Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0057] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0058] As shown in Figures 1 to 5, this application provides an installation fixture 100 for installing a display module 200. This fixture can be used to smooth the edges of the display module 200, reduce deviations in the assembly process of the components of the display module 200, and ensure that the display effect is not poor due to inconsistent splicing surfaces after the display module 200 is spliced. This effectively solves the problem of high processing precision requirements and high assembly difficulty caused by the high flatness requirements of the display surface of the display screen.

[0059] In an optional embodiment, the display module 200 includes a base shell 201, a protective structure 202, and a lamp panel 203. The lamp panel 203 and the protective structure 202 are sequentially mounted on the base shell 201 and flattened by the mounting fixture 100 to ensure the flatness of the edges of the display module 200, reduce the deviation of the components of the display module 200 during the assembly process, and ensure the display effect of the display module 200 after splicing. The display effect will not be poor due to inconsistent splicing surfaces. At the same time, the whole operation is simpler, the workload is greatly reduced, and the work efficiency is improved.

[0060] In an alternative embodiment, at least a portion of the protective structure 202 extends toward the vertical direction of the lamp panel 203 and surrounds the outside of the lamp beads 2031 of the lamp panel 203, for including the lamp beads 2031 on the lamp panel 203, especially the lamp beads 2031 at the corners of the lamp panel 203, to prevent the display module 200 from being damaged by impact during use or transportation.

[0061] In one optional embodiment, the base shell 201 has a mounting end face, the protective structure 202 is mounted on the mounting end face, and the lamp plate 203 is disposed inside the protective structure 202 and fits against the inner edge of the protective structure 202. The outer edge of the protective structure 202 is flattened by the mounting fixture 100 and is approximately flush with the base shell 201. The surface flatness between the two can be controlled within ±0.02mm, so that the protective structure 202 will not affect the display effect of the display screen after the display modules 200 are spliced, thereby maintaining a good visual effect. The thickness of the portion of the protective structure 202 extending vertically along the lamp plate 203 is between 0.01mm and 0.2mm, so that two adjacent display modules 200 can be spliced ​​together seamlessly, ensuring the display effect after the display modules 200 are spliced; at the same time, it can also protect the lamp beads 2031, preventing the display modules 200 from being damaged by impacts during use or transportation.

[0062] In an optional embodiment, the bottom shell 201 is provided with a positioning post 2012, and the protective structure 202 is provided with a positioning hole 2021. The positioning hole 2021 cooperates with the positioning post 2012 to perform preliminary pre-positioning when the protective structure 202 is installed onto the bottom shell 201. Then, the flatness of the outer edges of the bottom shell 201 and the protective structure 202 is processed by the mounting fixture 100 so that the two can be controlled to be in the same plane, or the flatness of the two can be controlled within a small range, such as within ±0.02mm, to ensure that the display effect of the display module 200 after splicing will not be poor due to the inconsistency of the splicing surface.

[0063] In an optional embodiment, the protective structure 202 includes a reinforcing rib 202b and a protective sheet 202a. The protective sheet 202a is fixed to the base shell 201 by the reinforcing rib 202b to achieve a stable fixation between the protective sheet 202a and the base shell 201. The reinforcing rib 202b not only enhances the strength of the base shell 201 but also strengthens the protective sheet 202a, preventing it from squeezing the LED bead 2031 during collisions or compression.

[0064] It should be noted that the reinforcing rib 202b can be an integral structure with the protective sheet 202a, or the reinforcing rib 202b can be a separate structure with the protective sheet 202a and then fixed together by assembly, or the protective sheet 202a can be fixed to the bottom shell 201 by the reinforcing rib 202b. This application does not impose any restrictions.

[0065] In one optional embodiment, the bottom shell 201 has a rectangular structure, the reinforcing rib 202b is a rectangular frame that is adapted to the shape of the bottom shell 201, the protective plate 202a is disposed on the outside of the bottom shell 201 and at least partly protrudes above the lamp plate 203 or is flush with the surface of the lamp bead 2031, thereby protecting the lamp bead 2031, the reinforcing rib 202b is disposed on the inside of the protective plate 202a, and the lamp plate 203 is disposed on the upper end of the reinforcing rib 202b.

[0066] In an optional embodiment, the protective sheet 202a has a horizontal section and a vertical section. The horizontal section is fixed to the bottom shell 201 by a reinforcing rib 202b, and the vertical section is not higher than the surface of the lamp bead 2031 of the lamp board 203, so as to protect the lamp bead 2031.

