[0003] Medical displays and other display devices, due to their unique application requirements, usually need to have a cover plate installed on the light-emitting side of the display module to protect the display module.

[0004] In related technologies, the cover plate is usually assembled on the outer frame of the assembly module. The contact between the outer frame and the cover plate will generate a certain compressive stress on the cover plate. However, due to the inevitable manufacturing tolerances and / or assembly tolerances of structural components such as the outer frame and adapters, or because the connection between the back plate of the assembly module and / or the adapters and the outer frame will affect the flatness of the outer frame, the outer frame will generate compressive stress on the cover plate.

[0053] It should be noted that in the following embodiments of this disclosure, the definitions of "parallel" and "perpendicular" are not absolute values ​​in a mathematical sense, and a certain degree of error and fluctuation is allowed.

[0054] This disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0055] In related technologies, the cover plate 20 is usually assembled on the outer frame 100 of the assembly module. The contact between the outer frame 100 and the cover plate 20 will generate a certain compressive stress on the cover plate 20. However, due to the inevitable manufacturing tolerances and / or assembly tolerances of structural components such as the outer frame 100 and the adapter plate 310, or because the connection between the back plate 200 and / or the adapter plate 310 of the assembly module and the outer frame 100 will affect the flatness of the outer frame 100, the outer frame 100 will generate compressive stress on the cover plate 20. The compressive stress is transmitted to the display module 30, which will cause uneven stress on the display module 30 and produce yellow spots and / or light leakage defects.

[0056] To address the technical problem of yellow spots and / or light leakage defects in the display module 30 caused by the compressive stress generated by the outer frame 100 on the cover plate 20 being transmitted to the display module 30, this disclosure proposes an assembly module, as shown in Figures 1-2 and 5-10. The assembly module includes an outer frame 100, a back plate 200, and several transition components 300. The outer frame 100 includes an outer side plate 110 and an outer support plate 120 connected to the outer side plate 110. The outer support plate 120 has a first support side and a second support side disposed opposite to each other, the first support side being used to support the cover plate 20. The back plate 200 includes a rear plate 210 and a connecting plate 220 surrounding the rear plate 210. The rear plate 210 is located on the non-light-emitting side of the cover plate 20 and is spaced apart from the cover plate 20 to form a receiving cavity between the rear plate 210 and the cover plate 20. The transition components 300 include a transfer plate and at least one... The elastic buffer 320 and the adapter plate 310 include a first adapter portion 311 and a second adapter portion 312 connected to the first adapter portion 311. The first adapter portion 311 is used to connect to the connecting plate 220, and the second adapter portion 312 is used to connect to the outer support plate 120 and is located on the second support side of the outer support plate 120. The elastic buffer 320 is elastically supported between the second adapter portion 312 and the second support side and / or the elastic buffer 320 is elastically supported between the first adapter portion 311 and the connecting plate 220.

[0057] The assembly module proposed in this embodiment, as shown in Figures 1 to 2 and Figures 5 to 10, involves the outer frame 100 and the back panel 200 connected by several transition components 300. By elastically supporting the elastic buffer 320 in the transition component 300 between the second transition portion 312 and the second support side, and / or elastically supporting the elastic buffer 320 between the first transition portion 311 and the connecting plate 220, the deformation of the elastic buffer 320 can offset manufacturing and assembly errors and absorb compressive stress. This, to a certain extent, prevents the transmission of compressive stress to the display module 30, thereby achieving a certain degree of... To avoid yellow spots and / or light leakage defects in the display module 30 due to uneven stress; on the other hand, the outer frame 100 and the back plate 200 are connected by several adapter components 300. The adapter components 300 not only have the characteristics of small structure, but also are independent of the outer frame 100 and the back plate 200 and the installation position is adjustable. Different sizes of assembly modules can be connected by different numbers of adapter components 300, which can improve the versatility and compatibility of the adapter components 300, so that the adapter components 300 can be applied to assembly modules of different sizes, which can reduce the cost of assembly modules and display devices to a certain extent.

[0058] In some embodiments of this disclosure, as shown in Figures 1 to 2 and Figures 5 to 10, the first support side of the outer support plate 120 of the outer frame 100 is used to support the cover plate 20. It is necessary to ensure the flatness of the first support side so that the first support side fits with the four edges of the cover plate 20, thereby avoiding the cover plate 20 from being subjected to compressive stress and affecting the display module 30. In this way, it can be avoided that the display module 30 will produce yellow spots and / or light leakage defects due to uneven force.

[0059] In related technologies, although there are technical solutions that adjust the relative position between the outer frame 100 and the back plate 200 by adjusting the height of connecting parts such as screws, thereby adjusting the flatness of the mating surface between the outer frame 100 and the cover plate 20, such technical solutions require the adjustment of connecting parts such as screws. On the one hand, a large number of connecting parts such as screws need to be manually adjusted, which is not convenient. On the other hand, during the adjustment process, there is not only a risk of transmitting compressive stress to the cover plate 20 and the display module 30, but also the introduction of adjustment errors. Therefore, it cannot effectively ensure the flatness of the mating surface between the outer frame 100 and the cover plate 20, or solve the yellow spots and / or light leakage defects caused by uneven stress on the display module 30.

