[0059] To facilitate the understanding of the solution of the present application, the spline curves and arrows used for the reference numerals in the drawings are described herein: For the components indicated by the spline curves without arrows, they are solid components, that is, components having a solid structure; for the components indicated by the spline curves with arrows, they are virtual components, that is, components without a solid structure.

[0060] In a first aspect, please refer to Figures 1 to 19 , an embodiment of the present application provides a connector 1, which is used to connect a backplane 2 and a front frame 3. Specifically, a receiving space 1a is formed on the connector 1, and the receiving space 1a is used to nest the flange 21 of the backplane 2. A first convex bump 1b and a second convex bump 1c extending into the receiving space 1a are further provided on the connector 1. The first convex bump 1b is used to be snap-connected with the card hole 22 on the flange 21, and the second convex bump 1c is used to cooperate with the side wall of the receiving space 1a to clamp the flange 21.

[0061] The connector 1 provided by the embodiment of the present application can be snap-connected with the card hole 22 on the flange 21 by using the first convex bump 1b to achieve the first fixation between the connector 1 and the backplane 2. The connector 1 can also use the second convex bump 1c to cooperate with the side wall of the receiving space 1a to clamp the flange 21 to achieve the second fixation between the connector 1 and the backplane 2. Through the double fixation, the reliability of the connection between the connector 1 and the backplane 2 is improved, and the risk of loosening between the front frame 3 and the backplane 2 is reduced.

[0062] It should be noted here that the number of the first convex bumps 1b on the connector 1 can be one or more, and the number of the second convex bumps 1c can be one or more.

[0063] In some embodiments, please refer to Figures 1 to 4, the connecting member 1 includes a first elastic piece 11, a second elastic piece 12 and a connecting piece 13. The first elastic piece 11 and the second elastic piece 12 are arranged oppositely. The connecting piece 13 connects the first elastic piece 11 and the second elastic piece 12 and jointly defines a receiving space 1a. The first convex hull 1b is arranged on the first elastic piece 11. The first elastic piece 11 and the second elastic piece 12 in the connecting member 1 can undergo elastic deformation. In this way, when the flange 21 of the back plate 2 is inserted into the receiving space 1a, the first elastic piece 11 and the second elastic piece 12 can deform in a direction away from each other, reducing the difficulty for the flange 21 to enter the receiving space 1a. After the first convex hull 1b is engaged with the engaging hole 22, the first elastic piece 11 and the second elastic piece 12 reset and cooperate with the second convex hull 1c to clamp and fix the flange 21. Optionally, the connecting member 1 is a metal part. In this way, the connecting member 1 not only has good strength but also has good elastic deformation ability. The material of the metal part includes but is not limited to any one of copper, aluminum and steel. As an example, the first elastic piece 11, the second elastic piece 12 and the connecting piece 13 are integrally formed. For example, the connecting member 1 is obtained by stamping a metal plate. In order to ensure that the first elastic piece 11 and the second elastic piece 12 have good elastic deformation performance, the thickness of the first elastic piece 11 and the second elastic piece 12 should not be too thick. Optionally, the thickness of the first elastic piece 11 is 0.2 mm to 0.5 mm, such as 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm. Optionally, the thickness of the second elastic piece 12 is 0.2 mm to 0.5 mm, such as 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm.

[0064] Of course, in other embodiments, the connecting member 1 can also be made of plastic or other materials.

[0065] In some embodiments, please refer to Figures 1 to 4 , the connecting member 1 is U-shaped, and the first elastic piece 11 and the second elastic piece 12 are located on the same side of the connecting piece 13. Optionally, the connecting piece 13 is a continuous plate body, and the receiving space 1a is a groove with openings at both ends. Optionally, the number of the connecting pieces 13 is multiple, and the multiple connecting pieces 13 are arranged at intervals, and the receiving space 1a is a slit located between the first elastic piece 11 and the second elastic piece 12.

