[0068] like Figures 1 to 4As shown, according to an embodiment of the present application, a light-emitting module 1 is proposed, which includes a support plate 11, a fixing component 12 and a light-emitting panel 13. The fixing component 12 includes a support column 121 and a first magnetic portion 122, one end of the support column 121 is fixed to the support plate 11, and one end of the support column 121 away from the support plate 11 is provided with a first positioning surface 1211 and a supporting surface 1212, the first magnetic portion 122 is fixed to the supporting surface 1212, and the surface of the first magnetic portion 122 away from the support plate 11 is close to the support plate 11 relative to the first positioning surface 1211, or in other words, the first positioning surface 1211 is close to the light-emitting panel 13 relative to the surface of the first magnetic portion 122 away from the support plate 11. The light-emitting panel 13 is located on a side of the fixing component 12 away from the supporting plate 11. The light-emitting panel 13 includes a main body 131. A second magnetic attraction portion 132 is provided on a surface of the main body 131 facing the supporting plate 11. A second positioning surface 133 is provided on the side of the light-emitting panel 13 facing the supporting plate 11. The second positioning surface 133 is contacted and positioned correspondingly with the first positioning surface 1211. The second magnetic attraction portion 132 and the first magnetic attraction portion 122 are attracted to each other. A first isolation gap L1 is provided between the second magnetic attraction portion 132 and the first magnetic attraction portion 122.

[0069] The light-emitting module 1 provided in the present application includes a support plate 11, a fixing component 12 and a light-emitting panel 13, and the fixing component 12 is used to fix the support plate 11 and the light-emitting panel 13. The fixing component 12 includes a support column 121, and the support column 121 is used to support and position the light-emitting panel 13. The support column 121 includes a first end and a second end that are arranged opposite to each other, and the first end of the support column 121 is fixed to the support plate 11, and the second end of the support column 121 is provided with a first positioning surface 1211, and the first positioning surface 1211 is used to position and support the light-emitting panel 13. The fixing component 12 also includes a first magnetic attraction portion 122, and the second end of the support column 121 is also provided with a supporting surface 1212, and the first magnetic attraction portion 122 is fixed to the supporting surface 1212, so that the first magnetic attraction portion 122 is fixed to the end of the support column 121 away from the support plate 11. The light-emitting panel 13 includes a main body 131 and a second magnetic portion 132, the second magnetic portion 132 is located on the surface of the main body 131 facing the support plate 11, the second magnetic portion 132 cooperates with the first magnetic portion 122 to achieve the fixation of the light-emitting panel 13 and the support column 121, and a second positioning surface 133 is formed on the light-emitting panel 13, the second positioning surface 133 cooperates with the first positioning surface 1211 to achieve the support and positioning of the light-emitting panel 13 by the support column 121, because the surface of the first magnetic portion 122 away from the support plate 11 is closer to the support plate 11 than the first positioning surface 1211, so that there is a first isolation gap L1 between the second magnetic portion 132 and the first magnetic portion 122, so that the first magnetic portion 122 and the second magnetic portion 132 are not in direct contact, so that the positioning of the light-emitting panel 13 is achieved only by the first positioning surface 1211 and the second positioning surface 133, which helps to improve the positioning accuracy. In the light-emitting module 1 provided in the present application, the positioning and support of the light-emitting panel 13 are achieved by the support column 121 in the fixing component 12, and the fixing of the light-emitting panel 13 is achieved by the magnetic attraction of the first magnetic attraction portion 122 and the second magnetic attraction portion 132. Since the first magnetic attraction portion 122 and the first positioning surface 1211 are both located at the end of the support column 121 away from the support plate 11, the distance between the two is relatively close, so that the support point of the support column 121 for the light-emitting panel 13 (that is, the first positioning surface 1211) and the fixing point of the support column 121 and the light-emitting panel 13 (that is, the first magnetic attraction portion 122 and the second magnetic attraction portion 132) are relatively close, so that the light-emitting panel 13 is not prone to local deformation while being fixed, thereby improving the flatness of the light-emitting panel 13, thereby helping to improve the display effect of the light-emitting module 1.

[0070] The number of the fixing components 12 can be multiple, and the multiple fixing components 12 are arranged at intervals between the support plate 11 and the light-emitting panel 13. The first positioning surface 1211 of each fixing component 12 can support and position the light-emitting panel 13, and the first magnetic attraction part 122 in each fixing component 12 is adsorbed with the corresponding second magnetic attraction part 132 for fixed positioning.