[0060] In the assembly module, the outer frame 100 also needs to be connected to the back plate 200. If the outer frame 100 and the back plate 200 are directly connected by screws or other connectors, a rigid connection is formed between the outer frame 100 and the back plate 200. When there are manufacturing or assembly tolerances in the outer frame 100 and / or the back plate 200, compressive stress will be generated, which will affect the flatness of the first support side. This will cause the first support side to not be able to fully fit with the four edges of the cover plate 20, resulting in yellow spots and / or light leakage defects in the display module 30. If the outer frame 100 and the back plate 200 are respectively connected to the adapter plate 310 by screws or other connectors to form the outer frame 100 The structure indirectly connected to the back panel 200 via the adapter plate 310 will also form a rigid connection between the outer frame 100 and the back panel 200. If there are manufacturing tolerances in any one or more of the outer frame 100, the back panel 200 and the adapter plate 310, or if there are assembly tolerances between the outer frame 100, the back panel 200 and the adapter plate 310, extrusion stress will be generated, which will affect the flatness of the first support side. This will cause the first support side to not be able to fit completely with the four edges of the cover plate 20, and will transfer the extrusion stress to the display module 30, which will cause the display module 30 to produce yellow spots and / or light leakage defects due to uneven stress. When the outer frame 100 and the back panel 200 are connected via the adapter plate 310, i.e., the outer support plate 120 of the outer frame 100 is connected to the second adapter portion 312 of the adapter plate 310, and the connecting plate 220 of the back panel 200 is connected to the first adapter portion 311 of the adapter plate 310, since there is an assembly angle between the outer support plate 120 and the connecting plate 220, the manufacturing angle between the first adapter portion 311 and the second adapter portion 312 and the assembly angle between the outer support plate 120 and the connecting plate 220 need to be matched. However, in practice, due to the existence of manufacturing tolerances and assembly tolerances, the manufacturing angle between the first adapter portion 311 and the second adapter portion 312 and the assembly angle between the outer support plate 120 and the connecting plate 220 often do not match. For example, if the assembly angle between the outer support plate 120 and the connecting plate 220 is 90°, then the manufacturing angle between the first transition part 311 and the second transition part 312 should also be 90°. However, due to manufacturing tolerances, in practice, the assembly angle between the outer support plate 120 and the connecting plate 220, and the manufacturing angle between the first transition part 311 and the second transition part 312, are often not exactly 90°. They generally fluctuate within the range of 90°±1°. When the transition plate 310 is connected to the outer support plate 120, the difference between the manufacturing angle and the assembly angle of the transition plate 310 will cause the transition plate 310 to cause the outer support plate 120 to rotate at an angle, thereby affecting the flatness of the first support side of the outer support plate 120 and generating a certain compressive stress. The compressive stress is transmitted to the display module 30 through the cover plate 20, which will lead to defects such as light leakage and / or yellow spots. Studies have found that the change in the manufacturing angle of the transition plate 310 is the main cause of light leakage in the display device.As shown in Figure 3, assuming the assembly angle between the outer support plate 120 and the connecting plate 220 is 90°, if the manufacturing tolerance of the adapter plate 310 causes the manufacturing angle between the first adapter part 311 and the second adapter part 312 to be greater than 90°, then after the outer frame 100 and the back plate 200 are connected through the adapter plate 310, the part of the first adapter part 311 near the outer side plate 110 will generate a large compressive stress on the outer support plate 120, causing the outer support plate 120 to deform and affecting the fit between the outer support plate 120 and the edge of the cover plate 20. At the same time, the compressive stress will also be transmitted to the display module 30, causing the display module 30 to produce yellow spots and / or light leakage defects due to uneven stress. As shown in Figure 4, assuming the assembly angle between the outer support plate 120 and the connecting plate 220 is 90°, if the manufacturing tolerance of the adapter plate 310 causes the manufacturing angle between the first adapter part 311 and the second adapter part 312 to be less than 90°, then after the outer frame 100 and the back plate 200 are connected through the adapter plate 310, the part of the first adapter part 311 near the connecting plate 220 will generate a large compressive stress on the outer support plate 120, causing the outer support plate 120 to deform and affecting the fit between the outer support plate 120 and the edge of the cover plate 20. At the same time, the compressive stress will also be transmitted to the display module 30, causing the display module 30 to produce yellow spots and / or light leakage defects due to uneven stress.

[0061] In some embodiments of this disclosure, as shown in Figures 1 to 2 and Figures 5 to 10, by elastically supporting the elastic buffer 320 between the second transition portion 312 and the second support side and / or elastically supporting the elastic buffer 320 between the first transition portion 311 and the connecting plate 220, on the one hand, the deformation of the elastic buffer 320 can offset the angular difference between the assembly angle and the manufacturing angle, so that the sizes of the assembly angle and the manufacturing angle match. Then, after the outer frame 100 and the back plate 200 are connected by the transition assembly 300, the flatness of the outer support plate 120 can be ensured. On the other hand, the elastic buffer 320 can buffer the compressive stress, and the transition plate 310 will not generate compressive stress on the outer support plate 120. This allows the first support side of the outer support plate 120 to fit with the edge of the cover plate 20, preventing the compressive stress from being transmitted to the display module 30 through the outer support plate 120 and the cover plate 20. This, to a certain extent, achieves the purpose of avoiding yellow spots and / or light leakage defects in the display module 30 due to uneven force.

[0062] In some embodiments of this disclosure, the adapter assembly 300 may include an adapter plate and an elastic buffer 320. The elastic buffer 320 may be disposed between the second adapter portion 312 and the second support side, or the elastic buffer 320 may also be disposed between the first adapter portion 311 and the connecting plate 220.

[0063] In some embodiments of this disclosure, the adapter assembly 300 may further include a transition plate and a plurality of elastic buffers 320. The plurality of elastic buffers 320 may all be disposed between the second adapter portion 312 and the second support side, or the plurality of elastic buffers 320 may all be disposed between the first adapter portion 311 and the connecting plate 220, or the plurality of elastic buffers 320 may be disposed between the second adapter portion 312 and the second support side, and between the first adapter portion 311 and the connecting plate 220, respectively.

[0064] In some embodiments of this disclosure, optionally, the assembly module can select an appropriate number of adapter components 300 according to its own size, so that the adapter components 300 can be evenly distributed on the connection path between the outer frame 100 and the back plate 200 of the assembly module, so as to ensure that the force on the assembly module is balanced after assembly.

[0065] In some embodiments of this disclosure, the cover plate 20 can be a glass cover plate 20. When the display device is used in medical settings such as operating rooms, the display device needs to be frequently disinfected and wiped, so the glass cover plate 20 can protect the internal components of the display device.

Furthermore, the top side, the ground side, the left side, and the right side can also adopt a common design, so that the outer frame 100 can be extruded using a set of aluminum extrusion molds, thereby reducing product costs.

The second adapter portion 312 of the adapter plate 310 is provided with a second connecting hole 3122, and the outer support plate 120 of the outer frame 100 is provided with a second fixing hole 1222. The second connector 332 can be a screw or other commonly used connector in the art. The second connector 332 is provided in the second connecting hole 3122 and the second fixing hole 1222 to connect the second adapter portion 312 and the outer support plate 120 together.

