Example 1
The embodiment provides a box, a display module and a display device. Wherein, the box participates in and constitutes the display module assembly, and a plurality of display module assemblies splice jointly into a display device. Therefore, in order to more clearly explain the technical features and beneficial effects of the case in this embodiment, the display module and the display device using the case are described as an example.
Referring to fig. 1, the display device provided in this embodiment includes a plurality of display modules 300, and the peripheral sides of the plurality of display modules 300 are spliced together to form a display surface.
Referring to fig. 2 and 3 in combination, the display module 300 includes a case 100, a display panel module 200 mounted on a front mounting surface 110 of the case 100, and a power and control module (not shown) mounted on a rear mounting surface of the case 100. Wherein, the display panel module 200 includes a plurality of RBG light sources arranged in a matrix; the power and control module is connected to an external power source, and then supplies power to the display panel 200 and provides control signals. In the present embodiment, the display device is exemplified as a planar display, and in other embodiments, a curved display, a slant display, or the like may be used.
Referring to fig. 4, the display device provided in this embodiment can be assembled and disassembled from the display module 300 at the middle position, so as to achieve the effect of front and rear maintenance. The display module 300 at the middle position is disassembled, and specifically, the structure of the case is changed. The specific steps are as follows:
the case 100 includes: a front mounting surface 110 for mounting the display panel module 200, and a peripheral side surface (not labeled) provided on a rear side of the front mounting surface 110 and provided around the front mounting surface 110. However, in the present embodiment, the box 100 is generally rectangular, and of course, in other embodiments, the box may have other shapes, such as a cake shape, an hourglass shape, or other shapes.
The peripheral side surface is uniformly provided with a first area (not marked) and a second area (not marked) along the circumferential direction. The first area and the second area may have distinct boundaries, for example, the first area is an upper side and a left side, and the second area is a lower side and a right side, so that the corner is a distinct boundary. Of course, there may be no distinct demarcations, for example, a first area comprising a portion of the upper and lower sides and all of the left sides, and a second area comprising a portion of the lower and upper sides and all of the right sides. Alternatively, the first region is disposed only on the left side and the second region is disposed only on the right side.
The first region is convexly provided with a plurality of first connection structures 160; referring to fig. 5, 6 and 7 in combination, the rear side of the first connecting structure 160 is cooperatively connected with the front side of the second connecting structure 170 of the other case 100. Wherein the first connection structure 160 is disposed entirely within the first region.
The second area is provided with a plurality of second connection structures 170 corresponding to the plurality of first connection structures 160 in a protruding manner, please refer to fig. 8 and fig. 9 in combination, wherein a front side surface of each second connection structure 170 is disposed corresponding to a rear side surface of the corresponding first connection structure 160; the front side of the second connection structure 170 is cooperatively connected with the rear side of the first connection structure 160 of the other case 100. Wherein the second connection structure 170 is disposed entirely within the second region. And is provided in correspondence with the first connection structure 160. The front side of the second connection structure 170 and the rear side of the first connection structure 160 are correspondingly disposed in this embodiment, which means that: the front side surface and the rear side surface are arranged in a coplanar manner, so that the front side surface and the rear side surface are directly connected with each other; or in an aligned arrangement, indirectly via an intermediate addition of shims or the like. Wherein coplanarity is a state including a tight thread joint, and a normal manufacturing assembly state with a clearance or error of several tens/hundreds of threads.
The first connection structure 160 and the second connection structure 170 may be a snap connection, a screw connection, a latch connection, or the like. Thereby achieving the effect of detachable connection. Since the rear side of the first connection structure 160 serves as a mating surface at the time of assembly, the first connection structure 160 cannot move backward but can move forward at the time of disassembly. And the front side of the second connection structure 170 serves as a mating surface, so that the second connection structure 170 cannot move forward but can move backward when detached. Further, since the first and second connection structures 160 and 170 are distributed in the first and second regions of the case 100. So as to be rotatable about a midline between the first and second regions as shown in figure 4. Further, the case 100 positioned in the middle of the display device can be rotated and then taken out, thereby achieving the effect of being capable of performing front and rear maintenance.