[0071] In the related art, a plurality of second support planes are formed on the support plate, and different second support planes have different shapes, and a first magnetic member is formed on the support plate and is spaced apart from the second support plane, the first magnetic member is spaced apart from the first support plane, the first magnetic member is located on one side of the first support plane, different first magnetic members are located on different sides of different first support planes, and the distance between the first magnetic member and the first support plane is relatively far. A plurality of second support planes are formed on the surface of the side of the light-emitting panel facing the support plate, and different second support planes have different shapes, and a plurality of second magnetic members are formed on the side of the light-emitting panel facing the support plate, the second magnetic member is spaced apart from the second support plane, the second magnetic member is located on one side of the second support plane, different second magnetic members are located on different sides of different second support planes, and the distance between the second magnetic member and the second support plane is relatively far. The first support plane cooperates with the second support plane to realize the support of the light-emitting panel, and the first magnetic attraction member cooperates with the second magnetic attraction member to realize the fixation of the light-emitting panel. However, since the support force between the first support plane and the second support plane and the magnetic attraction force between the first magnetic attraction member and the second magnetic attraction member are in different positions, the distance between the two forces is far, so that the light-emitting panel is prone to distortion. In the light-emitting module 1 provided in the present application, by setting a plurality of identical fixing components 12, the difference at different fixing positions can be reduced, and in the fixing component 12, the first positioning surface 1211 and the first magnetic attraction portion 122 are both located at one end of the support column 121 away from the support plate 11, and the distance between the two is close, so that the support force between the first positioning surface 1211 and the second positioning surface 133 and the magnetic attraction force between the first magnetic attraction portion 122 and the second magnetic attraction portion 132 are in a similar position, which can reduce the deflection moment between the magnetic attraction force and the support force at the corresponding position of each fixing component 12, so that the light-emitting panel 13 is not easy to be distorted, so as to improve the flatness of the light-emitting panel 13.

[0072] It should be noted that the use of the first magnetic attraction part 122 and the second magnetic attraction part 132 in the present disclosure does not mean that the first magnetic attraction part 122 and the second magnetic attraction part 132 are both magnetic, but it should be understood that at least one of the first magnetic attraction part 122 and the second magnetic attraction part 132 is magnetic, which can achieve the attraction between the first magnetic attraction part 122 and the second magnetic attraction part 132. For example, the first magnetic attraction part 122 can be a magnet with magnetism, and the second magnetic attraction part 132 can be an object that can be attracted by magnetism; or, the second magnetic attraction part 132 can be a magnet with magnetism, and the first magnetic attraction part 122 can be an object that can be attracted by magnetism; or, the first magnetic attraction part 122 and the second magnetic attraction part 132 are both magnets with magnetism, one is an N-type magnet, and the other is an S-type magnet, so that the two can attract each other. In the above embodiment, the positioning of the support column 121 and the light-emitting panel 13 is achieved by contacting the first positioning surface 1211 with the second positioning surface 133, which can reduce the variables in the positioning process, thereby improving the positioning accuracy. Specifically, since the first positioning surface 1211 is formed on the support column 121 , the position of the first positioning surface 1211 relative to the support column 121 is fixed, and no process error will be generated due to the existence of other components, thereby improving the positioning accuracy.

[0073] Specifically, if Figure 5 As shown, the light emitting module 1 may be a spliced ​​light emitting module 1, including a plurality of light emitting panels 13 fixed on the same support plate 11, and the plurality of light emitting panels 13 are spliced ​​to form a larger display area.

[0074] Specifically, the light-emitting panel 13 includes COB (chip on board, i.e., LED chips on PCB substrate), SMD (Surface Mounted Devices, i.e., surface mount devices), COG (chip on glass, i.e., LED chips on glass substrate) and other types of light-emitting panels 13.

[0075] Specifically including: Mini-LED light-emitting panel 13 or Micro-LED light-emitting panel 13 .

[0076] Specifically, if Figure 6 As shown, a plurality of fixing components 12 can be fixed on the support plate 11, a plurality of light emitting panels 13 can be fixed on one side of the support plate 11, and each light emitting panel 13 can correspond to a plurality of fixing components 12. The plurality of fixing components 12 corresponding to the same light emitting panel 13 are evenly distributed.

[0077] Specifically, each light emitting panel 13 may correspond to 9 fixing components 12 , and the 9 fixing components 12 are arranged in an array, wherein 8 fixing components 12 are used to support the edges of the light emitting panel 13 , and the remaining 1 fixing component 12 may be used to support the center of the light emitting panel 13 .

[0078] In a feasible implementation manner, the first positioning surface 1211 and the first magnetic attraction portion 122 are nested with each other.

[0079] In the above implementation, if Figure 2 and Figure 4 As shown, the first positioning surface 1211 and the first magnetic attraction portion 122 are mutually nested, so that the center of the supporting force between the first positioning surface 1211 and the second positioning surface 133 and the center of the magnetic force between the first magnetic attraction portion 122 and the second magnetic attraction portion 132 can be closer, so that the flatness of the light-emitting panel 13 can be further improved. And the supporting force between the first positioning surface 1211 and the second positioning surface 133 can be uniformly distributed around the magnetic force between the first magnetic attraction portion 122 and the second magnetic attraction portion 132, or the magnetic force between the first magnetic attraction portion 122 and the second magnetic attraction portion 132 can be uniformly distributed around the supporting force between the first positioning surface 1211 and the second positioning surface 133, so as to further improve the force uniformity of the light-emitting panel 13 at the position corresponding to each fixing component 12.

[0080] In the above embodiment, the first positioning surface 1211 and the first magnetic attraction portion 122 are mutually nested, including: the orthographic projection of the first positioning surface 1211 on the support plate 11 surrounds the orthographic projection of the first magnetic attraction portion 122 on the support plate 11, or, as Figure 4 As shown, the orthographic projection of the first magnetic attraction portion 122 on the support plate 11 surrounds the orthographic projection of the first positioning surface 1211 on the support plate 11 .

[0081] In a possible implementation, Figure 3 and Figure 4 As shown, the support column 121 includes a first part 1213 and a second part 1214 , the first part 1213 is connected to the support plate 11 , the second part 1214 is located on the end surface of the first part 1213 , and the outer diameter of the first part 1213 is greater than the outer diameter of the second part 1214 .