[0070] In some embodiments of this disclosure, the adapter assembly 300 may optionally include an adapter plate 310 and an elastic buffer 320, the elastic buffer 320 being elastically supported between the second adapter portion 312 and the second support side, and the center of the elastic buffer 320 may coincide with the center of the second connection hole 3122, so as to provide a balanced elastic support and buffering effect through the elastic buffer 320.

The two elastic buffers 320 are elastically supported between the second adapter portion 312 and the second support side, and the two elastic buffers 320 are located on opposite sides of the second connection hole 3122, so as to provide a balanced elastic support and buffering effect through the elastic buffers 320.

[0072] In some embodiments of this disclosure, optionally, as shown in Figures 9 and 10, the second fixing hole 1222 can be a blind hole. The elastic buffer 320 is elastically supported between the second transition portion 312 and the second support side. The thickness of the second transition portion 312, the maximum compressible dimension of the elastic buffer 320 in the thickness direction of the second transition portion 312, the length of the second connector 332, and the depth of the second fixing hole 1222 can be comprehensively considered and determined so that after the second connector 332 passes through the second connecting hole 3122 of the second transition portion 312 and connects to the second fixing hole 1222, the elastic buffer 320 can be compressed to a certain extent so that the deformation of the elastic buffer 320 after compression can offset the difference between the manufacturing angle and the assembly angle of the transition plate 310 and absorb the stress caused by the difference between the manufacturing angle and the assembly angle. Meanwhile, since the design comprehensively considers the thickness of the second adapter 312, the maximum compressible dimension of the elastic buffer 320 in the thickness direction of the second adapter 312, the length of the second connector 332, and the depth of the second fixing hole 1222, when assembling the second connector 332, there is no need to consider the depth to which the second connector 332 is screwed into the second fixing hole 1222. The second connector 332 can be directly screwed into the bottom of the second fixing hole 1222, thereby greatly reducing the assembly difficulty and improving the assembly accuracy. Optionally, after the second adapter 312 and the outer support plate 120 are connected by the second connector 332, the elastic buffer 320 is compressed to a certain extent to ensure that the elastic buffer 320 has a certain supporting force. Optionally, after the second adapter 312 is connected to the outer support plate 120 via the second connector 332, the elastic buffer 320 is compressed to a certain extent and can be further compressed. That is, at this time, the compression amount of the elastic buffer 320 is less than the maximum compressibility of the elastic buffer 320, so as to avoid the elastic buffer 320 being over-compressed and unable to rebound, and to ensure that the elastic buffer 320 can provide a certain support force.

[0073] As an optional implementation, as shown in Figures 5 to 7 and Figure 11, the inner diameter of the first connecting hole 3111 is larger than the outer diameter of the first connector 331. When the adapter plate 310 is fastened by passing through the first connecting hole 3111 via the first connector 331, space is reserved for the adapter plate 310 to move. That is, the adapter plate 310 can move to a certain extent in the length and width directions of the connecting plate 220, thereby further reducing the stress generated after fastening by the connecting assembly 330.

[0074] As an optional implementation, as shown in Figures 5 to 7 and Figure 11, the dimension of the first connecting hole 3111 in the length direction of the connecting plate 220 is smaller than the dimension of the first connecting hole 3111 in the height direction of the connecting plate 220. That is, the first connecting hole 3111 is waist-shaped, which reserves space for the adapter plate 310 to move. In other words, the adapter plate 310 can move to a certain extent in the height direction of the connecting plate 220, thereby realizing the height adjustment of the installation position of the adapter plate 310 on the connecting plate 220 and reducing the stress generated after being locked by the connecting component 330.

[0075] As an optional implementation, as shown in Figures 5 to 7 and Figure 11, the inner diameter of the second connecting hole 3122 is larger than the outer diameter of the second connector 332. When the adapter plate 310 is fastened by passing through the second connecting hole 3122 via the second connector 332, space is reserved for the adapter plate 310 to move. That is, the adapter plate 310 can move to a certain extent in the length and width directions of the outer support plate 120, thereby further reducing the stress generated after fastening by the connecting assembly 330.

[0076] As an optional implementation, as shown in Figures 5 to 7 and Figure 11, the second connecting hole 3122 is larger in the length direction of the outer support plate 120 than the second connecting hole is larger in the width direction of the outer support plate 120. That is, the second connecting hole 3122 is waist-shaped, which provides space for the adapter plate 310 to move. In other words, the adapter plate 310 can move to a certain extent in the length direction of the outer support plate 120, thereby further reducing the stress generated after being fastened by the connecting assembly 330.

[0077] As an alternative implementation, as shown in Figures 1 to 2 and Figures 5 to 10, the cross-section of the adapter plate 310 is L-shaped.

[0078] In some embodiments of this disclosure, as shown in Figures 1 to 2 and Figures 5 to 10, the cross-section of the adapter plate 310 is L-shaped, that is, there is only one manufacturing angle between the first adapter portion 311 and the second adapter portion 312. This can reduce the number of bends in the manufacturing process of the adapter plate 310, further reduce the stress caused by manufacturing errors due to the manufacturing angle formed by bending, and further reduce the risk of yellow spots and / or light leakage in the display module 30 due to uneven stress.

[0079] As an optional implementation, as shown in Figures 5 to 9, the elastic buffer 320 includes a connecting portion 321 and an elastic contact portion 322 connected to the connecting portion 321. The connecting portion 321 is used to connect to the second adapter portion 312, and the free end of the elastic contact portion 322 is used to abut against the second support side, and the included angle between the elastic contact portion 322 and the second adapter portion 312 is less than 90°.

[0080] In some embodiments of this disclosure, as shown in Figures 5 to 9, the free end of the elastic contact portion 322 is used to abut against the second support side, that is, the free end of the elastic contact portion 322 is a contact point that abuts against the second support side and forms a point contact with the second support side; by making the included angle between the elastic contact portion 322 and the second transition portion 312 less than 90°, when the second transition portion 312 is locked to the outer support plate 120 by the second connector 332, since the included angle between the elastic contact portion 322 and the second transition portion 312 is less than 90°, the free end of the elastic contact portion 322 can be subjected to a force that can generate a component parallel to the second support side, so that the elastic contact portion... The free end of 322 can slide relative to the human support side, thereby allowing the elastic contact portion 322 to be compressed and bent relative to the second transition portion 312 and form a rebound angle, generating a rebound force. This rebound force provides elastic support between the second transition portion 312 and the second support side. At the same time, since the free end of the elastic contact portion 322 is in point contact with the second support side, during the compression and bending process of the elastic contact portion 322 relative to the second transition portion 312, the free end of the elastic contact portion 322 can slide relative to the second support side with low resistance, which will not affect the compression and bending process of the elastic contact portion 322 relative to the second transition portion 312.

