[0075] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0076] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0077] Unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0078] As used herein, “parallel” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 10°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 10°.

[0079] In a video wall display device, a cabinet is used to house at least one display module. In one example, the display module may include a bracket and a light-emitting substrate it supports. The bracket is fixed to the cabinet, and the light-emitting substrate is fixed to the side of the bracket away from the cabinet. The light-emitting substrate may include a substrate and a light-emitting element disposed on the substrate. The substrate may be a glass substrate, and the light-emitting element may include a miniature inorganic light-emitting diode. In another example, the display module may also include a light-emitting substrate, which includes a printed circuit board and a light-emitting element disposed on the printed circuit board. The light-emitting element may include a miniature inorganic light-emitting diode. In this case, the light-emitting substrate can be directly fixed to the cabinet without the need for a bracket.

[0080] Furthermore, in a splicing display device, there can be multiple light-emitting substrates, which are spliced ​​together to form a spliced ​​display. For example, in a splicing display device, there is one cabinet, which carries multiple light-emitting substrates; or, for another example, there are multiple cabinets, each carrying one or more light-emitting substrates.

[0081] During the assembly of splicing display equipment, after the display module is fixed on the cabinet, due to the limitations of the manufacturing process, it is easy for the display surfaces of multiple light-emitting substrates to be not on the same plane. At this time, it is necessary to adjust the display module in the thickness direction of the light-emitting substrate until the display surfaces of multiple light-emitting substrates are on the same plane.

[0082] This disclosure provides a carrier module for carrying a component to be leveled, which may be a display module including a light-emitting substrate. Figure 1 This is a schematic diagram of the load-bearing module and the leveling component provided in some embodiments of this disclosure, such as... Figure 1 As shown, the load-bearing module includes: a housing 10, a leveling column 30, and an adjustment structure 20.

[0083] The housing 10 includes a bottom wall 11, and an adjustment structure 20 is disposed on the bottom wall 11. For example, the housing 10 may include the bottom wall 11 and a side wall 12 connected to the bottom wall 11, the bottom wall 11 and the side wall 12 defining an accommodating space Sp, and at least a portion of the adjustment structure 20 is located in the accommodating space Sp.

[0084] The leveling column 30 is used to connect the component to be leveled 80, which is positioned opposite to the housing 10. The component to be leveled 80 includes a light-emitting substrate. This light-emitting substrate can be a MiniLED light-emitting substrate or a MicroLED light-emitting substrate.

[0085] Figure 2 This is a schematic diagram showing the adjustment structure provided in some embodiments of this disclosure being disposed on the bottom wall of the housing. Figure 3 This is an exploded view of the adjustment structure and leveling column provided in some embodiments of this disclosure. Figure 4 This is a perspective view of the adjustment structure and leveling column provided in some embodiments of this disclosure when the clamping assembly is in the released state. Figure 5 This is a cross-sectional view of the adjustment structure and leveling column provided in some embodiments of this disclosure when the clamping assembly is in the released state. Figure 6 This is a perspective view of the adjustment structure and leveling column provided in some embodiments of this disclosure when the clamping assembly is in the clamping state. Figure 7 This is a cross-sectional view of the adjustment structure and leveling column provided in some embodiments of this disclosure when the clamping assembly is in the clamping state. (In conjunction with...) Figures 1 to 7 As shown, the adjustment structure 20 includes: a mounting base 3, a clamping assembly 22, and a control component 24.

[0086] The mounting base 23 is disposed on the bottom wall 11 of the housing. A clamping assembly 22 is disposed on the mounting base 23 and configured to: in a clamping state, clamp the leveling column 30 and allow the leveling column 30 to move away from the bottom wall 11 of the housing; and in a released state, release the leveling column 30. For example, in the clamping state, the clamping assembly 22 clamps the leveling column 30 and allows the leveling column 30 to move away from the bottom wall 11 of the housing, but does not allow the leveling column 30 to move closer to the bottom wall 11 of the housing. A control element 24 is disposed on the mounting base 23 and configured to: control the clamping assembly 22 to switch between the clamping state and the released state.

