[0044] The inventor discovered through research that... (Please refer to...) Figure 1The module housing 300' is equipped with adjusting screws for adjusting flatness. The module housing 300' is rectangular in shape, and the adjusting screws are located at the four corners of the module housing 300', with two adjusting screws at each corner. During the assembly of the module housings 300', the adjusting screws can be used for "pulling" and "pushing" operations to adjust the supporting areas of adjacent module housings 300' to a flat plane. However, achieving the required flatness between adjacent module housings 300' is difficult, and this method is cumbersome and inefficient.
[0045] In view of this, this embodiment provides a solution that can solve the above problems. The solution provided in this embodiment will be described in detail below.
[0046] Please refer to Figure 2 , Figure 2 Example: The flatness adjustment device provided in this embodiment may include a base 100 and at least two locking components 200.
[0047] The base 100 may include a flat area.
[0048] In this embodiment, the flat area can be a part of a surface of the base 100 or the entire surface of the base 100. The flat area refers to an area without undulations or protrusions that can maintain a horizontal or flat state.
[0049] The base 100 can be made of high-strength and high-hardness steel, such as Cr12 steel or tool steel, which ensures that the flatness adjustment device will not deform during use and can be used multiple times.
[0050] At least two locking components 200 may be located at the edge of the flat area and connected to the base 100. The locking components 200 may include an elastic member 210 and a limiting member 220. One end of the elastic member 210 may be connected to the base 100, and the other end of the elastic member 210 may be connected to the limiting member 220.
[0051] At least two locking components 200 can be used to lock and connect to different module housings 300 respectively. When the locking components 200 are locked and connected to the module housings 300, the elastic member 210 can drive the locking components 200 to apply a pulling force to the module housings 300 so that the flat area abuts against the module housings 300.
[0052] In this embodiment, the module housing 300 may include a supporting area 310 for abutting against the flat area. During the splicing of the module housing 300, the positions of each module housing 300 can be adjusted first so that the supporting areas 310 of at least two module housings 300 to be spliced come into contact with each other. Then, the flat area of the base 100 comes into contact with the supporting area 310 of the module housing 300, and the limiting member 220 is connected to the module housing 300. At this time, the elastic member 210 can apply a pulling force to the module housing 300 in the direction close to the center of the flat area, and the supporting area 310 of each module housing 300 is fixed on the same horizontal plane by the supporting area of the flat area of the base 100 against the module housing 300. In this way, the splicing of each module housing 300 can be realized.
[0053] The area of the flattened area can be greater than or equal to the sum of the areas of the supporting areas 310 of each modular box 300 that need to be spliced. The shape of the flattened area can be the same as the shape of the supporting area 310, or the shape of the flattened area can be different from the shape of the supporting area 310. For example, the flattened area is circular, and the area of the supporting area 310 formed by each modular box 300 that needs to be spliced is also circular; or, the flattened area is circular, and the area of the supporting area 310 formed by each modular box 300 that needs to be spliced is rectangular.
[0054] In some examples, please refer to Figure 3 The module housing 300 can be rectangular in shape. The supporting area 310 of the module housing 300 can be located at the four corners of the rectangle. Each module housing 300 can include four supporting areas 310. When the module housings 300 are spliced, the supporting areas 310 of adjacent module housings 300 can contact each other to form supporting areas 310 corresponding to the flat area of the base 100.
[0055] In one possible implementation, please refer to Figure 4 When there are two locking components 200, the two locking components 200 can be symmetrically distributed and located on opposite sides of the flat area. In this way, the two locking components 200 can be connected to the two module housings 300 respectively, realizing the splicing of the two module housings 300.
[0056] When the flat area of the base 100 is circular, the line connecting the two locking components 200 can pass through the center of the flat area. When the flat area of the base 100 is rectangular, the two locking components 200 can be located on opposite sides of the flat area, and both can be located at the center of the side.
[0057] In another possible implementation, please refer to Figure 5When there are four locking components 200, the four locking components 200 can be symmetrically distributed, and each of the four locking components 200 is connected to one of the four module housings 300. In this way, the four locking components 200 can be used to connect the four module housings 300.
[0058] When the flat area of the base 100 is circular, the four locking components 200 can be evenly distributed along the periphery of the flat area. When the flat area of the base 100 is rectangular, the four locking components 200 can be located on the four sides of the flat area, and can all be located at the center of the side.