[0082] In the above embodiment, the support column 121 includes a first part 1213 and a second part 1214, and the first part 1213 and the second part 1214 are arranged in a direction away from the support plate 11. The first part 1213 includes two ends arranged in a direction perpendicular to the support plate 11, one end of the first part 1213 is connected to the support plate 11, and the other end of the first part 1213 is connected to the second part 1214. The second part 1214 is arranged on the end face of the first part 1213, that is, the second part 1214 is arranged on a side surface of the first part 1213 facing away from the support plate 11.

[0083] Specifically, one end of the first portion 1213 close to the support plate 11 is the first end of the support column 121 , and one end of the first portion 1213 away from the support plate 11 and the second portion 1214 are the second end of the support column 121 .

[0084] In the above implementation mode, if Figure 3 As shown, the outer diameter of the first part 1213 is greater than the outer diameter of the second part 1214 , and there is an annular area not covered by the second part 1214 on the surface of the first part 1213 facing away from the support plate 11 , i.e., an annular surface, which can be used as a supporting surface 1212 for supporting the first magnetic attraction part 122 .

[0085] Specifically, Figure 3 As shown, the central axis of the second part 1214 can coincide with the central axis of the first part 1213 , which can enhance the supporting effect of the first part 1213 on the second part 1214 and enable the above-mentioned area to be arranged around the first part 1213 .

[0086] Specifically, Figure 3 As shown, the outer diameter of the first portion 1213 may gradually decrease in a direction away from the support plate 11, thereby enhancing the support effect of the support plate 11 on the first end of the support column 121. The outer diameter of the second portion 1214 may remain constant in a direction away from the support plate 11.

[0087] In a possible implementation, Figure 3 As shown, the end surface of the second part 1214 forms a first positioning surface 1211, that is, the surface of the second part 1214 facing away from the first part 1213 forms the first positioning surface 1211, so that the first positioning surface 1211 is located at an end surface of the support column 121 away from the support plate 11, so as to achieve good support for the light-emitting panel 13.

[0088] In a possible implementation, Figure 3 As shown, the outer peripheral surface of the second part 1214 forms the support surface 1212 , and / or, the annular surface surrounding the second part 1214 in the end surface of the first part 1213 forms the support surface 1212 .

[0089] In the above embodiment, the outer peripheral surface of the second portion 1214 may form a support surface 1212 for fixing the first magnetic attraction portion 122. That is, the support surface 1212 is formed on the outer peripheral surface of the second portion 1214 and / or on a side surface of the first portion 1213 away from the support plate 11.

[0090] The outer peripheral surface of the second portion 1214 refers to the surface of the second portion 1214 that is arranged around its own central axis.

[0091] In a possible implementation, Figure 3 and Figure 4 As shown, the central axis of the first positioning surface 1211 coincides with the central axis of the first magnetic attraction portion 122 , and the central axis of the first magnetic attraction portion 122 coincides with the central axis of the second magnetic attraction portion 132 .

[0092] In the above embodiment, the first positioning surface 1211 may be a circular surface, the central axis of the first positioning surface 1211 passes through the center of the circular surface, the first magnetic attraction portion 122 may be annular or cylindrical, and the second magnetic attraction portion 132 may be annular or cylindrical. The shape of the second magnetic attraction portion 132 may be the same as that of the first magnetic attraction portion 122, so as to improve the uniformity of the magnetic force.

[0093] In the above embodiment, the central axis of the first positioning surface 1211, the central axis of the first magnetic attraction portion 122, and the central axis of the second magnetic attraction portion 132 all coincide with each other, so that the magnetic attraction force between the first magnetic attraction portion 122 and the second magnetic attraction portion 132 and the supporting force between the first positioning surface 1211 and the second positioning surface 133 are coaxial, thereby reducing the deflection moment of the light-emitting panel 13 at each position corresponding to the fixing component 12, so that the light-emitting panel 13 is not prone to local deformation while being sucked, thereby improving the problem of the light-emitting panel 13 being prone to warping at the magnetic fixing position.

[0094] In a possible implementation, Figure 7 As shown, the first portion 1213 and the second portion 1214 are integrally formed.

[0095] In the above embodiment, the first part 1213 and the second part 1214 are integrally formed to omit the assembly process, thereby improving the connection strength between the first part 1213 and the second part 1214 and improving the quality and service life of the light-emitting module 1 .

[0096] Specifically, the first portion 1213 and the second portion 1214 may be formed by a die-casting process.

[0097] Specifically, the support column 121 and the support plate 11 may be integrally formed, and the support column 121 and the support plate 11 may also be formed by a die-casting process.

[0098] In a possible implementation, Figure 3 , Figure 4 and Figure 5 As shown, the first magnetic attraction portion 122 is annular, and the first magnetic attraction portion 122 is sleeved on the outer circumference of the second portion 1214 .