[0081] In some embodiments of this disclosure, as shown in Figures 5 to 9, optionally, the angle between the elastic contact portion 322 and the second transition portion 312 can be [30°, 90°], that is, the angle between the elastic contact portion 322 and the second transition portion 312 is greater than or equal to 30° and less than 90°. More optionally, the angle between the elastic contact portion 322 and the second transition portion 312 can be [45°, 75°], that is, the angle between the elastic contact portion 322 and the second transition portion 312 is greater than or equal to 45° and less than or equal to 75°. By making the angle between the elastic contact portion 322 and the second transition portion 312 greater than or equal to 30°, it is ensured that the elastic contact portion 322 can provide sufficient elastic force. If the angle between the elastic contact portion 322 and the second transition portion 312 is too small, the elastic force generated by the elastic contact portion 322 will be small, which will affect the stability and reliability of the connection between the second transition portion 312 and the outer support plate 120. In some embodiments, the included angle between the elastic contact portion 322 and the second transition portion 312 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0082] As an optional implementation, as shown in Figures 5, 8 and 9, the free end of the elastic contact portion 322 is provided with a flange 3221 or an arc-shaped surface, so that the surface of the free end of the elastic contact portion 322 that abuts against the second support side is arc-shaped.

[0083] In some embodiments of this disclosure, as shown in Figures 5, 8 and 9, the free end of the elastic contact portion 322 is provided with a flange 3221. The flange 3221 structure can make the free end of the elastic contact portion 322 have an arc-shaped surface, thereby making the surface of the free end of the elastic contact portion 322 that abuts against the second support side arc-shaped. This allows the free end of the elastic contact portion 322 to make point contact with the second support side and slide relative to the second support side, reducing the frictional resistance of sliding.

[0084] As an alternative implementation, as shown in FIG5, the elastic buffer 320 and the second adapter 312 are integrally formed, and the elastic contact part 322 is formed by bending a portion of the second adapter 312 or by cutting and bending a portion of the second adapter 312.

[0085] In some embodiments of this disclosure, as shown in FIG5, the elastic buffer 320 and the second transition portion 312 are integrally formed. The elastic buffer 320 can be formed by cutting a portion of the second transition portion 312 and bending that portion relative to the second transition portion 312 at a certain angle. Optionally, the cutting position on the second transition portion 312 can be located in the inner region of the second transition portion 312 or in the edge region of the second transition portion 312. It should be noted that, in order to make the rebound force generated by the elastic buffer 320 more uniform, the elastic buffer 320 is at least axially symmetrically distributed on the second transition plate 310.

[0086] In some embodiments of this disclosure, the elastic buffer 320 and the second adapter 312 are integrally formed. The elastic buffer 320 can be formed by bending a portion of the second adapter 312 at a certain angle relative to the second adapter 312. For example, the elastic buffer 320 can be formed by bending the second adapter 312 at the edge regions of opposite ends in the length direction of the outer support plate 120.

[0087] In some embodiments of this disclosure, optionally, as shown in FIG5, the elastic buffer 320 is formed by cutting a portion of the second transition portion 312. During the preparation process, a rectangular area can be cut out at a preset position of the second transition portion 312 as the elastic buffer 320, and one side of the rectangular area is kept connected to the second transition portion 312. Then, the cut rectangular area is bent toward the second transition portion 312 toward the outer support plate 120, thereby forming an elastic buffer 320 integral with the second transition portion 312. At the same time, the side / area that remains connected to the second transition portion 312 after the rectangular area is bent is the connecting portion 321, and the other areas of the rectangular area after bending are peripheral elastic contact portions 322. The end of the elastic contact portion 322 away from the second transition portion 312 is the free end of the elastic contact portion 322, which is used to abut against the second support side of the outer support plate 120. Optionally, the free end of the elastic contact portion 322 is provided with a flange 3221, so that the surface of the free end of the elastic contact portion 322 abutting against the second support side is arc-shaped. Optionally, the flange 3221 can be formed by bending the free end of the elastic contact portion 322. In the embodiment shown in FIG. 5, the second adapter portion 312 is provided with two elastic buffers 320, which are positioned opposite each other on both sides of the second connecting hole 3122. When the second adapter portion 312 of the adapter plate 310 is connected to the second support side of the outer support plate 120, the elastic buffer 320 is located between the second adapter portion 312 and the outer support plate 120. When the second connector 332 passes through the second connecting hole 3122 and is connected to the second fixing hole 1222 on the outer support plate 120, the elastic buffer 320 can be compressed to deform in order to offset the difference between the manufacturing angle and the assembly angle of the adapter plate 310 and absorb the stress caused by the difference between the manufacturing angle and the assembly angle.

[0088] As an optional implementation, as shown in Figures 6 to 8, the second adapter 312 has a buffer mounting hole 3121; the connecting part 321 includes a first spring arm 3211, a second spring arm 3212 opposite to the first spring arm 3211, a first support arm 3213 connected to the first spring arm 3211, a second support arm 3214 connected to the second spring arm 3212, and a connecting arm 3215 connecting the first spring arm 3211 and the second spring arm 3212. The connecting arm 3215 has a springback bend 32151. The first support arm 3213 and the second support arm 3214 are in the springback upward length of the first spring arm 3211 and the second spring arm 3212. The length of the buffer mounting hole 3121 is greater than the length of the first rebound arm 3211 and the second rebound arm 3212 in the rebound direction; the elastic contact part 322 includes a first elastic contact arm 3222 and a second elastic contact arm 3223, the first elastic contact arm 3222 is connected to the first support arm 3213, and the second elastic contact arm 3223 is connected to the second support arm 3214; the first rebound arm 3211 and the second rebound arm 3212 are used to pass through the buffer mounting hole 3121 and are engaged in the buffer mounting hole 3121 under the elastic force of the rebound bending 32151, and the first support arm 3213 and the second support arm 3214 are located on the side of the second adapter part 312 near the second support side.