[0059] Based on the above design, in the flatness adjustment device provided in this embodiment, the flatness between each module box 300 can be guaranteed by the contact between the flat area of the base 100 and the abutment area 310 of the module box 300. Furthermore, by applying a pulling force to the module box 300 through the locking component 200, the module box 300 can be prevented from shifting position during the splicing process. In this way, the convenience of splicing the module box 300 can be improved, and work efficiency can be increased.
[0060] In one possible implementation, please refer to Figure 6 The flatness adjustment device may also include a connecting component 400, and the locking component 200 may be connected to the base 100 via the connecting component 400.
[0061] In this embodiment, the base 100 is provided with a first connecting hole 110, which can be located at the edge of the flat area. The locking component 200 is provided with a second connecting hole 230, which can be fixedly connected to the elastic component 210. The connecting component 400 can connect the locking component 200 and the base 100 through the first connecting hole 110 and the second connecting hole 230.
[0062] The connecting component 400 may include a pivot extending along a first direction parallel to the flat area, the first direction being perpendicular to a second direction, which may be a direction away from the center of the flat area.
[0063] In this embodiment, the shaft of the connecting component 400 can be used to connect a locking component 200 and a base 100 through two first connecting holes 110 and one second connecting hole 230. The two ends of the shaft are respectively provided with threads, and the radius of the middle position of the shaft can be smaller than the radius of the two ends of the shaft. The two first connecting holes 110 can be threaded holes, and the second connecting hole 230 can be located between the two first connecting holes 110. In this way, the shaft of the connecting component 400 can pass through one first connecting hole 110, one second connecting hole 230 and one first connecting hole 110 in sequence to connect a locking component 200 and a base 100.
[0064] The second connecting hole 230 is not fixedly connected to the rotating shaft of the connecting component 400. The second connecting hole 230 can rotate relative to the rotating shaft of the connecting component 400. Therefore, the locking component 200 can rotate about the rotating shaft of the connecting component 400.
[0065] In one possible implementation, please refer to Figure 7 The locking assembly 200 may include a first part and a second part connected to each other. The second part is farther away from the base 100 than the first part, and the width W2 of the second part is greater than the width W1 of the first part in a direction parallel to the flat area.
[0066] In this embodiment, the first part of the locking assembly 200 can be connected to the base 100, and the second part of the locking assembly 200 can be connected to the first part. By setting the width W2 of the second part to be greater than the width W1 of the first part, the locking assembly 200 can be connected to the module housing 300, thereby applying a pulling force to the module housing 300 in a direction close to the center of the flat area through the elastic member 210.
[0067] In one possible implementation, the first part may include a spring, and the second part may include a sphere, the diameter of which may be greater than the width of the spring.
[0068] In one possible implementation, the base 100 may include a first surface and a second surface disposed opposite to each other, and a flat area of the base 100 may be located on the first surface and / or the second surface. The base 100 may also include a side surface located between the first surface and the second surface.
[0069] In a first possible implementation, when the flat area of the base 100 is located only on the first surface of the base 100, the flat area can be a portion or the entirety of the first surface. If the flat area is a portion of the first surface, the locking assembly 200 can be located in other areas of the first surface or on the side of the base 100. If the flat area is the entirety of the first surface, the locking assembly 200 can be located on the side of the base 100.
[0070] In a second possible implementation, when the flat area of the base 100 is located only on the second surface of the base 100, the flat area can be a portion or the entirety of the second surface. If the flat area is a portion of the second surface, the locking assembly 200 can be located in other areas of the second surface or on the side of the base 100. If the flat area is the entirety of the second surface, the locking assembly 200 can be located on the side of the base 100.
[0071] In a third possible implementation, when the flat area of the base 100 is located on the first surface and the second surface of the base 100, the flat areas of the first surface and the second surface are symmetrically arranged. If the flat area of the first surface is a part of the first surface, then the flat area of the second surface is also a part of the second surface. In this case, the locking component 200 can be located on the first surface or other areas of the second surface, or the locking component 200 can be located on the side of the base 100. If the flat area of the first surface is the entire first surface, then the flat area of the second surface is also the entire second surface. In this case, the locking component 200 can be located on the side of the base 100.
