[0044] Please refer to Figure 1 and Figure 2, an embodiment of the present application provides a display device 100, including a housing 10, an elastic buckle 20, and a backplane 30. A first engaging groove 151 is provided inside the housing 10. The elastic buckle 20 includes a first engaging portion 23, and the first engaging portion 23 is engaged with the first engaging groove 151. The elastic buckle 20 is connected to the backplane 30.

[0045] Please refer to Figure 1 , the display device 100 may further include a display panel 40, and the display panel 40 is disposed on a side of the backplane 30 away from the housing 10. Exemplarily, the display panel 40 is a liquid crystal display panel.

[0046] Please refer to Figure 1 , the housing 10 may be the rear shell of the display device 100.

[0047] Exemplarily, there is a gap between the backplane 30 and the display panel 40, and an optical film group and a light source are provided in this gap. The light emitted by the light source passes through the optical film group and then displays image information on the display panel 40.

[0048] Exemplarily, the display device 100 may be a terminal such as a television, a mobile phone, a tablet computer, etc., and may also be a gaming device, an Augmented Reality (AR) device, a Virtual Reality (VR) device, a data storage device, an audio playback device, a video playback device, a wearable device, etc. with a display screen. Among them, the wearable device may be a smart bracelet, smart glasses, a smart watch, smart decoration, etc.

[0049] For the display device 100 provided by the embodiment of the present application, by using the elastic buckle 20 to connect the backplane 30 and the housing 10, a first engaging groove 151 is provided inside the housing 10, and the first engaging groove 151 is engaged with the first engaging portion 23 of the elastic buckle 20. Since the elastic buckle 20 is prone to deformation when pressed, when the display device 100 is repaired, the elastic buckle 20 can be easily separated from the housing 10, and then the housing 10 and the backplane 30 can be separated. The housing 10 is not easily damaged during the disassembly process. Therefore, the maintainability of the display device 100 can be improved. Moreover, since the first engaging groove 151 on the housing 10 is located inside the first plate body 111, the outer surface of the housing 10 is flat and smooth, and no destructive structures such as screw grooves and connection holes need to be provided, thereby improving the appearance beauty of the housing 10, and further improving the appearance beauty of the display device.

[0050] It can be understood that since the elastic buckle 20 and the housing 10 are connected by an engaging connection method, when the elastic buckle 20 is damaged, only the elastic buckle 20 needs to be replaced instead of the entire housing 10, and the maintenance cost is relatively low.

[0051] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 wherein the housing 10 includes a first plate member 11 and a second plate member 12 which are stacked and connected. The first plate member 11 faces the back plate 30. The first plate member 11 includes a first plate body 111 and a first protrusion 112. The first protrusion 112 is connected to the first plate body 111 and protrudes towards the back plate 30. An inner surface of the first protrusion 112 and the second plate member 12 define the first engaging groove 151. The first protrusion 112 is provided with a first through hole 141 which communicates with the first engaging groove 151.

[0052] It can be understood that since the second plate member 12 is located outside the first engaging groove 151, the user cannot see the first engaging groove 151 from the outside. At this time, the outer surface of the second plate member 12 is the outer surface of the housing 10. Since the outer surface of the second plate member 12 is flat, the outer surface of the housing 10 seen by the user is flat, thus improving the overall aesthetic appearance of the display device 100.

[0053] Please refer to Figure 2 、 Figure 5 and Figure 6 wherein the first protrusion 112 includes a first side plate 120 and a first top plate 130. One side of the first side plate 120 is connected to the first plate body 111, and the other side is connected to the first top plate 130. The first through hole 141 is provided on the first top plate 130.

[0054] Please refer to Figure 2 、 Figure 6 and Figure 12 wherein the elastic buckle 20 further includes a buckle body 21 and a first connecting portion 22. Two ends of the first connecting portion 22 are respectively connected to the buckle body 21 and the first engaging portion 23. The first connecting portion 22 passes through the first through hole 141. The first engaging portion 23 is disposed in the first engaging groove 151. A positive projection of the first engaging portion 23 on a plane where the first plate body 111 is located and a positive projection of the buckle body 21 on a plane where the first plate body 111 is located are both larger than a positive projection of the first through hole 141 on a plane where the first plate body 111 is located.