[0089] In some embodiments of this disclosure, as shown in Figures 6 to 8, the first spring arm 3211 and the second spring arm 3212 are arranged opposite to each other and connected by a connecting arm 3215. A spring-loaded bend 32151 is provided on the connecting arm 3215. By compressing the first spring arm 3211 and the second spring arm 3212, the distance between the first spring arm 3211 and the second spring arm 3212 can be reduced, thereby allowing the connecting portion 321, composed of the first spring arm 3211, the second spring arm 3212, and the connecting arm 3215, to be positioned... Within the buffer mounting hole 3121 on the second adapter 312; the force pressing on the first spring arm 3211 and the second spring arm 3212 is removed. Under the elastic force of the spring bending 32151, the first spring arm 3211 and the second spring arm 3212 move in opposite directions, so that the first spring arm 3211 and the second spring arm 3212 can rebound under the elastic force of the spring bending 32151 and lock into the buffer mounting hole 3121, thereby achieving the purpose of connecting the elastic buffer 320 to the second adapter 312. The first rebound arm 3211 is also connected to the first support arm 3213, and the second rebound arm 3212 is also connected to the second support arm 3214. This allows the first support arm and the second support arm 3214 to be positioned opposite each other. When the first rebound arm 3211 and the second rebound arm 3212 are engaged in the buffer mounting hole 3121, the first support arm 3213 and the second support arm 3214 can be located on the side of the second adapter 312 closer to the second support side. Furthermore, because the upward rebound length of the first support arm 3213 and the second support arm 3214 of the first support arm 3211 and the second rebound arm 3212 is greater than the buffer mounting hole 3121... The length of hole 3121 in the rebound direction of the first rebound arm 3211 and the second rebound arm 3212 is such that the elastic buffer 320 will not pass through the buffer mounting hole 3121 at the positions of the first support arm 3213 and the second support arm 3214. Simultaneously, the first support arm 3213 is also connected to the first elastic contact arm 3222, and the second support arm 3214 is also connected to the second elastic contact arm 3223. This allows the first elastic contact arm 3222 and the second elastic contact arm 3223 to be positioned opposite each other, and the first elastic contact arm 3222 and the second contact arm are also located on the side of the second adapter 312 closer to the second support side. After the elastic buffer 320 is connected to the second adapter 312 via the connecting part 321, it forms an adapter assembly 300.

[0090] In some embodiments of this disclosure, as shown in Figures 6 to 8, a second connecting hole 3122 is provided on the second adapter 312, and buffer mounting holes 3121 are respectively provided on the opposite sides of the second connecting hole 3122. Two elastic buffers 320 are connected to the second adapter 312 through the two buffer mounting holes 3121 in a one-to-one correspondence, thus forming the adapter assembly 300 shown in Figure 6.

[0091] In some embodiments of this disclosure, as shown in Figures 2 and 6 to 9, when the second adapter 312 is assembled with the second support side of the outer support plate 120, the first support arm 3213, the second support arm 3214, the first elastic contact arm 3222, and the second elastic contact arm 3223 are located on the side of the second adapter 312 facing the outer support plate 120, that is, the first support arm 3213, the second support arm 3214, the first elastic contact arm 3222, and the second elastic contact arm 3223 are located between the second adapter 312 and the second support side. When the second connector 332 passes through the second connecting hole 3122 and connects to the second fixing hole 1222 on the outer support plate 120, the free ends of the first elastic contact arm 3222 and the second elastic contact arm 3223 abut against the second support side and are squeezed to produce a certain deformation. At the same time, the rebound force generated by the first elastic contact arm 3222 and the second elastic contact arm 3223 reacts to the second adapter 312, which can make the first support arm 3213 and the second support arm 3214 abut against the second adapter 312. That is, the two ends of the first elastic contact arm 3222 are compressed by the first support arm 3213 and the free end of the first elastic contact arm 3222 respectively, which reduces the angle between the first elastic contact arm 3222 and the first support arm 3213 and generates a rebound force. The two ends of the second elastic contact arm 3223 are compressed by the second support arm 3214 and the free end of the second elastic contact arm 3223 respectively, which reduces the angle between the second elastic contact arm 3223 and the second support arm 3214 and generates a rebound force. Thus, the deformation caused by the change in the angle between the first elastic contact arm 3222 and the first support arm 3213 and the angle between the second elastic contact arm 3223 and the second support arm 3214 can offset the difference between the manufacturing angle and the assembly angle of the adapter plate 310 and absorb the stress caused by the difference between the manufacturing angle and the assembly angle.

[0092] In some embodiments of this disclosure, optionally, as shown in Figures 2, 6 to 9, the connecting arm 3215 is connected to the end of the first spring arm 3211 away from the first support arm 3213 and the end of the second spring arm 3212 away from the second support arm 3214.

[0093] In some embodiments of this disclosure, optionally, as shown in Figures 2, 6 to 9, when the connecting arm 3215 is connected to the end of the first rebound arm 3211 away from the first support arm 3213 and the end of the second rebound arm 3212 away from the second support arm 3214, the rebound bend 32151 of the connecting arm 3215 can be oriented towards the second support side, thereby reducing the space occupied by the elastic buffer 320 in the thickness direction of the second transition portion 312.

[0094] In some other embodiments of this disclosure, the connecting arm 3215 may optionally be connected to other positions of the first spring arm 3211 and the second spring arm 3212. For example, the connecting arm 3215 may be connected to the middle region of the first spring arm 3211 and the middle region of the second spring arm 3212; in this case, the springback bend 32151 of the connecting arm 3215 may be towards the second support side, or the springback bend 32151 of the connecting arm 3215 may be away from the second support side. In this case, the direction of the springback bend 32151 of the connecting arm 3215 will not affect the space occupied by the elastic buffer 320 in the thickness direction of the second transition portion 312. For example, the connecting arm 3215 can be connected to the end of the first spring arm 3211 near the first support arm and the end of the second spring arm 3212 near the second support arm 3214. In this case, the spring bending direction of the connecting arm 3215 is preferably away from the second support side, so as to avoid interference between the spring bending 32151 and the first support arm 3213, the second support arm 3214, the first elastic contact arm 3222 and the second elastic contact arm 3223.