[0067] In an optional embodiment, the positioning hole 2021 includes a first positioning hole 2021a and a second positioning hole 2021b. The first positioning hole 2021a is disposed on the horizontal section, and the second positioning hole 2021b is disposed on the reinforcing rib 202b, so that the protective sheet 202a and the reinforcing rib 202b can be initially pre-positioned by cooperating with the positioning post 2012 through the first positioning hole 2021a and the second positioning hole 2021b. Then, the flatness of the outer edges of the bottom shell 201 and the protective structure 202 is processed by the mounting fixture 100 so that the two can be controlled in the same plane, or the flatness of the two can be controlled within a small range, such as within ±0.02mm, to ensure that the display effect of the display module 200 after splicing will not be poor due to the inconsistency of the splicing surface.

[0068] In an optional embodiment, the reinforcing rib 202b is provided with a fixing hole 2022, and the bottom shell 201 is provided with a fixing part 2013. The position of the fixing hole 2022 corresponds to the position of the fixing part 2013, so that the reinforcing rib 202b can be fixed to the fixing part 2013 through the fixing hole 2022, thereby realizing the fixed connection between the protective sheet 202a and the reinforcing rib 202b and the bottom shell 201.

[0069] In one optional embodiment, there are multiple protective sheets 202a. The multiple protective sheets 202a are arranged sequentially along the outer edge of the bottom shell 201 and surround to form an enclosing structure. The enclosing structure surrounds the outside of the lamp beads 2031 of the lamp panel 203 to protect the lamp beads 2031.

[0070] In an alternative embodiment, the protective sheet 202a has an L-shaped or T-shaped structure to enhance the overall strength of the display module 200 and prevent the corners of the bottom shell 201 from being damaged or deformed during a collision, thus rendering it unusable.

[0071] For example, there are four protective plates 202a, each with an L-shaped structure. These four protective plates 202a are respectively positioned at the four corners of the base shell 201 to protect the LED beads 2031 of the display module 200 at the corners, preventing damage from impacts during use or transportation. Furthermore, the protective plates 202a also enhance the strength of the base shell 201, preventing damage to the corners of the base shell 201 during collisions, and even preventing deformation of the module's base shell 201, rendering it unusable.

[0072] In an optional embodiment, the display module 200 further includes a mask 204, which covers the outside of the lamp beads 2031 of the lamp board 203 and contacts the protective sheet 202a. This mask can improve the display effect of the display module 200, enhance the contrast of the display screen, and even play a role in waterproofing and dustproofing.

[0073] In an optional embodiment, the face mask 204 is disposed inside the enclosure structure. That is, when the flatness of the outer edge of the protective plate 202a and the bottom shell 201 is adjusted by the installation fixture 100, the flatness of the outer edges of the lamp plate 203, the face mask 204 and the reinforcing rib 202b can be processed simultaneously, so that the outer edge of the display module 200 can be controlled in the same plane, or controlled within a small range, such as within ±0.02mm. This ensures that the display effect of the display module 200 after splicing will not be poor due to inconsistent splicing surfaces.

[0074] In an optional embodiment, as shown in Figures 1 to 3, the mounting fixture 100 includes a drive mechanism 30, a limiting mechanism 10, and a fixture base 20. The limiting mechanism 10 is mounted on the fixture base 20 and surrounds the fixture base 20 to form an accommodating space 10a. The drive mechanism 30 is pulsatorically connected to the limiting mechanism 10 and is used to drive the limiting mechanism 10 to move toward the display module 200 placed in the accommodating space 10a, so that the limiting mechanism 10 can abut against the edge of the display module 200 to ensure the display module... The edges of the group 200 can be controlled to be on the same plane so that the gap between the display modules 200 is minimized when multiple display modules 200 are spliced, thereby ensuring the display effect of the display modules 200 after splicing, and the display effect will not be poor due to inconsistent splicing surfaces; or, the driving mechanism 30 can drive the limiting mechanism 10 to move away from the display module 200 placed in the accommodating space 10a, so that the display module 200 can be placed in or removed from the accommodating space 10a.

[0075] In an optional embodiment, as shown in Figures 2, 6 to 16, the limiting mechanism 10 includes a straightening component 11 and a transmission component 12. The straightening component 11 is movably mounted on the fixture base 20. The driving mechanism 30 is connected to the straightening component 11 via the transmission component 12 and is used to drive the straightening component 11 to perform flattening treatment on the edge of the display module 200, so that the outer edge of the display module 200 can be controlled within the same plane, or within a small range, such as within ±0.02mm. This ensures that the display effect of the display module 200 after splicing will not be poor due to inconsistent splicing surfaces.

[0076] In an optional embodiment, the straightening component 11 includes a plurality of straightening blocks 111, the ends of which are opposite each other and form a rectangular accommodating space 10a, which is used to flatten the edges of the display module 200 placed in the accommodating space 10a, so that the outer edges of the display module 200 can be controlled within the same plane, or within a small range, such as within ±0.02mm, thereby ensuring that the display effect of the display module 200 after splicing will not be poor due to inconsistent splicing surfaces.