[0072] In the above design, when the flat area of the base 100 is located on both the first and second surfaces of the base 100, the flat areas of the first and second surfaces can contact the abutment area 310 of the module housing 300. At this time, the locking component 200 can be connected to the module frame by rotating the locking component 200 around the pivot of the connecting component 400.
[0073] In one possible implementation, the flatness of the flat area can be less than or equal to 0.05 mm.
[0074] This application also provides a display screen, which may include at least two module housings 300 and display modules respectively located within the module housings 300. Each module housing 300 may include a positioning groove 320 that cooperates with the flatness adjustment device provided in this application. When the locking component 200 of the flatness adjustment device engages with the positioning groove 320, the elastic component can drive the locking component 200 to apply a pulling force to the module housing 300, causing the flat area to abut against the module housing 300.
[0075] In this embodiment, when splicing the module housing 300, the position of the module housing 300 to be spliced can be adjusted first, and the flat area of the base 100 can be made to contact the abutting area 310 of the module housing 300 to be spliced. Then, the limiting component 220 of the locking component 200 can be inserted into the positioning groove 320, so that the elastic component drives the locking component 200 to apply a pulling force to the module housing 300. In this way, multiple module housings 300 can be pulled together and locked onto a plane.
[0076] In one possible implementation, please refer to Figure 8The module housing 300 may include a bearing region 310 for abutting against a flat area, and a positioning groove 320 may extend in a direction away from the bearing region 310. The positioning groove 320 may include a first region 321 and a second region 322 that are interconnected. In the extension direction perpendicular to the positioning groove 320, the opening width of the first region 321 of the positioning groove 320 away from the bearing region 310 may be greater than the opening width of the second region 322 near the bearing region 310.
[0077] In this embodiment, the opening shape of the first region 321 can be the same as the shape of the limiting member 220. For example, when the limiting member 220 is a sphere, the opening shape of the first region 321 can be circular, and the opening shape of the second region 322 can be rectangular. In this case, the opening width of the second region 322 can be smaller than the diameter of the limiting member 220. In this way, it can be ensured that the limiting member 220 is inserted into the positioning groove 320 of the module housing 300.
[0078] This application also provides a method for splicing displays, please refer to... Figure 9 The splicing method for the display screen may include the following steps.
[0079] Step S110: Provide a flatness adjustment device.
[0080] In this embodiment, the flatness adjustment device may include a base 100 and at least two locking components 200. The base 100 may include a flat area, and the at least two locking components 200 may be located at the edge of the flat area and connected to the base 100. The locking components 200 may include an elastic member 210 and a limiting member 220. One end of the elastic member 210 may be connected to the base 100, and the other end of the elastic member 210 may be connected to the limiting member 220.
[0081] Step S120: Provide at least two module housings 300.
[0082] In this embodiment, at least two module housings 300 can be identical, and the module housing 300 can include a positioning groove 320 that cooperates with the flatness adjustment device.
[0083] In step S130, the locking component 200 of the flatness adjustment device is inserted into the positioning groove 320 of the module housing 300. The elastic component drives the locking component 200 to apply a pulling force to the module housing 300 so that the flat area abuts against the module housing 300, so that at least two module housings 300 are located on the same plane.
[0084] In this embodiment, the positions of at least two module housings 300 can be initially adjusted so that the flat area of the base 100 contacts the abutment area 310 of the module housing 300 to be assembled. Then, the limiting component 220 of the locking assembly 200 is inserted into the positioning groove 320 of the module housing 300, so that the elastic component applies a pulling force to the module housing 300. In this way, multiple module housings 300 can be pulled together and locked onto a plane. At this time, adjacent module housings 300 can be fixed by fasteners. After fixing, the flatness adjustment device can be removed. The fasteners used to fix adjacent module housings 300 can include, but are not limited to, screws and rivets.
[0085] Step S140: Place at least two display modules into at least two module housings 300 respectively.
[0086] In this embodiment, each display module can be placed inside the assembled module housing 300.
[0087] In summary, the embodiments of this application provide a flatness adjustment device, a display screen, and a splicing method for the display screen. By contacting the flat area of the base with the abutting area of the module cabinet, the flatness between each module cabinet can be ensured. Furthermore, by applying tension to the module cabinet through the locking component, positional displacement of the module cabinet during splicing can be avoided. Thus, the convenience of splicing the module cabinet can be improved, and work efficiency can be increased.