[0095] As an optional implementation, as shown in Figure 8, the bending angle of the springback bend 32151 is greater than or equal to 90°.

[0096] In some embodiments of this disclosure, as shown in FIG8, the first spring arm 3211 and the second spring arm 3212 generate a springback force through the springback bend 32151 of the connecting arm 3215. By making the bending angle of the springback bend 32151 greater than or equal to 90°, it can be ensured that a large springback force is generated through the springback bend 32151 of the connecting arm 3215, causing the first spring arm 3211 and the second spring arm 3212 to spring back. If the bending angle of the springback bend 32151 is too small, after the first spring arm 3211 and the second spring arm 3212 are squeezed and placed in the buffer mounting hole 3121 on the second adapter 312, the connecting arm 3215 is easily compressed and deformed and cannot spring back.

[0097] In some embodiments of this disclosure, optionally, as shown in FIG8, the bending angle of the springback bend 32151 can be [90°, 180°), that is, the bending angle of the springback bend 32151 can be greater than or equal to 90° and less than 180°. Further optionally, the bending angle of the springback bend 32151 can be [105°, 165°], that is, the bending angle of the springback bend 32151 can be greater than or equal to 105° and less than or equal to 165°. By making the bending angle of the springback bend 32151 greater than or equal to 90°, it can be ensured that the connecting arm 3215 generates sufficient springback force; at the same time, by making the bending angle of the springback bend 32151 less than 180°, it can be ensured that the connecting arm 3215 deforms at the springback bend 32151 to generate springback force. In some embodiments, the bending angle of the springback bend 32151 can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 155°, 150°, 155°, 160°, 165°, 170°, 175°, etc.

[0098] As an optional implementation, as shown in Figures 2, 6 to 9, the first elastic contact arm 3222 is bent relative to the first support arm 3213 toward the second elastic contact arm 3223, and the second elastic contact arm 3223 is bent relative to the second support arm 3214 toward the first elastic contact arm 3222.

[0099] In some embodiments of this disclosure, as shown in Figures 2 and 6 to 9, by bending the first elastic contact arm 3222 relative to the first support arm 3213 towards the second elastic contact arm 3223, and bending the second elastic contact arm 3223 relative to the second support arm 3214 towards the first elastic contact arm 3222, on the one hand, the space occupied by the first elastic contact arm 3222 and the second elastic contact arm 3223 in the upward rebound of the first rebound arm 3211 and the second rebound arm 3212 can be reduced, thereby facilitating the installation of the elastic buffer 320; on the other hand, when the elastic buffer 320 is compressed, the first elastic contact arm 3222 and the second elastic contact arm 3223 move towards each other, which can prevent the first elastic contact arm 3222 and the second elastic contact arm 3223 from increasing the space occupied by the first elastic contact arm 3222 and the second elastic contact arm 3223 in the upward rebound of the first rebound arm 3211 and the second rebound arm 3212 and interfering with adjacent structures.

[0100] As an optional implementation, as shown in Figures 2, 6 to 9, the first support arm 3213 is in surface contact with the second support side, and the second support arm 3214 is in surface contact with the second support side.

[0101] In some embodiments of this disclosure, as shown in Figures 2 and 6 to 9, by making the first support arm 3213 and the second support side in surface contact, and the second support arm 3214 in surface contact with the second support side, after the second transition portion 312 is connected to the outer support plate 120, the first support arm 3213 and the second support side can be fitted together, increasing the force-bearing area of ​​the second transition portion 312 and making the force on the second transition portion 312 more balanced. Optionally, the first support arm 3213 and the second support arm 3214 are parallel to the second support side, thereby allowing the first support arm 3213 and the second support arm 3214 to fit better with the second support side.

[0102] As an optional implementation, as shown in FIG8, the first rebound arm 3211 has a first anti-detachment protrusion 3216 at the end away from the first support arm 3213; the second rebound arm 3212 has a second anti-detachment protrusion 3217 at the end away from the second support arm 3214.

[0103] In some embodiments of this disclosure, as shown in FIG8, by providing a first anti-detachment protrusion 3216 at one end of the first rebound arm 3211 away from the first support arm 3213, and providing a second anti-detachment protrusion 3217 at one end of the second rebound arm 3212 away from the second support arm 3214, the first anti-detachment protrusion 3216 and the second anti-detachment protrusion 3217 can be arranged opposite to each other. The first anti-detachment protrusion 3216 and the second anti-detachment protrusion 3217 can, to a certain extent, prevent the elastic buffer 320 from falling off the second adapter 312.

[0104] As an optional implementation, the connecting plate 220 is provided with a first positioning protrusion 221 or a first positioning groove on the side facing the first adapter 311 for positioning the first adapter 311; and / or, the outer support plate 120 is provided with a second positioning protrusion 1221 or a second positioning groove on the second support side for positioning the second adapter 312.

[0105] In some embodiments of this disclosure, optionally, the connecting plate 220 is provided with a first positioning protrusion 221 or a first positioning groove on the side facing the first adapter 311. The first positioning protrusion 221 or the first positioning groove is used for positioning connection between the connecting plate 220 and the first adapter 311 to ensure that the back plate 200 and the backlight module 40 mounted on the back plate 200 are placed in the designated position without positional offset.

[0106] In some embodiments of this disclosure, optionally, the outer support plate 120 is provided with a second positioning protrusion 1221 or a second positioning groove on the second support side. The second positioning protrusion 1221 or the second positioning groove is used for positioning connection between the outer support plate 120 and the second adapter 312, so that the relative position of the outer frame 100, the adapter plate 310, and the back plate 200 is determined, thereby reducing assembly errors. At the same time, the second positioning protrusion 1221 and the second positioning groove can also prevent the adapter plate 310 from twisting during assembly.

[0107] In some embodiments of this disclosure, optionally, as shown in FIG2, the connecting plate 220 has a first positioning protrusion 221 on the side facing the first adapter 311. When the back plate 200 is connected to the first adapter 311, the first positioning protrusion 221 can abut against the side of the first connecting portion 321 to determine the relative position of the back plate 200 and the first adapter 311. Optionally, the first connecting portion 321 may also have a first positioning notch that matches the first positioning protrusion 221.