[0055] Please refer to Figure 2 、 Figure 6 and Figure 12, a gap is provided between the first connecting portion 22 of the elastic buckle 20 and the pore wall of the first through hole 141, and a gap is provided between the first engaging portion 23 of the elastic buckle 20 and the groove wall of the first engaging groove 151.

[0056] It should be noted that by designing a gap between the first connecting portion 22 of the elastic buckle 20 and the pore wall of the first through hole 141, and a gap between the first engaging portion 23 of the elastic buckle 20 and the groove wall of the first engaging groove 151, the elastic buckle 20 can move within the first through hole 141 and the first engaging groove 151. When the elastic buckle 20 is clamped with the back plate 30 and the position of the second engaging portion 25 of the elastic buckle 20 in the second engaging groove 306 of the back plate 30 is offset, since the elastic buckle 20 itself has elasticity and the elastic buckle 20 can move relatively within the first through hole 141 and the first engaging groove 151, the elastic buckle 20 can correct itself using its own elasticity, so that the position of the second engaging portion 25 of the elastic buckle 20 in the second engaging groove 306 of the back plate 30 is restored to the preset position.

[0057] Exemplarily, the first connecting portion 22 is cylindrical, that is, the cross section of the first connecting portion 22 is circular, the first through hole 141 is a round hole, and the diameter of the first through hole 141 is slightly larger than the diameter of the cross section of the first connecting portion 22, so as to keep a gap between the first connecting portion 22 of the elastic buckle 20 and the pore wall of the first through hole 141.

[0058] Exemplarily, both the first engaging groove 151 and the first engaging portion 23 are cylindrical, that is, the cross sections of the first engaging groove 151 and the first engaging portion 23 are circular, and the diameter of the cross section of the first engaging groove 151 is slightly larger than the diameter of the cross section of the first engaging portion 23, so as to keep a gap between the first engaging portion 23 of the elastic buckle 20 and the groove wall of the first engaging groove 151.

[0059] Please refer to Figure 4 , the first side plate 120 has a first opening 121, the first opening 121 communicates with the first engaging groove 151, the first top plate 130 has a second opening 132, and the second opening 132 communicates with the first through hole 141, so that the first engaging portion 23 passes through the first opening 121 and enters the first engaging groove 151, and the first connecting portion 22 passes through the second opening 132 and enters the first through hole 141.

[0060] Exemplarily, a guiding angle is designed at the second opening 132, so that the first connecting portion 22 of the elastic buckle 20 can more easily pass through the second opening 132 and enter the first through hole 141.

[0061] Please refer to Figure 4 , the first through hole 141 is a round hole, and the width of the second opening 132 is smaller than the diameter of the first through hole 141.

[0062] Please refer to Figure 4 , a guiding groove 125 is further provided on the housing 10, and the guiding groove 125 communicates with the first opening 121 and the first engaging groove 151, so that the elastic buckle 20 is guided to the first opening 121 through the guiding groove 125.

[0063] Please refer to Figure 4 , a guiding hole is provided on the first plate member 11, and the hole wall of the guiding hole and the second plate member 12 jointly enclose the guiding groove 125.

The second connecting portion 24 penetrates through the second through hole 305. The second engaging portion 25 is disposed in the second engaging groove 306. The orthographic projection of the second engaging portion 25 on the plane where the third plate body 31 is located and the orthographic projection of the buckle body 21 on the plane where the third plate body 31 is located are both larger than the orthographic projection of the second through hole 305 on the plane where the third plate body 31 is located.

[0068] Please refer to Figure 2 , Figure 10 and Figure 12 , the second protruding portion 32 includes a second side plate 321 and a second top plate 322. One side of the second side plate 321 is connected to the third plate body 31, and the other side is connected to the second top plate 322. The second through hole 305 is provided on the second top plate 322.

[0069] Please refer to Figure 2 , Figure 10 and Figure 12 , the second top plate 322 includes a horizontal portion 301, an inclined portion 302, and a vertical portion 303 which are arranged in sequence from the outside to the inside. Two sides of the inclined portion 302 are respectively connected to the horizontal portion 301 and the vertical portion 303. In the direction from the horizontal portion 301 to the third plate body 31, the inclined portion 302 and the vertical portion 303 are arranged in sequence. The included angle between the inclined portion 302 and the horizontal portion 301 is an obtuse angle. The vertical portion 303 is annular, and the vertical portion 303 encloses the second through hole 305.

[0070] Exemplarily, the horizontal portion 301 is parallel to the third plate body 31.