[0099] In the above embodiment, the first magnetic attraction portion 122 is arranged around the first positioning surface 1211, and the first magnetic attraction portion 122 is annular and is sleeved on the outer circumferential surface of the second portion 1214, so that the magnetic force of the first magnetic attraction portion 122 can be distributed along the circumference of the first positioning surface 1211, so that the magnetic attraction force provided by the first magnetic attraction portion 122 to the light-emitting panel 13 is uniformly surrounded by the supporting force provided by the support column 121 to the light-emitting panel 13, thereby improving the force uniformity of the light-emitting panel 13 in the area corresponding to each fixing component 12, and improving the flatness of the light-emitting panel 13 after being fixed, that is, while achieving stable magnetic attraction to the light-emitting panel 13, the flatness of the light-emitting panel 13 is enhanced, and the deformation of the light-emitting panel 13 is reduced.

[0100] In a possible implementation, Figure 3 , Figure 4 and Figure 5 As shown, the first magnetic attraction portion 122 includes a first magnet 1221 , and the first magnet 1221 includes a first annular magnet.

[0101] In the above embodiment, the first magnetic attraction portion 122 may include a first magnet 1221, the first magnet 1221 may include a first annular magnet, the first annular magnet includes a first annular body 1229 and a first through hole 1230 located in the first annular body 1229, and the first through hole 1230 is used to accommodate the second part 1214, so that the first magnet 1221 is arranged on the outer periphery of the second part 1214.

[0102] Specifically, the shape of the first annular magnet may be a circular ring to enhance the uniformity of the magnetic force surrounding the second portion 1214 .

[0103] In a feasible implementation manner, the first magnet 1221 is threadedly connected to the outer circumferential surface of the second portion 1214 .

[0104] In the above embodiment, an internal thread may be formed on the side wall of the first through hole 1230 of the first magnet 1221, and an external thread may be formed on the outer peripheral surface of the second part 1214. The internal thread of the first magnet 1221 and the external thread of the second part 1214 may be threadedly connected to achieve the fixation of the first magnet 1221 and the second part 1214. In this case, the outer peripheral surface of the second part 1214 is the support surface 1212. This embodiment can simplify the connection between the first magnet 1221 and the second part 1214 on the one hand, and on the other hand, it can improve the strength of the connection and fixation and save material costs.

[0105] In another feasible implementation manner, the first magnet 1221 is bonded and fixed to the supporting surface 1212 .

[0106] In the above embodiment, the support surface 1212 is formed on the outer peripheral surface of the second part 1214 and / or the side surface of the first part 1213 facing away from the support plate 11, and the first magnet 1221 can be bonded and fixed to the outer peripheral surface of the second part 1214, and / or the first magnet 1221 can be bonded and fixed to the side surface of the first part 1213 facing away from the support plate 11.

[0107] In a possible implementation, Figures 8 to 11 As shown, the first magnetic attraction portion 122 also includes a first magnet seat 1222. Fig.10 As shown, the first magnet seat 1222 is provided with a first receiving groove 1223 for receiving the first magnet 1221 , and the first magnet 1221 is fixed in the first receiving groove 1223 .

[0108] In the above embodiment, the first magnetic attraction portion 122 further includes a first magnet seat 1222 . The first magnet seat 1222 may be ring-shaped. The first magnet seat 1222 is used to protect the first magnet 1221 .

[0109] The first magnet seat 1222 is provided with a first accommodating groove 1223 for accommodating the first magnet 1221. The first accommodating groove 1223 may be annular. The first magnet seat 1222 includes a second annular body 1231 and a second through hole 1232 located at the center of the second annular body 1231. The second annular body 1231 is formed with the first accommodating groove 1223. The first accommodating groove 1223 includes a bottom wall and an opening that are relatively arranged. The bottom wall is perpendicular to the axial direction of the second through hole 1232.

[0110] The material of the first magnet seat 1222 can be ferromagnetic material, and the first magnet 1221 can be placed inside the first receiving groove 1223 through the opening to achieve magnetic fixation with the first magnet seat 1222. Since the material of the first magnet 1221 is relatively brittle and is easily broken under the action of external force, the first magnet seat 1222 made of ferromagnetic material can protect the first magnet 1221, on the one hand, preventing the first magnet 1221 from being damaged by external force, and on the other hand, the first magnet seat 1222 is made of ferromagnetic material, which itself has no magnetism, but can be made of materials such as iron, solid, and nickel with good hardness, so that the first magnet 1221 and the first magnet seat 1222 can be fixed by magnetic attraction, and the first magnet seat 1222 is fixed to the support surface 1212, so that the first magnet 1221 and the support surface 1212 are indirectly fixed through the first magnet seat 1222, which can further reduce the damage to the first magnet 1221 caused when the first magnet 1221 and the support surface 1212 are fixed.

[0111] In a feasible implementation manner, the first magnet seat 1222 is threadedly connected to the outer peripheral surface of the second portion 1214 , or the first magnet seat 1222 is adhesively fixed to the support surface 1212 .

[0112] In the above embodiment, the surface of the first magnet seat 1222 facing the second through hole 1232 may be formed with an internal thread, the outer peripheral surface of the second part 1214 may be formed with an external thread, and the first magnet seat 1222 and the second part 1214 may be fixed by threads. Alternatively, the support surface 1212 is formed on the outer peripheral surface of the second part 1214 and / or the side surface of the first part 1213 away from the support plate 11, and the first magnet seat 1222 may be bonded and fixed to the outer peripheral surface of the second part 1214, and / or the first magnet seat 1222 may be bonded and fixed to the side surface of the first part 1213 away from the support plate 11.

[0113] The first magnet 1221 and the first magnet seat 1222 may also be fixed in other ways, such as adhesive fixation, which is not particularly limited in the present application.