[0108] In some embodiments of this disclosure, optionally, the connecting plate 220 is provided with a first positioning groove on the side facing the first adapter 311. When the back plate 200 is connected to the first adapter 311, the first adapter 311 can be placed in the first positioning groove to achieve the positioning connection between the first adapter 311 and the connecting plate 220.

[0109] In some embodiments of this disclosure, optionally as shown in Figures 13 and 14, the outer support plate 120 is provided with a second positioning protrusion 1221 on the second support side. When the outer support plate 120 is connected to the second adapter 312, the second positioning protrusion 1221 can abut against the side of the second adapter 312 or the side of the elastic buffer 320 on the second adapter 312 to determine the connection position between the outer support plate 120 and the second adapter 312, and can prevent the adapter plate 310 from twisting during assembly.

[0110] In some embodiments of this disclosure, optionally, the outer support plate 120 is provided with a second positioning groove on the second support side. When the outer support plate 120 is connected to the second adapter 312, the second adapter 312 can be placed in the second positioning groove to realize the connection position between the outer support plate 120 and the second adapter 312, and at the same time, it can also prevent the adapter plate 310 from twisting during assembly.

[0111] As an optional implementation, as shown in Figures 2, 9, and 10, the assembly module further includes:

[0112] The cushioning foam 400 is disposed on the first support side and is located between the outer support plate 120 and the cover plate 20.

[0113] In some embodiments of this disclosure, as shown in Figures 2, 9, and 10, a buffer foam 400 is provided on the first support side, supporting the outer support plate 120 and the cover plate 20. On one hand, the deformation of the buffer foam 400 can further offset the angular difference between the assembly angle and the manufacturing angle, ensuring the flatness of the outer support plate 120; and further buffering the compressive stress, preventing the compressive stress from being transmitted to the display module 30 through the outer support plate 120 and the cover plate 20, further preventing the display module 30 from developing yellow spots and / or light leakage defects due to uneven stress. On the other hand, the buffer foam 400 can seal the gap between the cover plate 20 and the first support side, improving sealing and preventing the entry of foreign objects.

[0114] In some embodiments of this disclosure, optionally, as shown in Figures 2, 9 and 10, adhesive layers may be provided on both sides of the cushioning foam 400, and the two sides of the cushioning foam 400 may be bonded to the first support side and the cover plate 20 respectively through the adhesive layers.

[0115] As an optional implementation, as shown in Figures 9 to 18, the assembly module further includes: a middle frame 500, which includes an inner side plate 510 and an inner support plate 520 connected to the inner side; the inner side plate 510 is located on the side of the connecting plate 220 near the first transition part 311, and the inner side plate 510 has a first transition clearance groove 511 corresponding to the position of the first transition part 311; the inner support plate 520 is located on the side of the rear plate 210 away from the connecting plate 220, and the inner support plate 520 is used to support the display module 30.

[0116] In some embodiments of this disclosure, as shown in Figures 9, 10, 12 and 16, the assembly module further includes a middle frame 500. The middle frame 500 includes an inner side plate 510 and an inner support plate 520 connected to the inner side. The inner side plate 510 is located on the side of the connecting plate 220 near the first transition portion 311, and the inner support plate 520 is located on the side of the rear plate 210 away from the connecting plate 220. The inner support plate 520 is used to support the display module 30.

[0117] In some embodiments of this disclosure, as shown in Figures 9, 10, 12, and 16, at the connection between the first adapter portion 311 of the adapter plate 310 and the connecting plate 220, the presence of the inner side plate 510 of the middle frame 500 interferes with the connection between the first adapter portion 311 and the connecting plate 220. By providing a first adapter clearance groove 511 corresponding to the position of the first adapter portion 311 in the inner side plate 510, the first adapter portion 311 can be directly connected to the connecting plate 220 by avoiding the first adapter portion 311 through the first adapter clearance groove 511. Compared with the traditional method of indirect connection between the adapter plate 310 and the back plate 200 / connecting plate 220 through the middle frame 500, the embodiments of this disclosure directly connect the first adapter portion 311 to the connecting plate 220, which can reduce the compression of the middle frame 500 after the adapter plate 310 is locked and avoid the transmission of compressive stress to the display module 30 through the middle frame 500, thereby further reducing the risk of yellow spots and / or light leakage in the display device.

[0118] In some embodiments of this disclosure, as shown in Figures 9, 10, 12, and 16, a panel buffer pad 522 may be provided on the side of the inner support plate 520 near the display module 30 to support the display module 30. A backlight buffer pad 523 may be provided on the side of the inner support plate 520 near the backlight module 40 to restrict the position of the backlight module 40 through the buffer pad of the back plate 200, preventing the backlight module 40 from shifting.

[0119] As an optional implementation, as shown in Figures 15 to 18, the middle frame 500 further includes a first nested plate 521 connected to the inner support plate 520 and extending toward the rear plate 210; the back plate 200 further includes a second nested plate 230 connected to the rear plate 210 and extending toward the inner support plate 520, the second nested plate 230 being located between the inner side plate 510 and the first nested plate 521.

[0120] In some embodiments of this disclosure, as shown in Figures 15 to 18, the middle frame 500 includes a first nested plate 521 connected to the inner support plate 520 and extending toward the rear plate 210; the back plate 200 includes a second nested plate 230 connected to the rear plate 210 and extending toward the inner support plate 520. After the assembly module is assembled, the second nested plate 230 can be located between the inner side plate 510 and the first nested plate 521, that is, the first nested plate 521 and the second nested plate 230 are interlocked, which can form a tortuous groove-shaped sealed space between the middle frame 500 and the back plate 200. This tortuous groove-shaped sealed space can effectively prevent foreign objects from entering the interior of the assembly module, improve the foreign object entry resistance of the assembly module, and enable the assembly module to meet the application scenarios with more stringent requirements for foreign objects, such as medical display devices. In addition, the back panel 200 often has several perforated structures for fixing or engaging various films of the backlight module 40 and / or display module 30. Through the interlocking structure of the first nesting plate 521 and the second nesting plate 230, the perforated structures on the back panel 200 are covered, and the perforated structures on the back panel 200 are wrapped to prevent foreign objects from entering the assembly module through the perforated structures. There is no need to stick dustproof tape or other dustproof structures on the perforated structures of the back panel 200, which can reduce the workload and reduce product costs to a certain extent.