[0077] For example, there are four straightening blocks 111, with their ends facing each other. The drive mechanism 30 is connected to the four straightening blocks 111 via the transmission assembly 12, and is used to drive the four straightening blocks 111 to move simultaneously toward the display module 200 placed in the accommodating space 10a, so that the straightening blocks 111 can abut against the edge of the display module 200, so that the edge of the display module 200 can be controlled to be on the same plane, so that the gap between the display modules 200 can be minimized when multiple display modules 200 are spliced, thereby ensuring the display effect of the display modules 200 after splicing, and the display effect will not be poor due to inconsistent splicing surfaces. In addition, the drive mechanism 30 can also drive the limiting mechanism 10 to move away from the display module 200, so that the display module 200 can be placed in or removed from the accommodating space 10a.

[0078] In an optional embodiment, the straightening assembly 11 includes a limiting member 112, which is rotatably mounted on the straightening block 111 to limit the position of the display module 200, so that the limiting member 112 can press the lamp panel 203 or the mask 204 outside the lamp panel 203 of the display module 200 when the straightening block 111 abuts against the edge of the display module 200.

[0079] In an optional embodiment, the limiting member 112 includes a limiting structure 1121, a rotating shaft 1122, and an elastic member 1123. The limiting structure 1121 is rotatably mounted on the straightening block 111 via the rotating shaft 1122. The two ends of the elastic member 1123 abut against the limiting structure 1121 and the straightening block 111 respectively, so as to drive the limiting structure 1121 to press the lamp panel 203 of the display module 200 or the mask 204 on the outside of the lamp panel 203.

[0080] In an optional embodiment, the straightening block 111 has a straightening surface, the limiting member 112 is rotatably mounted on the end face opposite or adjacent to the straightening surface, and has a clamping end extending toward the inside of the accommodating space 10a to clamp the lamp panel 203 or the mask 204 of the display module 200.

[0081] For example, the straightening block 111 has a mounting groove 1113, which is located on the end face of the straightening block 111 opposite to or adjacent to the straightening surface. The limiting structure 1121 is rotatably mounted in the mounting groove 1113 via a rotating shaft 1122, and the clamping end extends toward the inner side of the accommodating space 10a. The bottom of the mounting groove 1113 is provided with a fixing groove 1115. One end of the elastic member 1123 is installed in the fixing groove 1115, and the other end of the elastic member 1123 extends out of the fixing groove 1115 and abuts against the limiting structure 1121, so that the clamping end can clamp the lamp plate 203 or the mask 204 of the display module 200.

[0082] In an optional embodiment, the limiting structure 1121 has a connecting end and an abutting end. One end of the abutting end is connected to the clamping end through the connecting end, and the rotating shaft 1122 passes through the connecting end. The straightening block 111 has a through groove 1114 that passes through the mounting groove 1113 and the straightening surface. The connecting end passes through the through groove 1114 and abuts against the outer edge of the display module 200 when the driving mechanism 30 drives the straightening block 111 to move toward the display module 200, so that the clamping end can clamp the lamp panel 203 or the mask 204 of the display module 200.

[0083] In an optional embodiment, the clamping end is provided with an abutment portion 1124 made of soft rubber material. The abutment portion 1124 contacts the surface of the display module 200 after the display module 200 is placed in the accommodating space 10a, without causing damage to the surface of the display module 200.

[0084] For example, the abutment portion 1124 contacts the lamp panel 203 or the mask 204 on the lamp panel 203 after the display module 200 is placed in the accommodating space 10a, so as to avoid the clamping end from damaging the lamp panel 203 or the mask 204.

[0085] In an optional embodiment, the mounting fixture 100 further includes a module bracket 40 disposed within the accommodating space 10a, the shape of which is adapted to the shape of the bottom shell 201 of the display module 200 for placing the display module 200.

[0086] In an optional embodiment, the module bracket 40 has a receiving cavity 41, and the bottom of the receiving cavity 41 is provided with a first magnetic member 43 for adsorbing each other with a second magnetic member provided on the bottom shell 201, so as to realize the fixed connection between the display module 200 and the module bracket 40, and solve the cumbersome problem of disassembling and assembling the display module 200 and the module bracket 40.

[0087] For example, the first magnetic attractor 43 is a magnetic attractor, and the second magnetic attractor is a metal magnetic attractor or a magnetic attractor. Alternatively, the second magnetic attractor is a magnetic attractor, and the first magnetic attractor 43 is a metal magnetic attractor or a magnetic attractor.