[0114] In a possible implementation, Figure 4 , Figure 7 and Fig.11 As shown, the second positioning surface 133 is formed on a side surface of the body 131 facing the support plate 11 .

[0115] In the above embodiment, the second positioning surface 133 and the second magnetic attraction portion 132 are staggered.

[0116] In the above embodiment, the second positioning surface 133 is formed on the side surface of the body 131 facing the support plate 11, which can reduce the variables of the light-emitting panel 13 and the support column 121 during the positioning process, thereby improving the positioning accuracy. Specifically, in the above embodiment, the light-emitting panel 13 is supported by the support column 121, and the first positioning surface 1211 is formed on the support column 121, so the position of the first positioning surface 1211 relative to the support column 121 is fixed, and will not produce process errors due to the presence of other components, so the positioning accuracy can be improved; the second positioning surface 133 is formed on the body 131, so the second positioning surface 133 will not produce process errors due to the presence of other components, so the positioning accuracy can be further improved.

[0117] For example, compared with the positioning of the support column 121 and the light-emitting panel 13 by the first magnetic attraction part 122 and the second magnetic attraction part 132, the first magnetic attraction part 122 is fixed to the support column 121. During the fixing process, due to the limitation of the fixing accuracy, the position of the first magnetic attraction part 122 may change slightly, so that the surfaces of the side of different first magnetic attraction parts 122 away from the support plate 11 are not on the same plane, thus causing the positioning error; or, because the second magnetic attraction part 132 is fixed to the body 131, during the fixing process, due to the limitation of the fixing accuracy, the position of the second magnetic attraction part 132 may change slightly, so that the surfaces of the side of different second magnetic attraction parts 132 close to the support plate 11 are not on the same plane, thus causing the positioning error. Directly using the first positioning surface 1211 on the support column 121 and the second positioning surface 133 on the body 131 to achieve positioning reduces the above-mentioned process errors. The first positioning surface 1211 on the support column 121 can be formed by CNC machining (Computer Numerical Control) technology with high precision, and the second positioning surface 133 is formed by a grinding process with high precision. If there are multiple second positioning surfaces 133 that are not in the same plane or are poorly positioned, they can be subsequently leveled through a grinding process.

[0118] In a possible implementation, Figure 4 , Figure 7 and Fig.11 As shown, the second magnetic attraction portion 132 includes a second annular magnet, and the second annular magnet is disposed around the second positioning surface 133 .

[0119] In the above embodiment, the second magnetic attraction portion 132 includes a second annular magnet, which is arranged around the second positioning surface 133, and the second annular magnet cooperates with the first annular magnet around the second portion 1214 and is fixed by magnetic attraction. The second magnetic attraction portion 132 includes a third annular body and a third through hole 1322 located at the center of the third annular body, and the second portion 1214 extends into the third through hole 1322 of the second annular magnet and contacts the second positioning surface 133 to ensure that the second magnetic attraction portion 132 and the second portion 1214 do not interfere with each other, and support is achieved for the light-emitting panel 13, so that the first magnetic attraction portion 122 and the second magnetic attraction portion 132 are separated by a first isolation gap L1, so as to achieve magnetic attraction and fixation of the light-emitting panel 13 and the support column 121, while avoiding positioning failure caused by the second magnetic attraction portion 132 contacting the first magnetic attraction portion 122.

[0120] In the above embodiment, the second positioning surface 133 is formed on a side surface of the body 131 facing the support plate 11. Fig.12As shown, the body 131 may include a circuit board 1311 and a light emitting device 1312 located on one side of the circuit board 1311. A surface of one side of the circuit board 1311 in the body 131 away from the light emitting device 1312 faces the support plate 11.

[0121] like Fig.12 As shown, the body 131 may further include a packaging layer 1313 located on a side of the light emitting device 1312 away from the circuit board 1311 .

[0122] Specifically, when the second positioning surface 133 is formed on the body 131, it can be formed on the side surface of the circuit board 1311 facing the support plate 11. A partial area of ​​the side surface of the circuit board 1311 facing the support plate 11 can be ground to form the second positioning surface 133. Grinding a partial area of ​​the side surface of the circuit board 1311 facing the support plate 11 can control the overall thickness of the area, thereby improving the accuracy of alignment. Specifically, the side surface of the circuit board 1311 facing the support plate 11 includes a substrate layer, and a copper layer is formed on the side of the substrate layer away from the support plate 11. Grinding a partial area of ​​the side surface of the circuit board 1311 facing the support plate 11 can grind off the substrate layer to expose the copper layer.

[0123] Specifically, the first annular magnet and the second annular magnet have opposite polarities.

[0124] Alternatively, the second magnetic attraction portion 132 is made of ferromagnetic material, such as iron, cobalt, nickel, etc. The ferromagnetic material can be attracted by the first magnet 1221 .

[0125] Specifically, the second magnetic attraction portion 132 may be an annular iron sheet, which is fixed to the body 131 during the SMT (Surface Mount Technology) process of the body 131 .

[0126] In another feasible implementation manner, the first magnetic attraction portion 122 is made of ferromagnetic material, such as iron, cobalt, nickel, etc., and the second magnetic attraction portion 132 is made of a magnet.

[0127] In a possible implementation, Fig.13 As shown, the second positioning surface 133 is formed on a side surface of the second magnetic attraction portion 132 facing the supporting column 121 .