[0066] In some embodiments, please refer to Figures 1 to 4, the second convex hull 1c is disposed on the first elastic piece 11. The first elastic piece 11 faces the second elastic piece 12, so that the second convex hull 1c can cooperate with the second elastic piece 12 to clamp the flanging 21. In other embodiments, the second convex hull 1c may also be disposed on the second elastic piece 12. However, comparatively speaking, by disposing both the first convex hull 1b and the second convex hull 1c on the first elastic piece 11, the difficulty of connecting the connector 1 to the back plate 2 can be reduced. Optionally, both the first convex hull 1b and the second convex hull 1c are bulges formed by the local bulging of the first elastic piece 11 into the receiving space 1a, so as to ensure that the first convex hull 1b and the second convex hull 1c themselves also have a certain deformation ability.

[0067] In some embodiments, please refer to Figures 1 to 4 , the first elastic piece 11 includes a first body portion 111 and a first protruding portion 112 integrally provided. The first protruding portion 112 protrudes relative to the first body portion 111 in a direction close to the second elastic piece 12. The first convex hull 1b is disposed on the first protruding portion 112, and the second convex hull 1c is disposed on the first body portion 111. It can be understood that when the flanging 21 extends into the receiving space 1a, the first protruding portion 112 is closer to the flanging 21 than the first body portion 111. The first convex hull 1b is disposed on the first protruding portion 112, so as to ensure that the first convex hull 1b can better engage with the engaging hole 22 on the flanging 21, while the second convex hull 1c is disposed on the first body portion 111. In this way, the first body portion 111 and the first protruding portion 112 can jointly abut against the flanging 21 to ensure uniform force on the flanging 21. Optionally, the top surface of the second convex hull 1c is coplanar with the surface of the first protruding portion 112 or the top surface of the second convex hull 1c is slightly higher than the surface of the first protruding portion 112. As an example, the first protruding portion 112 is formed by bending the middle part of the first elastic piece 11 in a direction close to the second elastic piece 12.

[0068] In some embodiments, please refer to Figures 1 to 4 , Figure 8 and Figure 9, the connecting member 1 is used to be installed in the installation groove 31 of the front frame 3, and the second elastic piece 12 is used to connect with the side wall of the installation groove 31. By installing the connecting member 1 in the installation groove 31 of the front frame 3, and the second elastic piece 12 is also connected with the side wall of the installation groove 31, that is, the connecting member 1 is connected with the front frame 3, thereby realizing the connection between the back plate 2 and the front frame 3 through the connecting member 1. Here, the connection mode between the second elastic piece 12 and the side wall of the installation groove 31 can be integrally arranged or detachably connected. As an example, the connection mode between the second elastic piece 12 and the side wall of the installation groove 31 includes but is not limited to welding, snap connection, interference fit, etc. In addition, installing the connecting member 1 in the installation groove 31 of the front frame 3 can hide the connecting member 1 and prevent the connecting member 1 from being exposed to affect the appearance; at the same time, the side wall of the installation groove 31 can also limit the deformation and opening of the first elastic piece 11 and the second elastic piece 12 on the connecting member 1, thereby reducing the risk of the flanging 21 slipping out of the receiving space 1a and improving the reliability of the connection between the connecting member 1 and the back plate 2. During the assembly process of the connecting member 1 with the back plate 2 and the front frame 3, the connecting member 1 can be first fixed on the flanging 21 of the back plate 2, and then the flanging 21 connected with the connecting member 1 can be inserted into the installation groove 31.