[0087] In this embodiment, the control component 24 can control the clamping assembly 22 to switch between a clamping state and a releasing state. In the clamping state, the clamping assembly 22 can clamp the leveling column 30 and allow the leveling column 30 to move away from the bottom wall 11 of the cabinet. In the releasing state, the clamping assembly 22 releases the leveling column 30. Therefore, when the carrier module is used in a splicing display device, each component 80 to be leveled is connected to the leveling column 30, and the clamping assembly 22 is used to clamp the component 30 to be leveled. If the distance between a component 80 to be leveled and the bottom wall 11 of the cabinet is closer than the distance between other components 80 to be leveled and the bottom wall 11 of the cabinet, the component 80 closer to the bottom wall 11 can be pulled outward (i.e., pulled away from the bottom wall 11) until multiple components 80 to be leveled are on the same plane. Alternatively, each leveling component 80 can be connected to multiple leveling components 80, and each leveling component 80 can be clamped by a clamping assembly 22. When the surface of the leveling component 80 is not parallel to the reference plane (i.e., the flatness of the leveling component 80 is low), one or more positions of the leveling component 80 can be pulled outward until the flatness of the leveling component 80 meets the requirements.

[0088] In addition, the clamping assembly 22 does not allow the leveling column 30 to move close to the bottom wall 11 of the box when it is clamped, thereby preventing the flatness of the part to be leveled 80 from being reduced due to collision.

[0089] In some embodiments, such as Figure 2 As shown, the mounting base 23 includes a receiving portion 23s. At least a portion of the control member 24 is disposed within the receiving portion 23s. The control member 24 is configured to be movable in the thickness direction of the bottom wall 11 of the housing to control the clamping assembly 22 to switch between a clamping state and a releasing state.

[0090] Figure 8 This is a perspective view of the control components provided in some embodiments of this disclosure. Figure 9 This is a perspective view of the controls and mounting base provided in some embodiments of this disclosure. Figure 8 and Figure 9 As shown, in some embodiments, the mounting base 23 includes a first protrusion 231a located within the receiving portion 23s, and a protrusion 24a is provided on the side wall of the control member 24. The control member 24 is rotatable so that the protrusion 24a overlaps the side of the first protrusion 231a near the clamping assembly 22. That is, the control member 24 is rotatable so that the protrusion 24a overlaps the surface of the first protrusion 231a near the clamping assembly 22. The rotation of the control member 24 can be a rotation of the control member 24 about its own axis.

[0091] For example, the positions of the protrusion 24a and the first protrusion 231a are configured such that when the protrusion 24a overlaps the first protrusion 231a, the control member 24 abuts against the clamping assembly 22, thereby providing a force to the clamping assembly 22 so that the clamping assembly 22 is in a released state.

[0092] In some embodiments, such as Figure 2 and Figure 3 As shown, the load-bearing module also includes an elastic element 25, which is connected to the control element 24. The elastic element 25 is configured to provide elastic force for the protrusion 24a to abut against the first protrusion 231a when the protrusion 24a overlaps the first protrusion 231a, thereby ensuring the stability of the overlap between the protrusion 24a and the first protrusion 231a when the protrusion 24a overlaps the first protrusion 231a.

[0093] In some embodiments, such as Figure 9 As shown, the mounting base 23 includes a second protrusion 231b located within the receiving portion 23s. The control member 24 is rotatable about its own axis so that the protrusion 24a overlaps the side of the second protrusion 231b near the clamping assembly 22. That is, the control member 24 is rotatable about its own axis so that the protrusion 24a overlaps the surface of the second protrusion 231b near the clamping assembly 22.

[0094] In some embodiments, the positions of the protrusion 24a and the second protrusion 231b are configured such that when the protrusion 24a overlaps the second protrusion 231b, there is no interaction force between the control member 24 and the clamping assembly 22, so that the clamping assembly 22 is in a clamping state.

[0095] In some embodiments, the distance between the second protrusion 231b and the clamping component 22 is greater than the distance between the first protrusion 231a and the clamping component 22.

[0096] In some embodiments, the elastic member 25 is further configured to provide elastic force for the protrusion 24a to abut against the second protrusion 231b when the protrusion 24a overlaps the second protrusion 231b, thereby ensuring the overlap stability of the protrusion 24a and the second protrusion 231b when the protrusion 24a overlaps the second protrusion 231b.

