120 on the stress, or the connection slot opening 138 being too small, which may result in a decrease in the connection strength between the connection post 120 and the back plate 110, which may cause the connection post 120 to break relative to the back plate 110, and so on. Specifically, the distance between the first end 134 and the second end 136 may be 8.5 millimeters, 9 millimeters, or 9.5 millimeters, among others.

It is understood that the first extension 142 and the second extension 144 may be straight segments or curved segments. One end of the first extension part 142 and one end of the second extension part 144 are respectively connected with the first end 134 and the second end 136, and the other end extends in a direction far away from the connecting groove body 132, so that the moving range of the connecting column 120 in the thickness direction of the back plate 110 can be further enlarged, the counteracting effect of the connecting column 120 on the stress is improved, and the use reliability of the liquid crystal display shell 100 is ensured.

It will be appreciated that the longer the lengths of the first and second extensions 142, 144, the greater the range of movement of the connection post 120 through the thickness of the back plate 110. The shorter the length of the first and second extensions 142 and 144, the smaller the range of movement of the connection post 120 along the thickness of the back plate 110. Therefore, by controlling the lengths of the first extension part 142 and the second extension part 144, the moving range of the connecting column 120 along the thickness direction of the back plate 110 can be controlled, and the use flexibility of the liquid crystal display housing 100 is further improved.

In some embodiments, the lengths of the first extension 142 and the second extension 144 may be the same or different.

In some embodiments, the lengths of the first extension 142 and the second extension 144 are between 5 mm and 6 mm, so as to avoid that the lengths of the first extension 142 and the second extension 144 are too short, which results in a reduced moving range of the connection column 120 along the thickness direction of the back plate 110 and affects the stress cancellation effect of the connection column 120, or that the lengths of the first extension 142 and the second extension 144 are too long, which results in a reduced connection strength between the connection column 120 and the back plate 110, which causes the connection column 120 to break relative to the back plate 110, and the like. Specifically, the first extension 142 and the second extension 144 may have a length of 5.3 millimeters, 5.5 millimeters, or 5.8 millimeters.

Further, as shown in fig. 9, the first extension portion 142 is parallel to the second extension portion 144.

It can be understood that the first extension portion 142 and the second extension portion 144 are straight line segments and are parallel, which can further increase the moving range of the connection column 120 along the thickness direction of the back plate 110, improve the effect of the connection column 120 on counteracting stress, and ensure the use performance of the liquid crystal display housing 100.

It is understood that the first extension 142 and the second extension 144 may be approximately parallel or completely parallel.

Further, as shown in fig. 8, the connecting slot body 132 is C-shaped, and the connecting slot opening 138 faces away from the edge of the back plate 110.

As can be understood, the connecting groove body 132 is C-shaped, so that the connecting groove body 132 can be wound around the peripheral portion of the connecting column 120, thereby improving the smoothness of the peripheral portion of the connecting column 120, preventing scratches between the peripheral portion of the connecting column 120 and other positions of the liquid crystal display housing 100, and improving the reliability of the use of the liquid crystal display housing 100.

In some embodiments, the distance between the connecting column 120 and the connecting groove body 132 may be between 7 mm and 8 mm, so as to avoid that the distance between the connecting column 120 and the connecting groove body 132 is too large, which results in a reduction of the moving range of the connecting column 120 along the thickness direction of the back plate 110, which affects the counteracting effect of the connecting column 120 on the stress, or that the distance between the connecting column 120 and the connecting groove body 132 is too small, which results in a reduction of the connecting strength between the connecting column 120 and the back plate 110. Specifically, the distance between the connecting post 120 and the connecting slot body 132 may be 7.2 mm, 7.5 mm, 7.8 mm, or the like.

Specifically, set up the edge of backplate 110 is kept away from to orientation of connecting groove opening 138, thereby can play the spaced effect to between the edge of backplate 110 and the spliced pole 120 peripheral part, avoid stress transfer to the edge of backplate 110, thereby avoided backplate 110 to take place great deformation under the effect of stress, the separation effect of U type connecting groove 130 to spliced pole 120 peripheral part and backplate 110 has been improved, liquid crystal display 210 atress has been avoided taking place the light leak, the use reliability of liquid crystal display casing 100 has been improved.