[0069] In some embodiments, please refer to Figures 1 to 4 , Figure 8 , Figure 9 and Figure 15, the second elastic piece 12 is used for clamping with the side wall of the installation groove 31. Specifically, the second elastic piece 12 includes a second body portion 121 and a second protrusion portion 122. The second protrusion portion 122 protrudes relative to the second body portion 121 in a direction away from the first elastic piece 11, and the second protrusion portion 122 is used for clamping with the side wall of the installation groove 31. It can be understood that when the flanging 21 extends into the accommodation space 1a, the second body portion 121 is closer to the flanging 21 than the second protrusion portion 122. The second body portion 121 can cooperate with the first elastic piece 11 (such as the first protrusion portion 112) and the second convex hull 1c to clamp the flanging 21. The second protrusion portion 122 is closer to the side wall of the installation groove 31 than the second body portion 121. Furthermore, the second protrusion portion 122 can cooperate with the side wall of the installation groove 31 to achieve clamping. Optionally, a stop wall (not shown in the figure) is formed on the side wall of the installation groove 31, and the free end of the second protrusion portion 122 abuts against the stop wall, thereby achieving clamping. Optionally, a clamping groove 32 is formed by the inner depression of the inner front frame 3 on the side wall of the installation groove 31, and the second protrusion portion 122 extends into the clamping groove 32 and engages with the clamping groove 32. As an example, the second protrusion portion 122 is formed by bending the middle part of the second elastic piece 12 in a direction away from the first elastic piece 11. Taking the example that the clamping groove 32 is provided on the side wall of the installation groove 31, when assembling the connecting piece 1 and the front frame 3, the connecting piece 1 is pushed into the installation groove 31. During the pushing process, the second protrusion portion 122 is first squeezed by the side wall of the installation groove 31 and undergoes elastic deformation. When reaching the position of the clamping groove 32, the second protrusion portion 122 resets and extends into the clamping groove 32 to achieve clamping with the clamping groove 32. Compared with other connection methods, the clamping of the second elastic piece 12 with the side wall of the installation groove 31 is simple in assembly and easy to implement.

[0070] In some embodiments, please refer to Figures 1 to 4 , Figure 8 and Figure 9 , the second elastic piece 12 further includes a transition portion 123. The transition portion 123 extends obliquely from the second body portion 121 to the second protrusion portion 122 and connects the second body portion 121 and the second protrusion portion 122 together. That is to say, the second body portion 121, the second protrusion portion 122 and the transition portion 123 are integrally arranged, and the second body portion 121 smoothly transitions to the second protrusion portion 122 through the transition portion 123. The advantage of such a setting is that when it is necessary to separate the front frame 3 from the back plate 2, a small hard object (such as a blade or a metal rod) can be used to extend into the installation groove 31 through the gap between the front frame 3 and the back plate 2, and the hard object is slid along the extending direction of the installation groove 31. The hard object will sequentially slide across the surfaces of the second body portion 121, the transition portion 123 and the second protrusion portion 122. When the hard object slides across the surface of the second protrusion portion 122, the second protrusion portion 122 deforms and retracts inward and separates from the side wall of the installation groove 31, so that the front frame 3 can be separated from the back plate 2, and the disassembly is convenient.

[0071] In some embodiments, please refer to Figures 1 to 4 , the first convex hull 1b is correspondingly arranged with the transition part 123 or the second convex part 122. It can be understood that when the flanging 21 is located in the receiving space 1a, the first convex hull 1b extends into the clamping hole 22 on the flanging 21, and even the top end of the first convex hull 1b passes through the clamping hole 22 and extends to the other side of the flanging 21. Since both the transition part 123 and the second convex part 122 are far away from the flanging 21, interference with the first convex hull 1b can be prevented, thereby ensuring the clamping effect between the first convex hull 1b and the clamping hole 22.

[0072] In some embodiments, please refer to Figures 1 to 4 , the second body part 121 is connected to both ends of the second convex part 122. The second body part 121 is also directly connected to the first elastic sheet 11 through the connecting piece 13, and the second convex part 122 is separated from the first elastic sheet 11. That is to say, by directly connecting the first elastic sheet 11 to the second elastic sheet 12 through the second body part 121 via the connecting piece 13, and separating the second convex part 122 from the first elastic sheet 11, that is, there is no direct connection relationship between the two, and the second convex part 122 is only connected to the second body part 121. In this way, the elastic deformation ability of the second convex part 122 can be improved, and the difficulty of assembling and disassembling the front frame 3 and the connecting piece 1 can be increased.