[0097] In some examples, there are multiple protrusions 24a, first protrusion 24a portions, and second protrusion 24a portions. The control member 24 can rotate about its own axis so that each protrusion 24a overlaps a first protrusion 24a portion, or each protrusion 24a overlaps a second protrusion 24a portion, thereby providing overlap stability in both overlap states.

[0098] In some embodiments, the first receiving portion 23s includes a first sub-receiving portion and a second sub-receiving portion. The first sub-receiving portion is located on the side of the second sub-receiving portion closer to the clamping assembly 22, and the cross-sectional area of ​​the first sub-receiving portion parallel to the bottom wall 11 of the housing is larger than the cross-sectional area of ​​the second sub-receiving portion parallel to the bottom wall 11 of the housing. Therefore, a step is formed at the junction of the first sub-receiving portion and the second sub-receiving portion. In some embodiments, the second protrusion 231b is a portion of the step at the junction of the first sub-receiving portion and the second sub-receiving portion, and the first protrusion 231a is located on another portion of the step at the junction of the first sub-receiving portion and the second sub-receiving portion.

[0099] In some embodiments, such as Figure 3 As shown, the control component 24 includes a first part 241 and a second part 242. The first part 241 is located on the side of the second part 242 close to the clamping assembly 22. The area enclosed by the outer contour of the first part 241 parallel to the cross-section of the bottom wall 11 of the housing is larger than the area enclosed by the second sub-accommodating part 23s parallel to the outer contour of the cross-section of the bottom wall 11 of the housing.

[0100] For example, the orthographic projection of the first part 241 onto the reference plane is the first projection, and the orthographic projection of the second part 242 onto the reference plane is the second projection. The outer contour of the first projection surrounds the second projection. The reference plane is a plane parallel to the bottom wall 11 of the housing. For example, the outer contours of both the first and second projections are circular.

[0101] In some embodiments, such as Figure 2 and Figure 3 As shown, one end of the elastic member 25 is connected to the side of the first part 241 away from the clamping assembly 22, and the other end of the elastic member 25 is connected to the side of the mounting base 23 away from the clamping assembly 22, or the other end of the elastic member 25 is connected to the bottom wall 11 of the housing.

[0102] Specifically, when the protrusion 24a overlaps the first protrusion 24a, the elastic member 25 is in a stretched state, thereby providing a tensile force for the protrusion 24a to overlap with the first protrusion 24a portion. When the protrusion 24a overlaps the second protrusion 24a, the elastic member 25 is in a stretched state, thereby providing a tensile force for the protrusion 24a to overlap with the second protrusion 24a portion.

[0103] In one example, the elastic element 25 is a spring. In another example, there are multiple elastic elements 25, which are evenly distributed around the second part 242.

[0104] In some embodiments, such as Figure 2 As shown, a mounting hole V1 is provided on the bottom wall 11 of the housing, and the mounting base 23 passes through the mounting hole V1. For example, the mounting base 23 is a cylindrical structure surrounding the control element 24.

[0105] In one example, the control element 24 also passes through the mounting hole V1, or the control element 24 is positioned opposite to the mounting hole V1 so that a force can be applied to the control element 24 from outside the housing 10 so that the control element 24 moves along the thickness direction of the bottom wall 11 of the housing.

[0106] In some embodiments, such as Figure 3 As shown, a knob 26 is provided at the end of the control member 24 away from the leveling member 80, so that the operator can rotate the control member 24 by controlling the knob 26. In one example, the knob 26 can be formed as an integral structure with the control member 24.

[0107] In some embodiments, such as Figure 2 and Figure 3 As shown, the mounting base 23 includes a first mounting portion 231 and a second mounting portion 232. The first mounting portion 231 and the second mounting portion 232 are detachably connected to facilitate the assembly and disassembly of the mounting base 23 from the housing 10. For example, the first mounting portion 231 and the second mounting portion 232 are connected by threads. In some embodiments, at least a portion of the first mounting portion 231 is located on the side of the bottom wall 11 of the housing near the clamping assembly 22, and at least a portion of the second mounting portion 232 is located on the side of the bottom wall 11 of the housing away from the clamping assembly 22, with the first mounting portion 231 located on the side of the second mounting portion 232 near the clamping assembly 22.

[0108] In some embodiments, at least one of the first mounting portion 231 and the second mounting portion 232 passes through the mounting hole V1. Figure 2 In the illustrated embodiment, the example is that the first mounting portion 231 passes through the mounting hole V1. In other examples, the second mounting portion 232 may also pass through the mounting hole V1.