Therefore, in the display device provided in this embodiment, a first area and a second area are uniformly disposed along the circumferential direction through the peripheral side surface of the case 100. And the first region is convexly provided with a plurality of first connection structures 160; the second region is protruded with a plurality of second connection structures 170 corresponding to the plurality of first connection structures 160. Wherein the connection mating surfaces of the first connection structure 160 and the second connection structure 170 are opposite. Thus, the casing 100 positioned in the middle of the display device can be rotated and taken out, thereby achieving the effect of being capable of front and rear maintenance.
Further, in this embodiment, the case 100 has a rectangular parallelepiped structure. The peripheral sides include an upper side 120, a lower side 130, a left side 140, and a right side 150.
The first and second regions are disposed in a side-by-side arrangement about an axis 180 passing through the center of the front mounting face 110. The axis 180 passes through the center of the front mounting face 110 such that the peripheral sides have equal areas on either side of the axis 180. And thus can facilitate the rotation of the case 100 at the time of disassembly, and reduce interference with other cases at the time of rotation. It will be appreciated that the axis 180 is virtual and does not exist physically.
In this embodiment, the axis 180 passes through a pair of corners. Referring to fig. 3, the diagonal corners are the upper right corner and the lower left corner. So that the upper side 120 and the left side 140 are the first areas and the lower side 130 and the right side 150 are the second areas.
Of course, in other embodiments, it may also be:
the axis 180 passes through the upper side 120 and the lower side 130, or alternatively,
the axis 180 passes through the left side 140 and the right side 150, or alternatively.
For example, axis 180 passes through an intermediate location of upper side 120 and lower side 130; or axis 180 passes through the middle of upper side 120 to the right 1/2, axis 180 will pass through the middle of lower side 130 to the left 1/2. Correspondingly, two sides of the axis are respectively a first area and a second area, and a first connecting structure 160 and a second connecting structure 170 are respectively arranged in the first area.
Further, in the present embodiment, the first and second connection structures 160 and 170 include protruding connection plates, and mounting holes penetrating front and rear sides of the connection plates; the first connection structure 160 and the second connection structure 170 are fixed by screw-coupling.
In this embodiment, the first connection structure 160 and the second connection structure 170 are provided as protruding connection plates, which has the advantages of simple structure and convenient manufacture. In the present embodiment, the first connection structure 160 and the second connection structure are integrated on the case 100, so that it is possible to have high manufacturing accuracy.
Further, the mounting holes of the connection plates are aligned with the edges of the parts of the display panel modules 200 extending out of the case 100, so that after the plurality of cases 100 are spliced, the adjacent display panel modules 200 can be seamlessly abutted.
Specifically, the first connection structure 160 is disposed on the upper side 120 and the left side 140; the second connection structure 170 is disposed on the lower side 130 and the right side 150. Thus, when an assembler needs to maintain one display module 300, he removes his or her fixed screw and then drives the display module 300 to rotate clockwise, thereby turning back and forth to facilitate disassembly and maintenance.
Specifically, the upper side 120 is convexly provided with a plurality of upper connection plates, and specifically includes an upper connection plate 12, an upper connection plate 121, an upper connection plate 122, an upper connection plate 123, and an upper connection plate 124. The upper connecting plate is provided with mounting holes (not marked) penetrating through the front side and the rear side of the upper connecting plate; the mounting hole is used for allowing a bolt to pass through so as to be screwed and fixed.
The left side surface 140 is convexly provided with a plurality of left connecting plates, and specifically comprises a left connecting plate 141, a left connecting plate 142, a left connecting plate 143 and a left connecting plate 144, and the left connecting plate is provided with mounting holes (not labeled) penetrating through the front side and the rear side of the left connecting plate; the mounting hole is used for allowing a bolt to pass through so as to be screwed and fixed.
The upper and left connection plates constitute the first connection structure 160.
The lower side 130 is provided with a plurality of lower connecting plates in a protruding mode, and specifically comprises a lower connecting plate 131, a lower connecting plate 132, a lower connecting plate 133 and a lower connecting plate 134, and mounting holes penetrating through the front side and the rear side of the lower connecting plate are formed in the lower connecting plate; the mounting hole is used for allowing a bolt to pass through so as to be screwed and fixed.
The right side surface 150 is convexly provided with a plurality of right connecting plates 151, 152, 153 and 154, and the right connecting plates are provided with mounting holes penetrating through the front and rear sides of the right connecting plates; the mounting hole is used for allowing a bolt to pass through so as to be screwed and fixed.