[0073] As an example, the first elastic sheet 11 includes a first body part 111 and a first convex part 112 which are integrally arranged. The number of the first convex parts 112 is one, and the number of the first body parts 111 is two. The two first body parts 111 are respectively located at both ends of the first convex part 112; the second elastic sheet 12 includes a second body part 121, a second convex part 122 and a transition part 123 which are integrally arranged. The number of the second convex parts 122 is one, the number of the second body parts 121 is two, and the number of the transition parts 123 is also two. The two transition parts 123 are respectively located at both ends of the second convex part 122, and the second body part 121 is located at the end of the transition part 123 far away from the second convex part 122. Among them, the first body part 111 at the end of the first elastic sheet 11 corresponds to the second body part 121 at the end of the second elastic sheet 12, and the first body part 111 is connected to the second body part 121 through the connecting piece 13. The number of the connecting pieces 13 is two, and the two connecting pieces 13 are arranged at intervals. The first convex part 112 in the middle of the first elastic sheet 11 corresponds to the second convex part 122 in the middle of the second elastic sheet 12, and the first convex part 112 is separated from the second convex part 122. In this way, the middle part of the connecting piece 1 is hollowed out, and the two connecting pieces 13 are separated by the hollowed-out area.

[0074] In the second aspect, please refer to Figures 5 to 18, an embodiment of the present application further provides a fixing structure 10, which includes a back plate 2, a front frame 3, and the above-mentioned connecting member 1. The connecting member 1 is installed on the front frame 3. A flanging 21 is integrally provided on the back plate 2. A clamping hole 22 is formed on the flanging 21. The flanging 21 is inserted into the receiving space 1a, and the first convex bump 1b is clamped with the clamping hole 22, and the second convex bump 1c and the side wall of the receiving space 1a clamp the flanging 21.

[0075] In the fixing structure 10 provided by the embodiment of the present application, the back plate 2 is connected to the front frame 3 through the connecting member 1. Among them, the connecting member 1 uses the first convex bump 1b to be clamped with the clamping hole 22 on the flanging 21 and the second convex bump 1c to cooperate with the side wall of the receiving space 1a to clamp the flanging 21, realizing double fixation of the connecting member 1 and the back plate 2, improving the reliability of the connection between the connecting member 1 and the back plate 2, and reducing the risk of loosening between the front frame 3 and the back plate 2.

[0076] Please refer to Figure 19 , the fixing structure 10 provided by the embodiment of the present application is used to fix the display module 20 in the display device 100. The back plate 2 in the fixing structure 10 can also be called a back cover (Backcover). The back plate 2 is usually located on the back of the display device 100. The back plate 2 serves as the housing and support frame of the display device 100, and can be used to protect the internal components of the display device 100 and provide mechanical strength. The front frame 3 in the fixing structure 10 can also be called a middle frame or a front frame. The front frame 3 is usually located on the side of the display device 100, and the front frame 3 is used to fix the display panel 201 in the display module 20. As an example, please refer to Figure 14 , Figure 16 and Figure 19 , the front frame 3 is U-shaped. The front frame 3 is located on the back of the display panel 201, and the front frame 3 is used to surround three sides of the display panel 201. Since there is a circuit board or the like on the other side of the display panel 201, the front frame 3 is not provided. Optionally, in order to ensure strength, the front frame 3 is a metal frame.

[0077] A flanging 21 (also called a hem) is provided on the back plate 2. The flanging 21 is inserted into the receiving space 1a. The receiving space 1a can be used to cover and hide the flanging 21, improving the appearance of the display device 100.