[0109] In some embodiments, such as Figure 2 As shown, the second mounting portion 232 includes a second mounting portion bottom wall 2322, which is disposed opposite to the mounting hole V1. In one example, the end of the first mounting portion 231 away from the clamping assembly 22 may be supported on the second mounting portion bottom wall 2322, or there may be a gap between the first mounting portion 231 and the second mounting portion bottom wall 2322.

[0110] In some embodiments, such as Figure 2 As shown, the second mounting portion 232 may further include a second mounting portion sidewall 2321, which is connected to the second mounting portion bottom wall 2322; for example, the two may be an integral structure. The second mounting portion sidewall 2321 may be located on the side of the housing bottom wall 11 away from the clamping assembly 22. The second mounting portion sidewall 2321 may be detachably connected to the first mounting portion 231.

[0111] In some embodiments, the other end of the elastic member 25 is connected to the bottom wall 2322 of the second mounting portion.

[0112] In some embodiments, the first mounting portion 231 includes a first sub-mounting portion 2311 and a second sub-mounting portion 2312. The first sub-mounting portion 2311 is located on the side of the bottom wall 11 of the housing close to the clamping assembly 22, and the second sub-mounting portion 2312 passes through the mounting hole V1 and protrudes from the side of the bottom wall 11 of the housing away from the clamping assembly 22.

[0113] In one example, both the first sub-mounting portion 2311 and the second sub-mounting portion 2312 can be cylindrical structures. The first sub-receiving portion is the space surrounded by the first sub-mounting portion 2311, and the second sub-receiving portion is the space surrounded by the second sub-mounting portion 2312. The second protrusion 231b can be considered as a portion of the end face of the second sub-mounting portion 2312 facing the clamping assembly 22, and the second protrusion 231b is located on the end face of the second sub-mounting portion 2312 facing the clamping assembly 22.

[0114] In some embodiments, the second mounting portion sidewall 2321 of the second mounting portion 232 contacts and surrounds the second sub-mounting portion 2312. The second mounting portion sidewall 2321 and the second sub-mounting portion 2312 are detachably connected.

[0115] In some embodiments, such as Figure 3 As shown, the clamping assembly 22 includes a plurality of spring tabs 221, each spring tab 221 having a second end, the second ends of the plurality of spring tabs 221 being close to each other. The second end of each spring tab 221 includes a notch 22a for clamping the leveling post 30. For example, the leveling post 30 has a circular cross-section parallel to the bottom wall 11 of the housing, and the notch 22a can be an arc-shaped notch.

[0116] The notches 22a of the multiple spring clips 221 define a clamping area. When the notches 22a are arc-shaped, they define a circular clamping area. The control member 24 supports the second end of each spring clip 221. For example, when the protrusion 24a on the control member 24 overlaps the first protrusion 231a, the control member 24 applies a force away from the bottom wall 11 of the housing to the second end of each spring clip 221, thus lifting the second end of each spring clip 221. The diameter of the clamping area defined by the notches 22a of the multiple spring clips 221 is larger, thereby releasing the leveling post 30. When the protrusion 24a on the control member 24 overlaps the second protrusion 231b, the control member 24 no longer applies a force to the spring clips 221. At this time, the notches 22a of the multiple spring clips 221 jointly clamp the leveling post 30.

[0117] It should be noted that, Figure 3The illustration uses a clamping assembly 22 comprising two spring pieces 221 as an example. Of course, the clamping assembly 22 may include a greater number of spring pieces 221.

[0118] In some embodiments, the spring 221 further includes a first end, wherein the first end and the second end of the same spring 221 are disposed opposite to each other, the first ends of multiple springs 221 are far apart from each other, and the first end of each spring 221 is fixed to the side of the mounting base 23 away from the bottom wall 11 of the housing.

[0119] In one example, the first end of each spring 221 is secured to the mounting base 23 by a fastener 27 such as a screw. In another example, the mounting base 23 is provided with a groove, and the first end of each spring 221 can be secured in the groove by the fastener 27.

[0120] In some embodiments, such as Figures 2 to 7 As shown, the leveling post 30 includes a connecting portion 32 and a main body portion 31. The connecting portion 32 is used to connect to the part to be leveled 80. For example, the connecting portion 32 can be a stud, so that it can be connected to a threaded hole on the part to be leveled 80, and it is convenient to assemble and disassemble the connecting portion 32 and the part to be leveled 80.