In some embodiments, when the number of the connecting columns 120 is plural, the opening orientations between different connecting slot bodies 132 may be the same or different.

Further, as shown in fig. 10, the liquid crystal display housing 100 further includes a rear cover 150 and a connector 162. As shown in fig. 11, the rear cover 150 is opened with a connection hole 152, and the connection hole 152 communicates with the mounting hole 122. The connecting member 162 is used to connect the connecting post 120 through the connecting hole 152 and the mounting hole 122.

In some embodiments, the material of the rear cover 150 may be the same as or different from the material of the back plate 110.

It can be understood that the rear cover 150 is connected to the connecting column 120 through the connecting member 162, so that the rear cover 150 can be connected to the rear panel 110, thereby protecting and supporting the rear panel 110, preventing the circuit board 214 and the metal wires 216 from being damaged, prolonging the service life of the rear panel 110, and improving the reliability of the lcd housing 100. In some embodiments, the mounting holes 122 are threaded holes and the connectors 162 are bolts.

Through setting up back lid 150, played the effect that the protection was supported to backplate 110, further improved the use reliability of liquid crystal display casing 100 to realize being connected between back lid 150 and backplate 110 through connecting piece 162, improved the convenience of being connected between back lid 150 and the backplate 110, simple structure reduces the cost of liquid crystal display casing 100 simultaneously.

In some embodiments, as shown in fig. 12, the liquid crystal display housing 100 further includes a fixing member 220, and the fixing member 220 is used to connect the liquid crystal display housing 100 with other components. The fixing member 220 is provided with a second through hole, and the connecting member 162 passes through the second through hole to be connected with the connecting post 120, so that the fixing member 220 can be fixed relative to the connecting post 120, and the use reliability of the liquid crystal display shell 100 is improved.

Further, as shown in fig. 13, the liquid crystal display housing 100 further includes a reinforcing glue 156. The reinforced glue 156 is filled in the U-shaped connecting groove 130.

As can be appreciated, the reinforcing glue 156 serves to increase the strength of the connection between the connecting post 120 and the back plate 110. Specifically, the reinforcing glue 156 may be filled in the U-shaped coupling groove 130 before the coupling post 120 is coupled to other components, and then the coupling between the coupling post 120 and other components may be performed. The curing of the reinforcing glue 156 requires a certain time, so that the connecting column 120 can move along the thickness direction of the back plate 110 before the reinforcing glue 156 is cured, and the stress is offset, so that the stress cannot be transmitted to the back plate 110. After the connecting column 120 offsets the stress, the reinforcing glue 156 is cured to reinforce and fix the connecting column 120 and the back plate 110, so that the connection strength between the connecting column 120 and the back plate 110 is improved, the connecting column 120 is prevented from being broken relative to the back plate 110, and the use reliability of the liquid crystal display shell 100 is further improved.

In some embodiments, the reinforcing glue 156 may be black glue, transparent glue, or the like, which ensures a reinforcing effect between the connection post 120 and the rear plate 110, thereby improving the reliability of the use of the lcd housing 100.

In some embodiments, the width of the U-shaped connecting groove 130 may be set to be between 2 mm and 3 mm, so as to avoid that the width of the U-shaped connecting groove 130 is too large, which causes the reinforcing glue 156 to flow out of the U-shaped connecting groove 130 before being uncured, which affects the connection effect between the connecting column 120 and the back plate 110, or that the width of the U-shaped connecting groove 130 is too small, which causes friction between the connecting column 120 and the back plate 110, which affects the counteracting effect of the connecting column 120 on the stress. Specifically, the width of the U-shaped connecting groove 130 may be 2.3 mm, 2.5 mm, 2.8 mm, or the like.

Further, as shown in fig. 14, the back plate 110 has a rectangular shape, the number of the connecting posts 120 is four, and the four connecting posts 120 are respectively disposed near four vertices of the rectangular shape.