[0121] In some embodiments of this disclosure, as shown in Figures 15 to 18, the first nesting plate 521 and the second nesting plate 230 can be intermittently arranged according to the position of the perforation structure on the back plate 200. That is, the middle frame 500 can be provided with multiple first nesting plates 521, and the back plate 200 can be provided with second nesting plates 230 that correspond one-to-one in number and position to the first nesting plates 521, thereby forming a groove-shaped sealed space corresponding to the position of the perforation structure.

[0122] As an optional implementation, as shown in Figures 1, 19 and 20, the assembly module also includes a protective cover 600. The protective cover 600 is connected to the side of the rear plate 210 away from the cover plate 20 and forms a protective cavity between the protective cover 600 and the rear plate 210. The protective cover 600 is provided with a second transition avoidance groove for avoiding the second transition part 312.

[0123] In some embodiments of this disclosure, as shown in Figures 1, 19 and 20, the assembly module further includes a protective cover 600. By connecting the protective cover 600 to the side of the rear plate 210 away from the cover plate 20 and forming a protective cavity between the protective cover 600 and the rear plate 210, the protective cavity can be used to arrange structures that need to be protected, such as circuit boards (PCBs) and / or chip on film (COF311), according to design requirements. Meanwhile, the protective cover 600 is provided with a second transition clearance groove for avoiding the first transition part 311. Thus, a protective cavity is formed between the protective cover 600 and the back plate 210 for the assembly process of the back plate 200 and the outer frame 100 after the PCB and / or COF311. Since the protective cover 600 is provided with a second transition clearance groove for avoiding the second transition part 312, it is not necessary to remove the protective cover 600. The protective cover 600 is left on the back plate 200, so that the protective plate and the back plate 200 form an integrated protective structure to wrap and protect the PCB and / or COF311. Thus, the design of the protective cover 600 is compatible with both the shipment of the display module 30 and the shipment of the complete display device, achieving a compatible design and effectively reducing costs. At the same time, it can also protect the PCB and / or COF311 in real time during the assembly process of the back plate 200 and the outer frame 100, improve the yield of the assembly process, and simplify the assembly steps.

[0124] Based on the same inventive concept, this disclosure also proposes a display device, as shown in Figures 1, 9 and 20. The display device includes a cover plate 20, a display module 30, a backlight module 40 and the aforementioned assembly module. The display module 30 is located on the side of the cover plate 20 near the back plate 210; the backlight module 40 is located between the display module 30 and the back plate 210.

[0125] Since the display device provided by the present invention includes the assembly module of the above-mentioned technical solution, the display device provided by the present invention has all the beneficial effects of the above-mentioned assembly module, which will not be elaborated here.

[0126] As an optional implementation, as shown in FIG1, the display device further includes a plurality of functional card plates 50 connected to the display module 30, and the functional card plates 50 are located on the side of the rear plate 210 away from the cover plate 20.

[0127] In some embodiments of this disclosure, as shown in FIG1, FIG9 and FIG20, the display device may be provided with a plurality of functional cards 50 on the side of the back plate 200 away from the cover plate 20. The functional cards 50 may include any one or more of the following: system board 51, serial digital interface (SDI) video acquisition card, timing control circuit board 53 and constant current board 54.

[0128] In some embodiments of this disclosure, optionally, as shown in FIG1, the timing control board can be disposed on the side of the back plate 200 away from the cover plate 20 and located in the middle area of ​​the back plate 200. The timing control board can be connected to the circuit board of the display panel through a long flexible circuit board (FFC) line, thereby providing an installation position for the SDI video capture card 52 in the lower area of ​​the side of the back plate 200 away from the cover plate 20, so that the SDI video capture card 52 is disposed separately from the timing control board, avoiding the need to stack the SDI video capture card 52 on the side of the timing control board away from the back plate 200, thereby reducing the overall thickness of the display device.

[0129] In some embodiments of this disclosure, the distribution of each functional card 50 on the side of the back plate 200 away from the cover plate 20 can be planned in a coordinated manner. For example, other cards in the functional card 50 can also be set separately from the SDI video acquisition card 52 and the timing control board, so as to make reasonable use of the space on the side of the back plate 200 away from the cover plate 20 and reduce the overall thickness of the display device.

[0130] As an optional implementation, as shown in Figures 1, 19 and 20, the assembly module further includes a protective cover 600. The protective cover 600 is connected to the side of the rear plate 210 away from the cover plate 20 and forms a protective cavity between the protective cover 600 and the rear plate 210.

[0131] In some embodiments of this disclosure, as shown in Figures 1, 19 and 20, the assembly module further includes a protective cover 600. By connecting the protective cover 600 to the side of the rear plate 210 away from the cover plate 20 and forming a protective cavity between the protective cover 600 and the rear plate 210, the protective cavity can be used to arrange structures that need to be protected, such as circuit boards (PCBs), chip on film (COF311) and function card boards 50, according to design requirements. Meanwhile, the protective cover 600 is provided with a second transition clearance groove for avoiding the first transition part 311. Thus, a protective cavity is formed between the protective cover 600 and the back plate 210 for the assembly of the back plate 200 and the outer frame 100 after the PCB, COF311 and the functional card plate 50. Since the protective cover 600 is provided with a second transition clearance groove for avoiding the second transition part 312, it is not necessary to remove the protective cover 600. The protective cover 600 is left on the back plate 200, so that the protective plate and the back plate 200 form an integrated protective structure to wrap and protect the PCB, COF311 and the functional card plate 50. Thus, the design of the protective cover 600 is compatible with both the shipment of the display module 30 and the shipment of the complete display device, realizing a compatible design and effectively reducing costs. At the same time, it can also protect the PCB and / or COF311 in real time during the assembly of the back plate 200 and the outer frame 100, improve the yield of the assembly process, and simplify the assembly steps.

[0132] As an optional implementation, the display module 30 includes a display panel, which is a liquid crystal display panel.