[0121] like Figures 2 to 7 As shown, the main body 31 is connected to the connecting part 32, and the notch 22a is used to clamp the main body 31 of the leveling column 30. Figure 10A This is a schematic diagram of the clamping assembly clamping the leveling column provided in some embodiments of this disclosure, such as... Figure 10A As shown, in some embodiments, the area of ​​the main body 31 parallel to the cross-section of the component 80 gradually decreases or decreases in a stepped manner along the direction away from the component 80 to be leveled. This design is to prevent the component 80 to be leveled from moving close to the bottom wall 11 of the housing under external pressure while the clamping assembly 22 is holding the main body 31.

[0122] In some embodiments, such as Figure 10AAs shown, the longitudinal section of the main body 31 is trapezoidal and has: a top edge close to the leveling component 80, and a first side edge E1 and a second side edge E2 connected to both ends of the top edge, respectively. The first side edge E1 and the second side edge E2 are straight edges. Here, the longitudinal section of the main body 31 refers to the section passing through its own center of gravity and along the direction close to and away from the leveling component 80, and this section is perpendicular to the leveling component 80. The acute angle α between the first side edge E1 and the leveling component 80, and the acute angle β between the second side edge E2 and the leveling component 80 are both less than or equal to 85°, so that when the control component 24 moves a certain distance away from the bottom wall 11 of the housing, the spring piece 221 has a large deformation. In one example, the top edge of the longitudinal section of the main body 31 is parallel to the leveling part 80. The acute angle α between the first side E1 and the leveling part 80 is also the angle between the first side E1 and the top edge; the acute angle β between the second side E2 and the leveling part 80 is also the angle between the second side E2 and the top edge.

[0123] In one example, the acute angle α between the first side E1 and the leveling part 80 and the acute angle β between the second side E1 and the leveling part 80 are both within the range of [75°, 85°]. For example, the acute angle between the first side E1 and the leveling part 80 and the acute angle between the second side E1 and the leveling part 80 are both 75°, or both are 80°, or both are 85°.

[0124] Of course, in other embodiments, the first side E1 and the second side E2 can also be curved sides.

[0125] Figure 10B This is a top view of the clamping assembly provided in some embodiments of this disclosure, such as... Figure 10B As shown, in some embodiments, the plurality of spring pieces 221 are in their natural state, and the clamping area Q defined by the notches 22a of the plurality of spring pieces 221 (i.e., Figure 10B The orthographic projection of the gray area (in the image) onto the reference plane is located within the orthographic projection range of the end face of the main body 31 near the bottom wall 11 of the housing onto the reference plane. The reference plane is the extension surface of the spring piece 221 in its natural state. The spring pieces 221 being in their natural state means that they are not supported by the control member 24 and are not clamping the leveling column 30. In this state, the orthographic projection of the clamping area Q onto the reference plane is located within the orthographic projection range of the end face of the main body 31 near the bottom wall 11 of the housing onto the reference plane, thus ensuring that any position of the main body 31 can be clamped by the clamping assembly 22.

[0126] In some embodiments, such as Figure 2 and Figure 8As shown, the control member 24 has a receiving cavity 24s, the receiving cavity 24s has an opening 24s1 facing the leveling member 80, and the receiving cavity 24s is configured such that when the clamping assembly 22 is in the clamping state, the receiving leveling column 30 is located at least a portion between the clamping assembly 22 and the bottom wall 11 of the housing.

[0127] In some embodiments, such as Figure 2 As shown, a seal 50 is provided between the mounting base 23 and the bottom wall 11 of the housing to prevent external dust or moisture from entering the interior of the housing 10 through the gap between the mounting base 23 and the bottom wall 11. For example, a seal 50 is provided between the first mounting part 231 and the surface of the bottom wall 11 facing the part to be leveled 80, and / or, a seal 50 is provided between the second mounting part 232 and the surface of the bottom wall 11 away from the clamping assembly 22. The seal 50 can be a sealing ring made of a flexible material (e.g., rubber). Figure 2 The diagram shows a case where a seal 50 is provided both between the first mounting portion 231 and the surface of the bottom wall 11 of the housing facing the leveling component 80, and between the second mounting portion 232 and the surface of the bottom wall 11 of the housing facing away from the clamping assembly 22. It should be noted that the seal 50 can also be provided in other locations, as long as it can seal the gap between the mounting base 23 and the bottom wall 11 of the housing. For example, a seal can be provided between the side wall of the mounting hole V1 and the mounting base 23.