[0128] In this embodiment, the second positioning surface 133 is formed on the side surface of the second magnetic attraction portion 132 facing the support column 121. At this time, the second magnetic attraction portion 132 can be block-shaped, and the shape of the outer peripheral edge can be the same as the first magnetic attraction portion 122, that is, when the first magnetic attraction portion 122 is a circular first ring magnet, the outer peripheral edge of the second magnetic attraction portion 132 can be circular, that is, the second magnetic attraction portion 132 is cylindrical and thinner. In this embodiment, the second part 1214 contacts the second magnetic attraction part 132, and the dimension of the second part 1214 along the direction perpendicular to the support plate 11 is larger than the dimension of the first magnetic attraction part 122 along the direction perpendicular to the support plate 11, so that the side surface of the second part 1214 facing away from the support plate 11 exceeds the side surface of the first magnetic attraction part 122 facing away from the support plate 11 by a first preset distance, that is, the first positioning surface 1211 and the side surface of the first magnetic attraction part 122 facing away from the support plate 11 are spaced by a first preset distance, so that after the first positioning surface 1211 contacts the second positioning surface 133 located on the side of the second magnetic attraction part 132 facing the support plate 11, a first spacing gap is spaced between the first magnetic attraction part 122 and the second magnetic attraction part 132, so as to achieve magnetic fixation of the light-emitting panel 13 and the support column 121 while avoiding positioning failure caused by the contact between the second magnetic attraction part 132 and the first magnetic attraction part 122.

[0129] Specifically, a dimension of the first spacing gap along a direction perpendicular to the support plate 11 is the same as the first preset distance.

[0130] In the above embodiment, the second magnetic attraction portion 132 may be ground to control the thickness of the light emitting panel 13 at a position corresponding to the fixing component 12 , so as to adjust the flatness of the light emitting panel 13 .

[0131] In a feasible implementation manner, the second magnetic attraction portion 132 is fixed to the body 131 by welding and is grounded synchronously.

[0132] In this embodiment, the second magnetic attraction portion 132 can be made of metal material and can be synchronously grounded with the circuit board 1311. The support column 121 can also be made of metal material. After the first positioning surface 1211 contacts the second positioning surface 133, the support column 121 and the circuit board 1311 can be synchronously grounded, so that the support column 121 and the circuit board 1311 have good electrical conductivity, which can enhance the EMI (electromagnetic interference) performance of the entire machine.

[0133] like Fig.14 As shown, since the support column 121 and the support plate 11 can be integrally formed, the support plate 11, the support column 121 and the circuit board 1311 can be grounded synchronously to further improve the EMI (electromagnetic interference) performance of the whole machine.

[0134] In a feasible embodiment, the support column 121 includes a first portion 1213 and a plurality of second portions 1214 (not shown) corresponding to the same first portion 1213, the first portion 1213 is connected to the support plate 11, the plurality of second portions 1214 are located on the end surface of the first portion 1213, and the outer diameter of the first portion 1213 is greater than the outer diameter of the second portion 1214. The plurality of second portions 1214 are evenly distributed around the central axis of the first portion 1213. The first magnetic attraction portion 122 is annular, and the first magnetic attraction portion 122 is sleeved on the outer periphery of the plurality of second portions 1214.

[0135] Specifically, the first magnetic attraction portion 122 is bonded and fixed to the outer periphery of the second portion 1214 , or the first magnetic attraction portion 122 is bonded and fixed to a portion of the end surface of the first portion 1213 exposed by the second portion 1214 .

[0136] The first magnetic attraction portion 122 may adopt any one of the above-mentioned embodiments, and the present application does not make any special limitation thereto.

[0137] In a possible implementation, Fig.15 and Fig.16 As shown, the support column 121 includes a third part 1215 and multiple fourth parts 1216. The multiple fourth parts 1216 are distributed around the circumference of the third part 1215. The side surface of the fourth part 1216 facing away from the support plate 11 forms a first positioning surface 1211, and the side surface of the third part 1215 facing away from the support plate 11 forms a support surface 1212.

[0138] The support column 121 includes a third part 1215 and multiple fourth parts 1216. The multiple fourth parts 1216 are arranged around the circumference of the third part 1215. The side surface of the fourth part 1216 facing away from the support plate 11 is located on the side of the side surface of the third part 1215 facing away from the support plate 11, away from the support plate 11, so that the side surface of the fourth part 1216 facing away from the support plate 11 forms a first positioning surface 1211.

[0139] A surface of the third portion 1215 that is away from the support plate 11 forms a support surface 1212 , and the first magnetic attraction portion 122 and the support surface 1212 can be fixed by bonding.

[0140] In the above embodiment, the first positioning surface 1211 is circumferentially arranged around the first magnetic attraction portion 122 to improve the uniformity of the distribution of the supporting force around the magnetic attraction force, which helps to prevent the light-emitting panel 13 from being easily deformed while being fixed, thereby improving the flatness of the light-emitting panel 13 and helping to improve the display effect of the light-emitting module 1.

[0141] Specifically, the plurality of fourth portions 1216 may be distributed at intervals along the circumference of the third portion 1215 , or the plurality of fourth portions 1216 may be arranged along the circumference of the third portion 1215 and connected to each other.