The lower and right connection plates constitute the second connection structure 170.
In the present embodiment, by providing a plurality of connection plates on each side of the case 100, the connection strength with other cases 100 can be enhanced.
Further, in this embodiment, the plurality of connection plates located on the same side are arranged in a staggered manner in the front-rear direction. For example: referring to fig. 6, the upper connection plates 121 and 124 on the upper side 110 are located at one height, and the upper connection plates 122 and 123 are located at another height. For another example: referring to fig. 7, the left connection plates 141 and 143 on the left side 140 are located at one height, and the left connection plate 142 is located at another height.
In this embodiment, by setting the plurality of connection plates on the same side to be staggered, on one hand, the situation that stress on the same side of the box body 100 is concentrated after casting can be avoided; on the other hand, when the connecting plates on the same side are connected with the connecting plates of other box bodies 100, the stress is more dispersed, so that the frame of the box body 100 can be firmer and more stable.
Further, in this embodiment, the plurality of connection plates on one side are respectively staggered with the plurality of connection plates on the opposite side in the front-rear direction. For example: referring to fig. 6, the upper connection plate 121 on the upper side 110 and the lower connection plate 131 on the corresponding lower side are disposed in a staggered manner. For another example: referring to fig. 7, the left connecting plate 141 on the left side 140 is offset from the right connecting plate 151 on the right side 150.
In this embodiment, a pair of connecting plates on opposite sides are arranged in a staggered manner, so that the two connecting plates can be conveniently connected through bolts after being aligned front and back. And after connection, the display panel modules 200 can lie in the same plane.
Of course, in other embodiments, the pair of connection plates on opposite sides may be disposed in the same plane or in different planes, but not yet completely offset. And then the connection and fixing functions are realized through a direct connection scheme or other connecting pieces. After direct connection, the display screen can be spliced into a curved surface or an inclined surface; the display screen can be spliced into a plane, a curved surface or an inclined plane through other connecting pieces to realize connection.
Further, please refer to fig. 6 to 9 in combination, the front mounting surface 110 is divided into a plurality of layers in a rearward direction;
at least two connecting plates positioned on one side are arranged on different layers.
The layer of the plurality of connecting plates positioned at one side and the layer of the plurality of connecting plates positioned at the back side are arranged in different layers. For example, one side is provided at layers 1 and 2, and the other side is provided at layers 3 and 4; or,
one side is arranged on the 1 layer and the 3 layers, and the other side is arranged on the 2 layers and the 4 layers; still alternatively, or in addition to the above,
one side is arranged on the 1 layer and the 4 layers, and the other side is arranged on the 2 layers and the 3 layers; still alternatively, or in addition to the above,
one side is arranged on the 1 layer and the 4 layers, and the other side is arranged on the 2 layers and the 5 layers; layer 3 is left empty, etc.
Specifically, in this embodiment:
divided into four layers in a backward direction from the front mounting surface 110; the connecting plates at one side are arranged at two layers at intervals, and the connecting plates at the back side are arranged at the other two layers at intervals. Wherein the Z-axis direction is from front to back in the figure. Referring to fig. 6, the upper connection plates 121 and 124 on the upper side 110 are located on the first layer, and the upper connection plates 122 and 123 are located on the third layer, so that the plurality of upper connection plates are arranged in a staggered manner. Correspondingly, in the lower connecting plate corresponding to the upper connecting plate: the lower connecting plates 131 and 134 are located on the second layer, and the lower connecting plates 132 and 133 are located on the fourth layer, so that not only are the staggered arrangement of the plurality of lower connecting plates realized, but also the staggered arrangement of the plurality of lower connecting plates and the corresponding plurality of upper connecting plates are realized.
Therefore, in this embodiment, the connecting plate on one side is disposed on two layers spaced apart, and the connecting plate on the opposite side is disposed on the other two layers spaced apart. Therefore, the connecting plates on one side of the simple and exquisite structure are arranged in a staggered mode, and the connecting plates on the opposite side are also arranged in a staggered mode. On the one hand, the frame of the box body 100 is firm and stable, and on the other hand, the box body 100 can rotate around the axis 180 when being disassembled.