[0128] In some preferred embodiments, when at least a portion of the mounting base 23 is located on the side of the bottom wall 11 of the housing away from the leveling component 80, a seal 50 is provided between the mounting base 23 and the surface of the bottom wall 11 away from the leveling component 80. This prevents external dust or moisture from entering the mounting hole V1 and the interior of the housing 10. For example, the seal 50 may be provided only between the surface of the bottom wall 11 away from the leveling component 80 and the mounting base 23; or, for another example, the seal 50 may be provided between the surface of the bottom wall 11 away from the leveling component 80 and the mounting base 23, while also providing a seal 50 between the surface of the bottom wall 11 facing the leveling component 80 and the mounting base 23.

[0129] It should also be noted that in some other embodiments, the first mounting part 231 may be integrally formed with the bottom wall 11 of the box, and there is no gap between the first mounting part 231 and the bottom wall 11 of the box. In this case, the sealing element 50 may be provided only between the second mounting part 232 and the bottom wall 11 of the box; or, the second mounting part 232 may be integrally formed with the bottom wall 11 of the box, and there is no gap between the second mounting part 232 and the bottom wall 11 of the box. In this case, the sealing element 50 may be provided only between the first mounting part 231 and the bottom wall 11 of the box.

[0130] Figure 11This is a top view of the bottom wall of the housing, the first fixing member, and the adjustment structure provided in some embodiments of this disclosure, such as... Figure 11 As shown, in some embodiments, the bottom wall 11 of the box is polygonal, and adjustment structures 20 are provided near at least three sides or at least three corners of the bottom wall 11 of the box, so as to facilitate the adjustment of the flatness of the flattening component 80.

[0131] In one example, the bottom wall 11 of the box is quadrilateral. For example, a rectangle, a square, etc. In one example, an adjustment structure 20 is provided near each corner or each side of the bottom wall 11 of the box.

[0132] It should be noted that "near the edge" means that the distance to the edge does not exceed 1 / 4, 1 / 5, 1 / 6, 1 / 7, 1 / 8, 1 / 9, 1 / 10, or 1 / 15 of the shortest side length of the polygon. "Near the corner" means that the distance to the vertex does not exceed 1 / 4, 1 / 5, 1 / 6, 1 / 7, 1 / 8, 1 / 9, 1 / 10, or 1 / 15 of the shortest side length of the polygon.

In one example, the end of the first fixing member 40 facing the second fixing member 41 is magnetic, and the second fixing member 41 is made of iron. For example, the first fixing member 40 includes a support column and a magnet disposed on the support column; or, for another example, the first fixing member 40 is entirely a magnetic column. In another example, the second fixing member 41 is magnetic, and the end of the first fixing member 40 facing the second fixing part is made of iron. For example, the first fixing member 40 includes a support column and an iron block disposed on the support column. In yet another example, both the end of the first fixing member 40 facing the second fixing member 41 and the end of the second fixing member 41 facing the first fixing member 40 are magnetic, and the magnetic properties at the two ends are opposite.

[0134] In one example, a first fastener 40 is provided near each corner and each side of the bottom wall 11 of the housing. In another example, a first fastener 40 is provided near each corner and at least one side of the bottom wall 11 of the housing.

[0135] In some embodiments, there is a gap between the first fixing member 40 and the second fixing member 41, thereby providing adjustment space for the leveling member 80 in the thickness direction of the bottom wall 11 of the housing.

[0136] In some embodiments, the leveling component 80 can be supported on the side wall 12 of the housing.

The bracket is connected to the leveling post 30. For example, a threaded hole may be provided on the bracket for threaded connection with the leveling post 30. A second fixing member 41 may also be disposed on the bracket.

[0140] In other embodiments, when the substrate of the light-emitting substrate is a printed circuit board, the bracket may not be required. For example, a mounting block may be provided on the printed circuit board, and a threaded hole may be provided on the mounting block for threaded connection with the leveling post 30.