[0142] In a possible implementation, Fig.15 , Fig.16 and Fig.17 As shown, in the support column 121 , a plurality of fourth portions 1216 are evenly spaced around the circumference of the third portion 1215 to improve the uniformity of the supporting force provided by the first positioning surface 1211 to the light emitting panel 13 , and further improve the flatness of the light emitting panel 13 .

[0143] In the above embodiment, the number of the fourth parts 1216 may be two, and a line connecting the centers of the two fourth parts 1216 passes through the central axis of the third part 1215 .

[0144] Alternatively, the number of fourth portions 1216 may be greater than two.

[0145] Specifically, the fourth portion 1216 may be fixed only to the third portion 1215, or a side of the fourth portion 1216 close to the third portion 1215 may be fixed to the third portion 1215, and an end of the fourth portion 1216 close to the support plate 11 may be fixed to the support plate 11. Alternatively, the fourth portion 1216 may be fixed only to the support plate 11.

[0146] When the third portion 1215 is fixed to the fourth portion 1216 , the third portion 1215 can be integrally formed with the fourth portion 1216 , thereby simplifying the assembly process and improving the fixing strength.

[0147] Specifically, the third portion 1215 , the fourth portion 1216 and the support plate 11 may be integrally formed.

[0148] Specifically, the fourth portion 1216 may have a prismatic structure or a cylindrical structure.

[0149] In a possible implementation, Fig.15 , Fig.16 and Fig.17 As shown, a groove structure 1217 is formed between the fourth portion 1216 and the third portion 1215 , and the groove structure 1217 is located at an end of the support column 121 away from the support plate 11 .

[0150] In the above embodiment, a plurality of fourth parts 1216 are enclosed between one end away from the support plate 11 to form a storage space for accommodating the first magnetic attraction part 122. The fourth part 1216 and the third part 1215 may form a groove structure 1217 at the end away from the support plate 11 to avoid the first magnetic attraction part 122, thereby increasing the capacity of the storage space.

[0151] In a feasible implementation, the first magnetic attraction portion 122 includes a second magnet 1224 , and the second magnet 1224 is bonded and fixed to the support surface 1212 ; this fixing method is simple and can reduce damage to the second magnet 1224 .

[0152] Specifically, the second magnet 1224 can adopt a sheet structure, preferably a cylindrical sheet structure, so as to improve the uniformity of the distribution of the magnetic attraction and the supporting force. The cylindrical sheet structure of the second magnet 1224 can reduce the manufacturing cost of the second magnet 1224 and facilitate installation.

[0153] Or, in another feasible implementation, as Fig.18 As shown, the first magnetic attraction portion 122 further includes a second magnet seat 1225 , the second magnet seat 1225 includes a second receiving groove 1226 , the second magnet 1224 is fixed in the second receiving groove 1226 , and the second magnet seat 1225 is bonded and fixed to the support surface 1212 .

[0154] In this embodiment, the second magnet seat 1225 can protect the second magnet 1224 , thereby reducing damage to the second magnet 1224 .

[0155] Specifically, the second magnet seat 1225 can be made of ferromagnetic material, and the second magnet 1224 can be placed inside the second receiving groove 1226 to achieve magnetic fixation with the second magnet seat 1225. Since the material of the second magnet 1224 is relatively brittle and is easily broken under the action of external force, the second magnet seat 1225 made of ferromagnetic material can protect the second magnet 1224, on the one hand, preventing the external force from causing damage to the second magnet 1224, and on the other hand, the second magnet seat 1225 is made of ferromagnetic material, which itself has no magnetism, but can be made of materials such as iron, solid, and nickel with good hardness, so that the second magnet 1224 and the second magnet seat 1225 can be fixed by magnetic attraction, and the second magnet seat 1225 is fixed to the support surface 1212, so that the second magnet 1224 and the support surface 1212 are indirectly fixed through the second magnet seat 1225, which can further reduce the damage to the second magnet 1224 caused when the second magnet 1224 and the support surface 1212 are fixed.

[0156] Specifically, when the second magnet 1224 adopts a cylindrical sheet structure, the bottom wall of the second magnet seat 1225 is also a circular sheet structure.

[0157] Alternatively, in another feasible implementation, the bottom wall of the second magnet seat 1225 is provided with a threaded column (not shown in the figure), and the end surface of the third part 1215 is provided with a threaded hole (not shown in the figure), and the threaded column is threadedly connected to the threaded hole.

[0158] In this embodiment, the second magnet seat 1225 can be directly fixed to the support surface 1212, reducing the difficulty of assembly.

[0159] In a possible implementation, Fig.17 and Fig.18 As shown, the second positioning surface 133 is formed on a side surface of the body 131 close to the support plate 11 .

[0160] In this embodiment, the second positioning surface 133 is distributed circumferentially around the second magnetic portion 132, so that the supporting force provided for the light-emitting panel 13 after the first positioning surface 1211 contacts the second positioning surface 133 is set around the magnetic force between the first magnetic portion 122 and the second magnetic portion 132, so as to improve the force uniformity of the light-emitting panel 13, thereby improving the flatness of the light-emitting panel 13.

[0161] In a possible implementation, Fig.19 and Fig. 20 As shown, the light-emitting module 1 further includes a baffle 14 , which is connected to the peripheral side of the support plate 11 , and is located on a side of the support plate 11 facing the fixing assembly 12 .

[0162] In the above embodiment, the baffle 14 is disposed around the circumference of the support plate 11 , and the baffle 14 and the support plate 11 enclose a receiving cavity, and the fixing assembly 12 is located in the receiving cavity and fixed to the support plate 11 .

[0163] The accommodating cavity may also accommodate other components, such as connecting wires used to connect adjacent light-emitting panels 13 .

[0164] In the above embodiment, the accommodating cavity accommodates the components located between the light emitting panel 13 and the supporting plate 11 , thereby improving the integrity and aesthetics of the light emitting module 1 .

[0165] In a possible implementation, Figures 19 to 21 As shown, there is a second isolation gap L2 between the light emitting panel 13 and the baffle 14 .

[0166] In the above embodiment, there is a second isolation gap L2 between the light-emitting panel 13 and the baffle 14, which means that there is a second isolation gap L2 between some surfaces of the main body 131 of the light-emitting panel 13 facing the support plate 11 and a side surface of the baffle 14 away from the support plate 11. The existence of the above second isolation gap L2 prevents the baffle 14 from contacting the light-emitting panel 13, thereby preventing the baffle 14 from lifting the light-emitting panel 13 and causing an adverse effect on the flatness of the light-emitting panel 13.

[0167] In the above embodiment, the support column 121, the baffle 14 and the support plate 11 can be integrally formed.

[0168] In the above embodiment, when the support column 121 includes the fourth portion 1216, the fourth portion 1216 can be integrally formed with the baffle 14. Specifically, Fig. 22 As shown, the fourth portion 1216 and the baffle 14 may be prepared by a die-casting process, and a portion of the fourth portion 1216 may be located within the baffle 14 to ensure a die-casting yield.

[0169] In a feasible implementation manner, a dimension of the second isolation gap L2 along a direction perpendicular to the support plate 11 is 0.3 mm to 0.5 mm.

[0170] In the above embodiment, the second isolation gap L2 should not be too large or too small. If the second isolation gap L2 is too small, it is easy for the baffle 14 to contact with the light-emitting panel 13 due to the manufacturing accuracy problem, thereby causing poor flatness of the light-emitting panel 13. If the second isolation gap L2 is too large, it is not conducive to waterproof and dustproofing in the accommodating cavity.

[0171] The second isolation gap L2 may specifically be 0.3 mm, 0.4 mm, 0.43 mm, 0.5 mm, etc.

[0172] In a possible implementation, Figure 20 to Figure 22 As shown, the support column 121, the baffle 14 and the support plate 11 have an integrated structure, which can simplify the assembly process on the one hand and improve the strength of the connection on the other hand.

[0173] In a feasible implementation manner, a dimension of the first isolation gap L1 along a direction perpendicular to the support plate 11 is 0.1 mm to 0.8 mm.

[0174] In the above embodiment, the first isolation gap L1 between the first magnetic attraction portion 122 and the second magnetic attraction portion 132 can enable the light-emitting panel 13 to be stably adsorbed on the fixing component 12 while preventing the first magnetic attraction portion 122 and the second magnetic attraction portion 132 from contacting each other and causing the light-emitting panel 13 to be lifted up, thereby helping to improve the flatness of the light-emitting panel 13.

[0175] The size of the first isolation gap L1 along the direction perpendicular to the support plate 11 may be 0.1 mm, 0.12 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.58 mm, 0.7 mm, 0.8 mm, etc.

[0176] Specifically, the first isolation gap L1 is located between the first magnetic attraction portion 122 and the second magnetic attraction portion 132, which means that it is located between the entire first magnetic attraction portion 122 and the entire second magnetic attraction portion 132. When the first magnetic attraction portion 122 includes the first magnet 1221, the first isolation gap L1 is located between the first magnet 1221 and the second magnetic attraction portion 132. When the first magnetic attraction portion 122 includes the first magnet 1221 and the first magnet seat 1222, the first isolation gap L1 is located between the first magnet 1221 and the second magnetic attraction portion 132 and between the first magnet seat 1222 and the second magnetic attraction portion 132. When the first magnetic attraction portion 122 includes the second magnet 1224 and the second magnet seat 1225, the first isolation gap L1 is located between the second magnet 1224 and the second magnetic attraction portion 132 and between the second magnet seat 1225 and the second magnetic attraction portion 132.

[0177] Specifically, the area of ​​the overlapping part of the orthographic projection of the first magnetic attraction part 122 and the second magnetic attraction part 132 on the support plate 11 can be 25 mm 2 -50mm 2 , to ensure the strength of the magnetic attraction.

[0178] Specifically, the orthographic projections of the first magnetic attraction portion 122 and the second magnetic attraction portion 132 on the support plate 11 may overlap.

[0179] The present application also provides a display device 2, such as Fig.23 As shown, it includes any one of the light-emitting modules 1 provided in the above embodiments.

[0180] Specifically, in the display device 2 , a plurality of light emitting panels 13 are spliced ​​on the same support plate 11 , and each light emitting panel 13 is fixed to the support plate 11 via a plurality of fixing components 12 , so that the display device 2 has a larger display area.

[0181] The display device 2 in the embodiment of the present application includes but is not limited to an advertising display screen, a giant screen cinema display screen, etc.

[0182] The flatness of the display surface of the display device 2 provided in the present application is significantly improved, which helps to improve the display effect and helps to improve the user experience.

[0183] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
